Abstract:
A combination weighing device 1 includes: a plurality of weighing hoppers 6 which receive articles supplied from an outside, weigh the articles, and discharge the articles; a plurality of booster hoppers 7 which are respectively disposed right below the plurality of weighing hoppers 6 and receive the articles discharged from the weighing hoppers 6; and a control unit 20 which calculates a combination of weighed values so that a total value becomes a target value from a plurality of weighed values respectively correlated with the weighing hoppers 6 and the booster hoppers 7, in which the control unit 20 extracts the weighing hopper 6, corresponding to the booster hopper 7 having the article existing therein and capable of using the weighed value of the article in next combination calculation, as a zero-correction target.
