- the end rings 3, 4 can be rotatably mounted on a shaft. The fact that they have a contour which is adapted to the slopes on the end faces of the brush element 2, this can be done via a rotationally fixed fixation on the shaft.
- the Fig. 2 shows a similar arrangement as the Fig. 1 , with the difference that no body 10 is provided. Otherwise, the same elements are provided, which therefore also carry the same reference numerals.
Abstract
Description
Die Erfindung betrifft eine Rotationsbürste zur Reinigung eines Druckzylinders einer Druckmaschine mit einem einen Borstenbesatz aufweisenden Bürstenelement, wobei die Borsten des Borstenelements gleich lang sind.The invention relates to a rotary brush for cleaning a printing cylinder of a printing press with a brush element having a bristle element, wherein the bristles of the bristle element are the same length.
Aus der
Der Austausch solcher Bürstenelemente erfordert es, dass die Bürstenanordnung zerlegt und anschließend wieder zusammengebaut wird. Dies kann insbesondere bei Druckmaschinen, die hohe Druckzahlen erreichen müssen, zu umständlich und langwierig sein.The replacement of such brush elements requires that the brush assembly be disassembled and then reassembled. This can be too cumbersome and tedious, especially for printing presses which have to achieve high printing numbers.
Aufgabe der vorliegenden Erfindung ist es deshalb, eine Rotationsbürste bereitzustellen, die diesbezüglich Abhilfe schafft.Object of the present invention is therefore to provide a rotary brush, which provides relief in this regard.
Gelöst wird diese Aufgabe durch eine Rotationsbürste der eingangs genannten Art, wobei in einem oder den axialen Endbereichen des Bürstenelements verschleißfestere, härtere und/oder steifere Borsten vorgesehen sind als in einem axialen mittleren Bereich des Bürstenelements. Somit kann das Bürstenelement so ausgestaltet werden, dass in einem Bereich, in dem eine erhöhte Beanspruchung zu erwarten ist, ein anderer Borstenbesatz gewählt wird, sodass die Bürste an dieser Stelle nicht so stark verschleißt und ein Austausch des Bürstenelements erst später notwendig wird.This object is achieved by a rotary brush of the type mentioned above, wherein wear-resistant, harder and / or stiffer bristles are provided in one or the axial end regions of the brush element than in an axial central region of the brush element. Thus, the brush element can be designed so that in a region in which an increased stress is expected, a different bristle trim is selected, so that the brush at this point does not wear so much and replacement of the brush element will be necessary later.
Gemäß einer bevorzugten Ausführungsform kann vorgesehen sein, dass zwei Bereiche vorgesehen sind, deren Borstenbesatz andere Eigenschaften aufweist als der verbleibende Bereich des Bürstenelements. Insbesondere können der oder die zwei Bereiche mit anderen Eigenschaften des Borstenbesatzes am Ende des Bürstenelements angeordnet sein. Dies hat insbesondere Vorteile bei der Reinigung von Druckwalzen, da diese an ihren Enden in der Regel eine stärkere Verschmutzung aufweisen. Wenn demnach die Rotationsbürste so ausgestaltet wird, dass die Endbereiche mit einem anderen Besatz ausgestattet sind, der verschleißfester ist, so kann die Lebensdauer der Bürsten dadurch verlängert werden.According to a preferred embodiment it can be provided that two areas are provided, whose bristle stock has different properties than the remaining area of the brush element. In particular, the one or two regions with different properties of the bristle lining may be arranged at the end of the brush element. This has particular advantages in the cleaning of pressure rollers, since they usually have more pollution at their ends. Accordingly, if the rotary brush is designed so that the end portions are provided with another garnish which is more wear-resistant, the life of the brushes can thereby be prolonged.
In diesem Zusammenhang ist es vorteilhaft, wenn an beiden Enden des Bürstenelements der Borstenbesatz andere Eigenschaften aufweist als im zwischen den Enden liegenden Bereich des Bürstenelements.In this context, it is advantageous if the bristle facing has different properties at both ends of the brush element than in the region of the brush element lying between the ends.
