Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tank lorry having a function of judging an oil type at the time of refueling an oil storage tank installed in a gas station and preventing lubrication of a different oil type.

[0002]

2. Description of the Related Art When replenishing fuel oil from a tank truck to an oil storage tank, it is necessary to confirm that the oil type to be replenished from a hatch matches the oil type of the oil storage tank in order to prevent oil mixture. However, since the judgment is manually performed, there is a possibility that an error sometimes occurs. For this reason,
As described in Japanese Patent Publication No. 3-249380, the male coupling provided on the discharge pipe of the lorry is provided with oil type determination means, and the female coupling provided on the oil supply pipe of the oil storage tank is provided with a length depending on the oil type. There has also been proposed one having different projections and mechanically transmitting the length of the projections to oil type determination means by a wire inserted into an oiling hose.

[0003] However, since the result of oil type determination is transmitted by a wire, there is a possibility that a determination error may occur due to an error due to play or elongation of the wire, and the cross-sectional area of the flow passage is reduced by the amount of the wire to be accommodated. There is a problem that the time required for the process becomes long. In order to solve such a problem, the applicant has previously disclosed a plurality of hatches connected to a discharge pipe having a first coupling via a bottom valve, and a plurality of hatches connectable to the first coupling. In a lorry for unloading the oil storage tank by an oiling hose provided with a second coupling and a fourth coupling connectable to the third coupling of the oil storage tank, a third coupling is provided near the fourth coupling.
An identification piece reading means for reading and wirelessly reading an oil type identification piece provided in the vicinity of the coupling, receiving a signal from the identification piece reading means, receiving a read result and an oil type of a hatch number from a keyboard. And proposed a tank trolley provided with a control means for enabling the bottom valve specified by the keyboard to be opened when they match.

[0004]

According to this, the oil type of the identification piece indicating the oil type of each oil storage tank can be received by a radio signal to determine the oil type with high reliability. Although the area is not reduced and the unloading time can be shortened, it is installed on the tank lorry when the distance between the position where the lorry can be stopped and the lubrication pipe is longer than the length of one lubrication hose. Even if a plurality of lubricating hoses are connected in series and lubricated, it is impossible to lubricate over a long distance because the coupling of the hoses cannot be connected. The present invention has been made in view of such a problem, and its object is to not only determine the oil type with high reliability, but also to connect two lubricating hoses in series for a long time. An object of the present invention is to provide a tank truck that can be unloaded at a distance.

[0005]

In order to achieve the above object, according to the present invention, one end can be connected to first and second discharge pipes connected to each of a plurality of hatches via a bottom valve. First and second lubricating hoses having a first coupling, a second coupling connectable to a first coupling at the other end, and a coupling of a lubrication pipe of the oil storage tank; A hose identification piece provided near the first coupling of the first and second lubricating hoses, and a hose identification piece provided near the second coupling of the first and second lubricating hoses; An identification piece reading means for reading an oil type identification piece provided in the vicinity of an oil supply pipe of the oil storage tank and outputting the same by a radio signal; a hose sensor provided in the vicinity of the discharge pipe for reading a hose identification piece; No signal received from reading means Receiving means, a hatch number input keyboard, a signal from the hose sensor, a radio signal from the identification piece reading means, and a signal indicating the oil type from the identification piece reading means of the lubricating hose connected to the discharge pipe; If you have
Or, when a signal indicating the oil type is received from the identification piece reading means of a different lubrication hose, a signal indicating the lubrication hose from the identification piece reading means of the other lubrication hose is received, and a signal from the identification piece reading means is received. And a control means for comparing the oil type of the hatch number from the keyboard and opening the bottom valve specified by the keyboard when they match with each other.

[0006]

When the lubrication is performed by one lubrication hose, the connection to the discharge pipe is confirmed by the hose sensor, the oil type of the oil storage tank is confirmed by the identification piece reading means, and the two lubrication hoses are connected. When lubricating with oil, insert the identification piece of one oiling hose into the hose sensor, insert the identification piece of the other oiling hose into the identification piece reading means of one oiling hose, and read the identification piece of the other oiling hose. The connection with the discharge pipe, the connection of the two hoses, and the type of oil are confirmed by inserting the identification piece of the lubrication pipe into the means.

And a determination means 67 for making notification.

