Description

Die Erfindung betrifft eine Vorrichtung zum Rollenwechsel und Querschneiden für Mehrfachwickelmaschinen von Warenbahnen, mit mindestens zwei Wickelstellen, deren Zentrum auf einem gemeinsamen Schwenkkreis um den Mittelpunkt des Wickelstellenhalters angeordnet ist, fernermiteinem mindestens eine Umlenkwalze aufweisenden Halter, derfür ein Umlenken der zulaufenden Warenbahn um die leere Wickelhülse ausgebildet ist, ferner mit einem Querschneider zum Abtrennen der Warenbahn an einer Schnittstelle hinter der Wickelhülse und vor der Umlenkwalze sowie mit einer Andruckwalze zum Andrükken der zulaufenden Warenbahn an die Wickelhülse.The invention relates to a device for reel changing and cross cutting for multiple winding machines of webs, with at least two winding stations, the center of which is arranged on a common swiveling circle around the center of the winding station holder, furthermore with a holder having at least one deflecting roller, which is used for deflecting the incoming material web around the empty winding tube is further designed with a cross cutter for severing the web at an interface behind the winding tube and in front of the deflection roller and with a pressure roller for pressing the incoming web against the winding tube.

Vorrichtungen dieser Art sind in unterschiedlichen Ausführungen bekannt (z.B. DE-A-2 534 588; DD-A-90 466). Beim Aufwickeln von kontinuierlich und schnell zugeführten Warenbahnen zu einer Mehrfachwickelmaschine kommt es darauf an, die laufende Warenbahn möglichst schnell von der fertig gewickelten Rolle auf die leere Wickelhülse umzulegen und nach dem Abtrennen der Warenbahn den neuen Bahnanfang möglichst faltenfrei auf die leere Wickethülse anzulegen.Devices of this type are known in different designs (e.g. DE-A-2 534 588; DD-A-90 466). When winding continuously and quickly fed webs into a multiple winding machine, it is important to transfer the running web from the finished wound roll to the empty winding tube as quickly as possible and, after separating the web, to lay the new web start on the empty winding tube as wrinkle-free as possible.

Der Umstellungsprozess soll ohne Unterbrechung der Produktion möglich sein. Hierbei ist es bisher erforderlich, die Warenbahn in Abhängigkeit von ihren Eigenschaften auf jeweils einen bestimmten Wickelhülsendurchmesser aufzuwickeln und sämtliche Teile der Wechselvorrichtung und Quertrenneinrichtung auf den entsprechenden, gleichbleibenden Wickelhülsendurchmesser abzustimmen. Die bekannten Vorrichtungen erlauben einen schnellen Rollenwechsel deshalb nur, solange Material mit gleichen Eigenschaften auf Wickelhülsen gleichen Durchmessers gewickelt wird.The changeover process should be possible without interrupting production. It has so far been necessary to wind up the web depending on its properties on a particular winding tube diameter and to match all parts of the changing device and cross-cutting device to the corresponding, constant winding tube diameter. The known devices therefore allow a quick reel change only as long as material with the same properties is wound on winding cores of the same diameter.

Bei einer Änderung des Wickelhülsendurchmessers, wie er beispielsweise wegen geänderter Materialeigenschaften erforderlich sein kann, sind zeitaufwendige Justierarbeiten an der Wechselvorrichtung erforderlich. Es wird angestrebt, den Anfang der abgetrennten Warenbahnen bei der Umschlingung um die leere Wickelhülse als Zipfel zum faltenfreien Anlegen so kurz wie möglich zu halten. Bei Umstellung auf einen anderen Wickelhülsendurchmesser muss daher entweder die Produktion unterbrochen werden oder es müssen unfallträchtige und risikoreiche Einrichtarbeiten durchgeführt werden, um die Lage des Quertrennmessers, die Umlenkwalze für die die leere Wickelhülse umschlingende Warenbahn, die Stellung der Wickelhülse im Wickelstellenhalter und bei Bedarf auch den Gegenhalter auf die neuen Verhältnisse abzustimmen.In the event of a change in the winding tube diameter, as may be necessary, for example, because of changed material properties, time-consuming adjustment work on the changing device is required. The aim is to keep the beginning of the separated webs as short as possible when wrapping them around the empty winding tube as a tip for crease-free application. When changing to a different winding tube diameter, therefore, either the production must be interrupted or accidental and risky setup work must be carried out to determine the position of the cross cutting knife, the deflection roller for the web wrapping around the empty winding tube, the position of the winding tube in the winding position holder and, if necessary, also Adjust counterholders to the new conditions.