Besonders vorteilhaft ist es, wenn der Borstenbesatz an den Enden des Bürstenelements dieselben Eigenschaften aufweist. Dadurch muss beim Einbau des Bürstenelements nicht auf dessen Orientierung geachtet werden. Die Reinigungswirkung ist an beiden Enden des Bürstenelements gleich.It is particularly advantageous if the bristle lining has the same properties at the ends of the brush element. As a result, care must be taken when installing the brush element on its orientation. The cleaning effect is the same at both ends of the brush element.
Gemäß einer besonders bevorzugten Ausführungsform kann vorgesehen sein, dass bezogen auf die Länge des Bürstenelements an den Enden jeweils ein Bereich < 20 % einen Borstenbesatz mit anderen Eigenschaften aufweist. Dabei kann der Bereich am Ende < 15 % oder < 10 % sein. Je nach zu reinigendem Druckzylinder kann die Größe des Bereichs gewählt und eingestellt werden.According to a particularly preferred embodiment, it may be provided that, with reference to the length of the brush element at the ends, an area <20% in each case has a bristle facing with different properties. The range at the end can be <15% or <10%. Depending on the pressure cylinder to be cleaned, the size of the area can be selected and adjusted.
Besondere Vorteile ergeben sich, wenn lediglich ein Bürstenelement vorgesehen ist. Dies bedeutet, dass die gesamte Rotationsbürste ausgetauscht werden kann. Der Austausch ist dadurch schneller als in dem Fall, in dem die Rotationsbürste auseinandergebaut werden muss und nur einzelne Bürstenelemente aus denen die Rotationsbürste zusammengesetzt ist, ausgetauscht werden.Particular advantages arise when only a brush element is provided. This means that the entire rotary brush can be replaced. The replacement is thereby faster than in the case in which the rotary brush must be disassembled and only individual brush elements from which the rotary brush is composed replaced.
Besondere Vorteile ergeben sich, wenn die Rotationsbürste einen insbesondere hohlzylinderförmigen Körper aufweist. Dadurch ist es möglich, die Rotationsbürste auf einer Welle anzuordnen. Der hohlzylinderförmige Körper kann aus Stahl, insbesondere aus Präzisionsstahl gemäß DIN 2391 ausgebildet sein. Ein solcher Körper weist eine besonders dünne Wandung im Bereich von 1 - 5 mm auf und hat eine hohe Genauigkeit, was sich auf den Rundlauf und die Durchbiegung positiv auswirkt. Alternativ ist es denkbar, den Körper aus Kohlefaser oder glasfaserverstärktem Kunststoff herzustellen. Solche Materialien sind allgemein unter den Begriffen CFK und GFK bekannt.Particular advantages arise when the rotary brush has a particular hollow cylindrical body. This makes it possible to arrange the rotary brush on a shaft. The hollow cylindrical body may be formed of steel, in particular of precision steel according to DIN 2391. Such a body has a particularly thin wall in the range of 1 - 5 mm and has a high accuracy, which has a positive effect on the concentricity and the deflection. Alternatively, it is conceivable to make the body of carbon fiber or glass fiber reinforced plastic. Such materials are commonly known by the terms CFK and GFK.
Gemäß einer Ausführungsform kann vorgesehen sein, dass die Borsten des Besatzes in einem Träger gehalten sind, der wendelförmig angeordnet ist. Insbesondere kann der Träger wendelförmig auf dem Körper aufgebracht sein. Dabei kann der Träger auf den Körper aufgeklebt sein.According to one embodiment it can be provided that the bristles of the trimming are held in a carrier which is arranged helically. In particular, the carrier may be helically applied to the body. In this case, the carrier may be glued to the body.
