[ problem to be solved by the invention ]

In the conventional transportation method, since thousands of containers are unloaded by a plurality of gantry cranes, there is a problem that it takes a long time to complete the transportation of all the containers. While the container is lifted by the gantry crane, set at a predetermined position of the container ship, and then returned to the waiting position of the transfer vehicle, the next transfer vehicle with the container mounted thereon must wait at the waiting position. Since thousands of containers are transported, the waiting time is long, and the entire loading and unloading time is also long. In addition, since a skilled technique is required to operate the gantry crane, there is a problem that there is a limitation on an operator.

Further, since a plurality of containers are stacked, when a container which is not to be transported is loaded on a container to be transported in a port, there is a problem in that a stacking process of temporarily transporting an upper container, transporting a lower container, and newly installing an upper container is performed, and thus the entire loading/unloading time is increased.

In addition, in order to improve the loading and unloading capacity of a port or to construct a new container terminal, it is necessary to add or newly install a gantry crane, but a huge initial investment such as a purchase cost of the gantry crane or a maintenance cost of a foundation capable of supporting the installation of the gantry crane is required. Further, the container carrier can only enter the port where the gantry crane is installed in conformity with the size thereof, so that there is a problem in the conventional transportation system that the port where loading and unloading can be performed is limited, and the logistics efficiency is lowered.

The present invention has been made to solve the above-mentioned problems, and relates to a container carrier that can easily transport containers in a short time, and a method of transporting containers.

[ means for solving the problems ]

In order to solve the above-described problems, a container carrier according to the present invention includes a container installation space, a container installation mechanism, a transfer passage, an inboard ramp, and at least one of a side ramp and a stern ramp, wherein the container installation space is provided in plurality in a full length direction, a width direction, and a height direction of a hull, and is used for installing containers; the container setting mechanisms are respectively arranged in the container setting spaces and are used for setting the containers; the carrying channel is used for the passing of a container carrying device, and the container carrying device is used for carrying the container; the ship inner ramp is used for enabling the container handling device to move along the height direction of a ship body; at least one of the side ramp and the stern ramp is used for the container handling device to move inside and outside the ship body.

The present invention is a container transfer method for transferring a plurality of containers into a container carrier, comprising a loading step of loading a container disposed outside a ship into a container transfer device, a transfer step of transferring the container to the container transfer device, a setting step of setting the container, and a moving step of moving the container; in the transfer step, the container is transferred into the container ship by the plurality of container transfer devices; in the setting step, the container is set by container setting mechanisms respectively provided in a plurality of container setting spaces for setting the container; in the moving step, after the setting step, the empty container transfer device is moved to the outside of the ship, and the plurality of container installation spaces are provided in the overall length direction, the width direction, and the height direction of the container transport ship.

According to the above configuration, since the containers are continuously transferred to the plurality of container installation spaces provided in the hull by the plurality of container transfer devices, the process of transferring the containers can be shortened, and the waiting time for transferring can be eliminated or shortened. Thus, the time for loading and unloading the container can be shortened.

Further, according to the present invention, since the container can be individually installed in the container installation space, for example, by moving the position of the container in the sea using the container transfer device installed in the ship, the container transfer work at the time of loading and unloading can be omitted, and the time required for loading and unloading can be shortened.

Further, according to the present invention, since the loading and unloading work can be sufficiently performed without requiring equipment such as a gantry crane for installing a container and by providing equipment for stopping the container transfer device by moving the container transfer device to and from the stern ramp or the side ramp inside and outside the hull, the container can be loaded and unloaded to and from the conventional port while suppressing initial investment.

Further, according to the present invention, since the container is transported to the container transporting device, a large-sized mechanism such as a gantry crane is not required, and there is no technical limitation on the operator.

In addition, it is preferable that the container setting mechanism is a container support member which is provided in the container setting space and sets the container.

Preferably, the container installation space has a bottom, a plurality of pillars, and a top, and the container support member has a plurality of projecting portions projecting inward from each of the plurality of pillars.

According to the structure, the container can be easily arranged in the ship only by arranging the container on the container supporting piece.

[ Effect of the invention ]

According to the container ship and the method for transporting the container of the present invention, the container can be easily transported in a short loading and unloading time.

Detailed Description

Next, a container carrier, a container transfer system, and a container transfer method according to embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in fig. 1 and 2, a container ship 100 according to the present embodiment is a ship for transporting a plurality of containers C.

