Description

Die Erfindung betrifft ein Verfahren zum Verpacken einer Materialbahnrolle, bei dem eine Verpackungsbahn zur Bildung einer Korpusverpackung schraubenlinienförmig um die Materialbahnrolle gewickelt wird, die unter Ausbildung eines axial inneren Endes und eines axial äußeren Endes an einer Trennlinie endet und die Verpackungsbahn am Anfang und/oder am Ende der Materialbahnrolle zur Bildung einer Endverpackung unter Ausbildung eines im wesentlichen gleichförmigen axialen Überstandes in Umfangsrichtung um die Materialbahnrolle gewickelt wird.The invention relates to a method for packaging a Roll of material in which a packaging web for Formation of a body packaging in a helical shape the web of material is wound, which is under training an axially inner end and an axially outer It ends at a dividing line and the packaging line at the beginning and / or at the end of the web of material Formation of a final packaging with the formation of an im substantially uniform axial projection in the circumferential direction is wrapped around the roll of material.

Ein derartiges Verfahren ist aus der nach dem Prioritätstag veröffentlichten EP-A-0 765 809 bekannt.Such a procedure is based on that after the priority date published EP-A-0 765 809.

Verpackungen dieser Art haben den Vorteil, daß man unabhängig von der Breite der zu verpackenden Materialbahnrolle mit einer einzigen Vorratsrolle auskommt, d.h. man benötigt keine unterschiedlich breiten Verpakkungsbahnen mehr. Die Korpusverpackung ist über die axiale Länge der Materialbahnrolle sozusagen axial zusammengesetzt. Um die bisher bekannten Verpackungstechniken mit Stirndeckeln verwenden zu können, bei denen an die Stirnseiten der Materialbahnrollen jeweils ein Innenstirndeckel angelegt wird, ein axialer Überstand der Verpackungsbahn dann auf die Stirndeckel eingefaltet und schließlich ein Außenstirndeckel auf den eingefalteten Überstand und den Innenstirndeckel aufgebracht und befestigt wird, ergänzt man die Korpusverpackung mit der schraubenlinienförmig verlaufenden Verpackungsbahn durch mindestens eine Endverpackung, bei der die Verpackungsbahn unter Ausbildung eines axialen Überstandes in Umfangsrichtung um die Materialbahnrolle gewickelt wird. Hierbei liegt dann die Breitenerstreckung der Verpackungsbahn parallel zur Achse der Materialbahnrolle, während sie beim Herstellen der Korpusverpackung unter einem spitzen Winkel zur Achse der Materialbahnrolle verläuft.Packaging of this type has the advantage of being independent on the width of the roll of material to be packed manages with a single supply roll, i.e. no different widths of packaging lines are required more. The body packaging is over the axial length of the material web roll, so to speak, axially composed. To the previously known packaging techniques to be able to use with end covers where to the end faces of the web rolls Inner front cover is created, an axial protrusion the packaging web is then folded onto the front cover and finally an outer front cover on the folded one Protrusion and the inner front cover applied and attached, you add the body packaging with the helical packaging web by at least one final packaging in which the Packaging web with the formation of an axial protrusion wrapped in the circumferential direction around the roll of material web becomes. The latitude then lies here the packaging web parallel to the axis of the material web roll, while making the body package at an acute angle to the axis of the web roll runs.

Beim Herstellen der Korpusverpackung ergibt sich gelegentlich das Problem, daß das Ende der Verpackungsbahn nicht mit der gewünschten Zuverlässigkeit am Umfang der Materialbahnrolle haften bleibt. Dies tritt insbesondere dann auf, wenn ein Klebstoffauftrag aus irgendwelchen Gründen nicht bis zum Rand der Verpackungsbahn erfolgt, sondern einen Abstand dazu einhält. Während dies bei dem axial über die Materialbahnrolle überstehenden axial äußeren Ende der Verpackungsbahn unkritisch ist, weil hier ohnehin keine Materialbahnrolle mehr vorhanden ist, an der die Verpackungsbahn befestigt werden sollte, führt dies beim axial inneren Ende der Verpakkungsbahn dazu, daß dieser Zipfel nicht ausreichend befestigt wird und sich somit loslösen kann. Dies kann bei einer nachfolgenden weiteren Handhabung der verpackten Materialbahnrolle zu Beschädigungen der Verpakkung führen. Occasionally, when manufacturing the body packaging the problem that the end of the packaging line not with the desired level of reliability Material web roll sticks. This occurs in particular then when an adhesive application from any For reasons not up to the edge of the packaging line, but keep a distance from it. During this with the axially projecting over the web roll axially outer end of the packaging web is not critical, because there is no longer any web of material here to which the packaging web is attached should, this leads to the axially inner end of the packaging track to the fact that this tip is not sufficiently fastened will and can detach itself. This can in a subsequent further handling of the packaged Material web roll to damage the packaging to lead.

