In this car washing device, a portal frame 101 formed so as to straddle the automobile 100 as shown in FIGS. 14 and 15 runs on wheels 102 provided at a lower portion thereof, and moves in a front-rear direction of the automobile 100. And relative movement is possible.

The portal frame 101 is provided with a pair of left and right nozzles 103 which move up and down the H region or h region along the left and right inner sides, respectively. A nozzle 106 that moves left and right in the W region or the w region at the bottom is provided. Upper nozzle 106

In a conventional car washing apparatus, a traveling device for vertically moving or horizontally moving nozzles 103 and 106 mainly used for liquid is provided with an endless space between a pair of sprockets 115 as schematically shown in FIG. A chain 116 (or a toothed belt) is stretched over, and a nozzle base 118 serving as a base for mounting the nozzles 103 and 106 is provided at one position of the chain 116.

The nozzle base 118 has a nozzle 10
A hose 119 for supplying a predetermined liquid is connected to 3, 106.

[0007]

SUMMARY OF THE INVENTION Nozzles 103 and 106
In the traveling device, the pair of sprockets 115 need to be attached in a state where they are separated from each other by a considerable distance (a distance exceeding the width and height of the automobile 100). Therefore, a frame that supports the sprockets 115 with strength and precision is required.

Therefore, in the conventional traveling device, as shown in FIG. 17, the sprocket 115 and its driving motor and the like are directly attached to the components of the portal frame 101 (that is, the traveling device is a portal type). (It was integrally assembled to the frame 101), which made it difficult to reduce the size and simplify the structure of the traveling device. In addition, since it is necessary to adjust the tension in the endless chain 116 so as to always maintain the tension in a predetermined range, it is necessary to perform periodic maintenance in a relatively short period of time. for that reason,
There was also one aspect that maintenance was troublesome and maintenance costs could not be reduced.

Further, since the hose 119 connected to the nozzle base 118 is always swung about the same position as a fulcrum, local deterioration or breakage of the material is likely to occur at this oscillating fulcrum part. There was a problem. The present invention
It has been made in view of the above circumstances, and it is possible to reduce the size and simplify the structure as a nozzle traveling device, and also to simplify maintenance and reduce costs by reducing the frequency of maintenance. An object of the present invention is to provide a nozzle traveling device of a car washing device capable of improving the durability of a hose or the like.

[0010]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, according to the present invention, there is provided a car wash apparatus having a portal frame that moves relative to the vehicle over a car, and is provided with a nozzle that moves up and down on the left and right sides and a nozzle that moves left and right on the upper side. A nozzle traveling device that can be used to drive one or both nozzles, a sprocket that can be rotated forward and backward by a motor, and a halfway portion in the longitudinal direction is wound around the sprocket, and one end is in a nozzle operating direction. , A nozzle base provided at an end of the chain on the advance / retreat side, and a fluid supply hose connected to the nozzle base.

With such a configuration, when the sprocket is driven and rotated in one direction (for example, this direction is defined as the normal rotation direction), the chain is in a state where the links are pressed and held via the connecting pins. Alternatively, the link is in a pressing state in which the links directly contact each other. Therefore, the side of the chain where the nozzle base is provided advances along the nozzle operation direction.

At this time, it is preferable to provide a chain guide on the side of the chain on which the nozzle base is provided so as not to bend in directions other than the nozzle operation direction. With this configuration, the driving force of the pressing force transmitted between the links of the chain is not only the load of the nozzle base and the nozzle attached thereto, the weight of the chain, but also the ejection reaction (fluid) of the fluid added to the nozzle. If water is water, its injection pressure can reach as high as 100 kg / cm ² , and its reaction will also be quite large). Therefore, a sufficient driving force for smoothly operating the nozzle base, the nozzle, and the like is transmitted without bending each link.

On the other hand, if the sprocket is rotated in the opposite direction (that is, in the reverse direction), the chain receives a tensile force and the side on which the nozzle base is provided has sufficient driving force along the nozzle operation direction. With it comes to retreat. Thus, the nozzle base can be reciprocated within a predetermined stroke by alternately rotating the sprocket in the normal rotation direction and the reverse rotation direction for a predetermined time.

In such a configuration, the chain does not need to be endless unlike the conventional one, and the sprocket only needs to be provided on one side in the chain moving direction. Therefore, the overall traveling apparatus can be reduced in size and simplified in structure. Becomes possible. In addition, the nozzle includes not only a case where the nozzle is shared with water, a detergent, or a mixture thereof, but also a case where the nozzle is individually provided only for each of these liquids or only for wax,
In some cases, it may be used to blow air during drying after car washing.

