FIG. 1 is a configuration diagram of an elevator to which the elevator control device according to the first embodiment is applied.

In the elevator of FIG. 1, the hoistway 1 penetrates each floor of the building. The machine room 2 is provided directly above the hoistway 1. Each of the plurality of landings 3 is provided on each floor of the building. Each of the plurality of landing doors 4 is provided at each entrance / exit of the plurality of landings 3.

The hoisting machine 5 is provided in the machine room 2. The sheave 6 is attached to the rotating shaft of the hoisting machine 5. The deflecting wheel 7 is provided in the machine room 2. The deflecting wheel 7 is adjacent to the hoisting machine 5. The main rope 8 is wound around the sheave 6 and the deflecting wheel 7.

The car 9 is provided inside the hoistway 1. The car 9 is supported on one side of the main rope 8. The car door 10 is provided at the doorway of the car 9. The balance weight 11 is provided inside the hoistway 1. The balance weight 11 is supported on the other side of the main rope 8.

For example, the control device 12 is provided in the machine room 2. For example, the control device 12 includes a control unit 12a and a storage unit 12b.

In the elevator, the control unit 12a of the control device 12 transmits a rotation command to the hoisting machine 5. The hoisting machine 5 rotates based on the rotation command. The main rope 8 moves following the rotation of the hoisting machine 5. The basket 9 and the balanced weight 11 move up and down in opposite directions following the movement of the main rope 8.

When the car 9 is stopped facing the landing 3, the control unit 12a of the control device 12 moves the landing door 4 of the landing 3 in the opening / closing direction in conjunction with the car door 10. The landing door 4 is released from interlocking with the car door 10 immediately before it is fully closed. After that, the landing door 4 tries to fully close by receiving a force from a weight, a spring, etc. (not shown).

At this time, the storage unit 12b of the control device 12 stores information regarding the status of the elevator. For example, the storage unit 12b stores information regarding opening and closing of the landing door 4 and the car door 10.

Next, the car 9 will be described with reference to FIG.
FIG. 2 is a front view of an elevator car to which the elevator control device according to the first embodiment is applied.

As shown in FIG. 2, the car 9 is supported by the car frame 13. For example, the car frame 13 includes a plurality of car position correction devices. Specifically, the car frame 13 includes a one-side upper car position correction device 14a, another side upper car position correction device 14b, one side lower car position correction device 14c, and another side lower car position correction device 14d.

The one-side upper car position correction device 14a is provided so as to be able to be guided in the vertical direction to one of the pair of guide rails 15 on one side of the upper part of the car frame 13. The other side upper car position correction device 14b is provided so as to be able to be guided in the vertical direction to one of the pair of guide rails 15 on the other side of the upper part of the car frame 13. The one-side lower car position correction device 14c is provided so as to be able to be guided in the vertical direction to the other of the pair of guide rails 15 on one side of the lower part of the car frame 13. The other side lower car position correction device 14d is provided so as to be able to be guided in the vertical direction to the other side of the pair of guide rails 15 on the other side of the lower part of the car frame 13.

For example, in a skyscraper, the car 9 travels at high speed. At this time, if the straightness of the guide rail 15 and the installation accuracy are poor, the riding comfort of the car 9 deteriorates. Therefore, the one-side upper car position correction device 14a, the other-side upper car position correction device 14b, the one-side lower car position correction device 14c, and the other-side lower car position correction device 14d detect the acceleration of the horizontal component of the car 9. Based on the result, a guide roller (not shown) is moved by an actuator (not shown). As a result, the position of the car 9 is corrected in the opposite direction to the horizontal shaking. Therefore, the ride quality of the car 9 is improved.

Next, the landing door 4 will be described with reference to FIGS. 3 and 4.

When each of the pair of door panels 4a is in the door closed position, the actuating piece 4e is pushed by one of the protruding portions 4f of the pair of door panels. As a result, the contacts of the switch body 4d are closed. At this time, the switch body 4d transmits a fully closed signal of the landing door 4.

