Description

Die Erfindung betrifft eine Tragwalzenwickelmaschine zum Aufwickeln einer Materialbahn, insbesondere einer Papier- oder Kartonbahn, auf Wickelhülsen, mit einer Vorrichtung zum Einlegen einer neuen Wickelhülse in das Tragwalzenbett und zum Trennen der Materialbahn, bei der ein Aufnahmeelement für die Hülse und ein Bahntrennelement an einem Doppelgelenkhebel befestigt sind, der um eine Achse parallel zu einer Tragwalzenachse schwenkbar ist.The invention relates to a support roller winding machine for winding a material web, in particular a paper or cardboard web, on winding cores, with a device for inserting a new winding core into the carrier roller bed and for separating the material web, in which a receiving element for the sleeve and a web separating element on a double articulated lever are attached, which is pivotable about an axis parallel to a support roller axis.

Tragwalzenwickelmaschinen dienen insbesondere zum Aufwickeln von Papier- oder Kartonbahnen von einer Vorratsrolle auf einzelne kleinere Rollen, wobei gleichzeitig die von der Vorratsrolle abgezogene Bahn in Längsrichtung in Einzelbahnen geschnitten wird. Sie weisen zwei oder mehr Tragwalzen auf, wobei die Wickelrollen in Achsrichtung nebeneinander in dem Tragwalzenbett zwischen zwei Tragwalzen auf Hülsen aufgewickelt werden. Nachdem die Wickelrollen den gewünschten Durchmesser erreicht haben, werden die von der Vorratsrolle kommenden, längsgeschnittenen Einzelbahnen durchgetrennt, die vollen Wickelrollen entladen und neue Wickelhülsen in das Tragwalzenbett eingelegt, an die die neugebildeten Bahnanfänge der Einzelbahnen angewickelt werden.Carrier roll winding machines are used, in particular, for winding paper or cardboard webs from a supply roll onto individual smaller rolls, at the same time the web drawn off from the supply roll being cut into individual webs in the longitudinal direction. They have two or more support rollers, the winding rollers being wound up in the axial direction next to one another in the support roller bed between two support rollers on sleeves. After the winding rolls have reached the desired diameter, the ones coming from the supply roll are cut lengthways Separate individual webs, unload the full winding rolls and insert new winding tubes in the carrier roller bed, to which the newly formed start of the individual webs are wound.

Aus der DE-AS 29 30 474 ist eine Tragwalzenwickelmaschine bekannt, bei der eine Perforierleiste an einem zwischen zwei Schilden gehaltenen Schalensegment befestigt ist, das um eine zur Tragwalzenachse parallele, aber exzentrisch angeordnete Achse schwenkbar ist. An den Schilden sind Hebel schwenkbar gelagert, die zwischen sich eine muldenförmige Aufnahme für einen neuen Wickelkern tragen. Die Hebel und damit die Aufnahmemulde mit dem neuen Wickelkern können relativ zu den Schilden verschwenkt werden, bis die Aufnahmemulde sich über dem Spalt zwischen den beiden Tragwalzen befindet. Die Durchtrennung der Bahn erfolgt durch Ausstoß einer vollen Wickelrolle aus dem Tragwalzenbett, wobei die Bahn an der perforierten Stelle durchreißt. Während der neu gebildete Bahnanfang an der Tragwalze festgeklemmt wird, wird eine neue Wickelhülse in das Tragwalzenbett eingelegt.From DE-AS 29 30 474 a carrier roller winding machine is known, in which a perforating strip is fastened to a shell segment held between two shields, which can be pivoted about an axis which is parallel to the carrier roller axis but is arranged eccentrically. Levers are pivotally mounted on the shields and carry a trough-shaped receptacle for a new winding core between them. The lever and thus the receiving trough with the new winding core can be pivoted relative to the shields until the receiving trough is located above the gap between the two support rollers. The web is severed by ejecting a full winding roll from the carrier roller bed, the web tearing at the perforated point. While the newly formed start of the web is clamped onto the support roller, a new winding tube is inserted into the support roller bed.

