Description

Technical Field

[0001] The present invention relates to the field of smart logistics technology, and in particular to a supporting mechanism and a shuttle vehicle. Background Art

[0002] Currently, shuttle vehicles require guide plates on the vehicle body for guidance and support when loading and unloading cargo. The guide plates typically have mounting holes and screws for the relevant mounting parts, so cargo will rub against the edges of the holes or screw caps when loading and unloading. Because the guide plates are relatively thin and the mounting holes are countersunk, any slight deviation in the size of the mounting holes will cause the screw caps to protrude and not fully sink. Alternatively, vibration during use may loosen the screws, causing the screw caps to move upwards. This allows the card box or cargo to pass through, but plastic debris is ground down. Over time, the accumulated plastic debris will accumulate on the ground, affecting the working environment of the shuttle vehicle's access system, the normal transmission of the shuttle vehicle's access system, and damage to the cargo.

[0003] Therefore, it is urgent to design a new supporting mechanism and shuttle to improve the above problems. Summary of the Invention

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0055] The shuttle storage and retrieval system provided by the embodiment of the present disclosure includes shelves, shuttles, cargo reciprocating elevators, shuttle layer-changing elevators, etc. The cargo reciprocating elevators carry goods entering / out of the warehouse and connect with the shelves on each layer or with the conveyor line, and the shuttle layer-changing elevators carry shuttles to different layers of the shelves for operation.

[0056] The shuttle vehicle of the embodiment of the present disclosure is described by taking the cargo variable distance shuttle vehicle 100 as an example. Figure 1 and Figure 2 As shown, the variable-length cargo shuttle 100 provided in the embodiment of the present disclosure includes a first car body 20, a second car body 30 and a traveling mechanism 80. The first car body 20 and the second car body 30 are spaced apart in the front-to-rear direction. The first car body 20 and the second car body 30 are respectively provided with a traveling mechanism 80, wherein one group of traveling mechanisms 80 can be driving wheels, and the other group of traveling mechanisms 80 can be driven wheels. The driving wheels can drive the variable-length cargo shuttle 100 to move along the guide rails of the shelf, thereby realizing the movement of the variable-length cargo shuttle 100 to different positions on the shelf.

[0057] In addition, if Figure 1 and Figure 2As shown, the variable-length cargo shuttle 100 of the present embodiment also includes a fork 50. The fork 50 is provided on each of the first and second car bodies 20, 30. The fork 50 includes a fixing mechanism 51 and a fork-exit mechanism 52. The fixing mechanism 51 is fixedly connected to the corresponding first and second car bodies 20, 30, and the fork-exit mechanism 52 can extend or extend into the first and second car bodies 20, 30, thereby enabling the transfer of cargo 200 between the variable-length cargo shuttle 100 and the shelf. The cargo 200 can be original box cargo, such as a box of printing paper, a box of toys, a box of computers, etc. In addition, the cargo 200 can also include a material box and the actual products placed therein. The material box can be a cargo frame, a load-bearing box, etc., and the actual products to be transported can be placed in the material box. Among them, the material box can also be used as a special type of cargo 200 to be transported by the variable-length cargo shuttle 100.

[0058] like Figure 1 and Figure 2 As shown, the variable-distance cargo shuttle 100 of the disclosed embodiment further includes a supporting mechanism 10. The first vehicle body 20 and the second vehicle body 30 are respectively provided with a corresponding supporting mechanism 10. The two supporting mechanisms 10 are located between the first vehicle body 20 and the second vehicle body 30. Each supporting mechanism 10 is fixedly connected to the corresponding first vehicle body 20 or the second vehicle body 30. The two supporting mechanisms 10 are spaced apart in the front-to-back direction, and the two supporting mechanisms 10 are used to support different sides of the cargo 200. The two supporting mechanisms 10 can provide stable support for the cargo 200.

