Description

Die vorliegende Erfindung betrifft einen papierführenden Zylinder gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a paper-guiding cylinder according to the preamble of claim 1.

Die US 5,484,379 beschreibt einen Falzapparat für Rollenrotationsdruckmaschinen. Ein derartiger Falzapparat umfasst ein Paar zusammenwirkender Sammel- und Messerzylinder, die eine Papierbahn in Bahnsegmente schneiden. Ein Bandleitsystem umschließt einen Abschnitt der Oberfläche des Sammelzylinders bis vor eine Einlaufstelle der Papierbahn zwischen dem Sammel- und dem Messerzylinder. Dieses Bandleitsystem verhindert ein Zurückfedern der frisch geschnittenen Vorderkante der Papierbahn von dem Band. Das Bandleitsystem ist dabei neben dem Sammelzylinder angeordnet und kontaktiert einen Vorderkantenabschnitt der Materialbahn, die sich auf der bevorzugten Oberfläche des Sammelzylinders befindet. Das Bandleitsystem liegt an der Vorderkante der Materialbahn in Transportrichtung der Papierbahn an. Daher üben der Sammelzylinder und das Bandleitsystem auf der Zylinderoberfläche eine Vorspannung der Vorderkante in die Transportrichtung der Papierbahn aus. Durch die Vorspannung der Vorderkante der Materialbahn auf der Zylinderoberfläche, muss die Vorderkante auf die Oberfläche des jeweiligen Zylinders rutschen. Je nach Papierart und der Anzahl der Bahnstränge der jeweiligen Materialbahn, hängt die Qualität der zu späteren Zeitpunkten vorzunehmen Falze von der Position ab, in der die frisch geschnittene Vorderkante der Materialbahn von den jeweiligen Greiferelementen ergriffen wird.US 5,484,379 describes a folder for web-fed rotary printing presses. On such folder comprises a pair of cooperating collecting and knife cylinders, that cut a paper web into web segments. A tape control system encloses you Section of the surface of the collecting cylinder up to an entry point of the paper web between the collecting and the knife cylinder. This tape guidance system prevents one Spring back the freshly cut leading edge of the paper web from the belt. The Belt guidance system is arranged next to the collecting cylinder and contacts one Leading edge portion of the web of material located on the preferred surface of the Collecting cylinder is located. The belt guidance system is located on the front edge of the material web in the direction of transport of the paper web. Therefore, the collecting cylinder and that practice Belt guidance system on the cylinder surface a bias of the leading edge in the Direction of transport of the paper web. By pre-tensioning the front edge of the Material web on the cylinder surface, the leading edge must be on the surface of the of the respective cylinder. Depending on the type of paper and the number of web strands respective material web, depends on the quality to be made at later times Fold from the position where the freshly cut leading edge of the web of the respective gripper elements is gripped.

Der Erfindung liegt die Aufgabe zu Grunde, ein sicheres Ergreifen der neuen Vorderkante der Materialbahn, von der die jeweiligen Produkte geschnitten werden, zu gewährleisten, ohne dass die Greiferelemente den Schneidevorgang behindern.The invention is based on the object of securely grasping the new leading edge the material web from which the respective products are cut, without the gripper elements hindering the cutting process.

Diese Aufgabe wird erfindungsgemäß durch einen papierführenden Zylinder mit den Merkmalen gemäß Anspruch 1 gelöst. This object is achieved by a paper-carrying cylinder with the Features solved according to claim 1.

