Abstract

A foil strip composed of several layers is continually rolled up around an axis extending in its longitudinal direction to form a tubular body (38) in such a way that the two edges (42, 44) overlap. To effect welding, the overlapping edges are pressed together between two strips (16, 18) which are driven in a circulating manner in the longitudinal direction. The inner strip (16) which passes inside the tubular body (38) is provided with a longitudinal groove (40) which at least partly receives the region of the overlapping edges (42, 44). The longitudinal groove (40) forms the region of the seam of the tubular body (38) which is facing inward, and prevents the plastic material which is liquefied for welding from expanding as a result of the application pressure. In this way it is ensured that the material of the two edges (42, 44) is fully welded together, so that no pressed-out edge regions of liquid material cool prematurely and therefore do not adhere to the opposed material layer.

Description

Opfindelsen angår en fremgangsmåde af den art, der er angivet i indledningen til patentkrav 1, samt et apparat af den art, der er angivet i indledningen til patentkrav 8.The invention relates to a method of the kind set forth in the preamble of claim 1, and to an apparatus of the kind set forth in the preamble of claim 8.

Et sådant apparat er kendt fra US patentskrift nr.Such an apparatus is known from U.S. Pat.

5 3.388.017. Ved rørlegemer, der er fremstillet ved hjælp af dette apparat, har det imidlertid vist sig, at svejsesømmenes ydre rande udviser steder, hvor svejsningen mangler, og som tenderer til at falde af, eller endda til at gå itu. Materialerester, der er faldet af inde i rørlegemet, kan da 10 komme ind i det materiale, som skal emballeres, og forurene det på utilladelig måde.5,388,017. However, with tubular bodies manufactured by this apparatus, it has been found that the outer edges of the weld seams exhibit places where the weld is missing and which tend to fall off, or even break. Material residues that have fallen off inside the tubular body can then enter the material to be packaged and impermissibly contaminate it.

Opfindelsen beror på den erkendelse, at de områder, der tenderer til at falde af, dannes af det materiale, som under svejsningen presses ud af svejsesømmen. De ydre rande 15 af dette udpressede materiale afkøler hurtigt på grund af deres meget ringe tykkelse, hvorfor de ikke mere kan indgå nogen svejseforbindelse med det tilgrænsende materiale.The invention is based on the recognition that the areas which tend to fall off are formed by the material which is pressed out of the weld seam during welding. The outer edges 15 of this extruded material cool rapidly because of their very small thickness, and therefore they can no longer make any welding connection with the adjacent material.

Formålet med opfindelsen er derfor at angive en fremgangsmåde og et apparat af den indledningsvis angivne art, 20 ved hvilke svejsesømmen ikke har uforsvejste rande af udpresset materiale.The object of the invention is therefore to provide a method and an apparatus of the kind mentioned in the preamble, wherein the welding seam does not have unshelded edges of extruded material.

Dette formål opnås ifølge opfindelsen ved de i patentkravene 1 og 8's kendetegnende dele angivne ejendommeligheder .This object is achieved according to the invention by the characteristics specified in claims 1 and 8.

25 Længdenoten ved det indre bånd, som ligger an mod den søm, der skal svejsebehandles, meddeler svejsesømmen en defineret form og forhindrer dannelsen af udtrædende materialerande. Ved den kompakte bevaring af svejsesømmen sikres en ensartet opvarmning af foliebåndets hinanden overlappende 30 rande, hvorfor dannelsen af materialesteder, der afkøles i utide, udelukkes. Ved anbringelsen af længdenoten i det indre bånd flyttes svejsesømmen indefter, så at ydersiden af det dannede rørlegeme har en i det væsentiikge jævn overflade.25 The longitudinal note of the inner band which abuts the seam to be welded gives the weld seam a defined shape and prevents the formation of protruding material edges. In the compact preservation of the weld seam, a uniform heating of the overlapping edges of the foil strip ensures that the formation of material places which are cooled out in the past is excluded. By placing the longitudinal note in the inner band, the weld seam is moved inwardly so that the outer surface of the formed tubular body has a substantially smooth surface.

