Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unloading system for tank lorry vehicles, and more particularly to a unloading system for tank lorry vehicles configured to unload oil liquid from a hatch to an underground tank without fail.

[0002]

2. Description of the Related Art Tank trucks are generally used as means for delivering oil liquid from an oil tank to a gas station or the like.

The tanks of tank trucks are divided into a plurality of hatches. For each hatch, depending on the order of the delivery destination, for example, the No. 1 hatch has gasoline, the No. 2 hatch has diesel oil, and the No. 3 has. Often, each hatch is loaded with an oil liquid of a different oil type, such as kerosene. Therefore, when the tank truck arrives at the delivery gas station,
The operator confirms that the type of oil in the underground tank is gasoline, for example, by looking at the nameplate or the like provided near the oil filling port of the underground tank. After that, attach one end of the oil supply hose to the tank truck.
After connecting to the oil supply port of the No. 1 hatch and connecting the other end to the oil supply port provided in the underground tank for gasoline, for example, open the on-off valve provided at the oil supply port of the hatch of the tank truck. The valve is unloading. At this time, the worker was allocating the hatch to the underground tank while looking at the slip.
Hereinafter, the same operation is performed when unloading light oil and kerosene.

However, conventionally, as described above, the operator determines the oil type of each hatch of the Lori vehicle and the oil type of the underground tank to determine the oil feeding port of the hatch of the Lori vehicle and the oil filling port of the underground tank. It was connected and unloaded via the oil supply hose provided in the Lori vehicle.

[0005]

However, in the conventional unloading system for tank lorry vehicles, at the time of unloading, the delivery destination manager attends and visually confirms the shipping slip, and from the tank with a sufficient remaining amount. It is necessary to perform the oil type allocation for the hatch, and when there are multiple tanks of the same oil type, unloading work is difficult to determine the priority order, and the unloading work cannot be performed efficiently. In addition, since a person decides the number of hatches that can be unloaded with respect to the remaining amount of the tank, there is a problem that the tank may overflow.

If one end of the oil supply hose is connected to a hatch in which gasoline is stored and the other end is connected to an underground tank in which light oil is stored and fuel is replenished, mixed oil will occur. There was a problem that it would end up. Further, even if the user makes a mistake in the connection as described above, there is a problem in that the oil supply hose must be reconnected.

The present invention has been made in view of the above points, and determines the underground tank corresponding to the hatch or the hatch corresponding to the underground tank before actually refueling the tank from the hatch of the tank truck. However, it is an object of the present invention to provide an unloading system for a tank truck that can efficiently perform unloading work by notifying a refueling operator of the determination result.

[0008]

According to the present invention, an information storage medium in which an oil type loaded in a hatch of a tank truck is stored corresponding to each hatch, and information stored in the information storage medium is read. Information reading means, tank oil type storage means for storing the oil type of the tank that receives the unloading from the tank truck, oil type for each hatch read by the information reading means, and tank oil type storage A hatch discrimination means for discriminating a hatch storing the same oil species as the oil species of the tank by comparing the oil species stored in the means;
And a notifying unit for notifying the discrimination result discriminated by the hatch discriminating unit.

[0009]

[Operation] The oil type data for each hatch pre-recorded on the information recording medium is read by the reading means, the oil type for each hatch and the oil type for each underground tank are compared, and the underground tank is assigned to the hatch. Therefore, the hatch can be assigned without causing oil mixture.

[0010]

The liquid level sensors 6-1 and 6-2 are connected to the liquid level gauge 7 provided in the office, and the underground tanks 3-1 and 3-2 are installed in the office.
It is configured so that the liquid level of can be monitored. The liquid level data displayed on the liquid level gauge 7 is connected to a console box 8 containing a hatch allocating means. In addition to the liquid level data, a grounding device 9 and bottom valve sensors 1c-1 and 1c-2 are connected to the console box 8 so that the ground connection and the opening / closing of the bottom valves 1b-1 and 1b-2 can be monitored. It is said that. The console box 8 controls the lubrication port interlock devices 5-1 and 5-2 based on these information.

As shown in FIG. 14, the console box 8 has a card reader section 8a and a printer section 8 which are reading means.
b, a buzzer 8c, a display 8d, and an operation unit 8e. As shown in FIG. 11, the card reader unit stores the vehicle number of the Lorry vehicle 1, the type of oil loaded in each hatch number, the quantity, and the customer number assigned to the customer as the delivery destination. The loaded Lori card is inserted, and those data are stored in the storage unit in the console box 8. The above data is stored in the lorry card at the oil tank when the oil liquid is loaded into the hatch of the lorry 1.

