Description

Technical Field

[0001] The present application relates to the field of warehousing technology, and in particular to a shelf and a warehousing system. Background Art

[0002] With the rapid development of the logistics industry, the warehousing system is also constantly innovating, and the current warehousing system is becoming more and more intelligent and automated. In the automated warehousing system where robots are responsible for handling boxes, large handling robots or automatic guided vehicles (AGVs) are required to handle boxes at different heights on the shelves, which takes up a lot of space, reduces the storage capacity, and increases the cost of handling boxes.

[0003] In the related technology, there is also a popular operation mode of "cooperative transportation of large and small vehicles", that is, the large AGV with a lifting mechanism is responsible for the transportation between the cache and storage locations, while the small robot is responsible for the transportation between the cache and the workstation. In this mode, if the large AGV has a chassis, it will reduce the movement route of the small robot, thereby reducing the transportation efficiency of the system.

[0004] The shelf in the related art generally includes at least one temporary storage layer, at least one storage layer board, and multiple columns arranged at intervals in the horizontal direction; the temporary storage layer is used to provide multiple temporary storage positions, and the storage layer board is used to provide multiple storage positions. However, the temporary storage layer in the related art cannot enable the material box handling robot to carry the material box across the shelf, which limits the movement space of the handling robot, makes it inconvenient to plan the moving route of the handling robot, and affects the work efficiency.

[0005] In addition, in order to ensure maximum utilization of the shelves in the current warehousing system, the number of storage layers on the high-rise shelves is set to increase. The increase in the number of storage layers can improve the storage capacity rate, but when the high-rise shelves have too many storage layers and the number of temporary storage locations does not increase, the gap between the number of storage locations and temporary storage locations will increase, affecting the handling efficiency of the material box in and out of the warehouse. Utility Model Content

[0006] The present application aims to solve one of the technical problems in the related art to a certain extent. To this end, the present application provides a shelf and storage system.

[0007] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a shelf, comprising a plurality of columns, at least one storage layer fixed to the columns, at least two support members are provided on the bottom side of the storage layer of the bottom layer, the height direction of the support members is consistent with the height direction of the columns, a gap is formed between two adjacent support members, and at least two temporary storage layers are provided between two adjacent support members, at least two temporary storage layers are arranged along the height direction of the columns, each temporary storage layer comprises two temporary storage pallets respectively arranged on corresponding two adjacent support members, the gap between the two temporary storage pallets of the same temporary storage layer forms a first channel, and multiple first channels between two adjacent support members pass through in the height direction of the columns.

[0008] In the present technical solution, by arranging at least two temporary storage layers at the bottom of the shelf, the number of temporary storage positions is increased by increasing the number of temporary storage layers within a limited range at the bottom of the shelf. When there are too many storage layers on the high-level shelf, the ratio of the number of storage positions to temporary storage positions is optimized, so that too few temporary storage positions will not become a bottleneck in the handling efficiency of the material box in and out of the warehouse. In addition, by arranging a first channel on each temporary storage layer, and the multiple first channels between adjacent support members are interconnected, the handling robot can conveniently carry or store materials in the high-level temporary storage positions, and in actual use, the handling robot can pass through the first channel to cross the shelf, so that its route has more options, thereby improving the handling efficiency.

[0009] Optionally, the shelf has a first direction and a second direction orthogonal to the first direction, and a plurality of supports are arranged along the first direction of the shelf, the supports include two side supports and an intermediate support located between the two side supports, a temporary storage pallet is provided on one side of the side support, and temporary storage pallets are provided on both sides of the intermediate support.

[0010] Optionally, the length of the support in the second direction is less than the length of the shelf in the second direction. In this way, a certain space is reserved at the bottom of the shelf on one side of the support, and the space can be used as an area for the robot to walk under the shelf when carrying goods, thereby improving the carrying efficiency.

[0011] Optionally, one end of the support member is flush with one side of the shelf in the second direction, or the support member is installed in the middle position of the shelf in the second direction.

[0012] Optionally, the support member is fixed to a column or a storage layer of the bottom layer.

[0013] Optionally, the temporary storage tray of the bottom layer is arranged at the bottom of the support member and there is a height difference between the bottom wall thereof and the bottom surface of the column, so that space is reserved below the temporary storage tray.

