The sheet-pick-up elements are linearly guided by means of guide bars (1) of guide-rails between the transfer position and the delivery position.

Description

Die Erfindung bezieht sich auf eine Vorrichtung für den Antrieb eines Vorgreifers zum Einzeltransport von Bogen von einem Anlegetisch zu einem Greifersystem eines weiterführenden Zylinders, mit einem oder mehreren Bogenerfassungselementen, die zwischen einer Übernahmeposition am Anlegetisch und einer Übergabeposition am Greifersystem hin- und herbewegbar antreibbar sind, wobei durch die Bogenerfassungselemente der vordere Bereich des Bogens in der Übernahmeposition am Anlegetisch erfaßbar und zur Übergabeposition am Greifersystem des weiterführenden Zylinders transportierbar ist.The invention relates to a device for driving a pre-gripper for the single transport of sheets from one feed table to one Gripper system of a further cylinder, with one or more Sheet detection elements between a takeover position on Feed table and a transfer position on the gripper system can be moved back and forth are drivable, whereby by the sheet detection elements front area of the sheet in the transfer position on the feed table detectable and to the transfer position on the gripper system of the continuing Cylinder is transportable.

Bei einer derartigen Vorrichtung ist es bekannt, den Vorgreifer an einem Ende eines Schwinghebels anzuordnen, welcher auf einer ortsfesten Schwingachse angeordnet ist. Über eine am Schwinghebel im Bereich des Vorgreifers angelenkte Koppel ist der Schwinghebel motorisch antreibbar. Durch den Schwinghebel führt der Vorgreifer auf seinem Bewegungsweg eine Schwenkbewegung durch, was zu einer Bogenkrümmung führt. Diese Bogenkrümmung erzeugt eine passerschädliche Deformation des Bogens. In such a device it is known to attach the pre-gripper to one Arrange end of a rocker arm, which on a stationary Swing axis is arranged. Via one on the rocker arm in the area of the pre-gripper coupling, the rocker arm can be driven by a motor. The pre-gripper guides on its path of movement through the rocker arm a swivel motion through, resulting in an arch curve leads. This curvature creates a deformation that is harmful to the passport of the bow.

Aufgabe der Erfindung ist es daher eine Vorrichtung der eingangs genannten Art zu schaffen, durch die die Bogen in exakter Lage dem Greifersystem des weiterführenden Zylinders übergebbar sind.The object of the invention is therefore a device of the aforementioned To create the way by which the sheet is in the exact position of the gripper system of the further cylinder can be transferred.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das oder die Bogenerfassungselemente linear geführt zwischen der Übernahmeposition und der Übergabeposition bewegbar antreibbar sind.This object is achieved in that the or Sheet detection elements guided linearly between the takeover position and the transfer position are movably drivable.

Da nunmehr die Bogen unter Vermeidung jeglicher Krümmung und damit passerschädlicher Deformation an das Greifersystem des weiterführenden Zylinders übergeben werden, erfolgt diese Übergabe mit hoher Exaktheit.Since now the bend avoiding any curvature and thus Deformation damaging to the gripper system of the continuing Cylinders are handed over, this handover takes place with great accuracy.

Eine sichere Linearführung der Bogen wird dadurch erreicht, daß das oder die Bogenerfassungselemente auf parallel zur Bewegungsbahn des Bogens vom Anlegetisch zum weiterführenden Zylinder sich erstreckenden Führungselementen bewegbar angeordnet sind.A safe linear guidance of the sheets is achieved in that the or the sheet detection elements parallel to the path of movement of the sheet extending from the feed table to the further cylinder Guide elements are movably arranged.

In einfacher Ausbildung können dabei die Führungselemente Führungsstangen oder Führungsschienen sein.In simple training, the guide elements can guide rods or guide rails.

