Description
Technical Field
[0001] The present invention relates to the technical field of logistics management, and in particular to an intelligent warehousing logistics method based on robots and automatic seeding walls. Background Art
[0002] Logistics management refers to the planning, organization, command, coordination, control and supervision of logistics activities in the process of social reproduction, based on the laws of the flow of material entities, and the application of basic management principles and scientific methods, so as to achieve the best coordination and cooperation of various logistics activities, reduce logistics costs, improve logistics efficiency and economic benefits, and ultimately achieve customer satisfaction as the first goal, and take the overall optimization of the enterprise as the purpose, taking information as the center, emphasizing efficiency and effect. The scope of logistics management has now expanded to demand forecasting, procurement, production planning, inventory management, distribution and customer service in addition to transportation, in order to systematically manage the operation of the enterprise and maximize the overall benefits.
[0003] According to data, the traditional method of storing goods is to place them directly in the warehouse or on the shelves of the warehouse. This traditional storage equipment has a simple structure, unreasonable design, limited storage space, and cannot meet the needs of large-scale and wide-range storage. This traditional storage method has inconveniences in terms of both storage and retrieval of goods: the goods are piled up in a messy manner, which is inconvenient to store and take out. Some items that need to be stored for a long time cannot be reasonably and effectively protected, resulting in damage to the items; the storage classification method is unclear during storage, and the items cannot be quickly taken out according to the catalog; the items need to consume a lot of human resources when they are stored and discharged on the shelves, with high labor intensity and low work efficiency; the items also need to be taken off the shelves first, and then transported to the loading site, which consumes more human resources; the loading site of the items is far from the unloading site, and there are many useless works in the middle, which reduces the efficiency of transportation; at the same time, the shelf space utilization rate is low, which cannot meet the storage of large-scale items; the items are inconvenient to manage after storage, and the storage is messy, which is not conducive to management and supervision; these factors restrict the management of logistics warehousing.
[0004] Chinese patent document CN104495185A discloses a "logistics management intelligent warehousing system and warehousing method thereof". Items are stored according to chronological and monthly information, which is convenient for management and supervision. At the same time, the storage barrel is directly used as the loading body, and both loading and unloading are carried out by the storage barrel, which saves the useless work of mid-transportation, and saves the trouble of loading operations to loading on shelves, unloading operations to loading operations. The storage barrel is directly used for one-time transportation, unloading and loading, and the process of loading and unloading items from loading on shelves to storage and then to outbound operations is standardized, which improves work efficiency. The above technical solution has a low coverage rate of orders for pallets entering and leaving the platform, and the platform area is congested when exchanging pallets during the peak outbound period. Summary of the invention
[0005] The present invention mainly solves the technical problems that the original technical solution has low coverage of orders for pallets entering and leaving the platform, and the platform area is congested when exchanging pallets during the peak period of outbound delivery. It provides an intelligent warehousing and logistics method based on robots and automatic seeding walls. In the inbound and outbound process, Skyport is used to complete multi-pallet interaction with AGV, which improves the pallet exchange speed of the platform and reduces congestion in the platform area; in the outbound process, a transfer platform and a loop line are added to increase the upper limit of the platform storage position, so that the group wave range is wider and pallet transportation can cover more orders; Skyport, pallet loop line and transfer box loop line are used to cache a large number of outbound pallets, which smoothes the peak congestion caused by order volume fluctuations; in addition, the load of Skyport and the transfer platform is balanced through intelligent control, traffic is optimized, platform load is balanced, order volume fluctuations are smoothed, and the speed of manual order picking in the final link is improved.
[0006] The above technical problem of the present invention is mainly solved by the following technical solution: The present invention comprises the following steps: S1 After the order is multicast, all the selected pallet tasks are issued and the AGV is assigned to collect the pallets; After the S2 AGV is fully loaded with pallets, it will move to the outbound area for circulation; After the S3 circulation is completed, the AGV and pallets are put into storage; After the goods are stored in the S4 circulation box, they arrive at the automatic seeding wall corresponding to the order; After S5 sowing is completed, the goods are packed into the order box and shipped out.
