Abstract

A tag tape (2t) which is fed out from a tag tape original fabric (2r) is cut to a tag (2) of prescribed length by a cutter (211). The tag (2) which is cut is supplied to a rotating tag transfer drum (22) from the cutter (211) at a prescribed interval, and it is shifted from the tag transfer drum (22) to a peripheral face of a rotary supporter (10). Thus, the rotary supporter (10) is made to support the tag (2) at the prescribed interval. The cutter (211) is slidably held by a frame (212) and the frame (212) is rocked with a rotation axis of the tag transfer drum (22) as a center. Fluctuation of tensile force of the tag tape (2t) between the tag tape original fabric (2r) and the cutter (211) is suppressed by a dancer mechanism (250) and a path length adjusting link mechanism (260). For supplying the tag obtained by cutting the tag tape by the cutter to the rotary supporter and manufacturing a sheet for extraction bag, fluctuation of tensile force of the tag tape (2t) with intermittent transmission of the tag to the cutter is reduced and tag supply speed to the rotary supporter is made fast.

Description

[Name of invention determined by ISA based on Rule 37.2] Tag supply method and supply device

The present invention relates to a yarn hooking device used for manufacturing a sheet for an extraction bag and a machine for manufacturing a sheet for an extraction bag using the yarn hooking device.

As a tea bag for tea, green tea, herbs, etc., as a bag for extracting dried stock such as dried and dried bonito, a water-permeable filterable sheet such as non-woven fabric is formed into a flat bag shape, tetrahedron shape bag body, etc. What is used is filled with extraction materials such as tea leaves and attached with a hanging thread with a tag on the outer surface.

However, as the tag is cut from the tag tape, the feed of the tag tape to the cutter becomes intermittent, which limits the speed of supplying the tag to the rotating carrier, and hence the extraction bag. It has also been difficult to improve the production speed of the sheet for the machine.

On the other hand, the present invention cuts the tag from the tag tape and improves the processing speed in the tag supplying process in which the tag is supported on the rotating carrier at a predetermined interval, and consequently the production speed of the extraction bag sheet is increased.

If a dancer mechanism and a link mechanism are provided in the path path of the tag tape, and the length of each link and the position of the link fulcrum are appropriately arranged, the path length of the tag tape varies with intermittent feeding of the tag tape. In spite of this, it has been found that the tension fluctuation of the tag tape can be suppressed while suppressing the fluctuation of the position of the dancer roll in the dancer mechanism, thereby achieving the above-mentioned object.

That is, the present invention cuts the tag tape fed out from the original tag tape into a tag having a predetermined length with a cutter, and supplies the cut tag to the rotating tag delivery drum from the cutter at predetermined intervals.

Further, as a machine for carrying out the above-described method for producing an extraction bag sheet, an extraction bag sheet producing machine in which tags bonded to a thread material are arranged at predetermined intervals in the longitudinal direction of the water-permeable filterable sheet. And
(1) A tag cut supply device for cutting a tag tape fed out from a tag tape raw material into a tag having a predetermined length with a cutter, and supplying the cut tag from the cutter to a rotating tag delivery drum at a predetermined interval; and A tag supply device for supporting a tag on the rotation carrier at predetermined intervals by providing a tag delivery drum for transferring the tag supplied from the tag cut supply device to the peripheral surface of the rotation carrier

According to the tag supply method or the tag supply device of the present invention, a cutter that cuts a tag having a predetermined length from a tag tape and supplies it to the tag delivery drum swings around the rotation axis of the tag delivery drum. Therefore, the cutter can be moved along the rotating peripheral surface of the tag delivery drum. Therefore, delivery from the tag cutter cut from the tag tape to the tag delivery drum can be performed smoothly.

Furthermore, since the variation in the tension of the tag tape between the original tape and the cutter is suppressed by the dancer mechanism and the path length adjusting link mechanism, the path length of the tag tape varies with intermittent feeding of the tag tape to the cutter. Nevertheless, the tension fluctuation of the tag tape can be suppressed while suppressing the fluctuation of the position of the dancer roll in the dancer mechanism as much as possible. Accordingly, it is possible to feed the tag tape from the original tag tape at a substantially constant speed, thereby increasing the supply speed of the tag tape and improving the production speed of the extraction bag sheet.

Hereinafter, the present invention will be specifically described with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.

