啤酒清洗灌装控制系统设计摘要本设备是专为啤酒桶的清洗、消毒设计的。该设备可以自动完成清洗消毒及CO2备压等全部工序。本设备适用桶的尺寸为高度H360—H560，直径Φ250—Φ500。本机主要由机架、电气控制箱、电磁阀、气动元件、气冲系统和水路系统组成。本机控制单元采用以三菱公司的可编程控制器为核心对机器进行全过程控制。由于可编程控制器在工业控制方面的应用意义日趋明显，已在机械制造、发电、化工、电子等行业工艺设备的电气控制方面得到了广泛的应用。它具有功能强大、使用可靠、维修简单等许多优点，并且在很多地方已逐步取代了继电器电路的逻辑控制。本文讨论的是PLC在实际工业控制系统的应用。关键词：ＰＬＣ；管路系统；清洗机BeerCleaningFillingControlSystemDesignAbstractThisequipmentdesignedforcleaningandsterilizingcasks.Theequipmentisautomatic.Thekeyprocessescontaindischargingremnants,swillingwithwater,swillingwithdisinfectant,swillingwithasepticwaterandinflatingwithCO2.Theheightofcaskis360—560.Thediameteris250—500.Theequipmentismadeofchassis,controlunit,electromagneticvalveandpiping.ThecenterofmanipulativeunitistheMITSUBISHIPLC.PLCcontrolsalloftherunningprocesses.Appliedmeaningthatprogrammablelogiccontrollerhaveinitscontroltheaspectintheindustrygraduallyobvious,combineatmanufacture，generateelectricity,chemicalengineering,electronicsetcprofessioncrafttheequipment'selectricitycontroltheaspectgottheextensiveapplication.Ithavethefunctionstrongandbig,theusageisdependable,maintainthemanyadvantageofsimpleetc.,andalreadyandgraduallyreplacedafterthelogiccontroloftheelectricapplianceselectriccircuitinalotofplaces.ButwhatthetextdiscussionisaPLCintheactualindustrytocontrolthesystem'sapplication.KeyWords:PLCPipingCleaningMachine目录摘要..................................................................IAbstract...................................................................II目录..................................................................III插图清单....................................................................V表格清单...................................................................VI引言........................................................................1第1章绪论.................................................................21.1本课题设计的背景.........................................................21.2本课题设计的内容.......................................................21.3本课题设计的目的和意义...................................................3第2章系统总体设计方案.....................................................42.1清洗机..................................................................42.2清洗机的用途特点........................................................42.2.1清洗机用途及使用范围...............................................42.2.2清洗特点...........................................................42.3总体要求.................................................................5第3章PLC控制系统方案设计..................................................63.1PLC控制系统设计的基本原则...............................................63.2PLC的选型...............................................................63.2.1控制功能..........................................................63.2.2I/O模块及点数.....................................................73.2.3PLC输出类型选择...................................................73.3水位控制器......................................................