US-A-39 28 939 beschreibt ein Verfahren zum Verpacken von länglichen zylindrischen Objekten mit einer Kunststoffolie, bei dem die Kunststoffolie zunächst an einem Ende des Objekts in Umfangsrichtung um das Objekt herumgewickelt wird. Danach wird die gleiche Folie etwas geneigt und legt sich dementsprechend schraubenlinienförmig um das Objekt herum. Wenn das andere Ende des Objekts erreicht wird, fährt der Folienspender ein Stück zurück und es wird durch Weiterdrehen des Objekts eine Endverpackung erzeugt. Danach wird das mit Folie umhüllte Objekt durch einen Wärmeofen gefahren, in dem die Kunststoffolie auf das Objekt schrumpft.US-A-39 28 939 describes a method of packaging of elongated cylindrical objects with a plastic film, in which the plastic film first on one End of the object wrapped around the object in the circumferential direction becomes. After that, the same slide becomes something accordingly inclined and lies helically around the object. If the other end of the Object is reached, the film dispenser retracts Piece back and it is done by rotating the object creates a final packaging. Then it’s covered with foil enveloped object passed through a heating furnace in which the plastic film shrinks onto the object.

Der Erfindung liegt die Aufgabe zugrunde, eine Verpakkung zu erzeugen, die gegen die oben genannten Beschädigungen unempfindlicher ist.The invention has for its object a packaging to generate against the damage mentioned above is less sensitive.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Verpackungsbahn beim Bilden der Korpusverpackung mit ihrem axial äußeren Ende soweit axial über das Ende der Materialbahnrolle hinausgeführt wird, daß das axial innere Ende der Verpackungsbahn beim nachfolgenden Bilden der Endverpackung von der Endverpackung abgedeckt wird.This object is achieved in that the packaging web when forming the carcass packaging with its axially outer end as far axially over the end the web roll is led out that the axially inner end of the packaging web during subsequent forming the final packaging is covered by the final packaging becomes.

Auch wenn am Ende der Verpackungsbahn die Ecke, die axial innen liegt und die im folgenden als "innerer Zipfel" bezeichnet wird, nicht mit der notwendigen Zuverlässigkeit an dem Umfang der Materialbahnrolle oder einer zuvor aufgebrachten Windung der Verpackungsbahn angeklebt wird, wird sie zuverlässig an der Materialbahnrolle gehalten, weil sie von der Endverpackung abgedeckt wird. Damit kann die Verpackung der Materialbahnrolle nicht mehr dadurch beschädigt werden, daß dieser Zipfel frei kommt und die Verpackungsbahn ausgehend von dem Zipfel einreißt. Diese Vorgehensweise bedingt allerdings, daß die die Korpusverpackung bildende Verpackungsbahn axial ein Stück weit über die Stirnseite der Materialbahnrolle vorsteht. Es handelt sich hierbei allerdings nur um eine einzelne Lage der Verpackungsbahn, die beim nachfolgenden Einfalten des Überstandes der Endverpackung nicht nennenswert stört. In einem relativ großen Umfangsbereich hat der axiale Überstand der Korpusverpackung auch nur eine relativ geringe axiale Erstreckung. Man kann diesen Überstand also durchaus auch dann in Kauf nehmen, wenn beabsichtigt ist, die verpackten Materialbahnrollen in einer Kaminstapelung übereinander zu lagern.Even if at the end of the packaging line the corner that lies axially on the inside and is referred to below as "inner Point "is not referred to with the necessary reliability on the circumference of the material web roll or a previously applied turn of the packaging web is glued, it is reliably attached to the roll of material kept because they are covered by the final packaging becomes. This enables the packaging of the roll of material no longer be damaged by the fact that this corner comes free and the packaging line goes out tears from the tip. This procedure requires however, that the body packaging Packing lane axially a little way over the end face protrudes the web roll. It is about however, only by a single layer of the packaging web, which when folding the Overhang of the final packaging does not significantly disrupt. In a relatively large circumferential area, the axial The body packaging only protruded relatively slight axial extension. You can use this supernatant So accept it even if you intend to is the packed web rolls in one Stack the stack of chimneys on top of each other.

