On the support drum a plurality of Bahnschneidmesser parallel to the axis of the drum are movably mounted at the same angular distance along the circumference of the support drum. These cutting knives are urged to cycle at the angular location or at a fraction of the orbital angle of the support drum where the cut is to be made, an extension or cutting stroke through the web from a laterally retracted home position to a side edge of the web opposite side edge of the web and then make a retraction movement back to the starting position.

Rotationsfördervorrichtung der eingangs genannten Art haben üblicherweise eine im Wesentlichen zylindrische Form mit einem zylinderförmigen Mantel, der einen, üblicherweise zylinderförmigen, Körper umgibt. In dem Mantel sind mehrere Unterdrucktaschen angeordnet, die mit einer Unterdruckquelle verbunden sind, so dass die zu fördernden Artikel, die sich mittelbar oder unmittelbar auf der Oberfläche des Mantels befinden, durch den in den Unterdrucktaschen ausgebildeten Unterdruck an den Mantel angesaugt und so mit dem Mantel gefördert werden können. Zur Förderung sind Rotationsfördervorrichtungen der eingangs genannten Art üblicherweise angetrieben und werden durch den Antrieb in eine Rotationsbewegung versetzt, um die Artikel in einer Rotationsrichtung zu fördern.Rotary conveyor of the type mentioned initially have a substantially cylindrical shape with a cylindrical shell, which surrounds a, usually cylindrical, body. In the jacket a plurality of vacuum pockets are arranged, which are connected to a vacuum source, so that the articles to be conveyed, which are located directly on the surface of the jacket, sucked by the negative pressure formed in the vacuum pockets to the jacket and so with the jacket can be promoted. To promote rotary conveyors of the type mentioned are usually driven and are offset by the drive in a rotational movement to promote the articles in a rotational direction.

Bei der Herstellung beispielsweise von Zigaretten mit unterschiedlichem Format, insbesondere unterschiedlichem Durchmesser und/oder unterschiedlicher Länge, sind die entsprechenden, formatrelevanten Komponenten einer Maschine einer tabakverarbeitenden Industrie, insbesondere Rotationfördervorrichtungen der eingangs genannten Art, an ein geändertes Format anzupassen, was häufig mit hohem Aufwand und daraus resultierenden langen Stillstandszeiten sowie hohen Kosten verbunden ist.In the production of, for example, cigarettes with different formats, in particular different diameters and / or different lengths, the corresponding, form-relevant components of a machine of a tobacco-processing industry, in particular rotary conveying devices of the type mentioned, are on adapting a modified format, which is often associated with high costs and resulting long downtime and high costs.

Es ist daher eine Aufgabe der vorliegenden Erfindung, eine Rotationsfördervorrichtung, einen Foliensatz sowie Verfahren der eingangs genannten Art bereitzustellen, die die Anpassung einer Rotationsfördervorrichtung bzw. einer Maschine der tabakverarbeitenden Industrie an Artikel unterschiedlichen Formats erleichtern. Es ist ferner eine Aufgabe der vorliegenden Erfindung, eine Rotationsfördervorrichtung, einen Foliensatz sowie Verfahren der eingangs genannten Art bereitzustellen, welche die Wartung und Instandsetzung, insbesondere die Reinigung, von Fördervorrichtungen in Maschinen der tabakverarbeitenden Industrie erleichtern.It is therefore an object of the present invention to provide a rotary conveyor, a foil set and methods of the type mentioned, which facilitate the adaptation of a rotary conveyor or a machine of the tobacco processing industry on articles of different formats. It is also an object of the present invention to provide a rotary conveyor, a foil set and methods of the type mentioned, which facilitate the maintenance and repair, in particular the cleaning, of conveyors in machines of the tobacco processing industry.

Diese Aufgabe wird gelöst durch eine Rotationsfördervorrichtung der eingangs genannten Art, die dadurch gekennzeichnet ist, dass auf dem Mantel eine Folie mit Befestigungsmitteln lösbar befestigt ist, wobei die Folie ausgebildet ist, auf ihrer dem Mantel abgewandten Seite die Artikel, insbesondere Artikel eines ersten Formats, zu fördern.This object is achieved by a rotary conveying device of the type mentioned, which is characterized in that on the jacket a film with fastening means is releasably secured, wherein the film is formed on its side facing away from the jacket, the article, in particular articles of a first format, to promote.

Der Erfindung liegt die Erkenntnis zugrunde, dass eine erhebliche Erleichterung der Anpassung einer Maschine der tabakverarbeitenden Industrie auf die Verarbeitung und Förderung von Artikeln unterschiedlichen Formats dadurch erreicht werden kann, dass auf einen Austausch vollständiger Rotationsfördervorrichtungen, die für die Förderung von Artikeln eines ersten Formats angepasst sind, durch andere Rotationsfördervorrichtungen, die auf die Förderung von Artikeln eines zweiten Formats angepasst sind, verzichtet wird. Der Erfindung liegt ferner die Erkenntnis zugrunde, dass die Anpassung einer Rotationsfördervorrichtung an ein bestimmtes Format zu fördernder Artikel dadurch erzielt werden kann, dass eine lösbar auf der Manteloberfläche der Rotationsfördervorrichtung angebrachte Folie zur Förderung der Artikel vorgesehen ist.The invention is based on the recognition that a considerable facilitation of the adaptation of a machine of the tobacco processing industry to the processing and conveying of articles of different formats can be achieved by the fact that an exchange of complete rotary conveyors, which are adapted for the promotion of articles of a first format , is dispensed with by other rotary conveyors adapted to convey articles of a second format. The invention is further based on the finding that the adaptation of a rotary conveying device to a specific format to be conveyed article can be achieved that a releasably mounted on the mantle surface of the rotary conveyor device film is provided to promote the article.