When each of the pair of door panels 4a moves from the door closed position to the door open direction, the actuating piece 4e rotates. As a result, the contacts of the switch body 4d are opened. At this time, the switch body 4d does not transmit the fully closed signal of the landing door 4.

Next, the car door 10 will be described with reference to FIGS. 5 and 6.
5 and 6 are front views of the elevator car door to which the elevator control device according to the first embodiment is applied.

As shown in FIGS. 5 and 6, the car door 10 includes a pair of door panels 10a. The pair of blades 10b is provided on one of the pair of door panels 10a. The pair of blades 10b face each other in the frontage direction of the entrance / exit of the car 9. The pair of blades 10b are arranged so that the landing door 4 is interlocked with the car door 10 when the car 9 enters the door openable / closable section. Specifically, the pair of blades 10b are provided so as to be arranged on both sides of the roller 4b of the landing door 4.

Each of the pair of car door switches 10c includes a switch body 10d and an actuating piece 10e.

When each of the pair of door panels 10a is in the door closed position, the corresponding actuating piece 10e is pushed by the door hanger 10f of the corresponding door panel 10a. As a result, the contact of the corresponding switch body 10d is closed. At this time, the switch body 10d transmits a fully closed signal of the car door 10.

When each of the pair of door panels 10a moves from the door closed position to the door opening direction, the corresponding actuating piece 10e rotates. As a result, the contact of the corresponding switch body 10d opens. At this time, the switch body 10d does not transmit the fully closed signal of the car door 10.

Next, with reference to FIG. 7, the outline of the operation when the control device 12 fully closes the landing door 4 will be described.
FIG. 7 is a flowchart for explaining an outline of the operation when the elevator control device in the first embodiment fully closes the landing door.

In step S1, the control unit 12a determines whether or not the car 9 is stopped facing the landing 3. If the car 9 is not stopped facing the landing 3 in step S1, the control unit 12a performs the operation of step S1. When the car 9 is stopped facing the landing 3 in step S1, the control device 12 operates in step S2.

In step S2, the control unit 12a determines whether or not the fully closed signal of the car door 10 has been received. If the fully closed signal of the car door 10 is not received in step S2, the control unit 12a operates in step S2. When the fully closed signal of the car door 10 is received in step S2, the control device 12 operates in step S3.

In step S3, the control unit 12a determines whether or not the fully closed signal of the landing door 4 has been received.

When the fully closed signal of the landing door 4 is received in step S3, the control unit 12a ends the operation.

If the fully closed signal of the landing door 4 is not received in step S3, the control unit 12a operates in step S4.

In step S4, the control unit 12a determines whether or not a certain time has elapsed after receiving the fully closed signal of the car door 10. For example, the control unit 12a determines whether or not 0.5 seconds have elapsed after receiving the fully closed signal of the car door 10.

If a certain period of time has not elapsed since the fully closed signal of the car door 10 was received in step S4, the control unit 12a performs the operation of step S3.

When a certain time has elapsed after receiving the fully closed signal of the car door 10 in step S4, the control unit 12a performs the operation of step S5.

In step S5, the control unit 12a operates the car position correction device so that the car 9 moves in the direction in which the landing door 4 is fully closed. After that, the control device 12 performs the operation of step S6.

In step S6, the control unit 12a determines whether or not the fully closed signal of the landing door 4 has been received.

When the fully closed signal of the landing door 4 is received in step S6, the control unit 12a ends the operation.

If the fully closed signal of the landing door 4 is not received in step S6, the control unit 12a operates in step S7.

In step S7, the control unit 12a determines whether or not a certain time has elapsed since the car position correction device was operated so that the car 9 moves in the direction in which the landing door 4 is fully closed. For example, the control unit 12a determines whether or not 1.0 second has elapsed since the car position correction device was operated so that the car 9 moves in the direction in which the landing door 4 is fully closed.

