Description

[0001] This application is a divisional application of Chinese Patent Application No. 202280011665.5, filed on January 21, 2022, entitled "Storage container, system including one or more of the storage containers and method of assembling the storage container". Technical Field

[0002] This invention relates to an automated storage and retrieval system for storing and retrieving containers, and more particularly to a fire-resistant storage container, a system comprising one or more of the storage containers, and a method for assembling the storage containers. The storage container is particularly suitable for use in an automated storage and retrieval system (ASRS) in which storage containers are stacked one on top of another to form a stack, and in which the storage containers can be retrieved by a container handling vehicle or robot operating on a track system extending along a first direction X and a perpendicular second direction Y. Background Technology

[0003] Figure 1 A typical prior art automated storage and retrieval system 1 with a frame structure 100 is disclosed, and Figure 2 and Figure 3 Two different prior art container handling vehicles, 201 and 301, suitable for operation on such system 1 are disclosed.

[0004] The frame structure 100 includes upright members 102, horizontal members 103, and storage volumes comprising storage columns 105 arranged in rows between the upright members 102 and the horizontal members 103. In these storage columns 105, storage containers 106 (also referred to as boxes) are stacked one on top of another to form a stack 107. Members 102 and 103 can typically be made of metal, such as extruded aluminum profiles.

[0005] 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. Multiple container handling vehicles 201, 301 operate on the track system 108 to raise and lower storage containers 106 from storage columns 105 into the columns, and also to 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 201, 301 along a first direction X across the 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 the container handling vehicles 201, 301 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 through access openings 112 in the track system 108. Container handling vehicles 201 and 301 can move laterally above storage column 105, that is, in a plane parallel to the horizontal XY plane.

[0006] During the raising of containers from column 105 and the lowering of containers into the column, the upright members 102 of the frame structure 100 can be used to guide the storage containers. The stack 107 of containers 106 is typically self-supporting.

[0007] Each prior art container handling vehicle 201, 301 includes a vehicle body 201a, 301a and a first set of wheels and a second set of wheels 201b, 301b, 201c, 301c, which respectively enable the container handling vehicle 201, 301 to move laterally in the X and Y directions. Figures 2 to 3 In this configuration, two wheels in each group are fully visible. The first group of wheels 201b and 301b are arranged to engage with two adjacent tracks of the first group of tracks 110, and the second group of wheels 201c and 301c are arranged to engage with two adjacent tracks of the second group of tracks 111. At least one group of wheels 201b, 301b, 201c, and 301c can be raised and lowered, such that the first group of wheels 201b and 301b and / or the second group of wheels 201c and 301c can engage with the corresponding set of tracks 110 and 111 at any time.

[0008] Each prior art container handling vehicle 201, 301 also includes a lifting device (not shown) for vertically transporting the storage container 106, such as raising the storage container 106 from the storage column 105 and lowering the storage container 106 into the storage column. The lifting device includes one or more clamping / engaging devices adapted to engage the storage container 106, and these clamping / engaging devices can be lowered from the vehicles 201, 301 such that the position of the clamping / engaging devices relative to the vehicles 201, 301 can be adjusted in a third direction Z orthogonal to the first direction X and the second direction Y. Some portions of the clamping devices of the container handling vehicle 301 are... Figure 3 As shown, denoted by reference numeral 304, the clamping device of the container handling device 201 is located... Figure 2 Inside the main body of the vehicle, 201a.

[0009] Traditionally, and also for the purposes of this application, Z=1 denotes the uppermost layer of the storage container, i.e., the layer directly below the track system 108; Z=2 denotes the second layer below the 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 1 The Cartesian coordinate system X, Y, Z shown is... Figure 1 The storage container marked 106' can be said to occupy storage positions X=10, Y=2, Z=3. Container transport vehicles 201 and 301 can be said to travel in layer Z=0, and each storage column 105 can be identified by its X and Y coordinates.

[0010] 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.

[0011] Each prior art container handling vehicle 201, 301 includes a storage compartment or space for receiving and loading the storage container 106 when transporting the storage container 106 across the track system 108. The storage space may include a cavity centrally located within the vehicle body 201a, such as... Figure 2 The contents of the above, as shown in, and described, for example, in WO2015 / 193278A1, are incorporated herein by reference.

[0012] Figure 3 Alternative constructions of the container handling vehicle 301 with a cantilever structure are shown. Such a vehicle is described in detail, for example, in NO317366, the contents of which are also incorporated herein by reference.

[0013] Figure 2 The central cavity container handling vehicle 201 shown may have a coverage area that covers a region along the X and Y directions, the size of which is generally equal 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”.

[0014] Alternatively, the coverage area of ​​the central cavity container transport vehicle 101 may be larger than the lateral area defined by the storage column 105, as disclosed in WO2014 / 090684A1.

[0015] The track system 108 typically includes a track with grooves in which the vehicle's wheels travel. Alternatively, the track may include upwardly projecting elements, where the vehicle's wheels 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.

[0016] WO2018 / 146304 (the contents of which are incorporated herein by reference) shows a typical construction of a track system 108 comprising tracks and parallel guides in both the X and Y directions.

[0017] In the frame structure 100, most columns 105 are storage columns 105, that is, columns 105 stored in storage containers 106 in the form of stacks 107. However, some columns 105 may serve other purposes. Figure 1 In this context, columns 119 and 120 are dedicated columns for unloading and / or picking up storage containers 106 using container handling vehicles 201 and 301, enabling their transport to retrieval stations (not shown), where storage 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 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 and transported by any container handling vehicle to port columns 119 and 120 for further transport to the retrieval station. Note that the term "inclined" refers to the transport of storage containers 106 with a general transport orientation in one of the directions between horizontal and vertical.

[0018] exist Figure 1 In the first port column 119, for example, it can be a dedicated unloading port column, in which container handling vehicles 201 and 301 can unload the transported storage container 106 to the storage station or transfer station, and the second port column 120 can be a dedicated pickup port column, in which container handling vehicles 201 and 301 can pick up the storage container 106 that has been transported from the storage station or transfer station.

