Description

Die Erfindung betrifft eine Vorrichtung zur Steuerung einer die Lage einer Seitenkante eines auf einem Anlegtisch an Vordermarken nach der Vorderkante ausgerichteten Bogens erfassenden Messeinrichtung.The invention relates to a device for controlling a measuring device that detects the position of a side edge of a sheet aligned on a feed table on leading marks after the leading edge.

Aus der EP 0 753 407 B1 ist es bekannt, einen an Anlegmarken nach der Vorderkante ausgerichteten, auf dem Anlegtisch liegenden Bogen hinsichtlich der Lager seiner Seitenkante zu erfassen. Die Lage der Seitenkante wird mittels eines optoelektronischen Sensors mit integrierter Beleuchtung erfasst, indem ein Istsignal generiert wird, das mit einem in einer Steuereinrichtung abgelegten Sollsignal verglichen wird. Stimmen diese Signale nicht überein, erfolgt die Generierung eines Stellsignals, durch welches ein Stellelement angesteuert und damit das Greifersystem der Schwinganlage oder eines Zuführzylinders in axialer Richtung verschoben wird. Der optoelektronische Sensor ist in einem Abstand über dem Anlegtisch an einer Traverse mittels einer verschiebbaren Halterung angeordnet.From EP 0 753 407 B1 it is known to detect a sheet aligned with feed marks after the leading edge and lying on the feed sheet with respect to the bearings of its side edge. The position of the side edge is detected by means of an optoelectronic sensor with integrated illumination by generating an actual signal which is compared with a desired signal stored in a control device. If these signals do not match, the generation of a control signal, by which an actuating element is driven and thus the gripper system of the oscillating system or a feed cylinder is moved in the axial direction. The optoelectronic sensor is arranged at a distance above the feed table on a traverse by means of a displaceable holder.

Nachteilig ist, dass die optoelektronische Abtasteinrichtung manuell sowohl auf das Format des zur Verarbeitung gelangenden Bogenmaterials eingestellt, als auch der zu erfassenden Seitenkante zugeordnet werden muss. Außerdem ist es nachteilig, dass eine Speicherung eingestellter Positionen der Messeinrichtung für Wiederholaufträge nicht möglich ist.The disadvantage is that the opto-electronic scanning device manually adjusted both to the format of the reaching for processing sheet material, as well as the side edge to be detected must be assigned. Moreover, it is disadvantageous that storage of set positions of the measuring device for repeat orders is not possible.

Nach der DE 30 22 950 A1 ist es weiterhin bekannt, zwecks Regelung des Bandlaufs eines bandförmigen Gutes mit Hilfe einer Videokamera fortlaufend die Bahnkante zu erfassen und bei Abweichungen einen Stellbefehl zu realisieren, durch den die Bahnlage gesteuert wird.According to DE 30 22 950 A1, it is also known, for the purpose of controlling the tape running of a strip-shaped material with the aid of a video camera to continuously detect the web edge and to realize a control command in case of deviations, by which the web position is controlled.

Aufgabe der Erfindung ist es, die bekannte Vorrichtung so weiterzubilden, dass eine Positionierung bzw. Zuordnung der Messeinrichtung zu der zu erfassenden Seitenkante bei einem Formatwechsel ohne manuellen Eingriff sowie die Speicherung einer realisierten Position möglich ist.The object of the invention is to develop the known device so that a positioning or assignment of the measuring device to the side edge to be detected in a format change without manual intervention and the storage of a realized position is possible.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Durch die erfindungsgemäße Lösung ist es möglich, die Messeinrichtung zum Erfassen der Lage der Seitenkante eines zur Verarbeitung gelangenden Bogens bedarfsgerecht zu positionieren.According to the invention the object is achieved by the features of claim 1. By the solution according to the invention, it is possible to position the measuring device for detecting the position of the side edge of a reaching for processing sheet as needed.

