Description

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 reverse-opening slide fasteners (for example, Japanese Patent Application Laid-Open No. 56-85301
When manufacturing reverse-opening slide fasteners (Japanese Patent Publication No. 58-1 '52095, etc.), in order to first insert a slider in the opposite direction to a normal slider into a stringer, and then attach a box bar. However, there are problems with stringer removal and box bar supply in the box bar attachment device, and automatic finishing equipment for reverse-opening slide fasteners has not yet been realized. At present, it is done manually using a method.

C2 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 provide

d6 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 stringer is characterized in that the hole is provided with a lifting gate and a judgment gate 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 6 and a slider 4 whose internal structure is reversed, as shown in FIG. (reverse phase slider) is attached to stringers 1 and 2, an insert pin 6 is attached to the tip of one stringer 2, and a box bar 5 with a stopper is attached to the tip of the other stringer 1. When attached to clothing, etc., the system slide zipper can be opened from above or below using a slider.

Therefore, to explain the device of the present invention for attaching the box bar of such a reverse opening slide fastener, Fig. 1 is a side view showing a part of the box bar attaching device of the present invention in cross section. Consisting of a bar holder 10, a die device 25, and a box bar supply chute 23, the box bar holder 10 is connected to the box bar supply chute 23 of a box bar parts feeder provided above the outlet on the opposite side to the insertion path of the stringer 8. , and a die device 25 for caulking the box rod. A box bar holding hole 14 for receiving and holding the box bar supplied from the supply chute 25 is formed between the tip of the box bar holder 10 and the box bar holding member 13. Two numerals 14 are provided at positions corresponding to the left and right stringers, as shown in FIG. 2, so that either a right-handed or left-handed reverse opening slide fastener can be manufactured. The box bar holding hole 14 is provided with a lifting gate 12 on the side where the stringer is inserted and a shutter 15 on the side where the box bar is supplied. The box bar is configured to be set at a predetermined position so that it will not fall or move when supplying the stringer and inserting the stringer. The elevating gate 12 is provided on the box rod holding member 13 so as to be freely protrusive and retractable by a spring, and its tip is inclined so as to guide the stringer 8 to be inserted. Shutter 15
As shown in Figure 5 (Ino), the box rod holding hole 1 is
A box rod insertion hole 16 communicating with the box rod insertion hole 16 is provided and is always biased by a compression spring 22 in a direction to close the hole.

In the center of the shutter 15, there is an inclined part 21 in which the tip of the press pin 18 that is pressed against the base 24 engages.
is provided, and the shutter 15 is moved by being pushed by the press pin 18, so that the box rod holding hole 14 and the box rod insertion hole 16 communicate with each other. Further, a stopper 17 that engages with the box bar holding member 16 is provided near the tip of the shutter 15 in order to keep the box bar holding hole 14 wide open. When the box bar holder 10 comes into contact with the base 24 and comes off, a spring provided in the box bar holder 10 returns the box bar holding hole 14 to its original state. Inside the box bar holder 10,
A notch punch 11 is slidably provided in order to make a notch at the same time as the box bar is caulked. A die device 25 is provided below the box bar holder 10, and a die device 25 is installed on the box bar in the box bar holding hole 14.
When inserted, it rises and presses the box bar holding member 16 to caulk the box bar. A locking lever 26 is attached to the die loading amount 25.
is provided so that when the die device 25 is raised, it engages with the engaging portion 19 of the box bar holding member 13, and when the die device 25 is lowered, the box bar holding member 13 is lowered to open the box bar holding hole 14. The stringer 8 is configured to have a wide opening and to facilitate the removal of the stringer 8 after the box rod has been installed.

Next, I will explain the order of adding box sticks to the stringer.
Figures 6 (a), (b), (c), and ii) show the state at each stage at this time, and Figure 3 (ino) shows the state at each stage.

In order to replenish the box rods, the box rod holder 10 is connected to the supply shoe.
) The stopper 17 and the press pin 18 come into contact with the base 24 as it rotates to the position 23, the stopper 17 comes off first, the box rod holding hole 14 returns to its original state, and then the shutter 15 comes into contact with the press pin 18. It is pressed and moved to the right, the box rod insertion hole 16 and the box rod holding hole 14 communicate with each other, and the box rod is supplied from the supply chute 23 into the box rod holding hole 14. At this time, the lifting gate 12 prevents the box rod from falling.

In FIG. 3(B), the box bar holder 10 with the box bars supplied returns to the mounting position, and the shutter 15 is moved by the compression spring 2.
The force of 2 pushes up the press pin 18 that has come off the base 24, moves it to the left, closes the communicating hole, holds the box bar, and stops the tip of the inserted stringer 8. I just returned to . and stringer
8 is advanced and inserted into the box bar, and the die device 25 rises and presses the box bar holding member 15 to caulk the box bar. At the same time, the notch punch 11 is lowered by means not shown to form a notch in the box bar to prevent it from falling off.

Figure 6 (c) shows the die device 2 after the box rod has been crimped.
5, the box bar holding member 13 is pulled down by the locking lever 26, the box bar holding hole 14 opens widely, and the stopper 17 engages with the box bar holding member 13 to set the open state. It comes off.

In FIG. 5), the box bar holder 10 swings in the direction of the chute 23 with the box bar holding hole 14 wide open, and comes into contact with the stopper 171fi base 24. At this time, the stringer whose box bar has been attached is taken out through 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 an obstacle to taking out the box. Furthermore, 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. 3(A).

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

e9 Effects of the Invention The present invention provides a lift gate on the stringer insertion side of 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 rods can be supplied and installed reliably, and the 5-box rod holder can be swung to the opposite side from the stringer insertion side.

Therefore, regardless of the slider inserted, the stringer with the box bar attached 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. with stringer
Since the present invention can be easily introduced into finishing lines, it is extremely meaningful as a device that enables the realization of an automatic finishing machine for reverse-opening slide fasteners.
