Description

Die vorliegende Erfindung betrifft ein Federelement zu einer Bodenbearbeitungsmaschine gemäß Oberbegriff des Patentanspruchs 1.The present invention relates to a spring element for a tillage machine according to the preamble of patent claim 1.

Vor allem für die Erneuerung und Ausbesserung von Bodenbelägen werden verschiedene Bearbeitungsmaschinen verwendet.Especially for the renovation and repair of floor coverings, various processing machines are used.

Zum einen kennt man für die grobe Bearbeitung von Asphalt, Beton oder andern Hartbelägen Fräsmaschinen. Eine Maschine dieser Art ist in EP0661144B1 beschrieben. Solche Maschinen sind mit Werkzeugen bestückt, wie sie in der US Patentveröffentlichung Nr. US2003/0062760A1 offenbart sind.On the one hand, milling machines are known for the rough machining of asphalt, concrete or other hard surfaces. A machine of this kind is in EP0661144B1 described. Such machines are equipped with tools as described in US Patent Publication no. US2003 / 0062760A1 are disclosed.

Das grobe Eliminieren von Boden-Unebenheiten kann mit Fräsmaschinen auf der Fräsrädchen montiert sind mit hoher Effizienz erreicht werden. Diese Bearbeitung eignet sich vortrefflich für die Vorbereitung von Flächen auf denen ein weiterer Belag aufgetragen wird. Ist jedoch das Resultat einer fein geschliffenen Oberfläche erwünscht, muss ein anderes Werkzeug eingesetzt werden.The rough elimination of soil imperfections can be achieved with milling machines mounted on the milling cutter with high efficiency. This treatment is excellently suited for the preparation of surfaces on which another coating is applied. However, if the result of a finely ground surface is desired, another tool must be used.

Sollen auf einem flachen Plattenboden Schmutz entfernt und/oder sehr kleine Unebenheiten eliminiert werden, nimmt man für feine Prozesse Bodenschleifmaschinen, mit den passenden Schleifwerkzeugen. Eine solche Vorrichtung ist z. B. in WO2006/000542A1 vorgestellt.If you want to remove dirt on a flat slab and / or eliminate very small bumps, you can use bottom grinding machines for fine processes with the right grinding tools. Such a device is z. In WO2006 / 000542A1 presented.

Der Einsatz von Schleifmittel zusammen mit abrasiven Inhalten versehenen Flüssigkeiten, eignet sich sehr gut für die Schmutzentfernung und den Feinschliff. Mit dieser Bearbeitung kann eine ebenmäßig feine Oberfläche erzielt werden. Wenn grobe Unebenheiten entfernt werden müssen, sind die bekannten Werkzeuge für Bodenschleifmaschinen jedoch nicht geeignet, weil sie sich den Unebenheiten nicht genügend anpassen.The use of abrasives together with abrasive liquids provides excellent dirt removal and fine sanding. With this treatment, an evenly fine surface can be achieved. However, when rough bumps have to be removed, the known tools for floor grinding machines are not suitable because they do not sufficiently accommodate the bumps.

Beide Geräte sind für den zugedachten Bereich gut einsetzbar und werden in der Praxis in einer Vielzahl eingesetzt. Wenn es aber um ein universeller einzusetzendes Werkzeug geht, mit dem auf vielen unterschiedlichen Belägen Schmutz entfernt und Unebenheiten ausgeglichen werden sollen, sind die erwähnten Werkzeuge zu speziell. In Einsatzbereichen zwischen grobem Bearbeiten von Flächen und feinstem Entfernen von Schmutz und Schleifen von Oberflächen, gibt es keine passenden Werkzeuge. Insbesondere für die Bearbeitung von Holzoberflächen fehlen die geeigneten Werkzeuge.Both devices are well suited for the intended area and are used in practice in a variety. But when it comes to a universal tool to be used to remove on many different coverings dirt and unevenness should be compensated, the tools mentioned are too special. In applications ranging from rough machining of surfaces to the finest removal of dirt and sanding of surfaces, there are no suitable tools. In particular, for the machining of wood surfaces missing the appropriate tools.

