At least one closing block of the closing cylinder can be adjusted in conjunction with the stitching head.

Description

Die vorliegende Erfindung betrifft einen Heftapparat mit einem mindestens einen Heftkopf tragenden Heftzylinder gemäß dem Oberbegriff des Anspruches 1, 2 oder 3.The present invention relates to a stapler with a stapling cylinder carrying at least one stapling head according to the preamble of claim 1, 2 or 3.

Derartige Heftapparate umfassen herkömmlicherweise einen Heftzylinder mit einem oder mehreren Heftköpfen und einen Schließzylinder, die jeweils um eine Rotationsachse drehbar sind und zwischen sich einen Spalt begrenzen, den die zu heftenden Druckerzeugnisse, insbesondere in einer Rollenrotationsdruckmaschine erzeugten Druckerzeugnisse, durchlaufen und dabei geheftet werden, wobei der Schließzylinder dem Heftkopf als Widerlager dient.Such staplers conventionally comprise a stapling cylinder with one or more stapling heads and a lock cylinder which are each rotatable about an axis of rotation and define therebetween a gap through which the printed products to be stapled, in particular in a web-fed rotary printing press, pass through and are stapled; Lock cylinder the stapling head serves as an abutment.

Die Zahl der zum Heften eines Druckerzeugnisses benötigten Heftklammern und ihr Abstand von einander hängt von der Länge der Falzlinie ab, entlang derer das Druckerzeugnis gefalzt und geheftet wird. Meist werden zwei oder drei Klammern eingesetzt. Wenn nacheinander Druckerzeugnisse mit unterschiedlichen Abmessungen verarbeitet werden sollen, kann beim Wechsel des Erzeugnisses eine umständliche Anpassung des Heftapparats erforderlich werden.The number of staples needed to staple a printed product and their distance from each other depends on the length of the fold line along which the printed product is folded and stapled. Usually two or three brackets are used. If successive printed products are to be processed with different dimensions, a cumbersome adjustment of the stapler may be required when changing the product.

Die DE 38 10 457 A1 offenbart eine Rotationshefteinrichtung, deren Heftköpfe axial verschiebbar sind.The DE 38 10 457 A1 discloses a rotary stapler whose stapling heads are axially displaceable.

Der Erfindung liegt die Aufgabe zugrunde, einen Heftapparat mit einem mindestens einen Heftkopf tragenden Heftzylinder zu schaffen.The invention has for its object to provide a stapler with a stapling head carrying at least a stapling cylinder.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1, 2 oder 3 gelöst.The object is achieved by the features of claim 1, 2 or 3.

Ein wichtiger Vorteil des erfindungsgemäßen Heftapparates ist, dass er eine schnelle Anpassung der Position der Heftköpfe an die Abmessungen eines zu verarbeitenden Druckerzeugnisses erlaubt, ohne dass hierfür Teile ab- und wieder anmontiert werden müssen. Eine einfache Verschiebung der Heftköpfe ermöglicht eine schnelle Anpassung an wechselnde Formate.An important advantage of the stapler according to the invention is that it allows a quick adjustment of the position of the stapling heads to the dimensions of a printed product to be processed, without the need for parts off and must be mounted again. A simple shift of the stitching heads allows a quick adaptation to changing formats.

Der mit dem Heftzylinder zusammenwirkende Schließzylinder trägt herkömmlicherweise Schließblöcke, die an ihrer den Heftköpfen zugewandten Seite Vertiefungen zum Führen der Schenkel einer Heftklammer während des Heftens tragen. Diese Schließblöcke sind zweckmäßigerweise zusammen mit den Heftköpfen verschiebbar.The cooperating with the stitching cylinder lock cylinder conventionally has closing blocks, which carry on its side facing the stitching heads recesses for guiding the legs of a staple during stapling. These closing blocks are expediently displaceable together with the stapling heads.

