Description
Die Erfindung bezieht sich auf ein Verfahren zum Überleiten einer Materialbahn von einer Wickelrolle zu einer Wickelhülse, bei dem die Bahn in Querrichtung völlig durchgeschnitten und mit doppelseitigem Klebeband versehen wird sowie in einem Übergabebereich das Bahnende an die Wickelrolle und der Bahnanfang an die Wikkelhülse angeklebt wird, und auf eine Wickelvorrichtung für eine Materialbahn mit einer Schneidvorrichtung zum völligen Durchschneiden der Materialbahn in Querrichtung, einer Auftragsvorrichtung für doppelseitiges Klebeband und einem Übergabebereich, in welchem das Bahnende an eine Wickelrolle und der Bahnanfang an eine Wickelhülse angeklebt wird.The invention relates to a method for transferring a web of material from a winding roll to one Winding tube, in which the web in the transverse direction completely cut through and with double-sided adhesive tape is provided as well as the web end in a transfer area to the winding roll and the beginning of the web to the winding sleeve is glued, and on a winding device for a material web with a cutting device for complete cutting of the material web in the transverse direction, an application device for double-sided adhesive tape and a transfer area in which the web end to a winding roll and the beginning of the web to one Winding sleeve is glued.
Ein solcher Stand der Technik ist aus EP 0 512 196 B1 bekannt. Die Schneidvorrichtung und die Klebeband-Auftragsvorrichtung befinden sich im Übergabebereich, also an derjenigen Stelle, wo durch Zertrennen der Materialbahn ein vorlaufendes Bahnende und nachlaufender Bahnanfang entstanden sind, die unterschiedlich behandelt werden müssen, um an der Wickelrolle bzw. an der Wickelhülse angeklebt zu werden. Allerdings bringt diese Anordnung der Schneidvorrichtung und der Auftragsvorrichtung Platzprobleme mit sich und engt die konstruktive Freiheit ein.Such prior art is known from EP 0 512 196 B1 known. The cutter and the tape applicator are in the transfer area, So at the point where by cutting the web of material one leading and one trailing end The beginning of the web have arisen, which are treated differently have to be on the winding roll or on the Winding sleeve to be glued. However, this brings Arrangement of the cutting device and the application device Space problems with themselves and narrow the constructive Freedom one.
Aus EP 0 442 038 B1 ist es bekannt, die Materialbahn mit Abstand vor dem Übergabebereich durch eine Perforierung zu schwächen und beidseitig der Perforierung mit doppelseitigem Klebeband zu versehen. Die Bahn wird dann weiter transportiert bis sich die Perforierung im Übergabebereich befindet. Dort soll durch Erhöhung der Bahnspannung die Bahn längs der Perforierung zerrissen werden. Hierbei muß die Perforiervorrichtung dem jeweils zu wickelnden Material angepaßt werden, damit die Schwächung einerseits nicht zu groß ist und die Bahn schon bei der normalen Transportspannung reißt und andererseits groß genug ist, damit die Bahn im Übergabebereich auch tatsächlich zertrennt wird.The material web is known from EP 0 442 038 B1 at a distance from the transfer area through perforation to weaken and bilateral perforation to be provided with double-sided adhesive tape. The web will then transported until the perforation in the Transfer area is located. There is said to be by increasing the Web tension tore the web along the perforation become. Here, the perforating device must be the be adapted to the winding material so that the Weakening on the one hand is not too big and the web tears at the normal transport tension and on the other hand is large enough so that the web in the transfer area is actually separated.
WO 92/05100 A1 zeigt ein Verfahren und eine Vorrichtung zum Wechseln von Wickelrollen. Die Wickelrollen liegen hierbei in einem Wickelbett, das durch zwei Tragwalzen gebildet ist. Die zulaufende Materialbahn umschlingt eine Tragwalze und wird der Wickelrolle durch das Wikkelbett hindurch zugeführt. In einem gewissen Abstand vor dem Wickelbett ist eine Perforationseinrichtung vorgesehen, mit der die Materialbahn geschwächt werden kann. Eine Strecke hinter der Perforationseinrichtung ist ein Klebemittelspender vorgesehen, der eine Walze aufweist, die eine geringere Adhäsion gegenüber dem Klebemittel aufweist als die Materialbahn. Nach dem Perforieren wird die Materialbahn weiter vorgezogen. WO 92/05100 A1 shows a method and a device for changing winding rolls. The winding rolls are lying here in a changing bed, which is supported by two support rollers is formed. Loops around the incoming material web a support roller and the winding roll is through the winding bed fed through. At a certain distance There is a perforation device in front of the changing bed provided with which the material web are weakened can. A stretch behind the perforation device an adhesive dispenser is provided, which is a roller has a lower adhesion to the Has adhesive as the material web. After this Perforating the material web is further preferred.
