Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refueling device, and more particularly to a refueling device configured to perform self-service refueling of a refueled tank by a weighing machine having a plurality of refueling systems.

[0002]

2. Description of the Related Art Conventionally, a weighing machine dedicated to kerosene is a weighing machine fixed to the ground, and like a weighing machine for gasoline or light oil, a flexible oil supply hose derived from the weighing machine, A refueling nozzle provided at the tip of the refueling hose and inserted into the refueling port of the plastic container.

However, in the conventional refueling apparatus, refueling is performed with the plastic container placed on the ground, so that the operator must bend his hips and operate the refueling nozzle, making it difficult to perform the refueling operation. In order to solve such inconveniences, there is a method of refueling by supporting the refueling nozzle so as to be able to move up and down, or a method of refueling by inserting a refueling pipe extending downward from the side of the weighing machine into a refueling port of the plastic container. Is being developed.

Further, when card data (refueling amount or refueling amount) of a prepaid card is read in advance by a card reader, a refueling amount for one refueling system is preset, and refueling is performed only while the refueling operation button is pressed. A refueling device having a self-service refueling function has been developed. In this refueling device, when the refueling operation button is pressed, the solenoid valve is opened (or the pump is started).
Then, refueling is started, and when the pressing operation of the refueling operation button is released, the solenoid valve is closed (or the pump is stopped) and the refueling is stopped.

[0005]

However, in the refueling apparatus that performs self-service refueling as described above, when card data (refueling amount or refueling amount) of a prepaid card purchased in advance is read by a card reader, one of the following is obtained. Since the refueling permission for the refueling system is output and the refueling amount is preset, even when refueling a plurality of plastic containers, the plastic container is refueled using only the refueling system on one side of the weighing machine.

[0006] Therefore, when performing self-service refueling, a plurality of plastic containers must be refueled one by one, so that there is a problem that it takes a long time from the start of refueling to the plurality of plastic containers to the end of refueling. In addition, in order to refuel a plurality of plastic containers in one refueling system, it is necessary to replace the filled plastic container and the pre-refueled plastic container at a predetermined position of the weighing machine. There is also a problem.

[0007] Therefore, an object of the present invention is to provide a refueling device that solves the above-mentioned problems.

[0008]

The present invention has the following features to solve the above-mentioned problems. According to the first aspect of the present invention, there is provided input means for inputting refueling amount data corresponding to an amount or amount to be refueled, a plurality of refueling systems for refueling a refueled tank, and input from the input means. Control means for controlling refueling of the refueling tank by the refueling system based on refueling amount data, when refueling amount data corresponding to the capacity of a plurality of refueling tanks is input from the input means. And a refueling permission setting means for giving refueling permission to the plurality of refueling systems.

Therefore, according to the first aspect of the present invention, when the refueling amount data corresponding to the plurality of refueling tanks is input from the input means, the refueling permission is given to the plurality of refueling systems. When there are a plurality of refueling tanks, refueling can be performed simultaneously by a plurality of refueling systems, so that the time from the start of refueling to the end of refueling of all refueling tanks can be reduced.

[0010] According to the second aspect of the present invention, the first aspect is provided.
The refueling device according to claim 1, further comprising a detection unit configured to detect the refueling tank placed at a predetermined position to be refueled by the plurality of refueling systems, wherein the refueling permission setting unit determines a detection result by the detection unit. A fuel supply permission is selectively given to the refueling system on which the lubricated tank is mounted among the plurality of refueling systems based on the refueling system.

Therefore, according to the second aspect of the present invention, the refueling permission is selectively given to the refueling system on which the refueling tank is mounted among the plurality of refueling systems based on the detection result by the detecting means. It is possible to prevent liquid supply to a refueling system where no lubricated tank is mounted, and to simultaneously lubricate a plurality of lubricated tanks to be refueled by mounting them at predetermined positions in a plurality of lubrication systems. Refueling time to the refueling tank can be reduced.

The weighing machine 12 is provided with an input device 50 composed of, for example, a numeric keypad for inputting the refuelable capacity of the plastic container 32 to be refueled before refueling. FIG. 6 is a block diagram illustrating a configuration of a control system of the weighing machine 12. As shown in FIG. 6, the control circuit 60 includes a card reader 14a of the card reader box 14 and the bubble sensor 27.

