The present invention provides a method for cleaning the upper surface of a vehicle using a top brush that moves up and down according to a pair of guide rails left and right of a guide frame freely swinged and fixed so as to obtain a drooping position on a traveling frame. It relates to a top cleaning device of a vehicle used for.

As the top cleaning apparatus of such a vehicle, what is described in Japanese Patent Laid-Open No. 59-96034 is conventionally known.

When the top cleaning device cleans the vehicle with the top brush while driving the traveling frame, the top brush that comes into contact with the vehicle swings the guide rail by the reaction force received from the vehicle, and detects the swing to move the top brush to the guide rail. The top brush is moved along the upper surface of the vehicle by lifting up and down along it.

By the way, in the conventional top cleaning device, when the top rail is in contact with the vehicle in the guide rail is usually in the drooping position, the guide rail is inclined in the opposite direction to the traveling direction of the traveling frame at the drooping position of the guide rail. Therefore, as the guide rail is inclined greatly, the top brush is raised in a direction approaching the vehicle, so that the surface pressure of the top brush is increased, which makes it easy to cause scratches due to contact friction on the surface of the vehicle.

In order to solve this problem, the sensitivity of the swing detection means for detecting the swing of the guide rail due to the contact between the top brush and the vehicle can be increased to quickly start the rise of the top brush while the swing angle of the guide rail is small. There is a need. However, this causes the top brush to move unnecessarily and cause the top brush to rise unnecessarily due to the imbalance of the top brush or the vibration of the guide rail due to the vibration of the guide rail or the vibration of the guide rail due to the small protrusion of the vehicle or the brush. The problem is worse. In order to prevent this, if the coil spring holding the guide rail in the drooping position is strengthened, the surface pressure of the top brush increases rapidly, and the shape of the front and back is complicated as in these days, and when cleaning a vehicle using a lot of resin parts, The problem arises that the surface of the vehicle is easily scratched by the contact friction of the top brush.

In order to solve this problem, if the driving frame is stopped when the top brush is raised as described in the specification of US Patent No. 3,688,329, the driving frame is frequently stopped during car wash, so that the washing time is also long. .

In addition, since the guide rail for guiding the lifting and lowering of the top brush is pushed by the vehicle in the drooping position, the upper cleaning device described above greatly increases the amount of movement of the top brush in a direction opposite to the traveling direction of the traveling frame according to the swing of the guide rail. I can't take it. Therefore, in order to reduce the washing time by accelerating the traveling speed of the traveling frame, it is necessary to set the rising speed of the top brush early, and as a result, the cleaning effect of the inclined portion of the upper surface of the vehicle becomes worse.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and it is possible not only to increase the cleaning effect by appropriately controlling the surface pressure of the top brush against the vehicle, but also to avoid unnecessary rise of the top brush and unnecessary stop of the traveling frame. An object of the present invention is to provide an apparatus for cleaning a top surface of a vehicle which can shorten the washing time.

In order to achieve the above object, according to the present invention, the guide frame which can obtain a drooping position having a pair of left and right guide rails is fixed to the traveling frame so as to be swingable, and the top brush is lifted and supported in accordance with the guide rails. In the cleaning method of the upper surface of the vehicle to control the lifting of the top brush by the output of the shaking motion detecting means for detecting the shaking of the guide frame according to the contact of the top brush and the vehicle, the guide frame is moved in the traveling frame rather than the drooping position. The guide brush is moved at least at a predetermined angle in the opposite direction from the position in which the guide frame swings in the advancing direction by driving the driving frame by supporting the position swinged in the direction and contacting the top brush with the vehicle. It is a 1st characteristic to raise according to this.

In addition, the present invention is characterized in that, in addition to the first feature described above, the running of the traveling frame is controlled by the output of the swing detection means.

Further, the present invention, in addition to the above-described first or second features, the fluctuation detecting means that the angle toward the traveling direction with respect to the vertical line of the guide frame is equal to or less than a predetermined positive angle (for example, +5 degrees). The third feature is that, upon detection, the top brush is raised and the traveling of the traveling frame is continued.

In addition to the above-described third feature, the present invention provides a saw when the shaking motion detecting means detects that the angle of the guide frame toward the vertical direction is less than or equal to a predetermined negative angle (for example, -5 degrees). A fourth feature is to stop the running of the travel frame at the same time as continuing the raising of the brush.

