基于PLC废纸打包机控制系统VIP免费

摘要随着人们生活水平的提高和现代工业的迅速发展，国家对可持续发展道路的战略方针的重视，再加上目前能源紧缺，环境污染，严重的威胁到了人类。随着利用先进的自动化技术，人机界面技术和通讯技术，设计高性能，高节能，操作简易维护方便，流程简单的废纸打包机成为未来趋势，所以用PLC进行对系统进行控制是发展趋势。本论文基于全自动废纸打包机的原理，提出了PLC控制方案。通过对废纸打包机工作过程的分析，设计出了符合工作要求的梯形图程序，实现了PLC对废纸打包机工作过程的控制。本论文设计的系统具有操作简单，运动平稳性高、工作可靠的优点。关键字：PLC打包机液压系统ABSTRACTAspeople'slivingstandardsimproveandtherapiddevelopmentofmodernindustry,thestateoftheroadofsustainabledevelopmentstrategicpolicyattention,coupledwiththecurrentenergyshortage,environmentalpollution,aseriousthreattothehumanrace.Withtheuseofadvancedautomationtechnology,human-machineinterfaceandcommunicationtechnologies,designinghigh-performance,high-energy,simpleoperation,easymaintenance,simpleprocessofwastepaperbalerbecomethefuturetrend,sowiththePLCtocontrolthesystemisdevelopedtrends.ThisthesisisbasedontheprincipleofautomaticwastepaperbalerproposedPLCcontrolprogram.Throughthepaperbalersworkprocessanalysis,designaladderprogrammeetthejobrequirements,therealizationofthePLCworkonpaperbalersprocesscontrol.Inthisthesis,thedesignofthesystemissimple,smoothmotionishigh,workreliable.Keywords:PLC；strappingmachine；Hydraulicsystem目录摘要.................................................................................................................................IABSTRACT..................................................................................................................II第1章绪论.................................................................................................................11.1可编程控制器在打包机中的应用概述...............................................................11.2发展现状及发展趋势...........................................................................................11.3研究目的及意义...................................................................................................31.4研究的主要内容...................................................................................................3第2章废纸打包机结构及工作原理..........................................................................52.1全自动废纸打包机的液压系统..........................................................................52.2全自动液压废纸打包机结构...............................................................................72.3全自动液压废纸打包机的工作过程...................................................................7第3章废纸打包机控制系统硬件设计.......................................................................93.1废纸打包机电气主电路.......................................................................................93.2控制电路设计...................................................................................................11第4章废纸打包机控制系统软件设计.....................................................................154.1三菱FX2N控制器性能，及其设计方法........................................................154.2系统初始化.........................................................................................................174.4打包机自动控制..................................................
