Abstract

A supporting beam 4 bears a hollow, box-shaped carrier 11, on which there is situated, substantially tangentially with respect to the circumferential surface of an associated guide roll 2, a presser surface 5 for the paster strip. A slot 6 for holding the paster strip A is situated perpendicularly to the presser surface on the box-shaped carrier 11. A considerable part of the paster strip A, from which the cover film has been removed, projects from said slot. Blowing means or blowing channels 9 with blowing ports 10 bend upwards that part of the paster strip projecting from the slot 6, so that, as the supporting beam 4 moves nearer to the guide roll 2, said part of the paster strip lies practically against the presser surface 5. In this way, the paster strip can be fastened on the end of the web, which is wrapped over the guide roll 2. <IMAGE>

Description

Bei der Herstellung von gestrichenem Papier ist es notwendig, eine Verbindung zwischen dem ablaufenden Ende eines Tambours mit dem Anfangsende eines neuen Tambours herzustellen, wobei üblicherweise ein Klebeband oder Klebestreifen verwendet werden. Dabei sind diese Bänder oder Streifen im allgemeinen doppelseitig mit Klebemasse beschichtet. Entsprechend umständlich ist die Anbringung des Klebebandes oder -streifens am Ende der Warenbahn und am Tambour, den die Warenbahn bildet. Dies wurde bisher in mühseliger Handarbeit durchgeführt.In the manufacture of coated paper, it is necessary to make a connection between the end of a reel and the beginning of a new reel, usually using an adhesive tape or tape. These tapes or strips are generally coated on both sides with adhesive. The application of the adhesive tape or strip to the end of the web and to the drum that the web forms is correspondingly cumbersome. So far, this has been carried out by hand.

Die Aufgabe der Erfindung ist es daher, eine Einrichtung anzugeben, bei der die einzelnen Vorgänge im wesentlichen maschinell durchgeführt werden. Die Lösung dieser Aufgabe gelingt bei einem im wesentlichen einseitig mit Klebstoff beschichtetem Klebeband, das nur im Bereich einer Längskante eine weitere Klebeschicht auf seiner anderen Seite aufweist gemäß einer durch die Merkmale des Anspruchs 1 definierten Vorrichtung.The object of the invention is therefore to provide a device in which the individual processes are carried out essentially by machine. This object is achieved with an adhesive tape which is essentially coated on one side with adhesive and which only has a further adhesive layer on its other side in the region of one longitudinal edge, in accordance with a device defined by the features of claim 1.

Es ist dabei so, daß sich die Leitwalze in der Nähe des neu einzuwechselnden Tambours befindet, so daß das Ende der Warenbahn, aus dem der Tambour gewickelt ist, über die Leitwalze hinweg geschlagen werden kann. Es erfolgt dann ein Abtrennen des Endes der Warenbahn an einer bestimmten Stelle, an welcher auch durch eine von einem Tragbalken gehaltene Haltefläche das in einem Schlitz des Tragbalkens gehaltene Klebeband an das neue Warenbahnende angeklebt wird. Dabei ragt der Klebestreifen nur mit dem Teil aus dem Schlitz heraus, dessen Klebeflächenteil für die Anheftung an die Warenbahn bloßgelegt, d.h. im allgemeinen von einer Deckfolie zuerst befreit wird. Dieses Ende wird von einer Blasvorrichtung in die Nähe der Anpreßfläche gebracht, wobei der Klebestreifen im Querschnitt zu einem Winkel verformt wird.It is the case that the guide roller is in the vicinity of the reel to be replaced, so that the end of the web from which the reel is wound can be knocked over the guide roller. The end of the web is then cut off at a specific point, at which the adhesive tape held in a slot in the beam is also adhered to the new web end by a holding surface held by a supporting beam. The adhesive strip sticks out only with the part out of the slot, the adhesive surface part of which is exposed for attachment to the web, ie generally first of all a cover film is removed. This end is brought into the vicinity of the pressing surface by a blowing device, the adhesive strip being deformed at an angle in cross section.

