Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an automatic window cleaning device, and more particularly, the present invention relates to an automatic window cleaning device, in particular, a device in which cleaning devices arranged on the inner and outer surfaces of a window glass or door glass are moved along the glass surface while automatically rotating each other. This invention relates to an automatic window cleaning device for cleaning window glass, etc.

(Prior art) Conventionally, when cleaning the exterior windows of buildings where the windows cannot be opened, a scaffolding board is suspended from the roof of the building using a rope, etc., and a worker stands on this scaffolding board and sweeps by hand. The windows were cleaned by wiping, and a separate worker manually cleaned the inside surfaces of the windows. Some window cleaners have a built-in mechanism that automatically rotates the sweeper, but in this case too, the worker holds the window cleaner in his hand and cleans the interior and exterior surfaces separately.

When cleaning window glass, etc., there is little point in wiping only one side of the glass, and it is necessary to wipe both sides. In order to reduce the work of wiping both sides as much as possible,
There is a glass cleaner that uses the attraction force of a magnet to attract a pair of cleaning tools to each other across a glass surface. For example, the glass cleaner disclosed in Japanese Patent Application Laid-Open No. 53-96264 has a pair of outer casings each housing a magnet, a soft rubber backing plate, and a cleaning medium such as a water-retainable sponge. The opposing homopolar surfaces are made to have different polarities so that they are attracted to both sides of the glass. Japanese Patent Publication No. 53-5
Glass cleaner No. 4867 has a removable sponge exposed in the center of the housing, magnets covered with cloth are installed on both sides, and bombs, brushes, etc. are attached to the ends. These are placed on both sides of the glass so that they stick to each other, and a handle is attached to the back of one of the casings, and by manually operating the handle and moving it along the glass surface, the other casing can be moved to the glass surface. , and clean the inside and outside surfaces of the glass at the same time. In addition, the window glass cleaning tool disclosed in JP-A No. 53-10557 has magnets covered with a soft resin film attached to both ends of a U-shaped holding frame in a flange-like manner, and a sponge is placed inside the U-shaped holding frame from the surface of the magnet. It is housed so that it protrudes slightly,
The window is cleaned by holding the holding frame directly by hand or by attaching a long handle or the like to the holding frame and operating the handle by hand to move the holding frame vertically and horizontally along the glass surface. In addition, as in Japanese Patent Laid-Open No. 56-34323, the window cleaner on the outside of the window glass is configured by detachably attaching a sponge to an iron plate, and the window cleaner on the inside of the window glass is attached to a permanent magnet or an electromagnet with a similar type of sponge. is removably attached and a handle is attached to the magnet, and by moving the inner window cleaner up and down and left and right, the outer window cleaner is also attracted to the inner one and moves in the same direction. or, as in Japanese Patent Application Laid-open No. 47-24171 and Japanese Utility Model Application No. 57-45841, the area around the suction iron piece is Some have multiple balls or rollers attached to them.
There is also a device such as No. 5630 in which a permanent magnet is embedded inside a porous hydrous soft elastic object such as a rubber sponge. All of the above are examples in which the internal sweeper and magnet are fixedly arranged relative to the outer casing, but as in JP-A-48-83658, a magnet equipped with a brush is rotatably housed within the frame. In some cases, the magnet is rotated relative to the frame by an electric motor attached to the frame, and a brushed magnet on the outside of the window glass is driven to rotate. However, in this case as well, the operator manually operates the device frame to move the cleaning device vertically and horizontally along the window glass.

(Problems to be Solved by the Invention) In all of the above-mentioned conventional window glass cleaning devices, the operator must hold the cleaning device on at least one side of the window glass in his hand and manually move it along the glass surface. Naturally, even indoors, high windows require large and strong scaffolding means, and there is a limit to stability, and the scaffolding may shake while the equipment is being moved. It is dangerous, and beginners cannot get rid of their fear. As described above, the conventional device ultimately requires manual window cleaning, which requires time, effort, and skill.

It is an object of the present invention to provide an automatic window cleaning device that can be easily handled even by those who are not particularly skilled in window cleaning, and can automatically clean both interior and exterior window glass and door glass at the same time.

(Means for Solving the Problems) The automatic window cleaning device according to the present invention includes at least one of a pair of cleaning patches in which an annular magnetic sweeper is rotatably housed on the inner circumferential side of the outer magnetic sweeper. The cleaning patches are magnetized to have a magnetic attraction force, and both cleaning patches are arranged so as to face the inner and outer surfaces of the window glass by the magnetic attraction force, and the cleaning patch 1 on one side of the window glass is driven to rotate the annular magnetic sweeper. a device is installed, and a device is provided for moving the cleaning patch on one side along the surface of the window glass, and both of the cleaning patches rotate and move while sandwiching the window glass and being held by adsorption to the window glass. In this way, both the inner and outer surfaces of the window glass can be cleaned at the same time, or in some cases, by operating only one side.

(Example) Next, the present invention will be described with reference to the drawings.

