Abstract

The winding machine of the invention includes two parallel wound web roll support rollers which are spaced apart and on which the roll being wound is supported. The gap between the support rollers and below the supported wound roll is to be pressurized. A pressure chamber is defined by the support rollers, the wound roll above, and from below by a cross member which bridges over the distance between the support rollers and closes the bottom of the gap. End walls close the ends of the chamber. The cross member is movable between a sealing position where it is in contact with, or at least is sealed with, the two support rollers and bridges the gap between them to an open position where it opens the gap between the support rollers. The cross member is movable either down out of the gap, laterally out of the gap, or a combination of both, by reciprocating swinging, or oblique movement, and the like. The cross member has at least one passage which connects the pressure chamber with a source of compressed air through an intermediate conduit. An elongate transverse distributing pipe arranged at a distance from the cross member has a pressure connection through the conduit leading to the cross member.

Description

Die Erfindung betrifft eine Wickelmaschine zum Aufwickeln einer laufenden Papierbahn.The invention relates to a winding machine for winding a running one Paper web.

Es sind zahlreiche Bauarten derartiger Maschinen bekanntgeworden. Es wird auf EP 0 496 863 B1 verwiesen. Dabei handelt es sich um eine Doppeltragwalzen-Wickelmaschine mit der Möglichkeit der Druckluftentlastung des Gewichtes der entstehenden Papierrollen. Zu diesem Zweck ist ein Druckraum gebildet, der durch die folgenden Elemente begrenzt ist: durch die Mantelflächen der beiden Tragwalzen; durch die Mantelfläche der entstehenden Papierrolle selbst; durch jeweils eine verschiebbare Stirnwand, die sich jeweils in einem Endbereich der Tragwalzen befindet, sowie durch einen Blaskasten, der sich parallel zu den Tragwalzen erstreckt und an den Mantelflächen der Tragwalzen mehr oder minder dichtend anliegt. Der Blaskasten ist von den Tragwalzen hinwegbewegbar, beispielsweise um Papierreste nach einem Papierstau zu entfernen, oder um bei einem Rollenwechsel ein Trennmesser von unten her in den Spalt zwischen den Tragwalzen einzuschwenken.Numerous types of such machines have become known. It will refer to EP 0 496 863 B1. It is a Double carrier roller winding machine with the possibility of compressed air relief the weight of the resulting paper rolls. For this purpose is a Pressure space formed, which is limited by the following elements: by the Lateral surfaces of the two support rollers; through the lateral surface of the emerging paper roll itself; each with a sliding end wall, which is located in an end region of the support rollers, as well as by a blow box that extends parallel to the support rollers and to the Shell surfaces of the support rollers are more or less sealing. The Blow box can be moved away from the support rollers, for example by To remove paper scraps after a paper jam, or to remove one Reel a cutting knife from below into the gap between the Swing in support rollers.

Eine Maschine gemäß diesem Dokument vermag zwar durch den Überdruck im Druckraum eine Kompensation des Eigengewichtes der Papierrolle(n) zu erzielen. Jedoch ist dies mit gravierenden Nachteilen verbunden.A machine in accordance with this document is capable of overpressure in the printing room to compensate for the weight of the paper roll (s) achieve. However, this is associated with serious disadvantages.

So erfordert der Blaskasten als solcher relativ viel Raum, da er sich im allgemeinen bis unter die unteren Scheitelpunkte der beiden Tragwalzen erstreckt. Wird der Blaskasten von den beiden Tragwalzen hinwegbewegt, so wird hierzu ebenfalls Raum benötigt. Da der Blaskasten meist nur nach unten weggefahren werden kann, und da eine hierzu erforderliche Hubeinrichtung in der Regel an der Unterseite des Blaskastens angreift, muß entsprechend viel Raum unter der Maschine bereitgestellt werden. Gerade dort fehlt es aber häufig an Raum.The blow box as such requires a relatively large amount of space because it is located in the general to below the lower vertices of the two support rollers extends. If the blow box is moved away from the two support rollers, so space is also required for this. Since the blow box mostly only downwards can be moved away, and since a necessary lifting device in usually attacks at the bottom of the blow box, must accordingly Space must be provided under the machine. But it is precisely there that is missing often in space.

DE 42 19 541 A1 beschreibt eine Wickelmaschine mit einem Blaskasten. Mit dem Blaskasten fest verbunden ist eine Tülle, die in den keilförmigen Zwickel zwischen den beiden Tragwalzen einfahrbar ist. Der komplette Blaskasten muß dabei diese Bewegung ausführen. Dies ist außerordentlich umständlich.DE 42 19 541 A1 describes a winding machine with a blow box. With the blow box is firmly connected to a spout that is in the wedge-shaped gusset is retractable between the two support rollers. The complete blow box must perform this movement. This is extremely cumbersome.

US-PS-3 497 151 beschreibt eine Wickelmaschine mit zwei Tragwalzen. Im keilförmigen Einlaufspalt zwischen den beiden Tragwalzen ist ein Blaskasten fest eingebaut. Dies ist deshalb nachteilig, weil sich bei Abrissen der Papierbahn der dann auftretende Papierstau schwer zu entfernen ist.US-PS-3 497 151 describes a winding machine with two support rollers. in the wedge-shaped inlet gap between the two support rollers is a blow box permanently installed. This is disadvantageous because the demolition of the Paper web the paper jam then occurring is difficult to remove.

