Description

  The present invention relates to a car wash machine for applying a coating agent to a vehicle to be cleaned.

  A conventional car wash machine installed in a gas station or the like is disclosed in Patent Document 1. The car wash machine includes a car wash machine body that moves in the front-rear direction with respect to the vehicle to be washed. The car wash machine main body has two left and right opposing stand parts and a ceiling part that connects the upper ends of the stand parts, and is formed in a gate shape straddling the vehicle to be cleaned.

  The car wash machine body is provided with a rotating brush, a cleaning nozzle, and a coat nozzle. The rotating brush slides on the vehicle to be cleaned and cleans the vehicle to be cleaned. The cleaning nozzle sprays cleaning water such as city water or detergent water onto the surface of the vehicle to be cleaned when the rotary brush is cleaned. The coating nozzle sprays an aqueous solution of a coating agent having water repellency onto the surface of the vehicle to be cleaned.

  In the car wash machine configured as described above, when the car wash is started, wash water is jetted by the wash nozzle and the surface of the vehicle to be washed is washed by the rotating brush. When the cleaning of the vehicle to be cleaned is finished, an aqueous solution of the coating agent is sprayed from the coat nozzle. Thereby, the film by application | coating of a coating agent is formed in the surface of a to-be-cleaned vehicle, and the water repellency of a window glass and a vehicle body (painted surface) is obtained.

JP2013-95234A (FIG. 3 etc.)

  However, according to the conventional car wash machine described above, the adsorptivity of the coating agent decreases depending on environmental conditions such as when the water temperature or the outside temperature of the water in which the coating agent is mixed is low or when the water quality changes. In addition, the adsorptivity of the coating agent decreases due to vehicle conditions such as scratches on the body surface, adhesion of iron powder, and deterioration of the clear layer. For this reason, there is a problem that a sufficient film cannot be formed on the surface of the vehicle to be cleaned, and the water-repellent performance, antifouling performance, or coating performance such as durability thereof is lowered.

  An object of this invention is to provide the car wash machine which can improve coating performance.

  In order to achieve the above object, the present invention provides a car wash machine body that moves relative to the vehicle to be cleaned in the front-rear direction, a rotary brush that is disposed in the car wash machine body and cleans the car to be cleaned, and the rotary brush. A cleaning nozzle for injecting cleaning water onto the vehicle to be cleaned at the time of cleaning with the first coating nozzle, and a first coating nozzle and a second coating nozzle for spraying a coating agent on the vehicle to be cleaned after cleaning with the rotating brush, The injection area on the vehicle to be cleaned and the injection area on the vehicle to be cleaned of the second coat nozzle are arranged apart from each other in the front-rear direction.

  According to the present invention, in the car wash machine having the above-described configuration, the first coat nozzle is disposed in front of the second wash nozzle in the traveling direction of the car wash machine body when the coating agent is applied. The pressure is larger than the spray pressure of the second coat nozzle.

  In the car wash machine having the above-described configuration, the present invention is characterized in that an injection angle of the first coat nozzle is smaller than an injection angle of the second coat nozzle.

  According to the present invention, in the car wash machine configured as described above, the rotating brush is disposed between the first coat nozzle and the second coat nozzle.

  Further, the present invention is characterized in that, in the car wash machine having the above-described configuration, the coating agent has water repellency.

  Moreover, the present invention is characterized in that, in the car wash machine having the above-described configuration, a base layer having a higher adsorptivity than the coating agent is provided below the coating agent.

  Further, the present invention is characterized in that, in the car wash machine configured as described above, the first coat nozzle and the second coat nozzle for injecting the coating agent onto the upper surface of the vehicle to be cleaned swing in the left-right direction.

  According to the present invention, the injection region of the first coat nozzle on the vehicle to be cleaned and the injection region of the second coat nozzle on the vehicle to be cleaned are arranged apart from each other in the front-rear direction. As a result, the coating agent sprayed from the first coating nozzle is applied to the surface of the vehicle to be cleaned while removing the water film formed on the vehicle to be cleaned during cleaning. Further, a coating agent sprayed from the second coating nozzle after a predetermined time has elapsed is applied to the surface of the vehicle to be cleaned. For this reason, even when environmental conditions and vehicle conditions are bad, the coating film of the coating agent can be uniformly and sufficiently formed on the vehicle to be cleaned. Therefore, the coating performance by the coating agent can be improved.

