Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shipping apparatus, and more particularly to a shipping apparatus configured to detect whether or not a previous oil liquid remains in a tank.

[0002]

2. Description of the Related Art For example, in a shipping device for shipping oil liquid, when a tank truck arrives at an oil liquid loading area, a vehicle number card of the tank truck is read. As a result, the upper-level management device of the oil tank station outputs the reservation data including the reservation quantity set for each tank hatch for the tank truck corresponding to the vehicle number data to the shipping control device at the shipping stage.

Next, the driver connects the grounding device to the tank truck, inserts and sets the loading arm of the oil type to be loaded in each hatch of the tank, and the hatch card reader provided in this loading arm is concerned. Have the reader read the hatch card that is attached to the filler port of the hatch with a chain. Next, the driver sets the loading amount by using the loading amount setting switch of the loading arm and operates the shipping start switch, and the shipping control device displays the oil type of the loading arm, the loading amount and the reservation data. The shipping permission signal is output on condition that the reserved oil type and the reserved quantity corresponding to the hatch match and that the earth interlock, the loading arm interlock, etc. are completed.

As a result, the pump that is communicated with the loading arm of the oil and liquid loading station is opened and the metering valve is opened, and the oil and liquid is loaded into each hatch of the tank truck. In addition, tank trucks are used at oil tanks after the amount of oil liquid reserved by the customer has been loaded into each hatch.
The customer visits the customer, such as the gas station where the order is placed, and unloads the oil in each hatch.

[0005]

However, if it is not possible to unload the oil solution at one gas station for some reason, the tank truck will return to the oil tank station with the oil solution remaining in the hatch, and Will be loaded with the oil solution at the delivery destination. Therefore, in the past, before inserting the loading arm into the oil filler port of the hatch, the driver checked whether the oil liquid remained in the hatch, and if the oil liquid remained, the oil liquid was hatched. The oil liquid was being loaded into the hatch after it was discharged from.

However, if the driver determines that there is no residual oil even though the oil liquid remains in the hatch, the oil liquid exceeding the quantity reserved by the customer will be loaded in the hatch. . For example, if the customer has reserved 2 kiloliters of oil, but there is still 1 kiloliter of oil previously loaded in the hatch intended to load the 2 kiloliters, There will be 3 kiloliters of oil in the hatch, and if the driver does not notice this, he will unload 3 kiloliters of oil to the customer.

Further, even if the oil type loaded last time is gasoline, if light oil is loaded this time, contamination (mixing accident of different oil types) will occur in the hatch.

Therefore, an object of the present invention is to provide a shipping apparatus that solves the above problems.

[0009]

According to the present invention, a loading arm is inserted in a tank of a tank truck, and a reserved oil type is loaded into the tank via the loading arm. A residual oil detecting means is provided for detecting the residual oil liquid in the tank, and when the residual oil detecting means detects the residual oil liquid in the tank, the residual oil liquid is shipped to the tank. It is characterized by comprising a control means for prohibiting.

[0010]

Since the tip of the loading arm is provided with the residual oil detecting means for detecting the oil liquid remaining in the tank,
By inserting the loading arm into the tank, it is possible to detect the presence or absence of the oil liquid previously loaded in the tank, and if the oil liquid remains in the tank, prohibit the shipping of the oil liquid to the tank. By doing so, it is possible to prevent inconsistency between the reserved quantity and the loading quantity, overflow during loading, or contamination.

Magnetically record reservation data of contents and loading data such as hatch numbers.

The shipping control device 27 transfers the vehicle number data to the host computer 32 of a higher level and receives the reservation data of the vehicle number data registered in the reservation file of the host computer 32.

Now, the shipping process executed by the shipping control device 25 will be described with reference to FIGS.

When the driver of the tank truck 2 arrives at the entrance of the oil tank, the driver inserts the magnetic card 33 into the card reader / writer 30.

In FIG. 5, the shipping control unit 25 executes step S1.
In (hereinafter, “step” is omitted), it is checked whether or not the vehicle number data stored in the magnetic card 33 is input from the card reader 30. When the vehicle number data is input, the process proceeds to S2 and the higher order Host computer 32
Transfer the car number data to.

