ABSTRACT:
A live roller conveyor having a supporting frame and a plurality of load supporting transport or carrier rollers rotatably supported from the frame and a plurality of drive wheels in frictional driving contact with the rollers for frictionally driving the rollers. Certain of the drive wheels are powered from a power source and all of the drive wheels are spring biased toward the rollers. In one embodiment, the drive source is a line shaft having a friction drive connection to the powered drive wheels. In a second embodiment, the drive source is a small electric motor driving each powered drive wheel. A third embodiment includes a switch controlled solenoid for selectively engaging and disengaging the drive to the rollers. The drive sources and drive wheels may be arranged in many combinations to create separate and distinct drive zones of the load supporting rollers. The drive zones may be energized or deenergized by control mechanisms to provide positive load transport control.
