[0001] Processes for producing packaging have already been proposed, for example, using a packer, top loader, carton erector, tray erector, or lidder. Typically, multiple processing lines are required for preparing and closing the packaging. Additional processing steps, such as inspection, gluing, etc., require additional processing lines. This requires large, interconnected transport systems and / or packaging systems, each of which must be configured for a specific packaging type to be produced.

[0003] Furthermore, transport systems with linear drives are already known from EP 3 265 305 B1, GB 2 561 826 A, US 2016 / 244273 A1, WO 2021 / 019007 A1 and US 2003 / 136086 A1.GB 2 561 826 A, WO 2021 / 019007 A1 and US 2003 / 136086 A1 basically disclose a method and a packaging system for producing packaging, wherein in at least one method step packaging parts are conveyed by means of a transport device, wherein the packaging parts are each moved over at least one platform of the transport device which can be moved by means of the drive and are processed during a movement caused by the platform, wherein the platform is held in a close region of the stator by means of a magnetic force which acts between a stator of the transport device and the platform, wherein at least one processing step for producing a packaging from a packaging part is carried out at least partially by a force caused by the at least one movable platform.

[0004] The object of the invention is to enable the production of packaging with all necessary processing steps on a single flexible processing line. Disclosure of the invention

[0005] A method for producing packaging, in particular cartons, is proposed, wherein in at least one method step packaging parts, in particular carton parts, are conveyed by means of a transport device with a planar drive, wherein the packaging parts are each moved via at least one platform of the transport device that can be moved by means of the planar drive and are processed during a movement caused by the platform, wherein the platform is held in a close region of the stator by a magnetic force that acts between a stator of the transport device and the platform, wherein the platform is freely moved along a maximum effective surface of the stator independently of fixed paths, wherein at least one processing step for producing a packaging from a packaging part is carried out at least partially by a force caused by the at least one movable platform.

[0006] Preferably, the platforms of the transport device are moved along a stator of the transport device for transporting the packaging parts / packaging via a combination of a magnetic force and an air flow applied to the platforms, wherein the platforms move at a distance from the stator. In particular, the platforms are held in close proximity to the stator via the magnetic force, which acts in particular between the stator and the individual platforms. Preferably, the platforms are each moved along the stator via a force based on the reluctance principle, wherein in particular the platforms are each subjected to a reluctance force via a magnetic resistance on the stator that changes in an area surrounding the platforms. In particular, the platforms can each be moved freely along a maximum effective surface of the stator, independently of fixed paths.In particular, when the platforms move along the stator, there is no frictional force between the stator and the individual platforms. In particular, the platforms are subjected to a force through the active surface via the stator.

[0007] Preferably, the individual packaging parts / packages are transported during transport by means of the transport device, in particular regionally and / or temporarily, by one platform, two platforms and / or several platforms. Preferably, the packaging parts / packages are supported on the platforms and / or held by the platforms, for example clamped. Alternatively or additionally, it is conceivable for the packaging parts / packages to be held on the platforms by holding means, for example suction cups, clamping devices or the like. It is conceivable for the packaging parts / packages to stand on the platforms or hang from the platforms during transport by means of the transport device. Preferably, the packaging parts are subjected to the force in at least one method step during a movement caused by the platform(s) transporting the respective packaging part.

[0008] To produce the packaging, the packaging parts are preferably moved by means of the transport device along at least one production path, which preferably runs along the stator, in particular at least substantially parallel to the active surface of the stator. It is conceivable that the at least one production path is dynamically adapted during transport of a packaging part depending on at least one or more process parameters, for example a type of packaging to be produced, a packaging part to be transported via the platform(s), a product type to be filled into the packaging, or the like, wherein in particular the respective platform(s) are moved over a different path via the stator.

