Description

Technical Field

[0001] The present invention relates to a workstation for use with a storage and retrieval system for handling storage containers stored in different temperature and / or gas environments, and also to a storage and retrieval system and a method for retrieving a storage container (106) from the storage and retrieval system. Background Technology

[0002] Figure 1 A prior art automated storage and retrieval system 1 with a frame structure 100 is disclosed, and Figure 2 , Figure 3 and Figure 4 Three different prior art container handling devices 200, 300, and 400 suitable for operation on such a system 1 are disclosed.

[0003] The frame structure 100 includes upright members 102 and storage volumes comprising storage rows 105 arranged between the upright members 102. In these storage rows 105, storage containers 106 (also referred to as containers) are stacked one on top of another to form a stack 107. The members 102 can typically be made of metal, such as extruded aluminum profiles.

[0004] The frame structure 100 of the automated storage and retrieval system 1 includes a track system 108 arranged across the top of the frame structure 100, through which multiple container handling vehicles 200, 300, and 400 can operate to lift storage containers 106 from and lower storage containers 106 into storage columns 105, and also transport storage containers 106 above storage columns 105. The track system 108 includes a first set of parallel tracks 110 and a second set of parallel tracks 111. The first set of parallel tracks is arranged to guide the container handling vehicles 200, 300, and 400 across the top of the frame structure 100 in a first direction X. The second set of parallel tracks is arranged perpendicular to the first set of tracks 110 to guide the container handling vehicles 200, 300, and 400 in a second direction Y, perpendicular to the first direction X. Containers 106 stored in columns 105 are accessed by the container handling vehicles 200, 300, and 400 through access openings 112 in the track system 108. Container handling vehicles 200, 300, and 400 can move laterally above storage column 105, that is, laterally in a plane parallel to the horizontal XY plane.

[0005] The upright members 102 of the frame structure 100 can be used to guide the container 106 during the lifting of the container 106 from the column 105 and the lowering of the container 106 into the column. The stack 107 of the container 106 is typically self-supporting.

[0006] Each prior art container handling device 200, 300, 400 includes a handling device body / vehicle body 201, 301, 401 and a first set of wheels and a second set of wheels 202a, 202b, 302a, 302b, 402a, 402b, which enable the container handling device 200, 300, 400 to move laterally in the X and Y directions, respectively. Figure 2 , Figure 3 and Figure 4 In each group, two wheels are fully visible. The first group of wheels 202a, 302a, and 402a are arranged to engage with two adjacent tracks in the first group of tracks 110, and the second group of wheels 202b, 302b, and 402b are arranged to engage with two adjacent tracks in the second group of tracks 111. At least one group of wheels 202a, 202b, 302a, 302b, 402a, and 402b can be raised and lowered, such that the first group of wheels 202a, 302a, and 402a and / or the second group of wheels 202b, 302b, and 402b can engage with the corresponding track group 110, 111 at any given time.

[0007] Each prior art container handling device 200, 300, 400 also includes lifting devices 303, 403 for vertically transporting the container 106, such as lifting the container 106 from the storage column 105 and lowering the container 106 into the storage column. The lifting devices 303, 403 include one or more clamping / engaging devices 404 adapted to engage the container 106, and these clamping / engaging devices 404 can be lowered from the vehicle 200, 300, 400 such that the position of the clamping / engaging device 404 relative to the vehicle 200, 300, 400 can be adjusted in a third direction Z orthogonal to the first direction X and the second direction Y. Figure 4 The clamping device 404 of the container handling device / vehicle 400, which is in the form of multiple claws, is shown. The lifting device of the container handling device 200 is located inside the vehicle body 201 and is therefore not shown.

[0008] Conventionally, and also for the purposes of this application, Z=1 denotes the uppermost layer that can be used in the container below tracks 110 and 111, i.e., the layer immediately below track system 108; Z=2 denotes the second layer below track system 108; Z=3 denotes the third layer, and so on. Figure 1 In the exemplary prior art disclosed, Z=8 identifies the bottommost layer of the container. Similarly, X=1…n and Y=1…n identify the position of each storage column 105 in the horizontal plane. Therefore, as an example, and using… Figure 1 The Cartesian coordinate system X, Y, Z shown can be said to be in Figure 1The container labeled 106 occupies storage positions X=17, Y=1, Z=6. It can be said that container handling devices 200, 300, and 400 move within layer Z=0, and each storage column 105 can be identified by its X and Y coordinates. Therefore, Figure 1 The container shown extending above the orbital system 108 is also arranged in the layer at Z=0.

[0009] The storage volume 104 of the frame structure 100 is generally referred to as a storage grid, and the possible storage locations within the grid are referred to as storage cells. Each storage column can be identified by its position in the X and Y directions, and each storage cell can be identified by its container number in the X, Y, and Z directions.