Diese komplizierten Justierarbeiten sind nicht nur zeitaufwendig und kostspielig, sie erfordern auch hochqualifizierte Fachleute an den Produktionsanlagen, damit eine optimale Einstellung überhaupt erreicht werden kann.These complicated adjustments are not only time-consuming and costly, they also require highly qualified specialists on the production systems so that an optimal setting can be achieved at all.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der als bekannt vorausgesetzten Art so auszubilden, dass sie einen Wechsel von Wickelhülsen unterschiedlichen Durchmessers ohne Umstellarbeiten und ohne Unterbrechung des Warenbahnzulaufs ermöglicht.The invention is based on the object of designing a device of the type known as ar t such that it enables a change of winding cores of different diameters without changeover work and without interrupting the web feed.

Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Kennzeichnungsteils von Anspruch 1.This object is achieved with the features of the labeling part of claim 1.

Bei der erfindungsgemässen Konstruktion bleibt der Mittelpunkt der Hülsen - unabhängig von der Art der Aufnahme - auch bei unterschiedlichen Durchmessern stets auf dem Schwenkkreis. In Abhängigkeit von dem Durchmesser erfolgt lediglich eine Verlagerung des Mittelpunkts um die halbe Differenz der Durchmesser zwischen der kleinsten Hülse und der davon abweichenden Hülse. Es fällt also bei den Wickelhülsen aller Durchmesser die Schnittgerade zwischen dem Schwenkkreis und den Umfangsflächen der Leerhülsen stets gleich. Die Schnittstelle liegt unmittelbar im Bereich des Schwenkkreises in unmittelbarer Nähe der Schnittgeraden zwischen Schwenkkreis und Umfangsfläche der Leerhülsen.In the construction according to the invention, the center of the sleeves - regardless of the type of receptacle - always remains on the swivel circle, even with different diameters. Depending on the diameter, the center point is only shifted by half the difference in diameter between the smallest sleeve and the sleeve deviating therefrom. In the case of winding cores of all diameters, the line of intersection between the swivel circle and the peripheral surfaces of the empty cores is always the same. The interface lies directly in the area of the swivel circle in the immediate vicinity of the intersection line between the swivel circle and the peripheral surface of the empty sleeves.

Es ist deshalb möglich, die Lage der Schneideinrichtung gegenüber der bei allen Hülsendurchmessern gleichen Schnittsgeraden zwischen Schwenkkreis und Umfangsfläche stets unverändert zu lassen und auch beim Einsatz unterschiedlicher Wickelhülsendurchmesser auf jegliche Einstellarbeiten zu verzichten. Es ist sehr einfach möglich, die Lage des Mittelpunkts der unterschiedlichen Wickelhülsen stets so einzustellen, dass bei allen unterschiedlichen Wickelhülsen die Schnittgerade zwischen Schwenkkreis und Umfangsfläche stets gleich bleibt. Dies kann beispielsweise programmgesteuert erfolgen, es ist aber auch möglich, die Lage der leeren Wickelhülsen abzutasten und danach die Verschwenkung des Wickelstellenhalters gegenüber der Ausgangslage vorzunehmen.It is therefore possible to always leave the position of the cutting device unchanged with respect to the line of intersection between the swivel circle and the circumferential surface that is the same for all core diameters, and to dispense with any adjustment work even when using different winding core diameters. It is very easily possible to always adjust the position of the center of the different winding cores in such a way that the intersection line between the swivel circle and the peripheral surface always remains the same for all different winding cores. This can be done, for example, in a program-controlled manner, but it is also possible to scan the position of the empty winding cores and then to pivot the winding point holder relative to the starting position.

