In correspondence with this filling valve 92, a large number of container stands 94 that are moved up and down by a lifter 93 are provided below the filling valve 92 when the shape or liquid type of the container 95 for filling the liquid is changed. Each time, it was replaced according to the container 95, and this work was performed manually one by one.

However, the filling valve 91 itself has a heavy weight, and a large number of replacements thereof are troublesome because the workability is poor for a long time, and a heavy labor burden is imposed on the worker. In the work immediately after cleaning and sterilization, since the temperature of the entire valve is high, it is easy to drop it, and there is a problem that the expensive tip nozzle of the filling valve 91 is damaged.

On the other hand, for example, this filling valve 91
Screw to the mounting part 96 of the liquid tank 91 as shown in FIG.
Since it was attached by 97, in order to attach and detach the filling valve 92, it is necessary to screw the valve 92 many times, and since it is heavy in itself, many replacements thereof are not workable for a long time. Not only is it bad and troublesome, but it also puts a heavy burden on workers.

Further, the screw-in type requires a large force at the beginning of the removal and the end of the fastening of the filling valve, which requires a great deal of work and is wet, and the temperature of the entire valve becomes high immediately after cleaning and sterilization. If this happens, this task becomes even more difficult.

Further, in the screw-in type, since the corresponding position between the liquid level in the container and the tip of the filling valve is changed depending on the screw-in amount, the filling cannot be performed with high precision, and the detaching / attaching is not possible. Each of them must be manually operated, and the purpose of fully automating the filling line cannot be achieved. There were various problems such as.
