Description

Winding device

The present invention relates to a wrapping device which is mounted on a baler which bundles a linear wrapping device around a package body of a torsion bag opening and a mounted object such as a bundle body in which a wire bundle is bundled. . In detail, it is provided with a winding device having a second guiding plate which is larger than the outer shape of the first guiding plate. The brake mechanism brakes the bundle by acting in cooperation with the first brake mechanism by forming a large outer portion of the second guide plate having a larger outer shape than the first guide plate, and the package is slid by the packing device The pulling action appropriately pulls the interlocking device to perform the braking, and the braking action can suppress the wear and deformation of the wrapping device.

In the prior art, a thin iron core or the like having a plasticity is covered in a strip shape by closing a bag opening or a bundled wire, and a packing device called a twisted belt is generally used. Such a package is wound around a reel and wound. The spool is rotatably disposed with the rotating shaft inserted into its core. The package in which the spool is wound around the spool is pulled out by a predetermined length, and the spool is driven to rotate by the pull-out.

Regarding such a baler, Patent Document 1 discloses a baler that packs a label by binding (packaging). The baler has a supply reel that is packaged with a wrapper. The supply reel is provided for the shaft to be inserted into the rotating shaft. The wrapping device wound around the supply reel is pulled out and supplied to the reel while rotating.

[Patent Document 1] Japanese Patent Publication No. 44-18480 (Fig. 15)

Therefore, according to the supply reel of Patent Document 1 of the conventional example, the wrapping device wound around the supply reel is pulled out and the supply reel is driven to rotate. Therefore, after the pull-out of the baler is completed, the supply reel slightly rotates due to inertia. When the supply reel rotates slightly due to inertia, there is a problem that the pull-out line of the packing device is slack. The packing is poor due to the slack caused by the slack.

Further, there is also a baler that includes a brake mechanism that brakes a brake plate to be slidably attached to an outer peripheral portion of a single guide plate of a spool wound by a package. Therefore, in the outer peripheral portion of the guide plate on one side of the reel, since the contact area is reduced, abrasion of the reel causes deformation of the abrasion powder or the reel. Therefore, the material of the reel is mostly plastic, which is problematic from the viewpoint of disposal. Moreover, the guide plates on both sides of the reel are mostly formed in the same shape. Therefore, while the reel is set at the baler, the pull-out position (upper or lower side) of the package must be confirmed.

Accordingly, in order to solve the above problems, the present invention provides a winding device capable of suppressing deformation of a winding device caused by a braking action while lifting a braking force of the winding device.

In order to solve the above problem, in the winding device of the present invention, the wrapped package is pulled out and the rotating action is braked by the first brake mechanism to form a package having a predetermined length and is mounted on the binding machine of the binding band. The method includes: a core member; a first guiding plate disposed at one end of the core member; and a second guiding plate disposed at the other end of the core member and having a larger outer shape than the first guiding plate, wherein the forming is The large outer portion of the second guide plate having a large outer shape of the first guide plate cooperates with the first brake mechanism to brake the rotation operation.

According to the winding device of the present invention, the first guiding plate is provided at one end of the core member. The second guiding plate is disposed at the other end of the core member and has a larger outer shape than the first guiding plate. The large outer portion of the second guide plate that is formed to be larger than the first guide plate cooperates with the first brake mechanism to brake the rotation of the winding device. In this case, since the outer shape of the first guiding plate and the second guiding plate are different, the setting direction of the baler toward the winding device is clear.

According to the winding device of the present invention, the large outer portion of the second guide plate having a larger outer shape than the first guide plate cooperates with the brake mechanism to perform the rotation operation of the winding device brake.

With this configuration, since the outer shape of the first guiding plate and the second guiding plate are different, the setting direction of the baler toward the winding device is clear. Further, the winding device is slidably attached to the guide plate to increase the area in which the braking operation is generated. However, it is possible to suppress the abrasion of the winding device and the partial wear, and it is possible to suppress the generation of the abrasion powder or the deformation of the winding device. Therefore, it is possible to form a wrapping device using paper materials excellent in environment compared to resins.

Hereinafter, a description will be given of a baler according to various embodiments of the present invention with reference to the drawings.

[Example 1]

Fig. 1 is a perspective view showing the configuration of a baler 100 of a first embodiment of the present invention. The baler 100 shown in Fig. 1 is a bag 14 which is twisted by a twisted belt by two engaging holes provided in the label 1A, and the bag 13 is wrapped around the bag 14 which has been twisted by the bag mouth (refer to 5) The device for attaching the label to the fold. The bag 14 is an example of a thing to be attached. In addition to the twisted belt, the wire and wire are also suitable for the packing device 13.

The baler 100 includes a body chassis portion 92 constituting a body portion and a support portion 91 that supports the body chassis portion 92. The support portion 91 is composed of an "H"-shaped support base 91b and a support 91a vertically attached to the support base 91b. The body chassis portion 92 is attached to the front end of the pillar 91a in parallel with the support table 91b. The body chassis portion 92 is formed by a combination of a plurality of sheet metal. The main body chassis portion 92 is provided with a label supporting mechanism 2A, a label holding mechanism 3A, a label transporting mechanism 4A, a packing material transporting mechanism 5A, a packing material forming mechanism 6, a packing implement mechanism 7A, a guide plate mechanism 8A, and a label holding. Drive mechanism 9A and reel 52. Further, the packing device conveying mechanism 5A, the packing device forming mechanism 6A, the packing device contracting mechanism 7A, and the control portion 110 are examples of the packaging device. Moreover, the packing conveyance mechanism 5A and the control part 110 are an example of a pull-out apparatus. Moreover, the packing conveyance mechanism 5A and the control part 110 are an example of a pull-out apparatus. Further, the spool 52 is an example of a winding device.

The label support mechanism 2A is provided in the label holding mechanism 3A and the label transport mechanism 4A, and is used to hold the label during label transport. The label transport mechanism 4A is an example of a label transport device, and for example, the label 1A is transported from the cassette 40 to the label holding mechanism 3A. The label transport mechanism 4A is provided on the lower side of the front surface of the main body chassis portion 92 (the left side of the paper surface in Fig. 6). The label transport mechanism 4A has a cassette 40 that accommodates a plurality of labels 1A. In this example, the label transport mechanism 4A transports the stored labels 1A one by one to the label holding mechanism 3A every time the processing is completed.

The label holding mechanism 3A is provided on the front upper side of the body chassis portion 92 so as to face the transport mechanism 4A via the body chassis portion 92. The label holding mechanism 3A holds the label 1A conveyed by the label transport mechanism 4A and moves toward the package forming mechanism 6A. After the label holding mechanism 3A is moved, the packing 13 wound around the spool 52 is carried.

The spool 52 includes a core (52a) of an example of a core member (see FIG. 10A), a small-diameter disk inner plate 52c provided at one end of the core 52a, and a large-diameter disk provided at the other end of the core 52a. Trail 52b. The small-diameter disc inner plate 52c is an example of the first guide plate. The large-diameter disk outer plate 52b is an example of the second guide plate, and is formed to have a larger outer shape than the small-diameter disk inner plate 52c. The packing 13 is held around the core 52a and held. The core 52a of the spool 52, the disc inner panel 52c and the disc outer panel 52b are formed of a paper material such as a segment jam. The spool 52 is rotatably provided to the spool setting mechanism 90A. In this example, the reel setting mechanism 90A is an example of a setting mechanism, and the reel 52 has a rotation axis which is substantially horizontal, and the reel 52 is provided. The reel setting mechanism 90A has a support lever 90a, a pressing lever 90b, a side panel 90c, and a rotating shaft 90d. The support rod 90a and the rotating shaft 90d are fixed to the side panel 90c. The pressing lever 90b is an example of a pressing member, and the rear end opening portion 90f is rotatably attached to the rotating shaft 90d. Further, the pressing lever 90b has a U-shaped distal end portion 90g at the distal end thereof fitted and fixed to the distal end of the support rod 90a.

The push lever 90b is rotated to a slightly horizontal state, and in the spool 52, the support rod 90a is inserted into the core 52a from the side of the small-diameter disc inner plate 52c. Thereafter, the pressing lever 90b in a slightly horizontal state is rotated to the vertical state as shown in Fig. 1, and the U-shaped distal end portion 90g is fitted to the distal end of the support rod 90a to be fixed. Thus, the reel 52 is provided to the reel setting mechanism 90A. Further, in the spool setting mechanism 90A, the side panel 90c is attached to the body chassis portion 92 via an arm (not shown).

Further, a brake mechanism 89A is attached to the side panel 90c of the reel setting mechanism 90A. The brake mechanism 89A is an example of the first brake mechanism, and the packing tool 13 is pulled out to brake the rotating reel 52. The brake mechanism 89A is composed of a solenoid 89a and a pressing lever 90b. The solenoid 89a is an example of a first telescopic operation member and is a rising type solenoid. The solenoid 89a is disposed above the small-diameter disc inner plate 52c of the spool 52. A brake pad 90h is provided at the tip end of the movable iron core (plunger) 89c of the solenoid 89a (see Fig. 12B). The large diameter disc outer diameter 52b of the spool 52 is located between the brake pad 90h and the pressing lever 90b. That is, the disk outer plate 52b having the diameter of the spool 52 is sandwiched by the brake pad 90h of the solenoid 89a and the pressing lever 90b.

The control unit 110 (see FIG. 49) controls the energization or the interruption of the energization to perform the expansion and contraction operation at a predetermined timing, and the disc outer plate 52b is sandwiched by the solenoid 89a that cooperates with the pressing lever 90b. Large outer portion 52e. When the solenoid 89a is energized, the movable iron core 89c contracts and operates. For example, the movable iron core 89c moves toward the fixed iron core by a magnetic force generated when a current flows into a coil (not shown) and acts on a fixed iron core (not shown). When the coil is continuously energized, the movable iron core 89c is kept in a state of being adsorbed to the fixed iron core. When the energization is interrupted, the spring force of the compression spring 89b (refer to FIG. 12B) of the biasing movable iron core 89c is pushed to the original position and is elongated.

For example, when the packing tool 13 is pulled out, the solenoid 89a is energized to cause the movable iron core 89c to contract and operate. Thereby, the braking state of the reel 52 is released. When the drawing of the packing tool 13 is completed, the energization of the solenoid 89a is blocked, and the movable iron core 89c is extended. Thereby, the brake pad 90h of the movable iron core 89c abuts against the large outer portion 52e of the disk outer plate 52b of the spool 52, and the disk outer plate 52b is sandwiched by the pressing lever 90b. The brake 52 is braked. Thereby, after the packing 13 of the reel 52 is pulled out, the reel 52 does not rotate (rotate rotation) due to inertia, and the packing 13 can be prevented from slack. However, since the brake pad 90h abuts against the flat portion of the disk outer plate 52b of the spool 52, the braking force acts as compared with the outer peripheral portion (edge) of the disk outer plate 52b of the spool 52 as in the prior art. The mechanism can suppress the abrasion powder generated by the abrasion of the reel 52. Moreover, the deformation of the spool 52 can be suppressed as compared with the brake mechanism of the outer peripheral portion of the prior art.

The packing conveyance mechanism 5A is attached to the vicinity of the reel 52, and the packaging tool 13 that is wound and held on the reel 52 is pulled out, and the label holding mechanism 3A that has moved the packaging tool forming mechanism 6A conveys the packaging tool 13 and operates. The carried package 13 passes through the label 1A held by the label holding mechanism 3A.

The packing device forming mechanism 6A is disposed at a position to be engaged with the label holding mechanism 3A, and cuts the packing 13 that has passed through the label 1A so that the cutting piece 13' is cut away from the packing 13 on the side of the reel 52. The rear end portion is supplied to the packing implement contracting mechanism 7A in proximity to the front end portion. The package attachment mechanism 7A is provided in the vicinity of the package forming mechanism 6A, and the package forming mechanism 6A twists and couples the rear end portion and the front end portion of the immediately adjacent packaged package 13'.

The guide mechanism 8A is attached to the intermediate chassis portion 92a, and guides the tag 1A and the bag 14 to the mounting space portion 92b (see Fig. 38). The label holding drive mechanism 9A supplies a driving force to the label holding mechanism 3A and the package forming mechanism 6A at the time of label conveyance or packaging. In this manner, the package 100 is formed such that the package 13 is passed through the label 1A, and the cut package 13' is wound around the bag 14 to which the fold is twisted to attach the label 1A to the bag 14.

2A and 2B are explanatory views of a configuration example of the tag 1A used in the baler 100. Figure 2A is a front view of the label 1A.

The label 1A shown in FIG. 2A is formed by integrally forming the information presentation unit 10A, the attachment portion 11A, and the connection portion 12A with a thin plate material such as paper or plastic. The connecting portion 12A is a region surrounded by two broken lines shown in FIG. 2A. This area is defined by the boundary line between the attachment portion 11A and the connection portion 12A and the boundary line between the connection portion 12A and the information presentation portion 10A. In the information presentation unit 10A, various information is indicated by printing or the like. Further, a sealing member printed with various kinds of information is attached. Further, it is also possible to record information such as a braille.

Engagement holes 11m are provided at two positions on the attachment portion 11A, and the cut package 13' is engaged with the engagement holes 11m. When the longitudinal direction of the label 1A shown in FIG. 2 is the longitudinal direction, the engagement hole 11m forms two through holes at a predetermined interval in the lateral direction of the label 1A. In the connecting portion 12A, a part of both sides of the information presenting portion 10A is cut out to have a predetermined shape to form a concave portion 12m, and the mounting portion 11A and the information presenting portion 10A are connected to each other with a narrower width than the information presenting portion 10A. The recessed portion 12m is formed by forming a square-shaped groove portion on one of both sides of the information presentation portion 10A. Further, a perspective view of the tag 1A is shown in Fig. 2B.

Fig. 3 is a perspective view showing a structural example of the packing device 13. The packing device 13 shown in Fig. 3 is called a twist tie or the like, and is formed by covering a thin wire 13a of a core such as a plastic metal or resin with a covering material 13b such as resin or paper. The packing device 13 is in the form of a strip having a small width and is passed through the engaging hole 11m of the label 1A to be joined to the bag 14.

Next, a function example of the baler 100 will be described with reference to FIGS. 1 and 4 . 4A to 4D are drawings showing a function example of the baler 100.

Fig. 4 is a perspective view showing an example of movement of the label 1A toward the fold of the bag 14. In this example, the label transport mechanism 4A shown in FIG. 1 transports the label 1A to the label holding mechanism 3A, and the label holding mechanism 3A holds the label 1A and moves toward the package forming mechanism 6A.

Fig. 4B is a perspective view showing an example in which the packing tool 13 is inserted into the label 1A. In this example, the packing device conveying mechanism 5A shown in Fig. 1 pulls the packing 13 around the reel 52 about 80 mm, and the leading end of the packing 13 passes through the two engaging holes 11m of the label 1A. .

Fig. 4C is a perspective view showing an example of a structure before twisting of the packing 13 passing through the label 1A. In this example, the full length of the packing 13' is set, for example, to about 80 mm. The packing 13 of the label 1A shown in Fig. 4C is cut from the front end at a portion of about 80 mm, and the rear end portion of the cut package 13' is formed close to the front end portion. For example, after the front end of the packing device 13 passes through the engaging hole 11m of one side, the traveling direction of the packing member 13 is U-turned in accordance with the shape of the label holding mechanism 3A, and the front end of the packing member 13 passes through the other side. The engagement hole is 11m. After the insertion, the package forming mechanism 6A shown in Fig. 1 is cut at a predetermined position of the package 13. After the cutting, the package forming mechanism 6A causes the both ends of the package 13' to be close to the bag 14, and the shape of the cut package 13' is restricted to a U shape. Further, after the packing process of the packing 13', the torsion arm 70 shown in Fig. 4C having the S-shaped portion 70a at the tip end portion is used.

Fig. 4D is a perspective view showing an example of the formation of the package forming mechanism 6A shown in Fig. 1. According to the connection example shown in Fig. 4D, the rear end portion and the front end portion of the packaged article 13' which has been cut into a U shape are twisted and joined by the packing and contracting mechanism 7A. In this example, the S-shaped portion 70a of the torsion arm 70 shown in Fig. 4C is for holding both end portions of the packing member 13' restricted to the U shape, and the torsion arm 70 is rotated by a predetermined number of rotations. Thereby, the packing member 13' is twisted and joined, and the label 1A is fixed to the folding opening by the packing 13'. Thus, the label 1A can be fixed while the flap of the bag 14 is automatically packaged.

Fig. 5 is a perspective view showing an example of mounting of the label 1A. At the bag 14 shown in Fig. 5, the package 13' is joined, and the label 1A is attached by the packing 13'. In the label 1A, since the packing 13' passes through the engaging holes 11m at the two positions, the bag opening of the bag 14 is packed by the packing 13', so that the direction of the information presenting portion 10A is longitudinal along the bag 14. Not horizontal.

Further, in the label 1A, the bag 14 is twisted to form a rod-shaped pocket, and the package 13' is wound around the package, and the attachment portion 11A is bent in a shape twisted by the bag 14. Therefore, between the mounting portion 11A and the information presentation portion 10A, the concave portion 12m is formed on both sides of the information presentation portion 10A, and the information presentation portion 10A does not imitate the connection portion 12A having a narrower width than the information presentation portion 10A. The curved shape of the mounting portion 11A makes it difficult for the information presentation portion 10A to be greatly bent. Thereby, the information of the information presentation unit 10A described in the tag 1A is clearly identified. Then, since the information presentation portion 10A is not bent and along the longitudinal direction of the bag 14, the appearance of the posture in which the label 1A is attached to the bag 14 is good.

Next, a configuration example of a main part of the baler 100 and an operation example thereof will be described with reference to FIGS. 6 to 9. Fig. 6 is a top view showing a configuration example (before packing) of the baler 100 and an operation example thereof. The baler 100 shown in Fig. 6 is a view of the baler 100 shown in Fig. 1 as viewed from above. The baler 100 is in a standby state. In the standby state of the baler 100, the label transport mechanism 4A transports the label 1A in one piece to the label holding mechanism 3A.

The label holding mechanism 3A has a curling guide 30 slidably mounted to the intermediate chassis 92a constituting the body portion, and the label 1A is placed on the package forming mechanism 6A or the like by the linear motion of the curling guide 30, adjacent thereto. The packaged packaging mechanism 7A is a packaged bag 13' of the cut-off bag 14 with a twisted band. The curl guide 30 stands by at the position of the home position HP shown in Fig. 6. In Fig. 6, the original position HP of the curl guide 30 is a state in which the guide 42a (refer to Fig. 27A) of the label transport mechanism 4A is closed, and the curl guide 30 is separated from the guide 95 and moved to the leftmost side. . That is, the front end portion of the curl guide 30 is in a position to stand by on the upper extension line of the guide 42a in the closed state.

In this example, the label holding drive mechanism 9A is provided, and in order to move the curl guide 30 in the direction of the arrow Q1, the actuation plate 32 includes the proximity motor 93, the guide shaft 94, and the torque limiter 33 (refer to Fig. 37). .

In this example, the gear 93a is coupled to the output shaft of the motor 93, and the gear 94a is meshed with the gear 93a. The gear 94a is coupled to the guide shaft 94. The actuating plate 32 is slidably screwed to the inverted screw shaft 94. The sliding motion of the actuating plate 32 is transmitted to the curling guide 30 via the torque limiting member 33. The curling guide 30 receives the action of the actuating plate 32 and moves in a direction of approaching and separating with respect to the facing packer 6A.

The guide mechanism 8A is slidably attached to the front of the package forming machine 6A. The guide mechanism 8A detects the sliding movement by the position sensor for the guide shown in Fig. 39 (hereinafter referred to as the guide sensor 107). The guide sensor 107 forms the function of the detecting means.

By the guide sensor 107, when the user arranges the bag 14 in the packing opening 103 shown in Fig. 6, the bag 14 is temporarily pressed by the guide 95 during the arrangement. When the bag 14 is disposed at the packing opening 103, the guide plate 95 automatically returns to the state of the drawing. This reciprocating motion is detected by the guide sensor 107, whereby it can be determined that the bag 14 is correctly disposed at the packing opening 103.

