Next, the operation of the vehicle washing device 1 having the above configuration will be explained.

The streamlined vehicle 2, which is the object to be cleaned in this embodiment, has a streamlined shape extending approximately 5 m from the two tips of the head 2H, and has a driver's cab disposed on the upper surface 2U of the head 2H. Window 2W lower edge 2
As shown in Fig. 9, F is symmetrical about the center line CI- and is about 36
．． Tip 2F of the lower edge of the window on the center line, tilted 5 degrees backwards
a is located 3 m from the vehicle tip 2T.

The vehicle cleaning device 1 of this embodiment is applied to a vehicle 1]i2 having the above-mentioned shape.
Clean the tip 2 downward from a position 5 m from the tip 2T on the side surface 2S of the head 2H, and the tip 2 downward from the lower edge 2F of the driver's cab window on the top surface 2U of the head (3 m from the tip of the head). v42
The lower skirt portion is not to be washed.

First, before vehicle 2 is washed with 1 washing bag and 1 washing bag,
A detergent or the like is applied in advance to the outer panel of the head 2H of the vehicle 2 by a detergent application device (not shown) or the like.

Next, the car! The vehicle type 1i1i2 is input to the control device that controls the vehicle washing device 1. The control device into which the type of shape of vehicle 2 is input is the washing bag r! Calculate the stopping position 1 of the vehicle 2 with respect to 11, that is, the cleaning start position according to the vehicle type,
The vehicle 2 is controlled to move the vehicle li! to a predetermined stopping position between the vehicle washing apparatuses 1.1 and 1.1, as shown in FIG. Stop i2.

After the vehicle 2 has stopped, each brush unit 1 of the vehicle cleaning device 1
5.45 operate almost simultaneously and start cleaning, but the operation of each brush unit 15.45 will be explained individually.

(A) Cleaning by the horizontal brush unit 15 First, the lifting platform I8 of the horizontal brush unit 15 is activated, and as shown in FIG.
), raise the turntable 25. The lift stop position is determined based on a detection signal from a detector provided between the guide rail 17 and the turntable 25 in accordance with the shape of the vehicle 2.

Next, the turntable 25 rotates, causing the rotary brush 39 to extend toward the track 3 side, so that it is positioned at an angle of n2F (approximately 36.5") below the driver's cab window 2w provided above the vehicle head 2H. , the rotating axis of the rotating brush 39 is aligned and stopped.

Next, the tilt angle adjustment motor 29 is activated, and the cylinder body 32 is tilted from the horizontal state to the depression angle direction of approximately 10 inches.
The tip of the rotating brush 39 is set so as to face downward as shown in FIG. 0(a) and FIG. 10(b).

When each angle of the rotating brush 39 is set, the rotating brush 3
9 starts rotating at approximately 136 r, p, m, and at the same time, the trolley 5 starts moving in the direction of the tip 2T of the vehicle 2 (from left to right in the figure). At this time, the sliding surface of the rotating brush 39 does not come into contact with the wiper disposed near the lower edge 2F of the driver's cab window 2W, and the wiper is not damaged by the rotation of the rotating brush 39. The rotating direction of the rotating brush 39 is counterclockwise as shown in FIGS. 10(a) and 10(b), that is, the sliding direction of the rotating brush 39 is in the direction of sweeping out dirt on the sliding surface of the vehicle 2. It is set.

In this embodiment, the truck 5 moves at a constant speed of 3.6 m/mfn. As the cart 5 moves forward, the lifting platform 18 of the horizontal brush unit 15 is controlled to descend at a substantially constant speed, as shown in FIGS. 11(a) and 11(b). In other words, since the rotating brush 39 is controlled to move downward at the tip 2 of the head of the vehicle 2 while keeping the distance between the rotating shaft 4o and the upper surface 2U of the vehicle head 2H substantially constant, the cleaning effect does not change. It is designed so that it can be cleaned without any problems. The control for lowering the rotary brush 39 is operated based on the vehicle type and the traveling speed of the trolley 5, which are input in advance, and a detection signal from a detector provided on the stomach lowering platform 18. In this embodiment, since the upper surface 2U of the head of the vehicle l1i2 is tilted at a substantially constant rate, the descending speed of the elevator platform 18 is controlled to be proportional to the advancing speed of the trolley 5.

As the trolley 5 further advances, the shoulder platform 18 descends and the rotating brush 39 cleans up to the head tip 2T, and when the rotating brush 39 leaves the vehicle 2 at 7 as shown in FIG. Each setting angle is in the initial state, that is, wash/? I
Return to the state before the start and finish the cleaning.

It goes without saying that while the rotating brush 39 is cleaning the vehicle 2, cleaning water is sprayed from the spray nozzle.

According to this horizontal brush unit 15, the upper surface 2U of the vehicle head 2H, as shown in FIG. When viewed from the front of i2, clean the area 45° to the right from the top of the vehicle top surface 2U centering on the two tips of the head.

(B) Cleaning by Vertical Brush Unit 45 First, the dimensions, angles, etc. between the respective members constituting the vertical brush unit 45 of this embodiment described above are set as follows with reference to FIG.

