Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a refueling device for refueling kerosene installed at a refueling station for refueling automobiles with oil such as gasoline.

[Conventional technology]

At gas stations, they are lined up with gasoline refueling equipment for cars, etc.
Kerosene refueling equipment is installed near the corners of the site.

Conventionally, as shown in FIG. 5, for example, in this refueling system, a refueling pipe that communicates with an underground refueling tank is set up in a refueling machine case 33 installed above ground, and the refueling pipe is connected to a refueling motor in the middle of the refueling pipe. A refueling mechanism such as a refueling pump and a flowmeter connected to a flow rate pulse transmitter is installed, and a refueling hose 35 having a refueling nozzle 34 at the tip is connected to the refueling pipe on the discharge side of the flow needle. A keyboard 36 for presetting the amount of oil to be supplied and a display 37 for the amount of oil to be supplied are provided.

To refuel, place a container such as a plastic tank on the ground near the case 33, use the keyboard 36 to set the refueling amount, such as 181.20f, depending on the capacity of the container, and connect the refueling nozzle 34 to the case. 33 and its tip is inserted into the container.

[Problem to be solved by the invention]

With such devices, refueling is done by placing a container such as a plastic tank directly on the ground and holding the refueling nozzle at the end of the refueling hose with your hand. However, since the plastic tank is very light, it is difficult to refuel, especially when starting refueling. Immediately after that, when there is still not much kerosene in the plastic tank, there are cases where the fuel nozzle or fuel hose pushes the plastic tank and knocks it over, which not only reduces work efficiency but also causes kerosene to flow onto the ground. It was also dangerous.

In addition, kerosene is often filled in plastic tanks, and most of the plastic tanks used have capacities of 18β and 2ON, but it is troublesome as it is necessary to preset the same value each time you refuel. Met.

It is an object of the present invention to solve the above-mentioned disadvantages of the conventional example, and to provide a method that makes it easy to set the amount of oil to be supplied to a quantitative container such as a plastic tank, maintains a stable state during refueling, and is safe. To provide a lubrication device which can freely supply lubrication of an arbitrary set amount to objects.

[Means to solve the problem]

In order to achieve the above object, the present invention branches a refueling pipe on the discharge side of a flow needle, connects one branch pipe to a refueling hose having a refueling nozzle at its tip, and connects the other branch pipe to a refueling nozzle exclusively for quantitative refueling. is connected to a refueling pipe provided at the tip thereof, and a holding means for a container to be refueled is provided below the refueling nozzle exclusively for quantitative refueling.

[Effect]

According to the present invention, when refueling a metered container such as a plastic tank, if the container is supported by the container holding means and oil is discharged from the refueling nozzle dedicated to metered refueling above the container, the container will not fall over. Refueling is carried out in a stable condition without fear of In addition, to supply a desired amount of oil to something other than such a container, it is sufficient to use another refueling nozzle provided on the refueling hose.

〔Example〕

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

Fig. 1 is a partially cutaway front view showing an embodiment of the refueling device of the present invention, and Fig. 2 is a vertical sectional side view of the same. Adjacent refueling machine cases for quantitative refueling are shown, and both refueling machine cases 1 and 2 are erected on an island 3 installed on the ground.

The refueling machine case 1 for refueling an arbitrary amount has a refueling pipe 4 connected to an underground refueling tank (not shown) built up inside, and a refueling motor 5 connected to the middle of the refueling pipe 4, as in the conventional case. A flow meter 8 to which a pump 6 and a flow pulse starter 7 are connected is provided, and a display 9 for displaying the amount of oil to be supplied and a keyboard 10 for setting the amount of oil to be supplied are provided on the front side.

In the present invention, in the oil supply device having such a configuration, the oil supply pipe 4 on the discharge side of the flow meter 8 is branched, and one branch pipe 4a is connected to the valve 13.
A refueling hose 1 having a refueling nozzle 11 at its tip via a
Connected to 2. In the figure, reference numeral 14 indicates a nozzle switch that is turned on and off in conjunction with the hooking and unhooking of the refueling nozzle 11.

On the other hand, the refueling machine case 2 for quantitative refueling has a cavity 16 in the center for storing a refueling container 15 such as a plastic tank, and a mounting table serving as a holding means for the refueling container 15 below the cavity 16. 17 is provided outside the case 2 so that it can be freely drawn out in the horizontal direction.

This mounting table 17 is formed into a box shape with a rope 18 for collecting garbage stretched on the upper surface and an oil leakage catcher 19 below the rope. is provided with a handle 21.

In the upper part of the space 16, the tip of the other branch pipe 4b on the discharge side of the flow meter 8 is opened via the valve 13b, and a refueling nozzle 2 exclusively for fixed-quantity oil supply is installed at the tip of the branch pipe 4b.
A hose 23 with two hoses was connected.

Reference numeral 24 in the figure indicates a lever for raising and lowering the refueling nozzle 22. One end of the lever 24 protrudes outside the case 2 through a lock portion 25 formed by cutting the front plate of the case 2 into an L shape, and the other end is attached to the case 2 by being automatically biased counterclockwise by a spring 26.

In addition, a keyboard 27 is provided on the front of the case 2.
82.201 Preset button for refueling settings 28゜29
and a refueling switch 30 for starting refueling. and an emergency stop switch 31.

In this way, a control device 32 using a conventionally known microcomputer or the like is arranged in the case 1, and as shown in the block diagram of FIG. Setting signal of 2 korutsuchi,
Pulse alarm control device 32 from the flow rate pulse transmitter 7
A control signal from the control device 32 was introduced to the refueling motor 5, the valves 13a and 13b, and the indicator 9.

Next, the usage and operation of the flowchart in FIG. 4 will be explained.