[0019] The storage and retrieval station is typically a pick-up station or a stocking station where product items are removed from or positioned within the storage container 106. At the pick-up station or stocking station, the storage 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 the storage container 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.

[0020] Storage containers are typically transported between port lines 119, 120 and the access station using a transmitter system that includes a transmitter.

[0021] If port columns 119, 120 and access stations are located at different heights, the conveyor system may include a lifting device with vertical components for vertically transporting storage container 106 between port columns 119, 120 and access stations.

[0022] The transport 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.

[0023] When you need to access the stored Figure 1 When a storage container 106 is located in a column 105 as disclosed, a container handling vehicle 201, 301 is instructed to remove the target storage container 106 from its position and transport the storage container to the unloading port column 119. This operation involves moving the container handling vehicle 201, 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 device (not shown) of the container handling vehicle 201, 301, 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 positioned above the target storage container 106, the operation also involves 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 vehicle subsequently used to transport the target storage container to the 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 specifically designed for the task of temporarily removing storage containers 106 from storage columns 105. Once the target storage container 106 has been removed from the storage column 105, the temporarily removed storage container 106 can be repositioned back into the original storage column 105. However, alternatively, the removed storage container 106 can be repositioned to another storage column 105.

[0024] When storage container 106 is to be stored in a column 105, a container handling vehicle 201, 301 is instructed to pick up storage container 106 from pick-up port column 120 and transport the storage container to a position above the storage column 105 to which it is to be stored. After any storage container 106 positioned at or above the target location within stack 107 has been removed, the container handling vehicle 201, 301 positions the storage container 106 at the desired location. The removed storage container 106 can then be lowered back into storage column 105 or repositioned to another storage column 105.

[0025] In order to monitor and control the automated storage and retrieval system 1, such as monitoring and controlling 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, so that the desired storage container 106 can be delivered to the desired location at the desired time without the container transport vehicles 201, 301 colliding with each other, the automated storage and retrieval system 1 includes a control system 500, which is typically computerized and typically includes a database for keeping track of the storage containers 106.

[0026] Typically, buildings or sites with installed ASRS (Automatic Fire Protection System) are equipped with sprinkler systems to respond to fire situations. These sprinkler systems are usually installed on rooftops and are costly to invest in. Specifically, in smaller ASRSs, such as miniature systems with a limited number of storage containers or boxes and a limited number of container handling vehicles, the regulatory requirements for fires involving expensive sprinkler systems can constitute a significant portion of the overall ASRS investment cost. In some cases, the cost of a sprinkler system may prevent the installation of a planned ASRS.

[0027] The object of this invention is to enable the storage of containers for delivery to micro-performed ASRS installations. Summary of the Invention

[0028] The invention is set forth and characterized in the independent claims, while the dependent claims describe other features of the invention.

[0029] This invention relates to a storage container. The storage container preferably has a uniform size and can be operated by a container handling vehicle as mentioned in the "Background Art".

[0030] A storage container for an Automated Storage and Retrieval System (ASRS) is disclosed, the storage container being configured to be stacked in a stacking manner, wherein a lower layer of storage containers supports one or more storage containers positioned above it, the storage containers being adapted to be lifted by clamps on a lifting device, such that the storage containers can be lifted from above, wherein the storage containers include: bottom; Four sides, each hinged to the bottom edge; The four corner posts are each constructed such that when a pair of sides are positioned relative to the bottom and at approximately 90 degrees relative to each other, the pair of adjacent sides are interconnected in the horizontal direction.

[0031] This means that two adjacent sides are locked together and prevent these two adjacent sides from moving relative to each other in the horizontal direction when the bottom of the storage container is supported on a surface (i.e., during normal use of the storage container).

[0032] The bottom is preferably rectangular or square in shape.

[0033] The fact that each of the four sides is hinged to the edge of the bottom means that these sides are connected by a continuation of the bottom material. The five sides of the container can be provided by a connecting area, in which the hinged connection can be formed, for example, by a sheet having weak lines along which the sides are folded, or by separate sheets adjacent to each other along the edge of the bottom.

[0034] It has four corner posts, each corner post being constructed such that when a pair of sides are positioned relative to the bottom and at approximately 90 degrees relative to each other, the pair of adjacent sides are interconnected in the horizontal direction. This feature should be understood as 90 degrees + / - 5 degrees.

[0035] In a preferred embodiment, the corner posts are structural posts that, in a sense, are constructed to support all the storage containers positioned above them. In other words, the corner posts bear all or most of the weight of all the storage containers positioned above them. This can be achieved by using a relatively rigid material with high strength to manufacture the corner posts and by adjusting the construction so that the corner posts, rather than the sides, bear the vertical load from the storage containers located above. The construction of the corner posts and the engagement of the sides with the posts can be designed to lock the sides in their approximately 90-degree positions during the assembly of the storage containers, thereby stabilizing the structure of the storage containers. Thus, the sides only need to be designed with limited vertical strength sufficient to bear the load of the storage containers and any items contained therein (i.e., at most in the range of 30-40 kg).

[0036] The storage container may include lifting holes along its upper edge, which are arranged in a suitable position complementary to the clamping position of the lifting device and have dimensions complementary to the dimensions of the lifting device, thereby enabling the storage container to be lifted by the clamping of the lifting device.

[0037] In order for the bottom storage container in a stack to support, for example, 15 boxes, each with a maximum weight of 30 kg, the corner posts should be designed to bear at least 150 kg each (assuming a safety margin of 150 kg (4 x 150 kg = 600 kg, while the maximum weight of the stack is 15 boxes x 30 kg = 450 kg).

[0038] By designing the corner posts to bear all or most of the vertical load from the storage container above, the sheet material of a storage container does not need to be sized to bear a load greater than the weight of the storage container plus any of its contents (e.g., up to 30 kg). Instead of transmitting the vertical load from the storage container above, the sheet material can function under tension to stabilize the position of the corner posts, allowing the corner posts to provide the primary load path for the vertical load.

