Since the second guide block 56 is provided on the fixed plate 54, the second guide rail 57 is guided so as to be movable in the front and back direction of the fastener chain C with respect to the second guide block 56. Therefore, in this embodiment, the second guide rail 57 serves as a movable element. In addition, the movable plate 55 is fixed to the second guide rail 57 as the movable element as described above. It is the operation part 58 that moves the roller unit device 28 in the front and back direction of the fastener chain C via this movable plate 55.

The operating part 58 is a screw pair as shown in FIGS. 1 and 2. The screw pair here is an operating bolt 59 formed with an external thread, and a movable nut 61 fixed to the movable plate 55 by welding or the like and formed with an internal thread screwed with the external thread.

The operation bolt 59 includes a head part 59a as a gripper and a shaft part 59b protruding from the head part 59a.

A male screw (reference numeral is omitted) is formed on the outer peripheral surface of the shaft portion 59b. In addition, a through hole 55 b through which the shaft portion 59 b penetrates in the front and back direction of the fastener chain is formed in the movable plate 55.

The movable nut 61 is fixed to the movable plate 55 so that the threaded hole of the movable nut 61 communicates with the through hole 55 b of the movable plate 55.

In addition, if the head 59a of the gripper of the operating bolt 59 is rotated, the tip of the shaft 59b remains in contact with the fixed plate 54 and rotates, so the position of the shaft 59b of the operating bolt 59 relative to the fixed plate 54 does not change. . On the other hand, with the rotation of the shaft portion 59b of the operation bolt 59, the movable nut 61 is to be rotated together. However, the movable plate 55 fixed to the movable nut 61 is prevented from rotating by the combination of the second guide rail 57 and the second guide block 56 forming a pair with each other. As a result, inside the movable nut 61, the shaft portion of the operation bolt 59 rotates, the movable nut 61 moves relative to the shaft portion 59b in the front or back direction of the zipper chain C, and is fixed to the movable plate 55 of the movable nut 61 and then rolls The column assembly device 28 moves in the back or front direction of the zipper chain C. Since the roller assembly device 28 includes the guide roller 29 and the reference rollers 13a, 13b, the guide roller 29, the reference rollers 13a, 13b move toward the front or back of the fastener chain C along with the rotation of the operating bolt 59 Move and set the position to guide the zipper chain C.

The fastener chain C after passing through the above-mentioned first polishing part 2 faces the second polishing part 3.

The second polishing part 3 polishes the other of the front and back surfaces of the pair of element rows E and E of the fastener chain C after passing through the first polishing part 2. That is, the second polishing part 3 has the same structure as the first polishing part 2 except that the surface to be polished is different from the first polishing part 2.

The delivery unit 4 includes a driving roller 4a and a driven roller 4b that are rotationally driven. In addition, the delivery portion 4 sandwiches the fastener chain C between the drive roller 4a and the driven roller 4b, and delivers the fastener chain C to the storage portion 5 by the rotational drive of the drive roller 4a.

The storage part 5 is a housing 5 which stores the fastener chain C inside.

The polishing device of the fastener chain of this embodiment mentioned above has the following effects. In the first polishing part 2 and the second polishing part 3, in the polishing device of the zipper chain of the present embodiment, the rotation axis 11L of the polishing wheel 11 is along a direction that crosses a straight line parallel to the rotation axis 29L of the guide roller 29 ( More specifically, it extends in the orthogonal direction), so the direction different from the longitudinal direction of the pair of element rows E and E is set as the tangential direction of the grinding wheel 11.

In addition, in the zipper chain grinding device of this embodiment, the two grinding wheels 11, 11 of the grinding wheel device 7 respectively grind one surface of the front and back of the zipper chain C twice for each grinding wheel 11, so they are combined with one grinding wheel 11 Compared with a polishing device that only polishes once, the polishing quality is improved.

In addition, since the polishing device of the zipper chain of the present embodiment includes the guide roller 29, the guide roller 29 prevents the zipper chain C passing between the pair of reference rollers 13a, 13b from being pressed into the grinding wheel 11 and bending.

In more detail, since the zipper chain polishing device of the present embodiment sets the tangential direction of the polishing wheel 11 to the direction orthogonal to the longitudinal direction of the pair of element rows E, E, assuming that there is no guide roller 29, When the pair of element rows E, E are ground by the grinding wheel 11, the pair of element rows E, E laid between the pair of reference rollers 13a, 13b will bend, and the pair of element rows E, E is only in contact at both ends of the grinding wheel 11 in the thickness direction, and does not contact at the middle part of the grinding wheel 11 in the thickness direction. However, the zipper chain polishing device of this embodiment includes a guide roller 29 between the pair of reference rollers 13a, 13b, and the guide roller 29 prevents the pair of element rows E, E from being bent by the grinding wheel 11. Since it works, the quality of polishing is improved compared to a case where polishing is performed without the guide roller 29. Furthermore, since the polishing device for the fastener chain of the present embodiment includes a plurality of guide rollers 29 spaced apart along the conveying direction of the fastener chain C, compared with the polishing device provided with one guide roller 29, the polishing wheel 11 The number of places to hold the pair of element rows E and E increases, so the quality of polishing improves.

In addition, since the polishing device for the fastener chain of this embodiment includes the connecting device 26 that connects the guide roller support portion 31 and the reference roller support portion 16 in each polishing section, the connecting device 26 acts on the elastic member 37 The guide roller 29 is pressed into the grinding wheel 11 side via the support portion 31 for the guide roller. In addition, the distance between the grinding wheel 11 and the guide roller 29 of the zipper chain grinding device of this embodiment changes in accordance with the change in the thickness of the pair of element rows E, E, compared to the grinding wheel 11 and the guide roller 29. In the polishing device in which the interval between the rollers 29 is fixed, the contact between the polishing wheel 11 and the pair of element rows E and E is constant, and the quality of polishing is improved.
