Description

Oil supply device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lubrication apparatus capable of lubricating a desired oil type selected from plural kinds of fuel oils from one lubrication nozzle in a lubrication apparatus for lubricating plural kinds of fuel oil in an automobile.

In a gas station, a plurality of oil supply systems are accommodated in a housing of the oil supply device so as to correspond to automobiles of various fuels, and oil supply nozzles are provided for each oil supply hose of each oil supply system. As such, when the oil supply nozzles are provided for each oil supply system, the cost of the oil supply device is increased at a high rate, and the oil supply nozzles need to be selected for each oil type, thereby reducing work efficiency.

In addition, since the oil supply hoses are provided in the oil supply device for each oil type, the oil supply hoses are located in front of the display of the operation unit and the indicator of the data input / output device, which hinders the operation and display or the degree of freedom of the layout of the device.

The present applicant has proposed a lubrication device in which a plurality of lubrication systems are stored in a housing, the lubrication pipes of each lubrication system are connected to one lubrication hose, and a lubrication nozzle is provided in the lubrication hose (see Patent Document 1).

Although the related art related to the proposal is valid, there is an unreasonable point of lubricating oil by discharging oil in the lubrication hose and the lubrication nozzle when lubricating other types of oil.

The amount of oil in the lubrication hose and the lubrication nozzle is large, about 1.2 L, and the settlement of the mixed amount is unclear, which is unpleasant for the customer.

Therefore, if the oil quality is different, such as diesel, it is a cause of engine trouble and is dangerous.

For this reason, a lubrication device has been proposed in which a plurality of lubrication systems are stored in a housing, and a lubrication hose of each lubrication system is connected to one lubrication nozzle (see Patent Document 2).

Although the related oil supply apparatus (oil supply apparatus of patent document 2) is effective, mixing of the oil in the oil supply nozzle in the case of refueling other types of oil is not eliminated.

Although the amount of oil in the lubrication nozzle is small, about 0.2L, if the oil quality is different, such as diesel, even a small amount may cause an engine trouble, which is dangerous.

[Patent Document 2] Japanese Patent Application Laid-open No. Hei 8-53200

The present invention has been proposed in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a lubrication device capable of lubricating a plurality of oil types with one oil supply nozzle.

The present invention accommodates a plurality of oil supply systems 3 and 4 in the housing 2 and connects the oil supply hoses 11 and 19 of each oil supply system 3 and 4 with one oil supply nozzle 12. In the oil supply device 1 for driving and supplying oil of the oil type system selected by the data input / output device 23, a plurality of valve mechanisms 27 and 28 are assembled in the main body 26 of the oil supply nozzle 12. The inlets 29 and 30 of the valve mechanisms 27 and 28 are connected to the oil supply hoses 11 and 19 of the oil supply systems 3 and 4, respectively, and the outlets of the valve mechanisms 27 and 28 31 and 32 are connected to one discharge pipe 33 via check valves 40 and 63.

Thus, the valve mechanisms 27 and 28 in the main body 26 of the oil supply nozzle 12 described above include the main valves 36 and 60, the levers 39 and 62 which open the main valves 36 and 60, And a mechanism for supporting and releasing the hinge shafts 59 of the levers 39 and 62, which mechanisms hold the hinge shafts 59 of the levers 39 and 62 of the oil supply system 3 and 4 driven. Thus, the levers 39 and 62 of the valve mechanisms 27 and 28 are provided adjacent to each other.

Moreover, the side glass window 34 is provided in each valve mechanism 27 and 28 in the main body 26 of the oil supply nozzle 12 demonstrated previously.

According to this invention, it has the following outstanding effects.

1. Since a single oil supply nozzle can supply oil selectively without mixing a plurality of oil types, it is possible to provide a fuel supply device with low cost and good operability.

2. Since a plurality of valve mechanisms are put in the oil supply nozzle, and the outlet of each valve mechanism is connected to one discharge pipe through a check valve, there is a risk that irrationality may occur even if oil is continuously supplied without different mixtures. none.

3. The mechanism for supporting and releasing the hinge axis of the lever that opens the main valve of the valve mechanism in the oil supply nozzle only supports the hinge axis of the lever of the oil supply system so that the valve does not open when the lever of another oil type is pulled. Oil is never lubricated.

4. Since the levers of the valve mechanisms are provided adjacent to each other, all the levers can be pulled at once and the operability is good.