When data stored in the prepaid card is input from the card reader box 14 to the memory of the control circuit 60, if the data corresponds to the capacity of the plurality of plastic containers 32, Systems 24, 26
A refueling permission setting program (refueling permission setting means) for giving refueling permission is stored. In the memory of the control circuit 60, a control program for selectively permitting refueling to the refueling system on which the plastic container 32 is mounted among the refueling systems 24 and 26 based on the detection results by the detection sensors 49A and 49B. Is stored.

Therefore, in the refueling device 11, when the data stored in the prepaid card corresponds to the capacity of the plurality of plastic containers 32, the refueling system 24, 26 is given a refueling permission and the two refueling systems 24, Since refueling can be performed simultaneously at 26, the time from the start of refueling to the plurality of plastic containers 32 to the end of refueling can be reduced. Here, an operation procedure of the self-service refueling system configured as described above will be described. First, a customer who purchases kerosene receives the reception 16 shown in FIG.
To purchase a prepaid card with a desired refueling amount at the ticket vending machine 20. Next, the customer moves to the refueling area, inserts the prepaid card into the card reader section 14a of the card reader box 14, and causes the card data (refueling data) to be read.

The POS terminal 18 waits for the metering machine 12 to output a refueling permission request signal. Then, the customer places the plastic container 32 on the tank mounting table 30.
And remove the cap of the filler port 32a of the plastic container 32. Then, grip the handle 29 of the refueling pipe mechanism 28,
The pipe 28a is slid downward to be inserted into the oil supply port 32a. Subsequently, the customer presses the fuel supply operation switch button 36 provided on the weighing machine 12 to turn it on. Then, the control circuit 60 of the weighing machine 12 sends a refueling permission signal to the POS terminal 18, and notifies the monitoring person by the display and the buzzer of the POS terminal 18. Thereby, the observer confirms safety and presses the permission button of the operation switch button 18c.

With this operation, the POS terminal 18 and the weighing machine 1
When the refueling permission signal is output to 2, the motor 48 of the refueling pump 44 is driven and the electromagnetic valve 46 is opened. Thereby, refueling of the plastic container 32 is started. While the refueling operation switch button 36 is being pressed,
Refueling of the plastic container 32 is continued. Then, when the pressing operation of the refueling operation switch button 36 is released, or when the foam sensor 27 provided in the refueling pipe mechanism 28 detects bubbles generated on the liquid surface during refueling, the electromagnetic valve 46 is closed.

When the forcible end switch button 38 is turned on, the solenoid valve 46 is closed even if the pressing operation of the refueling operation switch button 36 is released during refueling, and the refueling pump 4
4 is stopped. Thereafter, the customer grips the handle 29 of the refueling pipe mechanism 28 and slides the pipe 28a upward to refill the refueling port 32a.
Pull out from. Then, a cap is attached to the filler port 32 a of the plastic container 32, and the plastic container 32 is moved from the tank mounting table 30. If the unpaid amount remains on the prepaid card, the prepaid card is inserted into the card reader box 1
When the remaining amount of the prepaid card is zero, the prepaid card is collected in the card reader box 14.

FIGS. 7 to 10 show the control circuit 6 of the weighing machine 12.
10 is a flowchart for explaining a control process executed by the control unit 0. As shown in FIG. 7, in step S11 (hereinafter, “step” is omitted), the control circuit 60
Initialize and set each variable to zero.
In the next step S12, the refuelable capacity (designated amount) of the plastic container 32 supplied by the input device 50 is input. Subsequently, in S13, it is confirmed that the refueling operation switch button 36 has been pressed.

In S13, the refueling operation switch button 36
Is turned on, the process proceeds to S14, where the POS terminal 1
It is confirmed whether the refueling permission signal from 8 has been supplied.
In S14, when the refueling permission signal is supplied from the POS terminal 18, the process proceeds to S15, and the designated amount corresponding to the data stored in the prepaid card read by the card reader box 14 is set to the end value A.

