Problems to be solved by the invention
In the elevator apparatus described in patent document 1, a plurality of members forming the gap are photographed by a camera. Since a part of the member forming the gap is shot obliquely by the camera, the depth of the member shot by the camera must be taken into consideration in order to accurately measure the gap. Therefore, there is a problem that complicated processing is required.
The present invention has been made to solve the above problems. The invention aims to provide an elevator device which can simply and accurately measure the clearance required by a device for locking a landing door.
Means for solving the problems
An elevator device of the present invention includes: a car having a car door and a sensor provided at the car door; a landing door provided at a landing where the car stops; a lock member provided in the landing door and having an opposing portion; a receiving member having a receiving portion; and a calculation unit that calculates a distance between the facing portion and the receiving portion based on a result of detection by the sensor. The lock member is configured to be capable of being disposed at a lock position where the facing portion contacts the receiving portion when the landing door moves in the opening direction and at an unlock position where the facing portion does not contact the receiving portion even when the landing door moves in the opening direction. When the car door passes the 1 st position in the opening direction when the car is stopped at a landing, the lock member starts moving from the lock position to the unlock position. When the car door passes the 2 nd position in the opening direction when the car stops at the landing, the landing door starts moving in the opening direction. The 2 nd position is a position farther from the fully-closed position than the 1 st position. When the car door is disposed at the fully closed position when the car is stopped at the landing, the opposing portion becomes a detection target of the sensor. When the car door moves from the fully closed position in the opening direction when the car stops at the landing, the opposing portion is excluded from the detection target of the sensor before the car door reaches the 1 st position, and then the receiving portion becomes the detection target of the sensor.
Effects of the invention
The elevator device of the invention can simply and accurately measure the clearance required by a device for locking a landing door.

Detailed Description
The invention is described with reference to the accompanying drawings. The repeated explanation is appropriately simplified or omitted. In the drawings, the same reference numerals denote the same or equivalent parts.
Fig. 1 is a diagram showing an example of an elevator apparatus according to embodiment 1 of the present invention. The elevator apparatus includes, for example, a car 1 and a counterweight 2. The car 1 moves up and down in the hoistway 3. The counterweight 2 moves up and down in the hoistway 3. The car 1 and the counterweight 2 are suspended from a hoistway 3 by main ropes 4. The roping method for suspending the car 1 and the counterweight 2 is not limited to the example shown in fig. 1.
The main ropes 4 are wound around a drive sheave 6 of the hoisting machine 5. The rotation and stop of the drive sheave 6 are controlled by a control device 7. The control device 7 is connected to the car 1 via a control cable 8. The devices provided in the car 1 are controlled by the control device 7. When the drive sheave 6 rotates, the main ropes 4 move in a direction corresponding to the rotation direction of the drive sheave 6. The car 1 ascends or descends according to the direction in which the main rope 4 moves. The hoisting machine 5 is a device for driving the car 1. The control device 7 stops the car 1 in accordance with the height of the landing 9, for example.
Fig. 1 shows an example in which a hoisting machine 5 and a control device 7 are installed in a machine room. The hoisting machine 5 and the control device 7 may be installed in the hoistway 3.
The car 1 is provided with a car door device. Landing door devices are provided at each landing 9. Hereinafter, a car door device and a landing door device will be described in detail with reference to fig. 2 to 12. Fig. 2 is an enlarged view of a portion a shown in fig. 1. Fig. 3 is a diagram showing an example of a landing door device viewed from the car 1 side. Fig. 2 and 3 show a state in which the car 1 is stopped at a certain landing 9. In fig. 3, a part of the car door apparatus is also illustrated.
The landing door device includes, for example, a landing door 10, a hanger case 11, a door rail 12, a lock device 13, and a roller 14.
The landing door 10 opens and closes an entrance formed in the landing 9. Hereinafter, the doorway formed in the landing 9 will be referred to as a landing doorway. Fig. 2 and the like show an example in which the landing door 10 includes a door panel 15, a door hanger 16, and a door roller 17. The landing doorway is closed by a door panel 15. The door hanger 16 is provided on the upper portion of the door panel 15 so as to extend upward from the door panel 15. The door roller 17 is rotatably provided in the door hanger 16.
