The handle assembly device 100 of this structure supplies the handle 15 to the slider body 13 using the handle grip 60 shown in FIG. 2. At this time, with respect to the slider body 13 conveyed by the slider conveying path 17, the plate-like portion 71 of the guide member 69 is arranged at the center in the width direction orthogonal to the moving direction of the slider body 13. Accordingly, the large-diameter portion 59 of the handle shaft portion 57 is pressed by the recessed portion 75 of the plate-like portion 71.

FIG. 6 is a perspective view showing a positional relationship between the handle grip portion 60 and the flanged caulking portion 21 before the flanged caulking. Please refer to FIGS. 1, 3 and 6. Above the slider body 13 (not shown) stopped at the assembly position 23 of the slider conveying path 17, a pair of holding pieces 63 of the handle gripping portion 60, a guide member 69, and a crimped caulking punch 37 are arranged. Of punch 81.

In a state where the guide member 69 is in contact with the handle shaft portion 57, each of the punches 81 is inserted into the gap 83 between the plate-like portion 71 of the guide member 69 and the pair of holding pieces 63 by the lowering of the slider 24. Then, the leg 61 of the handle mounting post 39 of the slider main body 13 is crimped by using the lower end of each punch 81.

FIG. 7 (A) is a partial cross-sectional view showing a state where the handle 15 is sandwiched by a pair of holding pieces 63 and the guide member 69 is in contact with the handle shaft portion 57. FIG. Bottom view. The handle 15 is sandwiched by a pair of holding pieces 63 on both sides of the grip plate portion 51, and a recessed portion 75 formed on the pressing surface 73 of the guide member 69 abuts the large-diameter portion 59 of the handle shaft portion 57.

The recessed portion 75 fits into the outer periphery of the large-diameter portion 59 to position the handle shaft portion 57 with high accuracy in the up-down direction and the front-rear direction.

The handle 15 is conveyed from the handle supply portion 19 shown in FIG. 1 to the assembly position 23 in a state of being held by the pair of holding pieces 63 as described above. Then, the handle grip 60 is lowered toward the slider body 13 at the assembly position 23. The lowered handle grip portion 60 abuts the recessed portion 75 of the guide member 69 and the large-diameter portion 59 of the handle shaft portion 57 and presses the handle 15 toward the upper flap 41 of the slider body 13 shown in FIG. 3.

In this way, in addition to being held by one holding piece 63, the recessed portion 75 of the guide member 69 is pressed against the large-diameter portion 59 of the handle shaft portion 57, so that the handle 15 is accurately positioned at predetermined positions in the up-down, left-right, and front-back directions And, it can reliably maintain the positioning state. Therefore, it is possible to prevent the handle 15 from being displaced from the slider body 13.

Further, the slider body 13 is supplied with a handle 15 at an assembly position 23, and in this state, the handle mounting post 39 is directly bent and crimped to fix it. In other words, after the handle 15 is supplied, the slider main body 13 in a state where the handle is temporarily fixed is not conveyed along the slider conveying path 17. Compared with the method of conveying the slider main body in a state where the handle is temporarily fixed to the flanged caulking portion in order to cause the handle mounting column 39 to be crimped, there is no accidental occurrence of the handle, such as falling off or shifting. For example, when there is a production change adjustment that changes the type of the handle, the position of the center of gravity changes due to the thickness and shape of the handle, so that the handle becomes easy to shift or fall off from the slider body during transportation. However, the present invention is adopted. The structure does not occur this kind of bad situation.

Therefore, according to the handle assembly device of this structure, it is possible to easily handle a variety of handles, and it is possible to stably assemble the handles even with a small-sized slider, thereby improving productivity.

Hereinafter, the installation process of the above-mentioned pull handle 15 to the slider body 13 will be described in more detail. 8 (A) to 8 (C) are explanatory diagrams showing steps in a process until the handle supply unit 19 arranges the handle 15 on the slider body 13.

In the step of assembling the handle 15 to the slider body 13, as shown in FIG. 8 (A), the handle holding portion 60 clamps both ends of the handle shaft portion 57 with the V-shaped grooves 67 of the pair of holding pieces 63 (see FIG. 3). Shown on both sides of the grip plate portion 51 of the handle 15 shown). Then, the handle 15 is moved from the handle supply part 19 toward the assembly position 23 of the slider conveyance path 17.