In einer besonders bevorzugten Ausgestaltung ist vorgesehen, daß das axial innere Ende der Verpackungsbahn der Korpusverpackung in einem Bereich liegt, der von einem axial inneren Randstreifen der Verpackungsbahn der Endverpackung mit einer Breite von maximal 20 % der Breite der Verpackungsbahn abgedeckt wird. Mit anderen Worten ist vorgesehen, daß der Überstand des axial inneren Endes der Verpackungsbahn der Endverpackung über das axial innere Ende der Verpackungsbahn der Korpusverpackung maximal 20 % der Breite der Verpackungsbahn beträgt. Bei dieser Ausgestaltung wird sichergestellt, daß der innere Zipfel der Korpusverpackung zwar abgedeckt wird. Diese Abdeckung liegt jedoch im Bereich des axial inneren Endes der Endverpackung, so daß der axiale Überstand der Korpusverpackung kleingehalten werden kann. Dies spart Verpackungsmaterial.In a particularly preferred embodiment, that the axially inner end of the packaging web the body packaging is in an area from an axially inner edge strip of the packaging web of the final packaging with a maximum width of 20% of the Width of the packaging line is covered. With others Words provide that the protrusion of the axially inner End of the packaging path of the final packaging the axially inner end of the packaging path of the carcass packaging maximum 20% of the width of the packaging line is. This configuration ensures that that the inner tip of the body packaging is covered becomes. However, this coverage is in the range of axially inner end of the end packaging, so that the axial Excess of the body packaging must be kept small can. This saves packaging material.

Auch ist bevorzugt, daß das Ende der Korpusverpackung vollständig von der Endverpackung abgedeckt wird. Dies erleichtert das nachfolgende Einfalten des axialen Überstandes der Endverpackung. Es besteht keine Gefahr, daß axial außen an der Korpusverpackung ein weiterer Zipfel entsteht, der zu einer Beschädigung führen könnte.It is also preferred that the end of the body packaging is completely covered by the final packaging. This facilitates the subsequent folding of the axial Protrusion of the final packaging. There is no danger that axially outside on the body packaging another Tip arises, which could lead to damage.

Vorzugsweise wird das axial überstehende Ende der Korpusverpackung frei von Klebstoff gehalten. Da das axial überstehende Ende der Korpusverpackung auf die Stirnseite der Materialbahn eingefaltet wird, besteht in ungünstigen Fällen die Gefahr, daß die Verpackungsbahn der Korpusverpackung an die Stirnseite der Materialbahnrolle kommt, wenn diese beispielsweise vom Innenstirndeckel nicht vollständig abgedeckt wird. Wenn man nun den axialen Überstand der Korpusverpackung frei von Klebstoff hält, dann besteht diese Gefahr nicht.The axially projecting end of the body packaging is preferred kept free of glue. Because that's axial protruding end of the body packaging on the front the material web is folded in, there are unfavorable Cases of danger that the packaging line the body packaging to the front of the roll of material comes, for example, from the inner front cover is not fully covered. If Now the axial overhang of the body packaging is free of Glue holds, then there is no danger.

