Abstract
An arrangement for separating flat stacked objects is composed of a stacking hopper, the base of which supports the stack and is composed of rolls. The rolls pass through at intervals and roll against the respective bottommost workpiece. The rolls are provided in a traveling series and are driven in a rotating manner. A conveyor belt for transporting material away is arranged below the series of rolls. The respective bottommost workpiece successively peeled off the stack by each roll passage is placed onto the conveyor belt. In sync with the passage of the rolls, suction boxes grip and pull down a lateral edge of the respective bottommost workpiece between two rolls in such a way that the roll that arrives below the stack still supports the stack through the workpiece. The subsequent roll passes between the workpiece and the workpiece located above the previous workpiece and causes a reliable separation of the respective bottommost piece from the stack. In order to transport separated workpieces away such that the lateral edges of these pieces are parallel to the direction of transport of the conveyor belt for conveying material, the stacking hopper is arranged between the upper belt and lower belt of the traveling series of rolls in such a way that the lower belt forms the base which supports the stack in the hopper. The conveyor belt for transporting material away is arranged in parallel with the lower belt of the traveling series of rolls and transports in the direction opposite that of the lower belt of the traveling series of rolls.
