に、その分だけ計量精度が低下する。The accuracy of combined weighing depends on the number of tanks participating in the combined calculation. Therefore, in order to improve the measurement accuracy in the apparatus shown in FIG. 4, it is necessary to increase the number of measuring tanks, but increasing the number of measuring tanks significantly increases the price of the apparatus. In the device shown in Figure 5, the weight of the articles in the auxiliary tank is added to the combination calculation in addition to the weight of the items in the weighing tank; in the device shown in Figure 6, the weighing tank does not participate in the combination calculation; Individual prize 2
Since the combination calculation is performed on the weight of articles in each auxiliary tank, the accuracy of combined weighing can be improved with a small number of weighing tanks. In the case of the device shown in Fig. 7, the structure of the weighing tank is simpler than that of the device shown in Fig. 5, but because the conditions for the weight of the articles in the weighing tank to participate in the combination calculation are restricted, Weighing accuracy decreases.

計量精度を得ることを目的とする。In this invention, the structure of the combination weighing device used is similar to that shown in Fig. 6, but by including the weight of the articles in the weighing tanks in the combination calculation, sufficient measurement accuracy can be achieved with a smaller number of weighing tanks. The purpose is to obtain.

槽内の物品重量が次の条件で参加する点に特徴がある。In this invention, there are two auxiliary tanks in a series including one measuring tank, and the measuring tank is configured so that the weighed article can be discharged into either one of the auxiliary tanks. This is the same as the combination weighing device shown. However, the combined calculation is characterized in that in addition to the weights of the articles in both auxiliary tanks, the weight of the articles in the weighing tank also participates under the following conditions.

即ち、計量槽内の物品重量は、同一系列内の何れか一方
の補助槽内の物品重量と組合さった形で組合せ演算に参
加でき、かつ同一系列内の何れか一方の補助槽が空であ
れば単独で参加できる。In other words, the weight of the article in the weighing tank can participate in the combination calculation in combination with the weight of the article in one of the auxiliary tanks in the same series, and even if one of the auxiliary tanks in the same series is empty. You can participate alone.

In this case, the number of participating tanks can be easily equivalent to that shown in FIG. 5 or 6. In addition, in this invention, since the measuring tank participates in the combination calculation in combination with the auxiliary tank, the measuring accuracy is improved accordingly, or it is also possible to reduce the number of measuring tanks by reducing the number of series.

安価に得ることができる。In addition, in this invention, since the articles in the weighing tank are discharged through the auxiliary tank, it takes a long time to discharge them, and when the auxiliary tank is empty, it takes a long time to load the articles into the weighing tank and weigh them. In addition to the time required, the operation cycle is much longer than that shown in Figure 4 due to the time required for the auxiliary tank and the rear tank.
It is also longer than those shown in FIGS. 5 and 6. Therefore, according to the present invention, a combination weighing device can be obtained at low cost in cases where operating speed is not so required but sufficient weighing accuracy is required.

起こって全体の組合せ計量の精変を低下させる恐れは少
いので、これに対する禁止措置は不要である。However, the probability that these will occur is small, and there is little risk that they will occur again and reduce the precision of the overall combinatorial measurement, so there is no need for prohibitive measures against them.

上述の実施例では、組合せを構成する槽数が５槽以上に

ると、その回復に時間がか＼す、毎回の組合せに参加で
きる槽数が１０槽以下になる状態が長期化するおそれが
ある。In the above embodiment, it is not preferable that the number of tanks constituting the combination is five or more. The reason for this is that since there are only four measuring tanks, empty tanks can only be replenished with articles at a maximum of four tanks at a time. If five or more tanks become empty at one time, it will take time to recover, and there is a risk that the number of tanks that can participate in each combination will be 10 or less for a long period of time.

この対策としては、計量槽へ供給される物品の量を組合

ことが望ましい。Countermeasures include regulating the amount of goods supplied to the measuring tanks so that the combination consists of 3 to 4 tanks, and issuing an alarm if the combination consists of 5 or more tanks. It is desirable to take measures such as prohibiting combinations of more than one tank.

を検討する。The accuracy of combination weighing is determined by the number of combinations that can be obtained, and this number of combinations is generally determined by the number of tanks that can participate in the combination calculation. In the case of the above embodiment, the average number of tanks participating in the combination calculation is 11, but since there are conditions attached to the participation of measuring tanks, in the conventional example shown in Fig. 4, there are 11 measuring tanks. It will not be the same as if it existed. Therefore, the number of combinations obtained in the above embodiment will be considered.

In some cases, there are several measuring tanks. Therefore, since the number of participating tanks is always 8, as in the case of 8 tanks in the conventional example shown in FIG. 8C4=70 passes.

If there is one tank, one measuring tank or auxiliary tank is empty, so there are seven such sets of measuring tank and auxiliary tank. Assuming that the combination consists of a total of 3 tanks, 1 set of tanks selected in this way and 1 tank selected from 6 tanks of other series, the number of combinations is 7 × 601 == There are 42 ways. In addition, the combination is selected as described above.
Assuming that the system is composed of a total of 4 tanks: the group tank and 2 tanks selected from 6 tanks of other series, the number of combinations is ヮ×602=105.

This shows that it is possible to obtain much higher measurement accuracy than 84 passes when a tank is purchased and 126 passes when a four-tank configuration is used.
