Description

Einrichtung zum Verstellen von Vordermarken für Bogen, die einer Druckmaschine mittels einer Anlegeeinrichtung einzeln zugeführt werden, mit drehfest mit einer Vordermarkenwelle verbundenen Vordermarken, einem ersten und einem zweiten Schwenkteil, das jeweils um eine ortsfeste, beiden Schwenkteilen gemeinsame geometrische Schwenkachse schwenkbar ist und in dem die Vordermarkenwelle jeweils frei drehbar gelagert ist, an den beiden Schwenkteilen angreifenden Stellmitteln zur Lageveränderung der Vordermarkenwelle und einer Schwenkeinrichtung zum Hin- und Herschwenken der Vordermarkenwelle um deren Längsachse.Device for adjusting front marks for sheets, which are fed individually to a printing machine by means of an application device, with front marks rotatably connected to a front mark shaft, a first and a second pivoting part, each of which is pivotable about a fixed geometric pivot axis common to both pivoting parts and in which the Front marker shaft is each freely rotatably mounted, on the two pivoting parts engaging adjusting means for changing the position of the front marker shaft and a pivoting device for pivoting the front marker shaft back and forth about its longitudinal axis.

Eine derartige Einrichtung ist aus der DE-PS 10 94 270 bekannt. Bei dieser bekannten Einrichtung sind die Schwenkteile an Seitenwänden eines Maschinengestells angelenkt, welches auf einer Seite von einem überstehenden Ende der Vordermarkenwelle durchdrungen wird. Dieses überstehende Ende der Vordermarkenwelle trägt einen kurvengesteuerten Hebel. Somit erfolgt die Krafteinleitung zum Hin- und Herschwenken der Vordermarkenwelle um ihre Längsachse an einem Ende der Vordermarkenwelle. Dies kann besonders bei schnellaufenden Druckmaschinen zu Torsions- und Biegeschwingungen der Vordermarkenwelle mit erheblichen Amplituden führen, so daß eine einwandfreie Anlage einer Bogenvorderkante an den Vordermarken nicht gewährleistet ist. Infolge dieser Torsions- und Biegeschwingungen können die Vordermarken in und entgegen der Zuführrichtung der Bogen örtlich in unterschiedlichem Maße über eine Ausrichtstellung hinausschwingen. Dies führt gegebenenfalls zu einer Schrägstellung des Bogens oder zur Beschädigung seiner Vorderkante.Such a device is known from DE-PS 10 94 270. In this known device, the swivel parts are hinged to the side walls of a machine frame, which is penetrated on one side by a protruding end of the front marker shaft. This protruding end of the front brand shaft carries a cam-controlled lever. Thus, the force is applied to pivot the front mark shaft back and forth about its longitudinal axis at one end of the front mark shaft. This can lead to torsional and bending vibrations of the front mark shaft with considerable amplitudes, particularly in the case of high-speed printing presses, so that a perfect contact of a sheet leading edge with the front marks is not guaranteed. As a result of these torsional and bending vibrations, the front marks can oscillate locally in and against the feed direction of the sheets to different degrees beyond an alignment position. This may result in the sheet being tilted or in damage to its leading edge.

Demgemäß besteht die Aufgabe der Erfindung darin, eine gattungsgemäße Einrichtung so auszugestalten, daß bei ihrem Einsatz an schnellaufenden Druckmaschinen Ausrichtfehler und Beschädigungen der Bogenvorderkante so klein wie möglich gehalten werden.Accordingly, the object of the invention is to design a generic device so that alignment errors and damage to the leading edge of the sheet are kept as small as possible when used on high-speed printing presses.

Diese Aufgabe wird erfindungsgemäß mit einer Einrichtung gemäß Anspruch 1 gelöst.This object is achieved with a device according to claim 1.

Bei einem in etwa in der Längsmitte der Vordermarkenwelle erfolgenden Angriff der Schwenkeinrichtung bewirken selbst im Falle von Torsions- und Biegeschwingungen der Vordermarkenwelle über eine Ausrichtstellung hinausschwingende Vordermarken keine ungewollte Schrägstellung eines Bogens, da in diesem Falle gegebenenfalls auftretende Auslenkungen der Vordermarken im wesentlichen symmetrisch zum Angriffspunkt der Schwenkeinrichtung erfolgen.When the swivel device engages approximately in the longitudinal center of the front marker shaft, even in the case of torsional and bending vibrations of the front marker shaft, front brands swinging beyond an alignment position do not cause an undesired inclination of an arc, since in this case any deflections of the front brands which occur occur essentially symmetrically to the point of application Swivel device take place.

