DETAILED DESCRIPTION OF THE INVENTION

[0069] One embodiment of the invention is a mine storage container 8 for a mine handling system. By a container is understood a module, container module, modular unit, or a similar construction made as units for transport and/or storage. Such units or containers may be stacked and connected. The word container will be used in this application, but the words module or modular unit could also have been used, as they are understood to be equivalent. A mine storage container 8 is illustrated in FIG. 1 and comprises a top frame 12, a bottom frame 13, two side frames 19, a first end frame 10, and a second end frame 11. These frames are connected and constitute the storage container frame. All frames are rectangularly shaped such that the container has a rectangular shape. The storage container further comprises conveyors 16, positioning means 22, and guiding means 24.

[0070] The frame 20 of the storage container 8 is preferably made in standard sizes of cargo/shipping containers like the ISO 668 standard. Containers following the ISO standard are 2,438 m wide and have different length, where the normal lengths are 6,058 m and 12,116 m but containers can have other length as well. The main heights of the ISO standard are 2,438, 2,591 m and 2,896 m. In other embodiments the container frame 20 sizes are designed for special purposes like specific ships. The container frame is usually made of steel but can also be made of different metals or alloys like aluminum.

[0071] All sides of the containers described may be closed or open. A closed side could have a wall made of metal, plastic, cloth, or another material for making walls for a container. In the ends there can be doors as mines will be conveyed in and out of the end frames of the containers. The top and the bottom of the containers can be sealed permanently if desired.

[0072] The conveyors 16 are fastened to the frame 20 such that the conveyors are supported by the frame and fixed such that the conveyors can support a plurality of mines. The conveyors may be secured in multiple layers in order to store mines 18 in multiple layers. The conveyors 16 may be fastened with an equal spacing from the bottom frame of the storage container 8 to the top frame of the storage container 8. This spacing ensures that mines can be placed and kept at one conveyor 16 and other mines can be stored on another conveyor vertically above the first mines 18.

[0073] Some embodiments of this invention are designed to store and launch mines having a shape of a trapezoid or a cylinder. Other embodiments of the mine laying system may be designed and used for other types of mines with different shapes. A mine normally weighs between 100-2000 kg.

[0074] In order to transport mines in and out of a storage container 8, conveyors 16 are used. A conveyor is a well-known transporting device for moving articles along a path. The conveyors 16 used in this invention can be chain conveyors, roller conveyors, belt conveyors or a similar type of conveyors. When it is written that a conveyor is used, it could also be a combination of conveyors like the first part of a conveyor is a belt conveyor and the second part is a chain conveyor. Another variant may be a chain and a roller conveyor combined in one conveyor. All conveyors may have guiding means for fixating the mines to the conveyor.

[0075] In FIG. 1 a chain conveyor 16 is shown. By a conveyor 16 is understood a system that can transport articles placed on the conveyor along a path. This invention can have one conveyor extending from one side of the container to the other side of the container, two conveyors placed side by side from one side of the container to the other, or more depending on the size of the mines for storing. In FIG. 1 two conveyors 16 are placed side by side to hold mines in two rows along the length of the storage container 8, the length axis going from the first end frame 10 of the storage container 8 to the second end frame 11. The chain conveyor 16 has two chains i.e. one in each side of the conveyor, which are driven by a motor 14. The motor 14 could e.g. be electric and therefore power to drive it is needed. This power may be provided by an external cable being connected to the container such that the container can move mines automatically by activating motors 14. The mines are placed in contact with the two chains on the conveyor 16, such that when the chains are activated the mines follow the movement of the chains. If the storage container 8 has been tilted, mines could glide down the chains. To prevent this, positioning means are attached along the chain in each side of the conveyor, such that there is a small structure extending as a protrusion placed between each mine in order to push the mines from one end to the other of the storage container 8 when the conveyor is activated and when the conveyor is passive prevent the mines from gliding or slipping. If the conveyor were made with rollers, the rollers would be driven by the motor 14 and the friction between the rollers and the mines would ensure the mines would stay in place when the rollers were not activated and would follow the rollers when the rollers were activated. The conveyors shown in FIG. 1 are designed such that there are four layers of two conveyors. This could be any number of layers depending on the height of the container and the mines.

