  • Patent number: 7287637
    Abstract: A conveyor system is provided to limit the vertical fall experienced by a product transported along the conveyor and falling into a collection bin. A sensor in a fixed position relative to the product conveying plane of the conveyor measures product collection height in a collection bin to produce an output signal. A controller dynamically varies the angle between the conveyance plane and the collection bin base plane and the vertical displacement therebetween within a preselected range in order to minimize product damage associated with different fall trajectories from the conveyor into the bin for product. Either the conveyor or the collection bin is pivoted under the command of the controller to accomplish the desired function.
