[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tank truck having a function of determining an oil type when fuel oil is replenished to an oil storage tank installed at a gas station and preventing the injection of a different oil type.
[0002]
[Prior art]
When fuel oil is replenished from the tank truck to the oil storage tank, it is necessary to confirm the match between the oil type to be replenished from the hatch and the oil type of the oil storage tank in order to prevent mixed oil. Because it relies on manpower, mistakes can sometimes occur.
For this reason, as described in Japanese Patent Laid-Open No. 3-249380, oil type determination means is provided in the male coupling provided in the discharge pipe of the lorry, and oil is provided in the female coupling provided in the oil supply pipe of the oil storage tank. There has also been proposed a type having protrusions having different lengths depending on the seeds, and mechanically transmitting the lengths of the protrusions to the oil type determining means by means of wires inserted into the oiling hose.
[0003]
However, since the result of oil type determination is transmitted through the wire, there is a risk that a determination error will occur due to an error due to play or elongation of the wire, and the passage cross-sectional area becomes smaller by accommodating the wire, and the time required for lubrication There is a problem such as becoming longer.
In order to solve such a problem, the present applicant has previously connected a plurality of hatches connected to a discharge pipe having a first coupling via a bottom valve and a first coupling connectable to the first coupling. In the lorry for unloading the oil storage tank by an oiling hose provided with a coupling of No. 2 and a third coupling of the oil storage tank, the third coupling is provided in the vicinity of the fourth coupling. An identification piece reading means for reading an oil type identification piece provided near the coupling and outputting it wirelessly, a signal received from the identification piece reading means, and the received reading result and the oil type of the hatch number from the keyboard In comparison, we proposed a tank truck with control means that can open the bottom valve specified by the keyboard if they match.
[0004]
[Problems to be solved by the invention]
According to this, the oil type data of the identification piece indicating the oil type of each oil storage tank can be received by radio signal, the oil type can be judged with high reliability, the effective cross-sectional area of the lubrication pipe is not reduced, and the unloading time However, when the distance between the position where the lorry can stop and the lubrication pipe is longer than the length of one lubrication hose, multiple lubrication hoses mounted on the tank lorry are connected in series. Even if it tries to connect and lubricate, since the coupling of each hose cannot be connected, it has the inconvenience that lubrication at a long distance becomes impossible.
The present invention has been made in view of such problems, and the object of the present invention is not only to determine the oil type with high reliability, but also to connect two lubrication hoses in series for a long time. It is to provide a tank truck that can be unloaded at a distance.
[0005]
[Means for Solving the Problems]
In order to achieve such a problem, in the present invention, the first coupling that can be connected to the first and second discharge pipes connected to each of the plurality of hatches via the bottom valve is provided at one end, The other end includes a first coupling and a second coupling hose having a second coupling connectable to a coupling of an oil storage pipe of the oil storage tank, and first and second oiling hoses. A hose identification piece provided in the vicinity of the first coupling, a hose identification piece provided in the vicinity of the second coupling of the first and second oil supply hoses, and in the vicinity of the oil supply pipe of the oil storage tank. An identification piece reading means for reading the provided oil type identification piece and outputting it by a radio signal, a hose sensor provided in the vicinity of the discharge pipe for reading the hose identification piece, and a radio reception for receiving a signal from the identification piece reading means Means and hatch number input When receiving a signal from the keyboard, a hose sensor, a wireless signal from the identification piece reading means, and a signal indicating the oil type from the identification piece reading means of the lubrication hose connected to the discharge pipe, or a different lubrication hose When a signal indicating the oil type is received from the identification piece reading means, the signal indicating the lubrication hose from the identification piece reading means of the other lubrication hose is received, and the signal from the identification piece reading means and the hatch from the keyboard are received. A control means for comparing the number of oil types with each other and allowing the bottom valve designated by the keyboard to be opened when they match is provided.
[0006]
[Action]

[0017]
Next, the operation of the apparatus configured as described above will be described based on the flowcharts shown in FIGS.