5. Since each valve mechanism is provided with a side glass window, oil type being lubricated can be seen visually, and customer's trust can be obtained.

EMBODIMENT OF THE INVENTION Below, with reference to drawings, embodiment of this invention is described.

1 is a front view of the oil supply apparatus of the present invention, in which two oil supply systems 3 and 4 are incorporated in the lower part of the housing 2 of the oil supply apparatus 1.

The oil supply pipe 5 of the oil supply system 3 of one side is connected to the oil storage tank 6 of high octane gasoline, for example. The oil supply pipe 5 is provided with a pump 8 driven by a motor 7 and a flow meter 10 having a flow rate pulse transmitter 9 on the way, and the oil supply nozzle 12 is supplied through the oil supply hose 11. Connected.

The oil supply pipe 13 of the other oil supply system 4 is connected to the oil storage tank 14 of a normal gasoline, for example. The oil supply pipe 13 is provided with a pump 16 driven by the motor 15 and a flow meter 18 having a flow rate pulse transmitter 17 connected to the oil supply nozzle 12 through the oil supply hose 19. It is.

The oil supply nozzle 12 is configured to be hung on the nozzle hanger 20, and the nozzle hanger 20 is provided with a nozzle switch 21.

In the upper part of the housing 2, the oil supply control device 22, the data input-output device 23, and the indicator 24 which displays the oil supply amount are provided. Here, the data input / output device 23 is configured to input oil type, flow rate, and the like, and to issue a fuel supply slip.

The oil supply control device 22 receives an ON.OFF signal from the nozzle switch 21 and a flow rate signal from the flow rate pulse generators 9 and 17 of the flow meters 10 and 18.

On the other hand, the driving signal for the motors 7 and 15 for driving the pumps 8 and 16 is sent from the oil supply control device 22, and the oil supply amount display signal is sent to the indicator 24.

The oil supply control device 22 and the data input / output device 23 are configured to exchange oil supply data with the POS 25 installed in an office or the like, and to manage the oil supply data in the POS 25.

2 is a perspective view of the oil supply nozzle.

The main body 26 of the oil supply nozzle 12 has two valve mechanisms 27 and 28.

A high octane gasoline lubrication hose 11 is connected to the inlet port 29 of the valve mechanism 27 on one side. The oil supply hose 19 of ordinary gasoline is connected to the inlet port 30 of the valve mechanism 28 on the other side.

Outlets 31 and 32 of the two valve mechanisms 27 and 28 are connected to one discharge pipe 33.

Reference numeral 34 in Fig. 2 is a side glass window, which is provided on the side surfaces of the valve mechanisms 27 and 28 to show the oil species being discharged.

Here, the position of the side glass window 34 is not limited to the side surface of the valve mechanism 27 (28), but can also be provided in the upper part of the valve mechanism 27 (28).

3 shows the valve mechanism 27 on one side of the oil supply nozzle in cross section.

As described above with reference to FIG. 2, a high octane gasoline lubrication hose 11 is connected to the inlet port 29 of the valve mechanism 27, and the outlet port 31 is connected to the discharge pipe 33.

The main valve 36 is provided in the flow path 35 of the valve mechanism 27.

The main valve 36 applies a force in the direction of closing the valve in the spring 37.

The valve 36 is opened by pushing the valve rod 38 off the lever 39. The check valve 40 is provided in the outlet 31 of the valve mechanism 27.

The check valve 40 exerts a force in the valve closing direction by the spring 41, the valve is opened by the hydraulic pressure discharged.

The mechanism for supporting and releasing the point of the lever 39 which opens the main valve 36 is demonstrated with reference to FIG.

In FIG. 3, the upper chamber 43 of the first diaphragm 42 communicates with the fluid passage 35 via the fluid passage 44. The diaphragm 42 is forced by the spring 45 in the upward direction. Thus, the pin 46 fixed to the diaphragm 42 protrudes from the upper chamber 48 of the second diaphragm 47.

The upper chamber 48 of the second diaphragm 47 has an opening 50 (open hole) at the outer periphery of the distal end of the discharge pipe 33 via the negative pressure path 49 (path through which negative pressure acts). Here, the region in the middle of the negative pressure passage 49 communicates with the negative pressure generating unit 51 provided in the check valve 40.

