目的为了提高包装生产线的自动化程度,以袋式包装生产线为研究对象,结合工控机、运动控制卡、PLC设计一种控制系统。方法袋式包装生产线的主要结构包括封合切分、喷墨打码、放袋、定量下料等装置,以工控机为核心,搭建相应的控制系统,整合生产线内各驱动器、传感器,使其具有数据处理、信号监控、轨迹规划等功能。同时给出软件设计方法,基于遗传算法讨论系统平衡问题,并进行试验验证。结果基于所述控制系统的包装生产线可靠性较高,合格率达到99.9%。结论该包装生产线控制系统能够满足自动化生产需求。

The work aims to design a control system in combination with industrial personal computer, motion control card and PLC, with bag packaging production line as research object, so as to improve the automation degree of packaging production line. The main structure of bag packaging production line included many devices, such as sealing segmentation, inkjet printing, bag-putting, quantitative dumping and so on. With industrial personal computer as the core, the corresponding control system was built, and the drivers and sensors in the production line were integrated, so that it had the functions like data processing, signal monitoring and trajectory planning. The software design method was also given. Finally, the system equilibrium problem was discussed based on genetic algorithm and the test verification was carried out. The packaging production line based on the described control system was of high reliability and its qualification rate was 99.9%. It is concluded that the control system of such packaging production line can meet the demand of automatic production.