[0009] The transport device is preferably part of a packaging system which is provided for producing the packaging and for filling the produced packaging. The produced packaging is preferably filled / loaded, in particular with products, during transport via the platforms of the transport device. In particular, filling / loading of the packaging / packaging parts takes place during or after production of the packaging during transport via the transport device by means of at least one product feed of the packaging system. Particularly preferably, the packaging is produced from packaging parts during transport by means of the transport device, in particular the platforms, and is filled / loaded with products during or after transport by means of the transport device, in particular the platforms.Preferably, the packaging parts are moved during transport by means of the transport device over the platforms to at least one packaging station of the packaging system, wherein in particular the packaging parts are processed to produce the packaging. The at least one packaging station comprises at least one tool for processing the packaging parts, preferably during a relative movement of the respective packaging part to be processed, which is transported over a platform, and the tool. Particularly preferably, the packaging parts are processed during transport over one or more platforms of the transport system to produce the packaging. Particularly preferably, the produced packaging is filled / loaded during transport over one or more platforms of the transport system.It is also conceivable that the packaging is filled / loaded during production, whereby in particular production of the packaging is completed after filling / loading.

[0010] For example, the packaging parts are designed as cardboard blanks, as plastic elements, as wooden components, or the like. It is conceivable that the packaging parts are pre-processed during transport by means of the transport device, for example, cut to size, coated, and / or glued. Alternatively or additionally, it is conceivable that the packaging parts are checked and / or inspected during transport by means of the transport device, in particular to ensure a sufficiently high quality of the packaging parts before or during production of the packaging. Alternatively or additionally, it is conceivable that the produced packaging is checked and / or inspected during transport by means of the transport device, for example before filling / loading or before closing.Preferably, at at least one point of the packaging system, in particular the transport device, a transfer of the packaging parts and / or blanks of the packaging parts to the transport device, in particular to one or more platforms of the transport device, preferably by means of a user and / or by means of a feed unit.

[0011] The inventive design of the method enables advantageously flexible and modular packaging production through a single processing line. In particular, the required movements of the packaging parts can be carried out at least largely or exclusively via the platforms, which advantageously enables simple and cost-effective designs of packaging stations on the transport device.

[0012] Furthermore, it is proposed that in at least one method step, a packaging part passes through a plurality of packaging stations one after the other while being conveyed over a movable platform for carrying out processing steps for producing a packaging. This can advantageously enable an compact processing line. An advantageously simple and cost-effective design of the individual packaging stations can be enabled, in particular since these are controlled directly via the platforms. Preferably, the packaging part(s) are processed during transport over a platform. It is conceivable that the packaging part is temporarily stopped for processing at at least one of the packaging stations. Preferably, the packaging part is processed in each of the packaging stations using at least one tool.Preferably, the packaging part is moved / processed sequentially during transport by means of the platform over a plurality of packaging stations of a plurality of packaging stations of the packaging system. Preferably, in at least one method step, a plurality of packaging stations of the packaging system to be controlled is selected for each packaging part, in particular depending on the process parameter, the availability of the individual packaging stations, a number of the packaging part in a series of packaging parts, for example, for regular inspection of packaging parts or manufactured packaging, or the like. Preferably, the transport device is controlled for individual control of the individual platforms by means of a control unit of the packaging system.In particular, in order to produce the packaging, the individual or at least some of the packaging stations, in particular the tools, preferably the driven and / or controllable tools, are controlled by means of the control unit.

[0013] It is also proposed that, in at least one method step, at least one processing step for producing a packaging from a packaging part is carried out by at least two movable platforms moving relative to one another. Additional devices and / or tools for carrying out the respective processing step, for example for rotating, lifting, or the like, the packaging / packaging parts can advantageously be omitted. This makes it possible to create an advantageously compact and cost-effective processing line. It is conceivable for a packaging part to be transported by at least two platforms moving at least essentially synchronously along the stator. In particular, the packaging part rests on the at least two platforms simultaneously for transport and / or processing or is clamped by the at least two platforms.Preferably, the packaging part is processed, for example folded, deformed, rotated, or the like, in at least one, in particular the, method step by the at least two movable platforms moving relative to one another. In addition, it is conceivable that the packaging part is processed, for example folded, deformed, rotated, or the like, in at least one, in particular the, method step by interaction with a tool and a simultaneous relative movement of the at least two movable platforms. It is conceivable that the at least two platforms are moved relative to one another within a plane that is aligned, in particular at least substantially parallel to the active surface of the stator, and / or viewed along the active surface of the stator at least substantially perpendicular to the active surface of the stator.

