In the following description, similar elements are denoted by the same reference numerals, and redundant description is omitted.

（１）本実施の形態によるエレベータ装置の構成
図１は、本発明の一実施の形態に係るエレベータ装置１００について示す図である。この図に示されるように、エレベータ装置１００は、乗りかご１０４と、乗りかご１０４の昇降を行う巻上機１４４と、乗りかご１０４が接続されたロープの他端に接続されたカウンターウェイト１４６と、乗りかご１０４の状態や乗客の指令等を受信し、巻上機１４４の制御を行うエレベータ制御部１４２と、乗りかご１０４の出入り口で開閉を行う２枚のドアパネル１１０と、ドアパネル１１０を駆動するドアモータ１３０と、２枚のドアパネル１１０の前縁に配置され、戸閉じ時にドアパネル１１０に挟まれるものがあること検知する戸閉じ時安全障害検知部１１２と、ドアパネル１１０の開閉動作をドアモータ１３０に指示すると共に、戸閉じ時安全障害検知部１１２又は後述する戸開き時安全障害検知部１２４が作動した場合に、作動した旨を受信するドア制御部１２０と、を有している。 (1) Configuration of Elevator Device According to this Embodiment FIG. 1 is a diagram showing an elevator device 100 according to an embodiment of the present invention. As shown in this figure, the elevator apparatus 100 includes a car 104, a hoisting machine 144 that raises and lowers the car 104, a counterweight 146 connected to the other end of the rope to which the car 104 is connected, The elevator controller 142 that receives the state of the car 104, the passenger's command, etc., controls the hoisting machine 144, the two door panels 110 that open and close at the entrance and exit of the car 104, and drives the door panel 110 The door motor 130 is disposed on the front edge of the two door panels 110 and detects that there is something that is sandwiched between the door panels 110 when the door is closed, and the door motor 130 is instructed to open and close the door panel 110. When the door closing safety fault detection unit 112 or the door opening safety fault detection unit 124 described later is activated, It has a door control unit 120 for receiving the effect that the dynamic, the.

ここで、戸閉じ時安全障害検知部１１２は、例えばドアパネル１１０の前縁にリンク機構を介して突出設置され、物体との接触により、後退しつつ上方に変位するセイフティシューを用いたものとして構成されていてもよいし、ドアパネル１１０の前縁付近に設置されたレーザやタッチセンサ等その他のセンサにより構成されていてもよい。   Here, the door closing safety failure detection unit 112 is configured to use, for example, a safety shoe that protrudes from the front edge of the door panel 110 via a link mechanism and moves upward while retreating due to contact with an object. It may also be configured by other sensors such as a laser or a touch sensor installed near the front edge of the door panel 110.

図２は、本実施の形態に係るドア制御の構成を示すブロック図である。ドア制御部１２０は、戸開き時に戸袋に引き込まれるものがあることを検知する戸開き時安全障害検知部１２４を有している。戸開き時安全障害検知部１２４は、戸開き時に一定以上の負荷が加わったことをドアモータ１３０からのトルクフィードバック信号により検出する過負荷検出機能を有するものとすることができる。この場合には、過負荷検出は、モータトルク推定値とモータトルク指令とを比較し、その差分が所定値以上の場合に過負荷状態であると判定するものであってもよい。また、戸開き時安全障害検知部１２４は、過負荷検出でなくても、例えば、戸袋の入り口部に設置されたレーザやタッチセンサ等その他のセンサにより構成されていてもよい。この場合には、戸開き時安全障害検知部１２４は、図３に示されるように、ドア制御部１２０の外部装置として構成されることができる。   FIG. 2 is a block diagram illustrating a configuration of door control according to the present embodiment. The door control unit 120 includes a door opening safety fault detection unit 124 that detects that there is something that is pulled into the door pocket when the door is opened. The door-opening safety failure detection unit 124 may have an overload detection function that detects that a load of a certain level or more has been applied when the door is opened using a torque feedback signal from the door motor 130. In this case, the overload detection may be performed by comparing the estimated motor torque value with the motor torque command, and determining that the overload state is present when the difference is equal to or greater than a predetermined value. Further, the door opening safety fault detection unit 124 may be configured by other sensors such as a laser and a touch sensor installed at the entrance of the door pocket, for example, without detecting overload. In this case, the door opening safety fault detection unit 124 can be configured as an external device of the door control unit 120, as shown in FIG.

