多级物料传输带控制系统的设计与制作【摘要】本设计采用 PLC(可编程控制器）来实现货车进站开启出仓口送出物料，建立一个模拟系统硬件模型，通过传送带将物料从高处传送到低处，最后货车将物料送走。能实现货车进站，启动开仓口；物料出仓，传送带将物料从高处逐层送到低处；物料传送到货车后厢，传送完毕，货车开走。系统不但考虑到几个皮带机之间的时间间隔，还考虑到了当某台皮带机出现故障时的解决办法，达到有效的自动控制，优化运行效果，减少运行费用等目的。 【关键词】PLC; 传送带；物料传送1AbstractThis design USES PLC(programmable logic controller) to realize the truck to enter the station and open the outlet of the warehouse to send out the materials. It establishes a hardware model of the simulation system to transfer the materials from the high place to the low place through the conveyor belt. Finally, the truck sends the materials away. Can realize the truck to enter the station, start the warehouse opening; Materials out of the warehouse, the conveyor belt will be layer by layer from the height of the material to the lower place; The material is transferred to the back of the truck. The system not only considers the time interval between several belt conveyors, but also considers the solution when a belt conveyors break down, so as to achieve effective automatic control, optimize the operation effect and reduce the operation cost.【 key words 】PLC; The conveyor belt. Material transfer2引 言 传输带是一种连续、快速、高效的物料传输设备,广泛应用于煤炭、电力、建材、化工、机械、轻工业等行业的物料传输系统。一般传输带的电气控制系统采用硬接线方式的继电器控制系统,设备故障率高、可靠性低、体积大、维修和改造不方便。本文介绍一种传输带的PLC 控制系统。PLC( Programmable Logical Controller) 即可编程逻辑控制器,是微型电子计算机与常规控制元件,如继电器等互相结合形成的新型工业自动化控制装置。它是在一位机、顺序控制器和计算机控制的基础上发展起来的;把继 ...
