TECHNICAL FIELD
The present disclosure generally relates to a vehicle wash component for use in cleaning an exterior surface of a vehicle. More particularly, the present disclosure relates to a vehicle wash component that provides for improved contact with and cleaning of a vehicle exterior during a vehicle wash process.
BACKGROUND OF THE INVENTION
A fundamental objective of a vehicle wash system is to provide a process that thoroughly washes and cleans the exterior surface of a vehicle. The ability to achieve this objective depends, in large part, on the configuration and function of the vehicle wash components that treat the vehicle exterior. Many different types of vehicle wash components exist for washing and removing dirt from a vehicle exterior. One such current vehicle wash component is configured as a rotary brush with a plurality of media elements secured to a rotating hub. As a vehicle is conveyed through the vehicle wash facility, the rotary brush rotates and the media elements contact the exterior of the vehicle to remove dirt from and clean the vehicle exterior. Multiple rotary brushes are generally disposed adjacent a vehicle treatment area in the vehicle wash facility and contact the top surface (top brush) and side surfaces (side brushes) of a vehicle to clean the entire exterior surface.
While these rotary brushes work satisfactorily, they have known limitations. For example, most current rotary side brushes are oriented such that their axis of rotation is generally perpendicular to the ground. By this configuration, the media elements each extend the same distance into the vehicle treatment area. This provides sufficient cleaning for a vehicle having a side surface that is also generally perpendicular to the ground. However, current rotary brushes have cleaning limitations for vehicles with large angled side surfaces. This is because contact between the media elements of the rotary side brush and the large angled side surface of the vehicle is decreased due to the fact that the media elements do not extend into the vehicle treatment area a sufficient distance to contact the entirety of the angled side surface. As such, the quality of the cleaning is significantly reduced.
In an attempt to overcome this limitation, vehicle wash components have been introduced where the axis of rotation of the rotary brush can be moved from a vertical position to a fixed angled position in an effort to correspond to an angled exterior surface of the vehicle. By this configuration, the upper media elements of the brushes extend further into the vehicle treatment area and can thus better engage an angled upper surface of a vehicle. On the other hand, the media elements on the lower portions of the brush are disposed further away from the vehicle treatment area. Thus, while these tilted rotary brushes provide improved cleaning on the upper angled surfaces of the vehicle exterior, the quality of cleaning on the lower vertical surfaces of the vehicle is known to suffer. In other words, while the upper media elements engage the angled surface of the vehicle exterior, the lower media elements often do not sufficiently engage the lower vertical surfaces to provide the desired cleaning.
Another issue with current vehicle wash components is their inability to provide consistent cleaning for all vehicle widths. For example, while current vehicle wash components provide acceptable cleaning for some vehicle sizes and widths, they often are unable to provide the same cleaning of other vehicle sizes.
SUMMARY OF THE INVENTION
It is therefore an aspect of the present disclosure to provide a vehicle wash component that provides consistent cleaning for vehicles of different widths and sizes.
It is another aspect of the present disclosure to provide a vehicle wash component that provides improved cleaning for vehicles having exteriors with different contours and shapes.
It is still another aspect of the present disclosure to provide a vehicle wash component that is configurable to match the exterior surface of the vehicle to be cleaned.
It is yet a further aspect of the present disclosure to provide a vehicle wash system that operates under computer control to provide synchronized lighted vehicle wash components.
It is a further aspect of the present disclosure to provide a vehicle wash component that generates less noise during operation than existing vehicle wash components.
It is yet another aspect of the present disclosure to provide a vehicle wash component that yields significant energy savings for a vehicle wash operator.
It is still yet another aspect of the disclosure to provide a vehicle wash component that provides a more enjoyable vehicle wash experience for customers.
It is still a further aspect of the present disclosure to provide a vehicle wash component where the position of the vehicle wash component is determined by the geometry of the vehicle.
In accordance with the above and the other aspects of the present disclosure, an improved vehicle wash component is provided. The vehicle wash component includes a first brush portion and a second brush portion. The first brush portion includes a first distal end and a first proximate end opposite the first distal end. The first brush portion also includes a first rotary hub which defines a first axis of rotation. The second brush portion is in communication with the first brush portion and includes a second distal end and a second proximate end opposite the second distal end. The second brush portion also includes a second rotary hub, which defines a second axis of rotation. The first rotary hub is rotatably coupled to the second rotary hub. An actuator is in communication with the first hub to effectuate movement of the first distal end between an extended position and a retracted position. In the retracted position, the first axis of rotation and the second axis of rotation are generally parallel. In the extended position, the first axis of rotation is at an angle with respect to the second axis of rotation.
In accordance with another aspect of the disclosure, a vehicle wash component includes an upper brush portion and a lower brush portion. The lower brush portion includes a lower rotary hub defining a lower axis of rotation. The lower hub portion has a plurality of media elements secured thereto. The upper brush portion includes an upper rotary hub defining an upper axis of rotation. The upper rotary hub has a plurality of media elements secured thereto. The upper rotary hub and the lower rotary hub are rotatably coupled for rotation in unison. The component is configured such that the lower axis of rotation and the upper axis of rotation may be different.

