Definitions
- the invention relates to a washing device for a printing machine for cleaning the surface of cylindrical bodies (rollers or cylinders), e.g. for cleaning the surface of the blanket of a blanket cylinder.
- a washing device essentially consists of a wipe roller and a wipe roller for receiving a wash cloth which is soaked with washing liquid and is pulled off the wipe roller to the wipe roller.
- a pressure element e.g. a washing roller or a membrane part to which compressed air can be applied.
- the washcloth must always be kept under tension, otherwise it will sag, form loops or can be pulled into the press.
- Such a washing device is known for example from DE 3 005 469 C2.
- the take-up roller dirty cloth roller
- the take-up roller gradually pulls the wash cloth off the fresh cloth roller.
- a washing cloth feeder which is intended to prevent the washing cloth from folding up or sagging.
- the supply of washcloth is controlled by means of a spring element and a braking device.
- a coil spring is arranged as a spring element with one end on a sleeve, which concentrically, frictionally wraps around the freshener roller shaft, and fixed at the other end to a fixed support. The spring is stretched by a defined amount during the transport of the washcloth this prevents the formation of wrinkles or sagging of the washcloth.
- a brake shoe engages the shaft of the fresh cloth roller and controls the cloth feed.
- a cleaning device with a magazine roll which has a spring brake for regulating the tension of the washcloth.
- the washcloth is transported on a take-up roll, which is coupled to a motor.
- a spring brake which brakes an axis in a rotational calculation and releases in the opposite direction.
- the object of the invention is to improve these disadvantages.
- the solution according to the invention has a low breakaway torque, ie the transition from holding friction (start-up / static friction) to sliding friction takes place smoothly and not abruptly. When starting, the sliding speed increases steadily from zero. This means that the washcloth does not form any loops or sag during transport. Tearing through the washcloth, "seizing up" of the cleaning cloth roller or stick-slip movements are avoided.
- the spring band freewheel effects the required washing cloth tension due to its spring-back.
- the shaft of the fresh cloth roller can have a hardened or coated surface in the looping area of the spring band freewheel.
- a liner connected to the shaft. A torque is only transmitted in the direction of pull of the wash cloth in which the spring band freewheel freewheels and locks in the opposite direction (rest position of the shaft of the fresh cloth roller).
- a washing device for rotary printing machines is described below, with only one cylindrical body 10, e.g. a blanket cylinder is shown.
- the washing device is designed as a slide-in system and in the installed state is assigned to the cylindrical body 10 designed as a blanket cylinder.
- the washing device is brought into or out of contact with the blanket cylinder 10 by means of an adjusting device (not further described).
- a washing liquid supply is assigned to the washing device in a machine-fixed manner and is not described in more detail in the present example.
- the washing device essentially consists of two side parts 8, 9 arranged parallel to one another, in which a fresh cloth roller 2, a washing roller 5 and a dirty cloth roller 6 are rotatably mounted.
- the fresh cloth roller 2 serves as a supply roller and has a shaft 1 which receives the respective supply of wash cloth 4.
- the washing roller 5 consists of a shaft which has an elastic coating and serves as a pressing element to press the washing cloth 4 against the cylindrical body 10 and to run the washcloth 4 at the same time.
- the dirty cloth roller 6 serves as a take-up roller for the soiled washing cloth 4 and has a shaft 13 which can be driven in cycles.
- the side parts 8, 9 are connected to one another via a cross member 7.
- the washcloth 4 is guided by the wiping roll 2 in the greatest possible wrap angle over the washing roll 5 in the pulling direction Z of the dirty cloth roll 6.
- a spring band freewheel 3 is arranged on an exposed end of the shaft 1 of the fresh cloth roller 2 between the bearing point in the associated side part, for example position 9 and the supply of washing cloth 4.
- the spring band freewheel 3 consists in the present example of a torsion spring. This wraps non-positively around the shaft 1, including the spring end 11.
- the other end 12 is supported on a fixed frame part, for example the cross member 7.
- the winding direction of the torsion spring is designed such that the inner diameter of the torsion spring increases when the shaft 1 is rotated in the pulling direction Z.
- the spring band freewheel 3 designed as a torsion spring, non-positively wraps around the shaft 1 of the fresh cloth roller and locks, due to frictional engagement, the shaft 1 in the opposite direction to the pulling direction Z.
- the wash cloth 4 is wetted via a washing liquid supply (not shown).
