ABSTRACT:
A combinatorial weighing system having N weighing machines for weighing out articles to a final target weight value P which is greater than the maximum weighing capacity of the system. The system operates by discharging articles from all N weighing machines, discharging articles from some of the N weighing machines one time at most, and obtaining a difference value between the final target weight value P and the total weight of articles discharged in the foregoing steps. A combinatorial computation is then performed using the difference value as a target weight value Y, and articles are discharged from a combination of weighing machines selected by the combinatorial computation. The total weight value of articles discharged in the foregoing steps attains a value equal to the final target weight value P or closest to the final target weight value P within preset allowable limits.
