Description

DETAILED DESCRIPTION OF THE INVENTION This invention Fi is an electronic pattern sewing machine that sews or embroiders a pattern on cloth or leather by moving the cloth or leather holding member in the X-Y axis according to data stored in the memory. A laser beam emitting nozzle is installed near the needle,
Equipped with a laser cutting device that uses a laser beam to cut, tack, or create a baked pattern on the surface of the sewing material at the same time as sewing, or to cut cloth or leather continuously using a laser beam after sewing. This invention relates to an electronic pattern sewing machine.

Generally, in the sewing process, cloth or leather is first cut into shapes to make it easier to sew patterns.

The process involved basting the material, sewing patterns, etc. onto it, and finally creating a baked pattern on the surface of the leather.

In this sewing process, the cloth or leather is first cut into small pieces in the desired shape, and then the pattern is sewn on.
It is difficult to hold the cloth when sewing the pattern, especially when creating a pattern on the surface of the leather that needs to be done in the last step, because this step cannot be carried out first. was considered a problem.

This invention was made in view of these points.
Pattern stitching is carried out while the leather remains large, and while the cloth and leather are being held for this pattern sewing, the cloth and leather can be cut into the desired shape at the same time as and following the pattern sewing. The present invention provides an electronic pattern sewing machine with a laser cutting device that is easy to hold in each step of leather cutting.

An embodiment of the present invention will be described in detail below with reference to FIG.

In Figure 1, (1) is the sewing machine body, (2) is the sewing machine table, (3) is the throat plate of this sewing machine table, and (4) is the sewing machine table.
11d Sewing machine head, (5) is a needle. (6) is a holding member made of cloth or leather provided at a location corresponding to the throat plate (3) and needle (5) on the top I of the table (2), and the cloth or leather is held between a pair of upper and lower frames. do. (7111t This is a drive unit that moves this holding member in the X-Y axis direction.

(8) is a nine arm attached to straddle the table (2), (9) is attached to this arm and is a laser beam emitting tube located close to the needle (5) K; Main body (
1), the laser beam from this transmitter passes through the supply pipe αυ to the laser emitting tube (9).
supplied to

Figure 2 schematically shows the control circuit configuration.

a3 is the power supply, C13 is the central control circuit, a4a'1a
eti, a needle drive motor (171), a control circuit for the laser transmitter ill, and a holding member drive unit (7), (8
) is a memory for storing sewing pattern data and cutting shape data.

In addition, Ql is a needle position detection device, and its detection part is located on the head (
4) is attached to the upper shaft.

In the above configuration, the cloth or leather is held between the upper and lower frames of the holding member (6). In this state, the control circuit 1eK extracts the sewing pattern data stored in the memo IJ-08 and supplies it to the drive unit (7) to move the holding member (6) in the X-Y axis direction, and at the same time drive the needle (5). By driving the motor fin, the desired pattern is sewn onto the cloth or leather. Of course, at this time, the position of the needle (5) is detected by the position detection device α9, and this is input to the central control circuit (13), so that the holding member (6) is at the position of the needle (5).
The object is moved in the X-Y axis direction. In other words, when the needle (5) is stuck in cloth or skin, #i holding member (6
) is stopped, and when the needle (5) reaches a position above the cloth or leather, it moves in the X-Y axis direction.

Next, in response to a command from the central control circuit 0, the control circuit tJe takes out cutting shape data from the memory Ole and supplies it to the drive section (7). As a result, the holding member (6) holding the cloth or leather moves in the X-Y axis directions so as to draw the cut shape. In accordance with this movement, the laser transmitter Ql is activated to emit laser light from the laser emitting nozzle (9). As a result, the cloth or leather is cut into a predetermined shape.

Here, to make the cutting occur at the same time as pattern sewing.

The laser transmitter members are activated simultaneously in accordance with the needle drive motor Qη, and the laser emitting nozzle (9) is set in the X-Y axis direction for pattern sewing of the holding member (6) so that it has the cut shape of T. This is done by moving the robot and making a relative swing of the head. (The mechanism and control circuit for swinging the laser emitting nozzle are omitted in the drawing.) In addition, if you do not cut the leather using a laser beam, but instead print a pattern on its surface, the laser beam Needless to say, this can be done by adjusting the strength of.

Therefore, since the electronic pattern sewing machine with a laser cutting device according to the present invention has the above-mentioned configuration,
It has the advantage that sewing and cutting can be done at the same time and in the same setup, and that attaching the cloth or leather to the holding member can be done easily.
