ABSTRACT:
The apparatus for forming separate piles of equal-numbers of workpieces, especially can covers, from a stack moving longitudinally in a feed trough is equipped with an electronic counter and controller with a sensor responding to the edge of the workpiece which operates without contact with the workpiece and with a feed device which is shiftable into a clamped and a released position engaged on the stack upstream of the sensor in the feed direction. It is drivable in the clamped position with at least two feed speads. Moreover a separating mechanism is provided with a separating wedge movable to-and-fro transverse to the stack to form a separating gap in the edge region between the adjacent workpieces of the pile and the stack together with two separating knives guidable into the separating gap which are connected with a drive acting in the longitudinal direction of the stack. The new apparatus can be mounted at each position along the conveying trough without interruption of or blocking the trough. A very exact counting with larger tolerances for the cover edges is possible. it is easy to adjust the apparatus to different cover sizes.
