ABSTRACT:
A system having a combinatorial weighing apparatus for obtaining an optimum weight of a batch of articles that exhibit a variable apparent specific gravity, and for packaging the weighed out articles in a packaging vessel. The system includes a volume detecting unit for detecting the volume of the articles supplied, a density detecting unit for detecting the density of the articles based on the volume value obtained from the volume detecting unit and a weight value obtained from the weighing apparatus, and a target weight adjusting unit for adjusting a target weight value within preset allowable limits on the basis of the detected density in such a manner that the volume of the articles discharged into the packaging vessel becomes substantially constant. The system is also provided with a crusher for adjusting the size of individual articles on the basis of the detected density in such a manner that the density of the articles becomes substantially constant.
