Description

  The present invention relates to an oil supply apparatus that supplies a plurality of types of fuel oil to an automobile, and that can supply a desired oil type selected from a plurality of types of fuel oil from one oil supply nozzle.

In a fueling station, a plurality of fueling systems are housed in a housing of a fueling device so that various fuel vehicles can be used, and a fueling nozzle is provided for each fueling hose of each fueling system. If the oil supply nozzle is provided for each oil supply system in this manner, the cost of the oil supply device increases and becomes expensive, and it is necessary to select the oil supply nozzle for each oil type, resulting in a reduction in work efficiency.
In addition, the oil supply hose is provided in the oil supply device for each oil type, so that the oil supply hose is positioned in front of the operation unit of the data input / output device and the display unit of the display unit, which obstructs operation and display, and equipment layout. Impedes the degree of freedom.

The present applicant has proposed a fueling device in which a plurality of fueling systems are housed in a housing, a fueling pipe of each fueling system is connected to a single fueling hose, and a fueling nozzle is provided on the fueling hose (patent) Reference 1).
Although the related art related to such a proposal is effective, there is a disadvantage that oil in the oil supply hose and the oil supply nozzle is discharged and mixed when different types of oil are supplied. The amount of oil in the oil supply hose and the oil supply nozzle is a large amount of about 1.2 L, which is unpleasant for the customer, and the settlement of the mixed oil amount is unclear. If the oil quality is different as in light oil, it causes engine trouble and is dangerous.

For this reason, there has been proposed an oil supply device in which a plurality of oil supply systems are housed in a housing and an oil supply hose of each oil supply system is connected to one oil supply nozzle (see Patent Document 2).
Such an oil supply device (the oil supply device of Patent Document 2) is effective, but the oil mixture in the oil supply nozzle in the case of supplying different oil types has not been eliminated. The amount of oil in the oil supply nozzle is a small amount of about 0.2 L, but it is unpleasant for the customer. If the oil quality is different like light oil, even a small amount may cause engine trouble.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a fueling device of the present invention, and two sets of fueling systems 3 and 4 are incorporated in a lower portion of a housing 2 of the fueling device 1.
An oil supply pipe 5 of one oil supply system 3 is connected to an oil storage tank 6 of high octane gasoline, for example. A pump 8 driven by a motor 7 and a flow meter 10 having a flow rate pulse transmitter 9 are interposed in the oil supply pipe 5 and connected to an oil supply nozzle 12 via an oil supply hose 11.

The oil supply pipe 13 of the other oil supply system 4 is connected to an oil storage tank 14 for regular gasoline, for example. A pump 16 driven by a motor 15 and a flow meter 18 having a flow rate pulse transmitter 17 are interposed in the oil supply pipe 13 and connected to the oil supply nozzle 12 via an oil supply hose 19.
The fueling nozzle 12 is configured to be hung on a nozzle hanger 20, and the nozzle hanger 20 is provided with a nozzle switch 21.

An oil supply control device 22, a data input / output device 23, and a display 24 that displays the amount of oil supply are provided on the upper portion of the housing 2. Here, the data input / output device 23 is configured to input an oil type / amount to be refueled and issue a refueling slip.
The oil supply control device 22 receives an on / off signal from the nozzle switch 21, and receives a flow rate signal from the flow rate pulse transmitters 9 and 17 of the flow meters 10 and 18. On the other hand, a drive signal for the motors 7 and 15 for driving the pumps 8 and 16 is transmitted from the fuel supply control device 22, and a fuel supply amount display signal is transmitted to the display 24.
The oil supply control device 22 and the data input / output device 23 are configured such that oil supply data is exchanged with a POS 25 provided in an office or the like, and the oil supply data is managed in the POS 25.

FIG. 2 is a perspective view of the fueling nozzle.
Two sets of valve mechanisms 27 and 28 are incorporated in the main body 26 of the oil supply nozzle 12.
A high-octane gasoline supply hose 11 is connected to an inlet 29 of one valve mechanism 27. A regular gasoline refueling hose 19 is connected to the inlet 30 of the other valve mechanism 28.
The outlets 31 and 32 of the two sets of valve mechanisms 27 and 28 are connected to a single discharge pipe 33.
Reference numeral 34 in FIG. 2 is a sight glass, which is provided on the side surfaces of the valve mechanisms 27 and 28 in order to visually check the discharged oil type. Here, the position of the sight glass 34 is not limited to the side surfaces of the valve mechanisms 27, 28, but can be provided on the upper surfaces of the valve mechanisms 27, 28.

FIG. 3 shows a cross section of one valve mechanism 27 of the fueling nozzle.
As described above with reference to FIG. 2, the high-octane gasoline refueling hose 11 is connected to the inlet 29 of the valve mechanism 27, and the outlet 31 is connected to the discharge pipe 33.
A main valve 36 is provided in the flow path 35 of the valve mechanism 27.
The main valve 36 is urged in the valve closing direction by a spring 37. The main valve 36 is opened by pushing up the valve rod 38 with a lever 39.
A check valve 40 is provided at the outlet 31 of the valve mechanism 27. The check valve 40 is urged in the valve closing direction by the spring 41 and is opened by the discharged fluid pressure.

