Abstract

The rotatably mounted supporting arrangement (12) comprises two receiving claws (30) having V-shaped grooves (34). Lying diametrically opposite these receiving claws (30) are two clamping claws (32) which likewise have V-shaped grooves (34). The web-roll core (10) has on its inner side a circumferential flange (24) which is of V-shaped design. The flange (24) is supported in the grooves (34) of the receiving claws (30) and is pressed against the latter by means of the clamping claws (32). For the releasable clamping of the web-roll core (10), the clamping claws (32) can be moved from a rest position in which they do not lie against the core (10), into a working position in which, together with the receiving claws (30), they clamp the core (10). The core (10) with its roll (18) is clamped against the supporting arrangement (12) and mounted rotatably together with this. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum drehbaren Lagern eines hohlzylindrischen Wickelkerns gemäss dem Oberbegriff des Anspruchs 1 und einen hohlzylindrischen Wickelkern mit einer auf seiner aussenliegenden Seite angeordneten Tragfläche zum Tragen eines Wickels aus biegsamen, flächigen Erzeugnissen, insbesondere Druckereiprodukten.The present invention relates to a device for the rotatable mounting of a hollow cylindrical winding core according to the preamble of claim 1 and a hollow cylindrical winding core with a support surface arranged on its outer side for carrying a roll of flexible, flat products, in particular printed products.

Eine Vorrichtung, die die Merkmale des Oberbegriffs des Anspruchs 1 aufweist, ist aus der EP-A-0 243 837 bzw. der entsprechenden US-A-4,768,768 bekannt. An einer von einem transportierbaren Gestell in horizontaler Richtung abstehenden Welle ist eine Hülse einer Stützanordnung drehbar gelagert. An dieser Hülse sind drei radial abstehende Stützarme befestigt. Einer dieser Stützarme ist mit einer ein- und ausfahrbaren Stütze versehen. Ein hohlzylinderförmiger Wickelkern, dessen aussenliegende Seite zum Tragen eines Wickels aus Druckereiprodukten bestimmt ist, wird bei eingefahrener Stütze mit seiner innenliegenden, zylindrischen Seite auf die beiden anderen Stützarme abgesetzt. Durch Ausfahren der Stütze wird der Wickelkern an der Stützanordnung lösbar festgeklemmt.A device having the features of the preamble of claim 1 is known from EP-A-0 243 837 or the corresponding US-A-4,768,768. A sleeve of a support arrangement is rotatably mounted on a shaft projecting from a transportable frame in the horizontal direction. Three radially protruding support arms are attached to this sleeve. One of these support arms is provided with a retractable and extendable support. A hollow cylindrical winding core, the outer side of which is intended to carry a winding of printed products, is placed with the inner, cylindrical side onto the other two support arms when the support is retracted. By extending the support, the winding core is releasably clamped to the support arrangement.

Eine weitere Vorrichtung zum Lagern eines hohlzylindrischen Wickelkerns ist beispielsweise aus der EP-OS 0 161 569 bzw. der entsprechenden US-A-4,601,436 bekannt. Die Stützanordnung dieser Vorrichtung weist zwei parallelachsige Stützräder auf, die an einem Gestell drehbar und antreibbar gelagert sind. Die beiden Stützräder sind Teile eines Reibradgetriebes, zu welchem ein weiteres ringförmiges Reibrad gehört, welches zugleich Wickelkern ist, auf dem Druckereiprodukte zusammen mit einem Wickelband aufgewickelt sind. Die innenliegende Mantelfläche des Wickelkerns kommt auf die beiden Stützräder zur Auflage und dient als Lauffläche, welche seitlich durch nach innen vorstehende Seitenflansche begrenzt ist. Bei auf die Stützräder aufgelegtem Wickelkern verläuft dessen Längsachse folglich parallel zu den Drehachsen der Stützräder. Unterhalb und in der Mitte zwischen den Stützrädern ist ein Führungsrad angeordnet, das von einer Ruhestellung in eine Arbeitsstellung bringbar ist, in welcher es ebenfalls an der innenliegenden Mantelfläche anliegt, um den Wickelkern an die beiden Stützräder zu drücken. Diese bekannte Vorrichtung ist aufwendig im Aufbau, müssen doch die beiden Stützräder angetrieben werden und weiters muss, um ein Schlüpfen des Reibradgetriebes zu verhindern, ein Führungsrad vorgesehen werden.Another device for supporting a hollow cylindrical winding core is known for example from EP-OS 0 161 569 or the corresponding US-A-4,601,436. The support arrangement of this device has two parallel-axis support wheels which are rotatably and drivably mounted on a frame. The two support wheels are parts of a friction gear, to which a further ring-shaped friction wheel belongs, which is also a winding core, on which printed products are wound together with a winding belt. The inner surface of the winding core comes to rest on the two support wheels and serves as a running surface, which is laterally delimited by inwardly projecting side flanges. When the winding core is placed on the support wheels, its longitudinal axis consequently runs parallel to the axes of rotation of the support wheels. A guide wheel is arranged below and in the middle between the support wheels, which can be brought from a rest position into a working position in which it is also on the inside The outer surface rests to press the winding core against the two support wheels. This known device is complex in construction, since the two support wheels have to be driven and, furthermore, a guide wheel must be provided in order to prevent the friction gear transmission from slipping.

Weiter ist aus der EP-OS 0 236 561 ein Wickelkern bekannt, der auf seiner Aussenseite eine Tragfläche zum Tragen eines Wickels von Druckereiprodukten aufweist. Die Druckereiprodukte sind zusammen mit einem einerends am Wickelkern befestigten Wickelband aufgewickelt. Der Wickelkern weist eine gegen die Aussenseite hin offene Nut für das Wickelband auf, und auf seiner Innenseite sind zwei umlaufende Stege angeordnet, die in rechtwinklig zur Längsachse des Wickelkerns verlaufenden Ebenen liegen, welche ausserhalb des Schwerpunktes des Wickelkerns verlaufen. Zum drehbaren Lagern dieses Wickelkerns muss er entweder auf beiden Stegen abgestützt werden oder er wird auf einem Steg abgestützt, wobei aber eine axiale Abstützung des Wickelkerns notwendig ist, um ein Abkippen zu vermeiden.Furthermore, a winding core is known from EP-OS 0 236 561, which has an outer surface on its outside for carrying a winding of printed products. The printed products are wound together with a winding tape attached to one end of the winding core. The winding core has a groove for the winding tape that is open towards the outside, and on its inside are arranged two circumferential webs that lie in planes that run at right angles to the longitudinal axis of the winding core and that extend outside the center of gravity of the winding core. For the rotatable mounting of this winding core, it must either be supported on both webs or it is supported on a web, but an axial support of the winding core is necessary to avoid tipping.

Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zum drehbaren Lagern eines hohlzylindrischen Wickelkerns, der auf seiner aussenliegenden Seite zum Tragen eines Wickels aus biegsamen, flächigen Erzeugnissen, insbesondere Druckereiprodukten, bestimmt ist, zu schaffen, die einfach im Aufbau und sicher im Betrieb ist. Weiter soll ein hohlzylindrischer Wickelkern vorgeschlagen werden, der sich für diese Vorrichtung besonders gut eignet und ebenfalls sehr einfach im Aufbau ist.The object of the present invention is to provide a device for the rotatable mounting of a hollow cylindrical winding core, which is intended on its outer side for carrying a roll of flexible, flat products, in particular printed products, which is simple in construction and reliable in operation. Furthermore, a hollow cylindrical winding core is to be proposed which is particularly well suited for this device and which is also very simple in construction.

Diese Aufgabe wird durch eine gattungsgemässe Vorrichtung die die Merkmale des kennzeichnenden Teiles des Anspruches 1 bzw. einen Wickelkern gemäss Anspruch 12 gelöst.This object is achieved by a generic device which has the features of the characterizing part of claim 1 or a winding core according to claim 12.

Das Stützelement und das Andrückelement klemmen den Wickelkern fest an die Stützanordnung, so dass der Wickelkern beim Drehen der Stützanordnung mit dieser mitdreht. Dadurch wird ein ruhiger Lauf erzielt, weil zwischen der Stützanordnung und dem Wickelkern keine Relativbewegungen entstehen können. Die Vorrichtung wird auch sehr einfach, da die ganze Stützanordnung drehbar gelagert werden kann und die Stützanordnung selber nur als Klemmanordnung für den Wickelkern auszubilden ist.The support element and the pressing element clamp the winding core firmly to the support arrangement, so that the winding core rotates with the support arrangement when it rotates. This ensures smooth running because no relative movements can occur between the support arrangement and the winding core. The device also becomes very simple since the entire support arrangement can be rotatably supported and the support arrangement itself is only to be designed as a clamping arrangement for the winding core.

Die etwa V-förmige Ausbildung des Stützelements und des Andrückelements lässt grosse Toleranzen für die gesamte Stützanordnung mit dem Stütz und Andrückelement sowie für den Wickelkern zu. Ebenfalls wird ein beispielsweise versetzt auf die Stützanordnung abgesetzter Wickelkern durch V-förmigen Nuten selbstätig zentriert und ausgerichtet, was ein einfaches Handling gewährleistet und wodurch eine gute Stabilität erreicht werden kann.The approximately V-shaped design of the support element and the pressure element allows large tolerances for the entire support arrangement with the support and pressure element and for the winding core. Likewise, a winding core, for example offset on the support arrangement, is automatically centered and aligned by means of V-shaped grooves, which ensures simple handling and as a result good stability can be achieved.

Ein hohlzylindrischer Wickelkern, der sich besonders gut zum drehbaren und abnehmbaren Lagern an einer Stützanordnung der Vorrichtung gemäss Anspruch 1 eignet, weist ein Lagerungselement mit einem im wesentlichen V-förmigen Querschnitt auf. Der Wickelkern wird mit seinem Lagerungselement auf das Stützelement abgesetzt und das Andrückelement wirkt auf das Lagerungselement derart ein, dass der Wickelkern an der Stützanordnung festgeklemmt ist. Dadurch wird eine besonders stabile, gut zentrierte und grosse Toleranzen am Wickelkern sowie an der Stützanordnung zulassende Verbindung zwischen dem Wickelkörper und der Stützanordnung erreicht.A hollow cylindrical winding core, which is particularly well suited for rotatable and removable mounting on a support arrangement of the device according to claim 1, has a bearing element with a substantially V-shaped Cross section on. The winding core is placed with its bearing element on the support element and the pressing element acts on the bearing element in such a way that the winding core is clamped on the support arrangement. As a result, a particularly stable, well-centered and large tolerances are achieved on the winding core and on the connection between the winding body and the support arrangement, which connection permits.

In einer besonders geeigneten Ausführungsform ist das Lagerungselement durch einen nach der innenliegenden Seite vorstehenden, umlaufenden Steg gebildet, der als im wesentlichen V-förmiger Keil ausgebildet ist. Ein solcher Wickelkern eignet sich insbesondere für eine Stützanordnung gemäss Anspruch 11.In a particularly suitable embodiment, the bearing element is formed by a circumferential web projecting towards the inside, which is designed as an essentially V-shaped wedge. Such a winding core is particularly suitable for a support arrangement according to claim 11.

Fig. 1 zeigt einen Wickelkern 10, welcher an einer an einem in dieser Fig. nicht sichtbaren Lagerbock drehbar gelagerten Stützanordnung 12 festgeklemmt ist. Der Lagerbock ist in bekannter, auf nicht näher gezeigte Weise an Schienen 14 höhenverstellbar gelagert.1 shows a winding core 10 which is clamped to a support arrangement 12 which is rotatably mounted on a bearing block which is not visible in this FIG. The bearing block is mounted on rails 14 in a known, height-adjustable manner in a manner not shown.

