Abstract
Description
Technical Field
[0001] The present application relates to the field of logistics and warehousing technology, and in particular to a cargo grid unit and a shelf for a shuttle vehicle vertical warehouse system. Background Art
[0002] In the intelligent logistics storage solution with shuttle vehicles as the main body, the shuttle vehicle warehouse system is the core of the entire solution, and the structural characteristics of the shelves are related to the operating effect of the entire system.
[0003] Currently, shuttles access bins on shelves by pushing and pulling with gripping forks. Generally speaking, only when the bins are positioned correctly can the shuttles successfully complete the access operation. However, if the bins become misaligned, the shuttles can malfunction. These failures often require manual intervention to reset, making them inconvenient. Furthermore, these failures can easily damage the bins, shuttles, or shelves.
[0004] There are two main reasons for inaccurate bin positioning: inaccurate initial placement of the bins; and the inherent issues with the shuttle rack system itself. While there are many other factors contributing to inaccurate bin positioning, the most common are poor installation accuracy of the racks in the shuttle rack system or an ineffective guide mechanism. This can cause the racks to vibrate during operation, leading to misalignment of the bins. Furthermore, this misalignment can be exacerbated if the bins are lightweight, have been unsorted, or have not been shipped out for extended periods. Summary of the Invention

[0036] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0037] The embodiment of the present application provides a cargo grid unit and a shelf of a shuttle vehicle vertical warehouse system, which can correct the posture of the material box 8 to a certain extent, and can also effectively solve the problem of the material box 8 being offset on the vertical warehouse shelf.
[0038] Reference Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the material box 8 being placed on the cargo grid unit 9 in the embodiment of the present application. Figure 2 for Figure 1 Side view of the middle cargo grid unit 9. Figure 1 and Figure 2 As shown, in one embodiment, the cargo grid unit 9 includes two support beams 1 arranged in parallel, which serve as the main support of the material box 8 and bear the entire weight of the material box 8. The length direction of the two support beams 1 is also the direction in which the material box 8 enters and exits. The front ends of the two support beams 1 are installed with front connecting rods 2, and the rear ends of the two support beams 1 are installed with rear connecting rods 3. The support beams 1 are all connected to the front connecting rods 2 and the rear connecting rods 3 by snapping, and the top surface height of the support beams 1 is lower than the top surface height of the rear connecting rods 3. The cargo grid unit 9 also includes a limiting structure 4, which is arranged on the outer side surface of each support beam 1 along the length direction of each support beam 1 (which is also the direction in which the material box 8 enters and exits), and the height of the limiting structure 4 is higher than that of the support beam 1.
[0039] The two support beams 1 are mounted with front links 2 at their front ends and rear links 3 at their rear ends, forming a rectangular shape (other shapes are possible depending on the shape of the material bin 8). The support beams 1 can be made of elastic material and, during installation, can be compressed at both ends to engage with the front links 2 and rear links 3. The limiting structures 4 can be integrated with the support beams 1 or mounted on the outer side of each support beam 1 via fixings.
[0040] In this embodiment, two support beams 1 are provided as the main support for the material box 8 to bear the pressure caused by the weight of the material box 8 itself, providing a stable support base for the material box 8. By providing a front connecting rod 2 and a rear connecting rod 3 at the front and rear ends of the two support beams 1, respectively, the pressure on the support beam 1 can be effectively transferred to the connecting rod, which can further enhance the overall load-bearing capacity and enable the cargo grid unit 9 to accommodate heavier material boxes 8. By fastening the support beam 1 to the front connecting rod 2 and the rear connecting rod 3, a single unit is formed, which can better resist external loads and external stresses and improve the overall rigidity of the cargo grid unit 9. In addition, the fastening connection method is relatively simple and does not require the use of complex installation tools, which helps to reduce installation costs and time and improve installation efficiency. By making the top surface height of the support beam 1 lower than the top surface height of the rear connecting rod 3, the rear of the material box 8 can be limited, effectively preventing the material box 8 from shifting to the rear, which may cause the material box 8 to fall or cause a malfunction in the retrieval of the goods. By placing the limiting structure 4 on the outer side of each support beam 1 along the length direction of each support beam 1 (also the direction in which the material box 8 enters and exits), and with the limiting structure 4 being higher than the support beam 1, the material box 8 can be limited on both sides to prevent the material box 8 from shifting to the sides and causing problems in picking up goods. This structure can correct the posture of the material box 8 to a certain extent and can also effectively solve the problem of the material box 8 shifting on the vertical warehouse shelf.
