Description

Die Erfindung bezieht sich auf einen Kalander für Bahnen aus Feuchtigkeit enthaltendem Material, wie Papier, mit einem zwei Seitenteile aufweisenden Ständer und einem Walzenstapel, wobei sich zwischen den Seitenteilen ein zumindest durch den Walzenstapel und die Bahn begrenzter Raum befindet.The invention relates to a calender for webs from moisture-containing material, such as paper, with a stand with two side parts and one Roll stack, being between the side parts a limited at least by the roll stack and the web Room is located.

Der Raum zwischen den Seitenteilen des Ständers ist üblicherweise an einer vertikal oder schrägverlaufenden Stirnseite durch den Walzenstapel und unten durch den Boden der Werkhalle begrenzt. Kommen weitere Begrenzungen durch die Bahn hinzu, beispielsweise an der Oberseite und an der dem Walzenstapel gegenüberliegenden Seite, so ergibt sich ein weitgehend geschlossener Raum, der mit der umgebenden Atmosphäre nur noch in geringem Maß im Austausch steht. Dies gilt insbesondere für einen In-Line-Kalander, der nahe den Trockenzylindern der Papiermaschine angeordnet ist, aber auch für einen Off-Line-Kalander mit dicht benachbarter Abwikkelvorrichtung.The space between the side parts of the stand is common on a vertical or inclined one Front through the roller stack and below through the Limited floor of the workshop. Coming further limits through the web, for example at the top and on the opposite side of the roll stack Side, so there is a largely closed Space with the surrounding atmosphere in only a small amount Measure is in exchange. This is especially true for an in-line calender that is close to the drying cylinders the paper machine is arranged, but also for an off-line calender with a closely adjacent unwinder.

Da der begrenzte Raum nur unvollkommen mit der Umgebungsatmosphäre in Verbindung steht, steigt in ihm die Luftfeuchtigkeit aufgrund der Feuchte der Papierbahn oder eines Dampffeuchtereinsatzes an. Die Luft im begrenzten Raum ist gesättigt, so daß sich Nebeltropfen bilden. Zusätzlich kondensiert die Feuchtigkeit an den kühleren Bauteilen, wie beispielsweise dem Ständer, woraus sich eine Korrosionsgefahr ergibt. Außerdem besteht ständig die Gefahr, daß Tropfen von Kalanderbauteilen auf die Bahn fallen. Nicht zuletzt ist die hohe Feuchtigkeit auch für das Bedienungspersonal unangenehm.Because the limited space is only imperfect with the surrounding atmosphere communicates, the rises in him Air humidity due to the moisture of the paper web or a steam humidifier insert. The air in the limited Space is saturated, so that fog drops form. In addition, the moisture condenses on the cooler components, such as the stand, resulting in a risk of corrosion. There is also constantly the risk of drops from calender components fall on the track. Last but not least is the high one Moisture also uncomfortable for the operating personnel.

Der Erfindung liegt die Aufgabe zugrunde, einen Kalander der eingangs beschriebenen Art anzugeben, mit dem die Feuchtigkeitsprobleme unter Beibehaltung der Begrenzungen des Raumes gelöst sind.The invention has for its object a calender of the type described at the beginning with which the moisture problems while maintaining the limits of the room are solved.

Diese Aufgabe wird erfindungsgemäß gelöst durch ein Gebläse, das trockene Luft in den begrenzten Raum bläst.According to the invention, this object is achieved by a blower, that blows dry air into the confined space.

Dies hat einen doppelten Effekt. Zum einen entsteht ein geringer Überdruck im begrenzten Raum, durch den feuchte Luft über die immer noch verbleibenden Öffnungen in die Umgebung herausgedrückt wird. Zum anderen sorgt der Trockenzustand der Gebläseluft dafür, daß die feuchte Atmosphäre im begrenzten Raum den Sättigungszustand verläßt und damit die Gefahr der Tröpfchenbildung vermieden wird. Auch ist die Atmosphäre für das Bedienungspersonal wesentlich angenehmer. This has a double effect. On the one hand, one emerges low overpressure in the limited space due to the damp Air through the remaining openings in the environment is pushed out. On the other hand, the The fan air is dry to ensure that it is moist Atmosphere in the limited space the saturation state leaves, thus avoiding the risk of droplet formation becomes. Also, the atmosphere is great for the operators much more pleasant.

Günstig ist es, daß eine Heizvorrichtung für die Gebläseluft vorgesehen ist. Die Gebläseluft kann demnach mit höherer Temperatur zugeführt werden und daher den Trocknungseffekt der Luft im begrenzten Raum noch verbessern.It is favorable that a heater for the fan air is provided. The blower air can therefore with higher temperature and therefore the Improve the drying effect of the air in a limited space.

