  • Patent number: 12103721
    Abstract: A rotary filling machine for filling containers with bridgeable dry materials includes a turret supporting a plurality of circumferentially spaced drop buckets and a plurality of funnel assemblies located under the drop buckets. A stationary slide plate is located vertically between the funnel assemblies and the drop buckets. The slide plate is configured such that flow paths from the bottoms of the drop buckets to the inlet openings of the funnel assemblies increase progressively in at least a portion of a circumferential extent of the slide plate. Drop buckets are located above the slide plate and rotate with the turret. Each drop bucket is provided with one or more partitions that hinder the “snow-plowing of particles” along the edge of the associated fill opening in the machine's fill plate rather than the sweeping of those particles into the fill opening.
