Definitions
- the invention relates to a roller for guiding and stretching tapes and / or film webs for winding devices, preferably for devices for the continuous vapor deposition or sputtering of plastic or paper tapes and webs in a vacuum, with a large number of rolling element bearings arranged one behind the other on the roller axis
- Outer bushes of the same configuration which are rotatably held on the roller axis via rolling elements, the outer bushes being held in a contact-free manner and at a distance from one another, and the film strip or film web partially wrapping around the outer bushes and thereby being preloaded on parts of the cylindrical surface of the outer bushings.
- a stretching and upsetting roller for sheets or webs made of flexible material is known (DE-PS 892 286), which has a curved path between the end sections and which can be clamped - adjustable in any plane with the bent axis of the roller.
- Such Stretching and upsetting rollers are provided with an elastic hose made of textile material, which is pulled over the individual roller sections and thus ensures that the roller sections run continuously.
- This known roller has the disadvantage, among other things, that experience has shown that it is highly electrostatically charged, which is not acceptable for a sputtering device in a winding device.
- roller 40 25 232.9 is a roller for guiding and stretching strips and / or film webs for winding devices, preferably for devices for the continuous vapor deposition or sputtering of plastic strips and webs in a vacuum, in which a large number of consecutive ones on the roller axis arranged, in the manner of axial cylindrical roller bearings on the axis via rolling elements rotatably guided outer bushing of the same configuration are provided, the outer bushings are kept in contact-free distance from each other and the film strip or film web partially wraps around the outer bushings and thereby with pre-tension on parts of the cylindrical surface of the outer bushings is present.
- the present invention has for its object to provide a roller of the type in question, which is inexpensive to manufacture, the synchronization of which is particularly precise, which generates low noise, which enables high speeds while avoiding a special lubrication system, and also maintains its properties under the conditions of a high vacuum, i.e., for example, does not contain any parts that are made of materials that tend to outgas and thus become brittle.
- a high vacuum i.e., for example, does not contain any parts that are made of materials that tend to outgas and thus become brittle.
- either the entire roller and / or the segments interacting directly with the film can be adjustable during operation, so that the film can be pulled straight and smooth at any moment.
- At least one longitudinally displaceably held and guided profile rod in a longitudinal groove of the roll axis which cooperates with pins or ball pins which are held in the receptacle bushes assigned to the outer bushings or are formed integrally therewith and radially inwards up to extend into recesses which are arranged on the profile bar at intervals, a longitudinal displacement of the profile bar pivoting the receptacles which are tiltably mounted on the roller axis relative to the longitudinal axis of the roller axis.
- the bushings arranged on the right and left of the center on the roller axis are pivoted transversely to the shaft axis. These pivotable bushings are adjustable in their angularity to the longitudinal axis of the roll so that, depending on the quality of the film, spreading or stretching can be achieved.
- the gap between the individual segments or bushings is expediently chosen so that it does not affect the spreading process.
- this straight spreader roll which has no arching, the distance to the next roll can be very small, which in turn leads to a small space requirement.
- the straight, manually angle-adjustable metallic spreader roller is divided into rotatable segments or bushings 2, the middle fixed bushing 1 always being transverse or at right angles to the center of the web.
- the remaining pivoted bushings 2 are arranged to the right or left of the center of the web so that they are continuously at a certain angle to the central axis or line.
- a possible variant of this arrangement consists in that a part of the bushes 2 is adjusted from the center at a smaller angle and the edge segments or the bushings 2 are pivoted more strongly in their angularity at the two ends of the roller axis 4.
- the adjustment (change in angle) of the pivotably mounted bushings 2 is accomplished with a displaceable profile rod 18, which is arranged on the left and right from the center and is held in a groove 17.
- an adjusting drive 20 with a rotatable spindle and a pitch of z. B. 0.5 mm and with an additional locking device.
- the adjusting drive 20 is on the one hand firmly connected to the receiving shaft 4, and on the other hand clamped on the two displaceable profile bars. Before installing bushings 2, make sure that the adjustment drive is in the zero position and locked. With this arrangement, the angular adjustment accuracy of the bushings can be approx. 0.2 degrees per 1/4 turn of the adjusting drive.
- the drive must have a negative position before assembly.
- This manually angle-adjustable metallic spreader roller takes place via two end shields 3 which enclose the end journals 5 of the receiving shaft 4 and which in turn are pivotably attached to the machine frame in order to bring about a change in the wrap angle.
