Description

  The present invention relates to a container yard and a container yard control method in which at least a part of the operation of a portal crane is automated to handle a container, and more particularly, the portal crane is more efficient than a local chassis and an external chassis. The present invention relates to a container yard that can deliver a container and a container yard control method.

  Various automated container yards have been proposed in which container handling is performed using an automated guided vehicle or an automated portal crane (see, for example, Patent Document 1).

  Patent Document 1 proposes a container yard in which a cargo handling lane in which a chassis that transfers containers runs and a traffic lane that only allows the chassis to pass are arranged in order along a storage area in which containers are stored.

  The container yard described in Patent Document 1 detects that the chassis has arrived at a predetermined position in the cargo handling lane by a camera or sensor installed on the leg portion of the portal crane, and uses this information for the cargo handling work in the container yard. The data is transmitted to an automatic driving system that controls automation (hereinafter sometimes referred to as a host system). The host system automatically displays the container and chassis images to be handled on the monitor in the remote control room. The crane operator checks the monitor and remotely operates the portal crane to mount the container on the chassis.

  Within the container yard, there are a plurality of premises chassis that transport containers between the container ship berthed at the container yard and the storage area, and a plurality of foreign chassis that transport containers between the storage area and the outside of the container yard. Running. The yard chassis and the foreign chassis enter the cargo handling lane one after another in a turbulent state.

  Sensing equipment for transmitting identification information for distinguishing multiple local chassis, position information indicating the position in the container yard, and information such as whether or not a container is mounted to the host system. Often installed. The sensing device is composed of a communication device and a sensor. With this sensing device, the host system was able to distinguish between a plurality of local chassis and accurately grasp each position.

  On the other hand, most of the sensing equipment is not mounted on the foreign chassis that mainly run on public roads and transport containers. Since the foreign chassis does not have a sensing device, it is difficult for the host system to accurately distinguish the plurality of foreign chassis. In addition, it was difficult for the host system to accurately grasp the position of the foreign chassis.

  In the container yard described in Patent Document 1, a foreign chassis is identified by a sensor or a camera installed on a leg portion of a portal crane. As a result, the accuracy of identifying foreign chassis was low.

  For this reason, for example, due to the influence of another chassis traveling in the traveling lane, the sensor or the like may erroneously detect the arrival of the foreign chassis even though the foreign chassis has not arrived under the portal crane. In some cases, an image was displayed on the monitor in the remote control room even though no foreign chassis was present under the container held by the portal crane. The host system does not proceed to the next control step until the operation of mounting the container on the foreign chassis is completed. Since the entire host system is stopped, there has been a problem that the cargo handling efficiency is remarkably lowered.

  For example, since a foreign chassis was mistakenly identified, there was a problem that the container was mounted on a foreign chassis different from the foreign chassis on which the container was originally mounted.

  For example, when an identification number or the like of a foreign chassis entering the lower part of a portal crane is photographed by a camera, the identification number or the like may not be photographed if another chassis passes through the traveling lane. In such a case, it was necessary to move the portal crane and re-photograph the identification number. Since the movement of the portal crane is an operation that is not originally planned by the host system, the entire host system stops. This has caused a significant drop in cargo handling efficiency.

  As described above, in the automated container yard, the presence of a foreign chassis has been a major disturbance factor in automating cargo handling operations by the host system. In this specification, the disturbance means that the orderly operating state of the host system is disturbed when the host system performs the control of automatically handling the portal crane and handling the container.

JP 2005-239343 A

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a container yard and a container yard control method by which a portal crane can efficiently deliver a container to a local chassis and an external chassis. It is to provide.

  The container yard of the present invention that achieves the above-mentioned object automatically determines the storage area in which the container is stored, the portal crane that travels along the storage area, and the destination of the portal crane. An automatic operation system that performs control, wherein a yard chassis that transports the container between a container ship berthing to the container yard and the storage area, and the storage area and the outside of the container yard A lane for transporting the container between the premises, a premises chassis lane arranged along the storage area on which the premises chassis travels, and a lane for the premises chassis separate from the lane for the premises chassis And an external chassis lane disposed along the external chassis.