As shown in FIG. 12, the storage unit in the console box 8 stores the customer number, the oil type of the oil liquid entering the underground tank, and the capacity of the underground tank for each underground tank number. At the same time, as shown in FIG. 13, the oil type, the residual oil amount and the unloadable amount obtained by calculation from the data obtained from the volume level gauge 7 are stored for each underground tank.

Further, as shown in FIG. 14, the operation section 8e comprises operation keys 8e-1 to 8e-3 and display sections 8e-4 to 8e-6. The display portion 8e-4 is configured to correspond to a hatch, and the indicator lamp is turned on or off to know which hatch the display portion corresponds to. In addition, the display units 8e-5, 8e-6
Shows the display corresponding to the underground tank, and it is possible to know which underground tank is displayed by turning on and off the indicator light. Further, the operation keys 8e-1 and 8e-2 are provided corresponding to the underground tank, and the operation keys 8e-1
, 8e-2 is operated, the indicator light corresponding to the corresponding underground tank is turned on, and the indicator light of the corresponding hatch is turned on.

Next, the operation of unloading the oil liquid from the tank truck will be described with reference to FIGS.

First, when the lorry vehicle 1 arrives at the fueling station, the worker connects the bottom valve sensors 1b-1 and 1b-2 to the console box 8 and the connector for grounding to the lorry vehicle 1 (step S1). ).

Next, the worker inserts the lorry card into the card reader 8a of the console box 8 and loads the vehicle number data, loading data, delivery destination data, etc. stored in the lorry card as shown in FIG. (Step S
2).

Here, loading data and delivery destination data are stored for each hatch in the lorry card. The console box 8 compares the delivery destination data with the store number data given in advance to the gas station for each hatch (step S3),
If there is data that matches the store number data in the delivery destination data, the matching hatch oil type and quantity are stored in the memory provided in the console box 8, and the contents are displayed on the display unit 8
It is displayed in d (step S8). If there is no matching data in step S3, the display 8 indicates that the data is wrong.
Then, the display is displayed on the display 8d so that the Lori card can be read again (step S4).

When the driver reads the Lori card again in accordance with the instruction displayed on the display 8d (step S
5) The delivery destination data and the store number data are again compared (step S6), and if they match, step S8 is performed, and if they do not match, the display device 8d displays that the data is incorrect. If the data does not match again, the driver unloads the bill or the like (step S7).

When the data match in step 3, step 8
When is executed, the connection of the bottom valve sensor connector is next determined (step S9). If the data does not match the data given in advance to the gas station, the display 8d displays a message indicating that the bottom valve sensor is abnormal (step S10). The operator checks the connection of the connector and the bottom valve lever, and if there is no abnormality, presses the confirmation key (steps S11 and S12).
Here, in the console box 8, when the signals from the bottom valve sensors are not all closed, that is, when there is a hatch in an abnormal state, the operation unit 8e is operated to manually unload the oil liquid of all hatches. Select whether to unload only normal hatches by automatic control, and unload the abnormal hatches by manual operation (steps S13 to S15).

If the bottom valve sensor is in the correct state, then the ground connection is checked (step S16). If the ground is not properly connected, a display indicating that the ground is not correctly connected is displayed on the display 8d (step S17). The operator checks the ground connection and presses the confirmation key (steps S18 and S19). The ground connection is checked again (step S20).

If a message indicating that the ground is not connected is displayed again, the operator uses an alternative ground wire or manually operates (step S).
21-S23).

When the bottom valve and ground are checked, the console box 8 reads the liquid level data of the underground tank of the next oil type to be unloaded, and automatically allocates each underground tank and hatch (step S24). ..

In the automatic hatch allocation, as shown in FIGS. 9 and 10, first, in step S3, the allocation to the underground tank of the lorry 1 determines whether or not there are a plurality of undetermined hatches having the same store number. (Step 24-1). If there are a plurality of hatches for which allocation has not been determined, it is then determined whether or not there are a plurality of hatches loaded with the oil liquid of the same oil type (step S24-2). If there are a plurality of hatches having the same oil type, it is next determined whether or not there are a plurality of underground tanks having the same oil type (step S24-3).

