Description

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Ausrichtung von Bogen.The invention relates to a device and a method for aligning sheets.

Aus der EP 01 20 348 A2 ist eine Vorrichtung und ein Verfahren zur Ausrichtung von Bogen bekannt Die Ausrichtung der Vorderkante der Bogen erfolgt dabei in der Art, dass die schuppenförmig der Vorrichtung zugeführten Bogen mit einer Fördergeschwindigkeit an einen Ausrichtzylinder in der Vorrichtung zugeführt werden, die zumindest geringfügig größer als die Umfangsgeschwindigkeit des Ausrichtzylinders ist. Am Umfang des Ausrichtzylinders sind Vordermarken angeordnet, an denen die Vorderkante der Bogen zur Anlage bringbar ist. Auf Grund der Relativgeschwindigkeiten zwischen Bogen und Vordermarken wird die Vorderkante der Bogen an den Vordermarken zumindest geringfügig abgebremst und dadurch die Vorderkante des Bogens ausgerichtet. Nach der Ausrichtung der Vorderkante des Bogens wird der Bogen im Bereich der Vorderkante durch Anlegen eines Unterdruckes an einer Saugleiste fixiert, so dass der Bogen den Ausrichtzylinder, auf Grund des fortlaufenden rotatorischen Antriebs des Ausrichtzylinders, an dessen Umfang umschlingt. Nach der Ausrichtung der Vorderkante des Bogens und vor der Übergabe des Bogens an eine nachgeordnete Vorrichtung wird der Seitenversatz einer Seitenkante des Bogens mit Hilfe einer Messeinrichtung vermessen. In Abhängigkeit des Messergebnisses wird die Saugleiste, an der die Vorderkante des Bogens fixiert ist, axial in Richtung der Rotationsachse des Ausrichtzylinders linear verstellt, um dadurch die Seitenkante des Bogens entsprechend der gewünschten Sollausrichtung auszurichten. Im Ergebnis wird dadurch erreicht, dass der Bogen sowohl gegenüber der Vorderkante als auch gegenüber einer Seitenkante lagerichtlg an eine nachgeordnete Vorrichtung, beispielsweise eine Bogendruckmaschine, übergeben werden kann. EP 01 20 348 A2 describes an apparatus and a method for aligning Known sheet The alignment of the leading edge of the sheet is done in such a way that the scale-shaped sheet fed to the device at a conveying speed can be fed to an alignment cylinder in the device, at least slightly is greater than the peripheral speed of the alignment cylinder. At the extent of Alignment cylinders have front marks on which the leading edge of the sheet can be brought to the plant. Due to the relative speeds between bow and Front marks are at least the leading edge of the sheets on the front marks Slightly slowed down and thereby aligned the front edge of the sheet. After Alignment of the leading edge of the sheet becomes the sheet in the area of the leading edge fixed by applying a negative pressure to a squeegee, so that the bow the Alignment cylinder, due to the continuous rotary drive of the Alignment cylinder wrapped around its circumference. After aligning the leading edge of the sheet and before the sheet is transferred to a downstream device the lateral offset of a side edge of the sheet using a measuring device measured. Depending on the measurement result, the squeegee on which the Front edge of the sheet is fixed axially in the direction of the axis of rotation Alignment cylinder adjusted linearly, thereby corresponding to the side edge of the sheet the desired target alignment. The result of this is that the sheet opposite both the front edge and a side edge correct position to a downstream device, for example a sheet-fed printing machine, can be handed over.

