Description

Space forming apparatus, space forming method, and slide fastener manufacturing method

The present invention relates to a space forming apparatus, a space forming method, and a slide fastener manufacturing method.

To cut out a plurality of slide fasteners from a long continuous fastener stringer, or to arrange fastener parts such as an upper stopper, a lower stopper, and a slider at a desired position of a long fastener stringer A space forming apparatus is known in which a part of an element fixed on a fastener tape is removed to form a space on which a fastener element does not exist on a fastener stringer.

For example, Japanese Patent Laid-Open No. 59-137140 (Patent Document 1) discloses an apparatus for automatically forming a space and cutting a fastener chain. A part of the element is cut by the element cutter arranged in the element cutting mechanism, and a space is formed on the fastener chain. Thereafter, the fastener chain with the fly (fabric) is manufactured by cutting the fastener chain at a predetermined position in the space by a chain cutter disposed in the chain cutting mechanism.

Japanese Patent Laid-Open No. 8-322612 (Patent Document 2) discloses a space device for more effectively removing the fastener element without damaging the core. Here, in a state where the meshing head existing in the space forming section of the fastener element row is sandwiched between the punch and the die, a part of the leg portion of the fastener element row is cut and scattered by the cutting blade. After the cutting, the remaining portions of the meshing head and the leg remaining on the fastener tape are pushed out and removed while being sandwiched between the punch and the die, thereby forming a space where no element is present on the fastener.

In the above space forming apparatus, a positioning mechanism is provided for restricting the positional deviation of the space portion. For example, in the spacer device disclosed in Patent Document 1, a positioning rod urged downward by a compression coil spring is provided in a blind hole provided in a lower portion of a lifting ram. Positioning is performed by the positioning rod descending with the lowering of the ram and fitting between the elements. In the spacer device of Patent Document 2, two positioning pins are arranged before and after the cutting blade, and the positioning of the space portion is performed by controlling the two positioning pins to engage with the element.

However, the positioning rod described in Patent Document 1 moves up and down in cooperation with the element cutter while being always urged by a spring. Therefore, after the ram is lowered and the element is cut by the element cutter, the positioning rod remains in the state of applying an elastic force to the element even when the ram is raised. In addition, misalignment of the fastener stringer may occur. Furthermore, in the spacer device described in Patent Document 1, the cutting residue of the fastener element may not be sufficiently removed and may remain on the tape, which may cause a problem when the fastener material is manufactured in the subsequent steps. is there.

For example, as shown in FIG. 5, the apparatus described in Patent Document 2 can more reliably remove the cut residue of the element by pushing the cut element downward with a punch. However, the spacer device described in Patent Document 2 controls the two positioning pins placed before and after the cutter, and the chain tension rod or the chain holding rod provided at a location different from the positioning pins, respectively. Therefore, the number of parts of the apparatus increases, and the positioning operation and the control mechanism are complicated.

The following embodiments exemplify apparatuses and methods for embodying the technical idea of the present invention. The technical idea of the present invention is the following in terms of the structure, arrangement, material, etc. of the components. It is not something specific.

-Slide fastener 10-
Before explaining the space forming apparatus 100 according to the embodiment of the present invention, an example of the slide fastener 10 that can be manufactured by the space forming apparatus 100 is shown in FIG. The slide fastener 10 includes a pair of fastener stringers 14 in which a plurality of fastener elements 13 (hereinafter referred to as “elements”) are arranged in a row at opposing tape side edges 12 of the fastener tape 11, and one end of the element 13. An upper stopper 15, a lower stopper 16 disposed across the fastener tape 11 at the other end of the element 13, and a slider 17 slidably disposed along the row of the elements 13. Is provided. Each element 13 is formed of a metal or a resin, and includes a meshing head 131, a body 132 extending from the meshing head 131 to the fastener tape 11 side, and further from the body 132 to the fastener tape 11 side. A leg 133 is provided that extends and is fixed to the tape side edge 12.

When manufacturing the slide fastener 10 shown in FIG. 1, a long fastener stringer 14 as shown in FIG. 2 is prepared. The elongated fastener stringer 14 is prepared in a state where a plurality of facing elements 13 are engaged with each other on the fastener tape 11. As shown in FIG. 3, a part of the element 13 is removed from the fastener stringer 14 by a space forming apparatus 100 described later with reference to FIG. 4, and a space S where the element 13 does not exist is formed. The fastener stringer 14 is cut on the space S and / or the fastening parts such as the upper stopper 15 and the lower stopper 16 are arranged on the space S, and the slider 17 is mounted, as shown in FIG. The slide fastener 10 can be manufactured.

