It is sectional drawing which shows the upper part of a filling valve | bulb and shows operation | movement of the valve rod in 2nd Embodiment. It is a figure for demonstrating the database for supplementing the insufficient filling amount.

[First Embodiment]
Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.
As shown in FIG. 1, the beverage filling facility according to this embodiment includes a supply conveyor 01, a transfer wheel 02, a liquid filling device 03, a transfer wheel 04, a capper 05, a discharge wheel 06, and a discharge conveyor 07.
In this beverage filling facility, each of the transfer wheel 02, the liquid filling device 03, the transfer wheel 04, the capper 05, and the discharge wheel 06 has an outer periphery so that the container 3 (for example, a plastic bottle) can be held and conveyed. The part is provided with holders at equal intervals along the circumferential direction. Thereby, each of the transfer wheel 02, the liquid filling device 03, the transfer wheel 04, the capper 05, and the discharge wheel 06 is rotated and grips the container 3 to be conveyed and delivered.

For this reason, the container 3 conveyed by the supply conveyor 01 is gripped by the holder of the transfer wheel 02 at the position A and conveyed from the position A to the position B. At the position B, the container 3 is transferred from the transfer wheel 02 to the liquid filling device 03, held by the holder of the liquid filling device 03, and conveyed from the position B to the position C. When transported from the position B to the position C, the container 3 is filled with the liquid via the filling nozzle provided in the liquid filling device 03.

Further, the container 3 is moved from the liquid filling device 03 to the transfer wheel 04 at the position C, from the transfer wheel 04 to the capper 05 at the position D, from the capper 05 to the discharge wheel 06 at the position E, and to the discharge wheel 06 at the position F. Is delivered to the discharge conveyor 07 and conveyed. In the capper 05, capping for covering the container 3 is performed.

As shown in FIG. 2, in the liquid filling device 03, the turning table 2 rotates around the turning axis G in a horizontal plane. A plurality of filling valves 100 and a plurality of holders 20 are arranged in pairs on the outer peripheral edge of the turning table 2 at equal intervals along the circumferential direction.

A liquid storage tank 30 is disposed above the swivel table 2. The liquid storage tank 30 rotates synchronously with the turning table 2. The liquid storage tank 30 and each filling valve 100 are connected by a liquid supply pipe 120.

A flow path 102 extending in the vertical direction is formed in the central portion of the main body block 101 of the filling valve 100, and a liquid valve (valve portion) 103 is disposed inside the flow path 102. A valve seat 102a is formed in the discharge port 102b below the flow path 102. When the liquid valve 103 moves downward and contacts the valve seat 102a, the discharge port 102b is closed and the flow of the beverage 31 is blocked. When the liquid valve 103 moves upward and leaves the valve seat 102a, the beverage 31 is discharged from the discharge port 102b.
The liquid valve 103 is connected to an air cylinder (drive cylinder) 50 through a valve rod (rod) 104. Then, by driving the air cylinder 50 in the vertical direction, the liquid valve 103 moves in the vertical direction (vertical direction) to be in an open state or a closed state.

The filling nozzle 15 is disposed at the lower end of the main body block 101, and the beverage 31 flowing down from the flow path 102 through the discharge port 102b is poured into the container 3.

The holder 20 is fixed to the swivel table 2, holds the container 3, and holds the held container 3 at a position below the filling nozzle 15 of the filling valve 100.

Beverage 31 such as a beverage to be filled in the container 3 is stored in the liquid storage tank 30. Further, in the interior of the liquid storage tank 30, a gas corresponding to the type of the beverage 31 to be filled is stored in a space above the stored beverage 31 (hereinafter referred to as a gas phase).

The liquid supply pipe 120 has an upper end communicating with the liquid storage tank 30, and a lower end communicating with the supply port 102 c formed at the upper part of the flow path 102 of the filling valve 100. 100 is connected.
A counter pipe 37 is provided between the filling valve 100 and the liquid storage tank 30, and a counter valve 35 is provided in the counter pipe 37. The counter pipe 37 connects the gas phase of the liquid storage tank 30 and the inside of the filling valve 100 and opens the counter valve 35, whereby the pressure inside the filling valve 100 and the pressure of the gas phase of the liquid storage tank 30 can be made the same.

