Description

Die vorliegende Erfindung betrifft ein Werkzeug für das Abscheren und/oder Egalisieren von Oberflächen gemäss Oberbegriff des Patentanspruchs 1.The present invention relates to a tool for the shearing and / or leveling of surfaces according to the preamble of claim 1.

Zum Abscheren und/oder Egalisieren von Oberflächen werden je nach Beschaffenheit der abzutragenden Fläche oder des abzutragenden Materials verschiedene Werkzeuge verwendet. So werden z.B. für die Entfernung von Gummi auf Flugpisten, Strassenmarkierungen und das Egalisieren von rohen Betonböden Flächenfräsen, wie in Patent Nr.CH 307911 beschrieben, eingesetzt. Flächenfräsen dieser Art können auch für das mechanische Abtragen und Entfernen von Asphalt, Kunststoffbelägen und Teppichen eingesetzt werden.For shearing and / or leveling surfaces depending on the nature of the area to be removed or different material to be removed Tools used. For example, for the distance from rubber to runways, road markings and that Leveling of raw concrete floors surface milling, as in Patent No.CH 307911 described used. Surface milling of this type can also be used for mechanical removal and removal of asphalt, Plastic coverings and carpets are used.

Ferner sind auch Bodenfräsmaschinen bekannt, welche die Oberflächen mit Meissel Abscheren. Da Meissel aber nicht weichen, sich selbst aber richtiggehend in das Material "hineinfressen" erfordern mit Meissel bestückte Maschinen und Werkzeughalter sehr stabile und schwere Basisgeräte und Antriebe. Der Vorteil solcher Vorrichtungen ergibt sich in der Art des eigentlichen "fräsens". Ob der Belag hart, spröde, elastisch, zäh oder weich ist, die Meissel arbeiten sich durch und tragen das Material ab, indem es abgeschert, abgeschlagen oder abgefräst wird. Lediglich die Vortriebsgeschwindigkeit, muss der Oberflächenbeschaffenheit angepasst werden. Ein Problem stellt sich in der Anwendung dadurch, dass solche zu schwergewichtig sind , um in kleineren geschlossenen Räumen eingesetzt zu werden wie es der Wohnungsbau erforderdert.Floor milling machines are also known, which shear the surfaces with chisels. Since chisel not give way, but really right into that "Chewing" material with chisel required equipped machines and tool holders very stable and heavy basic devices and drives. The advantage such devices result in the type of actual "milling". Whether the surface is hard, brittle, is elastic, tough or soft, the chisels work through and remove the material by making it is sheared, chipped or milled. Only the speed of advance must be Surface quality can be adjusted. On The problem arises in the application that those too heavy are too small to be used in closed rooms like the Housing construction required.

Man behilft sich daher mit Flächenfräsen wie in Nr. CH 307911 vorgestellt, deren Werkzeuge nicht Meissel, sondern auf Wellen frei drehbar gelagerte Fräsräder sind. Eine Maschine für feinere Arbeiten ist in US 5,980,371 beschrieben. Die Fräsräder werden grundsätzlich in der gleichen Art eingesetzt, jedoch ist die ganze Maschine und Vorrichtung leichter, so dass auch Wände etc. mit diesem Werkzeug bearbeitet werden können. Bei allen diesen, motorisch angetriebenen Flächenfräsen sind innerhalb der Werkzeugträger Fräsräder so angeordnet, dass sie auf Achsen frei drehbar, die zu bearbeitende Fläche in der vorgesehenen Art berühren, d.h. dort "aufschlagen", und damit diese Fläche bearbeiten. Auf diesen Achsen sind wahlweise eine Mehrzahl von Fräsrädern gruppenweise aufgereiht. Maschinen dieser Art bearbeiten die Oberflachen indem sie eine definierte Schicht der Oberfläche "abschlagen". Mit der Kraft, welche erforderlich ist um die Fräsrädchen in Rotation zu versetzen (Impuls-Satz) schlägt das Werkzeug an der Oberfläche Teile ab.One therefore makes use of surface milling as in No. CH 307911, whose tools are not chisels, but milling wheels freely rotatable on shafts are. A machine for finer work is in US 5,980,371. The milling wheels are basically used in the same way, however the whole machine and device is lighter that walls etc. are also processed with this tool can be. In all of these, motorized driven surface milling are within the Tool carrier cutter wheels arranged so that they are on Axes freely rotatable, the area to be machined in the touch the intended type, i.e. "open" there, and work on this surface. On these axes are optionally a plurality of cutting wheels lined up in groups. Machines of this type edit the surfaces by defining one "Knock off" the surface layer. With the power which is required around the milling wheels in rotation the tool strikes at the Surface parts off.