In next step S3, it is checked whether or not the reservation data of the vehicle number data registered in the reservation file of the host computer 32 is received. When the reservation data is received from the host computer 32, the process proceeds to step S4 and the hatch is displayed. together to issue a voucher from the printer 31 performs loading oil species allocation for each hatch 2a ₁ to 2A region _n by setter 29, and records the reservation data and loading oil species assignment data to the magnetic card 33.

When the driver of the tank truck 2 receives the voucher and the magnetic card 33 at the entrance of the oil tank, he / she goes to the oil / liquid storage area 3 printed on the voucher. And, the driver
The magnetic card 3 is attached to the card reader / writer 26 provided in
After inserting 3, the ground connector 25 is connected to the vehicle body of the tank truck 2.

Next, the oil liquid loading process executed by the loading control device 16 installed in the oil liquid loading area 3 will be described.

In FIG. 6, in S11, it is checked whether or not the magnetic card 33 is inserted into the card reader / writer 26. In S11, the card reader / writer 2
When 6 is inserted into the magnetic card 33, the process proceeds to S12, where each data of the magnetic card 33 read by the card reader / writer 26 is checked.

In S12, when the data vehicle number data, the reservation data, and the oil type allocation data read from the magnetic card 33 are correct, the process proceeds to S13, in which the reservation data and the oil type allocation data are displayed on the display 24. , The oil type and loading amount for each hatch 2a _{1 to} 2a _n are set. However, if there is an error in the data on the magnetic card 33, the process proceeds to S14, and a "card error" is displayed on the display unit 24.

In the next step S15, it is checked whether or not the ground connector 25 is attached. If the ground connector 25 is not attached to the tank truck 2, the process proceeds to S16 and the display 24 displays the message "Earth connector attached".

However, when the ground connector 25 is attached in S15, the process proceeds to S17 and the display 24
Display the message "Earth connector OK" on.

Here, the driver of the tank truck 2 uses the loading arm 4 displayed on the display 24 to designate, for example, the first hatch 2 designated by the oil type allocation data.
It is inserted into the fuel supply port 2b ₁ of a _1. Then, the driver inserts the hatch card 17 ₁ of the hatch 2a ₁ into the hatch card reader 18 provided on the loading arm 4.

In the next S18, the hatch card reader 18
Check whether the hatch capacity or hatch number of the hatch card 17 ₁ has been read by. When the hatch capacity or hatch number is read in S18, S1
9 and it is checked whether the loading start switch 14 of the remote switch box 12 has been turned on.

When the start switch 14 is turned on in S19, the process proceeds to S20, and it is checked whether the micro switch 10 of the residual oil detector 6 is on. The hatch 2a
When there is no residual oil in ₁ , the residual oil detector 6 does not detect the residual oil, so the flow proceeds to S21, where the pump 22 is started and the metering valve 21 is opened to start loading of the oil into the hatch 2a ₁ . To do. In the next S22, the display unit 24 displays "Loading of oil liquid", and in S23, it is checked whether the integrated value from the flow meter 20 has reached the set value.

When the integrated value of the flow meter 20 reaches the set value in S23, the metering valve 21 is closed and the pump 22 is stopped. Then, in S24, it is checked whether or not all the oil and liquid of the reservation data have been loaded.

In S24, when there is still an oil type to be loaded, the process returns to S18 and the above-mentioned processings of S18 and thereafter are executed. However, when the loading of all the oil and liquid of the reservation data is completed in S24, the process proceeds to S25, the display 24 displays "loading completed", and the oil and liquid loading process is ended.

However, for some reason, the hatch 2a
_When the previously loaded oil liquid remains in ₁ , the residual oil detector 6 provided at the tip of the loading arm 4 rises against the spring force of the coil spring 9 while the float 8 contacts the liquid surface. Contact the microswitch 10. Therefore, the micro switch 10 outputs the residual oil detection signal.

