(Device configuration)
First, the structure of the packing apparatus which concerns on this embodiment is demonstrated, referring FIGS. 1-3. FIG. 1 is a schematic perspective view of the packing apparatus according to the first embodiment. FIG. 2 is a schematic side view of the packaging apparatus according to the first embodiment, and FIG. 3 is a schematic plan view of the packaging apparatus according to the first embodiment. The pressing cylinders 14a to 14d shown in FIG. 2 and FIG. 3 are not shown in FIG. 1 for the sake of explanation, and similarly the molding guides 12 and 12 are not shown for the sake of explanation in FIG.

  As shown in FIGS. 1 to 3, the packing device 1 packs the supply conveyor 3 for supplying the packing object 2 to the packing device 1 and the corrugated box 5 c in which the packing object 2 is packed and the flaps are folded. It is disposed between the delivery conveyor 11 and 11, the two forming guides 12 and 12, and the robot arm 13 (see FIGS. 2 and 3), which are disposed between the delivery conveyor 4 and the delivery conveyor 4 for receiving and discharging the apparatus 1. , A plurality of pressing cylinders 14a to 14d (see FIG. 2 and FIG. 3), and a lifting lift 15.

  The transport conveyor 11 extends in the transport direction X, is provided with a relatively movable belt along the circumferential direction, and cooperates to transport the object to be packed 2 by circumferentially moving the belt. In the orthogonal direction Y orthogonal to the transport direction X, they are disposed apart from each other by a constant distance. This separation distance may be set as appropriate depending on the type of the object to be packed 2 and the width of the supply conveyor 3 and the discharge conveyor 4, but it is preferable to set at least the distance at which the lifting lifter 15 can pass between the transfer conveyors 11.

  The molding guide 12 is for molding the corrugated cardboard sheet 5a into a rectangular cylindrical cardboard box 5b in an open state in which the flaps are not folded in, and a length of which the longitudinal direction is arranged along the orthogonal direction Y Flat plate member. The distance between the two molding guides 12, 12 is substantially the same as the length in the transport direction X of the cardboard box 5b. Further, a plurality of cardboard sheets 5a are placed on the side of the forming guide 12, and the end portions of the forming guide 12 on the side of the cardboard sheet 5a are gradually inclined in the direction of separating from each other.

  The robot arm 13 is disposed to face the cardboard sheet 5a, and is configured to be movable back and forth along the orthogonal direction Y. The robot arm 13 abuts on the cardboard sheet 5a at its tip and uses air suction or the like. A suction cup 132 capable of adsorbing this is provided. The corrugated board sheet 5a can be taken out by the robot arm 13, molded into a corrugated box 5b, and placed at a predetermined position.

  A method of molding the cardboard sheet 5a into the cardboard box 5b by the robot arm 13 and the molding guide 12 will be briefly described. First, the robot arm 13 advances toward the cardboard sheet 5a, and the suction cup 132 sucks a side panel (side wall to which the outer flaps are connected) of one cardboard sheet 5a. After suction, by retracting the robot arm 13, the side panel of the cardboard sheet 5a is inserted between the forming guides 12, and the back panel adjacent to this (the side wall to which the inner flap is connected) contacts the forming guide 12 Do. By continuously retracting the robot arm 13 in this state, the corrugated sheet 5a can be gradually deformed into a box shape along the inclination of the end of the forming guide 12, and can be formed into the corrugated box 5b. .

  The pressing cylinders 14a to 14d are provided at a cylinder case 142, a piston rod 144 one end of which is accommodated in the cylinder case 142 so as to be able to reciprocate, and the other end of the piston rod 144 and extends in a lateral direction (horizontal direction). And a rectangular flat-shaped pressing portion 146 existing. The two pressing cylinders 14a and 14a are provided to face the upper inner surface flaps 52a of the cardboard box 5b disposed at the predetermined positions, and the two pressing cylinders 14b and 14b are provided to face the upper outer surface flap 52b. It is provided. Similarly, the two pressing cylinders 14c and 14c are provided above the pressing cylinders 14a and 14a so as to respectively face the flaps 52c in the bottom of the cardboard box 5b, and the two pressing cylinders 14d and 14d are disposed on the bottom outside flap 52d respectively. It is provided above the pressing cylinders 14 b and 14 b so as to face each other. The pressing portion 146 is preferably made of a resilient material so as not to damage the cardboard box 5b.