Der Wickelkern 10 ist hohlzylindrisch aufgebaut und weist auf seiner aussenliegenden Seite eine Tragfläche 16 auf, welche einen Wickel 18 aus nur andeutungsweise dargestellten Druckereiprodukten 20 trägt. Die Druckereiprodukte 20 sind in bekannter Art und Weise zusammen mit einem Wickelband 22 auf dem Wickelkern 10 aufgewickelt, wobei das Wickelband 22 einerends am Wickelkern 10 befestigt ist und andernends den Wickel 18 umgreift, um diesen zusammenzuhalten. Der Wickelkern 10 weist einen nach der innenliegenden Seite vorstehenden als Lagerungselement ausgebildeten, umlaufenden Steg 24 auf, dessen innerer Endbereich als V-förmiger Keil 26 ausgebildet ist. Vom Steg 24 stehen in Axialrichtung des Wickelkerns l0 verlaufende Versteifungskörper 28 ab, um die Tragfläche 16 zu versteifen.The winding core 10 is constructed as a hollow cylinder and has on its outer side a support surface 16 which carries a winding 18 made of printed products 20, which are only indicated in the illustration. The printed products 20 are wound in a known manner together with a winding tape 22 on the winding core 10, the winding tape 22 being fastened on one end to the winding core 10 and on the other hand engaging around the winding 18 in order to hold it together. The winding core 10 has a circumferential web 24, which protrudes on the inside as a bearing element and whose inner end region is designed as a V-shaped wedge 26. From the web 24 projecting in the axial direction of the winding core 10 stiffening body 28 to stiffen the wing 16.

An der Stützanordnung 12 sind zwei, als Stützelemente ausgebildete Aufnahmepratzen 30 und zwei, diesen diametral gegenüberliegende, als Andrückelemente ausgebildete Spannpratzen 32 vorgesehen. Die Aufnahmepratzen 30 und Spannpratzen 32 weisen V-förmige Nuten 34 auf, welche am V-förmigen Keil 26 des Wickelkerns 10 anliegen. Die Aufnahmepratzen 30 und Spannpratzen 32 bilden somit eine Klemmanordnung für den Wickelkern 10 und klemmen diesen an der Stützanordnung 12 fest. Wie dies weiter unten beschrieben ist, sind die Spannpratzen 32 schwenkbar gelagert, so dass sie ausser Eingriff mit dem V-förmigen Keil 26 gebracht werden können, und der Wickelkern 10 mit samt den darauf zu einem Wickel 18 aufgewickelten Druckereiprodukten 20 von den Aufnahmepratzen 30 abgehoben werden kann. Wie dies ebenfalls weiter unten näher beschrieben ist, ist an den Aufnahmepratzen 30 ein plattenförmiger Hebel 36 schwenkbar gelagert, welcher an seinem freien Ende drehbar gelagerte Walzen 38 aufweist. An den Spannpratzen 32 ist eine diese miteinander verbindende plattenförmige Abrollkulisse 40 befestigt, welche sich an den Walzen 38 abstützt. Am Hebel 36 sind zwei seitlich vorstehende Stifte 42 angeordnet, auf welche je eine erste und eine zweite Feder 44, 46 einwirkt, von welchen in der Fig. 1 je nur eine dargestellt ist. Die zweite Feder 46 ist einerends am einem Stift 42 und andernends an einer Spannpratze 32 befestigt. Die erste Feder 44 spannt den Hebel 36 gegen eine Ruhestellung vor, während die zweite Feder 46 die Spannpratzen 32 gegen eine Ruhestellung vorspannt. Am Hebel 36 sind Sicherheitsanschlagnocken 48 vorgesehen, deren Aufgabe weiter unten beschrieben ist. Der Vollständigkeit halber sei noch erwähnt, dass die Stützanordnung 12, und somit der an dieser festgeklemmte Wickelkern 10 mit dem Wickel 18, in Pfeilrichtung A am nicht dargestellten Lagerbock drehbar gelagert ist.Two support claws 30, designed as support elements, and two clamping claws 32, diametrically opposite these, designed as pressure elements, are provided on the support arrangement 12. The receiving claws 30 and clamping claws 32 have V-shaped grooves 34, which on V-shaped wedge 26 of the winding core 10 abut. The holding claws 30 and clamping claws 32 thus form a clamping arrangement for the winding core 10 and clamp it firmly on the support arrangement 12. As described further below, the clamping claws 32 are pivotally mounted so that they can be disengaged from the V-shaped wedge 26, and the winding core 10 together with the printed products 20 wound thereon to form a winding 18 are lifted off the mounting claws 30 can be. As is also described in more detail below, a plate-shaped lever 36 is pivotally mounted on the mounting claws 30 and has rollers 38 rotatably mounted on its free end. A plate-shaped rolling link 40, which connects them to one another and is supported on the rollers 38, is fastened to the clamping claws 32. Arranged on the lever 36 are two laterally projecting pins 42, each of which acts on a first and a second spring 44, 46, only one of which is shown in FIG. 1. The second spring 46 is attached at one end to a pin 42 and at the other end to a clamping claw 32. The first spring 44 prestresses the lever 36 against a rest position, while the second spring 46 prestresses the clamping claws 32 against a rest position. Safety stop cams 48 are provided on the lever 36, the task of which is described below. For the sake of completeness, it should also be mentioned that the support arrangement 12, and thus the winding core 10 clamped to it with the winding 18, is rotatably mounted in the direction of arrow A on the bearing block, not shown.

Fig. 2 zeigt einen Schnitt entlang der Linie II-II der Fig. 1, wobei der Wickel 18 und der Lagerbock 50 nur teilweise dargestellt sind. Wie weiter oben beschrieben, ist der Lagerbock 50 an den in der Fig. 2 nicht dargestellten Schienen 14 (siehe Fig. 1) höhenverstellbar gelagert. Am Lagerbock 50 ist eine um ihre strichpunktiert angedeutete Drehachse 52 drehbar antreibbare Hohlwelle 54 gelagert. Die Hohlwelle 54 trägt einen Flansch 56, an welchem ein plattenförmiges Halteelement 58 der Stützanordnung 12 fixiert ist. Am Halteelement 58 sind die beiden Aufnahmepratzen 30, von welchen in der Fig. 2 nur eine sichtbar ist, befestigt. Die Aufnahmepratzen 30 stehen vom Halteelement 58 in einer Richtung parallel zur Drehachse 52 ab und weisen in ihren Endbereichen, die schon weiter oben erwähnten V-förmigen, in radialer Richtung gesehen gegen aussen hin offenen Nuten 34 auf.Fig. 2 shows a section along the line II-II of Fig. 1, the winding 18 and the bracket 50 only are partially shown. As described above, the bearing block 50 is mounted on the rails 14 (see FIG. 1), which are not shown in FIG. 2, and are height-adjustable. A hollow shaft 54 which can be driven rotatably about its axis of rotation 52, indicated by dash-dotted lines, is mounted on the bearing block 50. The hollow shaft 54 carries a flange 56 on which a plate-shaped holding element 58 of the support arrangement 12 is fixed. The two holding claws 30, of which only one is visible in FIG. 2, are attached to the holding element 58. The holding claws 30 protrude from the holding element 58 in a direction parallel to the axis of rotation 52 and have, in their end regions, the V-shaped grooves 34 mentioned above, which are open towards the outside in the radial direction.

