Abstract
Description
[0001] This application is a divisional application of Chinese Patent Invention Application No. 202080043125.6, filed on May 7, 2020, entitled "Storage System". Technical Field
[0002] This invention relates to an automatic storage and retrieval system and a method of using the automatic storage and retrieval system. Background Technology
[0003] Figure 1 A and Figure 2 B discloses a typical prior art automated storage and retrieval system 1 with a frame structure 100. Figure 1 B and Figure 2 B disclosed in Figure 1 A and Figure 2 The prior art container handling vehicles 200 and 300 that operate in System 1 disclosed in A.
[0004] The frame structure 100 defines a storage grid 104, which includes a plurality of upright members 102 and optionally a plurality of horizontal members 103 supporting the upright members 102. Members 102, 103 may typically be made of metal, such as extruded aluminum profiles.
[0005] Storage grid 104 includes multiple grid columns 112. Most of the grid columns are also referred to as storage columns 105, in which storage containers 106, also referred to as boxes, are stacked one on top of another to form a stack 107.
[0006] Each storage container 106 can typically hold multiple product items (not shown), and depending on the application, the product items within the storage container 106 can be the same or can be different product types.
[0007] Storage grid 104 prevents horizontal movement of storage containers 106 in stack 107 and guides vertical movement of containers 106, but typically does not support storage containers 106 when stacked.
[0008] The automated storage and retrieval system 1 includes a track system 108 (or top track grid) arranged in a grid pattern on top of a storage grid 104, on which multiple container handling vehicles 200, 300 (e.g., Figure 1 B and Figure 2 (Example B) This involves lifting the storage container 106 from the storage column 105 and lowering the storage container 106 into the storage column, and also transporting the storage container 106 above the storage column 105. The horizontal extension of one of the grid cells 122 constituting the grid pattern extends to... Figure 1 A and Figure 2 The letter A is marked with a thick line.
[0009] Each grid cell 122 has a width typically in the range of 30 to 150 cm and a length typically in the range of 50 to 200 cm. Due to the horizontal extension range of the tracks 110, 111, the width and length of each grid opening 115 are typically 2 to 10 cm smaller than the width and length of the grid cell 122.
[0010] The track system 108, also known as the top track grid, includes a first set of parallel tracks 110 arranged to guide container handling vehicles 200, 300 to move along a first direction X on top of the frame structure 100, and a second set of parallel tracks 111 arranged perpendicular to the first set of tracks 110 to guide container handling vehicles 200, 300 to move along a second direction Y perpendicular to the first direction X. Thus, the track system 108 defines the upper end of the grid column 112, above which the container handling vehicles 200, 300 can move laterally, i.e., in a plane parallel to the horizontal XY plane. Typically, at least one set of track groups 110, 111 consists of dual-track rails, thereby allowing two container handling vehicles to pass each other on adjacent grid cells 122. Dual-track rails are known and disclosed, for example, in WO 2015 / 193278A1 and WO 2015 / 140216A1, the contents of which are incorporated herein by reference.
[0011] Figure 3 The diagram illustrates a grid cell 122 defined when both sets of tracks in the track system are dual-guided tracks. In this track system, even if another container handling vehicle 200 is located above a grid column adjacent to a row of grid columns, a container handling vehicle 200 with a maximum perimeter adapted within the lateral region defined by the grid cell 122 is allowed to travel along that row of grid columns. Each grid cell 122 includes a grid opening 115 defined by a pair of tracks 110a, 110b of a first set of parallel tracks 110 and a pair of tracks 111a, 111b of a second set of parallel tracks 111. Figure 3 In the diagram, grid cell 122 is indicated by a dashed box.
[0012] Therefore, track 110a and track 110b form an adjacent track pair defining parallel rows of grid cells extending in the X direction, and track 111a and track 111b form an adjacent track pair defining parallel rows of grid cells extending in the Y direction.
[0013] Each prior art container handling vehicle 200, 300 includes a vehicle body and a wheel assembly with eight wheels, wherein a first set of four wheels 32a enables the container handling vehicle 200, 300 to move laterally in the X direction, and a second set of four wheels 32b enables lateral movement in the Y direction. One or two sets of wheels in the wheel assembly can be raised and lowered, such that the first set of wheels and / or the second set of wheels can engage with a corresponding set of tracks 110, 111 at any given time.
