Description

[Detailed description of the invention] The present invention relates to a suspended oil supply device.

In a suspended type refueling system, a pipe that communicates with the oil storage tank via a pump and a meteor needle is raised above the refueling point, and a refueling bow having a nozzle valve at the lower end is connected to the above piping via a bow lifting device. The lift switch installed near the nozzle valve activates the lift device to raise and lower the refueling bow, but conventionally, when the lift switch is activated, it automatically increases the refueling area to the limit stipulated by the Fire Service Act. The refueling bow was extended to the maximum length, that is, until the nozzle valve touched the ground.

Therefore, if you hold the nozzle valve incorrectly while it is descending, the nozzle valve will hit the ground.
There is a risk of damaging the nozzle or the electronic equipment attached to it.

In addition, when refueling, the nozzle valve must be lifted up to the refueling port position, and the extra weight of the bow is placed on the nozzle valve, making it difficult to operate. Since there is no refueling hose and most of the 1Rffl nozzle valves, I have to manually operate them.

Furthermore, if you accidentally let go of the nozzle valve while refueling, there is a risk that the nozzle or the electronic equipment attached to it may hit the ground and be damaged. There were drawbacks such as the long time it took to start refueling.

The purpose of the present invention is to eliminate the above-mentioned disadvantages of the conventional example, maintain the conventional refueling area (U), temporarily stop the refueling bow at a position where the nozzle valve is close to the ground, and then manually release the nozzle valve. Even if you hold the nozzle valve by mistake, the nozzle valve and electronic devices attached to it, such as the cart reader and preset switch, will not hit the ground and be damaged, and the weight added to the hand holding the nozzle valve when refueling will be reduced. To provide a H%lJ, V-type refueling device which has good operability in refueling and takes a short time to start refueling.

However, according to the present invention, the purpose of the lever is to raise the piping communicating with the oil storage tank via the pump and the flow meter above the refueling point, and to connect the refueling hose having the nozzle valve at the lower end to the above point via the Bose lifting device. This is achieved by securing a lowered position of the hose that allows refueling between the upper raised position and the lowered maximum position of the hose in a suspended type oil supply device connected to the piping.

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

Fig. 1 is a partially cutaway side view of the 1U vertical type oil supply system of the present invention, and Fig. 2 is a block circuit diagram of the upper part. Oil supply pump 3
A motor 5 is connected to the oil supply pump 3, and a flow rate pulse transmitter 6 is attached to the flow meter 4.

A refueling hose 8 having a nozzle valve 7 at its tip is connected to the piping 2 via a hose lifting device 9 suspended from a canopy 10.

Attached to the nozzle valve 7 are an 811 type lift switch 11 for the refueling boss 8, and an electronic device 13 including a card reader, a precent switch, and the like.

In addition, numeral 14 in the figure is a refueling amount display meter installed at an easily visible position such as on the wall of the gas station.

As shown in FIG. 2, the position detection output signal A of the nozzle valve position detection device 15 connected to the Bose lifting device 9 is
Jl consisting of a sequencer or microcomputer using 0 circuit
output signals -1, -t 13 for normal rotation, reverse rotation, and stop are introduced from the i1i control sub-control 6 to the drive motor 17 of the Bose lifting device 9.

The position detection output signal A emitted from the nozzle valve position detection device 15 indicates that the nozzle valve 7 is in a refueling standby state where refueling is not possible, that is, the rising position is 1 it, that the nozzle valve 7 is close to the ground (hereinafter referred to as the X position), and Refueling status rQ
At the hose lowering position (hereinafter referred to as 7th position), the nozzle valve 7 is lowered to a position between the ground surface and the lifting device 9.
The maximum descending position of Bose, which is the state where refueling is possible, (hereinafter referred to as X
(referred to as "position") includes detection signals for the three positions XYZ.

The on/off output signal C from the control means 16 is introduced into the motor 5, and the reset signal C from the control means 16 is reset 34-1i.
The output signal G from the lift switch 11 is introduced into the control means 16, and the flow rate signal from the flow rate pulse transmitter 6 is introduced into the counting circuit 18.
The d11 signals E and E' of 8 are increased by m to the display meter 14 and the control means 16, respectively.

Next, usage and operation will be explained.

FIG. 3 is a flowchart showing the operation of the block circuit of FIG. 2, in which when the lift switch 11 is pulled, the switch 1
1, the output signal G enters the control means I6 (steptor)
.

If the nozzle valve 7 is currently at the X position, a signal indicating the X position is sent from the nozzle valve position detection device 15 to the control means 1.
6 and the signal G from the lift switch 11
In response, the control means 16 (steso buoy) sends an output signal B whose content is normal rotation, causes the motor 17 to rotate in the normal direction, and the bow reel of the bows n1 lowering device 9 connected thereto rotates in the normal direction, causing the refueling port 8 to rotate in the normal direction. Descend (step mouth).

