When an escalator is operated upward, the footstep 7 is moved toward the left and dust adhering to the footstep 7 is removed by means of the partition plate 16 so as to be scattered backward, however, the dust is not moved backward but accumulated in a part λ between the both partition plates 16 as the cleaning brush 12 is brought into contact with the footstep 7. When the escalator is operated downward, the footstep 7 is moved toward the right and dust adhering to the foot step 7 is removed by means of the partition plate 16 so as to be scattered backward, however, the dust is not moved backward but accumulated in a part Ο between the both partition plates 16 as the cleaning brush 12 is brought into contact with the footstep 7. The partition plates 16 are brought close to the footstep 7 as much as possible if they are made of nonmetallic material, while a clearance (e) is arranged between the footstep 7 and the partition plates 7 if they are made of metallic material.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning a step on a passenger conveyor such as an escalator and a moving pavement.

[0002]

2. Description of the Related Art For example, as described in Japanese Patent Application Laid-Open No. 58-224979, a single row of cleaning brushes is used for removing dust adhering to a step.

[0003] When removing dirt from a step with a cleaning brush, most of the dirt scatters behind the cleaning brush in the moving direction of the step. A small amount of dust scattered in front of the cleaning brush accumulates near the cleaning brush, but most of the dust scattered backward accumulates in the vicinity of the cleaning brush, but the rest accumulates deep behind the cleaning brush.

For example, when a cleaning device is installed in a driven machine room of a man conveyor and the moving direction of the step is from a driving side to a driven side, dust that has fallen on the step while a passenger is riding is cleaned. Most are removed by the brush and are deposited near the rear of the cleaning brush, but the remainder is scattered and deposited deep behind the cleaning brush, that is, in the middle of both machine rooms.

Although it is easy to clean dust accumulated near the cleaning brush, it is necessary to remove a step to clean dust accumulated in an intermediate portion, and much labor is required.

When the moving direction of the step is from the driven side to the driving side, dust falling on the step while the passenger is riding is removed by the cleaning brush, and the vicinity of the rear portion of the cleaning brush, ie, the driven side machine Although it accumulates in the room, it scatters and accumulates in the entire machine room, so it was troublesome to clean the refuse, although not as much as described above.

In Japanese Patent Application Laid-Open No. 58-224979, a device for sucking scattered dust is provided to prevent the above-mentioned problem. However, since the suction device is located below the cleaning body, light powdery dust cannot be removed. It may scatter and not be sucked. In addition, since the suction device is disposed at the lower portion, the machine room needs to be deepened accordingly.

In addition, the cleaning device is installed in either the driving side or the driven side machine room.

As described above, when the cleaning device is installed only on the driven side and the moving direction of the step is from the driving side to the driven side, and when the moving direction is from the driven side to the driving side, as described above. Inconveniences such as accumulation in the middle part of the garbage occurred, and much labor was required for cleaning the refuse.

When the cleaning device is installed only on the driving side, the situation is the same as described above.

[0011]

After the dust attached to the steps is removed by a cleaning brush, the dust is deposited near the cleaning device so that the dust does not fly into the machine room or accumulate in the middle of the machine room. Makes cleaning work easier.

[0012]

Means for Solving the Problems In addition to the cleaning brush, a partition plate that is in contact with or not in contact with the step is provided in front of and behind the cleaning brush with respect to the moving direction of the step. The partition plate may be provided with a brush similar to the cleaning brush before and behind the cleaning brush.

The partition plates provided before and after the cleaning brush are in contact with the floor of the machine room so that dust that has fallen from the steps and accumulated on the floor can be scraped out when the cleaning device is pulled out. Further, if necessary, the step cleaning device is attached to both the driving-side machine room and the driven-side machine room that drive the step surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is an overall view of an escalator, in which the cleaning device of the present invention is mounted on a driven machine room of a step. FIG. 2 is a detailed view of the present invention, and FIG. 2B is a detailed view of a cleaning brush mounting portion.

In the figure, 1 is a frame, 2 is a driving device, 3 is a driving drum, 4 is a driven drum, 5 is a handrail belt, 6 is a step chain, and 7 is a step. The step 7 of the escalator is fixed to the step chain 6, and the step chain 6 is wound around the driving drum 3 and the driven drum 4. When the driving drum 3 is driven by the driving device 2, the step 7 moves. The handrail belt 5 moves at a speed synchronized with the step 7.

In FIGS. 2 (a) and 2 (b), reference numeral 12 denotes a cleaning brush.
1 and the mounting bracket 11 is fixed to the arm 10 by bolts 15.

