Description

Die Erfindung betrifft eine Folienschlauchverpackungsmaschine, umfassend zwei Fƶrdervorrichtungen mit zwei diesen jeweils zugeordneten portalƤhnlichen Formschultern, welche jeweils dafĆ¼r vorgesehen sind, eine diesen jeweils zugefĆ¼hrte Folienbahn derart in Fƶrderrichtung der jeweiligen Fƶrdervorrichtung umzulenken, dass in Fƶrderrichtung hinter den Formschultern ein jeweiliger tunnelƤhnlicher Folienschlauch als Verpackung geformt wird, wobei die zwei Fƶrdervorrichtungen dafĆ¼r vorgesehen sind, Gruppen von auf diesen befindlichen zu verpackenden Verbrauchsprodukten, insbesondere Tissueprodukten, mit einer vorgegebenen Vorschubgeschwindigkeit durch die jeweilige Formschulter in den jeweiligen tunnelƤhnlichen Folienschlauch zu bewegen, wobei sich dieser dabei mit derselben Vorschubgeschwindigkeit bewegt wie die Verbrauchsprodukte und wobei die zwei Fƶrdervorrichtungen lƤngs einer gemeinsamen Ebene parallel zueinander angeordnet sind.The invention relates to a tubular film packaging machine, comprising two conveying devices with two associated each portal-like forming shoulders, which are each intended to redirect a respective supplied film web in the conveying direction of the respective conveyor, that in the conveying direction behind the forming shoulders a respective tunnel-like film tube is formed as a package in which the two conveying devices are intended to move groups of consumable products, in particular tissue products, to be packed thereon at a predetermined feed rate through the respective forming shoulder into the respective tunnel-like film tube, the latter moving at the same feed rate as the consumable products and the two conveyors are arranged along a common plane parallel to each other.

Es ist allgemein bekannt, dass Verbrauchsprodukte vergleichsweise geringwertige Produkte des tƤglichen Bedarfs sind. Verbrauchsprodukte mĆ¼ssen, bevor sie in den Handel kommen, entsprechend verpackt werden. Typische Vertreter von Verbrauchsprodukten sind Tissueprodukte, insbesondere Rollenware wie KĆ¼chenpapierrollen oder Toilettenpapierrollen, die als Rollengruppen in Folienbeutel verpackt werden, beispielsweise in VerpackungsgrĆ¶ĆŸen von 1 x 3, 1 x 4, 2 x 3, 2 x 4, 2 x 5, 3 x 3, 3 x 4 oder 3 x 5 Rollen. Ein typischer Rollendurchmesser betrƤgt beispielsweise ca. 10 - 15cm, bei einer typischen LƤnge von ca. 10cm oder auch 25cm.It is well known that consumer products are comparatively low value everyday products. Consumables must be packaged appropriately before being sold. Typical representatives of consumer products are tissue products, in particular rolls such as kitchen rolls or toilet paper rolls, which are packed as roll groups in foil bags, for example in packaging sizes of 1 x 3, 1 x 4, 2 x 3, 2 x 4, 2 x 5, 3 x 3, 3 x 4 or 3 x 5 rolls. A typical roll diameter is for example about 10 - 15cm, with a typical length of about 10cm or 25cm.

Unter Tissueprodukten sind aber auch sonstige Hygieneartikel sowie beispielsweise gefaltete und/oder gestapelte Produkte wie TaschentĆ¼cher oder Servietten zu verstehen, welche in analoger Weise gruppenweise zu verpacken sind, bevor sie in den Endhandel gelangen. Tissueprodukte sind Verbrauchsprodukte mit im Vergleich zu GebrauchsgĆ¼tern recht geringen Herstellungskosten, so dass der Aufwand, welcher fĆ¼r deren Verpackung zu betreiben ist, zu minimieren ist.Tissue products, however, also include other hygiene articles and, for example, folded and / or stacked products such as handkerchiefs or napkins, which are to be packaged in groups in an analogous manner before they reach the retail outlet. Tissue products are consumer products with relatively low manufacturing costs compared to consumer goods, so that the effort that has to be done for their packaging is to be minimized.

Um dem Endverbraucher eine besonders einfache Handhabung von derart verpackten Tissueprodukten zu ermƶglichen, ist in der Regel ein Tragegriff als Teil des Folienbeutels vorgesehen, mittels welchem der Folienbeutel mit den darin verpackten Rollen besonders einfach getragen werden kann. Hierbei ist zu beachten, dass ein derartiger Tragegriff mit entsprechendem Trageloch zur sicheren Handhabung des Folienbeutels entsprechend stabil ausgefĆ¼hrt sein muss, um ein DurchreiƟen zu vermeiden. Eine doppelte MaterialstƤrke des Folienmaterials ist hierbei oft nicht ausreichend.In order to allow the end user a particularly simple handling of tissue products so packaged, usually a carrying handle is provided as part of the foil bag, by means of which the foil bag with the rolls wrapped therein can be carried particularly easily. It should be noted that such a carrying handle with a corresponding carrying hole for the secure handling of the foil bag must be designed to be stable in order to avoid tearing. A double thickness of the film material is often not sufficient.

Neben Tissueprodukten sind unter einem Verbrauchsprodukt aber auch eine Vielzahl an anderen VerbrauchgĆ¼tern zu verstehen, beispielsweise in kleinen Kartons vorverpackte Nahrungsmittel oder auch gefĆ¼llte TrinkbehƤltnisse wie Tetrapaks.In addition to tissue products are under a consumer product but also a variety of other consumer goods to understand, for example, in small boxes prepackaged foods or filled drinking containers such as Tetrapaks.

GemƤƟ dem Stand der Technik werden die entsprechenden Gruppen von Verbrauchs- beziehungsweise Tissueprodukten beim Verpackungsvorgang in einen jeweils vorgefertigten Folienbeutel geschoben, welcher im Anschluss verschweiƟt wird. Hierbei ist ein Ɯberstand der zusammenzuschweiƟenden Folienbereiche erforderlich, wobei der Ɯberstand dann nach dem VerschweiƟen abgeschnitten und als Abfall verworfen wird.According to the prior art, the corresponding groups of consumable or tissue products are pushed during the packaging process into a respective prefabricated foil bag, which is subsequently welded. In this case, a supernatant of zusammenzuschweiƟenden film areas is required, the supernatant is then cut off after welding and discarded as waste.

Als nachteilig erweist sich hierbei neben dem Materialverwurf des Ɯberstandes, dass sich eine Verpackung in vorgefertigte Folienbeutel abhƤngig von der FolienqualitƤt als schwierig und aufwƤndig erweist und zudem Bedienpersonal zum NachfĆ¼llen der Beutelstapel erforderlich ist.A disadvantage in this case, in addition to the Materialverwurf of the supernatant proves that a package in prefabricated foil bag proves to be difficult and costly depending on the film quality and also operating personnel to refill the bag stack is required.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, eine Vorrichtung und ein Verfahren anzugeben, mittels welchen ein vereinfachtes Verpacken von Verbrauchsprodukten, insbesondere Tissueprodukten, in Folienbeutel ermƶglicht ist und bei welchen der Verwurf an Verpackungsfolie reduziert ist.Based on this prior art, it is an object of the invention to provide an apparatus and a method by means of which a simplified packaging of consumer products, in particular tissue products, is made possible in foil bags and in which the Verwurf is reduced to packaging film.

Diese Aufgabe wird gelƶst durch eine Folienschlauchverpackungsmaschine der eingangs genannten Art. Diese ist dadurch gekennzeichnet, dass die beiden Formschultern derart ausgestaltet sind, dass die jeweiligen seitlichen Kantenbereiche der beiden Folienbahnen, aus denen die zwei tunnelƤhnlichen FolienschlƤuche geformt werden, in einem zwischen diesen liegenden Falzebenenbereich verlaufen, dass in dem zwischen den tunnelƤhnlichen FolienschlƤuchen befindlichen Falzebenenbereich die seitlichen Kantenbereiche der zu tunnelƤhnlichen FolienschlƤuchen geformten Folienbahnen in mehreren Folienlagen Ć¼berlappend angeordnet sind, und dass der Falzebenenbereich wenigstens zwei Folienlagen umfasst, die aus Kantenbereichen der beiden Folienbahnen gebildet sind.This object is achieved by a tubular film packaging machine of the type mentioned in the introduction. This is characterized in that the respective lateral edge regions of the two film webs from which the two tunnel-like film tubes are formed lie in a folded plane region lying between them in that in the fold plane region located between the tunnel-like film tubes, the lateral edge regions of the film webs shaped into tunnel-like film tubes are overlappingly arranged in a plurality of film layers, and in that the fold plane region comprises at least two film layers which are formed from edge regions of the two film webs.