  The container yard control method of the present invention is a container yard control method comprising: a portal crane that travels along a storage area in which containers are stored; and an automatic operation system that automatically travels the portal crane. A premises chassis lane is arranged along the storage area, the premises chassis is run along the premises chassis lane, and the container is transferred between the storage area and the premises chassis by the portal crane. The alien chassis lane is arranged along the premises chassis lane, the alien chassis is driven along the alien chassis lane, and the portal crane is used between the storage area and the alien chassis. The container is delivered.

According to the present invention, the premises chassis lane in which the premises chassis travel and the alien chassis lane in which the alien chassis travel are provided separately, so that the premises chassis can move without being affected by the alien chassis. it can. Since the foreign chassis is unlikely to be a disturbance factor in the automation of the cargo handling operation, it is advantageous to automate the cargo handling operation without reducing the cargo handling efficiency.

  The premises chassis lane can be arranged between the storage area and the external chassis lane. Since the container handled by the portal crane does not cross the foreign chassis lane, it is possible to avoid the situation where the cargo handling work of the portal crane is interrupted due to the passage of the foreign chassis. It is advantageous for improving the cargo handling efficiency. Further, since the container does not pass over the foreign chassis, it is advantageous to improve the safety of the driver of the foreign chassis.

  The local chassis can be configured to include a sensing device that transmits identification information for identifying each local chassis and position information indicating the position of the local chassis in the container yard to the automatic driving system.

  Since the automatic operation system can accurately grasp the identification information and position of the campus chassis, it is advantageous to efficiently deliver containers between the portal crane and the campus chassis.

  The foreign chassis lane is configured to include a cargo handling area that transfers containers to and from a portal crane by stopping the chassis and an identification machine that identifies the foreign chassis that are stopped in the cargo handling area. can do.

  Since the foreign chassis that delivers the container can be identified by an identification device installed in the foreign chassis lane, it is advantageous to perform the presence / absence and identification of the foreign chassis with high accuracy.

  The discriminator can be composed of a camera that photographs the license plate of the foreign chassis entering the cargo handling area.

  Since the license plate can be reliably photographed when the foreign chassis enters the cargo handling area, it is advantageous to accurately identify the foreign chassis.

It is explanatory drawing which illustrates the container yard of this invention with a plane. It is explanatory drawing which illustrates the container yard of FIG. 1 with an AA end surface. It is explanatory drawing which illustrates a cargo handling exclusive area. It is explanatory drawing which illustrates the modification of the container yard of FIG.

  Hereinafter, a container yard and a container yard control method of the present invention will be described based on the embodiments shown in the drawings. In the drawing, the traveling direction of the portal crane is indicated by an arrow y, the transverse direction that intersects the traveling direction at a right angle is indicated by an arrow x, and the vertical direction is indicated by an arrow z.

  As illustrated in FIGS. 1 and 2, the container yard 1 of the present invention includes a storage area 3 in which a plurality of containers 2 are stored, and a portal crane 4 that travels along the storage area 3. . On the side of the storage area 3 in the transverse direction x, a premises chassis lane 6 on which the premises chassis 5 travels is arranged. The premises chassis lane 6 is arranged in a state of being adjacent to and parallel to the storage area 3 from one end to the other end of the storage area 3.

  An external chassis lane 8 on which the external chassis 7 travels is arranged on the side of the local chassis lane 6 in the transverse direction x. The foreign chassis lane 8 is disposed adjacent to and parallel to the local chassis lane 6. The local chassis lane 6 and the external chassis lane 8 are arranged along the longitudinal direction (traveling direction y) of the storage area 3. The local chassis lane 6 and the external chassis lane 8 are provided independently without overlapping each other. The in-house chassis lane 6 is disposed between the storage area 3 and the external chassis lane 8.

  In the container yard 1, a plurality of such storage areas 3, premises chassis lanes 6 and foreign chassis lanes 8 are arranged. In addition, an automatic operation system (hereinafter sometimes referred to as a host system) 9 that controls automatic operation of the portal crane 4 is installed in a management ridge or the like in the container yard 1. In this management building, a monitor for displaying an image of the container 2 suspended by the portal crane 4 and a controller for remotely operating the portal crane 4 are arranged. As shown by a broken line in FIG. 1, communication between the portal crane 4 and the host system 9 is performed wirelessly or by wire.

