Next, the zipper tape 27 of the first zipper chain 2A located on the conveying line L is gripped by the socket body side clamp 40A, and the zipper tape of the second zipper chain 2B located on the conveying line L is gripped by the plunger side jig 40B and the downstream jig 40C 27.

Next, after moving the socket body side jig 40A in the X-axis direction to the conveying downstream side by the jig moving device, the socket body side jig 40A is moved in the Y-axis direction and arranged to the left of the opening tool assembly position P1. At this time, the first zipper chain 2A moves in the conveying direction A due to the movement of the socket body side clamp 40A, and is arranged in the opening assembly by abutting the bottom surface 214 of the socket body 21 with the bottom bearing surface 54 of the bottom carrier 55 Location P1. At the opening assembly position P1, the lower surface 212 and the left and right side surfaces 213 of the socket body 21 abut the lower bearing surface 51 and the left and right side bearing surfaces 52 of the lower supporting body 53, and the socket is shown in FIGS. 3 and 4 The body 21 is in a state of being held by the socket holding device 50. On the other hand, the plunger side jig 40B and the downstream side jig 40C are moved to the downstream side of the conveyance in the X-axis direction and retreated to the right away from the conveying line L in the Y-axis direction by a jig moving device not shown. The plunger side jig 40B is arranged to the right of the opening tool assembly position P1. The downstream jig 40C is located on the conveying downstream side with respect to the plunger side jig 40B. At this time, as shown in FIG. 5, the plunger 25 is arranged on the right with respect to the socket body 21.

Next, the plunger side jig 40B and the downstream side jig 40C are moved by the jig moving device along the arrow M1 shown in FIG. The body side jig 40A side) advances and is arranged at the plunger insertion preparation position shown in FIG. 6. At this time, the position of the insertion end of the plunger 25 is opposed to the opening of the plunger insertion port 215 shown in FIG. 5. In addition, the part of the second zipper chain 2B on the downstream side of the conveyance compared to the plunger 25 is lifted to a position higher than the part on the upstream side of the conveyance by the downstream clamp 40C, and is moved by the downstream side. The aforementioned movement of the clamp 40C to the upstream side of the conveyance is arranged on the upper surface 211 of the socket body 21 as shown in FIGS. 4 and 6.

Next, the pressing surface 61 of the socket pressing body 60 is brought into contact with the upper surface 211 of the socket body 21 to suppress the socket body 21 from floating upward. Thus, the socket body 21 is sandwiched between the socket pressing body 60 and the lower carrier body 53. At this time, the part of the second zipper chain 2B arranged on the upper surface 211 of the socket body 21 is arranged in the chain avoiding space 65 as shown in FIG. 4, so this part will not be sandwiched between the socket pressing body 60 and the socket body 21, the movement resistance with respect to the second zipper chain 2B is generated.

In addition, the plunger guide member 80 descends from its raised position to the lowered position by the rotation in the rotation direction R, and the lower part of the plunger guide member 80 is arranged on the left and right sides with respect to the plunger 25 arranged as shown in FIG.

In addition, by the above movement, the portion of the second zipper chain 2B disposed on the upper surface 211 of the socket body 21 also moves to the conveying downstream side while passing through the chain escape space 65, and is drawn out from the upper surface 211.

As described above, the opening member 20 is combined by the opening member assembly device 1.

Next, the connection operation of the fastener element 22 comrades after combining the opening tool 20 is demonstrated. First, the bottom carrier 55 is lowered, and the first zipper chain 2A and the second zipper chain 2B are brought into a state that can be conveyed in the conveying direction A by the conveying device 30. Here, in the connection device 70, the movable body 71 is raised in conjunction with the lowering of the bottom carrier 55 by the lever mechanism 73, and the pair of left and right element guides 72 are shown from the bottom as shown by the two-dot chain line in FIG. The guide surface 531 of the carrier body 53 protrudes upward.

