Technical Field

[0001] The present invention relates to the technical field of logistics sorting, and in particular to an automatic control system and method for efficient screening, sorting, loading and unloading. Background Art

[0002] With the development of online shopping, the logistics sorting system has been developing faster and faster. The main problem solved by the logistics sorting system is how to use logistics nodes to quickly deliver goods to consumers, which puts forward higher requirements on the logistics industry. Now online shopping goods are generally delivered by merchants to the province where the consumers are located. According to the configuration of logistics nodes, the goods in a certain area are first uniformly delivered to a central city in the area, and then sorted and distributed step by step through the city, and finally delivered to the consumers. However, the logistics sorting system currently used in the market has a complex structure and an unreasonable process design, which not only makes it impossible to achieve efficient automation, but also makes it impossible to classify the goods according to the situation of the goods during the distribution process. The sorting and transportation capacity of the parcel is poor, which also affects the improvement of the transportation efficiency of the car. In addition, the power output part of the sorting system still uses more traditional motors, cylinders, etc. This primary driving method is difficult to cope with the refined sorting operation process. Now there is an urgent need for an automatic control system and method for efficient screening, sorting, loading and unloading with high logistics node transportation efficiency and good logistics classification effect.

[0003] The Chinese invention patent (CN 108238432 A) discloses that the present invention discloses a logistics intelligent sorting system, which includes a parcel feeding device; a control device; a parcel buffer device; a primary sorting device and a parcel subdivision line. The parcel feeding device will first transfer the collected express parcels to the parcel buffer device one by one in an orderly manner, and then the express parcels can be pushed to the primary sorting device one by one through the parcel pushing device. The express parcels after the primary sorting are accurately pushed to the parcel delivery device, and then further transferred to the parcel subdivision line through the discharging device for further sorting and processing; through the coordinated work of the control device and the drive control module, the energy conversion and reversing mechanism can effectively convert the moving power of the parcel sorting vehicle into the pushing force of the express parcel, thereby avoiding the use of traditional power output methods such as motors and cylinders, which can not only realize the highly automated sorting of express parcels, but also achieve high sorting efficiency and precision, and at the same time can save energy and reduce consumption, reduce enterprise operations, and improve economic efficiency.

[0004] The Chinese invention patent (CN 107824465 A) discloses a logistics sorting system provided by the present application, the sorting system includes a conveyor belt, the conveyor belt is driven by a first transmission wheel and a second transmission wheel, the sorting system also includes a driving motor driving the first transmission wheel or the second transmission wheel, a suspension frame is installed on the upper side of the conveyor belt, the suspension frame is sequentially installed with a plurality of grabbing components along the running direction of the conveyor belt, and the inner surface of the conveyor belt is also provided with a plurality of quality sensors corresponding to the grabbing components. It can be seen that the main purpose of the application is to be able to quickly grab the items according to their quality and sort the items from the conveyor belt to the designated location.
