Definitions
- the invention relates to a device for preventing damage to production facilities with rotating cylinders, preferably rubber cylinders of web-fed rotary printing presses, according to the preamble of claim 1.
- Such a generic device is such. B. become known from DE-PS 5 58 071.
- a disadvantage of this device is that the conveying speed of the torn paper web is also dependent on the inertial masses of the two rollers involved. Particularly when used after an offset printing unit, it cannot be avoided that the web winds up on the blanket cylinder and printing unit damage can occur.
- the invention has for its object to provide a device for preventing damage due to web breaks in production units, with which it is possible in a web break between two rotating clamping locations for the web, preferably two pairs of rubber cylinders of two printing units of an offset web-fed rotary printing press, the web transport the subsequent, rotating Clamping location, e.g. B. to design the first pair of rubber cylinders such that winding of the web onto the re-feeding clamping location is avoided.
- the cylinders 4, 6 are preferably rubber cylinders of the web-fed rotary printing press.
- Between the two clamping locations 2, 3 there is a web guide roller 9, which has the function of a pull-out roller and z. B. is mounted on a shaft 11. Through this web guide roller 9 and elastic rollers 12 set thereon with a defined force, further clamping locations 13 of the web 1 are formed. At least two, in the example shown three, of these rollers 12 are arranged on the web guide roller 9. Alternatively, a roller can be used instead of the rollers 12.
- rollers 12 The function of the rollers 12 is described in more detail below using the example of a roller 12.
- the roller 12 is rotatably attached to a lever 14.
- This lever 14 is pivotable about a spindle 16 which runs parallel to the web guide roller 9 and is arranged fixed to the frame axially displaceable.
- the lever 14 can be pivoted away from the web guide roller 9, so that a gap is formed between the roller 12 and web guide roller 9, for. B. to facilitate the retraction of the web 1.
- the web guide roller 9 can execute a rotating movement on the shaft 11.
- This shaft 11 is in turn rotatably supported in the frames 18, 19.
- the shaft 11 is driven by a drive which, in the exemplary embodiment, is formed from a torque-switched clutch 21, an intermediate wheel 22, a cylinder drive wheel 23 and a drive wheel 25.
- the web guide roller 9 is caused by frictional engagement of the clutch 24 the shaft 11 at a lower speed than that of the web guide roller 9 temporarily driven in the web direction.
- the speed difference between the shaft 11 and the web guide roller 9 can be in the range from 0.2% to 1.5% and is preset for a selected value. This ensures that the re-conveyed end of the torn web 1 is transported through the web guide roller 9 and pair of cylinders 7, 8 in the direction of the clamping location 13 until the cylinders 7, 8 have come to a standstill.
- the torque-switched coupling 21 releases the connection between the shaft 11 and the power input z when a defined torque is exceeded.

Description
Die Erfindung betrifft eine Vorrichtung zum Verhindern von Schäden an Produktionseinrichtungen mit rotierenden Zylindern, vorzugsweise Gummizylindern von Rollenrotationsdruckmaschinen, gemäß dem Oberbegriff des Anspruches 1.The invention relates to a device for preventing damage to production facilities with rotating cylinders, preferably rubber cylinders of web-fed rotary printing presses, according to the preamble of claim 1.
Eine derartige gattungsgemäße Vorrichtung ist z. B. durch die DE-PS 5 58 071 bekanntgeworden. Nachteilig bei dieser Einrichtung ist, daß die Fördergeschwindigkeit der abgerissenen Papierbahn mit abhängig ist von den Schwungmassen der beiden beteiligten Walzen. Insbesondere bei einem Einsatz nach einem Offset-Druckwerk kann nicht vermieden werden, daß sich die Bahn auf dem Gummizylinder aufwickelt und es so zu Druckwerkschäden kommen kann.Such a generic device is such. B. become known from DE-PS 5 58 071. A disadvantage of this device is that the conveying speed of the torn paper web is also dependent on the inertial masses of the two rollers involved. Particularly when used after an offset printing unit, it cannot be avoided that the web winds up on the blanket cylinder and printing unit damage can occur.
