In the new redrying workshop of Huidong Redrying Plant, which is 340 meters long and 80 meters wide, it is not only its "large" that is eye-catching. In the corner of the workshop, there are neatly arranged several five-story steel frames in blue and red. UHF RFID reader antenna is added to each AGV, which is better with the efficiency of RFID handheld readers.
In the past, after the tobacco leaves entered the redrying plant, the nicotine value and other indicators had to be proportioned manually, and then carried on the production line one by one by the method of shoulder and hand, which was labor intensive and easy to make mistakes. The elevated recipe library realizes an unmanned and information-based production methods.
"Every box of tobacco leaves in the warehouse is marked with an RFID tag, and the nicotine value information in it is recorded in the computer." said Chen Xiaowen, deputy chief of the equipment section of the Huidong Redrying Plant. When production is needed, the computer will automatically calculate which frame of tobacco leaves are needed, and the fully automatic AGV trolley will identify and find the specified tobacco leaves according to the instructions of the computer, and then transport them to the production line after they are picked up by a robotic arm. "The whole process has realized unmanned stacking and unmanned pickup, and the efficiency has increased by more than 50%." Chen Xiaowen said.
