Abstract

A sectional ring (2), especially suited as a rotary tensioning roller, has at least one intentional reflex bend (4, 14). Two such bends may be included; hence seen in cross section, the roller section is approximately Z-shaped. The bridging section has a pair of parallel edges enclosing an angle with the axis, or it may become thicker towards the axis. As construction materials, rubber, natural rubber, plastic or similar are suitable. The key feature is that when radial pressure is exerted onto the ring, the outer cylindrical surface (20) shifts its position along the axis, but maintains parallelism with that axis. In addition to the sectional ring, a stretching-roller formed with its aid, and the procedure to manufacture a complete, smooth-surfaced roller are also claimed.

Description

Die Erfindung betrifft einen Lamellenring sowie eine aus einzelnen Lamellenringen zusammengesetzte Einrichtung zur Führung bahnförmiger Materialien, beispielsweise Papier-, Textil- oder Folienbahnen und ein Verfahren zu deren Herstellung.The invention relates to a lamellar ring and a device composed of individual lamellar rings for guiding web-shaped materials, for example paper, textile or film webs, and a method for their production.

Derartige Einrichtungen, auch Breitstreckwalzen genannt, gibt es in unterschiedlichen Ausführungen. Bekannt sind die sogenannten "Bananenwalzen", die bananenartig gewölbt ausgebildet sind, wobei die Walzen in einzelne verformbare Abschnitte unterteilt sind, damit sich die Walze, wenn ein bahnförmiger Stoff über sie geführt wird, unter Ausbildung eines im wesentlichen zylinderabschnittförmigen Oberflächenabschnittes verformen kann. Diese Art der Walzen ist aber sehr wartungsintensiv. Weitere Formen sind Walzen mit einem verformbaren Breitstreckbelag, der üblicherweise mit schräg zur Achse angeordneten Nuten versehen ist, so daß der Belag in einzelne Segmente unterteilt ist, welche bei Druckbeaufschlagung links und rechts zu den Walzenenden hin kippen. Durch das Kippen der Segmente werden ihre Oberflächen ,die im unbelasteten Zustand parallel zur Walzenachse stehen, geneigt, wodurch die Parallelität verloren geht und die Walze eine gewellte Oberfläche bekommt. Durch die Haftkräfte wird auch eine über eine derartige Walze laufende Bahn zu den beiden Enden hin gestreckt. Nachteilig ist hier jedoch die ungleichmäßige Oberfläche, da insbesondere bei sehr dünnen oder empfindlichen Bahnen z.B. Folien oder Seide, durch die Nuten bedingte Abdrücke oder Falten entstehen können, wodurch das Endprodukt praktisch wertlos und somit Ausschuß wird. Auch im Farbbereich von Textilmaschinen haben diese Walzen Nachteile, da die Farbe in die Nuten eindringt und bei einem Farbwechsel die Textilien mit der zuvor verwendeten Farbe streifenförmig zeichnen würde. Es ist bekannt, daß Walzen solcher Art bei mechanischer Beschädigung einzelner Segmente komplett abgedreht und neu aufgebaut werden müssen, was für den Endverbraucher sehr aufwendig und kostenintensiv ist.Such devices, also called spreader rolls, are available in different versions. Known are the so-called "banana rollers", which are configured like a banana, the rollers being subdivided into individual deformable sections, so that the roller, when a web-shaped material is passed over it, can deform to form an essentially cylindrical section-shaped surface section. However, this type of roller is very maintenance-intensive. Other shapes are rollers with a deformable spreader covering, which is usually provided with grooves arranged obliquely to the axis, so that the covering is divided into individual segments which tilt to the left and right towards the roller ends when pressure is applied. By tilting the segments, their surfaces, which are parallel to the roller axis in the unloaded state, are inclined, whereby the parallelism is lost and the roller gets a corrugated surface. A web running over such a roller is also stretched towards the two ends by the adhesive forces. However, the uneven surface is disadvantageous here, since in particular with very thin or sensitive webs, e.g. Foils or silk, through which grooves can cause marks or wrinkles, making the end product practically worthless and therefore rejects. These rollers also have disadvantages in the color range of textile machines, since the color penetrates into the grooves and if the color were changed, the textiles would draw strips with the previously used color. It is known that rollers of this type have to be completely turned off and rebuilt in the event of mechanical damage to individual segments, which is very time-consuming and costly for the end user.

