Description

Cache plate, cache rack, shelf and storage system

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on March 1, 2024, with application number 202420405657.5 and invention name “A cache plate, cache rack, shelf and storage system”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of warehousing systems, and in particular to a cache plate, a cache rack, a shelf and a warehousing system. Background Art

[0003] At present, automatic handling equipment is often used in intelligent warehousing systems to transport material boxes to the target location. Generally, the target locations of material boxes are workstations in the warehousing system (where material boxes are centrally sorted and processed), cache locations on shelves, and storage locations on shelves. Among them, the material box handling work between workstations and cache locations is generally completed using latent handling equipment, which has the advantages of fast speed and high efficiency. The material box handling work between cache locations and storage locations is generally completed using fork-type handling equipment, which is easy to cooperate with the lifting mechanism. It can push and pull the forked material box from the outside of the shelf relative to the cache location or storage location, and then drive the material box to the target cache location or target storage location through translation or lifting movements.

[0004] In order to make full use of the storage space, the relevant technology designs the length, width and height of the storage location to be closer and closer to the material box, so that more material boxes can be stored in the same storage space. Then this requires the handling equipment to have a very high position control accuracy when taking and placing the material box relative to the storage location (cache location or storage location), otherwise it may not be possible to accurately place the material box on the corresponding storage location. This will undoubtedly increase the manufacturing cost of the handling equipment. In addition, in the current storage system, the aforementioned two different handling equipment tend to walk in the same aisle, which makes it very difficult to plan and design the passage procedure of the handling equipment, or it is necessary to reduce the number of shelves arranged and reserve sufficient aisle width for the handling equipment to pass, thus reducing the utilization rate of the storage space. Summary of the Invention

DETAILED DESCRIPTION

[0043] To make the objectives, technical solutions, and advantages of this application more clearly understood, the present application is further described below with reference to the accompanying drawings and examples. It is apparent that the described examples are only a portion of the embodiments of this application, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the examples in this application are intended to fall within the scope of protection of this application.

[0044] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described in the embodiments are intended to be used to explain the present application and should not be construed as limiting the present application.

[0045] References in this specification to "one embodiment," "an example," or "an example" mean that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment disclosed herein. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

[0046] The present embodiment provides a buffer plate, as shown in FIG1 , which is a schematic structural diagram of a buffer plate 1 provided in an embodiment of the present application. The buffer plate 1 includes a plate body 10, on which are formed a first guide structure 11 extending along its width direction and a second guide structure 12 extending along its length direction. The first guide structure 11 is located at one end of the plate body 10 along the length direction of the plate body 10. The first guide structure 11 is formed with a first guide slope 110, and the second guide structure 12 is formed with a second guide slope 120. In addition, a support surface 100 is formed on the plate body 10, and the support surface 100 is located on one side of the second guide structure 12. The first guide slope 110 and the second guide slope 120 both form an obtuse angle with the support surface 100. This arrangement enables the first guide slope 110 and the second guide slope 120 to guide the material box when the material box is placed on the support surface 100 along a first set direction.

[0047] For ease of description, as shown in Figure 1, in this embodiment, the direction perpendicular to the support surface 100 is defined as the first set direction X, the length direction of the board body 10 is defined as the second set direction Y, and the width direction of the board body 10 is defined as the third set direction Z.

[0048] The buffer plate 1 provided in this embodiment can be applied to a shelf. A buffering position can be formed using the support surfaces 100 of two adjacent buffer plates 1 spaced apart. When a container is placed into the buffering position along a first predetermined direction X, the first guide slope 110 and the second guide slope 120 provided on the buffer plate 1 can be used to guide the container accurately into position, thereby reducing the control accuracy requirements for the handling equipment. In a warehouse system, a first handling device is used to transport containers back and forth between a workstation and a buffering position, and a second handling device is used to transport containers between the buffering position and a storage position on the shelf. The first handling device is typically a latent lifting robot. To place a container into the buffering position, the first handling device first carries the container to the target buffering position, then uses its own lifting mechanism to lift the container to a predetermined height above the support surface 100. The robot then moves slowly along a second predetermined direction Y beneath the buffer plate 1 (at this point, the container carried by the first handling device is above the buffer plate 1 and above the support surface 100). The lifting mechanism then controls the container's descent and placement onto the support surfaces 100 of two adjacent buffer plates 1. Since the first guide slope 110 and the second guide slope 120 can serve as a limit guide for the material box during its descent, the control accuracy requirement for the first transporting device can be reduced, thereby reducing the design and manufacturing cost of the first transporting device.

