Sorting machine is according to the pre-set computer instructions on the items to be sorted, and will be sorted out of the items sent to the designated location of the machinery. With the development of laser scanning, bar code and computer control technology, the use of automatic sorter in logistics is becoming increasingly common.

1. Continuous, high-volume sorting of goods. As a result of the use of large-scale production in the automatic operation of the assembly line, the automatic sorting system is not subject to the climate, time, physical strength and other constraints, can be run continuously, at the same time, due to the automatic sorting system per unit of time to sort the number of pieces of the automatic sorting system, so the automatic sorting system's ability to sort is running continuously for more than 100 hours per hour can be sorted 7,000 pieces of packaged goods, such as manual labor can only be sorted 150 pieces per hour. At the same time, the sorting staff can not work continuously for 8 hours under this labor intensity.

2, sorting error rate is very low. Automatic sorting system sorting error rate depends mainly on the size of the accuracy of the input sorting information, which in turn depends on the sorting information input mechanism, if the use of manual keyboard or voice recognition input, the error rate of more than 3%, such as the use of bar code scanning input, unless the bar code printing itself has errors, otherwise there will be no error. Therefore, the current automatic sorting system mainly uses bar code technology to identify goods.

3, sorting operations to achieve basic unmanned. One of the purposes of the establishment of automatic sorting system abroad is to reduce the use of personnel, reduce the labor intensity of workers, improve the efficiency of the use of personnel, so the automatic sorting system can minimize the use of personnel, basically unmanned. Sorting operation itself does not require the use of personnel, the use of personnel is limited to the following work:

(1), the delivery vehicle arrives at the feed end of the automatic sorting line, the manual pickup.

(2) The operation of the sorting system is controlled manually.

(3) At the end of the sorting line, the sorted goods are loaded and loaded manually.

(4) The operation, management and maintenance of the automatic sorting system.
