Abstract
A weigher-conveyor has a conveyor which is for transporting an object and is supported by a weighing device such that the weight of the object on the conveyor can be measured while it is being transported. A detector is disposed near the downstream end of the conveyor and, when the presence of an object on the conveyor is detected, a control unit determines whether weight signals from the weigher are already stable. If they are stable, the conveyor continues to be driven and a weight value indicated by the stabilized weight signals is outputted. If they are still unstable, the conveyor is stopped until the weight signals stabilize. A weight value indicated by the stabilized weight signals is outputted in this situation.
