摘要
多缸单往复行程程序控制回路的设计关键之一障碍信号的排除,在气缸数少的回路中,用信号-动作状态图法较好解决制约信号、中间记忆元件的控制信号的选择问题,简单而且直观;在多气缸回路中,用串级法设计的气动回路控制准确,不易出错。
The two ways of obstacles elimination to the signal process action sequence were introduced, such as Signal-Action Figure state law and Cascade law. Pneumatic loop system can be controlled accurately and also can be operated and modified easily by choosing restrictive signal and control signal of middle memorial component.