ドア制御部１２０は、戸閉じ時安全障害検知部１１２が作動した際に、その旨を受信し、通常時よりも低速での戸開き動作である安全障害検知時の戸開き動作を行うよう、ドアモータ１３０を制御する。また、戸開き時安全障害検知部１２４が作動した際にも、その旨を受信し、通常時よりも低速での戸閉じ動作である安全障害検知時の戸閉じ動作を行うよう、ドアモータ１３０を制御する。更に、安全障害検知時の戸開き動作中に戸開き時安全障害検知部１２４が作動した旨の信号を受信した場合には、安全障害検知時の戸閉じ動作を行うように、ドアモータ１３０を制御し、安全障害検知時の戸閉じ動作中に戸閉じ時安全障害検知部１１２が作動した場合には、安全障害検知時の戸開き動作を行うよう、ドアモータ１３０を制御する。   When the door closing safety fault detection unit 112 is activated, the door control unit 120 receives that fact and performs the door opening operation at the time of safety failure detection, which is a door opening operation at a lower speed than normal. The door motor 130 is controlled. Further, when the door opening safety fault detection unit 124 is activated, the door motor 130 is received so as to perform the door closing operation at the time of safety fault detection that is a door closing operation at a lower speed than normal. Control. Further, when the door opening operation at the time of safety failure detection receives a signal indicating that the door opening safety failure detection unit 124 is activated, the door motor 130 is controlled to perform the door closing operation at the time of safety failure detection. When the door-closing safety fault detection unit 112 is activated during the door-closing operation when the safety fault is detected, the door motor 130 is controlled to perform the door-opening operation when the safety fault is detected.

また、ドア制御部１２０は、戸閉じ時安全障害検知部１１２又は戸開き時安全障害検知部１２４が動作した回数をカウントする安全障害検知カウント部１２２を有し、安全障害検知カウント部１２２のカウント値が所定の閾値に達した時点で戸閉じ動作又は戸開き動作を完了させたり、ドアの開閉力を無効（トルク無し）としたり等のドア制御とすることができる。ドアの開閉力を無効とした場合には、ドアパネル１１０は手動で開閉可能となる。この際に非常停止状態とし、外部に異常を報知することとしてもよい。ここで、安全障害検知カウント部１２２を設けずに戸閉じ時安全障害検知部１１２又は戸開き時安全障害検知部１２４の作動により、常に安全障害検知時の動作を行わせることとしてもよい。ドア安全装置は、戸閉じ時安全障害検知部１１２、戸開き時安全障害検知部１２４、ドア制御部１２０、及びドア制御部１２０により制御されるドアモータ１３０により構成される。   In addition, the door control unit 120 includes a safety failure detection count unit 122 that counts the number of times that the door-closing safety failure detection unit 112 or the door-open safety failure detection unit 124 operates. When the value reaches a predetermined threshold, the door closing operation or the door opening operation is completed, or the door opening / closing force is disabled (no torque), or the door control can be performed. When the door opening / closing force is invalidated, the door panel 110 can be manually opened and closed. At this time, an emergency stop state may be set to notify the outside of the abnormality. Here, the safety failure detection count unit 122 is not provided, and the operation at the time of safety failure detection may be always performed by the operation of the safety failure detection unit 112 when the door is closed or the safety failure detection unit 124 when the door is opened. The door safety device includes a door closing safety fault detection unit 112, a door opening safety fault detection unit 124, a door control unit 120, and a door motor 130 controlled by the door control unit 120.

