基于PLC控制的全自动灌装机系统的设计.doc

- I- 摘要食品机械是专为食品工业提供服务的,大约有 70% 的包装机械是为食品包装提供服务的,最近几年饮料业迅速发展,市场对液体灌装设备的需求量增长迅猛。国内的包装机械起歩较晚, 而国外发达国家的包装设备已经向高效率、高精度、高自动化程度方向发展,目前虽然采用引进一消化的发展模式能满足生产需求,但技术含量不高,特别是对光、磁和计算机等先进技术的应用较少,从而使得国内与国外相比在包装机械的包装精度和运行稳定性上还是存在着较大差距的。本论文以全自动液体灌装机作为研究对象,采用欧姆龙 CMP1A 型 PLC 对其控制系统进行软件设计,并利用组态王做出监控系统,实现基于欧姆龙 PLC 与组态王的控制系统。采用模块化的设计方法,对全自动液体灌装机的主要控制要求进行程序设计,由理瓶机、灌装机、封盖机和外围辅机构成的四块控制模块,再结合组态王软件开发设计出一种适合工厂流水线化作业的全自动灌装机控制系统界面,对灌装机的工作流程实现实时监控,实现控制系统的分块管理、集中控制的功能,实现了灌装生产高速化、精确化、智能化、多功能化以及操作界面人性化的要求。关键词:灌装机、 PLC 、组态王。- II- A bstract Food Machinery is designed to provide services to the food industry, about 70% of the packaging machinery is to provide services for the food packaging, beverage industry developed rapidly in recent years, market demand for the rapid growth of liquid filling equipment. Domestic packaging machinery since late walk, and packaging equipment in developed countries has been developed toa high efficiency, high precision, high degree of automation direction, although the current model of development with the introduction ofa digestion can meet the production needs, but not high-tech, in particular the application of less light, ism and puter technology, making domestic and foreign in the pared the accuracy and stability of packaging machinery running or there isa big gap. In this paper, automatic liquid filling machine as the research object, using Omron CMP1A its type PLC control system software design and configuration king made ? ? use of monitoring systems, Omron PLC-based control system and configuration of the king. Modular design approach, the main control requirements for automatic liquid filling machine for program design, control module consists of four Unscramble, filling machine, capping machine and peripheral position, combined wi