An dieser Vorrichtung ist nachteilig, daß die Stelle, an der die Bahn durchgetrennt wird, nicht variierbar ist. Es hat sich gezeigt, daß bei Verwendung von Hülsen mit unterschiedlichem Durchmesser Probleme beim Befestigen des neuen Bahnanfangs an der neuen Wickelhülse auftreten, falls die Länge des Bahnanfangs bis zur Berührungslinie der Wickelhülse an die Tragwalze nicht dem jeweiligen Hülsendurchmesser angepaßt ist. Bei Hülsen mit größerem Durchmesser muß die Länge des Bahnanfangs zwischen der Durchtrennlinie und der Anliegelinie der Wickelhülse an die Tragwalze größer sein, als bei Wickelhülsen mit kleinerem Durchmesser.A disadvantage of this device is that the point at which the web is severed cannot be varied. It has been shown that when using sleeves with different diameters problems arise when attaching the new web start to the new winding tube if the length of the web start up to the line of contact of the winding tube with the support roller is not adapted to the respective tube diameter. In the case of cores with a larger diameter, the length of the beginning of the web between the severing line and the line of contact of the winding core with the support roller must be greater than in the case of winding cores with a smaller diameter.

Um u. a. auch die Position der Trennlinie unterschiedlichen Hülsendurchmessern anzupassen, ist es aus der DE-PS 31 51 256 bekannt, eine schwenkbare bauliche Einheit aus Heft- und Schneidvorrichtung quer zur Achse der Tragwalzen verschiebbar zu gestalten. Die dort gezeigte Lösung erfordert jedoch eine getrennt schwenkbare Vorrichtung zum Einlegen einer neuen Wickelhülse.In order to adapt the position of the dividing line to different sleeve diameters, among other things, it is known from DE-PS 31 51 256 to make a pivotable structural unit consisting of a stapling and cutting device displaceable transversely to the axis of the support rollers. However, the solution shown there requires a separately pivotable device for inserting a new winding tube.

Die DE-A 36 40 724 zeigt eine gattungsgemäße Tragwalzenwickelmaschine, bei der ein Aufnahmeelement für die neue Hülse und ein Trennelement um die umschlungene Tragwalze eingeschwenkt werden. Da die Hülse auf ihrem Weg in die Endposition im Tragwalzenbett den Verlauf der Bahn kreuzt, muß diese durchgetrennt werden, bevor die Hülse eingelegt wird. Um die Bahn beim Trennen zu halten, ist eine zusätzliche Haltevorrichtung erforderlich. Mittel zur Anpassung der Trennlinie der Bahn in Abhängigkeit von unterschiedlichen Hülsendurchmessern sind nicht vorhanden.DE-A 36 40 724 shows a generic carrier roller winding machine in which a receiving element for the new sleeve and a separating element are pivoted about the wrapped carrier roller. Since the sleeve crosses the path of the web on its way to the end position in the carrier roller bed, it must be severed before the sleeve is inserted. An additional holding device is required to hold the web when it is cut. There are no means of adapting the dividing line of the web depending on different sleeve diameters.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Tragwalzenwickelmaschine mit an einem gemeinsamen Schwenkarm befestigten Hülsenaufnahmeelement und Bahntrennelement zu schaffen, bei der konstruktiv einfach die Position der Trennlinie der Bahn in Abhängigkeit vom Hülsendurchmesser veränderbar ist.The invention has for its object to provide a generic carrier roll winding machine with a sleeve arming element and web separation element fastened to a common swivel arm, in which the position of the dividing line of the web can be changed in a structurally simple manner depending on the tube diameter.