  By advancing each piston rod 144 of the pressing cylinders 14a to 14d, the pressing portion 146 can abut against and push in the opposing flaps, and the flaps can be folded into the inside of the cardboard box 5b. In order to realize the folding of the flap well, the pressing cylinders 14a to 14d have the axial center of the piston rod 144 inclined upward or downward at a predetermined angle (for example, 45 °) with respect to the flap surface. It is preferable to arrange it so that

  Here, the packaging box in the present embodiment, that is, the corrugated sheet 5a shown in FIG. 1, and the flaps on the bottom side of the corrugated box 5b, 5c (inside flap 52c, outboard flap 52d) in the longitudinal direction (lateral direction) A ruled line 54 is provided along the line. Hereinafter, with the ruled line 54, the connection side with the side wall of the cardboard box, that is, the side serving as the fulcrum for opening the flap is referred to as one end side piece 522d, and the other side is the other end side piece It is called 524d. The pressing cylinder 14d according to the present embodiment is configured to bend the other end side piece 524d of the bottom outer flap 52d with respect to the one end side piece 522d. The ruled line 54 serves as a fulcrum when bending the other end side portion 524 d of the bottom outer flap 52 d, and is provided to facilitate the bending. Specifically, the pressing cylinder 14d bends the other end side piece 524d of the bottom outer flap 52d, and is arranged to be able to press the ruled line 54 or its vicinity in order to engage this with the contact piece 154 described later. It will be set up.

  In the present embodiment, the creases 54 are notches and are formed on the front or back of the bottom outer flap 52 d. In particular, by forming on the back surface, bending of the other end side piece portion 524d of the bottom outside flap 52d becomes easy. In addition, as a cut | notch, for example, the front liner or back liner which comprises a corrugated-cardboard is cut | disconnected with a core together, and it is mentioned as only any liner, and you may make it leave a core depending on the case. The ruled line 54 is not a cut but may be a process such as a broken line (slit) in which holes are arranged in a line, or the like so as to facilitate bending of the other end side portion 524d of the bottom outside flap 52d.

  The lifting lifter 15 is disposed below the transport conveyor 11, and is movable up and down so as to be able to pass between the transport conveyors 11 and inserted into and removed from the cardboard box 5b by a driving device (not shown) A pedestal 152 is provided, and the support pedestal 152 is provided with a contact piece 154.

  The support base 152 is a flat plate member that abuts on the object to be packaged 2 to support it, and is connected to a piston rod extending downward to be able to move up and down. The size of the support base 152 may be a size that can be inserted into the cardboard box 5b, but the length in the transport direction X is that even if the pair of bottom inner flaps 52c, 52c of the cardboard box 5b are folded in Since it is necessary to pass between the tips, that is, between the tips of the in-bottom flaps 52c, 52c, it is preferable to set the tips to the same distance or less. In addition, the length in the orthogonal direction Y is preferably equal to or less than the length between one end side piece portion 522d or the other end side piece portion 524d of the bottom outside flap 52d folded on the bottom inside flap 52c.

  The contact pieces 154 are respectively provided at the corner portions of the support base 152, and have an L shape in which the protrusions 156 are formed so as to protrude in the direction away from each other in the orthogonal direction Y. With this shape, when the lifting lifter 15 inserts the object to be packed 2 into the cardboard box 5b, the contact piece 154 and the other end side piece 524d when the bottom outer flap 52d is folded inward It can abut. As a result of this abutment, the bottom outer flap 52d is folded outward (downward) at the border of the ruled line 54 and engaged with the abutment piece 154 in a hooked manner.

