Abstract
A combinatorial weighing system designed for weighing out a desired number or weight of articles, wherein groups of articles are respectively weighed by a plurality of weighing machines, combinatorial addition is performed on all or a fixed number of possible combinations for weighed values obtained, a particular combination whose combination value is equal or the closest to a set value is selected, and articles are discharged from the weighing hoppers corresponding to the selected combination. It is contemplated to improve performance of this system by ensuring that groups of articles successively discharged from the weighing hoppers are collected separately one from the other without intermingling. To that end, the weighing hopper may have two discharge ports so as to discharge articles toward different discharge paths defined in a chute.
