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。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 fight 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.
