  Embodiments of the present invention will be described below with reference to the drawings. Moreover, the same code | symbol is used about the same structural member, and detailed description is abbreviate | omitted suitably.

  The car wash machine WA of the present embodiment includes a washing means and a drying means, and is a car wash machine for washing a vehicle to be washed while moving the car wash machine body and the vehicle to be washed relative to each other in the front-rear direction. It is set as the structure similar to the car wash machine WB shown in FIG. However, the difference is that it has a lower surface cleaning device for cleaning the lower surface of the vehicle to be cleaned. For this purpose, as shown in FIG. 8, a bottom surface cleaning device WC is disposed between the pair of left and right rails 2 of the gate-type car wash machine body 1 that travels along the rails 2 via the wheels 3. Yes.

  Further, instead of the vehicle height detection sensor 8 described above, or in addition to the vehicle height detection sensor 8, a vehicle shape detection sensor (area sensor) including a transmission type photoelectric sensor may be used. In this case, a projector is provided in the vertical direction on one side of the car wash machine main body 1, and a light receiver is provided in the vertical direction on the other side opposite to these projectors, thereby entering the cleaning position. The vehicle shape of the vehicle to be cleaned is detected, and the front end portion, rear end portion, and bonnet height are detected.

  The lower surface cleaning device WC includes a lower surface cleaning cart 30 that travels on the traveling rail 32. In addition, a plurality (for example, three as shown in FIG. 6) of cleaning water injection nozzles 31 (see FIG. 6) for injecting cleaning water toward the lower surface of the vehicle to be cleaned are provided on the upper surface of the lower surface cleaning carriage 30. ing.

  In addition, as a configuration that moves in conjunction with the car wash machine main body 1, while washing the side surface of the vehicle CA to be cleaned using the side brush 5, while moving the lower surface cleaning device WC along the lower surface of the vehicle CA to be cleaned, Cleaning water can be sprayed from the cleaning water spray nozzle 31 to clean the lower surface of the vehicle to be cleaned.

  The lower surface cleaning apparatus WC, for example, as in the first embodiment shown in FIG. 6, can travel on the traveling rails 32, 32 installed between the pair of left and right rails 2, 2 on which the car wash machine body 1 travels. A traveling carriage 30 is provided.

  The traveling carriage 30 may be a self-propelled traveling carriage provided with a drive source in the carriage body, or may be configured to travel and move with a separately provided drive source, and is not particularly limited. In addition, the cleaning water is supplied from a tank provided outside through a pipe. The piping stably supplies cleaning water to a traveling carriage that reciprocally moves using piping that is disposed so as to be able to bend in a cable bear system, for example.

  The start of the car wash process is started after a user who wishes to wash the car sets a predetermined car wash mode on the remote panel 7A and stops the vehicle to be cleaned CA at a predetermined car wash position between the rails 2 and 2. First, when it is detected that the vehicle to be cleaned CA has reached a predetermined car wash position, the car wash machine main body 1 in the standby position moves forward toward the car to be cleaned CA and executes a predetermined car wash process. Alternatively, after a user wishing to wash the car stops the car to be washed CA at a predetermined car wash position between the rails 2 and 2, a predetermined car wash mode is set on the operation panel 7 installed in the car wash machine body, and the car wash process is started. A configuration may be adopted.

  The car wash machine main body 1 includes an area sensor 9 having a projector 9A and a light receiver 9B as shown in the figure, for example, and the distance traveled when the car wash machine main body 1 travels and the object detected by the area sensor 9 are detected. The vehicle length and the vehicle body shape are recognized from the front end position and the rear end position of the cleaning vehicle CA. Further, the car wash is started from the position where the pair of left and right side brushes 5 and 5 are closed and brought into contact with the tip of the vehicle to be cleaned CA.