Vorzugsweise sind zu diesem Zweck zwei Getriebe jeweils zum Umsetzen einer Drehbewegung in eine Verschiebung wenigstens eines der Heftköpfe bzw. wenigstens eines der Schließblöcke vorgesehen, und die Getriebe sind derart aneinander gekoppelt, dass sie Bewegungen des Heftkopfes und des Schließblocks jeweils über gleiche Strecken antreiben.Preferably, for this purpose, two gears are each provided for converting a rotational movement into a displacement of at least one of the stitching heads or at least one of the closing blocks, and the gearboxes are coupled to each other such that they drive movements of the stitching head and the closing block respectively over equal distances.

Eine jedem Heftkopf zugeordnete Heftdraht-Versorgungsvorrichtung ist vorzugsweise ebenfalls verschiebbar; auch ihre Verschiebung ist sinnvollerweise durch ein Getriebe antreibbar, das mit dem des Heftkopfes gekoppelt ist, so dass sich Heftkopf und Heftdraht-Versorgungsvorrichtung jeweils über gleiche Strecken verschieben.A stitching wire supply device associated with each stitching head is preferably also displaceable; Their displacement is usefully drivable by a gear that is coupled to that of the stapling head, so that stapling head and stitching wire supply device each move over the same distances.

Zum Umsetzen einer Drehung in eine Verschiebung eines Heftkopfes, eines Schließblocks oder einer Heftdraht-Versorgungsvorrichtung wird vorzugsweise eine Gewindespindel eingesetzt.To implement a rotation in a displacement of a stapling head, a closing block or a stitching wire supply device, a threaded spindle is preferably used.

Diese hat vorzugsweise zwei gegenläufige Gewindeabschnitte, um jeweils zwei Heftköpfe, Schließblöcke oder Heftdraht-Versorgungsvorrichtungen gegenläufig zu verschieben.This preferably has two counter-rotating threaded sections, in each case two stitching heads, closing blocks or stitching wire supply devices in opposite directions move.

Im Falle der Heftköpfe bzw. Schließblöcke ist eine solche Spindel vorzugsweise koaxial im Heftzylinder bzw. Schließzylinder gehalten.In the case of the stitching heads or closing blocks such a spindle is preferably held coaxially in the stitching cylinder or lock cylinder.

Um einerseits am stehenden Heftapparat eine Verschiebung durch Drehen der Spindel zu ermöglichen, andererseits aber zu verhindern, dass eine Drehung der Zylinder selbst eine solche Verschiebung antreibt, ist die Spindel vorzugsweise über ein Ausgleichsgetriebe mit einer Stellwelle und mit dem Zylinder, in dem sie gehalten ist verbunden, und das Übersetzungsverhältnis des Ausgleichsgetriebes ist so gewählt, dass bei stehender Stellwelle die Spindel und der Zylinder mit gleicher Drehzahl rotieren.On the one hand to allow the stationary stapler to shift by turning the spindle, but on the other hand to prevent rotation of the cylinder itself driving such a displacement, the spindle is preferably via a differential gear with a control shaft and with the cylinder in which it is held connected, and the transmission ratio of the differential gear is selected so that rotate the spindle and the cylinder at the same speed when the actuating shaft is stationary.

Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im Folgenden beschrieben.Embodiments of the invention are illustrated in the drawings and will be described below.

Fig. 1 ist eine perspektivische Ansicht eines Heftapparates, wobei Seitengestellplatten, ar denen die diversen Zylinder des Heftapparates gelagert sind, sowie Komponenten, die der Zufuhr der zu heftenden Druckerzeugnisse zu Heft- und Schließzylinder dienen, der Übersichtlichkeit halber nicht gezeigt sind. Fig. 1 is a perspective view of a stapler, wherein side frame plates, where the various cylinders of the stapler are stored, as well as components that are used to supply the stapled printed products to stapling and lock cylinder, for clarity, are not shown.