Schleifmaschinen, wie z. B. in CH699037B1 beschrieben, vermeiden das Einschleifen von Spuren in feinen Oberflächen, indem die Schleifwerkzeuge auf einem elastischen Belag (Schaumstoff, Gummi etc.) befestigt sind. Sie passen sich einer ebenmäßigen und feinen Oberfläche wie der eines flachen Plattenbodens gut an. Die flexible Befestigung der Schleifelemente verunmöglicht jedoch eine intensive Bearbeitung des Plattenbodens. Bei zu großem Druck auf die Werkzeuge, welcher notwendig ist um Unebenheiten elastisch reagierend auszugleichen, steigt der Reibungswiderstand auf dem Plattenboden. Dies hat zur Folge, dass die einzelnen Werkzeuge sich im elastischen Belag neigen und unerwünschte Spuren im Plattenboden hinterlassen. Ganz untauglich sind solche Schleifmaschinen und ihre Werkzeuge für das Bearbeiten von Holzböden.Grinding machines, such. In CH699037B1 described, avoid the grinding of traces in fine surfaces by the grinding tools on an elastic covering (foam, rubber, etc.) are attached. They adapt well to an even and fine surface like that of a flat plate floor. However, the flexible attachment of the grinding elements makes it impossible to intensive processing of the plate floor. Too much pressure on the tools, which is necessary to compensate for unevenness elastically reacting increases the frictional resistance on the plate floor. This has the consequence that the individual tools tend in the elastic covering and leave unwanted traces in the bottom of the plate. Completely unfit are such grinders and their tools for working on wooden floors.

Die vorliegende Erfindung stellt sich nunmehr die Aufgabe ein Werkzeug zu einer Bodenbearbeitungs-maschine der eingangs genannten Art derart zu gestalten, dass viele Aufgaben, welche bisher entweder mit großem Aufwand mittels zwei Werkzeugen, oder gar nicht ausgeführt werden konnten, mit ein und demselben Werkzeug besorgt werden können.The present invention now has the task of designing a tool to a tillage machine of the type mentioned in such a way that many tasks that previously either with great effort by means of two tools, or could not be performed, worried with one and the same tool can be.

Diese Aufgabe löst ein Federelement zu einer Bodenbearbeitungsmaschine mit den Merkmalen des Patentanspruches 1. Weitere erfindungsgemäße Merkmale gehen aus den abhängigen Ansprüchen hervor und deren Vorteile sind in der nachfolgenden Beschreibung erläutert.This object is achieved by a spring element to a tillage machine with the features of claim 1. Further features of the invention will become apparent from the dependent claims and the advantages thereof are explained in the following description.

Die Figuren stellen mögliche Ausführungsbeispiele dar, welche in der nachfolgenden Beschreibung erläutert werden.The figures represent possible embodiments, which will be explained in the following description.

In Fig. 1 ist ein Federelement 1 gezeigt, welches auf einer Basis der Bodenbearbeitungsmaschine montiert wird. Die Basis kann sowohl eine Scheibe 10 (Fig. 3 und Fig. 4), oder eine Trommel 20 (Fig. 5 und Fig. 6) sein, welche jeweils durch einen Motor angetrieben werden. Die Bearbeitung des Bodenbelags 30 erfolgt durch paralleles Absenken der Basis, so dass durch das Eigengewicht derselben eine Mehrzahl solcher Federelemente 1 mit dem abrasiven Belag 2 auf dem Bodenbelag zum Eingriff kommt (Fig. 7 - Fig. 9).In Fig. 1 a spring element 1 is shown, which is mounted on a base of the tillage machine. The base can be both a disc 10 ( FIG. 3 and FIG. 4 ), or a drum 20 (FIG. Fig. 5 and Fig. 6 ), which are each driven by a motor. The processing of the floor covering 30 is effected by parallel lowering of the base, so that a plurality of such spring elements 1 with the abrasive coating 2 on the floor covering is engaged by the weight of the same ( Fig. 7-9 ).

