Optimization of AGV System in Tobacco Industry

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.
