Description

Title of the invention: Order preparation method, and assembly configured for implementing the method

[0001] This disclosure relates to an order picking process. This disclosure further relates to an assembly comprising a storage and retrieval system and cartons containing one or more items, the system comprising a control unit configured for implementing the order picking process. technical field

[0002] This disclosure falls within the domain of ASRS (for "automated storage and retrieval system") storage solutions, namely automated storage and retrieval systems, hereinafter referred to as ASRS systems, which are computer-controlled installations configured to automatically move loads, generally containers, into specified storage locations of a storage structure such as a rack, and configured to retrieve them.

[0003] To this end, ASRS systems include automated means of transport, which may include various technical solutions, such as motorized conveyors, in particular roller conveyors, elevators, lowerers, shuttles, stacker cranes, or even automated guided vehicles (AGVs), circulating along two horizontal dimensions of space, or even circulating along a third vertical dimension, these means of transport being configured to ensure the automated loading of the storage structure with containers which are mostly single-item, intended to serve as collection containers.

[0004] A single-item container is defined as a container that contains, within its volume, one or more structurally identical items, that is, items with identical sizes, shapes, and therefore structures. In some cases, containers may contain items that are structurally identical but not strictly identical, for example, structurally identical items of different colors. For the purposes of this disclosure, the contents of containers may refer to items that may or may not be structurally identical.

[0005] The containers used are part of the ASRS system and typically take the form of a bin, often made of plastic. These containers include various functions specifically adapted for their cooperation with the other elements of the ASRS, and in particular with the means of transport, or with the ASRS storage structure.

[0006] Thus, these specific functions can be, by way of example: - specific dimensions and functional surfaces for support in storage locations within the storage structure, for example for support on rack brackets, - a mechanical resistance suitable for withstanding a load without bending and thus without risk of falling, or even for withstanding such a load even in the event of water spray from a fire-fighting system - functional surfaces configured to be gripped by automated gripping systems, for automated loading / unloading, in storage locations, for example positive (protruding) or negative (recessed) reliefs intended to typically engage with male or female parts of a mechanized gripper, etc.

[0007] These storage and retrieval systems find particular application in the preparation of one or more orders. An order may include one item, or several identical items. However, an order is often composed of a combination of different items.

[0008] To this end, storage solutions typically include one or more order picking stations, either manual or automated. Such a manual order picking station may include an order picking station for one operator, typically with a digital interface, such as a screen displaying the contents of the current order. This interface allows the operator to pick one or more items from one or more typically single-item containers automatically transported from the storage facility to the station and manually place them into an order package, typically a shipping carton, at the station. The carton is opened for order assembly. The carton is then closed, typically by folding down top flaps, often in preparation for shipment or delivery.

[0009] The order station can itself be automated, namely including for this purpose an order preparation robot, typically a multi-axis arm equipped with a gripper, often a pneumatic suction cup system or a finger gripper, this robot being configured to automatically pick up one or more items from the container(s), often single-item, and place them in the order carton, at the order preparation station.

[0010] Regularly, and as orders are placed, the specific containers, typically single-item containers of the ASRS system, are emptied and the ASRS system storage system needs to be replenished with single-item containers, filled with said single-item containers.

[0011] To this end, the storage warehouses comprise, in addition to the storage structure of the ASRS system receiving the specific containers, serviced by automated transport means, for order preparation in an automated manner, a buffer storage area in which closed, typically single-item replenishment cartons are stored. Such a buffer storage area may itself be automated (or not).

[0012] When replenishment is necessary, a carton, often containing a single item, is removed from bulk storage and then opened, typically by deploying the carton's top flaps. The items from the single-item carton are then completely removed and loaded into one of the ASRS's specific, fully or partially empty containers at a replenishment station, in order to obtain a single-item container filled with the items. The replenished container is transported by ASRS vehicles to one of the ASRS storage locations. Prior art

[0013] In order to reduce the environmental footprint of order preparation operations, it is known, in such warehouses for ASRS system, to recover the replenishment carton, opened, emptied of items, which has allowed the filling of the empty ASRS container, and to transport it directly to one of the order preparation stations of the ASRS system, to serve as order packaging, and more specifically as an order / shipping carton, inside which the operator (or the robotic arm) places the item(s) of the order.

[0014] According to the inventors' findings, such a cardboard recycling operation, from the supply station to the order preparation station (or stations), requires adding additional conveyors to those already existing in the ASRS system, in order to transport the empty cartons directly from the supply station to one of the order preparation stations, bypassing the storage structure of the ASRS system, which in particular increases the floor space of the installation and its cost.

