Description

Technical Field

[0001] The utility model relates to the technical field of carton palletizers, in particular to a clamp for a carton palletizer. Background Art

[0002] Currently, palletizing operations in my country use two methods: manual handling and palletizing. Manual handling, however, is being phased out due to its high labor intensity, low efficiency, and poor safety. Palletizing machines use robotic arms to grab cartons and arrange them on pallets or boards for automatic stacking. This intelligent, simple, and easy-to-use operation significantly reduces labor and workload.

[0003] Conventional palletizer clamps all use L-shaped clamping plates to lift the bottom of cartons for transfer and stacking. When stacking cartons, these clamping plates remain at the bottom of the cartons, creating significant friction between them. This makes it difficult for the clamping plates to detach from the cartons. Furthermore, it's possible for one clamping plate to detach while the other remains attached, causing the cartons to be stacked askew and unevenly, impacting work efficiency. To address these issues, the present application proposes a carton palletizer clamp. Utility Model Content

Start the vacuum pump 16, so that the connecting pipe 18 and the connecting pipe 2 19 respectively extract the air in the vacuum box 14 and the vacuum box 2 20, so that the pressure difference between the external environment of the vacuum box 14 and the vacuum box 2 20 causes the carton to be adsorbed on the fixed plate 15 and the fixed plate 2 21, thereby facilitating the fixation of the carton and avoiding falling during the transportation process.

[0021] Preferably, the lateral movement component includes a mounting vertical plate 4 fixedly mounted on the top of the connecting plate 3, a servo motor 5 fixedly arranged on the left side of the mounting vertical plate 4, a rotating screw 6 fixedly arranged on the output end of the servo motor 5, a movable screw sleeve 7 threadedly arranged on the surface of the rotating screw 6, a movable plate 8 fixedly arranged on both the front and rear sides of the movable screw sleeve 7, a telescopic cylinder 11 fixedly mounted on the top of the movable plate 8, a guide sleeve 9 fixedly arranged on the bottom of the movable plate 8, a guide slide 10 slidingly arranged inside the guide sleeve 9, and the guide slide 10 fixedly mounted on the top of the connecting plate 3. The driving output end drives the rotating screw 6 to rotate, so that the movable screw sleeve 7 moves to the right along the thread direction of the rotating screw 6 surface, so that the movable plate 8 drives the telescopic cylinder 11 to move to the right, and the position direction of the movable plate 8 is limited by the guide sleeve 9 and the guide rail 10, so that the T-shaped fixed plate 12 pushes the vacuum box 14 to approach the carton through the mounting column 13, and the vacuum box 14 pushes the fixed plate 15 to contact with the side of the carton, thereby facilitating the pushing of the fixed plate 15 to contact with the carton, and facilitating the fixed transportation and stacking of cartons of different volumes.

[0022] Preferably, the mounting assembly includes a T-shaped fixing plate 12 fixedly mounted on the output end of the mounting plate 1, a mounting column 13 is fixedly provided inside the T-shaped fixing plate 12, there are two telescopic cylinders 11, and the output ends of the two telescopic cylinders 11 are fixedly mounted on the top of the T-shaped fixing plate 12, and the two telescopic cylinders 11 are used to make the T-shaped fixing plate 12 move more smoothly, so that the mounting column 13 drives the vacuum box 14 to move more smoothly, and the vacuum box 14 is fixedly mounted on the right end of the mounting column 13, and the telescopic cylinder 11 drives the vacuum box 14 to move downward or upward through the T-shaped fixing plate 12 and the mounting column 13, so that the vacuum box 14 drives the fixed plate 15 to move to the middle of the side of the carton, thereby avoiding deviation of the force position on the side of the carton and facilitating the fixed transportation of cartons of different heights.

[0023] The carton palletizer clamp is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0024] During use: the connecting frame 2 is fixedly installed on the carton palletizer. When the cartons need to be palletized, the carton palletizer pushes the mounting plate 1 toward the top of the carton through the connecting frame 2, so that the mounting plate 1 pushes the fixed plate 2 21 to contact the top of the carton through the vacuum box 2 20, and then drives the output end through the telescopic cylinder 11 to push the T-shaped fixed plate 12 downward or upward. The T-shaped fixed plate 12 drives the vacuum box 14 downward or upward through the mounting column 13, so that the vacuum box 14 drives the fixed plate 15 to move to the middle of the side of the carton. Then, the output end is driven by the servo motor 5 to drive the rotating screw 6 to rotate, so that the moving screw sleeve 7 moves to the right along the thread direction of the rotating screw 6 surface, so that the moving plate 8 drives the telescopic cylinder 11 to move to the right, and the position of the moving plate 8 is adjusted by the guide sleeve 9 and the guide rail 10. The positioning direction is limited so that the T-shaped fixed plate 12 pushes the vacuum box 14 toward the carton through the mounting column 13, and the vacuum box 14 pushes the fixed plate 15 to contact the side of the carton, and the vacuum pump 16 is started, so that the connecting pipe 18 and the connecting pipe 2 19 respectively extract the air in the vacuum box 14 and the vacuum box 2 20, so that a vacuum is formed inside the vacuum box 14 and the vacuum box 2 20, and the pressure difference between the external environment of the vacuum box 14 and the vacuum box 2 20 is used to make the carton adsorbed on the fixed plate 15 and the fixed plate 2 21. After the palletizer moves the carton to the palletizing position through the clamp, the vacuum pump 16 stops running, so that the pressure in the vacuum box 14 and the vacuum box 2 20 is restored to the pressure box of the external environment, and then the palletizer can remove the clamp from the carton. During this process, there is no need to support the bottom of the carton.

[0025] In summary, the carton palletizer clamp uses a vacuum assembly to simultaneously vacuum the inside of vacuum box 14 and vacuum box 2 20, thereby forming a pressure difference with the external environment and fixing the carton on fixed plate 15 and fixed plate 2 21, thereby applying an adsorption force to the top and sides of the carton, thereby fixing the carton. The carton palletizer can transport and stack the cartons through the clamp, avoiding the situation where the clamping plate is difficult to detach from the carton due to the large friction between the clamping plate and the carton, and avoiding the situation where the clamping plate on one side detaches while the clamping plate on the other side does not detach, thereby avoiding the situation where the cartons are placed crookedly and stacked unevenly, and is used to solve the problems raised in the above background technology.
