Description

Technical Field

[0001] This application relates to the field of warehousing technology, and in particular to a rack-supporting comb and a cargo handling vehicle. Background Technology

[0002] In warehouses, goods are typically moved manually or using automated guided vehicles (AGVs). The AGV inserts its teeth under the goods, then raises the teeth to remove the goods from the shelf and transport them to their destination. During this process, goods may slide on the teeth or even fall off due to inertia and AGV vibration. When using AGVs, this sliding can affect the AGV's ability to pinpoint the goods' location, consequently impacting the accuracy of their placement after transport. Utility Model Content

[0036] The features and exemplary embodiments of various aspects of this application will now be described in detail. Numerous specific details are set forth in the following detailed description in order to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without some of these specific details. The following description of embodiments is merely intended to provide a better understanding of this application by illustrating examples thereof.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The embodiments will now be described in detail with reference to the accompanying drawings.

[0038] Relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0039] It should be understood that when describing the structure of a component, when referring to a layer or region as being "above" or "on top of" another layer or region, it can mean that it is directly above the other layer or region, or that it contains other layers or regions between it and the other layer or region. Furthermore, if the component is flipped over, that layer or region will be located "below" or "under" the other layer or region.

[0040] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0041] It should be understood that in the embodiments of this application, "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean that B is determined solely based on A; B can also be determined based on A and / or other information.

[0042] The applicant discovered that when using a freight forwarding vehicle to move goods, the vehicle inserts its comb teeth under the goods on the shelf, lifts the goods, removes them from the shelf, and uses the comb teeth to support them, moving them to the target location and placing them on the shelf or platform there. Considering the varying sizes of the goods, when the width of the goods is less than the length of the comb teeth, the goods may slide on the comb teeth due to inertia as the vehicle moves and the vehicle vibrates or shakes. This sliding can cause goods to slip off the comb teeth and fall, resulting in damage. When the freight forwarding vehicle is automated, this sliding will cause a deviation between the actual and theoretical positions of the goods, affecting the accuracy of their placement at the target location.

[0043] Based on the above analysis, the applicant proposes a rack-supporting comb and a cargo handling vehicle. The rack-supporting comb includes a connecting portion, comb teeth, and a first protrusion. The connecting portion extends along a first direction and is used to connect with the moving part of the cargo handling vehicle. The comb teeth extend along a second direction and are arranged along the first direction. When handling goods, the comb teeth extend under the goods on the warehouse rack, and lifting the rack-supporting comb of this embodiment can remove the goods from the warehouse rack. The first protrusion is connected to the end of the comb teeth away from the connecting portion along the second direction, and the first protrusion protrudes from the step bearing surface. One end of the bottom surface of the goods can abut against the connection between the first protrusion and the step bearing surface, and the bottom surface of the goods will be supported by one of the sub-bearing surfaces of the step bearing surface. At this time, goods of different sizes will be supported by the corresponding sub-bearing surfaces, and the movement of goods along the second direction can be restricted by the corresponding stop surfaces, thereby reducing the possibility of goods sliding on the step bearing surface.

[0044] Figure 1 This is a schematic diagram of a shelf-supporting comb tooth structure according to an embodiment of this application. Figure 2 This is a side view of the shelf-supporting comb teeth along a first direction, according to an embodiment of this application. Figure 3 This is a schematic diagram of a structure used in an embodiment of this application when a shelf supports goods with comb teeth. Figure 4 This is another structural diagram of a shelf using the embodiments of this application to support goods with comb teeth. Figure 5 This is another structural diagram of a shelf using the embodiments of this application to support goods with comb teeth.

