Description

Technical Field

[0001] This utility model relates to the field of stacker technology, and in particular to a material tray equidistant stacking mechanism. Background Technology

[0002] Material trays, commonly used in industrial production, warehousing, and logistics, are made of plastic, metal, or composite materials and have specific shapes and structures. They offer numerous benefits in protecting materials, sorting and organizing, adapting to automation, improving space utilization, and facilitating traceability management. They are widely used in manufacturing (electronics, automobile manufacturing, etc.), warehousing and logistics, food, and pharmaceutical industries. Equidistant stacking mechanisms are crucial in industrial production and logistics warehousing, as they optimize space utilization (increase storage density and facilitate aisle planning), aid material management and protection (facilitate identification and retrieval, and prevent material damage), meet the needs of automated production and logistics (adapt to automated equipment and improve production and logistics efficiency), and ensure quality control and standardization (guarantee product consistency and compliance with industry standards).

[0003] A pallet equidistant stacking mechanism generally consists of support and positioning components, clamping and fixing components, lifting components, horizontal moving components, detection and control components, etc. The pallet equidistant stacking mechanism supports the pallets with pin supports and positions them with positioning blocks (grooves). The pallets are clamped by the coordinated action of moving and fixed clamping components. The servo motor drives the ball screw to realize the vertical equidistant lifting and stacking of the pallets based on preset spacing parameters. During this process, the worm gear reducer ensures smoothness and safety, and the sensors for moving and lifting ensure accuracy. Finally, the control device automatically and cyclically completes the continuous equidistant stacking task according to the preset program and HMI setting parameters.

[0004] Existing pallet stacking mechanisms often fail to stack pallets properly, meaning they can only be laid flat, resulting in significant waste of storage space. With limited warehouse space, laying pallets flat drastically reduces storage capacity. For companies with large-scale production or storage needs, this necessitates continuously expanding warehouse space, increasing rental costs and land usage. Randomly placed pallets make it difficult to create an orderly layout, increasing the difficulty of finding and moving pallets, obstructing passageways, hindering the movement of personnel and equipment, and reducing overall space utilization efficiency. Therefore, a pallet stacking mechanism with equal spacing is proposed to address these issues. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1 to 3 This utility model provides an embodiment of a material tray equidistant stacking mechanism, including a lifting component base plate 16. The lifting component base plate 16 is an important basic component of the entire mechanism, providing a stable installation foundation for subsequent work and laying the foundation for the stable operation of the entire stacking mechanism.

The fixed clamping sensor 23 can accurately detect the position information of the fixed clamping component and provide a high-precision origin limit for the horizontal movement of the fixed clamping component, ensuring that the fixed clamping component can be accurately positioned every time it moves, thereby ensuring that the clamping action of the material tray is accurate and reliable and avoiding poor clamping effect due to position deviation.

[0032] A servo motor 13 is fixedly connected inside the lifting assembly base plate 16. The servo motor 13 serves as the power source for the horizontal movement of the moving clamp assembly. It has good power output performance and can stably drive the gear 11 to rotate, accurately control the horizontal movement speed and position of the moving clamp assembly, and provide sufficient power for the precise clamping of the material tray, making the clamping process more accurate and efficient. A linear guide rail 12 is fixedly connected inside the lifting assembly base plate 16. The linear guide rail 12 provides a smooth guide path for the horizontal movement of the moving clamp slider fixing block 9, so that the moving clamp slider fixing block 9 can move stably and smoothly when moving horizontally, ensuring that the horizontal movement of the moving clamp assembly will not be stuck or deviated, and ensuring the smoothness of the clamping action.

[0033] The top of the linear guide rail 12 is fixedly connected to a movable clamp slider fixing block 9. The movable clamp slider fixing block 9 plays the role of connecting and transmitting power, which can effectively transmit power to the movable clamp assembly, ensuring the smooth power transmission process and ensuring that the movable clamp assembly can move horizontally according to the predetermined requirements to complete the clamping operation of the material tray. The top of the lifting component base plate 16 is fixedly connected to multiple right movable clamp connecting blocks 8. The right movable clamp connecting blocks 8 are important structures for connecting the movable clamp assembly, ensuring a stable connection between the movable clamp assembly and the part, so that the movable clamp assembly can play a stable role during horizontal movement and clamping operations, without loosening or instability. A movable clamp sensor 24 is fixedly connected to the outside of one of the right movable clamp connecting blocks 8. The movable clamp sensor 24 adopts advanced sensing technology, which can quickly and accurately sense the horizontal position of the movable clamp assembly, providing precise position feedback for the horizontal movement of the movable clamp assembly, thereby ensuring the action accuracy of the movable clamp assembly and making the clamping action more accurate and reliable.