[0007] In the inbound and outbound processes, Skyport is used to complete multi-pallet interaction with AGV, which improves the pallet exchange speed of the platform and reduces congestion in the platform area; in the outbound process, transfer platforms and loops are added to increase the upper limit of platform storage space, making the group wave range wider and allowing pallet transportation to cover more orders; Skyport, pallet loops and transfer box loops are used to cache a large number of outbound pallets, smoothing out peak congestion caused by fluctuations in order volume; in addition, intelligent control is used to balance the load of Skyport and transfer platforms, optimize traffic, balance platform loads, smooth out fluctuations in order volume, and improve the speed of manual order picking in the final link.
[0008] Preferably, the step S1 specifically includes sending all selected pallet tasks to the vehicle dispatching system, and the vehicle dispatching system assigns AGVs near the pallets to collect the pallets according to the locations of the pallets.
[0009] Preferably, in step S2, after the AGV is fully loaded with the pallet, it goes to the outbound area and selects a Skyport with the shortest queue to prepare for outbound delivery.
[0010] Preferably, in step S2, the AGV docks with Skyport and transfers all pallets of the vehicle body at one time. After the pallets enter Skyport, they are unpacked and docked with the conveyor line. The AGV that has completed unloading goes to the return warehouse area on both sides to dock with the return warehouse Skyport or directly returns to the warehouse to perform new tasks.
[0011] Preferably, in step S2, Skyport docks with the conveyor line, unloads the pallet to the conveyor line branch line, and the conveyor line system evaluates the load of the pallet outbound loop line and the urgency of the pallet demand, and releases the pallet into the pallet outbound loop line. When the pallet circulates in the outbound loop line, the load balance of the transfer platform is considered, and a transfer platform is selected for pushing.
[0012] Preferably, the step S3 specifically includes picking out the required quantity of goods for all multicast orders into a circulation box at the pallet circulation station, returning the pallet to the pallet return loop, and storing the corresponding goods in the circulation box temporarily at the circulation station.
[0013] Preferably, the step S4 specifically includes releasing the flow box after it is fully loaded, entering the flow box outbound loop, and arriving at the picking platform in front of the automatic seeding wall that finally corresponds to the order.
[0014] Preferably, the step S4 further includes that the employee scans the goods in the circulation box and places them into the automatic seeding wall, and the seeding wall completes the seeding. The circulation box that has been picked is returned to the circulation box storage loop and returned to each circulation station. The load of Skyport and the circulation station is balanced through intelligent control. Finally, by introducing the automatic seeding wall, the consumption of picking workers' movement, judgment and verification is reduced, and the picking speed and accuracy are significantly improved.
[0015] Preferably, the pallet return loop has an empty pallet branch. If the pallet is empty, it enters the branch and flows to the storage area. The personnel in the storage area use the empty pallet to bind the incoming goods to establish pallets and inventory. Adding circulation platforms and loops to increase the upper limit of platform storage positions, make the group wave range wider, and pallet transportation can cover more orders. Skyport, pallet loops and circulation box loops cache a large number of outbound pallets, smoothing out the peak congestion caused by fluctuations in order volume.
[0016] As a preferred method, the incoming pallets are sequentially transferred from the conveyor line to the incoming Skyport after interaction; the AGV that performs the incoming task docks with the incoming Skyport, and after the Skyport completes the stacking, it pushes all the pallets on each layer of the AGV at one time; the AGV loads the incoming pallets into the warehouse area, and the pallets are sequentially stored according to the principle of balance to complete the incoming warehouse. In the in-and-out process, the Skyport is used to complete the multi-pallet interaction with the AGV, which improves the pallet exchange speed of the platform and reduces the congestion of the platform area.
[0017] The beneficial effects of the present invention are: 1. Efficient pallet exchange: The present invention introduces Skyport, which greatly shortens the operation time of AGV at the platform, releases the traffic in the outbound area, and greatly improves the efficiency of pallet outbound and backbound.
[0018] 2. Conveyor line cache and intelligent platform load control: The present invention introduces a loop line, and the pallets leaving the warehouse can be cached in the outbound loop line, reducing the situation where the AGV is occupied by waiting pallets; the present invention balances the load of Skyport by intelligently controlling the AGV, balances the load of the transfer platform by intelligently controlling the pallet conveyor line, and balances the load of the picking platform by intelligently controlling the transfer box conveyor line. Through these links, the outbound peak is smoothed, the process shortcomings are reduced, and the picking work tends to be balanced and smooth.