35 Opfindelsen medfører endvidere den fordel, at der ved et flerlags-foliebånd, af hvilket kun det indre lag må DK 168733 B1 2 komme i bnerøring med den færdige emballagetubes indhold, sikres en gennemgående forbindelse af det indre lag ved svejsesømmen, hvis kanten af foliebåndets indre rand i tværsnit tilskæres skråt på en sådan måde, at det indre lag 5 overrager foliebåndets øvrige lag. Ved hjælp af længdenoten i det indre bånd trykkes det udragende randområde under overdækning af de øvrige lag, ned til det mindre lag af det over for beliggende randområde.The invention furthermore has the advantage that in a multi-layer foil tape, of which only the inner layer may come into contact with the contents of the finished packaging tube, a continuous connection of the inner layer at the welding seam is ensured if the edge of the foil strip the inner edge in cross section is cut obliquely in such a way that the inner layer 5 overcomes the other layers of the foil tape. By means of the longitudinal groove in the inner band, the protruding edge area is pressed under cover of the other layers, down to the smaller layer of the opposite edge area.

Ved hjælp af opfindelsen opnås en fejlfri svejsesøm 10 til en emballagetube af høj kvalitet.By means of the invention, a flawless weld seam 10 is obtained for a high quality packaging tube.

Foretrukne udførelsesformer som angivet i kravene 2 til 4, samt 9 og 10 er fordelagtige, hvis f ler lags-f oliebåndet har et metallisk materialelag, fortrinsvis et aluminiumlag, ved hvis induktive opvarmning de tilgrænsende form-15 stoflag bringes på svejsetemperatur.Preferred embodiments as claimed in claims 2 to 4, as well as 9 and 10 are advantageous if the multi-layered oil strip has a metallic material layer, preferably an aluminum layer, in whose inductive heating the adjacent molding layers are brought to welding temperature.

Foretrukne udførelsesformer ifølge krav 5 til 7, samt 11 og 12 er fordelagtige ved forarbejdningen af et foliebånd, der ikke indeholder noget metallag, eller ved hvilket metallaget er for tyndt til, at der kan frembringes 20 tilstrækkelig svejsevarme ved hjælp af højfrekvensenergi. I dette tilfælde sker overføringen af svejsevarmen fra de som svejseværktøjer tjenende, roterende bånd, ved kontakt med foliebåndet.Preferred embodiments according to claims 5 to 7, as well as 11 and 12, are advantageous in the processing of a foil tape containing no metal layer or in which the metal layer is too thin for sufficient welding heat to be produced by high frequency energy. In this case, the heat of the welding is transferred from the rotating band serving as welding tools upon contact with the foil band.

De som svejseværktøjer tjenende bånd består fortrins-25 vis af stål. Deres opvarmning ved hjælp af højfrekvensenergi har den særlige fordel, at ingen andre dele medopvarmes. Da disse bånd fortrinsvis har en lille masse, kan de ikke alene hurtigt opvarmes til den nødvendige temperatur, men de kan også nedkøles hurtigt, således at der ved en stor arbejds-30 hastighed kan frembringes en særlig god økonomi.The strips serving as welding tools preferably consist of steel. Their heating with the help of high frequency energy has the special advantage that no other parts are co-heated. Since these bands preferably have a small mass, not only can they be rapidly heated to the required temperature, but they can also be cooled rapidly so that at a great operating speed a particularly good economy can be produced.

En yderligere forøgelse af arbejdshastigheden kan opnås ved den i krav 12 angivne foretrukne udførelsesform.A further increase in the operating speed can be achieved by the preferred embodiment of claim 12.

