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 simplify gas purging equipment in an oil tank and to save gas purging work and shipping work.

[0002]

2. Description of the Related Art When an empty tank truck arrives at an oil tank station for shipping oil to the tank of a tank truck, the type of oil reserved by the shipping device and the amount of oil to be supplied to each hatch of the tank truck. It will be shipped. However, since there is a small amount of oil liquid that was previously supplied at the hatch bottom of the empty tank truck that has unloaded the oil liquid, the vapor gas is evaporated in each hatch due to evaporation of the remaining oil liquid. It is full.

However, the oil liquid supplied this time is not always the same as the oil type used last time, and for example, light oil may be loaded this time in the hatch in which gasoline was loaded in the previous time. May be loaded with an oil liquid of a different oil type from the previous time.

However, when the oil liquid B of another oil type is loaded into the hatch filled with the vapor gas of the previous oil liquid A, the vapor gas of the different oil liquid A and the vapor gas of the oil liquid B are different in the hatch. As a result of being mixed, the ignition temperature of the vapor gas is lowered depending on the mixing ratio with the oil type or the air, and it is easy to catch fire.

Therefore, in the shipping apparatus, when an empty tank lorry vehicle arrives, the tank lorry vehicle is first stopped on the gas purging stage, the gas purging loading arm is inserted into the hatch insertion port, and vapor gas in the hatch is sucked to the outside. To discharge. Then, vapor discharge is continued until the vapor gas concentration in the hatch becomes less than the dangerous concentration, and when the vapor gas concentration becomes less than the dangerous concentration, the gas purging loading arm is pulled out from the hatch insertion port, and the gas purging operation is completed.

After that, the tank truck is moved to a shipping stage and an oil liquid shipping operation is carried out to each hatch.

[0007]

In the conventional shipping apparatus, since the gas purging stage and the shipping stage are provided in different places, the site of the oil tank must be widened, and the gas purging stage and Since the various equipment and control device at the shipping stage are separately installed, there is a problem that the control system becomes complicated. Furthermore, conventionally, the tank truck has had to move between the gas purging stage and the shipping stage, and it takes time from the arrival at the oil tank to the end of the reserved oil liquid, which is a burden on the operator. Was great. Moreover, conventionally, since the control devices of the gas purging stage and the shipping stage have to communicate with the host computer separately, the number of times of communication is large and the processing time of the host computer is extra.

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

[0009]

According to the present invention, an oil liquid shipping loading arm and a gas purging loading arm are provided on the same stage, and the previous oil type and the current oil type are based on the vehicle number data of the Lori vehicle. The stage is provided with a control means for judging whether or not there is a gas purge for each hatch of the lorry vehicle by comparing with, and outputting a liquid supply permission signal when the gas purging is not necessary and outputting a gas purge permission signal when the gas purging is required. It is characterized by

[0010]

[Operation] Since the loading arm for oil liquid shipping and the loading arm for gas purging are provided on the same stage, it is not necessary to move the tank truck when gas purging is required, and the oil liquid can be loaded in a short time accordingly. Will be able to finish. Further, the equipment of the oil tank can be simplified and the number of times of communication with the host computer can be reduced.

As shown in, the gas purging display device 17 displays the presence / absence of gas purging, the type of oil at this time, and the hatch capacity for each hatch 25a to 25g. In this embodiment, gas purge is displayed only when the oil type used this time is different from that used this time.

At the same time, as shown in FIG. 7, FIG. 8 and FIG. 9, a column of reservation data for each hatch, loading data and vehicle data is displayed on the shipping display device 16 based on the reservation hatch information from the host computer 23. Let

With this, the operator can know the hatches that need to be gas-purged by the gas-purging display device 17, and can know the type of oil to be loaded in each hatch and the loading amount by the shipping display device 16.

Next, the process executed by the gas purge point control device 20 together with the gas purging operation will be described with reference to FIG.

First, the operator finds the second and third hatches 25b and 25c from the display on the gas purging display device 17.
After confirming that the gas purging is required, the gas purging loading arm 3A is inserted into the hatch insertion port 30c of the third hatch 25c. Then, the hatch card 31c of the hatch 25c is inserted into the card reader 36 of the gas purging loading arm 3A to read the hatch information such as the hatch number and the hatch capacity stored in the hatch card 31c.