[0041] Furthermore, in one embodiment, referring to Figure 3 , Figure 3 for Figure 1 Schematic diagram of the middle support beam 1. Figure 3 As shown, each end of the support beam 1 is provided with a snap hole 11, and the front link 2 and the rear link 3 are each provided with a toothed hook 21 that engages with the snap hole 11. In this embodiment, by providing snap holes 11 at each end of the support beam 1, and providing the front link 2 and the rear link 3 with toothed hooks 21 that engage with the snap holes 11, a strong connection force is provided, ensuring a secure connection between the front link 2 and the rear link 3 and the support beam 1. In addition, the design of the toothed hook 21 can increase the contact surface and friction at the connection point, thereby improving shear resistance and making the cargo grid unit 9 more stable and safe when bearing the weight of the material box 8.
[0042] In another embodiment, a toothed hook 21 may be provided at each end of the support beam 1 , and buckle holes 11 that engage with the toothed hook 21 may be provided on both the front connecting rod 2 and the rear connecting rod 3 .
[0043] Furthermore, in one embodiment, if Figure 3 As shown, the diameter of the snap holes 11 at the front end of the support beam 1 is larger than that at the rear end, and the snap holes 11 at the rear end tightly engage with the toothed hook 21. In this embodiment, a shuttle is required to remove and place the container 8. In this embodiment, the shuttle track 5 is mounted on the front link 2 of the cargo compartment 9. When the shuttle travels on the shuttle track 5, it inevitably causes vibrations in the cargo compartment 9, which can cause the container 8 to shift. By making the snap holes 11 at the front end of the support beam 1 larger than those at the rear end, and by tightly engaging the snap holes 11 at the rear end with the toothed hook 21, the front end of the support beam 1 and the front link 2 are loosely coupled, while the rear end of the support beam 1 and the rear link 3 are tightly coupled. This significantly reduces vibrations on the track when they are transmitted to the support beam 1 through the front link 2, thereby ensuring that the container 8 does not easily shift.
[0044] Furthermore, in one embodiment, if Figure 3 As shown, the cross-section of the support beam 1 is groove-shaped, with its opening facing downward. There are at least two snap-fit holes 11 at each end of the support beam 1, located on either side of the groove. In this embodiment, the cross-section of the support beam 1 is groove-shaped, with its opening facing downward. This allows the top surface of the support beam 1 to be flat, making it easier to remove and place the material box 8 and ensuring its stability.
[0045] As can be seen from the above embodiment, each end of the support beam 1 is provided with a snap hole 11, but the number and installation position of the snap holes 11 are not required, as long as they can ensure the snap connection between the support beam 1 and the front connecting rod 2 and the rear connecting rod 3. However, in this embodiment, the cross-section of the support beam 1 is groove-shaped, with its opening facing downward. Due to its special structural features, the number of snap holes 11 at each end of the support beam 1 is at least two, and they can be respectively located on the two side walls of the groove-shaped support beam 1. This ensures that the top surface of the support beam 1 is always on the same horizontal plane, which helps prevent the material box 8 from tilting when placed.
[0046] Furthermore, in one embodiment, referring to Figure 4 and Figure 5 , Figure 4 for Figure 1 Schematic diagram of the connection between the middle support beam 1 and the front link 2, Figure 5 for Figure 1 Schematic diagram of the connection between the middle support beam 1 and the rear link 3. Figure 4 and Figure 5As shown, both the front link 2 and the rear link 3 are provided with mounting grooves for accommodating the end face of the support beam 1, and toothed hooks 21 are disposed on the inner side faces of the mounting grooves. In this embodiment, by providing mounting grooves for accommodating the end face of the support beam 1 on both the front link 2 and the rear link 3, and disposing the toothed hooks 21 on the inner side faces of the mounting grooves, the front link 2 and the rear link 3 are tightly fitted with the end face of the support beam 1, reducing the possibility of relative movement, thereby improving the stability of the connection. At the same time, the toothed hooks 21 on the inner side faces of the mounting grooves can further increase the friction at the connection point, preventing the support beam 1 from sliding or falling off when subjected to force, thereby enhancing the firmness of the connection.
[0047] Furthermore, in one embodiment, if Figure 4 and Figure 5 As shown, the mounting groove of the front link 2 is a narrow mounting groove 22, and the mounting groove of the rear link 3 is a wide mounting groove 31. Each support beam 1 corresponds to two narrow mounting grooves 22 and one wide mounting groove 31. The toothed hooks 21 on the inner sides of the two narrow mounting grooves 22 are symmetrical about the middle position of the two narrow mounting grooves 22, and both inner sides of the wide mounting groove 31 are provided with toothed hooks 21. In this embodiment, by configuring the mounting groove of the front link 2 as a narrow mounting groove 22 and the mounting groove of the rear link 3 as a wide mounting groove 31, each support beam 1 corresponds to two narrow mounting grooves 22 and one wide mounting groove 31. This can reduce installation strength and facilitate disassembly. The toothed hooks 21 on the inner sides of the two narrow mounting grooves 22 are symmetrical about the middle position of the two narrow mounting grooves 22, and both inner sides of the wide mounting groove 31 are provided with toothed hooks 21. This can avoid stress concentration, enhance the strength of the connection, and prevent deformation easily when subjected to external forces.
