2. Description of the Related Art For example, in a shipping device for shipping oil liquid, when a tank truck arrives at a shipping stage, a driver connects a grounding device to the tank truck, and then rotates a shipping loading arm standing upright from the shipping stage. Move it and insert it into the hatch filler port of the tank truck.

Next, when the loading amount is set by the loading amount setting switch of the shipping loading arm and the shipping start button is turned on, the pump arranged upstream of the shipping loading arm is started. At the same time, the metering valve is opened to start loading of the oil liquid, and when the set amount of the oil liquid is loaded into the hatch, the metering valve is closed. When the loading of the oil liquid on the hatch is completed,
Carry out loading work on the next hatch.

As described above, in the shipping apparatus having the shipping loading arm, since the tank truck is provided with a plurality of hatches, the loading operation of the shipping loading arm and the withdrawal operation are performed for each hatch. In addition, a hatch setting device that automatically sets the type of oil to be loaded into each hatch of the tank truck based on the reservation data in which the order from the gas filling station is registered is installed at the oil depot,
This hatch setter allocates the oil type and quantity to be loaded to each hatch based on the reservation data of the ordered oil type and loading amount, but basically it is the hatch of the tank lorry vehicle in the previous shipping operation. The oil type is assigned so that the same oil type as the oil type shipped to is loaded.

Further, in order to efficiently deliver the oil liquid to a plurality of gas stations, there is a case where an oil liquid different from the oil type previously loaded in the same hatch of the tank truck is loaded and shipped. In this way, when loading a different oil type from the previous time, for example, when loading kerosene or light oil this time into the hatch that loaded gasoline last time and shipping / delivering it, before loading the oil liquid this time to the hatch to prevent danger. First, the hatch must be gas-purged and the vapor of the previous oil type remaining in the hatch must be discharged to the outside.

[0006]

However, in the above-described shipping apparatus, it may be forgotten to pull out the shipping loading arm from the fuel filler port of the hatch after the loading of the tank truck to the hatch is completed. In that case, the driver may start the tank truck without noticing that the shipping loading arm is still inserted in the fuel filler port of the hatch, and may damage the tank truck and the shipping loading arm. .

Even when performing the above-mentioned gas purging, after the completion of the gas purging, the tank lorry vehicle is started without forgetting to pull out the gas purging loading arm from the fuel filler port of the hatch and leaving the gas purging loading arm inserted in the hatch of the tank lorry vehicle. The tank truck and the gas purging loading arm may be damaged.

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

[0009]

In order to solve the above-mentioned problems, the invention of claim 1 inserts a loading arm for shipping connected to a liquid feed pipe for feeding an oil liquid from a standby position into a hatch of a tank truck. In the shipping device for loading the oil liquid into the hatch by moving it to the insertion position, the loading end judging means for judging that the loading of the oil liquid into the hatch of the tank truck is completed, and the shipping loading arm is inserted. From the position to the standby position, and the loading arm position detection unit does not detect that the shipping loading arm has returned from the insertion position to the standby position. And a notification means for issuing an alarm when the loading completion determination means determines that the loading of the oil liquid has been completed. A.

Therefore, according to the first aspect of the present invention, the loading arm position detecting means does not detect that the shipping loading arm has returned from the insertion position to the standby position, but the loading end determining means determines that the loading of the oil liquid has ended. By issuing an alarm when the determination is made, it is possible to prevent the tank lorry vehicle from starting after the loading of the oil liquid is completed and the shipping loading arm is inserted in the hatch of the tank lorry vehicle.

According to the second aspect of the invention, when loading a different oil type from the previous one into the hatch of the tank truck, the loading arm for gas purging is inserted from the standby position into the hatch of the tank truck before shipping the oil liquid. In the shipping device which moves the gas purging loading arm to the position and drives the exhaust pump connected to the gas purging loading arm to discharge the vapor remaining in the hatch to the outside, the gas purging loading arm is returned from the insertion position to the standby position. Loading arm position detecting means for detecting that the gas purging loading arm has been returned from the insertion position to the standby position after completion of the gas purging, and an alarming means for issuing an alarm. And are provided.