In the next step S16, it is checked whether or not the container detection sensor 49A disposed on the left side of the weighing machine 12 has detected the plastic container 32 placed on the tank table 30. If the container detection sensor 49A does not detect the plastic container 32 in S16, the process proceeds to S17, and the weighing machine 1
It is checked whether or not the container detection sensor 49B arranged on the right side of 2 has detected the plastic container 32 placed on the tank table 30.

Then, the container detection sensors 49A and 49B
Until either or both detect the plastic container 32.
16. The processing of S17 is repeated. However, the above S
In 16, when the container detection sensor 49 </ b> A detects the plastic container 32, the process proceeds to S <b> 18, and the container detection sensor 49 </ b> B disposed on the right side of the weighing machine 12 detects the plastic container 32 mounted on the tank mounting table 30. Check whether or not.

Then, the container detection sensors 49A and 49B
When both detect the plastic container 32, since the plastic container 32 is placed at the predetermined positions on both sides of the weighing machine 12,
In S19, a value obtained by doubling the capacity Y (for example, 18 liters or 20 liters) of the plastic container 32 is set as the target value B. When the container detection sensor 49B disposed on the right side of the weighing machine 12 does not detect the plastic container 32 in S18, the process proceeds to S20, and the capacity Y of the plastic container 32 is set to the target value B.

As described above, the container detection sensors 49A and 49A
9B based on the detection result of the plastic container 32 based on the target value B
Therefore, it is possible to confirm that the plastic container 32 is mounted on the tank mounting table 30 and to set the refueling systems 24 and 26 in a refuelable state. Therefore, the poly container 32
When only one is installed, one refueling system 24
The oil supply permission is given to or 26, so that it is possible to prevent the liquid from being sent to the oil supply system where the plastic container 32 is not mounted.

Further, since the target value B is set based on the capacity Y of the plastic container 32, even when the foam sensors 27A and 27B fail, it is possible to prevent an overflow when refueling the plastic container 32. As shown in FIG. 8, in S21,
It is checked whether the forced end switch button 38 has been turned on. If the forced end switch button 38 is turned on in S21, the process proceeds to S22 and P
An end signal is transmitted to the OS terminal 18. Thus, a series of processes of this time is completed.

If it is determined in step S21 that the forced termination switch button 38 is off, the process proceeds to step S23, and the weighing machine 12
It is checked whether or not the container detection sensor 49A arranged on the left side of the above has detected the plastic container 32 placed on the tank mounting table 30. In this S23, the container detection sensor 4
When 9A detects the plastic container 32, the process proceeds to S24,
It is checked whether the foam sensor 27A provided in the refueling pipe mechanism 28 has detected foam generated on the liquid surface during refueling.

When the container detection sensor 49A is off and the plastic container 32 is not mounted on the tank mounting table 30, or when the foam sensor 27A is on and the plastic container 32 is full, refueling is performed in S25. Pump O of system 24
The N flag C is set to "0". When the container detection sensor 49A is on and the foam sensor 27A is off, the plastic container 32 mounted on the tank mounting table 30 is empty, and the pump ON flag C of the refueling system 24 is set to "1" in S26. Set to.

In S27, it is checked whether or not the container detection sensor 49B disposed on the right side of the weighing machine 12 has detected the plastic container 32 mounted on the tank mounting table 30. In this S27, when the container detection sensor 49B detects the plastic container 32, the process proceeds to S28, and it is checked whether the foam sensor 27B provided in the refueling pipe mechanism 28 has detected foam generated on the liquid surface during refueling. I do.

If the container detection sensor 49B is off and the plastic container 32 is not placed on the tank mounting table 30, or if the foam sensor 27B is on and the plastic container 32 is full, refueling is performed in S29. Pump O of system 24
The N flag C is set to "0". Further, when the container detection sensor 49B is on and the foam sensor 27B is off, the plastic container 32 placed on the tank table 30 is empty, and the pump ON flag C of the refueling system 24 is set to “1” in S30. Set to.