In addition, the present invention, in addition to the fourth feature described above, the lifting control of the top brush and the traveling control of the traveling frame by the swing angle of the guide frame until the top brush reaches the position for cleaning the ceiling surface of the vehicle. When the brush reaches the position to clean the ceiling surface of the vehicle, the biasing is removed from the guide frame, and the guide frame is set in the free state. It is the 5th characteristic that made it possible to oscillate also.

In addition, the present invention is characterized in that, in addition to the above-described first or second features, the guide is fixed to the position in which the guide frame is rocked in the traveling direction of the traveling frame rather than the drooping position by the inclination means. .

In addition to the fifth aspect described above, the seventh aspect of the present invention is that the guide frame is fixed to a position in which the guide frame is swung in the traveling direction of the traveling frame rather than the drooping position.

In order to achieve the above object, according to the present invention, the guide frame having a left and right pair of guide rails is fixed to the traveling frame so as to be swingable, and supports the top brush so as to be able to move up and down along the guide rails, and swings the guide frame. A washing apparatus for a vehicle, comprising: a control means for controlling the lifting and lowering of the top brush by an output from a swing detection means for detecting a pressure, wherein the guide frame oscillates the guide frame in a traveling direction in a traveling frame in a drooping position. Equipped with an inclination means, the guide frame further has a guide frame swing shaft for suspending and fixing the guide frame fixed to the upper end of the guide rail to the running frame, and the top brush lifting drive shaft for driving the top brush up and down It is installed coaxially with the guide frame swing shaft, the control means is in contact with the vehicle of the top brush When the guide frame than is the other way in a position swinging in the traveling direction at least a certain angle the swing detection means detects that the swing, and is configured to control hagekkeum rises along the guide rail to the top brush eighth aspect.

In addition to the eighth aspect described above, the present invention provides the control means when the shaking motion detecting means detects that the angle of the guide frame with respect to the vertical direction of the guide line is equal to or less than a predetermined angle (for example, +5). The ninth aspect of the present invention is configured to raise the top brush and control the driving of the traveling frame to continue.

Further, the present invention, in addition to the ninth aspect described above, if the sensing means detects that the angle in the direction of travel relative to the vertical line of the guide frame is equal to or less than a predetermined negative angle (for example, -5 degrees), The control means may be configured to control the stop of driving of the travel frame at the same time as the rising of the top brush as a tenth feature.

In addition, the present invention, in addition to any of the above eighth to tenth features, the guide frame inclined means can obtain a bias state and a non-tax state, and the top brush reaches a position for cleaning the ceiling surface of the vehicle. Until the guide frame inclined means obtains the bias state, the control means performs the lifting control of the top brush and the traveling frame by the swing angle of the guide frame, and reach the position where the top brush cleans the ceiling surface. The eleventh feature is that the guide frame tilting means sets the guide frame to obtain a non-tax free state.

Next, an embodiment of the present invention will be described with reference to the drawings.

1 to 7 show an embodiment of the present invention, in which FIG. 1 is an overall front view of the car wash, FIG. 2 is an overall side view of the car wash, FIG. 3 is a sectional view taken along line 3-3 of FIG. Figures 5 and 6 show the control contents of the top brush and the traveling frame according to the swing angle of the guide frame, and Figure 7 shows the view of the action.

As shown in FIG. 1 and FIG. 2, the car washing machine has two drive wheels 2, 2 and driven wheels 3 and 4, respectively, in front of and behind a pair of left and right running rails 1 and 1 on the floor. 3) It is equipped with a door-shaped running frame (4) for driving by guiding. The drive wheels 2 and 2 are connected to the driving motors 5 and 5, which are capable of adjusting the rotational speed by an inverter, so that the driving frame 4 is driven by the running rails 1 and 1. Can be reciprocated at any speed in the forward and backward directions.

Both ends of the one top brush lifting drive shaft 6 installed in the left and right directions are freely fixed to the upper part of the traveling frame 4 by a pair of bearings 7 and 7. The guide frame 9 for guiding the lifting and lowering of the top brush 8 for cleaning the upper surface of the vehicle is provided between the left and right pairs of guide rails 10 and 10 and the upper ends of the guide rails 10 and 10. It is equipped with a hollow guide frame oscillation shaft (11) for coupling together. The guide frame swing shaft 11 is coaxially fitted to the outer circumference of the top brush lift drive shaft 6, and is connected to the top brush lift drive shaft 6 by a pair of left and right bearings 12 and 12. Relative rotation is fixed freely.