In the chain, a U-turn portion is provided at a portion opposite to the side where the nozzle base portion is provided from a portion wound around the sprocket, and the end of the U-turn is fixed to an appropriate position near the sprocket. It is possible (claim 3). In this way, when the chain is operated to move the nozzle base closer to the sprocket, the chain slack generated on the opposite side of the sprocket can be stored in a small space without causing tangling or the like in the chain. Can be. Therefore, this also leads to downsizing of the traveling device.

[0016] The fluid supply hose has the chain held along the sprocket and the U-turn portion from the nozzle base through the sprocket and the U-turn toward the sprocket, and the hose end opposite to the side connected to the nozzle base is connected to the chain. The sprocket can be fixed to an appropriate position, and the fluid can be supplied through a member that is a counterpart of the fixing (claim 4).

According to this configuration, the fluid supply hose can be accommodated in a space-saving manner like the chain, without causing the fluid supply hose itself or the chain between the fluid supply hose and the chain. In addition, since the fluid supply hose is held in such a manner that its longitudinal direction is adjacent to the chain, the fluid supply hose is bent in the same manner in parallel with the chain at a portion where the chain is wound around the sprocket, and has a substantially full length. Will be repeated with equal frequency. Therefore, the fluid supply hose has an advantage that local material deterioration, breakage, and the like hardly occur, and durability is improved.

The fluid passing through the fluid supply hose can be appropriately changed, similarly to the fluid ejected from the nozzle. In addition, various position detectors, solenoid valves, and the like can be provided on the nozzle base and the nozzle. In such a case, it is necessary to connect a power supply line, a signal line, and the like to the nozzle base. . Therefore, for such power supply lines and signal lines,
Wiring can be performed in a similar route as the fluid supply hose (ie, to hold along the chain).

As the sprocket and the chain, two sets of sprockets and a chain which are parallel to each other at a predetermined interval may be juxtaposed, and a storage portion for the fluid supply hose may be provided between the juxtapositions. It goes without saying that the drive transmission force of the chain is increased in this way. Further, since the fluid supply hose can be held adjacent to the chain in a space-saving manner, it is useful for downsizing and simplifying the structure of the traveling device.

The nozzle traveling device according to any one of claims 1 to 5 can be unitized because its structure is simplified, and in this case (claim 6), it is easy to assemble and maintain. Becomes possible. A sprocket 3 supported by the main body frame and capable of rotating forward and reverse by driving the motor 2, and a halfway portion in the longitudinal direction is wound around the sprocket 3 so that one end 4 a can advance and retreat along the nozzle operation direction. A chain 4, a nozzle base 5 provided at an end 4a of the chain 4 at the reciprocating side, and fluid supply hoses 12 and 13 connected to the nozzle base 5. A chain guide 40 for guiding the movement of the chain can be provided.

In this case (claim 7), the structure for driving the nozzle to travel can be configured independently.

[0022]

Embodiments of the present invention will be described below with reference to the drawings. 2 and 3 show an overall view of the nozzle traveling device 1 according to the present invention, and FIG. 1 schematically shows an operation state of the nozzle traveling device 1. The nozzle traveling device 1 of the present embodiment is configured to drive the nozzle 103 that moves up and down along each of the left and right inner sides of the portal frame 101 in the car washing device illustrated in FIGS. 14 and 15. .

The nozzle traveling device 1 includes a sprocket 3 rotatable forward and backward by a motor 2, a chain 4 wound around the sprocket 3, and a nozzle base 5 provided at one end 4a of the chain 4. And The nozzle base 5 is provided with two nozzles 8 and 9, and one end of each of fluid supply hoses 12 and 13 (see FIG. 3) for supplying water or the like to each of the nozzles 8 and 9 is connected.

The end of the hose opposite to the side connected to the nozzle base 5 is fixed to the same member as the fixed end 4b of the chain 4 (a joint piece 35 described later with reference to FIG. 6).
Primary hoses 17 and 18 connected to a fluid supply source (not shown) are connected to the joint piece 35.

Therefore, when the sprocket 3 is alternately rotated in the forward and reverse directions in the nozzle traveling device 1, the nozzles 8, 9 can be moved up and down together with the nozzle base 5. At this time, the fixed end portion 4 is smaller than the sprocket 3.
The U-turn portion 15 moves up and down by increasing or decreasing the length unwound toward the b side. Fluid supply hose 1
2 and 13 follow the movement of the chain 4 and perform exactly the same vertical movement and bending operation.

