Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called unit type car wash system in which a plurality of washing units are supplied with washing water or the like from one supply unit.

[0002]

2. Description of the Related Art In recent years, so-called coin-type car-washing stations for performing car washing using a car washing machine by self-service are increasing. Such coin-operated car wash areas include those equipped with a hand-held spray-type car wash unit and those equipped with an automatic car wash machine.

In a hand-held spray type car washing unit, an operation unit and a washing gun are arranged in a plurality of car washing booths, and washing water and the like are supplied to each washing gun via a pipe from a supply unit having a washing water tank and a water pump. It is possible. Some of the operation units include a car wash course selection unit, a fee receiving device, and the like.

[0004] On the other hand, there is a car wash where automatic car wash machines are arranged to provide a car wash service. In this case, the automatic car washer is equipped with a washing water tank, washing water heating device, etc.
Some include a car wash course selection unit, a charge receiving device, and the like, which are the same as those of the above-described hand-held type. In some cases, a plurality of automatic car washer machines are arranged in a car wash area to increase the turnover rate. At this time, a plurality of automatic car washing machines are individually provided with washing water tanks.

[0005]

In the case of the above-mentioned hand-held spray type car washing unit, the washing operation is performed by the user himself holding the washing gun and injecting washing water over the entire surface of the vehicle body. The high-pressure washing water bounces off the vehicle body, so that the user may be splashed or splashed from the next booth, which may make the user unpleasant.

[0006] Further, since the hand-held spray type car washing unit is a car washing operation performed by the user himself, skill is required to obtain a uniform and high quality finish, and depending on the skill of the user, after the washing operation by the car washing unit, In some cases, additional cleaning with a sponge or the like was required.

[0007] To each cleaning gun, cleaning water or the like is supplied from a high-pressure pump provided on the water supply unit side. When a large number of washing guns are arranged, it is required that a washing gun provided in a car washing booth far from the water supply unit has a sufficient injection pressure for washing the car. For this reason,
The supply line from the water supply unit to the cleaning gun had to use high-pressure piping. Further, since the high-pressure pipe is of a small diameter in terms of economy, the pressure loss becomes remarkable as the supply distance becomes longer, and it is necessary to use a powerful high-pressure pump taking this into account. As a result, the equipment cost and the running cost are increased.

Further, if the supply pressure is excessively increased in order to increase the cleaning performance, the jet reaction force of the cleaning gun is increased, and the workability is deteriorated, so that there is a limit to increasing the pressure.

The hand-held spray-type car washing unit has the above-mentioned problems, and therefore, a gate-type automatic car washing machine has been installed in a coin-type car washing area in order to cope with this problem. However, in order to increase the turnover rate of a car wash, if multiple portal-type automatic car wash machines are installed side by side, it is necessary to install a tank for washing water etc. for each automatic car wash machine, so the space for that is necessary. There are inconveniences that must be secured. In addition, it is necessary to secure the amount of water to be stored in the washing water tank of each car wash machine, secure a heat source to keep the wash water warm, or check the remaining amount and supply of detergent and wax for each car wash machine. However, there is a problem that requires a large maintenance cost and labor for management.

It is an object of the present invention to provide a unit-type car wash system which does not require a large installation area, has low equipment costs, low running costs, and enables high quality car wash without requiring skill. It is in.

[0011]

In order to achieve the above-mentioned object, the present invention is configured to supply washing water or the like from a single supply unit to a plurality of washing units, and the washing unit is provided to a body to be washed. By employing an automatic car washer having a frame configured to be relatively movable, equipment costs and installation space for a washing water tank, a heating device, and the like can be reduced. At the same time, there is a special feature in that high-quality car washing can be easily performed by anyone without requiring skill in operation.

Further, by employing the automatic car washer having the above configuration, it is possible to provide a pressurizing pump for increasing the spray pressure of the nozzle for each washing unit. This facilitates the supply of high-pressure cleaning water and the like to the processing apparatus constituting each cleaning unit, and can reduce the supply pressure from the supply unit to the cleaning unit. Therefore, it is possible to reduce the capacity of the pump for supplying the cleaning water or the like to each cleaning unit, or to reduce the pressure resistance of the supply pipe.

Further, in the present invention, when the frame on which the processing device is mounted relatively moves in one direction along the entire length of the vehicle body, for example, high-pressure spray is applied to the upper surface of the vehicle body by a top nozzle, and the relative movement is performed in the other direction. At this time, it is possible to control the washing by spraying high pressure on both side surfaces of the vehicle body by side nozzles. This concentrates the pressure generated by the pressurized pump on either the top nozzle or the side nozzle, enabling maximum cleaning of the pump capacity at each nozzle, and switching the injection on the forward and return paths to change the body to be washed. The upper surface and the side surface are cleaned. As a result, only one pressurizing pump having an output capable of exhibiting the necessary cleaning power when high-pressure spraying is performed by either the top nozzle or the side nozzle is required. That is, it is possible to wash the entire vehicle body with a sufficient spray pressure by using the minimum equipment.

