Patent attributes
A conveyor system including: a track comprising a first magnetic element; and a moving element comprising a second magnetic element for interacting with the track to provide a magnetic force that retains the moving element on the track; wherein absent the magnetic force, the moving element is released from the track. In another aspect, a conveyor system includes: a track having at least one guide rail; and a moving element; wherein a magnetic force controls movement of the moving element in a direction of travel and the magnetic force supports the moving element in a second direction perpendicular to the direction of travel; and wherein the at least one guide rail supports the moving element in a third direction perpendicular to both the direction of travel and the second direction.