Therefore, regardless of the height of the nozzle base 5 and the vertical movement of the nozzle base 5, a predetermined fluid can be ejected from the nozzle 8 or 9 as necessary. Can be. Such a nozzle traveling device 1 includes:
A drive housing 20 for accommodating the sprocket 3 and supporting its rotation, and a main body frame 21 connected to the drive housing 20 downward are unitized.

The operation of the chain 4 and the fluid supply hoses 12 and 13 are all accommodated and guided inside the drive housing 20 and the main body frame 21, and the main body frame 21 causes the nozzle base 5 to move up and down. It is being guided. In this nozzle traveling device 1, two chains 4 are used in parallel with each other as shown in FIGS. Accordingly, two sprockets corresponding to the respective chains 4 are naturally provided at predetermined intervals by the connecting shaft 22. The fluid supply hoses 12 and 13 are held in a form sandwiched between the two chains 4.

As shown in FIGS. 4 and 5, the drive housing 20 has a box body 25 and an insertion frame 26 fitted into the box body 25. The box body 25 has one
A recess 27 into which the sprocket 3 is fitted is formed along the inner wall of the set, and a hose passage 28 having an enlarged inner diameter is formed between the recess 27 and the recess 27. The recess 27 and the hose passage 28 are open downward from the box body 25.

The inner surface of the recess 27 in the circumferential direction is the chain 4
Rail surface 27 that prevents the sprocket 3 from coming off the sprocket 3
a. At the center of the recess 27, a mounting hole 31 for the motor 2 and the bearing 30 is formed. On the other hand, the insertion frame 26 is fitted between the concave portions 27 of the box body 25 and has two support arm portions 34 each of which holds a predetermined interval between the adjacent rail surfaces 27a. , The joint piece 3 projecting to the opposite side (lower side) of the support arm portion 34
5 is provided. The support arm 34 guides the sliding movement of the chain 4 at a portion of the recess 27 parallel to the rail surface 27a as a cooperative action therewith.

As shown in FIG. 6, the joint piece 35 of the insertion frame 26 has a connection port portion for the fluid supply hoses 12, 13 on the lower surface portion, and the above-described primary side hoses 17, 18 on the side surface portion.
And these are connected internally for each set. A chain connector 36 used to fix the end 4 b of the chain 4 is attached to another side surface of the joint piece 35.

As shown in FIG. 7, the main body frame 21 includes a chain guide 40, a chain cover 41 provided on the back side thereof, and a pair of side plates 4 connecting these at a predetermined interval.
2 and 2 are formed into a square pipe shape. Chain guide 40
Are provided in accordance with the mutual interval between the two chains 4.
The rail 43 is provided. The rails 43 have lateral U-shaped cross sections facing each other.
Guide the nozzle so that it does not bend in any direction other than the nozzle operation direction (upper and lower linear directions).

The chain cover 41 includes two chains 4.
Two chain rests 44 provided in accordance with the mutual spacing of
have. A chain 4 inserted into the rail 43 of the chain guide 40 and a chain pad 44 of the chain cover 41
The spacing between the chain and the chain 4 which is abutted on the inside thereof is kept substantially equal to the pitch circle diameter of the sprocket 3 by the side plate 42.

As the chain 4, as shown in FIGS. 8 and 9, a roller chain in which a roller 49 having a diameter larger than the links 47 and 48 is rotatably held with respect to the link connecting pin 46 is used. I have. The outer link 48 is provided with a mounting piece 50 that protrudes in a bent shape toward one side.
Therefore, as shown in FIG. 7, the two chains 4 are used so that the mounting pieces 50 are opposed to each other.
0 allows the hose receiving fitting 52 and the hose holding lid 53 to be attached.

It should be noted that the mounting piece 50 is connected to all the outer links 48.
The hose receiving fitting 52 and the hose holding lid 53 may be attached to all of the outer links 48, or every other or several outer links 4 may be provided.
8 and so on.
As shown in FIGS. 10 and 11, the nozzle base 5 includes:
A flow path 55 for guiding the fluid sent from the fluid supply hose 12 to the nozzle 9 and a flow path 56 for leading the fluid sent from the fluid supply hose 13 to the nozzle 8 are formed.

