CONVEYOR BELT HAVING BIDIRECTIONAL STACKED ROLLERS

摘要

A conveyor belt and a belt module having multiple roller sets, each roller set including a bottom roller in contact with an axially elongated top roller. Driving the bottom roller in a first direction causes rotation of the top roller in an opposite angular direction. The bottom rollers in first longitudinal lanes are arranged to rotate obliquely toward one side of the belt, and the bottom rollers in second lanes are arranged to rotate toward the other side of the belt. Either the first lanes of roller sets or the second lanes can be selectively actuated to direct articles conveyed atop the top rollers rearward and toward one side of the belt or the other or to receive articles fed onto the belt from either side.