Die Zeitschrift "Das Papier" zeigt in Heft 8, 1993, auf Seite 522 eine Wickelmaschine mit zwei Tragwalzen. In den keilförmigen Einlaufspalt ist ein Blaskasten ein- und ausfahrbar. Der Blaskasten sowie der dazugehörende Betätigungsmechanismus haben einen erheblichen baulichen Umfang. Dies führt zu Problemen, weil in der Regel nicht genügend Bauraum zur Verfügung steht.The magazine "Das Papier" shows in issue 8, 1993, on page 522 one Winding machine with two support rollers. In the wedge-shaped inlet gap is a Blow box retractable and extendable. The blow box and the corresponding one Actuation mechanism have a considerable structural scope. This leads to problems because usually there is not enough space available stands.

DE-AS 1 047 001 zeigt eine Wickelmaschine mit zwei Tragwalzen sowie mit einem Blaskasten mit zugehörender Tülle. Beide Bauteile, Blaskasten und Tülle sind voluminös, so daß auch hier wiederum Probleme beim Abriß der Papierbahn entstehen.DE-AS 1 047 001 shows a winding machine with two support rollers and with a blow box with associated grommet. Both components, blow box and Spouts are voluminous, so that here again problems with the demolition Paper web arise.

EP 0 631 955 A2 beschreibt eine Wickelmaschine mit Blaskasten. Der Blasksten ist zwar aus dem Einlaßbereich zwischen den beiden Tragwalzen herausschwenkbar. Er ist jedoch äußerst voluminös, so daß es auch hier aufgrund des begrenzten Raumes Probleme gibt.EP 0 631 955 A2 describes a winding machine with a blow box. The Blow box is from the inlet area between the two support rollers swung out. However, it is extremely voluminous, so it is here too problems due to the limited space.

Die WO 96/07608 offenbart eine Wiekelmaschine gemäß dem jeweiligen Oberbegriff der Ansprüche 1, 2 und 7. WO 96/07608 discloses a weighing machine according to the respective preamble of claims 1, 2 and 7.

Der Erfindung liegt die Aufgabe zugrunde, eine Tragwalzen-Wickelmaschine gemäß dem jeweiligen Oberbegriff der Ansprüche 1, 2 und 7 derart zu gestalten, daß unterhalb der Tragwalzen weniger Raum als seither beansprucht wird, und daß die Druckentlastungsvorrichtung einfacher und billiger als bisher gestaltet wird.The invention has for its object a support roller winding machine to design according to the respective preamble of claims 1, 2 and 7 such that below the support rollers less space than has been used since, and that the Pressure relief device is made easier and cheaper than before.

Diese Aufgabe werden durch die Merkmale der Ansprüche 1, 2 und 7 gelöst.This object is solved by the features of claims 1, 2 and 7.

Bevozugte Ausführungsformen sind in dem abhängigen Ansprüchen offenbart.Preferred embodiments are disclosed in the dependent claims.

Die Erfinder sind bei der Lösung des Problemes einen Weg gegangen, der sich von EP 0 496 863 B1 grundlegend unterscheidet. Statt des dort vorgesehenen Blaskastens verwenden sie zum Überbrücken des Abstandes zwischen den beiden Tragwalzen und damit zum Begrenzen eines Druckraumes eine Traverse. Weiterhin führen sie Druckluft über eine Leitung oder (abhängig von der Bahnbreite) über eine Mehrzahl von über die Bahnbreite verteilten Leitungen durch die Traverse hindurch in den Druckraum ein.The inventors have followed a path in solving the problem that differs fundamentally from EP 0 496 863 B1. Instead of that there Use the provided blow box to bridge the distance between the two support rollers and thus to limit one Pressure chamber a traverse. They also carry compressed air through a line or (depending on the web width) over a plurality of over the Distribution of web width lines through the traverse into the pressure chamber on.

Die Traverse hat, verglichen mit dem bisherigen Blaskasten, einen viel kleineren Querschnitt, in einer zu den Tragwalzenachsen senkrechten Schnittebene gesehen. Im Extremfall besteht die Traverse lediglich aus einer Platte, die mit ihren beiden Längskanten jeweils eine Dichtung mit den betreffenden Tragwalzenmänteln bildet. Es kommt daher nicht zu Raumproblemen beim Abfahren der Traverse, und zwar auch dann nicht, wenn diese nach unten abgefahren wird. Dabei ist besonders hilfreich, daß die Hubeinrichtung weiter oben als bisher angreifen kann. Die Traverse kann auch nach einer Seite herausgefahren werden, d.h. parallel zu den Tragwalzenachsen, oder gar senkrecht zu diesen unter einer der beiden Tragwalzen hinweg in horizontaler Richtung. Auch ein Wegschwenken ist denkbar, wobei die Traverse an der Mantelfläche einer der Tragwalzen anliegen bleiben kann, also um eine zur Tragwalze parallele Achse schwenkt. Jedoch kann auch eine exzentrische Schwenkachse vorgesehen werden. The traverse has a lot compared to the previous blow box smaller cross-section, in a perpendicular to the support roller axes Sectional plane seen. In the extreme case, the traverse consists of only one Plate with a seal with the two longitudinal edges relevant roller shells. It is therefore not the case Space problems when moving the traverse, and not even then, when it is moved down. It is particularly helpful that can attack the lifting device further up than before. The traverse can can also be moved out to one side, i.e. parallel to the Carrier roller axes, or even perpendicular to these under one of the two Carrier rollers away in the horizontal direction. Swinging away is also conceivable, the traverse on the lateral surface of one of the support rollers can remain in contact, i.e. pivots about an axis parallel to the support roller. However, an eccentric pivot axis can also be provided.

