Description

  The present invention relates to a technology for transferring a container to a chassis, and more particularly to a technology capable of efficiently transferring a container to a chassis without any delay.

  A typical example of a vehicle that is used to carry a container into a container storage shelf formed by three-dimensionally collecting shelves capable of storing the container, and to carry out the container from the container storage shelf, and a chassis on which the container can be mounted, And a trailer head that pulls (Patent Document 1). In such a vehicle, storage and management of a non-container-mounted chassis (hereinafter, sometimes referred to as an empty chassis) that remains after the container is brought in becomes a problem. For example, if an empty chassis is left unattended or placed in a container terminal, it may cause traffic congestion and accidents, reducing the soundness and efficiency of the operation of the entire terminal.

  Regarding storage and management of empty cargo chassis, a container chassis storage device has been proposed in which container storage shelves capable of storing empty cargo chassis are three-dimensionally gathered (Patent Document 2). According to this apparatus, a large number of empty chassis are gathered in one place, stored and managed, and removed from the designated shelf when the empty chassis is required, so at least the above-described problems are unlikely to occur. .

In order to make the container storage shelf function more effectively, it is conceivable that the chassis storage shelf is provided alongside the container storage shelf. However, when the container storage shelf and the chassis storage shelf are provided side by side, the container storage shelf is unloaded from the container storage shelf. It is required separately that the container to be transferred can be smoothly transferred to the chassis unloaded from the chassis storage shelf.
If smooth transfer is not possible, it will be difficult to organize the logistics, which may lead to a decrease in container transport efficiency.
For example, even if the container and the chassis can be removed from the container storage shelf and the chassis storage shelf in a timely manner, if one of the chassis and the container has not arrived at the transfer location in a timely manner, the container is transferred to the chassis. The loading does not proceed, the other is forced to wait and becomes in a traffic jam. For example, when the arrival of the container is delayed, the chassis that is waiting to mount the container and the trailer head that is waiting to pull the container are congested. When the arrival of the chassis is delayed, the carrying out of the container is delayed, and the trailer head that is waiting to pull the chassis loaded with the container is congested. These phenomena act in a vicious manner, and the container transport efficiency generally decreases.

  The present invention has been made in view of the above problems, and in the case where a container storage shelf and a chassis storage shelf are provided side by side, a technology capable of efficiently transferring a container to a chassis without delay. The purpose is to provide.

The place where the chassis on which the container is transferred by the transfer device is connected to the trailer head is located further on the land side than the place where the chassis storage shelf is arranged.

  The container transfer method according to the eighth aspect of the present invention is a chassis capable of taking out a container from a container storage shelf capable of taking out the container stored in the shelf and taking out the chassis stored in the shelf. The chassis is taken out from the storage shelf, and the container taken out from the container storage shelf is transferred to the chassis taken out from the chassis storage shelf.

  A container transfer method according to a ninth aspect of the present invention is a container transfer method according to the ninth aspect, wherein the container taken out from the container storage shelf is taken out from the chassis storage shelf. Then, the chassis is moved through a travel path through which the chassis on which the container provided in the chassis storage shelf is mounted can be passed.

Note that the components of each embodiment of the present invention are not limited to a specific configuration as long as they have a planned function, and can be arbitrarily selected (provided that there is another description below) And shall follow that explanation).
For example, a container storage shelf is provided with a shelf that can store a container, and any container that can take out the container from the shelf is sufficient, and the container type, the structure of the shelf, and the container for carrying the container into the shelf. The same applies to chassis storage shelves that are not limited in terms of devices and methods, devices and methods for unloading or removing containers from the shelves, and container storage methods on shelves.

As for the transfer device, as long as the transfer of the container to the chassis can be realized, the transfer method and device are not limited and can be arbitrarily selected.
There are no restrictions on the means (see the fifth embodiment) for bringing a container into a container transfer place from a place different from the place where the container storage shelf is arranged, as long as such carrying-in can be realized, This is true even if it is composed of a combination of a plurality of devices, devices, facilities, and the like. The same applies to the means (see the fifth embodiment) for bringing the chassis into the container transfer place from a place different from the place where the chassis storage shelf is arranged.

  In the following, a place where a container storage shelf is arranged, a place where a chassis storage shelf is arranged, and a place where a chassis onto which a container is transferred are connected to a trailer head are respectively referred to as a container storage place, a chassis storage place, and It may be called trailer head connection location.

