BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refueling system in which one vehicle can enter a gate between refueling machines and receive refueling. The present invention relates to a refueling device capable of quickly and efficiently refueling from a machine.

2. Description of the Related Art In a gas station, it is extremely important to refuel a car in as short a time as possible, to eliminate cars waiting for refueling, and to make the flow of cars smooth. Generally, refueling of gasoline and the like to a car in a gas station is performed from a refueling machine provided on an island in the gas station, but in a gas station having a plurality of refueling machines, a refueling machine is provided. It is extremely important to be able to supply the desired oil quickly even if a car enters any gate in between. As a conventional oiling machine, there is always one oiling pump for each oiling machine. For example, a flowmeter is attached to the discharge side of one oiling pump, and its tip is branched to form two branch lines. There is known an oil supply line having a built-in refueling line, a refueling nozzle attached to the tip of each branch line, and two refueling nozzles attached to the front side and the back side of the refueling machine, respectively. Further, as another example of the conventional refueling machine, one in which one of the refueling nozzles attached to the tip of a branch line of the refueling machine is attached to an adjacent refueling machine is known. However, the former refueling machine has a refueling pump for each refueling machine, and a control device must also be provided for each refueling machine. There was a disadvantage that it took time. On the other hand, in the case of the latter refueling machine, each refueling machine has only one refueling nozzle per one line of refueling line. Therefore, when three or more refueling machines are arranged, a gate between adjacent refueling machines is provided. At the same time, when a car enters and tries to refuel, depending on the location of the car's refueling port, it must go around the back of the car to refuel, the nozzle hose must be lengthened, There are drawbacks such as the time and labor required for the removal operation.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks of the conventional fueling machine, and no matter which gate the car enters, and whether the fueling port of the car is on the left or right. It is an object of the present invention to provide a refueling device capable of quickly and efficiently refueling, reducing the time and labor required for installation and maintenance and checking refueling data quickly.

The present invention provides a refueling apparatus characterized in that a display capable of displaying refueling data from one refueling nozzle is installed on both adjacent display surfaces .

Hereinafter, the present invention will be described in detail. The present invention relates to at least one main island and at least two main islands.
It is necessary that two sub-islands are arranged so that the main island and the sub-island are alternately separated by a room for stopping only one vehicle having the maximum body width. The room for stopping only one vehicle having the maximum body width means the interval at which one vehicle receiving refueling can stop and receive refueling, and a margin is added to the maximum vehicle width of the vehicle. Things. The margin is usually selected in the range of 0 to 1 m. Since the maximum width of the vehicle varies depending on the type of the vehicle to be refueled, it may be selected according to the type of the vehicle to be refueled. The number of main islands and sub islands may be appropriately selected according to the size of the site of the gas station.
The arrangement of the main island and the sub-island is not particularly limited as long as the main island and the sub-island are alternately arranged.
Although various arrangement forms such as a linear arrangement, an arc arrangement, and a zigzag arrangement can be taken, the linear arrangement is preferable because the arrangement is orderly and the flow of the automobile can be made smooth.

According to the present invention, it is necessary to install a main refueling machine on a main island and a sub-fueling machine on a sub-island. The main refueling machine is provided with at least two refueling lines including a refueling pump and a branch line. The oil supply pump may be any pump as long as it can discharge oil, but a turbine pump is preferable. The branch line is branched into two branches at a first branch point on the discharge side of the refueling pump. A flow meter is attached to each first branch line, and a second branch downstream of each flow meter is provided. At this point, the fork is further branched into two to form a pair of second branch lines, and each of the second branch lines is provided with a solenoid valve. Two sets are included. The first branch point is
It may be inside the oil supply pump or inside the pipe on the discharge side of the oil supply pump. The second branch point may be located downstream of the flow meter, and its position may be determined as appropriate. The branch line may be any pipe as long as it can feed oil, and can be formed of pipes of various materials such as metal. The main refueling machine is provided with two or more refueling lines. If each refueling line is a different type of oil refueling line, two or more types of oil can be quickly supplied by one refueling machine. It is preferred. Examples of the oil type include regular gasoline, high octane gasoline, and light oil. Usually, it is preferable to provide two or three lines of lubrication lines for each main refueling machine.

