Abstract
An unscrambler conveyor including a frame, a plurality of tapered rollers rotatably supported by the frame for unscrambling packages, and means for driving the rollers. Each of the rollers has a longitudinal axis and a polyurethane body that extends along the longitudinal axis to form a tapered outer surface. The tapered outer surfaces of the rollers define a conveying surface and have variations in concentricity of less than 0.01 inches.
Claims54
An unscrambler conveyor assembly comprising:
- a frame;
- a plurality of tapered rollers rotatably supported by said frame for unscrambling packages;
- and
- means for driving said rollers, each of said rollers having a longitudinal extent extending along a longitudinal axis from a proximate first end to a distal second end, each of said rollers having a polyurethane body extending along said longitudinal axis substantially across said longitudinal extent and forming a tapered outer surface, said tapered outer surfaces of said rollers defining a conveying surface and having variations in concentricity of less than 0.01 inch.
An unscrambler conveyor assembly comprising:
- a frame;
- a plurality of tapered rollers rotatably supported by said frame, each of said rollers having a longitudinal axis and a longitudinal extend extending from a proximal first end to a distal second end, each of said rollers including a polyurethane body extending along said longitudinal axis from adjacent said distal end to adjacent said proximal end and forming a tapered outer surface, said tapered outer surfaces defining a conveying surface;
- and
- means for driving said rollers, when operated said means driving said rollers at a speed of at least 900 rpm.
An unscrambler conveyor assembly comprising:
- a frame;
- a plurality of tapered rollers rotatably supported by said frame, each of said rollers having a conveying surface having a conveying width between a proximal first end to a distal second end, and each of said rollers having a polyurethane body forming a tapered outer surface extending across the full width of said conveying surface, said rollers having a high side and a low side, packages being unscrambled by said rollers moving toward said low side when unscrambled;
- and
- means for driving said rollers at said high side to thereby minimize interference between said means and the packages being unscrambled.
An unscrambler conveyor assembly comprising:
- a frame;
- a plurality of tapered rollers rotatably supported by said frame, each of said tapered rollers having a longitudinal axis and defining a substantially continuous tapered conveying surface, each of said rollers including a base roller having a monolithic polyurethane body extending along said longitudinal axis to form said tapered conveying surface;
- and
- means for driving said tapered rollers.
An unscrambler conveyor assembly comprising:
- a frame;
- a plurality of tapered rollers rotatably supported by said frame, each of said tapered rollers having a longitudinal axis and comprising a straight base roller with an outer surface with terminal ends and a monolithic polyurethane body extending along said longitudinal axis from adjacent one of said terminal ends to adjacent to another of said terminal ends, each of said polyurethane bodies having a thickness, said thicknesses increasing across said longitudinal axes at a generally uniform rate to form continuous tapered outer surfaces;
- and
- means for driving said tapered rollers.
