Abstract

1. A one-sided corrugated cardboard machine having an upper and a lower corrugated roll for corrugating a corrugation material, especially of paper or cardboard, as well as a pressure roll associated with the lower corrugated roll for connecting the corrugated web to a covering web, with the corrugation of both corrugated rolls being shaped essentially identically and the corrugation peak of the corrugated rolls being formed with a radius which is smaller than the radius of the corrugated ground, characterized in that the flank (13) between the corrugation peak (11) and the corrugation ground (12) is offset backwards vis-à-vis the common tangent of the circular arcs of corrugation peak and corrugation ground and in that the radius of the corrugation ground (12) is greater than that of the corrugation ground (12) essentially only by the thickness of the corrugated material web.

Description

Die Neuerung bezieht sich auf eine einseitige Wellpappenmaschine mit einer oberen und einer unteren Riffelwalze zur Riffelung eines Wellenstoffes, insbesondere aus Papier oder Pappe, sowie einer der unteren Riffelwalze zugeordneten Preßwalze zur Verbindung der gewellten Bahn mit einer Deckbahn, wobei der Riffelgrund der Riffelwalzen einen Radius aufweist, der um mindestens die Dicke der Wellstoffbahn größer als der Radius der Riffelspitze ist.The innovation relates to a single-sided corrugated cardboard machine with an upper and a lower corrugating roller for corrugating a corrugated material, in particular made of paper or cardboard, and a press roller assigned to the lower corrugating roller for connecting the corrugated web to a cover sheet, the corrugating base of the corrugating rollers having a radius which is larger than the radius of the corrugated tip by at least the thickness of the corrugated material web.

Die Riffelprofile derartiger Riffelwalzen werden in fünf Gruppen A, B, C, D und E unterteilt, die sich nach Zahnteilung und Profilhöhe unterscheiden. Spitze und Grund des Riffelprofils sind im Querschnitt kreisförmig, während die Flanke tangential an den Kreisbögen liegt.The corrugated profiles of such corrugated rollers are divided into five groups A, B, C, D and E, which differ according to tooth pitch and profile height. The top and bottom of the corrugated profile are circular in cross-section, while the Flank is tangent to the arcs.

Die Formung der Wellung erfolgt bekanntlich zwischen der Riffelspitze der einen Riffelwalze und dem Riffelgrund der Gegenwalze. Aus diesem Grunde muß der Grundradius mindestens um die Dicke des Wellstoffes, also zum Beispiel einer Papierbahn, gegenüber dem Spitzenradius größer sein, damit eine einwandfreie Prägung des Wellenstoffes stattfinden kann.As is known, the corrugation is formed between the corrugated tip of one corrugated roller and the corrugated base of the counter roller. For this reason, the base radius must be greater than the tip radius by at least the thickness of the corrugated material, for example a paper web, so that the corrugated material can be embossed properly.

Bei diesem Prägevorgang erfolgt ein erheblicher Verschleiß der Riffelspitzen, vor allem infolge der Relativbewegung zwischen Riffelspitze und Wellstoffbahn. Auch die Belastung des vorher durch Wärme und/oder Feuchtigkeit behandelten Wellstoffes ist ganz erheblich. Ein Verschleiß der Riffelspitzen führt zwangsläufig zu einem größeren Spitzenradius mit der Folge, daß allmählich eine Klemmung zwischen den Profilen der zusammenwirkenden Riffelwalzen eintritt. Ein wirksames Prägen von Wellen in der Wellstoffbahn kann dann nicht mehr stattfinden. Ein Klemmen des Wellenstoffes im Riffelprofil führt ferner dazu, daß er infolge der Umschlingungsreibung im Riffellabyrinth überbeansprucht wird. Dadurch entsteht die Gefahr eines Wellenbruches. Die wesentlichen Qualitätsmerkmale der Pappe, wie Flachstauchdruck und Stapelstauchdruck sinken.This embossing process results in considerable wear on the corrugated tips, primarily as a result of the relative movement between the corrugated tip and the corrugated material web. The load on the corrugated material previously treated by heat and / or moisture is also very considerable. Wear of the corrugated tips inevitably leads to a larger tip radius, with the result that a gradual clamping between the profiles of the interacting corrugated rollers occurs. An effective embossing of waves in the corrugated material web can then no longer take place. A jamming of the corrugated material in the corrugated profile also leads to it being overstressed due to the wrap friction in the corrugated labyrinth. This creates the risk of a wave breaking. The main quality characteristics of the cardboard, such as flat upsetting and stacking upsets, decrease.