  In the present invention, a container storage shelf for storing the container and a chassis storage shelf for storing the empty chassis are separately prepared, and the container and the chassis are taken out from the container storage shelf and the chassis storage shelf, respectively. The container taken out from the storage shelf is transferred to the chassis taken out from the chassis storage shelf. Therefore, according to the present invention, it becomes easy to organize the physical distribution related to the container and the chassis. In addition, when the container is transferred to the chassis, the arrival timing of the chassis and the container is easily matched, the transfer is stagnant, the other is in a congested state, and the container is transferred to the chassis. In addition, it is difficult to cause a situation such as a congested chassis or truck waiting, so that the transfer can be performed efficiently without any delay. Even when a specific container is transferred to a specific chassis, the transfer can be efficiently performed without delay.

The above effects are also common to the embodiments of the present invention. The specific effects produced by the embodiments of the present invention are as follows.
According to the 1st form of this invention, the container transfer equipment which has an effect common to each said form of this invention is realizable.

  In the second embodiment of the present invention, the chassis storage shelf includes a traveling path through which the chassis, the container or the chassis on which the container is mounted can pass, so that the chassis (including the chassis on which the container is transferred) or the container (the chassis) When a container including a container transferred to the destination is moved to a target place (hereinafter, also referred to as a destination place or a destination), it is not necessary to bypass the chassis storage shelf. Therefore, according to the 2nd form, a chassis or a container can be made to reach | attain a destination place in a short distance. This means that there is no need for a detour runway or ancillary equipment that was originally necessary for detouring the chassis storage shelf, which contributes to a reduction in the area occupied by the equipment and cost. It is beneficial.

  Note that the target location is, for example, (i) a location where the trailer head and the chassis are connected, and (ii) when the transfer device is disposed on the entrance side of the travel path (fourth embodiment). In the case where the transfer device is located (iii) between the location where the chassis storage shelf is located and the location where the container storage shelf is located (No. 3) or when the transfer device is arranged on the exit side of the travel path (fourth embodiment), the place where the trailer head and the chassis are connected, as in (i) above. Therefore, according to the second embodiment, in the case of (ii) above, the chassis and the container taken out from each shelf reach the container transfer location in a short time, so that the transfer is finally completed. The time required for the process can be shortened. In the case of (i) and (iii) above, the chassis on which the container is transferred will reach the trailer head connection location in a short time, so the container should be transported to the next destination earlier. Can do.

  In the third aspect of the present invention, the container transfer location is located between the chassis storage location and the container storage location, so the travel distance of the container taken out from the container storage shelf to the container transfer location is And the travel distance of the chassis taken from the chassis storage shelf to the container transfer location is eliminated, avoiding the situation where only one of the container and the chassis has to travel a significantly longer path than the other. be able to. Therefore, according to the third embodiment, when the container is transferred to the chassis, the time difference between the arrival of the chassis and the container is reduced, the arrival timing is more easily matched, and the transfer is more efficiently performed without delay. Can be done. This is particularly useful when a specific container needs to be transferred to a specific chassis in a short time.

In the 4th form of this invention, the container transfer place is located in the entrance side or exit side of the travel path through which the chassis, the container, or the chassis on which the container is mounted can be provided. If the container is on the entrance side of the travel path, every time a container is transferred to the chassis taken out from the chassis storage shelf, the container can be quickly transported to the exit side through the travel path. However, there is no congestion or stagnation due to the chassis that has been transferred to the container. Therefore, according to the fourth embodiment, since the adverse effect due to the congestion or retention of the container transferred chassis does not affect the transfer of the container to the chassis, the transfer can be performed efficiently without delay. it can.
Note that, unless the distance between the chassis storage place and the container storage place is unnecessarily separated, the configuration is the same as or substantially the same as that of the third embodiment, so that the same effect as that of the third embodiment is achieved.

  In the fourth embodiment of the present invention, if there is a container transfer place on the exit side of the travel path through which the chassis, container or chassis carrying the container can pass, the container taken out from the container storage shelf is passed through the travel path. It can be moved to the container transfer location located on the exit side, where it is transferred to the chassis (including the chassis that moves to the exit side through the travel path) taken out from the chassis storage shelf where the passage is provided. The Therefore, according to the fourth embodiment, even when the chassis storage shelf is arranged between the container storage place and the container transfer place, the container taken out from the container storage shelf is removed from the chassis storage shelf. Without detouring, the container transfer location can be reached at a shorter distance. Moreover, even if the chassis is stored in a chassis storage shelf at a position separated from the container transfer location (for example, the chassis stored near the entrance of the travel route), the container transfer location is passed through the travel route. Can also be reached. Therefore, when the container is transferred to the chassis, the time difference between the arrival of the chassis and the container can be reduced as much as possible, which contributes to efficient transfer without delay.

