A combinatorial weighing apparatus includes a circuit for presetting at least one weighing machine which discharges articles for rough charging or selecting at least one weighing machine which discharges articles for rough charging according to a prescribed rule, a combinatorial computing device for computing, as a rough charging weight value, a total weight of articles discharged from preset or selected weighing machines and for selecting a combination of weighing machines which gives a total weight combination equal or closest to a corrective charging weight value which is the difference between a target weight value and the rough charging weight value. The combinatorial weighing apparatus further includes a discharge control means for discharging the rough charging articles from the preset or selected weighing machines at a prescribed timing and for discharging articles for corrective charging from the selected combination of weighing machines at another timing. Rough and corrective charging chutes are provided for collectively discharging rough and corrective charging articles into respective locations. Rough and corrective charging weight data are provided in a single cycle of supplying articles into weighing machines and weighing the articles therein. The rough and corrective chutes are actuatable in coaction with a device for supplying a plurality of containers to a first position in which articles providing the rough charging weight value are charged from the rough charging chute into the containers and articles providing the corrective charging weight value are charged from the corrective charging chute into containers in a second position. |