Das Klebemittel ist auf die Übergabewalze so aufgetragen worden, daß beim Vorziehen das Klebemittel so gegenüber der Materialbahn positioniert wird, daß das Klebemittel die Perforationslinie übergreift. Beim Ausstoßen der Wickelrolle aus dem Wickelbett muß die Materialbahn an der durch die Perforation geschwächten Linie und zusätzlich das Klebeband durchgerissen werden.The adhesive is applied to the transfer roller in this way been so that when pulling the adhesive over the material web is positioned that the Adhesive overlaps the perforation line. When expelling the winding roll from the winding bed must be the material web on the weakened by the perforation Line and also the tape must be torn.
Der Erfindung liegt die Aufgabe zugrunde, den Übergabebereich von der Schneidvorrichtung und der Klebeband-Auftragsvorrichtung frei zu halten, ohne daß die mit der Schwächung der Materialbahn verbundenen Schwierigkeiten auftreten.The invention has for its object the transfer area from the cutter and the tape applicator to keep free without having to difficulties associated with weakening the web occur.
Diese Aufgabe wird verfahrensmäßig dadurch gelöst, daß die Bahn mit Abstand vor dem Übergabebereich durchgeschnitten und die Schnittlinie noch während des Schneidens mit dem Klebeband überklebt wird, daß die Bahn weiter transportiert wird, bis sich die Schnittlinie im Übergabebereich befindet, und daß dort durch Erhöhung der Bahnspannung das Klebeband zerrissen wird. This task is solved procedurally in that cut the web at a distance in front of the transfer area and the cutting line while cutting is taped over with the tape that the web is transported further until the cutting line in the Transfer area is located, and that there by increasing the web tension the tape is torn.
Bei diesem Vorgehen wird die Bahn schon vor Erreichen des Übergabebereichs vollständig durchgeschnitten. Man erhält daher bei der endgültigen Trennung saubere Kanten. Das Klebeband übernimmt als zweite Funktion die für den Weitertransport der Materialbahn erforderliche Verbindung zwischen dem vorlaufenden Bahnende und dem nachlaufenden Bahnanfang. Die zum endgültigen Trennen von Bahnende und Bahnanfang erforderliche Zerreißkraft, also die erforderliche Erhöhung der Bahnspannung, ist durch die Reißfestigkeit des Klebebandes vorgegeben. Anpassungen an das Bahnmaterial sind nicht oder nur in seltenen Fällen erforderlich. Da die Reißfestigkeit des Klebebandes bekannt ist, kann man es von vornherein so wählen, daß optimale Betriebsverhältnisse entstehen. Da die Schnittlinie noch während des Schneidens mit dem Klebeband überklebt wird, werden Bahnende und Bahnanfang trotz des vollständigen Durchschneidens ständig aneinander gehalten. Da Schneiden und Kleben in einem Arbeitsgang erfolgen, wird der Überleitungsvorgang verkürzt.With this procedure, the train is reached before of the transfer area completely cut. you therefore receives clean edges during the final separation. The adhesive tape takes over as the second function required for the further transport of the material web Connection between the leading web end and the trailing start of the path. The final disconnect tensile strength required at the end and at the beginning of the path, thus the required increase in web tension determined by the tear strength of the adhesive tape. Adjustments to the web material are not or only in rare cases required. Because the tensile strength of the Adhesive tape is known, you can do it from the start choose that optimal operating conditions arise. There the cutting line while cutting with the Adhesive tape is stuck over, the web end and web start despite being completely cut through held together. Because cutting and gluing in one Operation, the transfer process is shortened.
Mit Vorteil umfaßt der Übergabebereich das Wickelbett eines Tragwalzenwicklers. Bei dieser Anwendung ist es besonders wichtig, den Übergabebereich von Schneidvorrichtung und Auftragsvorrichtung frei zu halten.The transfer area advantageously includes the changing bed a winder. With this application it is particularly important, the transfer area of the cutting device and to keep application device free.
Vorzugsweise erfolgt das Zerreißen des Klebebandes beim Ausstoßen der Wickelrolle. Hierbei tritt die erhöhte Bahnspannung auf, wenn jenseits der Schnittlinie die Bahn festgehalten oder gebremst wird. Da für das Zerreißen kein gesonderter Arbeitsgang benötigt wird, ergibt sich ein rascher Überleitvorgang. The adhesive tape is preferably torn when Eject the winding roll. Here the increased occurs Web tension on if beyond the cutting line Web is held or braked. As for tearing no separate operation is required a quick transition process.
