Rotary object feeder

摘要

The present invention is directed to a rotary object feeder, which feeds objects from a by rotating the objects from a pick-up location to a drop-off location. The object is picked-up by at least one pick-up member having a suction cup. Suction at the suction cup is controlled by a vacuum generator proximate the suction cup. Additionally, a control valve is interconnected to a programmable controller that controls the presence or absence of suction at the suction cup. The controller may be dynamically programmed for flexibly adjusting the pick-up and drop-off locations for objects. The controller may further advance the turn-off position of vacuum at the suction cup, in order to implement a speed compensation system to accurately deliver objects to the drop-off location. The invention is particular well suited for use as a rotary carton feeder.
