[0002] Depalletizers are devices used to remove goods from a pile of goods and transfer them to other places. These devices play an important role in the warehousing and logistics industry, which can improve the efficiency and safety of cargo loading and unloading. In the carton production process, depalletizers are usually used to depalletize the stacked cardboard and feed it into the production line.
[0003] When the existing depalletizer depalletizes the upper cardboard, the higher cardboard pile is prone to collapse and fall due to uneven force. When depalletizing, the cardboard is moved by clamping both sides of the cardboard. When the clamping force is too small, the cardboard is easy to slide off. When the clamping force is too large, the cardboard is easy to be squeezed and damaged. Therefore, we propose an efficient automatic depalletizer to solve the above problems. Utility Model Content

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0022] Reference Figure 1 and Figure 2 As shown, a high-efficiency automatic depalletizer comprises a first bracket 1, a second bracket 2 and two frames 8 arranged at the lower ends of the first bracket 1 and the second bracket 2. The upper ends of the first bracket 1 and the second bracket 2 are fixedly connected with a top plate 3. The lower end of the top plate 3 is fixedly installed with four electric telescopic rods 4. The output end of the electric telescopic rod 4 is fixedly connected with a suction cup connection seat 5. The four electric telescopic rods 4 are respectively located at the four corners of the upper end of the suction cup connection seat 5. The suction cup connection seat 5 can be stably lifted and lowered under the drive of the electric telescopic rod 4. A vacuum pump 6 is fixedly installed in the middle of the end, and four evenly distributed vacuum suction cups 7 are fixedly connected to the lower end of the suction cup connecting seat 5. A vacuum cavity is opened inside the suction cup connecting seat 5. The output end of the vacuum pump 6 and the upper end of the vacuum suction cup 7 are both connected to the vacuum cavity. The vacuum suction cup 7 can be driven to descend through the electric telescopic rod 4 to make it fit on the surface of the cardboard. The vacuum pump 6 can be used to extract the air inside the vacuum cavity. As the air inside the vacuum cavity is extracted, negative pressure is formed inside the vacuum suction cup 7, and the cardboard is adsorbed on the vacuum suction cup 7.
[0023] A conveyor belt 9 is arranged between the two frames 8, and a fixed bracket 10 is fixedly connected to the upper right part of the two frames 8. A sliding groove 11 is opened at the upper end of the fixed bracket 10, and the first bracket 1 is slidably connected to the inside of the front sliding groove 11, and the second bracket 2 is slidably connected to the inside of the rear sliding groove 11.
[0024] The rear sliding groove 11 is internally rotatably connected with a screw rod 12 that passes through the lower left portion of the second bracket 2. The second bracket 2 is threadedly connected to the outer surface of the screw rod 12. The right end of the rear fixed bracket 10 is fixedly installed with a motor 14 for driving the screw rod 12 to rotate. The front sliding groove 11 is internally fixedly connected with a sliding rod 13 that passes through the lower left portion of the first bracket 1. The first bracket 1 is slidably connected to the outer surface of the sliding rod 13. The screw rod 12 is driven to rotate by the motor 14, so that the first bracket 1 and the second bracket 2 can move along the sliding groove 11, thereby driving the vacuum suction cup 7 to move along the conveying direction of the conveyor belt 9.
[0025] Reference Figure 3 As shown, a placing table 15 is fixedly connected between the two fixed brackets 10, and a fixed frame 16 is fixedly connected to the upper end of the placing table 15. The initial position of the vacuum suction cup 7 is located directly above the fixed frame 16. A storage door 17 is hinged at the right end of the fixed frame 16. A latch is provided on the outer side of the storage door 17, and the latch can fix the position of the storage door 17 when it is closed. A lifting cylinder 18 is fixedly installed at the lower end of the placing table 15, and the output end of the lifting cylinder 18 passes through the lower end of the placing table 15 and is fixedly connected to a push plate 19, which is slidably connected to the inside of the fixed frame 16. The lifting cylinder 18 is used to push the push plate 19 to slide upward along the inner wall of the fixed frame 16. Whenever the vacuum suction cup 7 takes a cardboard from the upper end of the fixed frame 16, the lifting cylinder 18 will push the push plate 19 to move upward for a distance, and the length of this distance is the thickness of a piece of cardboard.
[0026] Working principle: When in use, first open the storage door 17 and place the stacked cardboards on the inner side of the fixed frame 16, then close the storage door 17 and insert the latch, at this time, the lifting cylinder 18 will push the push plate 19 upward so that the upper end of the cardboard pile is flush with the upper end of the fixed frame 16, and then the electric telescopic rod 4 will drive the suction cup connecting seat 5 to move downward so that the vacuum suction cup 7 fits the upper end of the cardboard, at this time, the vacuum pump 6 will extract the air inside the vacuum chamber, as the air inside the vacuum chamber is extracted, negative pressure is gradually formed inside the vacuum suction cup 7, and the cardboard is adsorbed on the vacuum suction cup 7 under the action of the negative pressure. Then, the motor 14 drives the screw rod 12 to rotate, so that the first bracket 1 and the second bracket 2 can move along the sliding groove 11, thereby driving the vacuum suction cup 7 to move along the conveying direction of the conveyor belt 9. When the cardboard is completely above the conveyor belt 9, the motor 14 stops running, and the electric telescopic rod 4 drives the suction cup connecting seat 5 to continue to descend. When the cardboard is close to the surface of the conveyor belt 9, the vacuum pump 6 stops extracting air. At this time, the cardboard will fall on the surface of the conveyor belt 9 and be transported to the processing area under the action of the conveyor belt 9. Then the vacuum suction cup 7 will be reset driven by the motor 14 and the electric telescopic rod 4 and repeat the above operation.