In such a liquid filling device 03, when the liquid valve 103 is moved upward by the air cylinder 50, the beverage 31 in the liquid storage tank 30 passes through the liquid supply pipe 120 and the flow path 102 of the filling valve 100, and the filling nozzle 15, the inside of the container 3 held by the holder 20 is filled. At this time, the filling flow rate is measured by an electromagnetic flow meter (not shown), and when the measured filling flow rate reaches a predetermined specified amount, the liquid valve 103 is moved downward by the air cylinder 50 until it hits the valve seat 102a. .

Further, as shown in FIG. 4, in order to separate the inside of the flow path 102 of the filling valve 100 from the working space of the air cylinder 50, a seal member 105 made of a corrugated pipe and extending and contracting in the axial direction is formed on the upper portion of the rod 104. Is provided. An upper flange 105 a is formed on the upper end of the seal member 105 so as to project outward. The upper flange 105a is held by being sandwiched between a plurality of

members

101A and 101B constituting the main body block 101.
In addition, a lower flange 105b is formed at the lower end portion of the seal member 105 so as to project to the inner peripheral side. The lower flange 105b is held by being sandwiched between a plurality of

members

104A and 104B constituting the rod 104.
The seal member 105 expands and contracts as the rod 104 moves up and down by driving the air cylinder 50.

In the filling valve 100 of the present embodiment, a rectifying unit 106 that converts the spiral flow of the beverage 31 that has flowed into the flow channel 102 from the liquid supply pipe 120 into a substantially vertically downward flow is provided above the rod 104. Is formed.
The rectifying unit 106 includes a plurality of recesses 107 formed on the outer peripheral surface of the rod 104 at intervals in the circumferential direction.
The rod 104 is formed with a taper portion 108 whose outer diameter gradually decreases from above to below the seal member 105. Each of the concave portions 107 has a vertically long shape that is long in the vertical direction, and is continuously formed in the vertical direction from a portion above the taper portion 108 to the taper portion 108.

On the other hand, at a position facing the taper portion 108 of the rod 104, a flow rate adjusting portion 109 is formed on the inner peripheral surface of the flow path 102 so that the inner diameter gradually decreases from the top to the bottom.
The concave portion 107 has a width dimension in the circumferential direction of the rod 104 so that the area of the throttle 110 formed between the rod 104 and the flow rate adjusting unit 109 changes when the rod 104 moves up and down as the air cylinder 50 is driven. The depth of the rod 104 in the radial direction varies depending on the position of the rod 104 in the vertical direction.

The liquid filling apparatus 03 described above fills the first container 3 with carbonated beverages by sequentially performing the following steps.
[Cleaning treatment]
First, in order to circulate the cleaning liquid in the flow path 102, a stationary cleaning cap 40 (hereinafter referred to as “CIP cap 40”) is attached to the tip of the filling valve 100. Since the CIP cap 40 seals the opening at the tip of the filling valve 100, the cleaning liquid is not discharged from the filling valve 100 to the outside.
The inside of the filling valve 100 is cleaned by flowing the cleaning liquid into the flow path 102 and circulating the cleaning liquid through the flow path 102. When the circulation of the predetermined cleaning liquid is finished, the CIP cap 40 is removed and the cleaning liquid is discharged to the outside. Thereafter, the cleaning liquid is washed away and air is blown to discharge the liquid remaining in the channel 102 to the outside.

[Pressure drain treatment]
Subsequently, a pressure drain process for filling the beverage 31 in the filling valve 100 is performed.
In the pressure drain process, first, the inside of the filling valve 100 is pressurized to discharge the air remaining in the cleaning process to the outside of the filling valve 100. Then, after the liquid valve 103 is closed, the beverage 31 is filled into the filling valve 100. The flow rate of the beverage 31 to the filling valve 100 is adjusted by the opening degree of the throttle 110.
When filling the inside of the filling valve 100 with the beverage 31, the flow path through which the beverage 31 passes through the throttle 110 is once narrowed, and thus a large number of bubbles are generated. The generated bubbles stagnate in the vicinity of the diaphragm 110.
The pressurized drain process is performed at a saturated vapor pressure corresponding to the carbon dioxide content of the beverage 31.