Aus der DE 23 13 150 C3 ist eine Vorrichtung zur Bogenzuführung für eine Bogenrotationsdruckmaschine bekannt, bei der die Bogen geschuppt auf einem Anlegetisch zu der Vorrichtung hin und von der Vorrichtung weg gefördert werden. Zur Förderung der flächig auf dem Anlegetisch aufliegenden Bogen wird die Verwendung von Saugwalzen beschrieben, an deren gesamten Umfang Ausnehmungen vorgesehen sind. Durch Anlegen eines Unterdruckes kann der Bogen am Umfang der Saugwalze fixiert werden. Die Saugwalze ist dabei derart in einer Ausnehmung des Anlegetisches angeordnet, dass die Bogen flächig auf dem Anlegetisch aufliegend und tangential am Umfang der Saugwalze anliegend antreibbar sind. Dadurch wird erreicht, dass die Bogen mit der Saugwalze jeweils nur in einem linienförmigen Kontaktbereich in Berührung kommen, wobei die Antriebskräfte von der Saugwalze im linienförmigen Kontaktbereich reibschlüssig auf den Bogen übertragen werden. Ein Umschlingung der Saugwalzen durch die Bogen ist somit nicht erforderlich.From DE 23 13 150 C3 is a device for sheet feeding for a Sheet-fed rotary printing machine known in which the sheets are shingled on a Feed table to the device and be promoted away from the device. to The use of is used to promote the sheet lying flat on the feed table Suction rolls are described, on the entire circumference of which recesses are provided. The sheet can be fixed on the circumference of the suction roll by applying a negative pressure become. The suction roller is in such a way in a recess of the feed table arranged that the sheets lie flat on the feed table and tangentially on Extent of the suction roller are driven. This ensures that the bow in contact with the suction roller only in a linear contact area come, the driving forces from the suction roller in the linear contact area frictionally transferred to the sheet. A loop around the suction rolls through the bow is therefore not necessary.

Aus der WO 97/35795 A1 ist eine Vorrichtung mit einer Saugtrommel bekannt, an deren Umfang die zu transportierenden Bogen durch Anlegen eines Unterdruckes reibschlüssig fixierbar sind. Der Antrieb der Saugtrommel ist dabei derart ausgebildet, dass die Drehzahl und/oder der Drehwinkel der Saugtrommel durch einen unabhängigen Elektromotor nach vorgegebenen Bewegungsgesetzen geregelt werden kann.From WO 97/35795 A1 a device with a suction drum is known, at the Scope of the sheets to be transported by applying a vacuum are fixable. The drive of the suction drum is designed such that the Speed and / or the angle of rotation of the suction drum by an independent Electric motor can be regulated according to predetermined laws of motion.

Aus der DE-AS 20 46 602 ist eine Bogenzuführung für Druckmaschinen bekannt, bei der der seitliche Versatz einer Seitenkante der Bogen relativ zu einer Sollausrichtung mit einer Messeinrichtung feststellbar ist. Zur Ausrichtung der Seitenkante des Bogens kann dabei in Abhängigkeit vom Messergebnis ein Ausrichtzylinder, an dessen Umfang der Bogen fixiert ist, axial in Richtung seiner Rotationsachse verstellt werden.From DE-AS 20 46 602 a sheet feed for printing machines is known in which the lateral offset of a side edge of the sheet relative to a target orientation with a measuring device can be determined. Can align the side edge of the sheet depending on the measurement result, an alignment cylinder, on the circumference of which Bow is fixed, can be adjusted axially in the direction of its axis of rotation.

Aus der EP 07 16 287 A2 ist eine berührungslos arbeitende Vorrichtung zum Messen der Lage von Bogen bekannt, bei der die Seitenkanten der Bogen mittels eines optischen Systems vermessen werden kann.EP 07 16 287 A2 describes a non-contact device for measuring the Location of sheets known in which the side edges of the sheet by means of an optical Systems can be measured.

Die DE 42 39 732 A1 zeigt eine Vorrichtung zum Ausrichten von Bogen, bei dem die Bogen zuerst mittels eines Bändersystems vorausgerichtet und anschließend mittels Saugwalze fein ausgerichtet werden.DE 42 39 732 A1 shows a device for aligning sheets in which the Sheets are first pre-aligned using a belt system and then using Suction roller can be finely aligned.

Die US 5 078 384 A offenbart eine Vorrichtung zum Ausrichten von Bogen mittels zweier einzeln angetriebenen Räder, die von einem ersten die Ankunft des Bogens signalisierenden Sensor und zwei die Schräglage des Bogens erfassende Sensoren angesteuert werden.US 5 078 384 A discloses a device for aligning sheets by means of two individually driven wheels by a first the arrival of the bow signaling sensor and two sensors detecting the inclined position of the bow can be controlled.

Die EP 0 047 455 A1 beschreibt eine Vorrichtung zur Ausrichtung von Bogen, bei der mehrere Ausrichtelemente in Abhängigkeit von hintereinander angeordneten Sensoren betätigt werden.EP 0 047 455 A1 describes a device for aligning sheets in which several alignment elements depending on sensors arranged one behind the other be operated.

