Abstract

PROBLEM TO BE SOLVED: To provide a device which detects whether an elevator door is closing normally or not.SOLUTION: A proximal sensor 2 is provided at an end of the door opening of a high speed door 1L of a cage, and a bending part 3 is formed at an end of the door closing of a low speed door 2L of the cage. When all doors 1L, 1R, 2L, 2R are in closed state, the proximal sensor 2 detects the state of the bending part 3 and determines that the relative positions of the high speed door 1L and the low speed door 2L are normal and confirms the door of each cage is closed normally.

Description

本発明は、出入口を開閉するかごドア及び乗場ドアを備えたエレベータドア装置において、ドアの動作異常を検出する装置に関するものである。   The present invention relates to an apparatus for detecting an abnormal operation of a door in an elevator door apparatus including a car door that opens and closes an entrance and a landing door.

通常、エレベータのドア装置は、ドア連動機構を介して、かごドアと乗場ドアが同期して出入口を開閉する構成になっている。このとき、特に戸閉時に、障害物があるとかごドア及び乗場ドアの一方又は両方が正常に閉じない場合がある。この状態、つまり出入口が閉じていない状態でかごが昇降すると危険であるため、この戸閉異常を検出する装置が従来から考えられている。   Normally, an elevator door device is configured such that a car door and a landing door are synchronized with each other via a door interlocking mechanism to open and close an entrance. At this time, particularly when the door is closed, if there is an obstacle, one or both of the car door and the landing door may not be closed normally. In this state, that is, when the car goes up and down in a state where the doorway is not closed, there is a conventional device for detecting this door closing abnormality.

従来の戸閉異常を検出する装置の例を図９により説明する。図９は２枚戸片開きのエレベータドア装置の出入口付近の横断面図である。図において、８１はかご側の高速ドア、８２はかご側の低速ドアであり高速ドア８１の半分の速度で開閉する。９１は乗場側の高速ドア、９２は乗場側の低速ドアであり高速ドア９１の半分の速度で開閉する。かご高速ドア８１と乗場高速ドア９１とは連動機構（図示省略）によって連動して開閉する構成になっている。従って、かご高速ドア８１と乗場高速ドア９１、かご低速ドア８２と乗場低速ドア９２は、それぞれ同一速度で同期して開閉する。   An example of a conventional device for detecting an abnormal door closing will be described with reference to FIG. FIG. 9 is a cross-sectional view of the vicinity of an entrance / exit of an elevator door device with two doors. In the figure, 81 is a car-side high-speed door, and 82 is a car-side low-speed door that opens and closes at half the speed of the high-speed door 81. 91 is a high-speed door on the landing side, and 92 is a low-speed door on the landing side, which opens and closes at half the speed of the high-speed door 91. The car high speed door 81 and the landing high speed door 91 are configured to open and close in conjunction with each other by an interlocking mechanism (not shown). Accordingly, the car high-speed door 81 and the landing high-speed door 91, and the car low-speed door 82 and the landing low-speed door 92 open and close at the same speed.

８３はかご高速ドア８１に設置された投受光素子を備えた光センサ、９３は乗場高速ドア９１に設置された反射板であり、光センサ８３からの光ビームを反射して、光センサ８３をオンにする。これらの光センサ８３と反射板９３により、両高速ドア８１，９１が同期しているか否かを検出する。
８４はかご低速ドア８２に設置された投受光素子を備えた光センサ、９４は乗場低速ドア９２に設置された反射板であり、光センサ８４からの光ビームを反射して、光センサ８４をオンにする。これらの光センサ８４と反射板９４により、両低速ドア８２，９２が同期しているか否かを検出する。 83 is an optical sensor having a light projecting / receiving element installed in the car high speed door 81, and 93 is a reflector installed in the landing high speed door 91. The light sensor 83 reflects the light beam to turn on. The optical sensor 83 and the reflector 93 detect whether or not the high speed doors 81 and 91 are synchronized.
84 is an optical sensor having a light projecting / receiving element installed in the car low speed door 82, and 94 is a reflecting plate installed in the landing low speed door 92, which reflects the light beam from the optical sensor 84, turn on. These optical sensor 84 and reflector 94 detect whether or not both low speed doors 82 and 92 are synchronized.

前記構成により、障害物によって両高速ドア８１と９１が同期しない場合（即ち相対変位がある場合）には、光センサ８３がオフになり両者の不同期を検出する。また両低速ドア８２と９２が同期しない場合には、光センサ８４がオフになり両者の不同期を検出する。   With the above configuration, when the high-speed doors 81 and 91 are not synchronized with each other due to an obstacle (that is, when there is a relative displacement), the optical sensor 83 is turned off and the synchronization between the two is detected. When the low-speed doors 82 and 92 are not synchronized, the optical sensor 84 is turned off to detect the unsynchronization between the two.

