ABSTRACT:
Each of a plurality of scale units10that constitute a combination weigher is provided with a cut gate11attached to a lower portion of a powdery- or granular-material hopper12, a feeding hopper13for temporarily retaining a powdery or granular material supplied from the cut gate11, a gate-type weighing hopper14for weighing the powdery or granular material supplied from the feeding hopper13, and a collecting chute16for collecting the powdery or granular material discharged from each weighing hopper14and supplying it to a wrapping machine or the like. A load cell15is attached to the weighing hopper14, and the load cell15measures the weight of the powdery or granular material for performing combinatorial computing between the weighing hoppers14. A dust-preventing bellow18is provided in between the respective constituting components: the cut gate11, the feeding hopper13, the weighing hopper14, and the collecting chute16. This makes available a powdery- or granular-material weighing apparatus capable of weighing a powdery or granular material at high speed.
