Description

TECHNICAL FIELD The present invention relates to an oil supply device installed in an oil supply station for supplying gasoline or the like to an automobile.

[Conventional technology]

Fuels for automobiles include oils such as gasoline and light oil,
One refueling machine case is shared and a refueling hose for gasoline and a refueling hose for light oil are led out from here.

Then, for example, "Regular" is added to an appropriate portion of the fuel filler case.
Characters indicating the type of gasoline such as “Super” or “light oil” or light oil are added to indicate which kind of oil the refueling device or refueling hose handles. For regular vehicles or super gasoline, diesel vehicles are refueled with diesel fuel.

[Problems to be solved by the invention]

In this way, attention has been paid to the fact that it has been conventionally determined whether the refueling device or refueling hose is for gasoline or light oil only by the letters on the refueling machine case, etc. Or, if the oil type is indicated at a position apart from the hand-held refueling hose, it may be mistaken for another oil type. As a result, a gasoline vehicle may be accidentally refueled with diesel oil, or vice versa, gasoline may be refueled with a diesel vehicle.
In the latter case, the engine of the car may simply not be started, but in the former case, engine troubles are particularly large and often very dangerous.

Therefore, conventionally, for example, JP-A-55-20133 and JP-A-53-1.
As can be seen in Japanese Patent No. 12516, when the refueling nozzle is removed, some types of oil that can be refueled by the refueling nozzle are displayed on the display, but since it is displayed for all types of oil, it is possible to prevent erroneous refueling in particular. There may be insufficient consideration for the required diesel fuel.

An object of the present invention is to eliminate the disadvantages of the conventional example, and to provide a refueling device that can prevent the accidental refueling of light oil to a gasoline vehicle and can ensure the safety of the vehicle, which can cause a particularly large danger.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides an oil supply device for housing a gas oil supply system for light oil and gasoline, and controlling the drive of an oil supply pump of the corresponding oil type by means of a nozzle switch that is operated by unplugging the oil supply nozzle. A notification means is provided, and a fuel supply request determination means for operating the oil type notification means for a certain period of time is provided by a signal from the nozzle switch when the gas oil supply nozzle is removed from the nozzle hook. It is a gist to prevent a gasoline vehicle from being refueled with light oil by notifying that there is a certain time by sound.

[Action]

According to the present invention, when the refueling nozzle for refueling light oil is removed, the annunciator operates for a certain period of time with the output from the refueling request determination means by the output of the nozzle removal signal from the refueling nozzle. A sound informs that it is for light oil.
The notification by the sound is made only when the fueling nozzle for light oil refueling is removed, and is not performed even when the fueling nozzle for gasoline refueling is removed.

Further, unlike the conventional display, the notification by sound is understood and not overlooked while working.

Furthermore, since only the light oil that is rarely used is struck, it becomes particularly noticeable.

Moreover, since the notification by this sound is only for a fixed time,
If the time is limited to the start of refueling, for example, there will be no noise and no noise during refueling thereafter.

〔Example〕

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

FIG. 1 is a partially cutaway front view showing an embodiment of a fueling device of the present invention, and FIG. 2 is a side view of the same. First, the overall configuration of the fueling device will be described. As an example, on an island 1 installed on the ground. An oiler case 2 composed of an upper case 2a, a pillar 2b and a lower case 2c is erected, and an oil supply pipe 3a connected to an underground tank (not shown) is erected in the lower case 2c. In the middle of the oil supply pipe 3a. As an oil supply mechanism, an oil supply pump 5a connected to an oil supply motor 4a and a flow meter 7a connected to a flow rate pulse transmitter 6a are sequentially arranged, the end of the oil supply pipe 3a is outside the lower case 2c, and the root of the spring 12 is provided. After being supported by such an elastic member and started up, it was connected to an oil supply hose 8a that was suspended, and an oil supply nozzle 9a was provided at the tip of this oil supply hose 8a. Further, a nozzle hook 10a is provided on the front surface of the lower case 2c, and a nozzle switch 11a which is interlocked with the hanging of the oil supply nozzle 9a is provided here.