When there are a plurality of underground tanks of the same oil type, the residual oil amount of the underground tank: the available unloading amount determined from the data stored in advance in the console box 8 is read (step S24-4).

Then, among the hatches having the same oil type, the hatch having the largest storage amount is discriminated (step S24-
Five).

Next, the determined storage amount of the hatch and the unloadable amount of the underground tank of the same oil type are compared to determine the unloadable underground tank (step S24-6).

Next, it is judged whether or not there are a plurality of underground tanks that do not overflow among the judged underground tanks (step S24-7).

Here, when there is only one judged underground tank, the hatch previously judged in step S24-5 is allocated to this judged one underground tank, and oil liquid is discharged from this judged hatch. The new residual oil amount and the possible unloading amount of the underground tank when unloading are calculated based on the storage amount of the hatch (the hatch determined in the previous step S24-5). Then, this calculation result is stored in the storage unit as the data of the underground tank to be used when allocating another unassigned hatch of the same oil type to the underground tank. The data corresponding to the hatch and the underground tank assigned to it are stored in the storage unit as automatic assignment data (steps S24-8 and S24-9).

Next, after this processing, the routine proceeds to step S24-10, where it is confirmed whether or not there is a hatch to which automatic allocation has not been made. That is, in all the hatches that require automatic allocation, if it is confirmed in this step that the hatches that have not been allocated remain, the process returns to the above-described step S24-1 and the remaining allocations that have not been completed yet. When it is confirmed that the allocation of all hatches has been completed while the processing shown in step S24-1 and subsequent steps is performed for the hatch, step S2 described later in FIG.
The process moves to step 5.

When there are a plurality of underground tanks that do not overflow in step S24-7, the underground tank having the largest unloadable amount among the underground tanks having the same oil type as the determined hatch is determined and determined. The underground tank is allocated to the hatch (step S24-12). After allocating the underground tank to the determined hatch, step S24
-8 to S24-10 are executed.

If there is only one hatch for which the underground tank has not been determined in step 24-1, the oil type and storage amount stored in the only one hatch for which automatic allocation has not been completed are read (step S24- 13 ). After determining the underground tank of the same oil type as that of the hatch (step S24
-14) Next, it is judged whether or not there are a plurality of underground tanks having the same oil type (step S24-15). Here, if there is only one underground tank of the same oil type as the undecided hatch,
Steps S24-8 to S24-10 are executed.

On the other hand, when there are a plurality of underground tanks of the same oil type as the hatch that has not been determined in step S24-15, the residual oil amount of these underground tanks: the unloadable amount is read from the storage device and stored in the hatch. The amount and the unloadable amount are compared to determine the unloadable underground tank (steps S24-16, S2).
4-17). Here, if there are several underground tanks that can be unloaded, that is, if there are multiple underground tanks that do not overflow,
When there is only one underground tank that does not overflow, the underground tank is directly assigned to the hatch (steps S24-18 and S24-19).

If there is only one hatch having the same oil type in step S24-2, steps S24-13 to S24-13.
S24-19 and S24-8 to S24-10 are performed, and the hatch is assigned to the underground tank. The contents of the allocation are displayed on the display 8e (step S25). Next, the operator operates the operation keys 8e-1 and 8e-2 of the underground tank to be unloaded according to the display, and inputs the underground tank No. to be unloaded (step S2).
6). When the underground tank No. (for example, underground tank 3-1) is input, the underground tank No. keyed in among the display units 8e-5, 8e-6 of the operation unit 8e is input based on the processing result of the automatic allocation processing described above. At the same time that the corresponding indicator light comes on, the hatch H of the Lori vehicle 1 is assigned corresponding to the underground tank No.
The display portion 8e-4 of the operation portion 8e corresponding to ₁ is turned on (steps S27 and S28).

Further, a control signal is sent from the console box 8 to the oil filler interlock device 5-1.
The oil inlet lock is released (step S29).

Next, the worker joins one end of the vapor line hose 9 to the vapor line 1f of the truck and connects the other end to the ventilation pipe 11 of the underground tank (step S30). The hatch H ₁ lit on the display portion 8e-4 is selected and connected to the unlocked underground tank 3-1 (steps S31 and S32).