FIG. 1 is a configuration diagram of an embodiment of a tag supply device 20 that performs the tag supply method of the present invention, and FIG. 2 is a configuration diagram of an extraction bag sheet manufacturing machine 1 incorporating the tag supply device 20. is there.

The extraction bag sheet manufacturing machine 1 generally includes a tag supply device 20 according to this embodiment for supplying a tag 2 to a peripheral surface of a rotary carrier 10 rotating in the direction of an arrow at a predetermined interval, a yarn hooking mechanism 40, and a rotary carrier. A sheet supply device 50 for supplying the water-permeable filterable sheet 4 onto the tag 2 and the thread material 3 on the body 10; adhesion between the tag 2 and the thread material 3; adhesion between the tag 2 and the water-permeable filterable sheet 4; Or it consists of the sealing device 60 which adhere | attaches the thread material 3 and the water-permeable filter sheet 4. FIG.

Further, downstream of the extraction bag sheet manufacturing machine 1, the extraction bag sheet 5 manufactured by the extraction bag sheet manufacturing machine 1 is used to make a bag in a pyramid shape, and the contents such as tea leaves are contained therein. A filling and packaging machine 70 for filling the product to produce the extraction bag 6 is provided.

The tag supply device 20 includes a tag cut supply device 21 and a tag delivery drum 22. The tag cut supply device 21 intermittently feeds the tag tape 2t fed out from the tag tape raw material 2r to a so-called guillotine cutter 211 by a tag pitch feed driving roller 210 controlled by a motor and a nip roller facing the tag tape feed roller 210. In 211, the tag 2 is cut into a predetermined length, and the cut tag 2 is projected from the cutter 211 to the tag delivery drum 22 rotating at a constant speed in the direction of the arrow, and supplied to the tag delivery drum 22 at predetermined intervals. Further, the tag delivery drum 22 sucks and holds the tag 2 supplied from the tag cut supply device 21 on its surface, and transfers it to the peripheral surface of the rotary carrier 10. Note that a mechanism for sucking and holding the tag 2 by switching the suction path by a rotary bubble is provided on the peripheral surface of the rotary carrier 10.

Here, the cutter 211 is held by the frame 212 of the tag cut supply device 21 so as to be slidable in the radial direction of the tag delivery drum 22. The frame 212 can swing around the rotation axis P1 of the tag delivery drum 22. Therefore, the cutter 211 can move along the circumferential surface of the tag delivery drum 22 while the tag 2 is cut from the tag tape 2t and the cut tag 2 is supplied to the tag delivery drum 22. Therefore, it becomes possible to smoothly deliver the cut tag 2 from the cutter 211 to the tag delivery drum 22.

Such movement of the cutter 211 can be formed by the following crank and cam mechanism. That is, the frame 212 of the tag cut supply device 21 can swing around the rotation axis P <b> 1 of the tag delivery drum 22.

Also, one end of an arm 220 is fixed to a tag cut supply device swing drive crankshaft P2 rotatably attached to the body of the extraction bag sheet manufacturing machine 1, and a rod 221 is connected to the other end. The end portion is rotatably joined to the frame 212 of the tag cut supply device by a joining portion 213. An arm 222 driven by a cam 230 is also fixed to the tag cut supply device swing drive crankshaft P2.

On the other hand, a cutter drive crankshaft P3 is rotatably attached to the body of the extraction bag sheet manufacturing machine 1, one end of an arm 240 is fixed to the cutter drive crankshaft P3, and a rod 241 is connected to the other end. In addition, the end portion of the rod 241 is rotatably joined to the base material of the cutter 211 by the joining portion 214. An arm 242 driven by a cam 231 is also fixed to the cutter drive crankshaft P3.

Here, these cams 230 and 231 are integrally formed, and both rotate in the direction of the arrow b around a shaft P4 rotatably attached to the main body of the extraction bag sheet manufacturing machine 1. Therefore, the tag cut supply device swing drive crankshaft P2 is rotated by the follow of the arm 222 accompanying the rotation of the cam 230, and the arm 220 fixed to the shaft P2 swings around the shaft P2, thereby the rod A joint portion 213 between 221 and the frame 212 swings about the axis P1. Further, the cutter drive crankshaft P3 is rotated by the follower of the arm 242 accompanying the rotation of the cam 231, and the arm 240 fixed to the shaft P3 swings around the axis P3, whereby the cutter 211 is moved to the tag delivery drum. 22 in the radial direction.
In this way, the cutter 211 can take the locus of the arrow a.

