Description

TECHNICAL FIELD The present invention relates to an oil supply device installed in an oil supply station for supplying gasoline to an automobile or the like.

[Conventional technology]

This refueling device is provided with an indicator to display a number such as a refueling amount at the time of refueling. As refueling data, the refueling amount and the gasoline unit price are displayed in addition to the refueling amount.

In this case, conventionally, three types of items, that is, the amount of refueling, the amount of refueling, and the unit price, are arranged side by side and displayed as numbers of the same size.

[Problems to be solved by the invention]

In this way, multiple items are displayed in the same size numerical display, so the numbers of the displayed items are the amount of money,
It is difficult to judge at a glance whether to display the amount or unit price.For example, the refueling amount or refueling amount that is of particular interest to refueling customers is displayed in the same size as the unit price that is another display item. Therefore, it was not possible to distinguish these refueling data from others at a glance.

Therefore, conventionally, for example, as disclosed in Japanese Utility Model Application Laid-Open No. 55-12238, there is a display device for enlarging and displaying highly-required information by changing the layout of the display. There is an inconvenience that it is difficult to see at what position was displayed.

An object of the present invention is to eliminate the disadvantages of the conventional example and to display three types of items such as a refueling amount, a refueling amount, and a unit price on a display unit, for example, a refueling amount and a refueling amount, which are of great interest to refueling customers. In regard to the above, it is necessary to provide a refueling device that displays this in a large size in distinction from other display items, and that allows you to see at a glance what information was displayed on which display without changing the layout of the display. is there.

[Means for solving problems]

In order to achieve the above object, the present invention provides a flow meter connected to a motor with a fuel pump connected to a motor and a flow rate pulse transmitter in the case of a fuel dispenser, and connects the fuel pump and the flow meter with a fuel pipe, Connect a refueling hose having a refueling nozzle to the tip of the refueling machine, provide a nozzle hook and an indicator on the refueling machine case, receive a nozzle removal signal from a nozzle switch provided on the nozzle hook, and reset the display on the indicator to zero. A control device that outputs a start signal to the motor, receives a flow rate signal from the flow rate pulse transmitter, calculates a refueling amount and a refueling amount, and displays the calculated value together with a unit price on the display device via a display drive means. In the refueling device provided with, the display is provided with one large display part in the central part, two small display parts adjacent to the display part, and one of the small display parts.
One is a display unit dedicated to the unit price display, the other two are the refueling amount and the refueling amount changeover display unit, and a changeover switch for outputting a display changeover signal to the display drive means is provided in the refueling machine case. It is a gist that the control device is provided with a function of making the switching signal from the switching switch valid only while the nozzle application signal from the nozzle switch is being input.

[Action]

According to the present invention, among the three numerical display portions for respectively displaying the refueling amount, the refueling amount, and the unit price, for example, only the refueling amount or the numerical display of the refueling amount is formed larger than the other two. Since the amount of refueling or the display of the amount of refueling becomes more conspicuous than the other two display units, the refueling amount can be seen first and the refueling data of interest can be easily distinguished, and this can be known at a glance.

Moreover, since the layout of the display unit itself is not changed, for example, even if the display position of the numerical display of the refueling amount is changed, there is no confusion. Further, since the display position is switched only when the fuel is not refueled, there is no possibility of switching during refueling and confusing the refueling amount with the refueling amount.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view of an indicator, which is a main part of a fueling device of the present invention, and FIG. 2 is a vertical sectional front view of the fueling device. First, the overall structure of the fueling device will be described. 1
An oil supply pipe 2 that communicates with another lower tank (not shown) is set up inside, and an oil supply pump 4 connected to the oil supply motor 2 is connected to the oil supply pipe 2.
And a flow meter 6 to which a flow rate pulse transmitter 5 is connected are sequentially arranged. The end of the oil supply pipe 2 is led out of the oil supply case 1 and connected to an oil supply hose 8 having an oil supply nozzle 7 at the tip. There is. A nozzle hook 9 is formed on a side portion of the refueling machine case 1, a nozzle switch 10 that interlocks with the unfastening of the refueling nozzle 7 is provided there, and a display 11 is provided on the front surface of the refueling machine case 1.

As shown in FIG. 1 as an example, this indicator 11 displays three display items of refueling amount, refueling amount, and unit price by using seven segments, reversing plate, etc., and a numerical display portion of each item. 12,13,14 are formed as separate ones in the upper and lower three stages, and one of these three number display units 12,13,14, for example, only the middle number display unit 13 is displayed as the other two number display units. Part 12,1
Formed one size larger than 4.

And the large number display section 13 in the middle row is for displaying the refueling amount, and the small number display sections 12 and 14 in the upper and lower sections are for displaying the refueling amount and unit price, respectively, on the right side of each display section 12, 13, 14 respectively. Characters "\", "L", and "\ / L" are written as unit indications 15, 16 and 17.

By the way, the item displayed on the large number display section 13 in the middle row is not limited to the refueling amount as described above, and it is also possible to set this as the refueling amount according to the needs of each refueling station. Place 18 at an appropriate place on the case 1 of the lubricator.

