RFID technology helps tobacco logistics
As an extremely efficient, fast and convenient identification technology, RFID technology has a wide range of applications in various industries. Cigarette manufacturers have introduced RFID technology into the tobacco industry logistics system, mainly to improve the efficiency of their tobacco industry production and reduce production costs. The application of RFID technology in tobacco logistics.
Adopt RFID technology to combine the status quo of tobacco companies. To achieve the automation of tobacco storage and efficient management of the warehouse. The system uses middleware as a support platform, attaches RFID tags to cigarette crates, trays and shelves, installs an RFID access control system at the receiving place, and sends the actual receiving and receiving information to the back end, which is arranged by the back-end system. At the same time, the vehicle computer terminal is installed on the forklift, the RFID reading and writing device is connected, the information of the front-end system and the back-end system is transmitted through the wireless local area network, the data exchange and update is realized, and the system locates the forklift position in real time, and conveniently dispatches the forklift.
In the outbound and inbound operations of the three elevated warehouses, a semi-automated approach is introduced to introduce certain automation technologies and machinery, supplemented by manual operations, to achieve a balance between efficiency and cost.
Deploy electronic tags at the bottom of the trays and tobacco stems, and correspondingly deploy readers at the sorting, storage, outlet and sealing machines, and combine the “Tobacco Industry Cigarette Production Management Decision Management System Project (ie No. 1 Project) The provisions of the "" can achieve "one dozen two sweeps" - the cigarette industry enterprises to the production of each piece of cigarettes posted by the competent authority to issue the bar code, and the outbound scanning code and cigarette business enterprises into the warehouse scan code, so that Tobacco authorities can timely grasp and implement effective control over the purchase, production and sales of tobacco companies, realize information collection and connect with the warehouse management system, and transfer data information to the warehouse management system for storage through wired and wireless methods. , analysis, processing, to achieve the purpose of rapid and transparent logistics control.
In order to carry out effective positioning, the cargo space is first encoded, and the encoded information is written into the warehouse management system WMS, generally using address coding.
(1) Warehousing business process design
When the raw materials and tobacco auxiliary materials are put into storage, the forks are used to place the tobacco leaves, tobacco stems, and tobacco materials on the trays with the electronic labels, and the readers at the storage ports scan the pallet electronic labels on the pallets completed by the pallets. Matching the pallet information and the commodity information, the matching information is transmitted to the warehouse management system. The conveyor then delivers the goods to the roadway stacker, where they are stored by the stacker.
When the finished cigarettes are put into storage, the cigarette sorting is first carried out through the sorting lane. An RFID reader is installed at each sorting pass, and the RFID electronic tag on the cigarette case is scanned when the cigarette passes, and the type is quickly recognized. If the type is met, the cigarette is pushed into the track by the side pushing device, and then After the palletizing is completed by the ABB robot, the conveyor sends the whole tray of cigarettes to the storage port, and the tray is scanned and recorded by the RFID reader, and then sent to the stacker platform for storage. .
The warehouse management system (WMS) determines the storage location of the cargo and allocates the storage location according to a preset storage strategy (such as classified random storage), location assignment principle (such as first-in first-out), and cargo inventory status. The information is transmitted to the Warehouse Control System (WCS), which drives the conveyor and the roadway stacker to complete the warehousing operation.
(2) Outbound business process design
When there is a request for delivery, the warehouse management system WMS determines the location of the goods to be delivered according to the inventory status and the delivery rules, and transmits the delivery information (such as the name, quantity, storage location, etc.) of the goods to the warehouse control system WCS. The warehouse control system WCS drives the roadway stacker to take out the goods and send them to the outbound platform through the conveyor. The RFID reader automatically scans the goods or pallet labels to confirm and complete the update of the cargo position information. After the error, the shuttle, forklift or AGV trolley is completed. Deliver the goods to the designated location. The outbound job is completed.
After the delivery is completed, the pallet is manually or automatically sent to the palletizing machine. The warehouse management system WMS allocates the empty cargo space to the empty pallet group, and transmits the information to the warehouse control system WCS, the warehouse control system WCS drives the conveyor and the stacker. Return the empty tray group to the specified location in the warehouse, and then automatically use it when you use it next time.
