Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shipping system, and more particularly, to a shipping system configured to easily perform an operation of shipping an oil liquid to a tank truck.

2. Description of the Related Art For example, in a shipping system for shipping an oil liquid, when the vehicle arrives at the shipping stage of a tank truck, the vehicle number card of the tank truck is inserted into a card reader and the vehicle number card is read, and the vehicle number card is read. Is output to the shipping control device. Then, a hatch card provided for each hatch of the tank is inserted into a card reader of the loading arm, and the hatch capacity is read. Then, after connecting the grounding device to the tank truck, the operator inserts the loading arm into the filler port of the hatch. Subsequently, if the loading amount set by the operator, the loading oil type and the reservation data, the hatch capacity match, and the earth interlock, the loading arm interlock, etc. have been completed, a shipping permission signal is output, and the shipping stage The oil is shipped to the tank truck by starting the pump and opening the metering valve.

Problems to be Solved by the Invention However, in the conventional shipping system, the hatch card is inserted into the card reader of the loading arm as described above, and the data of the hatch capacity stored in the hatch card is read by the shipping control device. When the set loading amount does not exceed the hatch capacity by comparing the loading amount set and operated by the operator, the oil liquid shipment is permitted to prevent overflow at the time of shipment. Conventionally, a card reader must be provided on the loading arm, and a hatch card must be provided on the tank truck, which increases the number of components in the shipping system and complicates the configuration, as well as the operator's operating procedures. There is a problem that it has become. Further, when the worker forgets to insert the hatch card into the card reader or loses the hatch card, it becomes impossible to ship the oil liquid, so that the handling of the hatch card is troublesome.

In view of this, the present invention detects the interval between each filler port provided in a plurality of hatches, and calculates the hatch capacity from the distance between the filler ports so that the operator does not need to input the hatch capacity. The purpose is to provide a configured shipping system.

Means for Solving the Problems The present invention provides a shipping system for loading a set amount of oil liquid into each hatch from a plurality of hatches provided in a plurality of hatches of a tank lorry vehicle. Detecting means for detecting the distance between each filler port provided respectively; hatch capacity calculating means for calculating each hatch capacity based on the distance between each filler port measured by the detecting means; and the hatch capacity calculation Means for comparing the hatch capacity calculated by the means with the set loading amount on the hatch, and permitting the start of shipping when the set loading amount does not exceed the hatch capacity.

When the tank lorry arrives at the shipping stage, the detecting means detects the distance between the hatch refueling ports, and calculates the hatch capacity based on the distance between the refueling ports, so that the hatch capacity can be automatically read. In addition, the worker's shipping work is simplified, and the shipping work efficiency is improved.

FIG. 1 to FIG. 3 show an embodiment of a shipping system according to the present invention.

Here, in the shipping system configured as described above, a process executed by the shipping control device 9 when loading the oil liquid into the tank truck 2 will be described with reference to FIG.

In FIG. 8, step S1 (hereinafter, step is omitted)
, The tank truck 2 before loading is in the shipping stage 3
, The driver inserts the vehicle number card into the card reader 3b, the vehicle number data is transferred to the host computer 8, and the shipment control device 9 sends the reservation data (loading oil type, loading amount) from the host computer 8. ) Is transferred. Next, when the driver attaches the ground connector 23 to the lorry vehicle 2, the ground interlock is released (S2). Subsequently, the loading arm 3a as in the first diagram is inserted into the hatch filler opening 17b of one hatch 15b, Location switch 3a ₁ releases the to the location interlock detecting the position of the loading arm 3a (S3).

When the driver operates the setting switch 19a of the remote switch box 19 provided on the loading arm 3a,
The loading amount is input (S4). And the shipping start switch
When 19b is operated (S5), it is confirmed that various interlock conditions (earth interlock, location interlock, etc.) are satisfied.

In S6, if at least one of the interlock conditions is not satisfied, the driver checks the shipping operation again, and returns to S5 when the interlock condition is satisfied in S7. or,
In S6, when all the interlock conditions are satisfied, the process proceeds to S8, in which the hatch in which the loading arm 3a is inserted (the second hatch 15b in this case) is adjacent to the hatch in the front-rear direction (the first hatch). Hatch 15a, third hatch 1
Measure the distance in 5c).

That is, when the tank truck 2 arrives at the shipping stage 3 as shown in FIGS. 2 and 3, the imaging camera 21 takes an image of the upper portion of the tank truck 2 from above as shown in FIG. The shipping control device 9 uses the hatch refueling ports 17a to 17g provided in each of the plurality of hatches 15a to 15g and the coordinate positions (x , y). Since the hatch refueling ports 17a to 17 of the tank truck 2 are arranged in a line in the front-rear direction of the tank truck 2, the tank truck 2 is set parallel to the image direction of the imaging camera 21 for the sake of simplicity. The case where the vehicle is stopped relative to the shipping stage 3 will be described as an example. Therefore, in this case, each hatch 17a-17
Have different x-coordinates and the same y-coordinate. Therefore, in this embodiment, the x-coordinate (x ₀
The distance between the front end portion of the tank 15 and the hatch filler opening 17a calculates the distance between the hatch filler opening 17a~17g than the difference ~x _8), and the distance between the rear portion and the hatch filler opening 17g of the tank 15 And calculate the hatch 15 located at the front and rear ends of the tank 15.
Find the hatch capacity of a, 15g.

