Therefore, even if the cleaning means and the drying means are driven at the same time, the drying by the drying means is hindered by the splash of water generated during the cleaning. It can be prevented, and the washing by the washing means can be prevented from being hindered by the influence of the air blown by the drying means, so that the finish of the car wash can be prevented from being deteriorated, and good washing can always be performed. .

  In addition, when the rear body starts running, it falls in the front-rear direction due to inertial force, or when the rear body that has traveled stops, it falls into the front-rear direction due to inertial force. When the main body is slightly tilted in the front-rear direction (approaching to be tilted), the auxiliary wheel body comes into contact with and supports the rail from above, and further tilting can be prevented. At this time, when the falling force is large, the auxiliary wheel rolls on the rail and can support the rear body while running a little. Furthermore, when the rear body is running, since the auxiliary wheel body is in a fitted state (guide state) with a gap to the rail, when the rear body is shaken in the left-right direction, the auxiliary wheel body is Since it comes into contact with the opposing rail surface, it can be prevented from being shaken more than that, and thus the rear main body can be prevented from derailing, and stable running can always be performed.

  As described above, the rear main body can be prevented from falling by the support function of the auxiliary wheel body while maintaining the light weight and the low cost by adding a simple structure where the auxiliary wheel body is provided. The guide action can prevent derailment.

  According to the second aspect of the present invention described above, the vehicle to be cleaned is cleaned by the cleaning means provided on the front body and the drying means provided on the rear body while the car wash machine body is moved relative to the vehicle to be cleaned. Therefore, even if the cleaning means and the drying means are driven at the same time, the drying by the drying means is hindered by the splash of water generated during the cleaning. In addition, it is possible to prevent the cleaning by the cleaning means from being hindered by the influence of the air blow of the drying means, and thus it is possible to prevent the finish of the car wash from being deteriorated, and always perform good cleaning. it can.

  When the front main body and the rear main body stop at the home position (travel start position) and the front main body is approaching the rear main body, the projecting body leaves a gap with respect to the receiving surface from above. Opposite. In such a state, the rear main body that is stopped at the home position falls backward due to inertial force when starting to advance, or rearward due to inertial force when the rear main body that has been moved backward is stopped at the home position. In these cases, when the rear body is tilted slightly backward (in a state of falling down), the front part of the rear body is lifted to absorb the gap, thereby The receiving surface comes into contact with the projecting body from below, and the rear main body is supported by the front main body, so that the rear main body can be prevented from falling further.

  In this way, the rear body is light and inexpensive while maintaining the light weight and low cost by adding a simple configuration where the front body is provided with a projecting body facing from above with a gap in the receiving surface formed on the rear body. In addition, it is possible to prevent the fall by the support action by the receiving surface coming into contact with the protruding body from below.

  According to claim 3 of the present invention described above, when there is a foreign object such as a hose on the rail, for example, when the rear body is running, the scraper comes into contact with the foreign object and pushes it on the rail. Therefore, it is possible to prevent foreign objects from being caught by the driven wheel body and the auxiliary wheel body (driving wheel body), and it is possible to always perform stable traveling.

  Further, according to the fourth aspect of the present invention described above, when the rear body is slightly inclined in the front-rear direction (approaching to fall), the idle roller is supported by contacting the left and right inclined surfaces of the rail from above. It can prevent further collapse. In addition, when the rear body is swung in the left-right direction, one of the idle rollers comes into contact with the opposing left and right inclined surfaces, and can be prevented from being swung more than that. Thus, the rear main body can be prevented from derailing, and stable running can always be performed.

An open command is output (step -14).

  As a result, the front main body 11 moves forward and stops by a signal from the vehicle body detection sensor. Subsequently, the front main body 11 moves backward, and the side brush 28 moves relative to the front surface of the vehicle 1 as shown in FIG. It stops when it comes into contact with a suitable surface pressure, and the front surface of the vehicle 1 is cleaned by the side brush 28.

  Subsequently, the backward movement command of the front body 11 is output to the traveling control unit so that the top brush 24 is positioned at the tip of the vehicle 1 (step -15), and the lowering command of the top brush 24 is output to the cleaning control unit ( Step-16). As a result, the front main body 11 moves backward and the top brush 24 descends toward the vehicle 1.

