DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an indicating method used in connection with a combinatorial weighing apparatus or combinatorial counting apparatus capable of weighing or counting with high accuracy, and more particularly it relates to an indicating method which is convenient to check whether the microcomputer incorporated in the apparatus for combinatorial computations is correctly operating according to a program assigned thereto and to check variations in the weights in the combinations or the numbers of objects in the combinations.
BACKGROUND OF THE INVENTION
It is known that combinatorial computation and the like operations are performed by a microcomputer in a combinatorial weighing (or counting) apparatus which computes combinations of sets of objects being weighed which vary in weight, retrieves the combination which satisfies a set weight value and discharges it or which computes combinations of sets of objects being counted which vary in number, retrieves the combination which satisfies a set number and discharges it. When objects discharged by such system are later examined by separate weighing (or counting), it is sometimes found that they have been discharged with a value that considerably deviates from the set value. However, it is usual with this type of apparatus that it is utterly impossible to check the computations performed by the microcomputer. Therefore, even if such a trouble occurs, there is no ascertaining whether the trouble is due to errors on the part of the microcomputer or the weighing machines. Further, even if the discharged objects are weighed (or counted) again for check up and found to satisfy the set value, it has been still unknown whether the value is actually the nearest to the set value. More particularly, if a quantity of objects whose weight (or number) is exactly equal to the set value are discharged, there would be no problem, of course, but if a quantity of objects whose weight (or number) is more or less deviated from the set value are discharged, there is no knowing whether the combination of objects whose value is actually the nearest to the set value has been discharged or a combination of objects whose value is, e.g., the second nearest to the set value has been discharged owing to a mulfunction of the microcomputer.
SUMMARY OF THE INVENTION
Accordingly, with the conventional problems as described above in mind, the present invention is intended to improve the same. To this end, the invention provides an indicating method wherein combination weights or numbers obtained by combinatorial computations are indicated as arranged in the order of approximation to a set value or the combination which has the highest degree of satisfaction of the set value is indicated, thereby making it possible to check whether the computations by the microcomputer are correct or to check variations in the results of the computations.
The invention may be divided into two forms according to the mode of indication for check up.
The first form (I) is such that combination weights (or combination numbers) which are the results of combinatorial computations are rearranged in the order of approximation to a set value so that they can be indicated in order.
The second form (II) is such that combinatorial processing is performed again by the same manner as that for combinatorial computations for discharge, to allow the highest degree of satisfaction of a set condition to indicate the first-rank combination, so as to check whether the latter conforms to the discharged combination.
According to the first form (I) of the invention, the results of combinatorial computations are arranged in the order of approximation to a set value and can be thereby checked and by examining the same it is possible to check whether the microcomputer has correctly operated according to a program assigned thereto. Further, by this checkup it is also possible to know variations in the combination weights and combination numbers. According to the second form (II) of the invention, it is possible to check c
