Description

Die vorliegende Erfindung betrifft Auslageeinrichtungen in dem Falzapparat einer Rotationsdruckmaschine.The present invention relates to delivery devices in the folder of a rotary printing press.

Aus dem Stand der Technik (DE-PS 38 17 804) ist eine Falzapparatauslage bei mehrstromiger Produktion bekannt. Bei dieser Einrichtung werden mehrere parallel betreibbare Schaufelradabschnitte, die seitlich aneinander anschließen, unabhängig voneinander angetrieben. Zwischen den Schaufelradabschnitten ist mindestens eine Führungsscheibe vorgesehen. Die äußeren Seitenscheiben beiderseits der Schaufelradabschnitte können über eine Zahnstange auf einer Welle in axialer Richtung verschoben werden. Die an den Verbindungsstellen der beiden Wellenenden angeordneten Führungsscheiben können über Stellspindeln um einen geringen Wegabschnitt in axialer Richtung bewegt werden.From the prior art (DE-PS 38 17 804) a folder delivery in multi-stream production is known. In this device, a plurality of paddle wheel sections which can be operated in parallel and which laterally adjoin one another are driven independently of one another. At least one guide disk is provided between the impeller sections. The outer side disks on both sides of the paddle wheel sections can be moved in the axial direction via a toothed rack on a shaft. The guide disks arranged at the connection points of the two shaft ends can be moved a small distance in the axial direction via adjusting spindles.

Es ist ein Nachteil bei dieser Falzapparatauslage, daß der Falzapparat zur Verstellung der Schaufelradabschnitte angehalten werden muß. Das Lösen und Arretieren der einzelnen Schaufelradkomponenten macht Ein- und Ausbauarbeiten in großem Umfang erforderlich, die viel Zeit in Anspruch nehmen. Bei einem Auftragswechsel geht viel Zeit für das Umrüsten verloren.A disadvantage of this folder delivery is that the folder must be stopped to adjust the paddle wheel sections. The loosening and locking of the individual paddle wheel components requires large-scale installation and removal work, which take a lot of time. When changing jobs, a lot of time is lost for the changeover.

Aus der DE-PS 31 13 399 ist eine Ausrichtvorrichtung für die Kanten eines aus Falzprodukten bestehenden Schuppenstroms bekannt.From DE-PS 31 13 399 an alignment device for the edges of a shingled stream consisting of folded products is known.

Auf Rollen umlaufende Transportbänder, die eine Rütteleinrichtung passieren, können über eine mindestens ein Gelenk aufweisende Schere in axialer Richtung bewegt werden.Conveyor belts rotating on rollers that pass through a vibrating device can be moved in the axial direction using scissors that have at least one joint.

Mit dieser Einrichtung können jedoch nur umlaufende Transportbänder verstellt werden, auf denen bereits fertig gefalzte Falzprodukte ausgelegt werden.With this device, however, only circulating conveyor belts can be adjusted, on which already folded folded products are laid out.

DE 40 15 217 A1 offenbart eine Auslegevorrichtung mit Falteinrichtung für Druckmaschinen. Eine Auslegevorrichtung zur Verwendung mit einer Falzeinrichtung einer Druckmaschine umfaßt eine Anzahl von Auslegerädern auf einer Welle, die in zwei Rahmen drehbar gelagert ist. Eine Verschiebe- und Antriebseinheit dient zum Verschieben der Auslegeräder in Axialrichtung auf der Welle. Verbindungseinrichtungen verbinden die Auslegeräder für eine gemeinsame Drehung mit der Welle und mit der Verschiebe- und Antriebseinrichtung. Die Auslegeräder können daher an Druckereierzeugnisse mit unterschiedlicher Breite angepaßt werden.DE 40 15 217 A1 discloses a delivery device with a folding device for printing presses. A delivery device for use with a folding device of a printing press comprises a number of delivery wheels on a shaft which is rotatably mounted in two frames. A displacement and drive unit is used to move the delivery wheels in the axial direction on the shaft. Connecting devices connect the delivery wheels for a common rotation with the shaft and with the displacement and drive device. The delivery wheels can therefore be adapted to printed products with different widths.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die Falzproduktauslage in dem Falzapparat einer Rotationsdruckmaschine dahingehend zu verbessern, daß während des Betriebs des Falzapparats eine gleichzeitige Anpassung der Falzproduktauslageeinrichtungen an das Falzproduktformat erfolgt. Durch die Voreinstellbarkeit des Produktflusses kann eine Automatisierung des Falzapparats erreicht und somit Einrichtezeit eingespart werden.Based on this prior art, the invention has for its object to improve the folded product delivery in the folder of a rotary printing press to the effect that a simultaneous adaptation of the folded product delivery devices to the folded product format takes place during the operation of the folder. Due to the fact that the product flow can be preset, automation of the folder can be achieved, thus saving setup time.