At this point in time, the baler 100 begins the packaging process. In this example, by the bag sensor 108 (refer to Fig. 37), it is detected that the bag 14 is inserted into the packing opening 103 or discharged from the packing opening 103. Further, the guide plate 95 judges that the bag 14 in the baler 100 is correctly placed in the packing port while maintaining the pressing state, and does not start the packaging process. In this way, poor packaging can be avoided.

Further, a pair of label pulling claw portions (hereinafter referred to as label hanging claw portions 30b) shown in Fig. 29 are provided on the curl guide 30, and the curl guides 30 for holding the labels are reached by the label hanging claw portions 30b. The guide plate 95 is thereby prevented from falling off of the label 1A by the guide 95 and the curl guide 30.

The packing device 13 of the spool 52 is pulled out from the package carrying mechanism 5A to a predetermined position. In this example, the packing conveyance mechanism 5A includes a conveying roller 50a, a lever 50d, a belt tilting member 63, and a packing conveyance motor 50i (refer to Fig. 49).

The conveying roller 50a is disposed near the inlet of the belt tilting member 63 and is coupled to the output shaft of the package conveying motor 50i. The lever 50d is in contact with the conveying roller 50a.

In this example, the lever 50d includes a driven roller 50f and a spring 50g, and is attached to the rotatable body chassis portion 92. The lever 50d is biased counterclockwise by the spring 50g, and the driven roller 50f abuts against the conveying roller 50a. A packing tool 13 is interposed between the driven roller 50f and the conveying roller 50a. Thereby, by rotating the conveying roller 50a in the clockwise direction, the packing tool 13 is pulled out from the spool 52 and sent out to the belt tilting member 63.

Moreover, when the reel 52 is exchanged and the packing device 13 is initially passed through the belt tilting member 63, the user rotates the lever 50d clockwise to widen the driven roller 50f and the conveying roller 50a, and the reel 52 The packing 13 passes therethrough, and the front end of the packing 13 is set at the position of the cutting member 62.

The package forming mechanism 6A includes a cutter 62 and left and right proximal arms 61a and 6bb. The cutter 62 is attached to the body chassis portion 92 via the cutter links 62a to 62c (see FIG. 8) and the coupling roller 97. The connecting roller 97 is pressed together with the sliding of the actuating plate 32 by the roller arm 101 attached to the lower end portion of the actuating plate 32. When the connecting roller 97 is pressed, the cutter links 62a to 62c coupled to the connecting roller 97 actuate, and the cutter 62 attached to the tip end of the cutter link 62c shown in Fig. 8 moves and cuts. Packing tool 13.

Further, one end of the left proximal arm 61a is attached to the coupling roller 97. The shape of the proximal arm 61a is a V shape. One end of the proximal arm 61a is rotatably attached to the coupling roller 97, and the recess of the proximal arm 61a is rotatably attached to the body chassis portion 92 by a pin 105a. Further, the sector gear 97a is fixed to the concave portion of the proximal arm 61a by the pin 105a, and the sector gear 97a is meshed with the coupling gear 96a of one side. The coupling gear 96a meshes with the adjacent coupling gear 96b, and the sector gear 97b meshes with the coupling gear 96b. The L-shaped proximal arm 61b on the right side is attached to the sector gear 97b by a pin 105b.

With this configuration, when the coupling roller 97 is pushed, the left proximal arm 61a rotates counterclockwise about the pin 105a, and at the same time, the sector gear 97a also rotates counterclockwise about the pin 105a, engaging the sector. The coupling gear 96a of the gear 97a rotates in the clockwise direction. When the coupling gear 96a rotates in the clockwise direction, the coupling gear 96b rotates in the reverse stitch direction, and the sector gear 97b that meshes with the coupling gear 96b rotates clockwise around the pin 105b, and is attached to the right arm of the sector gear 97b. 61b also rotates clockwise around the pin 105b. Therefore, the left and right proximal arms 61a, 61b are closed.

Further, the left and right proximal arms 61a, 61b constitute a part of the belt tilting member 63 of the packing 13 in an open state. In this example, the left proximal arm 61a constitutes the belt tilting member 63 from the position of the cutting member 62 to the position of the connecting block 31a. The connecting block 31a is connected between the proximal arm 61a and the curling guide 30. Further, the right proximal arm 61b constitutes a terminal portion having a slope of 63. The connecting block 31b is connected between the curling guide 30 and the proximal arm 61.

The packing and contracting mechanism 7A includes a torsion arm 70 and a torsion motor 70c (refer to Fig. 49). The torsion arm 70 has an S-shaped portion 70a at the distal end (see Fig. 4), a gear 70b at the rear end, and the front end portion and the rear end portion of the packing 13' are held by the S-shaped portion 70a. The output shaft of the torsion motor 70c is meshed with the gear 70b, and the torsion arm 70 is rotated by the torsion motor 70c.

Fig. 7 is a top view showing a configuration example (after packing) and an operation example of the baler 100. The baler 100 shown in Fig. 7 cuts the package 13 while passing the package 13 through the label 1A, and packs the bag 14 with the formed package 13' to be in a packaged state. In order to move from the standby state shown in FIG. 6 to the packed state, first, in the baler 100, when the user arranges the bag 14 in the packing opening 103 shown in FIG. 6, the bag 14 and the guide are used. The mechanism 8A is temporarily pressed in, and the bag sensor 108 (refer to Fig. 52) detects the arrangement of the bag 14.

According to the baler 100, after the arrangement of the bag 14 is detected, the proximity motor 93 is rotated positively, and the guide screw shaft 94 is rotated positively via the gears 93a and 94a. The actuating plate 32 slidably screwed to the guide shaft 94 slides in the direction of the arrow Q2. The operation of the actuating plate 32 is transmitted to the curling guide 30 via the torque limiter 33 (refer to Fig. 37), and the curling guide 30 receives the action of the actuating plate 32, in the approaching direction of the facing packing forming mechanism 6A. While the home position H is moved to the packing position P1, the guide mechanism 8A is pressed in and abuts against the left and right connecting blocks 31a, 31b.

At this time, the guide mechanism 8A reaches the guide mechanism 8A by holding the label hanging claw portion 30b of the curl guide 30 of the label 1A, thereby preventing the label 1A from coming off. Further, the curling guide 30 constitutes a packing path of the packing device 13.

After the curl guide 30 is moved, the transport roller 50 is rotated by the packer transport motor 50i shown in Fig. 49, and the packer is held by the transport roller 50a and the driven roller 50f biased to the spring 50g. 13 is pulled out from the reel 52 by about 80 mm and sent out to the belt tilting member 63. At this time, the packing device 13 enters the stepped passage structure 60 composed of the left proximal arm 61a, the connecting block 31a, the curling guide 30, the right connecting block 31b, and the proximal arm 61b.

After the packing tool 13 is fed to the belt tilting member 63, the proximity motor 93 is again rotated, and the guide screw shaft 94 is rotated via the gears 93a and 94a. By the rotation of the guide shaft 94, the actuating plate 32 is further moved in the direction of the arrow Q2, and the connecting roller 97 is press-fitted by the roller arm 101 attached to the lower end portion of the actuating plate 32.

Pressed by the joining roller 97, the connecting rod is coupled to the cutting member 62 of the joining roller 97. As shown in Fig. 7, the belt tilting member 63 of the packing device 13 is inserted, and the packing tool existing in the belt tilting member 63 will be present. 13 cut off. At the same time as the cutting process, the proximal arm 61a that is engaged with the left side of the coupling roller 97 rotates in the counterclockwise direction, and at the same time, the sector gear 97a also rotates counterclockwise, and the coupling gear 96a that meshes with the sector gear 97a is Rotate clockwise.

When the coupling gear 96a rotates in the clockwise direction, the coupling gear 96b rotates in the counterclockwise direction, and the sector gear 97b that meshes with the coupling gear 96b rotates clockwise, and the proximal arm 61b attached to the right side of the sector gear 97b also Turn in a clockwise direction. Therefore, the left and right proximal arms 61a, 61b are closed, and the left and right proximal arms 61a, 61b close the ends of the packing 13' to the torsion arm 70 to restrict the shape of the packing 13' to a U shape.

The torsion arm 70 holds the front end portion and the rear end portion of the packing 13' by the S-shaped portion 70a provided at the front end portion. The torsion arm 70 is rotated a plurality of times by a torsion motor 70c (not shown) in a state where the front end portion and the rear end portion of the packing 13' are held by the S-shaped portion 70a. Thereby, the packing 13' is tied to the fold of the bag 14.

In the baler 100, after the packing 13' is engaged, the proximity motor 93 is reversed, and the guide shaft 94 is reversed via the gears 93a, 94a. The actuating plate 32 slidably screwed to the guide shaft 94 slides in the direction of the arrow Q3. Upon receiving the operation of the actuating plate 32, the curling guide 30 is moved in the separating direction with respect to the opposing packing forming mechanism 6A, and the guide mechanism 8A pressed into the side of the packing forming mechanism is released.

Further, the contact between the roller arm 101 attached to the lower end portion of the actuating plate 32 shown in Fig. 7 and the connecting roller 97 is released. Between the connecting roller 97 and the engaging shaft 97', the connecting roller 97 is often biased to the side of the engaging shaft 97', and the tension spring 122 is stretched by releasing the roller arm 101 and the connecting roller 97. When the contact is made, the link roller 97 moves in the direction of the arrow Q3. The joining roller 97 is pressed in via the cutter link 62c coupled to the cutting member 62.

When the connecting roller 97 moves in the direction of Q3, the cutting member 62 to which the link is coupled to the connecting roller 97 is retracted from the belt tilting member 63 of the packing material conveying mechanism 5A. While the cutting member 62 is retracted, the left proximal arm 61a coupled to the link roller 97 is rotated in the clockwise direction, and at the same time, the sector gear 97a is also rotated in the clockwise direction to engage the sector gear 97a. The coupling gear 96a rotates in the counterclockwise direction.

When the coupling gear 96a rotates in the counterclockwise direction, the coupling gear 96b also rotates in the clockwise direction, and the sector gear 97b engaged with the coupling gear 96b rotates in the counterclockwise direction, and is attached to the right side proximal arm 61b of the sector gear 97b. Also rotate in a counterclockwise direction. Therefore, the left and right proximal arms 61a, 61b are opened, and the left and right proximal arms 61a, 61b again constitute the step path 60.

Thereafter, the label transport mechanism 4A pulls the label 1A stored therein into a single piece and conveys it to the curl guide 30 of the label holding mechanism 3A. Thereby, the baler 100 returns to the standby state shown in FIG.

Fig. 8 is a top view showing a configuration example of the main part of the baler 100 (before packing) and an operation example thereof, which is a label holding mechanism 3A in which the baggage machine 100 in the standby state shown in Fig. 6 is taken out, and a packing tool is formed. The upper view of the mechanism and the packing and contracting mechanism 7A.

According to the packing tool forming mechanism 6A shown in Fig. 8, in order to move the cutting member 62, the cutting member links 62a to 62c, the link pins 97c and 97d, and the fixed shaft 97e are provided. The cutter 62 is rotatably attached by a support shaft 62' provided at a bending angle of the L-shaped cutter link 62c. The spring shaft 104 is attached to one end of the cutter link 62c.

The spiral spring 123 is wound around the spring shaft 104, and one end side of the spiral spring 123 is engaged with the cutter 62, and the other end side is engaged with the support shaft 62'. Thereby, the cutting member 62 is often biased in the counterclockwise direction by the scroll spring 123 with the support shaft 62' as the center of rotation.

Further, the other end of the cutter link 62c is rotatably attached to one end of the cutter link 62b by a link pin 97d.

A substantially central portion of the cutter link 62b is fixed to the body chassis 92 by a fixed shaft 97e (see Fig. 1). The other end of the cutter link 62b is rotatably coupled to the V-shaped proximal arm 61a by a link roller 97. The recess of the proximal arm 61a is rotatably attached to the body chassis portion 92 by the pin 105a. The sector gear 97a fixed to the recess of the proximal arm 61a is also rotatably attached to the body chassis portion 92 by the pin 105a.

Further, one end (rear end) of the L-shaped proximal arm 61b on the right side is rotatably attached to the body chassis portion 92 by a pin 105b. The sector gear 97b fixed to the rear end of the proximal arm 61b is also rotatably attached to the body chassis portion 92 by a pin 105b. With this configuration, when the connecting roller 97 is pressed in the direction of the arrow Q2, the cutting member links 62a to 92c are engaged with the fixed shaft 97e as a center, and the cutting member 62 is inserted into the packing member 13 from the belt inclined member 63. .

Fig. 9 is a top view showing a configuration example (after packing) of the main part of the baler 100 and an operation example thereof. In the baler 100 shown in Fig. 9, the coupling roller 97 is pressed in the direction of the arrow Q2, and the cutter link 62a coupled to the coupling roller 97 is pushed upward. The cutter link to which the link pin 97c is linearly coupled to the upwardly pushed cutter link 62a is rotated counterclockwise about the fixed shaft 97e.

The connecting rod pin 97d is coupled to the cutting member link that rotates in the counterclockwise direction The cutter link 62c of 62b is pushed downward. Thereby, the cutting member 62 which is coupled to the cutting member link 62c is also pushed downward, and the cutting member 62 is inserted into the belt biasing member 63 of the packing member 13, and the packing member 13 present in the belt tilting member 63 is cut. .

Further, as explained in Fig. 7, while the cutting member 62 is actuated, the left side proximal arm 61a of the connecting roller 97 is coupled to the pin 105a for rotation counterclockwise, and at the same time, the sector gear 97a is also reversed. When the hour hand rotates, the coupling gear 96a engaged with the sector gear 97a rotates clockwise. When the coupling gear 96a rotates clockwise, the coupling gear 96b rotates counterclockwise, the sector gear 97b that meshes with the coupling gear 96b rotates clockwise, and the proximal arm 61b attached to the right side of the sector gear 97b is also centered on the pin 105b. clockwise rotation. Therefore, the left and right proximal arms 61a, 61b are closed, and the front end portion and the rear end portion of the packing 13' are brought closer to the torsion arm 70 by the left and right proximal arms 61a, 61b.

Next, the reel 52 will be described. FIG. 10A is a perspective view showing a configuration example of the spool 52. The reel 52 shown in Fig. 10A includes a core 52a, a large-diameter disc outer panel 52b, and a small-diameter disc inner panel 52c. The spool 52 is provided at one end of its core 52a with a small-diameter disc inner plate 52c. Further, the reel 52 is provided at its other end of the core 52a with a large-diameter disc outer plate 52b. A circular opening 52d is provided in the center of the disk outer plate 52b and the disk inner plate 52c. The support rod 90a of the reel setting mechanism 90A shown in Fig. 12B is inserted into the opening 52d.

FIG. 10B is a front view showing the configuration of the spool 52. The radius of the small-diameter disk inner plate 52c shown in Fig. 10 is formed by a distance L3 shorter than the radius of the large-diameter disk outer plate 52b. When the reel 52 is provided in the reel setting mechanism 90A shown in Fig. 12, the brake pad 90h of the solenoid 89a of the brake mechanism 89A abuts against the large outer portion 52e of the disc outer plate 52b of the reel 52. That is, the brake mechanism 89A brakes the spool 52 by sandwiching the large outer portion 52e of the outer disk outer plate 52b which is larger than the disk inner plate 52c.

Further, since the disk outer plate 52b of the spool 52 is different in diameter from the disk inner plate 52c, when the spool 52 is disposed in the spool setting mechanism 90A, the direction in which the spool 52 is disposed is always kept constant. That is, the disc inner panel 52c of the spool 52 is often disposed toward the apparatus body. Thereby, the pull-out position of the packing 13 wound around the reel 52 is always kept constant. Here, when the disk outer plate 52b of the spool 52 has the same diameter as the disk inner plate 52c, it is also conceivable that the disk outer plate 52b of the spool 52 is disposed toward the apparatus body. At this time, since the pull-out position of the packing device 13 is reversed up and down, there is a problem that the pulling out of the packing device 13 is inappropriate. In the present invention, since the disk outer plate 52b of the spool 52 is different in diameter from the disk inner plate 52c, the disk inner plate 52c of the spool 52 is often disposed toward the apparatus body.

11A to 11C are perspective views of an example of assembly of the spool 52. The end surface of one side of the cylindrical core 52a shown in Fig. 11A and the disk inner plate 52c are fixed by an adhesive. Further, the other end surface of the cylindrical core 52a and the disk outer plate 52b are fixed by an adhesive. At this time, the disk outer plate 52b is aligned with the opening 52d of the disk inner plate 52c. Thereby, the reel 52 shown in FIG. 11B is formed. After the formation, as shown in Fig. 11C, the packing 13 is wound around the reel 52.

Next, the reel setting mechanism 90A and the brake mechanism 89A will be described. Fig. 12A is a perspective view showing a configuration example (part 1) of the reel setting mechanism 90A and the brake mechanism 89A. The reel setting mechanism 90A includes a support lever 90a, a pressing lever 90b, a side panel 90c, and a rotating shaft 90d as described in Fig. 1 .

The support rod 90a and the rotating shaft 90d are fixed to the side panel 90c. The pressing lever 90b is rotatably attached to the rotating shaft 90d. The pressing lever 90b shown in Fig. 12A includes a notch portion 90m and an operation portion 90k. The operation portion 90k is held by the user to rotate the pressing lever 90b. In the rotating pressing lever 90b, the notch portion 90m is placed on the placing piece 90n fixed to the fixing frame 90q of the side panel 90c. Thereby, the lever 90b is pushed to maintain its posture in a slightly horizontal state. In the reel setting mechanism 90A shown in Fig. 12A, the pressing lever 90b is rotated by 90° and maintained in a slightly horizontal state (reel setting standby state). Further, the notch portion 90m of the pressing lever 90b shown in Fig. 12A is not actually placed on the placing piece 90m of the fixing frame 90q. On the fixed frame 90q, the solenoid 89a of the brake mechanism 89A is suspended and fixed.

Fig. 12B is a front view showing a configuration example (part 1) of the reel setting mechanism 90A and the brake mechanism 89A. A groove portion 90p is provided at the front end of the support rod 90a shown in Fig. 12B. The U-shaped front end portion of the pressing lever 90b is fitted and fixed in the groove portion 90p.

Further, the solenoid 89a of the brake mechanism 89A shown in Fig. 12B is opposed to the vertical pressing lever 90b via the large outer portion 52e of the disk outer plate 52b shown in Fig. 14A, and is disposed outside the disk. The inner surface side of the plate 52b. Further, the pressing lever 90b is disposed on the outer surface side of the disk outer panel 52b.

In the solenoid 89a, a stopper 89d is provided at the front end of the movable iron core 89c. A compression spring 89b for extending the movable iron core 89c is provided between the stopper 89d and the solenoid body. The stopper 89d is positioned by abutting against the abutting plate 90e of the fixing frame 90q via the cushioning material 89e.

When the solenoid 89a thus constructed is energized, the movable iron core 89c contracts and operates. When the energization of the solenoid 89a is blocked, the stopper 89d of the movable iron core 89c is pushed out and extended to the abutting plate 90e by the compression spring 89b. Further, Fig. 12C is a side view showing a structural example (part 1) of the reel setting mechanism 90A and the brake mechanism 89A.

Fig. 13A is a perspective view showing a structural example (the second) of the reel setting mechanism 90A and the brake mechanism 89A. In the reel setting mechanism 90A shown in Fig. 13, the pressing lever 90b shown in Fig. 12 is rotated at 90° to be set to a slightly vertical state (reel setting state).

