Description

Die Neuerung bezieht sich auf eine einseitige Wellpappenmaschine mit einem Maschinengestell, einer oberen und einer unteren Riffelwalze sowie einer mit der unteren Riffelwalze zusammenwirkenden Preßwalze, die an Hebelarmen am Maschinengestell schwenkbar gelagert ist, den Hebelarmen zugeordneten verstellbaren Anschlägen am Maschinengestell, und mit sich am Maschinengestell abstützenden mit den Hebelarmen zusammenwirkenden Verstellvorrichtungen, die zur Einstellung des Preßwalzenspalts die Hebelarme gegen die Anschlagflächen drücken.The innovation relates to a single-sided corrugated cardboard machine with a machine frame, an upper and a lower corrugating roller as well as a press roller that interacts with the lower corrugating roller, which is pivotably mounted on lever arms on the machine frame, adjustable stops assigned to the lever arms on the machine frame, and with supports on the machine frame with the lever arms interacting adjusting devices that press the lever arms against the stop surfaces to adjust the press nip.

Derartige einseitige Wellpappenmaschinen sind seit langem bekannt. Die untere Riffelwalze ist bezüglich ihrer Drehachse fest im Maschinengestell gelagert, während die obere Riffelwalze an Hebelarmen drehbar gelagert ist, die mit Hilfe einer Pneumatik- oder Hydraulikvorrichtung gegen die untere Riffelwalze angedrückt wird. Die Preßwalze ist ebenfalls an Hebelarmen drehbar gelagert. Die Preßwalze kann jedoch nicht ohne weiteres gegen die untere Riffelwalze angedrückt werden da dies einen sogenannten Stolperlauf bewirken würde durch das Ablaufen der Riffelung der Riffelwalze an der zylindrischen Preßwalze. Zu diesem Zweck sind am Maschinengestell Anschläge vorgesehen, welche die Bewegung der Preßwalze auf die untere Riffelwalze zu begrenzen. Die Anschläge sind verstellbar, um die Spaltbreite an die Papierdicke anzupassen. Mit Hilfe einer hydraulischen oder pneumatischen Andrückvorrichtung werden die über den Lagerpunkt der Preßwalze hinaus verlängerten Hebel in Richtung untere Riffelwalze gedrückt.Such single-sided corrugated cardboard machines have been known for a long time. The lower corrugated roller is fixed with respect to its axis of rotation in the machine frame, while the upper Corrugated roller is rotatably mounted on lever arms, which is pressed against the lower corrugated roller by means of a pneumatic or hydraulic device. The press roll is also rotatably mounted on lever arms. However, the press roller cannot be pressed easily against the lower corrugating roller, since this would cause a so-called trip over by the corrugation of the corrugating roller on the cylindrical press roller. For this purpose, stops are provided on the machine frame, which limit the movement of the press roll to the lower corrugated roll. The stops are adjustable to adapt the gap width to the paper thickness. With the help of a hydraulic or pneumatic pressing device, the levers extended beyond the bearing point of the press roll are pressed in the direction of the lower corrugating roll.

Die bekannte Konstruktion ist jedoch mit gewissen Nachteilen behaftet. Die Andrückvorrichtung muß den Hebel fest gegen die Anschläge drücken, so daß auch bei größeren Kräften im Walzenspalt dieser nicht vergrößert wird. Zu diesem Zweck ist eine für hohe Kräfte ausgelegte Andrückvorrichtung erforderlich. Auch wenn sie von hydraulischen Druckzylindern gebildet wird, ist eine gewisse Nachgiebigkeit nicht zu vermeiden. Es besteht daher die Gefahr eines gewissen Schwingens der Hebelarme in Abhängigkeit von unterschiedlich im Walzenspalt auftretenden Kräften. Ein derartiges Schwingen ist jedoch aus mehreren Gründen unerwünscht. Es kann die Qualität des Papiers beeinträchtigen. Ferner entstehen erhebliche Geräusche. Auch die Standzeit der Walzen wird hiervon negativ beeinflußt. Schließlich kärnen bei größeren Kräften die die Preßwalzen lagernden Hebel eine gewisse Durchbiegung -erfahren, wodurch die Genauigkeit des Walzenspaltes beeinträchtigt wird.However, the known construction has certain disadvantages. The pressing device must press the lever firmly against the stops, so that even with greater forces in the nip it is not enlarged. For this purpose, a pressing device designed for high forces is required. Even if it is formed by hydraulic pressure cylinders, a certain degree of flexibility cannot be avoided. There is therefore a risk of a certain swinging of the lever arms depending on the forces occurring differently in the roller gap. Such swinging is undesirable for several reasons. It can affect the quality of the paper. Furthermore ent there are significant noises. The service life of the rollers is also negatively affected. Finally, with greater forces, the levers supporting the press rolls experience a certain amount of deflection, as a result of which the accuracy of the roll gap is impaired.

