Abstract
Description
Technical Field
[0001] The utility model generally relates to the technical field of intelligent warehousing, in particular to a shelf and a warehousing system. Background Art
[0002] Among the existing automatic guided vehicles, some automatic guided vehicles need to cooperate with tracks to run. Usually, the wheels of the automatic guided vehicles are set to have a flash structure on the side to limit the lateral movement of the automatic guided vehicle and prevent the automatic guided vehicle from derailing.
[0003] However, when an AGV that can switch between different tracks, an avoidance space needs to be set on the track to allow the wheel's flash structure to pass through. However, the avoidance space on the track causes the track to be discontinuous and cannot achieve seamless connection. When the AGV passes through the discontinuous position of the track, it will collide and generate a lot of noise. In some cases where the avoidance space is large, it is necessary to increase the number of wheels on the AGV to prevent the wheels of the AGV from falling into the avoidance space. On the other hand, the avoidance space will also cause stress to be concentrated at the position where the track is discontinuous, which is prone to structural damage on the track.

[0053] The following describes embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0054] Figure 1 The structure of the shelf 10 in the embodiment of the utility model is shown. Figure 2 and Figure 3 The structure of the first sub-track 120 in the first track 12 in the embodiment of the utility model is shown below. Figure 1-Figure 3 The shelf 10 will be described.
[0055] like Figure 1 As shown, the shelf 10 includes a column 11 and a first track 12. The column 11 is arranged in a vertical direction, and one end is supported on the ground. Preferably, a larger supporting surface can be provided at the end of the column 11 supported on the ground to reduce local pressure. The other end of the column 11 extends upward, and the length of the column 11 can be selected according to the height of the warehouse, the structural strength of the material of the column 11, or the upper limit height of the stacking of goods.
[0056] The first track 12 is arranged on the column 11 and extends along the horizontal plane. In the shelf 10, one first track 12 or multiple first tracks 12 may be arranged. When the shelf 10 is provided with multiple first tracks 12, the extension directions of the multiple first tracks 12 are parallel to each other. In this embodiment, each first track 12 includes two mutually parallel first sub-tracks 120. The two mutually parallel first sub-tracks 120 may be arranged symmetrically with respect to the center line of the first track 120. The automatic guided vehicle 20 is arranged to be able to move along the two mutually parallel first sub-tracks 120.
[0057] Figure 2 and Figure 3 The structure of one of the first sub-tracks 120 is shown below. Figure 2 and Figure 3The first sub-track 120 is described below. Another first sub-track 120 in the first track 12 is symmetrically arranged and will not be described in detail.
[0058] like Figure 2 and Figure 3 As shown, the first sub-track 120 includes a first bearing surface 121 and a first limiting portion 122. The first bearing surface 121 is in a horizontal plane, for example, along the extension direction of the sub-track 120, and the first bearing surface 121 is a strip with a fixed width. The first wheel 21 in the automatic guided vehicle 20 can be pressed on the first bearing surface 121, and the first wheel 21 is driven to rotate, and the automatic guided vehicle 20 moves along the first bearing surface 121.
[0059] The first limiting portion 122 is located at the edge of the first bearing surface 121 and protrudes from the first bearing surface 121. The first limiting portion 122 can limit the movement direction of the first wheel 21. In this embodiment, the first limiting portion 122 is located at a side edge of the first bearing surface 121. The first limiting portion 122 can be set on a side close to each other in two mutually parallel first sub-rails 120 in the same first rail 12, or can be set on a side far away from each other in two mutually parallel first sub-rails 120 in one first rail 12. The first limiting portion 122 is set on a side edge of the first bearing surface 121, which is conducive to simplifying the structure of the first sub-rail 120, reducing the weight of the first sub-rail 120, and improving the bearing capacity of the shelf 10. The processing process is simpler, for example Figure 2 As shown in , the first sub-rail 120 can be formed by rolling or stamping a metal sheet, or by bending, and the cost of batch production by mold opening is low.
