Description

  The present invention relates to a container terminal including a forward path and a return path extending in a longitudinal direction of a storage lane for storing containers, and a transport carriage that self-travels in the reverse direction when traveling on the forward path, and a control method thereof.

  The container terminal is a facility for loading or unloading containers to / from a ship, and loading and unloading containers with an external chassis for land transportation. It is also a facility that temporarily stores containers that have been loaded or unloaded.

  At present, with the rapid development of container transportation systems on international routes, automation and labor saving of cargo handling and storage operations in container terminals are desired. In other words, it is important to transport containers between the ship and the container terminal, to automate and improve the efficiency at the container storage part of the container terminal, and to reduce the cost.

  Therefore, there is a cart (transport cart) that holds and transports both ends of one container in pairs (see, for example, Patent Document 1). In this cart, the cart for carrying the container is made smaller than the conventional cart, improving the efficiency of carrying the container and reducing the power consumption.

  On the other hand, there is also a container terminal that is adjacent to a storage lane for storing containers, and has a forward path and a return path extending in the longitudinal direction of the storage lane, and self-travels in the reverse direction when the cart travels in the forward path (for example, , See Patent Document 2). This container terminal divides the traveling path of the cart adjacent to the storage lane into an outbound path where the cart travels with the container mounted thereon and a return path where the cart travels without mounting the container, thereby allowing the cart to carry containers one after another. The cargo handling efficiency is improved.

  Here, the operation of the container terminal combining these two devices will be described with reference to FIG. In the container terminal 1 </ b> X, when the container C is unloaded from the ship S, the container C loaded by the quay crane GC is first transported to the sea-side delivery area 3 by the circular transport carriage 7.

  Next, the delivery platform 5 in the seaside delivery area 3 mounts the container C on two carts 9, and the two carts 9 self-propelled in the forward path 11, and the container C is moved to one of the yard cranes. Carry to 6. Next, the yard crane 6 receives the container C from the two carts 9 and stores it in the storage lane 2. Then, the two carts 9 are transferred from the forward path 11 to the return path 12, and each travels independently on the return path 12 to return to the original.

  When loading into the ship S, the reverse operation is performed, and the cart 9 self-travels on the return path 12, is transferred from the return path 12 to the outbound path 11, travels on the outbound path 11, and receives the container C from the yard crane 6.

  When carrying a container from the outside, first, the foreign chassis 8 carries the container C to the land-side delivery area 4. Next, the delivery platform 5 in the land-side delivery area 4 mounts the container C on the two carts 9, and the two carts 9 transport the container C to one of the yard cranes 6. Next, the yard crane 6 receives the container C from the two carts 9 and stores it in the storage lane 2. When carrying out to the outside, the reverse operation is performed.

  In each operation, the cart 9 carries one container C as a set of two cars and travels on the forward path 11, moves to the return path 12, returns to the original state, or travels on the return path 12, and travels to the outbound path 11. Move, return to original with container C loaded. At this time, the cart 9 is lifted or lifted for the movement between the forward path 11 and the return path 12, or the cart 9 is lifted in the vertical direction instead of the transfer machine 13X. This is done using a conveyor (not shown) that moves to and from the return path 12.

  However, in the method using the transfer machine 13X or the method using the conveyor, it is necessary to lift or lift the cart 9 having its own weight of about 2 tons, and in that state, it moves between the forward path 11 and the return path 12. Therefore, it took time to move the cart 9.

  Further, when the cart 9 moves between the forward path 11 and the return path 12, the cart 9 is lifted or lifted from the rail, whereby the wheels of the cart 9 and the rail of the forward path 11 or the return path 12 are separated from each other. Therefore, it is necessary to accurately align the wheels and the rails of the forward path 11 and the return path 12. At this time, when the cart 9 is lowered onto the rail, the dimensional difference between the rails of the forward path 11 and the return path 12 and the wheels of the cart 9 must be within about 5 mm, and high-precision operation or control is possible. is necessary.

  Further, if both ends of the forward path 11 and the return path 12 are formed in an annular shape without using the transfer machine 13X, the cart 9 can move between the forward path 11 and the return path 12 by self-propelling. It is necessary to increase the width between the forward path 11 and the return path 12 by making an annular shape, and the interval between the storage lanes 2 is widened, and a new problem that a large number of storage lanes 2 cannot be arranged Occur.

  The present invention has been made in view of the above-described problems, and the object of the present invention is to perform the movement between the forward path and the return path adjacent to the storage lane by the self-propelling of the transport carriage, thereby Containers that can be moved quickly and easily without the need for advanced operations, and that can improve the cargo handling efficiency by allowing the transport cart carrying the containers to be self-propelled in an annular shape. It is to provide a terminal and its control method.

