Abstract

A device for arresting paper, board, film or similar material rolls having touch-sensitive surfaces between the carrier arms of unwind devices or roll changers, as are used, for example, on rotary printing machines for the changing of expired rolls for full rolls at full machine running speed and in which the rolls are carried by power-actuated trunnions, which are driven into the winder cores of the roll, is designed in such a way that, power-actuated clamping elements (6) which arrest the roll (4) on its end faces are arranged on the carrier arms (2) of the unwind device (1) and axially parallel to the power-actuated trunnions (5). In this case, the clamping elements (6) are pressed onto the end faces of the roll (4) in such a way, that no forces effecting a displacement of the roll (4) are transmitted to the outer layers of the roll (4). <IMAGE>

Description

Die Erfindung betrifft nach dem Oberbegriff des Patentanspruches 1 eine Vorrichtung, die das beschädigungsfreie Einspannen von Papier, Plastik, Gewebe oder ähnlichen Materialien, die auf Hülsen aufgewickelt sind und die zum Zweck der Weiterverarbeitung in Abwickelvorrichtungen oder auch sogenannten Rollenwechslern eingespannt werden.According to the preamble of claim 1, the invention relates to a device which is used for the damage-free clamping of paper, plastic, tissue or similar materials which are wound on sleeves and for the purpose of further processing can be clamped in unwinding devices or so-called reel changers.

Solche Abwickelvorrichtungen oder Rollenwechsler, wie sie vornehmlich in der Druckindustrie verwendet werden, sind in der Regel mit zwei Tragarmen ausgerüstet, die auf einer horizontal drehbaren Welle angeordnet sind und an beiden Tragarmenden kraftbetätigte Tragzapfen aufweisen, die zum Zweck der Aufnahme der Rollen in die Wickelhülsen der Rollen eingefahren werden.Such unwinding devices or reel changers, as they are primarily used in the printing industry, are usually equipped with two support arms, which are arranged on a horizontally rotatable shaft and have power-operated support pins on both support arm ends, which are used for the purpose of accommodating the rolls in the winding tubes of the Rolls are retracted.

Die Rollen werden durch geeignete Fördersysteme zwischen die Tragzapfen der Abwickelvorrichtung oder Rollenwechsler transportiert und so positioniert, daß die Drehachse der Rollen mit den Drehachsen der Tragzapfen deckungsgleich sind.
Durch ungenaues Positionieren der Rollen durch die Förderanlage oder durch asymmetrische Geometrie der Rolle selber oder exzentrischer Lage der Wickelhülse ist es sehr oft aber nicht möglich, die Achsparallelität herzustellen, was zur Folge hat, daß die Tragzapfen nicht berührungsfrei in die Wickelhülse einfahren können, wodurch Axialkräfte auf die Rolle übertragen werden. Das führt zu Verschiebungen und Beschädigungen der äußeren Wickellagen der Papierrollen.The rollers are transported by suitable conveyor systems between the trunnions of the unwinder or reel changer and positioned so that the axis of rotation of the rollers are congruent with the axes of rotation of the trunnions.
Due to inaccurate positioning of the rolls by the conveyor system or due to asymmetrical geometry of the roll itself or the eccentric position of the winding tube, it is very often not possible to create parallel axes, which means that the trunnions cannot move into the winding tube without contact, which means axial forces on the role will be transferred. This leads to displacements and damage to the outer winding layers of the paper rolls.

Vornehmlich in Zeitungs-Akzidenz- und Tiefdruckbetrieben erfolgt die Zufuhr und das Einspannen der Papierrollen, als auch der Wechsel zwischen abgelaufener und Vollrolle vollautomatisch bei voller Maschinenlaufgeschwindigkeit, wobei die beiden Papierbahnen durch Klebung und geeignete Trennvorrichtungen miteinander verbunden werden.Mainly in newspaper commercial and gravure printing companies, the feeding and clamping of the paper rolls, as well as the change between expired and full rolls takes place fully automatically at full machine speed, whereby the two paper webs are connected to each other by gluing and suitable separating devices.