  When it is confirmed that the top brush 24 is located at the tip position of the vehicle 1 based on the travel distance of the front body 11 (step -17), a stop command for the front body 11 is output to the travel control section (step -18). . As a result, as shown in FIG. 8 (e), the front body 11 stops in a state where the top brush 24 is positioned at the tip of the vehicle 1. At this time, the side brush 28 is in an open state, and the distance between the front main body 11 and the rear main body 41 is reduced by the distance traveled by the front main body 11.

  Subsequently, a car wash command signal for the top brush 24 and the side brush 28 is output to the cleaning control unit (step-19), and a forward command for the front body 11 is output to the travel control unit (step-20). As a result, the front body 11 starts moving forward while the top brush 24 and the side brush 28 are used to clean the upper surface and both side surfaces of the vehicle 1.

  Further, when the front main body 11 moves forward and moves away from the set separation distance (maximum separation distance) L as shown in FIG. 8 (f), a separation distance detection signal is input from the travel control section (step -21). A forward command for the rear body 41 is output to the travel control unit (step -22). Thereby, the movement of the rear main body 41 is started as shown in FIG. As a result, the front main body 11 and the rear main body 41 move forward together with the maximum set separation distance L provided between the front main body 11 and the rear main body 41 by the travel control unit. At this time, the brush 23 , 24, and 28, and the distance between the brushes 23, 24, and 28 and the nozzles 56 and 57 is set to a set separation distance (maximum separation distance) L.

  Subsequently, the blowing command of the blower device 58 of the drying nozzles 56, 57 is output to the drying control unit (step -23), and the driving command of the nozzles 56, 57 is output to the drying control unit (step -24). As a result, as shown in FIG. 8 (h), the top nozzle 56 is lowered to the tip of the vehicle 1, and drying of the upper surface and both side surfaces of the vehicle 1 by the drying nozzles 56 and 57 is started.

  Thereafter, as shown in FIG. 9 (i), when the side brush 28 moves to the back surface of the vehicle 1 and turns to the back surface to finish cleaning the back surface of the vehicle 1 (step-25), each of the control units is sent to the cleaning control unit. A drive stop command is output to the brushes 23, 24, and 28 (step -26), whereby the drive of the brushes 13, 14, and 18 is stopped.

  Then, as shown in FIG. 9 (j), after the front main body 11 moves forward, it is confirmed that the front main body 11 has reached the end position (travel end position) by the operation of the front main body EP detection sensor 37. (Step-27), the forward command of the front body 11 that has been output to the travel control unit is turned off, that is, a stop command is output (Step-28), and as shown in FIG. The front main body 11 is stopped in a state where it is positioned. At this time, the rear main body 41 continues to advance while the drying of the vehicle 1 by the drying nozzles 56 and 57 is executed.

  Subsequently, when it is confirmed by the operation of the rear body stop means 70 that the rear body 41 has reached the end position (travel end position) (step -29), the forward command of the rear body 41 output to the travel control unit is turned off. That is, a stop command is output (step-30), and a drive stop command for the drying nozzles 56 and 57 and the blower device 58 is output to the drying control unit (step-31). As a result, as shown in FIG. 9 (l), both the front main body 11 and the rear main body 41 stop at the end positions, and the driving of the nozzles 56 and 57 and the blower device 58 is stopped.

  Subsequently, a lighting command is output to the exit signal lamp 7 (step -32). As a result, the exit signal lamp 7 is turned on, and the driver of the vehicle 1 leaves the vehicle 1 as shown in FIG. Subsequently, when the exit of the vehicle 1 is confirmed (step-33), a turn-off command is output to the exit signal lamp 7 (step-34), and a reverse drive command for the front main body 11 and the rear main body 41 is output to the travel control unit (step-34). -35).

  Then, when it is confirmed that the front main body 11 has reached the home position by the operation of the front main body HP detection sensor 36 (step -36), the reverse command of the front main body 11 output to the traveling control unit is turned off. That is, a stop command is output (step-37), and when it is confirmed by the operation of the rear main body HP detection sensor 60 that the rear main body 41 has reached the home position (step-38), it is output to the travel control section. Then, the reverse command of the rear body 41 is turned off and a stop command is output (step-39). The confirmation of the exit of the vehicle 1 is confirmed, for example, by the operation of a sensor or the like that detects that the wheel of the vehicle 1 has moved. Thereby, as shown in FIG.9 (n), both the front main body 11 and the rear main body 41 return to a home position.

