Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Industrial Application Field 1 The present invention relates to a refueling device installed at a refueling station such as a gas station.

[Prior art] When refueling a car, etc., there are cases where a fixed value of 8 is determined in advance, such as rl, 01, "20g", etc. There are many cases.

In such a case, a refueling device is known in which a refueling nozzle is provided with a liquid level detection sensor that detects the level of the supplied liquid, such as gasoline, to automatically perform "full tank" refueling.

On the other hand, in order to improve customer service, there are also known refueling devices in which the refueling nozzle is equipped with an information reading sensor that reads customer information such as the customer number, vehicle number, and oil type, which is installed near the refueling port (e.g. , see Japanese Patent Application Laid-Open No. 60-228295).

However, a refueling device in which a refueling nozzle is provided with both a liquid level detection sensor and an information reading sensor has not been provided.

[Object of the Invention] Accordingly, an object of the present invention is to provide a refueling device having a small and easy-to-operate refueling nozzle by providing the refueling nozzle with a sensor that performs both liquid level detection and information reading.

[Structure of the Invention] According to the present invention, a sensor that serves both of liquid level detection and information reading is provided in the refueling nozzle.

[Operations and Effects of the Invention] Therefore, by providing a refueling device in which a refueling nozzle is equipped with a sensor that both detects the liquid level and reads information, it is possible to automatically perform "full tank" refueling and improve customer service. can do.

[Preferred Embodiment] When carrying out the present invention, a bar code recording customer information such as a customer number, vehicle number, and oil type is provided near the fuel filler opening of a car, and a sensor is equipped with a light emitter (e.g., a light emitting diode) and a light receiver. The light emitter is turned on and the barcode is read when the light receiver is receiving light, and the light emitter is blinked and the refueling nozzle refuels when the light emitter is turned off and the light receiver is not receiving light. It is preferable to provide a control device that determines that the liquid is inserted into the mouth and determines that the liquid level is detected when the light receiving body receives light when the light emitter is turned on.

[Example] The present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an example of an oil supply device embodying the present invention. The oil supply device 1 includes a pump 3 driven by a motor 2.
The pump 3 has a suction pipe 4 and a discharge pipe 5 connected to an oil storage tank (not shown). This discharge piping 5 is provided with an Rm meter 6 and a valve 7, further connected to this discharge piping 5 is a bowse 8, and to the hose 8 is connected a refueling nozzle 9. A sensor 10tfi is provided at the tip of the nozzle 9 for both liquid level detection and information reading.

The refueling device 1 also includes a nozzle switch 12 that detects when the refueling nozzle 9 is removed from the refueling device 1, a display gauge 18 that digitally displays the amount of refueling, and an alarm 13 that notifies abnormalities such as a difference in oil level. is provided.

The flow meter 6 is provided with a flow pulse transmitter 14 that converts the flow rate into a pulse signal, and a sensor 10. Nozzle switch 12

30, and a boss (POS) 21 installed in the office R of the gas station is connected to the control device 30.

On the other hand, near the fuel filler port 22 of the car C, there is a bar code 23 on which customer information such as a customer number, vehicle number, and oil type is recorded.
is provided.

In FIG. 2, a sensor 10 includes a light emitter (for example, a light emitting diode) 10a and a light receiver (for example, a phototransistor) 1.
The light emitting body 10a is equipped with
The photoreceptor 10b is connected to the IwJ device 30, and the photoreceptor 10b is
m device ff30.

In FIG. 3, the t, +i control device 30 includes a refueling 1 calculation means 31, an information reading means 32, an information storage means 33, and a refueling III'Ia means 34.

The refueling avi calculating means 31 zeroes the previous refueling amount by 9i based on the ON signal of the nozzle switch 12, and outputs the flow rate pulse generator 1.
The amount of oil to be supplied is calculated based on the pulse signal No. 4 and displayed on the display 18.

The information reading means 32 outputs a signal to the sensor drive unit 10c to turn on the light emitting body 10a, and reads the bar code 23 of the car C by having the light receiving body 10b receive reflected light from the bar code 23 in which customer information is written. It looks like this.

The information storage means 33 stores the customer information read by the information reading means 32.

The refueling v control means 34 connects the light emitter 1 to the sensor drive unit 10c.
0a blinks, and when the light emitter 10a is turned off, the light receiver 10b
When no light is received, that is, when the refueling nozzle 9 is inserted into the refueling port 22, which is dark due to the entry of outside light, it is determined that the refueling nozzle has been inserted, and when the light emitter 10a is turned on, the refueling nozzle 9 is inserted into the refueling port 22.
In other words, when light is received from the light emitter 10a, the light from the light emitter 10a is reflected by the liquid surface that has risen to the vicinity and is reflected by the light receiver 10b.
When the input is entered, it is determined that the liquid level has been detected and the refueling is controlled.

Next, the present invention will be explained in detail mainly with reference to FIG.

