Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention melts a sheet material such as a fiber cloth, a vinyl sheet, and a leather material into a predetermined shape, and at the same time, cuts a part or all of a cut edge by the fusing. The present invention relates to a sheet material fusing device that forms a pattern.

(Prior Art) The inventor of the present invention filed a previous utility model registration application (Japanese Utility Model Application No. 58-17).
No. 8279), "A woven fabric that is attached to a product such as clothing and displays the product name, maker name, size, etc. of which the shape is cut into a polygonal shape such as a rectangular shape, a circular shape, etc. The display plate has zigzags, corrugations, and other edging patterns formed on some or all of the cut edges due to fusing to prevent the cut edges from unraveling. "

The purpose of the device according to the earlier application is to fix the display plate in a flat plate shape to the display portion of the product so that the mounting portion does not become sublime and the user's skin of the product is not damaged. At the same time, the visibility of the display plate is enhanced by forming a fringing pattern on the peripheral edge of the display plate in a part or all of the display plate.

There are various methods for manufacturing the display plate. For example, there is a method of cutting the surface with pinking scissors and then welding the cut end with an electric iron or a heater.

(Problems to be solved by the invention) However, the method of cutting with pinking scissors and welding with an electric gote is not only poor in work efficiency, but also tends to cause unevenness in the thickness of the cut end during welding, and Uniformity is difficult.

Further, a fusing device using a heater has conventionally been capable of performing only a straight line cut, and it is impossible to form a fusing cut end into a zigzag, corrugated pattern or other edging pattern like the display plate according to the above invention. Not only there,
Since a heater is used as a heat source, a portion where the material to be melted becomes hard due to rapid heating appears, which is unsuitable for forming a uniform thickness of the display plate.

In order to solve such a problem, the present inventor uses a "fabric production apparatus for a woven material made of chemical fibers" proposed in the previous application (Japanese Patent Application No. 61-274991) to perform fusing processing. It is also possible to do it.

However, the manufacturing apparatus according to the present invention is "replaceable with an ultrasonic transmitter, and is provided with a cutting edge with a curved line at the center of the circumference, and at both ends of this cutting edge, the cut ends are provided with the same inclination angle to prevent the cut edge from being unraveled. Since it is characterized in that a processing roll having a curved surface is arranged, it is suitable for linearly fusing the sheet material. Fusing a woven cloth such as the display plate into a polygonal shape such as a rectangular shape or a circular shape,
Zigzag, corrugated or other edging pattern is applied to part or all of the cut due to the fusing, button holes are formed in the clothes, or star-shaped or heart-shaped cutouts are applied to the collar or pockets of the clothes. It is unsuitable for so-called cutout processing such as forming point accents.

Further, since it is difficult to form a cutting edge of a predetermined shape on the circumference of such a processing roll, there is a problem that the manufacturing cost of this processing roll increases.

The present invention has been made in view of the above circumstances,
The purpose is to make the fused cut not hard and more uniform in thickness to form a more delicate edging pattern, and also to perform so-called cutting, and further reduce the manufacturing cost of the mold material. An object of the present invention is to provide a sheet material fusing device which can be designed.

(Means for Solving the Problem) The means adopted by the present invention for solving the above-mentioned problems is to "melt the sheet material (T) into a predetermined shape at the same time,
A sheet material fusing device (100) for forming a predetermined pattern on a part or all of a cut (C) by the fusing, comprising a flat mold material (29) having the predetermined shape and the predetermined pattern, A sheet comprising an ultrasonic generator (15) which moves while contacting a sheet material (T) closely arranged on the mold material (29) and melts the sheet material (T) into the predetermined shape. The material is a fusing device (100) ", and the ultrasonic wave generator is provided while the mold material (29) and the sheet material (T) closely arranged thereto are movably formed. 15) may be fixed, and the mold material (29) and the sheet material may be further fixed.

(Object of the Invention) Therefore, according to the present invention, the sheet material (T) is closely arranged on the flat mold material (29) having the predetermined shape and the predetermined pattern, and the sheet material (T) is moved while contacting the sheet material (T). By the ultrasonic generator (15), the sheet material (T) is melted and cut into a predetermined shape, and at the same time, a predetermined pattern is formed at the cut (C) so as to prevent the cut (C) from unraveling.

Further, by forming the mold member (29) and the sheet member (T) so as to be movable and fixing the ultrasonic wave generator (15), the power supply to the ultrasonic wave generator (15) is hindered. And the ultrasonic wave generator (15), the mold member (29), the sheet member (T) and the ultrasonic wave generator (15) are movable so that the operation time for fusing can be increased. It acts to shorten it.
