Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a mounting device for mounting a filling valve to a filling liquid tank.

``Prior Art'' Conventionally, as a filling device for filling a container with a filling liquid, a filling valve provided at the bottom of a filling liquid tank that stores the filling liquid and a flange portion provided on the filling valve are engaged from below. a rectangular plate-shaped mounting member, and a tightening bolt for fixing the mounting member to the filling liquid tank; It is known that the filling valve is fixed to the filling liquid tank by engaging with the filling valve.

In such a filling device, when attaching the filling valve to the bottom of the filling liquid tank, first temporarily fasten the mounting member to the filling liquid tank with a tightening bolt and at the same time rotate it to a position where it does not engage with the flange of the filling valve. Then, the flange portion of the filling valve is passed through the mounting member so that its upper surface is brought into contact with the lower surface of the filling liquid tank. Next, the mounting member is rotated to engage the lower surface of the flange of the filling valve, and in this state, the mounting member is fixed to the bottom surface of the filling liquid tank with a tightening bolt.
The filling valve was fixed to the bottom of the filling liquid tank.

``Problem that the invention aims to solve'' However, as mentioned above, conventionally, the mounting member was formed into a rectangular plate shape, so when tightening the tightening bolt, the mounting member easily rotated. The tip of the bolt will come off the engaged flange and the filling valve will no longer be supported, so when tightening the tightening bolt, it is necessary to hold the mounting member so that it always engages with the flange, resulting in poor installation workability and Ta.

"Means for Solving the Problem" In view of such circumstances, in the present invention, the mounting member is formed into a substantially disk shape, and the entire outer circumference thereof can be engaged with the flange portion, and A relief portion that does not engage with the mounting member is formed in the flange portion.

"Operation" According to such a configuration, even if the mounting member rotates as the tightening bolt is tightened during the filling valve installation work, if the filling valve does not rotate, the flange portion and the mounting member will not rotate. It is always in an engaged state. Therefore, when installing the filling valve, it is only necessary to prevent the filling valve side from rotating, which simplifies the filling valve installation work compared to the conventional method of preventing rotation of the mounting member. You will be able to do this.

"Example" The present invention will be explained below with reference to the illustrated example.
In FIG. 3, reference numeral 1 denotes a filling valve for filling the container 2 with the filling liquid, and a plurality of them are arranged at equal intervals on the same circumference on the bottom surface of the filling liquid tank 3. The upper portion of each filling valve 1 is fitted into a hole 3a formed in the bottom of the filling liquid tank 3, and the upper surface of a flange portion 4 provided on the outer periphery is brought into contact with the bottom of the filling liquid tank 3.

The flange portion 4 of each filling valve 1 is supported by a mounting member 5 that is disposed between each filling valve 1 and engages with the lower surface of the flange portion 4, and each mounting member 5 is Tightening bolt 6
It is fixed to the bottom surface of the filling liquid tank 3 by.

Each of the above-mentioned filling valves 1 has a conventionally well-known configuration, and has a liquid filling pipe 7 for filling the container 2 with filling liquid.
and an exhaust pipe 8 for discharging the air inside the container 2 during filling.
It is equipped with Then, the container 2 is lifted up by a lifting table (not shown), and when its upper end opening is centered by the guide cone 9 and comes into contact with the bottle opening packing 10, the inside of the container 2 is sealed, and the container 2 is further lifted up. and the lower end of the liquid injection pipe 7 is the valve seat 1.
Leave from 1.

As a result, the filling liquid is filled into the container 2 via the liquid filling pipe 7, and the air inside the container 2 is discharged to the outside via the exhaust pipe 8, and the filling liquid filled in the container 2 is eventually exhausted. When the lower end opening of the tube 8 is closed, filling of the filling liquid from the liquid injection tube 7 is automatically stopped. Thereafter, the container 2 is lowered so that the lower end of the liquid injection pipe 7 is seated on the valve seat 11, and the filling of the liquid into the container 2 is completed.

As shown in FIGS. 1 and 2 on an enlarged scale, the mounting member 5 is formed into a disk shape so that the outer peripheral portion of the upper surface always engages with the flange portion 4. A pair of relief portions 4a that do not engage with the mounting member 5 are formed on the outer periphery of the portion 4.
In addition, the tightening bolt 6 for attaching the mounting member 5 to the bottom of the filling liquid tank 3 is the mounting member 5 in this embodiment.
A stud bolt 1 is screwed into the bottom of the filling liquid tank 3 by passing through a hole 5a bored in the center of the tank.
2, a nut 13 screwed onto the stud bolt 12 from below the mounting member 5, and a stopper ring 14 attached to the lower end of the stud bolt 12 to prevent the nut 13 from falling off. ing.

In the above configuration, when the filling valve 1 is to be attached to the bottom of the filling liquid tank 3, the mounting member 5 is first temporarily fixed to the bottom of the filling liquid tank 3 with a tightening bolt 6. Next, rotate the filling valve 1 to direct the relief part 4a of the flange part 4 toward the mounting member 5,
In this state, lift the filling valve 1 and fit the upper part of the filling valve 1 into the hole 3a of the filling liquid tank 3,
Furthermore, the flange portion 4 is passed through the mounting member 5 and brought into contact with the bottom surface of the filling liquid tank 3. Then, when the entire filling valve 1 is rotated 90 degrees, the lower surface of the flange portion 4 engages with the outer circumference of the upper surface of the mounting member 5, so that the mounting member 5 prevents the filling valve 1 from falling. It becomes like this.

Once this condition is reached, the filling valve 1 can be fixed to the bottom of the filling liquid tank 3 by tightening the nut 13 of the tightening bolt 6. At this time, hold the filling valve 1 so that it does not rotate. If so, even if the mounting member 5 rotates as the nut 13 is tightened, the outer periphery of the mounting member 5 will always be engaged with the flange portion 4, so the filling valve 1 will not fall. , the tightening work can be performed easily and safely.

In this way, in this embodiment, since it is only necessary to hold the filling valve 1 so that it does not rotate when tightening the tightening bolt 6, the work is easier than in the case where the mounting member 5 is held so that it does not rotate as in the conventional case. can be made easier.

Conversely, when removing the filling valve 1 from the bottom of the filling liquid tank 3, loosen the tightening bolts 6 a little and then rotate the entire filling valve 1 by 90 degrees, so that the flange portion 4 and the mounting member 5 are separated. The filling valve 1 can be easily disengaged by the relief part 4a.
can be removed from the bottom of the tank 3.

Further, the mounting member 5 may be formed into a substantially disk shape, that is, it may be formed so as to always engage with the flange portion 4 even when the mounting member 5 rotates, and may be formed into a complete circle. Of course, it is not necessary to use a board.

"Effects of the Invention" As described above, the present invention has the effect that the work of attaching and detaching the filling valve to the filling liquid tank can be simplified compared to the conventional method.
