Talking about the Application of RFID Technology in Tobacco Logistics Management

　　As an extremely efficient, fast and convenient identification technology, RFID technology has a very wide range of applications in various industries. Cigarette factories introduced RFID technology into the tobacco industry's logistics system, mainly to improve the efficiency of their tobacco industry's production and reduce production costs. The application of RFID technology in tobacco logistics.

　　Using RFID technology, combined with the status quo of tobacco companies. Realize the automation of tobacco storage and the efficient management of the warehouse. The system uses middleware as a supporting platform, attaches RFID tags to cigarette boxes, pallets, and shelves, installs an RFID access control system at the receiving place, and sends the actual receipt and storage information to the backend, and the backend system arranges the storage At the same time, install the on-board computer terminal on the forklift, connect the RFID read-write device, and transmit the information of the front-end system and the back-end system through the wireless local area network to realize the exchange and update of data, and the system locates the position of the forklift in real time to facilitate the dispatch of the forklift.

　　In the entry and exit operations of the three elevated warehouses, a semi-automated method is adopted, and certain automation technology and machinery are introduced, supplemented by manual operations, to achieve a balance between efficiency and cost.

　　Deploy electronic tags at the bottom of trays and tobacco stem boxes, and deploy readers at sorting lanes, warehouse entrances, exits, and carton sealing machines correspondingly, combined with the "Tobacco Industry Cigarette Production and Operation Decision Management System Project (i.e. Project No. 1) )”, which can realize “one cleaning and two scans”—the cigarette industry enterprises will paste the barcode issued by the competent department on each cigarette produced, and carry out the outbound scan code and the cigarette commercial enterprise inbound scan code, so that Tobacco authorities can timely grasp and implement effective control of the purchase, production, and sales information of tobacco companies, realize information collection and reasonably connect with the warehouse management system, and transmit data information to the warehouse management system for storage through a combination of wired and wireless methods , Analysis and processing, to achieve the goal of rapid and transparent logistics control.

　　In order to carry out effective positioning, the cargo location must be coded first, and the code information is written into the warehouse management system WMS, generally using address coding.

　　(1) Warehousing business process design

　　When raw materials and tobacco auxiliary materials are in the warehouse, use a forklift to put tobacco leaves, tobacco stems, tobacco materials, etc. on the tray with electronic labels, and the reader at the entrance of the warehouse will scan the tray electronic labels on the tray with the coded tray to complete For the matching of pallet information and product information, the matching information is transmitted to the warehouse management system. Then the conveyor sends the goods to the aisle stacker, and the stacker performs the storage operation.

　　When finished cigarettes are put into the warehouse, they must first be sorted through the sorting channel. Install an RFID reader at each sorting lane, scan the RFID electronic tag on the cigarette box when the cigarette passes through, and quickly identify its type. If it matches the type, push the cigarette into the lane by the side pushing device, and then Palletizing is carried out by the ABB robot. After the palletizing is completed, the conveyor will send the entire pallet to the warehouse, and the RFID reader will scan and record the pallet, and then the conveyor will send it to the stacker station for warehousing. .

　　The warehouse management system (WMS) determines the storage location of this kind of goods and allocates storage locations based on pre-set storage strategies (such as sorting and random storage), cargo location assignment principles (such as first-in-first-out), cargo inventory status, etc. The information is transmitted to the warehouse control system (WCS), and the warehouse control system drives the conveyor and the aisle stacker to complete the warehousing operation.

　　(2) Outbound business process design

　　When there is an outbound request, the warehouse management system WMS determines the location of the outbound goods according to the inventory status and outbound rules, and transmits outbound information (such as outbound goods name, quantity, storage location, etc.) to the warehouse control system WCS. The warehouse control system WCS drives the aisle stacker to take out the goods and send them to the outbound station through the conveyor. The RFID reader automatically scans the goods or pallet labels for confirmation and completes the update of the cargo location information. After the error is correct, the shuttle, forklift or AGV trolley Deliver the goods to the designated location. The outbound operation is completed.

　　After leaving the warehouse, the pallets are manually or automatically sent to the palletizer, the warehouse management system WMS allocates empty spaces to the empty pallet group, and at the same time transmits the information to the warehouse control system WCS, and the warehouse control system WCS drives the conveyor and stacker Return the empty pallet group to the designated location in the warehouse, and then automatically leave the warehouse for use next time.

　　The use of RFID technology to carry out the overall integration of warehouse management can not only meet the requirements of the distribution operation mode in modern logistics, but also be suitable for large-scale busy logistics distribution, ensuring high-quality data exchange in the supply chain, and can play a role in tobacco monopoly management Great effect.