[0015] Such an order preparation process can be improved. Summary

[0050] [Fig. 10] is a detail view of [Fig.9]. Description of the implementation methods

[0051] This disclosure relates to an order preparation process implemented in an automated storage and retrieval system 1 comprising: - a GTP storage structure with storage locations, - at least one order preparation station for order picking, - C containers intended to receive CaP supply cartons and CaC order cartons.

[0052] The storage structure can be of different designs, and in particular.

[0053] According to a first design, the GTP storage structure may comprise one or more racks, which include storage locations, superimposed, the storage locations arranged at different height levels having lateral loading openings, allowing them to be loaded independently of each other, and as illustrated for example in the embodiments of Figures 8 and 9. Such racks typically comprise several columns of storage locations, superimposed, the different columns distributed along the length of the storage rack.

[0054] The racks can typically be arranged parallel to each other and separated by aisles. In such an embodiment, the containers are placed / removed from the storage locations in a substantially horizontal direction, the container typically supported by two mechanical interfaces attached to the uprights of the storage rack, and for example as taught in document WO2024056464. The depth of the storage locations allows for the support of a single container, or several containers, one behind the other.

[0055] According to a second design, the GTP storage structure allows for the definition of several juxtaposed storage columns, each configured to receive a stack of containers. These columns can be loaded and unloaded by automated guided vehicles (AGVs) traveling on a track or rails arranged above the storage columns. The AGVs include container gripping and lifting means, as taught in document FR 3,113,658 A1, enabling the top container of the stack to be grasped in one of the storage columns and lifted above the track or rails. The AGV includes motorized horizontal movement means to ensure its movement on a horizontal surface and to transport the container to an order preparation station, typically located at the edge of the storage structure.

[0056] Other storage structure designs are possible without departing from the scope of this disclosure, and for example that taught by document US2018 / 0148259.

[0057] The storage and retrieval system includes at least one order preparation station for order picking. Said at least one station order preparation typically includes one or more order preparation stations.

[0058] Said at least one order preparation station is arranged outside of the storage locations, for example laterally at a distance from said storage structure, typically on a warehouse floor.

[0059] At least one order preparation station may be manual. Such a manual order preparation station, 5a, may thus include an order preparation station for an operator, typically with a digital interface, typically a screen displaying the composition of the current order, and allowing the operator to pick one or more items, and to place them manually, in an order carton, intended for shipment, at the order station, the carton being opened for order assembly.

[0060] The control station 5b can itself be automated, namely comprising for this purpose an order picking robot, typically a multi-axis arm equipped with a gripper, often a pneumatic suction cup system, or even a finger gripper. Such an order picking robot is configured to automatically pick one or more items and place them in an order package at the order picking station.

[0061] Generally, the storage and retrieval system includes automated means of transport configured for transporting containers between said at least one order preparation station and the storage structure, and typically automated means of transport configured for transporting storage between said at least one order preparation station and an exit So of the storage and retrieval system.

[0062] Generally, particularly when the storage structure includes storage racks 2, the means of transport may include: - according to a first variant, a stacker crane arranged in particular in an aisle between two storage racks and configured to load / unload laterally the storage locations arranged according to the height and length of the storage racks, or typically automated conveyors configured to retrieve the containers unloaded by the stacker crane and transport them to the order preparation station, or a fleet of robots circulating on the ground, or on a runway, configured to retrieve the containers from the stacker crane and transport them to said at least one order preparation station, - according to a second variant, shuttles, circulating along the different heights of the storage locations along horizontal rails, the shuttles configured to unload / load the containers from the storage locations and transport them to a lowering / lifting system,configured to move containers vertically, transported by shuttles, and lowering them, or even raising them when containers are transported in the opposite direction, or typically automated conveyors configured to retrieve containers unloaded by the lowering system and transport them to the order preparation station, or a fleet of robots circulating on the ground, or on a treadmill, configured to retrieve containers from the stacker crane and transport them to said at least one order preparation station, - according to a third variant, first self-guided trolleys can be configured to travel on the ground up to the level of an aisle between two storage racks and second self-guided trolleys can be configured to move vertically and along the length of the racks to access storage locations, pick up a container, and then place it on one of the first trolleys, as taught by US20170267452A1. - according to a fourth variant, self-guided trolleys 3 each comprising horizontal movement means, such as motorized casters configured to move the self-guided trolley on a rolling surface such as the floor or a table, for example in the X and Y directions in [Fig.8], and climbing means comprising motorized toothed wheels configured to couple with climbing elements extending vertically along the height of the storage racks, typically attached to the uprights of the storage racks, and configured to permit vertical movement of the self-guided trolley up to a height level of a storage location.

