南京工程学院毕业设计说明书论文作者王璐学号233070110系部工程基础实验与训练中心专业自动化(系统集成)题目基于台达PLC的立体库控制系统设计指导者程啟华讲师评阅者2011年06月南京南京工程学院毕业设计说明书(论文)GraduationDesign(Thesis)AutomatedLibrarySystemControlBasedondetalPLCBYWANGLuSupervisedbyLecturerCHENGQihuaDepartmemtoftheBASISofEXPERIMENTSandTRAININGCENTERNanjingInstituteofTechnologyJune,2011南京工程学院毕业设计说明书(论文)摘要自动化立体库是一种集信息,存储管理于一体的高技术密集型机电一体化产品,是一种多层次存放货物的高架仓库系统。它是把计算机与信息管理和设备控制集合起来,能按控制指令要求自动完成货物存取的要求。本文的设计思路是将整个立体库的区域虚拟的分为三个区,区域划分是基于物料属性信息之上的,本课题有三种物料,即高成品件、低黑件、低白件。根据物料属性信息分别将其放入相应的货位,以提高存取的工作效率。因PLC强大的控制功能,本控制系统的控制器采用PLC控制,堆垛机由两轴(X/Z)伺服定位轴机构组成,具有三自由度。堆垛机是自动化立体库中的重要设备,它能够在自动化立体库的货架间来回穿梭运行,将货物放入货架或者相反取出货架上的货物。输送带由变频器控制,可以进行变频传输。采用光电传感器检测有无物料,变频传输物料,分析堆垛机的工作过程,并确定堆垛机的定位方案。通过计算机系统对PLC的运行监控,并对货架信息进行处理,解决了堆垛机存取货物路径的优化问题。最终由PLC对堆垛机系统进行控制。人机界面,是系统和用户之间进行交互和信息交换的媒介,它实现信息的内部形式与人类可以接受形式之间的转换。人机界面可以对现场设备进行监控,及时采集系统信息,发现并处理故障,保证系统良好的运行,是自动化生产的必然发展方向。关键词自动化立体库堆垛机PLC人机界面南京工程学院毕业设计说明书(论文)ABSTRACTAutomatedlibraryisacollectionofinformation,storagemanagementinoneofthehightechintensivemechanicalandelectricalintegrationproducts,isamultilevelstorageofgoods,overheadstoragesystem.Itisthecomputerandinformationmanagementandcontrolequipmenttogetherandfollowtheinstructionstoautomaticallycontroltheaccessrequirementsofthegoods.Thisdesignideaistheareatheentirethreedimensionalvirtuallibraryisdividedintothreezones,zoningisbaseduponthematerialpropertyinformation,thesubjectofthreematerials,namelyhighfinishedparts,lowblackpieces,lowwhitepieces.,Respectively,accordingtothematerialattributeinformationintotheappropriatestockofitsposition,inordertoimproveaccessefficiency.PLCcontrolforthepowerful,thecontrollerusesthecontrolsystemPLCcontrol,stackingmachineconsistsoftwoaxesX/Zaxisservopositioninginstitutions,withthreedegreesoffreedom.Automatedstackingmachineisanimportantequipmentinthelibrary,itcanautomatedlibraryshelvesinthebackandforthbetweenrunningintothecargoshelforviceversaoutthegoodsontheshelves.Controlledbythedrivebeltandcanbefrequencytransmission.Photoelectricsensordetectswhetherthematerialsused,frequencytransmissionofmaterials,analysisoftheworkingprocessstackerandstackerpositiontodeterminetheprogram.ThroughthecomputersystemtomonitortheoperationofPLC,andtheshelfinformationprocessingtosolvetheaccessofgoodsstackerpathoptimizationproblem.UltimatelybythePLCcontrolsystemonthestacker.Manmachineinterface,thesystemanduserinteractionandinformationexchangebetweenthemedia,whichimplementstheinformationwithintheacceptableformsofthehumanformofconversionbetween.Manmachineinterfacefielddevicescanbemonitoredandtimelyinformationcollectionsystemtoidentifyanddealwithfailuretoensurethesystemisrunningwell,istheinevitabledevelopmentofautomatedproduction.南京工程学院毕业设计说明书(论文)KeywordsautomatedlibrarystackingmachinePLCcomputer南京工程学院毕业设计说明书(论文)目录第一章绪论.........................................1引言................................................................................................................................11.1本课题的目的和意义..................................................................................................11.2自动化立体库的概述..................................................................................................21.2.1自动化立体库的组成......................................................................................21.2.2自动化立体库的优点......................................................................................21.2.3自动化立体库的分类......................................................................................31.3国内外研究现状........................................................................................................31.4本课题的研究内容....................................................................................................5第二章系统控制方案的设计..............................62.1出入库原则概述.........................................................................................................62.1.1先入先出原则.................................................................................................62.1.2分区原则........................................................................................................72.1.3均布原则........................................................................................................72.1.4重力原则........................................................................................................72.1.5效率原则........................................................................................................82.1.6出入库流程的设计..........................................................................................82.2系统设计的基本步骤................................................................................................102.3系统的控制方案........................................................................................................8第三章系统的硬件设计................................123.1PLC选型..................................................................................................................123.1.1PLC的选型...............................................................................................