Bei der erfindungsgemässen Vorrichtung entfallen sämtliche Justierarbeiten. Die Zahl der Bauteile wird verringert, da früher erforderliche zahlreiche Justieranschläge, die den unterschiedlichen Wickelhülsendurchmessern entsprechen, völlig fortfallen. Auch das grosse Unfallrisiko entfällt.In the device according to the invention, all adjustment work is omitted. The number of components is reduced because previously numerous adjustment stops, which correspond to the different winding tube diameters, are completely eliminated. The great risk of accidents is also eliminated.

Die Mehrfachwickelvorrichtung ist insgesamt mit 1 bezeichnet. Sie besitzt zwei schwenkbar auf einem nicht näher dargestellten Wickelstellenhalter angeordnete Wickelstellen 2 und 3. Die Zentren der Wickelstellen 2 und 3 liegen auf einem gemeinsamen Schwenkkreis 4, dessen Mittelpunkt 1a den Drehpunkt des Wickelstellenhalters darstellt.The multiple winding device is generally designated 1. It has two winding stations 2 and 3 arranged pivotably on a winding station holder, not shown. The centers of the winding stations 2 and 3 lie on a common swiveling circle 4, the center 1a of which represents the pivot point of the winding station holder.

Eine Wechseleinrichtung ist mit 5 bezeichnet und besitzt zwei Umlenkwalzen 6 und 7 sowie ein um den Drehpunkt der Umlenkwalze 7 schwenkbar angeordnetes Quertrennmessers 8 mit einem diesem zugeordneten Gegenhalter 9.A changing device is denoted by 5 and has two deflecting rollers 6 and 7 and a cross-cutting knife 8 pivotably arranged about the pivot point of the deflecting roller 7 with a counter-holder 9 assigned to it.

Bei der Wechseleinrichtung 5 ist ferner noch eine Andruckwalze 10 vorgesehen, deren Anpresskraft eingestellt werden kann.In the changing device 5, a pressure roller 10 is also provided, the pressing force of which can be adjusted.

Die Wickelstellen 2 und 3 sind geeignet, Wickelhülsen 11, 12, 13 und 14 unterschiedlichen Durchmessers aufzunehmen, und zwar wahlweise achslos oder mit Wickelwellen.The winding stations 2 and 3 are suitable for accommodating winding sleeves 11, 12, 13 and 14 of different diameters, either without an axle or with winding shafts.

Beim Wickelvorgang wird zunächst die Warenbahn 15 aus einer Produktionsmaschine kommend der Mehrfachwickelvorrichtung 1 über die Andruckwalze 10 zugeführt und an einer Wickelstelle 2 oder 3 aufgewickelt.During the winding process, the web 15 coming from a production machine is first fed to the multiple winding device 1 via the pressure roller 10 and wound up at a winding point 2 or 3.

