Description

Die Erfindung betrifft einen Falzapparat einer Rollenrotationsdruckmaschine.The invention relates to a folder of a web-fed rotary printing press.

An Falzzylindern von Falzapparaten von Rollenrotationsdruckmaschinen werden Arbeitselemente, z. B. Punkturen, Falzklappen oder Greifer, mittels Kurvengetrieben für die Annahme und Abgabe von Produkten gesteuert. Wahlweise kann auch die Annahme eines Produktes abgestellt werden. Hierzu besteht die Kurvenscheibe aus einer ersten und einer zweiten Scheibe, die koaxial nebeneinander angeordnet sind. Für den Fall, dass kein Produkt abgenommen werden soll, wird eine Scheibe derart verdreht, dass sie einen Steuerbereich der anderen Scheibe überdeckt. Die Kurvenrolle ist so breit ausgeführt, dass sie beide Scheiben überdeckt. Vorteilhaft ist die Kurvenrolle ballig ausgeführt, um einen Kantenlauf bei einer Schiefstellung auszugleichen.At folding cylinders of folders of web-fed rotary printing press working elements, eg. As punctures, jaws or gripper, controlled by cam mechanisms for the acceptance and delivery of products. Alternatively, the acceptance of a product can be turned off. For this purpose, the cam consists of a first and a second disc, which are arranged coaxially side by side. In the event that no product is to be removed, a disc is rotated so that it covers a control area of the other disc. The cam follower is so wide that it covers both discs. Advantageously, the cam roller is executed crowned to compensate for edge run at a misalignment.

Nachteilig ist bei diesem Kurvengetriebe, dass die Kurvenrolle vornehmlich im aneinandergrenzenden Bereich der beiden Scheiben aufliegt. Dies kann ein Ausbrechen der Scheibenkanten bewirken. Außerdem sind die Kanten von Hand entgratet und weisen eine entsprechend unregelmäßige, grobe Oberfläche auf, die starken Verschleiß an der Kurvenrolle bewirkt.A disadvantage of this cam gear that the cam roller rests primarily in the adjacent region of the two discs. This can cause the disc edges to break off. In addition, the edges are deburred by hand and have a correspondingly irregular, rough surface, which causes heavy wear on the cam roller.

Statt einer beide Scheiben überdeckenden Kurvenrolle wurden auch bereits zwei jeweils einer Scheibe zugeordnete Kurvenrollen vorgesehen. Diese beiden Kurvenrollen schlagen jedoch mit einer größeren Gesamtmasse und entsprechend nachteiligen Trägheitskräften zu Buche. Außerdem wird bei einer Ausbiegung der Drehachse des Rollenhebels eine Rolle mehr abgehoben, wodurch beim späteren Aufsetzen Stöße verursacht werden. Weiterhin bleibt eine Kurvenrolle stehen oder verlangsamt ihre Drehzahl, wenn sie mittels der anderen Scheibe von der ihr zugeordneten Scheibe abgehoben wurde. Beim Wiederaufsetzen auf die Scheibe muss die Kurvenrolle beschleunigt werden, was mit Stößen und Verschleiß verursachendem Schlupf einhergeht.Instead of a cam roller covering both discs, two cam rollers each assigned to one disc have already been provided. However, these two cam rollers have a larger total mass and corresponding disadvantageous inertial forces to book. In addition, in a deflection of the axis of rotation of the roller lever one more role lifted, causing shocks during later placement. Furthermore, a cam roller stops or slows down their speed when it was lifted by means of the other disc from its associated disc. When replacing the disc The cam roller must be accelerated, which is accompanied by shock and wear causing slip.

Aus der DE 101 13 165 A ist es auch bereits bekannt, den Verschleiß der Rollenkurven von Bogenübergabetrommel für Bogendruckmaschinen zu reduzieren, in dem diese zwei konvexe Erhebungen aufweisen, die an den zu einander angrenzenden bzw. nebeneinander liegende Scheiben anliegen.From DE 101 13 165 A, it is also already known to reduce the wear of the roller curves of sheet transfer drum for sheet-fed presses, in which they have two convex protrusions which bear against the adjacent to each other or adjacent discs.

Es ist Aufgabe der Erfindung, ein Kurvengetriebe für Zylinder in einem Falzapparat zu schaffen, das gute kinematische Eigenschaften aufweist, wobei die Kanten der Kurvenscheiben geringem Verschleiß unterworfen sind.It is an object of the invention to provide a cam mechanism for cylinders in a folder having good kinematic properties, wherein the edges of the cams are subjected to low wear.

