The control device 7 stops the car 1 according to the height of the hall 9, for example.

FIG. 1 shows an example in which a hoisting machine 5 and a control device 7 are provided in a machine room. The hoisting machine 5 and the control device 7 may be provided in the hoistway 3.

Car 1 includes a car door device. Each hall 9 is provided with a hall door device. Hereinafter, the car door device and the landing door device will be described in detail with reference to FIGS. FIG. 2 is an enlarged view of portion A shown in FIG. FIG. 3 is a diagram illustrating an example of the landing door device viewed from the car 1 side. 2 and 3 show a state where the car 1 is stopped at the landing 9 where the car 1 is located. FIG. 3 also shows a part of the car door device.

The landing door device includes a landing door 10, a hanger case 11, a door rail 12, a lock device 13, and a roller 14, for example.

The landing door 10 opens and closes the entrance / exit formed in the landing 9. Hereinafter, the entrance / exit formed in the landing 9 is referred to as a landing entrance / exit. 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 entrance is closed by the 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 on the door hanger 16.

The hanger case 11 is provided on a fixed body of the hoistway 3, for example. The hanger case 11 is disposed above the hall entrance / exit. The door rail 12 is supported by the hanger case 11. The door rail 12 is disposed above the landing entrance. Moreover, the door rail 12 is horizontally arranged in the entrance direction of the hall entrance. The door roller 17 is placed on the upper surface of the door rail 12. As a result, the landing door 10 is suspended from the door rail 12. When the door roller 17 rolls on the upper surface of the door rail 12, the movement of the landing door 10 is guided.

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 that protrudes upward in the receiving member 18. The receiving member 18 is provided on the surface 24 a of the mounting member 24. The surface 24a faces the hoistway 3 side. The attachment member 24 is provided on the hanger case 11. The attachment member 24 is disposed adjacent to the landing door 10. For example, the attachment member 24 is adjacent to the door hanger 16.

The locking member 19 is provided on the landing door 10 via the shaft 20. In the example shown in FIG. 3, the lock member 19 is provided on the door hanger 16. The lock member 19 is displaced about the shaft 20. For example, the lock member 19 can be arranged at the locking position and the unlocking position. The locking position is a position for locking the landing door 10. FIG. 3 shows an example in which the locking member 19 is arranged at the locking position. The lock member 19 has a facing portion 25. In the example shown in FIG. 3, the facing portion 25 is a portion of the lock member 19 that protrudes downward. When the locking member 19 is disposed at the locking position, the facing portion 25 faces the receiving portion 23 of the receiving member 18. When the landing door 10 moves in the opening direction from the fully closed position in a state where the locking member 19 is disposed at the locking position, the facing portion 25 contacts the receiving portion 23. This prevents the landing door 10 from being opened.

The unlocking position is a position for enabling the landing door 10 to be opened and closed. When the lock member 19 is disposed at the unlock position, the facing 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 always subjected to a force so as to be arranged at the lock position by a member such as a spring (not shown). For this reason, if an external force does not act on the locking device 13, the locking member 19 is arrange | positioned in a locking position.

The lower end of the arm 21 is provided on the shaft 20. The arm 21 extends upward from the shaft 20. For example, the upper end portion of the arm 21 is arranged on the left side in FIG. 3 with respect to the shaft 20 if no external force acts on the lock device 13. The roller 22 is rotatably provided at the upper end portion of the arm 21.

The roller 14 is rotatably provided on the landing door 10. 2 and 3 show an example in which the roller 14 is provided on the landing door 10 via the shaft 20. For example, the diameter of the roller 14 is the same as the diameter of the roller 22. The roller 22 is arranged on the left side in FIG. 3 with respect to the roller 14 when no external force is applied to the locking device 13. The roller 22 and the roller 14 are disposed at a position closer to the car 1 than the landing door 10 when the car 1 is stopped at the landing 9.

The car door device 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 the doorway formed in the car 1. In the following, the doorway formed in the car 1 is 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 the 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 on the door hanger 34.

The hanger case 27 is provided, for example, on a member that forms a cage. 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. Further, the door rail 28 is horizontally disposed in the direction of the entrance of the car. The door roller 35 is placed on the upper surface of the door rail 28. As a result, the car door 26 is suspended from the door rail 28. As the door roller 35 rolls on the upper surface of the door rail 28, the movement of the car door 26 is guided.