Die DE- A- 30 16 321 zeigt unter anderem eine Walze, die aus einzelnen Ringscheiben besteht, die untereinander mit Stäben verbunden sind und mit einer Druckrolle seitlich verschoben werden können. Diese Ausführung ist jedoch nur als Bandlaufregulierung einsetzbar und benötigt für diese Funktion eine elektrische oder pneumatische Steuereinheit.DE-A-30 16 321 shows, among other things, a roller which consists of individual ring disks which are connected to one another with rods and can be moved laterally with a pressure roller. However, this version can only be used as a belt run control and requires an electrical or pneumatic control unit for this function.

Die EP-A- 0 381 244 beschreibt eine Breitstreckwalze, wobei auf den tragenden Kern ein Streifen in Form einer Schraubenlinie als Belag aufgewickelt ist, auf dessen Umfang eine zu fördernde und in ihrer Breite zu streckende Bahn aufliegt. Durch die schraubenförmige Oberfläche ist nur eine ungenügende Breitstreckwirkung erzielbar und die vorhandenen Nuten würden unerwünschte Spuren auf der Oberfläche einer darüber laufenden Materialbahn hinterlassen.EP-A-0 381 244 describes a spreader roll, a strip in the form of a helical line being wound onto the supporting core, on the base of which Circumference of a web to be conveyed and stretched in its width. Due to the helical surface, an insufficient spreading effect can be achieved and the existing grooves would leave undesired traces on the surface of a material web running over it.

Die EP-A- 0 026 467 beschreibt eine Breitstreckwalze, bei der auf einer nicht drehenden Welle ein Stahlschlauch drehbar abgestützt und zentriert ist. Die Konstruktion ist äußerst kompliziert in Fertigung und Wartung und kostenintensiv.EP-A-0 026 467 describes an spreader roll in which a steel hose is rotatably supported and centered on a non-rotating shaft. The design is extremely complicated to manufacture and maintain and is costly.

Der Erfindung liegt die Aufgabe zugrunde, obige Nachteile zu vermeiden und eine zylindrische Walze mit glatter Oberfläche ohne verschleißanfällige Mechanik zu schaffen, die die erforderliche Breitstreckwirkung erzielt.The invention has for its object to avoid the above disadvantages and to provide a cylindrical roller with a smooth surface without wear-prone mechanics, which achieves the required spreading effect.

Die Erfindung beruht auf einer speziellen Form von Lamellenringen, die im Querschnitt Z-förmig ausgebildet sind und im wesentlichen zwei Sollknickstellen aufweisen, wodurch eine definierte Verformung der Oberfläche erzielt werden kann, sowie gegebenenfalls einem speziell für diese Lamellenringe ausgeführten Schlauch mit innenliegender Profilierung.The invention is based on a special shape of lamellar rings, which are Z-shaped in cross-section and essentially have two predetermined kink points, as a result of which a defined deformation of the surface can be achieved, and, if appropriate, a hose with an internal profiling specially designed for these lamellar rings.

