Description

  The present invention relates to a container terminal and a method of operating the same, and more particularly, to a container terminal that improves cargo handling efficiency and a method of operating the same.

  There has been proposed a container terminal that determines the storage position of a container in a storage lane based on the operation status of a portal crane in each storage lane and the number of stacked containers (the number of stages in the height direction) (for example, see Patent Document 1). ).

JP 2005-75592 A

  By the way, in the container terminal, the work is carried out by the overlap between the cargo handling work on the yard carrier that transports the container between the container ship and the storage lane and the cargo handling work on the foreign transport vehicle that transports the container between the storage lane and the outside. The hustle and bustle occurs.

  The timing at which loading and unloading work on the yard carrier in the storage lane occurs depends on the arrival time of the target container ship. At this time, if the storage position of the container to be subjected to the cargo handling operation on the yard carrier and the storage position of the container to be subjected to the cargo handling operation to the foreign carrier overlap, the loading and unloading operation to the yard carrier is prioritized. Wait for cargo handling work on the transport vehicle. Here, the situation where the storage positions of the containers are overlapped is a situation in which the container to be handled by the on-premise carrier and the container to be handled by the foreign carrier are in the same bay or in the same lane. The congestion of the foreign transport vehicle due to the standby of the cargo handling work on the foreign transport vehicle causes a decrease in the cargo handling efficiency of the container terminal.

  In addition, when loading and unloading containers stored in various places in the storage lane, the distance that the portal crane reciprocates in the storage lane becomes longer, and the time required for the portal crane to reciprocate becomes longer. The portal crane may move to another lane in addition to moving only in the same storage lane. The prolonged time required for the reciprocating movement of the portal crane also causes a decrease in the cargo handling efficiency of the container terminal.

  Since the container terminal described in Patent Document 1 does not consider the overlap between the cargo handling work on the yard carrier and the cargo handling work on the foreign carrier, congestion occurs due to the standby of the cargo handling on the foreign carrier. Further, the container terminal described in the above-mentioned Patent Document 1 considers the operation status and the current position of the portal crane at the present time, but the efficiency of the cargo handling work of the portal crane that will occur in the future for the stored containers. Do not consider. Therefore, the plurality of stored containers are stored without regularity in the storage lane, and the time required for the reciprocating movement of the portal crane becomes longer due to the cargo handling work on the containers. As described above, the container terminal described in Patent Literature 1 has a problem that the cargo handling efficiency is reduced.

  An object of the present invention is to reduce the time required for reciprocating movement of a portal crane while reducing the congestion caused by the standby of an alien transport vehicle due to the overlap of the cargo handling operation on a yard transport vehicle and the cargo handling operation on an alien transport vehicle, An object of the present invention is to provide a container terminal capable of improving cargo handling efficiency and a method of operating the container terminal.

  The container terminal of the present invention that achieves the above object moves along a storage lane across the storage lane in the width direction of the stored container and the storage lane extending in the length direction of the stored container. A container crane which is configured to store a container transported by an external carrier to the outside and a container transported from the outside in the storage lane, wherein the storage lane is A plurality of containers which are divided into three or more sections in the vertical direction and which are stored in the sections, are characterized in that the loading and unloading work of the portal crane with respect to the plurality of containers and the foreign transport vehicle is unified. And

  The method of operating a container terminal according to the present invention that achieves the above object includes a storage lane extending in the length direction of a stored container, a storage lane extending across the storage lane in the width direction of the stored container. In a method of operating a container that is transported to the outside by a foreign carrier and a container terminal that stores containers transported from outside by a portal crane moving along, unique identification information of the container is input to the control device. Based on the input identification information, the control device determines the status of the loading and unloading operation of the portal crane for the container and the foreign carrier having the identification information previously input in association with the identification information. Identifying and storing the container having the identification information by the control device based on the identified situation of the cargo handling work. The storage device is set at a position where the situation of the cargo handling operation of a plurality of containers stored in the storage lane divided into three or more sections in the length direction is unified, and the gate is controlled by the control device. It is characterized by giving an instruction to the mold crane to store the container having the identification information at the set storage position.

  According to the present invention, by unifying the situation of the cargo handling work in a plurality of containers stored in each of the sections of the storage lane, the cargo handling operation on the yard transport vehicle and the cargo handling operation on the foreign transport vehicle overlap in the same section. That can be avoided. Thereby, it is advantageous to alleviate the congestion caused by the standby of the foreign transport vehicle due to the overlap between the cargo handling operation on the yard transport vehicle and the cargo handling operation on the foreign transport vehicle, and the cargo handling efficiency can be improved.

  In addition, by unifying the status of cargo handling work for multiple containers stored in the same block, and by collecting the containers to be handled for each cargo handling situation, the portal crane is stored in the block. The reciprocating movement when carrying out the cargo handling work on the plurality of containers thus performed can be reduced. Thereby, it is advantageous to shorten the time required for moving the portal crane in the storage lane, and the cargo handling efficiency can be improved.

  Hereinafter, embodiments of a container terminal and a method of operating the same according to the present invention will be described. The direction in the figure is based on the container C stored in the storage lane 20 of the container terminal 10. Specifically, the X direction is the length direction of the container C, the extending direction of the storage lane 20, the Y direction is the width direction of the stored container C, and the portal crane 18 is the direction across the storage lane 20, The Z direction is the vertical direction.