[0014] Optionally, each of the temporary storage pallets is provided with a guide device for guiding the goods to be placed on the temporary storage pallet.

[0015] The guide device comprises a first guide member, a second guide member and a third guide member;

[0016] One end of the temporary storage pallet is tilted downward to form the first guide, the other end of the temporary storage pallet is provided with a second guide, the upper end of the second guide is provided with a second guide slope facing the first guide, the upper end of the temporary storage pallet is provided with a third guide arranged along the length of the temporary storage pallet, the upper end of the third guide is provided with a third guide slope facing the first channel, and the end of the third guide close to the first guide is provided with a fourth guide slope. The guide device can guide the robot to place the transported materials on the temporary storage layer from multiple dimensions, ensure the smoothness and standardization of material placement, and improve the material handling efficiency.

[0017] In addition, the present application also provides a storage system, including a first handling robot and a second handling robot, and at least two rows of shelves as in any one of the above technical solutions, wherein the first handling robot is used to carry and place material boxes between two storage layers or between a temporary storage layer and a storage layer;

[0018] The second handling robot is used for carrying / taking and placing material boxes on the temporary storage layer, and the lifting mechanism of the second handling robot can pass through the first channel.

[0019] The first channel in this technical solution has a certain spacing, and the width of the lifting mechanism of the second handling robot is smaller than the width of the spacing, so that during the handling process, the second handling robot can pass through the first channel and then cross the shelf when in the lifting state, which can avoid detours, optimize the passage path, and improve the handling efficiency. In addition, the first channels on the multi-layer temporary storage layer are interconnected, so that the lifting mechanism of the second handling robot can pass through multiple first channels in the vertical direction to realize the handling or placement of materials on the high-level temporary storage layer, which well matches the handling requirements of the multi-layer temporary storage layer.

[0020] Optionally, a second passage is formed below each row of shelves on one side of the support member, and the second passage is used for the first handling robot or the second handling robot to pass along the length direction of the shelf. The second passage is set below the shelf, so that the robot can move below the shelf when moving, reducing the walking route in the public area outside the shelf, avoiding route interference between multiple robots or between the robot and other equipment, improving the orderliness of the entire storage system, and improving the handling efficiency.

[0021] Optionally, a space is formed under the temporary storage pallet on the bottom layer of the shelf to allow the passage of an unloaded second handling robot. The space is formed by the height difference between the temporary storage pallet and the bottom surface of the column. The space is relatively low, allowing the passage of an unloaded second handling robot, providing more possible routes for the unloaded state of the second handling robot during the reciprocating handling process, facilitating route planning and improving handling efficiency.

[0038] The embodiments of the present application are described in detail below, and 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 with the same or similar functions. The embodiments based on the embodiments are intended to be used to explain the present application and cannot be understood as limiting the present application.

[0039] References to "one embodiment" or "an example" or "an example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed in the present application. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0040] In smart warehousing, there are generally multiple tall shelves. In order to make better use of space, the height of a shelf can reach several meters or even dozens of meters. There are multiple layers of storage shelves on the shelves to store goods. In daily work, when it is necessary to access goods in high positions, in order to ensure the rapid sorting of goods, it is generally necessary to move the high goods to the temporary storage layer at the bottom of the shelf first, so that small robots can quickly transport them.

[0041] In the following figures, arrow X is used to indicate the first direction (generally referring to the length direction of the shelf), arrow Y is used to indicate the second direction (generally referring to the width direction of the shelf), and arrow Z is used to indicate the height direction. The X direction, Y direction, and Z direction intersect and are orthogonal to each other.

[0042] See attached Figure 1 , Figure 7 One embodiment of the utility model discloses a shelf, including a plurality of columns 1, at least one storage layer 2 fixed to the columns 1, the storage layers 2 are spaced apart along the height direction of the columns 1, and the storage layers 2 can be made of plates or frame structures, and are used to store material boxes, cargo boxes, etc., and are generally multi-layered. The plurality of columns 1 are generally supported at the four corners of the storage layer 2. Of course, when necessary, for example, when the width and length of the shelf are long, in order to ensure the overall strength and stability of the shelf, additional columns 1 can be added in the middle of the length and width directions for support.

