Technical Field

The present invention relates to a mobile storage system comprising at least one mobile container having an automated storage and retrieval system for storing and retrieving storage bins.

Background

Mobile containers, such as intermodal or shipping containers, are containers used to store cargo that may be transported by, for example, train, ship, airplane, and truck, and may also be used in these different modes of transportation.

Intermodal containers are used worldwide to efficiently and safely store and transport cargo around the world. They are often referred to by different names, such as freight containers, ISO containers and shipping containers.

Intermodal containers come in many different standard sizes and are typically made of steel or aluminum. The dimensions of the intermodal containers may vary from 2.4m to 17.1m in length, from 2.2m to 2.5m in width, and from 2.2m to 2.9m in height.

Table 1 shows an example of the most common standardized type of intermodal container sizes and payload.

Table 1: size and payload of intermodal containers.

Intermodal containers can bundle goods and cargo into large, uniform loads that can be easily handled, moved, and stacked, and tightly packed on a ship or in a yard. Intermodal containers have many structural features that withstand the pressure of intermodal shipments, facilitate their handling, and allow stacking. Furthermore, these intermodal containers may be identified by independent unique ISO 6346 reporting markers.

Automated storage and retrieval systems, including grid storage systems, are known in the art.

Fig. 1 discloses a typical prior art automated storage and retrieval system 1 having a frame structure 100, and fig. 2 and 3 disclose two different prior art container handling vehicles 201,301 suitable for operation on such a system 1.

The frame structure 100 comprises a plurality of upright/vertical members 102 and a plurality of horizontal members 103, which may be supported by the vertical members 102 and/or arranged at the base of the frame structure 100 (not shown). When the horizontal members 103 are arranged at the base of the frame structure 100, they may be arranged in a grid pattern supporting the vertical members 102. The members 102, 103 may typically be made of metal, such as extruded aluminum profiles.

The frame structure 100 defines a storage grid structure 104 that includes storage columns 105 arranged in rows. In these storage columns 105, storage bins 106 (also referred to as storage containers) are stacked one on top of the other to form a stack 107. The storage grid structure 104 prevents horizontal movement of the stack 107 of storage bins 106 and guides vertical movement of the bins 106, but generally does not support the storage bins 106 as they are stacked.

The automated storage and retrieval system 1 includes a rail system 108 arranged in a grid pattern across the top of the storage grid structure 104, on which rail system 108 a plurality of bin handling carts 201,301 operate to raise and lower the storage bins 106 from and into the storage columns 105, and also transport the storage bins 106 over the storage columns 105. The rail system 108 includes: a first set of parallel guide rails 110 arranged to guide the movement of the box-loading and unloading vehicles 201,301 in a first direction X across the top of the frame structure 100; a second set of parallel guide rails 111 arranged perpendicular to the first set of guide rails 110 to guide the movement of the box-loading and unloading vehicles 201,301 in a second direction Y perpendicular to the first direction X. In this way, the rail system 108 defines a grid column 112 on which the box-handling carts 201,301 can be moved laterally over the storage column 105, i.e. in a plane parallel to the horizontal X-Y plane.

Each prior art cassette handler 201,301 includes a body 201a, 301a and a first set of wheels 201b, 301b and a second set of wheels 201c, 301c that enable the cassette handler 201,301 to move laterally in the X and Y directions, respectively. In fig. 2 and 3, the two wheels of each set are fully visible. The first set of wheels 201b, 301b is arranged to engage with two adjacent rails of the first set of rails 110 and the second set of wheels 201c, 301c is arranged to engage with two adjacent rails of the second set of rails 11. Each set of wheels 201b, 301b, 201c, 301c may be raised and lowered such that the first set of wheels 201b, 301b and/or the second set of wheels 201c, 301c may engage the respective set of rails 110, 111 at any time.

Each prior art bin truck 201,301 also includes lifting means (not shown) for vertical transport of the storage bin 106, such as lifting the storage bin 106 from the storage column 105 and lowering the storage bin into the storage column. The lifting device includes one or more gripping/engaging devices 303 adapted to engage the storage bin 106. The gripping/engaging means 303 may be lowered from the carts 201,301 such that the position of the gripping/engaging means 303 relative to the carts 201,301 may be adjusted in a third direction Z orthogonal to the first direction X and the second direction Y. Further details regarding the lifting device are described, for example, in WO2017/211634a1, which is incorporated herein by reference.

Conventionally, and also for purposes of this application, Z ═ 1 identifies the uppermost tier of the storage grid structure 104, i.e., the tier immediately below the rail system 108; z2, which is the second layer below the rail system 108; z3, which is the third tier below the rail system 108. In the exemplary prior art storage grid structure disclosed in fig. 1, Z-8 identifies the lowest floor of the storage grid structure 104. Similarly, X1.. n and Y1.. n identify the position of each grid column 112 in the horizontal plane. Thus, by way of example, and using the cartesian coordinate system X, Y, Z shown in fig. 1, it can be said that the bin identified as 106' in fig. 1 occupies a grid position or cell X-0, Y-2, and Z-3. It can be said that the truck 201,301 travels in layers Z-0 and each grid column 112 can be identified by its X and Y coordinates.

Each prior art bin loader/unloader 201,301 includes a storage compartment or space for receiving and loading the storage bin 106 as the storage bin 106 is transported across the rail system 108. The storage space may comprise a cavity centrally disposed within the vehicle body 20la, as shown in fig. 2 and as described in, for example, WO 2015/193278 a1 and WO 2018/033426 a1, which are incorporated herein by reference.

Fig. 3 shows an alternative configuration of a container handling vehicle 301 having a cantilever structure. Such carts are described in detail in, for example, N0317366, the contents of which are also incorporated herein by reference.

The central cavity bin loader 201 shown in fig. 2 may have a footprint that covers an area having dimensions in the X-direction and Y-direction that is generally equal to the lateral extent of the grid posts 112, i.e., the extent of the grid posts 112 in the X-direction and Y-direction, for example as described in WO 2015/193278 a1, the contents of which are incorporated herein by reference. The term "lateral" as used herein may mean "horizontal".

Alternatively, the central cavity bin truck 201 may have a footprint larger than the lateral area defined by the grid posts 112, for example, as disclosed in WO 2014/090684 a 1.

The rail system 108 may be a single rail system as shown in fig. 4. Alternatively, the rail system 108 may be a dual rail system as shown in fig. 5, allowing a tote cart 201 having a footprint generally corresponding to the lateral area defined by the grid columns 112 to travel along a row of grid columns even if another tote cart 201 is positioned above a grid column adjacent to the row. The single rail system and the double rail system, or a combination of single rail and double rail arrangements in the single rail system 108, each form a grid pattern comprising a plurality of rectangular and uniform grid positions or grid cells 122 in the horizontal plane P, wherein each grid cell 122 comprises a grid opening 115 defined by a pair of rails 110a, 110b in the first set of rails 110 and a pair of rails 11la, 11lb in the second set of rails 111. In fig. 5, the grid cells 122 are indicated by dashed boxes.

Thus, the guide rails 110a and 110b form a pair of guide rails defining parallel rows of grid cells extending in the X direction, and the guide rails 11la and 11lb form a pair of guide rails defining parallel rows of grid cells extending in the Y direction.

As shown in FIG. 6, each grid cell 122 has a width W that is typically within the interval of 30cm to 150cm_cAnd a length Lc typically in the interval 50cm to 200 cm. Width W of each grid opening 115_oTypically 2cm to 10cm less than the width Wc of the grid cells 122. The length L of each grid opening 115_oTypically 2cm to 10cm less than the length Lc of the grid cell 122.

In the X-direction and the Y-direction, adjacent mesh cells are arranged in contact with each other such that there is no space between the adjacent mesh cells.

