Description

  The present invention relates to a transfer device for a sequin supply unit, and more specifically, a sequin connection body mounted on a side surface of a sewing head and wound on a reel is unwound, and the sequin connection body is cut and a needle and an embroidery are cut. In a sequin sewing device that uses a thread to sew onto a workpiece, the cutting position of the sequin connection body can be easily changed by changing the fixed position of the sequin supply device according to the size of the sequin connection body. The present invention relates to a transfer device of a sequin supply unit.

  Generally, sequin or sequin is a film of a synthetic resin material having a certain width, and is formed in a circular shape with a hole of a predetermined size formed in the center. The sequin coupling body used for the sewing work is a form in which a large number of sequins are coupled in a row, and is sewn one by one using a sequin sewing device and fixed on the workpiece.

  As a conventional technique of such a sequin sewing apparatus, one disclosed in Patent Document 1 (title of invention: sequin supply apparatus) is known.

  As shown in FIGS. 1 and 2, the conventional sequin sewing device 10 is roughly divided into a base block 30 that is attached to a side surface of a sewing machine head 60 through predetermined joining means and a number of link structures, A reel holder 20 that is rotatably attached to the upper end portion of the base block 30 and to which a reel that is stored by winding a sequin coupling body is fixed, and a lower end portion of the base block 30 that is attached to the reel block 20 and is detached from the reel. The sequin connection device 40 is configured to transmit the connected sequins at a predetermined pitch using a number of mechanisms.

  The sequin sewing apparatus 10 is mounted so as to be reciprocally movable up and down with respect to the sewing machine head 60 using a large number of link structures and cylinders, so that it does not interfere with normal embroidery work when the sequin sewing work is not performed. In addition, when the sequin sewing device 10 is retracted upward and the sequin sewing operation is performed, the sequin sewing device 10 is moved downward to perform the sewing operation.

  On the other hand, as shown in FIG. 2, the sequin supply unit 40 installed at the lower end of the base block 30 includes a support block 42 attached to the lower end of the base block 30 using a predetermined coupling means, and the support block 42. It comprises a support plate 43 formed horizontally for placing sequins on the lower end of the block 42, and a bracket 44 mounted on one side of the support block 42 using a predetermined joining means. .

  The support plate 43 is formed in a rectangular plate shape, and an elongated slot hole is formed in the center with a predetermined width.

  Further, the bracket 44 is formed in a rectangular plate shape having a bent portion having the same inclination as the one side inclined surface of the support block 42, and a sequin pushing plate is used at the lower end portions of the front and rear surfaces using predetermined coupling means. A spring 45 and a guide portion 46 are respectively attached.

  However, in the sequin sewing device, the cutting position of the sequin coupling body must be changed depending on the size of the sequin coupling body sewn on the sewing product. For this reason, in an existing sequin sewing device, the sequin supply device on which the sequin cutting knife is attached must be moved in order to change the cutting position of the sequin coupling body. At this time, the operator releases the fixing screw fixing the support block to the base block with a screwdriver, moves the support block by a certain distance according to the size of the sequin, and then fixes the base block again to the base block with the fixing screw. .

  However, such a moving operation takes a lot of time, and it is not easy to move an accurate distance depending on the size of the sequins, causing a problem that sequin sewing failures frequently occur.

Korean Registered Patent No. 10-0597201

  Accordingly, the present invention has been made to solve the above-described problems of the prior art, and the object of the present invention is to cut the sequin coupling body according to the size of the sequin coupling body sewn on the sewing product. It is an object of the present invention to provide a transfer device for a sequin supply unit whose position can be easily changed.

  Other objects of the present invention will be apparent to those skilled in the art from the following detailed description of the invention.