The hanger case 11 is provided, for example, in a fixed body of the hoistway 3. The hanger case 11 is disposed above the landing doorway. The door rail 12 is supported by the hanger case 11. The door rail 12 is disposed above the landing doorway. The door rail 12 is disposed horizontally in the front width direction of the landing doorway. The door roller 17 is placed on the upper surface of the door rail 12. Thereby, the landing door 10 is suspended from the door rail 12. The door roller 17 rolls on the upper surface of the door rail 12, thereby guiding the movement of the landing door 10.
The landing door 10 is locked by a lock device 13. The lock device 13 includes, for example, a receiving member 18, a lock member 19, a shaft 20, an arm 21, and a roller 22.
The receiving member 18 includes a receiving portion 23. In the example shown in fig. 3, the receiving portion 23 is a portion of the receiving member 18 that protrudes upward. The receiving member 18 is provided on the surface 24a of the mounting member 24. The surface 24a faces the hoistway 3 side. The mounting member 24 is provided to the hanger case 11. The mounting member 24 is disposed adjacent to the landing door 10. For example, mounting member 24 is adjacent door hanger 16.
The lock member 19 is provided to the landing door 10 via a shaft 20. In the example shown in fig. 3, the lock member 19 is provided to the door hanger 16. The lock member 19 is displaced about the shaft 20. For example, the lock member 19 can be arranged in a lock position and an unlock position. The locked position is a position for locking the landing door 10. Figure 3 shows an example of a configuration of the lock member 19 in the locked position. The lock member 19 has an opposing portion 25. In the example shown in fig. 3, the opposing portion 25 is a portion of the lock member 19 that protrudes downward. When the lock member 19 is disposed at the lock position, the facing portion 25 faces the receiving portion 23 of the receiving member 18. When the landing door 10 moves from the fully closed position to the open direction in a state where the lock member 19 is disposed at the lock position, the opposing portion 25 contacts the receiving portion 23. Thereby, the landing door 10 is prevented from opening.
The unlocked position is a position for allowing the landing door 10 to be opened and closed. When the lock member 19 is disposed at the unlocked position, the opposing portion 25 does not contact the receiving portion 23 even if the landing door 10 moves in the opening direction. The lock member 19 is constantly urged by a member (not shown) such as a spring to be disposed at the lock position. Therefore, if no external force is applied to the lock device 13, the lock member 19 is disposed at the lock position.
The lower end of the arm 21 is provided to the shaft 20. The arm 21 extends upward from the shaft 20. For example, if no external force is applied to the lock device 13, the upper end of the arm 21 is disposed on the left side of the shaft 20 in fig. 3. The roller 22 is rotatably provided at an upper end portion of the arm 21.
The roller 14 is rotatably provided in the landing door 10. Fig. 2 and 3 show an example in which the roller 14 is provided to the landing door 10 via a shaft 20. For example, the diameter of roller 14 is the same as the diameter of roller 22. The roller 22 is disposed on the left side of the roller 14 in fig. 3 if no external force acts on the lock device 13. When the car 1 stops at the landing 9, the rollers 22 and 14 are disposed closer to the car 1 than the landing door 10.
The car door apparatus includes, for example, a car door 26, a hanger case 27, a door rail 28, a motor 29, a plate 30, a plate 31, and a sensor 32.
The car door 26 opens and closes an entrance formed in the car 1. Hereinafter, the doorway formed in the car 1 will be referred to as a car doorway. Fig. 2 shows an example in which the car door 26 includes a door panel 33, a door hanger 34, and a door roller 35. The car doorway is closed by a door panel 33. The door hanger 34 is provided on the upper portion of the door panel 33 so as to extend upward from the door panel 33. The door roller 35 is rotatably provided in the door hanger 34.
