Definitions

  • the present invention relates to an arrangement according to the preamble of claim 1 and to a method for packaging a single, small article, preferably a candy, and a device for packaging the article.
  • FIG. 5 shows an arrangement according to the prior art. Shown is a packaged item. The article is packed by means of a packaging film. At the two ends of the packaging film rotary envelopes 104, 105 are formed. This is why we also speak of a "double-twist". Through each of the rotary envelopes 104, 105 a Drehfähnchen 106, 107 is formed. Between the two rotary envelopes 104, 105, a longitudinal seam 108 is formed. In each case, another seam 114 is located on the twist stops 104, 105 or on the rotary lugs 106, 107. In the prior art, the longitudinal seam 108 is partially sealed with cold seal adhesive.
  • the other seams 114 are also usually sealed with cold seal adhesive. This results in no tight packaging. Even with the use of a cold seal adhesive on the longitudinal seam 108 and on the other seams 114, only a conditionally tight package is produced due to the mini capillary action in the rotary flag area.
  • the arrangement, the method and the device according to the independent claims make it possible to save packaging film.
  • This is achieved by ultrasonically sealing the longitudinal seam.
  • the use of ultrasonically sealed longitudinal seams in combination with the double twist wrapping enables extremely fast and cost-effective production while at the same time saving packaging film.
  • the use of ultrasound technology makes it possible to pack the article in an absolutely tight package.
  • a first Drehfähnchen is formed.
  • a second Drehfähnchen is formed.
  • At least one further seam for connecting at least two layers of the packaging film is preferably located on the rotary flag and / or on the twist stops. Particularly preferably, the further seam is located at the outermost point of the rotary flag. The further seam can be sealed both by means of cold seal adhesive and by means of ultrasound.
  • the seam is particularly preferably applied to the outermost region of the rotary flag.
  • the further seam is in the area of the twist stops.
  • the cold seal adhesive is applied before forming the twist stops. Only during the twisting thus the further seam is closed.
  • the cold seal adhesive is already applied to the film roll (endless belt). A first closing of the seam happens already when closing the rotary fingers. The final suture closure is then achieved by twisting.
  • the invention further includes a method of packaging a single, small article, preferably a candy.
  • the advantageous embodiments and subclaims described in connection with the arrangement according to the invention accordingly find advantageous application to the method according to the invention.
  • the method comprises the following steps: (i) wrapping the article with packaging film. This wrapping happens in a so-called "form shoe", which puts the film in the direction of running around the article. (ii) inserting two layers of the packaging film between an ultrasonic sonotrode and a counter tool. (iii) applying an ultrasonic vibration to the ultrasonic sonotrode to form an ultrasonically sealed longitudinal seam, and (iv) forming a first twist wrap and a second spin wrap on the packaging film.
  • the sequence of method steps described above is adhered to.
  • the packaging film can be inserted much more accurately between the ultrasonic sonotrode and the counter tool before forming the twist stops.
  • the ultrasonically sealed longitudinal seam can thus be formed over the entire length of the packaging material. Advantages for forming an exact longitudinal seam provides the hose formation.
  • a further seam is formed on the twist stops or on the rotary flag.
  • this further seam is formed during the formation of the twist stops.
  • an ultrasonic seal is used for the other seams.
  • the other seams are also sealed in time prior to the formation of the twist envelopes with ultrasound.
  • the article is completely sealed before the two rotary envelopes are formed. This happens by forming ultrasonically sealed longitudinal seams and other seams.
  • the other seams are in particular perpendicular to the longitudinal seam.
  • an endless web of the packaging film is used in the production.
  • the articles are encased spaced from each other by the continuous web.
  • the continuous web extends or moves in a direction parallel to the longitudinal axis of the article and thus parallel to the longitudinal seam.
  • the longitudinal axis of the article is predetermined in particular by a candy through the oval configuration.
  • the invention further includes an apparatus for packaging a single, small article.
  • the advantageous embodiments and dependent claims described within the scope of the inventive arrangement or the method according to the invention accordingly find preferred application to the device according to the invention.
  • the device comprises an ultrasonic sonotrode and a corresponding counter-tool, in particular an anvil, for sealing the packaging film.
  • the device comprises a winding device for forming a double twist wrap on the packaging film.
  • the device according to the invention is designed for producing the arrangement according to the invention or for carrying out the method according to the invention.