  Each section of the storage lane 20 is defined as a lane (A lane to G lane). In the storage lane 20, the section in the X direction is bay (A bay to D bay), the section in Y direction is row (A row to F row), and the section in Z direction is tier (A tier to F tier). .

  As illustrated in FIGS. 1 to 8, the container terminal 10 of the first embodiment serves as a node between the marine transportation and the land transportation of the container C, and performs the loading and unloading operation on the yard transport vehicle 11 and the outbound transportation vehicle 12. It is a port facility where work is performed. The premises transport vehicle 11 transports the container C between the container ship Sx and the storage lane 20, and the foreign transport vehicle 12 transports the container C between the storage lane 20 and an external land facility.

  As illustrated in FIG. 1, the container terminal 10 is divided into a gate area 14, a container yard 15, and a cargo handling area 16 in order from the land side to the sea side in the Y direction. The container yard 15 is divided into a sea side area 15a on the Y direction sea side and a land side area 15b on the Y direction land side. In addition, the dotted line which traverses the container yard 15 in the figure has shown the boundary of the sea side area 15a and the land side area 15b of the container yard 15. This boundary may be a halfway position in the Y direction in the container yard 15, and may not be the center in the Y direction. In addition, a boundary that separates the sea side area 15a and the land side area 15b (dotted line in the figure) may be set, for example, for each of the two rows of storage lanes 20 in FIG. In some cases, no border is provided.

  The gate area 14 includes a gate 17 through which the foreign transport vehicle 12 passes. The container yard 15 includes a plurality of storage lanes (also referred to as storage blocks) 20 in which a large number of containers C are stored, and a plurality of portals running in the X direction along the storage lanes 20 across the storage lanes 20 in the Y direction. A crane 18 is provided. The number of portal cranes 18 arranged in one storage lane 20 is not particularly limited, and the portal crane 18 may be configured to be movable between a plurality of storage lanes 20. The cargo handling area 16 includes a plurality of quay cranes 19 running on rails laid in the X direction along the quay where the container ship Sx berths.

  The plurality of storage lanes 20 arranged in the container yard 15 extend in the X direction, which is the length direction of the stored container C. The plurality of storage lanes 20 are arranged at intervals in the X direction and the Y direction.

The storage lane 20 is divided into three or more sections in the X direction. More specifically, the storage lane 20 according to the embodiment includes a bay 21 (a bay 22 dedicated to loading, a bay 23 dedicated to unloading, and a bay 23 dedicated to unloading, which will be described later). 24 generic name). In one bay 21, one container C can be arranged in the X direction, a plurality of containers C can be arranged in the Y direction, and a plurality of containers C can be arranged in the Z direction. For example, in one storage lane 20 in the figure, eighteen bays 21 are continuously arranged in the X direction. The number of sections in the storage lane 20 may be three or more. For example, a plurality of bays 21 adjacent to each other may be one section. However, since the cargo handling is instructed to the portal crane 18 in units of the bays 21, it is advantageous to manage the container C for each bay 21 by making the bay in the storage lane 20 a bay 21.

  The storage lane 20 arranged in the sea side area 15a stores a loading container (also referred to as an export container) Ca as a container to be loaded on the container ship Sx. On the other hand, in the storage lane 20 arranged in the land side area 15b, an unloading container (also referred to as an import container) Cb is stored as a container unloaded from the container ship Sx. That is, in this embodiment, the plurality of storage lanes 20 arranged in the container yard 15 are distinguished into two types of lanes: a lane in which the loading container Ca is stored and a lane in which the unloading container Cb is stored. . In the case where the storage lanes 20 extend in the Y direction, one end of the storage lane 20 on the sea side exists in the sea side area 15a, and the other end of the storage lane 20 exists in the land side area 15b. It may be.

  That is, each of the plurality of bays 21 in the storage lanes 20 (A lanes to D lanes) arranged in the sea-side region 15a has one loading bay 22 in which only the loading containers Ca are stored and one container C. And an empty bay 24 that is not stored. On the other hand, each of the plurality of bays 21 in the storage lanes 20 (E lanes to H lanes) arranged in the land side area 15b has a bay 23 dedicated to unloading where only the unloading container Cb is stored and an empty bay 24. It consists of.

  The container terminal 10 includes a management building 30. In the management building 30, a control system 31 is installed. The control system 31 is communicably connected to the premises transport vehicle 11, the portal crane 18, and the quay crane 19 via a communication device (not shown). The control system 31 is communicably connected to the information acquisition device 32 and the instruction device 33.

  The control system 31 is hardware including a CPU that performs various types of information processing, an internal storage device that can read and write a program used for performing the various types of information processing and information processing results, and various interfaces.

  The information acquisition device 32 is a device that is installed at the entrance of the container yard 15 and acquires the unique identification information Cx of the container C transported inside the container yard 15. In this embodiment, the information acquisition device 32 is set both in the vicinity of the gate 17 which is an entrance on the Y direction land side of the container yard 15 and in the vicinity of the quay crane 19 which is an entrance on the Y direction sea side. The information acquisition device 32 acquires the identification information Cx when the container C is transported from the outside by the foreign transport vehicle 12 and when the container C is transported by the container ship Sx and unloaded by the quay crane 19. As the identification information Cx, a container number is exemplified.