[0059] In addition, the variable-distance cargo shuttle 100 of the disclosed embodiment further includes a drive mechanism (not shown) for driving the two supporting mechanisms 10 toward or away from each other, thereby achieving the variable distance function of the variable-distance cargo shuttle 100 and enabling the variable-distance cargo shuttle 100 to carry cargo 200 of different sizes. The drive mechanism of the disclosed embodiment can drive the support mechanism 10 on only one side or simultaneously drive the support mechanisms 10 on both sides. The specific structure of the drive mechanism is relatively common in the art and will not be described in detail in the disclosed embodiment.

[0060] like Figure 1 and Figure 2 As shown, the forks 50 include a movable fork (located at the front) and a fixed fork (located at the rear), that is, the driving mechanism can drive the movable fork to move so that the movable fork and the fixed fork move closer to or farther away from each other. In an optional embodiment, both forks 50 can also be movable forks, that is, both forks can move, thereby achieving the two movable forks moving closer to or farther away from each other.

[0061] In addition, if Figure 1 and Figure 2As shown, the cargo variable-distance shuttle 100 also includes a guide shaft 40, which extends in the front-to-rear direction. The guide shaft 40 is arranged between the first car body 20 and the second car body 30. The supporting mechanism 10 includes a supporting member 11 and a bushing 13 arranged on the supporting member 11. The bushing 13 is sleeved on the outer periphery of the guide shaft 40. The guide shaft 40 cooperates with the bushing 13 to achieve a stable support effect on the supporting mechanism 10.

[0062] Specifically, if Figure 1 and Figure 2 As shown, the supporting member 11 includes a support plate 111 and a guide plate 112 fixedly connected to and perpendicular to the support plate 111, and the support plate 111 and the guide plate 112 both extend in the left-right direction, wherein the support plate 111 is used to better support the goods 200, and the guide plate 112 can guide the goods 200 in and out of the goods variable-distance shuttle 100 in the left-right direction, thereby achieving more accurate transmission of the goods 200 between the shelf and the goods variable-distance shuttle 100, avoiding the deflection of the goods 200 during the transmission process, avoiding the problem of the goods 200 being stuck during the transmission process, ensuring the smooth transmission of the goods 200, and ensuring the good quality of the goods 200 and the goods therein.

[0063] In addition, if Figure 1 and Figure 2 As shown, according to the different types of forks 50 provided on them, the bushing 13 is divided into a sliding bushing and a fixed bushing, wherein the sliding bushing is provided on the mobile fork, and the sliding bushing cooperates with the guide shaft 40. In addition to supporting the mobile fork, the sliding bushing can also achieve a better guiding effect on the movement of the mobile fork, thereby preventing the mobile fork from deflecting during the movement.

[0064] like Figure 1 and Figure 2 As shown, the sliding bushings can be provided in at least two groups, with the at least two groups of sliding bushings spaced apart along the extension and retraction direction of the fork mechanism 52. The guiding effect of the at least two groups of sliding bushings can further enhance the guiding effect of the moving fork, preventing the moving fork from getting stuck with the guide shaft 40 during movement, and ensuring smoother pitch switching of the cargo pitch shuttle 100. Furthermore, it can also prevent the moving fork from getting stuck due to rotation of the moving fork relative to the guide shaft 40. Furthermore, the at least two groups of sliding bushings cooperate with the guide shaft 40 to provide stable support for the moving fork, ensuring that the moving fork provides stable support for the cargo 200.

[0065] like Figure 1 and Figure 2As shown, a fixed bushing is provided on the fixed fork, and the fixed bushing cooperates with the guide shaft 40 to support the entire fixed fork and the supporting mechanism 10 on the fixed fork, wherein the material of the fixed bushing is a non-metallic material with a large friction coefficient. For example, the material of the fixed bushing can be nylon, engineering plastics, etc. The fixed bushing of the above materials can also play a certain buffering and anti-wear role.