In the present invention, a refueling nozzle is attached to a tip of each of the second branch lines of each set in the branch line, and is attached to one end of the second branch line of each set. It is necessary to provide the supplied refueling nozzles to the main refueling machine, and to provide the refueling nozzles attached to the other end of the second branch line of each set to different adjacent sub-fueling machines. As a result, each of the two refueling nozzles per flow meter in one refueling line is attached to each of the adjacent main refueling machine and sub-fueling machine. Therefore, two refueling nozzles are attached to the main refueling machine per one series of refueling lines. Also, when two or more main refueling machines are arranged, one of the second branch lines of each main refueling machine extends to the main refueling machine and the sub-fueling machine sandwiched between the main refueling machines. Thus, a total of two refueling nozzles are provided at the respective ends. When refueling a car that has entered the gate between refueling machines with these refueling nozzles, usually only one of the refueling nozzles attached to the second branch line is used. Can be measured.

Since the fueling nozzles are arranged as described above, fuel can be supplied from both directions of the vehicle entering each gate. Therefore, it is possible to refuel quickly and efficiently by the nearest refueling nozzle. In addition, since the fuel can be supplied from the nearest refueling nozzle, the nozzle hose connected to the refueling nozzle can be shortened, and the nozzle hose can be stored neatly. Furthermore, since the number of refueling pumps is small, there is an advantage that installation and maintenance are easy. Further, as described above, the sub refueling machine is merely provided with an extension line of the second branch line and a refueling nozzle attached to the line as refueling equipment. The size can be reduced, and more gates can be provided even at gas stations on narrow premises. Also, since the size of the sub refueling machine can be reduced, the visibility inside the gas station is improved, and it becomes easy to grasp the intrusion of the vehicle and the refueling situation. The mounting position of the refueling nozzle to the refueling machine is preferably at the opposing surface of each adjacent refueling machine, and particularly preferably at the entry side of the vehicle into the gate at the opposing surface. If the refueling nozzle is installed on the opposing surface of each refueling machine, it is possible to respond quickly to the vehicle that entered the gate and stopped while trying to refuel, especially on the entry side of the vehicle to the gate at this opposing surface. If it is, it can be responded quickly because it is close to the filler port of the car. The refueling machine of the present invention can control the refueling by the control means. This control means controls the driving of the oil pump and the opening and closing of the electromagnetic valve, and any control means having this function may be used. The following are specific examples of the control means. The refueling pump is started by generating a nozzle signal by a nozzle switch, sending the nozzle signal to a controller, and sending a pump drive signal from the controller to the refueling pump based on the nozzle signal. On the other hand, the refueling pump is stopped when the nozzle switch is turned off, the drive signal is cut off, and the refueling pump drive signal from the controller is cut off.

The opening and closing of the solenoid valve is performed by sending an opening and closing signal of the controller to the drive mechanism of the solenoid valve after driving the oil supply pump. The nozzle switch may be provided on the fueling nozzle main body, or may be provided on the fueling machine so as to operate by hanging the fueling nozzle from the fueling machine.
Further, the control means may adjust the drive speed of the oil supply pump by the flow rate of the flow meter, or may adjust the opening / closing degree of the solenoid valve by the flow rate of the flow meter. The refueling device of the present invention is provided with a display capable of displaying refueling data from the refueling nozzle.
The installation place of the indicator is not particularly limited as long as it is a place that is easy to see for a refueling person or a driver, but it is preferable to install the indicator in a straight-ahead direction of a car on each island. In particular, it is preferable that the vehicle is installed in the direction of the straight line of the vehicle near each island so as not to hinder the traveling of the vehicle and to be easily seen by a fueler or a driver. Specifically, it is most preferable to install the refueling machine and the indicator within a range of 6 m in the straight traveling direction of the vehicle. This way,
The driver can see the refueling data very close and does not mistake it. In this case, the display surface of the display is preferably set at a height of 100 to 200 cm from the ground,
Particularly, it is preferable to set the height to 150 to 180 cm. By setting the height in this range, the refueling data can be more easily viewed. Preferred examples of the display include a display having two display surfaces, each display surface being oblique with respect to the straight traveling direction of the vehicle. According to this preferred display, each display surface is oblique and is arranged so as to be easily seen by a refueling person or a driver, so that the refueling data displayed on the display can be grasped immediately after refueling. If the adjacent display surface is slanted inward in the direction of the gate, the driver or refueler of the car entering the adjacent gate will have difficulty seeing the refueling data of the adjacent gate. The user can immediately grasp the refueling data for the refueling vehicle without mistake. In particular, when displaying refueling data from one refueling nozzle on both adjacent display surfaces that face each other at an angle, it is sufficient to look at one of the indicators, because there is some obstacle Even when one of the indicators is not visible, the user can see the other indicators and immediately grasp the refueling data. The refueling data to be displayed can include various data such as the refueling amount of the flow meter, the type of refueling oil, the unit price of the refueling oil, the refueling price, and the consumption tax, but at least the refueling amount of the flow meter is displayed. You need something you can do.

