Are arranged on the front and rear sides of each container transfer chamber 11, and are partitioned into a large number of container storage chambers 12 which are arranged side by side in the left-right direction and stacked vertically. Each container storage room 12 is configured so that one container C can be placed and stored. Each container transfer room 11 is communicated with container storage rooms 12 on both sides thereof, and these container storage rooms 1 are connected to each other.
It is possible to arbitrarily transfer the container C between 2. Note that there are various types of containers C (generally, 40 footers (40 feet) according to the ISO standard).
ft container) and 20 footers (20 ft container) are frequently used, but in this example, the container storage area 1
Are made large enough to store containers of the maximum format, so that containers of all types can be stored for general purpose use. Of course, the container storage area 1 can also be constituted by a plurality of types of container storage groups for exclusively storing containers of a specific format.

As shown in FIGS. 1 and 3, the first bogie circulation path 2 is provided horizontally above and adjacent to the front portion of the container storage area 1, and has a pair of first and second front and rear extending left and right directions. The horizontal traveling paths 20, 20, a pair of front and rear second horizontal traveling paths 21, 21 located immediately behind and extending in the left-right direction are connected to the left and right ends of these horizontal traveling paths 20, 20, 21, 21. It is provided with a pair of right and left bogie transfer mechanisms 22, 22 so that a plurality of container mounting bogies 3 can circulate in a certain direction (the direction of the arrow).

Of course, each carriage moving mechanism 22 is configured as a horizontal traveling path on which the carriage 3 can smoothly travel and move between the first horizontal traveling paths 20 and 20 and the second horizontal traveling paths 21 and 21. Is also good. Each of the container mounting carts 3 is a self-propelled type having an upper surface formed on a mounting surface on which the container C is mounted, and a control signal from a container management control device (not shown) installed in the container terminal. The start / stop control is performed separately for each.

As shown in FIGS. 1 and 2, each container crane 4 includes a gantry 41 installed on a quay 40 and a gantry 41.
Guide rail member 4 that extends horizontally in the front-rear direction
2 and first and second cargo handling devices 43 and 44 and a container delivery device 45 provided on the traversing guide rail member 42.

As shown in FIG. 2, the traversing guide rail member 42 includes a girder 42a fixed to the upper end of the gantry 41 and a boom 42 pivotally connected 42c to the front end of the girder 42a.
b, and a series of traveling guide rails 42d extending in the front-rear direction is formed. The rear end portion of the girder 42a projects from the gantry 41 onto the first horizontal traveling paths 20,20. The front end side portion of the boom 42b projects over the container ship S.

As shown in FIGS. 2 and 4, the first cargo handling device 43 includes a traveling guide rail 4 of the traversing guide rail member 42.
A traveling body 46 movably supported by 2d;
And a first spreader 48, which is a container hanging tool suspended and supported via a wire rope 47 so as to be movable up and down, so as to be able to arbitrarily traverse a predetermined traversing path parallel to the traveling guide rail 42d. It is configured. Thus,
The first spreader 48 is capable of engaging and disengaging the four corner upper surfaces of the container C and transporting the container C in a suspended manner, similarly to the known spreader. When the maximum amount of containers C is loaded on the container ship S, the container C can be suspended and transferred without interfering with the upper surface of the container group C. Can be raised and lowered over the lowest position where the lowest container C stored in the lowermost position can be lifted.

As shown in FIGS. 2 and 4, the second cargo handling device 44 has a traveling body 49 supported on a guide rail 42d so as to be freely movable, and a vertically movable telescopic cylinder 50 which suspends and suspends the traveling body 49. And a second spreader 51 which is a supported container hanging tool, and on the land side (rear side) from the first cargo handling device 43, the first cargo handling device 43
It is configured to be able to traverse independently of. Thus, the second spreader 51 has the same structure as the first spreader 48, and the vertical position of the first spreader 48 coincides with the highest position of the first spreader 48 in the vertical direction by operating the cylinder 50 up and down. Ascending position (solid line position in FIG. 2) and first horizontal traveling path 20 which is a land-side container loading / unloading entrance
It can be raised and lowered over the lowest position (the position of the chain line in FIG. 2, the position in FIG. 3) at which the container C can be transferred to the upper carriage 3.

