Analysis on A New Traverse Yarn Device for Precision Winding and Its Control

介绍了一种精密卷绕的新型横动导纱装置,该装置由两个连续旋转运动的普通步进电机互相协同,带动钢丝绳的往复运动,完成精密卷绕的横动导纱。从理论上分析了两个电机互相协同运动并保证定速导纱的控制原理,从硬件设计和软件策略两个方面,提出了该装置定速横动控制的实施方案,并在BS-10S松式络筒机上进行了实际测试,对测试中出现的问题给出了调整与改进的方法,取得了与理论分析相符的实际控制效果。

A new traverse yarn device for precision winding is introduced in this paper.This device runs together with two common stepping motors with continuous rotation,which drives the reciprocating motion of wire rope to finish traverse yarn guidance for precision winding.This article theoretically analyzes the control principle of synergic movement of the two steeping motors to ensure the constant-speed yarn guidance.An implementation plan of constant-speed traverse control is proposed from two aspects(hardware design and software strategy).Practical test is done with BS-105 spooling machine and the adjustment and improvement method is proposed for the problems in the test.The actual control results are consistent with the theoretical analysis.