Unter einer Folie ist ein bahn-, blatt-, bzw. plattenförmiges, vorzugsweise flexibles, Element zu verstehen. Beispielsweise kann die Folie als dünnes Blech mit einer Dicke von weniger als 1 mm ausgebildet sein. Besonders bevorzugt ist eine Dicke der Folie zwischen 0,1 - 0,8 mm.Under a film is a web, sheet, or plate-shaped, preferably flexible, element to understand. For example, the film may be formed as a thin sheet having a thickness of less than 1 mm. Particularly preferred is a thickness of the film between 0.1 - 0.8 mm.

Die Folie ist erfindungsgemäß ausgebildet, auf ihrer dem Mantel abgewandten Seite die Artikel der tabakverarbeitenden Industrie zu fördern. Dazu weist die Folie vorzugsweise auf ihrer dem Mantel abgewandten Seite eine im Wesentlichen glatte, zylindrische Oberfläche auf, d. h. eine Oberfläche ohne nach außen vorstehende Schnittkanten oder dergleichen.The film is inventively designed to promote on its side facing away from the coat the articles of the tobacco processing industry. For this purpose, the film preferably has a substantially smooth, cylindrical surface on its side facing away from the jacket on, ie a surface without outwardly projecting cut edges or the like.

Die Folie ist auf dem Mantel mit Befestigungsmitteln lösbar befestigt, d. h. die Folie kann von der Rotationsfördervorrichtung abgenommen und durch eine andere Folie ersetzt werden. Diese andere Folie kann dann ebenfalls lösbar wieder auf dem Mantel befestigt werden und ist ebenfalls ausgebildet, auf ihrer dem Mantel abgewandten Seite Artikel der tabakverarbeitenden Industrie zu fördern; im Gegensatz zur ersten Folie ist eine solche zweite Folie jedoch vorzugsweise an Artikel mit einem anderen Format angepasst.The film is releasably secured to the shell with fasteners, d. H. the film can be removed from the rotary conveyor and replaced with another film. This other film can then also be releasably secured back on the jacket and is also designed to promote on its side facing away from the jacket articles of the tobacco processing industry; however, unlike the first film, such a second film is preferably adapted to articles of a different format.

Auf diese Weise ist es möglich, die Rotationsfördervorrichtung an unterschiedliche Formate von zu fördernden Artikeln anzupassen, ohne den Körper und den Mantel der Rotationsfördervorrichtung austauschen zu müssen. Die lösbare Befestigung der Folie auf dem Mantel ermöglicht es, durch Lösen der Befestigungsmittel den Austausch der Folie gegen eine andere Folie leicht und wiederholbar vorzunehmen.In this way it is possible to adapt the rotary conveyor to different formats of articles to be conveyed without having to replace the body and the jacket of the rotary conveyor. The releasable attachment of the film on the jacket makes it possible to easily and repeatably replace the film with another film by loosening the fastening means.

Neben einem Austausch der Folie auf ein anderes Format von zu fördernden Artikeln ermöglicht die Erfindung auch eine leichtere Wartung bzw. Instandsetzung, insbesondere Reinigung der Rotationsfördervorrichtung: Durch Lösen der Befestigung der Folie auf dem Mantel und Ausbau der Folie aus der Rotationsfördervorrichtung kann die Folie, beispielsweise von Leimrückständen, gereinigt werden oder bei Bedarf anderweitig gewartet oder bei zunehmenden und kritischen Verschleiß oder einer Beschädigung durch eine andere, gleichartige Folie ersetzt werden. Es können zusätzlich die Vakuumtaschen im Trommelmantel leichter gereinigt werden.In addition to an exchange of the film to another format of articles to be conveyed, the invention also allows easier maintenance or repair, in particular cleaning the rotary conveyor: By loosening the attachment of the film on the jacket and removing the film from the rotary conveyor, the film, for example of glue residues, cleaned or otherwise serviced if necessary or replaced with increasing and critical wear or damage by another similar film. In addition, the vacuum pockets in the drum shell can be cleaned more easily.

Der Austausch lediglich der Folie anstelle der gesamten Rotationsfördervorrichtung ermöglicht einerseits eine schnellere Durchführung eines Formatwechsels oder einer Wartung bzw. Instandsetzung und führt damit zu geringeren Stillstandzeiten sowie andererseits eine Verringerung der Kosten, da die Folie einen deutlich geringeren Materialeinsatz erfordert als eine Rotationsfördervorrichtung.The replacement of only the film instead of the entire rotary conveyor allows on the one hand faster format change or maintenance or repair and thus leads to lower downtime and on the other hand, a reduction in costs, since the film requires a significantly lower material usage than a rotary conveyor.

Ein weiterer Vorteil der erfindungsgemäßen Rotationsfördervorrichtung ergibt sich dadurch, dass als Ersatz- oder Austauschteil lediglich Folien vorgehalten werden müssen, die in der Lagerhaltung deutlich platzsparender sind als Rotationsfördervorrichtungen im Ganzen.Another advantage of the rotary conveyor according to the invention results from the fact that as a replacement or replacement part only films must be kept, which are significantly more space-saving in storage than rotary conveyors as a whole.