The water purification nozzle 12 is disposed between the shampoo nozzle 11 and the inlet surface 1a, and the water purification nozzle 13 is disposed between the top brush 4 and the outlet surface 1b. The water purification nozzle 14 is provided on the housing of the top blowing nozzle 21.

  The water purification nozzles 12, 13, and 14 inject cleaning water made of city water onto the vehicle CA to be cleaned. The water-cleaning nozzles 12, 13, and 14 perform washing of the vehicle CA to be washed by washing with water and rinsing with a detergent or a coating agent to be described later. Thereby, the water purification nozzles 12, 13, and 14 function as cleaning nozzles for cleaning the vehicle CA to be cleaned.

  The wax nozzle 15 is provided on the ceiling portion 91 and is provided on both stand portions 90 although not shown. The wax nozzle 15 is disposed between the water purification nozzle 13 and the outlet surface 1b, and sprays an aqueous solution of wax that is a coating agent for polishing.

  The coat nozzles 40, 41, and 42 (first coat nozzles) spray an aqueous solution of a water-repellent coating agent (hereinafter referred to as “first coating agent”) that imparts water repellency to the vehicle CA to be cleaned. A plurality of coat nozzles 40 (two in this embodiment) are provided on the ceiling portion 91 and are formed so as to be swingable in the left-right direction. The coat nozzle 40 sprays the first coating agent toward the upper surface of the vehicle CA to be cleaned. The coat nozzles 41 and 42 are arranged on the stand unit 90 and spray the first coating agent toward the side surface of the vehicle CA to be cleaned. The upper coat nozzle 41 is formed to be swingable in the vertical direction.

  The coat nozzles 46, 47 and 48 (second coat nozzles) inject an aqueous solution of the first coating agent onto the vehicle CA to be cleaned. Similarly to the above, a plurality (two in this embodiment) of the coating nozzles 46 are provided on the ceiling portion 91 and are formed so as to be swingable in the left-right direction. The coat nozzle 46 injects the first coating agent toward the upper surface of the vehicle CA to be cleaned. The coat nozzles 47 and 48 are disposed on the stand unit 90 and spray the first coating agent toward the side surface of the vehicle CA to be cleaned. The upper coat nozzle 47 is formed to be swingable in the vertical direction.

  The coat nozzle 40 and the coat nozzle 46 branch in the front-rear direction with the top brush 4 interposed therebetween, and are spaced apart by a predetermined distance d2 (for example, 1400 mm) in the front-rear direction. Thereby, the injection area | region on the to-be-cleaned vehicle CA of the coat nozzle 40 and the injection area | region on the to-be-cleaned vehicle CA of the coat nozzle 46 do not overlap, but are arrange | positioned away in the front-back direction. In addition, a pair of left and right coat nozzles 40 and 46 are provided, and are arranged separated by a predetermined distance d1 (for example, 870 mm) in the left-right direction.

  Similarly, the coat nozzle 41 and the coat nozzle 47 branch in the front-rear direction with the top brush 4 interposed therebetween, and are disposed apart by a predetermined distance in the front-rear direction so that the injection regions do not overlap. The coat nozzle 42 and the coat nozzle 48 branch in the front-rear direction with the top brush 4 interposed therebetween, and are disposed at a predetermined distance in the front-rear direction so that the spray areas do not overlap.

  The spray angle θ1 (see FIG. 5) of the coat nozzles 40, 41, 42 arranged on the inlet surface 1a side is set to 14 °, for example. The spray angle θ2 (see FIG. 5) of the coat nozzles 46, 47, and 48 arranged on the exit surface 1b side is larger than the spray angle θ1, and is set to 40 °, for example. When the injection angle is large, the injection pressure is reduced due to pressure loss, so that the injection pressure (eg, 2 MPa to 3 MPa) of the coat nozzles 40, 41, and 42 is larger than the injection pressure of the coat nozzles 46, 47, and 48.

