来のものと同様である。Although the filling valve 1 can be constructed in substantially the same manner as a conventional filling valve, in this embodiment, the cleaning cap is formed by forming the outer peripheral surface of a skirt wall 8 provided at the lower end of the outer cylinder 3 in a tapered shape. The opening and closing of the cleaning cap is facilitated, and the sealing performance when the cleaning cap is attached is improved.
That is, since the cleaning cap and the skirt wall are fitted with a conical surface, when pressure is applied to the space 27, the sealing member 21 is pushed upward, and the sealing performance is further improved due to the wedge effect of the conical surface. In the configuration of the illustrated filling valve, 22

に装着される。In the filling valve cleaning apparatus for a liquid filling machine according to the present embodiment configured as described above, the cleaning of the filling valve is performed as follows. In a normal state where the cleaning operation is not performed, the cleaning cap 2 is in the non-cleaning state shown in FIG. 1A and is located inside the filling machine, so that it does not hinder the filling operation. When the filling valves are to be cleaned after the filling operation is completed, the cylindrical cap opening / closing cam 10 is lowered by a cylinder device (not shown) from the state shown in FIG. The cap opening / closing bars 12 are simultaneously pushed down. As a result, the pinion 7 meshing with the rack 14 provided at the lower end of the cap opening / closing bar 12 rotates clockwise in FIG. 1B integrally with the cap rotation shaft 5, and the cleaning cap is also moved to the state shown in FIG. , The wall face 17 of the cleaning cap is fitted with the skirt wall 8 of the filling valve body, and the cleaning cap is

It is pressed against the tapered surface of the skirt wall 8 against the spring 18 to be immersed, and when it reaches the engagement recess 9, it is protruded by the spring 8 and engages with the engagement recess 9. At this time, since the sealing material 21 of the cleaning cap is also in close contact with the skirt wall 8, the cleaning cap completely closes the lower end of the skirt wall.

The cleaning liquid fills the space 27 below the pressing rubber 26 sealed with the cleaning cap, and circulates as shown by the arrow 30 in FIG. By continuing this state for a predetermined time, the filling valve can be cleaned well. In particular, in the present invention, the cleaning can be performed while the filling valve 1 is being moved up and down as in the case of performing the normal filling operation. Further, since the filling valve is securely closed by the cleaning cap, there is no possibility that the cleaning liquid leaks.

（ａ）に示す元の状態に復帰する。When the cleaning is completed, the actuator disposed at a predetermined position outside the circular orbit on which the filling valve 1 moves moves at a predetermined timing to move the working piece 20 of the cleaning cap attached to the filling valve passing through the position. By pressing the upper end, as shown in FIG. 2 (b), when the in-and-out piece 19 enters and disengages with the engaging recess by the leverage action, the cleaning cap is instantaneously moved by its own weight and spring force as shown in FIG.
The state returns to the original state shown in FIG.

Further, it is not necessary to provide an actuator for opening the cleaning cap for each filling valve, and only one actuator is provided for the entire filling machine. Of the cleaning cap can be released. Further, according to the present invention, when the cleaning cap is in the non-cleaning state, as shown in FIG. 1 (a), the opening is downward, so that the cleaning liquid attached to the inner surface of the cleaning cap is naturally discharged, and droplets are formed. It does not remain on the inner surface of the cleaning cap and can be kept in a good state after cleaning without providing a special drain mechanism. At the time of normal filling, as shown in FIG. 4, the cleaning cap is maintained in an open state by a spring force (not shown), so that there is no hindrance to the filling operation.

Further, the cleaning cap is engaged with the filling valve by the ratchet mechanism, so that the cleaning cap can be automatically attached and detached with one touch only by one actuator in total. The cleaning cap and the filling valve are fitted and sealed by a tapered surface, so that the sealing performance of the cleaning cap is improved, and leakage of the cleaning liquid during cleaning can be reliably prevented.

Since the opening is downward, the cleaning liquid adhering to the inner surface of the cleaning cap is naturally drained, no drops remain on the inner surface of the cleaning cap, and it can be maintained in a good condition after cleaning without providing a special drain mechanism. Can be. Then, at the time of normal filling, the cleaning cap is kept open inside, so that it does not hinder the filling operation.
