2. Description of the Related Art In a conventional refueling facility, when a refueling vehicle enters, a refueling worker performs a predetermined operation on a refueling device to refuel the refueling vehicle. When refueling is completed, a system is employed in which a refueling worker bills a customer, receives a refueling fee, and refunds as necessary. By the way, in order to reduce the number of unmanned or labor-saving refueling workers, so-called self-service in which the customer performs refueling work on behalf of the refueling workers in the above-mentioned conventional refueling equipment has been studied. In the case of self-service refueling, a post-payment method in which a customer comes to the office to pay after refueling, or the customer asks the office to determine the amount of refueling based on refueling schedule information before refueling, and refueling fee If a change is made based on actual refueling information, any of the prepayment methods of returning it at the office will be adopted.

[0003]

However, if the above-mentioned post-payment system is employed, there is a possibility that the vehicle will escape without paying the refueling fee, so it is preferable to employ the pre-payment system. In the prepayment method, the customer may have to make two round trips to and from the office between the prepayment time and the change receipt time, which imposes an extra labor burden on the customer. Therefore, an object of the present invention is to provide a refueling device that can reduce the labor burden on a customer while adopting a security prepaid method.

[0004]

In order to achieve the above object, an oil supply device according to the present invention comprises: an oil supply means for supplying oil to a tank; an oil type detection means for detecting an oil type of an oil liquid in the tank; A refueling amount detecting means for detecting a refuelable oil liquid amount in the tank, an indicator for displaying to a user, a depositing device for receiving a refueling charge, and an oil liquid amount detected by the refueling amount detecting means.

Here, the suction tube 22 is connected to the hose 19.
And is extended to the inside of the airframe 11 and is open to the atmosphere. At an intermediate position in the airframe 11, suction from the oil supply nozzle 20 side to the intake tube 22 and discharge to the oil supply nozzle 20 side are performed. A pump 26 is provided.
An oil type detection sensor 27 that detects an oil type from oil vapor flowing through the intake tube 22 by performing suction from the oil supply nozzle 20 side by the pump 26 on the oil supply nozzle 20 side of the pump 26 in the machine body 11, Refueling amount detection for changing the amount of air in the fuel tank of the vehicle sealed by the closing means 25 and detecting the amount of space in the fuel tank, that is, the amount of oil liquid that can be supplied to the fuel tank, from the amount of change and the change in pressure. And a sensor 28 (the refueling amount detection sensor 2).
No. 8 is disclosed in JP-A-58-99399).

At a position facing the outside of the machine body 11, there is provided a nozzle holder 30 for detachably supporting the oil supply nozzle 20. The nozzle holder 30 has the oil supply nozzle 20 attached to and detached from the nozzle holder 30, that is, an oil supply nozzle. A nozzle switch 31 for detecting use / non-use of the nozzle 20 is provided. In addition, at a position facing the outside of the machine body 11, a display 32 which is located near the refueling nozzle 20 and displays a refueling amount or the like.
In addition, an operation guide display 33 for providing a guide display to the user and performing an input operation by the user, and a depositing device 34 for accepting a refueling fee and paying change as necessary are provided.

In addition, a vehicle detection sensor 37 for detecting whether or not the vehicle has stopped at a position where refueling by the refueling device 10 is possible is provided in the passage 36 into which the vehicle for refueling enters. Note that a control section (control means) 38 for controlling the above sections is provided in the body 11.

Next, the contents of control by the control unit 38 will be described with reference to a flowchart shown in FIG. First, the control unit 38 monitors whether the vehicle is detected by the vehicle detection sensor 37 (step S1).
When the vehicle detection sensor 37 does not detect the vehicle,
While it is determined that there is no vehicle, step S1 is repeated to continue the detection state of the vehicle, while the vehicle enters the side passage 36 of the refueling device 10 to refuel the fuel tank and is detected by the vehicle detection sensor 37. It is determined that there is a vehicle, and the user follows the operation of the operation guide display 33 in FIG.
Is displayed on the display unit 41 of the operation guide display 33 to prompt the user to remove the refueling nozzle 20 and insert it into the refueling port of the vehicle (a display example is not shown) (step S2). ).

