Description

An automatic sorting system for goods

technical field

The invention belongs to the technical field of logistics and transportation, and in particular relates to an automatic sorting system for goods.

Background technique

At present, the commonly used cargo sorting methods in express logistics, according to the packaging particularity of the express delivery industry, generally adopt two methods: manual sorting and automatic sorting. Goods need to complete at least three actions before delivery: scanning, weighing and bagging. With the rapid growth of the contemporary social logistics industry and the improvement of people's requirements for delivery time and service quality, as well as the restriction of labor costs on the development of the logistics industry, more and more logistics companies hope to use automated operations to reduce costs and improve efficiency. Especially in the express delivery industry, the use of automatic sorting systems is the general trend. The traditional cross-belt or slider sorting system is relatively complex, requires large equipment investment, and occupies a large space, resulting in a long implementation period and complex daily maintenance. Low-cost automatic sorting technology to solve the express requirements of less manpower, large amount of goods and high timeliness. In addition, the existing cargo sorting method cannot dynamically weigh the goods during the sorting process. After sorting, it is easy to cause overweight goods in a single container. Once the goods are overweight, they will be stacked and transported.
