Definitions

  • the invention relates to a tubular film packaging machine, comprising two conveying devices with two associated each portal-like forming shoulders, which are each intended to redirect a respective supplied film web in the conveying direction of the respective conveyor, that in the conveying direction behind the forming shoulders a respective tunnel-like film tube is formed as a package in which the two conveying devices are intended to move groups of consumable products, in particular tissue products, to be packed thereon at a predetermined feed rate through the respective forming shoulder into the respective tunnel-like film tube, the latter moving at the same feed rate as the consumable products and the two conveyors are arranged along a common plane parallel to each other.
  • tissue products in particular rolls such as kitchen rolls or toilet paper rolls, which are packed as roll groups in foil bags, for example in packaging sizes of 1 x 3, 1 x 4, 2 x 3, 2 x 4, 2 x 5, 3 x 3, 3 x 4 or 3 x 5 rolls.
  • a typical roll diameter is for example about 10 - 15cm, with a typical length of about 10cm or 25cm.
  • Tissue products also include other hygiene articles and, for example, folded and / or stacked products such as handkerchiefs or napkins, which are to be packaged in groups in an analogous manner before they reach the retail outlet.
  • Tissue products are consumer products with relatively low manufacturing costs compared to consumer goods, so that the effort that has to be done for their packaging is to be minimized.
  • a carrying handle is provided as part of the foil bag, by means of which the foil bag with the rolls wrapped therein can be carried particularly easily. It should be noted that such a carrying handle with a corresponding carrying hole for the secure handling of the foil bag must be designed to be stable in order to avoid tearing. A double thickness of the film material is often not sufficient.
  • tissue products are under a consumer product but also a variety of other consumer goods to understand, for example, in small boxes prepackaged foods or filled drinking containers such as Tetrapaks.
  • the corresponding groups of consumable or tissue products are pushed during the packaging process into a respective prefabricated foil bag, which is subsequently welded.
  • a supernatant of sixteenzusch spaenden film areas is required, the supernatant is then cut off after welding and discarded as waste.
  • a tubular film packaging machine of the type mentioned in the introduction is characterized in that the respective lateral edge regions of the two film webs from which the two tunnel-like film tubes are formed lie in a folded plane region lying between them in that in the fold plane region located between the tunnel-like film tubes, the lateral edge regions of the film webs shaped into tunnel-like film tubes are overlappingly arranged in a plurality of film layers, and in that the fold plane region comprises at least two film layers which are formed from edge regions of the two film webs.
  • the basic idea of the invention is to use the film supernatant as the starting point for a carrying handle.
  • the principal minimum of layers is two, wherein in each case two edge regions of the respective film webs open in the same film layers, preferably this abutting, and wherein the abutting edges of the two layers are then offset transversely to the conveying direction against each other, for example by a few centimeters, so as to ensure a high stability after the welding.
  • a number of two layers will in most cases not provide sufficient stability for a carrying handle unless the thickness of the film webs as a whole is correspondingly high. However, this would ultimately mean an excessive use of material in the film bag, which would then be more stable than usually needed.
  • the two forming shoulders are configured such that the respective lateral edge regions of the two film webs from which the two tunnel-like film tubes are formed lie in a folded plane region lying between them, and this includes exactly two layers of film.
  • a further variant of the arrangement of the edge regions of the film webs is that each edge region of the two film webs forms a complete position in the folded plane region, with which a total of four film layers are present. Depending on the film thickness, however, this could already mean a stability for a carrying handle, which is higher than needed. By additional folding of the edge regions in the folded plane region, theoretically more than four film layers can be realized.
  • the core element of the film tubular packaging machine according to the invention are the two forming shoulders, which are preferably laterally continuously fed to a respective film web, which is deflected in the conveying direction, that from a tunnel-like film tube is formed, wherein the respective two edge regions the two film webs open into a lying between the film tubes common Falzebenen Scheme.
  • the vertical height of the folded plane region is preferably at half the height of the packaging, so that the carrying handle is in the middle and the packaging with the consumption or tissue products contained therein can then be carried on the carrying handle without imbalance.
  • a forming shoulder is in the broadest sense comparable with a portal whose inner cross section corresponds approximately to the cross section of the film bag to be produced.
  • the film is deflected from the outside around the forming shoulder in such a way that the respective film tube is formed on its inner cross section, which is ideally moved continuously in the conveying direction of the conveying device.
  • a continuous movement of the respective film tubes can be achieved by pushing the groups or formations of consumable or tissue products to be packaged through the portal-like opening of the forming shoulder, for example by means of a slider or driver, the conveyor being located behind the forming shoulder above and below the film tube synchronously running conveyor belts, between which then pushed through the respective form shoulder and now located in the respective film tube consumable or tissue products are clamped so that they are promoted together and synchronously with the film tube.
  • a conveyor device can consist of a plurality of sub-conveying devices connected in series, for example conveyor belts, wherein typically additional carriers can also be provided, for example to form groups of consumable or tissue products.
  • Such drivers can usually drive only to the front edge of the forming shoulders.
  • a retractable plate with a slide is optionally provided in front of the forming shoulders.
  • the retractable plate with a behind the pusher ensures, before the next group or formation is inserted, that between the two formations of the necessary distance arises in order to perform the transverse welding can. This ensures that, for example, the last roll-shaped consumable or tissue product of a group or formation that is located in the forming shoulder does not fall out backwards or is wrapped too loosely by the film tube.
  • the two forming shoulders are configured such that the folded plane region has exactly three film layers, wherein a respective film layer is formed from two non-overlapping lateral edge regions of two film webs which abut one another at their edges.
  • the two conveying devices have a plurality of in the region of the respective portal-like form shoulder successively connected part conveyors, wherein in the conveying direction behind the respective form shoulder two respectively synchronously running band-like part conveyors are provided below and above the respective tunnel-like film tube.

