Den foreliggende opfindelse angår en maskine til vikling af baneformet folielignende materiale til ruller, især plastfolie fra en ekstruder, og af den art, hvor viklingen sker om en spolestang, eventuelt forsynet med et rør truk-5 ket ind over spolestangen, der er lejret frit roterbar ved sine ender og bringes i rotation ved kontakt med en drevet spolevalse, og hvor spolestangens lejring er indrettet således, at den bevæges bort fra spolevalsen i takt med rullens voksende diameter, og at der er en svingbar lejret 10 skæremekanisme med et knivblad i hele materialebanens bredde og et antal ved kniven beliggende luftdyser og en drivmekanisme, der kan svinge skæremekanismen fra en stilling i afstand fra materialebanen, i maskinens brugsstilling fortrinsvis under spolevalsen, til en stilling 15 i materialets bane til overskæring af materialebanen i materialets fremføringsretning efter spolevalsen, når rullen har nået den forud fastsatte diameter, og at der er et styreorgan, der samtidig med overskæring af banen frigør en ny spolestang fra et magasin for tomme 20 spolestænger oven over spolevalsen og med et organ til udtagning af en spolestang fra magasinet og ilægning i maskinen, hvorhos styreorganet samtidig åbner for luftdyserne, der er rettet således, at materialebanens ende slynges om den ny spolestang.The present invention relates to a machine for winding web-like foil-like material for rollers, in particular plastic foil from an extruder, and of the kind in which the winding takes place about a coil rod, optionally provided with a tube drawn over the coil rod which is stored freely. rotatable at its ends and rotated by contact with a driven spool roller, wherein the spool rod bearing is arranged so that it is moved away from the spool roll as the diameter of the roll increases, and that there is a pivotally mounted cutter mechanism with a knife blade throughout the width of the material web and a number of air nozzles located at the knife and a drive mechanism capable of pivoting the cutting mechanism from a position at a distance from the material web, preferably in the machine's operating position, preferably under the bobbin roller, to a position 15 in the web of material for cutting the web of material in the direction of feed of the material when the roller has reached the predetermined diameter and that there is a guide member which simultaneously cutting the web releases a new bobbin rod from a magazine for empty 20 bobbin rods above the bobbin and with a means for removing a bobbin from the magazine and loading into the machine, the control means simultaneously opening to the air nozzles which are directed so that the end of the material web is flung about the new bobbin.

25 Ved overskæring af foliebanen frigøres en ny spolestang og samtidig åbnes for luftdyserne, der er rettet således, at materialebanens ende slynges om den ny spolestang. Ved overskæringen udnyttes det velkendte fænomen med, at enderne ved overskæring af et udspændt tov 30 svirper til siderne, idet materialebanen i overskæringsøjeblikket er udspændt mellem spolevalsen og rullen, og overskæringen af materialebanen sker momentant i hele banens bredde. Selv om materialet er forholdsvis tyndt, 2 14668Λ vil det alligevel kunne mærkes, at der er en større spænding på ydersiden af folien, når den krummes over spolevalsen, hvilken forskel i spænding bevirker, at materialet af sig selv slynges omkring spolestangen, der udløses 5 fra magasinet, frem for til den anden side ned mod spolevalsen. Når kniven anbringes således, at den kommer nedefra og overskærer folien, vil den desuden trykke folien et stykke opefter, før den brister, og således hjælpe til med at slynge folien omkring spolestangen. Desuden hjæl-10 per antallet af luftdyser, der kan være egentlige dyser eller en luftspalte, som sender en luftstråle mod folieenden og rettet opefter, til med at slynge folieenden om stangen. På trods heraf er det ikke altid sikkert, at foliebaneenden slynges om spolestangen.25 When cutting the foil web, a new bobbin bar is released and at the same time opens to the air nozzles which are directed so that the end of the material web is wound around the new bobbin bar. In the cutting, the well-known phenomenon is utilized in that the ends, by cutting a stretched rope, 30 flips to the sides, with the material web at the moment of cutting being stretched between the spool roller and the roller, and the cutting of the material web occurs instantaneously throughout the width of the web. Although the material is relatively thin, it will nevertheless be felt that there is a greater tension on the outside of the foil as it curves over the coil roll, which difference in tension causes the material itself to be wound around the coil rod which is released. from the magazine, rather than to the other side down towards the bobbin. Furthermore, when the knife is positioned so that it comes from below and cuts the foil, it will push the foil up a bit before it breaks, thus helping to wrap the foil around the bobbin. In addition, the number of air nozzles, which may be actual nozzles or an air gap which sends an air jet towards the foil end and directed upwards, helps to wrap the foil end about the rod. Despite this, the foil web end may not always be wound around the bobbin.