Sind die Bogenerfassungselemente mittels Kugelumlaufeinheiten, Rollenumlaufeinheiten oder Flachkäfigführungen auf den Führungselementen bewegbar geführt, so werden nur geringe Antriebskräfte zum Bewegungsantrieb der Bogenerfassungselemente benötigt.Are the sheet detection elements by means of ball circulation units, roller circulation units or flat cage guides on the guide elements movably guided, so only small driving forces become motive power the sheet detection elements needed.

Eine einfach aufgebaute Möglichkeit zum Antrieb der Bogenerfassungselemente besteht darin, daß die Bogenerfassungselemente von einer Schwingenmechanik bewegbar antreibbar sind.A simply constructed way to drive the sheet detection elements is that the sheet detection elements from a Swing mechanism are drivable.

Dazu kann die Schwingenmechanik eine sich etwa in Bewegungsrichtung der Bogenerfassungselemente erstreckende Schwinge aufweisen, deren eines Ende um eine parallel zur Drehachse des Zylinders erstreckende Achse schwenkbar am Bogenerfassungselement und deren anderes Ende an einem eine Bewegung in Erstreckungsrichtung der Bewegungsbahn der Bogenerfassungselemente ausführenden Antriebselement angelenkt ist.For this purpose, the swing arm mechanism can move approximately in the direction of movement of the sheet detection elements have extending rocker, the one end about a parallel to the axis of rotation of the cylinder Swivel axis on the sheet detection element and the other end a movement in the direction of extension of the movement path articulated the drive element executing sheet detection elements is.

Ist dabei das Antriebselement eine um eine sich parallel zur Drehachse des Zylinders erstreckende Kurbelachse drehbar antreibbare Kurbel, an der die Schwinge in einem den Bewegungsweg der Bogenerfassungselemente bestimmenden Abstand zur Kurbelachse angelenkt ist, so ermöglicht dies eine kostengünstige Verwendung eines Elektromotors, insbesondere eines nur in eine Richtung drehenden Elektromotors, als einfachen Drehantrieb. If the drive element is one about a parallel to the axis of rotation of the cylinder extending crank axis rotatably drivable crank which the swing arm in a the path of movement of the sheet detection elements determining distance to the crank axis is articulated, so allows this is an inexpensive use of an electric motor, in particular of a one-way rotating electric motor, as a simple one Rotary drive.

Eine andere, ebenfalls einfach aufgebaute Möglichkeit zum Antrieb der Bogenerfassungselemente besteht darin, daß das Antriebselement an einem um eine zur Drehachse des Zylinders parallele Schwenkhebelachse schwenkbaren Schwenkhebel angelenkt ist, der in einem Abstand zur Schwenkhebelachse an der Umlaufkontur eines drehbar antreibbaren Exzenters von diesem schwenkbar antreibbar in Anlage ist.Another, also simply constructed possibility to drive the Sheet detection elements is that the drive element on one about a pivot lever axis parallel to the axis of rotation of the cylinder pivotable pivot lever is articulated at a distance from Swivel lever axis on the circumferential contour of a rotatably drivable eccentric of this is pivotally driven in the system.

Zur Reduzierung der erforderlichen Antriebskräfte kann dabei an dem Schwenkhebel eine Rolle frei drehbar gelagert sein, über deren radial umlaufende Kontur der Schwenkhebel an dem Exzenter in Anlage ist.To reduce the required driving forces, the Swivel lever a roller can be freely rotated, over the radial circumferential contour of the swivel lever is in contact with the eccentric.

Auf einen separaten Drehantrieb des Exzenters kann dann verzichtet werden, wenn der Exzenter um die Drehachse des Zylinders von dieser drehbar antreibbar angeordnet ist.A separate rotary drive for the eccentric can then be dispensed with when the eccentric about the axis of rotation of the cylinder of this is rotatably driven.