As a result, the top brush lifting drive shaft 6 is freely fixed to the top brush 4 by the bearings 7 and 7, and at the same time, the bearings 12, ( 12), the swing of the guide frame swing shaft 11 is freely fixed. For this reason, the structure of the drooping fixing part of the guide frame 9 can be simplified compared with the case where the top brush lifting drive shaft 6 is provided outside the guide frame swing shaft 11, and as a result, The height of 4) can be suppressed.

The left and right guide rails 10 and 10 and the traveling frame 4 are connected by a pair of cylinders 13 and 13 as the guide frame inclining means, and the cylinders 13 and 13 are stretched ( I) By driving, the guide frame 9 can be swung in the a direction and the b direction in FIG.

Referring to FIG. 3 together, the guide rails 10 and 10 have a cross-section. It is formed in the shape of a letter, and inside the L-shaped cross section, the guide plate 14 is fixed. The inner wall of the two guide rollers 15, 15 and the guide rail 10 guided between the guide plate 14 and the inner wall of the guide rail 10 on the left and right guide rails 10 and 10. A pair of right and left trolleys 17A and 17B having one guide roller 16 guided to the other is fixed so as to be able to elevate simultaneously with each other. The left and right ends of the top brush support shaft 18 are fixed to the left and right bogies 17A and 17B, and the top brush rotary shaft 19 of the top brush support shaft 18 is freely fitted with rotation thereof. The sprocket 20 provided on one side and the sprocket 22 of the top brush rotation motor 21 provided on the trolley 17B on the one hand are connected via the chain 23, and the top brush 8 rotates by this. Driven.

The drive frame 4 is provided with a top brush lift motor 24 whose rotation speed is adjustable by an inverter gear, and the sprocket 25 and the top brush lift drive shaft 6 of the top brush lift motor 24. The sprocket 26 at one end of the) is connected to the chain 27. In addition, two sprockets 28 and 28 provided on the top brush drive shaft 6 inside the guide rails 10 and 10 and two at the lower ends of the guide rails 10 and 10 are provided. The chains 30 and 30 are wound between the sprockets 29 and 29 so that both ends of the chains 30 and 30 are connected to and fixed to the trolleys 17A and 17B. In addition, in order to facilitate assembly, the diameters of the sprockets 28 and 28 may include the inner diameter of the guide frame swing shaft 11 and the guide rails 10 and 10 on which the bearings 12 and 12 are mounted. It is formed smaller than the end opening.

Thus, when the top brush lift motor 24 is driven, the top brush lift drive shaft 6 rotates, and the left and right bogies 17A and 17B supporting the top brush 8 are guide rails 10. , As shown in (10), get on and off. At this time, the rubber plates 31 and 31 having a slit are installed to be installed on the opening surfaces of the guide rails 10 and 10 so that the washing water does not enter the guide rails 10 and 10.

The top brush 8 descends by gravity on the chain 34 wound around the sprocket 32 provided on the other end of the top brush lift drive shaft 6 and the sprocket 33 provided on the lower portion of the travel frame 4. Counterweight 35 against the force to be fixed is fixed.

One of the guide rails 10 of the guide frame 9 is provided with an upper limit detection switch 37 of the lower limit detection switch 36 for detecting the lower limit position and the upper limit position of the top brush 8, respectively. The switches 36 and 37 are operated by the magnet 38 provided in one cart 17A. The rotary encoder 39 is installed on one side of the top brush lift drive shaft 6, and the number of output pulses of the rotary encoder 39, which has been transmitted since the upper limit detection switch 37 is in the non-operational state, is operated. By the addition and subtraction, the lifting position of the top brush 8 is detected.

The traveling frame 4 is provided with a pair of stoppers 40 and 41 for restricting the swing end of the guide frame 9. The traveling frame 4 is provided with a forward vibration detection switch 42 and a rear vibration detection switch 43 corresponding to each stopper 40, 41, and the guide frame 9 vibrates in the direction of arrow a. The front vibration detection switch 42 is operated by the magnet 44 installed in the guide rail 10, and the guide frame 9 vibrates in the direction of the arrow b. ), The rear vibration detection switch 43 is operated by the magnet 44.