[0039] The bottom and sides of the storage container may comprise sheet material, which may be provided as a blank from which the bottom and four sides are formed. Each side is connected to a corresponding edge of the bottom via a movable hinge provided by a weak line extending between each side and the bottom, such that the corresponding side can be folded relative to the bottom along the weak line. Thus, the bottom and sides can be made of the same material.

[0040] This could enable the pre-manufacturing of sheet material and the transport of multiple storage containers stacked inside each other, thus significantly reducing the amount of shipping required. Furthermore, the height of the container can be easily changed by simply altering the dimensions of the sides of the sheet material.

[0041] Sheet materials can be manufactured using known techniques. For example, sheet materials can be punched or stamped.

[0042] To improve the strength of the sides, the sheet material may be provided with recesses extending vertically (when the sides are folded upwards). These recesses are formed within the sheet material (not through holes). Similarly, a recess may be provided at the bottom. Alternatively, other means of increasing strength may be employed, such as increasing the thickness of the sides and / or bottom, or attaching separate reinforcements to the sides and / or bottom.

[0043] A movable hinge is a thin, flexible hinge (bending bearing) made of the same material as the two rigid members it connects to. The movable hinge is typically thinned or cut to allow the rigid members to bend along the hinge line.

[0044] A weak line can be a line where the amount of sheet material is reduced. This reduction can be achieved by thinning the sheet, by creating holes, or both.

[0045] The relatively thinner portion of the sheet material along the weak line forms a relatively weak area within the sheet material, ensuring the formation of bends or folds along the desired lines of the sheet material. Therefore, the weak line is the bottom folded edge.

[0046] Weak lines may include through holes. Through holes can accommodate relatively weak areas or lines in the sheet material and ensure that bends are formed along the desired lines in the sheet material.

[0047] Through holes can comprise more than 30% of the weak line. Alternatively, through holes can comprise more than 30% or less than 30% of the weak line, such as more than 20% and 40% of the weak line.

[0048] In one aspect, the cross-sectional area of ​​the through hole can be large enough to allow water to flow through. The through hole can be formed as a slot, orifice, or groove, with a size sufficient to allow water to drain out by natural flow.

[0049] In one aspect, the through hole includes: - An inlet, located on the inner surface of the storage container; and - An outlet is located on the outer surface of the storage container. The inlet can be located at a height equal to or higher than the outlet of the through-hole. This configuration ensures that the centerline of the through-hole can extend horizontally or downwards from the inside of the storage container to the outside. That is, the centerline of the through-hole can be a descending line extending outwards from the weak line when the storage container is assembled.

[0050] As shown above, through holes can be arranged along the weak line. Alternatively or additionally, through holes can be formed in the bottom near or close to the weak line. Arranging through holes at these locations also ensures that the flowing water enters the lower storage container in the stack. In order for most of the water to flow into the lower storage container, and because the storage containers are stacked one on top of another (rather than partially entering each other), wherein at least the corner posts of the stacked storage containers are supported by one on top of the other, the center line of the through hole should preferably form a negative angle relative to the horizontal plane. For example, in the case where the bottom is in a horizontal plane, the center line of the through hole forms a negative angle relative to the bottom.

[0051] The weak line can be a straight line. This ensures that the folds form along a straight line. A straight or linear line ensures that the sides bend along the desired line, so that the final storage container meets requirements in terms of form and shape. On-site, it is best to test all storage containers to identify potential damage during transportation; this is a standard procedure nowadays after shipping cast plastic containers. Irregularly shaped storage containers will not fit in storage rows or stacks and / or may get stuck in rows, and / or the clamps of the lifting device may have difficulty holding the storage containers.

[0052] Sheet material can be stamped to provide the contours for the bottom and four sides. Weak lines may be formed simultaneously. The sides and bottom of the storage container can be shaped to increase strength.

[0053] The bottom and sides can be made of metal sheet material, plastic sheet material, cardboard sheet material, composite sheet material or other suitable material.

[0054] The bottom and sides can be made of aluminum or steel.

[0055] In a preferred embodiment, fire-resistant materials such as metal or fire-resistant plastic are used to manufacture the storage container to avoid the use of expensive sprinkler systems in miniature ASRS installations.

[0056] The upper end of the corner post can be at the same level as or above the top edge of the side. Similarly, the lower end of the corner post can be at the same level as or below the lower end of the side. This arrangement ensures that the upper end of the corner post contacts the lower side of the corner post of the storage container above, which again ensures that all or most of the vertical load of the storage container above is supported by the corner post.

[0057] Corner posts can be made of plastic materials. For example, corner posts can be molded and can include a profile configured to engage with the sides of a storage container.

[0058] A storage container according to any of the preceding claims, wherein the corner posts include longitudinal notches located on the outer surface. These longitudinal or vertical notches facilitate lifting of the storage container by clamps on a lifting device, as the container guide of the lifting device can be guided along the notches on the different corner posts.

[0059] Corner posts can also have shapes and materials that simplify the guidance of upright members along the frame. Since upright members are typically made of aluminum, at least the surfaces of the corner post that contact the upright members should be made of a different material than aluminum to prevent scratches. However, in the case where the corner post is made of aluminum, the surfaces that contact the upright members can be coated or otherwise treated with a different material than aluminum.

[0060] Each side panel may include a top edge and two opposing side edges, and each side panel may be folded to form a fold at the side edge, thereby providing an outwardly extending rib at each side edge, and each corner post may include a pair of grooves extending along its longitudinal direction for receiving corresponding outwardly extending ribs from a pair of adjacent sides. This locks the two adjacent side panels relative to each other in a rectangular (i.e., vertical) manner.

[0061] The crease in the sheet material should locally harden the area to provide additional strength – and the crease should provide a flange (or the crease can be formed into another shape, such as a curl), extending at an angle (ideally perpendicular, but other angles are also very effective) to the plane of the side. This forms a shaped portion (corner, rib, flange, plug, or curl – in the case of a curled edge, etc.), which then locks in the longitudinal (i.e., vertical) groove of the corner post when slid in to engage, thus resisting any tension or circumferential force in the container that forces the sides apart.