The hanger case 27 is provided to a member forming a car room, for example. The hanger case 27 is disposed above the car doorway. The door rail 28 is supported by the hanger case 27. The door rail 28 is disposed above the car doorway. The door rail 28 is disposed horizontally in the front width direction of the car doorway. The door roller 35 is placed on the upper surface of the door rail 28. Thereby, the car door 26 is suspended from the door rail 28. The door rollers 35 roll on the upper surfaces of the door rails 28, thereby guiding the movement of the car doors 26.
The motor 29 is supported by the hanger case 27, for example. The motor 29 generates a driving force for opening and closing the car doors 26. The driving force of the motor 29 is transmitted to the car door 26 via a switching device (not shown). The motor 29 is controlled by the control device 7.
The plates 30 and 31 are provided to the car door 26. The plates 30 and 31 are arranged in parallel to face each other at a predetermined interval. The plate 30 is disposed longitudinally with a surface 30a opposed to the plate 31 facing the opening direction of the car doors 26. The plate 31 is disposed longitudinally with a surface 31a opposed to the plate 30 facing the closing direction of the car doors 26. When the car 1 stops at the landing 9, the plates 30 and 31 are disposed closer to the landing 9 than the car door 26. Further, if the car 1 stops at the landing 9, the rollers 14 and 22 are disposed between the plates 30 and 31.
The sensor 32 is provided to the car door 26. Fig. 2 shows an example in which the sensor 32 is provided to the door hanger 34. The sensor 32 is, for example, a distance sensor. The sensor 32 outputs the detection light horizontally toward the landing 9 side, for example, and receives the reflected light thereof. For example, the detection light from the sensor 32 is emitted in a direction perpendicular to the opening and closing directions of the car doors 26. The sensor 32 detects the distance to the object irradiated with the detection light based on the received reflected light. The result detected by the sensor 32 is output to the control device 7.
Next, the operation of the car 1 when it is stopped at the landing 9 will be described with reference to fig. 4 to 8. Fig. 4 to 8 are diagrams for explaining the functions of the landing door apparatus and the car door apparatus.
Fig. 4 shows a state immediately after the car 1 stops at the landing 9. Immediately after the car 1 stops at the landing 9, the landing door 10 is disposed at the fully closed position. Immediately after the car 1 stops at the landing 9, the lock member 19 is arranged at the lock position. Therefore, the opposed portion 25 of the lock member 19 is opposed to the receiving portion 23 of the receiving member 18. When the lock member 19 is disposed at the lock position, a gap having a width w1 is formed between the facing portion 25 and the receiving portion 23.
Immediately after the car 1 stops at the landing 9, the car door 26 is disposed at the fully closed position. Immediately after the car 1 stops at the landing 9, the rollers 14 and 22 are disposed between the plates 30 and 31. At this time, the rollers 14 and 22 do not contact the plates 30 and 31. If the car door 26 is disposed at the fully closed position, a gap of width w2 is formed between the plate 30 and the roller 22. If the car door 26 is disposed at the fully closed position, a gap of width w3 is formed between the plate 30 and the roller 14. Width w3 is greater than width w 2. X0 shown in fig. 4 to 8 indicates the position of the surface 30a of the panel 30 with respect to the moving direction of the car doors 26 when the car doors 26 are disposed at the fully closed position. The position x0 corresponds to the fully closed position of the car door 26.
When the car 1 stops at the landing 9, the car door 26 is moved in the opening direction by the motor 29. The plates 30 and 31 are provided to the car door 26. Therefore, when the car door 26 moves in the opening direction, the plates 30 and 31 also move in the opening direction. In the example shown in fig. 4, the plate 30 moves in such a manner as to approach the roller 22.
If the plate 30 moves a distance of width w2, the plate 30 contacts the roller 22. X1 shown in fig. 4 to 8 indicates the position of the end of the roller 22 with respect to the movement direction of the landing door 10 when the landing door 10 is disposed at the fully closed position. The end is the closest portion of the roller 22 to the plate 30. The position x1 corresponds to the 1 st position of the car door 26.