[0014] It is further proposed that, in at least one method step, at least one processing step for producing a package from a packaging part takes place through direct interaction of the packaging part moving over a movable platform with a tool that is at least substantially immobile relative to the movable platform. This enables an advantageously simple and cost-effective design of the individual packaging stations, in particular since the packaging parts can be moved exclusively over the platforms. In particular, the tool that is at least substantially immobile relative to the movable platform is designed as a dispensing means, for example a nozzle or other opening, for dispensing an adhesive, or as a link, as an edge, or the like.Alternatively or additionally, it is conceivable that in at least one method step at least one filling / loading of a packaging part / a packaging takes place during transport via a movable platform, in particular during or between a movement, via a tool which is at least substantially immobile relative to the movable platform and which is designed in particular as a filling tool, for example a closable opening, as an exit of a conveyor belt, as a detachable gripper or suction cup or the like, for filling / loading the packaging parts or packages. The packaging part is preferably machined during the machining step. To carry out the machining step, the packaging part preferably interacts with the tool in a force-fitting and / or form-fitting manner. For example, at least part of the packaging part is formed by interaction with the tool, in particular as a link, as an edge or the like.The tool, designed in this way, is moved relative to the remaining part of the packaging part, for example folded, bent and / or shifted. For example, during the processing step, the packaging part is coated and / or provided with an adhesive via the tool, which is designed in particular as a dispensing means. "Substantially immovable" is to be understood in particular as a design of a tool, wherein a processing region of the tool, for example a contact surface of the tool for interacting with a packaging part, a dispensing opening for applying an adhesive to a packaging part and / or a dispensing opening for dispensing a product for filling / loading the packaging parts / packages, is designed to be immovable relative to the stator, in particular the active surface of the stator, during the process for producing the packaging.In particular, it is conceivable for an at least substantially immovable tool to comprise movable and / or driven components, for example for cutting or partially folding packaging parts, wherein a processing area formed by the tool or the components is immovable relative to the stator, in particular the active surface of the stator, during the method for producing the packaging. Alternatively, it is also conceivable for the packaging system to comprise packaging stations and / or tools that are movable, in particular driven, relative to the stator, in particular the active surface of the stator, and whose position is preferably changed at least temporarily during the method, in particular by means of the computing unit.

[0015] Furthermore, it is proposed that, in at least one method step, an adhesive be applied to the packaging part via the tool during a movement of a packaging part transported over one or more movable platforms to produce a package. This enables an advantageously simple and flexible production of packaging with adhesive joints. Movable tools for applying the adhesive can preferably be dispensed with, particularly since the packaging parts are moved over the platforms.Preferably, in a further method step, during a movement of the packaging part transported over one or more movable platforms for producing a package, at least one region of the packaging part provided with the adhesive is connected, preferably by means of a further tool of the packaging system, to another part of the packaging part and / or to a further packaging part, for example by folding, bending, attaching or the like. Alternatively or additionally, it is conceivable that in at least one method step, a packaging part is riveted, clamped and / or stapled during a movement or transport over one or more movable platforms for producing a package by means of at least one tool of the packaging system to connect individual regions of the packaging to be produced.

