A destacking conveyor (10, 10') comprising: a lower infeed end (18; 64) and an opposite upper discharge end (19; 65); an array of rollers (20; 60) arranged to form an inclined conveying plane extending in a conveying direction from the lower infeed end (18; 64) to the upper discharge end (19; 65) at an inclination angle (α), wherein the rollers (20; 60) are rotatable about axes perpendicular to the conveying direction, the array of rollers (20; 60) including: a first set of the rollers (20; 60) in a first zone extending in the conveying direction from the lower infeed end (18; 64) a first distance defining the upper end of the first zone, wherein the first set of rollers (20; 60) in the first zone are configured such that they are continuously activated to rotate in the conveying direction; a second set of the rollers (20; 60) in a second zone extending in the conveying direction from the upper end of the first zone a second distance defining the upper end of the second zone; characterized in that the conveyor (10, 10') further comprises an actuator, which is configured for selectively activating the second set of rollers (20; 60) in the second zone to rotate in the conveying direction and selectively deactivating the second set of rollers (20; 60) to rotate freely about their axes. a lower infeed end (18; 64) and an opposite upper discharge end (19; 65); an array of rollers (20; 60) arranged to form an inclined conveying plane extending in a conveying direction from the lower infeed end (18; 64) to the upper discharge end (19; 65) at an inclination angle (α), wherein the rollers (20; 60) are rotatable about axes perpendicular to the conveying direction, the array of rollers (20; 60) including: a first set of the rollers (20; 60) in a first zone extending in the conveying direction from the lower infeed end (18; 64) a first distance defining the upper end of the first zone, wherein the first set of rollers (20; 60) in the first zone are configured such that they are continuously activated to rotate in the conveying direction; a second set of the rollers (20; 60) in a second zone extending in the conveying direction from the upper end of the first zone a second distance defining the upper end of the second zone; characterized in that the conveyor (10, 10') further comprises an actuator, which is configured for selectively activating the second set of rollers (20; 60) in the second zone to rotate in the conveying direction and selectively deactivating the second set of rollers (20; 60) to rotate freely about their axes. a first set of the rollers (20; 60) in a first zone extending in the conveying direction from the lower infeed end (18; 64) a first distance defining the upper end of the first zone, wherein the first set of rollers (20; 60) in the first zone are configured such that they are continuously activated to rotate in the conveying direction; a second set of the rollers (20; 60) in a second zone extending in the conveying direction from the upper end of the first zone a second distance defining the upper end of the second zone; characterized in that the conveyor (10, 10') further comprises an actuator, which is configured for selectively activating the second set of rollers (20; 60) in the second zone to rotate in the conveying direction and selectively deactivating the second set of rollers (20; 60) to rotate freely about their axes.
