DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refueling device installed in a refueling station for refueling automobiles or the like with fuel such as gasoline.

[0002]

2. Description of the Related Art There is a hose suspension type lubricating apparatus which suspends a lubricating hose from a canopy which covers an upper area of a gas station. This hangs a hose treatment device from the canopy,
An oil supply hose having an oil supply nozzle at the tip thereof is suspended from the hose processing device, a pump room is provided adjacent to a building such as an office installed on the site, and an oil supply pipe communicating with an underground oil storage tank in the pump room. And an oil supply pump connected to an oil supply motor and a flow meter connected to a flow rate pulse transmitter are provided in the middle of the oil supply pipe.

[0003] Then, the leading end of the oil supply pipe is led out into a case of a hose processing apparatus, and one end of an oil supply hose wound around a hose reel provided in the case of the hose processing apparatus is connected to the oil supply pipe. In addition, an indicator for displaying refueling data such as the amount of refueling is provided at an easily visible location such as a wall surface of a building such as an office.

By the way, the length of the refueling hose drawn out of the hose treatment device, that is, the height position of the refueling nozzle at the tip, should not be tampered with when the store is closed or when a large truck enters or leaves, so as not to hinder the traveling of the large truck. The refueling hose is hardly pulled out, and the refueling nozzle is in the raised position located immediately below the case of the hose processing device.

On the other hand, when the store is open and ready for refueling, the worker reaches up below the raised position so as not to hinder the entry and exit of workers and cars. It is in the standby position at the height position that sometimes reaches. Further, when refueling the vehicle, the vehicle is at the lowest refueling position, which is the height position where the refueling nozzle can be inserted into the refueling port of the vehicle.

[0006] Since the refueling nozzle is located at the raised position only in a limited time such as when the store is closed, the refueling hose is raised and lowered by a switch provided in an office or the like. On the other hand, the raising and lowering between the standby position and the refueling position is performed at each refueling during the business hours, and thus, conventionally, for example, a raising and lowering switch is provided in a refueling nozzle or a refueling hose in the vicinity thereof. Was.

The up / down switch comprises an up switch and a down switch. Since the down switch is operated to lower the oil supply hose when in the standby position, the lower switch in the upper standby position is manually operated. It is a string switch with a string suspended so that it can be easily reached, and pulling down the string turns on the descent switch. At the time of refueling, pull the string of this down switch, pull out the refueling hose, lower the refueling nozzle to the refueling position, turn on the refueling pump at the same time, and when the refueling is completed, press the push button type up switch set up on the down switch. Push and wind up the refueling hose to raise the refueling nozzle to the standby position.

[0008]

As described above, conventionally, a lubricating hose wound around a hose reel in a case of a hose processing device so as to be able to be pulled out freely is provided between the standby position and the lubricating device each time when refueling. Since it is raised and lowered, a switch for raising and lowering is required. In this case, since the lifting switch is provided at or near the fueling nozzle for easy operation, it is necessary to have an intrinsically safe explosion-proof structure, which is expensive.

A signal line for sending an ON signal from the elevation switch to a hose reel motor for driving the hose reel is connected to the switch. This signal line is wired along the oil supply hose. Therefore, when the refueling hose is directed in the refueling direction, the signal line must be bent together with the refueling hose, and the operability is poor. In some cases, the signal line may be disconnected.

Further, since the oil supply hose is moved up and down each time the oil is refueled, a lot of energy is required for elevating and lowering the oil supply hose, and the efficiency of the oil supply operation is not good.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned disadvantages of the prior art and to make use of the advantage of a suspension type lubricating apparatus, which eliminates the need to install a gasoline lubricating machine housing on the ground. This eliminates the need to raise and lower the refueling hose between the position and the refueling position, eliminates the need to provide an elevating switch near the refueling nozzle, and furthermore, even if the refueling port of a vehicle stopped along the island is on the opposite side of the island. The refueling hose can be easily moved, and after refueling is completed, the refueling hose can be automatically returned to the fixed position on the island side, preventing the refueling hose from being in the way until the next refueling. An object of the present invention is to provide an oil supply device that can improve workability.

[0012]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention hangs a refueling hose having a refueling nozzle at the tip from a canopy located above a refueling area formed on the left and right sides of a small and elongated island. A hose reel around which a refueling hose is wound is disposed slidably in a direction perpendicular to the island in a case of the hose processing apparatus, and the island is provided below the hose processing apparatus. , A case provided with a nozzle hook provided with a nozzle switch is provided upright, and an indicator is provided. When the refueling nozzle is hooked on the nozzle hook and the nozzle switch is off, the hose reel is fixed to the case side. The gist is that a fixed position detection switch for moving the hose processing device is provided in the hose processing device.