[0011]

Next, an embodiment of the present invention will be described with reference to the drawings. The present invention is not limited by these examples. FIG. 1 is a schematic cross-sectional view schematically showing the piping of a series of oil supply lines of an oil supply device according to one embodiment of the present invention. In the figure, the main island 1 and the sub-island 2 are arranged alternately in a straight line, and the interval between the main island and the sub-island is a width obtained by adding a margin of 80 cm to the maximum body width of one automobile. A main refueling machine 3 is installed on the main island, and a sub refueling machine 4 is installed on each sub-island. The main refueling machine 3 has a built-in refueling pump 5 of a turbine pump. On the discharge side of the refueling pump 5, there are first branch lines 6 and 7 branched into two branches. A flow meter 8 is attached to the first branch line 6, and a flow meter 9 is attached to the other first branch line 7. Further, on the downstream side of the flow meter 8, there are second branch lines 10 and 11 branched into two branches, and similarly on the downstream side of the flow meter 9, the second branch lines branched into two branches. There are branch lines 12,13.

Solenoid valves 14, 15, 16, and 17 are attached to these four second branch lines, respectively, and oil supply nozzles 18, 19, 20, and 21 are attached to the tips thereof. . Refueling nozzles 16, 17 attached to one of the second refueling lines 11, 13 of the pair of second branch lines are attached to the main refueling machine,
Refueling nozzles 20, 21 attached to the other second branch lines 10, 12 are attached to different adjacent sub-fueling machines, respectively. The refueling nozzle may be attached to the refueling machine by means capable of holding and removing the refueling nozzle, and may be attached by, for example, a refueling nozzle box. In this way, since the refueling machine and the refueling nozzle are arranged, when the vehicle enters the leftmost gate between the main refueling machine 3 and the sub refueling machine 4 to receive refueling, the refueling person operates the refueling nozzle 1.
8 or the fueling nozzle 20 can be refueled quickly by the nearest fueling nozzle. Similarly, when a vehicle enters the second gate from the left and receives refueling, it can be refueled quickly by one of the refueling nozzles 19 and 21 which is the nearest refueling nozzle.

FIG. 2 is a schematic plan perspective view of an oil supply device according to one embodiment of the present invention. In the figure, the right main refueling machine 3
Has two built-in refueling lines, and the left main refueling machine 3 has three built-in refueling lines.
On the other hand, a sub-refueling machine 4 between the main refueling machine 3 has a refueling nozzle in which one of a pair of second branch lines of a refueling line built in the main refueling machine 3 is extended, and is attached to the tip thereof. 20 and 21 are provided. Indicators 32 and 33 capable of displaying refueling data are provided in the straight traveling direction of the main refueling machine 3 and indicators 31 and 34 are installed in the straight traveling direction of the sub refueling machine 4. The display surfaces of these display devices are oblique to the gate direction with respect to the straight traveling direction of the vehicle, and the oblique angle is preferably about 45 degrees. This oblique angle is set to make it difficult to see from the adjacent gate, and usually may be appropriately determined so as to achieve this purpose.

