Therefore, a detection object 24 made of a magnetic material is provided on each floor, and is configured to generate an ON signal from the first detector 22 when the detection object 24 and the first detector 22 approach each other. ing.
Moreover, the 2nd detector 32 which detects the rotation position of the motor 60 and generates a 2nd position detection signal is provided.

制御部５０は、第２検出器３２の第２位置検出信号、第１検出器２２の第１位置検出信号に基づいてかご７の位置制御信号を求める位置演算手段としての位置演算部５１と、被検出体２４の取付け誤差を測定するための階床位置学習モードを設定する運転モード設定部５４と、着床装置２０の被検出体２４の取付け誤差値を求める誤差演算部５５と、外部スイッチ３４からのオン信号に基づいて位置演算部５１を介して第２位置検出信号を記憶させると共に、上記誤差値を記憶する記憶手段としての記憶部５６と、第１位置検出信号(位置制御信号)を補正するために、記憶部５７に記憶された該誤差値に基づいて位置補正信号を位置・速度制御部５９を入力する位置補正手段としての位置補正部５７と、該位置補正信号によりモータ６０の位置・速度を制御する位置・速度制御部５９とを備えている。   The control unit 50 includes a position calculation unit 51 as a position calculation unit that obtains a position control signal of the car 7 based on the second position detection signal of the second detector 32 and the first position detection signal of the first detector 22; An operation mode setting unit 54 for setting a floor position learning mode for measuring the mounting error of the detected object 24, an error calculating unit 55 for determining an installation error value of the detected object 24 of the landing device 20, and an external switch The second position detection signal is stored via the position calculation unit 51 based on the ON signal from 34, and the storage unit 56 as a storage unit for storing the error value, and the first position detection signal (position control signal) Is corrected based on the error value stored in the storage unit 57, the position correction unit 57 as position correction means for inputting a position correction signal to the position / speed control unit 59, and the motor 60 using the position correction signal. Place of - and a position and speed control section 59 to control the speed.

制御部５０は、被検出体２４は取付け誤差が生じることを是認した上で、該誤差を取得して該誤差を補正するためのものである。これは、かご敷居７ａと各乗場敷居８ａ〜８ｃの高さが一致する位置に被検出体２４を取付けることが誤差ゼロであるが、該取付けに長時間かかることを防ぎながら、実質的にかご敷居７ａと各乗場敷居８ａ〜８ｃの高さが一致する位置に被検出体２４を取付けるためである。このため、取付け誤差Δxを下式により求めるものである。
Δx＝d／２−x ・・・・(１)
ここに、d：被検出体の長さ、x：第１位置検出信号がオフした位置 The control unit 50 is for obtaining the error and correcting the error after approving that the detected object 24 has an attachment error. Although it is zero error to attach the detected object 24 to a position where the height of the car sill 7a and each of the landing sills 8a to 8c coincide with each other, the car is substantially prevented while taking a long time for the attachment. This is because the detected object 24 is attached to a position where the height of the threshold 7a and the landing thresholds 8a to 8c coincide. For this reason, the attachment error Δx is obtained by the following equation.
Δx = d / 2−x (1)
Where d: length of the object to be detected, x: position where the first position detection signal is turned off

上記のように構成された着床装置２０における被検出体２４の取付け誤差の記憶部５６への設定について図１から図４を参照して説明する。
3階床（1階〜3階）のエレベーター１において、まず、かご７を最下階に停止させ、1階の乗場敷居８ａとかご敷居７ａとの高さが一致する位置にかご７を停止させる。次に、運転モード設定部５４を階床位置学習モードに設定し、位置演算部５１、位置補正部５７、位置・速度制御部５９を介してモータ６０を回転してかご７をゆっくりと上昇させる。 The setting of the mounting error of the detected object 24 in the storage unit 56 in the landing apparatus 20 configured as described above will be described with reference to FIGS.
In the elevator 1 on the third floor (1st to 3rd floors), firstly, the car 7 is stopped at the lowest floor, and the car 7 is stopped at a position where the height of the first floor landing sill 8a and the car sill 7a coincide. Let Next, the operation mode setting unit 54 is set to the floor position learning mode, and the car 60 is slowly raised by rotating the motor 60 via the position calculation unit 51, the position correction unit 57, and the position / speed control unit 59. .