The information acquisition device 32 only needs to be able to directly or indirectly acquire the identification information Cx. For example, as the information acquisition device 32 on the Y direction sea side of the container yard 15, a quay crane 19, a barcode reader, a camera, and an image recognition system installed on the ground near the quay crane 19 are exemplified. In addition, an in-vehicle terminal of the premises transport vehicle 11 is also exemplified. In addition, a handy terminal that transmits identification information Cx directly and visually confirmed by a worker to the control system 31 is also exemplified. The information acquisition device 32 on the land side in the Y direction of the container yard 15 recognizes the unique vehicle number of the foreign carrier 12 and indirectly acquires the identification information Cx of the container C carried by the foreign carrier 12. An example of an apparatus for performing the above is shown. Further, an input device such as a touch panel which is installed at the gate 17 and directly inputs the identification information Cx by the driver of the foreign carrier 12 is also exemplified. As described above, the information acquisition device 32 only needs to be able to acquire the identification information Cx of the container C when the container C is transported inside the container yard 15, and the installation position and the specific device are not limited.

  The instruction device 33 is a device that instructs the foreign transport vehicle 12 on the storage position Px designated by the control system 31. Examples of the instruction device 33 include a display device that displays the storage position Px, a device that issues a management slip indicating the storage position Px, and a speaker that indicates the storage position Px by voice.

  As illustrated in FIGS. 2 to 5, the plurality of containers C stored in the bays 21 (22, 23, 24) are handled by the portal crane 18 with respect to the plurality of containers C and the foreign transport vehicle 12. Is unified.

  Specifically, the status of the cargo handling operation is as follows. The loading container Ca transported to the foreign transport vehicle 12 in the empty bay 24 of the storage lane 20 arranged in the seaside area 15a is stored in the empty bay 24 by the portal crane 18. This is the scheduled date Dx at which the work for forming the bay 22 dedicated to loading is performed. In addition, the status of the cargo handling operation is as follows: the unloading container Cb stored in the unloading bay 23 in the storage lane 20 is arranged in the land side area 15b, and the unloading container Cb stored in the unloading bay 23 is transported by the portal crane 18. This is the scheduled date Dy when the work of loading the vehicle 12 to form the empty bay 24 is performed.

  That is, the storage lane 20 arranged in the sea side area 15a is a lane where the empty bay 24 is changed to the bay 22 dedicated to loading on the scheduled date Dx, and the storage lane 20 arranged in the land side area 15b. Is a lane in which the unloading-dedicated bay 23 changes to an empty bay 24 after the scheduled date Dy.

  The loading container Ca stored in the storage lane 20 has been unloaded from the foreign transport vehicle 12 by the portal crane 18 for a certain period including before and after the scheduled date Dx. On the other hand, the unloading container Cb stored in the storage lane 20 is to be loaded and unloaded by the foreign transport vehicle by the portal crane 18 for a certain period including before and after the scheduled date Dy.

  The scheduled dates Dx and Dy are predicted values and may be different from the date and time when the cargo handling operation is actually performed by the portal crane 18. That is, the unification of the status of the cargo handling work in the plurality of containers C stored in one bay 21 and the unification of the scheduled dates Dx and Dy are based on the fact that the date and time when the cargo handling work was actually performed is the scheduled date Dx Indicates that they are the same in the work period over several days before and after. Note that even if the scheduled dates Dx and Dy are the same, the cargo handling work may not be performed within the working period in exceptional cases.

  Specifically, a plurality of loading containers Ca stored in the bay 22 dedicated to loading in the B bay in FIG. 2 are used for loading and unloading operations from the foreign transport vehicle 12 transported from the outside by the portal crane 18 to the storage lane 20. Are the same on the scheduled date D2. The plurality of loading containers Ca stored in the bay 22 dedicated to loading in the C bay have the same scheduled date D1. The plurality of loading containers Ca stored in the loading bays 22 of the A bay and the D bay in FIG. 3 have the same scheduled date D3.

The plurality of unloading containers Cb stored in the unloading bay 23 of the A-bay in FIG. 4 are scheduled to be loaded on the foreign carrier 12 by the portal crane 18 and transported to the outside of the container terminal D4. Are identical. The plurality of unloading containers Cb stored in the unloading bay 23 of the C bay have the same scheduled date D5. The plurality of unloading containers Cb stored in the unloading bay 23 of the B bay in FIG. 5 have the same scheduled date D6.

  The plurality of loading containers Ca stored in the same loading-only bay 22 may have the same scheduled date Dx, but more preferably be loaded on the same container ship Sx. Regarding the loading containers Ca in the same bay 22 dedicated to loading, even if the scheduled date Dx is unified, the actual timing of loading and unloading by the portal crane 18 is different if the container ship Sx to be loaded is different. Therefore, the plurality of loading containers Ca stored in the same loading bay 22 are unified with the container ship Sx to be loaded in addition to the scheduled date Dx. It becomes possible to match the timing of loading.

  As described above, in order for the loading container Ca of the same bay 22 dedicated for loading to be loaded on the same container ship Sx, the empty bay 24 must be opened before the loading container Ca is stored in the storage lane 20. It is formed. The bay 22 dedicated to loading is formed by storing the loading container Ca loaded on the same container ship Sx in the empty bay 24.

  Specifically, the plurality of loading containers Ca in the B bay in FIG. 2 are loaded on the same container ship S2. The plurality of loading containers Ca in the C bay are loaded on the same container ship S1. A plurality of loading containers Ca in the A bay and the D bay in FIG. 3 are loaded on the same container ship S3. The A bay and the D bay are empty bays 24 in FIG. 2 and the bays 22 exclusively for loading in FIG.

