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 moving tread plate used for a passenger conveyor such as an escalator or a moving sidewalk.

[0002]

2. Description of the Related Art Generally, in a passenger conveyor, a large number of moving treads are connected in a loop so as to move between upper and lower entrances. And many uneven cleat grooves are formed on the upper surface of these moving treads,
While the vehicle is moving, dust and dirt, stone chips, metal powder, and other dirt and foreign matter adhering to the soles of the passengers adhere to the cleat grooves. It is provided in.

Heretofore, as described in Japanese Patent Application Laid-Open No. 10-279255, for example, the above-mentioned cleaning device is provided with an uneven surface so as to be mounted on a comb and a floor plate portion so as to make sliding contact along the upper surface shape of a movable tread plate. There has been proposed a device provided with a brush-made cleaning device (cleaning tool) in which fine fibers projecting in a stepped shape are bundled. In order to maintain the beautiful appearance and the clean feeling of the upper surface of the movable tread, the brush is designed to be constantly cleaned without manual operation.

[0004]

Here, in the above-mentioned conventional cleaning device, there is no consideration given to the life caused by abrasion or habit of the brush tips while the cleaning tool is in sliding contact with the moving tread plate. And had to be replaced frequently, which led to conservation and economic problems. That is,
The brush flies so as to be constantly pushed in the traveling direction of the moving tread plate due to the sliding contact force on the moving tread plate and the influence of foreign matter. As a result, the fluttering state becomes habit and loses the cleaning ability, and the life is extended. This is the phenomenon. This phenomenon occurs when the moving tread is moving upward, the brush tip of the upper entry / exit gate is turned up to the side opposite to the comb tip, and the life is extended. The brush bristles are set to a state where the bristles of the brush are turned up on the same side as the teeth of the comb, thereby extending the life. On the contrary, in the case of the downward movement, the brush is turned up in the opposite direction to the case of the upward movement, and the life is extended. It is known that the habit of the brush is particularly serious when the fine fibers constituting the brush are hardened by dust or metal powder, and the life is further shortened. In addition, there is a great economical problem that the entire cleaning device must be treated as disposable when the brush of the cleaning tool is used up.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a cleaning device for a movable tread plate capable of significantly increasing the service life and reducing the cost as compared with the conventional method.

[0006]

A tooth is provided at a doorway at which a moving tread plate enters and exits, and is attached to a floor plate portion disposed immediately above the moving tread plate and engages a cleat groove formed on the upper surface of the moving tread plate. A comb having a point, and a cleaning device for a movable tread, which is mounted on the floor plate portion and is made of a brush-made cleaning tool that is in sliding contact with an upper surface of the moving tread under the comb, wherein the cleaning tool includes the moving tread. The cleaning tool is attached to a floor board in a direction from which the movable tread board comes out, after being attached to the floor board in the entering direction for a certain period of time. A comb provided at an entrance through which the moving tread enters and exits, attached to a floor plate portion disposed immediately above the moving tread, and having a tooth tip engaged with a cleat groove formed on an upper surface of the moving tread; A cleaning device for a moving tread, comprising a brush-made cleaning tool that is mounted on a floor plate and slidably contacts the upper surface of the moving tread plate below the comb, wherein the cleaning tool is mounted on the floor plate in a direction in which the moving tread plate comes out for a certain period of time. Thereafter, the cleaning tool is mounted on a floor plate in a direction in which the movable tread plate enters.

According to the present invention, as described above, the brush of the cleaning device cleans the moving tread plate moving in one direction at one of the entrances and exits for a certain period of time, and after the hauling or abrasion occurs, the other is stepped on the other. By moving the mounting place to the mouth and sliding on the upper surface of the moving tread that moves in another direction, it turns up in the opposite direction to the original habit and starts cleaning again, and in this state the original habit is Once again, cleaning for a certain period of time becomes possible. By changing the place where the brush is attached to the floor plate at regular intervals, the life of the brush due to its habit can be extended. This has the effect that one brush can be reused by moving the original brush to the other, as described above, although it has been replaced by the use of one of the doors at the end of its service life. This means that the life can be extended at least twice as much as the conventional one. Therefore, it can be said that the maintenance cost can be greatly reduced.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a moving stepboard cleaning apparatus according to an embodiment of the present invention.