特開２００２−３１６７８２号公報JP 2002-316682 A

前記の構成の場合、両ドア８１と９１、または８２と９２が同期したまま変位すれば、光センサ８３，８４ではこの変位を検出できないという問題がある。例えば、紐状の異物がかご高速ドア８１と乗場高速ドア９１の先端に跨って引っ掛かっている場合、両ドア８１，９１は同時に同量だけ変位するため、両ドア８１，９１は同期したままである。そのため、光センサ８３はオン状態を維持するため、異物検出ができないことになる。   In the case of the configuration described above, there is a problem that if the doors 81 and 91 or 82 and 92 are displaced while being synchronized, the optical sensors 83 and 84 cannot detect this displacement. For example, when a string-like foreign object is caught across the tip of the car high speed door 81 and the landing high speed door 91, the doors 81 and 91 are displaced by the same amount at the same time. is there. Therefore, since the optical sensor 83 is kept on, foreign matter cannot be detected.

At least one of the car door or the landing door has a detection device that detects a relative displacement between the high-speed door and the low-speed door when the car door and the landing door are in a door-closed state. And the door closed end of the low-speed door.

また本発明は、出入口を開閉するかごドアと、前記かごドアと同期して移動する乗場ドアとを備えたエレベータドア装置において、かごドアと乗場ドアとが戸閉状態にあるときにかごドアの戸開端部と乗場ドアの戸開端部の少なくとも一方が所定以上戸開側にあることを検出する検出装置を設けたものである。

本発明の実施の形態を図１〜図３により説明する。図１は４枚戸中央開きのかごドアの横断面図で下方がかご内側である。図２，図３は図１の戸閉異常を説明する図である。
図において、１Ｌ及び１Ｒは左右の高速ドア、２Ｌ及び２Ｒは左右の低速ドアでありそれぞれ高速ドア１Ｌ，１Ｒの半分の速度で開閉する。２は高速ドア１Ｌの戸開端下部に設けた近接センサ、３は低速ドア２Ｌの戸閉端に形成された屈曲部である。一般にドアの上方にはドア開閉方向に伸びたレールが設けられ、ドアはその上部に設けたローラによって前記レールに沿って開閉移動するため、障害物が挟まった場合、ドアの下方が変位することになる。そこで、近接センサ２は高速ドア１Ｌの下方に設置してある。 An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a cross-sectional view of a four-door centrally opened car door, and the lower side is the car inside. 2 and 3 are diagrams for explaining the door closing abnormality of FIG.
In the figure, 1L and 1R are left and right high-speed doors, and 2L and 2R are left and right low-speed doors, which open and close at half the speed of the high-speed doors 1L and 1R, respectively. 2 is a proximity sensor provided at the lower part of the door opening end of the high speed door 1L, and 3 is a bent portion formed at the door closing end of the low speed door 2L. Generally, a rail extending in the door opening / closing direction is provided above the door, and the door is opened / closed along the rail by a roller provided on the upper portion thereof, so that when an obstacle is caught, the lower portion of the door is displaced. become. Therefore, the proximity sensor 2 is installed below the high speed door 1L.

次にこの装置の動作を説明する。通常の戸閉状態では図１に示すように近接センサ２は屈曲部３と対向する位置にくるためオンになる。障害物が挟まった場合には、図２に示すように、戸閉状態では高速ドア１Ｌと１Ｒはその下部が戸開方向に変位することになる。そうすると、近接センサ２は屈曲部３と対向しなくなるためオフになり、戸閉異常を検出することになる。   Next, the operation of this apparatus will be described. In a normal door-closed state, the proximity sensor 2 is turned on because the proximity sensor 2 comes to a position facing the bent portion 3 as shown in FIG. When an obstacle is caught, as shown in FIG. 2, the lower parts of the high speed doors 1L and 1R are displaced in the door opening direction in the door closed state. Then, since the proximity sensor 2 does not face the bent portion 3, the proximity sensor 2 is turned off and a door closing abnormality is detected.