Hierbei ist besonders bevorzugt, daß der Klebstoff in mehreren parallel verlaufenden Streifen aufgetragen wird, wobei mindestens ein Streifen auf dem axial überstehenden Teil früher endet als die anderen. Man stellt also hiermit sicher, daß die Verpackungsbahn zumindest axial weiter innen noch vollständig mit der Materialbahnrolle verklebt werden kann. Der Überstand bleibt jedoch frei. It is particularly preferred that the adhesive in applied several parallel stripes with at least one strip on the axially protruding Part ends earlier than the others. One poses so hereby ensure that the packaging web at least axially further inside with the web roll can be glued. The supernatant remains however free.

In einer alternativen Ausgestaltung ist vorgesehen, daß ein an Luft nach einer vorbestimmten Zeitdauer trocknender Klebstoff verwendet wird und der axiale Überstand der Endverpackung erst nach Ablauf der Zeitdauer auf die Stirnseite eingefaltet wird. Wenn der Klebstoff an der Luft trocknet, verliert er seine Klebfähigkeit. Ein Einfalten ist dann gefahrlos möglich, weil der axiale Überstand nicht mehr mit der Stirnseite verklebt.In an alternative embodiment it is provided that a drying in air after a predetermined period of time Adhesive is used and the axial protrusion the final packaging only after the period has expired is folded on the front. If the glue If it dries in the air, it loses its adhesiveness. Folding in is then possible without risk because of the axial protrusion is no longer glued to the face.

Hierbei ist besonders bevorzugt, daß die Zeitdauer mindestens so groß ist wie die zum Bilden der beiden Endverpackungen benötigte Zeit. Wenn man den axialen Überstand erst dann einfaltet, wenn die Endverpackungen vollständig hergestellt sind, dann muß diese Zeit ohnehin verstreichen. Es entstehen also keine zusätzlichen Totzeiten, die die Verpackung verlangsamen könnte.It is particularly preferred that the time period is at least is as large as that for forming the two end packs needed time. If you have the axial protrusion folds in only when the end packaging are completely manufactured, then this time must anyway elapse. So there are no additional ones Dead times that could slow down the packaging.

Die Erfindung wird im folgenden anhand eines bevorzugten Ausführungsbeispiels erläutert. Hierin zeigt die einzige Figur eine verpackte Materialbahnrolle.The invention is based on a preferred Exemplary embodiment explained. Herein shows the only figure a wrapped roll of material.

Die Figur zeigt eine verpackte Materialbahnrolle 1. Materialbahnrollen 1 dieser Art entstehen beispielsweise bei der Produktion von Papier oder textilen Warenbahnen. Sie haben eine beträchtliche Größe. Ihr Durchmesser liegt im Bereich 0,5 bis 2,5 m. Ihre axiale Länge liegt im Bereich von 0,5 bis 3,8 m oder sogar darüber hinaus. The figure shows a packaged web roll 1. Material web rolls 1 of this type arise, for example in the production of paper or textile webs. They are of considerable size. Your diameter lies in the range of 0.5 to 2.5 m. Your axial length is in the range of 0.5 to 3.8 m or even more out.

Dargestellt ist lediglich ein axiales Ende der Materialbahnrolle 1. Über die Länge ist die Materialbahnrolle 1 mit einer Korpusverpackung 2 versehen. An ihrem axialen Ende ist zusätzlich eine Endverpackung 3 angebracht. Diese Endverpackung 3 ist aus Gründen der Übersichtlichkeit mit einem etwas größeren Durchmesser als die Materialbahnrolle dargestellt. In Wirklichkeit liegt die Endverpackung 3 ebenfalls am Umfang der Materialbahnrolle 1 an.Only one axial end of the web of material web is shown 1. Over the length is the web roll 1 provided with a body packaging 2. On their axial End packaging 3 is additionally attached at the end. This final packaging 3 is for reasons of clarity with a slightly larger diameter than the roll of material shown. In reality the final packaging 3 is also on the circumference of the web roll 1 on.