  The pair of left and right side brushes 5 and 5 are openable and closable in the vehicle width direction of the vehicle CA to be cleaned, and each brush shaft is rotatably suspended via a swing support portion. Car wash is performed by abutting in an inclined state corresponding to the inclined side surface of the cleaning vehicle CA. Further, the front portion of the vehicle to be cleaned CA is washed by rotating and opening while in contact with the front surface of the vehicle CA to be cleaned. After washing the front part, when it goes around the side surface of the vehicle body, it moves forward together with the car wash machine main body 1 while maintaining the state in contact with the side surface part of the vehicle body to wash the side surface part of the vehicle body. In addition, after the car wash of the side surface is finished, the car wash machine 1 stops traveling, and the pair of left and right side brushes 5 and 5 are gradually closed from the open state and turn around from the side surface to wash the rear surface. To do.

  As described above, in the first embodiment shown in FIG. 6, the car wash machine main body 1 is moved back and forth while the car CA to be cleaned is stopped at a predetermined car wash position. In addition to this, as a configuration capable of reciprocating the vehicle to be cleaned CA using a conveyor device, a method of washing the vehicle so that it can be moved relative to the car wash machine body 1 even in a short installation space is adopted. ing. An example of this embodiment will be described with reference to FIG.

  The car wash machine WAa of the second embodiment shown in FIG. 7 is an example in which a conveyor device 40 that conveys the vehicle to be cleaned CA is provided between the pair of left and right rails 2 and 2. The conveyor device 40 has a pair of left and right conveyors on which left and right tires are placed. In the car wash machine WAa having such a configuration, the car to be washed CA stopped on the conveyor can be reciprocated by the conveyor device 40, and therefore, even in a narrow installation space, the car wash machine main body 1 is used for a series of operations. It is preferable because the car washing process can be executed. The conveyor device 40 includes a drive shaft 41 and a driven shaft 42, and rotates the drive shaft 41 via a drive motor (not shown) to move the vehicle to be cleaned CA stopped on the conveyor to perform car washing. . That is, the vehicle to be cleaned CA is reciprocated to relatively move the car wash machine body 1 and the vehicle to be cleaned CA.

  In the second embodiment, the installation position of the lower surface cleaning device WC is limited between the left and right conveyors. For this purpose, traveling rails 32, 32 are installed between the left and right conveyors, and the traveling carriage 30 travels on this. That is, the space between the left and right conveyors of the conveyor device 40 is a movable region of the lower surface cleaning device WC.

  Further, since it is preferable not to interfere with the drive shaft 41 and the driven shaft 42 at the limit position in the longitudinal direction of the movable region, the inner region between both shafts is set as the movable region of the lower surface cleaning device WC. That is, when the conveyor device 40 for transporting the vehicle to be cleaned CA is provided, the lower surface cleaning device WC is installed in the region between the left and right conveyors and between the front and rear shafts, and this region is made a movable region of the lower surface cleaning device WC. Set.

  Even if the lower surface cleaning apparatus WC of the present embodiment is configured as described above, the entire lower surface of the vehicle CA to be cleaned can be reliably cleaned, and the installation layout of the car wash machine and the conveyor device can be used. It can be arranged without being affected.

  Next, the configuration and cleaning operation of the lower surface cleaning apparatus WC will be described with reference to FIGS. The car wash machine described here is based on a car wash machine WA of the type in which the car wash machine body 1 travels and performs car wash without using the conveyor device 40.

  The user who wishes to wash the vehicle sets the vehicle to be washed CA toward the car wash machine main body 1A stopped at the predetermined standby position as shown in FIG. It moves in the direction shown and stops at a predetermined car wash position.

  As described above, the car wash machine main body 1 </ b> A is provided with the area sensor 9 and the side brush 5. Therefore, when the vehicle passes through the detection unit of the area sensor 9 and stops at a predetermined position, it is detected via the area sensor 9 that the vehicle to be cleaned CA has stopped at the car wash position.

