(c) The drive wheel on the hanging side of the cleaning machine of the above-mentioned hoist runs on the guide rail attached to the rooftop handrail, or if the handrail is set back due to the building, the guide rail is moved to the outside of the handrail. shall be installed and run to reduce the size of the protrusion at the hanging position of the cleaning machine.

) Both the building cleaning machine body and the hoist can be disassembled and reassembled using only bolts.

(E) The operation of cleaning equipment is determined by the microcomputer based on various information such as input data, and executed.

(f) Two types of FFI heads are installed, one for the main part of the glass window and one for the corners, so that every corner can be cleaned.

(g) Water supply tanks, drainage tanks, etc. shall be of cassette type so that they can be replaced and removed as appropriate.

(b) Operation With such means and configuration, the building window cleaning machine of the present invention and the hoist used therein are controlled by a large amount of data and information input to the microcomputer, so that the operation is easy. It is faster and the accuracy of one work is improved,
One unnecessary mechanical part is omitted, and the device itself is made smaller.

The cleaning machine main body frame, cleaning machine support beam, and each part of the hoist can be easily disassembled, and the water supply and drainage tanks can also be removed in a cassette style, making it easy to transport by one person. It is arranged so that it can be carried to the required location and easily assembled. There is also a hoist for hanging the cleaning machine.

Since the hanging load is supported by the guide rail on the handrail, its extension size is small), and the winch does not need to be located far from the handrail, so it is naturally possible to further downsize the winch. Become.

Furthermore, the two computer-controlled rotating cleaning heads thoroughly clean the glass surface according to the program, and the cleaning liquid is efficiently collected, so that a clean glass surface can always be regenerated.

(0) Example 1 The building window cleaning machine (1)) of the present invention is hung from a hoist on the rooftop as shown in Figure 10, and descends along the wall (A) of building CB. , when the window (W) reaches a predetermined cleaning position, the cleaning device (2), following instructions from the microcomputer-control device mounted on the cleaning machine support beam, cleans the window (W) on its own frame and on the side of the cleaning machine. It is constructed so that it travels in the direction of arrow (Fl) CF over the wood and thoroughly cleans the window glass surface.

The building window cleaning machine (1) of the present invention which operates as described above also carries a housing (5) containing a microcomputer control device and a washing water control device, as shown in FIG.
Furthermore, the cleaning machine support beam (20) holding the cassette type water supply and drainage tanks (46) (46) and the cleaning head section (4) are moved in four directions CF, ) - (F,) up, down, left and right to the desired location. A cleaning machine frame (main 1) containing a horizontally movable frame (29) (29) configured to clean every corner of the window glass surface.
◎ Also, the cleaning machine support beam (20) has a pair of cross members (10) (11
) and a pair of vertical members (12) and (13), the former is equipped with a pair of hanging horizontal member guides (18) and (19), and the latter is fitted with a bolt (15) for cleaning. Machine frame (
A suitable number of mounting holes are drilled into which the longitudinal members (6) and (7) of 21) are screwed.

On the other hand, the cleaning machine frame (21) has a pair of vertical members (6) (

3G) Travel on (31) in the (F,) direction. The cleaning head section (4) mounted on the horizontally moving frame (29) (29) includes a vertically moving frame (35) and has a gear motor.
It is constructed so that it can freely move in the vertical direction (F) and stop at a predetermined position for positioning.

This vertical position movement is carried out by the gear motor as shown in Figure 4.
Depending on the drive of the motor (33), the wire (45) is connected to the pulley (
34) It is carried out by moving it in the directions of arrows F and -F6. These wires (45) and pulleys (34) are attached along the frame of the horizontal movement frame (29).

The cleaning head section (4) is operated by such a mechanism.

It cleans the glass window main part cleaning head (H) and corner cleaning head (H/) attached to it while moving in four directions (up, down, left and right) according to the cleaning program built into the control system's microcomputer. Once the cleaning start point has been selected, the building window cleaning machine (1) of the present invention is moved, for example, to a jet pressing device (49) so that the main body does not move during cleaning. Therefore, it can be brought into close contact with the wall surface (A).

