Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus for cutting a long slide fastener chain (hereinafter referred to as a fastener chain) into a predetermined length and then inserting the same into a slide.

Problems to be Solved by Prior Art and Invention Conventionally, in order to insert a fastener chain into a slide, the left and right ends of the fastener chain were aligned so that they were parallel, and this was grasped with hands to insert the fastener chain into the slide's narrow shoulder openings. I made sure to insert it correctly. Therefore, the worker had to concentrate on his/her hands and perform the work accurately.

Therefore, working efficiency was reduced and productivity was low.
In order to solve these problems, we have recently developed a “device for attaching a slide to a fastener chain.”
(Korean Patent Publication No. 79-1247) was proposed. This can automatically perform the slide guiding and gripping functions, but in the process of inserting the fastener chain into the slide, the end of the fastener chain is inserted into the slide and reaches the partition wall. Immediately before moving, both ends of the fastener chain must be pulled in the direction of travel while spreading them with appropriate force, and this requires extremely precise movement. This work is difficult to automate, and therefore the above work has to be done by hand in advance by an operator, which also poses the problem of not being able to improve productivity.

The present invention solves these problems and provides a slide fastener chain for a slide in which the process of cutting the fastener chain to a certain length and the process of inserting it into the slide can be automated with a simple structure. The object is to provide a device for insertion.

EXAMPLES The present invention will now be described in detail based on examples with reference to the accompanying drawings.

A fastener chain 2 is supplied at a constant speed by a supply reel 1, guided by a guide roller 3 and a guide plate 4, and cut into a predetermined length by a cutting blade 5 to guide the slide. and the slide is continuously supplied by the gripping device 6;
In a known device, a sensor 7 and a transmitter 7' are installed in front of a guide plate 4 so as to face each other on a vertical line, and in front of the sensor 7 and a transmitter 7', there are separated rollers having upper, lower, left and right rollers with different diameters. The roller 8 and its solenoids 9, 9' are disposed, and the space from below the sensor 7 to the limit switch 10 (FIG. 5) in front of the slide guiding and gripping device 6 is moved by a known reciprocating means 17 ( 6) so that the clips 11, 11' which are slid by the clips 11 and 11' move in semicircular trajectories that are symmetrical to each other.

Reference numeral 12 is a slide, 13 is a left and right element of a slide fastener, and 14 is an operating rod of a clip. Further, 16 is a roller for allowing the left and right clips 11, 11' to freely move according to the shape of the guide groove 15, and 18 is a roller for allowing the left and right clips 11, 11' to move freely according to the shape of the guide groove 15.
19 is the clip 11,
11' is the extension rod, 20 is the locus drawn by the fastener chain element, and 21 is the clip 11,1.
1' is the trajectory drawn by the tip, and 22 is the opening of both shoulders of the slide.

The operation of this embodiment of the present invention will be explained as follows.

First, by rotating the supply reel 1 on which the fastener chain 2 is wound, the fastener chain 2 is guided by the guide roller 3 and passes through the cutting blade 5 and the guide plate 4 to the sensor 7 and the transmitter. 7' position is reached. Then, the light or infrared rays emitted from the transmitter 7' is blocked on the way to the sensor 7, and the sensor 7 inputs the changed signal to a controller (not shown) to operate the solenoid 18. Then, the operating rod 14 is raised, and the left and right clips 11, 11' grip both sides of the fastener chain 2 in the state shown in FIG.

At the same time, the controller momentarily lowers the cutting blade 5 to cut the fastener chain 2. Then, the left and right clips 11, 11' are moved forward by the operation of a sliding reciprocating means such as a crank, a rack gear, or an air cylinder operated by a controller, and pass the separation roller 8. .

However, in the embodiment of the present invention, the diameters of the upper and lower and left and right rollers of the separation roller 8 are different, so the elements 13 on both sides of the fastener chain 2, which are engaged and fastened to each other, cannot move the separation roller 8. During the passage, it is disassembled and both sides of the fastener chain 2 are separated as shown in FIG.

After separating the fastener chain 2 to a certain width, the solenoids 9 and 9' are activated by the controller to raise the upper roller 9 and lower the lower roller 9' to sandwich both sides of the fastener chain 2. The current clips 11, 11' continue to move forward.

However, in the embodiment of the present invention, FIGS.
As shown in the figure, a roller 16 is loosely installed at the lower part of the extension rod 19 of the clip 11, 11' connected to the reciprocating means 17, and is guided by the guide groove 15 of the guide plate. In the end, the clips 11 and 11' move while drawing a semicircular locus that is the shape of the guide groove 15, and the distance between the clips 11 and 11' is expanded as shown in FIG. 5b. .

Then, as shown in Figure 5c, clip 1
The fastener chain 2 is fitted in a state in which the distance between the clips 1 and 11' is narrowed to match the forming angle θ of both shoulder openings 22 of the slide 12, and the clips 11 and 11' are moved in parallel. The controller receives the signal from the limit switch 10 and turns off the solenoids 18 of the clips 11, 11' and the solenoids 9, 9' for the separation rollers.
1 and 11' separate the two sides of the fastener chain that had been sandwiched between them, and the upper and lower separation rollers 8 are brought into engagement again. And the controller is connected to the clips 11,1
1' is returned to be located on the perpendicular line between the sensor 7 and the transmitter 7', and when the fastener chain that has passed through the guide plate 4 reaches there, the solenoids of the clips 11 and 11' are activated again by the activation of the sensor 7. 18 is activated to repeat the operations described above.

Further, the product with the fastener chain 2 inserted into the slide 12 is dropped downward by the controller, and at the same time, the product with the fastener chain 2 inserted into the slide 12
Of course, a known slide guiding and gripping device 6 continuously supplies the slide 2 for continued insertion.

As described above, in the embodiment of the present invention, in the process of cutting the fastener chain 2 to a predetermined length and expanding the fastener chain to the left and right in order to insert it into the slide 12, it is particularly easy to pull it to the left and right. Considering the characteristic of the fastener chain that does not spread out, the elements of the left and right fastener chains are inserted while the rollers with different diameters on the upper and lower and left and right sides are engaged, as shown in Fig. 4. In addition, the guide groove 15 is recessed in accordance with the forming angle θ of both shoulder openings 22 of the slide, and the fastener chain 2 is attached to the slide 12 at an angle that matches the forming angle θ of both shoulder openings 22 of the slide. can be pulled in, making the insertion work extremely smooth and quick.

Effects of the Invention In this way, the present invention provides that after the fastener chain is cut to a predetermined length with both side elements of the fastener chain fastened together, both sides of the fastener chain are The elements can be easily separated, and the fastener chain can be inserted accurately according to the forming angle of both shoulder openings 22 of the slide, making it possible to completely automate the process and greatly improve productivity. Therefore, it is useful because it can reduce cost and minimize defective rate.