The control unit 38 determines whether the nozzle switch 31 provided on the nozzle holder 30 has been turned on by removing the refueling nozzle 20, or remains in the OFF state without removing the refueling nozzle 20. Detection (step S
3) If the refueling nozzle 20 is in the OFF state, step S
Return to 2.

On the other hand, when the user removes the refueling nozzle 20 according to the display on the display section 41, the refueling nozzle 20
Is turned on, and the control unit 38 controls the refueling nozzle 2
0 is inserted into the filler hole of the vehicle.
4 (step S4), and returns to step S2 when the fueling nozzle 20 is not inserted into the fueling port of the vehicle.
On the other hand, when the user inserts the refueling nozzle 20 into the refueling port of the vehicle according to the display on the display unit 41, the insertion is detected by the insertion sensor 24, and the control unit 38 controls the refueling nozzle by the locking means 23. 20 is fixed to the filler port of the vehicle (step S5). Here, when locked by the lock means 23, the closing means 25 closes the opening of the fuel filler.

Subsequently, the control unit 38 detects the amount of oil that can be supplied to the fuel tank of the vehicle with the supply amount detection sensor 28 and inputs a signal corresponding to the amount of oil (step S).
6). Next, oil vapor is sucked from the inside of the fuel tank by the pump 26 via the intake tube 22 (step S).
7) The oil type is detected from the oil vapor by the oil type detection sensor 27, and a signal corresponding to the oil type is input (step S).
8).

Next, the control unit 38 controls the operation guide display 33
Are switched as shown in FIG. 3 (step S).
9). Here, the operation guide display 33 has, for example, a touch panel affixed to a predetermined range on its surface, and a signal is output to the control unit 38 for each display position pressed by the user pressing the display position. Then, the control unit 38 can understand what is selected.

In this case, first, the display section 41 is divided into three areas 41a to 41c, and the upper oil type display section 41 is divided into three areas.
"a" is displayed as "regular", "high octane", "light oil", and only the oil type of the oil liquid in the fuel tank detected by the oil type detection sensor 27 is turned on, and the other oil types are not turned on. . Then, the lower part of the oil liquid amount display section 41
b, a display for selecting an oil liquid amount at the time of full tank refueling and fixed amount refueling is performed. That is, the display of "full tank" and the amount of the oil liquid detected by the oil supply amount detection sensor 28 (a predetermined ratio for preventing overflow is already applied) are displayed adjacent to the display, and the full tank oil supply amount is further displayed. For example, among the smaller oil liquid amounts, all the oil liquid amounts “L” obtained by truncating one or less digits are displayed. For example, when the oil amount detected by the oil amount detection sensor 28 is 33.5 L,
"Full 33.5L", "10L", "20L" and "3"
0L "is displayed.

In addition, the money amount display section 41c on the lower side shows
The display for selecting the amount of the refueling price at the time of fixed amount refueling is performed. That is, the amount of the oil liquid detected by the refueling amount detection sensor 28 is multiplied by the unit price of the oil type detected by the oil type detection sensor 27. To display all amounts. For example, if the amount of the oil liquid multiplied by the unit price of the oil type and the amount including tax exceeds 3,000 yen, "1000
"Yen", "2000 yen", and "3000 yen" are displayed. Further, a “contact with clerk” button 42 for contacting the clerk, a “confirm” button 43, and a “start” button 44 are provided below the clerk.

Here, the upper oil type can be selected by pressing the oil other than the lighted one, that is, the oil in the light-off state. When the oil other than the lighted one is pressed, the oil type is pressed. In this case, only the selected oil type is turned on, and the display for selecting the above-described amount at the time of the fixed-amount refueling is set and changed as necessary based on the unit price of the selected oil type. Then, the control unit 38 temporarily stores the initially lit one, and temporarily stores the last pressed one when pressed.

