Abstract
Einrichtung zum Steuern einer Bogenzufuhr zu einer Maschine, mit einer Detektoranordnung zum Bestimmen der Lage einer Kante eines Bogens relativ zu einem zeitweise beweglichen Anschlag und wobei mindestens ein Teil (21, 22) der Detektoranordnung (20-23) synchron mit dem Anschlag (7, 15) beweglich ist, dadurch gekennzeichnet, dass der Empfänger (23) eine Vielzahl einzelner Empfangselemente (24) aufweist, die matrixförmig in Zeilen und Spalten angeordnet sind, wobei die Spalten in Richtung der Zufuhr des Bogens (5) gegen den Anschlag (7, 15) liegen.Device for controlling a sheet feed to a machine, comprising a detector arrangement for determining the position of an edge of a sheet relative to a temporarily movable stop, and at least a part (21, 22) of the detector arrangement (20-23) being in synchronism with the stop (7, 15) is movable, characterized in that the receiver (23) has a plurality of individual receiving elements (24) which are arranged in a matrix in rows and columns, wherein the columns in the direction of supply of the sheet (5) against the stop (7, 15) lie.
Description
Die Erfindung betrifft eine Einrichtung zum Steuern einer Bogenzufuhr zu einer Maschine nach dem Oberbegriff des Patentanspruchs 1 oder nach dem Oberbegriff des Patentanspruchs 2.The invention relates to a device for controlling a sheet feed to a machine according to the preamble of
Beim Fördern zu einer Druckmaschine werden Bogen einzeln an Anschlägen ausgerichtet, bevor sie einem ersten Druckwerk zugeführt werden. Die Anschläge sind einstellbar. Die Lage eines Bogens an den Anschlägen gibt die Lage eines Druckbildes auf dem Bogen vor. Um eine hohe Registergenauigkeit zu erzielen, wird die Lage eines Bogens an Vorder- und Seitenmarken mittels Detektoranordnungen überwacht. Bestehen zwischen einer Ist- und einer Solllage eines Bogens Abweichungen, werden Stellelemente betätigt, die die Abweichungen kompensieren. Die Stellelemente wirken auf die Vorder- und Seitenmarken und/oder auf die Fördervorrichtung der Bogen von einem Stapel gegen die Vorder- und Seitenmarken.When fed to a printing press, sheets are individually aligned with stops before being fed to a first printing unit. The stops are adjustable. The position of a sheet at the stops indicates the position of a printed image on the sheet. To achieve high register accuracy, the location of a signature on front and side marks is monitored by detector arrays. If there are deviations between an actual position and a desired position of a sheet, adjusting elements are actuated which compensate for the deviations. The actuators act on the front and side marks and / or on the conveyor of the sheet from a stack against the front and side marks.

Die Offenlegungsschrift
Die Lösungen nach dem Stand der Technik sind nicht einsetzbar, wenn während des Ausrichtens eines Bogens an Vorder- und Seitenmarken ein vorhergehender Bogen über die Marken hinweg zu einer Maschine gefördert wird und den Strahlengang einer Detektoranordnung verdecken würde.The prior art solutions can not be used if, during the registration of a signature on the front and side marks, a preceding sheet is conveyed across the marks to a machine and obscures the beam path of a detector assembly.
Aufgabe der Erfindung ist es, eine Einrichtung zum Steuern einer Bogenzufuhr zu einer Maschine zu entwickeln, die ein Ausrichten eines Bogens an Anschlägen mit hoher Genauigkeit und über einen langen Zeitraum ermöglicht.The object of the invention is to develop a device for controlling a sheet feed to a machine, which allows an alignment of a sheet of attacks with high accuracy and over a long period.
Die Aufgabe wird mit einer Einrichtung gelöst, welche die Merkmale nach Patentanspruch 1 oder 2 aufweist. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The object is achieved with a device having the features of
Gemäß der Erfindung enthält eine Einrichtung zum Steuern der Bogenzufuhr eine Detektoranordnung, wobei ein Teil der Detektoranordnung mit einem Anschlag beweglich ist, an dem ein Bogen ausgerichtet werden soll.According to the invention, means for controlling the sheet feed includes a detector assembly, wherein a portion of the detector assembly is movable with a stop against which a sheet is to be aligned.
Bei einer Druckmaschine mit überlappter Zufuhr von Bogen ist ein Teil der Detektoranordnung an Vorderkantenanschlägen angeordnet, die unter eine Führungsebene eines Anlegertisches versenkbar sind. Es ist vorteilhaft, wenn eine optische Detektoranordnung einen Sender und einen Empfänger enthält, die gestellfest angeordnet sind, und ein strahlumlenkendes Bauelement enthält, welches mit einem Bogenanschlag beweglich ist. Als strahlumlenkende Elemente sind insbesondere Spiegel geeignet, deren Spiegelebenen senkrecht zueinander stehen. Es ist weiterhin möglich, einen Sender oder Empfänger gestellfest anzuordnen und dem zugeordneten Empfänger oder Sender mit den Anschlägen bewegt vorzusehen. Die Empfänger können zeilenförmige oder matrixförmige separate Empfangselemente aufweisen.In a sheet-fed sheet fed printing machine, a portion of the detector assembly is disposed on leading edge stops which are retractable below a guide plane of a feeder table. It is advantageous if an optical detector arrangement includes a transmitter and a receiver, which are arranged fixed to the frame, and contains a beam deflecting component which is movable with a sheet stop. As beam-deflecting elements in particular mirrors are suitable whose mirror planes are perpendicular to each other. It is also possible to arrange a transmitter or receiver frame-fixed and provide the associated receiver or transmitter moved with the stops. The receivers may have line-shaped or matrix-shaped separate receiving elements.
Die Erfindung soll nachstehend anhand eines Ausführungsbeispiels erläutert werden.The invention will be explained below with reference to an embodiment.
