[0001] The present disclosure relates to cleaning of a linear scale in an elevator system in which the values ​​of a linear scale installed along the entire length of an elevator shaft are read by a reading device in the elevator car, position information is obtained, and the operation of the elevator car is controlled. [Background technology]

[0002] As an elevator device using a linear scale, there is a technology such as that disclosed in Patent Document 1, but cleaning of the linear scale is not taken into consideration. Furthermore, although the object to be cleaned is different from the linear scale, a technique has been disclosed for cleaning ropes arranged in an elevator shaft, in which a cleaning solution is sprayed onto the ropes as the elevator car moves from the top floor to the bottom floor (for example, Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6167885 [Patent Document 2] Japanese Patent Application Laid-Open No. 2002-362852 Summary of the Invention [Problem to be solved by the invention]

[0004] When attempting to apply rope cleaning as in Patent Document 2 to a linear scale installed along the entire length of an elevator shaft, there is a problem in that cleaning the linear scale requires a lot of work time and a large amount of cleaning liquid to clean the entire length of the elevator shaft.

[0005] The present disclosure has been made to solve the above-mentioned problems, and aims to provide an elevator system that does not clean the entire length of the hoistway, but rather identifies areas that cannot be read due to dust adhering to the linear scale, and cleans them in a short time using the minimum amount of cleaning liquid required. [Means for solving the problem]

[0006] The elevator device according to the present disclosure comprises a linear scale provided along the path of movement of a car ascending and descending within the elevator shaft and having position information within the elevator shaft, a reading means provided in the car and reading the position information from the linear scale, and an elevator control means for controlling the operation of the car based on the position information read by the reading means, and is characterized by comprising a water-spraying means for spraying cleaning liquid onto the linear scale, and a water-spraying control means for causing the water-spraying means to spray water based on the position information read by the reading means. [Effects of the Invention]

[0007] According to the present disclosure, the elevator device has the advantage of being able to identify areas that could not be read due to dust adhering to the linear scale, rather than cleaning the entire length of the elevator shaft, and clean them in a short time using the minimum amount of cleaning liquid required.

[0009] Embodiment 1 An overall configuration diagram of an elevator in the first embodiment will be described with reference to Fig. 1. Fig. 1 is an overall configuration diagram of an elevator in which an elevator device is installed.

[0010] The elevator comprises a car 1, a main rope 2, a counterweight 3, a hoist 6, and a control panel 7. One end of a main rope 2 is connected to the upper end of the car 1, and a counterweight 3 is connected to the other end of the main rope 2. A hoist 6 is installed in the middle of the main rope 2 so that the car 1 and the counterweight 3 rise and fall in opposite directions. A linear scale 11 having position information within the elevator shaft (not shown) along the path of movement of the elevator car 1 is installed in the elevator shaft along which the elevator car 1 moves up and down.

[0011] The elevator car 1 is equipped with a reading means 12, an on-car device 13, and a cleaning means 16. A reading means 12 installed in the elevator car 1 reads the position information from the linear scale 11 and transmits it to an on-car device 13 . The on-car device 13 transmits the position information of the linear scale 11 read by the reading means 12 to the control panel 7 via the control cable 8. The control panel 7 drives the hoist 6 based on the position information of the linear scale 11 read by the reading means 12, and controls the lifting and lowering of the car 1.

[0012] The cleaning means 16 installed in the car 1 is connected to the on-car equipment 13 and transmits and receives signals to and from the control panel 7 via the on-car equipment 13. The cleaning means 16 is a means for cleaning the linear scale 11 and the reading means 12 to remove dirt such as oil and dust.

[0013] The reading means 12, on-car equipment 13, and cleaning means 16 installed in the elevator car 1 are divided into functional blocks to explain their respective functions, but they may be configured as a single unit or may be separate. For example, the cleaning means 16 may be provided in the on-car equipment 13. The integration of the functional blocks reduces the labor required for wiring the car 1 and reduces the risk of disconnecting the wiring during maintenance work on the car 1.

[0014] A block diagram of the elevator apparatus according to the first embodiment will be described with reference to Fig. 2. Fig. 2 is a block diagram of the elevator apparatus according to the first embodiment.

