Abstract
A weighing method and apparatus for charging articles to be weighed into a plurality of weighing hoppers, measuring the weights of batches of the charged articles by weight sensors, selecting, based on the measured weight of each article batch, a combination of the articles batches giving a total weight closest to a target weight value, and discharging the selected article batches from the weighing hoppers. In charging articles into the weighing hoppers, the weighing method includes a step of controlling a dispersing feeder so as to charge the articles into the weighing hoppers with a target charge quantity which is determined on the basis of the number of weighing hoppers and the target weight value, and which serves as the target of the charging operation. The result is a highly accurate weighing operation. The weight of articles charged into an auxiliary hopper is determined based on the extent to which the weights of unselected article batches deviate from the target weight value, and control is effected so as to minimize the deviation for the overall system.