  In addition, if there is a container transfer place on the exit side of the traveling path through which the chassis carrying the chassis, container or container can pass, there is no container storage shelf and it will not get in the way, so at or near the container transfer place, Since the container transferred chassis and trailer head can be connected, it is possible to smoothly perform the work from transferring the container to the chassis to transporting the container to the next destination without any delay. There is also an advantage.

  In the fifth aspect of the present invention, one of the means for supplying the container to the transfer device from a location different from the container storage location and the means for supplying the chassis to the transfer device from a location different from the chassis storage location. Or both. A place different from the place where the container storage shelf is located literally means that even if a place where another container storage shelf is located, equipment of another mechanism that is not a shelf is placed. It may be a place where the container is not stored (for example, a loading platform of a traveling carriage). The same applies to a place other than the place where the chassis storage shelf is arranged, and it may be a place where equipment of another mechanism that is not another chassis storage shelf or shelf is arranged, and the chassis is stored. It may be a place that cannot be said.

  In the fifth embodiment, when one or both of the container storage shelves and the chassis storage shelves are plural, or when both shelves are not arranged in the same row or adjacent to each other, both shelves are close to each other. Even if it cannot be said, it is possible to transfer the container to the chassis using a common transfer device. This may be the case, for example, when a particular container storage shelf is missing or not stored, or when a container to be mounted on the chassis is not stored (eg the container specification does not match the chassis specification). This means that a necessary container can be taken out from another container storage shelf and mounted on the chassis using a common transfer device.

The same applies to chassis storage shelves, when a chassis is missing or not stored in a particular chassis storage shelf, or when the chassis on which the container is to be mounted is not stored (for example, the chassis specification is This means that a necessary chassis can be taken out from another chassis storage shelf and a container can be mounted using a common transfer device (when it does not meet the specifications).
Moreover, even if the container is not stored in the container storage shelf or the chassis is not stored in the chassis storage shelf, it is possible to transfer the container to the chassis using a common transfer device. .
Therefore, according to the fifth embodiment, the transfer of the container to the chassis proceeds smoothly and rationally as a whole, which contributes to the sound and efficient operation of the container terminal.

  In the sixth aspect of the present invention, the apparatus further includes a trailer head that pulls the chassis on which the container is transferred by the transfer device. Therefore, each time the container is transferred, the container transfer place The container transfer location and its surroundings are not congested or stagnated by the chassis on which the container has been transferred. Therefore, according to the sixth embodiment, the container can be transferred smoothly and efficiently without delay.

  In the seventh embodiment of the present invention, the container storage location, the chassis storage location, and the trailer head connection location are located in order from the sea side to the land side of the harbor district. For this reason, containers unloaded from a ship are stored in container storage shelves that are located closer to the ship, removed from the container storage shelves, and then removed from chassis storage shelves that are placed on the land side. In other words, it moves along the direction of the flow from the sea side to the land side, and is transported to the destination by the trailer head. Therefore, according to the seventh embodiment, the configuration and layout of the container transfer facility is relatively simple, and the operation and management of the facility are facilitated.

  According to the 8th form of this invention, the container transfer method which has an effect common to each form of said invention can be implement | achieved.

  According to the ninth aspect of the present invention, it is possible to realize a container tena transfer method that exhibits the effect of the second aspect.

That is, in the chassis storage shelf 9 of the present embodiment, the chassis to be stored are separated and independent from each other. Therefore, the chassis 59 at any position can be taken out, and the storage shelf 7 at any position can be taken out. Can be accommodated, and can be stored and taken out according to a desired selection.
On the other hand, when the chassis 59 is stored in a standing manner, it cannot be taken out or stored unless it is in order from the end.

