[0002]

2. Description of the Related Art FIG. 17 is a side view of a conventional cargo handling facility of a container terminal. The containers 13 loaded on the container ship 7 are unloaded by the quay container crane 8, placed on the container conveyor 11, and sent to the land side. At the land-side end, the container 13 is lifted by the yard bridge crane 9 and is loaded on the chassis (trailer) 14 or is loaded on the container yard 10. In addition,
12 is a quay.

The containers 13 stacked by the yard bridge crane 9 are sequentially transported outside from the container terminal. At this time, there is no problem if the containers 13 stacked on the upper side are sequentially transported, but if the containers 13 stacked on the lower side are to be shipped first, remove the container on the upper side. Therefore, it has to be shipped, which takes time and troubles the smoothness of the cargo handling work.
In order to solve such a problem, it has been studied to arrange storage shelves in which storage cells for storing containers one by one are formed in multiple stages so that the container 13 can be taken out from any storage cell when shipping. The present applicant has filed a patent application (Japanese Patent Application No. 8-69634 (not disclosed)) for a stack crane used in such a container terminal.

Accordingly, not only a large space is required outside the storage building 6, but also a large burden is imposed on costs such as a foundation work for erecting a gantry. In addition, the elevated track 5 on which the truck 4 travels is congested, which is very difficult to control. Since the elevated track 5 passes through the storage building 6, the container storage cell 2 must be removed to form the passage 2i. Min storage capacity is reduced.

The present invention has been made in view of the above-mentioned problems of the prior art. By providing a truck passage along the sea side of a storage building, it is possible to save space in a container yard and store containers.

Others are the same as the first invention. By using a semi-port crane, the number of cranes can be reduced. Further, since both sides of the extended portion of the traverser traversing rail on the sea side of the storage building can be used as a temporary storage space for containers, it can be used as a buffer area.

As described above, in both the first invention and the second invention of the present application, the truck traveling rail is provided along the sea side surface of the storage building, and the truck can be traversed by providing a route change rail. This saves space in the container yard. Since there is no trolley aisle in the storage building, the capacity of the container storage building can be increased. In addition, the handling efficiency of the container can be increased by simplifying the cargo handling of the container. . Also, an overhead crane or a semi-portion crane that transfers containers from the trolley to the traverser is provided, and the stack crane is dedicated to storing containers received from the traverser in container storage shelves. Therefore, the speed of container handling can be increased.

A container is exchanged between 0 and the overhead crane 29.
The overhead crane 29 is the container 1 received from the cart 20.
3 is transferred to the traverser 40 waiting outside the storage building 6. The traverser 40 traverses in the storage building 6 and delivers the container 13 to the stack crane 3 waiting at the target container storage shelf 2. The stack crane 3 stores the received container 13 in the container storage shelf 2.

When shipping the container 13, the stack crane 3 places the container taken out of the container storage shelf 2 on the traverser 40. The traverser 40 traverses and transports the container 13 to outside the land side surface 6c.
The container 13 on the traverser 40 is lifted by the overhead crane 29 above the extended portion of the traverser traversing rail 41, and the container 13 is loaded on the chassis 14 waiting near the traverser 40 and shipped.

The half-port crane 50 is used in place of the eight overhead cranes 29 traversing on the fixed rail 28 used in the first invention, and has a trolley 50a traversing on a half-port garter. Then, the container 13 is lifted from the cart 20 traveling on the building-side rail 21b and transferred to the traverser 40. The semi-portable crane 50 is a traveling rail 51 laid directly on the seaside side surface 6b of the storage building 6.
a is mounted on one side wheel, and the other side wheel is mounted on a traveling rail 51b laid on a gantry 26 supporting the carriage traveling rail 21 to travel. The second invention is the same as the first invention except for the above.

The advantages of the second invention over the first invention are that the number of cranes for transferring the container 13 between the truck 20 and the traverser 40 is small, and that the traverser traverse rail 41 moves out of the storage building 6. A space 52 for temporarily storing the container 13 can be provided on both sides of the extended portion of the above, so that it can be used as a buffer area. Therefore, it is possible to avoid a drop in the cargo handling efficiency even when there is a temporary failure in some of the cargo handling machines or when there is an imbalance in the cargo handling capacity.

The present invention is not limited to the embodiment described above, and various changes can be made without departing from the gist of the invention. For example, the bogie traveling rail 21 has been described as an elevated type, but may be a ground type.

[0036]

As described above, the container tar of the present invention is used.
Minal is provided with a trolley running rail along the sea side surface of the storage building so that the trolley circulates and the trolley passage is not provided in the container storage building, so that the container storage capacity can be increased. Traversers are mainly used to traverse containers inside the storage building, and stack cranes can concentrate on storing containers received from traversers in container storage shelves. Has an effect. Furthermore, in the second invention of the present application, the container is transferred between the trolley and the traverser by using the semi-portable crane traveling along the seaside side surface of the storage building. There is an effect that spaces for temporary storage of containers can be provided on both sides of the extended portion to be used as a buffer area.
