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、台布和窗帘等的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烫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。可编程控制器（PLC）（PLC）ABSTRACT With the development of society, as well as the specialization of the division of labor in society, there are more and more groups such as hotel, school and factory and so on that give the clothing liking sheet, towel, tablecloth and curtain and so on to the washing factory to clear and ironing. As one of the automatic devices, folding machine folds the cleared-and-ironed clothing automatically, solving the artificial- folded problems such as time-consuming, poor quality and direct-operation, etc. Programmable logic controller (PLC) is usually applied to electric control system because its simplicity, reliability, flexibility and strong functions. In this paper, we introduce the electric control system of folding machine, using the technology of PLC, transducer and touch panel. This paper can be summarized as follows: (1) Briefly introduce the mechanical drive parts, including the calculation of shaft and belt, and the chose of motor and break/clutch union. (2) Introduce the main hardware of the electric control system of the folding machine including PLC, transducer, touch panel, sensor and other electric parts. (3) Give the flow chart of the electric control system, the I/O and other soft element of the PLC, the program, the design of touch panel and the communication of PLC. Keywords：folding machine; Programmable logic controller(PLC); Mitsubishi 目 录 1 绪论 5 1.1 课题选择背景和意义 5 1.2 国内外研究现状 5 1.3 本文主要研究内容 7 2 总体设计 9 2.1自动折叠机的性能结构分析 9 2.1.1自动折叠机的工作原理 9 2.1.2折叠机的主要参数 10 2.1.3折叠机的误操作原理分析及改正方法 10 2.2折叠机电气控制总体系统设计方案 11 2.2.1系统功能设计 11 2.2.2系统总体结构设计方案 11 2.3折叠机的主要控制方式 12 2.3.1继电器控制技术 12 2.3.2交流变频变压控制技术 12 3 控制系统硬件设计 14 3.1传感器选型及其安装 14 3.1.1光电传感器选型及其安装 14 3.1.2旋转编码器的选型及安装 17 3.2变频器的选择 19 3.2.1变频器的基本构成 20 3.2.2变频器的分类 20 3.2.3变频器变频原理 21 3.2.4变频器品牌型号与规格的选择 22 3.3.5 选择的变频器应满足的条件 23 3.3.6 通用变频器概况 23 3.3.7 安川VS—616G5型通用