[Bubble removal processing]
After the pressure drain process, a bubble removal process is performed in order to remove the bubbles generated at the throttle 110. The bubble removal process is a characteristic part of this embodiment.
In the bubble removal process, first, the inside of the filling valve 100 is increased to a pressure for filling a beverage (hereinafter, filling pressure). Next, as shown in FIG. 3, the CIP cap 40 (closed body) used in the cleaning process is attached to the tip of the filling valve 100. If it does so, the opening part of the front-end | tip of the filling valve 100 will be obstruct | occluded with the CIP cap 40, and the inside of the filling valve 100 (flow path 102) will be sealed.
Then, the counter valve 35 is opened. Then, since the pressure in the gas phase in the liquid storage tank 30 and the pressure in the filling valve 100 become the same, the filling pressure is applied to the liquid valve 103 also from the CIP cap 40 side.
Subsequently, the liquid valve 103 is opened and maintained as it is for a predetermined time. When the liquid valve 103 is opened, the pressure applied to the beverage 31 from the gas phase of the liquid storage tank 30 is equal to the pressure applied from the CIP cap 40 side. That is, since the pressure applied from above to the beverage 31 is equal to the pressure applied from below, the bubbles move up the flow path 102 by their own buoyancy and move to the gas phase of the liquid storage tank 30. The time for which the liquid valve 103 is kept open, that is, the time for removing bubbles is different depending on the type of beverage. Therefore, the predetermined time can be set by holding in advance data that associates the time for removing bubbles with the type of beverage.
When the predetermined time has elapsed, the liquid valve 103 and the counter valve 35 are closed, and then the CIP cap 40 is removed. Then, the filling of the beverage 31 is started.

[Beverage filling process]
Prior to filling the beverage, the container 3 is attached to the tip of the filling valve 100. The counter valve 35 is opened to make the inside of the container 3 have the same pressure as the gas phase of the liquid storage tank 30. By setting the same pressure, it is possible to prevent bubbles from being formed when the beverage 31 is filled.
When the liquid valve 103 is opened again, the beverage 31 is filled into the container 3 via the filling nozzle 15.
The filling amount can be set in advance by a flow rate control unit (not shown) of the filling valve.

In the bubble removal process of the present embodiment, bubbles generated in the diaphragm 110 by the pressure drain process can be removed. Then, the beverage 31 can be filled into the container 3 without including the generated bubbles. Therefore, the container 3 can be filled with the set regular filling amount of the beverage 31.

Moreover, the bubble removal process according to the present embodiment is particularly effective when filling a carbonated beverage having a low sugar content. The size of the generated bubbles is affected by the sugar content, and the lower the sugar content, the larger the bubbles. However, since the large bubbles are difficult to dissolve in the beverage 31, they remain as they are.

Furthermore, since the CIP cap 40 attached to the liquid filling device 03 is used in the bubble removal process of this embodiment, it is not necessary to add a new member. Therefore, the bubble removal process can be performed by the existing liquid filling apparatus 03.

[Second Embodiment]
In 1st Embodiment, the method of removing a bubble was demonstrated by using the CIP cap 40 after a pressure drain process.
In the present embodiment, bubbles generated in the throttle 110 are removed by adjusting the opening of the throttle 110 (the opening of the liquid valve 103).

Hereinafter, the beverage filling method in the present embodiment will be described. Processing similar to that of the first embodiment will be described briefly, and differences will be mainly described.
[Cleaning treatment]
A CIP cap 40 is attached to the tip of the filling valve 100, and the flow path 102 is cleaned with a cleaning liquid. Then, the CIP cap 40 is removed, the cleaning liquid is washed away, and air is blown to discharge the liquid remaining in the flow path 102 to the outside.
[Pressure drain treatment]
As with the first embodiment, the pressurized drain pressurizes the inside of the filling valve 100 and discharges air remaining in the cleaning process to the outside of the filling valve 100. Then, the beverage is filled into the filling valve 100 (flow path 102) through the flow path 102. At this time, the liquid valve 103 is closed.

[Bubble removal processing]
Next, the bubble removal process, which is a characteristic part of the present embodiment, will be described with reference to FIG.
Since the liquid valve 103 is closed after the pressure drain process, the region R1 is also almost sealed. Therefore, the bubbles are stagnated between the tapered portion 108 and the flow path 102.
Here, the rod 104 is pulled upward by a predetermined distance, and the liquid valve 103 is opened. As a result, a gap P is formed in a region R2 between the flow rate adjusting portion 109 and the tapered portion 108. Bubbles rise in this gap P in the direction of arrow H due to buoyancy and move to the gas phase of the liquid storage tank 30. Therefore, the generated bubbles are removed from the diaphragm 110.
That is, by pulling up the rod 104 by a predetermined distance, a bubble passage is formed and the bubbles are removed.
And the state which pulled up the rod 104 is maintained for a predetermined time, and it transfers to a drink filling process.
The predetermined distance is a minimum distance through which bubbles can pass.

