Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to refueling equipment, and particularly to refueling equipment for gas stations.

Generally, a gas station consists of an office building and a refueling service area where multiple refueling equipment are located, and a ceiling structure called a "canopy" is installed above the refueling service area. It is customary to ensure that refueling services are not disrupted even in rainy weather. If the refueling service band is relatively narrow, the canopy can be configured in a cantilevered configuration and supported on the side of the office building, so that vehicle traffic entering and exiting the refueling service band is restricted to the canopy. It is not obstructed by the installation. However, if the refueling service band is widened, the structural weight of the canopy will increase, so this is difficult.

It is difficult to construct the canopy in a cantilevered manner, and therefore it is necessary to provide one or more struts within the refueling service zone to support the canopy. In this case, the above-mentioned support not only becomes an obstacle for vehicles traveling in the refueling service zone, but if an accident such as a vehicle colliding with the support occurs, there is a risk that the canopy itself may be damaged. There are cases where refueling piping is provided inside the canopy, which may pose a risk of fire or the like.

Therefore, when a canopy is supported by pillars, a fence is installed around the lower end of the pillar, and in some cases, for aesthetic reasons, a flower bed is created between the fence and the pillar to prevent vehicles from colliding with the pillar. It is customary to

However, this measure creates nothing but a zone unrelated to the refueling service, that is, a dead space within the refueling service zone.

SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to provide a refueling system that effectively utilizes the dead space created by the canopy strut membrane device.

According to the present invention, the above object is achieved by a refueling facility in which an island is provided around the lower end of the canopy support, and a refueling machine is disposed on the island and along the support.

In this case, from the viewpoint of protecting the pillar, the refueling machine is divided into two boxes placed on both sides along the pillar, and one box houses equipment such as a flow meter and a control valve. It has a lower compartment, an upper compartment that stores a flexible hose, and a middle compartment that stores a refueling nozzle connected to the free end of the hose, and the other housing stores equipment such as a flow meter and control valve. It is advantageous to have a lower compartment for storing the indicator and an upper compartment for housing the indicator. It is preferable that a middle section is provided between the upper section and the lower section of the latter case, and is used as a refueling mode input operation section that enables so-called preset refueling by specifying the refueling amount or refueling amount, or free refueling.

Furthermore, a separate '□ box housing a lighting device can be placed above the support column.

The invention will now be explained in more detail with reference to embodiments shown in the accompanying drawings, in which: FIG.

In FIG. 1, A is a side wall of a gas station, B is a canopy with one edge supported on side wall A, and C is a floor serving as a gas service zone. Canopy on floor C

Similarly to the lower section □, there is a lower section 141b that stores equipment such as a flow meter and fixed piping °, and an upper section 142b that is a display meter storage section, and a so-called preset lubrication or free lubrication by specifying the amount of lubrication or the amount of lubrication. The central section 143b provides a refueling mode input operation section that enables the refueling mode input operation. - Furthermore, the upper and middle sections 142 as 1 of the casing 14A
43a and the upper and middle sections 142 of the casing 14B
bX1413b is provided on the back side as well as the front side, but the two are symmetrical, and the case 14
The lower sections of A and 14B have the same front and back sections (see comparison in Figure 2).

Therefore, with respect to one of these front and back installations, the illustrated embodiment is configured to supply three types of fuel, for example gasoline of different octane ratings, so that the flexible hose 16 is A set of three cylinders are stored in the upper section 142a of the case 14A, but it is impossible to refuel two or three of them at the same time.

Correspondingly, the display section 20 in the upper section 142b of the housing 14B has three oil type display sections 20a, 20b-, 20'c, each having a built-in lamp (not shown), and information related to these oil types. The refueling nozzle 18 is located in the middle section 14.
In-use display section 2012L, 201b of the refueling machine, which has a built-in lamp (not shown) that blinks when the nozzle is removed from the nozzle housing section 3a and turns off when the nozzle is attached.
201C is provided. Furthermore, the upper section is provided with display meters 202, 203, and 204 that display the iJi value per i based on the oil type, the amount of oil supplied, and the amount of oil supplied.

In the middle section 143b of the case 14B, there are a plurality of preset buttons 2 for presetting the specified refueling amount or the specified refueling amount.
2a, and a free oil supply amount 22b for canceling the brisset and creating a free oil supply state. The preset can be confirmed using a lamp (not shown) built into the preset button.

Incidentally, the refueling equipment 10 according to the present invention may be provided with lighting equipment. In the illustrated embodiment, this lighting fixture is shown as a housing 24 containing a lighting fixture 241 (FIG. 2), such as a fluorescent light.

This casing 24 is a rectangular parallelepiped, is fixed to the stanchion in the middle of the stanchion, and has an upper section 142a of the casing 14A.
Although the casing 24 is shown as being placed on the canopy B, the shape of the casing 24 is arbitrary, and it should be noted that the casing 24 can be attached directly to the lower surface of the canopy B rather than to the support. stomach. In order to reduce the weight, the case is made of a frame made of a lightweight metal such as an aluminum alloy and a plastic plate such as an acrylic resin plate. In this case, the plastic plate is translucent to reduce glare. is preferred.

