Description

Automatic car wash system using cloth brush {AUTOMATIC CAR WASHING MACHINE SYSTEM USING CLOTH BRUSH}

The present invention relates to an automatic car wash system, and more particularly, to an automatic car wash system using a roll type cloth brush to improve cleaning power for a vehicle.

In general, the automatic car wash system mainly uses a single, multi-strand, solid brush. The automatic car wash system cleans the vehicle by rotating the brush while spraying detergent and car wash water onto the vehicle, but there are problems such as scratching the surface of the vehicle to be cleaned by the rotating brush. In addition, these brushes are easily worn due to frequent contact with the surface of the vehicle, and when rotating at high speed, the fiber strands of the brush are broken, that is, damaged when the vehicle rotates. Since the brush is made in one piece, the entire brush that needs to be repaired must be replaced in order to repair the damaged part, and thus there is a problem in that the replacement work is not easy.

On the other hand, in recent years, an automatic car wash system for washing a vehicle while the driver of the vehicle is in a vehicle has been widely used. In such automatic car wash systems, the brush generates noise (i.e., the noise that strikes the vehicle as the brush rotates) while the vehicle is being cleaned, which causes the vehicle driver and passengers to have psychological anxiety. In addition, the automatic car wash system cleans the vehicle by rotating the brush. Since the brush is composed of several strands of fibers, the surface contacting the surface of the vehicle is not uniform, and thus the car wash is performed directly by the vehicle driver or manager. In addition to low vehicle cleaning power, there is a problem in that an additional device for applying wax sprayed to polish the vehicle is required.

Accordingly, the present invention is to solve the above-described problems, by using a roll-type cloth brush composed of a plurality of cloth units, to provide the vehicle cleaning power as in the car wash performed directly by the vehicle driver or manager and In addition, the object of the present invention is to provide an automatic car wash system that reduces noise generated during the washing process, prevents damage to the vehicle, and performs gloss treatment of the vehicle without additional equipment.

As shown in FIG. 1, the automatic car wash system 1 according to the present invention is a top brush for cleaning the upper surface of the vehicle 6, that is, the front and rear windows and the outer surface of the upper portion of the vehicle. brush (2), left and right windows of the vehicle (6), side mirrors (side mirrors), side brushes (3a, 3b) for cleaning the outer side, all car washing operations of the automatic car wash system (1) PLC (Programmable Logic Controller) 4 for controlling the control, and a sensing sensor (not shown) for detecting the entry and position of the vehicle (6). Here, the top brush 2 and the side brushes 3a and 3b are made of a cloth such as, for example, a non-woven fabric. In addition, the automatic car wash system 1 may further include a rocker brush (not shown) used with the side brushes 3a and 3b to clean the outer side of the curved vehicle 6. .

When the vehicle 6 enters a predetermined position in the automatic car wash system 1, the sensing sensor senses the front part of the vehicle 6 to provide a vehicle entry signal indicating that the vehicle 6 has entered the predetermined position. Transfer to (4). In addition, the detection sensor detects the position of the vehicle 6 in the automatic car wash system 1 and transmits the vehicle position signal to the PLC 4.

In response to the vehicle entry signal and the vehicle position signal transmitted from the sensing sensor, the PLC 4 reads information about the vehicle 6 previously databased from the memory (not shown) to clean the vehicle 6. To control a series of actions. The information about the vehicle may include data necessary for the washing process, such as height, width, and length of the vehicle to be cleaned, that is, data used to control the rotational speed and position of the top brush 2 and the side brushes 3a and 3b. It is included. In detail, the PLC 4 controls the raising and lowering operation of the top brush 2 for cleaning the upper surface of the vehicle 6 based on the information read from the memory, and the washing module of the top brush 2 ( A driving signal for rotating the washing module 10 (see Fig. 2 (a)) at a predetermined speed is applied to the rotary motor 5a of the top brush 2. Similarly, in order to clean the left and right windows, the side mirrors, and the outer side of the vehicle 6, the PLC 4 uses the rotation motors 5b and 5c of the side brushes 3a and 3b based on information read from the memory. By applying a drive signal to the side, the cleaning modules of the side brushes 3a and 3b are rotated at a predetermined speed.

Referring to Figure 2 (a), it is a front view of a cloth brush according to an embodiment of the present invention. As shown in Figure 2 (a), the cloth brush according to an embodiment of the present invention is a cleaning module 10 and a rotating shaft 12 composed of a plurality of cloth units (20) (see Fig. 2 (b)). ). The cleaning module 10 is mechanically connected to a hole provided on the outer circumferential surface of the rotating shaft 12 through a fixing member such as a bolt. For example, in the case of the top brush 2, one end of the rotary shaft 12 is mechanically connected to the rotary shaft of the rotary motor 5a, and the other end of the rotary shaft 12 is the main frame of the automatic car wash system 1. It is connected to a bearing housing (not shown) provided on the main frame 7. In contrast, in the case of the side brushes 3a and 3b, only one end of the rotary shaft 12 is mechanically connected to the rotary shafts of the rotary motors 5b and 5c. Rotating shaft 12 is made of a material such as PVC pipe and aluminum pipe to reduce the weight of the cloth brush itself, but the present invention is not limited to this, any material that can support the cleaning module 10 may be good.