15 For yderligere at sikre, at folieenden virkelig griber om spolestangen, kan maskinen indrettes som angivet i den kendetegnende del af kravet ved, at der umiddelbart over spolevalsen er et antal lodrette remme lagt omkring en omløbs- og drivvalse og fordelt over materiale-20 banens bredde, og at et drivaggregat til drivning af remmenes omløb er indrettet til at kunne aktiveres under skiftet af spolestangen, og at remmenes omløbsretning er den samme som spolevalsens. Foruden at remmene sætter den ny spolestang i rotation under skiftet og 25 alene af den grund hjælper med til at sikre, at foliebaneenden vikles om spolestangen, fanger remmene samtidig enden og trækker den ind mellem disse og spolestangen, der nu er i rotation, og foliebaneenden vil da med sikkerhed vikles om denne.To further ensure that the foil end really grips the bobbin rod, the machine can be arranged as set forth in the characterizing portion of the claim by having immediately a plurality of vertical straps placed around a bypass and drive roller and distributed over the material web of the bobbin. width, and that a drive assembly for driving the orbit of the belts is adapted to be actuated during the shift of the bobbin and that the direction of rotation of the belts is the same as that of the bobbin. In addition to the straps putting the new bobbin rod in rotation during the shift and for that reason alone, it helps to ensure that the foil web end wraps around the bobbin, at the same time the straps catch the end and pull it in between it and the bobbin now in rotation and the foil web end will surely be wrapped around this one.

I det følgende skal der med henvisning til den ledsagen-30 de tegning beskrives en udførelse af maskinen beregnet til vikling af plastfolie.In the following, with reference to the accompanying drawing, an embodiment of the machine intended for winding plastic foil will be described.

146684 3 På tegningen viser: fig. 1 et endebi 1 lede af maskinen ifølge opfindelsen, hvor bagved liggende dele er vist i pukteret streg, 5 fig. 2 et billede af maskinen ifølge opfindelsen set forfra, af overskuelighedshensyn med udeladelse af folien, omløbs-, køle- og dansevalse samt magasinet til de nye spolestænger, fig. 3 et detaljeret udsnit omkring spolevalsen 10 set fra siden, med skiftemekanismen til spolestænger, og visende overskæringskniven og luftdyserne, fig. 4 et forstørret snit gennem overskæringskniven og luftdyserne, samt 15 fig. 5 et detaljeret udsnit omkring spolevalsens ene ende set forfra.In the drawing: FIG. 1 is an end view of the machine according to the invention, with the underlying parts shown in the dotted line; FIG. 2 is a front view of the machine according to the invention, for reasons of clarity, omitting the foil, orbital, cooling and dance rolls and the magazine for the new bobbin rods; FIG. 3 is a side elevational view of the spool roller 10, with the spool rod changing mechanism, showing the cutting knife and air nozzles; FIG. 4 is an enlarged section through the cutting knife and air nozzles; and FIG. 5 is a front view of a detailed section around one end of the bobbin.

Maskinen er bygget op på et dertil udformet stel 1, der i det væsentlige består af to L'formede endestykker, hvori maskinens valser er lejret.The machine is made up of a frame 1 formed therefor, consisting essentially of two L-shaped end pieces in which the rollers of the machine are mounted.

20 Nu med særlig henvisning til fig. 1 føres plastfoliebanen 2, der kommer fra et på tegningen ikke vist anlæg til fremstilling af folien, ind foroven i maskinen, hvor den løber omkring en omløbsvalse 3 til en kølevalse 4, der afkøler den endnu varme folie, så den kan 25 opvikles i ruller. Fra kølevalsen 4 går folien omkring en dansevalse 5, der regulerer banens hastighed, så der kommer ens spænding i den, og derfra går folieba- 146684 4 nen 2 ned til en stræk- og glattevalse 6, der, som navnet siger, strækker og glatter folien. Herfra går foliebanen 2 op til en spolevalse 7, hvor banen bliver trykket imod af en tilholdervalse 8, der er indrettet 5 således, at man med en luftcylinder 9 kan svinge tilholdervalsen 8 væk for at lette isætningen af en ny bane 2. De forskellige valser trækkes af en hovedmotor 32 over et ikke på tegningen nærmere vist remtræk.20 Now with particular reference to FIG. 1, the plastic film web 2, which comes from a film not shown in the drawing, is fed into the top of the machine where it runs around a bypass roll 3 to a cooling roll 4 which cools the still hot foil so that it can be wound in rolls. . From the cooling roll 4, the foil goes around a dance roller 5, which regulates the speed of the web, so that there is equal tension in it, and from there the foil web 2 goes down to a stretch and smooth roll 6 which, as the name says, stretches and smooths the foil. From here, the foil web 2 goes up to a coil roll 7, the web being pressed against by a roll roller 8 arranged 5 so that with an air cylinder 9 the roll roll 8 can be swung away to facilitate the insertion of a new web 2. The various rollers is pulled by a main motor 32 over a belt drive not shown in the drawing.