Vorrichtungen die eine Oberfläche mittels "abschlagen" bearbeiten eignen sich jedoch nicht für den Abtrag von weichen, elastischen und zähen Belägen. Insbesondere das Entfernen von Teppichen ist praktisch unmöglich. Die Fasern der Teppiche, die widerstandsfähig und teilweise sehr renitent sind, wickeln sich um Achsen und Fräsräder, so dass diese nach kürzestem Einsatz blockiert sind. Elastische und zähe Beläge bringen lediglich die Fräsrädchen in Rotation, lassen sich aber sehr schwer abscheren. Im schlechtesten Fall erhitzen sich die Beläge und verunmöglichen den gewünschten Abtrag.Devices that "knock off" a surface However, editing is not suitable for the removal of soft, elastic and tough coverings. In particular removing carpets is practically impossible. The fibers of the carpets that are resistant and are sometimes very resistant, they wind around axes and cutting wheels so that they can be used in the shortest possible time are blocked. Bring elastic and tough coverings only the milling wheels in rotation, can be but shear very hard. In the worst case the pads heat up and make it impossible desired removal.

Anstelle solcher auf Achsen drehbar gehaltenen Fräsrädern können auch fest montierte Schleifklötze Verwendung finden. Diese sind aber für massivere, materialabtragende Arbeiten und für den Einsatz mit weichen Materialien nicht geeignet, weil sich die Schleifkopfflächen schnell zusetzen (verstopfen, verstocken). Für feine Egalisierungsarbeiten an harten und spröden Oberflächen finden sie jedoch Anwendung, weil die Oberflächenstruktur sich durch den Schliff eine feinere, regelmässige Oberflächenstruktur erarbeiten lässt.Instead of such rotatably held on axes Milling wheels can also use permanently mounted grinding blocks Find use. But these are for more massive, material-removing work and for use with soft materials not suitable because the Clog grinding head surfaces quickly (clog, harden). For fine leveling work on hard and brittle surfaces are used, because the surface structure is through the cut a finer, regular surface structure can be worked out.

Die vorliegende Erfindung stellt sich nunmehr die Aufgabe Werkzeuge für das Abscheren und/oder Egalisieren von Oberflächen ein Gerät der eingangs genannten Art derart zu verbessern, dass die Vorteile der bekannten Flächenfräsen erhalten bleiben, das Gerät aber vor allem für weiche, elastische und faserige Beläge wie etwa Teppiche, geklebte Beläge, etc. eingesetzt werden kann.The present invention now addresses the Task tools for shearing and / or Equalize surfaces a device at the beginning to improve the type mentioned so that the benefits the well-known surface milling remain, that Device especially for soft, elastic and fibrous coverings such as carpets, glued coverings, etc. can be used.

Die Figuren stellen bevorzugte Ausführungsbeispiele dar, welche mit der nachfolgenden Beschreibung erläutert werden. The figures represent preferred exemplary embodiments which with the following description are explained.

Werkzeuge 5 wie sie für die Bodenbearbeitung eingesetzt werden sind wie auf Figur 1 gezeigt vielfach in walzenförmige Halter 1 eingebaut. Klassischerweise wechseln sich auf einer Welle 3 aufgeschobene Scheiben 13 und Fräsrädchen 10 ab. Bei herkömmlichen Konstruktionen haben Fräsrädchen 10 und Scheiben 13 auf der Welle 3 relativ viel Spiel, damit sie sich frei drehen können. Im Einsatz für Beton, Asphalt und andere harte Beläge eignet sich diese Konstruktion bestens. Durch die Rotation des walzenförmigen Werkzeughalters 1 werden die Fräsrädchen immer wieder auf den bearbeitenden Belag aufgeschlagen und bearbeiten die Oberfläche, in dem der Aufprall der sie in Bewegung setzt an der Oberfläche Teile ausbrichtTools 5 like those for tillage are used as shown in Figure 1 often installed in roller-shaped holder 1. Classically change on a wave 3 slid on disks 13 and milling wheel 10. at conventional constructions have milling wheels 10 and Discs 13 on the shaft 3 a lot of play, so they can turn freely. In action for concrete, Asphalt and other hard surfaces are suitable Great construction. By rotating the cylindrical tool holder 1 are the Milling wheel on the machining surface again and again opened and edit the surface in which the impact that sets them in motion on the Surface parts breaks out

