DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device suspended from a suspending device disposed above a building so that the cleaning device can be lifted and lowered via a hanging rope member. The present invention relates to an automatic window cleaning device for cleaning a window.

[0002]

2. Description of the Related Art Conventionally, work such as cleaning a window of a building is performed by:
Automatic devices and manned cages were suspended from a rooftop roof car, etc., and these were lifted and lowered along the outer surface automatically or manually by workers in the cage.
Due to an increase in the window area due to an increase in the height of the building, an automatic window cleaning device that can automatically perform a cleaning operation is increasing in many cases.

FIG. 23 shows an example of such an automatic window surface cleaning device. This is because a cleaning device 800 having a cleaning function mechanism for sprinkling water and wiping it toward a window surface of a building (not shown) is moved up and down along the outer surface by a hanging rope 30 from a roof car (not shown) provided on the roof of the building. The cleaning device 800 is supported so as to be able to automatically clean the window surface while lowering the cleaning device 800.

The cleaning device 800 includes a pair of guide shafts 811 vertically mounted on a frame 810, and a cleaning head 820 having a wiping squeegee 821, a receiving squeegee 822, and a sprinkler (not shown).
2 is configured so as to be movable up and down, the sprinkled window surface is wiped with the upper wiping squeegee 821, and the lower receiving squeegee 822 receives and collects sewage flowing down the window surface.

[0005] Wiping squeegee 821 and receiving squeegee 8
Reference numeral 22 denotes a squeegee 821 which is provided so as to be movable in the front-rear direction (horizontal direction in which it is separated from and contacted with the wall surface to be cleaned) by a front-rear movement motor cylinder 823, and is further slidably provided by a vertical swing motor cylinder 824. , The wiping squeegee 821 includes the lifting motor 8
12, the vertical movement by the vertical movement of the cleaning head 810 with respect to the frame 810, the forward / backward movement operation by the forward / backward movement motor cylinder 823, and the swing operation by the elevating swing motor cylinder 824 are possible.

[0006] Such an automatic cleaning device includes a cleaning device 80.
While lowering 0, water is sprinkled by the sprinkler and wiped with the wiping squeegee 821 to clean the window surface. Usually, a window frame protrudes between vertically adjacent window surfaces,
The wiping squeegee 821 includes a front-rear moving motor cylinder 8.
23, vertical swing motor cylinder 824
And the vertical movement with respect to the frame 810, avoids the window frame and wipes the entire window surface.

More specifically, as shown in the conceptual diagram of FIG. 24, the wiping squeegee 821 indicated by a in the figure moves from the substantially horizontal retreat position to the upper corner (2) of the window surface 2C in an upward position as shown in FIG. The tip is pressed into contact with the lower surface of the window frame 2D and the corner of the window surface 2C (hereinafter, this operation is referred to as window frame following), and the cleaning device 800
After wiping the window surface 2C from the upper part to the lower part by the whole descent, the lower part of the window surface 2C is turned from the horizontal to the lower part near the lower corner part (the corner part of the window surface 2C and the window frame 2D) as shown in FIG. When the tip reaches the lower corner of the lower window surface 2C as shown by d (that is, when the cleaning of the window surface 2C is completed), it retreats as shown by e in the figure.

In this configuration, since the cleaning device 800 usually descends at a constant speed during cleaning, the cleaning head 820 moves upward with respect to the frame 810 during the window frame following operation and the retreat operation, whereby the wiping squeegee 821 is moved. It is designed to offset the decline. In other words, in other words, the cleaning device 90
The cleaning head 820 is movable with respect to the frame 810 such that the cleaning head 820 can follow the window frame and perform the evacuation operation even when 0 is descending.

Electric power to each mechanism of the cleaning device 800 (ie, the lifting motor 812, the pump of the water sprinkler, the motor cylinder 823 for forward and backward movement, the motor cylinder 824 for swinging up and down, etc.) is supplied to the cab tire cable hanging from the roof car. To be supplied via the Internet. The exchange of control signals for each mechanism is also performed via signal cables that are similarly routed.