In the storage grid structure 104, most of the grid columns 112 are storage columns 105, i.e. the grid columns 105 of the storage bins 106 are stored in a stack 107. However, the storage grid structure 104 typically has at least one grid post 112 that is not used to store the storage bin 106, but rather includes a location where the bin loader vehicle 201,301 may unload and/or pick up the storage bin 106 so that the storage bin may be transported to an access station (not shown) where the storage bin 106 may be accessed from outside the storage grid structure 104, or the storage bin 106 may be transferred out of or into the storage grid structure 104. Such locations are commonly referred to in the art as "ports" and the grid posts 112 where the ports are located may be referred to as "port posts" 119, 120. The transport to the access station can be done in any direction, i.e. horizontal, inclined and/or vertical. For example, the storage bins 106 may be placed in random or dedicated grid columns 112 within the storage grid structure 104 and then picked up by any bin dumper and transported to ports 119, 120 for further transport to an access station. Note that the term "tilt" refers to the transport of the bin 106 with a general transport orientation between horizontal and vertical.

The storage grid structure 104 in fig. 1 includes two harbor columns 119 and 120. The first port column 119 may, for example, be a dedicated discharge port column in which the bin dumper 201,301 may discharge the storage bin 106 for transport to the access station or the transfer station, and the second port column 120 may be a dedicated pick-up port column in which the bin dumper 201,301 may pick up a storage bin 106 that has been transported from the access station or the transfer station to the storage grid structure 104.

The access station may generally be a pick-up station or an inventory station that removes product items from the storage bin 106 or places them into the storage bin 106. In the pick-up station or inventory station, the storage bins 106 are not typically removed from the automated storage and retrieval system 1, but are returned to the storage grid structure 104 once accessed. The ports 119, 120 may also be used to transfer storage bins out of or into the grid 104, for example, to transfer storage bins 106 to another storage facility (e.g., to another grid or another automated storage and retrieval system), a transport vehicle (e.g., a train or truck), or a production facility.

A conveyor system including a conveyor is typically employed to transport the storage boxes between the ports 119, 120 and the access station.

If the ports 119, 120 and the access station are located at different heights, the conveyor system may include a lifting device having a vertical assembly for transporting the storage boxes 106 vertically between the ports 119, 120 and the access station.

The conveyor system may be arranged to transfer the storage bins 106 between different grids, for example as described in WO 2014/075937 a1, which is incorporated herein by reference.

When a storage bin 106 stored in the grid 104 disclosed in fig. 1 is to be accessed, one of the bin loading and unloading vehicles 201,301 is instructed to retrieve the target storage bin 106 from its position in the storage grid structure 104 and transport it to the unloading port 119. This operation involves moving the bin loader/unloader 201,301 to a grid position above the storage column 105 where the target storage bin 106 is located, retrieving the storage bin 106 from the storage column 105 using a lifting device (not shown) of the bin loader/unloader 201,301, and transporting the storage bin 106 to the unloading port 119. If the target storage bin 106 is located deep within the stack 107, i.e., one or more other storage bins 106 are located above the target storage bin 106, the operation also involves temporarily moving the above-located storage bin before lifting the target storage bin 106 from the storage pole 105. This step, sometimes referred to in the art as "digging," may be performed using the same bin loader 201,301 that is subsequently used to transport the target storage bin 106 to the unloading port 119, or using one or more other cooperating bin loaders 201, 301. Alternatively or additionally, the automated storage and retrieval system 1 may have a bin load and unload vehicle 201,301 dedicated to the task of temporarily removing the storage bin 106 from the storage column 105. Once the storage bin 106 has been removed from the storage column 105, the temporarily removed storage bin 106 may be repositioned into the original storage column 105. However, the removed storage bin 106 may alternatively be relocated to other storage columns 105.

When the storage bins 106 are stored in the storage grid structure 104, one of the bin loaders 201,301 is instructed to pick up the storage bin 106 from the pick-up port 120 and transport it to a grid location above the storage column 105 where it is to be stored. After any storage bin located at or above the target location within the storage column stack 107 has been removed, the bin unloader 201,301 positions the storage bin 106 at the desired location. The removed storage bin 106 may then be lowered back into the storage column 105 or replaced into another storage column 105.

The automated storage and retrieval system 1 includes a control system for monitoring and controlling the automated storage and retrieval system 1, for example, for monitoring and controlling the position of the respective storage bins 106 within the storage grid structure 104, monitoring the contents of each storage bin 106, and monitoring and controlling the movement of the bin loaders 201,301, such that a desired storage bin 106 may be delivered to a desired location at a desired time without the bin loaders 201,301 colliding with each other. The control system is typically computerized and typically includes a database for keeping track of the storage bins 106.

The automated storage and retrieval system 1 may include a tote cart, one or more charging stations for charging the tote cart, and a wireless communication system. Such features are also known from WO 2015/104263 a1, which is incorporated herein by reference.

The invention is set forth and characterized in the independent claims, while the dependent claims describe preferred or optional features of the invention.

The mobile storage system may include a plurality of mobile containers, each having an automated storage and retrieval system for storing storage bins (where the bins may contain items). One of the mobile containers may be a so-called master container having a storage column and a dedicated column for receiving storage bins from and delivering storage bins to an access station. The remaining mobile containers may be so-called supply containers which include automated storage and retrieval systems without dedicated posts for receiving and delivering storage bins from and to the access station. Within the system, the main container may be connected to at least one supply container such that the container handling vehicle may be moved from the storage grid structure of the main container to the storage grid structure of the supply container. Furthermore, the main container and/or the supply container may be connected to a plurality of supply containers, which in turn may be connected to a plurality of supply containers, etc. Thus, the mobile storage system can be sized as desired. Furthermore, the mobile storage system may provide a flexible system in which a mobile container arranged at any end of a side-by-side mobile container arrangement may be replaced with another mobile container.

The frame structure of an automated storage and retrieval system according to embodiments of the present invention may be constructed according to the prior art frame structure described above in connection with fig. 1-6, i.e. such a frame structure may comprise a plurality of vertical members and a plurality of horizontal members. As in the prior art, automated storage and retrieval systems may include a rail system that includes a first set of parallel rails in the X-direction and a second set of parallel rails in the Y-direction that traverse the tops of the storage columns defined by the frame structure/grid columns defined by the two sets of rails.

A first embodiment of the present invention is directed to a mobile storage system including a first mobile container having a first automated storage and retrieval system disposed within an interior. The first automated storage and retrieval system includes a first storage grid structure having vertical members that define a plurality of columns, such as storage columns for storing storage bins in vertical stacks stacked on top of one another. The vertical members are interconnected at their upper ends by a first rail system arranged to guide at least one container handling vehicle thereon. The bin unloader is configured to raise the storage bin from the storage pole and lower the storage bin into the storage pole and transport the storage bin over the storage pole.

The first mobile container may further comprise a first container frame having a base panel, a top panel and four vertically extending profiles extending from each corner of the base panel to connect the base panel and the top panel.

The first mobile container may comprise two long end side panels and two short end side panels. At least a portion of at least one side panel may be removable.

The side panels may be fixed (e.g., removably fixed) to the vertically extending profiles (i.e., each side panel may be connected to two vertically extending profiles). The side panels may also be secured (e.g., removably secured) to the top and bottom panels.

In embodiments where the first mobile container is a stand-alone unit (i.e. not connected to any other mobile container), the removable portion of at least one side panel may form a doorway or similar opening for a person to access the first mobile container.

In embodiments where the first mobile container is to be connected with another mobile container, to connect two or more automated storage and retrieval systems together, the removable portion of the at least one side panel may form an access opening for allowing connection between the first automated storage and retrieval system in the first mobile container and the second automated storage and retrieval system in the second mobile container.

In particular, when removing at least a portion of the side panel, it may form an opening, the size of which should be at least the size of the largest cross section (taken in a vertical plane perpendicular to the axis of movement of the box-loading wagon when moving through the opening, said vertical plane being parallel to the plane of the panel in which the opening is formed) of the box-loading wagon carrying the box moving on the rail system.

