[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lubricating apparatus, and more particularly to a method for judging an oil type of an underground tank connected to a pipe in an oiling apparatus and automatically setting the judged oil type as an oil type of an oil supply nozzle. The present invention relates to a refueling device having a self-learning function.

[0002]

2. Description of the Related Art Conventionally, when installing a refueling device in a gas station, a suction pipe communicating with an underground tank buried under the gas station and opening and opening on an island, and a lubricating pump for the oil pump inside the oil device are conventionally used. The connection work with the piping on the liquid pumping side is performed. When the connection work between the suction pipe of the underground tank and the pipe of the oil supply device is completed, the oil type (oil supply nozzle supply oil type) of the underground tank to which the suction pipe communicates is set and registered in advance from the setting unit of the oil supply device. It has become. Thus, for example, in a refueling device having an oil type determination function, when the refueling nozzle is inserted into the fuel tank when refueling a vehicle or the like, the refueling device operates based on the concentration of the oil vapor sucked from the fuel tank. The oil type is detected, and only when the oil type in the fuel tank matches the oil type supplied from the oil supply nozzle described above, the oil supply pump is driven to start pumping oil from the underground tank, and the oil supply nozzle is started. The refueling is enabled.

However, the above prior art has the following problems. That is, after connecting the piping of the oil supply device and the suction pipe of the underground tank at the time of the installation work of the oil supply device, the oil type (oil supply nozzle supply oil type) of the underground tank to which the suction pipe connected from the setting portion of the oil supply device communicates. )
It is necessary to perform the setting operation of the oil type setting work while confirming the connection relationship between the suction pipe and the underground tank with the piping diagram. There is a problem in that when the underground tank that communicates is misunderstood or the like, the oil type may be incorrectly set. That is, if the oil type of the refueling nozzle is erroneously set to gasoline from the setting unit of the refueling device even though the oil type of the underground tank is light oil, the fuel type is determined at the time of determining the oil type before the refueling of the gasoline vehicle starts. As a result of the match between the tank oil type and the oil type set in the oil supply device, the oil supply pump is driven and becomes ready for oil supply.However, since the oil type actually pumped from the underground tank is light oil, erroneous oiling occurs. There was a problem that could be.

[0004] The present invention solves the above-mentioned problems, and self-learning for judging an oil type of an underground tank connected to a pipe inside an oil supply device and automatically setting the judged oil type as an oil supply type of an oil supply nozzle. It is an object of the present invention to provide a refueling device which has a function and simplifies setting of an oil type when a refueling device is installed in a gas station and prevents erroneous refueling.

[0005]

According to the present invention, there is provided an oil supply nozzle, liquid supply means for supplying an oil liquid in an oil liquid storage tank to the oil supply nozzle, and an oil supply target tank for supplying the oil liquid by the oil supply nozzle. Oil vapor detecting means for detecting the oil vapor of the fuel tank, and an oil type supplied from the oil nozzle in advance are set and stored, and the oil type of the tank to be refueled is determined based on the output of the oil vapor detecting means. Determining means for determining whether or not the set oil type matches the oil type. If the oil type of the tank to be refueled matches the set oil type by the determination means, the oil liquid storage tank is supplied to the oil supply nozzle. A liquid supply control means for permitting driving of the liquid supply means for supplying the liquid oil, the setting for detecting oil vapor generated from the oil liquid in the oil liquid storage tank. Oil vapor detecting means; Instruction means for instructing the setting of the type of oil supplied from the nozzle, and identification means for identifying the oil type based on the output of the oil vapor detecting means for setting when the instruction of setting the type of oil supply is instructed by the instruction means. Registering means for setting and registering the oil type identified by the identification means as the oil type supplied from the oil supply nozzle in the determination means. Further, the oil vapor detecting means for oil supply and the oil vapor detecting means for setting of the present invention are characterized in that they are configured to be shared by a single oil vapor detecting means.

