Description

Technical Field

[0001] This invention belongs to the field of prefabricated building warehousing and logistics technology, and in particular relates to a three-dimensional warehouse system for storing and sorting prefabricated building decoration raw materials. Background Technology

[0002] In the production process of prefabricated building decoration components, raw material warehousing management is a key link connecting prefabrication and on-site assembly. Currently, the industry commonly uses high-rise automated warehouses (AS / RS) as transit and buffer units to automate the supply of decoration raw materials from suppliers to production line workstations. These AS / RS typically consist of racking systems, stacker cranes or shuttle cars, and a warehouse management system (WMS). Through preset storage code and aisle operation logic, they complete the automatic inbound and outbound of raw materials and inventory management.

[0003] However, existing automated warehouse (AS / RS) storage compartments are mostly designed with fixed spacing and uniform height, capable of holding only one or two industry-standard pallets. When incoming materials involve multiple pallet sizes, they can only be simply mixed together in the same compartment. This mixed placement not only disrupts the WMS's preset compartment logic but also requires manual intervention for confirmation in every inbound and outbound operation, significantly reducing the continuity of automated operations. Furthermore, due to the mixed pallet sizes, sensor signals detecting the outlines of goods often misinterpret or overlap, causing the system-recorded storage location coordinates to deviate from the actual physical location. This leads to difficulties in raw material traceability and discrepancies between inventory records and actual stock, forcing companies to conduct frequent full inventory checks, consuming significant manpower and time.

[0004] Furthermore, if the pallets delivered to the automated storage and retrieval system (AS / RS) are too high, they are highly susceptible to mechanical interference with the upper-level equipment. This can range from minor scratches and damage to packaging to more serious issues such as deformation of the stacker crane forks or even rack collapse, posing a significant safety hazard. Therefore, existing AS / RS systems are no longer adequate for the current needs of the prefabricated building decoration industry for flexible and intelligent warehousing. Summary of the Invention

[0005] (a) Technical problems to be solved In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an automated warehouse system for storing and sorting prefabricated building decoration raw materials, thereby solving the technical problem that insufficient pallet compatibility affects storage efficiency and even poses a potential production safety hazard.

[0006] (II) Technical Solution To achieve the above objectives, the main technical solutions adopted by the present invention include: This invention provides an automated warehouse system for storing and sorting prefabricated building decoration raw materials, including racks and a stacker crane system. The racks include at least one first rack, at least one second rack, and at least one third rack. The automated warehouse system also includes a first pallet, an A-bracket pallet, a second pallet, and a third pallet with successively decreasing lengths and uniform widths. The height of the A-bracket pallet is greater than the height of the first, second, and third pallets. The dimensions of the first rack are adapted to accommodate the first pallet, the dimensions of the second rack are adapted to accommodate the A-bracket pallet, and the dimensions of the third rack are adapted to accommodate either the second or third pallet. The stacker crane system includes a stacker crane, which is movable along the extension direction of the racks. The movement space of the stacker crane forms an aisle, and the racks are arranged on both sides of the aisle. The stacker crane is equipped with multiple independently telescopic forks arranged in parallel, and the span of the extended forks is adapted to the length of the first, A-bracket, second, and third pallets.

[0007] Furthermore, one end of the shelf has two rows of first shelves, the other end of the shelf has one row of first shelves, the other end of the shelf has one row of second shelves adjacent to the first shelves, and the middle of the shelf between the two ends has multiple rows of third shelves.

[0008] Furthermore, the automated warehouse system also includes a first pallet, a second pallet, and a third pallet. The first pallet includes a first pallet body, and the first pallet includes a first pallet body and a first perimeter fence surrounding the first pallet body. The A-frame pallet includes a second pallet body and an A-frame on the second pallet body. The second pallet includes a second pallet body, and the second pallet includes a second pallet body and a second perimeter fence surrounding the second pallet body. The third pallet includes a third pallet body, and the third pallet includes a third pallet body and a third perimeter fence surrounding the third pallet body. The dimensions of the first storage compartment are also adapted to accommodate the first pallet, and the dimensions of the third storage compartment are also adapted to accommodate the second or third pallet.

