Description

Die Erfindung betrifft einen Bestückungsteil für Walzenbürsten mit einem Halteteil für ein Bearbeitungselement zum Entfernen von Belägen, wie Schmutz, Schnee, Eis, Farbe und Gummiabrieb von Verkehrsflächen, wobei der Halteteil mit einem Schaft versehen ist, der an einem Ende eine Öffnung zur um eine zur Achse der Walzenbürste parallele, definierte Achse schwenkbeweg--lichen Lagerung des Halteteils am Kern der Walzenbürste und am anderen Ende einen das Bearbeitungselement aufnehmenden Kopf, der gegenüber dem Schaft des Halteteiles verdickt ausgebildet ist, aufweist.The invention relates to a component for roller brushes with a holding part for a processing element for removing deposits, such as dirt, snow, ice, paint and rubber abrasion from traffic areas, the holding part is provided with a shaft that has an opening at one end to one to The axis of the roller brush has a parallel, defined axis of pivotable mounting of the holding part on the core of the roller brush and, at the other end, a head which receives the processing element and is thickened relative to the shaft of the holding part.

Walzenbürsten sind in den verschiedensten Ausführungsformen bekannt.Roller brushes are known in a wide variety of embodiments.

So sind aus der DE-C-815 967, der GB-C-726 940 und den US-A-3 134 123, 3 200 430 und 3 228 053 Ausführungsformen für Walzenbürsten bekannt, bei welchen leistenförmige Halterungen für Borstenbüschel in achsparallele Nuten des Bürstenkörpers eingeschoben werden können. Bei diesen bekannten Rundbürsten sind die Borstenbüschel am Bürstenkörper nicht verschwenkbar gehaltert und können aus ihrer vom Bürstenkörper radial abstehenden Lage nur unter elastischer Verformung der Einzelborsten selbst abweichen.Thus, from DE-C-815 967, GB-C-726 940 and US-A-3 134 123, 3 200 430 and 3 228 053 embodiments for roller brushes are known, in which strip-shaped holders for tufts of bristles in axially parallel grooves of the Brush body can be inserted. In these known round brushes, the tufts of bristles are not held pivotably on the brush body and can only deviate from their position radially protruding from the brush body with elastic deformation of the individual bristles themselves.

Bei einer anderen Gruppe von Walzenbürsten sind die Borstenbüschel an einem im wesentlichen zylinderförmigen Trägerkörper (Bürstenkern) beweglich gelagert, wobei sich keine bevorzugte Schwenkachse der Borstenbüschel ergibt. So zeigt die DE-C-286 512 eine Rundbürste, bei der die Borstenbüschel am Bürstenkörper über Schraubenfedern in alle Richtungen verschwenkbar befestigt sind. Die DE-C-352 183 beschreibt eine als Mattschlagbürste dienende Rundbürste, bei der Borstenbüschel über mehrere Ringe nach beliebigen Richtungen beweglich an einem Trägerteil befestigt sind. Eine andere Möglichkeit einer nach allen Richtungen beweglichen Verbindung von Borstenbüscheln einer rotierenden Rundbürste mit deren Trägerkörper zeigt die DE-C-289 181, bei der Stifte mit verbreiterten Köpfen, an welchen die Borstenbüschel befestigt sind, durch Löcher im rohrförmigen Trägerteil greifen und dort durch die Köpfe gehalten sind. Aus der DE-C-286 513 ist es bekannt, bei einer Waschwalze für Straßenreinigungsmaschinen anstelle der Borsten Gummistreifen anzuordnen, die am Kern der Walzenbürste über Schraubenfedern und Muttern befestigt sind.In another group of roller brushes, the bristle tufts are movably mounted on an essentially cylindrical carrier body (brush core), with no preferred pivot axis of the bristle tufts. For example, DE-C-286 512 shows a round brush in which the tufts of bristles are attached to the brush body via coil springs so that they can pivot in all directions. DE-C-352 183 describes a round brush serving as a matte brush, in which tufts of bristles are fastened to a carrier part in several directions so as to be movable. Another possibility of connecting bristle tufts of a rotating round brush with its carrier body, which can be moved in all directions, is shown in DE-C-289 181, in which pins with widened heads, to which the bristle tufts are attached, reach through holes in the tubular carrier part and there through the Heads are held. From DE-C-286 513 it is known to arrange rubber strips instead of bristles in a washing roller for street cleaning machines, which are attached to the core of the roller brush by means of coil springs and nuts.

