Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to loading oil in the amount ordered by a customer into a lorry vehicle at an oil depot, and shipping the oil to a customer tank at the delivery destination. A lorry loading/unloading system that is used for loading and unloading from a vehicle, in particular, a lorry loading/unloading system that is configured to prevent different types of oil or different ordered amounts of oil from being loaded and unloaded into customer tanks at delivery destinations.・Regarding the loading and unloading system.

Conventional Technology For example, at an oil depot where oil liquids such as gasoline, diesel oil, kerosene, etc. are loaded into lorries and shipped, when an order is received from a customer such as a gas station, the customer's name, ordered oil type ( Reservation data such as loading oil type), order amount (loading amount), delivery port, etc. are input, and a delivery plan using lorries is created based on this reservation data. When the lorry arrives at the oil depot, the host computer reads the vehicle number card, and the host computer issues a delivery table containing the loading data, delivery destination, etc. corresponding to the lorry. After receiving the delivery list, the lorry vehicle heads to the shipping stage where the oil is loaded, and first the card reader installed at the shipping stage reads the vehicle number card. As a result, the type and amount of oil to be loaded into the lorry vehicle corresponding to the vehicle number are set in the loading control device of the shipping stage from the host computer. By the way, the tank of this lorry vehicle is usually divided into multiple hatches, and the capacity of each hatch is, for example, 4kI! .

They are different, such as 2kl and lkl. Therefore, since the type and amount of oil to be loaded into the lorry vehicle are set for each hatch, when loading oil into each hatch, use the hatch card provided for each hatch of the lorry vehicle. The hatch card reader installed on the loading arm of the shipping stage reads and verifies the hatches before loading oil into each hatch.

On the other hand, when a lorry truck loaded with oil at an oil depot arrives at a customer's service station and unloads the ordered oil into an underground tank at the service station, the liquid is stored in the underground tank. In order to prevent accidental loading and unloading of oil of a different type than the one being loaded and unloaded, connect the oil inlet of the hatch containing the oil to be loaded and unloaded from the lorry to the oil inlet of the underground tank using an oil supply hose. When this happens, we check the oil types of both. For example, a card with oil type data recorded is placed in advance near the oil filler port of an underground tank, and when loading and unloading, this card is read by a card reader installed on the oil supply hose, and the card is read by a card reader installed on the oil supply hose. When the type of oil in the tank does not match the oil in the underground tank, the loading/unloading valve installed at the oil inlet of the hatch of the lorry does not open.

However, in the lorry vehicle loading/unloading system as described above, the tank of the lorry vehicle is usually partitioned into a plurality of hatches, and the capacity of each hatch is, for example, 4.
kl, 2kl, l', etc., so when shipping the same oil type in multiple hatches, for example, 4kl of gasoline is loaded into the first hatch with a capacity of 4H, and 4kl of gasoline is loaded into the first hatch with a capacity of 2#7. Pour 2kl of gasoline into the second hatch of
In some cases, 1kl of diesel oil is loaded into a No. 3 hatch with a capacity of 1kl and shipped.

In such a case, when loading oil onto a lorry at an oil depot, the hatch card provided for each hatch on the lorry is read by the hatch card league installed on the loading arm at the shipping stage. Since the loading of oil is carried out while checking the loading oil type and loading amount for each hatch, there is no possibility of loading the wrong oil type, insufficient loading amount, etc.
There is no risk of overflow occurring.

However, when loading and unloading oil into an underground tank at a delivery destination gas station, as long as the oil type in the hatch to which the oil supply hose is connected matches the oil type in the underground tank, the oil in the hatch must be As loading and unloading is permitted, the following issues arise.

For example, the capacity of the underground gasoline tank at the destination gas station is 2kl, and 2kl of gasoline was loaded into the No. 2 hatch of the lorry into this underground tank! should be unloaded, but if a worker accidentally connects the fuel inlet of the first hatch loaded with 4kl of gasoline to the fuel inlet of this underground tank with a fuel hose. Even if a card with oil type data recorded near the underground tank's oil filler port is read by a card reader installed in the oil feed hose, the oil type matches, so it is inserted into the oil filler port of the hatch of the lorry vehicle. The provided loading and unloading valves will open and loading and unloading will be permitted. As a result, 4kl of gasoline was loaded and unloaded into an underground gasoline tank with a capacity of 2H, resulting in an overflow problem. In order to prevent the underground tank from overflowing due to such loading/unloading errors by workers, an overflow prevention valve must be installed in the underground tank.