Die eine in der Fig. 2 sichtbare Spannpratze 32 ist mit ausgezogenen Linien in einer Ruhestellung und mit strichpunktierten Linien in einer mit 32′ bezeichneten Arbeitsstellung dargestellt. Die Spannpratze 32 ist als ein, an einer am Halteelement 58 angeordneten Welle 60 schwenkbar gelagerter zweiarmiger Hebel ausgebildet. Die Achse der Welle 60 verläuft rechtwinklig zur Drehachse 52 und ist von dieser beabstandet. Es sei in diesem Zusammenhang erwähnt, dass beide in der Fig. 1 dargestellten Spannpratzen 32 an der einzigen gemeinsamen Welle 60 gelagert sind. Am gegen den Lagerbock 50 vorstehenden Arm der Spannpratze 32 ist eine Nase 62 angeformt, welche in Arbeitsstellung 32′ der Spannpratze 32 in einer Richtung parallel zu Drehachse 52 verläuft, dies ist mit 62′ angedeutet.One visible in FIG. 2 clamping claw 32 is shown with solid lines in a rest position and with dash-dotted lines in a working position designated 32 '. The clamping claw 32 is designed as a two-armed lever which is pivotably mounted on a shaft 60 arranged on the holding element 58. The axis of the shaft 60 is perpendicular to the axis of rotation 52 and is spaced from it. It should be mentioned in this connection that both clamping claws 32 shown in FIG. 1 are mounted on the single common shaft 60. On the protruding arm of the bracket 50 of the clamping claw 32, a nose 62 is formed, which in the working position 32 'of the clamping claw 32 extends in a direction parallel to the axis of rotation 52, this is indicated by 62'.

Am Lagerbock 50 ist eine oberhalb der Drehachse 52 verlaufende und coaxial zu dieser angeordnete Sicherheitskulisse 64 vorgesehen, welche in Richtung gegen das Halteelement 58 vorsteht und ein Zurückschwenken der Spannpratze 32 aus der Arbeitsstellung 32′ in die mit ausgezogenen Linien dargestellte Ruhelage 32 verhindert, sobald die Nase 62′ beim Drehen der Stützanordnung 12 um die Drehachse 52 in den Bereich der Sicherheitskulisse 64 kommt. Die Nase 62 bzw. 62′ ist in der oberen Endlage, in welcher sie mit der Sicherheitskulisse 64 zusammenwirkt noch einmal strichpunktiert angedeutet und mit 62˝ bezeichnet.On the bearing block 50 there is a one running above the axis of rotation 52 and coaxial to this arranged safety gate 64, which protrudes in the direction against the holding element 58 and a pivoting back of the clamping claw 32 from the working position 32 'in the rest position 32 shown with solid lines prevents as soon as the nose 62' when rotating the support assembly 12 around Axis of rotation 52 comes in the area of the security link 64. The nose 62 and 62 'is in the upper end position, in which it cooperates with the security backdrop 64 again indicated by dash-dotted lines and designated 62˝.

Die Spannpratze 32 ist im Endbereich des vom Lagerbock 50 entfernten Arms mit einer V-förmigen Nut 34 versehen. Bei der sich in Arbeitsstellung 32′ befindenden Spannpratze 32 ist die, mit 34′ bezeichnete V-förmige Nut 34 in radialer Richtung gesehen gegen aussen hin offen und in derselben, senkrecht zur Drehachse 52 verlaufenden Ebene angeordnet, in welcher auch die V-förmige Nut 34 der Aufnahmepratze 30 angeordnet ist. Wie auch in Fig. 1 gezeigt, sind die seitlich voneinander in Richtung der Achse der Welle 60 voneinander beabstandeten Spannpratzen 32 miteinander mittels der Abrollkulisse 40 wirkverbunden. Die Wirkungsweise dieser Abrollkulisse 40 ist weiter unten beschrieben.The clamping claw 32 is provided with a V-shaped groove 34 in the end region of the arm removed from the bearing block 50. When in the working position 32 'clamping claw 32, the 34' designated V-shaped groove 34 seen in the radial direction open towards the outside and arranged in the same, perpendicular to the axis of rotation 52 plane, in which the V-shaped groove 34 of the claw 30 is arranged. As also shown in FIG. 1, the clamping claws 32, which are laterally spaced apart in the direction of the axis of the shaft 60, are operatively connected to one another by means of the rolling link 40. The operation of this rolling link 40 is described below.

An den seitlich voneinander beanstandeten Aufnahmepratzen 30 ist eine weitere Welle 66 fixiert, deren Längsachse parallel zur Achse der Welle 60 verläuft. An dieser Welle 66 ist der Hebel 36 schwenkbar gelagert, welcher mit ausgezogenen Linien in Ruhestellung und strichpunktiert und mit 36′ bezeichnet in Arbeitsstellung dargestellt ist.A further shaft 66, the longitudinal axis of which runs parallel to the axis of the shaft 60, is fixed to the holding claws 30 which are laterally spaced apart. On this shaft 66, the lever 36 is pivotally mounted, which is shown with solid lines in the rest position and dash-dotted lines and designated 36 'in the working position.

Wie in dieser Fig. 2 gezeigt ist, wirkt die erste Feder 44 einerends auf den am Hebel 36 fixierten Stift 42 und andernends auf einen am Halteelement 58 fixierten weiteren Stift 68 ein. Diese erste Feder 44 spannt den Hebel 36 gegen die Ruhestellung vor, in welcher er an einem am Halteelement 58 angeordneten Anschlag 70 ansteht. Die zweite Feder 46, welche ebenfalls einerends am Stift 42 fixiert ist, ist andernends an einem an der Spannpratze 32 angeordneten weiteren Stift 72 befestigt. Die zweite Feder 46 spannt die Spannpratze 32 in Ruhestellung vor, in welcher sie am Hebel 36 ansteht. Die Wirkungslinien der beiden Federn 44 und 46 in Arbeitsstellung des Hebels 36 und der Spannpratze 32 sind mit strichpunktierten Linien angedeutet und mit 44′ bzw. 46′ bezeichnet.As shown in this FIG. 2, the first spring 44 acts on one end on the pin 42 fixed on the lever 36 and on the other end on a further pin 68 fixed on the holding element 58. This first spring 44 pretensions the lever 36 against the rest position, in which it rests on a stop 70 arranged on the holding element 58. The second spring 46, which is also fixed at one end to the pin 42, is attached at the other to a further pin 72 arranged on the clamping claw 32. The second spring 46 biases the clamping claw 32 in the rest position, in which it rests on the lever 36. The lines of action of the two springs 44 and 46 in the working position of the lever 36 and the clamping claw 32 are indicated by dash-dotted lines and denoted by 44 'and 46'.

