Description

Die Erfindung bezieht sich auf eine Vorrichtung zum kon­taktlosen Biegen eines durchlaufenden Bandmaterials, ins­besondere einer Textilbahn.The invention relates to a device for contactless bending of a continuous strip material, in particular a textile web.

Zum Führen und Biegen eines Bandmaterials werden bisher kontinuierlich bewässerte Drehwalzen oder Tragbänder ver­wendet, deren Umfangsgeschwindigkeit mit der Bandgeschwin­digkeit synchron ist. Ein solches Tragband muß in kleinen Zeitabständen abgewaschen und getrocknet werden. Das be­druckte Band berührt das Tragband, bzw. die bewässerte Drehwalze immer mit seiner Unterseite, da jegliche Berüh­rung der Oberseite zum Verwischen der aufgetragenen Farbe führen kann. Dadurch ist ein Biegen des Bandes von der Oberseite her ausgeschlossen.Up to now, continuously irrigated rotating rollers or carrier belts have been used to guide and bend a strip material, the peripheral speed of which is synchronized with the strip speed. Such a carrier tape must be washed and dried at short intervals. The printed tape always touches the carrier tape or the irrigated rotating roller with its underside, since any contact with the top can lead to the smeared paint. This prevents the belt from bending from the top.

Eine moderne aus einer Flachdruckmaschine und einem Trockenabteil bestehende Druckstraße ist häufig mehrere zehn Meter lang, wobei von der Gesamtlänge der Anlage un­gefähr je eine Hälfte auf die Flachdruckmaschine und auf das Trockenabteil entfällt. Druckstraßen mit diesen Län­genabmessungen können in bestehenden Fertigungshallen nur mit erheblichen Schwierigkeiten und Umbauten untergebracht werden. Eine Verringerung der Länge bekannter Druckstraßen ist bisher nicht möglich.A modern printing line consisting of a planographic printing press and a drying compartment is often several ten meters long, of which about one half of the total length of the system is for the planographic printing machine and one for the drying compartment. Printing lines with these length dimensions can only be accommodated in existing production halls with considerable difficulties and conversions. A reduction in the length of known printing lines has not yet been possible.

Ein kontaktloses Biegen eines dichten Bandmaterials kann z.B. durch die Verwendung eines bekannten Hohlzylinders mit Perforation im erforderlichen Bogenabschnitt und durch aus den Perforationsöffnungen ausströmende Druckluft erzielt werden. Zwischen dem Band und dem Zylinder wird ein Überdruckspalt gebildet, der eine Berührung verhin­dert. Für dichte Bänder und Folien von größerer Dicke und Steifigkeit kann dieses Verfahren zufriedenstellend arbei­ten. Die Steifigkeit und Dichte eines Textilbandes ist je­doch so gering, daß dieses Verfahren eine örtliche Berüh­rung nicht vermeiden kann.Non-contact bending of a dense strip material can e.g. can be achieved by using a known hollow cylinder with perforation in the required arc section and by compressed air flowing out of the perforation openings. An overpressure gap is formed between the belt and the cylinder, which prevents contact. This method can work satisfactorily for thick tapes and foils of greater thickness and rigidity. However, the stiffness and density of a textile tape is so low that this process cannot avoid local contact.

Aus der DE 29 22 985 C2 ist eine Biegevorrichtung für Bandmaterial bekannt, auf der das Band von der - un­bedruckten - Unterseite her gebogen wird. Der dort ange­gebene Abstand von ca. 3 mm zwischen dem Band und dem Bie­gekörper kann allerdings einen berührungslosen Betrieb beim Biegen von der Oberseite her nicht gewährleisten.From DE 29 22 985 C2 a bending device for strip material is known, on which the strip is bent from the - unprinted - underside. The distance of approx. 3 mm specified there between the belt and the bending body cannot guarantee contactless operation when bending from the top.

Aufgabe der Erfindung ist es, die Nachteile bekannter Vor­richtungen zum kontaktlosen Biegen eines durchlaufenden Bandmaterials, insbesondere eines Textilbandes zu besei­tigen, um u.a. die Länge von Flachdruckstraßen wesentlich verringern zu können.The object of the invention is to eliminate the disadvantages of known devices for contactless bending of a continuous strip material, in particular a textile strip, in order, inter alia, to to be able to significantly reduce the length of planographic printing lines.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß wenigstens am An- und Ablaufteil einer gekrümmten Fläche entlang ihrer Breite Reihen von Druckluftöffnungen vorge­sehen sind, deren Ausmündungen in Richtung zum durchlau­fenden Bandmaterial orientiert sind.This object is achieved in that rows of compressed air openings are provided at least on the inlet and outlet part of a curved surface along their width, the openings of which are oriented in the direction of the continuous strip material.