Die Vorteile der vorliegenden Erfindung liegen darin, dass die Bahn keine Relativbewegung bezüglich des Zylinders ausführt. Daher wird ein ungenaues Ausrichten der Vorderkante einer mehrere Bahnstränge aufweisenden Materialbahn verhindert. Darüber hinaus wird ein Greiferelement in zwei Schritten bewegt, um eine Ausfahrbewegung nach dem Schneiden als ersten Schritt und eine Greifbewegung des oberen Abschnitts des Greiferelements von einer oben offenen, ausgefahrenen Position in Abwärtsrichtung als zweiten Schritt zu ermöglichen.The advantages of the present invention are that the web does not Performs relative movement with respect to the cylinder. Hence an inaccurate alignment the front edge of a material web having several web strands prevented. In addition, a gripper element is moved in two steps to one Extending movement after cutting as the first step and a gripping movement of the upper section of the gripper element from an open, extended position in Allow downward direction as a second step.

In einer Ausführungsform der Erfindung umfassen die Greiferelemente jeweils einen ersten und einen zweiten Abschnitt. Der zweite Abschnitt umfasst einen abgeschrägten hakenförmigen Abschnitt zum Greifen der Vorderkante einer Materialbahn. Die Vorderkante kann mehrere Schichten oder Bahnstränge aufweisen, die von dem Greiferelement sicher erfasst werden müssen, ohne dass die Vorderkante der Materialbahn, wenn sie auf der Oberfläche des papierführenden Zylinders angeordnet ist, bewegt wird. Die Produktgreiferelemente sind an der Peripherie des papierführenden Zylinders angeordnet und einem jeweiligen Gegenstück zu den Schneidelementen auf der Zylinderoberfläche für den Schneidevorgang zugeordnet. Um das Produktgreiferelement auf der Zylinderoberfläche zu bewegen, ist eine Vielzahl von Schaltelementen vorhanden, anhand derer eine Zwei-Schritt-Bewegung der Greiferelemente durchgeführt wird.In one embodiment of the invention, the gripper elements each comprise a first one and a second section. The second section includes a beveled hook-shaped section for gripping the front edge of a material web. The The leading edge can have multiple layers or web strands that differ from that Gripper element must be securely gripped without the front edge of the material web, when placed on the surface of the paper-guiding cylinder. The product gripper elements are on the periphery of the paper-carrying cylinder arranged and a respective counterpart to the cutting elements on the Mapped cylinder surface for the cutting process. To the product gripper element to move on the cylinder surface, there are a variety of switching elements, on the basis of which a two-step movement of the gripper elements is carried out.

Die Schaltelemente umfassen ein Nockenelement, das die Form einer zweispurigen Nockenbahn mit einer ersten und eine zweiten Spur aufweist. Die Spuren weisen erste und zweite Profile auf, die jeweils niedrige und hohe Positionsabschnitte umfassen. Die Profile der Spuren sind die jeweiligen Nockenbahnoberflächen, die mit den jeweiligen Schaltelementen, wie z.B. den Nockenfolgern der Greiferelemente, zusammenwirken.The switching elements include a cam element that is in the form of a two-track Has cam track with a first and a second track. The tracks show first and second profiles, each comprising low and high position sections. The profiles of the tracks are the respective cam track surfaces that match the respective Switching elements, e.g. the cam followers of the gripper elements.

Die Schaltelemente umfassen eine ortsfeste Schwenkachse, an der die Greiferelemente befestigt sind. Zwischen der ortsfesten Schwenkachse und dem Produktgreiferelement ist ein Bindeglied, z.B. ein Hebel oder ein ähnliches Element, angeordnet. Ein weiteres Schaltelement, das mit einer der Spuren der zweispurigen Nockenbahn zusammenwirkt, dreht sich anhand eines Bindeglieds um eine zweite Schwenkachse. Wenn das zweite Schaltelement sich anhand eines Bindeglieds dreht, dient diese Drehbewegung um seine zweite Schwenkachse zum Ausfahren des Greiferelements in eine ausgefahrene Position an der Zylinderoberfläche.The switching elements comprise a fixed pivot axis on which the gripper elements are attached. Is between the fixed pivot axis and the product gripper element a link, e.g. a lever or a similar element. Another one Switching element that interacts with one of the tracks of the two-track cam track, rotates around a second swivel axis using a link. If the second Switching element rotates on the basis of a link, this rotary movement serves around its second pivot axis for extending the gripper element into an extended position the cylinder surface.

