****大学毕业设计I摘要随着社会的进步,社会分工不断加细,越来越多的酒店,学校,工厂等事业单位把被单,毛巾,台布和窗帘等布草送给专业的洗涤厂来洗烫。折叠机作为洗涤厂的自动化设备之一,自动完成对各种洗好并且熨平的布草的折叠工作,解决了人工折叠布草时间长,质量差和不可以流水作业等问题。可编程的控制器(PLC)作为替代继电器的新型控装置,简单可靠,操作方便,通用灵活,体积小,使用寿命长且功能强大,容易使用,可靠性高,被大量用于自动化电气控制系统中。本文介绍了一种基于可编程控制器(PLC),结合变频器,触摸屏等技术的折叠机电气控制系统。主要内容包括以下几个方面:(1)折叠机机械传动部分的计算,包括了轴,皮带的计算和校核,电机、制动/离合器的选型。(2)介绍折叠机电气控制系统所需要的硬件,包括PLC、变频器、人机交互界面设备、传感器及其他的电子器件。(3)描述了控制系统流程图、PLC的I/O分配及其他软件的功能、PLC程序的设计、人及交互界面设计及PLC通讯程序设计。关键词:折叠机;可编程控制器;人机交互;三菱****大学毕业设计IIABSTRACTWiththedevelopmentofsociety,aswellasthespecializationofthedivisionoflaborinsociety,therearemoreandmoregroupssuchashotel,schoolandfactoryandsoonthatgivetheclothinglikingsheet,towel,tableclothandcurtainandsoontothewashingfactorytoclearandironing.Asoneoftheautomaticdevices,foldingmachinefoldsthecleared-and-ironedclothingautomatically,solvingtheartificial-foldedproblemssuchastime-consuming,poorqualityanddirect-operation,etc.Programmablelogiccontroller(PLC)isusuallyappliedtoelectriccontrolsystembecauseitssimplicity,reliability,flexibilityandstrongfunctions.Inthispaper,weintroducetheelectriccontrolsystemoffoldingmachine,usingthetechnologyofPLC,transducerandtouchpanel.Thispapercanbesummarizedasfollows:(1)Brieflyintroducethemechanicaldriveparts,includingthecalculationofshaftandbelt,andthechoseofmotorandbreak/clutchunion.(2)IntroducethemainhardwareoftheelectriccontrolsystemofthefoldingmachineincludingPLC,transducer,touchpanel,sensorandotherelectricandotherelectricparts.(3)Givetheflowchartoftheelectriccontrolsystem,theI/OandothersoftelementofthePLC,theprogram,thedesignoftouchpanelandthecommunicationofPLC.Keyword:foldingmachine;Programmablelogiccontroller(PLC);Humancomputerinteraction;Mitsubishi****大学毕业设计I目录摘要............................................................................................................IABSTRACT.................................................................................................II前言............................................................................................................1第1章绪论..................................................................................................21.1国内外研究现状..............................................................................................21.2本文主要研究内容..........................................................................................4第2章总体设计...........................................................................................62.1自动折叠机的性能结构分析...........................................................................62.1.1自动折叠机的工作原理.........................................................................62.1.2折叠机的主要参数.................................................................................72.1.3折叠机的误操作原理分析及改正方法.................................................72.2折叠机电气控制总体系统设计方案...............................................................82.2.1系统功能设计.........................................................................................82.2.2系统总体结构设计方案.........................................................................82.3折叠机的主要控制方式...................................................................................92.3.1继电器控制技术.....................................................................................92.3.2交流变频变压控制技术.......................................................................10第3章控制系统硬件设计...........................................................................113.1传感器选型及其安装.....................................................................................113.1.1光电传感器选型及其安装...................................................................113.1.2旋转编码器的选型及安装...................................................................153.2变频器的选择.................................................................................................173.2.1变频器的基本构成...............................................................................173.2.2变频器的分类.......................................................................................183.2.3变频器变频原理...................................................................................183.2.4变频器品牌型号与规格的选择...........................................................203.2.5选择的变频器应满足的条件..............................................................203.2.6通用变频器概况..................................................................................213.2.7安川VS—616G5型通用变频器..........................................................223.2.8变频器参数的设置..............................................................................243.2.9变频器容量和制动电阻参数的计算..................................................253.3PLC简介及选择............................................................................................25****大学毕业设计II3.3.1PLC简介...............................................................................................253.3.2可编程控制器(PLC)的选型.............................................................293.4控制系统人机交互设备的选择....................................................................303.5静电消除器........
