It should be noted that the present invention is not limited to this embodiment, and includes various design changes.

実施の形態１．
図１は、この発明の実施の形態１に係るエレベーター制御装置を用いたエレベーター全体を概念的に示す構成図である。図１において、利用客を乗せるかご１は、昇降路２の上部に設けられた電動機３によって回転される綱車４に巻き掛けられたロープ５の一端部に吊下されている。ロープ５の他端部には釣合い重り６が固定されており、かご１が昇降路２を上昇するときは釣合い重り６が下降するように動作する。 Embodiment 1 FIG.
FIG. 1 is a configuration diagram conceptually showing an entire elevator using the elevator control device according to Embodiment 1 of the present invention. In FIG. 1, a car 1 on which a passenger is placed is suspended from one end of a rope 5 that is wound around a sheave 4 that is rotated by an electric motor 3 provided in an upper part of a hoistway 2. A counterweight 6 is fixed to the other end of the rope 5, and when the car 1 moves up the hoistway 2, the counterweight 6 operates so as to lower.

昇降路２の壁面部には、各停止階床７ａ〜７ｃにおけるかご１の戸開閉可能位置に対応する位置に、光を反射する反射面を有する反射部材８ａ〜８ｃが突設されている。反射部材８ａ〜８ｃは、図２に拡大図を示すように、垂直方向の断面形状が略台形状に形成されており、斜め上方向き反射面と斜め下方向き反射面、およびそれらの間に設けられた垂直反射面の３面からなる反射面を有している。また、前記斜め上方向き反射面と斜め下方向き反射面は、昇降路２の壁面部に対して略等しい傾斜角度を有している。   Reflecting members 8a to 8c having reflecting surfaces that reflect light project from the wall surface of the hoistway 2 at positions corresponding to the door opening / closing positions of the car 1 in the respective stop floors 7a to 7c. As shown in the enlarged view of FIG. 2, the reflecting members 8 a to 8 c have a substantially trapezoidal cross-sectional shape in the vertical direction, and are provided between the obliquely upward reflecting surface and the obliquely downward reflecting surface, and between them. The reflecting surface is composed of three vertical reflecting surfaces. Further, the obliquely upward reflecting surface and the obliquely downward reflecting surface have substantially the same inclination angle with respect to the wall surface portion of the hoistway 2.

また、この反射部材８ａ〜８ｃに対向するかご１の前面上方部には、反射部材８ａ〜８ｃに光を照射すると共に、戻ってきた反射光を受光する信号発生受信手段である光発生受光装置９が設けられている。光発生受光装置９は、反射部材８ａ〜８ｃの斜め上方向き反射面に光を照射し、戻ってきた反射光を受光する第１の送受光器９ａ、反射部材８ａ〜８ｃの斜め下方向き反射面に光を照射し、戻ってきた反射光を受光する第２の送受光器９ｂ、反射部材８ａ〜８ｃの垂直反射面に光を照射し、戻ってきた反射光を受光する第３の送受光器９ｃを備えている。第１乃至第３の送受光器９ａ〜９ｃからの照射光は、信号制御部１０の指令によって反射部材８ａ〜８ｃに照射され、反射部材８ａ〜８ｃからの反射光は、信号制御部１０で処理される。信号制御部１０は、後述するエレベーター制御盤の指令に基づいて送受光器９ａ〜９ｃの送受光信号を制御している。なお、図２の符号１１はかご扉、符号１２は乗場扉を示している。   Further, a light generating / receiving device which is a signal generating / receiving unit that irradiates light on the reflecting members 8a to 8c and receives the reflected light returning to the upper part of the front surface of the car 1 facing the reflecting members 8a to 8c. 9 is provided. The light generating / receiving device 9 irradiates light on the obliquely upward reflecting surfaces of the reflecting members 8a to 8c, and receives the reflected light that has returned, and reflects the obliquely downward reflections of the reflecting members 8a to 8c. A second transmitter / receiver 9b that irradiates the surface with light and receives the reflected light that has returned, and a third transmitter that irradiates the vertical reflecting surface of the reflecting members 8a to 8c with light and receives the reflected light that has returned. A light receiver 9c is provided. Irradiation light from the first to third light transmitters / receivers 9 a to 9 c is irradiated to the reflecting members 8 a to 8 c according to a command from the signal control unit 10, and reflected light from the reflecting members 8 a to 8 c is transmitted to the signal control unit 10. It is processed. The signal control unit 10 controls the light transmission / reception signals of the light transmitters / receivers 9a to 9c based on commands from an elevator control panel described later. In FIG. 2, reference numeral 11 denotes a car door, and reference numeral 12 denotes a landing door.