Der in den Seitengestellplatten um eine Achse A drehbar gelagerte Heftzylinder 01 trägt zwei schematisch dargestellte Heftköpfe 02, die mit jeder Umdrehung des Heftzylinders 01 ein an einer dem Heftkopf 02 zugeordneten Heftdraht-Versorgungsvorrichtung 03 dargebotenes Drahtstück 04 greifen, abtrennen und zu einer Klammer biegen, um mit der Klammer anschließend ein Druckerzeugnis zu heften, das einen Spalt 06 zwischen dem Heftzylinder 01 und einem Schließzylinder 07 durchläuft.The in the side frame plates about an axis A rotatably mounted stapling cylinder 01 carries two stitching heads 02 shown schematically, which grab with each revolution of the stapling cylinder 01 a on a stapling head 02 associated stapling wire supply device 03 dargebotenes piece of wire 04, and bend into a clip to staple with the clip then a printed product that has a gap 06 passes between the stitching cylinder 01 and a lock cylinder 07.

Heftzylinder 01 und Schließzylinder 07 tragen an ihren axialen Enden zwei Zahnräder 08 bzw. 09, die über zwei Zwischenzahnräder 10; 11 aneinander gekoppelt sind. Ein gemeinsamer, nicht dargestellter Antriebsmotor greift an einem der Zahnräder 08; 09; 10 oder 11 an. Die Zahnzahlen der Zahnräder 08; 09; 10; 11 sind so gewählt, dass beide Zylinder 01; 07 mit gleicher oder der Heftkopfanzahl entsprechender Drehzahl rotieren.Stapling cylinder 01 and lock cylinder 07 carry at their axial ends two gears 08 and 09, via two idler gears 10; 11 are coupled together. A common, not shown drive motor engages one of the gears 08; 09; 10 or 11 on. The numbers of teeth of the gears 08; 09; 10; 11 are chosen so that both cylinders 01; 07 with the same or the stapling head number corresponding speed rotate.

Im Inneren der hohlen Zylinder 01; 07 ist jeweils koaxial eine Spindel 12 angeordnet, die in Fig. 1 nur am Heftzylinder 01 zu erkennen ist. Die zwei Heftköpfe 02 des Heftzylinders 01 greifen durch einen Schlitz 13 in dessen hohlem Mantel hindurch und weisen jeweils in einem in den Mantel eingreifenden Abschnitt eine Bohrung mit Innengewinde auf, die mit der Spindel 12 kämmt. Die zwei Heftköpfe 02 befinden sich an Abschnitten 12a; 12b (siehe Fig. 2) der Spindel 12 mit jeweils entgegengesetzt gleicher Gewindesteigung, so dass eine Drehung der Spindel 12 in Bezug auf den Heftzylinder 01 entgegengesetzt gleiche Bewegungen der Heftköpfe 02 entlang der Achse A hervorruft. Die Schließblöcke 14 des Schließzylinders 07 sind an diesem in gleicher Weise mit Hilfe der in dessen hohlen Innerem geführten Spindel 12 verschiebbar.Inside the hollow cylinder 01; 07 is coaxially arranged a spindle 12, which in Fig. 1 can only be seen on the stapling cylinder 01. The two stitching heads 02 of the stapling cylinder 01 engage through a slot 13 in its hollow shell and each have a bore with an internal thread in a section engaging in the shell, which meshes with the spindle 12. The two stitching heads 02 are located at sections 12a; 12b (see Fig. 2 ) of the spindle 12 with in each case opposite equal pitch, so that rotation of the spindle 12 in relation to the stitching cylinder 01 causes opposite movements of the stapling heads 02 along the axis A. The closing blocks 14 of the lock cylinder 07 are displaceable on this in the same way with the help of the spindle 12 guided in the hollow interior thereof.

