Further, a motor 11 that rotates forward and backward is provided, the pump 5 is directly connected to the motor 11, the hose reel 8 is connected via a one-way clutch 12 and a slip clutch 13, and a detector 14 that measures the rotation amount of the hose reel 8 is provided. For example, the rotary encoder is a hose reel 8
It is provided in.

The control box 2 is provided in the housing 3.
The control box 20 is provided with a refueling amount indicator 21 and a keyboard 22. The keyboard 22 has a power switch 22a and a refueling switch 22b.
And a take-up switch 22c. And
The control device 23 provided in the control box 20 receives a flow pulse signal from the pulse transmitter 6a of the flow meter 6, a rotation pulse signal from the detector 14, and an open / close signal from each switch of the keyboard 22. The drive signal from the controller 23 is sent to the motor 11 and the display signal is sent to the refueling amount indicator 21.
Has been entered. Electric power of the battery 24 of the truck 1 is supplied to each device described above.

Next, the operation will be described with reference to the flowchart of FIG. When the oil delivery vehicle arrives at the customer's house, when the power switch 22a of the keyboard 22 is turned on (ST1), each device is in a drivable state (ST2), the fuel supply switch 22b is closed and a fuel supply signal is input to the control device 23 ( ST3),
Controller 23 outputs a normal rotation signal to motor 11 (ST
4), the motor 11 rotates forward and the pump 5 is driven. At this time, the rotation of the motor 11 attempts to rotate the hose reel 8 in the direction in which the oil supply hose 7 is pulled out, but since the hose reel 8 is connected to the motor 11 via the slip clutch 13 and the one-way clutch 12, The lease 8 does not rotate spontaneously.

When the oil supply hose 7 is pulled by holding the oil supply nozzle 9, the oil supply hose 7 is pulled out from the hose reel 8, and a pulse signal from the detector 14 is transmitted to the control device 23 as the hose reel 8 rotates (ST5). The pulse signal is calculated as the withdrawal amount (A) of the refueling hose 7 (ST
6). When the refueling nozzle 9 is inserted into the refueling tank and the valve is opened, the kerosene in the oil storage tank 2 receives the pump 5, the flow meter 6,
The fuel is discharged from the fueling nozzle 9 into the fueling tank through the fueling hose 7. The flow rate pulses from the pulse transmitter 6a of the flow meter 6 are counted by the control device 23 and displayed on the refueling amount indicator 21.

When the refueling is completed, return to the oil delivery vehicle with the refueling nozzle 9, close the take-up switch 22C and input a take-up signal to the control device 23 (ST7). A high speed rotation signal of reverse rotation is output to 11 (ST8), and the hose reel 8 winds up the oil supply hose 7 at high speed. At this time, the worker guides the refueling hose 7 by hand so that the refueling hose 7 is wound around the hose reel 8 in an orderly manner. Then, a pulse signal from the detector 14 is transmitted to the control device 23 with the rotation of the hose reel 8 (ST9), and the pulse signal is calculated as a winding amount (B) of the refueling hose 7 (ST10). When the difference between the amount of pull-out (A) and the amount of winding (B) is (X), for example, 3 meters (ST11), the controller 23 outputs a low-speed rotation signal of reverse rotation to the motor 11 (ST11). ST12), the hose reel 8 rotates at a low speed. As a result, the operation immediately before the winding of the refueling hose 7 is completed can be performed safely.

When the refueling hose 7 is almost wound,
Open the take-up switch 22c and send a stop signal to the control unit 23.
(ST13), the control device 23
(ST14), and the hose reel 8 stops. Then, the refueling nozzle 9 is put on the nozzle hook 10, the power switch 22a is opened (ST1), and all refueling operations are completed.

In the embodiment described above, the amount of winding of the oil supply hose is calculated, the amount of withdrawal is compared with the amount of winding, and when the difference becomes a fixed amount, a low-speed rotation signal is output to the motor. The winding amount may be directly subtracted from the amount, and a low-speed rotation signal may be output to the motor when the value becomes a constant amount.

If the oil supply hose 7 gets stuck on something during winding, the slip clutch 13 slips and the rotation of the hose reel 8 stops, so that the safety of the oil supply hose 7 at the time of winding is ensured.