[0049] The cache plate 1 shown in FIG1 includes only one second guide structure 12, that is, in the cache plate 1, one second guide structure 12 is formed along the length direction of the plate body 10 and is arranged on one side of the plate body 10. Specifically, along the second set direction Y, the second guide structure 12 is formed on the left side of the plate body 10, that is, the second guide structure 12 is located on the left side of the support surface 100. FIG2 shows a cache plate 1 of another structural form. FIG2 is a schematic structural diagram of another cache plate 1 provided in an embodiment of the present application. In the cache plate 1 shown in FIG2, only one second guide structure 12 is also provided, and the second guide structure 12 is also arranged on one side of the plate body 10. However, the second guide structure 12 in FIG2 is formed on the right side of the plate body 10 along the second set direction Y, that is, the second guide structure 12 is located on the right side of the support surface 100. Furthermore, FIG3 shows another structural form of a cache plate 1. FIG3 is a schematic structural diagram of another cache plate 1 provided in an embodiment of the present application. In the cache plate 1 shown in FIG3 , two second guide structures 12 are formed, and the two second guide structures 12 are formed in the middle of the plate body 10 symmetrically with respect to the length direction of the plate body 10. That is, there are two second guide structures 12 in FIG3 and they are formed on the left and right sides of the plate body 10 along the second set direction Y, respectively. That is, the two second guide structures 12 in FIG3 are symmetrically arranged along the second set direction Y, and the second guide slopes 120 of the two second guide structures 12 are spaced apart from each other on the sides close to the plate body 10, and are spaced apart from each other on the sides away from the plate body 10. The three different structures of the cache plates 1 can function better when arranged at different locations on the shelf. Of course, only one or two of the structures of the cache plates 1 can be arranged on the shelf, which will be explained in detail in the subsequent description of the shelf.

[0050] It should also be noted that since the cache plate 1 shown in Figure 3 has two second guide structures 12, two support surfaces 100 are formed on the plate body 10 accordingly, one of the support surfaces 100 is located on one side of one of the second guide structures 12, and the other support surface 100 is located on the side of the other second guide structure 12. The two support surfaces 100 are separated from each other by the two second guide structures 12, and the second guide slope 120 on the second guide structure 12 is at an obtuse angle to the support surface 100 on the same side thereof.

[0051] The second guide structure 12 shown in Figures 1 to 3 is a plate-like structure, and its side away from the support surface 100 is a hollow structure; in other embodiments of the present application, the second guide structure 12 may also be a block-like structure, and its side away from the support surface 100 is a solid structure.

[0052] Furthermore, as shown in FIG1 , FIG2 , or FIG3 , the first guide structure 11 in the cache plate 1 provided in this embodiment further comprises a first limiting surface 111 perpendicular to the support surface 100. The first limiting surface 111 extends along the width direction of the plate body 10 and is located between the first guiding inclined surface 110 and the support surface 100. The first limiting surface 111 can limit the outer wall of the material box placed on the support surface 100, preventing the material box from excessively moving along the second set direction Y. Similarly, the second guide structure 12 in the cache plate 1 further comprises a second limiting surface 121 perpendicular to the support surface 100. The second limiting surface 121 extends along the length direction of the plate body 10 and is located between the second guiding inclined surface 120 and the support surface 100. The second limiting surface 121 can limit the outer walls of the material box placed on the support surface 100, preventing the material box from shaking to the left and right sides along the second set direction Y.

