The present disclosure also relates to a method for securing two upright members (102a, 102b) of a frame structure (100).

Description

Technical Field

[0001] This disclosure relates primarily to a method for fixing two vertically aligned upright members. Background Technology

[0002] Figure 1 A prior art automated storage and retrieval system 1 with a frame structure 100 is disclosed, and Figure 2 , Figures 3a to 3b Three different prior art container handling vehicles 201, 301, and 401 suitable for operation on such 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 boxes) are stacked one on top of another to form a container stack 107. 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 301, 401 can operate to lift and lower storage containers 106 from storage columns 105 into the storage columns, and also transport storage containers 106 above the storage columns 105. The track system 108 includes: a first set of parallel tracks 110 arranged to guide the container handling vehicles 301, 401 across the top of the frame structure 100 in a first direction X; and a second set of parallel tracks 111 arranged perpendicular to the first set of tracks 110 to guide the container handling vehicles 301, 401 in a second direction Y perpendicular to the first direction X. Containers 106 stored in the columns 105 are accessed by the container handling vehicles 301, 401 through access openings 112 in the track system 108. Container handling vehicles 301 and 401 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 containers during the lifting of the storage containers from the column 105 and the lowering of the storage containers into the column. The stack 107 of the containers 106 is typically self-supporting.

[0006] Each prior art container handling vehicle 201, 301, 401 includes a body 201a, 301a, 401a, a first set of wheels 201b, 301b, 401b, and a second set of wheels 201c, 301c, 401c, which enable the container handling vehicle 201, 301, 401 to move laterally in the X and Y directions, respectively. Figures 2 to 3b In this configuration, two wheels in each group are fully visible. The first group of wheels 201b, 301b, and 401b are arranged to engage with two adjacent tracks in the first group of tracks 110, and the second group of wheels 201c, 301c, and 401c are arranged to engage with two adjacent tracks in the second group of tracks 111. At least one group of vehicles among these wheel sets 201b, 201c, 301b, 301c, 401b, and 401c can be raised and lowered, such that the first group of wheels 201b, 301b, and 401b and / or the second group of wheels 201c, 301c, and 401c can engage with the corresponding track set 110, 111 at any given time.

[0007] Each prior art container handling vehicle 201, 301, 401 also includes lifting devices 304, 404 (in... Figures 3a to 3b As can be seen in the image, the lifting device has lifting frame portions 304a, 404a for vertically transporting the storage container 106, for example, lifting the storage container 106 from the storage column 105 and lowering the storage container 106 into the storage column. The lifting devices 304, 404 include one or more gripping / engaging mechanisms adapted to engage with the storage container 106, and these gripping / engaging mechanisms can be lowered from the vehicles 201, 301, 401, such that they can be lowered in a third direction Z (e.g., in a direction orthogonal to the first direction X and the second direction Y) to the storage container 106. Figure 1 (As can be seen in the image) Adjust the position of the gripping / engaging mechanism relative to vehicles 201, 301, and 401. A portion of the gripping mechanism of container handling vehicles 301 and 401 is located within... Figure 3a and Figure 3b It is shown in the figure and indicated by reference numerals. Figure 2 In the container handling device 201, the gripping mechanism is located inside the vehicle body 201a.

[0008] Conventionally, and also for the purposes of this application, Z=1 denotes the uppermost layer below tracks 110 and 111 that can be used for storage containers, 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 herein, Z=8 identifies the bottommost layer of the storage 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 1The Cartesian coordinate system X, Y, Z shown can be said to be in Figure 1 The storage container labeled 106 occupies storage positions X=18, Y=1, Z=6. It can be said that container transport vehicles 201, 301, and 401 travel in the layer at Z=0, and each storage column 105 can be identified by its X and Y coordinates. Therefore, Figure 1 The storage container shown extending above the orbital system 108 is also referred to as being arranged in the layer at Z=0.

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

[0010] Each prior art container handling vehicle 201, 301, 401 includes a storage compartment or space for receiving and loading the storage container 106 during transport across the track system 108. The storage space may include cavities arranged inside the vehicle body 201a, such as… Figure 2 and Figure 3b The contents of these applications, as shown in, and described, for example, in WO2015 / 193278A1 and WO2019 / 206487A1, are incorporated herein by reference.

[0011] Figure 3a An alternative construction of a container handling vehicle 301 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 cavity container transport vehicle 201 shown can cover an area in the X and Y directions that is approximately equal in size to the lateral extent of the storage column 105, as described, for example, in WO2015 / 193278A1, 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 transport vehicle 401 can be larger than the lateral area defined by the storage column 105, such as... Figure 3b As shown in WO2014 / 090684A1 or WO2019 / 206487A1.

