Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard box production equipment technology, and in particular to a cardboard box stacking device for cardboard box production. Background Technology
[0002] Currently, in the carton production process, cartons are conveyed by rollers to a pre-set platform that a robotic arm can grasp. Heavy cartons are prone to positional deviations during conveyance due to a shift in the center of gravity, leading to damage when the robotic arm grasps them. To address this, a carton palletizing device is used to improve this problem. The typical equipment in the current carton production equipment technology field is the conveyor belt palletizer. A conveyor belt palletizer typically consists of a roller conveyor, fixed limit blocks, and a fixed robotic arm. Cartons are conveyed to a preset position by the rollers. After the mechanical limit blocks perform initial positioning of the cartons, the robotic arm grasps and stacks them according to a fixed trajectory, thus completing the entire palletizing process.
[0003] Most conveyor-belt palletizing machines currently in use have limitations during roller conveying. When heavy cartons deviate in position due to a shift in their center of gravity, the rollers cannot correct the deviation of the heavy cartons during rotation. This can lead to damage to the cartons by the robotic arm during gripping due to positional errors. Furthermore, when the cartons reach the designated gripping platform, the robotic arm may fail to grip the bottom of the cartons, potentially damaging the outer shell. Therefore, a carton palletizing device for carton production is proposed to address these issues. Utility Model Content

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0030] Reference Figures 1-3 A cardboard box stacking device for cardboard box production includes a perforated platform 1. A support circular plate 15 is slidably connected to the top of the perforated platform 1. The perforated platform 1 is used to temporarily store heavy cardboard boxes that are conveyed. The support circular plate 15 can lift the heavy cardboard boxes to a certain height for easy gripping. The output end of a hydraulic cylinder 14 is fixedly connected to the bottom of the support circular plate 15, which can lift the support circular plate 15 and move the heavy cardboard boxes above. A fixing chamber 5 is fixedly connected to the bottom of the hydraulic cylinder 14 to fix the hydraulic cylinder 14 and the support circular plate 15, ensuring that the two have sufficient relative force to lift the heavy cardboard boxes above. The box has multiple evenly distributed support legs 2 fixedly connected to the bottom of the perforated platform 1. Multiple evenly distributed support frames 4 are fixedly connected to the left side of the perforated platform 1. The front support frame 4 has multiple evenly distributed limiting circular holes in its center. The rear support frame 4 has evenly distributed grooves on its top. A fixing chamber 13 is fixedly connected to the bottom of the support frame 4. A circular hole is left at the rear of the fixing chamber 13. A motor 6 is threadedly connected to the rear of the fixing chamber 13. The motor 6 extends through the circular hole at the rear of the fixing chamber 13 and into its interior. A bidirectional threaded rod 7 is fixedly connected to the drive end of the motor 6. Multiple evenly distributed drive sliders 9 are connected to the outer periphery of the threaded rod 7. A limit block 8 is slidably connected to the middle of the bidirectional threaded rod 7. When the motor 6 starts, the drive sliders 9 on the outer periphery of the bidirectional threaded rod 7 move along the threaded rod. The limit block 8 can prevent the drive sliders 9 from colliding when they come together. Multiple evenly distributed correction brackets 10 are fixedly connected to the top of the drive sliders 9. When the drive sliders 9 move, the correction brackets 10 will move with them. Multiple evenly distributed correction plates 11 are fixedly connected to the top of the correction brackets 10, which can correct the directional deviation of heavy cartons and ensure that they return to their original position. To move onto the correct trajectory, the bottom of the support frame 4 is fixedly connected to multiple evenly distributed support legs 2 3, and the top of the support frame 4 is slidably connected to multiple evenly distributed center rods 20. The center rods 20 correspond one-to-one with the central limiting round holes inside the front support frame 4, and the right outer periphery is placed in the groove at the top of the rear support frame 4. The outer periphery of the center rods 20 is fixedly connected to multiple evenly distributed conveyor rollers 12, which can drive heavy cartons to move to the perforated platform 1. The fixed compartment 1 5 is fixedly connected to the support legs 1 2 around its periphery, and the limiting blocks 1 8 are fixedly connected to the left and right sides of the fixed compartment 2 13.