(When unloading is performed with one lubrication hose)
When unloading is performed from the hatch 1 communicating with the first discharge pipe 9, the first oil supply hose X is lowered from the vehicle and the first coupling 21 is connected to the coupling 11 of the first discharge pipe 9. The second coupling 22 is connected to the coupling 17 of the lubrication pipe 16.
Then, the hose identification piece 24 is loaded into the hose sensor 13 of the discharge pipe 9, and the oil type identification piece 18 provided in the oil supply pipe 16 is loaded into the identification piece reading means 25.
[0018]
Next, after issuing an instruction to start unloading with the keyboard 61 (FIG. 8 Step A), when the hatch number “1” is input with the keyboard 61 (Step 8 in FIG. 8), the connection judgment of the lubrication hoses X and Y and the oil type A determination is made (FIG. 8, step C).
[0019]
That is, a signal (represented as “sensor A” in the flowchart) associated with insertion of the hose identification piece 24 is input to the control device 60 by the switch 52 of the hose sensor 13 (step A in FIG. 9). The oil type in the oil storage tank 15 recorded in the oil type identification piece 18 of the oil pipe 16 is read, a radio signal (represented as “transmitter X ′” in the flowchart) is transmitted from the radio transmission means 44, and the oil type R is input. (Step 9 in Fig. 9). Then, 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).
[0020]
Based on the hatch number “1” input from the keyboard 61, the determination unit 67 stores the data of the discharge pipe number “1” and the oil type “regular” stored in the storage unit 65 as shown in FIG. Read out and determine the difference between the discharge pipe number and the oil type in the previously determined state, that is, “discharge pipe 9 is connected to oil storage tank of oil type R” (step C in FIG. 8). Is connected to the first discharge pipe 9 and the oil type also matches (step D in FIG. 8), the display 61 indicates that oiling is possible (step E in FIG. 8).
[0021]
In addition, when the oil type of the designated hatch and the oil type of the oil storage tank 15 do not match, a notification is given by the notification device 63 (step in FIG. 8).
[0022]
Next, when unloading is instructed (step F in FIG. 8), the bottom valve 5 of the hatch 1 is opened (step FIG. 8), and fuel oil of oil type R is injected into the oil storage tank 15.
[0023]
When unloading is completed and the end command is given from the keyboard 61 (step 8 in FIG. 8), and the number “1” of hatch 1 that has now been unloaded is input from the keyboard 61 (step 8 in FIG. 8), the bottom of hatch 1 The valve 5 is closed (Step 8 in FIG. 8).
[0024]
Moreover, when unloading using the second oil supply hose Y, it can be performed by going through the same process as described above.
That is, a signal accompanying the insertion of the identification piece 34 is input by the switch 52 of the hose sensor 13 (FIG. 9 Step D), and the identification piece reading means 35 of the oil storage tank 15 recorded in the identification piece 18 of the lubrication pipe 16 is recorded. The oil type R is read, a signal is transmitted from the wireless transmission means 44, and the oil type R is input (step 9 in FIG. 9). Then, 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).
[0025]
Based on the hatch number “1” input from the keyboard 61, the determination unit 67 stores the data of the discharge pipe number “1” and the oil type “regular” stored in the storage unit 65 as shown in FIG. Read out and determine the difference between the discharge pipe number and the oil type in the previously determined state, that is, “the discharge pipe 9 is connected to the oil storage tank of oil type R” (FIG. 8 Step C). Is connected to the first discharge pipe 9 and the oil types match (FIG. 8 Step D), the display 61 indicates that oiling is possible (FIG. 8 Step F). Lubricating can be executed through the steps (f), (h), (h) to (n).
[0026]
(When unloading by connecting two lubrication hoses X and Y)
When the distance between the position where the lorry 10 can stop and the oil supply pipe 16 is longer than the oil supply hoses X and Y, the oil supply hoses X and Y are connected to execute oil supply.
[0027]
That is, as shown in FIG. 3, the first coupling 21 of one lubrication hose X is connected to the coupling 11 of the discharge pipe 9 and the second coupling 22 is coupled to the first coupling of the other lubrication hose Y. 31 is connected, and the second coupling 32 of the oil supply hose Y is connected to the coupling 17 of the oil supply pipe 16.