[0010] Each prior art container handling device 200, 300, 400 includes a storage compartment or storage space for receiving and loading container 106 when transporting container 106 across the track system 108. The storage space may include cavities arranged inside the vehicle body 201, 301, 401, such as… Figure 2 and Figure 4 The contents of these applications, as shown in, for example, WO 2015 / 193278 A1 and WO 2019 / 206487 A1, are incorporated herein by reference.

[0011] Figure 3 An alternative configuration of a container handling device / vehicle 300 with a cantilever structure is shown. Such a vehicle is described in detail, for example, in NO 317366, the contents of which are also incorporated herein by reference.

[0012] Figure 2 The occupied area of ​​the central cavity vehicle 200 shown may cover an area in the X and Y directions with dimensions approximately equal to the lateral extent of the storage column 105, as described, for example, in WO 2015 / 193278 A1, the contents of which are incorporated herein by reference. The term “lateral” as used herein may mean “horizontal”.

[0013] Alternatively, the area occupied by the cavity container handling device / vehicle 400 may be larger than the lateral area defined by the storage column 105, such as Figure 1 and Figure 4 As shown, for example, in WO 2014 / 090684 A1 or WO 2019 / 206487 A1.

[0014] Track system 108 typically includes tracks with grooves in which the wheels of a vehicle travel. Alternatively, the tracks may include upwardly projecting elements, where the wheels of the vehicle include flanges to prevent derailment. These grooves and upwardly projecting elements are collectively referred to as guide rails. Each track may include one guide rail, or each track 110, 111 may include two parallel guide rails. In other track systems 108, each track in one direction (e.g., the X direction) may include one guide rail, while each track in another perpendicular direction (e.g., the Y direction) may include two guide rails. Each track 110, 111 may also include two guide rail members fastened together, each guide rail member providing one of the pair of guide rails provided by each track.

[0015] WO 2018 / 146304 A1 (the contents of which are incorporated herein by reference) shows a typical configuration of a track system 108, which includes tracks and parallel guide rails in both the X and Y directions.

[0016] In the frame structure 100, most columns are storage columns 105, that is, columns 105 are stored in the container 106 in the form of a stack 107. However, some columns may serve other purposes. Figure 1 In this context, columns 119 and 120 are dedicated columns used by container handling devices 200, 300, and 400 to unload and / or pick up containers 106, enabling the containers to be transported to a retrieval station (not shown), where containers 106 can be accessed from outside the frame structure 100, or moved in or out of the frame structure 100. In the art, such locations are commonly referred to as “ports,” and the columns containing the ports may be referred to as “port columns” 119 and 120. Transport to the retrieval station can be carried out in any direction (i.e., horizontal, inclined, and / or vertical). For example, containers 106 can be placed in random or dedicated columns 105 within the frame structure 100, and then picked up by any container handling device and transported to port columns 119 and 120 for further transport to the retrieval station. Transport from the port to the retrieval station may require movement along various different directions via means such as transport vehicles, trolleys, or other transport routes. Note that the term "inclined" refers to the transport of container 106 having a general transport orientation in some direction between horizontal and vertical.

[0017] exist Figure 1In the first port column 119, for example, it can be an unloading port column, at which container handling devices 200, 300, and 400 can unload containers 106 to be transported to the storage or transfer station, and the second port column 120 can be a dedicated pick-up port column, at which container handling devices 200, 300, and 400 can pick up containers 106 that have been transported from the storage or transfer station.

[0018] The storage and retrieval station is typically a pick-up or preparation station where product items are removed from or positioned into container 106. At the pick-up or preparation station, container 106 is not typically removed from the automated storage and retrieval system 1, but rather returned to the frame structure 100 after retrieval. The port can also be used to transfer containers to another storage facility (e.g., to another frame structure or another automated storage and retrieval system), to a transport vehicle (e.g., a train or truck), or to a production facility.

[0019] A conveyor system consisting of multiple conveyors is typically used to transport containers between port columns 119, 120 and the access station.

[0020] If port columns 119, 120 and access stations are located at different horizontal levels, the conveying system may include a lifting device with vertical components for vertically conveying container 106 between port columns 119, 120 and access stations.

[0021] The transport system can be arranged to transfer container 106 between different frame structures, such as those described in WO 2014 / 075937 A1, the contents of which are incorporated herein by reference.

[0022] When you need to access the stored Figure 1When a container 106 is in one of the disclosed storage columns 105, one of the container handling devices 200, 300, and 400 is instructed to remove the target container 106 from its location and transport it to the unloading port column 119. This operation involves moving the container handling devices 200, 300, and 400 to a position above the storage column 105 where the target container 106 is located, removing the container 106 from the storage column 105 using the lifting mechanism of the container handling devices 200, 300, and 400, and transporting the container 106 to the unloading port column 119. If the target container 106 is located deep within the stack 107, i.e., one or more other containers 106 are positioned above the target container 106, the operation also involves temporarily moving the container positioned above before lifting the target 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 device subsequently used to transport the target container to the unloading port column 119, or using one or more other cooperating container handling devices. Alternatively or additionally, the automated storage and retrieval system 1 may have a container handling device 200, 300, 400 specifically designed for the task of temporarily removing container 106 from storage column 105. After the target container 106 has been removed from storage column 105, the temporarily removed container 106 can be repositioned back into its original storage column 105. However, the removed container 106 can alternatively be repositioned to another storage column 105.