[0043] In this embodiment, at least two support members are provided on the bottom side of the bottom storage layer plate, wherein a space of a certain height is reserved between the bottom storage layer plate 2 and the ground, and at least two support members 3 are provided in the space, and the height direction of the support members 3 is consistent with the height direction of the column, and a gap is formed between two adjacent support members 3, and at least two temporary storage layers are provided between two adjacent support members 3, and at least two temporary storage layers are arranged along the height direction of the column, and materials that need to be temporarily stored can be placed on each temporary storage layer, and each temporary storage layer includes two temporary storage pallets 4 respectively arranged on the corresponding two adjacent support members 3, and the temporary storage pallet 4 is a structure with one end fixed on the support member 3 and the other end extending to the middle part of the two adjacent support members 3. When the material is placed on the temporary storage pallet 4, the bottom surface of the material is supported by the two temporary storage pallets 4 at the same time and then stored in the temporary storage layer.

[0044] In this embodiment, by setting up at least two temporary storage layers on the bottom side of the shelf, the number of temporary storage positions is increased by increasing the number of temporary storage layers within the limited range at the bottom of the shelf. When there are too many storage layers at the high positions of the shelf, the number of temporary storage layers can be increased as needed, thereby optimizing the ratio of the number of storage positions to temporary storage positions, so that too few temporary storage positions will not become a bottleneck in the handling efficiency of the material box in and out of the warehouse.

[0045] In this embodiment, the interval between two temporary storage pallets 4 of the same temporary storage layer is formed as a first channel 5, and a plurality of first channels 5 between two adjacent support members 3 are connected in the height direction of the column 1. In this way, when used, the handling robot can conveniently carry or store materials on the high temporary storage layer, and the handling robot can cross the shelf through the first channel 5, reducing detours, making its route more selective, and improving handling efficiency.

[0046] In order to better understand the structure of the multi-layer temporary storage layer in this embodiment, an example is given below: Figure 1 , Figure 2 , Figure 3 , the temporary storage layer is set to two layers, the temporary storage pallet 4 close to the ground becomes the first temporary storage pallet, and the one far from the ground becomes the second temporary storage pallet. The space enclosed by the two supports 3, the first temporary storage pallet and the second temporary storage pallet forms the first temporary storage layer; the space enclosed by the two supports 3, the second temporary storage pallet and the storage layer 2 forms the second temporary storage layer. In actual settings, the width of the supports 3 and the temporary storage pallet 4 is set to be slightly larger than the width of the material, so that the material can be stored more stably on the temporary storage layer. In the height direction, the height space between the first temporary storage pallet (closest to the ground) and the second temporary storage pallet and the height space between the second temporary storage pallet and the lower plane of the bottom storage layer are greater than the height of the material box when it is separated from the temporary storage pallet 4. In this way, a certain space can be reserved to avoid interference of various components on the material when the robot lifts the material, making the material handling / pick-up and placement smoother.

[0047] The support member 3 in this embodiment plays the role of supporting the temporary storage pallet 4 and limiting the horizontal position of the material. When the support member 3 is actually set, it is suspended below the bottom storage layer 2. The support member 3 can be a straight rod or a Figure 3 The two straight rods (Y direction) shown are arranged side by side, and can also be a plate structure or a frame structure. In addition, the width between the two support members 3 is greater than the width of the material box and the sum of the movement error of the robot, so that the robot can avoid hitting the support member when carrying the material box.

[0048] See attached Figure 2 In one embodiment of the present application, the number of support members 3 is set to be multiple and arranged along the first direction (X direction, length direction) of the shelf. The support member 3 includes two side support members 31 and an intermediate support member 32 located between the two side support members 31. The side support members 31 are located at the edge position, and a temporary storage pallet 4 is provided on one side of the side support member 31, and temporary storage pallets 4 are respectively provided on both sides of the intermediate support member 32. In this way, the number of support members 3 can be reduced and more temporary storage positions can be provided.

[0049] See attached Figure 3 , the width of the support member 3 in the Y direction (second direction) in this embodiment is smaller than the width of the shelf in the Y direction (second direction). In this way, a certain space is reserved at the bottom of the shelf on one side of the support member 3, and the space can be used as an area for the robot to walk under the shelf when carrying goods, thereby improving the carrying efficiency. In actual settings, the width of the support member 3, the width of the shelf, and the size of the robot are comprehensively considered and determined to ensure that the robot can walk smoothly under the shelf.

