Description

  The present invention relates to a container delivery method and a delivery device for delivering a container between a local chassis that transports the container in a container yard of a container terminal and an exogenous chassis that transports the container to the land. The present invention relates to a container delivery method and a delivery apparatus suitable for a container terminal having a switching area.

  The container terminal is a facility that serves as a point of contact between different means of transportation between sea and land. Its main function is to load and unload containers between these different means of transportation. For this reason, a container yard for temporarily storing containers waiting for loading and unloading is provided. In other words, the container yard stores containers that are loaded into or unloaded from a container ship berthed at the quay and loaded into or from a chassis for land transportation. .

  By the way, in order to rationalize container handling work for loading and unloading of containers in a container yard, a labor saving or unmanned operation system has been developed in a container terminal. This can be done by loading containers onto the container ship, loading and unloading containers from the container ship, transporting the container to the storage position by traveling inside the container yard, or transferring the container at the storage position to the container Containers can be transported to the chassis of a ship or land transport by loading a container at the storage position on the chassis, and a yard crane for loading and unloading containers from the chassis can be operated automatically or remotely. It is a system that tries to unmanned the yard.

  In order to promote such labor-saving and unmanned operations, automation of container yard operation plans, etc., and to improve efficiency, a container terminal system has been proposed that prevents the entry of external vehicles into the container yard ( Patent Document 1). This container terminal system includes a container crane that handles containers on a ship, and a container yard that can store and store containers. The container terminal system handles containers between ships and land transport vehicles. A plurality of transfer cranes that have a gate-shaped mainframe and can be loaded or unloaded automatically or manually, and between the container crane and the transfer crane, and a flat container in the container yard The AGV is installed in the vicinity of the boundary between the container yard and the outside, and the container is transferred manually or partially automatically between the AGV in the container yard and the outside land transport vehicle. Perform delivery crane and container In which de and land transport vehicle is configured to include a boundary indicia provided on the boundary between the drivable externally.

  In addition, in order to make the container transportation at the container terminal smoother and safer, the container trailer waits in the trailer arrival and departure area and transfers containers to and from the container transfer machine in the specified order. A container terminal has been proposed (Patent Document 2).

  Also, a container yard where containers are stacked in multiple stages to reduce costs by eliminating the need for a container storage building and to improve space utilization efficiency without bending the track of the transport carriage A container crane capable of loading and unloading containers on a container ship, a sea-side transport cart that can move along the sea-side traveling rail and the sea-side traversing rail, and can deliver containers to and from the container crane, and land-side traveling Between the land-side transport cart that can move along the rail and the land-side traverse rail, the transfer machine that transfers containers between the land-side transport cart and the chassis, and the sea-side transport cart and the land-side transport cart A container-type transfer crane having a portal-type transfer crane that can deliver containers in a yard and can be arranged by stacking containers in multiple stages between yard traverse rails Le is disclosed (Patent Document 3).

Patent No. 2892606 JP 09-156769 A JP 11-079409

  When the container yard is unmanned, an automated guided vehicle (AGV) travels in the container yard and transports the container, so that the unmanned transport cart does not interfere with the operation. Of course, it is necessary to prevent workers and the like from entering the container yard. In addition, the delivery of the container between the foreign chassis is performed in a dedicated delivery area, and a delivery crane or a transfer machine is used as in the container terminal disclosed in Patent Literature 1 and Patent Literature 3.

  In the delivery area, the company waits for delivery of the unloading container containing the imported cargo to be transported to the shipper, etc., and loading into the container ship between the on-site chassis that transports the container in the container yard and the foreign chassis. Therefore, a delivery container that contains export cargo temporarily stored in the container yard is delivered. The carry-in container may be transferred to the local chassis in the order in which the foreign chassis came. However, in the carry-out container, the storage position in the container yard, the status of the cargo handling work, etc. are not constant, and it is difficult to deliver the carry-out container in the order of receipt of the visiting foreign chassis. As described above, since the delivery state of the carry-in container and the carry-out container is different, the delivery area is preferably separated into a carry-in area dedicated to the carry-in container and a carry-out area dedicated to the carry-out container.