Wenn der gewünschte Wickeldurchmesser erreicht ist, schwenkt die leere Wickelhülse 11, 12, 13 oder 14 zu einem allen Wickelhülsen gemeinsamen Haltepunkt, nämlich zur Schnittgeraden 16 zwischen Schwenkkreis 4 und Aussendurchmesser. Aus Fig. 2 ist ersichtlich, dass die Mittelpunkte 12a, 13a oder 14a der grösseren Wickelhülsen 12, 13 und 14 jeweils um die halbe Durchmesserdifferenz gegenüber dem Durchmesser der Wickelhülse 11 versetzt sind. Die Arretierung des Wickelstellenhalters in der dem jeweiligen Durchmesser entsprechenden Position kann in unterschiedlicher Weise gesteuert werden, beispielsweise mittels eines nicht dargestellten Grenzschalters, einer Fotozelle oder eines Prozessrechners.When the desired winding diameter is reached, the empty winding tube 11, 12, 13 or 14 pivots to a stop point common to all the winding tubes, namely to the straight line 16 between the swivel circle 4 and the outside diameter. It can be seen from FIG. 2 that the center points 12a, 13a or 14a of the larger winding tubes 12, 13 and 14 are each offset by half the diameter difference from the diameter of the winding tube 11. The locking of the winding point holder in the position corresponding to the respective diameter can be controlled in different ways, for example by means of a limit switch (not shown), a photo cell or a process computer.

Nachdem die leere Wickelhülse 11, 12, 13 oder 14 in die vorgesehene Position geschwenkt ist, erfolgt ein Einschwenken der Wechseleinrichtung 5, die mittels der Umlenkwalzen 6 und 7 die leere Wickelhülse 11, 12, 13 oder 14 umschlingt.After the empty winding tube 11, 12, 13 or 14 is pivoted into the intended position, the changing device 5 is swiveled in, which wraps around the empty winding tube 11, 12, 13 or 14 by means of the deflecting rollers 6 and 7.

Der Gegenhalter 9 wird zwischen der Andruckwalze 10 und der laufenden Warenbahn 15 zur Umlenkwalze 7 zugestellt. Zum Trennen der Warenbahn 15 schlägt das Quertrennmesser 8 auf die laufende Warenbahn 15 an einer Schnittstelle zwischen der leeren Wickelhülsen 11, 12, 13 oder 14 und dem Gegenhalter 9 bis vor die Andruckwalze 10. Der Warenbahnrest wird weiterhin der Wickelstelle 3 zugeführt, während der neue Bahnanfang als Zipfel 17 zwischen der Andruckwalze 10 und der Wickelhülse 11, 12, 13 oder 14 geführt und aufgewickelt wird.The counterholder 9 is fed between the pressure roller 10 and the running web 15 to the deflection roller 7. To separate the web 15, the cross cutting knife 8 strikes the running web 15 at an interface between the empty winding sleeves 11, 12, 13 or 14 and the counter-holder 9 up to the pressure roller 10. The remainder of the web is still fed to the winding station 3 while the new one The beginning of the web as a tip 17 between the pressure roller 10 and the winding tube 11, 12, 13 or 14 is guided and wound up.

Um den Zipfel 17 bei hohen Bahngeschwindigkeiten und allen unterschiedlichen Durchmessern der Wickelhülsen 11,12,13 oder 14 für ein faltenfreies Anlegen an diese Wickelhülsen so kurz wie möglich zu halten, ist es wichtig, dass das Aufsetzen des Quertrennmessers 8 auf die Warenbahn an einer Stelle annähernd auf dem Schwenkkreis 4 oder innerhalb des Schwenkkreises 4 erfolgt.In order to keep the tip 17 as short as possible at high web speeds and all different diameters of the winding tubes 11, 12, 13 or 14 for a wrinkle-free application to these winding tubes, it is important that the cross cutting knife 8 is placed on the web at one point approximately on the swivel circle 4 or within the swivel circle 4.

Bei der Ausführungsform gemäss Fig. 2 ist die Warenbahn 15 durch das Quertrennmesser 8 getrennt und der Anfang der nachfolgenden Wartenbahn als Zipfel 17 an die Wickelhülse angelegt. Eine Bürste oder ein Luftstrahl kann der Warenbahn 15 als Anlagehilfe 18 dienen.In the embodiment according to FIG. 2, the web 15 is separated by the cross-cutting knife 8 and the beginning of the subsequent waiting web is applied to the winding tube as a tip 17. A brush or an air jet can serve the web 15 as an investment aid 18.