If a certain time has not passed since the car position correction device was operated so that the car 9 moves in the direction in which the landing door 4 is fully closed in step S7, the control unit 12a performs the operation of step S6.

When a certain time has elapsed since the car position correction device was operated so that the car 9 moves in the direction in which the landing door 4 is fully closed in step S7, the control unit 12a operates the step S8.

In step S8, the control unit 12a closes the car door 10 after opening the car door 10. After that, the control unit 12a performs the operation of step S2.

According to the first embodiment described above, the control device 12 operates the car position correction device so that the car 9 moves in the direction in which the landing door 4 is fully closed while the car 9 is stopped. Therefore, the landing door 4 can be reliably fully closed on each of the plurality of floors without adding a new device. As a result, it is possible to reduce the trouble that the car 9 cannot run in a strong wind.

At this time, it is not necessary to increase the force when the landing door 4 is fully closed. Therefore, the landing door 4 can be reliably fully closed without increasing the collision noise when the landing door 4 is fully closed. Further, the landing door 4 can be reliably fully closed without increasing the impact when the landing door 4 hits the user.

Further, when the control device 12 does not receive the fully closed signal of the landing door 4 within a certain period of time after receiving the fully closed signal of the car door 10, the car 9 is in the direction of fully closing the landing door 4. Operate the car position correction device so that the door moves. Therefore, the car position correction device can be operated only when necessary. Therefore, the operating efficiency of the elevator can be improved.

Further, when the control device 12 does not receive the fully closed signal of the landing door 4 until a certain time elapses after operating the car position correction device so that the car 9 moves in the direction in which the landing door 4 is fully closed. After opening the car door 10, the car door 10 is closed. Therefore, when the landing door 4 is not fully closed even if the car position correction device is operated, it is possible to try to fully close the landing door 4 again.

In the storage unit 12b of the control device 12, information is provided between the time when the car position correction device is operated so that the car 9 moves in the direction in which the landing door 4 is fully closed and the floor on which the landing 3 is provided. You may remember it. In this case, at the time of maintenance of the elevator, the information of the landing door 4 to be maintained can be appropriately presented to the worker.

Further, on the floor where the car position correction device is operated so that the car 9 moves in the direction in which the landing door 4 is fully closed, the brake of the hoisting machine 5 is released to shorten the inter-floor movement time of the car 9. You may cancel the pre-release function. In this case, safety can be ensured on the floor where the landing door 4 is difficult to fully close.

Further, on the floor where the car position correction device is operated a plurality of times, the pre-release function may be canceled for another car 9 in the same bank as the car 9. In this case, safety can be ensured on the floor where the landing door 4 is difficult to fully close.

Further, when each of the plurality of landing door switches 4c is provided for each of the pair of door panels 4a of the landing door 4, the car position correction device is provided according to the operating status of each of the plurality of landing door switches 4c. May be operated. For example, when the fully closed signal of one of the pair of door panels 4a is not received but the other fully closed signal of the pair of door panels 4a is received until a certain time elapses after receiving the fully closed signal of the car door 10. The car position correction device may be operated so that the car 9 moves in the direction in which one of the pair of door panels 4a is fully closed. For example, if the fully closed signals of both of the pair of door panels 4a are not received within a certain period of time after receiving the fully closed signal of the car door 10, one of the pair of door panels 4a is fully closed and the pair is paired. The car position correction device may be operated so that the car moves alternately in the direction in which the other side of the door panel 4a is fully closed. In this case as well, the landing door 4 can be reliably fully closed.

Further, the control device 12 of the first embodiment may be applied to an elevator without a machine room 2. In this case as well, the landing door 4 can be reliably fully closed.

Further, the upper car position correction device 14a on one side and the upper car position correction device 14b on the other side may not be provided. In this case, by operating the lower car position correction device 14c on one side and the lower car position correction device 14d on the other side, the landing door 4 can be reliably fully closed.