Am freien Ende des Hebels 36 sind die beiden Walzen 38, von denen in der Fig. 2 nur eine sichtbar ist, drehbar gelagert. Beim Schwenken des Hebels 36 von der Ruhestellung im Gegenuhrzeigersinn in die mit 36′ bezeichnete Arbeitsstellung kommt die Walze 38 an einem mit 74 bezeichneten ersten Segment der Abrollbahn der Abrollkulisse 40 zur Anlage und schwenkt infolge ihrer Weiterbewegung die Spannpratze 32 aus derer Ruhestellung in die mit 32′ bezeichnete Arbeitsstellung im Uhrzeigersinn. Es ist zu beachten, dass in Arbeitsstellung 36′ der Hebel 36 ungefähr senkrecht auf einem zweiten Segment 76 der Abrollbahn der Abrollkulisse 40 steht. Der zwischen den beiden Segmenten 74, 76 vorhandene Knick in der Abrollbahn hat zur Folge, dass in einem ersten Bereich der Schwenkbewegung des Hebels 36 die Spannpratze 32 einen grossen Schwenkwinkel in Richtung zur Arbeitsstellung 32′ ausführt, und im nachfolgenden Schwenkbereich des Hebels 36 der Schwenkwinkel der Spannpratze 32 nur noch gering ist.At the free end of the lever 36, the two rollers 38, of which only one is visible in FIG. 2, are rotatably mounted. When pivoting the lever 36 from the rest position counterclockwise into the working position denoted by 36 ', the roller 38 comes into contact with a first segment of the rolling path 40 of the rolling link 40 designated by 74 and, as a result of its further movement, swivels the clamping claw 32 from its rest position to the position 32 'Designated working position clockwise. It should be noted that in the working position 36 ', the lever 36 is approximately perpendicular to a second segment 76 of the rolling path of the rolling link 40. The existing between the two segments 74, 76 kink in the rolling path has the result that in a first region of the pivoting movement of the lever 36, the clamping claw 32 executes a large pivoting angle in the direction of the working position 32 ', and in the subsequent pivoting range of the lever 36 the swivel angle of the clamping claw 32 is only small.

Die am Hebel 36 angeordneten Sicherheitsanschlagnocken 48, von welchen in der Fig. 2 ebenfalls nur einer sichtbar ist, begrenzen den Schwenkwinkel des Hebels 36, in dem die Sicherheitsanschlagnocken 48 mit ihrem freien oberen Ende an der Unterseite der Aufnahmepratzen 30 anschlagen, falls der Hebel 36 in die Arbeitsstellung geschwenkt wird, ohne dass ein Wickelkern 10 festgeklemmt wird.The safety stop cams 48 arranged on the lever 36, of which only one is also visible in FIG. 2, limit the pivoting angle of the lever 36 in which the safety stop cams 48 strike with their free upper end on the underside of the mounting claws 30 if the lever 36 is pivoted into the working position without a winding core 10 being clamped.

Zwischen dem Halteelement 58 und dem Hebel 36 ist ein aufblasbarer Balg 78 vorgesehen. Die Umrisskonturen des aufgeblasenen Balges 78 sind strichpunktiert angedeutet und mit 78′ bezeichnet. Der Hohlraum des Balges 78 ist durch eine zentrale Bohrung 80 im Halteelement 58 und im Flansch 56 sowie dem Innenraum der Hohlwelle 54 mit einer nicht dargestellten Druckquelle verbunden. Am Hebel 36 ist der Balg 78 mittels zweier Schraubenbolzen 82 fixiert, damit der Balg 78 im aufgeblasenen Zustand 78′ nicht gegen unten weggleiten kann.An inflatable bellows 78 is provided between the holding element 58 and the lever 36. The outline contours of the inflated bellows 78 are indicated by dash-dotted lines and designated 78 '. The cavity of the bellows 78 is connected to a pressure source, not shown, through a central bore 80 in the holding element 58 and in the flange 56 and the interior of the hollow shaft 54. On the lever 36, the bellows 78 is fixed by means of two screw bolts 82, so that the bellows 78 in the inflated state 78 'cannot slide away towards the bottom.

Auf der Tragfläche 16 des Wickelkerns 10 ist der Wickel 18 aufgewickelt. Wie in dieser Fig. 2 besonders gut sichtbar, ist der nach der innenliegenden Seite vorstehende umlaufende Steg 24 an seinem freien Ende als V-förmiger Keil 26 ausgebildet. Im Keil 24 ist eine gegen die Aussenseite des Wickelkerns 10 hin offene umlaufende Nut 84 vorgesehen. In der Nut 84 ist ein Teil des Wickelbandes 22 aufgewickelt, welcher nicht für die Bildung des Wickels 18 benötigt wird. Wie weiter oben beschrieben, ist das eine Ende des Wickelbandes 22 am Boden der Nut 84 am Wickelkörper 10 befestigt. Bei leerem Wickelkern 10 ist das ganze Wickelband 22 in er Nut 84 aufgewickelt.The winding 18 is wound on the supporting surface 16 of the winding core 10. As can be seen particularly well in this FIG. 2, the circumferential web 24 projecting towards the inner side is designed as a V-shaped wedge 26 at its free end. Provided in the wedge 24 is a circumferential groove 84 which is open towards the outside of the winding core 10. Part of the winding tape 22 is wound in the groove 84 and is not required for the formation of the winding 18. As described above, one end of the winding tape 22 is attached to the bottom of the groove 84 on the winding body 10. When the winding core 10 is empty, the entire winding tape 22 is wound in the groove 84.