- a scaled handwheel 6 with a lock or a motor 7 is provided for changing the wrap.
- the middle fixed bushing consists of a receiving bushing 8 which is fixedly attached to the receiving shaft 4 by means of snap rings 9. Furthermore, two smooth-running ball bearings 10, which are fastened with snap rings 11, are arranged on the receiving bushing 8. Before installing these bearings, make sure that they are vacuum-pumped beforehand to prevent grease escaping during the process. At the head of the low-friction ball bearing 10 is the outer bush 12, which is held by the two low-friction bearings 10 due to its special geometry. This geometry of the bushing 12 or the shoulders 25 practically precludes an imbalance (rotationally symmetrical part).
- the remaining bushes 2 (FIG. 5) attached on both sides of the middle fixed bushing 1 are all pivotally mounted on the receiving shaft 4.
- each segment consists of a receiving bushing 8, which is supported by means of two drill bushings 13 and two balls 14 in counterbores 22 of the receiving shaft 4 without play.
- the fastening of these drill bushes 13 is accomplished with screws 15 which are located in the receiving bushing 8.
- a mounting bushing 16 is inserted as an assembly aid during the assembly of these elements. Furthermore, two low-friction ball bearings 10 are each mounted on the receiving bushing 8, which are fastened with snap rings 11. At the head of the low-friction ball bearing 10 there is the foil steering bushing 2, which is clamped in with the two low-friction bearings due to its special geometry.
- a groove 17 is machined into the receiving shaft 4 according to FIG. 6 so that it is located exactly in the middle of the two rotatable bearings 13, 14.
- square rods 18 are inserted to the right and left of the center of the receiving shaft.
- transverse grooves are provided in the center distance of the pivotable segments, in which the spherically shaped heads of the ball pins 19 located in the receiving bushing 8 are embedded without play.
- the ball bolts 19 are held in the receiving bushings 8 without play by means of threaded screws 15.
- the ball pins In order to avoid a higher accuracy of the groove spacing in the square rods 18, the ball pins have a small eccentricity of approximately 1 mm.
- the zero position or 90 degree position of the bushings 8 is also achieved with the aid of a mounting bush 16 guaranteed, the two square rods 18 are fixed in advance in their zero position.
- a stepper motor 7 is provided as a replacement for the manually adjustable micrometer drive 20, which in small steps, the or the square bars 18, preferably with the help of a pinion and a toothing 23, moves and thus accomplishes the angular adjustment.

Description
Die Erfindung betrifft eine Walze zum Führen und Strekken von Bändern und/oder Folienbahnen für Wickeleinrichtungen, vorzugsweise für Vorrichtungen zum kontinuierlichen Bedampfen oder Besputtern von Kunststoff- oder Papierbändern und -bahnen im Vakuum mit einer Vielzahl von auf der Walzenachse hintereinanderliegend angeordneten nach Art von Wälzkörperlagern auf der Walzenachse über Wälzkörper drehbar gehaltene Außenbuchsen gleicher Konfiguration, wobei die Außenbuchsen berührungsfrei und im Abstand zueinander gehalten sind und das Folienband oder die Folienbahn die Außenbuchsen teilweise umschlingt und dabei mit Vorspannung an Partien der Zylindermantelfläche der Außenbuchsen anliegt. Bekannt ist eine Streck- und Stauchwalze für Bogen oder Bahnen aus biegsamen Werkstoff (DE-PS 892 286), die zwischen den Endabschnitten eine gebogene Strecke aufweist und die - mit der gebogenen Achse der Walze in beliebigen Ebenen einstellbar - festgeklemmt werden kann. Derartige Streck- und Stauchwalzen sind mit einem elastischen Schlauch aus textilem Werkstoff versehen, der über die einzelnen Walzenabschnitte gezogen ist und so für einen kontinuierlichen Lauf der Walzenabschnitte sorgt. Diese bekannte Walze hat unter anderem den Nachteil, daß sie sich erfahrungsgemäß stark elektrostatisch auflädt, was bei einer Wickeleinrichtung für eine Sputtervorrichtung nicht akzeptabel ist.The invention relates to a roller for guiding and stretching tapes and / or film webs for winding devices, preferably for devices for the continuous vapor deposition or sputtering of plastic or paper tapes and webs in a vacuum, with a large number of rolling element bearings arranged one behind the other on the roller axis Outer bushes of the same configuration, which are rotatably held on the roller axis via rolling elements, the outer bushes being held in a contact-free manner and at a distance from one another, and the film strip or film web partially wrapping around the outer bushes and thereby being preloaded on parts of the cylindrical surface of the outer bushings. A stretching and upsetting roller for sheets or webs made of flexible material is known (DE-PS 892 286), which has a curved path between the end sections and which can be clamped - adjustable in any plane with the bent axis of the roller. Such Stretching and upsetting rollers are provided with an elastic hose made of textile material, which is pulled over the individual roller sections and thus ensures that the roller sections run continuously. This known roller has the disadvantage, among other things, that experience has shown that it is highly electrostatically charged, which is not acceptable for a sputtering device in a winding device.
