Workpiece positioning device for a processing center, processing center, and method

A workpiece positioning device for a processing center (1), in particular a horizontal processing center, wherein workpieces (12) mounted on a workpiece palette are processed in the processing center (1), with a deposit place (17) that comprises a horizontal deposit surface (18) for a workpiece palette (19), and a pivot bearing (44) that is disposed to take up the workpiece palette (19) on a first edge (41) thereof in a rotatable manner, and with a pivoting device (53) for transferring a workpiece palette (19) from a horizontal position into a vertical position and vice versa, wherein the pivoting device (53) is disposed to grip a workpiece palette (19) on another, second edge (42) and, by simultaneously moving a horizontal and a vertical linear axle (23, 24), to pivot the second edge (42) of the workpiece palette (19) on a circular path (52) around the pivot bearing (44) in order to deposit the workpiece palette (19) in its horizontal position on the deposit place (17) or move it into a vertical position, and wherein the workpiece positioning device (28) is configured to lift the workpiece palette (19) in vertical direction out of the pivot bearing (44) of the deposit place (17) and lower the workpiece palette (19) in vertical direction onto the pivot bearing (44) of the deposit place (17), respectively, using the vertical linear axle (24) while the workpiece palette (19) is in the vertical position and to transport the workpiece palette (19) in horizontal direction using the horizontal linear axle (23) while the workpiece palette (19) is in the vertical position.