かご７の運転中、位置演算部５１は第２検出器３２の第２位置検出信号に基づいてかご７の位置を演算し、着床装置２０の第２検出器２２からの第１位置検出信号がオンからオフすると、その変化した位置x1を記憶部５６に記憶する。誤差演算部５５は、１階における被検出体２４の上方向の取付け誤差Δx1を下式により求めて記憶部５６に記憶する。
Δx１＝d／2−x1 ・・・（２） During operation of the car 7, the position calculator 51 calculates the position of the car 7 based on the second position detection signal of the second detector 32, and the first position detection signal from the second detector 22 of the landing device 20. When is turned from ON to OFF, the changed position x1 is stored in the storage unit 56. The error calculation unit 55 calculates the upward mounting error Δx1 of the detected object 24 on the first floor by the following equation and stores it in the storage unit 56.
Δx1 = d / 2−x1 (2)

さらに、かご７を上昇させ、位置演算部５１は、第２検出器２２の第１位置検出信号がオンした位置y2を記憶し、次に２階の乗場敷居８bとかご敷居７aとの高さが一致する位置に停止させ、作業者がスイッチ３４をオンして、着床位置確定信号を制御部５０に送り、その時のかご位置y2を記憶部５６に記憶させる。さらにかご７を上昇させ、位置演算部５１は、第２検出器２２の第１位置検出信号がオンからオフした位置x2を記憶部５６に記憶する。誤差演算部５５は、2階の被検出体２４の上方向の取付け誤差Δx2および下方向の取付け誤差Δy2を求めて記憶部５６に記憶する。
Δx2＝d／2−x2 ・・・（３）
Δy2＝d／2−y2 ・・・（４）
なお、３階の被検出体２４についても、上記２階と同様にして取付け誤差を記憶部５６に記憶する。 Further, the car 7 is raised, and the position calculation unit 51 stores the position y2 at which the first position detection signal of the second detector 22 is turned on, and then the heights of the landing threshold 8b and the car threshold 7a on the second floor. Are stopped, the operator turns on the switch 34, sends a landing position determination signal to the control unit 50, and stores the car position y2 at that time in the storage unit 56. Further, the car 7 is raised, and the position calculation unit 51 stores in the storage unit 56 the position x2 at which the first position detection signal of the second detector 22 has been turned off. The error calculation unit 55 obtains the upward mounting error Δx2 and the downward mounting error Δy2 of the second floor detected object 24 and stores them in the storage unit 56.
Δx2 = d / 2−x2 (3)
Δy2 = d / 2−y2 (4)
Note that the attachment error is also stored in the storage unit 56 for the detected object 24 on the third floor in the same manner as the second floor.

上記のように構成された着床装置を用いてエレベーターの動作を図１から図４を参照して説明する。
いま、かご７を１階から２階に走行しようとすると、走行指令に基づいてモータ６０が回転し、かご７が上昇走行し、第２検出器３２が第２位置検出信号を発生し、位置演算部５１は、記憶部５７から１階と２階との階間距離を読み出して、該間階距離から第２位置検出信号に基づく走行距離を減算して、現在位置を求める。やがて、かご７が２階の近傍に到着すると、着床装置２０は、第１位置検出信号を発生し、位置演算部５１に入力する。位置補正部５７は、記憶部５６から２階の下方向の取付け誤差値Δy2を読み出して第２位置検出信号を補正した補正位置信号を求めて、該補正位置信号により位置・速度制御部５３を介してモータ６０を制御することによりかご７を走行する。 The operation of the elevator will be described with reference to FIGS. 1 to 4 using the landing apparatus configured as described above.
Now, when the car 7 is going to travel from the first floor to the second floor, the motor 60 rotates based on the travel command, the car 7 travels upward, the second detector 32 generates a second position detection signal, The calculation unit 51 reads the inter-floor distance between the first floor and the second floor from the storage unit 57, and subtracts the travel distance based on the second position detection signal from the inter-floor distance to obtain the current position. Eventually, when the car 7 arrives in the vicinity of the second floor, the landing device 20 generates a first position detection signal and inputs it to the position calculation unit 51. The position correction unit 57 reads the second floor downward installation error value Δy2 from the storage unit 56, obtains a corrected position signal by correcting the second position detection signal, and uses the corrected position signal to cause the position / speed control unit 53 to operate. The car 7 is driven by controlling the motor 60 via the motor.
