Description

Technical Field

[0001] The utility model relates to the technical field of warehousing, in particular to a warehousing shelf and a warehousing system. Background Art

[0002] In the warehousing field, cache locations are generally set at the bottom of the storage shelves as transfer stations to improve the turnover efficiency of the warehouse.

[0003] During actual setting, the location of the cache position needs to ensure that the handling robot can place the goods accurately on the cache position. During installation, it is necessary to ensure that the center line of the cache position corresponds to the center line of the ground mark. In related technologies, when arranging the cache position, it is generally necessary to set the cache position first, and then determine the position of the ground mark based on the position of the cache position. Since the space at the bottom of the shelf is small, the space is even smaller after the cache position is set. At this time, the operator performs ground marking operations at the bottom of the cache position, which is inconvenient to operate. Utility Model Content

[0004] The present invention aims to solve one of the technical problems in the related art to a certain extent. To this end, the present invention provides a storage shelf and a storage system that facilitates adjustment of the position of the cache position and improves the installation efficiency of the cache position and ground signs.

[0005] In order to achieve the above-mentioned purpose, the first aspect of the present invention discloses a storage shelf, comprising a plurality of columns and at least one layer of storage layer plates fixed to the columns, a support portion is provided on the bottom side of the bottom storage layer plates, a cache unit for carrying materials is provided on the support portion, the cache unit is arranged opposite to the bottom storage layer plates, and the position of the cache unit on the support portion is adjustable.

[0006] The position of the cache unit in the present technical solution can be adjusted on the support part. During the adjustment process, the distance between the cache unit and the bottom storage layer plate remains unchanged. In this way, during the installation stage of the storage shelf, a ground mark for identification by the handling robot can be set at the bottom of the storage shelf. At this time, since the cache unit has not been installed yet, the operating space at the bottom of the storage shelf is relatively ample, which is convenient for the operator to work. After the ground mark is arranged, the cache unit can be set. At this time, the ground mark position can be used as the installation reference to adjust the position of the cache unit so that the center position of the cache unit corresponds to the ground mark position. The overall installation is convenient, which can reduce the installation difficulty of the staff and improve the installation efficiency.

[0007] Furthermore, the supporting portion includes at least one supporting member, the cache unit is connected to the storage layer plate of the bottom layer through the at least one supporting member, and the cache unit is movably arranged on the supporting member.

[0008] Furthermore, the cache unit includes two cache trays, each of which is connected to the storage layer plate of the bottom layer through a corresponding support member. The two cache trays in the same cache unit are arranged side by side and together with the corresponding two support members define a storage space.

[0009] Furthermore, the support member includes a connecting beam, a supporting frame arranged on the connecting beam, and a fixed plate arranged on the supporting frame. The storage layer plate includes a cross beam arranged between adjacent columns and a plate body arranged on the cross beam. Connecting plates are respectively provided at both ends of the connecting beam. The connecting beam is fixedly connected to two opposite cross beams through the connecting plates, and the cache tray is detachably connected to the fixed plate.

[0010] Furthermore, the support member includes a connecting beam, a support frame mounted on the connecting beam, and a fixed plate mounted on the support frame. The storage layer includes a crossbeam mounted between adjacent columns, with connecting plates provided at each end of the connecting beam. The connecting beam is fixedly connected to two opposing crossbeams via the connecting plates, and the buffer tray is detachably connected to the fixed plates. The buffer unit is mounted on the storage shelf, reducing floor space. The overall structure of the buffer unit is strong and stable.

[0011] Furthermore, the fixed plate is provided with a first connection hole, and the buffer support plate is provided with a second connection hole corresponding to the first connection hole. The length of the first connection hole along the width direction of the storage space is greater than the diameter of the second connection hole. The buffer support plate is connected to the fixed plate via a support member passing through the first and second connection holes. During installation, the second connection hole can be connected to different positions within the length range of the first connection hole, thereby changing the position of the buffer support plate. The adjustment structure is simple and easy to manufacture and adjust.

[0012] Furthermore, a plurality of the first connection holes and the second connection holes are respectively provided along the direction of materials entering and exiting the storage space, and the plurality of the first connection holes and the second connection holes are distributed at intervals, thereby improving the stability of the installation of the buffer support plate.

[0013] Furthermore, a set distance is formed between the two oppositely disposed buffer trays of the buffer unit, so as to facilitate the transport robot to take and place goods on the buffer trays.