[0063] According to this fourth variant, a gripping device comprises a support mounted movable relative to a chassis of said trolley between: - a deployed position, in which said support extends at least partially over a lateral edge of said trolley out of alignment with said chassis; and - a retracted position, in which said support is housed opposite said chassis.

[0064] In the deployed position, the movable support allows the container of said storage location to be lifted when the self-guided trolley is moved by the climbing means, before retracting the movable support to the retracted position, in order to unload a storage location. Conversely, loading a container into a storage location is carried out by deploying the movable support from the retracted position to the deployed position, then moving the self-guided trolley downwards until the container rests in said storage location, and as taught, for example, by document EP3638607A1.

[0065] According to the second design of the GTP storage structure comprising several storage columns, the means of transport comprising at least the self-guided trolleys traveling on tracks arranged above the columns of storage self-guided trolleys including means for gripping and lifting containers, and as taught by document FR 3.113.658 Al, or even elevator / de-lumber to raise / lower containers when said at least one order preparation station is arranged in the lower part of the storage structure.

[0066] Generally, a control unit, typically remote, which includes at least one microprocessor and a memory containing instruction sets, is configured to control the means of transport, and to allow the routing of containers in the storage and retrieval system, from the storage locations to said at least one order preparation station, or vice versa from said at least one order preparation station to the storage locations.

[0067] Said control unit can further be configured to control the means of transport, to convey the containers, from an ER input of the storage and retrieval system, for the purpose of loading the locations of the storage structure, or to convey the order cartons CaC, prepared at said order preparation station to an output So of the storage and retrieval system.

[0068] Generally, and when the means of transport include self-guided trolleys 3 circulating horizontally on a circulation area, on the ground or on a rolling table, the GTP storage structure, in particular the storage racks 2, the circulation area may include a peripheral safety barrier BR, prohibiting access to the circulation area by the operator, or a virtual safety barrier inactivating the storage and retrieval system, at least partially, when an operator crosses a detection beam of the virtual barrier.

[0069] In general, and as illustrated in [Fig.8]: - The ER entry of the storage and retrieval system includes a passage through the BR barrier, and / or, - the So exit of the storage and retrieval system includes a passage through the BR barrier.

[0070] Generally, self-guided vehicles are each equipped with a communication module, configured to receive and transmit data wirelessly to said remote computer control unit, and more particularly the communication module is configured to receive guidance instructions transmitted by the control unit.

[0071] Said remote control unit ensures the management and control of transport systems including the management of guidance trajectories of self-guided trolleys on a rolling surface, which can be the ground or a rolling table.

[0072] Said control unit typically comprises a database stored in memory, associating specific containers with contents. This database can be updated in real time, for example, when the container is replenished, when items are collected at said order preparation station, or more generally during an inventory step by an operator.

[0073] Such an update can be carried out by means of a user interface when the collection is manual, or during an inventory, or by means of a barcode reader, or automatically when the order preparation station is robotized by a vision or barcode reading system.

[0074] According to this disclosure, the process includes supplying the storage structure with Ai items from CaP supply cartons, each containing at least one Ai item.

[0075] CaP supply cartons are typically stored in a bulk storage facility, which is typically located in the same warehouse as the automated storage and retrieval system. The bulk storage facility may itself be automated (or not). The CaP supply cartons are preferably stored closed in the bulk storage facility and contain the items necessary to supply the containers of the retrieval storage system.

[0076] CaP supply cartons may be single-item, in whole or in part, each comprising one or more structurally identical Ai items.

[0077] Order cartons (CaCs) are the packaging used to group and ship the items of an order. In the context of automated storage and retrieval systems (ASRS), these cartons are often prepared at an order picking station, where items are picked from containers and placed in the order cartons, which are then typically sealed and often ready for shipment.

[0078] Containers C intended to receive CaP supply cartons and CaC order cartons are an integral part of the storage and retrieval system.

[0079] Containers C are part of the ASRS system and typically take the form of a bin, often made of plastic. These containers may include various functions specifically adapted for their cooperation with other elements of the ASRS, and in particular with the means of transport, or with the ASRS storage structure.

[0080] Thus, these specific functions can be, for example: - specific dimensions and functional surfaces for support in storage locations within the storage structure, for example for support on fixing interfaces such as rack brackets, - a mechanical resistance suitable for withstanding a load, without bending and thus without risk of falling, and even for withstanding water spray from a fire suppression system - Functional surfaces configured to be gripped by automated handling systems of transport equipment, for the purpose of automated loading / unloading, in storage locations, for example positive (protruding) or negative (recessed) reliefs intended to typically engage with male or female parts of a mechanized gripper

[0081] Containers C typically include a base and side edges (or side walls) configured for the lateral retention of the supply carton CaP or for the lateral retention of the order carton CaC

[0082] The order preparation process according to this disclosure includes: / A / Loading the supply cartons CaP, each onto a container C to form storage sets ES, / B / Transporting the storage sets ES to storage locations in the storage structure GTP, / C / Preparing orders at at least one order preparation station, comprising for all or part of the orders, picking at least one item Ai from at least one of the storage sets ES and placing said at least one item Ai picked into an order carton CaC.

