COMBINATION BALANCE

摘要

A combination balance, comprising a plurality of weighing hoppers (4) each of which has two weighing chambers (4a, 4b), weighing the weights of weighed objects charged into the weighing chambers, and capable of discharging the weighed objects for each weighing chamber, a plurality of supply hoppers (3) disposed on the upper side of the weighing hoppers correspondingly to the weighing hoppers and selectively charging the weighed objects into the two weighing chambers of each of the corresponding weighing hoppers, and a control part (10) for selecting the weighing chambers in such a combination that the total weight of the charged weighed objects comes within a prescribed weigh range and performing a discharge operation for discharging the weighted objects from the selected weighing chambers by performing a combination calculation based on the weight of the weighed objects charged in the weighing chambers of the weighing hoppers. The control part (10) performs the combination operation by limiting the quantity of the weighing hoppers (4) for which both two weighing chambers (4a, 4b) are simultaneously selected for combination to a prescribed quantity or below.