[0060] In this embodiment, the first limiting portion 122 is used to limit the movement direction of the automatic guided vehicle 20 along the first track 12. In one first track 12, the two first limiting portions 122 in two mutually parallel first sub-tracks 120 can be located at the outer edge or inner edge of the first wheels 21 on both sides of the automatic guided vehicle 20. The movement direction of the automatic guided vehicle 20 can be limited by the structural strength of the automatic guided vehicle 20 itself.
[0061] The automatic guided vehicle 20 that cooperates with the shelf 10 in this embodiment does not need to be provided with a flash structure on the first wheel 21, and the first track 12 does not need to be provided with an avoidance space. The continuity of the first track 12 is better, and there will be no stress concentration, which is conducive to improving the stability of the automatic guided vehicle 20 when moving on the first track 12, reducing collisions and noise. At the same time, there is no need to set more first wheels 21. In some embodiments of the utility model, four first wheels 21 are set in the direction along the first track 12 to ensure that the automatic guided vehicle 20 can be placed stably. In addition, the structure of the first track 12 is simple, which is conducive to reducing weight, simplifying the installation process, and reducing production costs.
[0062] like Figure 1 As shown, in a preferred embodiment of the present utility model, the shelf 10 further includes a second track 13, Figure 4 and Figure 5 The structure of the second track 13 in some embodiments of the present invention is shown below. Figure 1 , Figure 4 and Figure 5 The second rail 13 will be described.
[0063] like Figure 1 As shown, the second track 13 is arranged on the column 11, and the second track 13 is arranged to intersect the first track 12 vertically in the horizontal plane, and the automatic guided vehicle 20 can move along the second track 13. Furthermore, the automatic guided vehicle 20 can also switch between the first track 12 and the second track 13, so that the automatic guided vehicle 20 can move in different directions and cover different positions in the horizontal plane. The second track 13 can cover a larger range in the horizontal plane, further improve the space utilization, and help reduce the number of automatic guided vehicles 20. In this embodiment, the second track 13 includes two second sub-tracks 130 parallel to each other, and the automatic guided vehicle 20 can overlap on the two second sub-tracks 130 parallel to each other and move along the second sub-tracks 130.
[0064] like Figure 4 and Figure 5 As shown, the second sub-track 130 includes a second bearing surface 131 and a second limiting portion 132. The second bearing surface 131 is also in the horizontal plane, and the second wheel 22 in the automatic guided vehicle 20 can be pressed on the second bearing surface 131. When the second wheel 22 is driven to rotate, the automatic guided vehicle 20 can move along the second bearing surface 131. On the automatic guided vehicle 20, the axial direction of the first wheel 21 and the axial direction of the second wheel 22 are perpendicular to each other. The automatic guided vehicle 20 can be configured to control the height of the first wheel 21 and the second wheel 22, so that the automatic guided vehicle 20 can switch between the first track 12 and the second track 13, thereby changing the movement direction of the automatic guided vehicle 20.
[0065] The second limiting portion 132 is located at the edge of the second bearing surface 131 and protrudes from the second bearing surface 131. The second limiting portion 132 can limit the movement direction of the second wheel 22. In this embodiment, the second sub-track 130 can be configured to have a substantially similar structure to the first sub-track 120.
[0066] The second limiter 132 is located at one side edge of the second bearing surface 131. The second limiter 132 can be arranged on the side close to each other in two mutually parallel second sub-rails 130 in the same second rail 13, or can be arranged on the side far away from each other in two mutually parallel second sub-rails 130 in the same second rail 13. The second sub-rails 130 can also be formed by rolling or stamping metal sheets, or by bending. The cost of batch production by mold opening is low, which is conducive to weight reduction.
[0067] According to a preferred embodiment of the present invention, the first bearing surface 121 and the second bearing surface 131 are arranged in the same horizontal plane to improve the running stability of the automatic guided vehicle 20 and reduce bumps and collisions. Figure 5 As shown, a connecting notch 133 is formed on the second limiting portion 132 , so that the first wheel 21 of the automatic guided vehicle 20 can cross the second limiting portion 132 from the position of the connecting notch 133 .