As shown in FIG. 8 (B), the handle grip portion 60 is stopped directly above the slider body 13 which is waiting at the assembly position 23 on the slider transport path.

Next, as shown in FIG. 8 (C), the handle gripping portion 60 drives the slider 33 to lower the slider 33, and places the handle 15 held by the pair of holding pieces 63 on the upper wing plate 41 of the slider body 13. At this time, the handle shaft portion 57 of the handle 15 placed on the upper wing plate 41 is inserted into the mounting column portions 39A and 39B formed on the upper wing plate 41. That is, the handle shaft portion 57 is inserted between the pair of leg portions 61 and 61 of the mounting pillar portion 39A and between the pair of leg portions 61 and 61 of the mounting pillar portion 39B. At this time, the recessed portion 75 of the guide member 69 of the handle grip portion 60 maintains a state in which the large-diameter portion 59 of the handle shaft portion 57 is pressed toward the upper flap 41.

Next, the crimping step of the handle mounting post 39 will be described. 9 (A) to 9 (E) are explanatory diagrams showing steps in a process of assembling the handle 15 to the slider body 13. From the state shown in FIG. 8 (C), as shown in FIG. 9 (A), in a state where the guide member 69 presses the handle shaft portion 57, the flanged caulking punch is inserted into the gap 83 on both sides of the guide member 69. The punch 81 (see FIG. 5) of the head 37 drives the punch 81 downward.

As shown in FIG. 9 (B), while the punch 81 is lowered, the pair of holding pieces 63 is opened. Then, as shown in FIG. 9 (C), the punch 81 presses each pair of leg portions 61 formed on the mounting column portions 39A and 39B under a predetermined load. By this pressing, the paired leg portions 61 are deformed in a direction approaching each other, and the handle mounting post 39 is crimped and crimped. Thereby, the handle shaft part 57 is prevented from falling off from the mounting post parts 39A, 39B, and the handle 15 is assembled to the slider body 13. With the above processing, the assembly of the slider 11 is completed.

Next, as shown in FIG. 9 (D), the punch 81 is raised in a state where the pair of holding pieces 63 is opened. Then, as shown in FIG. 9 (E), the handle grip portion 60 is raised, and the depression of the handle shaft portion 57 by the guide member 69 is released. And the handle grip part 60 returns to the handle supply part 35 side from the assembly position 23 shown in FIG.

Then, the slider 11 in which the handle 15 is assembled is intermittently moved in the slider conveying path 17 toward the front in the conveying direction again, thereby conveying it to the next step.

According to the handle assembly device 100 configured as described above, when the handle 15 is supplied to the slider body 13, the handle 15 is stably held by the holding piece 63. In addition, when the leg portions 61 of the mounting column portions 39A and 39B are crimped by the punch 81, the handle shaft portion 57 is positioned on the slider body 13 by being pushed by the guide member 69. In addition, by opening the holding piece 63, the holding piece 63 does not interfere with the punch 81. Therefore, the handle 15 can be stably positioned on the slider body 13 and the positioning state can be maintained at all times. Therefore, the positioning accuracy of the handle 15 can be improved.

In addition, in a state where the handle 15 is positioned on the slider body 13, the handle mounting post 39 is directly crimped and crimped without being conveyed. Therefore, it is possible to reliably prevent the handle 15 from being shifted or detached from the slider body 13. In addition, a slider with poor assembly of the handle 15 is unlikely to occur, and productivity can be improved. Moreover, even when changing production, it is possible to easily cope with various handles 15. Even if a small-sized slider is assumed, the slider body 13 can be stably assembled.

In addition, according to the handle assembly device 100 of this structure, a pair of gaps 83 formed between the pair of holding pieces 63 and the guide member 69 are effectively used as the lifting space of the flanged caulking punch 37, which can be a space utilization High structure. Therefore, it is possible to perform space-saving and high-precision crimping.

Further, a recessed portion 75 formed in the pressing surface 73 of the guide member 69 is fitted into the large-diameter portion 59 of the handle shaft portion 57 and presses the handle shaft portion 57. Accordingly, even with a small-sized slider, the slider 15 can be stably pressed against the slider body 13, and the slider 15 can be positioned more reliably on the slider body 13.

In this way, the present invention is not limited to the above-mentioned embodiments.
