In addition, the fifth processing unit 350 is a processing unit for inspecting the finishing state of the second zipper chain 102. In some cases, a sixth processing unit for screening good or defective products based on the inspection result of the fifth processing unit 350 is provided.

Without being limited thereto, as shown in FIG. 6, with respect to the second zipper chain 102 supplied to the lower side of the processing unit 320, the upper end portion of the second zipper chain 102 is utilized corresponding to the opening operation of the gripper pair 200. 102j forcibly pulls each zipper tape 111 in the opposite direction. Corresponding to the pulling of the respective zipper tapes in the opposite direction, the zipper tapes 111 of the second zipper chain 102 are displaced in such a manner as to be separated from the other zipper tape 111 as schematically shown by the broken line in FIG. As a result, a gap is formed between the respective curved side edge portions 111k of the pair of fastener tapes 111, and the engaging element 112m is exposed through the gap. Further, the pair of grippers included in the gripper pair 200 are configured to be able to approach and separate from each other.

In the present embodiment, the space forming portion included in the second processing unit 320 is configured such that a pair of fastener tapes 111 are pulled in opposite directions in response to the action of the holder pair 200, and the exposed portion is broken. The zipper chain 102 has a snap element 112m. In this case, it is possible to prevent the space forming device from being disposed on the upstream side of the zipper manufacturing apparatus 600, and it is possible to form the space portion 116 with respect to the nip element 112m while using the existing gripper pair 200.

As shown in FIG. 8, the second processing unit 320 includes a space forming portion 320k and a lifting portion 320j for moving the space forming portion 320k up and down. The elevation unit 320j is configured to be able to move up and down between the position where the space forming unit 320k interferes with the movement trajectory of the holder pair 200 in the circumferential direction and the position where no interference occurs. In the illustrated example, the space forming portion 320k can be vertically displaced in the vertical direction in response to the operation of the lifting portion 320j. The lifting portion 320j includes, for example, a cylinder. The position of the space forming portion 320k can be adjusted by the control of the expansion and contraction of the cylinder. In another example, another mechanism can be used.

In FIG. 9(a), the space forming portion 320k is located at a non-interference position that does not interfere with the movement locus of the gripper pair 200 in the circumferential direction. In FIG. 9(b), the space forming portion 320k is located at an interference position that interferes with the movement trajectory of the pair of grippers 200 in the circumferential direction. 9(a) and 9(b), the space forming unit 320k can be shifted from the non-interference position to the interference position based on the operation of the lifting unit 320j. 9(b) and 9(c) show that the space forming portion 320k is actuated at the interference position, and the space forming portion 320k is formed in the engaging element 112m of the upper end portion 102j of the second fastener chain 102.

The space forming portion 320k illustrated in the diagram of FIG. 8 includes a cutter 321 and a mold 323. More specifically, the space forming portion 320k includes a cutter 321, a cutter guide 322, a mold 323, a first link 324, a pivot link 325, a second link 326, and a cylinder 327. The first link 324 is rotatably coupled to the first end of the pivot link 325, and the second link 326 is rotatably coupled to the second end of the pivot link 325. The cylinder 327 is coupled to the second end of the pivoting link 325 via a second link 326. The cutter 321 is coupled to the first end of the pivoting link 325 via a first link 324. If the cylinder 327 is elongated, the cutter 321 advances in the groove of the mold 323. The bite element 112m of the upper end portion 102j of the second fastener chain 102 thus disposed in the mold 323 forms a space portion 116. The cutter 321 functions to break the occlusal element 112m at the center of the width of the narrow meshing element 112m. The cutter 321 has a long blade length in the vertical direction and a short blade width orthogonal to the vertical direction.

As shown in FIGS. 10 to 13, the cutter guide 322 is provided with a cutter 321 and has a slit 322s that guides the movement of the cutter 321 . The mold 323 has a groove portion 323g capable of guiding the engaging element 112m and/or capable of arranging the engaging element 112m, and a slit 323s capable of entering and advancing the cutter 321 . The slit 323s may be a bottomed groove or a bottomless groove. As the cylinder 327 is actuated, the cutter 321 advances toward the mold 323, and the cutter 321 advances in the slit 322s of the cutter guide 322, passes through the groove portion 323g of the mold 323, and continues along the slit 323s. When the nip element 112m is disposed in the slit 323s of the mold 323, the cutter 321 breaks the center of the width of the nip element 112m, and the occlusion function of each of the fastener elements 112 that engages the element 112m is broken. Thus, the space portion 116 is formed in the engaging element 112m of the second fastener chain 102.

In the example shown in Figs. 12 and 13, the engaging element 112m is interposed between the cutter guide 322 and the mold 323, thereby suppressing or reducing the movement of the engaging element 112m when the cutter 321 breaks the engaging element 112m. Bit.

The third processing unit 330 shown in FIG. 14 is configured such that the slider 115 can be disposed in the vicinity of the end portion of the remaining occlusal element 112m of the second fastener chain 102 via the space portion 116. In other words, the third processing unit 330 is configured and operated by the second processing unit 320 supplying the slider 115 to the second fastener chain 102 in which the space portion 116 is formed.

