[0027] Please refer to Figure 1 , Figure 2 and Figure 3This embodiment provides a pallet positioning and guiding mechanism 100 for use with a workstation. It includes at least one set of guiding mechanisms located at the edge of the workstation. Each set of guiding mechanisms includes two roller guiding assemblies 110 that are arranged opposite to each other and located at the edge of the workstation. The roller guiding assemblies 110 are used to guide the pallet 200 into the workstation through the wheel surface.
[0028] Specifically, each guiding mechanism consists of two opposing and precisely positioned roller guide assemblies 110 at the edge of the workstation. The roller guide assemblies 110 contact the pallet 200, skillfully guiding it into the workstation and achieving precise positioning. When using the pallet positioning and guiding mechanism 100 of this application to place the pallet 200, the pallet 200 is slowly driven towards the entrance of the pallet positioning and guiding mechanism 100. As the front end of the pallet 200 approaches the guiding mechanism, the two side edges of the pallet 200 gradually approach the corresponding roller guide assembly 110. Due to the rolling characteristics of the rollers, the edges of the pallet 200 gently contact the roller surfaces. Guided by the rollers, the pallet 200 automatically adjusts its position; even if the initial position of the pallet 200 is deviated, it can be corrected by the rollers. As the pallet 200 falls into the workstation due to its own weight, the rollers will continuously provide lateral constraints and guidance to ensure that the pallet 200 enters the workstation accurately along the correct path until the pallet 200 is completely placed on the workstation. At this time, the pallet 200 is precisely aligned and meets the warehouse planning requirements.
[0029] The pallet positioning and guiding mechanism 100 provided in this application is used in conjunction with a workstation. It includes at least one set of guiding mechanisms located at the edge of the workstation. Each set of guiding mechanisms includes two opposing roller guide assemblies 110 located at the edge of the workstation. The roller guide assemblies 110 guide the pallet 200 into the workstation via their wheel surfaces. Through the uniquely designed roller guide assemblies 110, the pallet 200 can achieve high-precision positioning during storage, ensuring that the deviation in the pallet 200's position is controlled within a minimal range each time. Furthermore, the precisely positioned pallet 200 allows for more stable stacking of goods. Compared to positioning methods using complex structures such as cylinders, guiding the pallet 200 into the workstation via the wheel surfaces of the roller guide assemblies 110 is simpler in structure, reducing the number of parts and cost. Simultaneously, the roller rolling guidance method effectively improves the efficiency of the pallet 200 entering the workstation.
[0030] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the roller guide assembly 110 includes a mounting base 111 located at the edge of the workstation and a plurality of roller assemblies 112 disposed on the mounting base 111, and the roller assemblies 112 guide the tray 200 into the workstation through the wheel surface of the guide tray 200.
[0031] Specifically, when the pallet 200 approaches the workstation, it first contacts the roller assembly 112 on the mounting base 111. The rolling surfaces of the roller assembly 112 provide guiding force to the pallet 200, allowing it to enter the workstation along a predetermined path. The arrangement of multiple roller assemblies 112 in this application increases the stability and accuracy of the guidance, better adapts to pallets 200 of different sizes and shapes, and improves the versatility of the guiding mechanism.
[0032] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the mounting base 111 is provided with a tray slot 1111, which holds the tray 200. The roller assembly 112 is located on the side of the mounting base 111 facing the tray slot 1111.
[0033] Specifically, when the pallet 200 is placed into the pallet positioning guide mechanism 100 of this application, the operator pushes the pallet 200 towards the mounting base 111. When the pallet 200 approaches the slot, the roller assembly 112 begins to guide the pallet 200 accurately into the slot, which holds the pallet 200 in place, ensuring its stable position. The pallet slots 1111 of the mounting bases 111 of the two opposing roller guide assemblies 110 form the installation space for the pallet 200.
[0034] The pallet slot 1111 enhances the positioning accuracy and stability of the pallet 200, preventing displacement of the pallet 200 at the workstation and ensuring the safety of goods storage and handling. The roller assembly 112 guides the pallet 200.
[0035] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the tray slot 1111 has at least two tray corners 1112, and a roller assembly 112 is provided on both sides of each tray corner 1112.