Fig. 5 shows a state in which the plate 30 has just contacted the roller 22, that is, a state in which the car door 26 reaches the 1 st position. In the example shown in the present embodiment, the position at which the surface 30a of the panel 30 reaches the position x1 is the 1 st position of the car door 26. When the car door 26 moves further in the opening direction from the 1 st position, the roller 22 is pressed by the plate 30. Thereby, the shaft 20 rotates to move the roller 22 in the opening direction of the car door 26. The lock member 19 is fixed to the shaft 20. Therefore, when the shaft 20 rotates, the lock member 19 rotates to move the opposing portion 25 upward. When the car door 26 reaches the 1 st position from the fully closed position, the lock member 19 starts moving from the locked position to the unlocked position. That is, when the car door 26 moves beyond the 1 st position in the opening direction, the lock member 19 starts moving from the lock position to the unlock position.
Fig. 6 shows a state in which the car door 26 is moved further in the opening direction from the state shown in fig. 5, and the lock member 19 is disengaged from the receiving member 18. In the state shown in fig. 6, the landing door 10 is still disposed at the fully closed position.
If the plate 30 moves a distance of width w3, the plate 30 contacts the roller 14. X2 shown in fig. 4 to 8 indicates the position of the end of the roller 14 with respect to the movement direction of the landing door 10 when the landing door 10 is disposed at the fully closed position. The end is the closest portion of the roller 14 to the plate 30. The position x2 corresponds to the 2 nd position of the car door 26. The 2 nd position is a position farther from the fully-closed position than the 1 st position.
Fig. 7 shows a state immediately after the plate 30 comes into contact with the roller 14, that is, a state in which the car door 26 reaches the 2 nd position. In the example shown in the present embodiment, the position at which the surface 30a of the panel 30 reaches the position x2 is the 2 nd position of the car door 26. In the state shown in fig. 7, the lock member 19 is arranged at the unlock position. When the car door 26 moves further in the opening direction from the 2 nd position, the roller 14 is pressed by the plate 30. The roller 14 is provided on a shaft 20 fixed to the landing door 10. Therefore, when the plate 30 comes into contact with the roller 14, the landing door 10 moves in the opening direction together with the car door 26. When the car door 26 passes the 1 st position from the fully closed position to reach the 2 nd position, the landing door 10 starts moving in the opening direction. That is, when the car door 26 passes the 2 nd position in the opening direction, the landing door 10 starts moving in the opening direction. Fig. 8 shows a state in which the car door 26 is moved further in the opening direction from the state shown in fig. 7. In the example shown in the present embodiment, the roller 14, the plate 30, and the plate 31 constitute a device for interlocking the landing door 10 and the car door 26.
Next, a detection target of the sensor 32 will be described in detail. Fig. 9 to 12 are diagrams for explaining the function of the sensor 32. Fig. 9 shows a state immediately after the plate 30 comes into contact with the roller 22, that is, a state in which the car door 26 reaches the 1 st position. In fig. 9, the position of the plate 30 immediately after the car 1 stops at the landing 9 is indicated by a two-dot chain line. As described above, immediately after the car 1 stops at the landing 9, the car door 26 is disposed at the fully closed position. Immediately after the car 1 stops at the landing 9, the landing door 10 is disposed at the fully closed position. Immediately after the car 1 stops at the landing 9, the lock member 19 is arranged at the lock position.
A point B shown in fig. 9 indicates a position to which the detection light emitted from the sensor 32 is irradiated immediately after the car 1 stops at the landing 9. As shown in fig. 9, when the car 1 stops at the landing 9, if the car door 26 is disposed at the fully closed position, the opposing portion 25 becomes a detection target of the sensor 32. That is, the detection light emitted from the sensor 32 is irradiated to the opposite unit 25. Thereby, the distance to the facing portion 25 is detected by the sensor 32. Fig. 10 to 12 are views corresponding to the D-D section of fig. 9. Fig. 10 shows a cross section when the car door 26 is disposed at the fully closed position.
