[Problems to be solved by the invention]
However, in the conventional vehicle cleaning apparatus, since the injection direction of the upper surface cleaning nozzle can be changed only in three directions, downward, front, and rear, when the injection direction changes when the upper surface cleaning nozzle moves up and down, There has been a problem that a portion where the washing water is not sufficiently jetted to the vehicle to be washed occurs.
[0005]
Accordingly, an object of the present invention is to provide a vehicle cleaning apparatus that can always sufficiently inject cleaning water onto a vehicle to be cleaned and has an excellent cleaning finish.
[0006]
[Means for Solving the Problems]
  In order to achieve the above-described object, the invention according to claim 1 of the present invention is a vehicle provided in a car wash machine that performs a car wash on the car to be cleaned while relatively moving the vehicle to be cleaned and the car wash machine body. A cleaning device,
  A spray device capable of swinging in the relative movement direction a nozzle for injecting cleaning water or detergent into the vehicle to be cleaned;A control device that controls the overall operation of the car wash machine body and that can execute the swing control of the nozzle of the spray device,
When the controller performs cleaning between the front end portion and the rear end portion of the vehicle to be cleaned, the nozzle of the spray device sprays cleaning water or detergent at a right angle to the upper surface of the vehicle to be cleaned. Based on the relative movement position of the vehicle to be cleaned and the car wash machine main body, when constantly washing in the relative movement direction around the position and performing cleaning at the front end and the rear end of the vehicle to be cleaned, Limiting the swinging motion of the nozzle of the spray device in one of the relative movement directionsIt is characterized by this.
[0007]
According to the above configuration, when the vehicle to be cleaned is cleaned while relatively moving the vehicle to be cleaned and the car wash machine main body, the nozzle for injecting the cleaning water or the detergent to the vehicle to be cleaned is always swung in the relative movement direction. . Therefore, there is no portion where the high-pressure water is not jetted on the upper surface of the vehicle to be cleaned, and no washing is left.
[0009]
  AlsoAccording to the above configuration, the oscillation center of the nozzle is set to the inclined position where the cleaning water or the detergent is injected at a substantially right angle with respect to the upper surface of the vehicle to be cleaned. Therefore, the high-pressure water is efficiently injected onto the upper surface of the vehicle to be cleaned without reducing the pressure of the water, and the high-pressure water is reduced from being unnecessarily injected to the vehicle to be cleaned, so that the car can be washed with a small amount of water. .
[0011]
  AlsoAccording to the above configuration, the swinging operation of the nozzle can be limited so that the high-pressure water sprayed from the nozzle of the spray device is not sprayed to other than the vehicle to be cleaned. Therefore, since no high-pressure water is injected into a place where the vehicle to be cleaned does not exist, unnecessary high-pressure water is not injected.
[0012]
  And claims2The invention described in claim 11The spray device nozzle can be moved up and down,By giving the control device a function of raising and lowering the nozzle of the spray device,The vehicle is moved up and down in accordance with the vehicle height of the vehicle to be cleaned.
[0013]
According to the said structure, a nozzle is raised / lowered according to the vehicle height of a to-be-cleaned vehicle. Therefore, high-pressure water can be injected to the vehicle to be cleaned without dropping the water pressure most, and the car wash is executed with a small amount of high-pressure water, thereby improving the efficiency.

Further, the lift distance detection unit 93 obtains the lift distance ys of the high-pressure water spray nozzle 11 from the floor surface 4.
[0035]
When the high-pressure water spray command signal is turned on, the high-pressure pump 73 is driven, and the elevation distance ys output from the elevation distance detection unit 93 is fed back to the height H output from the height setting unit 94. The raising / lowering electric motor 64 is driven, and the high pressure water spray nozzle 11 is raised / lowered to a height H, that is, a position β above the upper surface of the vehicle 2. In addition, when the upper limit detection sensor 83 operates, the increase is stopped, and when the lower limit detection sensor 84 operates, the decrease is stopped.

Subsequently, the front main body 1A moves backward, and the side brush 18 is vertical as shown in FIG. The vehicle stops when it comes into contact with the posture, and the front surface of the vehicle 2 is cleaned by the side brush 18.
