Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel supply device for supplying fuel oil to an automobile, and more particularly to a fuel supply device for preventing refueling of a wrong type of oil.

[0002]

2. Description of the Related Art Fuel oil for automobiles includes gasoline and light oil. If different fuel oils are supplied to the vehicle for driving, the engine may break down, resulting in an accident or fire. Therefore, the present applicant has proposed in JP-A-4-87995 a lubricating apparatus in which a sensor for reading an oil type indicating member attached to a cap is provided on a cap mounting base to prevent refueling of an incorrect oil type. Although this is effective, the oil type indicator member that is read optically becomes dirty, and the oil type indicator member that is read magnetically deteriorates the magnetism due to long-term use.
Incorrect oil type judgment may occur.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a lubricating apparatus which does not cause an erroneous determination of oil type even if it is soiled, and which can accurately determine the oil type even after long-term use. is there.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention comprises a weighing machine having a plurality of lubrication systems, and a cap table attached to the weighing machine, wherein a transponder is attached to the cap. In a vehicle refueling device, a transmitter / receiver is provided on the cap mounting table, and a control device that receives an oil type signal from the transmitter / receiver and sets the oil supply system of the corresponding oil type to a movable state is provided. There is no problem, the oil type can be accurately determined even after long-term use, and lubrication of the wrong oil type can be prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1, 2, and 3, a refueling device 2 is provided on an island 1 provided on a site of a refueling station, and each refueling device 2 is connected to a POS 4 in an office 3. The refueling device 2 is composed of a weighing machine 5 and a cap table 6 laid on the weighing machine 5. The weighing machine 5 has a plurality of oil types, such as a gasoline refueling system 7.
A light oil supply system 8 is incorporated, and a cap receiver 6 is provided with a transmitter / receiver 9.

[0006] A pump 12 driven by a motor 11 and a flow meter 14 provided with a flow pulse transmitter 13 are interposed in an oil supply pipe 10 of a gasoline oil supply system 7 connected to an oil storage tank (not shown). . A refueling hose 15 is connected to a tip of the refueling pipe 10, and a refueling nozzle 16 is attached to a tip of the refueling hose 15.
Is provided with a nozzle switch 18. The light oil supply system 8 is also the same as the gasoline supply system 7, and a description thereof will be omitted.

On the other hand, a transponder 22 for transmitting customer data such as an oil type and a customer number is attached to a cap 21 of a filler port 20 of a car 19 of the customer. When the cap 21 is placed on the cap table 6, data transmission and reception are performed between the transmitter / receiver 9 and the transponder 22.

[0008] To the control device 23 for controlling refueling, customer data is input from the transmitter / receiver 9, a nozzle disconnection signal is input from the nozzle switch 18, and a flow rate pulse signal is input from the flow rate pulse transmitter 13. Then, the control device 23 outputs a drive signal to the motor 11, outputs a refueling amount display signal to the display 24, and outputs a notification signal to the alarm 25. Further, the control device 23 exchanges data with the POS 4 in the office 3 via the signal line 26.

Next, the refueling operation will be described with reference to the flowchart of FIG. The transmitter / receiver 9 provided on the cap table 6 includes:
Electromagnetic waves for power generation and transmission data are output at regular intervals. A car that has come to refuel, for example, a car 19 using gasoline as fuel, stops in front of the refueling device 2, places a cap 21 removed from the refueling port 20 of the car 19 on the cap table 6 of the refueling device 2, and attaches the cap 21. When the transponder 22 receives the electromagnetic wave and the transmission data from the transmitter / receiver 9, it transmits customer data such as oil type and customer number.

The control device 23 which has received the customer data (ST1 in FIG. 4) outputs the customer data to the POS 4 (ST2 in FIG. 4). Then, the POS 4 checks the contents of the customer data, and outputs a refueling permission signal if it is normal. The control device 23 that has received this refueling permission signal (ST3 in FIG. 4) sets the oil supply system 7 for the corresponding oil type and gasoline to a movable state (ST4 in FIG. 4).

When the fuel supply nozzle 16 is removed from the nozzle hanger 17 of the gasoline refueling system 7 which has become movable as described above, an ON signal is output from the nozzle switch 18 to the control device 23.
(ST5 in FIG. 4), the previous refueling amount displayed on the display 24 is reset to zero, and a drive signal is output to the motor 11 (ST6 in FIG. 4). Then, the pump 12 is driven by the motor 11.

The fuel nozzle 16 is connected to a fuel port 20 of an automobile 19.
Is inserted and the refueling is started, the flow rate pulse is input from the flow rate pulse transmitter 13 of the flow meter 14 to the control device 23 and calculated, and the refueling amount is displayed on the display meter 24. When the refueling of the desired amount is completed and the refueling nozzle 16 is hung on the nozzle hanger 17, an OFF signal is input from the nozzle switch 18 to the control device 23 (ST 7 in FIG. 4), and the control device 23
The drive signal to the POS 4, output the refueling data to the POS 4, and output the operation signal to the alarm 25 (ST in FIG. 4).
8). Then, the annunciator 25 gives an alert such as "Please do not forget the cap. Please pay at the office."
Since the notification is made in this manner, it is unnecessary to forget to close the cap of the fuel filler of the automobile.

The POS 4 that has received the refueling data issues a refueling slip and manages the refueling data. Then, the customer makes a payment in the office 3.

If the result of the check of the contents of the customer data by the POS 4 is abnormal, a refueling impossible signal is inputted (ST9 in FIG. 4). Then, a notification signal is output to the notification device 25 (ST10 in FIG. 4), and the notification device 25 notifies "Please come to the office". The refueling staff explains the cause of non-refueling, prevents improper refueling, and prevents trouble with customers.
