Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a storage facility for a container that stores a plurality of containers in a stacked state.

[Prior Art] Containers used for marine transportation are stored and left in warehouses near the harbor and outdoors, but the amount is increasing due to the increase in size of ships and the increase in cargo volume. In addition, a huge amount of labor is required to store empty containers.

Conventionally, when this container is stored, since the containers are formed in a rectangular parallelepiped box shape, they are arranged in a stacked state, and a forklift or the like is used.
It is designed to be stacked in steps or 4 steps.

[Problems to be solved by the invention] However, in order to prevent falls due to typhoons, earthquakes, gusts, etc., it is necessary to suppress the number of stacked containers to the above-mentioned number of stages, and between containers, there is storage and retrieval. It was necessary to open a passage for moving the forklift at that time, and the storage site area tended to increase.

In particular, there are containers having sizes different from 20 feet and 40 feet in length, and it has been desired to efficiently store these.

An object of the present invention is to provide a storage facility capable of storing a plurality of types of containers so as not to restrict the reduction of the storage site area by increasing the number of stacked containers.

[Means for Solving the Problems] In the present invention, a container storage zone for stacking containers in multiple stages in the height direction is defined by a container guide column that guides and supports a side edge line along the height direction of the container.
While arranging these container storage zones in a matrix in a horizontal plane, in a container storage facility for loading and unloading containers into and from any container storage zone by cargo handling means moving in a horizontal plane above each container storage zone, An intermediate container guide having a T-shaped cross-section outside and adjacent to the container storage zone is provided between a pair of container guide columns facing each other in the longitudinal direction of the container among the container guide columns forming the container storage zone. The guide rollers at four corners of the spreader for a container, which are arranged so as to face each other and move up and down in the container storage zone, are configured to be expandable and contractable.

[Operation] The container guide column defines a container storage zone for a container having a specific length dimension, for example, a container having a length of 40 feet. When a 40-foot container is loaded into this container storage zone, the intermediate container guide column is located adjacent to the outside of this container storage zone, so that there is no obstacle to the cargo handling.

On the other hand, in the case where a container having a short length, for example, a container having a length of 20 feet is loaded into one half of the container storage zone, two of the four corners of the spreader are located at a distance from the intermediate container guide column. Although it becomes far away, the guide roller of the spreader is expandable and contractable, so that the guide roller is in contact with the intermediate container guide column and guides it stably.

Therefore, two kinds of containers can be surely stored in a stacked state by using one or half of the container storage zones as needed.

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

First, the outline of the container storage facility will be described with reference to FIGS. 2 to 5.

In FIG. 2, the container storage facility 100 has a frame structure 3 in which vertical frames 8 made of H-shaped steel and horizontal frames 9 are arranged in a grid pattern.
Also extends in the direction perpendicular to the paper surface. Below, storage facility 100
Width direction is X direction, depth direction is Y direction, and height direction is Z direction
Called direction.

First, four container guide pillars 1 made of steel with an L-shaped cross section for guiding and supporting the side ridges along the height direction of the container A are parallel to each other at intervals corresponding to the four corners of the container A. A container storage zone 2 for stacking and storing the containers A is vertically formed between these four container guide columns 1. And
Two of these container storage zones 2 are used as a frame structure 3
Surrounded by four vertical frames 8. By adding this as a unit, a plurality of sets of four container guide pillars 1 are arranged next to each other, and each set of container guide pillars 1
The container storage zone 2 formed between the
They are arranged in a matrix (2 rows and 28 columns in the illustrated example) in the plane. Each container guide pillar 1 is erected on the ground 5 at a height such that the containers A can be stacked in the storage zone 2 from the ground 5 by, for example, 10 steps.