[0010] Cables for power supply and signal transmission are routed down from take-up reels provided on the roof car side via sheaves, so that the cables are wound and taken up so as not to loosen as the cleaning device moves up and down. It is paid out.

[0011]

However, in the automatic window cleaning apparatus 800 having the above-mentioned conventional configuration, the cleaning head 820 is configured to be movable up and down, so that the mechanism is complicated and the entire cleaning apparatus 800 is large. As a result, there is a problem that the roof car to be suspended also becomes large. 25, the cleaning head 820 is supported by a swingable arm 830, and the cleaning head 820 is swung by the swing of the arm 830.
Although a configuration for raising and lowering the robot has been proposed, a configuration using such an arm mechanism requires coordinate transformation for the lifting and lowering control, resulting in a complicated control unit and high cost.

Further, a cable for supplying power to the cleaning device and a signal transmission cable are bent at the sheave portion and are bent to a small diameter on a take-up reel, and as a result, the cleaning device is moved up and down to open the window surface. There is a problem that the cable is liable to be broken because the cable repeatedly bends and expands every time cleaning is performed.

Further, recently, the cable becomes longer and heavier with an increase in the height of the building, and the cable may be damaged by contact with the building due to the wind pressure, and the winding mechanism may become larger. There was a problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and can be configured to be small, lightweight, and low-cost, and can cause damage such as breakage of a building or disconnection thereof due to power supply and signal transmission cables. It is an object of the present invention to provide an automatic window surface cleaning device that does not have any problem.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a side view showing an entire external configuration of an example of an automatic window surface cleaning apparatus according to the present invention, FIG. 2 is a side view of the cleaning apparatus, FIG. 3 is a front view showing a part of the cleaning apparatus, and FIG. FIG. 5 is a plan view in which a part of the cleaning device is seen through, FIG. 5 is a longitudinal sectional view in which a part of the cleaning device is seen through, and FIG. 6 is a block diagram showing a control system.

The illustrated automatic window surface cleaning device 1 includes a cleaning device 10 having a rectangular parallelepiped shape that is long in the horizontal direction, and is provided as a hanging rope member hanging from a roof car 20 as a hanging device disposed on the roof of the building 2. It is configured to be suspended and supported via a wire rope 30.

The wire rope 30 has its base end wound around a take-up drum 22 mounted on a roof car 20. The take-up drum 22 takes up the wire rope 30 and rewinds it to clean the cleaning device 10. It is designed to be driven up and down.

The cleaning device 10 has hanging wires 11 disposed on the upper surfaces of the left and right ends thereof, and a pair of left and right guide roller mechanisms 12 projecting from the front thereof. The guide roller mechanism 12 is engaged with the guide groove 2B extending vertically in the wall surface 2A of the building 2 so that the cleaning device 10 keeps the distance between the guide roller mechanism 12 and the wall surface 2A of the building 2 constant. To be able to ascend and descend.

The wire rope 30 and the hanging wire 11
As shown in an enlarged view of the relevant portion in FIG. 7, the connecting pin 32 provided at the tip of the wire rope 30 and inserted through a rectangular parallelepiped hanging bracket 31 is connected to the hanging wire 11. This is achieved by communicating the coupling ring 11A at the tip.

The cleaning device 10 is, as shown in FIG.
C is mounted on the roof car 2 with the window surface 2C of the building 2 which is disposed at predetermined intervals in the vertical direction (height direction) with the window frame 2D interposed therebetween.
The cleaning is performed sequentially from the upper floor to the lower floor while avoiding the window frame 2D protruding from the window surface 2C while being driven up and down by the rotation control of the take-up drum 22 of 0 to descend.

The control related to the cleaning operation (the lifting control of the cleaning device 10 by the roof car 20 and the driving control of each mechanism of the cleaning device 10) is performed by the operation panel 23 provided on the roof car 20.
(Shown in FIG. 6) is started by the operator, and each is independently controlled by the control device (roof car control device 90, cleaning device control device 80).
The start information can be transmitted from the roof car control device 90 to the cleaning device control device 80, and the detection information from the sensors provided in the cleaning device 10 can be transmitted from the cleaning device control device 80 to the roof car control device 90.

