Abstract
Description
Die Erfindung betrifft eine Bandschleifmaschine mit einem Schleifband, das endlos über Rollen geführt ist, von denen wenigstens eine Antriebsrolle mit einem Antrieb verbunden ist und von denen wenigstens eine Spannrolle zur Ausübung einer Vorspannung auf das Schleifband verschiebbar gelagert und mit einer Spannvorrichtung gegen das Schleifband drückbar ist, wobei die Spannvorrichtung wenigstens zwei jeweils mit einem flexiblen, in seiner axialen Länge variablen zylindrischen Mantel versehene Luftfedern und eine die Verschiebung führende Führungseinrichtung aufweist und wobei die Spannrolle zum seitlichen Verschieben des Schleifbandes verschwenkbar angeordnet ist. folch eine Bandscheleifmaschine ist aus der
Schleifbänder an Bandschleifmaschinen, insbesondere Breitbänder, werden üblicherweise über drei Rollen geführt, die ein gleichschenkliges Dreieck bilden. Zwei der Rollen sind auf gleicher Höhe neben einem Druckbalken angeordnet, mit dem das Schleifband im Bereich zwischen den beiden Rollen gegen die Oberfläche des unterhalb der Rollen und des Druckbalkens geführten Werkstücks drückbar ist. Wenigstens eine der beiden Rollen ist angetrieben. Vorzugsweise sind die Rollen auf beiden Seiten des Druckbalkens angetrieben. Eine dritte Rolle befindet sich oberhalb des Druckbalkens und ist meist symmetrisch zu den beiden unteren Rollen angeordnet, um ein gleichschenkliges Dreieck zu bilden. Der Abstand der dritten Rolle zu den beiden Rollen ist wesentlich größer als der Abstand zwischen den beiden unteren Rollen, der im Wesentlichen durch die Breite des Druckbalkens bestimmt ist. Die obere Rolle wird in einer bekannten Konstruktion als Spannrolle ausgebildet. Hierzu ist die Spannrolle so gelagert und mit einer Spannvorrichtung verbunden, dass mit der Spannrolle das Schleifband gespannt wird, indem die Spannrolle mittels der Spannvorrichtung gegen das Schleifband, in der beschriebenen Konstruktion also nach oben, gedrückt wird. Wenn der Andruck durch die Spannvorrichtung konstant gehalten wird, entsteht eine konstante Bandspannung des Schleifbandes auch dann, wenn sich das Schleifband während des Gebrauchs längt.The invention relates to a belt grinding machine with a grinding belt which is endlessly guided over rollers, of which at least one drive roller is connected to a drive and of which at least one tensioning roller for exerting a bias on the grinding belt slidably mounted and can be pressed with a clamping device against the grinding belt wherein the tensioning device has at least two pneumatic springs each provided with a flexible cylindrical sleeve which is variable in its axial length, and a guide device guiding the displacement, and wherein the tensioning roller is arranged pivotable for lateral displacement of the grinding belt. Such a band shearing machine is from the
Sanding belts on belt sanding machines, in particular wide belts, are usually guided over three rollers which form an isosceles triangle. Two of the rollers are arranged at the same height next to a pressure bar, with which the grinding belt in the area between the two rollers can be pressed against the surface of the guided below the rollers and the pressure bar workpiece. At least one of the two rollers is driven. Preferably, the rollers are driven on both sides of the pressure beam. A third roll is located above of the pressure beam and is usually arranged symmetrically to the two lower rollers to form an isosceles triangle. The distance of the third roller to the two rollers is substantially greater than the distance between the two lower rollers, which is determined essentially by the width of the pressure beam. The upper roller is formed in a known construction as a tensioning roller. For this purpose, the tension roller is mounted and connected to a tensioning device that with the tension roller, the grinding belt is tensioned by the tension roller by means of the tensioning device against the grinding belt, in the construction described so up. If the pressure is kept constant by the tensioning device, a constant belt tension of the grinding belt arises even if the grinding belt lengthens during use.
