Description

[Detailed Description of the Invention] This invention relates to a stationary vehicle washing device, and an object thereof is to provide a vehicle washing device that can be accessed from both directions.

In conventional stationary vehicle washing devices, vehicles can only enter in one direction, and vehicles cannot enter from the opposite direction. Therefore, there are restrictions on where the equipment can be installed.
The disadvantages were that it was difficult to make effective use of the site, and even vehicles near the exit had to take a detour to reach the entrance.

This invention was made in order to improve the above-mentioned conventional drawbacks, and therefore includes a fountain pipe provided at both entrances and exits of the frame, a detection device provided at both entrances and exits of the frame to detect the entry of a vehicle, and an inside of the frame. A brush that is installed on the vehicle and rotates in contact with the vehicle to clean it, a rotatable brush arm that supports the brush, and a balance weight mechanism that normally holds the brush arm in a state substantially perpendicular to the direction of travel of the vehicle. a drive device which rotates the brush arm in a direction opposite to the vehicle traveling direction in response to a detection signal from the detection device to avoid obstacles of the vehicle, and releases the rotation when the vehicle has entered a predetermined position; The basic feature is that the brush is pressed against the vehicle by the balance weight mechanism.

According to this configuration, fountain pipes are provided at both entrances and exits of the frame, and the detection device detects the direction in which the vehicle is approaching, and the brush is rotated according to the direction of approach, thereby removing obstacles such as the rear view mirror of the vehicle. Vehicles can enter from both directions. In addition, in normal conditions, the brush is pressed by a balance weight mechanism, and the brush is rotated only when a vehicle enters, so the drive device for rotation can be of a relatively simple configuration and does not require precise control. . Also, power consumption is reduced.

An embodiment of this invention will be described below based on the drawings.

FIG. 1 is a horizontal sectional view, and FIG. 2 is a vertical sectional view, where 1 is a frame, 2 is a fountain pipe, and 3 is a brush. This brush 3 is provided so that it can rotate approximately 180 degrees from one entrance/exit A to the other entrance/exit B. 4 is a drive device for rotating the brush 3, and in this embodiment, an air cylinder is used.

The configuration of the brush 3 will now be described in more detail.

As shown in FIGS. 3 and 4, the brush 3 includes a brush body 30 and a brush arm 3 that supports the brush body 30.
1 and a brush rotation motor 32 mounted on the brush arm 31. The brush arm 31 is supported by bearings 33, 33' provided on the frame 1 of the apparatus so as to be rotatable approximately 180 degrees.
An upper support shaft 34 that protrudes from the upper bearing 33 is fixed to the brush arm 31, and an air cylinder lever 35 and a counterweight lever 36 that extend in the opposite direction to the brush arm 31 are attached to the support shaft 34. and is provided. A balance weight 38 that hangs down is connected to the counterweight lever 36 via a pulley 37. Due to this balance weight 38, the brush 3 normally protrudes in the width direction of the device, and a pressing force is applied to the vehicle during car washing. That is, the brush 3 maintains a state substantially perpendicular to the vehicle traveling direction, and the brush 3 is pressed against the vehicle by the force of the balance weight 38.

The drive device 4 is connected to the air cylinder lever 35 and swings the air brush 3 in any direction. As described above, this embodiment uses an air cylinder as the drive device 4. This air cylinder has two air ports 40 and 41, and is configured so that the lever 35 can be driven in any direction.

In order to time the actuation of the drive device 4, the present invention includes detection devices 5 at both entrances and exits to detect the entry of a vehicle. The drive device 4 itself may be controlled manually, or an appropriate control device may be provided in addition to a detection device for detecting the arrival of a vehicle to move the brush 3 in the direction opposite to the direction in which the vehicle arrives. It may be configured to swing automatically. In this embodiment, a phototube and a light receiving tube are provided as the detection device 5 at both the entrances and exits A and B, and a control device (not shown) is further provided to automate the rotating operation of the brush 3. Note that as the detection device, any device such as a pressure sensitive device or one utilizing the Doppler effect can be used.

Further, in this embodiment, the motor 32 that rotates the brush body 30 is a motor capable of forward and reverse rotation, and is controlled by the detection device 5 and the control device to automatically rotate forward or reverse depending on the direction of approach of the vehicle. It is configured as follows.

Next, the operation will be explained.

When a vehicle enters from entrance A, the detection device 5 detects this and sends a signal to a control device (not shown). The control device determines whether the vehicle has arrived at the entrance/exit A or B, determines the driving direction of the drive device 4 in accordance with this, and drives the vehicle in that direction. Since this embodiment uses an air cylinder, air port 4
Air is sent and driven by a compressor or the like to either 0 or 41. Since the vehicle has now arrived at the entrance/exit A, the drive device 4 rotates the brush 3 so that it faces toward the entrance/exit B. Also, the brush body 30
The direction of rotation is similarly determined by the control device.

When the vehicle moves through the device and stops at a position where the rear view mirror has passed the brush body 30, the drive device 4
Make it free. This operation may be performed manually, a timer or the like may be used, or the control device may be provided with this function. This makes it possible to effectively avoid obstacles such as the back mirror of a vehicle.

When the drive device 4 becomes free, the brush 3 tries to return to its original state due to the weight of the balance weight 38, so that it is pressed against the vehicle with an appropriate pressure.
Immediately before this, rotate the brush main body 30 and
Clean by squirting water.

During this time, the vehicle is slowly moved forward, and when the vehicle passes entrance/exit B, the rotation of the brush and the water fountain are stopped.
This operation may also be performed manually, or may be automated using the detection device 5 provided at the entrance/exit B and the control device described above.

When the vehicle enters from the entrance/exit B, the brush 3 rotates in the direction of the entrance/exit A, and the direction of rotation of the brush body 30 is reversed. The other operations are the same as above.

Figure 5 shows the rotational movement of the brush 3.a
indicates a case where a vehicle enters from the left direction in the figure, and b indicates a case where a vehicle enters from the right direction in the figure. A and D' are before the vehicle enters, B and C' are when the vehicle is entering, C and B' are during cleaning, and D and A' are after exit.

As described above, the stationary vehicle washing device of the present invention has excellent effects such as allowing vehicles to enter from both directions, so there are fewer restrictions on where the device can be installed, allowing effective use of the site, and eliminating the hassle of detouring vehicles. has.

In other words, according to the configuration of the present invention, fountain pipes are provided at both entrances and exits of the frame, and a detection device detects the direction in which the vehicle is approaching, and the brush is rotated according to the direction of approach, thereby controlling the rear view mirror of the vehicle, etc. Vehicles can enter from both directions as obstacles are avoided. In addition, in normal conditions, the brush is pressed by a balance weight mechanism, and the brush is rotated only when a vehicle enters, so the drive device for rotation can be of a relatively simple configuration and does not require precise control. . Further, there are effects such as reduction in power consumption.
