Abstract
Description
Das Kühlpolster kann aus Wasser, Wasserdampf, Luft oder einem anderen flüssigen oder gasförmigen Medium, wie z. B. Kerosin, Stickstoff, bestehen. Das Gleit- und/oder Schutzpolster für das Flachmaterial kann aus Wasser, Luft, Öl einer Emulsion oder aus einem Inertgas bestehen. Ein flüssiges Polster hat vor allem den Vorteil, daß das Durchfedern von schwerem Bandmaterial auf die Linearantriebe gedämpft wird. Bei dünnem Warmband kann der gleiche Effekt durch ein gasförmiges Medium erzielt werden, das dann zusätzlich eine Schutzgasatmosphäre bildet. Das Polster für das Flachmaterial kann auch eine reine Gleitfunktion haben; es kann zusätzlich eine Schutzfunktion haben und sorgt im letzteren Fall dafür, daß z. B. an den empfindlichen Oberflächen von dünnem Warmband keine Kratzer auftreten als Folge des zeitweisen Aufliegens und Gleitens auf den Linearantrieben. The cooling pad can consist of water, water vapor, air or another liquid or gaseous medium, such as. B. kerosene, nitrogen, exist. The sliding and / or protective padding for the flat material can be made of water, Air, oil, an emulsion or an inert gas. A liquid cushion has the main advantage that the spring deflection of heavy strip material on the Linear drives is damped. The same effect can be achieved with thin hot strip a gaseous medium can be achieved, which then also has a protective gas atmosphere forms. The pad for the flat material can also have a pure sliding function; it can also have a protective function and, in the latter case, ensures that z. B. no scratches occur on the sensitive surfaces of thin hot strip as a result of temporarily resting and sliding on the linear drives.
Die Einrichtung kann ein flüssiges Medium abgeben, das in dem Bereich zwischen dem Flachmaterial und dem Linearantrieb verdampft, so daß für die Verdampfungswärme ein erheblicher Anteil der Strahlungswärme verwendet wird. Die Einrichtung kann zu diesem Zweck z. B. Wasser abgeben. Die Bildung eines Gleitpolsters ist dann von Wichtigkeit, wenn anstelle von einer oder mehreren Rollen des Rollgangs der Bandstraße Linearantriebe vorgesehen sind, so daß in diesem Bereich ein rollender Transport des Flachmaterials nicht möglich ist. Durch das Gas bzw. flüssige Medium wird ein Gleitpolster nach dem Aquaplaningprinzip gebildet. Dieses Medium hat insbesondere bei dünnen Warmbändern die Aufgabe, zu verhindern, daß die Warmbänder während des Transportes infolge der stets auftretenden Durchfederungen ein Kontaktieren der Oberfläche der Linearantriebe vornehmen, die zu Riefen bzw. Kratzern auf der Oberfläche des Bandmaterials führen würden. Bekanntlich sind solche Bänder für die weitere Verarbeitung, z. B. in der Automobilindustrie, nicht mehr brauchbar und müssen aussortiert werden. The device can dispense a liquid medium in the area evaporated between the flat material and the linear drive, so that for the heat of evaporation a significant proportion of the radiant heat is used. The facility can for this purpose z. B. Release water. The formation of a sliding pad is then of Importance if instead of one or more rollers of the conveyor belt roller table Linear drives are provided so that a rolling transport in this area of the flat material is not possible. The gas or liquid medium creates a Sliding pad formed according to the aquaplaning principle. This medium in particular has In the case of thin hot strips, the task is to prevent the hot strips from falling during the Transport as a result of the constant deflection, contacting the Make the surface of the linear drives that lead to grooves or scratches on the surface of the tape material would lead. As is well known, such tapes are for the further Processing, e.g. B. in the automotive industry, no longer usable and must be sorted out will.
Erfindungsgemäß weist die Einrichtung eine in der Ebene der Abdeckplatte des Linearantriebes angeordnete Abdeckung mit Austrittsöffnungen für ein flüssiges und/oder gasförmiges Medium auf. Hierbei muß sichergestellt werden, daß einerseits ein hinreichend starkes Polster gebildet wird, zum anderen muß auch sichergestellt werden, daß das Medium nicht eine Abkühlung des Flachmaterials im Sinne einer Gefügebeeinflussung bewirkt. According to the invention, the device has one in the plane of the cover plate the linear drive arranged cover with outlet openings for a liquid and / or gaseous medium. It must be ensured that on the one hand a sufficiently strong cushion is formed, on the other hand must also be ensured that the medium does not cool the flat material in the sense of influencing the structure causes.
Um ein gleichmäßiges Erzeugen des erfindungsgemäßen Polsters zu erreichen, sind in einer weiteren Ausgestaltung der Erfindung die Achsen der Austrittsöffnungen zur Oberfläche der Abdeckung derart geneigt angeordnet, daß das Flachmaterial durch seine Bewegung das Medium in den Bereich zwischen der Materialunterseite sowie der Abdeckplatte und der Abdeckung einzieht. Durch diese Maßnahmen wird erreicht, daß lediglich auf der Einlaufseite des Flachmaterials gasförmiges bzw. flüssiges Medium zwischen der Unterseite des Flachmaterials und den Linearantrieb einzuspeisen ist, das durch die Bewegung des Materials in den Spalt zwischen Flachmaterial und Linearantrieb eingesaugt wird. In order to achieve a uniform production of the cushion according to the invention, are in a further embodiment of the invention, the axes of the outlet openings arranged inclined to the surface of the cover that the flat material through its movement moves the medium into the area between the underside of the material and the Cover plate and the cover pulls in. Through these measures it is achieved that only gaseous or liquid medium on the inlet side of the flat material is to be fed between the underside of the flat material and the linear drive, by moving the material into the gap between the flat material and the linear drive is sucked in.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Abdeckung in die Abdeckplatte des Linearantriebes integriert, so daß hierdurch eine Baueinheit geschaffen ist. According to a further advantageous embodiment of the invention is the cover integrated into the cover plate of the linear drive, so that this a structural unit is created.
Gemäß einer noch weiteren vorteilhaften Ausgestal- tung der Erfindung weist die Abdeckung auf der Einlaufseite des Flachmaterials zum Abweisen der Kante des Flachmaterials in Transportrichtung eine Abschrägung auf, so daß bei einer etwaigen Durchfederung des ankommenden Flachmaterials (Skibildung) ein Stau des Flachmaterials nicht eintreten kann. According to yet another advantageous embodiment device of the invention has the cover on the inlet side of the flat material to reject the edge of the flat material in the transport direction on a bevel, so that with a possible Suspension of the incoming flat material (ski formation) a jam of the flat material cannot occur.
In einer noch weiteren Ausgestaltung der Erfindung sind die Abdeckung und der Linearantrieb als heb- und senkbare Einheit ausgebildet Dies ist insbesondere dann von Vorteil, wenn beispielsweise beim Transport von schwerem Material auf den Einsatz der Linearantriebe verzichtet wird und dafür Sorge getragen werden muß, daß durch die ankommende Vorderkante des Materials eine Beschädigung des Linearantriebes und der Abdeckung ausgeschlossen wird. In yet another embodiment of the invention, the cover and the linear drive is designed as a unit that can be raised and lowered. This is particularly important advantageous when, for example, when transporting heavy material on the Use of the linear drives is dispensed with and care must be taken that the incoming leading edge of the material will damage the linear drive and the cover is excluded.
