Description

Die Erfindung betrifft eine Längsfalzvorrichtung mit mindestens einem Falztrichter gemäß dem Oberbegriff des Patentanspruches 1. Eine solche Längsfalzvorrichtung ist Zum Beispiel aus der FR-A-1554364 bekannt.The invention relates to a longitudinal folding device with at least one former, according to the preamble of claim 1. Such a longitudinal folding device is known, for example, from FR-A-1554364.

Falztrichter werden in Falzapparaten bekanntlich zur Erzeugung von Längsfalzen in einer darüber hinweggezogenen Materialbahn benutzt. Bestimmte Produktarten, die im Zusammmenwirken mit nachgeschalteten Quer-oder Längsfalzeinrichtungen eines Falzapparates gefertigt werden sollen, erfordern eine Verschiebung des Falztrichters oder bei mehreren eines der Falztrichter in Längsrichtung der ankommenden Materialbahn.Folding formers are known to be used in folders for the production of longitudinal folds in a material web drawn over them. Certain types of products that are to be produced in cooperation with downstream transverse or longitudinal folding devices of a folding apparatus require the former or, in the case of several, one of the former, to be displaced in the longitudinal direction of the incoming material web.

Bei den von Druckmaschinen des Typs ROTOMAN der M.A.N. - ROLAND Druckmaschinen Aktiengesellschaft, Offenbach, bekannten Falzapparaten wird, um den gewünschten Versatz der Trichternase zu erreichen, der Falztrichter horizontal verschoben. Dabei muß die dem Falztrichter vorgeschaltete Trichtereinlaufwalze um den gleichen Betrag horizontal mitverschoben werden, wobei sich außerdem eine Änderung des Umschlingungswinkels und damit der Zugverhältnisse ergibt. Da die Trichtereinlaufwalze in den Antriebsstrang eingeschaltet ist, läßt sich ihre Verschiebung nur mit erheblichem konstruktiven Aufwand bewerkstelligen. Bei den bisher üblichen, horizontal wirkenden Vorrichtungen ist außerdem bei einer Verschiebung eines von mehreren Falztrichtern für diesen eine eigene Trichtereinlaufwalze notwendig.In the folders known from ROTOMAN printing presses from MAN - ROLAND Druckmaschinen Aktiengesellschaft, Offenbach, the folder is horizontally displaced in order to achieve the desired offset of the former nose. In this case, the hopper inlet roller upstream of the folding former must be displaced horizontally by the same amount, which also results in a change in the wrap angle and thus in the draft conditions. Since the hopper inlet roller is switched on in the drive train, its displacement can only be accomplished with considerable design effort. In the hitherto usual, horizontally acting devices, a separate former infeed roller is also necessary when one of the several former is shifted.

Aufgabe der Erfindung ist es, bei einer gattungsgemäßen Längsfalzvorrichtung eine Verschiebung eines Falztrichters mit einfachen konstruktiven Mitteln zu erreichen.The object of the invention is to achieve a displacement of a former with simple constructional means in a generic longitudinal folding device.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Falztrichter in Richtung der Trichterneigung verstellbar angeordnet ist.This object is achieved in that the folding former is arranged to be adjustable in the direction of the former inclination.

Hierdurch ergibt sich der Vorteil, daß bei einer Trichterverschiebung der Winkel, mit dem die Materialbahn die dem Falztrichter vorgeschaltete Trichtereinlaufwalze umschlingt, konstant bleibt.
Dadurch, daß keine angetriebenen Teile zu bewegen sind, ergibt sich ein erheblich vereinfachter konstruktiver Aufbau der Längsfalzvorrichtung. Bei mehreren nebeneinander angeordneten Falztrichtern genügt außerdem eine einzige durchgehende Trichtereinlaufwalze.This results in the advantage that the angle at which the material web wraps around the hopper inlet roller upstream of the folding former remains constant when the former is displaced.
The fact that no driven parts are to be moved results in a considerably simplified structural design of the longitudinal folding device. If there are several folding hoppers arranged next to one another, a single continuous hopper inlet roller is sufficient.

