DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the illustrated embodiments. FIG. 1 is a diagram showing a system configuration of the present invention. In FIG.
, An oil storage tank 4, an oil supply device 5, and a hose reel 6 are mounted.

[0007] Reference numeral 20 in the figure denotes a refueling pump 26 described later.
The hose is wound by a hose reel 6 driven by a hose reel motor. An oil supply nozzle 21 for discharging fuel oil to a tank 22 is connected to a tip of the hose.

Reference numeral 23 in the figure denotes a slave unit, which is for displaying the amount of refueling and instructing start and stop of refueling at a position distant from the vehicle 1, and 30 is a refueling device. , And reference numeral 32 indicates a switch box.

FIG. 2 shows an embodiment of the above-described oil supply device 5, in which an oil supply pump 26 driven by a pump motor 25 which operates by receiving electric power from a battery 40 of the vehicle, and a pump 26 , A flow rate pulse transmitter 28 that converts the measurement result of the flow meter 27 into a flow rate pulse, and winds up a hose that is fed by receiving power from a battery 40 of the vehicle. Hose reel 6, pump motor 25, hose reel motor 2
9 and also converts the flow rate pulse from the flow rate pulse transmitter 28 into a lubricating amount and outputs it to the display 30. Further, the pump motor 25, the hose reel Turn on motor 29
A control means 31 for turning off is provided.

Reference numeral 32 denotes a switch box provided at a position where the refueling device 5 can be easily operated. The switch box 32 includes a power switch 33 for supplying and stopping power to the refueling device 5 and a refueling switch 34 for operating and stopping the pump motor 25. And a winding switch 35 for operating and stopping the hose reel motor 29
And are arranged.

FIG. 3 shows an embodiment of the control means 31 described above. In FIG.
The judging means uses the electric power from the vehicle battery 40 via a pump motor drive stop judging means 38 and a hose reel motor drive stop judging means 39 to be described later.
The power supply is supplied to the hose reel motor 29. The power supply switch 33 is turned on and off by pressing the power switch 33, and the operating states of the pump motor 25 and the hose reel motor 29 are determined. When it is determined that the power switch 33 is not operated, the power is continuously supplied regardless of the pressing of the switch 33.

Numeral 38 denotes a pump motor drive stop judging means which is turned on / off by a signal from a refueling switch 34 and is turned on by pressing a power switch 33 and a winding switch 35 when the refueling pump motor 25 is operating. Also turns off the pump motor 25 that is being driven.

Numeral 39 denotes a hose reel motor drive stop judging means, which is turned ON-OF by a signal from the winding switch 35.
In addition, when the power supply switch 33 or the refueling switch 34 is pressed while the hose reel motor 29 is operating, the operating hose reel motor 29 is stopped.

Numeral 40 denotes a counting means which returns to zero when the refueling switch 34 is pressed, and when the refueling is started and a flow rate pulse is output from the flow rate pulse transmitter 28, this pulse is integrated. This is output to the display 30 as the refueling amount.

Next, the operation of the apparatus thus constructed will be described with reference to FIG.
A description will be given based on the flowchart shown in FIG. When the power switch 33 is pressed (step a), the control means 3
1 becomes operable (step b). In this state, the judging means 37, 38, and 39 are operated by the refueling switch 34, the winding switch 35,
And monitoring the pressing of the power switch 33 (step
C, l, g).

In this state, when the refueling switch 34 is pressed, the counting means 40 returns the display 30 to zero to clear the previous refueling amount, and the pump motor drive stop determining means 3
8 operates the pump motor 25 (step d).
In this state, when the fueling nozzle 21 is inserted into the tank 22 and the fueling lever is pulled up, fuel is discharged from the nozzle 21,
Refueling is performed.

During the refueling period, the control means 31 monitors the state of the refueling switch 34, the winding switch 35, and the power switch 33 (steps E, F, G), and any one of the switches is pressed during refueling. In this case, the pump motor 25 is turned off and the refueling operation is stopped irrespective of the type of switch pressed (step).

With the refueling stopped, take-up switch 35
Is pressed (step リ), the hose reel motor drive stop determination means 38 drives the hose reel motor 29 to wind the drawn hose 20 around the reel 6 (step ヌ). During this winding operation, the hose reel motor drive stop determination means 38 determines whether the oil supply switch 34,
The state of the take-up switch 35 and the power switch 33 is monitored (step, o, w), and the hose reel motor 29 is monitored.
If any one of the switches 33, 34, 35 is pressed during the operation of, the hose reel motor 29 is stopped regardless of the type of the pressed switch to stop the winding operation of the hose (step E). Pump motor 2
When the power switch 33 is pressed while the motor 5 and the hose reel motor 29 are stopped (step Y), the function of the control means 31 stops (step ST).

It should be noted that even when the power switch 33 is pressed while the pump motor 25 or the hose reel motor 29 is operating, the power ON-OFF determining means 37
This switch operation is invalidated, and the operation of the control means 31 is continued to prevent the control operation from being inadvertently stopped.

[0020]

As described above, according to the present invention, the pipe connected to the oil storage tank is provided with a pump driven by a pump motor, a flow meter interposed, and a hose having a refueling nozzle attached to a tip thereof. A refueling mechanism, a hose reel driven by a hose reel motor for winding a hose, a power switch for activating the refueling mechanism, a refueling switch for starting a pump motor, and a winding switch for starting a hose reel motor are provided. Since the switch board and the hose reel motor stop determining means for determining that any switch of the switch board is pressed while the hose reel motor is operating, and stopping the hose reel motor, Stopping the hose reel motor by simply pressing any one without selecting a switch It can be, it is possible to quickly deal with the emergency situation when intake hose wound after refueling the end.
