Description

Vorrichtung zum Reinigen von Schleifbändern Die Erfindung betrifft eine Vorrichtung zum Reinigen der Schleifbänder bei Bandschleifmaschinen mit im Bereich des Absaugekastens angeordneten, mit dem Schleifband ständig im Eingriff stehenden Reinigungsrollen. Bisher werden, als Reinigungsrollen rotierende Bürsten verwendet, deren Borsten, aus Haar oder Stahldraht bestehen. Haarborsten haben den Nachteil, daß sie sich sehr schnell abnutzen. Borsten aus Stahldraht verletzen bei der Berührung mit der Bandoberfläche den Schleifbelag.Apparatus for cleaning abrasive belts The invention relates to a device for cleaning the sanding belts in belt sanders with im Area of the suction box arranged, constantly in engagement with the sanding belt standing cleaning rollers. So far, rotating brushes are used as cleaning rollers used, the bristles of which are made of hair or steel wire. Hair bristles have that Disadvantage that they wear out very quickly. Steel wire bristles injure the contact with the belt surface the abrasive layer.

Um die Nachteile der bekannten Reinigungsrollen zu vermeiden, wird erfindungsgemäß eine Reinigungsrolle vorgeschlagen, deren Mantel aus einem elastischen, hitzebeständigen und abriebfesten Material besteht, das auf der Oberfläche Poren hat. Bei Berührung der Manteloberfläche mit der Bandoberfläche wird der in die Lücken zwischen den Schleifkörnern eingedrungene Schleifstaub durch die Saugwirkung der Poren abgezogen, ohne den Belag selbst zu verletzen, wodurch die Lebensdauer der Bänder wesentlich erhöht wird. Von der Reinigungsrolle wird der Staub teils durch Zentrifugalwirkung, teils durch eine mitrotierende Borstenwalze, die mit der Reinigungswalze zusammen oder getrennt verschwenkbar ist, entfernt. Um zu verhindern, daß sich die Reinigungsrolle infolge der steten Berührung mit dein Schleifband allzu stark erwärmt, ist eine Kühleinrichtung in Form einer an sich bekannten, die Reinigungsrolle überdeckende Kühlluft zuführenden Düse vorgesehen. Eine weitere Kühlung in Verbindung mit einer gleichzeitigen Reinigung der Reinigungsrolle, kann dadurch erfolgen, daß durch die, hohl ausgebildete, mit radialen Öffnungen versehene Welle der Borstenwalze Luft geführt wird, die aus den Öffnungen der Welle während des Umlaufes ausströmt.In order to avoid the disadvantages of the known cleaning rollers proposed according to the invention a cleaning roller, the jacket of which is made of an elastic, Heat-resistant and abrasion-resistant material is made up of pores on the surface Has. When the surface of the jacket touches the surface of the belt, it gets into the gaps Sanding dust that has penetrated between the abrasive grains due to the suction effect of the Pores are peeled off without damaging the covering itself, increasing the life of the Ligaments is increased significantly. Some of the dust gets through from the cleaning roller Centrifugal effect, partly through a rotating bristle roller that works with the cleaning roller is pivotable together or separately, removed. To prevent the The cleaning roller is too hot due to the constant contact with your sanding belt, is a cooling device in the form of a known per se, covering the cleaning roller Cooling air supply nozzle provided. Another cooling in conjunction with a simultaneous cleaning of the cleaning roller can be done by the, hollow shaft of the bristle roller air provided with radial openings is performed, which flows out of the openings of the shaft during the revolution.

Zur Unterstützung des Reinigungsvorganges können in an sich bekannter Weise auch auf die Schleifbandoberfläche gerichtete Blas- oder Spritzdüsen angeordnet sein. Es können ferner mehrere Reinigungsrollen und Düsen vorgesehen. werden.To support the cleaning process, known per se Way also directed to the sanding belt surface blowing or spray nozzles arranged be. A plurality of cleaning rollers and nozzles can also be provided. will.

In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen. Vorrichtung schematisch dargestellt.In the drawing is an embodiment of the invention. Device shown schematically.

In das untere erweiterte Ende des Absaugekastens a ragt die Umlenkrolle b des Schleifbandes c hinein. Die Reinigungsrolle d, deren Mantel e aus elastischem, hitzebeständigem und abriebfestem Material besteht, das auf der Oberfläche Poren hat, steht mit dein Band c in ständiger Berührung. Eine mit Borsten besetzte Walze f steht mit der Ralle d im Eingriff und entfernt den in den Poren sitzenden Schleifstaub, der zum Teil auch durch Zentrifugalwirkung abgeschleudert und von dem im Absaugekasten herrschenden Saugzug abgeführt wird. Im Bereich, des Saugekastens ist ferner eine die Breite des Schleifbandes bestreichende Blasdüse g angeordnet. Durch die Düse h, die einen möglichst großen Teil der Oberfläche der Reinigungsrolle d, e erfaßt, wird Kühilluft gegen die Rolle bzw. deren Mantel geführt. Die Reinigungsrolle d und die Borstenwalze f sind in bekannter Weise schwenkbar gelagert. Durch die hohle Welle der Walze f wird Kühlluft geführt, die durch (nicht dargestellte) Öffnungen zwischen den Borsten austritt.The pulley protrudes into the lower extended end of the suction box a b of the sanding belt c into it. The cleaning roller d, whose jacket e is made of elastic, Heat-resistant and abrasion-resistant material that has pores on the surface is in constant contact with your volume c. A roller covered with bristles f is in engagement with claw d and removes the sanding dust sitting in the pores, which is partly thrown off by centrifugal action and from the one in the suction box prevailing induced draft is discharged. In the area of the suction box there is also a the width of the abrasive belt sweeping blow nozzle g arranged. Through the nozzle h, which covers the largest possible part of the surface of the cleaning roller d, e, cooling air is passed against the roll or its jacket. The cleaning roller d and the bristle roller f are pivotably mounted in a known manner. Through the hollow The shaft of the roller f is guided by cooling air through openings (not shown) emerges between the bristles.
