Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fluid supply device that automatically stops fluid supply after supplying a predetermined amount of fluid by inputting a preliminary fluid supply stop signal by pressing an integer switch after fluid supply is interrupted. .

[Prior art] The oil supply amount is set to an integer value (for example, 112.0.512 or 0°2
In a refueling device that performs integer refueling (the value at the end of a multiple of Q, or a value in increments of 100 yen or 200 yen), after detecting the liquid level and interrupting refueling, press the integer switch to reserve the refueling stop. The system inputs a signal, presets the scheduled stoppage amount, restarts refueling, and automatically stops refueling when the predetermined amount of refueling reaches the planned stoppage amount.

In such a refueling device, conventionally, there are two switch boxes installed near the refueling nozzle, one for quantity integer and one for gold a integer.
Two integer switches were provided, and the customer could press one of these switches according to his wishes.

However, space is limited near the refueling nozzle, and 2
Providing multiple switches increases the size of the switch box.
In addition, the switch may be pressed incorrectly, which requires a means to correct this, which is undesirable.

OBJECTS OF THE INVENTION Accordingly, an object of the present invention is to provide an oil supply device in which the area around the integer switch is made compact.

[Structure of the Invention] According to the present invention, in a liquid supply device that automatically stops liquid supply after supplying a predetermined amount of liquid by inputting a liquid supply stop preliminary signal by pressing an integer switch after interrupting liquid supply, A display device is provided that alternately displays the amount or amount at which liquid supply will be stopped.

[Invention Effects] Accordingly, in response to the press of one integer switch, the amount of liquid to be supplied that is scheduled to be stopped is alternately displayed in quantity or amount, and the integer switch is rotated.
In other words, the switch box can be made more compact, and the conventional method of pressing the two integer switches incorrectly and the means for correcting the incorrect pressing can be eliminated.

The preset display 21 displays the preset amount as a quantity or a monetary amount when the preset switch 8 is not pressed to preset the amount of refueling, and also displays an integer when refueling is resumed after the refueling nozzle 6 detects the liquid level and refueling is interrupted. When the switch 9 is pressed, a preset amount display meter 21a displays the scheduled stoppage fueling amount, which is an integer value of the fueling amount at the time of interruption, as 1 or a monetary amount, and lamps 21b and 21c indicate whether the displayed value is a quantity or a monetary amount.

The reset switch 10 is pressed to return the display on the display 20, 21 to zero when refueling the next customer, before pressing the lift switch 11 to return the refueling nozzle 6 to the raised position H after refueling. The pump motor 14 is turned on.

In Figure 2, the control wave! Reference numeral 30 is composed of a microcomputer, and is provided with a central processing unit (CPU) 31. Signals from each of the above-mentioned devices are input to the central processing unit 31 via an input/output device (Ilo>32).

In FIG. 3, the control device 30 includes a flow rate pulse transmitter 1.
Refueling determining means 36 for determining whether refueling is in progress based on the pulse signal from 7 and the clock signal from clock 35.
Then, the function is stopped by the refueling signal from the refueling determining means 36, and a forward/reverse signal is output to the hose reel motor 3 based on the signal from the lift switch 11 and the position detection signal from the nozzle position detector 12, and the pump motor is 14, an opening/closing signal to the control valve 19, and a lift determining means 3i which outputs a reset signal to the preset amount setting means 38 and the counting calculation means 39, and a preset amount display set by the means described later. outputs a display signal to the refueling data display device 21, counts and calculates the pulse signal from the preset amount setting means 38, which is reset by a signal from the lift determining means 37, and the flow rate pulse transmitter 17, and outputs a display signal to the refueling data display device. It also includes a counting calculation means 39 which is reset by a signal from the elevation determination means 37.

A. Refueling level from rising level WH! Lowering the nozzle to L In FIG. 4, when the lift switch 11 is pressed at the raised position H for refueling, the lift determining means 37 of the control device 30 determines that the lift switch 11 has been turned on.In step S1), the nozzle position detector Based on the signal from 12, the refueling nozzle 6
is at the raised position H (Step S2), outputs a normal rotation signal to the hose reel motor 3, rotates it in the normal direction, and lowers the refueling nozzle 6 (Step 53).
When the refueling amount reaches rIIL based on the signal from 2, the motor 3 is stopped (step S4), a reset signal is output to the preset amount setting means 38 and the counting means 3-9, and the previous refueling data is erased. The previous lubrication data on the lubrication data display 20 and preset display 21 is returned to zero, and a control signal is output to turn the pump motor 14 ON.
, the control valve 19 is opened to become ready for refueling (step $
5) In step S2, if it is not in the raised position, the refueling determining means 36 determines whether or not refueling is in progress (step S6); if refueling is in progress (YES), the work ends. If refueling is not in progress (NO), pump motor 14
is stopped and the control valve 19 is closed (step 57).Then, the hose reel motor 3 is reversed (step S8), and this operation continues until the nozzle 5 reaches the ascending position 11fH (step 59). I get kicked.