  Subsequently, the vehicle 1 is stopped in front of the breaker 5 by the ingress sensor 6, and the vehicle height is equal to or lower than an allowable height at which the vehicle can enter the car wash machine body 10 (the front body 11 and the rear body 41). (Step-40), an open command is output to the circuit breaker 5 (Step-41), the entry indicator lamp 34 is turned on (Step-42), and it is prepared for the next car wash. As a result, as shown in FIG. 9 (o), the circuit breaker 5 is opened and the next vehicle 1 is allowed to enter.

  When the vehicle height of the vehicle 1 is unacceptable in step -42, the stop indicator lamp 35 is blinked to notify that the vehicle cannot be washed (step -43). This notification is continued while the vehicle 1 is detected by the approach sensor 6. In Step 1, when the vehicle 1 that has entered the car wash position has an unacceptable width and the vehicle 1 stops at an unacceptable position, it is similarly notified that the car cannot be washed.

  When an abnormal stop signal is input from the travel control unit based on an abnormal stop or failure of the travel motor, an operation stop command is output to the cleaning control unit and the drying control unit, and the operation of all the car wash machines is stopped. .

  In this way, the front main body 11 and the rear main body 41 are separately driven to run, and as shown in FIGS. 8 (h), 9 (i), and 9 (j), the cleaning means 20 during cleaning and the drying are dried. The distance between the vehicle and the drying means 55 can be increased to the maximum distance (set separation distance) L, that is, the vehicle 1 is cleaned by the cleaning means 20 provided on the front body 11 and the drying provided on the rear body 41. Drying of the vehicle 1 by means 55 can be carried out remotely.

  As a result, even if the cleaning means 20 and the drying means 55 are driven at the same time, it is possible to prevent the drying by the drying means 55 from being hindered by the influence of the spray generated during the cleaning, and the cleaning by the cleaning means 20. However, since it is possible to prevent obstruction due to the influence of the air blown by the drying means 55, it is possible to prevent the finish of the car wash from being deteriorated and always perform good washing. Further, by simultaneously driving the cleaning means 20 and the drying means 55, 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.

  During the traveling of the rear main body 41 as described above, for example, if there is a foreign object such as a hose on the rail 3, the scrapers 49 and 50 come into contact with the foreign object in advance to move it on the rail 3. Therefore, the foreign object can be prevented from being caught by the driven wheel body 43 and the idler roller 48 (drive wheel body 42), and stable running can be performed at all times.

  Further, when the rear main body 41 is running, both the idler rollers 48 are in a fitted state (guide state) with a clearance S between the left and right inclined surfaces 3a of the rail 3, so that the rear main body 41 is in the left-right direction. When one of the free-rolling rollers 48 is abutted against the left and right inclined surfaces 3a facing each other, it can be prevented from being shaken more than that. Prevents derailment, and can always run stably.

  Further, since the rear body 41 is provided with the blower device 58 and the like of the drying means 55 at the upper part and the center of gravity is at the upper part, when the rear body 41 stopped at the home position is advanced, the rear body 41 falls backward due to inertial force. When the rear main body 41 that has been moved backward or stopped at the home position, the rear main body 41 falls backward due to inertial force. In these cases, the rear main body 41 slightly tilts backward from the state of the phantom line in FIG. As shown by the solid line in FIG. 5, the idler roller 48 comes into contact with and supports the left and right inclined surfaces 3 a of the rail 3 from above to prevent further collapse. Can do. In this case, when the tilting force is large, the idle roller 48 rolls on the left and right inclined surfaces 3a and supports the rear body 41 while moving backward a little.

In such a case, the rear scraper 50 is not in contact with the left and right inclined surfaces 3a and is not damaged because the gap SS is larger than the gap S of the idler roller 48.
As described above, the rear main body 41 can be prevented from falling by the support action of the idle roller 48 while maintaining the light weight and the low cost by the simple addition of the configuration where the idle roller 48 is provided. The guide action of the rolling roller 48 can make it possible to prevent derailment.

When the rear main body 41 stopped at the end position is moved backward, it is tilted forward by an inertial force, or when the rear main body 41 that has advanced is stopped at the end position, it is tilted forward by an inertial force. However, in these cases, the rear main body 41 is located close to the front main body 11, so that it is received by the front main body 11 in the worst case.
[Embodiment 2]
Next, a second embodiment of the present invention will be described with reference to FIGS.