  Although bays 21 having the same unloading operation status in one storage lane 20 may be arranged adjacent to each other in the X direction, the plurality of portal cranes 18 simultaneously perform bays 21 adjacent to each other in the X direction. Can not do. Therefore, when there are a plurality of bays 21 having the same cargo handling status in one storage lane 20, the bays 21 are separated from each other in the X direction of the storage lane 20 so that they can be loaded and unloaded by a plurality of portal cranes 18 at the same time. It is desirable to be done.

  In this embodiment, as illustrated in FIG. 3, if the portal cranes 18 adjacent to each other in the X direction are separated from each other by at least the length of two bays 21 adjacent to each other in the X direction, the cargo handling operation can be performed at the same time. It is possible to do. Therefore, the A-bay and the D-bay having the same cargo handling situation are spaced apart from each other by a space corresponding to two of the B-bay and the C-bay. The separation distance between the bays 21 in the same cargo handling situation is not particularly limited as long as the portal cranes 18 can carry out cargo handling at the same time. For example, bays 21 having the same cargo handling status may be arranged in one storage lane 20 at both ends in the X direction. Further, three or more bays 21 having the same cargo handling situation may exist in one storage lane 20.

  The plurality of loading containers Ca stored in one loading-dedicated bay 22 further have an average weight of the containers C stored upward in the Z direction as compared to the average weight of the containers C stored downward in the Z direction. Is preferably heavy. Specifically, the container C having a heavy weight among the tiers A to F is preferentially stored sequentially from the tier F. As described above, by storing the heavy loading container Ca in the bay 22 dedicated to loading upward in the Z direction, when loading the container ship Sx, it is possible to load near the bottom of the container ship Sx. It will be advantageous.

In the plurality of containers C stored in one bay 21, in addition to the unification of the scheduled dates Dx and Dy, the time in which the Z-direction loading is carried out even in the scheduled dates Dx and Dy is performed. It is preferable to use a stacking method according to the following. That is, the container C having a shorter cargo handling time on the scheduled dates Dx and Dy among the tiers A to F is preferentially stored sequentially from the F tier. For example, in the bay 22 dedicated to loading unified on the scheduled date Dx, a loading container Ca with a fast loading time is loaded upward in the Z direction, and a late loading container Ca is loaded downward in the Z direction. Further, in the unloading bay 23 unified on the scheduled date Dy, the unloading container Cb, which is unloaded by the foreign transport vehicle 12 and transported to the outside, has a fast unloading container Cb upward in the Z direction and a slow unloading container Cb has a slow unloading container Cb. It is piled down in the direction. As described above, storing the container C in the same bay 21 in which the time during which the cargo handling work is performed earlier is stored in the upper part in the Z direction is advantageous in reducing the work to be dug up during the cargo handling.

  As illustrated in FIGS. 6 and 7, the scheduled dates Dx and Dy are predicted based on the experimental data, and are predicted based on the physical distribution information Lx associated with the unique identification information Cx of the container C. It is a schedule. The scheduled date Dx is an execution date before the container terminal 10 is operated, in which the loading and unloading work of the portal crane 18 is performed on a plurality of containers C and the foreign transport vehicles 12 having substantially the same distribution information Lx experimentally beforehand. And the number are measured, and predicted based on a certain rule shown in the measurement result.

  The physical distribution information Lx is information stored in advance in an internal storage device of the control system 31, and is input together with an operation schedule of the container ship Sx. The logistics information Lx is information that can set the storage position Px of the container C in the container yard 15, and includes at least container ship information, destination and source information of the container C, and time information. It is preferable to include the weight information of the container C. The container ship information is information indicating whether the container ship Sx berths at the container terminal 10 or the container ship Sx leaves the shore, and is also scheduled to be operated by the container ship Sx. The transport destination and transport source information of the container C is information indicating a place where the container C is transported and arrives and a place where the container C is departed. Specifically, the shipper of the container C, the destination port of the container ship Sx, and the destination port It is information including. The time information is information indicating the relationship between the contents of the container C and the time when the container C was stored in the storage lane 20. The weight information is information indicating the weight of the container C.

  The regularity of the loading containers Ca reaches a peak at which the number of the loading containers Ca transported from the outside by the foreign transport vehicle 12 is stored in the storage lane 20 by the date and time when the container ship Sx berths (enters the port). The rule is that there is a date and time. On the other hand, the regularity of the unloading container Cb is determined by the date and time when the number of unloading containers Cb unloaded from the container ship Sx is stored in the storage lane 20 and then transported to the outside by the foreign transport vehicle 12. It is a regularity that exists.

  As illustrated in FIG. 6, the regularity of the loading container Ca is based on the date and time when the container ship Sx berths (the date and time when the container ship Sx starts loading). For example, based on the loading container Ca of the physical distribution information L2, the loading container Ca of the physical distribution information L1 is such that the container ship S1 to be loaded from the implementation date when the number of storage containers in the storage lane 20 reaches the peak is offshore. The implementation date is long. The loading container Ca of the distribution information L3 has a short period from the implementation date when the number of containers stored in the storage lane 20 reaches a peak to the implementation date when the container ship Sx to be loaded leaves the shore.