[0053] Furthermore, a third guide slope 122 and a fourth guide slope 130 are formed on the end of the buffer plate 1 away from the first guide structure 11. The third guide slope 122 and the fourth guide slope 130 are both used to guide the material box when it is placed on the support surface 100 along the second set direction Y. Specifically, a third guide slope 122 is further formed on the end of the second guide structure 12 away from the first guide structure 11. The third guide slope 122 is perpendicular to the support surface 100 and forms an obtuse angle with the first limiting surface 111, so that the third guide slope 122 can guide the material box when it is placed on the support surface 100 along the second set direction Y. A bent section 13 is further formed on the plate body 10 at one end away from the first guide structure 11. The bent section 13 has a fourth guide slope 130 formed thereon. The fourth guide slope 130 is bent relative to the support surface 100 in the first set direction X. The fourth guide slope 130 forms an obtuse angle with the first limiting surface 111, so that the third guide slope 122 can guide the material box when it is placed on the support surface 100 in the second set direction Y. The first guide structure 11 and the bent section 13 can be formed by bending the plate body 10 at both ends in the second set direction Y.

[0054] As mentioned above, a second handling device is generally used in a warehousing system to carry boxes between the buffer and storage locations on the shelves. The second handling device is generally a fork-type handling robot. When placing a box at the buffer, it first carries the box to the target buffer so that the box and the support surface 100 are at the same height. Then, it uses its own telescopic fork mechanism to push the box along the second set direction Y. Since the third guide slope 122 and the fourth guide slope 130 play a limiting and guiding role for the box during the pushing process, the control accuracy requirement for the above-mentioned second handling device can be reduced (before pushing the box, there is no need to keep the bottom surface of the box and the support surface 100 at a high precision level), thereby reducing the design and manufacturing cost of the second handling device.

[0055] As shown in Figure 4, Figure 4 is a structural schematic diagram of the cache plate 1 in Figure 3 from another perspective. In this embodiment, the surface of the plate body 10 on the side facing away from the support surface 100 is also formed with reinforcing ribs 14. By providing the reinforcing ribs 14, the overall structural strength of the cache plate 1 can be improved, so that it can carry heavier material boxes.

[0056] As shown in Figures 5a and 5b, Figure 5a is a schematic structural diagram of a cache rack equipped with the cache plate 1 provided in this embodiment, and Figure 5b is a side view of Figure 5a. The cache plate 1 provided in this embodiment can be applied to a cache rack, which includes a connecting frame, a cantilever 4, and the cache plate 1 provided in this embodiment. In this embodiment, the cache rack is equipped with three different cache plates 1 of the structures shown in Figures 1, 2, and 3. Specifically, the cache plate 1 in this embodiment is fixedly mounted to the connecting frame via the cantilever 4. The connecting frame is also provided with a docking member 20 for mounting with a shelf. The cache plate 1 and the cantilever 4 can be fixed together using fasteners or welding; the cantilever 4 and the connecting frame can be fixed together using fasteners or welding; and the connecting frame and the docking member 20 can be fixed together using fasteners or welding. The cache plates 1 are arranged in a layer, and along the third set direction Z in Figure 5a, the cache plates 1 arranged in this layer sequentially include one cache plate 1 shown in Figure 1, three cache plates 1 shown in Figure 3, and one cache plate 1 shown in Figure 2. The support surfaces 100 on the two adjacent cache plates 1 on the same layer cooperate to form a cache position for storing material boxes, and the first guide slope 110 and the second guide slope 120 on the two adjacent cache plates 1 on the same layer cooperate to form an opening that gradually narrows along the first set direction X.

[0057] As previously described, by cooperating with the first guide slope 110 and the second guide slope 120 on the two adjacent cache plates 1 on the same layer, the first guide slope 110 and the second guide slope 120 can limit the position of the material box when the first handling device is used to place the material box on the support surface 100 along the first set direction X. This eliminates the need for the first handling device to accurately control the material box in advance so that the material box is directly above the cache position, and allows a certain range of error in the left, right, and rear sides of the material box relative to the cache position. This can reduce the control accuracy requirements of the first handling device, thereby reducing the design and manufacturing costs of the first handling device.

[0058] The cache rack in this embodiment is equipped with three different structural forms of cache plates 1 shown in Figures 1, 2, and 3. In other optional embodiments, only the cache plate 1 shown in Figure 3 (i.e., a cache plate 1 with two second guide structures 12 provided on the plate body 10) may be used; or, one of the cache plates 1 shown in Figure 1 and the cache plate 1 shown in Figure 2 may be selected for use in conjunction with the cache plate 1 shown in Figure 3; or, the cache plate 1 shown in Figure 1 may be selected for use in conjunction with the cache plate 1 shown in Figure 2. It is sufficient that the two opposing second guide slopes 120 on two cache plates 1 arranged adjacent to each other on the same layer intersect.