FIG. 1 is a perspective view showing a main part of a passenger conveyor (escalator) 1 provided with a cleaning device of the present invention in a perspective view around a lower entrance 2 at a lower portion, and FIG. 3 is a cross-sectional view corresponding to FIG. 2 (although the direction is opposite to FIG. 2) at the upper entrance which is not shown in FIG.

In the figure, a passenger conveyor 1 to which the present invention is applied has a large number of moving treads 4 connected in a loop from a lower entrance 2 which is one of the entrances to an upper entrance 3 (FIG. 3). In this state, the passenger is carried while moving in synchronization with the handrail 6 provided on the periphery of the balustrade 5 standing upright on both sides of the movable tread plate 4. Here, both entrances 2 and 3 are composed of floor boards 2A and 3A which are strength members, and front boards 2B and 3B which respectively cover the surfaces thereof. Combs 7 having a large number of tooth tips 7A meshing with the uneven cleat grooves 4A provided on the surface of the tread plate 4 are fixed to the floor boards 2A and 3A by screws 8. Further, between the comb 7 and the floor plates 2A and 3A, a cleaning device 10 including a fixing piece 10A and a brush 10B constituting a cleaning tool 9 is provided.
Are fixedly mounted. In the case of an ascending operation in which the movable tread plate 4 comes out of the entrance 2, it is attached to the lower entrance 2 as shown in FIG. 2. in this case,
The cleaning tool 9 constitutes the cleaning device 10 by a single body or a plurality of bodies divided into several sets in the width direction of the floor plate 2A. Usually, the fixing piece 10A is made of a plastic material or a steel material that is easy to process. On the other hand, a brush made of a very thin wire made of a plastic material or a steel material and having a certain thickness is used as the brush 10B, and one end of the brush 10B is planted on the fixed piece 10A. By automatically bringing the bristle tip into sliding contact with the inner surface of the cleat groove 4A, cleaning is always performed automatically.

When the passenger conveyor 1 moves up and the cleaning device 10 is attached only to the lower entrance 2, the brush 10B that slides on the inner surface of the cleat groove 4A.
Is turned up along the arrow X (FIG. 2), which is the moving direction of the moving tread plate 4, and starts to have a habit. For example, after a certain period of three months, the habit is hard to return to its original state, and its life is shortened by abrasion due to sliding contact. I will approach you. In this case, the abrasion of the brush 10B is caused by the rear side 10a that directly and strongly contacts the inner surface of the cleat groove 4A.
It is known from experience that the front side 10b is hardly damaged. Here, as described above, for example, if the cleaning ability is lost in three months and the life is determined, the life is extended by the following measures.

That is, the life extension according to the present invention is to move the cleaning tool 9 (fixing piece 10A and brush 10B) used in FIG. 2 to the upper entrance 3 as shown in FIG. is there. In this case, the moving direction of the moving tread plate 4 is opposite to the direction shown in FIG. 2 as indicated by an arrow Y (FIG. 3), and the brush 10B has its unbroken front side 10b slidably in contact with the cleat groove 4A and starts fresh cleaning. And, for example, cleaning is automatically continued for a certain period of three months,
In this way, one cleaning device 10 ensures a service life substantially equivalent to twice that of a conventional cleaning device.

In the above example, a method of moving one cleaning tool 9 (fixing piece 10A and brush 10B) from the lower entrance 2 to the upper entrance 3 has been described. When two cleaning tools 9 are attached to the lower entrance 2 and the upper entrance 3 from the beginning and two places are cleaned at the same time as shown in FIGS. After a certain period of three months, the cleaning tool 9 attached to the lower entrance 2 is moved to the upper entrance 3.
On the contrary, by changing (replacement) the attachment place of the cleaning tool 9 attached to the upper entrance 3 to the lower entrance 2, the life extension is twice as long as the conventional one as described above. Can be achieved. Further, the present invention can be applied in common to a case where the cleaning tool 9 is attached to only the lower portion, only the upper portion, or both the lower portion and the upper portion of each entrance.
