The first detection means 18 determines whether or not the car 1 is currently stopped based on the car position information acquired from the operation control means 11 (S101). If the car 1 is stopped (Yes in S101), the first detection means 18 determines whether the photoelectric sensor 17-Ax1 or 17-Ay1 has been operated (S102).
- the detection light emitted from the projector 17a enters the corresponding light receiver 17b. For this reason, the photoelectric sensors 17-Ax1 and 17-Ay1 do not operate (No in S102). When the photoelectric sensors 17-Ax1 and 17-Ay1 are not operating, the first detection unit 18 returns to the process of S101.
- the first detection means 18 invalidates the operations of the photoelectric sensors 17-Ax1 and 17-Ay1 (S103). For this reason, while the car 1 is traveling, the first detection means 18 does not detect the shake of the main rope 3.

- the first detection means 18 detects that the first level of vibration has occurred in the main rope 3 (S106). That is, FIG. 4 shows a case where the first detection means 18 detects that the first level swing has occurred in the main rope 3 based on the value of the first level counter.
- the value of the first level counter corresponds to the number of times the detection light emitted from the light projector 17a of the photoelectric sensor 17-Ax1 or the light projector 17a of the photoelectric sensor 17-Ay1 is interrupted while the car 1 is stopped.
- the first detection means 18 outputs a first detection signal to the detection device 9 when detecting that the first level of vibration has occurred in the main rope 3.
- the first detection means 18 If the value of the first level counter is less than the reference value in S105, the first detection means 18 returns to the process of S101.
- FIG. 5 is a flowchart for explaining another operation of the detection device 9.
- FIG. 5 shows operations of the second detection means 19 during normal operation and control operation.
- the second detection means 19 acquires the car position information detected by the car position detection means 10 from the operation control means 11.
- the second detection means 19 determines whether or not the car 1 is currently stopped based on the car position information acquired from the operation control means 11 (S201).
- the second detection means 19 determines whether or not the first detection means 18 detects the first level of shake (S202). If the first detection means 18 has not detected the first level shake, the second detection means 19 returns to the process of S201.
- the second detection means 19 invalidates the operations of the photoelectric sensors 17-Ax2 and 17-Ay2 (S203). For this reason, while the car 1 is traveling, the second detection means 19 does not detect the swing of the main rope 3. Even if the detection light is blocked by the traveling car 1, the second detection means 19 will not malfunction.
- the second detection means 19 determines whether the photoelectric sensor 17-Ax2 or 17-Ay2 has been operated. (S204).
- the photoelectric sensor 17-Ax2 When the shake of the main rope 3 is further increased after the first level of shake is detected and the detection light emitted from the projector 17a of the photoelectric sensor 17-Ax2 is blocked by the main rope 3, the photoelectric sensor 17-Ax2 The light receiver 17b outputs a non-light receiving signal.

- the second detection means 19 returns to the process of S201.
- FIG. 6 is a flowchart for explaining the operation of the control device 8.
- FIG. 6 shows a series of operations from the transition from the normal operation to the control operation until the return to the normal operation.
- the elevator apparatus is a shuttle elevator in which the effects of the present invention are remarkably exhibited.
- the car 1 reciprocates between the terminal 12 on the upper terminal floor and the terminal 12 on the lower terminal floor.
- the operation control means 11 controls normal operation in which the car 1 sequentially responds to registered calls.
- the operation control means 11 periodically determines whether or not the first level swing of the main rope 3 has been detected by the first detection means 18 (S301). Even if the main rope 3 swings, if the value of the first level counter is smaller than the reference value, the swing of the first level is not detected. Further, while the car 1 is traveling, the first level of shake is not detected. If the first detection signal is not received from the first detection unit 18 (No in S301), the operation control unit 11 continues the normal operation (S302).
- the operation control means 11 shifts the elevator to control operation in order to prevent damage due to long-period vibration (S303). .
- the first detection means 18 detects the first-level shake when the car 1 is stopped at the terminal 12 on the upper terminal floor or the terminal 12 on the lower terminal floor. For this reason, when the elevator shifts to the control operation, the car 1 is stopped at any terminal floor.
- the floor where the car 1 is stopped when shifting to the control operation is also referred to as a transition stop floor.
- the stop floor at the time of transition is the stop floor of the car 1 when the first level run-out is first detected.
- the operation control means 11 makes the car 1 respond to the registered call even after the elevator is shifted to the control operation.
- the operation control means 11 provides restrictions for some functions and performs forcible management as necessary.
- the distance of the main rope 3 where the movement is not restrained does not change.