The diaphragm 47 is urged in the downward direction by the spring 45 which is weaker than the spring 45. Therefore, the diaphragm 47 has a frame and is engaged with the pin 46 of the diaphragm 42. The tip of the pin 53 fixed to the diaphragm 47 is formed of a conical body 54 and inserted into the support shaft rod 55. The support shaft rod 55 is urged in the direction of rising by the spring 56. The support shaft rod 55 is formed with a hole 58 into which the support ball 57 is inserted, and the lever 39 is connected to the lower end of the support shaft rod 55 by the hinge shaft 59.

Since the valve mechanism 28 on the other side of the oil supply nozzle is also the same mechanism as the valve mechanism 27 described above, detailed description of the structure is omitted.

FIG. 4: shows the relationship between a main valve and a lever in cross section in the two valve mechanisms 27 and 28. As shown in FIG.

The valve rod 38 of the main valve 36 of the valve mechanism 27 is connected to the lever 39, and the valve rod 61 of the main valve 60 of the valve mechanism 28 is connected to the lever 62.

The levers 39 and 62 are provided in close proximity, but are constituted by separate bodies.

Thus, the person who is lubricating can put his / her fingers on the levers 39 and 62 in both directions, and simultaneously push and push the levers 39 and 62 in both directions.

However, as described later, the levers 39 and 62, which are pushed in the form of simultaneously pulling up, are lifted up only on one side (movable upward), but not on the other side (not moved upward).

FIG. 5: shows the check valve provided in the outlet port in two valve mechanisms 27 and 28 in cross section.

The outlet side of the check valve 40 provided at the outlet 31 of the valve mechanism 27 and the outlet side of the check valve 63 provided at the outlet 32 of the valve mechanism 28 are connected to one discharge pipe 33. It is.

Next, the operation of the oil supply apparatus of the present invention will be described based on the flowchart of FIG. 6. When the oil feeder operates the data input / output device 23 to designate a desired oil type, for example, high octane gasoline (ST1 is YES), the designated oil kind data is output to the POS 25 (ST2).

The POS 25 into which the oil type data is input (ST3 is YES in the POS of FIG. 6) and a signal for driving a motor (for example, a motor 7) for driving a pump of the specified oil type (eg, pump 8). Output to the oil supply control device 22 (ST4). Thus, the oil supply control device 22 stores the driving permission signal of the motor 7, for example (ST5).

When the oil supply nozzle 12 is removed from the nozzle hanger 20 and the ON signal is input to the oil supply control device 22 by the nozzle switch 21 (ST6 is YES), the oil supply control device 22 displays the indicator 24. The previous oil supply flow rate indication shown in FIG. 9 is returned to zero and the motor 7 is driven (ST7).

In this state, the driver or the person who performs the lubrication operation inserts the discharge pipe 33 of the lubrication nozzle 12 into the lubrication port of the vehicle, simultaneously presses the levers 39 and 62 in the form of pulling up the lubrication, and supplies the lubrication. It starts.

5 and 7, when the pump 8 is driven so that the pressure of the liquid is applied to the upper chamber 43 (FIG. 5) through the flow passage 35 and the fluid passage 44, the high octane gasoline side In the valve mechanism 27, 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 support ball 57 is pushed into the hole 58 by the conical body portion 54 to move, and the support shaft rod 55 is locked (wedge action). Fixed as one body).

When the lever 39 is pulled while the support shaft bar 55 is fixed, the lever 39 is connected to the support shaft bar 55 by the hinge shaft 59 to move the valve 38 in the direction in which the valve 38 is pushed up. Thus, when the valve rod 38 is pushed upward, the main valve 36 is opened against the spring 37 (ascending with compression) (Fig. 7).

On the other hand, in the regular (usually) gasoline supply system 28 in which the pump 16 is not driven, hydraulic pressure does not work, and the valve mechanism 28 is in the state shown in FIG. 3, and the support shaft rod 55 is supported. It is not fixed by the ball 57. In this state, even if the lever 62 is pulled, the support shaft rod 55 only descends while compressing the spring 56, thereby preventing the valve rod 61 from being pushed upward. none.

In this way, the main valve 60 does not open even when the lever 62 is pulled in the valve mechanism 28 to which the hydraulic pressure is not applied. Therefore, even when the levers 39 and 62 are operated to pull at the same time, it is possible to prevent a situation (mixing) in which oils of different oil types are lubricated at the same time.

By opening the main valve 36, the high octane gasoline in the oil storage tank 6 flows through the oil supply pipe 5, the pump 8, the oil supply amount 10, the oil supply hose 11, and the oil supply nozzle 12. Oil is supplied from the discharge pipe 33 to the oil supply port of the vehicle.

