In addition, the fabric mounting table has a pair of left and right sewing station sections, and the fabric mounting table has a pair of left and right sewing stations. At the rear of the sewing machine, the machine frame is provided in a manner that corresponds to each sewing station. A pair of left and right sewing machines are installed, and a fabric table is equipped with upper and lower sewing machines corresponding to each sewing station. It has a pair of left and right cloth clamping plates that are movable downwardly, and the sewing machine is Make sure that the longitudinal direction of the horizontal body of the stick is facing the front and back direction, and the needle is located at the front. Then, install the bed in the machine frame so that it goes under the cloth table. The needle passes through the cloth holding plate and the sewing station section of the cloth placement table. An opening is formed therein.

0004

[Effect of invention]

This idea works as follows. Fit and cover the cylindrical side wall of the container bag onto the cloth placement table, and Place the upper side of the peripheral wall on the sewing station. Then, attach the rope attachment piece to Place it on the sewing station section. After that, lower the cloth clamping plate that had been swinging upward until now. Then, fix the side wall and the rope attachment piece all at once using the cloth clamping plate. After making these preparations, move the fabric table from side to side and back and forth to make the left and right stitches. By driving the machine, two rope attachment pieces can be sewn automatically. Ru.

【Example】

This invention will be explained below based on embodiments shown in the drawings. In addition, in this specification , front means the bottom side of Figure 1, rear means the top side of the figure, left means the left side of Figure 1, and right means the left side of Figure 1. Refers to the right side of the figure. A fixed table 2 is attached to the front of the machine frame 1 so that its front part extends horizontally. A pair of left and right sewing machines 4 are provided on the left and right sides of this fixed table 2, and a bed 5 thereof is installed. It is buried and fixed so that the top surface is flush with the top surface of fixed table 2. . The sewing machine 4 is power connected to one motor (not shown), and the sewing machine 4 is powered by one motor (not shown). They are designed to operate synchronously with the rotation of a motor.

[0006] A back and forth movable table 10 is provided at the rear of the fixed table 2 of the machine frame 1 so as to be movable back and forth. A left-right movable base 11 is provided on this back-and-forth movable base 10 so as to be movable left and right. The fore-aft movement The table 10 and the left/right moving table 11 are a ball screw mechanism rotated by a motor, etc. It is adapted to be actuated by a known drive device (not shown) having a Ru.

[0007] A cloth mounting table 14 having a T-shaped planar shape is provided on the left-right movable table 11 . With this configuration, the cloth placing table 14 can be moved in any direction, front, back, left or right. It is done freely. Each of the left and right sides of the cloth placement table 14 is paired with the sewing machine 4. The sewing station section 15 is constructed as follows. Each of these sewing station sections 15 In each case, the cloth holding plate 17 frees the front end via a pivot 16 whose axis is oriented in the left-right direction. It is provided so that it can freely swing up and down so that it is at the end. The cloth holding plate 17 is It is adapted to be actuated by a cylinder 18. A needle passage opening 20 is formed in the cloth holding plate 17 and the sewing station section 15. There is.

[0008] A container bag is installed at the rear of the sewing station section 15 of the cloth placement table 14. Lifting mechanism operated by an air cylinder 22 that clamps and fixes only the side peripheral wall W1 of the A clamp 23 is provided.

[0009]

[Effect of the example]

Next, the operation of the embodiment device will be explained. First, the side peripheral wall W1 is fitted onto the front part of the cloth placement table 14, and the side peripheral wall W 1 is placed on the sewing station section 15. In addition, in this state, the side peripheral wall W The lower part of 1 has a large U shape below the cloth placing table 14 and fixed table 2. It is made to loosen in the shape of a letter. After that, the lifting clamp 23 that had been rising until now is lowered, and the side peripheral wall W1 is fixed to the cloth mounting table 14 by the lifting clamp 23. to be determined. Thereafter, the rope attachment piece W2 is attached above the needle passage opening 20 of the side peripheral wall W1. Place it on the other side. After that, the cloth holding plate 17, which had been swinging upward until now, is lowered. Then, fix the side peripheral wall W1 and the rope attachment piece W2 at once using the cloth holding plate 17. Ru. After such preparation, when the main switch (not shown) is turned on, the cloth placing table 14 moves to the sewing start position, the cloth presser lowers and the left and right sewing machines 4 start operating. At the same time as the sewing starts, the cloth placing table 14 moves back and forth and left and right to set a predetermined sewing pattern. The stitching is done. When the sewing is completed, the thread is cut and the fabric presser rises and the sewing machine 4 stops. After that, the side peripheral wall W1 is freed by an operation opposite to the above preparatory work, and the remaining The two rope attachment pieces W2 are sewn in the same manner as described above.

0010 Note that in this specification, cloth includes all flexible sheet-like members. It is.

[0011]

[Effect of the idea]

This invention has the following effects due to the above-mentioned configuration. . According to this invention, a hanging rope is attached to the cylindrical side wall of a container bag. Automatically sews two of the four rope attachment pieces of the same shape at the same time. You can.
