I am doing it.

To measure the dirt on the moving handrail 1, JIS; Z
A colorimeter 17 designed based on -8722 is used, and the colorimeter 17 detects the color value of the object based on the detection value of the sensor 16. The sensor 16 has a sensitivity of a color matching function corresponding to the spectral power of the human eye, and measures the tristimulus values X, Y, Z of the color by the reflected light of the light applied to the measurement object. A photoelectric sensor is used. The colorimeter 17 is configured to calculate chromaticity from the tristimulus values measured by the sensor 16 and calculate hue and saturation. Further, the determination means 19 has a function of receiving the chromaticity data from the colorimeter 17, determining the degree of contamination of the moving handrail 1 based on the chromaticity data, and determining whether cleaning is necessary. The command means 20 is
It has a function of issuing an operation command to drive the cleaning device 4 when it is determined by the determination means 19 that cleaning is required.

Next, the operation of the embodiment in which the judging means 19 judges the dirt of the moving handrail 1 by the Lab colorimetric chromaticity diagram (JIS: Z-8792) will be described.

In the Lab color system, the color gradually approaches yellow from the origin on the positive coordinate on the vertical axis to yellow on the negative coordinate and blue on the negative coordinate on the horizontal axis, gradually approaches green to the red on the negative coordinate on the horizontal axis, and approaches the origin from the outside of the circle. The color is displayed as coordinate points on the chart in FIG. 6 that approaches black as it moves. When the moving handrail 1 becomes dirty, it becomes a dark color and its saturation approaches 0, so it is displayed at a position near the origin on the chart. To be done.

Therefore, in the embodiment, the tristimulus values of the color of the moving handrail 1 measured by the sensor 16 are input to the colorimeter 17, and the initial hue and saturation of the moving handrail 1 calculated by the colorimeter 17 are calculated. Is specified as point A on the chart of FIG. On the other hand, the cleaning required area D is set in advance on the chart of FIG. 6, and the determining means 19 is set to determine that cleaning is required when the calculated value of the colorimeter 17 enters D. .. Therefore, when the passenger conveyor is used and the moving handrail becomes dirty over time, the calculated value in the colorimeter 17 becomes point B, and when time further elapses, it reaches point C. In this state, since the calculated value of the colorimeter 17 is within the area D, the determination means 19 supplies the determination necessary signal to the command means 20, and the drive signal from the command means 20 activates the cleaner 4 to move the handrail. 1 cleaning is performed and the calculated value in the colorimeter 17 is D
Cleaning continues until it reaches a preset location outside. The degree of dirt on the moving handrail 1 and the effect of cleaning are determined by the control device 1
The display device 18 can be connected to the display device 5 to quantitatively confirm the display. In this case, using a timer in which the average time required to remove dirt on the moving handrail 1 is set in advance,
You may make it clean for a predetermined time.

As described above, according to the embodiment, when the dirt on the moving handrail 1 of the passenger conveyor falls within the predetermined dirt black range which is set in advance on the Lab color system chromaticity diagram, the drive signal is output from the command means 20. The moving handrail 1 is automatically discharged until it is emitted, and the cleaning device 4 operates to reach a predetermined cleaning degree. In this case, since the cleaning is performed when the moving handrail 1 is detected to be dirty to the extent that the cleaning is necessary, wasteful wear of the cleaning liquid and the parts of the cleaning machine is prevented, and the cleaning cost is significantly reduced. Further, in the Lab colorimetric chromaticity diagram, various colors can be displayed on the same chart, so in the embodiment, it is necessary to apply the adjustment to all passenger conveyors without making adjustment settings according to the color of the moving handrail 1. You can

In the embodiment, the photoelectric sensor and the color system are used to detect the stain, and the stain is determined based on the Lab color system chromaticity diagram.
