Abstract

PURPOSE:To improve oil feeding efficiency for a large-size vehicle by providing each oil feed system with its own preset means in an oil feeder having a common oil feed control device. CONSTITUTION:In the case of preset oil feedings effected commonly to a single truck on the side C of an oil feeding area, when a card reader 22 reads the oil feed card, a control device 14a sends the read card data through a common oil feed control device 30 into POS 15. Upon entry of a card collating signal from the POS 15, the movement of a nozzle 10a is stored. When a common switch 19 on the side C of the oil feeding area is depressed, indicating meters 13a and 13c on the side C are lighted to inform the common oil feed control device 30 as to the common use of oil feeders for feeding on the side C. When a common use signal is inputted from the control device 14a, the common signal is supplied into the other control devices 14b and 27. When flow amount pulses are inputted from the control devices 14a and 14b at the start of oil feed, added flow amount pulse signals are sent into the control device 27 and the POS 15. Upon entry of oil feed termination signals from the control devices 14a and 14b, the POS 15 makes out a sheet of slip with the total amount of the oil fed by both the oil feed systems printed thereon.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention incorporates multiple sets of refueling systems of the same type of oil installed at refueling stations such as gas stations into one case, and provides a shared refueling control device. This invention relates to a refueling device.

[Prior Art] In order to operate over long distances, large trucks are equipped with two to three large capacity (for example, 200 liters) fuel tanks.

When refueling such a truck at a refueling station, refueling each tank with one nozzle takes time and effort, so multiple nozzles are used to refuel each tank at the same time.

When refueling different tanks of the same truck at the same time using multiple nozzles at a refueling station, each refueling amount is displayed on the display meter of each refueling system.For example, when a refueling staff is instructed by a customer to refuel, It is necessary to add up the displayed values while refueling, which is cumbersome.

Therefore, in Japanese Patent Application No. 63-223636, the applicant of the present invention proposed a refueling device that is equipped with a total value display meter and a control device that displays the total amount of oil supplied on the total value display meter when a common switch is turned on.

[Problems to be Solved by the Invention] Although this proposal itself is effective, it does not allow preset lubrication.

SUMMARY OF THE INVENTION An object of the present invention is to provide a refueling device in which a plurality of sets of the same oil type refueling systems capable of preset refueling are incorporated into one case, and a shared refueling control device is provided.

[Means for Solving the Problems] According to the present invention, in a refueling system in which a plurality of sets of refueling systems of the same oil type are assembled into one case and a shared refueling control device is provided, a presetting means is provided for each refueling system. It is set up.

The presetting means is composed of a keypad equipped with a numeric keypad, a refueling card reader, and a common switch for selecting whether to use both refueling areas. Preferably, each pad is provided near the top of the nozzle hook.

In addition, the case is installed on an island, the refueling areas are placed on both sides of the island, the display meters for each refueling system are installed on the respective refueling area sides of the case, and the display meters for the total value display are placed in each refueling area. Furthermore, when one refueling area side selects shared use using the control device, the display of each indicator on the other refueling area side is turned off.
It is preferable to perform control so that the display is turned off when refueling is completed.

[Function] In the lubrication system configured as described above, if you select shared use on one lubrication area and perform preset lubrication on both lubrication systems, each display will be displayed on both indicators on the selected lubrication area. The amount of refueling is displayed, and the total amount of refueling is also displayed on the total display meter. At this time, the display on each indicator on the other refueling area side is turned off, and when refueling is completed, the display is turned off.

[Example] An example of an oil supply system in which two sets of oil supply systems of the same oil type are incorporated into one case will be described below with reference to the drawings.

In Figure 1, refueling equipment 1 on the island of the refueling station

The control device 14a includes a display meter 13ac that displays the amount of oil supplied.
, 13ad, a keypad 16a (hereinafter referred to collectively as 16), a main valve 26a1, a flow rate pulse transmitter 7a1 motor 3a, and a nozzle switch 12a are connected to each other, and a control device rl1 1 4 a
is connected to the common fuel supply control device 30, and the device ffi 30 has a total display meter 11c that displays the total fuel supply amount when the common switch 19 or 20 of the keypad 16 is pressed, a control device 27 of the lid, and a control device 27 in the office E. It is connected to the provided POS 15.