<Transfer device>
The transfer device 11 is installed in the transfer area 17 and has a function of transferring the container 19 taken out from the container storage shelf 5 to the chassis 59 taken out from the chassis storage shelf 9.
As shown in FIG. 9, the transfer device 11 has a portal shape as a whole, and includes a lifting device 87 and a lifting member 89. The elevating member 89 is supported by a wire 91 extending from the elevating device 87 and can be moved up and down. Traveling rails 93 similar to those formed on each shelf 3 of the container storage shelf 5 are formed on the elevating member 89 so that the self-propelled spreader 31 of the stacker crane 21 can go back and forth between the spreader body 39 side. It has become.

A method of transferring the container 19 taken out from the container storage shelf 5 to the chassis 59 taken out from the chassis storage shelf 9 using the transfer device 11 configured as described above will be described.
The trailer head 57 that pulls the chassis 59 taken out from the chassis storage shelf 9 is placed on standby below the transfer device 11.
On the other hand, the container 19 is taken out from the container storage shelf 5. The method for taking out the container 19 from the container storage shelf 5 is as described above. In a state where the container 19 taken out from the container storage shelf 5 is gripped by the self-propelled spreader 31, the spreader body 39 is lifted and lowered, and the position of the lifting member 89 of the transfer device 11 is the same as shown in FIG. Get to the position. In this state, the self-propelled spreader 31 is self-propelled, and is transferred to the lifting / lowering member 89 side of the transfer device 11 while holding the container 19. When the elevator member 89 is transferred, the elevator device 87 of the transfer device 11 is driven to lower the elevator member 89 and mount the container 19 on the chassis 59. When the container 19 is mounted on the chassis 59, the trailer head 57 is started.

Next, a method for storing the container 19 in the storage shelf using the transfer device 11 will be described. The trailer head 57 that pulls the chassis 59 on which the container 19 is mounted is positioned below the lifting member 89 of the transfer device 11. In this state, the elevating member 89 is lowered to cause the self-propelled spreader 31 to grip the container 19. When the self-propelled spreader 31 grips the container 19, the elevating member 89 is raised, and the position of the elevating member 89 is adjusted to the position of the spreader body 39 of the stacker crane 21. In this state, the self-propelled spreader 31 is self-propelled to transfer the self-propelled spreader 31 to the spreader main body 39. When the self-propelled spreader 31 is transferred to the spreader body 39, the lifting device 43 is driven to move to the position of the shelf 3 in which the container 19 is stored.
When the spreader main body 39 moves to the position of the specific shelf 3, the lifting / lowering operation is stopped, and the self-propelled spreader 31 is self-propelled and moved to the traveling rail 33 provided on the shelf 3. And the holding | grip with respect to the container 19 of the self-propelled spreader 31 is cancelled | released, and the container 19 is stored in the desired shelf 3. FIG.
In the following description, the trailer head 57 connected to the chassis 59 may be referred to as a trailer.

  Next, the operation of the entire container transfer facility configured as described above will be described separately for the case where the container 19 is carried out and the case where the container 19 is stored. In addition, in the following description, since operation | movement of each apparatus which comprises the container transfer equipment 1 has already been demonstrated, the description is abbreviate | omitted.

<When unloading containers>
As shown in FIG. 1, the trailer head 57 is traveled and conveyed to the chassis storage shelf 9, the chassis 59 is taken out from the chassis storage shelf 9, and the chassis 59 is connected to the trailer head 57 to form a trailer. The trailer is moved to the transfer area 17 and stopped below the transfer device 11. In this state, the container 19 is taken out from the container storage shelf 5 and mounted on the chassis 59. When the container 19 is mounted on the chassis 59, the trailer is started and transported to the container transport destination.

<When storing containers>
The trailer on which the container 19 is mounted on the chassis 59 is stopped below the transfer device 11 in the transfer area 17. In this state, the transfer device 11 is driven to deliver the container 19 on the chassis 59 to the stacker crane 21 side. The stacker crane 21 that has received the container 19 stores the container 19 on the shelf 3. On the other hand, the trailer that delivered the container 19 moves to the chassis storage shelf 9 and delivers the chassis 59 in the chassis storage shelf 9. In the transferred chassis storage shelf 9, the chassis 59 is stored in the storage shelf 7 by the above-described operation. The trailer head 57 from which the chassis 59 has been separated moves to a predetermined waiting place.