[0083] Thus, / A / plans to load the supply cartons CaP onto the container C, which advantageously allows the ASRS to be supplied without requiring the emptying of the supply carton, and contrary to the practice known to the person skilled in the art described in the introduction for which the item(s) of the supply carton are transferred into a container, after opening the carton.

[0084] Loading the supply carton into the container according to / A / , typically operated at a PaP supply station, is advantageously carried out while preserving the contents, eliminates the need to empty the supply cartons before storage, thus simplifying the supply process compared to previous methods, and limiting human error.

[0085] Generally, said at least one supply station is typically distant from the GDP storage structure, typically on the periphery of the storage and withdrawal system 1, located outside the BAR barrier.

[0086] The supply carton can be kept closed during loading. The storage units, each comprising the container and the carton, are then transferred closed to the storage location of the structure.

[0087] In such a case, an inventory of the supply carton can be carried out when the carton is opened, typically at the order preparation station.

[0088] Generally, during an inventory, at the supply station or at least one order preparation station, the operator can enter the contents (items) of the carton using the user interface or by scanning a barcode in order to update the database. The interface allows, in particular, the operator to enter: - the type of item, - the number of items,

[0089] In general, loading closed supply cartons onto containers, according to / A / , and then transporting the ES storage sets to storage locations according to / B / , has several operational advantages.

[0090] First, this method reduces the number of additional handling steps required during supply, which results in a decrease in the processing time required to supply the GTP storage structure.

[0091] Indeed, thanks to this process, the opening of supply cartons can be deferred and carried out directly at at least one order preparation station. This saves time by limiting intermediate interventions and shifting this task to a more opportune moment in the logistics flow.

[0092] Furthermore, when the order preparation station 5a is equipped with several workstations dedicated to order preparation, it becomes possible to distribute the tasks of opening cartons among several operators. This distribution also allows for better management of inventory operations and the associated updates in the database.

[0093] Thus, each order preparation station can contribute to these updates, improving the overall efficiency of the process and reducing the risk of errors.

[0094] According to another possibility, the supply carton of said storage unit can be opened at the supply station and then transferred open to the storage location of the storage structure.

[0095] In such a case, an inventory of the supply carton can be carried out when the carton is opened, at the PaP supply station. During this inventory, the operator can enter the contents of the carton via a user interface in order to update the database.

[0096] The automated means of transport are configured for the transport of storage sets from the supply station to the storage locations of the GTP storage structure.

[0097] Generally, said supply cartons CaP include closing flaps Vf, configured to close a top opening of the carton, and which are initially closed. When opening the supply carton, particular care may be taken to open the carton without damaging the closing flaps, and in such a way as to allow for reuse of the supply carton.

[0098] Said storage assemblies, each comprising the container and said supply carton, can be configured to permit the opening of the closing flaps.

[0099] Generally, once the carton flaps are opened, the process may provide for keeping the closing flaps folded down against the side walls of the carton by adding a holding system.

[0100] Such a retention system may, for example, be specific to the container. For example, according to an embodiment illustrated non-limitingly in [Fig.3], the edges or side walls of the containers may be used to block the flaps Vf, each held in place between one of the edges (or side walls) of the container and one of the walls of the supply carton.

[0101] Such a retention system may be separate from the container, and for example include a tie, for example elastic, which encircles the flaps to lock them folded against the side walls of the carton.

[0102] Such a method of securing the shutters limits the risk of shutter interference, particularly during the transport of storage units. This method is advantageous during order picking in / C / to facilitate manual picking operations, or to ensure a clear field of vision inside the carton for a camera connected to the robotic arm of a robotic order picking station. Such a camera can be configured to recognize the contained items Ai for the purpose of picking them.

[0103] Transporting the ES storage assemblies according to / B / to storage locations of the GTP storage structure, is operated under the control of the control unit by automated transport means.

[0104] Preparing orders according to / C / audit at least one order preparation station, includes for all or part of the orders, picking at least one item Ai from at least one of the supply cartons CaP, opened, from the storage sets ES and placing said at least one item Ai picked into an order carton CaC.