Die WO 98/18053 A1 und die US 5 697 609 A zeigen Vorrichtungen zum Ausrichten von Bogen mit mindestens drei hintereinander angeordneten Sensoren.WO 98/18053 A1 and US 5 697 609 A show devices for aligning Sheet with at least three sensors arranged one behind the other.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren zur Ausrichtung von Bogen zu schaffen.The invention has for its object a device and a method for To create alignment of arches.

Die Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1 oder 4 gelöst.The object is achieved by the features of claims 1 or 4.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass der Kantenversatz des Bogens vor, während und nach der Ausrichtung mit insgesamt vier sensoren gemessen werden kann, wobei die Messergebnisse der verschiedenen Sensoren einerseits zur Ansteuerung der verschiedenen Stellorgane, insbesondere des Ausrichtzylinders, mit denen die Ausrichtung des Bogens beeinflussbar ist, verwendet werden kann und zugleich eine im wesentlichen durchgängige Kontrolle und/oder Dokumentation der Bogenausrichtung gewährleistet ist. Insbesondere kann durch die Messung der Bogenausrichtung während der unterschiedlichen Phasen der Förderung eine Vorausrichtung der Bogen vor der eigentlichen Feinausrichtung am Ausrichtzylinder ermöglicht werden. Außerdem ist eine Endkontrolle der Bogenausrichtung vor der Übergabe an nachgeordnete Vorrichtungen, beispielsweise einen Transferzylinder, möglich, so dass beispielsweise bei einer Überschreitung der zulässigen Lagetoleranzen eine Übergabe nicht erfolgt und der entsprechende Bogen ausgesteuert wird. The advantages that can be achieved with the invention are, in particular, that the Edge offset of the sheet before, during and after alignment with a total of four sensors can be measured, with the measurement results of different Sensors on the one hand to control the various actuators, in particular the Alignment cylinder with which the alignment of the sheet can be influenced is used can be and at the same time an essentially continuous control and / or Documentation of the sheet alignment is guaranteed. In particular, through the Measurement of the arch alignment during the different phases of the promotion a pre-alignment of the sheets before the actual fine alignment on the alignment cylinder be made possible. There is also a final check of the sheet alignment before Transfer to downstream devices, for example a transfer cylinder, possible, so that, for example, if the permissible position tolerances are exceeded a transfer did not take place and the corresponding sheet was driven.

Wird in der Vorrichtung zusätzlich noch ein fünfter Sensor vorgesehen, der in Förderrichtung der Bogen hinter dem dritten Sensor angeordnet ist, so kann der Kantenversatz der Vorderkante des Bogens auch noch während der Ausrichtung des Bogens durch den Ausrichtzylinder gemessen und kontrolliert werden, so dass die Ausrichtung in Abhängigkeit des Messergebnisses des fünften Sensors noch durch entsprechende Stellbewegung des Ausrichtzylinders korrigierbar ist.If a fifth sensor is additionally provided in the device, the sensor in The conveying direction of the sheet is arranged behind the third sensor, so the Edge offset of the leading edge of the sheet even during the alignment of the Arc measured and checked by the alignment cylinder so that the Alignment depending on the measurement result of the fifth sensor corresponding adjustment movement of the alignment cylinder can be corrected.

Ein weiterer Vorteil der Erfindung besteht darin, dass zur Ausrichtung der Kanten des Bogens eine neuartige Funktionsweise des Stellorgans vorgeschlagen wird. Anders als bei den bekannten Ausrichtzylindern, an deren Umfang Vordermarken vorgesehen sind, so dass durch eine Relativgeschwindigkeit zwischen Vordermarken und Bogenkante eine Ausrichtung des Bogens erreicht wird, kann der Bogen nach der Lehre der vorliegenden Erfindung dadurch ausgerichtet werden, dass am Ausrichtzylinder zumindest zwei Zylinderelemente vorgesehen sind, die jeweils am Bogen zur Anlage kommen können und relativ zueinander gegenüber der Rotationsachse des Ausrichtzylinders verstellbar sind. Mit anderen Worten bedeutet dies, dass die Zylinderelemente während des Kontakts am Bogen sich mit unterschiedlichen Absolutgeschwindigkeiten bewegen, wobei durch den Kontakt zwischen Zylinderelementen und Bogen diese Geschwindigkeitsdifferenz auf den Bogen übertragen wird. Aufgrund der Geschwindigkeitsdifferenz werden die verschiedenen Abschnitte des Bogens während der Anlage am Ausrichtzylinder unterschiedlich weit weitergefördert, so dass durch entsprechende Wahl der Relativgeschwindigkeit zwischen den Zylinderelementen eine gezielte Ausrichtbewegung des Bogens bewirkt werden kann.Another advantage of the invention is that to align the edges of the Arc a new mode of operation of the actuator is proposed. Different to in the known alignment cylinders, on the circumference of which front marks are provided, so that due to a relative speed between the front marks and the sheet edge Alignment of the arch is achieved, the arch can be taught according to the present Invention be aligned in that at least two alignment cylinder Cylinder elements are provided, which can come to rest on the arch and adjustable relative to each other with respect to the axis of rotation of the alignment cylinder are. In other words, this means that the cylinder elements during contact on the arch move at different absolute speeds, whereby by the contact between the cylinder elements and the bow on this speed difference the bow is transferred. Due to the speed difference, the different sections of the sheet during installation on the alignment cylinder promoted to different degrees, so that by appropriate choice of Relative speed between the cylinder elements a targeted alignment movement of the bow can be effected.

