Description

Die Erfindung betrifft eine Vorrichtung zum Verhindern von Druckwerksschäden bei Druckträgerbahnrissen in Rotationsdruckmaschinen mit einem, hinter einem Druckwerk angeordneten, im störungsfreien Betrieb mit etwa Maschinengeschwindigkeit antreibbarem Klemmwalzenpaar, zwischen dem die Druckträgerbahn berührungslos durchführbar ist und bei dem eine Walze in der Weise verschieb- oder verschwenkbar ist, daß beim Auftreten eines Druckträgerbahnrisses die Druckträgerbahn durch das Klemmwalzenpaar erfaßbar ist.The invention relates to a device for preventing printing unit damage in the case of printing carrier web tears in rotary printing presses, with a pair of clamping rollers arranged behind a printing unit, which can be driven in trouble-free operation at approximately machine speed, between which the printing carrier web can be carried out without contact and in which a roller can be displaced or pivoted in this way that when a print carrier web tear occurs, the print carrier web can be detected by the pair of pinch rollers.

Eine Vorrichtung der vorangehenden spezifizierten Art ist bereits aus der DE-Patentschrift 2156 505 bekannt. Bei dieser Vorrichtung ist das Klemmwalzenpaar sowohl während dem störungsfreien Betrieb, als auch während des Fangvorganges über Zahnräderzüge mit etwa Papierbahngeschwindigkeit antreibbar. Bei dieser bekannten Vorrichtung ist es nachteilig, daß die Ansprechgeschwindigkeit bei einem festgestellten Bahnriß verhältnismäßig hoch ist, da mit der Verschwenkbewegung, mit der eine Walze gegen eine feststehende Walze angestellt wird, auch die Antriebszahnräder für die verschwenkbare Walze in Eingriff.bleiben und somit ebenfalls mit verschwenkt werden müssen.A device of the above specified type is already known from DE patent 2156 505. In this device, the pair of pinch rollers can be driven with gear trains at approximately paper web speed both during trouble-free operation and during the catching process. In this known device, it is disadvantageous that the response speed when a web break is detected is relatively high, since with the pivoting movement with which a roller is brought up against a stationary roller, the drive gearwheels for the pivotable roller also remain in engagement and thus also with have to be pivoted.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art in der Weise zu verbessern, daß die Ansprechgeschwindigkeit größer, d. h., die Ansprechzeit geringer als bei der bekannten Vorrichtung wird.The object of the invention is to improve a device of the type mentioned in such a way that the response speed is greater, i. that is, the response time becomes shorter than in the known device.

Diese Aufgabe wird durch die Anwendung der Merkmale des Kennzeichens des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen und aus der Beschreibung in Verbindung mit den Zeichnungen. Im folgenden wird die Erfindung anhand eines Ausführungsbeispieles im einzelnen beschrieben, wobei Bezug auf die beiliegenden Zeichnungen genommen wird. In diesen zeigen etwas schematisiert :

  • Figur 1 eine Papierfangvorrichtung in Vorderansicht und
  • Figur 2 die Vorrichtung gemäß Fig. 1 in Seitenansicht.
This object is achieved by applying the features of the characterizing part of claim 1. Advantageous further developments result from the subclaims and from the description in conjunction with the drawings. In the following the invention is described in detail using an exemplary embodiment, reference being made to the accompanying drawings. These show something schematically:
  • Figure 1 is a paper catcher in front view
  • Figure 2 shows the device of FIG. 1 in side view.

Die in Fig. 1 dargestellten Seitenwände 1, 2 sind hinter dem letzten Druckwerk angeordnet, da vorzugsweise dem letzten von mehreren hintereinander angeordneten Druckwerken die in Fig. 1 und 2 gezeigte Papierfangvorrichtung nachgeordnet sein sollte. Diese umfaßt eine stationär gelagerte Walze 3, die mit ihren Achszapfen 4, 5 in Lagern 6, 7 zwischen den Seitenwänden 1, 2 angeordnet ist. Die Walze 3 wird über den verlängerten Achszapfen 4 über zwei Kegelräder 8, 9 von einer, in üblicher Weise seitlich an den Druckmaschinen horizontal verlaufenden Hauptantriebswellen 10 angetrieben, und zwar vorzugsweise so, daß die Umfangsgeschwindigkeit der Walze 3 mindestens gleich groß wie die Papierbahngeschwindigkeit ist oder zwecks Kompensation von Ansprechverzögerungen geringfügig darüberliegt.The side walls 1, 2 shown in FIG. 1 are arranged behind the last printing unit, since the paper catching device shown in FIGS. 1 and 2 should preferably be arranged after the last of a plurality of printing units arranged one behind the other. This comprises a stationary roller 3, which is arranged with its axle journals 4, 5 in bearings 6, 7 between the side walls 1, 2. The roller 3 is driven via the elongated journal 4 via two bevel gears 8, 9 by a main drive shaft 10, which runs horizontally laterally on the printing presses in the usual way, preferably in such a way that the peripheral speed of the roller 3 is at least the same as the paper web speed or is slightly above this in order to compensate for response delays.