As described above, the sensor 32 is provided to the car door 26. Therefore, when the car door 26 moves in the opening direction, the sensor 32 also moves in the opening direction. When the car door 26 moves from the fully closed position to the 1 st position, the position at which the detection light emitted from the sensor 32 is irradiated to the object changes as indicated by arrow C in fig. 9. As shown in fig. 9, before the car door 26 reaches the 1 st position, the opposing portion 25 is excluded from the detection objects of the sensor 32. Fig. 11 shows a cross section when the opposing portion 25 is excluded from the detection object of the sensor 32. At this time, the detection light emitted from the sensor 32 passes through the space between the opposing portion 25 and the receiving portion 23 and is irradiated to the surface 24a of the mounting member 24. That is, the detection target of the sensor 32 is changed from the facing portion 25 to the mounting member 24. Thereby, the distance to the mounting member 24 is detected by the sensor 32.
When the car door 26 moves further in the opening direction from the state shown in fig. 11, the receiving portion 23 becomes the detection target of the sensor 32 before the car door 26 reaches the 1 st position. That is, the detection light emitted from the sensor 32 is irradiated to the receiving unit 23. Thereby, the distance to the receiving unit 23 is detected by the sensor 32. Fig. 12 shows a cross section of the car door 26 when it reaches the 1 st position. As described above, when the car door 26 moves beyond the 1 st position in the opening direction, the lock member 19 starts moving from the lock position to the unlock position. The lock member 19 does not start moving until the car door 26 reaches the 1 st position.
Fig. 13 is a diagram showing an example of the control device 7. The control device 7 includes, for example, a storage unit 36, a calculation unit 37, a determination unit 38, and an operation control unit 39. The storage unit 36 stores a reference range in advance. This reference range is used to determine whether or not an abnormality occurs in the lock device 13.
Hereinafter, an operation for measuring the distance between the receiving portion 23 of the receiving member 18 and the opposing portion 25 of the lock member 19 will be described with reference to fig. 14. Fig. 14 is a flowchart showing an operation example of an elevator apparatus according to embodiment 1 of the present invention. Fig. 14 shows an example of the measurement of the above distance by the diagnostic operation.
The control device 7 determines whether or not a start condition of the diagnostic operation is satisfied (S101). The diagnostic operation is performed, for example, periodically. For example, if a specific date and time is reached and no person is riding in the car 1, the control device 7 determines that the start condition of the diagnostic operation is satisfied. Other conditions may also be employed as starting conditions for the diagnostic operation. The start condition is stored in the storage unit 36 in advance. If the start condition is satisfied, the control device 7 starts the diagnostic operation (S102). The diagnostic operation is controlled by, for example, the operation control unit 39.
The operation control section 39 first stops the car 1 at the landing 9 (S103). When the car 1 stops at the landing 9, the detection of the distance by the sensor 32 is started (S104). Immediately after the detection by the sensor 32 is started, the car door 26 is disposed at the fully closed position. Therefore, the detection light from the sensor 32 is irradiated to the opposite part 25. The distance to the facing portion 25 is detected by the sensor 32.
When the detection is started by the sensor 32, the operation controller 39 moves the car doors 26 in the opening direction (S105). As described above, even if the opening action of the car door 26 is started, the lock device 13 does not move until the car door 26 reaches the 1 st position. The lock member 19 remains arranged in the locked position. Before the car door 26 reaches the 1 st position, the detection target of the sensor 32 changes from the facing portion 25 to the mounting member 24, and further changes from the mounting member 24 to the receiving portion 23.
The distance detection by the sensor 32 is performed at least until the receiving unit 23 becomes a detection target of the sensor 32. For example, when the car door 26 reaches the 1 st position, the distance detection based on the sensor 32 ends (S106). The distance detection based on the sensor 32 can also be ended when the car door 26 reaches the 2 nd position. The distance detection based on the sensor 32 can also be ended after the car door 26 passes the 2 nd position. As another example, the distance detection by the sensor 32 may be ended based on the elapsed time from the start of the opening operation of the car door 26.