[0019] 3. Efficient final picking: The present invention introduces an automatic seeding wall, which reduces the consumption of pickers' movement, judgment and verification, and significantly improves the picking speed and accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the technical solutions of the present application are further described in detail below through embodiments and in combination with the accompanying drawings. It should be understood that the specific implementation method described here is only an optimal embodiment of the present application, which is only used to explain the present application and does not limit the protection scope of the present application. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0027] The design starting point of this invention is for large-scale automated sorting warehouses, involving intelligent scheduling of picking AGVs, logical algorithms for Skyport interactions, order grouping and decomposition algorithms, conveyor line control, and logic for automatic seeding walls, especially the method design and interaction for the entire process of goods circulation.
[0028] The technical background of this invention is based on an existing large-scale automated sorting warehouse that applies the picking AGV cargo to the platform picking solution. In this warehouse, the order is first sent to the RCS method by clustering according to the distance through the group wave algorithm with the goal of shortening the AGV collection time, and the RCS assigns the AGV to perform the task.
[0029] AGV docks with the picking platform, which is divided into two types: conveyor line platform and shelf platform. For the conveyor line platform, AGV docks with the platform entrance and exit conveyor lines to exchange pallets. The conveyor line platform handles single items and single pieces of goods, and the order box is created in the platform. For the shelf platform, AGV docks with the shelf storage location to exchange pallets. The order is bound to the seed wall partition, and the picker picks according to the order requirements of the seed wall and the pallets that have arrived at the platform.
[0030] In the traditional goods-to-person picking solution, the ants solution, the vehicle-to-carrier-to-person solution can realize the whole entry and exit of multiple pallets, but it is impossible to collect and combine specific pallets. Therefore, the coverage rate of pallets entering and leaving the platform for orders is not high each time. In the currently used picking car solution, the picking car docks the warehouse and the platform to realize the combination of pallets, ensuring the full coverage of pallets for orders. However, when the platform is exchanged, the pallets are exchanged individually, so the speed is slow, and the speed of creating upper-level orders is uneven. When a large number of orders are issued, traffic is restricted due to space reasons. When exchanging pallets during the peak period of outbound delivery, there is congestion near the platform area, which affects the efficiency of outbound delivery.
[0031] Secondly, due to the limited shelf space on the platform, each platform can only accommodate a limited number of orders at the same time, which limits the performance of the group wave algorithm. When the pallet arrives at the platform, the picker needs to pick up the goods from the pallets on the three walls by lighting the lights, and pick them to the seeding wall by clapping the lights. This process requires the picker to find the pallet, clap the lights, and move, which consumes a certain amount of physical energy. The final picking speed of a single platform is also limited by this.
[0032] The technical problems to be solved by the present invention are: 1. Improve the pallet exchange speed of the platform, reduce congestion in the platform area, and optimize traffic. (That is, shorten the service time of the service machine and thus shorten the team leader.) 2. Improve the order coverage of each pallet move.
[0033] 3. Balance the platform load and smooth out fluctuations in order volume.
[0034] 4. Improve the speed of manual order picking in the final stage.
[0035] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe the operations (or steps) as sequential processes, many of the operations (or steps) therein can be implemented in parallel, concurrently, or simultaneously. In addition, the order of the operations can be rearranged. The process can be terminated when its operation is completed, but can also have additional steps not included in the drawings; the process can correspond to a method, function, procedure, subroutine, subprogram, etc.
[0036] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.
[0037] Embodiment: This embodiment is an intelligent warehousing logistics method based on robots and automatic seeding walls, such as Figure 1 , Figure 2 As shown, the following steps are included: After the S1 order is multicasted, all the selected pallet tasks are sent and AGVs are assigned to collect the pallets. Specifically, all the selected pallet tasks are sent to the vehicle dispatching system, and the vehicle dispatching assigns AGVs near the pallets to collect the pallets according to their locations.
[0038] After the S2 AGV is fully loaded with pallets, it will move to the outbound area for circulation.
[0039] After the AGV is fully loaded with a pallet, it goes to the outbound area and selects a Skyport with the shortest queue to prepare for outbound delivery.
[0040] The AGV docks with Skyport and transfers all the pallets of the vehicle body at one time. After the pallets enter Skyport, they are unpacked and docked with the conveyor line. The AGV that has completed unloading goes to the return warehouse area on both sides to dock with the return warehouse Skyport or directly return to the warehouse to perform new tasks.