[0062] The distance between the two side edges of a side section can be shorter than the distance between the two bottom edges. Thus, the adjacent side edges of adjacent sides may not be sufficient to form the true geometric angles inside the storage container. Corner posts can be fixed to these edges and provide structural bridges for the transfer of circumferential forces from one side section to another. Furthermore, the corner posts fix the sides in a spaced-apart configuration.

[0063] The top edge may form part of the flange portion of the side, and the corner post may include a snap-lock connection for locking the corner post to the flange portion.

[0064] The flange portion may include a main portion, a middle portion and an outer portion, and the top edge may form the upper end of the outer portion.

[0065] The middle section can fold outwards relative to the main section, and the outer section folds upwards relative to the middle section, thus misaligning the outer section with respect to the main section. This construction strengthens the sides, as they are hardened through the flange portions. This reduces the risk of the storage container bending.

[0066] The main part and the outer part are preferably substantially parallel.

[0067] The cross-sectional area formed by the outer portion of the side can be larger than the bottom in all directions, and therefore, the through-hole at the bottom of the storage container supported directly above ensures that all water flowing through the through-hole into the storage container above is guided into the storage container via the outer, middle, and main portions of the flange portion. In other words, the outer portion of the flange portion located at the top of the side extends outward to guide water flowing out of the through-hole, which forms a weak line in the upper storage container. That is, the through-hole functions both to form a weak line and to guide water downward through to the lower storage container in the event of a fire. Thus, the outer portion of the side can be arranged in all horizontal directions to exceed any through-hole in the storage container supported directly above.

[0068] The length of the side sections along the X and Y directions is preferably longer than the distance between the two upright members along the X and Y directions. This positions the side edges of the storage container relative to the upright members of the ASRS frame such that, in the event that the corner posts melt during a fire and one or more of the four side sections move outward due to no longer being supported by the corner posts, the side sections will rest against the upright members. This will maintain the integrity and stability of most of the stack of storage containers and prevent the stack from collapsing. This may be particularly important in ASRS where the bottom and sides are made of fire-resistant materials (e.g., metal) while the corner posts are made of non-fire-resistant materials (e.g., plastic). The combination of side sections made of metal (such as aluminum or steel) with water may be particularly advantageous because aluminum is a good thermal conductor and water has a high specific heat capacity, so together they can effectively absorb a large amount of heat from the combustion zone to help prevent the spread of fire. Therefore, the combination of aluminum and water can provide more benefits than non-combustible materials, at least at relatively low fire temperatures where aluminum does not burn.

[0069] In one embodiment, when the top edge is folded to form a folded portion, the storage container 106 may also include a closing locking frame for locking all the top edges of the sides and corner posts relative to each other.

[0070] The top edge and corner posts may include upward-oriented recesses, and the locking frame may include complementary downward-oriented protrusions for locking with the recesses. Locking between the recesses and protrusions can be achieved via a snap-lock connection.

[0071] In an alternative embodiment, the top edge may be folded, and the storage container may further include a closure locking frame for locking all the top edges of the sides and corner posts relative to each other. In this embodiment, the closure locking frame includes an upward-oriented recess.

[0072] An Automated Storage and Retrieval System (ASRS) is also disclosed, comprising a two-dimensional track system including: a first set of parallel tracks arranged to guide container transport vehicles to move along a first direction X on top of a frame structure; and a second set of parallel tracks arranged perpendicular to the first set of tracks to guide the container transport vehicles to move in a second direction Y perpendicular to the first direction X, wherein multiple container transport vehicles operate on the track system, and wherein the system includes one or more storage containers as defined above.

[0073] A transport storage container and a method for assembling the storage container on-site are also disclosed, wherein the storage container includes: bottom; Four sides, each hinged to the bottom edge; Four corner pillars, each corner pillar configured such that when a pair of sides are positioned approximately 90 degrees relative to the bottom and relative to each other, the pair of adjacent sides are interconnected in the horizontal direction; and wherein the method includes the following steps: - Fold each side section at an angle between 20 and 85 degrees relative to the bottom; - On a public transport platform, partially folded sides and bottoms are stacked to at least partially enter into or be located within each other; - Place the cornerstone on the platform; - Transport the folded sides and bottom stacks of these parts, along with the corner posts, to the ASRS site; - Assemble storage containers on-site.

[0074] The ability to embed or house material sheets within each other makes it possible to transport storage containers for semi-finished products, enabling final assembly to be performed on-site at ASRS. This reduces the amount of transport required for the storage containers by one-third compared to existing solutions where storage containers are cast as a single piece and stacked on top of one another for transport from the factory to the ASRS installation site.

[0075] On-site assembly of storage containers can be performed by human operators or robotic operators.

[0076] The transport platform can be a standardized pallet, such as a European standard pallet.

Detailed Implementation

[0089] In the following discussion, embodiments of the invention will be described in more detail with reference to the accompanying drawings. However, it should be understood that these drawings are not intended to limit the invention to the subject matter depicted in the drawings.

[0090] The framework structure 100 of the automatic storage and retrieval system 1 is based on the above combination Figures 1 to 3 The existing technical framework structure 100 described herein is constructed with a plurality of upright members 102 and a plurality of horizontal members 103, the horizontal members being supported by the upright members 102, and the framework structure 100 also includes a first upper track system 108 in the X and Y directions.

[0091] The frame structure 100 also includes storage compartments in the form of storage columns 105 disposed between members 102 and 103, wherein storage containers 106 can be stacked in the form of stacks 107 within the storage columns 105.

[0092] The frame structure 100 can have any size. Specifically, it should be understood that the frame structure can be larger than... Figure 1 The frame structures disclosed herein are wider and / or longer and / or deeper. For example, the horizontal range of frame structure 100 can be greater than 700×700 columns and its storage depth can be greater than 12 containers.