In this example, the operating portion 90k is held by the user, and the pressing lever 90b is rotated in the vertical direction. At this time, the front end circular portion 90i of the opening portion 90f is engaged with the rotation shaft 90d to rotate. This is a front end (engagement) portion of the rotating shaft 90d which is formed in a rectangular shape. The pressing lever 90b that rotates 90° in the vertical direction descends, and the opening portion 90f slides. Further, in the pressing lever 90b, the U-shaped distal end portion 90g at the distal end thereof is fitted to the groove portion 90p of the support rod 90a and fixed. Further, the rear end portion 90r of the opening portion 90f is also formed in a rectangular shape. Therefore, the movement of the pressing lever 90b in the vertical direction is restricted by forming the front end portion of the rectangular rotating shaft 90d. Thereby, the U-shaped distal end portion 90g of the pressing lever 90b is smoothly fitted to the groove portion 90p of the support rod 90a.

Fig. 13B is a front view showing a structural example (the second) of the reel setting mechanism 90A and the brake mechanism 89A. The solenoid 89a of the brake mechanism 89A shown in Fig. 13 is in a state of being electrically blocked, and the interval between the brake pad 90h of the movable iron core 89c and the pressing lever 90b is set at a predetermined distance. This interval is set to be slightly narrower than the thickness of the large-diameter disk outer plate 52b of the spool 52. Thereby, the brake pad 90h of the solenoid 89a cooperates with the pressing lever 90b, thereby sandwiching the disk outer plate 52b of the spool 52 to stop the spool 52. Further, Fig. 13C is a side view showing a structural example (the second) of the reel setting mechanism 90A and the brake mechanism 89A.

Next, an example in which the spool 52 is provided in the spool setting mechanism 90A will be described. Fig. 14A is a perspective view showing an arrangement example (the first) of the reel 52. The reel setting mechanism 90A shown in Fig. 14 is in a reel setting standby state shown in Fig. 12A. That is, the reel setting mechanism 90A is set to a state in which the posture of the pressing lever 90b is slightly horizontal. In the reel 52, the support rod 90a is inserted from the side of the small-diameter disc inner plate 52c toward the core 52a. At this time, when the reel 52 is attached to the support rod 90a from the side of the large-diameter disc outer panel 52b, the disc outer panel 52b abuts against the brake mechanism 89A, and the reel 52 cannot be provided in the reel setting mechanism 90A. Thereby, when the reel 52 is disposed in the reel setting mechanism 90A, the setting direction of the reel 52 is often kept constant. Therefore, the pull-out position of the packing 13 wound around the reel 52 is always kept constant.

Fig. 14B is a front view showing an arrangement example (the first) of the reel 52. The brake pad 90h of the solenoid 89a shown in Fig. 14B abuts against the large outer portion 52e of the large-diameter disk outer plate 52b of the spool 52.

Fig. 14C is a side view showing an arrangement example (the first) of the reel 52. As shown in Fig. 14C, the pressing lever 90b is rotated to a slightly horizontal state, and the spool 52 is slid and attached to the support rod 90a. That is, when the pressing lever 90b rotated to the slightly horizontal state slides the reel 52 and attaches it to the support lever 90a, it is not troublesome to protrude from the reel 52. Thereby, the spool 52 can be smoothly provided to the spool mounting mechanism 90A.

Fig. 15A is a perspective view showing an arrangement example (the second) of the reel 52. Fig. 15B is a front view showing an arrangement example (the second) of the reel 52. Fig. 15C is a side view showing an example of the arrangement of the spool 52.

In the reel setting mechanism 90A of Fig. 15A, the pressing lever 90b shown in Fig. 14A is rotated by 90° to be set to a slightly vertical state. In order to move to the vertical state, the operating portion 90k is held by the user, and the pressing lever 90b is rotated in the vertical direction. At this time, the front end circular portion 90i (see FIG. 13A) of the opening portion 90f is engaged with the rotation shaft 90d to rotate. The front end (engagement) portion of the rotating shaft 90d forms a rectangle which is formed to have a smaller outer shape than the inner shape of the front end circular portion 90i. In the pressing lever 90b shown in Figs. 15A to 15C, the U-shaped distal end portion 90g at the distal end thereof is not fitted to the groove portion 90p of the support rod 90a.

The pressing lever 90b has a bent portion 90j formed by bending one side end thereof to the outside. When the push lever 90b is rotated, the outer ring 52f of the disk outer plate 52b of the spool 52 is received by the bent portion 90j, and the disk outer plate 52b is slightly pressed into the solenoid 89a side. When the energization of the solenoid 89a is blocked, the movable iron core 89c is pushed out by the compression spring 89b to be elongated. Therefore, when the reel 52 is disposed in the reel setting mechanism 90A, the movable iron core 89c is elongated because the energization of the solenoid 89a is blocked. Thereby, when the pressing lever 90b is rotated, the outer ring 52f of the disk outer plate 52b of the spool 52 is received by the curved portion 90j, and the disk outer plate 52b must be slightly pressed into the side of the solenoid 89a.

Fig. 16A is a perspective view showing an arrangement example (the third) of the reel 52. Fig. 16B is a front view showing an arrangement example (the third) of the reel 52. Fig. 16C is a side view showing an arrangement example (the third) of the reel 52.

In the reel setting mechanism 90A shown in Fig. 16A, the pressing lever 90b is lowered in the vertical direction shown in Fig. 15A, and the opening 90f is slid. Further, in the pressing lever 90b, the U-shaped distal end portion 90g at the distal end thereof is fitted and fixed to the groove portion 90p of the support rod 90a. At this time, the thin groove-shaped portion formed in the opening portion 90f is engaged with the rectangular portion formed on the rotating shaft 90d, and cannot be rotated. In this way, the reel 52 is disposed on the reel setting mechanism 90A.

Next, an operation example of the brake mechanism 89A will be described. Fig. 17A is a perspective view showing an operation example of the brake mechanism 89A. Fig. 17B is a front view showing an operation example of the brake mechanism 89A. Fig. 17C is a side view showing an operation example of the brake mechanism 89A.

The solenoid 89a of the brake mechanism 89 shown in FIGS. 17A to 17C is in a state in which the movable iron core 89c is contracted. At this time, the compression spring 89b provided between the stopper 89d and the solenoid body is compressed from the state shown in Fig. 16B. Further, the brake pad 90h of the movable iron core 89c is isolated from the large outer portion 52e of the disk outer plate 52b of the spool 52. Thereby, the reel 52 is in a state in which the brake is released. That is, in the spool 52, the core 52a is supported by the support rod 90a. Then, the side of the disk outer panel 52b of the spool 52 cannot be pulled out by pressing the lever 90b, and the side of the disk inner panel 52c of the spool 52 is not pulled out by the side panel 90c.

In the brake release state, the packing 13 of the spool 52 is pulled out by the packing conveyance mechanism 5A shown in Fig. 1 . When the operation of pulling out the packing tool 13 by the packing conveyance mechanism 5A is completed, the energization of the solenoid 89a is blocked. Thereby, the movable iron core 89c is pushed out and extended by the compression spring 89b. Then, as shown in FIG. 16B, while the stopper pad 90h abuts against the large outer portion 52e of the disk outer plate 52b of the spool 52, the disk outer plate 52b is held by the pressing lever 90b to the spool 52 to brake. Thereby, after the packing 13 of the reel 52 is pulled out, since the reel 52 does not rotate due to inertia, the pulling of the packing 13 can be prevented from being slack. Further, the load applied by the brake pad 90h against the disk outer plate 52b depends on the elastic force of the compression spring 89b. According to this configuration, the effect of the braking operation can be adjusted by changing the contact area between the elastic force of the compression spring 89b and the brake pad 90h.

Thus, the baler 100 according to the present invention, its control method, and the reel 52 mountable to the baler 100 are provided with a reel 52 having a disc outer panel 52b that is larger than the disc inner panel 52c, and the brake mechanism 89A is clamped. The disk inner plate 52c also brakes the spool 52 with a large outer portion of the large disk outer plate 52b.

Therefore, the area for the braking action is increased by slidingly connecting to the disk outer plate 52b of the spool 52. Thereby, the braking force can be improved as compared with the method of performing the braking by slidingly connecting the outer peripheral portion of the guide plate of the one side as described in the prior art. However, the abrasion of the spool 52 can be suppressed, and the generation of the abrasion powder and the deformation of the spool 52 can be suppressed. Further, since the disk inner plate 52c is different from the large outer shape of the disk outer plate 52b, the direction in which the spool 52 is disposed toward the baler 100 becomes clear.

Next, a reel setting mechanism 90B different from the above-described reel setting mechanism 90A and brake mechanisms 89B to 89D different from the brake mechanism 89A will be described. In the following description, the same components are denoted by the same reference numerals in the above-described reel setting mechanism 90A and the brake mechanism 89A, and detailed description thereof will be omitted.

Fig. 18A is a perspective view showing a configuration example of the spool setting mechanism 90B and the brake mechanism 89B. Fig. 18B is a front view showing a configuration example of the reel setting mechanism 90B and the brake mechanism 89B. Fig. 18C is a side view showing a configuration example of the reel setting mechanism 90B and the brake mechanism 89B. The reel setting mechanism 90B shown in FIGS. 18A to 18C is an example of an installation mechanism, and supports a lever 90a, a pressing lever 900b, a side panel 900c, and a rotating shaft 90d.

The support rod 90a and the rotating shaft 90d are fixed to the side panel 900c. In the pressing lever 900b, the L-shaped opening portion 900f at the rear end thereof is rotatably attached to the rotating shaft 90d. The pressing lever 900b is provided with an operating portion 90k. The operation portion 90k is held by the user to rotate the pressing lever 900b. In the reel setting mechanism 90B, the pressing lever 900b is rotated at 90° to be set to a slightly horizontal state (reel setting standby state).

A brake mechanism 89B is attached to a predetermined position of the side panel 900c. This brake mechanism 89B is an example of a second brake mechanism. The inner ring 52g (an example of the outer peripheral portion) of the disk inner plate 52c and the outer ring 52f (an example of the outer peripheral portion) of the disk outer plate 52b or the inner ring 52g of the disk inner plate 52c or the outer wheel 52f of the disk outer plate 52b The brake mechanism 89B is alternately abutted.

The brake mechanism 89B is composed of a solenoid 890a and a brake plate 900h. This solenoid 890a is an example of a second telescopic operation member, and is a push type solenoid. The solenoid 890a is provided in a slightly vertical direction with respect to the core 52a, and the control unit 110 controls the energization or the interruption of energization at a predetermined timing to expand and contract.

In the solenoid 890a, the brake plate 900h is attached to the front end of the movable iron core (plunger) 890c. The brake plate 900h is an example of a first brake plate and is slidably attached to the side panel 900c.

In this example, the brake plate 900h has elongated holes 90s in the longitudinal direction at two positions, and the elongated holes 90s are fitted into the arms 90u of the support solenoid 890a so as to be movable up and down. Further, the brake plate 900h is inserted into the both end sides by the rail 90t. As such, the brake plate 900h is slidably mounted to the side panel 900c.

Further, the brake plate 900h is biased to the solenoid main body side by the tension spring 890b. In this example, the brake plate 900h is stretched to the solenoid main body side by the tension spring 890b while the movable iron core 890c of the solenoid 890a is inserted into the opening portion thereof. Thereby, the brake plate 900h moves up and down in response to the movement of the movable iron core 890c.

The brake plate 900h forms a first braking surface 901h (an example of a second abutting surface) and a second braking surface 902h (an example of a first abutting surface) of different stages. The outer ring 52f of the large-diameter disk outer plate 52b of the reel 52 shown in Fig. 19A abuts against the first braking surface 901h. Further, the inner ring 52g of the small-diameter disk inner plate 52c of the spool 52 abuts against the second braking surface 902h. The spool 52 is braked by the brake plate 900h, and the brake plate 900h sets the distance between the braking surface 902h and the inner wheel 52g of the disk inner plate 52c and the distance between the braking surface 901h and the outer wheel 52f of the disk outer plate 52b to be different.

Next, an example in which the reel 52 is provided in the reel setting mechanism 90B will be described. Fig. 19A is a perspective view showing an installation example of the spool 52. In the reel setting mechanism 90B shown in Fig. 19A, after the core 52a of the reel 52 is attached to the support rod 90a, the pressing lever 900b in the horizontal state shown in Fig. 18A is rotated by 90° to be set to a slightly vertical state. In order to move to the vertical state, the operating portion 90k is held by the user, and the pressing lever 900b is rotated in the vertical direction. At this time, the central circular portion 900i of the opening 900f is engaged with the rotating shaft 90d to rotate. The narrow groove-shaped portion in which the opening portion 900f is formed in two directions is engaged with a rectangular portion forming the rotation shaft 90d, and is a portion that cannot be rotated. The pressing lever 900b that rotates 90° in the vertical direction descends and the opening 900f slides. Further, in the pressing lever 900b, the U-shaped distal end portion 90g at the distal end thereof is fitted to the groove portion 90p of the support rod 90a and fixed.

The pressing lever 900b has a bent portion 900j formed by bending one end side to the outside. When the curved portion 900j rotates, the outer ring 52f of the disk outer plate 52b of the spool 52 is received. Thereby, the reel 52 is easily provided to the reel setting mechanism.

In the brake mechanism 89B shown in Fig. 19A and Fig. 19B, the energization is blocked. At this time, the movable iron core 890c of the solenoid 890a and the brake plate 900h are stretched to the solenoid main body side by the tension spring 890b, and the movable iron core 890c is contracted. Therefore, the braking surface 901h of the brake plate 900h is separated from the outer ring 52f of the disk outer plate 52b of the spool 52 by a distance L4. Further, the braking surface 902h of the brake plate 900h is separated from the inner ring 52g of the disk inner plate 52c of the spool 52 by a distance L5.

In this example, the distance L5 is set to be more frequent than the distance L4 (L5>L4). The brake plate 900h changes the timing (period) of the disk outer plate 52b and the disk inner plate 52c of the spool 52. That is, in the initial stage of use of the reel 52, in the brake plate 900h, the braking surface 901h abuts against the outer ring 52f of the disc outer plate 52b of the reel 52 to perform braking. In the later stage of use of the reel 52, when the outer wheel 52f of the disc outer plate 52b is worn, in the brake plate 900h, the braking surface 902h abuts against the inner wheel 52g of the disc inner plate 52c of the reel 52, and the inner wheel is mainly used. 52g is braked. Thereby, since the wear of the outer ring 52f and the inner ring 52g of the reel 52 can be suppressed, the life of the reel 52 can be extended.

Of course, on the contrary, the distance L4 is longer than the distance L5 (L5 < L4), the brake plate 900h abuts against the inner ring 52g, and then abuts against the outer ring 52f to perform braking. Further, the distance L5 is equal to the length of the distance L4 (L5 = L4), and the brake plate 900h can simultaneously abut against the outer ring 52f and the inner ring 52g of the spool 52 to perform braking.

The reel 52 shown in Figs. 19A and 19B is in a state of being released from braking. That is, the reel 52 is supported by the support rod 90a inserted into its core 52a. Then, the side of the disk outer panel 52b of the spool 52 cannot be pulled out by pressing the lever 900b, and the side of the disk inner panel 52c of the spool 52 cannot be pulled out by the side panel 900c.

In the brake release (energization interruption) state, the package 13 of the spool 52 is pulled out by the package conveyance mechanism 5A shown in Fig. 1 . By the package play mechanism 5A, the solenoid 890a is energized while the drawing of the packing 13 is completed. At this time, in the solenoid 890a, the movable iron core 890c is extended, and the brake plate 900h abuts against the outer ring 52f of the reel 52 or the inner ring 52g to perform braking. Thereby, after the packing 13 of the reel 52 is pulled out, the reel 52 does not rotate due to inertia, and the pull-out line of the packing 13 can be prevented from being slack.

Next, an operation example of the brake mechanism 89B will be described. Fig. 20A is a front view showing an operation example of the brake mechanism 89B in the initial stage of use of the spool 52. The brake mechanism 89B shown in Fig. 20A is in a state in which the solenoid 890a shown in Fig. 19B is energized. At this time, the movable iron core 890c of the solenoid 890a is pushed out and elongated. Thereby, the brake plate 900h is lowered, and the braking surface 901h abuts against the outer ring 52f of the disk outer plate 52b of the spool 52 to perform braking. Further, the braking surface 902h does not abut against the inner ring 52g of the disk inner plate 52c of the spool 52. At the time of the initial stage of use of the spool 52, the outer wheel 52f of the disk outer panel 52b does not wear. At this time, since the outer ring 52f of the disk outer plate 52b does not wear, the braking force of the brake mechanism 89B can be sufficiently exerted.

Fig. 20B is a front view showing an operation example of the brake mechanism 89B in the later stage of use of the spool 52. The packing 13 of the reel 52 shown in Fig. 20B is in a state of being somewhat consumed from the packing 13 of the reel 52 shown in Fig. 20B. At this time, the outer ring 52f of the disk outer plate 52b of the reel 52 shown in Fig. 20B is used for the braking operation due to the abutment on the braking surface 901h, and is somewhat worn.

As a result, the position at the time of energization of the brake plate 900h shown in FIG. 20B is lower than the position at the time of energization of the brake plate 900h shown in FIG. 20A due to the wear of the outer ring 52f of the disk outer plate 52b. Therefore, in the brake plate 900h, the braking surface 902h abuts against the inner ring 52g of the disk inner plate 52c of the spool 52, and the inner wheel 52g is mainly used for braking. Thereby, the life of the reel 52 can be extended. Further, even when the braking surface 902h abuts against the inner ring 52g of the disk inner plate 52c, the braking surface 901h abuts against the inner ring 52g of the disk outer plate 52b in the brake plate 900h, and exerts a certain braking effect.

21A is a perspective view showing a configuration example of the reel setting mechanism 90B and the brake mechanism 89C. Fig. 21B is a front view showing a configuration example of the reel setting mechanism 90B and the brake mechanism 89C. 21C is a side view of the reel setting mechanism 90B and the brake mechanism 89C. The reel setting mechanism 90B shown in FIGS. 21A to 21C includes a support lever 90a, a push lever 900b, a side panel 900c, and a rotation shaft 90d.

In the reel setting mechanism 90B, the pressing lever 900b is rotated at 90° to be set to a slightly horizontal state (reel setting standby state). A brake mechanism 89C is attached to a predetermined position of the side panel 900c. The brake mechanism 89C is an example of the second brake mechanism, and is in contact with the inner ring 52g of the disk inner plate 52c and the outer ring 52f of the disk outer plate 52b to control the spool 52. The brake mechanism 89C is composed of a solenoid 891a and brake plates 903h and 904h. The solenoid 891a is an example of a third telescopic operation member and is a push-type solenoid.

The solenoid 891a is provided in a slightly vertical direction with respect to the core 52a, and has a movable iron core (plunger) 891c that is controlled by the control unit 110 to perform energization or interrupting energization at a predetermined timing. In the solenoid 891a, the brake plates 903h and 904h are attached to the movable iron core 891c. For example, the brake plate 903h is an example of a third brake plate, and is slidably provided via a compression spring 892b (an example of an elastic member). Further, the brake plate 903h is stretched to the solenoid main body side by the tension spring 891b. The brake plate 904h is an example of the second brake plate and is fixed to the center of the movable iron core 891c. The brake plates 903h and 904h are slidably attached to the side panel 900c. The rotation of the spool 52 is braked by the brake plate 904h and the brake plate 903h.

In this example, the brake plates 903h and 904h have long holes 90s in the longitudinal direction at two positions, and the equal holes 90s are fitted into the arm 90u of the support solenoid 891a so as to be movable up and down. Further, the brake plates 903h and 904h are inserted at both side ends by the rail 90t. Thus, the brake plates 903h and 904h are slidably attached to the side panel 900c.

The brake plate 904h is fixed to the movable iron core 891c, and the brake plate 903h is engaged with the movable iron core 891c, and is biased to the solenoid main body side by the tension spring 891b. Thereby, the brake plates 903h and 904h move up and down in accordance with the movement of the movable iron core 891c. In particular, the brake plate 903h adjusts the braking force generated on the brake plate 903h side and the braking force generated on the brake plate 904h side by selecting the elastic force of the various compression springs 892b. With respect to the brake plate 904h, the load that is extended as the movable iron core 891c is directly transmitted, and the load that is extended with the movable iron core 891c on the brake plate 903h is transmitted via the compression spring 892b.