Die erforderliche Breitstreckwirkung wird dadurch erreicht, daß auf einem Walzenkem der Erfindung zugrundeliegende Lamellenringe von der Mittelebene ausgehend links und rechts symmetrisch angebracht werden, wobei die Ringe aneinandergereiht, eine nahezu geschlossene Oberfläche bilden, wobei sich bei einer radialen Druckbeaufschlagung, z.B. durch die Spannung der darüber laufenden Materialbahn, der äußere Umfang axial und symmetrisch zur axialen Mittelebene verschiebt und die zylindrische Oberfläche die Parallelität zur Walzenachse beibehält. In einer bevorzugten Ausführungsform der Erfindung weist der Belag der einzelnen Lamellenringe unterschiedliche Shore-Härten auf, wobei von der Mitte ausgehend zu den Walzenenden hin die Shore-Härte abnehmen kann. So kann die Breitstreckwirkung positiv beeinflußt werden.The required spreading effect is achieved in that, on a roll core of the invention, lamellar rings on the basis of the center plane are attached symmetrically left and right, the rings being lined up, forming an almost closed surface, with radial pressure being applied, e.g. due to the tension of the material web running over it, the outer circumference shifts axially and symmetrically to the axial central plane and the cylindrical surface maintains the parallelism to the roller axis. In a preferred embodiment of the invention, the covering of the individual lamellar rings has different Shore hardnesses, the Shore hardness decreasing from the center toward the roller ends. The spreading effect can be positively influenced.

Über diese aus einzelnen Ringen gefertigte Breitstreckwalze kann nun ein flexibler Belag, beispielsweise in schlauchförmiger Ausführung mit glatter Oberfläche und innenliegenden Radialvorsprüngen, die in die dafür vorgesehenen Zwischenräume der aneinander gereihten Ringe einrasten, aufgezogen werden. Dies ist besonders vorteilhaft für einen Betrieb im Naßbereich.A flexible covering, for example in a tubular design with a smooth surface and internal radial projections, which snap into the spaces provided for this purpose of the rings lined up, can now be fitted over this spreader roller made from individual rings. This is particularly advantageous for operation in the wet area.

Durch die glatte Oberfläche wird eine Beschädigung oder Zeichnung von feinsten, darüber laufenden Materialien vermieden. Außerdem läßt sich die Oberfläche auch von Verunreinigungen wie z.B. Farbresten leicht reinigen. Dies ist besonders im Färbebereich von Textil- und Papierindustrie von Vorteil. Die Walze kann aber auch vorteilhaft in der Folienindustrie zur Erzeugung von Magnetbändern (Bild- und Tonträger) sowie für die Erzeugung von feinster Aluminiumfolie eingesetzt werden.The smooth surface prevents damage or drawing of the finest materials running over it. In addition, the surface can also be easily cleaned of contaminants such as paint residues. This is particularly advantageous in the dyeing area of the textile and paper industry. However, the roller can also be used advantageously in the film industry for the production of magnetic tapes (image and sound carriers) and for the production of the finest aluminum foil.

Speziell bei der Aluminiumfolie würde eine herkömmliche, mit Nuten versehene Breitstreckwalze unweigerlich ihre Spuren hinterlassen.In the case of aluminum foil in particular, a conventional grooved spreader roller would inevitably leave its mark.

Zur Erzielung der Breitstreckwirkung sind die Vorsprünge vorteilhaft zur axialen Mittelebene der Walze symmetrisch, wobei sich in der Mittelebene ein in sich symmetrischer Vorsprung befindet. Der Vorsprung der Mittelebene, der vorzugsweise rechteckig ist, bleibt während des Breitstreckvorganges an seiner Stelle fixiert, während sich die übrigen Vorsprünge zu den Enden der Walze verschieben.In order to achieve the spreading effect, the projections are advantageously symmetrical with respect to the axial central plane of the roller, with an intrinsically symmetrical projection being located in the central plane. The projection of the central plane, which is preferably rectangular, remains fixed in place during the spreading process, while the remaining projections shift towards the ends of the roller.

