[0002] 従来のエレベータのドア安全装置では、セーフティシューの下端部から異物検出 部材が突出している。紐状の異物がドア間に挟まれると、異物検出部材が異物により 押圧されて変位する。これにより、異物が検出され、ドアが開かれる (例えば、特許文 献 1参照)。 [0002] In a conventional elevator door safety device, a foreign object detection member protrudes from the lower end of the safety shoe. When a string-shaped foreign object is caught between the doors, the foreign object detection member is pressed and displaced by the foreign object. As a result, the foreign object is detected and the door is opened (see, for example, Patent Document 1).

発明を実施するための最良の形態 BEST MODE FOR CARRYING OUT THE INVENTION
[0008] 以下、この発明の好適な実施の形態について図面を参照して説明する。 [0008] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
実施の形態 1. Embodiment 1.
図 1はこの発明の実施の形態 1によるエレベータのドア安全装置を示す構成図であ る。図において、力ご出入口 1は、第 1及び第 2のかごドア 2, 3により開閉される。第 1 のかごドア 2の戸閉端部には、上下方向に互いに等間隔をおいて複数の検出光（図 中矢印で示す)を投光する投光器 4が取り付けられている。投光器 4は、第 1のかごド ァ 2の上下方向全長に渡って配置されている。 FIG. 1 is a configuration diagram showing an elevator door safety device according to Embodiment 1 of the present invention. In the figure, a power car doorway 1 is opened and closed by first and second car doors 2, 3. A floodlight 4 is attached to the closed end of the first car door 2 and emits a plurality of detection lights (indicated by arrows in the figure) at equal intervals in the vertical direction. The floodlight 4 is arranged over the entire length of the first car door 2 in the vertical direction.
[0009] 第 2のかごドア 3の戸閉端部には、投光器 4からの検出光を受光する受光器 5が投 光器 4に対向して取り付けられている。受光器 5は、第 2のかごドア 3の上下方向全長 に渡って配置されている。光電センサ装置 6は、投光器 4及び受光器 5を有し、検出 光が遮断されることにより、かごドア 2, 3により挟まれる異物を検出する。 [0009] A light receiver 5 that receives the detection light from the light emitter 4 is attached to the closed end of the second car door 3 so as to face the light emitter 4. The light receiver 5 is arranged over the entire length of the second car door 3 in the vertical direction. The photoelectric sensor device 6 includes a light emitter 4 and a light receiver 5, and detects a foreign object caught between the car doors 2 and 3 by blocking the detection light.
[0010] かごドア 2, 3の開閉は、ドア制御装置 7により制御される。ドア制御装置 7は、投光 器 4を制御するとともに、受光器 5からの検出信号に基づいて、かごドア 2, 3間の異 物の有無を判断する。また、ドア制御装置 7は、コンピュータを有し、例えばかご上に 搭載されている。 [0010] Opening and closing of the car doors 2 and 3 is controlled by a door control device 7. The door control device 7 controls the light projector 4 and determines whether there is a foreign object between the car doors 2 and 3 based on the detection signal from the light receiver 5. Further, the door control device 7 includes a computer, and is mounted on the car, for example.
[0011] 力ごの運転は、運行制御装置 8により制御される。運行制御装置 8は、コンピュータ を有し、例えば昇降路内に設置されている。また、ドア制御装置 7と運行制御装置 8と は、互いに通信可能に接続されている。エレベータ制御装置 9は、ドア制御装置 7及 び運行制御装置 8を有して 、る。 [0011] Operation of the force hammer is controlled by an operation control device 8. The operation control device 8 includes a computer and is installed, for example, in a hoistway. In addition, door control device 7 and operation control device 8 are communicably connected to each other. The elevator control device 9 includes a door control device 7 and an operation control device 8.
[0012] ドア制御装置 7は、戸閉動作中、全戸閉時及び力ごの走行時に、光電センサ装置 6 による異物検出機能が有効であるように設定されている。従って、光電センサ装置 6 による異物検出機能は、力ごの走行開始直後にも有効となっている。 [0012] The door control device 7 is set so that the foreign object detection function by the photoelectric sensor device 6 is effective during the door closing operation, when the door is fully closed, and when the power hammer is running. Therefore, the foreign object detection function by the photoelectric sensor device 6 is effective even immediately after the power hammer starts running.
[0013] 戸閉動作中に光電センサ装置 6により異物が検出されると、ドア制御装置 7は、ドア モータ（図示せず）に反転戸開指令を出力する。力ごの走行開始直後に光電センサ 装置 6により異物が検出されると、運行制御装置 8は、力ごを停止させ、直前に出発し た停止階の階床位置へ力ごを戻して戸開させる。 [0013] When a foreign object is detected by the photoelectric sensor device 6 during a door closing operation, the door control device 7 outputs a reverse door opening command to a door motor (not shown). When a foreign object is detected by the photoelectric sensor device 6 immediately after the force gun starts running, the operation control device 8 stops the force gun, returns the force gun to the floor position of the stopping floor from which it departed immediately, and opens the door. let
[0014] 図 2は図 1のかごドア 2, 3間に紐状の異物 10が挟まった状態を示す構成図である。 [0014] FIG. 2 is a configuration diagram showing a state in which a string-like foreign object 10 is caught between the car doors 2 and 3 of FIG. 1.
