Description

Die Erfindung betrifft einen Falzzylinder gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a folding cylinder according to the preamble of claim 1.

Derartige Falzzylinder mit einstellbarem Umfang sind z. B. aus US 58 46 177 A bzw. DE 295 02 957 U1 , DE 38 21 442 C2 und US 53 13 883 A bekannt.Such folding cylinder with adjustable circumference are z. B. off US 58 46 177 A respectively. DE 295 02 957 U1 . DE 38 21 442 C2 and US 53 13 883 A known.

Derartige Falzzylinder umfassen eine Mehrzahl von flexiblen Bändern, die an wenigstens zwei Stellen am Körper des Falzzylinders gehalten sind, wobei wenigstens eine erste dieser Stellen in Umfangsrichtung des Falzzylinders verschiebbar ist. Durch Verschieben zur zweiten Befestigungsstelle hin kann ein mittlerer Bereich der Bänder von dem Körper des Falzzylinders abgespreizt und so dessen Umfang in einem der Verschiebung der ersten Stellen entsprechenden Ausmaß vergrößert werden.Such folding cylinders comprise a plurality of flexible bands which are held at least two locations on the body of the folding cylinder, wherein at least a first of these locations is displaceable in the circumferential direction of the folding cylinder. By shifting toward the second attachment point, a central region of the bands can be spread apart from the body of the folding cylinder, thus enlarging its circumference to an extent corresponding to the displacement of the first positions.

Um für eine Gruppe nebeneinanderliegender Bänder diese Verschiebung in gleicher Weise anzutreiben, ist insbesondere aus DE 38 21 442 C2 bekannt, die verschiebbaren ersten Stellen der flexiblen Bänder mit einer in axialer Richtung des Falzzylinders verschiebbaren Leiste über ineinandergreifende Zapfen und schräg zur Umfangsrichtung des Zylinders und zu seiner Axialrichtung orientierte Langlöcher so zu koppeln, dass eine Verschiebung der Leiste in der Axialrichtung zu einer Bewegung der ersten Stellen der Bänder in Umfangsrichtung führt. Eine axiale Verschiebung der Leiste wird erreicht durch Drehen einer Gewindestange, die mit einem Innengewinde der Leiste im Eingriff ist. Um mehrere um den Umfang des Falzzylinders verteilte Gruppen von Bändern anzutreiben, ist zu jeder Gruppe jeweils eine solche Leiste am Falzzylinder angebracht. Um diese mehreren Leisten gleichförmig anzutreiben, sind deren Gewindestangen über einen Riemenmechanismus aneinander gekoppelt. Dieser Riemenmechanismus rotiert zusammen mit dem Falzzylinder. Dies macht das Verstellen des Riemenmechanismus kompliziert.In order to drive this shift in the same way for a group of adjacent bands is in particular from DE 38 21 442 C2 known to couple the displaceable first points of the flexible bands with a slidable in the axial direction of the folding cylinder bar via interengaging pins and obliquely to the circumferential direction of the cylinder and to its axial direction elongated holes so that a displacement of the bar in the axial direction to a movement of the first Make the bands in the circumferential direction leads. An axial displacement of the strip is achieved by turning a threaded rod which is in engagement with an internal thread of the strip. In order to drive a plurality of groups of bands distributed around the circumference of the folding cylinder, one such bar is attached to the folding cylinder for each group. To drive these multiple strips uniformly, the threaded rods are coupled via a belt mechanism to each other. This belt mechanism rotates together with the folding cylinder. This makes the adjustment of the belt mechanism complicated.

Die DE-AS 16 11 330 offenbart einen umfangsverstellbaren Falzzylinder, wobei eine Verstellung mehrerer Bänder mittels einer gemeinsamen Antriebskette erfolgt.The DE-AS 16 11 330 discloses a circumferentially adjustable folding cylinder, wherein an adjustment of multiple bands is effected by means of a common drive chain.

