CLAIMS

1. A machine for sequentially extracting collapsed sleeve type end loading cartons having oppositely disposed panels from a hopper and positioning them in an opened configuration upon a conveyor, said machine comprising a series of carton transport wheels each bearing suction means for releasable gripping the carton panels, said series of rotating carton transport wheels including a carton extraction wheel mounted adjacent an end of the hopper, a delivery wheel mounted adjacent the conveyor, and an intermediary wheel mounted adjacent said delivery wheel; mearls for rotating said carton extraction wheel; means for rotating said delivery wheel and said intermediary wheel in opposite rotational directions; and suction control means for operating said suction means on each of said wheels in timed relation for the sequential extraction of cartons from the hopper and for the relay of the cartons through the series of transport wheels, and for the delivery of the cartons to the conveyor in an at-least partially opened configuration by the maintenance of suction of said intermediary wheel and delivery wheel suction means in timed coincidence to cause the oppositely disposed panels of cartons being relayed from said intermediary wheel to said delivery wheel to be spread apart.

2. The machine of claim 1 wherein said intermediary wheel is mounted adjacent said extraction wheel.

3. In a packing machine of the type having a hopper, an endless conveyor and means for inserting goods into end loading cartons carried on the conveyor, the improvement comprising a chain of rotatably driven suction means extending in tandem from said hopper to said conveyor, and suction control means for activating and deactivating said suction means in timed relation for extracting cartons in a collapsed configuration sequentially from said hopper and for delivering them onto said conveyor in an open configuration .

4. The machine of claim 3 wherein said chain of suction means includes a carton extraction wheel mounted adjacent an end of the hopper, a delivery wheel mounted adjacent the conveyor, an intermediary wheel mounted adjacent said delivery wheel, drive means for rotating each of said wheels, and outwardly extending suction cups mounted to each of said wheels.

5. The machine of claim 4 wherein said intermediary wheel is mounted adjacent said extraction wheel.

6. A machine for sequentially extracting and opening collapsed sleeve type end loading cartons having oppositely disposed panels, said machine comprising:
a hopper for holding a stack of cartons;
a carton extraction wheel mounted adjacent an end of said hopper;
a carton delivery wheel;
an intermediate carton transport wheel mounted adjacent said delivery wheel;
means for rotating said extraction wheel;
means for rotating said delivery wheel and said intermediate wheel in opposite rotational directions;
an endless conveyor mounted adjacent said delivery wheel ;
suction means mounted to each of said wheels for releasably gripping the cartons; and
suction control means for operating said suction means in timed relation for the sequential extraction of cartons from said hopper, for the relay of the cartons through the wheels, and for the delivery of the cartons to the conveyor in an at-least partially opened configuration by the simultaneous maintenance of suction on said intermediary wheel suction means in gripping engagement with one of the oppositely disposed panels of a carton and on said delivery wheel suction means in gripping engagement with the other panel of the carton to cause the oppositely disposed panels of cartons being relayed from said intermediary wheel to said delivery wheel to be spread apart.

7. The machine of claim 6 wherein said hopper is oriented substantially horizontal and has drive means for driving the cartons towards said extraction wheel .

8. The machine of claim 7 wherein said drive means includes at least one drive screw.

9. The machine of claim 6 wherein said intermediary wheel is mounted adjacent said extraction wheel.

10. The machine of claim 6 wherein said delivery wheel suction means includes suction cups extending outwardly from said delivery wheel and adjusting means for varying the circumferential spacing between each said suction cups so as to grip cartons of various sizes.