[0013]

According to the present invention, the refueling hose suspended from the canopy does not move up and down during business hours, and the refueling nozzle is locked to the nozzle hook provided on the island. The operability is good simply by removing and returning the nozzle from the nozzle hook. Also, since the indicator is provided on the same island, it is located in the flow line of the refueling operation, and is easy to see. Furthermore, when the fuel filler of a car stopped along the island is on the opposite side of the island, the hose reel slides inside the case, so the fuel filler hose can be easily moved in the direction of the fuel filler. If you return the refueling nozzle at the tip of the
Since the nozzle switch is turned off and the home position detection switch is turned on thereby, the hose reel moves in the case toward the island and returns to the home position. As a result, the refueling hose is accommodated in the island, so that the refueling hose will not be caught by the vehicle or hinder the traveling until the next refueling.

The display 22, the keyboard 24, the card reader 25, and the printer 26 are commonly used for three oil types.

FIG. 4 is a block diagram of the refueling control, and includes a fixed position detecting switch 17a provided for each of the hose processing devices 4a to 4c.
Drive signals for the laterally moving motors 16a to 16c from the motors 16a to 16c are introduced into drive means 28a, 28b and 28c for the motors 16a to 16c via gates 27a, 27b and 27c.

A driving means for the refueling motors 10a to 10c via the respective gates 29a, 29b, 29c outputs an ON signal when the refueling nozzles 5a to 5c from the nozzle switches 20a to 20c are removed from the nozzle hooks 18a to 18c. Introduced to 30a, 30b, 30c, the ON signal of the nozzle switch 20a is sent to the gates 29b, 29c of the other oil supply system, the ON signal of the nozzle switch 20b is sent to the gates 29a, 29c of the other oil supply system, and the nozzle switch
The ON signal of 20c is introduced as a gate closing signal to the gates 29a and 29b of the other refueling systems.

Also, a flow pulse transmitter 11a of each oil supply system
Counting means through the switching means 31
The ON signal from each of the nozzle switches 20a to 20c was introduced into the switching means 31 as a switching connection signal, and at the same time, was introduced into the counting means 32 as a reset signal.

Then, the counting signal from the counting means 32 is introduced into the driving means 33 of the display 22 and also as the refueling data signal to the driving means 34 of the printer 26. The counting signals from the nozzle switches 20a to 20b are also transmitted. The OFF signal is introduced to the driving means 34 as a print command signal.

FIG. 5 is a block diagram of the elevation control of the oil supply hose 6a. An ON signal from the elevation switch 21a and an ON signal of the upper contact CSW1 of the cam switch 14 are introduced into the AND circuit 36, The output signal is introduced as a set signal of the flip-flop circuit 37, the output signal from the flip-flop circuit 37 is introduced as a normal rotation drive signal to the drive means 35 of the hose reel motor 13, and the ON signal of the lower contact CSW2 of the cam switch 14 is turned on. To the flip-flop circuit 37 as a reset signal.

The ON signal of the lift switch 21a and the ON signal of the lower contact CSW2 of the cam switch 14 are introduced into an AND circuit 38, and the output signal from the AND circuit 38 is introduced as a set signal of a flip-flop circuit 39. Then, the output signal from the flip-flop circuit 39 was introduced to the drive means 35 of the hose reel motor 13 as a reverse drive signal, and the ON signal of the upper contact CW1 of the cam switch 14 was introduced to the flip-flop circuit 39 as a reset signal. The refueling hoses 6b, 6c are controlled to move up and down in a similar manner.

Next, the operation will be described with reference to the flowchart of FIG. 6 showing the raising / lowering operation of the oil supply hose 6a. While the store is closed, the refueling hose 6a is wound around the hose reel 12, and the refueling nozzle 5a is located immediately above the hose processing device 4a. At the time of opening the store, the card reader 25 reads the responsible card possessed by the person in charge of the gas station with the card reader 25 (step B in FIG. 6), and then pushes the elevating switch 21a (step B). Is ON (step c), the ON signal from the up / down switch 21a and the ON signal from the upper end contact CSW1 enter the AND circuit 36, and the signal from the AND circuit 36 sets the flip-flop circuit 37. The hose reel motor 13 rotates forward.

As a result, the oil supply hose 6a wound around the hose reel 12 is pulled out of the hose processing device 4 and descends. Then, when the refueling nozzle 5a is lowered to the lower end position during business, the lower contact point CSW2 of the cam switch 14 is turned on (step E), and this ON signal enters the flip-flop circuit 37 as a reset signal. Since the normal rotation drive signal output is eliminated, the hose reel motor 13 stops (step F), and the oil supply hose 6
a and the refueling nozzle 5a stop at the lowered position during operation.
Therefore, the refueling nozzle 5a is hung on the nozzle hanger 18a. Similarly, the refueling hoses 6b and 6c are lowered to prepare for refueling.

For example, to supply high-octane gasoline, a high-octane gasoline refueling nozzle 5a is removed from the nozzle hook 18a, and the nozzle switch 20a is turned on in conjunction therewith (step nu in FIG. 7). Refueling motor 10
a is turned on to be in a refuelable state. At the same time, this ON signal is used as a reset signal by the counting means 32 connected to the display 22.
And the previous refueling amount is returned to zero. Further, this ON signal enters the gates 29b and 29c of the other refueling systems and closes them. As a result, even if the refueling nozzles 5b and 5c are removed, the ON signals from the nozzle switches 20b and 20c will not be transmitted to the gates 29b and 29c.
c and cannot be refueled at the same time (steple).