Die Grundidee der Erfindung besteht darin, den FolienĆ¼berstand als Ausgangsbasis fĆ¼r einen Tragegriff zu verwenden. Um die benƶtigte erhƶhte StabilitƤt des Tragegriffs zu gewƤhrleisten, ist es erfindungsgemƤƟ vorgesehen, zwei parallele FolienschlƤuche aus einer jeweiligen Folienbahn zu formen, wobei deren seitliche Kantenbereiche in einem gemeinsamen Falzebenenbereich mĆ¼nden, welcher dann die Ausgangsbasis fĆ¼r einen jeweiligen Tragegriff bildet.The basic idea of the invention is to use the film supernatant as the starting point for a carrying handle. In order to ensure the required increased stability of the carrying handle, it is provided according to the invention to form two parallel film tubes from a respective foil web, wherein the lateral edge regions open in a common folded plane region, which then forms the starting base for a respective carrying handle.

Je nach Anordnung der insgesamt vier in den Falzebenenbereich mĆ¼ndenden Kantenbereiche der zwei Folienbahnen lƤsst sich mit beziehungsweise ohne Ɯberlappung in den jeweiligen Folienlagen eine verschiedene Anzahl an Folienlagen erzielen, wobei einerseits so viele Folienlagen vorhanden sein sollten, dass eine genĆ¼gend hohe StabilitƤt des daraus gebildeten Tragegriffs gewƤhrleistet ist, auf der anderen Seite jedoch ein unnƶtiger Materialverbrauch durch zu viele Folienlagen vermieden ist.Depending on the arrangement of the four edge regions of the two film webs opening into the fold plane region, a different number of film layers can be achieved with or without overlap in the respective film layers, on the one hand so many film layers should be present that ensures a sufficiently high stability of the handle formed therefrom is, on the other hand, however, unnecessary material consumption is avoided by too many layers of film.

Prinzipielles Minimum an Lagen ist zwei, wobei dann jeweils zwei Kantenbereiche der jeweiligen Folienbahnen in derselben Folienlagen mĆ¼nden, dies vorzugsweise aneinanderstoƟend, und wobei die StoƟkanten der beiden Lagen dann quer zur Fƶrderrichtung gegeneinander versetzt sind, beispielsweise um einige Zentimeter, um so eine hohe StabilitƤt nach deren VerschweiƟen zu gewƤhrleisten. Eine Anzahl an zwei Lagen wird in den meisten FƤllen jedoch keine hinreichende StabilitƤt fĆ¼r einen Tragegriff bieten, es sei denn, die Dicke der Folienbahnen insgesamt ist entsprechend hoch. Dies wĆ¼rde aber letztendlich einen zu hohen Materialeinsatz bei dem Folienbeutel bedeuten, welcher dann stabiler wƤre als in der Regel benƶtigt. Es sei an dieser Stelle aber dennoch auf die grundsƤtzliche Variante verwiesen, bei welcher die beiden Formschultern derart ausgestaltet sind, dass die jeweiligen seitlichen Kantenbereiche der beiden Folienbahnen, aus denen die zwei tunnelƤhnlichen FolienschlƤuche geformt werden, in einem zwischen diesen liegenden Falzebenenbereich verlaufen, und dass dieser genau zwei Folienlagen umfasst.The principal minimum of layers is two, wherein in each case two edge regions of the respective film webs open in the same film layers, preferably this abutting, and wherein the abutting edges of the two layers are then offset transversely to the conveying direction against each other, for example by a few centimeters, so as to ensure a high stability after the welding. However, a number of two layers will in most cases not provide sufficient stability for a carrying handle unless the thickness of the film webs as a whole is correspondingly high. However, this would ultimately mean an excessive use of material in the film bag, which would then be more stable than usually needed. However, reference should be made at this point to the basic variant, in which the two forming shoulders are configured such that the respective lateral edge regions of the two film webs from which the two tunnel-like film tubes are formed lie in a folded plane region lying between them, and this includes exactly two layers of film.

Eine weitere Variante der Anordnung der Kantenbereiche der Folienbahnen besteht darin, dass jeder Kantenbereich der beiden Folienbahnen eine komplette Lage im Falzebenenbereich bildet, womit insgesamt vier Folienlagen vorhanden sind. Je nach Foliendicke kƶnnte dies jedoch bereits eine StabilitƤt fĆ¼r einen Tragegriff bedeuten, welche hƶher als benƶtigt ist. Durch zusƤtzliche Faltung der Kantenbereiche im Falzebenenbereich lassen sich theoretisch auch mehr als vier Folienlagen realisieren.A further variant of the arrangement of the edge regions of the film webs is that each edge region of the two film webs forms a complete position in the folded plane region, with which a total of four film layers are present. Depending on the film thickness, however, this could already mean a stability for a carrying handle, which is higher than needed. By additional folding of the edge regions in the folded plane region, theoretically more than four film layers can be realized.

Bei einer Anordnung von zwei Kantenbereichen der Folienbahnen als jeweilige komplette Folienlage und von weiteren zwei Kantenbereichen in einer gemeinsamen Folienlage lassen sich insgesamt auch drei Folienlagen im gemeinsamen Falzebenbereich erzielen. Im Falle der Anordnung zweier Kantenbereiche der Folienbahnen in derselben Folienlage ist tendenziell einer minimalen StoƟlĆ¼cke gegenĆ¼ber einer Ć¼berschneidenden Ɯberlappung der Vorzug zu geben, um so eine homogene Dicke des Falzebenenbereiches zu gewƤhrleisten, wobei im Idealfall eine genaue StoƟkante vorhanden ist.In the case of an arrangement of two edge regions of the film webs as the respective complete film layer and of a further two edge regions in a common film layer, it is also possible to achieve a total of three film layers in the common fold plane region. In the case of the arrangement of two edge regions of the film webs in the same film layer, preference is given to a minimum impact gap over an overlapping overlap, so as to ensure a homogeneous thickness of the folded plane region, ideally providing an exact abutment edge.

Kernelement der erfindungsgemƤƟen Folienschlauchverpackungsmaschine sind die beiden Formschultern, welchen vorzugsweise seitlich kontinuierlich eine jeweilige Folienbahn zugefĆ¼hrt wird, die derart in Fƶrderrichtung umgelenkt wird, dass daraus ein tunnelƤhnlicher Folienschlauch geformt wird, wobei die jeweiligen beiden Kantenbereiche der beiden Folienbahnen in einen zwischen den FolienschlƤuchen liegenden gemeinsamen Falzebenenbereich mĆ¼nden. Die vertikale Hƶhe des Falzebenenbereiches liegt hierbei vorzugsweise auf halber Hƶhe der Verpackung, so dass der Tragegriff mittig liegt und die Verpackung mit den darin befindlichen Verbrauchsbeziehungsweise Tissueprodukten dann ohne Schieflage an dem Tragegriff tragbar ist.The core element of the film tubular packaging machine according to the invention are the two forming shoulders, which are preferably laterally continuously fed to a respective film web, which is deflected in the conveying direction, that from a tunnel-like film tube is formed, wherein the respective two edge regions the two film webs open into a lying between the film tubes common Falzebenenbereich. The vertical height of the folded plane region is preferably at half the height of the packaging, so that the carrying handle is in the middle and the packaging with the consumption or tissue products contained therein can then be carried on the carrying handle without imbalance.

Eine Formschulter ist im weitesten Sinne mit einem Portal vergleichbar, dessen Innenquerschnitt in etwa dem Querschnitt des herzustellenden Folienbeutels entspricht. WƤhrend des Verpackungsvorgangs wird die Folie derart von auƟen um die Formschulter umgelenkt, dass an deren Innenquerschnitt der jeweilige Folienschlauch gebildet ist, welcher idealerweise kontinuierlich in Fƶrderrichtung der Fƶrdervorrichtung bewegt wird.A forming shoulder is in the broadest sense comparable with a portal whose inner cross section corresponds approximately to the cross section of the film bag to be produced. During the packaging process, the film is deflected from the outside around the forming shoulder in such a way that the respective film tube is formed on its inner cross section, which is ideally moved continuously in the conveying direction of the conveying device.