When this close-contact operation is completed, the cleaning head section (j) -> the glass main section cleaning head (H) first approaches the glass surface (W), but this operation is carried out by the geared motor (38) and the shaft. (39
) on the binion rack (48).

The glass window main part cleaning head (H) that has come into contact with the glass surface (W) thus starts cleaning work on this surface, but because the head is circular, it is not possible to clean a part of the glass window corner. Therefore, before finishing the work, use the corner cleaning head (H).
') and continue the remaining cleaning program.

Of course, this cleaning work is performed by cleaning the main part of the glass window.
), the geared motor (37) and shaft (4
Ω) on the pinion rack (48').

In addition, in order to ensure the cleaning operation of the main part of the glass window and the corner cleaning operation, a geared motor (42) and a worm gear (41) are installed on each cleaning head shaft (39) (40).
) is equipped with a rotary disk (36) driven by a gear motor (38) and (37), which conveniently moves one head toward and away from the glass surface, and changes the relative position.
Clean the glass surface (W) from corner to corner without any problems.

On the other hand, the glass window main part cleaning head (H) that performs such a cleaning operation has a motor (69) installed in a cover (75) attached to one end of the shaft (39) by an appropriate means. It includes an interlocking worm gear means, an umbrella-shaped rotating body (71) connected to this means, a plurality of cleaning rubber spatulas (72) attached to this, and a cleaning water supply pipe (73) and a return pipe. It is equipped with a water recovery pipe (74).

In a structure like this -1: The window glass surface to be cleaned (
The cleaning operation W) is performed as follows.

That is, the rubber spatula (72) that first came into contact with the glass surface,
It is rotated in the direction of arrow (Q) by an umbrella-shaped rotating body (71) via a motor (69) and a worm gear (70).

Also, at the same time as the cleaning head starts rotating, cleaning water is supplied onto the glass surface (W) according to the water supply system diagram shown in FIG.

That is, the cleaning liquid in the tank (dt) is
) (Cassette water supply tank (46)) A pump (p) is mixed with the washing water in the water supply tank (46), and is connected to the control device Hotank (S) (see Figures 2 and 3).

It is sprayed from its nozzle via a constant pressure relief valve (V), an aqueous emulator (a), and a water supply hose (43).

The cleaning water sprayed in this way cleans the glass surface (W) using a rubber spatula (72), and then rides on the airflow (.) sucked in by the pump (p) to the L cover (75). and the umbrella-shaped rotating body (71), and the return water collection pipe (7
4) and return water hose (44)), air-water separator (
S) and is collected in a recovery liquid tank (et).

At this time, the water droplets that cleaned the glass surface (W) flow into the collection pipe (74) along with the intake air flow in the direction of the arrow (e), so that they are collected without scattering outside the cleaning head.

When the cleaning of the main part of the glass window approaches the end, the computer control device, which follows a program input in advance, gives an instruction to the corner cleaning head (H') to start the cleaning operation.

The corner cleaning head (H') received this instruction.

As described above, by the action of the geared motor, vision rack, rotating disk, etc. on the cleaning head (4), the glass surface is reached at the cleaning starting point in Figure 11M.

The corner cleaning head (H
) includes a motor (76) and a gear (77) interlocked with the motor (76), similar to the main glass window cleaning head (H), in a cover (84) attached to one end of the shaft (40) by appropriate means.
, a rotating arm (78), a rotating shaft (79), and a rubber spatula (80) connected thereto, and connected to a water supply pipe (81) and a water recovery pipe (82).

The cleaning operation of the corner cleaning head (H') having such a structure is to first drive the motor (76), pull the rotary arm (78) through the gear (77), and rotate the rotary shaft (79). The rubber spatula (80) fixed to is rotated in the direction of arrow Q'.