[0047]
Subsequently, a reverse command for the front body 1A is output so that the top brush 14 is positioned at the tip of the vehicle 2 (step-16), and a lowering command for the top brush 14 is output (step-17).
[0048]
As a result, the front main body 1 </ b> A moves backward and the top brush 14 is lowered toward the vehicle 2.
When it is confirmed that the top brush 14 is located at the tip position of the vehicle 2 by the reverse travel distance of the front main body 1A (step -18), a stop command for the front main body 1A is output (step -19).
[0049]
As a result, as shown in FIG. 14 (e), the front body 1 </ b> A stops with the top brush 14 positioned at the tip of the vehicle 2. At this time, the side brush 18 is in an open state, and the distance between the front main body 1A and the rear main body 1B is reduced by the distance traveled by the front main body 1A.
[0050]
Subsequently, a car wash command signal is output to the top brush 14 and the side brush 18 (step-20), and a forward command for the front body 1A is output (step-21).
As a result, as shown in FIG. 14F, the front main body 1A starts moving forward while the top brush 14 and the side brush 18 are cleaning the upper surface and both side surfaces of the vehicle 2. Further, when the front main body 1A moves forward and leaves the set separation distance L (step -22), a forward command for the rear main body 1B is output (step -23).
[0051]
Thereby, as shown in FIG.14 (g), the movement of the rear part main body 1B is started.
Subsequently, a blow command for the blower device 33 of the drying nozzles 31 and 32 is output (step -24), and a drive command for the drying nozzles 31 and 32 is output (step -25).
[0052]
Accordingly, as shown in FIGS. 14 (h) and 15 (i), the top nozzle 31 is lowered to the tip of the vehicle 2, and drying of the upper surface and both side surfaces of the vehicle 2 by the drying nozzles 31 and 32 is started. . At this time, the vehicle 2 is washed with the brushes 13, 14, 18, and the distance between the brushes 13, 14, 18 and the drying nozzles 31, 32 is set to a set separation distance (maximum separation distance) L. . As shown in FIG. 14 (h), when the high-pressure water spray nozzle 11 moves to the rear end of the vehicle 2, the solenoid valve 74 is closed and the injection of high-pressure water is stopped.
[0053]
Subsequently, when the side brush 18 moves to the back of the vehicle 2 and turns to the back to finish cleaning the back of the vehicle 2 (step-26), a stop command for the front body 1A is output (step-27). A drive stop command is output to each brush 13, 14, 18 and the high pressure water spray command signal is turned off (step -28).
[0054]
As a result, as shown in FIG. 15 (j), the front main body 1A is stopped in a state where the side brush 18 is located on the back surface of the vehicle 2, the driving of the brushes 13, 14, 18 is stopped, and a high pressure water spray command is issued. In response to the signal being turned off, the high-pressure pump 73 is stopped. Further, as shown in FIG. 15 (k), the rear main body 1B continues to move forward while the drying of the vehicle 2 by the drying nozzles 31 and 32 is executed.
[0055]
Subsequently, as shown in FIG. 15 (l), when the rear main body 1B approaches the front main body 1A and the operation of the closing limit deceleration detection sensor 38 is confirmed (step -29), a forward command for the front main body 1A is output. (Step-30).
[0056]
Thereby, both the front main body 1A and the rear main body 1B continue to advance.
When it is confirmed by the operation of the front main body EP detection sensor 28 that the front main body 1A has reached the end position (travel end position) (step-31), the forward command of the front main body 1A is turned off, that is, When a stop command is output (step-32) and it is confirmed by the operation of the rear main body EP detection sensor 35 that the rear main body 1B has reached the end position (travel end position) (step-33), the rear main body 1B moves forward. The command is turned off, that is, a stop command is output (step-34), and a drive stop command for the drying nozzles 31, 32 and the blower device 33 is output (step-35).
[0057]
As a result, as shown in FIG. 15 (m), both the front main body 1A and the rear main body 1B are stopped at the end positions, and the driving of the drying nozzles 31, 32 and the blower device 33 is stopped.
[0058]
Subsequently, a lighting command is output to the exit signal lamp 53 (step-36).
