Abstract

PROBLEM TO BE SOLVED: To reduce the whole cost and simultaneously perform warehousing and shipping by each crane by dividing a container storage place into an area for import and an area for export, performing a handling for the former by a high-rise storage device and performing the handling for the latter by a stack storage device. SOLUTION: A container high-rise storage device 50 and a container stack storage device 60 are provided in parallel along a quay wall 12. When an import container 13 is stored in the storage shelf of the container high-rise storage device 50 from a container ship 7, the storage is performed by a container crane 8, a sea side transfer crane 46 and a stack crane 3, etc. When an export container 13 is stored in the container stack storage device 60 from a chassis 14, a stack is performed by an overhead crane 45 on a land side and an overhead crane 45, etc., at the middle location. Thus, the whole cost is reduced by using the container high-rise storage device 50 which is capable of performing an arbitrary take-out for the import container 13 and by using an inexpensive container stack storage device 60 for the export container 13.

In the container terminal described above, handling of the container is smooth, and
Although highly efficient, the storage building 6 and the stack crane 3 for storing the containers 13 in three dimensions are expensive. Although the three-dimensional storage of the import container 13 is extremely advantageous for the subsequent handling, the export container 13 is often not necessarily three-dimensionally stored and may be stacked. That is, for the export container 13, 1)
By container size (20 ft or 40 ft, etc.) 2)

When storing imported containers from a container ship in storage shelves of a container storage device, the trucks are circulated on a truck traveling rail consisting of a sea side rail, a building side rail, and a rail for changing a route, and the truck is placed on a sea side rail. The container is exchanged between the truck and the container crane, and the container is exchanged between the truck and the sea-side transfer crane on the building-side rail. The sea-side transfer crane places the container received from the trolley on a traverser waiting outside the storage building. The traverser lands on the land side and hands over the container to a stack crane waiting at the desired storage shelf. The stack crane stores the containers received from the traversers on storage shelves.

When an import container is shipped from the container three-dimensional storage apparatus by the chassis, the sea-side stack crane places the container taken out of the storage shelf on the traverser. The traverser travels outside the land side of the storage building and delivers the container to the waiting land transfer cranes there. The land transfer crane loads the container received from the traverser into the chassis.

When storing the export container from the chassis in the container stacking storage device, the land-side overhead crane stands by at the crane traverse rail land-side overhang, and the intermediate overhead crane is at the position where the container is to be stacked. Waiting at. The container is lifted from the chassis by the overhead crane on the land side, then slightly traverses to the land side, and the container is placed on the traverser that has moved under the overhead crane. The traverser traverses to the sea side and reaches below an intermediate overhead crane. The container on the traverser is lifted by an intermediate overhead crane, and after the traverser moves, it is suspended and stacked. Export containers are classified by container size.
Sorting by type of cargo, container ship, destination port, and weight, and stacking for each sorted lot.

The seaside overhead crane is waiting near the seaside overhang of the frame. The stacked containers are lifted by an intermediate overhead crane. Placing the container on a traverser that has moved under the middle overhead crane, the traverser traverses to the ocean side and reaches below the ocean side overhead crane.
The container is lifted from the traverser by the sea-side overhead crane, traverses slightly to the sea side, and is hung down to place the container on the trolley on the building-side rail. The trolley circulates and moves on the rails on the sea side, and the container on the trolley is lifted by the container crane and loaded on the container ship. The container three-dimensional storage device is provided with sea-side and land-side transfer cranes, and two stack cranes are provided in each lane. The container stacking storage device is provided with four overhead cranes in each lane. Both devices can simultaneously perform the loading and unloading operations. If a chassis passage is also provided on the sea side, when there is no container ship, it is possible to unload from both the land side and the sea side.

The overhead crane has a trolley that moves in the longitudinal direction of the container to be unloaded, so that two rows of stacked containers can be unloaded. Therefore, the number of overhead cranes can be halved, and when lots are managed and stacked, the area where stacking can be performed is expanded, which facilitates management. Also,
Since traversers are provided for each row of stacked containers, containers can be transported between any intermediate overhead crane and the ocean side or land side overhead crane when entering and exiting at the same time. .

As described above, a three-dimensional container storage device that can be arbitrarily taken out for an import container and an inexpensive container stacking storage device for an export container are used, and these are arranged in parallel. There is an effect that the cost of the entire container terminal can be reduced without impairing smoothness and high efficiency. Further, since the lateral movement of the container in the storage device is almost performed by the traverser, the speed and efficiency of the container handling can be improved. Further, when the container work is congested, it is possible to simultaneously perform the incoming work and the outgoing work in each lane.