尚、図３に示すように、高速ドア１Ｌ，１Ｒは正常で、低速ドア２Ｌにのみ障害物が引っ掛かるケースは稀であるが、この場合でも、屈曲部３が近接センサ２から外れるくらい大幅に低速ドア２Ｌの下部が戸開方向に変位した場合には、近接センサ２でこの変位を検出することができる。   As shown in FIG. 3, the high-speed doors 1L and 1R are normal, and it is rare that an obstacle is caught only on the low-speed door 2L. However, even in this case, the bending portion 3 is greatly disengaged from the proximity sensor 2. When the lower part of the low speed door 2L is displaced in the door opening direction, the proximity sensor 2 can detect this displacement.

また、紐状の障害物が高速ドア１Ｌに引っ掛かり、高速ドア１Ｌのみが変位した場合でも、前記と同様にこの変位を検出することができるが、右方のドア１Ｒ，２Ｒ側には近接センサを設置していないため、右方のドア１Ｒ，２Ｒ側のみの変位も検出する必要がある場合には、左方と同様に右方にも近接センサを設置すればよい。   Further, even when a string-like obstacle is caught on the high speed door 1L and only the high speed door 1L is displaced, this displacement can be detected in the same manner as described above, but the right doors 1R and 2R are provided with proximity sensors. Since it is not installed, if it is necessary to detect displacement only on the right door 1R, 2R side, a proximity sensor may be installed on the right as well as on the left.

図４は本発明の他の実施の形態を示す図で、図１に相当する図である。図１との相違点は、近接センサ２に相当する位置の低速ドア２Ｌの屈曲部３を切り欠き、戸閉状態において近接センサ２と対向する位置に検出部４を設けたことである。   FIG. 4 is a view showing another embodiment of the present invention and corresponds to FIG. The difference from FIG. 1 is that the bent portion 3 of the low speed door 2L at a position corresponding to the proximity sensor 2 is cut out, and the detection unit 4 is provided at a position facing the proximity sensor 2 in the door closed state.

この実施の形態では、高速ドア１Ｌの変位の検出は図１の場合と同じであるが、検出部４の近接センサ２との対向幅が図１の屈曲部３の対向幅よりも狭くなっているため、低速ドア２Ｌの変位が比較的小さくても検出することができる。   In this embodiment, the detection of the displacement of the high-speed door 1L is the same as in FIG. 1, but the width of the detector 4 facing the proximity sensor 2 is narrower than the width of the bent portion 3 of FIG. Therefore, even if the displacement of the low speed door 2L is relatively small, it can be detected.

図５は本発明の更に他の実施の形態を示す図で、図１に相当する図である。図１との相違点は、近接センサ２の代わりにレーザセンサ５を設けたこと、及び屈曲部３に反射板６を設けたこと、及びこの反射板６を清掃するブラシ７を高速ドア２の戸開端下部に設けたことである。   FIG. 5 is a view showing still another embodiment of the present invention and corresponds to FIG. The difference from FIG. 1 is that a laser sensor 5 is provided instead of the proximity sensor 2, a reflecting plate 6 is provided at the bent portion 3, and a brush 7 for cleaning the reflecting plate 6 is attached to the high-speed door 2. This is provided at the lower part of the door open end.

この実施の形態では、高速ドア１Ｌの変位の検出は図１，図４の場合と同じであるが、反射板６のレーザセンサ５との対向幅が図４の検出部４の幅と同程度まで狭くなっているため、低速ドア２Ｌの変位が比較的小さくても検出することができる。また、図４に比べ低速ドア２Ｌの加工が少なくて済む。更にブラシ７を設けることにより反射板６の清掃が行えるため、誤動作を減少させることができる。   In this embodiment, the detection of the displacement of the high-speed door 1L is the same as in the case of FIGS. 1 and 4, but the width of the reflector 6 facing the laser sensor 5 is about the same as the width of the detector 4 in FIG. Therefore, even if the displacement of the low speed door 2L is relatively small, it can be detected. Further, the processing of the low speed door 2L is less than that in FIG. Furthermore, since the reflecting plate 6 can be cleaned by providing the brush 7, malfunctions can be reduced.

以上の各実施の形態では、４枚戸中央開きのかごドアを対象にしているが、高速ドア，中速ドア，低速ドアを有する６枚戸中央開きのかごドアでも同様である。この場合、前記の実施の形態は高速ドアと中速ドアとの関係になる。また、中速ドアと低速ドアとの間に近接センサ２等を設置するか否かは、設置現場の事情に合わせて決めればよい。右方のドアについても同じである。
また、前記のドアを中央で半分に分割して考えると、２枚戸片開きと同様の形状となるため、片開きのドアにも同様に適用することができる。
更に、近接センサ２やレーザセンサ５等は右方のドアにも設置可能であるし、また本実施の形態を乗場ドアに適用することもできる。 In each of the above-described embodiments, a four-door centrally opened car door is targeted, but the same applies to a six-door centrally opened car door having a high-speed door, a medium-speed door, and a low-speed door. In this case, the embodiment described above has a relationship between the high speed door and the medium speed door. Whether or not to install the proximity sensor 2 or the like between the medium speed door and the low speed door may be determined according to the circumstances of the installation site. The same is true for the right door.
In addition, when the door is divided in half at the center, the shape is the same as that of a two-door single door, so that the present invention can be similarly applied to a single door.
Further, the proximity sensor 2 and the laser sensor 5 can be installed on the right door, and this embodiment can be applied to the landing door.