Darüber hinaus werden bei gegebenenfalls auftretenden Torsionsschwingungen der Vordermarkenwelle die maximalen Amplituden dieser Schwingungen stark verkleinert.In addition, the maximum amplitudes of these vibrations are greatly reduced in the event of torsional vibrations of the front marker wave.

Schwenkeinrichtungen zum Hin- und Herschwenken der Vordermarkenwelle weisen im allgemeinen einen außerhalb der Längsachse der Vordermarkenwelle gelegenen Kraftangriffspunkt auf. Neben der Einprägung eines Drehmomentes übertragen solche Schwenkeinrichtungen also auch Querkräfte auf die Vordermarkenwelle. Bei den üblicherweise großen Abständen zwischen zwei eine Vordermarkenwelle aufnehmenden Lagern und einem zwischen diesen Lagern befindlichen Kraftangriffspunkt einer Schwenkeinrichtung können die genannten Querkräfte zu beachtlichen Durchbiegungen der Vordermarkenwelle führen. Ein störender Einfluß dieser Durchbiegungen auf die einwandfreie Ausrichtung der Bogen an den Vordermarken, auf die einwandfreie Übergabe ausgerichteter Bogen an nachfolgende mit Greifern ausgestattete Bogentransfermittel und auf eine schonende Handhabung der Bogenvorderkante kann zwar dadurch verhindert werden, daß die Vordermarkenwelle mittels eines zusätzlichen Lagers, vorzugsweise in unmittelbarer Nähe des Kraftangriffspunktes abgestützt wird. Hiermit kann zwar Durchbiegungen der Vordermarkenwelle entgegengewirkt werden, doch ein derartiges zusätzliches Lager würde ohne weitergehende Maßnahmen eine Verstellmöglichkeit zur Lageveränderung der Vordermarkenwelle ausschließen.Pivoting devices for pivoting the front mark shaft back and forth generally have a force application point located outside the longitudinal axis of the front mark shaft. In addition to impressing a torque, such swivel devices also transmit lateral forces to the front mark shaft. Given the usually large distances between two bearings receiving a front mark shaft and a force application point of a pivoting device located between these bearings, the cited transverse forces can lead to considerable deflections of the front mark shaft. A disturbing influence of these deflections on the perfect alignment of the sheets on the front marks the flawless transfer of aligned sheets to subsequent sheet transfer means equipped with grippers and careful handling of the leading edge of the sheet can be prevented by supporting the front mark shaft by means of an additional bearing, preferably in the immediate vicinity of the force application point. With this, deflections of the front mark shaft can be counteracted, but such an additional bearing would preclude an adjustment possibility for changing the position of the front mark shaft without further measures.

Zur Beibehaltung einer Verstellmöglichkeit der Vordermarkenwelle ist daher gemäß der Erfindung ein den Lageveränderungen der Vordermarkenwelle folgendes zusätzliches Stützlager vorgesehen.In order to maintain the possibility of adjusting the front marker shaft, an additional support bearing that follows the changes in position of the front marker shaft is therefore provided according to the invention.

Die gemäß der Erfindung vorgesehene Kombination ermöglicht also, daß die neben den dargelegten günstigen Eigenschaften eines Angriffs der Schwenkeinrichtung in etwa in der Längsmitte der Vordermarkenwelle bestehenden ungünstigen Auswirkungen in Richtung einer Verbiegung der Vordermarkenwelle unterdrückt werden und gleichzeitig eine freie Verstellbarkeit der Vordermarkenwelle mittels der Schwenkteile beibehalten werden kann.The combination provided according to the invention thus enables the unfavorable effects existing in the direction of a bending of the front mark shaft in addition to the described favorable properties of an attack of the swivel device approximately in the longitudinal center of the front mark shaft, and at the same time maintain a free adjustability of the front mark shaft by means of the swivel parts can.

Die Erfindung ist nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with reference to an embodiment shown in the drawings.