The motor 29 is supported by a hanger case 27, for example. The motor 29 generates a driving force for opening and closing the car door 26. The driving force of the motor 29 is transmitted to the car door 26 via a conversion device (not shown). The motor 29 is controlled by the control device 7.

The plate 30 and the plate 31 are provided on the car door 26. The plate 30 and the plate 31 are arranged in parallel at a predetermined interval so as to face each other. The plate 30 is arranged vertically so that the surface 30 a facing the plate 31 faces the opening direction of the car door 26. The plate 31 is arranged vertically so that the surface 31 a facing the plate 30 faces the closing direction of the car door 26. If the car 1 is stopped at the landing 9, the plate 30 and the plate 31 are disposed at a position closer to the landing 9 than the car door 26. When the car 1 stops at the landing 9, the rollers 14 and 22 are disposed between the plate 30 and the plate 31.

The sensor 32 is provided on the car door 26. FIG. 2 shows an example in which the sensor 32 is provided on the door hanger 34. The sensor 32 is a distance sensor, for example. For example, the sensor 32 outputs detection light horizontally toward the landing 9 and receives the reflected light. For example, the detection light from the sensor 32 is emitted in a direction orthogonal to the opening direction and the closing direction of the car door 26. The sensor 32 detects the distance to the object that has received 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 when the car 1 stops at the landing 9 will be described with reference to FIGS. 4 to 8 are diagrams for explaining the function of the landing door device and the function of the car door device.

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. For this reason, the facing portion 25 of the lock member 19 faces the receiving portion 23 of the receiving member 18. If the locking member 19 is disposed at the locking position, a gap having a width w <b> 1 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 placed in the fully closed position. Immediately after the car 1 stops at the landing 9, the roller 14 and the roller 22 are disposed between the plate 30 and the plate 31. At this time, the roller 14 and the roller 22 do not contact the plate 30 and the plate 31. If the car door 26 is disposed at the fully closed position, a gap having a width w <b> 2 is formed between the plate 30 and the roller 22. If the car door 26 is disposed at the fully closed position, a gap having a width w3 is formed between the plate 30 and the roller 14. The width w3 is larger than the width w2. X0 shown in FIGS. 4 to 8 indicates the position of the surface 30a of the plate 30 with respect to the moving direction of the car door 26 when the car door 26 is 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 plate 30 and the plate 31 are provided on the car door 26. For this reason, when the car door 26 moves in the opening direction, the plate 30 and the plate 31 also move in the opening direction. In the example shown in FIG. 4, the plate 30 moves so as to approach the roller 22.

When the plate 30 moves by the distance of the width w2, the plate 30 comes into contact with the roller 22. X1 shown in FIGS. 4 to 8 indicates the position of the end portion of the roller 22 with respect to the moving direction of the landing door 10 when the landing door 10 is disposed at the fully closed position. The end is the portion of the roller 22 that is closest to the plate 30. The position x1 corresponds to the first position of the car door 26.

FIG. 5 shows a state immediately after the plate 30 contacts the roller 22, that is, a state where the car door 26 has reached the first position. In the example shown in the present embodiment, the position where the surface 30a of the plate 30 reaches the position x1 is the first position of the car door 26. When the car door 26 moves further from the first position in the opening direction, the roller 22 is pushed by the plate 30. As a result, the shaft 20 rotates so that the roller 22 moves in the opening direction of the car door 26. The lock member 19 is fixed to the shaft 20. For this reason, when the axis | shaft 20 rotates, the locking member 19 rotates so that the opposing part 25 may move upwards. When the car door 26 reaches the first position from the fully closed position, the lock member 19 starts to move from the locked position to the unlocked position. That is, when the car door 26 exceeds the first position in the opening direction, the lock member 19 starts to move from the lock position to the unlock position.

FIG. 6 shows a state where the car door 26 is further moved in the opening direction from the state shown in FIG. 5 and the lock member 19 is detached from the receiving member 18. In the state shown in FIG. 6, the landing door 10 is still arranged at the fully closed position.

When the plate 30 moves by the distance of the width w3, the plate 30 contacts the roller 14. X2 shown in FIGS. 4 to 8 indicates the position of the end of the roller 14 with respect to the moving direction of the landing door 10 when the landing door 10 is disposed at the fully closed position. The end is the portion of the roller 14 that is closest to the plate 30. The position x2 corresponds to the second position of the car door 26. The second position is a position farther from the fully closed position than the first position.