  The premises chassis 5 transports the container 2 between the container ship berthed at the container yard 1 and the storage area 3. The on-site chassis 5 is a container transport chassis managed by the operating company of the container yard 1 and is driven by a driver belonging to the operating company.

  The premises chassis 5 is a sensing device that directly or indirectly transmits identification information for distinguishing a plurality of premises chassis 5 and position information indicating the current position of the premises chassis 5 in the container yard 1 to the host system 9. 10 is provided. As indicated by a broken line in FIG. 1, communication between the local chassis 5 and the host system 9 is performed wirelessly or by wire.

  The sensing device 10 stores, for example, a storage mechanism that stores identification information such as a unique number assigned to each of the plurality of local chassis 5, a position measurement mechanism that measures the position of the local chassis 5, and the identification information and position information to the host system 9. A communication mechanism that transmits or receives an instruction from the host system 9 and a display mechanism that displays an instruction from the host system 9 to allow the driver to confirm the information are selectively combined. The position measuring mechanism may be configured by a satellite positioning system such as GPS, or a device that arranges a plurality of transponders in the container yard 1 and measures the relative position of the transponders using ultrasonic waves or radio waves. it can. The premises chassis 5 is not limited to a manned chassis operated by a driver, and may be constituted by an automatic guided vehicle such as AGV.

  The foreign chassis 7 carries the container 2 between the outside of the container yard 1 and the storage area 3. The foreign chassis 7 is a container transport chassis managed by an external transport company or the like, and is driven by a driver belonging to the transport company or the like. Since the foreign chassis 7 mainly transports the container 2 on public roads, it is general that the foreign chassis 7 does not have equipment and configuration necessary for a specific container yard. For this reason, most of the foreign chassis 7 does not include the sensing device 10. However, in the present invention, the external chassis 7 is not limited to a configuration that does not include the sensing device 10, and may have a configuration that includes the sensing device 10.

  The premises chassis 5 travels on the premises chassis lane 6, and the foreign chassis 7 travels on the alien chassis lane 8. The portal crane 4 travels along a travel path 11 formed in parallel with the storage area 3. In this embodiment, the portal crane 4 travels in a state of straddling the storage area 3, the on-site chassis lane 6, and the external chassis lane 8. That is, the storage area 3, the on-site chassis lane 6, and the external chassis lane 8 are arranged between the pair of traveling paths 11 of the portal crane 4.

As illustrated in FIG. 2, the portal crane 4 includes a pair of leg portions 12 extending in the vertical direction z, a beam portion 13 that is a horizontal member connecting the upper ends of the pair of leg portions 12, and the beam portion 13. The trolley 14 is arranged so as to be movable in the transverse direction x, and the spreader 15 is suspended from the trolley 14 and lifts the container 2.

  Next, cargo handling work in the container yard 1 will be described. When transporting the container 2 from the storage area 3 to the container ship, the host system 9 first determines the container 2 to be handled, and automatically moves the portal crane 4 toward the container 2 to be handled as the destination. Let it run. After the movement of the portal crane 4 is completed, the trolley 14 is traversed and the spreader 15 is lowered toward the container 2 to be handled. After the connection between the container 2 and the spreader 15 is completed, the spreader 15 is wound up to a predetermined height. When delivering the container 2 to be handled to the premises chassis 5, the container 2 is moved above the premises chassis lane 6 by the traversing of the trolley 14 and waits. The cargo handling operation so far by the portal crane 4 is performed by automatic operation by the host system 9.

  In parallel with the automatic operation of the portal crane 4, the host system 9 notifies the target premises chassis 5 of the position of the container 2 to be handled. The driver of the premises chassis 5 travels on the premises chassis lane 6 toward the container 2 to be handled as a destination. In the vicinity of the container 2 to be handled, the portal crane 4 is carrying out the cargo handling work, but the local chassis 5 stands by at a position on the side of the container 2 to be handled.

  The premises chassis 5 measures its own position by a position measuring mechanism constituting the sensing device 10. The local chassis 5 transmits the identification information together with the acquired position information to the host system 9. The sensing device 10 may be configured to transmit position information and the like to the upper system 9 when the local chassis 5 arrives at the destination, and sequentially transmit the positional information and the like to the upper system 9 even during movement of the local chassis 5. You may make it the structure which transmits.