Die DD 136 593 A betrifft einen Falzmesserzylinder, dessen Durchmesser mittels Tragbügel variierbar ist. Dabei werden die Tragbügel mittels im Zylinderkörper verstellbarer Keilleisten eingestellt.The DD 136 593 A relates to a folding blade whose diameter is variable by means of mounting bracket. The mounting brackets are adjusted by means of adjustable in the cylinder body wedge strips.

Der Erfindung liegt die Aufgabe zugrunde, einen Falzzylinder zu schaffen, dessen Umfang an die Verarbeitung unterschiedlicher Produkte angepasst werden kann.The invention has for its object to provide a folding cylinder, the scope of which can be adapted to the processing of different products.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of claim 1.

Vorteilhaft ist, dass der Umfang des Falzzylinders zur Anpassung an die Verarbeitung von Produkten unterschiedlicher Länge, sowie zur Anpassung durch die Dicke eines Produktes variierende Papierwege/Bahnspannung einstellbar ist.It is advantageous that the circumference of the folding cylinder is adjustable to adapt to the processing of products of different lengths, and for adapting through the thickness of a product varying paper paths / web tension.

Ein wichtiger Vorteil des Falzzylinders ist, dass er es ermöglicht, identische Stellverschiebungen auch mehrerer als Leisten ausgebildete Stellelemente verschiedener Gruppen am Falzzylinder zu realisieren, ohne dass hierfür ein aufwendiger, mit dem Falzzylinder rotierender Kopplungsmechanismus erforderlich ist.An important advantage of the folding cylinder is that it makes it possible to realize identical adjusting displacements of a plurality of adjusting elements of different groups formed on the folding cylinder, without the need for a complex coupling mechanism rotating with the folding cylinder.

Der Erfindung zufolge ist der Anschlagring, gegen den die Leiste gedrückt ist, an einem Falzapparat ortsfest, und ein Kopfabschnitt der Leiste ist entlang der Oberfläche des Anschlagrings bewegbar.According to the invention, the stop ring against which the strip is pressed is fixed to a folder, and a head portion of the strip is movable along the surface of the stop ring.

Ein solcher bewegbarer Kopfabschnitt ist vorzugsweise durch ein an der Leiste drehbar gehaltenes Rad gebildet.Such a movable head portion is preferably formed by a wheel rotatably supported on the bar.

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

Am Körper des in Fig. 1 gezeigten Falzzylinders 01 sind drei Gruppen von flexiblen Bändern 02 jeweils in einem Winkelabstand von 120° in Umfangsrichtung angeordnet von denen zwei in der Fig. 1 zu sehen sind. Jeder dieser Gruppen ist eine parallel zur Achse des Falzzylinders 01 verschiebbare Leiste zugeordnet, deren Funktion noch genauer erläutert wird. Die Bänder 02 begrenzen zwischen sich jeweils eine Mehrzahl von Schlitzen 03. An der in der Fig. 1 oben liegenden Gruppe von Schlitzen 03 ist eine Mehrzahl austretender Vorsprünge 04 gezeigt, die Teil eines Falzmessers sind. Das Falzmesser ist an einem sogenannten Spider 06 befestigt. Dieser Spider 06, der in der Fig. 1 nur teilweise zu sehen ist, ist eine im Innern des Falzzylinders 01 um eine zu dessen Achse exzentrische Welle 09 rotierende Struktur mit zwei Armen 07, von denen jeder ein um eine zur Welle 09 parallele Achse rotierendes, kammähnliches Falzmesser trägt.On the body of in Fig. 1 shown folding cylinder 01 are three groups of flexible bands 02 each arranged at an angular distance of 120 ° in the circumferential direction of which two in the Fig. 1 you can see. Each of these groups is associated with a parallel to the axis of the folding cylinder 01 slidable bar whose function will be explained in more detail. The bands 02 define between each a plurality of slots 03. At the in the Fig. 1 At the top of the group of slots 03, there are shown a plurality of exiting protrusions 04 forming part of a folding blade. The folding blade is attached to a so-called spider 06. This Spider 06, in the Fig. 1 is only partially visible, is in the interior of the folding cylinder 01 about a shaft eccentric to its axis 09 rotating structure with two arms 07, each of which carries a shaft parallel to the shaft 09 rotating, comb-like folding blade.