This is designed such that located on the conveyor consumable or tissue products are pushed with the drive slide through the forming shoulder and there passed the respective synchronously running band-like part conveyors for further transport.
  • a conveyor device may have one or even a plurality of tracks for rows of, for example, roll-shaped or else stacked consumable or tissue products.
  • a drive slide can be provided for pushing groups or formations of consumable or tissue products to be packaged with a distance between the groups in the direction of subsequent transverse welding means.
  • this distance may be, for example, about a roll diameter.
  • Such a generated distance is a prerequisite for a subsequent transverse welding of the respective foil bag.
  • this has in the conveying direction behind the forming shoulders for the mechanical support of the folding plane area a synchronous to the band-like Operanovurgichalschen movable tape-like support device to about half vertical height of the respective group of consumable or Tissue area to be packaged, for example, one or more moving bands which are preferably made of Teflon or at least coated in the region of a longitudinal welding device.
  • a moving band which are preferably made of Teflon or at least coated in the region of a longitudinal welding device.
  • the film tube packaging machine has means for needling together the film layers in the folded plane region. This is done for example by means of a needle roller with counter-roller.
  • the folded plane region can be connected in a dimensionally stable manner even before it is welded, thus simplifying further processing in an advantageous manner.
  • this means comprises a longitudinal welding device in order to weld the film layers together in the folded plane region, as well as a longitudinal cutting device for cutting the welded folded plane region.
  • a welding is done for example by means of one or more hot air nozzles, but there are quite a variety of other alternatives conceivable.
  • the separation or sealing of the film ends located in the folded plane area is effected for example by means of a so-called "slit sealer".
  • this means has to carry out a transverse welding of the parallel tunnel-like film tubes running along a common plane and thus to close them, which also has a transverse cutting device.
  • the means for transverse welding and the cross-cutting device are adjustable in a further embodiment variant along the conveying direction, so that the distance between the front edge of the forming shoulders and transverse welding, through which the length of the package is determined, is adaptable.

  • transverse welding preferably two parallel welds are produced simultaneously, one for the two backward packs and the other for the bag formation still in between the press belts.
  • a cross cutter separates the two bag formations between the transverse welds, for example a serrated knife which is pneumatically driven.
  • a respective carrying hole is punched by means of a punching device, so that a carrying handle is formed from the respective projection.
  • a punching device for this purpose, it is expedient that the respective packaging bags are previously taken over by a drive unit with pressure belts in order to ensure a secure positioning during punching.
