Abstract

A brush roll, comprising a hollow cylinder which is held in bearings at its ends, rotates about its axis and is provided with a bristle set consisting of radially outwardly projecting bristles in the region of its outer circumference, the hollow cylinder (2) consisting of a polymer material. <IMAGE>

Description

Die Erfindung betrifft eine Bürstenwalze, umfassend eine stirnseitige in Lagern gehaltenen und um seine Achse rotierenden Hohlzylinder, der im Bereich seines Außenumfangs mit einem Besatz aus radial nach außen vorstehenden Borsten versehen ist.The invention relates to a brush roller, comprising a hollow cylinder on the end, which is held in bearings and rotates about its axis and is provided in the region of its outer circumference with a set of bristles projecting radially outwards.

Ein solche Bürstenwalze ist bekannt. Sie besteht aus Metall und hat ein äußerst hohes Trägheitsmoment, was große Kräfte beim Beschleunigen und Abbremsen erfordert.Such a brush roller is known. It is made of metal and has an extremely high moment of inertia, which requires great forces when accelerating and braking.

Der Erfindung liegt die Aufgabe zugrunde, eine solche Bürstenwalze derart weiterzuentwickeln, daß es gelingt, bei geringerem Kraftbedarf bessere Beschleunigungs- und Abbremswerte zu erzielen.The invention has for its object to develop such a brush roller so that it is possible to achieve better acceleration and deceleration values with less power.

Diese Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen von Anspruch 1 gelöst. Auf vorteilhafte Ausgestaltungen nehmen die Unteransprüche Bezug.This object is achieved with the characterizing features of claim 1. The subclaims refer to advantageous refinements.

Bei der erfindungsgemäßen Bürstenwalze ist es vorgesehen, daß der Hohlzylinder aus einem polymeren Werkstoff besteht. Die Trägheitsmasse der Bürstenwalze ist dadurch stark vermindert, was es erlaubt, große Beschleunigungen und Abbremsungen mit kleinem Energieaufwand zu verwirklichen.In the brush roller according to the invention it is provided that the hollow cylinder consists of a polymeric material. The mass of inertia of the brush roller is thereby greatly reduced, which allows large accelerations and decelerations to be achieved with a small expenditure of energy.

Wenn die Borsten auf dem Hohlzylinder unsymmetrisch verteilt sind, besteht die Möglichkeit, daß der Hohlzylinder zumindest ein metallisches Gegengewicht auf der den Borsten radial gegenüberliegenden Seite aufweist, das in seine Wandung eingebettet ist. Das Gegengewicht tritt bei einer solchen Ausführung nicht nach außen in Erscheinung, wodurch das Auswuchten vereinfacht ist und Unfallgefahren vermieden werden. Das Gegengewicht kann die durch die unsymmetrische Verteilung der Borsten erzeugte Unwucht auch völlig kompensieren.If the bristles are distributed asymmetrically on the hollow cylinder, there is the possibility that the hollow cylinder has at least one metallic counterweight on the radially opposite side of the bristles, which is embedded in its wall. The counterweight does not appear to the outside in such a design, which simplifies balancing and risk of accidents be avoided. The counterweight can also fully compensate for the imbalance caused by the asymmetrical distribution of the bristles.

Bürstenwalzen mit einer unsymmetrischen Verteilung der Borsten gelangen beispielsweise in Bogenanlegern von Druckmaschinen zur Anwendung. Sie sind gewöhnlich nur mit einer einzigen Reihe von Borsten versehen, die an einer Umfangsstelle angebracht ist. Das Gegengewicht ist bei solchen Ausführungen zweckmäßig von streifenförmiger Gestalt und parallel zu den Borsten verlaufend angebracht.Brush rollers with an asymmetrical distribution of the bristles are used, for example, in sheet feeders of printing presses. They are usually only provided with a single row of bristles, which is attached at a peripheral location. In such designs, the counterweight is expediently of a strip-like shape and runs parallel to the bristles.