Parallel zu der stationär gelagerten Walze 3 ist zwischen den Seitenwänden 1, 2 eine drehbare Traverse 11 angeordnet, die bspw. einen kreisförmigen Querschnitt aufweisen kann. Mit der Traverse 11 sind Hebel 12, 13 verschwenkbar, die auf dieser verstiftet sind, und die zwischen ihren oberen Enden eine Achse 14 halten, auf der die zweite Walze 15 des Klemmwalzenpaares 3,15 über Lager 16,17 angeordnet ist.Parallel to the stationary roller 3, a rotatable cross member 11 is arranged between the side walls 1, 2, which can for example have a circular cross section. With the traverse 11 levers 12, 13 are pivotable, which are pinned thereon, and which hold an axis 14 between their upper ends, on which the second roller 15 of the pinch roller pair 3.15 is arranged via bearings 16.17.

Im störungsfreien Betrieb verläuft die bei A angedeutete Papierbahn berührungslos durch das Klemmwalzenpaar 3, 15.In trouble-free operation, the paper web indicated at A runs through the pair of pinch rollers 3, 15 without contact.

Die um die Traverse 11 verschwenkbare Walze 15 nimmt dabei die in den Figuren 1, 2 gezeigte Stellung ein, bei der sie durch ein Reibrad 18 ebenfalls mit Maschinengeschwindigkeit oder vorzugsweise mit einer darüberliegenden Geschwindigkeit angetrieben wird. Das Reibrad 18 sitzt auf einer Welle 19, die in nicht näher bezeichneten Lagern in der linken Seitenwand 1 angeordnet ist. Auf dem linken Ende der Welle 19 ist eine Riemenscheibe 20 aufgezogen, die von einem Flachriemen 21 teilweise umschlungen wird, der an seinem oberen Ende um eine weitere Riemenscheibe 22 geführt ist, die auf dem verlängerten Zapfen 4 der stationär gelagerten Walze 3 sitzt. Somit kann die verschwenkbare Walze 15 unmittelbar von der stationär gelagerten Walze 3 her angetrieben werden.The roller 15 which can be pivoted about the crossmember 11 assumes the position shown in FIGS. 1, 2, in which it is driven by a friction wheel 18 likewise at machine speed or preferably at a speed above it. The friction wheel 18 is seated on a shaft 19, which is arranged in bearings in the left side wall 1, which are not specified in any more detail. On the left end of the shaft 19, a pulley 20 is wound, which is partially wrapped around by a flat belt 21, which is guided at its upper end around a further pulley 22 which sits on the elongated pin 4 of the stationary roller 3. Thus, the pivotable roller 15 can be driven directly from the stationary roller 3.

Die in den Fig. 1 und 2 gezeigte Stellung der verschwenkbaren Walze 15, bei der das Reibrad 18 die Walze 15 anzutreiben vermag, wird durch einen Sperrklinkenmechanismus 24, 25 fixiert. Die auf der Welle 11 drehfest angeordnete Sperrklinke 24 liegt an einer verschwenkbaren Klinke 25 an, wodurch die die Walze 15 tragenden Hebel 12, 13 abgehalten werden, der Zugkraft einer Feder 23 folgend in Uhrzeigerrichtung zu verschwenken, da sich die Traverse 11 nicht drehen kann.The position of the pivotable roller 15 shown in FIGS. 1 and 2, in which the friction wheel 18 can drive the roller 15, is fixed by a pawl mechanism 24, 25. The pawl 24, which is arranged on the shaft 11 in a rotationally fixed manner, rests on a pivotable pawl 25, as a result of which the levers 12, 13 carrying the roller 15 are prevented from pivoting clockwise following the tensile force of a spring 23, since the cross member 11 cannot rotate.

Wird nun durch eine (nicht gezeigte) Papierbahnüberwachungsvorrichtung ein Bahnriß gemeldet, so erhält ein Elektromagnet 26 ein Steuersignal, wodurch durch dessen Anker der Sperrhebel 25 nach oben gezogen und die Klinke 24 freigegeben wird. Nun vermag die Zugfeder 23 die Hebel 12, 13 in Uhrzeigerrichtung, d. h. nach oben zu verschwenken, sodaß die Walze 15 an die Walze 3 gezogen wird. Gleichzeitig, bzw. zu Beginn der Schwenkbewegung erfolgt die Trennung des Antriebes für die Walze 15, da sich diese beim Verschwenken der Hebel 12, 13 von dem Reibrad 18 löst.If a web break is reported by a paper web monitoring device (not shown), an electromagnet 26 receives a control signal, whereby the armature pulls the locking lever 25 upward and the pawl 24 is released. The tension spring 23 is now capable of the levers 12, 13 in the clockwise direction, i. H. to pivot upwards so that the roller 15 is pulled to the roller 3. At the same time, or at the beginning of the pivoting movement, the drive for the roller 15 is separated, since the roller 15 is released from the friction wheel 18 when the levers 12, 13 are pivoted.

