Abstract
Abstract Improvements in a weighing or counting method wherein on the basis of weight data on a plurality of groups of articles obtained from a plurality of weighing machines, the respective additive values of all possible or desired number of combinations are found, the additive value of a particular combination which is equal or the nearest to a set value is retrieved, and the weighing machines corresponding to the combination selected are actuated to discharge articles contained therein. During the discharge of articles from the weighing machines corresponding to the selected combination and during the subsequent feeding of fresh articles into the same weighing machines, similar combinatorial operation is effected on the basis of weight data from a fixed number of weighing machines which were not selected, or did not discharge their articles, and a particular combination whose additive value is equal or the nearest to the set value is determined as the combination for the next discharge.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
127 words
A weighing or counting method including the steps of computing combinations on the basis of weight data from a plurality of weighing machines, retrieving a particular combination which is equal or the nearest to a set value and causing the weighing machines corresponding thereto to discharge their articles, said method being characterized in that during the discharge of articles from weighing machines and during the feeding of fresh articles to weighing machines, combinations are computed on the basis of weight data from a fixed number of weighing machines selected from the remaining weighing machines which did not discharge their articles to find a particular combination which is equal or the nearest to the set value, and deciding said particular combination as the combination for the next discharge.
Claim 2
Dependent Claim
127 words
A weighing or counting method including the steps of computing combinations on the basis of weight data from a plurality of weighing machines, retrieving a particular combination which is equal or the nearest to a set value and causing the weighing machines corresponding thereto to discharge their articles, said method being characterized in that during the discharge of articles from weighing machines and during the feeding of fresh articles to weighing machines, combinations are computed on the basis of weight data from a fixed number of weighing machines selected from the remaining weighing machines which did not discharge their articles to find a particular combination which is equal or the nearest to the set value, and deciding said particular combination as the combination for the next discharge.
Claim 3
Dependent Claim
126 words
A weighing method comprising the steps of weighing articles by a plurality of weighing machines, computing combinations of the weight values obtained from said plurality of weighing machines, retrieving a combination whose combination weight is equal or the nearest to a set weight from among said combinations, discharging articles from the weighing machines corresponding to said retrieved combination, computing combinations of the weight values from a fixed number of weighing machines selected from the remaining weighing machines which did not discharge their articles during the discharge of articles from said weighing machines or during the feeding of fresh articles to said weighing machines, and retrieving a combination whose combination weight is equal or the nearest to the set weight as the combination for the next discharge.
Claim 4
Dependent Claim
126 words
A weighing method comprising the steps of weighing articles by a plurality of weighing machines, computing combinations of the weight values obtained from said plurality of weighing machines, retrieving a combination whose combination weight is equal or the nearest to a set weight from among said combinations, discharging articles from the weighing machines corresponding to said retrieved combination, computing combinations of the weight values from a fixed number of weighing machines selected from the remaining weighing machines which did not discharge their articles during the discharge of articles from said weighing machines or during the feeding of fresh articles to said weighing machines, and retrieving a combination whose combination weight is equal or the nearest to the set weight as the combination for the next discharge.
Claim 5
Dependent Claim
140 words
A counting method comprising the steps of weighing articles by a plurality of weighing machines, dividing the weight indicated by each weighing machine by the weight of a single article to convert it into the number of articles, computing combinations of these numbers, retrieving a combination whose combination number is equal or the nearest to set number from among said combinations, discharging the articles from the weighing machines corresponding to said retrieved combination, computing combinations of the numbers associated with a fixed number of weighing machines selected from the remaining weighing machines which did not discharge their articles during the discharge of articles from said weighing machines and during the feeding of fresh articles to said weighing machines, and retrieving a combination whose combination weight is equal or nearest to the set value as the combination for the next discharge.
Claim 6
Dependent Claim
140 words
A counting method comprising the steps of weighing articles by a plurality of weighing machines, dividing the weight indicated by each weighing machine by the weight of a single article to convert it into the number of articles, computing combinations of these numbers, retrieving a combination whose combination number is equal or the nearest to set number from among said combinations, discharging the articles from the weighing machines corresponding to said retrieved combination, computing combinations of the numbers associated with a fixed number of weighing machines selected from the remaining weighing machines which did not discharge their articles during the discharge of articles from said weighing machines and during the feeding of fresh articles to said weighing machines, and retrieving a combination whose combination weight is equal or nearest to the set value as the combination for the next discharge.