（２）ドア制御部によるドアパネルの制御
図４は、ドア制御部１２０の処理の例のシーケンス図である。この処理は、停止階における通常の開閉動作及び乗客による開閉指示による開閉動作が行われる際に実行される。図４に示されるように、ドア制御部１２０は、まず、戸閉じ時安全障害検知部１１２及び戸開き時安全障害検知部１２４が同時に作動したかどうかを確認する（ステップＳ１）。ここで、同時に作動している場合には、ドア制御部１２０はドアモータ１３０への電力供給を停止する等により、ドアの開閉力を無効（トルク無し）の状態とする（ステップＳ２１）。ドアの開閉力を無効とすることにより、ドアパネル１１０は手動で開閉可能となる。一方、同時に作動していない場合には、ステップＳ２に移行し、戸開き動作中であるかどうかを確認し、戸開き動作中である場合には、戸開き時安全障害検知部１２４が作動しているかどうかを確認する（ステップＳ３）。戸開き時安全障害検知部１２４が作動していない場合には、戸開きを完了し（ステップＳ８）、更に安全障害検知時の動作となっている場合には、通常速度である通常時の動作に切り替える（ステップＳ９）。一方、ステップＳ３において戸開き時安全障害検知部１２４が作動している場合には、安全障害検知カウント部１２２が安全障害検知カウント値に１を加え（ステップＳ４）、安全障害検知カウント値が閾値に一致するかどうかを確認する（ステップＳ５）。安全障害検知カウント値が閾値に一致していない場合には、ドア制御部１２０は、ドアパネル１１０の動作方向を反転し、通常時よりも低速での戸閉じ動作である安全障害検知時の戸閉じ動作が行なわれるよう、ドアモータ１３０を制御し（ステップＳ６）、ステップＳ２に戻る。ステップＳ５において安全障害検知カウント値が閾値に一致する場合には、安全障害検知時トルク無効モードであるか否かを確認する（ステップＳ７）。安全障害検知時トルク無効モードは、予め設定されるドア制御における一つのモードであり、安全障害検知時トルク無効モードを設定するか否かのいずれかに設定される。ここで安全障害検知時トルク無効モードでない場合には、戸開きを完了し（ステップＳ８）、安全障害検知時の動作となっている場合には、通常速度である通常時の動作に切り替える（ステップＳ９）。一方、安全障害検知時トルク無効モードである場合には、ドアの開閉力を無効の状態とする（ステップＳ２１）。 (2) Control of Door Panel by Door Control Unit FIG. 4 is a sequence diagram of an example of processing of the door control unit 120. This process is executed when a normal opening / closing operation on a stop floor and an opening / closing operation by an opening / closing instruction by a passenger are performed. As shown in FIG. 4, the door control unit 120 first confirms whether or not the door-closing safety fault detection unit 112 and the door-opening safety fault detection unit 124 are activated simultaneously (step S <b> 1). Here, when operating simultaneously, the door control unit 120 makes the door opening / closing force invalid (no torque), for example, by stopping power supply to the door motor 130 (step S21). By disabling the door opening / closing force, the door panel 110 can be manually opened and closed. On the other hand, if the doors are not operating at the same time, the process proceeds to step S2 to check whether the door opening operation is being performed. If the door opening operation is being performed, the door opening safety fault detection unit 124 is operated. (Step S3). When the door opening safety fault detection unit 124 is not activated, the door opening is completed (step S8), and when the safety fault is detected, the normal speed operation is performed. (Step S9). On the other hand, when the door opening safety fault detection unit 124 is operating in step S3, the safety fault detection count unit 122 adds 1 to the safety fault detection count value (step S4), and the safety fault detection count value is a threshold value. (Step S5). When the safety failure detection count value does not match the threshold value, the door control unit 120 reverses the operation direction of the door panel 110 and closes the door when the safety failure is detected, which is a door closing operation at a lower speed than normal. The door motor 130 is controlled so that the operation is performed (step S6), and the process returns to step S2. If the safety failure detection count value matches the threshold value in step S5, it is confirmed whether or not the safety failure detection torque invalid mode is set (step S7). The torque failure mode at the time of safety failure detection is one mode in door control set in advance, and is set to whether or not to set the torque invalid mode at the time of safety failure detection. Here, when it is not the torque failure mode at the time of safety failure detection, the door opening is completed (step S8), and when it is the operation at the time of safety failure detection, the operation is switched to the normal speed operation at the normal speed (step S9). On the other hand, in the case of the torque failure mode at the time of safety failure detection, the door opening / closing force is disabled (step S21).

