Description

TECHNICAL FIELD The present invention relates to a window cleaning device for automatically cleaning wall surfaces of building window glass, exterior plates and the like.

(B) Conventional technology Generally, window glass, exterior panels, etc. (hereinafter referred to as wall surfaces) of a building are manually cleaned,
Several inventions have been proposed in the past to automate this by a machine from the viewpoint of crash disaster prevention and work rationalization.

These inventions basically consist of means for wiping off stains on the wall surface and means for supplying washing water (hereinafter, simply referred to as water) for wiping. Among these, as the prior art of the invention of the present application, There are the following two inventions.

(a) An invention consisting of a cleaning roll brush that moves up and down the wall surface and a nozzle provided on the sash vertical member of the curtain wall (Japanese Patent Publication No. 53-17819).

(b) Invention comprising a cleaning wiper that moves up and down on the wall surface and an absorbent sponge for collecting water that moves up and down on the wall surface together (Japanese Patent Publication No.
9-33846 invention).

C) Problems to be Solved by the Invention However, in the invention of (a) above, since the nozzle for supplying water is provided in the sash vertical member, a huge number of nozzles corresponding to the total length of the wall surface to be cleaned is provided. It is impractical to install nozzles, and it is uneconomical and meaningless to eject water from all nozzles at the same time, and the cleaning roll brush selectively ejects water only from the approaching nozzle. There is a problem that a control mechanism to operate is required.

On the other hand, in the invention of (b) above, since water is supplied from the absorbent sponge for stored water that moves up and down the wall surface together with the cleaning wiper, the above problem does not occur, but this time the water is absorbed in the absorbent sponge for stored water. A water supply hose to supply is required, and the total length of this water supply hose is unrealistic because it depends on the total length of the wall to be cleaned, and a complicated mechanism for treating the water supply hose accompanying the vertical movement of the absorbent sponge. There was a problem that it was necessary.

An object of the present invention is to solve the above problems of the prior art and to provide an automatic window wiping device which can be easily put into practical use.

D) Means for Solving the Problems The automatic window cleaning device of the present invention comprises a guide rail 1 provided along a sash vertical member S of a curtain wall, and an elevator 10 supported by a pair of adjacent guide rails.

The guide rail 1 has a hollow shape so that the inside 2 serves as a water flow path, and has a configuration in which a vertical slit 3 is provided on the front surface so that a part of the elevator 10 can be fitted inside. The elevator 10 includes a base 11 that is vertically movably supported by a guide rail, a water receiving plate 18 that is fitted into the guide rail to receive the water that has been passed through, and a sprinkling pipe 20 that sprinkles the water received by the water receiving. A cleaning roller 22 impregnated with water sprinkled from a sprinkling pipe and rotating on the wall surface; a squeezing roller 24 that presses against the cleaning roller to squeeze the water impregnated into the cleaning roller; and water squeezed from the cleaning roller again. Each member of the drainage guide 28 that allows water to pass through the guide rail is arranged in order from the top, and a wiper 31 that is slidably contacted with the wall surface is arranged above the cleaning roller.

(E) Action Accordingly, the automatic window cleaning device of the present invention has a basic action of cleaning the wall surface by the cleaning roller 22 impregnated with water, and further lowering the elevator 10 while wiping off the water remaining on the wall surface by the wiper 31. Together with this, the following unique action will occur.

That is, in the automatic window cleaning device of the present invention, the water that has passed through the inside 2 of the guide rail 1 from above is received by the water receiving plate 18 of the elevator 10, and this water is sprinkled on the cleaning roller 22 by the sprinkling pipe 20.・ Impregnated and cleaning roller 2
2, the impregnated portion is pressed against the wall surface S of the building by rotation and the dirt is wiped with water. Further, at this time, the dirty water impregnated in the cleaning roller is dehydrated by the squeeze roller 24, and the squeezed water is discharged by the drainage guide 28. A series of actions of causing water to pass through the guide rail 1 again occurs.

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

FIG. 5 is a view showing an example of a guide rail of the automatic window cleaning device of the present invention.

Here, the guide rail 1 is formed integrally with the sash vertical member S of the curtain wall, and has a hollow prismatic shape with a hollow cross section in which the inside 2 has a water flow path, and an elevator 10 to be described later.
A vertical slit 3 is provided on the front surface so that the carriage 12 can be fitted therein.

In the figure, G is a wall surface (here, a glass surface), and C is a caulking member.

1 to 4 are views showing an example of an elevator of the automatic window cleaning device of the present invention.

The elevator 10 is supported by the guide rail 1 so as to be vertically movable. Here, the carts 12 located at both ends of the base 11 are fitted into the guide rail 1 so as to be vertically movable. .

The dolly 12 is provided by bending both ends of the base 11 in a U-shape, and a part of the dolly 12 is fitted into the inside 2 of the guide rail through the slit 3 of the guide rail (eighth embodiment).
See figure).

Then, inside the guide rail 1 of the carriage 12, there are support rollers 13 that should come into contact with both sides of the guide rail inner wall to roll, and support rollers 14 that should come into contact with the top, bottom, left, and right, and also come in the front direction. Support rollers 15 which are provided on the upper side and contact with the outer wall of the guide rail in the front direction and should be rolled are provided on the outer side, respectively.