Furthermore, the openings should of course be positioned accordingly, i.e. so that the container handling vehicle can be moved from the rail system of one moving container to the rail system of another moving container. That is, the opening may have a vertical extent extending at least from directly below the horizontal plane of the rail system, at least up to the height of the box loading and unloading vehicle carrying the box on the rail. The opening may extend vertically below such opening and/or vertically above such opening.

Of course, the opening may be larger than the size of the largest cross-section of the box-loading wagon of the carrying box moving on the rail system. For example, the height of the opening may be at least the height of a box-handling vehicle carrying the containers moving on the rail system, but the width may extend across substantially the entire side to which two containers are to be connected. The opening may be formed by removing the panel, in which case the size of the opening is of course substantially the size of the removed panel.

The first mobile container may comprise at least two openings; a first opening allowing personnel to enter a first mobile container (e.g., a doorway); and a second opening allowing a connection between the first automated storage and retrieval system in the first mobile container and the second automated storage and retrieval system in the second mobile container (and in particular allowing a container handling vehicle carrying a container to move from the guide rail of the first automated storage and retrieval system in the first mobile container onto the guide rail of the second automated storage and retrieval system in the second mobile container). The first mobile container may comprise an opening on one, two, three or four of its four side panels.

When connecting two moving containers in a side-by-side arrangement along the long end side, at least a portion of the long end side panel is removable for forming an opening. In another exemplary embodiment, the entire long end side panel may be removed. It is advantageous to allow the rail systems of two mobile containers to be connected after the two mobile containers have been connected. A rail system may be attached to allow the case handling vehicle to move from one storage and retrieval system to another.

When two moving containers are connected in a side-by-side arrangement along their short end sides, at least a portion of their respective short end side panels (at the short end sides connecting the two moving containers) are removable for forming an opening.

In another exemplary embodiment, the entire short end side panel (at the short end side where the two moving containers are connected) may be removed.

In a further exemplary embodiment, both the short end side panel and the long end side panel comprise at least a portion that is removable for forming an opening that should be at least the size of the largest cross-section of the box-loading wagon of the carrying box that is moved thereon. Furthermore, these openings should of course be positioned accordingly, i.e. so that the container handling vehicle can be moved from the rail system of one moving container to the rail system of another moving container.

In order to enable access to the storage bins from outside the first storage grid structure, at least one of the posts in the first storage and retrieval system may be dedicated to unloading and/or picking up the storage bin by a bin loader truck. Furthermore, at least one access station may be arranged adjacent to the at least one dedicated post, where an operator may access to remove articles from the storage box and/or access to supply articles to the storage box. At the access station, the storage bin may be accessed from outside the first storage grid structure, or the storage bin may be transferred out of or into at least one column of the first storage grid structure dedicated to unloading and/or picking up the storage bin.

The dedicated pillars may be an integral part of the first storage grid structure.

If more containers are connected to the master container, the first mobile container with a storage bin accessible to the operator may be considered the master container.

The first automated storage and retrieval system of the first mobile container may further comprise at least one charging station for charging the container handling vehicle, said charging station being arranged at or on the rail system. The number of charging stations may be adjusted according to the number of vehicles operating within the system.

Further, the first automated storage and retrieval system may have a controller for storing, receiving and/or transmitting data regarding the items stored in the storage bins and the locations of the storage bins. In this way, the system may be monitored as to where each stored item and/or bin is and how many items in each item are stored in the system.

In another embodiment of the invention, the first mobile container may have height adjustable feet secured to an outer lower surface of the first mobile container, allowing for height adjustment and/or leveling of the first mobile container. As will be explained in detail in the detailed description, leveling is particularly important when two moving containers are connected together in order to connect two or more automated storage and retrieval systems together, since the rail systems connected together from each moving container should be connected together with high accuracy and precision.

The mobile storage system may further include a second mobile container configured to be removably connected to the first mobile container. A second automated storage and retrieval system is disposed within the second mobile container. The second automated storage and retrieval system includes a second storage grid structure having vertical members defining a plurality of storage columns for storing storage bins in a stack one on top of the other. The vertical members are interconnected at their upper ends by a second rail system arranged to guide at least one box-loading wagon thereon. The bin unloader is configured to raise the storage bin from the storage pole and lower the storage bin into the storage pole and transport the storage bin over the storage pole.

The second mobile container may further comprise a second container frame having a base panel, a top panel and four vertically extending profiles extending from each corner of the base panel to connect the base panel and the top panel.

At least one of the base panel, the top panel and the vertically extending profiles of the first and second moving containers may have a rectangular parallelepiped shape, wherein holes are provided for receiving the connecting elements when connecting the two moving containers together.

The second container frame may further comprise two long end side panels and two short end side panels, wherein at least a portion of one of the side panels is removable (to form an opening into the second container).

The side panels may be fixed (e.g., removably fixed) to the vertically extending profiles (i.e., each side panel may be connected to two vertically extending profiles). The side panels may also be secured (e.g., removably secured) to the top and bottom panels.

In general, the second container may be referred to as a "supply container". The supply container differs from the master container in that the supply container does not comprise a dedicated post for receiving the storage bin from the access station and delivering the storage bin to the access station, whereas such a dedicated post for receiving the storage bin from the access station and delivering the storage bin to the access station is present in the master container.

No personnel are required to enter the supply container since the supply container does not have a dedicated post for receiving and delivering storage bins from and to the access station. Thus, in some embodiments, the second container may include an opening for connection only to another moving container. The opening may be for connection to a main container or to another supply container.

Thus, when a mobile container is to be connected with a first (primary) mobile container (or another second (supply) mobile container), at least a portion of at least one side panel may be removable (as described above) in order to connect two or more automated storage and retrieval systems together. When at least a portion of the side panel is removed, it may form an opening, the size of which may be at least the size of the largest cross-section (taken in a vertical plane perpendicular to the axis of movement of the box-loading wagon when moving through the opening, said vertical plane being parallel to the plane of the panel in which the opening is formed) of the box-loading wagon carrying the box moving on the rail system.

Furthermore, the opening should of course be positioned accordingly, i.e. so that the container handling vehicle can be moved from the rail system of the first moving container onto the rail system of the second moving container. That is, the opening may have a vertical extent extending at least from directly below the horizontal plane of the rail system, at least up to the height of the box loading and unloading vehicle carrying the box on the rail. The opening may extend vertically below such opening and/or vertically above such opening

Of course, the size of the opening may be larger than the size of the largest cross-section of the box-loading wagon of the carrying box moving on the rail system. For example, the height of the opening may be at least the height of a box-handling vehicle of a carrying box moving on the rail system, but the width may extend across substantially the entire side to which two containers are to be connected. The opening may be formed by removing the panel, in which case the size of the opening is of course substantially the size of the removed panel.

If two mobile containers are connected in a side-by-side arrangement along the long end side, at least a portion of the long end side panels are removable to form an opening. In another exemplary embodiment, the entire long end side panel is removable. In other embodiments, at least a portion of the short end side panels are removable to form the opening. In another embodiment, the entire short end side panel is removable.

It should be understood that one, two, three or all four side panels of the second moving container may include an opening sized and positioned to allow the container handling vehicle to move from the rail system of the second moving container to another rail system of the connecting container. How many sides comprise openings will depend on how many other moving containers the second moving container is connected to.

Furthermore, the second mobile container may comprise a controller for storing, receiving and/or transmitting data regarding the items stored in the storage bin of the second mobile container and the location of the storage bin.

The controller of the second mobile container may communicate with another controller, for example, the master controller of the first (master) mobile container.

To facilitate a high precision alignment of the grid structure within the first mobile container with the grid structure of the connected second mobile container, the first storage grid structure of the first mobile container and/or the second storage grid structure of the second mobile container may be arranged on a horizontally displaceable base plate (within the respective mobile container) configured to allow a horizontal displacement of the plate itself to result in a displacement of the storage grid structure placed thereon.

