Description

Die Erfindung bezieht sich auf ein Auslagesystem für flächige Druckprodukte insbesondere an einem Bogenausleger von Rotationsdruckmaschinen.The invention relates to a delivery system for flat printed products, in particular on a sheet delivery of rotary printing machines.

DE 42 21 928 A1 offenbart eine Vorrichtung zum Non-Stop-Stapelwechsel im Ausleger. Ein Hilfsstapelträger ist in Förderrichtung der Bogen zwischen zwei Bogen einschiebbar, wobei auf einem Hilfsstapel die ankommenden Bogen vorübergehend aufgenommen werden. Zur Ablage des Hilfstapels auf einen neuen Hauptstapelträger nach dem Hauptstapelwechsel sind geeignete Mittel vorgesehen. Der Hilfsstapelträger weist eine geringe Schichtdicke auf und verbleibt unter dem Hilfsstapel, so daß er als Unterlage bei dessen Ablage auf dem ausgewählten Hauptstapelträger wirksam ist. Ein solcher Hilfsstapelträger kann entweder von einer Bahnrolle abgeschnitten oder einzeln aus einer Wechselkassette entnommen werden.DE 42 21 928 A1 discloses a device for non-stop stack changing in the delivery. An auxiliary stack carrier can be inserted between two sheets in the conveying direction of the sheets, the incoming sheets being temporarily picked up on an auxiliary stack. Suitable means are provided for storing the auxiliary stack on a new main stack carrier after the main stack change. The auxiliary stack carrier has a small layer thickness and remains under the auxiliary stack, so that it acts as a base when it is deposited on the selected main stack carrier. Such an auxiliary stack carrier can either be cut from a web roll or removed individually from an interchangeable cassette.

DE 44 05 586 C1 offenbart eine Vorrichtung zur exakten Trennung eines Hilfsstapels oder eines Hauptstapels bei einem Non-Stop-Ausleger in einer bogenverarbeitenden Druckmaschine. Dabei sind Träger und ein Querstapel mittels Koppelgliedern vertikal beweglich an einer an der Bogenbremse befestigten Traverse angelenkt. Am Träger sind untere Anschläge und Keile in Richtung Stapel angeordnet, auf der dem Stapel abgewandten Seite des Trägers ist parallel dazu eine von einem Arbeitszylinder betätigbare Koppelstange angeordnet, die über ternäre Glieder die hinteren Bogenhochhalter betätigt.DE 44 05 586 C1 discloses a device for the exact separation of an auxiliary stack or a main stack in a non-stop delivery in a sheet-fed printing press. Carrier and a cross stack are articulated vertically by means of coupling links on a crossbar attached to the sheet brake. Lower stops and wedges are arranged on the carrier in the direction of the stack, on the side of the carrier facing away from the stack there is arranged in parallel a coupling rod which can be actuated by a working cylinder and which actuates the rear arch support via ternary members.

Aus der Fachveröffentlichung "The Continuous Delivery System (CDS)" der Firma Michael Manufacturing, Inc., Little Fery, New Jersey 07643 aus dem Jahre 1995 ist eine Hilfsstapelunterlage bekanntgeworden, die in seitlichen Führungen läuft und nach dem Rolladenprinzip ein- und bei Bedarf ausgefahren werden kann, um eine Hilfsstapelunterlage zu bilden. Der aus miteinander zusammenhängenden Rollen bestehende Rolladen kann bei Bedarf über die Oberseite des Hauptstapels gestellt werden und bildet so eine Hilfsstapelunterlage, auf die die produzierten Bogen weiterhin ausgelegt werden können. Dabei senkt sich der in einer absenkbaren Lade aufgenommene Rolladen je nach Stapelwachstum ab, bis der Hauptstapel entsorgt und eine neue Stapelunterlage vorbereitet ist.From the specialist publication "The Continuous Delivery System (CDS)" by Michael Manufacturing, Inc., Little Fery, New Jersey 07643 from 1995, an auxiliary stacking pad has become known that runs in side guides and after the Roller shutter principle can be retracted and extended if necessary to form an auxiliary stacking pad. The roller shutter, which consists of interrelated rolls, can be placed over the top of the main stack if necessary and thus forms an auxiliary stacking base on which the sheets produced can still be laid out. Depending on the stack growth, the roller shutter, which is held in a lowerable drawer, lowers until the main stack is disposed of and a new stacking pad is prepared.