Der Erfindung liegt die Aufgabe zugrunde, in Produktionseinheiten eine Vorrichtung zum Verhindern von Schäden durch Warenbahnrisse zu schaffen, mit der es möglich ist, bei einem Warenbahnriß zwischen zwei rotierenden Einspannorten für die Warenbahn, vorzugsweise zwei Gummizylinderpaaren zweier Druckwerke einer Offset-Rollenrotationsdruckmaschine, den Bahntransport aus den nachfördernden, rotierenden Einspannort, z. B. des ersten Gummizylinderpaares derart zu gestalten, daß ein Aufwickeln der Warenbahn auf den nachfördernden Einspannort vermieden wird.The invention has for its object to provide a device for preventing damage due to web breaks in production units, with which it is possible in a web break between two rotating clamping locations for the web, preferably two pairs of rubber cylinders of two printing units of an offset web-fed rotary printing press, the web transport the subsequent, rotating Clamping location, e.g. B. to design the first pair of rubber cylinders such that winding of the web onto the re-feeding clamping location is avoided.
Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß ein aus den fördernden Zylindern austretendes Ende einer gerissenen Warenbahn weiter kontrolliert gefördert wird, bis die fördernden Zylinder zum Stillstand gekommen sind. Durch die Wahl einer Umdrehungsdifferenz zwischen Papierleitwalze und einer in ihr angeordneten richtungsgeschalteten Kupplung, z. B. mit Treiberstern versehener Klemmrollenfreilauf, ist es möglich, ziemlich genau zu bestimmen, um wieviele Zentimeter das abgetrennte Ende von den fördernden Zylindern max. zurückgezogen wird, bis die Vorrichtung wirkt.The advantages which can be achieved with the invention consist in particular in that an end of a torn material web emerging from the conveying cylinders is conveyed in a controlled manner until the conveying cylinders have come to a standstill. By choosing a rotation difference between the paper guide roller and a directional clutch arranged in it, e.g. B. provided with starter pinch roller freewheel, it is possible to determine fairly precisely by how many centimeters the separated end of the conveying cylinders max. withdrawn until the device operates.

Eine Warenbahn 1, vorzugsweise eine Papierbahn in einer Offset-Rollenrotationsdruckmaschine, wird zwischen zwei Einspannorten 2, 3, die beispielsweise von jeweils paarweise angeordneten, rotierenden Zylindern 4, 6 bzw. 7, 8 gebildet werden, mit definierter Bahnspannung transportiert Die Zylinder 4, 6 sind vorzugsweise Gummizylinder der Rollenrotationsdruckmaschine. Zwischen den beiden Einspannorten 2, 3 befindet sich eine Bahnleitwalze 9, welche die Funktion einer Auszugswalze hat und z. B. auf einer Welle 11 gelagert ist. Durch diese Bahnleitwalze 9 und darauf mit definierter Kraft angestellten, elastischen Rollen 12 werden weitere Einspannorte 13 der Warenbahn 1 gebildet. Von diesen Rollen 12 werden mindestens zwei, im dargestellten Beispiel drei, auf der Bahnleitwalze 9 angeordnet. Alternativ kann statt den Rollen 12 eine Walze verwendet werden.A web 1, preferably a paper web in an offset web-fed rotary printing press, is transported with a defined web tension between two
Nachfolgend wird die Funktion der Rollen 12 am Beispiel einer Rolle 12 näher beschrieben. Die Rolle 12 ist drehbar an einem Hebel 14 befestigt. Dieser Hebel 14 ist um eine Spindel 16, die parallel zur Bahnleitwalze 9 verläuft und gestellfest angeordnet ist, schwenk- und axial verschiebbar.The function of the
Durch Beaufschlagung eines Pneumatikzylinders 17, der auf der Spindel 16 und dem Hebel 14 gelagert ist, wird eine so definierte Kraft in Richtung des Mittelpunktes der Bahnleitwalze 9 erzeugt, daß die Warenbahn 1 am Einspannort 13 sicher durch Friktion transportiert werden kann. Diese Kraft ist auch bei Abstandsveränderungen der Mittelpunkte der Rolle 12 und Bahnleitwalze 9 annähernd konstant.By acting on a
