Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a liquid supply device for supplying different types of oil to each hatch of a lorry in, for example, an oil depot.

[Prior art] At an oil depot, a lorry driver looks at a refueling slip with refueling data printed on it, refuels each hatch of the lorry with various types of oil, such as regular gasoline, high-octane gasoline, kerosene, etc., and then takes this to the gas station. The oil from each hatch is unloaded into underground tanks.

It is fine if the lorry driver refuels each hatch with the same oil as shown on the refueling slip without making any mistakes at the oil depot, but if he refuels with the wrong type of oil, he may unload the wrong oil into the underground tank at the refueling station. I will do it.
The oil mixed in this way was not only dangerous but also unusable, resulting in a large loss.

For example, Japanese Patent Application Laid-Open No. 59-93698 discloses a device for preventing liquids discharged from a tank having a plurality of chambers from being mixed up. however,
In such known technology, when fuel is incorrectly refueled, the lamp on the display only lights up, and the refueling operation can be performed at will. Therefore, there is a risk of incorrect oil supply, and since the control valve is operated manually, a small amount of mixed oil may occur, for example, when looking at the display for confirmation after opening the valve.

[Object of the Invention] Accordingly, an object of the present invention is to provide a liquid supply device that cannot supply oil other than the same type of oil and does not cause mixed oil.

[Structure of the Invention] According to the present invention, a detection device provided for each hatch of the lorry, and a detection device provided on the loading arm of each liquid supply system consisting of a flow meter, a control valve, and a oil supply system control means. In a liquid supply device equipped with a container,
A liquid supply data storage means that stores liquid supply data of the type of liquid to be loaded for each lorry hatch, and a detector that is output when the hatch and liquid type stored in the liquid supply data storage means are connected to the device to be detected. determining means for comparing hatch and liquid type signals obtained from signals from the above; and liquid supply permission means for outputting a liquid supply permission signal to the oil supply system control means when the signals match; and liquid supply permission means for outputting a liquid supply permission signal to the oil supply system control means when the signals do not match. If the signals match according to the judgment means, refueling is possible, and if they do not match, refueling is not permitted and a notification is given.

[Operations and Effects of the Invention] Therefore, when supplying liquid, the device to be detected is connected to the detector, and the liquid supply permission signal is output to the control valve only when the signal from the detector is the same as the liquid supply data. If they are different, the liquid supply permission signal is not output to the control valve, so each hatch is always supplied with the same type of liquid as in the liquid supply slip. Therefore, there is no need to unload different liquids, and there is no risk of mixing liquids.

Since the control valve will not open unless permission is given to supply liquid, there will be no mixing of liquids. Therefore, the operator can easily notice the mistake, and the efficiency of the liquid supply operation is improved.

[Preferred Embodiment] When the present invention is implemented, for example, in an oil depot, the detector is installed on the loading arm, and the device to be detected is installed near the hatch opening, so that the connection work with the device to be detected is easy. There are also no erroneous operations.

Control devices, or computers, are installed at various locations in oil depots, such as in offices and on racks, and these control devices are connected to each other through serial transmission. Therefore, each means of the control device for preventing erroneous refueling can be incorporated into a control device installed in an office or a rack. Moreover, these means can also be provided separately.

[Examples] Examples of the present invention will be described below with reference to the drawings.

FIG. 1 shows an oil depot in which the present invention is implemented. In the figure, a rack, which is designated as a whole by reference numeral 1, has a plurality of (three in the illustrated embodiment) oil supply systems 2a, 2.
b and 2c, and a local computer that controls the oil supply systems 2a to 2c.
The RC and display sections 3a to 3c connected thereto are provided at easy-to-see positions above the rack 1.
The refueling system 2a supplies high octane gasoline, the refueling system 2b supplies regular gasoline, and the refueling system 2c supplies kerosene.

Each loading arm 6 is provided with a start switch SW connected to a local computer RC and a detector 20. In the figure, numeral 12 is a flow meter, and 13 is a control valve. As is well known, the tank 7 of the lorry 5 is divided into a plurality of hatches 8a to 8d.
A detection device 30 is attached via a string 33 to the vicinity of the hatch opening into which the loading arm 6 is inserted, and these detectors 20 and detection device 30 constitute a hatch identification device. (In the drawing, the detected tool 30b of the hatch 8b is the detector 2 of the oil supply system 2b.
It is shown connected to 0b. )
A card reader 11 for checking the vehicle number of the lorry 5 and a control device (local computer) RC for preventing incorrect refueling having operation buttons are installed at appropriate locations in the rack 1, and a ground connector 10
and card reader 11 are connected to local computer RC.

On the other hand, in office O, which is far from Rack 1, there is a control device (host computer) that manages the entire oil depot.
HC is provided and local computer RC
is connected to the host computer HC via line L. The host computer HC has a display 14, an input button 15, a printer 16, an external storage device F, and the like.

Next, the operation will be explained.

Host computer HC installed in office O
The refueling data entered through the keyboard 15 is totaled and stored, and the printer 16 issues a refueling slip 31 on which the refueling data shown in FIG. 4 is printed. This slip 31 includes the vehicle number of the lorry, and the type and amount of oil for each hatch. Lori 5 came to the oil depot
receives the refueling slip 31 at Office O, stops at the Rack 1 refueling area, and connects the earth connector 10.
When the card for Loli 5 is read by the card reader 11, the card data transmission means 21 of the local computer RC provided on the rack 1 outputs a ground signal connected to the ground 10 (step S1).
The host then receives a card reading signal from the card reader 11 (step S2) and outputs a card data signal such as the car number written on the card to the host computer HC via the transmitting/receiving means 34 (step S3). The computer HC receives this signal and outputs refueling data for the vehicle number. The local computer RC receives the refueling data (step S4) and stores it in the storage means 22 (step S4).
S5).

Next, the operator inserts the loading arm 6 into the hatch 8 by looking at the refueling slip, and connects the detection target 30 to the detector 20. Loading arm oil type signal is sent to local computer RC
(step S6) and is compared with the refueling data stored in the storage means 22 by the determination means 23.
Determine whether the loading arm of the correct oil type is pressed into the correct hatch (step
S7). If it is not correct, a notification signal is issued (step S8) and the notification device 35 is activated. If correct,
The refueling permission means 24 issues a refueling permission signal to the refueling system control means 32 (step S9).

The corresponding refueling system receives this refueling permission signal and becomes ready for refueling. Next, start switch
When SW is pressed, the control valve 13 is opened by the action of the oil supply system control means 32, oil is supplied, and the flow meter 12
The flow rate signal from is displayed on the display unit 3, and when the amount of oil stored in the storage means 22 is filled,
The control valve 13 is closed, and this oil supply system ends the oil supply (step S11). The refueling completion determining means 36 determines whether refueling for all refueling data has been completed (step S12), and if not, it waits for the next refueling to end. The operator refuels another hatch using the same operation as described above. When refueling for all refueling data has been completed (step S12), the refueling completion determination means 36 outputs a refueling completion signal to the host computer HC (step S13). Upon receiving this refueling completion signal, the host computer The refueling data of the vehicle number is classified and stored in the external storage device F, and all refueling processing is completed.

Note that the present invention is not limited to the above-mentioned embodiments, but can be applied to liquid supply devices for liquids such as paints and foods. Further, in the embodiment, the liquid supply device is limited by the host computer and the local computer, but it may be controlled by a single computer.

[Summary] As described above, according to the present invention, since the refueling data and the signal from the detector are compared and the refueling permission signal is output to the control valve, there is no risk of incorrect refueling.
The lorry driver can also perform appropriate refueling work without relying on memory.