Aus der am 15. Feber 1985 bekanntgemachten österr. Patentanmeldung 100/84 ist eine Walzenbürste für Gleisbaumaschinen bekannt, bei der am Bürstenkern schlauchförmige Räumarme durch eine Klemm-Schraubverbindung befestigt sind. Die schlauchförmigen Räumarme sollen aus biegeelastischem Werkstoff bestehen und besitzen an ihren radial äußeren Enden keine einen erhöhten Verschleiß verhindernde Ausgestaltungen.From the Austrian patent application 100/84 published on February 15, 1985, a roller brush for track-laying machines is known, in which tubular broaching arms are attached to the brush core by a clamping screw connection. The tubular broaching arms are said to be made of flexible material and, at their radially outer ends, do not have any designs that prevent increased wear.

Es ist auch schon vorgeschlagen worden (vgl. die AT-B-305 350, US-A-3 278 966 und US-A-3 545 026), bei Rundbürsten Borsten um zur Drehachse der Bürste parallele Achsen verschwenkbar auszugestalten, wobei allerdings die Verschwenkbarkeit der Borsten lediglich dazu dient, die Borsten in einer bestimmten Winkellage zur Radialebene einzustellen. Ahnliches schlägt die US-A-3 545 026 vor, bei welcher die Verschwenkung der Borsten selbsttätig unter dem Anlagedruck der Walzenbürste am zu reinigenden Gegenstand erfolgen soll.It has also already been proposed (cf. AT-B-305 350, US-A-3 278 966 and US-A-3 545 026) to design bristles in the case of round brushes so as to be pivotable about axes parallel to the axis of rotation of the brush, although the Pivotal movement of the bristles only serves to set the bristles in a certain angular position to the radial plane. US-A-3 545 026 proposes a similar situation, in which the swiveling of the bristles is to take place automatically under the contact pressure of the roller brush on the object to be cleaned.

Durch die GB-C-962 604 ist es noch bekannt, Borstenbüschel am Kern einer Walzenbürste über dort vorgesehene Schellen und elastische Zwischenglieder zu befestigen, so daß die Borstenbüschel unter elastischer Verformung der Verbindungsglieder um zur Drehachse der Walzenbürste parallele Achse hin- und herfedern können Die in der GB-C-962 604 beschriebene Bürstenkonstruktion ist aber hinsichtlich der Befestigung der Borstenbüschel mit Schellen und mehrfachen Niet- bzw. Schraubenverbindungen sehr aufwendig, wobei sich überdies das Auswechseln abgenützter Borstenbüschel mühsam gestaltet.From GB-C-962 604 it is also known to attach bristle tufts to the core of a roller brush by means of clamps and elastic intermediate links provided there, so that the bristle tufts can spring back and forth with elastic deformation of the connecting links about the axis parallel to the axis of rotation of the roller brush The brush construction described in GB-C-962 604 is very expensive with regard to the attachment of the bristle tufts with clamps and multiple rivet or screw connections, and the replacement of worn bristle tufts is also tedious.

Nachteilig bei diesen bekannten Walzenbürsten ist es, daß vergleichsweise lange Borsten (Bearbeitungselemente) verwendet werden, die entsprechend elastisch und daher wenig verschleißfest ausgebildet sind.A disadvantage of these known roller brushes is that comparatively long bristles (processing elements) are used which are correspondingly elastic and therefore not very wear-resistant.