[0031] Reference Figures 1-3A motor 21 is fixedly connected to the left side of the second support leg 3. A connecting rod 24 is fixedly connected to the drive end of the motor 21. When the motor 21 starts, it drives the connecting rod 24 to rotate. Multiple evenly distributed pulleys 23 are fixedly connected to the outer periphery of the connecting rod 24. Multiple evenly distributed pulleys 25 are slidably connected to the rear of the support frame 4. Multiple evenly distributed belts 22 are sleeved on the outer periphery of pulleys 23 and 25. The top of the belts 22 is sleeved on the outer periphery of pulleys 25, and the bottom of the belts 22 is sleeved on the outer periphery of pulleys 23. When the connecting rod 24 rotates, it drives pulleys 23 to rotate. Pulleys 23 and belts 22 will have a linkage effect, thereby driving pulleys 25 above to rotate. A limit block 26 is fixedly connected to the right side of the second support leg 3. In order to stabilize the rotation of the connecting rod 24, a protective plate 27 is fixedly connected to the rear of the second support leg 3 to prevent debris from falling and affecting the equipment, thereby causing damage to the equipment. The left side of the protection plate 27 is fixedly connected to the right side of the motor 21, and the right side of the protection plate 27 is fixedly connected to the left side of the limit block 26. The right side of the perforated platform 1 is fixedly connected to the baffle 16. In order to prevent heavy cartons from falling off when they are conveyed to the perforated platform 1, the right side of the support leg 2 is fixedly connected to the positioning plate 17. The top of the positioning plate 17 is equipped with a robotic arm 18 for gripping cartons. The front of the support leg 2 is slidably connected to a tray 19 for storing cartons for convenient subsequent transportation.
[0032] Working principle: First, when a heavy cardboard box enters the device, motor 21 is started, which drives pulley 23 to rotate via connecting rod 24. Pulley 23 drives pulley 25 to rotate via belt 22, causing conveyor roller 12 to rotate in conjunction with the support of center rod 20, smoothly conveying the cardboard box to the top of perforated platform 1. When the cardboard box deviates in position due to center of gravity shift during conveying, motor 6 is started, which drives bidirectional threaded rod 7 to rotate. The transmission sliders 9 on both sides move towards the center along the threaded rod under the restriction of limit block 8. The two sides move synchronously, thereby driving the correction plate 11 on the correction bracket 10 to form a dynamic clamping and guiding effect. The correction plate 11 gradually corrects the displacement deviation of the heavy carton by contacting the side of the carton, ensuring that the heavy carton accurately enters the perforated platform 1 along the direction. During this process, the protection plate 27 isolates external debris from interference, ensuring that the outside will not interfere with the operation of internal parts. The limit block 26 can stabilize the rotation of the connecting rod 24, ensuring that the two ends of the motor 21 will not shake or become unstable due to the shift of the center of gravity, thereby affecting the operation of the machine and causing damage to the machine.
[0033] Once the carton is fully inside the perforated platform 1, the baffle 16 prevents it from sliding off the platform. At this point, the hydraulic cylinder 14 is activated to push the support plate 15 vertically upward through the holes in the platform 1, lifting the carton to a predetermined height. This action exposes the bottom of the carton, allowing the robotic arm 18 to extend its gripper and precisely grasp the bottom, preventing deformation and damage due to uneven gripping force. During the lifting process, the support leg 2 and the fixed compartment 5 provide strong support for the hydraulic cylinder 14, ensuring that the support plate 15 can smoothly lift and lower the heavy carton. After the robotic arm 18 grasps the carton, it is placed on the pallet 19 according to a preset trajectory. After a single stacking is completed, the hydraulic cylinder 14 resets, the robotic arm 18 returns to its original position, and the support plate 15 descends back into the perforated platform 1. The device then enters the next working cycle, thus completing the entire stacking process of the carton.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
