Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic saddle stitching device for a cushion, and more specifically, an operator can saddle-stitch the cushion at the center of the cushion only by supplying and placing the cushion at a predetermined position. The present invention relates to an automatic saddle stitching device capable of continuously and efficiently saddle stitching a large number of cushions.

[0002]

2. Description of the Related Art Generally, in cushions containing cotton or the like, in order to prevent misalignment of the filled cotton or the like and to add a decorative effect, Japanese stitching at the four corners of the cushion and saddle stitching at the central portion are performed. What you have done is widely known.

However, at the stage of Japanese stitching, Japanese stitching can be performed on the four corners of the cushion by the Japanese stitching sewing machine, but when performing saddle stitching, the expansion of the central portion is suppressed by the filled cotton or the like. Since it is necessary to pass the sewing needle in the vertical direction, sewing machines such as sewing machines cannot be used, and saddle stitching was performed exclusively by hand sewing.
Perhaps because the burden on the operator involved in saddle stitching is increased and efficient saddle stitching cannot be performed, the pressure to suppress the expansion of the central portion does not become constant for each cushion, but the central portion of the cushion by saddle stitching The shape of the dents varies, and the texture and decorative effect of the cushion after the product is completed are different, so that it is not possible to secure a certain quality as a product.

[0004]

SUMMARY OF THE INVENTION In view of the above situation, the present invention has been made to eliminate the conventional drawbacks, and the purpose thereof is to place a cushion on a predetermined position. It is possible to perform saddle stitching on a large number of cushions with only a very simple operation, and it is possible to significantly reduce the burden on the operator, improve the working environment, and efficiently obtain a cushion of uniform quality. An object of the present invention is to provide an automatic saddle stitching device for cushions that can be produced well.

[0005]

In order to solve the problems, the technical means adopted by the present invention is that, when saddle stitching is applied to the central portion of the cushion after Japanese stitching, the cushion is first pressed and compressed in the front and back directions. , A required number of suture thread passages to be inserted from one surface side of the cushion to the other surface side are punched in the central portion of the cushion in the compressed state, and then the suture threads are respectively inserted through the suture passage paths, and each suture thread is further inserted. After bundling with the upper and lower end surfaces of the compressed cushion, and cutting the extra length to a predetermined length,
It is characterized in that the pressed and compressed state of the cushion is released.

[0006]

Therefore, according to the present invention, when saddle stitching is performed on the cushion, the operator simply places the cushion on a predetermined position, and thereafter, the central portion of the cushion is automatically compressed by the pressing body, The saddle stitching work can be smoothly performed by punching holes in the central portion of the cushion, inserting the thread, and binding and cutting the threads on the upper and lower surfaces of the cushion without delay. Then, when the saddle stitching is completed, the compression of the cushion is automatically released, and the pressing body returns to the initial state. Therefore,
Even if a large number of cushions are used, the worker can efficiently perform saddle stitching continuously by merely placing the cushions at predetermined positions below the pressing body that have returned to the initial state.

(24) By the operation control of the above (1) to (23), after the center portion of the cushion a is saddle-stitched, the elevating cylinder 37 is operated to raise the pressing body 6a. (25) The pressed and compressed state of the cushion cushion a is released, and a dent due to the expansion of the batting is formed in the cushion cushion a around the saddle stitch position. (26) Each drive unit of the lower binding mechanism 4 and the upper binding mechanism 6 is returned to the initial state.

Therefore, by operating the automatic saddle stitching apparatus 1 as described above, when the automatic saddle stitching apparatus 1 returns to the initial state, the operator sequentially places the cushions a, a ... On the base 8. The cushion cushion a can be easily handled, and saddle stitching can be performed smoothly and reliably even with a large amount of cushion, and the labor of the worker can be reduced and the productivity can be improved.

[0024]

In summary, according to the present invention, when saddle stitching is applied to the central portion of the cushion after Japanese-sewn stitching, first, the cushion is pressed and compressed in the front and back directions, and then one side of the cushion is pressed to the other side. Sewing thread passages to be inserted into the surface side, perforated the required number of holes in the central portion of the cushion in the compressed state, then insert the thread through the thread passages, and bind each sewing thread with the upper and lower end surfaces of the cushion in the compressed state, After cutting the extra length portion to a predetermined length, the compression compression state of the cushion is released, so the sewing needle is passed vertically while pressing the expansion of the central part due to the filled cotton etc. This greatly reduces the burden on the worker in the past, and the saddle stitching can be performed on the central part of the cushion by only the extremely simple work of placing the cushion on the predetermined position, improving the working environment. While large It is possible to continuously and efficiently saddle-stitch the cushions, and to make the pressure to suppress the expansion in the central portion of the cushions uniform, and to keep the shape of the depression in the central portion of the cushions constant. Therefore, the quality of the cushion, the decorative effect, etc. after completion of the product can be uniformly maintained, and the variation as the product can be suppressed as much as possible, and a very useful new effect is exhibited. Is.
