多级物料传输带控制系统摘要：在工厂装配线上和产品运输过程中，常常使用多级的输送带。在以前的继电器控制系统中，电路的修改和维护非常困难。通过 PLC 对输送带的控制系统进行了修改，很大程度上提高了生产的效率，节省了人工成本，大大提高了自动化程度。本课题主要使用 PLC 来进行货物进站开仓运送，构造模拟的系统硬件模型，通过输送带将物料从高处输送到低点，最后卡车送出把材料。它可以实现卡车进站并启动开口;物料从仓库出来，传输带将物料从高处送到下部;材料被转移到卡车的后舱，传动装置完成，卡车离开整个过程。该设计不仅想到了多台皮带输送机之间的时间间隔，还研究了皮带输送机出现问题时的解决方案，实现了有效的自动控制，并且对运行的结果进行了优化，降低了运营成本。关键词：传输带；控制系统；设计Multi-stage material conveying belt control systemAbstract ：Multistage conveyor belts are often used in factory assembly lines and product transportation. In the previous relay control system, it was very difficult to modify and maintain the circuit. The control system of conveyor belt was modified by PLC, which greatly improved the production efficiency, saved labor costs and greatly improved the degree of automation. In this project, PLC is mainly used to transport goods into and out of the warehouse, and a simulated system hardware model is constructed. The material is transported from high to low point by conveyor belt, and finally the material is delivered by truck. It can realize the truck entering the station and starting the opening. Material comes out of the warehouse, and the conveyor belt transports the material from high to low. The material is transferred to the rear compartment of the truck, the transmission is completed, and the truck leaves the whole process. The design not only considers the time interval between multiple belt conveyors, but also studies the solutions to problems of belt conveyors, realizes e...