Furthermore, the second mobile container may comprise height adjustable feet fixed to the outer lower surface, allowing height adjustment and/or leveling of the second mobile container.

When connecting two mobile containers together, the part of the frame of each mobile container that faces the other mobile container when connected may be connected by coupling means. In one embodiment, the portion of the first container frame and the portion of the second container frame that face each other when connected comprise coupling means allowing the first container frame and the second container frame to be aligned.

In one exemplary embodiment, the vertical extent of at least one of the base panel, the top panel and/or the one vertically extending profile of the first moving container may comprise at least one hole facing at least one corresponding hole arranged in the vertical extent of at least one of the base panel, the top panel and/or the one vertically extending profile of the second moving container for inserting a connecting pin between the first moving container and the second moving container for aligning the two containers in at least one of a vertical position and a horizontal position.

In a preferred embodiment, the first mobile container comprises at least two holes arranged within the vertical extent of the base panel, which at least two holes face at least two corresponding holes arranged on the vertical extent of the base panel of the second mobile container.

In a more preferred embodiment, the first mobile container comprises at least four holes arranged in the vertical extent of the base panel, facing at least four corresponding holes arranged in the vertical extent of the base panel of the second mobile container.

In a preferred embodiment, the holes are evenly distributed along the vertical extent and/or one of the vertically extending profiles. Instead of connecting the moving containers with pins located in holes, ball and socket type coupling devices, or other known coupling devices that ensure a tight fit alignment between the connected moving containers, may also be used.

The holes may have a funnel shape and the pins may be configured to match at least the smallest diameter of the funnel-shaped holes, thereby forming a tight fit. An example of a "funnel-shaped" hole is a smooth tapered hole that narrows from a maximum cross-section at the entrance of the hole to a minimum cross-section at the other end of the hole inside the frame (i.e. inside the base panel, the top panel or the vertically extending profile). The bore may have a circular cross-section along its length. Thus, a "funnel-shaped" bore may be a conical (or frustoconical) bore. Alternatively, a "funnel-shaped" bore may comprise a wide cylindrical outer portion (closest to the entrance of the bore) and a frustoconical inner portion (furthest from the entrance of the bore). The cross-section of the bore is then initially constant for the outer portion before narrowing along the inner portion.

The connecting pin may be telescopic such that the connecting pin in the retracted state occupies a hole in the first moving container frame or a hole in the second moving container frame.

In order to connect the first rail system of the first moving container to the second rail system of the second moving container, an intermediate element may be used to allow the storage van to move between the first rail system and the second rail system.

In another embodiment of the mobile storage system, the mobile container may be arranged on top of another mobile container. In an exemplary embodiment, the second mobile container (supply container) may be arranged on top of the first mobile container (main container). In such a configuration, the base panel of the second mobile container will have an opening corresponding to the opening in the top panel of the first mobile container. The opening is formed to allow the storage bin to move between the first moving container and the second moving container.

It should be understood that the mobile storage system may include a plurality of mobile containers stacked vertically.

Two vertically stacked mobile containers may be engaged by an interlock, such as the one shown in US 5346084 a. However, any type of interlocking device may be used to maintain the containers in vertical alignment.

In another embodiment, the mobile container system comprises a plurality of second mobile containers (supply containers) aligned adjacent to each other, e.g. in a side-by-side arrangement.

In a further embodiment, one second moving container (supply container) may be arranged on top of another second moving container (supply container). The two second moving containers may have corresponding openings to allow the storage bin to move between the two second moving containers.

Furthermore, the mobile container system may comprise a plurality of mobile containers arranged in a first row of the side-by-side arranged mobile containers, wherein a second row of the side-by-side arranged mobile containers is arranged on top of the first row. The system may comprise a plurality of such vertically stacked rows of mobile containers.

In further embodiments, the mobile container system may comprise at least one equipment container for storing equipment, such as air conditioning systems, generators, fire suppression systems, and the like. The equipment container may be connected to the first mobile container or the second mobile container, i.e. to the master container or the supply container.

As described above, two mobile containers may be connected and aligned to provide precise alignment of the two rail systems of the two automated storage and retrieval systems disposed within the two mobile containers. If height adjustable feet are provided, the height adjustable feet may align the mobile containers in the same horizontal position (level), thereby aligning the automated storage and retrieval system in the vertical Z-direction. If a base panel is provided, the base panel may adjust the alignment of the two storage and retrieval systems in the horizontal Y-direction and/or the horizontal X-direction, and the intermediate element may connect the rails of the two storage and retrieval systems in the X-direction.

Furthermore, the coupling means preferably provide a close fitting alignment between the connected mobile containers.

The invention also relates to a method of providing a mobile storage system, the method having the steps of:

-providing a first mobile container;

-arranging a first automated storage and retrieval system inside a first mobile container; and

-transporting a first mobile container having a first automated storage and retrieval system therein to a location of use.

The method may further comprise the steps of:

-providing a second mobile container;

-arranging a second automated storage and retrieval system inside a second mobile container; and

-transporting a second mobile container having a second automated storage and retrieval system therein to a location of use; and

-connecting the first mobile container and the second mobile container together.

In an embodiment, wherein the first mobile container comprises a first container frame having: a base panel, a top panel, four vertically extending profiles extending from each corner of the base panel to connect the base panel and the top panel, two long end side panels, and two short end side panels, wherein at least a portion of one of the side panels is removable, and wherein the second mobile container comprises a second container frame having: a base panel, a top panel, four vertically extending profiles extending from each corner of the base panel to connect the base panel and the top panel, and two long end side panels and two short end side panels, wherein at least a portion of one of the side panels is removable, the method comprising:

a) removing at least a portion of one of the side panels of the first container frame, thereby forming an opening having a size of at least the size of the cross-section of the box-handling vehicle of the carrier box moving on the rail system,

b) removing at least a portion of one of the side panels of the second container frame, thereby forming an opening having a size of at least the size of the cross-section of the box-handling vehicle of the carrier box moving on the rail system,

c) the opening of the first container frame is arranged corresponding to the opening of the second container frame, an

d) The first rail system and the second rail system are connected by arranging an intermediate element between the first rail system and the second rail system.

Furthermore, step c) may further comprise connecting the first container frame with the second container frame by means of a coupling device, thereby allowing the first container frame and the second container frame to be aligned.

The method may further comprise using the height adjustable feet to adjust the height and/or horizontal position of the first or second moving container relative to the height of the other moving container.

In one embodiment of the mobile container system, the mobile containers have the size and shape of 20 ', 40 ' and/or 45 ' intermodal containers.

Detailed Description

Hereinafter, embodiments of the present invention will be discussed in more detail with reference to the accompanying drawings. It should be understood, however, that the drawings are not intended to limit the invention to the subject matter depicted in the drawings.

The frame of the automated storage and retrieval system according to the present invention may be constructed according to the prior art frame described above in connection with fig. 1 to 6, i.e. it may comprise a plurality of upright/vertical members and preferably a plurality of horizontal members, furthermore the frame may comprise a rail system of parallel rails in the X-direction and the Y-direction arranged across the top of the storage/grid columns.

The prior art grid shown in fig. 1 has a height of eight cells. It should be understood, however, that the grid may in principle have any height that fits inside a moving container. Similarly, the prior art grid shown in fig. 1 has 11 cells in the X-direction and 13 cells in the Y-direction. It should be understood, however, that the grid may in principle have any size that fits inside a moving container. Furthermore, the mobile container may be of any suitable size.

The mobile storage system and mobile container with automated storage and retrieval system will now be discussed in more detail.

The mobile container with automated storage and retrieval system may be transported by aircraft, truck, train, etc. to any desired location. During transport, the container frame comprises a base panel, a top panel, four vertically extending profiles and four side panels attached at their vertical edges to the vertically extending profiles, wherein the first side panel preferably comprises a door to access an automated storage and retrieval system inside the moving container. When the mobile container is placed in its desired position, it may be ready for operation. However, if the mobile container is to be interconnected with one or more mobile containers such that the container handling vehicle moves between the interconnected mobile containers, it is necessary to remove at least a portion of one of the side walls of the mobile container.