Nachfolgend wird die Erfindung anhand der in den Figuren der Zeichnung beschriebenen Ausführungsbeispiele erläutert, wobei im wesentlichen nur ein einziges Ausführungsbeispiel dargestellt ist.The invention is explained below with reference to the exemplary embodiments described in the figures of the drawing, essentially only a single exemplary embodiment being shown.

In Fig. 1 liegt das von dem Tambour C losgelöste Bahnende H über der Leitwalze 2 und hängt hier an deren linken Seite herunter. Dabei weist die als Hohlwalze ausgebildete Leitwalze einen gummi-elastischen Mantel 22 aus Kunststoff auf. Etwa in der Höhe der Mittelachse der Leitwalze befindet sich eine Anpreßfläche 5, welche hier von einer Leiste aus gummi-elastischem Material gebildet ist. Diese ist an einem kastenförmigen Träger 11 befestigt, welcher von dem Tragbalken 4 gehalten ist. Dieser Tragbalken ist, ebenso wie der kastenförmige Träger 11 und die Anpreßleiste 5 parallel zur Zentralachse der Leitwalze 2 und des Tambours C angeordnet und weist eine Schwenkachse 19 auf, die ebenfalls diese Richtung hat. Ebenfalls in dieser Richtung und mit der gleichen Länge angeordnet befindet sich unter dem kastenförmigen Träger 11 ein Halteschlitz 6 und ein mit Schneidkante 8 versehenes Messer 7, das als ein Federstahlwinkel ausgebildet ist. Dieses Messer wird mittels einem Druckschlauch 12 in die Schneidposition gebracht. Das Messer ist mittels einer Klemmleiste 13 an dem Tragbalken 4 befestigt. Unterhalb des Messers 7 befinden sich Blaskanäle 9 mit Mündungen 10 für Blasluft. Weitere Blaskanäle 15 befinden sich unterhalb dieser Blaskanäle und sind an einem zentralen Luftkanal 14 angeschlossen, der sich ebenfalls parallel zur Zentralachse der Leitwalze 2 erstreckt. Unterhalb der Blaskanäle 15 ist eine Leitfläche 16 angeordnet, die im allgemeinen aus dünnem Blech besteht. Wie dargestellt, wird von dieser Leitfläche das Bahnende H in einer zum Schneiden geeigneten Position gehalten. Es erleichtert auch das Einfädeln der Papierbahn und das Abwickeln von mehreren Meter Papierbahn vom Tambour.In Fig. 1, the web end H detached from the drum C lies above the guide roller 2 and hangs down here on the left side thereof. The guide roller, which is designed as a hollow roller, has a rubber-elastic jacket 22 made of plastic. Approximately at the height of the central axis of the guide roller is a pressure surface 5, which is formed here by a strip made of rubber-elastic material. This is attached to a box-shaped support 11 which is held by the support beam 4. This support beam, like the box-shaped support 11 and the pressure strip 5, is arranged parallel to the central axis of the guide roller 2 and the spool C and has a pivot axis 19 that also has this direction. Also arranged in this direction and with the same length, there is a holding slot 6 under the box-shaped support 11 and a knife 7 provided with a cutting edge 8, which is designed as a spring steel angle. This knife is brought into the cutting position by means of a pressure hose 12. The knife is fastened to the supporting beam 4 by means of a clamping strip 13. Below the knife 7 there are blowing channels 9 with openings 10 for blowing air. Further blowing channels 15 are located below these blowing channels and are connected to a central air channel 14, which also extends parallel to the central axis of the guide roller 2. A guide surface 16, which generally consists of thin sheet metal, is arranged below the blowing channels 15. As shown, the web end H is held in a position suitable for cutting by this guide surface. It also facilitates threading the paper web and unwinding several meters of paper web from the reel.