[0045] Please see Figures 1 to 5This application provides a shelf support comb, including: a connecting part 1 extending along a first direction D1; a plurality of comb teeth 2 extending along a second direction D2, the plurality of comb teeth 2 arranged along the first direction D1, the first direction D1 and the second direction D2 intersecting, one end of the comb teeth 2 along the second direction D2 being connected to the connecting part 1; the comb teeth 2 including a stepped bearing surface 21, at least a portion of the stepped bearing surface 21 extending along the second direction D2; the stepped bearing surface 21 including a plurality of sub-bearing surfaces 211 and a stop surface 212, two adjacent sub-bearing surfaces 211 along the second direction D2 being connected by a stop surface 212, at least one sub-bearing surface 211 being parallel to the second direction D2, and the stop surface 212 intersecting the second direction D2; a plurality of first protrusions 3, the plurality of first protrusions 3 being respectively connected to different ends of the comb teeth 2 along the second direction D2 away from the connecting part 1, the first protrusions 3 protruding from the stepped bearing surface 21.

[0046] In this embodiment, the first direction D1, the second direction D2, and the third direction D3 intersect each other in pairs. For ease of understanding, this embodiment is illustrated by the example that the three directions can be perpendicular to each other in pairs. When the rack-supporting comb teeth of this embodiment are placed on a horizontal plane, the first direction D1 and the second direction D2 can be two mutually perpendicular horizontal directions, and the third direction D3 can be a vertical direction.

[0047] The shelf-mounted comb teeth of this embodiment can be installed on a handling device for goods 6, such as a cargo handling vehicle 100, for moving goods 6 on a warehouse shelf. It is understood that goods 6 are typically packaged in the form of a cuboid or cube, so goods 6 can be considered as a cuboid or cube. In addition to moving goods 6, the shelf-mounted comb teeth of this embodiment can also be used to move other cuboid or cube-shaped items.

[0048] The connecting part 1 extends along the first direction D1 and can be used to connect the shelf-carrying comb teeth of this embodiment of the application with an external goods handling device 6, such as a goods handling vehicle 100. The goods handling device 6 can move the connecting part 1 along the third direction D3, so that the shelf-carrying comb teeth of this embodiment of the application can rise or fall to lift or place the goods 6.

[0049] The comb teeth 2 extend along the second direction D2, and multiple comb teeth 2 are arranged along the first direction D1 and connected to the connecting part 1. The comb teeth 2 include a stepped bearing surface 21, which can be regarded as multiple sequentially connected folded surfaces similar to a step, including sub-bearing surfaces 211 and stop surfaces 212. The sub-bearing surfaces 211 and stop surfaces 212 are alternately connected to form the stepped bearing surface 21. It should be noted that along the third direction D3, the comb teeth 2 also have a back surface opposite to the stepped bearing surface 21. Along the second direction D2 away from the connecting part 1, the minimum distance between the multiple sub-bearing surfaces 211 and the back surface gradually decreases.

[0050] When removing goods 6 from the warehouse shelf, the comb teeth 2 can be inserted under the goods 6 by moving the connecting part 1, and the goods 6 can be lifted and removed from the warehouse shelf. At this time, the step bearing surface 21 of the comb teeth 2 supports the bottom surface of the goods 6. For goods 6 with a fixed size, one of the sub-bearing surfaces 211 of the step bearing surface 21 contacts the bottom surface of the goods 6, providing support for the goods 6. Under the action of gravity, the movement of the goods 6 relative to the shelf bearing comb teeth of this embodiment along the third direction D3 can be restricted.