Ein weiterer Vorteil der erfindungsgemäßen Rotationsfördervorrichtung ist es, dass die erfindungsgemäße Rotationsfördervorrichtung ebenso mit weiteren Komponenten einer Maschine der tabakverarbeitenden Industrie zusammenwirken kann wie aus dem Stand der Technik bekannter Rotationsfördervorrichtungen. Daher ist es möglich, in bestehenden Maschinen der tabakverarbeitenden Industrie Rotationsfördervorrichtungen gemäß dem Stand der Technik durch erfindungsgemäße Rotationsfördervorrichtungen auszutauschen und auf diese Weise die Vorteile der erfindungsgemäßen Rotationsfördervorrichtungen auch in bereits existierenden Maschinen der tabakverarbeitenden Industrie nutzen zu können.Another advantage of the rotary conveyor device according to the invention is that the rotary conveyor device according to the invention can also interact with other components of a machine of the tobacco processing industry as known from the prior art rotary conveyor devices. Therefore, it is possible to exchange in existing machines of the tobacco processing industry rotary conveyors according to the prior art by inventive rotary conveyors and in this way to be able to use the advantages of the rotary conveyors according to the invention in already existing machines of the tobacco processing industry.

Die Vorteile der erfindungsgemäßen Rotationsfördervorrichtung und ihrer Fortbildungen kommen insbesondere auch bei einer Ausbildung der Rotationsfördervorrichtung als Saugwalze zur Geltung. Saugwalzen kommen vorzugsweise zum Einsatz, um bahn- oder blattförmige Artikel der tabakverarbeitenden Industrie, wie insbesondere Filterbelagpapierbahnen oder Filterbelagpapierstreifen, zu fördern. Dabei ist es insbesondere bevorzugt, dass die Unterdruckdurchlässe der Folie auf das Format, das heißt die Abmessungen, der zu fördernden blattförmigen Artikel abgestimmt sind. Beispielsweise können die Unterdruckdurchlässe als eine Vielzahl von ein Lochbild bildende Ausnehmungen oder Bohrungen angeordnet sein. Bevorzugt ist, dass zwischen den Unterdruckdurchlässen, auf denen die zu fördernden blattförmigen Artikel angeordnet sind, Bereiche ohne Unterdruckdurchlässe der Folie ausgebildet sind, auf denen keine blattförmigen Artikel gefördert werden, so dass die geförderten blattförmigen Artikel in Umfangsrichtung voneinander beabstandet sind.The advantages of the rotary conveyor device according to the invention and its further developments are particularly effective in a design of the rotary conveyor as a suction roller. Suction rolls are preferably used to promote sheet or sheet-shaped articles of the tobacco processing industry, in particular filter cover paper webs or filter cover paper strips. It is particularly preferred that the vacuum passages of the film on the format, that is, the dimensions of the sheet-shaped article to be conveyed are tuned. For example, the vacuum passages may be arranged as a plurality of holes or holes forming a hole image. It is preferred that between the vacuum passages, on which the sheet-like articles to be conveyed are arranged, areas are formed without vacuum passages of the film on which no sheet-like articles are conveyed, so that the conveyed sheet-like articles are circumferentially spaced from each other.

In einer alternativen Ausführungsform ist die Rotationsfördervorrichtung dadurch gekennzeichnet, dass die Artikel stabförmig ausgebildet sind und die Rotationsfördervorrichtung als Fördertrommel ausgebildet ist, wobei vorzugsweise die Folie Aufnahmen aufweist, die ausgebildet sind, die stabförmigen Artikel auf einer dem Mantel abgewandten Seite aufzunehmen.In an alternative embodiment, the rotary conveyor device is characterized in that the articles are rod-shaped and the rotary conveyor is designed as a conveyor drum, wherein preferably the film has receptacles which are adapted to receive the rod-shaped article on a side facing away from the jacket.

Die Vorteile der erfindungsgemäßen Rotationsfördervorrichtungen und ihrer Fortbildungen kommen insbesondere auch bei der Ausbildung der Rotationsfördervorrichtung als Fördertrommel, die stabförmige Artikel, wie Tabakstöcke, Filterstäbe oder Zigaretten fördert, zur Geltung.The advantages of the rotary conveying devices according to the invention and their further developments are particularly evident in the design of the rotary conveying device as a conveying drum, which promotes rod-shaped articles, such as tobacco sticks, filter rods or cigarettes.

Zur Förderung der stabförmigen Artikel weist die Folie vorzugsweise Aufnahmen zur Aufnahme der stabförmigen Artikel auf eine dem Mantel abgewandten Seite auf, die als nach außen geöffnete Mulden oder Ausnehmungen in der Folie ausgebildet sind.To promote the rod-shaped article, the film preferably has receptacles for receiving the rod-shaped articles on a side facing away from the jacket, which are formed as outwardly open troughs or recesses in the film.

Die Aufnahmen können unterschiedlich ausgestaltet sein: Als Mulden ausgebildete Aufnahmen können auf der dem Mantel abgewandten Seite der Folie beispielsweise durch Aufschweißen oder Kleben aufgebracht sein. Die Mulden können auch durch Umformen oder Einprägen in der Folie ausgebildet sein.The recordings can be designed differently: Trays formed as depressions can, for example, be on the side of the film facing away from the jacket be applied by welding or gluing. The troughs can also be formed by forming or embossing in the film.

In einer alternativen Ausführungsform sind die Aufnahmen Ausnehmungen in der Folie, wobei die Ausnehmungen vorzugsweise rechteckförmig ausgebildet sind. Solche Ausnehmungen können beispielsweise aus der Folie ausgestanzt sein. Dabei ist es insbesondere bevorzugt, wenn die quer zur Rotationsrichtung ausgerichteten Kanten der Ausnehmungen angefast oder abgeschrägt sind. Dies hat den Vorteil, dass die zu fördernden Artikel besonders schonend in den Ausnehmungen aufgenommen werden können. Insbesondere wenn es sich bei den Artikeln um Tabakstöcke oder Zigaretten handelt ist dies vorteilhaft, um die Qualität der Artikel nicht negativ zu beeinflussen.In an alternative embodiment, the receptacles are recesses in the film, wherein the recesses are preferably formed rectangular. Such recesses may for example be punched out of the film. It is particularly preferred if the aligned transversely to the direction of rotation edges of the recesses are chamfered or bevelled. This has the advantage that the articles to be conveyed can be taken up particularly gently in the recesses. In particular, when the articles are tobacco sticks or cigarettes, this is advantageous so as not to adversely affect the quality of the articles.