DE 42 17 816 C2 schließlich offenbart eine Einrichtung zur kontinuierlichen Auslage flächiger Druckprodukte, bei welcher ein der Stapeltrennung in Haupt- und Hilfsstapel dienendes Trennband vorgesehen ist. Dieses Trennband umfaßt eine verbreitert ausgeführte Trennkante, die quer zur Papierlaufrichtung in den Stapelbereich einfahrbar ist.Finally, DE 42 17 816 C2 discloses a device for the continuous delivery of flat printed products, in which a separating belt is provided which serves to separate the stacks into the main and auxiliary stacks. This separating belt comprises a widened separating edge which can be moved into the stacking area transversely to the paper running direction.

Aus DE 41 31 015 A1 ist ein Bogenausleger bekannt, bei dem eine Non-Stop-Einrichtung zwei im Bereich der Stapelseitenkanten vorgesehene, gegenläufig von einer seitlichen Warteposition in eine den Hauptstapel übergreifende Abdeckposition bewegbare Trennelemente umfaßt, die in der Trennstellung einen Einfahrspalt für den jeweils zugeordneten Hilfsstapelträger offenhalten und bei eingefahrenem Hilfsstapelträger zurückziehbar sind.From DE 41 31 015 A1 a sheet delivery is known, in which a non-stop device comprises two separating elements provided in the area of the stack side edges, which can be moved in opposite directions from a lateral waiting position into a covering position which overlaps the main stack and which in the separating position has an entry gap for each keep the assigned auxiliary stack carrier open and retractable when the auxiliary stack carrier is retracted.

Ausgehend vom skizzierten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, den Bogenausleger einer Rotationsdruckmaschine so zu verbessern, daß für alle in der Rotationsdruckmaschine verarbeitbaren Papiersorten bei Non-Stop und bei Hürdenbetrieb die kantensaubere Stapelbildung nicht beeinträchtigt wird.Starting from the outlined state of the art, the invention has for its object to improve the sheet delivery of a rotary printing press so that for all paper types that can be processed in the rotary printing press the non-stop stack formation is not impaired in the case of non-stop and hurdle operation.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst.This object is solved by the features of claim 1.

Die damit erzielbaren Vorteile sind vielfältiger Natur. Der Hilfsstapelrahmen umfaßt das verfahrbare Hilfsstapelaufnahmeelement und bildet ein steifes Aufnahmesystem in welchem ein Hilfsstapel zuverlässig verfahrbar ist. Die Integration des verfahrbaren Hilfsstapelaufnahmeelementes in den Hilfsstapelrahmen erlaubt ein einfaches Auswechseln des Hilfsstapelträgers mit wenigen Handgriffen. Da zudem die Bewegung des Hilfsstapelaufnahmeelementes samt Hilfsstapelträger beim Stapeltrennvorgang in Papierlaufrichtung erfolgt, wird die kantensaubere Stapelbildung nicht beeinträchtigt.The advantages that can be achieved are diverse. The auxiliary stack frame comprises the movable auxiliary stack receiving element and forms a rigid receiving system in which an auxiliary stack can be moved reliably. The integration of the movable Auxiliary stack receiving element in the auxiliary stack frame allows easy replacement of the auxiliary stack carrier in a few simple steps. Since, in addition, the movement of the auxiliary stack receiving element including the auxiliary stack carrier takes place in the paper running direction during the stack separation process, the edge-clean stack formation is not impaired.