  As described above, in the carry-out area, containers cannot be delivered to the foreign chassis in the order of arrival. Therefore, as disclosed in Patent Document 2, a standby area for the foreign chassis is provided and the containers are transported from the container yard. In a state where preparations for reloading are complete, instructions are given to the relevant foreign chassis, and the foreign chassis that receives the instructions travels from the standby location to the switching point where the container transfer machine is located, and reloads the container. Become. Further, in order to shorten the standby time at the standby place, it is necessary to provide a large number of switching points.

  However, the foreign chassis does not always stand by for carrying out, and there is a so-called peak time in the standby state. If the number of switching points corresponding to this peak time is arranged, there will be an excess of switching points other than at the peak time, and there is a possibility that the equipment such as a container transfer machine provided at the switching point will be wasted. is there. On the other hand, if the foreign chassis corresponding to the ready container is called up to the switching point, the standby time of the foreign chassis may be increased. In addition, it is necessary to provide a standby place, and the standby place requires an area that matches the peak time of the visit of the foreign chassis.

  Therefore, the present invention shortens the standby time of the visiting foreign chassis as much as possible, does not need to provide a large number of switching points, and does not need to secure a large area for standby of the foreign chassis. It is an object of the present invention to provide a container delivery method and a delivery device with a foreign chassis.

  As a technical means for achieving the above object, a container delivery method with a foreign chassis in a container terminal according to the present invention is a delivery method for delivering a container between a local chassis traveling in a container yard and a foreign chassis. In a container terminal equipped with an area, the foreign chassis coming to the container terminal is arranged in a standby queue along the delivery area, the position of the side-by-side foreign chassis in the standby queue is detected, and the position is determined as the local chassis. And the container transfer machine that has received the notification moves to a position corresponding to the foreign chassis according to the notification, and the container is transferred between the campus chassis and the foreign chassis. If a foreign chassis that has loaded or unloaded containers exits the waiting queue, it will follow in the waiting queue. Foreign chassis as required by moving sequentially forward is characterized in that to make stuffed wait list that.

  The on-site chassis may be manned or unmanned such as AGV.

  For example, a foreign chassis that unloads a container from a container terminal waits for delivery of the container along the waiting queue when it comes to the building. On the other hand, the designated container is loaded into the storage chassis in the container yard. In this case, the containers loaded on the premises chassis correspond to the order of the foreign chassis in order because of the work efficiency of the premises chassis and the cargo handling machine such as a yard crane that loads containers on the premises chassis. is not. Then, it notifies the on-site chassis and the container transfer machine in which the container has been loaded after the cargo handling operation has been completed to which position in the waiting queue the foreign chassis on which the container is to be re-loaded is located. The container transfer machine is moved to the corresponding position, and the container is transferred from the local chassis to the foreign chassis by the container transfer machine. The foreign chassis loaded with the container exits from the waiting queue, exits, and exits by performing a predetermined procedure at the exit gate. Since a blank portion is formed in the portion where the foreign chassis has been removed, the foreign chassis subsequent to the missing foreign chassis is sequentially advanced and filled as necessary. Note that, for example, when a transfer operation is being performed forward, or when a corresponding on-site chassis has arrived or there is an out-of-the-box chassis that will not arrive until it arrives, it is not appropriate to move, so there is no need to move forward.

  Similarly, foreign chassis that come to carry containers can be transferred to the local chassis along the waiting queue. If the delivery area is divided into a carry-out area for carrying out containers and a carry-in area for carrying in containers, the on-site chassis that has become empty after the transfer of the containers in the carry-out area has been completed. Can receive containers from a foreign chassis in the carry-in area.

  According to a second aspect of the present invention, there is provided a container delivery apparatus for exchanging a foreign chassis in a container terminal with a delivery area for delivering a container between a local chassis traveling in a container yard and the foreign chassis. A standby line area in which foreign chassis coming to the container terminal are arranged along the delivery area is provided, and chassis position detection means for detecting the position of the foreign chassis arranged in the standby line area in the standby line is provided. Providing a chassis position notifying means for notifying the local chassis and the container transfer machine of the position of the foreign chassis detected by the chassis position detecting means, and providing a forward instructing means for permitting the foreign chassis in the standby queue to advance, According to the notification from the chassis position notification means, the on-site chassis and the container transfer machine are not applicable. Move to the position corresponding to the chassis, transfer the container between the local chassis and the foreign chassis, and if the foreign chassis loaded with containers leaves the waiting queue area, if necessary, the forward instruction Means is provided for instructing the foreign chassis to move forward in the waiting queue area.

