Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a liquid supply installed in a gas station such as a gas station and automatically stops the liquid supply at an integer amount after the tank is almost full. Regarding the improvement of the device.

[Prior Art] Such a liquid supply device is disclosed in Japanese Patent Application No. 60-201672 (see Japanese Patent Application Laid-Open No. 62-64799 and Japanese Patent Application No. 61-216038) by the present applicant.
(See Japanese Patent Laid-Open No. 63-82998).

All of these devices are effective in that the liquid level sensor detects the liquid level when the tank is almost full and automatically stops refueling, reducing the work of the operator and improving the service to customers. It is a thing.

However, recently, competition for gasoline sales is fierce, and in order to sell full-tank refueling, it is no longer possible to catch up simply by improving services. Therefore, it is desired to make the gas station attractive by some peculiarity (for example, agitating the customer's heart).

Therefore, the applicant of the present invention has proposed a technique in Japanese Patent Application Laid-Open No. 60-183395, in which a notification is issued when the predicted refueling amount and the actual refueling amount match. However, in a so-called integer liquid supply in which the liquid supply is automatically stopped at an integer amount after it is almost full, the "full tank" value is different from the normal case, and for example, after the sensor detects the liquid level, Since the liquid is supplied, there is a case where the amount of oil supplied is not the expected amount when the sensor detects the liquid surface, or vice versa.

[Problem to be Solved by the Invention] Therefore, an object of the present invention is to reliably compare the expected liquid supply amount with the actual liquid supply amount by determining that the liquid supply is completed, that is, when the pump is stopped. Another object of the present invention is to provide a liquid supply device that can be played and has a game property.

[Means for Solving the Problems] According to the present invention, a liquid is supplied from a pump to a meter, and a controller for receiving a flow rate signal from the meter from an oscillator and displaying the signal on an indicator is provided. In a liquid supply device that automatically stops liquid supply at an integer amount later, an expected liquid supply amount setting means for setting an expected value of the liquid supply amount, and an informing means that operates by a signal from the control device, The control device, when the expected liquid supply amount is input from the estimated liquid supply amount setting means,
The expected amount of liquid supply is set, and when the amount of liquid supply and the set amount of the expected value match during the liquid supply operation, the notification means is activated, and at that time it is determined whether the pump is stopped. , Has a function of operating the notification means when it is stopped.

[Explanation of Action and Effect] Therefore, when the liquid supply amount is full before the liquid supply work and the set amount become equal during the liquid supply work and the liquid supply work is completed, no notification is given. The notification means is activated when the liquid supply amount becomes equal to the set amount during the liquid supply operation. The customer then expects a "hit". However, if the liquid supply work is not completed at that time, the pump does not stop (as is well known, the pump does not stop when the nozzle is hung on the nozzle hook), so that the notification is not given again. If the liquid supply amount becomes equal to the set amount, the liquid supply work is finished, and the pump is stopped when the nozzle is hooked on the nozzle hook. Then, the notification means gives a notification of the coincidence.

As described above, in the present invention, the notification is different depending on whether the set amount is smaller than or larger than the liquid supply amount, and it is determined that the liquid supply is completed when the pump is stopped. Therefore, the game is improved and the joyful spirit can be fueled. .

[Preferred Embodiment] In carrying out the present invention, the expected value of the liquid supply amount is set to the first decimal place, and the liquid supply amount at the time of automatic liquid supply stop is an integer second place.
It is preferable that the position be zero.

In practicing the present invention, the expected liquid supply setting means preferably comprises a ten-key pad and a display.

When the present invention is carried out, a voice generator is used as the notification means, and when the liquid supply amount becomes equal to the set value, for example, "Ping Pong" is uttered, and the liquid supply amount when the automatic liquid supply is stopped and the set amount are matched. For example, it is preferable to say "Congratulations".

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 shows a typical oil supply apparatus for carrying out the present invention. An oil supply machine S includes a pump 2 driven by a motor 1. The pump 2 sucks up oil stored in a tank (not shown) from the suction pipe 3 and sends it to the discharge pipe 4. The discharge pipe 4 is provided with a meter 5 for measuring the flow rate and a flow rate control valve 6 for controlling the flow rate, and the discharge pipe 4 is connected to a fueling nozzle 8 via a hose 7. The flow rate signal from the meter 5 is sent from the transmitter 10 to the control device 11 as a pulse signal.
Then, the control device 11 sends it to the display device 12, and the amount of oil supply is digitally displayed here, and the valve drive unit 13 is controlled by the signal from the control device 11 to turn on the flow control valve 6. It controls and controls the amount of refueling. The refueling nozzle 8 is provided with a non-contact type liquid level sensor / insertion sensor 14 for non-contact detection of the liquid level,
Further, a nozzle switch 15 for detecting that the refueling nozzle 8 has been housed in the refueling machine S, a numeric keypad 16 for predicting the refueling amount, which is a means for predicting the refueling amount, and a predicted refueling amount indicator 17,
A voice generator 18, which is a notification means, is provided. And
Sensor 14, nozzle switch 15, numeric keypad 16, display 17,
The voice generator 18 is connected to the control device 11. In addition, indicator
12 can be displayed up to the second decimal place, and the second decimal place becomes zero when refueling an integer. The expected refueling amount indicator 17 can display up to the first decimal place.

