The present invention relates to a large-size automatic car wash, and more particularly, a pair of vertical washing brushes disposed on both sides of the vehicle can be selectively moved in the width direction of the vehicle so as to wash the front and rear of the vehicle. It's about a large automatic car wash.

In general, a car wash is a device that performs a car wash on the upper and side surfaces of a vehicle while rotating a plurality of washing brushes installed in a horizontal and vertical direction by a driving device, and is generally classified into a fixed type and a movable type.

Here, the fixed type is to wash the car while passing through the main body fixedly installed on the ground, the mobile type is a device for performing the car wash operation by moving the main body before and after the vehicle is stopped.

1 to 2 is a view showing a mobile car wash according to the prior art, the car wash is to be installed in the main body 100 and the main body 100 is installed a variety of components while forming a kind of frame for the vehicle to pass through It consists of a vertical washing brush 200 and a horizontal washing brush 300 for washing the vehicle, and a rail 150 for guiding the main body 100 in the front and rear directions.

The main body 100 includes a pair of vertical frames 110 arranged vertically on both sides at a wide proportional interval of the vehicle, and a horizontal frame 120 connecting the upper ends of the vertical frames 110. One side of the pair of vertical frame 110 is provided with a vertical washing brush 200 for washing the side of the vehicle, the vertical washing brush 200 is a vertical motor 210 fixed to one horizontal frame 120 It is connected and rotated under the driving force. In addition, one horizontal washing brush 300 disposed in the transverse direction is installed below the horizontal frame 120, that is, at the upper end of the pair of vertical frames 110, and the horizontal washing brush 300 is one side. The upper surface of the vehicle is washed by rotating by receiving the driving force from the horizontal motor 310 fixed to the vertical frame 110.

On the other hand, the vertical motor 210 and the horizontal motor 310 for driving the vertical and horizontal washing brush 200, 300 is a structure that is connected to the controller 400 so that the operator can be intermittent. In addition, the main body 100 has a plurality of rollers 130 are rotatably provided at the bottom of the pair of vertical frames 110, the rollers 130 from the roller motor 140 installed inside the vertical frame 110 It is moved along the rail 150 by receiving the driving force is rotated.

At the same time, the horizontal washing brush 300 washes the upper surface of the vehicle. Done.

However, the conventional large size automatic car wash as described above has the disadvantage that it is impossible to wash the front and rear surfaces in the case of a bus which is a large vehicle.

Conventionally, Utility Model Registration No. 20-0195659 (Horizontal and vertical brush driving devices of an automatic car wash) has been proposed in order to solve this problem.

However, the conventional central mobile automatic car wash has the following problems since the pair of vertical soles are collected in the center.

First, large vehicles such as buses have different protruding positions of side mirrors provided on both sides of the front of the vehicle, especially in the case of side mirrors installed on the side where doors for boarding are installed, protruding about 50 cm to 100 cm in front of the vehicle. It is supported by an arm that is structurally impossible to flow.

Therefore, when the pair of vertical brushes according to the prior art moves to the center of the vehicle, smooth washing is difficult due to the protruding side mirrors, and when the side mirrors and the vertical brushes are in close contact, the side mirrors and the vertical brushes are damaged. In order to prevent this, when the car wash is performed in a position where the vertical brush does not come into contact with the side mirrors, the gap with the front of the vehicle becomes too wide, resulting in a problem that the car wash is not performed.

Second, when the pair of vertical brushes according to the prior art contact each other, the raising of each of the vertical brush is tangled with each other and the impact caused by the contact causes damage to the device, the pair of vertical brushes do not touch each other It is designed to move to the center only to the non-positioned position. For this reason, an untreated area is formed in the middle of the front or rear of the vehicle, and as a result, a person manually cleans the middle of the front and rear of the vehicle corresponding to the untreated area There was an uncomfortable problem to be given.

The present invention was devised to solve the above problems, and the object of the present invention is to allow one vertical cleaning brush of a pair of vertical cleaning brushes to wash the front or side of the vehicle so that the vertical cleaning brush and the protruding side mirror are It is to provide a large automatic car wash that can ensure stable car wash performance by solving car wash defects caused by position interference with the car and preventing unwashed areas from occurring.

The controller (c), like the controller (c) installed in a conventional car wash, controls various horizontal cleaning brushes (6) and vertical washing brushes (7) and (7 ') and washing water nozzles, although not shown. . On the other hand, the controller (c) of the present invention detects the progress of the vehicle in real time through a plurality of sensing units (s1), (s2), and (s3) installed in the main body 1 to drive the roller motor 5a. To control.