When the shape of the spool 52 is such that the length of the core 52a in the axial direction is long, and the winding amount of the packing 13 is increased, the following features (1) to (3) are obtained. (1) The braking force of the spool 52 acts on the disk outer plate 52b and the disk inner plate 52c of the spool 52. (2) The braking force of the reel 52 is directed from the disk outer plate 52b and the disk inner plate 52c to the core via the disk outer plate 52b and the disk inner plate 52c and the rear portion 52h of the core 52a (see FIG. 23C). 52a role. (3) Since the packing 13 is wound around the core 52a of the spool 52, the portion of the spool 52 that is large in inertia is the core 52a around which the packing 13 is wound. Due to the above features (1) to (3), both of the large-diameter disk outer plate 52b and the small-diameter disk inner plate 52c can be braked with good balance.

According to the brake mechanism 89C, the brake plate 904h is directly braked by the movable iron core 891c. On the other hand, the brake plate 903h is braked by the elastic force of the compression spring 892b that receives the pressing force of the movable iron core 891c. Thereby, by appropriately selecting the elastic force of the compression spring 892b, the average braking force acts on the disk outer plate 52b shown in Fig. 23C and the individual rear portion 52h of the disk inner plate 52c.

That is, the product of the pressing force F1 acting on the disk outer plate 52b shown in Fig. 23C and the distance L6 from the point of action of the pressing force F1 to the core 52a of the spool 52 and the pushing acting on the disk inner plate 52c. The pressure F2 coincides with the product of the distance L7 from the point of action of the pressing force F2 to the core 52a of the spool 52 (F1 × L6 = F2 × L7), and the braking force acts equally on the outer disk 52b and the inner disk of the disk Individual followers 52h of 52c. Thereby, excessive braking force can be prevented from acting on one side of the individual outer peripheral portion 52h of the disk outer plate 52b and the disk inner plate 52c.

The brake plate 903h has a braking surface 905h. The outer ring 52f of the large-diameter disk outer plate 52b of the reel 52 shown in Fig. 22A abuts on the braking surface 905h. Further, the brake plate 904h has a braking surface 906h. The inner ring 52g of the small-diameter disc inner plate 52c of the spool 52 abuts against the braking surface 906h.

Next, an example in which the reel 52 is provided in the reel setting mechanism 90B including the brake mechanism 89C will be described. The reel setting mechanism 90B shown in Fig. 22A is set to a vertical state after the support lever 90a is inserted into the core 52a of the reel 52, and the horizontal pressing lever 900b shown in Fig. 21A is rotated by 90°.

In the brake mechanism 89C shown in Figs. 22A and 22B, the energization is blocked. At this time, the movable iron core 891c of the solenoid 891a and the brake plate 903h are stretched to the solenoid main body by the tension spring 891b, and the movable iron core 891c is contracted. Therefore, the braking surface 905h of the brake plate 903h is separated from the outer ring 52f of the disk outer plate 52b of the spool 52. Further, the braking surface 906h of the brake plate 904h is isolated from the inner ring 52g of the disk inner plate 52c of the spool 52. In this example, the distance between the braking surface 905h and the outer ring 52f and the distance between the braking surface 906h and the inner wheel 52g are set to be equal.

The reel 52 shown in Figs. 22A and 22B is in a state of being released from braking. That is, in the spool 52, the core 52a is supported by being attached to the support rod 90a. Then, the side of the disk outer panel 52b of the spool 52 cannot be pulled out by pressing the lever 900b, and the side of the disk inner panel 52c of the spool 52 cannot be pulled out by the side panel 900c.

In the brake release (energization interruption) state, the package 13 of the spool 52 is pulled out from the package carrier transport mechanism 5A of Fig. 1. The solenoid 891a is energized while the packing 13 is being pulled out from the packing conveyance mechanism 5A. At this time, in the solenoid 891a, the movable iron core 891c is extended, the brake plate 903h abuts against the outer ring 52f of the spool 52, and the brake plate 904h abuts against the inner ring 52g of the spool 52 to perform braking. Thereby, after the packing 13 of the reel 52 is pulled out, the reel 52 does not rotate due to inertia, and the pull-out line of the packing 13 can be prevented from being slack.

Next, an operation example of the brake mechanism 89C will be described. Fig. 23A is a front view showing an operation example of the brake mechanism 89C in the initial stage of use of the spool 52. The brake mechanism 89C shown in Fig. 23A is in a state in which the solenoid 891a in Fig. 22B is energized. At this time, the movable iron core 891c of the solenoid 891a is pushed out and elongated. Thereby, the brake plates 904h and 903h are lowered. Then, the braking surface 906h abuts against the inner ring 52g of the disk inner plate 52c, and the braking surface 905h abuts against the outer wheel 52f of the disk outer plate 52b to perform braking.

Fig. 23B is a front view showing an operation example of the brake mechanism 89C in the later stage of use of the spool 52. The outer ring 52f of the disk outer plate 52b of the reel 52 shown in Fig. 23B is used for the braking operation by abutting against the braking surface 905h, and thus there is some wear. Similarly, the inner ring 52g of the disc inner panel 52c of the spool 52 also wears a little due to abutment against the braking surface 906h. Since the roughly average brake load acts on the outer ring 52f and the inner ring 52g, the outer wheel 52f and the inner wheel 52g generate an average wear.

Fig. 24A is a perspective view showing a configuration example of the reel setting mechanism 90B and the brake mechanism 89D. Fig. 24B is a front view of the reel setting mechanism 90B and the brake mechanism 89D. Fig. 24C is a side view of the reel setting mechanism 90B and the brake mechanism 89D. The reel setting mechanism 90B shown in FIGS. 24A to 24C is provided with a support lever 90a, a pressing lever 900b, a side panel 900c, and a rotating shaft 90d.

In the reel setting mechanism 90B, the pressing lever 900b is rotated by 90° to be set to a slightly horizontal state (reel setting standby state). A brake mechanism 89D is attached to a predetermined position of the side panel 900c. The brake mechanism 89D is an example of a second brake mechanism, and is constituted by solenoids 892a and 893a and a brake plate 907h. These solenoids 892a and 893a are push type solenoids. The solenoid 892a is an example of the fifth telescopic operation member, and is provided in a slightly vertical direction with respect to the core 52a, and the control unit 110 controls the energization or the interruption of the energization at a predetermined timing to expand and contract. In the solenoid 892a, the brake plate 907h is attached to the movable iron core (plunger) 892c.

For example, the brake plate 907h is an example of a fifth brake plate, and is attached to the solenoid main body side by the tension spring 893b, and the brake plate 907h is slidably attached to the side panel 900c.

Further, the solenoid 893a is an example of the fourth telescopic operation member, and is provided in the vertical direction with respect to the core 52a, and the control unit 110 controls the energization or the interruption of the energization at a predetermined timing to expand and contract. In the solenoid 893a, the brake plate 908h is attached to the movable iron core 893c. For example, the brake plate 908h is attached to the solenoid body side by the tension spring 894b. The brake plate 908h is an example of a fourth brake plate and is slidably attached to the side panel 900c. The rotation of the spool 52 is braked by the brake plate 908h and the brake plate 907h.

In this example, the brake plates 907h and 908h have long holes 90s in the longitudinal direction at two positions, and the equal holes 90s are fitted to the arms 90u of the support solenoids 892a and 893a so as to be movable up and down. Further, the brake plates 907h and 908h are inserted into the both ends by the rail. The brake plates 907h and 908h are slidably mounted to the side panel 900c.

In this manner, the brake plate 907h moves up and down corresponding to the movable iron core 892c. Further, the brake plate 908h moves up and down in accordance with the operation of the movable iron core 892c.

At the initial stage of use of the spool 52, the packing device 13 is wound in a large amount. Therefore, with the packing action, the inertia of the reel 52 is increased as the packing 13 is pulled out. Therefore, the required braking force of the reel 52 also becomes large. Thereby, both the solenoids 892a and 893a are actuated to control the spool 52 at the initial stage of use of the spool 52.

Further, in the later stage of use in which the packing 13 of the reel 52 is consumed, the inertia at the time of rotation of the reel 52 caused by the pulling out of the packing 13 is smaller than the initial stage of use of the reel 52. For example, when the remaining amount of the packing device 13 is about half, only one of the solenoid 892a or the solenoid 893a (for example, the solenoid 892a) is actuated to brake the spool 52.

Further, in the final stage of use of the packing 13 consumed by the reel 2, the inertia at the time of the rotation of the reel 52 caused by the pulling out of the packing 13 is small as compared with the later stage of use of the reel 52. For example, when the remaining amount of the packing implement 13 is about 1/4, for example, only the solenoid 893a is actuated to brake the spool 52. That is, the solenoid 892a and the solenoid 893a are alternately used in consideration of the wear of the braking portion (the outer ring 52f, the inner wheel 52g) of the spool 52.

The brake plate 907h has a braking surface 909h. The outer ring 52f of the large-diameter disk outer plate 52b of the reel 52 shown in Fig. 25A is bottomed on the braking surface 909h. Further, the brake plate 908h is provided with a braking surface 910h. The inner ring 52g of the small-diameter disc inner plate 52c of the spool 52 abuts against the braking surface 90h.

Next, an example in which the reel 52 is provided in the reel setting mechanism 90B including the brake mechanism 89D will be described. Fig. 25A is a perspective view showing an example of installation of the spool 52. In the reel setting mechanism 90B shown in Fig. 25A, the core 52a of the reel 52 is attached to the support rod 90a, and the horizontal pressing lever 900b shown in Fig. 24A is rotated by 90° to be set to a slightly vertical state.

The energization of the brake mechanism 89D shown in Figs. 25A and 25B is blocked. At this time, the movable iron core 892c and the brake plate 907h of the solenoid 892a on one side extend to the main body side by the tension spring 893b, and the movable iron core 892c contracts. Therefore, the braking surface 909h of the brake plate 907h is separated from the outer ring 52f of the disk outer plate 52b of the spool 52. Further, the movable iron core 893c and the brake plate 908h of the other solenoid 893a are stretched to the solenoid main body side by the tension spring 894b, and the movable iron core 893c is contracted. Therefore, the braking surface 910h of the brake plate 908h is separated from the inner ring 52g of the disk inner plate 52c of the spool 52.

The reel 52 shown in Figs. 25A and 25B is in a state of being released from braking. That is, in the reel 52, the core 52a is attached to the support rod 90a to be supported. Then, the side of the disk outer panel 52b of the spool 52 is not pulled out by pressing the lever 900b, and the side of the disk inner panel 52c of the spool 52 cannot be pulled out by the side panel 900c.

In the state where the brake is released (discharged), the package 13 of the spool 52 is pulled out from the packer transport mechanism 5A shown in Fig. 1 . The package 13 is energized from the end of the package transport mechanism 5A, and both of the solenoids 892a and 893a or one of the solenoids 892a and 893a are energized. When the solenoid 892a is energized, the movable iron core 892c is extended and the brake plate 907h abuts against the outer ring 52f of the spool 52 to perform braking. Further, when the solenoid 893a is energized, the movable iron core 893c is extended, and the brake plate 908h abuts against the inner ring 52g of the spool 52 to perform braking. Thereby, after the packing device 13 is pulled out, the reel 52 does not rotate due to inertia, so that the pulling of the packing device 13 can be prevented from being slack.

Next, an operation example of the brake mechanism 89D will be described. Fig. 26A is a front view showing an operation example of the brake mechanism 89D in the stage after the use of the spool 52. The brake mechanism 89D shown in Fig. 26A is in a state in which only the solenoid 892a shown in Fig. 25B is energized. At this time, the movable iron core 892c of the solenoid 892a is pushed out and elongated. Thereby, the brake plate 907h is lowered. Then, the braking surface 909h abuts against the outer ring 52f of the disk outer plate 52b to be braked.

Fig. 26B is a front view showing an operation example of the brake mechanism 89D in the final stage of use of the spool 52. The packing device 13 of the reel 52 shown in Fig. 26B is in a state in which the packing device 13 of the reel 52 shown in Fig. 26A is consumed to some extent. At this time, the outer ring 52f of the disk outer plate 52b of the reel 52 shown in Fig. 26B is used for the braking operation by abutting against the braking surface 909h, so that some wear occurs. Therefore, the inner wheel 52g of the disk inner plate 52c of the spool 52 is used for braking. For example, only the solenoid 893a is energized. At this time, the movable iron core 893c of the solenoid 893a is pushed out and elongated. Thereby, the brake plate 908h is lowered. Then, the braking surface 910h abuts against the inner ring 52g of the disk inner plate 52c to perform braking. Further, at the initial stage of use of the spool 52, both of the solenoids 892a and 893a are actuated to brake the spool 52. Thereby, the life of the reel 52 can be extended. Moreover, the average wear of the inner ring 52g and the outer ring 52f can be achieved.

Thus, the baler 100 according to the present invention is provided with a reel 52 having a disc outer panel 52b which is larger than the disc inner panel 52c, and the brake mechanisms 89B to 89D are simultaneously or alternately abutted against the disc inner panel. The inner wheel 52g of 52c or the outer wheel 52f of the outer disk 52b is braked.

Therefore, the timing of the disk outer plate 52b and the disk inner plate 52c which are slidably attached to the spool 52 are adjusted. Further, since both the disk outer plate 52b and the disk inner plate 52c are used, the portion where the braking operation can be generated is increased. Thereby, the braking force can be improved as compared with the method of braking by sliding the outer peripheral portion of the conventional one-piece guide. However, the abrasion of the spool 52 can be suppressed, and the generation of the abrasion powder and the deformation of the spool 52 can be suppressed.

Moreover, the present invention is applicable to the brake device of the winding device in addition to the baler 100. In this case, for example, the configuration of the reel setting mechanism 90A, the brake mechanism 89A, the reel 52, the packing conveyance mechanism 5A, and the control unit 110 is realized. The brake device of the winding device is not limited to a packing device, and a decorative tape or a binding tape or the like can be applied to fields other than the packaging process.

Next, a configuration example and an operation example of the label transport mechanism 4A will be described with reference to FIGS. 27 and 28. 27A and 27B are perspective views showing a structural example of the label transport mechanism 4A. The label transport mechanism 4A shown in FIG. 27A includes a cassette 40 and a label transport unit 41. The cassette 40 is an example of a label storage unit. In the cassette 40, the label 1A is stored in a plurality of sheets in a stacked state. The cassette 40 is inserted obliquely from the rear end side of the label transport unit 41 and attached to the label transport unit 41.

The label transport unit 41 includes a label transport roller 41a and a label transport motor 41b. In this example, the label transport roller 41a is driven by the roller rotating shaft 41d, and the two roller rings 41e are pressed into the roller rotating shaft 41d and fixed at intervals. A gear 41c is attached to one end of the roller rotating shaft 41d. The material of the roller ring 41e is, for example, a rubber element. Of course, as long as it is a material having a large friction with the label 1A, materials other than rubber may be used.

The label transport roller 41a is vertically rotatably attached to the roller rotating shaft 41d in the feeding direction of the label 1A received by the cassette 40 in front of the bottom surface of the label transport unit 41. At this time, the roller ring 41e pressed into the roller rotating shaft 41d abuts against the label 1A at the lowermost portion of the cassette 40.

A label transport motor 41b is attached to the side surface of the label transport unit 41. The gear 41c of the label transport roller 41a is engaged with the label transport motor 41b. According to this configuration, the label transport roller 41a is rotated by the rotation of the label transport motor 41b, and the label 1A received at the lowermost portion of the cassette 40 is fed out one by one. Moreover, the label transport motor 41b can be, for example, a stepping motor.

Further, the label transport unit 41 is provided with a label transport guide 42. The label transport guide 42 has a function as an example of a guide portion, and guides the label 1A sent from the label transport portion 41. The label transport guide 42 includes left and right guides 42a, an actuating pin 42b, and a rotating shaft 42d. The left and right guide plates 42a are an example of the first and second window members, and are openably and closably attached.

In this example, the guide 42a has a curved shape of an arc extending to the outside. The curved guide 42a has links 42e, 42f. The link 42e is provided on the upper wall surface of the guide 42a, and the link 42f has a predetermined angle at one end of the link 42e. The rotating shaft 42d is attached to a joint portion of the link 42e and the link 42f.

Further, an actuating pin 42b is attached to the distal end of the link 42f. Further, a pin 42g for a tension spring is attached to the link 42e, and a tension spring 42h is attached to the pin 42g (see Fig. 28B). The tension spring is stretched toward the link 42e of the right and left guide plates 42a. The guide 42a shown in Fig. 27 is in a closed state. In this state, the guide 42a guides the label 1A conveyed by the label transport unit 41 along the curved shape forming the label transport path I.

The guide 42a shown in Fig. 27B is in an open state. In order to open the guide 42a, the actuating pin 42b is pushed out in the direction of the arrow Q3 shown in Fig. 27B (in the same direction as the arrow Q3 shown in Fig. 7). When the movable pin 42b is pushed out in the direction of the arrow Q3, the left and right guide plates 42a are separated by the rotation shaft 42d as an axis. At this time, the left and right guide plates 42a are approached by the stretching of the tension spring 42h. Therefore, when the actuation pin 42b urged in the direction of the arrow Q3 is released, the left and right guides 42a are brought closer by the force of the tension spring 42h, and return to the closed state shown in Fig. 27A. Thus, the left and right guide plates 42a are opened and closed.

FIGS. 28A and 28B are perspective views showing a transport example of the label transport mechanism 4A transporting the label 1A. The label transport mechanism 4A shown in Fig. 28A arranges the curl guide 30 on the label 1A which is made of the guide 42a of the label transporting plate 42 of the label transport mechanism 4A shown in Fig. 27B. The mounting portion 11A is guided in a slightly vertical direction.

In this example, the mounting portion 11A of the label 1A is guided between the label supporting member 30e that is attached to the front of the curling guide 30 and the label hanging portion 30b of the curling guide 30. In other words, the concave portion 12m provided below the attachment portion 11A of the label 1A is disposed on the front surface of the label hanging claw portion 30b of the curl guide 30.

In a state where the concave portion 12m of the label 1A is disposed on the front surface of the label hanging claw portion 30b of the curling guide 30, as shown in Fig. 28, the curling guide 30 slides (advances). Thereby, the concave portion 12m of the label 1A is hung from the label hanging claw portion 30b of the curl guide 30, and the mounting portion 11A of the label 1A is connected to the label supporting member 30e. Further, by the advancement of the curling guide 30, the operating pin 42b that has fallen into the recess 30a of the curling guide 30 is pushed up while being pushed up, and the left and right guides 42a are rotated to open. Thereby, the label 1A held by the curl guide 30 passes through the opening of the left and right guides 42a. In this manner, the label 1A guided by the guide 42a of the label transporting guide 42 is carried.

Fig. 29 is a perspective view showing a configuration example of the curl guide 30 in the label holding mechanism 3A. The label holding mechanism 3A shown in Fig. 29 has a curl guide 30.

The curling guide 30 has a block-shaped main body portion 301 which is formed in a T shape, and a pair of label hanging claw portions 30b which function as claw portions are provided on the lower surface of the front surface of the main body portion 301, so that the mounting portion 11A formed on the label 1A is hooked. live. The mounting portion 11A forms an alignment portion of the tag 1A.

At the same time, the curling guide 30 has a curved guiding protrusion 30c on the front surface of the body portion 301, and a groove-shaped packing path 303 is provided in the curved guiding protrusion 30c. A cover-like projection 30d is provided on the upper surface of the front surface of the curl guide 30, and the attachment portion 11A of the label 1A is fitted between the label hanging claw portion 30b and the upper cover-like projection portion 30d. The wrapping guide passage 303 is self-aligned with the engaging hole 11m of the label 1A by the curl guide 30. The packing 13 is passed from the engaging hole 11m on one side to the engaging hole 11m on the other side. The front side of the packing path 303 is opened.