Die erfindungsgemäße Tragwalzenwickelmaschine weist zwei Tragwalzen 1, 2 auf, zwischen denen ein Walzenbett 3 ausgebildet ist, in dem die Wickelrollen während des Aufwickelns auf den Tragwalzen 1, 2 aufliegen. Die Materialbahn 4 - vorzugsweise eine Papier- oder Kartonbahn - wird von unten, von der Tragwalze 1 umgelenkt durch den Spalt zwischen den Tragwalzen 1, 2 in das Wickelbett 3 geführt. Derartige Doppeltragwalzenwickelmaschinen sind bekannt, auf konstruktive Einzelheiten wird daher nicht näher eingegangen.The support roller winding machine according to the invention has two support rollers 1, 2, between which a roller bed 3 is formed, in which the winding rollers rest on the support rollers 1, 2 during winding. The material web 4 - preferably one Paper or cardboard web - is guided from below, deflected by the support roller 1 through the gap between the support rollers 1, 2 into the winding bed 3. Such double carrier roller winding machines are known, so design details are not discussed in detail.

An jeder Stirnseite der Tragwalze 2 ist im Rahmen der Wickelmaschine jeweils ein Einschwenkhebel 5 um eine Achse Parallel zur Tragwalzenachse schwenkbar angelenkt; im vorliegenden Beispiel verläuft die Schwenkachse koaxial zur Drehachse der Tragwalze 2. Am anderen Ende der Einschwenkhebel 5 ist jeweils ein weiterer Schwenkhebel 6 angelenkt, der mittels einer zwischen ihm und dem Einschwenkarm 5 befestigten Kolben-Zylinder-Einheit 7 relativ zum Einschwenkhebel 5 verschwenkbar ist, wobei die Schwenkbewegung in Richtung des Einschwenkhebels 5 durch einstellbare Anschläge 8 begrenzt ist. An den freien Enden der Schwenkhebel 6 ist eine sich quer über die Arbeitsbreite erstreckende Hülsenrinne 9 in einer angepaßten Aussparung befestigt. Die der Tragwalze 2 abgewandte Seite des freien Endes der Schwenkhebel 6 weist jeweils eine Verlängerung 10 auf, an deren Ende ein sich quer über die Arbeitsbreite erstreckendes Führungsrohr für ein parallel zur Tragwalzenachse bewegliches Trennmesser 11 befestigt ist. Die Verlängerungen 10 erstrecken sich in etwa bis in den Bereich der Scheitellinie einer in die Hülsenrinne 9 eingelegten Wickelhülse mit maximalem Durchmesser.On each end face of the support roller 2, a pivoting lever 5 is articulated in the frame of the winding machine about an axis parallel to the support roller axis; In the present example, the pivot axis runs coaxially to the axis of rotation of the support roller 2. At the other end of the pivoting lever 5, a further pivot lever 6 is articulated, which can be pivoted relative to the pivoting lever 5 by means of a piston-cylinder unit 7 fastened between it and the pivoting arm 5, the pivoting movement in the direction of the pivoting lever 5 being limited by adjustable stops 8. At the free ends of the pivot lever 6, a sleeve groove 9 extending across the working width is fastened in an adapted recess. The side of the free end of the pivoting lever 6 facing away from the support roller 2 has an extension 10, at the end of which a guide tube extending transversely across the working width is attached for a separating knife 11 movable parallel to the support roller axis. The extensions 10 extend approximately to the area of the apex line of a winding tube of maximum diameter inserted into the tube groove 9.

Die Schwenkbewegung der Einschwenkhebel 5 wird mittels koaxial zu ihrer Schwenkachse befestigten Kettenrädern 12 durchgeführt, die über Ketten 13 von einer sich quer über die Arbeitsbreite erstreckenden, angetriebenen Drehpunktwelle 14 mit Kettenrädern 15 an beiden Enden angetrieben werden. Die Welle 14 gewährleistet ebenfalls eine synchrone Einschwenkbewegung an beiden Stirnseiten der Tragwalze 2.The pivoting movement of the pivoting-in levers 5 is carried out by means of chain wheels 12 which are fastened coaxially to their pivot axis and which are driven by chains 13 by a driven pivot shaft 14 with chain wheels 15 at both ends which extends across the working width. The shaft 14 also ensures a synchronous pivoting-in movement on both end faces of the support roller 2.