Die Bänder 02 sind jeweils an zwei Stellen 11; 12, z. B. zwei Längsenden 11; 12 am Körper des Falzzylinders 01 gehalten. Von diesen Längsenden 11; 12 ist jeweils eines, in der Fig. 1 mit 11 bezeichnet, am Körper des Falzzylinders 01 unbeweglich, dass andere Längsende 12 ist in Umfangsrichtung des Falzzylinders 01 verschiebbar. Die verschiebbare Aufhängung des Längsendes 12 eines der Bänder 02 ist in Fig. 2 in einer detaillierten auseinandergezogenen Darstellung gezeigt.The bands 02 are each in two places 11; 12, z. B. two longitudinal ends 11; 12 held on the body of the folding cylinder 01. Of these longitudinal ends 11; 12 is one each, in the Fig. 1 denoted by 11, immovable on the body of the folding cylinder 01, that other longitudinal end 12 is displaceable in the circumferential direction of the folding cylinder 01. The slidable suspension of the longitudinal end 12 of one of the bands 02 is in Fig. 2 shown in a detailed exploded view.

Das Band 02 läuft an seinem Längsende 12 in zwei Zungen 13 aus, die um einen zylindrischen Stift 14 geschlungen sind. Der Stift 14 ist vorgesehen, um zwischen zwei Klemmkörpern 16; 17 eingeklemmt zu werden. Ebenso ist es denkbar, dass der Stift 14 seitlich in eine Bohrung eingeschoben wird und mit Hilfe einer Schraube fixiert wird. Die Klemmkörper 16; 17 werden durch (nicht dargestellte) Nieten oder andere geeignete Mittel zu einer als Gleitstein bezeichneten Einheit verbunden. In dem Gleitstein ist der Stift 14 fest gehalten, das Längsende 12 des Bandes 02 ist in Bezug auf den Gleitstein schwenkbar.The band 02 terminates at its longitudinal end 12 in two tongues 13 which are wound around a cylindrical pin 14. The pin 14 is provided to between two clamping bodies 16; 17 to be pinched. It is also conceivable that the pin 14 is inserted laterally into a bore and is fixed by means of a screw. The clamp body 16; 17 are connected by rivets (not shown) or other suitable means to a unit called a sliding block. In the sliding block, the pin 14 is held firmly, the longitudinal end 12 of the band 02 is pivotable with respect to the sliding block.

Im unteren Klemmkörper 17 ist eine in Längsrichtung des Bandes 02 langgestreckte Ausfräsung oder Vertiefung 18 gebildet. Am Boden der Vertiefung 18 befindet sich ein ebenfalls in Längsrichtung des Bandes 02 langgestrecktes, durchgehendes Loch 19.In the lower clamping body 17 an elongated cutout or recess 18 in the longitudinal direction of the strip 02 is formed. At the bottom of the recess 18 is a likewise elongated in the longitudinal direction of the strip 02, through hole 19th

Ein Mittel 21, z. B. ein Stift 21 weist einen Gewindeschaft 22 auf, der vorgesehen ist, um durch das Loch 19 und eine in die Vertiefung 18 eingefügte, durchbohrte Platte 23 durchgesteckt und mit Hilfe einer Mutter 24 fest gezogen zu werden. Die Ausdehnung der Platte 23 in Längsrichtung des Bandes 02 ist geringfügig kleiner als die der Vertiefung 18, so dass der Stift 21, wenn er nicht fest gezogen ist, in Längsrichtung des Bandes 02 ein Stück weit verschiebbar ist.A means 21, z. B. a pin 21 has a threaded shank 22 which is provided to be inserted through the hole 19 and inserted into the recess 18, pierced plate 23 and pulled with the help of a nut 24 firmly. The extent of the plate 23 in the longitudinal direction of the belt 02 is slightly smaller than that of the recess 18, so that the pin 21, if it is not tightened, in the longitudinal direction of the belt 02 is a piece of sliding.