Aus dem Heftzylinder 01 und dem Schließzylinder 07 ist jeweils axial eine Stellwelle 16 herausgeführt, die, wie in Fig. 2 gezeigt, über ein Ausgleichsgetriebe 17, nämlich ein zweistufiges Planetengetriebe 17, an die Spindel 12 gekoppelt ist. Bei der in Fig. 2 schematisch gezeigten Ausgestaltung sind die Stellwelle 16 und die Spindel 12 jeweils mi einem Sonnenrad 18 bzw. 19 einer Stufe des Planetengetriebes 17 verbunden, und ein Hohlrad 21 ist fest mit dem Zahnrad 08 bzw. 09 verbunden, über das der betreffende Zylinder 01 im Betrieb des Heftapparats drehangetrieben wird. Fig. 2 zeigt das Zahnrad 08 direkt am Planetengetriebe 17; in der Ansicht der Fig. 1 befinden sich beide an verschiedenen Enden des Heftzylinders 01 und sind durch dessen starren Mantel gekoppelt.From the stapling cylinder 01 and the lock cylinder 07, an adjusting shaft 16 is led out in each case axially, which, as in Fig. 2 shown, via a differential gear 17, namely a two-stage planetary gear 17 is coupled to the spindle 12. At the in Fig. 2 schematically shown embodiment, the control shaft 16 and the spindle 12 are each mi a sun gear 18 and 19 of a stage of the planetary gear 17 is connected, and a ring gear 21 is fixedly connected to the gear 08 and 09, via which the relevant Cylinder 01 is rotated during operation of the stapler. Fig. 2 shows the gear 08 directly on the planetary gear 17; in the view of Fig. 1 Both are located at different ends of the stapling cylinder 01 and are coupled by its rigid shell.

Es kommt außer einem Planetengetriebe 17 auch eine beliebige andere Ausgleichsgetriebekonstruktion, z.B. ein Harmonic-Drive-Getriebe in Betracht, sofern sichergestellt ist, dass zwischen den drei Anschlüssen des Getriebes ein solches Übersetzungsverhältnis gilt, dass bei stehender Stellwelle 16 der Zylinder 01 bzw. 07 und die darin befindliche Spindel 12 mit gleicher Drehgeschwindigkeit rotieren, so dass im Betrieb die Heftköpfe 02 bzw. Schließblöcke 14 nicht entlang der Achse A; D wandern.There is also, besides a planetary gear 17, any other differential gear design, e.g. a harmonic drive gear, provided that it is ensured that between the three ports of the transmission such a ratio applies that at standing actuator shaft 16 of the cylinder 01 and 07 and the spindle 12 therein rotate at the same rotational speed, so that in Do not operate the stapling heads 02 or closing blocks 14 along the axis A; D hiking.

Des weiteren ist auch ein Servoantrieb (gekoppelt oder nicht gekoppelt) je Achse vorstellbar oder ein Handantrieb.Furthermore, a servo drive (coupled or not coupled) per axle is conceivable or a manual drive.

Die Stellwellen 16 des Heftzylinders 01 und des Schließzylinders 07 sind durch einen um zwei Ritzel 22 geschlungenen Zahnriemen 23 gekoppelt. Die Durchmesser der Ritzel 22 sind gleich, so dass die Spindeln 12 sich jeweils gleich bewegen und deckungsgleiche Bewegungen der Heftköpfe 02 und der Schließblöcke 14 antreiben.The adjusting shafts 16 of the stitching cylinder 01 and the lock cylinder 07 are coupled by a toothed belt 23 wound around two pinions 22. The diameters of the pinions 22 are the same, so that the spindles 12 each move the same and drive congruent movements of the stitching heads 02 and the closing blocks 14.

