ABSTRACT:
A carton transfer assembly having a rotary feeder that rotates a series of selectors about a transfer path between a carton feeder and a transport conveyor. The selectors each include vacuum engagement members adapted to engage a selected carton to remove the selected carton from the carton feeder and carry the carton toward a transport conveyor as the rotary feeder rotates the selectors about the transfer path. Each selector further includes stingers that are operated off of the vacuum applied to the cartons by the vacuum engagement members to move the stingers between extended and retracted positions. As the vacuum is applied to the stingers, the stingers are retracted. When the vacuum is disengaged, the stingers move to an extended position to engage and spread apart the panels of the cartons to open the cartons prior to the deposit of the cartons within the carton pockets of the transport conveyor.
