Abstract:
1. A conveyor system, comprising: a conveyor course having at least one curved portion with an axis of curvature and a radius of curvature, wherein a conveying direction pointing along the conveyor course, an upright direction extending parallel to the axis of curvature, and a crosswise direction extending orthogonally to both the conveying direction and the upright direction are associated with this conveyor course, wherein the conveyor course has an upper track and a lower track, said upper and lower tracks being positioned one above the other in the upright direction and extending at a predetermined spacing from one another; wherein the upper track has a track face with a surface normal pointing in a first crosswise direction; wherein the lower track has a track face with a surface normal pointing in a second crosswise direction opposite to said first cross wise direction; a conveyor carriage having at least three rollers, wherein at least one track roller having an axis of rotation extending substantially in the upright direction is assigned to each of the tracks, and wherein at least one of the tracks is assigned a further track roller with an axis of rotation extending substantially in the upright direction, wherein said axis is spaced apart in the conveying direction from the one track roller associated with the same track; and wherein, among the at least three rollers, an upper track roller is in rolling engagement with said track face of said upper track and a lower track roller is in rolling engagement with said track face of said lower track; wherein the axis of rotation of said upper track roller is aligned on the same line with the axis of rotation of said lower track roller; and, whenever the two tracks are each assigned a further track roller, the axes of rotation of these further track rollers are likewise located in alignment with one another, wherein the two tracks are embodied on track units that are embodied separately from one another.
