The present invention relates to a side brush device in a new vehicle cleaning device.

[0002]

2. Description of the Related Art Conventionally, a pair of side brushes are suspended in a frame movable relative to the vehicle to be washed in the front-rear direction so that the side brushes can be opened and closed in the left-right direction. In the side brush device, the front, rear face and left and right side faces are cleaned by brushing. The pair of side brushes can be oscillated in the left and right directions around a pivot point by a power unit. It is known that the surface can be cleaned efficiently (Japanese Utility Model Laid-Open No. 5-26695 and Japanese Patent Laid-Open No. 3-7).

By the way, in the conventional side brush device, the pair of side brushes can be oscillated in the left-right direction of the frame so that the brushes follow the left and right side surfaces of the vehicle to be cleaned. Although it has the advantage that it can be rotated while making contact with it to efficiently brush and wash those sides, it is difficult to make the brush evenly contact the entire front and rear surfaces of the vehicle, and it is left unwashed at the center of those sides. In addition, since the pair of side brushes are connected to a power unit such as a cylinder and are swingably driven around a pivot portion, the pair of side brushes are shaken so as to follow the vehicle body surface. In order to operate, the power unit and expensive control means for driving and controlling the power unit are required, which not only increases the manufacturing cost, but also increases the failure frequency of the vehicle cleaning device itself to increase the operating rate. There is also another problem that this tendency becomes large when the vehicle washing device is used under severe conditions, especially when it is used outdoors under severe conditions. Of the side brushes is regulated by connecting the power device of FIG. 1, an unreasonable force is applied to the support mechanism when the brush swings, and the smooth swing of the brush is hindered or the support mechanism of the brush is prevented. There is another problem that may cause the breakdown of the.

The present invention has been made in view of the above circumstances, and a pair of side surface brushes are provided on the front and rear surfaces of the vehicle body and the left and right side surfaces thereof without the need for an expensive power unit and its control means. The side surface of a new vehicle cleaning device that can be brush-cleaned efficiently by making it follow the contact surface well, and that there is no unwashed part left in the center of the front and rear surfaces of the vehicle body. An object of the present invention is to provide a brush device.

1 is fixed, and when each moving body 5 reaches the inner end of the guide rail 4, it is operated by the moving body 5 and the side brush B
Can be detected to have reached the inner end of the traveling frame 3.

In FIG. 1, 46 is a control device provided on the front surface of the traveling frame, and 47 is a start switch provided on the control device 46.

Next, the operation of the first embodiment of the present invention having the above construction will be described.

As shown in FIG. 1, when the pair of side surface brushes B is in a free state, each side surface brush B rotates around the pivot pin 18 by its own weight until the brush support member 17 hits the tilt position restricting stopper 45. The outer side, i.e., the lower part thereof, is inclined so that the lower part thereof is on the outer side, and is in an outwardly inclined posture.
It has a V shape when viewed from the front. Side brush B
Moves inward on the guide rail 4 and the roller 42 abuts the inclined cam surface 43 ₁ of the cam member 43, the side brush B
Receives an inward rotating moment around the pivot pin 18 and swings inward until the outer end of the bracket 20 hits the stopper 44, and is held in a vertical posture as shown in FIG.

Next, referring to FIGS. 5 to 7, FIG. 8 will be used to explain the process of brushing and cleaning the front, left and right side surfaces and rear surface of the vehicle V by the pair of side brushes B.

.. The vehicle V to be cleaned enters between the two traveling rails 2 and is stopped, the traveling frame 3 is in the standby position (forward start position), and the pair of side brackets B is shown in FIG.
(A) When the start switch 46 is pressed in the position, that is, the open position, the side brush B starts to rotate in the normal direction (solid line direction in FIG. 8), and the side brush B moves in the closing direction, that is, inward. Then, when reaching the (b) position, that is, the closed position, each side brush B is in the vertical posture as described above (see FIGS. 4 and 5), and the inner end detection switch 4
1 is operated and the traveling frame 3 starts going forward [Fig. 8
(1)].

[0024]. When the pair of side brushes B at the (b) position come to the (c) position on the front surface of the vehicle V due to the traveling of the traveling frame, the guide rail 4 swings, the shake detection switch 31 operates, and the traveling frame 3 moves. After the forward movement is temporarily stopped, the traveling frame 3 is slightly returned (50 to 100 mm) to a position suitable for cleaning the front surface of the vehicle V by the pair of side surface brushes B, as shown by the chain line in FIG. 8 (2). Let me stop. After a lapse of a predetermined time, the pair of side surface brushes B are moved in the opening direction by the extension operation of the cylinder 12 to reach the position (d), and the front surface of the vehicle V is cleaned during that time. In this cleaning state, as shown in FIG. 5, the pair of side surface brushes B take a vertical posture so that the front surface of the vehicle can be cleaned efficiently without being left uncleaned especially in the central portion thereof. Then, when the pair of side surface brushes B moves from the (C) position to the (D) position, the roller 42 moves toward the inclined cam surface 43.
₁ , the side brush B begins to incline outward around the pivot pin 18 due to its own weight from the vertical posture shown in FIG.
The final outward tilted posture shown in Fig. 8 [Fig. 8
(2)].