As shown in FIG. 7, the mutual information transmission between the cleaning device control device 80 and the roof car control device 90 is performed by connecting the arm 21 of the roof car 20 and the cleaning device 10 of the wire rope 30 (hanging wire). The optical communication transceivers 91 and 86 are disposed in the vicinity of the (coupling portion with 11), respectively, and optical communication between the optical communication transceivers 91 and 86 is performed by optical communication. That is, one optical communication transceiver 91 is mounted vertically downward on the end surface of the arm 21 of the roof car 20, and the other optical communication transceiver 86 is attached to the side of the hanging metal fitting 31 at the tip of the wire rope 30. It is mounted correspondingly and the connector 87
Is connected to the control device 80 by a cable 88 connected thereto. With such an arrangement structure of the optical communication transceivers 91 and 86, the wire rope 30 becomes vertical to suspend the cleaning device 10.
The optical axes of 86 can be easily matched with high accuracy.

As described above, since the mutual information transmission between the cleaning device control device 80 and the roof car control device 90 is performed by optical communication, the structure for arranging and winding up the communication cable becomes unnecessary, and the structure can be simplified. By using optical communication, even in an office building in which electromagnetic waves are frequently generated, communication failure is not caused by the electromagnetic waves.

As shown in FIG. 8, the structure of the roof car transceiver 91 is as follows.
1 is supported by the horizontal arm 21 of the roof car 20 via a spherical bearing 93 so as to be swingable in a predetermined amount in all directions, and is slidably fitted on the wire rope 30 on the side surface thereof. The guide 94 may be configured to protrude. According to this configuration, the holder 92 is swingably supported in all directions via the spherical bearing 93 in a swingable manner by a predetermined amount, and the guide is fitted to the wire rope 30. The roof car transceiver 91 is always held parallel to the wire rope 30 in a predetermined positional relationship (that is, vertically). As a result, the horizontal arm 21 of the roof car 20 supporting the roof car transceiver 91 is inclined for some reason. Even in such a case, the optical axis does not shift between the roof car side transceiver 91 and the cleaning device side transceiver 86 provided at the tip of the wire rope 30, and the optical axis always keeps the same state. Is what you can do.

The cleaning device 10 includes a water sprinkling device 40, a squeegee mechanism 50, a sewage recovery mechanism 60, a power supply device 70, and a cleaning device control device 80 for controlling the operation thereof. Will be described in detail.

As shown in the circuit diagram of the water channel system in FIG. 9, the water sprinkling device 40 is composed of two accumulators 41 fixed to the frame 13 of the cleaning device 10 and also serving as a water storage tank. A supply pipe 43 is connected to a nozzle pipe 42 disposed parallel to (ie, horizontal to) the wiping squeegee 51 below the wiping squeegee 51 and a plurality of nozzles 4 are connected to the nozzle pipe 42.
4 are arranged at predetermined intervals toward the front.

Although not shown in detail, the accumulator 41 includes an elastic partition member 4 inside the container body 41A.
1B is provided and formed so as to be separated from the liquid storage chamber 41a and the gas storage chamber 41b. By pressurizing and filling the liquid storage chamber 41a with cleaning water, the gas pressure in the gas storage chamber 41b increases, The stored washing water can be pumped by the gas pressure in the air storage chamber 41b. Note that the number of accumulators 41 is not limited to two.

A valve 45 is interposed in the supply pipe line 42. The valve 45 is opened / closed and switched by a cleaning device control device 80 to spray water from the nozzle 44. In the figure, reference numeral 46 denotes a filling line provided with a check valve for preventing backflow at the inlet, 61 denotes a sewage tank, 62 denotes a sewage pan, 63 and 64 denote residual water draining lines, 65
Is a sewage pipe.

In such a watering device 40, the cleaning water is stored in the accumulator 41 in advance at a predetermined pressure, so that the water can be sprayed from the nozzle 44 without using a mechanism such as a pump that requires power. In other words, the window surface cleaning is performed while descending by storing and accumulating water on the roof and returned to the roof after cleaning is completed, and thereafter, the cleaning operation can be performed by repeating the accumulated water pressure and the cleaning operation.

