[0001] この発明は、ブレーキ回転体に対してブレーキシュ一を摩擦接触させることによりブ レーキ回転体の回転を制動し、力ごを停止させるエレベータのブレーキ装置に関す るものである。  TECHNICAL FIELD [0001] The present invention relates to an elevator brake device that brakes rotation of a brake rotator by bringing a brake shoe into frictional contact with the brake rotator to stop a force.
背景技術  Background art
[0002] 電動機や制御装置の容量低減や省エネを目的に、力ごの軽量ィ匕など電動機周り の低慣性ィ匕が進んでいる。最近では、歯車の無いギヤレス卷上機の普及により、電 動機軸換算の慣性質量はより小さくなる傾向にある。しかしながら、このような低慣性 化はブレーキ停止時の減速度を大きくすることにつながり、乗客に不快感を与えるこ とになる。また、力ご内負荷と走行方向による減速度の差が大きくなるため、非常停 止距離短縮と停止ショック低減を両立するようなブレーキ力の設定が難しくなつてい る。  [0002] For the purpose of reducing the capacity of an electric motor and a control device and saving energy, low inertia around the electric motor such as a light weight of a force is progressing. Recently, with the spread of gearless hoisting machines without gears, the inertial mass in terms of electric motor shaft tends to be smaller. However, such a low inertia leads to an increase in deceleration when the brake is stopped, which causes passengers to feel uncomfortable. In addition, since the difference between the internal load on the force and the deceleration depending on the direction of travel increases, it is difficult to set a braking force that achieves both shortening the emergency stop distance and reducing the stop shock.
これに対応するために様々な方法が提案されており、例えば特許文献 1のエレべ ータのブレーキ装置では、ブレーキ車の回転が第 1及び第 2電磁ブレーキにより選択 的に制動される構成としている。具体的には、上昇運転でかご内負荷が重負荷又は 下降運転で力ご内負荷が軽負荷の場合、急停止指令発生時に第 1及び第 2電磁ブ レーキの動作タイミングをずらすことで停止ショックを和らげている。また、上昇運転で かご内荷重が軽負荷又は下降運転でかご内負荷が重負荷の場合、第 1及び第 2電 磁ブレーキを同時に動作させて、必要な停止距離を確保することができる。  In order to cope with this, various methods have been proposed. For example, in the elevator brake device disclosed in Patent Document 1, the rotation of the brake car is selectively braked by the first and second electromagnetic brakes. Yes. Specifically, when the load in the car is heavy or the load in the force is light in the ascending operation, the stop shock is generated by shifting the operation timing of the first and second electromagnetic brakes when the sudden stop command is generated. Is relieved. In addition, when the load in the car is light or the load is heavy in the ascending operation, the first and second electromagnetic brakes can be operated simultaneously to ensure the necessary stopping distance.

In this example, a brake provided on a lifting machine that raises and lowers a car and a counterweight. Show the device.
[0009] 図において、ブレーキ回転体である円筒状のブレーキドラム 1には、駆動シーブが 同軸に設けられている。ブレーキドラム 1は、駆動シーブと一体的に回転される。駆動 シーブには、力ご及び釣合おもりを吊り下げる主索が巻き掛けられている。かご及び 釣合おもりは、駆動シーブが回転されることにより昇降路内を昇降される。 In the figure, a cylindrical brake drum 1 that is a brake rotating body is provided with a drive sheave coaxially. The brake drum 1 is rotated integrally with the drive sheave. The drive sheave is wrapped with a main rope that suspends the force and counterweight. The car and the counterweight are moved up and down in the hoistway by rotating the drive sheave.
[0010] ブレーキドラム 1の内側には、卷上機の固定部に対して固定されたインナフレーム 2 が設けられている。インナフレーム 2には、一対（図では一方のみ示す）の電磁マグネ ット 3が固定されている。各電磁マグネット 3は、インナフレーム 2に固定された固定鉄 心 4と、固定鉄心 4に固定されたブレーキコイル 5とを有している。  [0010] Inside the brake drum 1, an inner frame 2 fixed to a fixed portion of the lifting machine is provided. A pair (only one is shown in the figure) of electromagnetic magnets 3 is fixed to the inner frame 2. Each electromagnetic magnet 3 has a fixed iron core 4 fixed to the inner frame 2 and a brake coil 5 fixed to the fixed iron core 4.