Die Korpusverpackung 2 und die Endverpackung 3 werden aus der gleichen Verpackungsbahn 4 hergestellt. Die Verpackungsbahn besteht aus Packpapier und weist eine Breite von mindestens 350 mm auf. Damit läßt sich ein axialer Überstand 11 von 100 bis 150 mm am Ende der Materialbahnrolle 1 realisieren. Bewährt hat sich eine Verpackungsbahnbreite von etwa 500 mm. Zum Herstellen der Korpusverpackung 2 wird die Verpackungsbahn 4 schraubenlinienförmig um die Materialbahnrolle 1 herum geführt. Die Verpackungsbahn hat eine Breite B. Die Steigung der Schraubenlinie ist so eingestellt, daß sich aufeinanderfolgende Lagen der Verpackungsbahn 4 im vorliegenden Ausführungsbeispiel jeweils um B/2 überlappen. Dadurch entsteht eine zweilagige Korpusverpakkung 2. Natürlich kann man auch andere Verhältnisse zwischen Breite B und Steigung wählen, so daß man auch mehrlagige, beispielsweise drei- oder vierlagige Korpusverpackungen 2 herstellen kann. Die Überlappung ist dadurch dargestellt, daß der jeweils rechte Rand der Verpackungsbahn 4 in der Figur gestrichelt eingezeichnet ist. Es ist also von der nachfolgenden Verpackungsbahnlage abgedeckt.The body packaging 2 and the final packaging 3 are made from the same packaging web 4. The Packing lane consists of wrapping paper and has one Width of at least 350 mm. With that one can axial projection 11 from 100 to 150 mm at the end of the Realize web roll 1. One has proven itself Packaging web width of about 500 mm. To make the carcass packaging 2 becomes the packaging web 4 helically around the material web roll 1 guided. The packaging web has a width B. The The pitch of the helix is set so that successive layers of the packaging web 4 in overlap the present embodiment by B / 2. This creates a two-layer body package 2. Of course you can also use other conditions choose between width B and slope, so that you also multilayer, for example three or four-layer body packaging 2 can produce. The overlap is represented by the fact that the respective right edge of the Packaging web 4 shown in dashed lines in the figure is. So it is from the subsequent packaging web location covered.

Die Verpackungsbahn 4 ist im Bereich ihrer Ränder mit Leimraupen 5, 6 versehen, d.h. mit einem annähernd linienförmigen Klebstoffauftrag, so daß sie beim Herstellen der Korpusverpackung über ihre gesamte Länge mit der Materialbahnrolle bzw. mit zuvor aufgebrachten Lagen der Verpackungsbahn 4 verklebt wird.The packaging web 4 is in the area of its edges Glue beads 5, 6 provided, i.e. with an almost linear shape Apply glue so that when manufacturing the body packaging along its entire length the roll of material web or with previously applied layers the packaging web 4 is glued.

Die Verpackungsbahn 4 endet an einer Schnitt- oder Trennlinie 7. Dort ergibt sich dann am axial inneren Ende ein innerer Zipfel 8 und am axial äußeren Ende ein äußerer Zipfel 9. Der äußere Zipfel 9 liegt hierbei in einem Bereich der Verpackungsbahn 4, der axial über die Stirnseite 10 der Materialbahnrolle 1 übersteht.The packaging line 4 ends at a cutting or Dividing line 7. There is then on the axially inner End an inner tip 8 and at the axially outer end outer tip 9. The outer tip 9 lies in an area of the packaging web 4 which is axially across the End 10 of the web roll 1 protrudes.

Die Endverpackung 3 besteht aus mindestens einer Lage, üblicherweise aber mehreren Lagen der Verpackungsbahn 4, die in Umfangsrichtung unter Ausbildung eines axialen Überstandes 11 um die Materialbahnrolle 1 gewickelt ist.The final packaging 3 consists of at least one layer, but usually several layers of the packaging web 4, the circumferential direction forming an axial Overhang 11 wrapped around the web roll 1 is.

