Description

  The present invention relates to a container terminal and a container terminal operation method, and more particularly, to a container terminal and a container terminal operation method that adjusts the difference between prosperity in a plurality of storage lanes to improve overall cargo handling efficiency.

  To rationalize container handling, a plurality of storage lanes, a portal crane that travels across each storage lane, a plurality of orbiting carts that travel between the quay apron area and the quay side of the storage yard A reciprocating carriage that travels along a track provided in the longitudinal direction of each storage lane, and a quay side transfer means for transferring containers between the reciprocating carriage and the revolving carriage of each storage lane at a quay side position of the storage yard And a land-side transfer means for transferring containers between the reciprocating carriage of each storage lane and the load chassis at the land side position of the storage yard has been proposed (see, for example, Patent Document 1). .

  The container-type crane of this container terminal is a rail-type crane, and it is not easy to move between the storage lanes, and the handling capacity of the lane is fixed depending on the number of storage lanes installed.

JP 2011-93654 A

  The present invention has been made in view of the above-mentioned problems, and its object is to provide a container terminal and a container terminal operation method that improve the overall cargo handling efficiency by adjusting the difference between prosperity in a plurality of storage lanes. It is to be.

  A container terminal according to the present invention for solving the above-described problem is a storage terminal having a plurality of storage lanes in which a large number of containers are stored, and a plurality of traveling paths that are adjacent to the storage lanes and are laid along the storage lanes. A plurality of gate-type cranes that are provided with an area and are spaced apart in the extending direction of the storage lane across both the storage lane and the at least one traveling path. A reciprocating carriage that moves in the area and transports the container reciprocates in the storage area along the traveling path, and a circulating carriage that transports the container transfers the container on one end side of the storage area. In the container terminal for transferring the container on the other end side of the storage area, an external transport vehicle for transporting the container is adjacent to one end of the storage area and the storage tray The gate crane is a tire-type portal crane that has a moving region that extends in a direction orthogonal to the direction along which the gate crane has a tire that rolls at a lower end thereof, and is freely movable. A type crane moves from one storage lane of the storage area toward the movement area via one end of the storage area, and then rotates the direction of the tire in the movement area to the storage lane. It moves in the direction orthogonal to the direction along, and then moves from the moving area toward the other storage lane via one end of the storage area.

According to this configuration, the portal crane moves from one storage lane to the other storage lane, so that the number of portal cranes arranged in each storage lane can be made different for each storage lane. You can increase or decrease the handling capacity of the lane. As a result, when there is a difference in bustle between storage lanes, the difference in bustle is suppressed, and the container loading and unloading efficiency with the ship and the container loading and unloading efficiency with the external transport vehicle are improved. Therefore, the cargo handling efficiency of the entire container terminal can be improved. Moreover, since the portal crane moves through a moving region adjacent to one end of the storage region, it is possible to ensure the safety of a manned external transport vehicle that transports the container to the outside of the container terminal. In addition, in the case of this portal crane, the foundation work of the quay is cheaper than in the case of the rail-type portal crane, which is advantageous when applied to an existing container terminal.

  Further, in the container terminal, when the portal crane moves from the one storage lane to the other storage lane, the orbiting carriage stops in areas other than the two areas of the storage area and the movement area. A configuration is desirable. Thereby, the danger that a portal crane will collide with an orbiting cart at the time of movement of a portal crane can be avoided.

  Further, in the container terminal, the storage lane extends in a direction perpendicular to the direction along the edge of the quay along the direction along the storage lane, and the moving area is an end of the storage area on the edge side of the quay. It is desirable to be adjacent to the part. According to this structure, a movement area | region and a storage area | region are arrange | positioned in order from the edge of a quay in the direction orthogonal to the direction along the edge of a quay. As a result, when each of the rotating cart, portal crane, and reciprocating cart is automated or remotely operated, the area from the edge of the quay to the other end of the storage area becomes an unmanned area, and the other end side of the storage area Can be a manned area. Therefore, the unmanned area and the manned area can be clearly distinguished, and the cargo handling efficiency can be improved while ensuring safety.

  Further, in the container terminal described above, on one end side of the storage area, a transfer area for a portal crane disposed adjacent to one end of the storage lane and an end on one end side of the storage area of the traveling path A transfer area for a reciprocating carriage disposed on the container, and the container is transferred between the rotating carriage and the portal crane in the transfer area for the portal crane, and the transfer area for the reciprocating carriage It is desirable that the container is transferred between the round carriage and the round trip carriage.

