Definitions
- the invention relates to a shrink tunnel installation with improved flow behavior according to the preamble of patent claim 1 and to an associated method for shrinking a shrink film onto packing formations according to the preamble of patent claim 15.
- Shrink tunnels for shrink-wrapping a shrink wrap on pack formations for use in so-called "shrink packers", i.e., packers for packaging pack formations with shrink wrap, are well known.
- Packing formations are to be understood as the most varied packaged goods to be packaged with shrink film, in particular also pack formations consisting of several packaged goods or individual packagings, in particular also consisting of several containers, bottles, cans or similar individual packagings, which by means of the shrunk shrink film form a packaging unit or be summarized a container.
- the shrinking takes place here by a hot air or hot gas stream, hereinafter referred to as shrink gas flow, with which the respective, provided with the shrink film packing formation is applied to shrink the shrink film on the packing formation to form the packaging unit. More particularly, the shrink gas flow is directed to the sides of the packing formed by the shrink wrap to seal the overlapping ends of the shrink wrap there, i. for welding and / or gluing.
- the shrinkage gas stream is provided by a heating gas or shrinkage gas heater, which has at least one heating arrangement, which is operated in particular electrically or with a gaseous fuel, whereby, of course, liquid fuels are fundamentally conceivable.
- the heating gas heater has a burner which is designed for burning the gaseous fuel in an open-pore, ceramic or sintered metallic layer and gives off heat energy to the shrink gas flow, as is known, for example, from DE 10 2007 030 264 B4.
- the shrinkage gas flow uncontrollably encounters the packing formations enveloped by the shrinking film, so that the efficiency of the shrinking process depends on the peripheral shape of the pack formation to be packaged. Disadvantageously, this can also result in edge-side folding of the shrink film.
- the object is achieved on the basis of the features of the preamble of claim 1 and 15 respectively by its characterizing features.
- the essential aspect of the shrink tunnel installation according to the invention is that guide means for introducing the hot shrink gas flow into the tunnel interior are provided with a first flow direction oriented along the transport direction and / or a second flow direction oriented opposite to the transport direction.
- the targeted feeding of the shrinkage gas flow into the interior of the tunnel and thus to the shrinkage film wrapped packing formations prevents defective shrinkage points, resulting in a significant improvement in the quality of the shrinking process, particularly in film multipacks with printed film. This also results in a noticeable improvement in the efficiency of the shrinking process, especially in terms of energy.
- the guiding means are formed by air guiding means, which direct the hot shrinkage gas flow such that it enters the tunnel interior in the first and / or second flow direction.
- the hot air forming the shrinkage gas stream can therefore be generated particularly advantageously centrally and is then introduced into the tunnel interior via the air guidance means with a predetermined flow direction.

- the rear side of the shrink film lays down on the packing formation in the inlet zone and the front of the shrink film stands out from the pack formation.
- the front side of the shrink film attaches to the packing formation, and the back side of the shrink film lifts off the packing formation.
- the conductive means are designed such that the introduced into the tunnel interior hot shrinkage gas flow increases steadily in the transport direction.
- the guide means are designed to produce a uniformly distributed over the height of the tunnel interior Schrumpfgasstromes. Also by these measures, the quality of the shrinking process can be significantly improved.
- the tunnel interior is bounded by at least two lateral tunnel walls, wherein the guide means arranged along the lateral tunnel walls and / or at least partially formed by the lateral tunnel walls themselves and / or integrated into them.
- the lateral tunnel walls are in particular made of metal sheets which have a plurality of outlet openings for introducing the shrinkage gas flow into the tunnel interior, which form the guide means.
- the outlet openings are formed such that the emerging through the outlet openings Schrumpfgasstrom a first or second flow direction is impressed.
- the area of the lateral tunnel walls surrounding the outlet openings has an arched contour oriented in the direction of the tunnel interior, so that the outlet openings and the area of the lateral tunnel walls surrounding this form a nozzle-like structure.
- the outlet openings are introduced by punching or lasing in the lateral tunnel walls and the curved contour of the area surrounding the outlet openings then produced by embossing.
- the diameter of the outlet openings preferably increases along the interior of the tunnel.
