Next, the operation of the slide fastener assembling apparatus 10 will be described with reference to FIGS.

First, the downstream end of the continuous fastener chain C1 is gripped by the first gripper 20, and the continuous fastener chain C1 is transferred by a predetermined length from the rear side to the front side of the slide fastener assembling apparatus 10 by the first gripper 20 (first 1 transfer step, see FIG. 6). At this time, the cutting position of the continuous fastener chain C1 is positioned.

Next, the continuous fastener chain C1 is clamped by closing the upper and lower clamping plates 42 of the lower transfer device 40 (see FIG. 7). At this time, the continuous fastener chain C1 is clamped by the clamping plate 42, and the grip of the continuous fastener chain C1 of the first gripper 20 is released.

Next, the continuous fastener chain C1 is cut into a fastener chain C2 having a predetermined length by the cutting device 30 (see the cutting step, FIG. 8).

Next, the fastener chain C2 cut out from the continuous fastener chain C1 is transferred to the third transfer line L3 below the first transfer line L1 by the sandwiching plate 42 of the lower transfer device 40 (second transfer step, see FIG. 9). ).

Next, the downstream end of the fastener chain C2 is gripped by the second gripper 50 (see FIGS. 10 and 11). Then, the upper and lower clamping plates 42 of the lower transfer device 40 rotate and open when the second gripper 50 transfers the fastener chain C2 in the third transfer line L3, and the next continuous fastener in the first transfer line L1. The chain C1 is raised back to the position where it is clamped.

Next, the second gripper 50 moves the fastener chain C2 along the third transfer line L3 from the front side to the rear side of the slide fastener assembling apparatus 10 (see the first half of the third transfer step, see FIG. 12). The fastener chain C2 passes through the slider S held by the slider holder 61 of the attachment device 60, and the slider S is attached to the fastener chain C2 (see the slider attachment step, see FIG. 13). Note that the transfer by the second gripper 50 does not stop even when the slider S is attached. Further, after the slider S is attached to the fastener chain C2, the slider holder 61 releases the holding of the slider S. Accordingly, the slider S is transferred together with the fastener chain C2.

Next, the fastener chain C2 is further transferred to the rear side of the slide fastener assembling apparatus 10 by the second gripper 50, and the downstream end of the fastener chain C2 is the upper mold 71a of the injection machine 71 of the top stopper attaching apparatus 70 and the pressing portion. The portion 72 is transferred to a predetermined position between the lower molds 72a (see the second half of the third transfer step, see FIG. 14).

Next, the upper stopper P1 is injection-molded on the fastener chain C2 by the upper stopper attaching device 70, and the fastener chain C2 is finished into a slide fastener SF (see the upper stopper attaching process, see FIG. 15).

Further, the slide fastener SF is gripped by the third gripper 80 during the injection molding by the top stopper attaching device 70 (see FIGS. 16 to 18).

Next, the finished slide fastener SF is transferred by the third gripper 80 to the fifth transfer line L5 on the right side in the width direction separated from the third transfer line L3 (see the fourth transfer step, see FIG. 19). When the fourth gripper 90 is disposed on the left side in the width direction of the top stopper attaching device 70, the third gripper 80 may transfer the finished slide fastener SF to the left side in the width direction.

Next, the slide fastener SF is gripped by the fourth gripper 90, the grip of the slide fastener SF of the third gripper 80 is released, and the slide fastener SF is transferred from the third gripper 80 to the fourth gripper 90 (FIG. 20, see FIG.

Next, the slide fastener SF moves along the fifth transfer line L5 by the fourth gripper 90 and is transferred to the discharge portion (discharge step, see FIG. 22).

Thus, in the slide fastener assembling apparatus 10 of the present embodiment, the first gripper 20 and the second gripper 50 are used to perform the first transfer process and the cutting process, the third transfer process, the slider mounting process, and the top stopper mounting process. And in parallel.

As described above, according to the slide fastener assembling apparatus 10 of this embodiment, the continuous fastener chain C1 is transferred by the first gripper 20 and the first gripper 20 that transfer the continuous fastener chain C1 from the rear side to the front side. The cutting device 30 for cutting the continuous fastener chain C1 into a fastener chain C2 having a predetermined length, the lower transfer device 40 for transferring the cut fastener chain C2 downward, and the fastener chain C2 transferred by the lower transfer device 40 Is transferred by the second gripper 50, the slider mounting device 60 for attaching the slider S to the fastener chain C 2 transferred by the second gripper 50, and the second gripper 50. To the fastener chain C2 And the upper stopper part attaching device 70 for attaching the stopper part P1, the process until the continuous fastener chain C1 is cut into the fastener chain C2 having a predetermined length, and the slider S and the upper stopper on the cut fastener chain C2. The process until the part P1 is attached and finished into the slide fastener SF can be performed in parallel. Thereby, since the waiting time of the cutting device 30, the slider attaching device 60, and the top stopper attaching device 70 can be shortened, the assembly time of the slide fastener SF can be shortened.

Moreover, according to the slide fastener assembling apparatus 10 of this embodiment, since the slider attaching device 60 and the top stopper attaching device 70 are disposed below the cutting device 30, the length of the slide fastener assembling apparatus 10 is shortened. The slide fastener assembling apparatus 10 can be downsized.

Further, according to the slide fastener assembling apparatus 10 of the present embodiment, since the third gripper 80 for transferring the finished slide fastener SF to the right side in the width direction is provided, the completion of injection molding by the top stopper attaching device 70 is awaited. The second gripper 50 can be returned to the position for gripping the next fastener chain C2. Thereby, since the waiting time of the cutting device 30, the slider attachment device 60, and the top stopper attachment device 70 can be further shortened, the assembly time of the slide fastener SF can be further shortened.

In addition, this invention is not limited to what was illustrated to the said embodiment, In the range which does not deviate from the summary of this invention, it can change suitably.
For example, the third gripper 80 and the fourth gripper 90 may be eliminated, and the slide fastener SF may be discharged by the second gripper 50.
Further, instead of the fourth gripper 90 for discharging the slide fastener SF, the slide fastener SF may be discharged by a roll device including a driving roller and a guide roller.