The calculation unit 37 calculates the distance between the receiving unit 23 of the receiving member 18 and the facing unit 25 of the lock member 19 based on the result detected by the sensor 32 (S107). Fig. 15 is a diagram showing an example of the result detected by the sensor 32. In fig. 15, time t0 is the time when the opening operation of the car door 26 starts. The time t3 is the time when the car door 26 reaches the 1 st position. Fig. 15 shows a case where the facing portion 25 is excluded from the detection target of the sensor 32 at time t 1. Similarly, at time t2, the receiving unit 23 is the detection target of the sensor 32. The speed of movement of the car door 26 is known. The calculation unit 37 can determine the distance between the receiving unit 23 and the facing unit 25 based on the time required from the time when the facing unit 25 is excluded from the detection target of the sensor 32 to the time when the receiving unit 23 becomes the detection target of the sensor 32.
The determination unit 38 determines whether or not the distance calculated by the calculation unit 37 enters the reference range stored in the storage unit 36 (S108). If the distance calculated by the calculation unit 37 does not fall within the reference range, the determination unit 38 detects that an abnormality has occurred in the lock device 13 (S109). For example, if the opposing portion 25 and the receiving portion 23 are too close to each other, the opposing portion 25 hooks the receiving portion 23 when the lock member 19 is displaced from the lock position to the unlock position. In this case, the landing door 10 and the car door 26 cannot be opened. If a person gets on the car 1, the person is confined to the car.
The operation control unit 39 may perform a predetermined operation when the determination unit 38 detects an abnormality. For example, when the determining unit 38 detects an abnormality, the operation control unit 39 displays information that an abnormality is detected on a display (not shown) provided in the car 1. The operation control unit 39 may report the detection of the abnormality to the outside when the determination unit 38 detects the abnormality. The operation control unit 39 may store information indicating that an abnormality is detected in the storage unit 36 when the determination unit 38 detects an abnormality.
The lock device 13 provided in each landing 9 is subjected to the processing shown in S103 to S109. After the processing shown in S103 to S109 is performed on the lock devices 13 installed in a certain landing 9, it is determined whether or not the distance measurement has been performed on all the lock devices 13 (S110). If there is a lock device 13 for which distance measurement is not performed, the car 1 is stopped at the landing 9 having the lock device 13.
In the example shown in the present embodiment, the clearance required for the lock device 13, that is, the distance between the receiving portion 23 and the opposing portion 25 can be measured easily and accurately.
In the present embodiment, an example in which the sensor 32 is a distance sensor is explained. This is an example. For example, a sensor that is less expensive than a distance sensor may be used as the sensor 32. As the sensor 32, a sensor that cannot detect the distance to the object but can detect the presence or absence of the object under a certain condition may be used. For example, the sensor 32 outputs detection light, and detects the presence or absence of an object from its reflected light.
For example, if the car door 26 is disposed at the fully closed position when the car 1 stops at the landing 9, the detection light emitted from the sensor 32 is irradiated to the opposing portion 25. When the car door 26 moves from the fully closed position in the opening direction, the opposing portion 25 is excluded from the detection objects of the sensor 32 before the car door 26 reaches the 1 st position. When the car door 26 moves from the fully closed position in the opening direction, the receiving portion 23 becomes a detection target of the sensor 32 after the opposing portion 25 is excluded from the detection target of the sensor 32 and before the car door 26 reaches the 1 st position. That is, the detection light emitted from the sensor 32 is irradiated to the receiving unit 23. The calculation unit 37 can calculate the distance between the receiving unit 23 and the facing unit 25 based on the result detected by the sensor 32.
In addition, as in the example shown in the present embodiment, when a part of the mounting member 24 is disposed between the facing portion 25 and the receiving portion 23 when viewed from the sensor 32 side, the mounting member 24 becomes a detection target of the sensor 32 after the facing portion 25 is excluded from the detection target of the sensor 32. In this case, the mounting member 24 may be subjected to a process for suppressing reflection of the detection light from the sensor 32 at a portion to which the detection light is irradiated. For example, the portion is subjected to reflection-free processing. The non-reflection treatment includes coating for realizing non-reflection, sticking a non-reflection sheet, and the like.