The arm 10 is fixed by the bracket 8 and the bolt 9 so as to sandwich the metal fitting 1a fixed to the frame 1. Also, an arm 1 is provided below the mounting bracket 11.
A scraper 11a having the same thickness as 0 is provided so that the scraper 11a and the arm 10 are in contact with the floor 1b of the frame.

The arm 10 is attached and fixed to the left and right of the step at a position larger than the entire width of the step 7.

In this embodiment, the moving direction of the step 7 is
The cleaning brushes 12a and 12b are provided as partition plates provided before and after the cleaning brush 12. The mounting method is the same, and a scraping plate 11 is provided below the mounting bracket 11.
a is provided.

According to the present embodiment, for example, when the escalator is in the ascending operation, the step 7 moves to the left as shown in FIG. The refuse adhering to the step 7 is a cleaning brush 12a.
Is removed by the cleaning brush,
Because it is in contact with the step 7 due to 2, do not go backwards,
It accumulates between the two brushes, that is, at the portion A in the figure.

When the escalator is in a descending operation, the step 7
Moves to the right in FIG. The dirt adhering to the step 7 is removed by the cleaning brush 12b and scatters behind. However, since the cleaning brush 12 is in contact with the step 7, it does not go rearward. Deposits on parts.

The above description is for the case where the cleaning brushes 12a and 12b have the same cleaning performance as the cleaning brush 12. However, when the cleaning performance is merely the scatter prevention function and there is no cleaning performance, the debris adhering to the step 7 is removed by the cleaning brush 12a. Is removed by
For the reasons described above, dust is deposited on the portion (b) in the escalator operation during the ascending operation and on the portion (a) during the descending operation.

Now, after a certain period of time, garbage collects too much and needs to be cleaned periodically. As described above, garbage removed by the cleaning brush accumulates in the cleaning device regardless of the operation direction of the escalator. Therefore, it is only necessary to clean this part.

The cleaning method can be easily performed by removing the left and right arms 10 from the frame 1a and pulling the cleaning device forward. That is, as described above, the mounting bracket 11
Scraper 1 at the bottom of the frame so as to be in contact with the floor 1b of the frame
Since the arm 1a is provided, when the arm 10 is pulled out, the accumulated dust is also drawn out, so that cleaning can be easily performed. Here, if the size of the machine room portion of the frame 1 is small, that is, if the size from the arm 10 to the frame end 1c in FIG. 2 is small, there occurs a problem that the cleaning device is not completely pulled out, but as shown in the figure. The problem can be solved by dividing the arm 10 into two parts and connecting them with the joint 20 and the bolt 21. First, after the arm 10 is pulled out as far as possible, the joint 20 is removed, the arm is taken out, and the cleaning device is further pulled out so that the refuse can be brought to the front.

FIG. 3 shows another embodiment of the present invention. That is, before and after the cleaning brush 12, the cleaning brush 12
FIG. 3B is a detailed view of a partition plate attaching portion. The partition plate is made of a non-metallic material, and if there is no danger of being scratched even if it comes in contact with the step 7, it is better to make contact with the step 7 as much as possible to prevent dust from leaking. When a metal is unavoidably selected, a gap e is provided between the partition plate 16 and the step 7 as shown in FIG.

In the cleaning device of FIG. 3, as described above, the cleaning device of FIG.
Has the same effect as that of the cleaning device, but the description is omitted.

With the above-described cleaning device, most of the dust attached to the step can be collected near the cleaning device. However, the cleaning device is installed in both the machine room on the driving side and the machine room on the driven side of the step. By doing so, it is possible to accumulate garbage in the cleaning device in a more nearly complete state.

That is, during the escalator lowering operation, debris that has fallen to the step while a passenger is riding can be removed and collected by the cleaning device of the driven machine room, and similarly during the ascending operation, the dust in the driving machine room can be reduced. It can be removed and collected by a cleaning device.

Therefore, irrespective of the operation direction of the escalator, most of the refuse falling from the passenger can be collected in the cleaning devices installed in both machine rooms, and only a small amount is accumulated in the middle part of the machine room.

[0031]

According to the present invention, debris on the steps dropped from the passenger is removed by the cleaning brush, and even if the debris scatters behind the cleaning brush, the debris is sealed by the partition plate, so that debris accumulates in the cleaning device. . Therefore, dust is not scattered throughout the machine room, and only a small amount is deposited in the middle of the machine room.
