DETAILED DESCRIPTION OF THE INVENTION

[0001]

This invention has a plurality of hatches,
A first group of hatches located in front of the lorry is connected to a first common pipe via a bottom valve, and a second group of hatches located rearward is connected to a second common pipe via a bottom valve; The first and second common pipes are each connected to a hose connection coupling via a main valve, and the first and second common pipes are oil tanks for assigning a load to lorries connected to each other via a gate valve. Related to a shipping control device.

[0002]

2. Description of the Related Art The above-mentioned lorries can simultaneously perform unloading operations from a first and a second common pipe at a delivery station to which the lorry is delivered, respectively, so that the unloading operations can be streamlined. However, for that purpose, when loading at an oil depot, it is necessary to sort the cargo in advance.

[0003] This arrangement is effective when one lorry unloads at a plurality of gas stations.

[0004] As is well known, when the type of oil previously loaded on the lorry is the same as the type of oil loaded this time, and the last time is the second type petroleum (kerosene and light oil) and this time is the first type petroleum If it is (gasoline), gas loading is not required when loading the lorry, but if the previous time was Class 1 petroleum and this time it was Class 2 petroleum, there is a danger of explosion. The gas must be purged in advance and the gasoline vapor in the lorry hatch must be discharged. Since this gas purging operation usually requires 5 to 6 minutes, it is preferable not to perform gas purging by loading, for example, the same type of oil as much as possible. However, it is inevitable that a certain number of hatches are gas-purged by giving priority to simultaneous unloading work using a common pipe at a delivery station serving as a delivery destination.

[0005]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to control the shipment of an oil depot in which the simultaneous unloading by the first and second common pipes can be performed as much as possible and the gas purge can be minimized. In providing the device.

According to the present invention, a first group of hatches located in front of a lorry is connected to a first common pipe via a bottom valve, and a second group of hatches located behind. Is connected to a second common pipe via a bottom valve, the first and second common pipes are each connected to a hose connection coupling via a main valve, and the first and second common pipes are gate valves. In the shipping control device of the oil depot to allocate the load to the lorries connected to each other through, a master unit provided in the office and a plurality of slave units connected by signal lines with the master unit,
A slave unit including a control device, a card reader / writer, a keyboard, a display unit, and a printer, and the master unit storing tank data of a lorry including each hatch capacity and the first and second hatch groups; Previous load data storage means for storing the oil type of each previous hatch, load data input means for inputting the current unloading destination, oil type and oil amount, and first and second hatch groups for loading by destination. Allocating means, a gas purge determining means for determining whether gas purging is necessary or not based on the previous oil type and the presently allocated oil type, and re-setting so that the number of hatches required for gas purging is minimized. And reallocation means for performing allocation.
The automatically assigned load data can be modified by a keyboard, and the load data is stored and printed on a printer.

[0007]

[Explanation of the operation and effect] Therefore, when the lorry enters the oil depot, the control device preliminarily stores the tank data (capacity of each hatch, the first and second hatch groups) corresponding to the vehicle number of the lorry and the previous load. Data is stored. Then, when the cargo data is inputted by the cargo data input means such as the numeric keypad of the oil depot's keyboard or the computer of the distribution center, the allocating means allocates the cargo to the first and second hatch groups and can simultaneously load the gas at the gas station from the front and rear. And it is determined whether gas purging is necessary or not. The driver of Rori receives the load data from the office and carries out the loading operation according to the data. As described above, according to the present invention, the first and second common pipes can be loaded so that they can be used simultaneously at the time of unloading to a gas station, and the time required for gas purging can be minimized. And unloading work can be streamlined.

Therefore, the front first hatch groups H1 to H1
The oil of H3 and the rear second hatch groups H4-H6 can be simultaneously unloaded via the first and second hose connection couplings C1, C2, and in some cases, the front hatch groups H1-H3. The oil can be unloaded from the second hose connection coupling C2 via the gate valve B, and the oil of the rear hatch group H4 to H6 can be unloaded from the first hose connection coupling C1 via the gate valve B. You can also.

FIG. 2 is a plan view of an oil tank station A to be loaded by the tank lorry R. An office O is provided at an entrance G,
Various kinds of oil (for example, high-octane gasoline, regular gasoline, light oil, kerosene, etc.) are provided in an appropriate number of racks R1, R2.
Loading arms L1, L for refueling
2, L3 and L4 are provided. The office O is provided with a shipping control device indicated by reference numeral 1 as a whole.

FIG. 3 is an overall block diagram of the shipping control device provided in the office O. That is, the office O has a master unit indicated by reference numeral 2 and a plurality of (two in the illustrated example) slave units 3.
a, 3b are provided, and the master unit 2 and the slave units 3a, 3b are provided.
b are connected by signal lines L, respectively.

Since the slave units 3a and 3b have substantially the same configuration, only the slave unit 3a will be described, and the configuration corresponding to the slave unit 3a is illustrated with a suffix b.