  The engagement between the contact piece 154 and the bottom outer flap 52d allows the contact piece 154 to support the cardboard box 5b, whereby the cardboard in a state in which the respective flaps are folded in accordance with the lowering of the lifting lifter 15. The box 5 c can be placed on the transport conveyor 11. From this, it is preferable that the vertical length of the contact piece 154 be configured to be extensible according to the size of the cardboard, in particular, the size of the bottom outer flap 52 d and the position of the ruled line 54.

(Device operation)
Next, the packing method of the packing apparatus which concerns on this embodiment is demonstrated in detail using FIGS. 4-12. In FIG. 5, the molding guides 12 are not shown for the sake of explanation.

  First, as shown in FIG. 4, the cardboard box 5 b is disposed at a predetermined position by the robot arm 13, and is transported by the transport conveyor 11 so that the object to be packed 2 is positioned directly below the cardboard box 5 b. In this state, as shown in FIG. 5, the lift lifter 15 ascends to insert the object to be packed 2 into the cardboard box 5b. At this time, it is preferable to arrange the object to be packed 2 substantially at the center of the cardboard box 5b so that each flap can be folded. After arranging the object to be packed 2, as shown in FIG. 6, the inner bottom flaps 52c, 52c are respectively folded inward by the pressing cylinders 14c, 14c. FIG. 7 shows the state after this folding, as viewed from the cross section B-B shown in FIG. In addition, it is preferable to maintain the press to the bottom inner surface flap 52c by the press cylinder 14c until the press of the bottom outer flap 52d mentioned later is started here.

  After the bottom bottom flap 52c is folded, as shown in FIG. 8, the bottom bottom flaps 52d and 52d are respectively folded inward by the pressing cylinders 14b and 14d. At this time, in the present embodiment, as described above, the creased line 54 is provided on the bottom outer flap 52 d, and the contact piece 154 is further provided on the support base 152. Therefore, when the bottom outer flap 52d is folded inward, the other end side piece 524d abuts on the contact piece 154, is bent at the border of the ruled line 54, and is folded outward (downward). As a result, the other end-side piece 524 d of the bottom outer flap 52 d located below the ruled line 54 abuts on the abutting piece 154 and its tip end engages with the projection 156 of the abutting piece 154. Therefore, the bottom outer flap 52d and the cardboard box 5b are supported by the contact piece 154. Further, this engagement defines an opening 56 communicating with the inside of the cardboard box 5b in which the other end side portion 524d of the bottom outer flap 52d is separated by a predetermined distance, in other words, the lifting lifter 15 can pass through. It will be

  In this manner, in the state where the bottom outer flap 52d is folded, even if the bottom inner flap 52c tries to return to the original position (upward) by its elastic force, it abuts on the bottom outer flap 52d, thereby preventing the return. can do. Therefore, when the pressure is applied to the flap 52c on the bottom surface by the pressure cylinder 14c, the pressure is released here. After the bottom outer flap 52d is folded in, the suction by the suction cup 132 is released and the robot arm 13 is withdrawn. At this time, since the cardboard box 5b is supported by the contact piece 154, it does not fall off.

  After the robot arm 13 is withdrawn, the lifting lifter 15 is lowered to lower the cardboard box 5b together with the object to be packed 2 and place them on the transport conveyor 11 as shown in FIG. At this time, since the one end-side piece 522d of the bottom-surface outside flap 52d is folded on the bottom-surface inside flap 52c, only the one-end-side piece 522d of the bottom outside flap 52d can be brought into contact with the transport conveyor 11. Since the object to be packed 2 is not exposed above the transfer conveyor 11, these contacts can be prevented. In addition to this, the other end side portion 524d of the bottom outside flap 52d is folded back so as to cover the transfer conveyor 11 as viewed from the object to be packed 2, so the contact between the object 2 to be packed and the transfer conveyor 11 The effect of preventing Further, since the bottom outer flap 52d is separated by a predetermined distance between the other end side pieces 524d by the contact piece 154, as shown in this figure, the lifting lifter 15 passes the opening 56 from the cardboard box 5c. You can get out and retreat further downward.