In den Figuren 1 und 2 ist ein Anlegtisch 1 mit Vordermarken 5 dargestellt. Auf dem Anlegtisch 1 liegt ein Bogen 2, der mit seiner Vorderkante durch einen nicht dargestellten Bändertisch in Bogenförderrichtung 4 auf dem Anlegtisch 1 sowie gegen die Vordermarken transportiert und so bezüglich der Vorderkante ausgerichtet wurde. Der Anlegtisch 1 ist spiegelbildlich zu einer Maschinenmitte 3 ausgebildet, wobei die in Bogenförderrichtung 4 links liegende Seite als Seite I und die rechts liegende Seite als Seite II bezeichnet wird.. Die zur Verarbeitung gelangenden Bogen 2 werden in der Regel ebenfalls spiegelbildlich zur Maschinenmitte 4 zugeführt. Quer zur Bogenförderrichtung 4 ist im den Vordermarken 5 vorgeordneten Bereich über die Breite des Anlegtisches 1 gestellfest eine Traverse 6 vorgesehen. An der Traverse 6 ist eine Messeinrichtung 7, die als Videokamera 8 ausgebildet ist, mittels eines Halters 9 angeordnet. Der Halter 9 ist spielfrei und durch nicht gezeigte Stellmittel entlang der Traverse 6 verschiebbar gelagert. Dem Halter 9 ist eine Wegmesseinrichtung 10 zugeordnet. Die Wegmesseinrichtung 10 weist einen Messwertaufnehmer 11 auf, der dem Halter 9 zugeordnet ist. Mit der Traverse 6 ist ein Messwertgeber 12 verbunden. Der Messwertgeber 12 kann z.B. als gespurtes Magnetband, als Lineal oder als Potentiometer und entsprechend der Messwertaufnehmer 11 als Lesekopf oder als Schleifer ausgebildet sein. Der Messwertgeber 12 weist einen Nullpunkt auf und ist so der Traverse 6 zugeordnet, dass der Nullpunkt mit der Maschinenmitte 3 übereinstimmt.
Aus dieser Nullposition heraus kann der Halter 9 und damit die Messeinrichtung 7 bzw. die Videokamera 8 durch die nicht dargestellten Stellmittel nach der linken Seite I, wie in Figur 1 dargestellt, oder nach der rechten Seite II verfahren werden, wobei die durch die Wegmesseinrichtung 10 generierten Messwerte einer Rechnereinheit zugeführt werden, so dass ständig über eine Auswerteinheit die Position des Halters 9 und damit der Videokamera 8 ermittelbar ist. Bei einem Auflagewechsel wird in eine Eingabeeinheit das neue Format und Seite I oder Seite II eingegeben in Abhängigkeit davon, ob die linke Seitenkante 2.1 oder die rechte Seitenkante 2.2 des Bogens 2 erfasst werden soll.In Figures 1 and 2, a feed table 1 is shown with front marks 5. On the feed table 1 is a sheet 2, which was transported with its front edge by a belt table, not shown in the sheet conveying direction 4 on the feed table 1 and against the front marks and was aligned with respect to the leading edge. The feed table 1 is mirror-inverted to a machine center 3, wherein the left in sheet conveying direction 4 side as side I and the right side is referred to as side II .. The reaching for processing sheet 2 are also also mirror image fed to the machine center 4 , Transverse to the sheet conveying direction 4 in the front marks 5 upstream region over the width of the feed table 1 frame fixed a cross member 6 is provided. On the traverse 6 is a measuring device 7, which is designed as a video camera 8, arranged by means of a holder 9. The holder 9 is free of play and slidably mounted by means not shown adjusting means along the traverse 6. The holder 9 is associated with a displacement measuring device 10. The displacement measuring device 10 has a transducer 11, which is assigned to the holder 9. With the Traverse 6 a transmitter 12 is connected. The transmitter 12 may be formed, for example, as a spun magnetic tape, as a ruler or as a potentiometer and corresponding to the transducer 11 as a read head or as a grinder. The transducer 12 has a zero point and is assigned to the traverse 6, that the zero point coincides with the machine center 3.
From this zero position, the holder 9 and thus the measuring device 7 or the video camera 8 can be moved by the adjusting means, not shown, to the left side I, as shown in Figure 1, or to the right side II, wherein by the displacement measuring device 10th generated measured values are supplied to a computer unit, so that the position of the holder 9 and thus of the video camera 8 can be determined constantly via an evaluation unit. In the case of a circulation change, the new format and page I or page II are entered into an input unit as a function of whether the left side edge 2.1 or the right side edge 2.2 of the sheet 2 is to be detected.

