DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Embodiment 1 Fig. 1 is a configuration diagram showing an elevator according to embodiment 1. The elevator according to embodiment 1 includes a car 1, a counterweight 2, a main rope 3, a hoist 4, a car-use occupant detection device 5, a counterweight-use occupant detection device 6, a tensioner-use occupant detection device 7, a pit alarm device 8, and an elevator control panel 9.

[0010] The car 1 and the counterweight 2 are provided in a hoistway 10. One longitudinal end of a main rope 3 is connected to the car 1. The other longitudinal end of the main rope 3 is connected to the counterweight 2. The car 1 and the counterweight 2 are suspended in the hoistway 10 via the main rope 3.

[0011] The hoisting machine 4 is provided in the machine room 11. The longitudinal middle portion of the main rope 3 is wound around the hoisting machine 4. The hoisting machine 4 is driven to move the main rope 3. The movement of the main rope 3 causes the car 1 and the counterweight 2 to move along the hoistway 10.

[0012] Fig. 2 is a front view showing the car 1 of Fig. 1. Fig. 2 shows a state seen from inside the car 1. The car 1 has a car body 101, an in-car operation panel 102, and an in-car notification device 103.

[0013] Elevator users or workers enter and exit the car body 101. An in-car operation panel 102 and an in-car notification device 103 are each provided in the car body 101.

[0014] The car operation panel 102 has a plurality of destination floor buttons. The car operation panel 102 is operated by an elevator user or an operator in the car body 101.

[0015] In elevator maintenance and inspection, methods for a worker in car 1 to move car 1 by operating the in-car operation panel 102 include moving car 1 by automatic operation and moving car 1 by manual operation.

[0016] The movement of the car 1 by automatic operation is performed by an operator operating a destination floor button on the car operation panel 102. When the car 1 is moved by automatic operation, the car 1 moves to the landing of the floor corresponding to the operated destination floor button.

[0017] Movement of the car 1 by manual operation is performed by an operator performing a special operation of the destination floor button on the in-car operation panel 102. When moving the car 1 by manual operation, the car 1 moves upward or downward for the period during which the special operation is being performed. Note that movement of the car 1 by manual operation is not limited to the special operation of the destination floor button. For example, if the in-car operation panel 102 has a manual operation button, movement of the car 1 by manual operation may be performed by an operator operating the manual operation button on the in-car operation panel 102.

[0018] The car internal notification device 103 is composed of a speaker device. The car internal notification device 103 notifies the worker in the car 1 of preset notification contents by emitting a sound. The preset notification contents include, for example, the presence of a worker in the pit 12, the presence of a worker in the car detection area 13, the presence of a worker in the counterweight detection area 14, and the presence of a worker in the tension car detection area 15.

[0019] The car internal notification device 103 is not limited to a speaker device, and may be configured, for example, as a display device. In this configuration, the car internal notification device 103 notifies the worker in the car 1 of preset notification content by displaying characters or the like on a screen.

[0020] The pit notification device 8 is composed of a speaker device. The pit notification device 8 notifies the workers in the pit 12 of preset notification contents by emitting a sound. Examples of the preset notification contents include that the car internal operation panel 102 has been operated so that the car 1 moves downward by manual operation, that the car internal operation panel 102 has been operated so that the counterweight 2 moves downward by manual operation, and that the car internal operation panel 102 has been operated so that the car 1 moves by manual operation.

[0021] The pit notification device 8 is not limited to a speaker device, and may be configured, for example, as a display device. In this configuration, the pit notification device 8 notifies the workers in the pit 12 of preset notification content by displaying characters or the like on a screen.

[0022] The car occupant detection device 5, the counterweight occupant detection device 6, and the tension car occupant detection device 7 are each provided in a pit 12 of the hoistway 10.

[0023] FIG. 3 is a plan view showing the area in which the car-use person detection device 5 in FIG. 1 detects an operator, the area in which the counterweight-use person detection device 6 detects an operator, and the area in which the tensioner-use person detection device 7 detects an operator.

[0024] The car person detection device 5 detects a worker in the car detection area 13. The car detection area 13 is an area in the pit 12 where the car 1 can enter.

[0025] The counterweight human detection device 6 detects a worker in the counterweight detection area 14. The counterweight detection area 14 is an area in the pit 12 where the counterweight 2 can enter.

[0026] The tension wheel human detection device 7 detects a worker in the tension wheel detection area 15. The tension wheel detection area 15 is an area adjacent to a tension wheel (not shown) in the pit 12. Examples of the tension wheel include a tension wheel around which the main rope 3 is wound and a tension wheel around which the governor rope is wound.