[0011] 各固定鉄心 4には、可動鉄心 6が接離される。各可動鉄心 6には、ブレーキドラム 1 の内周面に接離されるブレーキシュ一 7が連結されている。各固定鉄心 4には、可動 鉄心 6を押圧してブレーキシュ一 7をブレーキドラム 1の内周面に押し付ける複数のブ レーキばね 8が設けられて!/、る。  [0011] Each fixed iron core 4 is in contact with or separated from the movable iron core 6. Each movable iron core 6 is connected to a brake shoe 7 that is in contact with and separated from the inner peripheral surface of the brake drum 1. Each fixed iron core 4 is provided with a plurality of brake springs 8 that press the movable iron core 6 and press the brake shoe 7 against the inner peripheral surface of the brake drum 1!
[0012] ブレーキドラム 1の回転は、ブレーキシュ一 7がブレーキドラム 1の内周面に押し付 けられることにより摩擦制動される。また、電磁マグネット 3を励磁することにより、可動 鉄心 6がブレーキばね 8に抗して固定鉄心 4側に吸引され、ブレーキシュ一 7がブレ ーキドラム 1の内周面から開離される。これにより、ブレーキドラム 1に対する制動力が 解除される。  The rotation of the brake drum 1 is frictionally braked by the brake shoe 7 being pressed against the inner peripheral surface of the brake drum 1. Further, by exciting the electromagnetic magnet 3, the movable iron core 6 is attracted to the fixed iron core 4 side against the brake spring 8, and the brake shoe 7 is separated from the inner peripheral surface of the brake drum 1.

また、力ご及び釣合おもりの停止中は、ブレーキドラム 1の回転が制動されている（静 止保持)。さらに、かご及び釣合おもりの昇降中に非常停止指令が発生すると、卷上 機モータへの通電が遮断されるとともに、ブレーキコイル 5への通電が遮断される。こ れにより、ブレーキドラム 1にブレーキシュ一 7が押し付けられ、ブレーキドラム 1及び 駆動シーブの回転が制動され、かご及び釣合おもりが非常停止される。 Also, while the force and counterweight are stopped, the rotation of the brake drum 1 is braked (holding still). Further, when an emergency stop command is generated while the car and the counterweight are being raised and lowered, the energization to the lifting machine motor is interrupted and the energization to the brake coil 5 is also interrupted. As a result, the brake shoe 7 is pressed against the brake drum 1, and the brake drum 1 and The rotation of the drive sheave is braked and the car and the counterweight are emergency stopped.
[0014] インナフレーム 2には、制動時にブレーキドラム 1からブレーキシュ一 7に作用する 回転トルクを受ける複数のトルク受け部 9が設けられている。各トルク受け部 9には、 ブレーキシュ一 7の端部が当接するトルク受け面 9aが設けられている。  [0014] The inner frame 2 is provided with a plurality of torque receiving portions 9 for receiving rotational torque acting on the brake shoe 7 from the brake drum 1 during braking. Each torque receiving portion 9 is provided with a torque receiving surface 9a with which the end of the brake shoe 7 abuts.
[0015] 各トルク受け部 9には、非常制動時にブレーキドラム 1の回転方向（周方向）にブレ 一キシュ一 7を振動させる振動ァクチユエータ 10が埋設されている。逆に言うと、ブレ 一キシュ一 7は、振動ァクチユエータ 10から加振されることにより、ブレーキドラム 1の 回転方向に微小に振動可能となっている。また、非常制動時には、ブレーキドラム 1 の回転方向に応じて、ブレーキシュ一 7からトルクを受けているトルク受け部 9に設け られた振動ァクチユエータ 10によりブレーキシュ一 7が振動される。  [0015] Each torque receiving portion 9 is embedded with a vibration actuator 10 that vibrates the brake 7 in the rotation direction (circumferential direction) of the brake drum 1 during emergency braking. Conversely, the brake 7 can be vibrated minutely in the rotational direction of the brake drum 1 by being vibrated from the vibration actuator 10. Further, during emergency braking, the brake shoe 7 is vibrated by the vibration actuator 10 provided in the torque receiving portion 9 receiving torque from the brake shoe 7 according to the rotation direction of the brake drum 1.