[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 may include two parallel guide rails; in other track systems 108, each track may include one guide rail in one direction and two guide rails in another perpendicular direction. The track system may also include a dual-guide rail in one of the X and Y directions and a single-guide rail in the other direction. A dual-guide rail may include two track members fastened together, each track member having one guide rail.

[0015] WO2018 / 146304A1 (the contents of which are incorporated herein by reference) shows a typical construction of an orbital system 108, which includes orbits and parallel guide rails in both the X and Y directions.

[0016] In the frame structure 100, most columns 105 are storage columns 105, that is, columns 105 in which storage containers 106 are stored in a stack 107. However, some columns 105 may serve other purposes. Figure 1 In this context, columns 119 and 120 are dedicated columns used by container handling vehicles 201, 301, and 401 to unload and / or pick up storage containers 106, enabling the storage containers to be transported to retrieval stations (not shown) where they 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 take place in any direction (i.e., horizontal, inclined, and / or vertical). For example, storage containers 106 can be placed in random or dedicated columns 105 within the frame structure 100, and then picked up by any container handling vehicle 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 in various directions via delivery vehicles, trolleys, or other transport routes. It should be noted that the term "inclined" refers to the transport of storage 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 a dedicated unloading port column, at which container handling vehicles 201, 301 can unload storage containers 106 to be transported to the storage station or transfer station, and the second port column 120 can be a dedicated pick-up port column, at which container handling vehicles 201, 301, 401 can pick up storage containers 106 that have been transported from the storage station or transfer station.

[0018] The storage and retrieval station is typically a pick-up station or a stocking station where product items are removed from or positioned into storage container 106. At the pick-up station or stocking station, storage container 106 is not typically removed from the automated storage and retrieval system 1; instead, it is returned to frame structure 100 after storage and retrieval. The port can also be used to transfer storage 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] Storage containers are typically transported between port lines 119 and 120 and the access station using a transport system that includes a transmitter.

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

[0021] The transfer system can be arranged to transfer storage container 106 between different frame structures, such as those described in WO2014 / 075937A1, the contents of which are incorporated herein by reference.

[0022] When you need to access the stored Figure 1When a storage container 106 is in one of the multiple columns 105 disclosed herein, one of the container handling vehicles 201, 301, and 401 is instructed to remove the target storage container 106 from its location and transport it to the unloading port column 119. This operation involves moving the container handling vehicles 201 and 301 to a position above the storage column 105 where the target storage container 106 is located, removing the storage container 106 from the storage column 105 using the lifting devices (not shown) of the container handling vehicles 201, 301, and 401, and transporting the storage container 106 to the unloading port column 119. If the target storage container 106 is located deep within the stack 107, i.e., one or more other storage containers 106 are located above the target storage container 106, the operation also involves temporarily moving the storage container located above it 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 vehicle subsequently used to transport the target storage container to unloading port column 119, or using one or more other cooperating container handling vehicles. Alternatively or additionally, the automated storage and retrieval system 1 may have container handling vehicles 201, 301, 401 specifically for the task of temporarily removing storage container 106 from storage column 105. After the target storage container 106 is removed from storage column 105, the temporarily removed storage container 106 can be repositioned back into the original storage column 105. However, the removed storage container 106 can alternatively be repositioned to another storage column 105.

[0023] When storage container 106 is to be stored in one of the multiple columns 105, one of the container handling vehicles 201, 301, and 401 is instructed to pick up storage container 106 from pick-up port column 120 and transport it to a position above the storage column 105 in which it will be stored. After removing storage container 106 from its target location within stack 107, container handling vehicles 201, 301, and 401 position storage container 106 in the desired location. The removed storage container 106 can then be lowered back into storage column 105 or repositioned to another storage column 105.

[0024] To monitor and control the automated storage and retrieval system 1, for example, to monitor and control the position of each storage container 106 within the frame structure 100, the contents of each storage container 106, and the movement of container transport vehicles 201, 301, and 401, so that the required storage container 106 can be delivered to the required location at the required time without the container transport vehicles 201, 301, and 401 colliding with each other, the automated storage and retrieval system 1 includes a control system 500 (in... Figure 1As shown in the figure, the control system is typically computerized and usually includes a database for keeping track of the storage container 106.

[0025] In accommodating conventional three-dimensional storage systems (such as Figure 1 In a building with a three-dimensional storage system (as shown), the goal is to make the best use of available space.

[0026] Furthermore, and as discussed above, the storage system's frame structure includes parallel upright members supporting rails with guide rails for the wheels of the container transport vehicle. The upright members also function to guide the vertical movement of the vehicle via a lifting frame section. Therefore, the upright members must be manufactured without dimensional deviations. In relevant cases, the upright members must remain aligned with each other during frame structure assembly and after the structure is put into use.

[0027] In view of the above, it is desirable to provide a solution to address or at least mitigate one or more of the aforementioned problems that are part of the prior art. Summary of the Invention

[0028] The summary of this invention is provided to introduce some concepts in a simplified form that will be further described herein. This summary is not intended to identify key or essential features of this disclosure.

