く、稼動率が下がるという問題があった。(Prior art and its problems) In this type of combination weighing device, the combination accuracy is best when approximately half of the weighing machines participating in the combination are selected as the optimal combination. The amount of articles supplied was controlled so that the total weight value was approximately twice the target weight value. Therefore, when changing the target weight value,
It is necessary to adjust the supply amount of the objects to be weighed accordingly, and when the supply amount is initially changed, it takes a considerable amount of time to settle down to a steady state, so during that time, poor combinations are likely to occur and the operating rate decreases. There was a problem.
また、こうした問題は、目標重量値を変えなくても物品

The object of the present invention is to provide a combination weighing method that reduces the occurrence rate and does not reduce the operating rate of the device.

A combination calculation is performed, and a combination weight value is calculated for each combination. The obtained combined weight value is compared with the target weight value Wa set in the target weight setting section 6, and is either equal to Wa or the upper limit weight signal Wp of the upper limit weight setting section 5 and the lower limit weight signal Wl of the lower limit weight setting section 7. The optimum combination closest to the target weight value Wa is determined within the range of , and a discharge signal Se for discharging the article is given to the weighing hopper of the corresponding weighing machine to discharge the article. Note that the lower limit weight setting section 7 may be omitted and only the weight within the upper limit weight setting range may be discharged, and this method is ideal for weighing products. On the other hand, a supply signal Sf is applied to a pool hopper provided above the weighing machine that discharged the articles, and the articles are supplied to the weighing hopper attached to the weighing machine.

た時、或は物品供給量が不足した時の補充用とする。FIG. 2 is an explanatory diagram of an embodiment of the combined weighing method according to the present invention. In the present invention, the basic idea is to change the number of weighing machines participating in the combination according to the number of weighing machines that provide the target weight value. , the participants will be given priority to selecting items from the weighing machine with the highest number of items. The total number of units that can be selected is, for example, up to 1.
Under normal conditions, the supply amount of goods is adjusted so that 10 weighing machines can always participate in the combination, that is, the goods related to the optimal combination are discharged from around 5 weighing machines each time. Adjust the supply amount so that
The remaining 1, for example 4 weighing machines are used for replenishment when the target weight value increases or when the supply of goods becomes insufficient.

The next combination calculation is performed using a number of weighing machines to speed up the weighing process. In addition, as the number of weighing machines participating in the combination increases, the combination calculation time also increases, so in this example, the combination calculation using 10 weighing machines is used as a base, and if the number of participating weighing machines increases beyond that, the time required for the combination calculation increases. Combination calculation that always includes the weighing machines, that is, adding the increased weight values of the weighing machines to each of the 1023 combined weight values (added values) formed by combining the weight values of the above 10 weighing machines. The calculation is performed to shorten the calculation time.

りに投入された物品の平均重量値Ｙを求める。(1) Find the sum of the total weight of the articles in all the weighing machines that have completed weighing, and divide this by the number of weighing machines to find the average weight value Y of the articles put into each weighing machine.
（２）次に、目標重量値をＹで除算して、目標重量値の
物品を与える計量機台数Ｘを求める。(2) Next, the target weight value is divided by Y to find the number of weighing machines X that provides articles with the target weight value.

なければ、追加供給等の処理を行う。Next, this combination calculation will be explained based on the flowchart of FIG. Previously, if the value of X mentioned above is within the range of
10 weighing machines are selected as described above, and 1023 combination calculations are performed using the selected 10 weighing machines, for example, weighing machine No. Determine (Step a1) 0 If the next determined combined weight value is the optimal combined weight (correct amount) included within the upper and lower limits, the article is discharged from the corresponding weighing machine, and if the correct amount cannot be obtained, Adds another weighing machine to the previous 10 weighing machines and executes a combination operation involving that weighing machine.0For example, if the added weighing machine is called weighing machine NO, @l, then this The weight value is stored in the weighing machine No. ~ [
phase] (step a3), that is, the weight values of weighing machines NO.
U2. ...Add the weight values of weighing machine No. and @ to U 1023, respectively. If the correct amount is still not obtained, select the weighing machine with the next highest selection priority, for example, weighing machine No.
, O is added to the combined weight value of weighing machine No., ■ ~ [stock] (step aS), and if the correct weight is still not obtained, the weight of the next highest ranked weighing machine 1, e.g., weighing machine No. 11, @ is added. The value is weighed by weighing machine N9. (2) - Add to the combined weight value of [stock] (step a7). If the correct amount cannot be obtained through the processing up to this point, processing such as additional supply is performed.
このように、この実施例においては、Ｘが７以下の時は

では、この加算処理が不要となるので、トータルの演算
処理時間は短縮されるのである。In this way, in this example, when X is 7 or less, the number of weighing machines that are combined and discharged may be around 5, so first, the combination calculation is performed using 10 weighing machines, and then If the correct combination cannot be obtained, there may be a supply shortage or a change in the target weight value, so the combination calculation is performed using a total of 11 weighing machines, including one other weighing machine. Combinations are performed so that weighing machines added later are always included in the discharge combination, so that the number of weighing machines to be discharged in combination is around 6. In addition, in combinations that include additional weighing machines, the 1023 combination addition values stored in the previous combination calculation are used, so the calculation again is a simple addition process, and the calculation processing time is shorter than the first time. will be significantly shortened. That is, in the first 1023 combinations, it is necessary to add the weight values of all the weighing machines included in that combination for each combination, but in the second calculation, this addition process is not necessary. , the total calculation processing time is shortened.

If the combined weight value falls within the upper and lower limits, the article is discharged from each corresponding weighing machine, and if the weight is not correct, 1, for example, the weighing machine O and A combination operation including @ is performed (step b5), and if the quantity is not correct, a combination including the primary weighing machine No., @ and @ is performed (
Step b5), if the amount is not correct, weigh @No, 4
A combination including 'b and [phase] is performed (step b7), and a combination calculation is performed using a total of 11fi12 units.

。In any case, since the 1023 combinations of added values from the 10 weighing machines that were initially stored are used,
The number of combinatorial addition processes in each step is 1023, so that even if the number of participating weighing machines increases, the calculation time is substantially the same as in steps ag, a5, a7, etc.

When the number of weighing machines participating in a combination is changed and the change is an increase in the number of weighing machines, the number of weighing machines exceeding 10 must be included in the optimal combination in order to prevent an increase in the combination calculation time due to this change.
