Application of RFID to automatically sort goods

The rapid development of e-commerce and logistics industries will put great pressure on warehouse management of goods, which also means the need for efficient and centralized cargo sorting management. More and more centralized warehouses for logistics goods are no longer satisfied with using traditional methods to complete heavy and complex sorting tasks. The introduction of UHF RFID technology has made the sorting work automated and informatized, improving the efficiency of goods circulation.

The traditional method uses barcode labels to identify goods. During the transportation process, the goods are sorted through recognition of barcodes. However, when using barcodes for sorting, you need to scan the barcodes. There are problems such as low sorting efficiency and low reading accuracy. This means that logistics companies need to invest more manpower and material resources in sorting goods, and it is difficult to do so. Automation and intelligent management.

solution

The main implementation method of the UHF RFID automatic sorting system is to paste electronic tags on the goods. By installing reader equipment and sensors at the sorting point, when the goods with electronic tags pass through the reader equipment, the sensors recognize that goods are coming. The reader is notified to start reading the card. The reader reads the label information on the goods and sends it to the backend. The backend controls which sorting port the goods need to go to, thereby realizing automated sorting of goods and improving accuracy and efficiency.

The steps for UHF RFID automatic sorting are:

1. Before starting the sorting operation, the picking information must first be processed, and the picking information is formed based on the sorting list output by the order processing system. The sorting machine is used to automatically sort the packages to improve the accuracy of sorting.

2. Input relevant goods and classification information into the automatic control system through the information input device of the automatic classification machine.

3. The automatic sorting system uses a computer control center to automatically process goods and classification information and form data.

The order is transmitted to the sorting machine.

4. The sorting machine uses automatic identification devices such as UHF radio frequency identification technology to automatically classify and pick goods. When the goods are moved to the conveyor through the transplanting device, they are moved from the conveying system to the classification system, and then transported out by the classification crossing device. The pre-set classification requirements push the express goods out of the sorting machine to complete the sorting operation.

User benefits

The application of UHF RFID technology comprehensively optimizes logistics express processing to achieve paperless express delivery, intelligent parcel collection, less-manned sorting, convenient delivery, and cost minimization, etc., and solve the current problems of using face orders in the domestic express industry. It is wasteful and not environmentally friendly. The manual sorting process causes problems such as low sorting efficiency, slow speed, damaged express items, high cost of rough sorting, insufficient control of package contraband, and leakage of customer information.

Able to complete a larger amount of sorting work more efficiently: Since the automatic sorting system is not restricted by climate, time, human physical strength, etc., it can operate continuously. A common automatic sorting system can achieve a sorting rate of 7,000 to 10,000 pieces per hour. If manual work is used, only about 150 pieces can be sorted per hour. At the same time, the sorting personnel cannot work continuously for 8 hours under this kind of labor intensity.

The sorting error rate is extremely low: the sorting error rate of the automatic sorting system mainly depends on the accuracy of the input sorting information, which in turn depends on the input mechanism of the sorting information. If input by manual keyboard or voice recognition , the error rate is above 3%. If electronic tags are used, there will be no errors. Therefore, the current main trend in automatic sorting systems is to use radio frequency identification technology to identify goods.

Sorting operations are basically unmanned: One of the purposes of establishing an automatic sorting system is to reduce the use of personnel, reduce the labor intensity of workers, and improve the efficiency of personnel. Therefore, the automatic sorting system can minimize the use of personnel. When used, it is basically unmanned.