[0028]
After that, the oil type identification piece 24 of the lubrication hose X is used as the hose sensor 13 of the discharge pipe 9, the hose identification piece 34 of the lubrication hose Y is used as the identification piece reading means 25 of the lubrication hose X, and the oil type of the lubrication pipe 16 is used. The identification piece 18 is loaded into the identification piece reading means 35 of the lubrication hose Y.
Next, after issuing a command to start unloading with the keyboard 61 (FIG. 8 Step A), when the hatch number “1” is entered with the keyboard 61 (Step 8 in FIG. 8), the connection judgment between the lubrication hose X and the lubrication hose Y is performed. Or, oil type determination is executed (FIG. 8, step C).
[0029]
That is, the signal of the hose identification piece 24 is input from the hose sensor 13 to the control device 60 (FIG. 9 Step A), and the oil type data is not transmitted from the identification piece reading means 25 of the lubrication hose X (FIG. 9). 9), the hose data of the second oiling hose Y is transmitted instead (step F in FIG. 9), and the signal (in the flowchart, “transmitter Y” in the identification piece reading means 35 of the second oiling hose Y). The oil type R is transmitted as “)” (step 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). Since the oil supply hose X is connected to the first discharge pipe 9 and the oil type is also regularly matched (FIG. 8 Step D), the display 61 indicates that oil supply is possible (FIG. 8 Step H). ).
[0030]
The first lubrication hose X and the second lubrication hose Y are not connected, and the identification piece reading means 25 of the first lubrication hose X is not loaded with the hose identification piece 34 of the second lubrication hose Y. In the case (step F in FIG. 9), it waits for the hose identification piece 34 of the hose Y to be loaded into the identification piece reading means 25 of the lubrication hose X of the hose X.
[0031]
When the connection between the two lubrication hoses X and Y and the confirmation of the oil type coincidence are performed (Fig. 8, Step C, D), when the unloading command is issued from the keyboard 61 (Fig. 8, Step F), the bottom valve 5 is opened (step in FIG. 8), and fuel oil R is injected from the hatch 1 to the oil storage tank 15.
[0032]
When unloading is finished and the end command is given from the keyboard 61 (step 8 in FIG. 8), and the hatch number “1” at which unloading is finished is input from the keyboard 61 (step 8 in FIG. 8), the bottom valve 5 is closed. (Step 8 in FIG. 8).
[0033]
3, the first coupling 31 of the lubrication hose Y is coupled to the coupling 11 of the discharge pipe 9 and the second coupling 32 is coupled to the first coupling 31 of the other lubrication hose X. When the coupling 21 is connected and the second coupling 22 is connected to the coupling 17 of the lubrication pipe 16 for lubrication, the hose identification piece 34 of the lubrication hose Y is connected to the hose sensor 13 of the discharge pipe 9. The hose identification piece 24 of the lubrication hose X is loaded into the identification piece reading means 35 of the lubrication hose Y, and the oil type identification piece 18 of the lubrication pipe 16 is loaded into the identification piece reading means 25 of the lubrication hose X.
[0034]
And the signal of the hose identification piece 34 is input from the hose sensor 13 to the control device 60 (FIG. 9 Step D), and the signal indicating the oil type is not transmitted from the identification piece reading means 35 of the oiling hose Y (see FIG. 9). FIG. 9 Step E), instead, the hose data of the first oil supply hose X is transmitted (FIG. 9 Step H), and the signal of the identification piece reading means 25 of the first oil supply hose X (“transmitter” in the flowchart). The oil type R is transmitted as “X ′” (step 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, the determination means 67 displays on the display 61 that the oil type regular R can be injected from the discharge pipe 9 (step E in FIG. 8), and the following steps (F), (G), (H) to (H) Lubricating is performed through the process of No.).
[0035]
Further, when two oiling hoses X and Y are connected and lubricated from the other discharge pipe 10, it is obvious that the same process can be followed.
