摘要: 介绍超重多臂织机控制系统的功能及软件与硬件构成,其多臂装置有20片综,分别由20支气缸控制拉钩升降,织机左右各有3个梭箱,且左右各有2个气缸控制梭箱升降传动装置,投梭方向则由安装在织机两侧的投梭吸铁控制。分析了利用PLC实现控制超重多臂织机的具体方法,采用光电编码器反馈织机主轴转角,TD200文本显示器作为人机界面,实现电子纹板的编辑输入和织机工作状态的监控显示,使织机具有电子多臂、电子多梭箱控制以及任意投梭控制功能,给出织机工作的时序图和控制系统主程序流程图。

Abstract: This paper describes the software and hardware composition of the overweight dobby loom control system,there are 20 harnesses whose lifting is controlled by 20 air cylinders on the dobby device,and 3 shuttle boxes on both right and left sides of the loom,the gearing of shuttle box on each side is controlled by 2 air cylinders and the direction of picking is controlled by one electromagnet.The specific method on the overweight dobby loom′s control system is realized,the loom shaft angle is fed back by a photoelectric encoder,the input and edition of electric pattern card is realized and all process parameters are displayed on human-machine,so the loom is provided with multi-function such as electronic dobby device,electronic multi-shuttle box control and picking control.Besides,the loom′s working sequence and the flow chart of control system is given.