Es ist ferner bekannt, bei einer Breitband-Schleifmaschine die obere Spannrolle um einen kleinen Winkel aus der Parallelität zu den anderen Rollen verschwenkbar anzuordnen, um das Schleifband während seines Umlaufs seitlich, d.h. in Längsrichtung der Spannrolle etwas zu verschieben. Dadurch wird erreicht, dass das Schleifband auch mit einer Seitwärtsbewegung über die Oberfläche des Werkstücks geführt wird. Damit diese Bewegung eine Hin- und Herbewegung ist, wird die Verschwenkung der Spannrolle oszillierend ausgeübt. Hierzu ist die Spannrolle mit einem oszillierenden Verschwenkantrieb versehen, der vorzugsweise an wenigstens einem Ende der Spannrolle angreift. Wenn die Spannvorrichtung in diesem Fall durch den Kolben eines Hydraulikzylinders gebildet ist, muss der Kolben innerhalb des Zylinders drehbar sein. Hierdurch entsteht eine erhebliche Belastung der Dichtung zwischen Hydraulikzylinder und Kolbenstange. Nachteilig ist ferner bei der Verwendung eines Hydraulikzylinders als Spannvorrichtung, dass dieser eine nicht unerhebliche Länge aufweisen muss. Wenn die Bandschleifmaschine mit einer zusätzlichen Führung für ein Drucklamellenband ausgestattet ist, das zwischen dem Schleifband und den unteren Rollen geführt wird, jedoch oberhalb des Druckbalkens mit einer eigenen Spannrolle versehen entsteht ein erhebliches Platzproblem, wenn die Bandschleifmaschine eine, beispielsweise durch Transportmöglichkeiten, vorgegebene Maximalhöhe nicht überschreiten soll.It is also known, in a broadband grinding machine, the upper idler to pivot about a small angle from the parallelism to the other rollers to arrange the sanding belt during its circulation laterally, ie to move something in the longitudinal direction of the tensioner. This ensures that the grinding belt is also guided with a sideways movement over the surface of the workpiece. For this movement is a reciprocating motion, the pivoting of the tensioner is oscillating. For this purpose, the tension roller is provided with an oscillating pivoting drive, which preferably acts on at least one end of the tensioning roller. If the tensioning device is formed by the piston of a hydraulic cylinder in this case, the piston must be rotatable within the cylinder. This creates a significant load on the seal between the hydraulic cylinder and the piston rod. Another disadvantage is the use of a hydraulic cylinder as a clamping device that this must have a considerable length. If the belt grinding machine is equipped with an additional guide for a pressure fins belt, which is guided between the sanding belt and the lower rollers, but provided above the pressure bar with its own tension roller creates a significant space problem when the belt grinder one, for example by transport options, given maximum height not should exceed.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Bandschleifmaschine so auszubilden, dass die benötigte Bandspannung und die Verschwenkung der Spannrolle mit einem geringen Platzbedarf realisierbar ist.The present invention is therefore based on the object, a belt grinding machine in such a way that the required belt tension and the pivoting of the tension roller can be realized with a small footprint.
Die Aufgabe wird erfindungsgemäß bei einer Bandschleifmaschine der eingangs erwähnten Art dadurch gelöst, dass die wenigstens zwei Luftfedern von einer Grundplatte getragen sind und über eine starre Trägerplatte mit der Spannrolle verbunden sind und dass die Führungseinrichtung zwischen den Luftfedern angeordnet ist und als Schwenkachse für die Verschwenkung der Spannrolle ausgebildet ist.The object is achieved in a belt grinding machine of the type mentioned above in that the at least two air springs are supported by a base plate and are connected by a rigid support plate with the tension roller and that the guide means is disposed between the air springs and as a pivot axis for the pivoting of Tension pulley is formed.
Bei der erfindungsgemäßen Bandschleifmaschine sind somit die Funktion "Führung" und "Verstellung" getrennt. Die Führung ist unproblematisch durch einen in einer Buchse gelagerten Führungsbolzen möglich, ohne dass dabei irgendwelche Dichtprobleme auftreten. Die Verstellung der Spannvorrichtung erfolgt mittels wenigstens einer Luftfeder, wobei in einer bevorzugten Ausführungsform wenigstens zwei Luftfedern verwendet werden, die symmetrisch zu der zwischen ihnen vorgesehenen Führungseinrichtung angeordnet sind.In the belt grinding machine according to the invention thus the function "guide" and "adjustment" are separated. The guide is possible without any problems by a guide pin mounted in a bush, without causing any sealing problems. The adjustment of the tensioning device by means of at least one air spring, wherein in a preferred embodiment, at least two air springs are used, which are arranged symmetrically to the guide means provided between them.
