Description

Die vorliegende Erfindung betrifft ein Werkzeug für das Abscheren und/oder Egalisieren von Oberflächen gemäss Oberbegriff des Patentanspruchs, wie es beispielswise aus der US 4 040 668 bekannt ist.The present invention relates to a tool for the shearing and / or leveling of surfaces according to the preamble of the claim, as known for example from US 4 040 668.

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 the material to be removed different Tools used. Thus, e.g. for the distance of rubber on runways, road markings and the Leveling of raw concrete floors Surface milling, as in Patent No. CH 307911 described used. Surface milling of this kind can also for the 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.Furthermore, ground milling machines are known which Shearing the surfaces with chisel. There chisel but do not give way, but really into the To "eat in" material with chisel stocked machines and tool holder very stable and heavy base units and drives. The advantage Such devices results in the nature of actual "milling". Whether the coating hard, brittle, elastic, tough or soft, the chisels work go through and wear the material off by yourself sheared off, cut off or milled off. Only the propulsion speed, the must Surface texture to be adjusted. One Problem arises in the application in that those are too heavy to be smaller in size to be used in closed rooms like the Housing 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.Therefore you can use surface milling machines like in CH 307911, whose tools are not chisels, but on shafts freely rotatably mounted cutting wheels are. A machine for finer works is in US 5,980,371. The cutting wheels are basically used in the same way, however the whole machine and device is lighter, so that even walls etc. edited with this tool can be. In all these, motor powered surface milling machines are within the Tool carrier cutting wheels arranged so that they are on Axes freely rotatable, the surface to be machined in the touched, i. "open" there, and edit this area. On these axes are optionally a plurality of cutting wheels strung in groups. Machines of this kind edit the surfaces by defining a defined Layer the surface "knock off". With the power, which is required to rotate the milling wheels to offset (impulse set) hits the tool on 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 which "knock off" a surface edit are not suitable for the removal of soft, elastic and tough coverings. Especially The removal of carpets is virtually impossible. The fibers of the carpets, the resistant and sometimes very restless, wrap around axes and cutting wheels, so this after the shortest use are blocked. Bring elastic and tough coverings only the milling wheels in rotation, can be but very difficult to shave off. 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 on axes held rotatably Milling wheels can also be permanently mounted sanding blocks Find use. But these are for more massive, material-removing work and for use with soft materials are not suitable, because the Add grinding head surfaces quickly (clog, harden). For fine leveling work on hard and brittle surfaces, however, they find application, because the surface structure is characterized by the cut a finer, regular surface texture work 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 turns the Task tools for shearing and / or Leveling surfaces of a device of the beginning mentioned type to improve the benefits the known surface milling remain, the But 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 embodiments which, with the following description be 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 as for the tillage can be used as shown in Figure 1 often installed in cylindrical holder 1. Classically, alternating on a wave 3 deferred discs 13 and 10 milling wheels. at conventional constructions have milling wheels 10 and Slices 13 on the shaft 3 relatively much play, so they can turn freely. In use for concrete, Asphalt and other hard rubbers are suitable Construction very well. Through the rotation of the cylindrical tool holder 1 are the Milling wheel repeatedly on the processing surface open and edit the surface in which the impact that sets them in motion 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 inventive structure, this classic Construction does not find use because tough and elastic as well as textile coverings do not get through Remove the beating. The idea of the invention it is now, in the tool 5, the milling wheel 10 and Slices 13 is by means of a tensioning device 11 the Fräsrädchen 10 and the discs 13 between the Tighten flanges 4 so that they no longer work can rotate freely. So the task is the length 11 between the flanges 4 can influence.