The container ship 100 mainly includes a main body 1, a living unit 2, and a propulsion unit 3. The main body 1 occupies most of the hull, and is provided with a plurality of container installation spaces 10 for installing containers C. The living section 2 is a part of a living area where crews live. The propulsion unit 3 is a part serving as a driving source for propelling the hull. The propulsion unit 3 may be driven by a battery, or may be driven by a propeller (turbine) and an engine (engine).

On the side of the hull, a connection inclined passage 5 (stern ramp 5A and side ramp 5B) for connecting the inside and outside of the ship is provided. The stern ramp 5A and the side ramp 5B are entrances and exits for the container transfer device 30 described later to enter and exit the hull. When loading and unloading the container C, the stern ramp 5A and the side ramp 5B are lowered to be connected to the dock, and the stern ramp 5A and the side ramp 5B are folded when the ship is going out. In the present embodiment, the stern ramp 5A and the side ramps 5B are provided, but the number thereof is not limited. May be provided with at least one of the stern ramp 5A and the side ramp 5B.

As shown in fig. 8, an inboard ramp 6 is provided inside the main body 1. The ship-side ramp 6 is a road for raising and lowering a container transfer device 30, which will be described later, on an upper deck and a lower deck. The inboard ramp 6 communicates with a transfer passage 25 of each deck described later. In the present embodiment, the inboard ramp 6 is provided at one location, but may be provided at a plurality of locations, or may be provided at any position.

As shown in fig. 1 and 2, the container installation space 10 is a space for installing the containers C, and a plurality of containers are installed inside the main body 1 in a grid shape in the entire length direction, the width direction, and the height direction. The number of the container arrangement spaces 10 depicted in fig. 1 and 2 is merely an example, and the number thereof is not limited. As shown in fig. 3 and 4, the container installation space 10 is formed by being surrounded by a plurality of columns 18, a bottom 21, and a top 23, which may be formed by a part of the hull structure.

The hull has a bottom portion 21 and a top portion 23 extending in the entire length direction and the width direction, and a plurality of struts 18 are provided to connect the bottom portion 21 and the top portion 23. Between adjacent struts 18 there is provided a projection 24. The container installation space 10 is not provided with a partition wall around but communicated. That is, the adjacent container installation spaces 10, 10 communicate with each other.

The bottom 21 forms a lower part of the container installation space 10 and is a part for passing a container transfer device 30 described later. The bottom 21 also serves as the top of the container installation space 10 of the next floor. The four columns 18 constituting the container installation space 10 are respectively formed with projecting portions 24 projecting inward. The four protruding portions 24 support four corners of the container C. In the present embodiment, the containers C are supported by the four extending portions 24, but the number is not limited as long as the containers C can be supported.

Since the container C is supported by the projecting portions 24, the shortest distance between the projecting portions 24, 24 is shorter than the dimension in the full length direction and the dimension in the width direction of the container C. In the present embodiment, the cross-sectional shape of the extension portion 24 is formed in a rectangular shape in the overall length direction and a triangular shape in the width direction, but may be formed in other shapes as long as the container C can be installed. The four protruding portions 24 constitute a "container support (container setting mechanism)" for setting the container C. The roof 23 is a portion arranged in parallel with the upper surface of the container C with a gap. The roof 23 also serves as the bottom 21 of the container installation space 10 of the previous floor.

The upper surface of the roof 23 serves as a deck of the bottom 21 of the container installation space 10 serving as the upper floor, and on the lower surface of the roof 23, keels G1 (keels) and ribs H1 (longitudinal beams and oblique beams) are disposed with sufficient space from the upper surface of the container C to support the deck and penetrate longitudinally in the entire length direction, and the ribs H2 disposed in the width direction to support these keels G1 and ribs H1 are disposed with equal space from the columns 18. In general, in a ship provided with an inboard ramp, structural members such as a strut and a partition wall are reduced as much as possible in order to improve the degree of freedom in carrying cargo in and out, and as a result, a keel and a rib for supporting a deck are increased in size, and a space in the height direction in the ship is sacrificed.