Next, the bottom valve 1b-1 of the hatch H ₁ for unloading
To open (step S33). When the bottom valve 1b-1 is opened, the bottom valve sensor 1c-1 detects this, and the bottom valve open signal is input to the console box 8, and the allocated hatch H ₁
Is checked (step S3)
4, S35). Where the unassigned hatch H ₂
When a signal is input from the bottom valve 1b-2, the display 8d displays an error of the bottom valve and the buzzer 8c is activated (step S36). The operator operates the confirmation key to stop the ringing of the buzzer 8c, closes the bottom valve, and confirms the connection (steps S37 and S38). Underground tank 3-1
When the hatches H ₁ assigned to the two match, the display portions 8e-4 to 8e-6 provided on the operation portion 8e of the console box 8
, The indicator lights of the hatch H ₁ and the underground tank 3-1 corresponding to each other are blinked (step S39).

Next, the operator opens the main valve 1d-1 of the lorry 1 little by little, and fully opens it while confirming that there is no oil leakage (step S40). The console box 8 reads the liquid level by the liquid level sensor 6-1 (step S4).
1).

As for the read liquid level, the liquid level values within the sample time are averaged and stored in the internal memory (step S42).

Using the data in the memory, the previous average value is subtracted from the current average value, and it is determined whether or not the average value has increased (step S43). If the value obtained by subtracting the previous average value from the current average value is positive, it means that the underground tank 3-1 is being refilled with oil, so the start of unloading is detected and (Step S44). The above steps S42 to S44 are repeated to monitor the liquid level during refueling.

Next, if the value obtained by subtracting the previous average value from the current average value does not increase, it is judged that the unloading start has already started, and if the unloading start has not been detected yet, Monitor the surface level continuously. Further, if the unloading has started, then the average value at the start is subtracted from the current average value and the value is compared with the loading amount in the hatch H ₁ .
If it is within the error range, it is determined that the unloading is finished (steps S45 to S47). If it is not within the error range, the abnormality is notified by the buzzer 8c or the like and the unloading is interrupted (step S48).

After the completion of unloading is recognized, the display unit 8 of the operation unit 8e
The indicator lamps blinking at e-4 to 8e-6 are fixed to the lit state and the buzzer 8c is sounded to display the unloading amount (step S49).

In response to this, the operator operates the confirmation key of the operation section 8e of the console box 8 to confirm the end of unloading (step S50). In response to the operation of the confirmation key, the console box 8 stops the ringing of the buzzer 8c and turns off the display of the display units 8e-4 to 8e-6 (step S
51).

The worker removes the hose from the oil filling port of the underground tank 3-1 and locks the oil filling port (step S52). At this time, when the same underground tank 3-1 is filled with the oil liquid, the worker switches the joint on the hatch side while keeping the hose connected to the filler port.

Here, in the console box 8, it is judged by the key operation of the operator whether or not the operation is forcibly ended, and at the same time, it is judged whether or not the end of all unloading is completed (steps S53, S5
4). Here, the operator operates the operation unit 8 of the console box 8.
The end of unloading can be determined by looking at the display portions 8e-4 to 8e-6 provided on the e, and the unloading hose and the vapor line hose are tied up to complete the refueling work (step S
55).

If the unloading is not completed here, the process returns to step S25 and steps S25 to S55 are repeated.

Thus, when shipping data is set at the oil tank, the oil type and quantity for each hatch of the Lori vehicle are recorded in the Lori card, and the data of the oil type and the amount read from the Lori card at the delivery destination are stored in advance. By comparing the oil level and the liquid level data input from the level gauge for each underground tank, it is possible to surely assign the hatch from a tank with a small remaining amount, so that it is possible to prevent overflow of the tank and the hatch of the locomotive. Since the type and quantity of oil in the underground tank are compared and judged, mixed oil can be prevented.

As described above, since it is not necessary for humans to make hatch allocations, it is possible to prevent setting mistakes and improve work efficiency.

The customer code is recorded on the Lori card, and the customer code for each hatch of the medium at the time of unloading,
Since the SS code is unloaded and the customer data can be read by the console, it is possible to prevent erroneous unloading of the SS other than the instruction of the shipping slip.

[0055]

As described above, according to the present invention, the type of oil for each hatch read from the information recording medium: quantity data and data of the amount of residual oil in each underground tank input from the level gauge and each underground tank Since the hatch allocation is automatically performed by comparing with the data of the oil type of the above, it is possible to prevent the overflow of the underground tank, etc., and the comparison of the hatch of the Lori car and the oil type of the underground tank prevents the mixed oil. Moreover, since it is not necessary for humans to make hatch allocations according to judgment, setting mistakes can be prevented, and the efficiency of unloading work can be improved.
