A device for grouping solid articles so as to have a predetermined total number by combination selection technique, in which a plurality of sub-groups of articles are prepared, the number of articles in each sub-group is detected, some of these sub-groups are successively extracted in accordance with a predetermined mathematical combination, the numbers of articles in the extracted sub-groups in each combination are summed to obtain the total number of said combination, the total numbers of the successive combinations are sequentially compared with a predetermined reference number and, when coincidence is obtained between both, the combination of sub-groups is selected to be packed together, so that each pack or bag contains the predetermined number of articles.
A device for grouping articles by combination selection so as to have a predetermined number, comprising a plurality of vessels each containing a plurality of articles, means for determining the number of said articles in each of said vessels and producing electric signals indicative of said number of articles in each vessel, means for selectively extracting the electric signals successively in accordance with a predetermined set of combinations, adder and comparator means for summing the extracted combinations of signals sequentially and producing an output when the number indicated by each of the sums falls within a predetermined range, and memory means responsive to the output of said adder and comparator means for storing the combination at that time.
