[0010] The embodiments for carrying out the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are denoted by the same reference numerals. The duplicated description of the parts will be appropriately simplified or omitted.

[0011] Embodiment 1 1 and 2 are configuration diagrams of a building to which the elevator device according to the first embodiment is applied.

[0012] The elevator device 1 in FIG. 1 is installed in a building (not shown). A hoistway 2 passes through each floor of the building. A machine room 3 is provided directly above the hoistway 2. A plurality of landings 4 are provided on each floor of the building. Each of the plurality of landings 4 faces the hoistway 2. A pair of guide rails 5 are provided inside the hoistway 2. The longitudinal direction of the pair of guide rails 5 faces the vertical direction. A hoisting machine 6 is provided in the machine room 3. A main rope 7 is wound around the hoisting machine 6.

[0013] The car 8 is provided inside the hoistway 2. The car 8 is between the pair of guide rails 5 and adjacent to each of the pair of guide rails 5. The car 8 is hung on one side of the main ropes 7. The counterweight 9 is provided inside the hoistway 2. The counterweight 9 is hung on the other side of the main ropes 7.

[0014] The car 8 is provided with a plurality of guide shoes 10 as a plurality of guide bodies. For example, the car 8 is provided with four guide shoes 10. Two of the four guide shoes 10 are provided on an upper portion of the car 8. The remaining two of the four guide shoes 10 are provided on a lower portion of the car 8. Each of the four guide shoes 10 is adjacent to one of the pair of guide rails 5.

[0015] The control panel 11 is provided in the machine room 3. The control panel 11 can overall control the operation of the elevator apparatus 1. The monitoring device 12 is provided in the machine room 3. The monitoring device 12 is electrically connected to the control panel 11. Although not shown, the monitoring device 12 can communicate with a device provided in a management center which is a company that maintains the elevator apparatus 1.

[0016] The elevator apparatus 1 further includes a position detection device 20. The position detection device 20 can detect the position of the car 8 inside the hoistway 2. The position detection device 20 includes a plurality of detection units 21 and a controller 22.

[0017] Each of the multiple detection units 21 has the same configuration as a sensor that detects pressure. The multiple detection units 21 are each fixed to one of the pair of guide rails 5. The multiple detection units 21 are each arranged at a height corresponding to the multiple landings 4. The multiple detection units 21 are each arranged at a specified interval. One of the multiple detection units 21 may be provided at the lowest position to which the car 8 can move. One of the multiple detection units 21 may be provided at the highest position to which the car 8 can move.

[0018] The controller 22 is provided inside the control panel 11. The controller 22 is electrically connected to the control panel 11 and the monitoring device 12. The controller 22 is electrically connected to each of the multiple detection units 21. Although not shown, the controller 22 may be electrically connected to a safety monitoring device of the car 8.

[0019] When the elevator device 1 operates normally, the control panel 11 rotates the hoist 6. The main rope 7 moves following the rotation of the hoist 6. The car 8 and the counterweight 9 rise and fall in opposite directions following the movement of the main rope 7. At this time, each of the guide shoes 10 guides the car 8 so that the car 8 moves along the pair of guide rails 5. Specifically, the guide shoes 10 fixed to the car 8 come into contact with the guide rails 5 to limit the horizontal movement of the car 8. The control panel 11 stops the car 8 at the landing position of the hall 4.

[0020] 2 shows a state in which the car 8 has reached the landing position of the hall 4. In this state, one of the four guide shoes 10 comes into contact with the detection unit 21 corresponding to that hall 4. The detection unit 21 detects pressure from the guide shoe 10. The detection unit 21 transmits a signal indicating the detected pressure to the controller 22.

[0021] When the controller 22 receives a signal from the detection unit 21, it identifies the position where the detection unit 21 is installed. The controller 22 detects that the car 8 is present at the identified position. The controller 22 transmits information on the position of the car 8 to the control panel 11. The control panel 11 detects, based on the information from the controller 22, that the car 8 has reached the landing position of the hall 4. The control panel 11 stops the car 8.

[0022] The controller 22 accumulates the signal information received from the detection unit 21 in the accumulation section. The controller 22 performs an abnormality diagnosis on the detection unit 21 based on the accumulated signal information and the signal from the detection unit 21. If an abnormality occurs in any of the multiple detection units 21 as a result of the abnormality diagnosis, the controller 22 can detect the abnormality. If the controller 22 detects the abnormality, it sends a command to the control panel 11 to stop the car 8. In this case, the control panel 11 takes measures such as stopping the car 8 at the nearest floor. Furthermore, if the controller 22 detects the abnormality, it notifies a device installed in the management center via the monitoring device 12 that an abnormality has been detected.

