Description

  The present invention relates to a car wash machine that is installed, for example, in a gas station and used for car washing.

  Conventionally, the following configuration is provided as this type of car wash machine. That is, an upper surface drying nozzle (moving body) that moves up and down along the upper surface of the vehicle body, a single ring-shaped detection body having portions positioned at least below, in front and behind the upper surface drying nozzle, and the ring-shaped detection A support means for supporting the body on the upper surface drying nozzle so that the body moves up and down and swings back and forth with respect to the upper surface drying nozzle by contact with the vehicle body, a spring for urging the detection body to a neutral position, and the ring shape The switch is constituted by a switch that is actuated by vertical movement and back-and-forth movement of the detection body. The support means includes a movable plate fixed to the upper end portion of the ring-shaped detector and a shaft fixed to the movable body. This shaft is fitted in a vertically elongated hole formed in the movable plate, and supports the movable plate so that it can slide up and down and swing back and forth.

According to this conventional configuration, when the drying operation is performed, the upper surface drying nozzle is lowered without stopping due to a failure of a stop device or the like, and the ring-shaped detector contacts the roof of the automobile, the movable plate is moved via the ring-shaped detector. By moving upward, the switch is operated to stop the traveling of the portal traveling frame, and the collision between the upper surface drying nozzle and the automobile can be prevented. When the ring-shaped detector comes into contact with the rear glass of the automobile, the movable plate swings forward through the ring-shaped detector, and the detection piece is separated from the switch. The traveling of the frame can be stopped to prevent a collision between the upper surface drying nozzle and the automobile (see, for example, Patent Document 1).
JP-A-2-169351 (page 1-3, FIG. 3)

  However, according to the above-described conventional configuration, the lower part of the ring-shaped detector blocks a part of the air blowing port in the upper surface drying nozzle, which adversely affects the intended drying. Further, the structure becomes complicated by using a dedicated spring for biasing the detection body to the neutral position. Furthermore, the spring is weak against water (moisture), and when it is used in a car wash machine used by spraying a large amount of water, it has an unsuitable configuration, such as frequent maintenance and inspection. In addition, since the spring is a type in which the upper surface drying nozzle side and the movable plate are directly connected, the expansion and contraction operation and the tilting operation are performed in accordance with the vertical sliding and back-and-forth swing of the movable plate. A space for allowing these operations must be secured in the vicinity of, which hinders downsizing.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a car wash machine that can provide a detection body without blocking the outlet of the top nozzle, and can place the detection body in a neutral position without using a spring. It is what.

  In order to achieve the above-described object, the car wash machine according to claim 1 of the present invention cleans the vehicle to be cleaned by the cleaning means while relatively moving the vehicle to be cleaned and the car wash machine main body in the front-rear direction. A car wash machine that dries a vehicle to be cleaned by a drying means, and has a top nozzle that can be raised and lowered as the drying means, and a bracket is provided on the upper surface side of the top nozzle. A movable body that can be moved up and down is provided, and a pair of detector bodies that extend from one end and the other end of the hydraulic body to the vicinity of the ejection port of the top nozzle are connected to the hydraulic body. A pair of front and rear inclined surfaces which are spaced apart from each other at the portion facing the ejection port and are separated from each other toward the upper side of the working body are detected so that the detection unit is positioned between both inclined surfaces. It is obtained by characterized by providing a stage.

  Therefore, according to the first aspect of the invention, the intended drying operation can be performed while moving the top nozzle up and down along the shape of the upper surface of the vehicle to be cleaned. At that time, the air blown from the outlet of the top nozzle is blown through the separated portion between the two detection bodies, so that the lower part of both detection bodies does not block the outlet of the top nozzle. At this time, the operating body or the like is automatically and reliably lowered by the dead weight of the operating body or both detecting bodies, thereby positioning the detection unit between the lower portions of the both inclined surfaces, thereby neutralizing the detecting means. It can be a state.

