The lower clamp 32 on the lower end side of the belt T that clamps the zipper SF, the laser processing parts 40 that cut the upper and lower parts of the belt T of the zipper SF, and the correction of the slider SL of the zipper SF relative to the conveying direction The inclined slider placement device 50. In addition, the posture in which the longitudinal direction of the slide fastener SF is vertical in this embodiment refers to a posture in which the width direction of the pair of tapes T of the slide fastener SF is along the conveying direction.

Here, the slide fastener SF is demonstrated. As shown in FIG. 17, the zipper SF includes a pair of tapes T, a plurality of elements E respectively provided on the opposing tape side edges of the pair of tapes T, and the plurality of elements E of the pair of tapes T are engaged or The separated slider SL, the upper stop part Pa provided in one end part of the element E of a pair of tape T, and the bottom stop part Pb provided in the other end part of the element E of a pair of tape T, respectively. In addition, when the slide fastener SF is supplied to the tape length adjustment device 10, the slider SL is located at a position slightly closer to the bottom stop Pb from the top stop Pa. In addition, the fastener element E may be any of metal fastener elements, synthetic resin fastener elements, and coil-shaped fastener elements. In addition, in the slide fastener SF, the side with the pull tab is the front side, and the side without the pull tab is the back side. In addition, the slider SL includes an upper plate D1 and a lower plate D2, which are arranged to be separated from each other in the left-right direction in FIG. 7, a guide post D3 that connects the upper plate D1 and the lower plate D2, and a pull tab for attaching the pull tab Install column D4.

As shown in FIGS. 2 and 7, the conveying device 20 includes a pair of guide rails 21 which are arranged to sandwich the surface and back of the zipper SF to guide the zipper SF; and a conveying member 22 that connects the pair of guide rails 21 The upper zipper SF is transported from the upstream side to the downstream side.

The pair of guide rails 21 are rod-shaped members with a rectangular cross section, and are arranged in parallel in the front-rear direction. And, as shown in FIG. 7, the interval T1 between the pair of guide rails 21 is set to be greater than or equal to the thickness T2 of the element E of the slide fastener SF and less than or equal to the thickness T3 of the slider SL of the slide fastener SF. Thereby, the slider SL of the slide fastener SF is hooked on the upper surface of the pair of guide rails 21, so the slide fastener SF can move in the front-to-rear direction without falling down. The thickness T3 of the slider SL is the distance between the upper end (the left end of FIG. 7) of the pull tab mounting column D4 of the slider SL and the lower surface of the lower plate D2 (the right side of FIG. 7). Furthermore, the interval T1 between the pair of guide rails 21 is more preferably set between the upper surface of the upper plate D1 (the left side of FIG. 7) of the slider SL and the lower surface of the lower plate D2 (the right side of FIG. 7) The distance is below T4. Thereby, both the upper plate D1 and the lower end of the lower plate D2 (the lower end of FIG. 7) of the slider SL are supported on the upper surface of the pair of guide rails 21, so that the inclination in the thickness direction of the slider SL can be prevented, and the The slider SL is in a stable posture.

As shown in FIGS. 1 and 7, the conveying member 22 includes: a drive rod 23 arranged in parallel with the guide rail 21; and a plurality of conveying arms 24 arranged on the upper surface of the drive rod 23 at equal intervals in the front-rear direction , Extending to the upper surface side of the guide rail 21.

The drive lever 23 is driven by a drive device not shown in the figure so as to draw a rectangular track (see arrow M in FIG. 1) in a horizontal plane orthogonal to the vertical direction. The transport arm 24 is a plate-shaped member having a rectangular cross-sectional shape, or a rod-shaped member having a cylindrical or cylindrical cross-sectional shape, and its tip reaches a position on the opposite side of the center of the pair of rails 21 in the left-right direction. Therefore, as shown in FIGS. 2 and 3, when the drive lever 23 moves to the front side, the conveyance arm 24 contacts the side surface of the tape T of the slide fastener SF, and conveys the slide fastener SF to a downstream side. Thereby, every time the conveyance member 22 drives once so that a rectangular-shaped track may be drawn, the some slide fastener SF is conveyed at equal intervals by a predetermined distance. That is, the plurality of slide fasteners SF are intermittently conveyed by the conveying member 22.

In addition, each stop position of the plurality of slide fasteners SF conveyed by the conveying member 22 may become various processing positions. In the present embodiment, as shown in FIG. 2, one stop position becomes the standby position WP, and the downstream stop position adjacent to the standby position WP becomes the processing position CP. In the standby position WP, the tape T of the zipper SF is pulled down by the lower jig 32 until the top stop Pa comes into contact with the slider SL (refer to FIGS. 4 and 8). At the cutting position CP, the laser processing part 40 is used to cut the tape T between the upper clamp 31 and the upper stop Pa, and between the lower clamp 32 on the tape T and the lower stop Pb. At (refer to Figure 5, Figure 11).

As shown in FIGS. 2, 7, and 9, the upper clamp 31 includes left and right clamp members 31 a that clamp the upper ends of the pair of belts T. As shown in FIGS. The left and right clamp members 31a are above the guide rail 21 and are arranged in parallel with the guide rail 21.

In addition, the upper clamp 31 clamps the upper ends of the pair of belts T, so that the posture of the upper portion of the pair of belts T above the upper stopper Pa can be fixed in the left-right direction. Thereby, the cutting position and cutting angle of the tape T by the laser processing part 40 can be fixed.