The squeegee mechanism 50 is a plan view of the mechanism, and FIGS.
As shown in FIG. 12, which corresponds to the BB cross-sectional view of FIG. 10, FIG. 13 which is a left side view, and FIG. 14 which is a right side view, a frame 13 of the cleaning device 10 is provided with a pressing force stabilizing mechanism. The pressing force constant mechanism 100 is provided.
A wiping squeegee 51 is provided on a movable base 101 as a support base member of the front-rear movement pressing force stabilizing mechanism 100 via an elevation swing support mechanism 200, and a receiving squeegee 52 is provided via a receiving squeegee supporting mechanism 300. It is configured.

The front-rear movement pressing force stabilizing mechanism 100 includes a pair of left and right support frame portions 13F as support frames extending horizontally in the front-rear direction of the frame 13 and a front-rear movement base 1
01 is movably mounted, and is configured to be movably driven by a back-and-forth movement motor 102 as a supported back and forth movement drive unit.

The front / rear moving base 101 is a rectangular frame having a planar shape, and linear bearing portions 101A provided on both left and right sides thereof are fitted to linear guide rails 14 provided on both right and left support frames 13F. , Are provided so as to be horizontally movable in the front-rear direction along the linear guide rails 14.

The forward / backward moving motor 102 is a DC servo motor having a brake mechanism and a transmission. A pinion gear 104 is mounted on an output shaft of the motor 102 via an electromagnetic clutch 103 serving as a link breaking means. The gear 104 is parallel to the linear guide rail 14 via the slide base 105 as a pressing base member on the support frame 13F (parallel to the moving direction of the front-rear moving base 101).
Is engaged with the rack gear 106 provided at the bottom. Accordingly, when the electromagnetic clutch 103 is in the engaged state, the pinion gear 104 is rotated by the driving of the longitudinal movement motor 102, and the longitudinal movement base 101 is driven to move. The front-rear movement motor 102 and the electromagnetic clutch 103 are controlled and driven by the cleaning device control device 80. The electromagnetic clutch 103 is normally engaged as will be described in detail later.

The slide base 105 is movably provided on the support frame 13F via a linear bearing 16 parallel to the linear guide rail 14. A gas spring 108 is provided between the slide base 105 and a bracket 107 fixed to the rear end of the back-and-forth moving base 101 as a pressing and urging means. It is movable in the direction parallel to the front and rear movement base 101 (front and rear direction), and is urged forward by the elastic return force of the gas spring 108. Gas spring 10
8 is proportional to the amount of compression, and therefore, the urging force acting on the slide base 105 is
It changes according to the relative position to 3F.

On the outer surface of one (left side in the figure) support frame 13F, four front / rear position sensors 81 (81A, 81A) are provided.
B, 81C, 81D) are supported by the bracket plate 15 and are disposed at predetermined intervals in the horizontal direction, and a front-rear position detecting member 109 is disposed at a position of the front-rear movement base 101 corresponding to the front-rear position sensor 81. The front-rear position sensor 81 is connected to the front-rear position detection member 10.
9 is detected, and the detection signal is input to the cleaning device control device 80.

Each of the front / rear position sensors 81 detects the front / rear position detecting member 109 by the front / rear position sensor 81A, and the front / rear position when the front / rear position sensor 81B detects the front / rear position detecting member 109 by the front / rear position sensor 81B. When the moving base 101 detects the front and rear position detected member 109 by the front and rear position sensor 81C, the front and rear moving base 101 detects the front and rear position detected member 109 by the front and rear position sensor 81D. The cleaning device controller 80 is set to be in the protruding position, and the cleaning device control device 80 uses the detection information of the front and rear position detection member 109 by the front and rear position sensor 81 to move the front and rear movement base 1 with respect to the support frame 13F.
01 (the position of the wiping squeegee 51 in the front-rear direction) can be recognized.