投光器 4には、上下方向に互 ヽに等間隔 (例えば 40〜50mm間隔）をお 、て設けら れた力ごドアセンサ素子である複数の力ご発光素子 11が設けられている。受光器 5 には、対応する力ご発光素子 11に対向する力ごドアセンサ素子である複数の力ご受 光素子（図示せず)が設けられて 、る。 The floodlight 4 is provided with a plurality of force light emitting elements 11, which are force door sensor elements, which are arranged at equal intervals (for example, 40 to 50 mm intervals) in the vertical direction. The light receiver 5 is provided with a plurality of force light receiving elements (not shown), which are force door sensor elements, facing the corresponding force light emitting elements 11.
[0015] 乗場出入口は、第 1の乗場ドア 12及び第 2の乗場ドア（図示せず）により開閉される[0015] The landing entrance is opened and closed by a first landing door 12 and a second landing door (not shown).
。かごには、かご敷居 13が設けられている。乗場には、乗場敷居 14が設けられてい る。 . The car is provided with a car threshold 13. The landing has a landing threshold of 14.
[0016] 全戸閉時に、かご発光素子 11及びかご受光素子が設けられていない部分でかごド ァ 2, 3間に異物 10が挟まれた場合、力ごが走行を開始することにより、例えば図 3に 示すように、異物 10に対する投光器 4及び受光器 5の位置がずれ、異物 10により検 出光が遮断される。これにより、異物 10がかごドア 2, 3間に挟まったことが検出され、 かごが停止される。この後、力ごは階床位置に戻され、戸開される。従って、異物 10 を取り除くことができる。 [0016] When all the doors are closed, if a foreign object 10 is caught between the car doors 2 and 3 in a part where the car light emitting element 11 and the car light receiving element are not provided, the force hammer starts running, causing the 3, the positions of the emitter 4 and the light receiver 5 are shifted relative to the foreign object 10, and the foreign object 10 blocks the detection light. As a result, it is detected that the foreign object 10 is caught between the car doors 2 and 3, and the car is stopped. After this, the lever is returned to its position on the floor and the door is opened. Therefore, foreign matter 10 can be removed.
[0017] 図 4は図 1のかごドア 2, 3間に紐状の異物 10が挟まった場合のドア動作、異物検 出機能及び力ご動作を示すタイミングチャートである。時刻 T1で全戸閉状態になつ た後も異物検出機能は有効となっている。この状態で力ごが走行を開始し、時刻 T2 で異物 10が検出されると、かごが停止される。この後、時刻 T3から時刻 T4の間にか ごが階床位置に戻される。そして、時刻 T4で階床位置にカゝごが停止され、戸開され る。 [0017] FIG. 4 is a timing chart showing the door operation, foreign object detection function, and force operation when a string-like foreign object 10 is caught between the car doors 2 and 3 of FIG. 1. The foreign object detection function remains valid even after the door is fully closed at time T1. The car starts running in this state, and when the foreign object 10 is detected at time T2, the car is stopped. Thereafter, the car is returned to the floor position between time T3 and time T4. Then, at time T4, the car is stopped at the floor position and the door is opened. Ru.
[0018] このようなエレベータのドア安全装置では、力ごの走行開始直後にも光電センサ装 置による異物検出機能が有効であるため、紐状の異物 10が光電センサ装置 6の検 出領域外で力ごドア 2, 3間に挟まれた場合でも、力ごが移動することで異物 10が光 電センサ装置 6の検出領域内に変位した際に異物 10を検出することができる。従つ て、紐状の異物 10をより確実に検出することができる。また、光電センサ装置 6を用い ているため、かごドア 2, 3の戸閉端部から異物検出部材が突出することはなぐ異物 検出部材の破損による戸閉動作の阻害が防止される。 [0018] In such an elevator door safety device, since the foreign object detection function by the photoelectric sensor device is effective even immediately after the force hammer starts running, the string-like foreign object 10 is detected outside the detection area of the photoelectric sensor device 6. Even if the foreign object 10 is caught between the force doors 2 and 3, the foreign object 10 can be detected when the force door moves and the foreign object 10 is displaced into the detection area of the photoelectric sensor device 6. Therefore, the string-like foreign object 10 can be detected more reliably. Further, since the photoelectric sensor device 6 is used, the foreign object detection member does not protrude from the closed end of the car doors 2, 3, thereby preventing the door closing operation from being hindered due to damage to the foreign object detection member.
[0019] 実施の形態 2. [0019] Embodiment 2.
