Reference numeral 30 denotes the above-mentioned hand switch, which is mounted near the nozzle 8 of the oil supply hose 5 as shown in FIG. 4, and provided with a number of switches capable of selecting the functions of the oil supply device. ing. That is, a nozzle provided with an integer refueling function and a preset refueling function is provided with a nozzle elevating switch 31, a reset switch 32, an integer refueling switch 33, and a preset refueling switch 34 (a in the same drawing), and only normal lubrication is possible. In such a case, a nozzle elevating switch 31 and a reset switch 32 are provided (b in the figure). These switches 31, 32, 33,
34 is a cable 3 provided along the refueling hose 5.
5 is connected to the nozzle elevation control means 18 and the control panel 20. In addition, the code | symbol 36 in a figure shows the cable which connects the hand-held indicator 10 and the control panel 20.

Next, in the device configured as described above, 3
The operation of registering and updating basic data using one switch will be described with reference to the flowchart shown in FIG. (Basic data registration mode) When the refueling device is newly installed or when the basic data needs to be changed, the changeover switch 24 provided on the control panel 20 is operated to select the registration operation. .

In this state, when the nozzle up / down switch 31 of the hand switch 30 is pressed (step A), the nozzle up / down control means 18 rotates the hose reel motor 7 forward to lower the refueling nozzle 8. When the nozzle 8 is pulled out to a position where it can be refueled (step c), a signal is output from the nozzle position detecting means 9.
8 stops the hose reel motor 7 (step
D).

In this case, since the registration mode is selected by the changeover switch 24 (step E), the registration data control means 23 stores the machine number data, oil type data, and unit price registered in the storage means 22. Basic data such as data is read out and sequentially output to the local display 10.

When data is stored in the storage means 22, as shown in FIG. 6, the item number item "1" 41, the oil type item "2" 42, and the unit price item "3" 43 These are sequentially displayed on the hand display 10 (step f). Then, the least significant digit 41a of the displayed first item "1" 41 blinks and is displayed as a numerical value that can be registered or updated (step).

In this state, the preset refueling switch 34
Each time is pressed once (step e), 1 is added to the displayed numerical value, in this embodiment "1" (step w), and when it becomes "9", "0" is displayed again. When the input of the numerical value of the least significant digit 41a is completed in this way, when the integer refueling switch 33 is pressed (step
Re), because in this case it is not the highest digit (step
Nu), the blinking position shifts to the second digit 41b of the item "1" (step, g). When the preset refueling switch 34 is pressed in this state (step e), 1 is added to the currently displayed numerical value "0" as described above.

By repeating such an operation, the most significant digit 41d
When the correction proceeds (step nu), the second and third items 42 and 43 still remain (step f), so the second item "2" 42 is displayed and the first digit 42a flashes. (Step Yo, G).

In this state, every time the preset refueling switch 34 is pressed (step o), 1 is added to the numerical value "1" of the first digit 42a displayed in a blinking state (step w), and the integer refueling switch 33 Each time you press, the digit shifts up (step n),
Le).

To partially correct a specific digit without correcting all the digits of the item "2" 42, press the reset switch 32 before the blinking position reaches the highest digit (step). , In this case, the third item “3” 4
Since 3 remains (step f), the next item, that is, the third item "3" 43 is displayed, and the first digit 43a of blinks (step y).

When the correction of the last item 43 is completed, when the reset switch 32 is pressed (step
H) Since all three items have been corrected (step f), the process exits the registration loop and waits for pressing of the elevating switch 31 (step ta). The basic data thus input is registered and updated in the storage unit 22.

When the up / down switch 31 is pressed (step), the nozzle up / down control means 18 drives the hose reel motor 7 to take up the hose 5. When the nozzle 8 reaches the upper limit position (step S), a signal is output from the nozzle position detecting means 9 and the hose reel motor 7 stops (step S2). And the changeover switch 24
Is switched from the registration operation to the refueling operation.