When the nozzle valve 7 reaches the 7th position (step), the nozzle valve position detection device 15 detects this and sends an output signal A to the control means 16.

As a result, the control means 16 sends a seven-level signal F to the oil supply amount display meter 14 via the counting circuit 1, the oil supply amount display meter 14 is reset, and an output signal F indicating ON is sent.
4C is sent to the motor 5, the motor 5 rotates and the pump 3 is driven (Ste Nobuni), making it possible to refuel. At the same time, the control means 16 sends an output signal B indicating a stop to the motor 17, so the motor 17 stops rotating, the hose reel of the hose lifting device 9 also stops rotating, and as a result, the lowering of the bow 8 stops. , the nozzle valve 7 stops at the Y position (step E).

However, if you lower the refueling hose 8 to this Y position and the length of the hose 8 is insufficient for refueling, you can pull the lifting switch support 1 again.
, at this time, the signal indicating the Y position from the Z-lube position detection device 15 is being input manually to the control means 16, and the lubricant has not yet been refilled (to step).
Then, the control means 16 lowers the refueling hose 8 again (step).

If Bose 8 descends to the X position (Sute Nopuwo)
, the nozzle position detection device t15 detects this and sends an output signal A to the control means 16, and as a result, the nozzle valve 7 is stopped at the X position in the same way as when the nozzle valve 7 is stopped at the Y position. (Stesopho).

When the nozzle valve 7 is inserted into the fuel filler port of a car and opened, the pump 3 and motor 5 pump the underground fuel tank 1.
The oil sucked up is supplied from the nozzle valve 7 via the piping 2 and the oil supply hose 8.

The flow rate measured by the flowmeter 4 is sent from the flow rate pulse transmitter 6 as a flow rate signal to the counting circuit 18 and counted there, and the counting circuit 18 sends a counting signal E to the oil supply amount display meter 14 and the control means 16. It will be done.

The oil supply amount display meter 14 displays the relevant oil supply amount.

Note that the count signal E' inputted to the control means 16 is a signal for determining whether or not refueling has been performed.

When refueling is finished, pull the lift switch 11 (
output signal G from the switch 11 enters the control means 16. At this time, since a signal indicating the X position is input from the nozzle valve position detection device 15, the control means 16 judges it and converts it into steps. 5, and the motor 5 and pump 3 are stopped (Stesopwa).

In addition, since the output signal B indicating a reverse rotation is sent to the motor 17 to reverse the motor 17, the hose reel of the bow lifting device 9 connected thereto is reversed, and the refueling bow 8 is raised (Stetsopka).

When the nozzle valve 7 reaches the X position (Sute Nobuyo),
The nozzle valve position detection device 15 detects this and sends an output signal A to the control means 16, whereby the control means 16
sends an output signal I3 indicating a stop to the motor 17, so that the rotation of the motor 17 is stopped, and the rotation of the bow reel of the bow lifting device 9 is also stopped, and as a result, the hose 8
The nozzle valve 7 stops rising and the nozzle valve 7 stops at the X position, preparing for the next refueling.

Incidentally, in reality, there are few cases in which refueling must be performed at the X position, that is, when a car or the like is
In many cases, it is possible to stop directly below and refuel at the Y position.

If you refuel at the Y position, press the lift switch 1 after refueling.
1 (step), at this time a signal indicating the Y position is input from the nozzle valve position detection device 15, so the control means 16 judges it. Count signal I from the counting circuit 18
Since the E
is sent to the motor 5, and the motor 5 and pump 3 are stopped (step 1).

In addition, the control means 16 sends an output signal B indicating a reverse rotation to the motor 17, causing the motor 17 to reverse, so that the bow reel of the hose lifting device 9 connected thereto is reversed, and the refueling port 8 is raised (stesopre). .

When the nozzle valve 7 reaches the X position (Sutesopnu),
The nozzle valve position detection device 15 detects this and sends an output signal A41- to the control means 16. Due to the dirt, the control means 16 sends an output signal B indicating a stop to the motor 17, so that the rotation of the motor 17 is stopped. The rotation of the bow reel of the hose lifting device 9 also stops, and as a result, the hose 8
The nozzle valve stops rising at the X position (Step 7), and prepares for the next refueling.

As described above, in the suspension type refueling system of the present invention, the piping that communicates with the oil storage tank via the pump and the flow rate needle is raised above the refueling point, and the refueling bow having the nozzle valve at the lower end is connected to the hose lifting device. In the suspended type oil supply device connected to the above piping via the bow, we have ensured a bow lowering position where oil can be supplied between the bow raising position and the bosu maximum lowering position, so even if you forget to carry the nozzle valve while descending, the nozzle This prevents damage to the valve and its electronic devices, such as card readers and preset switches, by pushing them on the ground, and also reduces the weight on the hand holding the nozzle valve when refueling, making it easier to operate the refueling operation. It has good performance, and the amount of bosu that is fed out is small and the time required to start refueling is short.