  When the top nozzle descends without stopping at a predetermined level due to a failure of other equipment during the drying operation of the horizontal upper surface of the vehicle to be cleaned, both detectors come into contact with the horizontal upper surface prior to the top nozzle. As a result, a lifting force is applied to both detection bodies, thereby raising the operating body via both detection bodies. As the operating body rises, the two inclined surfaces lift the detection unit, thereby enabling the detection means to be in an operating state, and stopping the car wash machine main body by controlling through the detection means and the top. The nozzle can be raised to prevent a collision between the top nozzle and the vehicle to be cleaned. At that time, the operating body is raised smoothly while being guided to the bracket side, and the detection unit is lifted with a reduced frictional resistance while moving on the inclined surface on one side. When the top nozzle is raised and the action of the lifting force on the detection body is eliminated, the operation body and the like can be automatically lowered by the dead weight of the operation body and the detection body to return to the neutral state.

  In addition, if the top nozzle descends without stopping at a predetermined level due to a failure of other equipment during the drying operation of the inclined upper surface of the vehicle to be cleaned, one detector contacts the inclined upper surface prior to the top nozzle. Thus, a swinging force is applied to one of the detection bodies, and thus the operating body is swung back and forth via one of the detection bodies. As the operating body swings, any one of the inclined surfaces lifts the detection unit, so that the detection means can be in an operating state, and control of the detection means stops the traveling of the car wash machine main body. In addition, the top nozzle can be raised to prevent the top nozzle and the vehicle to be cleaned from colliding. At this time, the swinging of the operating body is smoothly performed while being supported and guided to the bracket side, and the detection unit is lifted while moving on any one of the inclined surfaces while reducing the frictional resistance. When the top nozzle is raised and the action of the swinging force on the detection body is eliminated, the operating body or the like can be automatically reversely swung back to the neutral state by the dead weight of the operating body or both detection bodies.

  According to the first aspect of the present invention, the desired drying operation can be suitably performed without waste while moving the top nozzle up and down along the shape of the upper surface of the vehicle to be cleaned. At that time, the wind blown from the outlet of the top nozzle is blown through the separated part between the two detection bodies, so that the lower part of both detection bodies does not block the outlet of the top nozzle, Therefore, the desired drying can always be suitably performed in a uniform state on the entire surface. At this time, the operating body or the like is automatically and reliably lowered by the dead weight of the operating body or the two detecting bodies, and thereby the detecting means can be positioned between the lower portions of the both inclined surfaces to make the detecting means neutral. .

  When the top nozzle descends without stopping at a predetermined level due to a failure of other equipment during the drying operation of the horizontal upper surface of the vehicle to be cleaned, both detectors come into contact with the horizontal upper surface prior to the top nozzle. As a result, a rising force is applied to both detection bodies, so that the operating body can be raised via both detection bodies. As the operating body rises, both inclined surfaces lift the detection unit, thereby enabling the detection means to be in an activated state, and stopping the car wash machine main body by control via the detection means. The top nozzle can be raised to prevent a collision between the top nozzle and the vehicle to be cleaned. At this time, the operating body can be raised smoothly while being guided to the bracket side, and the detection unit can be lifted with reduced frictional resistance while moving on the inclined surface on one side.

  In addition, one detection body comes into contact with the inclined upper surface prior to the top nozzle, and a swinging force is applied to one detection body, so that the operating body can be moved forward or backward through the one detection body. Can rock. As the operating body swings, one of the inclined surfaces lifts the detection unit, thereby enabling the detection means to be in an activated state, and stopping the car wash machine main body by control via the detection means. In addition, the top nozzle can be raised to prevent a collision between the top nozzle and the vehicle to be cleaned. At this time, the operating body can be smoothly swung while being supported and guided to the bracket side, and the detection unit can be lifted with reduced frictional resistance while moving on any inclined surface. it can.

  When the operating body ascends as described above or when the operating body swings back and forth, if the top nozzle rises and the action of the rising force or swinging force on the detection body is eliminated, The operating body or the like can be automatically and reliably lowered or reversely oscillated, thereby returning to the neutral state.