Then, the same two oil supply hoses 8b and 8c as the oil supply hose 8a are juxtaposed in parallel with the oil supply hose 8a and hung from the front of the lower case 2c to distinguish them for light oil, super gasoline, and regular gasoline, respectively. Similarly, three oil supply hoses 8a ', 8b', 8c 'are hung on the back surface in the same manner. Further, a total of 6 sets of the oil supply mechanism composed of the oil supply motor 4a, the oil supply pump 5a, the flow rate pulse transmitter 6a, the flow meter 7a and the like are housed in the lower case 2c, a total of 6 sets, and the oil supply hose 8a is stored in each of them. Connect ~ 8c '. Then, a control device 13 that uses, for example, a conventionally well-known microcomputer or the like for controlling these oil supply mechanisms is housed in the lower case 2c.

On the other hand, a lighting device such as a fluorescent lamp is arranged in the upper case 2a, and the front, rear, left, and right panel surfaces are made to correspond to the oil types of the refueling hoses 8a to 8c ', and in the same arrangement as "Regular" and "Super". The display character 16 indicating the oil type such as "light oil" is noted. At the center of the lower part of the upper case 2a, for example, a buzzer 14 is attached as an alarm activated by sound from the outputs of the front and rear nozzles 11a, 11a 'for light oil, and the refueling ends at the left, right, front and rear positions of the buzzer 14. 2 flashing lamps 15 for display, 2 for front and 4 for back
Arranged individually.

The strut 2b connecting the upper case 2a and the lower case 2c is provided with oil types such as "light", "S", and "R" on the front and rear surfaces thereof, and a flushing lamp 17a for indicating that refueling is being performed. , 17b, 17c are provided, and an indicator 18 common to each oil type that displays the amount of oil and the amount of oil supplied is provided, and an emergency stop button 19 for turning off the main power to the oil supply device, a card reader 20,
An input / output keyboard 21 and a sub display 22 are provided.

Thus, as shown in the block diagram of FIG. 3, nozzle switch 11a for light oil and nozzle switch 11 for super gasoline
b, the nozzle removal signal and the nozzle hooking signal from the regular gasoline nozzle switch 11c are introduced into the refueling request control means 23 of the control device 13, and the output signal from this is supplied to each of the refueling nozzle switches 11a, 11b and 11c. Introduced into the refueling motors 4a, 4b, 4c of the refueling system and the flushing lamps 17a, 17b, 17c that indicate refueling, respectively.

Then, as a light oil notification circuit, in particular, the nozzle removal signal from the light oil nozzle switch 11a is used as a timer 24
Was introduced into the drive circuit of the buzzer 14 via. The nozzle removal signal from the light oil nozzle switch 11a 'on the back side is also introduced into the drive circuit of the buzzer 14 via the time counting means 24.

Also, as the fuel supply amount display circuit, flow pulse signals from the flow pulse generators 6a, 6b, 6c for light oil, super gasoline, and regular gasoline, and unit price storage means for light oil, super gasoline, and regular gasoline, respectively.
The output signal from 25 and the output signal from the refueling request judging means 28 are introduced into the calculating means 26, and the calculation result here is introduced into the display 18.

As the refueling completion notification circuit, the flow rate pulse signal, the output signal from the refueling request determination means 23, and the count signal when the amount of oil discharged from the computing means 26 is, for example, 0.1 or more are sent to the refueling completion determination means 27. Then, the output signal from this was introduced into the flushing lamp 15.

Next, the usage and operation will be described with reference to the flowcharts of FIGS. 4 to 6. First, in the case of supplying light oil, among the three oil supply nozzles 9a, 9b, 9c arranged in parallel, the oil supply for light oil is performed. If the nozzle 9a is removed from the nozzle hook 10a, the nozzle switch 11a is turned on in synchronization with this (step a) This nozzle removal signal enters the refueling request determination means 23,
By the function of the judging means 23, the refueling mechanism for other regular gasoline and super gasoline is locked, and at the same time, the refueling motor 4a for light oil is turned on, the refueling pump 5a is driven, and the flushing lamp 17a for indicating refueling blinks. Further, the unit price of the light oil stored in the unit price storing means 25 is extracted and enters the calculating means 26. At the same time, a buzzer activation signal is output to the timekeeping means 24 (step B). As shown in the flow chart of FIG. 5, when a buzzer operation signal is input to the timing means 24 (stepping), the buzzer 14 is activated by the signal from the timing means 24.
Is activated (steps), the operation means 24 outputs an operation signal for a preset time, for example, 3 seconds, and the buzzer 14 sounds (stepwa), and the operation signal stops after 3 seconds have elapsed. The buzzer 14 stops (step power).

