Description

Die Erfindung bezieht sich auf eine Falzwalzenlagerung, wie sie beispielsweise bei Rotationsdruckmaschinen nachgeordneten Falzapparaten eingesetzt werden kann.The invention relates to a folding roller bearing, as used for example in rotary printing machines downstream folders can be used.

Aus dem Stand der Technik der DE 28 46 191 C3 ist beispielsweise ein Falzapparat für Rollenrotationen bekannt geworden, bei dem ein kontinuierlicher Strom anfallender Bogenpakete durch rotierende Falzmesser in unterhalb des Falztisches angeordnete Falzwalzenpaare eingestoßen wird. Der kontinuierliche Strom anfallender Bogenpakete wurde zuvor in zwei Teilströme aufgeteilt. Zu diesem Zweck sind dem Punkturenzylinder zwei Übernahmezylinder zugeordnet. Einzelheiten der Lagerung der Falzwalzenpaare unterhalb der Falztische lassen sich der DE-PS 28 46 191 C3 nicht entnehmen.A folder for, for example, is known from the prior art of DE 28 46 191 C3 Roll rotations have become known, in which a continuous stream of resulting sheet packets by rotating folding knives in pairs of folding rollers arranged below the folding table is kicked in. The continuous flow of arches was previously divided into two sub-streams. For this purpose, the puncture cylinder is two Assigned transfer cylinder. Details of the storage of the folding roller pairs below the folding tables can not be found in DE-PS 28 46 191 C3.

DE 34 22 755 C2 bezieht sich auf einen Falzapparat für Buchfalzungen an einer Rollenrotationsdruckmaschine. Bei dem in dieser Patentschrift dargestellten Falzapparat wird der anfallende Falzproduktstrom über zwei Bandsysteme einer oberen und einer unteren Längsfalzeinheit zugeleitet. Jede der Längsfalzeinheiten umfaßt ein Falzmesser, mit welchem die Falzprodukte in Falzwalzenpaare unterhalb des Falztisches eingestoßen werden. Der Patentschrift DE 34 22 755 C2 ist entnehmbar, daß um die Falzwalzen keine Transportbänder umlaufen. Gleiches gilt für den Falzapparat mit einer zweiten Längsfalzeinrichtung, der aus DE 36 14 263 C2 bekannt ist. DE 34 22 755 C2 relates to a folder for book folds on a web-fed rotary printing press. In the folder shown in this patent, the The resulting product of the folded product over two belt systems, an upper and a lower one Longitudinal folding unit fed. Each of the longitudinal folding units comprises a folding knife with which the folding products are pushed into pairs of folding rollers below the folding table. The patent DE 34 22 755 C2 can be seen that no conveyor belts around the folding rollers circulate. The same applies to the folder with a second longitudinal folder, which is known from DE 36 14 263 C2.

DE 196 00 379 A1 bezieht sich auf eine Vorrichtung zum Transport von Exemplaren innerhalb eines Falzapparates mit einem Schneidzylinderpaar, welches einzelne Exemplare von einer Materialbahn abtrennt und die Exemplare vom Schneidzylinderpaar zu einem exemplarführenden Zylinder befördert werden, wobei dem Schneidzylinderpaar oder dem exemplarführenden Zylinder Bänderzüge zum Transport von Exemplaren zugeordnet sind. Die Umlenkorgane für die jeweiligen Transportbänderzüge und exemplarführenden Komponenten sind an einem Ende durch Stellorgane freilegbar.
Es hat sich herausgestellt, daß sich beispielsweise das Auswechseln einzelner Transportbänder in Transportbänderzügen, die unterhalb eines Falztisches oder ähnlich schwer zugänglich angeordnet sind, sehr langwierig und zeitraubend gestaltet. Das jeweils auszuwechselnde Transportband kann an Ort und Stelle beispielsweise um die Falzwalze geführt und dann vor Ort wieder zusammengefügt werden. Andererseits muß bei den bisherigen Falzwalzenkonstruktionen bei Aufziehen eines endlosen, fertigen Transportbandes, was keine zusammenfügbaren Enden mehr aufweist, entweder die gesamte Falzwalze oder eine Lagerungsstelle derselben komplett ausgebaut werden, da sich das endlose Band nur so axial auf die Falzwalze aufziehen läßt. Die beiden skizzierten Auswechselvorgänge sind äußerst zeitraubend, schwierig auszuführen und schränken die Verfügbarkeit eines Falzapparates für die Exemplarproduktion nicht unerheblich ein.
DE 196 00 379 A1 relates to a device for transporting specimens within a folder with a pair of cutting cylinders, which separates individual specimens from a material web and the specimens are conveyed from the pair of cutting cylinders to a specimen-guiding cylinder, with the cutting cylinder pair or the specimen-guiding cylinder belt pulls for transport of copies are assigned. The deflecting elements for the respective conveyor belts and components carrying the specimen can be exposed at one end by adjusting elements.
It has been found that, for example, the replacement of individual conveyor belts in conveyor belt trains which are arranged below a folding table or similarly difficult to access is very lengthy and time-consuming. The conveyor belt to be replaced in each case can, for example, be guided around the folding roller on site and then reassembled on site. On the other hand, with the previous folding roller constructions, when pulling on an endless, finished conveyor belt, which no longer has any ends that can be joined, either the entire folding roller or a storage location thereof must be completely removed, since the endless belt can only be pulled onto the folding roller axially. The two exchange processes outlined are extremely time-consuming, difficult to carry out and considerably reduce the availability of a folder for the production of copies.

