Problems solved by technology

Currently, since adjustable machines capable of operating in single-lane or multi-lane modes of operation have only recently been developed, such as Neagle's U.S. Patent 5,765,336, it is possible to selectively heat single- or multi-lane packages wrapped in film. The issue of shrinkage remains unresolved

Embodiment Construction

[0034] in the attached picture figure 1 Single lane packaging of cylindrical items 10 to form a finished multi-pack 12 is illustrated. The basic steps in creating a multi-pack 12 include grouping the articles 10 in a sorting section 14, forming a tray 15 around the articles 10 in a tray forming section 16, and wrapping the articles 10 in a tube formed by heat shrinkable film 17 in a film wrapping section 18. , and hot air is applied at the constricted portion 20. The tube formed by the film 17 is a heat shrinkable sheet wrapped around the article 10, lap-sealed as will be described in detail herein, and has openings at laterally opposite ends. Application of hot air to the tube of film 17 causes the opening to contract to form a small, substantially oval opening, commonly referred to as a bull's eye 19 , at the transversely opposite end of the finished multi-pack 12 . although figure 1 While the use of a tray 15 surrounding the items 10 is shown, it is expressly contemplate...

Abstract

A shrink tunnel (100) for use with packaging machines utilizing heat shrinkable film (17). Air plenums (158, 160, 162, 164) positioned in the shrink tunnel (100) accurately direct heat at laterally opposed ends (188, 190, 198, 200, 202, 204, 206, 208, 212, 214, 218, 220) of film wrapped packages (192, 194, 196, 210, 216, 222) to shrink film into a bullseye (19). The air plenums (158, 160, 162, 164) are adjustable to accommodate different size packages or a differing number of lanes of operation. Interior air plenums (160, 162) are inserted between packages in lanes of a multiple lane packaging machine so that the laterally opposed ends of all packages have hot air directed at them.

Description

technical field [0001] The present invention relates to an adaptable shrink tunnel that applies hot air directly to specific portions of heat-shrinkable film in a packaging machine, wherein items packaged in heat-shrinkable film pass through packaging machines including single-lane, double-lane and three selectable operating modes are produced. Background technique [0002] The packaging of consumer and wholesale goods with heat shrinkable film is well known, the properties of the film causing it to wrap around the item prior to shrinking and then shrinking by the application of heat so that the film adheres tightly to the item to form the package. A special application of heat-shrinkable film in packaging is the secondary packaging of cylindrical items, such as bottles or cans for food, soup, beverages, etc. [0003] The secondary packaging of items such as bottles or cans usually includes a first step of arranging the items into a set that ultimately forms a multi-pack. ...