Der Neuerung liegt die Aufgabe zugrunde, derartigen Nachteilen zu begegnen und insbesondere eine Lagerung der Preßwalze zu schaffen, die einen besonders ruhigen Lauf der Preßwalze ermöglicht.The innovation is based on the task of countering such disadvantages and, in particular, of creating a bearing for the press roll which enables the press roll to run particularly smoothly.

Diese Aufgabe wird neuerungsgemäß dadurch gelöst, daß die Anschlagflächen dem Preßwalzenspalt zugewandt angeordnet sind und die Bewegung der Hebelarme vom Preßwalzenspalt fort begrenzen.According to the innovation, this object is achieved in that the stop faces are arranged facing the press roll nip and limit the movement of the lever arms away from the press roll nip.

Bei der neuerungsgemäßen einseitigen Wellpappenmaschine werden die Hebelarme der Preßwalze nicht gegen einen Anschlag gedrückt, der die Bewegung der Preßwalze in Richtung Riffelwalze begrenzt. Vielmehr weisen die Anschlagflächen in umgekehrte Richtung,d.h.sie begrenzen die Bewegung der Preßwalze von der Riffelwalze fort. Die Begrenzung des Walzenspaltes erfolgt mithin über eine starre mechanische Verbindung. Es hat sich gezeigt, daß eine derartige Anordnung zu einem weitaus ruhigeren Lauf der Preßwalze führt als bei bekannten Maschinen, bei denen in Richtung von der unteren Riffelwalze fort wirkende Kräfte von einer Hydraulik- oder Pneumatikvorrichtung aufgefangen werden müssen.In the new one-sided corrugated cardboard machine, the lever arms of the press roll are not pressed against a stop which limits the movement of the press roll in the direction of the corrugated roll. Rather, the stop surfaces face in the opposite direction, ie they limit the movement of the press roll away from the corrugating roll. The roller gap is therefore limited by a rigid mechanical connection. It has been shown that such an arrangement leads to a much quieter running of the press roll than in known machines in which forces acting in the direction away from the lower corrugating roll are absorbed by a hydraulic or pneumatic device Need to become.

Der erzielbare ruhige Lauf der Preßwalze macht sich positiv auf die Qualität der Wellpappe bemerkbar. Ein weiterer Vorteil liegt darin, daß nur eine geringe Kraft aufgewendet werden muß, um die Hebelarme gegen die zugeordneten Anschläge zu halten. Die Verstellvorrichtungen dienen daher lediglich dazu, zu verhindern, daß die Hebelarme von den Anschlägen abheben. Dies ist jedoch normalerweise ohnehin nicht der Fall, da die Hebelarme unter ihrem Eigengewicht bzw. dem Gewicht der Preßwalze auf den Anschlägen ruhen. Bei der bekannten Maschine muß die Verstellvorrichtung dieses Gewicht überwinden, um den Hebelarm fest gegen die Anschläge zu halten.The attainable smooth running of the press roll has a positive effect on the quality of the corrugated cardboard. Another advantage is that only a small force has to be applied to hold the lever arms against the associated stops. The adjustment devices therefore only serve to prevent the lever arms from lifting off the stops. However, this is normally not the case anyway, since the lever arms rest on the stops under their own weight or the weight of the press roller. In the known machine, the adjusting device has to overcome this weight in order to hold the lever arm firmly against the stops.

Nach einer Ausgestaltung der Neuerung ist die Verstellvorrichtung vorzugsweise eine Zugvorrichtung. Sie kann beispielsweise von hydraulischen Zylindern gebildet werden.According to an embodiment of the innovation, the adjusting device is preferably a pulling device. For example, it can be formed by hydraulic cylinders.

Um gleichwohl bei sehr großen Kräften im Walzenspalt eine gewisse Nachgiebigkeit zu erzielen, stützen sich nach einer weiteren Ausgestaltung der Neuerung die Anschläge auf einer steifen Federvorrichtung ab. Die Federvorrichtung kann zum Beispiel von Tellerfederpaketen gebildet werden, die zum Beispiel nachgeben, wenn doppelte Papierlagen durch den Walzenspalt laufen.In order to nevertheless achieve a certain degree of flexibility in the case of very large forces in the roll gap, the stops are supported on a rigid spring device according to a further embodiment of the innovation. The spring device can be formed, for example, by plate spring assemblies, which give way, for example, when double layers of paper run through the nip.