  A container terminal according to the present invention for solving the above-described object is provided with an outward path and a return path extending in the longitudinal direction of the storage lane adjacent to the storage lane storing the container, and the forward path mounted with the container. In a container terminal that is self-propelled and includes a transport carriage that self-propels the return path in the direction opposite to the direction of self-propelled travel without mounting the container, the transport cart extends the forward path and the return path. A self-propelled device capable of self-propelling in a direction substantially orthogonal to the extending direction without changing the direction and direction of the transport cart, and intersecting each of the forward path and the return path, and the transport cart is the transport It is configured with a connection path that runs on its own without changing the direction of the carriage.

  According to this configuration, the transport cart can smoothly travel between the forward path and the return path by changing the direction of the transport cart and changing only the self-running direction. Accordingly, the transport cart is not lifted or transferred while being lifted, and the travel between the forward path and the return path can be quickly performed by the self-propelling of the transport cart.

  Further, in the container terminal, the forward path, the return path, or the connection path is formed by a pair of rails that are interrupted at a portion that intersects the other, and the one of the interrupted portions is formed by the transport cart. When self-propelled, it is provided with a flange rail that self-propelled by rolling the flange portion of the wheel of the carriage, and the other is formed by a pair of rails that are interrupted at a portion intersecting with the flange rail. In addition to the effects of the above, it is possible to smoothly run the transport cart at the intersecting portion.

  When the entire length of the vehicle is long and a single vehicle has many wheels like a railway vehicle, even if the crossing portion of the traveling rail is formed by so-called diamond crossing, the vehicle can travel without problems. If the entire length is short and the wheels provided on one transport cart cross all of the intersections, there is a possibility that wheel removal will occur.

  According to the above configuration, the interval between the rails on one of the forward path, the return path, and the connection path is narrowed so that the transport cart smoothly runs even if the rail is interrupted, and the other rail is transported on the transport cart. When the vehicle is self-propelled, it can smoothly straddle one rail using the wheel flange. Thereby, when the transport cart is self-propelled in a portion where the forward path or the return path intersects the connection path, it is possible to prevent the wheel from being removed.

  In addition, in the container terminal, a first wheel stop for aligning a wheel of the transport carriage and the connection path is provided on the end side of the forward path and the return path, and the transport is provided on both ends of the connection path. With the second wheel stopper for aligning the position of the wheel of the carriage with the position of the forward path or the return path, before the transport carriage self-travels the connection path, and before the transport cart self-travels the forward path or the return path, Wheel alignment can be performed. Thereby, since alignment with the rail and the wheel of a conveyance trolley which generate | occur | produces when forming the travel path of a conveyance trolley with a rail can be performed easily, advanced operation can be omitted.

  Furthermore, in the container terminal described above, when the connection path is provided at each of both ends of the forward path and the return path, and the travel path on which the transport carriage is self-propelled is formed by at least one annular path, the transport cart is forward path And a self-propelled road including a return path, and a transport cart can transport containers one after another. Thereby, a container can be conveyed efficiently and cargo handling efficiency can be improved. In addition, since the distance between the forward path and the return path can be narrowed compared to an annular path provided with an annular traveling path at the end of the forward path and the return path, the storage can be arranged in the container terminal. The number of lanes can be increased.

  In addition, in the container terminal, the storage lane includes a loading container area for storing containers to be loaded from outside, and a loading container area for storing containers to be loaded to the outside, and the loading container area; The connection path is provided in the vicinity of the extended line of the boundary with the carry-out container area, and when carrying in the carry-in container area, the carry-in annular path in which the transport cart self-propels, and when carrying out in the carry-out container area, If a carry-out circular path on which the transport cart is self-propelled is formed, the travel distance of the transport cart can be shortened. Thereby, while shortening the time for which a conveyance trolley travels annularly, the number of conveyance trolleys can be decreased.

  For example, when unloading a container from the container terminal to the outside, since the cargo handling work is performed only in the unloading container area, it is useless for the transport cart to travel to the loading container area. It is possible to save the travel of a heavy transport cart.

Further, in the container terminal, the self-propelled device is configured such that the main wheel that rolls on the forward path and the return path, the connection path wheel that rolls on the connection path, and the main wheel or the connection path wheel. A wheel lifting device that holds the other in a position not in contact with the forward path, the return path, and the connection path when one of them is rolling, Since it can hold | maintain in the position which does not contact an outward path, a return path, and a connection path, the movement between an outward path and a return path can be performed smoothly.

  In addition, since at least one of the main wheel or the connection road wheel is in contact with the rail, the alignment between the rail and the wheel is compared with the method of lifting the transport carriage including the wheel, or lifting and transferring, It can be done easily.

  On the other hand, in the container terminal, the self-propelled device rolls the forward path, the return path, and the connection path, and the common wheel rolls in the rolling direction of the shared wheel, the forward path, the return path, or the connection path. When the wheel rotation device rotates in either one of the transport cart or the portion where the forward path and the return path intersect the connection path. If a lifting device that holds the wheels in a position that does not contact the forward path, the return path, and the connection path is provided, the self-running direction of the transport cart can be changed simply by rotating the shared wheel.

