Description

Technical Field

[0001] This application relates to the field of palletizer feeding technology, and more specifically, to a high-efficiency palletizing device for palletizers. Background Technology

[0002] Palletizing refers to the process in the packaging and warehousing stage of industrial production where a palletizer, through specific devices and processes, automatically detects, adjusts the orientation of, and positions products that are disordered or inconsistent in position or direction on a conveyor belt, arranging them in an orderly manner. Then, through robotic arms, clamps, and other actuators, the products are picked up in an orderly manner and transported to designated pallets, storage locations, or transport vehicles to complete the stacking process.

[0003] Traditional palletizers often experience jamming and misalignment during operation when products are not neatly positioned on the conveyor belt. This leads to low palletizing efficiency and can damage products. Furthermore, existing palletizing devices require frequent manual intervention to reposition and reorganize products when they shift, increasing labor costs and reducing the overall automation level of production. In addition, the palletizing devices are not adaptable to different product specifications, and frequent changes in product specifications require a significant amount of time to adjust the palletizing devices, severely impacting production progress.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figures 1-6 A high-efficiency palletizing device for a palletizer includes a conveyor belt 1, a support frame 2 fixedly connected to one side of the conveyor belt 1, and a sorting component inside the support frame 2, which includes an adjustment unit and a centering unit.

[0030] The adjustment unit includes a fixed plate 3, and a reduction motor 4 is fixedly connected to one side of the support frame 2. The reduction motor 4 is used to drive the fixed plate 3 to rotate. Two clamping plates 10 are provided at the bottom of the fixed plate 3. The fixed plate 3 and the two clamping plates 10 are used to adjust the position of the product.

[0031] The centering unit includes two alignment frames 15, which are used to center the product.

[0032] Reference Figures 1-5 The output end of the geared motor 4 passes through one side of the support frame 2 and is fixedly connected to the top of the fixed plate 3. The fixed plate 3 has a cavity 5 inside, and a drive motor 6 is fixedly connected inside the cavity 5. A gear 7 is fixedly connected to the output end of the drive motor 6. Two rack plates 8 are provided inside the cavity 5, and both rack plates 8 mesh with the gear 7. Two limiting grooves 9 are provided on one side of the fixed plate 3. Connecting blocks 11 are slidably connected inside the two limiting grooves 9. One side of each connecting block 11 is fixedly connected to one side of the corresponding rack plate 8, and the other side of each connecting block 11 is fixedly connected to one side of the corresponding clamping plate 10. Each clamping plate 10 has a protective pad 12 on one side, and each protective pad 12 is made of elastic material. A vision sensor 19 is provided at the bottom of the fixed plate 3, and a pressure sensor is provided on the inner wall of each clamping plate 10.

[0033] The product placement can be uniformly adjusted by the adjustment unit. Specifically, when the product is conveyed to the bottom of the adjustment unit by the conveyor belt 1, the vision sensor 19 at the bottom of the fixed plate 3 collects the product's position and orientation data in real time and transmits it to the control system. After the control system determines that the product orientation needs to be adjusted, the drive motor 6 starts, and its output drives the gear 7 to rotate in the cavity 5 of the fixed plate 3. Since both rack plates 8 are meshed with the gear 7, when the gear 7 rotates, the two rack plates 8 will move in opposite directions. Through the connecting block 11, the clamping plate 10 slides towards each other in the limiting groove 9. During this process, the pressure sensor on the inner wall of the clamping plate 10 monitors the contact pressure with the product in real time and converts the pressure signal into an electrical signal to feed back to the control system. When the pressure reaches the preset threshold, it indicates that the product has been firmly clamped. The control system then controls the drive motor 6 to stop working. Immediately afterwards, the reduction motor 4 runs, and its output drives the fixed plate 3 to rotate, thereby driving the clamped product to rotate synchronously until the product reaches the preset orientation.

[0034] The adjustment unit enables automated and precise adjustment of product placement and orientation, effectively solving the problem of inconsistent product orientation and position on the conveyor belt. This lays a solid foundation for subsequent centering and palletizing processes, significantly improving palletizing efficiency and accuracy. Furthermore, the vision sensor 19 and pressure sensor monitor product status in real time, ensuring stable product clamping while preventing damage due to excessive clamping force, thus reducing product loss. Meanwhile, the gear 7, rack and pinion plate 8, and clamping plate 10 ensure the stability and reliability of the clamping action, reducing the probability of equipment failure. In addition, the unit can be flexibly adjusted according to control system commands to adapt to the orientation adjustment needs of various product specifications, eliminating the need for frequent manual intervention, significantly reducing labor costs, and enhancing the adaptability of the palletizing device to different production scenarios.