[0076] A view of a storage container 8 from the second end frame is shown in FIG. 2. One of the chain conveyors 16 comprises two chains 17. The chains 17 have positioning means 22 fastened on the chain 17 to ensure that mines 18 can be transported along the chains 17 when the chains 17 are activated by a motor 14. The positioning means 22 further have the function to keep the mines in place during transport and storage as the positioning means 22 secure the mines 18 in the length direction of the storage container 8. The length direction of a container is the direction between two end frames of the container. To secure the mines 18 in the two other directions, the first direction going from one side frame of the container to the other side frame of the container, and the second direction going from the top frame to the bottom frame of the container, the storage container has guiding means 24 vertically above the conveyor 16 and along the length direction. These guiding means 24 ensure that the mines 18 will be fixated when the storage container 8 is moved during loading/transport or movement during storage on a ship in high seas.

[0077] Multiple storage containers 8 can be connected such that the first end frame 10 of the storage container 8 is connected to the second end frame 11 of the other storage container 8 using e.g. twist locks. Containers can also be connected by fastening the containers to the floor of the deck side by side. When two storage containers 8 are connected, mines 18 from one container can be transferred to the other container without the use of connection tracks or support that needs to be installed between the conveyors 16. To ensure that the mines do not get stuck or drop down in between the two conveyors in the respective containers, all conveyors in the storage container 8 extend from the first end frame 10 of the storage container 8 to the second end frame 11 of the storage container 8 meaning that the ends of the conveyors 16 in the storage container 8 are very close to the ends of the container, this could be understood as under 5 , cm, 10 cm, 15 cm, 20 cm, or under 25 cm from the end of the conveyor 16 and until the second end frame 11 of the container. This will prevent mines 18 from falling or getting stuck in between two storage containers 8. In one embodiment of the invention, a supporting structure like a roller is added to each end of each conveyor 16 for supporting the mines 18 when transferred from one storage container 8 into another storage container 8.

[0078] An illustration of a launch container 40 according to the invention is shown in FIG. 3. The launch container comprises a top frame 54, a bottom frame 47, two side frames 45, a first end frame 41, and a second end frame 43. All frames are rectangularly shaped such that the container has a rectangular shape. These frames are connected or integrated and constitute the storage container frame. The side frames may be completely open or have a door that can be opened at a position where an operator can handle the mines just before launching. Preferably the launch container has the same height and width as the storage container in order to be able to connect the containers in a simple way and the containers can be densely packed. The launching container comprises a transport conveyor 46 and the transport conveyor 46 has positioning means to ensure that mines 18 are moved when the transport conveyor 46 is activated. The transport conveyor could be chain conveyor, roller conveyor, belt conveyor or any standard conveyor for transporting items. For the chain transport conveyor, the mine would rest on the chains and friction between the mine and the chains ensure that the mines follow the chain. If the friction is not enough for the mines to follow the movement of the transport conveyor, positioning means 22 fastened to the chains are placed between each mine such that when seen from the second end 43 of the launch container, the cross-section of the mine overlap with the cross-section of the positioning means. A mine cannot move past a positioning means 22 in the length direction of the launch container, thus fixating mines completely on the launch conveyor 46. All conveyors in all containers may have positioning means 22. The mines are ready for inspection and preparation by the operators or a robot when the mines have been transported to the transport conveyor. After a last inspection of preparation the mines are ready to be laid or launched from the ship. The operators usually prepare the mines for being activated by pulling out a security split. This operation may in another embodiment be automatic and controlled by servo motors such that no operators are needed. The transport conveyor 46 has transport conveyor guiding means such that the mines 18 only can move along the length direction of the launch container which is understood as going from the first end 41 of the launching container 40 to the second end frame of the launching container 40. Furthermore, the launch conveyor has removable transport conveyor guiding means 56 placed in the middle between the two transport conveyors to make the launching container 40 usable with different types of mines, e.g. mines that are too large to be launched in two lines and thus needs to be launched in one line.