  In addition, in the container terminal, when the transport cart that is connected to one of the outbound route or the inbound route and cannot travel by itself is provided with a failed vehicle path that is pushed into the follower cart, the outbound route or the inbound route The transport cart that has become unable to run on its own can be pushed to the road of the broken vehicle with the transport cart that has been traveling behind the transport cart. Thereby, even if a transport cart breaks down, it can continue without stopping the cargo handling operation of the container terminal.

  In addition, the container terminal control method for solving the above-mentioned object is provided with the container including the forward path and the return path extending in the longitudinal direction of the storage lane adjacent to the storage lane in which the container is stored, and the forward path. In a container terminal control method comprising a carriage that self-propels and travels in a reverse direction to the direction of self-propelled traveling in the forward path without mounting the container, the container terminal is provided with each of the outbound path and the inbound path. A crossing connection path; a first wheel stop provided on an end side of the forward path and the return path; and a second wheel stop provided on both ends of the connection path, the forward path to the return path or the return path When moving from the forward path to the forward path, the position of the wheel of the transport carriage and the connection path is aligned with the first wheel stop, and the transport carriage automatically moves the connection path without changing the direction of the transport carriage. First to run After the step and the second step, the second wheel stop is used to align the wheel of the carriage with the forward path or the return path with the second wheel stopper, so that the transport carriage does not change the direction of the transport carriage. Or a second step of self-propelled on the return path.

  According to this method, the carriage is moved in the direction substantially orthogonal to the extending direction of the forward path and the return path, and the carriage is moved in the direction of the carriage with the exact position of the wheel and the traveling path of the carriage. This can be done by self-propelling the connection path.

  According to the present invention, the movement between the forward path and the return path adjacent to the storage lane is carried out by the self-propelled carriage so that the movement between the forward path and the return path can be quickly and highly sophisticated. It is possible to easily carry out the operation, and it is possible to make the transport cart carrying the container self-propelled in a ring shape, thereby improving the cargo handling efficiency. Thereby, since a container can be efficiently conveyed to a conveyance trolley, cargo handling efficiency can be improved and power consumption can be reduced.

  Hereinafter, a container terminal according to an embodiment of the present invention will be described with reference to the drawings. In this embodiment, a container terminal in which the storage lane has a longitudinal direction in the sea-land direction will be described as an example. However, the present invention is not limited to this, and for example, the storage lane has a longitudinal direction in a direction orthogonal to the sea-land direction. It can be applied to container terminals. Note that the dimensions of the drawings are changed so that the configuration can be easily understood, and the ratios of the thicknesses, widths, lengths, and the like of the respective members and parts do not necessarily match the ratios of actually manufactured parts.

  First, a container terminal according to a first embodiment of the present invention will be described with reference to FIGS. In place of the conventional container terminal transfer machine shown in FIG. 11, the container terminal 1 is adjacent to the storage lane 2 as shown in FIG. 1, and an outward path 11 and a return path 12 along which a cart (transport cart) 9 is self-propelled. At both end portions, there are moving parts 13a and 13b, and an annular path 10 indicated by an arrow in the figure is formed from the forward path 11, the return path 12, and the moving parts 13a and 13b.

  The circular road 10 is, for example, that the cart 9 travels on the forward path 11 and moves to the return path 12 from the forward path 11 by the moving unit 13b. It is a traveling road that self-propels and moves from the return path 12 to the forward path 11 by the moving unit 13a, and is a bidirectional (clockwise or counterclockwise) annular path adjacent to the storage lane 2.

As shown in FIG. 2, the cart 9 is an unmanned transport cart, and can be self-propelled in the direction from the sea 11 to the land and from the sea to the sea, that is, from the land to the sea, that is, in both directions. It is a simple transport cart. As the cart 9, for example, one that can mount one container C can be used, but it is preferable that the cart 9 can be transported by holding both ends of the container C by two. In this embodiment, a mechanism for driving the wheels is assumed to use a known technique, and the description thereof is omitted.

  As shown in FIG. 2A, the cart 9 includes a main traveling device 20 having a main wheel 21 that rolls on the forward path 11 or the return path 12, and a connection path wheel 31 that rolls on the connection path 13. A travel device 30 for connecting roads. Although a plurality of wheels are mounted on the cart 9, since they overlap, only one of them is attached in the drawing.

  The main wheel 21 is composed of a wheel part 21a that rolls on the rail of the forward path 11 or the return path 12, and a flange part 21b that is provided on the edge of the wheel part 21a to prevent derailment. Similarly, the wheel 31 includes a wheel portion 31a and a flange portion 32b. In addition, the connection path travel device 30 includes an elevating device 32 that elevates and lowers the connection path wheels 31 in the vertical direction.