[0016] 振動ァクチユエータ 10としては、例えば圧電素子が用いられている。また、振動ァク チユエータ 10は、かご起動時にはブレーキシュ一 7からトルク受け部 9が受ける圧力 に応じた電気信号をエレベータ制御装置に出力する。エレベータ制御装置は、かご 起動時には、トルク受け部 9の圧力がゼロとなるように卷上機にトルクを発生させた状 態でブレーキシュ一 7をブレーキドラム 1から開離させる。即ち、振動ァクチユエータ 1 0は、起動用秤装置としても機能する。  [0016] As the vibration actuator 10, for example, a piezoelectric element is used. Further, the vibration actuator 10 outputs an electrical signal corresponding to the pressure received by the torque receiving portion 9 from the brake shoe 7 to the elevator control device when the car is started. When the car is started, the elevator control device releases the brake shoe 7 from the brake drum 1 in a state where torque is generated in the hoisting machine so that the pressure of the torque receiving portion 9 becomes zero. That is, the vibration actuator 10 also functions as a starting scale device.
[0017] インナフレーム 2には、振動ァクチユエータ 10を制御する複数の振動制御部 11、及 びブレーキドラム 1の回転速度もしくはドラム面の移動速度を検出する複数の速度セ ンサ 12が設けられている。これらの振動制御部 11及び速度センサ 12は、対応する 振動ァクチユエータ 10の近傍に配置されている。また、速度センサ 12は、ブレーキド ラム 1の回転により発電する交流発電機を兼ねて 、る。  The inner frame 2 is provided with a plurality of vibration controllers 11 for controlling the vibration actuator 10 and a plurality of speed sensors 12 for detecting the rotational speed of the brake drum 1 or the moving speed of the drum surface. . These vibration control unit 11 and speed sensor 12 are arranged in the vicinity of the corresponding vibration actuator 10. The speed sensor 12 also serves as an AC generator that generates electric power by the rotation of the brake drum 1.
[0018] 振動制御部 11は、非常制動時に、速度センサ 12からの信号に応じて振動ァクチュ エータ 10の振動の振幅及び周波数を制御し、ブレーキドラム 1の回転方向へのブレ ーキドラム 1とブレーキシュ一 7との速度差を制御する。また、非常制動時には、振動 制御部 11は、ブレーキシュ一 7がブレーキドラム 1に接触した後に振動ァクチユエ一 タ 10を振動させるとともに、ブレーキシュ一 7が制動動作を開始して力もブレーキドラ ム 1に接触するまでの間にも振動ァクチユエータ 10を振動させる。  [0018] During emergency braking, the vibration control unit 11 controls the amplitude and frequency of vibration of the vibration actuator 10 according to the signal from the speed sensor 12, and the brake drum 1 and the brake shoe in the rotation direction of the brake drum 1 are controlled. Control the speed difference from 1. During emergency braking, the vibration control unit 11 causes the vibration actuator 10 to vibrate after the brake shoe 7 contacts the brake drum 1, and the brake shoe 7 starts the braking operation so that the force is applied to the brake drum 1. The vibration actuator 10 is also vibrated until it touches.
[0019] 図 2は図 1の要部を示すブロック図である。振動ァクチユエータ 10及び振動制御部 11には、図 2の破線で示すように、交流発電機を兼ねる速度センサ 12により発電さ れた電力が供給される。 FIG. 2 is a block diagram showing a main part of FIG. Vibration actuator 10 and vibration controller As shown by the broken line in FIG. 2, the electric power generated by the speed sensor 12 also serving as an AC generator is supplied to 11.
[0020] 図 3は図 1のブレーキ装置の非常制動中のある時間領域における制御の様子を示 すグラフである。具体的には、図 3の上段のグラフは、ブレーキドラム 1のブレーキシュ 一 7との接触部分の速度 Vm及びブレーキシュ一 7の速度 Vsを示している。図 3の中 段のグラフは、 Vsと Vmとの速度差を示している。図 3の下段のグラフは、ブレーキド ラム 1が受ける制動力 Fを示している。  FIG. 3 is a graph showing a state of control in a certain time region during emergency braking of the brake device of FIG. Specifically, the upper graph in FIG. 3 shows the speed Vm of the contact portion of the brake drum 1 with the brake shoe 7 and the speed Vs of the brake shoe 7. The middle graph in Fig. 3 shows the speed difference between Vs and Vm. The lower graph in Fig. 3 shows the braking force F applied to the brake drum 1.