[0066] like Figure 1 and Figure 2 As shown, the supporting mechanism 10 further includes a cargo detection component 14, which is used to detect the status of the cargo 200. The setting of the cargo detection component 14 can achieve a better transmission effect of the cargo 200 between the cargo variable-distance shuttle 100 and the shelf.

[0067] like Figure 1 As shown, the conventional variable-distance cargo shuttle 100 further includes fixing screws 90, wherein the bushing 13 is fixedly connected to the support plate 111 via the fixing screws 90, and the cargo detection assembly 14 is fixedly connected to the guide plate 112 via the fixing screws 90. The support plate 111 and the guide plate 112 are provided with mounting holes, and the fixing screws 90 can pass through the corresponding mounting holes to secure the bushing 13 to the support plate 111 and the cargo detection assembly 14 to the guide plate 112. Since the support plate 111 and the guide plate 112 are relatively thin, and the mounting holes are countersunk holes, if the size of the countersunk holes is slightly deviated, the ends of the fixing screws 90 will be exposed and cannot be completely sunk, or the fixing screws 90 may be loosened due to vibration during use of the cargo variable-distance shuttle 100, causing the fixing screws 90 to move upward. Therefore, when the cargo 200 enters and exits the cargo variable-distance shuttle 100, the cargo 200 will rub against the edges of the mounting holes or the ends of the fixing screws 90, causing the cargo 200 to be stuck during transportation, or although the cargo 200 can pass through, plastic debris will be ground off. The accumulated debris for a long time will accumulate on the ground or in the active position of the mechanical structure, affecting the working environment of the shuttle storage and retrieval system; affecting the normal transportation of the shuttle storage and retrieval system; and causing damage to the cargo 200.

[0068] To solve the above problems, Figure 2As shown, the supporting mechanism 10 of the embodiment of the present invention also includes a mounting assembly 12, which is fixedly connected to the supporting member 11, and the bushing 13 and the cargo detection assembly 14 are both fixedly connected to the mounting assembly 12, and the mounting holes opened on the support plate 111 and the guide plate 112 and the set fixing screws 90 are eliminated, thereby avoiding the problem of the mounting holes and fixing screws 90 in the prior art scratching the cargo 200. The surfaces of the support plate 111 and the guide plate 112 are smooth enough to prevent the support plate 111 and the guide plate 112 from jamming the cargo 200, and also avoid the wear of the support plate 111 and the guide plate 112 on the cargo 200. Therefore, it can ensure that the cargo 200 is smoothly transferred between the cargo variable-distance shuttle 100 and the shelf, and can also avoid damage to the cargo 200, and can ensure a better working environment of the shuttle access system and better transmission efficiency for the cargo 200.

[0069] In an optional embodiment, if Figure 2 As shown, the support member 11 and the mounting assembly 12 are an integrated structure, resulting in a simple structure for the support mechanism 10, a small footprint, and ease of fabrication. Specifically, the support member 11 and the mounting assembly 12 can be formed from sheet materials through a bending process, enabling rapid fabrication of the support member 11 and the mounting assembly 12, and enabling rapid assembly of the integrated support member 11 and the mounting assembly 12 with other structures. Furthermore, the integrated support member 11 and the mounting assembly 12 are relatively lightweight, enabling a lightweight design for the support mechanism 10 and the variable-distance cargo shuttle 100.

[0070] In an optional embodiment, the supporting member 11 and the mounting assembly 12 are formed by bending and welding steel plates, and can be formed by coordinating plate bending and welding processes, so as to realize a more diversified design of the integrated supporting member 11 and the mounting assembly 12, so that the integrated supporting member 11 and the mounting assembly 12 can be adapted to different models of cargo variable-distance shuttle vehicles 100.

[0071] In an optional embodiment, if Figures 2 to 5 As shown, the mounting assembly 12 includes a first mounting plate 121 perpendicular to the support plate 111 , and the bushing 13 is fixedly connected to the first mounting plate 121 . The first mounting plate 121 can achieve a stable supporting effect on the bushing 13 .