  The host system 9 determines from the identification information and the position information transmitted from the campus chassis 5 whether or not the predetermined chassis 5 is waiting below the predetermined portal crane 4. When a predetermined local chassis 5 is waiting below a predetermined portal crane 4, the host system 9 determines that preparation for delivery has been completed. If delivery preparation is not complete, wait until completion.

  After the preparation for delivery is completed, the host system 9 photographs the container 2 and the premises chassis 5 with a camera installed on the portal crane 4 and displays this image on the monitor of the management building. The crane operator lowers the container 2 by remote control using the controller while confirming the images of the container 2 and the campus chassis 5 displayed on the monitor.

  After placing the container 2 on the premises chassis 5, the crane operator separates the spreader 15 from the container 2 and raises it. When the spreader 15 rises to a predetermined height, the remote operation by the crane operator is finished. The portal crane 4 is controlled by the host system 9 and starts automatic operation for the next container 2 to be handled.

  When the remote operation by the crane operator is completed, the host system 9 notifies the driver of the premises chassis 5 that the delivery work of the container 2 has been completed. For example, a message indicating that the delivery work has been completed is displayed on the display mechanism constituting the sensing device 10. The driver of the premises chassis 5 transports the delivered container 2 to a predetermined destination. Thereafter, the container 2 is loaded on a container ship.

When the container 2 is transported from the container ship to the storage area 3, first, the premises chassis 5 on which the container 2 is mounted travels to a predetermined position instructed by the host system 9. In parallel, the host system 9 moves the portal crane 4 to a predetermined position by automatic operation, and moves the spreader 15 in advance above the premises chassis lane 6 in advance. When the predetermined local chassis 5 arrives below the predetermined portal crane 4, the host system 9 determines that the preparation for delivery has been completed. Thereafter, the host system 9 switches the operation of the portal crane 4 to the remote operation by the crane operator. The container 2 is lifted by the spreader 15, and when the spreader 15 is raised to a predetermined height, the remote operation is finished. By repeating the above, the container 2 is transported between the storage area 3 and the container ship.

  When the container 2 to be handled is transferred from the storage area 3 to the foreign chassis 7, the driver of the foreign chassis 7 is first instructed to receive the container 2 during the entry procedure to the container yard 1. The driver of the foreign chassis 7 travels on the foreign chassis lane 8 toward the container 2 to be handled.

  On the leg 12 of the portal crane 4 on the side close to the foreign chassis lane 8, a camera for photographing the license plate of the foreign chassis 7 traveling on the foreign chassis lane 8 is installed. The portal crane 4 acquires, in advance, an image of a license plate or the like of the external chassis 7 traveling in the external chassis lane 8 while performing a cargo handling operation on the local chassis 5, for example. The host system 9 identifies the foreign chassis 7 based on the image sent from the portal crane 4 and determines whether or not it is a predetermined foreign chassis 7. Further, based on information from the sensors installed on the legs 12, the host system 9 determines whether or not the external chassis 7 is stopped at a predetermined position.

  The method of identifying the foreign chassis 7 is not limited to photographing such as a license plate. For example, when entering the container yard 1, the identification board is handed over to the driver of the foreign chassis 7, and the identification board is presented in a predetermined place such as the inside of the windshield. You may make it the structure which image | photographs this identification board. For example, the RFID may be handed over to the driver of the external chassis 7 during the entry procedure to the container yard 1 and detected by a sensor installed on the portal crane 4.

  The foreign chassis 7 travels in the immediate vicinity of the camera or sensor installed on the portal crane 4, which is advantageous for improving the detection accuracy of the camera or sensor. In addition, since no other chassis passes between the camera or sensor and the external chassis 7, it is possible to avoid erroneously detecting the identification number of the external chassis 7 or being unable to detect it in the first place.

  The host system 9 determines that the preparation of the foreign chassis 7 has been completed when the predetermined foreign chassis 7 has arrived at a predetermined position. Thereafter, the host system 9 causes the portal crane 4 to travel toward the container 2 to be handled, and moves the container 2 to above the foreign chassis 7 waiting in the foreign chassis lane 8. The cargo handling operation so far by the portal crane 4 is performed by automatic operation by the host system 9.