Angesichts des aufgezeigten Standes der Technik und dem aufgezeigten technischen Problem, liegt der Erfindung die Aufgabe zugrunde, das Auswechseln von Transportbändern an schwierig zugänglichen Rotationskörpern zu erleichtern.In view of the state of the art and the technical problem shown, the invention has for its object the replacement of conveyor belts on rotating bodies that are difficult to access.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Patentanspruches 1 gelöst.According to the invention, this object is achieved by the features of patent claim 1.

Die erfindungsgemäße Lösung geht mit zahlreichen Vorteilen einher. Die leichte, ferngesteuerte bewirkbare Freigabe eines Endes der Falzwalzen ermöglicht auf einfache Weise einen Austausch schadhafter oder verbrauchter Transportbänder. Durch das anstellbare, antriebsseitig vorgesehene Gegenlager ist die an einem Ende freigelegte Falzwalze stabil in einer der Seitenwände arretiert. Das die Falzwalze nunmehr einseitig in der Seitenwand abstützende Kugellager wird möglichst geschont, da ein Verkippen in der Seitenwand verhindert wird. Nach erfolgter Auswechslung der Transportbänder und dem Wiederaufziehen derselben auf ihre zugehörigen Laufflächen auf den Falzwalzenmänteln kann eine Wiederaufnahme der Produktion rasch erfolgen. Produktionszeitverlust aufgrund schadhafter Transportbänder können nunmehr auf ein Minimum begrenzt werden. In weiterer Ausgestaltung des der Erfindung zugrundeliegenden Gedankens sind die Falzwalzen an einer ihrer Stirnseiten mit einer Ausnehmung versehen, in die der axial verfahrbare Lagerungszapfen einfahren und aus welcher dieser auch wieder ausfahren kann. In dieser Ausnehmung kann eines der seitlichen Kugellager der Falzwalzen eingelassen sein, dessen Lagerinnenfläche dann als die Kontaktzone mit dem eingefahrenen Lagerungszapfen fungiert. Der Antrieb, mit welchem der Lagerungszapfen in axialer Richtung verfahrbar ist, kann ein pneumatischer, hydraulischer oder auch ein elektrischer Antrieb sein. Auch eine manuelle Bedienbarkeit des Lagerungszapfens in axialer Richtung wäre denkbar. Die auf den Walzenmänteln der Falzwalzen verlaufenden Transportbänder können in sich ringförmig auf den Walzenmänteln der Falzwalzen erstreckenden Ausnehmungen geführt sein.The solution according to the invention has numerous advantages. The light, remote controlled effective release of one end of the folding rollers enables in a simple manner an exchange of damaged or used conveyor belts. The adjustable, counter-bearing provided on the drive side, the folding roller exposed at one end is stable in one of the side walls locked. The folding roller is now one-sided in the side wall Supporting ball bearings are protected as much as possible, since tilting in the side wall prevents them becomes. After replacement of the conveyor belts and re-opening the same on their associated treads on the folding roller jackets can be resumed of production take place quickly. Loss of production time due to defective Conveyor belts can now be kept to a minimum. In a further embodiment of the idea on which the invention is based are the folding rollers on one their end faces with a recess into which the axially movable bearing pin drive in and out of which it can also exit again. In this recess one of the side ball bearings of the folding rollers can be embedded, the inner surface of the bearing then acts as the contact zone with the retracted journal. The drive with which the bearing pin can be moved in the axial direction can be a be pneumatic, hydraulic or also an electric drive. Also a manual one Operability of the bearing pin in the axial direction would be conceivable. The one on the roller coats of the folding rollers running conveyor belts can be in a ring the roller shells of the folding rollers extending recesses.