Therefore, in S20, when the micro switch 10 is turned on, the process proceeds to S26, the shipping permission signal is not output (shipping prohibition means), and "there is residual oil" on the display 24.
Is displayed. Further, in S27, an alarm (shipping prohibition means) is sounded for a predetermined time to notify the driver. Then, the loading control device 16 returns to S19 again and executes the above-described processing from S19.

In this case, the driver connects the on-off valve (not shown) provided at the bottom of the hatch 2a ₁ to the residual oil collecting pipe, and then opens this on-off valve to open the hatch 2a ₁ The oil liquid remaining inside is extracted and sent to an underground tank or a storage tank. When the inside of the hatch 2a ₁ becomes empty, the driver closes the open / close valve and then turns on the loading start switch 14 again.

If a card error is displayed in S14, the loading control device 16 once terminates the processing of FIG.
The process returns to S11 again. Therefore, when the card error is displayed in S14, the driver again inserts the magnetic card 33 into the card reader / writer 30 of the hatch setting device 29 to store the reservation data and the allocation data of the loaded oil type in the magnetic card 33. To memorize. After that, insert the magnetic card 33 into the card reader / writer 26 of the oil liquid loading bay 3,
The loading control device 16 starts from the process of S11 described above.

When the installation of the ground connector is displayed in S16, the process returns to S15. That is, after the driver mounts the ground connector 25 on the tank truck 2 again, the mounting of the ground connector is confirmed in S15 and the process proceeds to S17.

[0045] However, when the loading to the remaining oil liquid in the hatch 2a _1, so that the hydraulic fluid that exceeds the quantity of hydraulic fluid that has been reserved from the customer is loaded on the hatch 2a _1. For example, if the quantity of oil liquid reserved by the customer is 2 kiloliters, but 1 kiloliter of oil liquid previously loaded in the hatch 2a ₁ remains, the hatch 2a ₁ will have 3 kiloliters. There will be liters of oil and if the driver does not notice this, he will unload 3 kiloliters of oil to the customer.

Furthermore, when 2 kiloliters of oil liquid previously loaded remains in the hatch having a capacity of 4 kiloliters, but when 3 kiloliters of oil liquid is loaded this time, an overflow occurs and 1 kiloliter of oil liquid is loaded. Spills out of the filler port. Also, even though the type of oil loaded the last time was gasoline, if light oil is loaded this time, contamination (accident of mixing different oil types) will occur in the hatch.

In this way, when the oil liquid previously loaded in the hatch 2a ₁ remains, the shipping permission signal is not output and the indication of residual oil and the alarm sound in S26 and S27. Never forget to pull out. Therefore,
Since the oil liquid is not loaded on the hatch where the residual oil remains, it is possible to prevent an overflow accident or a contamination accident due to the residual oil.

In the above embodiment, the loading control device 16 sounds the alarm in S27, and after the residual oil removing work, S
Although the process is returned to 19, the process is not limited to this, and the process may be terminated once in S27 and restarted from S11.

Further, in the above embodiment, when the residual oil loaded previously in the hatch was left, the draining operation was carried out. However, the present invention is not limited to this. For example, when the residual oil and the type of oil loaded this time match. It is also possible to perform the manual operation so that the loading amount matches the reservation data without performing the extraction work.

Further, although the residual oil detector of the above-mentioned embodiment is adapted to detect the residual oil by utilizing the float, instead of using the ultrasonic sensor or the optical sensor as a sensor for the residual oil detector. Of course, it is also good.

[0051]

As described above, the shipping apparatus according to the present invention is
Since the residual oil detecting means for detecting the oil liquid remaining in the tank is provided at the tip of the loading arm, the presence or absence of the oil liquid previously loaded in the tank is detected by inserting the loading arm into the tank. For example, if the oil liquid remains in the tank, loading of the oil liquid in this tank is prohibited, so that the loading of the oil liquid in the tank where the oil liquid remains can be prevented, and thus the reserved quantity and It has features such as inconsistency with the loading amount, overflow at loading, and prevention of contamination.