In the extraction bag sheet manufacturing machine 1, between the tag supply device 20, that is, between the tag tape original fabric 2r and the cutter 211, a dancer mechanism 250 and a path length for suppressing the tension fluctuation of the tag tape 2t during this period. An adjustment link mechanism 260 is provided.

In the dancer mechanism 250, the rotation speed of the driving roller 253 for feeding the tag tape 2t is controlled by the servo motor 255 based on the angle detector 254 attached to the arm fulcrum shaft of the dancer roller 251.

Further, the path length adjusting link mechanism 260 is such that a rotatable joint 265 between the ends of the two bar links 262 and 264 is a fulcrum shaft of the guide roller 266 of the tag tape 2t. The other end of one bar link 262 has a fulcrum shaft 261 on the frame 212, and this fulcrum shaft 261 is also a fulcrum shaft of the guide roller. The other end of the other bar link 264 has a fulcrum shaft 263 on the mounting base of the frame 212 (the main body of the extraction bag sheet manufacturing machine 1).

According to this path length adjusting link mechanism 260, the tension associated with intermittent feeding of the tag tape 2t to the cutter 211 is set by appropriately setting the lengths of the bar links 262 and 264 and the positions of the fulcrum shafts 261 and 263. The fluctuation can be remarkably reduced, and the position fluctuation of the dancer roller 251 of the dancer mechanism 250 can be remarkably suppressed.

For example, in the tag supply device 20 of FIG. 1, the path length adjustment link mechanism 260 is not provided, and the center of the guide roller 266 is fixed to the main body of the extraction bag sheet manufacturing machine 1 as shown in FIG. When the tag tape 2t is intermittently sent to the cutter 211, the guide rollers 266 and 267 are arranged as shown in FIG. 3A when the variation amount of the position of the dancer roller 251 is about 70 mm. (C) is provided with a path length adjustment link mechanism 260, the length of the bar link 262 is 110 mm, the length of the bar link 264 is 60 mm, the diameter of the guide rollers 266 and 267 is 25 mm, and By changing the position of the fulcrum shaft 263 of the bar link 264 from the center of the guide roller 267 to the fulcrum shaft 261 side of the other bar link 262, the fluctuation amount of the dancer roller 251 is about 5 mm. Can be reduced to Further, as shown in FIG. 3B, when the same path length adjusting link mechanism 260 is provided and the fulcrum shaft 263 of the bar link 264 is overlapped with the center of the guide roller 267, the dancer roller 251 The fluctuation amount can be reduced to about 17 mm.

On the other hand, in this manufacturing machine 1, the rotation carrier 10 is continuously rotated in the direction of the arrow by a servo motor while the manufacturing machine 1 is in operation (FIG. 2).

The outer periphery of the rotary carrier 10 is divided into 24 parts, and two placement parts for the tag 2 are provided close to each divided area. At the place where the tag 2 is placed, the suction of the tag 2 is started from the position facing the tag supply device 20, and the tag 2 and the water-permeable filter sheet 4 are weakly sealed as described later (fourth seal). The vacuum pump or blower motor sucks and holds the tag 2 by switching the suction path using the rotary bubble so that the suction is cut from the device 64) until before the extraction bag sheet is separated from the peripheral surface of the rotary carrier 10. A mechanism is provided.

Further, the rotary carrier 10 is provided with a vertical mechanism for the pin 11 for thread hooking. In this up-and-down mechanism, the pin 11 is always urged by a spring so as to protrude from the peripheral surface of the rotary carrier, but in the region where the water-permeable filter sheet 4 is supplied to the peripheral surface of the rotary carrier 10. Then, it is lowered toward the inside of the rotary carrier along the shape of the fixed cam provided inside the rotary carrier 10 so that the amount of protrusion from the peripheral surface of the pin 11 is small.

The yarn hooking mechanism 40 forms a continuous rotation pattern of the thread material 3 on the peripheral surface of the rotary carrier 10 in which the tags 2 are arranged at predetermined intervals while adjusting the tension of the thread material 3 to be substantially constant. There is a drive roller 401 for feeding the yarn material 3 from the yarn material stock 3r, a nip roller 402 facing it, a tension adjusting means 410 for the yarn material 3, and a continuous rotation pattern of the yarn material 3 on the peripheral surface of the rotary carrier 10. The tension adjusting means 410 includes a dancer mechanism 420 and a path length adjusting device 430 downstream thereof.