Die Aufgabe wird mit den Merkmalen des Patentanspruchs 1 gelöst. Die vorgeschlagene Kurvenrolle zeichnet sich durch eine geringe Masse aus, wodurch entsprechende kinematischen Kräfte klein gehalten werden. Außerdem wird dank der konvexen Wölbungen ein Kantenlauf der Kurvenrolle vermieden. Auch läuft die Kurvenrolle mit ihren Wölbungen jeweils im mittigen Bereich der zugehörigen Scheiben, wodurch letztere an ihren Kanten nicht beschädigt werden und mit diesen Kanten nicht die Kurvenrolle verletzen. Die Kurvenrolle kann außerdem schmaler ausgeführt werden, wodurch im Falle von Ausbiegungen der Rollenhebelachse das Abheben einer konvexen Wölbung minimiert wird. Schließlich wird auch beim Überqueren eines tiefliegenden Bereiches einer Scheibe die Kurvenrolle auf Drehzahl gehalten, wodurch sich ein nachfolgendes Beschleunigen mit einhergehenden Stößen und reibendem Schlupf erübrigt.The object is achieved with the features of claim 1. The proposed cam roller is characterized by a low mass, whereby corresponding kinematic forces are kept small. In addition, an edge run of the cam roller is avoided thanks to the convex curvatures. Also, the cam roller runs with their bulges in each case in the central region of the associated discs, whereby the latter are not damaged at their edges and do not hurt with these edges the cam roller. The cam roller can also be made narrower, which in the case of deflections of the roller lever axis, the lifting of a convex curvature is minimized. Finally, even when crossing a low-lying area of a disc, the cam roller is kept at speed, whereby a subsequent acceleration with associated shocks and friction slip is unnecessary.

Weitere Merkmale und Vorteile ergeben sich aus den Unteransprüchen in Verbindung mit der Beschreibung.Other features and advantages will become apparent from the dependent claims in conjunction with the description.

Die Kurvenrolle 7 läuft bei Rotation des Falzklappenzylinders 1 auf einer ersten und einer zweiten Scheibe 8, 9 einer Kurvenscheibe 10 ab. Die erste und zweite Scheibe 8, 9 sind koaxial nebeneinander angeordnet. Sie sind gegeneinander verdrehbar, wobei beispielsweise die erste Scheibe 8 gestellfest angeordnet ist und die zweite Scheibe 9 mit nicht gezeigten Mitteln gegenüber der ersten Scheibe 8 verdrehbar ist.The jaw cylinder 1 shown in the side view in Figure 1 includes a fixed and a controlled jaw 2, 3. The controlled jaw 3 is fixed to an axis 5 rotatably mounted in the cylinder body 4. Furthermore, a roller lever 6 together with cam roller 7 is attached to the axle 5. The cam roller 7 starts at Rotation of the jaw cylinder 1 on a first and a second disc 8, 9 of a cam 10 from. The first and second discs 8, 9 are arranged coaxially next to one another. They are mutually rotatable, for example, the first disc 8 is arranged fixed to the frame and the second disc 9 with means not shown relative to the first disc 8 is rotatable.

Die Kurvenrolle 7 ist als Wälzlager ausgeführt (Figur 2), der Rollenhebel 6 vorteilhaft als Gabelhebel. Der Innenring 11 der Kurvenrolle 7 ist auf einem in den Rollenhebel 6 gesteckten Rollenbolzen 12 gelagert. Der Außenring 13 der Kurvenrolle 7 trägt am Außenmantel in Umfangsrichtung umlaufend, nebeneinander angeordnet zwei konvexe Wölbungen 14, 15, wobei jede Wölbung 14, 15 mit einer Scheibe 8, 9 zusammenarbeitet. Eine Vertiefung 16 zwischen den konvexen Wölbungen 14, 15 kommt über dem aneinandergrenzenden Bereich der Scheiben 8, 9 zu liegen. Jede konvexe Wölbung 14, 15 ist vorteilhaft als Kreisbogen ausgeführt, dessen Radius R im Bereich 300 mm ≤ R ≤ 600 mm ausgewählt wurde. Die konvexen Wölbungen können auch als anderweitige geometrischen Kurven ausgeführt werden.The cam roller 7 is designed as a rolling bearing (Figure 2), the roller lever 6 advantageous as a fork lever. The inner ring 11 of the cam roller 7 is mounted on a roller pin 6 inserted in the roller bolt 12. The outer ring 13 of the cam roller 7 carries on the outer shell circumferentially circumferentially, juxtaposed two convex curvatures 14, 15, each curvature 14, 15 cooperates with a disc 8, 9. A depression 16 between the convex curvatures 14, 15 comes to rest over the contiguous region of the discs 8, 9. Each convex curvature 14, 15 is advantageously designed as a circular arc, the radius R was selected in the range 300 mm ≤ R ≤ 600 mm. The convex curves can also be performed as other geometric curves.