[0009] Furthermore, the shelving system comprises three levels along its height, which can be aligned with the heights of the first, second, and third floors of the factory building, respectively. The first floor, on the side furthest from the factory building, has a first, second, and third entry point. The first entry point is for the first pallet and first material frame; the second entry point is for the A-bracket pallet, the second pallet, and the second material frame; and the third entry point is for the third pallet and the third material frame. The first, second, and third floors, on the side closest to the factory building, each have a first exit point. The second and third exit ports are as follows: the first exit port is used for the first pallet and the first material frame to exit; the second exit port is used for the A-bracket pallet, the second pallet, and the second material frame to exit; and the third exit port is used for the third pallet and the third material frame to exit. The first, second, and third entry ports, the first, second, and third exit ports on the first floor of the racking are used to connect with AGVs for automated inbound and outbound operations. The first, second, and third exit ports on the second and third floors of the racking are used to connect with forklifts for outbound operations.

[0010] Furthermore, a first pallet unpacking machine is installed on one side of the first inbound and first outbound entrances, a second pallet unpacking machine is installed on one side of the second inbound and second outbound entrances, and a third pallet unpacking machine is installed on one side of the third inbound and third outbound entrances. AGVs automatically dock with the first, second, and third pallet unpacking machines on the first floor of the racking system to complete outbound or return operations, while forklifts automatically dock with the first, second, and third pallet unpacking machines on the second and third floors of the racking system to complete outbound or return operations.

[0011] Furthermore, the first, second, and third floors of the racking system are equipped with picking loops on the side closest to the factory building, which are shared by the third pallet and the third material box. The stacker crane is slidably installed on the ground rail in the stacker crane pit, allowing the stacker crane to move laterally along the ground rail. The stacker crane pit is 600-1000mm lower than the ground. The first-level picking height of the racking system is 200-600mm, which is consistent with the height of the worker's platform next to the picking loop.

[0012] Furthermore, the stacker crane also includes a loading platform and columns located at both ends of the loading platform. The loading platform and the columns are slidably connected, allowing the loading platform to move up and down along the columns, and the columns to move laterally along the ground rails. Multiple forks are located at the bottom of the loading platform and are symmetrical about the center line of the loading platform.

[0013] Furthermore, the first, second, and third inbound ports, the first, second, and third outbound ports, as well as the outbound and return ports of the picking loop, are all equipped with ground scales, shape inspection stations, and barcode readers. This ensures that the raw materials carried by the first pallet, first material frame, A-bracket pallet, second pallet, second material frame, third pallet, and third material frame during inbound and outbound operations, as well as during outbound and return operations of the picking loop, all meet the rated load and dimensions of the corresponding storage compartment.

[0014] Furthermore, the dimensions of the third storage compartment are capable of accommodating two third pallets and / or third material frames; when the first third pallet and / or third material frame carries raw materials into the third storage compartment, the weight is identified by a ground scale, and it is determined that the weight of the raw materials carried by the second third pallet and / or third material frame is less than or equal to the difference between the rated load of the third storage compartment and the weight of the raw materials carried by the first third pallet or third material frame.

[0015] Furthermore, the shelves on both sides of the aisle are arranged in two rows. The row of shelves closer to the aisle is used to place high-frequency raw materials, while the row of shelves further away from the aisle is used to place low-frequency raw materials.

[0016] (III) Beneficial Effects The beneficial effects of this invention are: This invention discloses an automated warehouse system for storing and sorting prefabricated building decoration raw materials. It incorporates racking and a stacker crane system. The racking includes at least one row of first, second, and third storage compartments of different sizes, along with matching first, A-frame, second, and third pallets. The A-frame pallets are taller than the first, second, and third pallets, and are thus housed as a separate second storage compartment. The stacker crane system includes a stacker crane with multiple independently extendable forks arranged in parallel. The span of the extended forks is adapted to the lengths of the first, A-frame, second, and third pallets. Compared to existing technologies, this system allows for the use of different storage compartments to accommodate multiple pallet sizes. Furthermore, the A-frame pallets are suitable for storing extra-tall raw materials, enabling high-level isolated storage to avoid interference and ensure safety during high-level operations. Correspondingly, the stacker crane can transport pallets of various sizes, covering all specifications of decoration raw materials, demonstrating strong adaptability. Attached Figure Description

Detailed Implementation

[0019] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0020] like Figure 1-13 As shown, this invention provides an automated warehouse system for storing and sorting raw materials for prefabricated building decoration, such as... Figure 1 As shown, the system includes a rack 110, a stacker crane system 120, a first pallet 1301, a first storage rack 1305, an A-bracket pallet 1302, a second pallet 1303, a second storage rack 1306, a third pallet 1304, and a third storage rack 1307. The rack 110 includes at least one row of first storage racks 1101, at least one row of second storage racks 1102, and at least one row of third storage racks 1103. Pallets are typically used to carry goods weighing over 1 ton or with a large volume, as well as raw materials that will not scatter during transport and palletized raw materials. Storage racks are typically used to carry small to medium-sized, lighter goods or parts, generally weighing less than 25 kg, as well as raw materials that are easily scattered during transport.