Therefore, according to the second aspect of the present invention, after the gas purging is completed, when the loading arm position detecting means does not detect that the loading arm for gas purging has been returned from the insertion position to the standby position, an alarm is issued to cause the gas purging. It is possible to prevent the tank lorry vehicle from starting while the loading arm for gas purging is still inserted in the hatch of the tank lorry vehicle after completion.

The insertion pipe 41 is inserted into the hatch oil supply port 2b while rotating the arm 36 downward.

In FIG. 6, the insertion pipe 41 has a hatch filler port 2b.
It is a front view showing the state where it was pulled up above. When the insertion pipe 41 is pulled upward from the hatch oil supply port 2b, the rotational position of the third arm 38 in the D direction changes.
Therefore, the vertical position of the insertion pipe 41 can be known from the relative displacement of the fourth joint 39 associated with the rotation of the third arm 38. Therefore, the first detection switch 4 a provided on the loading arm 4 has the fourth joint 39 associated with the rotation of the third arm 38.
The up-and-down position of the insertion pipe 41 due to the relative displacement of is detected.

FIG. 7 is a block diagram of the shipping apparatus. As shown in FIG. 7, the shipment control device 11 includes the first detection switch 4a, the second detection switch 5a, the alarm device 10,
Pump 15, flow meter 17, metering valve 18, loading setting device 2
5, connected to each device such as the hatch card reader 26, the card reader 27, the display 28, and the ground connector 29 to control each device. Further, in the shipping control device 11, as will be described later, a valve opening / closing control program that opens the metering valve 18 of the oil type set at the start of shipping and closes the metering valve 18 at the end of shipping, and as will be described later. After the loading of the oil liquid is completed, it is confirmed that the loading arm 4 is at the first standby position where the loading arm 4 is pulled out from the hatch or the loading arm 4 is at the second standby position where the loading arm 4 is returned to the shipping stage 3 side. When the loading arm 4 is not returned to the first or second standby position, the alarm device (notifying means) 10 issues a warning to prevent the driver from forgetting to remove the loading arm.

Here, the processing executed by the shipping control device 11 when the oil liquid is loaded on the tank truck 2 in the shipping device having the above-mentioned configuration will be described with reference to the flowcharts of FIGS. 8 to 10. When the tank truck 2 before loading arrives at the shipping stage 3, the driver connects the ground connector 29 to the vehicle body of the tank truck 2, and then inserts the vehicle number card 6 into the card reader 27.

In step S1 (hereinafter "step" is omitted), the ground connector 29 is set to the tank truck 2.
Whether or not it is connected to the vehicle body is judged from the presence or absence of the ground signal output from the ground connector 29. When it is determined in S1 that the ground connector 29 is not connected to the tank truck 2, the process proceeds to S2, and in S2,
Based on the detection signals from the first detection switch 4a and the second detection switch 5a, it is determined whether the loading arm 4 provided on the shipping stage 3 is at the second standby position held by the loading arm holding portion 5. To do.

When it is determined in S2 that the loading arm 4 is not held by the loading arm holding portion 5, the process proceeds to S3, an alarm is issued from the alarm device 10, and the process proceeds to S4. In this case, when the operator holds the loading arm not held by the loading arm holding unit 5 by the loading arm holding unit 5, S5
Then, the alarm of the alarm device 10 is stopped, and then the above-mentioned S
It returns to the process of 1.

Further, in S1, the ground connector 29
If there is another ground signal, it is determined that the ground connector 29 is connected and the process proceeds to S6. Also, S6
Then, the vehicle number data stored in the vehicle number card 24 is read by the card reader 27 and the vehicle number data is transferred to the host computer 8. Then, in S7, it is checked whether or not the reservation data (hatch number, loading oil type, loading amount, etc.) 42 corresponding to the vehicle number data as shown in FIG. 11 is input from the host computer 8.

If there is reservation data for the vehicle number data, the process proceeds to S9, where the reservation data (hatch number, loading oil type, loading amount, etc.) 42 transferred from the host computer 8 is stored, and the display is also provided. 28, the hatch number into which the loading arm 4 is inserted and the reserved oil type are displayed. However, when there is no reservation data for the vehicle number data, the process proceeds to S8 and the alarm device 10 issues an alarm.