ステップＳ２に戻り、戸開き動作中でないと判定された場合には、ステップＳ１３に移行し、戸閉じ時安全障害検知部１１２が作動しているかどうかを確認する。戸閉じ時安全障害検知部１１２が作動していない場合には、戸閉じを完了し（ステップＳ１８）、安全障害検知時の動作となっている場合には、通常速度である通常時の動作に切り替える（ステップＳ１９）。戸閉じ時安全障害検知部１１２が作動している場合には、安全障害検知カウント部１２２が安全障害検知カウント値に１を加え（ステップＳ１４）、安全障害検知カウント値が閾値に一致するかどうかを確認する（ステップＳ１５）。ここで、安全障害検知カウント値が閾値に一致していない場合には、ドア制御部１２０は、ドアパネル１１０の動作方向を反転し、通常時よりも低速での戸開き動作である安全障害検知時の戸開き動作を行うよう、ドアモータ１３０を制御し（ステップＳ１６）、ステップＳ２に戻る。ステップＳ１５において安全障害検知カウント値が閾値に一致する場合には、安全障害検知時トルク無効モードであるか否かを確認する（ステップＳ１７）。ここで安全障害検知時トルク無効モードでない場合には、戸閉じを完了し（ステップＳ１８）、安全障害検知時の動作となっている場合には、通常速度である通常時の動作に切り替える（ステップＳ１９）。一方、安全障害検知時トルク無効モードである場合には、ドアの開閉力を無効の状態とする（ステップＳ２１）。ステップＳ８、ステップＳ１８及びステップＳ２１のいずれかの処理を完了した後は、安全障害検知カウント値をリセットし（ステップＳ２２）、処理を終了する。   Returning to step S2, if it is determined that the door-opening operation is not being performed, the process proceeds to step S13 to check whether the door-closing safety fault detection unit 112 is operating. When the door closing safety fault detection unit 112 is not operating, the door closing is completed (step S18), and when the safety fault is detected, the normal speed operation is performed. Switching (step S19). When the door closing safety fault detection unit 112 is operating, the safety fault detection count unit 122 adds 1 to the safety fault detection count value (step S14), and whether or not the safety fault detection count value matches the threshold value. Is confirmed (step S15). Here, when the safety failure detection count value does not match the threshold value, the door control unit 120 reverses the operation direction of the door panel 110 and detects a safety failure that is a door opening operation at a lower speed than normal. The door motor 130 is controlled to perform the door opening operation (step S16), and the process returns to step S2. If the safety fault detection count value matches the threshold value in step S15, it is confirmed whether or not the safety fault detection torque invalid mode is set (step S17). Here, when it is not the torque failure mode at the time of safety failure detection, the door closing is completed (step S18), and when it is the operation at the time of safety failure detection, the operation is switched to the normal operation at the normal speed (step S18). S19). On the other hand, in the case of the torque failure mode at the time of safety failure detection, the door opening / closing force is disabled (step S21). After completing any one of steps S8, S18, and S21, the safety failure detection count value is reset (step S22), and the process is terminated.

ここで、閾値は、エレベータ装置１００が設置されている環境に合わせて適宜設定することができる。具体的な閾値としては、例えば２〜４の間で設定することができ、特に２を設定することとしてもよい。ドアの開閉力を無効とした場合には、ドアパネル１１０は手動により開閉可能となり、設定によっては、非常停止状態とし、外部に異常が報知されることとしてもよい。   Here, the threshold value can be appropriately set according to the environment where the elevator apparatus 100 is installed. As a specific threshold value, for example, it can be set between 2 and 4, and 2 may be set in particular. When the door opening / closing force is invalidated, the door panel 110 can be manually opened and closed, and depending on the setting, an emergency stop state may be established and an abnormality may be notified to the outside.

（３）本実施の形態の効果
以上説明したように、本実施の形態においては、ドア制御部１２０が、安全障害検知時の戸開き動作中に戸開き時安全障害検知部１２４が作動した際には、安全障害検知時の戸閉じ動作を行い、安全障害検知時の戸閉じ動作中に戸閉じ時安全障害検知部１１２が作動した際に、安全障害検知時の戸開き動作を行うため、戸閉じ時の安全装置が作動した後に、戸袋に引き込まれそうな物がある場合や、又は戸開き時の安全装置が作動した後に、ドアパネルに挟まれそうな物がある場合であっても、より安全なドアパネルの動作を行うことができる。 (3) Effects of the present embodiment As described above, in the present embodiment, when the door-opening safety fault detection unit 124 operates during the door-opening operation when the safety fault is detected. In order to perform the door closing operation at the time of safety failure detection, and when the door closing safety failure detection unit 112 is activated during the door closing operation at the time of safety failure detection, Even if there is something that is likely to be pulled into the door pocket after the safety device at the time of door closing is activated, or even if there is something that is likely to be pinched by the door panel after the safety device at the time of door opening is activated, Safer door panel operation can be performed.