(Refueling Mode) When the elevation switch 31 of the hand switch 30 is pressed (step b), the refueling control means 21 reads out the machine number data, the oil type data, and the unit price data from the storage means 22 and sends them to the POS 26. Output. The POS 26 outputs a refueling permission signal to the control panel 20 when these data are input. As a result, the nozzle elevation control means 18 rotates the hose reel motor 7 forward (step b). When the refueling nozzle 8 reaches the refueling position, a signal is output from the nozzle position detecting means 9 (step c), so that the nozzle elevating control means 18 stops the hose reel motor 7 (step d) and sets the nozzle 8 Stop at the refuelable position and execute the refueling control operation (step n).

That is, when the refueling lever is pulled without operating any of the hand switches 30, normal manual refueling is executed, and after the refueling is stopped, the integer refueling switch 3 is turned on.
When 3 is pressed, additional refueling is executed until the current refueling amount becomes a sharp numerical value.

Further, when the refueling is performed after the preset refueling switch 34 is pressed, the stop valve 13 is closed and the refueling is stopped when the preset refueling amount is reached.

During the refueling in this way,
A flow pulse is output from the flow pulse transmitter 16. The flow rate pulse is output to the refueling control means 21 via the refueling control means 17, is displayed as a refueling amount on the refueling amount indicator 27 and the hand-held indicator 10 installed at easy-to-see positions, and is also output to the POS 26. You.

When refueling is completed and the nozzle up / down switch 31 of the hand switch 30 is pressed, the nozzle up / down control means 18 reverses the hose reel motor 7 to wind up the hose 5 and raise the nozzle 8. The POS 26 is generated by a signal generated by pressing the nozzle lift switch 31.
Performs data processing based on the refueling amount and unit price data, and issues a refueling slip.

When refueling is performed continuously without raising the nozzle 8, the reset switch 32
By pressing, a new refueling becomes possible while a refueling slip is issued based on the previous refueling amount.

In the above-described embodiment, the case where the basic data is registered and updated using three switches has been described. However, even if two of the four switches, for example, the reset switch 32 and the integer refueling switch 33 are used. Basic data can be registered and updated. This operation will be described with reference to the flowchart shown in FIG.

That is, when the basic data is registered, the registering operation is selected by the changeover switch 24. In this state, when the nozzle up / down switch 31 of the hand switch 30 is pressed (step a), the nozzle up / down control means 18 is pressed.
Turns the hose reel motor 7 forward to lower the nozzle 8. When the nozzle 8 is pulled out to the refuelable position (step c), a signal is output from the nozzle position detecting means 9, so that the nozzle elevation control means 18 stops the hose reel motor 7 (step d).

In this case, since the registration mode is selected (step E), the registration data control means 23 reads out the basic data registered in the storage means 22 and sequentially outputs the basic data to the local display 10.

The unit number item "1" 41, the oil type item "2" 42, and the unit price item "3" stored in the storage means 22.
43 are sequentially displayed on the hand display 10 (step
F). Then, the least significant digit 41a of the displayed first item "1" 41 is displayed in a blinking state (step).

In this state, every time the integer refueling switch 33 is pressed once (step), 1 is added to the displayed numerical value "1" (41a) (step e),
When "9" is reached, "0" is displayed again. When the input of the numerical value of the least significant digit 41a is completed in this way, when the reset switch 33 is pressed (step), the blinking position is the second digit because it is not the most significant digit in this case (step). Shift to column 41b (step nu,
G). When the integer refueling switch 33 is pressed in this state (step 1), 1 is added to the currently displayed numerical value "0" in the same manner as described above (step 3).

By repeating such an operation, the most significant digit 41d
When the correction has been made (step re), the second and third items 42 and 43 still remain (step w), so the second item 42 is displayed, and the first digit 42a blinks (step w). F)

In this state, every time the integer refueling switch 33 is pressed (step), 1 is added to the displayed numerical value (step o), and each time the reset switch 32 is pressed (digit), the digit is increased. Shift up (step ri, nu).

