  • an elevator apparatus includes: a car; a first brake device and a second brake device for braking running of the car; and a brake control portion for controlling operations of the first brake device and the second brake device.
  • the brake control portion first causes the first brake device to perform braking operation when a sudden stop command for making a sudden stop of the car is issued, and the brake control portion causes the second brake device to perform braking operation when a deceleration of the car is equal to or smaller than a predetermined value after a lapse of a predetermined time.
  • Fig. 1 is a schematic diagram showing an elevator apparatus according to Embodiment 1 of the present invention.
  • the hoisting machine 4 has a drive sheave 5 around which the main rope 3 is looped, a motor 6 for rotating the drive sheave 5, and braking means 7 for braking rotation of the drive sheave 5.
  • the braking means 7 has a brake pulley 8 rotated integrally with the drive sheave 5, a first brake device 9 and a second brake device 10 for braking rotation of the brake pulley 8.
  • the first brake device 9 has a first brake shoe 11 to be brought into contact with and away from the brake pulley 8, a first brake spring (not shown) for pressing the first brake shoe 11 against the brake pulley 8, and a first brake release coil 12 for causing the first brake shoe 11 to be spaced away from the brake pulley 8 against the first brake spring.

  • the sudden stop command and the emergency stop command are issued by a safety monitoring device for monitoring the safety of the elevator apparatus or the like, and input to the brake control portion 20.
  • the sudden stop command is issued when the speed detector 15 has broken down, when the power conversion device 17 has broken down, or when an excessive speed or the like of the car 1 has been detected. That is, the sudden stop command is issued when the motor 6 cannot be controlled but the brake devices 9 and 10 can be controlled. Accordingly, when the sudden stop command is issued, the power supplied to the motor 6 is swiftly shut off.
  • the emergency stop command is issued when, for example, the car 1 has reached a terminal end of the hoistway.
  • the elevator control device 18 is constituted by a computer having a calculation processing portion (CPU), a storage portion (a ROM, a RAM, a hard disk, and the like), and signal input/output portions.

  • Fig. 2 is a circuit diagram showing a control circuit of the first brake device 9 and the second brake device 10 of Fig. 1 .
  • the first brake release coil 12 and the second brake release coil 14 are connected in parallel with each other with respect to a power supply 21.
  • a first contact 22 is connected in series to the first brake release coil 12. When the first contact 22 is closed, power is supplied to the first brake release coil 12, so the first brake device 9 is released. When the first contact 22 is opened, the power supplied to the first brake release coil 12 is shut off, so the first brake device 9 performs braking operation.
  • a second contact 23 is connected in series to the second brake release coil 14. When the second contact 23 is closed, power is supplied to the second brake release coil 14, so the second brake device 10 is released. When the second contact 23 is opened, the power supplied to the second brake release coil 14 is shut off, so the second brake device 10 performs braking operation.
  • a first diode 24 and a first electrical resistor 25 are connected in parallel to the first brake release coil 12.
  • a circuit composed of the first diode 24 and the first electrical resistor 25 protects the brake control portion 20 from a back electromotive force generated in the first brake release coil 12 upon the opening of the first contact 22.
  • a second diode 26 and a second electrical resistor 27 are connected in parallel to the second brake release coil 14.
  • a circuit composed of the second diode 26 and the second electrical resistor 27 protects the brake control portion 20 from a back electromotive force generated in the second brake release coil 14 upon the opening of the second contact 23.
  • Fig. 3 is a flowchart showing an operation of the brake control portion 20 of Fig. 1 .
  • the brake control portion 20 repeatedly performs an operation shown in Fig. 3 on a predetermined cycle.
  • the brake control portion 20 monitors whether or not the car 1 is stopped (step S1), whether or not an emergency stop command has been issued (step S2), and whether or not a sudden stop command has been issued (step S3).
  • the brake control portion 20 sets a counter value to 0 (step S4).
  • the brake control portion 20 outputs a command to turn the first contact 22 and the second contact 23 off (step S5).
  • the brake control portion 20 terminates the current round of processings. That is, the brake control portion 20 allows the car 1 to keep running.
  • the brake control portion 20 When the car 1 is running, the emergency stop command has not been issued, and the sudden stop command has been issued, the brake control portion 20 outputs a command to turn the first contact 22 off (step S6), and applies 1 to the counter value (step S7). After that, the brake control portion 20 determines whether or not the counter value has reached a set value t1 that has been set in advance, namely, whether or not a predetermined time has elapsed after the outputting of the command to turn the first contact 22 off in response to the sudden stop command (step S8). When the counter value has not reached the set value t1 (cnt ⁇ t1), the brake control portion 20 terminates the current round of the processings.