[0072] In an optional embodiment, if Figures 2 to 5 As shown, the first mounting plate 121 is located below the support plate 111, and the bushing 13 can be arranged below the support plate 111, which can avoid interference of the bushing 13 with the cargo 200. It can also achieve a compact arrangement of the bushing 13 and the supporting member 11 in the limited space of the cargo variable-distance shuttle 100, thereby ensuring a highly compact integrated setting of the cargo variable-distance shuttle 100 and achieving a smaller volume of the cargo variable-distance shuttle 100.

[0073] In an optional embodiment, if Figure 7 As shown, the cargo detection assembly 14 includes a first cargo detection mechanism 141 for detecting whether cargo 200 is placed on the support member 11. The first cargo detection mechanism 141 is fixedly connected to the first mounting plate 121, which provides a stable support for the first cargo detection mechanism 141. Furthermore, the first cargo detection mechanism 141 and the bushing 13 are both mounted on the first mounting plate 121, achieving a high degree of integration among the first cargo detection mechanism 141, the bushing 13, and the first mounting plate 121. This allows for a compact arrangement of the first cargo detection mechanism 141, the bushing 13, and the support member 11 within the limited space of the variable-distance cargo shuttle 100, ensuring a highly compact, integrated configuration of the variable-distance cargo shuttle 100 and minimizing the size of the variable-distance cargo shuttle 100.

[0074] In an optional embodiment, if Figure 7 As shown, the first cargo detecting mechanism 141 can be arranged below the support plate 111 , which can prevent the bushing 13 from interfering with the cargo 200 .

[0075] For example, Figure 7 As shown, the first cargo detection mechanism 141 can be a laser detection mechanism, etc., any type of detection mechanism that can determine whether cargo 200 is placed on the support member 11 is within the scope of protection of the present disclosure. In particular, the laser detection mechanism emits light obliquely upward, which can accurately determine whether cargo 200 is placed on the support member 11.

[0076] In an optional embodiment, if Figure 7 As shown, at least two first cargo detection mechanisms 141 are provided on each first mounting plate 121. The at least two first cargo detection mechanisms 141 are spaced apart in the left-right direction, which can avoid missed detection of the cargo 200 on the support plate 111 and improve the accurate detection of whether there is cargo 200 on the support plate 111.

[0077] In an optional embodiment, if Figures 4 to 6 As shown, when the bushing 13 is a sliding bushing, the length of the bushing 13 along its axis is relatively large, the size of the bushing 13 and the guide shaft 40 is relatively large, and the guide shaft 40 can achieve a better guiding effect for the bushing 13. Exemplarily, the size of the bushing 13 along the front-to-back direction is L1, and the size of the guide shaft 40 along the front-to-back direction is L2, wherein L1 / L2 is 1 / 5 to 1 / 20, and exemplary, L1 / L2 can be 1 / 5, 1 / 6, 1 / 7, 1 / 8, 1 / 9, 1 / 10, 1 / 11, 1 / 12, 1 / 13, 1 / 14, 1 / 15, 1 / 16, 1 / 17, 1 / 18, 1 / 19, 1 / 20, etc.

[0078] In an optional embodiment, if Figures 4 to 6 As shown, two first mounting plates 121 are provided, and the two first mounting plates 121 are spaced apart along the front-to-back direction to form an accommodating space 122, and the bushing 13 is provided in the accommodating space 122, and one end of the bushing 13 is fixedly connected to one of the first mounting plates 121, and the other end of the bushing 13 is fixedly connected to the other first mounting plate 121. The two first mounting plates 121 can jointly support and fix the bushing 13 that is longer along the front-to-back direction, so as to achieve a stable connection between the first mounting plate 121 and the bushing 13, thereby preventing the bushing 13 from loosening during the use of the cargo variable-distance shuttle 100, and a guide through hole 1311 extending along the front-to-back direction is provided on the bushing 13, so as to prevent the axis of the guide through hole 1311 from being deflected, and to prevent the axis of the guide through hole 1311 from forming an angle with the extending direction of the guide shaft 40, thereby preventing the bushing 13 and the guide shaft 40 from being stuck, and preventing the moving fork from being difficult to slide when changing the distance, thereby ensuring a smooth distance change effect of the cargo variable-distance shuttle 100.