Mittels des Pneumatikzylinders 17 kann der Hebel 14 von der Bahnleitwalze 9 weggeschwenkt werden, so daß zwischen Rolle 12 und Bahnleitwalze 9 ein Spalt entsteht, z. B. um das Einziehen der Warenbahn 1 zu erleichtern.By means of the
Die Bahnleitwalze 9 kann, wie aus Fig. 2 ersichtlich, eine rotierende Bewegung auf der Welle 11 ausführen. Diese Welle 11 ist wiederum in den Gestellen 18, 19 drehbar gelagert.As can be seen in FIG. 2, the
Die Welle 11 wird durch einen Antrieb angetrieben, der im Ausführungsbeispiel aus einer drehmomentgeschalteten Kupplung 21, einem Zwischenrad 22, einem Zylinderantriebsrad 23 und einem Antriebsrad 25 gebildet wird.The
Die Bahnleitwalze 9 wird während der Produktion (= normaler Betriebszustand) mittels Friktion von der Warenbahn 1 mit Bahngeschwindigkeit angetrieben. Durch die richtungsgeschaltete Kupplung 24 besteht während des normalen Betriebszustandes keine Kraftübertragung von Welle 11 auf Bahnleitwalze 9. Diese Kupplung 24 ermöglicht solange ein von der Welle 11 unabhängiges Drehen der Bahnleitwalze 9 bis die Drehzahl der Bahnleitwalze 9 gleich oder kleiner der der Welle 11 ist. Um die unabhängige, freie Rotation der Bahnleitwalze 9 während der Produktion zu gewährleisten, wird die Welle 11 mit einer niedrigeren Drehzahl angetrieben als die Drehzahl der Bahnleitwalze 9.The
Verringert sich die Drehzahl der Bahnleitwalze 9 durch einen Riß der Warenbahn 1 zwischen dem födernden Einspannort 2 und dem ziehenden Einspannort 3, jedoch nach dem Einspannort 13, in Form der "Auszugseinrichtung" 9, 12, wird durch Reibschluß der Kupplung 24 die Bahnleitwalze 9 von der Welle 11 mit geringerer Drehzahl als die der Bahnleitwalze 9 zeitweise in Warenbahnrichtung angetrieben. Die Drehzahldifferenz der Welle 11 zur Bahnleitwalze 9 kann im Bereich von 0,2% bis 1,5% liegen und wird für einen ausgewählten Wert fest voreingestellt. Hierdurch wird sichergestellt, daß das nachgeförderte Ende der gerissenen Warenbahn 1 durch Bahnleitwalze 9 und Zylinderpaar 7, 8 in Richtung Einspannort 13 transportiert wird, bis der Stillstand der Zylinder 7, 8 erreicht ist.If the speed of the
Wickelt sich die Warenbahn 1 während Welle 11 und Bahnleitwalze 9 über die richtungsgeschaltete Kupplung 24 miteinander verbunden sind, um die Bahnleitwalze 9, vergrößert sich damit der wirksame Durchmesser der Bahnleitwalze 9 und damit auch die Transportgeschwindigkeit. Um ein weiteres Reißen der Warenbahn 1 zwischen den Einspannorten 2 und 13 zu vermeiden, löst die drehmomentgeschaltete Kupplung 21 bei Überschreiten eines definierten Drehmomentes die Verbindung zwischen Welle 11 und Krafteintrieb z. B. in Form des Zwischenrades 22. Dieses Drehmoment muß kleiner sein als das max. zulässige Drehmoment der Bahnleitwalze 9, was sich durch die Reißfestigkeit der Warenbahn ergibt. Die Kupplung 21 ist als kraftschlüssige Schaltkupplung z. B. Scheibenreibkupplung ausgeführt.If the web of material 1 is wound around the

Bewegt sich das treibende Teil 26, das in Form eines Treibersternes ausgebildet ist, mit kleinerer Drehzahl als der Abtriebsring 27 und damit als die Bahnleitwalze 9, werden die Klemmrollen 28 in Richtung Federn 29 gedrückt. Wird die Drehzahl des treibenden Teiles 26 größer als die des Abtriebsringes 27, wird über Keilflächen 31 und den Abtriebsring 27 in Verbindung mit den Klemmrollen 28 ein Reibschluß zwischen Welle 11 und Bahnleitwalze 9 erzeugt. Dies ist dann der Fall, wenn die Bahngeschwindigkeit an dem Einspannort 13 geringer als am Einspannort 2 ist.If the driving
In weiteren nicht dargestellten Ausführungsformen der Erfindung kann beispielsweise die Bahnleitwalze 9 an den Gestellen 18, 19 gelagert sein und die Kupplung 24 außerhalb des Gestelles 19 an einem mit der Bahnleitwalze 9 starr verbundenen Wellenende befestigt sein.In further embodiments of the invention, not shown, the
Auch könnte der dargestellte Antrieb 22, 23, 25 durch einen drehzahlgeregelten Antrieb (elektrisch, pneumatisch, hydraulisch) erfolgen, der seinen Sollwert z. B. von einem mit einem der Zylinder 7, 8 gekoppelten Drehzahlgeber z. B. Winkelcodierer erhält.The
