Description

Der Inhalt der deutschen Patentanmeldung DE 10 2012 212 699.6 wird durch Bezugnahme hierin aufgenommen.The content of the German patent application DE 10 2012 212 699.6 is incorporated herein by reference.

Die Erfindung betrifft eine Maschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a machine according to the preamble of claim 1.

Derartige Maschinen sind beispielsweise aus der EP 1 086 805 B1 bekannt, wobei eine Leimauftragswalze mittels Andrückeinrichtungen in Richtung auf die Riffelwalze beaufschlagbar ist, mittels derer die Leimauftragswalze mit einem vorgegebenen Anpressdruck gegen die auf der Riffelwalze befindliche Papierbahn gedrückt wird, um eine gleichmäßige Beleimung der Spitzen der Wellungen der Papierbahn zu ermöglichen. An der Leimauftragswalze sind Anlaufringe angebracht, die nur geringfügig über die Oberfläche der Leimauftragswalze vorstehen. Zur Kalibrierung des zwischen Riffelwalze und Leimauftragswalze zu bildenden Beleimungsspalts wird die Leimauftragswalze mittels der Andrückeinrichtungen gegen die Riffelwalze gedrückt, wobei die Anlaufringe gegen die Riffelung anliegen. Anschließend wird die Leimauftragswalze wieder um ein vorgegebenes Maß von der Riffelwalze weggefahren. Alternativ können auch die Anlaufringe weggelassen werden. Zur Kalibrierung wird hierbei die Leimauftragswalze direkt gegen die Riffelwalze zugestellt.Such machines are for example from the EP 1 086 805 B1 known, wherein a glue application roller can be acted upon by pressing means in the direction of the corrugating roller, by means of which the glue application roller is pressed with a predetermined contact pressure against the paper web located on the corrugating roller to allow a uniform gluing of the tips of the corrugations of the paper web. At the glue application roller contact rings are attached, which protrude only slightly above the surface of the glue applicator roll. In order to calibrate the gluing gap to be formed between corrugating roller and glue application roller, the glue application roller is pressed against the corrugating roller by means of the pressing devices, the abutment rings abutting against the corrugation. Subsequently, the glue application roller is moved away again by a predetermined amount of the corrugating roller. Alternatively, the thrust rings can be omitted. For calibration, in this case the glue application roller is delivered directly against the corrugating roller.

In der Praxis hat sich gezeigt, dass beim Riss einer Papierbahn die Leimauftragswalze auf die Riffelwalze aufprallen kann, wodurch die Oberfläche der Riffelung beschädigt werden kann.In practice, it has been found that when a web of paper breaks, the glue applicator roll can impinge on the corrugating roll, which can damage the surface of the corrugation.

Aus der DE 100 50 348 C2 ist es bekannt, auf den Achsen von Riffelwalzenpaaren aufeinander abrollende Scheiben vorzusehen, um einen vorgegebenen Spalt zwischen den Riffelungen der beiden ineinandergreifenden Riffelwalzen sicherzustellen.From the DE 100 50 348 C2 It is known to provide on the axes of Riffelwalzenpaaren successive rolling discs to ensure a predetermined gap between the corrugations of the two intermeshing corrugating rolls.

Der Erfindung liegt die Aufgabe zugrunde, eine Maschine der gattungsgemäßen Art so auszugestalten, dass eine Beschädigung der Riffelung der Riffelwalze durch Aufschlag der Leimauftragswalze bei einem Papierriss oder dergleichen unterbunden wird.The invention has for its object to design a machine of the generic type so that damage to the corrugation of the corrugating roll is prevented by impact of the glue applicator roll in a paper tear or the like.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale im Kennzeichnungsteil des Anspruchs 1 gelöst. Der Kern der Erfindung liegt darin, dass dann, wenn zwischen Leimauftragswalze und Riffelwalze sich keine Papierbahn befindet, ein Aufprall der Leimauftragswalze auf die Riffelung der Riffelwalze vermieden wird, ohne dass die Abstandshalter in irgendeiner Form mit der Riffelung der Riffelwalze oder der Oberfläche der Leimauftragswalze in Kontakt kommen können. Während des normalen Betriebs, wenn sich also eine Papierbahn zwischen Leimauftragswalze und Riffelwalze befindet, sind der oder die Abstandshalter nicht in Funktion, das heißt sie sind also nicht im Eingriff miteinander. Durch die Reinigungsschaber ist die Betriebseinheit der Abstandshalter sichergestellt.This object is achieved by the features in the characterizing part of claim 1. The essence of the invention is that when there is no paper web between the glue applicator roll and the corrugating roll, an impact of the glue applicator roll on the corrugation of the corrugating roll is avoided, without the spacers having any shape with the corrugation of the corrugating roll or the surface of the glue applicator roll Contact can come. During normal operation, ie when there is a paper web between the glue applicator roll and the corrugating roll, the spacer or spacers are not in function, that is to say they are not in engagement with one another. The cleaning scraper ensures the operating unit of the spacers.

