Receptacle feeding system

An article feeder assembly having a pocketed separator and a discharge tube configured to deliver articles to the pocketed separator. Some embodiments include an initial feeder assembly in overlying relation with a track extending from the initial feeder assembly to the discharge tube. Articles are oriented in end-to-end orientation in the initial feeder assembly and delivered to the pocketed separator in vertical end-to-end orientation. As pocketed separator rotates with respect to discharge tube, vertical retention members pass through a tunnel in the discharge tube and rotate articles out of the discharge tube. The discharged articles are secured in pockets delineated by the retention members. Some embodiments use one or more cam mechanisms to properly orient the discharged articles as the pocketed separator rotates. Properly oriented articles are then delivered to an advancing mechanism, such as a conveyor system.