Erfindungsgemäß wird die Aufgabe durch die Merkmale der Patentansprüche 1 und 18 gelöst.According to the invention the object is solved by the features of claims 1 and 18.

Der Vorteil nach vorliegender Erfindung liegt darin, daß nunmehr eine automatische Einstellung des Falztrichters zusammen mit den Schaufelradauslagen möglich ist. Dies spart Einrichtezeit und verringert besonders den Zeitaufwand zur Anpassung der Auslageeinrichtungen an neue Formate auf ein Minimum. Somit läßt sich bei einem Falzapparat mit vier Schaufelrädern eine drastische Reduzierung der Rüstzeiten erzielen. Die automatische Formatanpassung ermöglicht zudem, daß in der Startphase des Druckens die seitlichen Falzproduktführungen bei noch unregelmäßiger Auslage der Falzexemplare abgestellt werden können, um einen Papierstau im Falzapparat zu vermeiden. Der Bediener kann sich also gerade während der Anlaufphase anderen Überwachungstätigkeiten widmen.The advantage of the present invention is that it is now possible to automatically adjust the former together with the paddle wheel extensions. This saves set-up time and in particular reduces the time required to adapt the delivery equipment to new formats to a minimum. This means a drastic reduction in makeready times for a folder with four paddle wheels achieve. The automatic format adjustment also enables that the side fold product guides in the initial phase of printing while the delivery is still irregular Folded copies can be parked to avoid paper jams in the folder. The operator can therefore devote himself to other monitoring activities during the start-up phase.

Eine günstige Ausführung der Erfindung sieht Schaufelradscheiben, Transport- und Auslagebänder vor, wobei die Schaufelradscheiben auf einer Welle verschiebbar gelagert sind und durch Arme bewegt werden, die an Gleitstücken befestigt sind. Vorteilhaft an dieser Ausführung ist die separate Verschiebung jeder einzelnen Schaufelradscheibe bei automatischer Formatanpassung während des Betriebs.A favorable embodiment of the invention provides bucket wheel disks, transport and delivery belts, the bucket wheel disks being slidably mounted on a shaft and being moved by arms which are fastened to sliders. The advantage of this version is the separate displacement of each individual paddlewheel disc with automatic format adjustment during operation.

Weiterhin sieht eine vorteilhafte Ausbildung des Erfindungsgegenstandes vor, daß an den Schaufelradscheiben Lager angebracht und darauf Ringe gelagert sind, auf denen die Arme befestigt sind. Der Vorteil dieser Ausbildung liegt darin, daß das Gewicht der Arme auf den Ringen liegt und dadurch ein Verkanten der Schaufelradscheiben beim Verschieben auf der Welle dank der Lager verhindert wird. Somit entsteht kein Verschleiß zwischen den bewegten Teilen. Die exakte Lagerung der Arme an den Schaufelradscheiben ermöglicht ferner eine genaue Führung der Schaufelradscheiben auf der Welle.Furthermore, an advantageous embodiment of the subject matter of the invention provides that bearings are attached to the paddle wheel disks and rings are mounted thereon on which the arms are attached. The advantage of this design is that the weight of the arms lies on the rings and this prevents the bucket wheel disks from tilting when moving on the shaft thanks to the bearings. There is no wear between the moving parts. The exact mounting of the arms on the paddlewheel disks also enables the paddlewheel disks to be guided precisely on the shaft.

Nach einer weiteren günstigen Ausgestaltung der Erfindung werden auf einer Achse verschiebbare Gleitstücke von Spindelköpfen bewegt. Diese Ausgestaltung hat den Vorzug, daß auf kostspielige Gleitschienen verzichtet werden kann und eine preiswerte, zuverlässige Konstruktion möglich geworden ist.According to a further advantageous embodiment of the invention, sliding parts of spindle heads that can be moved on an axis are moved. This configuration has the advantage that it is possible to dispense with expensive slide rails and an inexpensive, reliable construction has become possible.

In einer weiteren günstigen Ausgestaltung der Erfindung ist vorgesehen, daß in Seitenwände des Falzapparats Buchsen und darin Verstellspindeln gelagert sind, die durch einen Elektromotor gleichzeitig angetrieben werden. Der Vorteil dieser Ausführung liegt darin, daß beispielsweise vier bewegbare Schaufelradscheiben von einem Verstellaggregat bewegt werden können. Dadurch ist eine synchrone Verstellung der Auslageeinrichtungen erreicht.In a further advantageous embodiment of the invention it is provided that bushings and adjusting spindles are mounted in the side walls of the folder and are driven simultaneously by an electric motor. The advantage This design is such that four movable paddlewheel disks can be moved by an adjusting unit. A synchronous adjustment of the delivery devices is thereby achieved.