  The main traveling device 20 rotates the main wheel 21 to cause the cart 9 to self-travel in both directions (a or b in the drawing) in the extending direction of the forward path 11 or the return path 12. This is a device for rotating the connection path wheel 31 to make the cart 9 self-propelled in both directions (c or d in the figure) in the extending direction of the connection path 14.

  As shown in FIG. 2 (b), the lifting device 32 only needs to be able to vertically lift and lower the connection wheel 31 and the mechanism for driving the same, and uses a lifting device of a known technique. be able to. For example, a damper driven by hydraulic pressure.

  As shown in FIG. 1, the forward path 11 and the return path 12 are formed by a pair of rails extending in the longitudinal direction of the storage lane 2, that is, the sea-land direction, the forward path 11 is disposed on the storage lane 2 side, and The return path 12 is arranged substantially in parallel. The forward path 11 is a traveling path in which two carts 9 are paired and transports the container C, and the return path 12 is a traveling path in which the cart 9 does not transport the container C and travels one by one.

  As shown in FIG. 3, the moving unit 13 (the moving units 13 a and 13 b have the same configuration and are unified in the following 13) includes a connection path 14 that intersects each of the forward path 11 and the return path 12. The connection path 14 is formed by a pair of rails that are interrupted at a portion that intersects the forward path 11 or the return path 12, and a flange rail 15 is provided at the interrupted part (hereinafter referred to as a disconnection part 14 a).

  In addition, the first wheel stopper 16 a is provided on the end side of the forward path 11 and the return path 12, and the second wheel stopper 16 b is provided on both ends of the connection path 14. In addition, the vehicle includes a broken vehicle path 17, a control device 18, and a cart sensor (transport cart sensor) 19.

  The connection path 14 is arranged so as to intersect with each of the forward path 11 and the return path 12 so as to be substantially perpendicular. The connection path 14 is a travel path in which the cart 9 rolls the connection path wheels 31 while keeping the direction of the cart 9 as it is and moves from the forward path 11 to the return path 12 or from the return path 12 to the forward path 11.

  As shown to (a) of FIG. 4, the outward path 11 is formed with a pair of rail provided with the part (henceforth the interruption part 11a) interrupted in the part which cross | intersects the rail 15 for flanges of the connection path 14. As shown in FIG.

The gap L1 between the discontinuous portions 11a is such a narrow width that the main wheel 21 of the cart 9 does not take off when the discontinuous portion 11a passes, the main wheel 21 does not fit, or the impact due to the gap does not increase. Yes, preferably narrower than the width L2 of the connecting road wheel 31 in the width direction and wider than the width L3 of the flange portion 31b of the connecting road wheel 31 in the width direction. Thereby, when the cart 9 self-propels the outbound path | route 11 which carries two containers 9 and carries the container C, the vertical change in the interruption part 11a can be suppressed.

  As shown in FIG. 4B, the connection path 14 includes a discontinuity portion 14 a at a portion intersecting with the forward path 11, and a flange rail 15 is disposed in the discontinuity portion 14 a, and the connection path is connected by the flange rail 15. Compensates for 14 broken parts.

  When the distance L4 of the interrupted portion 14a is made as long as possible so that the main wheel 21 rolls on the forward path 11 and is shortened as much as possible, the cart 9 travels on the flange portion 31b of the connection path wheel 31. Can be kept straight. Moreover, since the overlapping part of the connection path 14 and the rail 15 for flanges also becomes long, it can hold | maintain linearity more. In addition, a guide may be provided on the flange rail 15 to maintain straightness when the cart 9 travels on the flange portion 31b of the connection path wheel 31.

  The flange rail 15 is formed by a rail having a width direction in the extending direction of the outward path 11 and a longitudinal direction in the extending direction of the connecting path 14, and the flange 31b of the outbound path 11 connecting path wheel 31 rolls. To do. The flange rail 15 is sandwiched by the outward path 11 at the interrupted portion 11a. Preferably, when the flange rail 15 and the outward path 11 are brought into contact with each other, the cart 9 travels on the flange portion 31b of the connection path wheel 31. Since the forward path 11 protruding from the flange rail 15 serves as a guide, it is possible to maintain straightness.

  In addition, the flange rail 15 has a slope on which the flange 31b of the connection path wheel 31 can roll so that the cart 9 can travel smoothly on the connection path 14 and straddle the outbound path 11. However, when the rail of the forward path 11 is straddled, the height at which the wheel 31a of the connecting path wheel does not contact the rail of the forward path 11 is preferable.

  When the first wheel stopper 16a is moved to the end of the forward path 11 or the return path 12, more specifically, when the position where the first wheel stopper 16a and the main wheel 21 are in contact with each other and the cart 9 is stopped, the connection path wheel 31 is lowered. The flange 31b of the connection path wheel 31 and the flange rail 15 are arranged so as to be in a precise contact position.