[0105] During order preparation, picking items directly from the supply cartons in the storage sets and placing them in order cartons streamlines the workflow, allowing a smooth transition of items from sourcing to shipping. This reduces order processing time and improves the system's responsiveness to customer requests.

[0106] Depending on the number and nature of the items in the order, / C / may require one or more storage sets, and where appropriate several withdrawals of at least one item Ai from the supply cartons of the different storage sets.

[0107] For the purpose of order preparation according to / C / , the storage set(s) necessary for the preparation of an order, from which the item(s) Ai are collected, are transported prior to picking, from their storage location in the GTP storage structure and to said at least one order preparation station 5a, 5b.

[0108] The process can therefore provide between / B / and / C / : - / BC / transport the storage unit(s) from the storage location(s) to the order preparation station 5a, 5b, this transport being operated by automated transport means, under the control of the instructions of the control unit.

[0109] Notably, and according to the method set forth in this disclosure: / D / at least one CaP supply carton is emptied by said picking during one of the order preparations in / C / and in which the CaP supply carton emptied of said at least one item is used as said CaC order carton for at least one of the orders in / C / .

[0110] The use of emptied supply cartons as order cartons for subsequent shipments represents an effective recycling solution, reducing waste and costs associated with purchasing new cartons, while contributing to a smaller ecological footprint.

[0111] More particularly, such recycling can be carried out using the means of transport of the storage and retrieval system 1, already necessary for order preparation, already allowing the transport of the stored items between said storage structure GTP and said at least one order preparation station 5a, 5b, and therefore advantageously without requiring means of transport specific to such recycling, and contrary to the prior art described in the introduction which provides for the addition of a specific conveyor.

[0112] In certain circumstances, recycling CaP supply cartons into order cartons may not be sufficient to meet the carton requirements for all / C / orders. This insufficiency may be caused by several factors. For example, some cartons may degrade during handling, rendering them unsuitable for reuse.

[0113] Furthermore, the nature of recycled cardboard, particularly with regard to its dimensions and capacity, may not be suitable for all orders. Therefore, depending on the specific sizes of the orders to be processed, some recycled cardboard may not be usable, thus requiring a supplementary supply of new cardboard.

[0114] According to one embodiment, said loadings in / A / also include loading at least one container C with an empty item carton, not recycled from a supply carton, typically new, to form an empty storage unit ESO, and transporting said empty storage unit to one of the storage locations of the GTP storage structure. According to such an embodiment, at least one of the order cartons CaC in / C / is the empty item carton (not recycled from a supply carton) of said empty storage unit that was removed from said GTP storage location.

[0115] By loading containers with empty cartons of items to form empty storage sets, the process makes it possible to prepare order cartons ready for use in advance, thus optimizing the workflow, and for example to meet different useful volumes for orders.

[0116] Transporting these empty storage units to the storage locations ensures immediate availability of order cartons, reducing waiting time during order preparation. Such loading can also allow for the availability of different order cartons of varying sizes / capacities, stored in the storage structure on the containers.

[0117] During order preparation, the control unit can select, from among the different sizes / capacities of empty cartons intended to make up the order cartons, one of the cartons whose capacity is suitable for the volume of the items in the order. The control unit can, for example, estimate by calculation a total volume of the items in the order and select, from among the available empty cartons, the empty carton whose capacity is greater than the estimated total volume of the order, or close to the estimated total volume.

[0118] Generally, order cartons containing the items of orders in .C / are transported to the exit So of the storage and retrieval system by the system's means of transport, and under the instructions of the control unit.

[0119] Generally, and according to a first possibility, the supply carton(s) emptied in / D / at said order preparation station are used as order carton(s) CaC at said at least one order preparation station, and in particular without requiring temporary storage of the emptied cartons in the GTP storage structure.

[0120] According to a second possibility, a supply carton from an ES storage unit can be extracted from the GPT storage structure and emptied according to / D / and wherein the process comprises: / DA / a storage of the ES storage set comprising the container and the carton emptied of the items in the GTP storage structure and in which the supply carton used as the order carton in / D / is the carton of said storage set, emptied of the items, which was removed from said storage location after storage according to / DA / .

[0121] By extracting a carton from a storage unit and emptying it according to the process, the system allows the supply carton to be reused as an order carton, thus optimizing resource utilization. Temporary storage of the storage unit, including the container and the emptied carton, within the storage structure ensures efficient space and material management, reducing the need for new cartons, maximizing logistical efficiency, and maintaining the flexibility necessary to respond to variations in demand.