Die bekannten Rundbürsten haben den Nachteil, daß bei Auswahl des Werkstoffes für die Borsten ein Kompromiß zwischen Abriebfestigkeit und den für die bestimmungsgemäße Verwendung der Rundbürste erforderlichen elastischen Eigenschaften der Borsten gesucht werden muß.The known round brushes have the disadvantage that a compromise between abrasion resistance and the elastic properties of the bristles required for the intended use of the round brush must be sought when selecting the material for the bristles.

Die DE-A-3 246 118 beschreibt eine Vorrichtung zum Aufrauhen von Straßendecken, also zum Abtragen von Material von der Verkehrsfläche selbst. Hiezu wird u.a. eine Walze vorgeschlagen, an der Fräsmeißel befestigt sind. Die Fräsmeißel sind an der Walze bei der DE-A-3 246 118 über elastische Halter befestigt, die mit dem Umfang der Walze starr verbunden sind und zu dieser etwa tangential verlaufen.DE-A-3 246 118 describes a device for roughening road surfaces, i.e. for removing material from the traffic area itself. proposed a roller to which milling cutters are attached. The milling chisels are fastened to the roller in DE-A-3 246 118 via elastic holders which are rigidly connected to the circumference of the roller and are approximately tangential to it.

Im Dokument DE-B-1 210 409 ist eine Bürste beschrieben, bei der die Borstenbüschel in Stege eingesetzt sind, die über schmale Zungen an ein Band angeschlossen sind. Dabei sind die Stege, die Zungen und das Band einstückig aus elastischem Werkstoff gebildet.Document DE-B-1 210 409 describes a brush in which the tufts of bristles are inserted into webs which are connected to a band by means of narrow tongues. The webs, the tongues and the band are formed in one piece from elastic material.

Die US-A-4 332 422 offenbart eine Vorrichtung mit den Merkmalen des einleitenden Teils des unabhängigen Anspruches 1, die zum abtragenden Bearbeiten der Oberfläche von Straßenbelägen bestimmt ist und mit der die Straßenoberfläche eingeebnet werden soll. Bei der bekannten Vorrichtung sind die Halteteile an einem Bürstenkern um zur Achse des Bürstenkernes parallele Achsen verschwenkbar gelagert. Diese Halteteile sind in sich starr ausgebildet und besitzen einen Kopf, an dem Bearbeitungselemente vorgesehen sind. Die Halteteile üben eine mehrfache Hammerwirkung auf die zu bearbeitende Oberfläche aus, da sie nach dem erstmaligen Auftreffen auf die zu bearbeitende Oberfläche zwischen dieser und mit dem Bürstenkern verbundenen Anschlägen hin und her pendeln.US-A-4 332 422 discloses a device with the features of the introductory part of independent claim 1, which is intended for abrading the surface of road surfaces and with which the road surface is to be leveled. In the known device, the holding parts are mounted on a brush core so as to be pivotable about axes parallel to the axis of the brush core. These holding parts are rigid in themselves and have a head on which processing elements are provided. The holding parts have a multiple hammer effect on the surface to be machined, since they hit after the first impact oscillate the surface to be machined between this and the stops connected to the brush core.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, einen Bestückungsteil für Walzenbürsten der eingangs genannten Gattung anzugeben, bei dem die Bestückung, sei es nach Abnützung derselben oder um die Bestückung an den jeweiligen Einsatzzweck der Walzenbürste anzupassen, leicht ausgewechselt werden kann und zusätzlich die Halteteile um zur Drehachse der Walzenbürste parallele Achsen verschwenken können.In contrast, the invention has for its object to provide an equipment part for roller brushes of the type mentioned, in which the equipment, whether after wear and tear or to adapt the equipment to the particular application of the roller brush, can be easily replaced and additionally the holding parts to Axis of rotation of the roller brush can pivot parallel axes.