[0021] なお、速度 Vm、 Vsの値は、ブレーキドラム 1の速度の方向を正としている。また、制 動力 Fの値は、ブレーキドラム 1を停止させる方向に働く場合を正としている。さらに、 図 3に示した時間領域は、概ね振動の 1周期 TO中の変化を示したものである。  Note that the values of the speeds Vm and Vs are positive in the direction of the speed of the brake drum 1. The value of the braking force F is positive when it works in the direction to stop the brake drum 1. Furthermore, the time domain shown in Fig. 3 shows the change during one period TO of vibration.
[0022] 制動開始後、ブレーキシュ一 7は、振動ァクチユエータ 10により、以下のような速度 Vsで振動される。  [0022] After the start of braking, the brake shoe 7 is vibrated by the vibration actuator 10 at the following speed Vs.
Vs = f (t)  Vs = f (t)
J T0f (t) dt = O J T0 f (t) dt = O
0  0
ここで、 tは振動ァクチユエータ 10の駆動開始からの時間、関数 f (t)は周期 TOの周 期関数である。  Here, t is the time from the start of driving of the vibration actuator 10, and the function f (t) is a periodic function of the period TO.
[0023] また、周期 TOの間に Vs>Vmとなる区間 a〜bが存在するように設定されている。こ のため、区間 a〜bとその他の区間とでは、速度差 (Vs—Vm)の符号が逆になる。ま た、ブレーキドラム 1に付与される制動力の大きさ FOは、ブレーキシュ一 7の押し付け 力を P、ブレーキドラム 1とブレーキシュ一 7との摩擦係数を とすると、次式で表され る。  [0023] Further, the interval a to b where Vs> Vm exists between the periods TO. For this reason, the sign of the speed difference (Vs−Vm) is reversed between sections ab and other sections. The magnitude FO of the braking force applied to the brake drum 1 is expressed by the following equation, where P is the pressing force of the brake shoe 7 and the friction coefficient between the brake drum 1 and the brake shoe 7. .
FO = P- μ  FO = P- μ
[0024] 従って、区間 a〜b以外ではブレーキドラム 1に正の制動力 FOが働くのに対して、区 間 a〜bではブレーキドラム 1に負の制動力一 FOが働くことになる。  Accordingly, a positive braking force FO acts on the brake drum 1 outside the sections a to b, whereas a negative braking force 1 FO acts on the brake drum 1 in the sections a to b.
[0025] ここで、 Vsの 1周期に相当する時間 TOの間の平均的な制動力 Faは、次式で表さ れる。  Here, an average braking force Fa during a time TO corresponding to one cycle of Vs is expressed by the following equation.
Fa = FO- (T0- 2-Td) /TO  Fa = FO- (T0- 2-Td) / TO
Td：負の制動力となる時間間隔 [0026] また、ブレーキシュ一 7を振動させた場合と振動させな 、場合とを比較すると、次式 が成り立つ。 Td: Time interval for negative braking force [0026] Further, when the case where the brake shoe 7 is vibrated is compared with the case where it is not vibrated, the following equation is established.
FO >Fa= -FO  FO> Fa = -FO
但し、 0<痫< 1  Where 0 <痫 <1
[0027] 上記の痫は、制動力の変化率を表す係数である。従って、ブレーキシュ一 7を速度 Vsで振動させることにより、平均的な制動力を低減できるとともに、負の制動力となる 時間間隔 Tdを変えることで制動力を制御することができる。例えば、振動ァクチユエ ータの振動パターン (変位)が、振幅 A、周波数 ωの正弦波で表されるとすると、振動 速度の振幅は ω Αとなるので、ブレーキシュ一 7の振動速度 Vsを変えるためには振 幅 A又は周波数 ω、もしくは両方を変えればよい。  [0027] The above 痫 is a coefficient representing the rate of change of the braking force. Therefore, the average braking force can be reduced by vibrating the brake shoe 7 at the speed Vs, and the braking force can be controlled by changing the time interval Td that becomes a negative braking force. For example, if the vibration pattern (displacement) of the vibration actuator is expressed by a sine wave with an amplitude A and a frequency ω, the vibration speed amplitude is ω 、, so the vibration speed Vs of the brake shoe 7 is changed. To do this, change the amplitude A, the frequency ω, or both.