[0023] When container 106 is to be stored in one of the multiple columns 105, one of the container handling devices 200, 300, and 400 is instructed to pick up container 106 from pick-up port column 120 and transport the container to a position above the storage column 105 in which the container is to be stored. After any container 106 located at or above the target position within the stack 107 has been removed, the container handling devices 200, 300, and 400 position the container 106 in the desired location. The removed container 106 can then be lowered back into the storage column 105 or repositioned to another storage column 105.

[0024] In order to monitor and control the automated storage and retrieval system 1, such as monitoring and controlling the position of each container 106 within the frame structure 100, the contents of each container 106, and the movement of the container handling devices 200, 300, 400, so that the required container 106 can be delivered to the required location at the required time without the container handling devices 200, 300, 400 colliding with each other, the automated storage and retrieval system 1 includes a control system 600, which is typically computerized and typically includes a database for keeping track of the containers 106.

[0025] Automated storage and retrieval systems, as described above, are typically configured to operate in areas with ambient temperatures (e.g., approximately 20°C). However, the optimal storage temperature may differ for certain types of products. For example, food may need to be stored at refrigerated temperatures (typically between 1°C and 4°C) or frozen temperatures (typically below -18°C or below -20°C).

[0026] In addition, there may be situations where the automated storage and retrieval system is surrounded by an atmosphere different from the ambient atmosphere, for example, in order to reduce the risk of fire by lowering the oxygen concentration in the ambient atmosphere.

[0027] Automated storage and retrieval systems with different temperature zones and controllable temperature are known. For example, WO2019 / 001816 A1 describes an automated storage and retrieval system with different temperature zones, wherein storage containers are transported between a frozen zone and an ambient temperature zone via an elevator. In the ambient temperature zone, the storage containers can be handled by an operator at a workstation. The workstation is configured such that a storage container is inserted from one side of the workstation, while another container is received from the other side.

[0028] The existing system has at least the following disadvantages: the workstation must be placed on top of the system, which increases the time required to deliver or retrieve goods from the end user.

[0029] Another example of an automated storage and retrieval system with different temperature zones is described in WO 2021 / 175872 A1, in which the system includes a normal temperature grid zone and a cooling grid zone. Each grid zone includes a passageway accommodating one or more workstations.

[0030] The existing system has at least the following drawbacks: it cannot efficiently transfer storage containers from one temperature zone to a workstation located in another temperature zone without facing temperature and / or gas-related issues.

[0031] The object of the present invention is to provide a workstation, storage and retrieval system, and a method for operating such a system, which solves or at least mitigates one of the above-mentioned problems. Summary of the Invention

[0032] This summary is provided to introduce a series of concepts that will be further described herein in a simplified form. This summary is not intended to identify key or essential features of the invention.

[0033] The invention is set forth and characterized in the independent claims, while the dependent claims describe other preferred / optional features. Advantageously, a workstation, system, and method are provided in which a container handling vehicle can remain in the same environment during the retrieval / transportation of storage containers.

[0034] In a first aspect, the present invention relates to a workstation as defined in any of the appended claims and / or a workstation as described with reference to the second aspect described below.

[0035] In a second aspect, the present invention relates to a storage and retrieval system for handling storage containers stored in different temperature and / or gas environments, hereinafter referred to as a storage system. This storage system may be an automated storage and retrieval system. Such a storage system is described below, in the appended clauses, and in the appended claims.

[0036] The storage system includes: a first space at a first temperature and / or a first atmosphere; a second space at a second temperature and / or a second atmosphere, different from the first temperature and / or atmosphere; a workstation arranged in the second space for handling storage containers by human and / or robotic operators; and an insulating barrier that thermally isolates the first space from the second space and / or prevents or at least reduces gas leakage between the first space and the second space. The barrier can be any structure separating the first and second spaces and can include straight walls and / or pipes / rows. Furthermore, the barrier can include common wall insulation materials such as polystyrene foam, mineral wool, and / or polyurethane. The barrier can be a wall of the enclosure structure for the first space.

[0037] When using thermal insulation barriers to prevent or at least reduce heat leakage between the first and second spaces, the first temperature may be, for example, below 5°C (i.e., refrigeration temperature) or below -16°C (i.e., freezing temperature). The second temperature may be, for example, above 15°C (i.e., room temperature).

[0038] The barrier may include openings arranged adjacent to workstations, wherein the size of the openings allows storage containers to pass through, or, in the case of storage containers of different heights, allows the tallest storage container to pass through. The openings are preferably closable.

[0039] In addition, the first space includes: a first horizontal track system; a first storage volume arranged below the first horizontal track system for storing storage containers in a vertically stacked manner; a first pick-up and delivery volume arranged below the first horizontal track system for retrieving storage containers from workstations / delivering storage containers to workstations via grid openings within the first track system; and a first container handling vehicle configured to lift and transport the storage containers along the first horizontal track system.