Es ist bekannt, einem vorzeitigen Klemmen durch einen größeren Unterschied zwischen Grundradius und Spitzenradius zu begegnen. Eine Mitnähme der oberen Riffelwalze durch die untere kann jedoch naturgemäß dann nicht mehr so präzise erfolgen wie das der Fall ist, wenn der Spitzenradius nur um den Betrag der Wellstoffdicke geringer ist als der Radius des Riffelgrundes. Die nicht mehr saubere Mitnahme der mitgenommenen Riffelwalze führt zu dem Nachteil, daß der Verschleiß an der Spitze nicht mehr symmetrisch stattfindet, was dann zu asymmetrischen Wellenausprägungen führt und damit zu einer Minderung der Pappenqualität.It is known to counter premature clamping by a greater difference between the base radius and the tip radius. Of course, the upper corrugating roller can no longer be taken along by the lower one as precisely as is the case if the tip radius is only smaller by the amount of the corrugated material thickness than the radius of the corrugating base. The no longer clean entrainment of the corrugated roller entrained leads to the disadvantage that the wear at the tip no longer takes place symmetrically, which then leads to asymmetrical corrugations and thus to a reduction in the cardboard quality.

Der Neuerung liegt die Aufgabe zugrunde, eine einseitige Wellpappenmaschine zu schaffen, bei der trotz eines Verschleißes des Riffelprofils der Riffelwalzen eine einwandfreie Qualität der geformten Wellstoffbahn sichergestellt werden kann.The innovation is based on the task of creating a one-sided corrugated cardboard machine in which, despite wear of the corrugated profile of the corrugated rollers, a perfect quality of the shaped corrugated material web can be ensured.

Diese Aufgabe wird neuerungsgemäß dadurch gelöst, daß die Flanke zwischen Riffelspitze und.Riffelgrund gegenüber der gemeinsamen Tangente an den Kreisbögen von Riffelspitze und Riffelgrund zurückversetzt liegt.According to the innovation, this object is achieved in that the flank between the Riffelspitze and Riffelgrund is set back from the common tangent to the arcs of the Riffelspitze and Riffelgrund.

Bei der Neuerung ist erkannt worden, daß der Nachteil der Wellenausformung bei herkömmlichen Vellpappenmaschinen dadurch eintritt, daß der zwangsläufige Verschleiß, vor allem an der Riffelspitze, zu einem Quetschen des Wellstoffes an den Flanken zwischen Riffelspitze und Riffelgrund führt. Dadurch wird das Material im Flankenbereich gequetscht und gerieben, mit der Gefahr, daß die Struktur der Wellstoffbahn so beeinträchtigt wird, daß die,Qualität entscheidend beeinträchtigt ist. Im eigentlichen Formungsbereich zwischen Riffelspitze und Riffelgrund findet hingegen eine ausreichende Prägung nicht mehr statt. Bei der neuerungsgemäßen Wellpappenmaschine auch bei einem erheblichen Verschleiß des Riffelspitzenprofils der unerwünschte Klemmeffekt nicht eintreten, da zwischen den jeweils zusammenwirkenden Flanken der Profile der beiden Riffelwalzen ausreichend Freiraum vorhanden ist, um auch bei einem starken Abtrag der Riffelspitzen keinen Formungseffekt auf die Wellstoffbahn auszuüben. Dieser geschilderte Vorteil bleibt auch nach einem Profilhöhenverschleiß von mehreren Zehntel-Millimetern vollständig erhalten.With the innovation it has been recognized that the disadvantage of shaft shaping in conventional corrugated cardboard machines arises in that the inevitable wear, especially on the corrugated tip, leads to squeezing of the corrugated material on the flanks between corrugated tip and corrugated base. This squeezes the material in the flank area and grated, with the risk that the structure of the corrugated material web is impaired in such a way that the quality is decisively impaired. In contrast, there is no longer sufficient embossing in the actual forming area between the corrugated tip and the corrugated base. In the corrugated cardboard machine according to the innovation, even if there is considerable wear on the corrugated tip profile, the undesirable clamping effect does not occur, since there is sufficient space between the respective flanks of the profiles of the two corrugated rollers so that even if the corrugated tips are severely removed, there is no shaping effect on the corrugated material web. This described advantage is fully retained even after a profile height wear of several tenths of a millimeter.

Bei der neuerungsgemäßen Wellpappenmaschine findet mithin eine wirksame Prägung im wesentlichen nur im Bereich Spitze/Grund statt. Es hat sich herausgestellt, daß sowohl die Qualität der erzielbaren Wellung als auch deren Belastbarkeit erheblich erhöht werden. So sind die Hoch-/Tiefwerte der erzielbaren Wellpappe (die Wellenhöhenunterschiede) erheblich geringer als bei herkömmlichen Wellpappenmaschinen. Die verbesserten Hoch-/Tiefwerte ermöglichen auch eine wirksamere Verklebung der zweiten Decke.In the corrugated cardboard machine according to the invention, effective embossing therefore takes place essentially only in the area of the tip / bottom. It has been found that both the quality of the corrugation that can be achieved and its resilience are considerably increased. The high / low values of the corrugated cardboard that can be achieved (the height differences) are considerably lower than with conventional corrugated cardboard machines. The improved high / low values also enable more effective bonding of the second ceiling.

