Based on the signal from 2, the refueling position is reached and t! , the motor 3 is stopped (step 34), a reset signal is output to the preset amount setting means 38 and the counting calculation means 39 to erase the previous refueling data, and the refueling data display 2
0 and the previous oiling data on the preset display 21 are returned to zero, and a control signal is output to turn the pump motor 14 ONL.
The control valve 19 is opened to enable refueling (step S5).
).

8 and 9 Refueling In FIG. 5, when the nozzle valve of the refueling nozzle 6 is opened to start refueling and a flow rate pulse is input from the flow rate pulse transmitter 17 (step 510), the refueling determining means 36 stores that refueling is in progress. , the counting calculation means 39 calculates the refueling amount based on the pulse signal, and displays the refueling amount on the refueling amount display meter 20a of the refueling data display 20 and the amount on the refueling amount display meter 20b (step 511). Medium judgment means 36
Step 512) determines whether or not a certain period of time T^ (for example, 1 second) has elapsed without a flow rate pulse signal based on the signal from the clock 35. If YES, it is assumed that refueling has been interrupted and refueling is in progress. (Step S)
13>, if the refueling is restarted after that and the flow rate pulse signal is input, the process returns to step S10.

Fig. 6 shows a functional block diagram of preset lubrication and integer lubrication, and Figs. 7 to 9 show the first lubrication of preset lubrication.
Figure 0 shows a control flowchart for integer oil supply.

In FIG. 6, the control device 30 includes a reset determination means 42 which outputs a signal from the preset switch 8 to the timer means 41 when the count value of the counting means 39 is zero, and a reset determination means 42 which outputs a signal from the preset switch 8 to the timer means 41 when the count value of the counting means 39 is zero, and a reset determination means 42 which outputs a signal from the preset switch 8 to the timer means 41 when the count value of the counting means 39 is zero. A clock means 41 measures the signal input time and outputs it to the preset amount setting means 38, and a preset value is obtained from a storage means 33 which stores the number of steps and preset data shown in FIG. 11 based on the signal from the timer means 41. A preset amount setting means 38 that reads and sets a numerical value from the integer amount calculation means 44 and outputs the value to the preset amount display 21, a numerical value set in the preset amount setting means 38, and a counting calculation means. 39 and outputs a valve closing signal to the control valve 19 when they match, and a preset setting means 3 based on a signal from the preset switch 8.
8 is set, and an integer calculation means that converts the signal from the integer switch 11 when there is no preset refueling memory in the storage means 34 and when the refueling determining means 36 does not remember that refueling is in progress. 44. It is comprised of an integer refueling judgment means 43 and an integer quantity calculation means 44 which calculates an integer quantity by summarizing the numerical values of the three counting calculation means based on a signal from the means 34.

C. Preset oil supply Figures 7, 8, and 9 show the control flow of preset oil supply. In FIG. 7, preset switch 8
(Step 550), count calculation means 3 is pressed before refueling.
9 is zero (step 551), the preset determining means 42 sends a signal to the clocking means 41 and the clocking means 4
1 counts the signal from the clock 35 until the preset switch 8 is released (steps S53 and 554).
).

In FIG. 8, the preset amount setting means 38 is configured such that the count value TB of the timer means 41 is initially incremented by 1 after 50 m5ec (to prevent chattering) and thereafter every 1000100O, as shown in FIG. As shown in FIG. 11, the reset data stored in the corresponding address is read from the storage means 33 for each step, and is set and displayed on the preset display 21 (step 355...
・).

Then, when the step number reaches tlO, the process starts again from tl.

Note that the lamp 21b is lit when displaying the amount, and the lamp 21c is lit when displaying the amount.

By the time the preset switch is turned on like this,
A desired preset amount can be easily set.

In FIG. 9, during refueling, the comparison means 45 always determines whether the amount of oil supplied from the counting calculation means 39 (see FIG. 3) is equal to the set value of the preset amount setting means 38 (step 560), and the answer is YES. When this happens, a valve closing signal is output to the control valve 19 to close it (step 581).