[0040] Similarly, the second space includes: a second horizontal track system; a second storage volume arranged below the second horizontal track system for storing storage containers in a vertically stacked manner; a second pick-up and delivery volume arranged below the second horizontal track system for retrieving / delivering storage containers from / to workstations via grid openings within the second track system; and a second container handling vehicle configured to lift and transport the storage containers along the second horizontal track system.

[0041] The first pick-and-place and transport volume and the second pick-and-place and transport volume may include storage columns that are empty except during transport to / from the workstation.

[0042] The grid openings of these pick-and-place and transport volumes are preferably located directly above or near the entry point of the container into the access port.

[0043] The workstation includes a first access port and a second access port. The first access port is configured to allow an operator to remove / transfer a storage container from / to a first storage volume via an opening. The second access port is configured to allow an operator to remove / transfer a storage container from / to a second storage volume. The term "remove" in this document actually means allowing an operator to receive and remove a storage container from both the first and second access ports.

[0044] Therefore, this storage system allows operators to remove / insert storage containers from storage volumes located in different temperature and / or gas environments via the same workstation. If the first and second spaces have different temperatures, the storage system ensures that temperature variations have minimal impact on the container handling vehicle in operation, thus minimizing the risk of temperature-related problems such as condensation and / or freezing of electronic components due to moisture intrusion.

[0045] In one exemplary configuration of the invention, the first access port may include a movable closure configured to open and close the first access port toward the first storage volume. Alternatively or further, the second access port may include a movable closure configured to open and close the second access port toward the second storage volume.

[0046] In another exemplary configuration of the invention, the internal volume of the workstation may surround a first transport channel for guiding a storage container between a first space and a first access port. Furthermore, the workstation may surround a second transport channel for guiding a storage container between a second space and a second access port. For example, the first and second transport channels may be formed as pipes and may contain one or more insulating materials.

[0047] In another exemplary configuration of the invention, the workstation may include a first container transport mechanism for horizontally transporting a storage container between a first pick-and-place and transport volume and a first access port. The workstation may also, or alternatively, include a second container transport mechanism for horizontally transporting a storage container between a second pick-and-place and transport volume and a second access port.

[0048] At least a portion of the first container transport mechanism may be arranged within an opening in the barrier or enclosure wall.

[0049] At least one of the first and second container transport mechanisms may further include a container holding device for supporting the storage container, and a motorized rotating device rotatably connected to the container holding device. The rotatable connection may be achieved, for example, by an arm extending as a horizontal member between the rotating device and the holding device. Preferably, the transport channel includes at least two or three such arms, each end of which is fixed to the container holding device.

[0050] In addition, the workstation's enclosure surrounding the transport channel can also enclose the openings to avoid or reduce heat and / or gas leakage between the first and second spaces.

[0051] Alternatively or additionally, the barrier separating the first space and the second space may include a movable closure configured to open and close the opening. Such a movable closure may replace or supplement any movable closure of the first access port.

[0052] For the workstation enclosure described above, the movable closure ensures that any heat and / or gas leakage between the first and second spaces is reduced or prevented. However, it should be noted that other methods of preventing / reducing such heat and / or gas leakage are conceivable. For example, leakage prevention / reduction can be achieved by placing any obstructing objects (such as one or more storage containers) within the transport passageway.

[0053] In another exemplary configuration of the invention, at least the portion of the first access port forming a transport path for the storage container from the first space may include insulating material to reduce atmospheric exposure within the first space to atmospheric exposure within the second space. Examples of insulating materials are polystyrene foam, mineral wool, and / or polyurethane.

[0054] In another exemplary configuration of the invention, the first access port and the second access port may be horizontally spaced apart by a certain width, which ensures that when an adult operator stands at the center position between the first access port and the second access port, both the storage container in the position within the first access port and the storage container in the position within the second access port are within the operator's arm length.

[0055] In another exemplary configuration of the invention, the workstation may include a control system with a graphical user interface for registering the removal / transfer of items from the workstation to a workstation storage container via a first access port and a second access port. The control system may be arranged between the access ports.

[0056] In another exemplary configuration of the invention, at least some of the vertical stacks of the second storage volume can be supported on an elevated second bottom, which is vertically raised relative to the bottom of the supporting workstation.

[0057] In another exemplary configuration of the invention, the workstation may be arranged between the first storage volume and the second storage volume relative to a horizontal plane (i.e., relative to a plane parallel to the plane of the track system).

[0058] In another exemplary configuration of the invention, at least some (e.g., all) of the vertical stacks of the first storage volume units and the workstation are supported on the same bottom. Furthermore, the vertical stacks of the second storage volume units may also be supported on the same bottom.

[0059] In another exemplary configuration of the invention, the first horizontal track system and the second horizontal track system can be vertically aligned.