  This Embodiment 2 is a car wash machine that performs a car wash on the vehicle 1 while moving the car wash machine body 10 relative to the vehicle (vehicle to be cleaned) 1 in the same manner as the Embodiment 1 described above. The car washer main body 10 is separated into a front main body 11 having a cleaning means 20 for cleaning the vehicle 1 and a rear main body 41 having a drying means 55 for drying the vehicle 1. The rear main body 41 is supported and guided by the left and right rails 3 on the floor 2 side through the drive wheel bodies 12 and 42 and the driven wheel bodies 13 and 43 distributed in the front and rear directions, and the drive wheel bodies 12 and 42. Are provided so as to be able to travel separately.

  In the second embodiment, an upward receiving surface is formed on the front end side of the rear main body 41, and when the front main body 11 approaches the rear main body 11 on the rear end side of the front main body 11. A projecting body facing from above is provided with a gap on the receiving surface.

  That is, as shown in FIGS. 10, 12, and 13, on one side of the car wash machine body 10 in the left-right direction, for example, on the left side, on the front end side of the rear body 41, an upwardly-receiving surface 81 is formed by an upwardly opened step shape. Is formed. A C-shaped rail-shaped protrusion (bar) 82 is connected to the rear end side of the front body 11 and a receiving surface 83 is formed by the lower surface of the protrusion 82. Here, a plate 84 is integrated with the base end of the projecting body 82 by welding, and the plate 84 is connected to a rear surface of the front main body 11 by a connecting tool (bolt, nut, etc.) 85. The protrusion 82 is horizontal and protrudes backward. When the front main body 11 approaches the rear main body 41, the receiving surface 83 of the protrusion 82 is configured to face the receiving surface 81 from above with a gap H having a predetermined height.

  As shown in FIGS. 11, 14, and 15, between the front main body 11 and the rear main body 41 in the car wash machine main body 10, the rear main body 41 is disposed on the front main body 11 in the end position (traveling end position). Rear body stop means 90 is provided for detecting the approach and stopping the rear body 41 at the end position. The rear body stopping means 90 is disposed on one side of the car wash machine body 10 in the left-right direction, for example, on the right side, and an operating body 92 disposed on an upward surface 91 formed on the front end side of the rear body 41. The support body 95 is connected to the rear side from the rear end side of the front body 11 and the limit switch (detection body) 98 is provided on the support body 95.

  Here, the upward surface 91 is formed on the front end side of the rear main body 41 by a step shape that is open upward, and the operation body 92 is formed of a long hole 93 in the length direction and a connecting tool (bolt, nut, etc.) 94 to have a length. It is fixed on the upward surface 91 so that the position can be adjusted in the direction. The upper surface of the operation body 92 is formed as an introduction surface 92a whose free end (front end) is inclined downward, and a horizontal operation surface 92b is formed continuously to the introduction surface 92a.

  The support body 95 has a gate-shaped rail shape, and a base plate 96 is integrated with a plate 96 by welding, and the connecting member (bolt / nut) is brought into contact with the rear surface of the front body 11. Etc.) By connecting with 97, the support body 95 is projected in the horizontal direction and rearward. The limit switch 98 is provided in the support body 95 while being covered by the support body 95, and a detection portion 98 a is projected below the support body 95. The limit switch 98 is configured such that, when the rear main body 41 approaches the front main body 11, the detecting section 98a abuts on the operation surface 92b from the introduction surface 92a.

Hereinafter, the operation in the second embodiment will be described with reference to part of FIGS.
As shown in FIG. 9 (j), after the front main body 11 moves forward, it is confirmed that the front main body 11 has reached the end position (running end position) by the operation of the front main body EP detection sensor 37 ( Step-27), the forward command of the front main body 11 output to the traveling control unit is turned off, that is, a stop command is output (Step-28), and as shown in FIG. The front main body 11 is stopped in the state of being positioned at the position. At this time, the rear main body 41 continues to advance while the drying of the vehicle 1 by the drying nozzles 56 and 57 is executed.

  Subsequently, when it is confirmed by the operation of the rear main body stopping means 90 that the rear main body 41 has reached the end position (travel end position) (step -29), the forward command of the rear main body 41 output to the travel control unit is turned off. That is, a stop command is output (step-30), and a drive stop command for the drying nozzles 56 and 57 and the blower device 58 is output to the drying control unit (step-31).

