Description

Die Erfindung betrifft eine Saugwalze zum Bewegen, insbesondere zur Beschleunigung oder Abbremsung von bogenförmigen Werkstücken. Derartige Saugwalzen werden beispielsweise eingesetzt, um einen von einem Stapel abgehobenen Bogen auf die Geschwindigkeit eines nachgeschalteten Förderbandes zu beschleunigen.The invention relates to a suction roll for moving, especially for accelerating or decelerating arcuate workpieces. Such suction rolls are for example, used to get one from a stack lifted bow at the speed of a accelerate downstream conveyor belt.

Der Erfindung liegt die Aufgabe zu Grunde, eine gattungsgemäße Saugwalze mit einem einfachen, kostengünstig herstellbaren und strömungstechnisch effizienten Aufbau zu schaffen.The invention is based on the object generic suction roller with a simple, inexpensive to manufacture and fluidic to create an efficient structure.

Zur Lösung dieser Aufgabe sind vorgesehen, ein Radkörper mit von einer Stirnseite ausgehenden, zumindest einseitig offenen, bei Rotation nacheinander an einem stirnseitig anliegenden, festen Saugluftkopf vorbeilaufenden Kanälen, sowie ein auf den Außenumfang des Radkörpers aufgebrachtes, umlaufendes Band mit nach außen weisenden Erhebungen und dazwischen befindlichen Vertiefungen, von denen jede mittels mindestens einer Verbindungsbohrung mit einem Kanal in Verbindung steht.To solve this problem, a wheel body is provided with starting from one end, at least on one side open, with rotation one after the other on one end adjacent, fixed suction air head passing channels, as well as one on the outer circumference of the wheel body applied, circumferential tape with outward-facing Surveys and in-between depressions, of which each with at least one connecting hole is connected to a channel.

Vorteilhaft besteht der Radkörper aus einem harten Kunststoff. Dieser läßt sich leicht zur Herstellung der Kanäle bohren. Vorzugsweise ist das Band als Zahnriemen ausgebildet, der aus einem elastischem Material gefertigt ist. Der Zahnriemen ist dann unter Spannung auf dem Radkörper aufgebracht. Bei dieser Ausgestaltung bedarf es keiner besonderen Mittel zur Festlegung des Zahnriemens auf dem Radkörper mehr. Bei Verwendung eines Zahnriemens ergeben sich auf höchst einfache Weise über die Riemenbreite durchgehende, nach außen weisende Zähne als Erhebungen und dazwischen befindliche Zahnlücken als Vertiefungen. Diese verlaufen zweckmäßig achsparallel, so dass sie durch einen angesaugten Bogen zuverlässig auf der ganzen Breite abgedeckt werden können.The wheel body advantageously consists of a hard one Plastic. This can easily be used to manufacture the channels drill. The belt is preferably a toothed belt formed, which is made of an elastic material. The toothed belt is then under tension on the wheel body upset. With this configuration, no one is required special means for fixing the timing belt on the Wheel center more. When using a timing belt in a very simple way across the belt width continuous teeth pointing outwards as elevations and tooth gaps between them as depressions. These are expediently axially parallel, so that they pass through a suction sheet reliably across the entire width can be covered.

Nach einer weiteren Ausgestaltung der Erfindung weisen die vorzugsweise durch die Zähne des Zahnriemens gebildeten Erhebungen des Bands einen etwa rechteckigen Querschnitt mit einer griffigen Außenfläche auf. Hierdurch kann eine große Auflagefläche für die zu beschleunigenden Werkstücke erreicht werden.According to a further embodiment of the invention, the preferably formed by the teeth of the toothed belt Elevations of the band have an approximately rectangular cross section with a non-slip outer surface. As a result, a large contact area for the workpieces to be accelerated can be achieved.

Vorteilhaft besteht der Radkörper aus einem Nabenteil mit einer angeformten Deckscheibe größeren Durchmessers an einer Stirnseite und einer an die andere Stirnseite des Nabenteils ansetzbaren Deckscheibe. Hierdurch läßt sich in einfacher Weise das vorzugsweise als Zahnriemen ausgebildete Band auf den Radkörper aufbringen. Gleichzeitig sind durch diese Maßnahme die Vertiefungen des Bands bzw. Zahnriemens bei der fertig montierten Saugwalze seitlich geschlossen, so dass sich in den einzelnen Vertiefungen ein starker Saugzug erreichen läßt.The wheel body advantageously consists of a hub part a molded cover plate of larger diameter one face and one to the other face of the Hub part attachable cover disc. This allows in simple way, preferably as a timing belt Apply trained tape to the wheel center. At the same time are the deepening of the tape or Toothed belt on the side of the fully assembled suction roll closed, so that in the individual wells strong suction can be reached.