D. Integer lubrication In FIG. 10, when normal lubrication is interrupted and the integer lubrication switch 9 is pressed (step 530), the integer lubrication judgment means 4
3, it is determined whether or not preset lubrication is stored in the storage means 34 (step $31); in this case, it is normal lubrication (if greset lubrication is stored, it is ignored). Next, it is determined whether or not refueling is stored in the refueling determining means 36 (step 532). In this case, since refueling has been interrupted, the information during refueling is not stored, and next, the integer amount calculation means 44 determines whether integer refueling has already been performed with the amount (step 533) or whether integer refueling has not been performed with the amount. A determination is made (step 535). At this stage, it is the first integer refueling, so the amount at the time of interruption will be, for example, 3.
If it is 363 yen and the lower digit is less than 70 yen, round it up to 100 yen and get 3,400 yen. For example, if it is 3,383 yen and 70 yen or more, round it up to 200 yen and convert it into an integer to 3,500 yen, and calculate the scheduled stoppage refueling amount. is set in the preset amount setting means 38 and displayed on the preset amount display 21 (step 53
7) When performing integer lubrication by quantity, when the integer switch 11 is pressed again (step 538), the integer quantity calculation means 44 calculates the lubrication quantity at the time of interruption as 28.034, for example, with one decimal place less than 7. In the case of grooves, round up to 112 and make it 29 (l,
28.836, if one decimal place is 0.7 g or more, round up to 2 g and convert it to an integer as 3072, set the scheduled stop amount in the preset amount setting means 38, and display it on the preset amount display meter 21. (Step 540), and each time the integer switch 9 is pressed in this way (Step S41.
538), an amount integer and an amount integer are set and displayed alternately.

If you restart refueling after setting, it will be refueling (step 3).
3G, 542), when the set amount is reached, the valve is closed according to the flow shown in FIG. 9, and refueling is stopped.

In addition, when integer refueling is performed and further refueling is possible, when the integer switch 9 is pressed again, the integer amount operator stage 44 goes through steps S30 to 332 and determines whether or not the amount was previously set as an integer. If the answer is YES, the next calculation is performed to convert the reverberation into an integer, and the amount is set in the preset amount setting means 38 and displayed on the preset J1 display 21 (step 534), and if the answer is No, the amount is set as an integer. Therefore, step 335 is YES, and step S
In step 36, the quantity is converted into an integer and displayed on the preset display 21.

E. Continuous refueling Figures 13 and 14 show continuous refueling, that is, the refueling amount is 71. This figure shows a functional block diagram and a control flowchart when refueling the next customer.

In FIG. 13, when the control device 30 receives a signal from the reset switch 10 when the refueling determining means 36 does not store that refueling is in progress, it outputs a stop signal to the pump motor 14 and controls the control valve 1. A valve closing signal is output to the clock means 41, and a signal is output to the clock means 41. Resetability determination means 40;
The signal from the clock 35 is timed by the signal from the means 40, and after a certain period of time, a drive signal is sent to the pump motor 14.
A clock means 41 is provided for outputting a valve opening signal to the control valve 19 and a reset signal to the preset amount setting means 38 and the counting means 39.

In FIG. 14, when refueling is finished and the reset switch 10 is pressed to refuel the next customer (step 520)
In this case, since refueling is not in progress, the refueling determining means 36 has no memory of refueling (step 521), so the reset possibility determining means 40 outputs a control signal to control the pump motor 14.
0FFL, close the control valve 19 (step 522),
Next, the timer 41 determines whether a certain period of time (for example, 1 second) has elapsed based on the signal from the clock 35 (step 5).
23) When the time elapses, a control signal is output and the pump motor 1
4 is turned ON, the control valve 19 is opened, the previous refueling data of the preset amount setting means 38 and the counting calculation means 39 are erased, and the refueling data display 20 and the preset amount display 2 are
The previous refueling data of 1 is returned to zero, and refueling becomes possible (
Step S24>.

F. The nozzle rises from the refueling value WL to the ascending position i1H In Fig. 4, when refueling is finished and the lift switch 11 is pressed (step S1), in this case it is not in the ascending position (step S2), and since refueling is not in progress, refueling is stopped. Since refueling is not stored in the intermediate determination means 36 (step S6), the control signal from the lift determination means 37 is stopped and the pump motor 1
4 to 0FFL, and the control valve 19 is closed (step S7).

Next, a reverse rotation signal is output to the hose reel motor 3 to reverse the rotation and raise the refueling nozzle 6 (step S8), and when a signal indicating the raised position H is input from the nozzle position detector 12 (step S9), the motor 3 is stopped. . Note that even if the lift switch 11 is pressed by mistake during refueling, it is ignored (step S6).

[Summary] As explained above, according to the present invention, by simply pressing and holding the preset switch, the preset amount is automatically incremented depending on the time the switch is pressed, and the desired preset amount is set, thereby allowing the preset amount setting means to work. performance and operability can be improved.