In Fig.1 ist mit 1 eine Trichtereinlaufwalze und mit 2 ein gegenüber dieser in Richtung seines Neigungswinkels verschiebbarer Falztrichter bezeichnet. Die Fig.1 macht deutlich, daß eine derartige Verschiebung des Falztrichters den Winkel β, mit dem die Materialbahn 1 die Trichtereinlaufwalze umschlingt, nicht verändert. Fig.1 verdeutlicht außerdem den Zusammenhang zwischen dem horizontalen Versatz x der Trichternase und dem Verschiebeweg s des Falztrichters in Richtung der Trichterneigung in Abhängigkeit vom Neigungswinkel ∝ gemäß der Beziehung x = s · cos∝ . Die Bauhöhe des gesamten Falzapparates steigt um den Wert h = x · tan∝ , was bei einer Größenordnung für h von etwa 0,15 m in den meisten Fällen ohne Belang ist.In FIG. 1, 1 denotes a former feed roller and 2 denotes a folding former that is displaceable relative to the former in the direction of its inclination angle. 1 makes it clear that such a displacement of the former is the angle β, with which the material web 1 wraps around the hopper inlet roller, not changed. Fig. 1 also illustrates the relationship between the horizontal offset x of the former and the displacement path s of the former in the direction of the former inclination depending on the angle of inclination ∝ according to the relationship x = s · cos∝. The overall height of the entire folder increases by the value h = x · tan∝, which is of no importance in most cases with a size of h of approximately 0.15 m.

Die Längsfalzvorrichtung nach Fig.2 und 3 umfaßt einen Falztrichter 2, der einer ortsfest in Gestellseitenwänden (12,13) gelagerten Trichtereinlaufwalze 1 in Bewegungsrichtung der Materialbahn nachgeordnet ist. Dieser Falztrichter ist in einem aus Seitenwänden 3 und Traversen 4 gebildeten Rahmen 5 angeordnet. Der Falztrichter 2 wird an seiner Unterseite unweit der Trichternase 2a mittels einer bekannten und daher nicht im Detail beschriebenen Vorrichtung 6 zur Feineinstellung der Trichterneigung gehalten, die in mit dem Rahmen 5 verbundenen Lagerböcken 7 axial justierbar angeordnet ist. In seinem oberen Teil ist der Falztrichter 2 an seiner Rückseite über ein Gestänge 8 und ein daran befestigtes Rohr 9 auf einer im Rahmen 5 quer eingebauten Achse 10 drehbar gelagert. Die des weiteren am Längsfalzvorgang beteiligten Aggregate, wie Trichterauslaufwalzen 11 und eventuell vorhandene, in der Zeichnung nicht dargestellte Perforiereinrichtungen, sind ebenfalls im Rahmen 5 angeordnet.The longitudinal folding device according to FIGS. 2 and 3 comprises a folding former 2, which is arranged downstream of a funnel inlet roller 1 which is fixedly mounted in frame side walls (12, 13) in the direction of movement of the material web. This former is arranged in a frame 5 formed from side walls 3 and cross members 4. The folding former 2 is held on its underside not far from the former nose 2a by means of a known and therefore not described in detail device 6 for fine adjustment of the former inclination, which is arranged axially adjustable in bearing blocks 7 connected to the frame 5. In its upper part, the former 2 is rotatably supported on its rear side via a linkage 8 and a tube 9 attached to it on an axis 10 installed transversely in the frame 5. The units also involved in the longitudinal folding process, such as funnel outlet rollers 11 and possibly existing perforating devices, not shown in the drawing, are also arranged in frame 5.

Der Rahmen 5 ist seinerseits in Gestellseitenwänden 12,13 des Falzapparates so gelagert, daß er gegenüber diesen in Richtung der Trichterneigung verschiebbar ist. Hierzu sind in den unteren Teil der Seitenwände 3 des Rahmens 5 langlochartige Führungen 14 eingearbeitet, in die an den Gestellseitenwänden 12,13 befestigte Paßbolzen 15 eingreifen. Die Längsachse der Führungen 14 liegt parallel zur Trichterneigung.The frame 5 is in turn mounted in the frame side walls 12, 13 of the folder in such a way that it can be displaced relative to the latter in the direction of the former inclination. For this purpose, slot-like guides 14 are incorporated into the lower part of the side walls 3 of the frame 5, into which fitting bolts 15 which are fastened to the frame side walls 12, 13 engage. The longitudinal axis of the guides 14 is parallel to the inclination of the funnel.