The storage means 65 stores hatch number data 68 and discharge pipe data 69 as fixed data as shown in FIG. 7, and rewritably stores oil type data 70 in correspondence with the hatch number. The configuration is such that oil type data 70 corresponding to the hatch number input from 61 is output to the determination means 67.

Next, the operation of the above-configured apparatus will be described with reference to the flowcharts shown in FIGS. (When unloading is performed with one lubrication hose) No. 1
When unloading is performed from the hatch 1 communicating with the discharge pipe 9 of the first discharge pipe 9, the first oiling hose X is lowered from the vehicle, and the first coupling 21 is connected to the coupling 11 of the first discharge pipe 9.
Next, the second coupling 22 is connected to the coupling 17 of the lubrication pipe 16. Then, the hose identification piece 24 is loaded on the hose sensor 13 of the discharge pipe 9, and the oil type identification piece 18 provided on the lubrication pipe 16 is loaded on the identification piece reading means 25.

Next, after a command to start unloading is issued by the keyboard 61 (step a in FIG. 8), the keyboard 6
When the hatch number “1” is input by 1 (Step B in FIG. 8), connection determination and oil type determination of the lubricating hoses X and Y are performed (Step C in FIG. 8).

That is, the controller 60 controls the hose sensor 1
3, a signal (represented as "sensor A" in the flowchart) accompanying the insertion of the hose identification piece 24 is input by the switch 52 of FIG.
5 reads the oil type of the oil storage tank 15 recorded on the oil type identification piece 18 of the oil supply pipe 16 and transmits a radio signal (represented as “Transmitter X ′” in the flowchart) from the radio transmission means 44, R inputs (Fig. 9 Step
B). Then, the determining means 67 determines that the discharge pipe 9 is connected to the oil storage tank of the oil type R (FIG.
C).

Based on the hatch number "1" input from the keyboard 61, the judging means 67 outputs the discharge pipe number "1" and the oil type "regular" stored in the storage means 65 as shown in FIG. Is read, and the state of the previously determined state, that is, the difference of the discharge pipe number and the oil type from “the discharge pipe 9 is connected to the oil storage tank of the oil type R” is determined (step C in FIG. 8). The lubrication hose X is connected to the first discharge pipe 9 and the oil type matches (FIG. 8
D) The display 61 indicates that lubrication is possible (FIG. 8).
Step e).

If the oil type of the designated hatch does not match the oil type of the oil storage tank 15, an alarm is issued by the alarm 63 (FIG. 8).

Next, when an unloading command is issued (step F in FIG. 8), the bottom valve 5 of the hatch 1 is opened (step S in FIG. 8), and the fuel oil of the oil type R is injected into the oil storage tank 15.

When the unloading is completed and an end command is issued from the keyboard 61 (FIG. 8 step), and the number "1" of the hatch 1 whose unloading has been completed is input from the keyboard 61 (FIG. 8 step), the hatch The first bottom valve 5 is closed (FIG. 8, step n).

The unloading using the second lubricating hose Y can also be performed through the same process as described above. That is, a signal associated with the insertion of the identification piece 34 is input by the switch 52 of the hose sensor 13 (step d in FIG. 9), and the identification piece reading means 35 reads the oil storage tank 15 recorded in the identification piece 18 of the lubrication pipe 16. The oil type R is read, a signal is transmitted from the wireless transmission means 44, and the oil type R is input (step E in FIG. 9). Then, the judgment means 67
Determines that the discharge pipe 9 has been connected to the oil storage tank of the oil type R (step c in FIG. 9).

Based on the hatch number "1" input from the keyboard 61, the judging means 67 outputs the discharge pipe number "1" and the oil type "regular" stored in the storage means 65 as shown in FIG. Is read, and the state of the previously determined state, that is, the difference of the discharge pipe number and the oil type from “the discharge pipe 9 is connected to the oil storage tank of the oil type R” is determined (step C in FIG. 8). Since the lubrication hose Y is connected to the first discharge pipe 9 and the oil type also matches (FIG. 8 step
D), indicating that lubrication is possible is displayed on the display 61 (step F in FIG. 8), and lubrication is performed through steps (f), (h), (h) to (nu) in FIG. Can be executed.

(When unloading by connecting two lubricating hoses X and Y) The position where the lorry 10 can stop and the lubricating pipe 16
Is longer than the lubrication hoses X and Y, the lubrication is performed by connecting the lubrication hoses X and Y.