- the distance between the end portion of the main rope 3 connected to the car 1 and the portion wound around the drive sheave does not change. For this reason, if the car 1 continues to stop after the first detection means 18 detects the first level of swing, the swing of the main rope 3 may increase.
- the operation control means 11 shifts the elevator to the control operation, it first determines whether or not the door is currently open. If the door is open on the stop floor at the time of transition, the operation control means 11 starts an operation for forcibly closing the door (hereinafter also referred to as “door closing forced operation”) (S304).
- the door closing forced operation is an operation for forcibly starting the door closing operation. If the condition for preventing the door closing is not established, if the door is being opened in S304, the operation control means 11 forcibly starts the door closing operation as a door closing forced operation.
- the car 1 has a door open button (not shown).
- the door opening button is a button for a passenger to press in the car 1 in order to keep the car door 14 and the landing door 15 open.
- the car door 14 is provided with a reversing device (not shown).
- the reversing device is a device for reversing the operations of the car door 14 and the landing door 15 in which the door closing operation is performed.
- the reversing device is composed of a safety shoe, for example. Even when the door is open in S304, the operation control means 11 does not start the door closing operation when the door opening button is pressed or the reversing device is operated. In such a case, the operation control means 11 notifies the notification device 16 that the door closing operation is forcibly started as the door closing forced operation.
- the door opening button and the reversing device are an example of means for preventing door closing. You may provide another apparatus as a door closing prevention means.
- the operation control means 11 determines whether or not the second level swing of the main rope 3 has been detected by the second detection means 19 (S305).
- the operation control unit 11 stops the operation (S306). In this case, the car 1 continues to stop at the transition stop floor after that. The elevator is returned to normal operation on condition that no abnormality is detected by the inspection of the maintenance staff.
- the operation control means 11 causes the car 1 to travel to the other terminal floor and stop (S307). For example, if the car 1 is stopped at the upper end floor when the first level of swing is detected in S301, the operation control means 11 causes the car 1 to travel to the lower end floor.
- the first detection means 18 starts counting the number of operations of the photoelectric sensors 17-Ax1 and 17-Ay1 again after the car 1 stops at the terminal floor in S307.
- the distance of the main rope 3 where the movement is not restrained constantly changes. For example, when the car 1 travels, the distance from the end portion of the main rope 3 that is connected to the car 1 to the portion that is wound around the drive sheave changes. For this reason, even if the first level swing is detected when the car 1 is stopped at one terminal floor, the swing of the main rope 3 is amplified by moving the car 1 to the other terminal floor. Can be suppressed. That is, in this elevator apparatus, the main rope 3 is prevented from resonating with the shaking of the building and increasing its amplitude by running the car 1.
- the operation control means 11 determines whether a call is registered (S308). If the call is registered, the operation control means 11 performs an operation necessary for responding to the call (S309). Specifically, if a call is registered in S308, the operation control means 11 starts the door opening operation to respond to the call. At this time, the operation control means 11 notifies the notification device 16 that the stop time is limited. For example, the operation control means 11 notifies the notification device 16 that there is a possibility that the door closing operation may be forcibly performed.
- the operation control means 11 determines whether or not a condition for closing the door is satisfied (S310).
- the door closing condition for determining whether or not it is established in S310 is the same as the condition adopted during normal operation. For example, when the passenger presses a door closing button (not shown) in the car 1, the door closing condition is established.
- the operation control means 11 starts the door closing operation (S311).
- the operation control means 11 returns to the process of S305. That is, if the second level swing is not detected, the operation control unit 11 causes the car 1 to travel to the other terminal floor immediately after the door closing is completed.
- the operation control means 11 determines whether or not the first level swing of the main rope 3 has been detected again by the first detection means 18 (S312). In addition, after the door is opened in S309, the operation control unit 11 determines whether or not the first level of the main rope 3 has been detected again by the first detection unit 18 until the door closing condition is satisfied in S310. (S312).
- the operation control means 11 After the car 1 stops at the terminal floor in S307, if a first level swing is detected in S312, the operation control means 11 returns to S304. That is, if the door is currently open, the operation control means 11 starts the door closing forced operation. As a result, even when the car 1 is opened at the landing 12 in response to a call, if a first level swing is detected when the car 1 is stopped at the landing 12, the forced door A notification that a closing operation or a forced door closing operation is performed is performed. Thereafter, if the traveling of the car 1 is started immediately after the door closing is completed, the swing of the main rope 3 can be prevented from being amplified.
- the notification device 16 notifies that the door closing operation may be forcibly performed. Passengers can continue to use the elevator after recognizing that there is a limit on boarding time.