This may allow the top brush portion 116 to be tilted with respect to the bottom brush portion 114 such that an angle between them can be varied. According to another aspect, the connector 160 may be an angular misalignment coupling or flexible coupling, however, a variety of other suitable connectors may be utilized, including a u-joint. According to a further aspect, the top brush portion 116 may rotate independently of the bottom brush portion 114.
Additionally, as shown, a connector bar 162 may extend between the upper manifold portion 150 and the top brush portion 116 to provide support thereto. The connector bar 162 may have an inner end 164 that is in pivotal communication with the connector 160 and an outer end 166 that is connected to the upper manifold portion 150. According to an aspect, the connector bar 162 may be in communication with an actuator 168 to effectuate movement thereof, as discussed below. The actuator 168 may be a plurality of pneumatic cylinders. However, a variety of other cylinders or actuator mechanism may be employed. According to a still further aspect, the actuator 168 may be in communication with the controller 38 to effectuate automatic movement of the top brush portion 116 as needed during the vehicle wash process. As shown, the actuator 168 has an upper end 170 secured to the connector bar 162 and a lower end 172 secured to the upper support arm 156. As also shown, a spring 174 has an upper end 176 secured to the connector bar 162 and a lower end 178 secured to the upper support arm 156.
The actuator 168 may effectuate pivotal movement of the connector bar 162 such that the top brush portion 116 may be moved from a retracted position to a deployed position. In the retracted position, the top brush portion 116 is biased inwardly by the actuator 168 as best shown in FIGS. 7, 8 and 13, in the retracted position the axis of rotation AB may be generally parallel with the axis of rotation AT and both axes may be oriented generally vertically within the facility and with respect to one another. As used herein, the term “vertically” encompasses a configuration where generally the axis of rotation AB may be at a slight angle with respect to the axis of rotation AT, such as 5 degrees, so that it is biased for contacting a vehicle with sufficient pressure to promote effective cleaning. It will be appreciated that the starting angle between the axis of rotation AB and AT in the retracted position may vary. For example, it could be 0 degrees such that they are both entirely in line and could be greater than 5 degrees.
In the deployed position, the outer end 166 of the connector bar 162 may be raised by the lifting of the upper end 170 of the actuator such that the connector bar 162 pivots about its inner end 164. As the actuator 168 pivots, the upper end 176 of the spring 174 is pulled upwardly against the spring force bias. To move to the deployed position, the actuator 168 may lower the connector bar 162 with assistance from the force of spring 174. This can cause the upper end 170 of the top brush portion 116 to pivot inwardly toward the vehicle treatment area 36 with respect to a lower end 172 of the top brush portion 116. By this orientation, the upper media elements 142 extend further into the vehicle treatment area 36 and thus can provide increased contact with an angled surface of a vehicle 12. As shown, in the deployed position, the axis of rotation AT may be disposed at angle α with respect to the axis of rotation AB. Again, the top brush portion 116 may be biased inwardly to apply force to a vehicle for effective cleaning. According to an aspect, the actuator 168 may be configured to allow the angle to vary as dictated by the exterior surface of the vehicle.
According to an aspect, the angle α in the deployed position may be between 5 degrees and 25 degrees. According to another aspect, the angle α at which the axis of rotation AT is disposed with respect to the axis of rotation AB may vary. For example, the initial starting angle may vary. Also, the operating angle as dictated by the vehicle exterior may also vary. It will be appreciated that a variety of suitable ways to move the top brush portion 116 from the retracted position to the deployed position may be utilized.
According to one example, when the top brush portion 116 is moved to the deployed position, the controller 38 may direct the actuator 168 to move the top brush portion 116 to a fixed predetermined angle α, i.e., 20 degrees. According to another aspect, the controller 38 may be in communication with a variety of sensors utilized in the vehicle wash system 10 to gather information about the vehicle, including its width and any contours. This vehicle information may be fed to the controller 38 and then utilized to determine the angle α at which to orient the axis of rotation AT with respect to the axis of rotation AB. For example, the controller 38 may receive information about the configuration and angle of the upper exterior surface of the vehicle 12 from one or more sensors. Based on this information, the controller 38 could determine the angle α at which to adjust the top brush portion 116 in order to provide efficient cleaning of all vehicle surfaces. Moreover, the exterior of a vehicle could contact the top brush portion 116 during operation and move it outwardly against the force of the actuator 168 to vary the angle and accommodate the configuration of the vehicle exterior as assisted by the spring 174. By this configuration, the angle that the top brush portion extends inwardly can consistently vary to provide efficient cleaning.
It will be appreciated that while according to one aspect, the top brush portion 116 may be configured to pivot with respect to the bottom brush portion 114 such that the top brush portion 116 is angled inwardly with respect to the bottom brush portion 114, according to another aspect, the top brush portion 116 could be configured to pivot outwardly (away from the vehicle treatment area 36) with respect to the bottom brush portion 114. According to a still further aspect, the bottom brush portion 114 could be configured to pivot either inwardly toward or outwardly away from the vehicle treatment area 26 with respect to the top brush portion 116. Still further, both the top brush portion 116 and the bottom brush portion 114 could be configured to pivot at the same time such they each create angles with respect to a vertical axis of rotation.
