Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system in which a person refueling (customer) himself/herself operates a refueling machine to refuel, that is, a refueling apparatus suitable for so-called self-service.

Recently, there has been an increasing demand for this type of refueling device, but since the person performing the refueling operation is an amateur who is not familiar with the operation, it is necessary to simplify the operation and prevent danger. For example, car fuel fillers are installed in different locations on the car body depending on the type of car, but it is desirable to have a high degree of freedom in where the car stops in relation to the filler, and the display for the amount of refueling and the amount charged should be set at the customer's discretion. It is necessary to make sure that it is not mistaken and is located in an easily visible position.

The present invention proposes a refueling device that can meet the above-mentioned demands.

That is, in the refueling system of the present invention, a plurality of islands are installed in parallel, separated by a stopping space for only one vehicle with the expected maximum vehicle body width, and a refueling pump, a flow meter, and the like are installed on one of the adjacent islands. a first branch pipe connected to the secondary side of the flowmeter;
a first refueling hose connected to the branch pipe;
A first refueling nozzle connected to the tip of the refueling hose, a first nozzle case to which the first refueling nozzle is attached and removed, and a first refueling nozzle installed inside the first nozzle case to connect the first refueling nozzle to the first nozzle case. a first nozzle switch that generates and extinguishes a nozzle signal depending on whether the nozzle is connected or disconnected; and a first nozzle switch that supports the first nozzle case.
A support tower is provided, and a second support tower connected to the secondary side of the flow meter is provided on the other adjacent island.
A branch pipe, a second refueling hose connected to the second branch pipe, a second refueling nozzle connected to the tip of the second refueling hose, and a second nozzle case for hooking and removing the second refueling nozzle. and a second nozzle switch that is installed inside the second nozzle case and generates and extinguishes a nozzle signal in response to the second refueling nozzle being connected to and removed from the second nozzle case, and a second support that supports the second nozzle case. A display for the amount of oil measured by the flow meter is attached to the front side of one of the adjacent islands in the vehicle approach direction, and the display surface of this display is shown from the direction facing the approaching vehicle to the other island. It is arranged slightly diagonally toward the island side.

When a car is stopped between a pair of adjacent islands and refueled using a refueling nozzle on a support tower on either island, the amount of refueling is displayed on a display at the front end of the island. In this case, the refueling nozzle located on the island on the side of the vehicle where the refueling port is located can be used, making refueling easier, and since the display is located in front of the island, the display is easy to see.

The illustrated embodiment will be described in detail below.

In the figure, 1 is the site of a gas station adjacent to the road 2, 3 is the gas station building, and I ₁ to I ₅ are islands raised on the surface of the site 1, in the illustrated example, in a direction perpendicular to the road 2. In addition, they are arranged parallel to each other with stopping spaces _A1 to _A4 for only one vehicle having the expected maximum body width.

U ₁ to _{U 4} are pump meter units each including at least a pump P leading to an underground oil storage tank B and a flow meter F, and one pump meter unit having respective oil supply nozzles and an oil supply path leading to each oil supply nozzle. A pair of oil supply systems (hereinafter referred to as delivery units) Da and Db are connected.

That is, oil supply nozzles Na and Nb are connected to the secondary side of the flowmeter of each unit _U1 to _U4 via branch pipes Ta and Tb and hoses Ha and Hb. Ea and Eb are hose Ha, nozzle Na and hose Hb respectively
and the support tower for nozzle Nb.

In the illustrated embodiment, pump meter units U ₁ and U ₂
on island I ₂ and also on pump meter unit U ₃
and U ₄ are installed on the island I ₄ , for example in a recess G of the island, and each pump meter unit U ₁ to
A pair of delivery units Da and Db connected to _U4
One side, Db, is placed on islands I ₂ and I ₄ , and the other side, Da, is placed on islands I ₁ , I ₃ and I _5, respectively.

That is, two delivery units connected to one pump meter unit are arranged on one side of the island adjacent to the island where the pump meter unit is arranged. Therefore, it is possible to refuel a car parked in the space between a pair of adjacent islands using the delivery unit on the island on the side where the refueling port is located.

K is a partition plate interposed between two delivery units Da and Db on islands I ₂ , I ₃ , and I ₄ respectively, which separates each delivery unit on the island from the side opposite to the side on which that unit is placed. This is to prevent it from being used to refuel cars parked nearby.

J is an indicator that displays the amount of refueling by using either of the two delivery units Da and Db connected to one pump meter unit, and the number of units connected to one pump meter unit indicates the amount of refueling by using one of the two delivery units Da and Db. is placed on top. In the illustrated embodiment, there are two pump meter units U ₁ and U ₂ and U ₃ on islands I ₂ and I ₄ respectively.
and U ₄ are placed adjacent to each other.
One indicator may be provided on one island.

The delivery units U ₁ to _{U 4} are arranged on each island on the rear side in the vehicle approach direction (in the illustrated example, on the road side), and the display unit J is arranged on the one island on the rear side in the direction of vehicle approach. The display surface of the display J is arranged at the front end in the direction in which the vehicle enters the vehicle, and the display surface of the display device J is disposed slightly diagonally toward the other island from the direction facing the vehicle. This diagonal arrangement of the display allows the refueling person (or the driver inside the vehicle) to easily see the display no matter which side of the delivery unit is used.

NC is a nozzle case installed in the support tower of each delivery unit, and NS is a nozzle switch installed inside the nozzle case NC.
Generates a nozzle signal according to the connection and disconnection of the nozzle.

CO is a control circuit that performs operations such as returning the display to zero, controlling the pump, and processing flow rate pulses from the flowmeter based on the nozzle signal.

R is a monitoring room set up high inside office building 3.
A supervisor W monitors the refueling work, gives necessary instructions or warnings via a microphone or an interphone (not shown), or controls the refueling device. CB is an operation console installed in monitoring room R for this purpose.
MR is a mirror installed on the side wall, etc., so that blind spots can be seen from the monitoring room.

In the illustrated embodiment, the pump meter unit and the delivery unit are provided separately, but it is of course possible to incorporate the pump meter unit into the housing of the delivery unit.

As described above, according to the present invention, even if the installation position of the fuel filler port is different, the delivery unit on the fuel filler port side can be used, so operation is easy and convenient, and the delivery unit on either side can be used. Since the display is carried out on one common display, it is easy for the customer to check the amount of fuel (price), thereby providing a fueling device suitable for self-service fueling.
