本論文闡述了利用松下電工生產(chǎn)的一種小型PLC—FP0結(jié)合氣動(dòng)、傳感器和位置控制等
技術(shù)，并運(yùn)用梯形圖編程，實(shí)現(xiàn)對(duì)鐵塊、鋁塊及藍(lán)色、黃色兩種塑料塊共四種材料的自動(dòng)分揀。該系統(tǒng)的通用性極強(qiáng)，可靠性好，程序開發(fā)簡(jiǎn)單，可適應(yīng)進(jìn)行材料分揀生產(chǎn)線的需求。
文中主要介紹了系統(tǒng)的硬件及軟件設(shè)計(jì)。
Abstract ：The paper explained how to combine the mini PLC-FP0 that was made by Panasonic with pneumatic sensor and position control technology and program with
the ladder—shape figure, designing the automatic system that sorts out iron、 aluminum 、yellow plastics and blue plastics . The flexibility of this system is fine, the reliability is also excellent and programming is easy. It adapts to elasticity production line for materials sorting. The design of hardware and software are introduced emphatically in the paper.
Key words：PLC；Automatic Sorting System；The Ladder-shape Program