At the top of the frame structure 3, two overhead traveling cranes 4 as cargo handling means are mounted so as to be able to travel in the space above the container storage zone 2. In addition, at two locations in the middle of the frame structure 3 in the row direction (X direction), the lower part of the container storage zone 2 (in the illustrated example, two rows of three rows and two columns) is used, and the container delivery port 6 is provided. Are formed along the rows. A container suspension passage 7 for lifting and lowering the container A is formed above both container delivery ports 6.

On the other hand, the frame structure 3 is used in the container storage zone 2
It is composed of a plurality of vertical frames 8 standing upright outside both ends of the row (Y direction), and a horizontal frame 9 connecting the vertical frames 8. Each vertical frame 8 is made of H-shaped steel and is formed to be longer than the container guide column 1 and protrudes substantially upward by one container A. At the upper end thereof, these are arranged in rows of the container storage zones 2 (X direction). ) A pair of rails 11 are connected along
(FIG. 3) are provided.

As shown in FIG. 3, the overhead traveling crane 4 is spanned by the two rails 11 and is movable in the X direction. A girder 12 is bridged between the rails 11. The trolley 14 for hoisting the container gripping spreader 13 is provided so as to be capable of reciprocating in the length direction of the girder 12, that is, the Y direction, and reciprocates in a horizontal transport path 15 formed by a horizontal frame 9 above the container storage zone 2. It is designed to run. Above overhead traveling crane 4
Can travel on the rail 11 and carry one container A in response to a command from the operation room 17 provided at the delivery port 6.

Returning to FIG. 2, the storage facility 100 is devised so as to store two types of containers. The first type of container of interest here is container A, which in this example is 40 feet long. As described above, the storage facility 100 can store 10 containers A of 40 feet in a stack in the height direction, that is, in the Z direction, 28 in the X direction and 2 in the Y direction. it can. The second is a 20-foot container C that is exactly half the length of this container A, and the storage facility 100 is
Two 20-foot containers C can be stored in the container storage area of the container A two by two.

As will be described in detail, as can be seen from FIG. 4, first, the four container guide pillars 1 that form the container storage zones 2 one by one are arranged at intervals of the four corners of the container A having a length of 40 feet. Correspondingly set up. Each container guide pillar 1 is made of a steel material having an L-shaped cross section, and its guide surface 1a (first
4) in the vertical direction of container A, that is, in the Y direction.
A 40-foot container A can be stacked and accommodated by guiding and supporting the vicinity of the four corner ridges formed by the surface. The upper ends of the four container guide columns 1 are flared so as to easily receive the container A (not shown).

Next, as shown in FIG. 1, two 20-foot containers C are provided at an intermediate position between the pair of container guide pillars 1 and 1 facing each other in the Y direction among the above four container guide pillars 1. An intermediate container guide column 10 having a T-shaped cross section is erected so as to be partitioned into the storage space. To be precise, the intermediate container guide pillar 10 is arranged outside the container storage zone 2 and adjacent to it, with the T-shaped central walls 10a of the intermediate container guide pillars 10 facing each other. ing. Thereby, a container storage zone for a 20-foot container is formed between both sides of the central wall 10a having a T-shaped cross section and the container guide column 1.

On the other hand, two types of spreaders 13 are prepared which are compatible with the above two types of containers A and C. However, the problem here is that the intermediate container guide column 10 is positioned outside the boundary line of the container storage zone 2 so as not to interfere with the loading and unloading of the container A. That is, when loading a short container C,
The guide surfaces 10b on both sides of the T-shaped central wall 10a of the intermediate container guide pillar 10 are farther than the distances to the L-shaped corners of the container guide pillar 1 when viewed from the four corners of the container C. Is.

Therefore, the spreader for this equipment is shown in Fig. 1 (b).
As suggested in (c), the guide rollers 131 provided at the four corners of the guide roller 131 are configured to be expandable and contractible.