[0014] Each prior art container handling vehicle 200, 300 also includes a lifting device 34 (only in...). Figure 2 (As shown in B), it is used for vertical transport of storage container 106, such as lifting storage container 106 from grid column 112 and lowering storage container 106 into grid column 112. Lifting device 34 includes four metal lifting straps 31 extending vertically and connected near the corners of lifting frame 33 (also referred to as clamping device) to keep the lifting frame horizontal. Lifting frame 33 is characterized by container connecting elements 35 for releasable connection to storage container 106 and guide pins 30.
[0015] Traditionally, and also for the purposes of this application, Z=1 identifies the uppermost layer of grid 104, that is, the layer directly below the orbital system 108; Z=2 identifies the second layer below the orbital system 108; Z=3 identifies the third layer, and so on. Figure 1 A and Figure 2 In the prior art storage grid disclosed in A, Z=8 identifies the bottommost layer of grid 104. Therefore, as an example, and using... Figure 1 A and Figure 2 The Cartesian coordinate system X, Y, Z indicated in B. Figure 1 The storage container marked 106' can be said to occupy a grid position or cell X=10, Y=2, Z=3. Container handling vehicles 200 and 300 can be said to travel in layer Z=0, and each grid column can be identified by its X and Y coordinates.
[0016] Each container handling vehicle 200 includes a storage compartment or space (not shown) for receiving and loading storage containers 106 when transported on top of storage grid 104. The storage space may include a cavity centrally located within the vehicle body, for example, as described in WO2014 / 090684A1, the contents of which are incorporated herein by reference.
[0017] Alternatively, the container handling vehicle 300 may have a cantilever structure as described in NO317366, the contents of which are also incorporated herein by reference.
[0018] The container handling vehicle 200 may have a coverage area, i.e. an extension in the X and Y directions, which is substantially equal to the horizontal area of the grid cell 122, i.e. the extent of the grid cell 122 in the X and Y directions, as described, for example, in WO2015 / 193278A1, the contents of which are incorporated herein by reference.
[0019] Alternatively, the container handling vehicle 200 may have a coverage area greater than the horizontal area of the grid cell 122, as disclosed in WO2014 / 090684A1.
[0020] In storage grid 104, most grid columns 112 are storage columns 105, i.e., grid columns where storage containers 106 are stored in stacks 107. However, grid 104 typically has at least one grid column 112 that is not used to store the storage container 106, but is arranged at a location where container handling vehicles 200, 300 can unload and / or pick up the storage container 106, allowing it to be transported to a second location (not shown) where the storage container 106 can be accessed from outside grid 104 or transferred out of or into grid 104. In the art, such a location is generally referred to as a "port," and the grid column where the port is located may be referred to as transfer columns 119, 120. The unloading and picking port is the upper end / opening of the corresponding transfer column 119, 120.
[0021] Figure 1 A and Figure 2 The prior art storage grid 104 in A includes two transfer columns 119 and 120. The first transfer column 119 may include, for example, a dedicated unloading port where container handling vehicles 200, 300 can unload storage containers 106 to be transported via transfer column 119, and further unload them to, for example, a pick-up / storage station. The second transfer column 120 may include a dedicated pick-up port where container handling vehicles 200, 300 can pick up storage containers 106 that have already been transported from, for example, a pick-up / storage station via transfer column 120. Storage containers can be transported through the transfer columns using lifting devices of container handling vehicles 200, 300 or by using storage container lifting devices arranged in the transfer columns. Each port of the first and second transfer columns can be adapted for the pick-up and unloading of storage containers.
[0022] The second location is typically a pick-up / storage station, where product items are removed from and / or located in storage container 106. In the pick-up / storage station, storage container 106 is typically never removed from the automated storage and retrieval system 1, but is returned to storage grid 104 once retrieved.
[0023] In order to monitor and control the automated storage and retrieval system 1, for example, to monitor and control the position of the corresponding storage containers 106 within the storage grid 104; the contents of each storage container 106; and the movement of the container handling vehicles 200, 300 such that the desired storage container 106 can be delivered to the desired location at the desired time, and the container handling vehicles 200, 300 do not collide with each other, the automated storage and retrieval system 1 includes a computer control system (not shown) that typically includes a database for tracking the storage containers 106.
[0024] A conveyor system including a conveyor belt or rollers is typically used to transport storage containers from the lower end of transfer columns 119, 120 to, for example, a pick-up / storage station.
