The palletizing robot accurately loads the material from the first conveyor belt onto a vehicle positioned to one side of the support platform. As the support platform slides, the palletizing robot moves closer to or further away from the second conveyor belt. This design allows the relative position of the palletizing robot, the second conveyor belt, and the vehicle to be adjusted according to actual needs, adapting to different work scenarios and vehicle sizes. This reduces the number of vehicle adjustments required during loading, allowing the vehicle to effectively utilize the loader without requiring additional manual adjustments, thus reducing operational complexity and time costs.

[0048] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0049] Example, see Figures 1 to 3 , which is an embodiment of the present utility model, proposes an automatic loading machine for loading materials 25 on a material conveyor belt 24 onto a vehicle 26, including a guide rail 1, a support platform 2, a first conveyor belt 3, a second conveyor belt 4, and a palletizing robot 5. The support platform 2 is slidably arranged on the guide rail 1; the first conveyor belt 3 is located above the support platform 2, and the conveying direction of the first conveyor belt 3 is the same as the length direction of the guide rail 1; the second conveyor belt 4 is located above the guide rail 1 and is inclined. The upper end of the second conveyor belt 4 is used to connect with the material conveyor belt 24, and the lower end of the second conveyor belt 4 is connected with the first conveyor belt 3; the palletizing robot 5 is arranged on the support platform 2, and is located at the end of the support platform 2 away from the material conveyor belt 24, for loading the material 25 delivered by the first conveyor belt 3 onto a vehicle 26 located on one side of the support platform 2. After the support platform 2 slides, the palletizing robot 5 approaches or moves away from the second conveyor belt 4.

[0050] In this embodiment, the guide rail 1 provides a stable moving track for the support platform 2, ensuring that the support platform 2 remains stable and accurately oriented during movement. The first conveyor belt 3 is set horizontally, and the second conveyor belt 4 is set at an angle. The length direction of the first conveyor belt 3 and the second conveyor belt 4 is the same as the length direction of the guide rail 1. After the material 25 enters the second conveyor belt 4 from the material conveyor belt 24, due to the inclination angle of the slope, the material 25 slides smoothly onto the first conveyor belt 3 under the combined action of gravity and the friction of the conveyor belt. The first conveyor belt 3 is driven by a motor and other means to transport the material 25 at a stable speed in the direction of the stacking robot 5, which can realize the transition of material 25 at different heights and angles. The stacking robot 5 accurately loads the material 25 delivered by the first conveyor belt 3 onto the vehicle 26 located on one side of the support platform 2 through the grabbing, carrying and other actions of the robotic arm. When the support platform 2 slides, the palletizing robot 5 will move closer to or away from the second conveyor belt 4. This design can adjust the relative positions of the palletizing robot 5, the second conveyor belt 4, and the vehicle 26 according to actual needs, and can adapt to different working scenarios and vehicle 26 sizes, thereby reducing the number of times the position of the vehicle 26 is adjusted during the loading process, so that the vehicle 26 can effectively utilize the loader without the need for additional manual adjustment, which can reduce the complexity and time cost of the operation.

[0051] The present invention, through the coordination of the first conveyor belt 3 and the second conveyor belt 4, can realize the continuous transportation of materials 25 from the material conveyor belt 24 at a high position to the vehicle 26 at a low position, greatly improving the efficiency of material 25 transportation. It avoids the tedious and inefficient manual handling, and can reduce labor costs and labor intensity. The sliding function of the support platform 2 enables the stacking robot 5 to be flexibly adjusted according to the position and size of different vehicles 26, which can better adapt to different working environments and task requirements, and improve the versatility and adaptability of the entire equipment. The stacking robot 5 has high-precision motion control capabilities and can accurately load materials 25 onto the vehicle 26, which can ensure the neatness and stability of stacking, improve the loading efficiency and space utilization of the vehicle 26, and reduce the manual participation in the process of handling and stacking materials 25, reducing the risk of safety accidents caused by human error. At the same time, the stable operation of the stacking robot 5 can also improve the safety and reliability of the production process. The equipment has a high degree of automation and can be seamlessly connected with other production links, which can optimize the entire production process, improve production efficiency, reduce production costs, and bring higher economic benefits to the enterprise.

