Abstract:
A combination weighting system for selecting a combination of some of weighing hoppers accommodating therein articles that have been supplied thereto, which combination results in a combination calculated value of measured weights of the articles contained in some of the weighing hoppers forming the combination, falling within a predetermined combination tolerance, and for subsequently discharging the articles in the selected weighing hoppers;wherein determination is made to find if the combination calculated value of the respective measured weights of the containers contained in the selected weighing hoppers is displaced from a post-discharge measured value of the combined articles discharged from the selected weighing hoppers and merged together, which post-discharge measured value is measured after those articles have been discharged from the selected weighing hoppers, so that the hopper which is out of order can be identified based on a result of the determination, obtained from a number of cycles of weighing, and information on the identification numbers of the weighing hoppers that have been selected in the combination calculation.
