Description

Probe type spinning frame single spindle broken end detection device

Technical Field

The utility model belongs to the technical field of the yarn broken end detection technique and specifically relates to a probe-type spinning frame list spindle broken end detection device is related to.

Background

The spinning process of a spinning mill is a key process influencing yield and quality, yarn breakage is caused by various factors in the spinning process, raw material waste, yield reduction, flying increase, cost increase and quality reduction can be caused, and the traditional solution is to continuously perform itinerant inspection by a vehicle stopping worker to find the breakage and timely treat the breakage. Due to the randomness of the broken ends in the spinning process of the spun yarns, in order to find and process the broken ends in time, only the working mode that a car stop worker looks at a table surface and does not need to perform itinerant inspection continuously can be adopted, the working mode depends on manpower seriously, the working mode is more in labor, the working strength of the car stop worker is high, and the counting of the broken end distribution and the analysis of the broken end reasons are not facilitated. The method has the advantages that the broken ends of the spun yarns are automatically detected, the detection result is informed to a vehicle stop worker to carry out timely and efficient processing, the broken end distribution and the number are subjected to statistical analysis, and the method is an urgent requirement for intelligent spinning.

The single spindle broken end automatic detection technology of the spinning frame at the present stage mainly comprises the following methods:

firstly, at the ring side-mounting sensor of every spindle, judge whether broken end through the moving speed that detects the wire winding on the ring, when taking place the broken end, detect the wire winding stall, send the broken end signal and instruct the spindle position, inform the stop buffer worker to handle. The sensor can adopt a photoelectric type or an induction type, the detection mode can not only find broken ends, but also give an alarm when the speed of the spindle is lower than a set value. And secondly, a photoelectric sensor is arranged at the position of the thread guide hook of the lappet to detect the state of the balloon, and when the spun yarn breaks, the broken end signal is sent out when no balloon is detected. The two modes of detection are related to the rotation of the steel wire ring, when the yarn is broken, a certain time difference exists between the broken end and the stop of the rotation of the steel wire ring, so that the broken end is not conveniently and quickly found, and the production is influenced. And thirdly, the broken ends are detected by adopting the reciprocating motion of the movable trolley on the guide rail, the probe arranged on the trolley is contacted with the yarn, and the broken ends of the spun yarn are detected through the moving distance and the contact counting.