  The coat nozzles 43 and 44 spray an aqueous solution of a coating agent different from the first coating agent (hereinafter referred to as “second coating agent”). A plurality of coat nozzles 43 (two in this embodiment) are provided on the ceiling portion 91, and spray the second coating agent toward the upper surface of the vehicle CA to be cleaned. The coat nozzle 44 is disposed on the stand unit 90 and sprays the second coating agent toward the side surface of the vehicle CA to be cleaned.

  The first coating agent sprayed from the coat nozzles 40, 41, 42 and the coat nozzles 46, 47, 48 has silicone oil as a main component. The film of the first coating agent has water repellency with a large contact angle due to surface tension, and imparts water repellency to the surface of the vehicle CA to be cleaned.

  The second coating agent sprayed from the coating nozzles 43 and 44 is mainly composed of silicone oil having a higher adsorptivity to the vehicle CA to be cleaned than the first coating agent. The second coating agent has a high adsorptivity with respect to the first coating agent. For this reason, when a 1st coating agent is apply | coated on a 2nd coating agent, a 2nd coating agent forms the base layer which improves the adsorptivity of a 1st coating agent.

  The wax nozzle 15 and the coating nozzles 40 to 44 and 46 to 48 can eject city water by stopping the supply of the liquid agent, and can function as cleaning nozzles.

  In the car wash machine WA having the above-described configuration, the user drives to stop the vehicle to be cleaned CA in front of the remote panel 7, and sets the car wash conditions for the vehicle to be cleaned CA from within the vehicle to be cleaned CA. After setting the car wash conditions, the user moves the to-be-washed vehicle CA to a predetermined washing start position.

  By operating the remote panel 7, a water washing course, a shampoo course, a wax course, and a water repellent course can be selected. In the water washing course, the washing brush CA is washed by spraying city water washing water from the water purification nozzles 12, 13, 14 and the like by rotating a rotating brush. The shampoo course rotates the rotating brush to inject cleaning water containing detergent from the shampoo nozzle 11 to clean the vehicle CA to be cleaned. At this time, the cleaning water is rinsed by jetting city water washing water from the water purification nozzles 12, 13, 14 and the like.

  As in the shampoo course, the wax course is applied to the vehicle body by the wax nozzle 15 after washing the vehicle CA to be washed. In the water repellent course, the washed vehicle CA is washed in the same manner as the shampoo course, and then the water repellent first coating agent is applied to the washed vehicle CA.

  3 to 8 are side views showing the car wash state of the water repellent course. When the water-repellent course is selected and the car wash is started, as shown in FIG. 3, a first forward process is performed in which the car wash machine main body 1 moves to the rear (arrow E1) of the vehicle CA to be cleaned. In the first outward path process, while the shape sensor 9 detects the shape of the vehicle CA to be cleaned, each rotary brush rotates to clean the front and rear surfaces and the upper surface of the vehicle CA to be cleaned. At this time, cleaning water S1 containing a detergent is sprayed from the shampoo nozzle 11 preceding the rotating brush, and city water cleaning water S2 is sprayed from the water purification nozzle 13 following the top brush 4.

  When the cleaning of the rear surface of the vehicle CA to be cleaned is completed, a first return path process is performed in which the car washer main body 1 is inverted and moved to the front (arrow E2) of the vehicle CA to be cleaned as shown in FIG. In the first return path process, the rotating brush is stopped, the second coating agent S4 is sprayed from the coat nozzles 43 and 44, and the city water wash water S2 is sprayed from the water purification nozzle 12 and the wax nozzle 15.

  The detergent is rinsed with the washing water S2 sprayed from the wax nozzle 15 preceding the coat nozzles 43 and 44. The second coating agent S4 sprayed from the coating nozzles 43 and 44 forms a base layer of the first coating agent on the vehicle CA to be cleaned. Excess second coating agent S4 is removed by washing water S2 sprayed from water purification nozzle 12 following coating nozzles 43, 44. Thereby, the application | coating nonuniformity of 2nd coating agent S4 can be prevented.

