Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation, and more specifically, to a special pallet rack for AMR (Automatic Transporter). Background Technology

[0002] In logistics and warehousing systems, traditional pallet rack designs often include top shelves. While this structure provides some protection for goods, it has significant limitations when used in conjunction with AMRs (Autonomous Mobile Robots). Especially when AMRs frequently need to move materials between pallet racks and picking stations, the top shelves not only increase the overall cost of the pallet rack but also require additional steps to handle empty pallets during inbound and outbound operations, thus reducing operational flexibility and efficiency. During material handling, AMRs need to shuttle between pallet racks and picking stations while empty, wasting valuable operating time and indirectly increasing the number of robots deployed to compensate for the inefficiency.

[0003] There is currently no effective solution to the above problems. Utility Model Content

This solves the problems of low working efficiency and poor stability of the traditional docking method in the prior art. Attached Figure Description

[0045] In logistics warehousing systems, the top shelf design of traditional pallet racks does provide some protection for stored items. However, this seemingly comprehensive protection has shown significant disadvantages and limitations in actual operation, especially in scenarios where it works in collaboration with AMRs (Autonomous Mobile Robots). Specifically, the presence of the top shelf has the following negative impacts on the operation process and cost-effectiveness of AMRs:

[0046] When AMR robots are used for material handling in and out of warehouses, the top shelves of traditional pallet racks become an obstacle. During material receiving, the robot must first handle empty pallet racks, transporting them from the storage area to the picking or loading station; then, after material retrieval, i.e., after picking, the AMR faces the task of returning empty pallet racks to the storage area. This additional back-and-forth motion not only consumes a significant amount of the robot's time, reducing the continuity and efficiency of its task execution, but also poses greater challenges to robot scheduling and path planning, requiring more complex algorithms to ensure the robot can flexibly switch between multiple tasks without causing congestion or waiting.

[0047] The design of the top cover increases the manufacturing cost of the pallet rack. This additional cost is reflected not only in the materials used but also in the labor and time costs during production and assembly. Furthermore, considering the potential maintenance and replacement needs of the top cover, long-term maintenance costs will also increase accordingly. In addition, the weight of the top cover increases the overall load on the pallet rack, meaning that in some cases, the AMR robot needs greater power output or a more robust structural design to cope, further driving up the overall system cost.

[0048] Due to the aforementioned inefficiencies, companies often have to increase the number of AMR robots deployed in order to maintain the material flow speed and overall work efficiency within the logistics and warehousing system. More robots mean higher capital investment, more complex management and scheduling systems, and potentially increased energy consumption. While this increase in indirect costs may alleviate operational efficiency issues in the short term, in the long run, it will exacerbate the operational pressure on the warehousing system and may bring a series of new challenges such as equipment overcrowding and increased robot collision risks.

[0049] Combination Figures 1 to 5 As shown, according to a specific embodiment of this application, a dedicated tray rack for AMR is provided.

[0050] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, an AMR-specific pallet rack includes: a longitudinal beam 10, the longitudinal beam 10 including: a first inclined plate assembly 50, a horizontal plate 103, and a second inclined plate assembly 60. One end of the first inclined plate assembly 50 is connected to the first end of the horizontal plate 103, and the first inclined plate assembly 50 and the horizontal plate 103 are arranged at a preset angle. The second end of the horizontal plate 103 is connected to one end of the second inclined plate assembly 60, and the horizontal plate 103 and the second inclined plate assembly 60 are arranged at a preset angle. The first inclined plate assembly 50 and the second inclined plate assembly 60 are spaced apart, and the first inclined plate assembly 50 and the second inclined plate assembly 60 are... A contraction space 100 is formed between the two inclined plate assemblies 60; there are multiple crossbeam assemblies 20, which are spaced apart along a first preset direction and are located below the longitudinal beam 10. The multiple crossbeam assemblies 20 are movably connected to the cross plate 103, and are arranged at a preset angle with the first inclined plate assembly 50 and the second inclined plate assembly 60, respectively; wherein, at least two adjacent crossbeam assemblies 20 and the longitudinal beam 10 form a carrying space for carrying goods.

[0051] By applying the technical solution of this utility model, a frame structure composed of longitudinal beams 10 and crossbeam assemblies 20 is adopted, eliminating the top cover plate. Through the specific connection method of longitudinal beams 10 and crossbeam assemblies 20, this design can not only ensure the safe storage of goods, but also significantly reduce the working time of robots under no-load conditions, thereby improving the overall operating efficiency of the logistics warehousing system and solving the problems of low working efficiency and poor stability of traditional docking methods in the prior art.