Insbesondere bei Wickelmaschinen für große Bahnbreiten kann zwar auch bei der erfindungsgemäßen Maschine ein Luftdruckkasten vorgesehen werden. Dieser wird dann jedoch von der Traverse entfernt angeordnet, beispielsweise unterhalb einer der beiden Tragwalzen. Eine Mehrzahl von Leitungen stellt eine Verbindung her zwischen diesem Druckkasten und dem Druckraum zwischen den Tragwalzen, der Traverse, der Papierrolle und den seitlichen verschiebbaren Stirnwänden. Der Druckluftkasten hat somit die Funktion eines Querverteilrohres, wobei dem Druckraum unter der Papierrolle eine entsprechende Anzahl von Druckluftströmen beispielsweise gleicher Drücke und Durchsätze zugeführt werden.In particular in the case of winding machines for large web widths it can also be used for an air pressure box can be provided for the machine according to the invention. However, this is then placed away from the traverse, for example below one of the two support rollers. A majority of Lines creates a connection between this pressure box and the Pressure space between the support rollers, the crossbeam, the paper roll and the side sliding end walls. The compressed air box therefore has that Function of a cross distribution pipe, the pressure chamber under the paper roll a corresponding number of compressed air flows, for example the same Pressures and throughputs are supplied.

Man könnte somit sagen, daß die Funktionen des bekannten Blaskastens gemäß dem genannten Dokument aufgeteilt sind auf zwei Komponenten: die eine Komponente ist die Traverse, die nunmehr lediglich noch die Funktion hat, den Druckraum unter der entstehenden Papierrolle abzusperren, und die andere Komponente ist das Querverteilrohr mit den Leitungen, welche gemeinsam die Funktion übernehmen, eine optimale Führung und Gestaltung der Druckluftströme zu bewirken.One could say that the functions of the known blow box according to the document mentioned are divided into two components: the one component is the traverse, which is now only the function has to shut off the print room under the emerging paper roll, and the another component is the cross distribution pipe with the lines, which together take on the function, optimal management and design of the compressed air flows.

Das Querverteilrohr kann stationär sein, jedoch ist dies nicht zwingend erforderlich. Die genannten Leitungen sind zweckmäßigerweise Schläuche.
Die einzelne Leitung kann teleskopierbar sein. Sie kann auch zusammengesetzt sein aus gelenkig miteinander verbundenen Abschnitten.
The cross distribution pipe can be stationary, but this is not absolutely necessary. The lines mentioned are expediently hoses.
The single line can be telescopic. It can also be composed of sections which are connected to one another in an articulated manner.

Ist das Querverteilrohr wenigstens annähernd so lang, wie die Arbeitsbreite der Maschine ist, und sind die einzelnen Leitungen, die das Querverteilrohr mit dem Druckraum verbinden, gleichmäßig über die Länge des Querverteilrohres angeordnet, so wird erreicht, daß die Druckverteilung über die Arbeitsbreite optimal ist.Is the cross distribution pipe at least approximately as long as the working width of the machine, and are the individual lines that make up the cross pipe Connect to the pressure chamber, evenly over the length of the Arranged cross-distribution pipe, it is achieved that the pressure distribution over the working width is optimal.

Die in Fig. 1 gezeigte Tragwalzen-Wickelmaschine umfaßt zwei Tragwalzen 1, 2. Diese dienen zum Aufwickeln einer fortlaufenden Papierbahn 3.1 zu einer Papierrolle 3.2.The support roller winding machine shown in Fig. 1 comprises two support rollers 1, 2. These are used to wind a continuous paper web 3.1 into one Paper roll 3.2.

Unterhalb der beiden Tragwalzen 1, 2 befindet sich der Maschinenkeller mit dem Kellerboden 4.The machine cellar is located below the two support rollers 1, 2 the basement floor 4.

Der gegenseitige Abstand zwischen den Mantelflächen der beiden Tragwalzen 1, 2 ist im dargestellten Beispiel durch eine Traverse 5 überbrückt. Wie man sieht, hat die Traverse 5 im wesentlichen die Gestalt eines umgekehrten L mit den beiden Schenkeln 5.1 und 5.2. The mutual distance between the lateral surfaces of the two support rollers 1, 2 is bridged by a cross member 5 in the example shown. How one see, the traverse 5 has essentially the shape of an inverted L with the two legs 5.1 and 5.2.