Eine kontinuierliche Bewegung der jeweiligen FolienschlƤuche ist dadurch erreichbar, dass die zu verpackenden Gruppen oder Formationen von Verbrauchs- beziehungsweise Tissueprodukten durch die portalƤhnliche Ɩffnung der Formschulter geschoben werden, beispielsweise mittels eines Schiebers oder Mitnehmers, wobei die Fƶrdervorrichtung hinter der Formschulter oberhalb und unterhalb des Folienschlauches befindliche synchron laufende FƶrderbƤnder aufweist, zwischen welchen dann die durch die jeweilige Formschulter geschobenen und nunmehr im jeweiligen Folienschlauch befindlichen Verbrauchs- beziehungsweise Tissueprodukte eingeklemmt sind, so dass diese entsprechend zusammen und synchron mit dem Folienschlauch gefƶrdert werden.A continuous movement of the respective film tubes can be achieved by pushing the groups or formations of consumable or tissue products to be packaged through the portal-like opening of the forming shoulder, for example by means of a slider or driver, the conveyor being located behind the forming shoulder above and below the film tube synchronously running conveyor belts, between which then pushed through the respective form shoulder and now located in the respective film tube consumable or tissue products are clamped so that they are promoted together and synchronously with the film tube.

Eine Fƶrdervorrichtung kann aus mehreren hintereinander geschalteten Teilfƶrdervorrichtungen bestehen, beispielsweise FƶrderbƤndern, wobei typischerweise auch zusƤtzliche Mitnehmer vorgesehen sein kƶnnen, beispielsweise um Gruppen von Verbrauchs- beziehungsweise Tissueprodukten zu bilden.A conveyor device can consist of a plurality of sub-conveying devices connected in series, for example conveyor belts, wherein typically additional carriers can also be provided, for example to form groups of consumable or tissue products.

Derartige Mitnehmer kƶnnen in der Regel nur bis zur Vorderkante der Formschultern fahren. Um eine notwendige LĆ¼cke zwischen Gruppen von Verbrauchs- beziehungsweise Tissueprodukten herzustellen ist optional vor den Formschultern eine einklappbare Platte mit einem Einschieber vorgesehen. Die einklappbare Platte mit einem dahinter liegenden Abschieber sorgt, bevor die nƤchste Gruppe beziehungsweise Formation eingeschoben wird, dafĆ¼r, dass zwischen den beiden Formationen der notwendige Abstand entsteht, um die QuerschweiƟung durchfĆ¼hren zu kƶnnen. Hierdurch ist erreicht, dass beispielsweise das letzte rollenfƶrmige Verbrauchs- beziehungsweise Tissueprodukt einer Gruppe beziehungsweise Formation, das sich in der Formschulter befindet, nicht rĆ¼ckwƤrts herausrausfƤllt oder zu lose von dem Folienschlauch umhĆ¼llt wird.Such drivers can usually drive only to the front edge of the forming shoulders. In order to produce a necessary gap between groups of consumer products or tissue products, a retractable plate with a slide is optionally provided in front of the forming shoulders. The retractable plate with a behind the pusher ensures, before the next group or formation is inserted, that between the two formations of the necessary distance arises in order to perform the transverse welding can. This ensures that, for example, the last roll-shaped consumable or tissue product of a group or formation that is located in the forming shoulder does not fall out backwards or is wrapped too loosely by the film tube.

Das kontinuierliche ZufĆ¼hren einer Folienbahn von beispielsweise einer groƟen Vorratsrolle erweist sich zudem als deutlich weniger aufwƤndig als das Vorhalten von jeweiligen Stapeln mit vorgefertigten Verpackungsbeuteln.The continuous feeding of a film web of, for example, a large supply roll also proves to be much less expensive than the provision of respective stacks with prefabricated packaging bags.

Auf diese Weise ist es in vorteilhafter Weise eine Verpackung von Verbrauchs- beziehungsweise Tissueprodukten ermƶglicht, welche mit besonders wenig Aufwand und besonders wenig Materialverwurf an Folie verbunden ist.In this way, it is advantageously possible to package consumer products or tissue products, which is connected to film with particularly little effort and particularly little material throwing.

Entsprechend einer bevorzugten Ausgestaltungsvariante der erfindungsgemƤƟen Folienschlauchverpackungsmaschine sind die beiden Formschultern derart ausgestaltet, dass der Falzebenenbereich genau drei Folienlagen aufweist, wobei eine jeweilige Folienlage aus zwei nicht Ć¼berlappenden seitlichen Kantenbereichen zweier Folienbahnen gebildet ist, welche an ihren Kanten aneinander stoƟen. Hierdurch ist ein fĆ¼r viele AnwendungsfƤlle geltendes Optimum zwischen hinreichender StabilitƤt des Tragegriffs und Materialersparnis erreicht.According to a preferred embodiment variant of the film tube packaging machine according to the invention, the two forming shoulders are configured such that the folded plane region has exactly three film layers, wherein a respective film layer is formed from two non-overlapping lateral edge regions of two film webs which abut one another at their edges. As a result, a valid for many applications optimum between sufficient stability of the handle and material savings is achieved.

GemƤƟ einer weiteren erfindungsgemƤƟen Ausgestaltung der Folienschlauchverpackungsmaschine weisen die zwei Fƶrdervorrichtungen mehrere im Bereich der jeweiligen portalƤhnlichen Formschulter hintereinander geschaltete Teilfƶrdervorrichtungen auf, wobei in Fƶrderrichtung hinter der jeweiligen Formschulter zwei jeweils synchron laufende bandƤhnliche Teilfƶrdervorrichtungen unterhalb und oberhalb des jeweiligen tunnelƤhnlichen Folienschlauches vorgesehen sind. Auf diese Weise ist eine kontinuierliche Bewegung der jeweiligen FolienschlƤuche erreicht, wobei die jeweilige Gruppe von zu verpackenden Verbrauchs- beziehungsweise Tissueprodukten zwischen den Teilfƶrdervorrichtungen eingeklemmt ist und von diesen zusammen mit dem Folienschlauch mitgenommen wird. Die synchron laufenden Teilfƶrdervorrichtungen kƶnnen beispielsweise als Riemen ausgefĆ¼hrt sein, welche durch ihre Anordnung oben und unten auch als Pressriemen zu verstehen sind.According to a further inventive embodiment of the film tube packaging machine, the two conveying devices have a plurality of in the region of the respective portal-like form shoulder successively connected part conveyors, wherein in the conveying direction behind the respective form shoulder two respectively synchronously running band-like part conveyors are provided below and above the respective tunnel-like film tube. In this way, a continuous movement of the respective film tubes is achieved, wherein the respective group of consumable or tissue products to be packaged is clamped between the partial conveying devices and taken along by these together with the film tube. The synchronously running part conveyors For example, they can be designed as belts which, by virtue of their arrangement at the top and bottom, are also to be understood as compression belts.

Entsprechend einer weiteren Variante der Folienschlauchverpackungsmaschine weisen die jeweils in Fƶrderrichtung vor der Formschulter befindlichen Teilfƶrdervorrichtungen ein Band, insbesondere ein jeweiliges Fƶrderband mit einem jeweiligen Antriebsschieber auf. Diese ist derart ausgestaltet, dass auf dem Fƶrderband befindliche Verbrauchs- beziehungsweise Tissueprodukte mit dem Antriebsschieber durch die Formschulter geschoben und dort den jeweils synchron laufenden bandƤhnlichen Teilfƶrdervorrichtungen zum weiteren Transport Ć¼bergeben werden. Eine Fƶrdervorrichtung kann eine oder auch jeweils mehrere Spuren fĆ¼r Reihen von beispielsweise rollenfƶrmigen oder auch gestapelten Verbrauchs- beziehungsweise Tissueprodukten aufweisen.According to a further variant of the film tube packaging machine, the partial conveying devices respectively located in the conveying direction in front of the forming shoulder have a band, in particular a respective conveyor belt with a respective drive slider. This is designed such that located on the conveyor consumable or tissue products are pushed with the drive slide through the forming shoulder and there passed the respective synchronously running band-like part conveyors for further transport. A conveyor device may have one or even a plurality of tracks for rows of, for example, roll-shaped or else stacked consumable or tissue products.

