sequins

371, 372, and 373 supplied in a band form between the needle and the fabric fabric.

The guide cam device 340 is driven by the second rotating shaft, and guides the

sequins

371, 372, and 373 supplied in the form of a plurality of bands to selectively engage each of the plurality of

sequin gears

351, 352, and 353. Or guide them apart. At this time, the selected sequin band 371 is engaged with the corresponding sequin gear 351 and is supplied between the needle and the fabric fabric according to the rotation of the

sequin gears

351, 352, and 353, but the

sequin bands

372 and 373 are not selected. Is spaced apart from the

corresponding sequin gears

352 and 353 and remains stopped even when all of the

sequin gears

351, 352 and 353 rotate.

The plurality of

sequin gears

351, 352, and 353 and the guide cam device 340 are installed on the main plate 360. The main plate 360 reciprocates from side to side to adjust the position so that the selected sequin band 371 is supplied between the needle and the far end.

The

sequin bands

371, 372, and 373 are supplied between the needle and the fabric via the

sequin gears

351, 352, and 353 without departing outwardly by the

sequin guides

310, 320, and 330, respectively. The

sequin guides

310, 320, 330 are in contact with the guide cam device 340, and the guide cam device 340 has grooves formed in a portion of the circumference in contact with each of the

sequin guides

310, 320, 330. . The grooves formed at this time are alternately formed with respect to the

sequin guides

310, 320, and 330.

When the first sequin band 371 is selected, the first sequin guide 310 contacts the circumferential groove of the guide cam device 340 so that the first sequin band 371 engages with the first sequin gear 351. You are guided to Accordingly, as the

sequin gears

351, 352, and 353 rotate, the first sequin band 371 is guided between the distal end and the needle.

In the state where the first sequin band 371 is selected, the

remaining sequin guides

320 and 330 contact the convex portions on the circumference of the guide cam device. In this case, each of the second and

third sequin bands

372 and 373 is spaced apart from the second and

third sequin gears

352 and 353 by a predetermined distance S2 and S3 and the

sequin gears

351, 352 and 353. Even if this rotation is performed, the second and

third sequin bands

372 and 373 remain stopped.

In the above manner, the multi-sequined guide device may select one of the plurality of sequin bands and guide it between the needle and the distal end.

On the other hand, the

sequins

372 and 373 which are not sealed (not guided between the fabric fabric and the needle) are guided so as not to be separated out by the

sequin guides

320 and 330. The configuration of the

sequin guides

310, 320, 330 will be described based on the first sequin guide 310.

The first sequin guide 310 includes a spring 311. The spring 311 is positioned in the first sequin guide 310 while being forced in the direction in which the spring 311 is pressed. The inner guide 312 engages with the spring 311 to push the first sequin band 371 outward. Since the spring 311 is forced in the pressing direction, the spring 311 and the inner guide 312 push the first sequin band 371 outward by the restoring force.

Although the spring 311 is provided in the above embodiment, any elastic element having elasticity and restoring force may be used according to another embodiment of the present invention.

The first sequin guide 310 further includes an outer guide 313 that supports the first sequin band 371 from the outside. The outer guide 313 prevents the first sequin band 371 from escaping from the first sequin guide 310. When a force is not applied to the first sequin band 371 from the outside, the first sequin band 371 is formed by the frictional force between the inner guide 312 and the outer guide 313. Is fixed between). As a result, when the first sequin band 371 is not selected, the position of the first sequin band 371 is fixed, and when the first sequin band 371 is selected again, the first sequin band 371 is correctly formed. It can be combined with the cog wheel of the one sequin gear 351.

When a force is applied from the outside to the first sequin band 371, the first sequin band 371 is selected. When the first sequin band 371 is selected, since the first sequin band 371 and the first sequin gear 351 are coupled, the first sequin band 371 is woven by the rotation of the first sequin gear 351. Pulled in the distal direction. In this case, since the force applied to the first sequin band 371 by the first sequin gear 351 is greater than the friction force between the inner guide 312 and the outer guide 313, the first sequin band 371 is made of a fabric fabric. Guided in the direction.

Meanwhile, one side of the first sequin guide 310 may be pivoted in combination with the hinge shaft 361 installed on the main plate 360. The other side of the first sequin guide 310 is connected by the support 315 and the spring 314 installed on the main plate 360. The spring 314 pulls the first sequin guide 310 so that the first sequin guide 310 maintains contact with the first sequin gear 351. If an external force greater than the restoring force of the spring 314 is applied to the first sequin guide 310, the first sequin guide 310 is spaced apart from the first sequin gear 351. That is, although the first sequin guide 310 is normally kept in contact with the first sequin gear 351 by the restoring force of the spring 314, when the first sequin band 371 needs to be replaced or checked, The first sequin guide 310 may be spaced apart from the first sequin gear 351 by applying a force greater than or equal to the restoring force of the spring 314 from the outside.