FIG. 7 shows a state immediately after the plate 30 contacts the roller 14, that is, a state where the car door 26 has reached the second position. In the example shown in the present embodiment, the position where the surface 30a of the plate 30 reaches the position x2 is the second position of the car door 26. In the state shown in FIG. 7, the lock member 19 is disposed at the unlock position. When the car door 26 moves further in the opening direction from the second position, the roller 14 is pushed by the plate 30. The roller 14 is provided on a shaft 20 fixed to the landing door 10. For this reason, after the plate 30 contacts the roller 14, the landing door 10 moves in the opening direction together with the car door 26. When the car door 26 reaches the second position from the fully closed position beyond the first position, the movement of the landing door 10 in the opening direction is started. That is, when the car door 26 exceeds the second position in the opening direction, the landing door 10 starts to move in the opening direction. FIG. 8 shows a state where the car door 26 is further moved in the opening direction from the state shown in FIG. In the example shown in the present embodiment, the roller 14, the plate 30, and the plate 31 constitute an apparatus for interlocking the landing door 10 with the car door 26.

Next, the detection target of the sensor 32 will be described in detail. 9 to 12 are diagrams for explaining the function of the sensor 32. FIG. 9 shows a state immediately after the plate 30 contacts the roller 22, that is, a state where the car door 26 reaches the first 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 where the detection light emitted from the sensor 32 hits immediately after the car 1 stops at the landing 9. As shown in FIG. 9, if the car door 26 is disposed at the fully closed position when the car 1 is stopped at the landing 9, the facing portion 25 becomes a detection target of the sensor 32. That is, the detection light emitted from the sensor 32 strikes the facing portion 25. Thereby, the distance to the facing portion 25 is detected by the sensor 32. 10 to 12 are diagrams corresponding to the DD section of FIG. FIG. 10 shows a cross section when the car door 26 is located at the fully closed position.

As described above, the sensor 32 is provided on the car door 26. For this reason, 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 first position, the position where the detection light emitted from the sensor 32 hits the object changes as indicated by an arrow C in FIG. As shown in FIG. 9, before the car door 26 reaches the first position, the facing portion 25 is removed from the detection target of the sensor 32. FIG. 11 shows a cross section when the facing portion 25 is out of the detection target of the sensor 32. At this time, the detection light emitted from the sensor 32 passes between the facing portion 25 and the receiving portion 23 and strikes the surface 24 a of the mounting member 24. That is, the detection target of the sensor 32 changes from the facing portion 25 to the mounting member 24. Thereby, the distance to the attachment member 24 is detected by the sensor 32.

When the car door 26 further moves in the opening direction from the state shown in FIG. 11, the receiving portion 23 becomes a detection target of the sensor 32 before the car door 26 reaches the first position. That is, the detection light emitted from the sensor 32 strikes the receiving portion 23. Thereby, the distance to the receiving portion 23 is detected by the sensor 32. FIG. 12 shows a cross section when the car door 26 reaches the first position. As described above, when the car door 26 exceeds the first position in the opening direction, the movement of the locking member 19 from the locking position to the unlocking position is started. The movement of the locking member 19 is not started before the car door 26 reaches the first position.

FIG. 13 is a diagram illustrating 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 reference range is stored in the storage unit 36 in advance. This reference range is used to determine whether or not an abnormality has occurred in the lock device 13.

Hereinafter, the operation for measuring the distance between the receiving portion 23 of the receiving member 18 and the facing portion 25 of the locking member 19 will be described with reference to FIG. FIG. 14 is a flowchart showing an operation example of the elevator apparatus according to Embodiment 1 of the present invention. FIG. 14 shows an example in which the distance is measured by a diagnostic operation.

In the control device 7, it is determined whether or not a diagnosis operation start condition is satisfied (S101). The diagnosis operation is performed periodically, for example. For example, the control device 7 determines that the diagnostic operation start condition is satisfied if a specific date and time are reached and no person is on the car 1. Other conditions may be adopted as the starting conditions for the diagnostic operation. The start condition is stored in advance in the storage unit 36. When the start condition is satisfied, the control device 7 starts the diagnostic operation (S102). The diagnostic operation is controlled by the operation control unit 39, for example.