In the present embodiment, an example in which the determination unit 38 performs only the determination shown in S108 is described. This is an example. For example, the determination unit 38 may determine whether the stop position of the car 1 is shifted based on the result detected by the sensor 32. Such a determination is performed after the determination shown in S108 is performed, for example.
Fig. 16 is a view of the lock device 13 viewed from the car 1 side. Fig. 16 is a view corresponding to fig. 9. For example, when the stop position of the car 1 is shifted upward when the car 1 stops at the landing 9, the detection light emitted from the sensor 32 is irradiated to the position of the point B1 shown in fig. 16. When the car door 26 moves in the opening direction from the state where the detection light is irradiated to the point B1, the position where the detection light emitted from the sensor 32 is irradiated to the object changes as indicated by an arrow C1 in fig. 16. At this time, the receiving unit 23 is not a detection target of the sensor 32. Fig. 17 is a diagram showing an example of the result detected by the sensor 32. Fig. 17 shows the result when the position where the detection light is irradiated to the object is changed as shown by arrow C1. The determination unit 38 may determine that the stop position of the car 1 is shifted upward when the facing portion 25 is a detection target of the sensor 32 and the receiving portion 23 is not a detection target of the sensor 32, for example.
As another example, when the stop position of the car 1 is shifted downward when the car 1 stops at the landing 9, the detection light emitted from the sensor 32 is irradiated to the position of the point B2 shown in fig. 16. That is, the detection light emitted from the sensor 32 is irradiated to the mounting member 24. When the car door 26 moves in the opening direction from the state where the detection light is irradiated to the point B2, the position where the detection light emitted from the sensor 32 is irradiated to the object changes as indicated by an arrow C2 in fig. 16. At this time, the opposing portion 25 is not a detection target of the sensor 32, and the receiving portion 23 is a detection target of the sensor 32 before the car door 26 reaches the 1 st position. Fig. 18 is a diagram showing an example of the result detected by the sensor 32. Fig. 18 shows the result when the position where the detection light is irradiated to the object is changed as shown by arrow C2. The determination unit 38 may determine that the stop position of the car 1 is shifted downward when the facing portion 25 is not always the detection target of the sensor 32 and the receiving portion 23 is the detection target of the sensor 32, for example.
In the present embodiment, an example in which the receiving portion 23 is a detection target of the sensor 32 before the car door 26 reaches the 1 st position is described. This is an example. The timing at which the receiving portion 23 becomes the detection target of the sensor 32 may be after the car door 26 reaches the 1 st position. As described above, when the car door 26 reaches the 1 st position from the fully closed position, the lock member 19 starts moving to the unlock position. However, even if the car door 26 reaches the 1 st position, the receiver member 18 does not move. Therefore, as in the example shown in the present embodiment, even if the lock member 19 starts moving, the receiving portion 23 does not become the detection target of the sensor 32 after the car door 26 reaches the 1 st position as long as the detection light is not blocked by the lock member 19.
As another example, the distance between the receiving portion 23 and the opposing portion 25 may be measured without opening the landing door 10. In this case, when the car door 26 moves in the opening direction when the car 1 stops at the landing 9, the receiving portion 23 must be a detection target of the sensor 32 at least before the car door 26 reaches the 2 nd position. For example, the operation control unit 39 may be configured to open the car doors 26 in S105 and then move the car doors 26 in the closing direction before the car doors 26 reach the 2 nd position. Thus, the distance between the receiving portion 23 and the opposing portion 25 can be obtained without moving the landing door 10.
The parts indicated by reference numerals 36 to 39 represent functions of the control device 7. Fig. 19 is a diagram showing a hardware configuration of the control device 7. The control device 7 includes, as hardware resources, processing circuits including, for example, a processor 40 and a memory 41. The memory 41 realizes the functions of the storage unit 36. The control device 7 realizes the functions of the respective sections shown by reference numerals 37 to 39 by executing a program stored in the memory 41 by the processor 40. Part or all of the functions of the control device 7 may be implemented by hardware.