  As illustrated in FIG. 7, the regularity of the unloading container Cb is based on the date and time when the container ship Sx berths (the date and time when unloading starts from the container ship Sx). For example, based on the unloading container Cb of the logistics information L5, the unloading container Cb of the logistics information L4 is from the implementation date when the container ship Sx berths to the implementation date when the number of containers transported to the foreign transport vehicle 12 reaches the peak. Is long. The unloading container Cb in the physical distribution information L6 has a short period from the implementation date when the container ship Sx berths to the implementation date when the number of containers transported to the foreign transport vehicle 12 reaches the peak.

  As described above, the containers C having the same physical distribution information Lx have a certain regularity that they reach a peak in the situation of the cargo handling work. Therefore, by setting the peaks as the scheduled dates Dx and Dy, the control system 31 can predict the scheduled dates Dx and Dy based on the physical distribution information Lx associated with the identification information Cx of the container C. become.

  The scheduled dates Dx and Dy of the container C are always measured by the instruction from the control system 31 while the container terminal 10 is operating, and the date and time when the portal crane 18 has performed the cargo handling operation based on the instruction is measured. It may be corrected based on the measured result.

  For example, as illustrated in FIG. 6, the scheduled date D1 and the scheduled date D3 in the physical distribution information L1 and the physical distribution information L3 substantially coincide with the respective peak execution dates. On the other hand, the scheduled date D2 of the loading container Ca in the physical distribution information L2 is different from the peak implementation date indicated by the measurement result. In such a case, the scheduled date D2 of the loading container Ca of the distribution information L2 is corrected to the peak execution date of the measurement result.

  Further, as illustrated in FIG. 7, the scheduled date D4 and the scheduled date D6 in the distribution information L4 and the distribution information L6 substantially coincide with the respective peak execution dates. On the other hand, the scheduled date D5 of the unloading container Cb in the distribution information L5 is different from the execution date of the peak indicated by the measurement result. In such a case, the scheduled date D5 of the unloading container Cb in the distribution information L5 is corrected to the peak execution date of the measurement result.

  As described above, it is preferable to always perform learning (correction based on the measurement results) from the measurement results that are constantly accumulated during the operation of the container terminal 10 as the data mining. Performing data mining is advantageous for improving the accuracy of the scheduled date Dx of the container C.

  Further, the corrected scheduled date D5 of the unloading container Cb in the distribution information L5 is closer to the scheduled date D6 of the unloading container Cb in the distribution information L6. In such a case, the unloading bay 23 in which the unloading container Cb of the distribution information L5 is stored and the unloading bay 23 in which the unloading container Cb of the distribution information L6 is stored are connected by a plurality of gates. It is preferable to dispose them in the X direction so that they can be loaded and unloaded almost simultaneously by the mold crane 18.

  As illustrated in FIG. 8, the control system 31 includes an empty bay setting unit 34, a storage position setting unit 35, and an instruction unit 36 as functional elements. These functional elements are stored as a program in the internal storage device of the control system 31, read out by the CPU, and executed. Each functional element may be configured by individual hardware such as a programmable logic controller. Further, each functional element may be combined into one functional element.

  The empty bay setting unit 34 is a functional element that sets the position Qx of the empty bay 24 in each of the storage lanes 20 so that the status of the cargo handling work of the plurality of containers C stored in the same bay 21 is unified. The storage position setting unit 35 is a functional element that sets the storage position Px of the container C in the storage lane 20 based on the unique identification information Cx of the container C. The instructing unit 36 is a functional element that issues an instruction to the portal crane 18 to form the empty bay 24 at the set position Qx, and to store the container C at the set storage position Px. Is a functional element that gives an instruction to

As illustrated in FIGS. 9 and 10, the method of storing the loading container Ca in the storage lane 20 in the operation method of the container terminal 10 is a method in which two major steps are performed. One is a step which starts when an operation schedule of the container ship Sx on which the loading container Ca is loaded is input, and forms an empty bay 24 at a predetermined position Qx of the storage lane 20. The other is started when the foreign transport vehicle 12 transports the target loading container Ca from the outside, sets the storage position Px of the loading container Ca, and This is a step of issuing an instruction to carry the cargo at the set storage position Px.

  As illustrated in FIG. 9, the operation schedule of the container ship Sx on which the loading container Ca is loaded and the distribution information Lx of the loading container Ca loaded on the container ship Sx are input to the control system 31. Then, the step of forming the empty bay 24 is started.

  When the operation schedule and the distribution information Lx are input, the empty bay setting unit 34 of the control system 31 determines whether or not the scheduled date Dx (the berthing date of the container ship Sx) is the next day (S110). In this embodiment, the date is set on the next day, but this date can be set arbitrarily. The next day is a date that crosses noon from the current date and time with noon as a reference. If it is determined that the scheduled date Dx is not the day following the current date and time Da, the empty bay setting unit 34 waits until the current date and time Da has passed "one day" (S120), and performs step S110 on the next day. Note that the empty bay setting unit 34 waits for the following steps for the target container ship Sx, and may perform the following steps for other container ships.

  When the scheduled date Dx is determined to be the day after the current date and time Da, the empty bay setting unit 34 determines the required number of empty bays 24 based on the number of loading containers Ca to be loaded on the container ship Sx. Is calculated (S130). The number of loading containers Ca to be loaded on the container ship Sx is input to the control system 31 together with the operation schedule.