[0006]

According to the present invention, when the instruction means is operated to instruct the setting of the oil supply type of the oil supply nozzle, the identification means identifies the oil type from the output of the setting oil vapor detection means. Then, the registration means sets and registers the identification oil type as the oil supply type of the oil supply nozzle. Thus, the trouble of performing the oil type setting operation by the setting unit of the oil supply device as in the related art can be eliminated, and the accurate oil type setting can be performed.

When installing a refueling device at a gas station,
After the connection work between the lubrication system piping and the underground tank suction pipe is completed, reset the lubrication system to the refueling mode (with the oil type determination function released and the lubrication nozzle removed from the nozzle housing only). In this mode, the pump motor is driven to enable refueling, and after the oil liquid pumped from the underground tank is once supplied to the detection reference tank for oil type determination prepared in advance, the self-learning function By setting the mode, the oil type supplied to the detection reference tank is identified, and the identified underground tank oil type is set as the oil type set for the oil supply device. As a result, it is possible to eliminate the complexity of setting and inputting the oil type of the oil supply device from the setting unit at the time of installation work of the oil supply device as in the related art. The refueling devices of the second, third, and fourth embodiments described later also have a self-learning function similar to that of the first embodiment.

The oil supply device according to the first embodiment includes a pipe 1 connected from an underground tank (not shown) to a suction pipe (not shown), and a pump unit 2 for pumping oil through the pipe 1. A pump unit 4 having an air separator unit 3 for separating a liquid,
A pump motor 5 for driving the pump section 2;
A relief pipe 6 provided between the air separator section 3 and the air separator section 3, a flow meter 7 for measuring a flow rate, a flow rate pulse transmitter 8 for outputting a pulse proportional to the flow rate, and a downstream side of the pipe 1.

1. A setting switch 22 for setting the refueling device to a self-learning mode (a mode in which the oil type of the underground tank is identified and the discriminated oil type is set to the oil type of the refueling device). A self-learning setting operation unit 24 including a reset switch 23 for driving the pump motor 5 to enable refueling only on condition that the refueling nozzle 10 is removed from the nozzle storage unit 11; Flag (set state: oil type determination function is released, oil supply nozzle 10 is reset, and oil supply is possible only on condition that oil supply nozzle 10 is removed from nozzle storage section 11. Reset state: oil type determination function is activated. And a control unit 25 for controlling each part of the refueling device, which incorporates a normal refueling state in which refueling can be performed when the fuel tank oil type matches the set oil type.

Next, a control configuration of each part of the first embodiment having the above configuration will be described with reference to FIGS. First, in the refueling process shown in FIG. 2, when the worker removes the refueling nozzle 10 of the refueling device from the nozzle housing portion 11 to start refueling the fuel tank of the vehicle or the like, the nozzle switch 12 is turned on (step SA1). ), The control unit 25 determines the state of the reset flag (step SA2). When the reset flag is in the set state (state in which the oil type determination function is canceled and refueling is performed), the control unit 25 proceeds to step SA6 described below, drives the pump motor 5 and causes the pump unit 2 to perform the operation from the underground tank. While the pumping of the oil liquid is started to make it possible to supply oil, if the reset flag is in a reset state (a state in which the oil type determination function is operated to supply oil), the suction / discharge unit 19 is driven to intake air (step SA3). Accordingly, when the worker inserts the fueling nozzle 10 into the vehicle fuel tank, the oil vapor in the fuel tank is sucked toward the oil vapor sensor 15 through the intake hose 13 and the intake pipe 14, so that the control unit 25 It is determined whether the oil type of the fuel tank matches the oil type set in the oil supply device based on the detection result by the oil vapor sensor 15 (step SA4). If the control unit 25 determines that the fuel tank oil type matches the set oil type, the control unit 25 stops the intake drive of the suction / discharge unit 19 (step SA5), drives the pump motor 5, and causes the pump unit 2 to operate the pump unit 2 from the underground tank. The pumping of the oil liquid is started to make it possible to supply oil (step SA6). As the worker refuels the vehicle or the like, the control unit 25 performs measurement and calculation of the refueling amount based on the flow rate pulse output from the flow rate pulse transmitter 8 (step SA7). On the other hand, if the control unit 25 determines in step SA4 that the fuel tank oil type does not match the set oil type, the pump motor 5 is not driven, and thereafter, the operator stores the refueling nozzle 10 in the nozzle housing. Part 1
When the nozzle switch 12 is turned off by returning to step 1 (step SA8), step SA1 described later is performed.
2, and the suction / discharge unit 19 is driven to exhaust for a predetermined time.
The cleaning of the oil vapor sensor 15 and the suction hose 13 is performed.

