Description

  The present invention relates to a fueling device that supplies fuel oil to an automobile, and more particularly to a fueling device that functions effectively in a self-service fueling station where a customer himself supplies fuel.

Self-service refueling stations where customers themselves refuel, not refueling station workers, are widespread.
At a self-service filling station, a customer who is unfamiliar with refueling refuels, so it is difficult to finely adjust the opening of the valve of the refueling nozzle. Therefore, when the fuel supply port of the fuel tank of the automobile is bent, if the discharge amount is large, the liquid level sensor detects the oil that rebounds, and the fuel supply is stopped many times, resulting in poor fuel supply efficiency.
In addition, when adding fuel after the fuel tank is almost full, oil may overflow if the discharge amount is large.

The oil supply apparatus shown in Patent Document 1 supplies oil with a reduced flow rate when a liquid level sensor provided in an oil supply nozzle detects liquid.
This is effective, but there is no countermeasure when the liquid level sensor detects liquid at the beginning of refueling. For this reason, it is impossible to efficiently supply fuel to a vehicle in which the fuel filler port of the fuel tank is bent.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic diagram of a fueling device of the present invention. In FIG. 1, an oil supply pipe 3 connected to an oil storage tank (not shown) is disposed in a housing 2 of the oil supply apparatus 1. The oil supply pipe 3 includes a pump 5 driven by a motor 4, a flow control valve 6, and A flow meter 8 having a flow rate pulse transmitter 7 is interposed.

An oil supply nozzle 10 is provided at the tip of an oil supply hose 9 connected to the oil supply pipe 3, the oil supply nozzle 10 is attached to a nozzle hook 11, and a nozzle switch 12 is provided on the nozzle hook 11.
The oil supply nozzle 10 is a so-called auto nozzle that automatically closes when a liquid level sensor provided in the discharge pipe detects the liquid.
Further, the housing 2 is provided with an oil supply amount indicator 13, a motorcycle oil supply indicator 14, a voice generator 15, a data input device 16, and an oil supply control device 17.

As shown in the block diagram of FIG. 2, an on / off signal is input from the nozzle switch 12 to the oil supply control device 17, and a flow rate signal is input from the flow rate pulse transmitter 7 to the oil supply control device 17 and set from the data input device 16. A signal is input to the fuel supply control device 17.
Then, a start / stop signal is output from the oil supply control device 17 to the motor 4, a valve opening signal is output to the flow control valve 6, an oil supply amount display signal is output to the oil supply amount indicator 13, and the voice generator 15 is output. A fueling guidance signal is output, and a lighting / extinguishing signal is output to the motorcycle fueling indicator 14.

FIG. 3 is a schematic diagram of an example of the flow control valve 6.
In FIG. 3, the main flow path 21 is connected to the oil supply pipe 3, and the main valve 22 interposed in the main flow path 21 is biased by a spring 23.
The main flow path 21 upstream of the main valve 22 and the valve chamber 24 of the main valve 22 are connected by a thin tube 25. The narrow tube 25 is provided with a throttle 26 and an electromagnetic valve 27.
The valve chamber 24 of the main valve 22 and the main flow path 21 on the downstream side of the main valve 22 are connected by a thin tube 28. The narrow tube 28 is provided with a throttle 29 and an electromagnetic valve 30.

The throttles 26 and 29 are set so that the flow rate of the narrow tube 25 when the solenoid valves 27 and 30 are opened is larger than the flow rate of the narrow tube 28.
The narrow tube 31 bypassed to the narrow tube 28 opens the main valve 22 at the time of a power failure or the like. If the on-off valve 32 interposed in the narrow tube 31 is manually opened, the main valve 22 can be opened with hydraulic pressure.