[0051] A portion of the comb teeth 2 have a first protrusion 3 connected to one end of the comb teeth 2 away from the connecting portion 1 along the second direction D2. The first protrusion 3 protrudes from the step bearing surface 21 along the third direction D3. For a cargo 6 of a fixed size, when a certain sub-bearing surface 211 of the step bearing surface 21 supports the cargo 6, the first protrusion 3 can restrict the cargo 6 from moving away from the connecting portion 1 relative to the comb teeth 2 along the second direction D2. At the same time, since the size of the cargo 6 is fixed, the stop surface 212 on the side of the sub-bearing surface 211 corresponding to the cargo 6 of that size near the connecting portion 1 can restrict the cargo 6 from moving towards the connecting portion 1 relative to the comb teeth 2 along the second direction D2. Therefore, through the cooperation of the first protrusion 3 and the stop surface 212, the movement of the cargo 6 relative to the shelf bearing comb teeth of this embodiment along the second direction D2 can be restricted. Furthermore, considering that the distance between the stop surface 212 on the side of the multiple sub-supporting surfaces 211 near the connecting part 1 and the first protrusion 3 is different, goods 6 of different sizes can be supported by the corresponding sub-supporting surfaces 211, and their movement relative to the shelf support comb teeth of this application embodiment along the second direction D2 is restricted by the first protrusion 3 and the corresponding stop surface 212. Therefore, when using the shelf support comb teeth of this application embodiment to transport goods 6 of different sizes, the shelf support comb teeth of this application embodiment can reduce the possibility of goods 6 of different sizes sliding on the shelf support comb teeth of this application embodiment.

[0052] It is understood that when using the rack-carrying comb of the present application embodiment to transport goods 6 of different sizes, the second direction D2 usually corresponds to the forward or backward direction of the transport equipment connected to the rack-carrying comb of the present application embodiment. Therefore, when transporting goods 6, the rack-carrying comb of the present application embodiment and goods 6 are more likely to slide relative to each other along the second direction D2. Therefore, the first protrusion 3 and the corresponding stop surface 212 provided along the second direction D2 are sufficient to limit the relative sliding between goods 6 and rack-carrying comb of the present application embodiment.

[0053] Furthermore, for a given sub-supporting surface 211, the distance between the stop surfaces 212 on both sides of the sub-supporting surface 211 along the extension direction of the sub-supporting surface 211 and the first protrusion 3 corresponds to the upper and lower limits of the size of the goods 6 that the sub-supporting surface 211 can support. Therefore, multiple stop surfaces 212 can each correspond to multiple boundary dimensions, dividing the size of the goods 6 into multiple size ranges according to the boundary dimensions. When the size of a certain goods 6 falls within a certain size range, the corresponding sub-supporting surface 211 can support the goods 6.

[0054] Figure 6 Another side view of the shelf-supporting comb teeth along a first direction using an embodiment of this application.

[0055] Further, please refer to Figure 6 and combined Figures 1 to 5 Among the multiple sub-supporting surfaces 211, the sub-supporting surface 211 that is close to the connecting part 1 along the second direction D2 is parallel to the second direction D2, and the planes where two adjacent sub-supporting surfaces 211 along the second direction D2 are located intersect or are parallel.

[0056] Among the multiple sub-supporting surfaces 211, the sub-supporting surface 211 closest to the connecting part 1 along the second direction D2 corresponds to the largest lower limit of the cargo 6 size range, so the sub-supporting surface 211 can support the largest lower limit of cargo 6 size. Considering that the larger the size of cargo 6, the greater the likelihood of its weight, the sub-supporting surface 211 should be able to provide stable support for cargo 6. Since the sub-supporting surface 211 is parallel to the second direction D2 (approximately parallel to the horizontal direction), the supporting force provided by the sub-supporting surface 211 to cargo 6 is approximately equal to the weight of cargo 6. If the sub-supporting surface 211 is inclined relative to the second direction D2, the supporting force provided by the sub-supporting surface 211 to cargo 6 will be less than the weight of cargo 6, reducing the maximum static friction between the sub-supporting surface 211 and cargo 6. Since the sub-supporting surface 211 also applies static friction to cargo 6 to keep cargo 6 stationary relative to the sub-supporting surface 211, it is easier for cargo 6 to slide. Therefore, the sub-bearing surface 211 is parallel to the second direction D2, which can reduce the sliding of the goods 6 relative to the shelf bearing comb provided in the embodiment of this application along the second direction D2.