Next, the control unit 25 determines whether the nozzle switch 12 is ON or OFF, that is, whether or not the worker has returned the refueling nozzle 10 to the nozzle storage unit 11 upon completion of the refueling operation (step SA9). When the oil supply nozzle 10 is returned to the nozzle housing 11, the drive of the pump motor 5 is stopped, and the pumping of the oil liquid from the underground tank by the pump 2 is stopped (step SA10). Next, the control unit 25 determines the state of the reset flag (step SA11). If the reset flag is in the reset state (a state in which the oil type determination function is activated to supply oil), the intake drive of the suction / discharge unit 19 is performed. After stopping, the pump is driven to exhaust for a predetermined time.
5 and the intake hose 13 are cleaned (step SA12). As a result, the residual oil vapor in the intake hose 13, the intake pipe 14, and the oil vapor sensor 15 is exhausted to the outside of the oil supply device, so that both are cleaned. On the other hand, in step SA11, when the reset flag is in the set state (the state in which the oil type determination function is canceled and refueling is performed), the control unit 25 resets the reset flag in preparation for the next refueling (step SA13). ). Thereafter, the control unit 25 checks whether or not the oil vapor sensor 15 has returned to a state in which oil vapor can be detected at the time of the next refueling by the above cleaning (step SA14), and if not, returns to the step SA12. Suction and discharge unit 1
While the exhaust driving of No. 9 is performed for a predetermined period of time, if the operation has returned, the above series of processing ends. The reset switch 23 is normally used, for example, when refueling a single vehicle with a shallow fuel tank, in addition to the oil type determination described below.

FIG. 3 shows a reset process performed at the time of determining the oil type in the refueling device.
The operator resets the refueling device to a refueling mode (a mode in which the oil type determination function is released and oil refueling can be performed when the refueling nozzle 10 is removed from the nozzle housing 11) or a normal refueling mode (operates the oil type determination function). When the reset switch 23 is operated in a state where the fuel tank oil type and the set oil type match each other, the control unit 25 reads the operation of the reset switch 23 (step SB1). Next, the control unit 25 determines whether the reset flag is already set or already reset, that is, whether the reset refueling mode is already set or the normal refueling mode is already set (step S).
B2) On the other hand, when it is determined that the reset flag has already been reset, the set state is set for the next time (step SB3). When it is determined that the reset flag is already set, the reset state is set for the next time. (Step SB4).

First, the operator operates the reset switch 23 of the self-learning setting operation section 24 when the refueling device is set to the self-learning mode, and the oil liquid pumped from the underground tank is supplied to the underground tank oil prepared in advance. After once refueling the detection reference tank for species determination, the refueling device is set to a self-learning mode to identify the type of oil refueled to the detection reference tank and to use the identified underground tank oil type for the set oil of the refueling device. Seeds. That is, in the self-learning mode process of FIGS. 4 and 5, the worker sets the oil supply device in the self-learning mode (identifies the oil type of the underground tank that supplies the oil liquid to the oil supply device, and sets the identified oil type to the oil supply device. When the setting switch 22 of the self-learning setting operation section 24 is operated in order to set the oil type),
The control unit 25 reads the operation state of the setting switch 22 (step SC1). When the operator removes the oil supply nozzle 10 from the nozzle housing 11 to supply the detected oil liquid in the underground tank to the detection reference tank (the tank for determining the oil type in the underground tank), the nozzle switch 12 is turned on (step S).
C2) The control unit 25 starts time measurement by the built-in intake timer (step SC3), and drives the intake / discharge unit 19 to intake (step SC4). Accordingly, the oil vapor in the detection reference tank to which the detection oil liquid has been supplied from the underground tank is sucked toward the oil vapor sensor 15 via the intake hose 13 and the intake pipe 14, so that the control unit 25 It is determined whether or not the detection level of the oil vapor sensor 15 exceeds the gasoline level (threshold for determining whether the oil type is gasoline). Also, at this time, "under oil type determination" is displayed on the setting display 21 of the self-learning setting operation section 24 of the refueling device (step SC5). And control unit 2
When it is determined that the detection level of the oil vapor sensor 15 exceeds the gasoline level, the intake drive of the intake / exhaust unit 19 is stopped (step SC6), and the timing of the intake time by the intake timer is stopped. Is reset (step SC7), and the set oil type (oil type of the underground tank) of the oil supply device is set to “gasoline”. Also, at this time,
The setting indicator 21 displays the setting oil type 'gasoline' (step SC8). After that, the processing shifts to the processing of step SC15 and subsequent steps.