[0016] It is also proposed that, in at least one method step, a packaging part transported over one or more movable platforms is folded during a movement to produce a package. This can enable advantageous, simple and flexible production of more complex packages. An additional movable tool for folding the packaging parts can advantageously be omitted. Preferably, when folding a packaging part, at least one wall of the packaging part is moved relative to at least one further wall of the packaging part, in particular about a common axis, wherein the at least one wall and the at least one further wall are preferably formed in one piece. In particular, the at least one wall and / or the at least one further wall are / is moved, in particular in each case, by interaction with at least one tool.It is conceivable that the at least one wall is supported by means of the platform(s) and the at least one further wall is moved relative to the at least one wall by means of the at least one tool. Alternatively or additionally, in particular in another method step, it is conceivable that the packaging part is supported by the platform, wherein the at least one wall interacts with at least one tool and the at least one further wall interacts with at least one further tool to fold the packaging part, wherein preferably the at least one wall and the at least one further wall are moved relative to one another and in particular relative to the platform. In particular, the tool(s) for interacting with the at least one wall and / or the at least one further wall or for folding the packaging parts are designed as links, edges or the like.formed, wherein in particular the packaging parts, in particular the at least one wall and / or the at least one further wall, interact with the tools via a movement generated by the movable platforms. In particular, the tool(s) for interacting with the at least one wall and / or the at least one further wall or for folding the packaging parts are designed to be at least substantially immobile relative to the movable platforms. Preferably, in at least one method step, in particular before the packaging part is transferred to the transport device or in a preceding processing step during transport by means of the transport device, at least one pre-fold seam is introduced into the packaging parts, wherein folding of the packaging part takes place at the at least one pre-fold seam during the movement over the platform(s).

[0017] It is further proposed that, in at least one method step, a packaging part transported across multiple movable platforms is rotated about at least one axis by a relative movement of the movable platforms to produce a package. This advantageously allows for a high degree of freedom when moving the packaging parts across the platforms.

[0018] Preferably, the packaging part is rotated by the relative movement about an axis oriented at least substantially perpendicular and / or at least substantially parallel to the active surface of the stator. Alternatively or additionally, it is conceivable for the packaging part to be rotated by the relative movement about an axis oriented obliquely to the active surface of the stator. For example, in at least one method step, packaging parts are rotated for inspecting the packaging parts, preferably after a processing step, wherein, in particular, the packaging parts can be inspected independently of a movable sensor, such as a camera or the like.Alternatively or additionally, it is conceivable that in at least one method step, packaging parts are rotated to apply adhesive to the individual packaging parts, preferably relative to a tool, in particular one that is at least substantially immovable, by which the adhesive is dispensed. Alternatively or additionally, it is conceivable that in at least one method step, packaging parts are rotated to fold the packaging parts relative to a tool designed as a link or edge, in particular one that is at least substantially immovable, wherein in particular regions of the individual packaging parts can be moved over a larger folding angle compared to packaging parts that are only moved translationally during folding.Preferably, the packaging parts are rotated about the axis by at least 90°, preferably at least 140°, and particularly preferably at least 180° in at least one method step by means of at least one platform or by a relative movement of several movable platforms. It is also conceivable for the packaging parts to be rotated in space about more than one axis in at least one method step by means of at least one platform or by a relative movement of several movable platforms. For example, the packaging parts / packaging are rotated for the purpose of detecting a surface and / or a wall of the individual packaging parts in the method step and / or a further method step. It is conceivable for the packaging parts to be rotated for the purpose of detecting an identifier, for example a barcode, QR code, or the like, and / or glued and / or otherwise coated surfaces of the packaging parts.For example, the packaging parts are rotated in such a way that a printed / coated side of the packaging parts faces a camera and / or another detection element in a further process step, for example when passing through a further packaging station.