In addition, a drive gear 45 whose relative rotation is freely fixed to the other end of the top brush lift drive shaft 6 is caught by the driven gear 47 of the rotary encoder 46, and the drive gear 45 and the guide rail 10 are fixed. ) Is connected to the pin 48, so that the swing of the guide frame 9 is transmitted to the rotary encoder 46 via the drive gear 45 and the driven gear 47. Therefore, from the time when the traveling frame 4 travels, the forward vibration detection switch 42 is in the non-operation state from the operating state, and when the traveling frame 4 returns, the rear vibration detection switch 43 is operated. The rotation angle of the guide frame 9 can be detected by adding and subtracting the output pulse of the rotary encoder 46 from the time when it became inoperative.

In addition, the top frame 52 which is lifted and lowered by the left and right pair of side brushes 50 and 50 and the left and right pair of lifting rails 51 and 51 is opened and closed on the traveling frame 4 by the opening and closing rail 49. ) And a pair of left and right side nozzles 53 and 53 are mounted.

The control device 54 installed in the traveling frame 4 includes a lower limit detection switch 36, an upper limit detection switch 37, a front vibration detection switch 42, a rear vibration detection switch 43, a rotary encoder 39, ( 46. Signals from a detector such as 46) are inputted, and the motors 5 and 5 for driving, the top brush rotating motor 21, and the top brush elevating, which are electricized by these signals and a program stored in advance. The drive of the dragon motor 24 or the like is controlled.

Next, the operation of the embodiment of the present invention having the above-described configuration will be described. Here, the swingable range of the guide frame 9 is in the range of 16 ° in total in the a direction and the b direction at the drooping position, respectively, that is, in the front and rear direction of the vehicle V, respectively.

The traveling frame 4 is stopped at the position 4a of FIG. 4 (a) in which the star art position detection switch (not shown) operates, and the top brush 8 is raised to the upper limit position in which the upper limit detection switch 37 operates. The cylinders 13 and 13 are extended and driven, and the guide frame 9 is rocked in the ascending direction of the traveling frame 4 (in the direction of arrow a in FIG. 2) to be brought into contact with the stopper 40, and forward The vibration detection switch 42 stops at the position where it operates. In this state, when the star art button not shown installed in the control device 54 is pressed, the top brush 8 rotates in the direction of the arrow and descends. When the top brush 8 descends to the lower limit position at which the lower limit detection switch 36 operates, the traveling frame 4 starts to travel toward the vehicle V. That is, the traveling frame 4 moves toward the vehicle V while the guide frame 9 is rocked in the traveling direction of the traveling frame 4.

Finally, when the rotary encoder 46 detects that the top brush 8 is in contact with the vehicle V and the guide frame 9 is oscillated at a predetermined angle in the direction of the arrow b by the reaction force, the top brush lifting motor ( 24 is driven to raise the top brush 8 along the guide rails 10 and 10. When the swing angle of the guide frame 9 decreases due to the rise of the top brush 8, the aforementioned top brush lifting motor 24 stops, and the rise of the top brush 8 stops. For example, when the forward vibration detecting switch 42 is operating, the swing angle from the dropping position of the guide frame 9 to the arrow a direction is 8 °, and the swing angle from the dropping position to the arrow a direction is When it is 5 degrees or less, the top brush 8 starts to rise, and when the swing angle from the drooping position to the arrow a direction becomes 5 degrees or more, the rise is stopped. Further, when the swing angle in the direction of the arrow b is lower than -5 ° beyond the lower position, the traveling frame 4 stops running (see FIG. 5). Thus, the bonnet surface and the windshield surface of the vehicle V are cleaned by the top brush 8 while the top brush 8 is repeatedly raised and stopped in accordance with the swing angle of the guide frame 9.

When the traveling distance of the traveling frame 4 becomes a predetermined distance L, which is set in advance, and the top brush 8 reaches the ceiling surface of the vehicle V (position 4b in FIG. 4 (a)), the cylinders 13 and 13 Is in an inoperative state, and the guide frame 9 is freely swingable around the guide frame swing shaft 11. The running value of the travel frame 4 can be obtained by adding or subtracting a pulse output by a rotary encoder (not shown) connected to the travel motors 5 and 5.