The front and back parts of the machine are cut symmetrically, and only one of the front and back parts will be explained. Lower section 14]
A flow meter 15a and a control valve 15b are respectively disposed in the lower section 141a (space relationship 'fJ). Four flowmeters and control valves are arranged in the lower section 141b of the lower section 141b, respectively, and correspond to six flexible hoses 16 (front and back). One end of the fixed pipe 17 passing through the flowmeter 15a and the control valve 15b extends to near the bottom of an underground fuel tank (not shown) depending on the oil type, and a submerged pump ( (not shown) is installed (this submerged pump is provided because the space in the lower compartments 14+a and 14Ib is small, and if there is sufficient space, a normal pump can be used instead. The other end of the fixed pipe 17 terminates at the bottom of the two-part compartment 142a, to which the flexible hose 16 is attached. The fixed pipe arranged in the lower section 141b of the casing 14B is also conducted into the lower section 141a of the casing 14A through an opening (not shown) formed in the strut, and its second part is connected to the upper section. Note that it terminates at the bottom of compartment 142a.

A coil spring 161 made of steel wire and wound at a relatively large pitch is installed from the starting end of the flexible hose To this extent, a coil spring 162 made of steel wire with a relatively small pitch or zero pitch (winding force) is further installed, and by being supported by these coil springs, the flexible hose 16 as a whole is It is housed in the upper section 142a in an inverted U-shape. In this case, the end of the fixed pipe 17 to which the flexible hose 16 is to be attached is the upper section ii! ii+42a If it is slightly inclined toward the split wall 142a' side, the second part of the flexible hose 16, which has an inverted U-shape, will be attached to the split wall 142a as shown in FIG.
' to achieve reliable storage of the flexible hose 16.

This arrangement of the flexible hose 16 makes it easy to store it, and if the nozzle side end of the flexible hose is grasped and pulled, the upper compartment will open against the repulsive force of the coil spring 61.162. 142a to provide the required refueling service band.

A refueling nozzle attached to the free end of the flexible hose 16 is attached to a nozzle hook 143a' formed in the middle section 143a. Note that a nozzle hook switch 26 is provided in the middle section 143a, and this switch is connected to the refueling nozzle 1.
When the nozzle hook 8 is removed from the nozzle hook 143 a', /n', the nozzle is turned on, and when it is attached, the nozzle hook is turned off.

Next, the operation of the refueling equipment 10 according to the present invention will be explained with reference to FIG. 3 as well.

Before the start of operation, unit price, refueling amount, and refueling amount display meters 202, 203, and 204 arranged in the upper section of the casing 1/l B display numerical numbers related to the previous refueling service.

For operation, first press the free refueling amount 22111 provided in the box 14B (~section +43b) for free refueling such as full tank refueling, or press the refueling amount or Preset fuel amount button 222L
Press to set. You can confirm whether free lubrication or preset lubrication has been set because the lamps (not shown) built into these buttons will light up, and the free lubrication signal or preset lubrication signal will be sent to signal path L1. Or, via L2, the oil supply nozzle 182 and nozzle hook 14 for the type of oil specified by the customer in Figure 9, for example, oil.
Get out of 3a' (Figure 2). In this case, the switch 26 for the nozzle hook is turned on and a nozzle release signal is generated, and this signal is sent to the control device 2 through the signal path L3.
Get sent to 8. Control device 28 that received the nozzle removal signal
sends a signal to the display section 20 through the signal path L4 to make the indicator 202 displaying data regarding the previous refueling and the lamp (not shown) built in the oil machine in use display section 201a blink. The control device 28 is connected via a signal path to an associated pump 7 (FIG. 3 - in this embodiment, this is a submerged pump attached to the lower end of the fixed pipe 17 as described in connection with FIG. 2). A signal is sent to the control valve 15b to start it, and a signal is sent to the control valve 15b through the signal path L6 to open it.

As the preparations for introductions 1 and 4 are completed as described above, the worker inserts the tip of the refueling nozzle 18 into the refueling port of the customer's vehicle and pulls the trigger to start refueling. In this case, the flow rate pulse transmitter 151a provided in the flow meter 15a sends a pulse signal to the control device 28 via the signal path L7, and based on this, the control device f
dj 28 sends a signal to the refueling amount display meter 203 and refueling amount display meter 204 of the display section 20 through the signal path L4. Therefore, the numerical values on these indicators change every moment as the refueling operation continues.

In the case of preset refueling, when the refueling amount or refueling amount reaches the specified value, the control valve +5b is closed by a signal sent from the control device 28 to the control valve +5b through the signal path L6, and refueling is stopped. It will be stopped automatically. On the other hand, in the case of free refueling, even if refueling is completed and the trigger of the refueling nozzle 18 is released, the control valve 15b will not be closed.

To close the control valve 15'b, when the refueling nozzle 18 is returned to the nozzle hook 143a', the nozzle hook switch 26 is turned off, and the control valve 15'b is closed via the signal path L3.
8, and based on the signal, the control device 28 sends a valve closing signal through the signal path L6.

Based on the signal, the control device 28 turns off the lamp of the in-use display section 201a in the display section 20 through the signal path L4, and pumps up the nozzle through the signal path L5. Deactivate the power amplifier 7.

In addition, in the description under "-", the refueling nozzle 18 is only retracted after the free refueling amount 22b or the preset refueling amount 22a is pressed, but there is no problem even if the refueling nozzle is retracted and retracted first.
