Description

Die Erfindung betrifft ein Schleifwerkzeug mit auf einem Schleifwerkzeugträger angeordneten Schleiftellern, wobei auf dem Schleifwerkzeugträger und zwischen den Schleiftellern Messer zum Spanabheben angeordnet sind, die zudem den gleichen Wirkbereich wie die Schleifteller haben.The invention relates to a grinding tool with grinding plates arranged on a grinding tool carrier, being arranged on the grinding tool carrier and between the grinding plates knife for chip removal, which also have the same effective range as the grinding plates.

Es ist bekannt, Holzböden mit Bandschleifmaschinen oder Maschinen mit rotierenden Schleifscheiben oder auch Schleifwerkzeugträgern zu bearbeiten, um die Oberflächen zu reinigen, zu glätten oder um ein bestimmtes Maß abzutragen. Es ist auch bekannt, Holzböden oder größere Holzflächen im allgemeinen maschinell abzuhobeln, um sie einzuebnen, auszurichten oder abzutragen. Ein Nachteil von Schleifmaschinen ist es, daß das Schleifmittel von eingelassenen oder stark benutzten Holzböden Schmutz-, Lack- und Ölreste im Holz im Reparaturfall verklebt wird. Es treten weiters große Unebenheiten bei abgenutzten Böden auf, die nur mühsam heruntergeschliffen werden können. Es sind auch Maschinen bekannt, die abwechselnd mit Schleifmitteln oder Schneidköpfen bestückt werden können. Nachteil dieser Lösungen ist, daß die Schneidköpfe nur auf die Bearbeitung von Estrichen beschränkt sind, obwohl die Maschinen mit Schleifmitteln bestückt zur Bearbeitung von Holzböden vorgesehen sind.It is known to machine wood floors with belt sanders or machines with rotating grinding wheels or grinding tool carriers to clean the surfaces, smooth or to remove a certain amount. It is also known to machine-plan wood floors or larger wood surfaces generally to level, level or remove them. A disadvantage of grinding machines is that the abrasive is stuck by recessed or heavily used wood floors dirt, paint and oil residues in the wood in case of repair. There are also large bumps on worn floors, which can be ground down only with difficulty. There are also known machines that can be alternately equipped with abrasives or cutting heads. Disadvantage of these solutions is that the cutting heads are limited only to the treatment of screeds, although the machines are equipped with abrasives for the processing of wooden floors.

Die US 4 295 274 lehrt eine Bodenbearbeitungsmaschine, bei welcher in einer Ausführungsform auf einer rotierenden Scheibe sowohl Hobelmesser als auch Schleifbürsten von im wesentlichen trapezförmiger Fläche angeordnet sind, um den Boden gleichzeitig zu hobeln und zu schleifen. Nachteilig bei dieser Lehre ist, daß die Maschine nur auf den einzigen Betrieb des ungefähr gleichartigen Hobelns und Schleifens ausgelegt ist, da die Bürsten eine feststehende Länge aufweisen und nicht ohne aufwendige Eingriffe ausgetauscht werden können. Mit der Maschine gelingt es nicht, die Hobel- und die Schleifwirkung fein aufeinander abzustimmen oder eine der beiden Wirkungen herauszunehmen.The US 4,295,274 teaches a tillage machine in which, in one embodiment, both planer knives and abrasive brushes of substantially trapezoidal surface are disposed on a rotating disk to simultaneously plan and grind the floor. A disadvantage of this teaching is that the machine is designed only for the single operation of approximately similar planing and grinding, since the brushes have a fixed length and not without complicated interventions can be exchanged. With the machine, it is not possible to fine-tune the planing and grinding effects or to remove one of the two effects.

