In this case, even if the photoelectric post 14 is far from the skirt guard 12 due to the arrangement of the escalator 10, the foreign matter on the board 13 can be pushed out by blowing air from the column 15. In addition, even if it is a case where only the 1st air blower 17 is provided without providing the 2nd air blower 18, the foreign material on the boarding board 13 can be pushed out.

  FIG. 4 is a block configuration diagram showing the passenger conveyor entrance / exit cleaning device according to Embodiment 1 of the present invention. In FIG. 4, this passenger conveyor entrance cleaning device includes a photoelectric post 14, a first blower 17, a second blower 18, a camera 21, a rainwater sensor 22, a humidity sensor 23, and a control unit 30.

  Here, the control unit 30 is based on the detection result by the photoelectric post 14 indicating the operation state of the escalator 10, and the detection result by the camera 21, the rainwater sensor 22 and the humidity sensor 23 indicating the state of the foreign matter on the boarding board 13. The first blower 17 and the second blower 18 are driven.

  Hereinafter, conditions for the control unit 30 to start blowing from the first blower 17 and the second blower 18 will be specifically described. When the photoelectric post 14 detects that there is no passenger, the control unit 30 determines that the blowing can be started. Moreover, the control part 30 judges that ventilation is required when the foreign material on the boarding board 13 is detected by either the camera 21, the rainwater sensor 22, and the humidity sensor 23. FIG.

  That is, when it is detected that there is no passenger and a foreign object on the boarding board 13 is detected, the control unit 30 starts blowing by the first blower 17 and the second blower 18. At this time, the control part 30 performs the ventilation by the 1st air blower 17 after the ventilation by the 2nd air blower 18, and repeats this. Note that the control unit 30 increases the air volume or intermittently blows air from the second blower 18 when the foreign matter is not lost even by blowing by the first blower 17 and the second blower 18. You may blow intermittently.

  Further, the control unit 30 may drive the first blower 17 and the second blower 18 based only on the operating state of the escalator 10. In this case, the control unit 30 may drive the first blower 17 and the second blower 18 once after a predetermined time has elapsed after the photoelectric post 14 detects that no passenger is present, or periodically. Alternatively, the first blower 17 and the second blower 18 may be driven.

  Next, conditions for the control unit 30 to stop the blowing from the first blower 17 and the second blower 18 will be specifically described. First, when the photoelectric post 14 detects that a passenger is present, the control unit 30 stops blowing. Moreover, the control part 30 stops blowing, when the foreign material on the boarding board 13 is no longer detected from any of the camera 21, the rainwater sensor 22, and the humidity sensor 23.

  That is, the control part 30 stops the ventilation by the 1st air blower 17 and the 2nd air blower 18, when it detects that there exists a passenger or the foreign material on the boarding board 13 is no longer detected. Note that the control unit 30 may stop driving the first blower 17 and the second blower 18 based only on the operating state of the escalator 10. In this case, the control unit 30 stops the blowing when a predetermined time has elapsed from the start of blowing or when the number of times of blowing from the first blower 17 and the second blower 18 exceeds the predetermined number.

  FIG. 5 is a flowchart showing an operation of the passenger conveyor entrance / exit cleaning device according to Embodiment 1 of the present invention. Here, the case where the blowing is stopped according to the state of the foreign matter on the boarding board 13 after a predetermined time has elapsed from the start of blowing by the first blower 17 and the second blower 18 will be described as an example. It is assumed that no passengers are detected before stopping.

  First, the control unit 30 determines whether or not a passenger is detected by the photoelectric post 14 (step S1).

  If it is determined in step S1 that no passenger has been detected (that is, No), it is determined whether any foreign matter on the board 13 is detected by any of the camera 21, rainwater sensor 22, and humidity sensor 23. Determine (step S2).

  If it is determined in step S2 that a foreign object has been detected (that is, Yes), the control unit 30 blows air from the second blower 18 (step S3), and then blows air from the first blower 17. (Step S4).

  On the other hand, if it is determined in step S1 that a passenger has been detected (that is, Yes), or if it is determined in step S2 that no foreign object has been detected (that is, No), it is as shown in FIG. The process ends.

  Subsequently, the control unit 30 determines whether or not a predetermined time has elapsed since the start of air blowing (step S5).

  If it is determined in step S5 that the predetermined time has elapsed (that is, Yes), the control unit has detected a foreign object on the boarding board 13 by any one of the camera 21, the rainwater sensor 22, and the humidity sensor 23. It is determined whether or not (step S6).

  If it is determined in step S6 that no foreign matter has been detected (ie, No), the control unit 30 stops blowing air from the first blower 17 and the second blower 18 (step S7). The process of 5 is finished.

  On the other hand, if it is determined in step S5 that the predetermined time has not elapsed (that is, No), or if it is determined in step 6 that a foreign object has been detected (that is, Yes), the process proceeds to step 3. Transition.

As described above, according to the first embodiment, at the entrance / exit, the first blower that is provided at a position farther from the step than the skirt guard and blows air outside the entrance / exit board through the entrance / exit board is provided. It is driven when the operating state of the passenger conveyor satisfies a preset condition.