That is, the fastener stringer 14 is cut on the space S, and the slide fastener 10 to which the slider 17 is attached is manufactured. Alternatively, the upper stopper 15 and the lower stopper 16 are attached and arranged on the space S without cutting the fastener stringer 14, and then the fastener stringer 14 is cut to manufacture the slide fastener 10.

When the upper stopper 15 and the lower stopper 16 are not disposed, the slider 17 is prevented from being detached by sewing on clothes, a bag or the like to which the slide fastener 10 is attached in order to prevent the slider 17 from falling off the fastener element row. It can be carried out. Either the upper stopper 15 or the lower stopper 16 may be arranged.

-Space forming apparatus 100-
A schematic view of a space forming apparatus 100 according to an embodiment of the present invention is shown in FIG. The space forming device 100 is provided with a base 1 on which the fastener stringer 14 to be transported is placed, a cutter unit 2 that is provided on the base 1 so as to be liftable and cuts a part of the element 13, and positioning of the fastener stringer 14. The positioning mechanism 3 for performing the above operation, the urging mechanism 4 connected to the positioning mechanism 3 and the remaining portion of the element 13 cut by the cutter portion 2 are held and held, and the remaining portion is pushed downward of the base 1 to fasten the fastener stringer 14. A punch 6 and a die 7 (see FIG. 5 for the die 7) for removing the remainder of the element 13 from above are provided.

As shown in FIG. 4, a pair of guide rollers 8 for transporting the fastener stringer 14 on the base 1 on the front side and the rear side of the fastener stringer 14 in the transport direction (arrow A direction) across the base 1. 9 is provided. In the following description, the direction in which the fastener stringer 14 proceeds in the transport direction A is represented as “front (or forward in the transport direction)”, and the direction in which the fastener stringer 14 travels in the opposite direction is “backward (or rearward in the transport direction)”. It expresses.

The cutter part 2 is provided with a pair of cutting edges 21 facing each other at the tip, as shown in FIG. As shown in FIG. 4, the cutting edge 21 extends parallel to the longitudinal direction of the fastener stringer 14. The cutter unit 2 descends on the base 1 and cuts the element 13 of the fastener stringer 14. The cutter unit 2 is provided at an upper portion thereof, is driven by a press ram (not shown) connected to the cutter unit 2, and can move up and down on the base 1.

A groove 22 that is inclined with respect to the upper surface of the base 1 is formed inside the cutter unit 2. The rod-shaped positioning mechanism 3 is accommodated in the groove 22 and moves up and down on the base 1 in conjunction with the lifting and lowering of the cutter unit 2. The positioning mechanism 3 is movable along the groove 22. The positioning mechanism 3 is disposed obliquely with respect to the upper surface of the base 1 so that the upper part is positioned on the front side in the transport direction A and the lower part is on the rear side in the transport direction A. The positioning mechanism 3 has a claw portion 31 having a thin tip at one end. As can be seen from FIGS. 4 and 5, the claw portion 31 protrudes below the cutting edge 21 of the cutter portion 2.

As shown in FIG. 4, an urging mechanism 4 for urging the positioning mechanism 3 is connected to the end of the positioning mechanism 3 opposite to the claw portion 31. The urging mechanism 4 urges the positioning mechanism 3 diagonally downward from the front to the rear in the transport direction along the groove 22. By this downward biasing, one positioning mechanism 3 causes the claw portion 31 to be fitted between the adjacent elements 13. Furthermore, when the cutter part 2 moves downward, the positioning mechanism 3 moves obliquely upward relative to the cutter part 2 along the groove 22. By this obliquely upward movement, the claw portion 31 fitted between the elements engages with the element 13 on the front side in the transport direction, and pulls the fastener stringer 14 toward the transport direction A side (forward in the transport direction). ) Positioning can be performed. That is, the fastener stringer 14 is pulled in a direction approaching the cutter unit 2 from a position before being pulled by the positioning mechanism 3. Thereby, the element 13 to be cut can be positioned below the cutting edge 21 of the cutter unit 2. The conveyance direction A side means going forward in the conveyance direction, and the position in the conveyance direction A from the reference is defined as the conveyance direction A side with respect to the position of the element 13 and the claw portion 31 before conveyance. Details of the positioning operation will be described later.

The urging mechanism 4 is not particularly limited as long as it is a device that can switch between urging / biasing release to the positioning mechanism 3. In the present embodiment, for example, an air cylinder is preferably used. As the biasing mechanism 4, a device capable of switching between biasing / biasing release to the positioning mechanism 3, such as an air cylinder, is employed, so that the biasing mechanism 4 is biased to the positioning mechanism 3 according to the lifting / lowering operation of the cutter unit 2. Force and deenergization can be controlled. Therefore, as compared with the case where the positioning mechanism 3 is always urged by a spring as in the prior art, unnecessary force is not applied to the fastener stringer 14, so that the displacement of the fastener stringer 14 is suppressed.

