充填を開始する前、充填液供給口２から流入した充填液ａは、内筒３の内部を通路とし
、内筒３の底部にある孔部１５より、内筒３に流入した充填液が外筒４内部下部に供給される。充填液供給口２から流入する充填液ａに流動圧力を加えなく、したがって外筒４下部内部に入る充填液ａの流動圧力が無ければ、内筒３に接続された開閉弁８が吐出孔１０上部に当接して吐出孔１０を閉鎖し、充填は行われない。
（充填動作）
充填液供給口２から流入する充填液ａに流動圧力を加え外筒４内部下部に入る充填液ａの流動圧力をかけると、内筒３に対して外筒４を下方に向かわせる力が働き内筒３に対して外筒４が下降し、スプリング９は縮み、開閉弁８が吐出孔１０上部から離反して吐出孔１０を開口し、充填液ａの被充填容器３０への充填が行われる。
（充填停止）
さらに、充填停止を行おうとすれば、充填開始前と同じように、充填液供給口２から流入した充填液ａの流動圧力をなくせば、スプリング９のもとの長さに戻ろうとする力により、内筒３に対して外筒４は上に向かう力が働き、開閉弁８が吐出孔１０上部に当接して吐出孔１０を閉鎖し、充填は行われない。 The filling liquid a supplied from the filling liquid feeding section passes through the filling liquid supply port 2, passes through the inside of the inner cylinder 3, and enters the inside of the lower part of the outer cylinder 4 through the hole 15 at the bottom of the inner cylinder 3.

It is supplied to the inside lower part of the cylinder 4. If no flow pressure is applied to the filling liquid a flowing in from the filling liquid supply port 2, and therefore there is no flow pressure of the filling liquid a entering the lower part of the outer cylinder 4, the on-off valve 8 connected to the inner cylinder 3 is connected to the discharge hole 10. The discharge hole 10 is closed in contact with the upper portion, and no filling is performed.
(Filling operation)
When a flow pressure is applied to the filling liquid a flowing in from the filling liquid supply port 2 and a flow pressure of the filling liquid a entering the lower part inside the outer cylinder 4 is applied, a force that moves the outer cylinder 4 downward with respect to the inner cylinder 3 works. The outer cylinder 4 is lowered with respect to the inner cylinder 3, the spring 9 is contracted, the on-off valve 8 is separated from the upper part of the discharge hole 10 to open the discharge hole 10, and the filling liquid 30 is filled with the filling liquid a. Is called.
(Stop filling)
Furthermore, if the filling is stopped, the flow pressure of the filling liquid a flowing in from the filling liquid supply port 2 is eliminated as in the case before the filling is started. The outer cylinder 4 exerts an upward force with respect to the inner cylinder 3, the on-off valve 8 abuts on the upper part of the discharge hole 10 to close the discharge hole 10, and no filling is performed.

このように充填液圧送部によって充填液供給口２から流入した充填液ａに流動圧力を加えないか、加えるかを行い、吐出・非吐出を制御できる充填制御機構を有する。   In this way, the filling liquid pumping unit has a filling control mechanism capable of controlling whether or not to apply the flow pressure to the filling liquid a flowing in from the filling liquid supply port 2 and controlling discharge / non-discharge.

スプリング９は、充填停止時に、内筒３に対して外筒が上に上昇し、内筒３に接続された開閉弁８が吐出孔１０上部に当接して吐出孔１０を閉鎖したときの、外筒の上下位置で、伸縮がない状態になるよう設置する。   When the filling is stopped, the spring 9 rises upward with respect to the inner cylinder 3, and the on-off valve 8 connected to the inner cylinder 3 abuts on the upper part of the discharge hole 10 to close the discharge hole 10. Install so that there is no expansion and contraction at the vertical position of the outer cylinder.

ねじ１３は、シャフト上端部に固定する座金でもよい。   The screw 13 may be a washer that is fixed to the upper end of the shaft.

充填液供給口２には、充填液ａを供給し、充填液供給口２に流入する充填液ａに流動圧力を加えない、加えることを選択的に行える充填液圧送部（不図示）が接続されている。   Connected to the filling liquid supply port 2 is a filling liquid pumping section (not shown) that supplies the filling liquid a and does not apply the flow pressure to the filling liquid a flowing into the filling liquid supply port 2 but can selectively apply the filling pressure. Has been.