In this regard, in the present embodiment, since the columns 18 for installing containers are densely provided in a lattice shape in the ship interior, the height of the keel G1 and the height of the ribs H1, H2 can be reduced compared to a general ship provided with an inboard ramp, and the space in the ship can be more effectively used, or the height of the ship itself can be kept low by minimizing the distance from the bottom 21 to the top 23 of the deck layer on which the containers are installed. Further, since the container transfer device 30 described later has a mechanism that is movable in the entire length direction and the width direction, it is not necessary to reduce the number of structural members such as the support column, and the support column 18, the keel G1, and the ribs H1 and H2 may be disposed so as not to interfere with the movement path.

The space below the extension 24 in the container installation space 10 serves as a conveyance path 25. The conveyance path 25 is a space for passing a container conveyance device 30 described later. The shape and height position of the projecting portion 24 (height dimension of the conveyance path 25) are formed so as not to interfere with the container conveyance device 30 provided with the container C. The conveyance passage 25 is formed continuously in a straight line in the entire length direction and the width direction of the hull. That is, the container transfer device 30 can move in the entire length direction and the width direction of the hull through the transfer path 25, and can efficiently reach the stern ramp 5A or the side ramp 5B.

Fig. 5 is a perspective view showing the container transfer device according to the present embodiment. As shown in fig. 5, the container transfer device 30 is a device for transferring a container C from the container terminal CT to the container ship 100 via the stern ramp 5A or the side ramp 5B, the intra-ship ramp 6, and the transfer passage 25. The container transfer device 30 is a device that returns the container C to the container terminal CT in an empty state through the transfer passage 25, the inboard ramp 6, the stern ramp 5A, or the side ramp 5B after the container C is set in the container ship 100.

In the present embodiment, the container transfer device 30 is operated in an unmanned manner, but may be operated in a manned manner. In the present embodiment, the container transfer device 30 is operated by a battery, but may be operated by another drive source.

The container transfer device 30 includes a main body 31, a plurality of tires 32, a control unit 33, and a lifting unit 34. The body 31 has a width and a length capable of carrying the container C. A battery or the like for driving the container transfer device 30 is mounted inside the main body 31. The control unit 33 is a part for controlling the container transfer device 30, and includes a communication unit capable of transmitting and receiving a control signal to and from the control device 50.

The lifting unit 34 is a part for loading the container C and is a part capable of lifting and lowering the container C with respect to the main body 31. That is, when the lifting unit 34 is lifted, the container C is lifted by about several tens of centimeters, and when the lifting unit 34 is lowered, the container C returns to the original height position. The original height position is set to be lower than the upper surface of the extension portion 24. The lifting portion 34 has a total length dimension and a width dimension shorter than respective shortest distances between the protruding portions 24, 24 (between the total length direction and the width direction).

As shown in fig. 6, the case where the container C is set in the container setting space 10 (setting step) means that the lifting unit 34 is moved into the container setting space 10 in a raised state, and the container transfer device 30 is stopped. Then, the container C can be set on the four projecting portions 24 simply by lowering the lifting portions 34. More specifically, the lifting portion 34 is lowered until the upper surface of the lifting portion 34 is located below the upper surfaces of the projecting portions 24, and the container C is set on the four projecting portions 24.

The container transfer device 30 may be configured to rotate in the left-right direction in addition to the forward or rearward direction. For example, the carrier may be configured to be movable in a straight transverse direction in addition to forward and backward movements, such as a carrier (carrier vehicle or carrier robot) used for material handling. In addition, a plurality of the carrying devices may be used to carry one container C.

Next, a container conveying system 200 and a container conveying method according to the present embodiment will be described. As shown in fig. 7 and 8, the container handling system 200 is a system for automatically handling a plurality of containers C loaded on a container terminal CT to a container carrier 100. As shown in fig. 7, the handling system 200 has a plurality of container handling devices 30(30A, 30B · 30n), a yard crane 40 and a control device 50.

Here, the case where the containers C1, C2, C3, and C4 loaded on the container terminal CT in fig. 8 are transported to the container installation spaces 10A, 10B, 10C, and 10D provided in the ship will be described as an example.

As shown in fig. 7 and 8, the control device 50 is provided in a control room N provided in the container terminal CT. The control device 50 includes an input unit 52 such as a computing unit 51(cpu (central Processing unit)), a keyboard, a touch panel, and the like, a display unit 53 such as a monitor, a display, and the like, a storage unit 54 such as an ssd (solid State drive), an hdd (hard Disk drive), a ram (random Access memory), and a rom (read only memory). The control device 50 includes a communication unit that can transmit and receive control signals to and from the respective container handling devices 30. The storage unit 54 stores, for example, a conveyance program 55.