Die Heftdraht-Versorgungsvorrichtungen 03 sind auf zwei fest mit den Seitenplatten verbundenen Führungsspindeln 24 parallel zur Achse A verschiebbar gehalten. Eine Gewindespindel 26, die wie die Gewindespindel 12 zwei Gewindeabschnitte mit entgegengesetzt gleicher Steigung aufweist, ist mit Innengewinden der Versorgungsvorrichtungen 03 im Eingriff und über ein weiteres Paar von Ritzeln 27 und einen Zahnriemen 28 an die Stellwelle 16 des Heftzylinders 01 gekoppelt. So folgen auch die Heftdraht-Versorgungsvorrichtungen 03 jeder Verstellung der Heftköpfe 02. Eine einzige Verstellbewegung genügt, um Heftköpfe 02, Versorgungsvorrichtungen 03 und Schließblöcke 14 unter exakter Beibehaltung ihrer Ausrichtung aufeinander zu verschieben.The stitching wire supply devices 03 are held on two fixedly connected to the side plates guide screws 24 parallel to the axis A slidably. A threaded spindle 26, which, like the threaded spindle 12, has two threaded portions of opposite equal pitch, is engaged with internal threads of the feeders 03 and coupled via another pair of pinions 27 and a toothed belt 28 to the actuating shaft 16 of the stapling cylinder 01. Thus, the stitching wire supply devices 03 follow every adjustment of the stitching heads 02. A single adjustment movement is sufficient to stitching heads 02, supply devices 03 and locking blocks 14 with exact retention of their orientation towards each other move.

Selbstverständlich könnte die Kopplung über Zahnriemen 23; 28 auch durch eine Kopplung über Zahnräder oder dergleichen ersetzt werden, die gewährleistet, dass die Gewindespindeln 12; 26 jeweils gleiche Drehwege zurücklegen.Of course, the coupling via toothed belt 23; 28 are also replaced by a coupling via gears or the like, which ensures that the threaded spindles 12; 26 each cover the same turning paths.

Fig. 3 zeigt eine Abwandlung des Schnitts der Fig. 2, bei der am Heftzylinder 01 drei Heftköpfe 02 angeordnet sind. Die Gewindespindel 12 erstreckt sich durch alle drei Heftköpfe 02, hat aber in ihrem mittleren Abschnitt, an dem der mittlere Heftkopf 02 angeordnet ist, kein Gewinde und kann daher frei rotieren, ohne den mittleren Heftkopf 02 zu verschieben. Dieser ist unmittelbar am Mantel des Heftzylinders 01 gegen axiale Verschiebung gesichert. Die zwei seitlichen Heftköpfe 02 halten stets gleichen Abstand zum mittleren Heftkopf 02 ein. Komplementär zum dritten Heftkopf ist selbstverständlich auch ein dritter Schließblock 14 am Schließzylinder 07 und eine dritte Heftdraht-Versorgungsvorrichtung 03 vorgesehen, die nicht eigens in einer Fig. dargestellt sind. Fig. 3 shows a modification of the section of the Fig. 2 in which three stapling heads 02 are arranged on the stapling cylinder 01. The threaded spindle 12 extends through all three stitching heads 02, but has no thread in its middle section, on which the middle stitching head 02 is arranged, and can therefore rotate freely without displacing the middle stitching head 02. This is secured directly on the jacket of the stapling cylinder 01 against axial displacement. The two lateral stapling heads 02 always maintain the same distance from the middle stapling head 02. Complementary to the third stapling head, of course, a third closing block 14 on the closing cylinder 07 and a third stapling wire feeding device 03 are also provided, which are not specifically shown in a figure.

Die Ausgestaltung der Fig. 4 weist zwei Gewindespindeln 12 auf, die sich jeweils nur übe eine Hälfte der Länge des Zylinders 01 erstrecken. Jede Gewindespindel 12 trägt einen Heftkopf 02 und ist durch ein Planetengetriebe 17 unabhängig von der anderen drehantreibbar. So können auch asymmetrische Positionen der Heftköpfe 02 (bzw. der Schließblöcke und der Heftdraht-Versorgungsvorrichtungen 03) in Bezug auf die Mittelebene des Heftapparates eingestellt werden.The design of the Fig. 4 has two threaded spindles 12, each extending over only half of the length of the cylinder 01. Each threaded spindle 12 carries a stapling head 02 and is rotatably driven by a planetary gear 17 regardless of the other. Thus, asymmetrical positions of the stitching heads 02 (or the closing blocks and the stitching wire supply devices 03) can also be adjusted with respect to the center plane of the stapler.