Die WO 87/03241 A1 offenbart ein kombiniertes Werkzeug zum Planen und Fräsen einer Holzoberfläche. Dabei ist der Zentralbereich einer rotierenden flachen Scheibe mit einer Schleifpapieroberfläche versehen, und am Außenumfang des Bereiches mit Schleifpapier sind drei Schneiden angeordnet. Wenn dieses Werkzeug rotiert, wird folglich eine ebene Holzoberfläche mit Sandpapier geschliffen und mit den Schneiden plangefräst. Nachteilig ist hier, daß eine Holzoberfläche bei zwar rotierendem Schleifwerkzeug geschliffen und gefräst wird, daß jedoch für ein gutes Ergebnis die Maschine insgesamt beständig und auf sorgfältige Weise bewegt werden muß. Andernfalls wird bei ruhendem Werkzeug nur ein zentraler Bereich geschliffen und ein zweiter Bereich separat gefräst.The WO 87/03241 A1 discloses a combined tool for planning and milling a wood surface. In this case, the central portion of a rotating flat disc is provided with a sandpaper surface, and on the outer periphery of the area with sandpaper three blades are arranged. As this tool rotates, a flat wooden surface is sandpapered and planed with the blades. The disadvantage here is that a wood surface is ground and milled while rotating grinding tool, however, that for a good result, the machine must be constantly and consistently moved in a careful manner. Otherwise, only one central area is ground and a second area milled separately when the tool is at rest.

Die US 2005/0054279 A1 lehrt eine Bodenbearbeitungsscheibe für rotierende Bodenbearbeitungsmaschinen. Bei diesem Gerät werden auf eine große rotierende Scheibe drei abermals rotierende Scheiben montiert, die austauschbar entweder fräsende oder schleifende Oberflächen besitzen. Nachteilig hierbei ist, daß diese Maschine nicht dazu vorgesehen ist, in einem Arbeitsgang gleichzeitig zu fräsen und zu schleifen.The US 2005/0054279 A1 teaches a soil tillage disc for rotary tillage machines. In this device, three again rotating discs are mounted on a large rotating disc, which interchangeably have either milling or grinding surfaces. The disadvantage here is that this machine is not intended to simultaneously mill and grind in one operation.

Gleiches gilt für die US 5 885 139 A , bei welcher eine Seite eines scheibenförmigen Schleifwerkzeugträgers Schneiden und die andere Seite Schleifteller aufweist. Bei einer Maschine dieser Lehre kann man dann wählen, ob man entweder schleifen oder separat davon fräsen möchte und montiert dementsprechend den Schleifwerkzeugträger an dem Bodenbearbeitungswerkzeug mit der gewünschten Seite nach unten.The same applies to the US Pat. No. 5,885,139 in which one side of a disk-shaped grinding tool carrier has cutting edges and the other side has grinding plates. In a machine of this teaching you can then choose whether you either grind or would like to mill separately and accordingly mounted the grinding tool carrier on the tillage tool with the desired side down.

Die DE 20 2006 014 965 U1 und die DE 201 20 137 U1 offenbaren Bodenbearbeitungsmaschinen mit rotierenden Scheiben, auf denen entweder Schleifbeschläge oder Schneiden montiert sind.The DE 20 2006 014 965 U1 and the DE 201 20 137 U1 disclose tillage machines with rotating discs on which either grinding fittings or cutting edges are mounted.

Die WO 2008/153486 A1 und die JP 3 015070 U lehren Bodenbearbeitungsgeräte mit rotierenden Scheiben, auf denen neben Holzbearbeitungselementen auch Bürsten zum Entfernen von Schleifstaub montiert sind.The WO 2008/153486 A1 and the JP 3 015070 U teach tillage implements with rotating discs on which woodworking elements and brushes for removing sanding dust are mounted.

Die US 5 054 245 offenbart ein Schleifwerkzeug mit den Merkmalen des Oberbegriffs des Anspruchs 1.The US 5 054 245 discloses a grinding tool having the features of the preamble of claim 1.

Die Erfindung zielt darauf ab, ein Schleifwerkzeug für ein Bodenschleifgerät zu schaffen, das es ermöglicht, Böden und insbesondere Holzböden gleichzeitig zu hobeln und zu schleifen, sowie die Eindringtiefe der Hobelschneiden anpassen zu können. Ein weiteres Ziel besteht darin, eine einfache Anpassung der Eindringtiefe zu ermöglichen und bis zu einer vollkommenen Aufhebung der Eindringtiefe einstellbar zu lassen.The invention aims to provide a grinding tool for a floor grinder, which makes it possible to plan and grind floors and wooden floors in particular at the same time, as well as to be able to adapt the penetration depth of the planing cutters. Another objective is to allow a simple adjustment of the penetration depth and to leave it adjustable until complete cancellation of the penetration depth.

Das erfindungsgemäße Schleifwerkzeug erreicht dies durch die Merkmale des Anspruchs 1.The grinding tool according to the invention achieves this by the features of claim 1.