[Beverage filling process]
The container 3 is attached to the tip of the filling valve 100. The counter valve 35 is opened, and the inside of the container 3 is set to the same pressure as the gas phase of the liquid storage tank 30. Then, the beverage 31 is filled into the container 3 via the filling nozzle 15 by further increasing the opening of the liquid valve 103.

In the filling method of the present embodiment, in the bubble removal process, bubbles generated in the throttle 110 can be removed, so that the set regular filling amount of the beverage 31 can be filled into the container 3.
In this embodiment, bubbles can be removed only by adjusting the opening of the liquid valve 103 without using other members (for example, the CIP cap 40 in the first embodiment). If it does so, it is not necessary to wash | clean another member after complete | finishing drink filling. Therefore, it is possible to save labor.

[Third Embodiment]
In the said embodiment, the method of filling the drink 31 of the regular filling amount by performing bubble removal processing was demonstrated. In the present embodiment, a method of filling the regular filling amount of the beverage 31 without performing the bubble removing process will be described.

In the present embodiment, the beverage is filled by the following process. Note that processing similar to that in the above embodiment will be described briefly, and differences will be mainly described.
[Cleaning treatment]
A CIP cap 40 is attached to the tip of the filling nozzle 15 and the flow path 102 is cleaned with a cleaning liquid. The CIP cap 40 is removed, the cleaning liquid is washed away, and air is blown to discharge the liquid remaining in the flow path 102 to the outside.
[Pressure drain treatment]
As with the first embodiment, the pressurized drain pressurizes the inside of the filling valve 100 and discharges the air remaining in the cleaning process to the outside of the filling valve 100. Then, the beverage 31 is filled in the flow path 102. At this time, the liquid valve 103 is closed.

[Beverage filling process]
After the pressure drain, the container 3 is attached to the tip of the filling valve 100 and the beverage is filled through the filling nozzle 15. The beverage filling amount in the present embodiment is set based on a database.
For example, as shown in FIG. 5, a database of insufficient filling amounts is created for each type (A, B, C...) Of beverage 31 to be filled.
Therefore, when the operator determines the beverage 31 to be filled, the operator presses a button corresponding to the type in a filling amount control device (not shown) for determining the filling amount. If it does so, the drink 31 of the quantity which supplemented the insufficient filling quantity will be filled.
This underfill amount can be determined by several methods.
For example, since it is known that the volume of bubbles generated in the throttle 110 depends greatly on the content and sugar content of the carbon dioxide gas with respect to the beverage 31, the content of the carbon dioxide gas and the sugar content of the beverage 31 are measured in advance, The volume of bubbles, that is, the insufficient filling amount is calculated.
Further, after the weight of the empty container 3 is measured in advance, a predetermined amount of beverage 31 is filled, and the weight of the filled container 3 is measured. Then, an insufficient filling amount is calculated from the difference in weight.
The insufficient filling amount calculated in this way is stored in a database as a set value for each type of beverage. And the setting value of a database is set as a drink filling amount. By doing so, the container 3 is filled with a set filling amount, that is, a beverage 31 having a regular filling amount.

In the filling method of this embodiment, the volume of bubbles mixed in the container 3 is calculated in advance, and an amount corresponding to the volume is added to the regular filling amount for filling. If it does so, the filling amount which is insufficient by mixing of air bubbles can be supplemented, and the beverage 31 of the regular filling amount can be filled in the container 3.
Further, since the filling amount based on the database may be set as the set value, no other operation is required. Therefore, it does not take time for filling work.

The embodiment of the present invention has been described above. However, other than this, the configuration described in the above embodiment can be selected or changed to another configuration without departing from the gist of the present invention. It is.
For example, in the first embodiment, it is sufficient if the inside of the filling valve 100 can be sealed. Therefore, the effect of the present invention can be enjoyed by providing a member that can seal the tip of the filling valve 100 in addition to the CIP cap 40.
Moreover, in 3rd Embodiment, the insufficient filling amount can be calculated from the relationship between the bubble size and the temperature of the beverage 31 to be filled, and a database can be created.