Der Sicherheitsspalt ist kleiner als die dünnste in der Praxis vorkommende Papierbahn. Ein Dickenbereich ergibt sich aus Anspruch 2.The safety gap is smaller than the thinnest paper web occurring in practice. A thickness range results from claim 2.

Die konkrete Ausgestaltung der Abstandshalter ergibt sich aus den Ansprüchen 3 bis 5.The specific embodiment of the spacers results from the claims 3 to 5.

Durch die Ausgestaltung nach Anspruch 6 ist sichergestellt, dass immer eine gleichmäßig symmetrische Führung gewährleistet ist.The embodiment according to claim 6 ensures that a uniformly symmetrical guidance is always ensured.

Anspruch 7 gibt eine bekannte Andrückeinrichtung wieder, die Ursache für einen Aufprall der Leimwalze auf die Riffelung der Riffelwalze bei einem Riss der Papierbahn sein kann.Claim 7 is a known pressing device again, which may be the cause of an impact of the glue roller on the corrugation of the corrugating roller at a crack of the paper web.

Fig. 2
a horizontal longitudinal section through the machine according to Fig. 1 , and
Fig. 3
a horizontal longitudinal section through a slightly modified embodiment of the machine for producing a one-sided laminated corrugated cardboard web in a representation accordingly Fig. 2 ,

Ein Maschinengestell 1 einer Maschine zur Herstellung einer einseitig kaschierten Wellpappebahn weist zwei zueinander parallele Seitenwände 2, 3 auf, in denen eine untere Riffelwalze 4 und eine obere Riffelwalze 5 gelagert sind. Wie aus Fig. 2 nur für die obere Riffelwalze 5 hervorgeht, sind diese über Wellenzapfen 6 in Lagern 7 gelagert, die in den Seitenwänden 2 beziehungsweise 3 abgestützt sind. Die Riffelwalzen 4, 5 weisen zueinander parallele Achsen 8, 9 auf. An ihren Zylinderoberflächen sind die Riffelwalzen 4, 5 mit sich parallel zu den Achsen 8, 9 erstreckenden Riffelungen 10, 11 versehen, die im Berührungsbereich 12 der beiden Riffelwalzen 4, 5 miteinander kämmen. Eine der Riffelwalzen 4, 5, und zwar üblicherweise die obere Riffelwalze 5, ist in Drehrichtung 13 antreibbar, während die andere Riffelwalze, üblicherweise also die untere Riffelwalze 4, in Drehrichtung 14 von der anderen Riffelwalze 5 mitgenommen wird.A machine frame 1 of a machine for producing a single-faced corrugated cardboard web has two mutually parallel side walls 2, 3, in which a lower corrugating roll 4 and an upper corrugating roll 5 are mounted. How out Fig. 2 only emerges for the upper corrugating roller 5, these are mounted on shaft journals 6 in bearings 7, which are supported in the side walls 2 and 3 respectively. The corrugating rolls 4, 5 have mutually parallel axes 8, 9. At their cylinder surfaces are the corrugating rollers 4, 5 with parallel to the axes 8, 9 extending corrugations 10, 11 which mesh with each other in the contact area 12 of the two corrugating rolls 4, 5. One of the corrugating rolls 4, 5, usually the upper corrugating roll 5, is drivable in the direction of rotation 13, while the other corrugating roll, usually the lower corrugating roll 4, is taken along by the other corrugating roll 5 in the direction of rotation 14.

In Drehrichtung 13 beziehungsweise 14 dem Berührungsbereich 12 nachgeordnet, ist eine Leimauftragseinrichtung 15 im Maschinengestell 1 angeordnet, die einen im Maschinengestell 1 gehaltenen Leimbehälter 16 aufweist. In diesem ist eine Leimauftragswalze 17 gelagert, die von einem Antriebsmotor 18 drehantreibbar ist. Die Leimauftragswalze 17 taucht in ein Leimbad 19 ein, oberhalb dessen eine Abquetschwalze 20 angeordnet ist, die ebenfalls im Leimbehälter 16 gelagert ist und mit der Leimauftragswalze 17 einen Leimspalt begrenzt. Die Leimauftragswalze 17 wird mittels Andrückeinrichtungen 21 mit einer vorgegebenen Kraft in Richtung auf die obere Riffelwalze 5 beaufschlagbar. Diese Andrückeinrichtungen 21 sind als hydraulisch beaufschlagbare Kolben-Zylinder-Antriebe ausgebildet, wie in der Zeichnung angedeutet ist. Diese Andrückeinrichtungen 21 und ihre Ansteuerung sind aus der EP 1 086 805 B1 (entsprechend US 6 692 602 B1 ) bekannt, worauf verwiesen werden darf.Downstream of the contact region 12 in the direction of rotation 13 or 14, a glue application device 15 is arranged in the machine frame 1, which has a glue container 16 held in the machine frame 1. In this, a glue applicator roll 17 is mounted, which is driven in rotation by a drive motor 18. The glue application roller 17 is immersed in a glue bath 19, above which a squeegee roller 20 is arranged, which is likewise mounted in the glue container 16 and delimits a glue gap with the glue application roller 17. The glue application roller 17 is acted upon by pressing means 21 with a predetermined force in the direction of the upper corrugating roller 5. These pressure devices 21 are designed as hydraulically acted piston-cylinder actuators, as indicated in the drawing. These pressing devices 21 and their control are from the EP 1 086 805 B1 (corresponding US Pat. No. 6,692,602 B1 ), which may be referred to.

