Detailed Implementation

[0058] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0059] Please see the appendix Figure 1 -Appendix Figure 6 This application proposes a B2B shipping system combining pallet warehouses and multi-pass warehouses, including a pallet warehouse 1, a multi-pass warehouse 2, a two-layer pallet conveyor line 3, a two-layer box conveyor line 4, a picking department, a screw conveyor 6, a single-layer pallet conveyor line 7, and a single-layer box conveyor line 8. The pallet warehouse 1 has two levels of entrances and exits; the multi-pass warehouse 2 also has two levels of entrances and exits. Both pallet warehouse 1 and multi-pass warehouse 2 are common automated storage and retrieval systems (AS / RS), representing a highly efficient and densely packed automated warehousing system. They feature two levels of entrances and exits, and rapid storage and retrieval of goods are achieved through shuttle vehicles running on the rack tracks at each level. Pallet warehouse 1 is generally used to store single, multi-palletized pallets, while multi-pass warehouse 2 is used to store various products.

[0060] The entrance of the second-level pallet conveyor line 3 connects to the second-level entrance / exit of the pallet warehouse 1. Specifically, as shown in the attached diagram... Figure 2 The pallet warehouse 1 is equipped with several stacker cranes 110 and several chain conveyor docking stations 120 at intervals at its exit. The chain conveyor docking stations 120 connect the stacker cranes 110 and the second-level pallet conveyor line 3 in series. According to system instructions, pallets from designated locations within the pallet warehouse 1 are transported to the stacker cranes 110 via shuttle cars inside the pallet warehouse 1. The stacker cranes 110 then connect to the chain conveyor docking stations 120, thus realizing the pallet transport from the pallet warehouse 1 to the stacker cranes 110, then to the chain conveyor docking stations 120, and finally to the second-level pallet conveyor line 3, completing the pallet outbound operation. More specifically, several stacker cranes 110 are arranged at intervals on one side of the pallet warehouse 1 according to the number of warehouse rows. One stacker crane 110 corresponds to two rows of warehouse rows and two chain conveyor docking stations 120, which not only allows for a compact arrangement of workstations in multi-pallet warehouses but also improves outbound efficiency.

[0061] As attached Figure 1 Appendix Figure 2 Appendix Figure 5As shown, the two-layer box conveyor line 4 includes: a two-layer box conveyor main line 4a; several two-layer box conveyor first branch lines 4b, whose outlets are respectively connected to the two-layer box conveyor main line 4a; a two-layer box conveyor second branch line 4c, located downstream of any of the two-layer box conveyor first branch lines 4b, whose inlet and outlet are respectively connected to the two-layer box conveyor main line 4a and the two-layer inlet and outlet of the multi-passage warehouse 2; and a two-layer box conveyor third branch line 4d, located downstream of any of the two-layer box conveyor first branch lines 4b. The conveying begins from the two-layer box conveyor first branch line 4b, passes through the two-layer box conveyor main line 4a, and then branches off. A portion of the product enters the multi-passage warehouse 2 from the two-layer box conveyor second branch line 4c for storage, while a portion of the product enters the screw conveyor 6 from the two-layer box conveyor third branch line 4d and descends to the first layer.

[0062] As attached Figure 2 As shown, the picking unit includes: a plurality of unpacking stations 310, which are respectively connected to the two-layer pallet conveyor line 3 and arranged at intervals; a plurality of box-type loading stations 410, which are respectively arranged on the first branch line 4b of the two-layer box-type conveyor; a plurality of labeling stations 420, which are respectively arranged on the first branch line 4b of the two-layer box-type conveyor and are respectively located downstream of the plurality of box-type loading stations 410; and a plurality of robotic arms 5, which correspond to the plurality of unpacking stations 310 and the plurality of box-type loading stations 410. Specifically, pallets are conveyed from the second-level pallet conveyor line 3 to different unpacking stations 310. Then, robotic arms 5 perform unpacking operations, breaking down the target number of pallets into individual pallets and placing them one by one on the box-type loading station 410. At the box-type loading station 410, the robotic arms 5 remove the products from the incoming pallets carrying the products and place them onto the individual pallets. Each individual pallet and product combination is defined as a finished product. The finished product is then conveyed along the required path using the second-level box-type conveyor line 4. At the labeling station 420, a labeling machine labels the finished product, thus integrating the pallet storage 1 and the multi-pass storage 2, enabling the second-level box-type conveyor line 4 to not only convey products but also pallets. More specifically, one robotic arm 5 corresponds to two unpacking stations 310 and two box-type loading stations 410, which helps improve unpacking efficiency.