Die Vorteile der Erfindung bestehen vor allem darin, daß auch leichte und poröse Bänder aus Textilmaterialien am Auslauf des Druckaggregats ohne unerwünschte Kontakte mit der gekrümmten Fläche von der Oberseite her gebogen werden können. Bei Flachdruckmaschinen mit einem aus der CS-A-240 160 bekannten Trockenteil kann dieses über dem Druckaggregat angeordnet werden, was die Gesamtlänge der gesamten Druckstraße wesentlich verkürzt. Die erfin­dungsgemäße Vorrichtung ist konstruktiv einfach und ihre Funktion kann auf einfache Weise durch Dosierung der Druckluftmenge sowie ggfs. Verstellen der Ausströmöff­nungen gesteuert werden.The advantages of the invention consist primarily in the fact that even light and porous tapes made of textile materials can be bent from the top without undesirable contacts with the curved surface at the outlet of the printing unit. In planographic printing machines with a drying part known from CS-A-240 160, this can be arranged above the printing unit, which significantly shortens the overall length of the entire printing line. The device according to the invention is structurally simple and its function can be controlled in a simple manner by metering the amount of compressed air and, if necessary, adjusting the outflow openings.

Weitere Vorteile und Merkmale der Erfindung sind bei den im folgenden anhand der Zeichnung beschriebenen Ausfüh­rungsbeispielen verwirklicht. Es zeigen:

  • Fig. 1: eine bekannte Flachdruckstraße für Textilbänder,
  • Fig. 2: eine schematische Flachdruckstraße mit der er­findungsgemäßen Biegevorrichtung
    und
  • Fig. 3, 4 schematisch zwei Biegevorrichtungen im Quer­schnitt.
Further advantages and features of the invention are realized in the exemplary embodiments described below with reference to the drawing. Show it:
  • 1: a known flat printing line for textile tapes,
  • 2: a schematic planographic printing line with the bending device according to the invention
    and
  • 3, 4 schematically two bending devices in cross section.

Die in Fig. 1 dargestellte Flachdruckstraße für Textilbah­nen enthält eine Flachdruckmaschine a, der eine Trocken­kammer b in gleicher Ebene nachgeordnet ist.The planographic printing line for textile webs shown in Fig. 1 contains a planographic printing machine a, which is followed by a drying chamber b in the same plane.

Bei der in Fig. 2 dargestellten Textildruckstraße ist eine mit einem tragenden Düsensystem ausgerüstete Trockenkammer b über der Flachdruckmaschine a angeordnet, was durch eine Biegevorrichtung c für das durchlaufende Band ermöglicht wird.In the textile printing line shown in FIG. 2, a drying chamber b equipped with a supporting nozzle system is arranged above the planographic printing machine a, which is made possible by a bending device c for the continuous belt.

Die Wand 2 hat bei den Ausführungen nach den Figuren 3 und 4 die Form eines Kreisbogens mit dem Radius R und einer Bogenlänge von mehr als 180°. Sie bildet mit hier recht­winklig verlaufenden Seitenwänden 1′, 1˝ den Hohlkörper 1, der an der Einlaufseite der Trockenkammer b montiert ist. Die Bogenwand 2 kann auch eine anders gekrümmte Form, z.B, mit je einem etwa vertikalen und horizontalen Endteil haben, wobei die dargestellten Formen jedoch aus strö­mungstechnischen und konstruktiven Gründen bevorzugt wer­den. Die beiden Endabschnitte 8, 8′ der Bogenwand 2 begrenzen zusammen mit abgewinkelten Endabschnitten 8, 8′ der Seitenwände 1′, 1˝ zwei sich über die Gesamtlänge er­streckende Reihen von Ausströmkanälen 4, 4′, deren Längs­achsen 7, 7′ etwa zueinander parallel und tangential zu den Endabschnitten 8, 8′ verlaufen. Die Öffnungen 9 der unteren Ausströmkanäle 4 sind schräg in Laufrichtung auf das durchlaufende Band 5 orientiert. Die Öffnungen 9′ der oberen Ausströmkanäle 4′ sind schräg entgegen der Laufrichtung des Textilbands 5 ausgerichtet. In den Hohl­körper 1 wird Druckluft über nicht dargestellte Anschlüsse eingeführt.In the embodiments according to FIGS. 3 and 4, the wall 2 has the shape of a circular arc with the radius R and an arc length of more than 180 °. It forms with here right-angled side walls 1 ', 1˝ the hollow body 1, which is mounted on the inlet side of the drying chamber b. The arch wall 2 can also have a differently curved shape, for example with an approximately vertical and horizontal end part, but the shapes shown are preferred for fluidic and structural reasons. The two end sections 8, 8 'of the arch wall 2 limit together with angled end sections 8, 8' of the side walls 1 ', 1˝ two rows of outflow channels 4, 4' extending over the entire length, the longitudinal axes 7, 7 'of which are approximately parallel to one another and extend tangentially to the end sections 8, 8 '. The openings 9 of the lower outflow channels 4 are oriented obliquely in the running direction on the continuous belt 5. The openings 9 'of the upper outflow channels 4' are aligned obliquely against the running direction of the textile belt 5. Compressed air is introduced into the hollow body 1 via connections not shown.

