Abstract: Batches of articles are charged randomly into a plurality of weighing heads, respectively, and weighing data items which are generated respectively by the weighing heads, are added in combinations. The weighing data items from those weighing heads fewer than all of the weighing heads, preferably substantially half of the weighing heads, are picked up and repeatedly added together to provide a wide variety of combinations of added weighing data items. One of such combinations which gives the added data items equal or closest to a set value is selected to open the weighing heads for discharging a desired combination of batches of articles.

Abstract: A combinatorial weighing or counting method of the type in which weight data items from a plurality of weighing machines are combined to find an optimum combination giving a total combined value equal or closest to a target value within preset allowable limits, and the weighed articles are discharged from the weighing machines constituting the optimum combination. Apparatus for practicing the method includes a first storage device provided individually for each of the weighing machines. The method includes the steps of clearing the status of the first storage device corresponding to those weighing machines that participate in the optimum combination and updating by a predetermined quantity the status of the first storage device corresponding to those weighing machines that do not participate in the optimum combination. The clearing and updating are carried out each time an optimum combination is found, and it is discriminated whether the status of each of the first storage devices exceeds a preset value. Then, from combinations including at least one weighing machine corresponding to whichever of the first storage devices has a status which exceeds the preset value, a combination is selected which has a total combined value closest to the target value within the preset allowable limits. Finally, the weighed articles are discharged from the weighing machines participating in the combination.
