[0050] The following will describe in detail the specific implementation manners of the present application with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustration and explanation of the present application, and are not used to limit the present application.

[0051] The following describes a three-dimensional warehouse storage system and its control method of the present application with reference to the accompanying drawings.

[0052] As Figures 1 to 3 shown, the present application provides a three-dimensional warehouse storage system and its control method. Among them, the three-dimensional warehouse storage system includes a three-dimensional warehouse 10, a lifting device 30, and a transfer trolley device 40. The three-dimensional warehouse 10 includes a temporary storage layer 11 at the bottommost layer and a storage layer 12 above the temporary storage layer 11. A four-way vehicle device 20 is provided in the storage layer 12. The lifting device 30 is located on one side of the three-dimensional warehouse 10 and can be lifted between the temporary storage layer 11 and the storage layer 12. The transfer trolley device 40 can be transferred between the sorting area 50, the loading and unloading area 35 of the lifting device 30, and the temporary storage layer 11.

[0053] Please refer to Figure 1 , the temporary storage layer 11 is located at the bottommost layer of the three-dimensional warehouse 10, the storage layer 12 is above the temporary storage layer 11, and the number of storage layers 12 can be multiple, and multiple storage layers 12 are arranged in sequence in the up and down direction. A four-way vehicle device 20 is provided in the storage layer 12. The four-way vehicle is used to carry the materials in the storage layer 12. The four-way vehicle has the advantages of high efficiency, flexibility, and safety, and is widely used in modern warehousing and logistics management. The lifting device 30 is located on one side of the three-dimensional warehouse 10. The lifting device 30 can be lifted between the temporary storage layer 11 and the storage layer 12 to transport the materials to the temporary storage layer 11 or the storage layer 12. The lifting device 30 has a loading and unloading area 35, and the loading and unloading area 35 is used for loading and unloading materials.

[0054] A sorting area 50 is provided outside the three-dimensional warehouse 10. The sorting area 50 is used to classify and process the materials according to the order requirements. This process can be carried out before the materials enter the three-dimensional warehouse 10 or when the materials are out of the three-dimensional warehouse 10 to ensure the accuracy and timeliness of each order. The transfer trolley device 40 can be transferred between the sorting area 50, the loading and unloading area 35 of the lifting device 30, and the temporary storage layer 11.

[0055] In the three-dimensional warehouse storage system of this application, the bottommost layer of the three-dimensional warehouse 10 is set as the temporary storage layer 11, and the other layers of the three-dimensional warehouse 10 are set as the storage layers 12, enabling the three-dimensional warehouse storage system to store from above and pick from below. The transfer trolley device 40 transports materials within the temporary storage layer 11 for sorting, and the four-way vehicle transports materials within the storage layer 12 for material storage, making full use of the area occupied by the three-dimensional warehouse 10 and improving the plane utilization rate. At the same time, the transfer trolley device 40 with higher flexibility is used for material access operations in the temporary storage layer 11. For materials that still need to be picked in the next batch, instead of returning to the warehouse through the lifting device 30 and the four-way vehicle device 20, they are transported by the transfer trolley device 40 to be temporarily stored within the temporary storage layer 11, waiting for the next picking, reducing the time for inbound and outbound, and improving production efficiency.

[0056] The transfer trolley device 40 mainly has the following paths:

[0057] Path 1: The transfer trolley device 40 transports the pallet 60 carrying materials to the loading and unloading area 35 of the lifting device 30 for loading. The lifting device 30 lifts the pallet 60 carrying materials to the storage layer 12 and transfers it to the four-way vehicle device 20 within the storage layer 12. The four-way vehicle device 20 within the storage layer 12 transports the pallet 60 carrying materials to the corresponding storage location, and after completing the inbound or sorting of the materials, it returns to the warehouse for storage.

[0058] Path 2: The four-way vehicle device 20 transports the pallet 60 carrying materials within the storage layer 12 to the lifting device 30. The lifting device 30 lowers the pallet 60 carrying materials for unloading. The transfer trolley device 40 transports the pallet 60 carrying materials to the temporary storage layer 11 for outbound temporary storage.