In welcher Art die Relativgeschwindigkeit zwischen den Zylinderelementen des Ausrichtzylinders realisiert wird, ist dabei grundsätzlich gleichgültig. Beispielsweise ist es denkbar, dass die Zylinderelemente gemeinsam auf einem Grundkörper mit einer bestimmten Grundgeschwindigkeit umlaufen und zur Ausrichtung des Bogens die Zylinderelemente jeweils relativ zum Grundkörper und damit relativ zum jeweils anderen Zylinderelement verstellt werden können. Auch ist es denkbar, dass die Zylinderelemente jeweils unabhängig voneinander angetrieben werden, wobei dabei zur Förderung der Bogen ohne Ausrichtung der Kanten die Zylinderelemente zueinander synchron, d. h. mit gleichen Antriebsgeschwindigkeiten, angetrieben werden müssen.In what way the relative speed between the cylinder elements of the Alignment cylinder is basically irrelevant. For example it is conceivable that the cylinder elements together on a base body with a certain basic speed and to align the arc Cylinder elements each relative to the base body and thus relative to the other Cylinder element can be adjusted. It is also conceivable that the cylinder elements are each driven independently, thereby promoting the Arch without aligning the edges, the cylinder elements in sync with each other, d. H. With same drive speeds, must be driven.

B. an alignment cylinder 06, which consists essentially of a Drive shaft 07 and two spaced apart on the drive shaft 07 Suction rolls 08; 09 is built, rotatably mounted.

Zum rotatorischen Antrieb des Ausrichtzylinders 06 dient ein Antriebsmotor 11, der gestellfest am zweiten Rahmenteil 02 befestigt ist und dessen Antriebsbewegung über einen Längenausgleich ermöglichende Kupplung 12 auf die Antriebswelle 07 übertragen wird.A drive motor 11 is used for the rotary drive of the alignment cylinder 06 fixed to the frame on the second frame part 02 and its drive movement over transfer a coupling 12 enabling length compensation to the drive shaft 07 becomes.

Am Umfang der Saugwalzen 08; 09 ist jeweils eine Vordermarke 13 befestigt. Ein Bogen 14, der der Vorrichtung 01 aus einer nicht dargestellten Schuppvorrichtung zusammen mit anderen Bogen zugeführt wird, kommt mit einer Relativgeschwindigkeit an den Vordermarken 13 zur Anlage, so dass die Vorderkante des Bogens 14 durch Abbremsen an den Vordermarken 13 ausgerichtet wird. Nach der Ausrichtung der Vorderkante des Bogens 14 wird der Bogen 14 durch Anlegen eines Unterdrucks mit z. B. von 0,2 bis 0,6 bar aus einer Unterdruckquelle in nicht dargestellten Saugkammem an den Saugwalzen 08; 09 fixiert. Damit liegt der Bogen 14 flächig auf einem an der Oberseite des ersten Rahmenteils 03 angeordneten Anlegetisch 16 auf und ist über die Saugwalzen 08; 09 mit dem ersten Rahmenteil 03 kraftschlüssig verbunden.At the circumference of the suction rolls 08; 09 a front mark 13 is attached. An arch 14, the device 01 together with a scale device, not shown other sheet is fed, arrives at a relative speed Front marks 13 to the system, so that the front edge of the sheet 14 by braking is aligned with the front brands 13. After aligning the front edge of the Bow 14, the bow 14 by applying a vacuum with z. B. from 0.2 to 0.6 bar from a vacuum source in suction chambers, not shown, on the suction rolls 08; 09 fixed. Thus, the sheet 14 lies flat on one on the top of the first Frame part 03 arranged feed table 16 and is on the suction rollers 08; 09 with the first frame part 03 non-positively connected.