Vorgeschlagen wurde auch bereits (P 40 25 232.9) eine Walze zum Führen und Strecken von Bändern und/oder Folienbahnen für Wickeleinrichtungen, vorzugsweise für Vorrichtungen zum kontinuierlichen Bedampfen oder Besputtern von Kunststoffbändern und -bahnen im Vakuum, bei der eine Vielzahl von auf der Walzenachse hintereinanderliegend angeordnete, nach Art von Axial-Zylinderrollenlagern auf der Achse über Wälzkörper drehbar geführte Außenbuchse gleicher Konfiguration vorgesehen sind, wobei die Außenbuchsen berührungsfrei im Abstand zueinander gehalten sind und das Folienband oder die Folienbahn die Außenbuchsen teilweise umschlingt und dabei mit Vorspannung an Partien der Zylindermantelfläche der Außenbuchsen anliegt.Also proposed (P 40 25 232.9) is a roller for guiding and stretching strips and / or film webs for winding devices, preferably for devices for the continuous vapor deposition or sputtering of plastic strips and webs in a vacuum, in which a large number of consecutive ones on the roller axis arranged, in the manner of axial cylindrical roller bearings on the axis via rolling elements rotatably guided outer bushing of the same configuration are provided, the outer bushings are kept in contact-free distance from each other and the film strip or film web partially wraps around the outer bushings and thereby with pre-tension on parts of the cylindrical surface of the outer bushings is present.
Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Walze des in Frage stehenden Typs zu schaffen, die preiswert in der Herstellung ist, deren Gleichlauf von besonderer Präzision ist, die geringe Geräusche erzeugt, die hohe Drehzahlen bei Vermeidung eines besonderen Schmiersystems ermöglicht und die auch unter den Bedingungen eines Hochvakuums ihre Eigenschaften behält, also beispielsweise keine Teile enthält, die aus Werkstoffen bestehen, die zum Ausgasen und damit zum Brüchigwerden neigen. Darüberhinaus soll je nach Folienart und -beschaffenheit entweder die ganze Walze und/oder die mit der Folie unmittelbar zusammenwirkenden Segmente während des Betriebes verstellbar sein, so daß die Folie in jedem Augenblick gerade und glatt ziehbar ist.The present invention has for its object to provide a roller of the type in question, which is inexpensive to manufacture, the synchronization of which is particularly precise, which generates low noise, which enables high speeds while avoiding a special lubrication system, and also maintains its properties under the conditions of a high vacuum, i.e., for example, does not contain any parts that are made of materials that tend to outgas and thus become brittle. In addition, depending on the type and nature of the film, either the entire roller and / or the segments interacting directly with the film can be adjustable during operation, so that the film can be pulled straight and smooth at any moment.
Diese Aufgabe wird gemäß der Erfindung durch mindestens einen in einer Längsnut der Walzenachse längsverschiebbar gehaltenen und geführten Profilstab gelöst, der mit Zapfen oder Kugelbolzen zusammenwirkt, die in den den Außenbuchsen jeweils zugeordneten Aufnahmebuchsen gehalten oder einstückig mit diesen ausgebildet sind und sich radial nach innen zu bis in Ausnehmungen hineinerstrecken, die am Profilstab in Abständen angeordnet sind, wobei eine Längsverschiebung des Profilstabs die kippbar auf der Walzenachse gelagerten Aufnahmebuchsen gegenüber der Längsachse der Walzenachse verschwenkt.This object is achieved according to the invention by at least one longitudinally displaceably held and guided profile rod in a longitudinal groove of the roll axis, which cooperates with pins or ball pins which are held in the receptacle bushes assigned to the outer bushings or are formed integrally therewith and radially inwards up to extend into recesses which are arranged on the profile bar at intervals, a longitudinal displacement of the profile bar pivoting the receptacles which are tiltably mounted on the roller axis relative to the longitudinal axis of the roller axis.