When the electromagnetic valve 27 is closed and the electromagnetic valve 30 is opened with the flow control valve 6 configured as described above, the liquid in the valve chamber 24 flows out to the main flow path 21 through the narrow tube 28 and resists the force of the spring 23. Then, the main valve 22 opens with the hydraulic pressure of the main flow path 21.
When the electromagnetic valve 30 is closed and the electromagnetic valve 27 is opened, the liquid in the main flow path 21 flows into the valve chamber 24 via the narrow tube 25, and the main valve 22 is closed in combination with the force of the spring 23.
When the solenoid valves 27 and 30 are simultaneously opened, the liquid flowing into the valve chamber 24 through the narrow tube 25 is larger than the liquid flowing out from the valve chamber 24 through the thin tube 28, so that the main valve 22 is slowly closed.
Further, when the electromagnetic valves 27 and 30 are closed at the same time, the liquid in the valve chamber 24 is confined and the main valve 22 can be maintained at a desired valve opening.

Next, based on FIG. 4, FIG. 5, operation | movement of a fueling apparatus is demonstrated.
When the vehicle is stopped in the fueling area of the fueling device 1 and the fueling nozzle 10 is removed from the nozzle hook 11 and an ON signal is input from the nozzle switch 12 (ST1), the fueling control device 17 displays the fueling amount indicator 13 in step ST2. The previous lubrication amount that was displayed is returned to zero, and an activation signal is output to the motor 4. The pump 5 is driven by the motor 4 (a in FIG. 5), the electromagnetic valves 27 and 30 are opened (a in FIG. 5), the main valve 22 (FIG. 3) of the flow control valve 6 is temporarily closed, and the basic state is reached. Become.

When the fueling nozzle 10 is inserted into the fueling port of the automobile and the valve of the fueling nozzle 10 is opened (b in FIG. 5), a full open signal is output to the flow control valve 6 (ST2), and the electromagnetic valve 27 is closed (in FIG. 5). b).
Thereby, refueling is started at a refueling amount of 30 liters / minute.
The fuel oil in the oil supply pipe 3 is supplied from the oil supply nozzle 10 into the fuel tank of the automobile through the pump 5, the flow control valve 6, the flow meter 8, and the oil supply hose 9.
The oil supply control device 17 calculates the flow rate signal of the flow rate pulse transmitter 7 of the flow meter 8 and displays the calculated oil supply amount on the oil supply amount display 13.

When the oil level is detected by the liquid level sensor and the valve of the oil supply nozzle 10 is closed before the oil supply amount reaches a certain amount (for example, 20 liters) (c in FIG. 5), the oil supply control device 17 detects the absence of the flow signal. A stop of refueling is detected (Y in ST3), and a close signal is output to the flow control valve 6 (ST4). The flow control valve 6 receives the close signal, opens the electromagnetic valve 27 (c in FIG. 5), and closes the main valve 22.
When the amount of oil supply at this time is within a certain amount, for example, within 2 liters (ST5 is Y), and the valve of the oil supply nozzle 10 is opened (d in FIG. 5), a full open signal is output to the flow control valve 6 (ST6). .
In the flow control valve 6 that has received the full open signal by opening the valve of the nozzle 10, the electromagnetic valve 27 is closed (d in FIG. 5), and the main valve 22 is opened. As a result, the flow control valve 6 is fully opened at 30 liters / minute.

Then, refueling is resumed at a refueling amount of 30 liters / minute.
If the valve of the oil supply nozzle 10 is closed again before the amount of oil supply reaches 20 liters (ST7 is Y: e of FIG. 5), the oil supply control device 17 closes the flow control valve 6 (ST8: e of FIG. 5).
If the amount of oil supply at this time is within 2 liters (ST9 is Y) and the valve of the oil supply nozzle 10 is opened in this state (f in FIG. 5), an intermediate open signal is output to the flow control valve 6 (ST10). .
When the valve of the oil supply nozzle 10 is opened (f in FIG. 5) and a middle open signal is output, the electromagnetic valve 27 is closed (f in FIG. 5) in the flow control valve 6 (see FIG. 3), and the flow control valve 6 The main valve 22 is opened (f in FIG. 5). After that, if the electromagnetic valve 30 is closed at a predetermined timing (g in FIG. 5), the flow control valve 6 is in an open state (for example, a state in which refueling of 20 liter / min is possible).

