Description

Description: TECHNICAL FIELD The present invention relates to a liquid supply device in which a display device is provided on two opposing surfaces of a housing.

(Prior Art) For the purpose of effectively using the site of the gas station, the housings face each other 2
In a liquid supply device in which an indicator is provided on the surface and the front surface side and the rear surface side are oil supply areas, one to three liquid supply mechanisms are provided in one housing.

In such a liquid supply device, the liquid supply amount of each liquid supply mechanism is displayed on both front and back surfaces in order to indicate the liquid supply amount regardless of the position of the vehicle. For this reason, the indicator facing the side where the vehicle being refueled is stopped is effective, but the indicator on the opposite side is not effectively used. Especially 1
When the vehicles that have stopped in each refueling area are simultaneously refueled by a refueling device that has multiple refueling mechanisms on one housing, the other indicator on the same side can be used to refuel the other vehicle. Even the amount is displayed, which is a misunderstanding.

(Purpose) The present invention has been made in view of the above problems, and an object of the present invention is to prevent misinterpretation of the display and effectively use the display device to prevent a tedious customer from supplying a liquid. It is to provide a liquid supply device that can reliably transmit useful information and campaigns.

(Example) That is, the feature of the present invention is that two liquid supply mechanisms housed in the same box and two side surfaces of the box are connected to each liquid supply mechanism. Two nozzles, a display connected to each liquid supply mechanism and located two on each surface of the box, and a display switching means provided for each nozzle,
A nozzle switch for detecting whether the nozzles of the respective nozzles are hooked and unplugged, and a liquid supply mechanism connected to each liquid supply mechanism at the time of liquid supply, and the liquid supply amount and the amount related thereto are displayed on the display selected by the display switching means. Information not related to the liquid supply amount is displayed on the other display, and when a certain period of time elapses after it is detected that the nozzle is returned to the nozzle hook, all of the liquid supply mechanisms connected to each other are connected. The display device is provided with a signal switching means for displaying information not related to the liquid supply amount.

(Examples) Therefore, the details of the present invention will be described below based on illustrated examples.

1 and 2 show an embodiment of the present invention,
In the figure, reference numeral 1 is a double type metering device which accommodates two liquid supply mechanisms, and pumps 13, 13 'for pumping liquid to the liquid supply nozzles 12, 12' through hoses 11, 11 ', respectively. motor
A liquid supply mechanism consisting of 14, 14 'and flow meters 15, 15', and a flow meter
Two metering mechanisms I and II, which consist of flow rate pulse transmitters 16 and 16 'attached to 15 and 15', are housed. Dot matrix type display panels 6a, 6b, 6a ', 6b' for displaying data from a control device, which will be described later, are arranged on a front panel and a rear panel of the liquid supply device housing in total of four, respectively. Nozzle hooks 7 and 7'for locking the nozzles communicating with the respective measuring mechanisms are provided on the side wall of the housing, and as shown in FIG. 3, knobs 8a and 8a 'that can be operated from the outside are provided. Changeover switch 8 for connecting to and selecting a display form,

6b, 6a ', 6b' are selectively output.

FIG. 4 shows an embodiment of the above-mentioned control device, and since the two devices have the same function, the control device for one of the liquid supply mechanisms will be described. The flow rate pulse from the flow rate pulse transmitter 16 is counted. Counting calculation means 21 for calculating the liquid supply amount
An information storage means 22 for storing information not directly related to the liquid supply data such as a campaign sentence and road information, and a first signal switching means 23 for operating the signal from the changeover switch 8 to select display contents. , The signal from the first signal switching means 23 by the switching signal generating means 24 that outputs a signal by turning the nozzle switch 9 ON and OFF, and the signal that is emitted from the switching signal generating means 24 when the nozzle switch 9 is ON. Also, after the nozzle switch 9 is turned off, a signal from the information storage means 22 is selected and output to the double-sided display devices 6a and 6b by a signal issued from the switching signal generation means 24 after a predetermined time.
The signal switching means 25 is included. In the figure, reference numerals 26 and 27
Is a display drive means for outputting the signal from the second signal switching means 25 to the displays 6a, 6b, and 28 is a motor control means for driving the motor in response to the nozzle switch 9.

Next, the operation of the apparatus configured as described above will be described based on the flowcharts shown in FIGS.

