[0002]

2. Description of the Related Art As shown in FIG. 3, a trim cover (B) used for an automobile seat has a skin (b ₃ ) which becomes the surface of the seat and a wadding (b) made of foam (urethane foam slab material). ₂ ) and a wadding cover (b ₁ ) such as a non-woven fabric which is integrally fixed to the back surface of the wadding (b ₂ ), and a bag-shaped hanging member is provided on the back surface side of the trim cover (B). It is sewn together.

The hanging member is a bag-shaped trim cover (A) which is made of a tape-like cloth, is folded in the width direction, and both ends thereof are integrally sewn to the trim cover (B). It is fixed to. In addition, a core wire is inserted into the suspension member, and the core wire is inserted into a concave groove provided on the surface of a molded foam pad (not shown) covered with the trim cover (B) to fix the inside of the pad. By binding the trim cover (B) to the member, the trim cover (B) can be covered along the uneven pad surface without any gap.

The sewn product A is cut into a predetermined length in advance, folded in the width direction, and the sewn product B which is a trim cover (B) is placed on the table board of the automatic sewing machine. The jigs are stacked and the jigs are sent and the sewing machine is sewn.

[0005]

Therefore, the work to be sewn A
Had to be cut into a predetermined length and fixed to a jig, which was a bad operation. Therefore, an object of the present invention is to automatically supply the sewn product A cut into a predetermined length to the sewn product B.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, a sewing machine automatic feed device for sewing machines according to the present invention is installed below a sewing machine table, and a sewing machine is provided with a sewing machine to feed a sewing machine A. A feeding mechanism that clamps and feeds,
The cutting mechanism is provided between the feeding mechanism and the sewing machine needle, and the cutter is actuated by a timer to cut the workpiece A. The feeding mechanism includes a feeding roller rotated by a motor and the feeding roller. The present invention is characterized in that it comprises a caster for joining the material to be sewn A to the roller.

[0007]

[Function] A tape-shaped sewing object A wound in a roll shape
Is supplied to the sewing machine needle on the lower side of the product B to be sewn by the feeding mechanism for a fixed time set by the timer. Then, after a certain period of time, the sandwiching state of the product A to be sewn by the feed mechanism is released, and the supply by the feed mechanism is stopped.
Is fed out, and after a predetermined time, the cutting mechanism is operated to cut the product to be sewn A and sew it to the product to be sewn B integrally.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the figure, (A) is a multi-needle sewing machine main body, (T) is a sewing machine table, (A) is a sewn product A, (B) is a sewn product B,
(C) shows a feeding mechanism and (D) shows a cutting mechanism. The sewing machine main body (a) is an automatic sewing machine having a large number of sewing needles (11) ... In a direction orthogonal to the feed direction of the articles A, B (A) and (B). In the figure, (12) is a presser foot,
(13) shows a needle plate having a feed dog. The material to be sewn B (B) is placed on the sewing machine table (T) and fed into the sewing machine needle (11) by the movement of a jig (not shown).

In the vicinity of the sewing machine needle (11) in the above sewing machine table (T), the supply port (1) for the sewing material A (A) is provided.
4) is opened, an introducing pipe (8) is fixedly provided between the supply port (14) and the needle plate (13), and the jig moves on the introducing pipe (8).

As shown in FIG. 3, the sewing object A (A) is
A bag-shaped hanging member that is integrally sewn on the back surface of a trim cover, which is a material to be sewn B (B) used for an automobile seat, and a long object (tape) wound in a roll shape in a width direction 2 It is folded and sewn at its both ends to the sewing target B (B) with the main body of the multi-needle sewing machine to form a bag. (A) in the figure
(A) shows the seam which sewn the to-be-sewn material A (A).
The sewn object B (B) is a skin (b ₃ ) forming the surface of the seat, and a multi-needle sewing machine main body (a) together with the wadding cover (b ₁ ) on the back side of the skin (b ₃ ). ), And a wadding (b ₂ ) made of a urethane foam slab material that is sewn together with the slab material.

The feed mechanism (C) is mounted below the sewing machine table (T) and feeds the sewing target material A (A) wound in a roll by a feed roller (1) and casters (2). It is a structure that is sandwiched by and supplied to the sewing machine needle. The feed roller (1) is rotated by driving a motor (M) by a timer for a certain period of time, and the caster (2) is electrically connected to the timer so that the feed roller (1) rotates when the feed roller (1) rotates. It is configured to move in the (1) direction by a cylinder (21) and join the work A (A) to the feed roller (1).

The cutting mechanism (D) is a feeding mechanism (C).
It is composed of a cutter (3) arranged above and a cut receiving stand (4) made of synthetic resin. This cutter (3)
The cylinder (31) works to cut the cutter (3) when the sewing machine A (A) moves by a certain size by the presser foot (12) of the sewing machine body (A) and the feed dog, and the cutter pedestal (4) is cut.
By pressing in the direction, the sewing object A (A) is cut.

The above feeding mechanism (C) and cutting mechanism (D)
Is disposed in the guide portions (5) (7) provided between the wound body (A ″) of the sewn material A (A) and the supply port (14) provided in the sewing machine table (T). .

The winding body (A ″) is formed by winding a tape-shaped cloth (A ′), and the cloth (A ′) is wound inside the folding binder (6) on a turntable having a core body (61). As it passes, it is folded in two in the width direction and fed to the guide portion (7) consisting of a U-shaped groove having a tubular body at the tip, and the feeding mechanism (C) is provided in this guide portion (7). The cutting mechanism (D) is provided at the end of the guide part (7), and a guide part composed of a rectangular guide tube is provided between the cutting mechanism (D) and the supply port (14). (5) is provided,
The material to be sewn A (A) that has passed through the guide portion (5) is inserted into the introduction tube (8).

The folding binder (6) described above has a gradually narrowing V in the feeding direction of the fabric (A ').
It is a character-shaped tubular body, and when the cloth (A ') is fed, the tape body is folded into two tape bodies and fed to the guide portion (7).

Next, the operation of this apparatus will be described. First, the operation time of the feed roller (1) and the caster (2) which form the feed mechanism (C) is set by the timer. Therefore, within this operating time, the material to be sewn A (A) is held between the feed roller (1) and the casters (2) and fed to the wire. At this time, the sewing target B (B) placed on the jig is placed on the tip of the sewing target A (A) as shown in FIG. It should be noted that in the jig, the sewing target A (A) is the sewing target B
A slit is provided so that (B) can be sewn. After the work A (A) is sent to the needle plate, the caster (2) separates the work A (A) by the cylinder (21) and the rotation of the feed roller (1) is stopped.

Next, when the sewing machine main body (a) is driven, sewing is started, and the presser foot (12) of the sewing machine main body (a),
The material to be sewn A (A) is sewn together with the material to be sewn B (B) by the sewing machine needle (11) by the feed dog (13) and is fed. After a certain time set by the timer, the cutting mechanism (D) is The work to be sewn A (A) is cut. Then, the cut sewing object A (A) is integrally sewn to the sewing object B (B) as shown in FIG. 3 to form a bag-shaped suspending member.

After cutting, the cutter (3) of the cutting mechanism (D) is retracted by the cylinder (31). After that, the feed mechanism (C) is activated by the timer,
The material to be sewn A (A) is fed to the needle plate as described above and sewn as described above.

[0019]

According to the present invention, the material to be sewn A is automatically supplied to the sewing machine needle by the feed mechanism and cut into a certain size by the cutting mechanism. Therefore, it is not necessary to cut the sewn product A into a predetermined size and fix it to the jig unlike the conventional product, and the workability is greatly improved.
