Abstract
A combination weigher of the present invention comprises a plurality of weighing hoppers () each of which includes two weighing chambers () and is capable of weighing objects to be weighed which have been fed to the two weighing chambers, the weighing chambers being capable of independently discharging the objects to be weighed; a plurality of feeding hoppers () which are disposed above the weighing hoppers to respectively correspond to the weighing hoppers, for selectively feeding the objects to be weighed to each of the two weighing chambers of the corresponding weighing hopper; and a control unit () which is configured to perform combination calculation based on weight of the objects to be weighed which have been fed into the weighing chambers of each of the weighing hoppers () to select weighing chambers () forming a combination which have been fed with the objects to be weighed whose total weight falls within a predetermined weight range, and is configured to cause the selected weighing chambers to discharge therefrom the objects to be weighed; and the control unit () is configured to perform the combination calculation in such a way that the number of weighing hoppers whose weighing chambers () are both selected simultaneously to form the combination is limited to a predetermined number or less.