Eine besonders einfache Ausgestaltung ergibt sich, wenn die ansetzbare Deckscheibe innen einen Ansatz mit einem dem Durchmesser des Nabenteils entsprechenden Durchmesser aufweist und mittels des elastischen vorzugsweise als Zahnriemen ausgebildeten Bands am Nabenteil festlegbar ist. Hierdurch können der Radkörper und die lose Deckscheibe mittels des Bands bzw. Zahnriemens mit einem einzigen Arbeitsschritt verbunden werden und es entfallen zusätzliche Befestigungsmittel.A particularly simple embodiment results if the attachable cover plate inside an attachment with a Diameter of the hub part corresponding diameter has and by means of the elastic preferably as Timing belt trained bands can be fixed on the hub part. This allows the wheel center and the loose cover plate by means of the belt or toothed belt with a single one Work step are connected and there are no additional Fasteners.

Der insgesamt mit 1 bezeichnete Radkörper weist ein Nabenteil 2 mit einer angeformten Deckscheibe 3 auf. Weiterhin ist eine an dem Nabenteil 2 ansetzbare weitere Deckscheibe 4 vorgesehen. Der Nabenkörper 2 und die Deckscheiben 3, 4 sind zweckmäßig als Drehteile aus einem harten Kunststoff, beispielsweise einem Polyuretan oder einem Kunstkautschuk, hergestellt. Der Durchmesser der Deckscheiben 3, 4 ist etwas größer als der Durchmesser des Nabenteils 2 ausgebildet, so dass sie einen über den Durchmesser des Nabenteils 2 hinausragenden Rand bilden. Die getrennt hergestellte Deckscheibe 4 weist einen umlaufenden Ansatz 5 auf, dessen Durchmesser gleich dem Durchmesser des Nabenteils 2 ist.The wheel body designated as a whole has 1 Hub part 2 with an integrally formed cover disk 3. Another is attachable to the hub part 2 Cover plate 4 is provided. The hub body 2 and the Cover disks 3, 4 are useful as turned parts from one hard plastic, for example a polyurethane or a synthetic rubber. The diameter of the Cover discs 3, 4 is slightly larger than the diameter of the Hub part 2 formed so that they over the Form the diameter of the hub part 2 protruding edge. The separately produced cover plate 4 has one circumferential approach 5, the diameter of which is equal to The diameter of the hub part 2 is.

Das Nabenteil 2 und die Deckscheiben 3, 4 weisen zentrale Bohrungen 6, 7 auf, die zur Aufnahme einer nicht dargestellten Antriebswelle dienen. Am Umfang des Nabenteils 2 mit der Deckscheibe 3 sind eine Vielzahl von Kanälen 8 vorgesehen, die einseitig zur Stirnseite der Deckscheibe 3 offen sind und parallel zur Achse A-A des Radkörpers 1 verlaufen. Wie Figur 2 zeigt, sind diese Kanäle dicht nebeneinander angeordnet. Beim dargestellten Ausführungsbeispiel sind die Kanäle als Sackbohrungen ausgeführt.The hub part 2 and the cover disks 3, 4 have central ones Bores 6, 7 on which do not hold a serve drive shaft shown. At the extent of Hub part 2 with the cover plate 3 are a variety of Channels 8 provided, the one side to the front of the Cover plate 3 are open and parallel to the axis A-A Wheel body 1 run. As Figure 2 shows, these are channels arranged close to each other. In the illustrated Embodiment are the channels as blind holes executed.

Vor der Stirnseite der Deckscheibe 3 ist ein fester Träger 9 angeordnet, der die Halterung für einen bis zur Stirnseite der Deckscheibe 3 reichenden und dort anliegenden Saugkopf 10 bildet. Der Saugluftkopf 10 ist in nicht näher dargestellter Weise an einen Sauglufterzeuger angeschlossen. Die freie Querschnittsfläche des Saugluftkopfes 10 ist so groß ausgeführt, dass sie die freien Querschnittsflächen zweier nebeneinander angeordneter Kanäle 8 überdeckt. Bei Rotation des Radkörpers 1 sind daher maximal drei Kanäle 8 mit Saugluft beaufschlagt. Dabei stehen die beiden äußeren Kanäle 8 zum Auf- bzw. Abbau des Saugzugs kurzfristig nur teilweise mit dem Sauglufterzeuger in Verbindung.In front of the front face of the cover plate 3 is a fixed support 9 arranged of the bracket for one to the front of the Cover plate 3 reaching and abutting suction head 10th forms. The suction air head 10 is not shown in FIG Way connected to a suction air generator. The free The cross-sectional area of the suction air head 10 is so large executed that the free cross-sectional areas of two adjacent channels 8 covered. At Rotation of the wheel body 1 is therefore a maximum of three channels 8 charged with suction air. The two outer ones stand Channels 8 for setting up or dismantling the induced draft only briefly partly in connection with the suction air generator.