Oberhalb der oberen Riffelwalze 5 ist eine Anpresseinrichtung 22 vorgesehen, die eine zylindrische Umlenkwalze 23, eine Spannwalze 24 und ein Anpressband 25 aufweist. Das Anpressband 25 liegt gegen die Riffelung 11 der oberen Riffelwalze 5 an und läuft drehrichtungsgleich mit dieser entsprechend dem Pfeil 26 um. Die Ausgestaltung derartiger Anpresseinrichtungen 22 ist allgemein bekannt.Above the upper corrugating roller 5, a pressing device 22 is provided, which has a cylindrical guide roller 23, a tension roller 24 and a pressure belt 25. The pressure belt 25 rests against the corrugation 11 of the upper corrugating roller 5 and reverses the direction of rotation with this according to the arrow 26. The design of such pressing devices 22 is well known.

Wie insbesondere Fig. 1 entnehmbar ist, wird in dem Berührungsbereich 12 zwischen unterer Riffelwalze 4 und oberer Riffelwalze 5 eine Papierbahn 27 eingeführt, die durch die Riffelungen 10, 11 mit einer Wellung 28 versehen wird. Die Spitzen 29 der jeweiligen Wellung 28 werden in der Leimauftragseinrichtung 15 von der Leimauftragswalze 17 mit Leim versehen. Die übrigen Bereiche der gewellten Papierbahn 27 werden nicht beleimt. Über die Umlenkwalze 23 wird eine Kaschierbahn 30 zugeführt, die ebenfalls aus Papier besteht und die gleiche Breite aufweist, wie die Papierbahn 27. Diese Kaschierbahn 30 wird von dem Anpressband 25 mitgenommen und in dem zwischen Anpressband 25 und oberer Riffelwalze 5 gebildeten Anpressbereich 31 an die Spitzen 29 der in der Riffelung 11 der oberen Riffelwalze 5 liegenden, gewellten Papierbahn 27 gedrückt und mit dieser verbunden. Die obere Riffelwalze 5 wird in üblicher Weise beheizt. Die fertig verleimte, einseitig mit einer Kaschierbahn 30 kaschierte Wellpappebahn 32 läuft zusammen mit dem Anpressband 25 von der oberen Riffelwalze 5 ab. Von dort wird sie in Abziehrichtung 33 einer Aufwickeleinrichtung zugeführt.In particular Fig. 1 is removed, in the contact region 12 between the lower corrugating roll 4 and upper corrugating roll 5, a paper web 27 is introduced, which is provided by the corrugations 10, 11 with a corrugation 28. The tips 29 of the respective corrugation 28 are provided in the glue applicator 15 of the glue applicator roll 17 with glue. The remaining areas of the corrugated paper web 27 are not glued. About the guide roller 23, a laminating 30 is fed, which also consists of paper and has the same width as the paper web 27. This laminating 30 is taken from the Anpressband 25 and formed in the between pressing belt 25 and upper corrugating roll 5 Anpressbereich 31 to the Tips 29 of lying in the corrugation 11 of the upper corrugating roll 5, corrugated paper web 27 is pressed and connected thereto. The upper corrugating roll 5 is heated in the usual way. The finished glued, one side laminated with a liner 30 corrugated board 32 runs together with the Anpressband 25 of the upper corrugating roll 5 from. From there it is fed in stripping direction 33 of a take-up device.

