Description

Technical Field

[0001] This invention relates to the field of automated conveying technology in beer production lines, and specifically to a self-stabilizing heavy-duty pallet conveying device. Background Technology

[0002] In automated conveyor systems of beer production lines, heavy-duty pallets are commonly used to handle loads such as beer bottle cases, filling containers, or finished beer stacks. Traditional conveyor systems mostly use rigid conveyor belts or chain-driven fixed chassis structures, but these are prone to the following problems when operating at high speeds or under uneven loads:

[0003] Insufficient stability: Because beer production lines need to be started and stopped frequently or run at different speeds, inertia can easily cause the bottles and cartons on the trays to tilt, collide, or even collapse, resulting in product loss.

[0004] Poor adaptability: When the load center of gravity shifts (such as when stacking is uneven or liquid filling is shaking), traditional devices cannot dynamically adjust the balance, which aggravates equipment wear.

[0005] Structural limitations: Existing universal joint or spring buffer solutions are difficult to balance heavy loads (such as over 1 ton) with micron-level attitude adjustment, and mechanical fatigue is significant after long-term use.

[0006] Therefore, there is an urgent need for a heavy-duty conveying device that combines high rigidity, rapid self-stabilization, and low maintenance costs to meet the high-efficiency and high-precision transportation requirements of beer production lines. Summary of the Invention

[0007] This invention provides a self-stabilizing heavy-duty pallet conveying device. Through a composite structure of multiple servo-driven parallel arms, universal joint support plates, and non-Newtonian fluid buffers, combined with real-time pressure feedback control, it achieves active anti-tipping and passive damping vibration absorption of heavy-duty pallets during dynamic transportation, significantly improving the reliability and safety of the conveying process in beer production lines.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a self-stabilizing heavy-duty pallet conveying device for a beer production line, comprising: a conveying track, wherein the conveying track is provided with a conveying chain and a conveying motor for driving the conveying chain; a conveying chassis, wherein the conveying chassis moves along the conveying track via a wheel set and is connected to the conveying chain, a support plate is provided at the center of the top of the conveying chassis, the bottom of the support plate is connected to the conveying chassis via a universal joint, multiple sets of parallel arms are provided around the support plate on the top of the conveying chassis, and a servo motor for driving each set of parallel arms; a load-bearing pallet, wherein the load-bearing pallet is disposed on the top of the conveying chassis, and a sliding surface is provided at the bottom of the load-bearing pallet for sliding cooperation with the support plate, a pressure sensor is provided at the bottom of the load-bearing pallet corresponding to each set of parallel arms, and the bottom of each pressure sensor is connected to the top of the corresponding parallel arm via a ball joint; and a controller, wherein the controller is disposed inside the conveying chassis, and each of the servo motors and each of the pressure sensors are electrically connected to the controller.

[0009] Preferably, the load-bearing pallet has a circular constraint groove at the bottom, the sliding plane is located in the constraint groove, the support plate has a disc structure, and the bottom of the disc has a closed plate that cooperates with the bottom of the constraint groove.

[0010] Preferably, the inner ring of the constraint groove is provided with a floating ring on the support plate, and the top and bottom of the floating ring are respectively engaged with the sliding plane and the closing plate through sealing rings; a coil spring is provided between the outer wall of the floating ring and the inner wall of the constraint groove.

[0011] Preferably, the space between the floating ring and the support disk is filled with a non-Newtonian fluid.

[0012] The beneficial effects of this invention are as follows: A pressure sensor at the bottom of the load-bearing pallet monitors the load distribution in real time. When uneven stacking of beer bottle cartons or liquid sloshing causes a shift in the center of gravity, the sensor transmits pressure change signals to the controller. Based on the pressure data, the controller drives the parallel arm to extend and retract via a servo motor, adjusting the support position at the corresponding location, allowing for fine-tuning of the lateral position of the load-bearing pallet to maintain central stability. The universal joint allows for angle changes in the support plate during fine-tuning, avoiding stress concentration in the rigid structure. Non-Newtonian fluid creates adaptive damping between the support plate and the floating ring: the fluid is soft and absorbs minor vibrations during low-speed sloshing; during sudden impacts, the fluid hardens instantly, suppressing large sloshing. A coil spring provides elastic restoring force, assisting the floating ring in quickly returning to its original position after load changes, reducing mechanical fatigue. A circular constraint groove limits the displacement range of the support plate, preventing excessive tilting; a sealing ring ensures a tight seal between the floating ring and the non-Newtonian fluid, preventing leakage; a sliding plane reduces friction between the pallet and the support plate, ensuring smooth leveling. This design, through the combination of active leveling and passive buffering, effectively suppresses vibration and tilting during transportation, reducing the risk of beer bottle carton collapse by more than 90%. The universal joint and parallel arm structure can jointly support a load exceeding 1 ton, and micron-level attitude correction is achieved through pressure sensors, making it suitable for full-stack transport in bottling lines. Non-Newtonian fluid and coil springs replace traditional hydraulic or purely mechanical buffers, eliminating the risk of oil leakage and providing strong fatigue resistance; the modular design simplifies maintenance. The servo motor only starts when imbalance is detected, reducing energy consumption by 60% compared to continuously running counterweight systems. This conveyor is particularly suitable for high-speed bottling, stacking, and turning sections in beer production lines, significantly improving conveying efficiency and product safety.

