The raised part fixed to the outer surface of the conveyor drum is made of springy elastic support material (6) to which filament like support elements (7) are fixed. An ink-repellent material (10) such as a small quantity of chromium, is attached to the outer ends of the support elements.

Description

Die Erfindung bezieht sich auf eine Transporttrommel in Rotationsdruckmaschinen mit einem Aufzug zum Verhindern des Abschmierens eines frischen Druckproduktes beim Transport desselben durch die Maschine, wobei der Aufzug auf der Mantelfläche der Transporttrommel befestigt ist und aus einem Trägermaterial mit darin befestigten fadenförmigen Stützelementen besteht.The invention relates to a transport drum in rotary printing machines with an elevator to prevent smearing of a fresh printed product when transporting it through the machine, the elevator on the Shell surface of the transport drum is attached and made of a carrier material there is attached thread-like support elements.

Aus der DE 14 71 728 B ist eine Leit- oder Gegendruckwalze bekannt, die einen derartigen Aufzug aufweist, wobei bei der bekannten Ausführung die fadenförmigen Stützelemente senkrecht von dem Aufzug abstehen und aus einem flexiblem Polyamid ausgeführt sind. Es hat sich gezeigt, daß diese spitzen fadenförmigen Stützelemente sich in die frische Druckfarbe eingraben können und hier zu einer Beschädigung der Oberfläche führen. Auch können Farbpartikel entnommen werden, die sich in anderen Bereichen des Druckbildes störend absetzten. Die als Alternative in der bekannten Druckschrift aufgezeigte Ausgestaltung der Stützelemente als Schlaufen, erfordert jedoch einen höheren Herstellungsaufwand, insbesondere wenn die einzelenen Schlaufen eine gleiche Höhe zur Trommelmantelfläche aufweisen sollen.From DE 14 71 728 B a guide or counter pressure roller is known, the one has such elevator, the thread-like in the known embodiment Support elements protrude vertically from the elevator and from a flexible Are made of polyamide. It has been shown that these pointed filiform Support elements can dig into the fresh printing ink and become one Damage to the surface. Color particles can also be removed that are distracting in other areas of the printed image. As Alternative embodiment shown in the known publication Support elements as loops, but requires a higher manufacturing effort, especially if the individual loops are at the same height Should have drum surface.

Bei einer anderen bekannten Ausführung eines Aufzugs auf einer Transporttrommel (EP 0 036 937 B1) wird ein Körperstoff verwendet, der die frisch bedruckten Druckprodukte trägt. Auch bei dieser Ausgestaltung läßt sich eine Farbannahme des Aufzuges nicht ausschließen, so daß in gewissen Abständen eine Reinigung des Aufzuges erforderlich ist. Geschieht die Reinigung in der Maschine, so kann durch die abgerubbelten Farbreste ein Verschmutzen anderer Maschinenteile verursacht werden, die zu Druckstörungen führen können. In another known version of an elevator on a Transport drum (EP 0 036 937 B1), a body material is used, the fresh printed printed products. In this embodiment, too Color exclusion of the elevator does not rule out, so that at certain intervals Cleaning the elevator is required. If the cleaning is done in the machine, so the rubbed off paint residues can contaminate others Cause machine parts that can lead to pressure disturbances.

Ausgehend von diesem Stand der Technik ist es die Aufgabe vorliegender Erfindung ein Abschmieren bzw. Absetzten von Farbpartikeln auf den Stützelementen des Aufzugs weitgehend zu verhindern, um eine Beeinträchtigung des frischen Druckbildes auf dem Druckprodukt zu vermeiden.Starting from this prior art, it is the object of the present invention a smearing or settling of color particles on the support elements of the To prevent elevator largely to affect the fresh Avoid the printed image on the printed product.

Gemäß der Erfindung wird die Aufgabe dadurch gelöst, daß die Stützelemente federnd ausgebildet sind und daß an den äußeren Enden der Stützelemente ein farbabweisendes Material aufgebracht ist. Durch die federnde Ausbildung der Stützelemente können diese einer Relativbewegung des Druckproduktes auf der Transporttrommel folgen, ohne daß eine Bewegung zwischen diesen und dem Druckprodukt selbst stattfindet. Nachdem das Druckprodukt die Transporttrommel verlassen hat, federn die einzelnen Stützelemente wieder in ihre Ausgangsposition zurück. Durch das Aufbringen eines farbabweisenden Materials auf die äußeren Enden der Stützelemente wird eine Übernahme von Farbpartikeln verhindert und somit auch eine Beschädigung des Druckbildes. Außerdem wird hierdurch die Auflagefläche für das Druckprodukt vergrößert, so daß ein Eindringen der Stützelemente in die Druckfarbe ebenfalls verhindert wird. Trotzdem werden aber sehr kleine Auflagepunkte für das Druckprodukt geschaffen, so daß ein beschädigungsfreier Transport desselben gewährleistet ist.According to the invention the object is achieved in that the support elements are resilient and that at the outer ends of the support elements paint-repellent material is applied. Due to the resilient training of Support elements can be a relative movement of the printed product on the Follow the transport drum without any movement between them and the Print product itself takes place. After the printed product the transport drum has left, the individual support elements spring back to their starting position back. By applying a color-repellent material to the outer The end of the support elements prevents the transfer of color particles and thus damage to the printed image. It also makes the Support area for the printed product enlarged, so that penetration of the Support elements in the printing ink is also prevented. Still will created very small support points for the printed product, so that a damage-free transport of the same is guaranteed.

