DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to a device for attaching a box bar to a stringer of a reverse opening slide fastener.

b. Prior Art Various proposals have been made regarding the automation of the production of conventional reverse-opening slide fasteners (for example, Japanese Patent Application Laid-open No. 1983
-85301, Japanese Patent Application No. 58-132095, etc.), when manufacturing reverse-opening slide fasteners, first insert a slider in the opposite direction to the normal slider into the stringer, and then attach the box bar. Due to problems with the stringer removal and box bar supply in the box bar attachment device, automatic finishing equipment for reverse-opening slide fasteners has not yet been realized, and conventionally, each metal fitting was attached using a dedicated machine. Currently, this is done manually.

c. Purpose of the Invention The present invention provides an efficient box bar mounting device that enables automatic finishing of reverse-opening slide fasteners and allows for easy and trouble-free feeding of box bars and removal of stringers inserted through sliders. The purpose is to

d Structure of the Invention The structure of the present invention is as described in the claims, in which the box rod holder is swingable for supplying the box rod and taking out the stringer, and the box rod holder holds the box rod. The hole is equipped with a lifting gate and a shutter to securely hold the box rod, and the locking lever of the die device opens the box rod holding hole widely to facilitate the removal of the stringer. To explain the present invention in more detail according to the illustrated embodiment, the reverse opening slide fastener includes a normal slider 3 and a slider 4 whose internal structure is reversed ( A reverse box slider) is attached to stringers 1 and 2, and one stringer 2
A butterfly pin 6 is attached to the tip of the stringer 1, and a box rod 5 with a stopper is attached to the tip of the other stringer 1.When attached to clothing, etc., the slide fastener can be opened by a slider from above or below. It has been made possible to do so.

Therefore, the device of the present invention for attaching the box rod of such a reverse opening slide fastener will be explained.
FIG. 1 is a side view showing a part of the box bar mounting device of the present invention in cross section.
0, a die device 25, and a box rod supply chute 23. It is pivotally supported by a rotating shaft 20 so as to swing between it and a die device 25 that caulks the rod. A box bar holding hole 14 for receiving and holding the box bar supplied from the supply chute 23 is formed between the tip of the box bar holder 10 and the box bar holding member 13. As shown in FIG. 2, two fasteners are provided at positions corresponding to the left and right stringers so that either right-handed or left-handed reverse opening slide fasteners can be manufactured. The box rod holding hole 14 has a lifting gate 12 on the side where the stringer is inserted.
A shutter 15 is provided on the side where the box bar is supplied, and the box bar is held between the two to prevent the box bar from falling or moving when the box bar is supplied and the stringer is inserted. It is configured to be set in a predetermined position. Lifting gate 12
is provided on the box rod holding member 13 so as to be freely retractable by means of a spring, and its tip is inclined so as to guide the stringer S to be inserted. As shown in FIG. 3A, the shutter 15 is provided with a box rod insertion hole 16 that communicates with the box rod holding hole 14 during supply, and is always biased by a compression spring 22 in the direction of closing the hole. There is. In the center of the shutter 15, there is provided an inclined part 21 that engages with the tip of a press pin 18 that is pressed against the base 24. The rod holding hole 14 and the box rod insertion hole 16 are configured to communicate with each other. Further, a stopper 17 that engages with the box bar holding member 13 is provided near the tip of the shutter 15 in order to maintain the wide open state of the box bar holding hole 14.
This stopper 17 is configured to come into contact with the base 24 and come off before supplying the box bar, and return to the original state of the box bar holding hole 14 by a spring provided in the box bar holder 10. A notch punch 11 is slidably provided inside the box bar holder 10 in order to make a notch at the same time when caulking the box bar. Below the box bar holder 10 is a die device 2.
5 is provided, and when the rod member attachment part 9 of the stringer S is inserted into the box rod in the box rod holding hole 14, it rises and presses the box rod holding member 13 to caulk the box rod. The die device 25 is provided with a locking lever 26, which engages with the engaging portion 19 of the box bar holding member 13 when the die device 25 is raised, and lowers the box bar holding member 13 when the die device 25 is lowered. In this way, the box bar holding hole 14 is opened widely to facilitate the removal of the stringer S to which the box bar has been attached.

Next, to explain the order in which the box rods are attached to the stringer, Figure 3 A, B, C, and D show the state at each stage. The bar holder 10 rotates to the position of the supply chute 23, and the stopper 17 and press pin 18 come into contact with the base 24, and the stopper 1
7 is removed and the box rod holding hole 14 returns to its original state.
Then, the shutter 15 was pressed by the press pin 18 and moved to the right, the box rod insertion hole 16 and the box rod holding hole 14 communicated, and the box rod was supplied from the supply chute 23 into the box rod holding hole 14. By the way. At this time, the box bar is prevented from falling by the lift gate 12.

Figure 3 B shows box rod holder 1 with box rods supplied.
0 returns to the mounting position, and the shutter 15 pushes up the press pin 18 that has come off the base 24 by the force of the compression spring 22, moves it to the left, closes the communicating hole, and holds the box rod. At this point, the tip of the inserted stringer S has returned to the position where it is stopped. Then, the stringer S moves forward and is inserted into the box bar, and the die device 25 rises and presses the box bar holding member 13 to caulk the box bar. At the same time, by means not shown, the notch punch 11 is
lowers and attaches a notch to the box rod to prevent it from falling off.

FIG. 3C shows that after the box bar has been crimped, the die device 25 is lowered, the box bar holding member 13 is pulled down by the locking lever 26, the box bar holding hole 14 opens wide, and the stopper 17 is moved to hold the box bar. The opening state has been set by engaging the member 13. Note that the locking lever 26 is disengaged from the locking portion 19 of the box rod holding member 13 as the box rod holder 10 rotates.

FIG. 3 D shows that the box bar holder 10 is connected to the box bar holding hole 1.
4 is swung in the direction of the chute 23 while keeping it wide open, and the stopper 17 has just come into contact with the base 24. At this time, the stringer to which the box bar has been attached is taken out from the wide opening of the box bar holding hole 14. Since the lifting gate 12 is also lowered together with the box rod holding member 13, it does not become a hindrance to taking out the box. Further, the box bar holder 10 rotates, and the press pin 18 comes into contact with the base 24 and is pressed, resulting in the state shown in FIG. 3A.

By repeating the above operations, the box bars can be attached to the stringer continuously.

e Effects of the Invention The present invention provides a lift gate before inserting the stringer in the box bar holding hole of the box bar holder and a shutter on the box bar supply side to hold the box bar in the box bar holding hole. The box rod can be supplied and installed reliably, and the box rod holder can be swung to the opposite side from the stringer insertion side, so the stringer can be inserted after the box rod has been installed, regardless of the slider inserted. The box bar can be easily taken out from the box bar holder and the box bar can be supplied at the same time, which further improves work efficiency and can be easily incorporated into the stringer finishing line. This is extremely significant as a device that makes it possible to realize a finishing device.
