Problems solved by technology

If the bundle with the lower film cover pointing upwards is now transported via the constriction tunnel, this is advantageously supported by an upwardly directed hot air flow through the transport plane, but a downwardly directed hot air flow from the outflow surface stream and horizontally diverted hot air flow counteracts this desired effect

Embodiment Construction

[0036] figure 1 A schematic view of a shrinking device 1 according to the known prior art is shown. Items, in particular beverage containers, bottles 6 , cans or the like are put together in groups and wrapped with a shrink film 7 . These arrangements are also referred to as clusters 5 . The bundles 5 are transported on the conveyor belt 10 to the shrink tunnel 2 in the transport direction TR. Arranged in the shrink tunnel 2 are heating means (not shown), which, for example, impinge the bundle 5 with hot air, thereby shrinking the film 7 surrounding the bottle 6 . After the bundles 5 leave the shrink tunnel 2 , they are cooled with cooling air 22 by a fan 20 arranged above the conveyor belt 10 .

[0037] figure 2 A cross-section of the shrink tunnel 2 with two transport rails 11 for bundles (not shown) is shown. Via the so-called well walls 30 , 32 , hot air 40 is blown into the inner space 34 of the constriction channel 2 . The outer shaft wall 30 has nozzle openings 3...

Abstract

The present invention relates to a shrink tunnel, and particularly to a shrink channel (3) for shrinking packaging medium (7) that is combined around an object (6). The shrink tunnel comprises a transport plane (TE). The object (6) which is packaged by the packaging medium (7) is transported on the transport plane in a transport direction (TR). The shrink tunnel comprises at least two well walls (50,60) which are configured in parallel with the transport direction (TR) on the transport plane (TE) and / or above the transport plane. The well walls (50,60) respectively have two side surfaces (52,61) which are configured in parallel with the transport direction (TR), wherein, at least one side surface forms an outflow surface (52). Shrink medium (40) can be introduced into an inner space (34) of the shrink channel (3) by means of at least one outflow surface (52). The side surfaces (52,61), upper side surface and lower side surface (54,55) of the well walls (50,60) form edges (XO,XU) of the well walls (50,60), wherein the edges are perpendicular with the transport plane (TE) and the cross section of the transport direction (TR). According to the shrink channel, the width of the cross section gradually reduces in the direction of the transport plane (TE).

Description

technical field [0001] The invention relates to a shrink tunnel for shrinking a packaging medium around an assembly of goods according to the features of the preambles of claims 1 and 13 . Background technique [0002] Methods and devices for packaging articles are known from the prior art which use shrink films as the outer packaging of the articles. The shrink film is usually wound around the product assembly as a film blank by means of a rotary system. Such so-called clusters are transported via shrink tunnels. In the shrinking tunnel, the wrapped article is loaded with a shrinking medium, for example warm or hot air, whereby the shrink film is tightened so that the shrink film adheres tightly to the article and produces the finished shrink bundle. [0003] Bundle pieces are usually processed in a shrink tunnel on several parallel-guiding rails depending on their size. In order to be able to load all the bundles with warm air from all sides, means must also be provided...
