Abstract
A magazine for conveying cartons to a metering wheel. The magazine has a stack conveyor holding the bulk of the cartons in the magazine and a feed conveyor downstream from the stack conveyor. The two conveyors are separated by an upper inclined stop and lower ramp that keeps the cartons on the stack conveyor from applying pressure to the cartons on the feed conveyor.
Claims8
Apparatus for feeding cartons comprising,
- a frame,
- a feeder mounted on said frame,
- an endless feeder conveyor mounted on said frame and having an upper run whose discharge end lies adjacent said feeder,
- an endless stack conveyor mounted on said frame upstream from said feeder conveyor, said stack conveyor having an upper run that is elevated from said feeder conveyor upper run,
- said conveyors carrying flat folded cartons in a generally vertical attitude and leaning slightly forward,
- a downwardly-inclined ramp between said stack conveyor and said feeder conveyor, said ramp being engageable by the lower edges of said cartons to permit the cartons to slide from said stack conveyor to said feeder conveyor, said ramp creating a gap between cartons on said stack and feeder conveyors,
- said stack conveyor upper run having a discharge end adjacent said feeder conveyor,
- a stop mounted above said stack conveyor discharge end to block forward movement of the cartons on said stack conveyor.

Apparatus for feeding cartons comprising,
- a frame,
- a rotary feeder mounted on said frame,
- an endless feeder conveyor mounted on said frame and having an upper run whose discharge end underlies said rotary feeder,
- means for driving said feeder conveyor,
- an endless stack conveyor mounted on said frame upstream from said feeder conveyor, said stack conveyor having an upper run that is elevated from said feeder conveyor upper run,
- means for driving said stack conveyor,
- said conveyors carrying flat folded cartons in a generally vertical attitude and leaning slightly forward,
- said stack conveyor upper run having a discharge end adjacent said feeder conveyor,
- an inclined rearwardly-facing stop mounted above said stack conveyor discharge end to block forward movement of the cartons on said stack conveyor,
- a forwardly-facing ramp below said inclined stop to guide the lower edges of cartons onto said feeder conveyor.

- said stack conveyor upper run having a discharge end adjacent said feeder conveyor,
- a stop mounted above said stack conveyor discharge end to block forward movement of the cartons on said stack conveyor, and
- means for maintaining a supply of cartons on said ramp to apply pressure to the lower edges of downstream cartons to keep them from sliding rearwardly.
