BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of a passenger conveyor according to the present invention will be described with reference to FIGS.

FIG. 1 is a perspective view showing the structure of an embodiment of a passenger conveyor according to the present invention. The passenger conveyor 1 of the present invention forms a main frame 2 installed slantingly over a lower floor F1 and an upper floor F2, and a lower entrance 3 and an upper entrance 4 at the upper and lower parts of the main frame 2. The horizontal lower loading / unloading floor 5 and the upper loading / unloading floor 6 and the lower loading / unloading floor 5 and the upper loading / unloading floor 6 which are endlessly connected by a well-known step chain (not shown here).
A step 7 formed between the step 7 and the balustrade 8, which is erected along both sides of the step 7 in the moving direction, a handrail 9 which is guided by the periphery of the balustrade 8 and moves in synchronization with the step 7, 7
And a control device 10 for controlling the operation of the handrail 9.

In the present embodiment, in particular, the measuring means 11 for detecting the temperature of the constituent equipment of the passenger conveyor and the snow accumulated on the passenger conveyor, and the heating devices 13, 14, 15 for heating the constituent equipment of the passenger conveyor are provided. ing. The installation position of the measuring means 11 is not limited to the illustrated position, and the temperature may be the outside air temperature or the temperature of the upper boarding / alighting floor 6 or the like. Further, the number and arrangement position of the heating devices 13, 14, 15 are also arbitrary, and they do not generate heat by themselves, and can also be used as means for passively introducing energy with a hot water pipe or the like. The control device 10 predicts freezing or snow on the basis of the measurement value from the measuring means 11 during the time when the passenger conveyor 1 is not in the commercial operation, and the upper boarding / alighting when the freezing or snow is predicted. There is provided operation instruction means for moving the steps 7 and the handrails 9 toward one of the floors 5 and 6 of the floor 6 and the lower floor 5 on which it is easy to discharge ice and snow to the outside.

FIG. 2 is a diagram showing a control procedure of the control device 10 when the drive system of the step 7 and the handrail 9 is driven during freezing and snow in the embodiment of FIG. The measuring means 11 detects the temperature of the components 1 to 10 of the passenger conveyor 1 and snowfall on the passenger conveyor 1. Control device 1
0 predicts freezing or snow accumulation based on the measurement value from the measuring means 11 during a time period when the passenger conveyor 1 is not in commercial operation, for example, at night. Not too cold, eg 5 ° C
As described above, when it is determined that there is no freezing or snow, power is wasted, so the steps 7 and the handrail 9 are stopped as usual.

On the other hand, for example, when the temperature is below 5 ° C. and snow is flickering, and freezing or snowfall is predicted, one of the upper and lower loading floors 6 and the lower loading and unloading floor 5 which is likely to discharge ice or snow to the outside. An operation command is issued to move the steps 7 and the handrail 9 toward the boarding / alighting floor 5 or 6 side. In that case, since it is sufficient to prevent freezing and snow accumulation, the moving speed of the step 7 and the handrail 9 should be slower than the normal 30 m / min, for example, 15 m / min or 10 m / min. Save power.

FIG. 3 shows that, in the embodiment shown in FIG. 1, the drive system is operated and the heating devices 13 and 1 are operated at the time of freezing and snow.

The measuring means 11 detects the temperature of the components 1 to 10 of the passenger conveyor 1 and snowfall on the passenger conveyor 1. The control device 10 predicts freezing and snow on the basis of the measurement value from the measurement means 11 during a time period when the passenger conveyor 1 is not in commercial operation, for example, at night.

When it is determined that the temperature is not so cold, for example, at 5 ° C. or higher and there is no freezing or snow, power is wasted, so the steps 7 and the handrail 9 are stopped as usual.

On the other hand, for example, when the temperature is below 5 ° C. and snow is flickering, and freezing or snow is predicted, it is easy to discharge ice or snow to the outside of the upper loading / unloading floor 6 and the lower loading / unloading floor 5. An operation command is issued to move the steps 7 and the handrail 9 toward the boarding / alighting floor 5 or 6 side. In that case, it is sufficient to prevent freezing and snow, so step 7
In the same manner as above, the moving speed of the handrail 9 is set to be lower than the normal 30 m / min to save power.

In the embodiment of FIG. 3, it is also determined based on the measurement value from the measuring means 11 whether or not the heating devices 13, 14, 15 should be operated. When it is determined that the weather condition should be activated, the operation of moving the steps 7 and the handrail 9 and the heating by the heating devices 13, 14, 15 are used in combination, so that particularly in a severe cold region. Even more effective.

Note that the weather conditions such as the temperature that is the criterion for starting the operation of moving the steps 7 and the handrail 9, and the weather conditions such as the temperature that is the criterion for starting the heating by the heating devices 13, 14, and 15. And need not be the same number.

According to the embodiment of the present invention, component devices will not be damaged due to freezing or the like during the start-up operation of the next morning when the operation is started after nights under freezing or snow conditions.

By the time of the start-up operation of the next morning, the frozen ice or the accumulated snow will be collected on the boarding / alighting floors 5 or 6 on the side that is easily discharged to the outside of the passenger conveyor 1. If there is a road or aisle side, it can be easily discharged to the road surface, and if it is the platform side of the station, it can be easily discharged to the track.

When the operation of moving the steps 7 and the handrail 9 and the heating by the heating devices 13, 14, 15 are used together, the effect is further enhanced.

For non-business operation such as nighttime, it is sufficient to prevent freezing and snow accumulation. Therefore, low-speed operation can reduce power consumption.