When the refueling nozzle 5a is inserted into the refueling port of the vehicle and the valve is opened, the high-octane gasoline pumped from the underground oil storage tank by the refueling pump is discharged from the tip of the refueling nozzle 5a, and thus refueling is performed. The flow rate during this time is measured by the flow meter, and enters the counting means 32 as a pulse signal from the flow rate pulse transmitter 11a, where it is counted and displayed on the display 22 as the amount of refueling (steps I and W).

When the refueling is completed and the refueling nozzle 5a is returned to the nozzle hook 18a, the nozzle switch 20a is turned off (step f), and this off signal is sent to the driving means 30a of the refueling motor 10a.
And the refueling motor 10a stops. At the same time, the OFF signal enters the driving means 34 of the printer 26, and a refueling slip on which refueling data such as the refueling amount input from the counting means 32 is printed is issued (step Y).

When the fuel filler of the vehicle stopped on the right side of the island 2 is on the right side, the vehicle is moved to the island 2
If the oil supply hose 6a is pulled to the right of the vehicle without moving the hose 15 to the left side, the case 15 accommodating the hose reel 12 moves laterally in the case of the hose processing device 4a. Thus, the refueling hose 6a is moved to the right side of the automobile to refuel. During this time, the case 15 is
By moving away from the position a, the home position detection switch 17a is turned off, but while the nozzle switch 20a is on, the motor 16a is stopped because the gate 27a is closed.

As described above, the filler port of the automobile is located on the island 2
If not, the refueling hose is moved to the refueling port on the opposite side to perform refueling, but when refueling is completed and the refueling nozzle 5a is returned to the nozzle hook 18a and turned off, the off signal enters the gate 27a. Therefore, the gate 27a is opened, the drive signal from the fixed position detection switch 17a enters the drive means 28a, and the lateral movement motor 16a is driven to move the case 15 to the island 2
To the fixed position on the side (step, レ).

When the case 15 moves to the home position, the case 15
Contacts the contact of the fixed position detection switch 17a and turns it on (step Saw). As a result, the output of the drive signal stops, the motor 16a stops (steps), the case 15 containing the hose reel 12 stops at the fixed position on the island 2 side, and prepares for the next refueling. When the refueling nozzle 5a is hung on the nozzle hook 18a in this manner, the case 15 automatically moves to the island 2 side, and the refueling hose 6a is housed in the island 2,
It doesn't get caught in the car or hinder running.

When the store is closed, the manager causes the card reader 25 to read the manager card (step a in FIG. 6), and the keyboard 24
Is operated to refuel the nozzles 5a to 5c with the nozzles 18a to 18c.
After closing the store where the nozzle switches 20a to 20c are not turned on even if the nozzle switch 20a is removed from the nozzle 18c, the fuel supply nozzle 5a is set to the nozzle hook 18a.
And press the up / down switch 21a (Step B).

In this state, since the refueling nozzle 5a is at the lower position, the lower contact CSW2 of the cam switch 14 is turned on, and this ON signal and the ON signal of the elevation switch 21a enter the AND circuit 38. The flip-flop circuit 39 is set by the signal, the hose reel motor 13 rotates in the reverse direction, the oil supply hose 6a is wound on the hose reel 12, and the oil supply nozzle 5a rises (step). When the refueling nozzle 5a moves to the upper end position when the store is closed, the upper end CSW1 of the cam switch 14 is turned on (step), and this signal enters the flip-flop circuit 39 as a reset signal, and the reverse drive from the flip-flop circuit 39 is performed. When the signal output stops, the hose reel motor 13 stops (steply), and the refueling hose 6a and the refueling nozzle 5a stop at the upper closed position. Similarly, the fueling hoses 6b and 6c are also raised to prevent the fueling nozzles 5a to 5c from being tampered with during closing.

[0037]

As described above, the lubricating apparatus of the present invention
While the refueling hose suspended from the upper canopy does not need to be moved up and down each time refueling while the store is open, the workability of refueling operation can be improved, and there is no need to provide a lifting switch for each refueling at or near the refueling nozzle. Since there is no need to wire the signal connected to the switch along the oil supply hose, it is easy to handle when refueling. Furthermore, when the fuel filler of a car stopped along the island is on the opposite side of the island, the hose reel slides inside the case, so the fuel filler hose can be easily moved in the direction of the fuel filler. When the oil supply nozzle at the end of the nozzle is returned to the nozzle hook, the nozzle switch is turned off and the home position detection switch is turned on, so that the hose reel moves in the case toward the island in the case and returns to the home position. As a result, the refueling hose is accommodated in the island, so that the refueling hose will not be caught by the vehicle or hinder the traveling until the next refueling.

Further, since the indicator is also provided on the same island provided with the nozzle hook, the indicator can be positioned in the flow line of the refueling operation, and the workability is improved.