Therefore, in the case of the present embodiment, the capacity of the hatch 15 is 1 kl, 2 kl,
Since a three 4kl, the distance A ₁ between adjacent each hatch ~A
_{6 (B 1 ~B 6), A} 1 (B 1); distance between hatch filler opening when the hatch each other are adjacent to each other in _{1kl, A 2 (B 2)} ; 1kl and 2kl hatch each other next to the Distance between hatch fillers when matching, A ₃ (B ₃ ); Distance between hatch fillers when 2 kl hatches are adjacent, A ₄ (B ₄ ); between 1 kl and ₄ kl hatches the distance between the hatch filler opening when the is adjacent to each other, a ₅ (B _5); the distance between the hatch filler opening when the hatch between the 2kl and 4kl are adjacent to each _{other, a 6 (B 6);} 4kl of The distance between hatch fillers when the hatches are adjacent at the same time, the following six distances, a table of hatch capacity as shown in FIG. 6 is obtained. Note that A _{1 in} the table of FIG. in matrix of to a ₆ and B ₁ .about.B ₆ Tokyo,
"-" results shown in A _{n = 1, .. 6} and B _{n = 1,} the combination of the _{.. 6} indicates that if not occur under the above conditions, for example, A ₂ and B ₂ When the combination is `` 1 or 2 '', the above conditions assume that each hatch refueling port 17a to 17g is located at the center of each hatch 15a to 15g in the front-rear direction, so that 2kl is sandwiched between 1kl hatches. When the capacity of the hatch is insufficient to be specified only from the distance between the hatch fillers, such as indicating that there is a hatch, or indicating that there is a 1kl hatch sandwiched between 2kl hatches Is shown. Then, in this case, the capacity of the next hatch is further specified, and the capacity of the hatch is specified based on the capacity.If the capacity of the next hatch is similarly insufficient, eventually, From the table shown in FIG.
, The capacity of the first hatch is specified first, then the capacity is sequentially specified from one end to the next hatch of the tank, and the capacity of the hatch is specified. As a result, as described above, the loading arm 3a is connected to the second hatch refueling port 17b.
, The distance between the second hatch refueling port 17b and the first hatch refueling port 17a is defined as the difference between x coordinates (x ₂ −x ₁ ).
= A ₆ , and the distance between the third hatch filler 17c and the second hatch filler 17b is determined from the x coordinate difference (x ₃ −x ₂ ) = B ₅ . The front and rear hatch filler opening spacing distance A _6, B ₅ from the hatch 15b
Is 4 kl (see FIG. 6).

Further, for example, the fifth hatch filler opening 17e when the loading arm 3a is inserted, 5th, 4th hatch filler opening 17e, the difference distance of the x-coordinate of _{17d (x 5 ~x 4) =} A ₃ , 6
The distance to the fifth and fifth hatch filler ports 17d and 17f is obtained from the difference (x ₆ −x ₅ ) = B _{3 in the} x coordinate. The hatch capacity of the hatch 15e is 2 kl from the front and rear hatch filler opening distances A ₃ and B _3.
Is calculated.

After calculating the distance between each hatch refueling port in S8 as described above, the distance between the front and rear hatch refueling ports is changed to the hatch capacity 1k in the next S9.
When it corresponds to l, it moves to S10 and the hatch capacity to be loaded is 1k
Recognize that l.

If the distance between the front and rear hatch filler ports does not correspond to the hatch capacity of 1 kl in S9, the process proceeds to S11. When it corresponds to the hatch capacity of 2 kl, the process shifts to S12 to recognize that the hatch capacity to be loaded is 2 kl.

If the distance between the front and rear hatch filler ports does not correspond to the hatch capacity 2 kl in S11, the process proceeds to S13, and if the distance corresponds to the hatch capacity 4 kl, it is recognized that the hatch capacity to be loaded is 4 kl (S14).

Subsequently, in S15, the driver switches the remote switch box 1
The setting amount (loading amount) set by the setting switch 19a of No. 9 is compared with the hatch capacity recognized in S10, 1S12, and S14.
If the set value does not exceed the hatch capacity in S15,
Then, the pump 12 is started and the metering valve 14 is opened to start loading.

When the loading to the second hatch 15b is completed in S17,
If there is a next loading schedule, the process returns to S3, and the above processing is repeated. If the set amount is larger than the hatch capacity in S15, an overflow is generated and an error is output, and the driver is informed of this by an alarm or the like. In this case, the process returns to step S4 to reset the set amount.

As described above, in this embodiment, when the tank lorry vehicle 2 arrives at the shipping stage 3, the hatch capacity is automatically detected based on the distance between the hatch refueling ports. No reader is required. Therefore, the configuration of the shipping system is simplified, and the number of operating procedures at the time of shipping by the driver is reduced, so that the operation can be easily performed. Therefore, at the time of shipment, the inconvenience of forgetting to insert the hatch card into the card reader, or losing the hatch card and making it impossible to ship is solved.

In the above-described embodiment, the imaging camera 21 captures an image of the upper portion of the tank 15. However, the configuration is not limited to this, and the position of the hatch refueling port may be detected using a sensor other than the imaging camera. Of course.

Effect of the Invention As described above, the shipping system according to the present invention can automatically set the hatch capacity from the position of each fuel supply port provided in a plurality of hatches, so that the conventional hatch card and The card reader can be dispensed with, the configuration can be simplified, and the shipping operation procedure can be reduced to improve the efficiency of the shipping operation. In addition, the present invention has the advantage that the trouble of forgetting to insert the hatch card into the card reader or of losing the hatch card and making it impossible to ship the product as in the related art is eliminated, and that a delay in shipping due to human error can be prevented.
