同时本文还对系统的结构，硬件配置， 触摸屏设置软件应用进行了阐述关键词：自动打钉机，PLC，控制系统设计，自动化加工The Design of Automatic Nailing Machine Control SystemABSTRACTAutomatic nailing machine is a box of mass production of wooden pallets a mechatronics equipment, involving mechanical, electrical, control, hydraulic and pneumatic and other technology. The task of this project is to study the design of the electrical control system to automate the job of nailing nailing machine according to the principle of automatic nailing machine.In this thesis, complete the following tasks: the first collection and analysis wooden pallet automatically to fight nail machine's works, the development of its control system program; subsequently carried wooden pallet automatically to fight nail machine's basic structure design, including nailing institutions and feeding agencies; thencontrol system program, to complete the selection of a variety of devices and components, verification, design of system hardware circuit design, circuit schematic of the design of control systems, and low-voltage electrical cables (power, control, communications) and the control cabinet unitlearning and understanding of the use of a variety of low-voltage electrical and control theory; Second, it introduces the basic components of a PLC (programmable program controller), the working principle, the main features; above the practical application of knowledge and on-site to make the overallprogram, control strategies, as well as hardware configuration and software implementation. Which also charted a variety of low voltage electrical, servo motors, touch screen and each function module wiring circuit. Analysis and the use of PLC programming method, the principle of motor speed and a variety of various low voltage commonly used electrical components. Reasonable Through research and analysis to determine the system, according to the system function to select a series of Siemens (PLC) products, combined with the product and its programming features of the development of software for automatic control. The same time, the structure of the system, hardware configuration, the touch screen to set the software application described.KEYWORDS:automatic nailing machine，PLC，control system design，automatic processing / 目 录摘要………………………………………………………………………………………IABSTRACT…………………………………………………………………………………II1概述……………………………………………………………………………………11.1课题背景资料……………………………………………………………………11.1.1木托盘资料………………………………………………………………11.1.2托盘分类…………………………………………………………………11.1.3木托盘加工…………………………………………………………………21.2自动打钉机控制系统介绍…………………………………………………………31.3课题设计目标………………………………………………………………………32打钉机控制系统的总体方案………………………………………………………………42.1自动打钉机工作原理………………………………………………………………42.1.1工作示意图…………………………………………………………………42.1.2本机主要组成部分…………………………………………………………52.1.3控制系统的组成……………………………………………………………62.2控制总体方案………………………………………………………………………62.3控制原理………………………………………………………………………72.3.1自动模式……………………………………………………………………72.3.2手动模式……………………………………………………………………83控制系统硬件部分设计…………………………………………………………………93.1电气控制系统组成…………………………………………………………………93.1.1控制线路设计………………………………………………………………93.1.2控制线路图与说明…………………………………………………………93.2电器元件列表………………………………………………………………………113.3主要电器元件计算与选型…………………………………………………………123.3.1断路器………………………………………………………………………123.3.2接触器………………………………………………………………………133.3.3开关电源……………………………………………………………………143.3.4控制变压器…………………………………………………………………153.3.5指示灯………………………………………………………………………153.3.6主令电器……………………………………………………………………153.3.7继电器………………………………………………………………………163.3.8变频器………………………………………………………………………163.3.9电动机………………………………………………………………………173.3.10熔断器……………………………………………………………………173.4 PLC选型………………………………………………………………………183.4.1 PLC的分类………………………………………………………………183.4.2 PLC选型…………………………………………………………………194 控制程序设计………………………………………………………………………214.1程序流程图………………………………………………………………………214.2程序梯形图………………………………………………………………………224.2.1初始化部分…………………………………………………………………224.2.2漏钉检测部分………………………………………………………………234.2.3切换部分……………………………………………………………………244.2.4手动操作部分………………………………………………………………244.2.5自动操作部分………………………………………………………………254.2.6主设备操作部分……………………………………………………………254.2.7报警部分……………………………………………………………………265 触摸屏设计………………………………………………………………………………275.1触摸屏选型…………………………………………………………………………275.2本设计中触摸屏程序设计…………………………………………………………275.2.1触摸屏组态软件装…………………………………………………………275.2.2触摸屏组态软件界面设计…………………………………………………285.2.3离线仿真……………………………………………………………………326 总结………………………………………………………………………………………33致……………………………………………………………………。