After being in this state, the first zipper chain 2A and the second zipper chain 2B are conveyed in the conveying direction A by the conveying device 30, so that the left and right zipper element rows 23 pass between the left and right element guides 72 In the Y-axis direction, they are close to each other, and the left and right fastener elements 22 are sequentially meshed with each other. In addition, the plunger guide member 80 can be moved to the ascending position, and it can also be used for the meshing operation of pressing and meshing the fastener element 22 from above.

[Effects of this embodiment]

(1) In this embodiment, the gripping position of the downstream jig 40C with respect to the second fastener chain 2B is set to a position higher than the gripping position of the plunger side jig 40B with respect to the second fastener chain 2B by a predetermined amount or more. Specifically, the holding position by the downstream jig 40C is set to a higher position than the holding position by the plunger side jig 40B, and is set to be higher than the position where the pressing surface 61 abuts the upper surface 211 of the socket body 21 Location.

Therefore, when the second zipper chain 2B is temporarily moved to the upstream side of the conveyance in order to insert the plunger 25 into the socket body 21, although the part of the second zipper chain 2B located on the downstream side of the conveyance compared to the plunger 25 also moves toward The socket body 21 side moves, but since the holding position by the downstream jig 40C is set to a higher position as described above, this part can be avoided to the upper side of the socket body 21, so that the second zipper chain 2B and the socket can be reduced. The body 21 interferes. Therefore, it is possible to smoothly combine the opening tool 20 while suppressing the operation stoppage caused by the poor combination of the opening tool 20.

In addition, even if the size of the spacer 26 formed in the first zipper chain 2A and the second zipper chain 2B in the X-axis direction is reduced to reduce wasted material, the second zipper chain 2B is prevented from facing the socket body 21 as described above. The interference can also smoothly assemble the opening piece 20.

In the socket pressing body 60 at least on the other side of the left and right sides in the Y-axis direction with respect to the pressing surface 61, a chain escape space 65 is formed. In the chain avoidance space 65, a part of the second zipper chain 2B located on the conveying downstream side of the plunger 25 can be arranged.

Therefore, when the second zipper chain 2B is temporarily moved to the upstream side of the conveyance in order to insert the plunger 25 into the socket body 21, although the part of the second zipper chain 2B located on the downstream side of the conveyance compared to the plunger 25 also moves toward The socket body 21 moves, but this part can be arranged in the chain avoiding space 65 at the other side of the pressing surface 61, so that interference between the second zipper chain 2B and the socket body 21 or the socket pressing body 60 can be reduced. Condition.

(3) The chain avoidance space 65 is formed in the socket pressing body 60 so as to be continuous from a position on the other side of the left and right sides with respect to the pressing surface 61 to the conveying downstream side. Therefore, although the part held by the downstream clamp 40C in the second zipper chain 2B is lifted to a position higher than the upper surface 211 of the socket body 21, and is conveyed to the conveying downstream side after the opening member 20 is assembled, the The second zipper chain 2B can be directly passed into the chain avoiding space 65, so the second zipper chain 2B can be smoothly conveyed without interfering with the socket pressing body 60.

(4) The plunger side jig 40B and the downstream side jig 40C are installed in the opener assembly 1 so as to be able to advance and retreat in the Y-axis direction. The chain avoidance space 65 is formed by the raised avoiding side surface 62 and the avoiding bottom surface 63 extending from the avoiding side surface 62 to the left and right sides. The corner portion 64 formed by the avoiding side surface 62 and the avoiding bottom surface 63 can be chamfered. . In the case of a chamfered shape like this, the plunger side jig 40B and the downstream side jig 40C holding the second zipper chain 2B are moved to the upstream side of the conveying, and then they are advanced to the left and right, and then the By moving to the downstream side of the conveyance, the plunger 25 can be inserted into the socket body 21. In addition, when advancing the plunger side jig 40B and the downstream side jig 40C to the left and right, the second zipper chain 2B can be guided downward by the corner portion 64 having a chamfered shape as described above.
