DETAILED DESCRIPTION
[0031] In
[0032] The packaging system 10a comprises two loading units 34a, which are configured to transfer respectively one packaging part 32a to the transport device 14a. The loading units 34a are in each case configured for transferring one of two different packaging parts 32a, which are in each case configured for a production of one of two different packaging types. The two loading units 34a are arranged side by side on the transport device 14a and are in each case configured to transfer the respective packaging parts 32a to respectively two of the movable platforms 30a in one point of the transfer device 14a. In particular, in a transfer to the transport device 14a, the packaging parts 32a are in each case laid upon two of the movable platforms 30a, such that the individual packaging parts 32a are preferably supported by the two platforms 30a. Alternatively, it is conceivable that the packaging parts 32a are in each case supported by only one movable platform 30a (see
[0033] The stator 26a of the transport device 14a has a closed effective surface 28a. Alternatively, it is also conceivable that the transport device 14a comprises more than one stator 26a and/or that the stator 26a comprises several effective surfaces 28a implemented separately from one another, wherein in the production by the packaging system 10a, in particular the packaging parts 32a, respectively the packagings 12a, are transferred from an effective surface 28a to another effective surface 28a by a transfer unit, for example conveyor belts, robot arms, suction cups or the like. It is conceivable that the packaging parts 32a, respectively the packagings 12a, are transferred with the platform/s 30a which transport the respective packaging part 32a, respectively the respective packaging 12a. The packaging system 10a comprises a control unit 36a, which is configured to control the movable platforms 30a via the stator 26a, respectively the planar drive, during a movement along the effective surface 28a. The control unit 36a is in particular configured to control the movable platforms 30a in such a way that packaging parts 32a/packagings 12a transported via the platforms 30a are moved along a designated production path 38a, 40a, 42a along the stator 26a, in particular along the effective surface 28a.
[0034] The packaging system 10a implements by the transport device 14a, in particular by the platforms 30a which are movable on the stator 26a, a plurality of production paths 38a, 40a, 42a. Preferentially, for a production of a packaging 12a and/or for a filling, the packaging parts 32a are respectively moved via the platforms 30a along one of the production paths 38a, 40a, 42a. The production paths 38a, 40a, 42a in each case extend over a different number of packaging stations 16a, 18a, 20a, 22a, respectively over different ones of the packaging stations 16a, 18a, 20a, 22a of the packaging system 10a. The packaging system 10a comprises a first packaging station 16a and a further first packaging station 16a′, which are in each case configured for folding packaging parts 32a when the packaging parts 32a are moved past them via the platforms 30a. The packaging parts 32a in each case have several pre-fold seams 44a (see
[0035] Downstream of the first packaging station 16a, respectively the further first packaging station 16a′, in particular viewed along the production paths 38a, 40a, 42a, the product feeds 24a of the packaging system 10a are arranged. Preferentially the product feeds 24a form a filling station 54a of the packaging system 10a. In particular, the platforms 30a are configured, during a transport after leaving the first packaging station 16a or the further first packaging station 16a′, to move the packaging parts 32a through one of the product feeds 24a. The packaging system 10a comprises three product feeds 24a, which are in particular arranged side by side at the transport device 14a. The product feeds 24a are in each case configured for filling a product into the processed packaging parts 32a, in particular while the packaging parts 32a are moved past or below them. The product feeds 24a are in each case configured to output a same product type. Alternatively, it is conceivable that different product feeds 24a are configured for filling the packaging parts 32a each with a different product type. Alternatively or additionally, it is conceivable that the packaging system 10a comprises only one product feed 24a (see
[0036] Downstream of the filling station 54a and/or of the product feeds 24a, in particular viewed along at least one of the production paths 38a, 40a, 42a, a second packaging station 18a is arranged. The second packaging station 18a comprises a tool 56a, which is realized as an exit opening and is implemented for outputting an adhesive material. Preferentially the second packaging station 18a, in particular the tool 56a of the second packaging station 18a, is configured, in a movement of the packaging parts 32a through the second packaging station 18a via the platforms 30a, to apply the adhesive material onto designated points of the packaging part 32a. The tool 56a of the second packaging station 18a is implemented at least substantially immobile, wherein in particular the packaging parts 32a are moved via the platforms 30a to the tool 56a with the points of the packaging parts 32a which are to be provided with the adhesive material, wherein in particular the packaging parts 32a respectively interact with the tool 56a of the second packaging station 18a. Alternatively it is conceivable that, instead of or in addition to gluing, packagings 12a are for example stuck together, riveted and/or clamped by means of the packaging system 10a.