  When the second coating agent S4 is applied to the front surface of the vehicle to be cleaned CA, a second forward process in which the car wash machine body 1 is reversed and moved to the rear (arrow E1) of the vehicle to be cleaned CA as shown in FIG. Done. In the second forward process, the first coating agent S3 is sprayed from the coat nozzles 40 to 42 and the coat nozzles 46 to 48, and the city water wash water S2 is sprayed from the wax nozzle 15.

  At this time, the coat nozzles 40 to 42 are arranged ahead of the coat nozzles 46 to 48 in the traveling direction of the car wash machine body 1. The first coating agent S3 sprayed from the coating nozzles 40 to 42 is applied to the surface of the vehicle to be cleaned CA while removing the water film formed on the vehicle to be cleaned CA in the first return path process. Further, after a predetermined time has elapsed, the first coating agent S3 sprayed from the coating nozzles 46 to 48 is applied to the surface of the vehicle CA to be cleaned. As a result, it is possible to sufficiently form a film composed of the second coating agent S4 and the first coating agent S3 on the vehicle CA to be cleaned.

  Further, since the spray pressure of the coat nozzles 40 to 42 is larger than the spray pressure of the coat nozzles 46 to 48, the first coating agent S3 can be applied by reliably removing the water film on the vehicle CA to be cleaned. In addition, the spray angle θ1 of the coat nozzles 40 to 42 can be made smaller than the spray angle θ2 of the coat nozzles 46 to 48, and the spray pressure of the coat nozzles 40 to 42 can be easily increased.

  Excess first coating agent S3 is removed by washing water S2 sprayed from wax nozzle 15 following coating nozzles 46-48. Thereby, the application | coating nonuniformity of 1st coating agent S3 can be prevented.

  In addition, you may stop injection | pouring of 2nd coating agent S4 by the coating nozzles 43 and 44 at a 1st return path | pass process. At this time, the first coating agent S3 is directly applied to the surface of the to-be-cleaned vehicle CA without the base layer in the second outward path process. In this case as well, as described above, the first coating agent S3 sprayed from the coating nozzles 40 to 42 is applied while removing the water film, and after the predetermined time has elapsed, the first coating agent S3 is applied by the coating nozzles 46 to 48. The For this reason, the film of 1st coating agent S3 can be formed reliably.

  When the second forward path process is completed, as shown in FIG. 6, a second backward path process is performed in which the car wash machine body 1 is reversed and moves in front of the vehicle to be cleaned CA (arrow E <b> 2). In the second return path process, the first coating agent S3 is sprayed from the coat nozzles 40 to 42 and the coat nozzles 46 to 48, and the cleaning water S2 is sprayed from the water purification nozzle 12.

  As a result, the first coating agent S3 is applied by the coating nozzles 46 to 48 on the film of the first coating agent after a predetermined time has elapsed since the application of the first coating agent S3 in the second forward path step. Further, after the first coating agent S3 is applied by the coating nozzles 46 to 48 and a predetermined time has elapsed, the first coating agent S3 is applied by the coating nozzles 40 to 42. Excess first coating agent S3 is removed by washing water S2 sprayed from water purification nozzle 12.

  For this reason, the film thickness of the first coating agent S3 on the vehicle to be cleaned CA can be increased. In addition, when the film thickness of the coating film of the first coating agent S3 can be increased in the second forward step, the second return step may be omitted.

  Further, the traveling speed (for example, 5 m / min) of the second forward path process of the car wash machine body 1 may be set lower than the traveling speed (for example, 10 m / min) of the second backward path process. As a result, the water film can be more reliably removed in the second forward path step, and the film thickness of the first coating agent S3 can be increased.

  When the second return path process is completed, as shown in FIG. 7, a third forward path process is performed in which the car wash machine body 1 is reversed and moved to the rear of the vehicle to be cleaned CA (arrow E1). In the third forward step, the cleaning water S2 is jetted from the water purification nozzle 14. Since the water purification nozzle 14 moves up and down together with the top blowing nozzle 21, it approaches and follows the upper surface of the vehicle CA to be cleaned. Thereby, excess 1st coating agent S3 on the to-be-cleaned vehicle CA can be removed more reliably. If the excess coating agent S3 can be removed in the second forward step, the third forward step may be omitted.