Die Schnittgerade aller unterschiedlichen Hülsen 11, 12, 13 und 14 ist so gewählt, dass das Aufsetzen des Quertrennmessers auf die Warenbahn 15 bei der kleinsten Wickelhülse 11 nahezu auf dem Schwenkkreis 4 und bei den Wickelhülsen 11, 12, 13 und 14 innerhalb des Schwenkkreises 4 erfolgt. Die auslaufende Warenbahn 15 von allen Wickelhülsen 11, 12, 13 und 14 zu der Umlenkwalze 7 bildet bei unveränderter Position und Bewegung des Quertrennmessers bis zu deren Trennpunkt kurze Zipfel 17, die faltenfrei und ohne Umschlag zwischen die Andruckwalze 10 geführt werden.The intersection line of all different sleeves 11, 12, 13 and 14 is selected so that the cross cutting knife is placed on the web 15 with the smallest winding sleeve 11 almost on the swivel circle 4 and with the winding sleeves 11, 12, 13 and 14 within the swivel circle 4 he follows. The outgoing web 15 from all the winding tubes 11, 12, 13 and 14 to the deflection roller 7 forms with unchanged position and movement of the cross-cutting knife up to its separation point short lobes 17, which are wrinkle-free and without an envelope between the pressure roller 10.

Bei der Ausführungsform gemäss Fig. 3 ist wegen eines anderen Drehpunkts die Schwenkrichtung des Quertrennmessers 8' verändert. Auch hier erfolgt das Aufsetzen des Quertrennmessers auf die auslaufende Warenbahn in der gleichen Weise wie bei der ersten Ausführungsform entweder auf dem Schwenkkreis oder innerhalb des Schwenkkreises.In the embodiment according to FIG. 3, the pivoting direction of the cross cutting knife 8 'is changed because of another pivot point. Here too, the cross cutting knife is placed on the outgoing web in the same way as in the first embodiment either on the swivel circle or within the swivel circle.

Im Ausführungsbeispiel gemäss Fig. 4 ist das Quertrennmesser 8" als Sichel- oder Hakenmesser ausgebildet und an einen Führungsschlitten 19 quer über die Wickelhülsen 11, 12, 13 und 14 geführt. Auch hier liegt die Schnittstelle auf dem Schwenkkreis oder innerhalb des Schwenkkreises 4.4, the cross cutting knife 8 "is designed as a sickle or hook knife and is guided on a guide carriage 19 across the winding sleeves 11, 12, 13 and 14. The interface is also on the swivel circle or within the swivel circle 4.

Bei der Ausführungsform 5 ist es möglich, mit einem begrenzt schwenkbaren Quertrennmesser 8"', das in einem Führungsschlitten 19 quer zur Warenbahn 15 geführt ist, im Bereich der Schnittgeraden 16 zu trennen. Damit ein Trennen der Warenbahn 15 mittels des Quertrennmessers 8"' nahezu auf dem Schwenkkreis4füralleWickelhülsen 11, 12, 13und 14 möglich ist, wird die Warenbahn 15 mittels einer verschwenkbaren Umlenkwalze 20 so weit um die leere Wickelhülse herumgeführt, dass sie erst am Schwenkkreis 4 oder ausserhalb des Schwenkkreises 4 von der leeren Wickelhülse abläuft.In embodiment 5, it is possible to cut in the region of the intersecting straight line 16 with a limited pivoting cross cutting knife 8 "', which is guided in a guide carriage 19 transversely to the web 15. In this way, the web 15 is almost separated by means of the cross cutting knife 8"' on the swivel circle 4 for all winding sleeves 11, 12, 13 and 14 is possible, the material web 15 is guided so far around the empty winding tube by means of a pivotable deflecting roller 20 that it does not run off the empty winding tube until the swivel circle 4 or outside of the swivel circle 4.