Fig. 7 illustrates an exemplary embodiment of a mobile storage system having a first mobile container 600 of the first automated storage and retrieval system 500.

The first mobile container 600 has a base panel/floor 601 and a top panel/roof 602. The top panel 602 is arranged directly above the base panel 601 and they are separated by four vertically extending profiles 606 (such as uprights) which extend from the corners of the base panel 601 to the corresponding corners of the top panel. Four side panels 603, 604 may be attached at their vertical edges to adjacent vertically extending profiles 606 to form walls of the container frame 600'. In fig. 7, a first short end side panel 604 is attached at its vertical edge to two adjacent vertically extending profiles 606. Between two other vertically extending profiles 606 is a door 605 which when closed serves as the second short end side panel 604. In fig. 7, the first long end side panel has been physically removed, while the second long end side panel cannot be seen for illustration purposes.

The first automated storage and retrieval system 500 is disposed within the container frame 600' of the first mobile container 600 on top of the base panel 601. The first automated storage and retrieval system 500 has a grid structure 504 with vertical members 502 defining a plurality of storage columns. The vertical members 502 are interconnected at their upper ends by a rail system 508 arranged in a grid pattern across the top of the first storage grid structure 504. On this rail system 508, the plurality of bin loaders 201,301 operate to raise and lower storage bins (not shown) from and into the storage posts 505, and also transport the storage bins over the storage posts 505. The rail system 508 includes: a first set of parallel rails arranged to guide the movement of the bin loaders 201,301 in a first direction X across the rail system 508; a second set of parallel guide rails arranged perpendicular to the first set of guide rails to guide the movement of the bin loaders 201,301 in a second direction Y perpendicular to the first direction X. In this way, the rail system 508 defines a grid/storage column 505 over which the case handling cart 201,301 can be moved laterally over the storage column 505, i.e. in a plane parallel to the horizontal X-Y plane.

Each of the truck-loaders 201,301 includes a body/chassis and first and second sets of wheels that enable the truck-loaders 201,301 to move laterally in the X and Y directions, respectively. Referring to fig. 2 and 3, the two wheels in each set are fully visible. The first set of wheels 201b, 301b is arranged to engage with two adjacent rails of the first set of rails and the second set of wheels 201c, 301c is arranged to engage with two adjacent rails of the second set of rails. Each set of wheels 201b, 301 b; 201c, 301c may be raised and lowered such that the first set of wheels 201b, 301b and/or the second set of wheels 201c, 301c may engage the respective set of rails at any time.

In order to enable access to the storage bins from outside the storage grid structure 504, four posts 512 are shown which are dedicated to unloading and/or picking up the storage bins by the bin loaders 201, 301. With respect to two of the four posts 512, two adjacent access stations 509 are shown, wherein an operator may access to remove items from the storage bin and/or access to supply items into the storage bin. Such a first mobile container 600 comprising a first storage grid structure 504 accessible by an operator may be referred to as a master container. The door 605 allows an operator to access the interior of the main container 600.

The master container may include one or more charging stations 550 for charging the container handling vehicles. The charging station is preferably arranged at or on the rail system 508. In fig. 7, a charging station 550 is arranged at the periphery of the rail system 508 to allow the container handling vehicles 201,301 to enter the charging station 550. Such a charging station is known from WO 2015/104263 a 2.

The master container may include a controller/control unit (not shown) for storing, receiving and/or transmitting data regarding items stored in the storage bins, and for storing, receiving and/or transmitting data regarding the location of each storage bin. The controller may also communicate with the container handling vehicle 201,301 via, for example, a wireless link so that the container handling vehicle 201,301 may be charged at a charging station 550 when needed (typically at night).

The master container may also include a master controller/control system for storing, receiving and/or transmitting data from other controllers within the system. The master controller may also store, receive, and/or transmit data related to items removed or added by an operator at the access station.

As mentioned above, the mobile storage system may consist of only one main container, wherein the container frame comprises a base panel, a top panel and four vertically extending profiles forming the edges of four side walls, wherein one of the side walls comprises a door for an operator to access an access station of the automated storage and retrieval system inside the main container.

The first container frame 600' of the first mobile container 600 shown in fig. 7 may be a prior art intermodal container as described above. It may be a 20 ' container, a 40 ' container or a 45 ' container as described above. If the first mobile container 600 is to be interconnected with another mobile container, at least a portion of one of the side walls of the first mobile container 600 needs to be removed in order for the container handling vehicle to move between the interconnected mobile containers.

Fig. 8 shows a mobile storage system with a second mobile container 700 having a second automated storage and retrieval system 500'.

The second mobile container 700 has a base panel/floor 701 and a top panel/roof 702. The top panel 702 is arranged directly above the base panel 701 and they are separated by four vertically extending profiles 706 which extend from the corners of the base panel 701 to the corresponding corners of the top panel 702. Four side panels may be attached at their vertical edges between adjacent vertically extending profiles 706. In fig. 7, two adjacent vertically extending profiles 706 form the edge of the short end side panel 704 and two other vertically extending profiles 706 form the edge of a door 705 which when closed acts as the short end side panel 704. In fig. 7, the long end side panel has been physically removed for attaching the second mobile container with two other mobile containers, one on each side. The mobile container may be a first mobile container or a second mobile container, see fig. 9-12.

During transport of the second mobile container 700, two long end side panels (not shown) will be attached to the second container frame 700 'enclosing the automated storage and retrieval system 500' disposed inside the second mobile container. When the second mobile container 700 arrives at the appropriate location, the second mobile container 700 will be connected to at least one other mobile container including an automated storage and retrieval system. At least one of the long end side walls will be at least partially removed prior to or during connection for allowing the container handling vehicle(s) 201,301 to move between two moving containers, each including an automated storage and retrieval system. The connected mobile container(s) will then have corresponding opening(s) in its long end side wall(s).

Fig. 7 shows a second automated storage and retrieval system 500 'disposed inside a second container frame 700' of a second mobile container 700. The second automated storage and retrieval system 500 ' has a rail system 508' arranged in a grid pattern across the top of the second storage grid structure 504 '. The second storage grid structure 504 ' has a plurality of vertical members 502' defining a plurality of storage columns 505 ', and the vertical members 502' are interconnected at their upper ends by a rail system 508 '. On this rail system 508', a plurality of bin unloader cars (not shown) may be operated to raise and lower the storage bins 106 from and into the storage posts 505 ', and also transport the storage bins 106 over the storage posts 505 '. The rail system 508' includes: a first set of parallel guide rails arranged to guide movement of the bin loaders across the top of the second storage grid structure 504' in a first direction X; and a second set of parallel guide rails arranged perpendicular to the first set of guide rails to guide movement of the box-loading wagon in a second direction Y perpendicular to the first direction X. In this manner, the rail system 508' defines a grid/storage column 505 ' above which the case handling cart may be moved horizontally over the storage column 505 ', i.e., in a plane parallel to the horizontal X-Y plane.

Each of the truck units includes a body and first and second sets of wheels that enable the truck units to move laterally in the X and Y directions, respectively. Referring to fig. 2 and 3, the two wheels in each set are fully visible. The first set of wheels 201b, 301b is arranged to engage with two adjacent rails of the first set of rails and the second set of wheels 201c, 301c is arranged to engage with two adjacent rails of the second set of rails. Each set of wheels 201b, 301 b; 201c, 301c may be raised and lowered such that the first set of wheels 201b, 301b and/or the second set of wheels 201c, 301c may engage the respective set of rails at any time.

The second mobile container 700 may be referred to as a supply container because it may supply the main container with storage bins that may be delivered to its access port, as will be described in further detail in fig. 9-12.

The second mobile container 700 may comprise one or more charging stations for charging the container handling vehicles 201, 301. The charging station(s) are preferably arranged at or on the rail system 508'.

