基于PLC的自动包装码垛生产线的研究与设计
|
摘要
目的为了提高固体颗粒物料的包装及包装袋码垛效率,降低企业工人的劳动强度。方法以西门子PLC S7-1200为控制核心,结合数字输入SM321、数字输出SM322等模块,设计一套自动包装码垛生产线,用于粮食、化肥等物料的自动包装和码垛。通过设计伺服电机驱动、传感器输入模块、触摸屏人机交互界面等来实现对生产线的自动控制。结果在完成生产线固体物混料装置、包装袋称量装置以及码垛机器人的基础上,进行化肥的包装实验,记录了包装袋称量误差以及码垛的中心误差,分析发现中心抓取误差小于0.2 mm。结论该生产线系统可靠性强、包装码垛精度高,能够大大提高包装和码垛效率,具有很大的市场应用前景。
The paper aims to improve the packaging and the stacking efficiency of packaging bags for solid particles and reduce the labor intensity of enterprise workers. With the Siemens PLC S7-1200 as the core, combined with the digital input SM321, digital output SM322 modules, a set of production line was designed for automatic packaging and stacking of food, fertilizer and other materials. Through design of servo motor drive, sensor input module and touch screen manmachine interface, the automatic control of production line was realized. Upon completion of production line solid mixing device, packaging bag weighing device and stacking robot, the packaging experiment of fertilizer was carried out on this basis. The weighing error of packaging bags was recorded and the center error of stacking was analyzed. The grabbing error was less than 0.2 mm. The control system has high reliability and high precision of packing stacking, which can greatly improve the efficiency of packing and stacking, and has a great market application prospect.