- a drive A is introduced onto the dirty cloth roller 6 via shaft 13 and gearwheel 14.
- the dirty cloth roller 6 is operated intermittently and pulls the wash cloth 4 from the fresh cloth roll 2 over the wash roll 5, which brings the wash cloth 4 into contact with the cylindrical body 10 to be cleaned, in the pulling direction Z and takes up the wash cloth 4 on shaft 13.
- the torsion spring is opened by the transport of the washcloth 4 in the pulling direction 7 caused by the shaft 13.
- the inner diameter of the torsion spring is increased when the shaft 1 is rotated because the end 12 is fixed.
- the tension of the washcloth decreases, so that the frictional torque of the spring band freewheel 3 increases until the shaft stands still (blocked position).
- the spring end of the spring band freewheel 3 can be supported on an adjacent side part 8, 9 or an adjacent shaft, such as the dirty cloth roller 6.
- the spring band freewheel 3 preferably has a circular or rectangular cross section.
- the surface of the shaft 1 can have a wear-resistant coating in the area of the spring band freewheel 3.

Abstract
Description
Die Erfindung betrifft eine Waschvorrichtung für eine Druckmaschine zum Reinigen der Oberfläche zylindrischer Körper (Walzen oder Zylinder), z.B. zur Reinigung der Oberfläche des Gummituches eines Gummituchzylinders. Eine solche Waschvorrichtung besteht im wesentlichen aus einer Frischtuchwalze und einer Schmutztuchwalze zur Aufnahme eines Waschtuches, welches mit Waschflüssigkeit getränkt wird und von der Frischtuchwalze zur Schmutztuchwalze abgezogen wird. Um das Waschtuch an den zylindrischen Körper anzudrücken ist zwischen den beiden Walzen bevorzugt ein Andrückelement, z.B. eine Waschwalze oder ein mit Druckluft beaufschlagbares Membranteil, angeordnet. Das Waschtuch ist dabei immer unter Zugspannung zu halten, da sonst dieses durchhängt, Schlaufen bildet oder in die Druckmaschine gezogen werden kann.The invention relates to a washing device for a printing machine for cleaning the surface of cylindrical bodies (rollers or cylinders), e.g. for cleaning the surface of the blanket of a blanket cylinder. Such a washing device essentially consists of a wipe roller and a wipe roller for receiving a wash cloth which is soaked with washing liquid and is pulled off the wipe roller to the wipe roller. In order to press the washcloth onto the cylindrical body, a pressure element, e.g. a washing roller or a membrane part to which compressed air can be applied. The washcloth must always be kept under tension, otherwise it will sag, form loops or can be pulled into the press.
Eine derartige Wascheinrichtung ist zum Beispiel aus der DE 3 005 469 C2 bekannt. Über einen Kugeltrieb, Antriebswelle und Einwegkupplung zieht die Aufwickelwalze (Schmutztuchwalze) schrittweise das Waschtuch von der Frischtuchwalze ab.Such a washing device is known for example from DE 3 005 469 C2. Via a ball drive, drive shaft and one-way clutch, the take-up roller (dirty cloth roller) gradually pulls the wash cloth off the fresh cloth roller.
Weiterhin ist aus der EP 0 479 403 A2 eine Waschtuchzuführung bekannt, die das Zusammenfalten bzw. Durchsacken des Waschtuches verhindern soll. Mittels Federelement und Bremseinrichtung wird die Waschtuchzufuhr gesteuert. Eine Spiralfeder ist als Federelement mit einem Ende an einer Hülse, welche konzentrisch, reibschlüssig die Frischtuchwalzenwelle umschlingt, angeordnet und mit dem anderen Ende an einem festen Auflager fixiert. Während des Waschtuchtransports wird die Feder um einen definierten Betrag gestreckt und verhindert dadurch die Faltenbildung bzw. das Durchsacken des Waschtuches. Ein Bremsbacken greift an der Welle der Frischtuchwalze an und steuert die Tuchzufuhr.Furthermore, from EP 0 479 403 A2 a washing cloth feeder is known which is intended to prevent the washing cloth from folding up or sagging. The supply of washcloth is controlled by means of a spring element and a braking device. A coil spring is arranged as a spring element with one end on a sleeve, which concentrically, frictionally wraps around the freshener roller shaft, and fixed at the other end to a fixed support. The spring is stretched by a defined amount during the transport of the washcloth this prevents the formation of wrinkles or sagging of the washcloth. A brake shoe engages the shaft of the fresh cloth roller and controls the cloth feed.