[0025]. When the pair of side surface brushes B reach the outer end position, that is, the (d) position, the moving body 5 reaches the operation of the outer end detection switch 40, and this detection signal causes the traveling frame 3 to start going forward again and to move to the cylinder. Disable 12 As a result, the pair of side surface brushes B held in the outwardly inclined posture contact the side surfaces of the vehicle V by their own weights, and the side surfaces can be brush-cleaned. At this time, when the vehicle V is a passenger vehicle type, as shown in FIG. 6, and when the vehicle V is a wagon vehicle type, as shown in FIG. Then, the surface can be efficiently cleaned [FIG. 8 (3)].

.. When the pair of side surface brushes B pass the rear end of the vehicle V and reach the inner end position (i.e., (f) position) due to the continuing traveling of the traveling frame 3, the side surface brushes B are brought to the vertical posture again, and the moving body 5 moves. The inner end detection switch 41 is operated, and the traveling frame 3 stops its forward movement by this detection signal [FIG. 8 (4)].

Through the above steps, the brushing cleaning of the front surface and both side surfaces of the vehicle by the pair of side surface brushes B accompanying the traveling of the traveling frame 3 is completed.

.. Next, reverse the pair of side brushes B (see FIG. 8).
After the driving, the traveling frame 3 starts to go backward. When the pair of side brushes B in the closed position reach the (g) position on the rear surface of the vehicle V, the guide rail 4 swings,
After the shake detection switch 31 is activated and the traveling frame 3 stops its backward movement, the traveling frame 3 is slightly moved forward (50 to 100 mm) to a position suitable for cleaning the rear surface of the vehicle V by the pair of side surface brushes B. Let me stop. After a lapse of a predetermined time after the stop, the pair of side surface brushes B are moved in the opening direction by the extension operation of the cylinder 12 to reach the outer end position, that is, the (h) position. When the outer end detection switch 40 operates at this position, the traveling frame 3 starts re-traveling and the cylinder 12 is deactivated, and the side surface of the vehicle V is brushed and washed again by the side surface brush B (FIG. 8).
(5)].

FIG. 9 shows a modification of the first embodiment. In this modified example, the abutting means E of the side brush B formed of the roller 42 and the cam member 43 is slightly different from that of the first embodiment, that is, the inclination of the cam member 43 abutting the roller 42. The height of the cam surface 43 is made higher than that of the first embodiment. As a result, when the pair of side surface brushes B reach the inner end position, as shown in FIG. 10, the pair of side surface brushes B can be inclined further inward from the vertical position and held in the inwardly inclined posture. In this modified example, the central portions of the front and rear surfaces of the vehicle V can be washed more carefully.

Further, another modified example is adopted in the first embodiment. In another modified example, as shown by a chain line in FIG. 1, the guide rail 4 is provided with another pair of detection switches 48 inside the pair of inner end detection switches 41. In these switches 48, the roller 42 has the inclined cam surface 4
3 in _{which 1} is the moving body 5 forward reaching detects that it has reached, the side brush B, by introducing pressurized air to the piston rod 13 of the cylinder 12 is contracted to actuate the cylinder 12 by the detection signal The side surface brush B supports the inward urging force suitable for cleaning the front surface of the vehicle V by increasing the urging force in the closing direction, so that the side surface brush B is in the vertical posture (FIG. 5) or the inclining posture (FIG. 10). ) May be easier to take. After that, when the side brush B is operated in the opening direction, the piston rod 13 side of the telescopic cylinder 12 may be opened.

FIG. 11 shows still another modification of the first embodiment. Also in this modified example, the structure of the abutting means E including the roller 42 and the cam member 43 is slightly different from that of the first embodiment. One bracket 20 of the rocking support member S that supports the pair of side surface brushes B, respectively.
A roller 42 is rotatably supported on the inner end of the bracket 20 via an arm body, and a cam member 43 is fixed to the inner end of the other bracket 20 via the arm body. When it moves in the closing direction and reaches the inner end position, the roller 42 and the cam member 43 collide with each other, and the brushes B thereof are held in the vertical posture as in the first embodiment.