Therefore, the carriage 12 is supported by the support roller 13 in the left-right direction with respect to the guide rail 1, and is also supported in the front-rear direction by the support rollers 14 and 15 (see FIG. 8).

A water receiving plate 18, a sprinkler pipe 20, a cleaning roller 22, and a base 11 supported on the guide rail 1 by the dolly 12 described above.
Each member of the squeezing roller 24, the cleaning roller 25, the squeezing roller 27, and the drainage guide 28 is provided in order from above, and
A wiper 31 is provided above the cleaning roller 22.

FIG. 7 is a perspective view showing a water receiving plate.

The water receiving plate 18 is formed by a plate-shaped material (rubber is used in this embodiment) having a high elasticity and slidability into a flat shape that can be slidably fitted inside the guide rail 1. It is attached to 12 in a brim shape.

A part of the water receiving plate 18 is exposed to the outside of the guide rail by a trough-shaped communicating portion 18a that can pass through the slit 3 of the guide rail 1, and a pipe 19 communicating with the sprinkler pipe 20 is provided at the end of the communicating portion 18a. It is installed vertically.

Therefore, the water receiving plate 18, which is slidably fitted in the guide rail as if it were a packing, receives the water that has been passed from above and passes it through the communicating portion 18a and the pipe 19 to sprinkle the water.
Fulfill the action of inducing.

The sprinkling pipe 20 is installed over the cleaning roller 22 described below over the entire length thereof, and has a function of sprinkling water on the cleaning roller from a large number of nozzles 21 formed therein.

The cleaning roller 22 is formed of a material having a high elasticity and impregnation property (a sponge is used in this embodiment) in a columnar shape, and the cleaning roller 22 is attached to the base 11 so that its circumferential surface is pressed against the wall surface G of the building. When stopped, the water impregnated by the rotation serves to wipe off dirt on the wall surface (see FIG. 4).

A squeezing roller 24 is pressed below the cleaning roller 22 and serves to squeeze out the dirty water impregnated in the cleaning roller.

In this embodiment, a second cleaning roller 25 and a diaphragm roller 27 are further arranged below the cleaning roller and the diaphragm roller to ensure a more reliable cleaning action.

That is, the lower cleaning roller 25 first pre-washes the wall surface S with the dirty water squeezed from the upper cleaning roller 22.
Next, the upper cleaning roller 22 performs the function of finishing and washing the wall surface S with clean water.

By the way, the driving of the cleaning roller is performed by lowering the elevator 10 in this embodiment.

That is, the pulley 17 provided on the support roller 15 of the carriage 12
By connecting the pulley 26 provided on the cleaning roller 25 and the pulley 23 provided on the cleaning roller 22 with the belts 32 and 33, the support roller 15 accompanying the lowering of the elevator 10 is connected.
The cleaning rollers 25 and 22 are forcibly rotated by the rolling of the.

In this case, it goes without saying that the number of rotations of the cleaning rollers 25 and 22 is set to be larger or smaller than the rolling caused by the contact with the wall surface S to cause a frictional action with the wall surface.

Next, reference numeral 28 in the drawing is a drainage guide for recirculating the dirty water squeezed by the cleaning roller as waste water into the guide rail.

The drainage guide 28 is composed of a receiving tray 29 which is installed over the entire length below the cleaning roller 25, and a drainage pipe 30 which is connected to the receiving tray. By inserting
The water accumulated in the tray 29 is passed through the drain pipe 30 into the guide rail.

Finally, 31 in the figure is a wiper for wiping off the water remaining on the wall surface S after cleaning by the cleaning roller.
It is provided above 2.

The elevator 10 configured as described above is hung while being supported by the guide rails by the wires W hung in the guide rails 1 (see FIG. 6), and a hoisting / rewinding mechanism provided on a rooftop of a building or the like. It is raised and lowered by (not shown).

In this case, it goes without saying that the hoisting / rewinding mechanism is also configured to be movable in the lateral direction, and the elevator 10 sequentially moves the wall surface in the lateral direction to perform the elevating motion each time.

G) Effects of the Invention The invention configured as described above has the following effects.

(a) Since the wall of the building can be automatically cleaned without manual labor, it is extremely useful from the viewpoint of preventing accidents and streamlining work.

(b) Since the water required for cleaning is always sprayed from the vicinity of the cleaning roller, economical and efficient cleaning can be performed without loss as in the prior art.

(c) Moreover, since the above water is passed through the guide rails and taken out from there into the elevator for watering, it does not require a long water supply hose as in the conventional technology and cleans regardless of the height of the building. Is possible, and it is especially effective for cleaning high-rise buildings.

(d) Since the water used for cleaning is again passed through the guide rails and collected, there is no risk of waste water being scattered on the ground, and cleaning work can be performed even in urban areas without special curing.

(e) Because the structure is such that the elevator is lowered onto the guide rails for cleaning, no special equipment other than laying the guide rails is required on the building side, and it is easy to implement a window cleaning device. Since it can be molded integrally with the sash vertical member, it can be economically constructed if it is prepared at the construction stage of the building without impairing its appearance.

(f) Since the guide rails not only support the elevator and pass water, but also accommodate the wire that suspends the elevator, it is possible to prevent the wire from being entangled due to strong winds, etc., thus achieving safe and reliable operation of the elevator.