[0122] Thus, and generally, automated transport means can be configured for the transport of storage sets between said at least one order preparation station and the storage structure, and configured to: — transport, prior to one of the order preparations in / C / , at least one first storage set ES comprising the container C and the supply carton CaP containing said at least one item necessary for one of the orders from said storage location of the storage structure and to said at least one order preparation station and, — transport, prior to said order preparation in / C / , a second storage set comprising the container and an empty order carton (recycled from a supply carton or not), from said storage location of the storage structure and to said at least one order preparation station,and in which, during order preparation in / C / , said process includes at the order preparation station level: , - transfer said at least one item from said supply carton of said first storage set, and to the order carton of the second storage set or routed by the second set.

[0123] In general, the process may include, on the one hand, one of the order preparations according to / C / at the order preparation station 5a, 5b, and on the other hand, the finalization of said order: - transport and storage of the entire ES storage unit, including the CaC order carton containing at least one item from the order, in a storage location of the GTP storage structure, prior to transport of the entire storage unit containing the order carton to an exit So of said storage and retrieval system.

[0124] By transporting and storing the entire storage unit containing the order carton within the storage structure, the process allows for the efficient management of orders awaiting shipment. This intermediate step ensures that orders are organized and ready for shipment as soon as necessary, thereby optimizing workflow and reducing processing times. The temporary storage of order cartons improves resource management and space utilization, while ensuring fast and efficient shipment preparation.

[0125] In general; said automated means of transport can thus be configured to: - transport, after order preparation in / C / , said first storage set ES comprising container C and supply carton Cap from which said at least one item has been removed from order preparation station 5a, 5b, and to one of the storage locations of the storage structure GTP, and / or - transport said order carton CaC containing the order items to exit So of said storage and retrieval system 1.

[0126] According to one embodiment, the automated transport means comprise at least said fleet of self-guided trolleys 3 which are configured to transport: - the storage units each comprising the container and the supply carton and / or - at least one storage unit comprising the container and the order carton containing said at least one item from the order.

[0127] According to one embodiment, the transfer of at least one item Ai during one of the order preparations in / C / , at the order preparation station 5a, 5b, is carried out while the first storage set including said supply carton CaP is supported by a first self-guided trolley 3, and the second storage set including the order carton CaC is supported by a second self-guided trolley 3, the first trolley and the second trolley arranged in two adjacent parking positions facing an operator, or positioned within the field of action of a robotic arm of the order preparation station, and as illustrated by way of example in [Fig. 10].

[0128] According to one embodiment, the method comprises order completion, including the transport of said order carton CaC to an exit So of said storage and retrieval system 1 by one of the self-guided trolleys supporting a storage assembly comprising a container C and the order carton Cac containing said order. Said order carton Cac may be transported by the self-guided trolley 3 towards the exit, then the process involves separating the order carton CaC including the order of said container, then transporting the order carton separated from the container to the exit of the storage and retrieval system for example by a conveyor typically with rollers.

[0129] Other possible advantages of the process according to this disclosure are presented below.

[0130] According to one embodiment, at least one of the orders is a combination of items that is identical to the contents of the CAP supply carton of said ES storage unit; said method may provide / E / remove said storage set ES from said storage location and transport said supply carton CaP from said storage set directly to the exit So of the storage and retrieval system, constituting the order carton Cac.

[0131] Such a withdrawal of said ES storage unit and transport of the CaP supply carton according to / E / is carried out by automated means of transport, and possibly without passing through said at least one order preparation station, in particular when the means of transport include a fleet of automated guided vehicles 3.

[0132] In particular, when the Cap supply carton has been stored closed in the GTP storage structure, it is not necessary to open the carton for it to constitute the order carton. No picking is required, and its contents can be shipped as is.

[0133] By removing a storage set whose contents are identical to an order, the process allows the supply carton to be transported directly to the exit of the system, thus simplifying the order preparation process.

[0134] This method eliminates the need to transfer the items into a new order carton, thereby reducing processing time and costs associated with additional packaging.

[0135] According to another embodiment, at least one of the orders in / C / is a combination of items comprising a sub-combination of items, corresponding to the contents of the supply carton CaP of said storage set ES, from which one or more items may have been removed, and in which, during the / C / step: - said ES storage unit is removed from said storage location and transported to said at least one order preparation station 5a, 5b; - at least one second ES storage set comprising one or more items completing the item combination relative to the sub-combination, is removed from a from said storage locations and transported to the order preparation station, - at least one item is transferred from said at least a second storage set to said supply carton of said storage set containing the sub-combination until the combination of items is obtained, and then successively - said supply carton of said storage set containing the combination of item is transported, preferably after the carton has been closed, as an order carton to an exit of the storage and retrieval system.

[0136] Transport operations are carried out by automated means of transport, under the instructions of the control unit.

