Definitions

  • a method for packaging cuboid objects is known.
  • the article is pushed together with a section of a wrapping material film through upper and lower folding elements into an intermediate station, so that the film envelops the article in a U-shape.
  • the protruding edge of the U-web is first folded down onto the front of the product, then an overlapped longitudinal seam is formed with the free legs, and finally the edge opposite the U-web is folded onto the front.
  • the product is pushed out, the two remaining edges are folded overlapping on the end faces and glued. It is therefore a package folding that does not allow hermetic closure.
  • a method for packaging cuboid cheese pieces is known. First, a film section is folded and sealed on the opposite side edges. These sealed edges form fin seams on the front sides of the packaged product. The product is filled into the formed bag and finally the packaging is completed by an overlapped longitudinal seam and by folding down the corners protruding from the end faces. This type of packaging is also leaky and is not suitable for packaging biscuit groups.
  • a packaging for biscuit groups which has a longitudinal fin seam and two transverse fin seams.
  • the transverse fin seams extend over the flat side of the biscuits. If a tear strip is attached to this packaging, the package is divided into two parts after tearing, in which the biscuits lie parallel to the opening and are therefore difficult to remove from which they are made.
  • the invention has for its object to provide a method for packaging disc-shaped objects, in which the packaging produced with it does not have the above disadvantages. This object is achieved by the invention defined in the claim.
  • the fin seams namely the two end fins 11, 12 and 21, 22 and the longitudinal fin 13, 23 are at least approximately in a common plane, at least on the inside of the packaging.
  • the objects G are directed with their end faces against the end fins 11, 12 and 21, 22, and the flat side is directed against the longitudinal seam 13, 23. If, as usual, the tear-open aid, such as a tear-open strip 24, is arranged perpendicular to the longitudinal seam 23 in FIG. 2, it can easily be seen that after the opening part 25 has been removed, the objects G protrude from the packaging 20 within easy reach.
  • the packaging 10 can also be provided with a similar tear strip.
  • the objects G are encased in an orderly manner on three sides with a section of flexible wrapping material, for example a transparent film.
  • the longitudinal seam 13 is then formed on the long side.
  • the items G are thus held in such a way that this semi-finished packaging can be transported further into a sealing station for the formation of the gusset folds 14, 15 and subsequent sealing of the transverse seams 11, 12 without the items having to be held in their position by means of retractable and extendable holders .
  • the transverse seams 21, 22 are fastened to the end wall in the packaging 20. This can be done by applying an adhesive.
  • the adhesive can be applied in the form of discrete dots or as a glue line.
  • the packaging machine shown schematically in FIG. 3 is intended to provide groups of objects G with a wrapping film.
  • the objects G are lifted into an input station A by means of a vertical plunger 32 and lie there with the flat side perpendicular to the plane of the plunger 32.
  • This station is located in front of a wrapping film 33 which is cut off from a film web 35 by knives 34.
  • Known stationary folding elements 36, 37 are arranged behind the wrapping film 33, through which the wrapping film 33 is placed in a U-shape around the objects G when the latter is moved between the folding elements by means of the plunger 39 and the plunger support 39a, which moves along the rail 38 36, 37 through estossen g and get into the intermediate station B.
  • a feed member 41 can be moved horizontally back and forth.
  • This has a buffer bar 41 b made of soft material as a counter-holder for the objects G, a transport bar 41 a for later transportation and a folding element 41 c at each end to form the gusset folds 14, 15 (FIG. 1).
  • the intermediate station B is as a chamber formed, which has a bottom 42 and an upper support 43 which is connected to a lever arm 44. This is attached to an axle pin 45 in order to convey the partially packaged objects at most in a second way. At the top of the carrier 43 there are leaf springs 43a in order to hold the objects G in the chamber.
  • the gusset folds 14, 15 are formed by the folding members 41c, 48.
  • the wrapped articles G are transferred to a conveyor belt 49 in order to be passed on to a station (not shown) for forming the transverse seams 21, 22.
  • the arrangement of the objects G in the packaging according to FIGS. 1 and 2 has advantages in that the device for folding the film 33 around the objects G and the devices for forming the seams can be made much simpler than is otherwise the case, for example, in the case of an arrangement according to CH-A 574 852, which should be the case.