[0019] Furthermore, it is proposed that the packaging parts are transported by means of the transport device along one of at least two different possible predetermined production lines, wherein in at least one method step, packaging parts are guided, in particular at regular intervals, to a different production line for inspection of a processing step on a movable platform instead of via one of the production lines. Advantageously, different movement routes of packaging and / or packaging parts during production can be enabled in a simple and flexible manner, for example for inspection of individual processing steps carried out and / or of produced packaging. Advantageously, different processing lines for different production methods and / or different types of packaging to be produced can be enabled simultaneously and via a single transport device.In particular, the various production lines run over a different number of packaging stations and / or product feeds and / or through different packaging stations and / or product feeds of the packaging system. Preferably, the processing unit assigns one of the various production lines to each packaging part depending on the process parameters of the respective packaging part. Preferably, the platform(s) transporting the respective packaging part are controlled such that the packaging part moves along the production line assigned to the respective packaging part.For example, after a processing step, packaging parts are transported at regular intervals, for example, one packaging part every 3 minutes and / or every tenth packaging part, to another production line, which in particular comprises a packaging station for inspecting the packaging parts, preferably to monitor the quality of the processing step. Alternatively or additionally, it is conceivable for packages and / or packaging parts to be filled / loaded with one product from a plurality of different products and / or with a different number of products, wherein in particular the production lines each comprise or run through one of several different product feeds.It is conceivable that the various production lines are specified by a user and / or an external unit and stored in the control unit or are determined by means of the control unit as a function of the process parameters of the individual packaging parts / packaging, of a position or a design of the individual packaging stations and / or the individual product feeds and / or of at least one process parameter specified by the user, such as a maximum packaging time for producing and filling the packaging, an inspection rate of the individual processing steps or the like.It is conceivable that predetermined production lines are adapted by means of the control unit depending on the process parameters of the individual packaging parts / packages, on a position or a configuration of the individual packaging stations and / or the individual product feeds and / or on at least one process parameter specified by the user, such as a maximum packaging time for producing and filling the packaging, an inspection rate of the individual processing steps or the like, in particular during the process.

[0020] It is also proposed that, in at least one method step, products are introduced into packaging or packaging parts during transport via the transport device, wherein at least one movable platform controls a product feed of a plurality of product feeds depending on the availability of products at the respective product feed. This enables advantageously flexible, situation-dependent filling of the packaging on a packaging production line. Preferably, production of the packaging and filling of the packaging can be enabled via a single processing line. In particular, the individual product feeds of the plurality of product feeds are each arranged on one of the different production lines.It is conceivable that different products are dispensed via the individual product feeds of the plurality of product feeds, or that the same product is dispensed. In particular, the availability of the product dispensed at the respective product feed is transmitted to the control unit via the product feeds, wherein, in particular, the control unit controls the movable platforms to move to a product feed loaded with products or to be loaded with products at the earliest possible time.

[0021] It is further proposed that in at least one method step, a plurality of different packaging types are produced at least substantially simultaneously by means of the transport device, wherein the movable platforms of the transport device are each moved depending on a type of packaging part transported over the respective platform for producing one of the packaging types on a predetermined production line assigned to the respective packaging type. An advantageously large number of different packaging types can be produced simultaneously via a single processing line / transport device. Advantageously, demand-optimized production of packaging can be achieved, in particular depending on a product type and / or a size of products to be packaged, which can in particular be provided on the transport device.It is conceivable that a packaging type of a packaging part to be transported is recognized and / or predetermined when the packaging part / the blank of the packaging part is transferred to the packaging system and / or is detected by means of a sensor unit or the like of the packaging system. In particular, a packaging type is assigned to each of the individual movable platforms, which in particular corresponds to the packaging type of a packaging part transported via the respective platform. Preferably, a production line is assigned to each of the individual packaging types to be produced and / or a production line is determined for each of the individual packaging types to be produced. In particular, the various production lines are designed differently from one another perpendicular to the active surface of the stator.Alternatively or additionally, it is conceivable for the various production lines in at least one region of the stator to have a different minimum distance from the stator, in particular the active surface, wherein in particular the platforms are moved at a different height along the stator. For example, it is conceivable for packaging parts to be moved past a tool via the platforms at a first height to the stator for producing a first packaging type, wherein in particular a wall of the packaging parts is folded, and for packaging parts to be moved past the tool via the platforms at a second height to the stator, which is in particular greater or smaller than the first height, wherein in particular a wall of the packaging parts is folded.In particular, packaging parts for producing the first packaging type and packaging parts for producing the second packaging type have a different size.