Foliebanen 2 opvikles normalt på et paprør, der er skub- 10 bet ind over en spolestang 10 som indikeret i fig. 3.The foil web 2 is usually wound on a cardboard tube pushed into a coil rod 10 as indicated in FIG. Third

Spolestangen 10 hviler frit roterbar med enderne i en kløft i enderne af hver sin føringsarm 11 monteret frit svingbar på stelendernes 1 yderside. På stelendernes kant, der ligesom danner et bord, er der en krummet fø- 15 ringsbane 12, hvorpå spolestangen 10 hviler med sine ender. I takt med rullens voksende diameter, efterhånden som opviklingen skrider frem, presses spolestangen 10 længere udefter på føringsbanen 12, der har en sådan form, at trykket, hvormed rullen hviler mod spolevalsen 20 7, forbliver nogenlunde konstant. Når det ønskede antal meter folie er opviklet, hvilket kan ske som en aftast-ning af rullens diameter eller på anden kendt vis, startes et programværk fra en forvalgstæller. Programværket aktiverer korte ludtcylindre 14 ved føringsarmene 11, 25 ligesom det starter en bremsemotor 33,- der drejer en viderespolingsvalse 27 op mod rullen, der sammen med cylindrene 14 skubber rullen væk fra spolevalsen 7. Vi-derespolingsvalsen 27 er en drevet valse, som ved sin påvirkning mod rullen holder den i fortsat rotation til 30 stadig opvikling af den fremførte foliebane 2. Når foliebanen 2 er overskåret, aktiverer programværket lange luftcylindre 13 ved føringsarmene 11 og skubber den færdige rulle helt ud til enden af føringsbanen 12 146684 5 og over på et sæt aflæggerarme 15, der er monteret på stelendernes 1 inderside. Disse aflæggerarme 15 er i forbindelse med hver sin ikke på tegningen vist hydraulikcylinder, hvor olien fra undersiden af stemplet 5 drøvles væk. Når aflæggerarmene 15 er i bund fjernes rul len, og olien presses tilbage ved lufttryk, og aflæggerarmene 15 hæves til udgangsstilling.The coil rod 10 rests freely rotatable with the ends of a gap at the ends of each guide arm 11 mounted freely pivotally on the outside of the frame ends 1. On the edge of the frame ends, which form a table, there is a curved guide path 12 on which the bobbin rod 10 rests with its ends. As the roll diameter increases as the winding progresses, the bobbin rod 10 is pressed further outwardly on the guide web 12, which is of such a shape that the pressure with which the roll rests on the bobbin roll 20 7 remains approximately constant. When the desired number of meters of foil is wound up, which can be done as a scan of the diameter of the roll or in another known way, a program is started from a preselection counter. The program activates short solder cylinders 14 at the guide arms 11, 25 just as it starts a brake motor 33 rotating a rewind roller 27 against the reel which, together with the cylinders 14, pushes the reel away from the reel roller 7. The winding reel 27 is a driven roller. its impact against the roller, it keeps in continuous rotation for 30 the winding of the conveyed film web 2. When the film web 2 is cut, the program activates long air cylinders 13 at the guide arms 11 and pushes the finished roll all the way to the end of the guide web 12 and over. a set of deposition arms 15 mounted on the inside of the frame ends 1. These discharge arms 15 are in connection with each not hydraulic cylinder shown in the drawing, where the oil from the underside of the piston 5 is swirled away. When the deposition arms 15 are in the bottom, the roller is removed and the oil is pushed back at air pressure and the depositing arms 15 are raised to the starting position.