  Next, the vacant bay setting unit 34 detects the number m of the vacant bays 24 existing at that time in the storage lane 20 arranged in the sea side area 15a (S140). The number m of the empty bays 24 present in the storage lane 20 at the present time can be detected by an instruction of a cargo handling operation to the portal crane 18 or an operation schedule of the container ship Sx. Regarding the empty bays 24 to be detected, the distance between the empty bays 24 adjacent in the X direction is more than the distance that can be simultaneously handled by a plurality of portal cranes 18.

  Next, the empty bay setting unit 34 determines whether the calculated number n is equal to or less than the detected number m (S150). In the present specification, “below” includes a case where the calculated number n is equal to the detected number m. If it is determined that the calculated number n is equal to or smaller than the detected number m (S150: YES), this step ends.

  On the other hand, if it is determined that the calculated number n is larger than the detected number m (S150: NO), the empty bay setting unit 34 selects the loading-only bay 22 to be the empty bay 24 (S160). Specifically, in this step, the empty bay setting unit 34 is scheduled to be loaded on the container ship Sx from the operation schedule of the container ship Sx in the bay 22 dedicated to loading and is stored. A container having a small number of storage containers Ca is selected as a target of the empty bay 24.

  Next, the instruction unit 36 of the control system 31 issues an instruction to the portal crane 18 to set the position Qx of the bay 22 dedicated to loading set in the empty bay setting unit 34 to the empty bay 24 (S170).

At this time, the loading container Ca stored at the position Qx is transferred to the container ship Sx due to a change in the schedule of the container ship Sx to be loaded, a change in the container ship Sx to be loaded, or circumstances. Has been left out for reasons such as the refusal of the loading of the cargo. Therefore, of the remaining loading containers Ca, the container container Sx to be loaded whose schedule is changed or the container container Sx to be loaded is changed is the changed container ship Sx or the changed container ship Sx. It is preferable that the storage position Px is set again based on the scheduled date Dx. In addition, a container refused to be loaded on the container ship Sx is specially provided in the storage lane 20 and stored in a dedicated bay for storing a container of such a type whose loading schedule is unknown. Is preferred.

  Next, the empty bay setting unit 34 counts that the number of empty bays 24 at the present time has increased according to the number of instructions issued to each of the portal cranes 18 from the instruction unit 36 (S180), and returns to step S130. The timing of counting that the number of available bays 24 at the present time has increased may be the time when the operation of forming the empty bays 24 by the portal crane 18 is actually completed.

  The above steps are performed until the calculated number n becomes equal to or smaller than the detected number m. In addition, the loading container Ca transported from the outside by the foreign transport vehicle 12 before the scheduled date Dx is stored in the empty bay 24 or the same dedicated loading bay 22 in which the container ship Sx to be loaded is loaded. The bays 22 dedicated to loading in which the loading containers Ca are stored up to the day before the scheduled date Dx may be counted as empty bays 24 if the number of stacks has room.

  As illustrated in FIG. 10, when the unique identification information Cx of the loading container Ca acquired by the information acquisition device 32 is input to the control system 31, the storage position setting unit 35 of the control system 31 The distribution information Lx associated with the identification information Cx stored in the internal storage device of the system 31 is read (S210).

  Next, the storage position setting unit 35 specifies the container ship Sx on which the target loading container Ca is to be loaded, based on the read distribution information Lx (S220).

  Next, the storage position setting unit 35, based on the specified container ship Sx, stores the loading container Ca loaded on the specified container ship Sx in the specified storage ship 20 in the storage lane 20 arranged in the seaside area 15a. It is determined whether there is a dedicated bay 22 (S230).

  If it is determined that there is a bay 22 dedicated to loading in which the loading containers Ca to be loaded on the specified container ship Sx are stored (S230: YES), the storage position setting unit 35 determines whether the target loading container Ca is to be loaded. The storage position Px is set in the bay 22 dedicated to loading (S240).

  Next, the instruction unit 36 of the control system 31 issues an instruction to store the target loading container Ca at the storage position Px set in the storage position setting unit 35 for the portal crane 18 (S250). The process ends.

  On the other hand, when it is determined that there is no bay 22 dedicated to loading in which the loading container Ca loaded in the specified container ship Sx is stored (S230: NO), the storage position setting unit 35 determines that the target loading is to be performed. The storage position Px of the container Ca is set to the empty bay 24 (S260).

  Next, the instruction unit 36 of the control system 31 issues an instruction to store the target loading container Ca at the storage position Px set in the storage position setting unit 35 for the portal crane 18 (S270). The process ends.

The above loading step will be described with reference to FIGS. In FIG. 2, the A bay and the D bay are empty bays 24, the B bay is a bay 22 dedicated to loading a loading container Ca transported from the foreign transport vehicle 12, and the C bay is loaded. Is a bay 22 dedicated to loading waiting for a berthing of the container ship Sx. In FIG. 3, A bay and D bay are bays 22 exclusively for loading while storing the loading container Ca transported from the foreign transport vehicle 12, and B bay is a cargo waiting for docking of the container ship Sx to be loaded. The bay 22 is dedicated to loading, and the C bay is an empty bay 24.

  As illustrated in FIG. 11, the method of storing the unloading container Cb in the storage lane 20 in the operation method of the container terminal 10 is different from the method of storing the loading container Ca in the storage lane 20 in comparison with the method of storing the empty bay 24. Are different from the order of the step of forming the instruction and the step of issuing the instruction.

