Description

Technical Field

[0001] The utility model relates to the technical field of cargo picking, in particular to a multi-level cargo picking system. Background Art

[0002] At present, due to the rapid development of e-commerce, new demands have been put forward for cargo warehousing and cargo picking. Due to the explosive growth of orders, it is necessary to meet both order processing capacity and order processing efficiency, and in order to reduce site costs, it is necessary to minimize the space occupied by equipment. In the prior art, patent CN219448097U discloses a typical cargo picking system, which can deliver goods to the target grid according to orders to achieve simultaneous picking of multiple orders. In this way, order processing is relatively chaotic, and different types of goods or orders sent to different areas are mixed together for picking. After the picking is completed, the picked goods need to be sent to the next sorting line for secondary picking. In this way, there are many intermediate links and low efficiency. In addition, setting up picking systems for multiple levels of picking tasks requires a large layout space, and the site cost is also high. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a multi-stage cargo picking system with compact layout and high sorting efficiency.

[0004] Technical solution: To achieve the above-mentioned purpose, the multi-stage cargo picking system of the utility model comprises a sorting main line and a sorting device placed on the side of the conveying direction of the sorting main line; the sorting main line has a first output mechanism capable of outputting cargo to the sorting device;

[0005] The sorting device comprises a multi-layered sorting branch line, and each layer of the sorting branch line has a cargo collection unit on its side; the sorting device also comprises an elevator and a second output mechanism capable of moving along the sorting branch line;

[0006] The lifting unit of the lift can be docked at any of the sorting branches.

[0007] Furthermore, the main sorting line further comprises a circulating conveying unit, the number of the first output mechanisms is multiple, the first output mechanisms are installed equidistantly, and the first output mechanisms are driven by the circulating conveying unit. The circulating conveying unit can be in the form of a belt, a synchronous belt, a chain, etc.

[0008] Furthermore, the first output mechanism is a conveying mechanism, and the conveying mechanism includes a conveyor belt, a conveyor chain, and a conveyor roller; the conveying direction of the first output mechanism is perpendicular to the conveying direction of the circulating conveying unit.

[0009] Furthermore, the sorting device also includes a buffer mechanism placed between the elevator and the sorting main line.

[0010] Furthermore, the cache mechanism has a conveying function. By providing the cache mechanism, each sorting device has a cache capacity and can store a plurality of goods to be sorted. The cache mechanism can sequentially convey the goods to be sorted to the elevator.

[0011] Furthermore, the head end of the sorting main line is provided with a cargo information acquisition unit; the cargo information acquisition unit may be in the form of a barcode scanner, or an RFID identification unit, etc. The side of the sorting main line is provided with a first recycling unit; in the conveying direction of the sorting main line, the first recycling unit is located at the rear side of the cargo information acquisition unit and in front of all the sorting devices.

[0012] Furthermore, a second recycling unit is provided at the end of the main sorting line.

[0013] Furthermore, the second output mechanism has a trolley that can move along the sorting branch line, and the trolley has a conveying mechanism in the form of a flat belt, a conveyor roller, etc. The conveying direction of the conveying mechanism is perpendicular to the extension direction of the sorting branch line.

[0014] When picking, the goods are put into the head end of the sorting main line, and the goods information acquisition unit tries to obtain the goods information. When the acquisition fails, the first output mechanism directly outputs the goods to the first recovery unit; when the acquisition succeeds, the sorting main line transports the goods backward, and delivers the goods to different sorting devices through the first output mechanism. Different sorting devices can pick different types of goods (such as goods stored at room temperature and goods that need cold chain transportation), and different sorting devices can also pick orders to be delivered to different regions; delivered to the cache mechanism, the cache mechanism inputs the goods into the elevator in turn, and the elevator transports the goods to the sorting branch line of the target layer. The second output mechanism on the sorting branch line takes over the goods and carries the goods along the sorting branch line to the corresponding collection unit, and outputs the goods to the collection unit. When the sorting device does not have enough cache positions, the goods continue to move along the sorting main line to the second recovery unit. After the goods in the second recovery unit reach a certain number, the goods in the second recovery unit are continued to be put into the sorting main line for sorting.

[0015] Beneficial effects: The multi-level cargo picking system of the utility model can first carry out large-scale picking according to classification standards such as cargo attributes and regions, so that the cargo enters the corresponding sorting device, and the sorting device then carries out specific sorting according to the order or classification standards. The overall layout is compact, and the structural configuration of each level of sorting is reasonable. While carrying out multi-level sorting, it can effectively reduce the floor space of the picking system. At the same time, there are no unnecessary intermediate links, and the sorting efficiency is very high. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In other embodiments, Figure 4 As shown, elevators 4 are installed on both sides of the sorting branch line 2, and the first output mechanism 1 can transport goods to each elevator 4, so that the capacity of each sorting device B to receive goods can also be increased.
