Problems solved by technology

Its shortcoming is that the surface of metal thin plates such as cold-rolled steel plates and stainless steel plates is flat. After the plates are stacked, the self-weight of the plates will cause the air between the plates to be discharged, causing two or more plates to be adsorbed together. , because the oil stain on the metal plate enhances the adsorption force between the plates, so that the plates stick together and are not easy to be separated
But this device still can not solve the absorption problem of multi-layer plate well, especially for thin plate, because the thin plate is relatively soft, the plate adsorbed on the lower side of the upper plate will be lifted simultaneously with the lifting of a corner of the plate, resulting in two layers or More than two layers of plates still cannot be separated

Embodiment 1

[0027] Such as Figure 1-5 As shown, it is a plate automatic feeding device for preventing multi-layer plates from being picked up. It includes a suction cup bracket 4, and a number of suction cups are installed in an array under the suction cup bracket 4. The suction cups include a fixed suction cup 6a and a movable suction cup 6b. 5 is connected to the lower side of the suction cup bracket 4; the movable suction cup 6b is correspondingly provided with one at a corner of the plate 7, the movable suction cup 6b is connected to the lower end of the swing rod 8, and the lower side of the suction cup bracket 4 is correspondingly provided with a connecting block 1 with the swing rod 8, and connected A cylinder 3 is arranged on the side of the block 1, the piston rod extension end of the cylinder 3 is connected with a cylinder joint 2, the middle part of the swing rod 8 is hinged with the connecting block 1 through the lower pin 9, the upper part of the swing rod 8 is provided with ...

Embodiment 2

[0035] Such as Figure 6 As shown, it is another automatic plate feeding device that prevents the multi-layer plate from being picked up. The difference between it and Embodiment 1 is that the movable suction cup 6b is provided with two or more along one side of the plate, and the corresponding cylinder The axis of 3 is set horizontally, and the 3 axes of adjacent cylinders are set at an angle of 2~5°. Figure 6 Among them, the included angles between cylinder axes M1 and M2, M2 and M3, M3 and M4, M4 and M5 are 2~5°.

[0036] When the suction cup grabs the plate 7, due to the inconsistent swing of the adjacent swing rods 8, not only the plate itself is bent and deformed during the bending process of the plate 7, but also the adjacent swing rod 8 also drives the plate 7 to be partially twisted, and the axis of the adjacent cylinder 3 is in the shape of The angle setting is 2~5°, so that such distortion can obviously promote the delamination of the plate.

Embodiment 3

[0038] Such as Figure 7 As shown, it is the third type of sheet material automatic feeding device that prevents multi-layer sheet materials from being picked up. It is different from Embodiment 1 in that the movable suction cup 6b is arranged at the diagonal. The boards 7 can be layered from two opposite corners. As long as the upper and lower boards 7 are separated at any corner, the boards can be layered smoothly and the boards can be prevented from sticking together by adsorption.

Abstract

The invention discloses an automatic sheet material feeding apparatus and feeding method preventing absorbing multi-layered sheet material in the field of sheet material machining. In the apparatus, a fixing suction disc is connected to a lower side of a suction disc rack by a fixing rod; at least a movable suction disc is arranged on a corner of the sheet material; the movable suction disc is connected to the lower end of a swinging rod; a connection block is arranged in a position where the lower side of the suction disc rack is corresponding to the swinging rod; an air cylinder is arranged on the side surface of the connection block; an extending end of a piston rod of the air cylinder is provided with an air cylinder joint; the middle of the swinging rod is hinged with the connection block via a lower pin roll; the upper part of the swinging rod is provided with a waist-shaped groove; the end part of the air cylinder joint is provided with an upper pin roll; and the upper pin roll is inserted into the waist-shaped groove. During the work, after the sheet material is absorbed by the fixing suction disc and the movable suction disc at the same time, corners of the sheet material are bent when the swinging rod is driven by the air cylinder to swing, so sheet material absorbed together can slide relative to each other and a gap is formed; and sheet material are layered. The automatic sheet material feeding apparatus can be applied to various sheet material machining beds.

Description

technical field [0001] The invention relates to a plate processing machine tool, in particular to a feeding device of the plate processing machine tool. Background technique [0002] In the prior art, there is a feeding device used in conjunction with a sheet metal processing machine tool. Its structure mainly includes a suction cup bracket connected to a servo motion mechanism. A number of suction cups are installed on the lower side of the suction cup bracket through a fixed rod. The suction cups are arranged in an array. The device picks up the plate through the suction cup, and then sends the plate to the machine table for processing through the servo motion mechanism. Its shortcoming is that the surface of metal thin plates such as cold-rolled steel plates and stainless steel plates is flat. After the plates are stacked, the self-weight of the plates will cause the air between the plates to be discharged, causing two or more plates to be adsorbed together. , because th...