Further, the operator is required to set the gas purge setting device 33.
Set the hatch capacity to 2 by using the hatch capacity setting switch 33a.
After setting to kiloliters, the gas purge start button 33b is pressed.

The gas purge point controller 20 is shown in FIG.
In S21 shown in (1), it is checked whether or not the data stored in the hatch card 31c from the card reader 36 and the hatch capacity from the gas purge setting device 33 are input. Therefore, from the card reader 36 to the hatch card 31c
Data and the hatch capacity is input from the gas purge setting device 33, the process proceeds to S22 to check whether the gas purge start button 33b is turned on.

In S22, when the gas purge start button 33b is pressed and turned on, the process proceeds to S23 and it is checked whether gas purge is necessary. That is, as described above, when the stage control device 22 determines that the gas purging is necessary, the process proceeds to S24 and it is checked whether the gas purging is completed.

If the gas purging is completed in S24, S
28, the gas purging completion lamp 33c of the gas purging setting device 33 is blinked to notify that gas purging is unnecessary.

However, if the gas purging is not completed in S24, the process proceeds to S25 to perform the gas purging process. That is, the exhaust fan 13 of the gas purge line 6 is started and the solenoid valve 15 is opened to suck the vapor in the hatch card 31c.
Therefore, the vapor in the hatch card 31c is sucked by the gas purging loading arm 3A, and the purge pipe 12
It is discharged to the outside via.

The gas purge control device 20 sets the purge time according to the hatch capacity to start the air exhauster 13, and after the purge time elapses, the vapor concentration sensor 14 is activated.
When the residual concentration in the hatch is detected and the vapor concentration decreases to the lower limit value or less, the exhaust fan 13 is stopped and the solenoid valve 15 provided in the purge pipe 12 is closed.

When the gas purging process of S25 is completed, S
After storing the gas purge completion in 26, the gas purge completion lamp 33c of the gas purge setting device 33 is blinked in S27 to notify the completion of the gas purge.

The operator confirms that the gas purging process for the hatch 25c is completed by blinking the gas purging completion lamp 33c, and confirms that the gas purging loading arm 3A.
Is pulled up from the hatch insertion port 30c of the hatch 25c, the gas purging loading arm 3A is inserted into the hatch insertion port 30b for purging, and the above operation is repeated.

When the gas purging of the hatch 25c is started, the worker inserts the oil-liquid shipping loading arm 2A into another hatch that does not require the gas purging, and carries out the shipping work.

That is, the operator confirms from the display of the gas purging display device 17 that the gas purging of the first, fourth, and seventh hatches 25a and 25d to 25g is unnecessary, and the loading arms 2A, 2C, and 2D for shipping are checked. Hatch 2
5a, 25e, 25g hatch insertion ports 30a, 30e,
Sequentially insert into 30 g. And each hatch 25a, 25
The hatch cards 31a, 31e, 31g of e, 25g are inserted into the card reader 35 of the loading arms 2A, 2C, 2D for shipping, and the hatch cards 31a, 31e, 31g are inserted.
Read the hatch information such as hatch number and hatch capacity stored in.

Further, the operator presses the shipping start button 32b after setting the hatch capacity with the hatch capacity setting switch 32a of the shipping setting device 32.

In step S31 shown in FIG. 11, the shipping point control device 19 controls the hatch reader 3 from the card reader 35.
It is checked whether or not the data stored in 1a, the hatch capacity, and the oil type are input from the shipping setter 32. Therefore, when the data of the hatch card 31a is input from the card reader 35 and the hatch capacity and the oil type are input from the shipping setter 32, the process proceeds to S32 to check whether the shipping start button 32b is turned on.

In S32, the shipping start button 32
When b is pressed and turned on, the process proceeds to S33 to check whether gas purging is necessary. That is, as described above, when the stage control device 22 determines that the gas purging is necessary, the process proceeds to S34 to check whether the gas purging is completed.

If gas purging has been completed in S34, S
35, and it is checked whether or not the reserved type of oil to be loaded and the type of oil of the loading arm 2A for shipping are the same. However, in S34, when the gas purging is not completed, the process proceeds to S43, and an alarm (not shown) informs that the gas purging is necessary. This prevents forgetting the gas purge.

