Conveyor for sheet-shaped thin plate and method of conveying same

Abstract

A conveyor for guiding and conveying a plurality of sheet-shaped thin plates in rows arranged side by side to a welding position at which ends of the adjacent thin plates are butted and welded to each other, includes a plurality of conveying paths, which are adjacent to each other, having different conveying surfaces which are placed on a same horizontal plane, and a guide unit disposed between the adjacent two conveying paths for guiding the thin plates on one of the conveying paths with respect to another one thereof toward the welding position. Each of the conveying paths is composed of a plurality conveying rollers, and the guide unit includes guide rollers each having a guide surface for guiding the thin plate on the one of the conveying paths in a state that the thin plate on the one conveying path is partially depressed with respect to the another one of the conveying path.

Description

technical field [0001] The invention relates to a conveyor and a method for conveying sheet-shaped sheets, in particular adjoining and welded to each other. Background technique [0002] For example, in the case where steel plates having different materials and thicknesses are used to form, for example, adjacent parts or parts of a vehicle body, two or more previously cut into precise Rectangular-shaped sheet-like sheets (steel plates) are welded together to form a tailor-made blank material. [0003] As a method of welding sheet-like thin plates to form a custom-made blank material, there is provided a method in which a plurality of sheet-like thin plates are fixed in a state where their end surfaces abut each other with no gap therebetween, by A plurality of sheet-like thin plates are welded using a welding machine that is movable along the joining portion. There is also provided a method in which a plurality of sheet-like thin plates are moved in a state in which end su...

Problems solved by technology

Thus, resistance is generated when deforming the thin plate into a corrugated shape, and this adversely affects the conveying operation, which may cause concerns such as the conveying speed becoming unstable

[0012] In addition, there is also the disadvantageous possibility of increasing the contact area between the guide surface of the guide roller and the thick plate, increasing the transmission resistance due to the sliding contact therebetween, and thus increasing the wear

In addition, the guide surfaces of the guide rollers are chamfered, which is necessary to avoid a bite between the guide surfaces of the guide rollers and the thick plate, which could cause deformation of the thin plate to increase by the amount of chamfering, worsens flatness of adjoining surfaces and worsens adhesion to thick plates