An den Gewindeschaft 22 des Stiftes 21 grenzt ein Flansch 26 an, der im fest gezogenen Zustand des Stiftes 21 gegen die Unterseite des Klemmkörpers 17 drückt. Unterhalb des Flansches 26 ist der Stift 21 durch einen Wellenabschnitt verlängert, an dem eine Rolle 27, zwischen dem Flansch 26 und einem Kopf 28 des Stifts 21 gehalten, frei drehbar ist.At the threaded shank 22 of the pin 21 is adjacent to a flange 26 which presses in the tightened state of the pin 21 against the underside of the clamping body 17. Below the flange 26, the pin 21 is extended by a shaft portion on which a roller 27, held between the flange 26 and a head 28 of the pin 21, is freely rotatable.

Der untere Abschnitt des Stiftes 21 mit der Rolle 27 greift in ein Mittel 29, z. B. einThe lower portion of the pin 21 with the roller 27 engages in a means 29, for. B. a

Langloch 29 ein als Leiste 31 ausgebildetes Stellelement 31, die am Körper des Falzzylinders 01 schienengeführt in axialer Richtung, dargestellt durch den Doppelpfeil A, verschiebbar ist. Neben der verschiebbaren Leiste 31 erstreckt sich eine am Körper des Falzzylinders 01 ortsfeste, starre Strebe 32. Diese trägt an ihrer in der Fig. 2 oben liegenden Außenseite in regelmäßigen Abständen kurze Führungsschienen 33, die sich Umfangsrichtung des Falzzylinders 01 erstrecken und jeweils zu zweit einen Gleitstein in der Umfangsrichtung verschiebbar führen. Mit Hilfe des Stiftes 21 und der Führungsschienen 33 wird so eine Stellbewegung der Leiste 31 in axialer Richtung in eine Bewegung jedes Gleitsteines in Umfangsrichtung und damit in eine Umfangsvergrößerung oder-verkleinerung des Falzzylinders 01 umgesetzt.Slot 29 a trained as a bar 31 control element 31, which is rail-guided on the body of the folding cylinder 01 in the axial direction, shown by the double arrow A, is displaceable. In addition to the displaceable strip 31 extends to the body of the folding cylinder 01 stationary, rigid strut 32. This contributes to their in the Fig. 2 overhead outer side at regular intervals short guide rails 33 which extend in the circumferential direction of the folding cylinder 01 and each guide a sliding block sliding in the circumferential direction. With the help of the pin 21 and the guide rails 33 so an adjusting movement of the bar 31 in the axial direction is converted into a movement of each sliding block in the circumferential direction and thus in an enlargement or enlargement of the folding cylinder 01.

Die Mittel 21; 29 zum Umsetzen der axialen Verschiebung der Leiste 31 in eine Bewegung der ersten Stelle 12 der Bänder 02 in Umfangsrichtung umfasst jeweils ein schräg zur Axialrichtung und zur Umfangsrichtung orientiertes Langloch 29, das an einem der Bänder 02 gebildet ist, und einen mit der Leiste 31 verbundenen, in das Langloch 29 eingreifenden Stift 21.The means 21; 29 for converting the axial displacement of the strip 31 in a movement of the first point 12 of the bands 02 in the circumferential direction each comprises an obliquely oriented to the axial direction and the circumferential direction slot 29 formed on one of the bands 02, and one connected to the strip 31 , in the slot 29 engaging pin 21st