As a result, the exit signal lamp 53 is turned on, and the driver of the vehicle 2 leaves the vehicle 2 as shown in FIG.
[0059]
Subsequently, when the exit of the vehicle 2 is confirmed (step-37), a turn-off command is output to the exit signal lamp 53 (step-38), and reverse commands of the front main body 1A and the rear main body 1B are output (step-39).

The confirmation of the exit of the vehicle 2 is confirmed, for example, by an operation of a sensor or the like that detects that the wheel of the vehicle 2 has moved.
[0060]
As a result, as shown in FIG. 15 (o), both the front main body 1A and the rear main body 1B return to the home position.
Subsequently, the vehicle 2 is stopped in front of the breaker 51 by the ingress sensor 52, and the vehicle height is equal to or lower than an allowable height at which the vehicle can enter the car wash machine main body 1 (front main body 1A, rear main body 1B). Is confirmed (step-44), an opening command is output to the circuit breaker 51 (step-45), the entry indicator lamp 24 is turned on (step-46), and it is prepared for the next car wash.
[0061]
As a result, as shown in FIG. 15 (p), the circuit breaker 51 is opened and the next vehicle 2 is allowed to enter.
When the vehicle height of the vehicle 2 is unacceptable in step -44, the stop indicator lamp 25 blinks to notify that the vehicle cannot be washed (step -47). This notification is continued while the vehicle 2 is detected by the approach sensor 52.
[0062]
In this way, the front main body 1A and the rear main body 1B are separately driven, and as shown in FIGS. 14 (h), 15 (i), and 15 (j), the cleaning means being cleaned and the drying are being performed. The distance from the drying means can be separated to the maximum distance (set separation distance) L, and therefore, it is possible to prevent the drying from being hindered by the spraying of water during washing, and the finish of the drying can be always good. Moreover, it is possible to prevent the washing from being hindered by the air blowing during the drying, and the washing can be always good.
[0063]
As described above, according to the present embodiment, when the vehicle 2 is washed while the vehicle 2 and the car wash machine body 1 are relatively moved, the nozzle 11 of the high-pressure water spray device 56 is always swung in the relative movement direction. As a result, there are no locations where high-pressure water is not sprayed onto the upper surface of the vehicle 2 (locations where unwashed parts are likely to be generated), so that washing can be performed evenly and the finish of the car wash can be improved.
[0064]
Further, according to the present embodiment, the nozzle 11 of the high-pressure water spray device 56 is swung around the position where the high-pressure water is injected at a substantially right angle with respect to the upper surface of the vehicle 2, that is, the high-pressure water spray nozzle 11. By setting the swing center to an inclined position where high-pressure water is injected at a substantially right angle with respect to the upper surface of the vehicle 2, the high-pressure water can be efficiently injected onto the upper surface of the vehicle to be cleaned without dropping the water pressure. Can be reduced, and the vehicle can be washed with a small amount of water.
[0065]
Moreover, according to this Embodiment, based on the relative movement position of the vehicle 2 and the car wash machine main body 1, the high pressure water sprayed from the nozzle 11 of the high pressure water spray device 56 is prevented from being sprayed to other than the vehicle 2. By restricting the swinging operation, it is possible to eliminate the injection of high-pressure water to a place where the vehicle 2 does not exist, and to eliminate unnecessary high-pressure water injection, so that the car can be washed with a small amount of water.
[0066]
Further, according to the present embodiment, the high pressure water spray nozzle 11 is raised and lowered in accordance with the vehicle height of the vehicle 2, so that even if the vehicle 2 has a low vehicle height, the high pressure water is not wasted. The high pressure water can be injected into the vehicle 2 without reducing the pressure of the water, and the reduction of the cleaning efficiency can be reduced.
[0067]
Further, according to the present embodiment, the vehicle 2 and the car wash machine main body 1 are relatively moved, while the vehicle 2 is cleaned by the cleaning means provided on the front main body 1A and the vehicle 2 by the drying means provided on the rear main body 1B. Since the drying is performed separately, even if the cleaning means and the drying means are driven simultaneously, the drying means is not affected by the splash of water generated during the cleaning, and the cleaning means Since it is not affected, it is possible to prevent the finish of the car wash from being deteriorated. Further, by simultaneously driving the washing means and the drying means, the car wash can be completed in one forward path, the car wash time can be shortened, and the car wash efficiency can be improved.
