Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to an oil supply device having at least two oil supply systems in one case.

[Prior Art] A so-called multi-product dispensing system is known in which the number of refueling points is increased at refueling stations such as gas stations in order to effectively utilize narrow premises. In this technique, at least two oil supply systems are provided in one case, and each type of oil can be supplied to the system.

However, according to the prior art, two fuel supply systems that share a display are installed in one case, so space and the like are not saved much.

[Object of the Invention 1 Accordingly, an object of the present invention is to provide an oil supply device with a reduced number of parts by allowing common parts to be shared.

[Configuration of the Invention] According to the present invention, two pumps are drivingly connected to one motor via a clutch.

[Operations and Effects of the Invention] Therefore, since each pump of the two oil supply systems is driven by one motor, the space for one motor is saved. This is particularly effective in a so-called single-sided refueling device in which an indicator is provided only on one side, since refueling is not performed simultaneously from two refueling systems.

[Preferred embodiment] When carrying out the present invention, a one-way clutch is used as the clutch, and the pump drive shaft is connected to the rotating shaft of the motor via the clutch, and by rotating the motor in forward and reverse directions, either one of the pumps can be operated. It is preferable to drive only the By doing this, each pump can be suitably driven with a simple control device, and an electromagnetic clutch can also be used as the clutch.

Further, in implementing the present invention, one indicator for the two fuel supply systems can be shared.

[Example] The present invention will be described in detail below with reference to the drawings.

The illustrated embodiment is an example in which two nozzles can selectively supply two liquids, and one indicator is used in common.

FIG. 1 shows a refueling device embodying the present invention, the whole is indicated by the symbol C in the figure, and the refueling case is a lower case C1,
An upper case C2 provided above the upper case C1,
A top case C provided further above the upper case C2
It consists of 3.

As is well known, the lower case C1 houses necessary equipment such as a pump, a motor, and a diversion 51.

In addition, the upper case C2 includes an indicator 1D, refueling indicator lamps L1 and L2 on each side, and one nozzle on each side.
2 and 1 are played in and. The two-part case can also be equipped with a card reader, keyboard, etc. Also, the neck restraint can be installed at any position on the upper case or the lower case.

The top case C3 is provided with display panels 13a and 13b that display the type of oil, such as "high octane", "regular", etc., and on the small side of each end there is a hose connection part that communicates with an oil supply pipe extending from a flow meter (not shown). R1, R2 are provided, one end of each hose H1, 1-12 is connected to the hose connection part R1, R2, and the (
l! ! +g are connected to nozzles N1 and N2, respectively.

As shown in FIG. 2, motor shafts 1a and 1b extending on both sides of the motor M are respectively connected to pumps Pi and R2 via one-sided clutches 2a12b. The pumps Pi and R2 pump oil, for example, pump P1 pumps high-octane gasoline and pump P2 pumps regular gasoline from a tank (not shown), and pumps the liquid into the pipe 3.
a, 3b to the flow meters 48, 4b, and the first
As explained in the figure, the liquid is sent to the respective nozzles N1 and N2 via the hoses H1 and N2.

In the illustrated embodiment, the motor M is controlled by the motor control circuit 5, that is, forward rotation, reverse rotation, and stop.
In the case of reverse rotation, pump P2 is driven via clutch 2b. The total flow is 4a, 4
Diversion pulse transmitters 6a and 6b are respectively provided at b, and these diversion pulse signals are input to a word count circuit 7, so that the flow rate is displayed on one display ID.

This type of lubrication device cannot lubricate two liquids at the same time.
When one ura is being refueled, the other is not.

The control will be explained below mainly with reference to FIGS. 2 and 3.

1 for each nozzle, nozzle switch S for each K2
W1 and SW2 are provided, and when one nozzle N1 is removed, the nozzle switch SW1 is turned on, and the other nozzle N1 is turned on.
When 2 is removed, the nozzle switch SW2 is turned on.

Now, when the nozzle N1 is removed from the nozzle hook 1 in order to refuel with high-octane gasoline, a signal is applied from the nozzle switch SW1 to the motor control circuit 5, the one-shot 1-multivibrator 10b, and the inverter 8a. Therefore, the signal from inverter 8a to AND circuit 9a disappears. As shown in FIG. 3, in the motor control circuit 5, when the nozzle switch SW1 is turned on, the relay R1 is activated, its contact R1b is closed, the motor M rotates forward, and the high-octane gasoline pump P1 is driven. and contact R1a
This prevents malfunction when the other nozzle switch SW2 is idle. Further, when a signal is applied to the one-shot multi-vibrator 10b, the nozzle switch SW
2 is off, and the inverter 8b passes the signal to the AND circuit 9b.
, the AND circuit 9b applies a return signal to the counting circuit 7, and as a result, the previous oil supply amount of the counting circuit 7 is reset to 1-, and the display becomes zero. . When oil is supplied from the nozzle N1 in this manner, the 51 measured value of the flow meter 4a is counted to 31 by the counting circuit 7 and displayed on the 1 display ID. When the refueling is finished and the nozzle N1 is hooked to the nozzle hook 1, the motor M is stopped.

Even if nozzle N2 is removed from nozzle hook 2 while refueling from nozzle N1, contact R1 is closed even if nozzle switch SW2 is closed.
a is open, relay R2 does not move, its contact R2a does not open, its contact R2b does not close, and motor M does not malfunction.

Further, even if a signal is transmitted from the one-shot multivibrator 10a to the AND circuit 9a, since there is no signal from the inverter 8a, a return signal will not be output from the AND circuit 9a, so no problem will occur.

[Summary] As described above, according to the present invention, one motor is connected to two pumps via a clutch to drive them, so only one motor is required, and the device can be simplified. . Controlling it is easy if it rotates in forward and reverse directions! It is 11. However, for example, the clutch may be used as an electromagnetic clutch to avoid on/off operation.