Die erfindungsgemäß für die Spannvorrichtung verwendeten Luftfedern ermöglichen die erforderliche Verstellung der regelmäßig parallel zu den anderen Rollen angeordneten Spannrolle mit einem geringen Platzbedarf in der Höhe, also in Verstellrichtung, in der die Parallelität erhalten bleibt. Darüber hinaus ermöglichen die Luftfedern aufgrund der Flexibilität der Federbälge unproblematisch die Verschwenkung der Spannrolle aus der Parallelität zu den anderen Rollen heraus, wobei vorzugsweise die Führungseinrichtung die Schwenkachse bildet. Sind die Luftfedern unmittelbar neben der Führungseinrichtung angeordnet, können Sie aufgrund ihrer Flexibilität die für die benötigten Schwenkwinkel von wenigen Winkelgraden erforderlichen Verformungen unproblematisch mittels der Federbälge mitmachen. Besondere Konstruktionen zur Ermöglichung der Verschwenkbewegung können daher entfallen.The air springs used according to the invention for the tensioning device allow the required adjustment of the regularly arranged parallel to the other rollers tensioner with a small footprint in height, so in the adjustment, in which the parallelism is preserved. In addition, due to the flexibility of the spring bellows, the pneumatic springs make it possible to easily pivot the tensioning roller out of parallelism with the other rollers, with the guide device preferably forming the pivoting axis. If the air springs are arranged directly next to the guide device, you can easily join the necessary for the required pivoting angle of a few degrees deformations due to their flexibility by means of bellows. Special constructions to enable the pivoting movement can therefore be omitted.
In einer besonders bevorzugten Ausführungsform weisen die Luftfedern einen auf einem Kern abrollenden Rollbalg auf. Derartige Luftfedern sind gegenüber Luftfedern mit Faltenbälgen weniger verschleißanfällig und ermöglichen die ggf. benötigte Verformung bei dennoch hoher Stabilität der Luftfeder.In a particularly preferred embodiment, the air springs on a rolling on a core rolling bellows. Such air springs are less prone to wear compared to air springs with bellows and allow the possibly required deformation while still high stability of the air spring.
Sofern die erfindungsgemäße Bandschleifmaschine ferner mit einer Führung für ein Andruckband, insbesondere ein Drucklamellenband, versehen ist, kann die Spannrolle des Andruckbands in der gleichen Weise mit einer Spannvorrichtung aus wenigstens einer Luftfeder und einer Führungseinrichtung versehen sein.If the belt grinding machine according to the invention is further provided with a guide for a pressure belt, in particular a pressure disk belt, the tension roller of the pressure belt can be provided in the same way with a tensioning device of at least one air spring and a guide device.
Die parallele Anordnung der Rollen für das umlaufende Schleifband ist üblich, aber nicht zwingend, da es auch möglich ist, den Geradelauf des Schleifbandes mit zwei spiegelsymmetrisch zueinander verschwenkten Rollen zu realisieren.The parallel arrangement of the rollers for the rotating abrasive belt is common, but not mandatory, since it is also possible to realize the Geradelauf the abrasive belt with two mirror-symmetrically pivoted roles.