Im erfindungsgemässen Aufbau kann diese klassische Konstruktion keine Verwendung finden da zähe und elastische sowie textile Beläge sich nicht durch Abschlagen entfernen lassen. Die Idee der Erfindung ist es nun, im Werkzeug 5, das aus Fräsrädchen 10 und Scheiben 13 besteht mittels einer Spannvorrichtung 11 die Fräsrädchen 10 und die Scheiben 13 zwischen den Flanschen 4 so einzuspannen, dass sie sich nicht mehr frei drehen können. Die Aufgabe ist es also, die Länge 11 zwischen den Flanschen 4 beeinflussen zu können. In the construction according to the invention, this can be classic Construction are not used because tough and elastic and textile coverings do not get through Have it removed. The idea of the invention it is now, in tool 5, which consists of milling wheels 10 and Disks 13 are made by means of a clamping device 11 the milling wheels 10 and the disks 13 between the Flanges 4 to be clamped so that they are no longer can rotate freely. So the job is the length 11 influence between the flanges 4.

Dies wird durch die Spannvorrichtung 11 welche durch die aussen an den Flanschen angeordneten und sich am zentralen Rohr 21 abschliessenden und -stützenden Befestigungen 20 gehalten wird. Die Befestigungen 20 können derart verstellt werden, dass die Distanz D des Werkzeuges 5 unter Druck verringert werden kann, so dass Fräsrädchen 10 und Scheiben 13 nur unter gewissem Kraftaufwand gegenseitig drehbar sind. Flansche 4 Rohr 21 bilden eine zusammengeschweisste Einheit.This is done by the tensioning device 11 arranged on the outside of the flanges and on the central pipe 21 closing and supporting Mounts 20 is held. The fastenings 20 can be adjusted so that the distance D of the Tool 5 can be reduced under pressure, so that the milling wheel 10 and discs 13 only under certain conditions Force are mutually rotatable. 4 pipe flanges 21 form a welded unit.

Die oben beschriebene Konstruktion, wie das Werkzeug 5 mit einer variablen und unter Druck beeinflussbaren Distanz D konstruiert sein kann, ist lediglich ein Beispiel. Natürlich ist das aus Welle 3, Scheiben 13 und Fräsrädchen 10 bestehende Werkzeug 5 ohne weiteres auch in einer anderen konstruktiven Form denkbar. Welle 3 könnte zum Beispiel auch eine Schraube sein, welche auf der einen Seite mit dem Schraubenkopf und auf der andern Seite mittels einem Gewinde eine Spannvorrichtung 11 bedienen könnte. Dass diese Schraube dann in einer Halterung fixiert werden kann, die das Bearbeiten einer Oberfläche erlaubt, wird aus der Beschreibung und den Zeichnungen klar.The construction described above, like the tool 5 with a variable and influenceable under pressure Distance D can be constructed is only one Example. Of course this is from wave 3, disks 13 and milling wheel 10 existing tool 5 without further notice also conceivable in another constructive form. For example, shaft 3 could also be a screw which on one side with the screw head and on the other side by means of a thread Clamping device 11 could operate. That these Screw can then be fixed in a holder that allows editing a surface is turned off the description and the drawings clearly.

Eine solche Vorrichtung wie Werkzeug 5 in einem Körper gehalten werden könnten, zeigt Figur 2. Dieser zylindrische Werkzeughalter 2 dreht sich um eine vertikale Achse A und beschreibt so auf der zu bearbeitenden Oberfläche eine kreisförmige Bewegung. Um die Werkzeuge 5 mit diesem Werkzeughalter 4 wirksam einsetzen zu können muss dieser Werkzeughalter über die Oberfläche bewegt werden. Wenn dieser Werkzeughalter 2 ausgebildet ist wie in Figur 2 gezeigt, dann können seitlich am Umfang des zylindrischen Werkzeughalters 2 weitere Werkzeuge mit zur Achse A parallelen Wellen 3 - montiert werden. Ein derart ausgerüsteter Werkzeughalter 2 kann für Kleinarbeiten in Räumen eingesetzt werden und ist insbesondere auch in Ecken zwischen Boden und Wänden direkt einsetzbar. Diese Möglichkeit besteht für einen Werkzeughalter 1 gemäss Figur 1 im Einsatz nicht.Such a device as tool 5 in a body Figure 2 shows cylindrical tool holder 2 rotates one vertical axis A and so describes on the to machining surface a circular motion. To make the tools 5 effective with this tool holder 4 To be able to use this tool holder must the surface to be moved. If this Tool holder 2 is designed as in FIG. 2 shown, then laterally on the circumference of the cylindrical tool holder with 2 other tools Shafts 3 - parallel to axis A must be installed. On equipped tool holder 2 can for Small jobs are used in rooms especially in corners between the floor and walls can be used directly. This possibility exists for one Tool holder 1 according to FIG. 1 is not in use.