[0068]
In the present embodiment, the swinging motion of the nozzle 11 of the high-pressure water spray device 56 is limited based on the relative movement position of the vehicle 2 and the car wash machine body 1, that is, as shown in FIG. Although it is limited in accordance with the position of the vehicle 2 existing at the position of the high-pressure water spray nozzle 11, as shown in FIG. 16, three sections K 1 forward from the point where the front body 1 A is located at the home position HP. , K2 and K3 are set in advance, the first section forward, for example, the section K1 having a distance of 1.5 m is set as a section for restricting the backward swing of the nozzle 11, and the next section, for example, the section K2 having a distance of 2.5 m is set. It is also possible to limit the swinging motion of the nozzle 11 by setting the section without restriction and the last section forward, for example, the section K3 having a distance of 1.0 m as the section for limiting the forward swing of the nozzle 11. At this time, when the front body 1A starts moving forward from the HP, the backward movement of the nozzle 11 is limited and the forward movement is detected only by the forward distance detection unit 91 (FIG. 10). When x is 1.5 m, the nozzle 11 is once fixed in a vertical posture, then swung without restriction of the nozzle 11, and then continuously moved for 2.5 m, after the nozzle 11 is once fixed in a vertical posture. The nozzle 11 is limited to swing forward and swings only backward. In this manner, the swing control can be simplified by restricting the swing operation of the nozzle 11 by the travel position (travel distance x) of the front main body 1A regardless of the vehicle shape and vehicle type of the vehicle 2. .
[0069]
In the present embodiment, the high-pressure water spray nozzle 11 stores the vehicle height detected by the equipment discrimination device 41 and obtains the height hs of the vehicle 2 corresponding to the actual position of the high-pressure water spray nozzle 11. Although it is lifted / lowered in accordance with the height hs of the vehicle 2, the lifting / lowering control of the nozzle 11 can be simplified. For example, as shown in FIG. 17, an L-shaped fixture 89A is provided in front of the tip from the left and right ends of the frame 60, and the length from the nozzle 11 is set to β (the height hs is set in advance). The support member 89 having a margin β) is suspended, the vertical member a of the fixture 89A is provided with two transmission photoelectric sensors 90A and 90B on the top and bottom, and the horizontal member b has the same height as the transmission photoelectric sensor 90B. A transmissive photoelectric sensor 90C is provided, and the high-pressure water spray nozzle 11 is moved up and down in response to detection of the vehicle 2 by the transmissive photoelectric sensors 90A, 90B, and 90C. At this time, when the front body 1A starts moving forward, the high pressure water spray nozzle 11 (frame body 60) is lowered, and the vehicle 2 is detected by the transmission photoelectric sensors 90A, 90B, 90C. The body 60 is raised and lowered a little after a certain period of time. When the vehicle 2 is detected, the frame 60 is raised until it is not detected again. As a result, the nozzle 11 can be moved up and down in accordance with the detection signals of the transmission photoelectric sensors 90A, 90B, and 90C, and the nozzle 11 can be easily positioned at the margin value β from the upper surface of the vehicle 2 without detecting the vehicle height of the vehicle 2. Can be maintained with good control.
[0070]
As shown in FIG. 18, when the vehicle 2 passes and the front main body vehicle detection sensor 42 is turned off and the vehicle 2 is not detected, the nozzle 11 is fixed to the vehicle 2 in a backward inclined posture (45 ° rearward). At the same time, the traveling speed of the front main body 1A can be reduced. At this time, the transmissive photoelectric sensors 90A, 90B, and 90C no longer detect the vehicle 2 and the nozzle 11 descends, so that high-pressure water can be injected from the nozzle 11 to the rear portion of the vehicle 2. Therefore, when the rear part of the vehicle 2 is nearly vertical like a wagon car, high-pressure water can be effectively injected from the nozzle 11. At this time, if the front main body vehicle detection sensor 42 is turned off and moves forward at a low speed for a certain distance, for example, 500 mm, the traveling is stopped, the nozzle 11 is raised, and the posture of the nozzle 11 is returned to the vertical posture and fixed. When the nozzle 11 is raised to the upper limit, the front body 1A can be moved backward.