図１に戻り、信号制御部１０で処理された第１乃至第３の送受光器９ａ〜９ｃによる送受光信号は、制御ケーブル１３によりエレベーター制御盤１４に伝送される。エレベーター制御盤１４は、電動機３の回転速度を制御するもので、図示しない制御回路を内蔵し、かご１を停止階床７ａ〜７ｃに停止させるときには所定の減速パターンに沿って減速させ、着床させる最終段階で信号制御部１０からの戸開閉可能位置の出力を受け、かご１を戸開閉可能位置に停止させる。   Returning to FIG. 1, the light transmission / reception signals by the first to third light transmitters / receivers 9 a to 9 c processed by the signal controller 10 are transmitted to the elevator control panel 14 by the control cable 13. The elevator control panel 14 controls the rotational speed of the electric motor 3 and incorporates a control circuit (not shown). When the car 1 is stopped at the stop floors 7a to 7c, the elevator control panel 14 decelerates along a predetermined deceleration pattern, In the final stage, the output of the door opening / closing position from the signal control unit 10 is received, and the car 1 is stopped at the door opening / closing position.

実施の形態１に係るエレベーター制御装置は前記のように構成されており、次にその動作について説明する。
先ず、かご１の着床時の動作について図３により説明する。図３は、実施の形態１に係るエレベーター制御装置の着床時におけるかご走行速度と各検出信号とのタイミングチャートである。図３において、信号制御部１０の指令により送受光器９ａ〜９ｃから光を照射させる。かご１が検出ゾーン内にある場合、送受光器９ａからの光は、図３（ａ）に示すように、反射部材８ａの斜め上方向き反射面により反射され、その反射光を受光して反射距離Ｌ１を検出する。同様に、送受光器９ｂからの光は、反射部材８ａの斜め下方向き反射面により反射され、その反射光を受光して反射距離Ｌ２を検出する。また、送受光器９ｃからの光は、反射部材８ａの垂直反射面により反射され、その反射光を受光して反射距離Ｌ３を検出する。 The elevator control device according to the first embodiment is configured as described above, and the operation thereof will be described next.
First, the operation when the car 1 is landed will be described with reference to FIG. FIG. 3 is a timing chart of the car traveling speed and each detection signal at the time of landing of the elevator control device according to the first embodiment. In FIG. 3, light is emitted from the light transmitters / receivers 9 a to 9 c according to a command from the signal control unit 10. When the car 1 is in the detection zone, the light from the light transmitter / receiver 9a is reflected by the obliquely upward reflecting surface of the reflecting member 8a as shown in FIG. 3 (a), and the reflected light is received and reflected. The distance L1 is detected. Similarly, the light from the light transmitter / receiver 9b is reflected by the obliquely downward reflecting surface of the reflecting member 8a, and the reflected light is received to detect the reflection distance L2. The light from the light transmitter / receiver 9c is reflected by the vertical reflecting surface of the reflecting member 8a, and the reflected light is received to detect the reflection distance L3.

ここで、図３（ｂ）に示すように、Ｌ１とＬ２との検出距離の関係が、Ｌ１＝Ｌ２となるよう制御することにより、停止階床７ａとかご１の床とが段差なく、精度よく着床させることが出来る。なお、図３（ｂ）では、かご１の下降走行時のタイミングチャートを図示しているが、かご１の上昇走行時は、送受光器９ａの検出距離Ｌ１と送受光器９ｂの検出距離Ｌ２との増減関係は逆になる。 Here, as shown in FIG. 3B, by controlling the relationship of the detection distance between L1 and L2 to be L1 = L2, there is no difference in level between the stop floor 7a and the floor of the car 1. It can be well implanted. FIG. 3B shows a timing chart when the car 1 is traveling downward. When the car 1 is traveling upward, the detection distance L1 of the light transmitter / receiver 9a and the detection distance L2 of the light transmitter / receiver 9b are illustrated. The increase / decrease relationship is reversed.

また、かご１が着床し、かご扉１１および乗場扉１２が戸開動作した後、かご１への利用客や物の乗り降りが行われ、かご１の重量が変動すると、それに伴い、ロープ５の伸びなどの影響により、かご１の着床位置が変動する。   In addition, after the car 1 is landed and the car door 11 and the landing door 12 are opened, passengers and objects get on and off the car 1 and the weight of the car 1 fluctuates. The landing position of the car 1 fluctuates due to the influence of the elongation of the car.

