It has the advantages of high precision, fast cutting and a wide range of cutting sheet thickness.

[0003] At present, the plate cutting of the cutting machine requires that the whole plate to be cut is placed on the grid of the loading and unloading device, and the chain conveyor of the loading and unloading device transfers the grid to the cutting machine. The chain conveyor in the cutting machine receives the grid and moves it to the specified position, and then the cutting machine cuts the plate on the grid according to the set cutting set program. After cutting, the chain conveyor in the cutting machine sends the grid back to the loading and unloading device, and the cut workpieces and waste are picked one by one by manual or other devices for separation and transportation.

[0004] Since the boards cut by the cutting machine are cut into small pieces in large quantities, it takes a long time to sort them manually, which is labor-intensive and will delay the cutting efficiency of the cutting machine. Although some manufacturers currently use different automated equipment to unload the boards after cutting to improve cutting efficiency and reduce the degree of manual participation, it is still difficult to complete the picking and unloading of individual small pieces of waste at the same time.

The chain conveyor A2 is used to transfer the grille 3 to the chain conveyor B0011 inside the cutting machine 001 or receive the grille 3 from the chain conveyor B0011. The structures of the chain conveyor A2 and the chain conveyor B0011 themselves adopt the existing technology, and the connection setting structure between the chain conveyor A2 and the grille 3 is also the existing technology. The chain conveyor A2, the cutting machine 001 and the chain conveyor B0011 are all controlled by an external controller.

[0032] The loading and unloading device for plate cutting proposed in the utility model also includes a flip frame 4 and a lifting cylinder 5.

One end of the lifting cylinder 5 is hinged to the other side in the length direction of the flip frame 4. The other end of the lifting cylinder 5 is hinged to the base frame 1. The chain conveyor A2 is installed on the flip frame 4. In this embodiment, the lifting cylinder 5 is a commercially available product, and its action is controlled by an external controller. Figure 3 As shown, when the lifting cylinder 5 is in the initial contraction state, the chain conveyor A2, the grid 3 and the turning frame 4 are all kept in a horizontal position; Figure 4 As shown, by controlling the lifting cylinder 5 to extend, the turning frame 4 is driven to turn around the turning shaft 6, and the chain conveyor A2 and the grille 3 turn along with the turning frame 4, so that the waste falls from the grille 3.

[0033] In this embodiment, the length directions of the base frame 1, the flip frame 4, the chain conveyor A2 and the grille 3 are parallel to each other, and the length direction of the base frame 1 is also the length direction of the entire loading and unloading device for plate cutting. One end of the length direction of the base frame 1 faces the location of the cutting machine 001.

[0034] Specifically, if Figure 4 As shown, in this embodiment, a support ear A 401 for hinged connection with one end of the lifting cylinder 5 is protruded on the other side surface in the length direction of the flip frame 4, and a support ear B 102 for hinged connection with the other end of the lifting cylinder 5 is protruded on the other side surface in the length direction of the basic frame 1, so as to facilitate the installation and connection of the lifting cylinder 5.

The blanking box 002 is used to receive the plate waste and the like that falls after the flip frame 4 of the loading and unloading device for plate cutting. In this embodiment, the industrial robot 003 and the horizontal slide 005 are both commercially available products, and the actions are controlled by an external controller. In this embodiment, the end picker 004 adopts the existing technology, such as an electromagnet or a vacuum suction cup structure, and the action is controlled by an external controller.

[0040] Working principle:

[0041] When it is necessary to load the cutting machine 001, the whole plate material to be cut is manually lifted to the grille 3 on the chain conveyor A 2, and the plate is positioned according to the specified requirements. Then the chain conveyor A 2 transfers the grille 3 to the chain conveyor B 0011 inside the cutting machine 001, so that the cutting machine 001 cuts the plate according to the set of drawings issued by the system. During the cutting process, the waste edge material is cut off according to a certain size; after the cutting machine 001 completes the cutting of the plate, when it is necessary to unload the plate material on the grille 3, the chain conveyor B 0011 transfers the grille 3 back to the chain conveyor A 2; the industrial robot 003 can cover the entire range of the grid 3 through the cooperation of the horizontal slide 005. The industrial robot 003 uses the end picker 004 to sort the required cut plates according to the structural shape and size specifications to the corresponding material tray 006; after completing the picking of the required plate parts, the industrial robot 003 drives the end picker 004 to leave from above the grid 3, and each ejecting cylinder 8 extends and drives the ejecting head plate 7 to rise. Each ejecting protrusion of the ejecting head plate 7 passes through the corresponding space of the grid 3, and lifts the material on the grid 3 and leaves the grid 3; the lifting cylinder 5 is controlled to extend, thereby driving the flip frame 4 to flip around the flip shaft 6, and the chain conveyor A2 and the grid 3 are flipped at a certain angle with the flip frame 4, so that the waste falls from the grid 3, and the plate waste and the small blocks that cannot be picked on the grid 3 slide down along the inclined grid 3 into the drop box 002, and then the lifting cylinder 5 and each ejecting cylinder 8 return to their original positions to wait for the next work.
