Description

Die Neuerung bezieht sich auf eine einseitige Wellpappenmaschine mit einer oberen und einer unteren Riffelwalze, einer der unteren Riffelwalze zugeordneten Preßwalze, einem sich im wesentlichen über die Breite der unteren Riffelwalze erstreckenden, an eine Vakuumquelle angeschlossenen Saugkasten, der auf der Seite der unteren Riffelwalze angeordnet ist, die von der Wellbahn nicht bedeckt ist, und der in ringförmigen Saugnuten der unteren Riffelwalze einen Unterdruck erzeugt, und Abdichtblechen, die auf der der Preßwalze zugekehrten Seite des Saugkastens in die Saugnuten eingreifen.The innovation relates to a single-sided corrugated cardboard machine with an upper and a lower corrugating roller, a press roller assigned to the lower corrugating roller, a suction box which extends essentially over the width of the lower corrugating roller and is connected to a vacuum source and is arranged on the side of the lower corrugating roller , which is not covered by the corrugated sheet, and which generates a negative pressure in annular suction grooves of the lower corrugating roller, and sealing plates which engage in the suction grooves on the side of the suction box facing the pressing roller.

Eine derartige einseitige Wellpappenmaschine ist bekannt (DE-PS 2 840 150). Die Abdichtbleche sind auf beide, Seiten mit dem Saugkasten verbunden und greife, in die Saugnutan ein. Eine derartige konstruktion ist jedoch mit etlichen Nachteilen behaftet.Such a one-sided corrugated cardboard machine is known (DE-PS 2 840 150). The sealing plates are connected on both sides to the suction box and engage in the suction groove. However, such a construction has a number of disadvantages.

Absaugkasten oder -haube mit dem Abdichtblechen überdecken den gesamtem zugeordneten Umfangsbereich der unteren Riffelwalze. Diese ist daher von außen völlig unzugänglich.Suction box or hood with the sealing plate cover the entire assigned peripheral area of the lower corrugated roller. It is therefore completely inaccessible from the outside.

Eine Riffelwalze unterliegt bekanntlich Längenänderungen durch Wärmedehnung. Die Abdichtbleche sollen nach Möglichkeit diese Wärmedehnungen mitmachen, andernfalls Gefahr besteht, daß sie am den Nutwänden schleifen, bzw. verbogen werden. Deshalb ist auch bekannt, den Absaugkasten mit Dampf zu beheizen, damit er die Wärmedehnungen mit vollzieht. Außer dem Nachteil des zusätzlichen Aufwande hierfür hat sich gezeigt, daß trotz der Beheizung eine ausreichende Anpassung am Wärmedehnungen der Riffelwalze insbesondere während der Aufheizphase nicht erzielt wird.As is known, a corrugated roller is subject to changes in length due to thermal expansion. The sealing plates should, if possible, take part in these thermal expansions, otherwise there is a risk that they will rub or be bent on the groove walls. That is why it is also known to heat the suction box with steam so that it also carries out the thermal expansion. In addition to the disadvantage of the additional effort for this, it has been shown that, despite the heating, adequate adaptation to the thermal expansion of the corrugated roller is not achieved, particularly during the heating phase.

Der Neuerung liegt die Aufgabe zugrunde, bei einer einen Saugkasten enthaltenden einseitigen Wellpappernmaschine diesen so auszubilden, daß etwa in Störungsfällen ein Zugang zur unteren Riffelhalze bzw. zum Spaltzwischen Saugkasten zur unterer Riffelwalze möglich ist.The innovation is based on the object in a one-sided corrugated cardboard machine containing a suction box to design it so that, for example, in the event of malfunctions, access to the lower corrugating roll or to the gap between the suction box to the lower corrugating roll is possible.

Diese Aufgabe wird neuerungsgemäß dadurch gelöst, daß im Maschinengestell ein Tragbalken für die Abdichtbleche gehalten ist, der getrennt vom Saugkasten angeordnet ist und der Saugkasten mit Hilfe einer Verstellvorrichtung über einen großen Weg verstellbar ist.According to the innovation, this object is achieved in that a supporting beam for the sealing plates is held in the machine frame, which is arranged separately from the suction box and the suction box can be adjusted over a long distance with the aid of an adjusting device.