On the other hand, if the control unit 25 determines in step SC5 that the detection level of the oil vapor sensor 15 is lower than the gasoline level, the time measured by the built-in oil type determination timer reaches a preset oil type determination time. It is determined whether the oil type determination time has been reached (step SC9). If the oil type determination time has not been reached, the process returns to step SC5, where the detection level of the oil vapor sensor 15 is compared with the gasoline level, while the oil type determination time has been reached. In this case, the suction drive of the suction / discharge unit 19 is stopped (step SC10), and the counting of the suction time by the suction timer is stopped and the counting is reset (step SC11). Next, the control unit 25 determines whether or not the detection level of the oil vapor sensor 15 is equal to or higher than the light oil level (threshold for determining whether the oil type is light oil) and lower than the gasoline level (step SC12). When the detection level of the oil vapor sensor 15 is equal to or higher than the light oil level and lower than the gasoline level, the control unit 25 sets the oil type (oil type in the underground tank) of the oil supply device to “light oil” (step SC13), while the oil vapor is set. If the detection level of the sensor 15 is not within the above range, a guidance indicating that "the set oil type cannot be determined" is displayed on the setting display 21 of the self-learning setting operation unit 24 (step SC1).
4). After that, the processing shifts to the processing of step SC15 and subsequent steps.

Thereafter, the control unit 25 starts time counting by a built-in exhaust timer (step SC15), and drives the exhaust unit 19 to exhaust (step SC16). Thereby, residual oil vapor in the intake hose 13, the intake pipe 14, and the oil vapor sensor 15 is exhausted to the outside of the oil supply device. Next, the control unit 25 determines whether the nozzle switch 12 is ON or OFF (whether the operator has removed the fueling nozzle 10 from the nozzle storage unit 11 or has returned it) (step SC1).
7) When the nozzle switch 12 is turned off (when the operator returns the refueling nozzle 10 to the nozzle storage section 11)
Determines whether the time measured by the exhaust timer has passed a predetermined time required for cleaning the residual oil vapor set in advance (step SC18). If the predetermined time has elapsed, the exhaust drive of the suction / discharge unit 19 is performed. The timer is stopped (step SC19), the measurement of the exhaust time by the exhaust timer is stopped, and the timer is reset (step SC2).
0). On the other hand, the control unit 25 determines whether the nozzle switch 12 is ON or OFF if the time measured by the exhaust timer has not elapsed in step SC18 (step SC21).
On the other hand, if it is OFF, the above step SC1
It returns to the judgment of 8. After the end of step SC20, the control unit 25 determines whether or not the detection level of the oil vapor sensor 15 is lower than the light oil level (step SC22). If it is less than the above, the above series of processing ends. That is, according to the first embodiment, at the time of the installation work for connecting the piping of the oil supply device to the suction pipe communicating with the underground tank as in the related art, the oil type is incorrectly set by misunderstanding the underground tank to be connected. The oil type that the pump actually pumps from the underground tank is different from the oil type set for the oil nozzle due to the incorrect setting of the oil type for the oil nozzle from the setting section of the oil supply device. Therefore, problems such as erroneous refueling can be solved.