[0052] Furthermore, if Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, guide rails 1 are provided on both sides of the support platform 2, and also include racks 6 and gears 7. A rack 6 is provided on each guide rail 1, and the length direction of the rack 6 is the same as the length direction of the guide rail 1; at least two gears 7 are provided on both sides of the support platform 2, and all gears 7 located on the same side of the support platform 2 are arranged along the length direction of the support platform 2. The gears 7 are rotatably connected to the support platform 2, and the axis of the gears 7 is horizontally arranged, and the axis direction of the gears 7 is perpendicular to the length direction of the guide rail 1. The gears 7 are engaged with the racks 6 located below them. When the support platform 2 needs to move, the support platform 2 slides on the guide rail 1 by rotating the gears 7 on the racks 6. A stable and precise movement method is provided to ensure that the support platform 2 can accurately move to the desired position along the guide rail 1. The cooperation between the gears 7 and the racks 6 can withstand a large load, ensuring that it can still operate smoothly while carrying materials 25 and equipment.

[0053] Furthermore, if Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, gear 7 is provided with a limiting collar 8, which is coaxially arranged with gear 7. Guide rail 1 is located between rack 6 and limiting collar 8, with the lowest point of limiting collar 8 located above the bottom surface of guide rail 1. Limiting collar 8 limits the vertical displacement of gear 7, preventing gear 7 from disengaging from rack 6 due to vibration of support platform 2 or other factors. This ensures that gear 7 always maintains a good meshing state with rack 6, ensuring the continuity of the movement process and improving the stability and reliability of the equipment.

[0054] Furthermore, if Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the limiting protrusion 8 is located outside the gear 7, and the outer side surface of the guide rail 1 has a slide groove 9. It also includes a limiting wheel 10, which is rotatably arranged outside the limiting protrusion 8 and forms a sliding fit with the slide groove 9. During the movement of the support platform 2, the limiting wheel 10 rolls in the slide groove 9, further enhancing the stability of the support platform 2, reducing the shaking and deviation of the support platform 2 in the vertical and horizontal directions, and improving the accuracy and safety of the equipment.

[0055] Furthermore, if Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, it also includes a transmission shaft 11, a running wheel 12, and a travel drive mechanism 13. The transmission shaft 11 is rotatably arranged at the bottom of the support platform 2. The axial direction of the transmission shaft 11 is perpendicular to the length direction of the guide rail 1. There are at least two transmission shafts 11, and all transmission shafts 11 are arranged along the length direction of the support platform 2. Running wheels 12 are provided at both ends of the transmission shaft 11. The lowest point of the running wheel 12 is located below the lowest point of the gear 7. The diameters of the gear 7 and the running wheel 12 are configured so that after the gear 7 is engaged with the rack 6, the lowest point of the running wheel 12 is located above the lowest point of the guide rail 1. After the gear 7 is separated from the rack 6, the lowest point of the running wheel 12 is flush with the lowest point of the guide rail 1. The travel drive mechanism 13 is provided on the support platform 2 and is in transmission connection with the transmission shaft 11. The travel drive mechanism 13 drives the running wheel 12 to rotate, thereby realizing the movement of the support platform 2. Two movement modes are provided. When precise position adjustment is required, the gear 7 and the rack 6 are engaged for transmission; when rapid movement is required or in specific circumstances, the gear 7 and the rack 6 are separated and the travel wheel 12 is used for movement, which can increase the flexibility of the system.