Eine weitere Ausbildung der Erfindung ist das Doppelsystem, das überall dort Anwendung findet, wo über den Umschlingungswinkel und die Zugkraft der Warenbahn kein genügend großer Flächendruck erzeugt werden kann, um die Lamellenringe zu deformieren. Dabei werden zwei erfindungsgemäße Walzen über- oder nebeneinander angeordnet, wobei eine davon parallel zur anderen verstellbar ist. Durch das Aneinanderdrücken der beiden Walzen werden die Lamellenringe an den Berührungslinien der Walzen deformiert, wobei an dieser Stelle die Oberfläche der Walzen axial von der Mitte ausgehend zu den Walzenenden hin gestreckt werden kann. Eine durch dieses Doppelsystem geführte Warenbahn wird somit kontinuierlich über die Breite gestreckt.Another embodiment of the invention is the double system, which is used wherever the wrap angle and the tensile force of the web cannot be used to generate a sufficiently large surface pressure to deform the lamellar rings. Two rollers according to the invention are arranged one above the other or next to one another, one of which is adjustable parallel to the other. By pressing the two rollers together, the lamellar rings are deformed at the contact lines of the rollers, at which point the surface of the rollers can be stretched axially from the center towards the roller ends. A web of goods guided through this double system is thus continuously stretched across the width.

Die Erfindung betrifft auch ein Verfahren zur Herstellung einer Breitstreckwalze nach der Erfindung. Dabei wird der flexible, auf einem Dorn gefertigte Schlauch in ein druckfestes Rohr eingeführt und die Enden des Schlauches nach außen über die Enden des Rohres gestülpt und befestigt. An einem am Rohr angebrachten Saugstutzen wird nun Vakuums angeschlossen und die Luft zwischen Schlauch und Rohrwand entzogen, wobei sich der Schlauch im Durchmesser dehnt und an die Rohrinnenseite angepreßt wird. In diesen, im Durchmesser erweiterten Schlauch wird nun eine mit Lamellenringen versehene Walze eingeführt und positioniert. Nach Abschalten des Vakuums zieht sich der Schlauch wieder zu seinem ursprünglichen Durchmesser zusammen, wobei die Innenprofilierung in die dafür vorgesehenen Zwischenräume am Umfang der Lamellenringe einrastet. Durch dieses Verfahren wird eine Beschädigung der Lamellenringe oder des Schlauches ausgeschlossen. Nachdem die Walze dem Rohr entnommen wurde, werden die überstehenden Schlauchenden an den Stirnseiten der Walze auf Maß geschnitten.The invention also relates to a method for producing an spreader roller according to the invention. The flexible hose, which is manufactured on a mandrel, is inserted into a pressure-resistant tube and the ends of the tube are slipped over the ends of the tube and fastened. Vacuum is now connected to a suction nozzle attached to the pipe and the air between the hose and the pipe wall is extracted, the hose expanding in diameter and being pressed against the inside of the pipe. A roller with lamellar rings is now inserted and positioned in this tube, which has an enlarged diameter. After switching off the vacuum, the hose contracts again to its original diameter, the inner profile snapping into the spaces provided on the circumference of the lamella rings. This method prevents damage to the lamellar rings or the hose. After the roller has been removed from the tube, the protruding hose ends are cut to size on the end faces of the roller.

Darauf befinden sich die Lamellenringe (2), die von der Mitte ausgehend nach links und rechts verlaufend, gegensinnig aneinandergereiht angeordnet sind. Am äußeren Umfang sind die Lamellenringe (2) so ausgebildet, daß sich an den Berührungsflächen zwischen den einzelnen Ringen ein in der Grundform dreieckiger Zwischenraum (9) entsteht (siehe Detail Z). Diese Zwischenräume (9) verlaufen radial zur Achse der Lamellenringe (2). Über den Lamellenringen (2) ist der flexible Schlauch (3) mit innenliegender Profilierung aufgezogen. Die innenliegenden Vorsprünge (10) rasten dabei in die Zwischenräume (9) ein. Der Vorsprung (11) liegt in der Mittelebene der Walze und fixiert den Schlauch (3) in seiner Position.

It consists of a roller core (1), which is usually made of metal, in particular steel. On it are the lamellar rings (2), which run from the center to the left and right, lined up in opposite directions. On the outer circumference, the lamellar rings (2) are designed in such a way that a space (9) with a triangular shape is created on the contact surfaces between the individual rings (see detail Z). These spaces (9) run radially to the axis of the lamellar rings (2). The flexible hose (3) with internal profiling is fitted over the lamellar rings (2). The internal projections (10) snap into the spaces (9). The projection (11) lies in the central plane of the roller and fixes the hose (3) in its position. Section A-A shows the structure of the roller in cross section.

