得るよう構威されている。Reference numeral 22 denotes a control panel having required operation buttons provided on the outside of the outer bulkhead 1, 23 on the inside of the inner bulkhead 9, and 24 near the intermediate box 11, respectively. Each of them is configured to communicate with the drive unit 19, electromagnetic clutch 14.16, etc., and to operate the drive unit 19, electromagnetic clutch 14.16, etc. by operating an operation button.
２５はベベルギア−１７の駆動軸２６に設けた検出器で
あって、該検出器２５は扉４，４′、ラッチ５，５′、
平衝弁６，６′の開閉作動を検出しそれを停止するよう

よう構成されている。25 is a detector provided on the drive shaft 26 of the bevel gear 17, and the detector 25 is connected to the doors 4, 4', the latches 5, 5',
It is configured to detect and stop the opening/closing operation of the balance valves 6, 6', to control the opening/closing speed, and to display an indicator.
即ち、第３図に示すように、モータ１９の運転と同時に
検出器２５よりパルスがカウンター３０に表示されるよ
うになっており、その数値が判別回路３１に送り込まれ
、その数値と平衝弁６，６′、ラッチ５，５′、扉４，
４′の設定基準値（設定器３２）が一致した際に出力信
号（扉開閉用、平衝弁、ラッチ、扉減速開閉信号）３３
が出されるよう構威しである。That is, as shown in FIG. 3, pulses from the detector 25 are displayed on the counter 30 at the same time as the motor 19 is operating, and the value is sent to the discrimination circuit 31, which compares the value with the balance valve. 6, 6', latch 5, 5', door 4,
Output signal (for door opening/closing, balance valve, latch, door deceleration opening/closing signal) 33 when the set reference value (setter 32) of 4' matches.
The plan is for the government to issue the following.
向上記速度制御の一例としては、扉４，４′、ラッチ５
，５′、平衝弁６゜６′作動時は速度を速くし、ＧＤ２
の大きい扉の開閉時のみ開閉速度を遅くする。As an example of the speed control mentioned above, the doors 4, 4', the latch 5
, 5', when the balance valve 6°6' is activated, increase the speed and set GD2.
Slows down the opening/closing speed only when opening/closing large doors.
ここで、扉４，４′の開閉を直線運動と仮定した場合、
ＧＤ’ ＝Ｗ（−￥−）′とπＮ
なる。Here, if we assume that the opening and closing of doors 4 and 4' are linear movements,
GD' = W(-¥-)' and πN.
よって重量Ｗが大きく、開閉速度■が速い場合はＧＤ２
（慣性力）が大きくなり、開閉時の制動トルクが大き
くなる。Therefore, if the weight W is large and the opening/closing speed ■ is fast, GD2
(inertia force) increases, and the braking torque when opening and closing increases.
又、電磁クラッチ１４．１６ランプ類は電源不能時（停

路が形成されている。In addition, the electromagnetic clutches 14 and 16 lamps are powered by a battery (not shown) or powered by a direct current source so that there is no problem in operation in the event of a power outage (power outage or other accident).
A road is formed.
図中２７はシェル本体、２８は中間ボックス支持ブラケ
ット、２９はメカニカルシール
次に作動について説明する。In the figure, 27 is a shell body, 28 is an intermediate box support bracket, and 29 is a mechanical seal.Next, the operation will be explained.
先ず、外側バルクヘッド１に設けられている制御盤２２
の前に立ち電源が入っていることを確認してから該制御
盤２２上の外側肩４開のボタンを押し、中間ボックス１
１に設けられている駆動装置１９を回転させる。First, the control panel 22 provided on the outer bulkhead 1
Stand in front of the box and confirm that the power is on, press the button on the outer shoulder 4 on the control panel 22, and then open the intermediate box 1.
1 is rotated.
この際駆動装置１９の回転と同時に内側伝達用電磁クラ
ッチ１６はＯＦＦとなり駆動装置１９の回転は伝達しな
い。At this time, the inner transmission electromagnetic clutch 16 is turned off at the same time as the drive device 19 rotates, and the rotation of the drive device 19 is not transmitted.
駆動装置１９はカップリング１８、軸２６、ベベルギア
−１７、ベベルギア−１２を回転させ、更にその回転力
は外側伝達用電磁クラッチ１４、伝達軸３を経て外側メ
カニカルボックス８内のメカニカル機構７に伝達され、
各作動（平衝弁６開、ラッチ５開、扉４開）を行い検出
器２５の指令により所要の開作動が終了する。The drive device 19 rotates the coupling 18, shaft 26, bevel gear 17, and bevel gear 12, and further transmits the rotational force to the mechanical mechanism 7 in the outer mechanical box 8 via the outer transmission electromagnetic clutch 14 and the transmission shaft 3. is,
Each operation (balance valve 6 open, latch 5 open, door 4 open) is performed, and the required opening operation is completed by the command from the detector 25.
外側作動が終了（外側層４開）したら、次にエアロツク
部１０内に入り制御盤２４の前に立ち外側層４閉のボタ
ンを押すことにより開方向と全く逆の作動を行い閉の所
定位置にて停止終了する。When the outer operation is completed (the outer layer 4 is open), enter the airlock section 10, stand in front of the control panel 24, and press the outer layer 4 close button to perform the operation in the complete opposite direction to the opening direction and move it to the predetermined closed position. Stop and end at .