A label supporting member 30e constituting the label supporting mechanism 2A is provided at a predetermined position from the upper portion of the curl guide 30 to the packing path 303, and the upper end of the label 1A is supported during label transportation. A metal or resin member processed into an L-shape is used on the label supporting member 30e using the member body. In this example, a recess 304 for mounting the label supporting member 30e is provided on the upper end of the front end of the curl guide 30, and the label supporting member 30e is attached to the recess 304 and fixed by the pin 302. The L-shaped portion of the label supporting member 30e is attached in a posture toward the label entering direction. This is to prevent the label 1A from rotating at the front end of the L-shaped portion of the label supporting member 30e.

Fig. 30 is a side view showing a configuration example of the curl guide 30 when the label supporting member 30 is mounted.

According to the curl guide 30 shown in Fig. 30, in the label supporting member 30e, the angle at which the member body forms the L-shape is θ, and when the margin angle is α, the angle θ is set to θ = 90° + α. The reproducibility of the label 1A is favorably supported by the curl guide 30. The margin angle α is used to easily pull the packaged label 1A out of the curl guide 30. The margin angle α is set to, for example, 5° to 45°.

31 and 32 are perspective views of a comparative example of the label supporting member 30e in the curl guide 30.

The curl guide 30 shown in Fig. 31 is a case where the label supporting member 30e (having the label supporting member 30e) is attached. At this time, the pair of label hanging claw portions 30b and the label supporting member 30e hold the label 1A at three points. As described above, when the label supporting mechanism 2A is configured, the blocking label 1A is rotated about the label hanging claw portion 30b.

On the other hand, the curl guide 30 shown in Fig. 32 is a case where the label supporting member 30e (the label-free supporting member 30e) is removed. That is, the small screw 302 of the upper portion of the curling member 30 shown in Fig. 31 is loosened and removed, and the label supporting member 30e is detached from the concave portion 304. At this time, it is determined that the label 1A is not easily rotated and dropped around the label hanging claw portion 30b.

In the case where the label 1A is conveyed to one side of the guide plate 95 by the curl guide 30, the claw portion 30b of the curl guide 30 is hung from the concave portion 12m (notch portion) of the inclined shape of the label 1A shown in Fig. 2 . When the rear end portion of the label 1A is conveyed by the label transport roller 41a of the label transport unit 41 shown in Fig. 27, the curl guide 30 is pulled out. Therefore, the label 1A is tilted. As a result, the label 1A rotates around the pair of label hanging claws 30b of the curling guide 30, which causes the label 1A to fall off from the curling guide 30.

In this example, in order to prevent this, the label supporting member 30e is attached downward to the label supporting member 30e mounting recess 304 in an L-shaped portion, and the label supporting member 30e mounting recess 304 is attached to the upper end of the curling guide 30. .

Thus, according to the baler 100, the strip-shaped cut-away packing 13' is wound around the fold of the bag 14 using the two engaging holes 11m, 11m provided in the label 1A, when the label 1A is attached to the bag 14 At the time of folding, the label support member 30e is provided on the upper end of the front end of the curl guide 30, and can be hung on the upper portion of the label.

Therefore, the label 1A can be prevented from rotating around the label hanging claw portion 30b. Thereby, it is possible to prevent the label from coming off due to the rotation as compared with the case where the label supporting member 30e is not attached. Moreover, the packaging tool 13 inserted from the engaging hole 11m of the one side label 1A is excellent in reproducibility from the other engaging hole 11m. Therefore, the label 1A is smoothly pulled out from the packaged label transport mechanism 4A, and a highly reliable baler 100 can be provided.

Fig. 33 is a perspective view showing a mounting example of the label supporting member 42c in the label transporting mechanism 4A as seen from below. In this example, the label supporting member 42c is provided on the downstream side of the label carrying roller 41a to support the rear end portion of the label.

The label transport mechanism 4A shown in Fig. 33 is an element having a label support function and transporting the label 1A toward the label holding mechanism 3A. For example, the label transport mechanism 4A has the label transport path I and the transport roller 41a, and the label 1A is transported to the label holding mechanism 3A via the label transport path I.

A label supporting member 42c constituting another label supporting mechanism 2A is provided on the label transport mechanism 4A, and the rear end portion of the label 1A is held. For example, the label supporting member 42c is disposed from a lower portion of the guide 42a of the label transport mechanism 4A to a portion of the label transport path I. In this example, the label supporting member 42c is disposed from the position of the outer side of the transport roller 41a to the position of the label transport path I.

A metal or resin member that processes the body member into a tongue shape is used on the label supporting member 42c. For example, using a bent member, the elongated bent sheet having a predetermined thickness is folded into a right-angled mountain shape to define a first curved portion 401 on the member body, and a portion extending from the portion has a circular shape and is folded into a valley shape. The second bent portion 402. Thereby, the curl guide 30 reaches the guide 95 and supports the rear end portion of the label 1A.

Figs. 34 and 35 are structural transition diagrams of the functional examples (the first and second) of the label transport mechanism 4A and the label support mechanism 3A. Fig. 36 is a perspective view showing an example of supplementing the label 1A of another size.

Fig. 34A is a side view showing the broken portion of the guide portion of the standby example of the home position HP of the curl guide 30. In Fig. 34A, the starting position HP of the curling guide 30, the guide 42a of the label transporting mechanism 4A is in a closed state, and the curling guide 30 is separated from the guide 95 and moved to the leftmost side, that is, in the state of The upper extension line of the guide 42a in a state where the front end portion of the curl guide 30 is closed is referred to as a standby position.

Fig. 34B is a broken side view showing a part of the guide of the label loading example in the home position HP of the curl guide 30. According to the label transport mechanism 4A shown in Fig. 34B, the curl guide 30 is in the standby state at the home position HP, and the label 1A is loaded. At this time, the front end portion of the label 1A is supported by the label supporting member 30e of the curl guide 30.

In this example, the label 1A of the cassette 40 accommodated in the label transport mechanism 4A is sent out from the label transport roller 41a. In the label 1A sent by the label transport roller 41a, the curl guide 30 is actuated to slide (advance) the concave portion 12m of the label 1A shown in Fig. 2 and to hang the label hanging claw 30b at the front end portion of the curl guide 30.

At this time, the label 1A is completely fed from the cassette 40 by the label transport roller 41a, and the rear end portion of the information presenting portion 10A of the label 1A is supported by the label supporting member 42c. By the label supporting member 42c, the falling of the label 1A when the curl guide 30 advances is prevented.

Fig. 35A is a side view showing an example in which the label is transported from the initial position HP of the curl guide 30 to the guide 95 of the package contracting mechanism 7A. According to the transport mechanism 4A shown in Fig. 35, while the guide 42a is opened, the curl guide 30 of the label holding mechanism 3A starts moving to the right side, moving the label 1A toward the guide 95 of the packing and contracting mechanism 7A (guide ). At this time, after the label 1A is removed from the label transport roller 41a, the label 1A is supported by the label supporting member 42c. In Fig. 35A, II is the moving direction of the curl guide 30. According to the label supporting mechanism 3A shown in Fig. 35B, the curling guide 30 comes into a state of abutting (arriving) on the guide 95. At this time, the front end portion of the label 1A is supported by the label holding member 30e of the curl guide 30 and the guide 95, and the rear end portion of the label 1A is obliquely supported by the label supporting member 42c of the label transport mechanism 4A. From this arrival time point, the label 1A is held by the label hanging claw 30b of the curl guide 30 abutting on the leading end of the guide mechanism 8A and the guide mechanism 8A.

Thereby, the falling of the label 1A can be prevented. Thereafter, in a state in which the label 1A is held by the label hanging claw portion 30b of the curl guide 30 and the guide mechanism 8A, the packing device 13 is conveyed toward the label 1A by the packing device conveying mechanism 5A shown in Fig. 1 .

Thus, by holding the label 1A obliquely, the label 1A is pulled out from the label transport mechanism 4A without the label 1A being detached by the curl guide 30. Therefore, the front end portion of the label 1A is prevented from being detached from the curl guide 30 by the label holding member 30e of the curl guide 30 and the guide 95.

Further, Fig. 36 is a perspective view showing a transport example of the supplementary long label 1A'. The curl guide 30 moves in the moving direction II shown in Fig. 36. According to the label holding mechanism 3A shown in Fig. 36, the length of the long label 1A' is longer than the length (normal length) of the label 1A shown in Fig. 33. At this time, since the label support member 42c of the label transport mechanism 4A supports the rear end portion of the long label 1A', the long label 1A' longer than the general length shown in Fig. 33 is completely transported from the label at the long label 1A'. The reverse movement when the roller 41a is disengaged can be suppressed by the label supporting member 42c, and the falling of the long label 1A' can be prevented.

As described above, according to the baler 100, when the label transport mechanism 4A has the label support member 42c, and the label 1A is transferred from the label transport mechanism 4A to the label support mechanism 3A, the label support member 42c delays the rear end opening period of the label 1A.

Therefore, as shown in Fig. 36, even when the long label 1A' longer than the normal length is operated, it is possible to prevent the label from being missed and falling off as compared with the case where the label supporting member 42c is not attached. Thereby, when the length of the label 1A becomes long or becomes short, the label 1A is reproducible from the label transport mechanism 4A to the label support mechanism 3A, and the baler 100 of high reliability is provided. As a result, the label 1A is conveyed from the label support mechanism 3A with good reproducibility to the package contracting mechanism 7A.

Fig. 37 is a top view showing an example of the appearance of the baler 100. In this example, a space area (bag packing groove) for guiding from the packing opening 103 of the baler 100 to the mounting space portion 92b is provided, and the packaging failure caused by the excess of the bag 14 can be prevented. The baler 100 shown in Fig. 37 has an intermediate chassis portion 92a above the body chassis portion 92, a substrate 92i for mounting the package forming mechanism, and an upper panel 19.

In this example, the packing opening 103 is set in the lower portion near the center of the upper panel 19, and the edge portion 901 for bag introduction is provided in the upper panel 19. The edge portion 901 and the front end inclined portion 903 of the guide 95 of the guide mechanism 9A form a triangular space region. The space area of the triangle is designed to be inserted into the apex of the triangle when the bag is installed. Thereby, the guide plate 95 is actuated as a shutter to perform a bag mounting process.

Further, one end of the edge portion 901 shown in Fig. 37 is connected to the R-shaped bag introduction portion 902 provided in the intermediate chassis 92a, and the other end of the edge portion 901 forms an installation space of the intermediate chassis 92a connected to the guide plate 8A. The front end portion of the portion 92b (see Fig. 38).

Fig. 38 is a top view showing the internal structure of the baler 100. 39A and 39B are perspective views of a configuration example of the guide 95 and a mounting example thereof as viewed from the back side. The baler 100 shown in Fig. 38 is in a state in which the upper panel 19 is detached from the intermediate chassis portion 92a, and has a packing device contracting mechanism 7A, a movable guide mechanism 8A, and a label holding drive mechanism 9A.

The packing device contracting mechanism 7A is provided in the intermediate chassis 92a, and is attached to the bag 14 by the packing tool 13 of the packing device path 303 of the label holding mechanism 3A. The packing device contracting mechanism 7A has a U-shaped mounting space 92b for inserting the object to be mounted. The installation space portion 92b is provided on the bag mounting side with the intermediate chassis 92a. The wrapping device 7A is provided with a torsion arm 70 constituting an example of a rotating shaft, and is twisted by the cutting tool 13' after the cutting of the two engaging holes 11m of the tag 1A (see Fig. 40).

Below the packing device contracting mechanism 7A, the guide mechanism 8A shown in Fig. 39A is attached to the intermediate chassis portion 92a, and the tag 1A and the bag 14 are guided to the mounting space portion 92b to operate. In this example, a pair of rail members 92g and 92b are disposed on the surface of the intermediate chassis portion 92a, and an example of the guide members is formed. The U-shaped guide plates 95 shown in Fig. 39 can be used arbitrarily in combination ( Refer to Figure 40).

The guide plates 95 are often biased to the sides of the label holding mechanism 3A. The guide plate 95 has a plate main body portion 95a shown in Fig. 39B, and is formed of a sheet metal member such as an iron plate. The plate main body portion 95a is provided with a notch portion 95b for guiding the bag notch, an opening portion 95c, an opening portion 95d, and a projection portion 95e for spring attachment.

The notch portion 95b has an opening width W (W≧w) equal to or larger than the width w of the mounting space portion 92b. The opening width W smoothly guides the fold of the bag 14 from the packing opening 103 toward the mounting space portion 92b. The notch portion 95b has an operation of extending the length of the U-shaped inside of the mounting space portion 92b. In this example, when the bag is attached, the length of the notch portion 95b protruding from the front end portion of the mounting space portion 92b is added to the inner length of the U-shape, thereby securing the insertion from the bag (the triangular region shown in Fig. 37). The length to the mounting space portion 92b (near the vertex) is sufficient.

The opening 95c is a rectangular hole for detaching the torsion arm 70. The opening portion 95d is a rectangular hole portion for locking the guide plate 95. When the opening portion 95d is formed in the plate main portion 95a, the projection portion 95e cuts in a necessary portion of the plate main portion 95a. This portion is a bent component and has hole portions 904 and 905 for spring mounting. An inductor mark projecting portion 95f is provided at a rear end portion of the plate main body portion 95a, and a protruding portion 95g for positional restriction is provided at the front end portion.

In addition, the plate main body portion 95a is provided with a pair of long holes 906 for separating the elements, a long hole 907, a long hole 908 for position restriction, and the like. In this example, the long hole 906 is an opening portion in which the base member 92i to which the package forming mechanism is attached is fixed to the base members (not shown) of the pins 92e and 92f. The long hole 907 is an opening that intersects the sector gears 97a and 97b. The long hole 908 is an opening that connects the shaft portions of the gears 96a and 96b.

On the other hand, the intermediate chassis portion 92a is provided with two opening portions 92c and openings 92d which are linearly arranged with the mounting space portion 92b as shown in Fig. 39. The opening 92c is a hole for detaching the torsion arm 70, the opening 92d is a hole for restricting movement of the guide 95, and the back surface of the intermediate chassis 92a is provided with a pin 92e and a pin 92f on both sides of the opening 92c. . The pin 92e and the pin 92f are composed of a metal rod. A ring groove (not shown) for fixing and fixing is provided at the end of the pin 92e and the pin 92f.

In this example, as shown in Fig. 39A, in the state in which the projection 95e is fitted into the opening 92d, the hole 904 of the projection 95e and the pin 92e are coupled by the spring 82a, and the projection 95e is The hole portion 905 and the pin 92f are coupled by a spring 82b. Thereby, the guide mechanism 8A is obtained. As described above, when the guide mechanism 8A is configured, the label 1A is conveyed to the folded position of the bag 14 inserted into the installation space portion 92b while the curl guide 30 and the guide 95 hold the label 1A.

In addition to the guide mechanism 8A, the intermediate chassis portion 90a has a label holding drive mechanism 9A that moves in a direction in which the label holding mechanism 3A approaches or moves away from the guide mechanism 8A, and the label holding mechanism 3A abuts The guide mechanism 8A is pushed back and driven.

The lock mechanism 81 is provided in the above-described guide mechanism 8A (see FIG. 40A). The lock mechanism 81 shown in Fig. 40A includes a half-moon flange shape (hereinafter referred to as a half moon shape) provided on the torsion arm 70 of the package attachment mechanism 7A, and a guide plate 95 provided on the guide mechanism 8A. The opening portion 95d for the engagement. In this example, the half moon portion is suspended from the opening portion 95d in accordance with the rotational position of the cam plate 99.

For example, when the half moon-shaped portion is located at the position of the lower chord shape with respect to the opening portion 95d, the half moon-shaped portion is not suspended from the opening portion 95d. The positional relationship becomes a state in which the guide plate 95 is not locked. On the other hand, when the guide plate 99 is rotated by 180° and the half moon-shaped portion is moved to a position that is in the upper chord shape with respect to the opening 95d, the half moon-shaped portion is suspended from the opening 95d. The positional relationship becomes the state of the lock guide 95.

Thus, when the guide mechanism 8A is constructed, the guide plate 95 is locked by the cam plate 99, and the guide 95 can be prevented from flying out after being packaged. Thereafter, the lock is released by the rotation of the cam plate 99.

In this example, the guide evaluator 107 for the guide which is an example of the detecting device is attached to a predetermined position on the back surface of the substrate 92i for packaging the traveling mechanism shown in Fig. 38. For example, the guide sensor 107 is disposed at a position where the protrusion 95f for the sensor mark of the guide 95 shown in FIG. 39A passes through the slit of the guide sensor 107 (refer to FIG. 40).

A penetrating optical sensor is used on the guide sensor 107. The guide sensor 107 senses the position of the opening 95d of the guide 95 of the half-moon cam plate 99 of the packing and contracting mechanism 7A to output position information. When such a position sensor 107 is provided, since the position of the guide plate 95 is grasped by the control portion 11 that forms the function of the control device, the guide plate delay recovery function can be controlled.

For example, when the opening 95d of the guide 95 is located in front of the half-moon cam plate 99 of the package attachment mechanism 7A, the guide 95 is biased by a spring or the like to fly out in the direction of the label holding mechanism 3A. When the opening portion 95d of the guide 95 is located at the same position of the cam plate 99 of the packing and contracting mechanism 7A, the guide 95 is pressed into the label holding mechanism 3A, stronger than the biasing force of the spring or the like, and pulled into the guide mechanism 8A. The state of the side. Thereby, it is confirmed by the position of the guide plate 95 whether the notch of the bag 14 is appropriately provided in the installation space portion 92b.

The baler 100 shown in Fig. 38 includes a control unit 110, which is engaged with the packaged device 13' after twisting the two engaging holes 11m of the label 1A by the packing mechanism 7A. 1/2 rotation to twist the cut package 13' to form the label 1A, and the remaining 1/2 rotation causes the cam 99 of the package attachment mechanism 7A to engage with the opening 95d of the guide 95 to control the package. Agency 7A. For example, the number of times is set to 2.5 times, 3.5 times, and 4.5 times in an integer number, and the motor is turned ON by an integer number of times, and is turned OFF by 0.5 times. When such a control unit 110 is provided, the function of delaying the return of the guide can be realized.

Here, the guide plate delay recovery function is such that the operation of the guide plate 95 is locked even after the packaging process for the bag 14 is completed, and the state is stopped in the next step without moving to the next step, and the unlocking by the control unit 110 is released. In the case where the guide 95 does not have this function, the action of delaying the reply is performed.

This guide delay return function is such that the distance that the packaged bag 14 is pulled out from the installation space 92b to the outside becomes short, and the bag 14 is easily taken out from the installation space portion 92b to the outside. Thus, the guide plate 95 can be locked by the cam plate 99, and the flying out of the guide plate 95 after the packing can be prevented. Thereafter, the lock is released by the rotation of the cam plate 99.

Next, a description will be given of a function example of the label holding mechanism 3A and the guide mechanism 8A. Fig. 40 to Fig. 42 are top views of functional examples (one to three) of the label holding mechanism 3A and the guide mechanism 8A. 40A is a top view showing an example of the positional relationship of the label holding mechanism 3A and the guide mechanism 8A during standby.

According to the positional relationship of the label holding mechanism 3A and the guide mechanism 8A shown in FIG. 40A, the front end portion of the guide plate 30 and the front end portion of the guide plate 95 are set (predetermined) by a distance L1, and the guide 95 is provided. The rear end portion of the position restricting portion 95g and the front end portion of the rail member 92h are set (predetermined) by a distance L2. This separation distance L2 is generated by the deflection of the guide plates 95 by the springs 82a, 82b shown in Fig. 39A.

In this configuration, when the guide plate 95 is pushed to the right side, it comes into a state of abutting against the front end portion of the rail member 92h and retreating. That is, the guide plate 95 is often biased to the front side by the springs 82a and 82b, and is pushed and pulled. In the standby state of the label holding mechanism 3A and the guide mechanism 8A, the label 1A is held by the label hanging claw portion 30b of the guide 30. At this time, the protrusion portion 95f for the sensor mark is output to the control portion 110 by, for example, a position detection data D6 of a high level (hereinafter referred to as "H" level) because the slit of the guide plate sensor 107 is not traversed. .