  That is, when the rear main body 41 that has continued to move forward approaches the stopped front main body 11, first, as shown by the phantom line in FIG. 15, the introduction surface 92 a enters below the detection portion 98 a in the limit switch 98, Then, as shown by the solid lines in FIG. 14 and FIG. 15, the operation surface 92b abuts against the detection unit 98a to detect and move the detection unit 98a. As a result, it is confirmed that the rear body 41 has reached the end position (running end position), and the forward command for the rear body 41 is turned off, that is, a stop command is output, as shown in FIG. In addition, both the front main body 11 and the rear main body 41 are stopped at the end positions, and the driving of the nozzles 56 and 57 and the blower device 58 is stopped.

  After the stop command is output, the rear main body 41 is moved forward by inertial force. In this case, the detection unit 98a slides on the operation surface 92b, and the detection motion of the detection unit 98a is maintained. Then, the stopper body 66 can stop before contacting the front body 11.

  Further, when the front main body 11 and the rear main body 41 are stopped at the home position (travel start position) and the front main body 11 is approaching the rear main body 41, as indicated by phantom lines in FIGS. Furthermore, the protrusion 82 on the front body 11 side faces the receiving surface 81 on the rear body 41 side from above with a gap H. In such a state, the rear main body 41 is provided with the blower device 58 and the like of the drying means 55 at the upper part and the center of gravity is at the upper part. Therefore, when the rear main body 41 stopped at the home position is advanced by the inertial force. When the rear main body 41 that has been moved backward is stopped at the home position, it is tilted backward due to the inertial force.

  However, in these cases, when the rear main body 41 is slightly inclined rearward from the state of the phantom line in FIG. 13, as shown by the solid line in FIG. As a result, the gap H is absorbed, whereby the receiving surface 81 comes into contact with the receiving surface 83 of the projecting body 82 from below, and the rear body 41 is supported by the front body 11. Further collapse of the main body 41 can be prevented. At this time, when the falling force is large, the idle roller 48 comes into contact with and supports the left and right inclined surfaces 3a of the rail 3 from above.

  As described above, the rear main body 41 is light and inexpensive by adding a simple structure in which the front body 11 is provided with the protruding body 82 facing the upper surface with a gap H on the receiving surface 81 formed on the rear main body 41. While maintaining the reduction, the receiving surface 81 can be prevented from falling by the support action by contacting the protrusion 82 from below.

  When the rear main body 41 stopped at the end position is moved backward, it is tilted forward by an inertial force, or when the rear main body 41 that has advanced is stopped at the end position, it is tilted forward by an inertial force. However, in these cases, the rear main body 41 is located close to the front main body 11, so that it is received by the front main body 11 in the worst case.

In the first and second embodiments described above, the set separation distance (maximum separation distance) L is arbitrarily set, and there is no problem even if it is somewhat uneven for each car wash.
In the first embodiment described above, the rear main body 41 shows a form in which the idler roller (auxiliary wheel body) 48 is provided at a position opposite to the driven wheel body 43 with the driving wheel body 42 in the middle. However, this may be a form in which an auxiliary wheel body is additionally provided outside (frontward) the driven wheel body 43. Moreover, you may provide an auxiliary | assistant ring body in the front part main body 11 according to a design change.

  In the first and second embodiments described above, the auxiliary wheel body is formed of a pair of left and right idler rollers 48, which, like the drive wheel body 42 and the driven wheel body 43, form a V-groove. It may be a supplementary wheel body.

  In the above-described first and second embodiments, the form in which the scrapers 49 and 50 are provided at the outer positions of the driven wheel body 43 and the idler roller (auxiliary wheel body) 48 of the rear body 41 is shown. This may be a format provided in only one or a format in which both are omitted. Moreover, you may provide a scraper also in the front main body 11 side as needed.

  In the second embodiment described above, the receiving surface 81 is formed on the left side of the car wash machine body 10 and the projecting body 82 is provided, and the rear body stop means 90 is provided on the right side. Alternatively, the receiving surface 81 may be formed on both the left and right sides of the car wash machine main body 10, and the protruding body 82 may be provided.

In the second embodiment described above, the gap H is arbitrarily set.
In the first and second embodiments described above, the car wash machine body 10 (the front main body 11 and the rear main body 41) is moved so as to move relative to the vehicle 1 to wash the vehicle 1. However, this may be a type in which the front body 11 and the rear body 41 are moved and the vehicle 1 is moved by using a roller conveyor (vehicle moving means) so as to move relative to each other. .
