ABSTRACT:
A device for isolating stacked flat workpieces includes a driven, web-like supporting framework which rotates in a frame. Rotating rolls are supported at equal intervals on a circle concentric to the turning axis of the framework. Each roll is provided with a row of suction boxes. Driving gears of the rolls are rotated, in a direction opposite to the rotation direction of the supporting framework, by a spider gear fixed to the framework. Intermediate gears, through which the spider gear rotates the driving gears, are supported in the supporting framework. A stacking cartridge is placed at the external cylinder defined by the row of suction boxes in such a way that each row of suction boxes of each roll withdraws an exposed workpiece from the cartridge. A transport device which removes an isolated workpiece and further transports the workpiece is placed at the external cylinder. In order to prevent a stack from being set into vibration by a passing roll, a stacking cartridge completely confines the stack.
