In accordance with a condition of a flow of the articles (M) on a falling route downstream of the combination weighing apparatus ( ), discharge timing for discharging the articles (M) from the hoppers ( ) is automatically changed among the hoppers ( ). It is thereby possible to promptly detect abnormality in the flow of the articles and to maintain the high operativity and productivity (yield) of the combination weighing apparatus ( ).