Günstig ist es auch, daß die Wickelrolle nach dem Zerreißen des Klebebandes allein durch den Ausstoßvorgang bewegt und hierbei das Bahnende an den Wickelrollenumfang längs einer Linie gedrückt wird, die in Umfangsrichtung wandert, bis das Bahnende angeklebt ist. Bei dieser Maßnahme ist es unnötig, den Rotationsantrieb der Wickelrolle nochmals zu betätigen, um das Bahnende anzukleben.It is also favorable that the winding roll after tearing of the adhesive tape solely by the ejection process moves and the end of the web to the circumference of the winding roll is pressed along a line that is circumferential wanders until the end of the web is glued. at this measure, it is unnecessary to use the rotary drive of the winding roll again to the end of the web to glue.
Eine konstruktive Lösung der gestellten Aufgabe besteht darin, daß die Schneidvorrichtung und die Auftragsvorrichtung mit Abstand vor dem Übergabebereich angeordnet sind und daß die Auftragsvorrichtung der Schneidvorrichtung folgt und die zuvor erzeugte Schnittlinie mit dem Klebeband überklebt. Es ergeben sich die gleichen Vorteile, wie sie in Verbindung mit dem erfindungsgemäßen Verfahren beschrieben worden sind.There is a constructive solution to the task at hand in that the cutter and the applicator arranged at a distance from the transfer area are and that the application device of the cutting device follows and the previously created cutting line with taped over the tape. The same result Advantages such as those in connection with the invention Procedures have been described.
Empfehlenswert ist es, daß zwei Tragwalzen für die Wikkelrolle vorgesehen sind und der Übergabebereich das Wickelbett der Tragwalzen umfaßt.It is recommended that two support rollers for the winding roll are provided and the transfer area that Includes winding bed of the support rollers.
Vorzugsweise sind Schneidvorrichtung und Auftragsvorrichtung an einem gemeinsamen quer zur Materialbahn verlagerbaren Träger angebracht. So lassen sich Schneidvorrichtung und Auftragsvorrichtung in geringem Abstand voneinander halten, so daß der nicht vom Klebeband überklebte Abschnitt der Schnittlinie kurz ist.The cutting device and application device are preferred on a common cross to the material web movable carrier attached. So you can Cutting device and application device in small Keep a distance from each other so that the tape is not pasted section of the cutting line is short.
Insbesondere kann dem Wickelbett ein Ausstoßer benachbart sein, bei dessen Betätigung das Klebeband zerreißt. Es bedarf dann keiner weiteren Hilfsmittel zum Aufbringen der Zerreißkraft. In particular, an ejector can be adjacent to the changing bed be when the tape tears when pressed. No further aids are then required for Applying the tensile strength.
Günstig ist ferner ein an den Umfang einer Wickelrolle anlegbares Andruckelement, das sich bei der Ausstoßbewegung der Wickelrolle in Umfangsrichtung relativ zu ihr bewegt. Auf diese Weise ist ein Rotationsantrieb der Wickelrolle nach dem Zerreißen des Klebebandes unnötig.It is also advantageous to have the circumference of a winding roll pressure element that can be put on during the ejection movement the winding roll in the circumferential direction relative to you move. In this way it is a rotary drive the winding roll after tearing the tape unnecessary.
Konstruktiv empfiehlt es sich hierbei, daß der Ausstoßer ein Ausstoßerrohr aufweist, das an Ausstoßer-Hebeln gelagert ist, die um eine Achse unterhalb der Wickelrolle schwenkbar sind, und daß an den Ausstoßer-Hebeln Andruckhebel gelagert sind, die durch einen Hydrozylinder betätigbar sind und das Andruckelement tragen. Dies ergibt eine besonders einfache Ausführungsform.It is constructively recommended that the ejector has an ejector tube attached to ejector levers is mounted around an axis below the winding roll are pivotable, and that on the ejector levers Pressure levers are supported by a hydraulic cylinder can be operated and carry the pressure element. This results in a particularly simple embodiment.

Bei der Tragwalzen-Wickelvorrichtung der Fig. 1 wird
eine Bahn 1 aus Papier oder Karton, die in Pfeilrichtung
2 zuläuft, zu einer Wickelrolle 3 gewickelt. Diese
ruht auf zwei Tragwalzen 4 und 5, von denen wenigstens
eine angetrieben ist und damit auch die Wickelrolle 3
antreibt. Sobald die Wickelrolle 3 ihren maximalen
Durchmesser erreicht hat, muß die Bahn 1 in Querrichtung
durchtrennt werden, wenn sich die Trennstelle in
einem Übergabebereich 6, der das Wickelbett 7 umfaßt,
befindet, so daß das vorlaufende Bahnende an der Wikkelrolle
und der nachlaufende Bahnanfang an einer neuen
Wickelhülse 8 festgeklebt werden kann. Dies wird nachstehend
erläutert.In the support roller winding device of FIG. 1
a
Mit Abstand vor dem Übergabebereich 6 befindet sich eine
Baueinheit 9, die im wesentlichen eine Schneidvorrichtung
10 und eine Klebeband-Auftragsvorrichtung 11
umfaßt. Beide Vorrichtungen werden von einem gemeinsamen
Träger 12, beispielsweise einem Schlitten getragen,
der längs einer Schiene 13 in Richtung des Pfeiles 14
quer zur Materialbahn und wieder zurück verfahren werden
kann. Auf der gegenüberliegenden Seite der Materialbahn
befindet sich eine an die Bahn 1 heranschwenkbare
Gegenplatte 15 mit einer Nut 16, in die ein
Messer 17 der Schneidvorrichtung 10 eingreifen kann.
