摘要本文阐述了可编程控制器(以下简称PLC)从产生到现在,实现了接线逻辑到存储逻辑的飞跃;。其功能从弱到强,实现了逻辑控制到数字控制的进步。随着科技的是新月异的飞速发展,社会经济的发展步伐需要不断加快,更加需要现代化工业的不断进步。一系列自动化生产设备便出现在生产车间,提高了生产效率,提高了经济效益,带动了整个社会经济发展,故在此开展了“罐装机系统设计”的课题。下面介绍该系统设计的内容。文中所述的PLC程序设计已经过多次的实验。按其生产步骤、稳定性等方面,所设计的PLC程序已验证其正确性了。该系统充分利用了学习中的可编程控制器(PLC)的多方面知识和方法,。本设计作为毕业设计题目,主要价值在于运用理论与实际相结合,虽然没有百分百的实现,但也不失这样的价值。如前所述,全球都需要高新科技,来带动整个经济的发展。自动罐装机是自动化生产技术的代表之一是必不可少的。这一控制系统的实现和应用,充分体现了PLC系统在工业的现场的应用,以及根于设计和不同的需求改变数据和状态,还可以使其应用的范围更加广泛,总之PLC在工业生产上起着很大的作用关键词:罐装机系统、可编程控制器(PLC)、程序设计、梯形图ABSTRACTThepaperitsdescribedesignprojectofthepurewaterautomaticcan,systemitsmainlydesignsforautomaticsystemoftheproductline.Followingtheprinciplethatthetheorycombineswiththepractice,baseontheprincipleofthethreadofPLCcontrolling,onthepremiseofeasuringandprogramthedesign,recommendeveryprojectofsystematicdesignprocessofwholeautomaticcantorealizefromthesuperficialtothedeep.Withthescienceandthetechnologydevelopingatfullspeedofcrescent,improveproductionefficiency,haveincreaseeconomicefficiency,havedriventhewholesocialeconomicdevelopment.Solaunchedthesubjectthat"thedesignedofAutomaticCanSystem".Nowcontentthattheintroductionshouldbedesignedsystematically.Thefulltextisdividedintosevenchapters.ChapterIdescribesthescopeandapplicationoftheautomaticcannedfunctionalsignificance.ChapterIIIdescribedthePlccontrolsystemdesignofthebasicprinciples,maincontents,thegeneralstepsChapterIVonthemainpowerlinestotheprinciplesofthecomponents,characteristicsandparametersandpurchase.thedesign,Plcinstructionstable.profiles.Originallydesignasthegraduationprojecttopic,chiefvalueliesinusingthetheorytocombinewithreality,thoughthereisno100%realization,doesnotlosesuchvalueeither.Asnotedpreviously,thewholeworldneedsnewandhightechnology,todrivethedevelopmentofthewholeeconomy.Automaticcanautomaticrepresentativeofproductiontechnologyoneofessential,itplaysaroleinholdingthebalanceinindustrialproduction.Keywords:AutomaticCanSystemThePLCcontrolProgramdesignLadder-shapeddiagram目录第一章引言............................................................................................................................................................1第二章灌装机传动系统设计................................................................................................................................22.1工作原理及工艺动作过程简介................................................................................................................22.2原始数据及设计要求:............................................................................................................................22.3工作原理和工艺动作分解........................................................................................................................22.3.1工作原理图...........................................................................................................................
