Description
l0 l5 20 25 30 (J1 ...a U¶ Ä) OD Ü\ behandling, tomatpuré, såser osv. Sådana produkter förpackas i förpackningar som framställs från ett dessförinnan, steriliserat eller sterilbehandlat förpackningsmaterial. l0 l5 20 25 30 (J1 ... a U¶ Ä) OD Ü \ treatment, tomato puree, sauces, etc. Such products are packaged in packages made from a previously sterilized or sterile-treated packaging material.
Ett typiskt exempel på ett sådant slag av förpackning är den tetraederformade förpackningsbehållare för flytande eller hållbara livsmedelsprodukter, som är känd genom namnet TETRA CLASSIC ASEPTIC (registrerat varumärke), vilken framställs genom att vikning och försegling av ett vävformat, laminerat förpackningsmaterial. Det laminerade förpackningsmaterialet innefattar ett stödlager, som är framställt av exempelvis fibröst material såsom papper, som på ömse sidor är klätt med ett termo- plastiskt material såsom polyetylen. På den sida av det laminerade förpackningsmaterialet som är avsedd att komma i kontakt med livsmedelsinnehållet i förpackningen, finns det också ett lager med barriärmaterial, såsom exempelvis aluminiumfolie, som också är överdraget av ett termoplastiskt material.A typical example of such a type of packaging is the tetrahedral packaging container for liquid or durable food products, known as TETRA CLASSIC ASEPTIC (registered trademark), which is made by folding and sealing a woven, laminated packaging material. The laminated packaging material comprises a backing layer, which is made of, for example, fibrous material such as paper, which is lined on both sides with a thermoplastic material such as polyethylene. On the side of the laminated packaging material which is intended to come into contact with the food content of the package, there is also a layer of barrier material, such as for instance aluminum foil, which is also coated with a thermoplastic material.
För att framställa tetraederformade förpackningsbehållare av ovan nämnda slag, matas påfyllnings- eller förpackningsmaskiner med laminerat förpackningsmaterial i vävform. Förpackningsamterial- väven steriliseras i förpackningsmaskinen genom applicering av en kemisk steriliseringsagent som exempelvis väteperoxidlösning. Vid fullbordande av steriliseringen, avlägsnas steriliseringsagenten från ytorna på förpackningsmaterialet, exempelvis kan den förångas genom uppvärmning.To produce tetrahedral packaging containers of the kind mentioned above, filling or packaging machines are fed with laminated packaging material in weave form. The packaging material fabric is sterilized in the packaging machine by applying a chemical sterilizing agent such as hydrogen peroxide solution. Upon completion of the sterilization, the sterilizing agent is removed from the surfaces of the packaging material, for example, it may be evaporated by heating.
Det steriliserade förpackningsmaterialet vikes och förseglas longitudinellt till att bilda en tub son1 fylls med, en steril- behandlad livsmedelsprodukt. Tuben passerar mellan två par av ändlösa kedjor som uppbär förseglingsmedel som griper och förseglar tuben emellan dem genom att producera ett första förseglingsband av material som utsträcker sig i en första 10 15 20 25 30 (I1 --8 (J1 NJ (IJ O\ LU riktning, och ett andra förseglingsband av material som utsträcker sig vinkelrätt i förhållande till den första riktningen. De resulterande förpackningarna har en tetraedrisk form. De förseglade förpackningsmaterialbanden skärs mellan på varandra följande, fyllda och förseglade tetraedraformade förpackningar.The sterilized packaging material is folded and sealed longitudinally to form a tube son1 filled with, a sterile-treated food product. The tube passes between two pairs of endless chains carrying sealing means which grip and seal the tube between them by producing a first sealing band of material extending in a first 10 15 20 25 30 (I1 --8 (J1 NJ (IJ O \ LU)). direction, and a second sealing strip of material extending perpendicular to the first direction.The resulting packages have a tetrahedral shape.The sealed packaging material strips are cut between successive, filled and sealed tetrahedral packages.
Ett exempel på detta slag av förpackningsmaskin är påfyllningsmaskinen TETRA CLASSIC ASEPTIC (registrerat varumärke), som framställs av Tetra Pak Stålvall i Partille, Sverige.An example of this type of packaging machine is the filling machine TETRA CLASSIC ASEPTIC (registered trademark), which is manufactured by Tetra Pak Stålvall in Partille, Sweden.