Eine weitere günstige Ausführung der Erfindung umfaßt eine Welle mit darauf verschiebbaren Gleitstücken; Spindelköpfe, welche die Gleitstücke bewegen; Verstellspindeln, auf welchen im Bereich der Spindelköpfe Hülsen befestigt sind, die abwechselnd ein- oder mehrgängige Gewindeabschnitte aufweisen; oder es sind Gewinde mit unterschiedlicher Gewindesteigung in die Verstellspindeln gefräst. Vorteilhaft dabei ist, daß die Wahl der Gewindegänge einen gewissen proportionalen Stellweg der Schaufelradscheiben sowie den einzuhaltenden gleichen Abstand zwischen den einzelnen Schaufelradscheiben während des Verstellvorgangs bestimmt.Another cheap embodiment of the invention comprises a shaft with sliders slidable thereon; Spindle heads that move the sliders; Adjustment spindles, on which sleeves are fastened in the area of the spindle heads, which have alternating single or multiple thread sections; or threads with different thread pitches are milled into the adjustment spindles. It is advantageous that the choice of threads determines a certain proportional travel of the paddlewheel disks and the same distance to be maintained between the individual paddlewheel disks during the adjustment process.

Eine weitere günstige Ausführung der Erfindung sieht vor, daß für die auf Achsen verschiebbaren Gleitstücke verschiebbare Anschläge auf diesen Achsen befestigt sind. Der Vorteil hierbei ist eine Begrenzung des Stellweges mit einfachen Mitteln.A further advantageous embodiment of the invention provides that slidable stops are fastened on these axes for the sliding pieces which can be moved on axes. The advantage here is a limitation of the travel range with simple means.

Eine alternative Ausgestaltung der Erfindung umfaßt eine röhrenförmige Welle, auf welcher verschiebbar angeordnete Schaufelradscheiben angebracht sind; mit den Schaufelradscheiben verbundene Spindelköpfe; in der röhrenförmigen Welle gelagerte, mit den Spindelköpfen zusammenwirkende Verstellspindeln; ein in der röhrenförmigen Welle angebrachter elektrischer Motor, und ein Ritzel und Zahnräder, über welche der elektrische Motor die Verstellspindeln bewegt. Diese alternative Ausführung erlaubt eine kostengünstige und raumsparende Konstruktion, da die Verstellmechanismen in der röhrenförmigen Welle untergebracht werden können.An alternative embodiment of the invention comprises a tubular shaft on which displaceably arranged paddle wheel disks are attached; spindle heads connected to the impeller disks; adjusting spindles mounted in the tubular shaft and interacting with the spindle heads; an electric motor mounted in the tubular shaft, and a pinion and gearwheels via which the electric motor moves the adjusting spindles. This alternative design allows for a cost-effective and space-saving design, since the adjustment mechanisms can be accommodated in the tubular shaft.

Nach einer vorteilhaften Ausführung ist eine seitliche Falzproduktführung vorgesehen, ein mit der seitlichen Falzproduktführung verbundener Arm, ein mit dem Arm verbundenes Gleitstück und eine Einrichtung zum pneumatischen Aktivieren des Gleitstücks oder einer mit dem Gleitstück verbundenen Verstellspindel, und ein mit der Verstellspindel verbundenes Handrad zum manuellen Aktivieren des Gleitstücks. Diese Ausgestaltung ermöglicht es, die seitliche Falzproduktführung beim Anlauf des Falzapparats zurückzustellen, um eine Beeinträchtigung des noch unregelmäßigen Produktstroms zu vermeiden und somit mögliche Papierstaus im Falzapparat zu verhindern. Mit diesem erfinderischen Merkmal ist ein schneller Anlauf der Produktion gewährleistet.According to an advantageous embodiment, a lateral fold product guide is provided, an arm connected to the lateral fold product guide, a slide piece connected to the arm and a device for pneumatically activating the slide piece or an adjusting spindle connected to the slide piece, and a handwheel connected to the adjusting spindle for manual activation of the slider. This configuration makes it possible to reset the lateral folding product guide when the folding device starts up in order to avoid impairment of the still irregular product flow and thus to prevent possible paper jams in the folding device. With this inventive feature, a quick start of production is guaranteed.

