【摘要】：随着人民生活水平的提高,人们对休闲饮品的需求也飞速增加,同时刺激着饮料工业迅速发展,带动着液体灌装设备的需求大量增长。依据我国统计局的统计数据,由2000年开始,截止至2011年,11年间中国饮品行业总产量已经由0.15亿吨飞速增长到1.2亿吨,年平均增长率达到近二十一个百分点。国内的包装机械起步不早,且技术含量较低,仅能满足一般生产需求；而且对像光、磁和计算机等一些先进技术的利用很少。这样我国的包装机械的性能就同国外有着一定差距。早期的灌装生产线的电气设备控制系统采用的继电器加接触器控制模式,使用过程灌装速度较慢,不够稳定,经常出现问题；出现故障时,人们总是凭借经验进行排查,同时在饮品生产过程当中经常发生二次污染,导致产品合格率低,降低了企业的生产效益。本文针对灌装生产线的全自动控制系统进行研究,整个灌装过程使用可编程控制器(Programmable Logic Controller, PLC)进行控制,提高了灌装精度和运行稳定性,并且使生产线集清洗、灌装、加盖一体化,具有无瓶不灌装、无瓶不加盖、自动供盖、过载保护等多种功能,缺瓶不灌装与不加盖动作完成率可达100%。每个封盖头的工作速度可达2000瓶/小时,灌装容量误差小于0.4%。本文首先对灌装机做了基础性研究,并在此基础上分析其灌装的工艺流程,在熟悉工艺的条件下对灌装机进行控制系统方案设计；然后,根据设计方案对灌装机设备制造过程中所需要的元器件进行了选型,在该设备中,PLC是核心模块,主要是对PLC进行选型和模块定义；最后,对灌装机设备的控制中心的嵌入式软件进行了分析和设计,通过程序的控制,并设计了人机交互界面,方便用户的操作使用,在对人机交互界面设计的时候,采用的是PLC与控制屏联合作用的方式,实现灌装机设备的自动化操作和科学化管理。
[Abstract]:With the improvement of people's living standard, people's demand for leisure drinks is also increasing rapidly. At the same time, it stimulates the rapid development of beverage industry and leads to a large increase in the demand for liquid filling equipment. According to the statistics data of China's Bureau of Statistics, from 2000 to 2011, the total production of beverage industry in China has increased rapidly from 15 million tons to 120 million tons, with an annual average growth rate of nearly 21 percentage points. The domestic packaging machinery starts late and has a low technology content, which can only meet the general production needs, and the use of some advanced technologies such as light, magnetism and computer is rare. In this way, the performance of packaging machinery in China and abroad has a certain gap. The relay and contactor control mode used in the electrical equipment control system of the early filling production line, the filling speed is slow, the filling speed is not stable, and problems often occur. At the same time, secondary pollution often occurs in the process of beverage production, which leads to the low qualified rate of products and reduces the production efficiency of enterprises. In this paper, the automatic control system of filling production line is studied. The whole filling process is controlled by Programmable Logic Controller, PLC), which improves the filling precision and operation stability, and makes the production line gather, clean and fill. It has many functions, such as no bottle filling, automatic supply cover, overload protection and so on. The complete rate of the action without bottle filling and without capping can reach 100%. The working speed of each sealing head can reach 2000 bottles / hour, and the error of filling capacity is less than 0.4. In this paper, the basic research on the filling machine is done, and on the basis of this, the filling process is analyzed, and the control system scheme of the filling machine is designed under familiar technological conditions. According to the design scheme, the components needed in the manufacturing process of the filling machine are selected. In the equipment, the PLC is the core module, which is mainly the type selection and module definition of the PLC. The embedded software of the control center of the filling machine equipment is analyzed and designed. Through the control of the program, the man-machine interactive interface is designed, which is convenient for the user to operate and use. The automatic operation and scientific management of filling machine equipment are realized by the way of combined action of PLC and control screen.