[0027] Fig. 4 is a block diagram showing an elevator according to embodiment 1. An elevator control panel 9 is electrically connected to an in-car operation panel 102, an in-car alarm device 103, a hoist 4, a car occupant detection device 5, a counterweight occupant detection device 6, a tension car occupant detection device 7, and a pit alarm device 8. The detection results of the car occupant detection device 5, the counterweight occupant detection device 6, and the tension car occupant detection device 7 are input to the elevator control panel 9.

[0028] When the car in-operation panel 102 is operated, the elevator control panel 9 controls the driving of the hoist 4 and controls the movement of the car 1 based on the detection results of the car occupant detection device 5, the counterweight occupant detection device 6, and the tension car occupant detection device 7. In addition, when the car in-operation panel 102 is operated, the elevator control panel 9 controls the notifications of the car in-notification device 103 and the pit notification device 8 based on the detection results of the car occupant detection device 5, the counterweight occupant detection device 6, and the tension car occupant detection device 7.

[0029] Next, the operation of the elevator when maintenance inspection is being performed will be described. Fig. 5 is a flowchart showing the operation of the elevator according to the embodiment 1. First, in step S101, the elevator control panel 9 determines whether or not the in-car operation panel 102 for moving the car 1 by automatic operation has been operated.

[0030] If, in step S101, the elevator control panel 9 determines that an operation has been performed on the in-car operation panel 102 for moving the car 1 through automatic operation, then in step S102, an automatic operation-related process is performed, and after the automatic operation-related process, the operation of the elevator in the case where maintenance and inspection are being performed is terminated.

[0031] If, in step S101, the elevator control panel 9 determines that the in-car operation panel 102 has not been operated for moving the car 1 by automatic operation, in step S103, the elevator control panel 9 determines whether or not the in-car operation panel 102 has been operated for moving the car 1 by manual operation.

[0032] If, in step S103, the elevator control panel 9 determines that an operation has been performed on the in-car operation panel 102 for moving the car 1 by manual operation, then in step S104, a manual operation related process is performed, and after the manual operation related process, the operation of the elevator in the case where maintenance and inspection are being performed is terminated.

[0033] If, in step S104, the elevator control panel 9 determines that no operation has been performed on the in-car operation panel 102 for manually moving the car 1, the operation of the elevator during maintenance inspection is terminated.

[0034] Fig. 6 is a flow chart showing the automatic driving related process of Fig. 5. In the automatic driving related process, in step S201, a process of determining the presence or absence of a worker in the pit is performed.

[0035] In the process of determining whether or not there is a worker in the pit, the elevator control panel 9 determines whether or not there is a worker in the pit 12. Specifically, the elevator control panel 9 determines whether or not there is a worker in the car detection area 13 based on the detection result of the car human detection device 5. The elevator control panel 9 also determines whether or not there is a worker in the counterweight detection area 14 based on the detection result of the counterweight human detection device 6. The elevator control panel 9 also determines whether or not there is a worker in the tension wheel detection area 15 based on the detection result of the tension wheel human detection device 7.

[0036] That is, when the elevator control panel 9 determines that an operator is present in any of the car detection area 13, the counterweight detection area 14, and the tension wheel detection area 15, the elevator control panel 9 determines that an operator is present in the pit 12. On the other hand, when the elevator control panel 9 determines that an operator is not present in any of the car detection area 13, the counterweight detection area 14, and the tension wheel detection area 15, the elevator control panel 9 determines that an operator is not present in the pit 12.

[0037] In step S201, if the elevator control panel 9 determines that there is no worker in the pit 12, an automatic car movement process is performed in step S202.

[0038] In the automatic operation car movement process, the elevator control panel 9 moves the car 1 by automatic operation. After the automatic operation car movement process, the automatic operation related process ends.

[0039] If the elevator control panel 9 determines in step S201 that there is an operator in the pit 12, an automatic operation restriction process is performed in step S203.

[0040] In the automatic operation limiting process, the elevator control panel 9 limits the movement of the car 1 by automatic operation. Also, in the automatic operation limiting process, the car informing device 103 notifies the worker in the car 1 that there is a worker in the pit 12. After the automatic operation limiting process, the automatic operation related process ends.

[0041] Fig. 7 is a flow chart showing the manual driving related process of Fig. 5. In the manual driving related process, in step S301, a process of determining the presence or absence of a worker in the pit is carried out.