Eine weitere vorteilhafte Ausführung der Erfindung sieht vor, daß Transportbänder, die bis in die Zwischenräume zwischen die Schaufelradscheiben geführt sind, bei der Formatanpassung der Schaufelradscheiben gleichzeitig automatisch mit verstellt werden. Diese Ausführung ermöglicht es, bei variablem Format der Falzprodukte die Auslageeinrichtungen unmittelbar dem Format anzupassen und optimale Transport- bzw. Auslagebedingungen für die Falzexemplare zu schaffen.A further advantageous embodiment of the invention provides that conveyor belts which are guided into the spaces between the paddlewheel disks are simultaneously automatically adjusted when the paddlewheel disks are adapted to the format. This design makes it possible to adapt the delivery devices to the format in the case of a variable format of the folding products and to create optimal transport and delivery conditions for the folding copies.

In einer weiteren günstigen Ausgestaltung des Erfindungsgegenstandes ist vorgesehen, daß die Verstelleinheiten für die Schaufelradscheiben und die seitliche Falzproduktführung in Modulbauweise ausgeführt sind. Der Vorteil bei dieser Konstruktion ist die platzsparende Anordnung der Verstelleinheiten, die schnelle Austauschbarkeit und die kostengünstige Produktion derselben.In a further advantageous embodiment of the subject matter of the invention, it is provided that the adjusting units for the paddle wheel disks and the lateral folding product guide are designed in a modular design. The advantage of this design is the space-saving arrangement of the adjustment units, the quick interchangeability and the cost-effective production of the same.

Außerdem ist eine Ausführung vorgesehen, bei der an Armen, welche die Schaufelradscheiben bewegen, Abstreifzungen vorgesehen sind. Diese gewährleisten eine kontinuierliche Falzproduktfolge auf nachgeordneten Transportbändern.In addition, an embodiment is provided in which scraper tongues are provided on arms which move the paddle wheel disks. These ensure a continuous fold product sequence on downstream conveyor belts.

Letztlich ist eine Ausgestaltung der Erfindung vorgesehen, welche in einem Falzapparat einer Rotationsdruckmaschine ein Auslagesystem umfaßt mit einer freitragenden Welle und axial bewegbaren, auf der freitragenden Welle angebrachten Elementen, und wobei die Auslageeinrichtungen mit auf axial bewegbaren Gleithülsen befestigten Schaufelradscheiben, mit einer Vorrichtung zum parallelen Betrieb der Auslageeinrichtungen, mit einer Vorrichtung zum Antrieb der Auslageeinrichtungen unabhängig voneinander, und mit Schubstangenantrieben zum Verstellen der Auslageeinrichtungen unabhängig von einander während des Maschinenbetriebs und bei Maschinenstillstand versehen sind.Ultimately, an embodiment of the invention is provided which, in a folder of a rotary printing press, comprises a delivery system with a cantilever shaft and axially movable elements mounted on the cantilever shaft, and the delivery devices with paddle wheel disks fastened on axially movable sliding sleeves, with a device for parallel operation of the delivery devices are provided with a device for driving the delivery devices independently of one another, and with push rod drives for adjusting the delivery devices independently of one another during machine operation and when the machine is at a standstill.

Die Vorteile dieser Ausführung liegen darin, daß auf eine Abstützung der die Auslageeinrichtungen tragenden Welle verzichtet werden kann und dadurch eine bessere Zugänglichkeit gewährleistet ist.

In Fig. 1 ist eine Seitenansicht einer Schaufelradscheibe mit Transportbändern und Verstelleinheiten für eine seitliche Falzproduktführung und der Schaufelradscheiben in Modulbauweise gezeigt.1 shows a side view of a bucket wheel disk with conveyor belts and adjustment units for lateral folding product guidance and the bucket wheel disks in a modular design.

Die Auslageeinrichtungen 3 umfassen Bänder 2, die auf Bandrollen 1 umlaufen. Die Bänder 2 führen Falzexemplare zu den Schaufelradscheiben 6, welche nebeneinander auf der Welle 4 angeordnet sind. Die Schaufelradscheiben 6 sind so ausgebildet, daß sie Taschen 7 formen, in welche durch die Bänder 2 Falzprodukte befördert werden. Ein jeweiliger Arm 8 ist mit einer jeweiligen Schaufelradscheibe 6 verbunden.The delivery devices 3 comprise belts 2 which run on belt rolls 1. The bands 2 lead folded copies to the paddle wheel disks 6, which are arranged side by side on the shaft 4. The paddle wheel disks 6 are designed such that they form pockets 7, into which 2 folded products are conveyed by the belts. A respective arm 8 is connected to a respective paddle wheel disk 6.

Im rechten Teil der Fig. 1 sind Verstelleinheiten 5 und 9 in Modulbauweise übereinander angeordnet. Im linken Teil der Fig. 1 ist die Verstelleinheit 10 zu erkennen, mittels welcher die seitliche Falzproduktführung 11 automatisch positionierbar ist. An den Schaufelradscheiben 6 sind Abstreifzungen 36 vorgesehen, die an die Arme 8 angeschraubt werden können.In the right part of FIG. 1, adjusting units 5 and 9 are arranged one above the other in a modular design. In the left part of FIG. 1, the adjustment unit 10 can be seen, by means of which the lateral folding product guide 11 can be automatically positioned. Scraper tongues 36 are provided on the paddle wheel disks 6 and can be screwed onto the arms 8.