DET TEKNISKA PROBLEMET Ofta är ett mönster vilket förpackningsmaterialväven, för förhållande till tryckt på positionen måste styras i förseglingsbackarna, dvs. bildandet av behållarens två ytterändar.THE TECHNICAL PROBLEM Often a pattern is which the packaging material fabric, in relation to the printed position, must be guided in the sealing jaws, ie. the formation of the two outer ends of the container.
Vävmaterialet kanske också skall förses med sugrörsöppningar eller perforeringar för vilka positionen måste styras i förhållande till förseglingsbackarna.The weave material may also need to be provided with straw openings or perforations for which the position must be controlled relative to the sealing jaws.
För att möjliggöra denna positionering i förhållande till förseglingsbackarna, har ett lnotoriserat rullsystenl använts för att variera inmatningen av Väven. Emellertid ger ett sådant slag av system upphov till en del bortslösade förpackningar, dvs. förpackningar som fylls och förseglas, men som måste slängas eftersom mönstret som är tryckt på förpackningsmaterialet, sugrörsöppningen eller perforeringen ej hamnar på rätt ställe på den färdiga förpackningen. Det motoriserade rull-mönster- korrigeringssystemet ("design correction system") är inte heller praktiskt att tillämpa när förpackningsbehàllare som har olika volym skall produceras, eftersom detta system genererar spänningar i vävmaterialet som kan leda till skadade behållare, speciellt om det handlar om behållare med stor volym. Ovan beskrivna mönster- ett visst avstånd ifrån de korrigeringssystem är beläget på behållarskapande förseglingsbackarna och det är inte välanpassat 10 15 20 25 30 E-iC *Qå JIJ UU för snabba och exakta korrektioner som svar på små variationer längs materialväven.To enable this positioning in relation to the sealing jaws, a licensed rolling system has been used to vary the input of the fabric. However, such a type of system gives rise to some wasted packaging, ie. packages that are filled and sealed, but must be discarded because the pattern printed on the packaging material, the straw opening or the perforation does not end up in the right place on the finished package. The motorized design correction system is also not practical to apply when producing packaging containers of different volumes, as this system generates stresses in the fabric material which can lead to damaged containers, especially in the case of containers with large volume. The pattern described above- a certain distance from the correction systems is located on the container-creating sealing jaws and it is not well adapted 10 15 20 25 30 E-iC * Qå JIJ UU for fast and precise corrections in response to small variations along the material fabric.
Problemet med mönsterkorrigering är att det är ännu mera uttalat under uppstartningen av maskin för framställning av förpacknings- behållare, när förseglingsbackarnas arbetande måste synkroniseras med materialväven, men det finns också normala variationer inom materialvävstryckningsprocessen som måste korrigeras för under normal drift.The problem with pattern correction is that it is even more pronounced during the start-up of the machine for making packaging containers, when the working of the sealing jaws must be synchronized with the material fabric, but there are also normal variations in the material fabric printing process that must be corrected for during normal operation.
Ovan nämnda sugrörsöppningar eller perforeringar görs normalt i materialvävstuben vid förpackningsmaskinen genom en anordning som måste adderas till maskinen. Det skulle vara mera fördelaktigt om dessa operationer kunde utföras under processen då förpackningsmaterialväven lamineras och vid tryckning på den.The above-mentioned suction tube openings or perforations are normally made in the material web tube at the packaging machine by a device which must be added to the machine. It would be more advantageous if these operations could be performed during the process when the packaging material web is laminated and when printed on it.
MÅLEN MED UPPFINNINGEN Det finns ett behov av en förbättrad mönsterkorrigeringsmetod och en anordning för att utföra denna metod. Således är ett av målen med uppfinningen att ange ett sådant förfarande och en sådan anordning som löser ovan beskrivna problem på ett enkelt och effektivt sätt.OBJECTS OF THE INVENTION There is a need for an improved pattern correction method and apparatus for performing this method. Thus, one of the objects of the invention is to provide such a method and a device which solves the problems described above in a simple and efficient manner.
Ett annat mål är att göra det möjligt att utföra mönsterkorrektion för behållare som har en stor volym.Another goal is to make it possible to perform pattern correction for containers that have a large volume.