Man erkennt ferner ein Querverteilrohr 6 sowie eine Mehrzahl von Schläuchen 7, von denen nur ein einziger hier zu sehen ist.A transverse distribution pipe 6 and a plurality of hoses can also be seen 7 of which only one can be seen here.

Traverse 5 und Querverteilrohr 6 erstrecken sich im wesentlichen über die gesamte Arbeitsbreite der Maschine, zumindest über die Mindest-Arbeitsbreite. Sie sind damit wenigstens annähernd so lang wie die Papierrolle 3.2 bzw. die Gesamtheit der Papierrollen, falls eine Längsschneideinrichtung vorhanden ist. Das Querverteilrohr 6 weist eine der Anzahl der Schläuche 7 entsprechende Anzahl von Druckluftauslässen 6.1 auf, und der Schenkel 5.1 der Traverse 5 ist ebenfalls mit einer entsprechenden Anzahl von Durchlässen versehen, gebildet aus Druckluftstutzen 5.3. Wie man sieht, ist jeweils ein Ende eines jeden Schlauches 7 einerseits an einen Anschluß 6.1 des Querverteilrohres 6, und andererseits an einen Druckluftstutzen 5.3 des Schenkels 5.1 angeschlossen.Traverse 5 and transverse distribution pipe 6 extend essentially over the total working width of the machine, at least over the minimum working width. They are at least approximately as long as that Paper roll 3.2 or the entirety of the paper rolls, if one Longitudinal cutting device is available. The cross distribution pipe 6 has one of the Number of hoses 7 corresponding number of compressed air outlets 6.1 on, and the leg 5.1 of the cross member 5 is also with a appropriate number of passages, formed from Compressed air socket 5.3. As you can see, there is an end to each Hose 7 on the one hand to a connection 6.1 of the transverse distribution pipe 6, and on the other hand connected to a compressed air nozzle 5.3 of the leg 5.1.

Auf dem Kellerboden 4 ist eine Stuhlung 8 befestigt. Diese trägt ihrerseits das Querverteilrohr 6 sowie einen Schlitten 8.1. Schlitten 8.1 führt ein Gleitstück 5.4, das wiederum am senkrechten Schenkel 5.2 der Traverse 5 angreift. Bei einer Auf- und Ab-Bewegung der Traverse 5 ist somit eine tadellose vertikale Führung gewährleistetA chair 8 is attached to the basement floor 4. This in turn bears the Cross distribution pipe 6 and a slide 8.1. Carriage 8.1 guides a slider 5.4, which in turn acts on the vertical leg 5.2 of the cross member 5. at an up and down movement of the traverse 5 is thus an impeccable vertical Leadership guaranteed

Als Aktuator für eine Auf- und Ab-Bewegung der Traverse 5 dient ein Spindeloder ein Hydraulik- oder ein Pneumatik-Antrieb 9. Wie man sieht, sind Traverse 5 und Schläuche 7 in zwei Positionen dargestellt. In der oberen, ausgezogen dargestellten Position sperrt der horizontale Teil 5.1 der Traverse 5 den Druckraum 10 unterhalb der Papierrolle 3.2 ab. In der unteren, strichpunktiert dargestellten Position ist dies nicht der Fall.A spindle or serves as an actuator for an up and down movement of the traverse 5 a hydraulic or a pneumatic drive 9. As you can see, are Traverse 5 and hoses 7 shown in two positions. In the top, The position 5.1 shown in solid lines blocks the traverse 5 from the pressure chamber 10 below the paper roll 3.2. In the lower one, this is not the case.

Die Wickelmaschine gemäß Fig. 1 weist zusätzlich eine Bahntrennvorrichtung 11 auf. Diese ist in Richtung des Doppelpfeiles um die Achse der Tragwalze 2 verschwenkbar. Diese Trennvorrichtung wird dann in Aktion gesetzt, wenn die Papierrolle 3.2 ihren vollen Durchmesser erreicht, und wenn die Traverse 5 nach unten abgefahren ist. In diesem Falle gelangt die Schneide 11.1 der Trennvorrichtung 11 durch den Zwischenraum zwischen den beiden Tragwalzen 1, 2 nach oben.1 additionally has a web cutting device 11 on. This is in the direction of the double arrow around the axis of the support roller 2 pivotable. This separator is then put into action when the Paper roll 3.2 reaches its full diameter, and when the traverse 5 has gone down. In this case, the cutting edge 11.1 arrives Separating device 11 through the space between the two Carrier rollers 1, 2 upwards.

Es versteht sich, daß der Druckraum 10 wenigstens in gewissem Maße luftdicht sein muß, damit die Kompensationswirkung der Druckluftentlastungseinrichtung eintreten kann. Zu diesem Zwecke sind im Bereich der Längskanten des horizontalen Teiles 5.1 Dichtungen 12, 13 vorgesehen. Dabei kann es sich um Dichtleisten handeln. Es können aber auch Labyrinthdichtungen oder dgl. verwendet werden, so daß die Dichtung eine berührungsfreie ist.It is understood that the pressure chamber 10 at least to a certain extent must be airtight so that the compensation effect of the Compressed air relief device can occur. For this purpose Area of the longitudinal edges of the horizontal part 5.1 seals 12, 13 intended. These can be sealing strips. But it can labyrinth seals or the like can also be used, so that the seal is a non-contact.