  Further, the lower surface cleaning device WC stands by in the middle of the horizontal direction (front-rear direction) of the area sensor 9 and the side brush 5 provided in the car wash main body 1A. That is, the lower surface cleaning device WC stands by at a position away from the side brush 5 in the front-rear direction by the first separation distance L1. The standby position is a position away from the area sensor 9 by the second separation distance L2, and the area sensor 9 and the side brush 5 are separated from each other by a distance L (L1 + L2).

  After the vehicle to be cleaned CA stops at the car wash position, the car wash process is executed. First, as shown in FIG. 2, the car washer main body is moved in the direction indicated by the arrow D2 in the drawing, and the side brush 5 stops at a position where it abuts against the tip of the vehicle to be cleaned CA. That is, the car wash machine main body 1 </ b> B stopped at this position is in a state in which the front surface of the vehicle to be cleaned CA can be washed using the side brush 5.

  A conventionally known method is used as a method for detecting that the side brush 5 has come into contact with the tip of the vehicle CA to be cleaned. For example, it can be detected using a sensor that detects the inclination of the brush shaft 52 of the side brush 5 that is configured to be swingable via the swing support portion 51 and to be rotatable.

  The side brush 5 is rotated in a state where the side brush 5 is in contact with the tip of the vehicle 5 to be cleaned, and the front surface of the vehicle CA to be cleaned is washed. At this time, since the lower surface cleaning device WC is located at the lower part of the vehicle, the lower surface of the vehicle to be cleaned is cleaned by injecting cleaning water from the cleaning water injection nozzle.

  The pair of left and right side brushes 5 are gradually opened from the closed state while rotating, and the front surface of the vehicle CA to be cleaned is washed. Further, when the entire width of the vehicle is washed, when the vehicle reaches the side of the vehicle, the completion of the washing of the front portion is detected by the change in the inclination of the brush shaft 52. Thereafter, the rotation of the side brush 5 is stopped, and the car wash machine body is moved backward in the direction indicated by the arrow D3 as shown in FIG.

  That is, the lower surface cleaning device WC is moved toward the tip of the vehicle to be cleaned CA. During this backward movement, the cleaning water can be sprayed from the cleaning water spray nozzle to clean the lower surface of the vehicle to be cleaned that reaches the tip. Further, at this time, it is preferable that the structure is moved by a distance corresponding to the first separation distance L1, because even if sprayed continuously during the movement, cleaning water is not sprayed except at the lower surface of the vehicle CA to be cleaned.

  Further, even if this backward movement is a step of returning the car wash machine main body to the initial standby position, by limiting the injection from the washing water injection nozzle while moving the distance corresponding to the first separation distance L1, It is possible to adopt a configuration in which the cleaning water is not jetted in a region outside the vehicle to be cleaned CA, that is, other than the lower surface of the vehicle CA to be cleaned.

  Next, the lower surface cleaning device WC moves forward in the direction of the arrow D4 shown in FIG. 4 when the lower surface cleaning device WC is in a position to clean the tip of the cleaned vehicle CA, and the lower surface cleaning device WC The cleaning operation is continued up to the car wash machine main body 1D at the position for cleaning the rear end portion, and the entire lower surface of the vehicle CA to be cleaned is cleaned.

  At the position of the car wash machine main body 1D, the position of the lower surface cleaning device WC that is cleaning the rear end of the vehicle to be cleaned CA is a position away from the area sensor 9 by the second separation distance L2. That is, after detecting the position of the rear end portion of the vehicle CA to be cleaned via the area sensor 9, the rear end portion of the vehicle CA to be cleaned is moved using the lower surface cleaning device WC until the car wash machine body 1 is moved forward by the distance L2. If it is set as the structure wash | cleaned, only the lower surface part of the to-be-cleaned vehicle CA will be wash | cleaned correctly, and cleaning water will not be injected except the area | region which removed the to-be-cleaned vehicle CA, ie, the lower surface of the to-be-cleaned vehicle CA.

  Further, the car wash machine main body 1 is further moved forward, and the operation of washing the side surface and the rear surface of the vehicle CA to be cleaned using the side brush 5 is continued.

