Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil supply device, and more particularly to an oil supply device suitable for simultaneously supplying a plurality of vehicles having different oil types and a vehicle.

2. Description of the Related Art A conventional double-type refueling device has, for example, a refueling hose for refueling regular gasoline and a refueling nozzle provided on one side of the body casing of the refueling device, and light oil or high-octane oil on the other side of the body casing. A refueling hose and refueling nozzle for refueling either one of the gasoline are provided, and a refueling amount indicator that displays the refueling amount of regular gasoline and a refueling amount of light oil (or high-octane gasoline) on the front and rear faces of the main body housing. And a refueling amount display for displaying.

Therefore, in the conventional refueling device having the above-described configuration, in the refueling space on either the front or rear side of the main body casing of the refueling device, whichever of the vehicle refueling regular gasoline or the vehicle refueling light oil (or high-octane gasoline) is In order to be able to refuel even when the vehicle is stopped, a total of two refueling systems consisting of refueling hoses of different oil types and refueling nozzles were provided on one side surface of the main body casing.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the refueling device having the above-described configuration, refueling is simultaneously performed on a plurality of vehicles of the same oil type, for example, regular gasoline vehicles, in refueling spaces on both front and rear sides of the body housing of the refueling device. In the case where it is necessary to do so, even if the refueling space of a vehicle of a different oil type from the relevant oil type, for example, the remaining refueling space on either the front or rear surface side due to a light oil vehicle is open, refueling of regular gasoline Since there is only one system, it is necessary to exhaust the refueling of regular gasoline vehicles one by one, and the waiting time for refueling the subsequent regular gasoline vehicles will be long, and the refueling staff will not be able to work efficiently. There was a problem. This problem frequently occurs due to the current situation that the number of vehicles that refuel regular gasoline is generally much larger than the number of vehicles that refuel light oil (or high-octane gasoline).

Therefore, in order to solve such a problem, if a plurality of double-type refueling devices of this kind are installed side by side on the site of the refueling station as a refueling facility, there will be multiple vehicles that refuel with the same oil type. Can be refueled without waiting for the customer of the following vehicle, but this requires a large installation space, and therefore cannot be applied to a gas station with a small site area. In addition, even if multiple refueling stations of this type are installed at a refueling station with plenty of site area, there is a front and rear refueling space for each refueling system, so the refueling systems are separated from each other. Inevitably, the refueling staff will have to go back and forth between the refueling devices as the vehicles of the same oil type are refueled at the same time, and will not only require a great deal of labor, but also the number of customers per customer. However, there is a problem that it is limited.

Therefore, the applicant of the present invention has proposed a refueling device in which two refueling hoses are connected to both side surfaces of the refueling device main body as shown in Japanese Utility Model Laid-Open No. 60-134797, so that four vehicles can be refueled at the same time. Proposed.

In the oil supply device of this publication, two nozzle hooks to which oil supply nozzles connected to two oil supply hoses for oil type A are hooked are provided side by side on one side of the oil supply device main body, and the other one is provided. On the side surface, two nozzle hooks to which the oil supply nozzles connected to the two oil supply hoses for oil type B are hooked are provided side by side.

Therefore, in the above oil supply device, it is possible to simultaneously supply oil to the two A-oil type vehicles and the two B-oil type vehicles. However, when actually refueling at the fueling station, the vehicle is stopped at a position where the customer can view the refueling amount indicator from the vehicle, so only one vehicle is stopped on the front side and the rear side of the refueling device main body.

Here, for example, when the type A oil is regular gasoline and the type B oil is light oil, since the number of regular gasoline vehicles is generally larger than the number of light oil vehicles, regular gasoline is provided on the front side and the rear side of the refueling device main body. A case in which one vehicle is stopped and refueling at the same time, and a case in which a regular gasoline vehicle is stopped on the front (rear) side of the refueling device body and a light oil vehicle is stopped on the rear (front) side to refuel simultaneously However, there are very few cases where one light oil vehicle is stopped and fueled on the front side and the rear side of the refueling device main body.

As described above, even if there are two regular gasoline refueling systems, since there are many regular gasoline vehicles, there are often cases where the front side and the rear side of the refueling device main body are simultaneously refueled. Even if there are two light oil refueling systems, the number of light oil vehicles is small, so there are almost no cases where the front and rear surfaces of the refueling device main body are simultaneously refueled, and the frequency of use is low.