  The on-site chassis may be manned or unmanned such as AGV.

  For example, a foreign chassis that comes to a container terminal for carrying out a container is arranged in the waiting line area if a predetermined procedure is performed at an entrance gate. On the other hand, the premises chassis and a loading machine such as a yard crane that loads containers stored in the container yard on the premises chassis are moved to the erection position where the instructions are received, and a predetermined container according to the instructions is moved to the premises chassis. To load. The local chassis loaded with the container and the container transfer machine are notified by the chassis position notifying means so as to move to the position in the standby area of the foreign chassis to which the container is to be delivered and moved to the position. To do. Then, the container loaded on the premises chassis is transferred to the corresponding foreign chassis. The foreign chassis loaded with the container exits the waiting area and performs a predetermined procedure at the exit gate. Since a blank portion is formed at the position where the foreign chassis has left, the foreign chassis sequentially moves to a position where the blank portion is filled in accordance with an instruction from the forward instruction means. Note that, for example, when a transfer operation is being performed forward, or when a corresponding on-site chassis has arrived or there is an out-of-the-box chassis that will not arrive until it arrives, it is not appropriate to move, so there is no need to move forward.

  Similarly, foreign chassis that come to carry containers can be transferred to the local chassis along the waiting queue. If the delivery area is divided into a carry-out area for carrying out containers and a carry-in area for carrying in containers, the on-site chassis that has become empty after the transfer of the containers in the carry-out area has been completed. Can receive containers from a foreign chassis in the carry-in area.

  The position of the foreign chassis sent from the chassis position notifying means to the local chassis and the container transfer device is detected by the chassis position detecting means. As this chassis position detecting means, for example, when a visiting foreign chassis performs a predetermined procedure at the entrance gate, an ID tag or the like in which information on containers to be delivered is written is lent to the driver, and the chassis is detected. A method of detecting the position of the foreign chassis by providing an antenna for receiving the signal of the ID tag at an appropriate position of the fence arranged along the transfer area so that the vehicle does not enter by mistake, and container transfer An input means such as a numeric keypad is provided at each position to be a switching point to be performed, and the driver inputs a foreign chassis reception number, chassis number, or other identification number from the input means, whereby the position of the foreign chassis The camera is arranged at the fence or other appropriate position, and the chassis number of the foreign chassis is photographed with the camera. How to recognize the position from the image, it is possible to employ other methods. Further, as the forward instructing means, a traffic light arranged at a position where it can be visually recognized from all the drivers of the external chassis lined up in the waiting line area, a speaker arranged at a position where the driver can hear sounds and contents, or an input Sometimes, a terminal device can be lent to the driver at the entrance gate and the terminal device can be used to instruct the driver of each outpatient chassis.

  According to the container delivery method and the delivery device for the foreign chassis in the container terminal of the present invention, for example, the foreign chassis that came to carry out the containers are arranged in the waiting line area and are sequentially placed in the foreign countries in order from the containers ready for transfer. Since the switching point is moved according to the position of the external chassis so as to be handed over to the chassis, the container can be efficiently transshipped with the minimum number of switching points. In addition, even if the visitor visits the foreign chassis, if the preparation for transshipment of the container to be delivered is completed, the delivery of the container can be quickly received, and the waiting time can be shortened. The same applies to the foreign chassis that came for delivery.

  In addition, a standby place for the foreign chassis may be provided as necessary. Therefore, the entire space of the container terminal can be used more effectively.

  Hereinafter, based on a preferred embodiment shown in the drawings, a container delivery method and a delivery device for a foreign chassis in a container terminal according to the present invention will be specifically described.

