Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a refueling device installed at a refueling station for refueling automobiles and the like with gasoline.

[Conventional technology]

Among such refueling devices, there is a suspended type refueling device in which a refueling mechanism such as a refueling pump and a refueling motor is housed in a machine room, a refueling hose storage device is suspended from a canopy, and the refueling hose is fed out from the hose storage device. In this system, a display device that displays the amount of refueling, etc. is separately attached to a location that is easily visible from the refueling point, for example, on the wall of a building such as an office.

This display is relatively large so that the displayed numbers can be read correctly even from a refueling point far from the installation location. On the other hand, for refueling, in addition to full tank refueling, there is also preset refueling that presets the refueling amount, so this preset amount also needs to be displayed, and the preset amount is displayed separately from the conventional display that displays the refueling amount. The display is placed side by side with the fuel supply display.

[Problem that the invention seeks to solve]

Therefore, at least two indicators are required for one refueling device, and it is difficult to install these in a limited space such as the wall of a building. Furthermore, compared to so-called full-tank refueling, preset refueling was performed less frequently (and the preset amount indicator was not used very effectively).

Furthermore, since a small display is sufficient for a ground-fixed refueling system, a dot display is used so that the display area can be freely selected.

However, there is a limit to the size of one dot display,
For this reason, the size of the display itself is limited, and it has been difficult to use display means using dots in large displays.

The purpose of the present invention is to solve the above-mentioned disadvantages of the conventional example, to make it possible to effectively utilize the display itself and the space by combining the display devices into 1-), and to easily make large display devices using dots. The objective is to provide a refueling device that can be manufactured to

[Means for solving problems]

In order to achieve the above object, the gist of the present invention is to provide a display device in which a plurality of dot display bodies are arranged in series.

[Effect]

According to the present invention, when only the refueling amount is displayed, one large number is displayed on each dot display, and when both the preset amount and the refueling amount are displayed at the time of preset refueling, , the preset amount and the refueling amount are displayed together on the same display with smaller numbers indicating only the refueling amount.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is an explanatory diagram showing an embodiment of the oil supply system of the present invention. First, the overall structure of the oil supply system will be explained. This is a suspended type oil supply system, and the oil supply system is connected to an underground oil storage tank (not shown). A pipe 1 is set up in a machine room 2 on the ground, and a refueling pump 4 connected to a refueling motor 3 and a flow meter 6 connected to a flow rate pulse transmitter 5 are sequentially installed to the refueling pipe 1. 1 was further raised and guided downward from the upper canopy. On the other hand, a refueling hose storage device 8 is suspended from the canopy, and a hose reel 11 connected to a hose reel motor 9 and a hose payout length detection means 10 is stored in the refueling hose storage device 8. A refueling hose 13 having a refueling nozzle 12 at its tip was wound around the refueling hose 13, and the other end of the refueling hose 13 was connected to the refueling pipe 1.

In the figure, 14 indicates a lift switch provided on the fuel supply hose 13 near the fuel nozzle 12, and 15 indicates a preset switch.

In addition, a display device 17 is attached to a wall surface 16 of a building or the like in a gas station, and a control device 18 using a microcomputer or the like is installed at an appropriate location such as inside the building to control the raising and lowering of the fuel hose 13 and the display on the display device 17. installed.

The display 17 is, for example, a dot-type display 17a.

Four pieces 17b, 17c, and 17d are arranged in series in the horizontal direction to form one display.

As shown in the block diagram of FIG. 2, the control device 18 includes an input/output device (Ilo) 19 and a central processing unit (C
PU) 20, storage device (RAM) 21, storage device (RO
M) 22 and a clock circuit 23, and the ascending and descending positions of the refueling hose 13 are set in storage devices 21 and 22.

Then, the output signals from the flow rate pulse transmitter 5, the hose delivery length detection means 10, the lift switch 14, and the preset switch 15 are introduced into the control device 18, and the control signals from the control device 18 are transmitted to the refueling motor 3 and the display 17. , was introduced into the hose reel motor 9.

Next, the method of use and operation will be explained according to the flowchart of FIG. 3. When not refueling, the refueling hose 13 is raised and the refueling nozzle 12 is located above, which is the standby position.