図６は本発明の他の実施の形態を示す図で、図９に相当する図である。この実施の形態は２枚戸中央開きである。
図において、１１Ｌ及び１１Ｒは左右のかごドア、１２Ｌ及び１２Ｒは出入口柱、１３Ｌ及び１３Ｒは袖壁であり、一方の袖壁１３Ｌはかご内から開閉可能になっており、出入口柱１２Ｌの下方裏面に取り付けたレーザセンサ５の据付・保守点検が可能な構造になっている。１４はかごドア１１Ｌの戸開端下部に取り付けた検出体である。 FIG. 6 is a diagram showing another embodiment of the present invention and corresponds to FIG. This embodiment is a two-door central opening.
In the figure, 11L and 11R are left and right car doors, 12L and 12R are entrance / exit pillars, 13L and 13R are sleeve walls, and one sleeve wall 13L can be opened and closed from the inside of the car. The structure is such that the laser sensor 5 attached to can be installed and maintained. Reference numeral 14 denotes a detector attached to the lower part of the car door 11L.

２１Ｌ及び２１Ｒは左右の乗場ドア、２２Ｌ及び２２Ｒは三方枠の竪柱であり、一方の竪柱２２Ｌの裏面下方には反射板６が取り付けられている。２４は乗場ドア２１Ｌの戸開端下部に取り付けた検出体、７は乗場ドア２１Ｌの戸開端下部に取り付けたブラシである。   21L and 21R are left and right landing doors, 22L and 22R are three-sided frame pillars, and a reflector 6 is attached to the lower side of one of the pillars 22L. Reference numeral 24 denotes a detection body attached to the lower part of the door opening end of the landing door 21L, and 7 denotes a brush attached to the lower part of the door opening end of the landing door 21L.

この実施の形態は、通常の戸閉状態では図６に示すように、レーザセンサ５からのレーザビームが反射板６に反射されて戻ってくることにより、各ドア１１Ｌ，２１Ｌが正常に戸閉していることを検出する。
このとき、障害物等によってかごドア１１Ｌ又は乗場ドア２１Ｌの一方又は両方の下部が戸開方向に変位していると、レーザビームが遮断されて、戸閉異常を検出することができる。 In this embodiment, as shown in FIG. 6, in a normal door-closed state, the laser beam from the laser sensor 5 is reflected by the reflecting plate 6 and returned, so that the doors 11L and 21L are normally closed. Detect that you are doing.
At this time, if one or both lower parts of the car door 11L or the landing door 21L are displaced in the door opening direction by an obstacle or the like, the laser beam is interrupted, and the door closing abnormality can be detected.

また、レーザセンサ５等は右方のドアにも設置可能であるし、更に前記のドアを中央で半分に分割して考えると、１枚戸片開きと同様の形状となるため、片開きのドアにも同様に適用することができる。   Further, the laser sensor 5 and the like can be installed on the right door, and when the door is further divided into halves at the center, it has the same shape as a single door single door. The same applies to the door.

図７は本発明の他の実施の形態を示す図で、図６に相当する図であり、図６と同一符号は同一のものを示している。この実施の形態は４枚戸中央開きである。
図において、３１Ｌ，３１Ｒは、乗場の左右の高速ドア、３２Ｌ，３２Ｒは同じく左右の低速ドアでありそれぞれ高速ドア３１Ｌ，３１Ｒの半分の速度で開閉する。この実施の形態では、レーザセンサ５はかご低速ドア２Ｌの戸閉端下方裏面に取り付けられており、また反射板６は乗場低速ドア３２Ｌの戸閉端下方裏面に取り付けられている。 FIG. 7 is a diagram showing another embodiment of the present invention, which corresponds to FIG. 6, and the same reference numerals as those in FIG. 6 denote the same components. This embodiment is a four-door central opening.
In the figure, 31L and 31R are left and right high-speed doors on the landing, and 32L and 32R are left and right low-speed doors that open and close at half the speed of the high-speed doors 31L and 31R, respectively. In this embodiment, the laser sensor 5 is attached to the lower back surface of the car low speed door 2L, and the reflector 6 is attached to the lower back surface of the landing low speed door 32L.