DETALJERAD BESKRIVNING AV UPPFINNINGEN Förseglingsbacken 10 som visas i figur 1 innefattar en huvudkropp 11 till vilken ett par av volymdefinierande avsnitt 12 är anslutna försedd med en via fastsättningsmedel 13. Huvudkroppen 11 är anslutning 14 för förbindelse med en ändlös kedja (ej visad i ritningarna), som» driver ett antal förseglingsbackar i synkron rörelse längs den tubformiga materialväven 15 (se figur 2 och 3), väsentligen överensstämmande med känd teknik inom området.DETAILED DESCRIPTION OF THE INVENTION The sealing jaw 10 shown in Figure 1 comprises a main body 11 to which a pair of volume defining sections 12 are connected provided with a via fastener 13. The main body 11 is connection 14 for connection to an endless chain (not shown in the drawings). driving a number of sealing jaws in synchronous motion along the tubular fabric 15 (see Figures 2 and 3), substantially in accordance with prior art.
Avslutningen 14 bildar en lagringspunkt för förseglingsbacken med avseende på den ändlösa kedjan. En liten styrningsrulle 16 är belägen på motsatt sida av förseglingsbacken. Denna styrrulle 16 används för att styra inàtrörelsen för förseglingsbacken i processen för att göra nästa, påföljande försegling i den tubformiga materialväven. Huvudkroppen 11 är försedd med en eftergivlig tryckyta 11a som samverkar med en motsvarande motsatt förseglingsback som är försedd med induktionsuppvärmnings- förseglingsmedel. En större styrningsrulle 17 är anordnad på huvudkroppen 11 för att tillhandahålla stöd för förseglingsbacken under den slutliga förseglingsfasen.The end 14 forms a storage point for the sealing jaw with respect to the endless chain. A small guide roller 16 is located on the opposite side of the sealing jaw. This guide roller 16 is used to control the inward movement of the sealing jaw in the process of making the next, subsequent seal in the tubular fabric. The main body 11 is provided with a resilient pressure surface 11a which cooperates with a corresponding opposite sealing jaw which is provided with induction heating sealing means. A larger guide roller 17 is provided on the main body 11 to provide support for the sealing jaw during the final sealing phase.
Figurerna 2 och 3 visar den första delen av denna förseglingsfas, där paret av nmtsatta förseglingsbackar 10 bringas samman från motsatta riktningar mot den longitudinellt förseglade vätskefyllda förpackningsmaterialtuben 15. Banan för varje förseglingsback 10 styrs av ett kamorgan 18 som är monterat på maskinramen 19 via ett första respektive ett andra kopplingsmedel 20 och 21. Kamorganet 10 15 20 25 30 Crn Cr1 P4) Cm <ï~ 18 är försett med en kamyta 18a som samverkar med styrningsrullen 16 på förseglingsbacken 10 när de två förseglingsbackarna bringas ihop.Figures 2 and 3 show the first part of this sealing phase, where the pair of inserted sealing jaws 10 are brought together from opposite directions to the longitudinally sealed liquid-filled packaging material tube 15. The web of each sealing jaw 10 is guided by a cam member 18 mounted on the machine frame 19 via a first respectively, a second coupling means 20 and 21. The cam means 10 is provided with a cam surface 18a which cooperates with the guide roller 16 on the sealing jaw 10 when the two sealing jaws are brought together.
Det första kopplingsmedlet 20 är anslutet till kamorganet 18 via en öppning 22 (se fig. 4) som är oval, så att den medger ett litet rörelsespel på denna ände av kamorganet. På motsatta änden av kamorganet, bildar det andra kopplingsmedlet en fast lagringspunkt 18. Kamorganet är försett med en tryckstång 23 som vilar på ett manövreringsorgan 24 som är stelt monterat på maskinramen 19. När eller deaktiveras, vrider manövreringsorganet 24 aktiveras tryckstången kamorganet runt lagringspunkten 21, så långt som öppningen 22 på den motsatta änden av kamorganet medger. På detta sätt förändras kamytans rampvinkel 18a för styrningsrullen 16.The first coupling means 20 is connected to the cam member 18 via an opening 22 (see Fig. 4) which is oval, so that it allows a small play of movement on this end of the cam member. At the opposite end of the cam means, the second coupling means forms a fixed bearing point 18. The cam means is provided with a push rod 23 resting on an actuator 24 rigidly mounted on the machine frame 19. When or deactivated, the actuator 24 rotates the push rod cam means around the bearing point 21. as far as the opening 22 on the opposite end of the cam member allows. In this way, the ramp angle 18a of the cam surface of the guide roller 16 changes.