In the figure, the refueling data from the refueling nozzle 20 attached to the right side of the sub refueling machine 4 is displayed on a display 31.
The refueling nozzle 1 which is displayed alone or on both the display 31 and the display 32 and which is attached to the left side of the main refueling machine 3
8 is displayed on the display 32 alone or on both the display 31 and the display 32. Refueling data from the refueling nozzle 19 attached to the right side of the main refueling machine 3 is displayed on the display 33 alone or on the display 33. The refueling data by the refueling nozzle 21 attached to the left side of the sub refueling machine 4 is displayed on both the display 34 and the display 34 alone or both the display 33 and the display 34. Since the adjacent display surface is inclined inward in the direction of the gate in this manner, a driver or a refueler of a car entering the adjacent gate becomes difficult to read the refueling data of the adjacent gate. The driver or the driver can immediately grasp the refueling data for the refueling vehicle without mistake. In particular, when the refueling data from one refueling nozzle is displayed on both adjacent display surfaces that face each other at an angle, for example, the refueling data from the refueling nozzle 20 is displayed on both the display 31 and the display 32. If it is displayed, just look at one of the indicators, and even if one of the indicators is not visible due to some obstacle, you can see the other indicators and immediately grasp the refueling data. it can. The display 32 and the display 33 and the display 34 and the display 31 are preferably combined and installed as one display, since it can be installed in a narrow installation place.
FIG. 3 shows an example of the combined display. The display 36 shown in FIG.
7, a storage drawer 38, a storage shelf 39 in the middle, and a display surface 40 in the upper part, are symmetrical left and right, and the back, top, and bottom are all flat. The height of the display surface ranges from 155 to 175 cm from the ground. Further, the main refueling machine 3, the display 32 and the display 34 are installed within a range of about 5 m in the straight traveling direction of the vehicle. For this reason, it is possible to quickly and reliably grasp the refueling data without causing an obstacle to the vehicle. Also, in the figure, a controller 35 is provided behind each display unit and connected to each display unit by a wire. However, this control unit 35 is not limited to each display unit and may be any type. It may be installed at a place. Further, in the figure, the controller 35, the refueling pump 5, the solenoid valves 16, 17,
Wirings for connecting to the controllers 18 and 19 and the flowmeters 8 and 9 are not shown, but wirings for sending signals from these devices to the controller or wires for sending signals from the controller to these devices are provided. Have been. In FIG. 1, the refueling pump 5, the flow meters 8 and 9, and the solenoid valves 14 and 15 are provided in the main body of the refueling machine 3.

Next, a control mechanism of the refueling machine in the embodiment will be described. When the oil supply nozzle 18 or oil supply nozzle 20 attached to the oil supply machine is detached, the nozzle switch attached to the oil supply nozzle is activated, a nozzle signal is generated from the nozzle switch, and the controller 3 is connected through the wiring.
Sent to 5. The controller 35 receives the nozzle signal and sends a refueling pump drive signal to the refueling pump 5 to drive the refueling pump 5. Next, the controller 35 sends the electromagnetic valve 14
Alternatively, a signal for opening the electromagnetic valve 16 is sent, and the electromagnetic valve 14 or the electromagnetic valve 16 is opened. The solenoid valve 14 or the solenoid valve 16
Is transmitted from the flow signal generator 22 to the controller 35.

When refueling is performed by the refueling nozzle 18 or the refueling nozzle 20 when refueling is specified by the refueling nozzle 18 or the refueling nozzle 20, if the refueling nozzle 19 or the refueling nozzle 21 attached to the refueling machine is hung and removed, the refueling nozzle becomes The installed nozzle switch is operated, and a nozzle signal is generated from the nozzle switch.
Sent to The controller 35 receives the nozzle signal,
The refueling pump drive signal is sent to the refueling pump 5, and the refueling pump 5 has already been driven. Since the refueling pump 5 has already been driven, a signal for opening the solenoid valve 15 or the solenoid valve 17 is immediately sent from the controller 35 to the solenoid valve, and the solenoid valve 15 or the solenoid valve 17 is opened. Since the refueling pump 5 has already been driven, it is possible to quickly refuel from the refueling nozzle 19 or the refueling nozzle 21 without waiting for the refueling pump 5 to rise. At this time, if the refueling of the refueling nozzle 18 or the refueling nozzle 20 ends early, when these refueling nozzles are attached to the refueling machine, the nozzle signal is cut off, and the refueling pump drive signal from the controller of this route is also cut off. However, since the nozzle signal of the refueling nozzle 19 or the refueling nozzle 21 is alive, the refueling pump drive signal of the refueling nozzle 19 or the refueling nozzle 21 route is alive from the controller, and the refueling pump 5 is still operating. Thereby, oil can be smoothly supplied from the fueling nozzle 19 or the fueling nozzle 21.

[0017]

The refueling device of the present invention uses the nearest refueling nozzle to the left and right of the vehicle, regardless of which gate the vehicle is in between the refueling machines, and no matter whether the vehicle has a left or right refueling port. Since refueling can be performed from either direction, refueling can be performed quickly and efficiently, and the time and labor required for installation and maintenance can be reduced. Further, the driver or the refueling staff can check the refueling data on one or two indicators, and can quickly and reliably grasp the refueling data.