Also, the slide base 105 has a structure shown in FIG.
As shown in FIG. 15 which is a C-C enlarged sectional view thereof,
An operation rod 18A of a linear potentiometer 18 as a pressing base member position detecting means supported by a support frame 13F via a sensor bracket 17 is connected, and an output of the linear potentiometer 18 is input to a cleaning device controller 80, Thereby, the relative position of the slide base 105 with respect to the support frame 13F can be detected. That is, the output voltage of the linear potentiometer 18 changes steplessly in accordance with the position of the operation rod 18A, and the output voltage corresponds to the relative position of the slide base 105 with respect to the support frame 13A. Thereby, the position of the slide base 105 with respect to the support frame 13F can be recognized. As described above, since the urging force of the gas spring 108 changes according to the relative position of the slide base 105 with respect to the support frame 13F, the urging force of the gas spring 108 on the slide base 105 can be determined by the output of the linear potentiometer 18. ing.

The sensor bracket 17 is provided with three pressing force sensors 82 (82A, 82B, 82C) at predetermined intervals in the front-rear direction, and a pressing force detection member is provided at a position of the slide base 105 corresponding thereto. 110 is provided, and detection information of each pressing force sensor 82 is input to the cleaning device control device 80. When the pressing force sensor 82A detects the pressing force detection member 110 by the pressing force sensor 82A, the slide base 105 detects the pressing force detection member 110 by the pressing force sensor 82C. The slide base 105 is set to a proper intermediate position between the limit position on the side and the pressing force sensor 82 </ b> B when the pressing force detection member 110 is detected by the pressing force sensor 82 </ b> B.

Further, an emergency evacuation device 400 is provided on the support frame 13F on the same side as the side on which the front / rear position sensor 81 is provided, as shown in FIG.

The emergency evacuation device 400 includes a weight bracket 402 fixed to the front-rear movement base 101 and a weight wire 402 having an end coupled to the support frame 1.
A weight 404 serving as a retraction urging means is connected to the other end by winding around a sheave 403 provided at the rear end of the 3F, and the longitudinally moving base 101 is always moved rearward by the weight of the weight 404. It is configured to be biased.

The weight 404 is loosely fitted to a vertical guide bar 405 fixed to the frame 13 so as to be movable in the vertical direction along the guide bar 405. Acting as a load on the longitudinal motor 102, when the electromagnetic clutch 103 interposed between the longitudinal motor 102 and the pinion gear 104 is disengaged, the weight of the weight 404 moves the longitudinal base 101 backward. That is what you are going to do. Also, as shown in FIG. 17, a stopper bolt 405 is
Is provided, and a damper 406 is provided at the rear end of the frame 13 of the cleaning device 10 corresponding to the stopper bolt 405. When the movable base 101 moves backward, the stopper bolt 405 abuts on the damper 406. (Ie, the stop position on the rear side of the moving base 101 is determined). The retracting urging means for urging the back-and-forth moving base 101 to move rearward is not limited to the weight and may be constituted by a spring.

The forward / backward moving pressing force stabilizing mechanism 100 constructed as described above is controlled by the cleaning device controller 80 so that the forward / backward moving motor 102 and the electromagnetic clutch 103 are controlled and driven. By driving the pin 102 (rotating the pinion gear 104), the front-rear moving base 101 is moved to the linear guide rail 14.
Along (in the front-back direction with respect to the slide base 105)
Moving. When the forward / backward moving motor 102 stops, the brake mechanism operates to make it impossible to rotate.
01 is immovable with respect to the slide base 105.

Normally, the electromagnetic clutch 103 is always energized and engaged, but in an emergency, the energization of the electromagnetic clutch 103 is turned off and the emergency evacuation device 30 is turned off.
Activate 0. When the electromagnetic clutch 103 is released, the pinion gear 104 is rotatable with respect to the output shaft of the longitudinal motor 102, the longitudinal base 101 is movable, and the emergency evacuation device 400 operates. That is, the front-rear movement base 101 is moved rearward by the weight of the weight 404.

When the front / rear moving motor 102 drives the front / rear moving base 101 to move forward with respect to the slide base 105, and the wiping squeegee 51 supported by the base 102 comes into contact with the window surface 2C to prevent further forward movement, The gas spring 108 is compressed against its elastic restoring force, and the slide base 105 retreats with respect to the support frame 13F. As a result, the wiping squeegee 51 is pressed against the window surface 2C by the elastic restoring force of the gas spring 108. I do.
If the forward and backward movement base 101 continues to be driven forward, the gas spring 108 is further shortened and its elastic return force (that is, the pressure contact force of the wiping squeegee 51) gradually increases. For this reason,
By driving the front-rear movement motor 102, the front-rear movement base 101 (that is, the wiping squeegee 51) can be moved back and forth, and the wiping squeegee 51 is pressed against the window surface 2C by an arbitrary pressing force.
Can be set to be pressed.