Die Auftragsvorrichtung 11 weist kurz hinter dem Messer
17 einen Auftragsbereich 18 auf, an welchem ein doppelseitig
wirkendes Klebeband 19, das von einer Vorratsrolle
20 abgezogen wird, auf die Bahn 1 aufgetragen
wird, worauf ein Trägerband auf einer Abfallrolle 21
aufgewickelt wird.There is one at a distance from the
In Fig. 3 ist die Wirkung dieser Einheit 9 zu ersehen.
Die Schneidvorrichtung 10 erzeugt mit dem kontinuierlich
arbeitenden Schneidmesser 17 eine das Bahnmaterial
vollständig durchschneidende Schnittlinie 22. Diese
Schnittlinie ist aber durch das Klebeband 19 vollständig
überklebt. Demzufolge ist zwar ein vorlaufendes
Bahnende 23 und ein nachlaufender Bahnanfang 24 geschaffen;
beide werden aber durch das Klebeband 19 zusammengehalten.
Diese Maßnahme erfolgt bei stillstehender
Bahn 1.
Die Bahn 1, die über zwei Leitwalzen 25 und 26 sowie
eine Breitstreckwalze 27 zugeführt wird, wird hierbei
mittels eines ersten Klemmelements 28 an der Leitwalze
26 und mittels eines zweiten Klemmelements 29 an der
Tragwalze 4 festgeklemmt, so daß die Schnittlinie 22
nicht unter Spannung steht.The effect of this
Anschließend wird die Bahn 1 wieder angetrieben, bis
sich die Schnittlinie 22 im Übergabebereich 6 befindet.
Dann wird mit dem Klemmelement 29 die Bahn 1 erneut an
der Tragwalze 4 festgeklemmt und ein Ausstoßer 30 betätigt,
der die Wickelrolle 3 nach rechts ausstößt. Hierdurch
wird die Bahnspannung erhöht und das Klebeband 19
zerreißt längs der Schnittlinie 22. Nunmehr sind Bahnende
23 und Bahnanfang 24 frei und können an der Wikkelrolle
3 bzw. einer neuen Wickelhülse 8 festgeklebt
werden.Then the
Der Ausstoßer 30 ist mit einem Ausstoßerrohr 31 versehen,
das am Umfang der Wickelrolle 3 angreift und an
Ausstoßer-Hebeln 32 gelagert ist, die um den Drehpunkt
33 der Tragwalze 4 mit Hilfe eines nicht veranschaulichten,
am Ausleger 34 angreifenden Hydrozylinders
schwenkbar sind. An den Ausstoßer-Hebeln 32 ist auch
eine Aufnahme 35 für eine neue Wickelhülse 8' vorgesehen,
die beim Ausstoßen automatisch in das Wickelbett 7
fällt. Ferner wird die Gegenplatte 15 von den Ausstoβer-Hebeln
32 getragen.The
Des weiteren sind an den Ausstoßer-Hebeln 32 Andruckhebel
36 gelagert, die durch Hydrozylinder 37 verschwenkt
werden können und am freien Ende ein Andruckelement 38
in der Form einer geteilten Andruckrolle tragen. Dieses

durch den Spalt zwischen den Tragwalzen 4 und 5 geschoben
und in die gestrichelte Lage gebracht werden kann.Further aids are indicated schematically. A
Von dem dargestellten Ausführungsbeispiel kann in vielfacher Hinsicht abgewichen werden, ohne den Grundgedanken der Erfindung zu verlassen. Beispielsweise kann anstelle des Klemmelements 29 eine Tragwalze mit Saugvorrichtung verwendet werden. Das Erfindungsprinzip eignet sich nicht nur für Tragwalzenwickler, sondern auch für Wickler mit einer Stützwalze.The illustrated embodiment can be used in many different ways Terms are deviated without the basic idea to leave the invention. For example, instead of of the clamping element 29 a support roller with suction device be used. The principle of the invention is suitable is not only suitable for carrier roller winders, but also for Winder with a backup roller.
