Operating method of an embroidering machine

Abstract

The present invention relates to an operating method of an embroidering machine comprising a thread feeder, a needle working unit having a needle, a thread feeding unit forming a thread transferring path and having an upper thread feeder and a threader, a cut -thread sensor to sense whether the upper thread is cut, and a cutting unit to cut the upper thread, the operating method comprising controlling the cut -thread sensor to sense whether the upper thread is cut; stopping the needle working unit to operate; recovering the cut upper thread from the needle working unit; and driving the upper thread feeder to feed the needle working unit with a new upper thread to be threaded through the needle. Thus, it is possible to reduce time taken to feed a needle working unit with an upper thread when the upper thread is cut, thereby enhancing productivity and implementing an automation system thereof .

Description

technical field [0001] The present invention relates to an operation method of an embroidery machine, more particularly, relates to an operation method of an embroidery machine, which detects whether the thread is broken during operation, and stops the operation when the thread is broken, so as to automatically replace the new upper thread Go through the eye of the needle. Background technique [0002] Generally, an automatic embroidery machine includes: a head stem disposed in front of a mounting frame; a thread feeder mounted to the head and feeding upper threads of various colors on a plurality of bobbins in the direction of embroidery work device; and a needle working unit for performing embroidery work by sewing needles with supplied upper thread. [0003] In addition, automatic embroidery machines are classified into a single-needle type and a multi-needle type according to the number of needles installed to the thread feeding device and the needle working unit.

AI Technical Summary

Problems solved by technology

[0009] However, in this conventional automatic embroidery machine, when the upper thread is disconnected during normal embroidery work, in order to supply the needle with the disconnected upper thread again, the user manually passes the upper thread through the eye of the needle, and then restarts the embroidery machine.

Therefore, it takes a considerable amount of time to pass new upper thread through the eye of the needle and restart the embroidery machine, that is, to replace the broken upper thread with new upper thread, so that the traditional embroidery machine reduces productivity and it is difficult to implement an automated system