Bei einer weiteren alternativen Ausführungsform der vorliegenden Erfindung ist die, bevorzugt im Wesentlichen aus Blech bestehende, Folie als geschlossener Ring ausgebildet. Dabei weist der geschlossene Ring bevorzugt einen Innendurchmesser auf, der kleiner ist als der Außendurchmesser des Mantels, bevorzugt etwa 0,25 bis etwa 0,75mm kleiner, weiter bevorzugt etwa 0,5mm kleiner. Durch diese beiden, vorgenannten Varianten dieser Ausführungsform wird erfindungsgemäß die Befestigung und der Wechsel der Folie noch einfacher und kostengünstiger gestaltet. Dadurch dass der innere Umfang des Rings ein gewisses Maß kleiner ist als der Umfang des Trommelkörpers ergibt sich bei der Montage einer derart als Ring ausgebildeten Folie eine Dehnung in den Mulden. Dadurch wird eine Vorspannung erzeugt, die das derart ausgebildete Muldenblech vorteilhaft auf dem Trommelkörper fixiert. Auch bei dieser Ausführungsform kann die Positionierung der derart als Blech ausgebildeten Folien mit Hilfe von Stiften vorgenommen werden.In a further alternative embodiment of the present invention, the foil, which preferably consists essentially of sheet metal, is formed as a closed ring. In this case, the closed ring preferably has an inner diameter which is smaller than the outer diameter of the shell, preferably about 0.25 to about 0.75 mm smaller, more preferably about 0.5 mm smaller. By means of these two aforementioned variants of this embodiment, according to the invention, the attachment and the change of the film are rendered even simpler and less expensive. The fact that the inner circumference of the ring is a certain degree smaller than the circumference of the drum body results in the assembly of such a ring formed as a film, an expansion in the wells. As a result, a bias voltage is generated which advantageously fixes the tray plate formed in this way on the drum body. Also in this embodiment, the positioning of the sheets thus formed as a sheet can be made by means of pins.

Bei einer weiteren Variante der vorstehenden bevorzugten Ausführungsform der vorliegenden Erfindung wird der geschlossene Ring an mindestens einer seiner der jeweiligen Stirnseite zugewandten Ränder angefast, bevorzugt mit einer dem Mantel des Trommelkörpers zugewandten Fase. Auf diese Weise ist es problemlos möglich, die als geschlossener Ring ausgebildete Blechfolie auf den Trommelkörper aufzudrücken bzw. aufzuschieben.In a further variant of the above preferred embodiment of the present invention, the closed ring is chamfered on at least one of its edges facing the respective end face, preferably with a chamfer facing the shell of the drum body. In this way, it is easily possible to push or slide the formed as a closed ring metal foil on the drum body.

Bei einer weiteren bevorzugten Ausführungsform der vorliegenden Erfindung ist der Mantel an mindestens einer der jeweiligen Stirnseite und seinem Umfang zugewandten Umfangskante angefast. Auf diese Weise lässt sich die erfindungsgemäße Folie, insbesondere wenn sie als geschlossener, bevorzugt aus Blech gefertigter, Ring ausgebildet ist, leicht auf den Trommelkörper aufdrücken bzw. aufschieben.In a further preferred embodiment of the present invention, the jacket is chamfered on at least one peripheral edge facing the respective end face and its circumference.

Bei einer weiteren bevorzugten Ausführungsform der Erfindung wird die Folie als Blech ausgebildet, wobei auf der dem Mantel abgewandten Seite der Folie als Mulden ausgebildete Aufnahmen vorgesehen sind, deren geöffnete Seiten vom Mantel abgewandt sind, wobei es sich bei den Mulden um in radial von der Folie abstehende Stege eingefräste Mulden handelt. Die Stege können bevorzugt durch Ätzen eines zur Herstellung der Folie verwendeten Blechrohlings gebildet werden. Dabei wird bevorzugt ein Blechrohling außerhalb der für die Stege vorgesehenen Bereiche von einer Grunddicke heruntergeätzt auf die schließlich verbleibende Dicke der Blechfolie außerhalb der für die Stege vorgesehenen Bereiche. Beispielsweise kann für den Blechrohling eine ursprüngliche Blechdicke von 3mm verwendet werden, die außerhalb der Stege auf eine geätzte Blechdicke von 0,15mm heruntergeätzt wird. Die Stege verbleiben daher integral außerhalb des geätzten Bereiches mit dem Blechring verbunden stehen und können anschließend durch einen Fräsvorgang mit erfindungsgemäßen Mulden versehen werden. Einer der Vorteile dieser Ausführungsform der aus einem Blechrohling heraus geätzten Stege besteht darin, dass auf diese Weise keine stirnseitige Abdichtung der Mulden gegen Nebenluft mehr erforderlich ist, da durch das vorgenannte Ausbilden der Stege mittels Ätztechnik bereits eine Abdichtung gegen Nebenluft erzeugt wird.In a further preferred embodiment of the invention, the film is formed as a sheet, being provided on the side facing away from the jacket of the film as wells receptacles are provided, the open sides facing away from the jacket, wherein it is at the troughs in radially of the film protruding ridges milled depressions is. The webs may preferably be formed by etching a sheet metal blank used to produce the film. In this case, preferably, a sheet metal blank outside the areas provided for the webs is etched down from a base thickness onto the finally remaining thickness of the metal sheet outside the areas provided for the webs. For example, for the sheet metal blank, an original sheet thickness of 3 mm can be used, which is etched down outside the bars to an etched sheet thickness of 0.15 mm.