[0014] Furthermore, each of the buffer trays includes inclined plates disposed at both ends thereof and extending obliquely toward the bottom of the buffer tray. The top surface of the buffer tray is provided with a guide plate disposed along the direction of material entry and exit of the storage space. The upper end of the guide plate forms a first guide groove extending obliquely away from the center of the buffer unit, and the two ends of the guide plate along the direction of material entry and exit of the storage space form a second guide groove extending obliquely away from the center of the buffer unit. This guides the materials to be placed on the buffer unit, allowing the goods to be placed smoothly and stably on the two buffer trays.

[0015] Furthermore, the storage shelf has a first direction and a second direction orthogonal to the first direction. The cache units are arranged along the first direction. The length of the cache units along the second direction is less than the length of the storage shelf along the second direction. A first channel is formed on the bottom side of the storage shelf at least at one end of the cache unit along the second direction. Walking space for a handling robot is reserved at the bottom of the storage shelf to improve the turnover efficiency of goods.

[0016] The second aspect of the present application discloses a warehousing system, including a first handling robot and at least one storage shelf disclosed in the first aspect, wherein the first handling robot is used to carry and pick up material boxes for the cache unit.

[0017] Furthermore, there is a height difference between the bottom surface of the cache unit and the bottom surface of the column, and the height difference is greater than the height of the second transport robot when it is empty.

[0018] The reasoning process of the beneficial effects of the storage system provided by the present invention is similar to that of the aforementioned storage shelves, and will not be repeated here.

[0032] The following describes in detail embodiments of the present invention, examples of which 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 explain the present invention and are not to be construed as limiting the present invention.

[0033] 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 appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0034] See attached Figure 1 、 23. One embodiment of the present invention discloses a storage shelf, comprising a plurality of columns 11 and at least one layer of storage layer plates 12 fixed to the columns 11. The storage layer plates 12 are spaced apart along the height direction of the columns 11 and may adopt a plate or frame structure. The storage layer plates 12 are used to store material boxes, cargo boxes, etc. and are generally multi-layered. A plurality of columns 11 are generally supported at the four corners of the storage layer plates 12. Of course, when necessary, such as when the width and length of the shelf are long, in order to ensure the overall strength and stability of the shelf, additional columns 11 may be added in the middle of the length and width directions to improve the supporting effect.

[0035] A support portion is provided on the bottom side of the bottom storage layer plate 12, and a cache unit for carrying materials is provided on the support portion. The cache unit is arranged opposite to the bottom storage layer plate 12, and the position of the cache unit on the support portion is adjustable.

[0036] It should be noted that the adjustable position of the cache unit mentioned in this embodiment means that the position of the cache unit at the bottom of the storage shelf is adjustable in the horizontal direction. During the adjustment process, the position of the cache unit in the height direction remains unchanged. In actual settings, it can be the overall position adjustment of the cache unit or the position adjustment of a specific component on the cache unit. It is only necessary to ensure that the position of the component for storing materials on the cache unit is adjustable, and no special limitation is made here.

[0037] See attached Figure 1 When the storage shelves are installed, the ground marker 40 is generally fixed on the same base surface as the column 11. The handling robot moves to the set position corresponding to the cache unit through its own navigation and the ground marker 40. The ground marker 40 generally needs to correspond to the center line of the storage space of the storage material of the cache unit to ensure that the robot can accurately place the material on the cache unit.

[0038] In the installation stage of the storage shelves in this embodiment, the operator can first set a ground mark 40 for the handling robot to identify at the bottom of the storage shelf. Since the cache unit at the bottom of the storage shelf has not been installed at this time, the operable space at the bottom of the storage shelf is relatively ample, which is convenient for the operator to arrange the ground mark 40 and improve the arrangement efficiency of the ground mark 40. After the ground mark 40 is arranged, the cache unit is set so that the center position of the cache unit corresponds to the position of the ground mark 40. The overall installation is convenient, which can reduce the installation difficulty of the staff and improve the installation efficiency.

[0039] This embodiment does not specifically limit the structure and position of the support part. The support part can be a separate component or the bottom storage layer plate 12. That is, the position of the cache unit on the bottom side of the bottom storage layer plate 12 is not specifically limited. Specifically, it can be connected to the bottom of the storage layer plate 12 or the column 11, or it can be fixed on the ground or the base surface.

[0040] As one of the embodiments of the present invention, the support portion includes at least one support member, the cache unit is connected to the storage layer plate of the bottom layer through at least one support member, and the cache unit is movably arranged on the support member 21.

[0041] See attached Figure 2 、 3 The cache unit in this embodiment is hung on the storage layer plate 12 through the support member 21, which can reduce the footprint of the cache unit. In actual settings, the support member 21 in this embodiment can also be fixed to other parts of the storage shelf, such as the column 11.