Der Werkzeugträger 2 wird wie in Figur 2 dargestellt, als kastenartiger, zylindrischer Hohlkörper ausgebildet. In diesem Hohlkörper werden die Achsen 3 und die darauf sich befindenden Werkzeuge 5 sowohl parallel zur Fläche des Zylinders als auch parallel zum Umfang respektive zur zentralen Achse des zylindrischen Körpers angeordnet. Auf diese Weise können für relativ kleine Werkzeughalter eine Vielzahl Werkzeuge 5 eingebaut werden. Wie oben beschrieben ermöglicht ein solcher Werkzeughalter 2 den Einsatz für Flächen und Seitenwände. Mittels zylinderartigem Werkzeughalter können Ecken eines Raumes effizient bearbeitet werden.The tool carrier 2 is shown as in FIG. 2, as a box-like, cylindrical hollow body educated. The axes 3 and the tools 5 on it both parallel to the surface of the cylinder as well as parallel to the extent or to the central axis of the cylindrical body arranged. In this way can do a variety for relatively small tool holders Tools 5 are installed. As described above Such a tool holder 2 enables use for surfaces and side walls. By means of cylindrical Tool holders can make corners of a room efficient to be edited.

Der Aufbau eines solchen "Käfigs" ist in Figur 3 gezeigt. Für die Wellen 3 sind sowohl senkrechte, das heisst zur Achse A parallele Anordnungen als auch vom Mittelpunkt des Zylinders zur Peripherie gehende Anordnungen wie mit 3- angedeutet denkbar. In Figur 4 ist dargestellt wie die Werkzeuge 5 und die Achsen der Wellen 3 respektive 3 - angeordnet sind. Das abgetragene Material setzt sich im "Käfig" ab, wenn nicht durch eine Vielzahl von Autstrittsöffnungen 30 derselbe abgesogen werden kann.The structure of such a "cage" is shown in FIG. 3 shown. For the waves 3 are both vertical, that means arrangements parallel to axis A as well as from Center of the cylinder going to the periphery Arrangements as indicated with 3 conceivable. In Figure 4 is shown as the tools 5 and the axes of the Waves 3 and 3 - are arranged. The removed material settles in the "cage" when not through a plurality of outlet openings 30 the same can be sucked off.

Das Werkzeug 5 setzt sich wie in Figur 5 gezeigt aus einer Welle 3 auf die die Fräsrädchen 10 die Scheiben 12 aufgereiht sind. Die Welle 3 hat am einen Ende einen Kopf 6 und am andern Ende ein Gewinde 7. Auf diesem Gewinde 7 ist eine Mutter 8 montiert, mit deren Hilfe die Distanz zwischen dem Kopf 6 und der Mutter 8 so verringert werden kann das mit entsprechendem Druck der Widerstand zwischen den einzelnen Teilen (Fräsrädchen 10 und Scheiben 12) beeinflusst werden kann. Je nach Kraft die verwendet wird um Fräsrädchen 10 und Scheiben 12 aneinander zu pressen ergibt sich die Kraft, mit der das Werkzeug 5, respektive die Fräsrädchen 10 Material aus elastischem, zähem und textilem Material herausreissen können. Es ist eine Tatsache das nicht jede faserige oder elastische Oberfläche mit derselben Kraft bearbeitet werden muss. Deshalb ist die Verstellbarkeit des Anpressdruckes ein wesentlicher Faktor für die Vielseitigkeit in der das Werkzeug eingesetzt werden kann.The tool 5 is exposed as shown in FIG. 5 a shaft 3 on which the milling wheels 10 the disks 12 are lined up. The shaft 3 has one end a head 6 and a thread 7 at the other end this thread 7 a nut 8 is mounted, with the Help the distance between the head 6 and the mother 8 this can be reduced with appropriate pressure the resistance between the individual parts (Milling wheel 10 and disks 12) can be influenced can. Depending on the force that is used around milling wheels 10 and disks 12 to press against each other results the force with which the tool 5 or the Milling wheel 10 material made of elastic, tough and can tear out textile material. It is one The fact that not every fibrous or elastic Surface must be processed with the same force. Therefore the adjustability of the contact pressure is a essential factor for the versatility in the Tool can be used.