[0059] In addition, the cache plates 1 in this embodiment are arranged in a single layer, and the number is as described above. In other optional embodiments, the cache plates 1 may be arranged in multiple layers as needed, with the number of cache plates 1 sufficient to ensure that at least two cache plates 1 are spaced apart in the same layer. The number of cache plates 1 arranged and the number of layers are generally determined by the number of storage locations on the shelf, generally maintaining a reasonable ratio of cache locations to storage locations.

[0060] The connecting frame in this embodiment includes two parallel and spaced connecting beams 2 and a plurality of connecting rods 3. The two connecting beams 2 are fixedly connected by the connecting rods 3, and the plurality of connecting rods 3 are evenly distributed along the length of the connecting beams 2. Optionally, the connecting beams 2 may be provided with a plurality of tubular connectors extending along the second set direction Y. The plurality of tubular connectors are sequentially spaced along the extension direction of the connecting beams 2. The ends of the connecting rods 3 may be inserted into the tubular connectors, and the tubular connectors and the connecting rods 3 are fixed by fasteners to secure the connecting beams 2 and the connecting rods 3.

[0061] The cache rack shown in FIG5a can be applied to a shelf. Specifically, as shown in FIG6, FIG6 is a schematic structural diagram of a shelf equipped with the cache rack shown in FIG5a. The shelf includes a frame body with storage locations formed thereon. The shelf also includes a cache rack equipped with the cache plate 1 provided in this embodiment. The cache rack is fixed to the frame body via a docking member 20, and the horizontal height of the cache locations formed between adjacent cache plates 1 is lower than the horizontal height of the storage locations. At the same time, along the length direction of the cache plates 1, the shelf forms a first longitudinal passage between two adjacent cache plates 1 on the same level for the passage of a first handling device carrying a material box; the shelf forms a first transverse passage below the cache plate 1 along the width direction of the cache plate 1 for the passage of the first handling device carrying a material box; and the shelf forms a second transverse passage below the lowest level of the shelf body along the width direction of the cache plate 1 for the passage of the first handling device carrying a material box.

[0062] The frame in this embodiment includes two sets of spaced support columns, multiple layers of support beams 6 fixedly connected between the two sets of support columns, and multiple span beams 7 fixedly mounted on each layer of support beams 6. Two adjacent span beams 7 on each layer of support beams 6 cooperate to form a storage location. As shown in Figure 6, it is easy to understand that in this embodiment, the second set direction Y is in the same direction as the length of the cache plate 1 and the width of the support beams 6, and the third set direction Z is in the same direction as the width of the cache plate 1 and the length of the support beams 6.

[0063] By designing the size ratio of the frame body and the cache rack, the size of the cache rack is no more than half the size of the frame body along the second set direction Y, so that the aforementioned first transverse channel and second transverse channel can be formed below the entire shelf.

[0064] As shown in FIG7 , which is an enlarged schematic diagram of part A in FIG6 , a horizontal brace 50 and a diagonal brace 51 are provided between two adjacent columns 5 in the same group. The columns 5 are reinforced by the horizontal brace 50 and the diagonal brace 51. At the same time, the docking member 20 on the cache rack can be hung on the horizontal brace 50 located on the bottom layer of the shelf. The docking member 20 can be hung on the horizontal brace 50 located on the outermost side in the third set direction Z. Of course, in other optional embodiments, the docking member 20 can also be designed to be hung on the support beam 6 or the span beam 7. Alternatively, connection methods other than hanging, such as welding, clamping, or bolting, can also be used.

[0065] Furthermore, in order to improve the storage density of the shelf, the present embodiment also designs the specific structure of the shelf, as shown in Figure 9, which is a structural schematic diagram of the support beams 6 and cross beams 7 located on the same layer in the shelf. Each group of support columns in the shelf includes three columns 5 arranged at intervals along the length direction of the support columns, and the columns 5 in the two groups of support columns are arranged at intervals along the width direction of the support columns; each layer of support beams 6 includes a first cross beam 60 and two second cross beams 61, the first cross beam 60 is fixedly arranged between the two corresponding columns 5 located in the middle, and the two second cross beams 61 are respectively fixedly arranged between the two corresponding columns 5 located at both ends; a cross beam 7 is fixedly arranged between the first cross beam 60 and any second cross beam 61 arranged on the same layer.

