Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container terminal capable of efficiently unloading or loading containers when land transporting containers transported by sea.

[0002]

2. Description of the Related Art Conventionally, in a container terminal, for example, to unload a container from a container ship to a stock yard, the container is directly transferred to an automatic guided vehicle by a gantry crane arranged on an apron on a quay, and the container is mounted. The automatic guided vehicle moves through a predetermined track into the stock yard, where the container is delivered to an overhead crane or a transfer crane. Loading from the stock yard to the container ship is performed by the reverse operation.

In order to unload a container stored in a stock yard to a truck for land transportation, the container is transferred to a delivery point by an overhead crane, and
The container is delivered to a truck or transferred by a transfer crane, and the automated guided vehicle passes through a predetermined track, enters a stock yard, and delivers the container by an overhead crane. In the case of loading, the above procedure is reversed.

[0004]

However, in a conventional container terminal, a gantry crane, an overhead crane or a transfer crane is used for loading and unloading containers from a container ship to a stockyard and from a stockyard to a truck. Is an automated guided vehicle (or truck)
Or the automatic guided vehicle (or truck) needs to match the moving pace of the crane, which is inefficient.

For example, between a container ship and a stock yard, even if a gantry crane attempts to load a container on an unmanned carrier, if the unmanned carrier is not waiting at the delivery point of the gantry crane, the gantry crane waits at the delivery point. In the meantime, the container will not be unloaded from the container ship during this time.

[0006] The above phenomenon also occurs in an overhead crane or a transfer crane between a stock yard and a truck (or an automatic guided vehicle). For example, an overhead crane also needs to transship containers in a stock yard, so when a truck stops at a delivery point, it is necessary to suspend the transshipment operation or wait until the operation is completed.

That is, in the above situation, the transfer operation of the container at the delivery point relies on a gantry crane, an overhead crane, or a transfer crane. If the timing is shifted, the flow of the container in the container terminal stops, and the efficiency of the cargo handling operation is reduced as described above. Further, since the above-described automatic guided vehicle cannot hold the container on which it is placed, it is necessary to wait for the container to be transferred from above by a crane, which further reduces the efficiency.

An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide a container terminal capable of efficiently performing a cargo handling operation without stopping a flow of the container during the cargo handling operation.

[0009]

In order to achieve the above object, a container terminal according to the present invention includes a gantry crane, a stock yard, and a truck terminal. The overhead traveling crane is placed in the yard and the container is moved between the stockyard and the gantry crane and the truck terminal using a plurality of container carriers. By doing so, the gantry crane, the overhead traveling crane, and the truck can perform the delivery or reception of the container with any of the plurality of container carriers.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The container terminal of the present invention
A container terminal that is a relay point between sea transportation and land transportation, comprising at least one gantry crane for unloading or loading containers between an apron on a quay and a ship, and unloading of the gantry crane. Or, a stockyard arranged near the loading point for temporarily storing containers, and a truck terminal arranged on the opposite side of the stockyard from the gantry crane arrangement side, and the stockyard is arranged in a plurality of rows, and An overhead traveling crane is arranged in a row, and a container is moved between a stock yard and a gantry crane and a truck terminal by using a plurality of container carriers. It is desirable to have at least two units in each row of the yard, and if necessary Between the truck terminals and stockyards Te is obtained by placing the elevated-shaped trajectory container carriers travel.

[0011] According to the above configuration, for example, when unloading a container from a ship, a plurality of gantry cranes unload the container at a place where the container is not placed among the container delivery points. Container carrier
When arriving at the container delivery point of the gantry crane, the container carrier is held here and travels to a row of the stockyards arranged in multiple rows where the container carrier is not stopped, the container is unloaded here, and the gantry is returned again. Travel to the delivery point of the crane. On the other hand, in the stock yard, the container unloaded from the container carrier is held by an overhead traveling crane, and the container is placed and stored at a predetermined position in the stock yard.

The container carrier on the truck terminal side holds the stockyard container carried to the delivery point by the overhead traveling crane, travels to the truck terminal, and unloads the container onto the waiting truck. Then return to the stockyard again.

As described above, the gantry crane, the overhead traveling crane, and the container carrier grasp the container by themselves and transport the cargo, so that there is no need to match the timing with other steps in each process. The overhead traveling crane does not need to wait for the container carrier to arrive at the delivery point, so that the unloading operation can be performed efficiently. In the container terminal having the above configuration, when loading containers from a truck to a ship, the procedure described above may be reversed, and in this case, the loading operation can be performed efficiently.

Further, if at least two overhead traveling cranes are provided in each row of the stock yard as required, the container terminal of the present invention can be operated by the overhead traveling cranes other than those during loading and unloading. Can be transshipped, further improving the efficiency of cargo handling work.Also, if the container carrier is run on an elevated track and the truck is run on the lower lane, traffic between the container carrier and the truck will be eased Is done.

In each row of the stockyard 4 described above, two overhead traveling cranes 8, 8 are used in this embodiment.
Are guided by the traveling rail 8a so as to be movable in the direction of the gantry cranes 3, 3 and the truck terminal 5. The two overhead traveling cranes 8, 8
For example, while one is receiving the container P unloaded from the gantry crane 3 and transported by the container carrier 7, the other one reloads the container P stored in the stock yard 4, or While receiving the container P unloaded from the gantry crane 3 and transported by the container carrier 7, another one is provided to move the container P to the truck terminal 5.