Am oberen Ende der Maschine ist eine weitere Rolle 6 als Spannrolle gelagert. Die Spannrolle 6 bildet mit den beiden, zur Spannrolle parallel ausgerichteten Antriebsrollen 2 ein gleichschenkliges Dreieck mit gegenüber der Basis, also dem Abstand zwischen den beiden Antriebsrollen 2, wesentlichen größeren Katheten. Die Spannrolle 6 ist mit einer Spannvorrichtung 7 nach oben verschiebbar. Hierzu ist die Spannrolle 6 mit seitlichen Achsansätzen 8 in seitlichen Laschen 9 gelagert, die auf einer sich über die Länge der Spannrolle 6 erstreckenden Trägerplatte 10 befestigt sind. Die Trägerplatte 10 wird von der Spannvorrichtung 7 in ihrer Höhe eingestellt.At the upper end of the machine, another roller 6 is mounted as a tension roller. The tension roller 6 forms with the two, parallel to the tension roller drive rollers 2 an isosceles triangle with respect to the base, so the distance between the two drive rollers 2, substantially larger catheters. The tension roller 6 is displaceable upwards with a
Die Spannvorrichtung 7 weist in ihrem wesentlichen Aufbau zwei Luftfedern 11 auf, die bezüglich der Längsrichtung der Spannrolle 6 beiderseits einer Führungseinrichtung 12 angeordnet sind. Die Führungseinrichtung 12 ist in der Mitte der Spannrolle 6 mit der Tragplatte 10 verbunden.The
Unterhalb der Spannvorrichtung 7 ist eine weitere entsprechend gelagerte Spannrolle 13 erkennbar, die mit einer entsprechenden Spannvorrichtung 14 ebenfalls in der Höhe verstellbar ist und zur Führung eines (nicht dargestellten) Andruckbandes in Form eines Lamellen-Druckbandes vorgesehen ist. Das Andruckband wird ebenfalls über die Antriebsrollen 2 so geführt, dass es zwischen den Rollen 2 und dem Schleifband liegt. Die Spannung des Andruckbandes wird durch die auf die Spannrolle 13 wirkende Spannvorrichtung 14 bewirkt.Below the
Der Aufbau der in gleicher Weise ausgebildeten Spannvorrichtungen 7, 14 ergibt sich näher aus den
Die Spannvorrichtungen 7, 14 werden mittels einer Konsole 15 auf einem Maschinenträger montiert und weisen eine Grundplatte 16 auf, auf der die Luftfedern 11 und ein Führungsblock 17 der Führungseinrichtung 7 montiert sind. Der Führungsblock 17 bildet eine runde Führungsbuchse für einen entsprechenden runden Führungsbolzen 18, der an einer oberen Platte 19 befestigt ist. Auf der Oberseite der Platte 19 sind Befestigungsstücke 20 angebracht, mit denen die Verbindung zu der Tragplatte 10 der Spannrolle 6 hergestellt wird.The
Der Führungsblock 17 weist Gewindelöcher 28 auf, sodass er mit in die Gewindelöcher 28 eingeschraubten Schrauben an der Platte 16 befestigbar ist. Die Befestigung des Führungsbolzen 18 an der Platte 19 erfolgt mittels eines U-förmigen Lagerstücks 26 und eines Verriegelungsbolzens 27, der eine bezüglich der Hochachse drehfeste und bezüglich seiner horizontalen Längsachse schwenkbare Verbindung mit dem Führungsbolzen 18 herstellt. In den Führungsbolzen 18 ist von seinem freien Ende her stirnseitig eine Schraube 25 eingeschraubt, deren Kopf als Anschlag für die Bewegung des Führungsbolzens 18 dient und verhindert, dass der Führungsbolzen 18 aus dem Führungsblock 17 herausgehoben wird.The
Es ist erkennbar, dass die Luftfedern 11 der Spannvorrichtung 7, 14 einen großen Verstellweg ermöglichen, selbst jedoch einen geringen Platzbedarf in der Höhe haben. Somit ist es ohne weiteres möglich, selbst bei der Ausbildung der Bandschleifmaschine mit einer Spannrolle 13 für ein Drucklamellenband eine Maximalhöhe der Maschine nicht zu überschreiten, sodass die Maschine im montierten Zustand im normalen Straßenverkehr transportierbar ist.It can be seen that the air springs 11 of the
Als Spannrolle 6 kann jede der die Führung des Schleifbandes bewirkenden Rollen 2, 6 fungieren, obwohl die hier als Spannrolle bezeichnete obere Rolle 6 bevorzugt als Spannrolle eingesetzt wird. Die wenigstens eine angetriebene Rolle (Antriebsrolle 2) kann jede der 3 Rollen sein, also auch die Spannrolle 6, die somit gleichzeitig als Antriebsrolle 2 fungieren könnte. Bevorzugt ist jedoch die in der Zeichnung dargestellte Ausführungsform.As a tension roller 6, each of the leadership of the abrasive belt causing rollers 2, 6 act, although the designated here as a tension roller upper roller 6 is preferably used as a tension roller. The at least one driven roller (drive roller 2) may be any of the 3 rollers, including the tension roller 6, which could thus simultaneously act as a drive roller 2. However, preferred is the embodiment shown in the drawing.