[0041] Skyport connects to the conveyor line and unloads the pallet to the conveyor line branch line. The conveyor line system evaluates the load of the pallet outbound loop line and the urgency of the pallet demand and releases the pallet into the pallet outbound loop line. When the pallet circulates in the outbound loop line, the load balance of the transfer station is considered and a transfer station is selected for pushing.
[0042] After the S3 circulation is completed, the AGV and pallet will be put into storage, which specifically includes: the pallet picks out the required quantity of goods for all multicast orders into the circulation box at the circulation station, the pallet returns to the pallet return loop, and the circulation box stores the corresponding goods and then temporarily stores them at the circulation station.
[0043] After the S4 transfer box is loaded with goods, it arrives at the automatic seeding wall of the corresponding order. Specifically, the transfer box is released after being fully loaded, enters the transfer box outbound loop, and arrives at the picking station in front of the automatic seeding wall of the final corresponding order. Employees scan the code of the goods in the transfer box and place them into the automatic seeding wall, which completes the seeding. The transfer box that has been picked returns to the transfer box inbound loop and returns to each transfer station. The load of Skyport and the transfer station is balanced through intelligent control. Finally, by introducing the automatic seeding wall, the consumption of pickers' movement, judgment and verification is reduced, and the picking speed and accuracy are significantly improved.
[0044] After S5 sowing is completed, the goods are packed into the order box and shipped out.
[0045] There is an empty pallet branch on the pallet return loop. If the pallet is empty, it enters the branch and flows to the incoming storage area. The personnel in the incoming storage area use the empty pallet to bind the incoming goods to establish pallets and inventory. Adding transfer platforms and loops increases the upper limit of the platform storage space, making the group wave range wider and allowing pallet transportation to cover more orders. Skyport, pallet loops and transfer box loops cache a large number of outbound pallets, smoothing out the peak congestion caused by order volume fluctuations. After the incoming pallets are interacted from the conveyor line, they enter the incoming Skyport in turn; the AGV that performs the incoming storage task docks with the incoming Skyport, and after the Skyport completes the stacking, it pushes all the pallets on each layer of the AGV at one time; the AGV loads the incoming pallet into the storage area, and the pallets are stored in turn according to the principle of balance to complete the incoming storage. In the inbound and outbound process, Skyport is used to complete the multi-pallet interaction with the AGV, which improves the pallet exchange speed of the platform and reduces congestion in the platform area.
[0046] In the inbound and outbound processes, Skyport is used to complete multi-pallet interaction with AGV, which improves the pallet exchange speed of the platform and reduces congestion in the platform area; in the outbound process, transfer platforms and loops are added to increase the upper limit of platform storage space, making the group wave range wider and allowing pallet transportation to cover more orders; Skyport, pallet loops and transfer box loops are used to cache a large number of outbound pallets, smoothing out peak congestion caused by fluctuations in order volume; in addition, intelligent control is used to balance the load of Skyport and transfer platforms, optimize traffic, balance platform loads, smooth out fluctuations in order volume, and improve the speed of manual order picking in the final link.
[0047] When working, the first step is to sort out the internal basic processes of each program control module separately: 1. For the AGV dispatcher, after completing the basic data and program configuration, add the AGV to the dispatcher. Create a simulated order within the dispatcher to ensure that the AGV can perform the task and transport it to the designated location.
[0048] 2. For the Skyport control program, after completing the equipment configuration, add Skyport to the control program. Place the pallet at the Skyport conveyor line port to ensure that Skyport can complete the depalletizing and stacking and correctly record the pallet position.
[0049] 3. For the conveyor line control procedure, after completing the installation of the conveyor line and the barcode scanner, place the correct type of container to ensure that the conveyor line can be correctly controlled and the barcode scanner can read the code normally.
[0050] 4. For the order picking and sowing control program, after completing the installation and configuration of the automatic sowing wall equipment, add the automatic sowing wall to the control program. Through the test order, it is necessary to verify whether the sowing grid can be established, whether the goods are scanned correctly, whether the sowing is accurate after the scanning, and whether the grid can be correctly completed and released after the order is completed.
[0051] The second step is to connect the various program modules, that is, to ensure that the data and physical flow of the two adjacent program modules meet the requirements of the technical documents. This includes the interaction between AGV and Skyport, the interaction between Skyport and the conveyor line, and the interaction between the flow box conveyor line and the picking station.
[0052] The third step is to add the optimization logic required by each module based on the connection, including but not limited to site load balancing, recovery of abnormal scenarios, etc.