Es wird ein Klebeband verwendet, das im wesentlichen auf einer Seite vollständig von einer Klebeschicht bedeckt ist, welche von einer in der Längsrichtung des Klebebandes unterteilten Deckfolie D abgedeckt ist. Auf der anderen Seite weist das Klebeband einen schmalen Klebestreifen in der Nähe seiner einen Längskante auf, der aus einer Klebschicht F und einer Deckfolie E besteht. In Fig. 2 ist das Klebeband A in der Position in dem Schlitz 6 dargestellt, in welcher es sich nach dem Ansaugen (6) und dem Hochblasen des bereits von der Deckfolie befreiten Teiles durch die Blasöffnungen 10 befindet. Die Deckfolie wird erst dann entfernt, wenn das Klebeband ganz an die Fläche 5 und 6 angesaugt worden ist. Wenn die Düsen 10 blasen, wird die Fläche 5 besaugt, so daß das Klebeband direkt an der Fläche 5 anliegt. Nach weiterer Annäherung des Tragbalkens 4 bzw. der Anpreßfläche 5 durch Schwenken des Tragbalkens um die Schwenkachse 19 kann in dieser Position dann die Verbindung des Klebebandes mit dem Bahnende erfolgen, wobei das überflüssige Bahnende H von dem Messer 7 abgeschnitten wird. Auch zu diesem Zweck ist der Kunststoff-Mantel 22 der Leitwalze 2 vorzusehen. Ein gut geeigneter Kunststoff ist Polyurethan. Das Messer 7 trennt mit seiner Schneidkante 8 das überflüssige Bahnende praktisch direkt unterhalb des Beginns der Anpreßfläche 5 ab, so daß das Klebeband praktisch Stoß an Stoß bezüglich des noch verbliebenen Deckfolienteils D und des Warenbahnendes aufgeklebt wird.An adhesive tape is used which is essentially completely covered on one side by an adhesive layer which is covered by a cover film D divided in the longitudinal direction of the adhesive tape. On the other hand, the adhesive tape has a narrow adhesive strip near its one longitudinal edge, which consists of an adhesive layer F and a cover film E. 2, the adhesive tape A is shown in the position in the slot 6, in which it is after the suction (6) and the blowing up of the part already freed from the cover film through the blowing openings 10. The cover film is only removed when the adhesive tape has been completely sucked onto the surface 5 and 6. When the nozzles 10 blow, the surface 5 is vacuumed, so that the adhesive tape lies directly on the surface 5. After the support beam 4 or the contact surface 5 has been brought closer to one another by pivoting the support beam about the pivot axis 19, the adhesive tape can then be connected to the end of the web in this position, the unnecessary Web end H is cut off by the knife 7. The plastic jacket 22 of the guide roller 2 must also be provided for this purpose. A very suitable plastic is polyurethane. The knife 7 separates with its cutting edge 8 the superfluous end of the web practically directly below the start of the pressing surface 5, so that the adhesive tape is glued practically abutting with respect to the remaining cover film part D and the end of the web.

Nach dem Kleben kann möglicherweise durch Umstellen von Saugen auf Blasen an den Flächen 5 und 6 (Schlitz) das Herausziehen des Klebebandes aus letzterem erleichtert werden.After gluing, changing the suction to bubbles on surfaces 5 and 6 (slit) can make it easier to pull out the adhesive tape from the latter.

In Fig. 3 ist die Lage des Klebebandes nach Rückrollen des Bahnendes auf den Tambour C dargestellt. Hierbei ist auch die Deckfolie E des kleinen Klebebandes entfernt worden, so daß das Ende der Warenbahn mittels des Klebebandes A stramm am Tambour C befestigt werden konnte. Das Klebeband A trägt noch den zweiten Deckfolienteil D. Kurz vor dem Beginn des eigentlichen Splice-Vorganges wird dieser Deckfolienteil dann schließlich entfernt.3 shows the position of the adhesive tape after the web end has been rolled back onto the reel C. Here, the cover film E of the small adhesive tape has also been removed, so that the end of the web by means of the adhesive tape A could be attached to the drum C tightly. The adhesive tape A still carries the second cover film part D. Shortly before the actual splice process begins, this cover film part is then finally removed.

Die Blasluftkanäle 15 dienen dazu, das Bahnende H ohne menschliche Hilfe in die richtige Position und nach unten wegzuleiten.The blown air channels 15 serve to guide the web end H into the correct position and down without human help.

