ABSTRACT:
A loader for an automatic packaging machine received an inflow of product subject to a randomly variable product delivery. The loader delivers an outflow of product at a defined rate and in a predetermined pattern despite the variations of the inflow. A buffer storage device stores an adjustable amount of product between the inflow and the defined outflow in order to compensate for the random variables. The buffer storage device is a link chain trained over three principal sprocket wheels arranged in a triangular pattern with the wheel at an apex of the triangle being in a fixed position. The portion of the link chain which forms the base of the triangle provides the buffer storage. The product output is taken from approximately a midpoint on the base of the triangle. The two sprocket wheels at the base angles of the triangle are movable so that the base of the triangle may move in one direction to hold more product in buffer storage or may move in an opposite direction to deliver product which is taken from the buffer storage.