Die zweite Schwenkachse wirkt mit einem ersten Nockenfolger zusammen, der seinerseits mit dem zuvor genannten ersten Nockenprofil zusammenwirkt. Indem der erste Nockenfolger dem ersten Nockenprofil folgt, wird er in eine ausgefahrene Position gebracht und bewegt dabei das Produktgreiferelement in eine ausgefahrene Position über dem jeweiligen Abschnitt des papierführenden Zylinders. Das Greiferelement, dem ein zweites Schaltelement, das der jeweiligen Nockenbahn auf der zweiten Spur folgt, und welches sich in ausgefahrener Position befindet, wird von seiner erhöhten Position um eine zweite Schwenkachse in eine abwärts gerichtete Bewegung gedreht, wobei es die Vorderkante der Materialbahn ergreift, ohne die Vorderkante der Materialbahn zu bewegen.The second pivot axis interacts with a first cam follower, which in turn interacts with the aforementioned first cam profile. By the first Cam follower follows the first cam profile, it is in an extended position brought and moves the product gripper element into an extended position the respective section of the paper-carrying cylinder. The gripper element, the one second switching element, which follows the respective cam track on the second track, and which is in the extended position is increased by one from its raised position second pivot axis rotated in a downward movement, being the Front edge of the material web grips without the front edge of the material web move.

Ein papierführender Zylinder, der ein dual-betriebenes Greiferelement gemäß der oben angeführten Beschreibung aufweist, wird vorzugsweise in einem Falzapparat für Anwendungen im Bereich des Akzidenz- und Zeitungsdrucks verwendet.A paper-carrying cylinder, which is a dual-operated gripper element according to the above Has given description, is preferably in a folder for Applications in the field of commercial and newspaper printing used.

Nach einem erfindungsgemäßen Verfahren zum Betätigen eines Produktgreiferelements wird ein Produktgreiferelement, das einer Oberfläche eines papierführenden Zylinders zugeordnet ist, in einem ersten Schaltschritt von einer zurückgezogenen Position in eine ausgefahrene Position über der Zylinderoberfläche gebracht und in einem zweiten Schaltschritt von einer ausgefahrenen Position in einer Abwärtsbewegung zu der Position der Vorderkante auf dem papierführenden Zylinder bewegt. Der Schritt der Ausfahrbewegung und der Schritt der Greifbewegung, der in einer Abwärtsbewegung erfolgt, erfolgen nacheinander, damit der Greifvorgang ohne Störung des Schneidevorgang erfolgen kann. In diesem ersten Schritt, der die Ausfahrbewegung des Produktgreiferelements beschreibt, wird der erste Abschnitt des Produktgreiferelements in eine ausgefahrene Position gebracht. Nach dem Schalten des zweiten Schaltelements, z.B. eines Nockenfolgers, wird das Produktgreiferelement, das sich in einer ausgefahrenen Position befindet, abwärts bewegt, um den aus mehreren Schichten bestehenden Bahnstrang der Materialbahn auf der Oberfläche des papierführenden Zylinders zu ergreifen. Die Abwärtsbewegung des ersten Abschnitts des Produktgreiferelements auf die Oberfläche des papierführenden Zylinders zu unterbindet jegliche Bewegung der Vorderkante, da diese geschnittene Vorderkante in ihrer Ausrichtung in der Nähe der Nut, wo die Gegenstücke der Schneidelemente, wie z.B. Nutleisten auf der Oberfläche des papierführenden Zylinders aufgenommen werden, ergriffen wird.According to a method according to the invention for actuating a product gripper element becomes a product gripper element, the surface of a paper-guiding cylinder is assigned in a first switching step from a retracted position into a extended position brought over the cylinder surface and in a second Switching step from an extended position in a downward movement to the position the leading edge moves on the paper-guiding cylinder. The step of Extending movement and the step of gripping movement, which in a downward movement takes place one after the other so that the gripping process without disrupting the cutting process can be done. In this first step, the extension movement of the Product gripper element describes, the first section of the product gripper element in brought an extended position. After switching the second switching element, e.g. a cam follower, the product gripper element, which is in an extended Position is located, moved down to the multilayer Web strand of the material web on the surface of the paper-guiding cylinder seize. The downward movement of the first section of the product gripper element onto the Surface of the paper-guiding cylinder prevents any movement of the Leading edge, since this cut leading edge is aligned near the groove, where the counterparts of the cutting elements, e.g. Groove strips on the surface of the paper-carrying cylinder are picked up, is taken.

