PROBLEM TO BE SOLVED: To shorten a period of time required in weighing processing by suppressing combination failure in combination weighing of an object to be weighed having a comparatively large object weight.SOLUTION: Objects to be weighed sorted into a plurality of weight ranks S, M1, M2, and L by a weight sorting machine 20 are stored in a plurality of stock parts 30a-30d, respectively and are thrown into weighed object input ports 401 of a combination balance 40 divided into groups A, B, C and D so as to correspond to the respective stock parts 30a-30d. Thereby, the combination balance 40 can perform combination operation combining the objects to be weighed of the plurality of weight ranks S, M1, M2 and L to easily obtain combinations and reduce the number of change times of the objects to be weighed due to combination failure to shorten a period of time required in weighting processing. |