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 which the outside arranged on the flanges and on central tube 21 final and supporting Fasteners 20 is held. The fortifications 20 can be adjusted so that the distance D of Tool 5 can be reduced under pressure, so that milling wheel 10 and 13 discs only under some Force are mutually rotatable. Flanges 4 pipe 21 form a welded together 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 under pressure influenced Distance D can be constructed is only one Example. Of course this is from wave 3, slices 13 and milling 10 existing tool 5 easily also conceivable in another constructive form. Wave 3 could also be a screw, for example which on one side with the screw head and on the other side by means of a thread one Clamp 11 could operate. That these Screw can then be fixed in a bracket, which allows the editing of a surface, will be out 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 could be held, Figure 2 shows this cylindrical tool holder 2 rotates around a vertical axis A and thus describes on the to working surface a circular motion. To the tools 5 with this tool holder 4 effective to be able to use this tool holder over the surface will be moved. If this Tool holder 2 is formed as in Figure 2 shown, then can laterally on the circumference of cylindrical tool holder 2 more tools with to the axis A parallel shafts 3 - are mounted. One such equipped tool holder 2 can for Small work in rooms is and is used especially in corners between floor and walls directly usable. This possibility exists for one Tool holder 1 according to Figure 1 in use not.

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 in FIG. 2, as a box-like, cylindrical hollow body educated. In this hollow body, the axes are the third and the tools 5 thereon both parallel to the surface of the cylinder as well as parallel to the extent or to the central axis of the arranged cylindrical body. In this way can do a variety for relatively small tool holders Tools 5 are installed. As described above allows such a tool holder 2 the use for surfaces and sidewalls. By means of cylinder-like Tool holders can efficiently move corners of a room 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, the means to the axis A parallel arrangements as well as from Center of the cylinder going to the periphery Arrangements as indicated by 3- conceivable conceivable. In FIG. 4 is shown as the tools 5 and the axes of Shafts 3 respectively 3 - are arranged. The eroded material settles in the "cage", though not by a plurality of Autstrittsöffnungen 30th 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 set out as shown in FIG a shaft 3 on the milling wheel 10, the discs 12 are lined up. The shaft 3 has one end a head 6 and at the other end a thread 7. On this thread 7 is a nut 8 is mounted, with their Help the distance between the head 6 and the mother 8 so can be reduced with the appropriate pressure the resistance between the parts (Milling 10 and 12 slices) are affected can. Depending on the force used to milling wheels 10 and 12 slices to press together the force with which the tool 5, respectively the Milling wheel 10 Material made of elastic, tough and can tear out textile material. It is one That's not all 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 that 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.Naturally, for the tool 5 various types of milling wheels 10, knife-like Rondelles, various screws and shafts 3 as well very different slices 12 are used. In FIG. 6 is shown as between, for example Milling wheel 8 instead of normal disks also Disc springs 14 use find. With the use of Disc springs 14, the voltage range of a clamping device 11 is generated expanded become. He then goes from the loose game to the maximum Pressing and has a force curve according to the Spring constant of the cup springs 14, with which the Milling wheel 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 are how to proceed with disc springs 14 can be shown in the figure 7, in the at same spring constant of the plate springs 14 the way over which the pressing is going on is extended. In Figure 8, the plate springs 14 are arranged so that the power they exercise 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 between the milling 10 only simple metallic discs 13 can use between the Slices still a sliding ring 15 are used. This has the consequence that the friction between the metallic milling wheel 10 and the metallic Slices 13 reduced by a slide ring 15 and a Can avoid seizure or shearing etc. (FIG 9). Such slip rings 15 are advantageously made Material, as it is for brake discs or Clutch pads is used. On the one hand, this is supposed to be Material allow a clearly defined glide, On the other hand, it should of course also when gliding create a certain resistance. Above all else but these sliders 15 and less the sides of the Milling wheel 10 wear.

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.But between the milling 10 can also Combinations as shown in Figure 10 be used. Here you use sliding washers 15, metallic discs 13 and disc springs 14 each after use. Such combinations do not allow only targeted use for the application, but They also allow, through the use of To provide sliding washers, clearly defined loads, in which the milling 10 then just to the Sliding slides start to slip on the Turn shaft 3.
