Description

Die Erfindung betrifft eine Schleifwalze für die Steinbearbeitung.The invention relates to a grinding roller for stone processing.

Aus der DE 40 32 889 C1 ist eine Schleifwalze mit einem zylindrischen Walzenkörper und einem Schleifmittel bekannt. Das Schleifmittel besteht aus einem auf der Arbeitsseite aufgeschlitzten und damit Lamellen bildenden Band. Die Lamellen spreizen sich bei der Rotation der Schleifwalze ab und bearbeiten das Werkstück. Das bandförmige Schleifmittel ist über eine sogenannte Klettverbindung mit dem Walzenkörper verbunden. Ein Ende des Schleifmittels sitzt in einem radialen Schlitz im Walzenkörper. Für die Steinbearbeitung ist diese Schleifwalze nur wenig geeignet.DE 40 32 889 C1 describes a grinding roller with a cylindrical one Roll body and an abrasive known. The abrasive consists of one on the working side slit and thus forming slats. The Lamellae spread out as the grinding roller rotates and work on it Workpiece. The band-shaped abrasive is a so-called Velcro connection connected to the roller body. One end of the abrasive sits in one radial slot in the roller body. This grinding roller is for stone processing not very suitable.

Die DE GM 19 00 505 zeigt eine Schleifwalze für eine Fußbodenschleifmaschine. Hierbei wird das Schleifmittel innerhalb des Walzenkörpers von zwei von Druckfedern vorgespannten Spannbolzen gehalten. Der Druck der Federn läßt sich durch Schrauben regulieren.DE GM 19 00 505 shows a grinding roller for a floor grinding machine. Here, the abrasive is removed from two of the inside of the roller body Prestressed tension bolts held by compression springs. The pressure of the springs can be regulate by screws.

Der Erfindung liegt die Aufgabe zugrunde, eine für die Steinbearbeitung einsetzbare Schleifwalze so zu verbessern, daß nur noch ein Mittel zum Halten und gleichzeitig zum Verbinden des Schleifmittels mit der Schleifwalze und damit mit dem Antrieb notwendig ist.The invention has for its object to be used for stone processing To improve grinding roller so that only one means to hold and at the same time for connecting the abrasive to the grinding roller and thus to the drive necessary is.

Die erfindungsgemäße Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Verteilhafte Weiterbildungen der Erfindung sind den Merkmalen der Unteransprüche zu entnehmen.The object of the invention is achieved by the features of claim 1. Distributive developments of the invention are the features of the subclaims refer to.

Die Erfindung geht davon aus, daß die zur Steinbearbeitung eingesetzten Schleifmittel aus einer Trägerschicht, beispielsweise aus Kunstleder bestehen, auf die ein Schleifmittelbelag, beispielsweise ein Origamisheet mit Diamantsegmenten, aufgebracht ist. Ein dementsprechendes oder anderes für die Steinbearbeitung eingesetztes Schleifmittel ist gegenüber sonstigen Schleifmitteln für Holz oder dergleichen wesentlich schwerer. The invention assumes that those used for stone processing Abrasives consist of a backing layer, for example made of synthetic leather, on the an abrasive coating, for example an origami sheet with diamond segments, is applied. A corresponding one or another for stone processing The abrasive used is compared to other abrasives for wood or the like much more difficult.

Dieser Gewichtsunterschied bei Umdrehungsgeschwindigkeiten von zum Beispiel 900 bis 1000 U/min bewirkt eine sehr große Zentrifugalkraft, der das Schleifband ausgesetzt ist. Aufgrund der über die gesamte Oberfläche sich erstreckenden Klettverbindung haftet das Schleifmittel am Umfang des Walzenkörpers. Die absolut sichere Verbindung mit dem Walzenkörper geht das Schleifband jedoch über einen radialen Schlitz ein, der mit einer zusätzlichen Spannvorrichtung ausgestattet ist.This weight difference at speeds of rotation, for example 900 to 1000 rpm causes a very large centrifugal force that the sanding belt is exposed. Due to the fact that it extends over the entire surface The abrasive adheres to the circumference of the roller body with Velcro. The absolutely however, the sanding belt has a secure connection to the roller body radial slot, which is equipped with an additional clamping device.

Die Spannvorrichtung besteht vorteilhafterweise aus dem Walzenkörper selbst, der mindestens an einer, vorzugsweise an beiden Enden, eine konische Ringnut aufweist, in die ein- oder beidseitig Spannringe eingreifen. Je nachdem, wie weit der/die Spannring/e in den Konus oder die Konen des Walzenkörpers eindringen, schließt sich der Schlitz, in dem ein Ende des Schleifbandes sitzt. Dabei übernimmt/übernehmen der oder die Spannring/e gleichzeitig eine Zentrierfunktion, die notwendig ist, um einen ringförmigen Hohlraum zwischen der Welle und der Schleifwalze zu bilden. Der Hohlraum wird als Schmier- bzw. Kühlmittelraum genützt. Von ihm aus gehen Bohrungen zur Oberfläche der Schleifwalze und zur Schmiermittelzufuhrleitung in der Welle.The tensioning device advantageously consists of the roller body itself, the has a conical annular groove at least at one, preferably at both ends, engage in the clamping rings on one or both sides. Depending on how far the / the Clamping ring / s penetrate into the cone or the cones of the roller body, closes the slot in which one end of the sanding belt sits. there the clamping ring (s) simultaneously perform a centering function, which is necessary to create an annular cavity between the shaft and the Forming grinding roller. The cavity is called a lubricant or coolant space used. From it, holes go to the surface of the grinding roller and to Lubricant supply line in the shaft.