Solange der axial verfahrbare Lagerungszapfen in die stirnseitig vorgesehene Ausnehmung der Falzwalze eingefahren bleibt, verbleibt das antriebsseitig vorgesehene Gegenlager zur Abstützung der an einem Ende freigelegten Falzwalze in aktiver Position und berührt die Oberfläche des antriebsseitigen Wellenzapfens der Falzwalze nicht. Sobald hingegen der verfahrbare Lagerungszapfen aus der Ausnehmung der Falzwalze ausfährt, setzt das Gegenlager auf das gegenüberliegende antriebsseitige Ende des Wellenzapfens der Falzwalze auf und hält diese in ihrer freigelegten Position, sodaß ein rasches Auswechseln einzelner oder aller Transportbänder erfolgen kann.As long as the axially movable bearing pin in the recess provided on the face If the folding roller remains retracted, the counter bearing provided on the drive side remains Support of the folding roller exposed at one end in the active position and touches the Surface of the drive side shaft journal of the folding roller is not. However, as soon as the Moves the bearing pin out of the recess of the folding roller, sets the counter bearing on the opposite drive-side end of the shaft journal of the folding roller on and holds them in their exposed position, so that a quick replacement of individual or all conveyor belts.

Anhand einer Zeichnung sei die Erfindung nachstehend en detail erläutert.The invention is explained in detail below with reference to a drawing.

Fig. 1 zeigt ein Ausführungsbeispiel einer konventionellen Falzwalzenkonstruktion.Fig. 1 shows an embodiment of a conventional folding roller construction.

Die Falzwalze 1 ist an beiden Enden mittels konventioneller Lager 4, 5 in den Seitenwänden 6, 7 beispielsweise einer zweiten Längsfalzeinrichtung unterhalb eines Falztisches aufgenommen. Die Falzwalze 1 umfaßt einen Falzwalzenmantel 2, auf dessen Oberfläche senkrecht zu einer Rotationsachse 11 der Falzwalzen 1 ringförmig verlaufende Ausnehmungen 13 vorgesehen sind, in denen die Transportbänder 3 geführt sind. Aus Fig. 1 ist zudem ersichtlich, daß ein sich antriebsseitig erstreckender Wellenzapfen 10 mittels des Lagers 4 in der antriebsseitigen Seitenwand 6 aufgenommen ist; ferner ist auf dem Wellenzapfen 10 ein Antriebszahnrad 8 gelagert; anstelle dessen könnte ebensogut eine Riemenscheibe oder ein direkter elektrischer Antrieb den Falzwalzen 1 zugeordnet sein.The folding roller 1 is at both ends by means of conventional bearings 4, 5 in the side walls 6, 7, for example, a second longitudinal folding device below a folding table added. The folding roller 1 comprises a folding roller jacket 2 on its surface Recesses running perpendicular to a rotation axis 11 of the folding rollers 1 13 are provided, in which the conveyor belts 3 are guided. From Fig. 1 can also be seen that a drive shaft extending on the drive side 10 by means of Bearing 4 is received in the drive side wall 6; is also on the shaft journal 10 a drive gear 8 is mounted; instead, a pulley might as well or a direct electric drive can be assigned to the folding rollers 1.

Das gegenüberliegende Ende der Falzwalze 1 umfaßt einen im Vergleich zum Wellenzapfen 10 stark verkürzten Wellenstummel, der mittels eines Lagers 5 in der Seitenwand 7 aufgenommen ist. Die der Stirnseite 12 zugeordnete Lagerungsstelle ist somit gehäusefest ausgeführt, die darin gelagerte Falzwalze 1 kann nicht ohne weiteres an einem ihrer Enden freigelegt werden.The opposite end of the folding roller 1 comprises one compared to the shaft journal 10 greatly shortened stub shaft, which by means of a bearing 5 in the side wall 7 is recorded. The bearing point assigned to the end face 12 is thus fixed to the housing executed, the folding roller 1 stored therein can not easily at one of its ends be exposed.

Fig. 2 zeigt eine erfindungsgemäße Falzwalzenkonfiguration mit in eine stirnseitige Ausnehmung eingefahrenem Lagerungszapfen und gerade noch nicht angestelltem Gegenlager.Fig. 2 shows a folding roller configuration according to the invention with in an end recess retracted bearing journal and counter bearing not just started.