[0023] Next, the guide rail 5, the guide shoe 10, and the detection unit 21 will be described with reference to FIGS. Fig. 3 is a horizontal cross-sectional view of a main part of the elevator device in embodiment 1. Specifically, Fig. 3 shows a cross-section taken along line AA in Fig. 2. Fig. 4 is an enlarged horizontal cross-sectional view of a main part of the elevator device in embodiment 1.

[0024] 3, the guide rail 5 includes a flange portion 5a and a head portion 5b. Although not shown, the flange portion 5a is fixed to the wall surface of the hoistway 2 by a bracket. In a horizontal cross section, the head portion 5b extends from the center of the flange portion 5a toward the inside of the hoistway 2. The head portion 5b has a surface facing the direction toward the car 8 in the extension direction, and two side surfaces perpendicular to the surface facing the direction toward the car 8.

[0025] The detection unit 21 includes a detector 23 , a signal line 24 , and a holder 25 .

[0026] The detector 23 is disposed on the surface of the head portion 5b of the guide rail 5. The detector 23 contacts a first surface 5c which is a side surface of the head portion 5b. A signal line 24 is drawn out from the detector 23. The signal line 24 is connected to a controller 22 which is not shown in FIG.

[0027] The holder 25 holds the detector 23 at the position shown in FIG. 3. The holder 25 includes a first holder 25a and a second holder 25b. The first holder 25a is detachably fixed to the flange 5a of the guide rail 5. For example, the second holder 25b has an L-shape. One end of the second holder 25b is fixed to the first holder 25a. The other end of the second holder 25b is fixed to the detector 23.

[0028] For example, in a horizontal cross section, the shape of the guide shoe 10 is U-shaped. The guide shoe 10 is disposed so that the head 5b of the guide rail 5 is located inside the U-shaped groove. The guide shoe 10 has a guide portion 10a which is a first guide portion, and a pressing portion 10b which is a first pressing portion.

[0029] A part of the guide portion 10a faces the first surface 5c. The guide portion 10a is a part of the inner surface of the U-shaped groove. When the car 8 moves, the guide portion 10a comes into contact with the guide rail 5. The pressing portion 10b is provided in a position facing the detector 23 on the inside of the U-shaped groove. The pressing portion 10b is a notch provided on the inside of the guide shoe 10. Specifically, the pressing portion 10b is a recessed portion of the inner surface of the U-shaped groove. For example, the depth of the recess of the pressing portion 10b is equal to the thickness of the detector 23. In the state of FIG. 3, the pressing portion 10b faces the first surface 5c of the guide rail 5.

[0030] As shown in FIG. 4, the detector 23 includes a pressure sensing body 26 and a cover body 27 .

[0031] The pressure detecting body 26 is a sensor that detects pressure. Specifically, the pressure detecting body 26 is a semiconductor strain gauge. When the pressure detecting body 26 is subjected to pressure, strain is generated in the pressure detecting body 26. The pressure detecting body 26 detects a change in internal resistance caused by the strain. The pressure detecting body 26 transmits an electrical signal corresponding to the change in internal resistance as a signal indicating that pressure has been received.

[0032] The covering 27 is provided around the pressure sensing body 26. The covering 27 covers the surface of the pressure sensing body 26, thereby protecting the surface of the pressure sensing body 26. The covering 27 can transmit the pressure received on the surface to the pressure sensing body 26.

[0033] 3 and 4, the surface of guide portion 10a on which detector 23 is provided comes into contact with first surface 5c of guide rail 5. Detector 23 comes into contact with the bottom surface of the recess in pressing portion 10b. At this time, detector 23 receives pressure from pressing portion 10b while being sandwiched between guide rail 5 and pressing portion 10b. Pressure detector 26 transmits an electric signal to controller 22.

[0034] Next, the control performed in the elevator device 1 will be described with reference to FIG. FIG. 5 is a flowchart for illustrating an overview of the operation of the elevator system in the first embodiment.

[0035] FIG. 5 shows a flow chart of the operations performed by the position detector 20 and the control panel 11 during normal operation.

[0036] In step S1, the position detection device 20 determines whether or not any of the multiple detectors 23 has detected pressure. At this time, when the position detection device 20 receives a signal from a detector 23, it determines that the detector 23 has detected pressure.

[0037] If it is determined in step S1 that the detector 23 has not detected pressure, the operation of step S1 is repeated.