Während die Saugwalzen 08; 09 weiter umlaufen und dadurch den Bogen 14 in Förderrichtung weiterfördem, kann zur Ausrichtung einer Seitenkante des Bogens 14 das ganze erste Rahmenteil 03 zusammen mit dem Ausrichtzylinder 06 und dem Anlegetisch 16 axial in Richtung der Rotationsachse des Ausrichtzylinders 06 verstellt werden. Dazu dient ein Antriebsmotor 17, der über eine Kupplung 18 eine in einem Festlager 19 gelagerte Kugelgewindespindel 21 antreibt. In der seitlichen Bauteilwandung des ersten Rahmenteils 03 ist eine Gewindemutter 22 befestigt, die mit der Kugelgewindespindel 21 im Eingriff steht, so dass durch Antrieb der Kugelgewindespindel 21 das gesamte erste Rahmenteil 03 in den Linearführungen 04 verschoben werden kann.While the suction rolls 08; 09 continue to circulate and thereby the bow 14 in Further conveying direction, the can to align a side edge of the sheet 14 whole first frame part 03 together with the alignment cylinder 06 and the feed table 16 can be adjusted axially in the direction of the axis of rotation of the alignment cylinder 06. To serves a drive motor 17 which via a clutch 18 in a fixed bearing 19th mounted ball screw 21 drives. In the side component wall of the first Frame part 03 is a threaded nut 22 attached to the ball screw 21st is engaged so that the entire first by driving the ball screw 21 Frame part 03 can be moved in the linear guides 04.

Zur Drehmomentübertragung von der Antriebswelle 07 auf die Saugwalzen 08; 09 sind zwei drehfest mit der Antriebswelle 07 verbundene Naben 37; 38 vorgesehen, die zur Forrnatverstellung verschiebbar auf der Antriebswelle 07 festgelegt werden können. Zur Umfangsverstellung der Vordermarken 13 können die Saugtrommeln 08; 09 auf den Naben 37; 38 verdreht werden, wobei zur Feineinstellung der Vordermarken 13 jeweils Feinjustiereinrichtungen 39 zwischen den Naben 37; 38 einerseits und den Saugwalzen 08; 09 andererseits vorgesehen sind.For torque transmission from the drive shaft 07 to the suction rolls 08; 09 are two hubs 37 non-rotatably connected to the drive shaft 07; 38 provided for Format adjustment can be slidably set on the drive shaft 07. to Circumferential adjustment of the front brands 13, the suction drums 08; 09 on the Hubs 37; 38 are rotated, 13 for fine adjustment of the front marks Fine adjustment devices 39 between the hubs 37; 38 on the one hand and the suction rolls 08; 09 are provided on the other hand.