[0042] In the process of determining whether or not there is a worker in the pit, the elevator control panel 9 determines whether or not there is a worker in the pit 12. Specifically, the elevator control panel 9 determines whether or not there is a worker in the car detection area 13 based on the detection result of the car human detection device 5. The elevator control panel 9 also determines whether or not there is a worker in the counterweight detection area 14 based on the detection result of the counterweight human detection device 6. The elevator control panel 9 also determines whether or not there is a worker in the tension wheel detection area 15 based on the detection result of the tension wheel human detection device 7.

[0043] That is, when the elevator control panel 9 determines that an operator is present in any of the car detection area 13, the counterweight detection area 14, and the tension wheel detection area 15, the elevator control panel 9 determines that an operator is present in the pit 12. On the other hand, when the elevator control panel 9 determines that an operator is not present in any of the car detection area 13, the counterweight detection area 14, and the tension wheel detection area 15, the elevator control panel 9 determines that an operator is not present in the pit 12.

[0044] In step S301, if the elevator control panel 9 determines that there is no worker in the pit 12, a manual car movement process is performed in step S302.

[0045] In the manual operation car movement process, the elevator control panel 9 moves the car 1 by manual operation. After the manual operation car movement process, the manual operation related process ends.

[0046] In step S301, when the elevator control panel 9 determines that an operator is present in the pit 12, a car downward movement determination process is performed in step S303. In the car downward movement determination process, the elevator control panel 9 determines whether or not an operator is present in the car detection area 13.

[0047] In step S303, when elevator control panel 9 determines that an operator is present in car detection area 13, a car downward movement limiting step is performed in step S304.

[0048] In the car downward movement limiting process, the elevator control panel 9 limits the downward movement of the car 1 by manual operation. Also, in the car downward movement limiting process, the car in-cabin alarm device 103 notifies the worker in the car 1 that a worker is in the car detection area 13. Also, in the car downward movement limiting process, the pit alarm device 8 notifies the worker in the pit 12 that the car in-cabin operation panel 102 has been operated so as to move the car 1 downward by manual operation. After the car downward movement limiting process, the manual operation related process ends.

[0049] In step S303, when the elevator control panel 9 determines that there is no worker in the car detection area 13, a counterweight downward movement determination step is performed in step S305. In the counterweight downward movement determination step, the elevator control panel 9 determines whether there is a worker in the counterweight detection area 14.

[0050] In step S305, when elevator control panel 9 determines that an operator is present in counterweight detection area 14, a counterweight downward movement limiting step is performed in step S306.

[0051] In the counterweight downward movement limiting process, the elevator control panel 9 limits the upward movement of the car 1 due to manual operation. Also, in the counterweight downward movement limiting process, the car in-notification device 103 notifies the worker in the car 1 that a worker is in the counterweight detection area 14. Also, in the counterweight downward movement limiting process, the pit in-notification device 8 notifies the worker in the pit 12 that the car in-operation panel 102 has been operated so that the counterweight 2 moves downward by manual operation. After the counterweight downward movement limiting process, the manual operation related process ends.

[0052] In step S305, when the elevator control panel 9 determines that there is no worker in the counterweight detection area 14, the elevator control panel 9 determines that there is a worker in the tension wheel detection area 15. In this case, a car movement restriction process is performed in step S307.

[0053] In the car movement limiting process, the elevator control panel 9 limits the movement of the car 1 by manual operation. Also, in the car movement limiting process, the car in-notification device 103 notifies the worker in the car 1 that a worker is in the tensioner detection area 15. Also, in the car movement limiting process, the pit notification device 8 notifies the worker in the pit 12 that the car in-car operation panel 102 has been operated so as to move the car 1 by manual operation. After the car movement limiting process, the manual operation related process ends.

[0054] As described above, the elevator according to the first embodiment includes the car occupant detection device 5, the counterweight occupant detection device 6, and the elevator control panel 9. The car occupant detection device 5 detects an operator in the car detection area 13 in the pit 12. The counterweight occupant detection device 6 detects an operator in the counterweight detection area 14 in the pit 12. The elevator control panel 9 restricts the movement of the car 1 based on the detection results of the car occupant detection device 5 and the counterweight occupant detection device 6. When the car occupant detection device 5 detects an operator, the elevator control panel 9 restricts the downward movement of the car 1 by manual operation. Also, when the counterweight occupant detection device 6 detects an operator, the elevator control panel 9 restricts the upward movement of the car 1 by manual operation. According to this configuration, the cage 1 can be moved manually while an operator is present in the pit 12, and the cage 1 or counterweight 2 can be prevented from coming into contact with the operator in the pit 12.

