Description

[Detailed Description of the Invention] [Industrial Application] The present invention relates to an automatic hole-making device, more specifically, a buttonhole machine that moves men's or women's clothing relative to a sewing machine and attaches buttonholes to the cloth. The present invention relates to an automatic drilling device that automatically threads holes.

[Prior Art] Such an automatic hole punching device, also called an indexer, automatically and sequentially punches a plurality of buttonholes attached to men's or women's clothing. ．． In this case, after positioning the cloth by applying it to the gauge of the indexer, sewing is performed while feeding the cloth sequentially to multiple buttonholes, and parameters such as the number of buttonholes and the spacing between buttonholes are specified. The sewing machine is configured to be able to automatically perform hole sewing on cloth for men's or women's clothing.

[Problems to be Solved by the Invention] When sewing holes manually using such an indexer, the positioning of the cloth is based on men's clothing. The upper end of the cloth is placed against the gauge, and the stitching is carried out by feeding the cloth in one direction from the first buttonhole to the last buttonhole in one direction toward the hem end.

The buttonhole arrangement for women's clothing is reversed from that for men's clothing, so when sewing women's clothing, it is necessary to sew multiple buttonholes in the same direction as the cloth feeding direction for men's clothing. After placing the edge of the hem against the reference gauge and setting the garment, the button is stitched in the opposite direction from the last button, and finally the first buttonhole is stitched. In this method, for men's clothing, the first hole is positioned from the top edge of the fabric, so even if there is an error in buttonhole spacing, etc., the difference between the last hole position and the hem edge will be determined by the cumulative error. It is not that big of a problem if an error occurs in the hem, but in the case of women's clothing, on the other hand, the last hole is stitched using the hem edge as a reference, so if there is an error in the initial setting or if multiple holes are stitched, Errors accumulated in the first hole are accumulated in the first hole, and in some cases, there is a problem in that a considerable error occurs in the distance between the upper end of the cloth and the first hole. Therefore, when sewing fabrics such as dress shirts, etc., the distance between the top edge of the fabric and the first hole is extremely important for dimensional accuracy. Errors were a big problem.

Therefore, the present invention was made to solve these problems, and regardless of whether it is a men's item or a women's item,
To provide an automatic buttonhole sewing device which can sequentially sew from a first buttonhole to a final buttonhole and can automatically perform sewing with high precision.

[Means for Solving the Problems] In order to solve the above problems, the present invention has a method of moving men's clothing or women's clothing relative to a sewing machine and automatically sewing buttonholes in sequence. In an automatic sewing machine, a means for selecting a men's or women's sewing mode is provided, and when the men's clothing sewing mode is selected, the men's clothing is moved in a predetermined direction relative to the sewing machine, and the sewing machine sequentially starts from the first buttonhole. means for sewing a hole; and when a women's clothing sewing mode is selected, moving the women's clothing along the predetermined direction to a position corresponding to a first buttonhole of a men's clothing, and sewing the first buttonhole. After the buttonholes are finished, the fabric is moved in the opposite direction and the remaining buttonholes are stitched.

[Function] With this configuration, when sewing men's clothing, the upper end of the cloth is placed on the gauge as in the past, and the holes are threaded sequentially from the first hole toward the last hole at predetermined hole intervals. The holes are drilled automatically in sequence. On the other hand, for women's clothing, after placing the cloth in a predetermined position according to the women's clothing gauge, move the cloth to the position corresponding to the first buttonhole of men's clothing, and
After finishing sewing the buttonholes, the cloth is moved in the opposite direction and sewing is performed while automatically feeding the cloth sequentially until the last buttonhole.

[Example] The details of the present invention will be described below based on the example shown in the drawings.

FIG. 1 shows the overall configuration of an automatic hole punching device according to the present invention. be done. A conveyor 3 is arranged to be able to slide freely in the direction indicated by X with respect to the sewing machine 1. This carrier 3 has a plurality of clamps 3a, and is configured to be able to move up and down in the up and down direction Y by a device not shown. A brisset table 4 is arranged in front of the carrier 3,
On this brisset table 4, a men's cloth 5 or a women's cloth 6 to be pierced is placed in position with respect to a men's cloth gauge 7 and a women's cloth gauge 8, respectively.