Um das Nabenteil 2 und den Ansatz 5 ist, wie Figur 3 zeigt, zwischen den Deckscheiben 3, 4 ein insgesamt mit 11 bezeichneter Zahnriemen bei fertig montierter Saugwalze herumgelegt. Der Zahnriemen 11 ist aus einem elastischen Material gefertigt und weist Zähne 12 und dazwischen liegende Vertiefungen 13 auf. Die Zähne 12 weisen einen etwa rechteckigen Querschnitt auf. Ihre griffig, beispielsweise aufgerauht, ausgebildete Außenseite schließt zweckmäßig mit der Außenseite der Deckscheiben 3, 4 ab. Zur Montage der Saugwalze wird der Zahnriemen 11, der zweckmäßig endlos ausgebildet ist, unter Spannung auf das Nabenteil 2 aufgebracht. Anschließend wird die Deckscheibe 4 angesetzt. Around the hub part 2 and the shoulder 5, as shown in FIG. 3, a total of 11 between the cover disks 3, 4 Designated toothed belt with the suction roller fully assembled laid around. The toothed belt 11 is made of an elastic Material made and has teeth 12 and in between lying depressions 13. The teeth 12 have one rectangular cross section. Your handy, for example roughened, trained outside suitably includes the outside of the cover plates 3, 4. To assemble the Suction roller becomes the toothed belt 11, which is expediently endless is formed, under tension on the hub part 2 upset. Then the cover plate 4 is attached.

Dabei wird der Ansatz 5 unter den einen Randbereich des Zahnriemens 11 eingebracht, so dass der Zahnriemen auch die Deckscheibe 4 in der angesetzten Position hält.The approach 5 is under the one edge area of the Timing belt 11 introduced so that the timing belt too holds the cover plate 4 in the attached position.

Die Kanäle 8 sind so angeordnet, dass jeder Vertiefung 13 ein Kanal 8 zugeordnet ist. Nach Montage des Zahnriemens 11 und der Deckscheibe 4 werden durch den Zahnriemen und das Nabenteil 2 Bohrungen 14 eingebracht, die jede Vertiefung 13, mit einem Kanal 8 verbinden. Der Saugluftkopf 10 ist dabei so angeordnet, dass die Vertiefungen 13 an denen das bogenförmige Werkstück zur Anlage kommt, über die zugehörigen Bohrungen 14 und Kanäle 8 an den Sauglufterzeuger angeschlossen sind. Da die Vertiefungen 13 auf fünf Seiten abgeschlossen sind und auf der sechsten Seite ein bogenförmiges Werkstück aufliegt, wird das Werkstück durch einen sehr wirksamen Unterdruck an der Saugwalze 1 gehalten.The channels 8 are arranged so that each recess 13 is a Channel 8 is assigned. After installing the toothed belt 11 and the cover plate 4 are through the toothed belt and the hub part 2 holes 14 introduced, each Recess 13, connect to a channel 8. The suction air head 10 is arranged so that the recesses 13 on over which the arcuate workpiece comes to rest the associated holes 14 and channels 8 on the Suction air generators are connected. Since the recesses 13 are completed on five pages and on the sixth page an arcuate workpiece rests, the workpiece due to a very effective vacuum on the suction roller 1 held.

Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt. So können die Kanäle auch als durchgehende Bohrungen ausgeführt werden, die dann durch die angesetzte Deckscheibe am einen Ende abgeschlossen werden. Auch könnte die lose Deckscheibe durch andere bekannte Mittel am Nabenteil befestigt werden. Anstelle der Deckscheiben könnte auch der Zahnriemen mit seitlich umlaufenden Rändern versehen werden.The invention is not based on the illustrated Embodiment limited. So can the channels too run as through holes, which then through the attached cover plate at one end be completed. The loose cover could also be be attached to the hub portion by other known means. The timing belt could also be used instead of the cover plates side edges are provided.