[0050] Regarding the arrangement of the support member 3, the present application provides the following feasible implementation methods: first, see the attached Figure 3 , one end of the support 3 is flush with one side of the shelf in the second direction (Y direction, width direction), for example, one end of the support 3 is flush with the left end of the shelf in the second direction, and the other end of the support 3 extends to the middle position of the shelf in the second direction and there is a certain distance from the right end of the shelf. The height of the interval is the height from the ground to the bottom wall of the storage layer 2 at the bottom layer. The robot can pass along the first direction (X direction, length direction) of the shelf in the interval while carrying the material. Second, when the width of the shelf in the second direction is wider, the support 3 is installed in the middle position of the shelf in the second direction (not shown in the figure), so that there is a certain space between the two ends of the support 3 and the two ends of the shelf in the second direction, that is, the robot is allowed to pass along the length direction of the shelf while carrying the material at both ends of the support 3.

[0051] The support member 3 of one embodiment of the present invention is fixed on the column 1 or the storage layer 2 of the bottom layer, see the attached Figure 1 In actual setting, the side supports 31 on both sides can be directly fixed on the column 1, and the middle support 32 can be fixed on the bottom surface of the storage layer 2. Of course, the side supports 31 can also be directly fixed on the storage layer 2. In addition, a cache rack can be set below the storage layer 2, and the support 3 is fixed on the cache rack and fixed to the column 1 together with the cache rack, which can reduce the bearing capacity of the storage layer 2 and improve the overall strength of the shelf.

[0052] The temporary storage pallet 4 of the bottom layer of the utility model is arranged at the bottom of the support member 3 and there is a height difference between its bottom wall and the bottom surface of the column 1. In this way, a space is reserved below the temporary storage pallet 4; the space is formed by the height difference between the temporary storage pallet 4 and the bottom surface of the column 1. The space is relatively low, allowing the passage of an unloaded robot, and facilitating the unloaded robot to move to the bottom of the temporary storage layer to take the materials on the temporary storage layer.

[0053] See attached Figure 2 , Figure 4 In one embodiment of the utility model, each temporary storage pallet 4 is provided with a guide device for guiding the goods to be placed on the temporary storage pallet 4, and the guide device includes a first guide member 6, a second guide member 7 and a third guide member 8; one end of the temporary storage pallet is tilted downward to form the first guide member 6, and the second guide member 7 is provided on the upper part of the other end of the temporary storage pallet 4, and the upper end of the second guide member 7 is provided with a second guide slope 71 facing the first guide member 6, and the upper end of the temporary storage pallet 4 is provided with a third guide member 8 arranged along the length direction of the temporary storage pallet 4, and the upper end of the third guide member 8 is provided with a third guide slope 81 facing the first channel 5, and the end of the third guide member 8 close to the first guide member 6 is provided with a fourth guide slope 82.

[0054] In this embodiment, when the handling robot needs to place the material to be handled in the temporary storage layer, the robot carries the material and enters from one side of the first guide member 6. The material first passes through the first guide member 6. The downward inclined surface on the first guide member 6 will prevent the end of the temporary storage pallet 4 from blocking the entry of the material in the vertical direction. Secondly, the material will be guided by the fourth guide slope 82 on the third guide member 8 to adjust the position of the material in the width direction so that it is facing the temporary storage layer. The robot continues to move through the first channel 5. When it moves to the discharge position, the robot's lifting mechanism shrinks, and the material falls under the action of its own weight. Under the joint action of the second guide slope 71 of the second guide member 7 and the third guide slope 81 of the third guide member 8, the material falls smoothly into the temporary storage layer to achieve standardized storage of the material. It should be noted that the second guide member 7 also has the function of limiting the position of the material in the length direction of the temporary storage layer. It can be seen that the guide device can guide the robot to place the material to be handled on the temporary storage layer from multiple dimensions, ensure the smoothness and standardization of material placement, and improve the material handling efficiency.

[0055] When the above-mentioned shelves are applied to a warehousing system, the warehousing system includes the shelves, a first handling robot (not shown in the figure) and a second handling robot (not shown in the figure). The first handling robot is used to carry and pick up material boxes between two storage layers 2 or between the temporary storage layer and the storage layer 2; the second handling robot is used to carry / pick up and put material boxes on the temporary storage layer, and the lifting mechanism of the second handling robot can pass through the first channel 5.