Bei Drehung des Falzklappenzylinders 1 in der in Figur 1 angegebenen Richtung läuft die Kurvenrolle 7 auf den Scheiben 8, 9 ab, wobei diese bei der gezeigten Stellung der Scheibe 9 nicht in das Tal der Scheibe 8 eintauchen kann und die gesteuerte Falzklappe 3 geöffnet bleibt. Bei einer Verdrehung der Scheibe 9 derart, dass deren Tal mit dem Tal der Scheibe 8 zur Deckung kommt, taucht die Kurvenrolle 7 in diese Täler ein, wobei die Falzklappe 3 geschlossen wird.Upon rotation of the jaw cylinder 1 in the direction indicated in Figure 1, the cam roller 7 runs on the discs 8, 9, which in the position shown the disc 9 can not dip into the valley of the disc 8 and the controlled jaw 3 remains open. With a rotation of the disc 9 such that its valley comes to coincide with the valley of the disc 8, the cam roller 7 dives into these valleys, the jaw 3 is closed.

Mit dem beschriebenen Kurvengetriebe können auch Punkturen oder Greifer gesteuert werden. In Figur 1 ist als weitere Variante gestrichelt eine Punkturleiste 17 angedeutet, die statt der Falzklappe 3 an der Achse 5 befestigt sein kann. Die Punkturleiste 17 ist mit Klammerposition angegeben.With the described cam mechanism also punctures or grippers can be controlled. In Figure 1 is indicated as a further variant by dashed lines a spur strip 17, which may be attached to the axis 5 instead of the jaw 3. The sprocket 17 is indicated with bracket position.

Die Kurvenrolle 7 kann auch an einem Stößel 18 befestigt sein, der in einem Falzzylinder geradegeführt wird. Gemäß Figur 3 handelt es sich um einen Greiferzylinder 19, der eine Greiferleiste 20 trägt. Letztere ist an einer Achse 5.1 befestigt, die drehbar im Greiferzylinder 19 gelagert ist. An der Achse 5.1 ist weiterhin ein Hebel 21 befestigt, der mittels einer Koppel 22 mit dem Stößel 18 in Antriebsverbindung steht. Die Kurvenrolle 7 arbeitet mit einer Kurvenscheibe 10.1 zusammen, die als Innenkurve ausgebildet ist. Die Kurvenscheibe 10.1 besteht aus einer ersten und einer zweiten Scheibe 8.1, 9.1, die analog wie die Scheiben 8 und 9 des vorherigen Ausführungsbeispiels ausgeführt und gegeneinander verdrehbar sind. Ebenso hat die Kurvenrolle 7.1 der Kurvenrolle 7 ähnelnde Konturen im Außenmantel.The cam roller 7 may also be attached to a plunger 18 which is straightened in a folding cylinder. According to FIG. 3, a gripper cylinder 19 carrying a gripper bar 20 is shown. The latter is on an axis 5.1 fastened, which is rotatably mounted in the gripper cylinder 19. On the axis 5.1, a lever 21 is further attached, which is connected by means of a coupling 22 with the plunger 18 in drive connection. The cam roller 7 cooperates with a cam 10.1, which is formed as an inner curve. The cam 10.1 consists of a first and a second disc 8.1, 9.1, which are analogous to the discs 8 and 9 of the previous embodiment executed and rotated against each other. Similarly, the cam roller 7.1 of the cam roller 7 has similar contours in the outer jacket.

Bei der Rotation des Greiferzylinders 19 läuft die Kurvenrolle 7.1 auf den Scheiben 8.1 und 9.1 ab. Wenn deren nicht gezeigten Ausnehmungen (Täler) zur Deckung gebracht wurden, bewegt sich die Kurvenrolle 7.1 mit dem Stößel 18 radial in das Tal hinein, wobei die Greifer der Greiferleiste 20 schließen.During rotation of the gripper cylinder 19, the cam roller 7.1 runs on the discs 8.1 and 9.1. If their not shown recesses (valleys) were brought to coincide, the cam roller moves 7.1 with the plunger 18 radially into the valley, the gripper of the gripper bar 20 close.

An einem Falzzylinder 1, 19 können mehrere Rollenhebel 6 oder Stößel 18 angeordnet sein, die mit einer Kurvenscheibe 10, 10.1 zusammenarbeiten.At a folding cylinder 1, 19 more roller lever 6 or plunger 18 may be arranged, which cooperate with a cam 10, 10.1.