  When the unique identification information Cx of the unloading container Cb acquired by the information acquisition device 32 is input to the control system 31, the storage position setting unit 35 of the control system 31 stores the identification information Cx in the internal storage device of the control system 31 in advance. The distribution information Lx associated with the identified identification information Cx is read (S310).

  Next, the storage position setting unit 35 specifies the scheduled date Dy of the target unloading container Cb based on the read distribution information Lx (S320). In this step, the scheduled date Dy is specified by using the regularity that the distribution information Lx has a peak on the execution day when the cargo handling operation of the portal crane 18 is performed in the same container C. The scheduled date Dy may be associated with the distribution information Lx in advance, or may be included in the distribution information Lx.

  Next, based on the specified scheduled date Dy, the storage position setting unit 35 sets the unloading-only bay 23 unified to the unloading container Cb of the specified scheduled date Dy in the storage lane 20 arranged in the land side area 15b. It is determined whether or not there is (S330).

  If it is determined that the unloading dedicated bay 23 is present in the unloading container Cb on the specified scheduled date Dy (S330: YES), the storage position setting unit 35 determines the storage position Px of the target unloading container Cb. The unloading-dedicated bay 23 is set (S440).

  Next, the instruction unit 36 of the control system 31 issues an instruction to store the target unloading container Cb at the storage position Px set in the storage position setting unit 35 for the portal crane 18 (S350). The process ends.

  On the other hand, if it is determined that there is no unified unloading bay 23 in the unloading container Cb on the specified scheduled date Dy (S330: NO), the empty bay setting unit 34 selects one of the unloading bays 23. The target of the empty bay 24 is set (S360). Specifically, in this step, the empty bay setting unit 34 determines that the unloading bay 23 that has exceeded the scheduled date Dy and has a small number of stored unloading containers Cb is an empty bay. 24 are set.

  Next, the instruction unit 36 of the control system 31 issues an instruction to the portal crane 18 to set the unloading bay 23 set in the empty bay setting unit 34 to the empty bay 24 (S370).

  At this time, the unloading container Cb stored in the unloading bay 23 which is the target of the empty bay 24 is to be stored in the upper part of another unloading bay 23 different from the storage bay. It is more preferable that the storage is stored in the upper part of another unloading bay 23 near the scheduled date Dx. In addition, the unloading container Cb stored in the unloading bay 23 which is the target of the empty bay 24 may be stored in an excess-only bay specially provided in the storage lane 20. The excess exclusive bay is an exclusive bay in which the container C whose scheduled date Dx has been exceeded is stored, and a plurality of storage bays may be provided in one storage lane 20.

  Next, the storage position setting unit 35 sets the storage position Px of the target unloading container Cb to the empty bay 24 (S380).

  Next, the instruction unit 36 of the control system 31 issues an instruction to store the target unloading container Cb at the storage position Px set in the storage position setting unit 35 for the portal crane 18 (S390). The process ends.

  According to the container terminal 10 described above, by unifying the status of the cargo handling work in the plurality of containers C stored in each of the bays 21 of the storage lane 20, it is possible to perform the cargo handling work on the yard transport vehicle 11 in the same bay 21. It is possible to avoid overlapping with the cargo handling work on the foreign transport vehicle 12. Thereby, it is advantageous to alleviate the congestion caused by the standby of the foreign transport vehicle 12 due to the overlap between the cargo handling operation on the premises transport vehicle 11 and the cargo handling operation on the foreign transport vehicle 12, and the cargo handling efficiency can be improved.

  In addition, by unifying the conditions of the cargo handling work in the plurality of containers C stored in the same bay 22 and grouping the containers C to be subjected to the cargo handling work in each situation, the portal crane 18 allows the bay 21 to be used. Reciprocating movement of the portal crane 18 that occurs when a plurality of containers C stored in a warehouse are loaded and unloaded. This is advantageous for shortening the time required for moving the portal crane 18 in the storage lane 20, and the cargo handling efficiency can be improved.

  The container terminal 10 loads a plurality of loading containers Ca stored in the loading bay 22 on the same container ship Sx. Therefore, when the loaded container ship Sx leaves the shore, it is emptied in bay units, and the vacant empty bay 24 is stored in the loading container Ca to be subsequently loaded on the container ship Sx berthing. Can be used for

  That is, by managing the loading container Ca for each bay 22 dedicated to loading, the bay 22 dedicated to loading and the empty bay 24 are sequentially replaced in the storage lane 20 according to the operation schedule of the container ship Sx. Become. This is advantageous for reducing the frequency of forming a large number of empty bays 24 each time the operation schedule of the container ship Sx is input, and the cargo handling efficiency can be improved.

  Further, the container terminal 10 calculates the required number n of empty bays 24 based on the number of loading containers Ca previously loaded on the same container ship Sx, and calculates the calculated number n of empty bays 24. It is a configuration to be prepared. Therefore, it is possible to reduce securing of the extra empty bay 24.

  In addition, the container terminal 10 has a configuration in which a necessary empty bay 24 is prepared on the day before the scheduled date Dx based on the scheduled date Dx of the loading container Ca to be loaded on the same container ship Sx in advance. is there. Therefore, the period during which the empty bay 24 exists in the storage lane 20 can be shortened.