Ein Antriebsschieber kann dafĆ¼r vorgesehen sein, Gruppen beziehungsweise Formationen von zu verpackenden Verbrauchs- beziehungsweise Tissueprodukten mit einem Abstand zwischen den Gruppen in Richtung von nachfolgenden QuerverschweiƟungsmitteln zu schieben. Im Falle von Rollenmaterial kann dieser Abstand beispielsweise etwa einen Rollendurchmesser betragen. Ein derart erzeugter Abstand ist Voraussetzung fĆ¼r eine nachfolgende QuerverschweiƟung der jeweiligen Folienbeutel.A drive slide can be provided for pushing groups or formations of consumable or tissue products to be packaged with a distance between the groups in the direction of subsequent transverse welding means. In the case of roll material, this distance may be, for example, about a roll diameter. Such a generated distance is a prerequisite for a subsequent transverse welding of the respective foil bag.

GemƤƟ einer weiteren Ausgestaltungsvariante der erfindungsgemƤƟen Folienschlauchverpackungsmaschine weist diese in Fƶrderrichtung hinter den Formschultern fĆ¼r die mechanische AbstĆ¼tzung des Falzebenenbereiches eine synchron zu den bandƤhnlichen Teilfƶrdervorrichtungen bewegbare bandƤhnliche StĆ¼tzvorrichtung auf etwa halber vertikaler Hƶhe der jeweiligen Gruppe von zu verpackenden Verbrauchsbeziehungsweise Tissueprodukten auf, beispielsweise ein oder mehrere mitlaufende BƤnder, welche zumindest im Bereich einer LƤngsschweiƟvorrichtung vorzugsweise aus Teflon gefertigt sind beziehungsweise damit beschichtet sind. Somit ist gewƤhrleistet, dass sich der Falzebenenbereich und damit auch der Tragegriff der Verpackung, welcher in der fertigen Verpackung vorzugsweise ein eingestanztes Trageloch aufweist, etwa mittig befindet, so dass die Verpackung mit der darin befindlichen Rollenware einfach lotsenkrecht getragen werden kann. Eine Stanzvorrichtung fĆ¼r ein Trageloch ist typischerweise in einem nachfolgenden Segment der erfindungsgemƤƟen Folienschlauchverpackungsmaschine vorgesehen.According to a further embodiment variant of the film tube packaging machine according to the invention this has in the conveying direction behind the forming shoulders for the mechanical support of the folding plane area a synchronous to the band-like Teilfƶrdervorrichtungen movable tape-like support device to about half vertical height of the respective group of consumable or Tissueprodukten to be packaged, for example, one or more moving bands which are preferably made of Teflon or at least coated in the region of a longitudinal welding device. Thus, it is ensured that the folded plane region and thus also the carrying handle of the packaging, which preferably has a punched-in carrying hole in the finished packaging, is located approximately in the middle, so that the packaging with the roll goods located therein can easily be carried straightly. A punching device for A carrying hole is typically provided in a subsequent segment of the film tube packaging machine according to the invention.

Entsprechend einer weiteren Erfindungsvariante weist die Folienschlauchverpackungsmaschine Mittel auf, um die Folienlagen im Falzebenenbereich miteinander zu vernadeln. Dies erfolgt beispielsweise mittels einer Nadelwalze mit Gegenrolle. Hierdurch kann der Falzebenenbereich bereits vor seiner VerschweiƟung formstabil verbunden werden, womit die weitere Verarbeitung in vorteilhafter Weise vereinfacht ist.According to a further variant of the invention, the film tube packaging machine has means for needling together the film layers in the folded plane region. This is done for example by means of a needle roller with counter-roller. As a result, the folded plane region can be connected in a dimensionally stable manner even before it is welded, thus simplifying further processing in an advantageous manner.

GemƤƟ einer weiteren Variante der Folienschlauchverpackungsmaschine weist diese Mittel wie eine LƤngsschweiƟvorrichtung auf, um die Folienlagen im Falzebenenbereich miteinander zu verschweiƟen, sowie eine LƤngsschneidevorrichtung zum Schneiden des verschweiƟten Falzebenenbereiches. Eine VerschweiƟung erfolgt beispielsweise mittels einer oder mehrerer HeiƟluftdĆ¼sen, es sind aber auch durchaus eine Vielzahl weiterer Alternativen denkbar. Das Trennen beziehungsweise das Versiegeln der im Falzebenenbereich befindlichen Folienenden erfolgt beispielsweise mittels eines sogenannten "Slit Sealers". Somit ist es mƶglich, den Schlauchbeutel mit der darin befindlichen Gruppe von Verbrauchs- beziehungsweise Tissueprodukten seitlich zu verschlieƟen sowie eine Auftrennung von parallel durch den Falzebenenbereich verbundenen Schlauchbeuteln durchzufĆ¼hren.According to a further variant of the film tube packaging machine, this means comprises a longitudinal welding device in order to weld the film layers together in the folded plane region, as well as a longitudinal cutting device for cutting the welded folded plane region. A welding is done for example by means of one or more hot air nozzles, but there are quite a variety of other alternatives conceivable. The separation or sealing of the film ends located in the folded plane area is effected for example by means of a so-called "slit sealer". Thus, it is possible to laterally close the tubular bag with the group of consumable or tissue products contained therein as well as to carry out a separation of tubular bags connected in parallel through the folded flat area.

GemƤƟ einer weiteren erfindungsgemƤƟen Ausgestaltungsvariante der Folienschlauchverpackungsmaschine weist diese Mittel auf, um eine QuerverschweiƟung der lƤngs einer gemeinsamen Ebene verlaufenden parallelen tunnelƤhnlichen FolienschlƤuchen durchzufĆ¼hren und diese so zu verschlieƟen wobei diese auch eine Querschneidevorrichtung aufweist.According to a further embodiment variant of the film tubular packaging machine according to the invention, this means has to carry out a transverse welding of the parallel tunnel-like film tubes running along a common plane and thus to close them, which also has a transverse cutting device.

Die Mittel zur QuerverschweiƟung und die Querschneidevorrichtung sind in einer weiteren Ausgestaltungsvariante lƤngs der Fƶrderrichtung verstellbar, so dass der Abstand zwischen Vorderkante der Formschultern und QuerverschweiƟung, durch welchen die LƤnge der Verpackung bestimmt ist, anpassbar ist. Ebenso ist es erfindungsgemƤƟ mƶglich, die Teilfƶrdervorrichtungen beziehungsweise die FƶrderbƤnder, zwischen denen die Gruppen von zu verpackenden Verbrauchs- beziehungsweise Tissueprodukten temporƤr eingeklemmt sind, zwei- oder mehrgliedrig nach oben beziehungsweise unten klappbar zu machen. Somit kann durch Klappen eines Gliedes oder Segmentes eines jeweiligen Fƶrderbandes Platz geschaffen werden, um einen Querbalken mit QuerschweiƟvorrichtung und Schneidevorrichtung dort hineinzubewegen. Somit kann die VerpackungslƤnge der erfindungsgemƤƟen Folienschlauchverpackungsmaschine bedarfsweise verkĆ¼rzt beziehungsweise angepasst werden.The means for transverse welding and the cross-cutting device are adjustable in a further embodiment variant along the conveying direction, so that the distance between the front edge of the forming shoulders and transverse welding, through which the length of the package is determined, is adaptable. Likewise, it is possible according to the invention, the sub-conveying devices or the conveyor belts, between which the groups of consumable or tissue products to be packaged are temporarily clamped, two or more members after to make hinged up or down. Thus, by folding a member or segment of a respective conveyor belt space can be created to move a cross bar with cross-welding device and cutting device in there. Thus, the packaging length of the film tube packaging machine according to the invention can be shortened or adjusted as needed.