As shown in FIG. 2, the supply pipe 2 is branched and branched according to the number of cleaning units 3, and the other ends of the branched supply pipes (102a to 102e) are connected to the cleaning unit, respectively. (See FIG. 3). Each of the branched supply pipes (102a to 102e) is formed of a flexible pipe, and can supply cleaning water or the like to each processing apparatus via a pipe in the cleaning unit 3.

A pressurizing pump 7 is provided at an appropriate position on the frame 5 and immediately upstream of each nozzle for high-pressure spraying, and its piping can be supplied to the processing apparatus 6 via the pump. Since the nozzles can be directly pressurized by installing the pressurizing pump 7, there is an effect that a large cleaning ability can be obtained with a small power. Further, the supply pipe 2 and the branched supply pipes 102 only need to have pressure resistance capable of supplying cleaning water or the like from the supply unit 1 to each of the cleaning units 3. It can be adopted.

The processing apparatus 6 includes a top nozzle (TN) 6a constituting a top processing apparatus, a right side nozzle (RSN) and a left side nozzle (LSL) constituting a side processing apparatus.
N) 6b, a left tail nozzle (USNL) and a right tail nozzle (USNR) 6c, and a rinse arch 8 provided at the front of the frame 5 and provided so as to surround the entire body of the vehicle body.

Of the above-mentioned branched supply pipes, the branch pipe 1
02a, 102b, and 102d are connected to the pressurizing pump 7 via the solenoid valve S and the check valve G. The branch pipe 102a of the supply pipe 2a of the washing water is connected to the processing device 6 via the pressurizing pump 7 and also to the rinse arch 8 via the solenoid valve S without passing through the pressurizing pump. It is connected.
In addition, the branched supply pipe 102c of the supply pipe 2c connected to the dilution presoak water tank 13 is directly connected to the rinse arch 8, so that the presoak process is performed only by the supply pressure of the supply pump 21. . Further, an air supply pipe 102e branched from the high-pressure air supply pipe 2e connected to the compressor 23 can be connected to all the processing devices.

The above-described processing device 6 performs the line switching by the solenoid valves S and T in order while the frame 5 reciprocates along the entire length of the vehicle body V in accordance with the selection of the car wash course by the user. It is possible to control so that the washing operation is performed sequentially by injecting washing water or the like from a predetermined nozzle.

FIGS. 4 and 5 show examples of the structure of the cleaning unit 3 in which the processing device 6 and the like are mounted on the gate-shaped frame 5. The frame 5 has wheels 5 as running means on the rails 4.
a enables reciprocation in the full length direction of the vehicle body V. Since the inside of the frame 5 has a large mounting capacity for various facilities, the above-described pressurizing pump 7 can be mounted in addition to the processing device and these driving mechanisms. The aforementioned rinse arch 8 is provided on the entrance side of the vehicle body V to be washed, and the diluted presoak water or the cleaning water can be sprayed on the entire surface of the vehicle body V (see FIGS. 3 and 5).

As described above, the processing devices 6 include the upper surface processing device 26 provided on the ceiling of the gate-shaped frame 5 and the side processing devices 27 provided on both sides of the frame.

The top nozzle 6a provided on the lower surface of the upper surface processing device is horizontally movable via a belt, and the reciprocating movement of the frame 5, the vertical movement of the upper surface processing device 26, and the horizontal movement of the top nozzle 6a are combined. Three-dimensional movement is possible. In addition, the top nozzle 6
a has safety means including a contact type sensor and a non-contact type sensor and a control circuit, and is capable of spraying washing water at a predetermined interval with respect to the upper surface of the vehicle body V.

The side processing device 27 can move up and down the side nozzles 6b, 6b via a motor 30 and a power transmission mechanism 31 provided on the side of the frame 5. In addition, counterweights 32, 32 are attached to the power transmission mechanisms of the respective processing devices to reduce the power required for elevating and lowering the processing devices. Although not shown, the side surface processing device 27 includes an interval adjusting unit that adjusts an interval between the two in accordance with a change in the width of the vehicle body V.
The distance between the side nozzle 6b and the side surface of the vehicle body V can be kept constant.

In addition, although not shown in FIGS. 4 and 5, the side surface processing apparatus is provided with left and right hem nozzles 6c (see FIG. 3).

In each of these processing units, the portal frame 5 reciprocates at least once along the entire length of the vehicle body V on the rails 4, and the vehicle body is washed on the selected car washing course.