  When the valve of the fueling nozzle 10 is closed (ST11 is Y: h in FIG. 5), the flow control valve 6 is closed (h in FIG. 5), and the voice generator 15 is activated (ST12). “Please be careful of overflow.”

When the valve of the fueling nozzle 10 is opened (i in FIG. 5), the fueling control device 17 outputs a small opening signal to the flow control valve 6 (ST13).
When the small opening signal is output, in the flow control valve 6 (see FIG. 3), the electromagnetic valve 27 is closed (i in FIG. 5), and the main valve 22 is opened. After that, by closing the electromagnetic valve 30 at a predetermined timing (j in FIG. 5), the flow control valve 6 is in a small open state (for example, a state where oil can be supplied at 15 liters / minute).
Thereby, refueling is resumed at a flow rate of 15 liters / minute.

  When the valve of the oil supply nozzle 10 is closed (Y in ST14, k in FIG. 5), the oil supply control device 17 outputs a close signal to the flow control valve 6 to close the flow control valve 6 (k in FIG. 5: ST15). The voice generator 15 is actuated, and the voice “Lubrication has stopped. Be careful of overflow” (ST15).

When the valve of the oil supply nozzle 10 is opened, a slight opening signal is output to the flow control valve 6 (ST16).
In the flow control valve 6 that has received the slight opening signal, the electromagnetic valve 27 is closed (l in FIG. 5). After that, by closing the electromagnetic valve 30 at a predetermined timing (m in FIG. 5), the flow control valve 6 is in a slightly opened (for example, 8 liter / min) oil supply state.
Thereby, refueling is resumed at a flow rate of 8 liters / minute.

Here, in normal refueling, after m in FIG. 5, the valve of the refueling nozzle 10 is closed (n in FIG. 5), the valve of the refueling nozzle 10 is opened (l in FIG. 5), and the solenoid valve is at a predetermined timing. The process of closing 30 and slightly opening (for example, 8 liters / minute) to a refueling state (m in FIG. 5) is repeated until the refueling nozzle 10 is hung on the nozzle hook 11.
In the case of so-called preset fueling, when the valve of the fueling nozzle 10 is closed again (ST17, n in FIG. 5), the fueling control device 17 outputs a close signal to the flow control valve 6 and closes the flow control valve 6 (FIG. 5 n to p), the voice generator 15 is activated, and the voice “She has finished refueling. Please check out” (ST18). Then, the process proceeds to step ST19.

  When refueling is finished, the refueling nozzle 10 is hung on the nozzle hook 11 and the nozzle switch 12 is turned off (Y in ST19), the refueling control device 17 outputs a stop signal to the motor 4 (ST20), and the pump 5 is driven. Then, the motor 4 stops (p in FIG. 5), and the refueling operation is finished.

As described above, in the fueling device according to the illustrated embodiment, first, a large flow amount of fuel is performed, then a medium flow amount of fuel is performed, a small amount of fuel is performed, and finally, a small amount of fuel is fed. Since it is executed, refueling is performed efficiently, and it is possible to fill up to full tank without overflowing.
Then, if a refueling stop occurs twice within a certain refueling amount while a large flow rate is being supplied, it is determined that the shape of the refueling port in the automobile fuel tank is not suitable for a large flow rate, and a medium flow rate refueling Execute. Therefore, it is possible to efficiently supply oil to various shapes of the fuel filler opening in the automobile.

If the amount of fuel supply reaches a certain amount (for example, 20 liters) before the fuel supply is stopped in step ST3 (ST21), the fuel supply control device 6 should reduce the free capacity of the fuel tank of the automobile and reduce the flow rate. And step ST10 and subsequent steps are executed.
The oil supply control device 17 controls the oil supply as shown in the time chart of FIG. In other words, refueling starts at a large flow rate of 30 liters / minute, and when refueling is stopped up to 20 liters without stopping, refueling is at a medium flow rate of 20 liters / minute, and small at 15 liters / minute when refueling is stopped. When the oil supply is stopped again, the oil is supplied at a fine flow rate of 8 liters / minute.