Alternativ ist es denkbar, dass die Borsten des Besatzes büschelartig in Ausnehmungen des Körpers angeordnet sind. Die Büschel können dabei beispielsweise in Bohrungen des Körpers gestanzt werden. Bei dieser Vorgehensweise können jedoch Lücken entstehen, die bei der wendelförmigen Aufwicklung eines Trägers vermieden werden können. In letzterem Fall sind keine Lücken im Besatz. Der Besatz ist einteilig dicht. Dies ist auch ein Vorteil gegenüber Bürstenanordnungen, die aus mehreren Bürstenelementen aufgebaut sind. Dort ist häufig eine Lücke am Stoß zwischen zwei Bürstenelementen zu beobachten.Alternatively, it is conceivable that the bristles of the trimming are tuft-like arranged in recesses of the body. The tufts can be punched, for example, in holes in the body. In this approach, however, gaps may arise that can be avoided in the helical winding of a wearer. In the latter case, there are no gaps in the stocking. The trimming is one-piece tight. This is also an advantage over brush assemblies constructed of multiple brush elements. There is often a gap at the joint between two brush elements to watch.
Besondere Vorteile ergeben sich, wenn in einem oder in den Endbereichen des Bürstenelements härtere und/oder steifere Borsten vorgesehen sind als in dem oder den übrigen Bereichen des Bürstenelements. Härtere oder steifere Borsten haben eine längere Lebensdauer als weichere Borsten. Allerdings ist mit solchen Borsten in der Regel der Nachteil verbunden, dass sie weniger Feuchtigkeit aufnehmen können. Insofern ist es vorteilhaft, auch noch Bereiche vorzusehen, die weichere oder weniger steifere Borsten aufweisen. Beispielsweise können Borsten aus unterschiedlichen Materialien verwendet werden. Um die Verschleißfestigkeit zu erhöhen, können beispielsweise in den äußeren Bereichen des Bürstenelements Borsten aus Polyester oder Polyamid verwendet werden.Particular advantages are obtained if harder and / or stiffer bristles are provided in one or in the end regions of the brush element than in the one or more regions of the brush element. Tougher or stiffer bristles have a longer life than softer bristles. However, such bristles usually have the disadvantage that they can absorb less moisture. In this respect, it is advantageous to provide even areas that have softer or less stiff bristles. For example, bristles made of different materials can be used. To increase the wear resistance, bristles of polyester or polyamide can be used, for example, in the outer regions of the brush element.
Die erfindungsgemäße Rotationsbürste kann zumindest in einem Bereich des Besatzes Borsten mit größerem Durchmesser aufweisen als in einem anderen Bereich. Über den Durchmesser kann die Steifigkeit eingestellt werden.The rotary brush according to the invention can have bristles with a larger diameter at least in one area of the stocking than in another area. The stiffness can be adjusted via the diameter.
Auch die Borstenlänge der Borsten des Bürstenelements kann variiert werden. Beispielsweise können die Borsten zur Mitte des Bürstenelements hin länger werden, sodass eine bauchige Form des Besatzes entsteht. Im Schnitt gesehen kann das Bürstenelement eine konvexe Form aufweisen. Die Borsten können zur Mitte des Bürstenelements hin auch kürzer werden, sodass im (Längs-)Schnitt gesehen eine konkave Form bzw. eine doppelkegelartige Form entsteht. Die Borsten können in einem Mittenbereich auch dieselbe Länge aufweisen und dann zum Ende des Bürstenelements hin, insbesondere linear länger werden, sodass die Enden des Bürstenelements kegelförmig ausgebildet sind.The bristle length of the bristles of the brush element can also be varied. For example, the bristles may become longer toward the center of the brush element, resulting in a bulbous shape of the trim. Seen in section, the brush element may have a convex shape. The bristles can also become shorter toward the center of the brush element, so that when viewed in the (longitudinal) section, a concave shape or a double cone-like shape is created. The bristles may also have the same length in a central region and then become longer towards the end of the brush element, in particular linearly, so that the ends of the brush element are conical.
Weiterhin kann vorgesehen sein, dass die Borsten zumindest in einem Bereich des Besatzes gespleißt sind. Auch unterschiedliche Borstenlängen in unterschiedlichen Bereichen der Rotationsbürste sind denkbar.Furthermore, it can be provided that the bristles are spliced at least in a region of the stocking. Different bristle lengths in different areas of the rotary brush are conceivable.