Die Papierbahn 3.1 ist, wie man sieht, von links unten her an die Tragwalze 1 herangeführt und umschlingt diese somit von unten nach oben. Es wäre jedoch auch denkbar, diese von rechts oben an die zweite Tragwalze einzuführen und durch den Preßspalt zwischen der Tragwalze 2 und der Papierrolle 3.2 hindurchzuführen. Diese Bahnführung vermeidet die Gefahr, daß Luft aus dem Druckraum 10 zwischen die Papierlagen der Papierrolle 3.2 eingewickelt wird. Auch hätte Sie den Vorteil, daß keine der beiden Dichtungen 12, 13 berührungsfrei zu sein hätte. Vielmehr könnten zwischen den Längskanten des horizontalen Teiles 5.1 der Traverse 5 und den Mantelflächen der beiden Tragwalzen 1, 2 berührende Dichtungen vorgesehen werden. Die Trennvorrichtung 11 würde durch eine weiter unten beschriebene Perforiereinrichtung ersetzt werden.As can be seen, the paper web 3.1 is from the bottom left to the support roller 1 introduced and wraps around it from bottom to top. It would be but also conceivable, this from the top right to the second support roller introduce and through the nip between the support roller 2 and the Pass paper roll 3.2 through. This guideway avoids the risk that air from the pressure chamber 10 between the paper layers of the paper roll 3.2 is wrapped. You would also have the advantage that neither of the two Seals 12, 13 would have to be non-contact. Rather, between the longitudinal edges of the horizontal part 5.1 of the cross member 5 and the Shell surfaces of the two support rollers 1, 2 contact seals be provided. The separator 11 would be replaced by one below perforating device described are replaced.

Die Ausführungsform gemäß Fig. 2 unterscheidet sich von jener gemäß Fig. 1 vor allem durch die Art des Verfahrens der Traverse 5. Während bei Fig. 1 die Traverse vertikal auf- und abfahrbar ist, ist sie hier bei Fig. 2 schwenkbar - siehe die strichpunktiert dargestellte, abgeschwenkte Position. Das Querverteilrohr 6 befindet sich auf dem Kellerboden 4. Der pneumatische Aktuator 9 ist ebenfalls anders angeordnet als bei der Ausführungsform gemäß Fig. 1. Hierdurch ergeben sich bei der Anordnung gemäß Fig. 2 Vorteile bezüglich des Wegräumens von Papierausschuß, der von oben nach unten fallen könnte.The embodiment according to FIG. 2 differs from that according to FIG. 1 especially by the type of traverse 5. While in Fig. 1 the Traverse is vertically up and down, it can be pivoted here in Fig. 2 - see the swiveled position shown in broken lines. The Cross distribution pipe 6 is located on the basement floor 4. The pneumatic Actuator 9 is also arranged differently than in the embodiment 1. This results in the arrangement according to FIG. 2 Advantages of clearing paper waste from top to bottom could fall down.

Die Ausführungsform gemäß Fig. 3 ist ähnlich jener gemäß Fig. 2. Auch hier steht der Gedanke im Vordergrund, Papierstau schnell und leicht abführen zu können. Wie angedeutet, kann der Traversen-Querschnitt ein nach unten offenes U sein, z.B. aus Stabilitätsgründen.3 is similar to that of FIG. 2. Also here the main focus is on clearing paper jams quickly and easily can. As indicated, the truss cross section can be a down be open U, e.g. for reasons of stability.

Bei der Ausführungsform gemäß der Figuren 4.1 und 4.2 handelt es sich um eine Traverse 5, die ähnlich jener gemäß Fig. 1 gestaltet ist. Auch hier ist wiederum eine Schlittenführung 5.4, 8.1 vorgesehen, um eine einwandfreie Vertikalführung der Traverse 5 durch den pneumatischen Aktuator 9 zu erzielen. Wie man aus den beiden Figuren erkennt, sind den Druckluftstutzen 5.3 Abdeckkappen 5.5 zugeordnet. Diese haben einerseits eine Schutzfunktion, indem sie dafür sorgen, daß keine Verunreinigungen in die Schläuche 7 gelangen. Andererseits sorgen sie für eine weitere Vergleichmäßigung der Luftströme, da jeder Einzel-Luftstrom entsprechend den Pfeilen 5.6 geteilt und umgelenkt wird.The embodiment according to FIGS. 4.1 and 4.2 is a cross member 5, which is designed similar to that of FIG. 1. Here too in turn, a slide guide 5.4, 8.1 is provided to ensure a flawless Vertical guidance of the traverse 5 through the pneumatic actuator 9 achieve. As you can see from the two figures, the compressed air nozzle 5.3 Cover caps 5.5 assigned. On the one hand, these have one Protective function by ensuring that no impurities enter the Get hoses 7. On the other hand, they provide another one Uniformization of the air flows, since each individual air flow is corresponding the arrows 5.6 is divided and redirected.