The buzzer 14 makes a sound to notify that the refueling nozzle 9a removed in this way is for light oil, and prompts to confirm whether it is mistaken for another oil type. In addition, the nozzle removal signal enters the calculating means 26 as a reset signal and the previous amount of oil supply is reset (step C). If the oil supply nozzle 9a is inserted into the tank of the vehicle and oil is supplied, the flow pulse generator 6a for light oil is supplied. A flow rate pulse signal is issued from the device (step 2), and this enters the calculation means 26 to calculate the amount of oil supply, and the amount of oil supply is calculated based on the unit price of light oil drawn from the unit price storage means 25 and the value is displayed. Is displayed in (Step E). The calculation of the amount of refueling is performed until the refueling is finished, the refueling nozzle 9a is hung on the nozzle hook 10a, and the nozzle switch 11a is turned off (step F). When the nozzle switch 11a is turned off, the lock of other oil types is released, and the operation of the oil supply motor 4a and the lamp 17a is stopped (step).

Next, the blinking of the flushing lamp for notifying the operator that the refueling is finished will be described. As shown in the flow chart of FIG. 6, when refueling starts and the refueling amount counted by the computing means 26 reaches, for example, 0.1 or more (step yo), the refueling end determining means 27 causes the flow rate pulse signal to be output within a fixed time, for example, 2 seconds. It is determined whether or not is newly input (step, check).

Now, if the tank of the car is full and the valve of the refueling nozzle 9a is closed manually (in the case of an auto nozzle, the valve is automatically closed), the flow rate pulse signal will not be input within 2 seconds. From (step), refueling end determination means 27
Outputs to the flash lamp 15 that indicates the end of refueling and blinks it (steps). In addition, this lamp 15
Since four are provided on the lower surface of the upper case 2a, it is possible to know the blinking of the lamp 15 from any side with respect to the refueling machine case 2 from anywhere. The time until the next transmission of the flow rate pulse signal is set to 2 seconds, assuming that the valve of the fueling nozzle 9a is repeatedly opened and closed to refuel little by little when the tank is almost full. This is to prevent the flashing lamp 15 from blinking even in the case.

In this way, when the refueling nozzle 9a is still inserted into the tank of the vehicle even though the valve of the refueling nozzle 9a is closed and refueling is completed, the flashing lamp 15 notifies this. To do. Then, if the fueling nozzle 9a is removed from the tank and returned to the nozzle hook 10a, the nozzle switch is turned off (step), and the flashing lamp 15 stops blinking by the nozzle hook signal (step ne).

If the valve automatically closes with the auto nozzle,
If the fuel supply nozzle 9a is not returned to the nozzle hook 10a (step S) and the valve is manually opened again to refuel, the flow rate pulse signal is newly input to the fuel supply end determination means 27 (step), so at this point The flashing lamp 15 stops blinking (stepner).

The above is the case of refueling light oil, but to refuel super gasoline, in the same way as for light oil, remove the refueling nozzle 9b for super gasoline from the nozzle hook 10b to turn on the nozzle switch 11b (step check). ), The nozzle removal signal from here enters the refueling motor 4b for super gasoline through the refueling request determination means 23, which rotates to turn on the refueling pump 5b, and the flushing lamp 17b during refueling blinks, and at the same time super gasoline The gasoline unit price for gasoline is output from the unit price storing means 25 to the calculating means 26 (step). Then, similarly to the case of the light oil refueling described above, the previous refueling amount is reset (sweep ha), and the refueling nozzle
The fuel is supplied by discharging super gasoline from 9b. In this case, the nozzle switch for super gasoline 11
Since the nozzle removal signal from b is not output to the buzzer 14, it does not operate.

When refueling with regular gasoline, the operation is exactly the same as with super gasoline.

〔The invention's effect〕

As described above, the refueling device of the present invention makes noise only when the light oil nozzle is removed when the refueling nozzles for handling light oil and gasoline are provided in parallel in one refueling machine case. No sound is produced even if the fueling nozzle for fuel oil is removed, so it is possible to change the operation mode when the fuel oiling nozzle is removed, and it is possible to reliably confirm that the fueling nozzle is for light oil, and it can be mistaken for gasoline. It is possible to prevent accidental refueling of light oil, prevent engine troubles in gasoline vehicles, and ensure safety.

Also, unlike the conventional display by sound, the notification by sound is understood and not overlooked while working,
There is certainty, and since only light oil that is rarely used is made to sound, it becomes particularly noticeable.

Moreover, since the notification by this sound is only for a fixed time,
If the time is limited to the start of refueling, for example, there will be no noise and no noise during refueling thereafter.