At the same time as this rotation, the nozzle force of the cleaning water supply pipe (81)
Apply the cleaning solution to the glass surface (W) in the same way as when cleaning the main part of the glass window.
), clean it with a rubber hose (80), carry the washed water droplets on the airflow (g) and return it to the water collection pipe (80).
2) Collect everything. At this time, the rubber spatula (80) rotates 90 degrees and stops.

An abutment rod (83) attached to its outer end contacts the cover (84) as shown at (86) and rotates in the direction of arrow (h).

As this rotation occurs, the rubber spatula (80) also rotates, so that its tip reaches every corner.

Next, move the shaft (40) and corner ff! Head (H
) is pulled away from the glass surface, the rubber spatula (80) returns to its original position (D) under the action of the spring (85),
Its tip is also restored to the corner of section (D).

In this way, each corner is cleaned according to the computer program inputted in advance after cleaning the main part of the glass window, and cleaning of the subordinate windows of the next seats is started.

If the window of this second seat is to be cleaned on the left and right side of the window shown in Figure 1, the hoist (3) will be installed on the rooftop handrail (as described later).
56) Move on the guide rail (55) attached to the top in accordance with the instructions from the computer in the direction of arrow laJ (f), determine the correct starting point for cleaning the main part of the glass window, and start the new next cleaning. Start the cleaning process.

Figures 6 to 8 show a hoist (
3) is shown.

This hoist (3) runs on a guide rail (55) with one drive wheel (53) mounted on a handrail (56) on the roof of the building, and the other wheel (63).

This is a hoist that runs on a different level, that is, a building roof (CB).

The load, that is, the building window cleaning machine (1) of the present invention, is placed on the deaf hoist, as described above, with the steady rest guide (18).
(19) prevents its lateral deflection, and the adjustment screw (2
The horizontal balance is adjusted by the horizontal member horizontal adjustment means consisting of 2) and the screw rotating gear motor (23).
It is hoisted up and suspended by a winch (62) via ropes (16) (68) and pulleys (46) (61).

Its horizontal movement depends on the traverse drive motor (65) on the concave frame (48) on the first handrail side, its drive shaft (66), bevel gear (67), and chain (54)). 5
3) is carried out by the power applied to.

In addition, since the hoist (3) of the present invention is intended for manual transportation, the handrail (56) on the roof of the building is used to make it as light and small as possible. Cover with the guide rail (55).

It is tightened by a holding metal fitting (57) and bolt means (58), and is constructed so that the drive wheel (53) on one side runs on this in an uneven state.

The guide seal (55) is also sized so that it can be easily transported by one person, and uses a joint method that allows it to be added to the required locations one by one. We will use appropriate means to extend the period in a convenient, safe and continuous manner.

Further, in order to balance the suspension of the hoist and the load, the winch (62) is mounted on the opposite side of the guide rail (55) and supported on the horizontal frame of the other traveling wheel (63).

Also, depending on the height of one handrail, the horizontal position of one handrail, and other installation conditions, the relative position of the hoist (3) and the load must be adjusted, so the horizontal sliding pulley support beam (47) and The frame support fitting body (49) is.

It is constructed so that it can be moved horizontally as well as vertically.

Furthermore, the concave frame (48) and the winch frame (65') are integrated with diagonal members (59) and reinforced with cross members (60), and as a safety measure, a rope (64) is attached to the winch frame (65').
) and fixed to a solid support such as a round roof ring.

The hoist (3) of the present application, whose drive wheels are supported on the handrail in this way, has a small protrusion at the hanging position, and the winch mounting position needs to be far away from the handrail in order to balance the load. Since the winch is narrow, the size of the entire winch can be reduced, and it can be used effectively even on rooftops that are narrow due to camping, advertising, etc.

Also, in cases where the handrail is not installed.

By attaching the guide rail to the edge of the building without providing a guide rail on the handrail, the protrusion dimension of the hoist can be minimized.

The hoist (3) of the present application having a structure like this also applies to the building window cleaning machine (