[0093] First embodiment of the storage container

[0094] Now refer to Figures 4A to 10 A first embodiment of the automatic storage and retrieval system according to the present invention will be discussed in more detail.

[0095] Figure 4A This is a top perspective view of a storage container 108 according to a first embodiment of the present invention. The storage container 106 is configured as described above. Figure 1 The Automated Storage and Retrieval System (ASRS) 1 (see...) Figure 1 Used in ) and through the combination as above Figure 2 and Figure 3 The container handling vehicles 201 and 301 are lifted, but other types of container handling vehicles 201 and 301 may also be used. Storage container 106 is also configured for stacking 107 of storage containers 106 (see [link]). Figure 1 The storage containers 106 are stacked in a manner such that the lower storage container 106 supports one or more storage containers 106 positioned above it. The storage containers 106 are also adapted to be lifted via lifting holes 41 through clamps 304 on a lifting device (see [link to lifting device]). Figure 3 The storage container 106 is raised so that it can be lifted from above. The disclosed storage container 106 has a rectangular bottom 10 and four sides 11', 11'', 11''', 11''''. Each side 11', 11'', 11''', 11'''' is hinged to a corresponding edge 14', 14'', 14''', 14''' of the bottom 10. Four corner posts 12', 12'', 12''', 12''''' are also disclosed. Each corner post 12', 12'', 12''', 12''''' is configured such that when a pair of sides 11', 11'', 11''', 11''''' are positioned relative to the bottom 10 and at approximately 90 degrees relative to each other (i.e., as shown in the image), the storage container 106 is raised. Figure 4AAs shown in the diagram, the pair of adjacent sides 11', 11'', 11''', 11'''' are interconnected with each other in the horizontal direction. The first short side 11' (i.e., the "first side") is connected to the first long side 11'' (i.e., the "second side") via the first corner post 12'. The first long side 11'' (i.e., the "second side") is further connected to the second short side 11''' (i.e., the "third side") via the second corner post 12''. The second short side 11''' (i.e., the "third side") is connected to the second long side 11'''' (i.e., the "fourth side") via the third corner post 12'''. The second long side 11'''' (i.e., the "fourth side") is connected to the first short side 11' (i.e., the "first side") via the fourth corner post 12''''.

[0096] Figure 4B yes Figure 4A An enlarged top view of section A of the storage container 106. Section A is a detailed view of the junction between the third side 11''' and the fourth side 11''''. Both the first side 11' and the fourth side 11'''' disclosed include a top edge 18 and two opposing side edges (only one side edge of each side is disclosed). The first and fourth sides 11', 11'''' are folded to form folds 20 at the side edges, thereby providing outwardly extending ribs 19 at each side edge. The disclosed corner post 12'''' has a pair of grooves 21 extending along its longitudinal direction, each groove for receiving one of the corresponding outwardly extending ribs 19 from the first and fourth sides 11', 11''''.

[0097] The locking frame 70 is connected to the top edge 18 of the side 11'-11''''.

[0098] The disclosed side portions 11'-11'''' and bottom portion 10 have recesses 40 to increase strength. The disclosed side portions 11'-11'''' have recesses extending vertically (when the side portions 11'-11'''' are folded upwards). The recesses are shaped (i.e., not through holes). Similarly, the disclosed bottom portion 10 has a recess extending from the second side portion 11'' toward the fourth side portion 11'''' (i.e., extending between the first long side portion and the second long side portions 11'', 11'''' of the bottom portion 10).

[0099] like Figure 4B As can be seen, the disclosed fourth corner post 12'''' has a longitudinal notch 17 on its outer surface. This longitudinal or vertical notch 17 facilitates the passage of the storage container 106 through the clamp 304 on the lifting device (see...). Figure 3The lifting device is lifted because the box guide (not shown) of the lifting device can be guided along the notches 17 on the different corner posts 12', 12'', 12''', 12''''.

[0100] The disclosed corner post 12'''' also has an outer surface 42 for connection with the upright members 102 of the frame structure 100 (see Figure 1 Sliding contact. If the upright member 102 is made of aluminum, the outer surfaces 42 of at least the corner posts 12', 12'', 12''', 12'''' guided by the upright member 102 should be coated or made of a material other than aluminum to avoid scratches and noise caused by aluminum-to-aluminum sliding during the lifting and lowering of the storage container 106 within the frame structure 100.

[0101] Figure 4C From Figure 4A The perspective view shown below reveals more details of the recess in the bottom 10. Additionally, the lifting hole 41 is visible from below.

[0102] Figure 4D This is a side view of the relatively long side (i.e., the second side 11'' (extending along the X direction)) of the storage container 106 according to the first embodiment. Figure 4D As can be seen, the upper ends of the first and second corner posts 12', 12'' are at a horizontal level above the top edge 18 of the second side 11''. Furthermore, as shown, the lower ends of the first and second corner posts 12', 12'' are at a horizontal level below the lower end of the second side 11''. This arrangement ensures that the upper ends of the corner posts 12'-12'''' contact the lower side of the corner posts of the storage container above, which again ensures that all or most of the vertical load of the storage container above is supported by the corner posts 12'-12''''.

[0103] Figure 4E This is a side view of the storage container according to the first embodiment, showing the relative height of the short side (i.e., the first side 11') compared to the height of the first corner post and the second corner posts 12', 12''.

[0104] Figure 4F This is a top view of the storage container 106 according to the first embodiment.

[0105] Figure 4GThis is a top view of sheet material 13 forming a rectangular bottom 10 and four sides 11', 11'', 11''', 11'''' of the storage container 106 according to the first embodiment. Sheet material 13 may be provided as a blank from which the bottom 10 and the four sides 11', 11'', 11'''' are made. Each side 11', 11'', 11'''' is connected to a corresponding edge 14', 14'', 14'''' of the bottom 10 by a movable hinge provided by weak lines 14', 14'', 14''', 14''''. Weak lines 14', 14'', 14''', 14'''' extend between each side 11', 11'', 11''', 11''' and the bottom 10, such that the corresponding side 11', 11'', 11''', 11'''' can be folded relative to the bottom 10 along the weak lines 14', 14' ...