[0015] First, a block diagram of the control panel 7 will be described. The control panel 7 includes a control panel control unit 21, a control panel communication I / F unit 22, a control panel storage unit 23, and a drive unit 24. The control panel control unit 21 of the control panel 7 acquires the position information of the linear scale 11 acquired by the reading means 12 via the on-car device 13 through the control panel communication I / F unit 22 . Furthermore, the control panel control unit 21 transmits and receives signals to and from the cleaning means 16 via the on-car equipment 13 through the control panel communication I / F unit 22 .

[0016] The control panel storage unit 23 of the control panel 7 stores the control program of the control panel control unit 21, control calculation data, and position information of the linear scale 11. The control panel storage unit 23 may be any means capable of storing data and reading out the stored data, such as SRAM (Static Random Access Memory) or EEPROM (Electrically Erasable Programmable Read Only Memory).

[0017] The control panel control unit 21 sends a drive command to the drive unit 24 based on the position information of the linear scale 11 to drive the hoisting machine 8. Here, the control panel control unit 21 is defined as elevator control means.

[0018] Next, a block diagram of the cleaning means 16 installed in the car 1 will be described. The cleaning means 16 installed in the car 1 includes a cleaning means control unit 26, a cleaning means communication I / F unit 27, a cleaning means storage unit 28, and a cleaning unit 29. The cleaning means control unit 26 of the cleaning means 16 transmits and receives signals to and from the control panel 7 via the on-car equipment 13 through the cleaning means communication I / F unit 27 .

[0019] The cleaning means storage unit 28 of the cleaning means 16 stores the control program for the cleaning means control unit 26 and saves control calculation data. Cleaning means storage unit 28 may be any means that can store data and read out the stored data, such as SRAM (Static Random Access Memory) or EEPROM (Electrically Erasable Programmable Read Only Memory).

[0020] The cleaning means control unit 26 of the cleaning means 16 activates and stops the cleaning unit 29. The cleaning unit 29 is provided with a cleaning liquid for cleaning dirt such as oil and dust adhering to the linear scale 11 and the reading means 12. The cleaning liquid may be any liquid that can remove dirt such as oil and dust and is highly volatile. Here, the cleaning means control unit 26 and the cleaning unit 29 are defined as the water discharge control unit and the water discharge unit, respectively.

[0021] The cleaning means control unit 26 receives a cleaning operation command signal from the control panel 7 via the on-car equipment 13, and causes the cleaning unit 29 to clean the linear scale 11 and the reading means 12. The cleaning operation command signal sent from the control panel 7 to the cleaning means 16 may be a signal that includes the strength of the spray of cleaning liquid. For example, the cleaning operation command signal may include a "cleaning operation command" and "strong, medium, weak." When the cleaning operation command signal includes "strong," the cleaning unit 29 sprays cleaning liquid strongly onto the linear scale 11, and when the cleaning operation command signal includes "weak," the cleaning unit 29 sprays cleaning liquid weakly onto the linear scale 11 and the reading means 12.

[0022] By making the cleaning operation command signal a signal including the strength of the cleaning liquid, when the position information of the linear scale 11 cannot be read over a wide range, the cleaning liquid is released strongly, and when the position information of the linear scale 11 cannot be read over a small range, the cleaning liquid is released weakly. The strength of the cleaning liquid has the effect of being able to clean dirt such as oil and dust adhering to the linear scale 11 and the reading means 12 while reducing the amount of cleaning liquid used.

[0023] A flowchart for storing position information of the control panel of the elevator apparatus according to embodiment 1 will be described with reference to Figures 3 and 4. Figure 3 is a flowchart for storing position information of the control panel of the elevator apparatus according to embodiment 1. Figure 4 shows the result of storing position information of the control panel of the elevator apparatus according to embodiment 1.

[0024] In step S1 , the control panel control unit 21 of the control panel 7 acquires the position information of the linear scale 11 read by the reading means 12 . In step S2, the control panel control unit 21 determines whether the position information of the linear scale 11 read by the reading means 12 has been acquired. If the control panel control unit 21 has been able to acquire the position information of the linear scale 11 read by the reading means 12, the control panel control unit 21 proceeds to step S3 (YES in step S2). On the other hand, if the position information of the linear scale 11 cannot be acquired, the process ends. In step S3, the control panel control unit 21 stores the position information of the linear scale 11 in the control panel storage unit 23, and then the process ends.