[0021] like Figure 7-13 As shown, the lengths of the first pallet 1301, the A-bracket pallet 1302, the second pallet 1303, and the third pallet 1304 decrease sequentially while their widths are the same. The height of the A-bracket pallet 1302 is greater than the heights of the first pallet 1301, the second pallet 1303, and the third pallet 1304, which is suitable for high-quality raw materials.

[0022] Specifically, the first pallet 1301 includes a first pallet body 13011, the first material frame 1305 includes the first pallet body 13011 and a first enclosure net 13051 surrounding the first pallet body 13011, the A-bracket pallet 1302 includes a second pallet body 13021 and an A-bracket 13022 disposed on the second pallet body 13021, the second pallet 1303 includes the second pallet body 13021, the second material frame 1306 includes the second pallet body 13021 and a second enclosure net 13061 surrounding the second pallet body 13021, the third pallet 1304 includes the third pallet body 13041, and the third material frame 1307 includes the third pallet body 13041 and a third enclosure net 13071 surrounding the third pallet body 13041.

[0023] In this embodiment, the height of the shelf 110 is 3800-4000mm, the length of the first pallet 1301 is 3650±100mm, the width is 1250±100mm, and the height is 175±100mm, the length of the A-bracket pallet 1302 is 2450±100mm, the width is 1250±100mm, and the height is 2385±100mm, the length of the second pallet 1303 is 2450±100mm, the width is 1250±100mm, and the height is 175±100mm, the length of the third pallet 1304 is 1250±100mm, the width is 1250±100mm, and the height is 175±100mm, and the height of the first fence 13051, the second fence 13061, and the third fence 13071 are all 1100±100mm.

[0024] The first storage compartment 1101 is sized to accommodate a first pallet 1301 and a first material frame 1305. One first storage compartment 1101 can hold only one first pallet 1301 or one first material frame 1305. The second storage compartment 1102 is sized to accommodate an A-bracket pallet 1302. Only one second storage compartment 1102 can hold only one A-bracket pallet 1302, isolating the highest A-bracket pallet 1302 within a row of storage compartments as a dedicated high-level storage compartment to avoid interference with upper-level equipment. The third storage compartment 1103 is sized to accommodate a second pallet 1303, a third pallet 1304, a second material frame 1306, or a third material frame 1307. One third storage compartment 1103 can hold only one second pallet 1303 or one second material frame 1306, or two third pallets 1304 or two third material frames 1307.

[0025] It should be noted that the number of the first pallet 1301, the second pallet 1303 and the third pallet 1304 placed in the first storage compartment 1101 and the third storage compartment 1103 respectively is calculated horizontally. Multiple pallets can be stacked vertically to save storage compartments.

[0026] Preferably, such as Figure 1As shown, one end of the rack 110 has two rows of first storage compartments 1101, and the other end of the rack 110 has one row of first storage compartments 1101. The other end of the rack 110 has a row of second storage compartments 1102 located adjacent to the first storage compartments 1101. Multiple rows of third storage compartments 1103 are arranged in the middle of the rack 110 between the two ends. Because the stacker crane 1201 needs to move to the center of the storage compartment when retrieving goods to ensure stable pallet / frame loading, when the stacker crane 1201 wants to retrieve a pallet / frame from a storage compartment at the end of the rack 110, it will move a portion of the rack 110 to align with the center of the storage compartment. The greater the length of the storage compartments at both ends of the rack 110, the smaller the portion of the stacker crane 1201 moves out of the rack 110. Therefore, the ground rail 1203 under the stacker crane 1201 can be shortened. Thus, the first storage compartments 1101 are arranged at the ends of the rack 110.

[0027] The rated load capacity of the first storage compartment 1101, the second storage compartment 1102, the third storage compartment 1103, the first pallet 1301, the first material frame 1305, the A-bracket pallet 1302, the second pallet 1303, the second material frame 1306, the third pallet 1304, and the third material frame 1307 is 3 tons.

[0028] In this embodiment, the first tray 1301 can store boards and pipes, the A-bracket tray 1302 can store ultra-high aluminum windows, the second tray 1303 can store boards and stone, and the third tray 1304 can store tiles and toilets.