[0057] Among the multiple sub-bearing surfaces 211, the lower limit of the size range of the goods 6 corresponding to the other sub-bearing surfaces 211 is smaller, the size of the corresponding goods 6 is smaller, and the weight of the goods 6 is more likely to be smaller. When the other sub-bearing surfaces 211 are inclined or parallel to the second direction D2, the corresponding goods 6 can abut against the corresponding stop surface 212. Inclined sub-bearing surfaces 211 can keep the goods 6 in abutting state with the stop surface 212, thereby reducing the possibility that the goods 6 will slide relative to the shelf bearing comb teeth provided in this application embodiment along the second direction D2.

[0058] Further reading Figure 6 and combined Figures 1 to 5 Among the multiple sub-supporting surfaces 211, the acute angle between the sub-supporting surface 211 and the second direction D2 gradually increases along the direction away from the connecting part 1 in the second direction D2.

[0059] If all the sub-supporting surfaces 211 are parallel to the second direction D2, then in order to prevent interference between the sub-supporting surfaces 211, along the second direction D2, from the first protrusion 3 to the connecting part 1, the distance between the sub-supporting surfaces 211 and the back of the comb tooth part 2 gradually increases. When the number of sub-supporting surfaces 211 is too large, the total thickness of the comb tooth part 2 along the third direction D3 is large, which will significantly increase the total weight and production cost of the comb tooth part 2.

[0060] By tilting multiple sub-supporting surfaces 211 relative to the second direction D2, and with the acute angle between the sub-supporting surfaces 211 and the second direction D2 gradually increasing along the direction away from the connecting part 1, the step support surface 21 can be approximately sawtooth-shaped without interference between the sub-supporting surfaces 211. Therefore, the thickness of the comb tooth portion 2 along the third direction D3 is more uniform, reducing the difference between the maximum and minimum thickness. This results in a more complex shape for the step support surface 21 of the comb tooth portion 2 without significantly increasing the total weight and production cost. Furthermore, under gravity, the goods 6 supported by the tilted sub-supporting surfaces 211 will remain in contact with the stop surface 212, thereby reducing the sliding of the goods 6 relative to the shelf support comb teeth provided in this embodiment along the second direction D2.

[0061] Further reading Figure 6 and combined Figures 1 to 5 The connection between the first protrusion 3 and the step bearing surface 21 is coplanar with each sub-bearing surface 211. Therefore, when a sub-bearing surface 211 supports the goods 6, if the goods 6 is subjected to a large external force, it will slide relative to the sub-bearing surface 211 along the second direction D2, disengaging from the stop surface 212 until the bottom corner of the goods 6 abuts against the connection between the first protrusion 3 and the step bearing surface 21, thus limiting the goods 6 and preventing further sliding. Even if the sliding of the goods 6 relative to the shelf bearing comb provided in this embodiment along the second direction D2 is reduced, the risk of the goods 6 slipping off the shelf bearing comb provided in this embodiment can be reduced.

[0062] Further reading Figure 6 and combined Figures 1 to 5The sub-supporting surface 211 has a chamfered surface at the connection point with the stop surface 212 on the side away from the connecting part 1 along the second direction D2. When using the shelf-supporting comb teeth of this embodiment to remove goods 6 from the warehouse shelf, if the goods 6 are small in size and are initially supported by the sub-supporting surface 211 near the connecting part 1, then when the goods 6 slides relative to the shelf-supporting comb teeth of this embodiment, the goods 6 will slide from one sub-supporting surface 211 to another. During this process, the goods 6 will slightly slide off the stop surface 212 on the side of the sub-supporting surface 211 away from the connecting part 1 to the adjacent sub-supporting surface 211. The chamfered surface can reduce the intensity of the vibration caused by this slight slip, thereby reducing the risk that the goods 6 will fall directly off the step support surface 21 due to this slight slip.

