To explain the overall structure of the kerosene delivery vehicle, in order to deliver kerosene, there is an oil storage tank 2 made of metal such as an aluminum alloy on the loading platform Ia of the truck 1, and a fuel supply device connected to this oil storage tank 2 through an oil distribution pipe. 3 will be installed.

In the oil supply device 3, a hose reel 3 is provided inside the outer case 4.
The rotating shaft of this hose reel is connected to a forward/reverse rotation motor 5 via a one-way clutch 31, and a refueling hose 7 having a refueling nozzle 6 attached to the tip thereof is retractably wound around the hose reel. The base end of the oil supply hose 7 is connected to an oil supply pipe 8 connected to the oil storage tank 2. and,
A refueling pump 9 driven by the forward/reverse rotating motor 5 and a flow meter 10 are disposed in the refueling pipe 8, and a flow rate pulse transmitter 11 is attached to the flow meter 10.

In the figure, 12 is a control device composed of 10 circuits, etc.; 13
14 is a car battery. The exterior case 4 also has a power switch 15 and a fuel switch 16.
, and an alarm 17 that notifies you when the voltage of the battery 14 falls below a certain value.

As shown in the block circuit diagram of FIG. 2, the control device 12 receives output signals from a power switch 15, a refueling switch 16, a battery 14, and a flow rate pulse transmitter ll, and outputs signals from an annunciator 17, a motor 5, and a refueling amount display meter. A power supply means 18 connected to the battery 14 supplies power to the control device 12 in response to the output of the power switch 15, and outputs a conventionally known voltage connected to the battery 14. The measured value of the voltage measuring means 19 using a meter etc. is
It was introduced into the overdischarge notification means 2o.

The over-discharge notification means 20 stores and sets a voltage (for example, IOV) slightly lower than the standard voltage (for example, 12V) of the battery 14 as a reference value. When the measured value from the voltage measuring means 19 becomes lower than the value of the a means 21, an activation signal is output to the alarm driving means 22, and the motor controlling means 23
Outputs a low-speed rotation signal to Note that this output is reset by the off signal of the refueling switch 16.

The alarm drive means 22 receives the signal from the overdischarge alarm means 20 and operates an alarm that generates light or sound.

The motor control means 23 receives an ON signal from the refueling switch 16 to control the motor 5 to rotate at high speed, and receives a signal from the overdischarge warning means 20 to control the motor 5 to rotate at a low speed.

The counting means 24 counts the pulse signals from the flow rate pulse transmitter 11 and displays the amount of oil supplied on the oil amount display meter 13 via the oil amount display meter driving means 25. Then, the refueling switch 1
Upon receiving the ON signal of 6, the count value is reset.

Next, to explain the usage and operation with reference to the flowcharts in Figures 3 and 4, kerosene is supplied from the underground tank to the oil storage tank 2 at the gas station, the truck I leaves the gas station, and stops at the customer's place. .

At this time, leave the automatic JH engine switch in the idling state before turning it off. To refuel, pull out the refueling nozzle 6 and refueling hose 7 and turn on the power switch 15 (Step I in Figure 3), and the output signal from this will enter the power supply means 18, which will , supplies battery power to the control device 12, and the control device 12 becomes movable.

When the power switch 15 is turned on in this way,
The voltage of the battery 14 is measured by the voltage measuring means 19, and the voltage value is input to the overdischarge informing means 20.

Here, it is compared with a reference value (for example, 10) stored and q in the storage means 21, and when the input voltage value falls below this reference value, the alarm drive means 22 (step opening) in FIG. The alarm 17 is activated by the action of the means 22, and the voltage of the battery 14 is abnormally reduced due to light or sound, and as a result, the motor 5 may stop, or the amount of refueling may be incorrectly counted or displayed. inform you that there is a risk of

At the same time, the overdischarge notification means 20 also outputs a signal to the motor control means 23 (Stenopfah). This signal output is stopped (step 2) when the refueling switch 16 is turned off (step 2). This battery voltage test is performed until the power switch 15 is turned off (to step).

When the refueling switch 16 is turned on (steel knob in Fig. 4), the on signal enters the counting means 24 as a reset signal, the previous refueling amount is returned to zero, and the refueling amount indicator 13 is returned to zero (step port ). Further, if the ON signal is input to the motor control means 23 and the over-discharge alarm signal is not input (step port), the motor 5 starts rotating at high speed with the output from this and the oil supply pump 9 is driven (step no). Note that at this time, the hose reel does not rotate due to the action of the one-way clutch.

Insert the tip of the refueling nozzle 6 into the refueling port of a plastic tank, etc.
When the nozzle 6 is opened by operating a lever, kerosene is sucked up from the oil storage tank 2 and discharged from the end of the nozzle 6. At that time, the flow rate is measured by the flowmeter 10, and the meter III value is sent to the counting means 2 as a flow rate signal from the flow rate pulse generator 11.
4, and the oil amount is displayed on the oil amount display meter 13.

During refueling, it is always checked whether an over-discharge alarm signal is input, and when the signal is input to the motor control means 23 (step port), the motor control means 23 reduces the rotation speed of the motor 5 and switches it to low speed rotation. Te (stemple)
, to reduce the power consumption of the pantry 14.

In this way, refueling is continued with the motor 5 rotating at a low speed, and when the desired amount of refueling is completed, the refueling switch 16 is turned off (step port), and the motor 5 and the refueling pump 9 are stopped. is completed. Next, when the hose winding switch is turned on, the motor 5 rotates in reverse, the hose reel rotates, and the drawn-out refueling hose 7 and refueling nozzle 6 are housed in the winding case 4.

Once the hose has been wound in this manner, the motor 5 is stopped and the rotation of the hose reel is also stopped by turning off the above-mentioned unwinding switch.

Finally, the power switch 15 is turned off to complete all operations.

In the above embodiment, the rotation speed of the motor 5 is lowered as a means to cope with an abnormal drop in the voltage of the battery 14 during refueling. A means may be provided in advance, and when the voltage of the battery 14 decreases, a signal may be output to the idling amplifier means to increase the idling speed, increase the amount of power generation, and increase the voltage of the battery 14.

The idling-up means include using an existing choke or stepping on the accelerator.