[0079] like Figure 5 As shown, the first fixing members 15 on each first mounting plate 121 are arranged at equal intervals along the circumference of the guide hole 1311. This ensures that the bushing 13 is subjected to uniform force at all circumferential positions, ensuring that the axis of the guide hole 1311 does not deflect and that the axis of the guide hole 1311 coincides with the extension direction of the guide shaft 40. Furthermore, the presence of at least two first fixing members 15 on each side ensures a secure connection between the bushing 13 and the first mounting plate 121. For example, the number of first fixing members 15 on each first mounting plate 121 can be two, three, four, five, or more.

[0080] In addition, in the prior art, the fixing screw 90 is installed using a countersunk hole installation method. The fixing screw 90 cooperates with the countersunk hole, and the fixing screw 90 does not have any adjustment amount. Once the countersunk hole spacing is out of tolerance, the fixing screw 90 will be installed, causing the axis of the guide through hole 1311 to be set at an angle to the extension direction of the guide shaft 40 or the two to be skewed, resulting in a radial force between the bushing 13 and the guide shaft 40. When the cargo distance shuttle 100 changes distance, the bushing 13 is easily stuck with the guide shaft 40, and it is difficult for the moving fork side to slide.

[0081] In order to solve the above problems, Figure 6As shown, as an optional solution, the support mechanism 10 further includes a first fixing member 15, which includes a first head portion 151 and a first rod portion 152 connected to each other. A first through-hole b1212 is defined in the mounting assembly 12, through which the first rod portion 152 passes and is fixedly connected to the bushing 13. The diameter D1 of the first through-hole b1212 is larger than the diameter D2 of the cross section of the first rod portion 152. The diameter D1 of the first through-hole b1212 is slightly larger to maintain a certain gap (installation adjustment) between the first through-hole b1212 and the first rod portion 152. This gap corrects the misalignment between the axis of the guide through-hole 1311 and the extension direction of the guide shaft 40, thereby preventing radial forces caused by the misalignment between the axis of the guide through-hole 1311 and the extension direction of the guide shaft 40. This effectively prevents the bushing 13 and the guide shaft 40 from getting stuck when the cargo shuttle 100 is changing distance, ensuring smooth sliding of the moving fork.

[0082] In an optional embodiment, a thread is provided on the first rod portion 152 , and the thread is screwed into the bushing 13 , thereby achieving a stable connection between the first rod portion 152 and the bushing 13 and preventing the first rod portion 152 and the bushing 13 from loosening and separating.

[0083] For example, the difference between D1 and D2 is 2 mm to 10 mm, so that the single-side adjustment amount of the first fixing member 15 is 1 mm to 5 mm, which can achieve a good calibration effect on the installation position of the bushing 13. For example, the difference between D1 and D2 can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.

[0084] In an optional embodiment, if Figure 6 As shown, the first fixing member 15 passes through the first mounting plate 121 and the bushing 13 from the outside to the inside in a direction perpendicular to the first mounting plate 121, so that the operator can fix the bushing 13 to the first mounting plate 121 from the outside of the first mounting plate 121, and the operator can quickly install the bushing 13 to the first mounting plate 121.

[0085] In an optional embodiment, if Figure 6 As shown, the supporting mechanism 10 further includes a first gasket 16, which is disposed between the first head 151 and the first mounting plate 121. The first gasket 16 can increase the friction between the first fixing member 15 and the first mounting plate 121, thereby more firmly adhering the first fixing member 15 and the first mounting plate 121. This increased friction can prevent the first fixing member 15 from loosening due to vibration or other external forces, thereby improving the stability and reliability of the connection.

