This speed increase causes separation and rotation of the articles and also causes them to arrange in single file along one side of the unscrambler's surface and so discharge them onto a conveyor at the end of the unscrambler remote from that at which the articles were received. One or more lanes are composed of rollers of tapered diameter in order to make the lateral speed increase more uniform.

  • Patent number: 5501315
    Abstract: An unscrambling conveyor includes two side-by-side sets of rollers arranged in a herringbone pattern on either side of a central axis. The rollers of the two sets are positioned at different angles with respect to the axis and the drive speeds for the rollers are chosen to provide equal and opposite forces in the lateral direction and unequal but similarly directed forces in the axial direction. The sets of rollers are divided into zones having progressively increasing roller speeds in the downstream direction with the zones staggered with respect to one another on either side of the central axis. The lateral and axial forces drive articles on the conveyor toward and away from the center axis depending on the roller speeds in the staggered zones and in the downstream direction while imparting a twist to the articles. The successive zones of increasing speed stretch a randomly arranged mass of articles into a single file line.