Die Ausführungsform gemäß Fig. 5 ähnelt jener gemäß Fig. 2 bezüglich Anordnung und Aufhängung der Traverse 5 sowie bezüglich der Anordnungen des Querverteilrohres 6 und des pneumatischen Aktuators 9.The embodiment according to FIG. 5 is similar to that according to FIG. 2 with regard to Arrangement and suspension of the cross member 5 and in relation to the Arrangements of the cross distribution pipe 6 and the pneumatic actuator 9.

Die Traverse 5 hat hier zwar Kastenform. Jedoch dient diese lediglich zur Versteifung der Konstruktion, indem die Traverse 5 einen relativ großenTeil der Enden einer jeden Leitung 7 aufnimmt. Nur die außerhalb der Traverse 5 befindlichen Leitungsteile sind flexibel. The traverse 5 has a box shape here. However, this is only for Stiffening of the construction by the cross member 5 a relatively large part the ends of each line 7 receives. Only the outside of the traverse 5 existing pipe parts are flexible.

Eine weitere Variante wird weiter unten anhand der Fig. 9 beschrieben, im wesentlichen mit den folgenden Merkmalen:Another variant is described below with reference to FIG. 9, in essential with the following characteristics:

Die Traverse 5 trägt eine Bahntrennvorrichtung 11, die relativ zur Traverse beweglich und somit in herkömmlicher Weise von unten her vertikal in das Wickelbett einfahrbar ist, um beim Rollenwechsel die Bahn durchzutrennen.The crossbeam 5 carries a web cutting device 11 which is relative to the crossbeam movable and thus in a conventional manner from below vertically into the The changing bed can be retracted to cut the web when changing reels.

In einer weiteren Alternative hierzu kann man anstelle einer Bahntrennvorrichtung 11 gemäß den deutsches Patentanmeldungen 195 19 306.7 und 295 08 732.3 eine Perforiereinrichtung vorsehen, vorzugsweise in Kombination mit einer automatischen Bahnende-Verklebeeinrichtung. Dies hat z.B. gemäß Fig. 6 oder 8 den Vorteil, daß man bei der Gestaltung der Gewichtsentlastungseinrichtung keinerlei Rücksicht mehr nehmen muß auf eine herkömmliche Bahntrennvorrichtung; d.h., die Traverse muß weniger weit nach unten abschwenkbar sein, weil keine Kollisionsgefahr mit der Bahntrennvorrichtung mehr besteht; sie braucht auch nicht als Träger für eine Bahntrennvorrichtung zu dienen.In a further alternative, one can instead of one Web cutting device 11 according to German patent applications 195 19 306.7 and 295 08 732.3 provide a perforating device, preferably in combination with an automatic web end gluing device. This has e.g. according to Fig. 6 or 8 the advantage that when designing the Weight relief device no longer has to be considered a conventional web separator; i.e. the traverse must be less far be pivoted downwards because there is no risk of collision with the Web separator exists more; it also does not need to be a carrier for one Serve web cutting device.

Ferner ist folgendes denkbar:The following is also conceivable:

Die Traverse dient zugleich zur Abstützung einer Bahneinziehvorrichtung; diese muß aktiviert werden, wenn in der Abrollstation (von der die Papierbahn geliefert wird) ein Rollenwechsel stattfindet und somit ein neuer Bahnanfang in die Wickelmaschine eingefädelt werden muß. Siehe z.B. Fig. 7.The traverse also serves to support a web retractor; this must be activated if in the unwind station (from which the paper web a roll change takes place and thus a new beginning of the path in the winding machine has to be threaded. See e.g. Fig. 7.

Die Druckluftzufuhr über flexible Leitungen bietet die Möglichkeit, den Volumenstrom über die Maschinenbreite auf einfache Weise zu variieren, z. B. können in den Randzonen größere Leitungsquerschnitte vorgesehen werden, um eine eventuelle Leckage an den stirnseitigen Abdichtungen auszugleichen. The compressed air supply via flexible lines offers the possibility of Vary volume flow across the machine width in a simple manner, for. B. larger pipe cross-sections can be provided in the edge zones, to compensate for any leakage on the front seals.

Bei einer nach unten offenen Traverse können die Dichtleisten von der Innenseite der Traverse her angeschraubt werden. Die Verschraubungen sind dadurch besser zugänglich.If the crossbeam is open at the bottom, the sealing strips can Screwed inside of the traverse. The fittings are thereby more accessible.

Verglichen mit dem herkömmlichen Luftkasten besteht viel weniger die Gefahr einer Verschmutzung des Luftzuführ-Systems. Insbesondere kann das Eindringen von Papierresten in das Luftzuführ-System zumindest weitgehend vermieden werden, z. B. indem die Luftaustrittsöffnungen gemäß Fig. 4.1, 4.2 oder 5 mit einer Abdeckung 5.5 versehen werden.Compared to the conventional air box, there is much less danger contamination of the air supply system. In particular, it can Penetration of paper scraps into the air supply system at least largely be avoided, e.g. B. by the air outlet openings according to Fig. 4.1, 4.2 or 5 can be provided with a cover 5.5.