[0038] If it is determined in step S1 that the detector 23 has detected pressure, the operation of step S2 is performed. In step S2, the position detection device 20 identifies the position of the detector 23 that detected the pressure, and detects the position of the car 8. The position detection device 20 transmits the position information of the car 8 to the control panel 11. The control panel 11 determines the current state of the car 8 based on the position information from the position detection device 20. Specifically, the control panel 11 determines whether the car 8 has passed through any floor, whether the car 8 has landed on any floor, whether the car 8 has reached the upper limit position in the hoistway 2, whether the car 8 has reached the lower limit position in the hoistway 2, or the like.

[0039] Thereafter, the operation of step S3 is performed. In step S3, the control panel 11 controls the position of the car 8 based on the state of the car 8 determined in step S2.

[0040] Thereafter, the operations from step S1 onwards are repeated.

[0041] Next, the control performed in the elevator device 1 will be described with reference to FIG. FIG. 6 is a flowchart for illustrating an overview of an abnormality diagnosis operation of the elevator system in the first embodiment.

[0042] As shown in FIG. 6, in step S11, the controller 22 determines whether any of the multiple detectors 23 detects pressure.

[0043] If it is not determined in step S11 that the detector 23 has detected pressure, the operation of step S11 is repeated.

[0044] If it is determined in step S11 that the detector 23 has detected pressure, the operation of step S12 is performed. In step S12, the controller 22 calculates an appropriate range for the pressure value indicated by the signal based on the accumulated information. The controller 22 determines whether the pressure value of the signal received in step S11 is within the appropriate range.

[0045] If it is determined in step S12 that the pressure value is within the range of appropriate values, the operation of step S13 is performed. In step S13, the controller 22 stores the information of the signal received in step S11 in the storage unit. Thereafter, the controller 22 repeats the operations from step S11 onward.

[0046] If it is determined in step S12 that the pressure value is not within the range of appropriate values, the operation of step S14 is performed. In step S14, the controller 22 calculates an abnormal value of the pressure value based on the accumulated information. Based on the accumulated information and the calculated abnormal value and pressure value, the controller 22 determines whether the pressure value of the signal from the detector 23 that emitted the signal has approached an abnormal value compared to the pressure value previously received from the detector 23.

[0047] If it is determined in step S14 that the value is approaching an abnormal value, the operation of step S15 is performed. In step S15, the controller 22 notifies the management center of a replacement instruction. Specifically, the controller 22 notifies a device provided in the management center via the monitoring device 12 of information indicating an instruction to replace the detector 23.

[0048] If it is not determined in step S14 that the pressure value is approaching the abnormal value, or if the operation of step S15 is performed, the operation of step S16 is performed. In step S16, the controller 22 determines whether or not the pressure value indicated by the signal received in step S11 is in an abnormal range below the abnormal value. Specifically, if the abnormal value indicates the upper limit of the pressure value, the controller 22 determines whether or not the pressure value has exceeded the abnormal value. If the abnormal value indicates the lower limit of the pressure value, the controller 22 determines whether or not the pressure value has fallen below the abnormal value.

[0049] If it is determined in step S16 that the pressure value is not within the abnormal range, the operations from step S13 onwards are carried out.

[0050] If it is determined in step S16 that the pressure value is within the abnormal range, the operation of step S17 is performed. In step S17, the controller 22 detects the abnormality. The controller 22 transmits a command to the control panel 11 to stop the car 8. The controller 22 notifies the management center by transmitting information indicating that the abnormality has been detected via the monitoring device 12 to a device provided in the management center.

[0051] Thereafter, the controller 22 performs the operations from step S13 onwards.

[0052] According to the first embodiment described above, the elevator device 1 includes the car 8, the guide rail 5, the guide shoe 10 as a guide body, and the position detection device 20. The position detection device 20 includes a detector 23 and a controller 22. The detector 23 is provided at a position where it contacts the guide shoe 10. For example, in the past, a detection plate was provided so as to protrude into the hoistway in order to detect the position of the car. Also, position detection devices are provided at positions such as the upper limit position and the lower limit position in the hoistway. In this case, a cam for pushing these position detection devices is provided on the car. These position detection devices are provided so as to protrude toward the car in the horizontal projection plane of the hoistway, or protrude from the car toward the wall side of the hoistway. On the other hand, each device provided on the car needs to be arranged so as not to interfere with the position detection device. On the other hand, in the elevator device 1 of the first embodiment, these position detection devices are not necessary. The detection unit 21 of the first embodiment is provided near the guide rail 5. Generally, there is little equipment provided between the guide rail 5 and the guide shoe 10. This can ease the constraints on the layout of the equipment in the horizontal projection plane of the elevator shaft. Since this constraint can be eased, the horizontal cross-sectional area of ​​the elevator shaft can be reduced.