  After leaving the lifting lifter 15, as shown in FIG. 10, the upper surface inner flaps 52a, 52a are respectively folded inward by the pressing cylinders 14a, 14a, and then the upper surface outer flaps 52b, 52b, as shown in FIG. Fold 52b inward. Here, in the present embodiment, the pressing state of the upper outer flap 52b by the pressing cylinder 14b is maintained. This is to prevent the return (opening) to the original position due to the elastic force of the upper surface outer flap 52b. By doing so, the top outer flap 52b can be made flat, so that tape sticking can be performed extremely well by using an existing tape sticking apparatus (not shown) disposed at a later stage. It is preferable to provide a roller rotatable in the conveying direction X at the end of the pressing portion 146 of the pressing cylinder 14b, since a mark may be left on the upper surface outside flap 52b if it is transported in the pressed state. In the case where the cardboard box 5c does not return the flap 52b on the upper surface, or in the case where another roller is provided to flatten the flap 52b on the upper surface, this pressure state is naturally released. It is also good.

  Here, since there is no contact piece 154 that inhibits the mutual approach, the other end side piece 524d of the bottom outer flap 52d is returned to the original position to some extent upward (inner side) by its elastic force and brought into proximity It becomes. Therefore, the bottom outer flap 52d can be fixed by the tape by conveying it to the tape bonding apparatus as it is. On the other hand, as shown in FIG. 12, the lifting lifter 15 may be raised again, and the bottom outer flap 52d may be closed using the support base 152. In this way, the bottom outer flap 52d is made flat. The tape can be attached very well.

  According to the present embodiment, after the packing object 2 is accommodated in the cardboard box 5c, the cardboard box 5b is placed on the transport conveyor 11 so that the one end side piece 522d of the bottom outer flap 52d abuts on the transport conveyor 11. Since it can mount, the contact with the packing target object 2 and the conveyance conveyor 11 can be prevented, and damage to the packing target object 2 can be reduced. Further, since the other end side piece portion 524d is folded back to the outside, the opening 56 can be defined between the other end side piece portions 524d of the bottom outer flap 52d, and the lifting lifter 15 is well retracted from the inside of the cardboard box 5b. It can be done.

  In addition, since the cardboard box 5b can be placed on the transport conveyor 11 in a state in which the one end-side piece 522d of the bottom outside flap 52d is folded on the bottom inside flap 52c, the vertical direction of the object 2 to be packed from the conveyor The height can be made higher than before, and the contact between the object to be packed 2 and the transport conveyor 11 can be prevented more reliably.

  In addition, after the lifting lifter 15 retreats, the other end-side piece 524d of the bottom external flap 52d returns to its original position to some extent by its elastic force, so that the tape application of the bottom external flap 52d can also be performed in that state. it can. Therefore, it is possible to eliminate the need for the guide bar for closing the existing bottom outer flap and the bottom guide for the same, and to realize the reduction of the manufacturing line and the reduction of the cost of parts.

Second Embodiment

  In the first embodiment described above, the packing apparatus for putting the packing object into the packing box from the lower side has been described, but the packing object may be put into the packing box from the top. Hereinafter, as a second embodiment, a packing apparatus for putting a packing object into the packing box from above will be described.

  In the present embodiment, a description will be given by taking an example of a packing apparatus for packing a sheet-like object in which BIB sheets used in a BIB (back in box) are connected as a packing object. In the present specification and the drawings, components having substantially the same functional configuration will be assigned the same reference numerals and redundant description will be omitted.