[0063] In one embodiment, a weighing and barcode scanning station 430 is set up on the main double-layer box conveyor line 4a and downstream of the first double-layer box conveyor branch line 4b. This station is used for weighing and barcode scanning of the finished products after labeling. Based on the barcode scanning results, the finished products are diverted to the second double-layer box conveyor branch line 4c or the third double-layer box conveyor branch line 4d.

[0064] In one embodiment, the plane of the second-layer box conveyor main line 4a is offset from the second-layer pallet conveyor branch line 3c, and the height difference is compensated by a spiral lifting method for the first branch line 4b of the second-layer box conveyor.

[0065] As attached Figure 1 and attached Figure 6 As shown, the inlet of the screw conveyor 6 connects to the outlet of the third branch line 4d of the second-layer box conveyor, and the outlet of the screw conveyor 6 connects to the inlet of the first-layer box conveyor line 8; the inlet of the first-layer pallet conveyor line 7 connects to the first-layer entrance / exit of the pallet warehouse 1; and the inlet of the first-layer box conveyor line 8 connects to the first-layer entrance / exit of the multi-passage warehouse 2. Specifically, several stacker cranes 110 and several chain conveyor connection stations 120 are arranged at intervals at the outlet of the pallet warehouse 1. The chain conveyor connection station 120 connects the stacker cranes 110 and the first-layer pallet conveyor line 7 in series. Therefore, there are two delivery paths for pallets: one is direct delivery from pallet warehouse 1 - stacker crane 110 - chain conveyor connection station 120 - first-layer pallet conveyor line 7, and the other is delivery from screw conveyor 6 - first-layer pallet conveyor line 7; the product delivery path is: screw conveyor 6 - first-layer box conveyor line 8.

[0066] During system operation, pallets are retrieved from pallet warehouse 1, pass through stacker crane 110, chain conveyor connection station 120, and second-level pallet conveyor line 3 to reach unpacking station 310. Robotic arm 5, according to system instructions, unpacks the pallets one by one into individual pallets and places them on box-type loading station 410, and picks up products and assembles them into finished products on individual pallets on box-type loading station 410. Finished products are then sequentially transported through the first branch line 4b of the second-level box-type conveyor, the main line 4a of the second-level box-type conveyor, and the second branch line 4c of the second-level box-type conveyor to enter the storage of multi-pass warehouse 2 from the second-level entrance and exit. When shipment is required, products are shipped from the first-level entrance and exit of multi-pass warehouse 2 to the first-level box-type conveyor line 7, or products are shipped directly through the first branch line 4b of the second-level box-type conveyor, the main line 4a of the second-level box-type conveyor, the third branch line 4d of the second-level box-type conveyor, the screw conveyor 6, and the first-level box-type conveyor line 4.

[0067] As attached Figure 2 Appendix Figure 3 Appendix Figure 4 As shown, the second-level pallet conveyor line 3 includes: a second-level pallet conveyor main line 3a, connecting to several unpacking stations 310; a second-level pallet conveyor first branch line 3b, whose entrance connects to the second-level pallet conveyor main line 3a; a second-level pallet conveyor second branch line 3c, whose entrance connects to the second-level pallet conveyor first branch line 3b; a second-level pallet conveyor third branch line 3d, whose entrance connects to the second-level pallet conveyor second branch line 3c; and a second-level pallet conveyor fourth branch line 3e, connecting to several unpacking stations 310, whose entrance connects to the second-level pallet conveyor second branch line 3c, with one side of its exit connecting to a floor elevator 9, and the other side of its exit connecting to the second-level entrance / exit of the pallet warehouse 1; wherein, the exit of the floor elevator 9 connects to the first-level pallet conveyor line 7. By arranging the second-level pallet conveyor line 3, more conveying paths are provided for pallet stacks or individual pallets.

[0068] Furthermore, the second-level pallet conveyor line 3 also includes: a pallet unpacking machine 10, located at the first branch line 3b of the second-level pallet conveyor; and a reverse picking pallet stacking station 320, which connects to the second branch line 3c of the second-level pallet conveyor and is also connected to one of the robotic arms 5 in the picking section. Depending on the picking quantity, the remaining pallets after picking can be re-stacked, which not only makes B2B order processing more flexible but also saves some of the storage space required in the pallet warehouse 1.