  According to this configuration, it is possible to transfer the container of the circulating cart through a plurality of routes, and it is possible to shorten the waiting time of the circulating cart at one end of the storage area. Thereby, the conveyance efficiency of the container of an orbiting trolley | bogie can be improved, and the time concerning loading and unloading from a ship can be shortened.

  In addition, in the container terminal, the orbiting carriage is provided with a lifting tool so that the container can be lifted and lowered, and transfer of the container between the orbiting carriage and the portal crane is performed on the container. Is temporarily placed on the ground of the transfer area for the portal crane, and the transfer of the container between the orbiting carriage and the reciprocating carriage is performed directly by the orbiting carriage in the transfer area for the reciprocating carriage. It is desirable that the configuration be According to this configuration, it is not necessary to provide a transfer crane, a container cradle, or the like at the container terminal when transferring the container of the circulating cart. Therefore, the portal crane can smoothly move to the moving area.

The container terminal further includes a control device for remotely controlling the portal crane, and the control device is based on the number of containers temporarily placed on the ground of each of the portal crane transfer areas. The portal crane arranged in the storage lane having a relatively small number of the temporarily placed containers is moved to the storage lane having a relatively large number of the temporarily placed containers. It is desirable that the control be performed. According to this configuration, it is possible to easily determine the difference in pros and cons of each storage lane that is difficult to discriminate, and to suppress the difference in pros and cons.

  And the operation method of the container terminal of the present invention for solving the above-mentioned problem is a plurality of storage lanes in which a large number of containers are stored, and a plurality of travels laid along the storage lanes adjacent to the storage lanes. A plurality of gates arranged in the storage area across the one storage lane and at least one traveling path at intervals in the extending direction of the storage lane. A type crane is moved along the storage lane and a reciprocating carriage for carrying the container is reciprocated along the traveling path, and the container is transferred to a circulating carriage for carrying the container on one end side of the storage area. And a container terminal operating method for transferring the container to an external transport vehicle for transporting the container on the other end side of the storage area. The storage lane in which either one of the number of the containers temporarily placed on the part side and the number of the external transport vehicles stopped on the other end side of the storage lane is relatively small among the plurality of storage lanes The number of the cranes arranged in the relatively few storage lanes is different from the number of the portal cranes arranged in the relatively many storage lanes. It is a method to do.

  According to this method, by adjusting the difference in traffic between multiple storage lanes, the efficiency of loading and unloading containers with ships and the efficiency of loading and unloading containers with external carriers can be improved, and overall cargo handling efficiency can be improved. Can be improved.

  According to the container terminal and the container terminal operation method of the present invention, the portal crane moves from one storage lane to the other storage lane, so that the number of portal cranes arranged in each storage lane can be determined for each storage lane. Can be different. As a result, when there is a difference in bustle between storage lanes, the difference in bustle is suppressed, and the container loading and unloading efficiency with the ship and the container loading and unloading efficiency with the external transport vehicle are improved. Therefore, the cargo handling efficiency of the entire container terminal can be improved.

  As shown in FIG. 2, the shuttle carrier 30 is a carrier that does not have a trolley, and has a main body 31 formed in a gate shape, and a traveling device 33 that travels on the quay 2 with a rubber tire 32 at the lower end of the main body 31. And a spreader 34 that holds the container up and down, a machine room 35 that houses a device that raises and lowers the spreader 34, and a communication device 36 that can communicate with the control facility 11. The shuttle carrier 30 is an unmanned cart that automatically operates upon reception of a signal from the control facility 11 by the communication device 36. The shuttle carrier 30 is a carrier having a smaller number of container stacks than a straddle carrier in which two or more containers are stacked.

  The portal crane 40A includes a trolley 41, a spreader 42 that moves up and down via the trolley 41, a girder 43 that extends in the x direction, and legs that extend downward from both ends of the girder 43. 44.

  Since the portal crane 40B has the same configuration as described above, the description thereof is omitted.

  The reciprocating carriage 50 includes a loading platform 51 on which a container is mounted, a carriage body 52, wheels 53, and a driving device 54. The reciprocating carriage 50 is an AGV (Automated Guided Vehicle) that travels on a set of traveling paths 8 formed of rails by wheels 53 provided with flanges. The traveling speed of the reciprocating carriage 50 is faster than the portal cranes 40A and 40B.

  The container truck 60 is a manned external transport vehicle.

  Next, two examples of the operation method of the container terminal 1 will be described.

