Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cloth feeding device for automatically feeding cloth to a cloth feeding jig of an automatic sewing machine.

[0002]

2. Description of the Related Art Conventionally, for automatically sewing a trim cover of an automobile seat with a sewing machine, for example, the actual machine shovel 54-7296 is used.
As disclosed in Japanese Patent Publication No. 6 and the like, a jig which is guided and fed by a guide roller is provided on the table of the sewing machine, and the fabric placed on the jig is fed into the sewing machine needle together with the jig. Some are automatically sewn.

It is necessary to set one or a plurality of cloths on the jig of this automatic sewing machine, and the operator manually performs this setting. That is, the cloth is manually taken out from the storage box and placed on the jig.

[0004]

Therefore, conventionally, since the cloth is manually set on the jig, the workability is poor. Therefore, it is an object of the present invention to automatically set the cloth on the jig.

[0005]

A cloth feeding device for a feeding jig of an automatic sewing machine according to the present invention for achieving the above object is a jig for placing a cloth on a table of the automatic sewing machine and feeding the cloth to the sewing machine. A device for supplying a large number of laminated fabrics to a storage part, which moves forward and backward and up and down to reciprocate on a jig from the storage part, and inside the storage part provided at the tip of the robot. A detector that detects the height of the cloth, a mounting plate that is horizontally mounted on the robot, and a pair of left and right chucks that are made of needle cloth and that are mounted horizontally below the mounting plate by a cylinder. It is composed of a pair of left and right pressing pieces that are vertically mounted on the mounting plate located outside the chuck to press the cloth.

[0006]

After the robot is lowered to press the cloth at the uppermost position in the storage unit and the pair of left and right chucks are horizontally moved outward respectively, the cloth is locked to the chucks. In that state, the robot arm is raised to carry the cloth on the jig, the robot arm is lowered on the jig to place the cloth on the jig, and the pressing section presses the cloth against the jig. Next, when the chucks are moved inward, the cloth comes off from the chucks. Then, when the robot arm is raised, the cloth is set on the jig.

The jig (71) is a guide rail (71A).
(71A) It is sent to the sewing machine (M) by a hydraulic cylinder or the like along the (71A) and the jig (7
1) The cloths (A) and (B) set on the top are sewn. When the jig (71) hits the stopper (77) after the sewing is completed, the hydraulic cylinder returns to the original position. In the figure (76) is a jig (7
1) A guide piece that presses the upper fabrics (A) and (B) to accurately feed it to the sewing machine needle, and is fixed to a standing piece (not shown) standing upright on the table (T).

Fixed guide pieces (72A) (72A) for positioning the fabrics (A) and (B) at predetermined positions on the jig (71) and around the jig (71). ) And movable guide pieces (73A) (73B) (73C), (7
4), a pressing piece (75) is provided.

The storage parts (6) and (6) are provided on the upper side and the jig (7).
1) is a box having an open side surface, and stores a large number of fabrics in a stacked manner in the vertical direction, and the one shown in the drawing stores fabrics (A) and (B) of the same shape. , One side of which stores the front side fabric (A), and the other side of which stores the front side fabric (B).

FIG. 2 shows the device (D) of the present invention. The robot (1) is a single-axis robot which moves vertically, and a table (T) which can be moved back and forth and left and right by a rodless cylinder as described above. It is suspended from a pillar (not shown) provided in the. A mounting plate (4) is horizontally mounted on the robot (1), and a detector (5) and a pair of left and right chucks (31) are mounted on the mounting plate (4).
(31), pressing pieces (22), (22) are provided.

The mounting plate (4) is moved vertically by the robot (1), and the detector (5) is fixed to the center of the mounting plate (4). This detector (5) controls the lowermost position of the robot (1) by detecting the height of the uppermost cloth (A) or (B) in the storage section (6) with an optical sensor.

The chucks (31) (31) are made of cloth and are fixed to the L-shaped plates (32) (32), and the cylinders (33) (33) respectively outward (open direction) and inward (close). Direction). In the figure, (33A) is a rod, (41) is a cylinder (33).
Shown respectively are brackets for fixing the to the mounting plate (4).

The pressing pieces (22) (22) are mounted on the mounting plate (4) outside the chucks (31) (31).
The elastic bodies (21) and (21) are fixed to the lower part, and the pen cylinders (23) and (23) fixed on the mounting plate (4) are mounted so that they can be moved up and down. Has been.

FIG. 3 shows the cloth (A). This cloth (A) has a surface (1A) having a raised surface and a wadding (1) made of foam (urethane foam slab material).
B) and a wadding cover (1C) made of nylon half or the like are integrally bonded to each other, and the fabric (B) has the wadding cover (1C) on top.

4 to 6 show a state in which the cloth (A) is supplied from the inside of the storage section (6) onto the jig (71) by the device (D) of the present invention. Figure 2 of the robot (1)
As shown in, moved to the storage section (6). In this state, the detector (5) detects the position of the uppermost cloth (A), and when the robot (1) descends based on this, the elastic bodies (21) of the pressing pieces (22) (22) are moved. ) (21) presses the uppermost cloth (A), and chucks (31) (31)
Joins the fabric (A).

After that, when the left and right chucks (31) and (31) are simultaneously opened by the cylinders (33) and (33), the surface of the cloth (A) bites into the chucks (31) and (31), and the cloth (A). Engage the chucks (31) (31) (FIG. 4). Then, the pressing pieces (22) and (22) are raised by the pen cylinders (23) and (23) as shown by the chain line in FIG. 4 to separate the elastic bodies (21) and (21) from the cloth (A).

Next, when the robot (1) is raised, only the uppermost cloth (A) is chucked (3) as shown in FIG.