Wie bereits erwähnt, bestimmt die Lage der Anschläge die Größe des Walzenspaltes. Da dieser entsprechend den Papierdicken. geändert werden muß, sieht eine Ausgestaltung der Neuerung vor, daß die Anschläge von Keilen gebildet sind, die gemeinsam auf einer Verstellwelle angeordnet sind und mit Schrägflächen der Hebel zusammenwirken. Die Verstellwelle kann zum Beispiel motorisch angetrieben und mit einem Geber versehen sein, der mit einer automatischen Prozeßsteuerung zusammenwirken kann. Mit Hilfe einer derartigen Verstellung der Anschläge können die Hebel auch einzeln eingestellt werden,was sich als vorteilhaft erwiesen hat.As already mentioned, the position of the stops determines the size of the nip. Since this corresponds to the paper thickness. must be changed, an embodiment of the innovation provides that the stops are formed by wedges, which are arranged together on an adjusting shaft and interact with inclined surfaces of the levers. The adjusting shaft can, for example, be motor-driven and provided with an encoder that can interact with an automatic process control. With such an adjustment of the stops, the levers can also be adjusted individually, which has proven to be advantageous.

Die Neuerung wird nachfolgend anhand von Zeichnungen näher erläutert.The innovation is explained in more detail below with the aid of drawings.

  • Fig. 1 zeigt in Seitenansicht eine einseitige Wellpappenmaschine.Fig. 1 shows a side view of a single-sided corrugated cardboard machine.
  • Fig. 2 zeigt einen Schnitt durch die Darstellung nach Fig. 1 entlang der Linie 2-2.FIG. 2 shows a section through the representation according to FIG. 1 along the line 2-2.

Bevor auf die in den Zeichnungen dargestellten Einzelheiten näher eingegangen wird,sei vorangestellt, daß jedes der beschriebenen Merkmale für sich oder in Verbindung mit Merkmalen der Ansprüche von neuerungswesentlicher Bedeutung ist.Before going into the details shown in the drawings, it should be assumed that each of the described features is of essential importance for innovation either alone or in conjunction with features of the claims.

Die Zeichnungen sind äußerst schemahaft und nicht maßstäblich.The drawings are extremely schematic and not to scale.

Das Maschinengestell einer einseitigen Wellpappenmaschine ist allgemein mit 10 bezeichnet. An Hebeln, von denen einer bei 11 dargestellt ist, ist eine obere Riffelwalze 12 gelagert.The machine frame of a single-sided corrugated cardboard machine is generally designated 10. An upper corrugated roller 12 is mounted on levers, one of which is shown at 11.

An einer Konsole 13 wird eine untere Riffelwalze 14 drehbar gelagert, die mit der oberen Riffelwalze 12 in bekannter Weise zusammenwirkt. Mit der unteren Riffelwalze l4 wirkt auch in bekannter Weise ein Auftragwerk 15 für Leim zusammen. Der über den Drehpunkt der oberen Riffelwalze 12 hinausgehende Abschnitt des Hebels 11 ist mit einem Hydraulikzylinder 16 verbunden. Dadurch kann die Riffelwalze 12 gegen die Riffelwalze 14 angedrückt werden.A lower corrugating roller 14 is rotatably mounted on a bracket 13 and cooperates with the upper corrugating roller 12 in a known manner. An application unit 15 for glue also interacts with the lower corrugating roller 14 in a known manner. The section of the lever 11 which extends beyond the pivot point of the upper corrugating roller 12 is connected to a hydraulic cylinder 16. As a result, the corrugating roller 12 can be pressed against the corrugating roller 14.

Mit Hilfe von Hebelarmen, von denen einer bei 17 dargestellt ist, ist eine Preßwalze 18 drehbar im Maschinengestell gelagert Der Hebel 17 ist schwenkbar im Maschinengestell 10 gelagert, wie bei 19 dargestellt. Der Schwenkpunkt des Hebels 11 für die obere Riffelwalze 12 ist im übrigen mit 20 bezeichnet.With the aid of lever arms, one of which is shown at 17, a press roller 18 is rotatably mounted in the machine frame. The lever 17 is pivotally mounted in the machine frame 10, as shown at 19. The pivot point of the lever 11 for the upper corrugated roller 12 is otherwise designated 20.