The control device 11 is composed of a microcomputer and, in addition to a clock and a well-known control circuit, an integer refueling control circuit for controlling the refueling amount to be an integer, when the expected refueling amount matches the refueling amount when the automatic refueling is stopped. In addition, a notification control circuit for notifying that a match has been made by the voice generator, a storage device for storing the number of times of refueling stop and restart, and the flow rate pattern at each restart are provided.

Next, the refueling control flow will be described with reference to FIG.

The control device 11 determines whether or not the nozzle switch 15 is turned on (step S1), and if YES, that is, when the nozzle 8 is removed from the fueling machine S, the detection signal from the sensor 14 is used. It is determined whether or not the nozzle 8 is inserted in the fuel filler port (step S2). If YES, a control signal is output to the valve drive unit 13 and the flow rate control valve 6 that has been opened is narrowed down to a low discharge (for example, 3 / min) (step S3) and a control signal is output to the motor 1. To operate the pump 2 (step S4). Next, the valve of the oil supply nozzle 8 is opened to start oil supply, and it is determined based on the pulse signal from the transmitter 10 whether or not the amount of oil supply has reached 0.2 (step S5). If YES, a control signal is output to the valve drive unit 13 to open the flow rate control valve 6 (for example, flow rate 45 / mi).
n) (step S8), when the detection signal from the liquid level sensor 14 is input during refueling (step S10), the valve drive unit 13
To output a control signal to close the flow control valve 6 (step S11). Next, it is determined whether or not a fixed time (for example, 3 seconds) until the bubbles almost disappear (step
S12), if YES, it is determined whether the liquid level is detected based on the detection signal from the sensor 14 (step S1
3). If YES, the integer refueling control circuit determines whether or not the refueling amount is an integer (step S16), and if NO, the flow rate control valve 6 is opened slightly (step S17). When the refueling amount becomes an integer (YES in step S18), the flow rate control valve 6 is closed (step S1).
9), in the case of YES in step S16, the control signal is output to the motor 1 to stop the operation of the pump 2 (step S2
0), based on a signal from the nozzle switch 15, it is determined whether or not the refueling nozzle 8 is housed in the refueling machine S (step S21). If YES, output a control signal to the valve drive unit 13 to open the flow rate control valve 6 (step S22),
End control.

The above shows the control flow in which the container is filled up by one refueling control and the refueling is completed, but if step S13 is NO, that is, the bubble disappears after 3 seconds have elapsed in step S12 and the liquid level is detected. If not, it is determined based on the signal from the sensor 14 whether the refueling nozzle 8 is inserted in the refueling port (step S14). If the refueling nozzle 8 is removed from the refueling port, that is, if NO. In step S20, the operation of the pump 2 is stopped, and if YES, the flow rate control valve 6 is slightly opened (3 / min) (step S15), the process returns to step S5, refueling is restarted, and steps S5 to S13 are repeated. . In this way, a small discharge (3 / mi
After n), the discharge becomes high. In this step S8, the flow rate is changed, for example, from the first 45 / min each time refueling is restarted.
The flow rate control valve 6 is controlled so that the flow rate is reduced to 35 / min, 20 / min, and 3 / min, and the amount of refueling is gradually reduced, so that the liquid flows out from the refueling port in a relatively short time. I try to refuel without filling up.

If step S5 is NO, that is, the amount of lubrication is 0.2
Until it reaches, it is determined by the detection signal of the sensor 14 whether or not the liquid level is detected (step S6). If YES, the process proceeds to step S11, and if NO, the fueling nozzle is detected by the detection signal of the sensor 14. It is determined whether or not 8 is inserted in the fuel filler (step S7). If NO, the process proceeds to step S11. If YES, the process returns to step S5 to continue the fueling. Further, if step S10 is NO, it is determined by the detection signal of the sensor 14 whether or not the refueling nozzle is inserted in the refueling port (step S9). If NO, the process proceeds to step S11, and if YES, the step is performed. Return to S10 to continue refueling. In this way, steps S6, S7, S9, S10, S
In S13 and S14, the liquid level is constantly detected and whether the refueling nozzle 8 is inserted in the refueling port is detected to monitor the refueling state.

Next, referring to FIG. 3, a control flow at the time of setting the estimated oil supply amount will be described.

If you enter the expected amount of lubrication until the tank is almost full using the numeric keypad 16 for setting the estimated amount of lubrication up to the first decimal place (step
S30), the control unit 11 displays the set amount of fuel according to the estimated fuel amount indicator 17
(Step S31). Then, refueling is performed according to the refueling control flow described above, and it is determined whether or not the refueling amount is equal to the set amount (step S32). S33). Then, at that time, it is determined whether the refueling is automatically stopped, that is, the operation of the pump 2 is stopped by the flow (step S34), and if YES, that is, if the refueling amount matches the expected refueling amount, the utterance is issued. For example, let's say "Congratulations. It's a hit. We will provide a free service for the refueling fee" on the device 18 (Step S3
5), end control, and if NO, that is, if refueling is not stopped, end control as it is.

[Effects of the Invention] As described above, the present invention has the following effects.

(I) Since it is an integer liquid supply, it is only necessary to match the integer value with the set value, and there is no fraction processing, so control is easy.

(Ii) Since the notification is different depending on whether the liquid supply amount is smaller or larger than the set amount, it is interesting that the customer can expect whether or not there is the first notification.

(Iii) Since the pump is stopped at the end of the liquid supply work, it is possible to prevent the operator from arbitrarily supplying the liquid.