  The host system 9 confirms again that the external chassis 7 is waiting below the predetermined portal crane 4 and determines that the preparation for delivery is completed when the confirmation is obtained. After the preparation for delivery is completed, the host system 9 switches the operation of the gate crane 4 to the remote operation by the crane operator.

  After placing the container 2 on the foreign chassis 7, the crane operator separates the spreader 15 from the container 2 and raises it. When the spreader 15 rises to a predetermined height, the remote operation by the crane operator ends. When the remote operation by the crane operator is completed, the host system 9 notifies the driver of the external chassis 7 that the delivery work of the container 2 has been completed by a speaker or the like installed on the leg 12 of the portal crane 4. To do. The driver of the foreign chassis 7 transports the delivered container 2 to a predetermined destination outside the container yard 1.

  When the container 2 is transported from the outside of the container yard 1 to the storage area 3, first, the foreign chassis 7 loaded with the container 2 travels to the place designated during the entrance procedure. When the predetermined foreign chassis 7 arrives at the predetermined location, the host system 9 determines that the preparation of the foreign chassis 7 has been completed.

  Thereafter, the host system 9 moves the spreader 15 of the portal crane 4 above the external chassis 7 and switches the operation of the portal crane 4 to the remote operation. The container 2 is lifted by the spreader 15, and when the spreader 15 is raised to a predetermined height, the remote operation is finished. After that, the trolley 14 of the portal crane 4 moves in the transverse direction x while holding the container 2, and the portal crane 4 moves in the traveling direction y, so that the container 4 is placed at a predetermined position in the storage area 3. Stored. The container 2 is transported between the outside of the container yard 1 and the storage area 3 by repeating the above.

  Since the delivery of the container 2 to the premises chassis 5 is prioritized over the foreign chassis 7, the time during which the container ship berths in the container yard 1 can be shortened. It is advantageous to accept more container ships.

  Since the premises chassis lane 6 on which the premises chassis 5 travels and the alien chassis lane 8 on which the exterior chassis 7 travels are provided separately, the alien chassis 7 is stopped at the wrong place. However, the local chassis 5 can move along the storage area 3 without being affected by this, and can handle the container 2.

  Further, since the host system 9 performs the cargo handling work of the portal crane 4 on the foreign chassis 7 only after the preparation of the foreign chassis 7 is completed, the portal crane is not used unless a predetermined foreign chassis 7 arrives at a predetermined place. 4 can continue the cargo handling operation for the premises chassis 5. That is, the automatic operation of the cargo handling work by the host system 9 is hardly affected by the external chassis 7. Since the external chassis 7 is unlikely to be a disturbance factor in the automatic operation of the cargo handling operation, it is advantageous to realize the automatic operation of the portal crane 4 without reducing the cargo handling efficiency.

  Even if a plurality of local chassis 5 and foreign chassis 7 are intruded into one storage area 3, automatic operation can be efficiently performed without confusing the host system 9.

  In the above-described embodiment, the portal crane 4 starts the cargo handling operation of the container 2 after confirming that the preparation of the foreign chassis 7 is completed, but the present invention is not limited to this. In parallel with the preparation of the foreign chassis 7, the cargo handling of the portal crane 4 for the foreign chassis 7 may be prepared.

  Even if the local chassis 5 does not have the sensing device 10, the local chassis 5 can be identified by a camera or the like installed on the portal crane 4 and its position can be detected. However, it is advantageous that the local chassis 5 has the sensing device 10 because the accuracy of detecting the identification and position of the local chassis 5 is improved.

  In preparation for an accident in which the container 2 being handled is dropped by the portal crane 4, it is prohibited for the manned premises chassis 5 and the foreign chassis 7 to pass under the container 2. In the embodiment illustrated in FIGS. 1 and 2, the foreign chassis lane 8 is located outside, so that the container 2 does not cross over the foreign chassis lane 8. The portal crane 4 is advantageous in improving the cargo handling efficiency because it is not necessary to interrupt the cargo handling operation in accordance with the passage of the external chassis 7. Moreover, since the container 2 does not cross over the foreign chassis 7, it is advantageous for improving safety.

