Capsule filling machine and method for operating a capsule filling machine

A capsule filling machine comprising:

• a turntable having a plurality of capsule receiver segments for receiving capsules to be filled;
• at least one insertion station for inserting empty capsules into the plurality of capsule receiver segments;
• at least one filling station for filling the capsules;
• said plurality of capsule receiver segments each having a segment lower part with capsule receptacles for capsule lower parts of the capsules;
• a plurality of test containers for placing on the capsule receptacle of the segment lower part, wherein said plurality of test containers is for recurrent use in the capsule filling machine;
• a container weighing station with a weighing cell for weighing said plurality of test containers;
• and,
• wherein said container weighing station is configured to sequentially weigh individual ones of said plurality of test containers.

A capsule filling machine comprising:

• a turntable having a plurality of capsule receiver segments for receiving capsules to be filled;
• at least one insertion station for inserting empty capsules into the plurality of capsule receiver segments;
• at least one filling station for filling the capsules;
• said plurality of capsule receiver segments each having a segment lower part with capsule receptacles for capsule lower parts of the capsules;
• at least one test container for placing on the capsule receptacle of the segment lower part, wherein said at least one test container is for recurrent use in the capsule filling machine;
• a container weighing station with a weighing cell for weighing said at least one test container;
• wherein said container weighing station has a transport head which is mounted so as to be pivotable about a vertical pivot axis;
• at least one telescopic arm with a gripper for said at least one test container is guided radially with respect to the vertical pivot axis in said transport head;
• and,
• a pivoting travel of the transport head and a linear travel of the at least one telescopic arm are mutually tailored such that said gripper is movable into a region of one of said capsule receptacles and into a region of said weighing cell.

A method for operating a capsule filling machine, wherein the capsule filling machine includes a turntable with capsule receiver segments for receiving capsules to be filled, at least one insertion station for inserting empty capsules into the plurality of capsule receiver segments, and at least one filling station for filling the capsules, wherein the capsule receiver segments each have a segment lower part with capsule receptacles for capsule lower parts of the capsules, wherein the capsule filling machine includes at least one test container, which is provided for recurrent use in the capsule filling machine, for placing on a capsule receptacle of the segment lower part, and wherein the capsule filling machine further includes a container weighing station with a weighing cell for weighing the at least one test container, the method comprising:

• in a regular operating mode, inserting the capsule lower parts into the respective capsule receptacle of the segment lower part in the at least one insertion station, after which the capsule lower parts in the segment lower part are moved via the turntable to the at least one filling station and filled with a product at the at least one filling station;
• in a testing mode, placing the at least one test container on the capsule receptacle of the segment lower part, after which the at least one test container on the segment lower part is moved via the turntable to the at least one filling station and filled there with a multiple of a product quantity provided for the capsule filling, the multiple of the product quantity provided for the capsule filling being at least double;
• and,
• moving a filled test container to the container weighing station and weighing the filled test container at the container weighing station via the weighing cell of the container weighing station and an average mass of an individual actually dosed product quantity is determined via the weighing cell.