[0068] During the movement of the automatic guided vehicle 20, due to different destinations or different planned routes, at the intersection of the first track 12 and the second track 13, the automatic guided vehicle 20 may change direction, or continue to move in the current direction without changing direction. The connection gap 133 is provided to enable the first wheel 21 of the automatic guided vehicle 20 to pass smoothly, and the first bearing surface 121 and the second bearing surface 131 are on the same horizontal plane, so the automatic guided vehicle 20 can pass directly. Preferably, the width of the second limiting portion 132 is filled at the position of the connection gap 133 to narrow the gap between the first bearing surface 121 and the second bearing surface 131.
[0069] like Figure 6 and Figure 7 As shown, in the embodiment of the present utility model, the first track 12 can be configured to be cut off by the second track 13, and other tracks or other first tracks 12 can be connected on both sides of the first track 12, which will be described in detail in the subsequent embodiments. Figure 6 and Figure 7 As shown in , when the automatic guided vehicle 20 moves along the first track 12 , the first wheel 21 moves from the first bearing surface 121 to the second bearing surface 131 , and crosses the second limiting portion 132 from the position of the connecting gap 133 , and continues to move along the direction of the first track 12 .
[0070] Specifically, according to a preferred embodiment of the utility model, the first sub-rail 120 is arranged at intervals between two mutually parallel second sub-rails 130. A plurality of second rails 13 may be arranged on the shelf 10. A first sub-rail 120 is arranged between two mutually parallel second sub-rails 130 in each second rail 13, and the directions of the first sub-rails 120 arranged inside adjacent second rails 13 are consistent.
[0071] like Figure 1 As shown, the shelf 10 also includes a third track 14, which extends along the extension direction of the first track 12 and is located between adjacent second tracks 13. The third track 14 includes two third sub-tracks 140 parallel to each other (see Figure 8 ), each third sub-track 140 is arranged to be collinear with one first sub-track 120. The first track 12 and the third track 14 have the same extension direction, the third sub-track 140 and the first sub-track 120 are collinear, and the automatic guided vehicle 20 is arranged to be able to move along the first track 12, cross the second track 13 at the connection gap 133, and then move along the third track 14.
[0072] like Figure 8 As shown, the third sub-track 140 includes a third bearing surface 141 and a third limiting portion 142. The third bearing surface 141 is in a horizontal plane, and the first wheel 21 in the automatic guided vehicle 20 can be pressed on the third bearing surface 141, and the third bearing surface 141 is arranged to be in the same horizontal plane as the first bearing surface 121 to prevent the automatic guided vehicle 20 from bumping and colliding.
[0073] The third limiting portion 142 is located at the edge of the third bearing surface 141 and protrudes from the third bearing surface 142. The third limiting portion 142 can be used to limit the movement direction of the first wheel 21. The cross-sectional shape of the third sub-track 140 can be set to be substantially the same as the cross-sectional shape of the first sub-track 120 or the cross-sectional shape of the second sub-track 130. The position of the third limiting portion 142 relative to the third bearing portion 141 is preferably set to be the same as the position of the first limiting portion 122 relative to the first bearing portion 141, for example, both are located on the side away from each other in two mutually parallel first sub-tracks 120 of the same first track 12, that is, located on the outside of the first wheel 21 of the automatic guided vehicle 20.
[0074] In a preferred embodiment of the utility model, the first track 12, the second track 13 and the third track 14 can constitute a grid-shaped track that intersects each other in the same horizontal plane. The automatic guided vehicle 20 can change direction at the intersection of the first track 12 and the second track 13, for example, move along the direction of the first track 12, cross the second track 13, and continue to move along the third track 14; the automatic guided vehicle 20 can also move along the second track 13, and the specific movement route is selected according to the route planning.
