Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a pressurized filling device for filling a container with a filling liquid such as carbonated drinks, and more specifically, the present invention relates to a pressurized filling device that fills a container with a filling liquid such as carbonated drinks. This invention relates to a gas venting device that releases pressure in a space to the outside.

"Prior Art" Conventionally, as a pressurized filling device for filling a container with filling liquid such as carbonated beverages, a plurality of filling valves are provided around a rotating body, and each filling valve is provided with A liquid valve that opens and closes a liquid passage for injecting the filling liquid; a gas valve that opens and closes a gas passage that supplies and discharges gas into the container; a valve opening cam that operates in conjunction with the liquid valve and gas valve of the filling valve to open them and fill the container with the filling liquid and pressurized gas; a first valve closing cam that operates in conjunction with the liquid valve and gas valve of each filling valve to close them; and a pressurized gas provided in each of the filling valves and sealed in the upper residual space in the container. a first gas venting passage for releasing gas to the outside; a first gas venting valve for closing the first gas venting passage; A device equipped with a first gas vent cam that opens the gas vent is known.

In the above-mentioned conventional pressurized filling device, after the inside of the container is sealed before starting filling with the filling liquid, the gas valve and the liquid valve are sequentially opened by the valve opening cam, and pressurized gas is supplied into the sealed container. After increasing the pressure inside the container, the filling liquid is filled into the container, thereby preventing the filling liquid such as carbonated drinks from foaming.

Next, when filling of the filling liquid into the container is completed, the gas valve and the liquid valve are closed by the valve closing cam, and then the gas vent valve is engaged with the gas vent cam to open it, and the container is opened. The pressurized gas in the space remaining in the upper part of the container is gradually released into the atmosphere through the gas vent passage, and when the pressure in that space drops to almost atmospheric pressure, the seal inside the container is released and filling is completed. That's what I do.

In conventional pressurized filling devices, only one set of the above-mentioned valve closing cam, degassing passage, degassing valve, degassing cam, etc. is used, and the dimensions of each of these parts naturally have a large foaming capacity. It was set based on the filling of carbonated drinks with

``Problems to be solved by the invention'' Conventionally, non-carbonated beverages have been filled using the above-mentioned pressurized filling device; The filling efficiency was poor.

In other words, when filling a non-carbonated beverage, even if the pressurized gas remaining in the upper space inside the container is rapidly discharged to the outside, the filling liquid will not foam unlike carbonated beverages, so the degassing time will be shorter. Although this can be done in a short time, it conventionally took the same amount of time as filling carbonated drinks, resulting in a corresponding decrease in filling efficiency.

"Means for Solving the Problem" In view of such circumstances, the present invention includes a second gas vent passage for releasing the pressurized gas sealed in the upper residual space in the container to the outside, and A second gas venting valve is provided to close the second gas venting passage, and the passage area of the second gas venting passage is set to be larger than the passage area of the first gas venting passage;
Further, a second valve closing cam, which is located at a position beyond the first valve closing cam provided outside the rotary body in the rotational direction of the rotary body, is configured to interlock with and close the gas valve and the liquid valve; Second
a second element that engages and opens the gas vent valve;
a degassing cam, and optionally the first gas venting cam.
The valve closing cam is interlocked with the gas valve and the liquid valve and the first gas vent valve is engaged with the first gas vent cam, or the second valve closing cam is interlocked with the gas valve and the liquid valve and the first gas vent valve is engaged with the first gas vent cam. The two gas vent valves are engaged with the second gas vent cam.

"Function" According to such a configuration, optimal filling conditions can be obtained depending on the type of filling liquid, so optimal filling efficiency can always be ensured.

"Example" The present invention will be explained below with reference to the illustrated example.
In FIG. 1, 1 stores a filling liquid 2 inside,
The tank 4 is a rotating body with a pressure gas 3 introduced into its upper space, and 4 is a plurality of filling valves installed at equal intervals on the bottom of the outer periphery of the tank 1, and each filling valve 4 responds to the rotation of the tank 1. At the same time, it rotates in the direction of arrow Y in FIG.

