卷烟工业自动导引车(AGV)系统的优化改进

Optimization of AGV System in Tobacco Industry

卷烟工业AGV系统在实际运行中,存在着辅料在运送途中跌落、AGV使用效率偏低、路径欠优化及保养方案缺乏理论依据等问题。为此,对长沙卷烟厂自动化物流AGV系统进行了优化改进：①配盘方式由小盒和条盒混合配盘方式改为小盒和条盒分开以单品牌方式进行配盘,同时机台辅料站台由原来的两用一备改为3用;②废料桶回收和输送调度任务由原来的两个任务改为采用一个任务执行,调度控制系统增加一组I/O点采集AGV与废料房隔离门之间的信息,在机台换牌时针对不同任务采取不同的任务级别;③废料房门前路径采用了双向双车道,K区AGV同向行进路径增加至2~3条;④为保证AGV小车长期稳定运行,制定了周期性的AGV保养制度,以达到保养要求。长沙卷烟厂物流AGV系统优化改进后,提高了AGV系统对生产的保障能力,应用结果表明,AGV系统的平均辅料输送时间由23 min减少到约10 min,提高了物流AGV系统的运行效率,保证了辅料输送的安全和高效。

As a solution to the problems of AGV system,such as material falling during conveying,low efficiency,unsatisfactory route planning and maintenance scheme,the system in Changsha Cigarette Factory was optimized as following： 1） loading the packagings for packet and carton separately according to their brand,using all the 3 platforms rather than only two of them;2） assigning the waste containers＇ recycling and conveying in one task order,and adding a set of I/O terminals to acquire the information between AGV and isolating door of waste room,and different tasks were identified as different levels during cigarette brand changing;3） creating a two-way two-lane passage in front of the waste room door,and arranging 2 to 3 routes in K zone and the route for one forward direction;4） to ensure the long-term reliable running of AGV,a regular maintenance system was established.After optimization,the production support capability of AGV system was increased.The application results showed that the average material conveying time of AGV reduced from 23 minutes to about 10 minutes,the running efficiency of the AGV system was improved.