[0034] The top of the right moving clamp connecting block 8 is fixedly connected to the moving clamp short connecting block 17. The moving clamp short connecting block 17 plays the role of connection and transition, which can effectively connect different parts together, ensure the coordination of the actions between various structures, reduce the error caused by poor connection, and ensure the continuity of the overall action of the mechanism. The bottom of the moving clamp short connecting block 17 is fixedly connected to the moving clamp lifting sensor 22. The moving clamp lifting sensor 22 can monitor the position information of the moving clamp assembly in the vertical direction in real time, provide precise origin limit for the lifting action of the moving clamp assembly, ensure that the moving clamp assembly operates strictly according to the predetermined height and position during the lifting process, and ensure that the stacking operation of the material tray in the vertical direction is accurate.

[0035] The bottom of the movable clamping short connecting block 17 is fixedly connected to the fixed clamping connecting block 18. The fixed clamping connecting block 18 tightly connects the fixed clamping assembly and the movable clamping slider fixing block 9, ensuring the coordinated work between the fixed clamping assembly and the movable clamping slider fixing block 9, and ensuring that the two can work in a coordinated manner when clamping the material tray, thereby improving the clamping effect on the material tray. The inside of the lifting assembly base plate 16 is fixedly connected to the linear guide rail 7. The linear guide rail 7 provides precise guidance for the horizontal movement of the fixed clamping assembly, ensuring the straightness and accuracy of the fixed clamping assembly when moving horizontally, so that the fixed clamping assembly can move precisely to the predetermined position and achieve precise clamping of the material tray.

[0036] A servo motor 25 is fixedly connected to the top of the lifting assembly base plate 16. The servo motor 25 provides power for the lifting action of the moving clamp assembly. It can accurately adjust the output according to the control signal and drive the ball screw 26 to rotate stably. This allows the moving clamp assembly to perform lifting operations according to different stacking requirements, ensuring smooth stacking of the material tray at different heights. A worm gear reducer 15 is fixedly connected to the top of the lifting assembly base plate 16. The worm gear reducer 15 works in conjunction with the servo motor 25 and has a strong torque output and self-locking function. This prevents the moving clamp assembly from falling due to gravity during the lifting process, ensuring the safety of the material tray during the lifting process. At the same time, it can provide sufficient force to drive the material tray to lift and lower stably, ensuring the safety and stability of the stacking operation.

[0037] A linear guide rail 3 14 is fixedly connected to the outer side of the lifting assembly base plate 16. The linear guide rail 3 14 provides precise guidance for the lifting of the right moving clamp assembly 3, ensuring that the lifting movement of the right moving clamp assembly 3 in the vertical direction is accurate and stable, avoiding swaying or deviation, and ensuring the stacking accuracy of the material tray in the vertical direction. The right moving clamp assembly 3 is slidably connected to the outer side of the linear guide rail 3 14. The right moving clamp assembly 3 is one of the key parts for clamping and supporting the material tray. It can effectively clamp and support the material tray, ensuring the stability of the material tray during clamping and lifting, and ensuring the smooth progress of the stacking operation. Multiple pin supports 1 are slidably connected inside the right moving clamp assembly 3. The pin supports 1 provide initial support for the material tray, enabling the material tray to remain stable when initially placed, avoiding swaying or displacement of the material tray before the start of operation, and providing good initial conditions for subsequent clamping and stacking operations.

[0038] A right fixed clamp assembly 2 is slidably connected to one side of the pin support 1. The right fixed clamp assembly 2 is an important part for clamping and supporting the material tray. It can effectively clamp the material tray and ensure that the material tray is subjected to a stable clamping force on one side in the horizontal direction, thus ensuring the stability of the material tray in the horizontal direction. A left fixed clamp assembly 4 is slidably connected to the side of the pin support 1 away from the right fixed clamp assembly 2. The left fixed clamp assembly 4 is symmetrically arranged with the right fixed clamp assembly 2. The two work together to apply a clamping force to the material tray from both sides, ensuring that the material tray is subjected to uniform force in the horizontal direction, improving the stability and reliability of clamping, and preventing the material tray from deforming or displacing due to uneven force.

[0039] On the other side of the pin support 1, a left moving clamp assembly 5 is slidably connected. The left moving clamp assembly 5 and the right moving clamp assembly 3 cooperate with each other to complete the horizontal clamping action of the material tray, ensuring that the material tray is firmly and stably clamped in the horizontal direction, providing a guarantee for subsequent lifting and stacking operations. The top of the lifting assembly base plate 16 is rotatably connected to a driving assembly for driving the parts.