The container delivery device 45 is disposed between the first cargo handling device 43 and the second cargo handling device 44 as shown in FIGS. 2 and 4, and is supported by the guide rail 42d so as to be able to travel back and forth. Body 52, a telescopic frame 53 vertically suspended on the traveling body 52, and a container delivery body 54 provided at the lower end of the telescopic frame 53. It is configured to traverse following one cargo handling device 6.

That is, the traveling body 52 is composed of the traveling bodies 46, 4
9 does not include self-propelling means, and is connected to the traveling body 46 via traveling body coupling means (not shown) such as a cylinder. It is to be followed. The traveling body connecting means has a front-rear extension portion such as a cylinder, and has a relative positional relationship between the traveling bodies 46 and 52 in the front-rear direction (the traveling bodies 46 and 52).
52 relative intervals) can be changed within a certain range. In the cargo handling operation, the front and rear telescopic portions of the traveling body connecting means are usually in the closest state in which both traveling bodies 46 and 52 can carry out container delivery between the spreader 48 and the container delivery body 54 as described later (see FIG. 4)
So that it is minimized. Therefore, the container delivery device 45 travels in the same direction and the same amount as the first cargo handling device 43 with the traversing of the first cargo handling device 43 through the traveling body 52 and the traveling body coupling means simultaneously or with a slight time lag. It is sighing.

The telescopic frame 53 is moved by a suitable telescopic operation mechanism (not shown) such as a cylinder.
The uppermost position (FIG. 2) in which the upper surface of the container 4 is located at substantially the same height as the lower surface of the container C suspended from the cargo handling devices 43 and 44 at the highest position, and the lower surface of the container delivery body 54 It is configured to be able to ascend and descend over the nearest lowermost position (positions (I) and (J) in FIG. 6). Note that a container passage through which the container C can pass through the telescopic frame 53 in the front-rear direction is formed at the lower end portion of the telescopic frame 53 on the upper surface side of the container delivery body 54.

Further, the container delivery body 54 is constructed so as to be able to support the lower surface of the container C, and is made to protrude and retract from the telescopic frame 53 to the sea side (front side) and the land side (rear side). The container C can be transferred between the cargo handling devices 43 and 44 via the container passage of the telescopic frame 53. That is, the container delivery body 54 is immersed in the immersion position (the position (FIG. 4B)) immersed in the telescopic frame 53, and the first projecting position (the position (A) in FIG. 4A) that projects horizontally forward from the immersion position. The second projecting horizontally from the position to the rear
It is configured to extend and contract in the front-rear direction over the rush position (the position (C) in FIG. 3). Therefore, in a state where the container delivery device 45 is closest to the first cargo handling device 43, the container C is extended by extending the container delivery body 54 from the immersion position to the first projection position or the second projection position. It can be transferred between the first spreader 48 or the second spreader 51 and the container delivery body 54 (FIGS. 4A and 4C), and the container delivery body 54 supporting the container C is contracted to the first projecting position. Alternatively, the container C can be retracted from the elevating area of the first spreader 48 or the second spreader 51 by being immersed from the second protruding position to the immersion position, and stored in the container passage of the telescopic frame 53 to be on standby. (FIG. 7B). Further, the container delivery body 54 is moved up and down the telescopic frame 53 so that the container C can be transferred to and from the first or second spreader 48, 51 located at the highest position. 4 (position A in FIG. 6) and the lowest position (position I in FIG. 6) near the hold of the container ship S.

According to the container crane 4 configured as described above, the container ship S and the land-side loading / unloading area (the area above the container mounting trolley 3 located below the girder 42a).
And the cargo handling work between them can be performed efficiently.

That is, when unloading from the container ship S, the first cargo handling device 43 is _first traversed immediately above the container C ₁ to be unloaded, and the container delivery device 45 is moved to the first cargo handling device 43. Following this, the container C is traversed to a position closest to the container (solid line in FIG. 6A), and the first spreader 48 is lowered to suspend the container C (chain line in FIG. 6). At this time, the container delivery body 54 of the container delivery device 45 is immersed in an immersion position that does not hinder the lowering of the first spreader 48.

