  • Publication number: 20230192340
    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.

  • Publication number: 20220267041
    Abstract: A rotary filling machine includes a rotatable fill plate with fill openings defined therein, a plurality of circumferentially spaced drop buckets mounted above the fill plate and configured to rotate with the fill plate, and a rotating mounting plate mounted on top of the fill plate and disposed below the drop buckets. Each drop bucket includes an inner radial wall, an outer radial wall, a first sidewall, and a second sidewall surrounding a volume bounded by top and bottom openings. A coupler for each drop bucket includes a first connector, such as a socket, extending from an outer surface of the inner radial wall and a mating connector, such as a post, extending upwardly from the mounting ring. A plurality of ridges or protrusions are formed on a side surface of at least one of the walls to reduce the planar surface area available for adhesion to materials being dispensed.

  • Publication number: 20210323707
    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. When viewed in a direction of turret rotation, the slide plate has an upstream end, a downstream end, and inner and outer edges. A portion of the slide plate is tapered progressively in diameter toward its downstream end such that flow paths from the bottoms of the drop buckets to the inlet openings of the funnel assemblies increase progressively in diameter with the taper of the slide plate. Also provided is a funnel assembly and drop buckets provided with one more partitions that hinder the “snow-plowing of particles” along the edge of the associated fill opening in machine's fill plate rather than the sweeping of those particles into the fill opening.

  • Patent number: 6863913
    Abstract: A method and system for food preparation and processing that determines the bulk density of food particulate matter input into particulate packaging machinery and performs bulk density feedback of packaged food particulate matter. The feedback mechanism inputs bulk density values into a controller that are referred against acceptable values. Where the input values of bulk density are outside the acceptable range the controller automatically alters the food preparation and packaging process to obtain acceptable bulk density values. The method system are applicable to any food manufacturing process, although they are particularly well suited to the manufacture of food in flake, chip, puffed or extruded form.

  • Patent number: 5655692
    Abstract: A quick-connect coupling facilitates the connection of an auger of a dispensing mechanism to the drive shaft of the dispensing mechanism so as to firmly lock the auger from radial, axial, or rotational movement with respect to the drive shaft while inhibiting contamination and facilitating cleaning. The coupling includes a male portion provided on the auger shaft and including one or more pins, a female portion formed in the adapter shaft and including one or more axial and peripheral slots, and a key which firmly locks the pin in the peripheral slot. The key includes a retainer which is affixed to a sleeve or other device serving as a guide and support for the retainer. Upon downward movement of the sleeve along the drive shaft, the retainer acts as a cam to lock the pins in position. If the dispensing mechanism employs an adapter shaft as the drive shaft, an improved quick-connect coupling may also be provided to attach the adapter shaft to the drive mechanism output shaft.

  • Patent number: 4880150
    Abstract: A filling machine for repeatedly dispensing predetermined amounts of particulate material comprises a stationary hopper having two spaced-apart spouts; a motor-driven horizontally rotatable upper plate beneath the spouts and having four groups of receiving holes therethrough and a stationary bottom plate beneath the upper plate and having two groups of dispensing holes therethrough. As the upper plate is rotatably driven, the receiving holes align with the spouts, are filled with material, and then align with the dispensing holes through which the material then falls. A sweeper member above the upper plate directs excess material accumulated on the upper plate into emptied receiving holes approaching a spout. A weighted sleeve on each spout slidably engages the upper plate to inhibit material leakage. Each group of receiving holes has a cup plate on the underside of the upper plate with apertures in registery with the receiving holes and slidably engageable with extension tubes from the receiving holes.