  In this way, by appropriately securing the empty bay 24 according to the operation schedule of the container ship Sx, the container C due to the presence of the empty bay 24 that cannot be used for a long time in the storage lane 20 can be stored. This is advantageous for avoiding the reduction of the area, and the container yard 15 can be effectively used.

It is preferable that the date and time at which the instruction to form the vacant bay 24 for the portal crane 18 (S170) is made the day before the scheduled date Dx (the day when the container ship Sx berths in the operation schedule), and among the days before the scheduled date Dx It is more preferable at night when traffic of the foreign transport vehicle 12 is reduced. In this way, by setting the date and time when the portal crane 18 forms the empty bay 24 immediately before the scheduled date Dx, it is advantageous to avoid a decrease in the area where the container C can be stored. In addition, by limiting the date and time when the portal crane 18 forms the empty bay 24 to nighttime, the operation of forming the empty bay 24 can be performed without obstructing the cargo handling operation on the foreign transport vehicle 12.

  When a single storage lane 20 has a plurality of bays 22 dedicated to loading or a plurality of bays 23 dedicated to unloading in which a single storage lane 20 has unified loading and unloading work, these bays are connected by a plurality of portal cranes 18. Can be unloaded at the same time. Thereby, it is advantageous to reduce the waiting time of the loading and unloading work of the portal crane 18 in one storage lane 20, and the loading and unloading efficiency can be improved.

  The container terminal 10 is configured to predict the scheduled dates Dx and Dy as the status of the cargo handling work on the container C based on the physical distribution information Lx associated with the unique identification information Cx of the container C. In other words, the logistics information Lx is transported to the outside by the foreign transport vehicle 12 in the same container C, or is transported from the outside to the foreign transport vehicle 12 and stored using the regularity of the scheduled date and time. It was configured to predict Dx and Dy. In this way, by focusing on different regularities based on the distribution information Lx and utilizing the regularities, it is possible to manage a plurality of containers C stored in the storage lane 20 for each bay 21. Is advantageous, and the cargo handling efficiency can be improved.

  In the container terminal 10 of the embodiment, the plurality of storage lanes 20 are divided into a lane in which the loading container Ca is stored and a lane in which the unloading container Cb is stored. Therefore, in the same lane, the cargo handling work on the premises transport vehicle 11 and the cargo handling work on the foreign transport vehicle 12 do not occur at the same time. Can be divided. Thereby, it is advantageous to avoid a delay in the cargo handling work on the foreign transport vehicle 12 due to the cargo handling work on the premises transport vehicle 11, and it is possible to improve the cargo handling efficiency.

  As illustrated in FIG. 12, the container terminal 10 of the second embodiment is different from the first embodiment in that a bay 22 dedicated to loading and a bay 23 dedicated to unloading are mixed in one storage lane 20. Are different. As described above, when both the loading container Ca and the unloading container Cb are stored in one storage lane 20, in addition to the above-mentioned scheduled dates Dx and Dy of the foreign transport vehicle 12, the on-premise transport vehicle 11 It is desirable to consider the scheduled date of the cargo handling work of the portal crane 18 (or the berthing date of the container ship Sx). In other words, it is desirable to make the time zone during which the premises transport vehicle 11 enters the storage lane 20 different from the time zone during which the foreign transport vehicle 12 enters.

  Specifically, a plurality of loading containers Ca stored in the bay 22 dedicated to loading in the A bay are subjected to the loading and unloading work from the foreign transport vehicle 12 transported from the outside by the portal crane 18 to the storage lane 20. The scheduled date D8 is the same. Further, the plurality of loading containers Ca stored in the bay 22 dedicated to loading in the A bay are loaded on the premises transport vehicle 11 by the portal crane 18 and are scheduled to be loaded on the container ship Sx on the same date D9. is there. The plurality of unloading containers Cb stored in the unloading bay 23 of the B bay are loaded on the foreign transport vehicle 12 by the portal crane 18 and transported outside the container terminal 10 at the same scheduled date D10. In addition, for the plurality of unloading containers Cb stored in the unloading bay 23 of the B bay, the loading / unloading operation from the yard transport vehicle 11 transported from the container ship Sx to the storage lane 20 by the portal crane 18 is performed. The scheduled date D11 is the same. The plurality of unloading containers Cb stored in the unloading bay 23 of the D bay are loaded on the foreign transport vehicle 12 by the portal crane 18 and transported outside the container terminal 10 at the same scheduled date D12. In addition, for the plurality of unloading containers Cb stored in the unloading bay 23 of the D bay, the loading / unloading operation from the yard transport vehicle 11 transported from the container ship Sx to the storage lane 20 by the portal crane 18 is performed. The scheduled date D13 is the same.

  As described above, when the bay 22 dedicated to loading and the bay 23 dedicated to unloading are mixed in one storage lane 20, the scheduled dates Dx and Dy of the loading / unloading operation on the alien transport vehicle 12 and the loading / unloading operation on the private transport vehicle 11 are performed. Set a different date from the scheduled date of work. Therefore, it is possible to avoid the overlap between the time zone in which the local transport vehicle 11 enters the storage lane 20 and the time zone in which the foreign transport vehicle 12 enters. As a result, even if the lanes are not distinguished, the cargo handling work on the premises transport vehicle 11 and the cargo handling work on the foreign transport vehicle 12 do not occur at the same time in the same lane. The cargo handling work for the vehicle 12 can be completely separated.