[0106] Weak lines 14', 14'', 14''', 14'''' may be lines indicating a reduction in the amount of sheet material 13. Alternatively or additionally, weak lines 14', 14'', 14''', 14'''' may include through holes 15. Figure 4G As shown, the through hole 15 can occupy most of the weak line; for example, as shown, the through hole can occupy more than 30% of the weak lines 14', 14'', 14''', 14''''.

[0107] As shown, in order to simplify the folding of the sides 11', 11'', 11''', 11'''', the weak lines 14', 14'', 14''', 14'''' can be straight lines.

[0108] like Figure 4G As shown, sheet material 13 can be stamped to provide the contours of the bottom 10 and the four sides 11', 11'', 11''', 11''''. During the contouring step, the stamping process can also form other features, such as weak lines 14', 14'', 14''', 14'''' and / or through holes 15.

[0109] The bottom 10 and the sides 11', 11'', 11''', 11'''' can be made of metal sheet material 13, plastic sheet material 13, cardboard sheet material 13, composite sheet material 13, etc. When made of metal sheet material 13, the bottom and sides can be made of, for example, aluminum sheet material 13 or steel sheet material 13.

[0110] Figure 4H yes Figure 4G The side perspective view of the sheet material shows that the sides 11', 11'', 11''', 11'''' have been folded upward at approximately 75 degrees relative to the bottom 10 to facilitate stacking of the sheet material 13 during transport.

[0111] Figure 4I yes Figure 4G and Figure 4H A side perspective view of sheet material 13, wherein sides 11', 11'', 11''', 11'''' have been folded upwards at approximately 90 degrees relative to the bottom 10. In this position, two adjacent sides 11'-11'''' form a 90-degree angle between them. Furthermore, as... Figure 4I As can be seen, the distance between the two side edges of a side 11'-11'''' is shorter than the distance between the two edges 14'-14'''' of the bottom 10, making the adjacent side edges of the adjacent sides 11', 11'', 11''', 11'''' insufficient to form the true geometric angle inside the storage container 106, thus forming an opening 34 between them.

[0112] Now for reference Figure 4G , Figure 4H , Figure 4I The top edge 18 of the storage container forms part of the flange portion 30 of the sides 11', 11'', 11''', 11''''. The flange portion 30 includes a main portion 31, a middle portion 32, and an outer portion 33. The top edge 18 forms the upper end of the outer portion 33. The middle portion 32 is folded outward relative to the main portion 31, and the outer portion 33 is folded upward relative to the middle portion 32. Thus, the middle portion 32 forms a step or flange between the main portion 31 and the outer portion 33. This construction strengthens the sides 11'-11'''' because these sides are hardened by the flange portion 30. This reduces the risk of the storage container bending. To make the storage container 106 stackable and maximize storage volume, the main portion 31 and the outer portion 33 are shown as parallel.

[0113] like Figure 4I As shown, the middle portion 32 of the flange portion 30 may include a locking hole 35 for abutting against a pin member 36 on the corner post 14' (see...). Figures 5A to 5C Lock it.

[0114] Figure 5A , Figure 5B and Figure 5C This is a detailed view of the corner posts 12'-12'''' of the first embodiment of the storage container, wherein, Figure 5A It is a side-view stereoscopic view of the corner prism 12'-12''''. Figure 5B It is a top view of the corner prism 12'-12'''', and Figure 5C This is a side view of the corner prism 12'-12''''.

[0115] The corner posts 12'-12'''' include a first pin member and a second pin member 36 for locking the locking holes 35 in the middle portion 32 of the flange portion 30 of the corresponding side 11'-11''''. The corner posts 12'-12'''' are also provided with a snap-lock connection portion 37 for locking the corner posts 12', 12'', 12''', 12'''' to the flange portion 30. When the outer portion 33 of the flange portion 30 enters the recess 38 provided on the lower side of the upper portion of the corner post 12'-12'''', the snap-lock connection portion 37 contacts the inner surface of the side 11'-11'''' and is forced to connect with the side 11'-11''''.

[0116] Figure 6 This is an exploded view of the corner posts 12'-12'''' and the side portions 11'-11'''' of the storage container 106 according to the first embodiment.

[0117] Figure 7A A stack 107 of storage containers 106 according to the first embodiment is shown.

[0118] Figure 7B yes Figure 7A A detailed view of section G shows the relative position of the through hole 15 in the upper storage container 106 with respect to the outer portion 33 of the flange portion 30 of the lower storage container 106. The cross-sectional area of ​​the through hole 15 is large enough to allow water to flow through. Figure 7C yes Figure 7B A simplified view showing the storage container 106, which is located relatively upper, and the centerline 16 of the through hole 15 in the upper storage container 106 is shown. The cross-sectional area formed by the outer portions of the sides 11', 11'', 11''', and 11'''' is larger than the bottom 10 in all directions. Therefore, the through hole 15 of the bottom 10 of the storage container 106, which is supported directly above, is located inside the outer portion 33, such that any water flowing through the through hole 15 of the upper storage container 106 is guided into the storage container 106 via the outer portion 33, the middle portion 32, and the main portion 31 of the flange portion 30.

[0119] like Figure 7B and Figure 7C As can be seen, the disclosed through-hole 15 has an inlet 43 disposed on the inner surface of the storage container 106 and an outlet 44 disposed on the outer surface of the storage container 106. As disclosed, the inlet 43 is disposed at a height higher than the outlet 44 of the through-hole 15. Furthermore, refer to... Figure 7B and Figure 7C The centerline 16 of the through hole 15 forms a negative angle α with respect to the horizontal plane P. The horizontal plane P is shown as being parallel to the bottom 10 of the storage container 106.