When the reset switch 32 is depressed in a state where the highest digit is reached by the digit shift by the reset switch 32 (steps S and R), the third item "3" 43 still remains in this case. Therefore, the next item, the third item "3" 43, is displayed, and the least significant digit 43a blinks. When the modification of the last item “3” 43 is completed (step w), the process exits the registration mode.

When the up / down switch 31 is pressed (step y), the nozzle up / down control means 18 drives the hose reel motor 7 in the reverse direction (step) to wind up the hose 5. When the nozzle 8 reaches the upper limit position (step S), a signal is output from the nozzle position detecting means 9 and the hose reel motor 7 stops (step S). Then, when the operation is switched to the refueling operation by the changeover switch 24, the refueling operation and data processing are thereafter performed based on the new basic data.

FIG. 8 shows an embodiment in which the present invention uses a fueling device provided with only the nozzle elevating switch 31 and the reset switch 32 as shown in FIG. 4 (b), or only two of the four hand switches. 9 is a flowchart showing an embodiment in the case of registration.

When registering basic data, the control panel 20
The registration operation is selected by the changeover switch 24. In this state, when the nozzle up / down switch 31 of the hand switch 30 is pressed (step a), the nozzle up / down control means 18 is pressed.
Rotates the hose reel motor 7 forward (step
B) Lower the nozzle 8. When the refueling hose 5 is pulled out to the position where the nozzle 8 can be refueled (step c), a signal is output from the nozzle position detecting means 9, so that the nozzle elevation control means 18 stops the hose reel motor 7 (step d).

In this case, since the registration operation is selected by the changeover switch 24 (step E), the registration control means 23 reads out the basic data registered in the storage means 22 and sequentially reads the basic data on the local display 10. Output.

The unit number item "1" 41, the oil type item "2" 42, and the unit price item "3" stored in the storage means 22.
43 are sequentially displayed on the hand display 10 (step
F). Then, the least significant digit 41a of the displayed first item "1" 41 is displayed in a blinking state (step).

In this state, every time the reset switch 32 is pressed once (step), 1 is added to the numerical value "1" of the blinking digit 41a (step e),
When "9" is reached, "0" is displayed again. When the numerical input of the least significant digit 41a is completed in this way, when the nozzle up / down switch 32 is pressed (step t), the blinking position is not the highest digit (step t) in this case, and the blinking position is the second digit. Shift to the second digit 41b (step nu).
When the reset switch 32 is pressed in this state (step), 1 is added to the currently displayed numerical value “0” (step 前述) as described above.

By repeating such an operation, the most significant digit 41e
When the correction has progressed (step re), since the second and third items 42 and 43 still remain (step w), the second item "2" 42 is displayed and the first digit 42a thereof flashes. (Step).

In this state, every time the reset switch 32 is pressed (step), 1 is added to the displayed value (step o), and each time the elevating switch 31 is pressed (step h), the digit blinks. Shifts to a higher position (step, nu).

When the reset switch 32 is depressed at the stage where the highest digit is reached by the digit shift by the elevation switch 31 (step, re), the third item "3" 43 is still in this case. Remains (step w), the third item "3" 43 is displayed, and the least significant digit 43a blinks. And the last item "3" 43
When the correction in step is completed (step w), the process exits the registration mode.

When the up / down switch 31 is pressed (step y), the nozzle up / down control means 18 reversely rotates the hose reel motor 7 (step) and winds up the hose 5. When the nozzle 8 reaches the upper limit position (step
D), a signal is output from the nozzle position detecting means 9 and the hose reel motor 7 stops (step S). And
When the operation is switched from the registration operation to the refueling operation by the changeover switch 24, data processing is thereafter executed based on the new basic data.

In the above-described embodiment, the digit shift is shifted from the lower digit to the upper digit. However, it is apparent that the same effect can be obtained by shifting the digit from the upper digit to the lower digit. .