In einer vorteilhaften Ausgestaltung der Erfindung ist an den äußeren Enden der Stützelemente eine geringe Menge Chrom aufgebracht. Bei Chrom handelt es sich um ein farbabweisendes Material, was den zusätzlichen Vorteil hat, daß die Stützelemente eine hohe Verschleißfestigkeit aufweisen.In an advantageous embodiment of the invention, the Support elements applied a small amount of chrome. Chrome is a color-repellent material, which has the additional advantage that the Support elements have a high wear resistance.

In einer weiteren vorteilhatten Ausgestaltung der Erfindung sind die Stützelemente schräg im Trägermaterial angebracht, so daß je nach Material der Stützelemente eine hohe Federung derselben erreicht wird. In a further advantageous embodiment of the invention, the support elements attached obliquely in the carrier material, so that depending on the material of the support elements a high suspension of the same is achieved.

Eine weitere vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß die Stützelemente radial zur Transporttrommel federnd ausgebildet sind. Die federnde Ausbildung kann z. B. in Schleifenform oder in Spiralform der Stützelemente ausgeführt sein. Weiterhin kann durch eine federelastische Ausbildung des Trägermaterials die Federwirkung der Stützelemente verbessert werden, so daß auch ein relativ steifes Material für die Stützelemente Verwendung finden kann. Auch hierdurch können die Stützelemente nicht nur in Umfangs- und Längsrichtung der Transporttrommel, sondern auch in radialer Richtung federn, so daß die Abwicklung der Transporttrommeln verbessert und ein Abschmieren der Druckprodukte mit Sicherheit verhindert wird.A further advantageous embodiment of the invention is characterized in that that the support elements are designed to be resilient radially to the transport drum. The resilient training can e.g. B. in loop form or in spiral form Supporting elements can be executed. Furthermore, by a resilient Training of the carrier material improves the spring action of the support elements be, so that a relatively stiff material for the support elements use Can be found. This also allows the support elements not only in circumferential and Longitudinal direction of the transport drum, but also in the radial direction, so that improves the handling of the transport drums and lubrication of the Print products are prevented with certainty.

Bei dem in Fig. 1 dargestellten Schema einer Rotationsdruckmaschine wird das Druckprodukt von einem Druckzylinder 1 über drei Transporttrommeln 2, 3, 4 einem nächsten Druckzylinder 5 übergeben. Das mit einer Farbe bedruckte Druckprodukt gelangt von dem Druckzylinder 1 auf die Transporttrommel 2 und liegt hier mit der frischen Farbe nach innen auf dieser Transporttrommel auf. Danach wird es auf die Transporttrommel 3 übergeführt, so daß die frische Druckfarbe außen zu liegen kommt und gelangt dann auf die Transporttrommel 4 ebenfalls mit innenliegender frischer Druckfarbe. Von dieser wird das Druckprodukt an den nächsten Druckzylinder 5 übergehen und erhält hier die nächst Farbe aufgedruckt. Somit ist auf den Transporttrommeln 2 und 4 ein Aufzug zum Verhindern des Abschmierens der frischen Druckfarbe beim Transport der Druckprodukte durch die Maschine erforderlich. Der Aufzug wird auf der Mantelfläche der Transporttrommel befestigt und besteht aus einem Trägermaterial 6 mit darin befestigten flexiblen fadenförmigen Stützelementen 7, 8, 9.In the scheme of a rotary printing press shown in FIG Print product from a printing cylinder 1 via three transport drums 2, 3, 4 one hand over the next printing cylinder 5. The printed product with one color passes from the impression cylinder 1 to the transport drum 2 and lies here with the fresh paint inside on this transport drum. After that it gets on the Transport drum 3 transferred so that the fresh printing ink to be outside comes and then arrives at the transport drum 4 also with an internal one fresh ink. From this the printed product is transferred to the next one Pass over cylinder 5 and get the next color printed here. So is on the transport drums 2 and 4 an elevator to prevent greasing the fresh ink when the print products are transported through the machine required. The elevator is attached to the outer surface of the transport drum and consists of a carrier material 6 with flexible thread-shaped fastened therein Support elements 7, 8, 9.
