<p>It is an object of the present invention to provide a weighing device having an improved yield when objects having unfixed individual weights such as natural objects are quantitatively weighed and controlled to be discharged. The weighing device includes: a weighing means; a conveying means; a plurality of discharge parts; discharging means provided corresponding to the discharge parts; and a controlling part. The controlling part includes: a weight setting means for setting a final target weight; an integrating means for integrating the weights of the weighed objects in each of the discharge parts; a calculating means for calculating a final target weight difference in each of the discharge parts, the final target weight difference being a difference between the integration weight and the final target weight; a storing means for storing the final target weight, the integration weight, and the final target weight difference; a comparing means for comparing the weight of the objects measured by the weighing means with the final target weight difference; and a discharging control means for sorting the weighed object to a discharge part having a weight which is no less than the final target weight difference and approximate to the final target weight difference based on the comparison result.</p> |