- Length L of the brush arms 64, 65 = 200 cm - Length R of the radius (crank line) of the crank plate 59 = 30 cm - Length BL of the rotating brush 74 = 237 cm - Traveling speed of the truck 5 v' = '3, 6 m/min・The crank MR and the air cylinder 5 when the rotating brush 74 is stored
4 = 76° 47゛ - Distance between the rotation axis 61 and the support shaft 57 at the base end of the air cylinder 54 X = 62.2 cm - Pressure of compressed air sent into the air cylinder 54 Pa = 5k
g/crn' Distance C between the support shaft 57 at the base end of the air cylinder 54 when the rotating brush 74 is stored, the support shaft 57 at the base end of the air cylinder 54 when the rotating brush 74 is stored, and the connecting pin 6o of the piston rod l-' tip 58a = 63 .89 m Also, 5 m from the two tips of the vehicle head 2H in Figure 15 (a
), as shown in (b), it is divided into 20 cm intervals and the tip is called TL○, 10 cm is called TLI, 1 m is called TLIO, etc.

First, compressed air is sent to the proximal boat 54a of the air cylinder 54 of the vertical brush unit 45, and the rotating brush 74 starts rotating at approximately 136'r, p, m. Air cylinder 5
4 extends the piston rod 58 with compressed air, and moves the brush arms 64 and 65 to the track 3 via the crank plate 59.
Rotate to the side. Then, as shown in FIGS. 10(a) and 10(b), the rotating brush 74 is brought into sliding contact with the side surface 2U of the vehicle m2H. This is generated by the tg sliding contact pressure of the rotating brush 74 on the vehicle 2 and the torque generated by the air cylinder 54.

The cleaning start position at this time is 5 m from the tip 2T of the vehicle head.
, that is, cleaning is performed from the position T L 50, and the angle a formed between the traveling direction ■ of the trolley 5 and the brush arm 64° 65
is 9° 12'25", and the angle θ between crank ill R and air cylinder 54 is 68.82° 9 rotating brush 74
Length of contact with vehicle 2 BLL = 229 cm (16th
(see figure). The pressing force W of the rotating brush 74 on the vehicle 2 calculated from these values and each of the above-mentioned values is 54.9
kg, and the sliding contact pressure P per unit length of the rotating brush 74 is
is 2.397kg/10cm.

The truck 5 moves to the right at a constant speed V, as shown in FIG. 16, and accordingly, the brush arms 64 and 65 rotate to clean the side surface 2s of the head of the car 1i1i2.

The rotating brush 74 and brush arm 64 due to this cleaning,

A plan view of the state of contact with vehicle 2 at I8 is shown in Figure 15 (a).
), and a front view of the contact state of the rotating brush 74 at each TL value is shown in FIG. 16, and the length (first

Sliding pressure P per unit length of the rotating brush 74 (kg/10
cm), and the calculated value of the angle α (°) between the moving direction of the truck 5 and the brush arms 64, 65 is shown in the table of FIG. 14(a).

As shown in the table of FIG. 14(a), the pressure Pa of the compressed air in the air cylinder 54 is constant and the angle θ between the air cylinder 54 and the crank LS R is decreasing. Pressing force of the rotating brush 74 on the vehicle 2'
W gradually decreases. At the same time, the length BLL of the rotating brush 74 in contact with the vehicle also gradually decreases depending on the shape of the vehicle 2. That is, the sliding contact pressure P per unit length of the rotating brush 74 is approximately constant, the cleaning ability of the rotating brush 74 does not vary, and the cleaning effect remains approximately constant.

However, TL18, that is, the vehicle tip 2T is 1.8
The length of contact of the rotating brush 74 with the vehicle 2 begins to decrease extremely from the position m in the direction of the two tips. This is because the shape near the tip 2T of the head of the vehicle 2 is formed into a sharp shape, and the contact length of the rotating brush 74 does not decrease at a constant rate.
This is because it changes rapidly around 8. Therefore, the sliding contact pressure P per unit length of the rotating brush 74 increases rapidly from the TL 18 toward the two tips. If this sliding contact pressure P increases significantly beyond a predetermined value, it may damage the painted surface of the outer panel of the car W42 or even damage the cleaning device. Therefore, the supply of compressed air to the air cylinder 54 is stopped at the position of TL]8, and from this position, the force due to the natural expansion of the compressed air in the air cylinder 54 is applied as shown in FIG. 15(b). Like brush arm 64,6
5 to rotate. Here, air cylinder 5
The moving distance y from the start of cleaning of the piston in 4 is TL1
With 1 in the 8th place, it is 105.322mm.

FIGS. 15(b) and 16 show the state of contact of the rotating brush 74 with the vehicle eli2 from TL18 to TL2, and similarly to the above, the rotating brush 74 at each TL value is in contact with the side surface of the vehicle 2. Length of actual contact with 2S BLL (cm

The calculated values of the piston movement distance y (mm) in No. 4 are shown in the table of FIG. 14(b).