この二つの操作で扉４の開閉作動は完了する。These two operations complete the opening/closing operation of the door 4.
尚上記の場合、特に扉４は重量が重く、しかもマス（面
積）が大きい構造のため、開閉速度によっては扉４自体
の慣性力が大きくなり閉時の制御トルクが大きくなるの
で、駆動馬力に影響を及ぼす虞れがある。In the above case, the door 4 is particularly heavy and has a large mass (area) structure, so depending on the opening/closing speed, the inertia of the door 4 itself increases and the control torque when closing increases, so the drive horsepower There is a risk that it may have an impact.
そのため扉４の開閉時のみ（扉４の場合も同様）開閉速
度を遅くするとか、或いは開終了前又は閉終了前に制動
して速度を落すと言うような方法でも、その作動点の設
定数値を検出器２５で検出し信号処理することにより、
容易に速度制御が可能となる。Therefore, even if the opening/closing speed is slowed down only when opening/closing door 4 (the same applies to door 4), or the speed is reduced by braking before the opening or closing is completed, the set value of the operating point may be changed. By detecting with the detector 25 and processing the signal,
Speed control becomes possible easily.
又作動点の設定数値（設定器３２）を変えることにより
、希望の作動点で表示又は速度制御ができるため、正確
で安全な作動ができる。In addition, by changing the set value of the operating point (setter 32), display or speed control can be performed at the desired operating point, allowing accurate and safe operation.
以上のことよりエアロツク扉の開閉方式として、原子力
機器としての気密、圧力保持の関係から必ず外側層４開
→閉、次に内側扉４′開→閉が基本となっている。From the above, the basic opening/closing method for the airlock door is to always open and close the outer layer 4, and then open and close the inner door 4', in order to maintain airtightness and pressure in nuclear equipment.
当然のことながら炉内より外側に出る時は内側扉４′開
→閉、外側層４開→閉となる。Naturally, when exiting from inside the furnace, the inner door 4' opens and closes, and the outer layer 4 opens and closes.
又、これらのことより内、外扉４，４′のインターロッ
クが必要であり、本考案においては、電磁クラッチ１４
．１６及び電気的なインターロックとして、内外どちら
かの作動中の時に他の操作（押しボタン等を押す）をし
ても作動しないインターロック回路を組込んでいること
は云うまでもない。Moreover, for these reasons, it is necessary to interlock the inner and outer doors 4, 4', and in this invention, the electromagnetic clutch 14
．． 16 and as an electrical interlock, it goes without saying that an interlock circuit is incorporated which will not activate even if other operations (pressing a push button, etc.) are performed while either the inside or outside is in operation.
内側扉４′の開閉も制御盤２４の内側扉４′開のボタン
を押すことにより外側層４と同様な作動を行い開き、次
いで炉内側に入り制御盤２３の前に立ち内側扉４′閉の
ボタンを押し閉じる。The inner door 4' can be opened and closed by pressing the inner door 4' open button on the control panel 24, which operates in the same way as the outer layer 4. Next, enter the furnace, stand in front of the control panel 23, and close the inner door 4'. Press the button to close.
又、炉内より外側に出る時は、上記穴る時の逆の方式、
即ち制御盤２３にて内側扉４′開→制御盤２４にて内側
扉４′閉→制御盤２４にて外側層４開→制御盤２２にて
外側層４閉、の順にて完了する。Also, when going outside from the inside of the furnace, use the reverse method for making holes as described above.
That is, the control panel 23 opens the inner door 4', the control panel 24 closes the inner door 4', the control panel 24 opens the outer layer 4, and the control panel 22 closes the outer layer 4.
通常の開閉作動の場合は以上のような操作により円滑に
自動開閉ができ、且つ駆動部が一つのため中間ボックス
１１回りがコンパクトとなり、又開閉速度もコントロー
ルできるので操作上のトラブルは発生しない。In the case of normal opening/closing operation, automatic opening/closing can be performed smoothly by the above operations, and since there is only one driving part, the area around the intermediate box 11 is compact, and the opening/closing speed can be controlled, so no operational trouble occurs.
更に、停電、その他の事故等により電源不能時になった
時は、電源ＣＵＴ ＯＦＦと同時に図示しないバッテ
リー又は直流電流に切換えられ、内、外用電磁クラッチ
１６．１４及びランプ類は作動可能となり、駆動装置１
９以外はすべて通常の自動開閉操作と同じく行える。Furthermore, in the event of a power outage due to a power outage or other accident, the power is cut off and switched to a battery (not shown) or direct current, and the internal and external electromagnetic clutches 16 and 14 and lamps become operable, and the drive unit 1
All operations other than 9 can be performed in the same way as normal automatic opening/closing operations.
但し、開閉操作のみは駆動装置１９が回転しないので各
部備え付けのバンドル２、２０．２’を夫々回すことに
より扉４，４′の開閉は可能となる。However, since the drive device 19 does not rotate for opening/closing operations, the doors 4, 4' can be opened and closed by turning the bundles 2, 20.2' attached to each part, respectively.
尚、本考案はエアロツク扉の開閉用の他、類似の気密場
所等にも採用し得ること、その他本考案の要旨を逸脱し
ない範囲内において種々変更を加え得るものである。It should be noted that the present invention can be used not only for opening and closing airlock doors, but also for similar airtight places, and can be modified in various ways without departing from the gist of the present invention.
