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-stagematerialconveyingbeltcontrolsystemAbstract：Multistageconveyorbeltsareoftenusedinfactoryassemblylinesandproducttransportation.Inthepreviousrelaycontrolsystem,itwasverydifficulttomodifyandmaintainthecircuit.ThecontrolsystemofconveyorbeltwasmodifiedbyPLC,whichgreatlyimprovedtheproductionefficiency,savedlaborcostsandgreatlyimprovedthedegreeofautomation.Inthisproject,PLCismainlyusedtotransportgoodsintoandoutofthewarehouse,andasimulatedsystemhardwaremodelisconstructed.Thematerialistransportedfromhightolowpointbyconveyorbelt,andfinallythematerialisdeliveredbytruck.Itcanrealizethetruckenteringthestationandstartingtheopening.Materialcomesoutofthewarehouse,andtheconveyorbelttransportsthematerialfromhightolow.Thematerialistransferredtotherearcompartmentofthetruck,thetransmissioniscompleted,andthetruckleavesthewholeprocess.Thedesignnotonlyconsidersthetimeintervalbetweenmultiplebeltconveyors,butalsostudiesthesolutionstoproblemsofbeltconveyors,realizeseffectiveautomaticcontrol,optimizestheoperationresultsandreducestheoperationcost.Keywords：Transmissionbelt;Controlsystem;Design目录引言......................................................................................................31.绪论....................................................................................................31.1物料传输系统的功能及意义.....................................................31.2PLC的基本概念..........................................................................41.3PLC的基本结构..........................................................................41.4PLC技术特点及主要功能..........................................................51.5PLC控制系统的功能..................................................................61.6PLC的可靠性..............................................................................61.7PLC的应用领域..........................................................................71.8PLC控制的的优点......................................................................82.物料传输系统的整体设计................................................................82.1设计工作......................................................................................82.2工作原理图.................................................................................92.3物料传输系统控制结构及工作情况.......................................102.4传输带控制原理.......................................................................102.5传输带控制原理流程图...........................................................113.物料传输系统硬件设计..................................................................113.1系统的硬件部分..............