Hinsichtlich der Annäherung von Leitwalze 2 und Tambour C wird auf Fig. 4 verwiesen. In diesem Falle ist die Leitwalze 2 fest (allerdings um ihre Zentralachse drehbar) angeordnet und die Annäherung von Leitwalze 2 und Tambour c erfolgt durch die Lagerung des Tambours C, die mittels Spindel 27 in horizontaler Richtung verstellbar ist. Die eigentliche Lagerstelle 26 des Tambours weist eine Neigung auf, so daß dessen Lagerachse immer eine bestimmte Stellung in bezug auf die Tambourlagerung hat. Diese Lagerung 25 befindet sich auf einem Tambourwagen 24. Die Klebenaht auf einem Tambourwagen vorzubereiten, ist der schwierigste Fall; normalerweise wird der Tambour an einem Ständer mit schräger Laufbahn mit einem Kran abgelegt.With regard to the approach of guide roller 2 and drum C, reference is made to FIG. 4. In this case, the guide roller 2 is fixed (but rotatable about its central axis) and the approach of the guide roller 2 and drum c takes place through the storage of the drum C, which can be adjusted in the horizontal direction by means of the spindle 27. The actual bearing point 26 of the drum has an incline, so that its bearing axis always has a certain position with respect to the drum bearing. This bearing 25 is located on a reel 24. Preparing the adhesive seam on a reel is the most difficult case; usually the drum is placed on a stand with a sloping track with a crane.

Man erkennt aus dieser Figur, daß die Anpreßfläche 5 im wesentlichen auf dem gleichen Höhenniveau wie die Zentralachse 18 der Leitwalze 2 sich befindet. Unterhalb der Leitwalze 2 wird noch ein Ableitblech 33 für das Warenbahnende H vorgesehen, wobei mittels an einem zentralen Luftkanal 30 angeschlossene Blaskanäle 31 das Bahnende von der Leitwalze 2 abgeführt werden kann. Zusätzliche Blasöffnungen des Luftkanals 30 richten Luftströme im wesentlichen tangential zur Leitwalze in deren untersten Bereich, so daß das Bahnende H entlang der Leitfläche 33 abgleiten muß.It can be seen from this figure that the contact surface 5 is essentially at the same level as the central axis 18 of the guide roller 2. Below the guide roller 2 there is also a deflector plate 33 for the web end H, wherein the web end can be removed from the guide roller 2 by means of blowing channels 31 connected to a central air duct 30. Additional blowing openings of the air duct 30 direct air flows essentially tangentially to the guide roller in its lowermost region, so that the web end H must slide along the guide surface 33.

In Fig. 5 ist noch an einer Einzelheit dargestellt, wie der Tambour C vor dem Bearbeitsvorgang mit dem Klebeband aussieht. Dabei ist hier auf seiner linken Seite das Bahnende dargestellt, das mittels Klebestreifen I am Umfang des Tambours C befestigt ist.5 shows a detail of how the drum C looks before the processing operation with the adhesive tape. The end of the web is shown here on its left side, which is attached to the circumference of the drum C by means of adhesive tape I.

Es ist auch ein Tragbalken möglich, der um eine zentrale Schwenkachse schwenkbar ist. Dementsprechend ist die Anpreßfläche dann auch gekrümmt ausgeführt mit einem Krümmungsmittelpunkt, der in dieser Schwenkachse liegt. Durch Verdrehen der Leitwalze um einen dementsprechenden Winkelbetrag kann dann auch das Klebeband an dem Warenbahnende befestigt werden, was dann anzuwenden ist, wenn der Durchmesser der Leitwalze relativ klein gehalten werden müßte.A support beam is also possible, which can be pivoted about a central pivot axis. Accordingly, the contact surface is then also curved with a center of curvature that lies in this pivot axis. By rotating the guide roller by a corresponding angle, the adhesive tape can also be attached to the end of the web, which is to be used when the diameter of the guide roller would have to be kept relatively small.

In Fig. 4 ist noch dargestellt, daß auch die Leitwalze 2 beweglich an seitlichen Schwenkarmen (strichpunktiert dargestellt) gelagert werden kann. Weitere, mit diesen Schwenkarmen verbundene strichpunktiert dargestellte Schwenkarme 38 gestatten es dann, mittels der angedeuteten hydraulischen Hubelemente den Tragbalken 4 bzw. die Anpreßfläche 5 an die Leitwalze 2 heranzuschwenken.In Fig. 4 it is also shown that the guide roller 2 can be movably mounted on side pivot arms (shown in dash-dot lines). Further swivel arms 38 connected to these swivel arms and shown in dash-dot lines then allow the support beam 4 or the pressing surface 5 to be swiveled towards the guide roller 2 by means of the hydraulic lifting elements indicated.