Im Bereich der Tragfläche 16 ist die Nut 84 verbreitert, so dass sie zwei voneinander beabstandete Ausnehmungen 86 bildet, in welchen je eine umlaufende Führung 88 angeordnet ist. In den Führungen 88 ist eine ringförmige Abdekkung 90 gleitend gelagert, welche einen parallel zur Längsachse des Wickelkerns 10 verlaufenden Schlitz für den Austritt des Wickelbandes 22 aus der Nut 84 aufweist. Der Schwerpunkt S des Wickelkerns 10 bzw. des darauf aufgewickelten Wickels 18 liegt in der quer zur Drehachse 52 verlaufenden Ebene, in welcher die V-förmigen Nuten 34 bzw. 34′ angeordnet sind.In the area of the wing 16, the groove 84 is widened so that it forms two spaced-apart recesses 86, in each of which a circumferential guide 88 is arranged. An annular cover 90 is slidably mounted in the guides 88 and has a slot running parallel to the longitudinal axis of the winding core 10 for the exit of the winding tape 22 from the groove 84. The center of gravity S of the winding core 10 or the winding 18 wound thereon lies in the plane running transversely to the axis of rotation 52, in which the V-shaped grooves 34 and 34 'are arranged.

In der Fig. 2 ist ein Ausleger 92 eines nicht weiter dargestellten Handlinggerätes, beispielsweise eines Stapelfahrzeuges, teilweise geschnitten dargestellt. Das freie Ende des Auslegers 92 weist eine V-förmige Aufnahmenut 94 für den V-förmigen Keil 26 des Wickelkerns 10 auf. Der Ausleger 92 liegt zwischen den beiden seitlich voneinander beabstandeten Aufnahmepratzen 30 am Steg 24 des Wickelkerns 10 an und ist mittels des Handlinggerätes in einer Richtung parallel zur Drehachse 52 und quer dazu verschiebbar.2, a boom 92 of a handling device, not shown, for example a stacking vehicle, is shown partially in section. The free end of the arm 92 has a V-shaped receiving groove 94 for the V-shaped wedge 26 of the winding core 10. The cantilever 92 lies between the two laterally spaced receiving claws 30 on the web 24 of the winding core 10 and can be moved in a direction parallel to the axis of rotation 52 and transversely thereto by means of the handling device.

Die Vorrichtung zum drehbaren Lagern des hohlzylindrischen Wickelkerns 10 funktioniert wie folgt. Bevor ein Wickelkern 10 auf die Aufnahmepratzen 30 zur Anlage gebracht werden kann, ist die Stützanordnung 12 in die in den Fig. 1 und 2 dargestellte Lage zu bringen, in welcher die beiden Aufnahmepratzen 30 oben liegen. Der Balg 78 ist gegenüber der Umgebungsluft drucklos, so dass sich der Hebel 36 und die Spannpratzen 32 infolge der Zugkraft der beiden Federn 44, 46 in Ruhestellung befinden. Mittels des Handlinggerätes wird ein Wickelkern 10 auf die Aufnahmepratzen 30 zur Auflage gebracht, in dem der Ausleger 92 zwischen die beiden Spannpratzen 30 eingefahren und anschliessend abgesenkt wird, so dass der Keil 26 in die Nuten 34 der Aufnahmepratzen 30 zu liegen kommt. Die V-förmige Ausbildung des Steges 24 sowie der Nuten 34 garantiert dabei eine sichere Aufnahme und Zentrierung des Wickelkerns 10, auch bei nicht genau positioniertem Ausleger 92. Sobald der Keil 26 des Steges 24 in den Nuten 34 sitzt, kann der Ausleger 92 weiter abgesenkt und in einer Richtung parallel zur Drehachse 52 weggefahren werden. Da der Schwerpunkt S des Wickelkerns 10 in derselben Ebene liegt, in welche auch die Nuten 34 angeordnet sind, fällt die Längsachse des Wickelkerns 10 mit der Drehachse 52 zusammen. Nun wird der Balg 78 mit der Druckquelle verbunden und aufgeblasen, was die Schwenkbewegung des Hebels 36 im Gegenuhrzeigersinn hervorruft. Dabei kommen die Walzen 38 am ersten Segment 74 zur Anlage, was bei der Weiterbewegung des Hebels 36 ein Verschwenken der Spannpratzen 32 im Uhrzeigersinn zur Folge hat, bis diese am V-förmigen Keil 26 des Wickelkerns 10 zur Anlage kommen. Da der Winkel zwischen dem zweiten Segment 76 der Abrollbahn der Abrollkulisse 40 und dem Hebel 36 nahezu 90° beträgt, werden die Spannpratzen 32 auch mit einem relativ kleinen Ueberdruck im Balg 78 mit sehr grosser Kraft gegen den Steg 24 gepresst, was ein sicheres Festklemmen des Wickelkerns 10 an der Stützanordnung 12 zur Folge hat. Es ist zu beachten, dass bei aufgesetztem Wickelkern 10 der Schwenkbereich des Hebels 36 durch das Segment 76 begrenzt wird und die Sicherheitsanschlagnocken nicht an den Aufnahmepratzen 30 anliegen.The device for rotatably supporting the hollow cylindrical winding core 10 functions as follows. Before a winding core 10 can be brought into contact with the locating claws 30, the support arrangement 12 must be brought into the position shown in FIGS. 1 and 2, in which the two locating claws 30 lie on top. The bellows 78 is depressurized with respect to the ambient air, so that the lever 36 and the clamping claws 32 are in the rest position due to the tensile force of the two springs 44, 46. Means of the handling device, a winding core 10 is brought to rest on the holding claws 30, in which the arm 92 is inserted between the two clamping claws 30 and then lowered, so that the wedge 26 comes to rest in the grooves 34 of the holding claws 30. The V-shaped design of the web 24 and the grooves 34 guarantees a secure reception and centering of the winding core 10, even when the arm 92 is not positioned precisely. As soon as the wedge 26 of the web 24 is seated in the grooves 34, the arm 92 can be lowered further and moved away in a direction parallel to the axis of rotation 52. Since the center of gravity S of the winding core 10 lies in the same plane in which the grooves 34 are also arranged, the longitudinal axis of the winding core 10 coincides with the axis of rotation 52. The bellows 78 is now connected to the pressure source and inflated, which causes the pivoting movement of the lever 36 in the counterclockwise direction. The rollers 38 come to rest on the first segment 74, which, when the lever 36 moves further, causes the claws 32 to pivot clockwise until they come to rest on the V-shaped wedge 26 of the winding core 10. Since the angle between the second segment 76 of the rolling path of the rolling link 40 and the lever 36 is almost 90 °, the clamping claws 32 are also pressed with a relatively small overpressure in the bellows 78 with a very great force against the web 24, which securely clamps the Winding core 10 on the support assembly 12 results. It should be noted that when the winding core 10 is in place, the pivoting range of the lever 36 is limited by the segment 76 and the safety stop cams do not rest on the mounting claws 30.