To refuel, press the up/down switch 14 (Step 1), and an on signal from this enters the control device 18. The control device 18 determines that the refueling nozzle 12 is now in the upper position, and based on this, and is output to the hose reel motor 9. As a result, the hose reel motor 9 rotates forward (
(step opening), the hose reel 11 rotates normally, the refueling hose 13 is paid out, and the refueling nozzle 12 is lowered. On this occasion,
The length of the refueling hose 13 is detected by the hose reel length detecting means 10 connected to the hose reel 11, and this detection signal is sent to the control device 18, where the refueling nozzle 12 is fed to the lower end, which is the refueling position. When it is determined that the fuel supply motor 3 has been turned on (step), the control device 18 outputs an output to the display 17 to return the display to zero, and also outputs to the drive circuit of the refueling motor 3 to turn it on (step).

To preset the amount of oil to be supplied, press the preset switch 15 next (snap-off), a preset signal will be input to the control device 18, and the control device 18 will operate the fourth
As shown in the figure, the display form of the display 17 becomes a reduced display (go to step), and the preset amount display 24 shows the preset amount, for example, 30J, in small letters straddling the display bodies 17a and 17b, such as r P 30L J. will be displayed.

When refueling is performed by inserting the refueling nozzle 12 into the gasoline tank of the automobile in this manner, the flow rate of the gasoline pumped up from the underground storage tank by the refueling pump 4 is measured by the flowmeter 6, and the flow rate is pulsed by the flow rate pulse transmitter 5. It is input as a signal to the control device 18 (stepped), counted here and displayed as the amount of refueling on the display 17 (sterapuri)
. This refueling amount display 25 is reduced to a size that fits within the remaining space below the preset amount display 24,
For example, when displaying r28.56J as the refueling amount, the last digit number "6" is displayed across the display bodies 17c and 17d.

When the refueling amount reaches the preset i (stellar preset), it is output to the refueling motor 3 by the action of the control device 18, and the refueling motor 3
and the oil supply pump 4 automatically stops (step). Next, when the lift switch 14 is pressed (Stella Pull), the hose reel motor 9 is reversed (Stella Pull), and as a result, the hose reel 11 is reversed, the refueling hose 13 is wound up, and the refueling nozzle 12 is at the upper end in the standby position. It rises again to (stenbuwa).

The above is a case of preset refueling, but next we will explain the case of full refueling without presetting the refueling amount.The refueling hose 13 is lowered, the indicator 17 returns to zero, and the refueling motor 3 and refueling After turning on the pump 4 (step oil 2), if the refueling nozzle 12 is inserted into the gasoline tank of the automobile without pressing the fresh switch 15 to start refueling, the control device 18 will show the display 17. , each display body 178 to 17d by enlarging the number 26 indicating the amount of refueling.
(step force).

As a result, the refueling amount, for example r2B, is counted (stepped) based on the pulse signal from the flow rate pulse transmitter 5.
, 56J, as shown in FIG.
"2" r8J with the number 26 enlarged one by one in 7d
r5J r6J is displayed (Stellapuri).

In this way, refueling is not performed), and when the tank is full, by pressing the lift switch 14 (step YO), the refueling motor 3
and the oil supply pump 4 stop (step), the hose reel motor 9 reverses (step), and the hose reel 11
is reversed, which causes the refueling hose 13 to connect to the hose reel 1.
1 and the refueling nozzle 12 is located at the upper end (sterapuri).

As mentioned above, when performing preset lubrication, the displayed numbers are reduced and the preset amount display 24 and the lubrication amount display 2 are
5 are written side by side in two rows in one display 17, but the rate at which brisk refueling is performed is lower than that at full refueling (and when the pre-throttle amount is reached, the refueling motor is automatically turned off). 3 is stopped, no major inconvenience occurs even if the preset amount is displayed in small characters.

〔Effect of the invention〕

As described above, since the refueling device of the present invention has a plurality of dot display bodies arranged in series, it is possible to easily form a large display device as a whole even if the dots are used. Since it is possible to display numbers indicating the amount of refueling, etc. across the display, the displayed numbers can be scaled up or down. For example, the preset amount and the amount of refueling can be displayed together on one display. This makes it possible to effectively utilize the space itself and space.
