Abstract: A conveyor assembly is provided for accumulating and discharging a column of evenly spaced items. The conveyor assembly includes a receiving conveyor, a discharge conveyor and a belt guiding carriage. The receiving and discharge conveyors each include a plurality of round belts that are interlaced with the receiving belts being at a slightly higher elevation on the receiving end of the system and the discharge belts being at a slightly higher elevation on the discharge end. Both sets of belts pass through a movable carriage that guides the receiving belts from the upper elevation to the lower elevation and the discharge belts from the lower elevation to the upper elevation so that the receiving belts are at a higher elevation on the receiving end of the carriage and the discharge belts are at a higher elevation on the discharge end of the carriage.