The lower clamp 32, as shown in Figures 2, 7 and 9, includes: left and right drive plates 33 below the guide rail 21 and arranged in parallel with the guide rail 21; the left and right first clamp members 34 are respectively mounted on the left and right The drive plate 33 clamps the lower ends of the pair of belts T of the zipper SF at the standby position WP; and the left and right second clamp members 35 are respectively mounted on the left and right drive plates 33 to clamp the zipper SF at the processing position CP A pair of lower ends with T. In addition, the drive plate 33 on the left is not shown.

The left and right drive plates 33 are driven by a drive device not shown in the left and right directions and in the up and down directions. Specifically, the left and right drive plates 33 are driven inward in the left and right direction to close the first jig member 34 and the second jig member 35 to clamp the belt T, and the left and right drive plates 33 are driven outward in the left and right direction. The first clamp member 34 and the second clamp member 35 are opened to release the tape T. In addition, since the first clamp member 34 and the second clamp member 35 clamp the tape T, the left and right drive plates 33 are driven downward, so that the tape T of the zipper SF at the standby position WP and the processing position CP is simultaneously It is pulled down (refer to Figure 8, Figure 10).

Then, the tape T is pulled down by the first clamp member 34 (lower clamp 32), and in the standby position WP, the tape T is pulled down until the top stop Pa is in contact with the slider SL (see FIG. 8). In addition, the tape T is pulled down by the second clamp member 35 (lower clamp 32), and the tape T has a fixed tension at the processing position CP (see FIG. 10). Then, by making the belt T have a fixed tension, the posture of the portion of the pair of belts T lower than the slider SL can be fixed in the left-right direction. Thereby, the cutting position and cutting angle of the tape T by the laser processing part 40 can be fixed. In addition, the clamping force of the first clamp member 34 and the second clamp member 35 of the lower clamp 32 is set to be lower than the force for pulling the belt T down. Therefore, after the top stop Pa comes into contact with the slider SL, the first clamp member 34 and the second clamp member 35 move downward in a sliding manner relative to the belt T, so that excessive force is not applied to the belt T. Therefore, the unevenness of the length of the belt T caused by the extension of the belt T can be suppressed.

In the slider mounting device 50 configured as described above, as shown in FIG. 10, the left and right connecting members 51 are closed, and a part of the slider SL is inserted into the recesses 51 a of the left and right connecting members 51. At this time, the slider SL is in a state of being sandwiched between the slider placement device 50 and the guide rail 21 in the vertical direction. Thereby, the inclination of the slider SL with respect to the conveying direction can be corrected, and therefore the slider SL, the top stop portion Pa, and the belt T can be positioned at predetermined positions. Therefore, the cutting position and cutting angle of the tape T by the laser processing unit 40 can be fixed.

The sorting unit 12, as shown in Figs. 1, 12 and 13, includes: a conveyor 60 that receives the zipper SF at the downstream end of the guide rail 21 of the conveyor 20 and conveys it to the downstream side (the left side of Fig. 12); The first sensor 71 to the third sensor 73 stop the conveyor 60 at the first discharge position P1 to the third discharge position P3; and the discharge device 80 discharges the zipper SF carried by the conveyor 60 to the storage box 90.

As shown in FIG. 1, the left and right holding rods 62 are arranged in a position to receive the slide fastener SF so as to be continuous on a straight line with respect to the pair of guide rails 21. Therefore, the transport member 22 can transport the slide fastener SF to the left and right holding rods 62, and the transported slide fastener SF is held by the left and right holding rods 62. In addition, the holding rod 62 on the left side is configured to be expandable and contractible, and the held slide fastener SF is released by contracting the holding rod 62 on the left side on the guide plate 81 described later.

The first sensor 71 detects the conveyor 60 that has moved to the first discharge position P1, and stops the conveyor 60 at the first discharge position P1. The second sensor 72 detects the conveyor 60 that has moved to the second discharge position P2, and stops the conveyor 60 at the second discharge position P2. The third sensor 73 detects the conveyor 60 that has moved to the third discharge position P3, and stops the conveyor 60 at the third discharge position P3. Therefore, the conveyor 60 can be stopped at any one of the first discharge position P1 to the third discharge position P3, and the slide fastener SF can be discharged (see FIG. 14). Therefore, for example, ten slide fasteners SF can be respectively discharged to the 1st discharge position P1-the 3rd discharge position P3. In addition, the sensors 71 to 73 can move in the left-right direction and can be arranged corresponding to the length of the slide fastener SF.

The horizontal position of the receiving plate 84 is a position for receiving the zipper SF (refer to FIG. 15), and the falling position of the receiving plate 84 is a position where the receiving plate 84 is inclined downward to move the zipper SF to the storage box 90 (refer to FIG. 16) . Then, the receiving plate 84 is rotated to move the slide fastener SF, and therefore the slide fastener SF is stored in the storage box 90 with its front side facing upward. In addition, the receiving plate 84 includes a convex portion 84b that stops the slide fastener SF that has fallen on the slide groove plate 83.

The storage box 90 is installed so as to be movable in the front-rear direction by a driving device not shown. With this, for example, a bundle of zippers SF can be stored as the first row in the first ejection position P1 to the third ejection position P3, and then the storage box 90 is moved forward by a predetermined distance to move the zipper SF to the first ejection position P1 to the third ejection position. A bundle of zippers SF is respectively accommodated in the discharge position P3 as the second row. That is, in this embodiment, multiple rows of three zipper SF rows can be produced in the storage box 90.