The operation control unit 39 first stops the car 1 at the landing 9 (S103). When the car 1 stops at the landing 9, the distance detection 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. For this reason, the detection light from the sensor 32 strikes the facing portion 25. A distance to the facing portion 25 is detected by the sensor 32.

When the detection by the sensor 32 is started, the operation control unit 39 moves the car door 26 in the opening direction (S105). As described above, even when the opening operation of the car door 26 is started, the locking device 13 does not move until the car door 26 reaches the first position. The lock member 19 remains in the locked position. Further, until the car door 26 reaches the first 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 until at least the receiving portion 23 becomes a detection target of the sensor 32. For example, when the car door 26 reaches the first position, the distance detection by the sensor 32 ends (S106). The detection of the distance by the sensor 32 may be terminated when the car door 26 reaches the second position. The detection of the distance by the sensor 32 may be terminated after the car door 26 has passed the second position. As another example, the detection of the distance by the sensor 32 may be terminated based on the elapsed time after the opening operation of the car door 26 is started.

The calculating part 37 calculates the distance between the receiving part 23 of the receiving member 18 and the facing part 25 of the locking member 19 based on the result detected by the sensor 32 (S107). FIG. 15 is a diagram illustrating an example of a result detected by the sensor 32. In FIG. 15, time t0 is the time when the opening operation of the car door 26 is started. Time t3 is the time when the car door 26 reaches the first position. FIG. 15 shows that the facing portion 25 is excluded from the detection target of the sensor 32 at time t1. Similarly, it shows that the receiving unit 23 is a detection target of the sensor 32 at time t2. The moving speed of the car door 26 is known. The calculation unit 37 obtains the distance between the receiving unit 23 and the facing unit 25 based on the time required from when the facing unit 25 is removed from the detection target of the sensor 32 until the receiving unit 23 is detected by the sensor 32. be able to.

The determination unit 38 determines whether the distance calculated by the calculation unit 37 is within the reference range stored in the storage unit 36 (S108). If the distance calculated by the calculation unit 37 is not within the reference range, the determination unit 38 detects that an abnormality has occurred in the lock device 13 (S109). For example, if the facing portion 25 and the receiving portion 23 are too close to each other, the facing portion 25 is caught by the receiving portion 23 when the lock member 19 is displaced from the locking position to the unlocking position. In such a case, the landing door 10 and the car door 26 cannot be opened. If a person is in the car 1, the person is locked in the car 1.

The operation control unit 39 may perform a predetermined operation when an abnormality is detected by the determination unit 38. For example, when an abnormality is detected by the determination unit 38, the operation control unit 39 displays on the display (not shown) provided in the car 1 that the abnormality has been detected. When the determination unit 38 detects an abnormality, the operation control unit 39 may notify the outside that the abnormality has been detected. When an abnormality is detected by the determination unit 38, the operation control unit 39 may store in the storage unit 36 that the abnormality has been detected.

The processing shown in S103 to S109 is performed on the lock device 13 provided in each hall 9. When the processing shown in S103 to S109 is performed on the lock device 13 provided at a certain landing 9, it is determined whether or not distance measurement has been performed on all the lock devices 13 (S110). If there is a lock device 13 for which the distance is not measured, the car 1 is stopped at the landing 9 where the lock device 13 is located.

In the example shown in the present embodiment, the gap necessary for the lock device 13, that is, the distance between the receiving portion 23 and the facing portion 25 can be measured easily and accurately.

In the present embodiment, an example in which the sensor 32 is a distance sensor has been described. This is an example. For example, a sensor cheaper than the distance sensor may be used as the sensor 32. Although the distance to the object cannot be detected as the sensor 32, a sensor that can detect the presence or absence of an object based on certain conditions may be used. For example, the sensor 32 outputs detection light and detects the presence or absence of an object based on the reflected light.

For example, if the car door 26 is located at the fully closed position when the car 1 is stopped at the landing 9, the detection light emitted from the sensor 32 strikes the facing portion 25. When the car door 26 moves in the opening direction from the fully closed position, the facing portion 25 is removed from the detection target of the sensor 32 before the car door 26 reaches the first position. When the car door 26 moves in the opening direction from the fully closed position, the receiving portion 23 is detected by the sensor 32 before the car door 26 reaches the first position after the facing portion 25 is removed from the detection target of the sensor 32. It becomes. That is, the detection light emitted from the sensor 32 strikes the receiving portion 23. The calculating 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.