Die erfindungsgemäße Traverse kann, verglichen mit einem herkömmlichen Luftkasten, ein wesentlich geringeres Gewicht aufweisen (durch Verwendung geringerer Bleckdicken), weil die Belastung durch den Überdruck wesentlich geringer ist.The traverse according to the invention can be compared to a conventional one Air box, have a much lower weight (by use lower sheet thicknesses) because the pressure caused by the overpressure is significant is less.

Die unteren Seitenschilde 20 können gemäß Fig. 4.1 und 4.2 fest oder beweglich an der Traverse 5 befestigt werden; sie können aber auch isoliert von dieser abgestützt sein. Die oberen Seitenschilde 21 (Fig. 1) sind wie bisher unabhängig von den unteren Seitenschilden beweglich abgestützt. In einer weiteren Variante könnten die unteren an die oberen Seitenschilde gekoppelt und gemeinsam mit diesen axial geführt sein.The lower side plates 20 can be fixed according to FIGS. 4.1 and 4.2 be movably attached to the cross member 5; but they can also be isolated be supported by this. The upper side plates 21 (Fig. 1) are like hitherto supported independently of the lower side plates. In Another variant could be the lower to the upper side shields coupled and axially guided together with them.

Das Querverteilrohr 6 hat natürlich in jedem Falle auch einen Anschluß an eine Druckluftquelle 22 (Fig. 1). Er könnte an einer Stirnseite des Querverteilrohres angeordnet sein. Auch sind Druckluft-Zufuhranschlüsse an beiden Stirnseiten denkbar. Schließlich ist denkbar, an einer Längsseite einen oder mehrere Druckluft-Zufuhranschlüsse vorzusehen.The transverse distribution pipe 6 naturally also has a connection in every case a compressed air source 22 (Fig. 1). It could be on one face of the Be arranged cross-distribution pipe. Compressed air supply connections are also on conceivable on both ends. Finally, one is conceivable on one long side or to provide several compressed air supply connections.

Bei der Ausführungsform gemäß Fig. 6 wird die Papierbahn 3.1 von oben her an die Wickelmaschine herangeführt, d.h. in den Preßspalt zwischen der Tragwalze 1 und der entstehenden Papierrolle 3.2. Im Gegensatz zu jener Ausführung, bei der die Papierbahn 3.1 von unten her in den Zwischenraum zwischen den Tragwalzen 1 und 2 eingeführt wird, hat diese Ausführungsform den großen Vorteil, daß zwischen die einzelnen Lagen der entstehenden Papierrolle 3.2 keine Luft eingedrückt wird.In the embodiment according to FIG. 6, the paper web 3.1 is from above brought up to the winding machine, i.e. in the press nip between the Carrier roller 1 and the resulting paper roll 3.2. In contrast to that Version in which the paper web 3.1 from below into the space is inserted between the support rollers 1 and 2, this embodiment the great advantage that between the individual layers of the resulting Paper roll 3.2 no air is pressed.

Bei dieser Ausführungsform ist eine im wesentlichen plattenförmige Traverse 5 um eine Schwenkachse 5.6 verschwenkbar. Die Schwenkachse 5.6 verläuft parallel zu den Achsen der beiden Tragwalzen 1, 2. Zum Verschwenken der Traverse 5 dient ein Pneumatik-Antrieb 9. Auch hierbei sind wieder Dichtleisten 12, 13 vorgesehen, die berührend an den Mantelflächen der beiden Tragwalzen 1, 2 anliegen können.In this embodiment, an essentially plate-shaped cross-member 5 pivotable about a pivot axis 5.6. The pivot axis 5.6 runs parallel to the axes of the two support rollers 1, 2. For pivoting the Traverse 5 is used for a pneumatic drive 9 Sealing strips 12, 13 are provided, which are in contact with the lateral surfaces of the two support rollers 1, 2 can rest.

Das Querverteilrohr 6 ist mittels einer Vielzahl von Leitungen 7 durch die Traverse 5 hindurch an den Druckraum 10 angeschlossen.The cross distribution pipe 6 is by means of a plurality of lines 7 through the Traverse 5 connected to the pressure chamber 10.

Bei der Ausführungsform gemäß Fig. 7 wird die Papierbahn 3.1 von unten her in den Zwischenraum zwischen den beiden Tragwalzen 1, 2 eingeführt.7, the paper web 3.1 is from below introduced into the space between the two support rollers 1, 2.

Die Traverse 5 ist auch hier - wie bei der Ausführungsform gemäß Fig. 6 - im wesentlichen plattenförmig und um eine ortsfeste Achse 5.6 schwenkbar.The cross member 5 is here - as in the embodiment according to FIG. 6 - in essentially plate-shaped and pivotable about a fixed axis 5.6.

Das Querverteilrohr 6 kann ortsfest sein. Die Leitungen 7 sind am Querverteilrohr 6 starr angeschlossen.The cross distribution pipe 6 can be stationary. The lines 7 are on Cross manifold 6 rigidly connected.