[0053] Key technical points: 1.Multi-pallet interaction and efficient circulation By utilizing the one-time interaction of multiple pallets between Skyport and AGV, the pallet exchange speed is significantly improved, and the efficiency of the warehousing and outbound processes is optimized.
[0054] 2. Skyport load balancing and AGV intelligent scheduling AGV dispatch adopts a load balancing strategy to balance the Skyport load to reduce congestion and improve overall operational efficiency.
[0055] 3. Conveyor line loop design and platform load management The innovative dual-loop conveying method design, as well as the additional transfer platforms and transfer box loops, have increased the platform storage space limit and the order coverage of pallet transportation. At the same time, the conveyor lines are used to cache pallets to alleviate peak congestion caused by fluctuations in order volume.
[0056] 4. Integration of automatic seeding wall and optimization of picking process The application of automatic seeding wall significantly improves the speed and accuracy of picking, and reduces the movement, judgment and verification consumption of pickers during the picking process.
[0057] Patent points to be protected: 1. One-time multi-pallet interaction mechanism between Skyport and AGV The specific implementation of this technology includes but is not limited to the design of Skyport, the docking mechanism between AGV and Skyport, and the automatic stacking and destacking of pallets.
[0058] 2. Intelligent control and load assessment mechanism of the conveyor line method.

[0062] 4. Integration and operation of automatic seed wall. The specific configuration and operation process of automatic seed wall and how to integrate it seamlessly with existing warehouse logistics methods.
[0063] Example 1 For outbound process: 1. After each order multicast, all selected pallet tasks will be sent to the vehicle scheduling method. The vehicle scheduling will assign nearby AGVs to collect the pallets according to their location.
[0064] 2. After the AGV is fully loaded with pallets, it goes to the outbound area. Considering the Skyport load balancing, it selects a Skyport with the shortest queue and prepares for outbound delivery.
[0065] 3. AGV docks with Skyport and transfers all pallets of the vehicle body at one time. After the pallets enter Skyport, they are unpacked and docked with the conveyor line. After unloading, the AGV can go to the return warehouse area on both sides to dock with the return warehouse Skyport or return directly to the warehouse to perform new tasks.
[0066] 4. Skyport docks with the conveyor line, unloads the pallet to the conveyor line branch line, and the conveyor line method evaluates the load of the pallet outbound loop line and the urgency of the pallet demand and releases the pallet into the pallet outbound loop line.
[0067] 5. When the pallet is circulated in the outbound loop, the load balancing of the circulation platform is considered and a circulation platform is selected for pushing.
[0068] 6. The pallet picks up the required quantity of goods for all multicast orders into the circulation box at the circulation station, and the pallet returns to the pallet return loop. The circulation box is filled with the corresponding goods and temporarily stored at the circulation station.
[0069] 7. After the transfer box is fully loaded, it is released and enters the transfer box outbound loop line, arriving at the picking platform in front of the automatic seeding wall corresponding to the final order.
[0070] 8. Employees scan the code of the goods in the circulation box and place them into the automatic seeding wall, which completes the seeding. The selected circulation box returns to the circulation box storage loop and returns to each circulation station.
[0071] 9. After sowing is completed, the picker packs the goods into the order box, and the conveyor line transfers them to the packaging and shipping area to complete the delivery.
[0072] For the warehousing process: 1. There is an empty pallet branch on the pallet return loop. If the pallet is empty, it enters the branch and flows to the storage area; 2. Personnel in the incoming area use empty pallets and incoming goods to bind them and create pallets and inventory.
[0073] 3. The incoming pallets pass through the conveyor line and enter the incoming Skyport in turn.
[0074] 4. The AGV that performs the warehousing task docks with the Skyport in the warehouse. After the Skyport completes the stacking, it pushes all the pallets on each layer of the AGV at one time.
[0075] 5. The AGV loads the pallets into the warehouse and places them in order according to the principle of balance to complete the warehousing.
[0076] In the warehousing and outbound processes, the present invention uses Skyport to complete multi-pallet interaction with AGV, thereby improving the pallet exchange speed of the platform and reducing congestion in the platform area.
[0077] In the outbound process, the present invention adds a transfer station and a loop line to increase the upper limit of the platform storage space, making the group wave range wider and allowing pallet transportation to cover more orders. Skyport, pallet loop lines and transfer box loop lines cache a large number of outbound pallets, smoothing out the peak congestion caused by order volume fluctuations.
