Abstract
This invention is directed to form openings in the heat shrink film for allowing cooling air to circulate between the articles while maintaining the structural integrity of the heat shrunk film. This is accomplished by slitting the heat shrink film and forming slots between the slitted parts of the film.
Description
- This invention relates to cooling or freezing an article or a bundle of articles after the article has been filmed wrapped and heat shrunk. The term article refers to a bundle of articles such as bottles or a single article.
- The prior art has placed articles in cartons, having holes in the carton, to allow cold air to circulate in the carton during the freezing or cooling of the articles. This technique of cutting holes in the heat shrink film for air circulation of the article has been tried without success. Cutting the holes mechanically with an heated die or a rotating blade while the heat shrink material is moving resulted in a hole size of about ⅜ inch. Larger holes were difficult to achieve. The cooling time with these small holes impeded the cooling time for these articles. The prior art was in need of a commercial viable way of creating openings large enough to allow sufficient air circulation to cool or freeze articles with a heat shrunk film.
- The prior art, shown in publication GB 2077692 shows forming slits or slots in the longitudinal direction for the insertion of labels. These machine described in this publication was sold.
- An objective of this invention is to form openings in the heat shrink film for allowing cooling air to circulate between the articles while maintaining the structural integrity of the heat shrunk film.
-
FIG. 1 shows wrapping film with slots around a bundle of articles prior to heat shrinking -
FIG. 2 shows separating the film into three ribbons separated by slots. -
FIG. 3 shows an article wrapped with a heat shrunk film having ribbons separated by slots. -
FIG. 1 shows a bundle of articles 1 being pushed into avertical plane 23 of a heat shrink film. Thevertical plane 23 is formed byfilm 9 coming from a bottom roll 2 andfilm 8 coming fromtop roll 3. The film leaving the top roll is separated by cutting the film using anarrangement 26 described inFIG. 2 . -
FIG. 2 shows slittingfilm 8 in a longitudinal direction usingcutting blades film guide roller 17. The center part of thefilm 19 passes overcenter film guide 18. The right separated side of the film pass between tiltedside rollers tilted rollers ribbons 24 is referred to as slots. A separation of about 22 mm or larger between the ribbons are needed to achieve proper ventilation of the cooling air through the slots. Although theFIG. 3 shows 3 ribbons the apparatus can be expanded to accommodate more ribbons depending on the size of the article. - After the
top film 8 has been separated into ribbons the article is transported on a conveyor and pushed through thevertical plane 23 of the film. The vertical plane is formed by the seal bar joining thefilm 9 from the bottom roller 2 and the separated parts of thefilm 8 from the top roller. Theseal bar 5 comes down from behind the article to seal the film thereby enclosing the article within the film. During the sealing process the seal bar cuts the film to release the wrapped article and seals the ends of the film from the rolls to form a new vertical plane for the next bundle of articles. - The sealed wrapped bundle is transported to a
heat shrink tunnel 6. After the film is heat shrunk, the wrapped article is transported to a freezer orcooler 7. The heat shrunk bundle can be bundled or palletized prior to entering the freezer or cooler. -
FIG. 3 shows a film wrapped bundle of articles wherein thetop film 8 is divided into threeribbons 24 separated byslots 27.Seal 25 joins thelower film 9 to theseparated ribbons 8. - Although the shown embodiment has the top film separated into ribbons, the embodiment can be changed so that the lower film is divided into separated ribbons.
Claims (13)