[0028] 上記の説明では周期 TOの間について説明した力 実際にはブレーキドラム 1が停 止するまで、連続的に振動ァクチユエータ 10を駆動する。この間、ブレーキドラム 1が 減速されるが、これは図 3の VOが減少することに相当する。このため、振動ァクチュ エータ 10の駆動パターンを一定とすると、 Vs >Vmとなる時間間隔 Tdが増加し、制 動力 Faは減少していく。  [0028] In the above description, the force described during the period TO is actually driven by the vibration actuator 10 until the brake drum 1 stops. During this time, brake drum 1 is decelerated, which corresponds to a decrease in VO in Fig. 3. Therefore, if the drive pattern of the vibration actuator 10 is constant, the time interval Td where Vs> Vm increases, and the braking force Fa decreases.
[0029] このため、所望の Faを得るためには、所定の制動力を付与した場合のブレーキドラ ム 1の速度変化を予め算出しておき、これに基づき振動周期毎に所定の Tdの値が得 られるように振動パターンを設定しておけばよい。さらに、速度 Vmに対する所望の F aを得るための振動パターンが決まれば、 Vmの変化に比例して振動パターンの周波 数 ωもしくは振幅 Αを変化させることで、ブレーキトルクを Faに保つ。  [0029] Therefore, in order to obtain a desired Fa, the speed change of the brake drum 1 when a predetermined braking force is applied is calculated in advance, and based on this, a predetermined Td value is obtained for each vibration cycle. The vibration pattern should be set so that Furthermore, once the vibration pattern to obtain the desired Fa for the speed Vm is determined, the brake torque is kept at Fa by changing the frequency ω or amplitude の of the vibration pattern in proportion to the change in Vm.
[0030] 上記のようなエレベータのブレーキ装置では、非常制動時に振動ァクチユエータ 1 0によりブレーキシュ一 7が振動されるので、非常停止時の減速度をより適当に制御 することができ、停止ショックを緩和して乗り心地を改善することができる。また、振動 ァクチユエータ 10は、トルク受け部 9に設けられているので、ブレーキシュ一 7をブレ ーキドラム 1の回転方向へ効率良く振動させることができる。  [0030] In the elevator brake device as described above, the brake actuator 10 is vibrated by the vibration actuator 10 during emergency braking, so that the deceleration during emergency stop can be controlled more appropriately, and stop shock can be prevented. You can relax and improve your ride. Further, since the vibration actuator 10 is provided in the torque receiving portion 9, the brake shoe 7 can be vibrated efficiently in the rotation direction of the brake drum 1.
[0031] また、振動ァクチユエータ 10は、起動用秤装置としても機能するので、起動用秤装 置を別途設置する必要が無く、コストを削減することができる。  [0031] Further, since the vibration actuator 10 also functions as a starting scale device, it is not necessary to separately install the starting scale device, and the cost can be reduced.
さらに、非常制動時には、振動制御部 11は、ブレーキシュ一 7が制動動作を開始し て力もブレーキドラム 1に接触するまでの間にも振動ァクチユエータ 10を振動させる ので、ブレーキシュ一 7とトルク受け面 9aとの間の摩擦抵抗が小さくなり、制動トルクを 素早く立ち上げることができるとともに、トルク受け面 9a及びブレーキシュ一 7の摩耗 を減らすことができる。 Furthermore, during emergency braking, the vibration control unit 11 causes the brake shoe 7 to start the braking operation. Since the vibration actuator 10 is vibrated before the force and the brake drum 1 are contacted, the frictional resistance between the brake shoe 7 and the torque receiving surface 9a is reduced, and the braking torque can be quickly started up. Further, wear of the torque receiving surface 9a and the brake shoe 7 can be reduced.