Opfindelsen skal i det følgende forklares nærmere under henvisning til tegningen, på hvilken 35 fig. 1 viser skematisk et apparat til fremstilling af rørlegemer til emballagetuber, set fra siden, DK 168733 B1 3 fig. 2 i større målestok apparatets rørdannelsesområde, fig. 3 samme område i tværsnit, og fig. 4 i større målestok en enkelthed i fig. 3.The invention will now be explained in more detail with reference to the drawing, in which FIG. 1 is a schematic side view of an apparatus for the manufacture of tubing for packaging tubes, side view, FIG. 2 on a larger scale the pipe forming area of the apparatus; FIG. 3 shows the same cross-sectional area, and FIG. 4 on a larger scale a simplicity of FIG. Third

5 Det i fig. 1 skematisk viste apparat får tilført et foliebånd 10 fra en ikke vist forrådsrulle. Båndet, som består af flere lag, har et aluminiumlag, som er inkorporeret i mindst to termoplastiske formstoflag. Det mod tubens indre vendende formstoflag vender under tilførselen opefter. I 10 apparatet oprulles foliebåndet omkring en i båndets længderetning forløbende længdeakse kontinuerligt til et rør med hinanden overlappende rande, som sammensvejses ved påvirkning ved varme. Til foliebåndets oprulning tjener et neden under foliebanen anbragt, omløbende, drevet rem 12. Ved hjælp af 15 føringselementer 14 hvælves remmen 12 med sine to rande tiltagende opefter, for at oprulle foliebåndet omkring en i længderetningen oven over remmen 12 forløbende dorn.5 The embodiment of FIG. 1 schematically, a foil tape 10 is supplied from a supply roll not shown. The multi-layered strip has an aluminum layer which is incorporated into at least two thermoplastic plastic layers. The plastic layer facing the inner layer of the tube faces upwards during the supply. In the apparatus, the foil strip is wound about a longitudinal axis extending longitudinally of the strip continuously into a tube with overlapping edges, which are welded together by heat action. For the roll-up of the foil strip, a circular, driven belt 12 is placed below the foil web, by means of 15 guide elements 14, the strap 12 is arched with its two edges increasing upwardly, to roll the foil strip about a longitudinal strip above the belt 12.

De heraf resulterende, ved to indbyrdes parallelle kanter begrænsede rande af foliebåndet 10 bliver presset 20 mod hinanden imellem et indre bånd 16 og et ydre bånd 18.The resulting edges, bounded by two mutually parallel edges, of the foil band 10 are pressed 20 against each other between an inner band 16 and an outer band 18.

De to bånd 16 og 18 tjener som presseværktøjer. Det indre bånd strækker sig langs med dornen inden i det rør, der skal fremstilles til en omstyringsrulle, således at det tilbageføres inden i det dannede tuberør.The two bands 16 and 18 serve as pressing tools. The inner band extends along the mandrel within the tube to be made into a guide roll so that it is returned within the tubular tube formed.

25 Før det indre bånd 16, hvis en omstyringsrulle 22 når frem til rørdannelsesområdet 24, kan det i sin føringsbane ved hjælp af en indretning 26 forvarmes induktivt. En for-varmning er imidlertid ikke tvingende nødvendig, fordi der til frembringelse af svejsevarmen tjener en i rørdannelses-30 området 24 placeret svejseindretning 28, som induktivt ved hjælp af højfrekvensenergi opvarmer de i foliebåndet inkorporerede aluminiumfolier. Opvarmningen er da ved en dosering af højfrekvensenergien således afmålt, at de termoplastiske formstoflag af foliebåndet opvarmes til en passende svejse-35 temperatur. Under svejsningen samt derefter sammenpresses de hinanden overlappende rande af det dannede tuberør ved DK 168733 B1 4 hjælp af de omløbende, drevne bånd 16 og 18. Efter svejsningen afkøles den dannede svejsesøm ved hjælp af et omløbende, drevet, endeløst kølebånd 30, medens der opretholdes et tilpresningstryk mod det indre bånd 16. Den aktivt frem-5 kaldte afkøling tillader en forøgelse af arbejdshastigheden.25 Before the inner band 16, if a guide roller 22 reaches the tube forming region 24, it can inductively preheat in its guide path by means 26 a device 26. However, a preheating is not imperative because in order to generate the welding heat, a welding device 28 located in the tube forming region 24 which inductively by high frequency energy heats the aluminum foils incorporated in the foil strip. The heating is then metered at a dose of the high frequency energy such that the thermoplastic plastic layers of the foil band are heated to a suitable welding temperature. During welding, and then the overlapping edges of the formed tubing are compressed by means of the circumferentially driven strips 16 and 18. After the welding, the formed weld seam is cooled by means of a circumferentially driven, endless cooling strip 30 while maintaining a compression pressure against the inner band 16. The actively induced cooling allows an increase in the operating speed.

