Definitions

  • the invention relates to a packaging machine, in particular for food products, with a plurality of along a transport direction successively arranged workstations for producing multi-layer packages of a lower film, a top film and at least one intermediate middle film, the lower film with the middle film a lower product layer and the top film with or a further middle film includes an upper product layer of a respective package, the films each having a product region and edge regions extending laterally next to the product region parallel to the transport direction.
  • the invention also relates to a method for producing such multi-layer packages.
  • the invention relates to uses of certain films in such a packaging machine and / or in such a method.
  • the invention relates to a multi-layer package which is produced or producible by such a packaging machine and / or which is obtained or obtainable by such a method.
  • multi-layer packs for example for packaging food products
  • at least two products lie one above the other, wherein in each case two product layers lying directly above one another are separated from one another by a middle foil.
  • the center foils are also sometimes as intermediate foils or - as well as the top Foil of the pack - called top films.
  • all of the films lying between the lowermost film (the lower film) and the uppermost film (the upper film) are referred to as a middle film, respectively.
  • edge regions of the films can be provided with holes through which the product layers are accessible to evacuate the product layers and filled with a protective gas.
  • gas exchange is often preferred in practice, but in principle not mandatory. In some applications it is sufficient to only evacuate the product layers before final sealing. If gas exchange is desired, evacuation and gassing can be sequential, for example via the same perforations. Usually, however, different holes are used for evacuation and gassing. In general, it is in practice - especially for hygienic reasons - therefore preferred to perform the evacuation and gassing on different flow paths, It is e.g.
  • the products forming the lower product layer are placed on the product region of the lower film, which is supplied to the machine on the input side. Downstream of the product tray, the center sheet is fed, enclosing the lower product sheet.
  • the middle film is often fixed to the lower film in order to ensure a correct relative position between the middle film and the lower film during further transport in the packaging machine. This fixing is usually done by so-called sealing, in which the middle film and the lower film are stapled together by forming sealing points.
  • sealing is not yet a gas-tight end seal, but serves - as mentioned - only a fixation of the two films together.
  • the products forming the upper product layer are placed on the middle foil, namely at those points where the first product layer was previously applied.
  • further product layers and middle films can be applied in order to produce multi-layer packages with more than two superimposed product layers.
  • this working length which is also referred to as the preferred length or format length, is usually n times the length of a package, if appropriate plus waste in each case between two immediately consecutive packages, where n is the number of successive packages in the transport direction in a respective format.
  • the upper film After applying the single upper product layer or the last of several upper product layers, the upper film is supplied, so that the upper or uppermost product layer is included.
  • the at least three film webs with the enclosed product layers then pass into the already mentioned sealing station in which the product layers are subjected to vacuum and / or gas through the perforations present in the edge regions of the films and are finally sealed.
  • the lower film must be reshaped to form shell-like packaging bases.
  • the lower film must pass through a so-called thermoforming station of the packaging machine.
  • each middle sheet is narrower than the lower sheet and than the upper sheet, so that the perforations of the lower sheet are not overlapped by the middle sheet.
  • a punching of the center foils is not required by this.
  • a comparatively simple sealing, as mentioned above, is not possible since the center foils each have no sufficiently wide edge region for this purpose.
  • all product layers must be evacuated and / or gassed via the holes formed in the lower film. An advantageous in many cases individual treatment of the product layers during evacuation and / or gassing, each with a direct access to the relevant product location, is then not possible.
  • the packaging machine described evacuating and / or gassing again exclusively via perforations of the lower film, the middle films each overlap with their edge regions, the edge regions and thus the perforations of the lower film.
  • the center foils are also perforated here, with the resulting openings each having to be provided with a seal in order to ensure a gas-tight passage through the foils involved in each case.
  • a work station is a sealing station which is designed to apply vacuum and / or gas to the product layers through perforations present in the edge regions of the upper film and the lower film and then to seal them by sealing the films, the sealing station engaging upper evacuation and / or gassing tool aligned with the top film perforation and a lower evacuation and / or gassing tool aligned with the bottom film perforation, wherein another work station is an annealing station located upstream of the sealing station and adapted to abut the center film to seal the bottom foil at a sealing located in the edge areas, and wherein the lower evacuation and / or gassing of the sealing station and a serving for the preparation of the sealing sealing tool of the sealing station on a common, parallel to the transport direction g running working line lie.