Eine Dritte Antriebsmöglichkeit der Bogenerfassungselemente besteht darin, daß die Bogenerfassungselemente von einem Ketten-, Seil- oder Riemenantrieb bewegbar antreibbar sind, wobei die Kette, das Seil oder der Riemen sich parallel zu den Führungselementen erstreckt und in Richtung seiner Erstreckung bewegbar antreibbar ist sowie die Bogenerfassungselemente mit der Kette, dem Seil oder dem Riemen verbunden sind. A third possibility for driving the sheet detection elements is in that the sheet detection elements of a chain, rope or Belt drive are movably driven, the chain, the rope or the belt extends parallel to the guide elements and in Direction of its extension is drivable and the sheet detection elements connected to the chain, the rope or the strap are.

Dabei ist vorzugsweise die Kette, das Seil oder der Riemen endlos ausgebildet und um Umlenkrollen im Bereich der Enden der Führungselemente geführt.The chain, the rope or the belt is preferably endless and around pulleys in the area of the ends of the guide elements guided.

Zum Antrieb kann eine der Umlenkrollen eine Antriebsrolle bilden.One of the deflection rollers can form a drive roller for driving.

Weitere Möglichkeiten zum Antrieb der Bogenerfassungselemente können darin bestehen, daß die Bogenerfassungselemente von einem pneumatischen oder einem elektrischen Linearantrieb antreibbar sind.Other options for driving the sheet detection elements can consist in that the sheet detection elements by a pneumatic or an electric linear drive can be driven.

Da an Bogenanlegern meist bereits eine Unterdruckquelle vorhanden ist, kann diese zusätzlich dazu verwendet werden, daß auf einfache Weise die Bogenerfassungselemente mit Unterdruck beaufschlagbare Sauger sind, durch die die Bogen erfaßbar sind.Since a vacuum source is usually already available on sheet feeders, this can be used in addition to that in a simple manner the sheet detection elements can be vacuumed through which the sheets can be detected.

Werden die Bogenerfassungselemente von einer eigenen Unterdruckquelle versorgt, so kann diese mit geringer Leistung als z.B. kleines Gebläse ausgebildet sein.The sheet detection elements from a separate vacuum source can be supplied with less power than e.g. small blower be trained.

Eine andere mechanisch einfach aufgebaute Art der Bogenerfassungselemente besteht darin, daß die Bogenerfassungselemente eine Greiferauflage besitzen, auf die der zu fördernde Bogen mit seinem in Förderrichtung vorderen Bereich durch einen Greifer beaufschlagbar ist, wobei durch den Greifer der Bogen in der Übernahmeposition des Bogenserfassungselements erfaßbar und in der Übergabeposition freigebbar ist.Another mechanically simple type of sheet detection elements is that the sheet detection elements a gripper pad own, on which the sheet to be conveyed with its in the conveying direction front area can be acted upon by a gripper, wherein by the gripper the sheet in the takeover position of the sheet detection element is detectable and can be released in the transfer position.

Zum Antrieb des Greifers kann der Greifer an einem Ende eines um eine zur Achse des Zylinders parallele Achse schwenkbaren Hebels angeordnet sein, der an seinem anderen Ende von einer Kulisse derart schwenkbar beaufschlagbar ist, daß der Greifer zur Auflage auf der Greiferauflage bzw. zum Abheben von der Greiferauflage schwenkbar antreibbar ist.To drive the gripper, the gripper can be at one end by one to the axis of the cylinder parallel axis pivotable lever arranged be so pivotable at its other end from a backdrop It can be acted upon by the gripper to rest on the gripper support or is pivotally driven to lift off the gripper pad.

Tragen die Bogenerfassungselemente Vordermarken, so erfolgt die Ausrichtung der Bogen in Förderrichtung erst auf dem weiterfördernden Element und vermeidet so Lagefehler bei der Übergabe vom Bogenanleger zur Vorrichtung.If the sheet detection elements carry front marks, the alignment is carried out the sheet in the conveying direction only on the conveying element and thus avoids position errors when transferring from the sheet feeder to the device.