I en retning 32 forlader de langs langsiden sammensvejste, og ved den viste skæremekanisme afdelte rørlegemer apparatet, for derefter at blive kompletteret ved anbringelse af et tubehoved og en lukkehætte.In a direction 32, the longitudinal welds leave the welded together along the longitudinal section of the cutter shown, and the apparatus is then separated, to be supplemented by the fitting of a tube head and a closure cap.

10 Af fig. 2 fremgår, hvorledes det indre bånd i rørdan nelsesområdet 24 føres langs med dornen 34 hen til omstyringsrullen 20, og derpå tilbage. Båndets øverste part 16' ligger an mod dornen 34, medens dets nedre part 16" tilbageføres i en i dornen 34 anbragt længdenot 36. Det frem-15 stillede tuberør 38 er vist med stiplede linier.10 From FIG. 2 shows how the inner band of the tube forming region 24 is guided along the mandrel 34 to the guide roll 20, and then back. The upper portion 16 'of the belt abuts against the mandrel 34, while its lower portion 16 "is returned to a longitudinal pin 36 located in the mandrel 34. The tubing 38 provided 38 is shown in dotted lines.

Fig. 3 viser et tværsnit igennem rørdannelsesområdet 24 i et afsnit, hvor foliebåndet ved hjælp af remmen 12 allerede er oprullet til et tuberør. Figuren viser tydeligt, hvorledes den øverste part 16' af det indre bånd 16 er ført 20 på dornen 34, medens båndets nedre part 16" tilbageføres i en not 36. Det ydre bånd 18 presses ved hjælp af den fjedrende anbragte svejseindretning 28 mod de hinanden overlappende rande af det dannede rør 38.FIG. 3 shows a cross-section through the tube forming region 24 in a section where the foil tape is already wound up by means of the belt 12 for a tubular tube. The figure clearly shows how the upper part 16 'of the inner band 16 is guided 20 on the mandrel 34, while the lower part 16' of the belt is inserted into a groove 36. The outer band 18 is pressed by means of the resiliently arranged welding device 28 against each other. overlapping edges of the formed tube 38.

Fig. 4 viser en enkelthed af rørdannelsesområdet 24.FIG. 4 shows a simplicity of the tube forming region 24.

25 Det fremgår af figuren, at det indre bånd 16 har en længdenot 40, som tjener til formgivning af den indefter vendende side af tuberøret 38's rørsøm. Længdenoten 40 meddeler rør- . sømmen en defineret form og forhindrer, at de hinanden overlappende rande 42 og 44 under sammenpresningen udvides ukon-30 trolleret, idet den begrænser en udløben af det under svejsningen påsmeltede materiale. Materialet er et termoplastisk formstof, især polyethylen, polypropylen eller disses polymerer. Dette svejselige formstof danner de ydre lag af det til et rør 38 formede foliebånd. Foruden et mellem formstof-35 lagene inkorporeret aluminiumlag kan foliebåndet have yder- DK 168733 B1 5 ligere lag, eksempelvis et papirlag, samt vedhængslag for aluminiumfolien.25 It can be seen from the figure that the inner band 16 has a longitudinal groove 40 which serves to form the inner side of the tube seam 38 of the tube. The longitudinal note 40 notifies the pipe. The seam is a defined shape and prevents the overlapping edges 42 and 44 from expanding uncontrolled during compression, limiting an outlet of the material melted during welding. The material is a thermoplastic resin, especially polyethylene, polypropylene or their polymers. This weldable resin forms the outer layers of the foil tape formed into a tube 38. In addition to an aluminum layer incorporated between the plastic layers, the foil tape may have additional layers, such as a paper layer, as well as pendant layers for the aluminum foil.

