The automatic sorting system generally consists of automatic control and computer management system, automatic identification device, sorting device, main conveying device, pre-processing equipment and sorting crossing.

1、Automatic control and computer management system: it is the control and command center of the whole automatic sorting system. All the actions of the sorting system are decided by the control system. Its function is to identify, receive and process the sorting signal, according to the sorting signal instruction sorting device according to certain rules (such as category, location, etc.) automatic classification of products, so as to determine the flow of products. The source of sorting signal can be obtained by barcode scanning, color code scanning, keyboard input, quality detection, voice recognition, height detection and shape recognition, etc. After information processing, it is converted into the corresponding picking list, warehousing list or electronic picking signal, automatic sorting operation.

2、Automatic identification device: automatic identification device is the basic system that can realize automatic sorting of goods. In the logistics distribution center, the widely used automatic identification system is bar code system and radio frequency system. Bar automatic identification system of the photoelectric scanning installed in different locations of the sorting machine, when the goods in the visible range scanner will automatically read the above barcode information goods, said after the code software can be translated into the barcode of commodity information, at the same time feel the position information of goods on the sorting machine, the information will be automatically transferred to the background of computer management system.

3、Sorting device: it is the main body of the automatic sorting machine, including transmission device and sorting device two parts, the role is to be picked up goods into the sorting crossing. The sorting device is the core equipment of the sorting system.

4、Main conveying device: the role is to transport the material to the corresponding sorting crossing, in order to carry out follow-up operations, mainly by all kinds of conveying machinery, also known as the main conveying line.

5、Pre-processing equipment: sorting system to the main conveying device to transport sorting materials into the feed platform and other auxiliary conveyor and operating platform. The feeding platform has two functions. One is that the operator uses the input device to send the destination address of each sorting commodity into the sorting system as the sorting operation instruction of commodities. The second is to control the time and speed of sorting goods into the main conveying device to ensure that the sorting device can be accurately sorted.

6、Sorting crossing: also known as shunting conveyor line, it is the channel that separates the sorted goods from the main conveyor line into the corresponding cargo collection area. Generally by the chute, conveyor belt, roller and other components of the slide, so that the material from the conveying device to slide into the buffer table, and then warehousing operation or distribution work.