  • FIG. 1 shows an arrangement 1.
  • the Figures 2 . 3 and 4 show details of a device 15 for the production of the arrangement 1.
  • the assembly 1 comprises a small article 12 (see FIG. FIG. 2 ) formed as a candy, and a packaging film 2.
  • the article 12 is packed in the packaging film 2.
  • the article 12 is oval and thus extends along a longitudinal axis. 3
  • a first twist wrap 4 and a second twist wrap 5 is formed on the packaging film 2.
  • the packaging film 2 was rotated about the longitudinal axis 3.
  • a first spin flag 6 is formed.
  • the second twist wrap 5 is formed.
  • a longitudinal seam 8 extends continuously between the two rotary envelopes 4, 5. At least two layers of the packaging film 2 are arranged one above the other at the longitudinal seam 8. The longitudinal seam 8 is sealed by means of ultrasound.
  • FIG. 1 two further seams 14.
  • the two other seams 14 are located at the outermost ends of the Drehfähnchen 6, 7. These other seams 14 are sealed by means of ultrasound.
  • the further seams 14 can also be formed directly on the rotary envelopes 4, 5. It can also Cold seal adhesive can be used. In another alternative accounts for the other seams 14th
  • the longitudinal seam 8 is formed over the entire length of the arrangement 1 along the longitudinal axis 3. That is, the longitudinal seam 8 extends from the upper end of the first Drehfähnchens 6 to the lower end of the second Drehfähnchens 7. Since the longitudinal seam 8 is sealed before forming the rotary envelopes 4, 5 with ultrasound, the longitudinal seam 8 is in the range of Drehfähnchen. 6 7 twisted and therefore in FIG. 1 poorly representable in these areas.
  • FIG. 2 shows an endless belt 11 of the packaging film 2.
  • the endless belt 11 extends or is moved in the direction of the longitudinal axis 3. Accordingly, the articles 12 are wrapped with its longitudinal axis 3 parallel to the extension direction of the endless belt 11 of the endless belt 11.
  • FIG. 2 shows on the endless belt 11 longitudinal seam portions 13 which are formed in the finished arrangement 1 to the longitudinal seam 8, and further seam portions 16 which form the further seams 14 in the finished arrangement 1.
  • the longitudinal seam regions 13 extend on both sides of the applied article 12 over several articles 12 away.
  • the packaging film 2 is folded over the articles 12, so that the two longitudinal seam regions 13 lie one above the other.
  • This state shows FIG. 3 ,
  • In FIG. 3 lie two layers of the packaging film 2 on top of each other.
  • These two layers of the packaging film 2 are located between an ultrasonic sonotrode 9 and a corresponding counter-tool 10. Ultrasonic vibration is applied to the ultrasonic sonotrode 9 so that the packaging film 2 is sealed and thus the longitudinal seam 8 is formed.
  • this longitudinal seam is approximately at right angles to the outside.
  • the longitudinal seam area 13 is marked or shaded. In fact, however, this area does not differ in its color or design from the remaining packaging film 2.
  • FIG. 2 shows the other seam portions 16 as perpendicular to the longitudinal axis 3 areas between the individual articles 12.
  • the other seams 14, at the outer ends of the final Drehfähnchen 6, 7 are prepared by an ultrasonic seal.
  • the further seam areas 16 are in FIG FIG. 2 marked or shaded drawn. In fact, however, these areas do not differ in color or design from the remaining packaging film 2.
  • the further seams 14 can also be produced with cold seal adhesive.
  • a cold seal adhesive is applied between the articles 12 on the endless belt 11.
  • FIG. 2 shows that the articles 12 are arranged with their longitudinal axis 3 parallel to the extension of the endless belt 11. This has the advantage that the longitudinal seam 8 can be formed continuously through the ultrasound sonotrode 9 when passing through the wrapped article. In all other turning machines, the individual packaging sheets, and not the hose, must be wrapped around the product, and then the longitudinal seam area can first be formed in cycles.
  • FIG. 4 shows a schematic view of the device 15 from the side.
  • the article 12 comes from the left in the device 15.
  • the endless belt 11 of the packaging film 2 is fed in and the articles 12 are enveloped by means of a forming shoe 17.
  • the longitudinal seam region 13 is closed and thus the longitudinal seam 8 is formed.
  • an endless tube 18 thus arises