次に、図 5はこの発明の実施の形態 2によるドア安全装置を示す構成図、図 6は図 5 の力ごが上方へ走行を開始した直後の状態を示す構成図である。第 1の乗場ドア 12 の戸閉端部の下端部には、乗場ドアセンサ素子としての乗場発光素子 15が設けら れている。第 2の乗場ドアの戸閉端部の下端部には、乗場発光素子 15に対向する乗 場ドアセンサ素子としての乗場受光素子（図示せず)が設けられている。実施の形態 2の光電センサ装置は、実施の形態 1と同様の投光器 4及び受光器 5 (図 1)に加えて 、乗場発光素子 15及び乗場受光素子を有している。 Next, FIG. 5 is a block diagram showing a door safety device according to a second embodiment of the present invention, and FIG. 6 is a block diagram showing a state immediately after the power tool in FIG. 5 starts traveling upward. A landing light emitting element 15 as a landing door sensor element is provided at the lower end of the closed end of the first landing door 12 . A hall light receiving element (not shown) as a hall door sensor element facing the hall light emitting element 15 is provided at the lower end of the closed end of the second hall door. The photoelectric sensor device of Embodiment 2 includes a hall light emitting element 15 and a hall light receiving element in addition to the same light projector 4 and light receiver 5 (FIG. 1) as in Embodiment 1.
[0020] 図 5に示すように、最下部に位置する力ご発光素子 11及び力ご受光素子とかご敷 居 13との間の間隔が比較的広い場合、この間隔内で異物 10がかごドア 2, 3間に挟 まれると、かごが停止している状態では異物 10を検出することができない。これに対 して、力ごが下方へ走行を開始した場合、最下部に位置する力ご発光素子 11からの 検出光が異物 10により遮断され、異物 10が検出される。 [0020] As shown in FIG. 5, when the distance between the force emitting element 11 and the force receiving element located at the lowest position and the car sill 13 is relatively wide, a foreign object 10 within this gap is detected as a car door. If the foreign object 10 is caught between 2 and 3, the foreign object 10 cannot be detected while the car is stopped. On the other hand, when the force gun starts traveling downward, the detection light from the force light emitting element 11 located at the bottom is blocked by the foreign object 10, and the foreign object 10 is detected.
[0021] 一方、図 5の状態からかごが上方へ走行を開始した場合、図 6に示すように、異物 1 0も上方へ変位され、乗場発光素子 15からの検出光が異物 10により遮断され、異物 10が検出される。 [0021] On the other hand, when the car starts traveling upward from the state shown in FIG. , a foreign object 10 is detected.
[0022] 従って、最下部に位置するかご発光素子 11及び力ご受光素子とかご敷居 13との 間の間隔が比較的広い場合であっても、光電センサ装置を用いて紐状の異物 10を より確実に検出することができる。 [0022] Therefore, even if the distance between the car light-emitting element 11 and the car light-receiving element located at the lowest position and the car sill 13 is relatively wide, the string-like foreign object 10 can be detected using the photoelectric sensor device. It can be detected more reliably.
[0023] なお、上記の例では、力ご発光素子 11及び力ご受光素子を上下方向に等間隔で 配置したが、位置により間隔を変えて配置してもよい。例えば、かごドアの下部では 等間隔とし、上部では配置密度を下部よりも小さくしてもよい。 [0023] In the above example, the force-emitting element 11 and the force-receiving element are arranged at equal intervals in the vertical direction. However, they may be arranged at different intervals depending on the position. For example, the lower part of the car door may be equally spaced, and the upper part may have a smaller density than the lower part.
また、上記の例では中央開き式のドア装置を示したが、この発明は片開き式のドア 装置にも適用できる。 Further, although the above example shows a center-opening door device, the present invention can also be applied to a single-opening door device.
さらに、異物検出時のエレベータ制御装置の機能として、異常検出信号を発報する ようにしてもよい。異常検出信号は、例えばエレベータ管理室に送信される。これによ り、保守員等が現場に行って異物を除去し、異常がないかどうかを点検することもで きる。また、異常検出信号に応じて、かご内や乗場に対して、異物を取り除くよう要求 する旨のアナウンスを放送するようにしてもょ 、。 Furthermore, as a function of the elevator control device when a foreign object is detected, an abnormality detection signal may be issued. The abnormality detection signal is transmitted to, for example, an elevator control room. This allows maintenance personnel and others to go to the site, remove foreign objects, and inspect for abnormalities. Additionally, in response to the abnormality detection signal, an announcement may be made to request that foreign objects be removed from the car or the landing area.
さらにまた、光電センサ装置による異物検出機能は、少なくとも戸閉動作中及びか ごの走行開始直後に有効であればよぐ例えば走行開始力 所定時間後に無効とし たり、カゝごが階床位置カゝら所定距離走行したら無効としたりしてもよい。 Furthermore, the foreign object detection function using the photoelectric sensor device can be activated at least when the door is closed and immediately after the car starts running. Alternatively, it may be invalidated after traveling a predetermined distance.