When the cylinders 13 and 13 are deactivated, the guide frame 9, which rotates in the direction of the arrow, receives the guide frame 9 from the ceiling surface of the vehicle V, and the guide frame 9 swings in the direction of the arrow b rather than the drooping position. It will be in the state shown by 4c of FIG. 4 (b). After the cylinder 13, 13 is deactivated, the swing angle in the direction of arrow b of the guide frame 9 after a certain time has elapsed may be within a certain angle range (for example, 2 ° to 5 °) at the drooping position. At this time, the top brush 8 stops raising and lowering, when the top brush 8 is above a certain angle (for example, 5 ° or more), the top brush 8 is raised. When the top brush 8 is below a certain angle (for example, 2 ° or less), the top brush 8 is lowered. Let's do it. For this reason, the top brush 8 wash | cleans the ceiling surface of the vehicle V (refer FIG. 6).

When the top brush 8 reaches the rear glass of the vehicle V, the swing angle of the guide frame 9 is 2 ° or less, so the top brush 8 descends while cleaning the rear glass surface. When the top brush 8 reaches the trunk surface and the swinging angle of the guide frame 9 becomes 2 ° or more, the top brush 8 stops descending and cleans the trunk surface. When the top brush 8 reaches the rear end of the trunk surface and the swing angle of the guide frame 9 is 2 ° or less, the top brush 8 is lowered to the lower limit position.

In FIG. 6, when the swing angle is 2 ° or less and the top brush 8 is lowered, load detection means such as a current detector for detecting the current flowing through the top brush rotating motor 21 is a top brush. If it is detected that the load of the rotating motor 21 exceeds a predetermined value, it can control by appropriate surface pressure by stopping the fall of the top brush 8. The lowering stop of the top brush 8 can be performed even when the top brush 8 has reached the front end of the bonnet surface when the traveling frame 4 returns.

Then, when the traveling frame 4 reaches the position 4d in FIG. 4 (b), the traveling stops and the top brush 8 is reversely rotated, and the cylinders 13 and 13 are contractively driven to guide the frame 9. ), The guide frame 9 abuts on the stopper 41, and stops at the position where the rear vibration detection switch 43 operates. Subsequently, the upper surface of the vehicle V is washed while the traveling frame 4 is looped back and the same operation as in the previous traveling step is performed. That is, the traveling frame 4 returns to the vehicle V in a state in which the guide frame 9 is rocked in the traveling direction of the traveling frame 4 in advance.

Until the traveling frame 4 reaches the position 4b in FIG. 4 (a), when the swing angle from the dropping position of the guide frame 9 in the direction of the arrow b is 5 ° to 8 °, the top brush 8 is raised. When the temperature falls below 5 °, the top brush 8 is raised, and when the temperature falls below −5 °, the running of the travel frame 4 is determined. This cleans the trunk surface, the rear glass surface, and the ceiling surface of the vehicle V. When the traveling frame 4 reaches the position 4b in FIG. 4 (a), the cylinders 13 and 13 are inoperative, and after a certain time has elapsed, the direction of the guide frame 9 in the arrow a direction is reached. Stop the lifting of the top brush 8 when the swing angle is between 2 ° and 5 °, and lower the top brush 8 when it is 2 ° or less and raise the top brush 8 when it is 5 ° or more. 8) Clean the ceiling, windshield and bonnet of the vehicle V. Then, when the traveling frame 4 reaches the position 4a in Fig. 4 (a), the looping stops and the washing process ends.

As described above, the cylinders 13 and 13 are extended and driven in the first half of the traveling frame 4 in the ascending manner so that the guide frame 9 is inclined in the arrow a direction, that is, the traveling direction of the traveling frame 4. The top brush 8 which abuts on (V) acts along the guide frame 9 inclined in front of the reaction force received from the vehicle V to facilitate the rise of the top brush 8. Similarly, the vehicle V is caused by shrinking and driving the cylinders 13 and 13 in the first half of the traveling frame 4 during the returning of the traveling frame 4 to incline the guide frame 9 in the arrow b direction, which is the traveling direction of the traveling frame 4. The top brush 8 can smoothly raise the top brush 8 by using the reaction force received by the top brush 8 from the vehicle V. By inclining the guide frame 9 as described above, the top brush 8 can be smoothly raised even when the traveling frame 4 is driven at high speed, so that the time required for washing the car can be shortened.