[0055] Furthermore, in the elevator according to the first embodiment, when the car occupant detection device 5 detects an operator, or when the counterweight occupant detection device 6 detects an operator, the elevator control panel 9 restricts the movement of the car 1 by automatic operation. With this configuration, it is possible to prevent the car 1 from moving by automatic operation when an operator is present in the pit 12.

[0056] Moreover, in the elevator according to the first embodiment, the car 1 has a car body 101, an in-car operation panel 102 provided in the car body 101, and an in-car notification device 103 provided in the car body 101. When the car occupant detection device 5 detects an operator and the in-car operation panel 102 is operated by manual operation so that the car 1 moves downward, the in-car notification device 103 notifies the operator in the car 1 that an operator is present in the car detection area 13. When the counterweight occupant detection device 6 detects an operator and the in-car operation panel 102 is operated by manual operation so that the car 1 moves upward, the in-car notification device 103 notifies the operator in the car 1 that an operator is present in the counterweight detection area 14. According to this configuration, it is possible to notify an operator who operates the car internal operation panel 102 so as to move the car 1 downward by manual operation that an operator is present in the car detection area 13. Also, it is possible to notify an operator who operates the car internal operation panel 102 so as to move the car 1 upward by manual operation that an operator is present in the counterweight detection area 14.

[0057] Furthermore, in the elevator according to embodiment 1, when the car occupant detection device 5 detects an operator or when the counterweight occupant detection device 6 detects an operator and the car operation panel 102 is operated to move the car 1 by automatic operation, the car informing device 103 notifies the operator in the car 1 that there is an operator in the pit 12. According to this configuration, it is possible to notify the operator in the car 1 that there is an operator in the pit 12 and that the car 1 will not move even if the car operation panel 102 is operated to move the car 1 by automatic operation.

[0058] Moreover, the elevator according to the first embodiment is equipped with a tension wheel human detection device 7. The tension wheel human detection device 7 detects an operator in a tension wheel detection area 15 in the pit 12. When the tension wheel human detection device 7 detects an operator, the elevator control panel 9 restricts the movement of the car 1 by manual operation and restricts the movement of the car 1 by automatic operation. With this configuration, it is possible to prevent the moving tension wheel from coming into contact with the operator in the pit 12.

[0059] Moreover, the elevator according to the first embodiment includes a pit alarm device 8 provided in the pit 12. When the car-use occupant detection device 5 detects an operator and the car-use operation panel 102 is operated so that the car 1 moves downward by manual operation, the pit alarm device 8 notifies the operator in the pit 12 that the car-use operation panel 102 has been operated so that the car 1 moves downward by manual operation. When the counterweight-use occupant detection device 6 detects an operator and the car-use operation panel 102 is operated so that the car 1 moves upward by manual operation, the pit alarm device 8 notifies the operator in the pit 12 that the car-use operation panel 102 has been operated so that the car 1 moves upward by manual operation. With this configuration, it is possible to notify the operator in the car detection area 13 that the car-use operation panel 102 has been operated so that the car 1 moves downward by manual operation. In addition, it is possible to notify an operator in the counterweight detection area 14 that the car internal operation panel 102 has been operated so as to move the car 1 upward by manual operation.

[0060] In the elevator according to the first embodiment, a configuration has been described in which the elevator is provided with the car-use occupant detection device 5, the counterweight-use occupant detection device 6, and the tension wheel-use occupant detection device 7. However, this is not limited thereto. For example, the elevator may be provided with only the car-use occupant detection device 5 and the counterweight-use occupant detection device 6 without providing the tension wheel-use occupant detection device 7.

[0061] Also, in the elevator according to the first embodiment, when it is determined that an operator is present in the pit 12, that an operator is not present in the car detection area 13, and that an operator is not present in the counterweight detection area 14 during the manual operation car movement process, the elevator control panel 9 determines that an operator is present in the tension wheel detection area 15. However, this is not limited to this. The elevator control panel 9 may be configured to determine whether or not an operator is present in the tension wheel detection area 15 based on the detection result of the tension wheel human detection device 7 after it is determined that an operator is present in the pit 12 during the manual operation car movement process.

[0062] Although the elevator according to the preferred embodiment 1 has been described above, the elevator is not limited to the elevator according to the above-mentioned embodiment 1.
