ABSTRACT:
A roller conveyor which includes idler rollers which are drivable in a driving direction in response to rotational driving of a drive portion of the rollers, and which are freely rotatable in the driving direction relative to the drive portions of the rollers, in order to allow for coasting of articles or products on the roller conveyor. The rollers include one-way clutch devices which may drive the rollers in the driving direction in response to activation or engagement of a drive means to convey products along the conveyor. The clutch devices also allow the rollers to continue to rotate in the driving direction after the driving means has been deactivated or disengaged from the rollers. The roller conveyor thus may convey articles along multiple zones of the conveyor and may accumulate articles on the zones, such as in response to article sensors positioned along the roller conveyor.