[0063] Further reading Figure 6 and combined Figures 1 to 5 The first protrusion 3 is provided with a guide surface 31 at one end away from the step bearing surface 21 along the third direction D3. The first direction D1, the second direction D2 and the third direction D3 intersect each other. The guide surface 31 is parallel to the first direction D1 and is inclined relative to the third direction D3 in the direction away from the connecting part 1 along the second direction D2.

[0064] In this embodiment, the first direction D1, the second direction D2, and the third direction D3 intersect each other in pairs. For ease of understanding, this embodiment is illustrated by the example that the three directions can be perpendicular to each other in pairs. When the rack-supporting comb teeth of this embodiment are placed on a horizontal plane, the first direction D1 and the second direction D2 can be two mutually perpendicular horizontal directions, and the third direction D3 can be a vertical direction.

[0065] The guide surface 31 of the first protrusion is located on the side of the first protrusion 3 close to the connecting part 1 along the second direction D2. The guide surface 31 is inclined in the direction away from the connecting part 1 along the second direction D2. During the process of removing the goods 6 from the warehouse shelf using the shelf-bearing comb of the present application embodiment, the guide surface 31 can guide the ground edge of the goods 6, making it easier for the shelf-bearing comb of the present application embodiment to insert under the goods 6, and enabling the goods 6 to be supported by the step bearing surface 21.

[0066] Figure 7 This is a schematic diagram of another structure of the shelf-supporting comb teeth according to an embodiment of this application.

[0067] Further, please refer to Figure 7The shelf-supporting comb teeth also include a plurality of second protrusions 4; among the plurality of comb teeth 2 arranged along the first direction D1, the comb teeth 2 located at both ends along the first direction D1 are respectively connected to at least one second protrusion 4; the second protrusion 4 is located on one side of the comb teeth along the first direction D1; the second protrusion 4 protrudes from the step-supporting surface 21.

[0068] Considering that the second direction D2 corresponds to the forward and backward directions of the handling equipment with the shelf-bearing comb teeth of this application embodiment installed, and the first direction D1 corresponds to the left or right turn direction, during the handling of goods 6, if the handling equipment turns left or right, goods 6 may slide relative to the shelf-bearing comb teeth of this application embodiment along the first direction D1.

[0069] Multiple comb teeth 2 are arranged along the first direction D1. Second protrusions 4 are provided on the comb teeth 2 located at both ends. Since the second protrusions 4 protrude from the step bearing surface 21, they can limit the movement of the goods 6 along the first direction D1, thereby restricting the goods 6 from sliding relative to the shelf bearing comb teeth of this embodiment along the first direction D1 and reducing the possibility of the goods 6 slipping off the shelf bearing comb teeth of this embodiment. It is understood that one second protrusion 4 can be connected to one comb tooth 2, and one second protrusion 4 can also be connected to multiple comb teeth 2.

[0070] Figure 8 This is a schematic diagram of another structure of the shelf-supporting comb teeth according to an embodiment of this application.

[0071] Further, please refer to Figure 8 The shelf-supporting comb teeth also include multiple third protrusions 5; the third protrusions 5 are disposed at one end of the comb tooth portion 2 along the second direction D2 near the connecting portion 1; at least two comb tooth portions 2 are connected to one third protrusion 5, and the third protrusion 5 protrudes out of the step bearing surface 21.

[0072] When the shelf-supporting comb teeth of this embodiment are used to transport goods 6, the connection between the comb teeth 2 and the connecting part 1 will be subjected to a large shear force. When the goods 6 slide relative to the comb teeth 2 along the second direction D2, the goods 6 may collide with the connecting part 1, affecting the connection strength between the connecting part 1 and the comb teeth 2. The third protrusion 5 is provided at the connection between the comb teeth 2 and the connecting part 1, and the third protrusion 5 protrudes from the step bearing surface 21. When the goods 6 slide relative to the comb teeth 2 along the second direction D2, the third protrusion 5 restricts the sliding range of the goods 6 along the second direction D2 toward the connecting part 1, reducing the risk of the goods 6 slipping off the comb teeth 2. During this process, the goods 6 can abut against the third protrusion 5 and distribute the force to various parts of the connecting part 1, thereby reducing the risk of connection failure between the connecting part 1 and the comb teeth 2 due to excessive local force.