With this brisett table, two pieces of body can be set on one indexer, and the operator can take a long time from setting the fabric to setting the next fabric.
It becomes possible to take extra time for holding the stand (stand) and replacing the bobbin.

This brisset table 4 is provided with a clamp 4a, which fixes the cloth placed on the brisset table. This brisset table 4 is configured to be able to move forward and backward in eight directions. Furthermore, an operation panel 9 is provided, and on this operation panel there is a selection button 9a or a buttonhole button for selecting whether the fabric to be stitched is men's or women's and selecting the sewing mode accordingly. Keys 9b and the like are arranged for setting parameters such as the number of buttonholes and the interval between buttonholes. Further, a start switch 10 is provided on the front of the device, and by actuating the start switch 10, sewing by the sewing machine can be started.

Next, the operation of the device configured in this way will be explained.

First, prior to starting the operation of the device, parameters such as the number of buttonholes to be attached and buttonhole spacing are set. Next, as shown in step S1 in FIG. 2, the user operates the button 9a for selecting whether the cloth to be sewn from these is women's clothing or men's clothing. If it is determined in step S2 that it is a gentleman's item, step S
At step 3, the conventional men's wear sequence begins. In this sequence, as shown in detail in FIG.
The needle drop point 1a of the sewing machine 1 is positioned such that the sewing start point of the first hole 5a coincides with the needle drop point 1a of the sewing machine 1. After being preset in this manner, the presetting table 4 moves forward in the direction A, and the men's clothing 5 is transferred from the presetting table 4 to the conveyor 3. Thereafter, the sewing machine 1 threads the hole 5a of 's1, and when this is completed, the conveyor 3 moves in the direction M (in Fig. 3) and threads the second hole in the same way. ．． Then the last hole 5 according to the set parameters
When all the buttonholes have been stitched by sewing the holes in b, the conveyor 3 returns to its original position, releases the cloth, and deposits it on the stacker below. On the other hand, if it is determined in step S2 that the mode is women's clothing mode, it is determined in steps $4 and S5 whether the start button has been pressed or the cloth has been set, and the brisset table 4 moves forward in step S6. In this case, the women's cloth 6 is brisseted as shown in FIG. 3(B). That is, the upper end 6a of the women's clothing 6 is positioned relative to the women's clothing gauge 8 on the left side of the device. In this case, the gauge 8 is placed at a distance 11tL (for example, 590 mm) from the needle drop point 1a to the first hole, plus a distance aiA from the upper end of the body to the first hole. Ru. Thereafter, in step S7, the women's cloth 6 is transferred from the brisset table 4 to the conveyor 8, and then moved in the M direction by a predetermined distance 111L in step S8. As a result, the first
The left end of the hole 6a coincides with the needle drop point 1a, and the first hole is stitched under the same conditions as men's clothing. After that, the conveyor is moved in the direction opposite to the M direction, and the holes are stitched starting from the second hole following the first hole, sequentially toward the hem end 6d, and then stitched to the last hole 6b (step S9, S10). When the last hole 6b is stitched, the conveyor 3 returns to its original position and the fabric is stacked downward in the same way as men's clothing, completing the series of sewing. The above-mentioned sequence is realized by a built-in microcomputer, etc. In the embodiment shown above, the women's cloth is set on the brisset table 4 and then moved to a predetermined position by the conveyor, but in the example shown in FIG. In this case, according to Figure 1, it is considerably to the right of the men's clothing.
For example, it is set by hand and preset so that the first hole 6a initially coincides with the needle drop point a. In the case of this embodiment, since the moving distance L in FIG. 3 is carried out by hand from the beginning, by moving the cloth 6 in the direction opposite to M, it becomes possible to carry out the same hole stitching. [Effects of the Invention] As is clear from the above description, according to the present invention, it is possible to sew both women's clothing and men's clothing from the first hole with one device, When darning,
It becomes possible to almost eliminate errors in the important dimensions of the upper edge of the cloth and the first buttonhole.