[0035] Reference Figures 1-4 Support plates 13 are fixedly connected to both sides of the support frame 2. An electric push rod 14 is fixedly connected to the top of each support plate 13. The output end of each electric push rod 14 is fixedly connected to one side of the corresponding correction frame 15. There is a gap between the bottom of each correction frame 15 and the surface of the conveyor belt 1. Multiple rollers 16 are rotatably connected to one side of each correction frame 15. The outer wall of each roller 16 is set as a smooth surface. Multiple telescopic rods 17 are fixedly connected between each correction frame 15 and the support frame 2. An inclined plate 18 is provided at one end of each correction frame 15 near the fixed plate 3.

[0036] The centering unit can adjust the distance between the two alignment frames 15 according to different product specifications, ensuring the orderly feeding of products into the stack. Specifically, after the products are aligned by the adjustment unit and conveyed to the centering unit, the control unit calculates the required distance between the two alignment frames 15 based on the product specifications and position data fed back by the vision sensor 10. Then, the control unit sends a command to the electric push rod 14, causing the output end of the electric push rod 14 to extend and retract, moving the alignment frames 15 along the guide direction of the telescopic rod 17, thereby adjusting the distance between the two alignment frames 15. During this process, the telescopic rod 17 provides stable support and guidance, preventing product deviation. When the alignment frame 15 moves, it deviates. After the alignment frame 15 moves into place, the product continues to move forward with the conveyor belt 1. The side of the product first contacts the inclined plate 18 at one end of the alignment frame 15. The inclination of the inclined plate 18 guides the product to move between the two alignment frames 15, reducing the impact force generated by the collision between the product and the alignment frame 15. As the product moves further, its side contacts the multiple rollers 16 rotatably connected on the alignment frame 15. Since the outer wall of the rollers 16 is smooth and can rotate freely, it reduces friction and ensures that the product can move smoothly between the alignment frames 15. Finally, the product is accurately centered in the center of the conveyor belt 1, ensuring the orderly stacking of the product.

[0037] The centering unit can dynamically and adaptively adjust the spacing of the alignment frame according to product specifications and position, effectively solving problems such as stacking misalignment and skewing caused by positional deviations when products of different sizes are being stacked, thus enhancing stacking quality and stability. The cooperation between the electric push rod 14 and the telescopic rod 17 ensures the accuracy and reliability of the alignment frame movement, reducing vibration and errors during equipment operation. Furthermore, the inclined plate 18 and smooth rollers 16 not only flexibly guide and center the products, but also significantly reduce the risk of surface wear and collision damage. In addition, this unit replaces manual intervention with automated control, adapts to the rapid switching of multiple product specifications, reduces changeover adjustment time, and improves the continuous operation capability of the production line.

[0038] Working principle: When the product is conveyed to the adjustment unit by the conveyor belt 1, the vision sensor 19 at the bottom of the fixed plate 3 collects the product position and orientation data in real time and transmits it to the control system. After the control system determines that the product orientation needs to be adjusted, the drive motor 6 starts, and its output end drives the gear 7 to rotate in the cavity 5 of the fixed plate 3. Since both rack plates 8 are meshed with the gear 7, when the gear 7 rotates, the two rack plates 8 will move in opposite directions. Through the connecting block 11, the clamping plate 10 slides towards each other in the limiting groove 9. During this process, the pressure sensor on the inner wall of the clamping plate 10 monitors the contact pressure with the product in real time and converts the pressure signal into an electrical signal to feed back to the control system. When the pressure reaches the preset threshold, it indicates that the product has been firmly clamped. The control system then controls the drive motor 6 to stop working. Then, the reduction motor 4 runs, and its output end drives the fixed plate 3 to rotate, thereby driving the clamped product to rotate synchronously until the product reaches the preset orientation.

[0039] After the product is aligned by the adjustment unit and then conveyed to the centering unit, the control unit calculates the required distance between the two alignment frames 15 based on the product specifications and position data fed back by the vision sensor 10. Subsequently, the control unit sends a command to the electric push rod 14, causing its output end to extend and retract, moving the alignment frames 15 along the guide direction of the telescopic rod 17, thereby adjusting the distance between the two alignment frames 15. During this process, the telescopic rod 17 provides stable support and guidance, preventing the alignment frames 15 from shifting during movement. Once the alignment frames 15 are in place, the product... As the product continues to move forward with the conveyor belt 1, its side first contacts the inclined plate 18 at one end of the alignment frame 15. The inclination of the inclined plate 18 guides the product to move between the two alignment frames 15, reducing the impact force generated by the collision between the product and the alignment frame 15. As the product moves further, its side contacts the multiple rollers 16 rotatably connected on the alignment frame 15. Since the outer wall of the rollers 16 is smooth and can rotate freely, it reduces friction and ensures that the product can move smoothly between the alignment frames 15. Finally, the product is accurately centered in the center of the conveyor belt 1, ensuring the orderly stacking of the product.

[0040] The aforementioned vision sensor 19, pressure sensor, and control unit are mature technologies in this field, and their specific working principles, internal structures, and common installation and wiring methods will not be elaborated here.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
