摘　　要：传统的物料分拣设备采用在料槽上方分别安装传感器,并当相应的传感器动作时通过PLC驱动气缸进行推料的控制模式,这种模式只能分拣单一颜色或材质的工件,存在较大的局限性。针对上述问题,提出了使用西门子CPU224XP型PLC作为控制器,结合传感器、气动技术、旋转编码器和变频器构成组合工件自动分拣系统的设计方案,系统可以对较为复杂的组合工件进行分拣。经实践运行测试,该系统工作效率高、运行可靠,有较强的实用性和较大的应用推广价值。Traditional material sorting equipment takes the mode of using sensor installing above the trough to drive the cylinder with PLC, which could only sort a single color or the material of existed large limitations. To solve the above prob- lem, provide the design of a combination of workpiece automatic sorting system, which can sort more complex ones by using Siemens CPU224XP type PLC as the controller and sensor. The system also includes pneumatic technology, rotary encoder and frequency converter. It has been proved by practice that the system has high efficiency, reliable operation, strong prac ticability and great application value.