[0025] The transport system can also be arranged to transfer storage containers between different storage grids, as described in, for example, WO2014 / 075937A1, the contents of which are incorporated herein by reference.
[0026] Furthermore, WO2016 / 198467A1, the contents of which are incorporated herein by reference, discloses examples of prior art access systems having a conveyor belt (as described in WO2016 / 198467A1). Figure 5 a and Figure 5 b) and the framed track (in WO2016 / 198467A1) Figure 6 a and Figure 6 b), used for transporting storage containers between transfer columns and stations where operators can access the storage containers.
[0027] When you need to access the stored Figure 1When a storage container 106 is in the storage grid 104 disclosed in A, one of the container handling vehicles 200, 300 is instructed to retrieve the target storage container 106 from its position in the grid 104 and transport it to or through the transfer column 119. This operation includes moving the container handling vehicles 200, 300 to the grid position above the storage column 105 where the target storage container 106 is located, retrieving the storage container 106 from the storage column 105 using a lifting device (not shown) of the container handling vehicle, and transporting the storage container 106 to the transfer column 119. If the target storage container 106 is located deep within the stack 107, i.e., one or more other storage containers are positioned above the target storage container 106, the operation also includes temporarily moving the storage container positioned above before lifting the target storage container 106 from the storage column 105. This step, sometimes referred to in the art as "digging," can be performed using the same container handling vehicles 200, 300 subsequently used to transport the target storage container 106 to the transfer column, or using one or more other cooperating container handling vehicles 200, 300. Alternatively or additionally, the automated storage and retrieval system 1 may have container handling vehicles 200, 300 specifically designed for the task of temporarily removing the storage container 106 from the storage column 105. Once the target storage container 106 has been removed from the storage column 105, the temporarily removed storage container can be repositioned back into the original storage column 105. However, the removed storage container can alternatively be relocated to another storage column 105.
[0028] When storage container 106 is to be stored in grid 104, one of the container handling vehicles 200 or 300 is instructed to pick up storage container 106 from transfer column 120 and transport it to a grid location above storage column 105, where the storage container is stored. After any storage containers located at or above the target location within storage column stack 107 have been removed, container handling vehicles 200 or 300 position storage container 106 in the desired location. The removed storage container can then be lowered back into storage column 105 or repositioned to another storage column 105.
[0029] A common operation performed in existing storage systems is to consolidate multiple different items picked up from a storage grid, such as consolidating multiple items belonging to a single customer order. These multiple items are then consolidated for further processing, such as packaging them in a single parcel for shipment to the customer.
[0030] In existing systems, the consolidation of multiple items is performed by first transferring storage containers containing the items from a storage grid to a manual pick / store station in a specific order. At the pick / store station, the operator picks the required items for an order and places them in a single package for further processing, such as shipment to a customer. Different items to be consolidated are typically stored in different storage containers, and the speed of the consolidation process is therefore limited by the speed at which different storage containers become available at the pick / store station. Furthermore, due to the sequential access to different storage containers, identical orders with the same items from the same storage container are not processed much faster than dissimilar orders, because for each order, the storage container must be circulated between the pick / store station and the storage grid.
[0031] The efficiency of existing consolidation methods is not optimal for several other reasons. Pick-up / storage stations and the areas required for item consolidation must be arranged adjacent to each other so that operators can easily move items between the pick-up / supply station and the packages in which items are consolidated. Existing pick-up stations are arranged around the perimeter of the storage grid, and the locations of the pick-up / supply station and the areas required for item consolidation are set, for example, for conveyors transporting packages for consolidation. This positioning can be disadvantageous when the storage system must be adapted to a given building layout. Alternatively, the areas required for item consolidation, such as the conveyors transporting packages for consolidation, could be located in separate locations, but this would significantly reduce the efficiency of the consolidation process.
[0032] In view of the foregoing, the objective of the present invention is to provide a storage system and a method for operating such a system, which solves or at least mitigates one or more of the aforementioned problems associated with the use of prior art storage systems.
[0033] The object of this invention is to provide a storage system that is more efficient than existing systems in integrating items retrieved from the storage system.
[0034] Another objective is to provide a more flexible storage system. Summary of the Invention

[0169] In the following, embodiments of the invention will be discussed in more detail with reference to the accompanying drawings. However, it should be understood that the drawings are not intended to limit the invention to the subject matter depicted therein. Furthermore, even though some features are described only with respect to the system, it is clear that they are effective for related methods, and vice versa.
