Abstract
An apparatus for controlling the travel of articles along a conveyor track. The apparatus includes a frame (14) positioned relative to the conveyor track (11), and having a downstream end and an upstream end. A first pair of gates (20) extends from the downstream end of the frame (14) into the travel path of the article. The first pair of gates (20) rotates synchronously between a closed position and an open position. A second pair of gates (21) extends from the upstream end of the frame (14) into the travel path of the article. The second pair of gates (21) likewise rotates synchronously between an open position and a closed position. A drive train, including sprockets (30, 31, 36 and 42) and chain (43) simultaneously rotates the first pair (20) and the second pair (21) of gates so that when one of the pairs of gates is in a closed position the other of the pairs of gates is in an open position.