According to the table diagram of FIG. 14(b), the air cylinder 54
The compressed air inside gradually reduces its pressure Pa, thereby reducing the pressing force W of the rotating brush 74 on the vehicle 2. and,
Due to the sliding contact pressure P per unit length of the rotating brush 74,
maintains a substantially constant value without much variation, and appropriate cleaning can be performed.

As the truck 5 moves forward, the brush arms 64 and 65 turn to the position TL○ (vehicle tip 2T), and as the rotating brush moves forward, the pressure Pa of the compressed air in the air cylinder 54 increases to approximately 2K.
g/crn', and the pressing force W on the vehicle 2 also decreases.As a result, the cleaning effect decreases, and the pressure inside the air cylinder reaches 52kg/crn', that is, the pressure force W on the vehicle 2 also decreases. The moving distance of the piston is 2.5" from the TL18 position (the sound position, in other words, the position where the angle α between the carriage traveling direction and the brush arm is 70" (Fig. 15).
(see b)), supply compressed air at 5 kg/crn' again and gradually increase the sliding contact pressure of the rotating brush 74 until the angle α between the brush arm and the moving direction of the trolley becomes 90'' (cleaning end position). Increase and wash.

As shown in FIGS. 12(a) and 12(b), the angle α between the brush arms 64, 65 and the traveling direction (■) of the trolley 5 is 90.
When the brush arms 64, 65 reach the shock absorber 71, the brush arms 64, 65 stop pivoting.

When the brush arms 64 and 65 stop rotating, the truck 5 moves further, and the rotating brush 74 separates from the car M2,
When the cleaning is completed, the rotation of the rotary brush 74 is stopped, the piston rod 58 of the air cylinder 54 is operated in the retracting direction, and the brush arms 64, 65 are pivoted in the retracting direction and are locked in the retracting position.

Then, the cleaning work ends when the trolley 5 stops.

According to this vertical brush unit 45, the side surface 2S of the vehicle mark portion 2H, as seen from the front of the vehicle M2 as shown in FIG.
The rotary brush 74 cleans a section of about 70° from the line r of 45° on the right side with the head tip 2T as the middle ILII while keeping the sliding contact pressure P per unit length against the vehicle side surface 2S almost constant.

In this way, each of the horizontal brush unit 15 and the vertical brush unit 45? The head portion 2H of the vehicle v42, which is formed into a streamlined shape, is washed. Since each unit 15.45 is connected and mounted on one truck 5, they operate almost simultaneously as shown in FIGS. 10 to 12, and the vehicle w42
It is designed to perform cleaning. In addition, the other car v4 cleaning device 1, which cleans the left half of the car fiIi2, is placed on one side so as not to come into contact with the protruding rotating brush 39.74 while cleaning the one cleaning device 1 mentioned above. After the cleaning device 1 has cleaned about 2 m, that is, in FIG. 11 (
As shown in a) and (b), after moving ahead by about 2 m, cleaning of the vehicle 2 is started in the same manner as the above-mentioned one of the cleaning devices 1, and the cleaning work is performed.

When the head 2H of the vehicle is finished being washed by the set of cleaning devices fI11, the vehicle 2 moves from between the cleaning devices 1 and advances to a finishing water injection device (not shown). Finishing water is then injected onto the vehicle 2.

In this embodiment, the lengths of the brush arms 64, 65 of the vertical brush unit 45, the radius R of the crank plate 59, the length of the air cylinder 54, the turning angle 1 of the brush arms 64, 65, etc. are set as described above. However, these values are not limited to these.

Further, in this embodiment, the cleaning device 1 is composed of one each of the horizontal brush unit 15 and the vertical brush unit 45, but the horizontal brush unit 15 is different depending on the shape of the two heads of the vehicle to be cleaned. It may be configured and supported by multiple units.

In this case as well, a sufficient cleaning effect can be obtained by calculating the inclination angle of the horizontal brush unit and the control of the air cylinder of the vertical brush unit according to the shape of the vehicle in advance and inputting it into the control device. I can do it.

[Effects of the Invention] As explained above, the bonnet cleaning device for a streamlined vehicle according to the present invention includes a vertical brush unit and a horizontal brush unit mounted on a trolley that runs by the side of the vehicle, and the rotation of each brush unit. By extending each brush into the track, it is possible to wash the sides and top of the bonnet (head) of a streamlined vehicle stopped on the track, making it possible to clean the sides and top of the bonnet (head) of a streamlined vehicle stopped on the track. This has the effect of automating the cleaning of the bonnet of streamlined vehicles, which could only be done manually, improving work efficiency and reducing labor.

In addition, in this cleaning device, the rotating brush of the vertical brush unit pivots along the side of the hood of a streamlined vehicle, with almost constant sliding contact pressure. In addition to pre-ordering, the rotating brush of the horizontal brush unit ≦ the shape of the top surface of the vehicle's bonnet. Since the top surface of the bonnet is cleaned at a constant distance, the effect is that the cleaning action of each brush on the vehicle is almost constant at all times.