[0048] Furthermore, in one embodiment, if Figure 3 As shown, the limiting structure 4 is formed by further extending the outer side surface of the support beam 1 and bending it 180 degrees in the opposite direction, that is, the limiting structure 4 is the side wall fold of the support beam 1. In this embodiment, the limiting structure 4 is formed by further extending the outer side surface of the support beam 1 and bending it 180 degrees in the opposite direction, that is, the limiting structure 4 is the side wall fold of the support beam 1. The limiting structure 4 and the support beam 1 are designed as one body, which can avoid the loose connection caused by traditional connection methods, significantly improve the overall strength, and ensure that it has higher stability and safety when bearing external loads; at the same time, the limiting structure 4 can more effectively disperse the stress borne by the support beam 1, avoiding stress concentration.
[0049] Furthermore, in one embodiment, if Figure 3 As shown, the end of the limiting structure 4 facing the front link 2 is tilted outward to form a guide surface 41. In this embodiment, by tilting the end of the limiting structure 4 facing the front link 2 to form the guide surface 41, the material box 8 can be smoothly placed on the support beam 1 along the guide surface 41, reducing the risk of inaccurate initial placement of the material box 8.
[0050] Furthermore, in one embodiment, referring to Figure 6 , Figure 6 Schematic diagram of the shelf of the shuttle car storage system in the embodiment of the present application. Figure 6 As shown, the shelves of the shuttle car vertical warehouse system include a multi-layer shuttle car track 5, each layer of the shuttle car track 5 is connected by a support rod 6, and a row of shelf units 7 are respectively provided on both sides of each layer of the shuttle car track 5. Each shelf unit 7 includes a plurality of cargo grid units 9 arranged in parallel as described in any of the above embodiments, and the front connecting rod 2 of each cargo grid unit 9 faces the shuttle car track 5. The rows of shelf units 7 located on the same side of the shuttle car track 5 are connected by support rods 6. In this embodiment, the shelves are indispensable in the entire shuttle car vertical warehouse system. The shelves include a multi-layer shuttle car track 5, each layer of the shuttle car track 5 is connected by support rods 6, so that the shuttle car can move smoothly on the shuttle track. By providing a row of shelf units 7 on both sides of each layer of the shuttle car track 5, it is equivalent to one shuttle car being responsible for picking up and placing the material boxes 8 of two rows of shelf units 7, which not only saves storage space but also helps to save costs.
[0051] Each shelf unit 7 includes a plurality of cargo grid units 9 as described in any of the above embodiments, arranged in parallel, and the front connecting rod 2 of each cargo grid unit 9 faces the shuttle track 5. The rows of shelf units 7 on the same side of the shuttle track 5 are connected by support rods 6. Through the above arrangement, it can be ensured that multiple material boxes 8 can be placed on each shelf unit 7, and a certain distance can be maintained between different material boxes 8. When the shuttle vehicle takes in and puts in the material boxes 8, it is avoided that the material boxes 8 are difficult to take out and put in. At the same time, it is also beneficial for the shuttle vehicle vertical warehouse system to accurately record the position of the material boxes 8, which is convenient for future retrieval. At the same time, the front connecting rod 2 of each cargo grid unit 9 is arranged toward the shuttle track 5. This ensures that the material boxes 8 are easier to place in the cargo grid unit 9, reducing the risk of inaccurate initial placement of the material boxes 8.
[0052] Furthermore, in one embodiment, referring to Figure 7 , Figure 7 for Figure 6 Schematic diagram of two rows of shelf units 7 on the same level. Figure 7 As shown, each layer has two shuttle rails 5, which are respectively installed on the front connecting rods 2 of the cargo grid units 9 arranged on both sides thereof. In this embodiment, each layer has two shuttle rails 5. By installing the two shuttle rails 5 on the front connecting rods 2 of the cargo grid units 9 arranged on both sides thereof, the shelf space can be more effectively utilized, the structure is made more compact, and at the same time, the material boxes 8 can be quickly taken in and out.
[0053] In addition, in another embodiment, the shelf may further include a lifting mechanism for connecting the shuttle tracks 5 on each layer. In this way, there is no need to place a shuttle on each layer, which can effectively reduce the number of shuttles and control management costs.