[0029] It should be noted that ultra-high aluminum windows can only be stored using A bracket tray 1302, while the storage type of other raw materials can be adjusted as needed.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the stacker crane system 120 includes a stacker crane 1201, which is slidably installed on a ground rail 1203 in a stacker crane pit 1202, allowing the stacker crane 1201 to move laterally along the ground rail 1203. The stacker crane 1201 is moved along the extension direction of the rack 110, and the movement space of the stacker crane 1201 forms an aisle 140. The rack 110 is arranged on both sides of the aisle 140.

[0031] Preferably, in order to improve storage density and access efficiency, the shelving 110 is designed as a double-deep unit, that is, the shelving 110 on both sides of the aisle 140 is provided with two rows. Among them, the row of shelving 110 closer to the aisle 140 is used to place high-frequency raw materials, and the row of shelving 110 further away from the aisle 140 is used to place low-frequency raw materials, so that the two rows can be coordinated and scheduled.

[0032] like Figure 1-3 , Figure 5-6As shown, the stacker crane 1201 includes a loading platform 12012, uprights 12013 located at both ends of the loading platform 12012, and multiple independently telescopic forks 12011 arranged side-by-side at the bottom of the loading platform 12012. The loading platform 12012 is slidably connected to the uprights 12013, allowing the loading platform 12012 to move up and down along the uprights 12013, and the uprights 12013 to move laterally along the ground rail 1203. The multiple forks 12011 are axially symmetrical about the centerline of the loading platform 12012, and the span of the extended forks 12011 can be adapted to the lengths of the first pallet 1301, the A-bracket pallet 1302, the second pallet 1303, and the third pallet 1304.

[0033] To improve the efficiency of material dispatching, shelving 110 is designed with independent inbound and outbound access at different levels. Specifically, as follows... Figure 2-3 , Figure 5 As shown, the shelving 110 includes three floors along its height, which can be aligned with the heights of the first floor 210, second floor 220, and third floor 230 of the factory building 200, respectively. The first floor of the shelving 110, on the side furthest from the factory building 200, has a first entry port 1501, a second entry port 1502, and a third entry port 1503, each extending into the interior of the shelving 110 with its own independent transport channel. The first entry port 1501 is used for storing the first pallet 1301 and the first material frame 1305; the second entry port 1502 is used for storing the A-bracket pallet 1302, the second pallet 1303, and the second material frame 1306; and the third entry port 1503 is used for storing the third pallet 1304 and the third material frame 1307.

[0034] On the first, second, and third floors of shelving 110, near the factory 200, there are a first outbound port 1504, a second outbound port 1505, a third outbound port 1506, and a picking loop 180. The first outbound port 1504 is used for the first pallet 1301 and the first material frame 1305. The second outbound port 1505 is used for the A-bracket pallet 1302, the second pallet 1303, and the second material frame 1306. The third outbound port 1506 is used for the third pallet 1304 and the third material frame 1307. The picking loop 180 is shared by the third pallet 1304 and the third material frame 1307 for high-frequency, rapid picking of small items, improving efficiency.

[0035] A first pallet unpacking machine 1701 is installed on one side of the first inbound port 1501 and the first outbound port 1504; a second pallet unpacking machine 1702 is installed on one side of the second inbound port 1502 and the second outbound port 1505; and a third pallet unpacking machine 1703 is installed on one side of the third inbound port 1503 and the third outbound port 1506. The first pallet unpacking machine 1701, the second pallet unpacking machine 1702, and the third pallet unpacking machine 1703 are used to unpack the first pallet 1301, the second pallet 1303, and the third pallet 1304 into individual pallets before they are stacked and after they are received with raw materials.

[0036] The first inbound port 1501, second inbound port 1502, third inbound port 1503, first outbound port 1504, second outbound port 1505, and third outbound port 1506 on the first floor of rack 110 all utilize AGVs for automated operations. The process is as follows: For empty pallets, the AGVs automatically connect to the first pallet unpacking / stacking machine 1701, second pallet unpacking / stacking machine 1702, and third pallet unpacking / stacking machine 1703 on the first floor of rack 110 to complete the empty pallet's inbound or outbound operation. For raw materials, the AGVs transport the raw materials from the inbound port to the transport channel, or the AGVs transport the raw materials from the conveyor to the outbound port to the production line.

