Abstract
A weighing apparatus comprises feeder means for temporarily storing an object to be weighed and discharging the object to be weighed as needed, a plurality of weighing hopper means each having a plurality of storage chambers which are integrally coupled, a plurality of weighing means, provided in correspondence with the plurality of weighing hopper means, for independently weighing weights (referred to as partial weights hereinafter) of objects to be weighed, stored in the storage chambers, and a control apparatus for calculating partial weight values of the objects to be weighed based on weighing signals from the weighing means. The control apparatus combines at least one of the calculated partial weight values and the number of objects to be weighed, calculated from the partial weight values, so as to select a combination closest or equal to at least one of a preset weight or a preset number, causes the selected objects to be weighed to be discharged and collected from the storage chambers, and includes at least a plurality of operation means for calculating at least one of true partial weights and the number of plurality of stored objects to be weighed. The control apparatus is …