As shown in FIG. 4, the yarn hooking device 30 includes a first drive crank mechanism 32 a and a second drive crank mechanism 32 b connected in a substantially orthogonal direction by a joint portion 31. These drive crank mechanisms 32a and 32b include crank arms 34a and 34b driven by servo motors 33Ma and 33Mb, respectively, and links 35a and 35b connected to the crank arms 34a and 34b. The first drive crank mechanism 32a and The joint portion 31 of the second drive crank mechanism 32b connects the intermediate portion of the link of the first drive crank mechanism 32a and the tip portion of the link of the second drive crank mechanism 32b. Further, a threading holding bracket 38 provided with a ring-shaped thread guide 36 and a threading 37 is provided at the tip of the link 35a of the first drive crank mechanism 32a.

As described above, when the joint portion 31 of the first drive crank mechanism 32a and the second drive crank mechanism 32b is provided at the intermediate portion of the link of the first drive crank mechanism 32a, the joint portion 31 and the crank arm 34b are linked. It is possible to prevent the sliding portion serving as a dust generation source such as a joint portion with 35b from being positioned on the peripheral surface of the rotation carrier 10. Further, since the threading holding bracket 38 is only positioned on the peripheral surface of the rotary carrier 10 and the link is located outside the peripheral surface, the thread-passing sheet or the water-permeable filterable sheet is placed on the rotary carrier 10. It is possible to eliminate as much as possible any obstacles during supply.

Further, according to the yarn hooking device 30, the threading holding bracket 38 is driven by the two drive crank mechanisms 32a and 32b, and the servo motors 33Ma and 33Mb are used as the drive sources of the drive crank mechanisms 32a and 32b, respectively. Therefore, it is possible to move the threader 37 on the track required for threading.

Specifically, for example, as shown in FIG. 5, when the two tags 2 are arranged at predetermined intervals so as to be close to the peripheral surface of the rotation carrier 10 and are fixed by suction, In order to form a continuous pattern in which the material 3 is stretched in the axial direction of the rotary carrier on each tag 2, as shown in FIG. 6, when threading, the threading pins 11 a and 11 b are connected to the tags 2. At both sides (the upstream side and the downstream side in the rotation direction of the rotation carrier 10), the rotation carrier 10 is protruded to a position near one peripheral edge 10 a and at a position away from each tag 2 in the axial direction of the rotation carrier 10. Further, the thread hooking pins 11c and 11d are protruded, and the threading 37 at the tip of the threading holding bracket 38 has a predetermined radius (for example, 6 to 10 mm) around these pins 11 (11a, 11b, 11c and 11d). ), 11 and 1 It should be moved a threading device 30 as during the travel on the tangent of the above-mentioned circular orbit. 5 and 6, the broken line indicates the water-permeable filter sheet 4 to be supplied to the peripheral surface of the rotary carrier 10 later, and the dotted line indicates the region of one extraction bag in the water-permeable filter sheet 4. Indicates a separator. Further, in FIG. 6, the continuous rotation pattern of the thin line corresponds to the continuous rotation pattern of FIG.

Here, the trajectory La in FIG. 6 is a trajectory with respect to the pin 11 moving in the direction of the arrow due to the rotation of the rotary carrier 10, so that the threading 37 is fixed to the trajectory Lb shown in FIG. The threading device 30 is moved so as to draw In addition, the code | symbol P1 in FIG. 6 and FIG. 7 has shown the corresponding point on these track | orbits La and Lb.

Such movement of the threader 37 can be obtained by causing the servo motors 33Ma and 33Mb to reciprocate and controlling the rotation speed and rotation time thereof. In this case, the range of the swing angles θa, θb of the crank arms 34a, 34b is preferably set to 120 degrees or less. When the crank arms 34a and 34b are close to the top dead center or the bottom dead center, the movement of the links 35a and 35b becomes smaller than the movement of the crank arms 34a and 34b, and the threader 37 can be moved at an intended speed. Although it becomes difficult, by moving the crank arms 34a and 34b within the above-described range, the threader 37 can be moved at an intended speed.

Further, when the movement of the threading 37 is controlled by the servo motors 33Ma and 33Mb, (i) the traveling speed of the threading 37 is controlled to be constant, and (ii) the threading 37 is around the pin 11. The speed of the threading 37 is controlled based on a predetermined deformation curve. (Iii) Acceleration and deceleration of the threading 37 are performed based on a predetermined deformation curve. (iv) A mode in which the feeding speed of the thread material 3 from the thread material original fabric 3r around which the thread material 3 is wound can be set at a constant speed can be taken. To (iv).

