基于PT/PLC的瓜果去皮生产线智能控制系统设计
Design of intelligent control system of production line for fruit peel based on PT/PLC
摘要
Abstract
Peeling is an important procedure in the deep processing of melon and fruit,where positioning accurately and peeling dynamically are two key issues to be resolved.Taking the automatic production line of white gourd peeling as an example,design the intelligent control system.The system uses the laser displacement sensor for precise position control,and gets accurate position information via PLC for AC servo unit to control related mechanical action.Dynamic peeling is realized by controlling the feed of cutting tools according to the tiny displacement variation on the surface of fruit picked up by small displacement sensor of differential transformer as imitation shaped probes and by instrument amplifier and phase-sensitive rectifier circuit.The results indicate that the designed system has high positioning accuracy and excellent peeling effect.关键词