Bei der herkömmlichen Wellpappenmaschine bestehen auch Probleme hinsichtlich der Papierdicke, welche aufgrund unterschiedlicher Grammaturen nach Art der Herstellung und Papierzusammensetzung erheblich schwanken können.Bei herkömmlichen Wellpappenmaschinen führt z.B. eine unzulässig große Dicke wieder zu dem unerwünschten Quetschen und damit zur Beeinträchtigung der Papierqualität. Bei der neuerungsgemäßen Wellpappenmaschine ist hingegen eine erhöhte Dicke oder eine unterschiedliche Dicke ohne Belang, weil im Flankenbereich eine Quetschung in keinem Falle eintreten kann.In the conventional corrugated cardboard machine there are also problems with the paper thickness, which are due to different Grammages can vary considerably depending on the type of production and the composition of the paper. In the case of the corrugated cardboard machine according to the innovation, on the other hand, an increased thickness or a different thickness is irrelevant, because in the flank area there can be no crushing in any case.

In welcher Form die .Flankenflächen bei den Riffelwalzen der neuerungsgemäßen Wellpappenmaschine ausgeführt werden, ist von ihrer Auswirkung auf den Prägevorgang gleich, solange der erwähnte Versatz bzw. der ausreichende Abstand jeweils zusammenwirkender Flanken gewährleistet ist. Von der Fertigung der Riffelwalzen her wird vorzugsweise ein einfaches Flankenprofil gewählt, beispielsweise eine gerade Flanke. In diesem Zusammenhang sieht eine Ausgestaltung der Neuerung vor, daß die Flanke tangential zum Kreisbogen des Riffelgrundes liegt, den Kreisbogen der Riffelspitze hingegen schneidet. In einer weiteren Ausgestaltung der Neuerung ist hierzu vorgesehen, daß die Riffelspitze annähernd von einem Halbkreis gebildet ist und die Flanke sich an das zugeordnete Ende des Halbkreises anschließt. Dadurch ergibt sich zwar ein unstetiger Übergang zwischen Flanke und Bogen der Riffelspitze, für den Prägevorgang spielt dies indessen keine Rolle. Aus fertigungstechnischen Gründen ist es jedoch vorteilhaft, wenn nach einer weiteren Ausgestaltung der Neuerung ein bogenförmiger Übergang von der Flanke zum Kreisbogen der Riffelspitze erfolgt.The shape of the flank surfaces in the corrugated rolls of the corrugated cardboard machine according to the invention has the same effect on the embossing process, as long as the mentioned offset or the sufficient distance between the respective flanks is guaranteed. A simple flank profile, for example a straight flank, is preferably selected from the manufacture of the corrugated rollers. In this context, an embodiment of the innovation provides that the flank lies tangential to the circular arc of the base of the corrugated base, but intersects the circular arc of the corrugated tip. In a further embodiment of the innovation, it is provided that the corrugated tip is formed approximately by a semicircle and the flank adjoins the assigned end of the semicircle. Although this results in a discontinuous transition between the flank and arc of the corrugated tip, this does not play a role in the embossing process. For manufacturing reasons, however, it is advantageous if, after a further configuration of the innovation, an arcuate transition from the flank to the circular arc of the Riffelspitze.

Während bei den Riffelwalzen herkömmlicher Wellpappenmaschinen der Radius der Riffelspitze über das Maß der Papierdecke kleiner gewählt wurde als der Radius des Riffelgrundes, sieht eine Ausgestaltung der Neuerung vor, daß der Radius des Riffelgrundes im wesentlichen um die Dicke des Wellstoffbogens größer als der der Riffelspitze ist. Dadurch ergibt sich ein formschlüssiges Ineinandergreifen von Riffelspitze und Riffelgrund und somit eine gleichmäßige Prägung einer Welle. Ferner wird die mitgenommene Riffelwalze ohne Spiel genommen, so daß ein asymmetrischer Verschleiß und mithin eine asymmetrische Wellenausprägung nicht eintritt.While in the corrugated rollers of conventional corrugated cardboard machines the radius of the corrugated tip was chosen to be smaller than the radius of the corrugated base over the size of the paper cover, an embodiment of the innovation provides that the radius of the corrugated base is substantially larger than that of the corrugated tip by the thickness of the corrugated sheet. This results in a positive interlocking of the corrugated tip and the corrugated base and thus a uniform embossing of a shaft. Furthermore, the corrugated roller that is carried along is taken without play, so that asymmetrical wear and thus an asymmetrical wave characteristic does not occur.

