Title: Modular power roller conveyor

Abstract: A modular power roller conveyor is described having a conveyor section for transporting a product unit. The conveyor section comprises a number of active zones, each active zone containing means for sensing the entry of a product unit into the active zone. A programmable controller generates activation signals to a drive roller in response to the means for sensing. A plurality of carrier rollers are slaved to the drive roller within the active zone such that activation of the drive roller actuates all of the carrier rollers to drive the product unit through the active zone and into the next active zone. The programmable controller also generates a deactuation signal to deactivate the active zone as a product unit exits the zone.
