Abstract

Disclosed in a combinatorial weighing apparatus having a plurality of weighing hoppers, a plurality of weighing machines, associated with respective ones of the weighing hoppers, for weighing or counting articles introduced into each of the weighing hoppers, and a chute for collecting the articles discharged from the weighing hoppers. The apparatus operates by computing combinations based on weight values provided by the weighing machines, and causing weighing hoppers, belonging to a combination selected as a result of the combinatorial computations, to discharge their articles into the chute one hopper at a time with a predetermined time delay intervening between the discharge operations.