Der in Fig. 2 dargestellten Falzwalze ist ein Gegenlager 14 auf der Antriebsseite zugeordnet. Dieses Gegenlager 14 kann im einfachsten Fall als ein sich von oben auf den Wellenzapfen 10 aufsetzendes Element ausgebildet sein. Im in Fig. 2 dargestellten Zustand ist das Gegenlager 14 um den Abstand von etwa 0,2 mm von der Oberfläche des Wellenzapfens 10 abgestellt und berührt diesen gerade nicht. Das Gegenlager 14 könnte auch als ein das Ende des Wellenzapfens 10 ringförmig umschließendes Element ausgeführt sein, oder auch unterhalb des Wellenzapfens 10 an der Antriebsseitenwand 6 gelagert sein. Das Gegenlager 14 kann pneumatisch oder hydraulisch betätigbar sein oder durch einen eigens zugeordneten elektromotorischen Antrieb betätigt werden.A counter bearing 14 on the drive side is assigned to the folding roller shown in FIG. 2. In the simplest case, this counter bearing 14 can be seen from above on the shaft journal 10 touchdown element be formed. In the state shown in Fig. 2 the counter bearing 14 by the distance of about 0.2 mm from the surface of the shaft journal 10 turned off and does not touch it. The counter bearing 14 could also be a the end of the shaft journal 10 may be designed in a ring-enclosing element, or also be mounted on the drive side wall 6 below the shaft journal 10. The counter bearing 14 can be operated pneumatically or hydraulically or by one assigned electric motor drive can be operated.

An der Stirnseite 12 der Falzwalze 1 ist eine Ausnehmung 22 vorgesehen, in welcher der Lagerungszapfen 17 in hier gezeigten Zustand eingefahren ist. Der verschiebbare Lagerungszapfen 17 stützt das Lager 16 der Falzwalze 1 ab und ist seinerseits über eine Kolbenstange oder ein gleichartiges Bauelement 19 mit einem Stellantrieb 18 verbunden. Mittels des Stellantriebes 18 wird dem verfahrbaren Lagerungszapfen 17 seine Axialbewegung aufgeprägt, welche zur Freigabe der Stirnseite 12 der Falzwalze 1 führt. Analog zum Antrieb für das Gegenlager 14 kann der Stellantrieb 18 aus einem pneumatischen, hydraulischen oder elektromotorischen Antrieb bestehen. Ein kulissenartiger Antrieb ist ebenso denkbar wie ein Zahnstangenantrieb oder ein elektromagnetischer Antrieb, der zwischen zwei Stellspositionen hin- und herschaltbar ist. Auf der in Fig. 2 dargestellten erfindungsgemäßen Falzwalze 1 befinden sich mehrere ringförmig um die Rotationsachse 11 erstrekkende Ausnehmungen 13, in denen jeweils eines der Transportbänder 3 der Transportbänderzüge aufgenommen ist, die um die Falzwalze 1 umlaufen. Die Transportbänder 3 dienen zur Führung der Falzprodukte, nachdem der Falzrücken eines Falzproduktes durch ein hier nicht dargestelltes Falzmesser in den Spalt zwischen den beiden Falzwalzen eingestoßen wurde. Durch die beiden miteinander zusammenarbeitenden Falzwalzen 1, wird der zweite Längsfalz, erzeugt durch die Eintauchbewegung des Falzmessers zwischen die beiden Falzwalzen 1 weiter ausgebildet. Von den beiden miteinander den zweiten Längsfalz weiter ausbildenden Falzwalzen 1 sind in den Seitenansichten nur jeweils eine Falzwalze 1 wiedergegeben, wie auch der dazugehörige Falztisch oberhalb der Falzwalzen 1, sowie das sich auf- und abbewegende Falzmesser der zweiten Längsfalzeinrichtung nicht dargestellt wurden.On the end face 12 of the folding roller 1, a recess 22 is provided, in which the Bearing pin 17 is retracted in the state shown here. The sliding bearing pin 17 supports the bearing 16 of the folding roller 1 and is in turn via a piston rod or a similar component 19 connected to an actuator 18. By means of the actuator 18, the movable bearing journal 17 becomes its axial movement impressed, which leads to the release of the end face 12 of the folding roller 1. Analogous to The actuator for the counter bearing 14 can be the actuator 18 from a pneumatic, hydraulic or electric motor drive exist. A backdrop-like drive is also conceivable like a rack and pinion drive or an electromagnetic drive that is between two positions can be switched back and forth. On the invention shown in Fig. 2 Folding roller 1 is a plurality of rings extending around the axis of rotation 11 Recesses 13, in each of which one of the conveyor belts 3 of the conveyor belt trains is recorded, which revolve around the folding roller 1. The conveyor belts 3 serve to guide the folded products after the folded back of a folded product by a here Push not shown folding knife into the gap between the two folding rollers has been. Due to the two folding rollers 1 working together, the second one Longitudinal fold, created by the plunge movement of the folding knife between the two Folding rollers 1 further developed. From the two together the second longitudinal fold forming folding rollers 1 are only one folding roller 1 in each of the side views reproduced, as well as the associated folding table above the folding rollers 1, and the folding knife moving up and down of the second longitudinal folding device is not shown were.