Gemäß einer Ausführungsform kann in einem Bereich eine Borstenmischung aus unterschiedlichen Borsten vorgesehen sein. Beispielsweise können glatte, d. h. gerade Borsten, und gewellte Borsten gemischt werden, um die Feuchtigkeitsaufnahme des Besatzes in diesem Bereich einzustellen. Es ist jedoch auch denkbar, Borsten aus unterschiedlichen Materialien in einem Bereich des Besatzes zu mischen und dadurch die Eigenschaften des Besatzes einzustellen. Auch dadurch kann die Feuchtigkeitsaufnahme des Besatzes in diesem Bereich eingestellt werden.According to one embodiment, a bristle mixture of different bristles may be provided in one area. For example, smooth, ie straight bristles, and wavy bristles can be mixed to adjust the moisture absorption of the trim in this area. However, it is also conceivable to mix bristles of different materials in a region of the stocking and thereby adjust the properties of the stocking. Also, the moisture absorption of the stocking can be adjusted in this area.
Besondere Vorteile ergeben sich, wenn das Bürstenelement auf einer Welle angeordnet ist. Dabei kann das Bürstenelement entweder indirekt über einen zu reinigenden Druckzylinder angetrieben werden oder die Welle kann antreibbar sein.Particular advantages arise when the brush element is arranged on a shaft. In this case, the brush element can be driven either indirectly via a pressure cylinder to be cleaned or the shaft can be driven.
Gemäß einer Weiterbildung kann vorgesehen sein, dass das Bürstenelement drehfest auf einer antreibbaren Welle angeordnet ist. Dies bedeutet, dass das Bürstenelement selbst in eine Drehung versetzt werden kann, um einen Druckzylinder zu reinigen.According to a development it can be provided that the brush element is arranged rotationally fixed on a drivable shaft. This means that the brush element itself can be rotated to clean a printing cylinder.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung kann vorgesehen sein, dass das Bürstenelement zwischen zwei drehfest auf der Welle anordenbare Ringe oder Scheiben zur drehfesten Anordnung des Bürstenelements auf der Welle angeordnet ist. Dadurch wird sichergestellt, dass sich das Bürstenelement zusammen mit der Welle dreht. Eine besonders zuverlässige drehfeste Verbindung ergibt sich, wenn das Bürstenelement zumindest an einer Stirnseite einen oder mehrere Steigungsabschnitte aufweist, und der zugeordnete Ring oder die Scheibe korrespondierende Steigungsabschnitte aufweist. Insbesondere können die Bürstenelemente an ihren Enden zumindest abschnittsweise helixartig ausgebildet sein. Der Ring oder die Scheibe sind vorzugsweise auf die Kontur des Bürstenelements angepasst, sodass sich eine gute drehfeste Verbindung ergibt. Um die drehfeste Verbindung zu verbessern, können stirnseitig zumindest ein Anschlag, ein Vorsprung oder eine Vertiefung vorgesehen sein, die mit entsprechenden korrespondierenden Konturen der Scheibe oder des Rings zusammenwirken.According to an advantageous embodiment of the invention can be provided that the brush element between two rotatably arranged on the shaft can be arranged rings or discs for non-rotatable arrangement of the brush element on the shaft. This will ensure that the brush element rotates together with the shaft. A particularly reliable rotationally fixed connection results when the brush element has one or more pitch sections at least on one end face, and the associated ring or disk has corresponding pitch sections. In particular, the brush elements can be formed helically at least in sections at their ends. The ring or the disc are preferably adapted to the contour of the brush element, so that there is a good rotational connection. In order to improve the non-rotatable connection, at least one stop, a projection or a recess may be provided on the front side, which cooperate with corresponding corresponding contours of the disc or of the ring.
In den Rahmen der Erfindung fällt außerdem eine Vorrichtung zur Reinigung eines Druckzylinders mit einer erfindungsgemäßen Rotationsbürste, deren Rotationsachse parallel zur Achse des zu reinigenden Druckzylinders angeordnet ist.In the scope of the invention also relates to a device for cleaning a printing cylinder with a rotary brush according to the invention, whose axis of rotation is arranged parallel to the axis of the printing cylinder to be cleaned.