The slave unit 3a is of a type known per se and includes a control unit 20a, a card reader / writer 21a and a keyboard 22a for inputting and outputting to and from the control unit 20a.
a and a printer 24a.

The tank data storage means 4 has a hatch capacity of each lorry, first and second hatch groups H1, H2, H3.H
4, H5 and H6 are stored, and the cargo data storage means 5 stores the last oil type of each hatch. The current load data is input from the load data input means 6.

The load data input means 6 may be input by using the numeric keypad of the parent machine 2, or may be a computer of a delivery center. An example of the cargo data is as shown in FIG.

That is, it is assumed that the lorry of the car number 1234 is delivered to two locations of the A service station (SS) and the B service station (SS) in the trip 3, and the regular 6 is used at the A service station.
kl and light oil 4kl are required.
It is assumed that 2 kl of kl high octane and 2 kl of kerosene are required. Therefore, 10kl high oct in total regular is 2
Kl gas oil loads 4 kl and kerosene loads 2 kl.

Therefore, when there is an input signal from the loading data input means 6, the tank data of the car number 1234 stored in the tank data storage means 4 is input, and the oil type of the previous loading is stored in the loading data. Input from means 5. Then, the loading possibility determination means 7 determines whether or not all can be loaded in order from the combination of the large hatch and the large amount. If the loading is not possible, a signal is sent to the annunciator 8 to notify.
For example, in the case of FIG. 4, it is possible, so the allocating means 9 performs the allocating operation from a large amount of unloading destinations, that is, from the service station A in the example of FIG. An example is shown in FIG.

In FIG. 5, hatch numbers 1 to 6 (H1 to
H6) and their respective capacities (the hatch H1 is 4 kl, the hatch H2 is 2 kl, the hatch H3 is 2 kl, and the hatch H4 is 2 kl.
kl, the hatch H5 is 4 kl, the hatch H6 is 4 kl) and the first hatch groups H1 to H3 are connected to the first common pipe T1, and the second hatch groups H4 to H6 are connected to the second common pipe T2. The connection means that the tank data storage means 4
The previous oil type, ie, the preload is hatch H1 regular, hatch H2 regular, hatch H3 light oil,
Hatch H4 is high octave, Hatch H5 is kerosene, Hatch H6
Is input from the cargo data storage means 5 as light oil.

As a result, the allocating means 9 stores a large amount, ie, A
First, regular 4 kl is assigned to hatch H1, regular 2 kl is assigned to hatch H4, and light oil 4 kl is assigned to hatch H5. Then, regular 4 kl hatch H2 is assigned to hatch H6 for hatch H6. 2 kl of high octane and 2 kl of kerosene to hatch H3.

Then, the gas purge determining means 10 determines that the gas purge is unnecessary in this case by comparing the last oil type of each hatch with the currently assigned oil type. However, as a result of comparing oil types, if the last time is the first petroleum and the current time is the second petroleum, it is determined that gas purging is necessary.

In the example shown in FIG. 5, there is no problem because gas purging is not required. However, when it is determined that gas purging is necessary in the practice of the present invention, the first hatch groups H1 to H
If the oil type is moved only in the third hatch group or only in the second hatch group H4 to H6, the gas purging becomes unnecessary. Further, when the gas purging is required only in the hatch group, the movement between the hatch groups is performed. Is determined by the reallocation means 11. For example, when kerosene is assigned to the hatch H2 and high octane is assigned to the hatch H3 in the example of FIG. 5, a gas purge of the hatch H2 is required.
It moves like. When the allocation is moved between the hatch groups, the possibility of simultaneous unloading is given priority over the presence or absence of gas purge.

The shipment control device 1 stands by in this state, and when the driver of Rori R reads the car number card into the card reader / writer 21a of the slave unit (for example, the slave unit 3a) of the office O,
The cargo data shown in FIG. 5 is displayed on the display 23a. The cargo data thus allocated can be corrected by the keyboard 22a. That is, the driver can make corrections according to the actual situation of the destination. Then, when the setting button of the keyboard 22a is pressed, the cargo data is stored in the vehicle number card and the shipping control device as corrected, and is printed out from the printer 24a. The current load data is updated and stored in the load data storage means 5. The driver receives refueling in the rack R1 or R2 based on the cargo data (for example, FIG. 5) printed out from the printer 24a.

As described above, according to the present invention, the allocation is performed properly and the gas purge is minimized, so that the loading and unloading efficiency is improved.

[0026]

As described above, according to the present invention, the following excellent effects can be obtained. (A) A hatch requiring gas purging can be minimized by the re-assignment means, and the loading work efficiency is improved. (B) Unloading can be performed simultaneously from two common pipes based on the data of the load data storage means, the tank data storage means, and the load data input means. (C) Since the loading data can be corrected using the keyboard, the driver can correct the loading data based on the arrangement of the lubrication port of the gas station, which is convenient. (D) Since the loading operation is performed on the rack based on the printed load data, the operation is also easy.