つまり、Ｌ１とＬ２との検出距離の関係が、Ｌ１＞Ｌ２となった場合、図４（ａ）に示すように着床初期時よりかご１内の重量が減量となったことを検出し、Ｌ１＜Ｌ２となった場合、図４（ｂ）に示すように着床初期時よりかご１内の重量が増量となったことを検出することが出来る。   That is, when the relationship between the detection distances of L1 and L2 is L1> L2, it is detected that the weight in the car 1 has decreased from the initial landing time as shown in FIG. When L1 <L2, as shown in FIG. 4B, it can be detected that the weight in the car 1 has increased from the initial stage of landing.

ここで、かご１の重量と変動分との関係を、信号制御部１０にて事前に記憶させておくことにより、Ｌ１およびＬ２の変動分の積上げ値から、現在のかご１の重量を検出させることが出来る。従って、秤装置を特別に設ける必要がなくなり、機器の種類および処理回路の削減が出来る。   Here, the current weight of the car 1 is detected from the accumulated values of the fluctuations of L1 and L2 by storing the relationship between the weight of the car 1 and the fluctuation in advance in the signal control unit 10. I can do it. Therefore, it is not necessary to provide a special scale device, and the types of equipment and processing circuits can be reduced.

なお、実施の形態１では、反射部材８ａ〜８ｃとして、垂直方向の断面形状が略台形状に形成され、斜め上方向き反射面と斜め下方向き反射面、およびそれらの間に設けられた垂直反射面の３面からなる反射面を有し、また、光発生受光装置９として、反射部材８ａ〜８ｃの斜め上方向き反射面に光を照射し、戻ってきた反射光を受光する第１の送受光器９ａ、反射部材８ａ〜８ｃの斜め下方向き反射面に光を照射し、戻ってきた反射光を受光する第２の送受光器９ｂ、反射部材８ａ〜８ｃの垂直反射面に光を照射し、戻ってきた反射光を受光する第３の送受光器９ｃを備えたものについて図示説明した。   In the first embodiment, as the reflecting members 8a to 8c, the vertical sectional shape is formed in a substantially trapezoidal shape, the obliquely upward reflecting surface, the obliquely downward reflecting surface, and the vertical reflection provided therebetween. The light transmitting / receiving device 9 has a reflecting surface composed of three surfaces, and irradiates the obliquely upward reflecting surfaces of the reflecting members 8a to 8c with light and receives the reflected light that has returned. Light is applied to the obliquely downward reflecting surfaces of the light receiver 9a and the reflecting members 8a to 8c, and light is irradiated to the vertical reflecting surfaces of the second light transmitting and receiving device 9b and the reflecting members 8a to 8c that receive the reflected light that has returned. In the above description, the third transmitter / receiver 9c that receives the reflected light that has returned is illustrated.

しかし、かご１の着床位置の検出と、かご１の重量の変動を検出するには、反射部材８ａ〜８ｃは、斜め上方向き反射面と斜め下方向き反射面を有すればよく、例えば、垂直方向の断面形状が略三角形状に形成されたものであればよい。また、光発生受光装置９は、反射部材８ａ〜８ｃの斜め上方向き反射面に光を照射し、戻ってきた反射光を受光する第１の送受光器９ａと、反射部材８ａ〜８ｃの斜め下方向き反射面に光を照射し、戻ってきた反射光を受光する第２の送受光器９ｃを備えたものであればよい。   However, in order to detect the landing position of the car 1 and to detect a change in the weight of the car 1, the reflecting members 8a to 8c may have an obliquely upward reflecting surface and an obliquely downward reflecting surface. Any cross-sectional shape in the vertical direction may be formed in a substantially triangular shape. The light generating / receiving device 9 irradiates light on the obliquely upward reflecting surfaces of the reflecting members 8a to 8c, and receives the reflected light that has returned, and the slanting of the reflecting members 8a to 8c. What is necessary is just to have the 2nd light transmitter / receiver 9c which irradiates light to a reflective surface facing downward, and receives the reflected light which returned.

また、反射部材８ａ〜８ｃをかご１の前面上方部に設け、この反射部材８ａ〜８ｃに光を照射すると共に、戻ってきた反射光を受光する光発生受光装置９を設けた場合について説明したが、反射部材８ａ〜８ｃをかご１の前面下方部に設け、この反射部材８ａ〜８ｃに光を照射すると共に、戻ってきた反射光を受光する光発生受光装置９を設けてもよい。   Further, the case where the reflecting members 8a to 8c are provided in the upper front portion of the car 1, and the light generating and receiving device 9 that irradiates the reflecting members 8a to 8c and receives the reflected light that has returned is described. However, the reflecting members 8a to 8c may be provided in the lower part of the front surface of the car 1, and the light generating and receiving device 9 for irradiating the reflecting members 8a to 8c with light and receiving the returned reflected light may be provided.