Here, as described above, the pressing force sensor 82
The pressing force is set to an appropriate value at the position of the slide base 105 where the pressing force detection member 110 is detected by B. However, from the state where the pressing force is appropriate, the distance between the cleaning device 10 and the window surface 2C is changed. Is changed, the relative position of the slide base 105 to the support frame 13F is changed by the elastic restoring force of the gas spring 108, and the squeegee 51 is kept pressed against the window surface. However, the squeegee 5
The pressing force on the window 1 changes. For this reason, the cleaning device controller 80 is configured to perform the following based on the detection information from the pressing force sensor 82 and the output information from the linear potentiometer 18.
The wiping squeegee 51 is maintained in a proper range of the pressing force by controlling and driving the forward and backward moving motor 102 as described below.

That is, the squeegee 51 is allowed to be pressed against the window surface 2C with an appropriate pressing force (a state in which the pressing force sensor 82B detects the pressing force detection member 110) and the output of the linear potentiometer 18 is used as a reference. Output range of the linear potentiometer 18 corresponding to the moving range of the slide base 105 within the range of the pressing force (upper and lower thresholds)
Is set in advance, and this threshold value is compared with the output of the linear potentiometer 81. If the output exceeds the threshold value, the forward / backward moving motor 102 is pressed by the pressing force sensor 82.
It is driven to move back and forth until B detects the pressing force detection member 110. Note that the allowable movement range of the slide base 105 may be used as the detection signal of the pressing force sensors 82A and 82C. However, by controlling the output range of the linear potentiometer 18 as in the present configuration example, the allowable movement range according to the building is allowed. The setting of the range of the pressing force can be easily changed.

In such a control configuration, the frequency of driving of the front-rear movement motor 102 is small and power consumption is suppressed. If the power supply depends on the storage battery, a long-time operation can be performed, and the cleaning operation can be performed efficiently. Is what you can do.

As described above, the automatic window cleaning apparatus 1 provided with the cleaning apparatus 10 includes a building 2 in which the window surfaces 2C are arranged at predetermined intervals in the vertical direction (height direction) with the window frame 2D interposed therebetween. Cleaning device 10 by controlling the rotation of the take-up drum 22 of the roof car 20 by the roof car control device 90.
Is lowered, and the window frame 2 protruding from the window surface 2C by the cleaning device 10 controlled and driven by the cleaning device control device 80.
Clean from the upper floor to the lower floor, avoiding D.

The cleaning of the window surface by the cleaning device 10 is performed by spraying the washing water from the nozzle 44 of the water spray device 40 toward the window surface 2C, and the sprinkled window surface 2C is lowered by the cleaning device 10 to move the squeegee mechanism 50. This is performed by wiping downward with the wiping squeegee 51, and the sewage flowing down the window surface 2C is received by the receiving squeegee 52 and collected in the sewage pan 62,
The water is stored in the sewage tank 61.

The cleaning operation is performed by the roof car 20 as described above.
The operation is started by an operator operating the operation panel 22 provided in the vehicle, and the roof car control device 90 and the cleaning device control device 80 independently operate the respective mechanisms of the roof car 20 and the cleaning device 10 according to a predetermined program. This is performed by controlling the drive. That is, the roof car control device 90 controls the rotation of the winding drum 22 at a predetermined speed to lower the cleaning device 10 at a predetermined speed, and the cleaning device control device 80 controls the window surface 2C of the building 2 to be cleaned. The sprinkling mechanism 40 and the squeegee mechanism 50 are sequence-controlled in a predetermined procedure based on the arrangement, the width of the window frame 2D, and the amount of protrusion thereof, and during the cleaning operation, the wiping squeegee 51 is The pressing force is maintained within a predetermined range.