Die in den Figuren 1 bis 10 abgebildete Ausführungsform einer erfindungsgemäßen Rotationsfördervorrichtung 100 ist als Fördertrommel zum Fördern stabförmig ausgebildeter Artikel 400, 410, 420 ausgebildet. Wie in den Figuren 1, 2 und 6 zu erkennen ist, ist die Rotationsfördervorrichtung 100 ausgebildet, Artikel in zwei parallelen Förderlinien zu fördern. Fig. 3 stellt einen Querschnitt durch die erste Förderlinie der Rotationsfördervorrichtung 100 gemäß Fig. 1 dar, Fig. 5 einen Querschnitt durch die zweite Förderlinie der Rotationsfördervorrichtung 100 gemäß Fig. 1. Im Folgenden beschriebene Merkmale, Ausführungsdetails und Vorteile für eine Förderlinie gelten, soweit nicht anders angegeben, für eine zweite oder weitere Förderlinie gleichermaßen.The in the FIGS. 1 to 10 illustrated embodiment of a rotary conveyor device 100 according to the invention is designed as a conveyor drum for conveying rod-shaped articles 400, 410, 420. As in the FIGS. 1 . 2 and 6 As can be seen, the rotary conveyor 100 is adapted to convey articles in two parallel conveyor lines. Fig. 3 FIG. 12 illustrates a cross-section through the first conveyor line of the rotary conveyor 100 according to FIG Fig. 1 represents, Fig. 5 a cross section through the second conveyor line of the rotary conveyor 100 according to Fig. 1 , Features, design details and advantages for a conveyor line described below apply equally to a second or further conveyor line, unless stated otherwise.

Die Rotationsfördervorrichtung 100 weist einen Körper 110 mit einem im Wesentlichen zylinderförmigen Mantel 120 auf, wobei der Mantel 120 mehrere Unterdrucktaschen 121 aufweist. Die Unterdrucktaschen 121 können durch Anschließen an eine Saugquelle (nicht dargestellt) mit einem Unterdruck beaufschlagt werden, um Artikel 400, 410, 420 anzusaugen. In den Fig. 4, 5 und 8 ist zu erkennen, dass die Unterdrucktaschen 121 zur äußeren Oberfläche des Mantels hin aufgeweitete Abschnitte 122 aufweisen.The rotary conveying device 100 has a body 110 with a substantially cylindrical jacket 120, wherein the jacket 120 has a plurality of vacuum pockets 121. The vacuum pockets 121 may be pressurized by connecting to a suction source (not shown) to draw articles 400, 410, 420. In the Fig. 4 . 5 and 8th It can be seen that the vacuum pockets 121 have flared portions 122 towards the outer surface of the shell.

In den Fig. 1-10 sind verschiedene Varianten von Folien 200, 210, 220, 230 dargestellt. Die Folien 200, 210, 220, 230 bestehen aus magnetisierbarem Metall und können auf dem Mantel 120 mit Befestigungsmitteln, die hier als Permanentmagnete 310 ausgebildet sind, lösbar befestigt werden. Die Permanentmagnete 310 sind gemäß Figuren 7 und 8 so angeordnet, dass sie mit der äußeren Oberfläche des Mantels 120 abschließen und mit der Außenfläche des Mantels 120 eine gemeinsame, glatte Oberfläche bilden. Sie können jedoch auch über die Mantelfläche herausragen oder leicht versenkt sein.In the Fig. 1-10 Different variants of films 200, 210, 220, 230 are shown. The films 200, 210, 220, 230 are made of magnetizable metal and can be releasably secured to the shell 120 with fastening means, which are here designed as permanent magnets 310. The permanent magnets 310 are according to FIGS. 7 and 8th arranged to terminate with the outer surface of the shell 120 and form a common, smooth surface with the outer surface of the shell 120. However, they can also protrude over the lateral surface or be slightly recessed.

Die Folien 200, 210, 220, 230 sind ausgebildet, auf ihrer dem Mantel 120 abgewandten Seiten 201, 211, 221, 231 die Artikel 400, 410, 420 zu fördern. Dazu weisen die Folien 200, 210, 220, 230 Aufnahmen 700, 710, 730, 800 auf, die sich zum einen in ihrer Ausbildung und Herstellung unterscheiden und sie zum anderen geeignet machen, Artikel 400, 410, 420 unterschiedlichen Formats aufzunehmen. Durch die lösbare Befestigung der Folien auf dem Mantel 120 mittels der Permanentmagnete 310 ist es möglich, die Folien 200, 210, 220, 230 einfach und schnell auszutauschen.The films 200, 210, 220, 230 are designed to convey the articles 400, 410, 420 on their sides 120, 211, 221, 231 facing away from the casing 120. For this purpose, the films 200, 210, 220, 230 receptacles 700, 710, 730, 800, which differ on the one hand in their design and manufacture and make them suitable on the other to take items 400, 410, 420 different format. By the releasable attachment of the films on the shell 120 by means of the permanent magnets 310, it is possible to easily and quickly replace the films 200, 210, 220, 230.