Zu diesem Zweck werden die zu einer Spitze oder auch gerade geschnittenen Enden der Papierrolle mit dünnen, Sollreißstellen aufweisenden Klebestreifen auf der Rolle fixiert und mit doppelseitigen Klebebändern versehen, mit der die in die Abrollvorrichtung eingespannte Rolle während dem Lauf der Rotations-Druckmaschine an die zweite, in der Abrollvorrichtung eingespannte und ablaufende Rolle bei voller Maschinen-Betriebsgeschwindigkeit durch Klebung verbunden wird, sobald die ablaufende Rolle bis auf einen geringen Rest von der Wickelhülse abgelaufen ist.For this purpose, the ends of the paper roll, which are cut to a point or straight, are fixed on the roll with thin adhesive strips having predetermined tear points and provided with double-sided adhesive tapes with which the roll clamped in the unwinding device is attached to the second, while the rotary printing press is running. the roll clamped in the unwinding device and running at full machine operating speed is connected by adhesive as soon as the running roll has run off the winding tube except for a small amount.

Wird aber durch die geschilderte Kraftwirkung beim Einfahren der Tragzapfen in die Wickelhülse einer Rolle die äußere Lage der Papierrolle beschädigt, ist ein einwandfreier Klebevorgang nicht mehr zu gewährleisten und die mangelhaft geklebte Papierbahn reißt, was wiederum einen Stillstand der Rotations-Druckmaschine zur Folge hat, mit dem Betriebs- und Materialverluste verbunden sind.However, if the external force of the paper roll is damaged by the described force effect when the trunnion is inserted into the winding tube of a roll, a perfect gluing process can no longer be guaranteed and the poorly glued paper web tears, which in turn causes the rotary printing press to come to a standstill which are associated with operating and material losses.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Vorrichtung gemäß dem Oberbegriff des Patentanspruches 1 zu schaffen, die ein sicheres Aufnehmen und Halten von Tragrollen ohne Beschädigung des auf der Rolle befindlichen Papieres oder dgl. ermöglicht und mit geringem technisch-ökonomischen Aufwand realisierbar ist.The invention is therefore based on the object to provide a device according to the preamble of claim 1, which enables a safe mounting and holding of idlers without damaging the paper on the roll or the like. And can be realized with little technical-economic effort.

Die Aufgabe löst eine Vorrichtung nach dem Patentanspruch 1 durch ihre kennzeichnenden Merkmale. Die Unteransprüche 2 bis 6 offenbaren vorteilhafte Weiterbildungen und Ausgestaltungen der erfindungsgemäßen Vorrichtung.The object is achieved by a device according to claim 1 by its characterizing features. The sub-claims 2 to 6 disclose advantageous developments and refinements of the device according to the invention.

Durch die Erfindung wird ein sicheres Aufnehmen und Halten der Tragrolle gewährleistet, ohne das auf ihr befindliche Papier oder dgl. Materalien zu beschädigen. Damit wird der Produktionsablauf der besagten Maschine/Anlage in keiner Weise gefährdet bzw. gestört.The invention ensures that the support roller is securely picked up and held without damaging the paper or the like on it. This means that the production process of the said machine / system is in no way endangered or disrupted.

Die Weiterbildungen und Ausgestaltungen der Vorrichtung gemäß den Unteransprüchen sind auf eine weitere Erhöhung der Effektivität gerichtet.The developments and refinements of the device according to the subclaims are aimed at a further increase in effectiveness.