  The first wheel stopper 16a is preferably movable so that it does not interfere with traveling when the cart 9 that has become unable to run on its own is retracted to the broken vehicle path 17.

  The second wheel stopper 16b is located at both ends of the connection path 14, more specifically, the position at which the cart 9 that has been traveling on the connection path 14 in contact with the second wheel stopper 16b and the connection path wheel 31 is stopped is the main position. It arrange | positions so that it may become a position which the wheel part 21a of the main wheel 21 and the rail of the outward path 11 or the return path 12 contact correctly, when the wheel 21 is dropped.

  According to said structure, while making the space | interval which the rail of the outward path 11 interrupted narrow, and the cart 9 self-propels the rail of the connection path 14, it uses the flange part 31b of the wheel 31 for connection paths, and is going out. Since 11 rails can be straddled smoothly, it is possible to prevent wheel removal and the like. Moreover, since the space | interval L1 of the interruption part 11a of the outward path 11 can be narrowed, when the cart 9 passes the interruption part 11a, it can pass without being influenced by the interruption part 11a.

  Further, the first wheel stopper 16a and the second wheel stopper 16b are used to align the wheel portion 21a of the main wheel 21 with the outward path 11 or the return path 12, or the flange portion 31b of the connection path wheel 31 and the flange rail 15 Can be accurately and easily performed.

  In this embodiment, the flange rail 15 that is sandwiched between the forward path 11 by the interrupted portion 11a and connects the connection path 14 by the interrupted portion 14a is provided. May be provided with a rail for flange that can be rolled. However, when the cart 9 travels on the forward path 11, since the cart 9 has the container C mounted in a set of two, the transport of the container C may be affected.

  Next, the operation of lowering the connection path wheel 31 to the flange rail 15 by the lifting device 32 and lifting and holding the main wheel 21 to a position where it does not contact the forward path 11 and the connection path 13 will be described. As shown in FIG. 5A, when the cart 9 is traveling on the forward path 11, the lifting device 32 holds the connection path wheel 31 at a position where it does not contact the forward path 11.

  When the main wheel 21 and the first wheel stopper 16a come into contact with each other and the cart 9 stops, the lifting device 32 lowers the connection path wheel 31 downward in the vertical direction as shown in FIG. The flange portion 31 b of the connection path wheel 31 is in contact with the flange rail 15.

  Next, as shown in FIG. 5C, the lifting device 32 lifts the main wheel 21 to a position where it does not come into contact with the forward path 11. Thereby, the direction of the cart 9 can be left as it is, and only the self-running direction can be changed.

  According to this operation, when one of the main wheel 21 and the connection path wheel 31 is rolling, the other wheel is brought into a position where it does not come into contact with the forward path 11, the return path 12, and the connection path 14. Since it can hold | maintain, the movement between the return paths 12 can be performed.

  Moreover, when changing the self-running direction of the cart 9, since at least one of the main wheel 21 or the connection path wheel 31 is in contact with the rail, the first wheel stopper 16a and the second wheel stopper 16b are used. Compared with the method of lifting or lifting the transport carriage including the wheels and transferring the rails and the wheels, it becomes easier and the advanced operation can be omitted.

  The broken vehicle path 17 is arranged on an extension of the forward path 11. It is preferable to provide at least one broken vehicle path 17 on each of the outbound path 11 and the inbound path 12. Further, the broken vehicle path 17 is formed by the same rails as the forward path 11 and the return path 12.

  The control device 18 is a microcontroller that comprehensively performs electrical control that is in charge of controlling the container terminal 1 by an electric circuit, and the main travel of the cart 9 based on signals detected by the cart sensors 19a and 19b. The drive of the apparatus 20, the connection path | route traveling apparatus 30, and its raising / lowering apparatus 32 is controlled. For example, the control device 18 may be provided in a management building that manages cargo handling work.

  The cart sensor 19a only needs to be able to detect the cart 9 at a portion where the forward path 11 or the return path 12 intersects the connection path 14, and the cart sensor 19b detects the cart 9 on the failed car path 17. It is only necessary to be able to do this, and a sensor of a known technique can be used. For example, a sensor that detects the cart 9 by an image or a sensor that detects the cart 9 in conjunction with a transmitter provided on the cart 9 side may be used.

  Next, a method for controlling the container terminal 1 when the cart 9 moves between the forward path 11 and the return path 12 will be described with reference to FIGS. 5 and 6. In this example, the cart 9 is self-propelled on the outward path 11 from the sea side or the land side, and the return path 12 is self-propelled from the land side to the sea side. Since the movement when running is the same operation, it is omitted. Further, in the figure, the self-running direction at the main wheel 21 of the cart 9 is indicated by arrows a and b, and the free-running direction at the connection path wheel 31 is indicated by arrows c and d.