In the next S31, the simultaneous pump ON flag E
Is set according to the values of the pump ON flags C and D.
That is, the simultaneous pump ON flag E is determined by E = C × D. For example, the values of the pump ON flags C and D are both “1”.
, E = 1, and when one or both of C and D is “0”, E = 0. In the next S32, it is checked whether the pump ON flag C or D is set to "1". If the pump ON flag C or D is set to "1" in S32, the process proceeds to S33, where it is checked whether the refueling operation switch button 36 is turned on.

When the pump ON flag C or D is set to "0" in S32, the plastic container 32 is not mounted on the tank mounting table 30, or the plastic container 32 has been refueled. Therefore, the process proceeds to S34, in which the refueling pump 44 is stopped. When the refueling operation switch button 36 is off in S33, the operator has stopped refueling for some reason.
Then, the fuel supply pump 44 is stopped. Then, S21
And the processing after S21 is executed again.

Then, in S32, the pump ON flag C or D is set to "1", and in S33,
When the refueling operation switch button 36 is on, the plastic container 32
Since the refueling is possible, the process proceeds to S35 shown in FIG. 9 and the pump motor 48 is started. In the next S36, it is checked whether or not the simultaneous pump ON flag E is "1". If the simultaneous pump ON flag E is set to "0" in S31 described above, the flow rate of oil supplied to one plastic container 32 is large.
The switching timing flow rate F is set to “0.4 liter”. When the simultaneous pump ON flag E is set to "1", the flow rate of the simultaneous refueling to the two plastic containers 32 is small, so the process proceeds to S38, and the switching timing flow rate F is set to "0.2 liter". Set to.

[0047] The switching timing flow F, when oil is supplied to one of the plastic container 32, since the instantaneous flow rate (flow velocity) is large, the main solenoid valve 46A ₁ in 0.4 liters before the cumulative flow rate reaches the target flow rate or flow rate is throttled by switching from 46B ₁ to the sub-solenoid valve 46A ₂ or 46B _2. Further, when the two plastic containers 32 are simultaneously refueled, since the instantaneous flow rate (flow velocity) is small, the main solenoid valve 46A is turned off 0.2 liters before the integrated flow rate reaches the target flow rate.
_1, the 46B ₁ flow rate is throttled by switching the sub-solenoid valve 46A _2, 46B _2, and to reduce the overshoot when reaching the target flow rate.

In the next step S39, it is determined whether or not the current refueling amount (integrated flow rate) has exceeded the switching value. for that reason,
The switching timing flow rate F is subtracted from the end value A, and it is checked whether the current refueling amount is larger than the value. S
If the current refueling amount (integrated flow rate) has not reached the switching value in S39, the process proceeds to S40, in which the switching timing flow rate F is subtracted from the target value B, and it is determined whether the current refueling amount is greater than the value. To check.

In S39, when the current refueling amount (integrated flow rate) has reached the switching value, or in S40, the current refueling amount has reached a value obtained by subtracting the switching timing flow rate F from the target value B. Sometimes, S41 to S46
Is executed. However, when the current refueling amount (integrated flow rate) has not reached the switching value in S39, and when the current refueling amount has not reached the value obtained by subtracting the switching timing flow rate F from the target value B in S40, The main solenoid valve processing of S47 to S52 is executed.

That is, refueling of the plastic container 32 is started.
Initially, the refueling amount (integrated flow rate) is still small, so S4
7 and whether the simultaneous pump ON flag E is "1"
Check. In this S47, simultaneous pump ON
When the flag E is set to "1", the process proceeds to S50.
Advance and main solenoid valves 46A on the 1 and 2 sides₁, 46B ₁
Is opened.

If the simultaneous pump ON flag E is set to "0" in S47, the flow advances to S48 to check whether the pump ON flag C is "1". In this S48, the pump ON flag C is set to "1".
When set, the process proceeds to S51, thereby opening one side of the main solenoid valve 46A _1. Then, if the pump ON flag C is set to "0" in S48, the process proceeds to S49, and it is checked whether the pump ON flag D is "1". In this S49, the pump is turned on.
If the flag D is set to "1", the flow proceeds to S52, to open the main solenoid valve 46A ₂ of 2 side.

