Definitions

  • the present invention relates to a packaging device and a method for producing packaging units according to the features of the independent claims.
  • beverage containers for example combining the items or containers into portable, relatively handy packaging units or packaging units.
  • beverage containers are usually combined and packaged using shrink film to form packs of four, six or more containers.
  • the production of packs is usually unavoidable, as they are the most common type of sales unit for beverage containers or bottles made of PET plastic.
  • the packs are sometimes combined again for transport and/or put together in layers and palletized.
  • One variant that basically does not require the use of shrink film is the so-called strapping pack.
  • the containers are combined into a pack and connected to one another using so-called strapping bands.
  • strapping machines that work continuously or intermittently, containers, articles or bottles are grouped into formations and then strapped with one or more bands using strapping units.
  • Typical formations can be, for example, 1 x 2 arrangements (two containers in a row), 2 x 2 arrangements (four containers in a square or in diamond formation), 3 x 2, 4 x 3 or basically variable nx m arrangements.
  • the object of the invention is to produce packaging units with an outer packaging made of paper or cardboard, in which preferably plastic-containing connecting elements can be completely dispensed with.
  • a packaging unit comprises an article arrangement of at least two articles, which are combined by at least one outer packaging.
  • the articles are held together mechanically by the outer packaging.
  • the outer packaging is preferably formed from an outer packaging material which is at least partially formed from paper material or cardboard material and partially envelops the article arrangement.
  • the outer packaging material is preferably a pure paper material or cardboard material which does not contain any plastic components, whereby packaging units can be produced in a particularly environmentally friendly manner.
  • the packaging device can also be used to process an outer packaging material with a plastic component, for example to process a plastic-coated paper material or cardboard material, a paper-plastic composite material or similar.
  • the outer packaging is a strapping band, preferably a paper band or a band made of a flexible, for example thin, cardboard material.
  • the articles are, for example, or preferably, beverage containers, in particular bottles made of PET or another suitable plastic, cans made of plastic and/or aluminum or similar.
  • the packaging device is also suitable for combining other suitable articles in appropriate outer packaging as packaging units or containers.
  • packaging units or containers Preferably, at least two identically designed articles are put together in a single-part module or similar as an article group and combined into sales units or packaging units using outer packaging. So-called mixed containers can be created by combining differently designed articles.
  • the packaging device comprises an application device for attaching the outer packaging material to the article arrangement and furthermore an ultrasonic joining device for forming a joint between at least two at least partially overlapping layers of the outer packaging material.
  • the ultrasonic joining device comprises at least one anvil tool and one sonotrode, wherein the anvil tool is designed to be at least partially inserted and arranged between at least two articles of the article arrangement partially wrapped by the outer packaging material, and wherein the sonotrode is designed to cooperate with the at least one anvil tool arranged at least partially between the articles to form a joining connection with the at least two at least partially overlapping layers of the outer packaging material.
  • the packaging unit particularly preferably comprises at least two beverage containers, in particular bottles or cans, which are preferably combined by at least one strap made of pure paper material.
  • the strapping band is applied to the article assembly via an application device designed as a strapping device or strapping module, which article assembly was previously assembled in the desired manner in a single-part module or similar.