In Fig. 2 ist die Vorrichtung 01 mit den Antriebsmotoren 11; 17, der Saugwalze 08 und der daran angeordneten Vordermarke 13, dem aus drei Platten 23; 24; 26 gebildeten Anlegetisch 16, den Linearführungen 04 und dem ersten Rahmenteil 03 schematisch in seitlicher Ansicht dargestellt. Zur Messung des Kantenversatzes der in der Vorrichtung 01 auszurichtenden Bogen 14 sind insgesamt vier Sensoren 27; 28; 29; 31 vorgesehen. Mit dem Sensor 27 kann der Kantenversatz, insbesondere der Kantenversatz der Vorderkante, eines Bogens 14 vor dem Einlaufen in die Vorrichtung 01 gemessen werden. Zur Vorausrichtung der Bogen 14 vor der eigentlichen Ausrichtung in der Vorrichtung 01 ist ein von zwei parallel zueinander verlaufenden Transportbändern gebildetes Stellorgan 32 der Vorrichtung 01 vorgelagert. In Abhängigkeit des Messergebnisses des Sensors 27 können die in Fig. 2 hintereinander liegend dargestellten Transportbänder 33; 34 mit unterschiedlichen Geschwindigkeiten angetrieben werden, so dass durch die Differenzgeschwindigkeit eine Ausrichtbewegung der Bogen 14 um eine Vertikalachse erzeugt wird. Ob mit dem Stellorgan 32 eine Vorderkante oder eine Seitenkante der Bogen 14 vorausgerichtet wird, ist grundsätzlich beliebig und eine Frage des jeweiligen Anwendungsfalls. In den meisten Fällen wird jedoch eine Vorderkante der Bogen 14 mit dem Stellorgan 32 vorausgerichtet werden.2 shows the device 01 with the drive motors 11; 17, the suction roller 08 and the front mark 13 arranged thereon, consisting of three plates 23; 24; 26 educated Feed table 16, the linear guides 04 and the first frame part 03 schematically in shown from the side. To measure the edge offset of the device 01 to be aligned sheet 14 are a total of four sensors 27; 28; 29; 31 provided. With the edge offset, in particular the edge offset of the sensor 27 Front edge of a sheet 14 measured before entering the device 01 become. To pre-align the sheet 14 before the actual alignment in the Device 01 is one of two conveyor belts running parallel to one another formed actuator 32 upstream of the device 01. Depending on the The measurement result of the sensor 27 can lie one behind the other in FIG. 2 shown conveyor belts 33; 34 with different speeds are driven so that an alignment movement by the differential speed the arc 14 is generated about a vertical axis. Whether with the actuator 32 one Front edge or a side edge of the sheet 14 is pre-aligned is fundamental arbitrary and a question of the respective application. In most cases however, a leading edge of the sheet 14 may be pre-aligned with the actuator 32.

Nach der Vorausrichtung durch das Stellorgan 32 werden die Bogen 14 in die Vorrichtung 01 eingefördert und kommen mit der Vorderkante an den zumindest geringfügig langsamer umlaufenden Vordermarken 13 zur Anlage. Durch die Relativgeschwindigkeit zwischen Bogen 14 und Vordermarken 13 läuft die Vorderkante auf die Vordermarken 13 auf und wird dabei ausgerichtet. Sobald die Vordermarken 13 ihren höchsten Punkt während eines Umlaufs passiert haben, ist die Ausrichtung der Vorderkante eines Bogens 14 im wesentlichen abgeschlossen und wird durch Messung mittels des Sensors 29 kontrolliert.After pre-alignment by the actuator 32, the sheets 14 are in the device 01 promoted and come with the leading edge at least slightly slower revolving front brands 13 to the system. By the relative speed between sheet 14 and front marks 13, the leading edge runs onto the front marks 13 and is aligned. As soon as the front marks 13 reach their highest point have happened during a round is the alignment of the leading edge of an arc 14 is essentially completed and is measured by means of the sensor 29 controlled.

Durch weiteren Antrieb der Saugwalzen 08; 09 wird der Bogen 14 in der Vorrichtung 01 weitergefördert und der Kantenversatz einer Seitenkante des Bogens 14 nach der Ausrichtung der Vorderkante an den Vordermarken 13 mittels des Sensors 28 vermessen. In Abhängigkeit des Messergebnisses des Sensors 28 wird das erste Rahmenteil 03 durch Antrieb des Antriebsmotors 17 so lange linear verstellt, bis die Differenz zwischen der Sollausrichtung der Seitenkante und der gemessenen Istausrichtung zu Null geworden ist. Auch während der Ausrichtung der Seitenkante des Bogens 14 wird der Bogen 14 durch fortlaufenden Antrieb der Saugwalzen 08; 09 in Förderrichtung weitergefördert. Dabei werden die Saugwalzen 08; 09 durch den Antriebsmotor 11 derart beschleunigt, dass der Bogen 14 bei Erreichen einer der Vorrichtung 01 nachgelagerten Vorrichtungen 36, beispielsweise eines Transferzylinders 36 , die gleiche Fördergeschwindigkeit aufweist wie die nachgelagerte Vorrichtung 36. Bei der Übergabe der Bogen 14 von der Vorrichtung 01 an die nachgelagerte Vorrichtung 36 wird die Ausrichtung der Vorderkante der Bogen 14 nochmals mittels des Sensors 31 vermessen, um die Einhaltung der vorgegebenen Lagetoleranzen zu kontrollieren.By further driving the suction rollers 08; 09, the bow 14 in the device 01 promoted and the edge offset of a side edge of the sheet 14 after the Measure the alignment of the front edge on the front marks 13 by means of the sensor 28. The first frame part 03 becomes dependent on the measurement result of the sensor 28 linearly adjusted by driving the drive motor 17 until the difference between the target orientation of the side edge and the measured actual orientation to zero has become. Also during the alignment of the side edge of the sheet 14 Sheet 14 by continuously driving the suction rolls 08; 09 in the conveying direction further promoted. The suction rollers 08; 09 by the drive motor 11 such accelerates that the sheet 14 is reached after reaching one of the device 01 Devices 36, for example a transfer cylinder 36, the same Has conveying speed like the downstream device 36. During the transfer the sheet 14 from the device 01 to the downstream device 36 becomes the Measure the alignment of the front edge of the sheets 14 again using the sensor 31, to check compliance with the specified position tolerances.