In einer weiteren vorteilhaften Weiterbildung der Erfindung weist der Walzenkörper zwei Schlitze auf. Mit dieser Ausführung kann entweder der Schleifwalzenumfang oder die Walzenlänge verdoppelt werden, wobei Schleifbänder, auch Sheets genannt, mit gleichen Längen zum Einsatz gelangen.In a further advantageous development of the invention, the roller body has two slots. With this version, either the grinding roller circumference or the roll length can be doubled, whereby grinding belts, also called sheets, with the same lengths.

In einer weiteren vorteilhaften Ausführung weist die Welle eine Distanzbüchse auf. Damit läßt sich die wirksame Schleifoberfläche bei gleicher Breite der zu verwendenden Schleifbänder in kurzer Zeit auf die Hälfte reduzieren, indem nur ein Schleifband in horizontaler Lage zum Einsatz kommt.In a further advantageous embodiment, the shaft has a spacer sleeve. This allows the effective grinding surface with the same width Use abrasive belts in half in a short time by just one Abrasive belt in a horizontal position is used.

In einer weiteren vorteilhaften Ausführung, die insbesondere den Einsatz der Schleifwalze mit zwei Schlitzen betrifft, können die beiden Walzenkörperteile durch zusätzlich zu den Spannringen vorgesehene Spannstücke fixiert werden. Dazu sind die Spannstücke segmentartig geformt und mit Laschen an ihren Enden versehen. Zur Feineinstellung der Spannkraft sind vorzugsweise vier Spannstücke vorgesehen, die mit den Teilen des Walzenkörpers verschraubt und über Spannschrauben gegeneinander verspannt sind.In a further advantageous embodiment, which in particular the use of Regarding grinding roller with two slots, the two roller body parts can pass through In addition to the clamping rings provided clamping pieces can be fixed. To do this the clamping pieces shaped like a segment and provided with tabs at their ends. For the fine adjustment of the clamping force, four clamping pieces are preferably provided, which are screwed to the parts of the roller body and via clamping screws are braced against each other.

Zieht man die Mutter 38 an das Spannstück 36 heran, so dringt die ringförmige Feder 40 des Spannstücks 36 in die konische Ringnut 42 und die Feder 44 in die konische Ringnut 46 des Walzenkörpers 32 ein. Damit zentriert man den Walzenkörper 32 und bildet gleichzeitig den ringzylindrischen Hohlraum 48. Ebenso bewirken die Spannringe 34,36, daß der Schlitz 50 in dem ein Ende des Schleifbands 52 eingesetzt ist, die Weite des Schlitzes verringert und damit das Schleifbandende festspannt. Das Schleifband 52 besteht aus einer Kunstlederschicht 54 auf der Diamantschleifmittelsegmente 56 aufgebracht sind. Über die Welle 30 die mit einer axialverlaufenden Bohrung 58 versehen ist gelangt Kühl- bzw Schmiermittel über weitere radiale Bohrungen 60,62 bis an die Schleifbandoberfläche. The grinding roller structure described in FIG. 2 shows that shown in FIG. 1 Grinding roller 24. The shaft 30 with the drive stands by means of the screw flange 28 22 in connection. The shaft 30 sits on the left and right of the roller body 32 the tension rings 34,36. The clamping rings 34, 36 are movably seated on the shaft 30 and can thus by turning the nut 38, which has a thread with the shaft is connected to the roller body 32 to be clamped. If you pull the mother 38 to the clamping piece 36, the annular spring 40 of the clamping piece 36 penetrates in the conical annular groove 42 and the spring 44 in the conical annular groove 46 of the Roller body 32 a. This is used to center and form the roller body 32 at the same time the ring-cylindrical cavity 48. The clamping rings also effect 34,36 that the slot 50 is inserted in one end of the grinding belt 52, the The width of the slot is reduced and the end of the sanding belt is tightened. The Sanding belt 52 consists of a synthetic leather layer 54 on the Diamond abrasive segments 56 are applied. Via the shaft 30 with a axially extending bore 58 is provided coolant or lubricant further radial bores 60, 62 up to the surface of the sanding belt.

    An die Unterseite der Kunstlederschicht 54 wird ein Fließ 64 aufgeklebt, das mit den Widerhaken des Kletteils 66 am Walzenkörper einen festen aber lösbaren Kontakt eingeht.At the bottom of the synthetic leather layer 54, a flow 64 is glued, which with the Barbs of Velcro 66 on the roller body make a firm but detachable contact comes in.

    Die in Fig. 3 dargestellte Schleifwalze 24 weist einen Schlitz 50 auf der von der äußeren Oberfläche der Schleifwalze 24 bis zum Hohlraum 48 reicht. Der Walzenkörper 32 ist demnach einseitig durchgehend geschlitzt. In diesem Beispiel ist das Schleifband 54 im Bereich des Schleifmittels und an dessen Ende über eine Klettverbindung mit der Walzenoberfläche und im Schlitz 50 mittels einer Klettverbindung lösbar befestigt.The grinding roller 24 shown in Fig. 3 has a slot 50 on the of outer surface of the grinding roller 24 extends to the cavity 48.
