Abstract
A station for aligning a stack or packet of sheet metal or plate bars to be transported to and unstacked at an unstacking station prior to being pressed or processed at a pressing or processing station. The alignment station includes a transporting carriage equipped with a chain conveyor system and a lifting and turning device as well as a stationary measuring system. The measuring system serves to detect the angular position of the sheet metal packet disposed on the transporting carriage and is composed of a rotatably mounted measuring ruler which is placed against the sheet metal packet by means of a pneumatic cylinder. The angular position is measured by way of an absolute value sensor installed at the pivot point of the measuring ruler and is compared with the desired value stored in a control system.