Die Verschiebebewegung geht von einer längs zu einer Gestellseitenwand 12 angeordneten und mittels Lagerböcken 17 an dieser angeflanschten Stellspindel 18 aus, an deren einem Ende zur Krafteinleitung ein Handrad 19 und an deren anderem Ende zur Kraftableitung eine Schnecke 20 angeordnet ist. Ein mit dieser Schnecke 20 kämmendes Schneckenrad 21 ist am einen Ende einer in den Gestellseitenwänden 12,13 gelagerten Synchronwelle 22 befestigt. Mit ebenfalls auf der Synchronwelle 22 angeordneten Ritzeln 23,24 stehen die Zahnkränze 25 zweier Zahnräder 26 im Eingriff, die in den Gestellseitenwänden 12,13 mit ihrem abgesetzten Bund 27 drehbar gelagert sind und auf ihrer Innenseite je ein exzentrisch angeordnetes Auge 28 aufweisen. An diesen Augen 28 ist der Rahmen 5 mit in seinen Seitenwänden 3 vorgesehenen Bohrungen 29 drehbar aufgehängt.The displacement movement starts from a longitudinally arranged to a frame side wall 12 and by means of bearing blocks 17 of this flanged adjusting spindle 18, at one end of which a handwheel 19 is arranged for the introduction of force and at the other end of which a worm 20 is arranged to derive the force. A worm wheel 21 meshing with this worm 20 is attached to one end of a synchronizer shaft 22 mounted in the frame side walls 12, 13. The sprockets 25 of two gearwheels 26, which are rotatably mounted in the frame side walls 12, 13 with their offset collar 27 and each have an eccentrically arranged eye 28 on the inside, engage with pinions 23, 24 also arranged on the synchronizer shaft 22. On these eyes 28, the frame 5 is rotatably suspended with holes 29 provided in its side walls 3.

Durch eine Drehung der Zahnräder 26 um 180° führt der Rahmen 5 eine Schwenkbewegung aus, die in Richtung der Trichterneigung eine Verschiebung s ergibt, die der zweifachen Exzentrizität e des am Zahnrad 26 befindlichen Auges 28 gegenüber dessen Mitte entspricht. Der sich bei dieser Verschiebung ergebende horizontale Verschiebeweg x errechnet sich aus x = s · cos∝, wobei mit ∝ der Winkel der Trichterneigung gegenüber der Horizontalen bezeichnet ist.By rotating the gearwheels 26 by 180 °, the frame 5 executes a pivoting movement which results in a displacement s in the direction of the funnel inclination, which corresponds to twice the eccentricity e of the eye 28 located on the gearwheel 26 relative to its center. The horizontal displacement path x resulting from this displacement is calculated from x = s · cos∝, with ∝ denoting the angle of the funnel inclination with respect to the horizontal.

In beiden Endlagen ist eine Fixierung des Rahmens gegenüber den Gestellseitenwänden 12,13 mittels in die Augen 28 der Zahnräder 26 und in die Paßbolzen 15 eingeschraubter Klemmvorrichtungen 30 möglich. In den Seitenwänden 3 des Rahmens 5 sind Aussparungen 31 vorgesehen, die eine Schwenkung des Rahmens 5 um die Synchronwelle 22 ermöglichen. Eine Kante 32 der Aussparungen 31, mit der der Rahmen 5 vor und nach einer Trichterverschiebung an der Synchronwelle 22 anliegt, ist bearbeitet und bildet eine genaue Begrenzung des Schwenkweges.In both end positions, the frame can be fixed relative to the frame side walls 12, 13 by means of clamping devices 30 screwed into the eyes 28 of the gear wheels 26 and into the fitting bolts 15. Recesses 31 are provided in the side walls 3 of the frame 5, which allow the frame 5 to be pivoted about the synchronous shaft 22. An edge 32 of the recesses 31, with which the frame 5 bears against the synchronous shaft 22 before and after a funnel displacement, is machined and forms a precise limitation of the pivoting path.

