The elevator monitoring panel 17 has an elevator pull-back switch 18 for pulling back a car of a designated car among the car 11a, 11b, etc., and a cleaning operation for each car 11a, 11b, car of each car. A cleaning operation indicator lamp 19 or the like is provided for indicating that it is inside.
[0021]
FIG. 2 is a diagram showing a configuration of an elevator car in the embodiment. In addition, although the structure as the car 11a is shown here for convenience, it is the same structure also about the other cars 11b.
[0022]
As shown in FIG. 2, a glass window 12 is provided in a surface of the elevator car 11 a that faces the glass shaft 10 a of the hoistway 10, and a car operation panel 21 is provided in the vicinity of the glass window 12. ing. The car operation panel 21 is different from a normal operation panel installed in the vicinity of a car door (not shown), and an elevator maintenance person passes outside the car 11a (that is, the hoistway 10 of the hoistway 10) through the glass window 12 during the cleaning operation. This is used when the cleaning work is performed while looking at the glass shaft 10a).
[0023]
The car operation panel 21 includes a destination operation button 22 on each floor, a cleaning operation switch 23 for setting a cleaning operation mode, an UP travel switch 24 for traveling the car 11a in the up direction, and a car.

[0024]
Further, on the car 11a, a driving operation unit 26 for instructing the UP / DOWN traveling of the car 11a during the cleaning operation is provided in the same manner as described above. The functions of the UP travel switch 27 and the DOWN travel switch 28 provided in the driving operation unit 26 are the same as the UP travel switch 24 and the DOWN travel switch 25 provided in the car operation panel 21 in the car 11a.
[0025]
Next, the operation | movement at the time of the cleaning driving | operation in the elevator of the said structure is demonstrated.
[0026]
FIG. 3 is a flowchart showing the operation during the elevator cleaning operation in the embodiment.
[0027]
Now, a case where a certain car 11a is used and the glass shaft 10a of the hoistway 10 surrounding the car 11a is cleaned will be described.
[0028]
First, the building manager selects the car 11a existing in the hoistway 10 to be cleaned from the elevator monitoring panel 17, and operates the elevator pull-back switch 18. When the elevator pull-back switch 18 is turned on (Yes in step A11), the pull-back operation is executed by the operation control unit 15a, and the car 11a is automatically operated up to a specific floor (for example, the first floor). Wait until the maintenance person gets in, with the door open (step A12).
[0029]
Here, when the elevator pull-back switch 18 is operated, the car 11a is run exclusively for cleaning. Therefore, the already registered landing call (registered by operating the call button installed at the landing on each floor) If there is a call signal), cancel at that point. In this case, the other car that is not designated for the pull-back operation responds to the canceled landing call. In addition, for registered car calls (call signals registered by operating the destination floor specification button installed in the car), the car will be moved to a specific floor while responding to the car call at that time without canceling. . After the car 11a has landed on the specific floor, the car call cannot be registered while the car 11a is open and waiting.
[0030]
Next, a maintenance person gets into the car 11a that has landed on the specific floor by the pull-back operation, and operates the cleaning operation switch 23 of the car operation panel 21 installed in the car 11a (step A13). The cleaning operation mode is set by operating the cleaning operation switch 23, the cleaning operation indicator light 19 of the car 11a on the elevator monitoring panel 17 is turned on, and it is displayed that the car 11a is in the cleaning operation (step). A14).
[0031]
When the cleaning operation mode is set, the operation control unit 15a notifies the operation control unit 15b via the group management control unit 16. Receiving this notification, the operation control unit 15b stops the operation of the car 11b adjacent to the car 11a (step A15). At this time, the adjacent unit does not stop operation immediately, but if there is a registered call, it will be stopped after responding to all calls.
[0032]
After confirming that the car 11b, which is the adjacent car, has been suspended, the cleaning person gets on the car 11a together with the elevator maintenance staff, and ascends and descends with the cleaning tool 31 as shown in FIG. Cleaning of the glass shaft 10a of the path 10 is started. At that time, when the maintenance worker who has climbed the car 11a together with the cleaner operates the UP travel switch 27 and the DOWN travel switch 28 of the driving operation unit 26 provided on the car 11a (Yes in Step A16), The car 11a travels in the UP direction or the DOWN direction from the specific floor at an ultra-low speed with the travel speed regulated within a predetermined speed (step A17). Thereby, the cleaner can efficiently clean the glass shaft 10a up and down from the specific floor while riding on the car 11a.
[0033]
After cleaning, when the cleaning person gets down from the car 11a together with the maintenance person and turns off the cleaning operation switch 23 in the car 11a (Yes in Step A18), the operation cleaning mode is canceled, and the operation control unit The cleaning operation indicator lamp 19 is turned off by being transmitted to the elevator monitoring panel 17 via 15a (step A19), and the car 11a returns to the normal operation mode (step A20). Further, the fact that the operation cleaning mode has been canceled is also notified to the operation control unit 15b via the group management control unit 16, and the operation of the car 11b is resumed (step A21).
[0034]
In this way, when the cleaning person gets on the car 11a and cleans the glass shaft 10a of the hoistway 10, the operation of the other adjacent car 11b is suspended, so that the cleaning person can remove the car 11a. Cleaning work can be performed safely even above. In the state where the cleaning operation mode is set, the traveling speed of the car 11a by the switch operation is restricted. Therefore, when the car 11a is moved while the car 11a is being moved, the car 11a suddenly moves due to an operation error, for example. It is possible to prevent the danger of moving quickly and being shaken off.
