ABSTRACT:
An accumulator is formed alongside the main feed portion of a vibratory object feeder having a vibrated base covered with inclined pile material, and the accumulator is formed by arranging the pile in different bristle inclination directions. A removal portion of the accumulator receives objects crowded out of the feed portion, and a re-entry portion of the accumulator moves the crowded-out objects back into the feeder portion. The bristle inclination directions of the pile material in the accumulator cooperate to move the crowded-out objects in a generally arcuate swirl that re-enters the objects into the feed path as soon as space is available. A small number of crowded-out objects form a small diameter swirl, and the swirl diameter increases with increase in the number of crowded-out objects to accumulate as many objects as desired. Such an arrangement also re-enters the crowded-out objects into the main feed path as soon as space is available so there is no delay in waiting for the last of the crowded-out objects to arrive at the output.