The driver of the tank truck 2 is shown in FIGS.
, The loading arm 4a displayed on the display 28 is removed from the loading arm holding portion 5 and the insertion pipe 41 of the loading arm 4 is inserted into the hatch oil filler port 2b.
And the hatch card 24 of the hatch is inserted into the hatch card reader 26 provided in the loading arm 4 to read the hatch number stored in the hatch card 24.

In S10 of FIG. 9, the loading setting device 25
When the shipping start switch 25b is turned on, S1
The process proceeds to 1 and confirms that the quantity set by the loading quantity setting switch 25a of the remote switch box 25 is less than or equal to the quantity of reservation data received. If the set quantity is less than or equal to the acceptance quantity of the reservation data in S11, the process proceeds to S12, the quantity set by the setting remote switch 25a is stored, and the set quantity is subtracted from the acceptance quantity of the reservation data.

However, in S11, when the set quantity is not less than the acceptance quantity of the reservation data, the process proceeds to S13 and the alarm device 10 issues an alarm. In the next S14, the pump 1
Start 5. Further, in S15, a valve opening signal is output to the metering valve 18. Since the metering valve 18 is a two-stage open / close type, it is fully closed and then half opened, and after a while, it is fully opened.

The oil liquid is now shipped, and the flow meter 17
The output flow rate pulses are integrated (S16). In the next S17, it is checked whether or not the amount of oil liquid loaded has reached a set value for switching from full open to half closed.
When the oil-liquid loading amount accumulated in 16 reaches the set value, the process proceeds to S18, and the metering valve 18 is half-closed.

Further, in S19, it is checked whether or not the amount of oil liquid loaded reaches a set value for switching from half-closed to full open, and when the amount of oil liquid loaded reaches the set value, S is checked.
Proceeding to 20, the metering valve 18 is fully closed. This completes the loading of the liquid oil into the hatch.

In step S21 shown in FIG. 10, the pump 15
Delay stop. Then, in S22, it is checked whether or not the remaining (unloaded amount) of the reserved quantity of the oil type that can be supplied from the loading arm is zero. In this S22, if the remaining number of reservations is zero, S
23, the oil type lamp (not shown) is turned off.

When the driver of the tank truck 2 finishes loading the oil into the hatch as described above, as shown in FIG. 6, the insertion pipe 41 of the loading arm 4 is pulled out from the oil supply port 2b of the hatch and waits for the first waiting time. To the position,
When the next hatch is loaded with the oil liquid, the insertion pipe 41 of the loading arm 4 is inserted into the next hatch to continue the oil liquid loading operation. However, when all the types and quantities of oil to be loaded are loaded into the tank truck 2, the loading operation of the tank truck 2 is completed and the loading arm 4 is moved to the second standby position shown in FIGS. 2 and 3. It is returned and held by the loading arm holder 5.

Further, the worker disconnects the ground connector 29 from the vehicle body of the tank truck 2. In this way, when the loading arm 4 is returned to the second standby position and held by the loading arm holding portion 5, the detection switches 4a and 5 are detected.
Both b output a detection signal. Also, the ground connector 2
When 9 is removed from the vehicle body of the tank truck 2, the output of the ground signal from the ground connector 29 is stopped.

Subsequently, in S24, it is determined whether or not the loading by the other loading arm provided on the shipping stage 3 is completed, that is, the type of loading oil to be loaded by the tank truck 2 and the loading data stored in the reservation data. Check whether all the loaded quantities are loaded into the tank truck 2. If S
In 24, if the loading by the other loading arm is completed, the process proceeds to S25 and the ground connector 2
Whether or not 9 is removed from the vehicle body of the tank truck 2 is confirmed by the presence or absence of a ground signal from the ground connector 29.

In S24, if the reserved quantity remains, or if the loading of the oil liquid by another loading arm is not completed in S24, the process returns to S10 and the processes of S10 and thereafter are repeated. Then, in S25, when it is confirmed that the ground connector 29 is detached from the vehicle body of the tank truck 2, the process proceeds to S26, and all the loading arms 4 are loaded into the loading arm holding portion 5
It is judged whether or not it is held at the second standby position and is returned to the second standby position from the presence or absence of the detection signals from the detection switches 4a and 5b of each loading arm 4.