The third processing unit 330 illustrated in the diagram of FIG. 14 includes a slider penetration portion 330k and a lifting portion 330j for moving the slider penetration portion 330k up and down. In response to the operation of the lifting portion 330j, the slider penetration portion 330k can be vertically displaced in the vertical direction. The lifting portion 330j includes, for example, a cylinder. The position of the slider penetration portion 330k can be adjusted by the control of the elongation and contraction of the cylinder.

In Fig. 14, the slider penetration portion 330k is located at a non-interference position that does not interfere with the pair of grippers 200 displaced in the circumferential direction. On the other hand, in Fig. 15, the slider penetration portion 330k is lowered from the non-interference position to the interference position based on the operation of the elevation portion 320j. With the lowering of the slider penetration portion 330k, the slider 115 passes through the engaging element 112m of the upper end portion 102j of the second fastener chain 102. The gripper pair 200 is controlled in synchronization with the lowering of the slider penetration portion 330k in order to promote the retreat of the slider 115. Control to increase the spacing of the gripper pair 200 can be performed.

In some cases, the slider 115 is disposed in the vicinity of the end portion of the remaining occlusal element 112m, so that the occlusal element 112m is not engaged. In the other case, the slider 115 is disposed in the vicinity of the end portion of only the remaining engaging element 112m, and the engaging element 112m is not engaged without moving. In Fig. 16, the slider penetration portion 330k is moved from the closed state to the open state at the interference position, and the slider 115 is placed at the upper end portion 102j of the second fastener chain 102.

The slider through portion 330k of the example illustrated in FIGS. 14 to 16 has a first holder 331 to a third holder 333 for holding the slider 115, and the first holder 331 and the second holder 332 are coupled to each other. A pair of pivoting links 334 at the lower end portion are pivotally disposed with a base 335 of each of the pivoting links 334 and a pushing member 336 for opening and closing the pair of pivoting links 334.

The first holder 331 is configured to receive and/or hold the slider 115 by its lower blade side. The second holder 332 is configured to receive and/or hold the slider 115 with its flange and upper wall side. The third holder 333 is configured to be housed and/or held in the vicinity of the tab mounting post and/or the connecting post of the slider 115.

The third holder 333 is disposed to be displaceable between an open position shown by a broken line in FIG. 14 and a closed position shown by a solid line. For example, the third retainer 333 is coupled to the pivot link 334 via the cylinder, displaced between the closed position and the open position in response to actuation of the cylinder. In this case, the slider 115 is surely held by the first to third holders 331 to 333, and allows the slider 115 to further surely pass through the bite chain of the second fastener chain 102 held by the holder pair 200. Teeth 112m.

The pusher 336 has a tapered portion 336r that is tapered so as to be narrowed toward the lower side in the vertical direction. Each of the pivoting links 334 has a protruding portion 334r provided to be close to each other in the vertical direction. With this configuration, the interval between the first holder 331 and the second holder 332 can be gradually expanded by the lowering of the pusher 336.

The operation of the processing unit 330 will be further described. In addition, it is assumed that the slider 115 is held in advance by the first holder 331 to the third holder 333.

The second fastener chain 102 is disposed below the third processing unit 330 along with the circumferential displacement of the gripper pair 200. The elevating portion 330j of the third processing unit 330 displaces the slider penetration portion 330k from the non-interference position to the interference position in the vertical direction. In this process, the upper end portion 102j of the second fastener chain 102 is inserted into the gap between the first holder 331 and the second holder 332. With the further lowering of the slider penetration portion 330k, the upper end portion 102j of the second fastener chain 102 enters the slider 115. Finally, the slider 115 is disposed in the vicinity of the end portion of the bite element 112m, and the end portion of the bite element 112m is non-engaged by the slider 115.

Then, the slider penetration portion 330k is turned from the closed state to the open state. In detail, the pusher 336 is advanced downward in the vertical direction, and along with this, the pair of pivot links 334 are pivoted away from each other. The slider penetration portion 330k can place the slider 115 on the upper end portion 102j of the second fastener chain 102 as described above. Further, the driving source for displacing the pusher 336 up and down may be, for example, a cylinder or the like.

When the slider penetration portion 330k is in the closed state, the insertion path of the second fastener chain 102 is disposed between the first holder 331 and the second holder 332. This insertion is defined by the respective opposing faces of the first holder 331 and the second holder 332. An inclined surface 331p is provided on the opposing surface of the first holder 331. An inclined surface 332p is provided on the opposing surface of the second holder 332. Each of the inclined surface 331p and the inclined surface 332p is tapered, and the insertion opening of the insertion path can be made wider.

There are various forms and methods for supplying the slider 115 to the slider penetration portion 330k. In one example, after the slider 115 is supplied to the first holder 331, the slider 115 is sandwiched by the first holder 331 and the second holder 332, and finally the third holder 333 is disposed above the slider 115.