  FIG. 2 is a schematic plan view showing an example of a container terminal equipped with a container delivery apparatus suitable for carrying out the container delivery method with the foreign chassis according to the present invention. The container ship 2 is moored to the quay 3 and the container 5 is loaded and unloaded by the quay crane 4. The quay 3 is arranged at the edge of the container yard 6, and the containers 5 loaded and unloaded on the container ship 2 are stored and stored in the storage area 6 a of the container yard 6. An appropriate number of containers 5 are stacked in a matrix to form a container block 5a, and an appropriate number of container blocks 5a are arranged in a matrix in the storage area 6a. For the description of the present embodiment, B to H are given to the rows of the container blocks 5a in order from the land side. In order to move the container 5 in the storage area 6a, a dedicated local chassis 7a is used, and an external chassis 7b is used for land transportation between the container terminal 1 and the shipper. An automatic guided vehicle (AGV) can be used for the local chassis 7a. In addition, it may be a manned transport cart on which the driver gets on. A yard crane 8 is used for loading and unloading the container 5 on the on-site chassis 7a. The yard crane 8 shown in FIG. 2 is a bridge crane, and as shown in FIG. 4, the container 5 is loaded between the container block 5a and the premises chassis 7a stopped to the side of the container block 5a. , Do loading and unloading. The yard crane 8 moves in the traveling direction along the container block 5a and in the perpendicular direction along the right-angle traveling lane 61 between the container block 5a and the container block 5a in order to move to the adjacent container block 5a. Move.

  The foreign chassis 7b enters the container terminal 1 from the entrance gate Gi and exits from the exit gate Go or the sub-gate Gs. This is because the foreign chassis 7b in which the actual container 5 containing the imported cargo is loaded needs to be carried out after the bonded process is performed at the exit gate Go, and the foreign chassis 5 in which the empty container 5 is loaded. 7b or an empty foreign chassis 7b in which the container 5 is not loaded does not need to perform a bonded procedure, and is thus retreated from the sub-gate Gs. On the side of the entrance gate Gi, buildings such as a management building 9, a guardman stuffing station 10, and an office building 11 are arranged. In addition, an empty van pool 12, a repair shop 13, and a water washing place 14 in which empty containers 5 are stored are arranged on the opposite side of the management building 9 across the entrance gate Gi. The installation status of these gates G and the respective facilities around the gates G are not limited to these, and the installation status and required facilities of the gates G differ depending on the container yard operation system. Of course.

  Then, the fence 20 is provided at a position that secures an area where the foreign chassis 7b that has entered from the gate G can move sufficiently and sufficiently so that the foreign chassis 7b cannot enter the storage area 6a of the container yard 6 where the local chassis 7a is traveling. Is installed. The local chassis 7a is used for cargo handling work on the container 5 in the storage area 6a on the sea side, that is, on the inner side of the fence 20, and the foreign chassis 7b is used on the gate G side of the fence 20, that is, on the outer delivery area 6b. 5 is used for loading and unloading. A switching area 21 is provided for transshipment of the container 5 between the local chassis 7a and the foreign chassis 7b with the fence 20 in between. A fence gate 20 a that can be opened and closed is provided at an appropriate position such as an end of the fence 20.

  Further, at both ends of the fence 20, a circular fence 25 is provided that extends toward the storage area 6 a of the container yard 6 and is arranged along the quay 3, and the outer side of the circular fence 25 is connected to the external chassis 7 b. A manned chassis driven by a driver such as a manned premises chassis 7a can run. For this reason, the container 5 can be directly loaded onto the container ship 2 from the foreign chassis 7b, or the container 5 can be loaded directly onto the foreign chassis 7b from the container ship 2 to cope with an emergency or the like. At this time, the quay crane 4 is used for loading and unloading the containers 5.

  The switching area 21 from the left end to the appropriate range in FIG. 2 is a carry-in area 21i so that the foreign chassis 7b can temporarily place the container 5 transported to carry into the container yard 6. . Further, the carry-out area 21o extends from the end of the carry-in area 21i to the right end. The positional relationship between the carry-in area 21i and the carry-out area 21o is determined in accordance with the direction of the container ship 2 berthing to the container terminal 1, and in this embodiment, the on-site chassis 7a is connected to the switching area 21 by being a port berth. 2, the carry-in area 21 i is located on the front side and the carry-out area 21 o is located on the rear side in the traveling direction of the local chassis 7 a. For this reason, the local chassis 7a that unloads the containers 5 in the unloading area 21o can load the containers 5 loaded in the loading area 21i. In addition, the buffer zone part 22 is provided between the carrying-in area 21i and the carrying-out area 21o, and these areas 21i and 21o are divided. The buffer band portion 22 is provided so that the boundary between the carry-in area 21i and the carry-out area 21o can be clarified, and is not necessarily provided if the section between these areas 21i and 21o is clear. In addition, when the number of the containers 5 in the carry-out area 21i and the carry-out area 21o is increased or decreased by providing the buffer band portion 22, both the carry-out container 5 and the carry-in container 5 are provided with the buffer band portion 22. The storage area of the container 5 can be changed easily. When the storage area is changed, the position of the buffer band 22 is also changed.