After refueling at a fine flow rate of 8 liters / minute, in normal refueling, the valve of the refueling nozzle 10 is closed (n in FIG. 5), the valve of the refueling nozzle 10 is opened (l in FIG. 5), and a predetermined timing Then, the process of closing the solenoid valve 30 and setting it to a slightly open (for example, 8 liter / min) oil supply state (m in FIG. 5) is repeated until the oil supply nozzle 10 is applied to the nozzle hook 11.
In the case of so-called preset oil supply, when the valve of the oil supply nozzle 10 is closed again (n in FIG. 5), the oil supply control device 17 outputs a close signal to the flow control valve 6 and closes the flow control valve 6 (FIG. 5). n to p), the voice generator 15 is activated, and the voice “Since refueling has been completed.

  In this way, when a large amount of oil is supplied to a certain amount during refueling, a medium amount of refueling is executed.Therefore, a large amount of oil must be supplied before the liquid level sensor detects the liquid and stops refueling. Can be executed. Therefore, the refueling time can be shortened.

If the amount of fuel supply reaches a certain amount (for example, 20 liters) before the fuel supply is stopped in step ST7 (ST22), the fuel supply control device 6 should reduce the free capacity of the fuel tank of the automobile and reduce the flow rate. And step ST10 and subsequent steps are executed.
As shown in the time chart of FIG. 7, the oil supply control device 17 starts refueling at a large flow rate of 30 liters / minute, and when refueling is stopped up to 20 liters with only one refueling stop, The oil supply is performed at a flow rate, the oil supply is performed at a small flow rate of 15 liters / minute when the next oil supply is stopped, and the oil is supplied at a fine flow rate of 8 liters / minute when the oil supply is stopped again.

After refueling at a fine flow rate of 8 liters / minute, in normal refueling, the valve of the refueling nozzle 10 is closed (n in FIG. 5), the valve of the refueling nozzle 10 is opened (l in FIG. 5), and a predetermined timing Then, the process of closing the solenoid valve 30 and setting it to a slightly open (for example, 8 liter / min) oil supply state (m in FIG. 5) is repeated until the oil supply nozzle 10 is applied to the nozzle hook 11.
In the case of so-called preset oil supply, when the valve of the oil supply nozzle 10 is closed again (n in FIG. 5), the oil supply control device 17 outputs a close signal to the flow control valve 6 and closes the flow control valve 6 (FIG. 5). n to p), the voice generator 15 is activated, and the voice “Since refueling has been completed.

  Even in this case, when a large amount of oil is supplied, if a certain amount of oil is supplied, an intermediate amount of oil is executed.Therefore, a large amount of oil is supplied until the liquid level sensor detects the liquid and stops refueling. This can be done and the refueling time can be shortened.

In step ST5, when the amount of fuel supply is 2 liters or more, in other words, when 2 liters or more is already supplied at the time of the first stop of fueling, the fuel supply control device 6 determines that the free capacity of the fuel tank of the automobile is sufficient. It is determined that it is better to reduce the flow rate, and step ST13 and subsequent steps are executed.
As shown in the time chart of FIG. 8, the refueling control device 17 starts refueling at a large flow rate of 30 liters / minute, and if the refueling amount is 2 liters or more at the first refueling stop, When the oil supply is stopped again, the oil is supplied at a fine flow rate of 8 liters / minute.

After refueling at a fine flow rate of 8 liters / minute, in normal refueling, the valve of the refueling nozzle 10 is closed (n in FIG. 5), the valve of the refueling nozzle 10 is opened (l in FIG. 5), and a predetermined timing Then, the process of closing the solenoid valve 30 and setting it to a slightly open (for example, 8 liter / min) oil supply state (m in FIG. 5) is repeated until the oil supply nozzle 10 is applied to the nozzle hook 11.
In the case of so-called preset oil supply, when the valve of the oil supply nozzle 10 is closed again (n in FIG. 5), the oil supply control device 17 outputs a close signal to the flow control valve 6 and closes the flow control valve 6 (FIG. 5). n to p), the voice generator 15 is activated, and the voice “Since refueling has been completed.