Die Folien 200, 210, 230 weisen als Mulden 700, 710, 730 ausgebildete Aufnahmen aus, deren geöffnete Seiten vom Mantel 120 abgewandt sind. In der in den Figuren 1 bis 5 dargestellten Varianten der Folien 200, 210 sind die Mulden 700, 710 durch Umformen bzw. Prägen in die Folien 200, 210 eingebracht. Unterschiedliche Tiefen bzw. Radien der Mulden 700, 710 können durch die Verwendung unterschiedlicher Umform- bzw. Prägewerkzeuge erzielt werden. Bei nur kleinen gewünschten Änderungen kann es ausreichen, ein Ausgangsmaterial mit einer veränderten Dicke zu wählen, so dass die beim Umformen bzw. Prägen auf dem gleichen Werkzeug entstehende Mulde eine andere Tiefe bzw. einen anderen Radius aufweist als eine Mulde einer auf dem gleichen Werkzeug hergestellten Folie mit einer anderen Dicke. Die Mulden 730 der in Fig. 10 dargestellten Folie 230 sind auf der dem Mantel abgewandten Seite der Folie 231 aufgebracht, beispielsweise durch Kleben oder Schweißen.The foils 200, 210, 230 have receptacles designed as depressions 700, 710, 730, whose open sides are remote from the casing 120. In the in the FIGS. 1 to 5 illustrated variants of the films 200, 210, the wells 700, 710 are introduced by forming or embossing in the films 200, 210. Different depths or radii of the troughs 700, 710 can be achieved by using different forming or embossing tools. With only small desired changes, it may be sufficient to choose a starting material with a different thickness, so that the cavity formed during the forming or embossing on the same tool has a different depth or a different radius than a trough of a manufactured on the same tool Foil with a different thickness. The hollows 730 of in Fig. 10 shown film 230 are applied on the side facing away from the jacket of the film 231, for example by gluing or welding.

Die Mulden 700, 710, 730 weisen Unterdruckdurchlässe auf, die als in Reihe angeordnete Bohrungen 500, 530 oder als Langlöcher 510 ausgebildet sein können. Die Unterdruckdurchlässe 500, 510, 530 stehen mit den Unterdrucktaschen 121 in Fluidverbindung, so dass auf der dem Mantel abgewandten Seite 201, 211, 231 der Folien 200, 210, 230 die Artikel 400, 410 an die Folien 200, 210, 230 angesaugt werden können.The wells 700, 710, 730 have vacuum passages which may be formed as serially arranged bores 500, 530 or as elongated holes 510. The vacuum passages 500, 510, 530 are in fluid communication with the vacuum pockets 121, so that on the side facing away from the jacket 201, 211, 231 of the films 200, 210, 230, the articles 400, 410 are sucked to the films 200, 210, 230 can.

Die in den Figuren 6 bis 9 dargestellte Folie 220 weist rechteckförmige Ausnehmungen 800 als Aufnahmen aus, in denen Artikel 420 aufgenommen werden können. Vorzugsweise sind die queraxial zur Förderrichtung verlaufenden Kanten 801, 802 der Ausnehmungen 800 angefast oder abgeschrägt, um die Artikel 420 besonders schonend aufnehmen zu können, was sich positiv auf die Qualität der Artikel 420 und der daraus hergestellten Endprodukte auswirkt. Die Ausnehmungen 800 stehen mit den Unterdrucktaschen 121 in Fluidverbindung, so dass auf der dem Mantel abgewandten Seite 221 der Folie 220 die Artikel 420 an die Folie 220 angesaugt werden können.The in the FIGS. 6 to 9 illustrated film 220 has rectangular recesses 800 as recordings in which article 420 can be added. Preferably, the edges 801, 802 of the recesses 800 extending transversely to the conveying direction are chamfered or chamfered in order to be able to receive the articles 420 with particular care, which has a positive effect on the quality of the articles 420 and the end products produced therefrom. The recesses 800 are in fluid communication with the vacuum pockets 121, so that the articles 420 can be sucked onto the film 220 on the side 221 of the film 220 facing away from the jacket.

Die Unterdrucktaschen 121 und die aufgeweiteten Abschnitte 122 sind vorzugsweise derart ausgebildet und insbesondere breit genug, um Artikel 400, 410, 420 unterschiedlichen Formats ansaugen zu können.The vacuum pockets 121 and the flared portions 122 are preferably formed and, in particular, wide enough to be able to aspirate articles 400, 410, 420 of different sizes.

Die Folien bzw. der Mantel weisen vorzugsweise weiterhin Positionierungsmittel auf, die in den Fig. 1, 2, 6 und 10 als Stifte 600 dargestellt sind, die durch Eingriff in entsprechende Positionierungsöffnungen (für Folie 220 in Fig. 9 mit 223 bezeichnet) die jeweilige Folie auf dem Mantel 120 in einer vorbestimmten Position festlegen können.The films or the jacket preferably further comprise positioning means which are in the Fig. 1 . 2 . 6 and 10 are shown as pins 600, which by engaging in corresponding positioning holes (for film 220 in Fig. 9 designated 223) can set the respective film on the shell 120 in a predetermined position.

Wie in den Figuren 9 und 10 zu erkennen ist, weisen die Folien 220, 230 vorzugsweise einen Spalt 224, 234 auf, der die Montage bzw. Demontage der Folien 220, 230 erleichtert.As in the Figures 9 and 10 it can be seen, the films 220, 230 preferably have a gap 224, 234, which facilitates the assembly or disassembly of the films 220, 230.