[0079] The frame of the launch container 40 is preferably made in standard sizes of cargo/shipping containers like the ISO 668 standard. Containers following the ISO 668 standard are 2,438 m wide and have different length, where the normal lengths are 6,058 m and 12,116 m but launch containers can have other length as well e.g. a part of the standard length when combined with an elevator container. The main heights of the ISO standard are 2,438, 2,591 m and 2,896 m. In other embodiments the container frame 20 sizes are designed for special purposes like specific ships. The container frame is usually made of steel but can also be made of different metals or alloys like aluminum.

[0080] All sides of the launch container may be closed or opened. A closed side could have a wall made of metal, plastic, cloth, or another material for making walls for a container. The ends of the container may be open such that the container is ready to connect to another container and transport mines in or out, at the ends of the container there may be doors as mines will be conveyed in and out of the end frames of the containers. The top and the bottom of the containers can be sealed permanently.

[0081] In one embodiment of the invention mines may be fastened to a tray that fits on the conveyors in the storage conveyor and the launch conveyor and can be fixated by the guiding means and the positioning means. The tray may be part of the mine or fastened to the mine. The tray will be launched together with the mine. By having removable guiding means in the launching container, multiple mine with different shapes can be transported from a storage container 8 to the ramp 44 safely also when the container is vibrated by e.g. being on a ship in high seas with large waves.

[0082] When mines are launched mines are transported from the transport conveyor 46 to a ramp 44, where the velocity of the mines may be controlled when laying the mines. A ramp 44 and a launch ramp conveyor are used interchangeably in the following. The launch ramp conveyor 44 may comprise free rolling rollers 50 and may further comprise controlled rollers 52. The ramp 44 may also be a belt conveyor or a chain conveyor. The ramp 44 can be divided in two parts, where the first part is pivotable around the end point of the first part and that end point is connected to the second part of the ramp. The second part of the ramp is stationary and connects the transport conveyor and the first part of the ramp. The ramp may only consist of one part that is pivotable around the point where it connects to the transport conveyor. The pivotable part of the ramp can be lowered such that it extends out of the launching container 40 when ready for launching mines, and it can fit inside the launch container when the launch container is transported. The velocity of the mines is controlled by having the first rollers of the ramp 44 being motorized rollers 52 such that the speed of these motorized rollers is controlled. All rollers in the ramp can also be freely rolling and the operator will give mines their initial speed when entering the ramp 44. The initial speed can be very small and the speed at the end of the ramp will then be controlled by the length of the ramp and the angle. When the mines leave the motorized rollers, the angle of travel for the mines is less than horizontal and thus the mines will gain speed due to the gravitational force. The angle of the ramp 44 is controlled by a gear motor or a hydraulic cylinder and thus pivotable around a point inside the launch container. This is to ensure that the mines 18 leave the ramp 44 with a defined and controlled velocity speed and angle. The position of the ship in the water depends at least on how the ship's cargo is stored and the weather, therefore the ship's trim is important for the velocity of the mines when laid from the launching container. Thus, the system uses sensors in a motion reference unit to measure the angle of the ramp/container continuously, such that the correction system can move the ramp to keep the desired angle of the ramp 44 compared to horizontally.

[0083] The launch container 40 may comprise an elevator 42. The elevator comprises an elevator conveyor for transporting and storing mines on the elevator. A motor may control how the elevator conveyor moves and is capable of transporting mines. The elevator conveyor may comprise positioning means just like the conveyors of the storage container. Likewise, the elevator conveyor may comprise guiding means for securing the mines on the elevator conveyor.