Bei der neuerungsgemäßen Wellpappenmaschine sind die Abdichtbleche von einem Tragteil gehalten, das vom Saugkasten getrennt im Maschinengestell gehalten wird. Der Saugkasten, der einen beträchtlichen Teil des Umfangs der Riffelwalze überdeckt, kann daher ausreichend weit von der Riffelwalze entfernt werden, um einen guten Zugang zur Riffelwalze zu ermöglichen.In the corrugated cardboard machine according to the innovation, the sealing plates are held by a supporting part which is held separately from the suction box in the machine frame. The suction box, which covers a considerable part of the circumference of the corrugating roller, can therefore be removed far enough from the corrugating roller to allow good access to the corrugating roller.

Der Tragbalken für die Abdichtbleche ist vorzugsweise ebenfalls verstellbar, jedoch nur über eine begrenzte Strecke derart, daß die Abdichtbleche in den Saugnuten verbleiben. Eine derartige Verstellung ist zum Beispiel nötig, um beim sogenannten Wärmeschlag (unterschiedlich radiale Ausdehnung infolge Kondenswasser) ein Anschlagen zu verhindern.The support beam for the sealing plates is preferably also adjustable, but only over a limited distance in such a way that the sealing plates remain in the suction grooves. Such an adjustment is necessary, for example, to prevent striking during the so-called thermal shock (different radial expansion due to condensation water).

In einer Ausgestaltung der Neuerung ist vorgesehen, daß der Saugkasten über einen Anschlag mit dem Tragbalken so zusammenwirkt, daß bei einer Verstellung des Saugkastens in Richtung unterer Riffelwalze der Tragbalken gegen eine Federkraft mitgenommen wird und der Tragbalken über eine begrenzte Strecke von der unteren Riffelwalze abgehoben wird, wenn der Saugkasten von der unteren Riffelwalze fortbewegt wird derart, daß die Abdichtbleche noch in den Saugnuten verbleiben. DieIn one embodiment of the innovation, it is provided that the suction box interacts with the supporting beam via a stop such that when the suction box is adjusted in the direction of the lower corrugating roller, the supporting beam is carried against a spring force and the supporting beam is lifted from the lower corrugating roller over a limited distance when the suction box is moved away from the lower corrugating roller in such a way that the sealing plates still remain in the suction grooves. The

Bewegung des Tragbalkens erfolgt mithin zwischen zwei Anschlägen, wobei der obere Anschlag so liegt, daß die Abdichtbleche noch in den Saugnuten sitzen. Der andere Anschlag begrenzt die Tiefe der Abdichtbleche in den Saugnuten.Movement of the support beam therefore takes place between two stops, the upper stop being such that the sealing plates are still seated in the suction grooves. The other stop limits the depth of the sealing plates in the suction grooves.

In einer weiteren Ausgestaltung der Neuerung ist vorgesehen, daß die Abdichtbleche entlang einer Achse parallel zur Riffelwalzenachse verschiebbar im Tragbalken angeordnet sind. Auf diese Weise können die Abdichtbleche Wärmedehnungen ser unteren Riffelwalze und damit einer Verlagerung der Saugnut ohne weiteres folgen.In a further embodiment of the innovation it is provided that the sealing plates are arranged in the supporting beam so as to be displaceable along an axis parallel to the corrugating roller axis. In this way, the sealing plates thermal expansion ser lower corrugating roller and thus a displacement of the suction groove can easily follow.

Zwecks einfachen Einbaus und Ausbaus der Abdichtbleche sieht eine weitere Ausgestaltung der Neuerung vor, daß die Abdichtbleche einen hakenartigen oberen Abschnitt aufweisen, der in einen komplementären Abschnitt des Tragbalkens eingreift, und am Tragbalken eine durchgehende Schiene oder mehrere Schienenabschnitte von oben die Bewegung der Abdichtbleche in Richtung aus den Saugnuten begrenzen. Durch Verstellung der Schiene bzw. der Schienenabschnitte können die Abdichtbleche ohne weiteres in den Tragbalken eingehängt werden. Das Auswechseln einzelner Abdichtbleche, welche Verschleißteile darstellen, ist daher besonders einfach zu bewerkstelligen.For the purpose of simple installation and removal of the sealing plates, a further embodiment of the innovation provides that the sealing plates have a hook-like upper section which engages in a complementary section of the supporting beam, and on the supporting beam a continuous rail or several rail sections from above the movement of the sealing plates in the direction limit from the suction grooves. By adjusting the rail or the rail sections, the sealing plates can easily be hung in the supporting beam. The replacement of individual sealing plates, which are wearing parts, is therefore particularly easy to do.