Since one nozzle 8 is fixed to the nozzle base 5, the fluid sent from the fluid supply hose 12 is jetted from the nozzle end as it is. However, the other nozzle 9 is provided with a cylinder body 58 so as to be able to expand and contract in the axial direction. Therefore, the fluid sent from the fluid supply hose 13 once flows into the cylinder body 58 to extend the nozzle 9 and fill the cylinder body 58 (after reaching a predetermined pressure). From the nozzle end.

The flow path 56 communicating with the nozzle 8 has:
A branch path 59 is connected in the middle thereof, and the branch path 59 is connected to a back pressure application port 60 for contracting the nozzle 9 in the cylinder body 58. for that reason,
When the fluid is sent to the fluid supply hose 13 so that the fluid is ejected from the nozzle 8 on the fixed side as described above, the back pressure application port of the cylinder body 58 is supplied from the fluid supply hose 13 through the flow path 56 and the branch path 59. Fluid is also supplied to 60. As a result, the nozzle 9 is forcibly and reliably returned from the extended state to the retracted state.

The switching between the use of the nozzles 8 and the nozzles 9 is performed by the operation of an electromagnetic valve (not shown) for switching whether or not to supply the fluid to the fluid supply hoses 12 and 13. The operation of the solenoid valve is controlled by the car wash device (Fig. 1).
4 and FIG. 15) is automatically or artificially switched according to the size of the vehicle 100 (for example, a difference in body width between a normal vehicle and a mini 4 vehicle).

In switching the operation of the solenoid valve,
A position detector or the like for detecting the distance from the automobile 100 can be attached to the nozzle base 5 or the like. In this case, in connecting a power supply line, a signal line, and the like to the nozzle base 5, wiring can be performed along the same route as the fluid supply hoses 12, 13 (that is, in a state of being held along the chain 4). .

As is clear from the above description, in the nozzle traveling device 1 according to the present invention, when the sprocket 3 is driven and rotated in one direction (normal rotation direction), the chain 4 is linked to the link 4
7 and 48 are in a pressing state via the connecting pin 46, and the side of the chain 4 where the nozzle base 5 is provided is pushed downward. At this time, since the chain 4 is guided by the chain guide 40,
The driving force of the pressing force transmitted between the links 47 and 48 is not only the total load of the nozzle base 5 and the nozzles 8 and 9 and the own weight of the chain 4 but also the jet reaction of the fluid added to the nozzles 8 and 9. Overcome the operating resistance of. Therefore, the nozzles 8 and 9 are advanced downward without bending the links 47 and 48.

On the other hand, if the sprocket 3 is rotated in the direction opposite to the above (reverse direction), the chain 4 naturally receives a strong pulling force, so that the nozzles 8 and 9 move upward. Thus, the nozzles 8 and 9 can be moved up and down within a predetermined stroke by alternately rotating the sprocket 3 in the normal rotation direction and the reverse rotation direction for a predetermined time.

When the nozzles 8 and 9 move upward,
In the chain 4, the slack increases on the opposite side of the sprocket 3, and the U-turn part 15 descends. 21.
The nozzle traveling device 1 supports the motor 4 and the sprocket 3 on a main body frame including a drive housing 20 and a main body frame 21 and a chain guide 40. Supportable,
The fluid supply hoses 12, 13 and the like can be attached, and are configured separately from the portal frame 101. Therefore, the nozzle traveling device 1 can be configured independently and incorporated in the portal frame 101, or can be used as a car washing device independently of the portal car washing device.

The present invention is not limited to the above embodiment. For example, the drive housing 20 (FIG. 4)
(See FIG. 5), the box body 25, the support arm portion 34, the chain guide 40, the chain cover 41, and the like in the main body frame 21 (see FIG. 7), such as a cushioning material such as resin or rubber for the contact portion with the chain 4. The friction resistance with the chain 4 can be reduced by sticking, coating, or forming by the cushioning material itself. in this case,
Since the cushioning material also has an effect of absorbing the collision of the chain 4 to some extent, there is an advantage that noise can be reduced and wear can be suppressed.

The combination of the chain 4 and the sprocket 3 may be only one set or three or more sets.
As the chain 4, various chains other than the roller chain can be used. Chain 4 for sprocket 3
Is not limited to a U-turn shape (180 °), and can be changed as appropriate according to the required push-pull torque or the like.

The mating member for fixing one end (4b side) of the chain 4 is not limited at all. Further, fixing the end 4b itself is not limited. In the chain 4, as shown in FIG. 12 and FIG. 13, the front and rear ends 48a of the out-of-width link 48 may be abutted against each other to increase the transmission force of the pressing force.

