Description

本発明は、ドアの開閉動作を制御しエレベータの運転効率の向上を図るエレベータのドア制御装置に関する。 The present invention relates to an elevator door control device that controls the opening and closing operation of a door to improve the operation efficiency of the elevator.

一般のエレベータにあっては、乗かごが目的の階に到着するとドアが開いて利用者は乗降することになるが、その時に乗降する利用者が少なくても多くてもドアの開いている時間は同じである。また、いたずらや間違いでかご呼びが登録された場合、利用者がいないときでもドアは予め設定された時間だけ戸開している。したがって、他階にいる利用者が乗場呼びを登録しても、この呼びに対する応答が迅速に行なわれず、利用者は長い時間待たされることになる。 In general elevators, when the car arrives at the target floor, the door opens and the user gets on and off. At that time, at least the number of users getting on and off the door is open. Are the same. Further, when a car call is registered due to mischief or mistake, the door is opened for a preset time even when there is no user. Therefore, even if a user on another floor registers a hall call, the response to this call is not made quickly, and the user waits for a long time.

このため従来、非接触式障害物検出装置の障害物を検出しない状態が所定時間継続した場合は、設定戸開時間経過前でも、全開中のドアに戸閉動作を行なわせるとともに、ドアの戸閉動作中に非接触式障害物検出装置が障害物を検出した場合は、このドアを障害物検出位置から所定距離だけ反転させ、その反転させた位置にドアを所定時間だけ停止させた後に、再度の戸閉動作を行なわせ、更に、ドアの再度の戸閉動作中に非接触式障害物検出装置が再度障害物を検出した場合は、前回反転時の所定距離よりも所定量増大させた距離だけドアを再度反転させ、利用者の安全を確保しつつ、運転効率の向上を図るようにしたものが提案されている（例えば、特許文献１参照）。 For this reason, conventionally, when a state in which no obstacle is detected by the non-contact type obstacle detection device has continued for a predetermined time, the door that has been fully opened is allowed to perform the door closing operation even before the set door opening time has elapsed. When the non-contact type obstacle detection device detects an obstacle during the closing operation, the door is inverted by a predetermined distance from the obstacle detection position, and after stopping the door at the inverted position for a predetermined time, If the non-contact type obstacle detection device detects an obstacle again during the door closing operation again, it is increased by a predetermined amount from the predetermined distance at the previous reversal. There has been proposed a device in which the door is reversed again by a distance so as to improve the driving efficiency while ensuring the safety of the user (see, for example, Patent Document 1).

また、乗かごの内部の乗客の有無を検出する荷重検出器を設け、この荷重検出器の乗客なしの信号により、ドアの開閉速度を上昇させ、運転効率の向上を図るようにしたものもある（例えば、特許文献２参照）。
特許第３２６００６９号（段落番号００１８〜００２５、図３）特開平１０−１９４６４２号公報（段落番号００２３〜００２８、図１） There is also a load detector that detects the presence or absence of passengers in the passenger car, and the door opening / closing speed is increased by a signal indicating no passenger in the load detector to improve driving efficiency. (For example, refer to Patent Document 2).
Japanese Patent No. 3260069 (paragraph numbers 0018 to 0025, FIG. 3) JP-A-10-194642 (paragraph numbers 0023 to 0028, FIG. 1)

しかしながら、前述した前者のものは、設定戸開時間経過前にドアを戸閉させることで運転効率の向上を図るようにしたものであるが、ドアの閉じ速度については考慮されていない。他階で登録された乗場呼び後の待ち時間を低減させることはエレベータのサービス性向上につながることから、利用者の安全を確保しつつ可能な限りこの時間を短縮することが望ましく、さらなる改善の余地があった。 However, in the former case, the door is closed before the set door opening time elapses so that the operation efficiency is improved, but the door closing speed is not considered. Reducing the waiting time after the landing call registered on the other floor leads to an improvement in the serviceability of the elevator, so it is desirable to shorten this time as much as possible while ensuring the safety of the user. There was room.

また、前述した後者のものは、荷重検出器が乗かご内に乗客がいないことを検出したときにドアの開閉速度を上昇させ、運転効率の向上を図るようにしたものであるが、例えば乗客が乗かごから乗場側へ降りようとして出入口に位置し、乗場側に体重をかけた状態にあると荷重検出が行われない恐れがあるとともに、乗場側から乗かごに乗り込もうとする利用者を検出することは不可能であり、このような乗客或いは利用者（以下、乗場側におりエレベータを利用しようとする利用者も便宜上、すべて乗客と呼ぶ）いる状態でドアの開閉速度を上昇させることは安全上好ましくなかった。 In the latter case, when the load detector detects that there are no passengers in the car, the door opening / closing speed is increased to improve the driving efficiency. Is located at the entrance and exits from the car to the landing side, and if there is weight on the landing side, load detection may not be performed, and users who try to get into the car from the landing side are detected It is impossible to increase the door opening and closing speed in such a state where there are passengers or users (hereinafter, users who are on the landing side and use the elevator are also called passengers for convenience). It was not preferable for safety.

本発明は、前述した従来技術における実状からなされたもので、その目的は、必要時に乗客の安全を確保しつつ高効率なドア制御を行うことのできるエレベータのドア制御装置を提供することにある。 The present invention has been made from the above-described prior art, and an object thereof is to provide an elevator door control device capable of performing highly efficient door control while ensuring the safety of passengers when necessary. .