Erfindungsgemäß wird dies dadurch erreicht, daß der Halteteil einschließlich seines Schaftes und seines Kopfes, an dem das Bearbeitungselement vorgesehen ist, einstückig aus elastischem, vorzugsweise gummielastischem Werkstoff, ausgebildet ist, daß das Bearbeitungselement in einer im Kopf des Halteteiles vorgesehenen, parallel zur Achse der Öffnung des Schaftes verlaufenden Nut aufgenommen ist und daß das Bearbeitungselement in einer Halteschiene oder -leiste aufgenommen ist, die in der Nut des Kopfes des Halteteils eingesetzt und dort befestigt ist.According to the invention this is achieved in that the holding part including its shaft and its head, on which the processing element is provided, is formed in one piece from elastic, preferably rubber-elastic material, that the processing element in a provided in the head of the holding part, parallel to the axis of the opening of the shaft extending groove is received and that the processing element is received in a holding rail or bar, which is inserted into the groove of the head of the holding part and fastened there.

Ein wesentlicher Vorteil der Erfindung besteht darin, daß von den eigentlichen Bearbeitungselementen getrennte Halteteile vorgesehen sind, die zur Verbindung der Bearbeitungselemente mit dem Bürstenkörper dienen, so daß für den Halteteil einerseits und das Bearbeitungselement anderseits der jeweils geeignete Werkstoff verwendet werden kann. Da überdies die Halteteile an ihren radial außen liegenden Enden mit einem Kopf versehen sind, an dem die an der Oberfläche der zu bearbeitenden (Verkehrs-) Fläche angreifenden Bearbeitungselementen befestigt sind, kann der Abschnitt des Halteteiles, der dessen Kopf mit dem Bürstenkern verbindet, also der Schaft des Halteteiles, leicht und elastisch ausgebildet werden, wogegen die Bearbeitungselemente besonders verschleißfest bzw. in Entsprechung der ihnen zugeordneten Aufgabe ausgeführt werden können.A major advantage of the invention is that separate holding parts are provided from the actual machining elements, which are used to connect the machining elements to the brush body, so that the respective suitable material can be used for the holding part on the one hand and the machining element on the other hand. Since, moreover, the holding parts are provided at their radially outer ends with a head to which the machining elements engaging on the surface of the (traffic) surface to be worked are fastened, the section of the holding part which connects its head to the brush core can therefore the shaft of the holding part can be made light and elastic, whereas the machining elements can be carried out particularly wear-resistant or in accordance with the task assigned to them.

Durch die Erfindung ergibt sich der Vorteil, daß an die elastischen Eigenschaften der Bearbeitungselemente keine besonderen Anforderungen mehr gestellt werden, da die rohr-, stab- oder leistenförmigen Halteteile am Bürstenkern in Radialebenen verschwenkbar gelagert und elastisch ausgestaltet sind.The invention has the advantage that the elastic properties of the machining elements are no longer particularly demanding, since the tubular, rod-shaped or strip-shaped holding parts on the brush core are pivotably mounted in radial planes and are designed to be elastic.

Die Erfindung gestattet es weiters, die Halteteile von Walzenbürsten zu verändern und auch ein-und dieselbe Walzenbürste, falls dies für einen speziellen Verwendungszweck gewünscht wird, mit unterschiedlichen Bearbeitungselementen auszurüsten. Als Bearbeitungselemente können die üblichen Borstenbüschel (die aber dann nur mehr ganz kurz sind), Streifen aus elastischem Werkstoff, Stifte, insbesondere aus Hartstoff, und mehreckige Plättchen, die mit einer Seitenkante an der zu bearbeitenden Fläche angreifen, vorgesehen sein.The invention also makes it possible to change the holding parts of roller brushes and also to equip one and the same roller brush, if this is desired for a special purpose, with different processing elements. The usual bristle tufts (which are then only very short), strips of elastic material, pins, in particular of hard material, and polygonal plates, which engage with a side edge on the surface to be processed, can be provided as processing elements.

Der Kopf 3 und die Halterung 25 mit der Bohrung 26 sowie der Schaft 4 sind aus gummielastischem Werkstoff gebildet.The head 3 and the holder 25 with the bore 26 and the shaft 4 are made of rubber-elastic material.