Das vorstehend beschriebene Beispiel geht von dem Anforderungsprofil aus, bei dem zwei Endstellungen des Falztrichters zur Verstellung ausreichend sind. Dies ist bei mehreren nebeneinander angeordneten Falztrichtern beispielsweise dann der Fall, wenn einer der Falztrichter unabhängig von den anderen verfahren werden soll, um dadurch die beim ersten Längsfalzvorgang parallel entstehenden Produkte geringfügig versetzt gemeinsam einem sich anschließenden Querfalzvorgang zuzuführen. Der seitliche Versatz bietet dabei für ein anschließendes Trennen der Falzerzeugnisse, beispielsweise mit Greifern, die erforderliche Angriffsmöglichkeit.The example described above is based on the requirement profile in which two end positions of the former are sufficient for adjustment. This is the case, for example, with a plurality of folding formers arranged next to one another then the case when one of the former is to be moved independently of the others in order to feed the products that arise in parallel during the first longitudinal folding process to a subsequent transverse folding process with a slight offset. The lateral offset offers the necessary possibility of attack for a subsequent separation of the folded products, for example with grippers.

Andere Produktionsarten, wie beispielsweise das Einbringen eines dritten Falzes (zweiter Längsfalz) durch einen zweiten, ortsfest quer zum ersten angeordneten Falztrichter an einer in stehendem Format bedruckten Bahn bei variierender Bahnbreite können auch eine stufenlose Verstellung des ersten Falztrichters erforderlich machen. In diesem Falle ist die Erfindung auch auf eine Längsfalzvorrichtung mit einem einzigen ersten Falztrichter anwendbar.Other types of production, such as the introduction of a third fold (second longitudinal fold) through a second, fixedly arranged transversely to the first former on a web printed in vertical format with varying web width, may also require a continuous adjustment of the first former. In this case, the invention is also applicable to a longitudinal folding device with a single first former.

Hierfür kann unter Beibehaltung des Kerngedankens der Erfindung - der Verschiebung in Richtung der Trichterneigung - folgende zweite Lösung Verwendung finden, die in den Figuren 4 und 5 dargestellt ist.
In einer Längsfalzeinrichtung ist einer Trichtereinlaufwalze 41 ein Falztrichter 42 nachgeordnet. Dieser ist in einem aus Seitenwänden 43 und Traversen 44 gebildeten Rahmen 45 angebracht. An der Unterseite des Falztrichters 42 ist unweit der Trichternase 42 a eine Vorrichtung 46 angelenkt, die zur Feineinstellung der Trichterneigung dient. Diese Vorrichtung 46 ist in mit dem Rahmen 45 verbundenen Lagerböcken 47 axial justierbar gelagert und wurde, da sie dem Fachmann bekannt ist, nicht im Detail beschrieben.The following second solution, which is illustrated in FIGS. 4 and 5, can be used for this while maintaining the core concept of the invention - the displacement in the direction of the funnel inclination.
In a longitudinal folding device, a former 42 is arranged downstream of a former entry roller 41. This is mounted in a frame 45 formed from side walls 43 and cross members 44. On the underside of the former 42, a device 46 is articulated not far from the former 42a, which is used for fine adjustment of the former inclination. This device 46 is mounted in axially adjustable manner in bearing blocks 47 connected to the frame 45 and, since it is known to the person skilled in the art, has not been described in detail.

In seinem oberen Teil ist der Falztrichter 42 über ein an seiner Rückseite angebrachtes Gestänge 48 und ein daran befestigtes Rohr 49 auf einer im Rahmen 45 quer eingebauten Achse 50 drehbar gelagert. Die des weiteren am Längsfalzvorgang beteiligten Aggregate, wie Trichterauslaufwalzen 51 und eventuell vorhandene, in der Zeichnung nicht dargestellte Perforiereinrichtungen sind ebenfalls im Rahmen 45 angebracht.In its upper part, the folding former 42 is rotatably mounted on an axis 50, which is installed transversely in the frame 45, via a linkage 48 attached to its rear side and a tube 49 attached to it. The units also involved in the longitudinal folding process, such as funnel outlet rollers 51 and possibly existing perforating devices, not shown in the drawing, are also mounted in frame 45.