Die also rechts und links der Mitte auf der Walzenachse angeordneten Buchsen sind quer zur Wellenachse schwenkbar gelagert. Diese schwenkbar gelagerten Buchsen sind in ihrer Winkligkeit zur Walzenlängsachse so verstellbar, daß je nach Folienqualität eine Breitstreckung oder Dehnung erzielbar ist.The bushings arranged on the right and left of the center on the roller axis are pivoted transversely to the shaft axis. These pivotable bushings are adjustable in their angularity to the longitudinal axis of the roll so that, depending on the quality of the film, spreading or stretching can be achieved.
Der Spalt zwischen den einzelnen Segmenten oder Buchsen ist zweckmäßigerweise dazu so gewählt, daß er den Breitstreckvorgang nicht beeinflußt wird. Außerdem kann bei dieser geraden Breitstreckwalze, die keine Bogenwölbung besitzt, der Abstand zur nächsten Walze sehr klein sein, was wiederum zu einem geringen Platzbedarf führt.The gap between the individual segments or bushings is expediently chosen so that it does not affect the spreading process. In addition, with this straight spreader roll, which has no arching, the distance to the next roll can be very small, which in turn leads to a small space requirement.
Weitere Einzelheiten und Merkmale sind in den Patentansprüchen näher erläutert und gekennzeichnet.Further details and features are explained and characterized in more detail in the patent claims.

Die gerade, manuell winkelverstellbare metallische Breitstreckwalze ist in drehbare Segmente oder Buchsen 2 aufgeteilt, wobei die mittlere feststehende Buchse 1 immer quer bzw. rechtwinklig zur Bahnmitte steht. Die übrigen schwenkbar gelagerten Buchsen 2 sind rechts oder links von der Bahnmitte so angeordnet, daß sie kontinuierlich in einem bestimmten Winkel jeweils zur Mittelachse oder Bahnlinie stehen.The straight, manually angle-adjustable metallic spreader roller is divided into rotatable segments or
Eine mögliche Variante dieser Anordnung besteht darin, daß man einen Teil der Buchsen 2 jeweils von der Mitte aus mit kleinerem Winkel anstellt und die Randsegmente bzw. die Buchsen 2 an den beiden Enden der Walzenachse 4 in ihrer Winkligkeit stärker verschwenkt.A possible variant of this arrangement consists in that a part of the

Um eine möglichst genaue Winkeleinstellung vornehmen zu können, befindet sich am Ende jedes verschiebbaren Profilstabs 18 je ein Verstelltrieb 20 mit einer drehbaren Spindel und einer Steigung von z. B. 0,5 mm sowie mit einer zusätzlichen Feststellvorrichtung.In order to be able to make the most precise possible angle adjustment, there is an adjusting
Der Verstelltrieb 20 ist einerseits mit der Aufnahmewelle 4 fest verbunden, andererseits an den beiden verschiebbaren Profilstäben angeklemmt. Vor der Montage der Buchsen 2 ist auf die Nullstellung und Feststellung des Verstelltriebs zu achten. Die Winkeleinstellgenauigkeit der Buchsen kann bei dieser Anordnung pro 1/4 Umdrehung des Verstelltriebs ca. 0,2 Grad betragen.The adjusting

Die Lagerung dieser manuell winkelverstellbaren metallischen Breitstreckwalze geschieht über zwei Lagerschilde 3, die die Endzapfen 5 der Aufnahmewelle 4 umschließen und die ihrerseits am Maschinengestell schwenkbar befestigt sind, um eine Änderung des Umschlingungswinkels zu bewerkstelligen.The storage of this manually angle-adjustable metallic spreader roller takes place via two
Um weiter den richtigen Breitstreckpunkt für die Breitstreckwalze zu erreichen, ist entweder ein skaliertes Handrad 6 mit Feststellung oder ein Motor 7 für die Umschlingungsänderung vorgesehen.In order to continue to reach the correct spreading point for the spreading roller, either a scaled handwheel 6 with a lock or a