  In this way, by automatically raising or swinging the operating body back and forth by the contact pressure, it is possible to bring the detection means into an operating state while lifting the detection unit using a common inclined surface, and to detect the operating body and both detections. By automatically lowering or reversely swinging the operating body according to the weight of the body, the detecting means can be placed in the reverse operating state while the detecting portion is automatically lowered. Such an up-and-down and swinging configuration and a cam configuration using an inclined surface can be made resistant to water (moisture), and even if it is used in a car wash machine that sprays a large amount of water, maintenance inspection Therefore, it is possible to make a suitable configuration such as not having to be frequently performed, and it is possible to configure simply and compactly.

Further, stopper bodies 55 are provided in the middle part of the main body 51a on both side portions in the left-right direction B so as to be adjustable in position via bolts 56 and the like. A slide receiving body 57 for guiding the operation of an operating body (described later) is provided at an intermediate portion of the main body 51a of the bracket 51 via a bolt 58 or the like.

  An operating body 61 that can swing back and forth and move up and down with respect to the bracket 51 is provided.

It is connected via a connector (bolt / nut etc.) 66. Both detectors 64 and 65 are covered with a protective tube so as not to damage the vehicle body when touched. Cylindrical covers 67 are provided at the free ends thereof, that is, at the free ends of both lower circular arc portions 64c and 65c, respectively. In addition, a lacking portion 68 is formed between the cylinder covers 67 that are separated from each other in the front-rear direction so as to face the ejection port 21 a of the top nozzle 21.

  The operating body 61 is formed with a pair of front and rear inclined surfaces that are separated from each other toward the top. That is, a pair of front and rear guide members 71 and 72 are connected to the lower outer surface of the operating body 61 via connecting tools (bolts and nuts) 73 and 74. Here, the guide members 71 and 72 are arranged and connected in an inverted C shape, and thus a pair of front and rear inclined surfaces 71a, which are separated from each other upward by a pair of upward faces that are inverted C shape. 72a is formed.

  At that time, the inclination angle θa of the inclined surface 71a of the guide member 71 located on the side close to the operating shaft (described later) of the arm is small (loose), and is positioned on the side (opposite side) far from the operating shaft. The inclination angle θb of the inclined surface 72a of the guide member 72 is large (tight), that is, θa <θb. The inclination angles θa and θb are set to angles that do not interfere with the operation locus of the roller (described later) on the locus of the operating body 61. Note that a stopper body 75 (see FIG. 9) capable of contacting the stopper body 55 is provided on both guide members 71 and 72 side.

  On the top nozzle 21 side, a limit switch (an example of detection means) 81 is provided so that a roller (an example of a detection unit) 85 is positioned between the inclined surfaces 71a and 72a. That is, the switch bracket 80 is provided at a position near the front portion on the top surface of the top nozzle 21, and the switch body 82 is fixed to the switch bracket 80. An arm 84 is attached to an operating shaft 83 protruding from the switch body 82, and the roller 85 positioned between the inclined surfaces 71a and 72a is rotatably provided at the free end of the arm 84. An example of the limit switch 81 is configured by the above 82 to 85 and the like. Near the switch bracket 80, a terminal block 86 connected to the switch body 82 via a cord is provided.

  The bracket 51, the operating body 61, the limit switch 81, the terminal block 86, and the like can be stored in a box-shaped cover body 88. Here, the cover body 88 is attached to the side connection portion 51c of the bracket 51 via a connection tool (bolt, nut, etc.) 89. A through hole 88A that allows passage of the portions 64a and 65a is formed as an elongated hole in the vertical direction.

  As shown in FIGS. 2 and 3, an operation panel 91 is provided on the front surface of the right vertical frame portion in the car wash machine body 10, and a control device 92 that controls the operation of each unit is provided on the back surface side of the operation panel 91. Is provided. A vehicle height sensor (not shown) is provided in the upper part of the car wash machine body 10.

The operation in the above embodiment will be described below.
When performing the car wash, first, the driver or the operator operates the operation panel 91 in a state where the vehicle 5 to be cleaned is stopped, so that one desired car wash course (cleaning condition) is set. By turning on the car wash start switch in this state, the brush 18, 19, 20 spreads by rotation while the car wash machine body 10 reciprocates, and the water through the wash water nozzles 12, 14 is moved. Supply of (washing water), supply of diluted detergent through detergent nozzles 13, 16, supply of diluted water repellent coating agent through water repellent coating agent nozzle 15, dilution through wax nozzle 17 The desired basic cleaning process and drying process for the vehicle 5 to be cleaned can be performed by appropriately combining the supply of wax and the blowing (blowing) of wind from the nozzles 21 and 22. It will be.