That is, as shown in FIG. 3, the first coupling 21 of one oiling hose X is connected to the coupling 11 of the discharge pipe 9 and the second coupling 22 is connected to the first coupling 21 of the other oiling hose Y. And the second coupling 32 of the lubrication hose Y is connected to the coupling 17 of the lubrication pipe 16.

Then, the oil type identification piece 24 of the lubricating hose X
To the hose sensor 13 of the discharge pipe 9, the hose identification piece 34 of the oiling hose Y to the identification piece reading means 25 of the oiling hose X,
Further, the oil type identification piece 18 of the oil supply pipe 16 is loaded into the identification piece reading means 35 of the oil hose H. Next, after a command to start unloading is issued by the keyboard 61 (Step A in FIG. 8), when the hatch number “1” is inputted by the keyboard 61 (Step B in FIG. 8), the connection determination between the lubricating hoses X and Y is made. Alternatively, oil type determination is performed (step c in FIG. 8).

That is, the controller 60 controls the hose sensor 1
3, the signal of the hose identification piece 24 is input (Step A in FIG. 9), and the oil type data is not transmitted from the identification piece reading means 25 of the lubricating hose X (Step B in FIG. 9). The hose data of the second lubricating hose Y is transmitted (step F in FIG. 9), and the signal of the identification piece reading means 35 of the second lubricating hose Y (in the flowchart, represented as “transmitter Y ′”) is used as the oil type. R has been transmitted (step 9 in FIG. 9). Therefore, the determination means 67 determines that the discharge pipe 9 is connected to the oil storage tank of the oil type R (step c in FIG. 9). Then, since the lubrication hose X is connected to the first discharge pipe 9 and the oil type is also regular (step d in FIG. 8), the indicator 6
1 indicates that lubrication is possible (Fig. 8 Step
E).

The first lubricating hose X and the second lubricating hose Y are not connected, and the identification lug reading means 25 of the first lubricating hose X is loaded with the hose identifying piece 34 of the second lubricating hose Y. If not (step F in FIG. 9), the process waits for the hose identification piece 34 of the hose Y to be loaded into the identification piece reading means 25 of the lubricating hose X of the hose X.

At the stage when the connection of the two lubricating hoses X and Y and the confirmation of the matching of the oil type are performed (step c in FIG. 8).
D) When unloading is instructed from the keyboard 61 (FIG. 8)
Step f), the bottom valve 5 is opened (step g in FIG. 8), and the fuel oil R is injected into the oil storage tank 15 from the hatch 1.

When the unloading is completed and an end command is issued from the keyboard 61 (FIG. 8 step), the hatch number “1” for which the unloading has been completed is input from the keyboard 61 (FIG. 8 step). Is closed (FIG. 8 step nu).

3, the first coupling 31 of the lubricating hose Y is connected to the coupling 11 of the discharge pipe 9 and the second coupling 32 is connected to the other lubricating hose X. The first coupling 21 is connected, and the second coupling 22 is connected to the coupling 17 of the oil supply pipe 16.
When the lubrication is performed by connecting the hose identification piece 34 of the lubrication hose Y to the hose sensor 13 of the discharge pipe 9, the hose identification piece 24 of the lubrication hose X to the identification piece reading means 35 of the lubrication hose Y, and further injecting. The oil type identification piece 18 of the oil pipe 16 is loaded into the identification piece reading means 25 of the oil hose X.

Then, the signal of the hose identification piece 34 is input from the hose sensor 13 to the control device 60 (step in FIG. 9).
D) Also, no signal indicating the oil type has been transmitted from the identification piece reading means 35 of the lubricating hose Y (step E in FIG. 9), and the hose data of the first lubricating hose X has been transmitted instead. Further, the oil type R is transmitted as a signal (in the flowchart, represented as “transmitter X ′”) of the identification piece reading means 25 of the first lubricating hose X (FIG. 9 Step T). Therefore, the determination means 67 determines that the discharge pipe 9 has been connected to the oil storage tank of the oil type R (step c in FIG. 9). Then, the determination means 67 displays on the display 61 that oil type regular R can be supplied from the discharge pipe 9 (step E in FIG. 8).
Hereinafter, lubrication is performed through the steps (f), (g), (h) to (nu).

It is apparent that the same process can be applied to the case where two oiling hoses X and Y are connected and oil is injected from the other discharge pipe 10.