[0120] Figure 7D yes Figure 7B A simplified view is provided, in which some details of the upper and lower storage containers 106 have been omitted to better illustrate how water flows from the upper storage container 106 to the lower storage container 106 through the through-hole before being guided by the outer portion 33, middle portion 32, and main portion 31 of the flange portion 30 into the lower storage container 106. Thus, the middle portion 32 forms a step or flange between the main portion 31 and the outer portion 33. In other words, the outer portion 33 of the flange portion 30, located at the top of the side portions 11'-11'''', extends outward to guide water flowing from the through-hole 15, which forms a weak line in the upper storage container 106; that is, the through-hole 15 functions both to form the weak line 14'-14'''' and to guide water downward through to the lower storage container 106 in the event of a fire.

[0121] In this way, the outer portion 33 of the side can be arranged in all horizontal directions outside any through hole of the storage container supported directly above.

[0122] Therefore, the construction of the flange portion 30 relative to the through hole 15 ensures that water from above (whether from the building's sprinkler system or from the upper storage container 106 or other sources) is guided to the lower storage container 106, thereby providing better fire suppression.

[0123] Figure 7E This is a perspective view of a stack 107 of storage containers 106 according to the first embodiment, and shows the gap 39 formed between the sides 11'-11'''' of the two storage containers stacked on top of each other.

[0124] Figure 8A This is a top view showing the position of the side edges of the side portions 11'-11'''' relative to the upright members 102 of the frame structure 100. Figure 8B Is with Figure 8AA similar view is shown, in which corner posts 12'-12'''' have been removed. The lengths of the sides 11'-11'''' along the X and Y directions are preferably longer than the distances between the two upright members 102 along the X and Y directions. This positions the side edges of the storage container 106's sides 11'-11'''' relative to the upright members 102 of the ASRS frame structure 100 such that, in the event that corner posts 12'-12'''' melt during a fire and one or more of the four sides 11'-11''''' move outward due to no longer being supported by corner posts 12'-12''''', the sides 11'-11'''' will rest against the upright members 102, as shown by line M. This will maintain the integrity and stability of most of the stack 107 of storage containers and prevent the stack 107 from collapsing.

[0125] Figure 9A This is an exploded view of the storage container 106 according to the first embodiment, which also includes dividers 50 that divide the capacity of the storage container 106 into separate sections. The dividers 50 are shown as having protrusions 51 on their opposite sides.

[0126] Figure 9B yes Figure 9A A detailed view of section L in the image. (See also:) Figure 9B As shown, the middle portion 32 of the disclosed flange portion 30 has a slot 52 for receiving the protrusion 51 of the separator 50.

[0127] Figure 10 A transport platform in the form of a pallet 60 is shown, on which two stacks of sheet material 13 with folded sides for transport are placed. Figure 10 The image shows two stacks of sheet material 13 with folded sides within the vertical projection of the bottom of the tray 60.

[0128] The storage container 106 according to the first embodiment can be installed on-site through the following steps: - Fold each side section 11', 11'', 11''', 11'''' to an angle between 20 and 85 degrees relative to the bottom 10; - Stack these partially folded sides 11', 11'', 11''', 11'''' and bottom 10 on tray 60 so that they are at least partially inside or within each other; - Place the corner posts 12', 12'', 12''', 12'''' on the platform ( Figure 10 (Platform with corner pillars not shown). - The stacking of these folded sides 11', 11'', 11''', 11'''' and bottom 10, as well as the corner posts 12', 12'', 12''', 12'''', are transported to the ASRS site; - Assemble storage container 106 on site.

[0129] The assembly steps may include: - Fold the sides 11', 11'', 11''', 11''' completely so that each side extends at a 90-degree angle from the bottom 10; - Slide each corner post 12', 12'', 12''', 12'''' from above to lock into the edge of a pair of adjacent sides 11', 11'', 11''', 11''''; and - The corner posts 12', 12'', 12''', 12'''' are snapped into the flange portion 30 of the storage container 106 so that the corner posts 12', 12'', 12''', 12'''' are locked into the side edges of the adjacent sides 11', 11'', 11''', 11''''.

[0130] Second embodiment of the storage container

[0131] Now refer to Figures 11A to 13E A first embodiment of the automatic storage and retrieval system according to the present invention will be discussed in more detail.

[0132] Several features are similar to those in the first embodiment described in detail above. The different features and functions will be described below. Common features will not be repeated.

[0133] Figure 11A This is a perspective view of the storage container 106 according to a second embodiment. The figure shows the storage container 106 of the Automated Storage and Retrieval System 1 (ASRS 1). The storage containers 106 are configured to be stacked in a stacking manner, wherein a lower layer of storage containers 106 supports one or more storage containers 106 positioned above it. The storage container 106 includes a lifting hole 41, allowing it to be moved via a clamp 304 on a lifting device (see [link]). Figure 3The storage container 106 is lifted so that it can be lifted from above. The disclosed storage container 106 has: a rectangular bottom 10; four sides 11', 11'', 11''', 11'''', each side hinged to an edge 14', 14'', 14'''', 14''''; and four corner posts 12', 12'', 12''', 12'''', each corner post configured to interconnect with each other in the horizontal direction when a pair of adjacent sides 11', 11'', 11''', 11'''' are positioned relative to the bottom 10 and at approximately 90 degrees relative to each other. A first short side 11' (i.e., the "first side") is connected to a first long side 11'' (i.e., the "second side") via a first corner post 12'. The first long side 11'' (i.e., the "second side") is further connected to the second short side 11''' (i.e., the "third side") via the second corner post 12''. The second short side 11''' (i.e., the "third side") is connected to the second long side 11'''' (i.e., the "fourth side") via the third corner post 12'''. The second long side 11'''' (i.e., the "fourth side") is connected to the first short side 11' (i.e., the "first side") via the fourth corner post 12''''.

[0134] The disclosed side portions 11'-11'''' and bottom 10 have recesses 40 to increase strength. The disclosed side portions 11'-11'''' have recesses extending vertically (when the side portions 11'-11'''' are folded upwards). The recesses are shaped (i.e., not through holes).