  A delivery crane 23 as a container transfer machine is arranged in the switching area 21, and the container 5 is loaded into and unloaded from the switching area 21. The delivery crane 23 is preferably the same as the yard crane 8 disposed in the container yard 6. FIG. 4 is a front view of a tire-type bridge-shaped yard crane 8 used for cargo handling work in the container yard 6. The tire-type bridge-shaped yard crane 8 includes two pairs of left and right legs 8b having tires 8a at the lower part, that is, four legs 8b, and a pair of upper and lower legs 8b. No. 8c is spanned in parallel. Guided by the pair of girders 8c, the trolley 8d is movable in the transverse direction, which is the left-right direction in FIG. 4, and the block 5a of the stacked container 5 and the on-site chassis 7a stopped on one side of the block 5a. , The container 5 is loaded onto or unloaded from the chassis 7 by being suspended by the trolley 8d. The container 5 is held and lifted by a spreader 8e that is moved up and down by a trolley 8d. In addition, the cab 8f on which the operator is boarded moves together with the trolley 8d, and the operator operates the trolley 8d. When the yard crane 8 is operated unattended, the operator is not on board, but is operated automatically or by a remote device.

  As described above, the yard crane 8 moves in the direction along the container block 5a in a state of straddling the container block 5a, that is, in the traveling direction that is the direction penetrating the paper surface in FIG. 4, and from one container block 5a. In order to move to another adjacent container block 5a, it is possible to move in a direction along the right-angled traveling lane 61, that is, a right-and-left direction in FIG. For this reason, the rotation axis of the tire 8a is rotatable about an axis in the vertical direction, and the direction of movement can be changed by changing the direction of the rotation axis.

  FIG. 1 shows the container yard 6 shown in FIG. 2, and shows the traveling path of the local chassis 7a traveling in the storage area 6a. The on-site chassis 7a has the container 5 between the container ship 2 and the storage area 6a (the travel trajectory between them is referred to as a “quake route”), and between the storage area 6a and the switching area 21 (the travel trajectory therebetween). Is referred to as a “route around the delivery area”). In order to load and unload the containers 5 in the storage area 6a, the storage lanes 31 arranged between the B to H rows of the respective container blocks 5a are traveled to the storage position. For this reason, the storage lane 31 is common to the quay route and the delivery area route. The quay route is composed of a plurality of loading lanes 26 arranged along the quay 3 and B to H rows of container blocks 5a, an approach lane 27 along the sea-land direction passing through the left side in FIG. The exit lane 28 extends along the sea-land direction, and enters the storage lane 31 from the entry lane 27 and exits from the storage lane 31 to the exit lane 28. Further, the route around the delivery area is the approach lane 33 along the sea-land direction passing through the left side in FIG. 1 in the B to H rows of the plurality of delivery lanes 32 and the container blocks 5a arranged along the switching area 21. And the exit lane 34 along the sea-land direction that passes through the right side, enters the storage lane 31 from the entry lane 33, and exits from the storage lane 31 to the exit lane 34. That is, the storage lane 31 is connected to each of the entry lanes 27 and 33 and each of the exit lanes 28 and 34. The loading lane 26 and the delivery lane 32 may be provided one by one. However, if a plurality of the lanes 26 and the delivery lanes 32 are provided, a part of the plurality of lanes 26, 32 is a part of the lanes 26. , 34 can be used as a lane for overtaking the local chassis 7a during the cargo handling operation.

  As described above, in this embodiment, since the container ship 2 is on the port side, the premises chassis 7a travels along the cargo lane 26 from the right side to the left side in FIG. In the delivery lane 32, the local chassis 7a travels in one-way from the right side to the left side in FIG. For this reason, on the quay route, the premises chassis 7 a can return from the loading lane 26 to the loading lane 26 through the approach lane 27, the storage lane 31, and the exit lane 28. In the route around the transfer area, the local chassis 7 a can return from the transfer lane 32 to the transfer lane 32 through the approach lane 33, the storage lane 31, and the exit lane 34. Further, the local chassis 7 a that has traveled in the storage lane 31 can proceed to either the exit lane 28 or the exit lane 34. Therefore, for example, the local chassis 7a that has entered the storage lane 31 from the route around the quay can proceed to the route around the delivery area. The approach lanes 27 and 33 and the exit lanes 28 and 33 along the sea-land direction are all arranged with the lanes 27 and 28 of the route around the quay close to the container block 5a.