Fig. 2 zeigt schematisch ein Produktgreiferelement, das sich zur Durchführung eines Schneidvorgangs in der zurückgezogenen Position befindet.Fig. 2 shows schematically a product gripper element, which is used to carry out a Cutting process is in the retracted position.

In der Ausgangsposition 37 wird ein dual-betriebenes Produktgreiferelement 24 in der zurückgezogenen Position gezeigt. Entlang einer Peripherie 18 eines ersten papierführenden Zylinders 8 ist eine Vielzahl von Produktgreiferelementen 24 angeordnet, die mit einer Anzahl von Schneidelementen 23 zusammenwirken. Die Produktgreiferelemente 24 umfassen jedes jeweils einen ersten Abschnitt 24.1 und einen zweiten, zum ersten Abschnitt gewinkelten Abschnitt 24.2. Eine Schaltbahn 31, die hier als zweispurige Bahn mit den zwei Nockenlaufbahnen 34, 35 dargestellt ist, ist einem ersten papierführenden Zylinder 8 zugeordnet. Die Schaltbahn kann aber auch zwei unabhängig von einander einstellbare Laufbahnen, die die entsprechenden Bahnen 34, 35 aufweisen, umfassen. Durch zwei unabhängige Bahnen 34, 35 kann ein unabhängiges Einstellen der Zwei-Schritt-Bewegung des Produktgreiferelements 24 ermöglicht werden. Die beiden Nockenlaufbahnen 34, 35 umfassen jeweils ein erstes und ein zweites Profil 32, 33. Wie nachfolgend genauer erläutert wird, umfassen die Profile 32, 34 jeweils niedrige und hohe Positionsabschnitte zur Initialisierung der Schaltperioden der Vielzahl von Produktgreiferelementen 24.In the starting position 37, a dual-operated product gripper element 24 is in the retracted position shown. Along a periphery 18 of a first one paper-guiding cylinder 8, a plurality of product gripper elements 24 are arranged, which cooperate with a number of cutting elements 23. The Product gripper elements 24 each comprise a first section 24.1 and one second section 24.2 angled to the first section. A switching path 31, which here as two-lane track with the two cam tracks 34, 35 is shown is a first assigned paper-carrying cylinder 8. The switching path can also be two independently mutually adjustable raceways which have the corresponding tracks 34, 35, include. By means of two independent tracks 34, 35, an independent adjustment of the Two-step movement of the product gripper element 24 is made possible. The two Cam tracks 34, 35 each include a first and a second profile 32, 33. How explained in more detail below, the profiles 32, 34 each comprise low and high Position sections for initializing the switching periods of the plurality of Product gripper elements 24.