[0078] In addition, the present invention balances the load of Skyport and the transfer station through intelligent control. Finally, by introducing the automatic seeding wall, the consumption of picking workers' movement, judgment and verification is reduced, and the picking speed and accuracy are significantly improved.
[0079] Skyport and automated sowing wall smart warehousing logistics methods vs. conventional cargo-to-dock smart warehousing methods: 1. Efficient pallet exchange: The present invention introduces Skyport, which greatly shortens the operation time of AGV at the platform, releases the traffic in the outbound area, and greatly improves the efficiency of pallet outbound and backbound.
[0080] 2.

Through these links, the outbound peak is smoothed, the process shortcomings are reduced, and the picking work tends to be balanced and smooth.
[0081] 3. Efficient final picking: The present invention introduces an automatic seeding wall, which reduces the consumption of pickers' movement, judgment and verification, and significantly improves the picking speed and accuracy.
[0082] Example 2 Fanatics e-commerce sorting warehouse in the United States The Fanatics e-commerce sorting warehouse in the United States covers an area of 46,451 square meters, with two floors, each floor has about 180,000 storage spaces. The function of this warehouse is to store e-commerce goods in the sports category (such as jerseys, sneakers, sports water bottles, etc.), sort and pack TOC orders for delivery. This phase of the project is the second floor of the warehouse, with the storage area in the middle, and the delivery area and the inbound area on the east and west sides of the storage area respectively. At present, this phase of the project has been officially put into production. The current daily delivery volume on ordinary weekdays is 20,000 pieces, and the peak is expected to be 80,000 pieces per day. The layout is as follows Figure 3 shown.
[0083] The inbound area consists of an inbound platform, an inbound conveyor line and three inbound Skyports. The inbound process includes: The inbound station creates pallets and inventory; The pallet is transported to the Skyport by the conveyor line; The Skyport receives pallets and stacks them; The AGV docks with the Skyport's outer port to retrieve eight pallets at a time; The AGV stores the body pallets one by one in the storage area, and the warehousing is completed.
[0084] The interaction details and interface design of the goods warehousing process are as follows: Figure 4 shown.
[0085] The storage area consists of 4 rack areas, each with 45 to 90 rows of racks. There are 9 layers of racks in the area, and 41 lanes are formed on the front and back sides for a total of 180 picking AGVs to pass through and load and unload pallets. The AGV uses the bottom camera to scan the ground code to determine the location of the warehouse and perform the task of picking or unloading.
[0086] The outbound area consists of 9 outbound Skyports, 9 return Skyports, pallet outbound loops, transfer stations, transfer box outbound loops, and automatic picking stations / walls. The outbound and return processes include: The outbound order is grouped and issued with pallet handling tasks according to SKU relevance, inventory quantity limit and final seeding station storage location limit (N<=90), such as Figure 5 As shown; AGV collects pallets and transports them to the outbound Skyports located on the north and south sides of the outbound area; Skyport’s external port connects to the AGV to receive the pallet, and after depalletizing, the internal port connects to the conveyor line to push the pallet into the pallet outbound circular conveyor line; The details and interface design of Skyport interaction in the cargo outbound process are as follows Figure 6 shown.
[0087] The circulation station receives the outbound pallet, picks the required quantity of goods for this wave of orders, and puts them into the circulation box. One circulation box can collect multiple orders, and these orders will be bound to the same automatic seeding station / wall as much as possible. After the circulation box is completed, it is released and enters the outbound circulation line of the circulation box; for the pallets that have been collected, if they are empty, they enter the empty box loop and return to the inbound area. If they are not empty, they return to the pallet outbound loop and connect to the return Skyport in the middle area of the outbound area. Refer to the inbound process to complete the return to the warehouse.
[0088] The transfer box enters the automatic seeding wall from the transfer outbound loop. After the operator scans the code of the goods, the automatic seeding wall completes the packing. Each seeding wall can activate up to 90 orders at the same time. The completed transfer box returns to the transfer station through a separate empty transfer box loop.
[0089] The subsequent process of the transfer station is as follows Figure 2 shown.
[0090] Currently, this method is running well on site. Through Skyport's efficient pallet exchange, conveyor line buffering and intelligent platform load control, as well as efficient final picking brought by automatic seeding wall, this method well meets customers' on-time and on-quantity delivery needs.