Also, contrary to the above, the capacity of the underground gasoline tank at the destination gas station was 1', but the worker mistakenly placed the fuel inlet of the No. 2 hatch loaded with 2kl of gasoline. If the underground tank's oil filler port is connected to the oil supply hose, it will be possible to load and unload less oil than the ordered amount, which may cause problems if the ordered amount of oil is not accurately delivered to the customer. .

Therefore, an object of the present invention is to provide a lorry vehicle loading/unloading system that solves the above-mentioned problems.

Means and Function for Solving the Problems In order to solve the above-mentioned problems, the lorry vehicle loading/unloading system of the present invention uses a tank identification code attached to each delivery destination tank and an ordered delivery destination tank. each type of oil,
a shipping control means provided in the lorry vehicle, comprising a delivery data storage means for storing the oil amount in correspondence with the tank identification code, and creating a shipping plan for the lorry vehicle based on the delivery data storage means; a lorry vehicle storage means for storing, for each hatch, a tank identification code of a delivery destination where the oil loaded in the hatch is to be unloaded when loading the oil into the hatch based on the shipping plan created by the means; , the tank identification code attached to the tank to be delivered is compared with the tank identification code stored in the lorry vehicle storage means corresponding to the hatch that is about to load and unload oil into the tank, and the tank identification code is determined. When a match is found,
It is characterized by comprising tank verification means for permitting loading and unloading of oil liquid from the hatch.

Therefore, according to the lorry vehicle loading/unloading system of the present invention, when loading oil into the hatch of the lorry, the tank identification code of the delivery destination where the oil loaded in the hatch is to be unloaded is stored in the lorry vehicle storage means. When loading and unloading oil from the hatch of a lorry vehicle to the tank at the delivery destination, the tank identification code attached to the tank at the destination and the tank identification code attached to the hatch at the time of loading are stored. The system allows loading and unloading of oil after comparing it with the tank identification code stored in the lorry vehicle storage means. This system not only prevents people from loading and unloading oil, but also prevents them from accidentally loading and unloading oil that is the same type of oil but has a volume that is higher than the capacity of the tank at the delivery destination or a volume that is lower than the volume ordered. This allows for accurate loading and unloading.

Embodiment FIGS. 1 to 3 show an embodiment of the lorry vehicle loading/unloading system according to the present invention.

FIG. 1 is a schematic configuration diagram for explaining the processing at a delivery destination gas station, which is a customer, and the oil depot that receives an order from the gas station. In Figure 1, at a gas station, there are underground tanks IA and IB for each type of oil, such as gasoline, diesel oil, kerosene, etc.
, Ic are installed, and each underground tank i A-I
The C's differ not only in the type of oil they store, but also in their capacity; hypothetically, the capacity of the underground tank IA is 5kl, the capacity of the underground tank IB is 3#f, and the capacity of the underground tank IC is 2&j.
'. And each underground tank IA~
Each IC is pre-attached with a unique tank identification code. In the case of this embodiment, for example, the underground tank IA is "XA", the underground tank IB is "XB", and the underground tank IC is "XC" (where X is the fuel station identification code consisting of the telephone number of the gas station, etc. , A, B, and C are assigned tank identification codes in advance so as not to overlap with underground tanks of other gas stations, such as tank Nα) at the gas station.

Reference numeral 2 denotes a terminal device installed at a gas station office, etc., which is connected to, for example, a liquid level gauge (not shown) installed in each tank IA to IC, and manages the oil level in each tank IA to IC. It is. This terminal device 2 is connected to each tank I.
An ordering device 2a is attached that automatically instructs the oil depot to replenish oil when the remaining amount of A-IC decreases to a predetermined amount or less. The ordering device 2a is connected to an ordering device 4 at the oil depot via a communication line 3 such as a telephone line, and, for example, the terminal device 2 receives information indicating that the remaining amount of oil in the underground tank IA is a predetermined amount. If it is detected that the amount has fallen below 1', the ordering device 2a operates the input device of the terminal device 2 to send 4 farts of gasoline as the preset replenishment amount using the tank identification code "XA". The data is transmitted as order data to the order receiving device 4 at the oil depot.

Here, in this embodiment, the tank identification code "XA" and the oil quantity data "4kl" are transmitted as order data. You may also add day data.

