  • Patent number: 4294059
    Abstract: An apparatus receives empty bins and loose articles of random size and shape, such as apples, to be stored within the bins at a fill station. The articles are delivered to an inclined conveyor which has a lower end adjacent to a horizontal conveyor with a stop roller being positioned between the conveyors. When the articles have collected on the inclined conveyor a predetermined distance up the incline, a drive is actuated which simultaneously moves the inclined conveyor upwardly and moves the horizontal conveyor away from the inclined conveyor while rotating the stop roller to permit the articles to move from the inclined conveyor to the horizontal conveyor. This conveyor motion causes the articles to gently cascade down the incline in spread out fashion so that they are transported toward the end of the horizontal conveyor remote from the inclined conveyor and across the entire breadth thereof.