Therefore, the gas oil refueling system rarely refuels from two systems at the same time, and one of the two gas oil refueling systems is always unused and idle, and it is wasteful to provide two systems.

Further, since the nozzle hooks of the same oil type are arranged side by side on the side of the refueling device main body, when refueling simultaneously on the front side and the rear side of the refueling device main body, the front side refueling nozzle that has been refueled first The fuel may be accidentally hooked back onto the nozzle hook of the oil filler nozzle on the rear side.

In that case, since the nozzle switch of the refueling system during refueling is turned off, although the refueling system on the rear side is refueling, the refueling amount indicator does not count up and is in a stopped state, or the POS terminal The voucher is issued from the machine, and the refueling amount indicator of the front side refueling system that has been refueled is still in operation and the voucher is not issued from the POS terminal.

Therefore, an object of the present invention is to provide an oil supply device that eliminates the above-mentioned drawbacks.

Means for Solving the Problems The oil supply device according to the present invention includes a first pump, which is communicated with one tank on the inflow side in which an oil species having a relatively high oil supply frequency is stored, and a discharge of the first pump. First and second flowmeters connected to each other via a branch pipe, and a first oil supply nozzle provided at the tip end of the first flowmeter, the first end of which is connected to the outflow side of the first flowmeter. Oil supply hose, a second oil supply hose having a second oil supply nozzle at the tip and a base end communicating with the outflow side of the second flow meter, and the oil supply side relatively infrequently supplies oil. A second pump that communicates with another tank that stores seeds, a third flow meter that is connected to the discharge side of the second pump, and a third refueling nozzle at the tip. A third oil supply hose provided with its base end communicating with the outflow side of the flowmeter of And the first, second, and third flowmeters are housed in one housing, and a nozzle hook for hanging the first fueling nozzle on the front surface of the housing and a fueling tank measured by the first flowmeter. A fuel supply amount display for displaying the amount of fuel and a fuel supply amount display for displaying the amount of fuel supply measured by the third flow meter are provided, and a nozzle for hooking the second fuel supply nozzle on the rear surface of the housing. A casing, an oil supply amount display for displaying the amount of oil supply measured by the second flow meter, and an oil supply amount display for displaying the amount of oil supply measured by the third flow meter, Is provided on a side surface of the housing, the first oil supply hose is extended from a front surface of the housing or a side surface near the front surface, and the second oil supply hose is connected to the housing. While extending from the back or side of the body towards the back, The serial third oil supply hoses extend to be movable in the front-rear side from the side surface of the housing, characterized by comprising.

Action For oil types that are frequently refueled, it is possible to arrange a refueling system on the front and rear surfaces of the housing and to refuel vehicles that are stopped on the front and rear sides of the housing at the same time. As for the seed, it is possible to arrange a refueling system that is movable in the front-rear direction on the side surface of the housing to refuel a vehicle stopped on one of the front surface side and the rear surface side of the housing. Therefore, a tank for the oil type having a high refueling frequency is connected to the first pump, and a tank for the oil type having a low refueling frequency is connected to the second pump.
By connecting it to the pump of the above, the oil supply system consisting of the oil supply hose and the oil supply nozzle is arranged on the front surface and the rear surface of the housing for multiple oil types that are frequently refueled. Since one refueling system can be moved to the side of the housing, it is possible to improve the service to the demand of oil types that are frequently refueled, and to effectively utilize the premises of the refueling station. Work efficiency can be improved. Also, since each nozzle hook is separated into the front and rear surfaces of the housing for the same oil type, and is separated into the front surface, rear surface and side surface of the housing for different oil types, it is possible to accidentally use a different nozzle hook when refueling is completed. Do not hang back the fueling nozzle.

Embodiment FIG. 1 shows an embodiment of an oil supply device according to the present invention.

In the figure, three refueling systems 2 to 4 are provided in a refueling device main body (housing) 1. Of the refueling systems 2 to 4, for example, two refueling systems 2 and 3 are connected to an underground tank 5 that stores regular gasoline that is frequently refueled.
The remaining refueling system 4 is connected to an underground tank 6 that stores light oil that is relatively infrequently refueled.

That is, the refueling device according to the present invention is the front of the refueling device main body 1,
A vehicle stopped at the rear surface can be refueled regardless of the type of oil, and a vehicle of an oil type (light oil in this embodiment) that is less frequently refueled can be refueled simultaneously on the front and rear surfaces of the refueling device main body 1. The above-mentioned configuration is made paying attention to the fact that there is almost no.