Zur Reduzierung der Bauteile können dabei Greifer und Vordermarke eine Baueinheit oder ein Bauteil bilden.To reduce the number of components, the gripper and front marker can be one Form a unit or a component.

Sind die Bogenerfassungselemente parallel zur Achse des Zylinders bewegbar antreibbar, so kann damit auch eine Seitenausrichtung der Bogen durchgeführt werden. Are the sheet detection elements movable parallel to the axis of the cylinder drivable, so it can also be a side alignment of the sheet be performed.

Dies kann dadurch erfolgen, daß durch einen Sensor die seitliche Istposition des Bogens in dessen Übernahmeposition erfaßbar und abhängig von der Abweichung der erfaßten seitlichen Istposition von einer Sollposition die Bogenerfassungselemente nach Erfassung des Bogens quer zur Bogenförderrichtung bewegbar antreibbar sind.This can be done in that the lateral actual position by a sensor of the sheet in its takeover position can be detected and dependent of the deviation of the recorded actual position from a target position the sheet detection elements after detection of the sheet transverse to Sheet conveying direction are drivable.

Die in den Figuren dargestellten Vorrichtungen weisen Führungsstangen 1 auf, die parallel zur Bewegungsbahn 2 eines Bogens 3 von einer Übernahmeposition am Ende des Fördertischs 5 eines Bogenanlegers zur einer Übergabeposition an einem Greifersystem 8 einer Zuführtrommel 7 führt, die um eine Achse 13 drehbar gelagert ist.The devices shown in the figures have guide rods 1 on, parallel to the movement path 2 of a sheet 3 from a takeover position at the end of the conveyor table 5 of a sheet feeder to one Transfer position on a gripper system 8 of a feed drum 7 leads, which is rotatably mounted about an axis 13.

Von dort wird der Bogen 3 einem Druckzylinder 9 zugeführt.From there, the sheet 3 is fed to a printing cylinder 9.

Bei Verzicht auf die Zuführtrommel kann der Bogen 3 in der Übergabeposition auch direkt dem Druckzylinder 9 zugeführt werden.If the feed drum is dispensed with, the sheet 3 can be in the transfer position can also be fed directly to the pressure cylinder 9.

Auf die Förderstangen 1 ist jeweils ein Schiebekörper 11 eines Bogenerfassungselements 10, 10', 10" parallel auf der Führungsstange 1 zur Bewegungsbahn 2 des Bogens 3 bewegbar geführt angeordnet, wobei die Bogenerfassungselemente 10, 10', 10" und deren Bewegungsantriebe der verschiedenen Ausführungsbeispiele unterschiedlich ausgebildet sind.A slide body 11 of a sheet detection element is in each case on the conveyor rods 1 10, 10 ', 10 "parallel to the guide rod 1 to the movement path 2 of the sheet 3 movably guided, the Sheet detection elements 10, 10 ', 10 "and their movement drives different embodiments are designed differently.

In Figur 1 besitzt das Bogenerfassungselement 10 am Schiebekörper 11 einen nicht näher dargestellten Greifer, durch den der vom Bogenanleger ankommende Bogen 3 in der Übernahmeposition 4 an seinem Vorderkantenbereich erfaßt und in der Übergabeposition 6 wieder freigegeben wird.In FIG. 1, the sheet detection element 10 has on the sliding body 11 a gripper, not shown, through which the sheet feeder incoming sheet 3 in the takeover position 4 on its leading edge area detected and released again in the transfer position 6 becomes.

An dem Schiebekörper 11 ist eine zur Achse 13 parallele Achse 14 drehbar angeordnet, durch die der Greifer zwischen seiner Greiferposition und seiner Freigabeposition bewegbar antreibbar ist.An axis 14 parallel to the axis 13 can be rotated on the sliding body 11 arranged by which the gripper between its gripper position and its release position is movably drivable.