[0060] In another exemplary configuration of the invention, the tracks of the first and second horizontal track systems oriented toward the workstation can be horizontally aligned, thereby allowing the first and second access ports of the workstation to be aligned with each other along a line perpendicular to the two storage volumes.

[0061] In another exemplary configuration of the invention, the workstation may be arranged below the first storage volume of the first space and optionally below at least a portion of the second storage volume.

[0062] In another exemplary configuration of the invention, the thermal barrier may further include a conduit configured to guide a storage container between a first storage volume and a workstation (preferably in a vertical direction) using a first container transport vehicle, wherein an opening in the barrier is located in the conduit and vertically aligned with the workstation. The conduit may be thermally insulated by using one or more thermal insulation materials (such as those mentioned above).

[0063] The conduit may also include a second opening, the size and location of which allow a second container handling vehicle operating on a second horizontal track system to place storage containers into the conduit. The conduit may also include a second movable closure configured to open and close the second opening.

[0064] In another exemplary configuration of the invention, the second space may include a plurality of second storage volumes and a plurality of workstations. Each workstation may be arranged below at least a portion of each second storage volume. Furthermore, the second storage volumes may be arranged below the first storage volume.

[0065] In this exemplary configuration, the barrier may include a plurality of conduits configured to guide the storage container between the first storage volume and the workstation, wherein each conduit may contain one or more insulating materials.

[0066] In a third aspect, the present invention relates to a method for removing a storage container from a storage and retrieval system, such as the storage and retrieval system described above and / or the storage and retrieval system as defined in the appended terms and / or claims.

[0067] The method may include the following steps: - Use the first container handling vehicle to remove the storage container from the top of the vertical stack within the first storage volume; - Transport the storage container along the first horizontal track system to a position above the first pick-up and delivery volume section; - Lower the storage container (preferably vertically) to a position adjacent to the opening and aligned (e.g., vertically aligned) with the first access port; - The storage container is positioned at the first access port via an opening; and - Retrieve the storage container from the first access port.

[0068] In an exemplary process of the present invention, the method may include the following steps: - Use a second container handling vehicle to remove the storage containers from the top of the vertical stack within the second storage volume; - Transport the storage container along the second horizontal track system to a position above the second pick-up and delivery volume section; - Lower the storage container (preferably vertically) to a position aligned with the second access port; - Arrange the storage container at the second access port; and - Retrieve the storage container from the second access port.

[0069] In another exemplary process of the invention, after the storage container is lowered to alignment with the first access port, the method may include the step of transporting the storage container via an opening to an operator-accessible location within the first access port using a first transport mechanism (e.g., a conveyor belt or rotary container handling device as described above). This first transport mechanism may also include thermal insulation material to further reduce any heat leakage between the first and second spaces.

[0070] A similar process can be performed to transport the storage container to an operator-accessible location within the second access port using a second transport mechanism.

[0071] In another exemplary process of the invention, the operator may remove items such as tote bags from the storage container after the storage container has been lowered and place the items on a trolley located near the workstation, or if there are multiple workstations, a trolley may be placed next to each workstation.

[0072] In another exemplary method of the present invention, the movable closure of the first access port and / or the thermal barrier is opened only before the storage container is removed from the first access port, in order to reduce or prevent heat leakage and / or gas leakage.

[0073] In a specific example where the first and second spaces respectively have a frozen environment and a room temperature environment, the storage containers can be transported downwards along the port column where no storage containers are stacked. At the bottom of the cooled space, and at a position flush with the workstation, the storage containers are transported through the opening and into the workstation at room temperature. Using this method, the risk of condensation of electronic components, such as those forming part of the lifting mechanism of the container transport vehicle, is significantly reduced in the frozen space. Furthermore, this risk is further reduced or even eliminated by adding movable closures to the first access port and / or opening. Attached Figure Description

Detailed Implementation

[0083] In general, a workstation (10) is provided for use with a storage and retrieval system (1) for handling storage containers (106) stored in a first storage volume (104) and a second storage volume (104') with different temperature environments. The workstation includes a first access port (11) and a second access port (12), the first access port being configured to allow an operator (4) to retrieve the storage container (106) from the first storage volume (104) via an opening (13) in a thermal barrier, and the second access port being configured to allow the operator (4) to retrieve the storage container (106) from the second storage volume (104'). A storage and retrieval system and a method for retrieving the storage container (106) from the storage and retrieval system (1) are also provided.

[0084] In the following description, embodiments of the invention will be discussed in more detail by way of example only and 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, although some features are described only with respect to the automatic storage and retrieval system 1, it is clear that they are also applicable to the related methods, and vice versa.

[0085] In the following description, embodiments of the invention will be discussed in more detail by way of example only and 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, although some features are described only with respect to the automated storage and retrieval system 1 and the container handling and transport vehicle 10, it is clear that they are also applicable to the related methods, and vice versa.

[0086] Figure 5 and Figure 6 A first embodiment of an automated storage and retrieval system 1 is shown, comprising a first space 2 and a second space 3 separated by a wall 6. The wall 6 has one or more openings 13, the size of which allows a storage container 106 (hereinafter referred to as a "box") to pass through... Figure 7 ).

