Definitions

  • the present invention relates to a packaging device and a method for packaging articles with the features of the respective independent claims.
  • Containers which may be formed by beverage bottles, beverage cans or the like, are frequently sold as packs, in which packs several containers are assembled and combined with the aid of a packaging material.
  • packaging material can be formed, for example, by strappings or by shrink film, whereby the containers of a respective pack are tightly held together as a finished sales unit.
  • bottle clips have existed for some time, which bottle clips are designed as flat packaging blanks, which bottle clips have an associated opening for each container of a respective pack and hold the respective containers of a respective pack together in a form-fitting manner.
  • a bottle clip can be applied to containers in different formation, thereby connecting the containers to form packs.
  • Such bottle clips are, for example, designed in the form of a perforated plate, as multi-connected lids or the like.
  • bottle clips perform an additional carrying handle function.
  • bottle clips are applied to the respective container group in a stand-alone machine.
  • the stand-alone, independent machine divides the packaging process and the associated machine areas.
  • Such machines require a lot of space if they are to be installed within a machine hall.
  • the application of the bottle clips usually takes place after the articles have been grouped. This interrupts the usual processing chain within the packaging machines. For the subsequent process, e.g. the closing of the outer carton or the wrapping of the grouped articles with a film packaging, the grouped articles must be brought once again into a defined machine division and fed into the machine for the application of the bottle clips. Only subsequently the carton can be closed or the wrapping with film can take place.
  • a malfunction may occur due to the numerous modules required to produce a pack.
  • DE 10 220 2009026A1 describes a method and a device for grouping and connecting articles, in which at least two articles are combined to form a packaging unit by the application of a first packaging material. In the course of a continuous conveying movement, the individual packaging units are joined together with an additional second packaging material to form a larger unit.
  • the invention relates to a method for combining several articles by at least one packaging material to form a pack.
  • the articles that are combined by the method to form a pack can, for example, be designed as beverage containers and in particular as beverage bottles and/or beverage cans.
  • an article group is formed from a plurality of articles to be combined into a respective pack, with at least one manipulator subsequently applying at least one packaging material to the respective article group and thereby combining the respective article group into a pack via the at least one applied packaging material.
  • the article group can be formed, for example, by initially moving articles in several parallel rows, whereafter articles intended for a respective article group are accelerated with respect to articles trailing behind, thereby creating a gap between the accelerated articles and trailing articles.
  • at least two conveyor belts can be provided, which conveyor belts adjoin one another in a direction of movement of the articles, wherein an upstream conveyor belt in the direction of movement of the articles is having a higher transport speed for articles than a downstream conveyor belt in the direction of movement of the articles and/or wherein a downstream conveyor belt in the direction of movement of the articles is being operated intermittently.
  • embodiments in which embodiments at least one retaining element is provided, which retaining element allows articles provided for a respective article group to pass and which retaining element temporarily delays further articles trailing these articles provided for the respective article group.
  • At least one supporting beam and/or pushing beam is brought into rear-side contact with the respective article group. Further, the application of the at least one packaging material takes place via the at least one manipulator while the respective at least one supporting beam and/or pushing beam is in rear-side contact with the respective article group with respect to the direction of movement of the respective article group.
  • the respective article group can be stabilized during the application of the at least one packaging material via the at least one supporting beam and/or pushing beam, which supporting beam and/or pushing beam is in contact with the rear side of the article group, so that the risk of an unintentional tilting of articles during an application of the at least one packaging material is kept small.
  • a pushing beam by using such a pushing beam, an exact position of the articles to be equipped with packaging material can be determined without having to use additional sensor devices, the signal assignment and signal processing of which is relatively costly and can lead to delays in the packaging process.
  • the movement of the supporting beam and/or pushing beam can be such, that a respective supporting beam and/or pushing beam is brought into contact with articles intended for a respective article group and then temporarily accelerates the articles of a respective article group, thereby distancing them from trailing articles.

  • An advantage preferably used in the present context which advantage is associated with a rear-side contact of the at least one supporting beam and/or pushing beam, is to be found in the fact that the respective position of the respective article group is known due to the rear-side contact of the supporting beam and/or pushing beam or corresponds exactly with a predetermined nominal position. This ensures with a high degree of certainty that the at least one packaging material can be applied to the respective article group without problems via the at least one manipulator.
  • a movement to be performed via the at least one manipulator for applying the respective packaging material to the respective article group can thus be coordinated in time with the respective actual position of the respective supporting beam and/or pushing beam, which supporting beam and/or pushing beam is in contact with the rear side of the respective article group with regard to a direction of movement of the article group.