Bei einer bevorzugten Ausführungsform ist dafür gesorgt, daß innerhalb des begrenzten Raumes mindestens ein Feuchtigkeitssensor und/oder mindestens ein Temperatursensor angeordnet sind, daß ein Rechner vorgesehen ist, der unter Berücksichtigung der Sensor-Meßwerte die zur Vermeidung des Sättigungszustandes der Luft im begrenzten Raum erforderliche Gebläseluftdaten berechnet, und daß vom Rechner gesteuerte Mittel zur Einstellung der Gebläseluftdaten vorgesehen sind. Durch die Überwachung der Atmosphäre im begrenzten Raum und die von den Sensor-Meßwerten abhängigen Gebläseluftdaten ist gewährleistet, daß keine Sättigung der feuchten Luft im begrenzten Raum eintritt.In a preferred embodiment, it is ensured that that within the limited space at least a humidity sensor and / or at least one temperature sensor are arranged that a computer is provided is the, taking into account the sensor measured values to avoid the saturation of the air in the limited Space required fan air data calculated, and that means controlled by the computer for adjustment the fan air data are provided. By monitoring the atmosphere in the limited space and that of Fan air data dependent on sensor measured values is guaranteed that there is no saturation of the moist air in the limited space occurs.

Zu diesem Zweck kann mit Vorteil dem Gebläse eine Gebläseluftmengen-Einstellvorrichtung und/oder der Heizvorrichtung eine Gebläselufttemperatur-Einstellvorrichtung zugeordnet sein.For this purpose, a blower air quantity setting device can advantageously be provided to the blower and / or the heater a blower air temperature adjuster be assigned.

Empfehlenswert ist es, daß der Rechner ein Programm aufweist, das die Luft im begrenzten Raum nahe dem Sättigungszustand hält. Auf diese Weise wird sichergestellt, daß keine Übertrocknung der Bahn eintritt, die ja den Raum begrenzt und im Bereich des Walzenstapels durch den Raum transportiert wird.It is recommended that the computer has a program that the air in the limited space near the saturation state holds. This ensures that no overdrying of the web occurs, the yes the space is limited and in the area of the roll stack is transported through the room.

Die Erfindung wird nachstehend anhand eines in der Zeichnung dargestellten bevorzugten Ausführungsbeispiels näher beschrieben. Hierin zeigen:

The invention is described below with reference to a preferred embodiment shown in the drawing. Show here:
Fig. 1
a schematic representation of a calender according to the invention and
Fig. 2
an associated block diagram.

Der veranschaulichte Kalander 1 besitzt einen auf dem Boden 2 stehenden Ständer 3 mit zwei Seitenteilen 4, von denen lediglich das eine Seitenteil zu sehen ist. An der einen Stirnseite der Seitenteile 4 ist ein Walzenstapel 5 angeordnet, dem eine Papierbahn 6 von einer Trockenwalzen-Anordnung 7 einer Papiermaschine über einen vertikalen Abschnitt 8 auf der dem Walzenstapel 5 gegenüberliegenden Stirnseite der Seitenteile 4 und einen oberen Abschnitt 9 zugeführt wird. Die Bahn 6 tritt aus dem Walzenstapel aus und wird auf einer Wickelvorrichtung 10 aufgewickelt.The illustrated calender 1 has one on the Floor 2 standing stand 3 with two side parts 4, of which only the one side part can be seen. At one end of the side parts 4 is a roll stack 5 arranged, a paper web 6 from a Drying roller arrangement 7 of a paper machine over a vertical section 8 on the roll stack 5 opposite end of the side parts 4 and one upper section 9 is supplied. Lane 6 occurs out of the roll stack and is on a winder 10 wound up.

Zwischen den Seitenteilen 4 ergibt sich ein Raum 11, der durch den Boden 2, den Walzenstapel 5 und die Bahnabschnitte 8 und 9 begrenzt ist. Dieser Raum steht nur über wenige Öffnungen mit der umgebenden Atmosphäre 12 in Verbindung. In ihm herrscht normalerweise ein sehr hoher Feuchtigkeitszustand.There is a space 11 between the side parts 4, through the bottom 2, the roll stack 5 and the web sections 8 and 9 is limited. This room just stands through a few openings with the surrounding atmosphere 12 in connection. There is usually a lot in it high level of moisture.

Es ist ein Gebläse 13 vorgesehen, das trockene Luft in den begrenzten Raum 11 bläst. Die Gebläseluftdaten, wie Menge, Temperatur, Trocknungsgrad u.dgl. werden von einem Rechner 14 vorgegeben, der unter dem Einfluß von Meßwerten eines Feuchtigkeits-Sensors 15 und eines Temperatur-Sensors 16 und gegebenenfalls noch weiterer Sensoren steht, die beispielsweise die relative Feuchte und die Temperatur der Atmosphäre im begrenzten Raum 11 feststellen. A blower 13 is provided which intakes dry air blows the limited space 11. The fan air data, such as Amount, temperature, degree of drying, etc. be from one Computer 14 given the under the influence of Measured values of a moisture sensor 15 and a temperature sensor 16 and possibly even more Sensors, for example, the relative humidity and the temperature of the atmosphere in the confined space 11 determine.