[0052] Furthermore, the AMR dedicated pallet rack also includes: a support plate 40, which includes multiple support plates 40, which are spaced apart along a first preset direction, and a support plate 40 is provided between at least two adjacent crossbeam assemblies 20, and the multiple support plates 40 are respectively connected to the cross plate 103.

[0053] In this embodiment, multiple support plates 40 are arranged at intervals along a first preset direction and cleverly connected between at least two adjacent crossbeam assemblies 20. This design not only improves the support effect of the crossbeam assemblies 20 and effectively distributes the load, avoiding deformation or damage caused by excessive load on a single crossbeam, but also constructs a more robust and reliable load-bearing platform through close connection with the cross plate 103. The addition of the support plates 40 not only ensures the safety performance of the pallet rack under high loads, but also optimizes the material loading and unloading process, reduces potential risks to AMR robots during operation, and achieves a dual improvement in the efficiency and safety of the logistics warehousing system.

[0054] In this embodiment, the AMR dedicated pallet frame further includes: support beams 30, including multiple support beams 30, each of which is correspondingly arranged with a multiple crossbeam assembly 20, one end of each of the multiple support beams 30 is connected to the corresponding crossbeam assembly 20, the multiple support beams 30 are located below the longitudinal beam 10, and the multiple support beams 30 are spaced apart from the longitudinal beam 10.

[0055] By applying this embodiment, the support beam 30 can effectively share the weight borne by the crossbeam assembly 20. Simultaneously, through its indirect connection with the longitudinal beam 10, it further strengthens the basic frame of the entire pallet rack, improving the structure's rigidity and resistance to deformation. Furthermore, the spacing between the support beam 30 and the longitudinal beam 10 not only enhances ventilation and light penetration within the pallet rack but also facilitates accurate identification and positioning by the AMR robot, significantly improving the pallet rack's applicability and operational efficiency in automated logistics scenarios.

[0056] Specifically, such as Figure 4 As shown, at least one of the plurality of crossbeam assemblies 20 includes: a crossbar 202, which is connected to the cross plate 103, and is respectively set at a preset angle with the first inclined plate assembly 50 and the second inclined plate assembly 60; the crossbar 202 is connected to a corresponding support beam 30 among the plurality of support beams 30, and is set at a preset angle with the corresponding support beam 30 among the plurality of support beams 30; and a first support rod 201, one end of which is connected to the first end of the crossbar 202. The first support rod 201 is set at a preset angle to the crossbar 202, and is spaced apart from the longitudinal beam 10 and the support beam 30 respectively; the second support rod 203 has one end connected to the second end of the crossbar 202, and is set at a preset angle to the crossbar 202. The second support rod 203 is spaced apart from the support beam 30, the longitudinal beam 10 and the first support rod 201 respectively, and the corresponding support beam 30 among the multiple support beams 30 is located between the first support rod 201 and the second support rod.

[0057] In this embodiment, the crossbar 202, the first support rod 201, and the second support rod 203 are integrated to form a stable and efficient support structure. The crossbar 202, as the core component of the beam assembly 20, is not only tightly connected to the cross plate 103, ensuring the flatness and strength of the pallet rack platform, but also set at a preset angle with the first inclined plate assembly 50 and the second inclined plate assembly 60. This angle design facilitates stable placement of goods and precise docking of the AMR robot. More importantly, the crossbar 202 is also connected to the corresponding support beam 30 at a preset angle. This angle setting not only enhances the stability of the structure but also allows the crossbar 202 to better distribute the load, reducing stress concentration and improving the overall load-bearing capacity of the pallet rack. The first support rod 201 and the second support rod 203 are connected to both ends of the crossbar 202, respectively. They maintain a certain distance from the crossbar 202, the longitudinal beam 10, and the support beam 30. This layout not only enhances the structural rigidity of the beam assembly 20 but also prevents the pallet rack from deforming under heavy loads.

[0058] In an exemplary embodiment, at least one of the first inclined plate assembly 50 and the second inclined plate assembly 60 includes: a vertical plate 102, which is disposed at a predetermined angle to the horizontal plate 103, and a first end of the vertical plate 102 is connected to one end of the horizontal plate 103; and a transition plate assembly 101, which is disposed at one end to the second end of the vertical plate 102, and is spaced apart from the horizontal plate 103, and is disposed at a predetermined angle to the vertical plate 102.

[0059] In this embodiment, the vertical plate 102 and the horizontal plate 103 are connected at a preset angle, ensuring a smooth transition from the ground to the pallet rack platform. The first end of the vertical plate 102 is firmly connected to one end of the horizontal plate 103, forming a stable support surface. The addition of the transition plate assembly 101 cleverly connects the second end of the vertical plate 102 to the horizontal plate 103, maintaining a distance from the horizontal plate 103 to avoid structural interference that may be caused by direct contact.