Zum manuellen Befestigen des neu gebildeten Bahnanfangs an den neuen Wickelhülsen 16, 17 ist eine schwenkbare Begehungsplattform 18 neben der Wickelmaschine angeordnet.A swiveling inspection platform 18 is arranged next to the winding machine for manual fastening of the newly formed path start to the new winding tubes 16, 17.

Das Einlegen neuer Wickelhülsen 15, 16 und das Durchtrennen der Materialbahn 4 mit einer erfindungsgemäßen Vorrichtung wird im folgenden anhand der Fig. 1-5 näher erläutert:
Fig. 1 zeigt die Ladeposition, in der Hülsen 16 mit geringem Durchmesser oder Hülsen 17 mit großem Durchmesser manuell oder automatisch in die Hülsenrinne 9 eingelegt werden. Die Einschwenkarme 5 sind in dieser Position etwa um 45 Grad nach unten geneigt und die Schwenkarme 6 stehen in etwa senkrecht, was durch vollständiges Ausfahren der Zylinder der Kolben-Zylinder-Einheit 7 bewirkt wurde. Die fertig gewickelten Rollen sind aus dem Wickelbett 3 ausgestoßen. Sie liegen auf einer nicht dargestellten, halb abgesenkten Absenkbühne. Die Materialbahn 4 ist noch nicht durchgetrennt. Sie verbindet daher die fertigen Rollen mit der Vorratsrolle, wobei die Bahn 4 unter Spannung steht. Die Schneide des axial beweglichen Trennmessers 11 steht in Ruhestellung außerhalb des Bereichs der Materialbahn 4, und die Begehungsplattform 18 ist senkrecht gestellt.The insertion of new winding tubes 15, 16 and the cutting of the material web 4 with a device according to the invention is explained in more detail below with reference to FIGS. 1-5:
1 shows the loading position in which sleeves 16 with a small diameter or sleeves 17 with a large diameter are inserted manually or automatically into the sleeve groove 9. In this position, the pivoting arms 5 are inclined downward by approximately 45 degrees and the pivoting arms 6 are approximately vertical, which was brought about by completely extending the cylinders of the piston-cylinder unit 7. The completely wound rolls are ejected from the winding bed 3. They are on a half-lowered lowering platform, not shown. The material web 4 is not yet severed. It therefore connects the finished rolls to the supply roll, the web 4 being under tension. The cutting edge of the axially movable cutting knife 11 is in the rest position outside the area of the material web 4, and the inspection platform 18 is placed vertically.

Nach dem Einlegen der Hülsen 16 bzw. 17 in die Hülsenrinne 9 werden zunächst die Schwenkarme 6 mittels der Kolben-Zylinder-Einheit 7 in Richtung der Einschwenkarme 5 geschwenkt. Diese Schwenkbewegung wird durch die Anschläge 8 begrenzt. Bei Hülsen 17 mit großem Durchmesser ist diese Schwenkbewegung minimal, bei Hülsen 16 mit kleinem Durchmesser ist der Schwenkweg großer (Fig. 3).After the sleeves 16 and 17 have been inserted into the sleeve groove 9, the swivel arms 6 are first swiveled in the direction of the swivel arms 5 by means of the piston-cylinder unit 7. This pivoting movement is limited by the stops 8. With sleeves 17 with a large diameter, this swiveling movement is minimal, with sleeves 16 with a small diameter, the swivel path is longer (FIG. 3).

