ものである。As described above, the conventional container filling method is a method for electrically measuring the height of the container to be filled by the electronic terminal being in contact with the filling liquid, and therefore, the vicinity of the liquid contact portion. Therefore, the structure is complicated and the cost is high. Further, since the lower portion of the filling valve is in direct contact with the liquid in the container, bubbling of the liquid occurs, and at the same time, the electric terminal comes into contact with the upper portion of the foam, causing an error in the filling amount. The filling ability decreases when the bubbling of the liquid is stopped. Therefore, the present invention proposes a novel filling valve device that can estimate and complement the amount of taste of filling without contacting the filling liquid when filling the liquid in the container, and intends to solve the conventional problems.

るようにしている。Next, a third embodiment of the present invention will be described with reference to FIGS. 4 and 5. This embodiment is connected to the gas chamber 145, the pressure sensor 152 and the solenoid valves 141d and f of the first embodiment (FIG. 1). In place of the control valve 142, the air cylinder 171 connected to the solenoid valve 141h and the gas chamber 170 whose volume changes by the air cylinder 171 are replaced.
This is different from the embodiment. Therefore, in this embodiment, the closed space including the upper side of the container K including the gas outflow passage and the liquid inflow passage is connected to the gas chamber 145, and the pressure change causes the volume of the space above the container K to be taken out. The gas chamber 170 connected to the closed space including the upper side of the container K including the gas outflow passage and the liquid inflow passage, instead of calculating the insufficient filling liquid amount.
Is changed by the air cylinder 171, and the insufficient filling amount of the container K is calculated from the change amount of the volume and the change amount of the pressure.

にピストン１７２を戻しておく。Therefore, the difference in the filling process from the first embodiment will be described below. Container head space measurement: A closed space having the same counter pressure as the liquid storage tank 121 is formed above the container K including the gas outflow passage and the liquid inflow passage by closing the liquid valve and the gas outflow passage. The volume of the gas chamber 170 connected to this closed space is adjusted by operating the solenoid valve 141h.
By moving the piston 172 by 71 and increasing it by a certain amount, the pressure in the closed space above the container K and the gas chamber 17 are increased.
The pressure of No. 1 is made to coincide instantaneously, and in the control device 140, the pressure in the closed space before the spaces on both sides are in communication (measured by the pressure sensor 151) and the pressure after the spaces in both sides are in communication (pressure sensor 151). And measure the volume of the enclosed space from
The volume of the gas outflow passage and the liquid inflow passage is subtracted to calculate the insufficient filling amount of the filling liquid. Then, the piston 172 is returned until the next container K arrives.

少なければ、FIG. 5 shows the gas chamber 170 by replacing the closed space above the container K including the gas outflow passage and the liquid inflow passage with a simplified space (volume = V 1 , counter pressure = P 1 ). As for the relationship between the pressure and the volume before and after the volume increase, the volume increased by the movement of the piston 172 of the gas chamber 170 is V 6 , and the pressure is P 6, and if the temperature change is small,

る等の優れた効果を奏することができる。As described above in detail, according to the present invention, since the filling flavor amount can be estimated and complemented without coming into contact with the filling liquid, it is possible to measure the filling flavor level using electricity. It is not necessary to consider an electric insulator in the structure near the contact portion, and the structure is simple and the cost is low. In addition, since the lower part of the filling valve does not come into direct contact with the liquid in the container, the bubbling of the liquid is reduced, and at the same time, this filling amount measurement method is a measurement of the gas space, and since bubbling does not affect the measurement at all, the filling amount accuracy And the filling ability can be improved.