The transfer program 55 is a program for transferring each container transfer device 30 to a predetermined container installation space 10 set in advance. The container installation space 10 in the hull where each container C loaded on the container terminal CT is installed is set in advance. As shown in fig. 8, for example, it is preset that a container C1 is installed in the container installation space 10A, a container C2 is installed in the container installation space 10B, a container C3 is installed in the container installation space 10C, and a container C4 is installed in the container installation space 10D.

In the transport system 200, the control device 50 executes the transport program 55, and as shown in fig. 9, a loading step (S1), a transport step (S2), a setting step (S3), and a moving step (S4) are performed.

The loading step (S1) is a step of loading the container C on the container transfer device 30 by the yard crane 40. The container handling device 30 waits at a container receiving position 40a set below the yard crane 40. The container C1 is lifted by the yard crane 40, the container C1 is loaded on the container transfer device 30, and the container transfer device 30 is started when the container transfer device 30 and the container C1 are locked.

In the present embodiment, the yard crane 40 is operated by the operator to load the container C on the container transfer device 30, but the present invention is not limited to this. For example, it may be: the yard crane 40 is provided with a reading unit that reads container identification information (a container number, a two-dimensional code (a barcode, a QR code), and the like) given to the container C, and performs a predetermined lifting operation of the container C and a loading operation of the container C to the container transfer device 30 in an unmanned (automatic) manner.

The transfer step (S2) is a step of transferring the container C to the preset container installation space 10 using the container transfer device 30 in which the container C is loaded. That is, in the case of the container C1, the transportation step is a step of transporting the container C1 from the container receiving position 40A to the container installation space 10A via the stern ramp 5A. A travel path of the container transfer device 30 is set in advance, and the container transfer device 30 travels automatically (unmanned) along the travel path.

First, the container transfer device 30 transfers the container C from the container receiving position 40a to the predetermined transfer passage 25. In the case of the container C1, the container transfer device 30 passes through the transfer lane 25 corresponding to the container installation space 10A (for example, N-th transfer lane from the left in N levels).

Next, the container transfer device 30 is stopped in the predetermined container installation space 10. In the case of the container C1, the container transfer device 30 stops at the center of the container installation space 10A (the state of fig. 6).

The installation step (S3) is a step of installing the container C by the container installation mechanisms (four protruding portions 24) respectively provided in the container installation spaces 10. When the container transfer device 30 reaches the container installation space 10, the lift unit 34 is lowered. Accordingly, the container C is set in the extension portion 24. In the present embodiment, the container C1 is provided in the extension portion 24 of the container installation space 10A.

The moving step (S4) is a step of moving the empty container transfer device 30 to the outboard side after the installation step. In the moving step, the container transfer apparatus 30 passes through the transfer passage 25 without restriction in the entire length direction or the width direction thereof when the lift portion 34 is lowered to the lowest position (the container C is set), and returns to the container receiving position 40a again via the ship's inner slope 6 and the side slope 5B. The empty container transfer devices 30 can pass through a different path from the container transfer devices 30 in the loaded state, and thus can continuously transfer the containers C like the automobiles of the automobile transport ships.

A travel path from the side slope 5B to the container receiving position 40a is also set in advance, and the container transfer device 30 travels along this travel path. Up to this point, there are 1 operation process of the container transfer device 30. In the present embodiment, this operation is continuously performed using a plurality of container transfer devices 30(30A, 30B · 30 n). Accordingly, the containers C2, C3, C4 can be continuously transported to the container installation spaces 10B, 10C, 10D, respectively.

When the container C installed in the container installation space 10 is transported from the ship interior to the ship exterior, the empty container transfer device 30 is moved to the predetermined container installation space 10 and stopped in a state where the lift unit 34 is lowered. Then, the lifting portion 34 is raised, thereby separating the container C from the protruding portion 24. In this state, the container C can be transported to the outside of the ship by the container transporting apparatus 30 traveling through the transport path 25.

In addition, it may be: a reading unit and a sensor are provided in the container installation space 10, and identification information (a container transfer device number, a container number, a two-dimensional code (a barcode, a QR code), and the like) given to each container transfer device 30 or each container C is read to match the container C with a transfer destination. Further, a sensor may be provided to determine whether the container handling apparatus 30 has reached a predetermined position.