[0037] On the second and third floors of rack 110, the first exit gate 1504, the second exit gate 1505, and the third exit gate 1506 are all operated manually using forklifts. The process is as follows: for empty pallets, the forklifts connect to the first pallet destacking machine 1701, the second pallet destacking machine 1702, and the third pallet destacking machine 1703 on the second and third floors of rack 110 to complete the empty pallet exit. For raw materials, the forklifts transport the raw materials, which are conveyed to the exit gates, to the production line side.

[0038] It should be noted that both the inbound and outbound ports are capable of returning to the warehouse.

[0039] Since the height of the stacker crane 1201 matches the first-level picking height of the rack 110, in order to allow for temporary picking by workers next to the picking loop 180, the stacker crane pit 1202 is sunken by 600-1000mm relative to the ground, so that the first-level picking height of the rack 110 is 200-600mm, which is consistent with the height of the worker's platform next to the picking loop 180, so as to meet the needs of direct manual picking.

[0040] It should be noted that the first-level retrieval height of shelf 110 is the height after the pallet is placed on the first-level shelf.

[0041] To ensure accurate and traceable inventory, such as Figure 4As shown, the first inbound port 1501, the second inbound port 1502, the third inbound port 1503, the first outbound port 1504, the second outbound port 1505, the third outbound port 1506, and the outbound and return ports of the picking loop 180 are all equipped with a ground scale 1901 for weighing, an external inspection station 1902 for detecting dimensions, and a barcode reader 1903 for verifying whether the barcode information of the materials and pallets / frames is consistent. This ensures that when the first pallet 1301, the first frame 1305, the A-bracket pallet 1302, the second pallet 1303, the second frame 1306, the third pallet 1304, and the third frame 1307 are put into and out of the warehouse, and when the picking loop 180 is put out of and returns to the warehouse, they undergo triple verification of weighing, external inspection, and barcode verification. This ensures that the raw materials carried meet the rated load and dimensions of the corresponding storage compartment, greatly improving safety. Furthermore, when the first third pallet 1304 and / or third material frame 1307 carries raw materials into the third storage compartment 1103, the weighbridge 1901 identifies the weight and determines that the weight of the raw materials carried by the second third pallet 1304 and / or third material frame 1307 entering the third storage compartment 1103 is less than or equal to the difference between the rated load capacity of the third storage compartment 1103 and the weight of the raw materials carried by the first third pallet 1304 or third material frame 1307. For example, when a third storage compartment 1103 receives a third pallet 1304 or third material frame 1307 carrying 2 tons of raw materials, the remaining space in the third storage compartment 1103 can only hold raw materials weighing ≤1 ton from the third pallet 1304 or third material frame 1307, to prevent the raw material load in the third storage compartment 1103 from exceeding 3 tons.

[0042] It should be noted that the third pallet 1304 or the third material frame 1307 of the first warehouse third storage compartment 1103 can be used as long as it does not exceed its own load capacity of 3 tons.

[0043] In addition, the automated warehouse system also includes a WMS (Logistics Management System) and a WCS (Logistics Control System). The WMS is used to store raw material information identified by the weighbridge 1901, the shape inspection station 1902, and the barcode reader 1903. The WCS is used to schedule raw materials based on the information in the WMS.

[0044] In summary, this invention is an automated three-dimensional warehouse system compatible with the first pallet 1301, the first material frame 1305, the A-bracket pallet 1302, the second pallet 1303, the second material frame 1306, the third pallet 1304, and the third material frame 1307. It adopts a high-level storage compartment isolation, double-deep racks 110, a sunken design of the stacker crane pit 1202, mixed scheduling of AGVs on the first floor and forklifts on the second and third floors, independent entry and exit of different layers, inbound and outbound weighing, external inspection, and barcode verification. It is suitable for large-scale, multi-specification, heavy-load intelligent storage and sorting scenarios of prefabricated building decoration raw materials.

[0045] Workflow 1. Warehousing process S1: Empty pallets / frames are transported from the stacker crane 1201 to the first floor via a conveyor, and then transferred by AGV to the corresponding destacking machine for destacking.

[0046] S2: The AGV delivers a single empty pallet / frame to the inbound buffer area, where the decoration raw materials are manually loaded and the barcode information of the raw materials and the pallet / frame is bound.

[0047] S3: The AGV transports the raw materials to the corresponding warehouse entrance on the first floor. The ground scale 1901, appearance inspection station 1902, and barcode reader 1903 at the warehouse entrance weigh, inspect, and verify the barcodes.

[0048] S4: After the inspection is passed, stacker crane 1201 will put the raw materials into the corresponding storage compartment.