Next, the control of the cleaning device 10 by the cleaning device control device 80 will be described in order with reference to FIG. 19 which is a flowchart and FIGS. 20 and 21 which are explanatory diagrams.

Before starting the cleaning, the cleaning device 10
(A) The wiping squeegee 15 is horizontal as shown by a in FIG.
As described above, the front end of the receiving squeegee 52 coincides with the front end of the receiving squeegee 52, and stands by in a state of being retracted from the front surface of the window frame 2D (reference position).

When the start of cleaning is instructed, first, an initialization operation is performed using the wiping squeegee 15 as a reference position (S).
1).

In the initialization operation, the front-rear movement base 101 (that is, the wiping squeegee 15) is once moved backward by the front-rear movement pressing force stabilizing mechanism 100, and then moved forward, so that the front-rear position sensor 81C detects the front-rear position detected member 109. It is positioned at a reference position to be set.

Then, the descent is started under the control of the roof car control unit 90.
(A) As shown by a in the figure, the cleaning device 10 is opposed to the wall surface 2A, not the window surface 2C, and a signal detecting the wall surface 2A from the upper window frame sensor 84 is input to the cleaning device control device 80. .

The cleaning device 20 descends and the upper window frame sensor 8
When the outer frame 4 comes off the wall surface 2A and reaches a position facing the window surface 2C as shown by b in FIG.
(S2), and this position is set to the window surface 2C.
(The lower portion of the window frame: the upper corner portion), and a predetermined window frame following operation is performed based on the amount of protrusion of the wall surface 2A (= the amount of protrusion of the window frame 2D) with reference to this position (S3). FIG.
As shown in (B), the tip of the wiping squeegee 51 is placed on the window surface 2.
Match with the upper corner of C.

The window frame following operation is performed by simultaneously driving the forward and backward movement pressing force stabilizing mechanism 100 and the elevating swing supporting mechanism 200 to swing the wiping squeegee 51 upward at a predetermined speed while moving the wiping squeegee 51 upward at a predetermined speed. Is made to coincide with the upper corner portion of the window surface 2C, and the wiping squeegee 15 is further advanced by a predetermined pressing force by an amount of pressing against the window surface 2C. At this time, the cleaning device 10
Is continuously decreasing at a constant speed, the swing amount is set by adding the descending amount. During this window frame following operation,
Cleaning device 1 controlled by roof car control device 90
The lowering speed of 0 may be reduced to increase the reliability of the operation.

After the window frame following operation, the valve 45 of the sprinkler 40 is operated to sprinkle the washing water from the nozzle 44 toward the window 2C (S4). Is cleaned by wiping with a squeegee 51. Immediately after the window frame following operation, the front-rear movement pressing force stabilizing mechanism 100 starts the window surface 2 of the wiping squeegee 51 as described above.
The control for setting the pressure contact force on C to an appropriate range is started, and functions continuously during the following window surface cleaning process to maintain the pressure contact force of the wiping squeegee 51 on the window surface 2C in an appropriate state.

The spraying of the cleaning water is stopped for a predetermined time (ie, a predetermined amount above the window surface 2C) after the window frame following operation, and the cleaning after that is performed using the cleaning water flowing down the window surface 2C.

Here, the watering time by the watering device 40 is
At the start of the work (at the time of cleaning the upper floor) and at the time of cleaning the lower floor where the work has progressed, the amount of water sprayed per unit time is changed so as to be constant. That is, since the watering device 40 sprays the stored washing water by the pressure stored in the accumulator 41 as described above, the pressure decreases due to a decrease in the water storage amount due to watering, and the watering amount per unit time is reduced. Decrease. As a result, if the water was constantly sprayed on all the windows 2C for a certain period of time, the cleaning work would proceed immediately after the start of the cleaning work as compared to when cleaning the high floor where the pressure in the accumulator 41 was high, and the inside of the accumulator 41 would be cleaned. When cleaning the lower floors where the pressure has decreased, the amount of watering will decrease, so the watering time will be extended in accordance with the expected decrease in pressure with the progress of the cleaning work, and the amount of watering for the unit window surface 2C will be reduced. It is controlled to be constant. Accordingly, if the descending speed of the cleaning device 10 during cleaning is constant, the watering area increases on the window surface of the lower floor.