Das Produktgreiferelement 24 ist mit seinem zweiten Abschnitt 24.2 an der zweiten Schwenkachse 26 befestigt. Koaxial zu der zweiten Schwenkachse 26 ist ein Schaltelement 29, z.B. ein Nockenfolger 29 angebracht. Von der zweiten Schwenkachse 26 erstrecken sich zwei Verbindungsglieder 27, 28 zu einem ersten Schwenkpunkt 25 und zu einem zweiten Schaltelement 30, z.B. einem Nockenfolger, der dem Profil der zweiten Nockenlaufbahn 35 folgt. An der Zylinderoberfläche 18 des ersten papierführenden Zylinders 8 ist eine Nut 36 dargestellt, die das Gegenstück 23 aufnimmt, z.B. eine Nutenleiste mit dem die Messer des Messerzylinders 3 gemäß Fig. 1 bei einem Schneidvorgang zusammenwirken.The second section 24.2 of the product gripper element 24 is on the second Swivel axis 26 attached. A switching element is coaxial with the second pivot axis 26 29, e.g. a cam follower 29 is attached. Extend from the second pivot axis 26 two connecting links 27, 28 to a first pivot point 25 and to one second switching element 30, e.g. a cam follower that matches the profile of the second Cam track 35 follows. On the cylinder surface 18 of the first paper-carrying Cylinder 8 is shown a groove 36 which receives the counterpart 23, e.g. a Groove strip with which the knife of the knife cylinder 3 according to FIG. 1 at one Interact cutting process.

Fig. 3 zeigt das sich über die Oberfläche des papierführenden Zylinders erstreckende Produktgreiferelement in mittlerer Position. Fig. 3 shows that extending over the surface of the paper-guiding cylinder Product gripper element in the middle position.

Gemäß dieser Anordnung wird die zweite Schwenkachse 26 von dem ersten Bahnprofil der ersten Spur 34 nach oben bewegt. Die zweite Schwenkachse 26 kann anhand des hohen Positionsabschnitts durch leichte Rotation an dem ortsfesten Schwenkpunkt 25 in die ausgefahrene Position gebracht werden. Wie hier schematisch angedeutet ist, wird das Schaltelement 29, an dem das Greiferelement 24 angebracht ist, von dem Nockenfolger 29 ausgefahren, der der ersten Spur 34 der Bahn 31 folgt. Der Öffnungsgrad des Greiferelements 24, also der Abstand des ersten Abschitts 24.1 zur Vorderkante des Abschnitts 40 kann verändert werden, indem die Spuren 34, 35 im Verhältnis zueinander eingestellt werden. Wenn das zweite Schaltelement 30 entlang des zweiten Bahnprofils 33 in einem niedrigen Positionsabschnitt fährt, bewegt das Bindeglied 28 das Schaltelement 29 gegen den Uhrzeigersinn, so dass ein großer Öffnungsgrad des Greiferelements 24 bewirkt wird. Daher können auch dickere Vorderkanten von Materialbahnen akkurat ergriffen werden, da alle Bahnstrangschichten auf einmal von dem ersten Abschnitt 24.1 des jeweiligen Greiferelements 24 in einer nach unten gerichteten Bewegung ergriffen werden. Die Bewegung des Greiferelements 24, dargestellt in Fig. 3, entspricht dem ersten Schritt, d.h. einer mittleren Position 38 des Greiferelements 24. An diesem Punkt hat sich das Greiferelement 24 nach dem vorbestimmten Grad je nach Dicke der Vorderkante der Materialbahn, die erfindungsgemäß in dem Falzapparat 1 verarbeitet werden soll, geöffnet.According to this arrangement, the second pivot axis 26 is from the first path profile first track 34 moved up. The second pivot axis 26 can be based on the high Position section by slight rotation at the fixed pivot point 25 in the extended position. As indicated schematically here, this will be Switching element 29, on which the gripper element 24 is attached, by the cam follower 29 extended, which follows the first track 34 of the track 31. The opening degree of the Gripper element 24, that is the distance of the first section 24.1 from the front edge of the Section 40 can be changed by the tracks 34, 35 in relation to each other can be set. If the second switching element 30 along the second path profile 33 runs in a low position portion, the link 28 moves the switching element 29 counterclockwise, so that a large degree of opening of the gripper element 24 is effected. Therefore, thicker leading edges of material webs can also be accurate are taken, since all web strand layers at once from the first section 24.1 of the respective gripper element 24 in a downward movement become. The movement of the gripper element 24, shown in FIG. 3, corresponds to the first Step, i.e. a middle position 38 of the gripper element 24. At this point the gripper element 24 according to the predetermined degree depending on the thickness of the leading edge of the Material web, which is to be processed in the folder 1 according to the invention, opened.