If the loading arm 4 is not held by the loading arm holding portion 5 and is not returned to the second standby position in S26, the process proceeds to S27, and the alarm device 10 issues an alarm. By the alarm of the alarm device 10, the driver of the tank truck 2 knows that the loading arm 4 is still inserted in the hatch refueling port 2b,
The operation of stopping the departure of the tank truck 2 and returning the loading arm 4 to the second standby position where the loading arm 4 is held by the loading arm holding portion 5 is performed.

However, in S26, when all the loading arms 4 are returned to the state of being held by the loading arm holding portion 5 (the second standby position), the series of processing is ended. As described above, in the present embodiment, when the ground connector 29 is removed from the tank truck 2 and the ground signal is not input from the ground connector 29, it is determined that the loading of the oil liquid on the tank truck 2 is completed, In this state, when the detection signals are input from the detection switches 4a and 5b, the alarm of the alarm device 10 is issued.

Therefore, even if the driver of the tank truck 2 forgets to pull out the loading arm 4 from the hatch oil supply port 2b after the loading of the oil liquid, the loading arm 4 is moved to the hatch oil supply port 2b by the alarm in S27. It is possible to prevent the tank lorry vehicle 2 from being started while it is inserted, and it is possible to prevent the tank lorry vehicle 2 and the loading arm 4 from being damaged.

Further, in this embodiment, when the loading arm 4 is removed from the loading arm holding portion 5 without connecting the ground connector 29 to the tank truck 2 in the above S1 to S5, the alarm device 10 issues an alarm. Therefore, it is possible to prevent oil liquid from being loaded on the tank truck 2 without connecting the ground connector 29 to the tank truck 2.

In the above embodiment, the insertion pipe 41 of the loading arm 4 is located at the first standby position in which the insertion pipe 41 of the loading arm 4 is lifted above the hatch refueling port 2b when all the oil liquids to be delivered are finished. Although the detection switches 4a and 5b are used to detect that the loading arm 4 is in the second standby position held by the loading arm holding portion 5, the present invention is not limited to this, and the loading arm 4 is in the first standby position or It may be configured to determine whether or not it is at the second standby position. In that case, the detection switch 4
Since it suffices to monitor the presence or absence of one of the detection signals of a and 5b, the other detection switch can be eliminated.

Further, in the above embodiment, the tank truck 2
Although the end of the loading of the oil liquid into the tank is detected by the fact that the ground connector 29 is detached from the tank truck 2,
It is not limited to this. For example, the type of oil to be loaded in the tank truck 2 and the loading quantity are all tank truck 2.
The end of loading of the oil liquid may be detected by detecting that the oil liquid has been loaded.

Further, in the above embodiment, by performing the control shown in the flow charts of FIGS. 8 to 10, it is possible to start the tank truck 2 with the loading arm 4 inserted into the hatch oil supply port 2b. Although it is prevented, instead of this control, for example, although the ground signal is not input from the ground connector 29 before the tank truck 2 arrives at the shipping stage 3, the detection signals from the detection switches 4a and 5b are transmitted. When it is input, the alarm of the alarm device 10 may be issued.

Further, instead of the detection switches 4a and 5b, the rotation angle of each joint of the loading arm 4 may be detected. For example, each joint 33, 35, 37, 39 of the loading arm 4 has A, B, C, D
Each rotational position detection sensor for detecting the rotational position in the direction is incorporated.

In the case where the rotational position detecting sensor is built in as described above, the rotational position of each arm in the directions A to D can be known from the combination of the detection signals output from each rotational position detecting sensor. Therefore, the shipping control device 11 is at the first standby position in which the loading arm 4 is pulled out upward from the hatch oil supply port 2b of the tank truck 2 based on the detection signal of the rotational position detection sensor provided for each joint. Whether the loading arm 4 is in the second standby position where the loading arm 4 is housed on the side of the shipping stage 3 and is held by the loading arm holding portion 6, or is the insertion position where the loading arm 4 is inserted into the hatch oil supply port 2b of the tank truck 2. Can be determined.