In Fig. 3 und 4 wird ein weiteres Ausführungsbeispiel einer Vorrichtung 41 dargestellt, deren Aufbau dem Aufbau der Vorrichtung 01 aus Fig. 1 mit zweitem Rahmenteil 02, erstem Rahmenteil 03, den Linearführungen 04, dem Anlegetisch 16 und der aus dem Antriebsmotor 17, der Kupplung 18, dem Festlager 19, der Gewindespindel 21 und der Gewindemutter 22 gebildeten Querverstelleinrichtung im wesentlichen entspricht.3 and 4 a further embodiment of a device 41 is shown, the structure of which is the structure of the device 01 from FIG. 1 with a second frame part 02, first frame part 03, the linear guides 04, the feed table 16 and the from Drive motor 17, the clutch 18, the fixed bearing 19, the threaded spindle 21 and the Threaded nut 22 formed transverse adjustment device corresponds substantially.

Der Ausrichtzylinder 06, Vorrichtung 41 weist zwei unabhängige Antriebsstränge auf, die die Bogen 14 unabhängig voneinander antreiben können. Anders als bei der Vorrichtung 01 wird bei der Vorrichtung 41 der Ausrichtzylinder 06 nicht von einer Antriebswelle 07, sondern von zwei Antriebswellen 42; 43 angetrieben, so dass die Umfangsgeschwindigkeit von Elementen 44; 46, z. B. von Zylinderelementen 44; 46, insbesondere von Saugwalzen 44; 46 durch entsprechende Ansteuerung von zwei Antriebsmotoren 47; 48 unabhängig voneinander eingestellt werden kann.The alignment cylinder 06, device 41 has two independent drive trains that can drive the bow 14 independently of each other. Different from the device 01 in the device 41 the alignment cylinder 06 is not driven by a drive shaft 07, but of two drive shafts 42; 43 driven so the Peripheral speed of elements 44; 46, e.g. B. of cylinder elements 44; 46 especially of suction rollers 44; 46 by appropriate control of two Drive motors 47; 48 can be set independently.

Zur normalen Förderung der Bogen 14 in Förderrichtung werden die Antriebsmotoren 47; 48 synchron zueinander angesteuert, so dass die Zylinderelemente 44; 46 mit gleicher Umfangsgeschwindigkeit umlaufen. Zur Ausrichtung einer Kante des Bogens 14, insbesondere zur Ausrichtung der Vorderkante, sind an den Zylinderelementen 44; 46 nicht wie bei der Vorrichtung 01 Vordermarken vorgesehen. Vielmehr werden zur Ausrichtung des Bogens 14 die Antriebsmotoren 47; 48 so von der Steuerung angesteuert, dass die Zylinderelemente 44; 46 eine bestimmte Differenzgeschwindigkeit aufweisen, durch die der linearen Förderbewegung der Bogen 14 in Förderrichtung eine Drehbewegung um eine vertikale Hochachse überlagert wird. Durch die Drehbewegung um die vertikale Hochachse kann die entsprechende Kante des Bogens 14 ausgerichtet werden.For normal conveyance of the sheet 14 in the conveying direction, the drive motors 47; 48 controlled synchronously with each other, so that the cylinder elements 44; 46 with the same Circumferential speed. To align an edge of the sheet 14, in particular for the alignment of the front edge, are on the cylinder elements 44; 46 not as intended for the front 01 device. Rather become Alignment of the arc 14, the drive motors 47; 48 so from the controller controlled that the cylinder elements 44; 46 a certain differential speed have through which the linear conveying movement of the sheet 14 in the conveying direction Rotational movement about a vertical vertical axis is superimposed. By the rotating movement the corresponding edge of the arch 14 can be aligned about the vertical vertical axis become.