[0025] In FIG. 4, the control panel storage unit 23 stores the position information of the linear scale 11 and the results of acquiring that position information. The position information of the linear scale 11 has been acquired for positions from "1000" to "1007" and positions from "1013" to "1019." On the other hand, the position from beyond "1007" to just before "1013" has not been acquired. In other words, from the position beyond "1007" to the position just before "1013", the position information on the linear scale 11 is contaminated with oil, dust, etc. and cannot be read.

[0026] A flowchart of the elevator apparatus according to the first embodiment will be described with reference to Fig. 5. Fig. 5 is a flowchart of the elevator apparatus according to the first embodiment.

[0027] In step S11, the control panel control unit 21 of the control panel 7 acquires the position information stored in the control panel storage unit 23. In step S12, the control panel control unit 21 determines whether or not there is a location (range) in the control panel storage unit 23 for which no position information is stored. If there is a location for which position information is not stored in the control panel storage unit 23, the control panel control unit 21 proceeds to step S13 (YES in step S12). On the other hand, if there is no location for which the position information is not stored in the control panel storage unit 23, the process ends (NO in step S12).

[0028] Specifically, in FIG. 4, the location (range) where no location information is stored is the area from a position beyond "1007" to a position just before "1013." The control panel control unit 21 reads the position information of the linear scale 11 one step at a time, such as "1000," "1001," and "1002," but is unable to read the position information from the position beyond "1007" to the position just before "1013."

[0029] In step S13, the control panel control unit 21 sends a drive command to the drive unit 24 to drive the hoisting machine 8, and moves the car 1 to a position immediately before a location for which position information is not stored. 4, for example, if the position of the car 1 before the start of the flow process is at position "1002" on the linear scale 11, the control panel control unit 21 moves the car 1 to position "1007" on the linear scale 11. Also, if the position of the car 1 before the start of the flow process is at position "1017" on the linear scale 11, the control panel control unit 21 moves the car 1 to position "1013" on the linear scale 11.

[0030] In step S14, the control panel control unit 21 determines whether or not the car 1 has moved to a position immediately before a location for which position information is not stored. If the car 1 has moved to a position immediately before a location for which no position information is stored, the control panel control unit 21 proceeds to step S15 (YES in step S14). On the other hand, if the car 1 has not moved to a position immediately before the location for which the position information is not stored, the process proceeds to step S13 (NO in step S14).

[0031] In step S15, the control panel control unit 21 transmits a cleaning operation command signal to the cleaning unit control unit 21 of the cleaning unit 16, causing the cleaning unit 29 to clean the linear scale 11 and the reading unit 12. In step S16, the control panel control unit 21 determines whether or not the car 1 has moved to the location for which the position information is stored. If the car 1 has moved to the location for which the position information is stored, the control panel control unit 21 proceeds to step S17 (YES in step S16). On the other hand, if the car 1 has not moved to the location for which the position information is stored, the process proceeds to step S15 (NO in step S16).

[0032] 4, for example, when the position of the car 1 before the start of the flow process is at position "1002," the control panel control unit 21 determines whether the car 1 has moved from position "1007" to position "1013" on the linear scale 11. Also, when the position of the car 1 before the start of the flow process is at position "1017" on the linear scale 11, the control panel control unit 21 determines whether the car 1 has moved from position "1013" to position "1007" on the linear scale 11.

[0033] In step S17, the control panel control unit 21 controls the cleaning means control unit 21 of the cleaning means 16. A cleaning operation command signal is sent to stop the cleaning unit 29 from cleaning the linear scale 11 and the reading means 12 . 4, for example, if the position of the car 1 before the start of the flow process is at position "1002," the control panel control unit 21 stops cleaning when the car 1 is moved to position "1013" on the linear scale 11. Also, if the position of the car 1 before the start of the flow process is at position "1017" on the linear scale 11, the control panel control unit 21 stops cleaning when the car 1 is moved to position "1007" on the linear scale 11.