  As shown in FIG. 1, the unloading work (work for storing containers from the ship S to the storage lane 7) when there is no difference between the storage lanes 7 is the ship S anchored with the traveling direction in the x direction. The container is transferred and stored in the order of the bridge crane 20, the shuttle carrier 30, and the portal crane 40A, and the bridge crane 20, the shuttle carrier 30, the reciprocating carriage 50, and the portal cranes 40A and 40B. is there.

  First, the bridge crane 20 moves the trolley along the boom 21 and the girder 22, raises and lowers the spreader through the trolley, and wholesales the container from the ship S to the ground of the loading / unloading area 3. At this time, the container is wholesaled to either the ground below the span of the girder 22 or the ground below the back reach according to the specifications of the quay 2.

  Next, the control facility 11 instructs the container to be transported to the shuttle carrier 30 and the storage position of the container. Next, the instructed shuttle carrier 30 stops over the container wholesaled on the ground of the loading / unloading area 3, and the spreader 34 lifts the container from the ground. Next, the shuttle carrier 30 that lifts the container moves toward the edge 2 a side of the quay wall 2 of the storage area 4.

  Next, the control facility 11 determines where to transfer the container transported so that the waiting time in the storage area 4 of the shuttle carrier 30 is shortened. Specifically, any of the following conditions: container storage position, current position of the portal cranes 40A and 40B, loading and unloading status of the containers of the portal cranes 40A and 40B, the current position of the reciprocating carriage 50, and the traveling situation of the reciprocating carriage 50 From the above, either the transfer area 12 for the portal crane or the transfer area 13 for the reciprocating carriage is selected. For example, if the container storage position is within 5 bays from the edge 2a side end of the quay 2 of the storage lane 7, the transfer area 12 for the portal crane is used. Region 13 is selected. If the current position of the reciprocating carriage 50 is far from the five bays, the portal crane transfer area 12 is selected.

  Next, when the control facility 11 selects the transfer area 12 for the portal crane, the selection is instructed to the shuttle carrier 30. Next, the instructed shuttle carrier 30 stops in the transfer area 12 for the portal crane and temporarily places the container on the ground of the transfer area 12 for the portal crane. On the other hand, when the control facility 11 selects the transfer area 13 for the carriage, the shuttle carrier 30 is instructed to select it. Next, the instructed shuttle carrier 30 stops in the reciprocating carriage transfer area 13, and the container is transferred to the reciprocating carriage 50 stopped in the reciprocating carriage transfer area 13. Next, the shuttle carrier 30 in which the container has been transferred moves to the bridge crane 20 in the loading / unloading area 3. The operation of the shuttle carrier 30 described above is automatically performed in response to an instruction from the control facility 11.

  Next, the control facility 11 directly stores the container temporarily placed on the ground of the transfer area 12 for the portal crane in the storage lane 7 by the portal crane 40A, or transfers the container from the portal crane 40A to the reciprocating carriage 50. It is selected whether to load and transfer from the reciprocating carriage 50 to the other portal crane 40B for storage. When the control facility 11 selects direct storage by the portal crane 40A, the control facility 11 instructs the portal crane 40A. Next, the portal crane 40A travels in the y direction and stores the container in the storage lane 7. On the other hand, when the control facility 11 selects storage through the transportation by the reciprocating carriage 50, the reciprocating carriage 50 and the portal crane 40B are instructed. Next, the reciprocating carriage 50 travels to the portal crane 40B. Then, the portal crane 40B stores the container carried by the reciprocating carriage 50 in the storage lane 7. The operations of the portal cranes 40A and 40B and the reciprocating carriage 50 are automatically performed in response to an instruction from the control facility 11. At this time, the portal cranes 40 </ b> A and 40 </ b> B are finely adjusted in the moving direction while the detecting device 47 detects the guiding device 17 laid on the first moving path 9. Moreover, it moves, confirming the safety of the advancing direction (y direction) with the y direction confirmation apparatus 48. FIG.

In this way, the unloading work when there is no difference between the storage lane 7 and the unloading work is that the shuttle carrier 30 transfers the container through the two routes of the transfer area 12 for the gate crane and the transfer area 13 for the reciprocating carriage. Thus, the container transportation efficiency from the bridge crane 20 is increased. The container is stored in two paths: storage of the container by the portal crane 40A and storage of the container by the portal crane 40B via the reciprocating carriage 50, thereby increasing the storage efficiency of the storage lane 7. Specifically, on the edge 2a side of the quay 2 of the storage lane 7, the container is transferred between the reciprocating carriage 50 and the portal crane 40A by being directly stored by the portal crane 40A without passing through the reciprocating carriage 50. Reduce the time it takes. On the other hand, on the opposite side of the edge 2 a of the quay 2, the time required for transporting the container is reduced by transporting the container by utilizing the speed of the carriage 50.