[0060] Specifically, such as Figure 5As shown, the transition plate assembly 101 includes: a first connecting segment 405, the first end of which is connected to the second end of the vertical plate 102, and the first connecting segment 405 and the vertical plate 102 are arranged at a preset angle; a second connecting segment 404, the first end of which is connected to the second end of the first connecting segment 405, and the second connecting segment 404 is spaced apart from the vertical plate 102, and the second connecting segment 404 and the first connecting segment 405 are arranged at a preset angle; and a third connecting segment 403, the first end of which is connected to the second end of the second connecting segment 404, and the third connecting segment 403 and the second connecting segment 404 are arranged at a preset angle, and the third connecting segment 403 is connected to the first connecting segment 105 at the second end of the vertical plate 102 ... Connecting segment 405 and vertical plate 102 are spaced apart; fourth connecting segment 402, the first end of the fourth connecting segment 402 is connected to the second end of the third connecting segment 403, the fourth connecting segment 402 and the third connecting segment 403 are set at a preset angle, and the fourth connecting segment 402 is spaced apart from the second connecting segment 404, the first connecting segment 405 and the vertical plate 102 respectively; fifth connecting segment 401, the first end of the fifth connecting segment 401 is connected to the second end of the fourth connecting segment 402, the fifth connecting segment 401 and the fourth connecting segment 402 are set at a preset angle, and the fifth connecting segment 401 is spaced apart from the third connecting segment 403, the second connecting segment 404, the first connecting segment 405 and the vertical plate 102 respectively.

[0061] In this embodiment, the first connecting segment 405 is directly connected to the second end of the vertical plate 102 and is tilted at a specific angle, providing an initial transition from the vertical plate to the horizontal plane. Subsequently, the second connecting segment 404 connects to the second end of the first connecting segment 405, maintaining a distance from the vertical plate 102, ensuring smooth and unobstructed movement of the robot. The third connecting segment 403, the fourth connecting segment 402, and the fifth connecting segment 401 are connected in sequence, each segment maintaining a preset angle with the previous segment, while maintaining a distance from the vertical plate 102 and the preceding connecting segment, forming a progressive transition ramp. This allows the AMR robot to smoothly and stably enter and exit the pallet rack, avoiding the positioning inaccuracies and collision risks that may be caused by the traditional right-angle entry and exit method.

[0062] Furthermore, the fifth connecting segment 401 is arranged parallel to the third connecting segment 403. The parallel structure ensures a smooth transition from the ramp to the final horizontal docking area. The fifth connecting segment 401, as the last transition path before the AMR robot reaches the top of the pallet rack, remains parallel to the third connecting segment 403, together forming a wide and stable docking surface.

[0063] In this embodiment, the fourth connecting segment 402 is arranged parallel to the second connecting segment 404. The parallel arrangement of the fourth connecting segment 402 and the second connecting segment 404 forms a smooth transition channel with a consistent width. This not only helps the robot maintain a straight line during ascent or descent, avoiding operational errors caused by path changes, but also ensures the smoothness of the robot's movement and reduces vibrations or speed fluctuations that may be caused by changes in slope.

[0064] Specifically, at least one of the fourth connecting segment 402 and the second connecting segment 404 is arranged parallel to the vertical plate 102. The parallel arrangement of the connecting segments with the vertical plate provides clear guidance for the robot as it approaches the storage location, reducing positional errors during alignment and enhancing operational accuracy and efficiency. In particular, when the second connecting segment 404 is parallel to the vertical plate 102, it serves as the starting segment transitioning from a ramp to a gentle path, ensuring the robot smoothly transitions from an inclined to a horizontal position, avoiding instability caused by sudden path changes. When the fourth connecting segment 402 is parallel to the vertical plate, it serves as the terminal section of the transition path, providing the robot with a stable and open final alignment area, facilitating fine-tuning before entering the storage location and ensuring precise docking.

[0065] In one exemplary embodiment, the first connecting segment 405 extends into the retractable space 100. This allows the first connecting segment 405 to better conform to the edge of the pallet rack and extend into a gradually narrowing space, effectively guiding the robot smoothly from a more open area to the narrow docking area. By extending inward, the first connecting segment 405 not only reduces obstacles the robot may encounter upon entry but also provides more precise directional guidance, reducing alignment difficulty. This design is particularly beneficial for achieving efficient logistics operations in limited spaces, ensuring good guidance for the robot from the moment it begins contacting the transition plate assembly, thereby ensuring the smoothness and safety of the entire handling process.
