Description

Technical Field

[0001] This utility model relates to warehousing systems, specifically to a high-speed picking system with flexible and variable span. Background Technology

[0002] In warehousing and logistics, operators typically pick items from shelves and then move them to workstations for packing. With the rapid development of e-commerce, the workload of piecemeal picking in the e-commerce warehousing industry is increasing, demanding higher speed and accuracy. To improve picking efficiency, save labor, and enhance safety, mobile carriers and automated handling equipment (AWTA) are installed. Storage areas are equipped with multiple aisles, and AWTA moves through these aisles. When picking is needed, the AWTA moves the mobile carrier (carrying the items to be picked) to its designated parking area. At workstations, container handling equipment picks and transfers the target items from the mobile carriers to the workstations for packing, or transfers items from the workstations to the mobile carriers for storage. The picked boxes are then returned to their designated locations on the shelves.

[0003] Automated material handling equipment (AWD) can easily collide with material bins as it moves through aisles, causing damage to the bins, shelves, or container handling equipment. Utility Model Content

[0004] Purpose of the utility model: In view of the above-mentioned shortcomings, this utility model provides a safe, efficient, flexible, and variable-span high-speed picking system.

[0005] Technical Solution: To solve the above problems, this utility model adopts a flexible and variable span high-speed picking system, including several side-by-side shelves, several bidirectional elevators, several picking lines and conveyor lines. The bidirectional elevators are located between the shelves and the picking lines, and the conveyor lines are located on top of the shelves. The several picking lines are arranged side by side, and the bidirectional elevators are located at the transport end of the picking lines. The bidirectional elevators include a lifting platform and a driving device. The driving device drives the lifting platform to move laterally and lift longitudinally. The driving device drives the lifting platform to move laterally to connect with different picking lines and different storage locations on the same shelf layer. The driving device drives the lifting platform to lift longitudinally to connect with storage locations at different heights on the shelves and the conveyor lines.

[0006] Furthermore, the conveyor line includes a freight conveyor line, an outbound conveyor line, and a reversing conveyor line. The freight conveyor line is located directly above the shelf. The freight conveyor line and the outbound conveyor line are connected by a reversing conveyor line, which is used to transfer goods on the freight conveyor line to the outbound conveyor line. The outbound conveyor line is used for the outbound of goods.

[0007] Furthermore, the transport conveyor line includes several delivery locations and several temporary storage locations. Each bidirectional elevator has one delivery location and several temporary storage locations within its transfer range. The bidirectional elevator transfers goods obtained from the picking line to the delivery location. When the goods are delivered, the transport conveyor line stops transporting. After the goods are delivered, the transport conveyor line transports the goods to the buffer location, and the delivery location becomes empty.

[0008] Furthermore, the bidirectional elevator is also used to transfer picking materials from the shelf locations to the picking line, and to transfer goods that have not been completed on the picking line to the shelf locations.

[0009] Furthermore, the shelving is equipped with a mezzanine RGV, which is used to transfer picked raw materials to the storage locations on the shelving.

[0010] Furthermore, the picking system also includes an inbound conveyor line for transporting picking materials. The mezzanine RGV obtains picking materials from the inbound conveyor line and transfers the obtained picking materials to the storage locations on the shelves.

[0011] Furthermore, the mezzanine RGV is used to transfer empty cartons to storage locations on the shelves.

[0012] Furthermore, the picking line has two layers, upper and lower, with a downward-sloping guide platform installed at the end of the picking line away from the bidirectional elevator.

[0013] Furthermore, the conveyor line includes a fireproof roller section, which comprises a plurality of fireproof rollers arranged side by side, and each fireproof roller includes a plurality of rollers arranged at axial intervals. The rollers of adjacent fireproof rollers are arranged alternately along the axial direction.

[0014] Beneficial effects: Compared with the prior art, the advantage of this utility model is that it uses a bidirectional lifting mechanism to transport goods between the buffer rack and the picking line, avoiding collisions between automated handling equipment and bins or racks. This picking system can realize functions such as bulk storage and partial retrieval, splitting and combining orders, automatic sorting, automatic storage, and data management.

[0020] like Figures 1 to 5 As shown, this embodiment of a flexible, variable-span high-speed picking system includes several side-by-side shelves 1, several bidirectional elevators 2, several picking lines 3, conveyor lines 4, and inbound conveyor lines 5. The bidirectional elevators are located between the shelves and the picking lines. Each shelf includes several layers, and each layer includes several storage locations. One shelf 1 corresponds to two bidirectional elevators 2, and one bidirectional elevator 2 corresponds to four picking lines 3. Each picking line 3 has two layers, and the four picking lines are arranged side-by-side. The bidirectional elevators are located at the transport ends of the picking lines, and the end of the picking line 3 away from the bidirectional elevators has a downward-sloping guide surface. In this embodiment, the shelves are temporary storage shelves; raw materials in the storage shelves are transported to the temporary storage shelves for picking.

[0021] The bidirectional elevator 2 includes a lifting platform 21 and a drive unit 22. The drive unit 22 drives the lifting platform 21 to move laterally and lift vertically. The lateral movement of the lifting platform 21 is used to connect with different picking lines 3 and different storage locations on the same layer of the shelf 1. The vertical movement of the lifting platform 21 is used to connect with storage locations at different heights of the shelf 1, conveyor lines 4, and picking lines 3 on different layers. The bidirectional elevator 2 transfers picking materials from storage locations on the shelf to the picking line, transfers goods with incomplete order processing on the picking line to storage locations on the shelf, and transfers goods with completed order processing on the picking line to the conveyor line.

[0022] Conveyor line 4 is located at the top of shelf 1. Conveyor line 4 includes a freight conveyor line 41, an outbound conveyor line 42, and a reversing conveyor line 43. Freight conveyor line 41 is positioned directly above the shelf. Freight conveyor line 41 and outbound conveyor line 42 are connected by reversing conveyor line 43. Reversing conveyor line 43 is used to transfer goods from freight conveyor line 41 to outbound conveyor line 42. In this embodiment, reversing conveyor line 43 reverses at 90°. Outbound conveyor line 42 is used for outbound goods. The conveyor line includes fireproof roller positions, each comprising several fireproof rollers arranged side by side. Each fireproof roller includes several rollers arranged axially at intervals. The rollers of adjacent fireproof rollers are arranged alternately along the axial direction.
