A large truck having a plurality of fuel tanks stops in the fueling area of the fueling device 1, removes the fueling nozzle 9a of one fueling system (for example, fueling system A) from the nozzle hook 10a, and an on signal is output from the nozzle switch 11a. When input to the fuel supply control device 15 (ST1), a fuel supply request signal is output from the fuel supply control device 15 to the fuel supply permission device 17 (ST2).

As shown in the flowchart of FIG. 4, when the fueling permission device 17 receives the fueling request signal (ST21), the fueling request lamp of the fueling permission device 17 is lit (ST22).
When a manager in the management station 16 confirms the safety of refueling and presses the refueling permission button of the refueling permission device 17 (ST23), a refueling permission signal is output to the refueling device 15 (ST24).

When the oil supply control device 15 receives an oil supply permission signal from the oil supply permission device 17 (ST3), it outputs a zero return signal to the oil supply amount indicator 12, and outputs a drive signal to the motor 4a (ST4). Thereby, the previous oil supply amount display displayed on the oil supply amount indicator 12 is returned to zero, the pump 4a is driven by the motor 4a, and the oil supply is possible.
The fuel oil is supplied from the fuel supply nozzle 9a into the fuel tank of the truck through the fuel supply pipe 3a, the pump 5a, the flow meter 7a, and the fuel supply hose 8a.

When refueling by the refueling nozzle 9a, in order to refuel to the other fuel tank, the refueling nozzle 9b of the refueling system B is removed from the nozzle hook 10b, and the nozzle switch 11b outputs an ON signal, When the nozzle switches 11a and 11b of both the systems A and B are turned on (ST5), the fuel supply control device 15 outputs a lighting signal to the summing indicator 13, and turns on the summing indicator 13.
At the same time that the total display device 13 is turned on, the fuel supply control device 15 outputs a drive signal to the motor 4b (ST6), and the pump 5b is driven by the motor 4b. Thus, as described above, fuel is supplied from the fuel nozzle 9b into the fuel tank via the fuel pipe 3b, the pump 5b, the flow meter 7b, and the fuel hose 8b.

In this way, the refueling device that is allowed to refuel can supply fuel from both refueling systems without giving any instructions, so that refueling to large trucks with multiple fuel tanks can be performed quickly and efficiently. Become.
Further, the fact that the fuel supply from both the fuel supply systems is being performed can be easily recognized by the fuel supplier by the fact that the total indicator 13 is turned on.

In this way, the oil supply amounts from both the oil supply systems A and B are added together and displayed on one oil supply amount indicator 12, so that the oil supply amount is not mistaken and the oil charge can be easily settled.

Oil supply is performed by the nozzles 9a and 9b of both the oil supply systems A and B. For example, when the oil supply of the oil supply system A ends first, the oil supply nozzle 9a is applied to the nozzle hook 10a, and an OFF signal is input from the nozzle switch 11a ( (ST7), the fuel supply control device 15 outputs a stop signal to the motor 4a (ST8), and the drive of the pump 5a is stopped.
Further, when refueling of the other refueling system B is completed and an off signal is input from the nozzle switch 11b, in other words, when the nozzle switches 11a and 11b of all the refueling systems A and B are turned off (ST9), refueling control is performed. The device 15 outputs a turn-off signal to the total display device 13 and turns off the total display device 13.
At the same time that the total display device 13 is turned off, the fuel supply control device 15 outputs a stop signal to the motor 4b (ST10), the drive of the pump 5b is stopped, and the fuel supply ends.

  The refueling control device 15 outputs a refueling data signal to the POS 18 (ST11), and the POS 18 that has received the refueling data signal issues a refueling slip and manages the processing of the refueling data.

Even when the oil supply nozzle 9b of the oil supply system B is removed prior to the oil supply nozzle 9a of the oil supply system A in step ST1 (ST12), step ST2 and subsequent steps are executed.
In this case, in step ST4, the motor 4b is driven.

  In step ST5, oil supply from both the oil supply systems A and B is completed, and only the oil supply system A is finished. When the oil supply nozzle 9a is applied to the nozzle hook 10a and the nozzle switch 11a is turned off (ST13), the oil supply control is performed. The device 15 stops the motor 4a (ST14) and executes step ST11.

  In step ST7, when refueling of the refueling system B ends first and the nozzle switch 11b is turned off first (ST15), the refueling control device 15 stops the motor 4b (ST16) and is the same as in step 9 and subsequent steps. Perform steps.

  In addition, when refueling only a desired oil supply amount, if the oil supply amount is set in advance from the data input device 14 and the oil supply is performed, the oil supply control device 15 performs the same oil supply control as described above, and supplies the oil up to the set amount. To finish refueling.

  According to the illustrated embodiment, it is possible to provide a fuel supply device that can speedily and efficiently supply a large truck or the like having a plurality of fuel tanks, and that can easily settle a fuel charge and process a slip.