[0029] This disclosure is set forth and characterized in the independent claims, while the dependent claims describe other optional features of this disclosure.

[0030] One aspect of this disclosure relates to a coupling device and connector assembly according to claim 9.

[0031] By providing the joining device and connector assembly as described above, a cost-effective solution that significantly increases the storage space of the system is achieved. Clearly, the increased storage space improves the overall economics of the storage system. Furthermore, no special training is required for workers assigned to the specific task of system installation. Installation can also be performed without the use of special tools.

[0032] Furthermore, and with the aid of the components disclosed herein, the joined and aligned upright member assemblies are straight and positioned at the correct distance relative to other upright member assemblies of the installed frame structure.

[0033] The proposed solution is compatible with existing designs of storage and retrieval systems, allowing existing systems to be retrofitted using the engagement devices and connector assemblies disclosed herein, and introducing engaged and aligned upright component assemblies, ultimately resulting in an increase in the effective height of the storage system.

[0034] Another aspect of this disclosure relates to a method for securing two upright members by means of a coupling device and a connector assembly. For the sake of brevity, the advantages discussed above in conjunction with the coupling device and connector assembly can also be associated with the corresponding method, and will not be discussed further here. It should be explained here that the order of the method steps in the method claims can be implemented in any given order.

[0035] In one aspect, the engagement device and connector assembly of this disclosure are used in the context of a frame structure including upright members, wherein the assembly is installed when the upright members are vertically oriented.

[0036] In a related aspect, the components of this disclosure are intended for use in the context of a storage volume comprising storage columns for storing stacks of cargo holding devices. These storage columns are arranged in rows between upright members.

[0037] In another aspect, the component is used in the context of a track system that spans and forms part of a frame structure. More specifically, the track system is supported by upright members joined and secured by the component. Here, multiple remotely operated vehicles travel on the track system and are used to lift and lower cargo holding devices from and into storage columns, and also to transport cargo holding devices above the storage columns. During this transport, the remotely operated vehicles move in a plane parallel to the horizontal plane.

[0038] In this context, the components disclosed herein are intended for use with various types of container handling vehicles, such as cantilever-based container handling vehicles or container handling vehicles having cavities arranged inside.

[0039] In one aspect, this component is used in the context of an SDG-based track system. Here, SDG stands for Single / Dual Grid. This design is implemented with a single-track guide along one axis and a dual-track guide along the other axis. Using a single track in one direction requires a storage unit between meeting robots.

[0040] In another aspect, the joining members and connector assemblies of this disclosure are intended for use in the context of DDG-based track systems. Here, DDG stands for dual / dual grid. This design is implemented with dual-track guides in all directions, allowing the robot to pass over each other in all directions.

[0041] In connection with the concept of this application, the term "container handling vehicle" as used in the "Background Art" section of this application is synonymous with the term "remotely operated vehicle" as used in the remainder of this application text, and defines an autonomous wheeled vehicle operating on a track system arranged across the top of a frame structure as part of an automated storage and retrieval system.

[0042] Similarly, the terms "storage container" and "storage box" used in the "Background Art" section of this application are synonymous with the term "cargo holding device" used in the remainder of this application and define containers for storing articles. In the relevant context, the cargo holding device of this application can be any of a box, suitcase, pallet, tray, or the like. Different types of cargo holding devices can be used in the same automated storage and retrieval system.

[0043] The relative terms “upper,” “lower,” “below,” “above,” “higher,” etc., should be understood in their usual sense and as shown in a Cartesian coordinate system. When referring to an orbital system, “upper” or “above” should be understood as a position (relative to another component) closer to the surface of the orbital system, while the terms “lower” or “below” should be understood, conversely, as a position (relative to another component) further away from the orbital system.

[0055] In the following, embodiments of the present disclosure 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 present disclosure to the subject matter depicted in the drawings.

[0056] The framework structure 100 of the automatic storage and retrieval system 1 is based on the above. Figures 1 to 3b The existing frame structure 100 described herein is constructed, namely, including a plurality of upright members 102, wherein the frame structure 100 further includes a first upper track system 108 in the X and Y directions.

[0057] The frame structure 100 also includes storage compartments arranged in the form of storage columns 105 between the members 102, wherein storage containers 106 can be stacked in the storage columns 105 in the form of stacks 107.

[0058] The frame structure 100 can have any size. Specifically, it should be understood that the frame structure can be larger than... Figure 1 The disclosed frame structure is wider and / or longer and / or deeper. For example, frame structure 100 may have a horizontal range of more than 700×700 columns and a storage depth of more than twelve containers.

[0059] Now refer to Figures 4 to 7 The various aspects of this disclosure will be discussed in more detail.