[0040] The drive assembly includes gear 11, the bottom of which is rotatably connected to the top of the lifting assembly base plate 16. Gear 11 is a key structure that transmits the power of the servo motor 13 to the moving clamp assembly. It can stably transmit power to the moving clamp assembly, ensuring that the horizontal movement of the moving clamp assembly is sufficiently and stably powered, so that the moving clamp assembly can accurately perform horizontal clamping operations. Two racks 10 are slidably connected to the top of the lifting assembly base plate 16. The racks 10 mesh with gear 11, converting the rotational motion of gear 11 into linear motion, providing stable power transmission for the horizontal movement of the moving clamp assembly, and ensuring that the moving clamp assembly moves horizontally along a predetermined trajectory. The outer side of gear 11 is meshed with the outer side of rack 10.

[0041] Reference Figure 1 , Figure 2 , Figure 4 The drive assembly includes a second gear 20, the bottom of which is rotatably connected to the top of the lifting assembly base plate 16. The second gear 20 is the power transmission component for the horizontal movement of the fixed clamping assembly, which can effectively transmit power to the fixed clamping assembly, ensuring that the fixed clamping assembly moves horizontally at a predetermined speed and position to complete the clamping operation of the material tray. The lifting assembly base plate 16 is fixedly connected to a second linear guide rail 12, and the lifting assembly top plate 6 is slidably connected to the outside of the second linear guide rail 12. The lifting assembly top plate 6 provides top support and protection for the lifting assembly, ensuring the integrity and stability of the lifting assembly during operation, helping to improve the structural strength of the entire mechanism, and making the entire stacking mechanism more stable.

[0042] A servo motor 21 is fixedly connected to the top of the lifting assembly base plate 16. The servo motor 21 provides power for the horizontal movement of the clamping assembly and can precisely control the horizontal movement of the clamping assembly, so that the clamping assembly can accurately clamp the material tray in the horizontal direction, ensuring the accuracy and reliability of the clamping action. Two racks 29 are slidably connected to the top of the lifting assembly base plate 16. The racks 29 mesh with gears 20, converting the rotational motion of gears 20 into linear motion, providing precise power transmission and position control for the horizontal movement of the clamping assembly, ensuring that the clamping action of the clamping assembly in the horizontal direction is accurate.

[0043] The outer side of gear 20 is meshed with the outer side of rack 2 19. A ball screw 26 is fixedly connected inside the base plate 16 of the lifting assembly. The ball screw 26 is a key structure that converts rotary motion into linear motion. It can efficiently convert the rotary motion of servo motor 3 25 into the vertical linear motion of the moving clamp assembly, realize the precise lifting of the material tray in the vertical direction, and ensure the accuracy of the material tray's vertical position and the accuracy of the stacking operation during the stacking process.

[0044] Working Principle: When workers need to stack material trays, the trays can be supported by pins 1. Servo motor 13 is then activated as the power source, driving gear 11 to rotate. Gear 11 meshes with rack 10, which in turn drives the connected movable clamp slider fixing block 9. Through the right movable clamp connecting block 8, the right movable clamp assembly 3 and the symmetrically arranged left movable clamp assembly 5 move horizontally along linear guide rail 12, achieving the clamping action on the material trays. Linear guide rail 12 ensures the smoothness and accuracy of the horizontal movement of the movable clamp assembly. Meanwhile, servo motor 21 rotates, driving gear 20 to rotate. Rack 19, which meshes with gear 20, drives the fixed clamp assembly. Through the fixed clamp connecting block 18 and the movable clamp slider fixing block 9, the assembly moves horizontally along linear guide rail 17. The horizontal movement, in coordination with the moving clamp assembly, firmly clamps the material tray from both sides. The fixed clamp sensor 23 and the moving clamp sensor 24 provide origin limits for the horizontal movement of the fixed clamp assembly and the moving clamp assembly, respectively, ensuring the accuracy of each clamping position. The worm gear reducer 15 in the lifting assembly works in coordination with the servo motor 25. The servo motor 25 provides power and converts the rotational motion into the up and down movement of the moving clamp assembly along the linear guide rail 14 through the ball screw 26. The worm gear reducer 15 has a self-locking function to prevent the moving clamp assembly from falling due to gravity during the lifting process, while providing a large output torque to ensure that the moving clamp assembly can stably drive the material tray to rise or fall. The moving clamp lifting sensor 22 provides origin limits for the rising and falling of the moving clamp assembly, ensuring the vertical movement accuracy of the moving clamp assembly.
