Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a suspended refueling device having a refueling machine installed on the top thereof.

"Prior Art" In order to make the present invention easier to understand, a conventional suspension type oil supply device will first be described with reference to FIG. In a conventional suspended type refueling system, a hose handling device 4 is provided from a canopy 1 of a refueling station via a hanging strut 2.2. There is a hose storage (not shown) inside the hose processing device 4.
For example, a hose reel is stored therein. The downstream side of the refueling hose 5 wrapped around the hose reel and stored is a hose processing bag w4.
The end of the refueling hose 5 is connected to a refueling nozzle 6.
The upstream side thereof is connected to an underground tank 8 via a refueling vibe 7 passing through one of the pillars 2. In addition, near the refueling nozzle 6, a switch box 11 houses a hose lowering switch 10 including a hose raising switch 9 and a string 10a for the hose lowering switch. The refueling vibrator 7 is provided with a pump 13 driven by a motor 12, and this pump 13 sucks oil from an underground tank 8, sends it to the refueling hose 5 via a flow meter 14, and causes it to flow out from the refueling nozzle 6. It has become. The flowmeter 14 is provided with a flow rate pulse transmitter 15, and based on the flow rate pulses outputted from the flow rate pulse transmitter 15, a control device (not shown) indicates the amount of refueling on a display meter 17 provided on the wall surface 16 of the filling station. It grows to display.

By the way, in a gas station where a plurality of such refueling devices are installed, the same number of display meters 17 as the hose processing devices 4 are installed side by side on the wall surface 16, so depending on the case, which display meter 17 indicates which one is being refueled during refueling. It is possible to make a mistake in determining whether the device is compatible with the device.

Furthermore, providing the display meter 17 and the hose processing device 4 at separate locations requires troublesome construction of connecting wires and cables. In order to eliminate this drawback, it is conceivable to suspend the display meter 17 from the hose processing device 4 or its vicinity for easy understanding. However, this poses a problem as it becomes an obstacle to the passage of large vehicles such as large trucks with a high vehicle height.

[Object of the Invention] The present invention has been made in view of the above-mentioned problems, and its object is to provide a refueling device that does not cause misreading of the display meter and does not obstruct the passage of vehicles.

[Structure of the Invention] The suspended oil supply device according to the present invention is provided with an indicator movable to an upward position in or near the hose treatment device.

[Operations and Effects of the Invention] Therefore, since a display meter that can be moved upward is provided in or near the hose treatment device, when there is no large vehicle below the hose treatment device, the display meter is moved to a lower position where it can be easily seen, and When a vehicle is present, the display meter can be moved to an upper position where it will not interfere with large vehicles. In addition, since the display meter is installed integrally with or near each hose processing device, installation and wiring work is easier than when the display meters are installed side by side on the wall of the gas station, and construction costs can be reduced. .

[Preferred Embodiment] When carrying out the present invention, a display meter is provided near the end of the hose processing device that stores the hose of the refueling device via a rotatable arm, or is extendable and retractable at the upper part near the bows processing device. Preferably, it is suspended via a free arm. Furthermore, when carrying out the present invention, the hose processing device is provided with a vehicle height sensor that detects a vehicle that is over a certain vehicle height and a detection switch that detects the elevation of the hose in conjunction with the hose elevation device, and a display meter is provided near the refueling nozzle. A lift switch is provided to move the display meter to the lower position or in the direction of the lower position when the vehicle height sensor is not detected or when the hose is lowered and the display meter lower switch is pressed, and the display meter lift switch is pressed. When the vehicle is detected by the vehicle height sensor and the hose is rising,
Preferably, the indicator is moved in the direction of or to the upper position. Note that the vehicle height sensor may not be provided for each hose processing device, but may be a sensor such as an image sensor that can detect the entire gas station. In this way, installation work and wiring work for the vehicle height sensor are easy, and construction costs can be reduced.

Note that if the lower position of the indicator is set low enough to prevent it from hitting vehicles other than large vehicles such as passenger cars, it can be used as a driving guide for these vehicles.

[Example] The present invention will be described in detail below with reference to FIGS. 1 to 4. In these drawings, parts corresponding to those in FIG. 5 are designated by the same reference numerals, and redundant explanation will be omitted.

In FIG. 1, a canopy 1 of a gas station is provided with four refueling devices 3 to 3, and each refueling device 3 has one side of a hose processing device 4, as shown in detail in FIG. A display meter 17 is provided via a rotatable arm 18 near the end.
is installed.

These rotating arms 18 are fixed to a horizontal shaft 19.

The horizontal shaft 19 is rotated by a lifting device provided in the hose processing device 4, that is, a motor 20 capable of forward and reverse rotation. This motor 20 is reversed and the display meter 17
is rotated to a horizontal upper position higher than the bottom surface of the hose processing device 4 as shown by a chain line, and rotated forward to rotate the indicator 17 to a lower position as shown by a solid line. The lower position of the display meter 17 is at an angle slightly shallower than vertical, and the height is such that the display surface 17a of the display meter 17 is at a height that does not hit vehicles other than large vehicles such as passenger cars. It is slanted to make it easier for people to see it.