En fotocell 25 är belägen nära materialvävstuben 15 så att den kan registrera en serie av indexmarkeringar 26 som är tryckta på förpackningsmaterialväven. Varje markering läses av fotocellen 25 och informationen överförs till en maskinstyrenhet via en avkodare 27, så positionen för förseglingsbackarna 10. Denna information behandlas att positionen för markeringen 26 kan jämföras med och ett beslut tas om att göra en mönsterkorrigering om indexmarkeringen inte är i överensstämmelse med förseglingsbackarnas position. Avkodaren 27 är elektriskt förbunden med en luftventil som samtidigt aktivierar eller deaktiverar de två manövreringsorganen 24.A photocell 25 is located near the fabric web tube 15 so that it can register a series of index marks 26 printed on the packaging fabric web. Each mark is read by the photocell 25 and the information is transmitted to a machine controller via a decoder 27, so the position of the sealing jaws 10. This information is processed that the position of the mark 26 can be compared with and a decision is made to make a pattern correction if the index mark does not conform. the position of the sealing jaws. The decoder 27 is electrically connected to an air valve which simultaneously activates or deactivates the two actuators 24.
Figur 2 visar en första driftsmod, utan mönsterkorrigering, där de två centrala eftergivliga delarna lla på förseglingsbackarna bringas ihop i det närmaste parallellt. Manövreringsorgan 25 aktiveras i denna driftsmod och den branta kamytsrampvinkeln styr styrningsrullarna 16, så att de eftergivliga delarna llb på förseglingsbackarna bringas ihop nästan omedelbart. 10 15 20 25 30 LH nå: CH 5 CD (JN Figur 3 visar en andra driftsmod, med mönsterkorrigering, där de två centrala, eftergivliga delarna lla pà förseglingsbackarna bringas ihop vid en ömsesidig vinkel. Denna vinkel är resultatet av deaktiveringen av manövreringsorganen 24, som reducerar rampvinkeln för kamytan för styrningsrullarna 16. I denna driftsmod, bringas förseglingsbackarna samman vid en punkt som är förflyttad ett visst avstånd uppströms, längs materialvävstuben.Figure 2 shows a first mode of operation, without pattern correction, where the two central resilient parts 11a on the sealing jaws are brought together almost in parallel. Actuators 25 are activated in this mode of operation and the steep camshaft ramp angle guides the guide rollers 16, so that the resilient parts 11b on the sealing jaws are brought together almost immediately. 10 15 20 25 30 LH reach: CH 5 CD (JN Figure 3 shows a second mode of operation, with pattern correction, where the two central, resilient parts 11a on the sealing jaws are brought together at a mutual angle. This angle is the result of the deactivation of the actuators 24, which reduces the ramp angle of the cam surface of the guide rollers 16. In this mode of operation, the sealing jaws are brought together at a point which is moved a certain distance upstream, along the fabric web.
När de två förseglingsbackarna 10 bringas att vara parallella nedströms i förhållande till punkten som illustreras i figur 3, dras materialvävtuben i utdelningsriktningen, så att mer material dras förbi de eftergivliga delarna lla som utför nästa, påföljande försegling.When the two sealing jaws 10 are made to be parallel downstream of the point illustrated in Figure 3, the material web tube is pulled in the distribution direction, so that more material is pulled past the resilient parts 11a which perform the next, subsequent sealing.
Avståndsvariationen mellan figurerna 2 och 3 illustreras med hjälp av pilarna 28 respektive 29. Eftersom det finns två par av förseglingsbackar som är involverade i processen att bilda varje förpackningsbehållare, är det möjligt att variera ovan beskrivna mönsterkorrigeringsprocess i tre steg genom att använda: 0 båda paren med förseglingsbackar, 0 ett par med förseglingsbackar, eller 0 inget av de två paren med förseglingsbackar.The distance variation between Figures 2 and 3 is illustrated by means of arrows 28 and 29, respectively. Since there are two pairs of sealing jaws involved in the process of forming each packaging container, it is possible to vary the pattern correction process described above in three steps by using: 0 both pairs with sealing jaws, 0 a pair with sealing jaws, or 0 neither of the two pairs with sealing jaws.
