Description

DETAILED DESCRIPTION OF THE INVENTION A) Industrial Application Field This invention relates to a window cleaning device for automatically cleaning wall surfaces such as window glass and exterior panels of buildings.

B) Conventional technology Cleaning of window glass, exterior panels, etc. (hereinafter collectively referred to as walls) of buildings is generally done manually.
Several inventions have been proposed in the past to automate this process with machines from the standpoint of preventing fall accidents and streamlining work.

These inventions basically provide means for wiping dirt off walls and cleaning water (hereinafter simply referred to as water) for wiping.
Among these, the following two inventions are particularly positioned as prior art to the present invention.

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

■) An invention consisting of a cleaning wiper that moves up and down on a wall surface and a water absorbing sponge that moves up and down the wall surface together with the cleaning wiper.
No. 9-33846 invention).

C) Problems to be Solved by the Invention However, in the above invention (a), since the nozzles for supplying water are provided on the sash vertical members, a huge number of nozzles are required depending on the total length of the wall surface to be cleaned. It is unrealistic to have to install multiple nozzles, and it is uneconomical and pointless to jet water from all nozzles at the same time, so water can be selectively jetted only from the nozzle that the cleaning roll brush approaches. There were problems such as the need for a control mechanism.

On the other hand, in the invention (b) above, water is supplied from the water absorbing sponge that moves up and down the wall surface together with the cleaning wiper, so the above problem does not occur. A water supply hose is required to supply the water, and the total length of this water supply hose depends on the total length of the wall surface to be cleaned, which is impractical, and a complicated mechanism is required to handle the water supply hose as the absorption sponge moves up and down. There were problems such as the need for

The object of the present invention is to solve the problems of the prior art as described above and to provide an automatic window cleaning device that can be easily put into practical use.

2) 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 l is hollow so that the interior 2 serves as a water flow path, and has a vertical slit 3 on the front surface so that a part of the elevator 10 can be inserted into the interior. The elevator IO has a base 11 that is supported by a guide rail so as to be able to move up and down, and a temporary water receptacle that fits into the guide rail to catch the water flowing through it. 8. A water sprinkling pipe 20 that sprinkles water received by a water receiving plate; a cleaning roller 22 that is impregnated with water sprayed from the water sprinkling pipe and rotates on the wall; a cleaning roller 22 that comes into pressure contact with the cleaning roller to squeeze out the water impregnated in the cleaning roller; Each member of the squeezing roller 24 for removing water and the drainage guide 28 for passing the water squeezed from the cleaning roller into the guide rail again from above is arranged in order from above, and a wiper 31 that slides onto the wall surface above the cleaning roller. It consists of a structure with

E) Function Therefore, the automatic window cleaning device of the present invention has the basic function of cleaning the wall surface with the water-impregnated cleaning roller 22, and further wiping away the moisture remaining on the wall surface with the wiper 31 while the elevator 10 descends. Along with this, the following specific effects occur.

That is, in the automatic window cleaning device of the present invention, water flowing from above into the interior 2 of the guide rail l is received by the water receiver of the elevator 10, and this water is directed onto the cleaning roller 22 by the sprinkler pipe 20. Sprayed and impregnated with cleaning roller 2
2 presses the impregnated part onto the wall surface S of the building by rotation and wipes the dirt with water.Furthermore, the dirty water impregnated in the cleaning roller at this time is dehydrated by the squeezing roller 24, and the squeezed water is removed by the drainage guide 28. A series of actions occurs in which water is passed into the guide rail 1 again.

f) Embodiments Hereinafter, specific embodiments of the present invention will be described based on the accompanying drawings.

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

Here, the guide rail 1 is integrally formed with the sash vertical member S of the curtain wall, has a hollow prismatic cross-section with an interior 2 as a water flow path, and has an elevator lO which will be described later.
A vertical slit 3 is provided on the front surface so that the trolley 12 can be inserted into the interior.

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

FIGS. 1 to 4 are diagrams showing an example of an elevator for an automatic window cleaning device according to the present invention.

This elevator 10 is supported by a guide rail 1 so as to be movable up and down, and here, the platform 11 is supported so as to be movable up and down by fitting the carts 12 located at both ends of the base 11 into the guide rail 1. .

The trolley 12 is provided by bending both ends of the base 11 into a U-shape, and a part of it is fitted into the inside 2 of the guide rail through the slit 3 of the guide rail (8th
(see figure).

On the inside of the guide rail 1 of the bogie 12, there are support rollers 13 that should roll in contact with both sides of the inner wall of the guide rail in the vertical and horizontal directions, and support rollers 14 that should roll in contact and roll in the front direction. Support rollers 15 are provided on the upper side, and on the outside side, support rollers 15 are provided on the lower side to abut against and roll in the front direction of the outer wall of the guide rail.