Alternativ können - wie in Fig. 7 dargestellt - Querverteilrohr 6, Leitungen 7 und Traverse 5 eine starre Einheit bilden, die um eine Schwenkachse 6.3 des Querverteilrohres 6 verschwenkbar ist.Alternatively, as shown in FIG. 7, transverse distribution pipe 6, lines 7 and traverse 5 form a rigid unit which about a pivot axis 6.3 of the Cross distribution pipe 6 is pivotable.

Man erkennt ferner eine Bänderführung 30. Diese dient dem Einführen der Bahn 3.1. Sie ruht auf dem Querverteilrohr 6. Sie geht dann in Arbeitsposition, wenn die Traverse 5 aus ihrer Arbeitsposition entfernt wird. A band guide 30 can also be seen. This serves to introduce the Lane 3.1. It rests on the cross distribution pipe 6. It then goes into the working position, when the traverse 5 is removed from its working position.

Die Wickelmaschine weist ferner eine herkömmliche Trennvorrichtung 11 mit einer Schneide 11.1 auf, so wie in Figur 1 bereits dargestellt.The winding machine also has a conventional separating device 11 a cutting edge 11.1, as already shown in FIG.

Figur 8 zeigt eine weitere Ausführungsform einer erfindungsgemäßen Wickelmaschine. Hierbei wird die Papierbahn 3.1 von oben her in den Preßspalt zwischen Tragwalze 1 und entstehender Papierrolle 3.2 eingeführt. Der Wickelmaschine ist eine Perforiereinrichtung 40 vorgeschaltet, ferner mehrere über die Bahnbreite verteilte Klebstoffspender 50. Bezüglich der Einzelheiten solcher Vorrichtungen wird auf die Patentanmeldungen 195 19 306.7 und 295 08 732.9 verwiesen.Figure 8 shows a further embodiment of an inventive Winder. Here, the paper web 3.1 from above into the Press nip between support roller 1 and emerging paper roll 3.2 introduced. A perforating device 40 is connected upstream of the winding machine, furthermore several adhesive dispensers 50 distributed over the web width Details of such devices can be found in patent applications 195 19 306.7 and 295 08 732.9.

Die Wickelmaschine arbeitet mit einem Druckluftkasten 60. Dieser ist mittles eines Pneumatik-Antriebs 9 in seine hier dargestellte Arbeitsposition einfahrbar bzw. aus dieser anfahrbar. Dabei ist der Blaskasten mittels Schwenkhebeln 61 um eine Schwenkachse 62 schwenkbar.The winding machine works with a compressed air box 60. This is medium a pneumatic drive 9 retractable into its working position shown here or approachable from this. The blow box is by means of swivel levers 61 pivotable about a pivot axis 62.

Es ist eine Druckluftquelle 22 vorgesehen. Diese steht über eine oder mehrere Leitungen 7 mit dem Druckluftkasten 60 direkt in leitender Verbindung.A compressed air source 22 is provided. This stands above one or more Lines 7 with the compressed air box 60 directly in conductive connection.

Alternativ ist es auch möglich, ein Querventilrohr 6 vorzusehen, das über eine Vielzahl von Leitungen 70 an den Druckluftkasten 60 angeschlossen ist.Alternatively, it is also possible to provide a cross valve tube 6 which has a A plurality of lines 70 is connected to the compressed air box 60.

Die Wickelmaschine gemäß Fig. 9 ist ganz ähnlich aufgebaut wie jene gemäß Fig. 1. Die Besonderheit liegt in einer Bahntrennvorrichtung 11 und deren Anordnung in Bezug auf die Traverse 5. Die Bahntrennvorrichtung 11 ist nämlich an der Traverse 5 gelagert, so daß sie deren Hubbewegung infolge der Aktion des Antriebes 9 mitmacht. Die Trennvorrichtung umfaßt einen schmalen Tragbalken 11.3 für eine Schneide 11.1 und einen eigenen Antrieb 11.2. Dieser kann pneumatisch oder hydraulisch betrieben werden. Tragbalken und Antrieb sind mittels eines Gelenkstückes 11.4 mechanisch miteinander verbunden. Schenkel 5.1 der Traverse weist eine Öffnung 11.5 auf, durch welche der Tragbalken 11.3 hindurchgeführt ist, und in welcher er mittels des Antriebes 11.2 auf- und abfahrbar ist, und zwar zwischen einer nicht-operativen und einer operativen Position (die letzte gestrichelt dargestellt).The winding machine according to FIG. 9 is constructed very similarly to that according to FIG Fig. 1. The peculiarity lies in a web cutting device 11 and its Arrangement with respect to the traverse 5. The web separator 11 is namely mounted on the crossbar 5 so that they result in their lifting movement participates in the action of the drive 9. The separator includes one narrow support beam 11.3 for a cutting edge 11.1 and its own drive 11.2. This can be operated pneumatically or hydraulically. Support beam and drive are mechanical by means of a joint piece 11.4 connected with each other. Leg 5.1 of the traverse has an opening 11.5 on, through which the support beam 11.3 is passed, and in which it can be moved up and down by means of the drive 11.2, specifically between one non-operational and an operational position (the last dashed ) Shown.