Further, when the refueling of the plastic container 32 is performed and the refueling amount (integrated flow rate) increases, the above-described S39 is performed.
In, when the current refueling amount (integrated flow rate) has reached the switching value, or in S40, when the current refueling amount has reached the value obtained by subtracting the switching timing flow rate F from the target value B, the process proceeds to S41. It is checked whether the simultaneous pump ON flag E is "1". In this S41,
When the simultaneous pump ON flag E is set to "1", the process proceeds to S44, where the main solenoid valves 46 on the first and second sides are set.
Together to close the A _1, 46B _1, sub-solenoid valve 46A
_2, 46B ₂ to open the. Thereby, the plastic container 32
The amount of refueling is reduced, the excess amount when the tank is full is reduced, and the refueling accuracy is improved.

If the simultaneous pump ON flag E is set to "0" in S42, the process proceeds to S43, where it is checked whether the pump ON flag C is "1". In this S42, the pump ON flag C is set to "1".
When set, the process proceeds to S51, together to close the main solenoid valve 46A ₁ of 1 side, the sub-solenoid valve 46
To open the A _1.

If the pump ON flag C is set to "0" in S42, the flow advances to S43 to check whether the pump ON flag D is "1". In this S43, the pump ON flag D is set to "1".
When set, the process proceeds to S46, the 2 side of the main solenoid valve 46A ₂ causes closed, the sub-solenoid valve 46
To open the A _2.

Next, at S53 shown in FIG. 10, the refueling amount (integrated flow rate) is the end value A set by the input device 50.
Check if you have reached In this S53, when the refueling amount (integrated flow rate) reaches the end value A,
Since the preset refuelable amount has been reached, the process proceeds to S54, and the refueling pump 44 is stopped. Then, the process returns to S22 described above, and transmits an end signal to the POS terminal 18. Thus, a series of processes of this time is completed.

When the refueling amount (integrated flow rate) has not reached the end value A in S53, the process proceeds to S55,
It is checked whether the refueling amount has reached the target value B (integrated flow rate). In S55, the refueling amount (integrated flow rate)
If does not reach the target value B, the process returns to S21 (see FIG. 8) described above, and the processing after S21 for confirming the state of the forced termination switch button 38 is executed.

At S55, the refueling amount (integrated flow rate)
Has reached the target value B, the routine proceeds to S54, where the refueling pump 44 is temporarily stopped. Then, the process returns to S22 described above, and transmits an end signal to the POS terminal 18. with this,
This series of processing ends. As described above, when the data stored in the prepaid card read by the card reader box 14 is a refueling amount or a refueling amount that can refuel the plurality of plastic containers 32, the two refueling systems 24, 2
6, it is possible to refuel at the same time, so that the refueling time for all the poly containers 32 can be shortened and the refueling efficiency can be improved.

Thus, when there are a number of customers performing self-service refueling, the refueling time of each customer can be shortened, and the waiting time of the customer behind the line can be shortened. In the above embodiment, the case where kerosene is sold has been described as an example. However, the present invention is not limited to this, and it goes without saying that the present invention can be applied to a case where an oil liquid other than kerosene is supplied to a plastic container for sale.

[0059]

As described above, according to the first aspect of the present invention, when refueling amount data corresponding to a plurality of refueling tanks is input from the input means, a refueling permission is given to a plurality of refueling systems. When there are multiple refueling tanks to be refueled, it is possible to refuel at the same time in multiple refueling systems,
The time from the start of refueling to the end of refueling of all refueling tanks can be shortened, and the refueling efficiency can be increased. Therefore, when there are a number of customers performing self-service refueling, the refueling time of each customer can be shortened, and the waiting time of the customer behind the queue can be shortened.

According to the second aspect of the present invention, a refueling permission is selectively given to the refueling system on which the refueling tank is mounted among a plurality of refueling systems based on the detection result by the detecting means. It is possible to prevent liquid supply to a refueling system where no lubricated tank is mounted, and to simultaneously lubricate a plurality of lubricated tanks to be refueled by mounting them at predetermined positions in a plurality of lubrication systems. Refueling time to the refueling tank can be reduced.
