Description

TECHNICAL FIELD The present invention relates to a refueling device with an electronic display device.

(Prior art) With the development of credit cards in recent years, the form of commercial transactions has expanded to cash transactions, credit sales as well as credit sales. Showa 57-
As shown in Publication No. 194994, there is a refueling device that displays "Cash" on a special display in case of cash payment to prevent forgetting to receive sales proceeds, and also Japanese Patent Application Laid-Open No. 1983- As shown in Japanese Patent No. 20133, an oil supply device equipped with a special indicator for displaying the type of oil has also been proposed.

According to these devices, the payment method and oil type are displayed on a dedicated display separate from the fuel amount display, which not only poses a risk of oversight for inexperienced customers. However, there is a problem in that the number of display devices increases, which requires time and effort for assembly and maintenance.

The present invention has been made in view of these problems, and its purpose is to proactively utilize the period when the display is inactive from the time the nozzle is removed until the start of refueling, and to improve the payment method. It is an object of the present invention to provide a new oil supply device that can display oil type and oil type.

(Objective) In view of the above circumstances, the present invention provides a refueling device that can minimize troubles during commercial transactions by appropriately displaying information necessary for buying and selling fuel oil. The purpose is to

(Means for Solving the Problems) In order to solve such problems, the present invention provides a nozzle switch that outputs a signal when the refueling nozzle connected to the refueling pump via a hose is removed from the main body, and a display screen. a dot-shaped display means formed by arranging display elements in a matrix, an oil supply amount calculation means for calculating the oil supply amount based on the flow rate signal, an oil type storage means in which the oil type is stored in advance, and payment method data. a card reading means for reading data from a card-like storage medium storing a card; a card content storage means for identifying a payment method based on the data from the card reading means and outputting it to the display means; When a signal is output from the nozzle switch, the oil type of the nozzle removed from the nozzle hook is read from the oil type storage means and output to the display means, and when a predetermined time has elapsed, the oil supply amount calculation means The apparatus further includes a display switching means for outputting data from the display to the display means.

(Operation) When the card-like storage medium is read by the card reading means prior to refueling operation, the card content storage means determines the payment method stored in the storage medium and causes the display means to display the payment method. Next, when the nozzle is removed from the nozzle hook and a signal is output from the nozzle switch, the display content switching means outputs the oil type data stored in the oil type storage means to the display means. As a result, the payment method and oil type are displayed on the display means for displaying the amount of oil supplied, so both the salesperson and the customer can confirm the payment method and oil type. When a predetermined time required for confirmation has elapsed, the display switching means outputs the data from the oil supply amount calculating means to the same display means to display the oil supply amount. Therefore, important data can be switched and displayed on the same display means, making it extremely easy to check the data.

(Example) The details of the present invention will be described below based on illustrated examples.

FIG. 1 shows an embodiment of the present invention, and reference numeral 1 in the figure is a control device which is a characteristic part of the present invention, and as shown in FIG. A counting means 1a that integrates the flow rate signals from the transmitters 2 and 3, a card content storage means 1b that stores data from a card reader 4 provided on the outer surface of the fuel supply device main body 10, and a first and second nozzle switch 5. , 6 are turned on, first and second oil type data output means 1c and 1d output corresponding oil type data;
It is comprised of a switching means 1e for selecting signals from the output means 1a to 1d, and a drive means 1f for driving the display panel 7. In addition, the code 1 in the figure
g and 1h are nozzle switches 5 and 6, respectively.
First and second motor control means that operate the first and second pumps 8 and 9 when turned on are shown.

Returning again to FIG. 1, the reference numeral 7 in the figure is the dot matrix type display panel described above, which is mounted so that its display surface is exposed on the outside of the 10 fuel supply devices. It displays data.

Reference numerals 11 and 12 are oil supply mechanisms that communicate with combustion oil tanks of different oil types A and B, respectively, and motors 8 and 12 are operated by turning on the oil supply switch provided on the nozzle.
Fuel oil from pumps 8a and 9a driven by pump 9 is sent to respective nozzles 15 and 16 via flowmeters 13 and 14, respectively. Note that reference numerals 17 and 18 in the figure indicate nozzle hooks attached to the main body of the oil supply device.

Next, the operation of the apparatus configured as described above will be explained based on the flowchart shown in FIG.

When the credit card submitted by the customer is inserted into the card reader 4 prior to refueling and the card data is read, the card content storage means 1b detects the type of card and displays it on the display panel 7. Once these preparations have been completed, the oil type specified by the customer,
For example, when the nozzle 15 corresponding to oil type A is removed from the nozzle hook 17, the first nozzle switch 5 is turned on.
becomes. A signal from the first oil type output means 1c is detected and oil type A is displayed on the display panel 7 (FIG. 4A). At the same time, the previous oil supply amount count stored in the counting means 1a is reset to zero.

In this way, after displaying for a time, for example, several seconds, allowing both the service person and the customer to confirm the conditions that are the prerequisites for the transaction, "00" is displayed (FIG. 4B). Once these preparations have been completed, oil type A
The refueling mechanism 11 starts refueling. As a result, the first pulse oscillator 2 outputs a pulse signal. The counting means 1a displays the counted contents on the panel 7 while integrating and displaying the pulse signals. In this way, the predetermined amount of oil supply is completed, and the nozzle 15
When the nozzle hook 17 is set and the first nozzle hook 5 is turned off, the operation of the oil supply mechanism 11 is stopped. Needless to say, the same operation is performed when refueling with oil type B.

In addition, in the case of a refueling device equipped with a preset means, when the specified amount of refueling is applied, the refueling mechanism is stopped, and at the same time, the message "P-stop" is displayed on the display panel to notify customers and service personnel. It is possible to notify the operator that the specified amount of refueling has been completed (Fig. 4 C).

Furthermore, it is possible to appropriately detect and display troubles such as instantaneous power outages and overheating of the pump drive motor that occur during refueling work.

In addition, in this embodiment, explanation was given using an example of a refueling device in which the refueling amount display panel is used for multiple refueling mechanisms, but an independent type in which one display panel is provided for one refueling nozzle is also applicable. Needless to say, the same effect can be achieved even if applied.

(Effects) As explained above, the present invention includes a nozzle switch that outputs a signal when the refueling nozzle connected to the refueling pump via a hose is removed from the main body, and display elements arranged in a matrix on the display surface. A dot-shaped display means, an oil supply amount calculating means for calculating the oil supply amount based on the flow rate signal, an oil type storage means in which the oil type is stored in advance, and a card-shaped storage medium storing payment method data. a card reading means for reading a card; a card content storage means for identifying a payment method based on data from the card reading means and outputting it to a display means; and display switching means for reading out the oil type of the nozzle removed from the nozzle hook from the oil type storage means and outputting it to the display means, and outputting the data from the oil supply amount calculation means to the display means after a predetermined time elapses. Therefore, when the card-like storage medium is read by the card reading means before refueling, the payment method is displayed on the display means, and when the nozzle is removed from the nozzle hook, the nozzle that has just been removed is displayed. The oil type is read out from the oil type output means and displayed on the same display means that displays the payment method, so that the customer can confirm the payment method and oil type in advance, and also when the refueling operation has started. The amount of refueling can be displayed on the display means that previously displayed the payment method and oil type, and important data can be aggregated and displayed on the same display means, thereby making it easier to confirm information. Not only this, but also the number of display panels can be reduced by displaying many types of information on the same display means.
