Description

Logistics sorting system and sorting method thereof

Technical Field

The invention relates to the technical field of warehouse logistics and management thereof, in particular to a logistics sorting system and a sorting method thereof.

Background

With the continuous improvement of living standard of people and the popularization of online shopping, the living standard of people is increasingly improved, and the pursuit of material diversification becomes social fashion. With the rapid development of electronic commerce, unprecedented development opportunities are brought to the logistics industry, and a serious challenge is also provided. How to sort goods with high efficiency, low cost, flexibility and accuracy is always a difficult problem in the industry.

Traditional goods letter sorting generally is carried out for the manual mode, and is intelligent and swift inadequately, still faces inefficiency, error rate height, artifical intensity big, recruitment is difficult, the difficult scheduling problem of management simultaneously. Along with the development of the logistics industry of China, some mechanical and automatic logistics sorting equipment appears, and particularly, the application of various sorting machines greatly improves the logistics sorting efficiency. The sorting machine is a key device of a goods sorting processing center, and although the working form and the implementation mode of the device are different, the principle of the device is that the information of goods is identified and recorded, then the goods in a designated area are sent into a conveying device, and the goods are sent to a designated grid through the conveying device.

At present, however, the goods logistics in the existing express delivery industry include standard logistics and non-standard logistics, wherein the standard logistics are packaged by standard rectangular logistics cartons or other standard logistics equipment. For a sorting machine, when the standard logistics pieces are used for sorting goods, the sorting efficiency is high and the sorting error is low; however, for some non-standard logistics pieces, due to the fact that the sizes, the lengths and the weights of goods are different, materials adopted by outer packages are different, and even some special-shaped goods logistics pieces exist, sorting steps are different; when the non-standard logistics pieces are automatically sorted, the sorting efficiency is low, the wrong sorting is easy to occur, and even some goods are crushed and damaged in the stacking or transportation process due to the size or structure difference; the abnormal goods are not processed normally, and the goods are only taken off from the equipment or directly separated by a mechanical arm or a shifting fork and other mechanisms, and are not processed automatically.

For the above reasons, there is a need for an improvement of the existing sorting equipment and an automatic logistics sorting scheme, which improves the sorting efficiency and success rate of non-standard logistics.