Bei der QuerverschweiƟung werden vorzugsweise zwei parallele SchweiƟnƤhte gleichzeitig produziert, eine fĆ¼r die beiden nach hinten ablaufenden Packungen und die andere fĆ¼r die noch zwischen den PressbƤndern befindliche Beutelformation. Eine Querschneidevorrichtung trennt die beiden Beutelformationen zwischen den QuerschweiƟnƤhten, beispielsweise ein gezahntes Messer, welches pneumatisch angetrieben wird. Somit ist es mƶglich, den Schlauchbeutel mit der darin befindlichen Rollenware an seinen Enden quer zu verschlieƟen sowie eine Trennung von hintereinander befindlichen Schlauchbeuteln beziehungsweise Schlaubeutelformationen durchzufĆ¼hren. Es kann sich als vorteilhaft erweisen, den axialen Vorschub der Fƶrdervorrichtungen wƤhrend der QuerschweiƟung und/oder der Quertrennung anzuhalten.In transverse welding, preferably two parallel welds are produced simultaneously, one for the two backward packs and the other for the bag formation still in between the press belts. A cross cutter separates the two bag formations between the transverse welds, for example a serrated knife which is pneumatically driven. Thus, it is possible to close the tubular bag with the roll goods therein transversely at its ends and to carry out a separation of successive tubular bags or Schlaubeutelformationen. It may prove advantageous to stop the axial feed of the conveyors during the transverse welding and / or the transverse separation.

Nach der Quertrennung der Beutelformationen wird mittels einer Stanzvorrichtung ein jeweiliges Trageloch eingestanzt, so dass aus dem jeweiligen Ɯberstand ein Tragegriff gebildet ist. Hierzu ist es zweckmƤƟig, dass die jeweiligen Verpackungsbeutel zuvor von einer Antriebseinheit mit AnpressbƤndern Ć¼bernommen werden, um eine sichere Positionierung beim Stanzen zu gewƤhrleisten.After the transverse separation of the bag formations, a respective carrying hole is punched by means of a punching device, so that a carrying handle is formed from the respective projection. For this purpose, it is expedient that the respective packaging bags are previously taken over by a drive unit with pressure belts in order to ensure a secure positioning during punching.

GemƤƟ einer weiteren Ausgestaltungsvariante der Folienschlauchverpackungsmaschine weisen die beiden Fƶrdervorrichtungen unabhƤngig voneinander eine, zwei oder drei Fƶrderspuren fĆ¼r je eine Reihe von beispielsweise rollenfƶrmigen, gestapelten oder gefalteten Verbrauchs- beziehungsweise Tissueprodukten auf. Somit ist es mƶglich, auch verschiedene VerpackungsgrĆ¶ĆŸen mit derselben Folienschlauchverpackungsmaschine herzustellen, wobei in jedem Fall der gemeinsame Falzebenenbereich zwischen den axial gleich langen Verpackungen genutzt wird, um einen Tragegriff daraus zu fertigen.According to a further embodiment variant of the tubular film packaging machine, the two conveying devices independently of one another have one, two or three conveying tracks for each row of, for example, roll-shaped, stacked or folded consumable or tissue products. Thus, it is possible to produce also different packaging sizes with the same film tube packaging machine, in each case the common folded plane area between the axially equal length packages is used to manufacture a carrying handle therefrom.

Entsprechend einer weiteren Ausgestaltungsform der erfindungsgemƤƟen Folienschlauchverpackungsmaschine ist diese auch dafĆ¼r vorgesehen, Gruppen von rollenfƶrmigen Verbrauchs- beziehungsweise Tissueprodukten mit einer jeweiligen Rotationsachsenausrichtung quer zur Fƶrderrichtung zu verpacken. Dies hat den Vorteil, dass durch die Ausrichtung der Verbrauchs- beziehungsweise Tissueprodukte im oberen und unteren Bereich an den axialen Enden quer zur Fƶrderrichtung abgerundete Bereiche gebildet sind, welche ein EinfĆ¼hren der gruppierten rollenfƶrmigen Verbrauchs- beziehungsweise Tissueprodukte durch die jeweilige Formschulter erleichtern, ebenso wie das EinfĆ¼hren der Rollen in den dahinter befindlichen Folienschlauch. Auch ein QuerverschweiƟen der Folienbeutel wird dadurch in vorteilhafter Weise erleichtert.According to a further embodiment of the film tubular packaging machine according to the invention, this is also intended to pack groups of roll-shaped consumable or tissue products with a respective axis of rotation alignment transverse to the conveying direction. This has the advantage that rounded areas are formed by the orientation of the consumable or tissue products in the upper and lower regions at the axial ends transversely to the conveying direction, which facilitate insertion of the grouped roll-shaped consumable or tissue products by the respective forming shoulder, as well as Insert the rollers into the film tube located behind. A transverse welding of the foil bag is thereby facilitated in an advantageous manner.

Es sei an dieser Stelle noch einmal explizit darauf hingewiesen, dass eine erfindungsgemƤƟe Folienschlauchverpackungsmaschine von ihrem Prinzip her selbstverstƤndlich auch grundsƤtzlich dafĆ¼r geeignet ist, stehende rollenfƶrmige Verbrauchs- beziehungsweise Tissueprodukte mit senkrechter Ausrichtung der Rotationsachse oder auch nicht-rollenfƶrmige Verbrauchs- beziehungsweise Tissueprodukte zu verpacken.It should again be explicitly pointed out at this point that a film tubular packaging machine according to the invention is, of course, basically also suitable for packaging standing roll-shaped consumable or tissue products with a vertical alignment of the axis of rotation or else non-roll-shaped consumable or tissue products.

GemƤƟ einer weiteren Variante der Folienschlauchverpackungsmaschine weist diese eine Drehvorrichtung auf, um rollenfƶrmige Verbrauchs- beziehungsweise Tissueprodukte mit einer Rotationsachsenausrichtung beispielsweise lƤngs der Fƶrderrichtung oder auch stehend jeweils quer zur Fƶrderrichtung zu drehen. Somit kƶnnen beispielsweise Verbrauchs- beziehungsweise Tissueprodukte, welche aufgrund produktionstechnischer Bedingungen mit einer Rotationsachsenausrichtung lƤngs der Fƶrderrichtung quer dazu gedreht werden. Eine derartige Vorrichtung umfasst vorteilhafter Weise einen drehbaren Greifer mit einem Ɩffnungsbereich von etwas mehr als dem Durchmesser des jeweiligen rollenfƶrmigen Verbrauchs- beziehungsweise Tissueproduktes.According to a further variant of the film tubular packaging machine, this has a rotating device to rotate roll-shaped consumable or tissue products with a rotational axis alignment, for example, along the conveying direction or also standing transversely to the conveying direction. Thus, for example, consumable or tissue products, which are rotated due to production conditions with a rotational axis alignment along the conveying direction transverse thereto. Such a device advantageously comprises a rotatable gripper having an opening area of slightly more than the diameter of the respective roll-shaped consumable or tissue product.

GemƤƟ einer weiteren Ausgestaltungsvariante der Folienschlauchverpackungsmaschine weist diese eine Separiervorrichtung auf, um ein beispielsweise bereits vorkonfektioniertes Ausgangsmaterial, insbesondere geschnittene Rollen, zu separieren. Die Separiervorrichtung umfasst beispielsweise sternfƶrmig angeordnete Separierkanten oder Zacken, welche um eine gemeinsame Drehachse quer zur Fƶrderrichtung rotieren. Die geschnittenen Rollen laufen beispielsweise von einer SƤge kommend vierspurig zur Separiervorrichtung und sind hierbei dicht auf dicht in einer stammƤhnlichen Formation angeordnet, welche mehrere Meter lang sein kann. Nach deren Separation werden die Rollen dann dem weiteren Verpackungsvorgang zugefĆ¼hrt. FĆ¼r lƤngere Rollen wie beispielsweise KĆ¼chenpapierrollen sind auch andere Arten von Separiervorrichtungen denkbar beziehungsweise notwendig.According to a further embodiment variant of the film tube packaging machine, the latter has a separating device in order to separate a starting material, in particular cut rolls, for example, which has already been prefabricated. The separating device comprises, for example, star-shaped separating edges or spikes, which rotate about a common axis of rotation transversely to the conveying direction. The cut rolls run, for example coming from a saw four-lane to the separating and are here arranged close to tight in a trunk-like formation, which can be several meters long. After separation, the rolls are then fed to the further packaging process. For longer rolls such as paper towels, other types of separating devices are conceivable or necessary.