When performing such a car wash process, the vehicle height, the vehicle length, and the like are detected by a vehicle height sensor and appropriate detection means, and the above-described operating units are preferably operated via the control device 92 and the like.
In this way, the desired car wash can be performed. At that time, the top nozzle 21 is moved up and down by driving the forward / reverse drive unit 33 forward and backward by the control of the control device 92 based on the detection of the vehicle height sensor. By rotating the rotating body 37 forward and backward through the winding transmission device 34 and the lifting drive shaft 32, the left and right pair of lifting bodies 41 are moved up and down synchronously while being guided by the guide body 38. The rotation shaft 43 can be used. Further, the direction (angle) of the top nozzle 21 can be changed by extending the cylinder device 48 under the control of the control device 92 and rotating the rotary shaft 43 against the springs 47 with respect to the left and right lifting bodies 41. .

  As a result, as shown in FIGS. 10 and 14, a suitable drying operation without waste can be performed while moving the top nozzle 21 along the shape of the upper surface of the vehicle 5 to be cleaned. The top nozzle 21 is directed downward for 5a and the like, and the drying operation can be performed with the top nozzle 21 changed to a suitable orientation (angle) for the rear glass portion 5b and the like. Further, the wind blown from the ejection port 21a of the top nozzle 21 is blown through the separated portions of the detection bodies 64 and 65, that is, through the lacking portion 68, so that the lower portions of the detection bodies 64 and 65 are placed on the top nozzle 21. Therefore, the desired drying can always be suitably performed uniformly on the entire surface.

  At this time, the operating body 61 and the detecting bodies 64 and 65 are automatically and surely lowered by the dead weight of the operating body 61 and the detection bodies 64 and 65, and thereby, between the lower portions of the inclined surfaces 71 a and 72 a of the both guide members 71 and 72. The roller 85 is positioned to make the arm 84 horizontal, so that the limit switch 81 is in an on (detected) neutral state.

In addition, by setting the neutral position to ON, it is possible to easily grasp the state of the limit switch (such as the disconnection of the cable to the control device) before the car wash starts.
When the top nozzle 21 descends without stopping at a predetermined level due to a failure of the photoelectric sensor 49 or the like during the drying operation of the roof portion 5a or the like as described above, both the head nozzles 21 precede the top nozzle 21 as shown in FIG. The lower circular arc portions 64c and 65c of the detection bodies 64 and 65 come into contact with the roof portion 5a of the vehicle 5 to be cleaned, and a rising force is applied to the detection bodies 64 and 65. The operating body 61 is raised through 65. As the operating body 61 is raised, the inclined surfaces 71a and 72a of both guide members 71 and 72 lift the roller 85, thereby swinging the arm 84 and rotating the operating shaft 83, thereby limiting the limit. The switch 81 is turned off (not detected). Then, the traveling of the car wash machine main body 10 is stopped and the top nozzle is raised by the control of the control device 92 via the terminal block 86, so that the collision between the top nozzle 21 and the roof portion 5a can be prevented.

  The raising of the operating body 61 is smoothly performed while being guided by the swing support shaft 54 within the allowable range of the long hole 62 and by being slidably guided by the slide receiving body 57, and the roller 85 is lifted up. The frictional resistance is reduced while the roller 85 is idled on the inclined surface 71a on the limit switch 81 side. When the top nozzle 21 is raised and the action of the lifting force on the detection bodies 64 and 65 is eliminated, the operation body 61 and the like are automatically and surely lowered by the dead weight of the operation body 61 and the detection bodies 64 and 65. Thus, the neutral state shown in FIG. 10 can be restored.