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 schematisch in Seitenansicht eine einseitige Wellpappenmaschine nach der Neuerung. Bevor auf die in den Zeichnungen dargestellten Einzelheiten näher eingegangen wird, sei vorangestellt, daß jedes der beschriebenen Teile für sich oder in Verbindung mit Merkmalen der Ansprüche von neuerungswesentlicher Bedeutung sind.The single figure shows schematically a side view of a single-sided corrugated cardboard machine according to the innovation. Before going into the details shown in the drawings, it should be assumed that each of the parts described are of essential importance for innovation either individually or in conjunction with features of the claims.

Die zeichnierische Darstellung ist äußerst schemahaft und nicht maßstäblich. Insbesondere sind Tragbalken und Leitbleche im Verhältnis zur tatsächlichen Größe stark vergrößert gezeichnet.The drawing is extremely schematic and not to scale. In particular, the supporting beams and baffles are drawn in a greatly enlarged manner in relation to the actual size.

In der Zeichnung sind eine obere Riffelwalze 10, eine untere Riffelwalze 11 sowie eine Preßwalze 12 angedeutet, die in bekannter Weise zusammenwirken. Auf der Seite der unteren Riffelwalze 11, die nicht mit der Wellstoffbahn 13 zusammenwirkt, ist ein Saugkasten 14In the drawing, an upper corrugating roller 10, a lower corrugating roller 11 and a press roller 12 are indicated, which cooperate in a known manner. On the side of the lower corrugating roller 11, which does not interact with the corrugated web 13, there is a suction box 14

angeordnet mit einem Anschluß 15 für Vakuum. Der Saugkasten 14 ist an seiner der Riffelwalze 11 1 zugekehrten Seite deren Krümmung angepaßt. Die Riffelwalze 11 besitzt in axialen Abständen einige ringförmige Saugnuten 16, Über die Saugnuten 16 wird der Unterdruck im Saugkasten 14 auf die gegenüberliegende Seite übertragen, um die gewellte Bahn an der Riffelwalze 11 zu halten.arranged with a connection 15 for vacuum. The suction box 14 is adapted on its side facing the corrugated roller 11 1 whose curvature. The corrugated roller 11 has some annular suction grooves 16 at axial intervals. The vacuum in the suction box 14 is transmitted to the opposite side via the suction grooves 16 in order to hold the corrugated web on the corrugated roller 11.

