Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a long tape-like product for bundling a plurality of manufactured long tape-like products, such as slide fasteners, with a binding material. Concerning how to tie things together.

(Prior art) This type of method was already developed by the applicant in Japanese Patent Application Laid-Open No. 60-183.
No. 318 discloses a binding and finishing device for long products. The technique disclosed in that publication is to hold the tip of a long piece of binding material with a holding mechanism, feed the binding material by a predetermined amount with a feeding mechanism, place the long product on the fed-out binding material, and use a presser mechanism to While holding down the elongated product, the supply side portion of the binding material is inserted into the holding mechanism using the insertion mechanism, and the binding material is joined using the joining mechanism.

[Problem that the invention seeks to solve]

The binding material used for bundling with the above-mentioned device is a tape-like material mainly made of synthetic resin.In order to securely bind without loosening, we utilize the slipperiness and elasticity peculiar to synthetic resin. At the time of feeding, an amount approximately equivalent to the length required for bundling is sent, a long product is put into this, and the product is bundled in the above-mentioned process.

However, if you try to bundle them with paper binding material in the above process, there is a drawback that it will break because it does not expand or contract.

This invention was developed with the aim of making it possible to securely and firmly bundle items using a paper binding material.

[Means for solving problems]

The method for bundling long tape-like objects according to the present invention achieves the object of the present invention by initially feeding a smaller amount of bundling material than is necessary for bundling, and then feeding the insufficient amount under tension and bundling. It is something to be achieved.

To explain in more detail, the process of drawing out the binding material across the binding position and pinching the tip thereof, the process of sending out the binding material in an amount shorter than the amount required for binding to the binding position and letting it hang down, and the hanging binding process. The process of supplying a plurality of long tape-like objects into the unit, the length that is insufficient to be bound to the binding unit is fed out under tension by applying tension to the clamping unit, and the long tape is separated at the binding unit. The process involves the following steps: enclosing a shaped object, joining both ends of the enclosed object to each other, and joining the joined parts.

For pressing, a mechanism 4 is provided, and a coupling mechanism 5 is provided on both sides of the device.

The holding mechanism 2 has an upper claw 6 and a lower claw 7 disposed vertically,
Each is biased by a spring (not shown) in the direction of joining to each other. Further, on the side where the clamping mechanism 2 is provided, there is a cutter 8 that enters between the upper and lower claws 6 and 7, and a push-out plate 9 that projects toward the bundling position 1. It moves linearly back and forth at a speed of .11.

The supply mechanism 3 consists of one system, and one system has a drive roller 12 and a presser roller 13 arranged above and below, and both rollers 12
．． The material 31 for binding is sandwiched between the rollers 13 and sent toward the binding position 1, and the presser roller 13 has a brake constituted by a pressing plate 16 that presses against the outer peripheral surface of the roller 13 with the force of a spring 15. A mechanism 14 is attached. The other system is composed of a feeder 17 located closer to the binding position 1 than the rain rollers 12 and 13 and feeding the binding material 31 toward between the upper and lower claws 6 and 7,
The feeder 17 is fixed to the upper part of a holder 19 that reciprocates in a straight line with a cylinder 18, and has a strip-shaped plate body with an insert piece 20 protruding from both sides of the holder 19, which can be opened and expanded by pushing the upper and lower claws 6 and 7 up and down. It also has a groove 21 on its surface that accommodates and guides the binding material 31. A groove 22 into which the cutter 8 enters is provided at the front end of the feeder 17.

The pressing mechanism 4 is the binding part 11! ! A main plate 23 that presses down the long tape-like objects 30 stacked in a stack from above when tying them together, and presses the front and rear parts of the long tape-like objects 30 at the position where they are tied, and the front end of the long tape-like object 3o. It consists of a pair of sub-holding plates 24.24 that hold down the rear end and the rear end, and each of the main and sub-ridge plates 23.24 is provided so as to be able to swing up and down via a hinge 25.26.

In the coupling mechanism 5, a stapler 27 is provided below the lower claw 7 so as to be tiltable toward the binding position 1 by the drive of a cylinder 28, and a die 29 is mounted below the holder 19 that holds the feeder 17. 27.

The method according to the present invention is carried out by the above-mentioned apparatus, and as shown in FIG. 1A and B, the binding material 31
After the tip of the binding material 31 is held in the clamping mechanism 2, both rollers 12 and 13 of the supply mechanism 3 feed the binding material 31 to the binding position. The length Q between the stapler 27 of the joining mechanism 5 and the die 2
It is fed out by the length of the part hanging down from the opposite position of 9. This length Q is shorter than the length that surrounds and bundles the long tape-like object 30, that is, the length L between points a and e in Figure B.

After stacking the long tape-like material 30 in the binding part 32 of the binding material 31 that has been sent out and hung down, B
As shown in the figure, the feeder 17 and the die 29 are driven forward while the drive roller 12 remains stopped.

This is because braking pressure is applied to the presser roller 13 by the spring 15 during this forward drive.

Binding material 3 drawn out by feeder 17 and die 29
1 is pulled out the required amount while feeling nervous. After that, stapler
27 is driven to connect the binding portions 32.

Furthermore, the binding operation using the device shown in FIG.
To explain with reference to the figures, as shown in figure A, the tip of the binding material 31 is held between the upper and lower claws 6 and 7, and then the drive roller 1
2 is driven to hang the binding material 31 in a U-shape at the binding position 1 as shown by the two-dot chain line to form a binding part 32.

As shown in FIG. 3B, a long tape-like material 30 is attached to the knotted portion 32.
After being stacked and supplied, the stacked long tape-like materials 30 are pressed down by the main and sub-pressing plates 23 and 24.

As shown in FIG. 3C, with the drive roller 12 stopped, the feeder 17 and the die 29 are moved forward, and the front end of the feeder 17 is inserted between the upper and lower claws 6 and 7, and the bundle is surrounded by the die 29. The front and rear parts of the material 31 are brought into close contact. As the feeder 17 and die 29 move forward, only the presser roller 13, which is under braking pressure, rotates, and the required amount of binding material 31 is fed under tension.

As shown in the third diagram, the stapler 27 is tilted toward the die 29 to bind the staples 33, and then the cutter 8 is moved forward to cut the portion of the binding material 31 that is reversed at the front end of the feeder 17. do.

As shown in FIG. 3E, by first moving the extrusion plate 9 forward, the upper end of the binding portion 32 is pushed out from between the lower claw 7 and the feeder 17, and then the feeder 17 and die 29 are moved back. Then, the binding material 3 cut from the binding part 32
1 is held between the upper and lower claws 6, 7, and after each ridge plate 23, 24 is lifted and opened, the bound long tape-like material 30 is sent out of the binding position 1. Then the third
The operation is repeated as shown in Figure A. In the case of this device as well, as shown in FIG. 4, the drive roller 12 initially feeds the length Q, and later feeds out the shortfall to the length L required for bundling.

[Effects of the Invention] □ According to the method for bundling long tape-like objects according to the present invention, after the leading end of the bundling material is pinched, a length shorter than the length necessary for bundling is fed out, so that there is no shortage of material at the time of bundling. This method involves feeding out a length of paper under tension, encircling it, and joining it together.Although it is a paper binding material, strong tensile force is not applied to the binding part that is fed out first. The binding material does not break and can be tightly tightened under tension.