Um den bei der Ausrichtung der Seitenkante des Bogens 14 erforderlichen Längenausgleich zwischen den Antriebsmotoren 47; 48 einerseits und den Antriebswellen 42; 43 andererseits zu ermöglichen, werden wiederum entsprechend ausgebildete Kupplungen 12, die einen Längenausgleich ermöglichen, verwendet.To the required in the alignment of the side edge of the sheet 14 Length compensation between the drive motors 47; 48 on the one hand and the drive shafts 42; 43, on the other hand, are trained accordingly Couplings 12 that allow length compensation are used.

Fig. 4 zeigt die Vorrichtung 41 mit dem vorgelagerten Stellorgan 32 und der nachgelagerten Vorrichtung 36 in einer schematisch dargestellten Seitenansicht. Die Funktion der Sensoren 27; 28; 31 zur Ansteuerung des Stellorgans 32 bzw. der Querverstelleinrichtung bzw. zur Endkontrolle der Bogenausrichtung entspricht der Funktion der Vorrichtung 01 (siehe Fig. 2). Anders als bei der Vorrichtung 01 sind bei der Vorrichtung 41 oberhalb der Zylinderelemente 44; 46 zwei Sensoren 49; 51 in Förderrichtung der Bogen 14 hintereinander angeordnet. Mit dem Sensor 49 wird der Kantenversatz der Vorderkante eines Bogens 14 unmittelbar vor der Übergabe des Bogens 14 an die Zylinderelemente 44; 46 gemessen und anschließend die Relativgeschwindigkeit zwischen den Zylinderelemente 44; 46 in Abhängigkeit des Messergebnisses des Sensors 49 so gewählt, dass die gewünschte Sollausrichtung der Vorderkante erreicht wird. Mit dem Sensor 51 wird die Ausrichtung der Vorderkante des Bogens 14 nach der ersten Ausrichtbewegung durch entsprechende Relativgeschwindigkeit zwischen den Zylinderelementen 44; 46 kontrolliert, wobei die Bogen 14 zum Zeitpunkt der Kontrolle durch den Sensor 51 noch immer an den Zylinderelementen 44; 46 anliegen. Ergibt sich bei der Messung durch den Sensor 51 eine nicht tolerierbare Abweichung der Ausrichtung der Vorderkante, werden die Zylinderelemente 44; 46 wiederum mit entsprechenden Relativgeschwindigkeiten angetrieben, um die Ausrichtung der Vorderkante zu korrigieren.Fig. 4 shows the device 41 with the upstream actuator 32 and downstream device 36 in a schematically illustrated side view. The Function of sensors 27; 28; 31 to control the actuator 32 or The transverse adjustment device or for the final inspection of the sheet alignment corresponds to the Function of the device 01 (see Fig. 2). Unlike the device 01 are in the Device 41 above the cylinder elements 44; 46 two sensors 49; 51 in Delivery direction of the sheet 14 arranged one behind the other. With the sensor 49 Edge offset of the leading edge of a sheet 14 immediately before the transfer of the Arc 14 to the cylinder elements 44; 46 measured and then the Relative speed between the cylinder elements 44; 46 depending on the Measurement result of the sensor 49 selected so that the desired target orientation of the Leading edge is reached. With the sensor 51, the orientation of the front edge of the Bow 14 after the first alignment movement by appropriate Relative speed between the cylinder elements 44; 46 controls, the Sheet 14 at the time of control by the sensor 51 still to the Cylinder elements 44; 46 concerns. Results from the measurement by sensor 51 an intolerable deviation in the orientation of the leading edge, the Cylinder elements 44; 46 again with corresponding relative speeds driven to correct the alignment of the leading edge.

Erst nach Korrektur der Ausrichtung der Vorderkante wird die Ausrichtung der Seitenkanten mittels des Sensors 28 gemessen und durch Antrieb des Motors 17 ausgerichtet. Only after correcting the alignment of the leading edge will the alignment of the Side edges measured by sensor 28 and by driving motor 17 aligned.