Der Rahmen 45 ist in den Gestellseitenwänden 52,53 so gelagert, daß er gegenüber diesen in Richtung der Trichterneigung verschiebbar ist. Hierzu sind in die Seitenwände 43 des Rahmens 45 je zwei langlochartige Führungen 54 eingearbeitet, deren gemeinsame Längsachse parallel zur Trichterneigung liegt. In diese Führungen 54 greifen an den Gestellseitenwänden 52,53 befestigte Paßbolzen 55 ein, deren Durchmesser nur geringfügig kleiner ist als die Breite der Führungen 54. Die halbkreisförmigen Enden der Führungen 54 bilden im Zusammenwirken mit den Paßbolzen 55 Hubbegrenzungen für die Verschiebebewegung des Rahmens 45.The frame 45 is mounted in the frame side walls 52, 53 in such a way that it can be displaced relative to the latter in the direction of the funnel inclination. For this purpose, two slot-like guides 54 are incorporated into the side walls 43 of the frame 45, the common longitudinal axis of which lies parallel to the inclination of the funnel. Fit in these guides 54 on the frame side walls 52, 53 fasteners 55, the diameter of which is only slightly smaller than the width of the guides 54. The semicircular ends of the guides 54, in cooperation with the fit bolts 55, form stroke limits for the displacement movement of the frame 45.

Diese Verschiebebewegung geht von einer längs zu einer Gestellseitenwand 52 angeordneten und mittels Lagerböcken 57 an dieser angeflanschten Stellspindel 58 aus, an deren einem Ende sich zur Krafteinleitung ein Handrad 59 und an deren anderem Ende sich zur Kraftableitung eine Schnecke 60 befindet. Ein mit dieser Schnecke 60 kämmendes Schneckenrad 61 ist an einem Ende einer in den Gestellseitenwänden 52,53 gelagerten Synchronwelle 62 befestigt. Diese Synchronwelle 62 weist im Bereich der Seitenwände 43 des Rahmens 45 zwei Ritzel 65,66 auf, die mit Zahnstangenprofilen 67 zusammenwirken, welche in eine parallel zur Trichterneigung verlaufende Kante 68 einer in jeder Seitenwand 43 vorhandenen rechteckigen Aussparung 69 eingearbeitet sind. Das Zahnstangenprofil kann entweder unmittelbar in die Seitenwände 43 eingearbeitet sein oder durch eine auf der Kante 68 befestigte Zahnleiste gebildet werden.This displacement movement is based on an adjusting spindle 58 which is arranged longitudinally to a frame side wall 52 and is flanged to this by means of bearing blocks 57, at one end of which there is a handwheel 59 for the application of force and at the other end of which there is a worm 60 to derive the force. A worm wheel 61 meshing with this worm 60 is fastened to one end of a synchronous shaft 62 mounted in the frame side walls 52, 53. This synchronous shaft 62 has in the region of the side walls 43 of the frame 45 two pinions 65, 66 which cooperate with toothed rack profiles 67 which are incorporated in an edge 68 of a rectangular recess 69 in each side wall 43 which runs parallel to the funnel inclination. The rack profile can either be worked directly into the side walls 43 or be formed by a toothed strip fastened on the edge 68.

Die vorstehend beschriebene Anordnung ermöglicht eine stufenlose Trichterverstellung, deren Größtmaß durch die Länge der Führungen 54 bestimmt wird. Der Falztrichter 42 kann dabei in jeder Lage mittels in die Paßbolzen eingeschraubter, auf die Innenseiten der Seitenwände 43 des Rahmens 45 wirkender Klemmvorrichtungen 70 fixiert werden.The arrangement described above enables a stepless funnel adjustment, the largest dimension of which is determined by the length of the guides 54. The folding former 42 can be fixed in any position by means of clamping devices 70 screwed into the fitting bolts and acting on the inner sides of the side walls 43 of the frame 45.
