Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to the unloading of containers from a container ship on the container quay, the loading of the containers on the container ship, and the carrying out of those containers from a container stacking yard by a chassis. In addition, the present invention relates to a container loading / unloading method when the chassis is loaded into a container stacking yard.

[Prior Art] As described above, there are roughly three types of methods conventionally used for container loading and unloading using a container ship, a container stacking yard, and a chassis.

One such method is the full chassis method, which uses a gantry crane to unload containers on a container ship and a trailer-type chassis.This method allows the trailer-type chassis to be moved from anywhere at any time, which is the most flexible method. Although it is a method with good operability, it has the drawback of inefficient use of the yard because it requires the largest yard area.

The next method is the gantry crane, transfer crane, and transfer crane method that uses a chassis, which has the advantage that the yard area used is the smallest, but in this case, compared to the full chassis method. It has the drawback of lacking flexibility.

Further, the third method, the straddle carrier method,
A gantry crane and straddle carrier are used, and both flexibility and required yard area have advantages and disadvantages between those two methods.

[Object of the Invention]

The present invention has been made in order to solve the above-mentioned conventional drawbacks, and while maintaining almost 100% flexibility as a cargo handling system, it is possible to obtain a yard use efficiency that is substantially the same as that of a transfer crane. The purpose is to provide a container handling method.

[Structure of Invention]

In order to achieve the above object, the container loading / unloading method of the present invention uses a container stand that can be placed on the upper part and can be moved to any position by a stand carrier having a function of raising and lowering the container stand as an intermediate joint. It is characterized by loading and unloading containers.

Is being carried.

Next, a cargo handling flow in which the container cargo handling method of the present invention is applied to the cargo handling equipment shown in FIG. 1 will be described. First, when the container ship 1 is unloaded, the container is unloaded by the port crane 2.
The container is placed on the container stand 4 which is set under the port crane 2 in advance, and then the stand carrier 6 carries the container stand 4 loaded with the containers to the delivery lane 7 or 11.

However, when the yard crane 5 is carrying out other cargo handling, it is transported to the container stand yard 14 and temporarily placed,
When the yard crane 5 becomes usable, it is transported from the container stand storage area 14 to the delivery lane 7 or 11.

Next, the yard crane 35 hoists the container placed on the container stand 4 placed on the stand carrier 6 and stacks it on the container stacking area 9 or 10.

In this case, if the matching with the yard crane 5 cannot be achieved, only the stand carrier 6 is used for the container stand 4
Depart from and return to port crane 2 or container stand yard 14.

Also, when loading the container into the container ship 1, the yard crane 5 moves the container stacking area 9
Alternatively, 10 containers are lifted, and the containers are placed on the container stand 4 which is set in the delivery lane 7 or 11 in advance.

Next, the stand carrier 6 conveys the container on the container stand 4 from the transfer lane 7 or 11 to the lower part of the port crane 2. At that time, if the port crane 2 has not completed the previous work, the container carrier is placed in the container stand yard 14. Temporarily place, and the stand carrier 6 immediately holds the transfer lane 7 with another container stand 4 on which no container is placed.
Or return to 11.

Here, when the position is determined under the port crane 2,
Temporary placement is done not under the container stand yard 14, but under the port crane 2.

Therefore, the port crane 2 lifts the container from the container stand 4 on which the container is placed, loads it on the container ship 1, and loads it.

Next, when receiving the container into the container handling facility, the external chassis 20 gated in from the gate 16 stops beside the transshipment lane 15, and the container 21 is moved in advance by the transfer crane 24 as shown in FIG. It is transshipped to the container stand 4 set in the transshipment lane 15.

In addition, the cycle time of the receiving work at this time is
It can be within 50 seconds.

Therefore, the outside chassis 20 is gated out as it is, and the container stand 4 loaded with the containers 21 is transported to the delivery lane 8 or 12 by the stand carrier 6, but at this time, the yard crane 5 performs other work. If there is, it is temporarily placed in the container stand yard 13 and transported to the delivery lane 8 or 12 after the yard crane 5 becomes usable.

The yard crane 5 lifts the container 21 on the container stand 4 moved by the stand carrier 6 and stacks it on the container stacking area 9 or 10.

Here, when the matching with the yard crane 5 cannot be achieved, the stand carrier 6 is detached from the container stand 4, and immediately returns to the container stand yard 13 or the transshipment lane 15.

Further, at the time of delivering the container from the container loading / unloading facility, the reserved container is loaded onto the container stand 4 by the transfer lane 8 or 12 in which the reserved container is preliminarily suspended from the container stacking area 9 or 10 by the yard crane 5. 6 is transported to the transshipment lane 15 or the container stand yard 13.

Therefore, the gated-in foreign chassis 20 is stopped in the transshipment lane 15, and the container 21 in the transshipment lane 15 is immediately loaded into the chassis 20 by the transfer crane 24 as shown in FIG.

Here, the container in the container stand storage area 13 is
At the same time when the chassis 20 is gated in, it is transported to the transshipment lane 15 by the stand carrier 6 and transferred to the transfer crane.
The chassis 20 is delivered to the chassis 20 by 24, and the chassis 20 is immediately gated out.

On the other hand, containers without reservations are loaded into the container stand 4 by the transfer lane 8 or 12 by the yard crane 5 from the container stacking area 9 or 10 after the gate-in of the foreign chassis 20, and transported to the transshipment lane 15 by the stand carrier 6. Then, it is delivered to the chassis 20 by the transfer crane 24.

Here, if it takes time for the container to be transported to the transshipment lane 15, the chassis 20 is temporarily
We shall wait at 18.

〔The invention's effect〕