Ein Ausführungsbeispiel der Neuerung wird nachfolgend anhand einer Zeichnung näher erläutert.An embodiment of the innovation is explained in more detail below with reference to a drawing.

Die einzige Figur zeigt vergrößert das Profil einer Riffelwalze einer einseitigen Wellpappenmaschine nach der Neuerung.The only figure shows an enlarged profile of a corrugated roller of a single-sided corrugated cardboard machine after the innovation.

Bevor auf die in der Zeichnung dargestellten Einzelheiten eingegangen wird, sei vorangestellt, daß jedes der beschriebenen Teile für sich oder in Verbindung mit Merkmalen der Ansprüche von neuerungswesentlicher Bedeutung ist.Before going into the details shown in the drawing, it should be noted that each of the parts described is of importance for innovation, either individually or in conjunction with features of the claims.

Die einzige Figur zeigt einen Schnitt durch eine Riffelwalze bzw. von einem Teil des Riffelprofils. Die Riffelwalze ist allgemein mit 10 bezeichnet. Sie enthält Riffelspitzen 11 aus vollem Material, welche in gleiohmäßigen Abständen am Umfang der Riffelwalze angeordnet sind. Die Riffelteilung ist mit t bezeichnet. Zwischen jeweils zwei benachbarten Riffelspitzen befindet sich der Riffelgrund 12. Die Profilhöhe wird mit h bezächnet.The single figure shows a section through a corrugated roller or from part of the corrugated profile. The corrugated roller is generally designated 10. It contains corrugated tips 11 made of solid material, which are arranged at regular intervals on the circumference of the corrugated roller. The corrugation is marked with t. The Riffelgrund 12 is located between every two adjacent Riffel tips. The profile height is counted with h.

Die Riffelspitzen 11 haben einen Radius r5, der kleiner ist als der Radius r8 des Riffelgrundes, und zwar um den Betrag des zu formenden Papiers. Die Flanken 13 zwischen Riffelspitze 11 und Riffelgrund 12 werden von geraden Flächen gebildet, die tangential am Bogen des Riffelgrundes 12 verlaufen. Die Riffelspitzen sind halbkreisförmig im Querschnitt, und die geraden Flankenflächen sind mit dem Halbkreisbogen an dem Punkt verbunden, in dem der Durchmesser den Halbkreis schneidet, wie bei 14 dargestellt. Aus fertigungstechnischen Gründen kann der unstetige Übergang zwischen Flanke 13 und Kreisbogen der Riffelspitze 11 kontinuierlich geformt werden, wie durch die gestrichelte Linie 15 angedeutet.The corrugated tips 11 have a radius r5, which is smaller than the radius r8 of the corrugated base, by the amount of the paper to be formed. The flanks 13 between the corrugated tip 11 and the corrugated base 12 are formed by straight surfaces which run tangentially on the arc of the corrugated base 12. The corrugated tips are semicircular in cross section, and the straight flank surfaces are connected to the semicircular arc at the point where the diameter intersects the semicircle, as shown at 14. For technical reasons, the discontinuous transition between the flank 13 and the circular arc of the corrugated tip 11 can be formed continuously, as indicated by the dashed line 15.

Obere und untere Riffelwalze einer einseitigen Wellpappenmaschine haben identisches Profil. Beim Eingriff der Riffespitzen 11 in den Nutgrund 12 bleiben mithin die Flanken 13 in einem merklichen Abstand voneinander. Auf die sich dazwischen befindliche Papierlage wird mithin in diesem Bereich ein Druck bzw. eine Kraft nicht ausgeübt. Die Prägung der Wellen erfolgt im wesentlichen zwischen Riffelspitze 11 und Riffelgrund 12, wodurch sich eine qualitativ hochwertige Wellung ergibt. Diese Qualität wird auch nicht dadurch beeinträchtigt, daß notwendigerweise die Riffelspitzen 11 mit der Zeit verschleißen und der Radius r5 etwas größer wird.The upper and lower corrugated rollers of a single-sided corrugated cardboard machine have an identical profile. When the reef tips 11 engage in the groove base 12, the flanks 13 therefore remain at a noticeable distance from one another. A pressure or a force is therefore not exerted on the paper layer in between in this area. The waves are embossed essentially between the corrugated tip 11 and Riffelgrund 12, which results in a high quality corrugation. This quality is also not affected by the fact that the corrugated tips 11 necessarily wear out over time and the radius r5 becomes somewhat larger.