[0084] The elevator is constructed such that it can move the elevator conveyor up and down vertically. This may be by using a motor moving the elevator conveyor up and down by mechanical means, e.g. chains or gears. FIG. 3 illustrates a launch container having an elevator 42. The elevator does not need to be part of the launch container. The elevator 42 of the launch container is needed when the storage container comprises mines in multiple layers, thus when the storage container has conveyors in multiple layers.

[0085] The container handling system may further comprise an elevator container. The elevator container frame consists of a top frame and a bottom frame, two side frames and a first end frame 62 and a second end frame 64. All frames are rectangularly shaped such that the container has a rectangular shape. Preferably the elevator container has the same height and width as the storage container and the launch container to be able to connect the containers in a simple way and such that the containers can be packed densely where no space is unused.

[0086] The frame of the elevator container is preferably made in standard sizes of cargo/shipping containers like the ISO 668 standard. Containers following the ISO standard are 2,438 m wide and have different length, where the normal lengths are 6,058 m and 12,116 m but containers can have other lengths as well e.g. shorter than the standard length when combined with a launch container or a storage container. An elevator container may not need to be that long to be able to transport mines up and down. The main heights of the ISO standard are 2,438, 2,591 m and 2,896 m. In other embodiments the container frame sizes are designed for special purposes like specific ships and transport.

[0087] The container frame is usually made of steel but can also be made of different metals or alloys like aluminum. All sides of the containers described may be closed or opened. A closed side could have a wall made of metal, plastic, cloth, or another material for making walls for a container. The ends of the container may be open such that the container is ready to connect to another container and transport mines in or out the ends of the container and there may be doors as mines will be conveyed in and out of the end frames of the containers. The top and the bottom of the containers can be sealed permanently if desired.

[0088] The elevator container comprises an elevator 42, the elevator can move vertically up and down by the use of a motor 14. The elevator 42 is capable of moving to all heights corresponding to the heights of the conveyors 16 in the storage container 8. By being able to move to these heights, mines from all the layers in the storage container 8 can be transported to the transport conveyor 46 of the launch container 40. The elevator 42 may be positioned in the height of a conveyor 16 from the storage container 8 for receiving at least one mine 18. The elevator 42 has an elevator conveyor for receiving and moving mines. Moreover, the elevator may have guiding means for securing the mines on the elevator and to limit the movement of the mines along the length axis of the launch container. After loading one or more mines on the elevator 42 the elevator 42 is moved into the same level as the transport conveyor 46 to connect to the transport conveyor 46 and the mines can be transferred to the transport conveyor 46.

[0089] The elevator container can be connected in both ends of a storage container in order to be able to load mines faster into a launch container 40.

[0090] A container handling system may be comprised of any combination of containers for handling mines e.g. a storage container and a launch container. The containers may be coupled in many different ways due to the shape of the containers. The shape ensures that the end frames of each container are of equal size and that the end frames fit together. This provides a container handling system where mines can be transported by the conveyors from one container to another and thereby be launched from a launch container.

[0091] In an embodiment the container handling system comprises two storage containers and a launch container. The elevator is part of the launch container in this embodiment, alternatively the launch container has no elevator, and an elevator container is added to the container handling system as illustrated in FIG. 4.

[0092] In a preferred embodiment one launch container 40 having an elevator 42 and two storage containers 8 are used. The two storage containers 8 are connected in series such that mines can be transported into the launch container 40. The storage container 8 that transports mines directly onto the elevator 42 in the launch container 40 is called a buffer container 70. As mines are launched from the system, mines are transported from the buffer container 70 and into the launch container 40. The mines are transported from the elevator 42 onto the transport conveyor 46 by the elevator 42 moving to the same height as the transport conveyor 46 allowing the conveyors to be activated by motors 14 and the mines to be transported onto the transport conveyor 46. When the mines are positioned on the transport conveyor 46, an operator 50 or a robot can prepare the mines for launching off the ramp 44. This launching process can be controlled automatically or manually such that there at all times is minimum one mine ready for launching. When mines are used from the buffer container 70, one layer could be used at a time, thus at some point one layer will be completely empty in the buffer container 70. In order to always have mines ready to be launched from the launch container 40, a storage container 8 can be connected to the first end of the buffer container 70. Now mines from the storage container 8 can be conveyed into the buffer container 70 at the empty layer. Thus, the buffer container will always have mines ready to be transferred into the launch container 40 and mines 18 can be launched continuously. This method will empty the storage container 8 transferring mines to the buffer container 70 and the empty storage container 8 can be removed and a new storage container 8 filled with mines can be connected to the buffer container 70 while mines from the buffer container 70 are used. In this way the operator 50 will, as long as there are mines 18 left on the ship, always have mines 18 ready to launch.