A vehicle height sensor 21 is provided on the bottom of the hose processing device 4, and is capable of detecting a vehicle over a certain vehicle height, that is, a large vehicle. A detection switch 22 is provided which is linked to the hose lifting device and detects the lifting state of the hose.When the refueling hose 5 is in the storage position, the hose rise detection switch 22a is closed, and when the refueling hose 5 is in a position other than the storage position, the hose drop detection switch 22a is closed. 22b is closed.

On the other hand, near the refueling nozzle 6, an indicator up/down switch 23 is provided at the top of the switch box 11, and when the indicator up/down switch 23a of the switch 23 is closed, the motor 2
0 rotates in the reverse direction, and when the indicator lowering switch 23b is closed, the motor 20 rotates in the normal direction.

Further, when the vehicle height sensor 21 is not detected, the motor 20 rotates in the forward direction to rotate the display meter 17 to the lower position, and also rotates the display meter 17 to the lower position.
Even if the hose is detected by the vehicle, the hose lowering detection switch 22b
is closed and the indicator lowering switch 23b is closed, it rotates in the normal direction and rotates the indicator 17 in the downward position direction. In addition, when the hose rise switch 22a is closed, the motor gear O rotates in reverse when the vehicle height sensor 21 detects it, and rotates the indicator 17 to the -[ direction, and while the indicator rise switch 23a is closed, it reverses. Rotate the display meter 17 in the upward position direction.

Next, the operation will be explained mainly with reference to FIG.

When the vehicle height sensor 21 is not detected, that is, when there is no vehicle below the refueling system or when there is a vehicle other than a large vehicle such as a passenger car (Case 1), the motor 20 rotates in the normal direction and the indicator 17 is moved to a lower position for easy viewing. It looks like this. The vehicle to be refueled then stops at the refueling position with this descending indicator as the target.

Next, when the worker pulls the hose lowering switch string 10a to lower the hose 5, the hose lowering detection switch 22b is closed, and the pump motor is driven to open the nozzle 6 to perform refueling. When refueling a passenger car, etc., if the indicator 17 becomes an obstacle to the passage of a large vehicle, close the indicator rise switch 23a.Case 2) The motor 20 is reversed and the indicator 17 is rotated to the upper position. Ru. When the indicator 17 reaches a safe and easy-to-see position that does not interfere with the large vehicle, the switch 23a is opened and held at that position to continue refueling. When refueling is finished, pressing the hose rise switch 9 causes the hose to rise, the pump motor stops, and the hose rise detection switch 22a closes.

If a large vehicle enters the warehouse while the hose is being raised, the vehicle height sensor detects this, the motor 2o is reversed, and the indicator 17 is rotated to the upper position (Case 3).

When the hose lowering switch string 10a is pulled to close the hose lowering switch 10 and the refueling hose 5 is lowered, the hose lowering detection switch 22b is closed. When the indicator lowering switch 23b is closed in this state (case 4), the motor 20 rotates in the normal direction and the indicator 17 is rotated in the downward direction. When the display meter 17 is in a position where it can be easily seen without coming into contact with a large vehicle,
The switch 23b is opened and held in that position to refuel.

When refueling is completed, close the hose rise switch 9 to raise the refueling hose 5, and the hose rise detection switch 22a
closes. In this state, the vehicle height sensor 21 detects a large vehicle, so as in case 3, the motor 20 is reversed and the indicator 17 is rotated to an upper position where it does not obstruct the passage of the large vehicle. When the large vehicle leaves the vehicle, the vehicle height sensor 21 no longer detects the large vehicle, so return to case 1 described above.
The indicator 17 is rotated to the lower position.

FIG. 3 shows another embodiment of the present invention, in which the indicator 17 is vertically suspended from the -F section near the hose treatment device 4, that is, the canopy 1, via a telescopic arm 24.

These extendable arms 24 are driven by a lifting device 25 provided on the canopy 1 and operating in forward and reverse directions. This lowering device 25 operates in the opposite direction to lower the telescopic arm 24.
is contracted and the bottom of the display meter 17 is moved to an upper position that is approximately the same as the bottom surface of the Bose processing device 4 as shown by the chain line, and operated in the forward direction to extend the telescoping arm 24 and the display meter 17 is shown by the solid line. It is designed to move to a downward position like this. The height of the lower position of the indicator 17 is set to a height that does not hit vehicles other than large vehicles such as passenger cars. Other than this, the construction is the same as in FIG. 2, and the same operation and effect as in FIG. 2 is achieved.

[Summary] As explained above, according to the present invention, a display meter that can be moved upward is provided at or near the hose processing device, so when there is no large vehicle below the fuel supply device, the display meter can be moved to a lower position where it is easy to see. When a large vehicle is present, the display meter can be moved to an upper position where it will not interfere with the large vehicle. Therefore, there is no misreading of the display at this gas station.
It also does not obstruct the passage of large vehicles. −