Parallel zum Saugkasten 14 und annähernd über die Länge der unteren Riffelwalze 11 erstreckt sich ein Tragbalken 17 für Abdichtbleche 18. Jeder Saugnut 16 ist ein Abdichtblech 18 zugeordnet, die mit einem Abschnitt 19 die Saugnuten 16 ausfüllen. Die Abdichtbleche 18 haben eine Abstreiferfunktion. Ferner verhindern sie einen Ausgleich des Vakuums. Sie halten jedoch einen Abstand zum Nutgrund, um einen durchgehenden Kanal in den Saugnuten zu belassen. Die Abdichtbleche 18 besitzen einen oberen hakenförmigen Abschnitt 20, der mit einem hakenförmigen Abschnitt 21 am unteren Ende des Tragbalkens 17 zusammenwirkt. Man erkennt, daß die Abdichtbleche 13 relativ zum Tragbalken 17 verschiebbar sind. Diese Verschiebung ermöglicht eine Anpassung an unterschiedliche Wärmedehnungen der unteren Riffelwalze 11. Im Querschnitt 22 des Tragbalkens 17 am oberen Ende lagert eine oder mehrere Verstellschrauben 23, die mit einer Schiene 24 zusammenwirken, die eine obere Begrenzung für den hakenförmigen Abschnitt 20 der Abdichtbleche 18 darstellt. In der in der Zeichnung dargestellten Position sind die Abdichtbleche 18 sicher im Tragbalken 17 aufgenommen, können jedoch ihre beschriebene seitliche Bewegung ausführen.A support bar 17 for sealing plates 18 extends parallel to the suction box 14 and approximately over the length of the lower corrugating roller 11. Each suction groove 16 is assigned a sealing plate 18, which fill the suction grooves 16 with a section 19. The sealing plates 18 have a wiper function. They also prevent the vacuum from being equalized. However, you keep a distance from the bottom of the groove to leave a continuous channel in the suction grooves. The sealing plates 18 have an upper hook-shaped section 20 which interacts with a hook-shaped section 21 at the lower end of the supporting beam 17. It can be seen that the sealing plates 13 are displaceable relative to the supporting beam 17. This displacement enables adaptation to different thermal expansions of the lower corrugating roller 11. In the cross section 22 of the supporting beam 17 at the upper end there is one or more adjusting screws 23 which cooperate with a rail 24 which represents an upper limit for the hook-shaped section 20 of the sealing plates 18. In the position shown in the drawing, the sealing plates 18 are securely received in the supporting beam 17, but can perform the lateral movement described.

Der Saugkasten 14 besitzt auf der dem Tragbalken 17 zugekehrten Seite einen seitlichen Anschlag 25, der dichtend, wie bei 26 dargestellt, mit einem Ansatz 27 des Tragbalkens 17 zusammenwirkt. An der Unterseite sind hakenartiger Abschnitt 21 bzw. hakenartiger Abschnitt 27 an die Krümmung der Riffelwalze 11 angepaßt. Wie zu erkennen, ist für eine ausreichende Abdichtung gesorgt.The suction box 14 has on the side facing the support beam 17 a side stop 25 which, as shown at 26, cooperates sealingly with an extension 27 of the support beam 17. On the underside hook-like section 21 or hook-like section 27 are adapted to the curvature of the corrugated roller 11. As can be seen, there is sufficient sealing.

Der Saugkasten 13 ist mit Hilfe einer nicht gezeigten Verstellvorrichtung von der Riffelwalze 11 fort bzw. auf diese zu verstellbar. Eine Position im Abstand zur Riffelwalze 11 ist durch die gestrichelte Linie 28 angedeutet. Der Tragbalken 17 ist mit Hilfe einer Zugfeder 29 in Richtung von der Riffelwalze 11 fort beaufschlagt. Wird mithin der Saugkasten 14 von der Riffelwalze fort verstellt, bewegt sich auch der Tragbalken 17 von der Riffelwalze fort. Dies jedoch nur bis zu einem nicht gezeigten Anschlag, der dafür sorgt, daß die Abdichtbleche 18 nicht aus den Saugnuten 16 herausgelangen. Wird der Saugkasten 14 wieder zurückverstellt, nimmt er auf dem letzten Weg den Tragbalken 17 mit in die in der Figur gezeigten Stellung. Es versteht sich, daß auch insoweit ein Anschlag mit dem Tragbalken 17 zusammenwirken kann.The suction box 13 can be moved away from the corrugating roller 11 with the aid of an adjusting device (not shown) or can be adjusted thereon. A position at a distance from the corrugating roller 11 is indicated by the dashed line 28. The support beam 17 is acted upon by a tension spring 29 in the direction away from the corrugating roller 11. Thus, if the suction box 14 is moved away from the corrugated roller, the support beam 17 also moves away from the corrugated roller. However, this only up to a stop, not shown, which ensures that the sealing plates 18 do not get out of the suction grooves 16. If the suction box 14 is moved back again, it takes the supporting beam 17 into the position shown in the figure on the last path. It goes without saying that a stop can also cooperate with the supporting beam 17 in this respect.

Man erkennt, daß durch Ausheben des Saugkastens 14 ein leichter Zugang zur Riffelwalze 11 gescbaffen ist.It can be seen that an easy access to the corrugating roller 11 is provided by lifting the suction box 14.