  First, as shown in FIG. 6 (a), when the cart 9 that has been traveling in the traveling direction a from the sea side to the land side in the traveling direction a comes into contact with the first wheel stopper 16a (step S1), The sensor 19a detects the cart 9 (step S2). Next, the control device 18 stops the cart 9 (step S3). At this time, a step for determining whether or not the stop position of the cart 9 is correct may be performed.

  Next, as shown in FIGS. 5A to 5C, the control device 18 changes the self-running direction of the cart 9 (step S4). Next, as shown in FIG. 6B, the control device 18 drives the connecting road travel device 30 to rotate the connecting road wheel 31, and connects the cart 9 in the self-running direction c. Make 14 self-run. (Step S5).

  Next, when the cart 9 comes into contact with the second wheel stopper 16b (step S6), the cart sensor 19a detects the cart 9 (step S7). Next, the control device 18 stops the cart 9 (step S8). Next, as shown in FIG. 6 (c), the control device 18 lowers the main wheel 21 to the return path 12 by the elevating device 32 in the same manner as described above, and the connection path wheel 31 is connected to the return path 12 and the connection path 14. Lift to a position where it does not touch and hold it (step S9).

  Next, the control device 18 drives the main traveling device 20, rotates the main wheel 21, and causes the cart 9 to self-travel in the self-traveling direction b (step S10), and this control method is completed. To do.

  According to this control method, without changing the direction of the cart 9, the traveling direction of the cart 9 is switched from the main wheel 21 to the connection road wheel 31 or from the connection road wheel 31 to the main wheel 21. 11 and the return path 12 can be moved by the self-propelling of the cart 9, so that the cart 9 can be moved substantially at a right angle between the forward path 11 and the return path 12 arranged substantially in parallel.

  Further, since the cart 9 is moved by the cart 9 by itself, the movement between the forward path 11 and the return path 12 is faster than the method of lifting or lifting the cart 9 together with the wheels, and the first wheel stopper 16a and the second wheel stop 16a. By using the wheel stopper 16b, it is possible to easily align the wheels of the cart 9 and the rails of the outward path 11 or the return path 12. In addition, it is not necessary to provide a separate transfer device or the like, and further, since the cart 9 is not moved while being lifted, power consumption can be reduced.

  If the cart 9 enters the moving unit 13 and is configured to supply power to the cart 9, power can be supplied to the cart 9 at both ends of the forward path 11 and the return path 12. As this power feeding method, for example, contact-type power feeding such as non-contact power feeding or panda graph can be used.

  Next, the operation of the container terminal 1 of the first embodiment in which the above operation is performed at both ends of the forward path 11 and the return path 12 will be described with reference to FIG. As shown in FIG. 1, the container terminal 1 is configured such that the traveling path of the cart 9 is an annular path 10 composed of an outward path 11, a return path 12, and moving parts 13 a and 13 b, so that the container C in the storage lane 2 Transport can be carried out smoothly and efficiently.

  For example, when the cart 9 receives the container C from the delivery platform 5 in the seaside delivery area 3 and transports it to one of the yard cranes 6, the cart 9 self-travels in the clockwise direction on the ring road 10. Specifically, the cart 9 self-travels on the outward path 11 from the sea side to the land side, passes the container C to the yard crane 6, moves to the return path 12 from the outbound path 11 by the moving unit 13 b, and reaches the land on the return path 11. Self-propelled from the side toward the sea side and returned.

At this time, in the outward path 11, the cart 9 is self-propelled from the sea side to the land side, and the moving part 13 b returns to the return path 12.
On the other hand, since the cart 9 is self-propelled from the land side to the sea side on the return path 12 and returns to the outbound path 11 by the moving unit 13a, the carts 9 circulate in the annular path 10, so the cart 9 The waiting time is short, and the containers C can be transported one after another.

  When the container C is received from the yard crane 6 and transported to the delivery platform 5 in the land-side delivery area 4, first, the cart 9 self-propels the return path 12 from the land side to the sea side, and then moves from the return path 12 to the outbound path 11 by the moving unit 13a. To the land side, the container 11 receives the container C from the yard crane 6 and transports it to the delivery platform 5 in the land side delivery area 4.

  Conversely, when the container is received from the delivery platform 5 in the land-side delivery area, and when the container C is received from the yard crane 6 and transported to the delivery platform 5 in the sea-side delivery area 3, the cart 9 is opposite to the above. That is, it self-travels in the counterclockwise direction on the circular road 10.

  The moving parts 13a and 13b operate as described above, and the traveling path of the cart 9 can be changed to the annular path 10, and the cart 9 can carry the containers C one after another. Therefore, the yard crane 6 straddling the storage lane 2 and moving in the longitudinal direction of the storage lane 2 can be in charge of lifting and lowering the container C, and the cart 9 can be in charge of transporting the container C in the storage lane 2. Therefore, the containers C in the storage lane 2 can be transported efficiently, and the containers C can be transported one after another. Thereby, the cargo handling efficiency of the container terminal 1 can be improved.

