Abstract
An apparatus for separating and sequentially conveying articles from an article stack includes an article accumulator in which the article stack is formed, a wheel, and a plurality of article pushers mounted on the wheel. Each article pusher has an article pushing face for pushing the article out of the article accumulator and is movable relative to the wheel into a first and a second position. In the first position the article pushing face is sufficiently close to the accumulator to abut and carry an article as the pusher passes by the accumulator and in the second position the article pushing face is sufficiently remote from the accumulator to move past the stack without abutting an article as the article pusher passes by the accumulator. Further, a control device moves selected article pushers into the second position prior to reaching the accumulator. A device resets the article pushers into the first position after having passed the accumulator. There is further provided an article ejecting device for moving each article away from the wheel after the article has been carried from the accumulator.
