Abstract: A weighing apparatus comprise a large throw-in weighing hopper which is fed with objects having a weight which is less than a target weight of the objects, holds the objects which are weighed, and discharges the weighed objects; a plurality of medium throw-in weighing hoppers which are respectively fed with the objects having weights adjusted with a different ratio, hold the objects for which combination calculation is performed based on the weights of the objects, and discharge the objects based on a result of the combination calculation; and a loss-in weight hopper which is used in loss-in weighing and performs loss-in discharge of the objects.

Abstract: A weighing apparatus (100) comprise a large throw-in weighing hopper (21) which is fed with objects having a weight which is less than a target weight of the objects, holds the objects which are weighed, and discharges the weighed objects; a plurality of medium throw-in weighing hoppers (64, 65, 66, 44) which are respectively fed with the objects having weights adjusted with a different ratio, hold the objects for which combination calculation is performed based on the weights of the objects, and discharge the objects based on a result of the combination calculation; and a loss-in hopper (42) which is used in loss-in weighing and performs loss-in discharge of the objects.

Abstract: Each of a plurality of scale units 10 that constitute a combination weigher is provided with a cut gate 11 attached to a lower portion of a powdery- or granular-material hopper 12, a feeding hopper 13 for temporarily retaining a powdery or granular material supplied from the cut gate 11, a gate-type weighing hopper 14 for weighing the powdery or granular material supplied from the feeding hopper 13, and a collecting chute 16 for collecting the powdery or granular material discharged from each weighing hopper 14 and supplying it to a wrapping machine or the like. A load cell 15 is attached to the weighing hopper 14, and the load cell 15 measures the weight of the powdery or granular material for performing combinatorial computing between the weighing hoppers 14. A dust-preventing bellow 18 is provided in between the respective constituting components: the cut gate 11, the feeding hopper 13, the weighing hopper 14, and the collecting chute 16.