Fig. 2 zeigt die Draufsicht von Schaufelradscheiben bei kleinstem Produktformat und abgestellter seitlicher Falzproduktführung 11. Die in der Mitte der Fig. 1 gezeigte Welle 4 weist vier verstellbare Schaufelradscheiben 6 auf, welche über die Arme 8 mit Gleitstücken 12 verbunden sind. Die Gleitstücke 12 sind auf einer Achse 13 angeordnet und auf dieser in beide Richtungen verschiebbar. Zur Begrenzung der Verschiebung in axialer Richtung dienen Anschläge 14, die lösbar auf der Achse 13 befestigt sind. Die Gleitstücke 12 weisen Spindelköpfe 14a auf, in denen sich Verstellspindeln 15 drehen können. Die Verstellspindeln 15 sind an ihren Enden mit Buchsen 16 verbunden, die in den Seitenwänden 17 und der Mittelwand 18 gelagert sind. Ein Elektromotor 19 betätigt über ein Getriebe, bestehend aus einer Schnecke 20 und einem Schneckenrad 21, die Verstellspindeln 15.FIG. 2 shows the top view of paddle wheel disks in the smallest product format and with the folded product guide 11 on the side. The one shown in the middle of FIG. 1 Shaft 4 has four adjustable paddle wheel disks 6, which are connected to sliders 12 via arms 8. The sliders 12 are arranged on an axis 13 and slidable in both directions on this. To limit the displacement in the axial direction, stops 14 are used, which are releasably attached to the axis 13. The sliders 12 have spindle heads 14a, in which adjusting spindles 15 can rotate. The adjusting spindles 15 are connected at their ends to bushings 16 which are mounted in the side walls 17 and the middle wall 18. An electric motor 19 actuates the adjusting spindles 15 via a gear consisting of a worm 20 and a worm wheel 21.

Im Bereich der Spindelköpfe 14a weisen die Verstellspindeln 15 Gewindeabschnitte 23, 24, 25 und 26 auf. Diese Gewindeabschnitte sind von unterschiedlicher Länge oder haben unterschiedliche Gewindesteigungen, je nach der zu bewegenden Schaufelradscheibe 6. Die Gewinde können in den Verstellspindeln 15 eingefräst sein oder als ein- oder mehrgängige Gewinde ausgebildet sein. Die synchrone Verstellung der Schaufelradscheiben 6, unter Beibehaltung eines gleichmäßigen Abstandes der Schaufelradscheiben 6 voneinander, wird durch unterschiedliche Gewindeausführungen erreicht. Die mit "FAN 5" bezeichnete Schaufelradscheibe 6, liegt bei der Verstellung von minimaler auf maximale Stellpostion den größten Weg zurück. Dies wird durch den Gewindeabschnitt 26 (ausgeführt mit einer großen Steigung) erreicht. Die mit "FAN 4" bezeichnete bewegliche Schaufelradscheibe 6 legt bei der Verstellung den drittlängsten Weg zurück. Demzufolge ist der Gewindeabschnitt 25 etwas kürzer ausgebildet als der Gewindeabschnitt 26. Dort kann ein Gewinde mit einer etwas flacheren Steigung verwendet werden. Bei "FAN 3" und "FAN 2" verhält es sich entsprechend, wobei der kürzeste Gewindeabschnitt 23 für "FAN 2" vorgesehen ist, da diese Schaufelradscheibe 6 bei der Verstellung den kürzesten Weg zurücklegt. Eine Schaufelradscheibe 6a ist auf der Welle 4 ortsfest gelagert. Werden die Verstellspindeln 15 über den Elektromotor 19 angetrieben, so wird durch deren gleichzeitigen Antrieb und den durch die Länge der Gewindeabschnitte 23, 24, 25 und 26 vorgegebenen Verstellweg eine Formatanpassung erreicht. Eine Nachjustierung ist nicht erforderlich, da die Stellpositionen mit großer Genauigkeit erreicht werden.In the area of the spindle heads 14a, the adjusting spindles 15 have threaded sections 23, 24, 25 and 26. These threaded sections are of different lengths or have different thread pitches, depending on the paddle wheel disc 6 to be moved. The threads can be milled into the adjusting spindles 15 or be designed as single or multiple threads. The synchronous adjustment of the paddle wheel disks 6, while maintaining a uniform distance between the paddle wheel disks 6, is achieved by different thread designs. The paddle wheel disk 6, designated "FAN 5", is the longest way back in the adjustment from minimum to maximum positioning position. This is achieved by the threaded section 26 (carried out with a large pitch). The movable paddle wheel disk 6 labeled "FAN 4" covers the third longest path during the adjustment. Accordingly, the threaded portion 25 is somewhat shorter than the threaded portion 26. There, a thread with a somewhat flatter pitch can be used. The same applies to "FAN 3" and "FAN 2", the shortest threaded section 23 being provided for "FAN 2", since this Paddle wheel disc 6 covers the shortest path during the adjustment. A paddle wheel disk 6a is mounted on the shaft 4 in a stationary manner. If the adjustment spindles 15 are driven by the electric motor 19, a format adjustment is achieved by their simultaneous drive and the adjustment path predetermined by the length of the threaded sections 23, 24, 25 and 26. Readjustment is not necessary because the positioning positions are reached with great accuracy.