[0059] Path 3: The transfer trolley device 40 transports the pallet 60 carrying materials from the temporary storage layer 11 to the sorting area 50. The sorting personnel sort the materials. After sorting, the system determines whether this material is still needed in the next batch. If this material is still needed, the transfer trolley device 40 transports this material to the temporary storage layer 11; if this material is no longer needed in the next batch due to model change, the transfer trolley device 40 transports this material to the lifting device 30.

[0060] Specifically, the transfer trolley device 40 can be an AGV (Automated Guided Vehicle) trolley. The AGV trolley can automatically navigate and transport materials without human intervention, reducing the need for manual operation and improving work efficiency. The AGV trolley can be flexibly adjusted according to environmental changes, adapting to different handling routes and layouts, and is particularly suitable for a dynamically changing working environment.

[0061] In the embodiment of this application, please refer to Figure 1The lifting device 30 includes an elevator 31, a first conveyor 32 and a second conveyor 33; the first conveyor 32 is arranged on the same layer as the temporary storage layer 11, and the first conveyor 32 is used to transfer the pallet 60 carrying materials on the transfer trolley device 40 to the elevator 31; the second conveyor 33 is located between the elevator 31 and the storage layer 12, and the second conveyor 33 is used to transfer the pallet 60 carrying materials on the elevator 31 to the four-way vehicle device 20.

[0062] The first conveyor 32 is arranged on the same level as the temporary storage layer 11. The first conveyor 32 is responsible for transferring the pallet 60 carrying materials from the transfer trolley device 40 to the elevator 31, and then the elevator 31 lifts the pallet 60 carrying materials to the storage layer 12. The second conveyor 33 is responsible for transferring the pallet 60 carrying materials from the elevator 31 to the four-way vehicle device 20, thereby completing the warehousing of materials or returning them to the warehouse for storage after sorting.

[0063] Among them, by setting the first conveyor 32 to dock between the elevator 31 and the transfer trolley device 40, and setting the second conveyor 33 to dock between the elevator 31 and the four-way vehicle device 20, the efficiency of conveying the pallet 60 is improved. The first conveyor 32 and the second conveyor 33 can be chain conveyors with conveying functions. The first conveyor 32 and the second conveyor 33 are other conveying structures, and the present application does not limit the specific models of the first conveyor 32 and the second conveyor 33.

[0064] The elevator 31 can be sunk to achieve a height at which the elevator 31 and the first conveyor 32 can be docked, thereby facilitating automatic docking.

[0065] In the embodiments of this application, please refer to Figure 1 The loading and unloading area 35 includes a first loading and unloading position 351 and a second loading and unloading position 352 which are respectively arranged on opposite sides of the elevator 31. The second loading and unloading position 352 is located between the elevator 31 and the temporary storage layer 11. A first conveyor 32 is arranged on the first loading and unloading position 351. The lifting device 30 also includes a third conveyor 34 located at the second loading and unloading position 352. The third conveyor 34 is used to transfer the pallet 60 carrying materials on the transfer trolley device 40 to the elevator 31.

[0066] The first loading and unloading position 351 is located on the side of the elevator 31 away from the temporary storage layer 11. The first loading and unloading position 351 is provided with a first conveyor 32. The first loading and unloading position 351 is used for direct storage of materials or storage of materials after sorting. It can be understood that the sorting area 50 can be all areas outside the stereoscopic warehouse 10.

[0067] The second loading and unloading position 352 is located between the elevator 31 and the temporary storage layer 11. A third conveyor 34 is provided at the second loading and unloading position 352. The third conveyor 34 is used to transfer the pallet 60 carrying the material from the transfer trolley device 40 to the elevator 31. After the material sorting is completed, if this material is no longer needed in the next production run due to model change, the transfer trolley device 40 transports the material to the third conveyor 34. The third conveyor 34 transfers the material to the elevator 31, and then the elevator 31 lifts the material to the storage layer 12. The second conveyor 33 transfers the material on the elevator 31 to the four-way vehicle device 20 in the storage layer 12.

[0068] Please refer to Figure 2 , the automated storage and retrieval system 10 is formed with a main passage 13 extending in the length direction and a sub-passage 14 extending in the width direction. A plurality of main passages 13 are arranged at intervals in the width direction, and a plurality of sub-passages 14 are arranged at intervals in the length direction. By providing a plurality of main passages 13 and sub-passages 14, it is convenient for the four-way vehicle device 20 and the transfer trolley device 40 to carry the pallet 60 and the material.

