基于PLC的砌块成型机的电气系统设计.docVIP

内容提要 砌块砖成型机是墙砖压制成型的关键设备。为了克服传统的继电器、接触器控制手段接线复杂，机械触点多，可靠性低的局限性，通过采用可编程序控制器(PLC)予以克服和弥补。本文介绍了砌块成型机的结构及其液压系统模型，设计出了它的电气原理图、操作控制面板,对元器件进行了选型，利用变频器对输送带进行传动速度控制，并实现系统故障报警。PLC选用日本三菱公司FX2N系列，设计出了系统程序框图，顺序功能图以及梯形图。经过检测和实验室的模拟调试，结果较为理想，均已达到各项设计要求，充分证明了该砌块成型机控制方案的正确性和可行性。 Summary The artificial brick shaper is the essential equipment which the wall brick suppresses takes shape. but its control section still used the traditional control method of Relays and ntactors caused the wiring complex and the mechanical electronic contact many. These limitations may use the programmable foreword controller (PLC) to overcome and to make up. The design is given a set of artificial brick shaper of the structure and its hydraulic system model. designed its Electrical schematic diagram、 peration control panel and The selection of components. This design selects Japan Mitsubishi Corporation FX2N ries PLC to carry on the control. Designed the system of Process diagram 、Sequential Function chart and the trapezoidal chart. Used inverter to drive on the conveyor belt speed control and achieved the breakdown reports to the police procedure. The result of system debugging experiment is ideal, which has met each design requirements and fully proven accuracy and the feasibility of this dyeing machine control plan. 目 录 内容提要．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．Ⅰ Summary．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．Ⅱ 绪 论．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．1 1 砌块成型机的结构和液压控制系统．．．．．．．．．．．．．．．．．．．．．．．．．．．2 1.1 砌块成型机的结构组成及功能．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．2 1.2砌块成型机的液压控制原理．．．．．．．．．．．．．．．．．．．．．．．．．．．．．3 2 砌块成型机电气系统设计方案的选择．．．．．．．．．．．．．．．．．．．．．．．．．．．．5 3 砌块成型机电气系统设计具体过程．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．8 3.1 砌块成型机电气控制系统设计的电气设计概况．．．．．．．．．．．．．．．．．．．8 3.2 砌块成型机电气控制系统电气原理图的设计．．．．．．．．．．．．．．．．．．．．．9 3.3 电气元件选型．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．13 3.4 PLC程序设计．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．．30 3.5 操作面板布置设计．．．．．．．．．．．．．．．．．．．．．．．．．．．．
