Definitions

  • the invention relates to a thermoforming packaging machine according to the preamble of claim 1, to a method for producing a multi-layer package according to claim 6 and 7 and to a multi-layer package with three product layers according to claim 9 and a multi-layer package with four product layers according to claim 12.
  • Thermoforming packaging machines type R535 from the house of the applicant are known. These can be equipped for the production of a multi-layer package with two product layers with separate workstations for cutting evacuation and gassing openings and for sealing evacuation and gassing openings in order to separately evacuate and / or treat both product layers.
  • the thermoforming packaging machine is expandable around a workstation for applying a corner cut.
  • thermoforming packaging machine for producing a multi-layer package comes from the DE 20 2005 015 901 U1 out.
  • a first product layer is placed on a first film web, fed to a second film web on the first product layer and a second product layer placed on the second film web. Together with another film web, all three films with the two product layers in between are fed to a sealing station.
  • both product layers are evacuated and / or gassed together and then all three film webs all sides circumferentially sealed together to form a package with two separate product layers and separated in a subsequent cutting station.
  • the second (central) film web is narrower than the first and third film web, so as not to cover the evacuation and gassing nozzles.
  • the disadvantage here is that the different product layers can not be specifically or differently evacuated and / or gassed.
  • a multi-layer pack with opening aids is in the DE 20 2010 009 454 U1 disclosed. All films are peelable sealed together and the packaging has at different corners opening aids to make the different product layers easily accessible. In this case, the films have a different peelability, so that it is easier to peel off the film for the upper product layer than the middle film for the lower product layer. There is no evidence for a packaging machine or to a manufacturing method of such a multi-layer package by means of a thermoforming packaging machine.
  • the object of the present invention is to improve a thermoforming packaging machine and a method for producing opening aids of a multi-layer package with different products with regard to the possibility of opening the various product layers.
  • thermoforming packaging machine with the features of claim 1, or by a method for producing a multi-layer package with the features of claim 6 or 7 and a package with three product layers with the features of claim 9 or a package with four product layers
  • the features of claim 12 are specified in the dependent claims.
  • the thermoforming packaging machine comprises a plurality of workstations for producing a multi-layer package.

  • One or more layers of cheese slices may also be packaged as a product layer.
  • a first workstation is a forming station for deep-drawing of troughs in a lower film web.
  • the sub-web is often a hard film, so that the deformation remains as a package in their form and the packaging provides a desired stability.
  • the bottom foil can also be a soft foil if the bottom foil web is to be applied to the product after evacuation.
  • the forming station is also suitable for cutting evacuation and / or gassing openings.
  • thermoforming packaging machine comprises a sealing station as a work station for evacuating and / or gassing and for sealing the lower film web and all other supplied upper film webs of the packaging together.
  • the thermoforming packaging machine according to the invention is characterized in that at least one intermediate work station, which is arranged in the production direction after the forming station and before the sealing station and provided for a format (ie is traversed by the packaging film webs in a single working cycle), both a Cutting device for at least one evacuation and / or gassing, as well as a Umsiegel worn for partially sealing at least one evacuation and / or gassing provides.
  • a cycle is defined as a work cycle in which a format (number of troughs transported per feed) is processed. After each cycle, during which the format is at a standstill, the format is forwarded by one feed rate to feed the format to the next following workstation.
  • the workstations usually have the dimensions of the formats that are transported at a feed, ie a length of up to 1200 mm.
  • thermoforming packaging machine In the case of a format of, for example, two wells or packs, a plurality of functions or working steps, such as resealing and / or cutting of evacuation and gassing openings as well as possibly even corner cuts or corner seals, are carried out in an intermediate workstation according to the invention.

  • the consumer can grasp a corner with two fingers, which is sealed together with all film webs as Eckenêtelung. This saves the consumer a fanning out of the films at a corner in order to deduct the desired film from the underlying.
  • the deep draw packaging machine has a number n-1 of intermediate work stations to reduce the machine length to the minimum.
  • the sealing station preferably has a tool upper part and a tool lower part in order to clamp all the film webs together on all sides airtight. This allows a separate and different evacuation and / or gassing each product layer.

  • a first product layer is inserted into the molded trough.
  • the lower film web with the first product layer is subsequently fed with a first upper film web into a first intermediate work station for punching an evacuation and / or gassing opening, for sealing off an evacuation and / or gassing opening and for cutting a corner through both film webs.
  • the lower film web with the first product layer and the first upper film web with the second product layer are subsequently fed with a second upper film web into a second intermediate work station for punching an evacuation and / or gassing opening, for resealing an evacuation and / or gassing opening and for sealing a corner and / or for cutting a corner through all three film webs.
  • the lower film web, the first upper film web with the first product layer, the second upper film web with the second product layer and a third upper film web are fed into a sealing station for evacuating and / or fumigating all product layers and for sealing the multi-layer package and for sealing at least one corner.
  • the packaging is separated from the film webs.
  • the film feed transports the films along the workstations. This includes the insertion stations for inserting the product layers.

  • several workstations the only one of the o.g. Perform functions, saved and reduced the machine length and the total cost of such a thermoforming packaging machine.
  • the inventive method for producing a package with four product layers which are separated by film webs analogously provides at least the steps which are provided in a multi-layer package with three product layers and additionally a further insertion path to insert a fourth product layer on the third upper film web.
  • a corner seal and a corner cut as well as a resealing of an evacuation and / or gassing opening are carried out.
  • the evacuation and / or gassing of all product layers and the sealing of the packaging and at least two corners, preferably three corners takes place.