The setting of the above-mentioned car-washing course is such that the type of spray is determined for each processing apparatus according to the forward and backward paths when the frame 5 reciprocates in the full length direction of the vehicle body to be washed. There is something like that shown in

[Table 1]

For example, in an automatic car washer of a type in which a frame travels, when the course A shown in the above table is selected, in the first reciprocation of the frame, the forward path is formed by the top nozzle (TN) and the right and left hem nozzles (USNL, USNR). High-pressure spray of detergent water is applied to the upper surface and both sides of the vehicle body, and in the return path, detergent is high-pressure sprayed to both side surfaces of the vehicle body by left and right side nozzles (LSN, RSN). In the second outward pass, rinsing is performed by spraying high-pressure washing water onto the upper surface of the vehicle body with the top nozzle (TN). In the return route, both sides of the vehicle body are similarly sprayed with high pressure using the left and right side nozzles (LSN, RSN). Perform a rinse. The high-pressure spray uses the upper surface and both side surfaces respectively for the round trip and the return path,
By concentrating and switching the pressure generated by the pump, a sufficient cleaning pressure can be applied to each surface.

In the course B, the first outward flow uses the left and right tail nozzles, the left and right side nozzles, and the top nozzle to spray washing water as preliminary washing. In this case, since the pressure generated by the pressurizing pump is distributed to each of the above nozzles, the spray pressure for each nozzle is lower than when the nozzles are properly used in each reciprocating path. Can be pre-washed. Return is pre-soak water supply pump 2
The diluted presoak water is sprayed from the rinse arch 8 by the supply pressure of 1 (see FIG. 2) to make dirt that is difficult to remove rise. In the second outward pass, the top nozzle (TN) and the both tail nozzles (USNL, USNR) are sprayed with high-pressure washing water for rinsing, and in the return pass, both side nozzles (LS) are used.
N, RSN) to rinse the both sides of the vehicle body with high-pressure spray of washing water.

In course C, course B is the first outbound
Simultaneous spraying of washing water is performed from all nozzles in the same manner as above, and the entire body is preliminarily washed only in a one-way process. On the return path, high-pressure wax processing by a top nozzle (TN) is performed. In the second outward pass, both side nozzles (LS
N, RSN), washing water is sprayed from the rinse arch 8 by the supply pressure of the washing water supply pump 19 (see FIG. 2) on the return path, and low pressure rinsing is performed over the entire vehicle body.

In both the B and C courses, the high pressure spray is applied to the top nozzle (TN) and both side nozzles (L
SN, RSN) can be used in the forward and return directions, and the entire body can be washed with a sufficient spray pressure with the minimum equipment.

The courses A, B, and C are selected by the user, and the cleaning operation is performed by any one of the courses A, B, and C or a combination of the courses B and C. . Note that the car wash course varies depending on the type and number of installed processing devices, and these may be appropriately equipped according to the actual situation. Therefore, regarding the setting of the car wash course, it is possible to combine various spray operations in addition to the course described above.

In the above embodiment, the portal frame reciprocates along the entire length of the stopped vehicle body. However, as the frame, a cantilever type or another type of frame is used. It is also possible. Also,
The relative movement between the frame and the vehicle body includes, in addition to the above, a type in which the bogie on which the body is mounted and the frame move in opposite directions, and a type in which only the above-described bogie moves reciprocally with respect to the stopped frame. However, the present invention can be applied to an automatic car washer adopting such a type.

[0043]

According to the present invention, since the washing water and the like can be supplied from a single supply unit to a washing unit having a plurality of automatic car washing devices, the equipment is centralized, so that the management of detergents and waxes is easy. And the amount of water stored and the amount of heat for heating can be saved. In addition, the facility cost and space can be saved, and the degree of freedom of layout in installing a car wash can be improved.

In addition, by employing an automatic car washer as a washing unit in this manner, anyone can easily wash the car without requiring any skill in the car washing operation. Furthermore, it is possible to prevent the user from being disturbed by splashing during the work or splashing water from the next booth.

Further, since a pressurizing pump is installed in each cleaning unit, it is not necessary to use a high pressure pipe for a supply pipe connecting the supply unit and the cleaning unit, so that the pipe can be simplified.

Also, since a pressure pump can be installed immediately upstream of the processing apparatus, even if a high-pressure pipe with a small diameter is used, the length of the pipe leading to the nozzle is short, so that pressure loss due to the pipe is minimized. The spray pressure can be obtained efficiently.

Further, according to the above configuration, the supply pressure from the supply unit to each cleaning unit can be kept low, so that the output of the pump for supplying the cleaning water or the like to each cleaning unit can be reduced and the supply pipe for low pressure can be reduced. Can be adopted, which contributes to a reduction in equipment costs.

In any of the set car washing courses, if the high pressure spray is set so that the top nozzle and both side nozzles are used separately for the forward path and the return path, the selected nozzle can be used for the high pressure spray. Therefore, the entire body can be cleaned with the minimum equipment without reducing the cleaning power.