Die Leitwalze 2 kann mit Bohrungen in ihrem Mantel versehen werden, so daß mittels in ihrem Inneren angebrachtem Unterdruck das Warenbahnende an die Mantelfläche der Leitwalze 2 angesaugt werden kann. Bringt man dann den Tambour C in eine Position, in welcher er an der Leitwalze 2 anliegt, kann durch Drehen des Tambours C mittels der Leitwalze, die mit einem Motor gekuppelt ist, in Uhrzeigerrichtung das Warenbahnende entlang der Mantelfläche der Leitwalze 2 hin zu den Leitflächen 16 und 33 geführt werden. In umgekehrter Richtung wird der Klebestreifen A dann fest mit dem Tambour verbunden.The guide roller 2 can be provided with holes in its jacket, so that the web end can be sucked onto the jacket surface of the guide roller 2 by means of a vacuum applied inside it. If you then bring the reel C in a position in which it rests on the guide roller 2, by rotating the reel C by means of the guide roller, which is coupled to a motor, clockwise the end of the web along the outer surface of the guide roller 2 towards the guide surfaces 16 and 33 are performed. In the opposite direction, the adhesive strip A is then firmly connected to the drum.

Die ganze Anordnung ist günstigerweise so vorzusehen, daß die Leitwalze im unteren Quadranten des Tambours C angeordnet ist, wobei sie vorzugsweise so tief angeordnet ist, daß die gemeinsame Tangente von ihr und dem Tambour C größtmöglichen Durchmessers im wesentlichen horizontal verläuft.The entire arrangement is advantageously to be provided in such a way that the guide roller is arranged in the lower quadrant of the drum C, it preferably being arranged so deep that the common tangent of it and the drum C of the largest possible diameter is essentially horizontal.

Es ist natürlich nicht unbedingt nötig, daß ein Tambourwagen bei dem Befestigungsvorgang des Klebestreifens an dem Tambour benutzt wird. Man könnte statt dessen auch einen Auflagebock verwenden, der vorzugsweise als Haltefläche eine schiefe Ebene hat, so daß der Tambour aufgrund dieser Neigung mit einem gewissen Auflagedruck an der Leitwalze 2 anliegt.It is of course not absolutely necessary for a drum wagon to be used in the process of attaching the adhesive strip to the drum. Instead, one could also use a support block, which preferably has an inclined plane as a holding surface, so that the drum rests against the guide roller 2 with a certain contact pressure due to this inclination.

Andererseits könnte auch dieser Bock Hebel aufweisen, die die Achse des Tambours durch pneumatische Hubelemente bremsen oder auch vorwärtsschieben, so daß man eine gesteuerte Anpreßkraft des Tambours C an der Leitwalze 2 erzeugen könnte.On the other hand, this trestle could also have levers which brake or push the axis of the drum by pneumatic lifting elements, so that one could generate a controlled pressing force of the drum C on the guide roller 2.

Der Gesichtspunkt ist allgemein, daß die Anordnung ohne Laufstege vom Personal bedient werden kann.The general point of view is that the arrangement can be operated by the staff without catwalks.

Es gibt zwei Möglichkeiten der Klebenahtvorbereitung:

I:
Die Leitwalze ist "ortsfest"; der Balken ist schwenkbar, dann muß der Tambour je nach Durchmesser zu der Leitwalze zugeführt werden, z.B. wird mittels Kran der Tambour an eine "schräge Laufbahn" gelegt oder am Tambourwagen, z.B. mittels Spindel, zur Leitwalze geschoben. Angepreßt wird entweder mit Hubzylinder oder mit "Eigengewichts-Komponente" in Horizontal-Richtung.
II:
Bei dieser Variante ist der Tambour ortsfest; dann muß von dessen Durchmesser abhängig die gesamte Vorrichtung (Leitwalze und Balken) an den Tambour herangeschwenkt werden.
There are two ways to prepare the glued seam:
I:
The guide roller is "stationary"; the bar can be swiveled, then the reel must be fed to the guide roller depending on the diameter, for example, the reel is placed on an "inclined track" using a crane or pushed to the guide roller on the reel spool, eg using a spindle. Is pressed either with a lifting cylinder or with "dead weight component" in the horizontal direction.
II:
In this variant, the drum is stationary; then, depending on its diameter, the entire device (guide roller and beam) must be pivoted towards the reel.