Bei einer, nicht dargestellten, alternativen Ausführungsform zu der in Figur 10 dargestellten Variante besteht die Folie 230 aus Blech und ist als geschlossener Ring ausgebildet. Dabei weist der geschlossene Ring einen Innendurchmesser auf, der kleiner ist als der Außendurchmesser des Mantels, bevorzugt etwa 0,25 bis etwa 0,75 mm kleiner, weiter bevorzugt etwa 0,5 mm kleiner. Dadurch dass der innere Umfang der als Ring ausgebildeten Folie 230 ein gewisses Maß kleiner ist als der Umfang des in Figur 10 nicht dargestellten Trommelkörpers ergibt sich bei der Montage einer derart als Ring ausgebildeten Folie eine Dehnung in den Mulden beim Aufziehen des Rings auf den Trommelkörper.In one, not shown, alternative embodiment to the in FIG. 10 illustrated variant, the film 230 is made of sheet metal and is designed as a closed ring. In this case, the closed ring has an inner diameter which is smaller than the outer diameter of the shell, preferably about 0.25 to about 0.75 mm smaller, more preferably about 0.5 mm smaller. The fact that the inner circumference of the film 230 formed as a ring is somewhat smaller than the circumference of the in FIG. 10 not shown drum body results in the assembly of such a film formed as a ring an elongation in the wells when mounting the ring on the drum body.

Durch die dadurch erzeugte Vorspannung wird das als geschlossener Ring ausgebildete Blech 230 auf dem Trommelkörper fixiert. Auch bei dieser Variante kann die Positionierung der Folie 230 auf dem Trommelkörper mit Hilfe von Stifte vorgenommen werden.Due to the bias generated thereby, the formed as a closed ring plate 230 is fixed on the drum body. Also in this variant, the positioning of the film 230 can be made on the drum body by means of pins.

Bei einer weiteren, ebenfalls nicht dargestellten Variante der vorstehenden Ausführungsformen wird der geschlossene Ring an mindestens einer seiner der jeweiligen Stirnseite zugewandten Ränder mit einer dem Mantel des Trommelkörpers zugewandten Fase angefast.In a further, likewise not shown variant of the above embodiments, the closed ring is chamfered on at least one of its edges facing the respective end side with a facing the jacket of the drum body bevel.

Bei einer weiteren Variante ist der Mantel des Trommelkörpers an mindestens einer der jeweiligen Stirnseite und seinem Umfang zugewandten Umfangskante angefast.In a further variant, the jacket of the drum body is chamfered on at least one peripheral edge facing the respective end face and its circumference.

Bei einer weiteren Variante der in Figur 10 dargestellten Folie 230 ist die Folie 230 aus Blech hergestellt. Die Stege 730 sind durch Ätzen eines zur Herstellung der Folie verwendeten Blechrohlings gebildet worden. Dabei wird ein Blechrohling außerhalb der für die Stege vorgesehenen Bereiche von einer Grunddicke herunter geätzt auf die schließlich verbleibende Dicke der Blechfolie außerhalb der für die Stege vorgesehenen Bereiche. Dabei wird für den Blechrohling eine ursprüngliche Blechdicke von 3 mm verwendet, die außerhalb der Stege auf eine geätzte Blechdicke von 0,15 mm herunter geätzt wird. Die Stege verbleiben außerhalb des geätzten Bereiches integral mit dem Blechring verbunden stehen und werde anschließend durch Fräsen mit den Mulden 730 versehen.In another variant of in FIG. 10 film 230 shown, the film 230 is made of sheet metal. The webs 730 have been formed by etching a sheet metal blank used to produce the film. In this case, a sheet metal blank outside of the intended areas for the webs of a base thickness is etched down to the final remaining thickness of the sheet metal foil outside the intended areas for the webs. In this case, an original sheet thickness of 3 mm is used for the sheet metal blank, which is etched outside the webs down to an etched sheet thickness of 0.15 mm down. The webs remain outside the etched area integrally connected to the sheet metal ring stand and will then be provided by milling with the wells 730.

In der in den Figuren 11 bis 16 dargestellten Ausführungsform der erfindungsgemäßen Rotationsfördervorrichtung 1100 handelt es sich um eine Saugwalze mit einem Körper 1110 und einem im Wesentlichen zylinderförmigen Mantel 1120 sowie einem Drehgriff 1101.In the in the FIGS. 11 to 16 illustrated embodiment of the rotary conveyor 1100 according to the invention is a suction roll with a body 1110 and a substantially cylindrical shell 1120 and a rotary handle 1101st

Auf dem Mantel 1120 ist eine Folie angeordnet, die, wie in den Figuren 11, 12 und 14 zu erkennen ist, aus mehreren Foliensegmenten 1210 besteht und ausgebildet ist, auf ihrer dem Mantel 1120 abgewandten Seite blattförmige Artikel, beispielsweise Filterpapierstreifen, zu fördern. Der Mantel 1120 weist mehrere Unterdrucktaschen 1121 auf, die durch Anschließen an eine Saugquelle (nicht dargestellt) mit einem Unterdruck beaufschlagt werden können, um Artikel auf der dem Mantel 1120 abgewandten Seite der Folie bzw. der Foliensegmente 1210 ansaugen zu können.On the jacket 1120 a film is arranged, which, as in the Figures 11 . 12 and 14 can be seen, consists of several film segments 1210 and is formed on its side facing away from the jacket 1120 sheet-shaped article, such as filter paper strip to promote. The jacket 1120 has a plurality of vacuum pockets 1121, which can be acted upon by connecting to a suction source (not shown) with a negative pressure to suck articles on the side facing away from the jacket 1120 of the film or the film segments 1210 can.