以上のように、実施の形態１によれば、かごを精度よく着床させると共に、かごの着床検出と同時に戸開時の利用各や物の乗り降りに伴って発生するかご位置のずれを検出することにより、かご内重量の変動分を検出できるエレベーター制御装置が得られる。   As described above, according to the first embodiment, the car is accurately grounded, and at the same time when the car is detected, a shift in the position of the car that occurs when the door is opened or when an object gets on or off is detected. By doing so, an elevator control device capable of detecting the variation of the weight in the car is obtained.

実施の形態２．
次に、この発明の実施の形態２に係るエレベーター制御装置について説明する。実施の形態１では、反射部材８ａ〜８ｃと、反射部材８ａ〜８ｃに光を照射し、反射する光を受光する光発生受光装置９を備え、光発生受光装置９に設けられ、反射部材８ａ〜８ｃの斜め上方向き反射面に光を照射し、戻ってきた反射光を受光する第１の送受光器９ａと、反射部材８ａ〜８ｃの斜め下方向き反射面に光を照射し、戻ってきた反射光を受光する第２の送受光器９ｂを用いてかごを精度よく着床させると共に、かごの着床検出と同時に戸開時の利用各や物の乗り降りに伴って発生するかご位置のずれを検出することにより、かご内重量の変動分を検出できるエレベーター制御装置について図示説明した。実施の形態２では、実施の形態１に加え、かご扉の全開位置を検出できるエレベーター制御装置を説明するものである。 Embodiment 2.

Irradiates light to the obliquely upward reflecting surface of ˜8c and irradiates light to the obliquely downward reflecting surface of the first transmitter / receiver 9a that receives the reflected light and the reflecting members 8a to 8c, and returns. The second transmitter / receiver 9b that receives the reflected light is used to accurately land the car, and at the same time as detecting the landing of the car, the car position that is generated when the door is opened and when the car is moved on and off. The elevator control device that can detect the variation in the weight in the car by detecting the deviation has been illustrated and described. In the second embodiment, in addition to the first embodiment, an elevator control device capable of detecting the fully open position of the car door will be described.

図５は、実施の形態２に係るエレベーター制御装置を説明する構成図である。図５において、かご扉１１の前面上方部には、光発生受光装置９の第３の送受光器９ｃと垂直方向の断面形状が略台形状に形成された反射部材８ａ〜８ｃの垂直反射面との間の送受光を遮断する遮断部材、例えば遮蔽板２０が設けられている。図５の実線はかご扉１１が全閉状態で遮蔽板２０が送受光を遮断していない状態を示し、破線はかご扉１１が全開状態で遮蔽板２０が送受光を遮断している状態を示している。なお、その他の構成については、実施の形態１の図１および図２と同様に構成されているので、重複説明を省略する。   FIG. 5 is a configuration diagram illustrating the elevator control device according to the second embodiment. In FIG. 5, the vertical reflection surface of the reflecting members 8 a to 8 c having a substantially trapezoidal cross-sectional shape perpendicular to the third light transmitter / receiver 9 c of the light generating and receiving device 9 is formed in the upper front portion of the car door 11. A shielding member, for example, a shielding plate 20 is provided to block transmission / reception between the two. 5 indicates a state where the car door 11 is fully closed and the shielding plate 20 does not block transmission / reception, and a broken line indicates a state where the car door 11 is fully open and the shielding plate 20 blocks transmission / reception. Show. Other configurations are the same as those in FIG. 1 and FIG. 2 of the first embodiment, and thus redundant description is omitted.

実施の形態２に係るエレベーター制御装置は、前記のように構成されており、次にその動作について説明する。
かご１の着床時にかご扉１１の動作と連動し、かご扉１１が全開位置に達したときに、光発生受光装置９の第３の送受光器９ｃからの反射光は、遮蔽板２０により遮断される。光発生受光装置９の第３の送受光器９ｃからの反射光が遮蔽板２０で遮断されることにより、かご扉１１の全開位置を検出する。なお、その他の動作については実施の形態１と同様であり、重複説明を省略する。 The elevator control device according to the second embodiment is configured as described above, and the operation thereof will be described next.
In conjunction with the operation of the car door 11 when the car 1 is landed, when the car door 11 reaches the fully open position, the reflected light from the third light transmitter / receiver 9c of the light generating and receiving device 9 is reflected by the shielding plate 20. Blocked.