Then, the first spreader 48 is raised to raise the suspended container C ₁ to a height corresponding to the upper surface of the container delivery body 54, and then the container delivery body 54 is made to project to the first projecting position. Te, which in receiving the container C ₁ (FIG. 6 (B)). That is, when the first spreader 48 is detached from the container C ₁ (the twist lock pin is detached from the container C ₁ ), the container C ₁ is delivered from the first spreader 48 to the container delivery body 54.

Next, by immersion container delivery member 54 to the retracted position to leave the container C ₁ from the lifting area of the first spreader 48 (FIG. 6 (C) solid line), further a container delivery member 54 second projecting position It is projected to, and passes the container C ₁ in the second spreader 52 of the second handling unit 44 (FIG chain line).

[0022] Thereafter, the second spreader 51 which has received the container C ₁ from the container delivery member 54 is rampant rearward, placing the container located the container C ₁ on either one of the first horizontal runway 20 After being transferred to the placing trolley 3 (FIG. 3), the container traverses forward again, and
It returns to the position where the container can be received from.

By the way, although the second spreader 51 is ready to start delivering the container to the truck 3, the empty space is kept at the container receiving position on the first horizontal traveling path 20 immediately below the second spreader 51. If the cart 3 does not exist, or if the cart 3 that has previously received the container C exists at the container receiving position, it is necessary to stop the container delivery by the second spreader 51, and the container crane 4 Cargo handling efficiency is reduced. However, the bogies 3 are circulating on the first bogie circulation path 2, so that empty bogies 3 are sequentially supplied to the container receiving positions of the first horizontal travel path 20, and the containers C are received. The bogie 3 is immediately removed from the container receiving position and travels from the first horizontal traveling path 20 to the second horizontal traveling path 21. Therefore, a container receiving position exists on each of the pair of first horizontal traveling paths 20, 20, and the container receiving position can be arbitrarily selected, so that the container delivery from the spreader 51 to the bogie 3 can be performed quickly and without any loss time. Can be done smoothly,
The cargo handling efficiency by the container crane 4 is improved.

Further, since the first horizontal traveling path 20 is elevated above the container storage area 1 and the vertical distance between the cart 3 and the girder 42a on the first horizontal traveling path 20 is small, the container C ₁ enough extremely small lift amount of the second spreader 51 necessary pass the carriage 3, can be from the second spreader 51 to efficiently container delivery to cart 3. In addition, since the lifting and lowering operation of the second spreader 51 is performed by the cylinder 50 instead of the wire rope 47 like the first spreader 48, even if the second cargo handling device 44 is traversed at high speed, the container hanging支姿bias of the C ₁ does not become unstable,
It is not necessary to control the container posture (such as steadying of the container) as in the case of suspension with a wire rope.
As a result, the delivery of the container from the second spreader 51 to the carriage 3 can be performed more efficiently. The second
When performing vertical movement of the spreader 51 in the wire rope, in order to stabilize the transverse orientation of the container C ₁ (to avoid deflection of the container as much as possible), the second spreader 51
. However it is necessary to traverse in a state of being positioned in the uppermost position, if the lift amount of the second spreader 51 required for such as to, pass the container C ₁ as described above in carriage 3 Is very small, so that it is slightly inferior to the case where the cylinder 50 is used.
It is possible to efficiently transfer the container from the spreader 51 to the carriage 3. For this reason, in order to improve the efficiency of the cargo handling work, the second spreader 51 may be configured to move the second spreader 51 up and down by the wire rope in the same manner as the first cargo handling device 43 in order to raise the efficiency of the cargo handling. It will be understood that it must not.