When the oil type is the same in S35, S36
Then, it is checked whether or not the quantity (loading quantity) set by the shipping setting device 32 is less than or equal to the reserved quantity for loading (reserved load quantity). However, in S35, when the oil types do not match, the process proceeds to S44, and an alarm (not shown) is used to give a warning of occurrence of contamination (misclusion of different oil types). This prevents the occurrence of accidents of mixing different oil types during shipping.

In the case of S36 or less, the process proceeds to S37 to check whether the set quantity (loading quantity) is less than or equal to the hatch capacity. However, in S36, if the quantity (loading amount) set by the shipping setting device 32 is not less than the reserved load quantity (reserved load quantity), S45.
Then, the alarm (not shown) informs that the overload exceeds the reserved quantity. This prevents overloading during shipping.

In S37, in the following cases, the process proceeds to S38,
The reservation data for each hatch is updated to the reservation data for the hatch to be loaded next. However, in S37, if the set quantity (loading quantity) is not less than or equal to the hatch capacity,
Moving to S46, a warning of overflow occurrence is notified by an alarm (not shown). This can prevent an overflow accident due to a setting error in the shipping setter 32.

Then, the metering valve 11 of the shipping line 5 is opened to start the shipping of the oil liquid (S39). As a result, the oil liquid in the liquid storage tank 7 is supplied into the hatch 25a through the liquid supply pipe 8 and the shipping loading arm 2A.

Then, the liquid supply amount loaded in the hatch 25a is measured by the flow meter 10 and the flow rate pulse output from the flow meter 10 is counted to calculate the loading amount (S4).
0). When the quantity (loading quantity) set by the shipping setting device 32 is supplied to the hatch 25a in S41, S4 is executed.
2, the metering valve 11 is closed and shipping of the oil liquid is stopped.

This completes the normal shipping process for the hatch 25a.

The above-mentioned series of shipping processing is performed by the other hatches 25d.
It is also sequentially executed for 25 g. In this embodiment, since the gas purging work and the oil liquid shipping work to the tank truck 4 can be simultaneously performed in the same stage 1 in this way, the tank truck 4 is shipped to the gas purging stage after being shipped as in the conventional case. Since it is not necessary to move to the stage, it is possible to shorten the time from the arrival at the oil splitting tank to the completion of all shipping work, and the labor of the worker.

Further, the facility work for constructing the stage 1 is simplified and the construction cost is reduced. Further, since the host computer 23 can communicate with the shipping point controller 19 and the gas purge point controller 20 via the stage controller 22, the number of communications between the host computer 23 and the stage 1 is reduced, and the host computer 2
The burden of 3 can be reduced.

In the above embodiment, the gas purging loading arms 3A and 3B are installed on each side of the stage 1 by one point. However, the present invention is not limited to this, and a plurality of gas purging loading arms may be installed on both sides of the stage 1. May be. Further, the installation location of the gas purging loading arm is not limited to the above-described embodiment (see FIG. 2), and it may be provided, for example, at the end of the stage 1 so that the gas purging loading arm can be swung to both sides of the stage 1.

Further, in the above embodiment, the shipping display device 16 for displaying the reservation data (hatch number, oil type, loading amount, etc.) to be loaded onto the tank truck 4 on the stage 1, and the gas purging device for displaying the gas purging data and the like. Although the display device 17 is separately provided, the present invention is not limited to this, and it goes without saying that one display device may display the reservation data and the gas purge data.

[0057]

As described above, the shipping apparatus according to the present invention is
Since the loading arm for oil liquid shipping and the loading arm for gas purging are provided on the same stage,
Even when gas purging is necessary, the tank truck does not have to be moved, and the loading time from the arrival of the tank truck at the oil tank to the completion of shipping can be shortened by that much, and the loading of oil liquid can be completed in a shorter time than before. It is possible to reduce the labor of the worker. Moreover, since gas purging and oil liquid loading can be performed simultaneously for one tank truck, that is, while one tank hatch vehicle gas purging is performed, the other hatch can be loaded with oil fluid.
A series of gas purging operations and shipping operations for tank trucks can be efficiently performed. Further, the oil tank facility is simplified, the construction cost can be kept low, and the number of times of communication with the host computer can be reduced to reduce the load on the host computer.