Further, by inclining the guide frame 9 in the traveling direction of the travel frame 4 in advance, the swingable range of the guide frame 9 can be widened, and the top brush 8 can be smoothly raised. This will be described again with reference to FIG. 7.

7 shows the movement trajectory of the shaft center of the top brush 8 for cleaning the bonnet surface VB, the windshield surface VP, and the ceiling surface VR of the vehicle V in the form of a passenger car when the travel frame 4 is traveling. The solid line shows the present embodiment and the dotted line shows the conventional one. That is, in the present embodiment, the guide frame 9 is inclined 8 ° in the traveling direction of the travel frame 4 in advance, so that the top brush 8 is in contact with the windshield surface VP of the vehicle V, thereby providing the guide frame ( The swing angle of 9) becomes 5 ° from the initial 8 ° minus 3 ° as the dead zone, and the rise of the top brush 8 starts, and the top brush 8 is the ceiling surface VR of the vehicle V. The movement trajectory of the shaft center of the top brush 8 when the traveling speed of the traveling frame 4 and the ascending speed of the top brush 8 are set so that the swinging angle of the guide frame 9 becomes -8 ° when it reaches. This is indicated by the solid line.

On the other hand, in the related art, the guide frame 9 is set at the drooping position (that is, the swing angle is 0 °) and the traveling frame 4 is driven, so that the rocking angle is -3 when the dead band of 3 ° is secured. When it reaches °, the top brush 8 starts to rise. Therefore, if the speed of the traveling frame 4 and the ascending speed of the top brush 8 are the same as in the above example, the swing angle of the guide frame 9 reaches -8 ° which is the swing limit in a short time. (9) is no longer able to swing, and as a result, the trajectory of the shaft center of the top brush 8 is bent as shown by the dotted line.

Comparing them, the trajectory of the present embodiment indicated by the solid line on the right side of the drawing stands at the inclination angle to the part extending to the upper part of the windshield surface VP, whereas the trajectory of the conventional one indicated by the dotted line has the inclination angle lying This indicates that according to this embodiment, the top brush 8 can smoothly pass through the boundary between the windshield surface VP and the ceiling surface VR of the vehicle V. In this way, the guide frame 9 is inclined in advance in the advancing direction to enlarge the swingable range of the guide frame 9, so that the speed of the top brush 8 is increased without increasing the sensitivity of the rotation code 64. The top brush 8 can be smoothly raised without the need to speed up or stop the running of the travel frame 4 frequently, thereby obtaining an effective cleaning effect in a short time.

Further, when the start button is pressed, the cylinders 13 and 13 are contractively driven, and the cylinders 13 and 13 are extended and driven when the rear vibration detection switch 43 is operated. When the top brush 8 is rotated in the direction of the arrow when 42 is operated, the rear vibration detection switch 43, the front vibration detection switch 42, and the rotation encoder 46 as the swing detection means operate normally. Can be diagnosed. As a result, if an abnormality is found, it is possible to prevent the damage of the vehicle or the car wash when the car wash is stopped or the top brush 8 is not used.

As mentioned above, although the Example of this invention was described in detail, this invention is not limited to this Example, A various small design change is possible.

For example, in the embodiment, the guide frame 9 is swung in the cylinders 13 and 13, but other means such as a torque motor may be used instead of the cylinders 13 and 13. In the embodiment, the ascending and returning of the traveling frame 4 are started while the guide frame 9 is swung to a position in contact with the stopper 40 or the stopper 41. With the guide frame 9 in the drooping position at the start of overtraveling, the guide blade 9 is stopped by the stopper 40 after the top brush 8 contacts the vehicle V after starting travel. Or it may be made to rock to the position which contact | connects the stopper 41.

