Abstract
Abstract In carton feeding apparatus, a rotary member having a blade which passes behind a leading carton in a group of vertically-oriented cartons to separate the leading carton from the adjacent carton. A lockout member is pivotally mounted on the rotary member and is adapted to be moved in a generally axial direction toward the incoming cartons to block the cartons from engagement by the blade.

A rotary feeder for sheets such as flat folded cartons comprising, a hub, a blade mounted on said hub to pass behind a leading sheet to separate it from the adjacent sheet, a lockout element movably mounted on said hub, said lockout element, when extended axially, projects beyond said blade, thereby engaging a leading sheet and holding it out of engagement by said blade.
Claim 3
Dependent Claim
130 words
In a cartoner having a product bucket conveyor, and an erected carton conveyor running alongside said product bucket conveyor, carton feeding apparatus comprising, an infeed conveyor for carrying cartons in a generally vertical orientation, a rotary feeder above the downstream end of said conveyor, said rotary feeder comprising, a housing, a rotary hub mounted on said housing for rotation about an axis generally parallel to the direction of movement of said conveyor, a blade projecting from said hub and adapted to pass behind a leading carton to separate it from the adjacent carton, a lockout member mounted for generally axial movement on said hub, and means for moving said lockout member in an upstream direction when a product bucket is empty to force a leading carton away from said blade.
Claim 4
Dependent Claim
130 words
In a cartoner having a product bucket conveyor, and an erected carton conveyor running alongside said product bucket conveyor, carton feeding apparatus comprising, an infeed conveyor for carrying cartons in a generally vertical orientation, a rotary feeder above the downstream end of said conveyor, said rotary feeder comprising, a housing, a rotary hub mounted on said housing for rotation about an axis generally parallel to the direction of movement of said conveyor, a blade projecting from said hub and adapted to pass behind a leading carton to separate it from the adjacent carton, a lockout member mounted for generally axial movement on said hub, and means for moving said lockout member in an upstream direction when a product bucket is empty to force a leading carton away from said blade.
Claim 5
Dependent Claim
23 words
Carton feeding apparatus as in claim 2 in which said lockout member is arcuate and is pivoted on said hub adjacent said blade.
Claim 6
Dependent Claim