The urging mechanism 4 is connected to an urging control mechanism 5 for controlling the urging mechanism 4. The urging control mechanism 5 controls the urging mechanism 4 based on the operations of the cutter unit 2 and the positioning mechanism 3. For example, when the cutter unit 2 descends on the base 1, the urging control mechanism 5 puts the urging mechanism 4 into the urging state. When the cutter unit 2 moves up on the base 1, the urging control mechanism 5 brings the urging mechanism 4 into the urging release state.

For example, when an air cylinder is employed as the urging mechanism 4, when the cutter unit 2 descends on the base 1, the urging control mechanism 5 supplies air to the air cylinder to move the positioning mechanism. A signal for energizing is output. When the cutter unit 2 moves up on the base 1, the urging control mechanism 5 outputs a signal for stopping the supply of air to the air cylinder and releasing the urging to the positioning mechanism 3. There is no restriction | limiting in particular in the specific aspect of the urging | biasing control mechanism 5. FIG. For example, the urging control mechanism 5 may be incorporated in an arithmetic control circuit (not shown) for controlling the operation of each mechanism of the space forming device 100 such as the cutter unit 2, the punch 6, and the die 7. .

As shown in FIG. 5, a punch 6 is arranged in a central region sandwiched between a pair of cutter parts 2. A die 7 is disposed in a space formed at the center of the base 1 so as to face the punch 6. The punch 6 and the die 7 can be moved up and down on the base 1. With the punch 6 and the die 7 sandwiching and holding the remaining portion of the element 13, the remaining portion of the element 13 can be reliably removed from the fastener stringer 14 by moving the remaining portion below the base 1. The space S can be more reliably formed on the stringer 14.

-Space formation method-
The space forming method according to the embodiment of the present invention will be described with reference to FIGS. 4 and 7 to 13. First, the fastener stringer 14 shown in FIG. 2 is conveyed onto the base 1 by the

guide rollers

8 and 9 shown in FIG. When the fastener stringer 14 is disposed at an appropriate position on the base 1 by a position detector (not shown), a press ram (not shown) connected to the cutter unit 2 is lowered, and the cutter unit 2 connected to the press ram. The positioning mechanism 3 is lowered onto the fastener stringer 14. As shown in FIG. 7, the claw portion 31 at the tip of the positioning mechanism 3 is positioned below the cutting edge of the cutter portion 2, so that the claw portion 31 contacts the element 13 before the cutter portion 2. .

After the claw portion 31 comes into contact with the element 13, the claw portion 31 is fitted between the

adjacent elements

13a and 13b as shown in FIG. When the cutter portion 2 further descends, the claw portion 31 located at the position indicated by the dotted line portion in FIG. 9 in the positional relationship with the cutter portion 2 indicated by the dotted line in FIG. 9 is moved between the element 13a and the element 13b by the biasing mechanism 4. While the element 13a and the element 13b are pulled in the conveying direction A side while being biased to be inserted therebetween, the rod-shaped portion of the positioning mechanism 3 is obliquely upward along the groove 22 (in the direction of arrow B in FIG. 9). ). Thereby, the claw part 31 of the positioning mechanism 3 performs positioning that draws (fastens) the fastener stringer 14 toward the conveyance direction A side. As a result, as shown by the solid line in FIG. 9, when the cutting edge 21 of the cutter unit 2 comes into contact with the element 13 c, the cutter unit 2 is adjusted to an appropriate position on the fastener stringer 14.

According to the space forming apparatus 100 according to the embodiment of the present invention, the positioning mechanism 3 moves in the limited space of the groove 22 so that the fastener stringer 14 is positioned at an appropriate position. Thereby, it is possible to prevent the non-cutting target element 13a adjacent to the cutting target element 13c from being cut and lost by the cutter unit 2 due to the displacement.

After the cutting edge 21 of the cutter unit 2 comes into contact with the element 13, as shown in FIG. 10, a predetermined pressure is applied downward from the cutting edge 21, whereby a part 134 of the element 13 (corresponding to the leg part 133 in FIG. 1). ) Is cut and scattered. After the cutting, the urging control mechanism 5 releases the urging state to the positioning mechanism 3 by the urging mechanism 4. Next, as shown in FIGS. 11 and 12, the cutter unit 2 and the positioning mechanism 3 are raised again above the base 1. When the positioning mechanism 3 remains biased as in the prior art, the claw portion 31 of the positioning mechanism 3 moves the

elements

13a and 13b backward in the conveying direction of the fastener stringer 14 due to the rising of the cutter portion 2. And move it. However, the positioning mechanism 3 according to the embodiment of the present invention is in a state in which the downward urging by the urging mechanism 4 is released, and therefore, as shown in FIG. Then, it moves upward as it is from the final positioning position (dotted line portion).

