The refueling control unit 35 resets the refueling data in response to the close signal of 23 and restarts the refueling control.

Next, the refueling operation will be described. First, in a state where the refueling nozzle 14 is at the ascending position A, when the string 21a for operating the elevating switch 21 is pulled, the elevating switch 21 is closed, and a signal thereof is input to the nozzle elevating controller 31 of the controller 30 (FIG. 4). ST1). At this time, since the signal from the position sensor 15 is the ascending position A (ST2 in FIG. 4), the reel motor 13 rotates forward (ST3 in FIG. 4), and the oil supply hose 12 is pulled out from the hose reel 11. When the refueling nozzle 14 descends to the refueling position B, the position sensor 1
The signal from No. 5 becomes the refueling position B (ST4 in FIG. 4), and the reel motor 13 stops (ST5 in FIG. 4). And
The fueling is performed by inserting the fueling nozzle 14 into the fueling port of the vehicle.

On the other hand, when a signal of the refueling position B is input from the position sensor 15 to the gas sensor control unit 32 (ST in FIG. 5).
1), a pressure relief valve 9 to prevent misjudgment due to dripping
Is opened for a certain time to release the pressure in the oil supply hose 12, the air pump motor 29 rotates forward (ST2 in FIG. 5), and the vapor starts to be sucked from the opening 17 at the tip of the oil supply nozzle 14.
Then, when the sucked vapor is detected by the oil type sensor 24 and matches the oil type supplied by the oil supply device (FIG. 5 S
T3), this signal is output to the refueling pump control unit 33, and the air pump motor 29 is reversed to scavenge the oil type sensor 24 (ST4 in FIG. 5). If the oil type cannot be determined and the oil type is unknown (ST3 in FIG. 5), this signal is output to the oil supply pump control unit 33, the alarm 25 is operated, and the air pump motor 29 is rotated in reverse to detect the oil type sensor 24. (Fig. 5
ST5).

The oil supply pump control unit 33 to which the oil type matching signal is input from the gas sensor control unit 32 (ST1 in FIG. 6)
By driving the pump motor 4 (ST2 in FIG. 6), the pump 3
Starts oiling. When a signal indicating that the oil type is unknown is input (ST3 in FIG. 6), the operator confirms the oil type and presses the cancel button 26 when the signal is correct, and the closing signal is input (ST4 in FIG. 6). Alternatively, the continuous oil supply button 23 is pressed, the oil type is determined again, and the pump motor 4 is driven by the input of the oil type coincidence signal (ST5 in FIG. 6) (FIG. 6).
ST2). In addition, since the oil type is different,
When the lifting switch 21 is closed to raise the pressure (ST6 in FIG. 6), the refueling pump control unit 33 ends the control without driving the pump motor 4.

When the refueling is the preset refueling, when the preset button 22 is pressed to input a desired amount to the preset control unit 34 (ST1 in FIG. 7), the refueling amount is set (FIG. 7).
ST2).

Then, the refueling control unit 35 receiving the signal of the refueling position B from the position sensor 15 (ST1 in FIG. 8) resets the previous refueling data, and the indicators 16 and 27 are reset to zero (ST2 in FIG. 8). ). Then, as described above, when the pump 3 is driven and refueled from the refueling nozzle 14, the refueling amount is measured by the flow meter 5, and the flow rate pulse from the flow rate pulse transmitter 6 is input to the refueling control unit 35 ( Fig. 8 ST
3) It is counted and displayed on the displays 16 and 27 (FIG. 8).
ST4). When the refueling amount reaches the set amount (ST5 in FIG. 8), the control valve 7 is closed and the discharge of the oil is stopped (ST6 in FIG. 8). When refueling is completed and the string 21a is pulled to close the elevating switch 21 (ST7 in FIG. 8), the control valve 7 is opened (ST8 in FIG. 8), and the control is ended.

In order to refuel another vehicle, if the continuous refueling button 23 is pressed before the lift switch 21 is closed (FIG. 8).
ST9), the current refueling data is reset (FIG. 8)
ST2), the next refueling can be performed immediately. Also,
Refueling is completed before the refueling amount reaches the set amount (Fig. 8
ST5), when the continuous refueling button 23 is pressed (FIG. 8S
T10), ST2 and subsequent steps in FIG. 8 are executed. Further, before the refueling amount reaches the set amount (FIG. 8, ST5), the string 2
1a is pulled and the elevating switch 21 is closed (FIG. 8)
ST11), end the control.

On the other hand, when refueling is completed and the string 21a is pulled, the elevating switch 21 is closed, and the signal thereof is sent to the nozzle elevating control unit 3.
1 (ST1 in FIG. 4), the current position is the refueling position B, and since the signal from the position sensor 15 is not in the ascending position A (ST2 in FIG. 4), the reel motor 13 rotates in the reverse direction (ST6 in FIG. 4). The hose 12 is wound around a hose reel 11. When the refueling nozzle 14 moves up to the ascending position A, a signal from the position sensor 15 indicates the ascending position A.
(ST7 in FIG. 4), and the reel motor 13 stops (ST8 in FIG. 4).

When the refueling is completed and the up / down switch 21 is closed (ST6 in FIG. 5), the gas sensor control unit 32 ends the control and continuously feeds the next vehicle before the up / down switch 21 is closed. When the refueling button 23 is pressed (ST7 in FIG. 5), the gas sensor control unit 32 opens the depressurizing valve 9 for a certain period of time, rotates the air pump motor 29 forward (ST2 in FIG. 5), and determines the oil type. Refueling is performed. Further, the refueling pump control unit 33 is also provided with the elevation switch 2.
1 is closed (ST7 in FIG. 6), the pump motor 4 is stopped (ST8 in FIG. 6), the control is terminated, and the lift switch 21
If the continuous refueling button 23 is pressed before is closed (ST9 in FIG. 6), the pump motor 4 is stopped temporarily (S6 in FIG. 6).
T10) After waiting for the result of the oil type determination (ST1, S6 in FIG. 6)
T3) The pump motor 4 is controlled again.