A mechanism for holding and releasing the fulcrum of the lever 39 that opens the main valve 36 will be described with reference to FIG.
In FIG. 3, the upper chamber 43 of the first diaphragm 42 communicates with the flow path 35 via the liquid path 44. Diaphragm 42 is urged by spring 45 in the upward direction. The pin 46 fixed to the diaphragm 42 projects into the upper chamber 48 of the second diaphragm 47.
The upper chamber 48 of the second diaphragm 47 is open to the outer periphery of the distal end of the discharge pipe 33 via a negative pressure path 49. Here, a region in the middle of the negative pressure passage 49 communicates with a negative pressure generating portion 51 provided in the check valve 40.

The diaphragm 47 is urged in the downward direction by a spring 52 weaker than the spring 45. The diaphragm 47 has a backlash and is engaged with the pin 46 of the diaphragm 42.
The tip of the pin 53 fixed to the diaphragm 47 is formed in a conical shape 54 and is inserted into the support shaft 55. The support shaft 55 is urged by the spring 56 in the upward direction.
The support shaft 55 is provided with a hole 58 into which a locking ball 57 is fitted, and a lever 39 is supported by a support shaft 59 at the lower end of the support shaft 55.
Since the other valve mechanism 28 of the fueling nozzle is the same mechanism as the valve mechanism 27 described above, the details of the structure are omitted.

FIG. 4 is a sectional view showing the relationship between the main valve and the lever in the two sets of valve mechanisms 27 and 28.
The valve rod 38 of the main valve 36 of the valve mechanism 27 is engaged with the lever 39, and the valve rod 61 of the main valve 60 of the valve mechanism 28 is engaged with the lever 62.
The levers 39 and 62 are provided close to each other, but are configured separately. A person who supplies fuel can put the fingers on both levers 39 and 62 and simultaneously press both levers 39 and 62 so as to pull them up. However, as will be described later, only one of the levers 39 and 62 pressed so as to be lifted at the same time is lifted (movable upward), but the other cannot be lifted (cannot move upward). ).

FIG. 5 shows in cross section the check valves provided at the outlet in the two sets of valve mechanisms 27 and 28.
The outflow side of the check valve 40 provided at the outflow port 31 of the valve mechanism 27 and the outflow side of the check valve 63 provided at the outflow port 32 of the valve mechanism 28 are connected to a single discharge pipe 33.

Next, based on the flowchart of FIG. 6, operation | movement of the oil supply apparatus of this invention is demonstrated.
When the person who supplies the fuel operates the data input / output device 23 and designates a desired oil type, for example, high-octane gasoline (ST1 is YES), the designated oil type data is output to the POS 25 (ST2).
The POS 25 to which the oil type data is input (ST3 in POS of FIG. 6 is YES), the oil supply control device 22 sends a drive enable signal of a motor (for example, the motor 7) for driving the pump (for example, the pump 8) of the designated oil type. (ST4). And the oil supply control apparatus 22 memorize | stores the drive possible signal of the motor 7, for example (ST5).

When the oil supply nozzle 12 is removed from the nozzle hook 20 and an ON signal is input from the nozzle switch 21 to the oil supply control device 22 (YES in ST6), the oil supply control device 22 displays the previous oil supply amount displayed on the display 24. The display is returned to zero and the motor 7 is driven (ST7).
In this state, the driver or the person who performs the refueling operation inserts the discharge pipe 33 of the refueling nozzle 12 into the refueling port of the automobile and simultaneously presses the levers 39 and 62 so as to start refueling.

Referring also to FIG. 5 and FIG. 7, when the pump 8 is driven and the hydraulic pressure is applied to the upper chamber 43 (FIG. 5) via the flow path 35 and the liquid path 44, in the valve mechanism 27 on the high octane gasoline side, The diaphragm 42 descends against the spring 45, and the diaphragm 47 is lowered by the pin 46. When the diaphragm 47 is lowered and the pin 53 is lowered, the locking ball 57 is moved to the back of the hole 58 by the conical portion 54 and the spindle rod 55 is locked.
When the lever 39 is pulled in a state where the support shaft 55 is locked, the lever 39 is supported by the support shaft 55 and moved in the direction of pushing up the valve shaft 38. When the valve stem 38 is pushed up, the main valve 36 is opened against the spring 37 (FIG. 7).