Die mittlere feststehende Buchse nach Figur 4 besteht aus einer Aufnahmebuchse 8, die fest auf der Aufnahmewelle 4 mittels Sprengringen 9 befestigt ist. Weiter sind auf der Aufnahmebuchse 8 zwei Leichtlaufkugellager 10 angeordnet, die mit Sprengringen 11 befestigt sind. Vor dem Einbau dieser Lager ist darauf zu achten, daß sie vorab vakuumtechnisch abgepumpt werden, um einen Fettaustritt während des Prozesses zu verhindern. Am Kopf der Leichtlaufkugellager 10 befindet sich die Außenbuchse 12, die durch ihre besondere Geometrie von den zwei Leichtlauflagern 10 gehalten ist. Durch diese Geometrie der Buchse 12 bzw. durch die Schultern 25 ist eine Unwucht praktisch ausgeschlossen (rotationssymmetrisches Teil).The middle fixed bushing according to FIG. 4 consists of a receiving
Die übrigen, beiderseits der mittleren feststehenden Buchse 1 angebrachten Buchsen 2 (Figur 5) sind sämtlich schwenkbar auf der Aufnahmewelle 4 gelagert.The remaining bushes 2 (FIG. 5) attached on both sides of the middle fixed bushing 1 are all pivotally mounted on the
Im einzelnen besteht jedes Segment aus einer Aufnahmebuchse 8, die mittels zweier Bohrbuchsen 13 und zwei Kugeln 14 spielfrei in Senkbohrungen 22 der Aufnahmewelle 4 gelagert sind. Die Befestigung dieser Bohrbuchsen 13 wird mit Schrauben 15 bewerkstelligt, die sich in der Aufnahmebuchse 8 befinden.In particular, each segment consists of a receiving
Um stets gleiche Abstände zwischen der Aufnahmebuchse 8 und der Aufnahmewelle 4 zu erreichen, wird bei der Montage dieser Elemente eine Montagebuchse 16 als Montagehilfe zwischengeschoben. Weiter sind auf der Aufnahmebuchse 8 jeweils zwei Leichtlaufkugellager 10 gelagert, die mit Sprengringen 11 befestigt sind. Am Kopf der Leichtlaufkugellager 10 befindet sich die Folienlenkbuchse 2, die durch ihre besondere Geometrie mit den zwei Leichtlauflagern eingeklemmt ist.In order to always achieve the same distances between the receiving
Für die Verstellung der Segmente ist nach Figur 6 eine Nut 17 in die Aufnahmewelle 4 so eingearbeitet, daß diese sich genau in der Mitte der beiden drehbaren Lager 13, 14 befindet. In diese Nut 17 sind rechts und links von der Mitte der Aufnahmewelle 4 Vierkantstäbe 18 verschiebbar eingelegt. In den Vierkantstäben 18 sind im Mittelabstand der schwenkbaren Segmente Quernute angebracht, in denen die kugelig ausgeformten Köpfe der in der Aufnahmebuchse 8 befindlichen Kugelbolzen 19 spielfrei eingelagert sind.For the adjustment of the segments, a
Die Kugelbolzen 19 sind in den Aufnahmebuchsen 8 spielfrei mit Hilfe von Gewindeschrauben 15 gehalten. Um sich eine höhere Genauigkeit der Nutabstände in den Vierkantstangen 18 zu ersparen, haben die Kugelbolzen eine kleine Exzentrizität von ca. 1 mm. Bei der Montage dieser Kugelbolzen wird auch mit Hilfe einer Montagebuchse 16 die Nullstellung bzw. 90 Grad Stellung der Buchsen 8 gewährleistet, wobei die beiden Vierkantstäbe 18 schon vorab fest in ihrer Nullstellung fixiert sind.The
Bei der motorisch winkelverstellbaren metallischen Breitstreckwalze nach Figur 3 besteht der einzige Unterschied zur Ausführung nach Figur 1 darin, daß als Ersatz für den handverstellbaren Mikrometertrieb 20 ein Schrittmotor 7 vorgesehen ist, der in kleinen Schritten den oder die Vierkantstäbe 18, vorzugsweise mit Hilfe eines Ritzels und einer Verzahnung 23, bewegt und damit die Winkelverstellung bewerkstelligt.3, the only difference from the embodiment according to FIG. 1 is that a