Aus Figur 1 ist noch ersichtlich, daß die in einer zur Achse der Walzenbürste, an welche die Halteteile 1 gelagert sind, senkrechten Ebene liegenden Stifte 8 zur Längserstreckung des Halteteiles 1 geneigt verlaufen, wobei die freien Enden der Stifte 8 nach vorne, d.h. in Drehrichtung (Pfeil 12) weisen. Diese Schrägstellung der Stifte oder Borsten, und auch die im Bereich der Vorderfläche des Halteteiles 1 liegende Anordnung seines Schaftes 4 ergibt einen Halteteil, der drehrichtungsspezifisch ist. Für einen Halteteil, der für beide mögliche Drehrichtungen einer Rundbürste verwendbar ist, werden die Bearbeitungselemente 2 in Längsrichtung des Halteteiles 1 verlaufen und auch der Schaft 4 in der Längsmittelebene des Halteteiles 1 angeordnet sein.From Figure 1 it can also be seen that the pins 8 lying in a plane perpendicular to the axis of the roller brush on which the holding parts 1 are mounted are inclined to the longitudinal extent of the holding part 1, the free ends of the pins 8 being forward, i.e. point in the direction of rotation (arrow 12). This inclination of the pins or bristles, and also the arrangement of its shaft 4 in the region of the front surface of the holding part 1, results in a holding part that is specific to the direction of rotation. For a holding part that can be used for both possible directions of rotation of a round brush, the processing elements 2 will run in the longitudinal direction of the holding part 1 and the shaft 4 will also be arranged in the longitudinal center plane of the holding part 1.

Der Halteteil 1 gemäß Figur 2 weist einen in seiner Längsmittelebene angeordneten Schaft 4 auf. Der Kopf 3 besitzt eine im Querschnitt T-förmige Nut 9 zur Aufnahme von Bearbeitungselementen. Die Halterung 25 ist zur Verankerung an dem Kern einer Rundbürste mit einer Bohrung 26 versehen.The holding part 1 according to FIG. 2 has a shaft 4 arranged in its longitudinal center plane. The head 3 has a T-shaped groove 9 for receiving machining elements. The bracket 25 is provided for anchoring to the core of a round brush with a bore 26.

In Figur 3 ist das Ende einer Halteschiene 10 für Bearbeitungselemente 2 veranschaulicht, die einen T-förmigen Querschnitt aufweist, wobei ein Flansch 11 zur Verbindung mit vorzugsweise mehreren Köpfen 3 (nicht dargestellt) dient und die Stegteile 11 eine Nut 9 zur Aufnahme von Bearbeitungselementen 2 begrenzen. Diese Bearbeitungselemente 2 können gemäß Figur 4 aus Streifen 6 bestehen, die mit Hilfe von Schlitzen 7 kammförmig ausgebildet sind.In Figure 3, the end of a holding rail 10 for machining elements 2 is illustrated, which has a T-shaped cross section, wherein a Flange 11 is used for connection to preferably several heads 3 (not shown) and the web parts 11 define a groove 9 for receiving machining elements 2. According to FIG. 4, these processing elements 2 can consist of strips 6, which are comb-shaped with the aid of slots 7.

Die in Figur 4 veranschaulichte Halteleiste 15 ist im Querschnitt trapezförmig mit Seitenflächen 18 ausgebildet.The holding strip 15 illustrated in FIG. 4 is trapezoidal in cross section with side faces 18.

- In der Halteleiste 15 sind keilförmige Ausnehmungen 14 vorgesehen, in welche Bearbeitungselemente in Form von mehreckigen Plättchen 13 so eingesetzt werden können, daß die Plättchen 13 mit einer Seitenkante aus den Ausnehmungen 14 über die äußere Fläche 17 der Halteleiste 15 vorragen. Derartige Bearbeitungselemente haben z.B. eine trapezförmige Umrißform.- In the retaining strip 15 wedge-shaped recesses 14 are provided, in which processing elements in the form of polygonal plates 13 can be used so that the plates 13 protrude with a side edge from the recesses 14 over the outer surface 17 of the retaining strip 15. Such processing elements have e.g. a trapezoidal outline.
