基于PLC控制的全自动灌装机系统的设计

-I-摘要食品机械是专为食品工业提供服务的，大约有70%的包装机械是为食品包装提供服务的，最近几年饮料业迅速发展，市场对液体灌装设备的需求量增长迅猛。国内的包装机械起歩较晚,而国外发达国家的包装设备已经向高效率、高精度、高自动化程度方向发展，目前虽然采用引进一消化的发展模式能满足生产需求，但技术含量不高，特别是对光、磁和计算机等先进技术的应用较少，从而使得国内与国外相比在包装机械的包装精度和运行稳定性上还是存在着较大差距的。本论文以全自动液体灌装机作为研究对象，采用欧姆龙CMP1A型PLC对其控制系统进行软件设计，并利用组态王做出监控系统，实现基于欧姆龙PLC与组态王的控制系统。采用模块化的设计方法，对全自动液体灌装机的主要控制要求进行程序设计，由理瓶机、灌装机、封盖机和外围辅机构成的四块控制模块，再结合组态王软件开发设计出一种适合工厂流水线化作业的全自动灌装机控制系统界面，对灌装机的工作流程实现实时监控，实现控制系统的分块管理、集中控制的功能，实现了灌装生产高速化、精确化、智能化、多功能化以及操作界面人性化的要求。关键词：灌装机、PLC、组态王。-II-AbstractFoodMachineryisdesignedtoprovideservicestothefoodindustry,about70%ofthepackagingmachineryistoprovideservicesforthefoodpackaging,beverageindustrydevelopedrapidlyinrecentyears,marketdemandfortherapidgrowthofliquidfillingequipment.Domesticpackagingmachinerysincelatewalk,andpackagingequipmentindevelopedcountrieshasbeendevelopedtoahighefficiency,highprecision,highdegreeofautomationdirection,althoughthecurrentmodelofdevelopmentwiththeintroductionofadigestioncanmeettheproductionneeds,butnothigh-tech,inparticulartheapplicationoflesslight,magnetismandadvancedcomputertechnology,makingdomesticandforeigninthepackagingcomparedtheaccuracyandstabilityofpackagingmachineryrunningorthereisabiggap.Inthispaper,automaticliquidfillingmachineastheresearchobject,usingOmronCMP1AitstypePLCcontrolsystemsoftwaredesignandconfigurationkingmadeuseofmonitoringsystems,OmronPLC-basedcontrolsystemandconfigurationoftheking.Modulardesignapproach,themaincontrolrequirementsforautomaticliquidfillingmachineforprogramdesign,controlmoduleconsistsoffourUnscramble,fillingmachine,cappingmachineandperipheralauxiliarycomposition,combinedwithsofewerconfigurationkingdevelopmentanddesignofasuitablefactoryassemblylinejobsautomaticfillingmachineinterfacecontrolsystem,fillingmachineworkflowforreal-timemonitoring,managementandcontrolsystemoftheblock,centralizedcontrolfunctiontoachieveahigh-speedbottlingoriented,accurate,intelligent,multi-functionalanduser-friendlyinterfacerequirements.Keywords:fillingmachine,PLC,KingView.-III-目录1绪论........................................................................................................................................11.1课题研究的意义.........................................................................................................11.2全自动灌装机的发展概况.........................................................................................21.2.1国内外全自动灌装机的发展状况..................................................................21.2.2国内外全自动灌装机制造业的发展趋势......................................................21.3全自动灌装生产线.....................................................................................................41.3.1液体灌装的基本原理......................................................................................41.3.2液体灌装的方式..............................................................................................41.3.3灌装的定量方法..............................................................................................41.3.4影响灌装的因素..............................................................................................61.3.5灌装机及外围辅机的概况与种类..................................................................61.4本论文研究的主要内容.............................................................................................72可编程控制器........................................................................................................................82.1PLC发展的历史..........................................................................................................82.2可编程控制器的发展阶段及其定义.........................................................................92.2.1可编程控制器的发展阶段..............................................................................92.2.2可编程控制器的定义....................................................................................102.3PLC的特点................................................................................................................102.4可编程控制器的分类...............................................................................................132.4.1按照容量和功能分类....................................................................................132.4.2按照结构形式分类........................................................................................142.4.3按照使用情况分类........................................................................................152.5PLC的应用................................................................................................................152.6PLC的基本组成和工作原理....................................................................................162.6.1PLC的基本组成.............................................................................................162.6.2PLC的工作原理.............................................................................................203组态王及其组态王与PLC的通信......................................................................................233.1组态王简介...............................................................................................................233.2组态王软件的功能及特点......