[0087] Each of spaces 2 and 3 includes: storage volumes 104 and 104' of stacks 107 containing containers 106; track systems 108' and 108' arranged above the storage volumes 104 and 104'; and multiple remotely operated container handling vehicles 300 running on the track systems 108 and 108'.

[0088] Orbit systems 108 and 108' can be connected with Figure 1 The track system shown (see the "Background Art" section) is similar or identical, that is, it includes a first set of parallel tracks 110 and a second set of parallel tracks 111. The first set of parallel tracks is arranged to guide the container transport vehicle 300 to move along a first direction X, and the second set of parallel tracks is arranged perpendicular to the first set of tracks 110 to guide the container transport vehicle 300 to move along a second direction Y, which is perpendicular to the first direction X.

[0089] The frame structures 100 and 100', including the track systems 108 and 108' and the storage volumes 104 and 104', can be combined with the above. Figure 1 The existing frame structure 100 is constructed in a similar or identical manner. Therefore, in addition to the track systems 108, 108', each frame structure 100, 100' may also include a plurality of upright members 102 forming storage columns 105 and port columns 119, 120.

[0090] The container handling vehicle 300 can access the topmost box 106 of each stack 107 through the access openings 112 in the track system 108, 108'.

[0091] Tracks 110 and 111 are preferably dual-track tracks to enable more efficient / dense traffic on track system 108.

[0092] As in Figure 5As best seen in A, the second space 3 also includes one or more workstations 10 arranged on the floor 20, wherein the workstations 10 are configured to receive boxes 106 from storage volumes 104 and 104' and to transport boxes to the storage volumes.

[0093] Workstation 10 (or each workstation 10 in the case of multiple workstations 10) may include: a first access port 11 for receiving box 106 from / transferring box 106 to the first storage volume 104 in the first space 2; a second access port 12 for receiving box 106 from / transferring box 106 to the second storage volume 104' in the second space 3; and a control system 15 having a graphical user interface (GUI) for allowing operator 4 to monitor and control the storage / retrieval of box 106 from storage volumes 104, 104'. Workstation 10 may also be designed with an ergonomic operator space 16 arranged between the first access port 11 and the second access port 12, allowing operator 4 to easily remove box 106 from / insert box 106 into the corresponding access port 11, 12 with minimal movement. One possible workstation design could be a square U-shaped design, with access ports 11 and 12 arranged horizontally on both sides of the workstation and the GUI placed between these two access ports.

[0094] In order to receive the container 106 from the first storage volume 104 and to transport the container to the first storage volume, the first access port 11 is positioned adjacent to the opening 13 to allow the container 106 to be transported through the opening.

[0095] Figure 7 A workstation 10 is shown arranged between a first storage volume 104 and a second storage volume 104', wherein a first section 10' retrieves / transports a box 106 from the first storage volume 104, and a second section 10'' retrieves / transports a box 106 from the second storage volume 104'. Each section 10', 10'' includes a workstation cover 17 surrounding a box transport mechanism 50 for transporting the box 106 from access ports 11, 12 to port rows 119, 119' or from port row to port row. The box transport mechanism is in the form of a rotating device / turntable 50, such as the turntable of the prior art described in patent publication WO 2012 / 026824 A1, the contents of which are incorporated herein by reference.

[0096] Specifically, the turntable 50 may include a plurality of box holding devices 51, such as three box holding devices, wherein each holding device 51 is configured to hold a box 106. The holding device 51 may be, for example, an open tray. Each holding device 51 may be rotatably fixed to the outer end of an arm 52, wherein the other end of each arm is fixed to a common motorized rotating device 53. The turntable 50 may also include a turntable frame 54 that supports the rotating device 53, the arm 52 and the holding devices 51 at a desired height within sections 10, 10' of the workstation 10.

[0097] By using this turntable 50, the arm 52 can be rotated using the motorized rotating device 53 to position the empty holding device 51 into the "discharge" port rows 119, 119', thereby removing the box 106 from the storage volumes 104, 104'. The container transport vehicle 300 can lower the box 106 onto the holding device 51, and then use the rotating device 53 to rotate the holding device 51 together with the box 106, thereby allowing the operator 4 to access the box 106 via the access ports 11, 12.

[0098] Alone or simultaneously, another holding device 51 (with a box 106 containing items to be stored) located on another arm 52 of turntable 50 may be arranged in “pick-up” port row 120 for pickup by container transport vehicle 300.

[0099] In order to allow the box 106 to be removed / transported into the first storage volume 104, Figure 7 In the solution shown, the first segment 10' is inserted into the opening 13 of the wall 6, wherein the height and width of the opening 13 above the floor 20 correspond to the height and width of the workstation 17, thereby ensuring that heat leakage and / or gas leakage between the first space 2 and the second space 3 is prevented / reduced during operation.