  The container 5 includes a so-called refrigerated container that can maintain the stored cargo in a refrigerated state, for example. This refrigerated container needs to protect the refrigeration device from seawater. It is loaded on a container ship with its body on the bow side. For this reason, the direction in which the door is facing is opposite to that of the other containers, and when the container yard 6 is transported in the same manner as the other containers 5, the direction of the doors in the container yard 6 is reversed. turn into. Therefore, it is necessary to face the door body in the same direction as the other containers 5 in the container yard 6, and for this purpose, a switchback area 37 for exchanging the front and rear of the local chassis 7a is provided.

  Further, as shown by broken lines in FIG. 1, the entry lane 27 is between the B row and the C row, the D row and the E row, and the F row and the G row of the container block 5a. A reverse running lane 36 connected to all of the approach lane 33, the exit lane 28, and the exit lane 34 is disposed substantially parallel to the storage lane 31. That is, the local chassis 7a traveling in the exit lane 28 or the exit lane 34 passes through the reverse travel lane 36 to reach either the entrance lane 27 or the entrance lane 33, and enters the storage lane 31 from these entrance lanes 27, 33. You can move forward.

  As shown in FIG. 1, in the switching area 21, a waiting line area 21a in which the foreign chassis 7b can be arranged and arranged is provided on the delivery area 6b side to receive the container 5. The foreign chassis 7b installed in the container terminal 1 is arranged in the waiting line area 21a. At a position where the driver of the external chassis 7b lined up in the waiting line area 21a can visually recognize, a traffic signal as forward instruction means (not shown) is provided.

  Further, chassis position detection means (not shown) is provided so that the position of each of the external chassis 7b arranged in the waiting line area 21a is detected. For example, an antenna that lends an ID tag or a terminal device at the entrance gate Gi when the foreign chassis 7b is installed, and can exchange a signal from the ID tag or an information signal with the terminal device at the fence 20 or other appropriate position. The position of the corresponding foreign chassis 7b can be detected based on these signals. Then, the detected position information of the foreign chassis 7 b is sent to a management device including a main computer that manages the container terminal 1, and provided to the local chassis 7 b and the delivery crane 23 from the management device.

  As the delivery crane 23, a bridge-type crane is used as shown in FIG. 3, and the same one as the yard crane 8 described above is preferable. The transfer crane 23 transfers the container 5 between the local chassis 7a and the foreign chassis 7b.

  The container delivery device method with the foreign chassis in the container terminal of the present invention configured as described above and the operation of the delivery device will be described below.

  The foreign chassis 7b that has come to receive the container 5 that has actually entered the container terminal 1 performs a predetermined procedure at the entrance gate Gi. At this time, for example, the ID tag specifying the foreign chassis 7b is lent. When the procedure is completed, the process proceeds to the waiting queue area 21a and is arranged at an appropriate position in the waiting queue. At this time, the foreign chassis 7b is the last part of the foreign chassis 7b already arranged in the standby queue area 21a, or a blank portion formed by the exit of the foreign chassis 7b from the standby queue after completion of the cargo handling operation, as will be described later. Can line up. If they are lined up in the waiting queue area 21a, the signal of the ID tag is captured by an antenna (not shown) provided on the fence 20 and sent to a management device such as a management center, and the foreign chassis 7b is lined up in the waiting queue. That is confirmed.

