Description

Spangle Feeder {SPANGLE SUPPLING APPARATUS}

The present invention relates to a spangle supply apparatus, and more particularly, to a spangle supply apparatus capable of being attached to a head of an embroidery machine and capable of supplying a plurality of spangle tapes individually and simultaneously.

In general, it is recognized as a high value-added product when a spangle of thin plate formed into various shapes such as round, polygon, and heart shape is added to the embroidered fabric, compared to the fabric simply embroidered using various colored yarns. I am getting it.

These spangles are mainly applied to women's fabrics, clothing, footwear, ornaments, etc., and are mainly made of PVC or 100% polyester, etc., as a main raw material, compared to metal, and usually spangles are manufactured in the form of a continuously formed tape.

The spangle supply device for supplying such a spangle is to transfer the spangle tape to a predetermined pitch and cut it individually, so that the spangle is sewn at the desired position of the fabric and attached to the embroidered fabric.

By the way, the prior art is a computerized automatic embroidery machine for new or used for single or plural spangle devices (single device) of a new or used computerized single or plural embroidery machine, regardless of the product name and manufacturer. In any brand '), because the spangle signal is received from the main controller (CPU) of the existing embroidery machine, the spangle signal system differs according to the manufacturer, so that each board has a separate electronic board for receiving the spangle signal. It requires a lot of initial investment cost, and in the case of the old embroidery machine, there are many problems in communication due to the mounting operator and the aged electronic parts of the CPU board of the existing embroidery machine. There is a serious problem of giving electrical / electronic loads to existing embroidery machines. In addition, by adjusting all the heads with one controller, when a problem occurs in the controller, there is a problem that all the heads can not perform the operation.

In addition, the spangle tape used in the spangle mounting apparatus is manufactured in different thickness standards even though the spangles commonly used in the same specifications according to the coating process of each manufacturer or each manufacturer. In the case of using different kinds of spankle tapes, it is difficult to transfer the spangle to the needle side or to accurately guide the spangles, and thus, it is difficult to seamlessly sew sequins during embroidery.

Furthermore, when replacing with a spangle tape having a wider or narrower width than the previously used spangle tape, the conventional spangle supply unit corresponds to the width of the replaced spangle tape, so that the entire unit must be replaced. There was a problem that the work efficiency is reduced, such as delay.

In addition, after the wiper is operated by raising the spangle supply device for free operation of the wiper (upper thread pulling device) that is operated when trimming, the spangle supply device is moved after the vertical operation in the process of lowering the spangle supply device. Since the position is changed and the exact position is not set, this also acted as a factor to lower the product quality and productivity.

Due to this problem, the conventional design has a limitation of moving to running stitches when moving to another work point after trimming because it is fixed to prevent the vertical operation from trimming.

In addition, when the embroidery is resumed after a power failure or when the job is finished, the Spangle origin is different from the previous operation, and the power is turned on 24 hours or the operator manually restarts each power supply after the power is turned on. There was an inconvenience to adjust the origin.

On the other hand, when sewing a spangle with a small diameter spangle on the upper surface of the large diameter spangle, sew a large diameter sequin firstly, and then replace with a small spankle tape. It had to be sewn overlaid on top of a sewn large diameter sequin.

Therefore, it is very difficult to sew two spangles having different diameters as a conventional spangle supply device, and it is impossible to simultaneously supply and sew two spangles.

Therefore, the problem to be solved by the present invention is to supply and cut the spangle tape of different specifications at the same time, the two spangles are piled up so that the operation of the sewing process by sewing very quickly to increase the efficiency It is to provide a spangle feeder that can be improved and improved in productivity by processing a large amount of spangle sewing work in a short time.

When the spangle is positioned at the tip of the base 43, the cutting knife 51 cuts the extracted spangle.

That is, while the needle bar 8, which is lowered together with the needle 7 of the embroidery machine, presses the upper end of the cutting knife 51, the cutting knife 51 is rotated downward, and at this time, the cutting knife 51 is located at the end of the protruding surface 44d. The spangle is cut while the cutting hole 51a corresponds to the protruding surface 44d, and the spangle located at the tip of the base 43 is cut while the lower end of the cutting knife 51 corresponds to the tip of the base 43. do. Thereby, the cutting knife 51 is rotated downward, and simultaneously cuts the spangles of each of the two spangle tapes 4 and 4 '.

As described above, two spangles having different diameters are cut and at the same time, the needle 7 of the embroidery machine is sewn into the fabric in a state in which the two spangles are cut.

As described above, the spangle supply apparatus 100 according to an embodiment of the present invention may be simultaneously sealed so that two spangles having different diameters are superimposed, and the two spangles may be repeatedly repeated depending on whether the controller 70 is set. You can also take turns sewing.

Meanwhile, as described above, the power supply is cut off while the spankle tapes 4 and 4 'are continuously supplied, or the elevating unit (e.g., the driver is pre-programmed in the controller 70 when the spangle or the embroidery thread is trimmed). The elevating member 12 of 10 is waited in the elevated state.

In addition, when the power supply is cut off due to a power failure or the like during the supply operation of the spangle tapes 4 and 4 ', or when the spangle supply apparatus 100 is stopped when the spangle or the embroidery thread is cut off, the power is supplied again to the spangles. If the spangle origin is at a different position from the previous operation when the embroidery is resumed, the controller 70 which has received the detection signal through the sensing unit 35 is the origin of the spangle, i.e., the pre-recorded program. The stepping motors 31 and 31 'are driven to rotate so that the spangle is automatically positioned at the cutting position where it can be cut accurately.

In this way, when the power supply is re-supplyed after the power is cut off, the cutting position of the spangle can be set automatically, and the stepping motors 31 and 31 'are rotated forward or reverse by operating the control switch 80. You can also set the cutting position.

Therefore, the spangle supply apparatus according to an embodiment of the present invention is capable of simultaneously supplying and cutting spangle tapes 4 and 4 'of different sizes having different diameters of spangles. The process of overlapping sewing can be done very quickly to improve the efficiency of spanking sewing operations and the productivity can be improved by processing a large amount of spangle sewing operations in a short time.
