摘 要随着社会的不断进展,市场竞争越来越激烈,因此各个生产企业都迫切地需要改进生产技术。在需要进行产品分拣的企业,以往一直采纳人工分拣的方法,效率低下致使企业的竞争能力差。针对上述问题,利用 PLC 技术设计了自动分拣装置,在产品分拣过程中取得较好的控制效果。本设计应用 PLC 实现具有传输、分类、入库保管功能自动分拣系统的自动控制系统并应组态做上位机监控,机械结构采纳传送带、气缸等机械部件;电气控制采纳传感器、编码器、开关电源、换向阀等电子部件;可编程控制器采纳目前比较流行的西门子 PLC。软件部分采纳组态王监控整个分拣过程的运行,系统采纳台式结构,选用颜色识别、电容式和电感式三种传感器,同时,还设置了气动装置的减压器、滤气器、气压指示等,可与各类气源相连接。本设计是将 PLC 技术,位置控制技术、气动技术、组态通讯监控技术有机结合成一体的自动输送分拣系统,具有响应速度快,准确率高、性能可靠等优点。关键词:PLC;传感器;编码器;自动分拣系统;上位机监控Abstract With the continuous development of society, the competition is fierce in the market, Therefore production enterprises are urgently needed to improve production technology especially in the enterprise products sorting,has been using an artificial of sorting method before cause the competitive of the enterprise is poor. The response to these problems, to use PLC technology design of automatic sorting equipment, obtains good control effect in the process of product sorting. The design applies PLC to achieve automation control Automatic Sorting System which have functions of transfers、classify and storage, the mechanical structure adopts mechanical assembly as conveyor belt 、 cylinder. The electric control adopts electronic assembly as sensor 、 coder 、 switching power supply 、 reversing valve and so on; Programmable logic controller adopts the more popular PLC of Siemens currently. The system adopts desktop structure, choose color recognition sensor 、capacitive proximity switch...