B. Normal 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), and then displays the refueling amount on the refueling amount display meter 20b (step 511). Judgment means 36
In step 312), it is determined based on the signal from the clock 35 whether a certain period of time T^ (for example, 1 second) has elapsed without a flow rate pulse signal, and if it is yB3, it is assumed that refueling has been interrupted and refueling is in progress. The memory is erased (step 513); however, if refueling is resumed and a flow rate pulse signal is input thereafter, 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 flilJ control flowchart for integer lubrication.

In FIG. 6, the control device 30 includes a preset judgment means 42 which outputs a signal from the preset switch 8 to the timer means 41 when the count value of the three counting means is zero, and a preset judgment means 42 which outputs a signal from the preset switch 8 to the timer means 41 based on a signal from a clock 35. A clocking means 41 measures the signal input time and outputs it to the preset amount setting means 38, and a preset value is read from a storage means 33 storing the step number and preset data shown in FIG. 11 based on the signal from the clocking means 41. a preset amount setting means 38 that sets or 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; Comparison means 45 outputs a valve closing signal to the control valve 19 when they match, and the Puzoset setting means 3 receives 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 composed 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 counting calculation means 39 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
When you press (step 550), the counting calculation means 3 is activated before refueling.
If the count value of 9 is zero (step 351), 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 (step S53.354).
).

In FIG. 8, the preset amount setting means 38 increments the count value TB of the timer means 41 by one every 1000100O, for example, at first after 50m5ec (to prevent chattering), as shown in FIG. As shown in FIG. 11, the preset 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 S55...
・).

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 religious means 45 always judges whether or not the refueling Jl (see FIG. 3) from the counting calculation means 39 is equal to the set value of the preset amount setting means 38 (step 360), YES. When this happens, a valve closing signal is output to the control valve 19 to close it (step 5et).

D. Integer lubrication In FIG. 10, when normal lubrication is interrupted and the integer lubrication switch 9 is pressed (step 330), the u number lubrication determination means 4
3, it is determined whether or not preset lubrication is stored in the storage means 34 (step 531); in this case, it is normal lubrication (if preset lubrication is stored, it is ignored), and 0th order lubrication is in progress. It is determined whether or not refueling is being stored in the determination means 36 (step S32>, in this case, refueling has been interrupted, so refueling is not stored, and the next (integer quantity calculation means 44 has already been stored). It is determined whether integer refueling was performed based on the amount (step 533) or whether integer refueling was performed based on the amount (step 535).Since this is the first integer refueling at this stage, the amount at the time of interruption is, for example, 3363 yen. If the lower digit is less than 70 yen, round it up to 100 yen and make it 3,400 yen.For example, if it is 3,383 yen or more, round it up to 200 yen and convert it to 3,500 yen, and preset the scheduled stoppage refueling amount. It is set in the amount setting means 38 and displayed on the preset amount display 21 (Step 3
37), when performing integer lubrication by quantity, when the integer switch 11 is pressed again (step 538), the integer quantity calculation means 44 calculates that the lubrication quantity at the time of interruption is, for example, 28.0312, with one decimal place less than 7. In the case of 112, it is rounded up to 2SII, and when the decimal place is 0.712 or more, such as 28.836, it is rounded up to 2g and converted into an integer as 3012, and the scheduled stop amount is determined by the preset amount setting means 38. is set and displayed on the preset amount display meter 21 (step 540).

In this way, each time the integer switch 9 is pressed (step S
41.938), the amount integer and the X integer are set and displayed alternately. If refueling is resumed after the setting, refueling is in progress (steps 339 and 542), and when the set amount is reached, the valve is closed according to the flow shown in FIG. 9, and refueling is stopped.

Further, when integer refueling is performed and further refueling is possible, when the integer switch 9 is pressed again, the integer amount calculating means 44 passes through steps 330 to 332 to determine whether or not the amount was previously set as an integer. If YES, then perform the next calculation to convert the amount into an integer, set it in the preset amount setting means 38, and display it on the preset amount display 21 (Step 534), if No, the amount was set as an integer. Therefore, step 335 becomes YES, and step 33
In step 6, the quantity is converted into an integer and displayed on the preset display 21.

[Summary] As is not explained above, according to the present invention, each time an integer switch is pressed, the scheduled stoppage amount of refueling is displayed on the preset amount display in the amount or amount, and the switch box is made smaller by using only one integer switch. can do. Furthermore, it is possible to eliminate the conventional pressing of two integer switches in a wrong manner and the means for correcting the wrong pressing.