(Device configuration)
First, the configuration of the packing apparatus according to the present embodiment will be described with reference to FIG. As shown in FIG. 1, the packing apparatus 1 ′ conveys the packing object 2 ′ and can move forward and backward, a pair of support plates 17 and 17 supporting the cardboard box 5d, and the inside of the cardboard box 5d. And a lifting bar 15 for placing the packing object 2 'and a transport bar 18 for transporting the cardboard box 5d. On the downstream side of the packing device 1 ′, there is disposed a discharge conveyor 4 for receiving from the packing device 1 ′ a cardboard box 5c in a state where the packing object 2 ′ is packed and the flaps are folded. There is. In addition, 22 shown by FIG. 13 is a spout (spout).

  The advancing / retracting conveyor 16 is provided with a relatively movable belt along its circumferential direction, and is moved downstream by circulating the belt around the object to be packed 2 'placed by a feeder or operator (not shown) upstream. Is transported on the lifting lifter 15 disposed in FIG. The advancing and retracting conveyor 16 is configured to reciprocate back and forth along the conveying direction X, and when it moves along the conveying direction X (hereinafter referred to as advancing), it is positioned on the lifting lifter 15 and packaged The object 2 ′ can be placed on the lift lifter 15. Such things include, for example, a shuttle conveyor.

  The support plate 17 extends in the transport direction X so that the downstream side approaches the discharge conveyor 4 and is disposed apart from each other by a predetermined distance in the orthogonal direction Y orthogonal to the transport direction X horizontally. Can be placed on it. This separation distance may be appropriately set according to the type of the packing object 2 'and the width of the advancing / retracting conveyor 16, the discharge conveyor 4, etc. However, it is preferable to set at least the distance that the lifting lifter 15 can pass between the support plates 17. .

  Here, in the present embodiment, each flap of the upper surface of the cardboard box 5d is opened, and the bottom outer flap 52d is folded so as to cover the bottom inner flap 52c in a folded state and placed on the support plate 17 It is placed. As in the first embodiment, the bottom outer flap 52d is provided with a ruled line 54 along the longitudinal direction (lateral direction), and one end side piece 522d and the other end side piece 524d are formed. Each of the one end side pieces 522d of each bottom outer flap 52d is in contact with the corresponding support plate 17, and each of the other end side pieces 524d is located downward between the pair of support plates 17, 17. It is in the state of being folded back. Therefore, an opening (space) 56 is defined between the other end side pieces 524d, through which the support base 152 of the lifting lift 15 can be inserted, which communicates with the inside of the cardboard box 5d. From the above, the state of the cardboard box 5d is the state shown in FIG. 9 in the first embodiment.

  In the present embodiment, the support plate 17 is configured to be movable in a direction to approach each other in order to fold the other end side portion 524d of the bottom outer flap 52d into a flat state, that is, close the opening 56. There is. In order to place the cardboard box 5d in a state where the other end side piece 524d is folded back to the outside, the separation distance of the support plate 17 needs to be larger than the distance between the ruled lines 54. Further, it is preferable that the support plate 17 be movable in directions away from each other so as to correspond to various sizes of cardboard boxes 5d.

  The lifting lifter 15 is disposed below the approximate center between the support plates 17 and 17 and is positioned between the other end side portions 524d of the bottom outside flap 52d which is positioned between the support plates 17 and 17 by a drive device (not shown). It can be passed up and down through the formed opening 56 and inserted into and removed from the cardboard box 5d. The specific configuration is the same as that of the first embodiment, and thus the detailed description is omitted.

  In the present embodiment, in a state where the support base 152 is positioned in the cardboard box 5d, the floor plate 158 of a predetermined size is placed thereon, and the object to be packed 2 'is placed on the floor plate 158 . The size of the floor plate 158 is such that it can enter into the cardboard box 5d from above and can not pass through the opening 56. Therefore, when the lifting lifter 15 retreats downward, the floor plate 158 is placed on the floor plate 158 Only the packing object 2 'will remain in the cardboard box 5d.

  The transport bar 18 is configured to reciprocate back and forth along the transport direction X. The object to be packed 2 'is accommodated in the cardboard box 5d, and the other end 524d of the bottom outer flap 52d is folded. After or when all the flaps are folded, the cardboard box 5d is conveyed to the discharge conveyor 4.