As described above, according to the present embodiment, the operation of carrying out the container and the operation of storing the container are performed in an extremely organized manner, and the flow of the entire physical distribution can be performed smoothly.
Moreover, in this Embodiment, the container transfer area 17 where the transfer apparatus 11 is arrange | positioned is located between the place where the chassis storage shelf 9 is arrange | positioned, and the place where the container storage shelf 5 is arrange | positioned. Therefore, the distance for moving the container 19 and the chassis 59 for the transfer of the container 19 is shortened, and therefore the movement of the container and the chassis 59 in the container terminal 13 is made efficient, thereby improving the overall logistics. Smoothness is achieved.
Moreover, in this Embodiment, both the container storage shelf 5 and the chassis storage shelf 9 are made into the shelf form, and the container and the chassis 59 can be taken out selectively. Therefore, the desired chassis 59 and the desired container 19 can be taken out freely, and the optimal combination of both can be realized.

[Embodiment 2]
FIG. 10 is an explanatory diagram of the container transfer facility 94 according to Embodiment 2 of the present invention. The second embodiment is different from the first embodiment in the following points.
(a) The chassis storage shelf 96 is made a stacker crane system similarly to the container storage shelf 5 described in the first embodiment, and the chassis 59 is transported between the chassis storage shelf 96 and the transfer device 11 by the stacker crane 211. What I did,
(b) With the container 19 placed on the chassis 59, the self-propelled carriage 95 (see FIGS. 13 and 16) conveys it to the outside of the container storage shelf 5,
(c) A tunnel-type traveling path 97 through which a self-propelled carriage 95 carrying a chassis 59 carrying the container 19 can pass is provided in the chassis storage shelf 96.

  Hereinafter, differences from the first embodiment will be described.

<Chassis storage shelf>
The chassis storage shelf 96 according to the present embodiment includes multi-stage storage shelves 7, and each storage shelf 7 can accommodate the pallet 61 regardless of whether or not the chassis 59 is mounted. The chassis 59 mounted on the pallet 61 is grounded to the pallet 61 via the tire and the outrigger. Therefore, the pallet 61 is provided with a mechanism (not shown) that facilitates or ensures positioning of the chassis 59 by grounding. The storage shelf 7 may have any structure as long as it does not prevent the pallet 61 from being accommodated or taken out.
When the chassis storage shelf 96 is composed of the multi-stage and multi-row storage shelves 7, the chassis storage shelf 96 is a mechanism that enables horizontal movement of the pallet between shelves as described in the first embodiment. May be provided.

In the container storage shelf 5 of the first embodiment, the container 19 is gripped by the self-propelled spreader 31 so as to go back and forth between the shelf 3 and the stacker crane 21, but in the chassis storage shelf 96, Instead, the chassis 59 is placed on the pallet 61, and the storage shelf 7 and the stacker crane 211 side are moved by the transfer device 212 (see FIGS. 11 and 12) including an extendable fork mechanism 213 that supports the pallet 61 from below. I am doing so.
In the chassis storage shelf 96, a location adjacent to or near the crane travel path 231 is provided with a chassis 59, a container 19, and a tunnel travel path 97 through which the chassis 59 carrying the container 19 can pass. A rail 98 for running a self-propelled carriage 95 is laid in the tunnel-type traveling path 97. The rail 98 passes from the lower side of the transfer device 11 to the trailer head connecting / disconnecting area 99 that passes through the tunnel type traveling path 97 and is provided at the exit of the chassis storage shelf 96.

  As another mode, the chassis storage shelf 96 according to the present embodiment can be configured from the storage shelf 7 that does not use the pallet 61. In this case, the chassis 59 is grounded to the floor surface of each storage shelf 7 via the tire and the outrigger. Further, the storage shelf 7 and the stacker crane 211 side are moved by a transfer device 212 (see FIGS. 14 and 15) provided with an extendable fork mechanism 213 that directly mounts the chassis 59 and supports the pallet 61 from below.

<Stacker crane>
As shown in FIG. 11, the stacker crane 211 installed on the chassis storage shelf 96 includes a lifting body 103 that moves up and down between the masts 37, a lifting device (not shown) that lifts and lowers the lifting body 103, and a lifting body 103. And a transfer device 212 that moves between the elevating body 103 and the storage shelf 7 and delivers the chassis 59 placed on the pallet 61 to and from the storage shelf 7. The transfer device 212 includes a fork mechanism 213. The transfer device 212 may be configured integrally with the elevating body 103, may be separable, and may be configured such that each moves up and down independently.