The filling valve 4 has a liquid passage 5 formed in the shaft portion.
and a vent tube 6 which is disposed to penetrate into the liquid passage 5, and the inside of the shaft of the vent tube 6 is used as a gas passage 7 so that the pressure gas 3 in the tank 1 can be introduced into the container 8. At the same time, the gas in the container 8 can be discharged into the tank 1 during filling with the filling liquid. A liquid valve 9 for opening and closing the liquid passage 5 is provided on the outer periphery of the vent tube 6, and the liquid valve 9 is moved downward against the elastic force of a spring 10 to normally open and close the liquid passage 5.
is being closed down.

A conical spreader 11 is attached to the vent tube 6 to allow the filling liquid 2 injected into the container 8 from the liquid passage 5 to flow smoothly along the inner peripheral surface of the container 8. A gas valve 12 for opening and closing the gas passage 7 is attached to the gas valve 12 . This gas valve 12 is linked to a cam lever 14 via an arm 13, and is normally connected to the gas passage 7.
is closed.

Further, as shown in FIG. 2, in the filling section A of the pressurized filling device, the cam lever 14 is positioned at its starting position.
a valve opening cam 20 that engages and rotates the valve opening cam 20;
is provided, and when the cam lever 14 is rotated by the valve opening cam 20, the gas valve 12 and the liquid valve 9 can be sequentially opened.

Further, at each end of the filling section A and the dual-purpose section B continuous thereto, a first valve closing cam 21 and a second valve closing cam are provided which are rotatable between a position engaging the cam lever 14 and a position not engaging the cam lever 14, respectively. 22 are arranged. Each valve closing cam 21,
22 rotates the cam lever 14 in the opposite direction when engaged with the cam lever 14, thereby closing the opened gas valve 12 and liquid valve 9.

However, a first gas venting passage 23 and a second gas venting passage 24 are opened in the liquid passage 5 at positions downstream of the liquid valve 9, and the inner diameter of the opening portion of the first gas venting passage 23 is That is, the flow passage area is set smaller than the flow passage area of the second gas vent passage 24. And each of the above gas vent passages 2
The other ends of 3 and 24 are communicated with the atmosphere through a first gas vent valve 26 and a second gas vent valve 27, respectively, which normally close the respective gas vent passages 23 and 24 by the elastic force of a spring 25. ing.

As shown in FIG. 2, a first gas venting cam 28 that engages with and opens the first gas venting valve 26 is provided over the dual-use section B and the continuous gas venting section C. In addition, a second gas vent cam 29 is provided only in the gas vent section C, which engages with the second gas vent valve 27 to open it.

Air cylinders 31 and 32 are connected to the first gas venting cam 28 and the second gas venting cam 29, respectively. It can be moved to a forward position where it engages valves 26 and 27.

Furthermore, a support member 35 is provided on the lower side of the filling valve 4 and is attached to a guide rod (not shown) so as to be able to move up and down.
A bottle opening gasket 36 that contacts the upper end and seals the inside of the bottle and a guide cone 37 that centers the container 8 are attached.

In the above configuration, when the filling liquid 2 is a carbonated beverage, the air cylinder 31 is operated to
The gas vent cam 28 is moved to a position where it engages with the first gas vent valve 26, and the second gas vent cam 29 is positioned at a retreated position where it does not engage with the second gas vent valve 27. At the same time, the first valve closing cam 21 is placed in a position where it engages with the cam lever 14, and the other second valve closing cam 22 is placed in a position where it does not engage with the cam lever 14. In this case, since the above-mentioned dual-purpose section B is used as a degassing section, sections B and C
and becomes the degassing section.

In this state, when the container 8 is supplied onto the lifting table (not shown) by the supply star wheel 41, the container 8 is lifted up by the lifting table in a portion before the filling section A, and is lifted by the lifting table (not shown). The upper opening of the container 8 that is lifted up is pressed against the bottle opening gasket 36 while being centered by the guide cone 37 and sealed.
At the same time, the lower end of the vent tube 6 is relatively inserted into the container 8.

