【摘要】：改革开放以来,我国的经济社会快速发展,工业化水平显著提高。近30年来,我国的包装行业借助国家的政策也是飞速发展,然而由于一直采用粗放型的发展方式,我国的包装生产线自动化程度还非常的低,许多包装机械、包装设备的技术精度跟国外相比还是有很大的差距,甚至还有很多包装产品还是手工生产。为了提高效率和节约成本,各包装企业急需进行转型升级,实现包装产品的自动化生产。本文针对合作企业包装袋生产线的具体情况,在分析了该企业的生产工艺流程及产能需求后,进行了大量的试验及论证,在结构上提出了双工位的送袋方式。控制系统采用了欧姆龙CP1H型号的PLC,综合使用了伺服驱动技术、步进驱动技术、变频控制技术和现代传感技术等知识实现了套内膜包装袋的高速自动化生产。该生产线经过第二次设计升级,其速度和可靠性都得到了显著提升。套内膜包装袋自动成型机是集检测技术、机械设计、气动技术、电力拖动和实时控制于一体的自动包装流水线。整条生产线由多个机构组成,每个机构负责一道工序,各部分分工协作,共同完成复合包装袋的自动套袋和缝纫过程。本文根据包装袋的生产工艺及流程主要作了以下几个方面的设计和研究:1.研究了套袋机自动化生产线的整体机械结构的设计。2.设计了气动和真空系统,讲述了气动回路的组成及真空系统的功能。3.依据机械结构设计了系统控制部分。该控制系统为塞缝机自动化生产线的核心部分。4.研究了系统的整体硬件结构,讲述了可编程控制器的基础知识,介绍了元器件的选型及整体的控制逻辑程序。详细介绍了步进驱动、伺服驱动、变频控制的开发设计。5.设计了PLC的控制软件及上位机系统,实现了PLC与上位机的实时交互,为用户对自动化生产线实施监控提供了平台。人机交流画面是组成系统设计的关键部分,使用触摸屏可以控制套袋子的参数,实时信息,报警信息等方面的内容。6.最后对全文进行了总结,并提出了未来的展望。
[Abstract]:Since the reform and opening up, China's economy and society have developed rapidly, and the level of industrialization has improved significantly. In the past 30 years, the packaging industry in our country has also developed rapidly with the aid of national policies. However, due to the extensive mode of development, The degree of automation of packaging production lines in China is still very low. The technical accuracy of many packaging machinery and packaging equipment is still far behind that of foreign countries. In order to improve efficiency and save cost, packaging enterprises urgently need to transform and upgrade to realize the automatic production of packaging products. After analyzing the production process and production capacity demand of the enterprise, a large number of tests and demonstration were carried out, and a double station bag feeding method was put forward in the structure. The control system adopted the CP1H model of OMRON and the servo drive technology was used synthetically. The knowledge of stepper drive technology, frequency conversion control technology and modern sensing technology has realized the high speed automatic production of the inner packing bag. The production line has been upgraded after the second design. Its speed and reliability have been greatly improved. The automatic molding machine for inner packaging bags is a set of testing technology, mechanical design, pneumatic technology, Pipeline, the whole production line is composed of multiple organizations, each of which is responsible for a working procedure, and each part of the production line is divided into two parts. The automatic bagging and sewing process of the composite bag is completed together. According to the production technology and process of the packaging bag, the design and research of the following aspects are made in this paper. 1. The integral mechanical connection of the automatic bagging machine production line is studied. The pneumatic and vacuum systems are designed, The composition of pneumatic loop and the function of vacuum system. 3. The control part of the system is designed according to the mechanical structure. The control system is the core part of the automatic production line of stitch machine. The whole hardware structure of the system is studied. This paper describes the basic knowledge of the programmable controller, introduces the selection of components and the whole control logic program, and introduces the development and design of step drive, servo drive and frequency conversion control in detail. The control software of PLC and the upper computer system are designed. The real-time interaction between PLC and the host computer is realized, which provides a platform for users to monitor and control the automatic production line. The man-machine communication screen is the key part of the system design, and the parameters and real-time information of the bag can be controlled by the touch screen. Finally, the paper summarizes the full text and puts forward the future prospect.