[0066] Through the above design, as shown in FIG12 , in one layer of storage locations on the shelf, a column of storage locations arranged along the second set direction Y has four storage locations, which can significantly increase the number of storage locations on a single shelf and improve the storage density.

[0067] In addition, a cache rack is arranged on each of the left and right sides of the shelf along the length direction of the support beam 6 in this embodiment. Along the second set direction Y, a first transverse channel, two second transverse channels, and another first transverse channel are formed in sequence below the shelf. As shown in Figures 8 and 14, Figure 8 is a top view of the shelf in Figure 6, and Figure 14 is a side view of the shelf in Figure 12. The shelf provided in this embodiment can form four first longitudinal channels between two adjacent cache plates 1 below the shelf along the second set direction Y, and can also form two first transverse channels and two second crossbeam 61 channels below the shelf along the third set direction Z. The first longitudinal channel allows the first handling equipment to pass through with a material box (correspondingly, the first handling equipment must also be allowed to pass empty); the first transverse channel allows the first handling equipment to pass empty, and the second transverse channel allows the first handling equipment to pass through with a material box (correspondingly, the first handling equipment must also be allowed to pass empty). As a result, the passage routes of the first transport equipment are significantly increased, the overlap of the passage routes of the first transport equipment and the second transport equipment is reduced, and it is more convenient to plan the passage procedures of the first transport equipment and the second transport equipment. At the same time, the spacing between adjacent shelves can be reduced, thereby improving the utilization rate of storage space.

[0068] With reference to Figures 10, 11, 12, and 13, Figure 10 is a schematic structural diagram of the support beam 6 and span beam 7 in Figure 9 from another perspective, Figure 11 is a side view of the support beam 6 and span beam 7 in Figure 9, Figure 12 is a schematic diagram of the shelf in Figure 6 storing material boxes 8, and Figure 13 is an enlarged schematic diagram of portion B in Figure 12. In this embodiment, the lower surface of the first crossbeam 60 on the same layer of support beam 6 is lower than the lower surface of the second crossbeam 61, thereby forming a stopper 600 on the first crossbeam 60. The stopper 600 is used to limit the movement of the material box 8 along the length direction of the buffer plate 1. That is, when the second handling device is used to place the material box 8 on the storage position, during the process of pushing the material box 8 along the second set direction Y to the storage position, the stopper 600 can limit the material box 8 and prevent the material box 8 from excessive movement along the second set direction Y. That is, the role played by the limiting portion 600 is the same as that played by the aforementioned first limiting surface 111 .

[0069] In this embodiment, the span beam 7 is clipped to the support beam 6. Specifically, a clip slot (not shown in the figure) is provided on each of the first cross beam 60 and the second cross beam 61. A clip plate (not shown in the figure) is provided at each end of the span beam 7. The span beam 7 is clipped to the clip slot on the support beam 6 on the corresponding side via the clip plate at its end. In addition, the structure of the span beam 7 is also designed in this embodiment. A reinforcing rib 70 is formed on the span beam 7. On the one hand, the reinforcing rib 70 is used to improve the structural strength of the span beam 7, so that it can accommodate heavier material boxes. On the other hand, the reinforcing rib 70 can be used to limit the position of the material box placed in the storage position. It is easy to understand that the limiting effect of the reinforcing rib 70 on the material box in the storage position is the same as the limiting effect of the second limiting surface 121 on the material box in the cache position.

[0070] The above-mentioned shelves can be applied to a warehousing system, which includes a first handling device, a second handling device and the shelves mentioned above in this embodiment, wherein the first handling device is used to transport material boxes between the workstation and the cache position of the shelf, and the second handling device is used to transport material boxes between the cache position and the storage position on the shelf, and an aisle is formed between adjacent shelves for the second handling device to pass through.

Those skilled in the art should understand that the present application includes but is not limited to the contents described in the drawings and the above specific embodiments.
