Abstract
A conveyor system having an infeed conveyor section, an outfeed conveyor section, and a working conveyor section positioned in between and in line with the infeed and outfeed conveyor sections. The working conveyor section includes a base and a frame which is movably mounted relative to the base between a lower position and a raised position. In order to move the frame between its lower and raised position, a driver is rotatably mounted about a substantially horizontal axis to the base while an elongated drive link has one end pivotally connected to the frame and its other end pivotally connected to the driver at a position radially spaced from its axis. A drive mechanism selectively pivots the driver between first and second rotational positions which are spaced substantially 180 degrees from each other. In doing so, the coaction between the driver and the drive link moves the frame between its raised and lowered position.