On the other hand, the first spreader 48 of the first cargo handling device 43 descends when the container C ₁ is withdrawn from the elevation area of the first spreader 48 due to the immersion of the container delivery body 54 into the immersion position. to Tsu支the next container C ₂ located ₁ below (FIG. 6 (C) a chain line, Fig. (D)).
Subsequent, between the container transfer body 54, and similarly to the above, transfer of the container C ₂ is performed. The delivery of the container C ₂ from the first spreader 48 to the container delivery body 54 is performed until the second cargo handling device 44 received by the previous container C ₁ returns to the original position after delivering the container to the cart 3. Done between That is, the sea-side cargo handling work (including the container delivery to the container delivery body 54) by the first spreader 48 and the land-side cargo handling work (including the container delivery from the container delivery body 54) by the second spreader 51 are performed in parallel. Will be done. In addition, the first spreader 48 does not have to traverse to transfer the container to the second spreader 51, but simply moves up and down. (Decrease in cargo handling efficiency caused by the need to perform steadying) can be eliminated, and in combination with the above, cargo handling efficiency can be greatly improved.

When the unloading of containers C... Is not advanced downward as described above (following container C ₁ and unloading container C ₂ immediately below it), but is advanced in the front-rear direction. the second spreader 51 with the start the rampant rearward receiving the container C ₁ from the container delivery member 54, by transverse the first handling device 43 and container transfer device 45 to the rear (or front) , First
Subsequently the spreader 48 to the container C ₁ is positioned immediately level container C ₃ to be later load (FIG. 6 (E) solid line), which Tsu支the container C ₃ (FIG chain line). Subsequent, similarly as described above, passing the container C ₃ from the first spreader 48 to a second spreader 51 through the container delivery member 54, it is the further delivered to the carriage 3.

By the way, the container delivery from the first spreader 48 to the second spreader 51 via the container delivery body 54 is performed by raising and lowering the container delivery body 54 to minimize the amount of elevation of both spreaders 48, 51. It can be performed efficiently while suppressing it.

That is, as the unloading operation progresses, the upper surface position of the container group C on the container ship S decreases, and accordingly, when the container is transferred from the first spreader 48 to the container transfer body 54, The vertical position of the container delivery body 54 is also lowered. That is, the container delivery body 54 is lowered to a position as close as possible to containers C... Located immediately below ((FIG. 6 (F)),
Receive containers C ₄ from the first spreader 48 (FIG. (G) solid line). Then, after having immerses container delivery member 54 to the retracted position (FIG. 6 (G) a chain line), is raised to a position that may pass the container C ₄ to the second spreader 51 positioned in the uppermost position or a position close thereto ( FIG 6 (H) solid lines), is projected to the second protruding position, and passes the container C ₄ to the second spreader 51 (FIG chain line). By thus elevating the container delivery body 54, if the container C ₄ to be load later is in the low position of hatch near also, from the first spreader 48 second spreader 51
Each spreader 4 needed to deliver the container to
The amount of lifting and lowering of 8, 51 can be minimized. Needless to say, since the required amount of elevation of the second spreader 51 is small, the cylinder 50 having a small stroke can be employed as the elevation operation means.

[0029] Similarly, in the case of unloading a container C ₅ that is stored in艙内container ship S, while being lowered container transfer body 54 as much as possible, for example, a container transfer body 54艙In the state of being positioned near the mouth (FIG. 6 (I))
The container C ₅ on hands over from a first spreader 48 to the container transfer body 54 (FIG. (J) solid line), to raise the container delivery member 54, performs the containers pass to a second spreader 51 (FIG. ( J) by dashed line)
The amount of elevation of each of the spreaders 48 and 51 can be minimized.

The container delivery device 45 follows the first cargo handling device 43 and traverses, but the following is performed simultaneously as described above, or may be performed with a certain time difference depending on the cargo handling situation. For example, as shown in FIG. 7, when the unloading proceeds forward, when the container C ₆ is delivered from the first spreader 48 to the container delivery body 54 ((K) in FIG. 7), the first spreader 48 becomes traveling forward, positioned on the next container C _7, in the meantime, the container transfer member 54 is raised, performs containers pass to a second spreader 51 (FIG. (L)).
Thereafter, the container transfer member 54 is lowered together with the rampant forward, is positioned at a position of the container C ₇ may receive from a first spreader 48 (FIG. (M)). That is,
The container delivery device 45 follows the first cargo handling device 43 with a certain time difference. In addition, the following traversing is performed by extending and retracting the front and rear expansion and contraction portions of the traveling body connecting means that connects the two traveling bodies 46 and 52.