[0035]
In the above embodiment, as shown in FIG. 4, the cleaning staff holds the cleaning tool 31 on the car 11 a and cleans the glass shaft 10 a of the hoistway 10, but as shown in FIG. 5. It is also possible to perform the cleaning work by the method.
[0036]
That is, as shown in FIG. 5, a tool mounting portion 32 for detachably mounting the cleaning tool 31 is installed on the car 11a. The specific configuration of the tool mounting portion 32 is not particularly limited. For example, the handle portion of the cleaning tool 31 is fitted into a mounting bracket fixed at a predetermined position on the car 11a. It has become.
[0037]
In the car 11 a provided with such a tool mounting portion 32, the cleaning staff only has to climb on the car 11 a and attach the cleaning tool 31 to the tool mounting portion 32. Thereafter, if the car 11a is caused to travel by operating the UP travel switch 24 and the DOWN travel switch 25 of the car operation panel 21 installed in the car 11a, the hoistway is provided even if there is no cleaner on the car 11a. Ten glass shafts 10a can be automatically cleaned.
[0038]
Further, in the car 11a, the car operation panel 21 is installed not on the door 33 side but on the opposite side, that is, on the glass shaft 10a side, which is the cleaning surface of the hoistway 10, as shown in FIG. A glass window 12 is disposed in the vicinity of the car operation panel 21. In this case, since there is usually an operation panel on the door 33 side in the car 11a, the operator (maintenance staff or cleaning staff) must operate the operation panel while turning back, as in this embodiment. Since the car operation panel 21 dedicated for cleaning is installed on the glass shaft 10 a side, the car operation panel 21 is operated to clean the car 11 a while operating the car 11 a while checking the dirt condition of the glass shaft 10 a through the glass window 12. Work can be done.
[0039]
Moreover, although the said embodiment demonstrated the case where the one car 11a was cleaning-operated, it is also possible to drive the other car 11b ... simultaneously and to perform a cleaning operation. The operation at this time is shown in FIG.
[0040]
FIG. 6 is a flowchart showing an operation during an elevator cleaning operation according to another embodiment of the present invention.
[0041]
First, the building manager selects the cars 11a, 11b... Existing in the hoistway 10 on the elevator monitoring panel 17, and operates the elevator pull-back switch 18. When the elevator pull-back switch 18 is turned on (Yes in step B11), the pull-back operation is performed by the operation control units 15a, 15b, and each of the passenger cars 11a, 11b is automatically operated up to a specific floor (for example, the first floor). Then, it waits in a state where the door is opened until the cleaner and the elevator maintenance worker get on the specific floor (step B12).
[0042]
In this case, when the elevator pull-back switch 18 is operated, all the cars 11a, 11b,... Are run exclusively for cleaning, and therefore the cleaning operation is performed in advance so that the landing call and the car call are not registered on the way. It is preferable to notify the users in the platform or the car to the effect that
[0043]
When all of the cars 11a, 11b... Land on a specific floor (Yes in Step B13), a maintenance person gets into a predetermined car 11a, and a car operation panel installed in the car 11a. 21 cleaning operation switch 23 is operated (step B14). The cleaning operation mode is set by operating the cleaning operation switch 23, the cleaning operation indicator lights 19 of the cars 11a, 11b,... On the elevator monitoring panel 17 are turned on, and the cars 11a, 11b,. Is displayed (step B15).
[0044]
A cleaning person gets on each car 11a, 11b ... with the maintenance staff of an elevator, and starts cleaning glass shaft 10a of hoistway 10 with cleaning tool 31, as shown in FIG. In this case, a cleaning person and a maintenance person get in every car 11a, 11b ....
[0045]
Here, in a predetermined car 11a among the cars 11a, 11b,..., When a maintenance person climbing on the car 11a operates the UP travel switch 27 and the DOWN travel switch 28 of the driving operation unit 26 (step). B16), with the traveling speeds of the cars 11a, 11b... Regulated within a predetermined speed, these cars 11a, 11b. (Step B17). Thereby, each cleaner can efficiently clean the glass shaft 10a up and down from the specific floor while riding on the cars 11a, 11b.
[0046]
After cleaning, when the cleaning person gets down from the car 11a together with the maintenance person and turns off the cleaning operation switch 23 in the car 11a (Yes in Step B18), the operation cleaning mode is canceled, and the operation control unit .. Is transmitted to the elevator monitoring panel 17 via 15a and the cleaning operation indicator lights 19 of the respective cars 11a and 11b are turned off (step B19), and the cars 11a, 11b... Are returned to the normal operation mode (step B20). .
[0047]
As described above, the glass shaft 10a of the hoistway 10 can be cleaned more efficiently than when the cars are moved one by one by performing the cleaning operation in conjunction with the cars 11a, 11b. Moreover, since each of the cars 11a, 11b... Is interlocked, the adjacent car is in a different direction while the cleaner is cleaning the car 11a, 11b. The car will not run suddenly and can be cleaned safely.
[0048]
Further, even when the cleaning operation is performed by interlocking operation of each of the cars 11a, 11b, etc., as shown in FIG. 5, the cleaning tool 31 is attached to the tool mounting portion 32 installed on each of the cars 11a, 11b,. Is convenient because it is possible to automatically clean the glass shaft 10a of the hoistway 10 only by running the cars 11a, 11b... Up and down.
[0049]
In each of the above-described embodiments, the elevator for observation has been described as an example. However, the present invention is not limited to this, and can be applied to the case where the inside of a hoistway in a normal elevator that is not glass-coated is cleaned.