Anschließend werden die Einschwenkarme 5 mittels der Antriebseinrichtung 12 - 15 um die Achse der Tragwalze 2 gegen den Uhrzeigersinn, also in Richtung des Walzenbetts 3, geschwenkt. Zu Beginn der Schwenkbewegung rollen die Rollen 16 bzw. 17 über die Neigung der Hülsenrinne 9 gegen die Tragwalze 2, wobei sie von dem der Tragwalze 2 benachbarten Teil der Hülsenrinne 9 mitgeführt werden. Nachdem das Führungsrohr die Materialbahn 4 erreicht hat, beginnt es, diese mit zunehmender Schwenkbewegung in Richtung der Tragwalze 1 zu drücken und schafft so Platz zwischen der Materialbahn 4 und der Tragwalze 2, so daß die Hülsen 16 bzw. 17 immer weiter in Richtung des Walzenbetts 3 rollen können, bis sie das Walzenbett 3 erreicht haben, also auf beiden Tragwalzen 1, 2 aufliegen. In dieser Position wird die Einschwenkbewegung abgestoppt (Fig. 2, 4). Das Trennmesser 11 wird anschließend quer zur Materialbahn 4 über die gesamte Breite gefahren, wobei die gespannte Bahn 4 durchgetrennt wird. Wie aus den Fig. 2 und 4 ersichtlich ist, wird die Länge des so neugeschaffenen freien Bahnanfangs a bzw. b durch den vorher eingestellten Winkel zwischen den Einschwenkarmen 5 und den Schwenkarmen 6 bestimmt. Bei Hülsen 17 mit großem Durchmesser (Figur 2) ist der Abstand a zwischen der Schneidposition des Trennmessers 11 und der Berührungslinie der Wickelhülse 17 im Walzenbett 13 großer als die entsprechende Länge b bei Hülsen 16 mit geringem Durchmesser (Fig. 4).The pivoting arms 5 are then pivoted counterclockwise about the axis of the support roller 2 by means of the drive device 12-15, that is to say in the direction of the roller bed 3. At the beginning of the pivoting movement, the rollers 16 and 17 roll over the inclination of the sleeve trough 9 against the support roller 2, whereby they are carried along by the part of the sleeve trough 9 adjacent to the support roller 2. After the guide tube has reached the material web 4, it begins to press it with increasing pivoting movement in the direction of the support roller 1 and thus creates space between the material web 4 and the support roller 2, so that the sleeves 16 and 17 respectively can roll further and further in the direction of the roller bed 3 until they have reached the roller bed 3, that is to say they rest on both support rollers 1, 2. The pivoting movement is stopped in this position (FIGS. 2, 4). The cutting knife 11 is then moved across the entire width across the material web 4, the tensioned web 4 being severed. As can be seen from FIGS. 2 and 4, the length of the newly created free path start a or b is determined by the previously set angle between the swivel arms 5 and the swivel arms 6. In the case of sleeves 17 with a large diameter (FIG. 2), the distance a between the cutting position of the cutting knife 11 and the line of contact of the winding sleeve 17 in the roller bed 13 is greater than the corresponding length b for sleeves 16 with a small diameter (FIG. 4).

Nach dem Durchtrennen der Materialbahn 4 wird die komplette Vorrichtung - wie in Fig. 5 gezeigt - in eine untere Parkposition zurückgeschwenkt. Anschließend wird die schwenkbare Begehungsplattform 18 in eine waagerechte Stellung geklappt, so daß das Bedienungspersonal sie betreten kann, um den neugeschaffenen Anfang der Materialbahn 4 an dem Hülsensatz zu befestigen. Diese Befestigung ist problemlos, da ein auf den jeweiligen Hülsendurchmesser angepaßte freier Bahnanfang geschaffen wurde.After severing the material web 4, the complete device - as shown in FIG. 5 - is pivoted back into a lower parking position. The swiveling inspection platform 18 is then folded into a horizontal position so that the operating personnel can enter it in order to fasten the newly created start of the material web 4 to the sleeve set. This attachment is problem-free since a free path start adapted to the respective sleeve diameter has been created.

Nach dem anschließenden Starten der Wickelmaschine wird die Begehungsplattform 18 wieder senkrecht geklappt und danach die Hülseneinlegevorrichtung wieder in die Ausgangsposition nach Fig. 1 zur Aufnahme eines neuen Hülsensatzes geschwenkt.After the subsequent start of the winding machine, the inspection platform 18 is again folded vertically and then the tube insertion device is pivoted back into the starting position according to FIG. 1 for receiving a new tube set.