The fork mechanism 213 is arranged between the pallet 61 or the chassis 59 between the stacker crane 211 side or the transfer device 212 and each storage shelf 7, and between the stacker crane 211 side or the transfer device 212 and the self-propelled carriage 95. And the mounted pallet 61 is moved (see FIGS. 12 and 13).
The fork mechanism 213 includes a three-tiered fork, a horizontal drive mechanism (not shown) that sequentially moves horizontally from each fork, and expands and contracts the entire fork mechanism 213, and moves the fork mechanism 213 up and down by a short distance in the vertical direction. And a vertical drive mechanism (not shown) that enables contact and separation between the bottom of the fork and the fork. As long as the pallet 61 can be moved between the stacker crane 21 side and each storage shelf 7, the number of overlapping forks may be one, two, four or more. Good.
The fork mechanism 213 moves the pallet 61 regardless of whether or not the chassis 59 is mounted. However, the fork mechanism 213 directly supports the chassis 59 by inserting the fork into the bottom of the chassis 59 or other appropriate location. May be configured to move (see FIGS. 14 and 15). In particular, when the chassis 59 is moved between the stacker crane 211 side or the transfer device 212 and the self-propelled carriage 95, the fork mechanism 213 does not move the pallet 61 on which the chassis 59 is mounted, but the chassis 59. It is preferable to perform only the movement because the labor of collecting the pallet 61 remaining on the self-propelled carriage 95 can be saved (see FIGS. 15 and 16).

The transfer device 212 may be a transfer cart that moves between the storage shelf 7 and the stacker crane 21 side with the chassis 59 mounted. In this case, the elevating body 103 and the storage shelf 7 are provided with rails that serve as tracks of the wheels of the elevating carriage for enabling the transfer carriage to come and go. In addition, the transfer cart is moved up and down by a short distance in the vertical direction between the mounting surface of the transfer cart and the chassis 59 (or the pallet 61 on which the chassis 59 is mounted) to prevent contact and separation between the two. A vertical drive mechanism is provided that enables. According to such a transfer cart system, when the chassis 59 is moved between the storage shelf 7 and the stacker crane 211 side, it is not necessary to use the pallet 61 for placing the chassis 59. All you have to do is use a transfer truck to place it.
If the use of the pallet 61 is acceptable, the transfer cart may be moved between the storage shelf 7 and the stacker crane 211 side while the pallet 61 on which the chassis 59 is mounted is placed. .

<Self-propelled cart>
The self-propelled carriage 95 is disposed at the position of the transfer device 11 so that the chassis 59 can be mounted with or without the pallet 61. When the stacker crane 211 shown in FIGS. 11 and 12 is used, as shown in FIG. 13, the self-propelled carriage 95 is mounted with the chassis 59 together with the pallet 61, As shown in FIG. 16, the chassis 59 is mounted without the pallet 61.

As shown in FIGS. 13 and 16, after the container 19 is placed on the chassis 59 on which the self-propelled carriage 95 is mounted from the stacker crane 21 side by the self-propelled spreader 31 provided in the stacker crane 21, the self-propelled carriage 95. Travels on the rail 98 and moves to the trailer head connecting / disconnecting area 99 through the tunnel-type traveling path 97.
In the case of the self-propelled carriage 95 shown in FIG. 13, in the trailer head connecting / disconnecting area 99, the chassis 59 is connected to the trailer head 57. 57 is pulled out from the chassis pallet 61 and thus from the self-propelled carriage 95. In the case of the self-propelled carriage 95 shown in FIG. 16, in the trailer head connecting / disconnecting area 99, the chassis 59 is connected to the trailer head 57. 57 is pulled out from the self-propelled carriage 95. In any case, it is preferable that the front portion of the self-propelled carriage 95 is inclined downward so that the mounted chassis 59 can be easily lowered.
The self-propelled carriage 95 is remotely controlled, for example, by radio, and the stop, start, etc. at a predetermined position are remotely controlled.

  11 and 14 does not need to be arranged at a certain distance below the chassis storage shelf 96. For example, any of the tunnel type running paths 97 shown in FIGS. You may arrange in the position. Therefore, even if it is a tunnel type, a part or all of the wall surface may be surrounded by the chassis shelf 7 or may not be surrounded. May not be disposed below.

  Next, the operation of the container transfer equipment 94 according to the present embodiment configured as described above will be described in a general manner when the container 19 is carried out and when the container 19 is stored. In addition, in the following description, since operation | movement of each apparatus which comprises the container transfer equipment 94 has already been demonstrated, the description is abbreviate | omitted.