[0022] Furthermore, it is proposed that in at least one method step, at least one movable platform is moved in a direction oriented transversely to a stator, in particular the aforementioned stator, of the transport device for transporting a packaging part for a processing step for producing a packaging, wherein the packaging part is at least partially deformed during the processing step and, in particular, the minimum distance between the stator and the platform is increased. Advantageously, processing steps can be enabled wherein the packaging parts can be moved and / or processed at least partially in space, in particular out of a transport plane. An advantageously high degree of freedom can be achieved when moving the packaging parts across the platforms.In particular, the movable platform is moved transversely to the active surface of the stator for the processing step, preferably away from the stator, in particular away from the active surface of the stator. The movement of the movable platform transversely to the stator in a region of the stator preferably occurs by increasing the flow of air through the active surface and / or weakening the magnetic field in the region of the stator, which is regulated in particular by means of the control unit. For example, a packaging part transported via two movable platforms is deformed or folded in a processing step by a movement of one of the two movable platforms transversely to the stator, in particular relative to the other movable platform, wherein in particular one wall rests against the platform and another wall rests against the other wall.Alternatively or additionally, it is conceivable that by means of a movement of a platform transverse to the stator in interaction with a tool, the tabs and / or walls of the packaging part are plugged together.

[0023] In addition, a packaging system for carrying out a method according to the invention for producing packaging is proposed, comprising at least one transport device with a planar drive, which comprises at least one platform movable by means of the planar drive, wherein the platform is held in a close range of the stator by a magnetic force acting between a stator of the transport device and the platform, wherein the platform is freely movable along a maximum active surface of the stator independently of fixed paths. The transport device preferably comprises a plurality of movable platforms and at least one stator, in particular the aforementioned stator. The movable platforms are preferably designed to be controllably movable via the stator independently of one another along the stator, in particular the active surface. The packaging system preferably comprises the control unit.The packaging system preferably comprises at least one packaging station and at least one product feed. It is conceivable for the packaging system to comprise a plurality of packaging stations and / or a plurality of product feeds. The control unit is preferably configured to control the movable platforms independently of one another via the stator in a movement along the stator. In particular, the control unit is configured to use the magnetic field generated in a region close to the active surface of the stator and / or the flow of... Airto be controlled and / or regulated by the active surface of the stator. Preferably, the packaging station(s) and / or the product feed(s) of the packaging system are each arranged at least in a close region of the transport device, in particular of the stator, preferably at least partially on or at an outer side of the stator having the active surface. In particular, the close region of the transport device, in particular of the stator, extends within a minimum distance oriented perpendicular to the active surface of at most 1 m, preferably at most 80 cm and particularly preferably at most 50 cm. In particular, the minimum distance depends on the size of the packaging to be produced. It is conceivable that the packaging station(s) and / or the product feed(s) of the packaging system are each arranged, in particular fastened, on the transport device, or are set up separately from the transport device.

[0024] The inventive design of the packaging system enables advantageously flexible and modular packaging production. In particular, the required movements of the packaging parts can be carried out at least largely or exclusively via platforms of the transport device, which advantageously enables simple and cost-effective designs of packaging stations on the transport device. This advantageously enables low manufacturing costs for the packaging system.

[0043] In a further method step 106a of method 100a, the packaging parts 32a are moved through one of the first packaging stations 16a, 16a', in particular the first packaging station 16a or the further first packaging station 16a', in particular depending on the type of packaging to be produced from the respective packaging part 32a. In a method step of method 100a, in particular method step 106a, the packaging parts 32a, each transported via two movable platforms 30a, are folded during a movement using the tools 50a of one of the first packaging stations 16a, 16a' to produce the packagings 12a. In particular, when folding the packaging parts 32a, the packaging volume 52a is formed from walls 46a, 48a of the individual packaging parts 32a.In a method step of method 100a, in particular method step 106a, a processing step for producing the packaging 12a from the packaging parts 32a, in particular folding, takes place through a direct interaction of the packaging parts 32a, each moving on two movable platforms 30a, with the tools 50a of one of the first packaging stations 16a, 16a', which are designed to be at least substantially immovable relative to the movable platform 30a.
