Description

Technical Field

[0001] The utility model relates to the technical field of palletizing and stacking machines, in particular to a palletizing and stacking machine. Background Art

[0002] A palletizer automatically stacks cartons that have been packed into containers in a certain arrangement on flat surfaces such as pallets and stacking boards. It can stack multiple layers and then push them out to facilitate transportation by forklifts and other means of transport to warehouses for storage. Palletizers are commonly used auxiliary equipment for material placement in modern industrial production. Palletizers are also used in the process of plate palletizing. When the plates are completed, they are stacked and placed in a preset arrangement through a palletizer. After each layer of plates is placed, the position is automatically adjusted to facilitate the placement of the next layer of plates.

[0003] For example, a palletizer for stacking plates disclosed in the utility model with authorization announcement number CN221070101U transports plates by setting a conveyor belt. By controlling the hydraulic cylinder to drive the lifting shaft to move upward, the plate height can be gradually increased during the stacking process, thereby realizing the stacking of plates. By setting multiple guide rollers, the side of the plate can be limited. By setting a buffer spring, the connecting roller can maintain traction on the conveyor belt under the limiting action of the support rod, thereby keeping the conveyor belt taut.

[0004] This prior art also has the following problems when used:

[0005] The device continuously increases the conveying height of the plate by lifting the lifting shaft. However, as the lifting shaft is lifted, when the angle between the plate and the horizontal plane is too large, the plate on the conveyor belt is easily affected by its own gravity and slides downward in the direction opposite to the conveying direction. When the angle between the plate on the conveyor belt of this device and the horizontal plane is large, the plate needs to move downward to separate from the conveyor belt and be stacked with other plates. The distance it needs to move downward is large, which makes the plate susceptible to damage. Utility Model Content

[0027] like Figure 1-Figure 4As shown, a storage assembly is provided above the bottom plate 1, and the storage assembly consists of a storage box 14, a handle 15, a through slot 16, a mounting box 17 and a roller 18. A storage box 14 is provided on the top surface of the lifting plate 13. One side of the storage box 14 is open, and symmetrical handles 15 are fixedly provided on the front and back sides of the storage box 14.

When the stacking box 14 is full of plates, the first servo motor 4 and the second servo motor 7 are turned off, and the handle 15 is lifted or the second servo motor 7 is controlled to drive the first bevel gear 8 to rotate in the opposite direction, so that the storage box 14 can be moved upward and disengaged from the guide rod 11, and the storage box 14 is placed on the ground. Pushing the handle 15 and cooperating with the roller 18 can transport the plates in the storage box 14 to the designated position.

[0028] Specific working principle:

[0029] When the device is in use, align the through slot 16 with the guide rod 11 so that the storage box 14 is placed on the top surface of the lifting plate 13, and control the first servo motor 4 to drive the active roller 19 to rotate at a uniform speed, which can drive the conveyor belt 5 to rotate at a uniform speed. The rotation of the conveyor belt 5 drives the driven roller 20 to rotate, and plates of the same thickness are placed equidistantly on the top surface of the conveyor belt 5. The active roller 19 rotates at a uniform speed to drive the conveyor belt 5 to rotate at a uniform speed, so that the plates can be transported at a uniform speed. When the plates begin to separate from the conveyor belt 5 and rotate downward, they will contact the inclined plate 6 and slide downward along the top surface of the inclined plate 6. When the plates slide downward along the inclined plate 6, they just enter the interior of the storage box 14 and contact the bottom surface of the storage box 14, so that the plates slide completely into the bottom surface of the storage box 14. Control the second servo motor 7 to drive the first bevel gear 8 to rotate at a uniform speed. The rotation of the first bevel gear 8 drives the second bevel gear 9 to rotate. The rotation of the second bevel gear 9 drives the threaded rod 10 to rotate, and the rotation of the threaded rod 10 cooperates with the guide rod 11 The lifting block 12 and the lifting plate 13 move downward at a uniform speed at the same time. The movement of the lifting plate 13 drives the storage box 14 and the plates inside the storage box 14 to move downward at a uniform speed. When the lifting plate 13 moves downward a distance equal to the thickness of the plates, the next plate slides downward along the top surface of the inclined plate 6 and just contacts the top surface of the plates inside the storage box 14. The plate slides along the top surface of the lower plate and is stacked on the top surface of the lower plate. The lifting plate 13 continues to move downward so that the plates can be stacked in sequence inside the storage box 14, thereby realizing palletizing of the plates. When the storage box 14 is full of plates, the first servo motor 4 and the second servo motor 7 are turned off, and the handle 15 is lifted or the second servo motor 7 is controlled to drive the first bevel gear 8 to rotate in the opposite direction to make the storage box 14 move upward and disengage from the guide rod 11, and the storage box 14 is placed on the ground. Pushing the handle 15 in conjunction with the roller 18 can transport the plates in the storage box 14 to the designated position.
