摘要摘要在工业生产中，有很多地方需要对粉末状或小颗粒状散状固体的流量进行准确的测量和控制，再配以给料设备组成定量给料控制系统它是集喂料、流量测量和控制于一身的设备。目前，作为许多生产设备的定量给料控制系统己广泛应用于水泥、冶金、建材、电力、化工食品、矿山、粮食等各行各业。定量给料在工业生产中发挥着越来越重要的作用，正因为其应用的广泛性，如果能提高给料系统的精度、自动化程度，就有着重要的现实意义。包装码垛自动生产线适用于石油化工、化肥、粮食、港口等行业，可对PP、PE粒子、PVC、化肥、粮食等粉状、颗粒状物料进行全自动包装码垛作业，便于用户储存、运输和销售全自动包装码垛生产线主要由自动定量包装机自动上袋机组、封口系统、倒袋机、金属检测机、重量检验机、检选机、喷墨打印机、码垛机等单元组成。通过可编程序控制器对整个生产线的工作过程进行自动控制，对运行过程中出现的故障或供料不足，供袋不及时、出垛不及时等，进行声光报警。该设备具有操作简单运行可靠，维修方便等优点。关键词：控制系统,包装码垛生产线,可编程序控制器1ABSTRACTABSTRACTIndustrialproduction,therearemanyplacesneedforpowderedorgranularsolidsflowforaccuratemeasurementandcontrol,withfeedingdeviceconsistingofquantitativefeedingcontrolsystem.Itisafeeder,flowmeasurementandcontrolinadevice.Atpresent,productionequipmentasmanyquantitativefeedingcontrolsystemhasbeenwidelyusedincement,metallurgy,buildingmaterials,electricpower,chemical,food,mining,foodandotherindustries.Quantitativefeedinginindustrialproductionisplayinganincreasinglyimportantrole,becauseofitswideapplication,ifcanimprovethefeedingsystemprecision,thedegreeofautomation,ithasimportantpracticalsignificance.Automaticbaggingpalletizinglineisusedintheindustriesofpetrochemical,fertilizer,foodprocessing,andtransportationportetc.Itcanperformbaggingandpalletizingautomaticallyforpowderandgranularmaterialssuchaschemicalfertilizer,plasticgranules(PP/PE/PVC)andgrainsetc.Itiseasyforcustomerstostore,transportandsaletheirproducts.Automaticbagging&palletizinglineconsistsofauto-weighingbaggingmachine,auto-bagfeedgroup,sealingsystem,bagturndownmachine,metaldetector,sortingmachine,jetprinterandpalletizingmachineetc.units.Throughprogrammingcontroller,thewholesystemprocesscanbeautomaticcontrolled.Anyprocessoperationtroubles,notenoughfeeds,bagfeedingnotdueorpalletizingnotintimeallcanbealarmedbysoundorlight.Ithastheadvantagesofsimpleoperation,reliableandeasymaintenanceetc.KEYWORDS:controlsystembagging,palletizingline,Programmablecontroller2目录目录摘要.........................................................1ABSTRACT...........................................................2目录.........................................................31绪论........................................................41.1引言..................................................41.2PLC概述.................................................41.3包装码垛自动生产线设计的内容........61.3.1包装码垛自动生产线的应用现状...61.3.2包装码垛自动生产线设计的要求...72包装码垛自动生产线系统组成.................82.1概述..................................................82.2包装码垛自动生产线系统组成............83包装码垛生产线控制系统硬件设计........183.1PLC控制的介绍....................................183.2PLC控制系统硬件设计..........................193.3控制系统电气原理图........................234包装码垛生产线控制系统软件设计........244.1包装码垛自动生产线工艺流程..........244.2程序控制逻辑...................................254.2.1包装部分.......
