Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Object of the Invention) The present invention relates to an automatic heat cutting device for a piercing sewing machine.

(Field of Use of the Invention) In the field of stabs, especially atupliqués, it is used for cutting out appliqué materials (various appliqués before stabs).

(Prior Art) Conventionally, the cutting of the appliqué material has been performed by punching the appliqué cloth using a press die, or by hand cutting with a heat cutter using a pattern paper.

(Problems to be solved by the invention) The press die punching with the press die is mainly performed by a specialized manufacturer, but the production cost of the die is high, and it is not profitable unless it is mass-produced in terms of work. . In recent years, individuality has also increased to the taste of appliqué, and a small amount for this request uses a handheld heat cutter,
Currently, it is cut out by hand. In the case of manual work, the work time and various expenses associated therewith are increased, and the cutting accuracy of the cotton pens is artificially caused, resulting in a lack of accuracy. An object of the present invention is to solve the above-mentioned conventional problems, to obtain an automatic heat cutter device which is easy to operate and has a high cutting accuracy.

[Structure of Invention]

(Means for Solving the Problems) A first technical solution taken in the present invention to solve the above-mentioned problems is a sewing machine in which a heat cutter is combined with an embroidery sewing machine to automatically operate and cut the cloth. The raising and lowering of the heat cutter is performed by activating the driving means by a signal programmed so that the cutter contacts the cloth surface immediately before the cloth moves and is separated from the cloth surface immediately after the cloth stops moving. It is an automatic heat cutter device for embroidery sewing machines.

A second solving means is a sewing machine which automatically operates and cuts a cloth by combining a heat cutter with a embroidery sewing machine, and raises and lowers the heat cutter so that the cutter comes into contact with the cloth surface immediately before the cloth is moved. Immediately after the movement is stopped, the driving means is actuated by a signal programmed to separate from the cloth surface, and the heat cutter is operated to damp the drop force when descending from the standby position toward the cloth surface. The damper means is an automatic cutter device for an embroidery sewing machine, which is provided in cooperation with the operation of the drive means.

(Operation) Hereinafter, the operation of the present invention will be described with reference to FIGS.

A cloth 1 for a cotton pen is fixed to a plate 2 by a magnet 3, and the plate 2 is a piercing frame driving body 4 of a piercing sewing machine (moves according to data in the arrow (XY) direction).
It is fixed by an appropriate means (for example, the interposition of a magnet) and moves in the shape of a hat pen. The heat cutter 5 is tightly held by the hinge member 6 (hereinafter, the combination of the both 5 and 6 is referred to as a heat cutter unit).

The heat cutter unit oscillates around a pin 8 on a mounting plate 7 provided on the machine frame as a fulcrum in response to an operation of a solenoid 9 according to a signal from a program (not shown). Reference numeral 10 is a damper for preventing the heat cutter 5 from colliding with the cloth 1 on the plate 2 when the heat cutter unit descends (this damper is provided with an elastic cushion material,
Alternatively, means for generating air resistance or the like, and other appropriate methods may be considered).

The heat cutter 5 secures a temperature sufficient for cutting (fusing) the cloth by heat, descends onto the cloth 1, and the cloth 1 is moved by the plate 2 to be cut. So the first
In the figure, a mode in which the letter A is cut out is illustrated. Next, the operation of cutting the cotton pens will be described. Standby position (shown by the solid line in Figure 1)
In response to the program signal, the solenoid 9 is actuated in the direction of the arrow with respect to the heat cutter unit of No. 1, and the heat cut unit is lowered by the resistance of the damper 10 onto the cloth 1 as shown by the dotted line. Then, the heat cutter 5 comes into contact with the cloth surface, and the cloth 1 automatically starts to move after tsec (several seconds) as shown in the diagram of FIG. (If the heat cutter comes into contact with the cloth from an early stage and stops for a long time, the cloth will melt significantly,
What's wrong with the quality of watsupen).

Next, at the end of cloth cutting, that is, after tsec when the movement of cloth 1 is stopped, the solenoid 9 is activated again, and the heat cutter unit is automatically returned to the original standby position.

〔The invention's effect〕

After the cloth is set on the plate, a predetermined program operation is performed when the device is turned on, and the cloth is automatically moved from raising and lowering of the heat cutter unit, and the cloth does not melt too much. For example, in the letter A shown in Fig. 3, the heat cutter unit is raised and lowered by 2 for each, including the cutout of the part 11.
The cloth can be cut in a timely manner, and the cloth can be heat-cut satisfactorily without any effort and without failure.