The second mobile container 700 may include a controller for storing, receiving and/or transmitting data regarding items stored in storage bins in the second mobile container 700 and for storing, receiving and/or transmitting data regarding the location of each storage bin. The controller may also communicate with the container handling vehicles 201,301 via, for example, a wireless link.

The controller may also communicate with the master controller of the first mobile container 600 (e.g., via a wireless link) to transmit data relating to items stored in storage bins in the second mobile container 700 and data relating to the location of each storage bin.

The second container frame 700' of the second mobile container 700 shown in fig. 8 may be a prior art intermodal container as described above. It may be a 20 ' container, a 40 ' container or a 45 ' container as described above. When the second mobile container 700 is interconnected with another mobile container, at least a portion of one of the side walls of the second mobile container 700 needs to be removed in order for the container handling vehicle to move between the interconnected mobile containers.

The 20' container described in the prior art can store up to 279 boxes each 449mm wide, 649mm long and 220mm high.

The 20' container described in the prior art can store up to 186 boxes, each of which is 449mm wide, 649mm long and 330mm high.

A 40 'container as described in the prior art can store twice the number of storage bins that a 20' container can store.

Fig. 9 shows a mobile storage system having one first mobile container 600 and four second mobile containers 700 arranged side by side. This figure shows that when the mobile containers 600, 700 are removably connected, there is an opening at the connecting long end side panels 603, 703 of the two connected mobile containers 600, 700, or the connecting long end side panels are removed. In this regard, at least a portion of one of the long end side panels 603, 703 has been removed prior to or during attachment of the container frames 600', 700 and is removed as shown in fig. 9. After or during reattachment of the mobile container, the removed portion of the side panel is reassembled to close the opening.

Further, one of the short end side panels 604, 704 of the mobile container is shown with a door 605, 705 allowing access to the interior space of the respective container frame 600', 700. The long end side panels 603, 703 at the end of the system and not including the other mobile container 600, 700 connected thereto typically do not include openings.

Fig. 9 shows a mobile storage system with one master/first mobile container 600 connected to one supply/second mobile container 700, which is also connected to another supply container, which is connected to yet another supply container, etc. Thus, the mobile storage system may be customized to the desired storage.

Fig. 10 is an open top view of the mobile storage system shown in fig. 9. As can be seen, the openings in the connected long end side panels allow the first automated storage and retrieval system 500 and the second automated storage and retrieval system 500 ' to be interconnected so that the case handling vehicles 201,301 can move between the rail system 508 of the first grid structure 504 and the rail system 508' of the second grid structure 504 '.

If there is a gap between the first rail system 508 and the second rail system 508', the intermediate element 450 may be connected to the first rail system 508 and/or the second rail system 508', thereby allowing the case handling truck 201,301 to move thereon between the first rail system 508 and the second rail system 508 '.

For purposes of illustration, in fig. 10, the intermediate element 450 is shown suspended over the gap that it would cover when connected.

Fig. 11 shows an example of how an intermediate element 450 may connect a first rail 508'a of one rail system 508' with a second rail 508 'b of another rail system 508' of two adjacent second mobile containers 700. It should be understood that the same applies when connecting two rail systems between a first and a second moving container arranged adjacent to each other, or connecting two rail systems between two adjacent first moving containers.

Part (a) of fig. 11 shows two connected second mobile containers 700, wherein the rail system 508 'of one of the second mobile containers 700 has the intermediate element 450 connected thereto, but wherein the two rail systems 508' are not yet connected.

Part (b) of fig. 11 shows a detailed view of the circled area in part (a) of fig. 11, wherein the intermediate connecting element 450 is connected to the first rail 508'a of the first rail system 508' via a pivotal connection 460. The pivotal connection 460 is connected to the first rail 508' a and the intermediate connection element 450 via suitable fastening means known to those skilled in the art (e.g., a pivotal bracket 461 fastened by screws, bolts, pins, etc.).

In the disconnected state, in which the intermediate connecting element 450 is disconnected from the second rail 508 'b of the second rail system 508', the pivotal connection 460 and the intermediate connecting element 450 are pivoted in an upward direction with respect to the rail system 508', as shown in parts (a) and (b) of fig. 11, in which the two rail systems 508' of the two second moving containers are not connected.

In another example, not shown, the pivotal connection 460 may pivot to be placed in a downward position and may pivot upward to connect with another rail system 508'.

As disclosed in parts (a) to (d) of fig. 11, the intermediate connecting element 450 may be considered to form part of the first rail 508'a of one rail system 508' to which it is connected. In the solution disclosed in section (a) to (d) of fig. 11, the intermediate connection element 450 comprises a first end 451 and a second end 452. The second end 452 may be considered a receiving portion to be connected to a second rail 508 'b of another rail system 508'.

The receiving portion at the second end 452 of the intermediate connecting element 450 may include a notch (i.e., a female portion) that is complementary to the second rail 508' b (i.e., a male portion). Additionally, the first end 451 of the intermediate connecting member 450, which may be connected to the first rail 508'a, may be formed with a similar notch to provide some flexibility in the connection between the intermediate connecting member 450 and the first rail 508' a.

When the intermediate connecting element 450 is arranged to mainly horizontally connect a first rail 508'a of one rail system 508' and a second rail 508 'b of another rail system 508', the cooperation between the intermediate connecting element 450 and the first rail 508'a may be such that a portion of the intermediate connecting element 450 rests on the upper surface of the second rail 508' b. The surface is preferably substantially horizontal such that the intermediate connection element 450 provides a substantially flush drive rail for the case-loading truck 201,301 between the first rail 508'a and the second rail 508' b.

Part (c) to part (e) of fig. 11 show the intermediate member 450 in parts (a) and (b) of fig. 11, but the intermediate member 450 is in the connecting position such that the first rail 508'a and the second rail 508' b are connected.

Section (e) of fig. 11 is a top view of intermediate element 450 of fig. 11 in the connected position of sections (c) and (d).

In parts (d) and (e) of fig. 11, the recesses at the first end 451 and the second end 452 of the intermediate connecting element 450 and the complementary parts of the first rail 508'a and the second rail 508' b are shown in more detail. As shown, the connecting portion of the second rail 508' b may extend approximately half way into the recess of the second end 452 of the intermediate connecting member 450, thereby allowing some relative axial movement between the second rail 508' b and the first rail 508' when connected.

As shown in fig. 11, the intermediate linkage element 450 pivots between a linkage position and a non-linkage position.

The rail system in fig. 11 comprises a single rail in the Y-direction and a double rail in the X-direction, however, this is only an option, as there may be only a single rail or only double rails in both the X-direction and the Y-direction.

It should be noted that very high accuracy is required when connecting two automated storage and retrieval systems together. This is mainly due to the low flexibility of the box loading and unloading truck and the associated low tolerance to irregularities in the rail system. To avoid or at least reduce the possibility of interruptions during operation of the mobile storage system, the rails to be connected should be aligned as precisely as possible. When viewing the connection of the first and second rails 508'a, 508' b in fig. 11, both the first and second rails 508'a, 508' b should have the same Z-coordinate and the same axis in the X-direction for enabling the box-handling vehicle to move from one rail system 508 'to the other rail system 508'. Their difference in position at the point where the first 508'a and second 508' b rails are connected should preferably not exceed 1/10mm in the Y direction.

When connected, the axial flexibility of the intermediate element 450 allows relative movement in the X direction between the first and second rails 508'a, 508' b, e.g. +/-40mm, +/-15mm or more or less.

Fig. 12 is a top view of the mobile storage system of fig. 9 and 10 showing the top panels 602, 702.

Fig. 13 shows how mobile containers may be arranged side by side with four coupling/connecting devices 400 arranged between the mobile containers to be connected. This exemplary aspect shows a connection between the first mobile container 600 and the second mobile container 700, but the connection would be the same if two first mobile containers 600 or two second mobile containers 700 were connected together in a side-by-side arrangement.

