Description

Description: TECHNICAL FIELD The present invention relates to a fueling device installed in a gasoline service station for supplying gasoline to an automobile or the like.

[Conventional technology and its problems]

Among such refueling devices, the above ground refueling type has a refueling mechanism such as a refueling pump and a flow meter built in a refueling machine case that stands upright on an island installed on the ground, and a refueling amount indicator is provided on the front of the case. ing.

Then, in order to receive refueling, the vehicle is stopped along the island parallel to the front of the refueling machine case. At this time, the refueling amount is displayed on the display unit, but since the automobile is stopped in front of the refueling machine case in parallel with the refueling unit case as described above, the display unit is positioned laterally of the driver's seat. . For this reason, the driver has to look sideways in order to know the refueling amount, and depending on the position of the refueling port, the driver has to look over the passenger seat or look backward to the oblique rear to see the display, which is often difficult to see. .

Therefore, the refueling amount indicator is separate from the refueling machine case,
It is possible to install it on the wall surface of the building in the gas station, but in such a case, the indicator will be located far away,
It may be difficult to see or may misidentify the indicator of another refueling machine.

On the other hand, to prevent accidents when a car being refueled is started and gasoline is sprinkled around it, causing a fire, or damaging the refueling nozzle or refueling hose, the refueling area and exit route should be connected. There is an idea to prevent the vehicle from starting during refueling by providing a member for preventing exit from the boundary of the vehicle.

Conventionally, for example, a bar is provided at the height of a diamond of a car as a member for preventing the exit from retracting, and when the car stops in a refueling area, it is detected and the front of the car being refueled is blocked by this bar. Had blocked the start of.

With such a means, the bar is installed at a relatively low position on the ground, so it is often hidden behind the car from the driver's seat and the bar cannot be seen directly, and there are cases where the driver tries to start without noticing this. However, the exit prevention function was not sufficient. Also, the bar may not appear unless the vehicle has stopped at the correct position within the refueling area.

The object of the present invention is to eliminate the inconveniences of the above-mentioned conventional examples, to make it easy to see the amount of refueling from the driver's seat of a vehicle being refueled and not to misidentify it, and to function as a member for preventing the retreat of the vehicle being refueled. Another object of the present invention is to provide a refueling device provided with an indicator having the above.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention comprises a refueling machine case installed upright on an island having a refueling area formed in front thereof, and a refueling pump and a flow meter provided in the refueling machine case are connected by a refueling pipe, A refueling hose having a refueling nozzle at its tip is connected to the pipe, and a nozzle hook having a nozzle switch for detecting whether the refueling nozzle is unhooked is provided in the refueling machine case,
An indicator provided with a refueling amount display unit is attached to a moving device that moves between a withdrawal prevention position that appears at the boundary from the refueling area to the exit path and a retreat position withdrawn from the position, and remove the nozzle from the nozzle switch. In response to the signal, the moving device is driven so as to move the indicator from the retracted position to the retracted position, and the indicator is moved from the retracted position to the retracted position in response to the nozzle hooking signal from the nozzle switch. The gist of the invention is to provide the control device for driving the moving device.

[Action]

According to the present invention, after the automobile stops in the refueling area formed in front of the island, the moving device is driven and the indicator is retracted by the nozzle disengagement signal from the nozzle switch by disengaging the refueling nozzle from the nozzle hook. Since the vehicle moves from the position to the boundary between the refueling area and the exit route, this indicator displays the amount of refueling in front of the driver's seat during refueling, and the display obstructs the front of the vehicle to prevent the vehicle from starting. It Then, since the indicator retracts from the boundary between the refueling area and the exit path by the nozzle hooking signal from the nozzle switch by returning the fueling nozzle to the nozzle hook,
When refueling is complete, the car can proceed on the exit route and exit.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an explanatory view showing an embodiment of the oil supply device of the present invention, and FIG.
The figure is a plan view of the same as above. First, explaining the basic configuration of the refueling device, the figure shows a ground-fixing type refueling device. As is well known, the refueling case 2 is erected on an island 1 installed on the ground. In the refueling machine case 2, a refueling pipe 3 communicating with an underground oil storage tank (not shown) is started up, and a refueling pump 5 connected to a refueling motor 4 and a flow rate pulse transmitter 6 are connected in the middle of the refueling pipe 3. The flowmeters 7 are sequentially arranged.
Then, the end portion of the refueling pipe 3 is led out of the refueling machine case 2,
A refueling hose 9 having a refueling nozzle 8 at its tip was connected to this, and a nozzle switch 10 that was turned on and off by moving the refueling nozzle 8 on and off was provided on a nozzle hook 10 formed on a side portion of the fuel tank case 2. .

According to the present invention, in the refueling device having such a structure, the display 12 is mounted above the side part of the refueling machine case 2 so as to be rotatable in the horizontal direction via the moving device 13 such as a rotating motor. This rotation range is indicated by the solid line in FIG.
And 180 degrees relative to the lateral extension direction of the lubricator case 2 to the position orthogonal to the case 2 relative to the lubricator case 2 at a position of 90 degrees. A fixed position sensor using a limit switch etc. that detects the position of the display 12 when it is positioned in the extension direction and the orthogonal direction.
14 is provided on the case 2 of the fuel dispenser.

