基于PLC的柔性制造系统供料站设计

摘要

供料站是柔性制造系统中的起始工作站，起着向整个系统中各工作站提供原料的作用。该文提出以西门子S7-200 PLC作为控制器，以SMC气动元件作为执行机构的柔性制造系统供料站设计方案，详细论述了供料站的硬件系统构成、气动控制回路、程序设计流程及实现方法。%Feeding station is the starting station in flexible manufacture system, which played the role of supplying other workstations in the whole system with raw material. In this paper, providing the design of feeding station of flexible manufacture system with the Siemens S7 -200 PLC as the controller and SMC pneumatic components as the executive mechanism. The feeding station was described in detail the hardware system structure, pneumatic control loop, the program design process and implementation meth-od.