[0170] The present invention aims to provide a storage system with improved and efficient item retrieval integration.
[0171] Figures 4 to 7 The image shows a first exemplary embodiment of a storage system according to the present invention. The storage system is characterized by a storage grid structure 104 on which a plurality of container handling vehicles 300 are arranged.
[0172] The storage grid structure includes vertical column profiles 102 defining multiple storage columns 105, wherein storage containers 106 are stored one on top of another in a vertical stack 107. The storage grid is further characterized by at least one transfer column (see...). Figure 12 An exemplary transfer column), the at least one transfer column being arranged to allow storage containers to be moved out and in from the storage grid.
[0173] The column profiles 102 are interconnected at their upper ends by top rails 110 and 111, which form a horizontal top rail grid 108. The container handling vehicle 300 can move along the top rail grid in two vertical directions. The container handling vehicle can retrieve the storage container 106 from the storage column 105 and store the storage container in the storage column 105, and transport the storage container on the storage grid structure 104.
[0174] To achieve efficient integration of items picked up from storage containers, the storage system has multiple integration vehicles 6, a transfer track grid 5, an item pickup area 7, and an item delivery station 8.
[0175] The transfer track grid 5 consists of transfer tracks 110' and 111', and the integrated vehicle 6 can move along two vertical horizontal directions on these transfer tracks.
[0176] The item pickup area 7 includes a first segment 9 of a transfer track grid on which the integration vehicle 6 can be positioned to receive items 21 picked up from any storage container 106 placed within reach of a robotic pickup arm 11 (i.e., an item pickup). Each robotic pickup arm is arranged to pick up items from storage containers 106 placed below it and transfer them to the integration vehicle 6. In the case of completing an order comprising multiple items, the multiple items are transferred to the same integration vehicle 6.
[0177] Once all items in an order have been transferred to the consolidation vehicle, the consolidation vehicle is moved along the transfer track grid to the item conveying station for further order processing. The item conveying station is characterized by a second segment 10 of the transfer track grid 5, on which the consolidation vehicle 6 can be positioned to convey items from the order received from the storage container to the packaging / processing component 12. Therefore, the combination of the consolidation vehicle 6 and the transfer track grid 5 provides highly flexible positioning for both the item conveying station 8 and the packaging / processing component 12.
[0178] exist Figures 4 to 7 In the exemplary storage system shown, item 21 can be conveyed to packaging / processing component 12 via belt conveyor 20 or opening 19. The preferred method of conveying item to packaging / processing component 12 may depend on the layout of the storage system and the available space in the building housing the storage system.
[0179] exist Figures 4 to 7 A detailed view of the exemplary integrated vehicle 6 used in the storage system is shown below. Figure 8 As shown. The integrated carrier 6 includes an item rack 13 with an open top 17, four side walls 14, 15 (i.e., peripheral side walls), and a conveyor belt 22 (i.e., a laterally movable surface and / or item transfer assembly) arranged at the bottom section of the item rack. One of the side walls 15 is hinged to the upper section of the item rack 13 and connected to an actuator 18, allowing the side wall to move between an open position and a closed position. Figure 6 and Figure 7 As shown, when the conveyor belt 22 is activated and the openable sidewall 15 is in the open position, the items 21 arranged in the item rack 13 can be emptied.
[0180] The integrated vehicle 6 is characterized by motorized wheel assemblies 32a and 32b, which allow the vehicle to move along two perpendicular directions on the transfer grid 5. These wheel assemblies are similar to those of prior art container handling vehicles 200 and 300 disclosed, for example, in NO317366B1 and WO2015 / 193278A1, and can optionally be motorized using hub motors as disclosed in WO2016 / 120075A1.
[0181] The transfer track grid consists of dual guide rails 110' and 111', and the integrated carrier 6 has a horizontal perimeter that fits within a horizontal area defined by the grid cells 122' of the transfer track grid 5. This solution is efficient because two integrated carriers 6 can pass over each other on any adjacent grid cells 122' of the transfer track grid 5, requiring minimal deviation from the shortest path between two locations on the transfer grid. Furthermore, multiple integrated carriers 6 can be arranged in adjacent grid cells of the item pickup area, allowing the robotic pickup arm to reach multiple integrated carriers by moving the shortest possible distance between the integrated carrier and the storage container. The latter provides a very time-efficient pickup process.
