Abstract
Description
Technical Field
[0001] This utility model relates to the field of palletizing device technology, and in particular to a material box stacking and unloading mechanism. Background Technology
[0002] Currently, in many industrial production and logistics warehousing scenarios, the loading and unloading of boxes still heavily relies on manual operation, especially using heavy-duty handling equipment such as forklifts. This method of operation not only places a great physical burden on operators and increases labor intensity, but also requires workers to frequently drive forklifts to different areas of the warehouse to move, stack, and destacking boxes. This repetitive physical labor can easily lead to physical fatigue and may also cause workplace injuries due to prolonged high-intensity work, such as sprains, strains, or even more serious injuries.
[0003] Furthermore, the efficiency of manually operating forklifts for loading and unloading operations is limited by a variety of factors, including the operator's skill level, the complexity of the working environment (such as narrow aisles and obstructed visibility), and the performance limitations of the forklift itself. These factors combined often slow down the entire production line, making it difficult to meet the demands of modern manufacturing for rapid market response and shorter delivery cycles. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a material bin stacking and unloading mechanism. This mechanism, through the cooperation of multiple sensors, achieves automatic stacking, increasing the degree of automation compared to existing technologies.

A drive assembly is installed at the upper end of the U-shaped lifting frame. The drive assembly consists of a transmission box and a drive motor at the top. The output shaft of the drive motor extends into the transmission box and is equipped with a first bevel gear. Rotary shafts are rotatably connected to the opposite sides of the two first mounting seats. The opposite ends of the two rotating shafts extend into the transmission box and are equipped with second bevel gears. Racks are fixedly connected to the inner walls of both sides of the frame. The other ends of the two rotating shafts pass through the corresponding first mounting seats and are fixedly connected with transmission gears.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-5 A material bin stacking and unloading mechanism includes a frame 1, two first sensors 7, two second sensors 8, and two third sensors 9 installed diagonally on the frame 1. The two first sensors 7, the two second sensors 8, and the three third sensors 9 are used together to control the subsequent drive motor, the first cylinder 18, and the second cylinder 21.
[0023] The system also includes a lifting assembly for lifting the material box. The lifting assembly includes a U-shaped lifting frame 3. The frame 1 is U-shaped and has multiple guide rails 4 installed on both inner walls. Multiple slide rail moving seats 5 are installed on both sides of the U-shaped lifting frame 3. Each slide rail moving seat 5 cooperates with the corresponding guide rail 4. Two first mounting seats 12 are symmetrically fixedly connected to the upper end of the U-shaped lifting frame 3. A drive assembly 10 is installed on the upper end of the U-shaped lifting frame 3. The drive assembly 10 consists of a transmission box and a drive motor at the top. The output shaft of the drive motor extends into the transmission box and is equipped with a first bevel gear. Rotary shafts 11 are rotatably connected to the opposite sides of the two first mounting seats 12. The opposite ends of the two rotating shafts 11 extend into the transmission box and are equipped with second bevel gears. Racks 14 are fixedly connected to both inner walls of the frame 1. The other ends of the two rotating shafts 11 pass through the corresponding first mounting seats 12 and are fixedly connected with transmission gears 13. The first bevel gear meshes with the two second bevel gears, and the transmission gears 13 mesh with the racks 14.
[0024] Among them, two support modules are symmetrically installed at the lower end of the lifting component. The two support modules are used to insert into the bottom of the material box and facilitate subsequent lifting and stacking. The support module includes a lifting base plate 15 fixedly connected to the lower end of the horizontal part of the U-shaped lifting frame 3. A first pad 19 is installed at the upper end of the lifting base plate 15. A first cylinder 18 is installed on one side of the first pad 19. A moving plate 16 is fixedly connected to the telescopic end of the first cylinder 18. A support plate 17 is fixedly connected to the upper end of the moving plate 16. To increase the actual stability, two linear slide rails are also installed at the upper end of the lifting base plate 15. The slide rail seat of the two linear slide rails is fixedly connected to the moving plate 16.
[0025] It also includes a side guard assembly, which is used to guide the movement of the material box and ensure that the rear material box is always parallel to the two side walls of the frame 1 during the stacking process. The side guard assembly includes two L-shaped side guard plates 6 that are symmetrically fixedly connected to the front side of the frame 1.
[0026] The system also includes two blocking components, which are symmetrically arranged on the rear side of the frame 1. The blocking components are used to block the movement of the material box. Each blocking component includes a mounting side plate 2 fixedly connected to the rear side of the frame 1. A second pad 22 is fixedly connected to the rear side of the mounting side plate 2. A dovetail groove plate 20 is fixedly connected to the telescopic end of the second pad 22. A baffle 23 is fixedly connected to the other side of the dovetail groove plate 20. A guide strip that cooperates with the dovetail groove plate 20 is fixedly connected to the rear side of the mounting side plate 2.
[0027] In this invention, during operation, a portion of the roller conveyor is located below the frame 1. The drive motor drives the lifting assembly downwards to a designated position (using the transmission of gear 13 and rack 14). The two second cylinders 21 extend simultaneously, and the two baffles 23 extend. The roller conveyor transports the material box to the designated position (blocked by the baffles 23). The two first sensors 7 detect signals, and the two first cylinders 18 of the lifting assembly extend simultaneously, driving the two moving plates 16 to insert into the bottom of the material box (the material box has a box structure with a groove at the bottom, and part of its contact surface with the roller conveyor has a gap to facilitate the insertion of the moving plates 16). The drive motor drives the lifting assembly to move the material box upwards to the designated position. The roller conveyor continues to transport the second material box to the baffle 23. At this time, the two first sensors 7 and the two second sensors 8 simultaneously... Upon detecting a signal, the drive motor moves the lifting assembly downwards to stack the first bin onto the second bin, completing the bin stacking. The two first cylinders 18 retract, and the drive motor continues to move the lifting assembly downwards to the bottom of the second bin. The two first cylinders 18 extend, causing the two moving plates 16 to insert into the bottom of the second bin. The drive motor then moves the stacked bins upwards to the designated position. The roller conveyor continues to transport the third bin to the baffle 23. Simultaneously, the two first sensors 7, the second sensor 8, and the third sensor 9 detect a signal, and the drive motor moves the lifting assembly downwards to stack the two bins onto the third bin. The two first cylinders 18 retract, followed by the two second cylinders 21, releasing the baffle 23. The three stacked bins then flow to the next workstation via the roller conveyor.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
