Description

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

[Conventional technology and its problems]

There are two types of such refueling systems: one is a fixed type in which the refueling machine is installed on an island fixed on the ground, and the other is a suspended type in which the refueling hose is suspended from a canopy. Although the refueling location is clearly visible because it is installed vertically, it obstructs the movement of cars, and in the latter case, the refueling location is not clear, but there is no refueling machine case erected on the ground, so the site can be used more widely. Each has advantages and disadvantages.

An object of the present invention is to eliminate the disadvantages of the conventional example, install a fixed type refueling device on the ground and a suspended type refueling device, reduce the number of refueling devices installed on the ground, and make effective use of the site. In addition, the refueling position of the suspended refueling system is clearly indicated on the island of the ground-fixed refueling system, and the strengths of both refueling systems are utilized to compensate for their weaknesses. To provide a refueling device capable of displaying information at an easily visible position near a refueling point, making the entire device compact, and making effective use of space within a refueling station.

[Means for solving problems]

In order to achieve the above object, the present invention suspends a refueling hose having a refueling nozzle at its tip above the refueling position, and displays the amount of oil discharged from the refueling nozzle on a refueling machine case fixed on an island. The gist of this is that it is equipped with a display.

[Effect]

According to the present invention, the refueling area of the suspended refueling system is fixed on the ground and is clearly indicated, making it easy to understand the refueling position.
In addition, the amount of refueling performed using the refueling hose hanging from above is displayed on the display attached to the refueling machine case fixed on the island, so the amount of refueling is displayed near the refueling position. It is easy to see.

〔Example〕

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

Fig. 1 is a perspective view showing an embodiment of the oil supply device of the present invention;
The figure is a longitudinal sectional front view of the same as above, and FIG. A hose reel 3 is housed, and a refueling hose 5b having a refueling nozzle 4b at the tip is wound around the hose reel 3, and a hose reel motor 6 and a hose position detector 7 are connected. A rise switch 8 and a fall switch 9 are provided.

On the other hand, in the above-ground fixed type refueling system, a refueling pipe 13a that opens to an underground tank (not shown) is set up in the refueling machine case 12 that is installed upright on the island 11, as is conventionally known. A refueling pump 14a and a flow meter tSa are sequentially arranged on the way, and a pump motor 16a is installed on the refueling pump L4a, and a flow rate pulse transmitter 17a is installed on the flow meter L5a.
The refueling pipe 13a is led out of the case 12, and a refueling hose 5a having a refueling nozzle 4a at the tip thereof is connected to the refueling pipe 13a. In the figure, 18 is a nozzle switch that is linked to the engagement and disconnection of the refueling nozzle 4a, 19 is a refueling amount indicator, and 20a is a switch that turns on the pump motor 16a.
This is a control device that controls things like turning off and displaying the amount of refueling.

In the present invention, the refueling mechanism of the suspended refueling system is disposed within the refueling machine case 12 of the ground-fixed refueling system configured as described above, and the refueling pipe 13b is provided as in the ground-fixed refueling system. A fuel supply pump 14b and a flow meter 15b are sequentially arranged in the middle of this fuel supply pipe 13b which opens into an underground tank,
A pump motor 16b and a flow rate pulse transmitter 17b were connected to the oil supply pump 14b and flow meter 15b, respectively.

The other end of the refueling pipe 13b is led out of the refueling machine case 12 and connected to the refueling hose 5b housed inside the storage case 2.

In addition, a display 21 for displaying the amount of refueling of the suspended refueling device and other information is mounted on the upper part of the case 12.
A return switch 22 is provided separately from the display 21 for displaying the refueling amount displayed here on the display 21. In addition, 20b in the figure is the refueling hose 5 of the suspended type refueling device.
23 indicates the main switch of the suspended type and fixed type lubrication system, which is installed in an office 24 etc. in the gas station. I'll keep it.

In this way, the hose storage device 1 of the suspended refueling system is suspended from the canopy 10, and on the other hand, the refueling machine case 12 of the ground-fixed refueling system is erected on the ground, so that both refueling systems are installed side by side. However, the hose storage device 1 is arranged above the refueling position formed by the refueling machine case 12.

