[0002] As the last process in the spinning process, the fine yarn process is mainly used for completing drafting, twisting and winding.

In the fine yarn installation single spindle detection, proximity switches are usually installed at the large shaft, the roller and the doffing position to monitor and feedback the state of the spindles in real time. When the spindles are running normally, the proximity switches can sense the movement of the spindles and output corresponding signals. Once the spindles stop running due to breakage or other faults, the proximity switches cannot sense the movement of the spindles and output fault signals. After the control system receives the fault signals, the buzzer or the indicator light alarm device is triggered to prompt the operator to handle the fault in time, so that the production interruption caused by the spindle fault can be avoided and unnecessary losses can be reduced.