[0060] Figure 4 This is a cross-sectional view of upright members 102a and 102b for use with components of this disclosure. As can be seen, upright member 102a has four sides 62a-62d arranged in a rectangular manner. Outwardly facing slots 74a and 74b extend in the longitudinal direction of upright members 102a and 102b. In the illustrated embodiment, slots 74a and 74b are T-shaped.

[0061] These slots 74a and 74b are used to receive the first plate-shaped component of the assembly of this disclosure (such as in conjunction with...). Figure 5a (Shown and discussed). Also shown are portions of the outer walls 72a, 72b of the upright members 102a, 102b for being held between the first plate-like member and the second plate-like member. In this case, these portions 72a, 72b include a pair of ridges 77a, 77b for engaging with longitudinally extending grooves arranged on the sides of the first plate-like member.

[0062] As can be seen, the central portion of the upright member 102a is hollow. Each of the four corner portions 64a-64d of the upright member 102a is recessed. Each corner portion 64a-64b is associated with two mutually perpendicular flanges 66a-66b. These flanges 66a-66b serve as guides for a cargo holding device that is vertically transported by a remotely operated vehicle.

[0063] Figure 5a This is a perspective view showing a joining device according to an embodiment of the present disclosure, which is part of the joining device and connector assembly of the present disclosure. The joining device 20 is used to join a frame structure (100; such as a joint). Figure 7 (Shown and discussed) Two upright members aligned with each other. Further reference. Figure 1 The frame structure provides storage volume sections with storage columns for holding devices for storing goods. The track system of the frame structure is located above the upright members.

Figure 4 (as shown in the figure), and the upper portion 34 of the first plate-shaped member 30 is configured for insertion into a slot associated with the second upright member 102b.

[0065] The joining device 20 also includes a second plate-like member 40, wherein the lower portion 42 of the second plate-like member 40 is configured to abut against the first upright member (102a; for example in...). Figure 7 The outer wall shown in the figure Figure 4 (as shown in the diagram) a portion such that this portion of the outer wall is sandwiched between the lower portion 32 of the first plate-like member 30 and the lower portion 42 of the second plate-like member 40, and the upper portion 44 of the second plate-like member 40 is configured to abut the second upright member (102b; for example in Figure 7 A portion of the outer wall (shown in the figure) is sandwiched between the upper portion 34 of the first plate-shaped member 30 and the upper portion 44 of the second plate-shaped member 40.

[0066] The joining device 20 also includes a connecting device for connecting the first plate-shaped member 30 and the second plate-shaped member 40, such that the upright member ( Figure 7 102a and 102b are joined together to form the first set of joined upright members ( Figure 7 27 in the middle). The first set of upright members thus formed includes two upright members ( Figure 7 (102a and 102b in the text).

[0067] The connecting device for connecting the first plate-shaped component 30 and the second plate-shaped component 40 includes at least one hole 39, 49 arranged in each portion 32, 34, 42, 44 of the two plate-shaped components 30, 40. The hole may be a through hole. The through hole 39 arranged in the first plate-shaped component 30 may be internally threaded. The connecting device also includes a bolt 29. Optionally, a washer 23 may also be used.

[0068] Still referencing Figure 5a Two through holes 39 and 49 are arranged in the two portions 32, 34, 42, 44 of each plate-shaped component 30, 40. As can be seen, all the through holes 39 and 49 in the two portions 32, 34, 42, 44 of each plate-shaped component 30, 40 are vertically aligned.

[0069] One side of the first plate-shaped member 30 includes a portion for connection with the outer wall sections (72a, 72b; as shown in the image). Figure 4 A pair of longitudinally extending grooves 37 (shown and discussed) mate with corresponding ridges. This facilitates accurate positioning of the first plate-shaped member 30 and alignment of the first plate-shaped member with the second plate-shaped member 40. In related embodiments (not shown), the second plate-shaped member 40 may also have additional ridges for engaging with the upright member (…). Figure 4 (Not shown in the image) A longitudinally extending groove that mates with the additional ridge in conjunction with Figure 4 The ridges 77a and 77b shown extend in opposite directions.

[0070] Back Figure 5a The engaging device 20 includes tabs 134 and 135 extending perpendicularly to the surface of the second plate-shaped member 40. The tabs 134 and 135 include holes 136 and 137 for use with... Figure 5b The connector connects the two sets of mating upright members 27 and 31. This will combine... Figures 6a to 6b A more detailed description follows. In a related embodiment (not shown), the tab extends perpendicularly to the surface of the first plate-like member, and the second plate-like member has an opening that matches the cross-section of the tab, allowing the tab to pass through the opening.

[0071] Back to Figure 5a The tabs 134 and 135 are disposed between the through holes 49 associated with the corresponding portions 42 and 44. Furthermore, the tabs 134 and 135 are arranged offset relative to the vertically aligned through holes 49.