[0100] Generally, the container transport mechanism 50 can be any mechanism that allows the container 106 to move between the storage volumes 104, 104' and the access ports 11, 12 of the corresponding sections 10', 10'', such as a conveyor belt and / or a linear actuator.

[0101] Furthermore, preventing / reducing heat leakage and / or gas leakage between the first space 2 and the second space 3 during the transport of such containers can be achieved by arranging a movable closure (such as a hinged door or a vertically sliding plate) in front of the opening 13 that can be closed and opened.

[0102] The desired leak-proof effect can also be achieved by installing a closing / opening mechanism (e.g., a cover that can be operated by operator 4 from operator space 16 and / or a cover that is automatically controlled by control system 15) on the first access port 11.

[0103] Figure 5 Also shown is a trolley 40 arranged adjacent to workstation 10 for storing and transporting multiple conveyor boxes 45 to facilitate the removal of items stored in storage boxes 106 from workstation 10 and the transport of items stored in storage boxes to workstation 10.

[0104] In order to use Figure 5 The system of the first embodiment described herein stores items in the storage volume 104 of the first space 2, and can perform the following steps: a. Using a wheeled trolley 40, one or more conveyor boxes 45 containing items to be stored are brought to the workstation. b. Place the empty container 106 into the first access port 11 of the first section 10' of the workstation and onto the container transport mechanism 50. c. Pick up the required items from conveyor box 45 and arrange these items into box 106. d. The GUI of the control system 15 is used to confirm whether the transport of the box 106 from the first access port 10 to the pick-up column 120 is ready. e. Allocate a storage column 105 within storage space 104 to box 106. f. If applicable, remove the movable closure from opening 13. g. The box 106 is moved from the first access port 11 to the pick-up column 120, which forms part of the pick-up and transport volume, using the box transport mechanism 50, wherein the transport passes through the opening 13 in the wall 6. h. If applicable, return the movable closure to its initial position. i. Move the container transport vehicle 300 on the track system 108, so that the vehicle's lifting device 303 (see...) Figure 3 Positioned directly above pick column 120. j. Use lifting device 303 to lift box 106 above track system 108. k. Move the container handling vehicle 300 carrying box 106 along the track system 108, such that box 106 is positioned directly above the assigned storage column 105, and 1. Lower box 106 into storage column 105 via grid opening 112 to arrange box 106 on stack 107, or arrange box on floor 16 if storage column 105 is empty.

[0105] Steps a through d are typically performed by operator 10, while steps e through 1 are typically controlled by control systems 15 and 109, such as the control system of the container handling vehicle 109. If Figure 7If the turntable 50 shown is used as a box transport mechanism 50, then step g includes rotating the holding device 51 by using a motorized rotating device 53. Steps f and h can be omitted.

[0106] For steps d through h, a dedicated workstation control system 15 can be used. In this case, workstation 15 can send commands to the system's control system 109, which in turn instructs the container handling vehicle 300 to perform steps i through l.

[0107] Similarly, in order to retrieve the desired item from the storage volume 104, the following steps can be performed: a. Using the lifting device 303 of the container handling vehicle 300, the required box 106 is picked up from the stack 107 or floor 20 within the storage column 105. b. Move container transport vehicle 300 to a position where container 106 is directly above unloading column 119. c. Lower the container 106 into the unloading column 119 and onto the container transport mechanism 50, wherein the relevant portion of the container transport mechanism 50 is horizontally aligned with the unloading column 119 and vertically aligned with the opening 13. d. If applicable, remove the movable closure from opening 13. e. Using the box transport mechanism 50, the box 106 is moved through the opening 13 in the wall 6 to the first access port 11. f. Retrieve the required items from the container 106 via the first access port 11 and arrange these items into the conveyor box 45. g. If applicable, return the movable closure to its initial position, and h. Use a wheeled trolley 41 to carry the conveyor box 45 containing the required items away from the workstation.

[0108] During transport and retrieval, the same column can be used for both pick column 120 and unload column 119.

[0109] In addition to manipulating the movable closure (i.e., steps f and h for conveying and steps d and g for retrieving), the same process steps as described above can be used to perform the conveying to / retrieving from the second storage volume 104'.

[0110] like Figure 5 and Figure 6As shown, the second frame 100' of the second space 3 can be divided into a main body supported on the floor 20 and a raised section supported on the raised platform 32. The space between the raised platform 32 and the floor 20 can be used, for example, for the transport of machinery (such as pickup trucks) inside the storage facility and / or for transporting delivery boxes 45 using wheeled trolleys 40 and / or for arranging additional workstations 10 to further accelerate the transport / retrieval of boxes 106.

[0111] Figure 8 A second embodiment of the automatic storage and retrieval system 1 is shown. Regarding the first embodiment, system 1 includes a first space 2 and a second space 3 for a storage tank 106, wherein the first space 2 and the second space 3 may contain different environments / atmospheres, such as different temperatures and / or different gases.