  The loading operation (operation for loading containers from the storage lane 7 onto the ship S) is the reverse procedure of the unloading operation.

  Further, when there is no difference between the storage lanes 7 and the carry-out operation (operation of transferring containers from the storage lanes 7 to the container truck 60), the control facility 11 in the container truck transfer area 14 of the container truck 60 In order to shorten the waiting time, the container stored in the storage lane 7 is directly transferred by the gate crane 40B, or the container stored in the storage lane 7 is transferred from the gate crane 40A via the reciprocating carriage 50 to the gate. Decide whether to transfer with the type crane 40B. Then, the transfer is performed according to the determination, but the transfer operation of the container from the portal crane 40B to the container truck 60 is not automatic, but is a remote operation from the control facility 11 in order to improve safety. Further, when a container is transferred from the portal crane 40B to the container truck 60, the container crane 60B is placed over the container truck 60 after the portal crane 40B matches the position of the container truck 60 to which the trolley 41 is transferred. In addition, the trolley 41 is not moved except for fine adjustment after the portal crane 40B straddles the container truck 60. The carrying-in work (work for storing containers from the container truck 60 to the storage lane 7) is the reverse procedure of the carrying-out work.

  The unloading work when there is a difference between the storage lanes 7 in each storage lane 7 is the above-described storage lane 7 where the unloading work is stagnant, and the portal crane 40A disposed in the storage lane 7 where the work is progressing. A process of moving is added. Here, it is assumed that the storage lane that is progressing is 7A, and the storage lane that is stagnating is 7B.

  First, as shown in FIG. 3, the control facility 11 stores the container storage status of each storage lane 7 in the future, the temporary storage number of containers in the transfer area 12 for the portal crane, and the transfer in the transfer area 13 for the carriage. From the loading situation, the storage lane 7A where the work is progressing and the storage lane 7B which is stagnating are discriminated. In this embodiment, based on the number of containers temporarily placed on the ground in the transfer area 12 for the portal crane, the number of the storage lanes 7A and the number of containers temporarily placed are relatively small. It is judged the difference between the busy and the storage lane 7B. Here, the relatively large or small number means a case where all the storage lanes 7 in the storage area 4 are compared.

  Next, the control facility 11 instructs the portal crane 40A in the storage lane 7A. Next, the instructed portal crane 40 </ b> A moves toward the edge 2 a of the quay 2. At this time, the control facility 11 instructs the shuttle carrier 30, and the shuttle carrier 30 moves from the storage area 4 and the movement area 15 to the loading / unloading area 3 other than the movement area 15 and stops.

  Next, as shown in FIG. 4, when the control facility 11 confirms that all the shuttle carriers 30 have stopped in the loading / unloading area 3 other than the moving area 15, the portal crane 40 </ b> A is transferred to the portal crane transfer area. It moves over 12 to the moving area 15. Next, the direction of the rubber tire 45a of the portal crane 40A is changed from the y direction to the x direction by remote control. At this time, the extending direction of the girder 43 of the portal crane 40A remains in the x direction. Next, the portal crane 40A is moved in the x direction along the moving region 15 by remote control. At this time, the direction of travel of the portal crane 40A is detected by the detection device 47 and finely adjusted with the guidance device 17 laid in the moving region 15. Moreover, it moves, confirming the safety of the advancing direction (x direction) with the x direction confirmation apparatus 49. FIG.

  Next, as shown in FIG. 5, the portal crane 40 </ b> A is moved to a set of first movement paths 9 across the storage lane 7 </ b> B. Next, the direction of the rubber tire 45a of the portal crane 40A is changed from the y direction to the x direction by remote control. Next, the control facility 11 instructs the portal crane 40A. The instructed portal crane 40A moves from the moving area 15 toward the storage lane 7B.

  Next, as shown in FIG. 6, when the portal crane 40A enters the storage area 4 from the moving area 15, the control facility 11 instructs the shuttle carrier 30, and the shuttle carrier 30 moves according to the instructions.

  The following work is performed in the same manner as the above-described unloading work. However, unlike the unloading work described above, the storage lane 7B includes two portal cranes 40A and one portal crane 40B. Therefore, one portal crane 40A is in charge of the transfer area 12 for the portal crane and the edge 2a side of the quay 2 of the storage lane 7B, and the other portal crane 40A is in charge of the storage lane 7B. The portal crane 40B is in charge of the opposite side of the edge 2a of the quay 2 of the storage lane 7B. As a result, the moving distance of the portal cranes 40A and 40B is shortened, and the loading and unloading processing capacity is increased by performing the transfer and storage of the containers with three units.