Therefore, in the main body 1 of the refueling device installed on the island 7, the refueling systems 2 and 3 for regular gasoline and the refueling system 4 for light oil having different types of oil can be accommodated to accommodate the customer's acceptance.
And are provided.

A first pump 9 is provided in a pipe 8 communicating with the regular gasoline tank 5. A branch pipe 10 (10a, 10b) is connected to the pump 9. First and second flowmeters 11 and 12 of the oil supply systems 2 and 3 are arranged in the respective branch pipes 10a and 10b.

Reference numeral 13 is a fixed pipe for regular gasoline, one end of which is connected to the flow meter 11 of the branch pipe 10a and the other end of which extends to the front side of the right side surface of the refueling device main body 1 for the regular gasoline.
Is connected to the fuel supply hose 14 of FIG. Incidentally, 46 is a solenoid valve, which is arranged in the fixed pipe 13.

The refueling hose 14 has a first refueling nozzle 15 at the tip,
The base end portion is fixed to the front surface side of the right side surface of the refueling device main body 1, and supplies the oil liquid in the tank 5 pumped up by the pump 9 to the refueling port of the vehicle through the refueling nozzle 15.
Further, a first nozzle hook 37 for hooking the oil supply nozzle 15 is arranged on the front surface of the fuel supply apparatus main body 1 (see FIGS. 3 and 4).

Therefore, the pipe 8, the pump 9, the branch pipe 10a, the flow meter 1
1, the fixed pipe 13, the solenoid valve 46, the oil supply hose 14, and the oil supply nozzle 15 constitute an oil supply system 2. Further, the refueling system 3 is also similar to the refueling system 2 described above, including the pipe 8, the pump 9, the branch pipe 10b, the flow meter 12, the fixed pipe 16, the solenoid valve 47, the second refueling hose 17, and the second refueling nozzle 18.
It is composed by.

The other end of the regular gasoline fixed pipe 16 whose one end is connected to the flow meter 12 extends to the rear surface side of the right side surface of the refueling device main body 1 and is connected to the regular gasoline refueling hose 17. That is, the base end portion of the fuel supply hose 17 having the fuel supply nozzle 18 at the tip is fixed to the rear surface side of the right side surface of the fuel supply device main body 1. Further, a second nozzle hook 38 for hooking the oil supply nozzle 15 is provided on the front surface of the fuel supply apparatus main body 1 (see FIGS. 3 and 4).

Therefore, since both refueling systems 2 and 3 refuel regular gasoline having a high refueling frequency, the pipe 8, pump 9, and branch pipe 10 are shared by both refueling systems 2 and 3.

When neither of the oil supply systems 2 and 3 is in use, the solenoid valves 46 and 47 are closed and the fixed pipes 13 and 1 are
Blocking 6 This is because, for example, when performing refueling work on one of the refueling systems 2 and 3, the refueling nozzle is operated while the nozzle switch, which will be described later, does not intentionally operate on the other refueling system, and illicit refueling occurs. This is to prevent it from being done.

Therefore, for example, as shown in FIG. 2, even if two regular gasoline vehicles A and B that are refueled with regular gasoline arrive at the gas station continuously, the two vehicles A and B are refueled by the refueling systems 2 and 3. B can be refueled at the same time. Therefore, even when two or more vehicles are refueled with regular gasoline, they can be refueled without waiting too long for other customers, and a high-quality service can be provided to the customers.

Further, when refueling is started from the refueling nozzle 15 of the refueling system 2, the flow meter 11 measures the amount of refueling, and along with this, the pulse generator 19 sends a flow rate pulse to the display 20.

Reference numeral 21 denotes a nozzle switch provided on the nozzle hook of the refueling nozzle 15 corresponding to the refueling system 2. When the refueling nozzle 15 is picked up, it is activated to reset the indicator 20 provided on the front surface of the refueling device main body 1 to reset the solenoid valve. 46 is opened and the pump 9 is started.

Further, regarding the refueling system 3, 22 is a pulse transmitter of the flow meter 12, 23 is an indicator provided on the rear surface of the refueling device body 1, and 24 is a nozzle switch provided on the nozzle hook of the refueling nozzle 18. . Therefore, when the refueling nozzle 18 of the refueling system 3 different from the above is picked up from the nozzle hook, the indicator 23 is reset, the solenoid valve 47 is opened, and the pump 9 is started.