<When unloading containers>
As shown in FIG. 13, the self-propelled carriage 95 is caused to travel, and is placed on the transfer device 11 to be in a standby state. In this state, the chassis 59 is unloaded from the chassis storage shelf 96 together with the pallet 61 by the stacker crane 211 shown in FIGS. 11 and 12 and placed on the self-propelled carriage 95. Alternatively, the self-propelled carriage 95 is caused to travel, and as shown in FIG. In this state, the chassis 59 from the chassis storage shelf 96 is unloaded without the pallet 61 by the stacker crane 211 shown in FIGS. 13 and 14 and placed on the self-propelled carriage 95.
Next, the container 19 is taken out from the container storage shelf 5 by the stacker crane 21 and placed on the chassis 59 mounted on the pallet 61. When the container 19 is mounted on the chassis 59, the self-propelled carriage 95 is started and travels to the trailer head connecting / disconnecting area 99 through the tunnel-type traveling path 97. When the self-propelled carriage 95 arrives at the trailer connection area, the trailer head 57 waiting there is connected and the container 19 is transported to a necessary place.

<When storing containers>
The trailer with the container 19 mounted on the chassis 59 is carried into the trailer head connecting / disconnecting area 99, the chassis 59 with the container 19 mounted on the self-propelled carriage 95 waiting there, and the chassis 59 and the trailer head 57 are separated. Depending on the mode of the chassis storage shelf 96, there may be a case where the pallet 61 is mounted on the self-propelled carriage 95 (corresponding to FIGS. 11 to 13), and the pallet 61 is not mounted on the self-propelled carriage 95. In some cases (corresponding to FIGS. 14 to 16).

  The self-propelled carriage 95 carrying the chassis 59 on which the container 19 is mounted passes through the tunnel-type traveling path 97 and travels below the transfer device 11 to stop. In this state, the transfer device 11 is driven to deliver the container 19 on the chassis 59 to the stacker crane 21 side. The stacker crane 21 that has received the container 19 stores the container 19 on the shelf 3. Further, the stacker crane 211 on the chassis storage shelf 96 side is caused to travel to the vicinity of the transfer device 212, and the transfer device 212 moves the chassis 59 on the self-propelled carriage 95 together with the pallet 61 (see FIG. 13) or without the pallet 61. (Refer to FIG. 16).

  The stacker crane 211 delivered with the chassis 59 stores the chassis 59 together with the pallet 61 (see FIG. 13) or without the pallet 61 (see FIG. 16) in a predetermined storage shelf 7 of the chassis storage shelf 96. When the chassis 59 is delivered, the self-propelled carriage 95 moves to a predetermined standby place and waits.

  The stacker crane 211 when the chassis 59 is delivered together with the pallet 61 is an example shown in FIGS. 11 and 12, and the stacker crane 211 when the chassis 59 is delivered without the pallet 61 is shown in FIGS. What is shown in FIG. 15 is an example.

As described above, in the present embodiment, the container 19 is mounted on the chassis 59, and is moved to the trailer head connection / disconnection area 99 by the self-propelled carriage 95, and the trailer head 57 in the trailer head connection / disconnection area 99 is moved. Since the trailer head 57 and the empty chassis 59 are connected, the movement in the container terminal 13 is eliminated, the traffic in the container terminal 13 is simplified, and the movement in the container terminal 13 is smooth. To be done.
In the present embodiment, the chassis storage shelf 96 includes a chassis 59, the container 19, or a travel path through which the chassis 59 on which the container 19 is mounted can pass, so that the chassis 59 (the chassis 59 to which the container 19 is transferred) is provided. When the container 19 (including the container 19 transferred to the chassis 59) is moved to a target location, for example, the trailer head connecting / disconnecting area 99, it is not necessary to bypass the chassis storage shelf 96. Therefore, according to the present embodiment, the chassis 59 or the container 19 can reach a destination such as the trailer head connecting / disconnecting area 99 in a short distance. This eliminates the need for bypassing the chassis storage shelf 96, eliminates the costs required for the detour and incidental equipment, and contributes to cost reduction.

In the above embodiment, the container 19 and the chassis 59 are stored in the container storage shelf 5 and the chassis storage shelves 9 and 96, respectively. It is also possible to provide means for transporting from one place to the transfer device 11 and use the container 19 or chassis 59 in another place.
