Method and device for aligning and separating plate-shaped workpieces provided in a workpiece stack

摘要

Method and device for aligning and separating plate-shaped workpieces (4, 4a, 4b) provided in a workpiece stack (2). The method comprises the following steps: lifting the workpiece stack (2) in a Z direction to a first processing level (N1); Shifting a respective uppermost workpiece (4a) of the workpiece stack (2) on the first processing level (N1) and on the respective workpiece (4b) below it to at least one stop device (16); Aligning at least one workpiece edge (4a.2) of the displaced uppermost workpiece (4a) on the stop device (16); Holding at least a portion of the aligned uppermost workpiece (4a) on the first machining level (N1); and lowering the one located below the uppermost workpiece (4a) to a second machining level (N2), whereby an air gap (34) is created between the uppermost workpiece (4a) and the underlying workpiece (4b), and thereby in turn a perpendicular one to the workpiece surface Adhesion effect is canceled and the top workpiece (4a) is separated from the workpiece stack (2).