  • the brake control portion 20 determines whether or not the acceleration of the car 1 is equal to or larger than a threshold ⁇ L (step S9). In other words, the brake control portion 20 determines whether or not the deceleration of the car 1 is equal to or smaller than a predetermined value.
  • the acceleration of the car 1 can be calculated by subjecting a speed calculated based on a signal from the speed detector 15 to a differential processing or a bypass filter processing.
  • the brake control portion 20 terminates the current round of the processing. That is, the brake control portion 20 continues the monitoring operation while holding the first contact 22 open and the second contact 23 closed.
  • the brake control portion 20 outputs a command to turn the second contact 23 off (step S10)
  • Fig. 4 is a timing chart showing a relationship among the speed of the car, the acceleration of the car, the state of the first contact 22, and the state of the second contact 23 in the event of the issuance of a sudden stop command during regenerative operation of the elevator apparatus of Fig. 1 .
  • the speed is indicated on the assumption that the traveling direction of the car 1 is positive.
  • a gravitational acceleration acts in such a direction that the car 1 cannot be stopped with ease, as in a case where the car 1 is being raised with no load applied thereto or a case where the car 1 is being lowered in a packed state.
  • the second contact 23 is opened, and a braking force generated by the second brake device 10 is also applied.
  • the car 1 cannot be stopped with ease during regenerative operation, so the deceleration of the car 1 does not become excessive even when both the first brake device 9 and the second brake device 10 are caused to perform braking operation.
  • Fig. 5 is a timing chart showing a relationship among the speed of the car, the acceleration of the car, the state of the first contact 22, and the state of the second contact 23 in the event of the issuance of a sudden stop command during power running operation of the elevator apparatus of Fig. 1 .
  • the gravitational acceleration acts in such a direction that the car 1 can be stopped with ease, as in a case where the car 1 is being lowered with no load applied thereto or a case where the car 1 is being raised in a packed state.
  • the acceleration of the car 1 is smaller than the threshold ⁇ L at the time point t1, so the monitoring of the acceleration is continuously performed.
  • the second contact 23 is opened, and a braking force generated by the second brake device 10 is also applied.
  • the elevator apparatus is operated in such a direction that the car 1 can be stopped with ease. It is therefore possible to prevent the deceleration of the car 1 from becoming excessive and alleviate a feeling of discomfort of passengers within the car 1 by monitoring the acceleration of the car 1 and decelerating the car 1 mainly with the aid of only the braking force generated by the first brake device 9. Further, the braking force generated by the second brake device 10 is applied when the car 1 has decelerated sufficiently. In stopping the car 1 completely, therefore, the first brake 9 and the second brake 10 can bring the car 1 to a halt more reliably. That is, the elevator apparatus according to Embodiment 1 can prevent the deceleration of the car 1 from becoming excessive in the event of issuance of a sudden stop command with a simple configuration.
  • Fig. 6 is a timing chart showing a relationship among the speed of the car 1, the acceleration of the car 1, the state of the first contact 22, and the state of the second contact 23 in the event of the issuance of an emergency stop command in the elevator apparatus of Fig. 1 .
  • the emergency stop command is issued at the time point t1
  • the first contact 22 and the second contact 23 are opened simultaneously and immediately. Braking forces are thereby simultaneously generated by the first brake device 9 and the second brake device 10, so the car 1 is stopped swiftly.
  • the first brake device 9 and the second brake device 10 are caused to perform braking operation simultaneously.
  • the car 1 can be stopped under a smaller impact than in a case where the car 1 has collided with a shock absorber (not shown) installed at the terminal end.
  • the acceleration of the car 1 is calculated from an output of the speed detector 15 provided on the hoisting machine 4.
  • the acceleration of the car may be calculated from an output of a speed detector provided at another location, for example, on a speed governor or the car.
  • the brake control portion 20 is provided to perform some of the functions of the elevator control device 18.
  • the brake control portion 20 may be provided on another device, for example, the safety monitoring device for monitoring the safety of the elevator device.
  • the brake control portion may be configured as a device independent of the elevator control device and the safety monitoring device.
  • the function of the brake control portion can also be realized by an electrical circuit for processing analog signals.
  • the hoisting machine 4 is provided with the first brake device 9 and the second brake device 10.
  • the first brake device 9 and the second brake device 10 may be provided at another location. That is, the first brake device 9 and the second brake device 10 may each be designed as, tor example, a car brake mounted on the car, a rope brake for gripping the main rope to brake the car, or the like.
  • first brake device and the second brake device may be disposed at different locations.
  • the two brake devices 9 and 10 are employed.
  • three or more brake devices may be employed.
  • the brake devices may be divided into a first group and a second group to perform a control operation similar to that of Embodiment 1 of the present invention.