[0071]
Further, in the present embodiment, only the nozzle 11 of the high-pressure water spray device 56 is moved up and down in accordance with the vehicle shape of the vehicle 2, swings in accordance with the relative movement position of the vehicle 2 and the car wash machine body 1, and further, The center of oscillation is set so as to be substantially perpendicular to this angle γ according to the inclination angle γ, but the nozzles of the first and second cleaning water arches 12 and 16 for spraying the cleaning water, the detergent being sprayed or The nozzles of the first and second detergent arches 15 and 21 to be sprayed are moved up and down in accordance with the vehicle shape of the vehicle 2, swinging according to the relative movement position of the vehicle 2 and the car wash machine body 1, and the inclination angle of the vehicle upper surface According to γ, the center of oscillation can be set to be substantially perpendicular to the angle γ, and the washing water or the detergent is not sprayed on the upper surface of the vehicle 2 like the nozzle 11 of the high-pressure water spray device 56. (Locations where washing is likely to occur) It is possible to clean evenly, improve the finish of the car wash, reduce the wasteful injection of wash water or detergent onto the vehicle 2, and perform the car wash with a small amount of water. In addition, even if the vehicle 2 has a low vehicle height, it can be sprayed onto the vehicle 2 without wasting cleaning water or detergent, and a reduction in cleaning efficiency can be reduced.
[0072]
Further, in the present embodiment, in the swing center setting unit 99, the swing center is substantially perpendicular to the vehicle upper surface tilt angle γ according to the vehicle upper surface tilt angle γ determined by the tilt setting unit 96. The center of swing is set to 45 ° backward, center and 45 ° forward, but the angle perpendicular to the vehicle upper surface tilt angle γ is obtained by adding 90 ° to the vehicle upper surface tilt angle γ. It is also possible to drive the swinging electric motor 58 to swing accurately and to swing back and forth from this rotational position. At this time, a pulse sensor disk is pivotally supported on the high-pressure water pipe 57 to which the nozzle 11 is attached, a pulse sensor is arranged opposite to the disk, and the nozzle 11 is counted by counting pulses output from the pulse sensor. By obtaining the swing angle of the attached high-pressure water pipe 57 and feeding back this swing angle, the swing center of the nozzle 11 can be made perpendicular to the inclination angle γ of the upper surface of the vehicle.
[0073]
Further, in the present embodiment, the car washer is configured such that the front main body 1A provided with the cleaning means and the rear main body 1B provided with the drying means can be moved separately, but the front main body 1A and the rear main body 1B are integrated. It can also be set as the normal car wash machine comprised in this. The car wash machine body 1 (front main body 1A and rear main body 1B) is moved to move the car wash machine body 1 and the vehicle 2 relative to each other to wash the vehicle 2. However, the roller conveyor (vehicle moving means) is used. It is possible to move the vehicle 2 back and forth using the, and move it relative to each other, and further move the front main body 1A and the rear main body 1B while approaching and separating them, and using a roller conveyor (vehicle moving means) It is also possible to move the vehicle 2 back and forth and make a relative movement.
[0074]
Further, in the present embodiment, the high-pressure water spray nozzle 11 is lifted and lowered by the driving force of the electric motor (the lifting electric motor 64, the swinging electric motor 58), but is not limited to the electric motor. You may make it raise / lower and swing using pneumatic pressure or hydraulic pressure of a cylinder or the like.
[0075]
In this embodiment, the travel distance x is detected by the travel distance detector 91 that counts the pulses of the front body encoder 46, and the lift distance y is detected by the lift distance detector 93 that counts the pulses of the pulse sensor 77. However, the present invention is not limited to the encoder 46, the pulse sensor 77, the travel distance detector 91, and the lift distance detector 93, and the travel distance x and the lift distance y are detected using a distance measuring device using light. You may make it do.
[0076]