[0037] The packaging system 10a comprises a third packaging station 20a, which is in particular configured for an inspection of processed and/or filled packaging parts 32a. The third packaging station 20a comprises a camera 58a for a registration of packaging parts 32a which are moved through the third packaging station 20a via movable platforms 30a. However, different implementations of the third packaging station 20a are also conceivable, for example with a scanner for a registration of an identifier marking on the packaging parts 32a, with a distance meter for a registration of outer dimensions of the individual packaging parts 32a, or the like. For example, the third packaging station 20a is configured for registering, in particular by means of the camera, a shape of the respective packaging part 32a, a filling level of the respective packaging part 32a, a quantity of the adhesive material and/or an area of the respective packaging part 32a that is covered in the adhesive material, or the like. In particular, only part of the production paths 38a, 40a, 42a of the packaging system 10a runs through the third packaging station 20a. It is conceivable that the transport device 14a is configured and/or actuated such that packaging parts 32a are moved via the platforms 30a from the first packaging station 16a or the further first packaging station 16a′, from the filling station 54a and/or from one of the product feeds 24a and/or from the second packaging station 18a to the third packaging station 20a, in particular directly. It is conceivable that a packaging part 32a is moved to the third packaging station 20a only at regular intervals, for example at predetermined time intervals and/or following a given number of processed packaging parts 32a. For example, it is conceivable that a packaging part 32a passes through the third packaging station 20a directly after a processing by the first packaging station 16a or the further first packaging station 16a′. Alternatively or additionally, it is conceivable that a packaging part 32a passes through the third packaging station 20a directly after a processing by the second packaging station 18a. Preferably the transport device 14a is configured to transport the packaging parts 32a via the platforms 30a, after passing through the third packaging station 20a, to one of the product feeds 24a, to the third packaging station 20a or to one of two fourth packaging stations 22a of the packaging system 10a, in particular depending on which stations of the packaging system 10a the respective packaging part 32a has already passed through before the third packaging station 20a.
[0038] The two fourth packaging stations 22a are arranged downstream of the second packaging station 18a and/or of the third packaging station 20a, in particular viewed along the respective production path 38a, 40a, 42a. The two fourth packaging stations 22a are realized so as to be substantially identical with regard to their construction. Alternatively, it is conceivable that the two fourth packaging stations 22a are in each case configured for a processing of one of the two different packaging types. The two fourth packaging stations 22a are in each case configured to close packaging parts 32a which move past via the platforms 30a by means of a tool 60a that is embodied as a slotted link, wherein in particular the packaging volume 52a is closed and/or at least a region of the respective packaging part 32a is pressed onto a point of the respective packaging part 32a that is covered in the adhesive material. The tools 60a of the two fourth packaging stations 22a are in each case implemented at least substantially immobile. Preferentially the two fourth packaging stations 22a, in particular the tools 60a of the two fourth packaging stations 22a, are in each case configured for processing the packaging parts 32a independently from the respective packaging type. The transport device 14a is configured for moving the platforms 30a, in a movement through one of the two fourth packaging stations 22a, depending on a packaging type assigned to the respective packaging part 32a, at different minimal distances from the stator 26, in particular the effective surface 28a of the stator 26a. In particular, the platforms 30a are implemented so as to be movable by the stator 26a transversally to the stator 26a, in particular the effective surface 28a. Preferably, for a closing of the packaging part 32a, the platforms 30a are configured, when passing through one of the fourth packaging stations 22a, respectively when moving past the tool 60a of one of the fourth packaging stations 22a, to be moved transversally to the effective surface 28a into a predetermined height relative to the tool 60a, depending on the packaging type of the packaging part 32a transported via the respective platforms 30a. It is conceivable that the packaging parts 32a move along the stator 26a via the platforms 30a in subregions of one of the production paths 38a, 40a, 42a with a different speed than in the remaining portion of the respective production path 38a, 40a, 42a. For example, the packaging parts 32a move via the platforms 30a, in a region of the two fourth packaging stations 22a, with a smaller speed than in a region before the two fourth packaging stations 22a, in particular in order to ensure a sufficiently long drying period for the adhesive material. Alternatively, it is conceivable that the platforms 30a with the packaging parts 32a move in subregions of the stator 26a faster or that they move over the entire stator 26a at a speed that remains substantially constant. In particular, the transport device 14a is configured to distribute the packaging parts 32a to the two fourth packaging stations 22a via the movable platforms 30a, wherein in particular a throughput of packaging parts 32a to be processed through the two fourth packaging stations 22a is substantially the same.