[0069] In the embodiment of the present application, please refer to Figure 3 , a support cantilever 112 is provided on the column 111 of the automated storage and retrieval system 10 corresponding to the temporary storage layer 11. The transfer trolley device 40 is used to drive the pallet 60 to descend so that the pallet 60 is placed on the support cantilever 112, and to lift the pallet 60 so that the pallet 60 is separated from the support cantilever 112 and drive the pallet 60 to move.

[0070] After the sorting is completed, if this material is still needed, the transfer trolley device 40 lifts the pallet 60 and drives the pallet 60 to move into the space enclosed by the support cantilever 112. Then the transfer trolley device 40 drives the pallet 60 to descend to place the pallet 60 on the support cantilever 112, and the support cantilever 112 supports the pallet 60.

[0071] In the case where this material needs to be sorted again, the transfer trolley device 40 moves into the space below this material, lifts the pallet 60 to separate the pallet 60 from the support cantilever 112, and then the transfer trolley device 40 transports the pallet 60 carrying this material to the sorting area 50 for the next sorting.

[0072] In the embodiment of the present application, the automated storage and retrieval system further includes a pallet 60. An identification code is provided at the bottom of the pallet 60. An identifier is provided at the top of the transfer trolley device 40. The transfer trolley device 40 can extend into the bottom of the pallet 60 so that the identifier can identify the identification code.

[0073] The identification code is set at the bottom of the tray 60, preventing the identification code from being damaged or soiled during transportation and storage, and ensuring the accuracy and reliability of information. The identifier is set on the top of the transfer cart device 40. When the transfer cart device 40 extends to the bottom of the tray 60, the identifier automatically scans and identifies the identification code to easily obtain information about the tray 60 and the materials on the tray 60. When the identifier successfully reads the identification code, the relevant information is transmitted to the control system in real time for subsequent logistics management and data analysis. This makes the entire material management process more intelligent and significantly improves the operation efficiency of the automated storage and retrieval system.

[0074] In the embodiment of the present application, please refer to Figure 3 , the column 111 is provided with a plurality of first fixing holes 1111 arranged at intervals in the height direction. The support cantilever 112 includes a connected mounting portion 1121 and a cantilever portion 1122. The cantilever portion 1122 extends horizontally, and the mounting portion 1121 extends vertically and both the upper and lower ends thereof extend out of the cantilever portion 1122. The mounting portion 1121 is provided with a second fixing hole 1123. The temporary storage layer 11 further includes a fastener, and the fastener sequentially passes through the second fixing hole 1123 and the first fixing hole 1111.

[0075] The cantilever portion 1122 of the support cantilever 112 extends horizontally and is used to support the tray 60. The mounting portion 1121 extends in the vertical direction, and both the upper and lower ends of the mounting portion 1121 extend out of the cantilever portion 1122. The middle position of the cantilever portion 1122 is connected to the mounting portion 1121, making the force on the mounting portion 1121 more uniform. The plurality of first fixing holes 1111 on the column 111 are arranged at intervals in the up and down direction. The mounting portion 1121 is provided with a second fixing hole 1123, and the fastener can sequentially pass through the second fixing hole 1123 and any first fixing hole 1111 to fix the mounting portion 1121 on the column 111. The fastener can be a bolt and a nut. The bolt sequentially passes through the second fixing hole 1123 and the first fixing hole 1111, and the nut is threadedly connected to the bolt. The threaded connection can achieve self-locking, making the structure more stable and reliable.

[0076] Moreover, by selecting the first fixing holes 1111 at different heights, the height position of the support cantilever 112 on the column 111 can be adjusted. Selecting the upper first fixing holes 1111 makes the distance between the support cantilever 112 and the ground farther, allowing the transfer cart device 40 with a larger height dimension to enter. Selecting the lower first fixing holes 1111 makes the distance between the support cantilever 112 and the ground closer, allowing the transfer cart device 40 with a smaller height dimension to enter.

