ABSTRACT:
A combinatorial weighing system for combinatorially weighing articles by obtaining an optimum combination of weight values produced by a plurality of weighing machines each of which contains a supply of the articles. The system includes a circuit for detecting a malfunction in any of the weighing machines, and a circuit for excluding weighing machines, detected as having malfunctioned, from participation in combinatorial weighing, and for executing combinatorial weighing using weighing machines other than the excluded weighing machine. When the number of excluded weighing machines exceeds a predetermined number, however, the weighing operation is halted. Even if several of the weighing machines malfunction, therefore, operation is allowed to continue, without terminating the overall weighing operation.
