The outside case is fitted onto the end pieces in an axial direction by using radial pins (26, 28). A gap between the core and case is filled with an adhering material.

Description

Die Erfindung betrifft eine Tuchspindel für die Aufnahme eines Waschtuches einer Druckzylinder-Waschvorrichtung für Druckmaschinen, mit aufgerauhter Oberfläche der Spindel.The invention relates to a cloth spindle for receiving a wash cloth of a printing cylinder washing device for printing machines, with roughened surface of the spindle.

Druckzylinder von Druckmaschinen, insbesondere der Gummituchzylinder und der Gegendruckzylinder von Offset-Druckmaschinen, müssen von Zeit zu Zeit gereinigt werden. Auf der Oberfläche setzen sich Verunreinigungen ab, die sich insbesondere aus Papierabrieb und Farbresten zusammensetzen. Zu diesem Zweck sind Wasch- oder Reinigungsvorrichtungen bekannt, die eine Reinigung der Oberfläche der Zylinder ermöglichen. Zu diesen gehören neben Reinigungseinrichtungen mit Waschbürsten auch und insbesondere Reinigungsvorrichtungen mit einem Waschtuch, das über die Zylinderoberfläche gezogen wird. Zumeist wird dabei das Tuch mit einer Waschlösung, in der Regel Wasser mit einem Reinigungsmittel, besprüht. Bekannt sind beispielsweise derartige Waschvorrichtungen, bei denen ein Tuchvorrat von einer Vorratsrolle abgezogen, über die Zylinderoberfläche gezogen und auf einer Sammelwelle, die insbesondere auch als Tuchspindel bezeichnet werden kann, nach Erreichen eines vorgegebenen Verschmutzungsgrades gesammelt.Printing cylinders of printing machines, in particular the blanket cylinders and the impression cylinders of offset printing machines, must be cleaned from time to time. On the surface impurities settle, which are composed in particular of paper abrasion and paint residues. For this purpose, washing or cleaning devices are known which allow cleaning of the surface of the cylinder. These include, in addition to cleaning devices with washing brushes and in particular cleaning devices with a washing cloth, which is pulled over the cylinder surface. In most cases, the cloth is sprayed with a washing solution, usually water with a cleaning agent. Such washing devices, for example, are known in which a cloth stock is drawn from a supply roll, pulled over the cylinder surface and collected on a collecting shaft, which can also be referred to as a cloth spindle, after reaching a predetermined degree of contamination.

Diese Tuchspindeln zur Aufnahme des verschmutzten Waschtuches müssen einerseits relativ steif sein, damit sie das Waschtuch gleichmäßig aufrollen können, dürfen aber andererseits auch nicht zu schwer sein, wie es beispielsweise bei Spindeln aus Vollmaterial der Fall ist, da sie in erheblichem Maße zum Gesamtgewicht der Waschvorrichtung beitragen, die unmittelbar in der Druckmaschine gegenüber den zu reinigenden Zylindern gelagert ist und aus einer zurückgezogenen Stellung in eine Betriebsstellung mit Anlage des Waschtuches gegen die Zylinderoberfläche verstellbar, also hin- und hergehend beweglich sein müssen. Diese Beweglichkeit würde durch ein übermäßiges Gewicht der Waschvorrichtung und damit auch der Tuchspindel beeinträchtigt.These cloth spindles for receiving the soiled cloth must on the one hand be relatively stiff so that they can roll up the wash cloth uniformly, but on the other hand must not be too heavy, as is the case, for example, with spindles made of solid material, since they contribute significantly to the total weight of the washing device contribute, which is stored directly in the printing press with respect to the cylinders to be cleaned and adjustable from a retracted position to an operating position with conditioning of the wash cloth against the cylinder surface, so must be reciprocatingly movable. This mobility would be affected by an excessive weight of the washing device and thus also the cloth spindle.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Tuchspindel für eine Waschvorrichtung zu schaffen, die bei geringem Eigengewicht eine hohe Steifigkeit aufweist.The invention is therefore an object of the invention to provide a cloth spindle for a washing device, which has a high stiffness with low weight.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Tuchspindel gekennzeichnet durch eine äußere Hülse aus weichem und leichtem Material und einem Kern aus festem, steifen Material.To solve this problem, the cloth spindle according to the invention is characterized by an outer sleeve of soft and lightweight material and a core of solid, rigid material.