Nachteilig bei diesen Lösungen ist, daß ein hoher Aufwand (große Anzahl von Bauteilen) erforderlich ist, um die Zugspannung und den Transport des Waschtuches zu steuern.The disadvantage of these solutions is that a high outlay (large number of components) is required to control the tension and the transport of the washcloth.
Aus der EP 0 435 269 B1 ist eine Reinigungsvorrichtung mit einer Magazinrolle bekannt, die eine Federbremse zur Regelung der Spannung des Waschtuches besitzt. Das Waschtuch wird auf eine Aufwickelrolle transportiert, die mit einem Motor gekoppelt ist.From EP 0 435 269 B1 a cleaning device with a magazine roll is known, which has a spring brake for regulating the tension of the washcloth. The washcloth is transported on a take-up roll, which is coupled to a motor.
Gemäß dem DE-G 8 800 180.6 ist eine Federbremse bekannt, die in eine Drehrechung eine Achse abbremst und in Gegenrichtung sich löst.According to DE-G 8 800 180.6, a spring brake is known which brakes an axis in a rotational calculation and releases in the opposite direction.
Aufgabe der Erfindung ist es, diese Nachteile zu verbessern.The object of the invention is to improve these disadvantages.
Erfindungsgemäß wird das durch den kennzeichnenden Teil des Hauptanspruches gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen. Die erfindungsgemäße Lösung hat ein niedriges Losbrechmoment, d.h. der Übergang von Haltereibung (Anlauf-/Haftreibung) zur Gleitreibung erfolgt gleichmäßig und nicht abrupt. Beim Anlaufen nimmt die Gleitgeschwindigkeit, ausgehend von Null, ansteigend stetig zu. Das bewirkt, daß das Waschtuch keine Schlaufen bildet oder während des Transportes durchsackt. Ein Durchreißen des Waschtuches, ein "Festfressen" der Frischtuchwalze oder Stick-Slip-Bewegungen werden vermieden. Der Federbandfreilauf bewirkt die erforderliche Waschtuchspannung durch seine Rückfederung.According to the invention that is solved by the characterizing part of the main claim. Further training results from the subclaims. The solution according to the invention has a low breakaway torque, ie the transition from holding friction (start-up / static friction) to sliding friction takes place smoothly and not abruptly. When starting, the sliding speed increases steadily from zero. This means that the washcloth does not form any loops or sag during transport. Tearing through the washcloth, "seizing up" of the cleaning cloth roller or stick-slip movements are avoided. The spring band freewheel effects the required washing cloth tension due to its spring-back.
Die erfindungsgemäße Lösung ist betriebssicher und Bedarf keiner großen Anzahl von Bauteilen. Je nach Bedarf kann die Welle der Frischtuchwalze im Umschlingungsbereich des Federbandfreilaufes eine gehärtete oder beschichtete Oberfläche aufweisen. Alternativ dazu ist auch die Verwendung einer mit der Welle verbundenen Laufbüchse möglich. Ein Drehmoment wird nur in Zugrichtung des Waschtuches übertragen in dem der Federbandfreilauf freiläuft und in Gegenrichtung (Ruhelage der Welle der Frischtuchwalze) sperrt.The solution according to the invention is reliable and does not require a large number of components. Depending on requirements, the shaft of the fresh cloth roller can have a hardened or coated surface in the looping area of the spring band freewheel. Alternatively, it is also possible to use a liner connected to the shaft. A torque is only transmitted in the direction of pull of the wash cloth in which the spring band freewheel freewheels and locks in the opposite direction (rest position of the shaft of the fresh cloth roller).
Die erfindungsgemäße Lösung soll an einem Ausführungsbeispiel näher erläutert werden.The solution according to the invention will be explained in more detail using an exemplary embodiment.