Therefore, by repeating such operations, the unloading cycle time can be greatly reduced, and the unloading operation can be performed extremely efficiently. The traveling connecting means for connecting the two traveling bodies 46 and 52 is configured to be detachable, and the second cargo handling device 43 and the container delivery device 45 may be connected to the rear end of the traversing guide rail member 42 as necessary. It is also possible to carry out cargo handling only with the first cargo handling device 43.

Further, the containers C are connected to each of the first horizontal traveling paths 2.
When loading the container ship S from the trolleys 3 on 0,
By performing the operation reverse to the unloading operation, the operation can be performed efficiently as described above.

As shown in FIGS. 1 and 3, the sea-side loading / unloading device 6 is a container delivery room 12 selected from among the container storage rooms 12 located at the top of the container storage area 1.

The plurality of first container transfer mechanisms 60 are installed in parallel with each other at positions inconsistent with the container cranes 4 and 4 in the left-right direction. The length in the front-rear direction of each guide rail 60a extends between the direction directly above the container storage chambers 12 where each traveling body 60b communicates with the foremost container transfer chamber 11 and the direction directly above the land side loading / unloading area described later. It is set so that it can run. The lower guide rail 60a is installed as close to the container storage area 1 as possible, and when the spreader 60c transfers the container to and from the truck 3 on the second horizontal traveling path 21, The spreader elevating amount required for the operation is minimized. The vertical distance between the guide rails 60a and 60a is such that the container C does not interfere with the lower traveling body 60b when the container C is suspended and transferred with the upper spreader 60c positioned at the highest position. Is set as small as possible. Each spreader 60c has the same structure as the spreaders 48 and 51.

The container delivery chambers 12a...
As shown in the figure, the container storage room is located on the traveling route of each spreader 60c, and the spreader 60c and the container C suspended from the spreader 60c can be inserted into and removed from the upper opening.

As shown in FIGS. 3 and 5, each of the second container transfer mechanisms 61 is a kind of stacker crane, and includes a crane body 61a installed in the container transfer chamber 11 so as to be able to travel in the left-right direction, and a crane body. The arm 61b is supported by the crane main body 61a so as to be able to move up and down and is capable of extending and contracting forward and backward, and the spreaders 48, 51,
60c having the same structure and function as those provided in the 60c, so that the container C can be suspended and transferred between any container storage room 12 and the container delivery room 12a. Is configured. That is, the arm 61b is extended onto the container C of the container storage room 12 (or the container delivery room 12a) (FIG. 5A), and the twist lock pins 61c are engaged with the container C (see FIG. B)), the arm 61b is reduced, and the container C is taken out of the container transfer chamber 11 in a suspended state ((C) in the same figure). Thereafter, the traveling of the crane main body 61 and the lifting and lowering of the arm 61b cause the suspension to be suspended. The transported container C is brought to a position directly opposite the container storage room 12 or the container delivery room 12a as a desired transfer destination, and the container C can be handled to the desired transfer destination by extending the arm 61b. Has become.

According to the sea-side loading / unloading device 6 configured as described above, each spreader 6 of each first container transfer mechanism 60 is provided.

1a, and by moving the arm 61b up and down and extended and contracted, the container delivery room 12a and the container storage room 12a are moved.
Can be passed to and from the container. Therefore, by repeatedly carrying out the container delivery by the two container transfer mechanisms 60, 61, the trucks 3 circulating between the first horizontal traveling paths 20, 20 and the second horizontal traveling paths 21, 21 and the container crane Via the containers 4 and 4, the unloading from the container ship S to the container storage room 12 or the loading from the container storage room 12 to the container ship S can be efficiently performed.

That is, when the container C unloaded from the container ship S is stored in the container storage room 12,
First, the trolley 3 receiving the container C from the second spreader 51 is caused to travel from the first horizontal travel path 20 to one of the second horizontal travel paths 21. Thereafter, the carriage 3 is stopped when it is located below the spreader traveling path of the first container transfer mechanism 60. Next, this stop truck 3