An den Stirnseiten 34 der Leimauftragswalze 17 ist jeweils ein radial über die zylindrische Oberfläche 35 der Leimauftragswalze 17 vorstehender Auflaufring 36 beziehungsweise 37 angeordnet. Der Abstand a der beiden Anlaufringe 36, 37 von einander parallel zur Achse 8 ist größer als die achsparallele Erstreckung b der Riffelung 11. Die Anordnung der Anlaufringe 36, 37 ist also derart, dass sie mit der Riffelung 11 der oberen Riffelwalze 5 nicht in Kontakt kommen können. Beiderseits der Riffelung 11 der oberen Riffelwalze 5 sind Stützringe 38, 39 auf der oberen Riffelwalze 5 angebracht, deren mittlerer Abstand c voneinander etwa dem Abstand a entspricht, sodass bei einer Bewegung der Leimauftragswalze 17 gegen die obere Riffelwalze 5 die Anlaufringe 36, 37 zur Anlage gegen die Stützringe 38 beziehungsweise 39 kommen, wobei zwischen der zylindrischen Oberfläche 35 der Leimauftragswalze 17 und der Riffelung 11 der oberen Riffelwalze 5 ein deutlich vergrößert dargestellter Spalt 40 mit einer Spaltweite d verbleibt, die geringer als die geringste Dicke von 0,08 mm des auf der Maschine für die Papierbahn 27 einsetzbaren Papiers ist. Für die Spaltweite d gilt 0,06 mm ≤ d ≤ 0,12 mm. Die Paare von Anlaufring 36 beziehungsweise 37 und Stützringen 38, 39 bilden also Abstandshalter 41, 42.On the end faces 34 of the glue application roller 17, a respective radially above the cylindrical surface 35 of the glue applicator roll 17 projecting casserole ring 36 and 37, respectively. The distance a of the two stop rings 36, 37 from each other parallel to the axis 8 is greater than the axis-parallel extension b of the corrugation 11. The arrangement of the stop rings 36, 37 is thus such that they are not in contact with the corrugation 11 of the upper corrugating roller 5 can come. On both sides of the corrugation 11 of the upper corrugating roll 5 support rings 38, 39 are mounted on the upper corrugating roll 5, the average distance c from each other approximately equal to the distance a, so that upon movement of the glue applicator roll 17 against the upper corrugating roll 5, the thrust rings 36, 37 for conditioning against the support rings 38 and 39 come, wherein between the cylindrical surface 35 of the glue applicator roll 17 and the corrugation 11 of the upper corrugating roll 5 remains a significantly enlarged gap 40 remains with a gap width d less than the smallest thickness of 0.08 mm of the machine for the paper web 27 is usable paper. For the gap width d, 0.06 mm ≤ d ≤ 0.12 mm applies. The pairs of thrust ring 36 and 37 and support rings 38, 39 thus form spacers 41, 42nd

Gegen die Stützringe 38, 39 liegt jeweils ein im Maschinengestell 1 festgelegter Schaber 43 an, der die zylindrische Oberfläche, das heißt die Stützfläche 44, gegen die die Anlaufringe 36 beziehungsweise 37 anlaufen können, von Verschmutzungen durch Leim, Papierfasern und dergleichen reinigt.Against the support rings 38, 39 is in each case a defined in the machine frame 1 scraper 43 which cleans the cylindrical surface, that is, the support surface 44 against which the thrust rings 36 and 37 can start from contamination by glue, paper fibers and the like.

Die aus besonders verschleißfestem Werkstoff bestehenden Stützringe 38, 39 sind - wie Fig. 2 erkennen lässt - auswechselbar auf der Riffelwalze 5 angeordnet.The existing wear-resistant material support rings 38, 39 are - like Fig. 2 can recognize - arranged interchangeable on the corrugating roller 5.

Das Ausführungsbeispiel nach den Fig. 1 und 3 unterscheidet sich von dem nach den Fig. 1 und 2 im Wesentlichen nur dadurch, dass die Anlaufringe 36', 37' radial weiter über die zylindrische Oberfläche 35 der Leimauftragswalze 17 vorstehen. Sie wirken direkt mit an der oberen Riffelwalze 5 seitlich von deren Riffelung 11 ausgebildeten Stützflächen 44' zusammen und bilden hiermit Abstandshalter 41', 42'. Gegen die Stützflächen 44' liegen ebenfalls Schaber 43 an. Auch bei dieser Ausgestaltung wird ein Sicherheitsspalt 40 gewährleistet, wenn die Leimauftragswalze 17 beispielsweise bei einem Riss der Papierbahn 27 gegen die Riffelung 11 anlaufen könnte, was aufgrund der Wirkung der Andrückeinrichtung 21 geschehen könnte.The embodiment of the Fig. 1 and 3 different from that after the Fig. 1 and 2 essentially only in that the stop rings 36 ', 37' protrude radially further beyond the cylindrical surface 35 of the glue application roller 17. They act directly on the upper corrugating roll 5 laterally formed by the corrugation 11 support surfaces 44 'together and thus form spacers 41', 42 '. Scrapers 43 are also located against the support surfaces 44 '. Also in this embodiment, a safety gap 40 is ensured when the glue application roller 17, for example, start at a crack of the paper web 27 against the corrugation 11 could, what could happen due to the action of the pressing 21.