Each cloth unit 20 constituting the cleaning module 10 is composed of, for example, four cloth 30, as shown in Figure 2 (b), each cloth 30 through a sewing operation Are connected to each other. A plurality of such cloth units 20 are continuously connected to the outer circumferential surface of the rotating shaft 12 through fixing members such as bolts, thereby forming the washing module 10 shown in FIG. For example, the cleaning module of the top brush 2 according to the embodiment of the present invention is composed of 42 cloth units 20, and the cleaning modules of the side brushes 3a and 3b are 36 cloth units 20. It is configured, the washing module of the rocker brush is composed of 12 cloth units (20). According to the present invention, when damage occurs to the washing module 10 when washing the vehicle, it is very easy to maintain and repair since only the corresponding cloth unit 20 that is damaged can be replaced without having to replace the whole washing module 10. .

Each fabric 30 constituting the fabric unit 20 according to the present invention, as shown in Fig. 2 (c), contains water as an embossed polypropylene nonwoven fabric fabric 30 Because of excellent flexibility and good flexibility, it is in contact with the surface of the vehicle gently to prevent damage to the surface of the vehicle during the cleaning process, as well as to reduce noise and is characterized by excellent durability. As shown in FIG. 2 (c), the fabric 30 bent into a fan shape is manufactured as the cloth unit 20 through a sewing operation, and a through hole into which a fixing member for connecting to the rotating shaft 12 is inserted. It comprises a connecting portion 40 including).

Hereinafter, with reference to Figure 3 will be described for the cloth brush rotation control in the vehicle washing process according to the present invention.

The PLC 4 applies the drive signal to the rotary motor 5a when the vehicle 6 enters the preset position of the automatic car wash system 1 to rotate the top brush 2 and at the same time the main frame 7. Detergent and car wash water are sprayed to the vehicle through an injection nozzle (not shown) provided on the upper surface. Next, a controller (not shown) attached to the rotary motor 5a detects a load amount applied to the rotary motor 5a due to the contact of the vehicle with the washing module 10 of the top brush and then the washing module. The signal for changing the position of 10 is transmitted to the PLC 4. In response to the position change signal, the PLC 4 not only changes the position of the washing module 10 relative to the vehicle 6 by raising and lowering the top brush, but also rotates the washing module 10 in the rotary motor 5a. The rotation direction control signal for controlling the direction is applied.

As shown in FIG. 3, the PLC 4 raises the top brush in the sections A to B of the vehicle 6 and simultaneously moves the washing module 10 in the direction opposite to the traveling direction of the vehicle 6. The vehicle 6 is cleaned while rotating (hereinafter referred to as "forward rotation"). At this time, as the top brush moves from the section A to the section B, the load added to the rotating motor 5a increases due to the contact between the washing module 10 and the vehicle. The controller attached to the rotary motor 5a compares the load detected during the washing module 10 with the vehicle 6 and the corresponding data which is databased in the memory of the automatic car wash system 1 to change the position change signal. To the PLC 4. In response to the position change signal, the PLC 4 changes the position of the cleaning module 10 relative to the vehicle 6 by raising and lowering the top brush. In the section B, since the vehicle 6 is cleaned by the forward rotation of the cleaning module 10, there is no risk that the front window wiper of the vehicle 6 is damaged by the rotation of the cleaning module 10. In addition, in order to prevent damage to the front window wiper, the rotational speed of the cleaning module 10 in the section B is controlled by the PLC 4 to rotate at a lower speed than the sections A and C. In the section C, the position of the washing module 10 with respect to the vehicle 6 is kept constant, and the vehicle washing is continuously performed by the forward rotation of the washing module 10.

However, if the rear window wiper of the vehicle 6 is present, there is a risk that the rear window wiper is damaged by the rotation of the cleaning module 10 if the cleaning module 10 continues to rotate forward. Therefore, in the section D to the section E where the top brush descends, the PLC 4 washes the vehicle 6 while rotating the washing module 10 in reverse (that is, rotating in the same direction as the traveling direction of the vehicle). In addition, in order to prevent damage to the rear window wiper, the rotation speed of the cleaning module 10 in the section D in which the rear window wiper is present is controlled by the PLC 4 to rotate at a lower speed than the sections C and E.

When the washing of the vehicle 6 using the detergent and the wash water is completed, the PLC 4 sprays the wax on the vehicle through the spray nozzle and applies the wax to the vehicle 6 through the cleaning process of the cloth brush described above. . The vehicle 6 polished by the rotation of the cloth brush is dried by a blower (not shown) of the automatic car wash system 1, thereby completing all vehicle car washing operations of the automatic car wash system 1.

In the present specification, only the rotation control of the top brush 2 is described, but those skilled in the art can easily implement the rotation control of the side brushes 3a and 3b and the rocker brush similarly to the rotation control of the top brush 2 described above. You will know.

As described above, according to the present invention, by using a roll-type cloth brush composed of a plurality of cloth units, it provides the vehicle cleaning power as in the car wash performed directly by the vehicle driver or manager, and during the cleaning process It reduces noise and prevents damage to the surface of the vehicle, as well as the ability to carry out the gloss of the vehicle without additional equipment. In addition, by controlling the rotation direction of the cloth brush relative to the vehicle when the vehicle is washed, there is a feature that can prevent damage to the wiper and the like attached to the vehicle.
