  • Patent number: 4961446
    Abstract: A container filling system is disclosed that produces controlled volumes and weights of filler material for discharge into containers. The system includes a material feed subsystem that provides a source of longitudinally aligned filler material of uniform density or a plug flow of substantially homogenous, amorphous filler material. A rotating measuring subsystem includes measuring chambers that receive predetermined amounts of the material for transfer to a discharge subsystem. The material is transferred into the measuring chambers in an axial direction and is transferred for discharge into the containers in the same direction. More particularly, the rotating discharge subsystem includes a plurality of discharge stations that receive both the measuring chambers and containers immediately below the chambers. Plungers are supported above the measuring chambers and are vertically controlled by a cam to move downward with rotation of the discharge subsystem.

More particularly, the rotating discharge subsystem includes a plurality of discharge stations that receive both the measuring chambers and containers immediately below the chambers. Plungers are supported above the measuring chambers and are vertically controlled by a cam to move downward with rotation of the discharge subsystem. As a result, the material is forced from the measuring chamber into the container.