Wie bereits erwähnt, wurde im störungsfreien Betrieb die Walze 15 vorzugsweise mit einer etwas oberhalb der Papierbahngeschwindigkeit liegenden Geschwindigkeit angetrieben, sodaß selbst infolge von unvermeidbaren Reibungsverlusten beim freien Drehen der Walze 15 auf der Welle 10 diese mit einer Umfangsgeschwindigkeit an die Walze 3 anstellbar ist, die mindestens noch so groß wie die Papierbahngeschwindigkeit ist. Sobald die Walze 15 an die Walze 3 angestellt ist, wird die zwischen den Walzen 3, 15 durchlaufende, aus dem letzten Druckwerk kommende Papierbahn A erfaßt und festgeklemmt. Nach Anlage der Walze 15 an die Walze 3 wird die Walze 15 dann von der permanent angetriebenen Walze 3 her angetrieben. Die Walzen 3, 15 können kunststoff- oder gummibeschichtet sein.As already mentioned, in trouble-free operation, the roller 15 was preferably driven at a speed slightly above the paper web speed, so that even as a result of unavoidable frictional losses when the roller 15 rotated freely on the shaft 10, it could be set at a peripheral speed on the roller 3 which at least as high as the paper web speed. As soon as the roller 15 is placed against the roller 3, that between the rollers 3, 15 continuous paper web A coming from the last printing unit is gripped and clamped. After the roller 15 abuts the roller 3, the roller 15 is then driven by the permanently driven roller 3. The rollers 3, 15 can be plastic or rubber coated.

Durch die Wahl der Geschwindigkeitsverhältnisse, d. h. der Umfangsgeschwindigkeiten der Walzen 3, 15 im Verhältnis zu der Papierbahngeschwindigkeit, kann unter Berücksichtigung der Ansprechgeschwindigkeit der Fangvorrichtung festgelegt werden, daß die aus dem letzten Druckwerk kommende Druckträgerbahn A durch das Klemmwalzenpaar 3, 15 voll nachgezogen, d. h. abgeführt wird, sodaß die Papierbahn sich nach einem Riß nicht um die Zylinder des letzten Druckwerkes aufwickeln kann, was zu einer Beschädigung desselben führen würde. Bekanntlich neigen insbesondere Offset-Rotationsdruckmaschinen dazu, bei einem Bahnriß, der häufig im nachgeschalteten Trockner auftritt, das abgerissene Ende aus dem Trockner herauszuziehen und um die Gummizylinder des letzten Druckwerkes zu wickeln. Dies wird durch die erfindungsgemäße Vorrichtung vermieden, wobei insbesondere die hohe Ansprechgeschwindigkeit bei schnellaufenden Maschinen sicherstellt, daß das abgerissene Ende bspw. aus dem Trockner heraus und die, aus dem letzten Druckwerk nachgelieferte Papierbahn um das Klemmwalzenpaar, bzw. um eine der Klemmwalzen herumgewickelt werden, sodaß die Funktionsfähigkeit der Druckwerke erhalten bleibt.By choosing the speed ratios, i.e. H. the circumferential speeds of the rollers 3, 15 in relation to the paper web speed, taking into account the response speed of the catching device, it can be determined that the print carrier web A coming from the last printing unit is fully trailed by the pair of clamping rollers 3, 15, i. H. is discharged, so that the paper web cannot wrap around the cylinders of the last printing unit after a tear, which would lead to damage to the latter. As is known, offset rotary printing machines in particular tend to pull the torn end out of the dryer in the event of a web break that frequently occurs in the downstream dryer and to wind it around the rubber cylinders of the last printing unit. This is avoided by the device according to the invention, in particular the high response speed in high-speed machines ensuring that the torn end, for example, out of the dryer and the paper web supplied from the last printing unit are wound around the pair of pinch rollers or around one of the pinch rollers, so that the functionality of the printing units is preserved.

Im beschriebenen Ausführungsbeispiel wurde im störungsfreien Zustand die verschwenkbare Walze 15 durch ein Reibrad 18 angetrieben. Es versteht sich, daß anstelle eines Reibrades auch ein Zahnrad verwendet werden kann, das dann mit einem, auf dem Achszapfen der verschwenkbaren Walze aufziehbaren Zahnrad kämmen könnte. Außerdem kann anstelle des verwendeten Flachriemens 21 auch ein anderer Antrieb, bspw. ein Zahnradantrieb oder ein Zahnriemen, eingesetzt werden.

Figure imgb0001
In the exemplary embodiment described, the pivotable roller 15 was driven by a friction wheel 18 in the fault-free state. It goes without saying that a gearwheel can also be used instead of a friction wheel, which could then mesh with a gearwheel that can be pulled up on the journal of the pivotable roller. In addition, instead of the flat belt 21 used, another drive, for example a toothed wheel drive or a toothed belt, can be used.