[0056] Furthermore, if Figure 1 、 Figure 2 and Figure 6As shown, the equipment further includes material conveying rollers 14 and a rotary drive mechanism 15. The material conveying rollers 14 are rotatably mounted above the support platform 2 and located between the first conveyor belt 3 and the palletizing robot 5. There are multiple material conveying rollers 14, all of which are arranged along the length of the support platform 2, and the length of the material conveying rollers 14 is arranged along the width of the support platform 2. The rotary drive mechanism 15 is located above the support platform 2 and is in transmission connection with the material conveying rollers 14. The rotary drive mechanism 15 drives the material conveying rollers 14 to rotate, conveying the material 25 on the first conveyor belt 3 to the palletizing robot 5, thereby acting as an intermediate transition conveyor, allowing the material 25 to be more smoothly conveyed from the first conveyor belt 3 to the working area of the palletizing robot 5. The rotation speed of the material conveying rollers 14 can be adjusted as needed to accommodate different production rhythms and material characteristics.

[0057] Furthermore, if Figure 1 、 Figure 2 and Figure 6 As shown, the apparatus further includes a mounting frame 16, which is disposed on the support platform 2. The material conveying roller 14 is rotatably connected to the mounting frame 16, and the rotary drive mechanism 15 is disposed on the mounting frame 16. The mounting frame 16 provides a mounting and supporting structure for the material conveying roller 14 and the rotary drive mechanism 15, thereby making the installation of the material conveying roller 14 and the rotary drive mechanism 15 more stable, ensuring the normal operation of the equipment, facilitating the maintenance and overhaul of the equipment, and improving the maintainability of the equipment.

[0058] Furthermore, if Figure 6 and Figure 7 As shown, the system also includes laser beam switches 17 and a control module 18. Multiple pairs of laser beam switches 17 are positioned along the length of mounting frame 16, with a material conveying channel defined between each pair. The output of each laser beam switch 17 is connected to the input of control module 18, which in turn is connected to the controlled end of rotary drive mechanism 15. When material 25 passes through the material conveying channel, it blocks the light from the laser beam switches 17. Control module 18 precisely controls the operating state of rotary drive mechanism 15, and thereby the operating state of material conveying roller 14, based on the material's position and quantity. This enables automatic detection and control of material conveying, prevents accumulation and blockage of material 25, and improves the level of automation in production.

[0059] Furthermore, if Figure 1 and Figure 2As shown, the equipment further includes a first support frame 19, a second support frame 20, and a guide plate 21. The first support frame 19 is disposed on the support platform 2, and the first conveyor belt 3 is disposed on the first support frame 19. The second support frame 20 is located obliquely above the first support frame 19, and the second conveyor belt 4 is disposed on the second support frame 20. The guide plate 21 is located between the second support frame 20, the upper end of the guide plate 21 is connected to the lower end of the second support frame 20, and the lower end of the guide plate 21 overlaps the first support frame 19. The guide plate 21 serves to guide the material 25 to smoothly transition from the second conveyor belt 4 to the first conveyor belt 3, ensuring a smooth transition of the material 25 between the different conveyor belts, reducing the scattering and damage of the material 25, improving the efficiency and reliability of the material 25 conveying, and ensuring the continuous operation of the entire equipment.

[0060] Furthermore, if Figure 1 、 Figure 2 and Figure 8 As shown, the conveyor belt 22 further includes a material blocking and reversing belt 22 and a material guide trough 23. The material blocking and reversing belt 22 is positioned above the material conveyor belt 24. The conveying surface of the material blocking and reversing belt 22 faces the entry end of the material conveyor belt 24, and the distal end of the conveying surface of the material blocking and reversing belt 22 is inclined toward the distal end of the material conveyor belt 24. The upper end of the material guide trough 23 is positioned on one side of the material conveyor belt 24, between the conveying surface of the material blocking and reversing belt 22 and the entry end of the material conveyor belt 24, and the lower end of the material guide trough 23 is connected to the upper end of the second conveyor belt 4. The material blocking and reversing belt 22 guides the material 25 into the material guide trough 23, which then conveys the material 25 to the second conveyor belt 4. This effectively controls the flow direction of the material 25, ensuring that the material 25 accurately enters the second conveyor belt 4, thereby improving the accuracy and efficiency of the material 25 conveying process. The speed and angle of the material blocking and reversing belt 22 can be adjusted as needed to accommodate different material characteristics and production requirements.