FIG. 1 is a longitudinal cross-sectional view of an automatic window cleaning device according to an embodiment of the present invention, and FIG. 2 is a front cross-sectional view taken along the line ■-■ in FIG. In the present invention, a pair of cleaning patches 2 and 3 are placed on the inside and outside of a window glass 1 to be cleaned, sandwiching the window glass. First, the cleaning patch 2 on the inside of the window glass will be explained. This cleaning patch has an approximately rectangular outer shape and a circular hole in the center.
a member 4 , an annular magnetic member 5 rotatably housed in the inner diameter portion of the outer magnetic member 4 , and an annular magnetic member disposed at the center of the annular magnetic member 5 through a holding frame 15 . and an end plate 9 having a U-shaped cross section and fixed to one side of the outer peripheral side magnetic member 4 and pivotally supporting the rotating shaft 7 via a bearing 8. . The rotating shaft 7 extends outward from the end plate 9 (towards the front toward the window glass), and a pulley 10 is attached to the front end thereof. A small rotary motor 11 is held on the end plate 9, and a transmission belt 13 is stretched between a motor pulley 12 fixed to the output shaft of the motor and a pulley 10 of the rotary shaft 7. A rotational driving force is applied to the rotating shaft 7.

Note that the rotation transmission from the motor 11 to the rotating shaft 7 can be performed by a transmission gear attached to the motor output shaft and the rotating shaft 7, instead of using the above-described means of a boob and a belt. The magnetic members 4.5 each have a non-magnetic holding frame 14.15 with one end open, and a wiping member 16 such as felt mixed with a magnetizing material, soft rubber, or other material used for wiping the glass surface. .17 is filled.

The cleaning patch 3 on the outside of the window glass is also cleaned with the cleaning patch 3 on the inside as described above.
) Wiping members 16', 17'6, such as felt mixed with magnetizing material, have almost the same structure as patch 2 (" They are held on the middle end plate 9', but only the outer cleaning patch No rotary motor is provided on the end plate 9', and the end plate 9'
The rotary shaft 7' supported by the rotary shaft 7' is also not provided with anything like a pulley. The outer diameters or inner diameters of the outer magnetic members 4, 4' and the inner annular magnetic members 5, 5' of the cleaning patch 2.3 on the inside and outside of the window glass are formed to have approximately the same diameter as shown in the figure. The magnetic members of both patches are configured to face each other with the window glass in between.

The cleaning patch 2 inside the window glass is attached to a robot arm. That is, the end plate 9 of the outer peripheral side magnetic member 4 of the patch 2
A spherical bearing block 18 having a concave spherical shaft support hole is fixed to the wrist arm 19.
The spherical end portion of is rotatably fitted. The wrist arm 19 is connected to the robot body 2 through a suitable connecting arm row 20.
1. The robot main body 21 is installed on the floor of the room, and runs on the floor if necessary.
In addition, a control device (not shown) causes the tip paste arm 19 to move evenly over the glass depending on the size of the window glass to be cleaned, for example, as indicated by arrow 2 in FIG.
The robot is set to perform a bellows-like motion from one side of the window to the other, as shown in the figure below.

With the above configuration, cleaning patches 2 on the inside and outside of the window glass,
3 have their respective magnetic members magnetized, so they are attracted to each other by their magnetic adsorption force across the window glass 1, and are held on the window glass surface. In this state, when the rotary motor 11 is driven and the annular magnetic member 5 on the inside of the window glass is rotated around the shaft 7 via the rotating shaft 7, the annular magnetic member on the outside of the window glass is attracted to this. 5' also rotates while remaining in contact with the outer surface of the window glass. This annular magnetic member 5' is pivotally supported by an outer magnetic member 4' through a rotating shaft 7', and the outer magnetic member 4' is attracted to the outer magnetic member 4 inside the window glass. There is no need for co-rotation. If the cleaning patch 2 on the inside of the windowpane is moved over the entire surface of the windowpane 1 by the aforementioned control device and robot device, the cleaning patch 3 on the outside of the windowpane will be moved in the same way, and eventually the cleaning patch 3 on the outside of the windowpane will be moved over the entire surface of the windowpane. The glass surface can be automatically cleaned while the annular magnetic member rotates and moves along the glass surface. In order to prevent the cleaning patch 3 on the outside of the window glass from accidentally falling, it is preferable to connect the end plate of the cleaning patch to a wire suspended from a suitable fixed part of the building with a bend.

FIG. 4 is a longitudinal sectional view showing another embodiment of the present invention.

This embodiment has a double rotary shaft in the center, and one end of the outer cylinder shaft 23 of the double rotary shaft is connected to the rotary motor 11 via a pulley and a belt, and the other end is connected to the inner side through a holding plate 6. It is connected to the holding frame 15 of the wiping member 17. Further, the center shaft 24 of the double rotating shaft is supported by the outer cylinder shaft 23 via a bearing and protrudes from both ends of the outer cylinder shaft 23.
' One end is connected to a drive device 25 with a built-in microcomputer function via a bevel gear 28 etc., and the other end is connected to a caterpillar mechanism 2.
6. This caterpillar mechanism is the window glass 1
It is adsorbed to the glass surface by negative pressure, and is moved along the glass surface by rotation of the central axis 24. Its movement path is controlled by a computer built into the drive device 25, and performs, for example, a bellows-like movement as described in FIG. Negative pressure supplied to the suction cup of the caterpillar mechanism 26 is provided by a hose 27 passing through the central shaft 24 and the like. The rest of the structure is almost the same as the embodiment shown in FIG.

In addition, as a device for moving the cleaning patch of the present invention along the glass surface, for example, a device using the rotational force of a fan can be considered.

(Effects of the Invention) As explained above, according to the present invention, the cleaning members on the inside and outside of the window glass are held on the glass surface using magnetic attraction, and the cleaning member on the inside of the window glass is held on one side, for example, on the inside of the window glass. By rotating and moving the cleaning member on the outside of the window glass, the cleaning member is moved to follow the movement, thereby automatically cleaning the inside and outside surfaces of the window glass at the same time, thereby making it possible to automate and streamline the glass cleaning work.