[0053] Furthermore, conventional devices for position detection have a large number of parts. According to the elevator device 1 of the first embodiment, it is possible to reduce costs such as time, money, and manpower required for tasks such as installing devices for position detection, adjusting the positions of the devices, and maintaining the devices.

[0054] The position detection device 20 also includes a holder 25. The holder 25 holds the position of the detector 23 on the surface of the guide rail 5. The holder 25 is provided so as to be detachable from the guide rail 5. This makes it easy to perform installation and replacement of the detection unit 21.

[0055] Furthermore, the position detection device 20 judges whether or not the detector 23 should be replaced based on the accumulated information and the signal from the detector 23. When the position detection device 20 judges that the detector 23 should be replaced, it notifies the management center of that fact. Specifically, the position detection device 20 notifies the management center of the judgment that the detector 23 should be replaced. This makes it possible to discover a failure of the detection unit 21 at an early stage. Alternatively, the detection unit 21 can be replaced before it breaks down.

[0056] Furthermore, the guide shoe 10, which is a guide body, includes a guide portion 10a, which is a first guide portion, and a pressing portion 10b, which is a first pressing portion. Therefore, the guide shoe 10 can apply pressure to the detector 23 by the pressing portion 10b while guiding the car 8 by the guide portion 10a. Furthermore, vibrations that occur when the guide shoe 10 and the detector 23 come into contact can be suppressed more effectively than when the pressing portion 10b is not provided. This is because the guide shoe 10 can be prevented from riding up onto the detector 23.

[0057] The detector 23 may be bonded to the guide rail 5 by a bonding agent such as an adhesive or a pressure sensitive adhesive. In this case, the holder 25 does not need to be provided.

[0058] The distance between the guide shoe 10 and the head 5b on the side of the guide rail 5 may be set so that the detector 23 can come into contact with the guide shoe 10.

[0059] The position detector 20 may be provided to detect the position of the counterweight 9 .

[0060] Next, a modification of the first embodiment will be described with reference to FIGS. Fig. 7 is a horizontal cross-sectional view of a main part of an elevator apparatus according to a modification of embodiment 1. Fig. 8 is an enlarged horizontal cross-sectional view of a main part of an elevator apparatus according to a modification of embodiment 1.

[0061] As shown in Fig. 7, in a modification of the first embodiment, the car 8 is provided with a plurality of roller guide units 30 as a plurality of guide bodies. Four roller guide units 30 are provided in the car 8. Fig. 7 shows one of the four roller guide units 30. The roller guide unit 30 comes into contact with the guide rail 5 to guide the car 8 relative to the guide rail 5.

[0062] Each of the four roller guide units 30 includes roller guides 31 and 32 and a detection roller guide 33 .

[0063] The roller guides 31 and 32 have the same configuration. The roller guides 31 and 32 have conical rollers 31a and 32a, respectively. The roller guides 31 and 32 have first guide portions 31b and 32b on the outer periphery of the rollers 31a and 32a, respectively. The roller guides 31 and 32 press the rollers 31a and 32a against the guide rail 5, thereby bringing the first guide portions 31b and 32b into contact with the guide rail 5. In this manner, the roller guides 31 and 32 guide the car 8 relative to the guide rail 5.

[0064] The detection roller guide 33 faces the first surface 5c of the guide rail 5. The detection roller guide 33 includes a disk-shaped roller 33a. The detection roller guide 33 includes a first guide portion 33b on the outer periphery of the roller 33a. The first guide portion 33b faces the first surface 5c. The detection roller guide 33 includes a first pressing portion 33c on the outer periphery of the roller 33a. The first pressing portion 33c faces the first surface 5c. The first pressing portion 33c is a notch provided on the outer periphery of the roller 33a over the entire circumference. That is, the first pressing portion 33c is recessed with respect to the first guide portion 33b over the entire circumference of the roller 33a. For example, the distance between the bottom surface of the first pressing portion 33c and the bottom surface of the first guide portion 33b is equal to the thickness of the detector 23. As shown in FIG. 7, when the car 8 is in a position corresponding to the detector 23, a part of the first pressing portion 33c faces the detector 23.

[0065] 8 shows the main parts when the car 8 has passed the position corresponding to the detector 23. The detection roller guide 33 presses the roller 33a against the guide rail 5. In this state, a part of the first guiding portion 33b contacts the first surface 5c of the guide rail 5. A part of the bottom surface of the first pressing portion 33c contacts the detector 23. At this time, the detector 23 receives pressure from the first pressing portion 33c while being sandwiched between the guide rail 5 and the first pressing portion 33c.

