Hereinafter, operations of the manufacturing apparatus 100 for a slide fastener will be described mainly with reference to FIGS. 7 to 20. FIG. 7 schematically illustrates that the slider supply unit 110 supplies at least one slider 20 to the conveyance path T1 of the fastener chain 10, and the fastener chain 10 is clamped by the clamper 120 and pulled to the downstream side. FIG. 8 schematically illustrates that the slider 20 is passed through the fastener elements 14 of the fastener chain 10 by carrying the fastener chain 10 toward the downstream side by the holder 120. FIG. 9 schematically illustrates that at least one slider 20 supplied to the conveyance path T1 of the fastener chain 10 by the slider supply unit 110 passes through the teeth 14 of the fastener chain 10. FIG. 10 schematically shows that the slider 20 that has passed through the fastener elements 14 of the fastener chain 10 is released from the slider supply unit 110 and is conveyed to the downstream side together with the fastener chain 10.

As can be seen from FIG. 7, the holder 120 on one side moves along the movement trajectory L1, and the holder 120 on the other side moves along the movement trajectory L2. The sprocket 14 on one side moves along the movement locus L1 ', and the sprocket 14 on the other side moves along the movement locus L2'. The slider 20 held by the slider holder 110 is supplied to the movement trajectory L1 ′ and the movement trajectory L2 ′ of the sprocket 14. Therefore, the sprocket 14 in an engaged state according to the downstream movement of the holder 120 enters the rear mouth of the slider 20. Then, the engagement of the sprocket 14 in the slider 20 is released, and each sprocket 14 comes out of the slider through the two front openings of the slider 20, respectively.

As can be seen from FIG. 10, in some cases including the illustrated examples, the holding of the slider 20 by the slider holder 110 is released during the process of pulling the zipper fastener chain 10 to the downstream side by the clamp 120, and the slider 20 is Carry it downstream. Thereby, it can be further known from the description described later that the slide fastener chain 10 can be smoothly pulled back upstream by the roller pair 300 and transported.

FIG. 12 schematically shows that the fastener chain 10 is pulled back to the upstream side by the roller pair 300. FIG. 14 schematically shows that the fastener chain 10 is sandwiched by the roller pair 300. FIG. 15 schematically shows that the fastener chain 10 is pulled back to the upstream side by the roller pair 300. FIG. 16 schematically shows that the fastener chain 10 is conveyed downstream by the roller pair 300. The fastener chain 10 is sent to a chute (not shown), for example.

After the slider 20 has passed through the fastener elements 14 of the fastener chain 10, the first fasteners 30 are mounted on each fastener chain belt 11 of the fastener chain 10. When or after the first fastening member 30 is mounted by the first fastening member mounting portion 210, the clamping of the zipper fastener chain 11 by the holder 120 is released. The non-limiting example of the attachment form of the first fastening member 30 is as described above.

In some cases including the illustrated examples, after the slider 20 has passed through the sprocket 14 of the fastener chain 10, the holding of the slider 20 by the slider holder 110 is released during the downstream movement of the holder 120. . As a substitute for the slider holder 110, the first roller 310 is disposed directly below the conveyance path T1 of the fastener chain 10. After the first fastener 30 is attached to the fastener chain 10, the fastener chain 10 is pulled back to the upstream side by the roller pair 300. In some cases, the roller pair 300 can work so that the fastener chain 10 released from the clamping of the clamper 120 may be pulled back to the upstream side. Thereby, the first fastener 30 attached to the fastener chain 10 is detached from the first fastener attaching portion 210, for example, from the first mold 212 thereof. After the first fastener 30 is removed from the first mold 212, the fastener chain 10 hangs downward in the vertical direction by the weight of the attached slider 20 and / or the first fastener 30. By shifting the pressing roller 320 in the downstream direction, the fastener chain 10 can be conveyed downward in the vertical direction.

The cutting tool 400 cuts the fastener elements 14 of the fastener chain 10 when the fastener chain 10 is cut. FIG. 19 schematically illustrates that one or more second fasteners 40 are attached to the fastener chain 10 by the second fastener attachment portion 220.

In some cases including the illustrated examples, the fastener chain 10 is pulled back toward the upstream side (the side of the second fastening member mounting portion), and then the fastener chain 10 is transferred toward the downstream side. When the fastener chain 10 is pulled back by the roller pair 300 to the upstream side, the downstream end of the fastener chain 10 tribe descends to the fastener chain 10 extending between the second fastener installation portion 220 and the first fastener installation portion 210. Below the transport path T1. Therefore, the roller pair 300 can allow the fastener chain 10 to be conveyed at an arbitrary predetermined distance without any restriction. As a result, the slide fastener 5 having a desired length can be manufactured without depending on the physical distance between the first fastener attaching portion 210 and the second fastener attaching portion 220.

After the roller pair 300 conveys the fastener chain 10 to the downstream side with an arbitrary predetermined length, the rotation of the first roller 310 is stopped. Then, the second fastener 40 is attached to the fastener chain 10 by the second fastener attaching portion 220. At the same time or thereafter, the fastener chain 10 is cut by the cutter 400. In this way, the slide fastener 5 shown in FIG. 1 is manufactured. The clamper 120 is returned to the initial position, and a slider holder 110 (that holds a slider) is provided directly below the conveyance path T1 of the fastener chain 10, thereby manufacturing the next fastener 5.

As can be understood from the description, a method for manufacturing a slide fastener including the following steps is also disclosed in this specification. Step: Supply at least one slider 20 to the conveying path T1 of the fastener chain 10; Step: Hold the fastener chain 10 and pull it to the downstream side, in the process, the slider 20 passes through the fastener chain Steps 14 of the chain 10; Step: After the slider 20 passes through the teeth 14 of the fastener chain 10, install more than one of the downstream side ends of each fastener chain belt of the fastener chain 10 Step: using at least one roller pair 300, pull back the zipper fastener chain 10 on which the first fastener 30 is mounted to the upstream side, and then, pull the zipper fastener chain 10 Transfer to the downstream side; Step: Install one or more second fasteners 40 on the fastener chain 10 on which the first fastener 30 is mounted on the downstream side end of each fastener chain belt.

Each feature described in the manufacturing apparatus 100 for a slide fastener is understood to be common also in the manufacturing method of a slide fastener, and the repeated description is abbreviate | omitted.

FIG. 21 is a schematic view showing a configuration and / or operation of another manufacturing apparatus for a slide fastener, and schematically illustrates a fastener chain sandwiched between a pair of rollers whose upper rollers are disposed on a downstream side with respect to a lower roller. As can be seen from the non-limiting example of FIG. 21, in some cases, the upper roller of the roller pair 300 is disposed on the downstream side than the lower roller. The first roller 310 is a lower roller, and the second roller 320 is an upper roller. The roller pair 300 pulls the fastener chain 10 back to the upstream side, and then transfers the fastener chain 10 to the downstream side. When the fastener chain 10 is pulled back to the upstream side, the second roller 320 orients the fastener chain 10 toward its discharge direction. When the fastener chain 10 is conveyed downstream, the fastener chain 10 is sent obliquely downward from the roller pair 300. This facilitates smoother discharge of the fastener chain 10 from the roller pair 300. In some cases, the angle θ3 formed by the axis D2 connecting the rotation center of the first roller 310 and the rotation center of the second roller 320 with respect to the vertical direction D1 is an acute angle, and in some cases, it is 45 ° or less.

Based on the teachings described above, various modifications can be added to the embodiments as long as they have ordinary knowledge in this field. The symbols added in the scope of patent application are for reference, and should not be used as a reference for limiting the purpose of interpreting the scope of patent application.