Die Vordermarken 1 sind mittels Stiften 11 drehfest mit der Vordermarkenwelle 2 verbunden. Zur Vereinfachung der Darstellung sind von den über die Länge der Vordermarkenwelle 2 verteilten Vordermarken 1 nur zwei in der Zeichnung wiedergegeben. Die Vordermarkenwelle 2 ist mittels Pendellagern 3 in je einem Schwenkteil 4 frei drehbar gelagert, wobei diese Pendellager 3 in ein oberes Ende eines jeweiligen Schwenkteils 4 eingesetzt sind. Ein jeweils unteres Ende der Schwenkteile 4 ist über je ein Gelenk 5 mit einer ortsfesten Traverse 6 verbunden, deren Enden an nicht dargestellten Seitenwänden befestigt sind. Die Gelenke 5 bilden eine gemeinsame geometrische Schwenkachse 25 für die Schwenkteile 4 und erlauben deren Schwenkung in und entgegen der Zuführrichtung der Bogen.The front marks 1 are rotatably connected to the front mark shaft 2 by means of pins 11. To simplify the illustration, only two of the front brands 1 distributed over the length of the front brand shaft 2 are shown in the drawing. The front brand shaft 2 is freely rotatably supported in each pivot part 4 by means of self-aligning bearings 3, these self-aligning bearings 3 being inserted into an upper end of a respective swivel part 4. Each lower end of the swivel parts 4 is connected via a joint 5 to a fixed crossmember 6, the ends of which are fastened to side walls (not shown). The joints 5 form a common geometric pivot axis 25 for the pivot parts 4 and allow their pivoting in and against the feed direction of the sheets.

Die jeweilige Schwenklage der Schwenkteile 4 wird durch in Fig. 2 im einzelnen dargestellte Stellmittel definiert. Hierzu ist eine weitere ortsfeste Traverse 7 vorgesehen, die den oberen Enden der Schwenkteile 4 gegenübersteht. Jeweils eine diese Traverse 7 durchgreifende Spannschraube 8 ist in je ein oberes Ende eines Schwenkteils 4 eingeschraubt. Eine unter den Schraubenkopf der Spannschraube 8 eingespannte und gegen die Traverse 7 abgestützte Feder 9 drückt das jeweilige Schwenkteil 4 in Richtung auf die Traverse 7 gegen einen verstellbaren Anschlag, der von einer in der Traverse 7 gelagerten Stellspindel 10 gebildet wird.The respective swivel position of the swivel parts 4 is defined by adjusting means shown in detail in FIG. 2. For this purpose, a further fixed crossbeam 7 is provided which faces the upper ends of the swivel parts 4. One clamping screw 8 passing through this crossmember 7 is screwed into an upper end of a swivel part 4. A spring 9 clamped under the screw head of the tensioning screw 8 and supported against the crossmember 7 presses the respective pivot part 4 in the direction of the crossmember 7 against an adjustable stop which is formed by an adjusting spindle 10 mounted in the crossbar 7.

In Fig. 1 ist der Einfachheit halber lediglich ein dem in der Zeichnung rechten Schwenkteil 4 gegenüberliegendes Teilstück der Traverse 7 und dementsprechend nur eine Stellspindel 10 dargestellt.In FIG. 1, for the sake of simplicity, only a section of the crossmember 7 opposite the right-hand swivel part 4 in the drawing and, accordingly, only one adjusting spindle 10 is shown.

Mittels eines Stiftes 12 ist ein Schwinghebel 13 drehfest mit der Vordermarkenwelle 2 verbunden. Dieser Schwinghebel 13 dient dem Hin- und Herschwenken der Vordermarkenwelle 2 um deren Längsachse und ist gemäß der Erfindung in unmittelbarer Nähe eines zusätzlichen Stützlagers 16 für die Vordermarkenwelle 2 angeordnet. Das der Vordermarkenwelle 2 abgewandte Ende des Schwinghebels 13 ist an eine Kurbelstange 14 eines nicht im einzelnen dargestellten Kurbeltriebs angelenkt, mit welchem die Kurbelstange 14 entsprechend dem Doppelpfeil 15 im Takt der Druckmaschine vor- und zurückbewegt wird.A rocker arm 13 is rotatably connected to the front marker shaft 2 by means of a pin 12. This rocker arm 13 is used to pivot the front mark shaft 2 back and forth about its longitudinal axis and is according to the Invention arranged in the immediate vicinity of an additional support bearing 16 for the front marker shaft 2. The end of the rocker arm 13 facing away from the front marker shaft 2 is articulated to a crank rod 14 of a crank mechanism, not shown in detail, with which the crank rod 14 is moved back and forth in accordance with the double arrow 15 in time with the printing press.