The control unit 38 turns on all of the displays on the oil amount display unit 41b and the amount display unit 41c before selection, and when any one is pressed and selected, the display other than the pressed one is performed. By turning off the light, which one is selected is displayed. In addition,
It is also possible to change the selected one. In this case, by pressing the unlit one to be changed, it is turned on, and the others are turned off. Then, the control unit 38 temporarily stores the last pressed thing.

When all the settings (oil type setting, full tank refueling, fixed quantity refueling, and fixed rate refueling) are completed in this way, the "confirm" button 43 which has been turned off until then is set.
Is lit so as to promote the pressing. Thus, the user presses the “confirm” button 43 after the setting is completed.

The control unit 38 determines whether or not the "confirmation" button 43 has been pressed (step S10). If the "confirmation" button 43 has not been pressed, the control proceeds to step S10.
When the "Confirm" button 43 is pressed as described above, the "Confirm" button 43 is turned off, and it is determined whether or not there is a setting error (step S10). S11). That is, when the oil type that is lit when the “confirmation” button 43 is pressed cannot be mixed with the oil type detected by the oil type detection sensor 27, that is, when the selected oil type is regular or high-octane, it is detected. If the oil type is light oil or vice versa, it is determined that the setting is abnormal, and a notification is provided to the staff by a notification means or the like provided in the office (step S12), and the process returns to step S9.

On the other hand, if there is no setting error, the control unit 38
Is divided from the temporarily stored setting conditions, that is, the set oil type, the set oil amount (if the full tank refueling or the fixed amount refueling is temporarily stored, the set oil amount, and if the fixed amount oil is selected, the amount is divided). The set oil amount to be output) is stored in a memory (step S13). Then, when set with full tank refueling and fixed quantity refueling, multiply the set oil liquid amount by the unit price of the set oil type, furthermore, the amount including tax is included. The required time required for refueling is displayed on the display unit 46, the required time for refueling is calculated from the amount of oil, and displayed on the required time display unit 47, and a signal indicating the amount is output to the depositing device 34 (step S1).
4).

When the amount is displayed on the determined amount display section 46, the user pays the amount to the depositing device 34. Here, in the depositing device 34, the control unit 3
If a larger amount is paid according to the amount output from 8, the change is paid out. When the money is paid, the depositing device 34 outputs to the control unit 38 a signal indicating that the payment is completed.

After step S14, the controller 38 determines whether or not the payment is completed based on the presence or absence of a signal from the depositing device 34 (step S15). If the payment is not completed, the process returns to step S14. On the other hand, when the payment is completed, the "start" button 44 which has been turned off until then is turned on, and it is determined whether the "start" button 44 has been pressed (step S16).
In a state where the button 44 is not pressed, step S1
6 is repeated until the "start" button 44 is pressed.

When the user pays the amount to the depositing device 34, the user presses the "start button" 44 which is lit thereafter. When the "start" button 44 is pressed in this manner, the control is started. The unit 38 turns off the “start” button 44 and starts refueling from the refueling nozzle 20 (step S17). That is, the underground tank of the set oil type is communicated with the pipe 12 and the driving of the oil supply pump 13 by the pump motor 15 is started, so that the oil liquid is discharged from the oil supply nozzle 20 into the fuel tank.

Then, from the start of refueling, the actual refueling amount determined from the signal from the flow rate pulse oscillator 17 is compared with the set oil amount stored in the memory. Is determined, that is, whether or not the set oil liquid amount is actually refueled (step S18). If the set oil liquid amount is not actually refueled, step S18 is repeated. Thus, refueling is continued until the set amount of oil is actually refueled. On the other hand, when the set amount of oil is actually supplied, the pump motor 15 is stopped and the lock by the lock means 23 is released, and the speaker 4 is notified that the supply has been completed.
Guidance is provided by voice from 0 (step S19).