On the other hand, in the case of this embodiment, the order receiving device 4 installed at the oil depot has the relationship between each tank identification code and the oil type stored in the tank corresponding to each tank identification code in advance. It is registered as a tank identification code-oil type table, and when the order receiving device 4 receives the order data, it stores the oil type corresponding to the received tank identification code in the order data consisting of this tank identification code - oil type, oil quantity data, etc. is created and output to a shipping management device 5, which will be described later.

In this embodiment, the order receiving device 4 has a tank identification code-oil type/oil quantity table, and identifies in advance each tank identification code and the oil type stored in the tank corresponding to each tank identification code. By registering the relationships between the above, oil type data and oil quantity data can be omitted as ordering data. Order data including oil type data and oil quantity data may be transmitted to the order receiving device 4 from there.

7 is a lorry vehicle, and the tank 7' of the lorry vehicle 7 is divided into three hatches 7a, 7b, and 7c, for example, and a hatch card 7a7b+ storing each hatch identification information is stored at the loading port of each hatch 7a to 7C. , 7c are provided. 15 is an on-vehicle oil mixture prevention device mounted on the lorry vehicle 7,

The lorry vehicle side connectors 18a to 18c are provided near each of the oil feed ports 16a to 16c, and the hose side connector 21 is connected to the lorry vehicle side connectors 18a to 18c, and the tank identification read optically. It consists of a converting section 26 that photoelectrically converts the drilling state corresponding to the code into a tank identification code and supplies it to the control means 27.

On the other hand, numeral 5 shown in FIG. 1 is a shipping management device installed at an oil depot, and based on order data including tank identification code, oil type data, oil quantity data, etc. supplied from the order receiving device 4, Create a delivery plan using lorries. This lorry delivery plan is based on the loading oil type data and the loading oil amount data in correspondence with the lorry vehicle identification data (for example, the lorry vehicle number, etc.) attached to the delivery port or on the lorry vehicle in advance.

It is configured by storing tank identification code data in association with the hatch of the lorry vehicle, and in connection with the loading operation, the shipping device 8 supplies oil to the lorry vehicle 7 as shown in FIG. 4 via the loading control device 6. It is configured to carry out liquid loading processing.

That is, when the lorry vehicle 7 arrives at the oil depot, the portable memory 28 provided in the on-vehicle oil mixture prevention device 15 is removed from the vehicle-mounted oil mixture prevention device 15, and the mobile memory 28 installed in the oil depot shipping control device 5 is removed. Attach it to a data reading/writing device. As a result, the shipping management device 5
The lorry vehicle identification data stored in the lorry vehicle identification area 28a of No. 8 is read (step Sl). Then, the shipping management device 5 searches the delivery plan for a delivery plan corresponding to the lorry vehicle identification data, and if there is a delivery schedule corresponding to the lorry vehicle 7, the shipping management device 5 searches for a delivery plan corresponding to the lorry vehicle identification data, and if there is a delivery plan corresponding to the lorry vehicle 7, the shipping management device 5 searches the delivery plan that corresponds to the lorry vehicle identification data. Each hatch 7a, 7b,
7c, the detection code for the delivery destination is “XA”, “
"XB" and "XC" are written (step S2).In addition, along with the process of reading the lorry vehicle identification data from the portable memory 28 in step S1, the shipping management device 5 writes the lorry vehicle 7
If the delivery schedule corresponding to the delivery schedule cannot be retrieved, error processing is performed as the lorry vehicle 7 is not in the delivery schedule.

Here, the portable memory 28 in which the shipping destination's tank identification code has been written in the Hatch Nα-tank identification code corresponding area 28b by the shipping management device 5 is removed from the data reading/writing device and reinstalled in the lorry vehicle 7. The oil mixing prevention device 15 is attached, and the lorry vehicle 7 is moved to a shipping stage in an oil depot.

As shown in FIG. 1, the shipping stage is provided with a loading control device 6 and a shipping device 8. The shipping device 8 has a liquid storage tank 9 that stores oil liquid on the base end side for each type of oil to be loaded.
A pump 12. Metering valve 13. A flow meter 14 etc. is installed, and this liquid supply pipe I
A loading arm 11 is connected to the tip side of the O, and is generally configured. On the other hand, the loading control device 6 measures the amount of loading oil using the flow meter 14 based on the loading data transmitted from the shipping control device 5, and also measures the amount of oil loaded using the pump 12 during loading. The drive control of the metering valve 13 is performed.