GemƤƟ einer weiteren Ausgestaltungsvariante der erfindungsgemƤƟen Folienschlauchverpackungsmaschine sind die zwei Fƶrdervorrichtungen im Wesentlichen spiegelsymmetrisch aufgebaut. Idealerweise sind alle lƤngs der Fƶrderrichtung angeordneten Komponenten beider Fƶrdervorrichtungen auf gleicher axialer Hƶhe, beispielsweise ein gemeinsamer Querbalken mit SchweiƟ- beziehungsweise Schneidevorrichtung oder auch die beiden Formschultern.According to a further embodiment variant of the film tube packaging machine according to the invention, the two conveying devices are constructed essentially mirror-symmetrically. Ideally, all components of both conveying devices arranged along the conveying direction are at the same axial height, for example a common transverse bar with welding or cutting device or else the two forming shoulders.

Die erfindungsgemƤƟe Aufgabe wird auch gelƶst durch ein Verfahren zum Verpacken von Verbrauchsprodukten, insbesondere Tissueprodukten, mit einer Folienschlauchverpackungsmaschine, umfassend

  • zwei Fƶrdervorrichtungen mit zwei diesen jeweils zugeordneten portalƤhnlichen Formschultern, welche jeweils dafĆ¼r vorgesehen sind, eine diesen jeweils zugefĆ¼hrte Folienbahn derart in Fƶrderrichtung der jeweiligen Fƶrdervorrichtung umzulenken, dass in Fƶrderrichtung hinter den Formschultern ein jeweiliger tunnelƤhnlicher Folienschlauch als Verpackung geformt wird,
  • wobei die zwei Fƶrdervorrichtungen dafĆ¼r vorgesehen sind, Gruppen von auf diesen befindlichen zu verpackenden Verbrauchsprodukten mit einer vorgegebenen Vorschubgeschwindigkeit durch die jeweilige Formschulter in den jeweiligen tunnelƤhnlichen Folienschlauch zu bewegen, wobei sich dieser dabei mit derselben Vorschubgeschwindigkeit bewegt wie die Verbrauchsprodukte,

Figur 1 zeigt eine exemplarische erste Folienschlauchverpackungsmaschine 10 in einer schematischen Draufsicht. Zwei portalƤhnliche Formschultern 24, 26 sind jeweils zwei Fƶrderbandeinrichtungen 12, 14 zugeordnet, welche parallel lƤngs einer gemeinsamen Ebene befindlich sind. Auf jeder der Fƶrdervorrichtungen 12, 14 sind in Fƶrderrichtung 20, 22 vor den Formschultern 24, 26 jeweils Gruppen 16, 18 von zu verpackendem Tissueprodukte befindlich, in diesem Fall Gruppen von je 2 x 5 Rollen. Beide Fƶrderbandeinrichtungen 12, 14 sind fĆ¼r jeweils eine Breite von zwei respektive drei Reihen Tissueprodukte geeignet. FIG. 1 shows an exemplary first film tube packaging machine 10 in a schematic plan view. Two portal-like forming shoulders 24, 26 are each associated with two conveyor belt devices 12, 14, which are located parallel along a common plane. On each of the conveying devices 12, 14 are in the conveying direction 20, 22 in front of the forming shoulders 24, 26 each groups 16, 18 of tissue products to be packaged, in this case groups of 2 x 5 roles. Both conveyor belt devices 12, 14 are suitable for in each case a width of two or three rows of tissue products.

Die Fƶrdervorrichtungen 12, 14 sind dafĆ¼r vorgesehen, die Gruppen 16, 18 von auf diesen befindlichen Tissueprodukten durch die Formschultern 24, 26 in einen jeweiligen tunnelƤhnlichen Folienschlauch 40, 42 zu bewegen, welcher die Basis fĆ¼r die Verpackung bildet. Die beiden Formschultern 24, 26 sind derart ausgestaltet, dass durch diese eine jeweils seitlich zugefĆ¼hrte Folienbahn 28, 30 derart umgeformt wird, dass in Fƶrderrichtung 20, 22 hinter den Formschultern 24, 26 die zwei tunnelƤhnlichen FolienschlƤuche 40, 42 gebildet sind.The conveyors 12, 14 are intended to move the groups 16, 18 of tissue products thereon through the forming shoulders 24, 26 into a respective tunnel-like film tube 40, 42 which forms the base for the package. The two forming shoulders 24, 26 are configured in such a way that they respectively transform a laterally supplied film web 28, 30 such that the two tunnel-like film tubes 40, 42 are formed in the conveying direction 20, 22 behind the forming shoulders 24, 26.

Mit den Bezugsziffern 32, 34 sind jeweilige Gruppen von Tissueprodukten gekennzeichnet, welche sich bereits jeweils in den als Verpackungsbasis dienenden tunnelƤhnlichen FolienschlƤuchen 40, 42 befinden und welche an ihrem in der Figur rechten axialen Ende bereits mit einer durchgehenden QuerschweiƟnaht verschlossen sind. In einem zwischen den tunnelƤhnlichen FolienschlƤuchen 40, 42 befindlichen Falzebenenbereich 36, 38, dessen Breite im Wesentlichen von dem Abstand 48 der Fƶrdervorrichtungen zueinander bestimmt wird, sind die seitlichen Kantenbereiche der zu tunnelƤhnlichen FolienschlƤuchen 40, 42 geformten Folienbahnen 28, 30 in mehreren Folienlagen Ć¼berlappend angeordnet.The reference numerals 32, 34 are respective groups of tissue products characterized, which are already each in the serving as a packaging base tunnel-like film tubes 40, 42 and which are closed at its right in the figure axial end already with a continuous transverse weld. In a folded plane region 36, 38 located between the tunnel-like film tubes 40, 42, the width of which is essentially determined by the distance 48 between the conveying devices, the lateral edge regions of the film webs 28, 30 formed into tunnel-like film tubes 40, 42 are overlapped in several film layers ,

Der Falzebenenbereich 36, 38 ist dafĆ¼r vorgesehen, verschweiƟt zu werden, so dass damit ein seitlicher Verschluss der FolienschlƤuchen 40, 42 gewƤhrleistet ist. Der Falzebenenbereich 36, 38 umfasst in diesem Fall drei Folienlagen, wobei in einer Folienlage aneinander grenzend zwei der insgesamt vier seitlichen Kantenbereiche der zwei Folienlagen vorgesehen sind. Durch die verschweiƟte dreifache Folienlage ist eine gute mechanische Belastbarkeit des Falzebenenbereiches 36, 38 gegeben, so dass dieser nachfolgend zerteilt werden kann, um daraus durch Hereinstanzen eines Tragelochs jeweils Tragegriffe fĆ¼r die verpackte Gruppe von Tissueprodukten zu bilden. Eine entsprechende Stanzvorrichtung ist typischerweise in einem weiteren nachgeordneten Segment der Folienschlauchverpackungsmaschine vorgesehen.The folded plane region 36, 38 is intended to be welded, so that a lateral closure of the film tubes 40, 42 is ensured. The folded plane region 36, 38 in this case comprises three film layers, wherein in a film layer adjacent to each other two of the four lateral edge regions the two film layers are provided. The welded triple layer of film gives good mechanical strength of the folded plane region 36, 38, so that it can be subsequently cut to form carrier handles for the packaged group of tissue products by punching in a carrying hole. A corresponding punching device is typically provided in a further downstream segment of the film tube packaging machine.

Figur 2 zeigt eine erste Anordnung von FolienschlƤuchen mit Falzebenenbereich mit drei Folienlagen in einer Skizze 50 als Querschnittsansicht. Zwei Reihen von zu verpackenden Tissueprodukten 52, 54 sind parallel zueinander auf einer jeweils nicht gezeigten Fƶrdervorrichtung angeordnet. Jede Reihe zu verpackender Tissueprodukte 52, 54 ist von einem jeweiligen tunnelƤhnlichen Folienschlauch 56, 58 umhĆ¼llt, welcher seinerseits aus einer entsprechend umgeformten Folienbahn gebildet ist. Die seitlichen Kantenbereiche der Folienbahnen mĆ¼nden in einen zwischen den tunnelƤhnlichen FolienschlƤuchen 56, 58 befindlichem Falzebenenbereich 60. FIG. 2 shows a first arrangement of film hoses with folded layer area with three film layers in a sketch 50 as a cross-sectional view. Two rows of tissue products 52, 54 to be packaged are arranged parallel to one another on a conveying device, not shown in each case. Each row of tissue products 52, 54 to be wrapped is enveloped by a respective tunnel-like film tube 56, 58, which in turn is formed from a correspondingly formed film web. The lateral edge regions of the foil webs open into a fold plane region 60 located between the tunnel-like foil tubes 56, 58.

