<p>The invention relates to a roller conveyor module, comprising at least one rack, a plurality of rollers (10a-d) mounted to said rack in a serial arrangement, wherein the rotating axis (11a-d) of each roller is approximately perpendicular to the longitudinal axis of the rack, and the upper circumferential surface parts of the plurality of rollers define a load carrying plane (100). According to the invention, a lever (40) is provided, said lever being mounted to said rack, wherein the lever is adapted to swivel between an unbalanced position, wherein said lever is arranged at least partially above said load carrying plane (100) and wherein the lever is free to swivel in two opposite directions, a passing position, wherein the lever is arranged below the load carrying plane to allow an item moving on the rollers to pass in the first direction, and a stopping position, wherein a stopping portion (45) of said lever (40) is arranged above said load carrying plane (100) to hinder an item (1) moving on the rollers (10) in a second direction opposite to the first direction.</p> |