If one vehicle stops at one side of the liquid supply device, for example, the A side, the salesperson confirms the position where the vehicle is stopped and selects the A side as the display surface by the changeover switch 8. (Fig. 6). Thereby, the output of the counting calculation means 21 is
In the route bc, the display 6a on the A side is connected to the information storage means.
The output of 22 can be output to the display 6b on the B side through the route a-d, and when the nozzle 12 is removed, the amount of liquid supplied to the display 6a of the liquid supply mechanism I on the side where the vehicle is located, Indicator on the other side
In 6b, information unrelated to the liquid supply data such as the campaign sentence is displayed from the information storage means 22.

On the other hand, in the liquid supply mechanism II in the rest state, the nozzle switch 9'is in the OFF state, so that the signal from the information storage means is output to the indicators 6a 'and 6b' via the second signal switching means, A campaign statement irrelevant to the liquid supply amount is displayed on the display devices 6a 'and 6b' on both sides of the liquid supply mechanism II.

Next, when one of the liquid supply devices, for example, the nozzle 12 on the I side is removed to start refueling, the nozzle switch 9 is turned on (a), and the previous liquid supply amount counted by the counting calculation means 21. Is reset to zero, the switching signal is transmitted from the switching signal generating means 24 to the signal switching means 25, and the display signal from the signal switching means 23 is displayed on the displays 6a and 6b via the display driving means 26 and 27.

That is, the display 6a displays the liquid supply amount from the counting calculation means 21, and the display 6b displays the information from the information storage means 22. At the same time, the pump 13 starts operating (b).

When the nozzle valve is opened and fuel is supplied in such a state, a pulse proportional to the liquid supply amount is output from the flow rate pulse transmitter 16 (c) and counted by the counting calculation means 21 to calculate the liquid supply amount ( D) is output to the display 6a. As a result, the driver can obtain information that is not related to his / her own liquid supply amount and the liquid supply amount displayed on the other side and on the indicator 6a ′ of the measuring mechanism II, such as traffic information, weather forecasts, campaign sentences, advertisements, etc. You will see. When a predetermined amount of liquid has been supplied and the nozzle 12 is hooked on the nozzle hook 7, the nozzle switch 9 is turned off (e) the motor 14 is stopped (f) and a certain time has elapsed (g), a switching signal generating means. A switching signal is output from 24 to the signal switching means 25, and the data in the information storage means 22 is displayed on each display 6
It will be output to a and 6b, and only the campaign text will be displayed (h).

When the nozzle 12 is removed again and the nozzle switch 49 is turned on within a fixed time, the process returns to (re) start.

It is assumed that while one vehicle is being supplied with the liquid, another vehicle is stopped on the other side, for example, the B side.

In this case, since the liquid supply mechanism I has already supplied the liquid, the liquid supply mechanism II will supply the liquid to the newly arrived vehicle.

Therefore, the salesperson operates the display changeover switch 8'to set the mode in which the liquid can be supplied on the B side. As a result, the oil supply amount of the measuring mechanism II is displayed on the display 6b 'on the B side and the information is displayed on the display 6a' on the A side.

According to this embodiment, even if two vehicles are simultaneously supplied with liquid, one indicator facing each vehicle displays only the amount of liquid supplied to that vehicle. Since the customer can be surely notified of the liquid supply amount and various information can be displayed on the other display, service to the customer can be improved.

FIG. 7 shows a second embodiment of the display device switching device. In the drawing, reference numeral 30 is a frame-shaped base body which constitutes a nozzle receiver, and liquid supply is provided on the left side surface and the right side surface thereof. A lever 31, which contacts the hose 11 when the hose is biased to the left or right,
32 is rotatably mounted, and limit switches 33 and 34 that respond to the movement of the lever are connected to each lever.

In this embodiment, when the nozzle is removed from the nozzle hook and the hose 11 is pulled to the side where the vehicle is located, the lever 31 (32) on the pulled side is displaced by being pushed by the hose 11 in this embodiment. The limit switch 33 connected to it.
(34) is activated to generate a signal.

Although the display device is selected by the switch in the above-mentioned embodiment, the same effect can be obtained even if vehicle detectors are provided on the front surface and the rear surface of the housing, respectively, and the signals are automatically switched. It is clear that it will play.

Further, in the above-described embodiment, a large amount of information is stored in the information storage circuit in advance, but the same effect can be obtained even if the display text is changed by a storage card or a keyboard that stores specific information. It is clear that it will play.

Further, in the above-mentioned embodiment, the information storage means 22 and 22 'are provided in each of the measuring mechanisms I and II, but it is clear that the same operation can be achieved even if they are commonly used.