Then, the user withdraws the refueling nozzle 20 from the refueling port of the vehicle, returns the nozzle to the nozzle hook 30, and then moves the vehicle to leave the refueling station. Therefore, the control unit 38 detects whether the nozzle switch 31 provided on the nozzle holder 30 is turned off by returning the refueling nozzle 20, or whether the refueling nozzle 20 is kept off without returning (step S20). If the nozzle switch 31 is on, the process returns to step S20. If the nozzle switch 31 is off, the vehicle detection sensor 3
It is determined whether or not the vehicle is detected in Step 7 (Step S)
21) If the vehicle detection sensor 37 is detecting a vehicle, step S21 is repeated, and when the detection of the vehicle by the vehicle detection sensor 37 is released, it is determined that the vehicle has left.
The data in the memory at the time of refueling this time is erased (step S22) to prepare for the next refueling.

As described above, the control unit 38 determines the amount of the oil liquid that can be supplied by the oil supply amount detection sensor 28 and the oil type that is detected by the oil type detection sensor 27 or the oil amount that is selected and set. Calculate refueling price from oil type and refuel nozzle 2
When displayed on the operation guide display 33 provided near 0, the user, that is, the customer, pays with the depositing device 34 provided near the refueling nozzle 20 according to this display. Then, the control unit 38 determines that the refueling price is
No. 4, the fueling from the fueling nozzle 20 is permitted (that is, the determination in step S15 is YE
S). Thereby, refueling can be started by the refueling nozzle 20. After the start of refueling, when the refueling for the set amount of oil (the amount of oil detected by the refueling amount detection sensor 28 in the case of full refueling) is completed, the control unit 38
Stops the refueling from the refueling nozzle 20.

Therefore, the advance payment is made by the depositing device 34 provided in the vicinity of the refueling nozzle 20 in accordance with the price display of the operation guide display 33 provided in the vicinity of the refueling nozzle 20.
Therefore, there is no need to reciprocate between the office and the disposition position of the refueling nozzle 20, and the burden on the customer can be reduced. In addition, since the amount of oil liquid that can be supplied into the fuel tank is detected by the supply amount detection sensor 28, the set value at the time of prepayment of the supply amount in full tank refueling becomes accurate,
Therefore, a situation in which the actual refueling amount is less than the pre-paid set value and a refund is required, or a situation in which the pre-paid set value is significantly less than the actual possible refueling amount and causes customer dissatisfaction, etc. Can be prevented from occurring.
Furthermore, by adopting the advance payment, even if the hands become dirty during the refueling operation, the payment operation after the refueling operation becomes unnecessary, so that it is possible to prevent the clothes from being soiled. in addition,
In order to accurately detect the amount of oil that can be refueled at the time of full refueling, an auto stop mechanism for detecting the liquid level with the refueling nozzle 20 and stopping refueling is not required, and fine adjustment by the refueling lever is also unnecessary.

As the refueling amount detection sensor 28, a sensor which detects the liquid level and each wall surface of the fuel tank by reflection of ultrasonic waves or the like to detect the amount of oil liquid which can be supplied to the fuel tank can be used. It is.

[0030]

As described in detail above, according to the lubricating device of the present invention, the control means controls the amount of oil that can be supplied and the oil type detected by the oil type detecting means. Then, when the refueling price is calculated and displayed on the display, the customer pays with the depositing device. When the refueling fee is accepted by the depositing device in this way, the control means permits refueling by the refueling means. Thereby, refueling can be started by the refueling means. When the refueling for the oil amount detected by the refueling amount detecting means is completed, the control means stops refueling by the refueling means. Therefore, the advance payment can be made by the depositing device according to the display on the display, so that there is no need to reciprocate between the office and the disposition position of the refueling means, and the labor burden on the customer can be reduced.
In addition, the amount of oil that can be refilled in the tank is detected by the refueling amount detecting means, so that the set value at the time of advance payment of the oil amount becomes accurate, and therefore, the actual amount of refueling becomes smaller than the set value at the time of advance payment, and the refund is made. Can be prevented from occurring, or a situation in which the set value at the time of advance payment is significantly smaller than the actual possible refueling amount and the customer is dissatisfied.