Anstelle von Gewindeabschnitten mit unterschiedlicher Steigung können auch Gewinde mit unterschiedlicher Gangzahl eingesetzt werden, wodurch die geforderte Bewegung der Schaufelradscheiben auch erreichbar ist. Die gleichzeitige automatische Verstellung der Schaufelradscheiben, zusammen mit der automatischen Einstellung des Falztrichters, erlaubt extrem kurze Einrichte- und Umstellzeiten während des Maschinenlaufs.Instead of threaded sections with different pitches, threads with different numbers of gears can also be used, as a result of which the required movement of the paddle wheel disks can also be achieved. The simultaneous automatic adjustment of the paddlewheel disks, together with the automatic adjustment of the former, allows extremely short setup and changeover times while the machine is running.

In Fig. 2 ist ferner eine Verstelleinheit 10 gezeigt, mit welcher die seitliche Falzproduktführung 11 an- und abgestellt werden kann. Ein Gleitstück 27, welches auf einer Achse 13 verschiebbar gelagert ist, bewegt über einen Arm 28 die seitliche Falzproduktführung 11. In dem Gleitstück 27 kann ein pneumatischer Zylinder 29 vorgesehen sein, mit welchem eine pneumatisches Abstellen der Falzproduktführung beim Anlauf der Druckmaschine möglich ist. Darüber hinaus kann durch ein Handrad 30, welches eine Feineinstellspindel 31 bewegt, die Falzproduktführung manuell aktiviert werden. Wie aus Fig. 1 hervorgeht, ist die Verstelleinheit 10 für das Verstellen der seitlichen Falzproduktführung 11 in Modulbauweise ausgeführt und kann somit für die Bedien- und für die Antriebsseite verwendet werden. Die der beweglichen Falzproduktführung 11 gegenüberliegende Falzproduktführung ist mit "FAN 5" verbunden und wird bei der Verstellung der Schaufelradscheibe 6 zusammen mit dieser bewegt.FIG. 2 also shows an adjustment unit 10 with which the lateral folding product guide 11 can be turned on and off. A slider 27, which is slidably mounted on an axis 13, moves the lateral folded product guide 11 via an arm 28. A pneumatic cylinder 29 can be provided in the slider 27, with which a pneumatic shutdown of the folded product guide is possible when the printing machine starts up. In addition, the folding product guidance can be activated manually by means of a handwheel 30, which moves a fine adjustment spindle 31. As can be seen from FIG. 1, the adjustment unit 10 is designed in a modular design for the adjustment of the side fold product guide 11 and can thus be used for the operator and for the drive side. The folded product guide opposite the movable folded product guide 11 is labeled "FAN 5" connected and is moved together with this when adjusting the paddle wheel disk 6.

Fig. 3 zeigt eine Draufsicht der auf das größte Format eingestellten Schaufelradscheiben mit angestellter seitlicher Falzproduktführung. Die Schaufelradscheiben 6 werden auf der Welle 4, die in Lagern 32, 33 gelagert ist, in ihre maximale Stellposition bewegt. Die seitliche Falzproduktführung 11 ist an das "FAN 1" angestellt. Die Gleitstücke 12 werden durch die Spindelköpfe 14a in die jeweilige Stellposition bewegt. Der Verstellweg, den das Gleitstück 12 zurückgelegt hat, ist an der Position, die der Spindelkopf 14a auf dem Gewindeabschnitt 26 eingenommen hat, zu erkennen. Zur Verminderung von Reibung und Vermeidung von Verkantung beim Verschieben der Schaufelradscheiben 6 sind die Arme 8 über Lager 34 auf Ringen 35 an den Schaufelradscheiben 6 gelagert. An den Armen 8 sind ferner Abstreifzungen 36 vorgesehen, welche die Falzprodukte aus den Taschen 7 herausführen. Auf der Welle 4 ist neben dem Lager 32 ein Antriebsrad 37 angeordnet, mit welchem die Welle 4 über einen Riementrieb angetrieben werden kann.3 shows a top view of the paddlewheel disks set to the largest format with the folded product guide on the side. The paddle wheel disks 6 are moved to their maximum position on the shaft 4, which is mounted in bearings 32, 33. The side folding product guide 11 is employed by the "FAN 1". The sliding pieces 12 are moved into the respective setting position by the spindle heads 14a. The adjustment path which the slide 12 has covered can be recognized from the position which the spindle head 14a has assumed on the threaded section 26. In order to reduce friction and avoid canting when moving the paddle wheel disks 6, the arms 8 are supported on the paddle wheel disks 6 via bearings 34 on rings 35. Scraper tongues 36 are also provided on the arms 8, which guide the folded products out of the pockets 7. A drive wheel 37 is arranged on the shaft 4 next to the bearing 32, with which the shaft 4 can be driven via a belt drive.