[0137] By allowing the preparation of orders comprising a sub-combination of items corresponding to the contents of a supply carton, the process optimizes the use of available resources.

[0138] Transferring items from a second storage set to complete the combination of items in the supply carton reduces the need for additional handling, thereby improving the efficiency of the order picking process.

[0139] This method allows for increased flexibility in inventory management, as it facilitates the assembly of complex orders while minimizing movements and associated costs.

[0140] According to another aspect, this disclosure relates to an assembly comprising an automated storage and retrieval system suitable for carrying out the process according to this disclosure and cartons containing one or more articles, said storage and retrieval system comprising: - C containers, - a GTP storage structure including storage locations for containers, - at least one order preparation station 5a, 5b located away from the storage structure, - automated transport systems configured for transporting containers between at least one order preparation station and the storage facility, and automated transport systems configured for transporting storage between at least one order preparation station and an exit of the storage and retrieval system

[0141] Said storage and retrieval system may in particular be that described in the context of the order preparation process. The GTP storage structure may be of different designs, and the means of transport automated of various kinds, as described previously. The means of transport are controlled under the instructions of the control unit.

[0142] According to one embodiment, the means of transport comprising in particular a fleet of self-guided trolleys 3.

[0143] The self-guided vehicles are each equipped with a communication module, configured to receive and transmit data with said remote computer control unit, wirelessly, and in which said remote control unit ensures the management and control of the means of transport including the management of the guidance trajectories of the self-guided vehicles on a rolling surface.

[0144] Said control unit may in particular have the functions which have been described in the context of the process.

[0145] According to said set according to this disclosure; a) the cartons containing the item(s) are received on the C containers forming ES storage units, b) the storage sets are stored in the storage locations of the GDP storage structure.

[0146] According to said assembly according to this disclosure; said control unit comprises one or more processors, memory and instruction set configured for the implementation of the order preparation process according to this disclosure.

[0147] In particular, the instructions are configured to order the means of transport, to recycle an emptied carton at said at least one order preparation station, as an order carton, at said order preparation station, for a subsequent order.

[0148] The storage sets preferably include containers, receiving single-item cartons containing several structurally identical items, from which samples can be taken during step / C / of the process.

[0149] The storage structure also receives storage units comprising containers, receiving cartons intended to serve as order cartons, open and empty of items. These may be cartons empty of items, having contained one or more items, which have been emptied at said order preparation station, or cartons, typically new, loaded empty at the supply station.

[0150] We describe an embodiment illustrated in [Fig.8].

[0151] The storage and retrieval system includes a storage structure comprising a plurality of two storage racks arranged parallel to each other and separated by aisles. The storage racks include braced uprights supported on a warehouse floor.

[0152] Each storage rack 2 comprises several stacked columns of storage locations, distributed along the length of the rack, the locations of Storage units are materialized by pairs of mechanical interfaces, such as brackets, attached to the uprights, with the two mechanical interfaces facing each other to support a container. The storage locations have lateral openings, allowing for loading and unloading.

[0153] The storage racks are serviced by a fleet of self-guided trolleys 3, each comprising means for horizontal movement, such as motorized casters configured to move the self-guided trolley on a rolling surface such as the floor or a table, for example in the X and Y directions, and climbing means typically comprising motorized gears configured to couple with climbing elements extending vertically along the height of the storage racks, typically attached to the uprights of the storage racks, and configured to allow vertical movement of the self-guided trolley up to a certain height level of a storage location. The climbing elements can typically be racks or roller chains, extending vertically and attached to the uprights of the storage racks.Each self-guided trolley includes a gripping device configured to load a container into one of the storage locations or, conversely, to unload it.

[0154] The gripping device comprises a support mounted movable relative to a chassis of said trolley between: - a deployed position, in which said support extends at least partially over a lateral edge of said trolley out of alignment with said chassis; and - a retracted position, in which said support is housed opposite said chassis.

[0155] In the deployed position, the movable support allows the container of said storage location to be lifted when the self-guided trolley 3 is moved by the climbing means, before retracting the movable support to the retracted position, in order to unload a storage location. Conversely, loading a container into a storage location is carried out by deploying the movable support from the retracted position to the deployed position, then moving the self-guided trolley downwards until the container rests in said storage location.

[0156] Thus, the self-guided carts 3 are configured to travel on the ground, within an area delimited by a physical barrier BR, and into one of the aisles between two storage racks, then couple to the storage rack, opposite one of the storage location columns, and then ascend to the level of the storage location to be serviced. The physical barrier BR prevents access to the cart traffic area by an operator during normal operation. Such a physical barrier has an access gate allowing access to the secure area for maintenance purposes.