Ved en udførelsesform af apparatet til fremstilling af rørlegemer af et foliebånd, og uden inkorporeret metallag, 5 eller kun med et meget tyndt metallag, opvarmes de to som svejseværktøjer tjenende, omløbende, drevne bånd 16 og 81 til den nødvendige svejsetemperatur induktivt ved hjælp af højfrekvensenergi. Opvarmningen kan ske foran rørfremstillingsområdet 24, se fig. 2, eller for det ydre bånd 18's 10 vedkommende også ske inden for dette område ved hjælp af passende opvarmningsindretninger. I et sådant tilfælde tjener indretningen 26 ikke til forvarmning af det indre bånd 16, men til en fuldstændig opvarmning af dette bånd til den fornødne svejsetemperatur. Det ydre bånd kan ved denne ud-15 førelsesform opvarmes enten før rørdannelsesområdet 24, se fig. 2, eller inden for dette område, under anvendelse af indretningen 28.In one embodiment of the apparatus for producing tubular bodies of a foil tape, and without incorporated metal layer, 5 or only with a very thin metal layer, the two welding tools which serve as welding circuits 16 and 81 are heated inductively by means of high frequency energy. . The heating can take place in front of the pipe-making region 24, see fig. 2, or in the case of outer band 18, also within this range by means of suitable heating devices. In such a case, the device 26 does not serve to preheat the inner band 16, but to completely heat that band to the required welding temperature. In this embodiment, the outer band can be heated either before the tube forming region 24, see FIG. 2, or within this range, using the device 28.

De omløbende, drevne bånd 16 og 81 består fortrinsvis af stål, såfremt opvarmningen sker induktivt ved hjælp af 20 højfrekvensenergi. Tilvejebringes svejsevarmen imidlertid udelukkende ved hjælp af indretningen 28 umiddelbart i foliebåndets aluminiumlag, kan de som presseværktøjer tjenende bånd 16 og 18 eksempelvis også bestå af polytetrafluorethy-len. Indretningen 26 er i dette tilfælde ikke påkrævet.The orbital driven bands 16 and 81 preferably consist of steel, if the heating is done inductively by 20 high frequency energy. However, if the welding heat is provided solely by means of the device 28 immediately in the aluminum layer of the foil strip, the strips 16 and 18 serving as pressing tools may also consist, for example, of polytetrafluoroethyl. In this case, the device 26 is not required.

25 De til induktiv forvarmning tjenende indretninger 26 og 28 udviser i det væsentlige en højfrekvensspole, hvis afgivne energi er koncentreret på det område, som skal opvarmes. Til aktivering af sådanne højfrekvensspoler tjener kendte højfrekvensgeneratorer.The inductive preheating devices 26 and 28 exhibit essentially a high frequency coil whose delivered energy is concentrated in the area to be heated. For activating such high frequency coils, known high frequency generators serve.

30 Flerlagsfolier af den angivne art, der har et metal lag, fortrinsvis et aluminiumlag, er kendt. Apparatet er imidlertid også egnet til forarbejdning af et foliebånd, som kun består af et enkelt termoplastisk formstoflag.30 Multilayer foils of the specified type having a metal layer, preferably an aluminum layer, are known. However, the apparatus is also suitable for processing a foil tape consisting of only a single thermoplastic plastic layer.