The refueling nozzle 9 is removed from the refueling device 1 and the nozzle switch 1 is turned off.
When an ON signal is input from 2 to the control device 30 (step S1), the oil supply section erases the previous oil supply amount stored in the means 31 based on this ON signal, and the display on the display 18 returns to zero. The information reading means 32 is the sensor driving section 10c.
control (Zi number is output to turn on the light emitter 10a and make the barcode 23 readable (step S2>).

When the staff member scans the barcode 23 with the tip of the refueling nozzle 9 and the customer information signal is input to the IJ control 1fiff30 (step S3), the information reading means 32G reads the barcode from the light receiving state of the photoreceptor 10b. 23 customer information is read and stored in the information storage means 33 (step S4). Next, the information reading means 32 determines whether the read oil type matches the oil type of the oil supply amount M1 (step 5).

If NO, the information reading means 32 outputs a control signal to the alarm drive unit 20 to activate the alarm 313 to notify the staff of the abnormality, and the control ends at step S6.

In the case of YES, the oil supply υ control means 34 is in a controlled state,
Sensor drive unit 10c1. :flllt! The light emitter 10a is made to blink by outputting the l signal (step 87). Next, the refueling 'alWA means 34 switches the refueling nozzle 9 to the refueling port 22 if no light is received by the photoreceptor 10b when the light emitter 10a is turned off.
If it is determined that the refueling nozzle 9 is inserted into the refueling port, it is determined whether or not the refueling nozzle 9 is inserted into the refueling port (step S8). If it is determined that the refueling nozzle 9 is inserted, a control signal is output to the motor drive unit 19. The pump 3 is activated, a control signal is output to the valve drive unit 15 to listen to the valve 7 (step S9), and oil supply is started.

The refueling J calculation means 31 outputs refueling ω based on the pulse signal from the flow G pulse transmitter 14, outputs the refueling 8 signal to the display drive unit 17, and displays the refueling amount on the display 18. .

During refueling, the refueling gil + control means 34 determines that the liquid level has been detected if light is reflected on the liquid surface and received by the photoreceptor 10b when the light emitter 10a is turned on. If no, that is, if the liquid level is not detected, the refueling al control means 34 controls whether the refueling nozzle 9 is in the refueling port or not when the light receiving element 1ob does not receive light when the light emitter 10a is turned off. Step 811) If YES, that is, if the refueling nozzle 9 is inserted into the refueling port 22, the refueling nozzle 9 is inserted into the refueling port 22.
l, IJ control means 34 determines whether or not the nozzle switch 12 is turned on (step 512), YES
In this case, that is, when the refueling nozzle 9 is removed, the process returns to step S9. In this way, during refueling, step S9
→510→sii→312→S9 refueling cycle 70-
Repeat.

If the liquid level is detected during the refueling cycle 70-, that is, if step S10 is YES, the refueling t, lJ control means 34 outputs a control signal to the valve drive unit 15 to engage the valve 7 and drive the motor. Output a control signal to # section 19 to stop the operation of pump 3 (step 573), nozzle switch 12
Check to see if is ONL/ (step 514);
Return to step 810. If what the sensor 10 detects is foam, and the foam disappears after 2 or 3 seconds, for example, the liquid level is no longer detected, step SIO becomes No, the flow returns to the refueling recycle flow, and refueling continues. Ru.

If the liquid level is still detected after 2 or 3 seconds have passed, the staff member confirms that refueling is complete, closes the valve of the refueling nozzle 9, and handles the oil from the refueling port 22. When the liquid level is reached, the liquid level is no longer detected (step 510), and the number of people is no longer detected (step 511). As a result, the oil supply control means 34 outputs a signal to the valve drive unit 15 and motor drive unit 19, and the valve rll and motor are stopped (
Step 513). Next, when the refueling nozzle 9 is applied and the nozzle switch 12 is turned off (step 514), the refueling data and customer information stored in the information storage section 33 are sent to the boss 21 for data processing (step 816).
, end control. Also, during refueling, the refueling nozzle 9 is connected to the refueling port 22.
If the refueling nozzle 9 is re-inserted into the refueling port 22, step S11 becomes No and the cycle flow becomes steps 311→813→814→S10→811, but if the refueling nozzle 9 is reinserted into the refueling port 22, step S11 becomes YES. The system then returns to the refueling cycle flow and continues refueling. Also step 8
12, when the nozzle switch 12 is OFF,
When the valve 7 is turned 11, the motor 2 stops (step $15), and the boss processes the oil supply data (step 816).
).

Although this embodiment has been described with respect to a refueling device 1 that refuels one oil ladder, in a refueling device that can refuel by blending multiple types of oil, the blend ratio may be written on the barcode containing customer information. This allows you to automatically set the blend ratio.

"Summary" As explained above, according to the present invention, a refueling device is provided in which the refueling nozzle is equipped with a sensor that serves both for detecting the liquid level and reading information, thereby automatically refueling to "full tank" without making a mistake in the type of oil. You can go fishing and improve customer service.
