The electromechanics of spun yarn based on PLC accuses of designing partly
Abstract
It is end lines of process to spinning course for spun yarn not to produce, spinning frame spin certain spun yarn of number of yarn roving or strip yarn, available for twisting thread , the machine is woven or knitting. The spinning frame plays a very important role in production, the cost that the stability of controlling systematic function influenced production directly. It is to control the outdated relay while the spun yarn produces of before to originally design, make into and control with PLC with higher automatic degree, realize to launch , start , stop , fall yarn and is it control function mainly to stop promptly ahead of time midway at a high speed at a low speed spinning frame on this basis; Realize the electrical machinery is started in order strictly, overload protection and leaking electricity to protect etc. and protect the function; Realize low-speed operation state point out , high-speed operation state point out , full yarn point out , is it shut down alarm signal instruction , warning function to send out according to trouble nature, realize stability of the spinning frame , reliable , safe operation finally.
