DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. First, based on FIG. 1, a general image of the desorption device for a filling valve according to the present invention will be outlined.

Reference numeral 1 is a filling valve for filling the filling liquid in the container 2, and a plurality of filling valves are arranged at equal intervals on the same circumference of the bottom surface of the filling liquid tank 3. Each filling valve 1 has an upper portion fitted into a hole 3a formed in the bottom surface of the filling liquid tank 3,
The upper surface of the flange portion 4 provided on the outer periphery is brought into contact with the bottom surface of the filling liquid tank 3.

The flange portion 4 of each filling valve 1 is disposed between the filling valves 1 and 1, and is supported by a mounting member 5 so as to engage with the lower surface of the flange portion 4. The mounting member 5 supporting this filling valve 1 is
As can be understood from FIG. 2, when the fluid pressure is discharged, the biasing force in the direction of supporting by the spring 14 always works and is fixed. Then, each mounting member 5 is moved up and down by the fluid pressure cylinder 6, and the filling liquid tank 3 is moved.
Is configured to come into contact with and separate from the bottom surface of the.

Each of the filling valves 1 has a conventionally well-known structure, and includes a liquid injection pipe 7 for filling the container 2 with the filling liquid,
An exhaust pipe 8 for discharging the air in the container 2 being filled is provided. When the container 2 is lifted by a lifting table (not shown), the upper end opening is centered by the guide cone 9 and abuts the bottle packing 10, the inside of the container 2 is sealed, and when the container 2 is further lifted, the liquid injection pipe The lower end of 7 separates from the valve seat 11.

As a result, the filling liquid is filled in the container 2 via the liquid injection pipe 7, and the air in the container 2 is discharged to the outside via the exhaust pipe 8 and then the filling in the container 2 is completed. When the liquid closes the lower end opening of the exhaust pipe 8, the filling of the filling liquid from the liquid injection pipe 7 automatically stops. Then, the container 2 descends and the lower end of the liquid injection pipe 7 is seated on the valve seat 11, and the filling of the filling liquid into the container 2 is completed.

In this way, when the filling operation is completed and it becomes necessary to clean the filling valve 1 or replace the filling valve 1 itself, a fluid pressure source (not shown).
More fluid pressure through the fluid pressure manifold 12 to the hose 1
3 to the respective clamping fluid pressure cylinders 6 provided in engagement with the respective filling valves 1, and by this pressure, the mounting member 5 is pushed down against the springs 14 and the respective filling valves 1
It can be removed by releasing the clamped flange portion 4 of the above, rotating the filling valve 1 by 90 ° and pulling it downward.

Next, the filling valve attaching / detaching device of the present invention will be described in detail with reference to FIGS. 2 and 3.

First, as shown in an enlarged manner in FIG. 3, the mounting member 5 is formed in a substantially elliptical shape so that the outer peripheral portion of the upper surface thereof always engages with the flange portion 4 of the filling valve 1, and the other flange. A pair of escape portions 4a that do not engage with the mounting member 5 are formed on the outer periphery of the portion 4.

With the above-mentioned structure, the filling valve 1 is normally attached to the fluid pressure cylinder 6 by a substantially elliptical attachment member 5 provided by appropriate means in a positional relationship as shown in FIG.

In this mounting, as shown in FIG. 2, a piston member 16 having a fluid pressure injection hole 15 supplied from a fluid pressure source is fixed to the bottom surface of the filling liquid tank 3. The fluid pressure cylinder 6 is provided so as to surround the piston member 16, and the piston member 16 and the fluid pressure cylinder 6 are combined so as to form a space 17 therebetween. Then, the injection hole 15 is opened in the empty chamber 17. Furthermore, a sealed state is maintained between the piston member 16 and the fluid pressure cylinder 6 via a packing 18, and the fluid pressure cylinder 6 can be moved up and down with the piston member 16 as a guide.

The fluid pressure cylinder 6 moves up and down by controlling the supply and discharge of fluid pressure with the piston member 16 as a guide. This is due to the lower end surface of the fluid pressure cylinder 6 and a spring receiver fixed to the tip of the piston member 16. A spring 14 is arranged between 19 to apply a biasing force so that the fluid pressure cylinder 6 is constantly pressed against the filling liquid tank 3 side, and is attached via a piston member 16. When the fluid pressure is supplied against the spring 14, the fluid pressure cylinder 6 is pushed down. For this purpose, the fluid pressure cylinder 6
Since the mounting member 5 fixed to is also pushed down in the direction of the arrow, the mounting member 5 pressing the flange portion 4 of the filling valve 1 is lowered and the flange portion 4 becomes free. Therefore, the filling valve 1 can be removed by rotating the filling valve 1 to the escape portion 4a shown in FIG. 3 and pulling it downward.

In the above construction, when the filling valve 1 is attached to the bottom surface of the filling liquid tank 3, it is possible to carry out the reverse operation to the removal. First, a fluid pressure is supplied to lower the mounting member 5 fixed to the fluid pressure cylinder 6, and the relief valve 4a of the flange portion 4 of the filling valve 1 is placed on the mounting member 5 side. 1 is fitted to the bottom surface of the filling liquid tank 3.

Next, the filling valve 1 is rotated 90 °, and a portion of the flange portion 4 without the relief portion 4a (in other words, a portion that can be engaged) is directed to the mounting member 5 and temporarily fixed.

By discharging the fluid pressure in this state, the fluid pressure cylinder 6 is raised by the pushing force of the spring 14 to guide the piston member 16, and as a result, the mounting member 5 fixed to the fluid pressure cylinder 6 is raised. Then, the flange portion 4 of the filling valve 1 is pressed and fixed to the bottom surface of the filling liquid tank 3.

The fluid pressure supply / discharge to / from the fluid pressure cylinder is
It can be designed by selecting either automatic control or manual control.

[0021]

As a result of adopting the above configuration, the present invention provides
The following effects can be obtained. (1) The filling valve can be attached and detached very easily, and the time can be shortened. (2) Conventionally, it was necessary to individually attach and detach each filling valve. On the other hand, the desorption device of the present invention can create the desorption state for each filling valve at once by using the fluid pressure manifold.