[0086] In an optional embodiment, if Figures 4 to 6As shown, the variable distance cargo shuttle 100 further includes a connector 60, through which the cargo fork 50 and the mounting assembly 12 of the corresponding supporting mechanism 10 are fixedly connected, enabling the cargo fork 50 and the corresponding supporting mechanism 10 to move synchronously. Figures 4 to 6 As shown, the connecting member 60 can be a connecting rod, and the variable-length cargo shuttle 100 also includes a second fixing member 70. The cargo fork 50 and the mounting assembly 12 are respectively fixedly connected to the connecting rod via the second fixing member 70. The matching structure of the connecting member 60 and the second fixing member 70 is simple, small in size, and light in weight. By matching the connecting member 60 and the second fixing member 70, the cargo fork 50 and the supporting mechanism 10 can be quickly installed. Exemplarily, the second fixing member 70 can be a screw, a pin, etc. In an optional embodiment, the material of the connecting member 60 can be selected from steel, aluminum alloy, titanium alloy, magnesium alloy, carbon fiber, stainless steel, etc., which can ensure high strength and hardness of the connecting member 60 and achieve a stable connection between the cargo fork 50 and the supporting mechanism 10.

[0087] In an optional embodiment, if Figures 4 to 6 As shown, the second fixing member 70 includes a second head portion 71 and a second rod portion 72 connected to each other. The mounting assembly 12 defines a second through-hole 1213, through which the second rod portion 72 passes and is fixedly connected to the connector 60. The diameter D3 of the second through-hole 1213 is larger than the diameter D4 of the cross section of the second rod portion 72. The slightly larger diameter D3 of the second through-hole 1213 maintains a certain clearance (installation adjustment) between the second through-hole 1213 and the second rod portion 72. This clearance corrects the relative position of the support mechanism 10 and the connector 60 after assembly, avoiding misalignment between the axis of the guide through-hole 1311 and the extension direction of the guide shaft 40 due to installation errors. This prevents radial forces caused by the misalignment between the axis of the guide through-hole 1311 and the extension direction of the guide shaft 40. This effectively prevents the bushing 13 from becoming stuck with the guide shaft 40 during pitch change of the cargo shuttle 100, ensuring smooth sliding of the moving fork.

[0088] In an optional embodiment, a thread is provided on the second rod portion 72 , and the thread is screwed into the connecting member 60 , thereby achieving a stable connection between the second rod portion 72 and the connecting member 60 and preventing the second rod portion 72 and the connecting member 60 from loosening and separating.

[0089] For example, the difference between D3 and D4 is 2 mm to 10 mm, so that the single-side adjustment amount of the second fixing member 70 is 1 mm to 5 mm, which can achieve a good calibration effect on the relative position of the supporting mechanism 10 and the connecting member 60 after assembly. For example, the difference between D1 and D2 can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.

[0090] In an optional embodiment, if Figure 6 As shown, the second fixing member 70 further includes a second gasket 73, which is disposed between the first head 151 and the first mounting plate 121. The second gasket 73 can increase the friction between the connecting member 60 and the first mounting plate 121, thereby more firmly adhering the second fixing member 70 to the first mounting plate 121. This increased friction can prevent the second fixing member 70 from loosening due to vibration or other external forces, thereby improving the stability and reliability of the connection.

[0091] In an optional embodiment, if Figures 7 and 8 As shown, a positioning hole 1211 is provided on the first mounting plate 121, and the bushing 13 includes a positioning column 131. The positioning column 131 is provided with a guide hole 1311 for passing the guide shaft 40. The positioning column 131 is inserted into the positioning hole 1211. Through the cooperation between the positioning column 131 and the positioning hole 1211, the position of the bushing 13 can be accurately positioned, so that the axis of the guide hole 1311 is consistent with the extension direction of the guide shaft 40, which can prevent the radial force caused by the inconsistency between the axis of the guide hole 1311 and the extension direction of the guide shaft 40. When the cargo distance-changing shuttle 100 changes distance, it can effectively avoid the bushing 13 and the guide shaft 40 from getting stuck, thereby ensuring the smooth sliding of the moving fork side.