この実施の形態においても、かご高速ドア１Ｌ又は乗場高速ドア３１Ｌの一方又は両方の下部が戸開方向に変位していると、レーザビームが遮断されて、戸閉異常を検出することができる。
また、かご低速ドア２Ｌ又は乗場低速ドア３２Ｌの一方又は両方の下部が戸開方向に変位していると、レーザビームが反射板に当たらなくなるので、戸閉異常を検出することができる。尚、かご低速ドア２Ｌと乗場低速ドア３２Ｌが戸開方向に同量だけ変位している場合には変位検出はできないが、両低速ドア２Ｌ，３２Ｌの間には、高速ドア１Ｌ，３１Ｌがあるため、かご低速ドア２Ｌと乗場低速ドア３２Ｌが戸開方向に同量だけ変位することは通常考えられないため、本構成で実用上は問題はない。 Also in this embodiment, if one or both lower portions of the car high speed door 1L or the landing high speed door 31L are displaced in the door opening direction, the laser beam is interrupted and a door closing abnormality can be detected.
Further, if one or both lower portions of the car low speed door 2L or the landing low speed door 32L are displaced in the door opening direction, the laser beam does not hit the reflecting plate, so that the door closing abnormality can be detected. When the car low speed door 2L and the landing low speed door 32L are displaced by the same amount in the door opening direction, the displacement cannot be detected, but between the low speed doors 2L and 32L, there are high speed doors 1L and 31L. For this reason, it is not usually considered that the car low speed door 2L and the landing low speed door 32L are displaced by the same amount in the door opening direction, so there is no practical problem with this configuration.

前記実施の形態では、４枚戸中央開きとしているが、６枚戸中央開きのドアでも同様である。この場合、前記の実施の形態は高速ドアと中速ドアとの関係になる。中速ドアと低速ドアとの間にレーザセンサ５等を設置するか否かは、設置現場の事情に合わせて決めればよい。
また、前記のドアを中央で半分に分割して考えると、２枚戸片開きと同様の形状となるため、片開きのドアにも同様に適用することができる。更に、レーザセンサ５等は右方のドアにも設置可能である。 Although the four-door central opening is used in the embodiment, the same applies to a six-door central opening door. In this case, the embodiment described above has a relationship between the high speed door and the medium speed door. Whether to install the laser sensor 5 or the like between the medium-speed door and the low-speed door may be determined according to the circumstances of the installation site.
In addition, when the door is divided in half at the center, the shape is the same as that of a two-door single door, so that the present invention can be similarly applied to a single door. Further, the laser sensor 5 and the like can be installed on the right door.

また、前記図５〜図７の実施の形態においてはレーザセンサ５は低い位置にあるためセンサの光軸調整が行いにくい場合も考えられる。このときには図８に示すように、鏡５ａを使用して、レーザセンサ５の設置位置を高くすることもできる。更に、レーザセンサ５や反射板６の耐粉塵用の保護としてカバーを設けてもよい。
更にまた、前記の図４〜図７の実施の形態において、近接センサ２と検出部４や、レーザセンサ５と反射板６を逆の位置に配置することもできる。 In the embodiments shown in FIGS. 5 to 7, the laser sensor 5 is located at a low position, so that it may be difficult to adjust the optical axis of the sensor. At this time, as shown in FIG. 8, the installation position of the laser sensor 5 can be raised by using a mirror 5a. Further, a cover may be provided as protection for dust resistance of the laser sensor 5 and the reflection plate 6.
Furthermore, in the embodiment shown in FIGS. 4 to 7, the proximity sensor 2 and the detection unit 4, or the laser sensor 5 and the reflection plate 6 can be arranged at opposite positions.

以上の各実施の形態においては、近接センサ２やレーザセンサ５は戸閉状態で作動するようにしている。この場合、戸閉状態になったら近接センサ２やレーザセンサ５を動作させてもよいし、近接センサ２やレーザセンサ５は常時動作させておき、戸閉状態になったら、近接センサ２やレーザセンサ５の信号を図示省略した制御装置に入力するようにしてもよい。
以上の各実施の形態において、近接センサ２やレーザセンサ５の代わりに投光部と受光部が分離されたタイプの光電装置を使用することもできる。 In each of the embodiments described above, the proximity sensor 2 and the laser sensor 5 are operated in a door-closed state.