Nach der mittleren Position 38, die in der vorherigen Fig. 3 beschrieben ist, nimmt das Produktgreiferelement 24 nun im Bezug auf die Position der Vorderkante 40, wie in Fig. 4 gezeigt, eine geschlossene Position 39 ein. Nachdem die zweite Schwenkachse 26 und dementsprechend das zweite Schwenkelement 29 in die erhöhte Position gebracht worden sind, wird der zweite Bewegungsschritt, das Schließen des Produktgreiferelements 24 dadurch erreicht, dass das zweite Schaltelement 30 einen hohen Positionsabschnitt der ihm zugeordneten zweiten Spur 35, die ein zweites Schaltprofil 33 umfasst, kontaktiert. Mittels eines zweiten Bindeglieds 28 wird die zweite Schwenkachse 26 im Uhrzeigersinn bewegt, wodurch das Produktgreiferelement 24 stark abwärts bewegt wird und die Vorderkante einer Materialbahn oberhalb der Position der Vorderkante kontaktiert, die mit dem Bezugszeichen 40 versehen ist. Je nach Höhe der Abschnittsposition der ersten Spur 34 und je nach Tiefe der Abschnittsposition der zweiten Spur 35 wird der Öffnungsgrad des Greiferelements 24 bestimmt und kann verändert werden. Andererseits kann anhand mit der Höhe der Abschnittsposition der zweiten Spur 35 der Betrag verändert werden, um den der erste Abschnitt 24.1 des Produktgreiferelements 24 im Verhältnis zu der Vorderkante der Signatur der Bahn nach unten bewegt wird. Durch das Einstellen der beiden unabhängig voneinander einstellbaren Schaltbahnen 34, 35 aufeinander, kann der Grad des Schließens und das Ausmaß der Greiferkraft, die auf die Vorderkante ausgeübt wird, individuell an die Anforderungen an den Druckauftrag angepasst werden.After the middle position 38, which is described in the previous FIG. 3, this takes Product gripper element 24 now in relation to the position of the leading edge 40, as in FIG. 4 shown a closed position 39 a. After the second pivot axis 26 and accordingly, the second pivot element 29 has been brought into the elevated position the second movement step, the closing of the product gripper element 24 thereby achieved that the second switching element 30 has a high position section of it assigned second track 35, which comprises a second switching profile 33 contacted. Means a second link 28, the second pivot axis 26 is moved clockwise, whereby the product gripper element 24 is moved strongly downward and the leading edge a web of material above the position of the leading edge contacted with the Reference numeral 40 is provided. Depending on the height of the section position of the first track 34 and depending on the depth of the section position of the second track 35, the opening degree of the Gripper element 24 is determined and can be changed. On the other hand, with the height of the section position of the second track 35 can be changed by the amount the first section 24.1 of the product gripper element 24 in relation to the front edge the signature of the web is moved down. By setting the two independently of each other adjustable switching paths 34, 35 on each other, the degree of Closing and the amount of gripper force exerted on the leading edge can be individually adapted to the requirements of the print job.

Das Zwei-Schritt-Greifen kann auch durch eine elektrisches Schalten des Greiferelements 24, z.B. anhand von Elektromotoren durchgeführt werden. Das erfindungsgemäße Produktgreiferelement 24 wird in Falzapparaten an papierführenden Zylindern, wie z.B. Sammel-, Falz- und/oder Klappenzylindern eingesetzt. The two-step gripping can also be done by electrically switching the gripper element 24, e.g. be carried out using electric motors. The invention Product gripper element 24 is used in folders on paper-guiding cylinders, e.g. Collection, folding and / or flap cylinders used.