Bei der Ausführung nach Fig. 4 ist eine weitere Reihe von Ausströmöffnungen 6 im mittleren Bogenbereich vorgesehen. Bei Bedarf können die weiteren Öffnungen in einer jeweils geeigneten versetzten Verteilung in der Bogenwand 2 ange­ordnet sein.4, a further row of outflow openings 6 is provided in the central arc region. If necessary, the further openings can be arranged in a suitable offset distribution in the arch wall 2.

Die erfindungsgemäße Vorrichtung arbeitet so, daß Druck­luft 7 aus den reihenförmigen Öffnungen 9, 9′ in den durch die Pfeiler 7 und 7′ angedeuteten Richtungen ausströmt und im Einklang mit den Gesetzen der Wandströmung der Krümmung der Bogenwand 2 folgt. In dem Raum 3 zwischen der Bogen­wand 2 und dem zu biegenden Bandabschnitt 5, entwickelt sich ein größerer Luftdruck als im Bereich der Ausström­öffnungen 9, 9′. Dies gilt insbesondere für den aus den unteren Ausströmkanälen 4 schräg in Bandlaufrichtung aus­tretenden Luftstrom, der in den sich keilförmig verjüngen­den Bereich zwischen der Bogenwand 2 und dem vertikalen Abschnitt 5˝ des Bands 5 gerichtet ist. Auf diese Weise wird im Raum 3 ein zusammenhängedes Luftpolster erzeugt, das im Unterschied zu einem perforierten Zylinder durch eine lokale Änderung der Spannung im Band 5 nicht beein­trächtigt oder zerstört werden kann. Aus dem Raum 3 ent­weicht die Luft praktisch nur in Richtung der Breite des Bandmaterials 5. Durch Reibung der abströmenden Luft an der Bandoberfläche werden Flattern und Faltenbildungen vermieden. In einigen Fällen ist es zweckmäßig, in der Bogenwand 2 die reihenförmig angeordneten Öffnungen 6 vorzusehen, aus denen die Druckluft 7 in dem mittleren Krümmungsbereich des gebogenen Bandabschnitts 5′ ein­strömt. Die aus den oberen Kanälen 4′ entgegen der Laufrichtung des Bands 5 ausströmenden Luftströme haben vorzugsweise eine Hebefunktion für den horizontalen Anfangsabschnitt 5‴ des gebogenen Bands 5 und erzeugen in dem sich erweiternden Bereich an der Unterseite des Band­abschnitts 5‴ ein zusätzliches Druckpolster, das einen Kontakt des Bandabschnitts 5‴ mit dem oberen Ende der Bogenwand 2 verhindert und der durch das beschleunigte Abströmen der Luft aus dem mittleren Druckpolster in der dem Bandbereich 5′ verursachten Druckabnahme entgegen­wirkt.The device according to the invention works so that compressed air 7 flows out of the row-shaped openings 9, 9 'in the directions indicated by the pillars 7 and 7' and follows the curvature of the arch wall 2 in accordance with the laws of the wall flow. In the space 3 between the arch wall 2 and the band section 5 to be bent, a greater air pressure develops than in the area of the outflow openings 9, 9 '. This applies in particular to the air flow emerging from the lower outflow channels 4 obliquely in the direction of tape travel, which is directed into the wedge-shaped area between the arch wall 2 and the vertical section 5˝ of the tape 5. In this way, a continuous air cushion is generated in the room 3, which, in contrast to a perforated cylinder, cannot be impaired or destroyed by a local change in the tension in the band 5. The air escapes from space 3 practically only in the direction of the width of the strip material 5. Fluttering and wrinkling are avoided by friction of the outflowing air on the strip surface. In some cases, it is expedient to provide the row-shaped openings 6 in the arch wall 2, from which the compressed air 7 flows in the central region of curvature of the curved band section 5 '. The air streams flowing out of the upper channels 4 'against the running direction of the band 5 preferably have a lifting function for the horizontal starting section 5 ‴ of the curved band 5 and generate an additional pressure cushion in the widening area on the underside of the band section 5,, which makes contact of the band section 5 verhindert prevented with the upper end of the arch wall 2 and counteracts the decrease in pressure caused by the accelerated outflow of air from the middle pressure cushion in the band area 5 '.

Die Erfindung ist nicht auf die dargestellten Ausführungen beschränkt. So können die Öffnungen 9, 9′ bzw. die Kanäle 4, 4′ auch in Form von durchgehenden Schlitzen ausgebildet sein. Ferner kann der Ausströmquerschnitt einzelner oder aller Öffnungen z.B. durch Blenden verstellbar ausgeführt werden.The invention is not limited to the embodiments shown. So the openings 9, 9 'and the channels 4, 4' can also be formed in the form of continuous slots. Furthermore, the outflow cross-section of individual or all openings e.g. can be made adjustable by panels.