As shown in FIG. 21A, at a predetermined position where the cleaning portion has approached the lower corner portion of the window surface 2C (the upper surface of the lower window frame 2D) due to the progress of cleaning due to the lowering of the cleaning device 10, and as shown in FIG. A predetermined lying down operation is performed (S6).

The prone movement is performed by swinging the wiping squeegee 51 in the upward posture downward by the elevating swing supporting mechanism 200 to make the horizontal state, and at the same time, the amount of displacement of the front end of the wiping squeegee 51 in the front-rear direction, which is expected due to the swing. It is driven to move forward and backward by the same amount and forward and backward moving pressing force stabilizing mechanism 100.

The start of the lying down operation is set by a timer based on the length of the window surface 2C in the height direction and the descending speed of the cleaning device 10 from the detection of the aforementioned window surface start reference (the lower surface of the upper window frame). (S5). The detection may be performed based on the detection of the upper surface of the window frame 2D by the lower window frame sensor 85.

When the wiping squeegee 51 is in a horizontal state due to the prone operation, its tip coincides with the tip of the receiving squeegee 52 as described above, and thereafter it descends in this posture.

Then, as shown in the enlarged view of FIG. 22, when the front end portion of the wiping squeegee 51 and the receiving squeegee 52 reaches the lower corner of the window surface 2C, the wiping squeegee is fixed by the front-rear moving pressing force stabilizing mechanism 100. 51 is retracted and retracted as shown by b in FIG. 21 (S8). The retraction of the wiping squeegee 51 is performed based on the detection of the upper surface of the window frame 2D by the lower window frame sensor 85 disposed below the receiving squeegee 52 (S7). It may be performed by time management from the time of detection. During evacuation, the lowering speed of the cleaning device 10 controlled by the roof car control device 90 may be reduced to increase the reliability of the operation.

The retraction of the wiping squeegee 51 by the forward / backward movement pressing force stabilizing mechanism 100 is temporarily stopped by the front / back position sensor 81.
B is an intermediate position for detecting the front / rear position detected member 109, and is again an initial setting position for detecting the front / rear position detected member 109 by the front / rear position sensor 81C.

Thereafter, the upper window frame sensor 84 detects the next window frame 2
When the lower surface of D (the starting point of the window surface 2C) is detected, the above steps are sequentially repeated a predetermined number of times (S9), and the operation is completed by reaching the lowermost window surface.

Here, the wiping squeegee 51 is not retracted by the back-and-forth moving pressing force stabilizing mechanism 100 for some reason, and the receiving squeegee 52 located below the wiping squeegee 51 by the lowering of the cleaning device 50 causes the window frame 2 to move.
In the case of interference with the upper surface of D, the sewage pan holder 303 supporting the receiving squeegee 52 swings upward and is detected by the contact sensor 308, and the roof car controller 90 uses the detection signal to lower the cleaning device 10. Is stopped, and the electromagnetic clutch 1
The emergency evacuation device 400 is operated by turning off the power supply to the power supply device 03. Thereby, the moving base 101 (wiping squeegee 5)
1 and the receiving squeegee 52) are retracted to the rear side to prevent damage to the squeegee mechanism 50 and the building 2 (window frame 2D).

In the upward position so that the tip thereof matches the upper corner of the window surface, and based on the position of the pressing base member by the pressing base member position detecting means. The driving device moves forward and backward to maintain the pressing biasing force of the pressing biasing unit within a predetermined range, and the wiping squeegee is moved before the tip of the wiping squeegee member reaches the lower corner of the window surface by the lowering of the cleaning device. The wiping squeegee member is retracted when the tip of the wiping squeegee member reaches the lower corner portion by reciprocating the wiping squeegee member, so that the wiping squeegee member can be retracted and retracted without using a mechanism for moving the cleaning head up and down. The operation can be performed, and the entire cleaning device can be configured to be small and lightweight by simplifying the mechanism. As a result, the roof car can be reduced in size, can be reduced in size as a whole, and can be configured at low cost.