Med særlig reference til fig. 3 skal et skift mellem en færdig rulle og opstart af en ny rulle forklares i 10 det følgende.With particular reference to FIG. 3, a change between a completed roll and the start of a new roll must be explained in the following.

De nye spolestænger 10 sidder i et magasin 16 i form af et kulissestyr anbragt på hver stelende 1 umiddelbart over spolevalsen 7. Under opviklingen holdes spolestængerne 10 oppe i magasinet af en nedlæggerkurve 15 17 anbragt i hver ende på spolevalsens 7 akseltap.The new bobbin rods 10 are seated in a magazine 16 in the form of a backdrop mounted on each frame 1 immediately above the bobbin roll 7. During winding, the bobbin bars 10 are held up in the magazine by a shutter curve 15 17 located at each end of the bobbin roll 7 shaft.

Samtidig med at en rulle skubbes væk fra spolevalsen 7, drejer nedlæggerkurverne 17 for at hente en ny spolestang 10. Drejningen foretages med bremsemotoren 33 og samtidig med viderespolingsvalsens 27 drejning, 20 idet beslagene 24, hvori denne er lejret, er fast forbundet med nedlæggerkurverne 17.While pushing a roller away from the spool roll 7, the shutter curves 17 rotate to retrieve a new spool rod 10. The rotation is carried out with the brake motor 33 and at the same time as the spin of the rewind roll 27, 20, the brackets 24 in which it is mounted are firmly connected to the shutter curves 17 .

Ved drejningen falder den nederste spolestang 10 ned på et lavere parti på nedlæggerkurverne 17, idet der dog samtidig med bremsemotorens 33 igangsætning er akti-25 veret en luftcylinder 21 via programværket, og hvorpå der sidder holdepaler 22, der griber den næstneder-ste spolestang og hindrer spolestængerne i at falde ned fra magasinet 16. I nedlæggerkurverne 17 er der et indhak 23, hvori spolestangen 10 falder ned, når indhakket 30 23 er drejet hen under magasinet 16. Programværket stop per bremsemotoren 33, når nedlæggerkurverne 17 har nået 146684 6 topstillingen. Mellem beslagene 24, der bærer videre-spolingsvalsen 27, er der anbragt en savtandformet kniv 25, og bag kniven 25 er beliggende et rør 34 med et antal luftdyser 26, der blot er nogle huller for-5 delt over hele knivens længde 25. Kniven 25, der udgøres af et almindeligt grovtandet savblad, er fastgjort til røret, idet det er fastklemt mellem to jernlister 35 ved hjælp af bolte, hvor den ene jernliste er fast-svejset til røret. Desuden er der en mekanisme, der 10 aktiveres, idet den nye spolestang 10 falder ned i nedlæggerkurvernes indhak 23 og svinger kniven 25 op fra stillingen, hvor den er drejet sammen med videre-spolingsvalsen 27 og op. Drejningen af kniven sker ved kædetræk, idet der er lagt en kæde (ikke vist på teg-15 ningen) om et kædehjul (ikke vist på tegningen) i forbindelse med knivarrangementet og et andet kædehjul i fast forbindelse med et tandhjul 18, der er i indgreb med en tandstang 19, der sidder i forlængelse af en luftcylinder 20. Ved aktivering af luftcylinderen 20 20 skyder tandstangen 19 frem og drejer over kædetrækket kniven op og hugger foliebanen over i ét nu. Drejningen af kniven til overskæring af foliebanen kan dog også foretages ved en direkte sammenkobling af luftcylindrene og kniven. Aktiveringen af luftcylinderen 25 foretages med en mikroafbryder, der sidder på nedlæggerkurverne og påvirkes af den nye spolestang, idet den falder ned fra magasinet. I overskæringsøjeblikket åbnes der desuden for en ventil i tilgangen til luftdyserne 26, så der blæser kraftige luftstråler mod den 30 overskårne folieende og fører folieenden opad og omkring spolestangen 10. For at opnå en tilstrækkelig styrke i luftstrålerne benyttes der trykluft, her fra et ikke på tegningen vist trykluftreservoir, og der blæses samtidig luft ind i begge ender af røret 34.During rotation, the lower bobbin rod 10 falls on a lower portion of the shutter curves 17, however, at the same time as the start of the brake motor 33, an air cylinder 21 is activated via the program network, and there are retaining pawls 22 gripping the next lower bobbin and prevents the bobbin rods from falling down from the magazine 16. In the shutter curves 17 there is a notch 23, in which the bobbin rod 10 drops when the notch 30 23 is rotated below the magazine 16. The program stops per brake motor 33 when the shutter curves 17 have reached the top position. . Between the brackets 24 carrying the rewind roller 27 is a sawtooth-shaped knife 25, and behind the knife 25 is a pipe 34 having a plurality of air nozzles 26, which are just a few holes distributed over the entire length of the knife 25. The knife 25, which is a generally coarse-toothed saw blade, is attached to the tube, being clamped between two iron strips 35 by means of bolts, one iron strip being welded to the tube. In addition, there is a mechanism 10 actuated, as the new bobbin rod 10 falls into the notch 23 of the shutter curves and pivots the knife 25 from the position where it is rotated with the forward bobbin 27 and up. The blade is rotated by a chain pull, with a chain (not shown in the drawing) about a sprocket (not shown in the drawing) in connection with the knife arrangement and another sprocket in fixed connection with a sprocket 18 which is in the engagement with a rack 19 which is in extension of an air cylinder 20. Upon activation of the air cylinder 20 20, the rack 19 shoots forward and rotates over the chain pull knife and cuts the film web into one now. However, the rotation of the blade for cutting the film web can also be done by a direct connection of the air cylinders and the knife. The activation of the air cylinder 25 is effected by a microswitch that sits on the shutter curves and is influenced by the new coil rod as it descends from the magazine. At the cut-off moment, a valve is also opened in the access to the air nozzles 26, so that strong air jets blow against the 30 cut film end and guide the foil end up and around the coil rod 10. In order to obtain sufficient strength in the air jets, compressed air is used, here from a the drawing shows a compressed air reservoir and at the same time air is blown into both ends of the pipe 34.