[0042] In actual use, the cache unit is movably arranged on the support member. When in use, the position of the cache unit on the support member is adjusted according to the position of the ground code mentioned above.

[0043] It is conceivable that the position of the cache unit in this embodiment can be adjusted by adjusting the position of the support 21, or by adjusting the position of the cache unit on the support 21. Of course, in actual settings, both can have adjustment functions at the same time. In actual design, multiple connecting holes arranged side by side are generally designed on the storage shelf. The support can be connected to different connecting holes to achieve adjustment between different positions of the cache unit. During assembly, the installation of the support 21 can be used as a coarse adjustment of the cache unit position. In combination with the adjustable position of the cache support plate 31, a wider range and more accurate position can be achieved. Increasing the adjustability of the cache unit, having a larger adjustment range, and easy operation.

[0044] In this embodiment, there is no specific limitation on the specific structure of the cache unit, as long as it can store goods and its position can be adjusted.

[0045] As one of the embodiments of the present invention, see the attached Figure 4 The cache unit includes two cache trays 31. Each cache tray 31 is connected to the bottom storage layer 12 via a corresponding support member 21. The two cache trays 31 in the same cache unit are arranged side by side and, together with the corresponding two support members 21, define a storage space. The cache unit in this embodiment supports materials via the two cache trays 31.

[0046] Furthermore, the support member 21 includes a connecting beam 211, a support frame 212 arranged on the connecting beam 211, and a fixed plate 213 arranged on the support frame 212. The storage layer plate 12 includes a beam 13 arranged between adjacent columns 11 and a plate body arranged on the beam 13. Connecting plates are respectively provided at both ends of the connecting beam 211. The connecting beam 211 is fixedly connected to the two opposite beams 13 through the connecting plates. The cache support plate 31 is detachably connected to the fixed plate 213.

[0047] As one of the embodiments of the present invention, the support member 21 includes a connecting beam 211, a support frame 212 provided on the connecting beam 211, and a fixed plate 213 provided on the support frame 212. The storage shelf includes a crossbeam 13 provided between adjacent columns 11. Connecting plates are provided at both ends of the connecting beam 211. The connecting beam 211 is fixedly connected to two opposite crossbeams 13 through the connecting plates. The buffer support plate 31 is detachably connected to the fixed plate 213. The support member 21 in this embodiment is fixed to the crossbeam 13 of the storage shelf and is hung at the bottom of the storage shelf. See the attached drawings. Figure 1 、 2 In this way, the cache unit does not need to occupy ground space, and can leave more room for robots walking on the warehouse floor, which is convenient for the robot's path planning. It has high strength, and the support member 21 is a frame structure as a whole, which has high strength and can meet the storage needs of materials of a certain weight.

[0048] See attached Figure 5 、 6 In order to facilitate the adjustment of the position of the cache support plate 31 on the support member 21, a first connecting hole 214 is provided on the fixed plate 213 of one embodiment of the present invention, and a second connecting hole 312 corresponding to the first connecting hole 214 is provided on the cache support plate 31. The length of the first connecting hole 214 along the width direction of the storage space is greater than the aperture of the second connecting hole 312. The cache support plate 31 is connected to the fixed plate 213 through a support member passing through the first connecting hole 214 and the second connecting hole 312.

[0049] This embodiment is provided with a fixing plate 213 connected to the support member 21, and the buffer support plate 31 is fixed on the fixing plate 213, which can improve the stability of the installation of the buffer support plate 31. In addition, a first connection hole 214 is provided on the fixing plate 213, and a second connection hole 312 is provided on the buffer support plate 31. The fixing plate 213 and the buffer support plate 31 are fixedly connected by a support member passing through the first connection hole 214 and the second connection hole 312, which facilitates assembly and disassembly. In addition, the length of the first connection hole 214 in this embodiment is greater than the diameter of the second connection hole 312. Therefore, during installation, the buffer support plate 31 can adjust the connection position with the fixing plate 213 through the second connection hole 312, thereby adjusting the position of the buffer support plate 31. The position adjustment direction of the buffer support plate 31 is shown in the attached figure. Figure 6 As shown in the direction of the arrow in FIG, the position adjustment structure of the buffer support plate 31 in this embodiment is simple, which facilitates the production of each component and improves the convenience of adjustment.

[0050] In actual installation, the first connection holes 214 can be configured as waist-shaped holes, rectangular holes, or other shapes with a large aspect ratio. Multiple first connection holes 214 are spaced apart along the length of the buffer support plate 31. Waist-shaped holes are easy to manufacture, and the distribution of multiple first connection holes 214 provides multiple connection points along the length of the buffer support plate 31, achieving multi-point support and improving the stability of the installation of the adjustable buffer support plate 31.