Detta betyder att den operativa räckvidden för mönsterkorrigering blir jämförelsevis stor. Ovan beskrivna mönsterkorrigeringssystem använder ett PÅ/AV manövreringsorgan 24, men det skulle vara möjligt att använda ett manövreringsorgan som skulle kunna flytta sig till en eller flera positioner mellan de två ytterlägena. På detta sätt skulle det vara möjligt att styra mönsterkorrigerings- systemet ännu mera exakt. lO 15 20 25 30 :_401- AA! kflk 'lklk Jia) LUU 10 Konceptet med föreliggande uppfinningen är givetvis också tillämpbart på andra slag av förpackningsbehållare för hällbara livsmedelsprodukter, exempelvis för förpackningsbehållare som är kända genom namnet TETRA BRIK (registrerat varumärke) eller liknande.This means that the operational range for pattern correction is comparatively large. The pattern correction system described above uses an ON / OFF actuator 24, but it would be possible to use an actuator which could move to one or more positions between the two outer positions. In this way, it would be possible to control the pattern correction system even more precisely. lO 15 20 25 30: _401- AA! k fl k 'lklk Jia) LUU The concept of the present invention is of course also applicable to other types of packaging containers for pourable food products, for example for packaging containers known by the name TETRA BRIK (registered trademark) or the like.
Ovan beskrivna maskin för förpackning av flytande eller hällbara livsmedelsprodukter, som inkorporerar mönsterkorrigeringssystemet enligt uppfinningen, är också mångsidigare än dagens förpackningsmaskiner för flytande livsmedel av formen fyll på och försegla. Normalt måste varje flytande livsmedelsförpacknings- maskin genomgå en väsentlig ombyggnad varje gång som man önskar framställa behållare som har en annorlunda volym. Betydande förändringar måste göras i mönsterkorrigeringssystemet. Detta innebär en betydande spilltid varje gång som en volymförändring göres. Å andra sidan, i maskinen som inkorporerar mönsterkorrigeringssystemet enligt uppfinningen, genom att ersätta förseglingsbackarna 10 och de volymdefinierande avsnitten 12 med förseglingsbackar och volymdefinierande avsnitt 12 som har annorlunda storlek, kan samma maskin användas för att framställa behållare från en vätskefylld longitudinellt förseglad förpackningsmaterialtub 15 Ined en annan diameter, för att göra behållare som har en annorlunda volym. Mönsterkorrigeringssystemet justeras lätt för att säkerställa korrekt inåtrörelse för behållarna med ny volym på det sätt som beskrivits i det föregående. Detta betyder att stilltiden som krävs för att ändra volymen av förpackningarna som skall framställas kraftigt reduceras såsom jämfört med standardmaskiner. Följaktligen är den ovan beskrivna maskinen som inkorporerar mönsterkorrigerings- enligt systemet uppfinningen i viss grad volymflexibel, och mångsidigare vid drift.The liquid or pourable food product packaging machine described above, which incorporates the pattern correction system of the invention, is also more versatile than today's liquid food packaging machines of the form fill and seal. Normally, each liquid food packaging machine must undergo a significant rebuild every time it is desired to produce containers that have a different volume. Significant changes must be made in the pattern correction system. This means a significant waste time every time a volume change is made. On the other hand, in the machine incorporating the pattern correction system of the invention, by replacing the sealing jaws 10 and the volume-defining sections 12 with sealing jaws and volume-defining sections 12 having different sizes, the same machine can be used to produce containers from a liquid-filled longitudinally sealed packaging material. different diameter, to make containers having a different volume. The pattern correction system is easily adjusted to ensure correct inward movement of the new volume containers in the manner described above. This means that the downtime required to change the volume of the packages to be produced is greatly reduced as compared to standard machines. Accordingly, the machine described above incorporating the pattern correction according to the system invention is to some extent volume flexible, and more versatile in operation.
) CH ...än LH N CI> CT\ ll Uppfinningen är inte på något sätt begränsad till de visade utföringsexemplen utan den kan varieras på ett antal sätt inom ramen för vidhängande patentkrav. Exempelvis kan medlen för att styra banan för förseglingsbackarna designas på ett annorlunda sätt.The invention is in no way limited to the exemplary embodiments shown, but it can be varied in a number of ways within the scope of the appended claims. For example, the means for guiding the path of the sealing jaws can be designed in a different way.