また、戸開き時安全障害検知部１２４又は戸閉じ時安全障害検知部１１２が作動した回数を数える安全障害検知カウント部１２２を備え、カウント値が閾値の場合に、戸開き動作又は戸閉じ動作を完了することとした場合には、戸閉じ時にドアパネル１１０に挟まれる物、及び戸開き時に戸袋に引き込まれる物の両方が動かせなくなっている場合や安全障害検知部に不具合がある場合等においても、際限なく戸開き動作、及び戸閉じ動作が繰り返されることがなく、エレベータ装置１００を適宜通常状態に復帰させることができる。   In addition, a safety failure detection counting unit 122 that counts the number of times that the door-opening safety failure detection unit 124 or the door-closing safety failure detection unit 112 is operated is provided. When it is decided to complete, even when both the thing pinched by the door panel 110 when the door is closed and the thing pulled into the door bag when the door is opened cannot be moved or there is a problem in the safety fault detection unit, The door opening operation and the door closing operation are not repeated indefinitely, and the elevator apparatus 100 can be appropriately returned to the normal state.

また、戸開き時安全障害検知部１２４又は戸閉じ時安全障害検知部１１２が作動した回数を数える安全障害検知カウント部１２２を備え、カウント値が閾値の場合で安全障害検知時トルク無効モードの場合には、戸開き及び戸閉じのトルクを供給しない戸開閉力無効とすることができ、この場合には、戸閉じ時にドアパネル１１０に挟まれる物、及び戸開き時に戸袋に引き込まれる物の両方が動かせなくなっていても、ドアパネル１１０は手動で開閉可能となるため、より安全にドアの開閉を妨げている物を排除することができる。また、戸開き時安全障害検知部１２４又は戸閉じ時安全障害検知部１１２が、同時に動作した場合にも戸開閉力無効とすることができ、この場合においても、戸閉じ時にドアパネル１１０に挟まれる物、及び戸開き時に戸袋に引き込まれる物の両方が動かせなくなっていても、安全に物を排除することができる。   In addition, a safety failure detection counting unit 122 that counts the number of times the door-opening safety failure detection unit 124 or the door-closing safety failure detection unit 112 is operated is provided, and when the count value is a threshold value and the safety failure detection torque invalid mode is set The door opening and closing force that does not supply the door opening and closing torque can be disabled. In this case, both the object sandwiched by the door panel 110 when the door is closed and the object pulled into the door bag when the door is opened Even if the door cannot be moved, the door panel 110 can be manually opened and closed, so that it is possible to more safely remove an object that prevents the door from being opened and closed. Also, the door opening / closing force can be disabled even when the door opening safety fault detection unit 124 or the door closing safety fault detection unit 112 operate simultaneously, and even in this case, the door opening / closing force is sandwiched between the door panels 110. Even if both the object and the object drawn into the door pocket when the door is opened cannot be moved, the object can be safely removed.

また、安全障害検知時の戸開き動作は、通常の戸開き動作よりも低速の戸開き動作とし、また、安全障害検知時の戸閉じ動作は、通常の戸開き動作よりも低速の戸閉じ動作である場合には、より安全に安全障害検知の原因を排除することができる。   The door opening operation at the time of safety failure detection is a slower door opening operation than the normal door opening operation, and the door closing operation at the time of safety failure detection is a lower door opening operation than the normal door opening operation. If this is the case, the cause of the safety fault detection can be eliminated more safely.

