Description

Technical Field

[0001] This invention relates to the field of material stacking technology in mechanical manufacturing processes, specifically to an automatic stacking device for flat materials at the end of a stamping line conveyor belt. Background Technology

[0002] In the stamping manufacturing process of automotive parts, the industrially processed materials are continuously fed backwards via conveyor belts. After manual collection and stacking, they are sent to the subsequent process flow. However, the manual collection and stacking process requires the participation of multiple operators, which results in low efficiency and certain safety hazards. In addition, most of the existing unloading and stacking devices are of fixed size and are only suitable for collecting and stacking specific materials. Their application range is very limited, and the devices are relatively large, requiring a large site.

[0003] For example, CN115488256A discloses a stacking mechanism for sheet metal after shearing by a shearing machine, which belongs to the field of mechanical manufacturing technology. The shearing machine includes a conveyor and a sheet metal shelf. A sheet metal sensing unit is fixedly connected to the left end of the output machine and used to sense the passing of the sheet metal. A sheet metal shelf conveying unit is provided on the right end of the sheet metal shelf to facilitate the conveying of the sheet metal to the sheet metal shelf. A stacking unit is provided on the sheet metal shelf and connected to it for stacking and arranging the sheet metal.

[0004] The aforementioned published documents do not allow for adjustment of the dropping angle, which can easily damage the sheet metal. The stacking accuracy is not high enough, and it can only stack materials of a single size. Therefore, it is necessary to propose an automatic stacking device for flat materials at the end of the stamping line conveyor belt, which can automatically drop and stack materials of different sizes. Summary of the Invention

[0005] To address the problems of existing technologies, this invention provides an automatic stacking device for flat materials at the end of a stamping line conveyor belt. A four-bar linkage driven by an electric cylinder in the pitch assembly adjusts the pitch angle of the pallet, controlling the material drop angle. A centering assembly adjusts the unfolded width of the pallet, while side stops position the material during its descent. A telescopic assembly adjusts the telescopic distance of the moving slide rail, controlling the material's falling position. Furthermore, a limiting assembly blocks and limits the material, while a cylinder extension allows the material to fall freely into a collection box. A collection assembly automatically repositions the collection box, continuously collecting the material.

[0033] The following describes in further detail an automatic stacking device for flat materials at the end of a stamping line conveyor belt according to the present invention, with reference to specific embodiments. The operation process of the automatic stacking device for flat materials at the end of a stamping line conveyor belt according to the present invention is as follows:

[0034] First, the electric cylinder 22 is controlled by the electric control box 6. The telescopic rod of the electric cylinder 22 pushes the connecting shaft 23, and the pitch angle of the pallet 35 is adjusted by the four-bar linkage. The rope drive motor 41 drives the rope collecting wheel 44 to rotate, and the length of the rope 45 is adjusted to move the sliding rail 46 to determine the position of the material stacking. The horizontal electric cylinder 13 drives the collecting box 16 to reach the corresponding position.

[0035] Then, the user rotates the handwheel 33 according to the material size, and the torque is transmitted through the lead screw 31 connected to it to make the pallets 35 on both sides open and close synchronously to adapt to the material size. With the help of the stop blocks 36 on both sides, the size of the material is adapted and the position is restricted. The industrial conveyor belt is turned on, and the material is continuously transported to the end of the conveyor belt. As the conveyor belt moves, the material falls onto the pallet 35 and slides down under the action of gravity. After passing the stop blocks 36 on both sides, the material is passively straightened and slides into the limiting component 5. Under the limiting of the baffles 55 on both sides and the buffer of the rubber pads 57, it stops at the position of the limiting component 5, at which time it is located at the material dropping position.

[0036] Finally, cylinder 53 extends, and the two L-shaped trays 54 move in opposite directions, no longer lifting the material. The material falls freely into collection box 16. When collection box 16 is full, horizontal electric cylinder 13 pushes slide table 14 to move and switch to another collection box 16 to continue the collection task. Before another collection box 16 is full, the operator needs to replace collection box 16 to ensure continuous collection of materials.

[0037] This invention relates to an automatic material stacking device for flat plates at the end of a stamping line conveyor belt. The device uses a four-bar linkage driven by an electric cylinder 22 in the pitch assembly 2 to adjust the pitch angle of the pallet 35, thus controlling the material drop angle. The centering assembly 3 adjusts the unfolded width of the pallet 35, and the side blocks 36 position the material during its descent. The telescopic assembly 4 adjusts the telescopic distance of the moving slide rail 46 to control the material's falling position. The limiting assembly 5 blocks and limits the material, while the extension of the cylinder 53 allows the material to fall freely into the collection box 16. The collection assembly 1 automatically repositions the collection box 16 to continuously collect the material.

[0038] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