Der über den Drehpunkt der Preßwalze 18 hinausgehende Abschnitt des Hebels 17 ist an einem Hydraulikzylinder 21 angelenkt, der am anderen Ende am Maschinengestell 10 angelenkt ist. Auf der der unteren Riffelwalze 14 abgekehrten Seite des Hebels 17 ist eine Anschlagfläche 22 vorgesehen.The section of the lever 17 which extends beyond the pivot point of the press roll 18 is articulated on a hydraulic cylinder 21 which is articulated on the machine frame 10 at the other end. A stop surface 22 is provided on the side of the lever 17 facing away from the lower corrugating roller 14.

Sie wirkt mit einem Anschlag 23 zusammen, der sich am Maschinengestell 10 abstützt. Der Verstellzylinder 21 dient dazu, den Hebel 17 gegen den Anschlag 23 zu halten. Ohne entgegenwirkende Kräfte liegt der Hebel 17 durch sein Eigengewicht bzw. das Gewicht der Preßwalze 18 am Anschlag 23. Lediglich bei gewissen Erschütterungen könnte ein gewisses Anheben des Hebels 17 vom Anschlag 23 auftreten. Dies wird durch den Verstellzylinder 21 verhindert.It interacts with a stop 23, which is supported on the machine frame 10. The adjusting cylinder 21 serves to hold the lever 17 against the stop 23. The lever 17 lies by its own without opposing forces weight or the weight of the press roller 18 at the stop 23. Only with certain vibrations could the lever 17 be lifted from the stop 23 to a certain extent. This is prevented by the adjusting cylinder 21.

Wie aus Fig. 2 zu erkennen, wird der Anschlag 23 von zwei Keilen 24, 25, die sich an einer Anschlagfläche 26 des Maschinengestells 10 abstützen, gebildet. Auf der gegenüberliegenden Seite haben sie eine Schrägfläche, die mit schrägen Anschlagflächen 27, 28 des Hebels 17 zusammenwirken. Die Anschlagflächen 27, 28 am Hebel konvergieren zur Mitte. Durch Aufeinanderzubewegen der Keile 24, 25 wird mithin der Hebel in Richtung untere Riffelwalze 14 verstellt. In umgekehrter Richtung wird der Hebel 17 von der Riffelwalze 14 fort verstellt.Die Keile 24,25 sitzen auf Links-und Rechtsgewindeabschnitten einer Verstellwelle 29, die von einem Motor 30 über ein Getriebe 31 angetrieben werden kann. An der Getriebewelle 32 ist ferner ein Meßwertgeber 33 angebracht. Mit Hilfe einer automatischen Steuerung kann die jeweilige Position der Keile 24, 25 eingestellt werden. Der Meßwertgeber 33 gibt die jeweilige Position der Welle 29 und damit der Keile 24, 25 wieder. Deren Position bestimmt die Spaltbreite. Diese kann z.B. durch Ableitung vom Meßwertgebersignal digital angezeigt werden.As can be seen from FIG. 2, the stop 23 is formed by two wedges 24, 25, which are supported on a stop surface 26 of the machine frame 10. On the opposite side they have an inclined surface which cooperate with inclined stop surfaces 27, 28 of the lever 17. The stop surfaces 27, 28 on the lever converge towards the center. By moving the wedges 24, 25 towards one another, the lever is thus adjusted in the direction of the lower corrugated roller 14. In the opposite direction, the lever 17 is moved away from the corrugating roller 14. The wedges 24, 25 sit on left and right-hand thread sections of an adjusting shaft 29, which can be driven by a motor 30 via a gear 31. A transmitter 33 is also attached to the gear shaft 32. With the help of an automatic control, the respective position of the wedges 24, 25 can be set. The sensor 33 shows the respective position of the shaft 29 and thus the wedges 24, 25 again. Their position determines the gap width. This can e.g. are displayed digitally by derivation from the transmitter signal.

Es sei noch erwähnt, daß die Anlagekraft des Hebels 17 am Anschlag 23 noch durch den Papierzug vergrößert wird. Bei bekannten Maschinen kann unter Umständen der Papierzug so stark sein, daß es zu einer vorübergehenden Verstellung der Hebelarme von den Anschlägen fort kommt mit der Folge einer vorübergehenden Vergrößerung des Walzenspaltes.It should also be mentioned that the contact force of the lever 17 at the stop 23 is increased by the paper pull. At In known machines, the paper draw can be so strong that there is a temporary adjustment of the lever arms away from the stops, with the result of a temporary enlargement of the nip.