[0039] The packaging system 10a comprises two removal units 62a, which are configured for removing the completed, in particular processed and filled, packagings 12a from the transport device 14a, in particular from the platforms 30a. For example, the removal units 62a respectively comprise at least one gripper or sucker or clamp or a different gripping and/or removal element. Alternatively, it is conceivable that the removal units 62a are in each case embodied as a conveyor belt, wherein in particular the platforms 30a are configured, for example by a movement relative to each other, to push and/or drop the packagings 12a on one of the removal units 62a respectively. It is conceivable that the removal units 62a remove the packagings 12a and the respectively two platforms 30a transporting the individual packagings 12a together or separately from one another, the removed platforms 30a being preferably configured to be re-arranged on the stator 26a via one of the loading units 34a together with packaging parts 32a. Alternatively it is conceivable that, following the removal of the packagings 12a, the non-loaded platforms 30a are moved back to the loading units 34a via the stator 26a. It is conceivable that the stator 26a forms a re-conveying path (not shown in
[0040] The production paths 38a, 40a, 42a of the transport device 14a and/or the movement paths of the movable platforms 30a for a transport of the packaging parts 32a are preferably individually adjustable, in particular for the different packaging types, by means of the control unit 36a. Preferentially the individual movable platforms 30a of the transport device 14a are individually controllable by means of the control unit 36a. In particular, the control unit 36a is configured, in each case depending on a packaging type of the packaging part 32a transported via the respective platform 30a, to control the movable platforms 30a automatically and/or via a process parameter given by a user.
[0041] It is conceivable that one or several packaging station/s 16a, 18a, 20a, 22a of the packaging system 10a comprises/comprise movable tools for a processing of the packaging parts 32a, for example as a robot arm or as a pivoting arm, or on a robot arm or on a pivoting arm, or the like. It is conceivable that the platforms 30a comprise holding elements for fixing a packaging part 32a that is to be transported, for example at least one gripper or sucker, or via a negative pressure at the support surface 33a, or the like. In addition, implementations of the transport device 14a are conceivable in which the packaging parts 32a are transported while suspended from the platforms 30a. Generally, further implementations of the packaging system 10a are also conceivable, for example implementations having a different number and/or sequence and/or different embodiments of packaging stations 16a, 18a, 20a, 22a, product feeds 24a and/or production paths 38a, 40a, 42a (see for example
[0042] In
[0043] In a method step 102a of the method 100a, the packaging parts 32a are transferred to the transport device 14a via the two loading units 34a, and are in particular in each case laid upon two of the movable platforms 30a, in particular upon the support surfaces 33a of the movable platforms 30a. For producing one of the packaging types, the movable platforms 30a of the transport device 14a are in each case moved, depending on a type of the packaging part 32a transported via the respective platform 30a, on a predetermined production path 38a, 40a, 42a assigned to the respective packaging type (see
[0044] In a further method step 104a of the method 100a, the packaging parts 32a are conveyed by means of the transport device 14a having a planar drive, wherein the packaging parts 32a are in each case moved via two of the platforms 30a of the transport device 14a which are movable by means of the planar drive, and are processed during a movement induced by the platform 30a. The processing steps, carried out via the packaging stations 16a, 18a, 20a, 22a for a production of the packagings 12a from the packaging parts 32a, are in each case realized at least partly by a force induced by the movable platforms 30a. During a transport via the movable platforms 30a, for executing several processing steps for a production of a packaging, the packaging parts 32a successively pass through at least part of the packaging stations 16a, 18a, 20a, 22a of the packaging system 10a.
[0045] In a further method step 106a of the 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 a packaging type that is to be produced from the respective packaging part 32a. For producing the packagings 12a, in a method step of the method 100a, in particular the method step 106a, the packaging parts 32a, transported in each case via two movable platforms 30a, are in each case folded during a movement by means of the tools 50a of one of the first packaging stations 16a, 16a′. In particular, in a folding of the packaging parts 32a, in each case the packaging volume 52a is formed from walls 46a, 48a of the individual packaging parts 32a. In a method step of the method 100a, in particular the method step 106a, a processing step is executed for producing the packagings 12a from the packaging parts 32a, in particular for folding, by a direct interaction of the packaging parts 32a, which in each case move via two movable platforms 30a, with the tools 50a of one of the first packaging stations 16a, 16a′, which are implemented at least substantially immobile relative to the movable platform 30a. Preferably the packaging parts 32a, implemented as carton blanks, are erected by one of the first packaging stations 16a, 16a′.
[0046] In a further method step 108a of the method 100a, the packaging parts 32a are moved to one of the product feeds 24a via the movable platforms 30a. In a method step of the method 100a, in particular the method step 108a, products are put into the processed, in particular folded, packaging parts 32a, in particular into the packaging volumes 52a, during a transport by the transport device 14a, wherein the movable platform 30a actuates a product feed 24a of the plurality of product feeds 24a of the transport device 14a, depending on an availability of products at the respective product feed 14a.