Diese von der Mitte ausgehende und nach rechts und links in Richtung der Pfeile (12) verlaufende Auslenkung der Lamellenringe (2) wird auf dem mit innenliegender Profilgebung ausgeführten Schlauch (3) übertragen. Über den Kraftschluß der Warenbahn (5) und der Oberfläche des Schlauches (3) wird die Warenbahn in axialer Richtung gestreckt. So werden vorhandene Falten entfernt bzw. eine Faltenbildung vermieden. Durch die Drehbewegung (13) der Walze (1) richten sich die Lamellen der Lamellenringe (2) nach Verlassen der Berührungsfläche (7) wieder auf und die Walzenoberfläche schrumpft in diesem Bereich wieder auf ihre Fertigungslänge. Dieser Vorgang wiederholt sich kontinuierlich, solange die Walze durch die Warenbahn angetrieben wird. Um die Lamellenringe (2) auf dem Walzenkern (1) zu fixieren werden an den Walzenenden entsprechende Ringe aufgeschrumpft bzw. aufgeklebt. Dadurch kann als Grundkörper ein Walzenkern mit glatter Oberfläche verwendet werden.The spreading function of the roller is shown in Fig. 2. The material web (5) acts by means of wrapping and tension, a surface pressure (4) on the surface of the roller formed by the flexible covering (3), whereby the lamellar rings (2), in opposite directions from the center plane, bend axially outwards. This deflection of the lamellar rings (2), which starts from the center and runs to the right and left in the direction of the arrows (12), is transmitted to the hose (3) with an internal profile. The web is stretched in the axial direction over the frictional connection of the web (5) and the surface of the hose (3). In this way, existing wrinkles are removed or wrinkles are avoided. As a result of the rotary movement (13) of the roller (1), the lamellae of the lamella rings (2) straighten up again after leaving the contact surface (7) and the roller surface shrinks back to its production length in this area. This process is repeated continuously as long as the roller is driven by the web. In order to fix the lamellar rings (2) on the roller core (1), appropriate rings are shrunk or glued onto the roller ends. As a result, a roller core with a smooth surface can be used as the base body.

Fig. 3 und 4 stellen die schematische Darstellung des Doppelsystems und dessen Funktion dar. Es werden hierfür zwei Walzen des oben beschriebenen Systems je nach Bahnführung übereinander oder nebeneinander angeordnet, wobei eine der beiden Walzen mechanisch abgehoben bzw. angepreßt werden kann. Durch den beim Zusammenfahren entstehenden Liniendruck werden die unter dem profilierten Schlauch (3) liegenden Lamellenringe (2) axial von der Mitte ausgehend links und rechts verlaufend nach außen, d.h. zu den Walzenenden hin, gelenkt, wobei sich der Schlauch (3) der beiden Walzen (1) axial dehnt und die dazwischenliegende Warenbahn (5) in der Breite gestreckt wird. Durch Veränderung des Liniendruckes (8) kann die Breitstreckwirkung erhöht oder gemindert werden.3 and 4 represent the schematic representation of the double system and its function. For this purpose, two rollers of the system described above are arranged one above the other or next to one another, depending on the web guide, one of the two rollers being able to be lifted off or pressed on mechanically. Due to the line pressure created when moving together, the lamellar rings (2) located under the profiled hose (3) are axially extending from the center to the left and right, i.e. steered towards the roller ends, the hose (3) of the two rollers (1) expanding axially and the intermediate fabric web (5) being stretched in width. The spreading effect can be increased or decreased by changing the line pressure (8).