Die erfindungsgemäße Tuchspindel erreicht also optimale Eigenschaften, indem sie nicht als massive Welle ausgebildet ist, sondern aus unterschiedlichen Materialien besteht, die unter Berücksichtigung des Eigengewichts und der gewünschten Funktionen ausgewählt worden sind.The cloth spindle according to the invention thus achieves optimum properties in that it is not formed as a solid shaft, but consists of different materials, which have been selected taking into account the weight and the desired functions.

Vorzugsweise ist der Kern, der aus steifem und festem Material besteht, hohlzylindrisch ausgebildet, da für die Steifigkeit auf diese Weise bei Beschränkung des Gewichts verhältnismäßig die bestmöglichen Wirkungen erreicht werden.Preferably, the core, which is made of rigid and solid material, is formed as a hollow cylinder, since the stiffness in this way is achieved relatively relatively limited weight, the best possible effects.

Der hohlzylindrische Kern ist vorzugsweise an beiden Enden mit Endstücken aus massivem Material verbunden, die der Tatsache Rechnung tragen, dass die Endstücke, mit denen die Tuchspindel in die Waschvorrichtung eingespannt wird, in besonderem Maße mechanischem Verschleiß ausgesetzt sind. Das Material der Endstücke ist deswegen insbesondere auch unter dem Aspekt der Verschleißfestigkeit ausgewählt worden.The hollow cylindrical core is preferably connected at both ends with end pieces made of solid material, which take into account the fact that the end pieces, with which the cloth spindle is clamped in the washing device, are particularly exposed to mechanical wear. The material of the end pieces has therefore been selected especially in terms of wear resistance.

Damit insgesamt ein steifer Verbund entsteht, ist nicht nur der den Kern bildende, hohlzylindrische innere Teil der Spindel, sondern über diesem auch die aus leichterem, weicherem Material bestehende äußere Hülse auf die Endstücke aufgeschoben. Zu diesem Zweck sind auf den Endstücken entsprechende Eindrehungen vorgesehen, und die Sicherung in Längsrichtung erfolgt durch radiale Stifte, die durch den Kern und die Hülse hindurch quer durch die Endstücke verlaufen.So that a total of a rigid composite is formed, not only is the core forming, hollow cylindrical inner part of the spindle, but over this also made of lighter, softer material outer sleeve pushed onto the end pieces. For this purpose, corresponding grooves are provided on the end pieces, and the securing in the longitudinal direction by radial pins which extend through the core and the sleeve through the end pieces.

Die Hülse kann beispielsweise aus Aluminium oder Aluminumlegierungen bestehen. Sie ist verhältnismäßig weich, da hier eine Riffelung oder Rändelung angebracht werden muß. Die Endstücke bestehen vorzugsweise aus nicht rostendem Stahl, während der Kern aus einem insbesondere unter dem Gesichtspunkt der Steifigkeit ausgewählten Material, z. B. Stahl besteht.The sleeve may for example consist of aluminum or aluminum alloys. It is relatively soft, since here a corrugation or knurling must be attached ß. The end pieces are preferably made of stainless steel, while the core of a particular selected from the viewpoint of rigidity material, eg. B. steel.

In einem der Endstücke kann ein federnd abgestütztes Innenteil vorgesehen sein, das geeignet ist, Ungenauigkeiten der Waschvorrichtung bei der Aufnahme der Spindel auszugleichen.In one of the end pieces may be provided a resiliently supported inner part, which is suitable for compensating for inaccuracies of the washing device when receiving the spindle.

Im folgenden werden bevorzugte Ausführungsbeispiele der Erfindung anhand der beigefügten Zeichnung näher erläutert.In the following preferred embodiments of the invention will be described with reference to the accompanying drawings.

