Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a shipping control device for an oil depot equipped with a gas purge device and a refueling device.

``Prior Art'' As is well known, oil depots handle various types of oil, including regular gasoline, high-octane gasoline, kerosene, and diesel oil.
Each hatch of the lorry is supplied with different types of oil. However, it is not possible to specify the type of oil for each hatch of the lorry, and it is often the case that oil is supplied with a different type of oil from the previous one. In such cases, it is usually divided into a group of regular gasoline and high-octane gasoline, and a group of kerosene and diesel oil, and gas purge is not performed within each group, but when the groups are different, for example, when refueling with kerosene after gasoline. must perform gas purge of Lori's hatch. The reason for this is that when kerosene is refueled next to gasoline, the gasoline vapor becomes diluted and becomes easily flammable, and even a small amount can be dangerous due to contamination.

However, in the conventional technology, it was necessary to check the previous slip to determine which hatch was filled with which type of oil, which was cumbersome and was not accurate as it was all done at the discretion of the worker. Therefore, for safety reasons, it is preferable to purge all hatches with gas, but this reduces work efficiency.

[Object of the Invention] Accordingly, an object of the present invention is to provide a shipping control device for an oil depot, in which gas purging is always performed on hatches that should be purged with gas during refueling work, without relying on the memory or judgment of workers. There is something to do.

[Structure of the Invention] According to the present invention, in a shipping management device for an oil depot that is provided with a gas purge device and a refueling device, a storage device for storing the type of cargo oil for each hatch of a lorry; a determination means for determining whether the type of oil loaded last time and the type of oil loaded this time are the same; a determination means for determining the necessity of gas purging when the determination by the determination means is a different oil type; It is provided with a load permitting means for outputting to the gas purge device and permitting refueling by the refueling device in response to a purge end signal from the gas purge device.

[Operations and Effects of the Invention] Therefore, regarding the oil type stored for each hatch,
It distinguishes between the last time and the one to be refueled this time, and if it is determined that they are different types of oil, the gas purge device refills the oil with types of oil that must not be mixed, as it cannot be loaded unless it has been gas purged. There's nothing to do. There is therefore no risk that the gasoline vapor will become diluted and become easily flammable.

[Example 1] FIG. 1 is a plan view showing an oil depot in which the present invention is implemented, and an office 0 is provided near the entrance G to the oil depot.
A gas purge device 1 and an appropriate number of oil supply devices @ 2a, 2b, . . . are installed in the premises leading to the oil depot. The gas purge device 1 is provided with a gas purge pipe 16, a hatch sensor 6g is attached to the gas purge pipe 16, and a gas purge control m+ device 3 is further installed in the gas purge device 1.

The refueling device 2a has a rack 4, and loading arms 5a to 5d are provided on the rack 4 according to each type of oil. For example, the loading arm 5a carries regular gasoline,
The loading arm 5b supplies high-octane gasoline, the loading arm 5c supplies diesel oil, and the loading arm 5d supplies kerosene. Hatch sensors 6a to 6d are attached to each of these loading arms, and indicators 7a to 7d for displaying the amount of oil supplied from each loading arm are provided at easily visible positions. Further, the rack 4 is provided with a refueling control device 8.

Shipping control device 9 and gas purge device 1 installed in office O
The gas purge control device H3 provided in the rack 4 and the refueling control device 8 provided in the rack 4 are connected to each other by a signal line L1 to enable serial transmission.

The hatch sensors 6a to 6d and 6g each detect the hatch number of the lorry, and emit a signal corresponding to the hatch number and the oil type number of the loading arm to which the hatch sensor (-J4) is attached.

FIG. 2 shows the hatch of a lorry being purged with gas by the gas purge device 1 embodying the present invention. In the illustrated example, the lorry R parked in the gas purge area Ag has three hatches H1, H2, and H3.

Each hatch H1, H2, H3 has a hatch opening 10a, 10b, 10c in its upper part, and further has a hatch sensed lla, Ilb, 11c for each hatch.

On the other hand, the gas purge device 1 includes a base 12, on which a gas purge I control device 3 is erected, and this gas purge control device 3 is provided with a card reader 13 and other operation buttons 14.

Further, a blower 15 is installed on the base 12, and a gas purge pipe 16 is connected to its suction port.

The tip of the gas purge pipe 16 is inserted into the hatch opening. Further, a gas concentration detector 17 is provided in the middle of the gas purge pipe 16.

The discharge pipe 18 of the blower 15 extends to a safe location and is open, or is connected to a gas treatment device (not shown). A start switch 19 and a hatch sensor 6g are attached to the gas purge pipe 16. In the illustrated example, the hatched sensor 11b is connected to the hatched sensor 6g,
Gas purging of hatch H2 is shown. Even if each hatch of the lorry entering the oil depot A is empty, it is still full of vapor, so the vapor is extracted and replaced with air or inert gas.

FIG. 3 shows a refueling device 2a embodying the present invention, and in FIG. 2, the lorry R that has undergone gas purging is shown refueling. In the drawing, Hutch H2 is being refueled.

A fuel supply M control device 8 is installed upright on the rack 4, and the fuel supply control device 8 is provided with a card reader 21 and necessary operation buttons 22.