Eine bevorzugte Ausführungsform des Schleifwerkzeuges zeichnet sich dadurch aus, daß die Messer Hartmetallwendeplatten sind.A preferred embodiment of the grinding tool is characterized in that the blades are carbide inserts.

Eine weitere bevorzugte Ausführungsform des Schleifwerkzeuges zeichnet sich dadurch aus, daß das Mittel zum lösbaren Befestigen der Schleifbeläge auf den Schleiftellern eine von zwei Klettverschlußflächen ist.A further preferred embodiment of the grinding tool is characterized in that the means for releasably securing the abrasive coatings on the sanding pads is one of two Velcro closure surfaces.

Eine weitere bevorzugte Ausführungsform des Schleifwerkzeuges zeichnet sich dadurch aus, daß mindestens ein Schleifpapier auf der dem Schleifmittel abgewandten Seite mit einem Filz fest verbunden und dieser wiederum mit einer Klettverschlußfläche fest verbunden ist.Another preferred embodiment of the grinding tool is characterized in that at least one abrasive paper on the side facing away from the abrasive with a felt firmly connected and this in turn is firmly connected to a Velcro closure surface.

Die Erfindung wird nachstehend anhand eines in den Zeichnungen dargestellten Ausführungsbeispieles näher erläutert. Es zeigen: Fig. 1 eine Draufsicht auf die Unterseite eines Schleifwerkzeugträgers, Fig. 2 einen Ausschnitt aus einer Seitenansicht auf den Schleifwerkzeugträger und Fig. 3 einen Schleifbelag.The invention will be explained in more detail with reference to an embodiment shown in the drawings. Show it: Fig. 1 a top view of the underside of a grinding tool carrier, Fig. 2 a section of a side view on the grinding tool carrier and Fig. 3 an abrasive coating.

Gemäß Fig. 1 sind mit einer Schleifscheibe bzw. einem Schleifwerkzeugträger 1, der als massive Aluminiumplatte ausgeführt sein kann, mehrere Schleifteller 2 derart verbunden, daß sie frei rotieren können. Der Schleifwerkzeugträger 1 wird mit einem Antriebsmittel in Richtung D zur Rotation gebracht. Auf den dem Boden zugewandten Seiten der Schleifteller 2 ist, wie in Fig. 2 gezeigt, ein Schleifbelag 5 angebracht. Der Schleifbelag 5 besteht aus Schleifpapier. In Fig. 2 weist die Seite, die der zu bearbeitenden Oberfläche zugewandt ist, nach oben. Der Schleifbelag 5 und der Schleifteller 2 können mittels Klettverschlüssen lösbar miteinander verbunden werden. Zwischen den Schleiftellern 2 sind, wie in Fig. 1 weiters gezeigt, mit Messern 4 bestückte Schneidköpfe 3 angeordnet und mit dem Schleifwerkzeugträger 1 fest verbunden. Aus Fig. 2 ist ersichtlich, daß die Unterkante der Messer 4 auf ähnlicher oder gleicher Höhe wie die Schleifebene des Schleifbelages 5 verläuft. Dadurch ist gewährleistet, daß die zu bearbeitende Oberfläche gleichzeitig gehobelt und geschliffen wird. Insbesondere bei verschmutzten oder öligen Oberflächen wird mit dieser Anordnung der Effekt erzielt, daß die Messer 4 die entsprechenden Substanzen abheben und an einem verklebenden Eindringen in den Schleifbelag 5 hindern.According to Fig. 1 are connected with a grinding wheel or a grinding tool carrier 1, which can be designed as a solid aluminum plate, a plurality of sanding plates 2 such that they can rotate freely. The grinding tool carrier 1 is brought to a drive means in the direction D for rotation. On the bottom facing sides of the sanding pad 2, as in Fig. 2 shown, an abrasive pad 5 attached. The abrasive pad 5 is made of sandpaper. In Fig. 2 points up the side facing the surface to be machined. The abrasive pad 5 and the sanding pad 2 can be releasably connected to each other by means of Velcro. Between the sanding plates 2 are, as in Fig. 1 further shown, fitted with knives 4 cutting heads 3 arranged and fixedly connected to the grinding tool carrier 1. Out Fig. 2 It can be seen that the lower edge of the knife 4 runs at a similar or the same height as the grinding plane of the abrasive coating 5. This ensures that the surface to be machined is simultaneously planed and ground. In particular, in the case of soiled or oily surfaces, this arrangement achieves the effect that the knives 4 lift off the corresponding substances and prevent them from adhering to the abrasive coating 5.