[0112] The first space 2 includes a first frame 100 arranged on a raised platform 30. The first frame 100 includes a first storage volume 104 with stacks 107 having boxes 106, and a first track system 108 arranged on top of the first storage volume 104. The first space 2 also includes a plurality of container handling vehicles 300 running on the first track system 108.

[0113] The second space 3 of the storage system 1 in the second embodiment includes a plurality of second frames 100' arranged below the raised platform 30, wherein each second frame 100' includes a second storage volume 104' and a second track system 108' arranged on top of the second storage volume 104'. The second storage volume 104' accommodates stacked boxes 106.

[0114] Furthermore, the workstation 10 and the trolley 40, as described above with respect to the first embodiment, can be arranged adjacent to each of the second frames 100'.

[0115] Regarding the first embodiment, one or more second frames 100' may be divided into a main body supported on the floor 20 and an elevated portion supported on the raised platform 32, wherein the workstation 10 is arranged in the space formed by the elevated portion. One or more container handling vehicles 300 may operate on each second track system 108'.

[0116] Both the first frame 100 and the second frame 100' may also include upright members 102, wherein storage columns 105 or port columns 119, 120 are arranged in rows between the upright members 102, wherein each storage column 105 accommodates a stack 107 of boxes 106, while each port column 119, 120 does not accommodate a box 106.

[0117] Instead of the single vertical wall 6 shown in the first embodiment, the isolation between the first space 2 and the second space 3 in different thermal and / or gaseous environments is achieved by a more complex and fully enclosed structure 6 surrounding the first frame 100 and the vehicle 300 running on the first frame 100.

[0118] The enclosed structure 6 includes a surrounding vertical wall extending from the raised platform 30 to the ceiling or dedicated roof (not shown) of the warehouse, and a pipe 6' extending downward from the raised platform 30 to the floor 20 where the workstation 10 is located.

[0119] The conduit 6' has an opening 13 through which the box 106 can pass, and the first section 10' of the workstation 10 is positioned such that the box 106 can be moved between the position within the conduit 106' (which is typically an extension of one or more port columns 119, 120 of the first frame structure 100) and the first access port 11 using a box transport mechanism 50 (such as a turntable described above).

[0120] In order to use Figure 8 The system of the second embodiment described herein stores items in the storage volume 104 of the first space 2, and can perform the following steps: a. Using a wheeled trolley 40, one or more conveyor boxes 45 containing items to be stored are brought to a workstation. b. Place the empty container 106 into the first access port 11 of the first section 10' of the workstation and onto the container transport mechanism 50. c. Pick up the required items from conveyor box 45 and arrange these items into box 106. d. Confirm via the GUI of control system 15 whether the transport of container 106 from first access port 11 / first section 10' to pipe 6' is ready. e. Allocate a storage column 105 within storage space 104 to box 106. f. If applicable, remove the movable closure from the opening 13 in pipe 6'. g. The container 106 is moved from the first access port 11 into the pipe 6' using the container transport mechanism 50, wherein the transport passes through the opening 13 of the pipe 6'. h. If applicable, return the movable closure to its initial position. i. Move the container transport vehicle 300 on the track system 108, thereby enabling the vehicle's lifting device 303 (see Appendix) to move the container transport vehicle 300 on the track system 108. Figure 3 It is positioned directly above the pickup column 120 of the first storage volume section and directly above the pipe 6' arranged along the second storage volume section 104'. j. Using the lifting device 303, lift the box 106 along the pipe 6' and the pickup column 120 until the box 106 is above the track system 108. k. Move the container handling vehicle 300 carrying box 106 along the track system 108, such that box 106 is positioned directly above the assigned storage column 105, and 1. Lower box 106 into storage column 105 via grid opening 112 to arrange box 106 on stack 107, or arrange box on floor 16 if storage column 105 is empty.

[0121] In this embodiment, the pipe 6' and the pickup column 120 are arranged directly above each other to allow vertical box transport between the track system 108 and the opening 13.

[0122] Similarly, in order to retrieve the desired item from the first storage volume 104 of the system according to the second embodiment, the following steps can be performed: a. Using the lifting device 303 of the container handling vehicle 300, the required box 106 is picked up from the stack 107 or floor 20 within the storage column 105. b. Move the container handling vehicle 300 to a position where the container 106 is directly above the unloading column 119 and directly above the pipe 6' aligned with the unloading column 119. c. The container 106 is lowered onto the container transport mechanism 50 via the unloading column 119 and the pipe 6', wherein the relevant part of the container transport mechanism 50 is horizontally aligned with the pipe 6' and vertically aligned with the opening 13. d. If applicable, remove the movable closure from opening 13. e. Using the box transport mechanism 50, the box 106 is moved through the opening 13 in the wall 6 to the first access port 11. f. Retrieve the required items from the container 106 via the first access port 11 and arrange these items into the conveyor box 45. g. If applicable, return the movable closure to its initial position, and h. Use a wheeled trolley 41 to carry the conveyor box 45 containing the required items away from the workstation.

[0123] In the foregoing description, various aspects of the system and method according to the invention have been described with reference to illustrative embodiments.