Unter Fig. 5 wird ein einzelner Lamellenring (2) im Schnitt in drucklosem und druckbeaufschlagtem Zustand dargestellt. Um die Parallelität zur Mittelachse der Druckbeaufschlagung beizubehalten, ist der Lamellenring (2) mit zwei Sollknickstellen (4) und (14) versehen.A single lamellar ring (2) is shown in section in FIG. 5 in a depressurized and pressurized state. In order to maintain the parallelism to the central axis of the pressurization, the lamellar ring (2) is provided with two predetermined bending points (4) and (14).

Bei der Druckbeaufschlagung wird der äußere zylindrische Umfang (20) des Lamellenringes (2) um die Strecke dx nach unten gedrückt, wobei gleichzeitig eine axiale Verschiebung dli ausgeführt wird.When pressure is applied, the outer cylindrical circumference (20) of the lamellar ring (2) is pressed down by the distance dx, an axial displacement dli being carried out at the same time.

Fig. 5 a und 5 b zeigen die Vorrichtung zur Herstellung einer Walze nach der Erfindung. Die Vorrichtung besteht dabei aus einem Rohr (15) mit einem Luftanschluß (16). Der flexible Belag (3) wird in das Rohr eingeführt, an dessen Enden umgestülpt und z. B. mit Schlauchschellen (18) am Rohr (15) fixiert. Durch anlegen eines Vakuums am Luftanschluß (16) in Richtung (17) wird der Belag (3) an der Innenseite des Rohres angesaugt und auseinander gedehnt. Anschließend wird eine konventionelle Breitstreckwalze (1) in Achsrichtung in das Rohr eingeführt und positioniert. In weiterer Folge kann in Richtung (19) ein Druckausgleich durchgeführt werden, worauf sich der flexible Belag (3) um die Walze (1) fest anlegt. Nach Lösen der Befestigungen (18) wird die fertige Einrichtung dem Rohr (15) entnommen und der überstehende Belag (3) abgetrennt. Grundsätzlich kann auch der flexible Belag durch Druckluft in seinem Inneren an das Rohr gepreßt werden und nach Einführen der Walze (1) wieder Normaldruck hergestellt werden, wodurch sich der Belag ebenfalls an die Walze preßt.5 a and 5 b show the device for producing a roller according to the invention. The device consists of a tube (15) with an air connection (16). The flexible covering (3) is inserted into the tube, turned upside down at the ends and z. B. with hose clamps (18) on the tube (15). By applying a vacuum to the air connection (16) in direction (17), the covering (3) on the inside of the tube is sucked in and expanded. A conventional spreader roller (1) is then inserted into the tube and positioned in the axial direction. Subsequently, a pressure equalization can be carried out in direction (19), whereupon the flexible covering (3) lies firmly around the roller (1). After loosening the fastenings (18), the finished device is removed from the pipe (15) and the protruding covering (3) is separated. In principle, the flexible lining can also be pressed against the tube by compressed air and normal pressure can be restored after the roller (1) has been inserted, as a result of which the lining also presses against the roller.

Fig. 6 zeigt eine Walzenausführung ohne darüber gezogenen Schlauch, wobei die einzelnen Lamellenringe parallele Kanten der Stege aufweisen. In der Mitte der Walze befinden sich hier zwei speziell gestaltete Lamellenringe mit zur Walzenmitte hin verlängerter Oberfläche. Ein einzelner derartiger Ring ist in Fig. 7 a dargestellt. Fig. 7 b zeigt einen Schnitt durch einen Lamellenring mit sich zur Achse hin erweiterndem Steg.6 shows a roller design without a hose pulled over it, the individual lamella rings having parallel edges of the webs. In the middle of the roller there are two specially designed lamella rings with a surface extended towards the middle of the roller. A single such ring is shown in Fig. 7 a. 7 b shows a section through a lamellar ring with a web that widens towards the axis.

Die Erfindung ist nicht durch die dargestellten Beispiele beschränkt, es können vielmehr auch andere Formen von Lamellenringen zum Einsatz kommen, wobei jedoch die Parallelität der Oberfläche bei Druckbeanspruchung erhalten bleibt.The invention is not limited by the examples shown, but rather other forms of lamellar rings can be used, but the parallelism of the surface is retained under pressure.