[0092] In an optional embodiment, if Figures 7 and 8 As shown, the bushing 13 further includes a mounting flange 132, which is disposed on the positioning column 131. The mounting flange 132 is in surface contact with and fixedly connected to the first mounting plate 121. The provision of the mounting flange 132 enables a stable connection between the bushing 13 and the first mounting plate 121. The mounting flange 132 is fixedly connected to the first mounting plate 121 via the first fixing member 15. The provision of the mounting flange 132 facilitates the provision of more first fixing members 15, which enables a stable connection between the mounting flange 132 and the first mounting plate 121.

[0093] like Figure 8As shown, the mounting flange 132 defines a first through-hole a1321, through which the first rod portion 152 passes and is fixedly connected to the mounting assembly 12. The diameter D5 of the first through-hole a1321 is larger than the diameter D6 of the cross section of the first rod portion 152. The slightly larger diameter D5 of the first through-hole a1321 maintains a certain clearance (installation adjustment) between the first through-hole a1321 and the first rod portion 152. This clearance corrects the relative position of the support mechanism 10 and the connector 60 after assembly, thereby preventing misalignment between the axis of the guide through-hole 1311 and the extension direction of the guide shaft 40 caused by installation errors. This prevents radial forces caused by the misalignment between the axis of the guide through-hole 1311 and the extension direction of the guide shaft 40. This effectively prevents jamming between the bushing 13 and the guide shaft 40 during pitch change of the cargo shuttle 100, ensuring smooth sliding of the moving fork.

[0094] In an optional embodiment, a thread is provided on the first rod portion 152 , and the thread is screwed into the first mounting plate 121 , thereby achieving a stable connection between the first rod portion 152 and the first mounting plate 121 and preventing the first rod portion 152 from loosening and separating from the first mounting plate 121 .

[0095] For example, the difference between D5 and D6 is 2 mm to 10 mm, so that the single-side adjustment of the first fixing member 15 is 1 mm to 5 mm, which can achieve a good calibration effect on the relative position of the support mechanism 10 and the mounting assembly 12 after assembly. For example, the difference between D5 and D6 can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.

[0096] In an optional embodiment, if Figures 2 to 5 As shown, the cargo detection component 14 also includes a second cargo detection mechanism 142, and the fork mechanism 52 includes a fork plate surface 521. The second cargo detection mechanism 142 needs to transmit a signal in the left and right directions to the shelf. The transmitted signal needs to be flush with the fork plate surface 521. The second cargo detection mechanism 142 is used to detect whether the cargo 200 on the shelf is skewed, thereby avoiding the problem that the cargo variable-distance shuttle 100 cannot obtain the cargo 200 on the shelf.

[0097] In summary, the supporting mechanism 10 of the embodiment of the present disclosure integrates the bushing 13 and the first cargo detection mechanism 141 and the second cargo detection mechanism 142 with different functions on the supporting member 11. Through reasonable arrangement, the various components in the supporting mechanism 10 can be compactly arranged in a limited space, and the compact arrangement between the supporting mechanism 10 and the fork 50 can be ensured.

[0098] Exemplarily, the second cargo detection mechanism 142 may be a laser detection mechanism, etc. All detection mechanisms capable of determining whether there is cargo 200 on a shelf directly opposite it are within the scope of protection of the presently disclosed embodiments. The variable-length cargo shuttle 100 further includes a control mechanism electrically connected to the second cargo detection mechanism 142, the travel mechanism 80, the fork 50, and the drive mechanism. The control mechanism can control the travel mechanism 80, the fork 50, and the drive mechanism to perform corresponding operations based on the information detected by the second cargo detection mechanism 142, thereby preventing the fork 50 from colliding with the cargo 200 on the shelf and thus preventing the variable-length cargo shuttle 100 from being able to retrieve the cargo 200 on the shelf.