Further, between the stock yard 4 and the truck terminal 5, for example, a container P delivery or receiving point in each row at the truck terminal side of the stock yard 4, and a receipt or delivery of the container P at the truck terminal 4 A orbital track 9 connecting the points is laid. The track 9 is, for example, an elevated track so that the truck T can travel thereunder. The inner track 9a and the outer track 9b are branched into four at the location of the track terminal 5, and the inner track 9a. And the four branches on the outer track 9b are gathered at the location of the truck terminal 5. A plurality of container carriers 10 are running on these tracks 9 respectively.

In the truck terminal 5, a truck T traveling below the track 9 travels through a traveling lane provided at the ground level of the quay 2 from the entrance gate G1 and enters the truck terminal 5, where it enters. Container P
And travel to the exit gate G2 in one way.

Next, a description will be given of, for example, an unloading operation procedure of the container P in the container terminal 1 having the above configuration. The container ship S stops on the quay 2, and the gantry cranes 3, 3 sequentially unload the container P to the apron 2a. At this time, the gantry cranes 3 and 3 sequentially unload the containers P toward the tracks 6 on which the containers P are not placed on the four tracks 6. Thereafter, the container carrier 7 sequentially travels on the track 6 to the delivery points of the gantry cranes 3, 3, and travels to the stockyard 4 while holding the container P.

The container carrier 7 has a stock yard 4
When traveling to, container placement information in each row of the plurality of stock yards 4 is received from a control room (not shown), and based on this information, the container yard 4 is moved to the stock yard 4 where the container P is not currently arranged. Inward orbit 6a
Alternatively, the vehicle travels after branching into the outer track 6b, and the container P is placed at the delivery point of the container P in the target row of the stockyard 4. Thereafter, the container carrier 7 travels to the gantry cranes 3 and 3 and repeats the above procedure.

In the stockyard 4 where the containers P unloaded from the gantry cranes 3 and 3 and transported by the container carrier 7 are placed, one overhead traveling crane 8 holds the container P and Repeat the work of placing in position.

On the other hand, another overhead traveling crane 8
Put the container P in the stock position on the truck terminal 5
To the side, the inner track 9a or the outer track 9b
Among them, the container P is placed on the track 9 where the container carrier 10 is not stopped, and this is repeated. The other overhead traveling crane 8 reloads the container P placed at the stock position so that the container P can move efficiently if necessary.

The container P moved to the track 9 on the truck terminal 5 side by the overhead traveling crane 8
Is held by the container carrier 10 that travels around. At this time, similarly to the above, the container carrier 10 receives the placement information of the container P in each row of the stockyard 4 from the control room (not shown), and based on this information, the inner track 9a or the outer track 9b. To the target stock yard 4 and receive the empty information of the four tracks 9 of the truck terminal 5, and based on this information, move the track to any of the target truck terminals 5. 9 and branch.

In the truck terminal 5, the truck T passing through the entrance gate G1 sequentially enters the empty track 9 among the four tracks 9 according to the arrival situation of the container carrier 10, and the container arrives here. Carrier 10
Unloads container P to truck T. Then, the truck T that has received the container P travels to the exit gate G2, and the container carrier 10 that has delivered the container P to the truck T goes to the stock yard 4 again.

As described above, the container P is unloaded or loaded from the container ship S to the container terminal 1 and from the container terminal 1 to the truck T.
Although omitted, the procedure for loading the container T from the truck T is the reverse of the above procedure. As described above, the container terminal 1 of the present invention includes the gantry crane 3,
Since cargo handling can be performed simultaneously and in parallel in each row of the container carrier 7, the stock yard 4, the container carrier 10, and the truck T, the time during which the flow of the container P stops at the delivery point of each container P is determined. Thus, the cargo handling work of the container P can be performed efficiently.

Further, the container terminal 1 of the present invention comprises:
Since the container carriers 7, 10 independently grab the container P from above and travel, the gantry cranes 3, 3,
There is no need to match the cargo handling speed (timing) of the overhead traveling crane 8, and the gantry cranes 3, 3 and the overhead traveling crane 8 do not need to wait for the container carriers 7, 10 to reach the delivery point, and as a result, Each process can be performed independently and in parallel, so that cargo handling can be performed efficiently.

It should be noted that the above embodiment is characterized in that
In addition, the aspect in which the configuration of claim 3 is added has been described. However, as a configuration corresponding to only claim 1, one overhead traveling crane 8 provided in each row of the stock yard 4 is provided.
Based on this, the container carrier 10 travels on a surface having the same height as the truck T. In this case, in each row of the stock yard 4, one of the containers P transfers the container P from the container carrier 7, and the other transfers the container P to the truck terminal 5 side or the container P at the stock position. You can't transpose P,
If this operation is performed alternately in each row of the plurality of stockyards 4, the same operation as in the above embodiment can be performed without lowering the cargo handling efficiency of the container P. Although the traffic to and from the truck T is complicated, the efficiency of the cargo handling work is not reduced.

As a modification of the container terminal 1, the overhead traveling crane 8 is naturally connected to the stockyard 4.
Or more may be arranged in each row, and by increasing the number of gantry cranes 3, tracks 6, tracks 9, etc., a greater amount of containers P can be unloaded and loaded more efficiently. Or you can.