Die Foliensegmente 1210 sind aus magnetisierbarem Metall ausgebildet und über als Permanentmagnete 1310a,b,c ausgebildete Befestigungsmittel lösbar an dem Mantel 1220 befestigt. Die Permanentmagnete 1310a,b,c sind ringförmig ausgebildet und so angeordnet, dass sie mit der äußeren Oberfläche des Mantels 1120 abschließen und mit der Außenfläche des Mantels 1120 eine gemeinsame, annähernd glatte Oberfläche bilden.The foil segments 1210 are formed of magnetizable metal and releasably secured to the shell 1220 via fasteners formed as permanent magnets 1310a, b, c. The permanent magnets 1310a, b, c are annular and arranged to terminate with the outer surface of the shell 1120 and form a common, nearly smooth surface with the outer surface of the shell 1120.

Die Foliensegmente 1210 weisen Bohrungen als Unterdruckdurchlässe auf, die in Form eines Lochbildes 1212 angeordnet sind. Diese Unterdruckdurchlässe in Form eines Lochbildes 1212 stehen mit im Mantel 1120 ausgebildeten Unterdrucktaschen 1221 in Fluidverbindung. Die Unterdrucktaschen 1221a,b können, wie in Fig. 12 zu erkennen ist, unterschiedlich ausgebildet sein. Wie auch bei der zuvor beschriebenen Fördertrommel-Ausführungsform ist in der Saugwalzen-Ausführungsform die Ausbildung der Vakuumtaschen 1221a,b jedoch formatunabhängig, d.h. eine Anpassung der Rotationsfördervorrichtung 1100 an unterschiedliche Formate zu fördernder Artikel kann allein durch einen Austausch der Folie 1200 bzw. der Foliensegmente 1210, 1220 erfolgen.The film segments 1210 have holes as vacuum passages, which are arranged in the form of a hole pattern 1212. These vacuum passages in the form of a hole pattern 1212 are in fluid communication with vacuum pockets 1221 formed in the jacket 1120. The vacuum pockets 1221a, b can, as in Fig. 12 can be seen, be formed differently. However, as in the case of the previously described conveyor drum embodiment, the formation of the vacuum pockets 1221a, b in the suction roller embodiment is format-independent, ie an adaptation of the rotary conveyor 1100 to articles to be conveyed to different formats can be achieved solely by replacing the film 1200 or the film segments 1210 , 1220.

In Fig. 15 ist ein weiteres Segment 1220 für eine Rotationsfördervorrichtung 1100 gemäß der Fig. 11 und 12 dargestellt, die sich von dem in Fig. 14 dargestellten Segment 1210 durch ein auf ein anderes Format von Artikeln abgestimmtes Lochbild 1222 unterscheidet. Durch Austausch der Foliensegmente 1210 durch die Foliensegmente 1220 kann die Rotationsfördervorrichtung 1100 einfach, schnell und kostengünstig auf die Förderung andersformatiger Artikel umgestellt werden.In Fig. 15 is another segment 1220 for a rotary conveyor 1100 according to the Fig. 11 and 12 represented by the in Fig. 14 segment 1210 distinguished by a matched to a different format of articles hole pattern 1222. By replacing the film segments 1210 by the film segments 1220, the rotary conveyor 1100 can be easily, quickly and inexpensively converted to the promotion of different sized items.

Die Foliensegmente 1210, 1220 weisen Positionierungsöffnungen 1213, 1223 auf, mittels derer die Foliensegmente 1210, 1220 auf dem Mantel 1220 vorzugsweise durch Eingriff mit Positionierungsmitteln in einer bestimmten Position festgelegt werden können.The foil segments 1210, 1220 have positioning apertures 1213, 1223 by means of which the foil segments 1210, 1220 on the jacket 1220 can preferably be fixed in a specific position by engagement with positioning means.

Alternativ zu der Ausbildung der Folie als Foliensegmente 1210, 1220 wie in den Figuren 11, 12, 14 und 15 dargestellt, kann die Folie 1200 auch wie in Fig. 16 dargestellt einstückig ausgebildet sein und vorzugsweise einen Spalt 1204 zur Erleichterung der Montage aufweisen. Auch die Folie 1200 weist Unterdruckdurchlässe in Form eines Lochbilds 1202 und Positionierungsöffnungen 1203 auf und ist ausgebildet, auf ihrer dem Mantel 1120 abgewandten Seite 1201 blattförmige Artikel zu fördern.Alternatively to the formation of the film as film segments 1210, 1220 as in the Figures 11 . 12 . 14 and 15 as shown in FIG Fig. 16 shown integrally formed and preferably have a gap 1204 to facilitate assembly. The film 1200 also has vacuum passages in the form of a hole pattern 1202 and positioning openings 1203 and is designed to convey sheet-shaped articles on its side 1201 facing away from the jacket 1120.

Die Öffnungen 1205 in der Folie 1200 bzw. die Öffnungen 1215 zwischen den Foliensegmenten 1210 dienen als Schneidmesseröffnungen, in die Schneidmesser einer nicht dargestellten Schneidmesserwalze eingreifen können, um eine Endlosbahn eines blattförmigen Artikels in formatabhängige Streifen zu schneiden, die dann auf der dem Mantel 1220 abgewandten Seite 1201 der Folie 1200 bzw. auf der dem Mantel 1220 abgewandten Seite der Foliensegmente 1210, 1220 gefördert werden.The openings 1205 in the film 1200 and the openings 1215 between the film segments 1210 serve as cutting blade openings, can engage in the cutting blade of a cutting blade, not shown, to cut a continuous web of a sheet-like article in format-dependent strips, which then facing away from the jacket 1220 Page 1201 of the film 1200 or on the side facing away from the jacket 1220 of the film segments 1210, 1220 are promoted.