It should be noted that the pump 9 has a capacity capable of sufficiently pumping up the oil liquid in the tank 5 even if the oil is supplied from the oil supply systems 2 and 3 at the same time.

A pump 26, which is different from the pump 9, is provided in the pipe 25 communicating with the light oil tank 6. Pump 26
The oil liquid in the underground tank 6 pumped up by the
Oil is supplied through the pipe 27, the flow meter 28, the movable pipe 29, the third oil supply hose 30, and the third oil supply nozzle 31 that configure the above.

Further, when refueling is started, the flow rate is measured by the flow meter 28 and the pulse signal from the pulse transmitter 32 is supplied, and the indicator 33 provided on each of the front and rear surfaces of the main body 1 as shown in FIG. , 33 displays the amount of light oil supplied.

Reference numeral 34 denotes a nozzle switch provided on the nozzle hook of the fuel nozzle 31, and when the fuel nozzle 31 is taken up from the nozzle hook, the indicator 33 is reset and the pump 26 is started.

As described above, in the refueling device main body 1, the flowmeters 11, 12, 28 and the indicators 20, 23, 33, and
33 is provided, and each vehicle can be individually refueled from each refueling nozzle 15, 18, 31. Therefore, 1
It is possible to refuel two vehicles with gasoline by means of one refueling device and at the same time refuel one vehicle with light oil.

The movable pipe 29 of the refueling system 4 for refueling light oil is provided so as to be displaceable in the front-rear direction (X ₁ , X ₂ direction) of the refueling device body 1 by a moving mechanism described later. This is because the number of light oil vehicles is considerably smaller than the number of running regular gasoline vehicles, and as described above, it is almost impossible for a light oil vehicle having a low refueling frequency to refuel at the front and rear surfaces of the refueling device body 1 at the same time. Because there is no.

However, as shown in FIG. 2, even when the regular gasoline vehicles A and B are being refueled, when the two vehicles C or D that refuel with light oil arrive at the refueling station, the vehicles C or D are moved to one side of the island 7. It is possible to stop the vehicle and to refuel at the same time while refueling the vehicles A and B.

Further, as shown in FIG. 2, even when the four vehicles A to D are continuously refueled, the worker can quickly deal with the problem without going back and forth between the refueling devices, and at a limited gas station. Space can be used effectively.

Here, the oil supply device will be described in more detail with reference to FIGS. 3 to 5. Incidentally, in FIGS. 3 to 5, the same components as those in FIG. 1 are designated by the same reference numerals and the description thereof will be omitted.

3 and 4, on the right side surface 1a of the main body 1 of the lubrication apparatus, the lubrication hoses 14 and 17 of the lubrication systems 2 and 3 and the lubrication nozzle 1 are provided.
5, 18 are provided. The refueling hoses 14 and 17 are joints 35 and 3 fixed to the upper portion 1b of the refueling device main body 1, respectively.
6 is suspended from the front and rear surfaces of the refueling device main body 1.

Further, the refueling nozzles 15 and 18 for regular gasoline are the nozzle hooks 37 provided on the front and rear surfaces of the refueling device main body 1,
It is hooked at 38.

The nozzle switch 2 is attached to the nozzle hooks 37 and 38.
Nos. 1 and 24 are provided, and the nozzle switches 21 and 24 are operated in response to the engagement / disengagement of the fueling nozzles 15 and 18.
Therefore, the refueling nozzle 15 or 18 is attached to the nozzle 3
Nozzle switch 21 or 2 taken from 7, 38
4 operates, the motor 39 is energized to drive the pump 9, the solenoid valve 46 or 47 of the refueling system with the refueling nozzle removed is opened, and the indicator 20 or 23 is reset to zero to refuel. It becomes possible.

As shown in FIGS. 3 and 5, the left side surface 1c of the main body 1 of the oil supply apparatus is provided with a nozzle hook 40 for locking the oil supply nozzle 31 for light oil. In this nozzle hook 40,
A nozzle switch 34 is provided which is operated by hooking and unplugging the fueling nozzle 31. Therefore, by picking up the oil supply nozzle 31 from the nozzle hook 40, the motor 41 is activated and the pump 26 is driven, and the oil can be supplied.

The refueling hose 30 of the refueling system 4 is connected to the joint 42 of the upper portion 1b of the refueling device body 1. This joint 42 is a guide rail 43 extending in the X ₁ and X ₂ directions of the upper portion 1b.
It is slidably mounted on the.

