ABSTRACT:
An object accumulator and feeder uses a relatively long path divided into a series of independently operable sections. The upper surface of the path is covered with a pile material having bristles with tips supporting the objects and inclined toward a direction of feed, and sections of the path are vibrated to vibrate the bristles against the objects to feed the objects through the sections. A sensor is arranged along the path in each section, and the sensors have one output when an object is present in the sensing region and another output when no object is present in the sensing region. Timers respond to the two-state outputs from the sensors and are in circuit with vibrators for switching vibrators on and off to accumulate the objects by successively filling up the sections from the output end toward the input end of the device, to feed the objects out on demand, and to shut off selected vibrators for intervals during which the vibrators are not needed for advancing the objects.