Fig. 3 zeigt eine schematische Darstellung eines Mechanismus zum Steuern der Position der jeder Gruppe von Bändern 02 zugeordneten Leiste 31. Eine Feder 34 übt auf die Leiste 31 eine in der Darstellung der Fig. 3 nach rechts gerichtete Kraft aus, die einen Kopfabschnitt der Leiste 31 gegen einen Anschlagring 37 gedrückt hält, der an einer Seitengestellplatte 36 des Falzapparates konzentrisch zum Falzzylinder 01 aber nicht mit diesem drehbar montiert ist. Des weiteren ist vorstellbar, dass auf die Feder 34 verzichtet wird, da die Spannung von Band 02 mittels der Schräge von Langloch 29 eine ausreichende axiale Kraft erzeugt. Fig. 3 shows a schematic representation of a mechanism for controlling the position of each group of strips 02 associated strip 31. A spring 34 exerts on the strip 31 in the representation of Fig. 3 rightward force holding a head portion of the strip 31 pressed against a stop ring 37 which is mounted on a side frame plate 36 of the folder concentric with the folding cylinder 01 but not rotatably mounted therewith. Furthermore, it is conceivable that the spring 34 is dispensed with, since the tension of band 02 by means of the bevel of slot 29 produces sufficient axial force.

An dem Kopfabschnitt ist ein Rad 38 drehbar gehalten, das bei einer Drehbewegung des Falzzylinders 01 auf der Oberfläche des Anschlagrings 37 abrollt. Da diese Oberfläche exakt senkrecht zur Achse des Falzzylinders 01 orientiert ist, bewirkt die Drehbewegung des Falzzylinders 01 keine axiale Verschiebung der Leiste 31. Eine solche Verschiebung kommt nur zustande, wenn der Anschlagring 37 als ganzes parallel zur Achse des Falzzylinders 01 verschoben wird. Eine solche Verschiebung des Anschlagrings 37 bewirkt jeweils identische Verschiebungen der Leisten 31 aller Gruppen von Bändern 02 und damit gleiche Änderungen der Krümmung an den Bändern 02 aller Gruppen.At the head portion, a wheel 38 is rotatably supported, which rolls on a rotational movement of the folding cylinder 01 on the surface of the stop ring 37. Since this surface is oriented exactly perpendicular to the axis of the folding cylinder 01, the rotational movement causes the folding cylinder 01 no axial displacement of the bar 31. Such a shift occurs only when the stop ring 37 is moved as a whole parallel to the axis of the folding cylinder 01. Such a displacement of the stop ring 37 causes identical shifts of the strips 31 of all groups of bands 02 and thus the same changes in the curvature of the bands 02 of all groups.

Zum Antreiben der Verschiebung des Anschlagrings 37 können diverse Mechanismen eingesetzt werden. Der in Fig. 3 exemplarisch dargestellte Mechanismus umfasst eine Mehrzahl von Gewindespindeln 42, von denen nur eine in der Fig. 3 gezeigt ist. Ein gewindefreier Abschnitt der Gewindespindeln 42 ist in der Seitengestellplatte 36 drehbar und axial nicht verschiebbar gelagert. Ein Gewindeabschnitt jeder Gewindespindel 42 ist im Eingriff mit einer Gewindebohrung 43 des Anschlagrings 37. Die Gewindespindeln 42 sind über einen Zahnriemen 44 gekoppelt, der mit an jeder Gewindespindel 42 befestigten Zahnrädern 46 in Eingriff ist. Da die Achsen der Gewindespindeln 42 ortsfest sind, kann ihre Drehbewegung in einfacher Weise wie angezeigt durch eine Kurbel 47 oder einen Stellmotor angetrieben werden, die/der unmittelbar an einer der Gewindespindeln 42 angreift.To drive the displacement of the stop ring 37, various mechanisms can be used. The in Fig. 3 exemplified mechanism includes a plurality of threaded spindles 42, of which only one in the Fig. 3 is shown. A thread-free portion of the threaded spindles 42 is rotatably mounted in the side frame plate 36 and axially non-displaceable. A threaded portion of each threaded spindle 42 is engaged with a threaded bore 43 of the stopper ring 37. The threaded spindles 42 are coupled via a toothed belt 44 which engages with gears 46 mounted on each threaded spindle 42. Since the axes of the threaded spindles 42 are stationary, their rotational movement in a simple manner as indicated by a crank 47 or a servomotor can be driven, the / directly on one of the threaded spindles 42 attacks.