  In this case, when refueling is stopped within a certain refueling amount range while refueling is being performed at a large flow rate, refueling is performed at a low flow rate. Can be prevented from overflowing.

If the amount of fuel supply is 2 liters or more in step ST9, in other words, if 2 liters or more is already supplied at the time of the second fuel supply stop, the fuel supply control device 6 has a small free space in the fuel tank of the automobile. Therefore, it is determined that the flow rate should be reduced, and step ST13 and subsequent steps are executed.
As shown in the time chart of FIG. 9, the refueling control device 17 starts refueling at a large flow rate of 30 liters / minute, and when the refueling amount is 2 liters or less at the first refueling stop, a large amount of 30 liters / minute is obtained. If the refueling resumes at the flow rate and the refueling amount is 2 liters or more when the second refueling is stopped, refueling at a low flow rate of 15 l / min. If the refueling is stopped again, refueling at a fine flow rate of 8 l / min. Is done.

After refueling at a fine flow rate of 8 liters / minute, in normal refueling, the valve of the refueling nozzle 10 is closed (n in FIG. 5), the valve of the refueling nozzle 10 is opened (l in FIG. 5), and a predetermined timing Then, the process of closing the solenoid valve 30 and setting it to a slightly open (for example, 8 liter / min) oil supply state (m in FIG. 5) is repeated until the oil supply nozzle 10 is applied to the nozzle hook 11.
In the case of so-called preset oil supply, when the valve of the oil supply nozzle 10 is closed again (n in FIG. 5), the oil supply control device 17 outputs a close signal to the flow control valve 6 and closes the flow control valve 6 (FIG. 5). n to p), the voice generator 15 is activated, and the voice “Since refueling has been completed.

  In this way, if the oil supply is stopped within a certain range of oil supply while a large amount of oil is being supplied, if a low oil supply is executed, the oil supply after the fuel tank of the car is almost full Can prevent overflow.

  As for refueling the motorcycle, when motorcycle refueling is set from the data input device 16, the refueling control device 17 turns on the motorcycle refueling indicator 14, and the flow control valve 6 is opened small (for example, 10 liters / minute). Keep it in a possible state. Since the motorcycle is supplied with a small flow rate, it is possible to prevent the oil from overflowing even in a small fuel tank of the motorcycle.

  According to the oil supply apparatus concerning embodiment of illustration, it becomes an oil supply apparatus with high oil supply efficiency and safety, and can implement suitably as an oil supply apparatus especially for self-service.

  It should be noted that the illustrated embodiment is merely an example, and is not a description to limit the technical scope of the present invention.

In the oil supply apparatus provided with the oil supply control device (17) for displaying the oil supply amount displayed on the oil supply amount indicator (13), the oil supply control device (17) receives the ON signal of the nozzle switch (12) and receives the pump signal. The motor (4) for driving (5) is started, the flow rate control valve (6) is fully opened to supply a large amount of oil, and the liquid level sensor detects the liquid and the valve of the oil supply nozzle (10). When is closed, the stop of refueling is detected from the absence of the flow signal (ST3 Then, a close signal is output to the flow control valve (6) (ST4), and if the amount of oil supply at this time is within a certain amount (ST5), a full open signal is output to the flow control valve (6) (ST6). If the amount of lubrication is a certain amount or more during the second large amount of oil supply (ST9), the flow rate control valve (6) is opened slightly and the small amount of fuel is supplied (ST13). When the fuel supply is stopped during the execution (ST14), the flow rate control valve (6) is slightly opened to supply the fine flow amount (ST16), and the pump (5) is turned on in response to the OFF signal from the nozzle switch (12). An oil supply device having a function of stopping a motor (4) to be driven.