Since the above accuracy is high when connecting two automated storage and retrieval systems together as shown in fig. 11, the connection of two mobile containers as shown in fig. 13 should also have a high accuracy, which means that the first mobile container 600 and the second mobile container 700 should have equal Z-and Y-coordinates and be arranged in parallel in the X-direction.

As already mentioned above with respect to fig. 9, at least a portion of one of the long end side panels of the first and second mobile containers 600, 700 may be removably connected to the container frame 600', 700. As shown in fig. 9, the entire long end side panel is removed, however, in order for the system to be operable, only a portion of the panel needs to be removed to form an opening so that the container handling vehicle can be moved from the rail system of one moving container to the rail system of another moving container. Thus, in this mobile storage system, when the system comprises two or more mobile containers arranged side by side, the size of the opening should be at least the size of the largest cross-section (taken in a vertical plane perpendicular to the axis of movement of the container-loading vehicle when moving through the opening, said vertical plane being parallel to the plane of the panel in which the opening is formed) of the container-loading vehicle carrying the containers moving on the rail system. Furthermore, the openings should of course be positioned accordingly, i.e. so that the container handling vehicle can be moved from the rail system of one moving container to the rail system of another moving container.

In the exemplary embodiment shown in fig. 13, the long end side panel corresponding to the connecting vertical face of the moving container is removed, creating an opening that is larger than the vertical dimension of the rail system with the container loading truck of the carrying case moving thereon.

The base panels of the first and second mobile containers 600 and 700 each have a rectangular parallelepiped shape. Thus, each base panel has a length and width defining upper and lower surfaces of the base panel, and a depth (i.e., vertical extent) extending between the upper and lower surfaces of the base panel.

The top panels of the first and second mobile containers 600 and 700 each have a rectangular parallelepiped shape. Thus, each top panel has a length and width defining upper and lower surfaces of the top panel, and a depth (i.e., vertical extent) extending between the upper and lower surfaces of the top panel.

The vertically extending profiles of the first and second moving containers 600 and 700 each have a rectangular parallelepiped shape. Thus, each vertically extending profile has a length and a width defining an upper surface and a lower surface of the vertically extending profile, and a depth (i.e., vertical extent) extending between the upper surface and the lower surface of the vertically extending profile.

Furthermore, the vertical extent of the base panel 601 of the first mobile container 600 facing the vertical extent of the base panel 701 of the second mobile container to which it is to be connected has at least one hole 401 for inserting a coupling device 400 in a close-fitting configuration, the coupling device having the shape of a connecting pin. Similarly, a corresponding hole is provided in the vertical extent of the base panel 701 of the second mobile container.

Although the figure shows that the first and second mobile containers comprise holes for connecting coupling means arranged within the vertical extent of the base panel, it will be appreciated that the connection may alternatively or additionally be made by arranging the holes within any vertical extent of the top panels and/or the vertically extending profiles of the first and second mobile containers which face each other when connected.

In other words, the holes may be distributed in any arrangement along the frame of the moving containers facing each other during connection, allowing a tight fitting configuration after inserting the coupling device and connecting the two moving containers.

The hole 401 has a funnel shape and the pin 400 is configured to match at least the smallest diameter of the funnel-shaped hole 401, thereby forming a tight fit.

The pin shown in fig. 13 has a smaller cross-section at its end than at its midpoint, so that the cross-section of the pin 400 expands from the end of the pin 400 to the midpoint, which corresponds to a funnel-shaped opening.

The diameter of the cross-section at the midpoint may be at least 1.05 times larger than the diameter of the cross-section at the end of the connecting pin, preferably at least 1.07 times larger, more preferably at least 1.09 times larger.

The diameter of the cross-section of the pin at the midpoint may be, for example, from 4cm to 10cm, the diameter of the cross-section of the end portion may be from 2cm to 7cm, and the total length of the pin may be from 10cm to 50 cm.

In one example, the diameter of the cross-section of the pin at the midpoint is 5.5cm, the diameter of the cross-section of the end is 5cm, and the total length of the pin is 25 cm.

The number of holes and connecting pins to be inserted into the holes varies depending on the size of the mobile container to be connected.

In an exemplary embodiment of connecting two 20' mobile containers, the mobile containers comprise two holes distributed along the connecting surface of the base panels of the two mobile containers, and two pins are inserted into these holes during the connection.

Further, the pins 400 may be retractable, and then will be in a retracted state when a moving container is to be removed from the system, and will be in an extended state when a moving container is connected or being connected to the system. When the pin is in its retracted state, it does not protrude outside the frame of the moving container into which it has been inserted.

Part (a) of fig. 14 shows a second mobile container 700 having a second storage and retrieval structure 500' arranged on top of a base plate 950. The base plate 950 is arranged on top of the base plate 701 of the second moving container 700. Due to the high precision required when connecting two automated storage and retrieval systems, the substrate 950 may be horizontally displaced, allowing for horizontal displacement of the automated storage and retrieval structures disposed thereon. The substrate 950 may be made of, for example, fiberboard, hardboard, etc., and may be 10mm to 100mm thick, such as 25mm or 30mm thick.

Part (b) of fig. 14 shows a detailed view of the circled area in part (a) of fig. 14. Part (b) of fig. 14 shows how the substrate 950 is horizontally displaced in the Y direction by using one or more adjusting devices 951. The adjustment device 951 is rigidly secured to the base plate 700 and the base plate 950 using brackets 952, 953.

As shown in part (b) of fig. 14, the adjusting device 951 may include: an intermediate bracket 952 connected to an upper surface of the base plate 701; and two side brackets 953 connected to the base panel 950 disposed on each side of the middle bracket 952. The rod 954 passes through holes in each of the three cradles such that the rod is displaceable in the horizontal Y-direction, thereby restricting movement in the Z-direction and the X-direction. With this arrangement, the stem 954 may be displaced by loosening and tightening a fixture (e.g., a nut), which in this case is attached to the threaded stem 954, on both sides of the middle mount 952 and on one side of the side mounts 953. Nuts attached to the rods, the middle mount 952 and the side mounts 953 may also rigidly secure the rods 954 in a desired position, thereby rigidly securing the base plate 950 to the base plate 701. When the rod 954 is displaced, the base plate 950 will be displaced accordingly, allowing fine adjustment in the Y-direction of the automated storage and retrieval structure 500' placed thereon.

A similar adjustment device 951 may be provided on the opposite side of the base plate 950, in which case two adjustment devices 951 may be adjusted in series.

Alternatively, one or more adjustment devices 951 may be provided on adjacent sides to allow horizontal movement in the X direction.

Thus, the base plate 950 may be provided with one or more adjustment devices 951 to allow horizontal movement in the X-direction and/or the Y-direction.

Part (a) of fig. 15 shows a first moving container and a second moving container arranged on the height adjustable foot 960. Feet 960 are placed at each corner at the lower surface of the base plates 601, 701 of the first and second mobile containers 600, 700, allowing leveling of the first and second mobile containers 600, 700 to provide a substantially flush lower surface between the base plates 601, 701 of the first and second mobile containers 600, 700.

Part (b) of fig. 15 shows a detailed view of the exemplary height adjustable foot 960 shown in part (a) of fig. 15. Foot 960 includes stand 961, which includes lower base 967 for standing/resting on the ground. The stand includes at least two side walls 962 extending vertically from opposite sides of a base 967, and the at least two side walls 962 are interconnected by a bridge 963 including a hole 964 in a center thereof. The rod 965 is disposed inside the hole 964 of the bridge 963 and is displaceable in the vertical Z direction, thereby restricting movement in the horizontal X and Y directions. The pole 965 has a shelf 966 disposed above the bridge 963, allowing a mobile container to rest thereon. With this arrangement, the stem 954 may be displaced by loosening and tightening a fixture (e.g., a nut) that in this case is attached to the threaded stem 954 and to both sides of the bridge 963 of the cradle 961. As shown, the rod may pass through a hole 965 disposed at the center of the base 967 of the bracket 961. Furthermore, the rod 965 may be secured at its upper end to the mobile container, for example by welding or using an attachment means.