Beim Drehen der Stützanordnung 12 um die Drehachse 52 wird somit der Wickelkern 10 zwingend mitgenommen. Beim Drehen müssen folglich abwechslungsweise die Aufnahmepratzen 30 und die Spannpratzen 32 das Gewicht des Wickelkerns 10 und des darauf eventuell aufgewickelten Wickels 18 übernehmen. Da, wie schon weiter oben erwähnt der Hebel 36 nahezu senkrecht auf dem zweiten Segment 76 der Abrollkulisse 40 steht, wird der Hebel 36 dabei auf Druck beansprucht und die Rückwirkung auf dem Balg 78 vernachlässigbar klein. Um dennoch sicherzustellen, dass bei einem unvorhergesehenen Druckverlust im Balg 78 der Wickel 10 an der Stützanordnung 12 sicherfest geklemmt bleibt, läuft die Nase 62 jeweils im Bereich der Sicherheitskulisse 64 vorbei, sobald die Spannpratzen 32 einen erheblichen Anteil des Gewichtes des Wickels 10 und des darauf aufgewickelten Wickels 18 übernehmen müssen. Es ist einleuchtend, dass, bei sich in Arbeitsstellung 32′ befindenden Spannspratzen 32, zwischen den Nasen 62′ und der Sicherheitskulisse 64 ein Luftspalt vorgesehen ist, und die Nasen 62′ nur an der Sicherheitskulisse 64 gleiten, falls ein Druckverlust in dem Balg 78 auftreten sollte.When the support arrangement 12 is rotated about the axis of rotation 52, the winding core 10 is thus entrained. As a result, when rotating, the holding claws 30 and the clamping claws 32 have to take over the weight of the winding core 10 and the roll 18 possibly wound thereon. Since, as already mentioned above, the lever 36 is almost perpendicular to the second segment 76 of the rolling link 40, the lever 36 is subjected to pressure and the reaction on the bellows 78 is negligibly small. In order to ensure that, in the event of an unforeseen pressure loss in the bellows 78, the winding 10 remains securely clamped on the support arrangement 12, the nose 62 runs past in the area of the safety link 64 as soon as the clamping claws 32 have a considerable proportion of the weight of the winding 10 and of the weight thereon wound winding 18 must take over. It is obvious that, when the clamping claw 32 is in the working position 32 ', an air gap is provided between the lugs 62' and the safety link 64, and the lugs 62 'only slide on the safety link 64 if there is a pressure loss in the bellows 78 should.

Sobald der Wickelvorgang beendet ist, wird die Drehung um die Drehachse 52 gebremst, und die Stützanordnung 12 in die in den Fig. 1 und 2 gezeigte Lage gedreht, in welcher die beiden Aufnahmepratzen 30 oben liegen. Durch Abblasen der Luft aus dem Balg 78 werden nun der Hebel 36 und die Spannpratzen 32 infolge der Kraft der beiden Federn 44, 46 in die Ruhestellung zurück geschwenkt. Der Wickelkern 10 ist nun frei und kann mittels des Auslegers 92 des Handlinggerätes von der Stützanordnung 10 entfernt werden. Die Vorrichtung ist nun für die erneute Aufnahme eines weiteren Wickelkerns 10 bereit.As soon as the winding process has ended, the rotation about the axis of rotation 52 is braked and the support arrangement 12 is rotated into the position shown in FIGS. 1 and 2, in which the two locating claws 30 are located at the top. By blowing the air out of the bellows 78, the lever 36 and the clamping claws 32 are pivoted back into the rest position due to the force of the two springs 44, 46. The winding core 10 is now free and can be removed from the support arrangement 10 by means of the extension 92 of the handling device. The device is now ready to receive another winding core 10.

