Definitions
- the invention relates to a suction ring for suction rolls in arms of printing presses for Braking of sheets, wherein arranged over the width of the Bogen affectionweges several suction rings are.
- Suction rolls in arms of printing presses are arranged immediately in front of the delivery pile.
- the suction rings are moved rotationally and they have openings on the surface in the form of slots or holes, which are acted upon by suction.
- the over the suction rings promoted bow is pulled by the suction against the suction rings, slowed down and at the same time tightened.
- the suction roll supports the proper Sheet deposit.
- suction roll is the document DE 33 464 13 A1 removable.
- the suction ring takes according to this publication coaxially on the drive shaft and there are channels and others Air ducts provided over the holes in the surface of the suction ring with Suction air to be applied.
- the suction ring is made in one piece and usually made Metal, preferably made of steel.
- suction ring A disadvantage of this suction ring are the large manufacturing expense for the introduction the air supply into the suction ring and the weight that the suction roll a large Lethargy gives.
- suction rings in practice, which are made in one piece from plastic.
- a disadvantage of this plastic design is the great wear of the working and the Sealing surface, which is provided on the front side of the suction ring.
- the invention is based on the realization of carrying out the suction ring in two pieces.
- the suction ring consists of a metal pot and a core with a lower specific gravity than the pot. By using the injection molding process to produce the core, its production is easy.
- the material used is plastic or aluminum.
- the suction ring By using a material with a great wear resistance for the pot is the wear at the function point of the suction ring (circumferential and sealing surface) low.
- the suction ring Through the use of plastic or aluminum as the core, the suction ring has a total a low weight. However, the suction ring still has the required wear resistance on the functional surfaces.
- Fig. 1 shows the location of the subject invention, a sheet delivery 1 on a printing machine. Shown are the delivery stack 2, the front stops 3 and the suction roller 4. Also recognizable are the boom chain circuit 5, on which the gripper carriages 6 are arranged at constant intervals, and a conveyed sheet 7.
- suction roll 4 includes a plurality of suction rings 8, which have a same structure.
- the individual suction ring 8 (FIGS. 2 and 3) consists of a pot 8.1, which forms the outer functional surfaces (circumference and the face formed as sealing surface 13 for the suction air), and the core 8.2 located in the pot 8.1.
- the pot 8.1 consists of a material - preferably steel - with a high wear resistance.
- the core 8.2 consists of a material with a lower specific gravity than the pot 8.1. As advantageous, the use of plastic has proven to be 8.2 core. However, it is also conceivable to use aluminum as the core 8.2.
- the material of the core 8.2 allows its production by injection or casting. This manufacture lends itself by the shape of the core 8.2 as well.
- the suction ring 8 is provided with a central bore 9.
- the suction ring 8 can also be designed according to the invention, when the suction ring 8 via gear stages is moved rotationally.
- the core 8.2 has on its surface non-continuous recesses 11, which correspond to the radial bores 10 in the peripheral surface and on the sealing surface 13 with the through holes 12.
- bolts are still cast for rotation 15, which are assigned to the bore to prevent rotation in the sealing surface 13 of the pot 8.1.
- About the sealing surface 13 of the suction ring 8 is associated with a vacuum generator, not shown.
- About the through holes 12, the recesses 11 and the radial bores 10 of the sheet 7 is acted upon by suction.
- the suction ring 8 is made by the radial and through-hole 10,12, the bore for twisting security 14 and the central bore 9 is introduced into the pot 8.1.
- the core 8.2 is produced by spraying or casting as described constructively (see Fig. 3). Both parts are joined together, ie, the core 8.2 is pushed into the pot 8.1. It must be ensured by the bore 14 and the bolt 15 (the bore 14 receives the bolt 15) that the radial bores 10 correspond to the recesses 11 and the recesses 11 in turn to the through holes 12. Now, the suction ring 8 is functional and can be assigned to the suction roller 4. Pot 8.1 and core 8.2 are firmly connected.

Description
Die Erfindung geht von der Erkenntnis aus, den Saugring zweistückig auszuführen.
Der Saugring besteht aus einem Topf aus Metall und einem Kern mit geringerem spezifischen Gewicht als der Topf.
Durch die Anwendung des Spritzverfahrens zur Erzeugung des Kernes ist dessen Herstellung einfach. Als Werkstoff kommt Kunststoff oder Aluminium zum Einsatz.

Zur Saugwalze 4 gehören mehrere Saugringe 8, die einen gleichen Aufbau aufweisen. Der einzelne Saugring 8 (Fig. 2 und 3) besteht aus einem Topf 8.1, der die äußeren funktionellen Flächen (Umfang und die als Dichtfläche 13 für die Saugluft ausgebildete Stirnfläche) bildet, und dem im Topf 8.1 befindlichen Kern 8.2.
Der Topf 8.1 besteht aus einem Werkstoff - vorzugsweise aus Stahl - mit einer hohen Verschleißfestigkeit. Der Kern 8.2 besteht aus einem Werkstoff mit einem geringeren spezifischen Gewicht als der Topf 8.1. Als vorteilhaft hat sich die Verwendung von Kunststoff als Kern 8.2 erwiesen. Es ist jedoch auch denkbar, als Kern 8.2 Aluminium einzusetzen. Das Material des Kernes 8.2 ermöglicht seine Herstellung im Spritz- oder Gießverfahren. Diese Herstellung bietet sich durch die Form des Kernes 8.2 außerdem an.
Im Kern 8.2 sind weiterhin Bolzen zur Verdrehsicherung 15 angegossen, die der Bohrung zur Verdrehsicherung in der Dichtfläche 13 des Topfs 8.1 zugeordnet sind.
Über die Dichtfläche 13 ist der Saugring 8 einem nicht dargestellten Sauglufterzeuger zugeordnet. Über die Durchgangsbohrungen 12, die Ausnehmungen 11 und die Radialbohrungen 10 wird der Bogen 7 mit Saugluft beaufschlagt.
Der Saugring 8 wird hergestellt, indem in den Topf 8.1 die Radial- und Durchgangsbohrung 10,12 , die Bohrung zur Verdrehsicherheit 14 sowie die zentrische Bohrung 9 eingebracht wird.
Der Kern 8.2 wird im Spritzverfahren oder im Gießverfahren, wie konstruktiv beschrieben, hergestellt (sh. Fig. 3). Beide Teile werden zusammengefügt, d.h., der Kern 8.2 wird in den Topf 8.1 geschoben. Dabei muss durch die Bohrung 14 und den Bolzen 15 (die Bohrung 14 nimmt den Bolzen 15 auf) gesichert sein, dass die Radialbohrungen 10 zu den Ausnehmungen 11 und die Ausnehmungen 11 wiederum zu den Durchgangsbohrungen 12 korrespondieren. Nunmehr ist der Saugring 8 funktionsfähig und kann zur Saugwalze 4 zugeordnet werden. Topf 8.1 und Kern 8.2 sind dabei fest verbunden.