In Fig. 1 sind Bänder 2 gezeigt, deren Führungsrollen 1 bis an den Umfang der Schaufelradscheiben 6 herangeführt sind. Diese Bänder 2 können sowohl an der Falzprodukt-Zufuhrseite als auch an der Ausgabeseite bis in die Zwischenräume zwischen die einzelnen Schaufelradscheiben 6 hineingeführt werden. Bei der automatischen Formatanpassung sind diese Transportbänder entsprechend den verschiebbaren Schaufelradscheiben 6 bewegbar, um eine optimale Produktauslage zu erreichen.In Fig. 1 tapes 2 are shown, the guide rollers 1 are brought up to the circumference of the paddle wheel discs 6. These belts 2 can be fed into the spaces between the individual paddle wheel disks 6 both on the folded product supply side and on the output side. With the automatic format adjustment, these conveyor belts can be moved in accordance with the displaceable paddle wheel disks 6 in order to achieve an optimal product delivery.

In Fig. 4 ist eine Ausführung des Erfindungsgegenstandes dargestellt, bei der eine in einer Mittelwand 17 des Falzapparats gelagerte freitragende Welle 38 mit mehreren Schaufelradgleitstücken gezeigt ist. Die freitragende Welle 38 ist im Wellenlager 39 gelagert. An der Mittelwand 17 ist ein Widerlagergehäuse 40 angeflanscht, in welchem ein Ende der freitragenden Welle 38 über ein Widerlager 41 abstützt ist. Auf der freitragenden Welle 38 ist eine Wellenpaßfeder 42 vorgesehen, mit welcher die Rotation der Welle 38 auf eine axial verschiebbare Gleithülse 43 übertragen wird. An der Gleithülse 43 ist eine Schaufelradscheibe 6 befestigt. Die Gleithülse 43 ist über einen drehbar gelagerten Arm 44 mit einer Schubstange 45 verbunden. Die Schubstange 45 ist in der Mittelwand 17 durch eine Lagerung 46 bewegbar. Ein Schubstangenantrieb 47 dient zur Bewegung der Schubstange 45 in axialer Richtung. Auf der Gleithülse 43 ist eine Paßfeder 48 befestigt, durch welche die Drehung der freitragenden Welle 38 über die Gleithülse 43 auf eine Gleithülse 49 übertragen wird. Die Gleithülse 49 wird über einen Arm 50 und eine Schubstange 51 in gleicher Weise wie die Gleithülse 43 axial bewegt. Der Schubstangenantrieb für die Gleithülse 49 ist nicht dargestellt.4 shows an embodiment of the subject matter of the invention, in which a cantilevered shaft 38 mounted in a middle wall 17 of the folder is shown with a plurality of paddle wheel sliding pieces. The self-supporting Shaft 38 is supported in shaft bearing 39. An abutment housing 40 is flanged to the middle wall 17, in which one end of the self-supporting shaft 38 is supported via an abutment 41. A shaft key 42 is provided on the self-supporting shaft 38, with which the rotation of the shaft 38 is transmitted to an axially displaceable sliding sleeve 43. A paddle wheel disk 6 is attached to the sliding sleeve 43. The sliding sleeve 43 is connected to a push rod 45 via a rotatably mounted arm 44. The push rod 45 is movable in the middle wall 17 by a bearing 46. A push rod drive 47 serves to move the push rod 45 in the axial direction. A key 48 is fastened on the sliding sleeve 43, by means of which the rotation of the self-supporting shaft 38 is transmitted to a sliding sleeve 49 via the sliding sleeve 43. The sliding sleeve 49 is moved axially via an arm 50 and a push rod 51 in the same way as the sliding sleeve 43. The push rod drive for the sliding sleeve 49 is not shown.