Next, the operation of loading oil onto the lorry vehicle 7 in this shipping stage will be described in detail.

When the lorry vehicle 7 that has completed the loading process shown in FIG.
It is attached to the data reading device (path shown) attached to the loading control device 6 installed on the shipping stage. The loading control device 6 is
Lorry vehicle identification area 2 of this attached portable memory 28
The lorry vehicle identification data stored in 8a is read and transmitted to the shipping management device 5. The shipping management device 5, which received the lorry vehicle identification data from the loading control device 6, stores the lorry vehicle identification data in association with the hatch of the lorry vehicle identification data (for example, 1. lorry vehicle number, etc.). The loading oil type data, loading oil amount data, and tank identification code data are transferred to the loading control device 6, and loading data for the lorry vehicle 7 is set in the loading control device 6.

After that, the operator performs the predetermined initial work (connecting the ground connector, etc.), and then checks the loading oil type, loading oil amount, hatch, etc. displayed on the display (illustrated path) of the loading control device 6. without checking the instructions, move the loading arm 11 of the shipping device 8 of the corresponding oil type to the corresponding hatch (for example, 7a
), and the hatch card 7a+ provided in the hatch 7a is read by a hatch card reader (path shown) provided in the loading arm 11.

Then, the loading control device 6 receives the loading oil type data sent from the above-mentioned shipping control device 5, which corresponds to the identification information of the hatch 7a read by the hatch card reader, and the loading oil by the loading arm 11. A comparison is made with the oil type, and if it is confirmed that the oil type matches, the loaded oil amount data sent from the above-mentioned shipping management device 5 is set as quantitative data, and then the pump 12 is permitted to drive. Then, when the operator operates a start switch (path shown) installed on the loading arm 11 similarly to the hatch card reader, the loading control device 6 starts the pump 12 and opens the metering valve 13. After that, loading of the oil progresses, and when the amount of oil measured by the flow meter 14 or the amount of oil corresponding to the amount of loaded oil data (quantitative data) is reached, the loading control device 6 closes the metering valve 13. The valve is turned on to stop the liquid supply and the pump is also stopped.

In this way, when the loading of oil into each hatch 78 to 7C is completed based on the operator's operation of the loading arm 11, etc., the data reading device attached to the loading control device 6 installed on the shipping stage It is removed, reattached to the vehicle-mounted oil mixture prevention device 15, and departed for the delivery destination.

FIG. 5 shows the process executed when the lorry vehicle 7 arrives at the delivery destination gas station and unloads oil into underground tanks IA to IC at the gas station.

Here, as an example of the loading/unloading operation, the operation for loading/unloading the light oil loaded into the hatch 7b and the processing executed by the vehicle-mounted oil mixture prevention device 15 will be described with reference to FIG. 5 as well.

First, the lorry vehicle 7 is stopped near the underground tank IB for light oil, and then the oil feed port connection part 20a of the oil feed hose 20 shown in FIG. 3 is connected to the oil feed port 16b of the hatch 7b, and the connector 21 is connected. Connect to the connector 18b on the lorry side.

The connector 18b is an optical fiber cable 25 and a conversion section 26.
Since it is connected to the control means 27 of the vehicle-mounted oil mixture prevention device 15 through the
Connect connector 21 to connector 18b, and at the same time connect hatch number data and corresponding tank identification code "XB
" is read from the portable memory 28 (step 311). Next, the oil filler port connection part 20b of the oil supply hose 20 is connected to the oil filler port 24 of the underground tank IB. Then, the above-mentioned card provided near the oil filler port 24 is 23 into the card reader 22 of the oil supply hose 20. Therefore, the tank identification code of the underground tank IB read by the card reader 22 "
XB'' is supplied to the control means 27 via the cable 21a, the connector 21.degree. 18, the cable 25, and the conversion section 26 (step S12).

Then, the tank identification code read from the card 23 of the underground tank IB is compared with the tank identification code read from the portable memory 28 (step S13), and if they match, the process goes from step S4 to step S15. A valve opening signal is supplied to the transfer solenoid valve 17b.

As a result, the light oil loaded in the hatch 7b is transferred to the oil supply hose 2.
0 to underground tank IB.