When the lever 964 is displaced, the part of the moving container arranged on the feet 960 will be displaced accordingly, allowing fine adjustment in the Z-direction of the moving container.

When a plurality of mobile containers are arranged in a side-by-side arrangement and height adjustable feet are placed under each corner of the base plate of each mobile container, the mobile containers may all be arranged such that the outer surfaces of the base panels of two mobile containers connected to each other are flush with each other during and after connection.

Although the height adjustable feet have been described as being placed under each corner of the base plate of each mobile container, they may alternatively be provided at other locations around the bottom perimeter of the base plate of each mobile container.

Part (a) of fig. 16 shows a perspective view of a mobile storage system in which supply containers 700 are arranged on top of other supply containers 700. As shown in part (a) of fig. 16, the mobile storage system may include a first row of a plurality of mobile containers arranged in a side-by-side arrangement, and a plurality of mobile containers arranged in a side-by-side arrangement in a second row located at the top of the first row.

Part (b) of fig. 16 is a detailed view of the pin 400 shown in fig. 13.

Fig. 17 shows two moving containers arranged on top of each other. The upper moving container is the second moving container 700 (supply container) and the lower moving container may be the first (main) moving container or the second (supply) moving container, however, the figure shows two second moving containers arranged on top of each other.

Fig. 17 shows that one upper second moving container 700U is arranged directly above another lower second moving container 700L, such that a corner of the base panel 701U of the upper second moving container 700U is arranged directly above a corresponding corner of the top panel 702L of the lower second moving container 700L. In order to allow the storage bin 106 to move between the upper second moving container 700U and the lower second moving container 700L, the base panel 701U of the upper second moving container 700U has a bin opening (910, see part (a) of fig. 18) to allow the storage bin 106 to pass therethrough, and the top panel 702L of the lower second moving container 700L may have a corresponding bin opening (910, see part (a) of fig. 18) for the same purpose. The container handling carts 201,301 arranged on the rail system in the upper second moving container 700U may use lifting means within the container handling carts 201,301 to lower the storage bin 106 through the bin opening from the upper second moving container 700U into the lower second moving container 700L.

The storage box handling device 900 is arranged in connection with the rail system 508' in the lower second mobile container 700L. An exemplary operation of moving the storage box 106 between the upper second moving container 700U and the lower second moving container 700L will be described in detail in fig. 18 and 19.

Parts (a) and (b) of fig. 18 show a part of the upper second moving container 700U arranged on top of the lower second moving container 700L as shown in fig. 17.

Part (a) of fig. 18 further shows the storage box 106 attached to the lifting system on the cantilevered box handling vehicle 301. The lifting system has an attachment structure 302 (see fig. 19) connected to a box-loading wagon 301 by means of adjustable wires or straps (not shown). The attachment structure 302 is provided with a set of gripping devices 303 adapted to engage with the storage bin 106 and means for controlling each gripping device 303. The gripping device 303 of the lifting system is connected to the bin loader truck 301 and ensures vertical transport of the storage bin 106, such as lifting the storage bin 106 from the storage pole and lowering the storage bin 106 into the storage pole.

The attachment structure 302 with the gripping device 303 may be lowered from the box-loading and unloading vehicle 301 such that the position of the gripping device 303 relative to the box-loading and unloading vehicle 301 may be adjusted in a third direction Z orthogonal to the first direction X and the second direction Y.

Part (b) of fig. 18 shows the bin loader truck 301 having lowered the attachment structure 302 and the storage bin 106 connected thereto into the storage bin opening 910.

Part (c) of fig. 18 shows a storage box handling device 900 arranged on top of the rail system 508' of the lower second moving container. The storage box handling device 900 receives and/or delivers storage boxes from and/or to the upper second moving container, respectively. The storage bin handling device 900 includes vertically extending baffles 901 for guiding the storage bin in a vertical direction between the bin opening 910 of the lower moving container and the rail system 508'. The storage bin unloader 900 further includes a bin moving structure 902, such as a bin conveyor 902, for moving the bins to and from the bin unloader to a bin lift position 903 on the rail system 508' in the lower second moving container, where the storage bin can be picked up or delivered by the bin unloader. Thus, the bin conveyor 902 transports the storage bins horizontally between the storage bin handling device 900 and the bin lift position 903 within the lower second moving container's rail system 508'. When placing the storage bin in the bin lift position 903, the bin unloader may pick up the storage bin and move it to a target position within the storage grid structure of the lower second mobile container 700L. The case-loading truck may also deliver the storage box to a box-lifting position for moving the storage box to a position inside the storage-box-handling device 900 so that the storage box is picked up by the gripping device connected to the case-loading truck disposed in the upper second moving container 700U, and then move the case-loading truck including the storage box to a target position of the storage box within the storage grid structure of the upper second moving container.

The box conveyor 902 shown in part (c) of fig. 18 has a conveyor belt 904 to which a box resting device 905 is attached. The bin resting device 905 may be any type of device that allows a bin to move in a horizontal direction from its position adjacent the bin loading and unloading device 900 to the bin lift position 903.

Part (a) to part (e) of fig. 19 illustrate an exemplary process in which the storage box handling device 900 located on top of the rail system 508 'of the lower second mobile container 700L receives a storage box 106 from a box handling car 301 located on the rail system 508' of the upper mobile container 700U; and how to remove the storage bin 106 from a position adjacent to the storage bin handling device 900 to a bin lift position 903 where another bin handling vehicle 301 arranged on top of the rail system 508' of the lower second moving container 700L can pick up the storage bin.

In part (a) of fig. 19, the storage box handling device 900 is empty and ready to receive a storage box.

Part (b) of fig. 19 shows the storage bin 106 placed adjacent to the bin handling device 900, see fig. 17, after the storage bin has been delivered from the bin handling vehicle arranged in the upper second mobile container 700U. The attachment structure 302 of the bin loader truck remains connected to the storage bin 106.

Part (c) of fig. 19 shows the attachment structure 302 including the gripping device 303 after releasing the storage bin 106 therefrom. The storage bins 106 are placed on a rest 905 of the bin conveyor 902 at the bin unloader 900.

Part (d) of fig. 19 shows the storage bin disposed at the bin lift position 903 after being conveyed from a position adjacent to the bin unloader 900 to the bin lift position 903 by the conveyor belt 904 of the conveyor 902.

Part (e) of fig. 19 shows how the bin loader/unloader 301 may be able to pick up the storage bin 106 from the bin lift position 903.

Although fig. 18 and 19 show a cantilevered bin loader, a single unit bin loader 201 could of course be used for the same purpose.

Fig. 20 shows a mobile storage system with a first mobile container 600 (main container) and four second mobile containers 700 (supply containers) connected in a side-by-side arrangement, wherein the system comprises two equipment containers 800 for storing equipment (such as air conditioning systems, generators, fire extinguishing systems). The equipment container 800 is connected to the first mobile container 600 at the opposite side of the connection to the second mobile container 700.

As can be seen from the drawings of the exemplary mobile storage system, the mobile storage system provides a flexible system in which mobile containers arranged at either end of a side-by-side arrangement can be replaced with another mobile container. For example, by looking at a system comprising one master container and four supply containers arranged in a side-by-side arrangement as shown in fig. 12, the grid structure of both the master container and the supply containers can be considered as full storage bins containing cargo. As system operating time elapses, more and more items are removed from bins within the system. If the system is then operated in such a way that all empty storage bins are positioned within the supply containers arranged at the ends of the side-by-side arrangement, either by replacing the storage bins containing the goods or by occupying the available space of the empty storage bins to be arranged, the supply container receiving all empty storage bins will fill with empty storage bins as the operating time passes. The supply container may then be removed and replaced with another supply container having a storage bin with goods.