The chain guide 40 of the main body frame 21 (see FIG. 7) can be freely bent in the direction in which the chain 4 allows bending. That is, the nozzle operation direction may be not only a straight line but also a curved line, and the chain guide 40 restricts the movement of the nozzles 8 and 9 to a position other than a required operation path. The nozzles 8 and 9 are not only used in common for water, detergent, or a mixture thereof, but also provided separately for each of these liquids, or separately provided for wax. It is possible. Further, in some cases, air is blown out at the time of drying after car washing (the drying nozzle 1 shown in FIGS. 14 and 15).
07)).

The number and angle of the nozzles provided for the nozzle base 5, the nozzle shape, and the type thereof (such as a cylinder type) are not limited at all. Various sensors can be attached to the nozzle base 5, and the wiring for the sensors is connected to the chain 4 together with the fluid supply hoses 12 and 13.
Is held and guided. The end of the fluid supply hoses 12, 13 and the like opposite to the side where the nozzle base 5 is provided may not be attached to the joint piece 35. For example, the box body 25, the main body frame 21 or the like may be attached. The closer one is preferable because the chain 4 and the fluid supply hoses 12 and 13 can be shortened.

The nozzle traveling device 1 according to the present invention is different from the car washing device (see FIGS. 14 and 15) in that
It is, of course, possible to drive the nozzle 106 that moves left and right in the lower part of the upper part 1 via a vertically movable support frame 105. In this case, it is also possible to provide a mechanism for swinging the nozzle 106 in the nozzle base 5 according to the body shape of the automobile 100.

[0048]

As is apparent from the above description, according to the present invention, the sprocket can be rotated forward and backward by the motor, and the sprocket is wound around the middle part in the longitudinal direction. It has a chain whose side can be advanced and retracted along the nozzle operation direction, a nozzle base provided at an end of the chain on the advance and retreat side, and a fluid supply hose connected to the nozzle base. The nozzle base can be reciprocated within a predetermined stroke along the nozzle operation direction by alternately rotating in the rotation direction and the reverse direction alternately for a predetermined time.

At this time, if a chain guide is attached to the chain so that the side on which the nozzle base is provided does not bend in directions other than the nozzle operation direction (claim 2), when the chain is pushed out and advanced, The driving force of the pressing force transmitted between the links can be increased without bending the links. Therefore, it is possible to smoothly operate the nozzle base portion, the nozzle, and the like.

In such a chain bridging structure, the chain does not need to be endless, and the sprocket only needs to be provided on one side, so that the overall traveling apparatus can be reduced in size and simplified in structure. In Chen,
A U-turn portion is provided at a portion opposite to the side where the nozzle base is provided from a portion wound around the sprocket,
If the end of the U-turn is fixed to a proper position near the sprocket (Claim 3), the chain slack increases on the opposite side of the sprocket when the nozzle base is operated to approach the sprocket side. To
It can be stored in a small space without causing tangling or the like in the chain. Therefore, this also leads to downsizing of the traveling device.

If the fluid supply hose is held adjacent to the chain (claim 4), the fluid supply hose can be accommodated in a space-saving manner like the chain, and the fluid supply hose itself or the fluid supply hose and the chain can be connected. It can be stored without causing entanglement or the like. In addition, the fluid supply hose is bent in the same way in parallel with the chain at the portion where the chain is wound around the sprocket, and the entire length thereof is repeatedly bent at an equal frequency.
There is an advantage that local material deterioration, breakage, and the like hardly occur, and durability is improved.

Two sets of sprockets and chains parallel to each other are arranged at a predetermined interval, and a storage portion for the fluid supply hose can be provided between these juxtapositions. It goes without saying that the drive transmission force of the chain is increased in this way. Further, since the fluid supply hose can be held adjacent to the chain in a space-saving manner, it is useful for downsizing and simplifying the structure of the traveling device.

The nozzle traveling device according to any one of claims 1 to 5 can be unitized because its structure is simplified, and in this case (claim 6), assembling and maintenance are easy. Becomes possible. A sprocket 3 supported by the main body frame and capable of rotating forward and reverse by driving the motor 2, and a halfway portion in the longitudinal direction is wound around the sprocket 3 so that one end 4 a can advance and retreat along the nozzle operation direction. A chain 4, a nozzle base 5 provided at an end 4a of the chain 4 at the reciprocating side, and fluid supply hoses 12 and 13 connected to the nozzle base 5. It is possible to provide a chain guide 40 for guiding the movement of the nozzles, and in this case (claim 7), the structure for driving and driving the nozzles can be configured independently.