  Next, the area | region which wash | cleans the lower part of the to-be-cleaned vehicle CA using the lower surface washing | cleaning apparatus WC is further demonstrated using FIG.

  Since the lower surface cleaning apparatus WC is configured to reciprocate in conjunction with the car wash machine main body 1, the lower surface cleaning apparatus WC is located at the tip of the vehicle to be cleaned CA when the car wash machine main body is moving. From 1C to the car wash machine main body 1D located at the rear end of the vehicle to be cleaned CA, the lower surface cleaning device WC injects cleaning water to clean the lower surface of the vehicle CA to be cleaned.

  Further, in the traveling carriage 30 of the lower surface cleaning apparatus WC, the distance between the traveling carriage 30A and the side brush 5 at the position for cleaning the front end portion of the vehicle to be cleaned CA is separated from the first separation distance L1. The distance between the traveling carriage 30B at the position for cleaning the rear end portion and the area sensor 9 is separated from the second separation distance L2.

  Therefore, the distance L2 from the state where the area sensor 9 detects the rear end of the vehicle CA to be cleaned from the position where the car wash machine main body is moved backward by the distance L1 from the state in which the side brush 5 is in contact with the tip of the vehicle CA to be cleaned. The area up to the position where the main body of the car washer is advanced is the cleaning area of the lower surface cleaning device WC.

  That is, the first separation distance L1 that is the distance in the front-rear direction between the lower surface cleaning device WC and the side brush 5 and the second separation distance L2 that is the distance in the front-rear direction between the lower surface cleaning device WC and the area sensor 9 are preliminarily set. The front end cleaning start position of the lower surface cleaning device WC is defined according to the first separation distance L1, and the rear end cleaning stop position of the lower surface cleaning device WC is defined according to the second separation distance L2.

  If it is said structure, even when installing the lower washing | cleaning apparatus WC newly after installing a car wash machine main body and a conveyor apparatus, the employ | adopted 1st separation distance L1 and 2nd separation distance L2 are newly set. Thus, the lower washing apparatus WC can be driven in conjunction with the car wash machine body 1, and the vehicle between the front and rear ends of the vehicle to be washed detected by the side brush 5 and the area sensor 9 provided in the car wash machine body 1. The lower part can be reliably cleaned.

  As described above, the car wash machine WA according to the present embodiment is a car wash machine having a lower surface cleaning device for cleaning the lower surface of the vehicle to be cleaned, even if it has a simple configuration without a pulse sensor. A car washer that can be installed without being affected by the installation layout of the main body and conveyor device, and that can wash the entire bottom surface of the vehicle without spraying washing water and leaving no washing residue other than the bottom surface of the vehicle to be cleaned. Become.

  Further, the lower surface cleaning apparatus includes a return step for moving from the standby position to the front end portion of the vehicle to be cleaned and a forward step for moving from the front end portion to the rear end portion of the vehicle to be cleaned, and the lower surface injection is performed during the forward step. Since the cleaning operation is performed by injecting the cleaning water from the nozzle, it is possible to reliably clean from the front end portion to the rear end portion of the vehicle to be cleaned, and no unwashed residue is generated.

  Further, a first separation distance that is a distance in the front-rear direction (horizontal direction) between the lower surface cleaning device and the side brush at the standby position, and a second separation distance that is a distance in the front-rear direction between the lower surface cleaning device and the area sensor, Is stored in advance, the front end cleaning start position of the lower surface cleaning apparatus is defined according to the first separation distance, and the rear end cleaning stop position of the lower surface cleaning apparatus is defined according to the second separation distance. Therefore, the lower part of the vehicle between the front and rear ends of the vehicle to be cleaned, which is detected by the side brush and the area sensor provided in the car wash machine main body, can be reliably cleaned.

  Therefore, the car wash machine according to the present invention is required to wash the lower part of the vehicle to be washed using the lower surface washing device that can be arranged without being affected by the installation layout of the car wash machine body and the conveyor device. It is suitably applied to car wash machines.