Nachstehend wird eine Waschvorrichtung für Rotationsdruckmaschinen beschrieben, wobei von der Druckmaschine lediglich ein zylindrischer Körper 10, z.B. ein Gummituchzylinder, dargestellt ist. Die Waschvorrichtung ist als Einschubsystem ausgebildet und ist im Einbauzustand dem als Gummituchzylinder ausgeführten zylindrischen Körper 10 zugeordnet. Über eine nicht weiter beschriebene Anstellvorrichtung wird die Waschvorrichtung mit dem Gummituchzylinder 10 in oder außer Kontakt gebracht. Eine Waschflüssigkeitszufuhr ist maschinenfest der Waschvorrichtung zugeordnet und wird im vorliegenden Beispiel nicht näher beschrieben.A washing device for rotary printing machines is described below, with only one
Die Waschvorrichtung besteht im wesentlichen aus zwei parallel zueinander angeordneten Seitenteilen 8, 9 in denen eine Frischtuchwalze 2, einer Waschwalze 5 und eine Schmutztuchwalze 6 drehbar gelagert sind. Die Frischtuchwalze 2 dient als Vorratswalze und besitzt eine Welle 1, die den jeweiligen Vorrat von Waschtuch 4 aufnimmt. Die Waschwalze 5 besteht aus einer Welle, die eine elastische Beschichtung aufweist und dient als Andrückelement um das Waschtuch 4 an den zylindrischen Körper 10 anzupressen und gleichzeitig das Waschtuch 4 zu führen. Die Schmutztuchwalze 6 dient als Aufwickelwalze für das verschmutzte Waschtuch 4 und besitzt eine Welle 13, die taktweise antreibbar ist. Die Seitenteile 8, 9 sind über eine Traverse 7 untereinander verbunden. Das Waschtuch 4 ist von der Frischtuchwalze 2 in einem möglichst großen Umschlingungswinkel über die Waschwalze 5 in Zugrichtung Z der Schmutztuchwalze 6 geführt. Auf einem freiliegenden Ende der Welle 1 der Frischtuchwalze 2 ist zwischen der Lagerstelle in dem zugeordneten Seitenteil, z.B. Position 9 und dem Vorrat von Waschtuch 4 ein Federbandfreilauf 3 angeordnet. Der Federbandfreilauf 3 besteht im vorliegenden Beispiel aus einer Schenkeldrehfeder. Diese umschlingt kraftschlüssig die Welle 1, einschließlich dem Federende 11. Das andere Ende 12 stützt sich an einem feststehenden Gestellteil, z.B. der Traverse 7, ab. Der Wicklungssinn der Schenkeldrehfeder ist derart ausgeführt, daß der Innendurchmesser der Schenkeldrehfeder sich beim Drehen der Welle 1 in Zugrichtung Z vergrößert.The washing device essentially consists of two
Ist es erforderlich den zylindrischen Körper 10, z.B. den Gummituchzylinder zu reinigen, so wird dieser in Gegendrehrichtung G angetrieben. Der als Schenkeldrehfeder ausgeführte Federbandfreilauf 3 umschlingt kraftschlüssig die Welle 1 der Frischtuchwalze und sperrt, durch Reibschluß bedingt die Welle 1 in Gegenrichtung zur Zugrichtung Z. Das Waschtuch 4 wird über eine Waschflüssigkeitszufuhr (nicht gezeigt) benetzt. Auf die Schmutztuchwalze 6 wird über Welle 13 und Zahnrad 14 ein Antrieb A eingeleitet. Die Schmutztuchwalze 6 wird taktweise betrieben und zieht von der Frischtuchwalze 2 das Waschtuch 4 über die Waschwalze 5, welche das Waschtuch 4 mit dem zu reinigenden zylindrischen Körper 10 in Kontakt bringt, in Zugrichtung Z ab und nimmt das Waschtuch 4 auf Welle 13 auf. Die Schenkeldrehfeder wird dabei durch den von Welle 13 bewirkten Transport des Waschtuches 4 in Zugrichtung 7 geöffnet. Der Innendurchmesser der Schenkeldrehfeder wird beim Drehen der Welle 1 vergrößert, da das Ende 12 fest ist. Ist der Transport des Waschtuches 4 beendet, läßt die Zugspannung des Waschtuches nach, so daß das Reibmoment des Federbandfreilaufes 3 sich erhöht bis die Welle stillsteht (Sperrlage).If it is necessary to clean the
Die erfindungsgemäße Lösung beschränkt sich nicht auf dieses Ausführungsbeispiel. So kann z.B. das Federende des Federbandfreilaufes 3 auf einem benachbarten Seitenteil 8, 9 oder einer benachbarten Welle, wie z.B. der Schmutztuchwalze 6 abgestützt sein. Der Federbandfreilauf 3 weist vorzugsweise einen Kreis- oder Rechteckquerschnitt auf. Die Oberfläche der Welle 1 kann im Bereich des Federbandfreilaufes 3 eine verschleißfeste Beschichtung aufweisen.The solution according to the invention is not limited to this exemplary embodiment.
