Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is suitable for use in devices that have a large number of adjacent rollers that require cleaning, such as handrail guide rollers for passenger conveyors. This invention relates to a roller cleaning device.

[Conventional technology]

The handrail guide rollers of the passenger conveyor are provided to reduce frictional resistance at the handrail folding section near the entrance/exit where the most tension is applied, and the number of these rollers is close to 100 in total per passenger conveyor. However, these guide rollers
Abrasion particles generated from the inside of the handrail, dust in the atmosphere, dirt from the treads, etc. adhere to the handrail, and these deposits cause the handrail drive mechanism to slip or accelerate wear on the back of the handrail. Therefore, it is necessary to periodically clean the outer peripheral surface of the guide roller, and a roller cleaning device is used for this purpose. Such a cleaning device is equipped with a drive roller and a cleaning piece, and the drive roller is brought into contact with the outer circumferential surface of the handrail guide roller to rotate it, and the drive roller touches the outer circumferential surface of the guide roller at different positions. The purpose is to remove the deposits using a cleaning piece that is brought into contact with the surface.

Note that known reference examples of this type of roller cleaning device include Japanese Patent Application Laid-Open No. 121585/1983 and Japanese Utility Model Application No. 1983-121585.

[Problem that the invention attempts to solve]

However, in conventional roller cleaning devices, each roller to be cleaned, such as a handrail guide roller, is rotated by a drive roller, so a support structure for positioning and supporting the drive roller is required. This made it difficult to make the device smaller and lighter. Also,
Since the contact width between the cleaning piece and the roller to be cleaned was wide, and the cleaning piece was in contact with the entire width of the outer peripheral surface of the roller to be cleaned, when this cleaning piece was made of a rigid body,
There was a problem in that the contact surface was uneven and the contact state was not uniform over the entire width of the outer circumferential surface of the roller, leaving behind deposits that should be removed. Note that it is not practical to use a brush as the cleaning piece because not only does the brush itself need to be cleaned, but also plastic deformation is likely to occur at the tip of the brush.

Therefore, it is an object of the present invention to provide a roller cleaning device that solves the problems of the prior art described above, can be made smaller and lighter, and is free from the risk of leaving deposits on the outer peripheral surface of the roller to be cleaned. It is in.

[Means for solving problems]

In order to achieve the above object, the present invention has a drive roller that is capable of rotationally driving two adjacent rollers to be cleaned at the same time by contacting the outer circumferential surfaces of two rollers to be cleaned that are adjacent to each other, and also that a cleaning piece However, it is configured to be movable in parallel to the axial direction of the roller to be cleaned which can come into contact with it.

[Effect]

That is, in the present invention, by supporting the drive roller for rotationally driving the roller to be cleaned by another adjacent roller to be cleaned, the drive roller can be positioned and supported without particularly providing a support structure. Moreover, by making the cleaning piece movable along the width direction of the outer peripheral surface of the roller to be cleaned, the contact width between the cleaning piece and the roller to be cleaned can be set narrowly.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

The figure is for explaining one embodiment of the roller cleaning device according to the present invention, and is a schematic perspective view showing the state of use thereof. Reference numeral 1 indicates the entire roller cleaning device, and 2 and 3 indicate the entrance and exit of the passenger conveyor. The handrail guide rollers 4 are provided adjacent to each other at the handrail turn-around portion in the vicinity, and these guide rollers 2,
This is a support frame that rotatably supports 3. and,
The roller cleaning device 1 includes a drive roller 5 that can contact the outer peripheral surfaces of two adjacent guide rollers 2 and 3 and drive both rollers 2 and 3 to rotate simultaneously.
and a motor 6 for driving this drive roller 5.
, a push button switch 7 for turning on and off the motor 6, and a push button switch 7 that can come into contact with the outer peripheral surface of one of the guide rollers, for example, the guide roller 2 when the drive roller 5 comes into contact with the guide rollers 2 and 3. A cleaning piece 8 and a lever 9 that can rotate this cleaning piece 8 in the direction of arrow A.
and a box 10 that accommodates and supports the lever 9 and the motor 6.

When using such a roller cleaning device 1, first remove a handrail (not shown) from the support frame 4, and then bring the drive roller 5 into contact with the outer peripheral surfaces of two mutually adjacent guide rollers 2 and 3. Katsu cleaning piece 8
is brought into contact with a predetermined position on the outer peripheral surface of one of the guide rollers 2. Then press push button switch 7 to turn motor 6 on.
When the drive roller 5 is rotated in the direction of arrow B, the guide rollers 2 and 3 are driven to rotate in the directions of arrows C and D, respectively, due to the frictional force with the drive roller 5, so that the outer peripheral surface of the guide roller 2 Adjust the contact pressure of the cleaning piece 8 against the box body 1 with the lever 9.
By moving the roller 0 in the direction of arrow E, that is, parallel to the axial direction of the guide roller 2, abrasion powder, dust, etc. adhering to the outer peripheral surface of the guide roller 2 are sequentially removed along the width direction.

In this way, the driving rollers 5 are
When the rollers 2 and 3 are brought into contact with the outer peripheral surfaces of the guide rollers 2 and 3, the drive roller 5 is held between the rollers 2 and 3. Since the guide roller 3 supports the drive roller 5, the drive roller 5 can be positioned and supported without particularly providing a support structure, and the roller cleaning device 1 can be made smaller and lighter. Further, the contact width between the cleaning piece 8 and the guide roller 2 is set to be narrow, so that by moving the cleaning piece 8 in parallel to the axial direction of the guide roller 2, the entire width of the outer peripheral surface of the roller 2 can be cleaned. As a result, there is no unevenness on the contact surface between the two, and there is no risk of deposits being left behind.

In the above embodiment, the cleaning piece 8 is moved together with the drive roller 5 by moving the box 10 in the direction of the arrow E, that is, parallel to the axial direction of the guide roller 2. If it is configured so that it can be moved in the direction of arrow E relative to the body 10, only the cleaning piece 8 can be made movable relative to the guide roller 2 without moving the drive roller 5.

[Effect of idea]

As explained above, according to the present invention, since the drive roller for rotationally driving the roller to be cleaned is supported by another adjacent roller to be cleaned, the drive roller does not need to be provided with a particular support structure. The roller can be positioned and supported, thereby making the roller cleaning device smaller and lighter, and since the cleaning piece is movable along the width direction of the outer circumferential surface of the roller to be cleaned, the cleaning piece and the roller to be cleaned can be moved easily. The contact width can be set narrowly, thereby making it possible to avoid uneven contact between the two and eliminating the risk of leaving deposits behind.