[0036] Specifically, when the pallet 200 is placed into the pallet positioning guide mechanism 100 of this application, when the pallet 200 approaches the pallet slot 1111, the roller assemblies 112 on both sides of the slot simultaneously contact the edge of the pallet 200, guiding the pallet 200 accurately into the slot from different directions, so that the pallet 200 can be accurately positioned in all directions.
[0037] The multiple corner brackets and roller assemblies 112 further improve the positioning accuracy and stability of the pallet 200, especially suitable for large or irregularly shaped pallets 200, ensuring that the pallet 200 is placed more firmly and accurately at the workstation.
[0038] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the roller assembly 112 includes a first roller 1121 and a second roller 1122 rotatably mounted on the mounting base 111. The first roller 1121 and the second roller 1122 are arranged sequentially along the direction in which the pallet 200 enters the work station.
[0039] During the process of pallet 200 entering the workstation, pallet 200 first contacts the first roller 1121, which begins to roll and guides pallet 200 to initially adjust its direction. As pallet 200 advances, the second roller 1122 then contacts the pallet 200, further guiding it to accurately enter the workstation. The sequential arrangement of the first roller 1121 and the second roller 1122 enables step-by-step guidance of pallet 200, improving the accuracy and flexibility of guidance and better handling various situations when pallet 200 enters the workstation.
[0040] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the mounting base 111 is also provided with a roller mounting groove 1113 that communicates with the tray slot 1111, and the first roller 1121 and the second roller 1122 are rotatably mounted in the roller mounting groove 1113.
[0041] Specifically, the roller mounting slot 1113 provides a stable mounting position for the first roller 1121 and the second roller 1122. When the pallet 200 enters the workstation, the rollers rotate smoothly in the mounting slot, guiding the pallet 200 through the slot into the workstation.
[0042] The roller mounting groove 1113 ensures the installation stability and rotational flexibility of the roller, enabling the roller to better perform its guiding function, and also facilitates the maintenance and replacement of the roller.
[0043] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, a sliding groove 1114 is provided on the side wall of the roller mounting groove 1113, and a sliding seat 1115 is slidably mounted on the sliding groove 1114. The first roller 1121 is rotatably mounted on the sliding seat 1115.
[0044] When the pallet 200 contacts the first roller 1121, if there is a certain deviation in the position of the pallet 200, the first roller 1121 will slide in the slide groove 1114 through the sliding seat 1115 to automatically adjust its position to accommodate the entry of the pallet 200, ensuring that the pallet 200 can smoothly enter the work station.
[0045] The sliding seat 1115 and the slide groove 1114 enable the first roller 1121 to have a certain self-adaptive capability, which can better cope with the positional deviation when the pallet 200 enters, and improve the fault tolerance and adaptability of the guiding mechanism.
[0046] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, an elastic reset member 1116 is provided between the sliding seat 1115 and the roller mounting groove 1113.
[0047] Specifically, during the process of pallet 200 entering the workstation, if the first roller 1121 drives the sliding seat 1115 to slide within the slide groove 1114, the elastic reset member 1116 will be compressed or stretched. After pallet 200 passes through, the elastic force of the elastic reset member 1116 causes the sliding seat 1115 to return to its initial position, preparing for the next entry of pallet 200.
[0048] The elastic reset element 1116 ensures that the first roller 1121 can return to the appropriate position after each passage of the pallet 200, ensuring the continuous and stable operation of the guide mechanism and improving the reliability and service life of the mechanism.
[0049] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the diameter of the first roller 1121 is smaller than the diameter of the second roller 1122.
[0050] Specifically, when the pallet 200 enters the workstation, the smaller diameter first roller 1121 contacts the pallet 200 first, allowing for more flexible adjustment of the pallet 200's initial orientation. As the pallet 200 advances, the larger diameter second roller 1122 provides a more stable guiding force, ensuring that the pallet 200 accurately enters the workstation.
[0051] This application fully leverages the advantages of different rollers by combining them with different diameters, which not only improves the flexibility of guidance but also ensures the stability of guidance, further enhancing the positioning accuracy of the pallet 200.
[0052] This application also discloses a cargo loading device, including a carrier with a workstation, a pallet 200, and the pallet positioning and guiding mechanism 100 from the foregoing embodiments. This cargo loading device has the same structure and beneficial effects as the pallet positioning and guiding mechanism 100 from the foregoing embodiments. The structure and beneficial effects of the pallet positioning and guiding mechanism 100 have been described in detail in the foregoing embodiments and will not be repeated here.
[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
