本発明は容器やびん、例えばウイスキーボトル
に所定量の液、例えばウイスキーを自動的に供給
するための自動注液装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic pouring device for automatically dispensing a predetermined amount of liquid, such as whiskey, into a container or bottle, such as a whiskey bottle.
［従来技術］
重計計例えばロードセルの上に容器を載置し、
そして計量しながら容器内に所定量の液を供給す
る装置は知られている。[Prior art] A container is placed on a weight scale, such as a load cell,
Devices for supplying a predetermined amount of liquid into a container while measuring it are known.
その際、容器に対して液は連続的に供給される

或いは計測時間をみじかくすればよい。しかしな
がら前者では液の供給作業に時間がかかり、また
後者では理論上可能であつてもコスト高となり、
実際上不適である。 At that time, although the liquid is continuously supplied to the container, the signal from the weighing scale is sent for a certain period of time (for example, 4
Therefore, the liquid dispensed during that time interval will be in error and will result in a fraction of the predetermined amount. In order to reduce this error, either reduce the supply amount per unit time, or
Alternatively, the measurement time may be shortened. However, in the former case, it takes time to supply the liquid, and in the latter case, even if it is theoretically possible, it is costly.
Practically unsuitable.

り誤差となる。 Further, liquid injection is usually controlled by an on-off valve provided above the container, but even if the on-off valve is closed, the amount of liquid falling between the on-off valve and the container will still result in an error.

生じやすい。 It is generally known that over-shipment can be prevented by varying the flow rate, as described in, for example, Japanese Patent Application Laid-open No. 84298/1983. However, in such known technology, a value that predicts the overshipment amount from the flow velocity, valve opening degree, and valve response speed is subtracted from the set amount, and the subtracted value is compared with the shipment amount added based on the flow rate signal. When this happens, the injection is stopped. Therefore, when the signal from the flow meter is output, liquid injection is stopped and a predicted value is set, which is likely to cause errors.

適用することはできない。 Further, for example, Japanese Patent Application Laid-open No. 56-66709 discloses a technique for calculating and predicting the input amount from the end of digital conversion to the end of the next digital conversion by calculating it from the past input speed. However, in the case of a liquid injection device, there are various weights or tares of liquid containers to be poured, and therefore, such known techniques cannot be applied.

Therefore, for example, the presence or absence of some residual liquid does not matter. Then, the on-off valve is opened, and the liquid injection operation is started. The weight signal from the weighing scale is transmitted for a certain period of time (for example, 1/4
every second) by the transmitting means. Further, the weight signal is converted into a liquid injection amount by the liquid injection amount calculation means, and the actual liquid injection amount after subtracting the tare weight is calculated. Each time the transmitting means transmits a weight signal, the instantaneous liquid injection amount calculating means calculates the instantaneous liquid injection amount in that time interval from the previous liquid injection amount and the current liquid injection amount.

るので、注液作業は終了する。 On the other hand, the time required to inject the liquid amount obtained by subtracting the current injection amount from the liquid injection amount set using the numeric keypad is calculated by the liquid injection time calculation means.
This operation is performed sequentially, and when the liquid injection time calculated by the liquid injection time calculation means is reached, the opening/closing means closes the on-off valve, so that the liquid injection operation is completed.

適である。 Therefore, according to the present invention, even if the weight signal is transmitted at regular intervals, the amount of liquid injected at each time interval is calculated by dividing, so that the amount of liquid injected is accurate, and
Since the tare weight is subtracted, the liquid can be easily poured using any liquid container, and is extremely suitable as a liquid injection device that determines the amount of liquid to be poured using a weight signal.

記憶される。 Now, as shown in Fig. 1, if the liquid container to be injected, that is, the bottle B, is placed on the load cell 4, the load cell 4 will be able to measure its weight, that is, the tare weight, for example, 600 g.
outputs an analog signal corresponding to
0 is converted into a digital weight signal of 600g,
A weight signal is sent to the liquid injection amount calculation means 21, and 600 g is displayed on the display meter 10. converter 20 here
It is assumed that the weight signal is outputted every fixed period of time, for example, every quarter of a second. That is, converter 2
The time required to convert the weight of 0 is approximately 1/4 second. Therefore, if you want to supply a certain amount Q, for example 300g of whiskey, to bottle B, press "3", "0", "0" on the numeric keypad 9. A signal from the numeric keypad 9 is sent to the first calculation circuit 22 for correction, and at the same time a correction signal is sent from the correction value storage circuit 23.
This correction value storage circuit 23 connects the on-off valve 8 to the funnel 12.
It stores the amount of liquid that has fallen up to this point, and for the sake of clarity, we will assume that the value is 10g. Therefore, the first arithmetic circuit 2 for correction
2 calculates "set value - correction value = set amount" and calculates "290
g" is sent to the storage circuit 24, where "290g" is stored.

