Abstract
Combinational weighing by ranks is carried out by supplying articles of different weights to a plurality of weighing devices one at a time, measuring individual weights of these articles by the weighing devices, classifying the weighed articles individually into ranks according to their measured weights, and carrying out combinational weighing only on those of the weighed articles in a same rank. The combinational weighing is carried out preferentially on the articles in the most populated rank. An apparatus for this method not only includes a plurality of weighing devices, an article supplying units adapted to supply articles of different weights one at a time to these weighing devices, and a device for carrying out combinational calculations but also is adapted to classify weighed articles into ranks according to the measured weights. A system for combinational weighing includes such a combinational weighing apparatus, a packaging machine for receiving articles of a combination selected by the apparatus and packaging them to produce a packaged product, a sorter for sorting these packaged products by the ranks, and a control unit for controlling the operations of the packaging machine and the sorter according to the rank of the articles to be packaged together.