In this way, at the oil depot, each of the tanks IA to IB at the gas station is managed by the tank identification code, and the corresponding oil type is loaded into each hatch 7a to 7b. Therefore, it is possible to prevent gasoline from being unloaded into, for example, an underground tank IB for light oil and mixing different oil types in the tank.

The loading and unloading of light oil on Hutch 7b is completed, and the oil supply hose 20
When the reconnection parts 20a and 20b are removed, the connectors 18 and 2
1 (step 816), and supplies a valve closing signal to the solenoid valve 17b (step 517).
). As a result, the solenoid valve 17b is closed, and the loading and unloading work is completed.

Here, a case where the oil feed hose 20 is mistakenly connected to another hatch will be explained.

For example, if you intend to unload diesel oil into a diesel oil tank IB, you accidentally connect the connection part 20a of the oil supply hose 20 to the oil supply port 16a of the hatch 7a loaded with gasoline, and also connect the connector 21 to the connector 18a. Suppose it is closed. In this case, in step 311, the hatch number of the hatch 7a and the tank identification code "XA" are read.

Also, in step S12, the connection part 20b of the oil supply hose 17
The identification code of the card 23 read by the card reader 22 is “
XB''.

Therefore, in step S13, the identification code "XA" read from the portable memory 28 and the identification code "XB" read by the card reader 23 are compared. As a result, the tank identification code naturally does not match, and step S
14 to step S18, the alarm 19a of the hatch 7a connected to the oil supply hose 20 issues an alarm to notify the operator that the connection is incorrect.

The operator who noticed the incorrect connection due to the alarm disconnects the connection part 20a of the oil supply hose 20 from the oil supply port 16a of the hatch 7a, and also disconnects the connector 21 from the connector 18a, so that the connector is disconnected. is read (step 519).

Then, the alarm 19a is deactivated (step 520).
. After that, the operator reconnects the connection part 20a of the oil feed hose 20 to the oil feed port 17b of the hatch 7b, and steps Sll~
The process of S17 is executed.

Furthermore, even if Hutch 7a is loaded with 4kl of light oil, in the present invention, the underground tanks IA to IB are used instead of the type of oil.
In order to check the tank identification code of
Even if the oil supply hose 20 is connected to the oil supply port 16a, the tank identification codes do not match in step S14, and an alarm is issued as described above. Therefore, even if the oil types match, loading and unloading of the oil liquid will not start unless the oil supply hose 20 is connected to the hatch 7b loaded with light oil for the underground tank IB.

However, when comparing the oil type as in the past, 4kl of light oil loaded into Hatch 7a would be unloaded into underground tank IB, which would overflow from underground tank IB with a capacity of 3kl. .

However, in the present invention, since the identification codes of tanks IA to IB are used for verification, even if the same oil type is loaded in each hatch 7a to 7c, the oil liquid is dropped into an underground tank other than the underground tank set at the time of loading. This prevents

In the above embodiment, the lorry vehicle is provided with an oil mixture prevention device, but the oil mixture prevention device may be provided at a fueling station.

In that case, the fuel inlet of the lorry vehicle should be equipped with a card with the tank identification code recorded and a manual on-off valve, and the oil inlet of the underground tank should be equipped with a solenoid valve that is controlled to open and close by an oil mixture prevention device. Just do it.

In the above embodiment, the tank identification code may be written into the portable memory 28 when the lorry arrives at the oil depot, or may be written into the portable memory 28 after loading is completed at the oil depot.

Effects of the Invention As described above, the lorry vehicle loading/unloading system of the present invention is managed at an oil depot in accordance with the oil type, oil amount, or tank identification code for each tank of the delivery destination for which an order is placed. It is possible to accurately load oil into the corresponding hatch, and furthermore, it is possible to load and unload the oil loaded into the hatch based on the tank identification code set for each tank at the delivery destination at the filling station. It is possible to reliably prevent oil liquids of different oil types from being unloaded, and it is also possible to prevent different oil types from being mixed at the delivery tank. Furthermore, instead of checking the oil type data between Hatsuchi and the tank at the delivery destination,
Since the tank identification code can be used to determine whether the hatch is the same or not, even if the same type of oil is loaded into hatches with different capacities, oil from other hatches may be mistakenly unloaded, resulting in overflow or overloading. It has features such as being able to prevent inconveniences such as insufficient unloading volume and eliminating the need for an overflow valve.