  The carry-out work and the carry-in work when there is a difference between the storage lanes 7 are determined based on the number of container trucks 60 stopped in the container truck transfer area 14.

  According to the container terminal 1 and its operation method, first, the tire-type portal cranes 40A, 40B are moved from one storage lane 7A to the other storage lane 7B, so that they are arranged in each storage lane 7. The number of portal cranes 40 </ b> A and 40 </ b> B to be used can be made different for each storage lane 7. Therefore, the cargo handling capacity of each storage lane 7 can be increased / decreased, and when there is a difference between the storage lanes 7, the difference between the storage and the operation can be suppressed. Thereby, since the loading / unloading efficiency of the container between the ships S and the container loading / unloading efficiency by the container truck 60 can be improved, the overall cargo handling efficiency can be improved.

  Second, since the portal cranes 40A and 40B move via the moving region 15 adjacent to one end of the storage region 4, the portal cranes 40A and 40B are moved in an area where the container truck 60 does not enter. Can do. Thus, the portal cranes 40A and 40B can be lane-changed only by an instruction from the control facility 11 and a remote operation without making the driver of the container truck 60 fully aware or calling attention. Therefore, the safety of the container truck 60 that transports the container to the outside of the container terminal 1 can be ensured.

  Third, in the case of the tire type portal cranes 40A and 40B, the foundation work of the quay 2 is cheaper than the rail type portal crane, which is advantageous for application to an existing container terminal. Become.

  Fourth, the width of the moving region 15 in the y direction can be shortened by moving the moving region 15 with the portal cranes 40A and 40B with the extending direction of the girder 43 in the x direction. Therefore, even when the loading / unloading area 3 is narrow, the portal cranes 40A and 40B can be lane-changed.

In addition, the loading / unloading area 3, the storage area 4, and the carry-in / load-in area 5 are arranged in this order from the edge 2a of the quay 2 to the y-direction, so that the shuttle carrier 30, the portal cranes 40A and 40B, the reciprocating carriage 50
When each of these is automated or operated remotely, the area from the edge 2a of the quay 2 to the container truck transfer area 14 in the storage area 4 is defined as an unmanned area, and the container truck transfer area 14 in the storage area 4 is It can be a manned area. Therefore, the unmanned area and the manned area can be clearly distinguished, and the cargo handling efficiency can be improved while ensuring safety.

  In addition, the transfer of the container of the shuttle carrier 30 can be performed by a plurality of paths, and the standby time of the shuttle carrier 30 at the end of the storage area 4 on the edge 2a side of the quay wall 2 can be shortened. Thereby, the conveyance efficiency of the container of the shuttle carrier 30 can be improved, and the time concerning loading to the ship S and unloading from the ship can be shortened.

  Furthermore, by using the shuttle carrier 30 as the circulating carriage, it is not necessary to provide a transfer crane, a container cradle, or the like in the container terminal 1 when transferring the container. Accordingly, the portal cranes 40A and 40B can smoothly move to the moving region 15.

  In addition, the difference between the storage lanes 7 is based on the number of containers temporarily placed on the ground in the transfer area 12 for the portal crane and the number of container trucks 60 stopped in the transfer area 14 for the container truck. Judgment. Thereby, the difference of the busyness of each storage lane 7 can be judged easily, and the difference can be suppressed.

  In the embodiment, an example in which the storage lane 7 extends in the direction y along the storage lane has been described. However, when the storage lane 7 is applied to a quay specification or a conventional container terminal, the storage lane A configuration in which the direction along the storage lane extends in the x direction may be employed.

  In the embodiment, the example in which the shuttle carrier 30 is used as the circulating carriage has been described, but the present invention is not limited to this. For example, a straddle carrier capable of stacking containers at two or more levels can be used. Moreover, the conveyance trolley | bogie which does not have hanging tools, such as a spreader, can also be used. However, in the case of using a transport carriage, it is preferable to provide a transfer stand in the transfer area 12 for the portal crane or the transfer area 13 for the reciprocating carriage.

  In addition to the configuration of the portal cranes 40A and 40B of the embodiment, providing a mechanism for adjusting the load balance of both legs in a state where the gyrostar and the container are suspended is advantageous when moving automatically. It is.