[0099] In order to avoid interference of other structures on the cargo variable distance shuttle 100 with the signal transmitted by the second cargo detection mechanism 142, the existing second cargo detection mechanism 142 is usually set at the top of the fork mechanism 52. However, this will lead to three serious problems: 1) the second cargo detection mechanism 142 moves with the fork mechanism 52, and the wires connected to the second cargo detection mechanism 142 will also move with the fork mechanism 52, which will cause the wires to break, disconnect, be squeezed, and other problems, affecting the normal transmission of the signal of the second cargo detection mechanism 142; 2) In order to avoid interference with other structures of the shuttle access system, the volume of the second cargo detection mechanism 142 is set to be smaller, resulting in lower accuracy of the detection results of the second cargo detection mechanism 142; 3) The setting of the second cargo detection mechanism 142 causes the overall height of the cargo variable-distance shuttle 100 to be larger, and the lower-level cargo variable-distance shuttle 100 is prone to interference with the upper-level cargo variable-distance shuttle 100, and the fork mechanism 52 is also prone to interference with the shelf, which will lead to the need to increase the height of a single layer of the shelf, affecting the shelf inventory rate. The inventory rate of shelves of the same volume is lower.

[0100] In order to solve the above problems, Figures 2 to 5As shown, the mounting assembly 12 includes a second mounting plate 123 connected to the guide plate 112. The second cargo detection mechanism 142 is disposed on the second mounting plate 123. The second cargo detection mechanism 142 and the support plate 111 are located on either side of the guide plate 112. First, the second cargo detection mechanism 142 is no longer located on the fork mechanism 52. The movement of the fork mechanism 52 does not affect the second cargo detection mechanism 142 or the wires, preventing the wires from breaking, disconnecting, or being squeezed. This ensures proper signal transmission from the second cargo detection mechanism 142. Furthermore, the second cargo detection mechanism 142 is relatively stable, minimizing vibration interference in signal transmission and detection, resulting in more accurate signal transmission and detection. Furthermore, since it is no longer located on the fork mechanism 52, the second cargo detection mechanism 142 does not need to be compact. A relatively larger second cargo detection mechanism 142 can be used, resulting in more accurate detection results.

[0101] In an optional embodiment, if Figure 3 As shown, the detection signal emitted by the second cargo detection mechanism 142 is parallel to the fork plate surface 521, the second cargo detection mechanism 142 is located between the supporting mechanism 10 and the fixing mechanism 51, and the second cargo detection mechanism 142 is located below the fork mechanism 52. The overall height of the cargo variable-distance shuttle 100 will not increase due to the setting of the second cargo detection mechanism 142, the lower-layer cargo variable-distance shuttle 100 will not interfere with the upper-layer cargo variable-distance shuttle 100, and the fork mechanism 52 will not interfere with the shelf. The height of a single layer of the shelf does not need to be increased, and shelves of the same volume can ensure a higher inventory rate.

[0102] In an optional embodiment, if Figure 3 As shown, the second cargo detection mechanism 142 is lower than the top of the guide plate 112. The guide plate 112 can completely isolate the second cargo detection mechanism 142 from the cargo 200, thereby preventing the cargo 200 from affecting the detection result of the second cargo detection mechanism 142. It can also prevent the second cargo detection mechanism 142 from interfering with the cargo 200 entering and exiting the cargo variable-distance shuttle 100, thereby ensuring that the cargo 200 enters and exits the cargo variable-distance shuttle 100 more smoothly and ensuring the good quality of the second cargo detection mechanism 142 and the cargo 200.