[0077] The number of the second fixing holes 1123 can be multiple, and the number of the fasteners can also be multiple to enhance the connection strength between the mounting part 1121 and the column 111. The present application does not limit the number of the second fixing holes 1123 and the fasteners.

[0078] In the embodiment of the present application, please refer to Figure 3 , a buffer pad 113 contacting with the tray 60 is provided on the cantilever part 1122. The material of the buffer pad 113 is usually selected as plastic or rubber with high elasticity, compression resistance and good wear resistance, so as to maintain stable performance and appearance during long-term use. When the tray 60 is placed on the supporting cantilever 112, the buffer pad 113 can effectively absorb the impact force and pressure, provide the necessary buffering effect, avoid the tray 60 from being worn or scratched due to direct contact with the supporting cantilever 112, and extend the service life of the tray 60.

[0079] Specifically, the buffer pad 113 has a connected buffer part 1131 and a limiting part 1132. The buffer part 1131 is connected to the supporting cantilever 112, and the limiting part 1132 is arranged obliquely upward along the direction away from the supporting cantilever 112. The buffer part 1131 plays a buffering role, and the limiting part 1132 is used to limit the tray 60, avoid the position where the tray 60 is placed being too close to the column 111, which causes inconvenience in handling the tray 60, and improve the handling efficiency.

[0080] In the embodiment of the present application, the control system of the automated storage and retrieval system is constructed based on the logistics scheduling management control system. The logistics scheduling management control system includes a warehouse scheduling module for scheduling the four-way vehicle device 20 in the automated warehouse 10, a trolley scheduling module for scheduling the transfer trolley device 40, a production line logistics scheduling module for scheduling the materials in the automated warehouse 10, and a warehouse information management system for information management of the incoming and outgoing materials in the automated warehouse 10.

[0081] The control system of the automated storage and retrieval system is constructed based on the logistics scheduling management control system. The logistics scheduling management control system (Logistics Control System, abbreviated as LCS) is an integrated management information system, aiming to optimize each link in the logistics process, improve efficiency and reduce costs. The LCS system helps enterprises to realize real-time monitoring, analysis and decision-making support for logistics activities by integrating relevant data and information.

[0082] The warehouse scheduling module (Warehouse Control System, abbreviated as WCS) is used to schedule the four-way vehicle device 20 in the automated warehouse 10, so that the four-way vehicle device 20 transports the tray 60 carrying materials to the storage location.

[0083] The Robot Control System (RCS) is used to schedule and manage the transfer cart device 40 (AGV). After receiving instructions from the upper-level system (such as WMS / WCS), RCS dynamically allocates tasks to the AGV and optimizes the operation process. RCS dynamically plans the optimal path based on the real-time environment and adapts to complex scenarios (such as dynamic obstacles).

[0084] The Logistics Execution System (LES) is used to schedule the materials in the automated storage and retrieval system 10, overall consider the interaction of materials between different automated storage and retrieval systems 10, and realize the logistics management system for the materials from warehousing, in-warehouse management, outbound, transfer to the final assembly line. LES schedules the materials to the workstations of the corresponding assembly line according to the production order.

[0085] The Warehouse Management System (WMS) is used to manage the information of the incoming and outgoing materials in the automated storage and retrieval system 10, help the warehouse management personnel to realize the functions of accurate recording, inventory tracking and inventory scheduling of the materials in the automated storage and retrieval system 10, so as to realize the overall monitoring and management of the operation of the automated storage and retrieval system 10.

[0086] The control system of the automated storage and retrieval system can be interconnected with the manufacturing execution system at the production end and the supplier management system to ensure the automation, intelligence and wisdom of the entire supply line system.

[0087] The Manufacturing Execution System (MES) at the production end is used to formulate a reasonable production plan according to the order requirements and resource conditions, and make dynamic adjustments to ensure the smooth progress of the production process.

[0088] The Supplier Relationship Management (SRM) is used to store and centralize all supplier data, find new suppliers, create queries and identify supplier-related risks.