  • the packaging machine is designed to produce a seal during operation on overlapping edge regions of films transported in the transport direction and to cooperate with a perforation, wherein the sealing and the perforation at the same transverse position, ie on a common, parallel to the transport direction extending line or within a running parallel to the transport direction strip whose width is not greater than the width of the edge regions.
  • This embodiment of the packaging machine according to the invention does not exclude a common or independent adjustability of the tools transversely to the transport direction for other applications.
  • the product layers are subjected to vacuum and / or gas through perforations present in the edge regions of the upper film and the lower film and then sealed by sealing the films, wherein the application of vacuum and / or gas takes place while the non-perforated edge region of the Middle film and the perforated edge regions of the lower film and the upper film overlap each other, and wherein the lower product layer is applied through the perforation of the lower film and the upper product layer through the perforation of the upper film.
  • the edge region of the middle film may overlap the edge regions of the lower film and the upper film and need not be perforated when the sealing station of the packaging machine is designed to pass the upper product layer through the upper film and the lower product layer through the lower film to act on.
  • a workstation for punching the middle foil can thus be saved.
  • the packaging machine can therefore be shortened by at least one working length and thus cycle length.
  • a further simplification of the packaging machine results from the fact that no Umsiegelonne must be formed on the perforations of the lower film and the upper film, since the perforation of the lower film only access to the lower product layer and the perforation of the upper film only has to gain access to the upper product position.
  • the ability of the sealing station according to the invention, to apply the superimposed films both from below and from above for evacuation and / or gassing increases the cost of construction and operation of the sealing station and the packaging machine as a whole, however, only seemingly. Because the lower tool and the upper tool can each be simpler in construction and operated as a sealing station, which must be able to act on several superimposed product layers from a single page. In addition, the sealing station according to the invention does not need to have expensive additional measures, such as devices for producing perforated seals, which are required when direct access to the individual product layers is required from a single side.
  • the overlapping of the edge regions of the lower film and the upper film by the unperforated edge regions of the middle film also has the further advantage that the middle film is simply fixed by sealing to the lower film and thus a correct alignment of the middle film and lower film can be ensured relative to each other. This makes it possible to use the edge region of the lower film both for evacuating and / or gassing of the lower product layer and for sealing the middle film to the lower film.
  • the edge regions need only be as wide as is required for either the perforation or the seal, if according to the packaging machine according to the invention, the lower evacuation and / or gassing of the sealing station and the sealing tool of the sealing station are aligned with each other transversely to the transport direction, ie lie on a common, parallel to the transport direction working line. It has been recognized that the perforation of the lower film and the sealing can be formed in such a way that neither the evacuation and / or gassing process, nor the production of the sealing or the fixing function of the sealing are impaired.
  • the middle film need not be wider or narrower than the lower film.
  • the advantage of the invention is that not only the middle film and the lower film but also all the film webs can at least have substantially the same web width. For the operator of the packaging machine, this simplifies procurement and storage of the individual films considerably.
  • the invention therefore also relates to the use of a non-apertured film as the center film in a packaging machine of the type disclosed herein and / or in a method of the type disclosed herein.
  • the invention further relates to a use of at least three films of at least substantially the same web width as the bottom film, top film and center film in a packaging machine of the type disclosed herein and / or in a process of the type disclosed herein.
  • the lower evacuation and / or gassing tool and the sealing tool in Transport direction do not overlap each other. Both tools can therefore be comparatively short, namely shorter than a pack length. This allows a further reduction in the length of the packaging machine.
  • the tools can also be arranged in the transport direction relative to one another in such a way that, relative to a respective package, a sealing area and a perforated area overlap one another in the transport direction.
  • the sealing region and the perforation region can each extend over the entire package length or at least over a substantial part of the package length.
  • the perforation and the seal do not interfere with each other, for example, be provided that in the transport direction alternately a gas passage of the perforation and a Ansiegelstelle follow the seal succession.