  The container 2 sometimes crosses above the premises chassis lane 6 arranged inside. When the display mechanism is installed in the premises chassis 5 as a part of the sensing device 10, when the container 2 crosses the lane 6 for the premises chassis, the host system 9 stops driving to the driver. Can be instructed. Since the campus chassis 5 stops, the portal crane 4 does not need to stop the cargo handling operation of the container 2. Since priority can be given to the cargo handling work by the portal crane 4, it is advantageous for improving the cargo handling efficiency. Further, since it is possible to prevent the local chassis 5 from passing below the container 2, it is advantageous for improving the safety of the driver of the local chassis 5.

  Even if the sensing device 10 is not installed in the premises chassis 5, the driver of the premises chassis 5 is a driver belonging to the operating company of the container yard 1. It can be improved. For example, when the spreader 15 lifts the container 2 when passing under the portal crane 4, it is easy to thoroughly follow an operation rule such as waiting.

  In the embodiment illustrated in FIG. 1 and the like, the storage area 3, the on-site chassis lane 6, and the external chassis lane 8 are arranged in this order, but the present invention is not limited to this. The storage area 3, the external chassis lane 8, and the local chassis lane 6 can be arranged in this order so that the external chassis lane 8 is adjacent to the storage area 3. Even in this configuration, since the local chassis 5 and the external chassis 7 travel on different lanes, the external chassis 7 is unlikely to be a disturbance factor. This is advantageous for efficient automatic operation by the host system 9.

  When the on-site chassis 5 waiting for the delivery work or the delivery of the container 2 is stopped in front, the rear on-site chassis 5 temporarily travels on the foreign chassis lane 8 and moves to the front on-site chassis 5. It can be configured to overtake. Similarly, the rear external chassis 7 can temporarily travel on the local chassis lane 6 to overtake the front external chassis 7. When a plurality of portal cranes 4 are arranged in one storage area 3 and are simultaneously performing a cargo handling operation, the number of chassis that are stopped in the on-site chassis lane 6 and the external chassis lane 8 increases. The configuration that overtakes the front chassis allows the rear local chassis 5 and the foreign chassis 7 to move to the target location in a shorter time, which is advantageous in improving the cargo handling efficiency.

  As illustrated in FIG. 3, a cargo handling exclusive area 16 can be formed in a part of the foreign chassis lane 8. The cargo handling area 16 is an area where the foreign chassis 7 stops and the container 2 is transferred to and from the portal crane 4. The foreign chassis 7 delivers the container 2 only in the cargo handling area 16 and does not deliver the container 2 in other parts. One or a plurality of cargo handling dedicated areas 16 can be arranged for one storage area 3.

  It is desirable to configure the road surface of the cargo handling exclusive area 16 so that it can be visually distinguished from other parts of the foreign chassis lane 8 by painting or the like. With this configuration, the visibility of the cargo handling exclusive area 16 by the driver of the external chassis 7 can be improved.

  An identification machine 17 for identifying the foreign chassis 7 entering the cargo handling area 16 is fixed in the cargo handling area 16. The identification machine 17 is a position that is in front of the traveling direction of the foreign chassis 7 in the cargo handling exclusive area 16 and can be installed outside the premises chassis lane 5.

The discriminator 17 can be constituted by a camera that photographs, for example, a license plate of the external chassis 7 or an identification board arranged inside the windshield. Identification information for identifying the foreign chassis 7 is acquired by the classifier 17 and transmitted to the host system 9 by radio or wire. The host system 9 compares the identification information of the foreign chassis 7 acquired during the entry procedure to the container yard 1 with the identification information transmitted from the identification machine 17, and the foreign system stopped in the cargo handling area 16. It is determined whether the chassis 7 is a predetermined foreign chassis 7 or not.

  The discriminator 17 is not limited to a camera and may be any device that can discriminate the foreign chassis 7. For example, a transmitter that transmits a specific signal to the external chassis 7 during the admission procedure may be installed, and a receiver that receives this signal may be installed as the identifier 17.

  In this embodiment, the discriminator 17 is fixed on the foreign chassis lane 8. Regardless of the position of the gate-type crane 4 that repeatedly moves in accordance with the cargo handling work, the foreign chassis 7 entering the cargo handling area 16 can be reliably identified. Further, since the discriminator 17 is fixed to the foreign chassis lane 8, it is not easily affected by vibration caused by the traveling of the portal crane 4. Therefore, it is advantageous to improve the accuracy in identifying the external chassis 7 as compared with the configuration in which the classifier 17 such as a camera is installed on the leg portion 12 of the portal crane 4.