  In addition, the distance between the forward path 11 and the return path 12 can be narrowed compared to the case where an annular traveling path is provided at both ends of the forward path 11 and the return path 12, so that it is arranged in the container terminal 1. The number of storage lanes 2 that can be increased can be increased.

  In this embodiment, a container terminal of a known technique can be used except for the moving unit 13 described above. Further, when one traveling path 6b of the yard crane 6 is arranged between the forward path 11 and the return path 12, the storage lane 2, the forward path 11, the one traveling path 6b of the yard crane, and the return path 12 can be arranged in this order. The arrangement space can be reduced. Thereby, when the some storage lane 2 is arranged, the space | interval of the adjacent storage lane 2 can be shortened and more storage lanes 2 can be installed. This arrangement is not limited to the above arrangement. For example, it may be in the order of the storage lane 2, one traveling path 6 b of the yard crane 6, the forward path 11, and the return path 12.

  Next, the operation of carrying the cart 9a that is not self-propelled to the broken vehicle path 17 will be described with reference to FIG. Here, the cart 9a is a cart that is not capable of self-propelling, and the cart 9b is a cart that is capable of self-propelling. In this embodiment, the operation of causing the cart 9a that has become unable to run on the forward path 11 to enter the broken vehicle path 17 will be described as an example. However, the present invention is not limited thereto, and the cart 9a is not allowed to run on the return path 12. It can also be applied to old carts.

  First, as shown in FIG. 7 (a), the cart 9a, which has become unable to self-propell on the forward path 11, is capable of self-propelling, and the cart 9b that follows the cart 9a pushes toward the moving unit 13 to self-propell. (Step S11). Next, the control device 18 moves the first wheel stopper 16a to secure a traveling path to the broken vehicle road 17 (step S12). At this time, the control device 18 detects that the cart 9a has failed and is unable to run on its own, until the cart sensor 19a does not detect the cart 9a, and until the cart 9a is retracted to the failed vehicle path 17. The cart 9b may be controlled not to be detected by the cart sensor 19a.

Next, as shown in FIG. 7 (b), the cart 9b keeps pushing the cart 9a and does not stop at the intersection of the forward path 11 and the connection path 14 but is connected to the forward road 11 17 is entered (step S13). Next, the cart sensor 19b detects the cart 9a (step S14).

  Next, as shown in FIG. 4 (c), the self-running direction of the cart 9b is reversed, and the self-running from the land side to the sea side is carried on the main road 14a (step S15). It moves between the forward path 11 and the return path 12 in operation.

  According to this operation, even if the cart 9 breaks down on the outward path 11 or the return path 12, the cargo handling operation of the container terminal 1 can be continued without stopping. In addition, if the broken vehicle road 17 is configured to charge the cart 9a with electric power, electric power can be supplied to the cart 9a that has become incapable of self-running due to insufficient electric power so that the cart 9a can run on its own.

  Next, a container terminal according to a second embodiment of the present invention will be described with reference to FIG. The storage lane 2 of the container terminal 1 according to the first embodiment includes a carry-in container area 2a and a carry-out container area 2b. In addition to both ends of the forward path 11 and the return path 12, the carry-in container area 2a and the carry-out container area The moving part 13c is provided in the vicinity on the extended line 2c of the boundary with 2b.

  The carry-in container area 2a is an area in which the foreign chassis 8 is carried from the outside of the container terminal 1 and a container loaded on the ship is arranged. The unloading container area 2 b is an area in which containers that are unloaded from the ship and are carried out by the foreign chassis 8 to the outside of the container terminal 1 are arranged. Handling efficiency can be improved by roughly distinguishing the storage lane 2 from the sea side into the carry-in container area 2a and the land side from the carry-out container area 2b.

  If the moving part 13c is provided in addition to the both ends of the forward path 11 and the return path 12, the circular path 10 and the carry-in circular path 10a in which the cart 9 self-propells in the carry-in container area 2a with the moving part 13c as a boundary. The cart 9 can be divided into a carry-out annular path 10b that self-propells in the carry-out container area 2b.

  However, when the traveling path 6b of the yard crane 6 is a rail, the connection path 14c and the traveling path 6b of the yard crane 6 intersect with each other, so that the forward path 11 and the connection path 14 intersect with each other. It is configured without disturbing either run. Moreover, what is necessary is just to form so that the connection path 14c may be embed | buried under the ground, when the traveling path 6b is other than a rail.

  For example, if a container previously loaded from the outside is stored in the loading container area 2a and a container to be discharged outside is stored in the loading container area 2b, the container is loaded on the ship or is carried out by the foreign chassis 8. In this case, since the cargo handling work is performed in the carry-in container area 2a or the carry-out container area 2b, when the work is performed on one side, the work is not performed on the other side.

