製装置である。2. Description of the Related Art As a device for sewing a hole pattern on a fabric,
Conventionally, for example, there is one described in Japanese Patent Application Laid-Open No. 8-158235. This conventional technique is a rotary knife that forms a hole in a base cloth in a rotating knife mounting base that descends while the needle bar of the automatic embroidery sewing machine is stopped and operable while the needle bar is stopped. A needle guide for guiding the sewing machine needle at the lower end of the needle bar is provided at the lower end of the elevating bar provided adjacent to the needle bar, and the needle bar and the elevating bar are formed in the base fabric by the rotary knife. This is a hole-shaped pattern sewing apparatus provided with interlocking means for interlocking the lowering rod to the lower limit and guiding the sewing machine needle only when a stitch is formed in the sewing machine.

る。That is, in this conventional example, during operation of the automatic embroidery sewing machine, the needle bar stops at the upper limit in response to a specific signal, and at the same time, the rotating knife mounting base is lowered to rotate the lower-pointed rotating knife to the embroidery bar. After "piercing" the pierced base cloth, the base cloth is pushed and spread to form a fuzzy small hole, and then the rotating knife mount is raised.
Next, the embroidery frame moves, the hole just formed moves immediately below the needle bar and stops, and then the needle guide descends at a slightly earlier timing than the sewing machine needle to hold the hole at a predetermined size.

When the sewing needle goes up and the needle guide goes up, the embroidery frame moves and the holeless portion of the base fabric comes to just below the needle bar and stops, and then the sewing machine needle moves up and down to stitch the holeless portion. create.

When the sewing needle and needle guide rise, the hoop moves. By forming a stitch around the hole provided in the base cloth by repeating the above-described operation, the area around the hole is so-called "sewn" to "snap" the base cloth.

う本質的な問題点が有る。The drilling rotary cone referred to as a rotary knife in the above-mentioned prior art is a rotary cone as described in the above-mentioned prior art publication "0018" which is the only embodiment of this prior art. The lower end of the scalpel is pointed in the shape of a cone or a pyramid, and tapered blades are provided along these pyramids in all directions vertically like a glass pen before a long time ago,
"These blades have no blades so that they do not cut the cloth." In other words, in order to make a hole in the cloth with such a pointed rotary knife, as described above, while rotating the conical rotary knife, piercing the base cloth with no rest on the lower surface using the tension By forcibly spreading the base fabric with the rotating blades, a hole is made in the base fabric.
Therefore, since this hole will be drilled by penetrating the lower pointed cone into the base cloth, it is necessary to tighten the base cloth to the hoop, which is an essential problem that the hoop cannot be implemented without the hoop. There is.

It is necessary to do "scratching" around the hole and to make the outline of the hole clear, which is troublesome and troublesome, and it is not possible to make beautiful holes in leather, plastic films and sheets. There are also problems.

In addition to the third problem that swelling in the form of a crater prevents flat “Kagari sewing”, it is not possible to drill a large hole with a diameter of 5 mm or more in the base cloth with a lower-pointed rotating cone called a scalpel. Many essential and
There are serious problems.

The sewing machine head is provided with at least one needle bar for performing embroidery stitching. The two needle bars of the sewing machine head each have a needle bar tip formed on a cutter blade, and one of the needle bars has a The other one should be in the direction perpendicular to the weft of the woven fabric so as to be in the direction perpendicular to the warp, and firstly, stitch stitching of the desired pattern to the appropriate portion of the woven fabric, and then The warped and weft threads are sequentially cut by the up and down operation of the cutter blade on the inner side of the stitched stitch to form a stitch stitching pattern shape, and then the overlocking of the peripheral portion formed by another needle bar is performed. This is a method for creating a pattern in sewing embroidery.

大な問題点が有る。In this conventional example, two rectangular cutter blades each having a flat blade-like inclined surface are provided at the lower part of two needle bars for drilling a square hole or a circular hole at a drilled portion.
This is a method of perforating the fabric by separating and cutting the diameter yarn and the weft yarn of the fabric using a single cutter blade. Therefore,
Even when drilling a small acupuncture hole with a diameter of about 5 mm in the fabric, it is necessary to raise and lower the orthogonal two cutter blades about 20 times each for a total of about 40 times. In addition, the outline of the hole is unclear and a beautiful hole cannot be drilled.
There is an essential and significant problem of not being able to drill holes in the fabric.

As described above, the fabric, leather, and other sheet-like base fabrics 2 to be perforated are placed directly on the plate material 1a or through a well-known automatic frame in an automatic embroidery machine.
Next, the two needle bars 7 in the head 6 are moved by the needle replacement rod 14 for positioning the sewing machine head 6 by moving it sideways.
Of these, only the lifting piece 15 of the needle bar 7 provided with the rotary punch 3 is moved up and down at the top dead center of the needle bar 7 as shown by the solid line in FIG.
While rotating the punch 3 at a high speed of about 200 to 300 times per second by supplying air from the pipe P into the drilling tool 3A.

る。At the time of this drilling, the needle bar 7 having the sewing machine needle 10 is immovable, and the base cloth 2 is attached to the rough surface with a rough upper surface of the base cloth receiving seat 1 or the friction surface. As a result, it was possible to prevent lateral displacement of the base cloth, and it was possible to make a beautiful circular hole 5 in the base cloth 2 instantaneously. After drilling, the rotary shaft 18 is stopped at the top dead center of the rotary punch 3 as shown by the solid line in FIG. 1 and the punch 3 is kept up, so that the linear bundle of the base cloth receiving seat 1 is made of the material. The original dense storage state shown in FIG. 1 is restored with the inherent elasticity.

By pulling the needle changing rod 14 in the direction indicated by the arrow in FIG. 2 and moving the sewing machine head 6 to the right by the needle bar interval, this time, the elevating piece 1 of the needle bar 7 having
By rotating the rotating shaft 18 after the concave / convex engagement of the shaft 5, the lifting arm 21 and the rotating arm 22 including the cam plate 19, the ring piece 23, the lifting cylinder 16, and the lifting piece 15 are sequentially passed. Only the needle bar with the sewing needle 10 moves up and down,
The edge of the circular hole 5 of the base cloth 2 could be sewn with the sewing needle 10 by the well-known sew-around needle operation.