- the operation control means 11 determines whether or not a certain time has elapsed since the car 1 stopped at the terminal floor in S307 (S313). If the door is opened in S309 in response to the call, it may be determined in S313 whether a certain time has passed since the door was opened. The certain time is set to about 3 minutes, for example. If the predetermined time has not elapsed in S313, the operation control unit 11 returns to the process of S312.
- the operation control means 11 starts a forced closing operation if the door is currently open (S314). For example, after the door is opened in S309, when the car 1 continues to stop at the landing 12 for a certain period of time without the first level of swinging being detected, the operation control means 11 starts the door closing forced operation.
- Operation control means 11 will judge whether the present stop floor is a stop floor at the time of transition, if door closing is detected after a fixed time passes in S313 (S315). If the current stop floor is not the transition stop floor (No in S315), the operation control means 11 returns to the process of S305. Thereafter, the operation control means 11 causes the car 1 to travel to the other terminal floor and stop on the condition that the second-level shake is not detected (S307). The terminal floor at which the car 1 stops at this time is necessarily the stop floor at the time of transition.
- the operation control means 11 determines that the swing of the main rope 3 has been stopped. The operation control means 11 cancels the control operation and returns the elevator to the normal operation (S316).
- This elevator device can minimize damage caused by long-period shaking even in buildings where the resonance floor is not set in advance or in buildings where there is no non-resonance floor.
- the non-resonant floor is a floor where the elevator's long object hardly resonates with the shaking of the building or does not resonate when the car 1 is stopped.
- the operation of the photoelectric sensor 17 (the detection function by the detection device 9) is performed while the car 1 is traveling. ) Is disabled.
- the operation of the photoelectric sensor 17 may be always set to be effective.
- the operation control means 11 determines whether or not the car 1 is stopped when the first level of vibration is detected during normal operation. If the car 1 is stopped, the operation control means 11 shifts the elevator to the control operation. For example, the operation control unit 11 determines whether the car 1 is stopped based on the car position detected by the car position detection unit 10.
- FIG. FIG. 7 is a diagram showing an overall configuration of an elevator apparatus according to Embodiment 2 of the present invention.
- an express zone is set.
- the car 1 basically does not stop in the express zone.
- FIG. 7 shows an example in which a plurality of halls 12 are provided below the express zone and a plurality of halls 12 are provided above the express zone.
- the elevator apparatus described in the first embodiment corresponds to the one in which only one landing 12 is provided above and below the express zone in the present embodiment.
- FIG. 8 is a flowchart for explaining the operation of the control device 8 in the second embodiment of the present invention.
- the operations shown in S401 to S406 in FIG. 8 are the same as the operations shown in S301 to S306 in FIG. Further, the operations shown in S408 to S416 in FIG. 8 are the same as the operations shown in S308 to S316 in FIG.
- the operation control means 11 causes the car 1 to travel so as to pass through the express zone and stops at the landing 12 (S407). ). For example, if the floor where the car 1 is currently stopped is a floor above the express zone, the operation control means 11 starts the car 1 to travel toward a floor below the express zone. At this time, if the call is registered, the operation control means 11 stops the car 1 on the floor below the express zone so that the car 1 responds to the registered call. When the call is not registered, the operation control means 11 stops the car 1 on any floor below the express zone. For example, the operation control means 11 stops the car 1 at the lowest floor.
- the operation control means 11 causes the car 1 to travel toward the stop floor at the time of transition and stops at the time of transition. Stop the car 1 on the floor.
- the car 1 since the car 1 travels so as to pass through the express zone, the natural period of the long object can be greatly changed. It is possible to easily prevent the shaking of the long object from increasing.
- the same effect as the effect disclosed in the first embodiment can be obtained.
- FIG. 9 is a diagram showing an overall configuration of an elevator apparatus according to Embodiment 3 of the present invention.
- FIG. 9 shows an example of an elevator apparatus provided with three or more halls 12.
- An express zone may be set in the elevator apparatus shown in FIG.
- FIG. 10 is a flowchart for explaining the operation of the control device 8 in the third embodiment of the present invention.

- the operations shown in S513 to S517 in FIG. 10 are the same as the operations shown in S312 to S316 in FIG.
- the operation control means 11 determines whether or not the call is registered (S507). If the call is registered, the operation control means 11 causes the car 1 to run and stop so that the car 1 responds to the registered call (S508). On the other hand, if no call is registered, the operation control means 11 causes the car 1 to travel to the terminal floor and stop (S512).
- the operation control means 11 causes the car 1 to travel toward the stop floor at the time of transition and stops at the time of transition. Stop the car 1 on the floor.
- the present invention can be easily applied to a general elevator apparatus having a large number of halls 12.
- the present invention can be applied to an elevator equipped with a device for detecting the shake of a long object.
