Abstract
Abstract A transfer device for seriately receiving from a forming machine frustoconical paper bucket bodies, nestably accumulating them in a horizontal column in a cylindrical front section of a rotatable drum, loosening the nested bucket bodies from each other in an enlarged cylindrical rear section of the drum, randomly separating the column of bucket bodies into small groups, intermittently conveying successive groups axially away from said drum to a lateral conveyor, conveying the groups laterally to a remote processing machine and adavancing said groups axially into said machine in a direction opposite from the first axial direction.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
78 words
A bucket body transfer device comprising: a horizontally disposed rotatable drum having an open-ended accumulator section for receiving frustoconical bucket bodies and nestably accumulating them in a column, said accumulator section having a cylindrical inner surface, a separator section integrally connected to said accumulator section, said separator section having an enlarged openended cylindrical inner surface coaxially aligned with said accumulator surface, means for rotating said drum, and an offloading conveyor at the exit end of said separator section.
Claim 2
Dependent Claim
78 words
A bucket body transfer device comprising: a horizontally disposed rotatable drum having an open-ended accumulator section for receiving frustoconical bucket bodies and nestably accumulating them in a column, said accumulator section having a cylindrical inner surface, a separator section integrally connected to said accumulator section, said separator section having an enlarged openended cylindrical inner surface coaxially aligned with said accumulator surface, means for rotating said drum, and an offloading conveyor at the exit end of said separator section.
Claim 3
Dependent Claim
47 words
A transfer device according to claim 1 wherein the internal diameter of said accumulator section is larger than the maximum diameter of said bucket bodies and the internal diameter of said separator section is between 25 percent and 35 percent greater than that of said accumulator section.
Claim 4
Dependent Claim
36 words
A transfer device according to claim 1 wherein said offloading conveyor transports said bucket bodies in an axial direction away from said drum is movably mounted for cycling between a conveying mode and a nonconveying mode.
Claim 5
Dependent Claim
44 words
A transfer device according to claim 3 wherein said offloading conveyor includes a separate conveyor extension at its downstream end driven by a common drive means such that the travel speed of the conveyor extension is greater than that of the upstream conveyor section.
Claim 6
Dependent Claim
43 words
A transfer device according to claim 4 wherein said separate conveyor extension is a twin belt conveyor mounted on front and rear sets of dual sheaves such that the top runs of the belts are horizontally disposed and converge in a rearward direction.
Claim 7
Dependent Claim
46 words
A transfer device according to claim 5 wherein said front set of dual sheaves has a pair of resilient rings mounted on the inside edges thereof, said rings having a greater diameter than said sheaves so as to extend beyond the outer surfaces of said belts.
Claim 8
Dependent Claim
65 words
A transfer device according to claim 1 wherein said offloading conveyor transports said bucket bodies in a first axial direction and further includes a lateral conveyor at the downstream end of said offloading conveyor, and a second axial conveyor for receiving bucket bodies from the lateral conveyor and transporting them in an axial direction opposite from said first axial direction to a bucket finishing machine.