[0138] Figure 11E This is a bottom view of the storage container 106 according to the second embodiment.

[0139] Figure 11F yes Figure 11E A detailed view of section C in the image. For example... Figure 11FAs shown, the disclosed fourth corner post 12'''' has a longitudinal notch 17 on its outer surface. This longitudinal or vertical notch 17 facilitates the passage of the storage container 106 through the clamp 304 on the lifting device (see...). Figure 3 The lifting device is lifted because the box guide (not shown) of the lifting device can be guided along the notches 17 on the different corner posts 12', 12'', 12''', 12''''.

[0140] The disclosed corner post 12''' also has an outer surface 42 for connection with the upright members 102 of the frame structure 100 (see Figure 1 Sliding contact. If the upright member 102 is made of aluminum, the outer surfaces 42 of at least the corner posts 12', 12'', 12''', 12'''' guided by the upright member 102 should be coated or made of a material other than aluminum to avoid scratches and noise caused by aluminum-to-aluminum sliding during the lifting and lowering of the storage container 106 within the frame structure 100.

[0141] Figure 11G It is along Figure 11B The disclosed locking frame 70 has a snap-lock connection 37 for locking the corner post 12'. The snap-lock connection 37 extends downward from the underside of the locking frame 70 to engage with the top edge 18 of the side portions 11'-11'''' and the recess 72 at the upper end of the corner posts 12'-12'''' (e.g., Figure 12B and Figure 12C (As better shown in the image).

[0142] Figure 12A This is a top view of the sheet material 13 that forms the bottom 10 and four sides 11'-11'''' of the storage container 106 according to the second embodiment.

[0143] Figure 12AThis is a top view of the sheet material 13 forming the bottom 10 and four sides 11', 11'', 11''', 11'''' of the storage container 106 according to the second embodiment. The sheet material 13 can be provided as a blank from which the bottom 10 and the four sides 11', 11'', 11'''' are made. Each side 11', 11'', 11'''' is connected to the corresponding edge 14', 14'', 14'''' of the bottom 10 by a movable hinge provided by weak lines 14', 14'', 14''', 14''''. Weak lines 14', 14'', 14''', 14'''' extend between each side 11', 11'', 11''', 11''' and the bottom 10, such that the corresponding side 11', 11'', 11''', 11'''' can be folded relative to the bottom 10 along the weak lines 14', 14' ...

[0144] Weak lines 14', 14'', 14''', 14'''' may be lines indicating a reduction in the amount of sheet material 13. Alternatively or additionally, weak lines 14', 14'', 14''', 14'''' may include through holes 15. Figure 12A As shown, the through hole 15 can occupy most of the weak line; for example, as shown, the through hole can occupy more than 30% of the weak lines 14', 14'', 14''', 14''''.

[0145] As shown, in order to simplify the folding of the sides 11', 11'', 11''', 11'''', the weak lines 14', 14'', 14''', 14'''' can be straight lines.

[0146] like Figure 12A As shown, sheet material 13 can be stamped to provide the contours of the bottom 10 and the four sides 11', 11'', 11''', 11''''.

[0147] The bottom 10 and the sides 11', 11'', 11''', 11'''' can be made of metal sheet material 13, plastic sheet material 13, cardboard sheet material 13, composite sheet material 13, etc. When made of metal sheet material 13, the bottom and sides can be made of, for example, aluminum sheet material 13 or steel sheet material 13.

[0148] The top edges 18 of the second and fourth sides 11'', 11'''' have pre-cut slits 80 at positions complementary to the lifting holes 41 in the locking frame 70.

[0149] Figure 12B yes Figure 12A A side perspective view of the sheet material, wherein the sides 11'-11'''' have been folded upwards at approximately 90 degrees relative to the bottom 10. In this position, two adjacent sides 11'-11'''' form a 90-degree angle between them. Furthermore, as... Figure 12B As can be seen, the distance between the two side edges of a side 11'-11'''' is shorter than the distance between the two edges 14'-14'''' of the bottom 10, making the adjacent side edges of the adjacent sides 11', 11'', 11''', 11'''' insufficient to form the true geometric angle inside the storage container 106, thus forming an opening 34 between them.

[0150] Now for reference Figure 12A and Figure 12B The top edge 18 of the storage container forms part of the top portion 90 of the sides 11', 11'', 11''', 11''''. The top portion 90 includes a main top portion 91 and a folded portion 92. The top edge 18 forms the folded portion 92. The folded portion 92 folds outward relative to the main top portion 91. Thus, the folded portion 92 forms a flat platform on the top of the sides 11'-11''''. This construction strengthens the sides 11'-11'''' because these sides are hardened through the top portion 90. This reduces the risk of the storage container bending.

[0151] Figure 12C This is an exploded view of the corner posts 12'-12'''', sides 11'-11'''', and locking frame 70 of the storage container 106 according to the second embodiment. Corner post receivers 71 for receiving corner posts 12'-12'''' are shown at each corner of the bottom 10.

Figure 11F ), to provide outwardly extending ribs 19 at each side edge. Each corner post 12', 12'', 12''', 12'''' includes a pair of grooves 21 extending in its longitudinal direction (see Figure 11F (details in the text), for receiving corresponding outwardly extending ribs 19 from a pair of adjacent sides 11', 11'', 11''', 11''''.

[0153] When the top edge 18 is folded, the folded top portion 92 is as follows: Figure 12C When the locking frame 70 is pointed upwards as shown, closing the locking frame 70 locks all the top edges 18 of the sides 11', 11'', 11''', 11'''' with the corner posts 12', 12'', 12''''' relative to each other. The top edges 18 and the corner posts 12', 12'', 12''''' may have upward-oriented recesses 72, and the locking frame 70 may have complementary downward-oriented protrusions 37 for locking with the recesses 72, thereby snapping the locking frame 70 into the sides 11'-11'''' and the corner posts 12'-12''''.