By making it look here through the side glass window 34, it can be confirmed that the desired oil type is being lubricated.

6 again, when the flow signal is inputted from the pulse signal device 9 of the flow meter 10 (ST8 is YES), the oil supply control device 22 counts the oil supply amount and displays it on the display 24 (ST9). .

 When the oil is full and the opening 50 is closed by the lubricated oil, the negative pressure generated in the negative pressure generating unit 51 is transmitted to the upper chamber 48 of the diaphragm 47, and the diaphragm 47 is compressed while compressing the spring 52. ) And the pin 53 are raised.

When the pin 53 is raised, the pinching state by the support ball 57 is released, and the support shaft bar 55 is lowered against the spring 56.

When the support shaft bar 55 and the hinge shaft 59 are lowered, the lever 39 is not pressurized to push up the valve rod 38 so that the main valve 36 is closed. When the main valve 36 is closed and the hydraulic pressure is lost, the check valve 40 is also closed. Thus, the oil in the discharge pipe 33 flows into the oil inlet.

In this manner, for example, even when the lever 39 is pulled up, if the oil is full, the main valve 36 is automatically closed to stop the oil supply, thereby preventing the oil from overflowing from the oil inlet.

When the check valve 40 is closed here, the oil in the discharge pipe 33 flows into the oil supply port. Therefore, since oil in the discharge pipe 33 does not remain, even if it refuels another kind of oil continuously, it is not mixed (other oil is mixed and supplied).

When lubrication is completed and the lubrication nozzle 12 is hooked on the nozzle hanger 20, the OFF signal is input from the nozzle switch 21 to the lubrication control device 22 (ST10 is YES).

The oil supply control device 22 stops the motor 7 and outputs oil supply data (ST11).

The POS 25 into which the oil supply data has been input (ST12 is YES in the POS) stores the oil supply data as management data, and outputs the oil supply data to the data input / output device 23 (ST13).

The lubrication data is input to the data input / output device 23 (ST14 is YES in the data input / output device), a lubrication slip is issued (ST15), and settlement is performed based on the lubrication slip.

Although the embodiment described above applies the present invention to an oil supply apparatus having a POS, the present invention can also be applied to an oil supply apparatus without a POS.

Based on the flowchart of FIG. 8, the operation | movement at the time of applying this invention to the oil supply apparatus without POS is demonstrated.

When the oil feeder operates the data input / output device 23 and designates the desired oil type (for example, high octane gasoline) (ST21 in FIG. 8), the oil type data signal of the specified oil type is output 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) so as to be able to be driven (ST23 in the oil supply mechanism of FIG. 8).

When the lubricator removes the lubrication nozzle 12 from the nozzle hanger 20 and the ON signal is inputted to the lubrication control device 22 by the nozzle switch 21 (ST24), the lubrication control device 22 displays the indicator 24. The previous oil supply flow rate display indicated by) is returned to zero, and the motor 7 is driven (ST25).

As described with reference to FIG. 6, the discharge pipe 33 of the oil supply nozzle 12 is inserted into the oil supply port of the vehicle, and the main valve 36 is opened to supply oil. When the flow rate signal is inputted to the oil supply control device 22 by the pulse generator 9 of the flowmeter 10 by refueling (ST26 is YES), the oil supply control device 22 counts the oil supply amount to the indicator 24. (ST27).

When lubrication is finished and the oil supply nozzle 12 is hooked to the nozzle hanger 20 and the ON signal is input from the nozzle switch 21 to the oil supply control device 22 (ST28 is YES), the oil supply control device 22 is connected to the motor 7. ) Is stopped and lubrication data is output (ST29).

The lubrication data output from the lubrication control device 22 is input to the data input / output device 23 (ST30 in the data input / output device of FIG. 8), issue a lubrication slip (ST31), and perform settlement based on the lubrication slip. All.

The illustrated embodiment is illustrative only and adds that the description is not intended to limit the technical scope of the present invention.

For example, although the oil lubrication apparatus of two types was demonstrated in the illustrated example, it is also possible to comprise three or more types of oil supply together. When three or more types of oil can be refueled together, the same number of oil supply systems as the number of oil types that can be supplied together are provided in the housing 2 of the oil supply device 1, and the oil type water is supplied to the main body 26 of the oil supply nozzle 12. The valve mechanism of the same type will be installed.