Die einzige Figur zeigt einen Längsschnitt durch eine erfindungsgemäße Tuchspindel.The single FIGURE shows a longitudinal section through a cloth spindle according to the invention.

In der Zeichnung ist die erfindungsgemäße Tuchspindel verkleinert dargestellt. Sie ist im übrigen aus Platzgründen unterbrochen gezeigt, da sie im Verhältnis zum Durchmesser eine beträchtliche Länge aufweist. Die Proportionen und die Maße der Zeichnung sind nicht bindend.In the drawing, the cloth spindle according to the invention is shown reduced in size. It is shown otherwise interrupted for reasons of space, since it has a considerable length in relation to the diameter. The proportions and dimensions of the drawing are not binding.

Die erfindungsgemäße Tuchspindel ist mehrteilig und setzt sich aus mehreren Komponenten aus unterschiedlichen Materialien zusammen.The cloth spindle according to the invention is multi-part and is composed of several components of different materials.

Die tragende Struktur der Tuchspindel setzt sich zusammen aus zwei Endstücken 10,12 und einem rohrförmigen Kern 14, der die Endstücke 10,12 verbindet und mit diesen verbunden ist. An den beiden einander zugewandten inneren Enden der Endstücke sind Eindrehungen 16,18 vorgesehen, so dass die Endstücke hier einen verringerten Durchmesser aufweisen und der Kern 14 auf die Endstücke 10,12 aufgeschoben werden kann.The supporting structure of the cloth spindle is composed of two end pieces 10,12 and a tubular core 14 which connects the end pieces 10,12 and is connected thereto. Recesses 16, 18 are provided at the two mutually facing inner ends of the end pieces, so that the end pieces here have a reduced diameter and the core 14 can be pushed onto the end pieces 10, 12.

Die Endstücke 10,12 bestehen vorzugsweise aus einem verschleißfesten, nicht korrodierenden Material, beispielsweise nicht rostendem Stahl. Die Verschleißfestigkeit ist hier deshalb wichtig, weil die Endstücke beim wiederholten Ein- und Ausspannen erheblich strapaziert werden.The end pieces 10,12 are preferably made of a wear-resistant, non-corrosive material, such as stainless steel. The wear resistance is important here because the end pieces are significantly strained during repeated clamping and unclamping.

Außen ist der rohrförmige Kern 14 durch eine Hülse 20 umgeben, die vorzugsweise aus einem leichten und relativ weichen Material besteht, so dass die Hülse ein relativ geringes Gewicht aufweist und leicht in ihrer Oberfläche zu bearbeiten ist. Auf der Außenfläche der Hülse 20 läßt sich also mit relativ geringem Aufwand eine Rändelung oder Riffelung herstellen, die für die Aufnahme des Waschtuches benötigt wird.Externally, the tubular core 14 is surrounded by a sleeve 20, which is preferably made of a light and relatively soft material, so that the sleeve has a relatively low weight and is easy to machine in its surface. On the outer surface of the sleeve 20 can thus be produced with relatively little effort knurling or corrugation, which is required for receiving the wash cloth.

Die Hülse 20 wird ebenfalls über die Endstücke 10,12 geschoben, die auch zu diesem Zweck Eindrehungen aufweisen, die mit 22,24 bezeichnet sind. Diese Eindrehungen 22,24 sind zweistufig ausgebildet, da zum Ende der Hülse 20 hin deren Innendurchmesser an beiden Enden stufenförmig vergrößert wird. Zumindest mit diesem letzten Abschnitt der Hülse ragt die Hülse 20 über den Kern 14 hinaus. Die Hülse 20 bildet somit die äußere Oberfläche der Gesamtanordnung bis nahezu zu den Enden der beiden Endstücke 10,12. Die Hülse 20 bestimmt die nutzbare Breite der Tuchspindel insgesamt.The sleeve 20 is also pushed over the end pieces 10,12, which also have for this purpose grooves, which are designated 22,24. These grooves 22,24 are formed in two stages, since the end of the sleeve 20 toward the inner diameter is increased stepwise at both ends. At least with this last section of the sleeve, the sleeve 20 projects beyond the core 14. The sleeve 20 thus forms the outer surface of the overall assembly almost to the ends of the two end pieces 10,12. The sleeve 20 determines the usable width of the cloth spindle as a whole.