On the other hand, in the regular gasoline supply system 28 in which the pump 16 is not driven, the hydraulic pressure does not act, the valve mechanism 28 remains in the state shown in FIG. I can't stop. Even if the lever 62 is pulled in this state, the support shaft 55 only moves down against the spring 56, and the valve stem 61 cannot be pushed up to open the main valve 60.
Thus, the valve mechanism 28 to which no hydraulic pressure is applied does not open the main valve 60 even if the lever 62 is pulled. Therefore, even if the levers 39 and 62 are operated to be pulled up at the same time, a situation (mixed oil) in which oils of different oil types are simultaneously supplied can be prevented.

When the main valve 36 is opened, the high octane gasoline in the oil storage tank 6 flows through the oil supply pipe 5, the pump 8, the flow meter 10, the oil supply hose 11, and the oil supply nozzle 12, and is supplied to the oil supply port of the automobile from the discharge pipe 33. Is done.
Here, by visually observing the sight glass 34, it can be confirmed that a desired oil type is supplied.

  In FIG. 6 again, when a flow signal is input from the pulse transmitter 9 of the flow meter 10 (YES in ST8), the fuel supply control device 22 counts the amount of fuel supply and displays it on the display 24 (ST9).

When the tank is full and the opening 50 is closed by the supplied oil, the negative pressure generated in the negative pressure generating portion 51 is transmitted to the upper chamber 48 of the diaphragm 47, and the diaphragm 47 and the pin 53 rise against the spring 52. To do. When the pin 53 is raised, the locking by the locking ball 57 is released, and the support shaft 55 is lowered against the spring 56.
When the support shaft 55 and the support shaft 59 are lowered, the lever 39 does not push up the valve shaft 38 and the main valve 36 is closed. When the main valve 36 is closed and the hydraulic pressure disappears, the check valve 40 is also closed. Then, the oil in the discharge pipe 33 flows down into the oil filler opening.

Thus, for example, even when the lever 39 is pulled up, the main valve 36 is automatically closed and the fuel supply is stopped when the tank is full, so that the risk of oil overflowing from the oil supply port can be prevented.
Here, when the check valve 40 is closed, the oil in the discharge pipe 33 flows into the oil filler opening. For this reason, no oil remains in the discharge pipe 33, so that even if different oil types are continuously supplied, the oil does not mix.

When refueling is finished and the refueling nozzle 12 is hung on the nozzle hook 20, an off signal is input from the nozzle switch 21 to the refueling control device 22 (YES in ST10).
The oil supply control device 22 stops the motor 7 and outputs the oil supply data (ST11).
The POS 25 to which this refueling data has been input (YES in ST12 in POS) stores the refueling data as management data and outputs the refueling data to the data input / output device 23 (ST13).
Refueling data is input to the data input / output device 23 (YES in ST14 in the data input / output device), a refueling slip is issued (ST15), and settlement is performed based on the refueling slip.

In the above-described embodiment, the present invention is applied to a fueling device having a POS, but the present invention can also be applied to a fueling device having no POS.
Based on the flowchart of FIG. 8, the operation when the present invention is applied to a fueling device without a POS will be described.

When a person who supplies oil operates the data input / output device 23 to specify a desired oil type (for example, high octane gasoline) (ST21 in FIG. 8), an oil type data signal of the specified oil type is supplied to the oil supply control device 22. (ST22).
The oil supply control device 22 stores the oil supply system 3 (see FIG. 1) of the designated oil type (for example, high octane gasoline) as being drivable (ST23 in the oil supply mechanism in FIG. 8).

  When a person who refuels removes the refueling nozzle 12 from the nozzle hook 20 and an ON signal is input from the nozzle switch 21 to the refueling control apparatus 22 (ST24), the refueling control apparatus 22 displays the previous time displayed on the display 24. The oil supply amount display is returned to zero and the motor 7 is driven (ST25).

  As described with reference to FIG. 6, the discharge pipe 33 of the fueling nozzle 12 is inserted into the fueling port of the automobile, and the main valve 36 is opened for fueling. When the flow rate signal is input from the pulse transmitter 9 of the flow meter 10 to the fuel supply control device 22 by being supplied with fuel (ST26 is YES), the fuel supply control device 22 counts the amount of fuel supply and displays it on the display 24. (ST27).

When refueling ends, the refueling nozzle 12 is hung on the nozzle hook 20 and an off signal is input from the nozzle switch 21 to the refueling control device 22 (YES in ST28), the refueling control device 22 stops the motor 7 and refuels data. Is output (ST29).
The oil supply data output from the oil supply control device 22 is input to the data input / output device 23 (ST30 in the data input / output device of FIG. 8), an oil supply slip is issued (ST31), and settlement is performed based on the oil supply slip. .

The illustrated embodiment is merely an example, and is not intended to limit the technical scope of the present invention.
For example, in the illustrated embodiment, the oil supply device of two oil types has been described, but it is also possible to configure so that oil of three or more oil types can be supplied. When three or more oil types can be supplied, the same number of oil supply systems as the number of oil types that can be supplied are provided in the housing 2 of the oil supply device 1, and the same number as the number of oil types is provided in the main body 26 of the oil supply nozzle 12. The valve mechanism is provided.