Naturgemäss können für das Werkzeug 5 verschiedenartige Fräsrädchen 10 , messerartige Rondellen, verschiedene Schrauben und Wellen 3 sowie ganz unterschiedliche Scheiben 12 verwendet werden. In Figur 6 ist dargestellt wie zum Beispiel zwischen den Fräsrädchen 8 anstelle normaler Scheiben auch Tellerfedern 14 Verwendung finden. Mit dem Einsatz von Tellerfedern 14 kann der Spannungsbereich der durch eine Spannvorrichtung 11 erzeugt wird erweitert werden. Er geht dann vom losen Spiel bis zur maximalen Pressung und hat einen Kraftverlauf gemäss der Federkonstante der Tellerfedern 14, mit der die Fräsrädchen 10 aneinandergepresst werden.Of course, 5 different milling wheels 10, knife-like Rondelles, various screws and shafts 3 as well completely different discs 12 are used. In Figure 6 is shown as for example between the Milling wheel 8 instead of normal discs too Disc springs 14 are used. With the use of Disc springs 14 can range from the voltage a tensioning device 11 generated is expanded become. It then goes from loose play to the maximum Pressing and has a force curve according to the Spring constant of the plate springs 14 with which the Milling wheels 10 are pressed together.

Varianten wie mit Tellerfedern 14 vorgegangen werden kann sind in der Figur 7 dargestellt, in der bei gleicher Federkonstante der Tellerfedern 14 der Weg über den die Pressung vor sich geht verlängert wird. In Figur 8 sind die Tellerfedern 14 so angeordnet , dass die Kraft die sie ausüben verdoppelt wird.Variants of how to proceed with disc springs 14 can be shown in Figure 7, in which same spring constant of the disc springs 14 the way over which the pressing is going to be extended. In Figure 8, the plate springs 14 are arranged that the force they exert is doubled.

Anstatt zwischen den Fräsrädchen 10 nur einfache metallische Scheiben 13 einzusetzen kann zwischen den Scheiben noch ein Gleitring 15 eingesetzt werden. Dieser hat zur Folge, dass die Reibung zwischen den metallischen Fräsrädchen 10 und den metallischen Scheiben 13 durch einen Gleitring 15 reduziert und ein Anfressen oder Abscheren etc. vermeiden kann (Figur 9). Solche Gleitringe 15 sind vorteilhafterweise aus Material gefertigt, wie es für Bremsscheiben oder Kupplungsbeläge verwendet wird. Einesteils soll das Material ein klar definiertes Gleiten erlauben, anderseits soll es aber natürlich auch beim Gleiten einen gewissen Widerstand erzeugen. Vor allem sollen aber diese Gleitscheiben 15 und weniger die Seiten der Fräsrädchen 10 verschleissen.Instead of just simple between the milling wheels 10 metallic washers 13 can be used between the Slices still a sliding ring 15 are used. As a result, the friction between the metallic milling wheel 10 and the metallic Discs 13 reduced by a slide ring 15 and a Can avoid seizing or shearing etc. (fig 9). Such sliding rings 15 are advantageously made of Made of material like it for brake discs or Clutch pads are used. Partly that should Allow material to be clearly defined, on the other hand, of course, it should also be when gliding generate some resistance. Above all, should but these sliding washers 15 and less the sides of the Wear milling wheel 10.

Zwischen den Fräsrädchen 10 können aber auch Kombinationen wie sie in Figur 10 dargestellt sind eingesetzt werden. Dabei verwendet man Gleitscheiben 15, metallische Scheiben 13 und Tellerfedern 14 je nach Einsatz. Solche Kombinationen ermöglichen nicht nur den gezielten Einsatz für die Anwendung, sondern sie ermöglichen auch, durch den Einsatz der Gleitscheiben, klar definierte Belastungen vorzusehen, bei denen die Fräsrädchen 10 dann eben an den Gleitscheiben zu Gleiten beginnen um sich auf der Welle 3 drehen.Between the milling wheels 10 can also Combinations as shown in Figure 10 be used. Slide washers are used 15, metallic washers 13 and Belleville washers 14 each after use.
