Description

TECHNICAL FIELD [0001] The present invention relates to a method of automatically changing a bobbin capsule of an embroidery thread,

More particularly, the present invention relates to a method for automatically changing a bobbin bobbin capsule of an embroidery machine, and more particularly, to a bobbin bobbin capsule pulling machine which draws a bobbin bobbin capsule from a computer shuttle, And more particularly, to a method and apparatus for automatic replacement of bobbin bobbin capsules in an embroidery machine that can greatly improve the productivity of an embroidery machine by automating the winding of a bobbin capsule around a recovered bobbin capsule and rewinding the bobbin capsule wound around the bobbin to the north shuttle.

Generally, in the computerized embroidery machine with multiple embroidery heads, removing the lower thread bobbin capsules which are released from the lower thread and replacing the lower thread bobbin capsules with the lower thread is done while the computer embroidery machine is stopped, Which is made at the lower part of the embroidery machine, not only greatly deteriorates the productivity, but also has been carried out manually by a skilled worker.

The bobbin capsule exchanger disclosed in the U.S. Patent No. 4,223,618 and the U.S. Patent No. 5,694,874 is relatively complicated in structure and relatively large in size so that it can be applied to a general sewing machine, It is difficult to apply it to a computer embroidery machine arranged in the same manner as the above, but also the manufacturing cost is high, the maintenance cost is high, and the number of constituent parts is large.

Japanese Patent Application Laid-Open No. 07-27555 and Korean Patent No. 10-0711076 disclose an apparatus for drawing a bobbin bobbin capsule having a lower thread pulled out by using the magnetic force of a permanent magnet or an electromagnet from a northern shuttle of a sewing machine. Reloading the bottom threaded bobbin capsule with the bottom thread to the north shuttle still depends on the manual operation so that it is not suitable to be applied to the computerized embroidery machine and the productivity of the computerized embroidery machine is still insufficient.

The object of the present invention is to automate the withdrawal of the extracted bobbin capsule as well as withdrawing the extracted bobbin bobbin capsule from the north shuttle by using the magnetic force and reloading the bobbin capsule with the bobbin wrapped around the north shuttle, And to provide a method and an apparatus for automatically replacing a bobbin bobbin capsule of an embroidery machine that can upgrade an existing computerized embroidery machine to an improved productivity computer embroidery machine at a lower cost by simplifying the structure and structure of the bobbin.