Die Gleithülse 49 selbst weist eine Paßfeder 52 auf, die die Gleithülse 53 in Rotation versetzt und damit die Schaufelradscheibe 6 bewegt. Die Gleithülse 53 wird in gleicher Weise wie die beiden vorhergehend beschriebenen Gleithülsen über einen Arm 54 und eine Schubstange 55 bewegt. Somit können nebeneinander angeordnete Schaufelradscheiben durch Stellantriebe in der Mittelwand des Falzapparates verstellt werden.The sliding sleeve 49 itself has a feather key 52, which sets the sliding sleeve 53 in rotation and thus moves the paddle wheel disk 6. The sliding sleeve 53 is moved in the same way as the two sliding sleeves described above via an arm 54 and a push rod 55. Paddlewheel disks arranged next to one another can thus be adjusted by actuators in the central wall of the folder.

Figur 5 zeigt eine bauraumsparende Anordnung des Verstellmechanismus. Gemäß dieser Ausführungsvariante wird zwischen der Seitenwand 18 und der Mittelwand 17 eine röhrenförmige Welle 57 aufgenommen, die in Lagern 32 und 33 rotiert. In die röhrenförmige Welle 57 ist ein Elektromotor 19 eingebaut, der über ein Ritzel 58 und ein Zahnrad 59 eine erste Verstellspindel 15 antreibt. Durch Zahnräder 22 wird der Antrieb von der ersten auf eine zweite Verstellspindel 15 übertragen, die ebenfalls in der röhrenförmigen Welle 57 gelagert ist.
Analog zu den in Fig. 2 und 3 gezeigten Ausführungen, sind auf den Verstellspindeln 15 Gewindeabschnitte 23,24,25 und 26 vorgesehen, durch welche sich Spindelköpfe 14b seitlich bewegen und somit die Schaufelradscheiben 6 verschieben können. An den bewegbaren Schaufelradscheiben 6 sind Abstreifzungen 36 befestigt. Die Schaufelradscheibe 6a ist auf der röhrenförmigen Welle 57 fixiert und nicht verschiebbar. Durch unterschiedliche Gewindesteigungen der Gewindeabschnitte 23,24,25 und 26 können die Schaufelradscheiben 6 proportional seitwärts verschoben werden. Ferner kann der Beginn des jeweiligen Gewindeabschnitts auf den Antriebsspindeln 15 so gelegt werden, daß eine proportionale, dem zurückzulegenden Weg der jeweiligen Schaufelradscheibe 6 entsprechende Verschiebung erfolgen kann. Die Spindelköpfe 14b bewegen sich in parallel zur Rotationsachse verlaufenden Ausnehmungen der röhrenförmigen Welle 57, deren Antrieb über ein Antriebsrad 37 erfolgen kann. Die Stromversorgung des Elektromotors 19 erfolgt über einen elektrischen Drehkontakt 56.
Diese Ausführungsform ermöglicht eine raumsparende Unterbringung des Verstellmechanismus in der Welle, auf der die Schaufelradscheiben angeordnet sind. Es wird dadurch eine einfachere Verstellung der Abstreifzungen sowie eine kostengünstigere Konstruktion erreicht.Figure 5 shows a space-saving arrangement of the adjustment mechanism. According to this embodiment variant, a tubular shaft 57 is received between the side wall 18 and the middle wall 17 and rotates in bearings 32 and 33. An electric motor 19 is installed in the tubular shaft 57 and drives a first adjusting spindle 15 via a pinion 58 and a gear wheel 59. By Gear wheels 22 transmit the drive from the first to a second adjusting spindle 15, which is also mounted in the tubular shaft 57.
Analogous to the embodiments shown in FIGS. 2 and 3, 15 threaded sections 23, 24, 25 and 26 are provided on the adjusting spindles, through which threaded heads 14b can move laterally and thus can move the paddle wheel disks 6. Scraper tongues 36 are attached to the movable paddle wheel disks 6. The paddle wheel disc 6a is fixed on the tubular shaft 57 and is not displaceable. The paddlewheel disks 6 can be displaced proportionally sideways by different thread pitches of the threaded sections 23, 24, 25 and 26. Furthermore, the beginning of the respective threaded section can be placed on the drive spindles 15 in such a way that a proportional displacement corresponding to the travel of the respective paddle wheel disk 6 can take place. The spindle heads 14b move in recesses of the tubular shaft 57 which run parallel to the axis of rotation and can be driven via a drive wheel 37. The electric motor 19 is supplied with power via an electrical rotary contact 56.
This embodiment enables space-saving accommodation of the adjustment mechanism in the shaft on which the paddle wheel disks are arranged. This results in a simpler adjustment of the scraper tongues and a more cost-effective construction.