Fig. 2 zeigt zudem die Ausführungsform der Hobelmittel. Der Schneidkopf 3 ist als Block ausgeführt, in den scheibenförmige Messer 4 (z.B. Hartmetallwendeplatten) eingesetzt und festgeschraubt werden. Fig. 2 also shows the embodiment of the planing means. The cutting head 3 is designed as a block, used in the disc-shaped blade 4 (eg carbide inserts) and screwed tight.

Je nach Bodenbeschaffenheit und Arbeitsgang kann es vorteilhaft sein, daß die Messer 4 nicht in gleicher Ebene wie die Schleifbeläge 5 liegen. Eine Höhendifferenz, die beispielsweise im Bereich einiger Zehntel Millimeter liegt, läßt sich dadurch herstellen, daß Schleifbeläge 5 von unterschiedlicher Stärke auf die Schleifteller 2 aufgebracht werden. Die Stärke hängt von der Korngröße des Schleifpapiers ab. Fig. 3 zeigt eine weitere stärkenverändernde Anordnung für den Schleifbelag 5. Auch hier weist die Seite, die der zu bearbeitenden Oberfläche zugewandt ist, nach oben. Das Schleifmittel 6 ist mit einem Filz 8 zum Beispiel durch eine Klebeschicht 7 fest verbunden. Der Filz 8 ist wiederum mit einer Hälfte eines Klettverschlusses 10 zum Beispiel durch eine Klebeschicht 9 fest verbunden. Durch die Stärke des Filzes 8 ist die Stärke des Schleifbelages 5 und damit die Höhe der Schleifebene steuerbar.Depending on the nature of the soil and the operation, it may be advantageous that the blades 4 are not in the same plane as the abrasive pads 5. A height difference, which is for example in the range of a few tenths of a millimeter, leaves be prepared by the fact that abrasive coatings 5 are applied to the sanding plates 2 of different thickness. The thickness depends on the grain size of the abrasive paper. Fig. 3 shows a further strength-changing arrangement for the abrasive coating 5. Again, the side facing the surface to be machined, upward. The abrasive 6 is fixedly connected to a felt 8, for example by an adhesive layer 7. The felt 8 is in turn firmly connected to one half of a hook-and-loop fastener 10, for example by an adhesive layer 9. Due to the thickness of the felt 8, the thickness of the abrasive pad 5 and thus the height of the loop plane is controllable.

Der Wechsel von einem einfachen Schleifbelag 5 zu einem in Fig. 3 gezeigten Schleifbelag 5 bewirkt die gewünschte Änderung der Höhendifferenz zwischen Schleifbelag 5 und Hobelhöhe der Messer 4. Durch diese Maßnahme können die Messer 4 auch gänzlich von der zu bearbeitenden Oberfläche abgehoben werden, so daß das Bodenschleifgerät insgesamt nur noch als reines Schleifgerät arbeitet. Dies kann insbesondere beim Feinschliff erwünscht sein.The change from a simple abrasive 5 to a in Fig. 3 As a result of this measure, the knives 4 can also be lifted completely off the surface to be processed, so that the floor grinder works altogether only as a pure grinding device. This may be desirable in particular during fine grinding.

Ein weiterer Vorteil dieser Lösung liegt darin, daß für das Schleifpapier durch den Filz 8 eine weiche und anpassungsfähige Auflage geschaffen ist.Another advantage of this solution is that a soft and conformable support is provided for the sandpaper by the felt 8.

Es versteht sich, daß die geschilderten Ausführungsbeispiele im Rahmen des Erfindungsgedankens, der durch die Ansprüche 1-6 definiert wird verschiedentlich abwandelbar sind, z.B. hinsichtlich Schleifpapierart, Schleifkorntyp, Klebemittel, Verbindungsmittel von Schleifbelag, Filz oder Schleifteller, Schleiftelleranzahl oder Messertyp.It is understood that the described embodiments are variously modifiable within the scope of the inventive concept defined by the claims 1-6, e.g. with regard to type of abrasive paper, type of abrasive grain, adhesive, abrasive coating agent, felt or sanding pad, sanding pad number or knife type.