When the standby position of the package attachment mechanism 7A is a position where the half moon-shaped portion of the cam plate has a lower chord shape with respect to the opening 95d, the half moon-shaped portion is not suspended from the opening 95d. This standby position becomes the state of the lock guide 95.

Fig. 40B is a top view showing an example of the positional relationship when the label holding mechanism 3A comes into contact with the guide plate mechanism 8A. According to the positional relationship example of Fig. 40B, the label holding drive mechanism 9A moves the curling guide 30 shown in Fig. 40A from the standby state to the previous stage, and moves the state separated by the distance L1. In the previous movement, the front end portion of the curl guide 30 is in a state of abutting against the front end portion of the guide plate 95 via the label 1A. In other words, the state in which the guide plate 95 and the curl guide 30 sandwich the label 1A can prevent the label 1A from coming off. Thereafter, in this state, the label 1A moves toward the mounting space portion 92b.

Moreover, at the abutment time point, there is no change in the distance L2. The guide plate 95 is biased by the springs 82a, 82b shown in Fig. 39A. Further, since the guide sensor 107 is also transversely cut by the protruding portion 95f, the position "" of the "H" position is output". The position detection data D6 of the "H" level indicates that the guide 95 is in a free state.

Fig. 41A is a top view showing an example of the positional relationship when the label holding mechanism 3A is pressed into the guide plate mechanism 8A. According to the positional relationship example of Fig. 41A, the label holding drive mechanism 9A performs the late movement of the curling guide 30 from the position shown in Fig. 40B, and is in a state of being separated by the distance L2. In this example, the guide 95 is pushed by the label hanging claw portion 30b. In this late movement, the front end portion of the guide 30 abuts against the front end portion of the guide 95, and the rear end portion of the protruding portion 95g of the guide 95 abuts against the front end portion of the rail member 92h. At this point of time, the conveyance of the label 1A toward the installation space portion 92b is completed.

At this time, the protruding portion 95f for the sensor mark is shielded from light by the slit that crosses the guide plate sensor 107, and for example, the position detection data D6 of the low level (hereinafter referred to as "L" level) is output to the control. Part 110. Thereafter, the control unit 110 activates the label holding drive mechanism 9A by the position detection data D6, and the packaged packaging device 13A is formed by the packaging device forming mechanism 6A, and the torsion arm 70 of the packaging device contracting mechanism 7A is cut off. Packing 13' bundled label 13'.

41B is a top view showing an example of the positional relationship of the cam plate 99 of the guide mechanism 8A at the end of packaging in the baler 100. At the same time as the completion of the processing, in the 41B, the control unit 110 operates the lock mechanism 81. For example, in the lock mechanism 81, the half-moon cam plate 99 provided in the torsion arm 70 of the package attachment mechanism 7A is stopped from the standby state at a position rotated by 180°.

By this rotation, the cam plate 99 is stopped at a position where it is engaged with the opening portion 95d for engaging the cam of the guide 95. In other words, the half moon portion of the cam plate 99 stops in a posture in which the opening portion 95d is in a shape of a winding, and the cam plate 99 is engaged with the opening portion 95d to lock the biasing force toward the front side of the guide plate 95. Further, the guide sensor 107 outputs the position detection data D6 at the "L" level because the projection portion 95f is shielded from light. The position detection data D6 of the "L" position indicates the state of the lock guide 95.

Fig. 42 is a top view showing an example of the positional relationship of the cam plate 99 in the guide mechanism 8A at the time of return of the label holding mechanism 3A. The control unit 110 operates the lock mechanism 81 shown in Fig. 42 to control the drive of the label holding drive mechanism 9A to return the curl guide 30 to the standby position. At this time, even if the curling guide 30 retreats to the standby position, the half moon-shaped portion of the cam plate 99 is engaged with the opening portion 95d and the butt guide 95 is returned to position beyond the biasing force of the springs 82a and 82b.

After the curl guide 30 is retracted, the guide 95 does not fly out due to the latching with the cam plate 99. Thus, in the state of the lock guide 95, the packaged bag 14 is easily taken out. The guide sensor 107 outputs a position detection data D6 of "L" position (the lock mechanism operates) by blocking the projection portion 95f.

In this manner, the baler 100 wraps the strip-shaped packaged article 13' around the hem of the bag 14 by the two engaging holes 11m provided in the label 1A, and when the label 1A is attached to the hem of the bag 14, The movable guide mechanism 8A having the notch portion 95b conveys the label 1A to the hem of the bag 14 inserted into the installation space portion 92b while the label holding mechanism 3A and the guide 95 hold the label 1A.

Therefore, the label 1A is prevented from coming off during the label transport. Further, since the notch portion 95b for guiding the bag gusset extends from the installation space portion 92b to the outside, the hem of the bag 14 is surely inserted into the installation space portion 92b before the label is conveyed. Thereby, a highly reliable label mounting device or the like is provided.

Fig. 43 is a top view showing an example of the configuration of the stepping path in the baler 100. In this example, a case in which a passage through which the wrapping device 13 such as a twisted belt, a string, or a wire is passed is formed by a plurality of members is exemplified. The baler 100 shown in Fig. 43 includes a label holding mechanism 3A, a package forming mechanism 6A, a label holding drive mechanism 9A, and a step path structure 60. The label holding mechanism 3A has a packing path 303 at a position indicated by a broken line at the curl guide 30, and passes the packing 13 (refer to Fig. 29).

In this example, the package forming mechanism 6A is provided to abut against the front end portion of the curl guide 30 to form the packing 13 passing through the packing path 303. The package forming mechanism 6A has the package induction paths 601 and 602 that communicate with the above-described packing path 303, and has a proximal arm 61a (toward the left side of the package forming mechanism 6A) and a proximal arm 61b (same side). The proximal arm 61a functions as a rotatable first proximal arm, and is disposed on the left side of the package forming mechanism 6A. The terminal end of the cut package 13' is closed from the left side toward the center portion, and the drive of the label holding drive mechanism 9A is obtained. Force and action.

The proximal arm 61b forms a rotatable second proximal arm disposed on the right side of the package forming mechanism 6A, and the front end of the cut package 13' is moved from the right side toward the central portion to obtain the driving force of the label holding drive mechanism 9A. action. Thereby, the packing 13' of the engaging hole 11m at the two positions of the label 1A is formed by approaching the center portion with the proximal arms 61a and 61b.

In this example, a connecting block 31a is disposed between the proximal arm 61a and the curling guide 30, and the packing 13 is guided to the packing path 303 of the curling guide 30. In the proximal arm 61a and the connecting block 31a, which is a portion through which the packing 13 passes, the first packing guide path 601 is set to induce a passage of the front end portion of the packing 13.

Further, a connecting block 31b is disposed between the curl guide 30 and the proximal arm 61b, and the packing 13 pulled out (pushed out) from the packing path 303 of the curling guide 30 is guided to the proximal arm 61b. In the connecting block 31b and the proximal arm 61b, which is a portion through which the packing 13 passes, the second packing guide path 601 is set to induce a passage of the front end portion of the packing 13. Such a package inducing path 601, a packing path 303, and a package inducing path 602 form a stepped path structure of the packing 13.

Further, on the upstream side of the package induction paths 601, 602, there is a package carrying mechanism 5A, and the package guides 303 and the package guide paths 601, 602 guide the package 13 by abutting against the package forming mechanism 6A. The label holding mechanism 3A performs the engaging holes 11m at two positions of the aligned label 1A.

Further, the bag-converting mechanism 7A described in Fig. 40 and the guide mechanism 8A described in Fig. 39 are attached to the space between the left and right proximal arms 61a and 61b of the packaging device rowing mechanism 6A. The guide plate mechanism 8A conveys the label 1A to the hem of the bag 14 inserted into the installation space portion 92b while the label 1A is held by the curl guide 30 and the guide 95. The packing and contracting mechanism 7A is twisted and twisted by the cut package 13' which is close to the center portion of the package forming mechanism 6A.

The label holding drive mechanism 9A moves the label holding mechanism 3A in a direction approaching or away from the package forming mechanism 6A in addition to the driving of the packing mechanism 6A, and the label holding mechanism 3A abuts on the package forming The mechanism 6A operates by causing the packing path 303 to communicate with the package induction paths 601 and 602.

Fig. 44 is a partially broken top view showing a configuration example of the step path in the package forming mechanism. Fig. 45 to Fig. 47 are enlarged views showing an example of the setting of the middle step of the stepped path structure 60.

According to the stepped path structure 60 of the package forming mechanism 6A shown in FIG. 44, the package guiding paths 601 and 602 and the packing path 303 are set such that the guiding surface on the upstream side is relatively high in the entering direction of the packing device 13, The guide surface on the downstream side is relatively low. The step portion Ia indicated by the broken line circle in Fig. 44 is set between the cutting member 62 and the proximal arm 61a, and an enlarged view thereof is shown in Fig. 45. The cutting member 62 is attached to the downstream end portion of the belt tilting member 63 (transporting passage), and cuts the packing device 13.

The step portion IIb shown in Fig. 44 is set as a communication connecting portion between the proximal arm 61a and the connecting block 31a, and a communication connecting portion between the connecting block 31a and the packing path 303 of the curling guide 30, and an enlarged view thereof It is shown in Figure 46. The step portion IIIc shown in Fig. 44 is set as a communication connecting portion between the packing path 303 and the connecting block 31b of the curling guide 31b and the connecting portion between the connecting block 31b and the proximal arm 61b, and the enlarged view thereof is shown. Expressed in Figure 47.

According to the step portion Ia shown in Fig. 45, the end portion on the downstream side of the cutter 62 becomes high, and the end portion on the upstream side of the proximal arm 61a is set lower than the downstream end portion of the cutter 62. A first step ε1 is set between the cutting member 62 on the upstream side and the proximal arm 61a on the downstream side.

According to the step portion IIb shown in Fig. 46, the end portion on the downstream side of the proximal arm 61a becomes higher, and the end portion on the upstream side of the connecting block 31a is set lower than the downstream end portion of the proximal arm 61a. The second step ε2 is set between the upstream side proximal arm 61a and the downstream side connecting block 31a.

Further, the end portion on the downstream side of the connection block 31a becomes high, and the end portion on the upstream side of the packing path 303 of the curl guide 30 is set to be lower than the downstream end portion of the connection block 31a. A third step ε3 is set between the connecting block 31a and the packing path 303 of the curling guide 30.

According to the step portion IIIc shown in Fig. 47, the end portion on the upstream side of the proximal arm 61b is set lower than the downstream end portion of the packing path 303 of the crimping guide 30. A fourth step ε4 is set between the packing path 303 of the curl guide 30 and the proximal arm 61b.

Moreover, the end portion on the upstream side of the connecting block 31b is set to be lower than the downstream end portion of the proximal arm 61b. A fifth step ε5 is set between the connecting block 31b and the proximal arm 51b. Thus, the step differences ε1, ε2, ε3, ε4, and ε5 of a total of five positions are set.

Each of the step differences ε1, ε2, ε3, ε4, and ε5 has the same value, for example, about 1 to 2 [mm], and the individual optimum values are individually set for each of the step differences ε1, ε2, ε3, ε4, and ε5. Further, an adjustment mechanism is separately provided in the step portions Ia, IIb, and IIIc, and the step differences ε1, ε2, ε3, ε4, and ε5 can be adjusted, respectively.

Fig. 48 is a top view of the package forming mechanism 6A of the penetration example of the packing device 13. According to the package forming mechanism 6A shown in Fig. 48, the rotatable proximal arm 61a for bringing the cut package 13' closer to the center portion and the package to the label holding mechanism 3A are sequentially disposed on one side thereof. The connecting block 31a, which is adjacent to the connecting block 31a and communicates with the packing guide passage 303 of the curling guide 30 of the label holding mechanism 3A, is adjacent to the packing path 303 and is sequentially arranged on the other side of the packing forming mechanism 6A. The connecting block 31b of the packing 13 pulled out by the packing path 303 and the rotatable proximal arm 61b which brings the packing 13 close to the central portion.

In this example, the packing member 13 inserted from the belt tilting member 63 is moved to the packer induction path 601 by the step difference ε1 set between the cutter member 62 and the proximal arm 61a at the step portion Ia of the packer induction passage 601. The section of the section IIb.

In the step portion IIb, the packing 13 from the proximal arm 61a passes through the step ε2 set between the proximal arm 61a and the connecting block 31a and the step ε3 set between the connecting block 31a and the packing path 303 of the curling guide 30. The transition to the step portion IIIc of the packer induction path 602 is made.

In the step portion IIIc, the packing 13 pulled out from the downstream side of the packing path 303 of the curling guide 30 passes through the step ε4 set between the packing path 303 and the proximal arm 61b and is set to the connecting block 31b and the proximal arm. The step ε5 between 61b reaches the approach arm 61b. Then, the packing 13 is cut by the cutting member 62 provided on the downstream side with the inclined member 63.

In this way, in the stepped path structure of the baler 100, the entering direction of the packing device 13 is set as the connecting portion between the packing guide passages 601 and 602 and the large package passage 303, and the upstream leading surface is relatively raised. The guide surface on the downstream side is relatively low. In the above example, the step differences ε1, ε2, ε3, ε4, ε5 of any one of them are set such that the downstream side is lower than the upstream side.

Therefore, the strip-shaped packaged goods 13' are bundled around the folds of the bag 14 by the two engagement holes 11m, 11m provided in the label 1A, and when the label 1A is attached to the fold of the bag 14, Since the front end of the packaging device 13 can be prevented from abutting on the front end of the package induction paths 601 and 602, the packaging device 13 can be made from the packaging tool forming mechanism even if the introduction structure of chamfering or the like is not provided on the package induction paths 601 and 602. The packer induction path 601 of 6A smoothly passes through the package path 303 of the curl guide 30. Further, the packing device 13 can be smoothly passed from the packing path 303 through the package induction path 602 of the package forming mechanism 6A. Thereby, the conveyance failure of the packaging tool 13 can be prevented.

Fig. 49 is a block diagram showing a configuration example of a control system of the baler 100. The control system shown in Fig. 49 has a control unit 110 and motor drive units 141b, 150i, 170c, and 193. The control unit 110 is composed of an I/O interface 111, a RAM 112, an EEPROM 113, a CPU 114, and a system bus bar 115. Further, the label transport motor 41b and the feed motor 93 in the drawing are the same as those shown in Figs. 6 and 7. Further, the guide sensor 107 is the same as that shown in Figs. 39 to 42.

The EEPROM (Eelctrically Erasable Programmable Read-Only Memory) 113 of the control unit 110 is connected to the CPU (Central Processing Unit) 114 via the system bus bar 115. In the EEPROM 113, the control program of the baler 100 is stored. The control program detects that the bag 14 is attached to the packing port 103, transports the label 1A, and sends out the packing device 13, and cuts the packing 13 passing through the label 1A to perform the twisting process.

A RAM (Random Acess memory) 112 is connected to the CPU 114 via the system bus 115. When the power of the baler 100 is started, the control program read from the EEPROM 113 in the RAM 112 is developed by the CPU 114.

The CPU 114 is connected to the operation unit 106 via the I/O interface 111, and the operation data D1 indicating the tag 1A is input from the operation unit 106. The CPU 114 adjusts (changes) the amount of delivery of the tag 1A based on the operation data.

Further, the guide sensor 107 is connected to the CPU 114 via the I/O interface 111, and outputs the position detection data D6 detected by the guide sensor 107. The position sensing data D6 is information indicating that the bag 14 is attached to the packing port 103.

Moreover, the bag sensor 108 is connected to the CPU 114 via an I/O interface. The bag sensor 108 detects whether or not the bag 14 is disposed in the packing port 103 by the arm 121' (refer to Fig. 37) provided in the vicinity of the packing opening 103. The CPU 114 inputs the bag detecting data D7 detected by the bag sensor 108.

The tag sensor 109 is connected to the CPU 114 via the I/O interface 111. The label sensor 109 is provided in the label transport path I of the transport mechanism 4A (see FIG. 27B). When the tag 1A is transported, the CPU 114 inputs the transport material D8 of the transport label 1A from the tag sensor 109. In the case where the label 1A is not transported, the CPU 114 inputs, from the label sensor 109, the conveyance data D8 indicating that the label 1A is not conveyed. The CPU 114 outputs the control data D2 for rotating the label transport motor 41b to the motor drive unit 141b of the label transport mechanism 4A based on the transport data D8.

After the CPU 114 inputs the position detection material D6 from the guide sensor 107, the control data D3 for controlling the proximity motor 93 is output to the motor drive unit 193 of the label holding drive mechanism 9A. The motor drive unit 193 generates a motor control signal S3 from the control data D3 and outputs it to the feed motor 93. The feed motor 93 rotates in accordance with the motor control signal S3, and the actuation plate 32 slidably screwed to the guide screw shaft 94 shown in Fig. 7 slides in the direction of the arrow Q2 via the gears 93a, 94a, so that the curl guide 30 moves from the home position HP to the end position P1.

After the actuation plate 32 slides, the CPU 114 outputs the control data D4 of the package conveyance motor 50i for controlling the package conveyance mechanism 5A to the motor drive unit 150i. The motor drive unit 150i generates a motor control signal S4 from the control data D4 and outputs it to the package conveyance motor 50i. The packer conveyance motor 50i rotates the packer transport roller 50a shown in Fig. 7 in accordance with the motor control signal S4, and the packer 13 is pulled out from the spool 52 and sent out to the belt tilting member 63.

At this time, while the CPU 114 outputs the control data D4, the control data D10 for driving the solenoid 89a of the brake mechanism 89A is output to the solenoid drive unit 894a. The solenoid drive unit 894a receives the drive control data D10 to energize the solenoid 89a. The solenoid 89a is energized to contract the movable iron core 89c. Thereby, as shown in FIG. 17B, the braking state of the reel 52 is released.

Further, when the packager 13 is pulled out by the package transport roller 50a, the CPU 114 outputs the control data D10 for stopping the solenoid 89a to the solenoid drive unit 894a. The solenoid 894a receives the control data D10 for stopping and blocks the energization of the solenoid 89a. The energization of the solenoid 89a is blocked, and the movable iron core 89c is made deep by the elastic force of the compression spring 89b (see Fig. 12B). Thereby, as shown in FIG. 16B, the braking force acts on the spool 52. Further, although only the brake mechanism 89A will be described, the above-described brake mechanisms 89B to 89D are also controlled in the same manner.

After the package 13 is sent out to the belt tilting member 63 of the package forming mechanism 6A, the CPU 114 again outputs the control data D3 for controlling the proximity motor 93 to the motor driving portion 193. The motor drive unit 193 generates a motor control signal S3 from the control data D3 and outputs it to the feed motor 93. The proximity motor 93 rotates according to the control signal S3, and the actuating plate 32 shown in FIG. 7 slides in the direction of the arrow Q2, and the link roller 97 is pressed by the roller arm 101 attached to the lower end of the actuating plate 32. The cutting member 62 and the proximal arms 61a, 61b coupled to the connecting roller 97 are driven.

After the CPU 114 drives the cutting member 62 and the proximal arms 61a, 61b, the control data D5 for controlling the torsion motor 70c is output to the motor driving portion 170c of the packing device contracting mechanism 7A. The motor drive unit 170c generates a motor control signal S5 from the control data D5 and outputs it to the torsion motor 0c. The torsion motor 70c rotates the torsion motor 70 shown in Fig. 7 based on the motor control signal S5.

After the rotation of the torsion motor 70, the CPU 114 outputs the control data D3 for inverting the proximity motor 93 to the motor driving portion 193. The motor drive unit 193 generates a motor control signal S3 from the control data D3 and outputs it to the feed motor 93. The proximity motor 93 is reversed according to the motor control signal S3, and the actuating plate 32 shown in Fig. 7 slides in the direction of the arrow Q3 opposite to the above-mentioned arrow Q2, and the curl guide 30 is returned from the packing position P1. Starting position HP.

