ABSTRACT:
A novel combination weighing system which substantially reduces the necessary time for each cycle of operation as compared with the conventional combination weighing system. The system involves sampling a weight indicative signal at a predetermined time point prior to each weighing unit reading stabilization, calculating from each unstable weight indicative signal an estimated stable weight indicative value, executing a combination operation using the estimated stable weight indication values, storing those combinations obtained which satisfy a predetermined weight condition, and calculating the sum weights of the stored combinations using weight indicative signals obtained after stabilization of the weighing units to select a combination whose sum weight satisfies the predetermined weight condition.
