Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a weighing display section of a weighing machine in a gas station.

(B) Conventional technology Conventionally, at a gas station, a weighing machine for finely measuring the amount of fuel to be refueled has been installed. Normally, a refueling pipe communicating from an underground tank is led to the ground, The oil suction pump that is connected to the oil suction nozzle can supply oil from the oil supply nozzle, and a flow meter is installed in the middle of the oil suction pump and the oil supply nozzle. It is designed to be displayed on the weighing display section provided on the front and rear surfaces of the machine.

(C) Problems to be solved by the invention However, since the weighing display section provided on such a weighing machine is not provided on the front and rear surfaces of the weighing machine body, it stopped in front of or behind the weighing machine. When refueling a car, the service person at the gas station must go to the rear end of the car to carry out refueling work, and must look at the weighing display section of the weighing machine from an oblique direction. It became difficult and hindered accurate refueling work.

(D) Means for Solving the Problems This invention is a thin, substantially rectangular weighing machine body in which a nozzle engaging portion of an oil supply nozzle is provided on a narrow side surface, and the oil supplying nozzle is detachably attached to the nozzle engaging portion. In addition to being configured to engage, the hose of the nozzle is configured to extend from the side surface of the weighing machine body, and the metering sub-indication is displayed on the upper part of the nozzle engagement part of the refueling nozzle that engages with the narrow side surface of the weighing machine body. The display section is arranged to be digitally displayed, and the main weighing display section is arranged to be digitally displayed on the front surface or the back surface of the weighing machine main body.
Further, a flow meter is connected to an oil suction pump built in the main body of the weighing machine, and a signal is transmitted from the metering control section connected to the flow meter to the main meter display section. Therefore, a metering display section of a weighing machine in a gas station, which is branched from a middle section of the wire connection and is connected to a digital display mechanism of a sub-display section for metering, is provided.

(E) Action / Effect In the present invention, when the vehicle to be refueled stops at the front or rear of the weighing machine at the gas station and is refueled from the refueling nozzle hanging on the side of the weighing machine, The serviceman of the gas station will check the amount of refueling while looking at the main meter display section that digitally displays on the front or back of the weighing machine body.

At this time, the service person will look at the weighing main display section arranged on the front or the back from an angle, so if it is difficult to see it, look at the weighing sub-display section provided on the side surface of the weighing machine main body for accurate weighing. Confirmation can be done.

Therefore, the service person can perform accurate weighing confirmation even in an oblique direction away from the front or back of the weighing machine body.

Moreover, since the metering sub-display part is provided above the nozzle engaging part, the hose of the refueling nozzle does not interfere with the visibility, and the refueling nozzle is engaged with the nozzle engaging part after the refueling work is completed. At that time, the amount of refueling can be clearly confirmed.

Furthermore, at this time, even if the oil dripping from the refueling nozzle flows down from the vicinity of the nozzle engaging portion to the side surface of the weighing machine main body, the metering sub-display portion is arranged above the nozzle engaging portion, so the dripping is performed. There is no risk of oil or the like adhering to the display window surface of the sub-measurement display section, and therefore, there is no possibility of stains on the display window or damage due to chemical changes in the display window material due to oil.

In addition, it is possible to provide the weighing sub-display even if the side surface of the weighing machine body is narrow.

Furthermore, a flowmeter is connected to the oil suction pump built into the main body of the weighing machine, and a signal is transmitted from the measurement control section connected to the flowmeter to the main measurement display section. By connecting to the digital display mechanism of the weighing sub-display by branching from the middle of the wire connection, the same lubrication amount as that displayed on the main measurement display can be digitally displayed. The internal structure of the main body of the weighing machine can be made compact.
