A monitoring method for broken yarn splicing of spinning frame

Abstract

The invention relates to the field of spun yarn textile, in particular to a method and device for automatically detecting broken ends and jointing ends for spun yarn. The method for automatically detecting the broken ends and jointing the ends for the spun yarn comprises the steps that a guide rail and a movable trolley are additionally arranged beside a steel collar board, the movable trolley isprovided with a thread bobbin for lead threads, a controller controls the movable trolley to conduct reciprocating movement on the guide rail, an inductance coil probe detects the broken ends, and a mechanical arm utilizes a section of cut lead thread to connect a virtual strip with a yarn bobbin. By means of the method and device for automatically detecting the broken ends and jointing the ends for the spun yarn, a traditional thread connection mode is changed without pulling out the yarn bobbin rotating at a high speed or looking for the broken ends, the automatized operation of jointing thespun yarn can be achieved just through a section of cut lead thread, and accordingly a lot of manpower is saved.

Description

technical field [0001] The invention relates to the field of spun yarn textiles, in particular to a method and device for automatic detection of broken ends and automatic splicing of spun yarns. Background technique [0002] Spinning is a labor-intensive industry, and the spinning process employs the most people. At present, their main job is to connect the broken ends, because if the broken ends are not connected in time, the production will be affected, and the cashmere will be produced, causing a lot of waste. But connecting broken ends is a laborious and technically demanding job, and only skilled workers can do it. The current method of operation is to unplug the bobbin from the high-speed rotating spindle, find out the broken end, and then insert the bobbin back into the joint On the spindle, it is really difficult to accomplish if manipulators are used to imitate the splicing according to the above-mentioned operation method, so there is no automatic splicing device ...

At present, their main job is to connect the broken ends, because if the broken ends are not connected in time, it will affect the production and produce piles, causing a lot of waste

But connecting broken ends is a laborious and technically demanding job, and only skilled workers can do it. The current method of operation is to unplug the bobbin from the high-speed rotating spindle, find out the broken end, and then insert the bobbin back into the joint On the spindle, it is really difficult to use manipulators to imitate the manual jointing according to the above operation method, so there is no automatic jointing device for spun yarn so far