The oil supply system B is configured in the same manner as the oil supply system A, and is provided with each device labeled with the suffix b, and the suction pipe 5b is branched from the suction pipe 5a.

In FIG. 2, a refueling device 1 is installed on an island I.
In case 2, the display totals 1 3 a 8% 1 3 a dz13b are displayed toward the refueling area C1D on both sides.
Similarly, a total display total 11c1lid is provided on both sides of both areas C and D.

In FIG. 3, the keypad 16 includes a numeric keypad 17,
A display 18 that displays the preset amount, common switches 19 and 20 that select whether to share the nozzles 10a and 10b when refueling in the refueling area C or D side, and a card reader 22.
A setting switch 21 and the like are provided.

Figure 4 shows the control device 14 on the fueling system A side for card reading, fueling area selection, common selection, and presetting.
FIG. 3 is a control flowchart of FIG.
When refueling a truck parked on the side in a shared preset manner, when a refueling card is read with the card reader 22 of the keypad 16a (step S1), the control device 14a stores the read card data. A card verification signal is input from the POS 15, and if the signal indicates that refueling is possible (step S3), the movement of the nozzle 10a is memorized (step S2). S4). Note that if refueling is not possible (step S5
), do the same thing with another card. Next, nozzle 1
If you press the common switch 19 on the refueling area C side (step S7) before removing 0a (step S6), the refueling area D
The indicator 13ad on the side is turned off, the indicator 13ac on the C side is turned on, and the shared fueling control device 30 is notified of the C side sharing (step S8). In addition, when performing shared refueling on the refueling area D side, if the shared switch 20 is pressed (step S,), the same process as step S8 is executed (step S, .), and when refueling is performed by the refueling nozzle 10a alone, In step S6, if the refueling nozzle 10a is removed from the nozzle hook without pressing the common switch and the nozzle switch 12a is turned on, it is independently controlled.

Next, when the numeric keypad 17 of the keypad 16a is pressed to input the desired amount of oil to be supplied from the oil supply nozzle 10a side (step S++), it is displayed on the display 18 (step SI2).
When the setting switch 21 is pressed (step S+t), the preset value is set and stored (step S14). In addition, if the preset lubrication is not used, do not set the lubrication nozzle 10.
If a is removed (step S, 5), normal lubrication is performed.

Furthermore, if the shared use operation is performed on the keypad 16b on the fueling system B side before reading the card in step S, the shared fueling control device 30 is activated in step S33 of the control flowchart of FIG. Since the signal for common use on the C side is being inputted from (step S, 6) or the signal for common use on the D side is being input (step SI7), the movement is memorized based on that signal, and the display meter is turned off or turned on. (Steps 818% to 819), the process moves to step 311.

Note that the control flowchart of the control device 14b on the oil supply system B side is also the same, so the explanation will be omitted.

When a pulse signal is input from the flow rate pulse transmitter 7a of the flow meter 8a (step S24)
), is counted and displayed on the display meter 13ac, and further sends a flow rate signal to the shared oil supply control device 30 (step S2,). When the oil supply amount reaches the preset value (step S26), the main valve 2
6a is closed (step S27), the nozzle 10a is hung on the nozzle hook, and the nozzle switch 12a is turned off (
Step S28), the pump motor 3a is turned OFF, the main valve 26a is opened, the preset amount display on the display 18 of the keypad 16a is erased, the movement memory is also erased, and even if the nozzle 10a is removed again, refueling is not possible. , outputs the end of refueling to the shared refueling control device 30 (step S29).

It should be noted that before removing the nozzle in step S21, the information as described in step S38 of FIG. 5 is sent from the shared oil supply control device 30. If a signal to erase the movable nozzle is received, that is, if refueling is completed without using one nozzle even though the nozzle is shared (step S3o).