Further, the joint 42 is connected to a pipe 46 from the flowmeter 28 via connecting pipes 44 and 45 which rotate following the sliding of the joint 42. The connecting pipes 44 and 45 are the movable pipe 2
Equivalent to 9.

Thus, when refueling the vehicle C has stopped at the front side of the fuel supply device main body 1, the joint 42 by pulling the refueling hose 30 in the X ₁ direction slides in the X ₁ direction along the guide rail 43. Therefore, the refueling hose 30 is hung from a position close to the vehicle C, so that refueling of the vehicle C is easy.

Next, when refueling the vehicle D stopped on the rear surface side of the refueling device main body 1 after the refueling of the vehicle C is completed, the refueling hose 30 is connected to X.
Just pull in _two directions. As a result, the joint 42 slides in the X ₂ direction and oil is easily supplied to the vehicle D. When refueling is performed from the refueling nozzle 31, the amount of refueling is displayed on the front and rear surfaces of the refueling device main body 1 by the indicators 33, 33.
Displayed by. Therefore, no matter which side of the front and rear surfaces of the refueling device main body 1 the vehicle is stopped, the operator can confirm the refueling amount by the indicators 33 arranged on both sides.

As described above, since the nozzle hook 37 is arranged on the front surface of the oil supply apparatus main body 1 and the nozzle hook 38 is arranged on the rear surface of the oil supply apparatus main body 1, for example, the oil supply nozzles 15, 15 of the same oil type,
When 18 is simultaneously refueling, when the refueling nozzle 15 that has been refueled first is returned to the nozzle hook 37, it does not return to the nozzle hook 38 on the opposite side by mistake, and two nozzle hooks are arranged side by side as in the conventional case. There is no risk of mistakes like the provided refueling device.

That is, each of the nozzle hooks 37, 38, 40 is connected to the fuel supply device main body
Since it is divided into the front, back and side of the, it is possible to prevent the refueling nozzle from being accidentally put back on another nozzle when refueling is completed, and it is not necessary to re-display the amount of refueling or to issue a slip again. No annoyance to customers.

Effects of the Invention As described above, the oil supply device according to the present invention is applied to a vehicle in which an oil supply system is arranged on the front surface and the rear surface of the housing for oil types that are frequently supplied, and the vehicle is stopped on the front surface side and the rear surface side of the housing. For the types of oil that can be refueled at the same time and that are refueled infrequently, a refueling system that can move in the front-rear direction should be placed on the side of the housing to refuel a stopped vehicle on either the front or rear side of the housing. You can Therefore, by connecting the tank of the oil type having a high refueling frequency to the first pump and the tank of the oil type having a low refueling frequency to the second pump, the oil type having a high refueling frequency is connected. For each type, multiple refueling systems consisting of refueling hoses and refueling nozzles should be installed on the front and rear surfaces of the housing, and for oil types that are infrequently refueled, one refueling system should be able to move to the side of the housing. As a result, it is possible to improve services to meet the demand for oil types that are frequently refueled, make effective use of the site of the gas station, and improve the work efficiency of the gas station staff. Also, since each nozzle hook is divided into the front and rear surfaces of the casing for the same oil type, and is separated into the front and rear surfaces and side surfaces of the casing for different oil types, it is mistaken to fill another nozzle hook when lubrication is completed. It is possible to prevent the nozzle from being hooked back, and it is not necessary to re-display the amount of refueling or to issue the slip again, so that it does not disturb other refueling customers. Further, for an oil type that is relatively infrequently refueled, by connecting the tank of the oil type to the second pump, one refueling system can be moved to the front and rear sides of the refueling device housing. The number of refueling systems is the minimum necessary, and there is no need to let the refueling system play without being used. Even if two vehicles arrive at the refueling station, both of them stop at the front and rear sides of the refueling device. Refueling can be done sequentially while keeping the same, the labor of the refueling worker can be reduced, and the number of refueling systems handled by one worker can be increased, which enables efficient refueling work. Therefore, the space of the gas station can be effectively used. Further, in the case of a gas filling station to which oil supply pipes of two different oil types are already attached for the conventional oil supply device described in the conventional example, the oil supply pipes are used to provide only two conventional oil supply systems. It has features such that an oil supply device having three systems can be easily installed in place of the device.