[0089] Provide recent production order information through the MES system. The LES system performs order PO matching based on the order information. After the order matching is completed, the LES system transfers the material requirement information to the in-plant WMS system for material availability check. If the materials are not available in full, the shortage information is transferred to the SRM system to automatically generate a purchase order for replenishment. After the purchased goods are received and stored in the warehouse, the information is transferred to the WMS system, and the WMS system updates the inventory information to complete the material availability check. According to the production order information, the WMS system generates an outbound task to the sorting area 50 for sorting and palletizing operations. Based on the production demand at the line side, the material conveying path is judged, and the AGV is called to reach different paths to ensure that the efficiency of the four-way garage can meet the usage requirements.

[0090] In addition, please refer to Figure 4 , the present invention also provides a control method for a three-dimensional warehouse storage system. The control method is applied to the three-dimensional warehouse storage system as described above, and includes:

[0091] Step S10, confirm whether the materials on the transfer cart device 40 located in the sorting area 50 need to be picked again;

[0092] The sorting personnel sort the materials. After the sorting is completed, the system confirms whether the materials are still needed in the next batch.

[0093] Step S20, if the materials need to be picked again, control the transfer cart device 40 to transfer to the temporary storage layer 11;

[0094] For the materials that still need to be picked in the next batch, they are transported by the transfer cart device 40 to be temporarily stored in the temporary storage layer 11 and wait for the next picking, instead of returning to the warehouse through the lifting device 30 and the four-way vehicle device 20, reducing the time for inbound and outbound, and improving production efficiency.

[0095] Step S30, if the materials do not need to be picked again, control the transfer cart device 40 to transfer to the loading and unloading area 35 of the lifting device 30, and control the lifting device 30 to transfer the pallet 60 carrying the materials on the transfer cart device 40 to the storage layer 12.

[0096] For the materials that do not need to be picked in the next batch, they are transported by the transfer cart device 40 to the loading and unloading area 35 of the lifting device 30, and control the lifting device 30 to transfer the materials on the transfer cart device 40 to the four-way vehicle device 20 in the storage layer 12, and the four-way vehicle device 20 transports the materials to the storage location.

[0097] In the embodiment of the present application, the control method further includes:

[0098] Step S40, when receiving the picking instruction confirmed according to the production order information, confirm whether the materials are complete;

[0099] If the parts are complete, the four-way vehicle device 20 in the warehousing layer 12 is controlled to transport the materials to the lifting device 30, and the lifting device 30 lowers the materials to the loading and unloading area 35, so that the transfer trolley device 40 transfers the materials in the loading and unloading area 35 to the sorting area 50 for sorting;

[0100] Step S50, if the parts are not complete, control the generation of a purchase order and send it to the supplier management system.

[0101] The MES system provides production order information. After the control system of the automated warehouse storage system receives the production order information, it confirms the picking instruction according to the production order information, and confirms whether the materials are complete according to the picking instruction. If the materials are complete, the four-way vehicle device 20 in the warehousing layer 12 is controlled to transport the corresponding materials to the lifting device 30, the lifting device 30 lowers the materials to the loading and unloading area 35 for unloading, and the transfer trolley device 40 transfers the materials in the loading and unloading area 35 to the sorting area 50 for sorting. After sorting, they are transported to the corresponding assembly production line. If the materials are not complete, control the generation of a purchase order and send it to the supplier management system (SRM system). After the purchased goods are received and stored in the warehouse, the inventory information is updated, and the material completeness check is performed again.

[0102] In the embodiment of the present application, the control method further includes:

[0103] When it is necessary to transfer the pallet 60 carrying materials to the warehousing layer 12, obtain the occupancy rate of each warehousing layer 12;

[0104] Control the lifting device 30 to lift the pallet 60 carrying materials to the warehousing layer 12 with the lowest occupancy rate. When the materials need to be warehoused or returned to the warehouse after sorting, it is necessary to transfer the pallet 60 carrying materials to the warehousing layer 12. Specifically, which warehousing layer 12 to transfer to requires obtaining the occupancy rate of each warehousing layer 12. The occupancy rate refers to the ratio between the used warehousing space and the total warehousing space in the warehousing layer 12. The used warehousing space is the warehousing space where materials have been stored. Controlling the lifting device 30 to lift the pallet 60 carrying materials to the warehousing layer 12 with the lowest occupancy rate and storing the materials preferentially in the warehousing layer 12 with the lowest occupancy rate can make more effective use of the warehousing space of the automated warehouse 10.