[0093] A method for handling mines comprising a first and a second storage container, and a launch container having an elevator, the containers are connected in the following order: the first storage container, the second storage container, and the launch container, the method comprises the following steps: [0094] Transporting a mine from the second storage container into the launch container. This can be done by activating the conveyors of the second storage container and the elevator conveyor of the launch container. The elevator conveyor of the launch container needs to be positioned at the same height as the conveyor supporting the mine to be transported. The container handling system for performing this method is illustrated in FIG. 4. and FIG. 5. [0095] Elevating the mine on the elevator conveyor to the height of the transport conveyor of the launch conveyor. [0096] Transporting the mine to the transport conveyor of the launch container. This is done by activating the elevator conveyor and the transport conveyor. [0097] Inspecting the mine or activating the mine such that the mine is ready for launching. [0098] Launching the mine through the end of the launch container using the launch ramp. This is performed by activating the transport conveyor and the ramp conveyor. [0099] Repeating the above-mentioned steps until a layer of the second storage container is empty. [0100] Transporting mines from the first storage container into the second storage container such that the empty conveyors of the second storage container are refilled with mines. [0101] Repeating the above-mentioned steps until the first storage container is completely empty. [0102] Removing the first storage container and placing a new storage container full of mines instead of the first storage container.

[0103] Part of the steps may be optional e.g. an operator does not need to inspect mines before launching. By using this method, it is ensured that there are always mines for launching as the second storage container also called a buffer container is ensured to have mines ready for transporting to the launch container. When the first storage container is empty, a new one may as described replace the empty one and the steps of the method may be repeated. The buffer container will store mines as long as there are storage containers ready to connect and transfer mines to the buffer container. Thereby the time to replace a storage container connected directly to the launch container does not result in a downtime for launching mines.

[0104] This method may be used for additional mines if e.g. two mines are place in the containers side by side.

[0105] Another method for handling mines comprises the steps of: [0106] Connecting two containers from a group of containers including storage containers and launching containers. The two containers are placed end to end such that mines can be transported directly from one container to the other. [0107] Conveying at least a mine from the first container to the second container. [0108] Optionally launching a mine from the second container.

[0109] The method may be for a container system of a storage container and a launch container connected. Mines can be transported from the storage container to the launch container and launched. The container system may be comprised of more than two containers e.g. 3 containers like two storage containers and one launch container.

[0110] The mine laying system or mine handling system comprising container units is for use on a ship 80. The ship 80 can either be designed to only lay mines, having one or more decks for only mine laying, or having one or more multipurpose decks using container units. These multipurpose decks may be called flex decks. An example of use of a flex deck is illustrated in FIG. 5. The ship may have two openings in the stern of the hull from where mines can be launched. A launch container 40 can be placed in each of the openings of the hull, and a buffer container 70 is connected to the launch container 40. There may be a system for moving storage containers 8 around on the flex deck such that all the mines can be transferred to the launch container 40 and launched.

[0111] The launching system comprising a launch container 40 and at least one storage container 8 can be controlled fully automatically such that mines are launched at a certain frequency or when e.g. a captain decides. Thus, no persons are needed in the process of launching mines using this system, and this enables the ship to launch mines from at least one storage container, and more if the ship has an automatic container movement system.