On the other hand, in the storage area 6a, the container 5 is loaded on the premises chassis 7a by the yard crane 8. The loading work of the container 5 is based on the work efficiency based on the relationship between the yard crane 8 and the campus chassis 7a and the storage position of the container 5 to be loaded on the campus chassis 7a, and the arrival of the foreign chassis 7b that has received the container 5. This is done in response to an instruction from the management center in consideration of the composition. Therefore, it does not necessarily coincide with the order of the foreign chassis 7b. When the loading operation of the corresponding container 5 is completed, a message to that effect is sent to the management device. As a result, the management device notifies the local chassis 7a of the position in the standby queue area 21a of the foreign chassis 7b that has come to receive the container 5 loaded in the local chassis 7a.
Similarly, the management device delivers the position of the foreign chassis 7 b and notifies the crane 23. Thereby, the local chassis 7a and the delivery crane 23 move to the notified position to form a switching point, and transfer the container 5 to the foreign chassis 7b. Then, the foreign chassis 7b loaded with the container 5 exits from the waiting line area 21a and heads toward the exit gate Go, performs a predetermined procedure, and retreats to transport the cargo in the container 5 to the shipper.

  When the foreign chassis 7b exits, the portion becomes a blank portion, and the advance instruction means prompts the driver of the foreign chassis 7b following the blank portion to move forward and close the waiting queue. As a result, the driver advances the foreign chassis 7b so as to sequentially fill the blank portion. For example, when the forward instructing means is a traffic light, the traffic light is disposed at a position where it can be seen by the drivers of all the external chassis 7b in the waiting queue area 21a, and movement is permitted and stopped by its color display. To be instructed. When the waiting external chassis 7b moves in the waiting queue area 21a, the signal transmission position from the ID tag changes, and this change is captured by the management device and the changed position is recognized. . Then, the corresponding local chassis 7a moves to the new position, and the container 5 is transferred. In other words, the foreign chassis 7b arranged in the standby queue area 21a and having the container 5 transferred leaves the standby queue area 21a, and the container 5 is moved by the subsequent foreign chassis 7b being packed in the empty space after the withdrawal. I will wait to be posted.

  On the other hand, the foreign chassis 7b that comes to carry the actual container 5 containing the export cargo goes to the carry-in area 21i, and the container 5 is transferred to the local chassis 7a by the delivery crane 23 in the carry-in area 21i, Alternatively, the container 5 is temporarily placed in the carry-in area 21i. When there is a temporarily placed container 5 in the carry-in area 21i, or when there is a foreign chassis 7b that has been visited to carry the container 5, the container 5 is handed over to the foreign chassis 7b in the carry-out area 21o and is unloaded. The premises chassis 7a that has become receives the container 5 in the carry-in area 21i and transports it to the storage area 6a.

  In this embodiment described above, since a plurality of delivery lanes 32 are provided along the switching area 21, the transfer operation can be performed by a plurality of delivery cranes 23, and the switching points are performed at a plurality of locations. be able to. If a lane for change is provided so that the lanes can be changed between the plurality of transfer lanes 32, for example, the transfer lane 32 on the storage area 6a side is set as the overtaking lane, and the transfer lane 32 is set on the transfer area 6b side. By using the delivery lane 32 as a work lane for cargo handling, even when there is a yard chassis 7a in front of the cargo handling work, it may be overtaken to move to a further working position or return to the storage area 6a. it can.

  The arrangement structure of various facilities such as the arrangement of container blocks and storage lanes in the container terminal described above is an example, and there are various arrangements depending on the container terminal. The facility arrangement structure according to the present invention is implemented in accordance with the arrangement of the storage lanes, the arrangement of the storage lanes, and the like.

  According to the container delivery method and delivery device for the foreign chassis in the container terminal according to the present invention, the local chassis can transport the container and deliver the container to the foreign chassis regardless of the order of the foreign chassis. For this reason, the work efficiency of the on-site chassis in the container yard is improved, and the time required to deliver the container to the foreign chassis can be shortened. In addition, since it takes no time to call the foreign chassis corresponding to the container ready for delivery from the standby place, the standby time of the foreign chassis can be shortened. In addition, since it is not necessary to provide a standby place for the foreign chassis, the site of the container terminal can be used more effectively as a storage space for the container, and the existing container terminal can be easily modified and used. Furthermore, since it is suitable for a structure provided with a switching area, it contributes to promoting the introduction of an unmanned operation system in which a local chassis is an unmanned transport cart.

FIG. 2 is a schematic plan view of a container yard suitable for carrying out a container delivery method and a delivery device with a foreign chassis according to the present invention, and shows a part of FIG. 2 in an enlarged manner. It is a schematic top view which shows an example of the container terminal provided with the container delivery method and the delivery apparatus with the foreign chassis which concern on this invention.