充填液圧送部から供給された充填液ａは充填液供給口２を通り、内筒３の内部を通り、
内筒３の底部にある孔部１５より、外筒４下部内部に入る。
（充填開始前）
充填を開始する前、充填液供給口２から流入した充填液ａは、内筒３の内部を通路とし、内筒３の底部にある孔部１５より、内筒３に流入した充填液が外筒４内部下部に供給される。充填液供給口２から流入する充填液ａに流動圧力を加えなく、したがって外筒４下部内部に入る充填液ａの流動圧力が無ければ、内筒３に接続された開閉弁８が吐出孔１０上部に当接して吐出孔１０を閉鎖し、充填は行われない。
（充填動作）
充填液供給口２から流入する充填液ａに流動圧力を加え外筒４内部下部に入る充填液ａの流動圧力をかけると、内筒３に対して外筒４を下方に向かわせる力が働き内筒３に対して外筒４が下降し、スプリング９は伸び、開閉弁８が吐出孔１０上部から離反して吐出孔１０を開口し、充填液ａの被充填容器３０への充填が行われる。
（充填停止）
さらに、充填停止を行おうとすれば、充填開始前と同じように、充填液供給口２から流入した充填液ａの流動圧力をなくせば、スプリング９のもとの長さに戻ろうとする力により、内筒３に対して外筒４は上に向かう力が働き、開閉弁８が吐出孔１０上部に当接して吐出孔１０を閉鎖し、充填は行われない。 The filling liquid a supplied from the filling liquid pumping section passes through the filling liquid supply port 2, passes through the inside of the inner cylinder 3,
It enters the lower part of the outer cylinder 4 through the hole 15 at the bottom of the inner cylinder 3.
(Before starting filling)
Before the filling is started, the filling liquid a flowing in from the filling liquid supply port 2 passes through the inside of the inner cylinder 3 through the hole 15 at the bottom of the inner cylinder 3, and the filling liquid flowing into the inner cylinder 3 is discharged outside. It is supplied to the inside lower part of the cylinder 4. If no flow pressure is applied to the filling liquid a flowing in from the filling liquid supply port 2, and therefore there is no flow pressure of the filling liquid a entering the lower part of the outer cylinder 4, the on-off valve 8 connected to the inner cylinder 3 is connected to the discharge hole 10. The discharge hole 10 is closed in contact with the upper portion, and no filling is performed.
(Filling operation)
When a flow pressure is applied to the filling liquid a flowing in from the filling liquid supply port 2 and a flow pressure of the filling liquid a entering the lower part inside the outer cylinder 4 is applied, a force that moves the outer cylinder 4 downward with respect to the inner cylinder 3 works. The outer cylinder 4 is lowered with respect to the inner cylinder 3, the spring 9 is extended, the on-off valve 8 is separated from the upper part of the discharge hole 10 to open the discharge hole 10, and the filling liquid 30 is filled with the filling liquid a.

The outer cylinder 4 exerts an upward force with respect to the inner cylinder 3, the on-off valve 8 abuts on the upper part of the discharge hole 10 to close the discharge hole 10, and no filling is performed.

このように充填液圧送部によって充填液供給口２から流入した充填液ａに流動圧力を加えないか、加えるかを行い、吐出・非吐出を制御できる充填制御機構を有する。   In this way, the filling liquid pumping unit has a filling control mechanism capable of controlling whether or not to apply the flow pressure to the filling liquid a flowing in from the filling liquid supply port 2 and controlling discharge / non-discharge.

本発明の液体充填ノズル装置により、構造が簡単で安価な液体充填ができるようになった。   The liquid filling nozzle device of the present invention has a simple structure and can be filled with an inexpensive liquid.

従来の充填ノズル装置において、アクチュエータとしてエアーシリンダーを採用した場合、エアーや電気のユーティリティが必要であったが、本発明の液体充填ノズル装置では不要である。   In the conventional filling nozzle device, when an air cylinder is employed as an actuator, utility of air or electricity is required, but is not necessary in the liquid filling nozzle device of the present invention.

また、構造が簡単であるため、装置の設置時の組み付けや、メインテナンス時の分解時において、処置が簡便である。   Further, since the structure is simple, the treatment is simple at the time of assembling at the time of installation of the apparatus and at the time of disassembly at the time of maintenance.

また、充填時、先端ノズルが下降するので、被充填容器に先端ノズルを近づけることが可能なため、液の飛散を抑制し、充填効率を向上することができる。   In addition, since the tip nozzle is lowered during filling, the tip nozzle can be brought close to the container to be filled, so that scattering of liquid can be suppressed and filling efficiency can be improved.

前記スプリングは前記外筒内部下部に入る充填液の流動圧力をかけると内筒に対して外筒を下降させて前記開閉弁から前記吐出孔上部が離反して前記吐出孔を開口させ、前記外筒下部内部に入る充填液の流動圧力が無ければ前記内筒に対して前記外筒は上昇し前記開閉弁が吐出孔上部に当接して前記吐出孔を閉鎖するものであることを特徴とする液体充填ノズル装置。 A liquid filling nozzle device for injecting liquid into a container,
An inner cylinder that continues from the filling liquid supply port and serves as a passage for the filling liquid, an on-off valve formed at the bottom of the bottom of the inner cylinder, and an outer fitting that is slidably fitted in the inner cylinder so as to be slidable in the vertical direction It is composed of a cylinder and a discharge hole formed in the lower end portion of the outer cylinder,
A hole provided at the bottom of the inner cylinder for supplying a filling liquid of the inner cylinder to the lower part inside the outer cylinder;
A spring for supporting the outer cylinder with respect to the inner cylinder;
When the flow pressure of the filling liquid entering the lower part inside the outer cylinder is applied to the spring, the outer cylinder is lowered with respect to the inner cylinder, the upper part of the discharge hole is separated from the on-off valve, and the discharge hole is opened. If there is no flow pressure of the filling liquid entering the inside of the lower part of the cylinder, the outer cylinder rises with respect to the inner cylinder, and the on-off valve contacts the upper part of the discharge hole to close the discharge hole. Liquid filling nozzle device.