Vorteilhaft wird das Klebeband in den Schlitz 6 mit einem Transportriemen, z.B. Flachriemen, eingezogen.The adhesive tape is advantageously placed in the slot 6 with a transport belt, e.g. Flat belt, drawn in.

Bei der Ausführungsform nach Fig. 6 ist eine Messerklinge 20 vorgesehen, die vollständig parallel zur Ebene des Schlitzes 6 verläuft und auch allein in dieser Richtung beweglich angeordnet ist. Das Messer ist dabei gehalten durch eine Führungsleiste 23, die in einer Schwalbenschwanzführung geführt ist, sowie durch Führungsklötzer 28, die an das Messer angeschraubt sind. Diese Führungsklötzer sind geführt in schräg angeordneten Schlitzen 29 der Führungsleiste 23. Bei einer Axialverschiebung der letzteren, also in Richtung deren Längsachse, wird dabei das Messer quer zu dieser Verschiebungsrichtung verschoben und schneidet dadurch das überflüssige Papierbahnende an der Leitwalze 2 ab, nachdem der Klebestreifen an der Anpreßfläche 5 vollständig anliegt. In dieser Figur sind auch die Saugöffnungen 40, die von dem hohlen Träger 11 zur Anpreßfläche 5 führen und durch diese hindurchgehen, dargestellt. Ferner sind auch die Blasöffnungen 41 vorhanden, die an den Blasluftkanal 42 angeschlossen sind, welcher mittels Dichtungen 43 gegenüber dem Tragbalken abgedichtet ist. Es können weitere Saugöffnungen 45 des hohlen Trägers 11 vorgesehen werden, um den Klebestreifen in dem Schlitz 6 zu fixieren. Dies ist allerdings auch möglich (z.B. dann, wenn man keinen Hohlträger 11 verwendet) durch einen Druckschlauch 21. Mittels diesem Druckschlauch könnte anstelle der Führungsleiste 23 auch die Betätigung des Messers 20 erfolgen, wenn dieses an seinem dem Druckschlauch zugewandten Ende eine Druckleiste - wie strichpunktiert dargestellt - aufweisen würde. Das Messer würde dann durch Bandfedern 46 - wie ebenfalls strichpunktiert dargestellt - in die Ruheposition zurückgeführt werden können.In the embodiment according to FIG. 6, a knife blade 20 is provided which runs completely parallel to the plane of the slot 6 and is also arranged to be movable in this direction alone. The knife is held by a guide bar 23, which is guided in a dovetail guide, and by guide blocks 28, which are screwed onto the knife. These guide blocks are guided in obliquely arranged slots 29 of the guide bar 23. When the latter is axially displaced, that is to say in the direction of its longitudinal axis, the knife is displaced transversely to this direction of displacement and thereby cuts off the superfluous end of the paper web on the guide roller 2 after the adhesive strip has been applied the contact surface 5 rests completely. In this figure, the suction openings 40, which lead from the hollow support 11 to the contact surface 5 and pass through it, are also shown. Furthermore, there are also the blowing openings 41 which are connected to the blowing air duct 42 are, which is sealed by means of seals 43 against the support beam. Further suction openings 45 of the hollow carrier 11 can be provided in order to fix the adhesive strip in the slot 6. However, this is also possible (for example if a hollow beam 11 is not used) by means of a pressure hose 21. Instead of the guide bar 23, this knife hose could also be used to actuate the knife 20 if it has a pressure bar at its end facing the pressure hose - as is dot-dashed shown - would have. The knife would then be able to be returned to the rest position by ribbon springs 46, as also shown in dash-dot lines.
