[0041] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0042] like Figure 1 and Figure 2 As shown, the pallet arranging device provided in this embodiment includes a vehicle body 1 , a detection mechanism 2 and an operating mechanism 3 .

[0043] A vehicle body 1 is configured to navigate within a high-bay warehouse. A detection mechanism 2 is mounted on the vehicle body 1 and configured to identify the degree of deformation of a deformed pallet 100. An operating mechanism 3 includes a fork 31 and a fork drive assembly 32. The fork drive assembly 32 is mounted on the vehicle body 1 and is movably connected to the fork drive assembly 32. The fork drive assembly 32 is capable of driving the fork 31 to extend or retract relative to the vehicle body 1. The fork 31 is configured to transfer the deformed pallet 100.

[0044] In specific implementation, when a deformed pallet 100 is detected in the high-bay warehouse, the pallet sorting device is activated, causing the vehicle body 1 to move to the designated location where the deformed pallet 100 is located. The detection mechanism 2 then identifies the degree of deformation of the deformed pallet 100, allowing a sorting plan to be formulated based on the actual detection results. For example, the sorting plan may include determining the distance to which the fork 31 should be extended and whether the vehicle body 1 requires fine-tuning. Next, the operating mechanism 3 is activated, and the fork 31, driven by the fork drive assembly 32, extends relative to the vehicle body 1, allowing the fork 31 to pick up the deformed pallet 100 and place it on a normal pallet. A standard four-way shuttle then removes the deformed pallet 100 from the high-bay warehouse. Furthermore, the fork 31 remains retracted during the movement of the vehicle body 1, without affecting its movement.

[0045] The vehicle body 1 may be a conventional four-way shuttle vehicle or other simple small vehicles, which are not specifically limited here.

[0046] The pallet sorting device provided in this embodiment utilizes a vehicle body 1 to enable the entire device to move within a three-dimensional warehouse. A detection mechanism 2 and an operating mechanism 3 are provided on the vehicle body 1 to cooperate with each other. The detection mechanism 2 can identify the degree of deformation of a deformed pallet 100, thereby formulating a reasonable and more targeted sorting plan. The deformed pallet 100 is then transferred using the retractable fork 31 of the operating mechanism 3. This eliminates the need for manual entry into the warehouse, avoiding interruptions to warehouse operations caused by manual sorting, ensuring continuous operation, and reducing safety risks for personnel entering the warehouse. Furthermore, the pallet sorting device significantly shortens the time it takes to process deformed pallets 100, helping to increase production capacity.

[0047] like Figure 1 As shown, in some embodiments, a lifting mechanism 4 is further provided on the vehicle body 1, and the lifting mechanism 4 includes a vertical guide rod 41 and a lifting drive assembly 42. The vertical guide rod 41 is connected to the vehicle body 1, and the lifting drive assembly 42 is provided on the vertical guide rod 41. The fork 31 is connected to the lifting drive assembly 42, and the lifting drive assembly 42 is configured to drive the fork 31 to rise and fall along the vertical guide rod 41 after being extended relative to the vehicle body 1.

[0048] By setting up the lifting mechanism 4, the fork 31 can be lifted vertically, so that the fork 31 can be flexibly and accurately adjusted according to the actual shape and height of the deformed pallet 100, ensuring that the fork 31 can transfer the deformed pallet 100 more accurately and smoothly, which is conducive to improving the accuracy and efficiency of the sorting operation.

[0049] like Figure 1As shown, in some embodiments, the lifting drive assembly 42 includes a second motor 421, a suspension guide device 422 and a connecting member 423. The suspension guide device 422 is arranged at the end of the vertical guide rod 41 away from the connection with the vehicle body 1. The second motor 421 is connected to the vertical guide rod 41 and is spaced apart from the suspension guide device 422. One end of the connecting member 423 is connected to the second motor 421, and the other end of the connecting member 423 bypasses the suspension guide device 422 and is connected to the fork 31.

[0050] When the second motor 421 reels the connecting member 423, the fork 31 rises; when the second motor 421 releases the connecting member 423, the fork 31 descends. The provision of the suspension guide 422 stabilizes and controls the movement of the connecting member 423, ensuring smooth and precise raising and lowering of the fork 31. This arrangement effectively adjusts the height of the fork 31, allowing for smoother transfer of deformed pallets 100.

[0051] Alternatively, the connecting member 423 may be configured as a chain, and correspondingly, the suspension guide device 422 may be configured as a sprocket that cooperates with the chain. In other embodiments, the connecting member 423 may be configured as a strip, and correspondingly, the suspension guide device 422 may be configured as a fixed pulley. The specific configuration may be determined based on actual circumstances and is not specifically limited in this application.

[0052] like Figure 1 As shown, in some embodiments, the vertical guide rod 41 is rotatably connected to the vehicle body 1, a first motor 5 is provided on the vehicle body 1, and a connecting rod 6 is provided between the first motor 5 and the vertical guide rod 41, one end of the connecting rod 6 is rotatably connected to the first motor 5, and the other end of the connecting rod 6 is rotatably connected to the vertical guide rod 41, and the first motor 5 can drive the connecting rod 6 to rotate in a first direction and a second direction, and the first direction is opposite to the second direction; the rotation of the connecting rod 6 in the first direction can drive the vertical guide rod 41 to rotate in the first direction until the vertical guide rod 41 and the vehicle body 1 are parallel to each other, and the rotation of the connecting rod 6 in the second direction can drive the vertical guide rod 41 to rotate in the second direction until the length direction of the vertical guide rod 41 is consistent with the vertical direction.

