基于Petri网的高速机器人果奶包装生产线设计方法

Design Method of High-Speed Robot Fruit-Milk Packaging Line Based on Petri Net

针对国内饮料行业产品包装生产线升级换代的问题,提出了一种以高速搬运机器人为核心的新型果奶包装生产线设计方法.首先,基于果奶包装生产线的工艺分析,提出用机器人代替人工的新型生产线布局形式;其次,利用Petri网技术建立了该生产线模型,并基于不变量的方法分析了生产线系统的可达性、安全性、无死锁性;最后,在实验测得各个工作站作业时间的基础上,利用EM-Plant软件对生产线进行了仿真.分析和仿真结果表明,采用机器人的新型果奶包装生产线方案可行且有效.

To solve the problem that the production packaging line of domestic beverage industry needs upgrading,a new design method of fruit-milk packaging line using high-speed robot is proposed. Firstly,based on the packaging process analysis,the layout of the line is presented,in which industry robots are applied instead of labor. Then the Petri net model is built and the attainability,boundary and reversibility of the system are proved by the theory of in-variant. Finally,the work station time is obtained experimentally,based on which,the line is simulated by EM-Plant. The analysis and research above show that the new design method is feasible and effective.