  Since the container 2 is transferred between the foreign chassis 7 and the portal crane 4 only in the cargo handling area 16 which is a limited place, the foreign chassis 7 has a wrong stop position or there is an error in this stop position. It is advantageous to avoid the situation that occurs. Since the host system 9 can know the position of the foreign chassis 7 from the position of the cargo handling dedicated area 16, the accuracy of the position information of the foreign chassis 7 is improved.

  A traffic light 18 can be installed on the front side of the cargo handling area 16 to notify the driver of the foreign chassis 7 that the exit from the cargo handling area 16 is permitted or prohibited. According to this configuration, it is possible to prevent an accident in which the foreign chassis 7 that has stopped in the cargo handling area 16 exits from the cargo handling area 16 even during cargo handling work. It is advantageous to improve safety. In addition, after the cargo handling operation is completed, the foreign chassis 7 can be promptly moved out, which is advantageous for improving the cargo handling efficiency.

  A traffic light 19 can be installed behind the cargo handling area 16 to notify the driver of the foreign chassis 7 that the entry into the cargo handling area 16 is permitted or prohibited. It is possible to prevent an accident in which the subsequent foreign chassis 7 enters the cargo handling area 16 during the cargo handling work. It is advantageous to improve safety.

  A display device 20 that displays the progress of the cargo handling work by the portal crane 4 can be installed in front of the cargo handling area 16. As described above, in order to receive many container ships, it is desirable that the portal crane 4 prioritizes the cargo handling work on the premises chassis 5 over the foreign chassis 7. In this case, there is a possibility that the waiting time of the foreign chassis 7 waiting in the cargo handling exclusive area 16 becomes long. It is desirable to install a display device 20 that informs the progress of the cargo handling work of the portal crane 4 so that the driver of the waiting external chassis 7 does not get off the external chassis 7 to see the situation. Safety can be improved by installing the display device 20.

  When the foreign chassis 7 is stopped in the wrong cargo handling exclusive area 16, the host system 9 can notify the driver of the foreign chassis 7 using the display device 20. By installing the display device 20, it is possible to avoid a situation where the foreign chassis 7 waits for a long time at an incorrect position, which is advantageous in improving the cargo handling efficiency.

  The identification device 17, the traffic lights 18, 19 or the display device 20 installed in the cargo handling area 16 may be arranged inside the cargo handling area 16 or outside the cargo handling area 16. The discriminator 17 and the like are desirably arranged at least inside the foreign chassis lane 8.

  As illustrated by a one-dot chain line in FIG. 1, it is desirable that the cargo handling position P in the cargo handling dedicated area 16 is set in a state where the center position coincides with one of the rows of containers 2 placed in the storage area 3. When handling containers 2 in a row whose center position coincides with at least the loading position P, the portal crane 4 does not need to move in the traveling direction y while holding the containers 2. It is advantageous for improving the cargo handling efficiency. As illustrated in FIG. 2, it is desirable to provide a stop line 21 in the cargo handling area 16 in order to stop the foreign chassis 7 at an accurate position in the cargo handling area 16.

  As illustrated in FIG. 4, the portal crane 4 can be configured to include a sliding beam portion 22 extending from the beam portion 13 in the transverse direction x. The portal crane 4 is arranged in a state of straddling only the storage area 3. The premises chassis lane 6 and the outboard chassis lane 8 are disposed outside the pair of legs 12 of the portal crane 4. The sliding beam portion 22 is configured to have a length that reaches above the local chassis lane 6 and the external chassis lane 8.

  In this embodiment, the portal crane 4 traverses the trolley 14 from the beam portion 13 toward the sliding beam portion 22 and conveys the container 2 to above the premises chassis lane 6 or the foreign chassis lane 8.

  According to this configuration, the present invention can be applied even when there is no space for providing the local chassis lane 6 and the external chassis lane 8 below the portal crane 4. When the traveling path 11 of the portal crane 4 is composed of rails, the existing rails can be used as they are.

  Further, in addition to the storage area 3, the premises chassis lane 6 may be arranged between the pair of legs 12 of the portal crane 4. F