Von der Achse 14 ragt ein Hebel 15 radial weg und trägt an seinem freien Ende ein frei drehbar gelagerte Rolle 16. In der dargestellten unteren Schwenkposition des Hebels 15 befindet sich der Greifer in seiner Greiferposition. Gelangt das Bogenerfassungselement 10 auf seinem Weg von der Übernahmeposition 4 in die Übergabeposition 6, so läuft die Rolle 16 auf eine Kulisse 17 auf, die den Hebel 15 in seine obere Schwenkposition verschwenkt und damit über die verschwenkte Achse 14 den Greifer in seine Freigabeposition verschwenkt.A lever 15 projects radially away from the axis 14 and bears on its free one End a freely rotatable roller 16. In the lower shown Pivotal position of the lever 15, the gripper is in its gripper position. The sheet detection element 10 arrives on its way from the transfer position 4 to the transfer position 6, the role runs 16 on a backdrop 17, which the lever 15 in its upper pivot position pivoted and thus the gripper via the pivoted axis 14 pivoted into its release position.

Dadurch kann der Bogen 3 vom Greifersystem 8 der Zuführtrommel 7 oder direkt vom Druckzylinder 9 übernommen werden.As a result, the sheet 3 can be removed from the gripper system 8 of the feed drum 7 or be taken over directly from the printing cylinder 9.

Zum verschiebbaren Antrieb des Bogenerfassungselements 10 auf der Führungsstange 1 ist an dem Schiebekörper 11 eine Schwinge 18 mit ihrem einen Ende angelenkt, die sich etwa in Bewegungsrichtung des Bogenerfassungselements 10 erstreckt. Mit ihrem anderen Ende ist die Schwinge 18 an einem Schwenkhebel 19 angelenkt, der mit seinem einen Ende um eine Achse 13 des Zylinders parallele Schwenkhebelachse 20 schwenkbar angelenkt ist.For slidably driving the sheet detection element 10 on the Guide rod 1 is on the sliding body 11 a rocker 18 with her hinged one end, which is approximately in the direction of movement of the sheet detection element 10 extends. With its other end it is Swing arm 18 hinged to a pivot lever 19, the one with his End pivot axis 20 parallel to an axis 13 of the cylinder is pivotally articulated.

In einem Abstand zur Schwenkhebelachse 20 trägt der Schwenkhebel 19 eine frei drehbare Rolle 21, über deren umlaufende Kontur der Schwenkhebel 19 an der Umlaufkontur 22 eines auf der Achse 13 mit der Zuführtrommel 7 drehfest verbundenen Exzenters 23 schwenkbar antreibbar in Anlage ist.The pivot lever 19 bears at a distance from the pivot lever axis 20 a freely rotatable roller 21, over the circumferential contour of the pivot lever 19 on the peripheral contour 22 one on the axis 13 with the feed drum 7 non-rotatably connected eccentric 23 pivotally driven in Facility is.

Durch eine fest abgestützte, vorgespannte Feder 24 wird der Schwenkhebel 19 mit seiner Rolle 21 in Anlage an der Umlaufkontur 22 des Exzenters 23 gehalten.By a firmly supported, preloaded spring 24, the pivot lever 19 with its roller 21 in contact with the peripheral contour 22 of the eccentric 23 held.

Bei dem Ausführungsbeispiel der Figur 2 ist in gleicher Weise wie in Figur 1 eine Schwinge 18 mit ihrem einen Ende an dem Schiebekörper 11 angelenkt. Mit dem anderen Ende ist die Schwinge 18 an einer Kurbel 25 in einem den Bewegungsweg des Bogenerfassungselements 10' bestimmenden Abstand zur Kurbelachse 26 angelenkt. Die Kurbel 25 ist um die zur Achse 13 parallele Kurbelachse 26 drehbar antreibbar.In the embodiment of Figure 2 is in the same way as in Figure 1 a rocker arm 18 articulated at one end to the sliding body 11. At the other end, the rocker 18 is on a crank 25 in a determining the path of movement of the sheet detection element 10 ' Distance to the crank axis 26 articulated.
