Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a step cleaning device for a passenger conveyor for cleaning dust and the like adhering to the steps to prevent malfunction of the safety device.

[0002]

2. Description of the Related Art Conventionally, as a step cleaning device of this type,
For example, Japanese Utility Model Laid-Open No. 62-8281 and Japanese Patent Laid-Open No. 52-11.
1184 and Japanese Patent Laid-Open No. 52-124682.

FIG. 4 is a schematic configuration diagram showing a conventional man conveyer disclosed in Japanese Patent Laid-Open No. 52-124682, FIG.
FIG. 5 is a side view showing an enlarged main part of FIG. 4. In the figure, 1 is a truss of a man conveyor, 2 is a step, 3 is a step 2
It is a balustrade erected on the truss 1 on both sides of.

Reference numeral 4 is a drive roller for the step 2, 5 is a drive roller rail for guiding the drive roller 4, 6 is a follower roller for the step 2, 7 is a follower roller rail for guiding the follower roller 6, and 8 is a machine chamber wall. The step cleaning device 8 is attached to the step 9, and the step cleaning device 8 has a brush 8a that comes into contact with the step plate 2a of the step 2.

Next, the operation will be described. When the step cleaning device 8 is operated during the operation of the man conveyor, the brush 8a comes into contact with the step plate 2a of the step 2 in FIG. 5, and the step plates 2a are automatically and sequentially cleaned.

[0006]

In the conventional step cleaning device constructed as described above, although the tread 2a can be cleaned, the riser 2b of the step 2 cannot be cleaned, and therefore the hair below the riser 2b cannot be cleaned. Dust easily accumulates, which may cause the SRS (step roller switch) and other safety switches to malfunction, which may cause an accident due to a sudden stop of the conveyor, and it may take time to recover after the stop and investigate the cause. There was a problem such as being expensive. Further, in order to manually clean the riser 2b at the time of maintenance, since the work covers all steps 2, there is a problem that a large amount of labor is required.

The present invention has been made to solve the above problems, and it is possible to easily prevent dust from accumulating in the lower portion of the riser of a step, which causes malfunction of the safety switch. It is an object of the present invention to provide a step cleaning device for a passenger conveyor that can prevent the above-mentioned problems and reduce the maintenance labor.

[0008]

SUMMARY OF THE INVENTION A step cleaning device for a man conveyor according to the present invention includes a cleaning tool for contacting a lower part of a riser of a moving step to clean a lower part of the riser during operation of the man conveyor. It is attached to the folded part of the rail that guides the movement.

[0009]

According to the present invention, the cleaning tool attached to the rail is brought into contact with the lower portion of the riser to prevent dust from accumulating in the lower portion of the riser without extra effort, and the safety switch malfunctions due to the dust. Prevent.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing an essential part of a passenger conveyor having a step cleaning device according to an embodiment of the present invention, FIG. 2 is a front view of FIG. 1, and FIG. 3 is a front view showing a mounting state of an SRS of the passenger conveyor of FIG. It is a figure, and the same code | symbol is attached | subjected to FIG.4 and FIG.5 or an equivalent part, and the description is abbreviate | omitted.

In the figure, 11 is a rail 7 for a follower roller.
Is a cleaning tool screwed to the semi-circular folded-back part of the brush, for example, a brush made of hard nylon, and this brush 11 comes into contact with the lower portion 12 (FIG. 2) of the riser 2b of the step 2 during operation of the man conveyor, To clean. Reference numeral 13 is an SR as a safety switch attached to the follower roller rail 7.
The SRS 13 is a switch for detecting the lifting of the follower roller 6 and stopping the operation of the man conveyor when an object is sandwiched between the adjacent steps 2 or the tread 2a sinks. . Reference numeral 14 is an SRS relay, and 14a is an electric contact operation unit thereof. Also, the tread 2
The cleaning of a is performed by the same device as the conventional example, but is omitted here.

Next, the operation will be described. The step 2 is guided and moved by the driving roller rail 5 and the following roller rail 7 by the operation of the man conveyor, but the brush 11
When the step 2 is rotated, the brush 11 comes into contact with the lower portion 12 of the riser 2b. As a result, the dust on the lower portion 12 of the riser 2b is automatically cleaned and removed without any trouble. Therefore, the SRS 14 of FIG.
When passing through, the lower part 12 of the riser 2b is cleaned, and the sudden stop of the passenger conveyor due to the malfunction of the SRS 14 is prevented.

In the above embodiment, the brush 1 is used as a cleaning tool.
Although 1 is shown, another one may be used as long as dust can be removed from the lower portion 12 of the riser 2b. Further, although the escalator is illustrated as the passenger conveyor in the above embodiment, it goes without saying that the present invention can be applied to a moving walkway as well.

[0014]

As described above, the step cleaning device for a man conveyor according to the present invention includes a cleaning tool for cleaning the lower part of the riser by contacting the lower part of the riser of the moving step during operation of the man conveyor. Since it is attached to the folded part of the rail that guides the movement of the, it is possible to easily prevent dust from accumulating at the lower part of the riser of the step, which can prevent the malfunction of the safety switch and the safety of the man conveyor. And reliability can be improved,
This has the effect of significantly reducing the maintenance labor.