Am verfahrbaren Hilfsstapelaufnahmeelement, welches in Papierlaufrichtung verfahrbar ist, kann in einer Quertraverse entweder ein Rechen- oder ein Schwebetisch befestigt werden. Der Luftanschluß an den Schwebetisch erfolgt über ein in der Quertraverse des verfahrbaren Hilfsstapelaufnahmeelementes vorgesehene Luftzuführung. Eine am Vorderteil des Hilfsstapelrahmens vorgesehene Traverse ist mit Haltefingern versehen; diese Haltefinder sind federvorgespannt und können, um Verletzungen des Druckers vorzubeugen, auch abgeschwenkt werden. Bei Verwendung eines Rechens, der mit seinem hinteren Bereich auf der Quertraverse des verfahrbaren Hilfsstapelaufnahmeelementes montiert ist, können die vorderen Enden der Rechenzinken in den Hauptstapelbereich eingefahrener Position von den Haltefingern abgestützt werden.On the movable auxiliary stack receiving element, which can be moved in the direction of paper travel, either a rake or a floating table can be attached in a crossbar. The air connection to the hover table is made via an air supply provided in the crossbar of the movable auxiliary stack receiving element. A cross member provided on the front part of the auxiliary stack frame is provided with holding fingers; these stop finders are spring-loaded and can also be swung down to prevent injury to the printer. When using a rake, which is mounted with its rear area on the crossbar of the movable auxiliary stack receiving element, the front ends of the rake tines can be supported by the holding fingers in the position in which the main stack area is retracted.

In weiterer Ausgestaltung des der Erfindung zugrundeliegenden Gedankens ist in das Hilfsstapelaufnahmeelement eine Hilfsstapelunterlage einsetzbar, sei es ein Schwebetisch oder Rechen mit mehreren sich über die Stapelbreite nebeneinander angeordneten Rechenzinken. Zur Anbindung des Schwebetisches an die Luftversorgung ist die Quertraverse des Hilfsstapelaufnahmeelementes mit einer Niederdruckluftzuführung versehen.In a further embodiment of the idea on which the invention is based, an auxiliary stack support can be inserted into the auxiliary stack receiving element, be it a floating table or rake with a plurality of rake tines arranged side by side over the stack width. To connect the floating table to the air supply, the crossbar of the auxiliary stack receiving element is provided with a low-pressure air supply.

Der Hilfsstapelrahmen ist an seiner vorderen Traverse mit Haltefingern versehen, die schwenkbar ausgebildet sind. Die Haltefinger stützen das vordere Ende von Rechenzinken, falls im Hilfsstapelaufnahmeelement ein Rechen montiert ist, ab. Auf diese Weise wird eine gleichmäßige Abstützung der in den Hauptstapelbereich eingefahrenen Hilfsstapelunterlage erreicht, die jeweils im Hilfsstapelaufnahmeelement vorgesehen ist. Darüberhinaus kann im Hilfsstapelaufnahmeelement ein Sendeelement einer Lichtschranke vorgesehen sein, wie auch der Empfänger entweder am Hilfsstapelaufnahmeelement oder am Hilfsstapelrahmen vorgesehen werden kann. Zur Endlagendämpfung sind am Hilfsstapelrahmen Stoßdämpfer vorgesehen, die ein Abfedern der Verfahrbewegung des Hilfsstapelaufnahmeelementes bewirken.The auxiliary stack frame is provided on its front crossmember with holding fingers which are designed to be pivotable. The holding fingers support the front end of rake tines if a rake is mounted in the auxiliary stack receiving element. In this way, a uniform support of the auxiliary stack support that has been moved into the main stack area is achieved, which is provided in each case in the auxiliary stack receiving element. In addition, a transmission element of a light barrier can be provided in the auxiliary stack receiving element, as can the receiver either on the auxiliary stack receiving element or on the auxiliary stack frame can be provided. Shock absorbers are provided on the auxiliary stack frame for cushioning the end position, which cushion the travel movement of the auxiliary stack receiving element.

Der Hilfsstapelrahmen besteht aus Hohlprofilen, die Stelleinheiten wie z.B. kolbenstangenlose Pneumatikzylinder aufnehmen. Durch eine sich über den Bereich des Verfahrweges der Stelleinheiten erstreckende Längsöffnung in den Hohlprofilen des Hilfsstapelrahmens ragen Mitnehmer, die die Bewegung des Hilfsstapelaufnahmeelementes initiieren. Die Verfahrwege der Stelleinheiten in den Hohlprofilen können über Sensoren abgefragt werden. Dabei können induktiv arbeitende Sensoren oder ähnliche eingesetzt werden.The auxiliary stack frame consists of hollow profiles, the actuators such as Take up the rodless pneumatic cylinder. Carriers, which initiate the movement of the auxiliary stack receiving element, project through a longitudinal opening in the hollow profiles of the auxiliary stack frame which extend over the region of the travel path of the actuating units. The travel paths of the actuators in the hollow profiles can be queried using sensors. Inductive sensors or similar can be used.
