PURPOSE:To regulate the number and the weight of an object to be weighed, by selecting the prescribed number among several weighing device having respectively objects to be weighed of the prescribed number and comparing with selection the total weight in the case of all combinations. CONSTITUTION:Among any numbers of weighing devices receiving supplies of objects to be weighed of the prescribed number, prescribed number is selected, and among all combinations ones closest to a prescribed weight are made to be selected. For example, signals from the prescribed number among weighing devices 1-10 loaded with objects to be measured in the same number respectively are combined, and are added with selection by signals from a generating circuit 35 with a selecting and adding device 33, and further whether within allowed limit or not is judged by the adder 37 and a judging circuit 39 and so on. Combinations when within limit are stored in a memory device 47, further the other combinations are also judged successively, thus among all the combinations ones having the total weight closest to a prescribed quantity are made to be selected. In this case, the number is anyway kept to be a prescribed number at all events. |