The display 12 is provided with a stop display section 15 for displaying characters such as "engine stopped during refueling" as an information display section, and a refueling amount display section 16, and detects a stopped car in the refueling area A. The sensor 17 is provided.

In this way, the control device 18 using the microcomputer is arranged in the fuel case 2, and the outputs from the nozzle switch 11, the sensor 17, the fixed position sensor 14 and the flow rate pulse transmitter 6 are shown in the block diagram of FIG. The signal is introduced into the control device 18, and the control signal from this is introduced into the stop display unit 15, the refueling amount display unit 16, the moving device 13, and the drive unit of the refueling motor 4. As is well known in the art, the control unit 18 is a central processing unit 19,
Input / output device 20, storage device (RAM) 21, storage device (ROM) 22
And a clock circuit 23.

At the boundary from the refueling area A formed in front of the island 1 where the refueling device is installed as described above to the exit route,
The display 12 is provided so as to be retractable.

Next, the usage and operation will be described with reference to the flow chart of FIG. 4. During non-refueling, the indicator 12 is positioned laterally of the refueling machine case 2 in parallel with it, as shown in FIG. The car stopped near the refueling machine to get refueling,
When the refueling nozzle 8 is removed from the nozzle hook 10, the nozzle switch 11 is turned on and a nozzle removal signal as a refueling start signal enters the control device 18 (step a), and the control signal from here serves to refuel the display unit 12. At the same time as the previous display of the amount of refueling displayed on the amount display unit 16 is reset to zero, the display "Stop engine during refueling" is displayed on the stop display unit 15 and the refueling motor 4 starts to rotate (step ).

At the same time, the output is also output to the moving device 13, and as a result, the indicator 12 starts to horizontally rotate about the moving device 13 from the side to the front of the fuel filler case 2 (step C). At this time, when the vehicle stops without protruding to the front of the refueling area A, the sensor 17 attached here does not detect the vehicle (step 2), that is, the display 12 indicates the vehicle. Since it does not come into contact with, the rotation is continued, and it is rotated to a position orthogonal to the fuel filler case 2 (step E). And the fixed position sensor 14
When it is detected that 12 has reached this position, the rotation stops, and the indicator is located at the boundary between the refueling area A and the exit route.

On the other hand, if the vehicle runs off the refueling area A and stops near the indicator 12 in front of it, the sensor 17 detects the presence of the vehicle before the indicator 12 reaches the stop position (step d). 12 stops diagonally with respect to the refueling machine case 2 at that position.

In this way, when the refueling nozzle 8 is inserted into the gasoline tank of the automobile for refueling, the flow rate of gasoline pumped up from the underground oil storage tank by the refueling motor 4 and the refueling pump 5 is measured by the flow meter 7 and the flow rate pulse transmitter. 6 is sent to the control device 18 as a pulse signal, and by its function the oil supply amount display section
It is displayed in 16 as the amount of refueling. At this time, since the indicator is located near the front of the automobile and almost at the height of the driver's eyes, the amount of refueling can be easily seen from the driver's seat.

In this way, during refueling, the indicator 12 is located in front of the car and closes it to prevent the car from starting, and the stop indicator 15 displays the text "engine stopped during refueling" Prompt or confirm that the engine is switched off.

Since the display of "engine stopped during refueling" and the display of refueling amount are made at approximately the eye level of the driver as described above, not only the precautions and refueling amount during refueling are easy to see, but It is easy to recognize that is blocked.

When refueling is completed and the refueling nozzle 8 is returned to the nozzle hook 10,
The nozzle application signal as the refueling end signal enters the control device 18 (to step), and by its action, the stop indicator 15 of the indicator 12
The word "engine stopped during refueling" displayed on disappears and the refueling motor 4 stops at the same time (stepped).

Similarly, when the indicator 12 is output to the moving device 13 and the display 12 starts horizontal rotation in a direction parallel to the fuel case 2 (step C), and rotates to the lateral extension direction of the case 2, the fixed position sensor 14 is detected. Detects this (stepping), which causes the display 12 to stop at this position.

Thus, if the indicator 12 is caught from the front of the vehicle, that is, the exit path, the vehicle will start and exit the gas station.

In the first embodiment described above, the display 12 is configured to be horizontally rotated, but the present invention is not limited to this, and the display 12 is used as the second embodiment as shown in FIGS. May be rotated vertically. In this case, the sensor 17 is attached to the lower part of the display 12 facing downward. Since the other components are the same as those in the first embodiment,
The same reference numerals are given and detailed description is omitted here.

Further, a pillar may be provided separately from the fuel filler case, and the moving means and the display amount may be provided on the pillar.

〔The invention's effect〕

As described above, in the refueling device of the present invention, the refueling amount is easy to see from the driver's seat because the indicator moves near the front of the vehicle during refueling. In addition, the indicator that blocks the front of the vehicle in this way also serves to prevent the vehicle from exiting during refueling.
In this case, the indicator can be seen directly in the immediate vicinity, and even if the vehicle is not parked at the correct position in the refueling area, the exit blocking member will surely appear if the refueling is started, It has a large exit prevention function.