[0051] Each support member 21 in this embodiment is independent of each other and can be independently installed at the bottom of the storage shelf. The installation and adjustment on the storage shelf are more flexible. When two adjacent support members 21 are installed, the distance between them can also be adjusted during assembly to adapt to the storage of material boxes of different widths. This makes installation more convenient and adjustment more convenient.

[0052] It can be seen that compared with the fixed structure cache unit in the prior art, the cache unit in the present invention has certain adjustability and is more flexible. During actual use, it can also be further adjusted according to actual conditions to meet more possible working conditions.

[0053] In one embodiment of the present invention, a set distance is formed between the two cache trays 31 of each cache unit, and the set distance is greater than the width of the lifting mechanism of the transport robot. When taking and placing materials from the cache unit, the lifting mechanism of the robot can pass through the set distance.

[0054] When adjusting the position of the buffer tray 31, the set spacing between the two buffer trays 31 in the same buffer unit can remain unchanged. Because the two buffer trays 31 in the same buffer unit can be adjusted simultaneously, maintaining the spacing between the two buffer trays 31 while adjusting the center position of the buffer unit allows the buffer trays 31 to better support the cargo, avoiding the problem of poor material support stability or even failure to support the cargo due to excessive or insufficient spacing caused by adjusting the position of the buffer trays 31.

[0055] Of course, in actual settings, when adjusting the positions of the two buffer trays in the same buffer unit, the set spacing can be changed within a certain range of values, as long as the handling robot can normally pick up and place materials. Moreover, the adjustable set spacing can also meet the storage needs of materials of different sizes.

[0056] As one embodiment of the present invention, each buffer tray includes inclined plates at both ends thereof that extend obliquely toward the bottom of the buffer tray. The top surface of the buffer tray is provided with a guide plate arranged along the direction of material entering and exiting the storage space. The upper end of the guide plate forms a first guide groove 321 that extends obliquely away from the center of the buffer unit, and the two ends of the guide plate along the direction of material entering and exiting the storage space form a second guide groove 322 that extends obliquely away from the center of the buffer unit. This guides the materials to be placed on the buffer unit, allowing the goods to be placed smoothly and stably on the two buffer trays.

[0057] The cam 32 is provided with a plurality of guide plates 312, 313 and 324, which are provided at the top and bottom of the buffer plate 31. The guide plates 32 are provided at the top and bottom of the buffer plate 31. The guide plates 32 are provided at the top and bottom of the buffer plate 31. The guide plates 32 are provided at the top and bottom of the buffer plate 31. The guide plates 32 are provided at the top and bottom of the buffer plate 31.

[0058] The storage shelf of one embodiment of the present invention has a first direction and a second direction orthogonal to the first direction, the support members 21 are arranged along the first direction, the length of the cache pallet 31 along the second direction is smaller than the length of the storage shelf along the second direction, and at least one end of the cache pallet 31 along the second direction is formed with a first channel on the bottom side of the storage layer 12 of the bottom layer of the storage shelf, and the first channel is used for the transport robot to pass through the bottom of the storage shelf.

[0059] In this embodiment, the first direction is generally set as the length direction of the storage shelf, and the second direction is set as the width direction of the storage shelf. In actual layout, the first channel can enable the handling robot to pass through the bottom of the storage shelf under a full load state, which can effectively utilize the space at the bottom of the storage shelf, avoid the interference caused by the movement of a large number of handling robots outside the shelf, and effectively increase the storage capacity. Figure 2 , the handling robot can carry goods and walk at the bottom of the storage shelves, and Figure 2 Place or take out materials from the buffer unit in the direction of the arrow.

[0060] A second aspect of the present application discloses a warehousing system, comprising a first handling robot and at least one storage shelf disclosed in the first aspect, wherein the first handling robot is used to carry a material retrieval box to the buffer unit. Of course, the system may also include a second handling robot, which can be used to carry a material retrieval box between two storage shelves 12 or between a buffer unit and a storage shelf 12.

[0061] Furthermore, a height difference is defined between the bottom surface of the buffer unit and the bottom surface of the column, and the height difference is greater than the height of the second transport robot when it is unloaded. This embodiment reserves walking space for the transport robot at the bottom of the storage shelf, which can be used by the unloaded robot to pass through, thereby improving the turnover efficiency of goods.

[0062] The reasoning process of the beneficial effects of the warehousing system provided in this embodiment is similar to that of the aforementioned warehousing shelves, and will not be repeated here.

[0063] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