Sequin supply device according to another embodiment of the present invention surrounds a part of the outer periphery of the bobbin 411, the first sequin band 371, bobbin 411 wound along the outer periphery of the bobbin 411, the other part is open The outer frame 410, and a plurality of auxiliary rollers (412, 413, 414) are installed in the outer frame 410 to contact the outer periphery of the bobbin 411 and to guide the rotational trajectory of the bobbin 411. .

The plurality of

auxiliary rollers

412, 413, and 414 support the bobbin 411 at three or more outer circumferences of the bobbin 411, so that the bobbin 411 is not applied to the bobbin 411 from the outside. ) Provides a predetermined counter force so that the position of the bobbin 411 is fixed without leaving the outer frame 410.

According to the present invention, in the sequin sealing process, any one of a plurality of sequin bands is selected and supplied to the fabric fabric, and a plurality of sequin bands can be prevented from being entangled. According to the multi-sequin guide device of the present invention, only the selected sequin band is supplied to the fabric fabric, and the remaining unselected sequin bands are not supplied to the fabric fabric and remain stationary. As a result, the phenomenon in which the sequin bands that are not selected are unnecessarily supplied can be prevented, and the sequin bands can also be prevented from being entangled.

The multi-sequin guide device of the present invention can supply only the selected sequin bands to the fabric fabric while driving all the sequin gears by one rotating shaft. Therefore, the multi-sequined guide device of the present invention can select and supply one of two or more sequins, and expand and deform the sequin bands that can be selected according to the structure of the guide cam device to two, three, or four or more. Can be. Even if the number of sequin bands is increased, the rotating shaft can use the two axes for driving the sequin gear and the guide cam device as it is, so that the additional cost required for increasing the number of sequin bands can be reduced.

In addition, according to the present invention, the sequin band which is not sealed is spaced apart from the sequin gear, but is fixed by the inner guide and the outer guide of the sequin guide so that the sequin band is supplied between the needle and the fabric without error when the sequin band is selected again in the future. Can be.

In the case of the prior art, the selective supply of the sequins was not smooth when the sequins had different sizes as well as the colors of the sequins. This is because the sequins are entangled by the frictional force between the sequins, or the sequin supply roll 204 is driven by the same drive shaft so that all the sequins are supplied to the fabric. However, according to the present invention, even when the size of the sequins is different, the selective supply of the sequins can be free. This is because if the size of the sequins is different, the size of the teeth of the sequin gears can be changed accordingly, and the rotation speed can be set differently. In addition, in the sequin feed roll 204 of the prior art, the sequin wound feed roll 204 or bobbin (bobbin) is connected to the same shaft, even when one sequin feed roll 204 or bobbin is to be replaced or checked There was an inconvenience in that the sequin feed roll 204 or bobbin had to be separated.

On the other hand, when the sequin is defective or the embroidery pattern itself is changed and the sequin needs to be replaced, the sequin guide device having the hinge coupling structure of the present invention is easy to replace the sequin. In addition, by using the sequin supply device of the present invention, only the bobbins in which the sequins are wound can be selectively or individually removed for replacement or inspection.

The inner guide 312 engages with the spring 311 to push the first sequin band 371 outward. Since the spring 311 is forced in the pressing direction, the spring 311 and the inner guide 312 push the first sequin band 371 outward by the restoring force.

The first sequin guide 310 further includes an outer guide 313 that supports the first sequin band 371 from the outside. The outer guide 313 prevents the first sequin band 371 from escaping from the first sequin guide 310. The outer guide 313 may be implemented in the form of a guide jaw, or may be implemented in the form of a cover for the first sequin band 371. When a force is not applied to the first sequin band 371 from the outside, the first sequin band 371 is formed by the frictional force between the inner guide 312 and the outer guide 313. Is fixed between). Thus, when the first sequin band 371 is not selected, the position of the first sequin band 371 is fixed, and the position is maintained until the first sequin band 371 is selected again. Therefore, when the first sequin band 371 is selected again, the first sequin band 371 may be accurately engaged with the cog wheels of the first sequin gear 351.

It is assumed again that the first sequin band 371 is selected. At this time, the first sequin band 371 is attracted by the rotational movement of the first sequin gear 351. In this case, since the force applied to the first sequin band 371 by the first sequin gear 351 is greater than the friction force between the inner guide 312 and the outer guide 313, the first sequin band 371 is made of a fabric fabric. Guided in the direction.

Meanwhile, one side of the first sequin guide 310 may be pivoted in combination with the hinge shaft 361 installed on the main plate 360. The other side of the first sequin guide 310 is connected by the support 315 and the spring 314 installed on the main plate 360. The spring 314 pulls the first sequin guide 310 so that the first sequin guide 310 maintains contact with the first sequin gear 351. If an external force greater than the restoring force of the spring 314 is applied to the first sequin guide 310, the first sequin guide 310 is spaced apart from the first sequin gear 351. That is, when the first sequin guide 310 is normally kept in contact with the first sequin gear 351 by the restoring force of the spring 314, when the first sequin band 371 needs to be replaced or checked, The first sequin guide 310 may be spaced apart from the first sequin gear 351 by applying a force greater than or equal to the restoring force of the spring 314 from the outside.
