Abstract

PURPOSE:To make total oil feed amount readily available to an operator in order to facilitate the feeding operation at the time of a simultaneous oil feed to two tanks on the same track with two nozzles by providing a total amount indicator and a control device for indicating the total oil feed amount on its meter board when a shared switch is turned on. CONSTITUTION:There are provided two weighing systems A and B for one kind of oil in the housing 2 of a weighing machine 1a. A control device 15 is connected with a first and second indicator 13a and 13b for indicating the oil feed amounts of the systems A and B, a shared switch 14 for instructing the sharing of nozzles 10a and 10b and a total indicator 11 smaller in size than the indicators 13a and 13b indicating the total oil feed amount when the shared switch 14 is turned on and also connected with a POS 19. In the case of shared operator of these two systems, when the shared switch 14 is turned on before disengaging the first nozzle 10a, the control device 15 stores the operation of the second nozzle 10b and the sharing of these two nozzles 10a and 10b for control by a shared oil feed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a weighing machine installed at a filling station such as a gas station.

[Prior Art] In order to operate over long distances, large trucks are equipped with two 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 two nozzles are used to refuel each tank at the same time.

[Problem to be solved by the invention] When refueling two tanks of the same truck at the same time using two nozzles at a refueling station, the amount of refueling for each is displayed on the display of each nozzle, and for example, the amount of refueling is indicated by a customer requesting refueling. When the amount is instructed, it is necessary to refuel while adding up the two refueling display values, which is cumbersome.

In addition, since two slips are issued, it is possible to forget to request one slip or to make a mistake.6 This invention allows the total amount of fuel to be calculated when refueling two tanks of the same truck with two nozzles at the same time. The purpose is to provide a weighing machine that makes work easier by displaying it on hand.

[Means for Solving the Problems] According to the present invention, a total value display meter is provided, and when a common switch is turned on, the total oil supply amount is displayed on the total display meter.
Equipment is installed.

It is preferable that the measuring machine is configured such that two measuring systems of the same type of oil are provided in one housing, and parallel oiling can be performed by turning on a common switch.

It is preferable that the total value display meter is formed smaller in shape than a conventional single display meter, or has a different color to avoid misreading.

In addition, PO8 (on-site sales management device) is used as the control device for the weighing machine.
When the common switch is turned on, refueling is finished.
It is preferable to output a refueling end signal when both nozzles are hooked to the nozzle hook, and issue a single slip with the total amount of refueling.

[Operation] When the common switch is turned on in the measuring machine configured as above, the respective oil supply amount is displayed on the display meter of each nozzle, and the total value of the oil supply amount of both nozzles is displayed on the total value display meter. Is displayed.

Furthermore, the PO 8 issues one slip for the total amount of refueling when refueling is completed.

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

In Figure 1, there are two weighing fi
la, 1b and nozzle selection switch 1 on stand 16
7 and a card reader 18 are provided, and each is connected to Po5t9 provided in the office B. For example, each weighing machine v11a, 1b is adapted to be refueled with light oil, respectively.

In FIG. 2, the housing 2 of the meter 11a is provided with two metering systems A and B of the same type of oil. The metering system A includes a first pump 4a driven by a first motor 3a, and a suction pipe 5a and a discharge pipe 6a connected to an underground tank (not shown) are connected to the pump 4a. A flow meter 8a equipped with a first flow pulse transmitter 7a is provided on the discharge pipe 6a, and a hose 9a is connected to the tip thereof. This port 9a is provided with a first nozzle 10a. The housing 2 includes a nozzle 10.
A first nozzle switch 12a is provided for detecting that the nozzle a is removed from the housing 2.

The measurement system B is configured in the same manner as the measurement system A, and is provided with each device with a subscript "s". These devices are each connected to a control device 15. The control device 15 includes first and second indicators 13a and 13b that display the amount of oil supplied to the metering systems A and H, and nozzles 10a and 1.
A common switch 14 that instructs to share 0b, and a total display 11 that is smaller in size than the indicators 13a and 13b that displays the total amount of oil supplied when the common switch 14 is turned ON.
are connected to each other, and the control device 15 is connected to PO31.
9 is connected.

The weighing machine 1b has the same structure as the weighing machine 1a, and has subscripts c,
Each device is provided with the symbol d.

FIG. 3 is a control flowchart for selecting single use or shared use of the two refueling systems. When refueling, a refueling card is read by the card reader 18, and the nozzle selection switch 17 selects, for example, the first nozzle 10a. When switch "1" is pressed, card data and selected nozzle signals are input to the POS i9. Then, the movable signal for the first nozzle 10a selected from PO319 is sent to the control device!
f 15 (step S1), the control device 15
stores the movement of the first nozzle 10a (step 52)
2. When used alone, if you remove the first nozzle 10a without pressing the common switch 14, the first nozzle switch 12a
is turned on (step S3: NO, step S5: YES), and control is performed by independent refueling. In addition, in the case of shared use, turn off the shared switch 14 before removing the first nozzle 10a.
If N (step S3 is YES), the control device 15 also stores the movement of the second nozzle 10b, and both nozzles 10a, 1
The shared use of 0b is stored (step S4) and controlled by shared oil supply.

Step 520), based on this refueling end signal, the PO
In step S19, processing such as issuing a sent refueling amount slip is performed as will be described later. Note that in step S19, the second nozzle 1
If nozzle 0b is in use, the same process is performed when oil supply from the second nozzle 10b is finished and the second nozzle switch 12b is turned off. In addition, in the case of single use, since shared use is not stored in step 31g, the end of refueling is output to the POS 19 (step 521).Based on this signal of end of refueling, the POS 19 sends a signal as described below. Performs processing such as issuing slips for refueling amount.