After the CPU 114 returns the curl guide 30 to the lift position HP, the control data D2 for rotating the label transport motor 41b is output to the motor drive portion 141b. In this example, the CPU 114 inputs the operation data D1 from the operation unit 106, and controls the amount of delivery of the label 1A based on the operation data D1. For example, when the CPU 114 inputs the operation data D1 indicating that the total length of the tag has increased, the control unit D2 that increases the amount of delivery of the tag (for the long tag) is output to the motor drive unit 141b.

In addition, when the operation data D1 indicating that the total length of the label is short is input, the CPU 114 outputs the control data D2 of the label (the general label 1A) to the motor drive unit 141b. The motor drive unit 141b generates a motor control signal S2 from the control data D2 and outputs it to the label conveyance motor 41b. The label transport motor 41b rotates according to the motor control signal S2, and rotates the label transport roller 41a shown in FIG. 27A, and the label 1A stored in the lowermost portion of the cassette 40 is fed out one by one.

In this example, the control data D2 for the long label is different from the control data D2 for the general label 1A, and in the case of the control data D2 for the long label, after the conveyance of the package 13, the label is conveyed. The sub-41a rotates to send the rear end portion of the information presentation unit 10C of the long label 1A' remaining in the cassette 40. Thereby, the label is completely delivered in accordance with the entire length of the label. When the label 1A is sent out in one piece, the CPU 1144 waits for the bag detection data D7 detected by the bag sensor 108 to be input.

Further, in addition to the method of inputting the output amount of the operation data by the operation data D1 from the operation unit 106, the method of detecting the label 1A and controlling the amount of the label 1A is detected. For example, a reflection type full-length sensor 116 (not shown) is provided at a position where the entire length of the discrimination label 1A (a label flying from the rear end portion of the cassette 40) is detected, and the label transport mechanism is detected. The total length of the label 1A carried by 4A.

At this time, the tag full length sensor 116 detects the length of the long tag 1A' longer than the tag 1A. The CPU 114 inputs the detection data D9 from the tag full-length sensor 116, determines the label delivery amount (number of rotations) of the label conveyance motor 41b based on the detection data D9, and controls the label conveyance amount of the label conveyance motor 41b based on the determination result.

For example, when the tag full-length sensor 116 detects the rear end portion of the tag 1A or the like, when the total length of the tag 1A or the like becomes long (detects the length of the long tag 1A' longer than the tag 1A), the ratio tag is displayed. The detection data D9 of the long length of 1A is output to the CPU 114, and when the total length of the tag 1A is shortened, the detection data D9 whose total length of the tag is shortened is displayed.

When the CPU 114 inputs the detection data D9 indicating that the total length of the label is long, the control data D2 (for the long label longer than the label 1A), which has a large amount of the label, is output to the motor driving unit 141b. Thereby, the total length of the label is detected instantaneously and the amount of label delivery is controlled.

Even in this case, since the control data D2 for the long label is different from the control data D2 for the general label 1A, in the case of the control data D2 for the long label, after the conveyance of the packaging member 13, the label conveying roller is caused. The 41a is rotated and controlled to send the rear end portion of the information presentation portion 10C of the long label 1A' remaining in the cassette 40. Thereby, the label can be completely dispensed with the entire length of the label.

In the above two examples, after the label 1A is fed one by one, the position detection data D6 indicating the presence or absence of the mounting pocket 14 which can be obtained from the guide sensor 107 is input to the CPU 114. Thereafter, the CPU 114 waits for the state in which the operation data D1 is input from the operation unit 106. Thus, the baler 100 is controlled by the control program stored in the EEPROM 13.

Here, the power supply of the baler 100 will be described. The power source of the baler 100 has, for example, a power supply circuit 20 that can be used by being connected to AC 100V. The AC switch is connected between the AC power source (100V) and the power supply circuit 20, and the AC power source is ON when in use. The power supply circuit 20 has a power conversion function (not shown), for example, a conversion from an AC power source to a main power source for driving the motor (for example, DC 12 V) and a DC power source (DC 5 V) for driving the control unit 110. Here, the main power source of the baler 100 is the motor drive unit 141b that supplies the drive voltage to the label transport mechanism 4A, the motor drive unit 150i of the package transport mechanism 5A, the motor drive unit 170c of the package contracting mechanism 7A, and the label clamping drive. Motor 93 of mechanism 9A.

In this example, the main switch 120 (such as a relay switch) is connected between the power supply circuit 20 and the motor drive unit 141b, and via the bag sensor switch 121 (such as a relay switch), the motor drive unit 150i and the motor drive unit 170c. The motor 93 is connected to the load side of the main switch 120. When the main switch 120 is turned ON, the drive voltage is supplied to the motor drive unit 141b, and the bag sensor switch 121 is turned ON, and the drive voltage is supplied to the motor drive unit 150i, the motor drive unit 170c, and the motor 93.

The main switch 120 turns on the CPU 114 based on the operation data D1 input from the operation unit 106, for example, information indicating that D1 = "start packing". The bag sensor switch 121 causes the CPU 114 to be turned on based on the bag sensor 108 displaying the bag detecting data D7, for example, D7 = "bagged" information. With such a dual power supply countermeasure, safety for the user is taken into consideration during operation.

Next, a series of operation examples of the packing process will be described in sequence while referring to FIGS. 50 to 58. Fig. 50 and Fig. 51 are flowcharts showing an operation example (the first and second) of the baler 100. Fig. 52 to Fig. 58 are perspective views showing an operation example of the label carrying mechanism 3A and the guide mechanism 8A when the label is conveyed.

In this embodiment, the AC switch 201 of the baler 100 is turned ON, and the control program stored in the EEPROM 113 of the control unit 110 shown in Fig. 49 is read from the CPU 114 and developed in the RAM 112, and is set in the power saving mode. The power-saving mode means that the main switch 120 and the bag sensor switch 121 shown in Fig. 49 are OFF, the drive voltage is not supplied to the motor drive units 141b, 150i, 170c, and 193, and the power supply for the low voltage is supplied to the control unit. The state of 110.

Further, the front end of the packing 13 bundled around the spool 52 is set at the position of the cutting member 62 shown in Fig. 7. Further, the label 1A or the long label 1A' is stacked and stored on the cassette 40 of the label transport mechanism 4A. The state of the baler 100 is such that the front end of the packing 13 bundled around the reel 52 is set at the position of the cutting member 6 shown in Fig. 7. Further, the label 1A is stacked and stored on the cassette 40 of the label transport mechanism 4A, and the operation unit 106 switches the label 1A.

As a condition of the packing process, in step ST1 shown in FIG. 50, the CPU 114 stands by "start packing" in order to turn on the main switch 120 of the baler 100. At this time, the user operates the start button or the like (not shown) on the operation unit 106 to display "start packing". In response to this, the operation unit 106 outputs information indicating that the operation data D1 = "start packing" to the CPU 114. The CPU 114 turns on the main switch 120 in accordance with the operation data D1.

Thereby, the drive voltage is first supplied from the power supply circuit 20 to the motor drive unit 141b via the main switch 120. At this time, since the bag sensor switch 121 is OFF, the drive voltage is not supplied to the motor drive unit 150i, the motor drive unit 170c, and the motor 93. When the CPU 114 is "started packing", the control program stored in the EEPROM 113 of the control unit 110 shown in Fig. 49 is read and expanded in the RAM 112.

In step ST2, the CPU 114 determines whether or not the tag 1A (or the long tag 1A') is carried. For example, when the CPU 114 inputs the conveyance data D8 indicating that the label 1A is not to be conveyed from the label sensor 109 shown in FIG. 27B, the CPU 114 proceeds to step ST3. When the CPU 114 inputs the conveyance data D8 indicating the conveyance label 1A from the label sensor 109, the CPU 114 proceeds to step ST4.

In step ST3, the CPU 114 controls the transport label 1A. For example, the CPU 114 controls the label 1A that is rotated by the label transport roller 41a and accommodated in the lowermost portion of the cassette 40 to be fed one by one. At this time, according to the transport example of Fig. 54, in the standby state of the label holding mechanism 3A and the guide mechanism 8A, the label 1A is held by the label hanging claw portion 30b of the curl guide 30. Further, the protrusion portion 95f for the sensor mark outputs the position detection data D6 of the "H" level to the control unit 110 because the slit of the guide plate 107 is not traversed.

Then, the process proceeds to step ST4, and the CPU 114 determines whether or not the bag 14 is disposed at the packing port 103 of the baler 100. For example, the user inserts (arranges) the bag 14 into the packing opening 103 shown in Fig. 52. In this example, the guide plate 95 is pushed by the bag 14 while being inserted into the installation space portion 92b. At this time, the user pushes the triangular space area of the packing opening 103 and inserts the bag 14.

For example, in the packing port 103, when the bag 14 is inserted toward the apex of the triangle in the initial stage, the guide plate 95 is pressed by the bag 14 in the direction in which it enters toward the inside. According to the intermediate stage of the mounting operation of the bag 14 shown in Fig. 53, the guide plate 95 and the arm 121' are pushed by the bag 14 and inserted into the space portion 92b. Thereafter, at a point in time when the bag 14 is pressed toward the mounting space portion 92b, the guide plate 95 flies outward again. The outward flight is performed by the biasing force of the spring.

Thereby, the arm 121' shown in Fig. 52 is rotated, and one end of the arm 121' is detected by the bag sensor 108. The bag sensor 108 outputs information indicating that the bag detection data D7 = "bag" is output to the CPU 114. The CPU 114 turns the bag sensor switch 121 ON according to the bag detection data D7 = "bags" (dual power supply countermeasure).

That is, when the CPU 114 inputs the bag detecting material D7 from the bag sensor 108, the bag sensor switch 121 is turned ON and proceeds to step ST5. Moreover, when the CPU 114 does not input the bag detection data D7 from the bag sensor 108, it is determined whether or not the bag 14 is placed again.

In step ST5, the CPU 114 determines whether or not the guide 95 is present at a predetermined position. In the above example, when the user places the bag 14 on the packing opening 103, the guide 95 of the disposing process shown in Fig. 52 is temporarily pressed by the bag 14 to slide as shown in Fig. 53. At this time, the CPU 114 determines whether or not the temporarily pushed guide 95 has returned to the original position. For example, the CPU 114 outputs from the guide sensor 107 through the slit of the penetrating guide sensor 107 (refer to FIGS. 39 and 23A) by the protrusion 95f for the sensor at the rear end of the guide 95. The low level or high position detection data D6 determines whether the guide 95 has returned to the original position.

Further, the guide sensor 107 detects the slide guide, and outputs the position detection data D6 indicating that the bag 14 is mounted to the CPU 114. In this example, when the slit of the guide sensor 107 is blocked by the projection 95f, the CPU 114 inputs the position detection data D6 of the "L" level, and when the guide sensor 107 is not shielded from light, the CPU 114 inputs Position detection data D6 at "H" level.

Therefore, when the guide plate 95 is not returned to the original position, that is, in a state where the bag 14 is held beyond the guide 95 and the guide 95 is pushed, the guide sensor 107 is shielded from light and outputs the position of "L" position. Test data D6.

In this manner, when the CPU 1110 inputs the position detection data D6 at the "L" level and the position detection data D6 at the "H" position is not output from the guide sensor 107, it is determined that the bag 14 is beyond the guide 95 and does not move to Stop the control in the next step. When the position detection data D6 of the "H" level is not output from the guide sensor 107, for example, 7 to 10 seconds, the CPU 114 generates an alarm by a click or the like. When the position detection data D6 of the "H" level is input, the CPU 114 confirms (identifies) that the guide 95 has returned to the original position, and proceeds to step ST6.

In step ST6, the CPU 114 determines whether or not the general tag 1A or the long tag 1A' is set by the operation unit 106. For example, when the CPU 114 inputs the operation data D1 of the general tag 1A from the operation unit 106, the CPU 114 proceeds to step ST7.

At step ST7, the CPU 114 moves the curl guide shown in Fig. 7. For example, the CPU 114 rotates the proximity motor 93, and the actuator plate 32 shown in Fig. 7 moves in the direction of the arrow Q2, and the curl guide 30 moves from the home position HP to the packing position P1, and the process proceeds to step ST8.

At this time, according to the conveyance example shown in Fig. 56, the label holding drive mechanism 9A performs the late movement of the curl guide 30 from the position shown in Fig. 55, and pushes the guide 95 with the label hanging claw 30b. In this late movement, the front end portion of the curling guide 30 abuts against the front end portion of the guide 95, and the rear end portion of the protruding portion 95g of the guide 95 abuts against the front end portion of the rail member 92h. At this point of time, the conveyance of the label 1A toward the installation space portion 92b is completed.

In step ST8, the CPU 114 carries the packing device 13. For example, the CPU 114 outputs the control data D10 for driving the solenoid 89a of the brake mechanism 89A to the solenoid driving portion 894a. The solenoid drive unit 894a receives the control data D10 for driving and energizes the solenoid 89a. The solenoid 89a is energized to contract the movable iron core 89c. Thereby, as shown in Fig. 17B, the braking state of the reel 52 is released.

Further, the CPU 114 rotates the package transport motor 50i, and the package 13 is pulled out from the spool 52 and sent out to the belt tilting member 63. At this time, according to the transport example shown in Fig. 57, the belt clamping drive mechanism 9A moves the curl guide 30 shown in Fig. 54 from the standby state in advance, and the front end portion of the curl guide 30 is biased via the label 1A. Connected to the front end of the guide 95. In other words, the label 1 is prevented from coming off by the state in which the guide sheet 95 and the curl guide 30 sandwich the label 1A. Thereafter, in this state, the label 1A moves toward the mounting space portion 92b. The guide sensor 107 outputs the position detection data D6 of the "L" position due to the cross section of the projection 95f.

Further, the CPU 114 outputs the control data D10 for stopping the solenoid 89a to the solenoid drive unit 894a when the package conveyance motor 50i is finished with the package puller. The solenoid driving unit 894a inputs the control data D10 for stopping and blocks the energization of the solenoid 89a. The energization of the solenoid 89a is blocked, and the movable iron core 89c is extended by the elastic force of the compression spring 89a (see Fig. 12B). Thereby, as shown in FIG. 16B, the braking force acts on the spool 52. After that, the process proceeds to step ST9.

In step ST9, the CPU 114 controls the cutting of the packing 13 and joins the front end portion and the rear end portion of the cut package 13'. For example, the CPU 114 rotates the proximity motor 93 again, and the actuating plate 32 shown in FIG. 9 slides in the direction of the arrow Q2, and the connecting roller 97 is pressed by the roller arm 101 attached to the lower end portion of the actuating plate 32. The cutter 62 and the proximal arms 61a and 61b that drive the coupling roller 97 are coupled to each other, and the front end portion and the rear end portion of the packaging material 13' cut from the packaging material 13 are brought close to each other while the packaging tool 13 is cut.

At this point of time, the protrusion 95f for the sensor mark is shielded from light by the slit of the guide plate sensor 107, and the position detection data D6 of the "L" level is output to the control unit 110. Thereafter, the control unit 110 activates the position detecting material D6 to drive the label holding drive mechanism 9A, and the packing tool 13 is formed by the packing tool forming mechanism 6A, and the label 1A is cut by the torsion arm 70 of the packing and contracting mechanism 7A. Packing 13' bandage. Then, the process proceeds to step ST13 shown in Fig. 51.

In step ST13, the CPU 114 controls and twists the cut package 13'. For example, the CPU 114 rotates the torsion motor 70c to rotate the torsion arm 70 shown in Fig. 7 to twist the package 13' after the torsion arm 70 holds the front end portion and the rear end portion. Further, as shown in Fig. 42, the guide plate 95 is locked by the cam plate 99 attached to the torsion arm 70. When the guide 95 is returned, pushing the label 1A causes a problem that the label 1A is deformed or the package is unplugged.

With regard to the lock function, the control unit 110 operates the lock mechanism 81 at the same time as the packing process is completed according to the transport example shown in Fig. 57. In the lock mechanism 81, the half-moon cam plate 99 of the torsion arm 70 of the packing and contracting mechanism 7A is stopped at a position rotated by 180° from the standby state. By this rotation, the cam plate 99 is engaged with the opening 95d for the cam engagement of the guide 95, and is stopped. In other words, the half moon portion of the cam plate 99 is stopped with respect to the chord shape of the opening portion 95d, and the cam plate 99 is engaged with the opening portion 95d to lock the biasing force toward the front side of the guide plate 95. Further, the guide sensor 107 outputs the position detection data D6 at the "L" level because the projection portion 95f is shielded from light. The position detection data D6 of the "L" position indicates the state of the lock guide 95. Then, the process proceeds to step ST14.

In step ST14, the CPU 114 controls the left and right proximal arms 61a, 61b and the cutter 62 to return to the original position. At this time, according to the conveyance example shown in Fig. 58, the control unit 110 operates the lock mechanism 81 to drive the label holding mechanism 9A to return the curl guide 30 to the standby position. For example, the CPU 114 reverses the proximity motor 93, causes the actuation plate 32 shown in Fig. 7 to slide in the direction of the arrow Q3 opposite to the above-mentioned arrow Q2, and the curl guide 30 returns from the packing position P1 to the home position HP.

At this time, the contact between the roller arm 101 attached to the lower end portion of the actuating plate 32 and the connecting roller 97 is released. The tension spring 122 that is placed between the connecting roller 97 and the engaging shaft 97' is often biased toward the engaging shaft 97' side of the connecting roller 97, and the roller arm 101 shown in Fig. 6 is released. When the connecting roller 97 abuts, the connecting roller 97 moves in the direction of the arrow Q3. The coupling roller 97 is pressed back in conjunction with the cutter link 62c of the cutting member 62. The link roller 97 moves in the direction of the arrow Q3.

Thereby, the cutter 62 that is linearly coupled to the coupling roller 97 is retracted from the front end of the belt tilting member 63 of the package conveying mechanism 5A. In this example, even if the curling guide 30 retreats to the standby position, the partial pressure of the springs 82a and 82b is increased, and the half moon-shaped portion of the cam plate 99 is engaged with the opening 95d, thereby suppressing the return of the guide 95.

Moreover, after the curling guide 30 is retracted, the guide plate 95 does not fly out because it is locked by the cam plate 99. Thus, in the state of the lock guide 95, the packaged bag 14 is easily taken out. Since the guide sensor 107 is shielded from light by the protruding portion 95f, the position detection data D6 at the "L" level is output (the lock mechanism operates). At the same time as the above-described retracting process of the cutter 62, the right and left close arms 61a and 61b that are engaged with the coupling roller 97 return to the original position, and a part of the package induction paths 601 and 602 are again formed, and the process proceeds to step ST15.

In step ST15, the CPU 114 determines whether or not the bag 14 is taken out. At this time, the bag sensor 108 detects whether or not the arm 121' which is rotated by the bag 14 in the above-described step ST4 is rotated back to the original position due to the removal of the bag 14.

For example, when the bag 14 is not pulled out from the packing port 103, the CPU 114 re-determines whether or not the bag 14 is pulled out when the bag detecting material D7 indicating that it has not returned to the original position of the arm 121 is input from the bag sensor 108. Then, the bag 14 is pulled out from the packing opening 103, and when the CPU 114 inputs the bag detecting material D7 indicating the return to the original position of the arm 121' from the bag sensor 108, the bag sensor switch 121 is OFF, and the process proceeds to the step. ST16.

In step ST16, the CPU 114 controls to release the guide 95 that is locked in step ST13. For example, the CPU 114 half-rotates the torsion motor 70c, half-rotates the torsion arm 70 shown in Fig. 42, releases the guide 95 that is locked by the cam plate 99 attached to the torsion arm 70, and moves to step ST17.

In step ST17, the CPU 114 controls loading (handling) the label 1A to the curl guide 30. For example, the CPU 114 controls the label transport roller 41a to rotate, and feeds the label 1A stored in the lowermost portion of the cassette 40 one by one. This label loading process is to be completed before the next packaging process. According to the transport example shown in Fig. 54, in the standby state of the label holding mechanism 3A and the guide mechanism 8A, the label 1A is held by the label hanging claw 30b of the curl guide 30. Further, since the protruding portion 95f for the sensor mark does not cross the slit of the guide sensor 107, the position detection data D6 of the "H" level is output to the control portion 110. Then, the process proceeds to step ST18.

