自动加工单元之卸垛机的设计摘要传统的机械设备与产品，多是以机械为主，是电气、液压或气动控制的机械设备。随着工业水平的不断发展，机械设备已逐步地由手动操作改为自动控制，设备本身也发展成为机电一体化的综合体。目前，可编程序控制器已成为工业自动化领域中最重要、应用最多的控制装置，居工业生产自动化三大支柱(可编程序控制器、机器人、计算机辅助设计与制造)的首位。其广泛的深度和广度成为衡量一个国家工业自动化程度高低的标志。本文首先概述了PLC的产生、发展及应用现状，随后又论述了自动生产线的历史、我国的应用现状及存在的一系列问题及今后该领域的发展趋势。其次进行了系统控制部分的设计。该系统的核心部分是卸垛自动生产线的控制系统。在该部分中，介绍了PLC的綦础知识；详细介绍了工艺流程及控制逻辑；设计了PLC控制系统软件和硬件；并介绍了PLC上位连接系统，为用户对卸垛自动生产线实现实时监控、远程诊断和网络化管理搭建了平台。关键词卸垛；控制系统；PLCDestackingAutomaticproductionLineandControlSystemAbstractMorethanthetraditionalmechanicalequipmentandproducts,mainlyonmechanical,electrical,hydraulicorpneumaticcontrolisthemechanicalequipment.Withthecontinuousdevelopmentofindustriallevel,mechanicalequipmenthasbeengraduallyfrommanualtoautomaticcontrol,thedeviceitselfalsodevelopedintoacomplexofelectromechanicalintegration.Atpresent,theprogrammablecontrollerhasbecomethemostimportantandmostusedinindustrialautomationcontrolequipment,thethreepillarsofindustrialproductionautomation,programmablecontroller,robot,computeraideddesignandmanufacturing)ofthefirst.Itsdepthandwidthofthebroadmeasurebecomeathesymbolofindustrialautomationlevelofthecountry.Atfirst,thispapersummarizedpresentconditionsoftheformation,developmentandapplicationofPLC,thendiscussestheapplicationofautomaticproductionlineofhistory,andaseriesofproblemsandthefuturetrendofthedevelopmentofthisfield.Secondlythispapergivesthedesignofthesystemcontrolpart.Thesystemisthecorepartofthedestackingautomaticproductionlinecontrolsystem.Inthispart,thepaperintroducesthePLCregarddevelopmentknowledge;Introducedthetechnologicalprocessandcontrollogic.Keywords：destacking;Controlsystem;PLC目录1绪论..............................................................12卸垛自动生产线总体设计方案........................................22.1概述............................................................22.2系统组成........................................................22.3系统功能........................................................32.4本章小结........................................................33卸垛自动生产线机械系统及电气系统设计..............................43.1概述............................................................43.2设备电气配置....................................................53.2.1减速机设置....................................................53.2.2光电开关、接近开关设置：......................................63.2.3控制气缸的阀及磁性开关：......................................93.3电气控制要求：.................................................113.4安全要求：.....................................................153.5、走线要求：....................................................164气动及真空系统...................................................174.1气动系统的组成.................................................184.2气动回路设计...................................................184.3本章小结.......................................................195卸垛自动生产线PLC.....