[0182] Depending on the type of container handling vehicles 200 and 300 used on the storage grid structure, the top track grid 108 may be the same as or different from the transfer track grid 5. For example, the top track grid may differ from the transfer track grid, characterized by a first set of tracks being single-rail tracks and a second set of tracks being double-rail tracks, as described in the background section. However, regardless of whether the top track grid is the same as the transfer track grid, the track grids are arranged separately from each other to prevent the container handling vehicle 300 from entering the transfer track grid 5 and to prevent the consolidation vehicle 6 from entering the top track grid 108. Figures 4 to 7 In the exemplary storage system, the transfer track grid 5 is separated from the top track grid 108 by being positioned at different horizontal levels. Separating the track grids is highly advantageous for several reasons. The first advantage of separating track grid 5 from track network 108 is that consolidation operations performed on the transfer track grid can be stopped without affecting operations unrelated to consolidation performed on storage grid 104, such as retrieving storage containers and transporting them to a manually operated pick-up / supply station (not shown). This ensures minimal downtime for the storage system. It should be noted that if container handling vehicles 200, 300 have approached the transfer track grid, the entire storage system must be shut down for, for example, maintenance of equipment positioned on the transfer track grid. A second advantage is that the control system is simplified because the consolidation vehicles can be controlled and moved without having to consider the movement of the container handling vehicles.
[0183] In other implementations of the storage system, the transfer track grid and the top track grid may be at the same horizontal level, but separated by having a blocking element (e.g., a fence) arranged between the two grids or by being arranged at a distance from each other.
[0184] Figures 9 to 11 A second exemplary embodiment of the integrated carrier 6' is shown. The integrated carrier 6' is characterized by wheel assemblies 32a, 32b that allow the carrier to move in two vertical directions on the transfer grid 5, and includes an item rack 13 having an open top 17, four side walls 14, 15 (i.e., peripheral side walls), and an openable bottom section 16 (i.e., item transfer assembly). The bottom section 16 is connected to an actuator 18 arranged to keep the bottom section in a closed position (see...). Figure 9 ) and opening location (see Figure 10 and Figure 11 The wheels move between the sections. To make room for the openable bottom section, the wheel assembly is motorized by a hub motor in each wheel.
[0185] In use, the consolidation carrier 6' can first be positioned at the item pickup area to receive items to be consolidated, and then move to the item conveyor station, which is located above the opening 19, for conveying the items to the packaging / processing assembly 12 by opening the bottom section 16. Although not shown, the opening 19 may, in some cases, be positioned above the conveyor for further transporting the items 21 to the packaging / processing assembly 12.
[0186] Figure 15 A third exemplary embodiment of the "integration carrier 6" is shown. The "integration carrier 6" is characterized by wheel assemblies 32a, 32b that allow the carrier to move in two perpendicular directions on a transfer grid 5, and includes an item carrier 13 comprising a roller conveyor 25 (i.e., an item transfer assembly) arranged at the bottom section of the carrier. The "integration carrier 6" is particularly suitable for directly integrating items, for example, those in top-open packaging boxes 26 (schematically depicted in dashed lines) arranged on the item carrier 13, and is also suitable for transferring large items to be integrated at the packaging / processing assembly 12. In use, packaging boxes or large items can be transferred from the integration carrier to the conveyor 20 at the item transport station 8 by actuating the roller conveyor 25.
[0187] Depend on Figures 4 to 7The consolidation operation performed by the exemplary storage system may include the following steps: positioning consolidation carriers 6, 6' at the first segment 9 of transfer track grid 5; transferring a first item 21 from a first storage container 106 to the item rack 13 of the consolidation carriers 6, 6' using a robotic pickup arm; transferring a second item 21 from the first storage container 106 or from the second storage container 106 to the item rack 13 of the consolidation carriers 6, 6' using a robotic pickup arm; moving the consolidation carriers 6, 6' to the second segment 10 of transfer track grid 5; and opening the openable sidewall 15 or bottom segment 16 (i.e., opening the openable segment of the item rack) so that the first and second items 21 are emptied from the item rack 13 in a lateral or downward direction. When emptied from the item rack, the items can be transferred to a conveyor arrangement, such as a conveyor belt or rollers.
