Abstract
The device according to the invention for ejecting sheet metal blanks from a processing station or for any transport of such sheet metal blanks has ejector dogs mounted on a transport conveyor, which bump the trailing edge (trailing in the ejection direction (A)) to eject the blanks. These ejector dogs are arranged so that upon impact on the blank edge they are shifted and/or tilted in a damped manner, and with absorption of energy, with respect to the transport conveyor, in the opposite direction to the ejection direction, thus reducing the forces acting on the edge of the blank. As transport conveyor, the preferred embodiment has a toothed belt which is elastically deformed and deflected from its path upon impact of the dog on the blank edge, so that the belt itself acts as damper and as return spring for the dog.