Die Falzwalzen 1 werden antriebsseitig beispielsweise mittels eines Zahnrades 8 angetrieben; auch der Einsatz von Riemenscheiben ist möglich. Den Falzwalzen 1 könnte darüber hinaus alternativ ein Direktantrieb zugeordnet sein, der die Falzwalzen 1 mit einer vorherbestimmbaren Umfangsgeschwindigkeit antreibt.The folding rollers 1 are driven on the drive side, for example by means of a toothed wheel 8; the use of pulleys is also possible. The folding roller 1 could over it In addition, a direct drive can alternatively be assigned to the folding rollers 1 with a predeterminable one Peripheral speed drives.

Fig. 3 zeigt die erfindungsgemäße Falzwalze mit antriebsseitig aktiviertem Gegenlager und aus der Ausnehmung der Falzwalze ausgefahrenem Lagerungszapfen.3 shows the folding roller according to the invention with the counter bearing and activated on the drive side bearing journal extended from the recess of the folding roller.

In der Fig. 3 ist mit Bezugszeichen 21 die Freigabeposition der Stirnseite 12 der Falzwalze 1 bezeichnet; unmittelbar nachdem über dem Stellantrieb 18 die axiale Ausfahrbewegung des Lagerungszapfens 17 aus der Ausnehmung gebildet durch die Lagerinnenfläche 23 begonnen hat, setzt sich das Gegenlager 14 auf den Wellenzapfen 10 auf und hält somit die Falzwalze 1 in horizontaler Lage. Bezugszeichen 24 bezeichnet die Abstützposition der Falzwalze 1 durch das Gegenlager 14. Dieses setzt auf den Wellenzapfen 10 im Kontaktbereich 15 auf, oder umschließt diesen dort, je nach Ausführungsform und Position des Gegenlagers 14. Der verfahrbare Lagerungszapfen 17 ist durch den Stellantrieb 18 in seine Bohrung in die Seitenwand 7 zurückgefahren, wodurch sich zwischen der Stirnseite 12 und der Seitenwand 7 ein Freiraum ergibt. Durch diesen Freiraum können dann verschlissene und erneuerungsbedürftige Transportbänder 3 von den Falzwalzenmänteln 2 entfernt werden und neue wieder auf diesen montiert werden. Dann fährt der verfahrbare Lagerungszapfen 17 wieder in die Ausnehmung 22 ein. So dann ist die Falzwalze beidseitig gelagert, das Gegenlager 14 gibt den Wellenzapfen 10 wieder frei, so daß die Falzwalze 1 über beispielsweise das Zahnrad 8 wieder frei angetrieben werden kann. In Fig. 3, reference numeral 21 is the release position of the end face 12 of the folding roller Denotes 1; immediately after the actuator 18 the axial extension movement of the bearing pin 17 formed from the recess by the inner surface of the bearing 23 has begun, the counter bearing 14 sits on the shaft journal 10 and stops thus the folding roller 1 in a horizontal position. Numeral 24 denotes the support position the folding roller 1 through the counter bearing 14. This is based on the shaft journal 10 in Contact area 15, or encloses it there, depending on the embodiment and position of the counter bearing 14. The movable bearing pin 17 is by the actuator 18 in retracted its hole in the side wall 7, causing itself between the end face 12 and the side wall 7 gives a free space. This space can then be worn out and conveyor belts 3 in need of renovation from the folding roller jackets 2 are removed and new ones are mounted on them. Then the movable one drives Bearing pin 17 in the recess 22 again. Then the folding roller is on both sides stored, the counter bearing 14 releases the shaft journal 10 again, so that the folding roller 1 can be driven freely again, for example via the gear 8.