When the container 8 is sealed by the bottle mouth gasket 36, the cam lever 14 is opened by the valve opening cam 20.
is rotated to open the gas valve 12, and the pressurized gas 3 in the tank 1 flows into the container 8 via the gas passage 7. When the pressure gas 3 flows into the container 8 and the difference between the pressure inside the container 8 and the pressure inside the tank 1 becomes smaller, the elastic force of the spring 10 causes the vent tube 6 to rise and the liquid valve 9 to open. It will be released.

As a result, the filling liquid 2 in the tank 1 flows down in the liquid passage 5, and is filled into the container 8 while being guided toward the inner peripheral surface of the container 8 by the lower spreader 11.
As the filling liquid is filled, the gas in the container 8 is discharged to the upper space in the tank 1 via the gas passage 7.

After the filling liquid 2 filled in the container 8 closes the opening of the vent tube 6, that is, the lower end of the gas passage 7, it rises inside the gas passage 7 to reach the same liquid level as the filling liquid 2 in the tank 1. When the liquid passage 5 rises to
The filling of the filling liquid 2 into the container 8 is stopped.
After this, the cam lever 14 is moved to the first valve closing cam 2.
1 and returned to the original position, the arm 13
is lowered and the gas valve 12 and liquid valve 9 are closed.

Further, when the container 8 is moved to the dual-purpose section B, that is, the gas venting section B, the first gas venting valve 26 engages with the first gas venting cam 28 and is opened. The pressure gas that has been sealed is released to the outside via the liquid passage 5 and the first gas vent passage 23.

At this time, as described above, the first gas vent passage 2
Since the flow path area of 3 is set small, the flow path area of container 8
The gas sealed in the upper space of the
and C, it is gradually released to the outside. Then, when the container 8 passes through the gas venting section C, the first gas venting valve 26 opens the first gas venting cam 2.
8, the first gas vent valve 26 is returned to its original state by the elastic force of the spring 25 and closes the first gas vent passage 23.

Thereafter, the container 8 is lowered by lowering the lifting table.
The upper end opening of the container 88 is separated from the bottle opening gasket 36 to release the sealed state of the container 88, and the container 8, which has been filled in this way, is discharged from the lifting table by the discharge side star foil 42.

Next, when the filling liquid 2 is a non-carbonated drink,
Contrary to the above, the second gas vent cam 29 is advanced to the forward end position where it engages with the second gas vent valve 27, and the first gas vent cam 28 is retreated to a position where it does not engage with the first gas vent valve 26. In addition, the first valve closing cam 21 is rotated to a position where it does not engage with the cam lever 14, and the second valve closing cam 22 is moved to a position where it is engaged with the cam lever 14.

In this case, the dual-purpose section B is used as a filling section, and the container 8 is continuously filled with filling liquid in both filling sections A and B. Therefore, since the effective angle of filling increases, the speed can be increased by the amount corresponding to the above-mentioned dual-use section B, and therefore the filling efficiency can be improved and the container throughput per unit time can be increased. It becomes like this.

The pressure in the remaining space of the container 8 is discharged to the atmosphere only through the gas venting section C.
Since the flow area of the second gas venting passage 24 is set large, the pressure inside the container 8 can be sufficiently released to the atmosphere even in the short gas venting section C.
Moreover, even if the pressure is suddenly released into the atmosphere, it will not foam like carbonated drinks.

Note that in this embodiment, the first gas venting cam 2
8. The second gas venting cams 29 are configured to be movable by air cylinders 31 and 32, respectively, but they may be moved manually, or the respective gas venting cams 28 and 29 may be Alternatively, the filling liquid 2 may be detachably attached to the machine frame, and both may be replaced as appropriate depending on the type of filling liquid 2. Also, even if both filling liquids are carbonated drinks,
Of course, the present invention can be applied depending on the level of foamability of each carbonated beverage.

``Effects of the invention'' As described above, according to the invention, the remaining space in the upper part of the container can be depressurized in an appropriate time depending on the type of filling liquid, so it is more efficient than conventional methods. The effect that filling work can be performed is obtained.