  When the cleaning by the water purification nozzle 14 is completed, as shown in FIG. 8, a third return path process is performed in which the car washer main body 1 is inverted and moved to the rear (arrow E1) of the vehicle to be cleaned CA. In the third return path step, the air flow A1 is sent out from the top blowing nozzle 21 and the side blowing nozzle 22, and the vehicle CA to be cleaned is dried. This completes the car wash.

  According to the present embodiment, the spray region on the to-be-cleaned vehicle CA of the coat nozzles 40 to 42 (first coat nozzle) and the spray region on the to-be-cleaned vehicle CA of the coat nozzles 46 to 48 (second coat nozzle) are front and back. Arranged away in the direction. As a result, the first coating agent S3 sprayed from the coating nozzles 40 to 42 preceding in the second forward step is removed from the surface of the vehicle CA to be cleaned while removing the water film formed on the vehicle CA to be cleaned at the time of cleaning. Applied. Furthermore, the first coating agent S3 sprayed from the subsequent coating nozzles 46 to 48 after a predetermined time has elapsed is applied to the surface of the vehicle CA to be cleaned.

  For this reason, even if environmental conditions and a vehicle state are bad, the film of 1st coating agent S3 can be uniformly and fully formed on the to-be-cleaned vehicle CA. Therefore, the coating performance with the first coating agent S3 can be improved.

  Further, the spray pressure of the preceding coat nozzles 40 to 42 in the second forward process of applying the first coating agent S3 is larger than the spray pressure of the subsequent coat nozzles 46 to 48. Thereby, a water film can be reliably removed by the first coating agent S3 sprayed from the coating nozzles 40 to 42 to form a film, and the coating performance of the car wash machine WA can be further improved.

  Further, since the spray angle θ1 of the coat nozzles 40 to 42 is smaller than the spray angle θ2 of the coat nozzles 46 to 48, the spray pressure of the coat nozzles 40 to 42 can be easily increased.

  Further, since the top brush 4 is disposed between the coating nozzles 40 to 42 and the coating nozzles 46 to 48, the distance in the front-rear direction between the coating nozzles 40 to 42 and the coating nozzles 46 to 48 can be increased. Thereby, the injection area | region on the to-be-cleaned vehicle CA of the coating nozzles 40-42 and the injection area | region on the to-be-cleaned vehicle CA of the coating nozzles 46-48 can be arrange | positioned reliably away in the front-back direction.

  In addition, after rinsing and washing in the first return pass process, the car wash machine body 1 is reversed and the first coating agent S3 is applied by the coat nozzles 40 to 42 and the coat nozzles 46 to 48 in the second forward pass process. Accordingly, the cleaning water S2 sprayed onto the vehicle to be cleaned CA in the first return path process sufficiently flows down before the first coating agent S3 is sprayed, and the film thickness of the water film on the vehicle to be cleaned CA can be reduced. it can. Therefore, the film of the first coating agent S3 can be more reliably formed on the vehicle CA to be cleaned.

  In addition, since the first coating agent S3 has water repellency, the rain that has fallen on the vehicle CA to be cleaned flows down and the adhesion of dirt can be suppressed.

  In addition, since the base layer is formed in the lower layer of the first coating agent S3 by the second coating agent S4 having higher adsorbability than the first coating agent S3, the adsorptivity of the first coating agent S3 can be improved. Therefore, the film of the first coating agent S3 can be more reliably formed on the vehicle CA to be cleaned.

  In addition, since the coat nozzle 40 and the coat nozzle 46 swing in the left-right direction, the quantity of the coat nozzle 40 and the coat nozzle 46 can be reduced, and a decrease in the injection pressure due to the increase in quantity can be prevented.

  In the present embodiment, the wax nozzle 15 may be configured in the same manner as the coat nozzles 40 to 42 and the coat nozzles 46 to 48 to form a wax film which is a coating agent for polishing.

  As described above, according to the present invention, in a car wash machine that applies a coating agent such as a water-repellent coat or wax at the time of car washing, the car wash machine WA that always forms a coating film of the coating agent and exhibits coating performance. Can be provided.

  According to the present invention, it can be used for a car wash machine for applying a coating agent to a vehicle to be cleaned.
