Chain conveyor with free-rotating rollers and retractable flights

Abstract

The present invention relates to an endless conveyor for transporting products, for example packaging units, along a transport path in a transport direction T, wherein the conveyor comprises: ⋅freely rotating supporting rollers () which extend substantially perpendicular to the transport direction, which are connected at both ends to conveyor elements (), and which form an endless transport surface, and ⋅flights (), connected to the conveyor at well-defined positions, which with a control are movable to and away from a carrying position above the transport surface, wherein, after such carrying position has been taken up, a product present on the transport surface is carried along in the transport direction T, wherein the flights comprise strip-shaped thresholds () which, from a rest position below at least the transport surface, can be moved up between the rollers to the carrying position. Suitable to carry and buffer along products over an incline and thus transport them.
