Abstract

PURPOSE:To facilitate an oil feeding operation by providing two counting systems of the same kind of oil in a housing and providing small indicators in respective nozzles of said counting systems and providing controllers indicating the total quantity of fed oil on said indicators by means of a common switch turned on. CONSTITUTION:Two sets of counters 1a, 1b, a nozzle select switch 17 and a card reader 18 on a stand 16 are equipped, when a common switch 14 is turned on before a first nozzle 10a is undone in case of common use, a controller 15 memorizes the movement of a second nozzle 10b and controls common oil feed operation with the memory of common use of both nozzles 10a and 10b. When the common use is memorized with the common switch 14 turned on, it flow pulses are input from transmitters 7a, 7b of both flow pulses, both pulses are added up and the aggregate is indicated at counters 11a, 11b of both gripps and output on POS.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is applicable to gas stations installed at gas stations and other filling stations. Regarding i machine.

[Conventional technology] Large 1-racks are designed for long-distance operation, so they are used in the human world! l(
It is equipped with two fuel tanks (for example, 200 liters).

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.

SUMMARY OF THE INVENTION An object of the present invention is to provide a weighing machine that facilitates the operation by displaying the total amount of refueling at hand when simultaneously refueling two tanks of the same truck with two nozzles.

[Means for Solving the Problems] According to the present invention, two measuring systems of the same oil type are provided in one housing, a small indicator is provided in the nozzle of each measuring system, and when the common switch is turned on, Each display meter is equipped with a control device that displays the total amount of oil supplied.

In addition, if a POS (on-site sales management device) is connected to the control device of the weighing machine and the common switch is turned on, a refueling end signal is output when refueling is finished and both nozzles are hooked to the nozzle hooks, and the amount of refueling is It is preferable to configure the system so that a single slip is issued, which is a total of the following.

[Function] In the measuring machine configured as described above, when the common switch is turned on and oil is supplied by two nozzles, the control device displays the total amount of oil supplied on the small display meters of both nozzles.

Furthermore, the POS issues one slip for the total amount of refueling at the end of refueling.

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

In Figure 1, there are two weighing machines 1 on site A of the gas station.
a, 1b, and the nozzle selection switch 17 on the stand 16
and a card reader 18, each of which is connected to a Po5t9 installed in the office B. For example, six in total, 11flla and 1b, are each supplied with light oil.

In FIG. 2, the housing 2 of the measuring machine 1a is provided with two measuring systems A and B for 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 hose 9a is provided with a first nozzle 10a, and the nozzle 1.0a is provided with a first hand-held counter lla that displays the amount of oil supplied.

The housing 2 includes a first nozzle switch 12a that detects when the nozzle 10a is removed from the housing 2.
is provided.

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 sharing of 0b is connected to each, and a control device 15 is connected to the PO 319.

Weighing machine 1b is configured similarly to weighing machine 1a, and has subscripts c and d.
Each device is provided with the symbol.

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 reader and selection nozzle signals are input to POS 19. Then, the movable signal of the first nozzle 10a selected from PO319 is transmitted to the control device 1.

), controlled by independent lubrication. In addition, in the case of shared use, if the common switch 14 is turned on before removing the first nozzle 10a (step S3 is YES), the control device 15 also remembers the movement of the second nozzle 10b, and both nozzles 10a, 10b
(step S4), and is controlled by the shared oil supply.

0a is removed and the first nozzle switch 12a is turned on (step 5io), the movement of the first nozzle 10a is stored as shown in step S2 in FIG. 3 (step 511), and as shown in step S4. If shared is stored in (step 312), if the second nozzle 10b is still on and the second nozzle switch 12b is off (step 513), the previous total count value is returned to zero, and the hand counter lla ,llb return to zero (step 514
), the previous individual count value is returned to zero, and the first display 1
The previous oil supply amount of 3a has returned to zero, and the first pump motor 3a is turned to O.
N to enable refueling (step 515). If the nozzle is not shared (step 512), the process goes to step S14; furthermore, if the second nozzle is already removed even if it is shared (step 513), step S15 becomes. Then, the valve of the first nozzle 10a is opened and refueled, and when the refueling is finished, the first nozzle 10a is turned on, and the first nozzle switch 12a is turned off (step 516).
The first pump motor 3a is set to 0FFL, the movable memory of the first nozzle 10a is canceled, and refueling is not possible even if the first nozzle 10a is removed again (step 517).

In the case of shared use, the shared use is stored in step S4 (step 318), and if the second nozzle 10b is applied and the second nozzle switch 12b is turned off (step 519), the control device 15 The end of refueling is output to PO319, the shared memory is canceled, and the second nozzle 10b is shared, in case the second nozzle 10b is not used.
The movement of 0b is released (step 520). Based on this signal indicating the end of refueling, the PO 319 performs processing such as issuing a slip for the amount of refueling that has been sent as described later. Note that if the second nozzle 10b is in use in step S19, the second nozzle tab The same process is performed when the second nozzle inch 12b becomes OFF after the refueling from Output to POS 19 (step 521).

Based on this signal indicating the end of refueling, the POS 19 performs processing such as issuing a sent slip for the amount of refueling, as will be described later.

FIG. 6 is a control flowchart for counting and displaying both flow rate pulses during shared use, and is step S4 in FIG.
As shown in FIG. 3, when the common switch 14 is turned on and common is stored (step 530), if flow pulses are input from both flow pulse generators 7a and 7b, both pulses are counted and summed. Add the total value to the counter ILa on both hands,

[Effects of the Invention] Since the present invention is configured as described above, when refueling two tanks of the same truck at the same time, it is possible to refuel by checking the total amount of refueling on the counter at hand. It can make your work easier.

Moreover, one slip for the total amount of oil supplied can be issued to facilitate the settlement process.

In addition, one tlIi has the functions of two conventional machines,
Installation space can be saved.