[0075] According to a preferred embodiment of the present utility model, Figure 2 As shown, the first sub-rail 120 also includes a first skirt 123, which is arranged on the side of the extension direction of the first sub-rail 120. Preferably, the first bearing surface 121 and the first limiting portion 122 are bent downward and then bent outward to form the first skirt 123. The downward bent portions of the edges of the first bearing surface 121 and the first limiting portion 122 can be bent in a vertical direction or bent outwardly.
[0076] like Figure 4 As shown, the second sub-track 130 also includes a second skirt 134, which is arranged on the side of the extension direction of the second sub-track 130. For example, after the edge of the second bearing surface 131 is bent downward, it is bent outward again to form the second skirt 134. The second skirt 134 can also be arranged on both sides of the second sub-track 130, for example Figure 2 The first skirt 123 and the second skirt 134 are used for installation. For example, the first skirt 123 and the second skirt 134 are provided with threaded holes and can be installed on the column 11 or a structure connected to the column 11, which will be described in detail in the subsequent embodiments.
[0077] Preferably, the first skirt 123 is arranged on both sides of the extension direction of the first sub-rail 120, and the second skirt 134 is arranged on one side of the extension direction of the second sub-rail 130, preferably on the opposite side of two parallel second sub-rails 130 in the same second rail 13, so as to avoid other installation structures and further reduce the weight.
[0078] like Figure 7 and Figure 8As shown, the shelf 10 further includes a connecting plate 15, which is disposed below the first sub-rail 120 and / or the second sub-rail 130, and the first skirt 123 and the second skirt 134 are both fixedly connected to the connecting plate 15. In different embodiments of the utility model, the connecting plate 15 can be configured in a strip shape and disposed below the first sub-rail 120 and / or the second sub-rail 130 along the same direction as the first sub-rail 120 and / or the second sub-rail 130. In other embodiments of the utility model, the connecting plate 15 can also be disposed at the position where the first sub-rail 120 and the second sub-rail 130 intersect.
[0079] like Fig. 9 As shown, according to a preferred embodiment of the present invention, the connecting plate 15 can be configured as a U-shaped structure, which is beneficial to improving the compressive and bending strengths of the connecting plate 15. Both sides of the U-shaped structure can also be provided with outwardly turned skirts for fixedly connecting with the first skirt 123 and the second skirt 134.
[0080] Further, such as Figure 8 As shown, in a preferred embodiment of the utility model, the shelf 10 also includes a connecting member 16, which is fixedly connected to the column 11, for example, by welding or bolting, and the connecting member 16 is arranged along the extension direction of the second rail 13, and can withstand lateral loads, thereby improving the stability and load-bearing capacity of the shelf 10.
[0081] like Figure 8 As shown, the third track 14 is crimped onto the connecting member 16 and is fixedly connected to the connecting member 16. Specifically, the third sub-track 140 may be provided with a third skirt (not shown in the figure), which is provided on one side of the extension direction of the third sub-track 140, and the third skirt is located on the opposite side of two third sub-tracks 140 parallel to each other in the same third track 14. Figure 8 and Fig.10 As shown, the connecting member 16 is provided with a folded edge 161 on one side close to the bottom surface of the third rail 14 , and the third skirt can be fixedly connected to the folded edge 161 .
[0082] like Fig. 9 As shown, according to a preferred embodiment of the utility model, a gasket 151 is provided at the position where the connecting plate 15 and the first skirt 123 are connected. The gasket 151 can raise the height of the first sub-rail 120 and compensate for the thickness of the folded edge 161, so that the first bearing surface 121 and the third bearing surface 141 are in the same horizontal plane. At the same time, the structural dimensions of the first sub-rail 120 and the third sub-rail 140 are roughly the same, and can be manufactured using the same mold to reduce production costs.
[0083] like Figure 1As shown, in a preferred embodiment of the utility model, the shelf 10 further includes a support frame 17, the support frame 17 is fixedly connected to the connecting member 16, and the support frame 17 is arranged above the second track 13 and / or the third track 14.