In step ST18, the CPU 114 inputs information for turning off the main switch 120, that is, inputting information of the operation data D1 = "packing end" from the operation unit 106, and then turning off the main switch 120 based on the operation data D1 = "packing end". When the main switch 120 is not OFF, the process returns to step ST2 and the above-described processing is repeated. The packing process is completed by the main switch 120 = OFF. Moreover, the control unit 110 shifts to the sleep state. The sleep state refers to a state in which the drive voltage is not supplied from the power supply circuit 20 to the motor drive unit 141b, the motor drive unit 150i, the motor drive unit 170c, and the motor 93, and the determination function, the timer function, and the memory function of the CPU 114 of the control unit 110 are activated. Other functions are inactive (power saving mode).

Further, in step ST6, when the CPU 114 inputs another material (hereinafter referred to as a long label 1A') by the operation unit 106, the process proceeds to step ST10. In step ST10, the CPU 114 sends the long label 1A' while moving the curling member 30. For example, the CPU 114 rotates the proximity motor 93 to slide the actuation plate 32 shown in Fig. 7 in the direction of the arrow Q2, and moves the curl guide 30 from the home position HP to the packing position P1. At this time, the CPU 114 controls the rotation of the curl guide 30, and rotates the label transport roller 41a shown in Fig. 27 to send the rear end portion of the information presentation portion 10C of the long label 1A' remaining in the cassette 40. The process proceeds to step ST11.

In step ST11, the CPU 114 carries the packing device 13. For example, the CPU 114 rotates the packer conveyance motor 50i, pulls the packer out of the spool 52, and feeds it to the belt tilting member 63, and proceeds to step ST12.

In step ST12, the CPU 114 cuts off the package 13 and controls the label 1A to be sent out while the front end portion and the rear end portion of the packaged package 13' after the cutting of the package 13 are brought into close contact with each other. For example, the CPU 114 further rotates the proximity motor 93, and the actuating plate 32 shown in Fig. 7 slides in the direction of the arrow Q2, and the roller arm 101 attached to the lower end portion of the actuating plate 32 presses the connecting roller 97 to drive the motor 97. The cutting member 62 and the left and right proximal arms 61a and 61b that are connected to the roller 97 are connected to each other, and the packaging device 13 is cut, and the front end portion and the rear end portion of the packaging device 13' after the packaging device 13 is cut are controlled to be close to each other. Combine.

At this time, the CPU 114 causes the actuator plate 32 to slide in the direction of the arrow Q2, and again rotates the label transport roller 41a to completely feed the rear end portion of the information presentation portion 10C of the long label 1A' remaining in the cassette 40. Then, the process proceeds to step ST13, and the cut package 13' is twisted and packaged. Step ST13 and subsequent steps are as follows (refer to steps ST13 to ST18).

Thus, according to the baler 100 of the first embodiment, the strip-shaped cut-away packing 13' is wound around the fold of the bag 14 using the two engaging holes 11m, 11m provided in the label 1A, when the label 1A When attached to the hem of the bag 14, the label supporting member 30e has a function of hanging on the upper portion of the label at the upper end of the front end of the curling guide 30.

Therefore, the rotation of the label 1A with the label hanging claw portion 30b as the center of rotation can be prevented. Thereby, it is possible to prevent the label from coming off due to the rotation as compared with the case where the label supporting member 30e is not attached. Moreover, the packaging tool 13 inserted from the engaging hole 11m of the one side label 1A is excellent in reproducibility from the other engaging hole 11m. Moreover, the label 1A can be smoothly pulled out from the packaged label transport mechanism 4A to provide a highly reliable baler 100.

Further, the baler 100 has the label supporting member 42c on the label transport mechanism 4A, and when the label transport mechanism 4A transfers the label to the label supporting mechanism 3A, the label supporting member 42c delays the rear end opening period of the label 1A.

Therefore, as shown in Fig. 36, even when the label 1A having a shorter length than the normal length is attached, it is possible to prevent the label from being misrouted and falling off as compared with the case where the label supporting member 42c is not attached. Thereby, the length of the label 1A becomes long and shortens, and the label transport mechanism 4A is transmitted to the label holding mechanism 3A with good reproducibility, thereby providing a baler 100 of high reliability. As a result, the label 1A is reproducibly conveyed from the label support mechanism 3A to the package contracting mechanism 7A.

Further, the baler 100 winds the strip-shaped cut package 13' around the hem of the bag 14 by the two engaging holes 11m, 11m provided in the label 1A, and when the label 1A is attached to the hem of the bag 14, The movable guide mechanism 8A having the notch portion 95b is inserted into the folded portion of the bag 14 of the attachment space portion 92b in a state where the label 1A is held by the label holding mechanism 3A and the guide 95.

Therefore, the label 1A is prevented from coming off during the label transport. Further, since the notch portion 95b for guiding the folding of the bag extends from the mounting space portion 92b to the outside, the folding opening of the bag 14 can be surely inserted into the mounting space portion 92b before the label is conveyed. Thereby, a highly reliable label mounting device or the like is provided.

Further, according to the stepped path structure 60 of the baler 100, in the entering direction of the packing device 13, the upstream side of the packer induction paths 601 and 602 and the packing path 303 is set to be high and the downstream side is low. In the above example, any one of the differences ε1, ε2, ε3, ε4, and ε5 is also set such that the downstream side is lower than the upstream side.

Therefore, the strip-shaped packing device 13' is wrapped around the hem of the bag 14 by the two engaging holes 11m, 11m provided in the label 1A, and when the label 1A is attached to the hem of the bag 14, the packing 13 can be avoided. The front end abuts against the package inducing paths 601, 602, and even if the introduction structure such as chamfering is not provided on the package induction paths 601, 602, the packing device 13 is smoothly inserted from the packing guide path 601 of the package forming mechanism 6A. The packer of the curl guide 30 induces a path 602. Thereby, the conveyance of the packing tool 13 is prevented.

[Embodiment 2]

Fig. 59 is a partially enlarged perspective view showing a configuration example of the label supporting mechanism 2A' of the baler 200 of the second embodiment.

The baler 100 shown in Fig. 59 is provided with a label spring support mechanism 2A'. The label spring mechanism 2A' has a pair of coil spring members 21 and 22 constituting an example of the press-fitting member, and is transported from the label transport mechanism 4A to the label of the pack forming mechanism 6A adjacent to the packer contracting mechanism 7A via the label chucking mechanism 3A. The side end portion of 1A is moved from both sides to operate.

In this example, the label supporting member 30e provided at a predetermined position from the upper portion of the label holding mechanism 3A to the package path 303 holds the upper end of the label 1A while the coil spring members 21, 22 are from the side end of the label 1A. The part is pressed in from both sides. The coil spring members 21 and 22 are spirally processed into a coil shape by a spring member such as a SUS wire, a steel wire, a high carbon steel wire, or a piano wire.

For example, the coil spring member 21 is attached to the intermediate chassis portion 92a in front of the actuation plate 32. The coil spring member 21 has a hollow spiral coil portion 21a, and two spring leg portions (hereinafter referred to as a movable leg portion 21b and a fixed leg portion 21c) that form a predetermined opening angle from the spiral coil portion 21a and extend in different directions.

The spiral coil portion 21a is axially supported by the intermediate chassis portion 92a. For example, the shaft portion 911 that is erected on the intermediate chassis portion 92a is rotatably supported. In order to alleviate the contact with the label 1A, the movable leg portion 21b on one side is curled into a circular shape at the distal end portion, and abuts against the end portion of the holding label 1A. The other fixed leg portion 21c is fixed to the substrate 92i for mounting mechanism on the intermediate chassis portion 92a. For example, the end portion of the substrate 92u is curved to form the protrusion 912 and is fixed inside the protrusion 912.

Further, the coil spring 22 is attached to the intermediate chassis portion 92a located on the label transport mechanism 4A of the clamp label holding mechanism 3A. The coil spring member 22 also has a hollow spiral coil portion 22a and two spring leg portions (hereinafter referred to as a movable leg portion 22b and a fixed leg portion 22c) that form a predetermined opening angle from the spiral coil portion 22a and extend in different directions.

The spiral coil portion 22a is axially supported by the intermediate chassis portion 92a of the label transport mechanism 4A. For example, the shaft portion 913 which is erected on the two intermediate chassis portions 92a, 92a' is rotatably supported. In order to relax the contact with the label 1A, the movable leg portion 22b on one side is curled into a circular shape at the distal end portion, and abuts against the position of the other end portion of the holding label 1A. The other fixed leg portion 22c is fixed to the engaging pin 914 which is erected between the two intermediate chassis portions 92a, 92a'. For the engaging pin 914, for example, a double pin for holding the space between the two intermediate chassis portions 92a and 92a' can be used. The fixing leg portion 22c is wound around the engaging pin 914 and fixed, for example. Thereby, the label spring mechanism 2A' is formed.

Next, a function example of the tag spring support mechanism 2A' of the baler 200 will be described. Fig. 60 and Fig. 61 are top views showing functional examples (1, 2) of the tag spring supporting mechanism 2A'. Fig. 60A is a top view showing a standby example of the label holding mechanism 3A at the time of standby of the label supporting mechanism 2A' and before the label is loaded.

According to the standby state of the label supporting mechanism 2A' shown in FIG. 60A, the movable leg portion 21b of the coil spring member 21 and the movable leg portion 22b of the coil spring member and the curved guiding protrusion portion 30c of the bending guide 30 are provided. In the gap, when the label is loaded, the front end of the label is less likely to be attached to the claw portion 30b and the label supporting member 30e. In the standby state of the label holding mechanism 3A and the label supporting mechanism 2A', the label transport mechanism 4A shown in FIG. 33 is operated to pull the label 1A from the cassette 40 to bend the label claw of the guide 30. The portion 30b is held (refer to Fig. 63).

Here, when the angle formed by the movable leg portion 21b and the fixed leg portion 21c is the opening angle θ1, the opening angle θ1 is, for example, about θ1 = 90°. Moreover, when the angle formed by the movable leg portion 22b and the fixed leg portion 22c is the opening angle θ2, the opening angle θ2 is, for example, about θ2 = 230°. The coil spring members 21 and 22 are maintained in the standby state at the opening angles θ1 and θ2.

Fig. 60B is a top view showing the deformation operation of the label supporting mechanism 2A' after the label is loaded. According to the label supporting mechanism 2A' shown in Fig. 60B, from the standby state shown in Fig. 60A, the label supporting drive mechanism 9A shown in Fig. 7 operates in the direction of the label holding mechanism 3A toward the package forming mechanism 6A. At the time of advancement, the front end portion of the bending guide 30 abuts against the front end portions of the coil springs 21, 22. At this point of time, first, the coil spring members 21, 22 are maintained in the standby state.

Fig. 61A is a top view showing a modification operation example (previous deformation) of the label support mechanism 2A' at the time of label conveyance. According to the deformation operation example of the label support mechanism 2A' shown in Fig. 61A, the label support mechanism 2A' at the distal end portion of the curved guide 30 shown in Fig. 60B is in contact with the label support shown in Fig. 7 The drive mechanism 9A is further actuated. When the label support mechanism 3A is further moved toward the package forming mechanism 6A, the front end portion of the curved guide 30 overcomes the biasing force of the coil spring portions 21 and 22 and abuts against the front end portion thereof. In the state, the direction toward the packing forming mechanism 6A is close.

At this point of time, the opening angle θ1 of the coil spring 21 and the opening angle θ2 of the coil spring member 22 change. In this example, the opening angle θ1 of the coil spring 21 that is pressed against the curved guide 30 is initially changed from θ1 = 90° to θ1 = 70°, and similarly, the opening angle θ2 of the coil spring member 22 is from the initial θ2. =230° changes to θ2=195° (previous deformation).

By the movement of the label holding mechanism 3A, the front end portion of the curved guide 30 abuts against the front end portions of the coil springs 21, 22 via the label 1A. In other words, the label 1A is sandwiched between the coil spring members 21 and 22 and the bending guide 30, and the label 1A can be prevented from coming off. Thereafter, in this state, the label 1A moves toward the installation space 92b (refer to Figs. 64, 48, and 49).

Fig. 61B is a top view showing a modification operation example (late deformation) of the label spring support mechanism 2A' at the time of label conveyance. According to the deformation operation example of the label spring support mechanism 2A' shown in Fig. 61B, the label holding drive mechanism 9A shown in Fig. 7 continues to operate, and the label holding mechanism 3A advances to reach the state of the package forming mechanism 6A. . In this state, the tag spring supporting mechanism 2A' abutting against the front end portion of the bending guide 30 shown in Fig. 61A is deformed. At this time, the front end portion of the bending guide 30 is stopped by the front end portion of the bending guide member 30 in a state where the front end portion thereof abuts against the biasing force of the coil spring members 21 and 22. At this point of time, it is conveyed toward the installation space 92b of the tag 1A (refer to Fig. 67).

Further, compared with the opening angle θ1 of the coil spring member 21 shown in Fig. 61A, the opening angle θ1 of the coil spring member 21 at the time of arrival changes again. Similarly, the opening angle θ2 of the coil spring member 22 at the time of arrival is changed again as compared with the opening angle θ2 of the coil spring member 22.

In this example, the opening angle θ1 of the coil spring member 21 that is pressed against the curved guide 30 is changed from the initial θ1 = 90° to θ1 = 20°, and similarly, the opening angle θ2 of the coil spring member 22 is from the initial stage. Θ2 = 230° changes to θ2 = 150° (late deformation).

Fig. 62 is a flow chart showing an operation example of the baler 200. Figs. 63 to 67 are partially enlarged perspective views showing an operation example of the label supporting mechanism 2A' at the time of carrying out the label conveyance.

In this example, the baler 200 includes the control unit 110 shown in FIG. 49, and the CPU 114 of the control unit 110 controls the label holding mechanism 3A, the label transport mechanism 4A, the package transport mechanism 5A, and the packing device. The case of the forming mechanism 6A, the packing device contracting mechanism 7A, and the label supporting drive mechanism 9 is taken as an example.

First, in step ST21, the CPU 114 detects whether or not the bag 14 is inserted. At this time, when the main switch 120 is turned on, it is detected that the bag 14 is inserted (refer to step ST1 of Fig. 50).

Next, in step ST22, the CPU 114 controls the transport mechanism 4A to pull the label 1A out of the cassette 40 and load it into the curved guide 30. In the standby state of the label holding mechanism 2A' and the label holding mechanism 3A, the label transport mechanism 4A is operated to pull the label 1A out of the cassette 40, and is held by the label hanging claw 30b of the curved guide 30. In this example, in the tag spring supporting mechanism 2A shown in Fig. 63, the movable leg portion 21b of the coil spring 21 and the movable leg portion 22b of the coil spring 22 and the curved guiding projection portion 30c of the bending guide 30 are The label 1A is filled in the gap. The front end of the label is fitted to the inner portion of the label supporting member 30e, and the mounting portion 11A is attached to the label hanging claw portion 30b.

Then, in step ST23, the CPU 114 controls the label holding drive mechanism 9A to carry the label holding mechanism 3A holding the label 1A toward the package forming mechanism 6A. At this time, according to the label spring supporting mechanism 2A' shown in Fig. 64, the label holding mechanism 3A which holds the label 1A with the curved guide 30 and the coil spring members 21, 22 shown in Fig. 63 becomes the bending. The front end portion of the guide 30 abuts against the front end portions of the coil spring members 21 and 22 via the label 1A. In other words, the state in which the coil springs 21 and 22 and the bending guide 30 sandwich the label 1A can prevent the label 1A from coming off.

Further, according to the label spring support mechanism 2A' shown in Fig. 65, the label holding mechanism 3A of the label 1A shown in Fig. 64 held by the curved guide 30 and the coil spring members 21, 22 is shown in Fig. 7. The label holding drive mechanism 9A generates an operation and advances in the direction of the package forming machine 6A (refer to Fig. 66). According to the label supporting mechanism 2A' shown in Fig. 66, the front end portion of the bending guide 30 is approached in the direction of the packing tool forming mechanism 6A with the front end portion abutting against the biasing force of the coil springs 21, 22.

Then, according to the label spring support mechanism 2A' shown in Fig. 67, the label spring support mechanism 2A' which abuts against the front end portion of the curved guide 30 shown in Fig. 65 continues by the label holding drive mechanism 9A. The action advances the label holding mechanism 3A to reach the package forming mechanism 6A. At this time, the front end portion of the bending guide 30 is stopped in front of the package forming mechanism 6A in a state of abutting against the front end portion thereof against the biasing force of the coil spring members 21 and 22. At this point of time, the conveyance to the installation space 92b of the label 1A is ended.

Thereafter, in step ST24, the CPU 114 controls the packer transport mechanism 5A, and while the packer 13 is pulled out from the spool 52, passes through the 11m of the label 1A and the package path 303 of the curved guide 30. (Refer to step ST8 of Fig. 50)

Next, in step ST25, the CPU 114 controls the package forming mechanism 6A to cut the package 13 and form it. (Refer to step ST9 of Fig. 50)

Then, in step ST26, the CPU 114 controls the packing implement contracting mechanism 7A, and the cut-away packing 13' passing through the label 1A is joined to the bag 14 and the hem (refer to step ST13 of Fig. 51).

Thereafter, in step ST27, the CPU 114 detects whether or not the bag 14 is discharged. At this time, by turning off the main switch, it is detected that the bag 14 is discharged (refer to step ST15 of Fig. 51).

Then, in step ST28, the CPU 114 determines whether or not it is finished. For example, the CPU 114 detects the OFF information of the main switch 120. When the OFF information of the main switch 120 is detected, the packing control is ended. When the power OFF information is detected, the process returns to step ST21, and the CPU 114 repeats the above processing, and controls the label holding mechanism 3A, the label transport mechanism 4A, the package transport mechanism 5A, the package forming mechanism 6A, the package contracting mechanism 7A, and The label holds the drive mechanism 9A.

Thus, according to the baler 200 as the second embodiment, the strip-shaped cut-away packing 13' is wound around the fold of the bag 14 by the two engaging holes 11m provided in the label 1, and the label 1A is mounted. When the label 1A is attached to the fold of the bag 14 when the label 1A is folded, when the label 1A is transferred from the label transport mechanism 4A to the package forming mechanism 6A via the label holding mechanism 3A, it is transported from the label transport mechanism 4A to the package. The side end portion of the label 1A having the molding mechanism 6 is press-fitted from both sides by a pair of coil spring members 21 and 22 provided in the body chassis portion 92.

Therefore, a highly reliable baler 200 is provided which assists in supporting the label supporting member 30e at the leading end of the label 1A when the label 1A is transferred from the label transport mechanism 4A to the package forming mechanism 6A via the label holding mechanism 3A. Thereby, when the short label 1A is operated compared with the normal length, it is possible to prevent the peeling caused by the label transmission error as compared with the case where the coil spring members 21 and 22 are not mounted. Therefore, the length of the label 1A is long or short, and the reproducibility of the label 1A from the label transport mechanism 4A to the package forming mechanism 6A can be performed.

Further, although the packaging device 13 is described with respect to the case where the twisted tape is coated on a core member such as a metal wire, the present invention is not limited thereto, and the present invention is also applicable to a coated wire having a slightly circular cross section as a packing device. 13 and use. Further, in the present invention, a wire which is not coated, a covered wire provided with a resin core wire, a wire member formed of only a resin, a belt member, or the like is used as the packing device 13.

[Industrial availability]

The present invention is applicable to a baler which is installed in a bag in which a snack or a wild vegetable is placed, and is packaged with a label indicating information such as a publicity document, a producer information, a conditioning recipe, and the like. Further, the present invention is also applicable to a baler which is attached to a bundled electric wire and which wraps a label which describes wiring information and the like. Moreover, the present invention is also applicable to a baler for packaging an identification label for agricultural fields such as dressing seedling cultivation.