[0157] A PaP supply station is located outside the secure area, and allows the implementation of step / A / of the process, namely a loading of a CaP supply carton containing one or more articles, typically structurally identical, onto a container C, forming a storage unit, said supply carton possibly remaining closed.

[0158] An input conveyor 6 is configured to automatically convey said storage assembly to a transfer device 7, which is configured to load said storage assembly onto one of the self-guided trolleys parked at the foot of the transfer device 7.

[0159] Said control unit communicates wirelessly with a communication module of the self-guided trolley supporting said storage assembly to ensure its movement on the ground to an aisle between two racks, then after coupling the toothed wheels with the climbing elements, commands a vertical movement of the self-guided trolley 3 to the height of one of the empty storage locations which is loaded by deployment of the mobile support.

[0160] Order picking stations 5a are arranged, in particular around the perimeter of the perimeter barrier in the case of manual order picking stations 5a where operators prepare orders outside the physical barrier BR. The system also includes automated / robotic order picking stations 5b.

[0161] As orders are received, the Cap supply cartons from the storage sets are emptied and can possibly be temporarily stored in the storage racks by the self-guided trolleys.

[0162] During the execution of an order, the control unit can select from the available empty cartons stored in the storage racks, one of the empty cartons whose capacity is suitable to contain the items of an order.

[0163] The control unit sends instructions to one of the self-guided trolleys 3 to transport said storage assembly including the selected empty carton from said storage location of the rack to the order picking station, for example the manual ordering station.

[0164] The operator retrieves the empty carton intended for recycling as an order carton by separating it from the container. The control unit then transports the storage set(s) containing the items from the storage structure to the order picking station, allowing the operator to pick the item(s) directly from the open supply cartons of the various sets and transfer them into the order carton (CaC).

[0165] Once the sampling is complete, the operator closes the carton by folding down the closing flaps Vf and then transfers the closed order carton CaC which is conveyed by an output conveyor to an output So of the storage and retrieval system 1.

[0166] The embodiment of [Fig.9] and 10 also includes storage racks 2 and self-guided trolleys, configured to move on the ground, and access storage locations to load and unload storage assemblies, similar to [Fig.8].

[0167] This embodiment is distinguished in that the transfer of at least one item during one of the order preparations in / C / , at the level of the order preparation station, is carried out while the first storage set including said supply carton CaP is supported by a first self-guided trolley 3a, and the second storage set including the order carton CaC, typically recycled, is supported by a second self-guided trolley 3b.

[0168] The first trolley 3a and the second trolley 3b are arranged in two adjacent parking positions, facing an operator, allowing the operator to pick an item from the supply carton CaP and place it in the order carton (not shown). The two parking positions can also be arranged within the reach of a robotic arm of the robotic order picking station 5b, as shown in [Fig. 10], so that the picking is performed by the robotic arm.

[0169] Once the order is finalized, the order carton can be closed, and said assembly including the container and closed order carton can be conveyed by the second trolley 5b to an exit of the storage and retrieval system.

[0170] In general, and as schematically illustrated in [Fig. 4], the process allows, in particular, for the successive: - load the storage units in / A / , the closed CaP supply cartons, according to step 1 in the GTP storage structure, - to open the CaC supply cartons from the storage units according to step 2, - to carry out an inventory and update the database and / or to pick items during order preparation according to step 3, - to close the order boxes, typically recycled, containing the items picked up, according to step 4, - to remove the closed order boxes from the order, which may have been temporarily stored in the storage structure.

[0171] Fig. 4bis is a detailed diagram of the picking of items from two ES storage sets comprising single-item CAP supply cartons, and their transfer into a set comprising a container and a CaC order carton, typically recycled. Benefits

[0172] In summary, the technical solutions described in this disclosure may provide some or all of the following benefits: - Supply optimization: Direct loading of supply cartons onto containers eliminates the need to empty cartons before storage, thus simplifying the process and reducing human error. - Logistical efficiency: Transporting storage assemblies to storage locations optimizes space utilization and improves operational efficiency, reducing the processing time required. - Streamlining workflow: Picking items directly from storage sets and placing them into order cartons allows for a smooth transition of items from procurement to shipping, reducing order processing time. - Effective recycling: Using empty supply cartons as order cartons reduces waste and the costs associated with purchasing new cartons, contributing to a smaller ecological footprint. - Flexibility and adaptability: The system allows for the efficient management of complex orders, facilitating the assembly of combinations of items while minimizing movements and associated costs. - Cost reduction: Automation and process optimization reduce operational costs and increase the system's ability to respond to variations in demand.

[0173] These advantages contribute to an overall improvement in the efficiency, sustainability and profitability of the automated storage and retrieval system. List of reference signs