Die Absenkung der Maschine, also das Annähern der Basis an den Bodenbelag, erfolgt entweder manuell, oder mittels einer mechanischen Vorrichtung. Je nach Grad der Absenkung B, (Fig. 7, Fig. 8 und Fig. 9) kann die Intensität der Bearbeitung beeinflusst werden. Mit sanfter Absenkung B erfolgt Feinbearbeitung des Bodenbelags 30 mit wenig Belastung auf dem Federelement 1 und kleiner Einfederung (Fig. 8). Bei voller Belastung und großer Einfederung B des Federelementes 1 wird die Bearbeitung des Bodenbelags 30 intensiver (Fig. 9). Je nach Teilbelastung (Fig. 8) erfolgt die Bearbeitung des Bodenbelages 30 mehr oder weniger intensiv. Die totale Einfederung des Federelementes 1 wird entweder durch das Eigengewicht, oder ein Zusatzgewicht auf der Bodenbearbeitungs-maschine erreicht werden. Im Extremfall, bis der federnde Teil 6 auf der Basis aufsteht (Fig. 9).The lowering of the machine, so the approach of the base to the floor, either manually, or by means of a mechanical device. Depending on the degree of lowering B, ( FIGS. 7, 8 and 9 ), the intensity of the processing can be influenced. With gentle lowering B is fine machining of the floor covering 30 with little load on the spring element 1 and small deflection ( Fig. 8 ). At full load and large deflection B of the spring element 1, the processing of the flooring 30 more intense ( Fig. 9 ). Depending on the partial load ( Fig. 8 ), the processing of the floor covering 30 is more or less intense. The total deflection of the spring element 1 is achieved either by its own weight, or an additional weight on the soil tillage machine. In extreme cases, until the resilient part 6 stands up on the base ( Fig. 9 ).

Mit einem starren Werkzeug kann ein Variieren der Belastung des Werkzeuges in einem größeren Bereich nicht erzielt werden. Bei zu großer Belastung verursacht ein starres Werkzeug in aller Regel deutliche Spuren im Bodenbelag 30. Dies kann bei voller Einfederung des Federelementes 1 auch geschehen (Fig. 9). Deshalb wird gemäß Erfindung der abrasive Belag 2 (Fig. 1) auf dem flexiblen Federelement 1 so aufgebracht, dass der abrasive Belag 2 über den ganzen Bereich der Einfederung mit unterschiedlicher Kraft den Bodenbelag 30 bearbeitet (Fig. 7, Fig. 8 und Fig. 9).With a rigid tool, varying the load on the tool over a wider range can not be achieved. If the load is too great, a rigid tool generally causes significant traces in the floor covering 30. This can also be done with full spring deflection of the spring element 1 ( Fig. 9 ). That's why According to the invention, the abrasive coating 2 ( Fig. 1 ) is applied to the flexible spring element 1 such that the abrasive covering 2 processes the floor covering 30 over the entire range of deflection with different force ( FIGS. 7, 8 and 9 ).

Um einen zusätzlichen Flexibilitätsgrad in der Kraft die auf den Bodenbelag wirken soll zu erreichen, wird also der abrasive Belag 2 auf dem federnden Teil 6, des Federelementes 1 direkt aufgebracht oder darauf befestigt. So erreicht man die erwünschte Flexibilität der Kraft, welche auf den abrasiven Belag 2 ausgeübt wird. Die Wirkung auf den Bodenbelag 30 kann so viel feiner variiert werden. Verschiedene Federelemente 1 können je nach Anwendung mit verschiedener Körnung des abrasiven Belags 2 versehen werden. Das Material des abrasiven Belags 2 kann grundsätzlich jedes abrasive Material sein. Üblich sind nebst andern Materialien Schmirgel, Hartmetall- und Diamantsplitter. Es kann aber auch aus einer Raspel oder einem Hobelwerkzeug bestehen, das auf dem Federelement 1 befestigt ist.In order to achieve an additional degree of flexibility in the force which is to act on the floor covering, so the abrasive coating 2 is applied directly to the resilient member 6, the spring element 1 or attached thereto. This achieves the desired flexibility of the force exerted on the abrasive pad 2. The effect on the floor covering 30 can be varied so much finer. Various spring elements 1 can be provided with different grain size of the abrasive coating 2, depending on the application. The material of the abrasive coating 2 can basically be any abrasive material. Usual are, among other materials emery, hard metal and diamond chips. But it can also consist of a rasp or a planing tool, which is mounted on the spring element 1.

