The operation of such a device will be described. In FIG. 1, when the bottle 15 is lifted by a bottle lifting device (not shown), the bottle mouth is guided by the conical surface at the lower end of the centering cup 60 and abuts on the seal member 63 to block the inside and outside air of the bottle, and further the bottle is closed. Centering cup 60 when 15 rises
Rises against the pressing force of the spring 62, and the bottle mouth holds the liquid introduction pipe 3
Ascend to a position higher than the lower end of 1. In this process, the air chamber 6
The volume of the 1a is reduced, the air pressure increases with the bottle in communication with the chamber. Next , the pusher 70 is actuated, the rod 71 pushes down the air conduit 40, the liquid outlet valve 41 moves downward from the liquid introducing pipe 31, and the liquid outlet 31a and the air inlet 40d simultaneously communicate with the inside of the bottle 15. The high pressure air in the bottle 15 will force this liquid into the filler bowl 20 if any liquid remains in the air conduit 40. When the air conduit 40 further descends , the step portion 40c moves to the liquid inlet valve 50.
Abutting against and pushing it down to open the liquid passage. Liquid introduction pipe 31
Since the lower end of the liquid outlet 31a is already open, the liquid in the filler bowl 20 entering from the liquid inlet 30a by gravity flow down into the bottle 15, air in the bottle 15 is replaced with liquid from the air inlet 40d It enters the air conduit 40 and is discharged into the air phase of the filler bowl 20 through the hole 40b.

This state is shown in FIG. When the liquid level in the bottle 15 reaches the lower surface of the liquid introducing pipe 31 , the liquid is supplied to the air conduit 4
Entered risen to within 0, it stops to reach the liquid surface within the filler bowl 20. Then , when the rod 71 of the pusher 70 is lifted, the air conduit 40 is pushed by the spring 43 and lifted together, and the liquid inlet valve 50 is closed and the inflow of liquid from the filler bowl 20 is stopped. Next, when the bottle 15 is lowered, the guide cylinder 61
Internal expanding the volume of the air chamber 61a is lowered the pressure in the bottle 15, the liquid in the air conduit 40 is sucked, and flows down into the bottle 15. Next, the air conduit 40 is further raised and the liquid outlet valve 41 is closed. The bottle 15 continues to descend and leaves the centering cup 60 to return to the initial state. Although the pusher 70 is attached to the top plate of the filler bowl 20 in this example, it is attached to the side plate of the filler bowl 20 as shown in FIG.
It is needless to say that the spring seat 40a can be moved up and down with a, and thereby the height of the filling device can be reduced. Since the filling liquid level is determined by the distance between the upper end of the bottle mouth and the lower end of the liquid introducing pipe when the bottle 15 rises , if the filler bowl 20 is moved up and down by a lifting mechanism (not shown), all filling valves will be opened at once. Can be adjusted.

Next , the operation at the time of circulating cleaning will be described with reference to FIG. The joint 82 of the cleaning liquid passage is connected to the cleaning liquid tank 91,
It is connected in advance to the liquid circuit that returns to the filler bowl 20 via the cleaning liquid pump 92. The bottom of the centering cup 60, fitted with a cleaning cap 95 hermetically using a pin 60b that is provided in the cup, opening the liquid inlet valve 50 and the liquid outlet valve 41 lowers the pusher over 70, the circulation washing circuit Therefore, the opening / closing valve 81 may be opened to start the cleaning liquid pump 92.

Thus, according to this device, the air conduit 40
The liquid that has entered the bottle 15 is sucked back into the bottle 15 by the negative pressure created by the lowering of the bottle 15 in the latter half of the filling process, and if the liquid remains in the air conduit 40, the bottle 15 will be filled earlier in the filling process.
Since the compressed air created by the rise of the air blows into the filler bowl 20 vigorously , the air conduit 40 is empty and has no resistance at the beginning of the downward flow filling by gravity, and the filling time is reduced. It can be shortened. Also <br/>, the cleaning liquid passage 80a for circulating cleaning, 80b are be built in the device a structural member, it is not necessary to connect a pipe to the cleaning cap 95, the valve closes the fluid passage 50,41
Since it opened with a pusher over 70 used during the filling,