Im einzelnen kann dies geschehen, wie es das Blockschaltbild der Fig. 2 zeigt. Der Rechner 14 ist mit je zwei Feuchtigkeits-Sensoren 15 und 15' sowie mit zwei Temperatur-Sensoren 16, 16' verbunden, die jeweils an unterschiedlichen Stellen des begrenzten Raums 11 angeordnet sind, beispielsweise an den Seitenteilen 4. Über Eingänge 17 und 18 werden dem Rechner 14 Sollwerte der Feuchtigkeit und der Temperatur im begrenzten Raum 11 vorgegeben. Das Gebläse 13 besitzt eine Gebläseluftmengen-Einstellvorrichtung 19, die die Form eines einstellbaren Motors hat, der vom Rechner 14 gesteuert wird. Dem Gebläse 13 ist eine Heizvorrichtung 20 vorgeschaltet, die eine Gebläseluft mit einer vom Rechner 14 vorgesehenen Temperatur abgibt, was mittels einer Gebläselufttemperatur-Einstellvorrichtung 21 in der Form eines einstellbaren Heizstromreglers geschieht.In detail, this can be done as is the block diagram 2 shows. The computer 14 is with each two humidity sensors 15 and 15 'and two Temperature sensors 16, 16 'connected to each different locations of the limited space 11 arranged are, for example on the side parts 4. About Inputs 17 and 18 are the computer 14 setpoints of the Humidity and temperature in a limited space 11 specified. The blower 13 has a blower air amount adjusting device 19 which is the shape of an adjustable Motors has controlled by the computer 14 becomes. A heater 20 is connected upstream of the fan 13, the one fan air with a from the computer 14 provided temperature, what by means of a blower air temperature adjusting device 21 in the form an adjustable heating current controller happens.

Die Gesamtanordnung kann derart betrieben werden, daß die Gebläseluft in einer solchen Menge, mit einer solchen Temperatur und mit einem solchen Trocknungsgrad zugeführt wird, daß die Atmosphäre im begrenzten Raum 11 außerhalb des Sättigungszustandes liegt, also Tröpfchenbildung und Nässe ganz oder weitgehend vermieden wird. Insbesondere kann der Rechner 14 ein Programm aufweisen, das die Atmosphäre im begrenzten Raum 11 zwar außerhalb des Sättigungszustandes, aber noch nahe diesem Zustand hält, damit die hindurchlaufende Bahn 6 nicht einer unerwünschten Trocknung ausgesetzt wird.The overall arrangement can be operated such that the fan air in such an amount, with such an amount Temperature and with such a degree of dryness that the atmosphere is supplied in limited space 11 is outside the saturation state, i.e. droplet formation and completely or largely avoided wetness becomes. In particular, the computer 14 can run a program that the atmosphere in the limited space 11th outside the saturation state, but still close holds this state, so that the web 6 passing therethrough is not exposed to undesirable drying.

Angestrebt wird eine relative Feuchte, also das Verhältnis der Masse des in der Luft enthaltenen Wasserdampfes zur Masse des Wasserdampfes bei Sättigung, von 75 bis 95 %, vorzugsweise 85 bis 90 %. The aim is a relative humidity, i.e. the ratio the mass of water vapor in the air to the mass of water vapor when saturated, from 75 to 95%, preferably 85 to 90%.

Statt eines Gebläses 13 können auch mehrere Gebläse vorgesehen sein, die trockene Luft an verschiedenen Stellen des begrenzten Raumes 11 in diesen einleiten.Instead of one blower 13, several blowers can also be used be provided, the dry air at different Introduce the limited space 11 into this.

Als trockene Luft genügt in manchen Fällen bereits die Luft der umgebenden Atmosphäre. Empfehlenswert ist es jedoch, die Luft vorzutrocknen, beispielsweise durch Abkühlung unter den Taupunkt und anschließendes Wiedererwärmen.In some cases, dry air is sufficient Air of the surrounding atmosphere. It is recommended however, to pre-dry the air, for example by Cooling down below the dew point and then reheating.

Als "trocken" im Sinne der Erfindung wird Luft angesehen, wenn sie einen Feuchtigkeitsgehalt hat, der geringer, vorzugsweise erheblich geringer ist als es der Feuchtigkeitsgehalt der Atmosphäre im begrenzten Raum 11. Wichtig ist es, daß die Gebläseluft sich mit der Luft im begrenzten Raum 11 mischt und diese Mischung eine Feuchtigkeit und eine Temperatur hat, die dicht oberhalb der Sättigungstemperatur liegt. Bevorzugt wird eine Überhitzung von 5 bis 10°C.Air is considered "dry" in the sense of the invention, if it has a moisture content that is less, is preferably considerably less than that Moisture content of the atmosphere in a limited space 11. It is important that the fan air matches the Air in the limited space 11 mixes and this mixture has a humidity and a temperature that is tight is above the saturation temperature. Is preferred an overheating of 5 to 10 ° C.

Das Gebläse ist auch anwendbar bei Kalandern, bei denen die Seitenteile einen Walzenstapel tragen, dessen Stapelebene in einem Winkel zur Horizontalen verläuft.The blower can also be used on calenders where the side parts carry a stack of rollers, the stacking level runs at an angle to the horizontal.