Durch die Wahl der Dicke d des Federelementes 1 kann die Einfederung der Feder 4 des Federelementes 1 für die Wirkung auf den zu bearbeitenden Bodenbelag und dem Maschinengewicht angepasst werden. Bei einer Belastung von 4 - 10 Kg soll der federnde Teil 6 in der Regel ca. 2 - 6 mm einfedern. Dies wird nur erreicht, indem für die Herstellung des Federelementes 1 das richtige Material gewählt wird. Es ist durchaus denkbar, dass der Halter 5 eine andere Dicke d aufweist, als die Feder 4 und die Feder 4 ihrerseits kann über deren Ausdehnung ebenso verschiedene Dicken d aufweisen.By selecting the thickness d of the spring element 1, the deflection of the spring 4 of the spring element 1 can be adapted for the effect on the floor covering to be processed and the weight of the machine. At a load of 4 - 10 kg of the resilient member 6 is usually about 2 - 6 mm compress. This is achieved only by selecting the right material for the production of the spring element 1. It is quite conceivable that the holder 5 has a different thickness d, as the spring 4 and the spring 4 in turn may have different thicknesses d over the extent thereof.

Mehrere solcher Federelemente 1 werden lösbar auf einer Basis befestigt, damit sie im Bedarfsfall leicht gegen neue, unverbrauchte Federelemente 1 ausgewechselt werden können. Als Basis kann eine horizontal drehende Scheibe 10 dienen, wobei mindestens ein Federelement 1 innerhalb des Außendurchmessers 11 montiert ist (Fig. 3 und Fig. 4). Die Einfederung der Federelemente verhindert dabei allzu große Unterschiede in der Bearbeitungsintensität, falls die Scheibe 10 nicht wirklich parallel zum Bodenbelag 30 geführt würde. Die Scheibe 10 dreht mit tiefen Drehzahlen, von 150 - 1'000rpm.Several such spring elements 1 are releasably secured on a base, so that they can be easily replaced if necessary against new, unused spring elements 1. The base may be a horizontally rotating disc 10, wherein at least one spring element 1 is mounted within the outer diameter 11 ( FIG. 3 and FIG. 4 ). The deflection of the spring elements prevents too great Differences in the processing intensity, if the disc 10 would not really run parallel to the floor covering 30. The disc 10 rotates at low speeds, from 150 - 1'000rpm.

Eine weitere Möglichkeit ist die Montage von Federelementen 1 auf der Oberfläche 21 einer Trommel 20 (Fig. 5 und 6). Neben dem federnden Effekt, kann beim Einsatz mit einer Trommel mit der variierenden Drehzahl ein zusätzlicher Effekt erreicht werden. Je nach Drehzahl der Trommel 20 ist die Zentrifugalkraft unterschiedlich. Je höher die Drehzahl ist, desto stärker wirkt die Zentrifugalkraft auf die Einfederung des Federelementes 1. Als Regel gilt bei diesem Einsatz: Je höher die Drehzahl, desto stärker die Kraft die nötig ist, um die Einfederung des Federelementes 1 zu erreichen. Bei tiefer Drehzahl wirkt vor allem die Federkonstante der Feder 4.Another possibility is the assembly of spring elements 1 on the surface 21 of a drum 20 (FIG. FIGS. 5 and 6 ). In addition to the spring effect, when used with a drum with the varying speed an additional effect can be achieved. Depending on the rotational speed of the drum 20, the centrifugal force is different. The higher the speed, the stronger the centrifugal force acts on the deflection of the spring element 1. As a rule applies in this application: the higher the speed, the stronger the force that is necessary to achieve the deflection of the spring element 1. At low speed, especially the spring constant of the spring 4 acts.

Ist die Basis eine Scheibe 10, so dreht sie um eine vertikal angeordnete Antriebswelle, parallel zum Bodenbelag. Mit den darauf montierten Federelementen 1 korrespondierend (Fig. 4) weist eine solche Scheibe 10 Durchlässe 12 auf, durch welche der durch die Abrasion verursachte Staub abgesaugt werden kann. Mit der Aussparung 13 wird die Scheibe an der Welle des Motors befestigt.If the base is a disc 10, it rotates about a vertically arranged drive shaft, parallel to the floor covering. With the spring elements 1 mounted thereon corresponding ( Fig. 4 ) has such a disc 10 passages 12, through which the dust caused by the abrasion can be sucked. With the recess 13, the disc is fixed to the shaft of the motor.

Während die Scheibe 10 horizontal dreht, bewegt sich eine als Basis verwendete Trommel 20 parallel zum Bodenbelag 30 um eine horizontal angeordnete Achse, über welche die zentrale Halterung und Führung 21 der Trommel 20 erfolgt.As the disk 10 rotates horizontally, a base drum 20 moves parallel to the floor covering 30 about a horizontally disposed axis through which the central support and guide 21 of the drum 20 passes.