  So, according to said structure, when loading a container on a ship, or when carrying out with the foreign chassis 8, the cart 9 self-propelled by either one of the carrying-in cyclic path 10a or the carrying-out cyclic path 10b in cyclic | annular form. The traveling distance of the cart 9 can be shortened. Thereby, while shortening the time for the cart 9 to travel in a ring shape, the number of carts 9 can be reduced, and the cost of the container terminal 1 can be reduced.

  For example, when the container loaded from the outside is stored in the loading container area 2a and the container loaded / unloaded from the ship is stored in the loading container area 2b, the above-described configuration is the same circular path as in the first embodiment. 10 can be used.

  In this embodiment, the moving part 13c is provided in the vicinity of the extension line 2c. However, a plurality of moving parts 13c may be provided in addition to the vicinity of the extension line 2c.

  Next, a container terminal according to a third embodiment of the present invention will be described with reference to FIG. The container terminal of this embodiment is provided with a rotating self-propelled device 40 as shown in FIG. 9A in place of the main traveling device of the cart 9 of the container terminal and the traveling device for connection path of FIG. Moreover, this container terminal is provided with the raising / lowering apparatus 44 in the part which the outward path 11 and the connection path 14 cross | intersect, as shown in FIG.9 (b).

  The rotating self-propelled device 40 includes a shared wheel 41, a wheel rotating device 42, and a motor 43. The wheel rotation device 42 is a device that rotates the shared wheel 41 around the vertical axis, and rotates so that the flange portion 41b of the shared wheel 41 is inside the wheel portion 41a. A well-known technique can be used for the rotating mechanism, and the description thereof is omitted.

  The lifting device 44 is a device that lifts the cart 9 in the vertical direction. In this embodiment, a device for lifting the cart 9 provided at the intersection of the forward path 11 and the connection path 14 and the return path 12 and the connection path 14 will be described as an example. Good.

  The operation of this container terminal will be described. First, when the cart 9 that has been traveling on the outward path 11 from the sea side to the land side comes into contact with the first wheel stopper 16a (step S21), the cart sensor 19a detects the cart 9 (step S22). Next, the control device 18 stops the cart 9 (step S23).

  Next, as shown in FIG. 9B, the control device 18 lifts and holds the cart 9 with the elevating device 44 (step S24). Next, as shown to (a) of FIG. 9, the control apparatus 18 rotates the wheel rotation apparatus 42 around a vertical axis line, and rotates the common wheel 41 (step S25). Next, the control device 18 lowers the cart 9 with the lifting device 44 and places the shared wheel 41 on the connection path 13 or the flange rail 15 (step S26).

  Next, the control apparatus 18 drives the rotation self-propelled apparatus 40 (step S27). At this time, since the rotating direction is different between the clockwise shared wheel 41 and the counterclockwise shared wheel 41 in FIG. 9A, the motor 43 is controlled so as to be in the same direction.

  Next, when the cart 9 travels on the connection path 14 (step S28), the cart 9 comes into contact with the second wheel stopper 16b (step S29). Next, when the cart sensor 19a detects the cart 9 (step S30), the control device 18 then stops the cart 9 (step S31). Thereafter, as described above, the control device 18 rotates the common wheel 41 to change the self-running direction, and self-runs the return path 12 to complete.

  According to this configuration, the self-running direction of the cart 9 can be changed only by rotating the common wheel 41.

  Next, a container terminal according to a fourth embodiment of the present invention will be described with reference to FIG. In this container terminal 50, the container terminals according to the first embodiment are arranged side by side in a direction orthogonal to the sea-land direction, and two return paths 51a and 51b are shared between the storage lane 2c and the storage lane 2d. It is the structure which arranges.

Further, the container terminal 50 includes moving parts 53 at both ends of the forward paths 51 a and 51 b and the return path 52. The moving portion 53 includes a connection path 44a that intersects the forward path 51a, a flange rail 55a provided at the intersecting portion, a connection path 44b that intersects the forward path 51b, a flange rail 55b provided at the intersecting portion, and A flange rail 55c provided at an intersecting portion of the return path 52 is provided.

  In addition, although not shown, first wheel stops are provided on the end sides of the forward path 51a, the forward path 51b, and the return path 52, and second wheel stops are provided on both end sides of the connection path 54a and the connection path 54b. In particular, the second wheel stopper provided on the end side of the return path 52 is a movable type.

  According to the above configuration, since the return path 52 can be shared, the space between the storage lane 2c and the storage lane 2d can be narrowed. Thereby, many storage lanes 2c and 2d can be provided in the container terminal 50.

  In the container terminal of the present invention, the movement between the forward path and the return path adjacent to the storage lane is carried out by the self-propelled carriage, so that the movement between the forward path and the return path is required promptly and highly sophisticated operation is required. In particular, a storage lane having a longitudinal direction in the sea-land direction can be improved by enabling the transport cart carrying the container to self-propelled in a ring and improving the cargo handling efficiency. It can be used for the container terminal provided.