Endvidere findes en anden mekanisme, som hjælper til med at vikle folienden om spolestangen 10. Denne består af et forholdsvis stort antal lodret anbragte remme 28 forneden lagt omkring en omløbsvalse 29 og for-5 oven lagt om en drivvalse 30 drevet af en elektromotor 31 (se fig. 2). Omløbsreningen af remmene 28 er den samme som for spolevalsen 7, så folieenden i begge tilfælde vikles samme vej om spolestangen 10. Den neder-ste ende af remmene 28 er anbragt i umiddelbar nærhed 10 af spolevalsen 7 (se fig. 3), så den nye spolestang 10, der frigøres fra magasinet 16, kommer til at ligge op ad remmene 28 og derved sættes i rotation, samtidig med at den opad blæste folieende fanges, gribes og vikles om spolestangen 10. Remmene 28 er kun i gang, så længe 15 den nye spolestang 10 sættes i. Herefter starter programværket bremsemotoren 33 med modsat omdrejningsretning og nedlæggerkurverne 17, drejer tilbage til udgangsstilling førende den nye spolestang 10 med sig og afleverer den i føringsarmen 11, der i mellemtiden 20 er vendt tilbage til udgagnsstilling. Når nedlæggerkurverne 17 er i udgangsstilling igen, trækkes holdepalen 22 væk, og spolestængerne i magasinet 16 hviler igen på nedlæggerkurverne 17. Herefter er de forskellige elementer reverseret til udgangsstilling klar 25 til et nyt spolestangsskifte.Further, there is another mechanism which helps to wrap the foil end about the bobbin rod 10. This consists of a relatively large number of vertically disposed belts 28 located below a by-pass roller 29 and above 5 by a drive roller 30 driven by an electric motor 31 ( see Fig. 2). The bypass cleaning of the straps 28 is the same as that of the spool roll 7, so that in both cases the foil end is wound the same way around the spool rod 10. The lower end of the straps 28 is disposed in close proximity 10 of the spool roll 7 (see Fig. 3). new bobbin rod 10, released from magazine 16, will line up with straps 28 and thereby rotate while catching, gripping and wrapping the upwardly wound foil end 10. straps 28 are in operation only for as long as 15 the new coil rod 10 is inserted. The program then starts the brake motor 33 with the opposite direction and the shutter curves 17, returns to the starting position leading the new coil rod 10 with it and delivers it in the guide arm 11, which in the meanwhile 20 has returned to the output position. When the shutter curves 17 are in the starting position again, the holding pawl 22 is pulled away and the bobbin rods in the magazine 16 are resting again on the shutter curves 17. Thereafter, the various elements are reversed to the starting position ready 25 for a new bobbin shift.
