A conveyor for moving objects having driven rollers which slip with respect to the drive shafts extending therethrough. Each drive shaft has a plurality of side-by-side rollers mounted thereon. A pulley is mounted to the end of each drive shaft to receive a belt which is in driving engagement with a main shaft. The main shaft is connected by belts and pulleys to a motor. The rollers may be arranged in different groups having different rotating speeds with an arrangement of rollers provided for moving objects around a corner. A movable roller pan mounted in a case packer is disclosed having the subject rollers.

A conveyor for moving objects in multiple adjacent rows comprising: a frame; dividing means mounted on said frame defining a plurality of separate passageways each of which receives one of said rows of moving objects; a plurality of cylindrical drive shafts rotatably mounted on said frame and each having an outer surface with an outside diameter; a plurality of cylindrical rollers positioned in said passageways and mounted on each of said drive shafts in side-by-side relation, said rollers having cylindrical interior bearing surfaces of inside diameters enclosing said shafts, at least a portion of each of said interior surfaces contacting said outer surfaces whereby rotation of said shafts imparts rotation to said rollers, said inside diameters being greater than said outside diameters allowing said rollers in one of said passageways when exteriorly stopped to be stationary while said shafts rotate and said rollers in other passageways rotate; all of the side-by-side rollers on each respective drive shaft being spaced apart from the side-by-side rollers on the other drive shafts, said spacing being accomplished by making the distance between the axes of adjacent drive shafts greater than the sum of the radius of any roller on one of said adjacent drive shafts and the radius of the roller opposite thereto on the other of said adjacent drive shafts; said rollers projecting upwardly and being unobstructed to define a discontinuous supporting surface area for the moving objects, said discontinuous surface area extending other than vertically whereby gravity can hold the objects against said discontinuous surface area; a motor for causing said drive shafts to rotate; and, means connecting said drive shafts to an output of said motor.