[0053] by Figure 1 Take the direction in as an example to illustrate, at this time, the first direction is counterclockwise and the second direction is clockwise. Figure 1The length direction of the vertical guide rod 41 is consistent with the vertical direction, and the vertical guide rod 41 and the vehicle body 1 are approximately 90 degrees apart. The vertical guide rod 41 is in an open state relative to the vehicle body 1. At this time, when the first motor 5 drives the connecting rod 6 to rotate in the counterclockwise direction, the vertical guide rod 41 rotates in the counterclockwise direction synchronously until it is parallel to the vehicle body 1. That is, the vertical guide rod 41 is in a folded state relative to the vehicle body 1. When the vertical guide rod 41 needs to be switched from the folded state to the open state, the first motor 5 drives the connecting rod 6 to rotate in the clockwise direction, and the vertical guide rod 41 is pushed by the connecting rod 6 to gradually open.

[0054] Through such a setting, the vertical guide rod 41 can be flexibly opened or folded. When the vehicle body 1 moves in the high-bay warehouse, the vertical guide rod 41 can be in a folded state to reduce the impact on the movement of the vehicle body 1; when the vehicle body 1 stops and the fork 31 needs to be raised and lowered along the vertical guide rod 41, the vertical guide rod 41 is switched to the open state.

[0055] like Figure 1 As shown, in some embodiments, the fork drive assembly 32 includes a third motor 321 and a transmission gear 322. The transmission gear 322 is connected to the third motor 321. A rack 311 is provided on the end of the fork 31 facing the transmission gear 322. The rack 311 can mesh with the transmission gear 322 to extend or retract the fork 31 relative to the vehicle body 1. In other words, the third motor 321 drives the transmission gear 322 to rotate, and the transmission gear 322 then meshes with the rack 311 to achieve movement of the fork 31.

[0056] This rack-and-pinion drive system offers the advantages of simple structure and high transmission efficiency. It precisely controls the extension and retraction position of the forks 31, improving the accuracy of the forks 31 in manipulating deformed pallets 100. Furthermore, this design provides greater thrust, helping to handle pallets of varying weights and shapes, and enhancing the device's applicability and operational reliability.

[0057] Optionally, the rack 311 and the fork 31 can be integrated to facilitate processing and manufacturing.

[0058] Furthermore, in some embodiments, the number of the transmission gears 322 is set to be multiple, and the multiple transmission gears 322 are arranged at intervals along the moving direction of the fork 31.

[0059] The number of the transmission gears 322 is set to be multiple, and the multiple transmission gears 322 are distributed on the moving path of the fork 31, so that the force generated during the transmission process can be shared more evenly, which is conducive to improving the stability of the fork 31 when moving.

[0060] like Figure 2As shown, in some embodiments, the detection mechanism 2 includes an optical camera 21 and a thermal imager 22. Both the optical camera 21 and the thermal imager 22 are connected to the vehicle body 1 and are arranged in the extension direction of the fork 31. The extension direction of the fork 31 corresponds to the position of the deformed pallet 100.

[0061] With this configuration, the inspection mechanism 2, through its combination of the optical camera 21 and the thermal imager 22, can perform a more comprehensive inspection of the deformed pallet 100. The optical camera 21 captures images of the deformed pallet 100's appearance, identifying its shape and position, while the thermal imager 22 detects the temperature distribution of the deformed pallet 100, identifying potential structural defects or damaged areas. These two complementary inspection methods allow the device to more accurately assess the deformation and location of the deformed pallet 100, thereby formulating a more appropriate disposal plan.

[0062] In some other embodiments, depending on actual conditions, only the optical camera 21 may be retained and the thermal imager 22 may be eliminated.

[0063] The optical camera 21 can identify the shape and position of the deformed pallet 100 through image recognition technology. This image recognition technology can utilize established solutions in the prior art, such as OpenCV, and will not be further described here. Other components required for image recognition (such as a control system, such as a microcomputer) can be integrated or installed on the vehicle body 1, or the images captured by the optical camera 21 can be remotely transmitted to the control system, which is not limited here.

[0064] like Figure 2 As shown, in some embodiments, the detection mechanism 2 further includes a plurality of lighting lamps 23 , and the plurality of lighting lamps 23 are arranged at intervals on one side of the vehicle body 1 facing the extending direction of the fork 31 .

[0065] Through such a setting, multiple lighting lamps 23 can provide sufficient lighting conditions when the optical camera 21 and the thermal imager 22 are working, ensuring that the image and thermal imaging information of the deformed pallet 100 can be clearly captured under various lighting environments, which is conducive to improving imaging quality and reducing recognition errors caused by insufficient light.

[0066] like Figure 2 As shown, in some embodiments, a cleaning brush 7 is also connected to the bottom of the vehicle body 1.

[0067] The cleaning brush 7 at the bottom of the vehicle body 1 can clean the dust and debris on the track. By keeping the track clean, the risk of the vehicle body 1 being stuck or unstable due to dust accumulation on the track can be reduced, thereby ensuring the smooth movement of the pallet sorting device in the warehouse and improving the operating reliability and maintenance efficiency of the equipment.

[0068] This embodiment also provides a pallet arrangement system, including a terminal device and a pallet arrangement device, wherein the terminal device and the pallet arrangement device are in communication connection. The terminal device can be a mobile phone, a computer, etc., which is not specifically limited here.

[0069] For example, an application (APP) can be set up on a mobile phone to connect to the pallet sorting device, so that the user can remotely control the pallet sorting device on the mobile phone, such as remotely controlling the movement of the vehicle body 1, the extension of the fork 31, etc., and the image obtained by the detection mechanism 2 can also be transmitted to the mobile phone for user viewing.

[0070] Through such a setting, the terminal device can easily receive and display the operating status, test results and work progress of the pallet sorting device, enabling users to monitor and remotely manage the sorting process in real time, which is conducive to improving the intelligence level of the entire logistics and warehousing management.

[0071] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
