Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fueling device, and more particularly to a fueling device having a function for preventing a cap from being forgotten to be mounted on a fuel tank of an automobile. 2. Description of the Related Art A cap mounting table provided with a sensor for detecting the presence or absence of a cap of an automobile fuel tank near a refueling device and reading an indication of an oil type attached to the cap is provided. Can be refueled on condition that the oil type matches, and if the cap remains on the cap mounting table at the stage when refueling has been completed, the alarm means is activated to activate the cap. There has been proposed a refueling device configured to notify the user of forgetting to occupy (Japanese Unexamined Patent Publication (Kokai) No. Heisei 9 (1999)).
4-87995). However, it is necessary to always put the cap in a fixed place, and there is a problem that veteran refueling staffs are more troublesome when busy. [0003] The present invention has been made in view of such a problem, and an object of the present invention is to make it possible to refuel according to an advanced work procedure and to provide a cap. An object of the present invention is to provide a new refueling device that can prevent forgetting to close. [0004] In order to solve such a problem, the present invention provides an oil supply pump driven by a pump motor and a flow rate pulse transmission for converting an oil supply amount into a pulse signal and outputting the pulse signal. Flow meter equipped with a device, a refueling nozzle connected to the flow meter via a hose, a nozzle hook provided with a nozzle switch for detecting whether or not the refueling nozzle is engaged, and a pulse signal from the flow pulse transmitter. An automotive fuel tank, comprising: a refueling amount display that displays a count value; and a control device that drives and controls the pump motor and the refueling amount display in response to a nozzle disconnection signal from the nozzle switch. a first alarm that displays a message in characters prompting tightening the cap, the voice

You. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention. FIG. 1 shows an embodiment of the present invention. In the drawing, reference numeral 1 denotes a fueling device main body, and a fueling pump 3 driven by a pump motor 2 to pump fuel oil in an oil storage tank (not shown).
And a flow meter 5 having a flow rate pulse transmitter 4 for measuring the fuel oil from the refueling pump 3 and outputting the measurement result as a flow rate pulse, and supplying the fuel oil pressure-fed through the flow meter 5. An oil supply mechanism comprising an oil supply nozzle 7 received via a hose 6 is provided. Reference numeral 10 denotes an annunciator which is capable of displaying the character "Whether the cap is closed" in a static display and a blinking display, for example, a display plate in which characters are written on a fluorescent screen and illumination means is provided on the back surface. Also, an information display 11 such as a display constituted by a light emitting diode array and an information speaker 12 capable of outputting sound are housed in a housing and provided near the nozzle hook 8. Reference numeral 13 denotes a control device which will be described later. The nozzle switch 9 detects whether or not the fueling nozzle 7 has been disconnected, and the flow rate pulse from the flow rate pulse transmitter 4 is counted and displayed on the fueling quantity display 14 as the fueling quantity. Also, a message prompting the user to attach a cap to the vehicle fuel tank after refueling is output to the alarm 10. FIG. 2 shows an embodiment of the control device 13 described above. Reference numeral 25 denotes a weighing device control device, which resets the counting means 26 when a nozzle disconnection signal is output from the nozzle switch 9. At the same time, the pump motor 2 is operated to allow refueling, and the number of flow pulses output from the flow rate pulse transmitter 4 with the refueling is counted and displayed on the refueling display 14 as the refueling amount. When the refueling is completed and the refueling nozzle 7 is returned to the nozzle hook 8 and a nozzle return signal is input from the nozzle switch 9, the pump motor is stopped, and the alarm 10 is driven to ask “Is the cap closed?” The message is displayed on the notification display 11 by blinking, and the same message is also notified from the notification speaker 12. In the drawings, reference numerals 22, 23, 26, 28
1 shows a driving unit for driving the notification display unit 12, a driving unit for driving the notification loudspeaker 12, a driving unit for driving the pump motor 2, and a driving unit for driving the refueling amount display 14, respectively. Next, the operation of the above-configured apparatus will be described with reference to the flowchart shown in FIG. When the vehicle to be refueled has entered, the cap is removed from the fuel tank and placed on a location such as the refueling device main body 1. Next, when the refueling nozzle 7 is removed to perform refueling and the nozzle switch 9 is turned on (step S1).
I). The weighing machine control means 25 activates the notification display 11 to display "Is the cap closed?", Receives the nozzle removal signal, returns the counting means 26 and the refueling amount display 14 to zero, and sets the pump motor 2 (Step b). When refueling is started in this state, a flow pulse is output from the flow pulse transmitter 4 (step S1).
C). The flow rate pulse is counted by the counting means 26 and displayed on the refueling amount display 14 as the refueling amount (step d). During refueling, the message "Did you close the cap?" Is displayed on the notification display 11, so that attention is paid to closing the cap even during busy hours. When the refueling of a predetermined amount is completed and the nozzle 7 is returned to the nozzle hook 8 and the nozzle switch 9 is turned off (step E), the pump motor 2 is turned off to terminate the refueling operation, and the information display 11 is displayed. The display is switched to a blinking state, a message "Is the cap closed?" Is displayed, and the notification utterance unit 12 also outputs the message as a sound (step F). [0015] The flashing display and the sound further alert the refueler and ensure that the cap is securely fastened to the fuel tank of the vehicle. When a predetermined time, for example, about 10 seconds, elapses (step T), the display of the notification display 11 disappears, and the sound of the notification speaker 12 also stops (step T). In the above-described embodiment, the alarm is arranged near the nozzle hook. However, even if the alarm is provided at another position which is easy to see after the refueling is completed, for example, the upper part of the fueling device main body is provided. It works. According to the present invention as described above ,
Using the signal from the nozzle switch, a message is displayed during refueling.
Be displayed in a static state to reduce annoyance and
Arouse, also point a point in time in the message refueling has been completed
Warning with a blinking display and sound to alert you more strongly
it can.