Dabei bedeutet 1 eine Abwickelvorrichtung oder einen Rollenwechsler, in dem zwei gegenüberliegende Tragarme 2 mit einer Welle 3 drehbar gelagert sind. Eine Papierrolle 4 ist mittels einer nicht weiter gezeigten Fördereinrichtung zwischen die in den Tragarmen 2 angeordneten und hier noch eingezogenen Tragzapfen 5 gebracht. Oberhalb der Tragzapfen 5, also von diesen in Richtung der Welle 3 gesehen, befinden sich an den Tragarmen 2 jeweils ein kraftbetätigtes Spannelement 6, desen Spannplatte 7 der Papierrolle 4 zugewandt ist. Die Tragarme 2 sind hier vorzugsweise zur Aufnahme von zwei Tragrollen mit der entsprechenden Anzahl von Elementen 5, 6, 7 versehen ausgebildet.The device for locking rollers with touch-sensitive surfaces in a rolling device is shown in Fig. 1 in a plan view. 1 means an unwinder or a reel changer in which two opposite support arms 2 are rotatably mounted with a shaft 3. A paper roll 4 is brought by means of a conveyor device, not shown, between the support pins 5 which are arranged in the support arms 2 and are still drawn in here. Above the support pins 5, that is to say seen from them in the direction of the shaft 3, there are in each case on the support arms 2 a power-operated tensioning element 6, the tensioning plate 7 of which faces the paper roll 4. The support arms 2 are preferably designed to accommodate two support rollers with the corresponding number of elements 5, 6, 7.

Die Spannplatten 7 der Spannvorrichtung 6 sind in der Fig. 2 gegen die Stirnseiten der Papierrolle 4 gefahren und haben diese durch in die Spannplatten 7 eingebaute Sensoren gesteuert, so eingespannt, daß keine Kräfte auf die äußere Lage der für die automatische Kleberverbindung vorbereitete Papierrolle übertragen werden. Damit ist die Rolle 4 in ihrer momentanen Lage fixiert. Die Tragzapfen 5 der Abwickelvorrichtung 1 oder des Rollenwechslers sind noch nicht in die Wickelhülse der Papierrolle 4 eingefahren.The clamping plates 7 of the clamping device 6 are moved in FIG. 2 against the end faces of the paper roll 4 and have controlled them by sensors built into the clamping plates 7, so clamped that no forces are transmitted to the outer layer of the paper roll prepared for the automatic adhesive connection . The roller 4 is thus fixed in its current position. The trunnions 5 the unwinding device 1 or the reel changer have not yet moved into the winding tube of the paper reel 4.

Die Fig. 3 zeigt die Situation nach dem Einfahren der Tragzapfen 5 in die Wickelhülse der Papierrolle 4, die damit in die Abrollvorrichtung 1 oder den Rollenwechsler eingeachst ist. Die Spannelemente 6 haben die Rolle 4 dabei in ihrer Lage fixiert. FIG. 3 shows the situation after the support pins 5 have been moved into the winding tube of the paper roll 4, which is thus inserted into the unwinding device 1 or the roll changer. The tensioning elements 6 have fixed the roller 4 in its position.

Der Zustand nach dem erfolgten Einfahren der Tragzapfen 5 in die Wickelhülse der Papierrolle und die zurückgezogenen Spannplatten 7 der Spannelemente 6 ist aus Fig. 4 ersichtlich. Die eingeachste Papierrolle 4 ist zum Ankleben an die ablaufende Papierbahn bereit.The state after the support pins 5 have been retracted into the winding tube of the paper roll and the retracted clamping plates 7 of the clamping elements 6 can be seen from FIG. 4 . The inserted paper roll 4 is ready to be glued to the running paper web.

In der Fig. 5 ist ein vorteilhaftes Detail der Spannplatte 7 der Spannelemente 6 dargestellt. Diese Spannplatte 7, die kraftbetätigt gegen eine Stirnseite der Papierrolle 4 gedrückt wird, ist auf einer Kolbenstange 9 der Spannelemente 6 radial beweglich angeordnet. Geeignete Federelemente 8 ermöglichen das Ausweichen der Spannplatten 7 beim Auftreten von Radialkräften und das Zurückführen derselben in die zentrische Anfangslage nach dem Wegfall der Radialkräfte. 5 shows an advantageous detail of the clamping plate 7 of the clamping elements 6. This clamping plate 7, which is pressed by force against an end face of the paper roll 4, is arranged on a piston rod 9 of the clamping elements 6 so as to be radially movable. Suitable spring elements 8 allow the clamping plates 7 to escape when Occurrence of radial forces and returning them to the central initial position after the radial forces cease to exist.