  • at least substantially the entire package length and thus the entire, moreover comparatively narrow edge portions of lower film and middle film can be used both for the perforation and for the sealing.
  • the packaging machine is cyclically operable, wherein in a respective cycle, the films are movable in the transport direction by a working length corresponding to at least one package length.
  • sealing tool each have a length in the transport direction, the sum of which is smaller than the working length.
  • the functions of the sealing station namely the evacuation and / or gassing on the one hand and the final closure by sealing, on the other hand, are often in a single common one Tool united, ie one speaks in this case not of different tools.
  • this embodiment means that an evacuation and / or gassing area is provided on the common tool, which does not extend over the entire working length of the tool.
  • the upper evacuation and / or gassing tool also lies on the common working line.
  • the structure of the sealing station can be further simplified thereby.
  • the upper evacuation and / or gassing tool and the sealing tool overlap one another in the transport direction.
  • the separation of the lower packing layer and the upper packing layer with respect to the application of vacuum and / or gas thus makes it possible to variably select the position of the upper evacuation and / or gassing tool with respect to the sealing tool for sealing the middle film to the lower film in the transporting direction. Because the seal between the middle film and lower film on the one hand and the perforation of the upper film on the other hand do not affect each other.
  • the lower evacuation and / or gassing tool, on the one hand, and the evacuation and / or gassing tool, on the other hand do not overlap one another in the transport direction.
  • Such a staggered in the transport direction arrangement of the tools may be for certain applications and / or in view of a simpler structure and / or operation of the sealing station and thus the packaging machine advantage.
  • an edge region of the lower film and the upper film overlapping middle film is particularly advantageous if the product layers are not in molded recesses should or should be, but if it is sufficient or desired to pack the products between two unformed film webs. Therefore, according to a preferred embodiment, it may be provided that the packaging machine has no thermoforming or forming station for producing transformations in one or more of the films. The packaging machine can thereby be further simplified and shortened.
  • the lower product layer and the upper product layer are simultaneously exposed to vacuum and / or gas.
  • the application of vacuum and / or gas on the one hand and the closing on the other hand in a one of the work stations forming sealing station is preferably, the application of vacuum and / or gas on the one hand and the closing on the other hand in a one of the work stations forming sealing station.
  • the edge region of the middle film is sealed to the edge region of the lower film.
  • a fixing of lower film and middle film to each other can in principle be done in other ways.
  • the sealing takes place along a working line extending parallel to the transport direction, on which at least the perforation of the lower film, preferably also the perforation of the upper film, lies.
  • the lower film and the upper film are not simultaneously and / or at different, in particular in the transport direction spaced apart, punched locations of the packaging machine.
  • the structure of the packaging machine can thereby be made more flexible.
  • the lower film and / or the upper film are perforated during feeding.
  • a workstation performing the punching operation inside the machine frame of the packaging machine.
  • a tool for punching the respective film outside the machine frame and in particular in the feed path of the film.
  • a space to be supplied anyway for feeding the respective film can thus be used at the same time for perforating the film.
  • the perforation of the lower film and the punching of the upper film need not necessarily be integrated into the operation of the packaging machine. Rather, it is also possible according to the invention to use a pre-punched lower foil and / or a pre-punched upper foil, ie foils which are already perforated during their manufacture and are used in the already perforated state by the operator of the packaging machine.
  • the lower film and the upper film are perforated in such a way or correspondingly pre-perforated films are used, that in a respective package the perforations of the lower film and the upper film do not overlap one another in the transport direction.
  • the perforations each have one or more gas passages, which are each formed either by material removal or without material removal caused by cutting, slitting or perforation of the material, preferably additionally by exhibiting one or more material sections.
  • the formation of the gas passages without material removal has the advantage that no disturbing material snippets arise.
  • the lower film, the upper film and the middle film each have the same web width.
  • a deep-drawing or shaping process for producing forming operations can not be carried out on any of the films.
  • the application of vacuum and / or gas and the sealing takes place respectively on both sides of the product area, in particular simultaneously and / or in the same way.