FIG. 4 shows a block diagram of the embodiment, and the control device 20b includes the main switch 23, the lower switch 9, the higher switch 8, the return switch 22, the hose position detector 7, and the flow rate/L/pass transmitter 17b. The output signal of is introduced,
It introduces output signals to the hose reel motor 6, pump motor 16b, and display 21. Information storage stores information displayed on the display 21, such as campaigns other than numbers indicating the amount of refueling. means 25, a counting means 26 which receives a pulse signal from the flow rate pulse transmitter 17b and calculates the pulse signal to measure the flow rate; a time measuring means 27 which sets the display time of the refueling amount and times it; turning on the hose reel motor 6; It is comprised of a hose reel motor control means 28 that controls turning off and forward/reverse rotation, and a pump motor control means 29 that controls turning on and off of the pump motor 16b.

Next, the usage and operation will be explained with reference to the flow chart in Fig. 5. When the gas station opens, the main switch 23
When turned on (Step I), the control device 20b operates and the information stored in the information storage means 2S is displayed on the display 21.
Product advertisements and other information are displayed here (StenoPro), and in this state it waits for customers.

Then, when a customer comes, the car is stopped at a refueling position below the hose storage device 1, that is, near the refueling machine case 12,
When you turn on the hose lowering switch 9 (Stenpuha)
This ON signal enters the hose reel motor control means 28, which causes the hose reel motor 6 to rotate in the normal direction, causing the hose reel 3 to rotate and the refueling hose 5b to descend. At the same time, the previous customer's refueling amount stored in the counting means 26 is reset to zero, the connection between the display 21 and the information storage means 20b is released, and the output signal from the counting means 26 is input to the display 21. The display 21 becomes a zero display (step 2).

When the refueling hose 5b further descends and is located at the lower end, the hose position detector 7 detects this (snap), and its output goes into the hose reel motor control means 28, which controls the hose reel motor. 6 stops, and the refueling hose 5b stops at the lowered position. At the same time, the pump motor 1 is controlled by the output of the pump motor control means 29.
6b starts rotating and becomes ready for refueling (to step).

Therefore, when the refueling nozzle 4b is opened and refueling is performed, the discharge amount is input to the counting means 26 as a pulse signal from the flow rate pulse transmitter 17b, and is calculated here and output to the display 21, where the refueling amount is displayed. .

When refueling is completed and the lift switch 8 is turned on (step switch), this on signal is sent to the hose reel motor control means 28.
and the pump motor control means 29, and the hose reel motor 6 is reversed by the output of these control means 28, 29 to wind up the refueling hose 5b, and at the same time, the pump motor 16b is stopped (sterapuri).

Then, when the refueling hose 5b is further wound up and reaches the raised position, the hose position detector 7 detects this and its output goes into the hose reel motor control means 28, which causes the hose □ reel motor 6 to stop. Then, the refueling hose 5b stops at the raised position.

During this time, the amount of refueling continues to be displayed on the display 21, but when the time set in the timer 27 (for example, 30 seconds) has elapsed (STELLA PULL), the display switches from the amount of refueling to displaying other information (STELLA PULL). After the display has been switched to the information display, if you want to display the refueling amount again for confirmation etc., turn on the return switch 22 (Sterapuri), and this on signal is input to the information storage means 25 and the counting means 26. The amount of oil supplied is displayed on the display 21 again (step force). Then, after checking the amount of refueling, turn off the return switch 22, or after a certain period of time (for example, 10 seconds) has elapsed (
Stesopyo), switches to information display again (Suterapuri)
.

In this way, after refueling is completed, information continues to be displayed on the display 21 until the next customer arrives.

Note that after refueling, if the next customer comes and turns on the hose lowering switch 9 while the refueling amount is still displayed on the display 21, the next customer will return to step 2 and turn on the hose reel. The motor 6 rotates normally and the refueling hose 5b is lowered, and at the same time, the currently displayed amount is immediately returned to zero.

〔Effect of the invention〕

As described above, the refueling device of the present invention reduces the number of refueling devices installed on the ground by installing a fixed refueling device on the ground and a suspended refueling device, thereby making effective use of the site. In addition, the refueling position of the suspended refueling system is clearly indicated on the island of the ground-fixed type, making it easy to find the refueling position. In addition, the amount of refueling performed using a hanging refueling hose is displayed on a display attached to the top of the refueling machine case near the refueling point, making it easy to see the amount of refueling from the refueling position and making the entire device more compact. This allows for efficient use of space within the gas station.