[0056] The first handling robot in this embodiment can be a traction-type or forklift-type robot, which can move up and down relative to the shelf with the help of a lifting device, thereby realizing the picking and placing / handling of materials at different heights; the second handling robot is a lurking lifting robot, which runs to the bottom of the temporary storage layer, lifts up the material box on the temporary storage layer through the lifting mechanism, and moves with the material box to realize the handling. Figure 5 and Figure 6 As shown in the figure, the actual handling process is explained by taking two temporary storage layers as an example:

[0057] See attached Figure 5 There are two temporary storage layers under the shelves in the storage system. The dotted lines in the middle represent materials. In this example, the two temporary storage layers are respectively positioned as the first temporary storage layer at a low position and the second temporary storage layer at a high position. In specific operation, the first handling robot first takes down the materials placed on the high storage layer according to the received instructions and places them on the temporary storage layer. When the materials on the first temporary storage layer need to be taken, the operation is similar to that of the shelves with a single temporary layer. After the unloaded second handling robot moves to the bottom of the temporary storage layer, it controls its lifting mechanism to rise to a height of H1. H1 enables the lifting mechanism to pass through the first channel and lift the materials on the first temporary storage layer. Then the second handling robot keeps the lifting state and moves forward through the first channel to leave the first temporary storage layer area and move the materials on the first temporary layer to the destination. When it is necessary to take materials on the second temporary storage layer (at this time, it is necessary to ensure that there is no material on the first temporary storage layer directly below the second temporary storage layer), the second handling robot also first moves to the bottom of the temporary storage layer, and then the lifting mechanism rises to a height of H2 (H2>H1). H2 enables the lifting mechanism to pass through the first channels on the first temporary storage layer and the second temporary storage layer in turn and lift the materials on the second temporary layer. Then the second handling robot maintains the lifting state and moves forward through the first channel to leave the second temporary storage layer area. The lifting mechanism descends to reduce its height from H2 to H1, and then maintains the height of H1 to move the materials to the destination.

[0058] When materials need to be placed on the second temporary storage layer (at this time, it is necessary to ensure that there is no material on the first temporary storage layer directly below the second temporary storage layer), the second handling robot first moves to the position corresponding to the temporary storage layer when the jacking mechanism is at the height of H1, then raises the jacking mechanism to H2, and then passes through the first channel to place the materials on the second temporary storage layer. The jacking mechanism contracts, so that the materials fall on the second temporary storage layer under the action of their own weight.

[0059] It can be seen that the multi-layer temporary storage layer structure combined with the design of the first channel will not affect the work of the handling robot. The multi-layer temporary storage layer structure greatly increases the number of temporary storage layers, and can match the design of the storage shelf structure with more storage layers in terms of efficiency, thereby improving the handling efficiency.

[0060] The present application sets a first channel 5 and a second channel 9, which can optimize the motion path of the transport robot and improve the transport efficiency. Figure 6 , where W1 is a temporary storage layer with a first channel 5. When materials need to be taken or stored at W1, the path of the second robot is shown by the solid arrow in the middle. The second robot moves from the second channel 9 to W1, and then passes through the first channel 5 and continues to move forward to the third channel 10 (the third channel 10 is the channel between two adjacent rows of shelves). The entire path is a one-way path; in the figure, W2 is a temporary storage layer without a first channel 5. When materials need to be taken or stored at W2, the path of the second robot is shown by the dotted arrow in the middle. The second robot moves from the second channel 9 to W2, and then moves to the bottom of W2 to place materials or take materials, and then retreats and enters the second channel 9 again for transportation. It can be seen that it cannot pass through W2 for transportation. During the retreat process, it may cause congestion in the operation of other robots at the second channel 9. During the peak period of transportation, the congestion is particularly serious, which greatly affects the transportation efficiency.

[0061] It can be seen that by setting up the first channel 5, the detour of the second transport robot can be reduced, and at the same time, the occupancy of the third channel 10 by the second transport robot can be reduced, which can significantly reduce the congestion of the transport robot and effectively improve the transport efficiency.

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.