  When the top nozzle 21 descends without stopping at a predetermined level due to a failure of the photoelectric sensor 49 or the like during the drying operation of the rear glass portion 5b or the like as described above, the top nozzle 21 precedes the top nozzle 21 as shown in FIG. Thus, the lower arc portion 65c of the rear detection body 65 comes into contact with the rear glass portion 5b of the vehicle 5 to be cleaned, and a forward swinging force is applied to the rear detection body 65. The operating body 61 is swung forward around the swing support shaft body 54 via 65.

  As the operating body 61 swings forward, the inclined surface 72a of the guide member 72 lifts the roller 85, thereby swinging the arm 84 and rotating the operating shaft 83, whereby the limit switch 81 is It becomes an off (non-detection) state. Then, the traveling of the car wash machine main body 10 is stopped and the top nozzle is raised by the control of the control device 92 via the terminal block 86, so that the collision between the top nozzle 21 and the rear glass portion 5b can be prevented.

  The forward swing of the operating body 61 is smoothly performed while being guided by the swing support shaft body 54 through the long hole 62 and by being slidably guided by the slide receiving body 57, and the roller 85 is lifted up. The frictional resistance is reduced while the roller 85 is idled on the inclined surface 72a opposite to the limit switch 81. When the top nozzle 21 is raised and the action of the swinging force on the detecting bodies 64 and 65 is eliminated, the operating body 61 and the detecting bodies 64 and 65 are automatically and reliably reversely rocked by their own weight. Thus, the neutral state shown in FIG. 10 can be restored.

  Further, when the top nozzle 21 descends without stopping at a predetermined level due to a failure of the photoelectric sensor 49 or the like during the drying operation of the windshield portion 5c or the like as described above, the top nozzle 21 precedes the top nozzle 21 as shown in FIG. As a result, the lower arc portion 64c of the front detection body 64 comes into contact with the windshield portion 5c of the vehicle 5 to be cleaned, and a backward swinging force is applied to the front detection body 64. The operating body 61 is swung back and forth around the swing support shaft body 54 via the detection body 64.

  As the operating body 61 swings backward, the inclined surface 71a of the guide member 71 lifts the roller 85, thereby swinging the arm 84 and rotating the operating shaft 83, whereby the limit switch 81 is It is turned off (not detected). Then, the traveling of the car wash machine main body 10 is stopped and the top nozzle is raised by the control of the control device 92 via the terminal block 86, so that the collision between the top nozzle 21 and the windshield portion 5c can be prevented.

  The backward swing of the operating body 61 is smoothly performed while being guided by the swing support shaft body 54 through the elongated hole 62 and by being slidably guided by the slide receiving body 57, and the roller 85 is lifted up. The frictional resistance is reduced while the roller 85 is idled on the inclined surface 71a on the limit switch 81 side. When the top nozzle 21 is raised and the action of the swinging force on the detecting bodies 64 and 65 is eliminated, the operating body 61 and the detecting bodies 64 and 65 are automatically and reliably reversely rocked by their own weight. Thus, the neutral state shown in FIG. 10 can be restored.

  The front-rear swing of the operating body 61 as described above is regulated by the front and rear stopper bodies 75 coming into contact with the stopper body 55, thereby restricting the maximum amount of rotation. Further, when the operating body 61 swings back and forth, the operating body 61 may be accompanied by an upward movement. When the tilt angle θa of the front-side inclined surface 71a is made smaller than the inclination angle θb of the rear-side inclined surface 72a, the operating body 61 is raised through the detecting bodies 64 and 65 as described above. In addition, it is possible to smoothly move the roller 85 on the inclined surface 71a on the limit switch 81 side while lifting the roller 85.

  As described above, the limit switch 81 is turned off (not detected) while the roller 85 is lifted using the common inclined surfaces 71a and 72a by automatically raising or swinging the operating body 61 by contact pressure. The limit switch 81 is turned on (detected) while the roller 85 is automatically lowered by automatically lowering or reversely swinging the actuator 61 by the weight of the actuator 61 and the detectors 64 and 65. It can be a state. Such a configuration of raising and lowering and swinging and a cam configuration using the inclined surfaces 71a and 72a are resistant to water (moisture), and even if they are adopted in a car wash machine that uses a large amount of water sprayed. Thus, the maintenance and inspection need not be frequently performed, and the configuration is suitable, and the configuration can be simple and compact.