（４）他の実施の形態
なお上述の実施の形態においては、安全障害検知カウント部１２２を有し、更に戸開き及び戸閉じのトルクを供給しない戸開閉力無効の機能を有することとしたが、これらの両方又はいずれかを有しないような構成であってもよい。例えば、図４のシーケンス図には、安全障害検知カウント部及び戸開閉力無効の機能の両方を有しない構成について示されている。このシーケンス図によれば、ドア制御部１２０は、まず、ステップＳ２において、戸開き動作中であるかどうかを確認し、戸開き動作中である場合には、戸開き時安全障害検知部１２４が作動しているかどうかを確認する（ステップＳ３）。戸開き時安全障害検知部１２４が作動していない場合には、戸開きを完了し（ステップＳ８）、安全障害検知時の動作となっている場合には、通常速度である通常時の動作に切り替え（ステップＳ９）、処理を終了する。戸開き時安全障害検知部１２４が作動している場合には、ドアパネルの動作方向を反転し、通常時よりも低速での戸閉じ動作である安全障害検知時の戸閉じ動作を行うよう、ドアモータ１３０を制御し（ステップＳ６）、ステップＳ２に戻る。 (4) Other Embodiments In the above-described embodiment, the safety failure detection count unit 122 is provided, and the door opening / closing force invalid function that does not supply door opening / closing torque is provided. The configuration may be such that neither or both of them are provided. For example, the sequence diagram of FIG. 4 shows a configuration that does not have both the safety failure detection count unit and the door opening / closing force invalid function. According to this sequence diagram, the door control unit 120 first checks in step S2 whether the door opening operation is being performed. If the door opening operation is being performed, the door opening safety fault detection unit 124 It is confirmed whether it is operating (step S3). When the door opening safety fault detection unit 124 is not operating, the door opening is completed (step S8), and when it is an operation at the time of safety fault detection, the normal speed which is a normal speed is set. Switching (step S9), the process ends. When the door-opening safety fault detection unit 124 is operating, the door motor is reversed so that the door motor operates in a door-closing operation when a safety fault is detected, which is a door-closing operation at a lower speed than normal. 130 is controlled (step S6), and the process returns to step S2.

ステップＳ２で、戸開き動作中でないと判定された場合には、ステップＳ１３に移行し、戸閉じ時安全障害検知部１１２が作動しているかどうかを確認する。戸閉じ時安全障害検知部１１２が作動していない場合には、戸閉じを完了し（ステップＳ１８）、安全障害検知時の動作となっている場合には、通常速度である通常時の動作に切り替え（ステップＳ９）、処理を終了する。戸閉じ時安全障害検知部１１２が作動している場合には、ドアパネルの動作方向を反転し、通常時よりも低速での戸開き動作である安全障害検知時の戸開き動作を行うよう、ドアモータ１３０を制御し（ステップＳ１６）、ステップＳ２に戻る。   If it is determined in step S2 that the door opening operation is not being performed, the process proceeds to step S13 to check whether the door closing safety fault detection unit 112 is operating. When the door closing safety fault detection unit 112 is not operating, the door closing is completed (step S18), and when the safety fault is detected, the normal speed operation is performed. Switching (step S9), the process ends. When the door closing safety fault detection unit 112 is in operation, the door motor is reversed so that the door panel is moved in the direction of operation, and the door opening operation is performed at the time of safety fault detection, which is a door opening operation at a lower speed than normal. 130 is controlled (step S16), and the process returns to step S2.

ドア制御部１２０の処理を、このような処理とした場合であっても、戸閉じ時の安全装置が作動した後に、戸袋に引き込まれそうな物がある場合や、又は戸開き時の安全装置が作動した後に、ドアパネルに挟まれそうな物がある場合であっても、より安全なドアパネルの動作を行うことができる。また、図５の制御シーケンスに、戸開き時安全障害検知部１２４及び戸閉じ時安全障害検知部１１２が同時に動作した場合の戸開閉力無効の機能、安全障害検知カウント部１２２のカウント値が閾値となった場合の戸開き又は戸閉じ動作の継続の機能、安全障害検知カウント部１２２のカウント値が閾値となった場合の戸開閉力無効の機能のいずれか１つ以上を設けることとしてもよい。   Even when the door control unit 120 performs such a process, there may be an object that is likely to be drawn into the door pocket after the safety device at the time of closing the door is operated, or the safety device at the time of opening the door. Even if there is an object that is likely to be caught between the door panels after the operation, the door panel can be operated more safely. Further, in the control sequence of FIG. 5, the door opening / closing force invalid function when the door opening safety fault detection unit 124 and the door closing safety fault detection unit 112 operate simultaneously, and the count value of the safety fault detection counting unit 122 is a threshold value. One or more of the function of continuation of the door opening or closing operation in the case of becoming, and the function of invalidating the door opening / closing force when the count value of the safety failure detection count unit 122 becomes a threshold value may be provided. .