Die weiter oben beschriebene Vorrichtung zum drehbaren Lagern eines hohlzylindrischen Wickelkerns 10 eignet sich besonders für Wickelstationen, wie sie beispielsweise in der schon weiter oben erwähnten EP-OS 0 236 561 beschrieben sind. Beim Aufwickeln eines beispielsweise in einer Schuppenformation anfallenden Stromes von Druckereiprodukten 20 wird wie folgt vorgegangen: Ein leerer Wickelkern 10 wird, wie weiter oben beschrieben, auf die Aufnahmepratzen 30 aufgelegt und mittels der Spannpratzen 32 an der Stützanordnung 12 festgeklemmt. Das aussenliegende freie Ende des Wickelbandes 22 wird an einer Bandspule befestigt, wie dies in der oben erwähnten EP-OS näher beschrieben ist. Durch Drehen der Bandspule wird Wickelband 22 ab dem in der Nut 84 aufgewickelten Vorrat des Wickelbandes 22 abgewickelt. Dabei wird die Hohlwelle 54 leicht gebremst, damit das Wickelband 22 satt auf die Bandspule aufgewickelt werden kann. Beim Abwickeln des Wickelbandes 22 ab dem Wickelkern 10 dreht sich dieser selbstverständlich um die Drehachse 52, während die Abdeckung 90 bezüglich der Umgebung stillsteht aber sich relativ zum Wickelkern 10 in den Führungen 88 verschiebt, so dass der in der Abdeckung 90 angeordnete Schlitz für das Wickelband 22 am selben Ort stehen bleibt. Sobald genügend Wickelband 22 für den zu bildenden Wickel 18 vom Wickelkern 10 abgewickelt und auf die Bandspule aufgewickelt worden ist, wird die Hohlwelle 54 und somit die Stützanordnung 12 und der Wickelkern 10 im Aufwickelsinn angetrieben. Die zugeführten Druckereiprodukte 20 werden so dann zusammen mit dem nun von der Bandspule abgewickelten Wickelband 22 auf den Wickelkern 10 aufgewickelt. Dabei ist zu beachten, dass die Tragfläche 16 zusammen mit der Abdeckung 90 eine Zylinderfläche bilden. Sobald genügend Druckereiprodukte 20 zu einem Wickel 18 aufgewickelt sind, wird das Wickelband 22 noch um eine volle Umdrehung um den fertigen Wickel 18 geführt und dessen freies Ende mit dem Wickelband 22 verbunden, so dass ein freitragender Wickel gebildet ist, wie dies in der Fig. 1 dargestellt ist. Der Wickelkern 10 kann nun zusammen mit dem Wickel 18 mittels des Handlinggerätes von der Stützanordnung 12, wie diese weiter oben beschrieben ist, abgehoben werden.The device described above for rotatably supporting a hollow cylindrical winding core 10 is particularly suitable for winding stations, such as are described, for example, in EP-OS 0 236 561 already mentioned above. When winding up a stream of printed products 20, for example occurring in a scale formation, the procedure is as follows: An empty winding core 10, as described above, is placed on the receiving claws 30 and clamped to the support arrangement 12 by means of the clamping claws 32. The outer free end of the winding tape 22 is attached to a tape reel, as described in more detail in the above-mentioned EP-OS. By turning the tape reel, winding tape 22 is unwound from the supply of winding tape 22 wound in the groove 84. The hollow shaft 54 is braked slightly so that the winding tape 22 can be wound up onto the tape reel. When the winding tape 22 is unwound from the winding core 10, this of course rotates about the axis of rotation 52, while the cover 90 remains stationary with respect to the surroundings but moves relative to the winding core 10 in the guides 88, so that the slot arranged in the cover 90 for the winding tape 22 remains in the same place. As soon as enough winding tape 22 for the winding 18 to be formed has been unwound from the winding core 10 and wound onto the tape reel, the hollow shaft 54 and thus the support arrangement 12 and the winding core 10 are driven in the winding direction. The supplied printed products 20 are then unwound together with the now from the tape reel Winding tape 22 wound on the winding core 10. It should be noted that the wing 16 together with the cover 90 form a cylindrical surface. As soon as enough printed products 20 have been wound up to form a winding 18, the winding band 22 is guided through the finished winding 18 by a full revolution and its free end is connected to the winding band 22, so that a self-supporting winding is formed, as shown in FIG. 1 is shown. The winding core 10 can now be lifted together with the winding 18 by means of the handling device from the support arrangement 12, as described above.

Selbstverständlich kann die Vorrichtung auch zum Abwickeln von Druckereiprodukten 20 ab einem Wickel 18 eingesetzt werden. So wird der Wickelkern 10 mit dem Wickel 18 auf die Stützanordnung 12 aufgesetzt und an diese festgeklemmt. Durch Abziehen des Wickelbandes 22 wird die Stützanordnung 12 im Abwickelsinn in Drehung versetzt, und die Druckprodukte 20 lösen sich vom Wickel 18 in bekannter Art und Weise ab. Sobald alle Druckereiprodukte 20 vom Wickel 18 abgewickelt sind, wird die Stützanordnung 12 abgebremst und im Aufwickelsinn angetrieben, so dass nun das Wickelband 22 wieder zu einem Vorrat in der Nut 84 auf den Wickelkern 10 aufgewickelt wird.Of course, the device can also be used for unwinding printed products 20 from a roll 18. Thus, the winding core 10 with the winding 18 is placed on the support arrangement 12 and clamped onto it. By pulling the winding tape 22, the support assembly 12 is rotated in the unwinding direction, and the printed products 20 detach from the winding 18 in a known manner. As soon as all printed products 20 have been unwound from the winding 18, the support arrangement 12 is braked and driven in the winding direction, so that the winding tape 22 is now wound up again onto a supply in the groove 84 on the winding core 10.

Es ist auch möglich, dass am Steg 24 des Wickelkerns 10 eine vorzugsweise V-förmige Nut angeordnet ist, welche auf an den Aufnahmepratzen 30 und Spannpratzen 32 ausgebildete ebenfalls vorzusweise V-förmige Keile zur Anlage bringbar sind. Es ist auch möglich, dass zwei Aufnahmepratzen 30 und eine einzige Spannpratze 32 vorgesehen ist, wobei diese eine Spannpratze 32 vorzugsweise in einer Symmetrieebene angeordnet ist, in welcher die Drehachse 52 liegt und zu welcher die beiden Aufnahmepratzen 32 symmetrisch angeordnet sind. Bevorzugterweise sind in diesem Fall die beiden Aufnahmepratzen 30 und die einzige Spannpratze 32 in einem gleichseitigen Dreieck angeordnet. Es ist aber auch denkbar, dass nur eine einzige Aufnahmepratze 30 und eine einzige Spannpratze 32 vorgesehen sind. Die beiden Pratzen würden dann diametral einander gegenüberliegen und vorzugsweise breit ausgebildet sein, um über einen grösseren Bereich in Umfangsrichtung am Steg 24 des Wickelkerns 10 anzuliegen.It is also possible for a preferably V-shaped groove to be arranged on the web 24 of the winding core 10, which groove can also be brought into contact with V-shaped wedges which are also preferably formed on the mounting claws 30 and clamping claws 32. It is also possible for two holding claws 30 and a single clamping claw 32 to be provided is, this a clamping claw 32 is preferably arranged in a plane of symmetry in which the axis of rotation 52 lies and to which the two mounting claws 32 are arranged symmetrically. In this case, the two holding claws 30 and the single clamping claw 32 are preferably arranged in an equilateral triangle. However, it is also conceivable that only a single mounting claw 30 and a single clamping claw 32 are provided. The two claws would then lie diametrically opposite one another and would preferably be of wide design in order to lie against the web 24 of the winding core 10 over a larger area in the circumferential direction.

Es ist auch einzusehen, dass das Andrückelement bzw. die Spannpratzen 32 nicht zwingend schwenkbar gelagert sein müssen, so können sie auch beispielsweise in radialer Richtung schiebbar sein. Schlussendlich wäre es auch noch denkbar, dass das Stützelement und das Andrückelement schiebbar und/oder schwenkbar gelagert sind.It can also be seen that the pressing element or the clamping claws 32 do not necessarily have to be pivotally mounted, so that they can also be pushed in the radial direction, for example. Finally, it would also be conceivable for the support element and the pressure element to be slidably and / or pivotably mounted.