[0032] さらにまた、振動ァクチユエータ 10の近傍に速度センサ 12を設け、振動制御部 11 は、速度センサ 12からの信号に応じて振動ァクチユエータ 10の振動の振幅及び周 波数を制御し、ブレーキドラム 1の回転方向へのブレーキドラム 1とブレーキシュ一 7と の速度差を制御するので、速度差が正力負かの時間的割合を制御して、非常停止 時の減速度をより適当に制御することができる。  Furthermore, a speed sensor 12 is provided in the vicinity of the vibration actuator 10, and the vibration control unit 11 controls the amplitude and frequency of vibration of the vibration actuator 10 in accordance with a signal from the speed sensor 12, and the brake drum 1 The speed difference between the brake drum 1 and the brake shoe 7 in the direction of rotation is controlled, so the time ratio of whether the speed difference is positive or negative is controlled to control the deceleration at emergency stop more appropriately. be able to.
[0033] また、ブレーキドラム 1の回転により発電する交流発電機 (速度センサ 12)を設け、 発電機により振動ァクチユエータ 10に電力を供給するので、他の制御電源力も独立 した電源を確保し、制動中に常に電力を供給することができる。この場合、発電電圧 周波数を振動パターンの周波数 ωとして用いることで、制動によってブレーキドラム 1 が減速することに伴って、振動パターンの周波数 ωを自動的に下げることができ、減 速中にも制動力を一定に保つことができる。 [0033] In addition, an AC generator (speed sensor 12) that generates electricity by the rotation of the brake drum 1 is provided, and power is supplied to the vibration actuator 10 by the generator. Power can always be supplied inside. In this case, by using the generated voltage frequency as the vibration pattern frequency ω, the vibration pattern frequency ω can be automatically reduced as the brake drum 1 decelerates due to braking, and the vibration pattern is also controlled during deceleration. Power can be kept constant.
さらに、振動ァクチユエータ 10として圧電素子を用いたので、振動ァクチユエータ 1 0を小型化することができる。圧電素子が電圧駆動であるため、交流発電機の発電電 圧によって直接駆動することができ、振動制御部 11を簡略ィ匕することができる。  Furthermore, since a piezoelectric element is used as the vibration actuator 10, the vibration actuator 10 can be reduced in size. Since the piezoelectric element is voltage driven, it can be directly driven by the generated voltage of the AC generator, and the vibration control unit 11 can be simplified.
[0034] なお、発電機として直流発電機を用いてもよ!ヽ。この場合、発電電圧信号をブレー キ回転体の回転検出信号として用いることができる。 [0034] A DC generator may be used as the generator! In this case, the generated voltage signal can be used as a rotation detection signal for the brake rotor.
また、速度センサは、卷上機を駆動させるための速度センサと共用してもよい。 さらに、卷上機モータの回転軸の回転を検出するモータエンコーダ力 の信号を用 V、て振動ァクチユエータを制御してもよ 、。  Moreover, you may share a speed sensor with the speed sensor for driving a hoisting machine. In addition, the vibration actuator can be controlled using the motor encoder force signal V, which detects the rotation of the rotary shaft of the hoisting machine motor.
[0035] さらにまた、ブレーキシュ一はブレーキドラムの外側に設けてもよい。 [0035] Furthermore, the brake shoe may be provided outside the brake drum.
また、ブレーキ回転体はブレーキディスクであってもよい。即ち、ブレーキ装置は、 ディスクブレーキであってもよ 、。  The brake rotating body may be a brake disc. That is, the brake device may be a disc brake.
さらに、上記の例では、ブレーキ装置を卷上機に設けた力 例えば吊り車、返し車 又はそらせ車など、他の場所に設けてもよい。 さらにまた、振動ァクチユエータは、ブレーキシュ一側に搭載したり、ブレーキシュ一 の可動鉄心への連結部に設けたりしてもよい。 Furthermore, in the above example, the brake device may be provided in another place such as a force provided on the lifting machine, for example, a suspended wheel, a return wheel, or a deflector. Furthermore, the vibration actuator may be mounted on one side of the brake shoe or may be provided at a connecting portion to the movable iron core of the brake shoe.