Die beiden Folienbahnen weisen jeweils zwei seitliche Kantenbereiche auf, so dass insgesamt vier seitliche Kantenbereiche in den Falzebenenbereich 60 mĆ¼nden. In diesem Beispiel sind insgesamt drei komplette Folienlagen vorhanden, wobei in der mittleren Folienlage zwei aneinanderstoƟende seitliche Kantenbereiche vorgesehen sind.The two film webs each have two lateral edge regions, so that a total of four lateral edge regions open into the folded plane region 60. In this example, a total of three complete film layers are present, wherein two abutting lateral edge regions are provided in the middle film layer.

Der seitliche Versatz zwischen den Katenbereichen der Folienbahnen quer zur Fƶrderrichtung kann beispielsweise 60mm betragen, wobei die Breite des Falzebenenbereiches derart zu bemessen ist, dass daraus zwei nebeneinander befindliche Tragegriffe geschnitten werden kƶnnen, also beispielsweise zwischen 100mm und 140mm. Durch VerschweiƟen des Falzebenenbereiches 60 wird ein derart stabiler FolienĆ¼berstand gebildet, dass dieser nach Teilung lƤngs der Fƶrderrichtung und nach Einstanzen eines Tragelochs als Tragegriff fĆ¼r die verpackten Tissueprodukte nutzbar ist.The lateral offset between the Katenbereiche the film webs transverse to the conveying direction may be, for example, 60mm, the width of the Falzebenenbereiches is to be dimensioned such that it can be cut two side by side carrying handles, so for example between 100mm and 140mm. By welding the folded plane region 60, a film projection which is stable in this way is formed so that it can be used as a carrying handle for the packaged tissue products after being divided along the conveying direction and after punching in a carrying hole.

Figur 3 zeigt eine erste Anordnung von FolienschlƤuchen mit Falzebenenbereich mit vier Folienlagen in einer Skizze 70 als Querschnittsansicht. Zwei Reihen von zu verpackenden Tissueprodukten 72, 74 sind parallel zueinander auf einer jeweils nicht gezeigten Fƶrdervorrichtung angeordnet. Jede Reihe zu verpackender Tissueprodukte ist von einem jeweiligen tunnelƤhnlichen Folienschlauch 76, 78 umhĆ¼llt, welcher seinerseits aus einer entsprechend umgeformten Folienbahn gebildet ist. Die seitlichen Kantenbereiche der Folienbahnen mĆ¼nden in einen zwischen den tunnelƤhnlichen FotienschlƤuchen 76, 78 befindlichem Falzebenenbereich 80. In diesem Beispiel sind insgesamt vier komplette Folienlagen im Falzebenenbereich 80 vorhanden, wodurch die StabilitƤt eines daraus gebildeten Tragegriffs weiter erhƶht ist. FIG. 3 shows a first arrangement of film hoses with folded layer area with four film layers in a sketch 70 as a cross-sectional view. Two rows of tissue products 72, 74 to be packaged are not parallel to each other arranged conveyor. Each row of tissue products to be packaged is enveloped by a respective tunnel-like film tube 76, 78, which in turn is formed from a correspondingly formed film web. The lateral edge regions of the film webs open into a folding plane region 80 located between the tunnel-like photographic tubes 76, 78. In this example, a total of four complete film layers are present in the folded plane region 80, whereby the stability of a carrying handle formed therefrom is further increased.

Figur 4 zeigt in einer Skizze 90 eine erfindungsgemƤƟ hergestellte Folienverpackung 94 mit einer Gruppe von darin verpackten Tissueprodukten 96, in diesem Fall Packungen von Tissue- oder Papierprodukten. Der oben im Bild dargestellte Ɯberstand war wƤhrend des Verpackungsvorhangs Teil 92 eines Falzebenenbereiches. In den Ɯberstand ist ein Trageloch 98 eingestanzt. FIG. 4 shows in a sketch 90 a film package 94 produced according to the invention with a group of tissue products 96 packed therein, in this case packages of tissue or paper products. The supernatant shown in the picture above was part 92 of a folded plane area during the packaging curtain. In the supernatant a carrying hole 98 is stamped.

Figur 5 zeigt eine exemplarische zweite Folienschlauchverpackungsmaschine 100 in einer schematischen Draufsicht. Zwischen Gruppen von bereits verpackten Tissueprodukten ist ein Falzebenenbereich 102 gebildet. Eine nicht gezeigte Nadelvorrichtung ist dafĆ¼r vorgesehen, den Falzebenenbereich vor seiner VerschweiƟung durch eine nicht gezeigte SchweiƟvorrichtung zu nadeln, um diesen mƶglichst frĆ¼hzeitig mechanisch zu stabilisieren. FIG. 5 shows an exemplary second film tube packaging machine 100 in a schematic plan view. Between groups of already packaged tissue products, a fold level region 102 is formed. A needle device, not shown, is intended to needling the folded plane area prior to its welding by a welding device, not shown, in order to stabilize this mechanically as early as possible.

Figur 6 zeigt eine exemplarische dritte Folienschlauchverpackungsmaschine 110 in einer dreidimensionalen Ansicht. Auf zwei in der linken BildhƤlfte dargestellten Teilfƶrdervorrichtungen mit Mitnehmer, in diesem Fall zwei zweispurige FƶrderbƤnder mit einem Schieberantrieb, befinden sich zu verpackende Tissueprodukte 118. Diese werden gruppenweise mit einer durch den Schieber bestimmten Vorschubsgeschwindigkeit durch eine jeweilige Formschulter 112 bewegt. Der Formschulter 112 ihrerseits wird seitlich Ć¼ber ein jeweiliges entsprechendes Leitblech eine jeweilige Folienbahn 114 zugefĆ¼hrt, welche beispielsweise von einer grĆ¶ĆŸeren Vorratsrolle abgewickelt wird. FIG. 6 shows an exemplary third film tube packaging machine 110 in a three-dimensional view. Tissue products 118 to be packaged are located on two partial conveying devices with entraining elements shown in the left-hand half, in this case two two-track conveyor belts with a slide drive. These are moved in groups at a feed rate determined by the slide through a respective forming shoulder 112. The forming shoulder 112 in turn is laterally fed via a respective corresponding baffle a respective film web 114, which is unwound, for example, from a larger supply roll.

Durch die jeweilige Formschulter wird die Folienbahn 114 derart umgeformt und umgelenkt, dass zwei jeweilige tunnelƤhnliche FolienschlƤuche als Basis fĆ¼r die Verpackung der Gruppen von Tissueprodukten 118 gebildet sind. Oberhalb und unterhalb der tunnelƤhnlichen FolienschlƤuche sind mehrere bandƤhnliche Teilfƶrdervorrichtung 120 als Bestandteil der jeweiligen Fƶrdervorrichtungen vorgesehen. Diese laufen mit einer Vorschubsgeschwindigkeit, welche auch der Vorschubsgeschwindigkeit des Schiebers entspricht, durch welchen die Tissueprodukte durch die Formschultern 112 bewegt werden.The film web 114 is reshaped and deflected by the respective forming shoulder in such a way that two respective tunnel-like film tubes are formed as the basis for the packaging of the groups of tissue products 118. Above and below The tunnel-like film tubes are provided a plurality of belt-like part conveying device 120 as part of the respective conveying devices. These run at a feed rate, which also corresponds to the feed rate of the slider, through which the tissue products are moved through the forming shoulders 112.

Ein QuerschweiƟbalken 116 erstreckt sich quer zur Fƶrderrichtung Ć¼ber beide Fƶrdervorrichtungen beziehungsweise die betreffenden FolienschlƤuche. Der QuerschweiƟbalken 116 weist in diesem Falle Mittel fĆ¼r eine QuerverschweiƟung der tunnelƤhnlichen FolienschlƤuche auf, so dass diese damit an ihren Enden verschlossen werden kƶnnen. Eine ebenfalls im QuerschweiƟbalken 116 vorgesehene Querschneidevorrichtung ist dafĆ¼r vorgesehen, die quer verschweiƟten Packungen voneinander zu trennen.A transverse welding bar 116 extends transversely to the conveying direction via both conveying devices or the respective film tubes. In this case, the transverse welding bar 116 has means for transverse welding of the tunnel-like foil tubes, so that they can thus be closed at their ends. A transverse cutting device, also provided in the transverse welding bar 116, is provided for separating the transversely welded packings from one another.