Man stimmt nun das Ende der Verpackungsbahn 4 der Korpusverpackung 2, d.h. die Lage der Schnitt- oder Trennlinie 7, so auf die Lage der Endverpackung 3 ab, daß die Schnitt- oder Trennlinie 7 vollständig von der Endverpackung 3 abgedeckt wird. Damit wird zum einen sichergestellt, daß der innere Zipfel 8 von der Endverpackung abgedeckt wird. Es ist aus der Figur ersichtlich, daß die Leimraupe 5 zwar im Bereich des Randes der Verpackungsbahn 4 angeordnet ist, zu diesem jedoch einen kleinen Abstand aufweist. Dies führt dazu, daß sich der innere Zipfel 8 von der Materialbahnrolle 1 lösen kann. Dadurch, daß die Endverpackung 3 den inneren Zipfel 8 abdeckt, ist diese Gefahr jedoch beseitigt worden.The end of the packaging line 4 of the carcass packaging is now correct 2, i.e. the location of the cutting or dividing line 7, so on the location of the final packaging 3 that the cutting or dividing line 7 completely from the final packaging 3 is covered. On the one hand, this ensures that the inner tip 8 of the final packaging is covered. It can be seen from the figure that the glue bead 5 in the region of the edge the packaging web 4 is arranged, but to this has a small distance. This leads to the inner tip 8 of the material web roll 1 can solve. Characterized in that the final packaging 3 the inner Covering corner 8, this danger is eliminated been.

Auch der äußere Zipfel 9 wird von der Endverpackung 3 abgedeckt. Auch hier besteht dann keine Gefahr mehr, daß er vorsteht. Dies könnte zu einer Angriffsstelle für Beschädigungen werden. The outer tip 9 is also from the final packaging 3 covered. Here, too, there is no longer any danger that he stands out. This could become a point of attack for damage.

Nach dem Herstellen der Endverpackung 3 wird an sich bekannter Weise, beispielsweise mit Flügelrädern, der axiale Überstand 11 der Endverpackung 3 auf die Stirnseite 10 der Materialbahnrolle 1 eingefaltet. Gegebenenfalls kann noch ein Innenstirndeckel vorher eingebracht werden.After the production of the final packaging 3 is in itself known manner, for example with impellers, the axial projection 11 of the final packaging 3 on the end face 10 of the material web roll 1 folded. Possibly an inner front cover can be inserted beforehand become.

Um zu verhindern, daß beim Einfalten des axialen Überstandes 11 bzw. des äußeren Zipfels 9 die Verpackungsbahn 4 der Korpusverpackung 2 mit der Stirnseite 10 verklebt, kann man die Leimraupe 6 vor der Trennlinie 7 enden lassen. Man kann sich ausrechnen, wann die Leimraupe 6 enden muß, damit sie sich nicht mehr in den Bereich des axialen Überstandes der Hauptverpackung 2 erstreckt. Dort ist ein Klebstoffauftrag ohnehin nicht mehr notwendig, weil nichts mehr zur Verfügung steht, mit dem die Verpackungsbahn 4 verklebt werden könnte.In order to prevent that when the axial protrusion is folded in 11 or the outer tip 9 the packaging web 4 of the body packaging 2 with the end face 10 glued, you can glue bead 6 in front of the dividing line 7th let it end. You can calculate when the glue bead 6 must end so that it no longer fits into the Axial projection of the main packaging 2 extends. There is no glue application there anyway more necessary because nothing is available, with which the packaging web 4 could be glued.

Alternativ dazu kann man auch einen Klebstoff verwenden, der seine Klebefähigkeit verliert, wenn er eine bestimmte Zeitdauer der Umgebungsatmosphäre ausgesetzt ist. Dieses Verhalten läßt sich bei vielen Klebstoffen beobachten. Da für das Herstellen der Endverpackungen 3 an beiden Enden der Materialbahnrolle 1 ohnehin eine gewisse Zeit benötigt wird, kann man durch eine entsprechende Auswahl des Klebstoffs ein Verkleben des Überstandes der Korpusverpackung 2 mit der Stirnseite 10 der Materialbahnrolle verhindern.Alternatively, you can use an adhesive who loses its adhesiveness if it has one exposed to the surrounding atmosphere for a certain period of time is. This behavior can be seen with many adhesives observe. As for the production of the final packaging 3 at both ends of the material web roll 1 anyway a certain amount of time is required by a corresponding one Selection of the adhesive a sticking of the Protrusion of the body packaging 2 with the front Prevent 10 of the web roll.