A fuel supply pipe 25 to which oil is sent from a fuel pump (not shown) is connected to the loading arm 5 through a flowmeter 26 and a control valve 27.

system) is established. In the figure, reference numeral 29 indicates a starting switch, and a location where the hatch sensor 11b of the hatch H2 of the lorry R is connected to the hatch sensor 6a is shown. Next, the operation will be explained with reference to FIGS. 4 and 5 (a), (0), and (c).

At the office O, the shipping data for each lorry R is stored in the storage means 9a of the shipping control device 9 in advance on the keyboard 3.
Enter 0 and give the driver a unique card. In addition to the keyboard 30, the shipping control device 9 includes a card reader 31, a printer 32, a display 33, a floppy disk 34 serving as an external memory, and the like.

When the lorry R arrives and reads the driver's card into the card reader 31 of the shipping control device 9 in the office O, the card data is input (step 81).

The shipping control device 9 has a storage means 9a, a determination means 9b, a determination means 9C1 and a load permission means 9d (FIG. 4), and the storage means 9a stores the previous cargo and current cargo data of the lorry carrying this card from the card data. The determination means 9b determines whether the oil type of each hatch is different, and the determination means 9C determines whether gas purge is necessary. Then, the cargo data and the judgment result are output to the printer 32, and a slip is issued (step 32). In this slip, hatches that require gas purging are marked, for example, in comparison with the previous cargo data. Then, with the slip in hand, the vehicle stops at area AQ using gas purge, connects the ground 50, and reads the card into card reader 13 of gas purge control bag w3 (step S3). Then, control bag W3 transfers the card data to office 0's shipping control bag @9.
The shipping control device 9 receives this signal (step S5) and sends data on hatches requiring gas purge to the gas purge control device 3 (step 86). The gas purge control device 3 receives this signal (step S1), and the gas purge control device 3
rn (step Sa>).

The driver looks at the slip, inserts the pipe 16 into a hatch that requires gas purging (for example, H2), and connects the hatched sensor 11b to the hatch sensor 6g. and start switch 19
Press. When the control device 3 determines that the correct hatch gas purge is performed, the blower 15 rotates, and after a certain period of time (for example, 2 minutes) has elapsed, when the signal from the gas concentration detection 117 is below a certain concentration, the gas purge is performed! 13111vt
Position 3 detects this and stops the blower. The gas purge device 1 is controlled in this way. In addition, in FIG. 4, the gas purge device 1 includes a blower 15, a starting switch 19,
This refers to the entire device including the gas S degree detector 17 and the like.

If there are other hatches that need gas purging, purge them in the same way. When the gas purge ends (step S9), the gas purge control device 3 sends a gas purge end signal to the shipping control device 9 (step 3 io). This completes the operation of the gas purge tIIlIIIl device 3 (end).

Shipment $11,611 Apparatus 9 confirms that all necessary hatch gas purge operations have been completed (i.e., step 81).
0) is received from the gas purge control device 3 (step S11). Then, the lorry is moved to the refueling area (for example, AI). If there are no hatches to purge, the train will stop directly at the refueling area.

In the refueling area, the driver connects the ground 51 and reads the card into the card reader 21 of the refueling control device 8 (step 512). Then, the refueling control device 8 sends the card data to the shipping control device 9 of office O (step 513).
), when the shipping control device 9 receives a card signal from the refueling control bag M8 (step 314), the loading permission means 9d of the shipping control device 9 determines whether the hatch of the lorry has completed the gas purge operation or not (step 815). ), if it has not been completed (step 816), the alarm 52 is activated.

In this case, refueling is not possible. If it has been completed, the refueling data for the lorry R is sent to the refueling control device 8 (step 517). When the refueling 11 control device 8 receives the refueling data (
Step 818), the refueling control device 8 performs refueling control of the refueling device 2a (step 519).

The driver inserts the loading arm into the hatch by looking at the slip, connects the hatch sensor 11b to the hatch sensor 6a, and presses the start switch 29. And the sub 1m device 8
If the operator determines that the oil type and hatch are correct, refueling will begin. The oil supply device 2a is controlled in this manner.

In FIG. 4, the oil supply device 2a includes a control valve 27 and a flow meter 28.
, a display meter 7a1, a start switch 29, etc.

Once all hatches have been refueled (Step 5)
20), the refueling control device 8 sends refueling end data to the shipping control device M9 (step 821), and the work of the refueling control device ends (end). If the shipping control device 9 receives the refueling end signal from the refueling 111ml device 8 (step 52
2), the shipping control device 9 stores the refueling data in the external storage device (step 523), and the operation ends (END).

Once the refueling work is complete, the driver disconnects the ground and leaves the vehicle.

In this embodiment, the data of the previous cargo on the lorry is taken out from the storage means 9a of the shipping control device M9, but the card reader 31 is made into a writable card reader encoder, and the data on the previous cargo on the lorry is taken out. The card may be used as a storage means by extracting the data from the card and writing the current cargo data onto the card.

[Summary] As described above, according to the present invention, if the gas purge is not completed, refueling is not performed, so the driver always performs the gas purge work according to the slip, so that, for example, gasoline vapor is not diluted and becomes easily flammable. It's safe.