As described above, according to the first aspect of the present invention, the guide frame is fixed to a position in which the guide frame is swung in the traveling direction of the traveling frame rather than the drooping position, and the traveling frame is driven, and the guide frame proceeds by contacting the top brush and the vehicle. The top brush is raised along the guide rail when it swings at least a predetermined angle in the opposite direction from the position swinged in the direction. Therefore, the amount of swing of the guide frame can be increased to the opposite side in the traveling direction of the traveling frame (up to + 8 ° to -8 ° in the practical example). Thereby, the said predetermined angle until raising a top brush can be set large. Therefore, even if the force for fixing the guide frame to the position swinged in the traveling direction of the travel frame is set to a small amount, the swing detection means does not malfunction and the top brush does not reduce the cleaning efficiency of the upper surface of the vehicle without causing unnecessary rise. In addition, since the force for fixing the guide frame to the position swinged in the advancing direction can be set less, there is no fear of damaging the upper surface of the vehicle by the sudden increase in the surface pressure of the top brush.

In addition, according to the second aspect of the present invention, since the travel of the traveling frame is controlled by the output of the swing detection means, the traveling control of the traveling frame can be appropriately performed according to the contact state between the top brush and the vehicle, and the efficiency is good. The vehicle can be cleaned, and the cleaning time is further shortened.

Further, according to the third aspect of the present invention, when the shaking motion detecting means detects that the angle of the guide frame in the traveling direction with respect to the vertical line is less than or equal to a predetermined positive angle (for example, +5 degrees), the top brush is raised. At the same time, since the driving of the traveling frame is continued, the top brush can move in a direction away from the vehicle in contact with the vehicle at the start of the ascending. Moreover, the pressing force against the guide frame by the top brush can act in the direction in which the top brush rises along the guide rail.

Therefore, when the swing amount of the guide frame is also relatively small, the top brush can be moved from the lift stop state to the lift state. Further, even when the traveling frame is driven at high speed, when the top brush contacts the vehicle, the top brush can be smoothly raised along the guide rail. As a result, it is possible to prevent a sudden change in the surface pressure of the top brush and to shorten the washing time of the vehicle.

In addition, according to the fourth aspect of the present invention, when the oscillation detecting means detects that the angle in the direction of travel of the guide frame with respect to the vertical line is less than or equal to a predetermined negative angle (for example, -5 degrees), the top brush rises. By stopping the running of the traveling frame and increasing the amount of swing of the guide frame until the traveling of the traveling frame is carried out, the driving frame is frequently stopped even if the running speed of the traveling frame is increased. It becomes possible to clean a vehicle without work.

Further, according to the fifth aspect of the present invention, until the top brush reaches a position for cleaning the ceiling surface of the vehicle, the top brush is controlled to rise and the travel frame is driven by the swing angle of the guide frame.

The pair of left and right guide rails can keep the top and bottom of the guide brush up and down at all times quickly and reliably even if they are changed by losing or narrowing. Furthermore, since the guide frame can be raised by the swing angle relatively little, even when the side brush is used, the swing structure of the guide frame and the lifting operation of the top brush and the interference with the side brush are avoided. It becomes easy to do this, and it becomes easy to arrange | position these top brush and side brush in a comparatively compact space.

Further, according to the ninth aspect of the present invention, when the shaking detecting means detects that the angle of the guide frame with respect to the vertical direction of the guide frame is equal to or less than a predetermined positive angle (for example, +5 degrees), the control means Since it is configured to raise the top brush and control the running of the traveling frame at the same time, the same effect as the above-described third feature is obtained, and a more reliable cleaning is realized according to the cleaning device for the upper surface of the vehicle.

Further, according to the tenth aspect of the present invention, if the oscillation detecting means detects that the angle of the guide frame to the traveling direction side with respect to the vertical line becomes less than a predetermined negative angle (for example, -5 degrees), the control means Since the top brush is continued to rise and at the same time it is controlled to stop running of the travel frame, the same effect as the fourth feature is obtained. In addition, when a side brush is used together, it does not interfere with the side brush related to excessive fluctuation of a top brush.

Further, according to the eleventh aspect of the present invention, the guide frame inclined means can obtain a biased state and a non-taxed state, and the guide frame tilts until the top brush reaches a position for cleaning the ceiling surface of the vehicle. The means obtains a bias state and the control means controls the lifting and lowering of the top brush and the traveling frame by the swing angle of the guide frame. When the top brush reaches the position for cleaning the ceiling surface, the guide frame tilting means Has been configured to free the guide frame having a non-busy state, so that the same effects as those of the fifth feature described above can be obtained.

In addition, it is possible to regulate and unregulate the guide frame, which is suitable for the cleaning state, as compared with the structure in which the fluctuation is regulated by, for example, a coil spring.
