Description

[Detailed Description of the Invention] The present invention relates to an automatic sewing device that automatically feeds sewing material into a sewing machine body and performs sewing.

Conventionally, this type of automatic sewing device installed the main body of the sewing machine on a horizontal sewing machine table, fed the sewing material onto the sewing machine table one by one, and sewed the material while automatically feeding it using the feed mechanism and sewing needle mechanism of the sewing machine main body. However, since the sewing machine table is horizontal, the sewing material fed onto the sewing machine table does not move smoothly, and its positioning with respect to the sewing machine body tends to be uncertain, resulting in misalignment of the sewn part and damage to the product. Because the yield of
Full automation was not possible because positioning had to be done manually.

SUMMARY OF THE INVENTION The present invention has been devised in view of the above, and an object of the present invention is to provide an automatic sewing device in which the sewing material can be reliably positioned relative to the sewing machine main body with a simple configuration.

That is, in the present invention, the sewing machine table is installed at an angle of inclination, and the sewing machine body is placed at the lower part of the slope of the sewing machine table so that the sewing direction is horizontal to the inclination angle, and the sewing machine body is placed on the sewing machine table. A fixed guide is installed under the sewing mechanism section of the machine in the same direction as the sewing direction, and a slide plate placed on the sewing machine tape and movable in the same direction as the sewing direction serves as the fixed guide. Set the side guide on the slide plate in a direction almost perpendicular to the fixed guide, slide the sewing material on the slide plate, make it contact the fixed guide and the side guide, and position and set it with respect to the sewing machine body. This is how it was done.

An embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 shows a side view of the automatic sewing device according to the present invention. In Fig. 1, 1 is the sewing machine body, and the sewing machine table is installed on the machine base 2 at a required angle (45° in this example). 3, it is arranged so that the sewing direction is in the horizontal position. The lower part of the sewing machine table 3, that is, the sewing mechanism section 1 of the sewing machine main body 1
A fixed guide 4 is installed in the lateral direction near the lower side of a.

Then, the sewing material a fed onto the sewing machine table 3 slides along the slope of the sewing machine table 3,
It is received by a fixed guide 4 and positioned relative to the sewing machine main body 1.

In FIG. 2, reference numeral 5 denotes a slide plate which is placed on the sewing machine table 3 and whose lower edge abuts against the fixed guide 4 so that it can slide in the lateral direction. A side guide 6 and an auxiliary guide 7 are arranged on the side in a direction substantially perpendicular to the fixed guide 4, and a recess 9 is formed in the center of the lower side to escape the sewing mechanism section 1a of the sewing machine body 1. has been done.

The slide plate 5 is configured to be slid by a cylinder 8 to set the positions of the side guide 6 and the auxiliary guide 7 relative to the sewing machine main body 1.

That is, by installing this slide plate 5 on the sewing machine table 3, the lower edge of the sewing material a fed onto the sewing machine table 3 comes into contact with the fixed guide 4 while being placed on the slide plate 5. Once positioned, the slide plate 5 is slid by the cylinder 8, and the side guide 6 or the auxiliary guide 7 is brought into contact with the side edge of the sewing material a, thereby positioning the side.

FIG. 3 is a plan view of a state in which the automatic sewing device according to the present invention is combined with a sewing material conveying device;
In FIG. 3, reference numeral 11 indicates the entire material conveyance device, and reference numeral 12 indicates a material accumulation and mounting table installed adjacent to the sewing machine table 3. A rotating shaft 13 is attached to the side adjacent to the sewing machine table 3 in the vertical direction. An arm 14 is horizontally fixed to the upper end of the rotary shaft 3, and a cylinder 15 is fixed to the tip of the arm 14 with its cylinder rod 16 facing downward.
Then, a suction port body 17 is attached to the cylinder rod 16, and a suction device 18 is attached to the suction port body 17.
The rotary shaft 13 is connected via a belt 21 and pulleys 22, 23 and rotated by a motor 20 mounted on the lower surface of the mounting table 12.

The material conveying device 11 configured as described above first rotates the rotary shaft 13 by the motor 20 and transfers the suction port 1 onto the material a that is piled up on the mounting table 12.
7 are placed facing each other, and in this state, the cylinder 15 is operated to lower the suction port body 17 by the cylinder rod 16, and the suction ports 17a and 17b are brought into contact with the material a. Next, the suction device 18 is operated to adsorb the material a to the suction ports 17a and 17b, and the cylinder 1
5, the suction port body 17 is raised while holding the material a.

In this state, the rotating shaft 13 is rotated by the motor 20 at 180 degrees.
The suction port body 17 is moved onto the sewing machine table 3 by rotating the cylinder 15, and is lowered by the operation of the cylinder 15 to stop the operation of the suction device 18, so that the material a attracted to the suction port body 17 is transferred to the sewing machine table 3. It is dropped and placed on top.

Each of the above operations is performed continuously by setting a timer. Further, the positioning of the suction port body 17 with respect to the material a is performed by sensing it with a limit switch (not shown).

The material a thus dropped and placed on the sewing machine table 3 slides on the sewing machine table 3 and comes into contact with the fixed guide 4, and is automatically positioned with respect to the sewing machine main body 1.

In the above embodiments, the constituent members of each mechanism are not limited to those shown in the drawings, but may be of any construction as long as they can perform the operations described above.

As described above, in the device of the present invention, a sewing machine table is installed inclined at a required angle, the sewing machine body is placed at the bottom of the inclination so that the sewing direction is horizontal to the inclination angle, and the sewing machine body is placed on the sewing machine table. A fixed guide is installed under the sewing mechanism section of the machine in the same direction as the sewing direction, and a slide plate placed on the sewing machine table and movable in the same direction as the sewing direction serves as the fixed guide. Since the side guides are installed in a direction substantially perpendicular to the fixed guide on this sliding plate, the sewing material being transported and placed on the sewing machine table slides on the sliding plate and is connected to the fixed guide and the side guide. The material comes into contact with the guide and its position is regulated in two directions: the lower edge and the side edges, and the material is securely positioned and set, and even deformed sewing material can be stably and smoothly transferred by sliding the slide plate. Full automation of sewing work becomes possible. Also, in the configuration, the sewing machine table is tilted at a required angle, and a fixed guide is installed along the sewing direction of the sewing machine body installed at the lower part of the slope of the sewing machine table, and a slide plate with side guides installed is arranged. Since the structure is simple, the number of parts is small, manufacturing is simple, and it can be provided at low cost.