[0069] Generally, to facilitate fast delivery and improve efficiency, reverse picking is performed on pallets where the number of unpacked pallets exceeds half the number of original pallets. Taking the number of unpacked pallets (i.e., how many pallets the order requires) as m, the total number of pallets in the original pallet as n, and the total number of pallets and the number of unpacked pallets (nm) as t, as an example: When m ≤ 1 / 2n, robot arm 5 performs a forward picking operation, removing m pallets from unpacking station 310 and placing them at box-type loading station 410. These m pallets are then conveyed to the next station by the second-layer box-type conveyor line 4, and the remaining t pallets are returned to pallet storage 1 via the second-layer pallet conveyor line 4e. When m > 1 / 2n, robot arm 5 performs a reverse picking operation, removing t pallets from unpacking station 310 and sending them to the reverse picking pallet racking station 320. Utilizing the connection between unpacking station 310 and the second-layer pallet conveyor line 4e, the remaining m pallets at unpacking station 310 are transported via the second-layer pallet conveyor line 4e. 3e is conveyed to the floor elevator 9, which lowers m pallets to the first floor and conveys them to the first-floor pallet conveyor line 7. The first-floor pallet conveyor line 7 directly ships the pallets, speeding up the shipping of the pallet stacks. Pallet warehouse 1 provides mother pallets to depalletizer 10 through stacker crane 110, chain conveyor connection station 120, and second-floor pallet conveyor first branch line 3b. After depalletizer 10 removes a single mother pallet from the mother pallet stack, the mother pallet passes through the second-floor pallet conveyor first branch line 3b and the second-floor pallet conveyor second branch line 3c to reach the reverse picking stacking position 320. The removed t pallets are placed on the reverse picking stacking position 320 by robot arm 5 and stacked with the mother pallet. Then, they are returned to pallet warehouse 1 for temporary storage in sequence from the second-floor pallet conveyor second branch line 3c, the second-floor pallet conveyor third branch line 3d, and the second-floor pallet conveyor fourth branch line 3e.

[0070] Please see the appendix Figure 6 Appendix Figure 7 Appendix Figure 8The first-level pallet conveyor line 7 includes: a pallet line feeding station 710, which connects to the entrance of the first-level pallet conveyor line 7; several pallet scanning stations 720, which connect to the first-level pallet conveyor line 7 and are arranged at intervals; and several pallet shipping stations 730, which are respectively connected downstream of the several pallet scanning stations 720. A whole pallet enters the first-level pallet conveyor line 7 from the pallet line feeding station 710, and then is sent to the pallet warehouse 1 for storage via the chain conveyor connection station 120 and the stacker crane 110. When leaving the warehouse, the pallet is diverted from the pallet warehouse 1, the stacker crane 10, the chain conveyor connection station 120, and the first-level pallet conveyor line 7 to different pallet scanning stations 720, or from the floor elevator 9 and the first-level pallet conveyor line 7 to different pallet scanning stations 720. Scanners at the pallet scanning stations 720 scan the barcodes on the five sides of the pallet and upload the results to the system. Finally, the pallet arrives at the pallet shipping station 730 for shipment and loading. The number of pallet shipping stations 730 should be arranged at least three as needed, and shipping operations can be carried out by directly connecting with manual pallet jacks and forklifts.

[0071] In one embodiment, a rotary table 740 is provided between the pallet scanning station 720 and the pallet shipping station 730 to adapt the pallet shipping direction to the pallet shipping station 730. The rotary table 740 is used to switch the direction of the pallet, facilitating pallet jack and forklift operations.

[0072] Please see the appendix Figure 6 Appendix Figure 7 Appendix Figure 9 The single-layer box conveyor line 8 includes: a single-layer box conveyor main line 8a; a single-layer box conveyor first branch line 8b, whose inlet is connected to the screw conveyor 6 and whose outlet is connected to the single-layer box conveyor main line 8a; a product scanning station 810, which is connected to the single-layer box conveyor main line 8a and the single-layer entrance / exit of the multi-passage warehouse 2 respectively; a weighing station 820, which is set on the single-layer box conveyor main line 8a and located downstream of the product scanning station 810; several manual shipping stations 830, which are spaced apart on the single-layer box conveyor main line 8a and located downstream of the weighing station 820; and a product abnormality station 840, which is set at the outlet of the single-layer box conveyor main line 8a. Products descending from the spiral conveyor 6 to the first floor sequentially pass through product scanning station 810, where barcodes on all five sides of the product are scanned and uploaded to the system. They then pass through a dynamic weighing scale at weighing station 820 for weighing, and finally enter different manual shipping stations 830 for shipment. Products with scanning errors flow to the last product error station 840 to await manual processing. Therefore, the single-layer layout of this system can accommodate both full pallet shipping and single-box shipping modes, making order processing more flexible.

[0073] In one embodiment, a manual loading station 210 is set at the entrance and exit of the multi-passage warehouse 2 and is connected to the first main line 8a of the first-level box conveyor. A single box of products can be entered and stored from the first-level entrance and exit of the multi-passage warehouse 2 after the barcode information is scanned and matched with the warehouse location at the manual loading station 210.

[0074] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