As in the example shown in the present embodiment, when a part of the attachment member 24 is disposed between the facing portion 25 and the receiving portion 23 as viewed from the sensor 32 side, the facing portion 25 is the sensor 32. The mounting member 24 becomes the detection target of the sensor 32 after being removed from the detection target. In such a case, a process for suppressing the reflection of the detection light may be performed on the portion of the attachment member 24 where the detection light from the sensor 32 strikes. For example, an antireflection process is performed on the portion. Non-reflective treatment includes performing coating for non-reflective and applying a non-reflective sheet.

In the present embodiment, the example in which the determination unit 38 performs only the determination shown in S108 has been described. This is an example. For example, the determination unit 38 may determine whether or not a deviation has occurred in the stop position of the car 1 based on the result detected by the sensor 32. Such a determination is made after the determination shown in S108, for example.

FIG. 16 is a view of the lock device 13 as viewed from the car 1 side. FIG. 16 corresponds to FIG. 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 hits the position of the point B1 shown in FIG. When the car door 26 moves in the opening direction from the state where the detection light hits the point B1, the position where the detection light emitted from the sensor 32 hits the object changes as shown by an arrow C1 in FIG. At this time, the receiving portion 23 is not a detection target of the sensor 32. FIG. 17 is a diagram illustrating an example of a result detected by the sensor 32. FIG. 17 shows a result when the position where the detection light hits the object changes as indicated by an arrow C1. The determination unit 38 determines, for example, that the stop position of the car 1 is shifted upward when the receiving unit 23 is not the detection target of the sensor 32 after the facing unit 25 is the detection target of the sensor 32. Also good.

As another example, if 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 hits the position of point B2 shown in FIG. That is, the detection light emitted from the sensor 32 strikes the attachment member 24. When the car door 26 moves in the opening direction from the state where the detection light hits the point B2, the position where the detection light emitted from the sensor 32 hits the object changes as shown by an arrow C2 in FIG. At this time, the facing 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 first position. FIG. 18 is a diagram illustrating an example of a result detected by the sensor 32. FIG. 18 shows a result when the position where the detection light hits the object changes as indicated by an arrow C2. For example, the determination unit 38 determines that the stop position of the car 1 is shifted downward when the receiving unit 23 is a detection target of the sensor 32 without the facing unit 25 being a detection target of the sensor 32. Also good.

In the present embodiment, the example in which the receiving portion 23 is the detection target of the sensor 32 before the car door 26 reaches the first position has been described. This is an example. The timing at which the receiving portion 23 is detected by the sensor 32 may be after the car door 26 has reached the first position. As described above, when the car door 26 reaches the first position from the fully closed position, the movement of the lock member 19 to the unlock position is started. However, even if the car door 26 reaches the first position, the receiving member 18 does not move. For this reason, if the detection light is not blocked by the lock member 19 even if the movement of the lock member 19 is started as in the example shown in the present embodiment, the receiving portion is received after the car door 26 reaches the first position. 23 may be a detection target of the sensor 32.

As another example, the distance between the receiving portion 23 and the facing portion 25 may be measured without opening the landing door 10. In such a case, if the car door 26 moves in the opening direction when the car 1 is stopped at the landing 9, at least the receiving portion 23 needs to be a detection target of the sensor 32 before the car door 26 reaches the second position. is there. The operation control unit 39 may move the car door 26 in the closing direction before the car door 26 reaches the second position after the car door 26 is opened in S105, for example. Thereby, the distance between the receiving portion 23 and the facing portion 25 can be obtained without moving the landing door 10.

Each part indicated by reference numerals 36 to 39 represents a function of the control device 7. FIG. 19 is a diagram illustrating a hardware configuration of the control device 7. The control device 7 includes a processing circuit including, for example, a processor 40 and a memory 41 as hardware resources. The functions of the storage unit 36 are realized by the memory 41. The control device 7 executes the program stored in the memory 41 by the processor 40, thereby realizing the functions of the units indicated by reference numerals 37 to 39. Some or all of the functions of the control device 7 may be realized by hardware.