[0034] In step S18, the control panel control unit 21 acquires the position information of the linear scale 11 read by the reading means 12 while moving the car 1 within the range of position information for which the linear scale 11 has been cleaned.

[0035] In step S19, the control panel control unit 21 determines again whether or not there is a location (range) for which no position information is stored. If there is a location for which position information is not stored in the control panel storage unit 23, the control panel control unit 21 proceeds to step S11 (YES in step S19). On the other hand, if there is no location for which the position information is not stored in the control panel storage unit 23, the process ends (NO in step S19).

[0036] As described above, the elevator device according to the first embodiment has the advantage of being able to identify areas that could not be read due to dust adhering to the linear scale, rather than cleaning the entire length of the elevator shaft, and to clean them in a short time using the minimum amount of cleaning liquid required.

[0037] Embodiment 2 An overall configuration diagram of an elevator in the second embodiment will be described with reference to Fig. 6. Fig. 6 is an overall configuration diagram of an elevator in which an elevator device is installed. In the description of FIG. 6, the parts corresponding to the overall configuration diagram of the elevator in the first embodiment are given the same reference numerals as in FIG. 1, and the description thereof will be omitted.

[0038] In the elevator car 1, a drying unit 31 is installed near the reading means 12. The drying unit 31 facilitates the evaporation of the cleaning liquid from the cleaning unit 29, which will be described later.

[0039] An external view of the drying unit of the elevator apparatus in the second embodiment will be described with reference to Fig. 7. Fig. 7 is an external view of the drying unit of the elevator apparatus.

[0040] 7(1) shows a side view of the drying unit 31 installed near the cleaning means 16. In FIG. The drying unit 31 is installed at a position where the linear scale 11 and the reading means 12 can be cleaned by a nozzle, which will be described later.

[0041] The perspective view of FIG. 7(2) shows a perspective view of the drying unit 31. The drying section 31 includes an air collecting means 36, a first nozzle 37, and a second nozzle 38. The air collecting means 36 of the drying section 31 is configured to collect air into the air collecting means 36 as the car 1 rises, and the collected air is blown out from the first nozzle 37 and the second nozzle 38. The first nozzle 37 and the second nozzle 38 of the drying unit 31 are configured to blow out the air collected by the air collecting means 36 as the car 1 rises, to the linear scale 11 and the reading means 12, respectively.

[0042] Furthermore, the air collecting means 36 of the drying unit 31 is installed so as to collect air when the car 1 rises, but the air collecting means 36 may be installed facing downward so as to collect air when the car 1 falls. Furthermore, the drying unit 31 may be installed in two locations, and air may be collected when the car 1 rises and when it falls, respectively.

[0043] As described above, the elevator system according to the second embodiment has the advantage that the cleaning liquid discharged onto the linear scale and the reading means can be quickly dried by the drying section, and the position information on the linear scale can be quickly read.

[0044] The elevator system of the present disclosure configured as described above is an elevator system comprising: a linear scale 11 provided along the movement path of the car 1 ascending and descending within the elevator shaft and having position information within the elevator shaft; a reading means 12 provided in the car 1 and reading the position information from the linear scale 11; and an elevator control means for controlling the operation of the car 1 based on the position information read by the reading means 12, and is characterized by comprising a water-discharging means for discharging cleaning liquid onto the linear scale 11; and a water-discharging control means for causing the water-discharging means to discharge water based on the position information read by the reading means 12.

[0045] This has the effect of enabling the user to identify areas that could not be read due to dust adhering to the linear scale, rather than cleaning the entire length of the elevator shaft, and clean them in a short time using the minimum amount of cleaning liquid required.

[0046] The elevator device of the present disclosure is also characterized by comprising an air collection means 36 that collects the airflow generated when the car 1 rises and falls, a first nozzle 37 that blows the airflow collected by the air collection means 36 onto the linear scale 11, and a second nozzle 38 that blows the airflow collected by the air collection means 36 onto the reading means 12.

[0047] This allows the elevator device to quickly dry the cleaning liquid discharged onto the linear scale and the reading means by the drying section, thereby enabling the position information on the linear scale to be read quickly. [Explanation of symbols]
