COMBINATION WEIGHING DEVICE AND COMBINATION WEIGHING METHOD

A combination weighing apparatus includes a plurality of hoppers WH that temporarily stores articles conveyed by a conveying unit (CF, DF); a weighing unit WS that weighs a measured value corresponding to a mass of the article stored in each of the hoppers; a controller CU that executes combination weighing that selects a combination of the measured values from a plurality of measured values weighed by the weighing unit and associated with the respective hoppers and causes the hoppers associated with the combination to discharge the articles; and a setting unit (15) that sets a closing mode in which, in a state that the supply of the articles to the conveying unit is stopped, combination weighing is executed on the articles remaining in the conveying unit and the hoppers, the controller executing the combination weighing based on a measured value acquired in a cycle in which the combination weighing failed and corresponding to the articles that were forcibly discharged from at least some of the hoppers and measuring values associated with the respective hoppers weighed in a cycle after the cycle in which the combination weighing failed.
