Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a refueling device installed at a refueling station for refueling automobiles and the like with gasoline.

[Conventional technology]

Among such refueling devices, the ground-fixed type has a refueling machine case set upright on an island installed on the ground.As one of the means for supporting the refueling hose extending outward from the refueling machine case, In order to prevent the weight of the refueling hose from being placed on the hand holding the refueling nozzle during refueling, an elastic support member such as a coil spring with an inverted U-shaped tip is installed upward from the refueling machine case, and this elastic There is a support member that inserts the refueling hose into the support member and supports the refueling hose vertically above the case.
Pull down the refueling hose against the elasticity of this elastic support member,
Insert the tip of the refueling nozzle into the car's refueling port.

[Problem that the invention seeks to solve]

In this way, the elastic support force from the elastic support member is always applied to the refueling hose, so the refueling hose is pulled upward not only when the refueling nozzle is lowered to the refueling port position, but also during refueling. is in a state of For this reason,
Refueling work is done while resisting this pull-up blade, and in order to pull out the refueling hose and to keep the refueling nozzle at the refueling port position after pulling it out, it is necessary to apply force to the hand holding it. Workability is not good. Furthermore, if the user removes his/her hand from the refueling nozzle while the refueling nozzle is inserted into the refueling port, the refueling nozzle may come off from the refueling port, which is dangerous. Furthermore, the conventional type has the disadvantage that the length of the refueling hose is limited.

An object of the present invention is to eliminate the disadvantages of the conventional example, and in particular, to prevent the hose from being pulled upwards when the refueling hose is pulled out or during refueling, making it easier to handle the refueling hose and improving workability. The purpose is to provide a refueling device that can be used even for long periods of time.

[Means for solving problems]

In order to achieve the above object, the present invention provides that a reel driving means is detachably connected to a reel for pulling up a hose, and the reel is rotated by the reel driving means upon receiving a refueling end signal.

[Effect]

According to the present invention, the refueling hose is not pulled upward during refueling by disengaging the hose pulling reel from the reel driving means during refueling. When the refueling end signal is input, the reel driving means and the hose pulling reel engage with each other, thereby pulling up the hose.

〔Example〕 Embodiments of the present invention will be described in detail below with reference to the drawings.

Fig. 1 is a vertical side view showing one embodiment of the refueling system of the present invention, and Fig. 2 is a front view of the same. First, the overall configuration of the refueling system will be explained. In the figure, 1 is on an island 2 installed on the ground. A vertically elongated refueling machine case is shown, and this refueling machine case 1
consists of a lower case 1a, a recess 1b for storing a refueling hose formed above the lower case 1a, and an upper case IC further above the lower case 1a, and an underground oil storage tank (not shown) as a refueling mechanism inside the lower case 1a. A fuel supply pipe 3 communicating with the fuel supply pipe 3 was set up, and a fuel pump 5 connected to a fuel supply motor 4 and a flow meter 7 connected to a flow rate pulse transmitter 6 were sequentially disposed in the middle of the fuel supply pipe 3.

Then, the end of the oil supply pipe 3 is inserted into the recess 1 for storing the oil supply hose.
A refueling hose 9 having a refueling nozzle 8 at its tip is led out into the lower case 1a, and the refueling nozzle 8 is housed in a nozzle hook 10 formed on the upper surface of the lower case 1a. This nozzle hook 10 is provided with a nozzle switch 11 that turns on and off in conjunction with the hooking and unhooking of the refueling nozzle 8.

According to the present invention, a rope 1 for pulling up the refueling hose is provided in the upper case IC provided above the recess 1b for storing the refueling hose.
A reel 13 for pulling up the refueling hose on which the fuel supply hose 2 is wound, and a hoisting motor 14 which is a driving means for the reel 13 are housed, and a clutch 15 is used to connect the rotating shaft 13a of the reel 13 and the rotating shaft 14a of the motor 14. Connected through. 16 in the figure is a solenoid for clutch operation.

Then, the row 112 wound around the reel 13 is pulled out from the lower part of the upper case IC, and a stopper 17 is installed on the way near the base of the hose 9 as shown in FIG.
a, and also connect the row 112 to the oil supply hose 9.
After attaching the end to the refueling nozzle 8 of the refueling hose 9
It is fixed to the stopper 17b attached to the side.

In this way, a control switch 18 for controlling the solenoid 16 is provided at the rope outlet end of the upper case IC, and the operator of the control switch 18 is engaged with the stopper 17a.

Further, a hoisting switch 19 is provided near the refueling nozzle 8 as a means for transmitting a refueling end signal.
9. A control device 20 using a microcomputer or the like is provided in the lower case la to receive output signals from the switch 1, the nozzle switch 11, etc., and thereby control the oil supply mechanism such as the oil supply motor 4.

Reference numeral 21 in the figure indicates a refueling amount indicator that projects horizontally from the side of the refueling hose storage recess 1b of the refueling machine case 1.

Next, the usage and operation will be explained with reference to the flowchart in Fig. 4. To refuel a car, first, the refueling nozzle 8
When it is removed from the nozzle hook 10, the nozzle switch 11 is turned on and stepped), a nozzle removal signal is sent to the control device 20, and the output from this is used to display the oil supply amount display 2.
The previous refueling amount displayed in step 1 is returned to zero (step port), and the refueling motor 4 is turned on and rotates, the solenoid 16 is energized, the clutch 15 is disengaged (step c), and the refueling hose is pulled up. The connection between the winding reel 13 and the winding motor 14 is released.

