Filling apparatus for a powdery product
First Claim
1. In a filling apparatus for a powdery product, especially for a freeze-dried food product, comprising a container conveyor for a plurality of containers, a measuring device for said product, and a plurality of filling funnels placable on said containers, said container conveyor having an entrance portion with a feed belt, a filling zone adjoining said entrance portion and a discharge belt, the improvement wherein a plurality of said filling funnels are attached to a continuously circulating chain conveyor and are guided in the conveying direction above said container conveyor close to said container conveyor, a conveying screw driven synchronously with said chain conveyor is located in said entrance portion of said container conveyor whose conveying helix grips said containers laterally to feed said containers continuously, said containers being movable with a speed corresponding to the conveying speed of said chain conveyor and being spaced according to the spacing between the outlets of said filling funnels, the path taken by said filling funnels and said container conveyor in said entrance portion being inclined relative to each other and said path taken by said filling funnels and said container conveyor in the vicinity of said discharge belt also being inclined relative to each other, said filling funnels being guidable into and out of said containers while said containers are being moved continuously, and a feeder-weigher operating as said measuring device is located above said container conveyor in the vicinity of said filling zone.

Abstract
The filling apparatus for a powdery product, especially for a freeze-dried food product, has a container conveyor for a plurality of containers, a measuring device and a plurality of filling funnels which are placed in the containers. The container conveyor has an entrance portion with a feed belt, a filling zone adjoining it and a delivery belt. A plurality of filling funnels is attached to a continuously circulating chain conveyor and guided in the conveying direction on the forwardly moving strand of a chain conveyor above and close to the container conveyor. A conveying screw driven synchronously with the chain conveyor is located in the entrance portion of the conveying belt. Its conveying helix engages the containers laterally so that the containers are movable with a feed speed corresponding to the conveying speed of the chain conveyor and can be spaced as defined in the spacing between the outlets of the filling funnels. A feeder-weigher used as the measuring device is located in the vicinity of the filling zone above the container conveyor. A continuous product flow is fed to the containers moving past with the conveying speed.

6. A filling apparatus for filling a powdery product, especially for a freeze-dried food product, in a plurality of containers comprising:
-
a container conveyor for a plurality of containers, said container conveyor having an entrance portion with a feed belt, a filling zone adjoining said entrance portion and a discharge belt following said filling zone, said container conveyor in the vicinity of said entrance portion being inclined at an entrance angle β
relative to said container conveyor in the vicinity of said filling zone and said container conveyor in the vicinity of said discharge belt being inclined at a discharge angle -β
relative to said container conveyor in said vicinity of said filling zone,a plurality of filling funnels each having an outlet placable on said containers attached to a continuously circulating chain conveyor and guided in the conveying direction above said container conveyor close to said container conveyor; a conveying screw driven synchronously with said chain conveyor located in said entrance portion of said container conveyor whose conveying helix grips said containers laterally to feed said containers continuously, said containers being movable with a speed corresponding to the conveying speed of said chain conveyor and being spaced from each other defined in the spacing between said outlets of said filling funnels, said filling funnels being guidable into and out of said containers while said containers are being moved continuously; a feeder-weigher operating as said measuring device located above said container conveyor in said vicinity of said filling zone; and a shaking unit connected to a returning strand of said chain conveyor, said returning strand being downstream from said delivery belt but upstream from said entrance position.