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

The base 11 supported by the guide rail 1 by the above-mentioned cart 12 includes a water receiver FilB, a water sprinkling pipe 20, and a cleaning roller 22.
, squeeze roller 24, cleaning roller 25, squeeze roller 27,
Each member of the drainage guide 28 is provided in order from the top, and a wiper 31 is provided above the cleaning roller 22.

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

The water receiving plate 1B is made of a plate-like material (rubber is used in this embodiment) with high elasticity and sliding properties and has a planar shape that can be slidably fitted inside the guide rail 1. It is attached like a collar to 12.

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

Therefore, the water receiving plate 18, which is slid into the guide rail like a backing, receives water flowing from above.1. It is connected to the water sprinkler pipe 2 through the communication part 18a and the pipe 19.
It functions to induce the temperature to 0.

The water sprinkling pipe 20 is installed over its entire length above a cleaning roller 22, which will be described below, and has the function of sprinkling water onto the cleaning roller from a large number of nozzles 21 provided therein.

The cleaning roller 22 is made of a material with high elasticity and impregnability (sponge is used in this embodiment) and has a cylindrical shape. By being stopped, the water impregnated by the rotation serves to wipe away dirt from the wall surface (see Fig. 4).

A squeezing roller 24 is pressed under the cleaning roller 22 and functions to squeeze out the dirty water impregnated on the cleaning roller.

In this embodiment, a second cleaning roller 25 and a squeezing roller 27 are further disposed below the cleaning roller and squeezing roller to achieve a more reliable cleaning effect.

That is, the lower cleaning roller 25 cleans the wall surface S with the dirty water squeezed out by the upper cleaning roller 22.

First, the wall S is pre-washed, and then the upper cleaning roller 22 performs the final washing of the wall surface S with clean water.

Incidentally, in this embodiment, the cleaning roller described above is driven by lowering the elevator 10.

That is, the pulley 17 provided on the support roller 15 of the truck 12, the pulley 26 provided on the cleaning roller 25, and the cleaning roller 2.
By connecting the pulley 23 provided at 2 with a belt 32.33, the cleaning roller 25.22 is forcibly rotated by the rolling of the support roller 15 as the elevator 10 descends.

In this case, it goes without saying that the number of rotations of the cleaning rollers 25, 22 is set to be higher or lower than the rolling motion caused by contact with the wall surface S to generate a frictional effect with the wall surface.

Next, reference numeral 28 in the figure is a drainage guide for causing the waste water squeezed out by the above cleaning roller to flow again into the guide rail as waste water.

This drainage guide 28 consists of a tray 29 installed below the cleaning roller 25 over its entire length, and a drainage pipe 30 connected to this tray. By inserting
It serves to flow the water accumulated in the saucer 29 into the guide rail through the drain pipe 30.

Finally, numeral 31 in the figure is a wiper for wiping away moisture remaining on the wall surface S after cleaning by the cleaning roller, and the cleaning roller 2
2.

The elevator 10 having the above configuration is suspended while being supported by the guide rail by a wire W suspended within the guide rail (see Fig. 6), and is installed in a hoisting/unwinding mechanism provided on the roof of a building, etc. (not shown).

In this case, the winding/rewinding mechanism is configured to be movable in the lateral direction, and it goes without saying that the elevator 10 sequentially moves the wall surface in the lateral direction and performs the lifting and lowering interlock each time.

g) Effects of the invention This invention configured as described above has the following effects.

(a) Since the walls of buildings can be automatically cleaned without manual intervention, it is extremely beneficial from the standpoint of preventing fall accidents and streamlining work.

(b) Since the water necessary for cleaning is always sprayed from close to the cleaning roller, economical and efficient cleaning can be performed without any loss unlike in the prior art.

(C) The water mentioned above is passed through the guide rails and taken out from there into the elevator for sprinkling. This eliminates the need for long water hoses as in conventional technology, and reduces the need for building height. It is particularly effective for cleaning skyscrapers.

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

(e) Since the structure is such that cleaning is carried out by lowering the elevator onto the guide rail, no special equipment is required on the building side other than installing the guide rail, and window cleaning equipment is easy to implement.
Moreover, this guide rail can be molded integrally with the curtain wall's sash vertical members, so if it is prepared at the building construction stage, the exterior appearance will not be compromised and the equipment can be constructed economically.

(f) The guide rail supports the elevator and allows water to pass through it, and at the same time serves to accommodate the wire that hangs the elevator, thereby preventing the wire from being swayed by strong winds, etc., thereby realizing safe and reliable operation of the elevator.