As shown in FIG. 13, the punch 6 is lowered onto the element 13 from between the pair of cutting edges 21 of the cutter part 2, and the remaining part of the element 13 (the meshing head 131 and the body part in FIG. 1) by the punch 6 and the die 7. (Equivalent to No. 132) is pushed out below the base 1. Thereby, the element 13 is reliably removed from the fastener stringer 14, and the fastener stringer 14 having the space S shown in FIG. 3 is manufactured.

According to the space forming apparatus 100 and the space forming method using the same according to the embodiment of the present invention, when the positioning mechanism 3 is raised by the biasing mechanism 4 and the biasing control mechanism 5 that controls the biasing mechanism 4. At the same time, the urging of the urging mechanism 4 to the positioning mechanism 3 is released. Thereby, since the downward urging | biasing of the positioning mechanism 3 is cancelled | released, when the positioning mechanism 3 engage | inserted between the elements 13 raises with the cutter part 2, the element 13 is not pulled back to a conveyance direction. As a result, the displacement of the fastener stringer 14 can be suppressed. By suppressing the displacement to the fastener stringer 14, the remaining portion of the element 13 is appropriately removed by the punch and die 7 when the remaining portion of the cut element 13 is removed from the fastener stringer 14 by the punch 6 and the die 7 thereafter. Can be held between. As a result, it is possible to provide the space forming apparatus 100 that can reliably remove the broken element 13. Furthermore, the space forming apparatus 100 according to the embodiment of the present invention can perform the positioning (positioning) of the fastener stringer 14 to an appropriate position with the single positioning mechanism 3, and thus the positioning component. The number of points can be reduced, and a space forming device having a simpler configuration can be provided.

(Other embodiments)
Although the embodiments of the present invention have been described as described above, it should not be understood that the descriptions and drawings constituting a part of this disclosure limit the present invention. It goes without saying that the present invention includes various modes that are not explicitly described herein, and can be embodied in the implementation stage without departing from the spirit of the invention.

For example, in the above description, an example in which an air cylinder is employed as the urging mechanism 4 has been described. However, the present invention is not limited to the air cylinder. For example, as shown in FIG. 14, an urging mechanism 40 using an elastic body 41 such as a spring can be used.

The urging mechanism 40 can switch between urging downward and urging release along the groove 22 of the positioning mechanism 3 by stopping the movement of the elastic body 41 and the elastic body 41 that urges the positioning mechanism 3. A switching mechanism 42 such as a simple air cylinder and a switching rod 43 are included. The elastic body 41 is connected to one end of the positioning mechanism 3. As shown in FIG. 15, the positioning mechanism 3 is provided with a recess 33 that can be engaged with the tip of the switching rod 43. The switching rod 43 advances and retreats in a direction in contact with or away from the positioning mechanism 3 and engages with the recess 33 to stop the movement of the elastic body 41. *

Also in this case, similarly to the above-described embodiment, after the claw portion 31 of the positioning mechanism 3 comes into contact with the element 13, the claw portion 31 is further lowered by the further lowering of the cutter portion 2, and the

adjacent elements

13a and 13b Fit between. When the cutter unit 2 is further lowered, the positioning mechanism is pulled while pulling the element 13a and the element 13b toward the conveying direction A side in a state where the elastic body 41 is biased to fit between the element 13a and the element 13b. The three rod-shaped portions slide obliquely upward along the groove 22 provided in the cutter portion 2. Thereby, the claw part 31 of the positioning mechanism 3 performs positioning that draws (fastens) the fastener stringer 14 toward the conveyance direction A side. Then, after the cutting edge 21 of the cutter part 2 comes into contact with the element 13 and a part 134 (corresponding to the leg part 133 in FIG. 1) of the element 13 is cut and scattered, the switching mechanism 42 is operated to switch the switching rod 43. Is engaged with the recess 33 of the positioning mechanism 3 (see FIG. 15). Thereby, the urging | biasing state to the positioning mechanism 3 by the elastic body 41 is cancelled | released.

Next, the cutter unit 2 and the positioning mechanism 3 are again raised above the base 1. At this time, the positioning mechanism 3 is in a state in which the downward urging by the elastic body 41 is released by the switching mechanism 42, so that it moves directly from the final positioning position (dotted line portion) in conjunction with the ascent of the cutter unit 2. Ascend upward.