As a result, the reel 13 is in a state of free rotation, so if the refueling hose 9 is pulled downward in this state, the rope 12 whose end is fixed to it is also pulled together.
The reel 13 around which the rope 12 is wound rotates freely, and the refueling hose 9 can be pulled out with natural force.

Then, the refueling nozzle 8 is inserted into the refueling port of the gasoline tank of the automobile to perform refueling. At this time, since the holster 13 is still in a free state, there is no force pulling it upward on the refueling hose 9 or the refueling nozzle 8, and the refueling nozzle 8 can be inserted into the refueling port in a stable state. .

When refueling is completed, turn on the winding switch 19 provided near the refueling nozzle 8 and input the refueling end signal (
Step 2), the refueling pump motor 4 is locked, the solenoid 16 is de-energized, the clutch is connected, and the reel 1
3 and the winding motor 14 are connected, the winding motor 14 is turned on, and the reel 13 rotates (Step E).

As a result, the rope 12 is wound onto the reel 13, and the refueling hose 9 is also pulled up accordingly, and is wound into a loop shape by the stoppers 17a and 17b provided in the middle. When this stopper 17a is located at the end of the rope outlet and engages with the operator of the control switch 18, the control switch is turned on (step 1), thereby stopping the rotation of the hoisting motor 14. In other words, the winding of the refueling hose 9 is completed. In this way, the refueling hose 9 is wound up into a loop and is housed in the refueling hose storage recess 1b. Then, the refueling nozzle 8 is hung on the nozzle hook 10, and the refueling work is completed.

1. In this embodiment, the winding motor 14 is used as a driving means for the reel 13, but in another embodiment, a spring can be used as shown in FIG. 5.

In this case, the rotating shaft 13a of the refueling hose pulling rope 13 and the rotating shaft 22a connected to the mainspring 22 are connected via a gear 23, and the solenoid 24 for locking the mainspring 22 is engaged with the gear 23. Ta. In this embodiment, the control switch 18 used in the first embodiment is unnecessary, and other components are the same as those in the first embodiment, so the same reference numerals are given and detailed explanations are omitted.

Next, the usage and operation will be explained with reference to the flowchart of FIG. 6. When the refueling machine is not in use, the mainspring 22 is not wound and the locking solenoid 24 is also in a released state.

When refueling, when the refueling nozzle 8 is removed from the nozzle hook 10, the nozzle switch 11 is turned on (stepped), and the nozzle removal signal from here is input to the control device 20, and the control device 20 acts on the refueling amount indicator 21. The refueling motor 4 is turned on at the same time as the displayed previous refueling amount is reset to zero (step 1).

Then, when the refueling hose 9 is pulled, the low 112 is also pulled together, the reel 13 rotates, and the rotation shaft 13a1 gear 2
3. The rotation of the reel 13 is transmitted to the mainspring 22 via the rotating shaft 22a, and the mainspring 22 is wound.

In this way, when refueling is started by pulling out the refueling hose 9 and inserting the refueling nozzle 8 into the refueling port of the gasoline tank of the automobile, the flow rate of the oil pumped from the underground oil storage tank to the refueling pipe 3 by the refueling pump 5 is the flow rate. The flow rate is measured by a total of 7, and is output from the flow rate pulse transmitter 6 to the control device 20 as a flow rate pulse signal.

Upon receiving this flow rate pulse signal, the control device 20 determines that refueling has started (STEP), and the output from this device energizes the locking solenoid 24 to prevent rotation of the gear 23 (STEP). As a result, the mainspring 22 remains wound up and is not unwound, so no force is applied to the refueling nozzle 8 or the refueling hose 9 to pull it up during refueling.

In addition to the above-mentioned flow rate pulse signal, the signal for determining the start of refueling may be a detection signal from an insertion sensor that detects insertion of the refueling nozzle 8 into the refueling port, or a separate refueling start switch. may be provided in the refueling nozzle.

When refueling is finished, turn on the winding switch 19 provided near the refueling nozzle 8 and input the refueling end signal (stellar pull), the refueling pump motor is locked (Step 2), and the locking solenoid 24 is energized. is released, the gear 23 is unlocked, the mainspring 22 works, the reel 13 rotates, and the rope 12 wound around it is wound up.

As a result, the refueling hose 9 is pulled up and the stopper 17
When the rope a is engaged with the rope outlet formed on the lower surface of the upper case 1c, the stopper 17a prevents the rope 12 from being wound up any further, so the refueling hose 9 is inserted into the refueling hose storage recess 1b in a loop shape. It will be rolled up and stored here.

Then, the refueling nozzle 8 is returned to the nozzle hook 10 to complete the refueling operation.

Note that the means for transmitting the refueling end signal is not limited to the above-mentioned winding switch, and a refueling port insertion sensor provided in the refueling nozzle 8 may also be used as another means. These fuel filler insertion sensors include those that use phototra, such as Kouni's, which takes advantage of the difference in brightness between the inside and outside of the gasoline tank, those that detect the capacitance of the car, and those that detect the capacitance of the car, or those that detect the electrostatic capacity from the gasoline tank. A system that detects gasoline paper is considered, and in either case, it detects that the refueling nozzle 8 has been pulled out from the refueling port of the gasoline tank, and uses this detection signal as the refueling end signal.

〔Effect of the invention〕

As described above, in the refueling device of the present invention, the refueling hose and the refueling nozzle are easy to handle and work because no force is applied to the refueling hose to wind it up during refueling.

Furthermore, since the refueling nozzle is not pulled upward and removed from the refueling port during refueling, there is no risk that the oil discharged from the refueling nozzle will be scattered around, thereby improving safety. Furthermore, since the refueling hose can be rolled up, even long refueling hoses can be used.
