What influence does modern bar code technology bring to traditional logistics?

Modern bar code technology makes everything in the flow have a unique identity. In a word, modern bar code technology closely combines logistics and information flow, and promotes the informationization of logistics. With China's increasing attention to the logistics industry, the construction of logistics informatization has been put on the agenda, and the application prospect of bar code in logistics enterprises has gradually emerged. Specifically, as a tool of logistics management, the application of bar code mainly focuses on the following links.

(1) Material management. Solutions using bar code technology;

1) By coding materials and printing bar code labels, it is not only convenient for material tracking management, but also helpful for reasonable material inventory preparation, improving production efficiency and facilitating the rational use of enterprise funds. According to industry and enterprise rules, establish a unified material code for purchased production materials to prevent losses and confusion caused by disorderly materials.

2) Print the barcode label of the material to be identified, which is convenient for tracking the material in production management, thus establishing a complete product file.

3) Using barcode technology to manage the warehousing, sales and storage, effectively reducing the inventory cost.

4) Establish material quality inspection files through product codes, generate quality inspection reports, and establish supplier evaluation linked to purchase orders.

(2) Production line logistics management.

The logistics management of bar code production line is the basis of bar code application and product identification code establishment. In production, product identification codes are used to monitor production, collect production test data, collect production quality inspection data, conduct product completion inspection, establish product identification codes and product files, arrange production plans in an orderly manner, monitor production and flow direction, and improve the off-line qualification rate of products.

1) Develop the product identification code format. According to the enterprise rules and industry rules, the coding rules of product identification code are determined to ensure the regularity and unique identification of products.

2) Establish product files. Track the production of products on the production line through product identification bar code, collect product parts and inspection data as product information, and establish product files after the production batch plan is reviewed.

3) Control the production information through the information collection point on the production line.

4) Collect the quality inspection data on the production line through the product identification code bar code, and judge whether the product is qualified according to the product quality standard, so as to control the flow of the product on the production line, establish the product file and print the certificate.

(3) Sorting and transportation. Many industries, such as railway transportation, air transportation, postal communication, etc. There are problems in the sorting and handling of goods, and large quantities of goods need to be accurately loaded into designated carriages or flights in a short time; If a manufacturer produces hundreds of products and needs to classify them into different destinations, it is necessary to expand the site and increase personnel, and human errors often occur. The solution to these problems is to apply logistics identification technology to automatically sort packages or products to different transport machines. All we have to do is stick the pre-printed barcode labels on the delivered items and install a barcode scanner at each sorting point.

(4) warehousing. In the storage system, using bar codes can distinguish different information by applying identifiers. After the information is processed by computer, it is more conducive to the purchase, storage and sale of goods.

(5) Airport access. When the scale of the airport reaches the point where a terminal has to handle more than 10 flights within 2 hours, it must be automated, otherwise it will miss the plane because it is too late to handle the luggage. In the automation system, the advantages of logistics identification technology have been fully reflected. People print bar code labels as needed and tie them on each piece of luggage. The bar code label is a card attached to the luggage handle. According to the requirements of International Air Transport Association (1AIA) standard, the barcode should contain flight number, destination and other information. When the transportation system transports luggage from the check-in to the sorting system, a group of channel scanners (usually composed of 8 scanners) surround the conveyor: up, down, front, back, left and right. The scanner aims at every possible label, even at the bottom of the luggage. When the scanner reads the barcode, it will transmit the data to the sorting controller, and then according to the comparison table, the luggage will be automatically sorted to the conveyor belt of the destination flight.

(6) the goods pass. Like the airport corridor, the cargo corridor is also composed of a set of scanners. The omni-directional scanner can read bar codes in all directions, up and down, back and forth, left and right. These scanners can read barcodes in any direction and on any surface, no matter how big the package is, no matter how fast the belt is conveyed, no matter how small the distance between packages is, all scanners with different formats jointly decide which barcodes need to be decoded at present, and then send one by one information to the host computer or control system.

The cargo scanning channel provides an excellent opportunity for further collection of parcel data. The new generation of goods channel can collect the barcode identifier, the actual package size and weight information of goods at the same time at high speed, and this process does not require manual intervention. Because the parcel delivery service is charged according to the volume and weight, this information is very important for training and calculating the K amount of Yingshan. Now we can obtain this information accurately and efficiently to meet the needs of users.

(7) Dynamic weighing. The combination of dynamic weighing and automatic bar code recognition can obtain the weight of the package by putting the electronic scale on the conveyor without interrupting the transportation operation or manual processing, so that the system can maintain high throughput, and at the same time provide weight information in real time, calculate the net weight, check the weight error and verify the weight range. In an efficient material handling system, dynamic weighing can be integrated with other automated processes, such as barcode scanning, label printing and pasting, parcel sorting, palletizing, inventory management, transportation and other functions.