In this way, the control device 19 using a conventionally well-known microcomputer or the like is housed in the refueling machine case 1, and as shown in the block diagram of FIG. The nozzle application signal when the nozzle switch 10 is turned off and the output signal from the AND circuit 20 in the control device 19 are introduced into the display drive means 21. The display driving means 21 has a function of switching the display content of a specific numeral display section according to the output from the changeover switch 18.

Further, the nozzle removal signal when the nozzle switch 10 is turned on and the flow rate pulse signal from the flow rate pulse transmitter 5 are introduced into the counting means 22, and the counting signal from the counting means 22, the nozzle removal signal and the unit price storage The output signal from the means 23 is introduced into the calculating means 24. Then, the output signals from the counting means 22, the calculating means 24, and the unit price storage means 23 are introduced into the display device driving means 21, respectively, and the output signals from these are supplied to the display device.
Introduced in 11. Further, the nozzle application signal of the nozzle switch 10 and the nozzle removal signal are introduced into the drive circuit 3a of the oil supply motor 3.

Next, the operation will be described. Prior to refueling, that is, in the state where the refueling nozzle 7 is in contact with the nozzle hook 9 and the nozzle hooking signal is being output, the amount of oil refueling is first displayed on the number display section 13 in the middle stage of the display 11. Whether to display the amount of oil supply is selected in advance, and one of them is selected by the changeover switch 18.

Then, if the changeover switch 18 is operated so as to display the refueling amount on the middle-number display unit 13, the refueling amount is set to be displayed on the number display unit 13 by the output from the indicator driving means 21, When the refueling nozzle 7 is removed from the nozzle hook 9, the nozzle switch 10 is turned on, the nozzle disengagement signal enters the counting means 22 and the computing means 24 as a reset signal, the previous refueling amount is erased, and the numerical display portions 12, 13 are reset to zero. The unit price is displayed on the number display unit 14 by the output from the unit price storage means 23, and at the same time, the refueling motor 3 is turned on by the nozzle removal signal.

Next, when the refueling nozzle 7 is inserted into the gasoline tank of the automobile to refuel, gasoline is pumped up from the underground tank by the refueling pump 4, and the flow rate is output from the flow rate pulse transmitter 5 to the counting means 22 as a flow rate pulse signal. Then, it is measured here and displayed as a refueling amount on the large numerical display portion 13 in the middle stage.

Further, regarding the amount of refueling, the counting means 22 and the unit price storage means
The refueling amount is calculated by the calculating means 24 based on the output from 23, and is displayed on the upper numeric display portion 12 by the output from this.

When the tank is filled with oil in this way and the tank is full, if the oil supply nozzle 7 is returned to the nozzle hook 9, the nozzle switch 10 is turned off and the nozzle hook signal enters the drive circuit 3a of the oil refueling motor 3. Stop and stop refueling.

By the way, in order to display the refueling amount on the large numerical display section 13 in the middle stage, if the changeover switch 18 is operated in the non-refueling state, the display unit driving means 21 causes the number display section 13 to display the refueling amount from the refueling amount display section. The number display section 12 is switched from the refueling amount display section to the refueling amount display section. In this case, the unit displays 15 and 16 on the right side of the number display units 12 and 13 are rewritten.

In the above embodiment, the refueling amount, refueling amount, and unit price numerical display portion 12
This is the case when each of
The embodiment 11 is not limited to this, and as another example, a horizontally long dot type display 11 'may be used as shown in FIG. In this case, the display 11 'is replaced by the three numeral display units 1
For example, the unit price, refueling amount, and refueling amount are displayed as 4 ′, 13 ′, 12 ′ from the left side, and “YEN / LITER” and “LITER” are displayed below the respective number display units 14 ′, 13 ′, 12 ′. "YE
Note the unit display 17 ', 16', 15 'such as "N".

Then, as in the case of the above-described embodiment, only one of the numbers displayed on the numerical display portions 13 ', 12' of the amount of fuel and the amount of fuel supplied is displayed slightly larger than the other displays.

Now, in the example shown in the figure, the number display section for the amount of fuel that is located in the center
The number displayed on 13 'is larger than the number displayed on the unit price display 14' and the refueling amount display 12 ', but displayed on the refueling amount display 12' If you want to increase only the number or to display the refueling amount numerically in the center, operate the changeover switch 18 and the display will be cut off by the function of the indicator drive means 21 (this also includes the changeover means as described above). Replace

〔The invention's effect〕

As described above, when the refueling device of the present invention displays three types of items of refueling amount, refueling amount, and unit price side by side on one display, only important refueling data such as refueling amount or refueling amount is displayed. Is displayed as a number that is slightly larger than the display of other display items, so the display of the amount or amount of refueling is more conspicuous than the other displays, and the number can be known at a glance at first It is very easy to see and easy to use. Moreover, since the layout of the display unit itself is not changed, for example, even if the display position of the numerical display of the refueling amount is changed, there is no confusion, and the display position is switched during refueling when the refueling nozzle is removed. Therefore, there is no possibility that the display position is switched during refueling and the amount of refueling and the amount of refueling are confused.
