基于PLC的全自动包装码垛生产线控制系统设计

摘要

传统的机械设备与产品，多是以机械为主，是电气、液压或气动控制的机械设备。随着工业水平的不断发展，机械设备己逐步地由手动操作改为自动控制，设备本身也发隐形茶杯展成为机电一体化的综合体。可融合拼接编程控制器(PLC)是以微处理器为核心，综合计算机技术、自动化技术和通信技术发展起来的一种新型工业自动控制装置。经过30多年的发展，目前，可编程控制器已成为工业自动超细铜粉化领域中最重要、应用最多的控制装置，己跃居工业生产自动化四大支柱(可编程控器、数控机床、机器人、计水浴式汽化器算机辅助设计与制造)的首位。其应用的深度和广度已成为衡量一个国家工业先进与自动化程度高低的标志。

本论文共分四章，从可编程控器(PLC)基础到整个系统的规划设计，以及PLC控制系统的硬件、软码垛件的开发，给出全面、详细的设计思路。该系统的核心部分是包装码垛自动生产线的控制系统，其控制系统主要是以可编程控制器(PLC)为基础进行集成控制的。

全自动包装码垛生产线主要应用于化工、粮食、食品及医药等行业中的粉、粒、块状物料（如塑料、化肥、合成橡胶、粮食等）的全自动包装，即对包装过程中的称重、供袋、装袋、折边、封袋、倒袋整形、批号打印、检测、转位编组高纯球形硅微粉、码垛、托盘和垛盘的输送等作业

全部实现自动化。以PLC为基础的全自动包装码垛生产线，控制系统简单、便于维护、适应性强，自动化程度高，节约人力，可极大提高生产效率。

Abstract

The traditional mechanical device and the product, many are by the machinery primarily, is electrical, the hydraulic pressure or the pneumatic control mechanical device. Along with the industry level's unceasing development, mechanical device oneself changes the automatic control gradually by the manual operation, the equipment itself also develops into the integration of machinery complex compound. Programmable controller (PLC) is take the microprocessor as a core, the comprehensive computer technology, the automated technology and the communication develop one new industry automatic control device. After more than 30 years development, at present, the programmable controller has become in the industrial automation domain to be most important, to apply most control devices, oneself leaps to the industrial production automation four big props

(programmable controller, numerically-controlled machine tool, robot, computer-aided design and manufacture) the first place. Its application's depth and the breadth have become weigh a national industry to be advanced and automaticity height symbol.

This thesis consists of four chapters, from the programmable logic controller (PLC) based planning and design of the entire system, and PLC control system hardware, software development, give full and detailed design ideas. The core of the system is Palletizing automatic production line control system, the control system is mainly based on programmable logic controller (PLC) as the basis for integrated control.

Automatic Palletizing production line is mainly used in chemical, food, food and pharmaceutical industries in the flour, grain, bulk materials (such as plastics, fertilizers, synthetic rubber, food, etc.) of the automatic packaging, ie packaging process weight for bags, bagging, folding, envelope, plastic bags down, batch printing, testing, transfer grouping, stacking, pallets, and stack operations such as disk full automated transmission. With PLC based fully automatic palletizing packaging production line, contr

ol system is simple, easy maintenance, strong adaptability, high automation, saving manpower, can greatly increase productivity.
