Description

[Detailed Description of the Invention] This invention relates to an automatic cleaning device for cleaning the outer wall surface of a building, and particularly relates to an improvement of the squeegee of the cleaning head.

2. Description of the Related Art Conventionally, cleaning devices shown in FIGS. 1 and 2 have been proposed for cleaning surfaces to be cleaned such as exterior walls of buildings, such as window glass and wainscoting.

1 and 2, 1 is a cleaning unit main body, and this cleaning unit main body 1 consists of two wire ropes (not shown) hanging from a roof car (not shown) that runs on the roof surface of a building. It is suspended from a wall surface 4 of the building and is lifted and lowered along the surface 2 of the building to be cleaned, and guide rollers 3 attached to both sides of the surface 2 are suspended from the wall surface 4 of the building.
By engaging with the idle rail 5, the cleaning unit main body 1 can be stably raised and lowered along the surface 2 to be cleaned.

Further, the cleaning unit main body 1 includes a cleaning head 6 for cleaning the surface to be cleaned 2, and this cleaning head 6 includes a pair of cleaning squeegees 8at8b attached to the upper part of the cover frame 7 for sliding the surface to be cleaned 2. , a sealing squeegee 9 attached to the lower part of the cover frame 7, a brush 10 and a cleaning liquid spray nozzle 11 attached to the cover frame 7 located between the sealing squeegee 9 and the cleaning squeegee 8b, and a cleaning head 6. It consists of a flexible side seal 13 attached to the cover frame 7 via a presser plate 12 so as to cover both sides between the squeegees 8a and 9 to improve airtightness inside.

The cleaning head 6 configured as described above is held in the cleaning unit body 1 by a support mechanism 14 such as a link so that it can be moved back and forth, and furthermore, this cleaning head 6 is operated to move back and forth by a head operating device 15 consisting of a pneumatic cylinder or the like. It looks like this.

In the cleaning device configured as described above, when cleaning the surface to be cleaned 2 of a building, the cleaning head 6 is operated by the head operating device 15.
is advanced to press its respective squeegees 8a, 9, brush 10, and side seal 13 against the surface to be cleaned 2.

In this state, the pump built in the cleaning unit body 6 is driven to spray cleaning liquid from the nozzle 11 onto the surface to be cleaned 2, and the wire rope of the roof car is fed out at a predetermined speed to move the cleaning unit body 6 along the guide rail 5. lower it.

Along with this downward movement, the surface 2 to be cleaned moistened with the cleaning liquid is brushed by the brush 1, and is further rubbed and drained by the cleaning squeegees 8a and 8b, thereby cleaning the surface 2 to be cleaned.

Further, the cleaning liquid used for cleaning the surface to be cleaned 2 is recovered by evacuating the inside of the head 6 with a pump.

However, if there is no frame around both sides of the surface to be cleaned that also serves as a seal for the cleaning head, and there is a wall surface 4 directly, the length of the cleaning head 6 may be adjusted to avoid interference between the wall surface 4 and the cleaning head 6. is shorter than the width of the surface to be cleaned 2, and a gap d is required between the side surface of the cleaning head 6 and the wall surface 4 as shown in FIG.

Therefore, in order to make it possible to wipe off the portion of the surface to be cleaned 2 corresponding to this gap d, it is necessary to use the cleaning squeegee 8a.
, 8b and both ends of the sealing squeegee 9 must be shaped into a fan shape.

However, such a fan-shaped part A is weaker than other parts, so it is difficult to obtain the necessary sliding force, and especially in the cleaning squeegees 8a and 8b, the fan-shaped part A is weak compared to other parts. There are drawbacks such as the cleaning effect of the surface being rubbed is poor and the need to use additional hand wiping.

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional method.A reinforcing member is provided at least at both ends of the squeegee that cleans the surface to be cleaned by rubbing, thereby increasing the sliding force necessary for cleaning. It is an object of the present invention to provide an automatic cleaning device which is capable of ensuring the above-mentioned conditions and also improving the cleaning effect of the surface to be cleaned.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

FIG. 3 shows an example of a cleaning head in an automatic cleaning device of this invention. This cleaning head 6 is attached to the top of a cover frame 7 with a fixing metal fitting 16, as in the case of FIG. A pair of cleaning squeegees 8
av8b, a sealing squeegee 9 attached to the lower part of the cover frame 7 with a fixing fitting 17, a brush 10 and a cleaning liquid located between the sealing squeegee 9 and the cleaning squeegee 8b and attached to the cover frame 7 with a fixing fitting 18. Furthermore, the open end surface of the cleaning head 6 is covered with a side seal as in FIG. (only one of which is shown in FIG. 3) has a fan shape so that it can rub the peripheral part of the surface to be cleaned 2 in FIG. In this case, reinforcing plates 19a and 19b are arranged in a stacked manner, leaving the edges in contact with the surface to be cleaned, and are fixed by sandwiching their bases in their respective squeegee fixing fittings 16,16.

Further, the reinforcing plates 19a, 19b are made of a flexible material such as spring steel or stainless steel plate, and have a bottom shape.
The sliding force necessary for cleaning the surface to be cleaned is generated at both end portions of the cleaning device, especially at the weak fan-shaped portion A.

Note that the cleaning head 6 having the above configuration is assembled to the cleaning unit main body 1 in the same manner as shown in FIG.

With this configuration, the cleaning squeegee 8
The sliding force of the fan-shaped portions A at both ends of a and 8b on the surface to be cleaned increases, and the cleaning effect of the fan-shaped portions A on the surface to be cleaned is exerted in the same way as with other parts.

FIG. 4 shows another embodiment of the cleaning head according to this invention, in which the same parts as in FIG. 3 are denoted by the same reference numerals and their explanation will be omitted, and only the different parts will be explained.

That is, reinforcing plates 19a and 19b that provide the necessary sliding force to the cleaning squeegee are integrally molded into both ends of each cleaning squeegee 8a and 8b.

This embodiment also provides the same effects as in FIG. 3, and is suitable for cases where the reinforcing plates 19a, 19b interfere with buildings or cannot be accommodated in the cleaning head.

In the embodiments shown in Figures 3 and 4 above, the reinforcing plates are provided only at both ends of the cleaning squeegee, but the invention is not limited to this, and the reinforcing plates can be provided over the entire length of the cleaning squeegee. It may also be provided.

Further, it goes without saying that the reinforcing plate may be integrally formed using a cover frame or a squeegee fixing fitting.

As described above, according to this invention, reinforcing members are provided at least at both ends of the squeegee that rubs and cleans the surface to be cleaned, and this allows the squeegee to generate the rubbing force necessary for cleaning. Even with a weak cleaning squeegee, the cleaning effect on the surface to be cleaned can be improved, especially the cleaning effect on both sides corresponding to the fan-shaped part of the squeegee, and there is no need for hand wiping, which can also reduce costs. It has the effect of
