Description

Sorting Equipment and Logistics Sorting System {Sorting Equipment and Logistics Sorting System}

The present application relates to the technical field of a logistics transport device, and more particularly, to a sorting device and a logistics sorting system.

The shipping industry is an emerging high value-added industry and is developing at a rapid pace in China. Most of the delivery companies are expanding in the form of cooperative affiliates, and each region is managed collectively at the headquarters, so the number of companies is increasing rapidly. In addition, the delivery industry is expanding its own service field by increasing the sales volume of companies by introducing science and technology facilities, and by increasing the network of branches, main and sub-line. Establishing a service network can maximize the development of a delivery company, and cargo is circulated between local branches and distribution centers, and finally delivered to customers through service branches. Delivery sorting refers to a process in which the distribution center of the delivery company collects cargo according to the customer's order, sorts the cargo, and finally sends it to the distribution center or transportation tool at the next stage.

The shipping industry continues to expand in size from its inception to the present, and it is constantly advancing in the way it operates and technology. In particular, in recent years, e-commerce and Internet shopping have increased rapidly, accelerating the development of delivery companies. However, due to the ever-increasing delivery workload, the problem of “warehouse explosion” of delivery companies continues to increase. In a situation where there are currently two markets, international and domestic, both international and domestic delivery companies must track all cargo after shipment to ensure that the cargo has been delivered to the correct point at the specified time.

As the scale of the shipping industry continues to increase, there are many problems in terms of development. Customer reports of service attitudes, delayed delays, and loss of goods are constantly occurring, and in summary, there is room for great progress in the delivery industry in terms of service and detailed management. Shipping sorting plays a decisive role in whether cargo can be accurately delivered to its destination on time, and solving and improving problems that exist in shipping sorting work improves shipping sorting efficiency and service level of shipping companies. Will have a very big impact on the improvement of

There are three types of sorting work methods commonly used in conventional shipping companies: manual sorting, automatic sorting and semi-automatic sorting. Manual screening is the most primitive screening method, and all steps in the screening process are performed manually, and this method has low unit cost and efficiency, frequent mistakes, and relatively easy recruitment and training for selected personnel. Often used in this small selection center. The automatic sorting work method uses an automatic sorting machine to perform line work, and the automatic sorting machine can identify barcodes in the cargo packaging, so it automatically sorts the freight centered on the corresponding delivery based on the recipient information. It can prevent delay or loss of cargo as much as possible Semi-automatic sorting uses a combination of manual and mechanical devices, and is used in parallel in the process of rotating the cargo. After the cargo is unloaded from the transport vehicle with an automatic transfer belt, a person manually sorts it according to the cargo mark. Although the initial investment in this mode is small, the unit price and the unit price of artificial screening are the same, which faces many problems.

The automatic sorting machine is part of the transmission system and can only change the path direction of an article during the transmission process. Behind the sorter, a number of transmission systems can perform the two functions of transmission and storage in terms of functionality. According to the mechanical structure of the sorting mechanism, it is divided into line-shaft type sorting machine, slider type sorting machine, cross belt type sorting machine, and flip type sorting machine. The line-shaft type sorting machine is relatively inexpensive, but its efficiency is generally low, so it is applied only to sorting operations with low demands for movement efficiency. The slider type sorting machine has a high unit price, has a large occupied area and noise, and has very strong integrity, making it difficult to move, increasing the sorting passage, and having low flexibility due to its low applicability. The cross-belt type sorting machine has high efficiency, but the unit price is very high, and all domestic companies import and use foreign finished products, and it is inconvenient to increase and decrease the length due to its strong integrity, and the demand for control is relatively high. The demand for water is also high.

An object of the present application is to provide a sorting device and a distribution sorting system that increase the applicability and sorting efficiency of the sorting device.