[0047] In a further method step 110a of the method 100a, during a movement of the packaging parts 32a which are in each case transported via two of the movable platforms 30a, the adhesive material is applied onto the individual packaging parts 32a by the tool 54a of the second packaging station 18a for a production of the packagings 12a. In a method step of the method 100a, in particular the method step 110a, a processing step, in particular the application of the adhesive material, for producing the packagings 12a from the packaging parts 32a is brought about by two movable platforms 30a moving relative to each other. In a method step of the method 100a, in particular the method step 110a, the packaging parts 32a, transported in each case via two movable platforms 30a, are rotated around at least one axis by a relative movement of the movable platforms 30a for a production of the packagings 12a, in particular for an application of the adhesive material.
[0048] In a further method step 112a of the method 100a, individual packaging parts 32a are moved through the third packaging station 20a, wherein in particular those points of the packaging parts 32a are checked which were provided with the adhesive material. Alternatively or additionally, it is conceivable that individual packaging parts 32a are moved through the third packaging station 20a after folding, after filling and/or after closing, in particular for the purpose of checking a shape of the processed packaging part 32a, a filling quantity and/or a gluing point of the processed and/or filled packaging part 32a and/or of a closure region of the produced packaging 12a. In a method step of the method 100a, in particular the method step 112a, for checking a previously executed processing step, at regular intervals a portion of the transported packaging parts 32a is deflected onto a different production path 40a, 42a, which in particular comprises the third packaging station 20a. It is thus conceivable that the method step 112a is carried out at a different stage of the method 100a, for example following one of the method steps 102a, 104a, 106a, 108a. Preferably, at the third packaging station 20a, the packaging parts 32a are rotated around at least one axis by a relative movement of the two movable platforms 30a transporting the respective packaging part 32a for the purpose of checking, in particular via the camera 58a, in particular for a complete registration of the packaging part 32a that is to be checked. It is conceivable that for an evaluation, the data captured via the camera 58a for checking the packaging parts 32a are processed by means of a computing unit and/or control unit of the third packaging station 20a and/or by means of the control unit 36a. If deficiencies are detected in the checking process, it is conceivable that the respective packaging part 32a is removed from the transport device 14a and/or further packaging parts 32a are checked.
[0049] In a further method step 114a of the method 100a, the packaging parts 32a are moved via the movable platforms 30a through one of the two fourth packaging stations 22a for closing and/or producing the filled packagings 12a. Preferentially the packaging parts 32a are closed by means of the tool 60a of one of the fourth packaging stations 22a. In particular, the packaging parts 32a directly interact with one of the tools 60a of one of the fourth packaging stations 22a for closing, wherein during a movement via the movable platforms 30a relative to the respective tool 60a, the packaging parts 32a are subjected to a force by means of the respective tool 60a by moving and approaching via the platforms 30a. In a method step of the method 100a, in particular the method step 114a, for a transport of the packaging parts 32a and for closing the packaging parts 32, the movable platforms 30a are in each case moved in a direction that is oriented transversally to the stator 26a of the transport device 14a for a processing step, in particular for closing, in particular depending on the respective packaging type, wherein the packaging part 32a transported via the respective platform 30a is at least partly deformed in the processing step. Preferentially the packaging parts 32a are lifted or lowered via the platforms 30a to a predetermined height relative to the tool 60a, such that the tool 60a is appropriate for a closing of the respective packaging type.
[0050] In a further method step 116a of the method 100a, the finished, in particular closed and filled, packagings 12a are removed, for example lifted, slid or pushed, from the movable platforms 30a by means of the removal units 62a.

The third packaging station 22b is configured for closing packaging parts 32b, which move past the third packaging station 22b via the platforms 30b, by means of a tool 60b that is implemented as a slotted link, wherein in particular a packaging volume 52b is closed and/or at least one region of the respective packaging part 32b is pressed onto a point of the respective packaging part 32b that is covered in the adhesive material. The tool 60b of the third packaging station 22b is implemented at least substantially immobile. The third packaging station 22b, in particular the tool 60b of the third packaging station 22b, is configured for processing the packaging parts 32b independently from a course of their production path 38b, 40b. It is conceivable that the transport device 14b is configured to move the packaging parts 32b along the stator 26b via the platforms 30b at different speeds in different subregions of a production path 38b, 40b. For example, it is conceivable that the transport device 14b is configured to move the packaging parts 32b for a registration by the camera 58b in the second packaging station 20b at a lower speed than, for example, in a region between the product feed 24b and the first packaging station 18b, or in particular to shortly stop the packaging parts 32b completely. Alternatively or additionally, it is conceivable that the transport device 14b is configured to move the packaging parts 32b through the third packaging station 22b during or after closing, for the purpose of allowing the adhesive material to dry, at a lower speed than, for example, in a region between the first packaging station 18b, respectively the second packaging station 20b, and the third packaging station 22b. The transport device 14b is configured to move the finished, in particular closed and filled, packagings 12b via the movable platforms 30b downstream of the third packaging station 22b to the removal unit 62b.