Der polymere Werkstoff, aus dem der Hohlzylinder erzeugt ist, kann durch darin eingebettete Fasern und/oder Fäden verstärkt sein. Hierdurch lassen sich die Festigkeitseigenschaften merklich vergrößern, insbesondere bei Ausführungen, bei denen Fasern und/oder Fäden einer höheren Festigkeit zur Anwendung gelangen, beispielsweise solche aus Kohlenstoff und/oder Glas. Der Walzenkörper besteht bevorzugt aus Epoxyd- oder Phenolharz.The polymeric material from which the hollow cylinder is produced can be reinforced by fibers and / or threads embedded therein. This allows the strength properties to be markedly increased, in particular in the case of designs in which fibers and / or threads of higher strength are used, for example those made of carbon and / or glass. The roller body is preferably made of epoxy or phenolic resin.

Um den Austausch der Borsten nach eingetretenem Verschleiß zu vereinfachen, hat es sich als vorteilhaft bewährt, wenn die Borsten mit Gewindeaufnahmen versehen sind, die in den Hohlzylinder einschraubbar sind. Hiervon abweichende Methoden zur Festlegung der Borsten sind selbstverständlich ebenfalls möglich.In order to simplify the replacement of the bristles after wear has occurred, it has proven to be advantageous if the bristles are provided with threaded receptacles that can be screwed into the hollow cylinder. Different methods for fixing the bristles are of course also possible.

Die Erfindung wir nachfolgend anhand der Zeichnungen weiter verdeutlicht.The invention is illustrated below with the aid of the drawings.

Es zeigen:

  • Fig. 1 eine Bürstenwalze in quergeschnittener Darstellung.
  • Fig. 2 die Bürstenwalze nach Fig. 1 in längsgeschnittener Darstellung.
Show it:
  • Fig. 1 is a brush roller in a cross-sectional view.
  • Fig. 2 shows the brush roller of FIG. 1 in a longitudinal section.

Die in Fig. 1 gezeigte Bürstenwalze besteht aus einem um seine Achse rotierbaren Hohlzylinder 2, der aus Epoxydharz besteht und durch darin eingelagerte Fasern 5 verstärkt ist. Der Hohlzylinder 2 ist an einer Umfangsstelle mit einer sich parallel zur seiner Achse erstreckenden Reihe von Borsten 3 versehen, die in Gewindestiften 6 gehalten sind und mittels der Gewindestifte 6 durch Einschrauben in Gewindebohrungen des Hohlzylinders 2 gehaltert sind.The brush roller shown in Fig. 1 consists of a hollow cylinder 2 rotatable about its axis, which consists of epoxy resin and is reinforced by fibers 5 embedded therein. The hollow cylinder 2 is at a circumferential location with one parallel to its axis extending row of bristles 3, which are held in grub screws 6 and are held by means of the grub screws 6 by screwing into threaded holes of the hollow cylinder 2.

Der Hohlzylinder 2 weist auf der den Borsten 3 radial gegenüberliegenden Seite ein metallisches Gegengewicht 4 auf, das in seine Wandung eingebettet ist und das aus einem Blechstreifen aus Stahl besteht. Das Gegengewicht 4 ist so bemessen dimensioniert, daß es von außen nicht erkennbar ist. Die Auswuchtung und Lagerung des Hohlzylinder 2 ist dadurch stark vereinfacht. Desweiteren ist der Entstehung von Unfallgefahren in optimaler Weise vorgebeugt.The hollow cylinder 2 has on the radially opposite side of the bristles 3 a metallic counterweight 4 which is embedded in its wall and which consists of a sheet metal strip made of steel. The counterweight 4 is dimensioned such that it cannot be seen from the outside. The balancing and storage of the hollow cylinder 2 is greatly simplified. Furthermore, the occurrence of accident hazards is optimally prevented.

In Fig. 2 ist die Bürstenwalze gemäß Fig. 1 in längsgeschnittener Darstellung wiedergegeben. Die stirnseitige Lagerung 1 besteht bei dem gezeigten Ausführungsbeispiel aus Lagerschilden, die mit dem Hohlzylinder 2 verklebt und ihrerseits in Blocklagern aufgenommen sind. Abweichende Ausführungen von Lagerungen sind selbstverständlich ebenfalls möglich.In Fig. 2 the brush roller according to FIG. 1 is shown in a longitudinal section. The end bearing 1 in the embodiment shown consists of end shields which are glued to the hollow cylinder 2 and in turn are accommodated in block bearings. Different designs of bearings are of course also possible.