Zwischen den beiden Schwenkteilen 4 ist die Vordermarkenwelle 2 in wenigstens einem zusätzlichen Stützlager 16 aufgenommen, welches den Lageveränderungen der Vordermarkenwelle 2 folgt, die durch gleichsinnige oder individuelle Verschwenkung der Schwenkteile 4 um die Gelenke 5 mittels der Stellspindeln 10 bewirkt werden können. Das Stützlager 16 nimmt die Vordermarkenwelle 2 in einem in einen Lagerhebel 17 eingesetzten Nadellager 18 frei drehbar auf. Der Lagerhebel 17 ist einerseits mittels eines weiteren Gelenks 24 mit der Traverse 6 verbunden und andererseits an einer Traverse 19 befestigt. Das Gelenk 24 ist hierbei beispielsweise mit einem nicht dargestellten weiteren Pendellager gebildet, dessen Außenring mit der gemeinsamen geometrischen Schwenkachse 25 der Schwenkteile 4 fluchtet, und in dessen Innenring ein mit dem Lagerhebel 17 verbundener Gelenkzapfen eingesteckt ist, so daß der Lagerhebel 17 in begrenztem Maße auch eine Schwenkung um eine gedachte Längsachse desselben ausführen kann. Die Traverse 19 erstreckt sich zwischen den Schwenkteilen 4. Je ein Ende der Traverse 19 ist zwischen je einem oberen und einem unteren Ende eines Schwenkteils 4 gelenkig mit diesem verbunden.Between the two pivoting parts 4, the front marker shaft 2 is received in at least one additional support bearing 16, which follows the changes in position of the front marker shaft 2, which can be brought about by pivoting the pivoting parts 4 in the same direction or individually about the joints 5 by means of the adjusting spindles 10. The support bearing 16 receives the front marker shaft 2 in a needle bearing 18 inserted into a bearing lever 17 so that it can rotate freely. The bearing lever 17 is connected on the one hand by means of a further joint 24 to the cross member 6 and on the other hand is fastened to a cross member 19. The joint 24 is formed here, for example, with a further self-aligning bearing, not shown, whose outer ring is aligned with the common geometric pivot axis 25 of the pivot parts 4, and in the inner ring of which a joint pin connected to the bearing lever 17 is inserted, so that the bearing lever 17 also to a limited extent can pivot about an imaginary longitudinal axis of the same. The crossmember 19 extends between the swivel parts 4. Each end of the crossmember 19 is articulated between an upper and a lower end of a swivel part 4.

Eine entsprechende gelenkige Verbindung ist in Fig. 3 dargestellt. Dabei ist in den Schwenkteilen 4 je ein Pendellager 20 eingesetzt. In je ein solches Pendellager 20 ist ein Bolzen 21 eingesteckt, der in jeweils eine stirnseitige Bohrung 22 der Traverse 19 eingepaßt und gegenüber dieser mittels einer Feststellschraube 23 lagegesichert ist.A corresponding articulated connection is shown in Fig. 3. In this case, a self-aligning bearing 20 is used in the swivel parts 4. In each such a self-aligning bearing 20, a pin 21 is inserted, which fits into a respective end bore 22 of the cross member 19 and is secured against this by means of a locking screw 23.

Die solchermaßen den Lageveränderungen der Schwenkteile 4 und damit jenen der Vordermarkenwelle 2 folgende Traverse 19 ist mit dem Lagerhebel 17 über eine Schraubverbindung 26 starr verbunden. Das in den Lagerhebel 17 eingesetzte Nadellager 18 folgt damit einerseits den Lageveränderungen der Vordermarkenwelle 2 und bildet gleichzeitig eine wirksame Abstützung der Vordermarkenwelle 2 gegen Durchbiegungen, die andernfalls durch den Angriff des Schwinghebels 13 hervorgerufen würden.The traverse 19 which follows the changes in position of the swivel parts 4 and thus those of the front marker shaft 2 is rigidly connected to the bearing lever 17 via a screw connection 26. The needle bearing 18 inserted in the bearing lever 17 thus follows on the one hand the changes in position of the front mark shaft 2 and at the same time forms an effective support of the front mark shaft 2 against deflections which would otherwise be caused by the attack of the rocker arm 13.

Für den Fall einer ungleichen Verstellung der beiden Schwenkteile 4 ist auch die gelenkige Verbindung zwischen der Kurbelstange 14 und dem Schwinghebel 13 so ausgebildet, daß letzterer ebenfalls in begrenztem Maße auch eine Schwenkung um dessen gedachte Längsachse ausführen kann.In the event of an unequal adjustment of the two pivoting parts 4, the articulated connection between the crank rod 14 and the rocking lever 13 is also designed such that the latter can also pivot to a limited extent about its imaginary longitudinal axis.