That is, the sensing units s1, s2, and s3 are types of sensors for sequentially sensing the entry state of the vehicle passing through the main body 1, and as shown in FIG. 1) It is installed in three places with equal intervals on the side.

These detectors s1, s2, and s3 detect the progress of the vehicle passing through the main body 1 in real time and apply a signal to the controller c, and the controller c detects the input. The driving of the roller motor 5a is controlled based on the signal. That is, the three sensing units s1, s2, and s3 installed at equal intervals on the main body 1 each include a light receiving unit and a light emitting unit. Will be delivered.

In the first case, the sensing unit s3 detects a passing state of the vehicle and transmits it to the controller c. Then, the controller c decelerates the speed of the main body 1 primarily because the sensing unit s3 located at the front end of the traveling direction passes through the vehicle, and then a roller motor when a passing signal is input from the sensing unit s2. The control signal is sent to (5a) to perform the second deceleration. Finally, when a signal is input from (s3), the control unit applies a control signal to the roller motor 5a so that the main body 1 can be stopped after a predetermined time by anticipating the position where the main body 1 completely departs from the vehicle.

On the other hand, when the main body 1 moves forward again in the state of moving to the rear as described above, it is possible to realize by performing the above-described detection and control process in reverse.

Referring to the operation of a large automatic car wash according to the present invention configured as described above are as follows.

First, when the car to be washed enters the main body 1, the main body 1 moves forward and backward of the vehicle along the rail 4, using the horizontal washing brush 6 and the vertical washing brush 7, 7 '. Thus, car washes are performed on the upper and side surfaces of the vehicle, which is similar to the operation process of a conventional car wash. The present invention is to perform the next car wash operation in the state of car wash or car wash is completed as described above.

That is, a large automatic car wash of the present invention is a pair of vertical washing brush (7), (7 ') is selectively moved in the width direction of the vehicle to wash the front and rear of the vehicle.

More specifically, as shown in FIG. 10, when washing the front of the vehicle while the main body 1 is located in the front of the vehicle, the roller motor 5a of the main body 1 is kept in a stopped state. The first driving motor 41 of the driving device rotates in one direction to pull the left moving body 30 in the right direction. At this time, since the vertical motor 7a installed in the left movable body 30 maintains a driving state, the vertical washing brush 7 washes the front of the vehicle, and the left movable body 30 moves to a limit position. When it reaches to the first drive motor 41 is rotated in the reverse direction to return the left moving body 30 to the left position. Here, although not shown, a method of setting the movement limit positions of the movable bodies 30 and 31 is provided to limit driving (not shown) at both ends of the guide rails 20 so as to control driving by contact. It may be set through the drive time control according to the moving distance of the drive motor (41, 41 ').

Meanwhile, even when the front surface of the vehicle has a predetermined inclination angle in the process of washing the front surface of the vehicle as described above, the movable body 30 rotates as shown in FIGS. 7 to 8, resulting in the vertical washing brush 7. ) Performs the car wash while rotating by the inclination angle of the vehicle.

FIG. 11 is a view schematically illustrating a process of washing a rear surface of a vehicle, and washing is performed through the same process as in FIG. 10. However, when washing the rear of the vehicle, the right moving body 31 is towed to the left, so that the corresponding vertical washing brush 7 'washes, and the vertical washing brush 7 located on the left side of the front of the vehicle is washed. Since the washing was performed, the rear surface of the vertical washing brush 7 'is positioned so that both vertical washing brushes 7 and 7' may be evenly worn.

On the other hand, when the main body 1 moves in the forward and rearward direction of the vehicle, the three sensing units (s1), (s2), (s3) sequentially detect whether the vehicle passes, and thus performs multi-stage deceleration. Stable braking of the main body 1 is enabled.

On the other hand, the present invention is not limited to the embodiments described, it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the utility model registration claims of the present invention.

The large sized automatic car wash constructed and operated as described above enables stable washing of the front and rear surfaces of the vehicle by moving one of the left and right movable bodies in the width direction of the vehicle. Therefore, it is possible not only to wash the front face of the vehicle without interfering with the protruding side mirrors, but also to eliminate the untreated car wash zones generated by the conventional centralized vertical cleaning brush. It provides a useful effect to increase the reliability of the car wash. In addition, since the left and right moving bodies on which the vertical washing brush is suspended are elastically returned to their positions, stable washing is possible even when the front and rear surfaces of the vehicle are inclined. In particular, the controller receives the progress of the vehicle passing through the main body through the sensing unit in real time, thereby stably controlling the stop motion of the main body, which has the advantage of enabling an improved automated large sized automatic car wash.