First, in the case of precent refueling, in which an arbitrary amount is set and refueled, input the desired refueling amount using the keyboard 10 provided in the case 1, and remove the refueling nozzle 11 from the nozzle hook. is very step-by-step)
, this ON signal is output to the control device 32.

As a result, a control signal from the control device 32 enters the valve 13a, opens the valve 13a, and at the same time is output to the refueling motor 5, turning it on, driving the refueling pump 6, and causing the display 9 to return to zero ( step mouth). Since this is preset refueling (Step 3), when the tip of the refueling nozzle 11 is inserted into the container to be refueled and the nozzle valve is opened, the oil pumped from the underground oil storage tank to the refueling pipe 4 by the refueling pump 6 will be pumped into the refueling pipe 4 by the flow meter. 8. The oil is discharged from the oil supply nozzle 11 through the branch pipe 4a and the oil supply hose 12 and into the container to be oiled.

At this time, the flow rate measured by the flowmeter 8 is output as a pulse signal from the flow rate pulse transmitter 7 to the control device 32 (Step 2), and the amount of oil supplied counted here is displayed on the display 9 (Step H). . When the amount of oil supplied reaches the set amount (step), the valve 13a is closed by the action of the control device 32, the oil supply motor 5 and the oil supply pump 6 are stopped (stepped), and the oil supply ends. Note that even before the refueling amount reaches the set amount, if the refueling nozzle l'l is hooked to the nozzle hook and the nozzle switch 14 is closed, the refueling motor 5 is stopped (step port) and refueling is completed.

Next, we will explain the case of normal refueling, where the refueling amount is not set in advance and, for example, the container to be refueled is refueled until it is full. When the nozzle switch 14 is turned on (step 1), the display 9 returns to zero and the valve 1 is turned on.
3a opens and the refueling motor 5 turns on (step port).
Since it is not preset lubrication (Step 3), when the tip of the lubrication nozzle 11 is inserted into the container to be lubed and lubrication is carried out, the pulse signal emitted from the flow rate pulse transmitter 7 enters the control device 32 (Step port) and is counted here. The amount of refueling that has been done is displayed on the display 9 (Snap Nu).

When the tank to be refueled is full, or when the desired amount of refueling is reached, the refueling nozzle 11 is returned to the nozzle hook and the nozzle switch 14 is closed (stellar pull), the nozzle return off signal is sent to the control device. 32, as a result, the valve 13a closes and the refueling motor 5 stops (
step) refueling is completed.

Next, a case of quantitative oil supply in which a predetermined amount of oil is supplied, for example 18f, 201, will be explained.

First, hold the handle 21 and pull out the mounting table 17 toward you, place the container 15 to be refueled, such as an 18J plastic tank, on the mounting table 17 with the refueling port facing you, and then put the mounting table 17 back into the case. Push it inside. At this time stopper 20
The mounting position of the refueling container 15 is regulated by this, and the refueling port is positioned below the refueling nozzle 22.

Then, the lever 24 is pushed down against the elasticity of the spring 26 and engaged with the lock portion 25 to push the refueling nozzle 22 into the refueling port and turning on the refueling switch 30 (step port).

At this time, while refueling is being performed on the refueling machine case 1 side for arbitrary amount refueling, that is, when the nozzle switch 14 is turned on, even if the refueling switch 30 is turned on on the refueling machine case 2 side for quantitative refueling, the nozzle switch 14 is turned on. Since the signal is not inputted to the control device 32, it is possible to prevent arbitrary and constant amount of oil replenishment during opening.

Then, when the preset button 28 is turned on (step port), the display 9 returns to zero, and the branch pipe 4 on the discharge side of the flowmeter 8
The refueling motor 5 is turned on at the same time as the valve 13b provided at the valve 13b is opened (step force).

Then, the oil supply pump is driven and oil is discharged from the oil supply nozzle 22 into the oil supply container 15. At this time, even if the container 15 to be refueled is a light one such as a plastic tank, the container 15
is placed in the space 16 inside the case 2 on the mounting table 17,
In addition, since the refueling nozzle 22 is also fixed by the lock portion 25 and the lever 24, there is no risk that the refueling container 15 will move during refueling due to being pushed by the refueling nozzle 22 or a person's foot.

The flow rate is output as a pulse signal from the flow rate pulse transmitter 7 to the control device 32 (Snap Yo), and the amount of refueling counted here is displayed on the display 9 (Stella Play).

When the refueling amount reaches the set amount of 18β (Stella Pre)
, the valve 13b is closed by the action of the control device, the refueling motor 5 is stopped, and refueling is completed (stellar play).

:In addition, if you refuel with oil remaining in the refueling container 15 and the tank becomes full before reaching the set amount, press the emergency stop switch 31. (Stella Play) Refueling ends.

In this case, the oil leaking out from the oil supply container 15 passes through the net 18 on the upper surface of the mounting table 17 and collects in the oil leakage catcher 19 below, so that it does not flow out to the surroundings.

When refueling is completed, raise the lever 24 to release the lock, remove the refueling nozzle 22 from the refueling port of the refueling container 15, and pull it toward you by the handle 21.
slides forward, so the refueling container 15 above can be taken out from the case 2 in a stable state.

The oil accumulated in the oil leakage receiver 19 can be drained as appropriate, and since the l1li18 is provided above the oil leakage receiver 19, there is no risk of large dirt or the like getting into the oil leakage receiver 19.

〔Effect of the invention〕

As described above, the refueling device of the present invention allows the user to easily set the amount of refueling to a metered refueling container such as a plastic tank with a single touch, and is safe because the refueling device can maintain the container in a stable state.

Furthermore, the amount of oil supplied can be freely set, and the range of application is wide.