Damit wird die Messeinrichtung 7 bzw. die Videokamera 8 in eine Position verschoben, in der, wie in Figur 1 dargestellt, in einem Toleranzbereich um einen für das entsprechende Format vorgegebenen Sollwert die Istlage der linken Seitenkante 2.1 erfasst wird. Bei Verwendung der Videokamera 8 wird der an den Vordermarken 5 anliegende Bogen 2 zur Fremdlichtkompensation angeblitzt und die Seitenkante 2.1 von der Videokamera 8 als Kontrastsprung erfasst. Das von der Videokamera 8 erzeugte Signal wird dem Rechner zugeführt und zur messtechnischen Auswertung verwendet. Dabei wird das Istsignal mit einem Sollsignal verglichen und bei Abweichungen vom Sollsignal ein Stellsignal generiert, das einem vor- oder nachgeordnetem System zugeführt wird zur Realisierung einer Stellhandlung.
Ist es erforderlich, nach einem Maschinendurchlauf die Bogen 2 nochmals, um z.B. nach einem Schöndruck einen Widerdruck zu realisieren, durchlaufen zu lassen, müssen diese gewendet werden, so dass die Seitenkante 2.1 auf der Seite II detektiert werden muss. Die Videokamera 8 kann, da der Abstand zwischen der Maschinenmitte 3 und der Position zum Erfassen der Lage der Seitenkante 2.1 auf der Seite I im Rechner erfasst ist, im gleichen Abstand zur Maschinenmitte 3 auf der Seite II positioniert werden, so dass problemlos eine Weiterverarbeitung der "gestülpten" Bogen 2 möglich ist. Macht es sich aus technologischen Gründen erforderlich, beim Widerdruck die Seitenkante 2.1 auf der Seite II in einem andren Abstand zur Maschinenmitte 3 als beim Schöndruck zu positionieren, ist das Positionieren der Videokamera 8 problemlos möglich durch Eingabe von Korrekturfaktoren, wodurch die Videokamera 8 entsprechend näher oder weiter entfernt zur Maschinenmitte 3 positioniert wird.Thus, the measuring device 7 or the video camera 8 is moved to a position in which, as shown in Figure 1, the actual position of the left side edge 2.1 is detected in a tolerance range to a predetermined value for the appropriate format. When using the video camera 8, the voltage applied to the front marks 5 sheet 2 is flashed for extraneous light compensation and detects the side edge 2.1 of the video camera 8 as a contrast jump. The signal generated by the video camera 8 is supplied to the computer and used for metrological evaluation. In this case, the actual signal is compared with a desired signal and, in the event of deviations from the desired signal, an actuating signal is generated which is fed to a preceding or following system for realizing a parking action.
If it is necessary, after a machine run, the sheets 2 again, to realize, for example, after a Perfecting a perfecting to go through, they must be reversed, so that the side edge 2.1 must be detected on the side II. The video camera 8, since the distance between the machine center 3 and the position for detecting the position of the side edge 2.1 is detected on the side I in the computer, are positioned at the same distance from the machine center 3 on the side II, so that easily further processing of "inverted" bow 2 is possible. If it is necessary for technological reasons to position the side edge 2.1 on the side II at a different distance to the machine center 3 than the recto printing, the positioning of the video camera 8 is easily possible by input of correction factors, whereby the video camera 8 accordingly closer or further away to the machine center 3 is positioned.

Grundsätzlich ist es auch möglich, die Wegmesseinrichtung 10 den Stellelementen zuzuordnen, die zum Verschieben des Halters 9 auf der Traverse 6 vorgesehen sind.
Es ist weiterhin möglich, im Rechner Werte zu speichern, die den zur Verarbeitung gelangenden Formaten der Bogen 2 zugeordnet sind. Nach Eingeben des zur Verarbeitung vorgesehenen Formats sowie nach Vorgabe der Seite I, II des Anlegtisches 1, auf der die Seitenkante des Bogens 2 erfasst werden soll, wird die Messeinrichtung 10 positioniert.In principle, it is also possible to assign the displacement measuring device 10 to the actuating elements, which are provided for displacing the holder 9 on the traverse 6.
It is also possible to store values in the computer which are assigned to the formats of the sheets 2 for processing. After entering the intended format for processing and according to the specification of the side I, II of the feed table 1, on which the side edge of the sheet 2 is to be detected, the measuring device 10 is positioned.