FIG. 12 shows still another modification of the first embodiment. Also in this modified example, the structure of the abutting means E including the roller 42 and the cam member 43 is slightly different from that of the first embodiment. At the inner end of the bracket 20 of the rocking support S that respectively supports the pair of side brushes B, a pair of rollers 42 can be freely rotated in the front-rear direction (direction orthogonal to the paper surface of FIG. 12) via arms. On the other hand, a pair of cam members 43 are fixed to the inner ends of the pair of moving bodies 5 by shifting them in the front-rear direction. When the pair of side surface brushes B move in the closing direction and reach the inner end position, the rollers 42 and the cam members 43 abut each other, and the brushes B are in the vertical posture as in the first embodiment. Retained.

Next, FIGS. 13 to 15 show a second embodiment of the present invention. In the second embodiment, the same components as those in the first embodiment are designated by the same reference numerals.

FIG. 13 is a front view of a part of the side brush device,
14 is a partial vertical cross-sectional view taken along line 14-14 of FIG.
15 is a partial cross-sectional view taken along the line 15-15 of FIG.

A rectangular tubular brush support member 17 of a swing support member S is swingably supported by a pivot support pin 18 at the lower center of a movable body 5 movably supported by a guide rail 4. A side brush B is provided below the brush rotation shaft 19 which is rotatably supported by the support 17.
In the free state of the side brush B, the brush B is held in a vertical posture together with the swing support member S. Between the moving body 5 and the brush support 17, a steady rest S of the side brush B is provided.
s is provided. This steady rest mechanism Ss includes a push plate 50 attached to the moving body 5 via a push force adjusting bolt 52.
And a convex rubber plate 51 fixed to the front surface of the push plate 50.
The protruding end of the rubber plate 51 is brought into pressure contact with one outer side surface of the rectangular tube-shaped brush support 17. This prevents the side brush B from swinging due to a slight external force.

In FIG. 13, when the side brush B moves in the closing direction together with the moving body 5, the roller 42 collides with the inclined cam surface 43 ₁ of the cam member 43 and the side brush B in the vertical posture pivots. The pin 18 is tilted inward and held in an inclining posture.

16 and 17 show a modification of the second embodiment. 16 is a front view of the side brush device, FIG.
7 is a plan view showing the operation.

As shown in FIG. 16, in this modified example, the abutting means E including the roller 42 and the cam member 43 is not provided. Stoppers 54 and 55 for restricting a tilting position are provided at both left and right edges of the moving body 5 via arms to face both left and right ends of the bracket 20, and the bracket 20 abuts against one stopper 45. To regulate the outwardly inclined position of the side brush B, and the brush 20 abuts the other stopper 55 to regulate the inwardly inclined position.

Next, the operation of this modified example will be described with reference to FIG. 17. The control device 46 provided on the traveling frame 3 will be described.
Thus, by controlling the rotation procedure and the rotation direction of the pair of side surface brushes B, each side surface brush B is swung inward so that the front and rear surfaces of the vehicle V can be cleaned without being left behind. That is, as shown in FIG. 17 (1), when the traveling frame 3 reaches a position suitable for cleaning the front surface or the rear surface of the vehicle V, a control signal from the control device 46 causes only one of the side brushes B to move. It rotates in the direction of arrow a so that the side in contact with the vehicle body surface faces from the inside to the outside. As a result, the rotating one side brush B swings inward about the pivot pin 18 (in the direction of arrow b) due to the frictional resistance with the vehicle body surface and changes from the vertical posture to the inwardly inclined posture. The central part can be cleaned thoroughly.

Next, in response to a control signal from the control device 46, the rotation of the other side brush B is stopped and the other side brush B is stopped at the same time as shown in FIG. 17 (2).
Is rotated in the same manner as described above so that the side in contact with the vehicle body surface faces the outside from the inside (direction of arrow a '), and this time the other side brush B swings inward (arrow b'). Direction), and similarly, an inclining posture is taken from the vertical posture to wash the front and rear central portions of the vehicle V. It should be noted that the pair of side surface brushes B may be repeatedly rotated alternately.

Next, in response to a control signal from the control device 46, both side surface brushes B are simultaneously rotated (arrows a, a'directions) and opened (arrows c, c'directions) as shown in FIG. 17C. To move.

In the modified example of the second embodiment shown in FIGS. 16 and 17, the pivot pin 18 of the swing support member S is biased to one side from the rotation axis of the side brush B as in the first embodiment. In this case, the side brush B is in an outwardly inclined posture in its free state, and the alternate rotation of the side brush B in the above direction causes the brush B to generate a reaction force due to frictional resistance with the vehicle body surface. Take a vertical posture or an inclining posture.

Although some embodiments of the present invention have been described above, the present invention is not limited to the embodiments.
Various embodiments are possible within the scope of the invention. For example, in the above-mentioned embodiment, the device of the present invention is applied to the mobile car wash device in which the frame travels, but it is needless to say that it can be applied to the fixed car wash device in which the frame is fixed. Further, in the above-described embodiment, the abutting device including the roller and the cam member has been described, but an abutting device having another equivalent function may be used instead.