According to the container carrier, the container transfer system, and the container transfer method of the present embodiment described above, the transfer operation process is continuously performed by the plurality of container transfer devices 30, and thus the loading/unloading time can be significantly reduced. That is, in the prior art, it is necessary to stop the transport vehicle or the like on the container ship 100 and wait until the container C is lifted into the ship, but in the present embodiment, since the transport vehicle or the like can enter the ship with the container C loaded, the waiting time can be eliminated or shortened.

Further, since the container C is transported by the container transporting apparatus 30, the gantry crane is not required. Accordingly, initial investment such as purchase cost of the gantry crane and maintenance cost of the foundation on which the gantry crane is installed can be carried out, and thus equipment cost can be reduced. In addition, although the container carrier can only enter a port where a gantry crane is installed according to the size of the container carrier in the related art, the present embodiment is not limited to this, and the logistics efficiency can be improved if the present embodiment includes a device for allowing the container handling apparatus 30 to travel to and from the stern ramp 5A or the side ramp 5B inside and outside the hull to stop.

The container installation space 10 is formed by a plurality of columns 18, a bottom 21, and a ceiling 23, and the container installation mechanism (container support) is formed by four projecting portions 24 projecting inward from the respective columns 18. According to the above configuration, the container C can be easily installed in the ship only by installing the container C in the extension portion 24. In addition, according to the installation process of the present embodiment, the container C can be installed in the extension portion 24 only by lowering the lifting portion 34 from the state where the container C is lifted up, and therefore, the installation work can be easily performed in a short time. Further, by simply raising the lifting unit 34 from the lowered state, the container C set in the ship can be easily transported to the outside of the ship in a short time.

As shown in fig. 3 and 4, the lifting portion 34 has a shorter overall length and a shorter width than the respective shortest distances between the projecting portions 24 and 24 (between the overall length and the width). In other words, the container transfer device 30 is configured to be movable in the full length direction and the width direction between the container installation spaces 10 and 10 adjacent to each other in the full length direction and the width direction. Accordingly, in a state where the container C is loaded and the lifting portion 34 is lifted, the container transfer device 30 can be driven in both the overall length direction and the width direction between the container installation spaces 10 and 10. Accordingly, the conveying efficiency can be further improved.

Further, in the conventional art, since the containers C are stacked in a plurality of stages, when the containers C to be transported in the berth are loaded with containers that are not to be transported, there is a problem in a transfer process of transporting the containers on the upper stage temporarily, transporting the containers on the lower stage, and resetting the containers on the upper stage. However, according to the present embodiment, since the container transfer device 30 can travel in the overall length direction and the width direction on the transfer passage 25, a predetermined container C can be transferred overboard only by performing the pile transfer operation for securing the container transfer path. Accordingly, the efficiency of the handling operation can be improved.

Further, according to the present embodiment, since the container installation space 10 can install the containers C individually, for example, by moving the position of the containers C in the sea using the container transfer device 30 mounted in the ship, the container transfer work at the time of loading and unloading can be omitted, and the time required for loading and unloading can be shortened. Further, according to the present embodiment, since the container C is transported by the container transporting apparatus 30, a large machine such as a gantry crane is not required, and the technical limitation of the operator is not required.

While the embodiments of the present invention have been described above, design changes can be made as appropriate without departing from the spirit of the present invention. For example, the container installation mechanism may be configured by engaging or disengaging an engaging portion formed in the container C with or from an engaged portion formed in the container installation space 10. The container installation mechanism may be configured to load and unload the container C into and from the container installation space 10 by using a magnetic force.

In addition, the following control may be performed: after the container C outside the ship is set in the container installation space 10, the empty container transfer device 30 is moved to another container installation space 10, and the container C at that position is carried out outside the ship.

The transportation program 55 is only an example, and the container C may be transported by using another control method. The communication between the control device 50 and the container transfer device 30 may be performed through a communication network such as the internet or an Intranet (Intranet). That is, the control device 50 can acquire and execute the transport program by reading the transport program from the recording medium or receiving the transport program via the communication network. In addition, it may be: each container transfer device 30 is provided with a reading unit that associates identification information (a container number, a two-dimensional code (barcode, QR code, etc.)) given to each container C with identification information (a container transfer device number, a two-dimensional code (barcode, QR code, etc.)) given to the container transfer device 30, and stores the identification information in the storage unit 54 together with a travel record of the container transfer device 30. This makes it possible to easily manage the transportation of the container C.