[0073] Furthermore, the comb teeth 2 are detachably connected to the connecting part 1, allowing for the installation of a suitable comb teeth 2 before using the shelf-mounted comb teeth of this embodiment to transport goods 6. Since the stop surfaces 212 of the comb teeth 2 can correspond to multiple boundary dimensions, dividing the size of goods 6 into multiple size ranges according to these boundary dimensions, a suitable size range can be determined based on the size of goods 6 before transporting them. This allows for the selection of an appropriate comb teeth 2, which is then installed on the connecting part 1. For goods 6 with a determined size, the goods 6 will slide relative to the comb teeth 2 within the corresponding size range. Therefore, to reduce the sliding range of goods 6, the upper and lower limits of the size range corresponding to goods 6 should not differ too much from the size of goods 6. For example, the difference between the upper and lower limits of the size range corresponding to goods 6 and the size of goods 6 should not exceed 50% of the size of goods 6.

The moving part 102 is movably disposed relative to the cargo carrying support 101 along a third direction D3. The first direction D1, the second direction D2 and the third direction D3 intersect each other. The shelf carrying comb 200 of the aforementioned embodiment of this application is connected to the moving part 102.

[0076] In this embodiment, the transport vehicle 100 can be a manually driven transport vehicle 100 or an intelligently controlled transport vehicle 100 (AGV). The first direction D1 corresponds to the left or right turn direction of the transport vehicle 100, and the second direction D2 corresponds to the forward or backward direction of the transport vehicle 100. The transport vehicle 100 is provided with a cargo-carrying support 101 extending along a third direction D3. The moving part 102 can move relative to the cargo-carrying support 101 along the third direction D3. The moving part 102 is connected to the connecting part 1 of the shelf-carrying comb 200 in the aforementioned embodiment of this application, so that the shelf-carrying comb 200 can move along the third direction D3. In conjunction with the movement of the transport vehicle 100 along the second direction D2 and the rotation or movement towards the first direction D1, the cargo 6 located on the shelf-carrying comb 200 can move along the first direction D1, the second direction D2, and the third direction D3.

[0077] It should be noted that both the warehouse shelf 7 and the shelf at the target location for transporting goods 6 can adopt a comb structure similar to the shelf-supporting comb 200 of the aforementioned embodiments of this application. Taking the warehouse shelf 7 as an example, the comb structure of the warehouse shelf 7 is also arranged along the first direction D1. When the goods 6 is removed from the warehouse shelf using the goods handling vehicle of the present application embodiment, the comb part 2 of the shelf-supporting comb 200 can be inserted into the gap between the comb structures of the warehouse shelf 7, and the goods 6 can be removed from the warehouse shelf 7 by the lifting and moving part 102.

[0078] In summary, this application provides a rack-supporting comb and a cargo handling vehicle. The rack-supporting comb includes a connecting part, comb teeth, and a first protrusion. The connecting part is used to connect with the moving part of the cargo handling vehicle. When the comb teeth are inserted under the cargo, the cargo can be lifted or lowered by the moving part. The stepped bearing surface of the comb teeth can be used to support the cargo. One end of the bottom surface of the cargo can abut against the connection between the first protrusion and the stepped bearing surface. The bottom surface of the cargo is supported by one of the sub-bearing surfaces of the stepped bearing surface. Cargo of different sizes can be restricted from moving in a second direction by corresponding stop surfaces. Therefore, the rack-supporting comb of this application can reduce the possibility of cargo sliding on the stepped bearing surface, thereby reducing the risk of cargo falling.

[0079] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