Further, the alarm device 10 may be either a device that gives a sound by means of a buzzer or the like or a device that can be visually confirmed by a lighting display of a lamp or the like, or a combination of both. FIG. 12 shows a second embodiment of the present invention.

When loading an oil type different from the previous one into the hatch of the tank truck 2, the driver of the tank truck 2 moves the tank truck 2 to the gas purge stage 51 before moving to the shipping stage 3. The gas purging stage 51 includes a loading arm 52 for gas purging.
Is provided.

Loading arm 52 for gas purging
Has the same configuration as the loading arm 4 for shipping, and thus the detailed description of the loading arm 52 is omitted. The loading arm 52 has a gas purge line 53.
An exhaust opening / closing valve 54 and an exhaust pump 55 that sucks the vapor in the hatch and discharges it to the outside are disposed in the gas purge pipe 53. A gas purge start button 56 is provided near the tip of the loading arm 52.

When the gas purge start button 56 is turned on, the gas purge control device 57 operates the exhaust on-off valve 54.
And the exhaust pump drive signal is output to drive the exhaust pump 55. Further, the exhaust pipe 59 connected to the exhaust side of the exhaust pump 55 extends to a high place sufficiently distant from the gas purge stage 51.
Therefore, the gas in the hatch sucked by the exhaust pump 55 is discharged to a safe place from the end of the exhaust pipe 59.

When the gas in the hatch is removed,
The gas purge control device 57 stops the exhaust pump 55 and closes the exhaust on-off valve 54. further,
The gas purge stage 51 has a first detection switch 61 for detecting that the loading arm 52 is in the first standby position, like the shipping stage 3 for shipping described above.
And a second detection switch 62 for detecting that the loading arm 52 is in the second standby position.

Therefore, when loading a different type of oil into the hatch of the tank truck 2, the loading arm 52 is connected to the hatch filling port 2 of the tank truck 2 as described above.
After inserting into b, the exhaust pump 55 is driven to perform gas purging. Then, as a method of detecting the end of this gas purging, a method of detecting the vapor concentration in the hatch of the tank truck 2 and determining that the gas purging is terminated when the vapor concentration falls below a predetermined threshold value, A ground connector 29 is connected to the tank truck 2 in order to prevent generation of static electricity when performing gas purging, and a method of determining that gas purging has ended when the ground signal from the ground connector 29 is turned off.
There is.

Therefore, when it is judged that the gas purging has been completed by any of the above methods,
If it is forgotten to pull out the loading arm 52 from the hatch refueling port 2b, it can be immediately detected by the detection switches 61 and 62.

Further, when the detection switches 61 and 62 do not detect the loading arm 52 after the completion of the gas purging, the gas purge control device 57 issues an alarm from the alarm device 63 to notify the driver. As a result, the tank truck 2
After the gas purging is completed, the driver of
Even if you forget to pull out from the hatch refueling port 2b,
It is possible to prevent the tank truck 2 from being started while the loading arm 52 is inserted into the hatch oil filler port 2b, and to prevent the loading arm 52 from being damaged.

The type of oil handled by the shipping device is not limited to the above-mentioned high-octane gasoline, regular gasoline, light oil, and kerosene, and the present invention is also applied to a shipping device for shipping a plurality of oil liquids to one loading arm. Of course you can.

As described above, according to the first aspect of the present invention, the loading arm position detection means does not detect that the shipping loading arm has returned from the insertion position to the standby position, but the loading end judgment is made. When the means determines that the loading of the oil liquid has ended, an alarm is issued, so after the loading of the oil liquid is completed, it is possible to prevent the tank truck from starting while the loading arm for shipping is still inserted in the hatch of the tank truck. It is possible to prevent the loading arm from being damaged.

According to the second aspect, after the gas purging is completed, an alarm is issued when the loading arm position detecting means does not detect that the gas purging loading arm has been returned from the insertion position to the standby position. Therefore, the gas purging is completed. It is possible to prevent the tank lorry vehicle from starting after the loading arm for gas purging is still inserted in the hatch of the vehicle for tank lorry, and to prevent the loading arm for gas purging from being damaged.
