  • Patent number: 9726533
    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.

  • Patent number: 4941565
    Abstract: A dispersion feeder used in a combination weighing machine for distributively feeding product to be weighed out to a plurality of weighing units arranged around it. The feeder is characterized in that it includes a mechanism for effecting rotational movement of the center or apex of its dispersion table. This movement exerts a centrifugal force on product fed onto the table, including product in and near the center of the table, thereby ensuring that such product is removed from the table.