Zur axialen Festlegung der Hülse 20 und auch des Kerns 14 in bezug auf die Endstücke und der Hülse und des Kerns zueinander sind radiale Stifte 26,28 vorgesehen. Diese Stifte können in das Material der Endstücke 10,12 eingeschraubt oder eingeschlagen werden. Wenn sie eingeschraubt sind, hat dies den Vorteil, dass die Gesamtanordnung leicht demontierbar ist. Die Stifte schließen in ihrer Länge bündig mit der Außenfläche der Hülse 20 ab.For axial fixing of the sleeve 20 and also of the core 14 with respect to the end pieces and the sleeve and the core to each other radial pins 26,28 are provided. These pins can be screwed or hammered into the material of the end pieces 10,12. When they are screwed in, this has the advantage that the overall arrangement is easy to disassemble. The pins terminate in their length flush with the outer surface of the sleeve 20.

Das linke Endstück in der Zeichnung, das mit 10 bezeichnet ist, weist insoweit eine Besonderheit auf, als sich im Inneren des Endstücks ein federnd nach außen vorgespannter Befestigungszapfen 30 befindet. Dieser Befestigungszapfen ist verschiebbar in einer axialen Bohrung 32 angeordnet, die koaxial von außen in das Endstück 10 eintritt. Diese Bohrung 32 nimmt an ihrem inneren Ende eine Druckfeder 34 auf, die bestrebt ist, den Befestigungszapfen 30 nach außen, zum Ende der Tuchspindel zu drücken. Im übrigen befindet sich in dem Befestigungszapfen 30 ein Langloch 36, in dem ein radialer, in das Endstück eingesetzter Stift 38 liegt, der die äußere Endstellung des Befestigungszapfens 30 bestimmt.The left-hand end piece in the drawing, which is designated by 10, has a special feature insofar as there is a spring-outwardly prestressed fastening pin 30 inside the end piece. This mounting pin is slidably disposed in an axial bore 32 which enters coaxially from the outside into the end piece 10. This bore 32 receives at its inner end a compression spring 34, which tends to push the mounting pin 30 outwardly to the end of the cloth spindle. Moreover, in the mounting pin 30 is a slot 36 in which a radial, inserted into the end pin 38, which determines the outer end position of the mounting pin 30.

Außerhalb des Endstücks weist der Befestigungszapfen 30 einen Einspannkopf 40 auf, während auf dem äußeren Ende des anderen Endstücks 12 dieses Endstück selbst zu einem Einspannzapfen 42 geringeren Durchmessers verjüngt ist. Der federnd abgestützte Befestigungszapfen ermöglicht einen Toleranzausgleich hinsichtlich der Abmessungen der Aufnahmeeinrichtung der Waschvorrichtung, die hier nicht behandelt wird.Outside of the end piece, the fastening pin 30 has a clamping head 40, while on the outer end of the other end piece 12, this end piece itself tapers to a clamping pin 42 of smaller diameter. The resiliently supported mounting pin allows a tolerance compensation with respect to the dimensions of the receiving device of the washing device, which is not treated here.

Eine weitere Optimierung der Steifigkeit könnte darin bestehen, den Zwischenraum zwischen Kern 14 und Hülse 20 mit einem speziellen Material aufzufüllen. Damit kann man eine Durchbiegung der Hülse 20 zum Kern 14 verhindern. Dies wäre beispielsweise durch Ausschäumen zu bewerkstelligen.Further optimization of rigidity could be to fill the gap between core 14 and sleeve 20 with a special material. This can prevent a bending of the sleeve 20 to the core 14. This would be done, for example, by foaming.