Specifically, as shown in FIGS. 6 and 7, the base of the rotating shaft 133 is rotated around the axis by bearings 132 composed of a seat 132a and a restraining lid 132b at the four corners of the top and bottom of the spreader 13. A cylinder 134 that supports the arm 135 of the guide roller 131 to be expandable and contractible is attached to the tip end of the rotary shaft 133. Then, a pinion 137 is provided on the trunk of the rotating shaft 133 so as to surround it, and the pinion 137 is
It is meshed with a rack 138 which is extensible and supported by a fixed cylinder 139 on the upper surface of the spreader 13.
The roller 136 of the guide roller 131 is pivotally supported by the shaft 136a at the tip of the arm 135, as shown in FIG.

With the above configuration, the guide rollers 131 provided at the four corners of the spreader 13 can freely expand and contract and rotate according to the distance to the other party.

Addresses are assigned to the storage locations of the above-mentioned containers A and C, and they are managed by the computer in the operation room 17. When the container A or C is put in and the stored container A or C is put out, the address of the corresponding storage place is designated.

When storing a 40-foot container A as shown in FIG. 1 (a), the intermediate container guide pillar 10 does not interfere with anything, so that the original four container guide pillars 1 can be used to store the 40-foot container. A can be guided and stored. That is, the carrier B traveling on the ground 5
By the spreader 13 of the crane 4, the container A transported by is lifted in the suspension passage 7 of the container A above the frame structure 3, that is, to the highest position in the Z direction. The crane 4 is then moved in the X direction. Since each crane 4 has a trolley 14 movable in the Y direction,
The container A is moved in the space 15 in the X and Y directions. After that, the crane 4 is stopped at the designated address,
Only the container A is suspended downward in the Z direction by the spreader 13. When the container A is taken out, the container A is hung by the overhead crane 4 from above the address and conveyed to the container delivery port 6.

On the other hand, as shown in FIG. 1 (b), when loading a 20-foot container C into the area on one side of the container storage zone 2, the spreader 13 for holding the container is contracted to 2
Length for container C of 0 feet. Then, at a predetermined address, the spreader 13 is slightly moved to the container guide pillar 1 side to be hung or lifted for cargo handling. At this time, the ridgelines on both sides of the surface on the opposite side of the container C are slightly separated from the intermediate container guide column 10, but the guide roller 131 is expandable and rotatable, so that the T-shaped intermediate container guide column is formed. 10 guideways 1
0b will be guided while appropriately abutting. Therefore, the guide rollers 131 of the spreader 13 are guided along the container guide pillar 1 or the intermediate container guide pillar 10 at all four corners.

As shown in FIG. 1 (c), the case of loading a 20-foot container C into the other half of the container storage zone 2 is similar to the case of the above-mentioned 1 (b), and the spreader 1
When loading and unloading 3 toward the container guide pillar 1 side, the guide roller 131 expands and contracts and rotates to properly contact the guide surface 10b of the T-shaped intermediate container guide pillar 10, and is stably guided at all four corners.

Thus, two types of containers can be appropriately stored and taken out in the same size as the storage facility having the single type of container storage zone 2. When the container A or C is moved up and down in the container suspension passage 7 and the container storage zone 2 during the loading and unloading operations of the container A or C, the guide surface 1 of the container guide pillar 1
a or the guide surface 10a of the intermediate container guide pillar 10 with this
By supporting the vicinity of the four ridge lines in the height direction of the container A or C, the shake in the left and right directions can be restricted. Therefore, stable cargo handling work can be performed. Further, even when the containers A or C are stacked in the container storage zone 2, the container guide pillar 1 or the intermediate container guide pillar 10 can surely prevent the collapse of the load, etc. You can do a lot.

[Effects of the Invention] As described above, according to the present invention, two types of containers having different lengths can be stored by filling the container storage zone or using half of the storage zones as needed. The range of utilization of container storage facilities can be expanded. Further, even when the container is loaded / unloaded in the half of the container storage zone, the vertical four surfaces (corners) of the container are guided and supported so that the left and right shakes are restricted.