[0066] In the modification of the first embodiment described above, the elevator device 1 includes a roller guide unit 30 as a guide body instead of the guide shoe 10. In this case, as in the case of the guide shoe 10, the position of the car 8 can be detected by the position detection device 20. At this time, the roller guide unit 30 presses the roller 33a against the guide rail 5. This improves the detection accuracy of the detector 23.

[0067] Next, an example of hardware constituting the controller 22 will be described with reference to FIG. FIG. 9 is a hardware configuration diagram of a controller of the elevator apparatus according to the first embodiment.

[0068] Each function of the controller 22 may be realized by a processing circuit. For example, the processing circuit may include at least one processor 100a and at least one memory 100b. For example, the processing circuit may include at least one dedicated hardware 200.

[0069] When the processing circuit includes at least one processor 100a and at least one memory 100b, each function of the controller 22 is realized by software, firmware, or a combination of software and firmware. At least one of the software and firmware is written as a program. At least one of the software and firmware is stored in the at least one memory 100b. The at least one processor 100a realizes each function of the controller 22 by reading and executing the program stored in the at least one memory 100b. The at least one processor 100a is also called a central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, or DSP. For example, the at least one memory 100b is a non-volatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, or an EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD, or the like.

[0070] When the processing circuit includes at least one dedicated hardware 200, the processing circuit is realized, for example, by a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the controller 22 is realized by a processing circuit. For example, each function of the controller 22 is realized collectively by a processing circuit.

[0071] Some of the functions of the controller 22 may be realized by dedicated hardware 200, and the remaining parts may be realized by software or firmware. For example, the function of storing information on received signals may be realized by a processing circuit as the dedicated hardware 200, and functions other than the function of storing information on received signals may be realized by at least one processor 100a reading and executing a program stored in at least one memory 100b.

[0072] Thus, the processing circuitry implements the functions of the controller 22 in hardware 200, software, firmware, or a combination thereof.

[0073] Although not shown, each function of the control panel 11 is also realized by a processing circuit equivalent to the processing circuit that realizes each function of the controller 22.

[0074] Embodiment 2 Fig. 10 is an enlarged horizontal cross-sectional view of a main part of an elevator device in accordance with embodiment 2. Note that the same reference numerals are used to designate parts that are the same as or correspond to parts in embodiment 1. Explanation of these parts will be omitted.

[0075] In the second embodiment, the guide rail 5 includes a second guide portion 5d and a second pressing portion 5e on the first surface 5c. The second guide portion 5d is the same as the surface of the first surface 5c in the first embodiment.

[0076] The second pressing portion 5e is a notched groove provided at the position of the detector 23. That is, the second pressing portion 5e is recessed with respect to the second guide portion 5d. The distance between the bottom surface of the second pressing portion 5e and the surface of the second guide portion 5d is equal to the thickness of the detector 23. Although not shown, a plurality of second pressing portions 5e are provided at the positions of a plurality of detectors 23.

[0077] The detector 23 is provided inside the second pressing portion 5e. For example, the detector 23 is attached to the bottom surface of the second pressing portion 5e with an adhesive. At this time, the signal line 24 may be passed through the inside of the guide rail 5.

[0078] 10 shows the main part when the car 8 has passed the position corresponding to the detector 23. In this state, a part of the second guide portion 5d contacts the guide shoe 10. The detector 23 and the guide shoe 10 come into contact. At this time, the detector 23 is sandwiched between the second pressing portion 5e of the guide rail 5 and the guide shoe 10 and receives pressure from the guide shoe 10.

[0079] According to the above-described second embodiment, the guide rail 5 has the second guide portion 5d and the second pressing portion 5e. The detector 23 is provided inside the second pressing portion 5e. Therefore, the guide shoe 10 can apply pressure to the detector 23 while guiding the car 8 by contacting the second guide portion 5d.

[0080] The position detection device 20 in the first and second embodiments does not have to be provided inside the control panel 11. Moreover, the position detection device 20 may be connected to a safety device that monitors the speed of the car 8, instead of the control panel 11, and may be provided inside the safety device. In this case, the safety device may detect the position of the car 8 based on information from the position detection device 20.

[0081] In the second embodiment, the guide shoe 10 may have a pressing portion 10b. In this case, the distance between the pressing portion 10b and the second pressing portion 5e does not have to be equal to the distance between the detector 23 and the pressing portion 10b.