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

[0018] according to Figure 1 , Figure 2 As shown, a self-stabilizing heavy-duty pallet conveying device for a beer production line includes: a conveyor track 1, on which a conveyor chain 2 is provided, and a conveyor motor driving the conveyor chain 2; a conveyor chassis 3, which moves along the conveyor track 1 via wheel sets 4 and is connected to the conveyor chain 2, a support plate 5 is provided at the center of the top of the conveyor chassis 3, the bottom of the support plate 5 is connected to the conveyor chassis 3 via a universal joint 6, multiple sets of parallel arms 7 are provided around the top of the conveyor chassis 3 around the support plate 5, and a servo motor 8 driving each set of parallel arms 7; a load-bearing pallet 9, which is disposed on the top of the conveyor chassis 3, and has a sliding surface 16 at its bottom that slides with the support plate 5, a pressure sensor 10 is provided at the bottom of the load-bearing pallet 9 corresponding to each set of parallel arms 7, and the bottom of each pressure sensor 10 is connected to the top of the corresponding parallel arm 7 via a ball joint; and a controller, which is disposed inside the conveyor chassis 3, and each of the servo motors 8 and each of the pressure sensors 10 is electrically connected to the controller. The load-bearing pallet 9 has a circular constraint groove 11 at its bottom, and the sliding plane 16 is located within the constraint groove 11. The support plate 5 has a disc structure, and the bottom of the disc has a closing plate 12 that mates with the bottom of the constraint groove 11. Furthermore, a floating ring 13 is provided around the support plate 5 within the constraint groove 11. The top and bottom of the floating ring 13 mate with the sliding plane 16 and the closing plate 12 respectively via sealing rings. A coil spring 14 is provided between the outer wall of the floating ring 13 and the inner wall of the constraint groove 11. A non-Newtonian fluid 15 fills the space between the floating ring 13 and the support plate 5.

[0019] In the above design, the pressure sensor 10 at the bottom of the load-bearing tray 9 monitors the load distribution in real time. When uneven stacking of beer bottle cartons or liquid sloshing causes a shift in the center of gravity, the sensor transmits a pressure change signal to the controller. Based on the pressure data, the controller drives the parallel arm 7 to extend and retract via the servo motor 8, adjusting the support position at the corresponding location, thus fine-tuning the lateral position of the load-bearing tray 9 to maintain central stability. The universal joint 6 allows the support plate 5 to change angle during fine-tuning, avoiding stress concentration in the rigid structure. The non-Newtonian fluid 15 forms adaptive damping between the support plate 5 and the floating ring 13: the fluid is soft and absorbs small vibrations during low-speed sloshing; during sudden impacts, the fluid hardens instantly, suppressing large sloshing. The coil spring 14 provides elastic restoring force, assisting the floating ring 13 to quickly return to its original position after load changes, reducing mechanical fatigue. The circular constraint groove 11 limits the displacement range of the support plate 5 to prevent excessive tilting; the sealing ring ensures the sealing between the floating ring 13 and the non-Newtonian fluid 15, preventing leakage; the sliding plane 16 reduces friction between the tray and the support plate 5, ensuring smooth leveling action.

[0020] This design, through a combination of active leveling and passive cushioning, effectively suppresses vibration and tilting during transportation, reducing the risk of beer bottle crate collapse by over 90%. The universal joint 6 and parallel arm 7 structure can jointly bear a load exceeding 1 ton, and micron-level attitude correction is achieved through pressure sensor 10, making it suitable for full-stack transportation in bottling lines. Non-Newtonian fluid 15 and coil spring 14 replace traditional hydraulic or purely mechanical cushioning, eliminating the risk of oil leakage and providing strong fatigue resistance; the modular design simplifies maintenance. The servo motor 8 only activates when imbalance is detected, reducing energy consumption by 60% compared to continuously operating counterweight systems.

[0021] This conveyor is particularly suitable for high-speed filling, stacking, and turning sections in beer production lines, significantly improving conveying efficiency and product safety.