「８÷10＝0.8ｇ」を計算する。すなわち１カウン
ト毎に0.8ｇが注液される。 Next, press the liquid injection button 11. Then, the tare, that is, the weight of the bottle B and the funnel 12, ``600 g'' is stored in the tare storage circuit 25, and the liquid injection amount calculation means 21 calculates ``total weight - tare = liquid injection amount'', that is, ``0 g'', and the display meter 10 will be displayed as zero. Further, when the liquid injection button 11 is pressed, an activation signal is input to the opening/closing means 30, the opening/closing valve 8 is opened, and the motor 5 is activated.
Liquid, ie whiskey, is therefore supplied to bottle B. Since the weight signal from the transmitting means, that is, the converter 20 is transmitted every 4 minutes and 1 second, the liquid injection amount calculation means 21 calculates the total weight every [1/4 second (250 msec)] when the weight signal is transmitted from the converter 20. - Tare = amount of liquid injected'' and outputs the amount of liquid in bottle B. (This amount of liquid injected every quarter of a second actually changes a little, but to make the explanation easier to understand, it is assumed to be 8 g.) This output signal is transmitted to the display meter 10,
It is sent to a second arithmetic circuit 26 for subtraction and an instantaneous injection amount calculation means 27 for instantaneous discharge amount calculation. The second arithmetic circuit 26 subtracts the injection amount, which is the output signal of the injection amount calculation means 21, from the value (290 g) set by the storage circuit 24. That is, "set amount - injection amount = remaining injection amount" is output. The instantaneous liquid injection amount calculation means 27 calculates the instantaneous discharge amount "8÷10=0.8g" every fraction of the time interval for generating the output signal from the transmitting means, i.e., the converter 20, for example, 1/10th, that is, 1/40th of a second. ” is calculated. That is, 0.8 g is injected for each count.
このように注液作業を行い、ある時間経過後、

出量値で割り算を行う。 Perform the injection work in this way, and after a certain period of time,
Assume that the current injection amount is 180g. At that time, as described above, the second arithmetic circuit 26 outputs "290
-180=110'' is sent to the injection time calculation means 28 and the counter 29 for subtraction. The liquid injection time calculation means 28 divides the remaining liquid injection amount value from the second calculation circuit 26 by the hourly discharge amount value of the instantaneous liquid injection calculation means 27.
すなわち「110÷0.8＝137.5」が計算される。

される。 In other words, "110÷0.8=137.5" is calculated.
Then, the liquid injection time calculation means 28 sends the value "138" obtained by rounding up the above value to the counter 29 as a counter set signal, and sets the value to "138".
The counter 29 is a circuit that subtracts a set value one by one every "1/40 second" of the measurement time of the instantaneous discharge amount, and when the value becomes zero, the opening/closing means 30
It outputs a valve close and motor stop signal. The number "138" set in counter 29 is
"1" is subtracted every 1/40th of a second, and when it becomes "128" after 1/4th of a second, new weight data is issued by the converter 20, and a new numerical value is output from the liquid injection time calculation means 28. is output to the counter 29 and the numerical value is reset. This operation is repeated one after another.

せればよい。 In FIG. 3, the vertical axis shows the amount of liquid injected, and the horizontal axis shows time. If a constant injection of 8 g is continued every 1/4 second, Q2 = 16 g at current time t2, and if Qn-1 = 280 g at time tn-1, time tn
At this point, Qn = 288g, and the injection work can still be continued. Then, at time tn, when a signal that Qn = 288 g is issued from the liquid injection amount calculation means 21, a signal of "290-288 = 2" is output from the third calculation circuit 26 as described above, and the liquid injection time is The calculation means 28 calculates "2÷0.8=2.5". Therefore, the liquid injection time calculating means 28 inputs "3" to the counter 2.
9 and the counter 29 subtracts "1" every 1/40 second. and counter 2
When the set value of 9 becomes "0", a close signal is issued to the on-off means 30, the on-off valve 8 closes and the motor 5 stops, and when the liquid drips from the valve 8, the weight becomes the set value Q, and the Liquid work is completed. Open/close valve 8
The difference between the weight when the door is closed and the final weight is the weight of the dripping liquid, that is, the value stored in the correction storage circuit 23, and this value is corrected using, for example, the previous value or the average value of several times. It is sufficient if the information is stored in the circuit 23.