Note that such movement of the yarn hooking device 30 can be controlled by operating a servo mechanism with a rotary encoder attached to the servo motors 33Ma and 33Mb.

The sheet supply device 50 unwinds the water-permeable filterable sheet 4 from the sheet raw material 4r around which the water-permeable filterable sheet 4 is wound, and the water-permeable filterable sheet 4 is supported on the rotation carrier 10 at a predetermined interval. It supplies so that it may place on the continuous pattern of the tag 2 and the thread material 3 formed on the tag 2. Here, the water-filterable sheet 4 can be fed out by controlling the feed-out speed with the nip drive roller 52 that feeds the water-filterable sheet 4 with an angle detector attached to the dancer roller 51 in the middle of the path. It is adjusted as fast as possible.

As the sealing device 60, before supplying the water-permeable filterable sheet 4 onto the rotation carrier 10, the tag 2 and the thread material 3 carried on the rotation carrier 10 are sealed as shown in FIG. After supplying the water-permeable filterable sheet 4 onto the first sealing device 61 and the rotary carrier 10 that are strongly sealed at s1, as shown in FIG. 8 (b), in the region for each extraction bag, the tag 2, a second sealing device 62 that strongly seals the thread material 3 and the water-permeable filter sheet 4 at a portion s2 that is separated in the longitudinal direction of the water-filterable sheet 4 from the tag 2 as shown in FIG. A third sealing device that weakly seals the yarn material 3 and the water-permeable filter sheet 4 at a portion s3 where the yarn material 3 is extended in the axial direction of the rotary carrier 10 from the side, that is, the width direction of the water-permeable filter sheet 4 63, the tag 2 and the water-permeable filter sheet 4 are attached at the seal part s4 shown in FIG. And a fourth sealing device 64 for sealing. Here, the strong seal means that the seal part is firmly sealed to the extent that the seal part does not peel off when the normal extraction bag is used, and the weak seal means that the seal part is easily peeled off when the extraction bag is used. To seal as weakly as possible. Further, in the figure, hatching frames surrounding the seal portions s1, s2, s3, and s4 indicate regions where the seal head is applied.

In addition, in the manufacturing machine 1 of the sheet for extraction bags of the present invention, the seal part can be appropriately changed according to the rotation pattern of the thread material 3, the arrangement of the pins 11, and the like. For example, the strong seal portion s2 between the thread material 3 and the water-permeable filter sheet 4 is equivalent to one extraction bag from the boundary region of one extraction bag as shown by s2 'shown by a broken line in FIG. You may shift to the center side of an area | region. Moreover, you may serve as the seal | sticker site | part s2 of the boundary area | region for every extraction bag by the width direction seal | sticker of the water-permeable filter sheet 4 at the time of bag making. However, by tightly sealing the thread material 3 and the water-permeable filterable sheet 4 at the seal portion s2 before bag making, the thread that becomes a hanging thread on the water-permeable filterable sheet 4 constituting the bag body in the extraction bag. This is preferable because the material 3 can be securely bonded.

The sealing means in these sealing devices 60 (61, 62, 63, 64) may be ultrasonic welding or heat welding. However, ultrasonic welding is advantageous in that the sheet melt does not adhere to the sealing device. preferable.

Further, these sealing devices 60 are preferably moved up and down with respect to the peripheral surface of the rotation carrier 10 by using a servo motor as a drive source separately from the drive source of the rotation carrier 10. It is preferable to make it swing as shown by the arrow shown in FIG. As a result, the contact time between the seal head of the sealing device 60 and the tag, the thread material or the water-permeable filterable sheet that is the object to be sealed becomes longer, so that optimum sealing conditions can be easily set. Appropriate sealing conditions can be set even when the material is changed.

As a method of manufacturing the extraction bag sheet 5 with the extraction bag sheet manufacturing machine 1 of the present embodiment, first, the tag tape original fabric 2r, the yarn material original fabric 3r, and the sheet original fabric 4r are respectively set in the present machine. Then, the tag supply device 20 feeds the tag tape 2t from the tag tape original fabric 2r, cuts it into the tag 2, and carries the tag 2 on the peripheral surface of the rotary carrier 10 at a predetermined interval.