[0188] In an alternative consolidation operation, the consolidation of items can also be performed at the packaging / processing component 12. For example, by transferring a first item to a first consolidation carrier 6, 6' and a second item to a second consolidation carrier 6, 6'. The first and second consolidation carriers can then be moved to empty the first and second items respectively at the same item transport station 8, such that the items are consolidated at item transport station 8 or packaging / processing component 12. An alternative consolidation process may include multiple consolidation carriers, each used to transfer one fewer item.
[0189] Figures 12 to 14 A second exemplary embodiment of the storage system is illustrated. In this second exemplary embodiment, a storage container 106 containing an item 21 to be picked up is first transferred from a storage grid 104 to a container transfer carrier 23 arranged on a third segment 24 of a transfer track grid 5 using a container handling carrier 300. The third segment 24 of the transfer track grid 5 extends below the transfer column of the storage grid 104 and connects to the first segment 9 of the transfer track grid, allowing the container transfer carrier to move the storage container to the item pickup area. The second exemplary embodiment of the storage system includes, as shown in the figure... Figures 4 to 7 The storage system described in the text includes an item transport station 8 (not shown), which has a second segment 10 of the transfer track grid 5 connected to a first segment 9 of the transfer track grid 5 to allow integrated vehicles to move from the item pickup area 7 to the item transport station 8.
[0190] The container handling vehicle is characterized by wheel assemblies 32a, 32b that allow the vehicle to move in two vertical directions on the transfer track grid 5, and includes a storage container rack 38 for receiving storage containers lowered by the container handling vehicle 300 via the transfer column. In the exemplary container transfer vehicle 23, the container rack 38 has an open top 17 and four side walls 14. However, alternative container racks are conceivable. The requirement for the container rack is that during movement on the grid, the container rack can hold the storage containers in a stable position on the container transfer vehicle, and the container rack can receive the storage containers from above and provide top-side access to the items within the storage containers. Like the consolidation vehicle 6, the container transfer vehicle 23 has a maximum horizontal perimeter that adapts to a horizontal area defined by the grid cells 122' of the transfer track grid 5. This allows for a compact arrangement of multiple adjacent container transfer vehicles 23 and consolidation vehicles 6 at the item pickup area 7. This compact arrangement ensures that the distance the robotic pickup arm 11 must travel to pick up items from storage containers arranged on the container transfer carrier 23 and transfer them to the integration carrier 6 is as short as possible. By using the container transfer carrier to move the storage containers to the item pickup area, and... Figures 4 to 7 Compared to the storage system in the past, it provides more flexible positioning of the item pickup area.
[0191] Depend on Figures 12 to 14 The integration operations performed on the exemplary storage system in the example may include the above-mentioned operations targeting Figures 4 to 7 The exemplary storage system described in the figure includes the steps preceding these steps: retrieving a first storage container 106 having a first item 21 from storage grid 104, accommodating the first storage container on a first container transfer carrier 23 and positioning the first container transfer carrier 23 at a first segment 9 of transfer track grid 5; and optionally retrieving a second storage container 106 having a second item 21 from storage grid 104 and accommodating the second storage container on the second container transfer carrier 23 and positioning the second container transfer carrier 23 at a first segment 9 of transfer track grid 5.
[0192] Apart from the item pickup area 7, where items can be picked up by the automated robotic pickup arm 11, Figures 12 to 14 The exemplary storage system in the example is further characterized by having a manual pick-up / storage station for handling items that are not suitable for pickup by the robotic pick-up arm 11. If the order to be consolidated includes such unsuitable items, the consolidation vehicles 6, 6', 6" can be positioned at the manual pick-up / storage station to receive the items from the operator, for example, before moving to the conveyor station 8 or to the item pick-up area 7 to receive additional items to be consolidated.
[0193] The exemplary storage system is characterized by a single storage grid structure 104. However, the invention is also highly advantageous in similar storage systems characterized by at least two separate storage grid structures. In such a storage system, items stored in different storage grid structures can be easily integrated. For example, referring to the integration operation described above, a first storage container can be retrieved from a first storage grid structure, and a second storage container can be retrieved from a second storage grid structure.
[0194] In a further embodiment of the storage system of the present invention, the transfer track grid is arranged such that packages / items from at least one prior art or third-party storage system can be transferred to an integration vehicle for integration and / or packaging / processing at the packaging / processing component 12.
