Description

  The present invention relates to a fueling device, and more particularly to a fueling device installed in a self-service fueling station or the like.

  Since gas stations handle flammable liquids such as gasoline and light oil, safety is emphasized. For example, the oil supply hose to which the oil supply nozzle is connected is equipped with a safety joint, and the oil supply hose breaks even if the vehicle starts and excessive force is applied to the oil supply hose with the oil supply nozzle connected to the vehicle oil supply port. Safety joints are separated before the oil hose is prevented from being damaged. Further, the safety valve provided in the safety joint is closed simultaneously with the separation, so that the fuel oil in the fuel supply hose is prevented from being scattered outside the fuel supply device.

  In addition, at a gas station (see Patent Document 1) provided with an outdoor indicator that displays the fueling status of each fueling device, an employee frequently monitors the fueling status of each fueling device by monitoring the outdoor indicator. In addition to efficiently performing the refueling operation, abnormalities in each refueling device are quickly discovered and the safety within the refueling station is kept high.

According to the present invention, the oil supply nozzle is removed from the nozzle hook, but the oil supply nozzle is in a state where no oil supply is made, that is, by notifying the customer that the oil supply is interrupted. It is possible to prevent the customer from starting the vehicle accidentally while inserting the fuel filler nozzle into the fuel filler port of the vehicle. Moreover, since the customer's attention can be directed to the display device by performing this notification, it is possible to prompt the customer who has already supplied a predetermined amount of oil to be additionally supplied (additional oil supply).

  In the fueling device, the notification unit may include a display unit that notifies by light or may include a speaker that notifies by voice. This makes it possible for the customer to recognize that refueling has been interrupted not only when the customer is near the vehicle but also when the customer is away from the vehicle.

  Further, the notification means can change the notification method according to the duration of the state in which the fueling nozzle is removed from the nozzle hook but the fueling nozzle is not fueled. Thereby, it is possible to make the customer recognize that the state where the refueling is interrupted continues for a long time, and strongly urge the customer to continue or end the refueling operation.

  On the other hand, when refueling is not performed after the refueling of the amount set in step S1 is completed (step S9; No), or when the flow rate pulse transmitter does not turn on because the customer does not pull the refueling lever in step S6. (Step S6; No), the display unit 3a of the alarm device 3 is lit yellow (Step S10). In this state, the customer does not return the fueling nozzle 6 to the nozzle hook 7 (Step S11; No), the fueling lever is not pulled (Step S12; No), and when this state has elapsed for a predetermined time t1 (Step S13; Yes), a notification is made. An intermittent sound is emitted from the speaker 3b of the device 3 (step S14).

  Furthermore, when the same state (step S15; No, step S16; No) elapses for a predetermined time t2 (however, “t2> t1”) (step S17; Yes), the display unit 3a of the notification device 3 turns red. Lights up (step S18). Further, when the same state (step S19; No, step S20; No) elapses for a predetermined time t3 (provided that “t3> t2”) (step S21; Yes), a continuous sound is output from the speaker 3b of the alarm device 3. It is emitted (step S22). Whether the fueling nozzle 6 is hung on the nozzle hook 7 and the nozzle switch is turned off (step S23; Yes), or the fueling lever is pulled and the flow rate pulse transmitter is turned on (step S24; Yes). Unless applicable, the state of step S22 continues (step S24; No).

  On the other hand, in step S12, S16, S20, and S24, when the fueling lever is pulled and fueling is performed (step S12; Yes, step S16; Yes, step S20; Yes, step S24; Yes), the display 8 Is displayed, the indicator 3a of the alarm 3 is lit in blue, and the refueling lamp 4 is lit (step S7). Moreover, when the intermittent sound or the continuous sound is emitted from the speaker 3b of the alarm device 3, the sound stops (step S25).

  In steps S11, S15, S19, and S23, when the oil supply nozzle 6 is hooked on the nozzle hook 7 and the nozzle switch is turned OFF (step S11; Yes, step S15; Yes, step S19; Yes, step S23; Yes). The fuel pump is turned off, and the notification by the alarm device 3 (lighting of the display unit 3a, sound from the speaker 3b) is stopped (step S26). As a result, a refueling end output is made in the refueling device 1 and an end signal is transmitted to the POS (step S27), which is received at the POS and a refueling end input is made (step S33; Yes). Then, a slip is issued at the POS (step S34), and a series of refueling operations ends.

  As described above, according to the present embodiment, the customer is notified that the fueling nozzle 6 is detached from the nozzle hook 7 but is not fueled from the fueling nozzle 6, that is, the fueling is interrupted. Thus, it is possible to prompt the user to put the fueling nozzle 6 on the nozzle hook 7 and prevent the customer from starting the vehicle 21 by mistake while the fueling nozzle 6 is inserted into the fueling port 21a of the vehicle 21.

However, by performing the above notification, the customer's attention can be directed to the display unit 8, and refueling can be promoted.

  Further, the refueling operation is performed or terminated for a customer who does not refuel after removing the refueling nozzle 6 from the nozzle hook 7 or a customer who does not refuel after completing the set amount of refueling or does not end the refueling operation. Can be encouraged.

  Note that various sounds can be used as the sound emitted from the speaker 3b as long as it appeals to the customer's hearing, such as electronic sound, voice, and music.

  In addition, the display color on the display unit 3a and the sound emitted from the speaker 3b were changed with the passage of time during which refueling was interrupted. Thus, the customer is gradually strengthened in the ability to recognize the notification. Is preferred. For example, it is preferable to change the light emitted from the display unit 3a from a small wavelength to a large wavelength within the visible range, or to increase the emission intensity. It is also preferable to increase the volume emitted from the speaker 3b. It is preferable that the timing for changing the notification method is determined in consideration of the strength of the force that makes the customer recognize the notification, the discomfort that the notification gives to a third party, the duration of refueling interruption, the environment of the gas station, and the like.

  In the above-described embodiment, the fueling device 1 is installed in the self-service type gas station 11, but it can also be installed in a gas station where the employees of the gas station perform a fueling operation.
