PROBLEM TO BE SOLVED: To enable suppression of lowering of work efficiency even in the case of the combination measurement of weighed objects whose target combination weights are relatively large.SOLUTION: A combination weigher places a large part of target combination weights that is, for example, about 80% of weighed objects, on a platform weigher 1 that is an external weigher. Meanwhile, the combination weigher calculates a temporary target combination weight by subtracting the weights of the weighed objects placed on the platform weigher 1 from the target combination weights, and selects, from among a plurality of weighing conveyors 8-8on which the weighed objects are placed, a combination of the weighing conveyors in which a combination of the weights of the weighed objects is within an allowable weight range on the basis of the temporary target combination weight. The combination weigher drives the selected weight conveyors to discharge the weighed objects on a carrying conveyor 7, and drives the carrying conveyor 7 to discharge the weighed objects on the platform weigher 1. |