Es ist in der Zeichnung gut zu sehen, dass die bandƤhnlichen Teilfƶrdervorrichtungen 120 aus jeweils zwei hintereinander geschalteten FƶrderbƤndern bestehen, wobei das jeweils hintere Fƶrderband nach oben beziehungsweise unten klappbar ist. In geklappten Zustand ist es mƶglich, den in Fƶrderrichtung verstellbaren QuerschweiƟbalken 116 nƤher in Richtung der Formschultern 112 zu verstellen. Dadurch kƶnnen verschiedene VerpackungslƤngen realisiert werden.It can be clearly seen in the drawing that the band-like partial conveying devices 120 each consist of two conveyor belts connected in series, the respective rear conveyor belt being foldable upwards or downwards. In the folded state, it is possible to adjust the adjustable in the conveying direction transverse welding bar 116 closer towards the forming shoulders 112. As a result, different packaging lengths can be realized.

Figur 7 zeigt eine exemplarische vierte Folienschlauchverpackungsmaschine 130 in einer dreidimensionalen Ansicht. Diese entspricht im Wesentlichen der in der Figur 6 gezeigten Folienschlauchverpackungsmaschine, ist aber aus einer anderen Perspektive gezeigt. FIG. 7 shows an exemplary fourth film tube packaging machine 130 in a three-dimensional view. This corresponds essentially to that in the FIG. 6 shown film tube packaging machine, but is shown from a different perspective.

Gezeigt sind wieder die mehrspurigen FƶrderbƤnder 136 mit Mitnehmer als Bestandteil der jeweiligen Fƶrdervorrichtungen, auf welchen Gruppen von zu verpackenden Tissueprodukten befindlich sind, welche durch jeweilige Formschultern 132 gefƶrdert werden. Den Formschultern 132 wird seitlich eine jeweilige Folienbahn 134 zugefĆ¼hrt, welche durch die Formschultern zu einem jeweiligen tunnelƤhnlichen Schlauch umgeformt wird. Gezeigt sind auch im Bereich hinter den Formschultern 132 obere und untere Teilbandfƶrdervorrichtungen 138, welche die Gruppen von zu verpackenden Tissueprodukten im tunnelƤhnlichen Schlauchbeutel oben und unten abstĆ¼tzen, so dass bis zum abschlieƟenden VerschweiƟen der Schlauchbeutel eine formgebende Stabilisierungshilfe gegeben ist.Shown again are the multi-track conveyor belts 136 with drivers as part of the respective conveying devices on which groups of tissue products to be packaged are located, which are conveyed through respective forming shoulders 132. The form shoulders 132 are laterally fed to a respective film web 134, which is formed by the forming shoulders to a respective tunnel-like tube. Shown also in the area behind the forming shoulders 132 are upper and lower sub-belt conveyors 138 which support the groups of tissue products to be packed in the tunnel-like tubular bag at the top and bottom, so that a shaping stabilization aid is given until the final welding of the tubular bag.

Ein nicht dargestellter Teflonriemen ist auf Hƶhe einer ebenfalls nicht dargestellten LƤngsschweiƟeinrichtung dafĆ¼r vorgesehen, den Falzebenenbereich von unten zu unterstĆ¼tzen. Durch die Verwendung des Materials Teflon ist ein Anhaften von geschweiƟtem Material in vorteilhafter Weise vermieden. Ohne eine derartige UnterstĆ¼tzung der Folienenden kƶnnte sich die Folie unter UmstƤnden verziehen, wenn sie nur mit dem Folienschlauch und dem darin befindlichen Tissueprodukt befƶrdert werden wĆ¼rde.An unillustrated Teflon belt is provided at the level of a longitudinal welding device, also not shown, to support the Falzebenenbereich from below. By the use of the material Teflon adhesion of welded material is advantageously avoided. Without such film end support, the film could possibly warp if conveyed only with the film tube and the tissue product therein.

Figur 8 zeigt eine exemplarische fĆ¼nfte Folienschlauchverpackungsmaschine 150 in einer dreidimensionalen Ansicht. Hier sind neben dem eigentlichen in der rechten BildhƤlfte dargestellten KernstĆ¼ck der Folienschlauchverpackungsmaschine noch weitere Komponenten vorgeschaltet. Auf einem mehrspurigen Fƶrderband sind mehrere Rollen 152 befindlich, deren jeweilige Rotationsachsen produktionstechnisch bedingt parallel zur Fƶrderrichtung verlaufen. FIG. 8 shows an exemplary fifth film tube packaging machine 150 in a three-dimensional view. Here are next to the actual core shown in the right half of the film tube packaging machine still preceded by other components. On a multi-track conveyor belt several rollers 152 are located, the respective axes of rotation run production-related condition parallel to the conveying direction.

FĆ¼r jede Spur von Rollen 152 ist eine Separiervorrichtung 154 mit sternƤhnlich angeordneten Separiermitteln vorgesehen, mittels welcher die geschnittenen Rollen 152 separiert werden, wobei deren Ausrichtung danach entweder aufgerichtet oder lƤngs liegend ist. Nachfolgend werden die separierten Rollen beziehungsweise Tissueprodukte einem Fƶrderer Ć¼bergeben.For each track of rollers 152, there is provided a separating device 154 with star-shaped separating means by means of which the cut rollers 152 are separated, their orientation thereafter being either erect or longitudinal. Subsequently, the separated rolls or tissue products are transferred to a conveyor.

Eine Drehvorrichtung 156 ist dafĆ¼r vorgesehen, das separierte rollenfƶrmige Tissueprodukt mittels einer drehbaren Greifvorrichtung zu drehen, so dass die Rotationsachsenausrichtung des Tissueproduktes nunmehr quer zur Fƶrderrichtung ist. Aufgrund der Ausgestaltung der Drehvorrichtung ist diese jedoch in der Lage, beliebig ausgerichtete Tissueprodukte in die gewĆ¼nschte Ausrichtung quer zur Fƶrderrichtung zu drehen, wobei die Tissueprodukte auch nicht zwangslƤufig rollenfƶrmig sein mĆ¼ssen.A turning device 156 is provided to rotate the separated roll-shaped tissue product by means of a rotatable gripping device so that the rotational axis orientation of the tissue product is now transverse to the conveying direction. Due to the design of the rotating device, however, it is able to rotate arbitrarily oriented tissue products in the desired orientation transversely to the conveying direction, wherein the tissue products need not necessarily be roll-shaped.

Nachfolgend wird das gedrehte Tissueprodukt auf ein mehrspuriges Fƶrderband 160, welche als Teilfƶrdervorrichtung der gesamten Fƶrdervorrichtung anzusehen ist, Ć¼bergeben. Mittels eines Antriebsschiebers 158 werden Gruppen von zu verpackenden Tissueprodukten durch die Formschultern bewegt, wo der eigentliche Verpackungsvorgang erfolgt.Subsequently, the twisted tissue product is applied to a multi-track conveyor 160, which is to be regarded as a partial conveying device of the entire conveyor, to hand over. By means of a drive slide 158, groups of tissue products to be packaged are moved through the forming shoulders where the actual packaging process takes place.

Figur 9 zeigt die Komplettansicht einer exemplarischen sechste Folienschlauchverpackungsmaschine 170 in einer dreidimensionalen Form, umfassend eine Separiervorrichtung fĆ¼r geschnittene Rollen Ausgangsmaterial, eine Drehvorrichtung fĆ¼r separierte rollenfƶrmige Tissueprodukte, eine Fƶrdervorrichtung, Formschultern zur Formung von tunnelƤhnlichen FolienschlƤuchen aus zugefĆ¼hrten Folienbahnen, welche die Ausgangsbasis fĆ¼r die Verpackung der Gruppen von Tissueprodukten bilden. FIG. 9 Fig. 3 shows the complete view of an exemplary sixth film tube packaging machine 170 in a three-dimensional form, including a cut roll separator, a separator for separated roll-shaped tissue products, a conveyor, forming shoulders for forming tunnel-like foil tubes from fed foil webs, which provide the starting point for packaging the groups of Figs Tissue products form.
