Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Fördern eines Bogens nach dem Oberbegriff des Anspruchs 1.The The invention relates to a device for conveying a sheet after Preamble of claim 1.
Bei Bogendruckmaschinen ist es bekannt, Saugluft- und/oder Blasluftvorrichtungen vorzusehen, die eine Kraftwirkung auf einen Bogen ausüben, während der Bogen an seiner Vorderkante in Greifern gehalten ist und entlang einer Förderbahn bewegt wird. Dabei wird ein Tragluftpolster erzeugt, so dass der Bogen nicht mit einem Leitblech in Berührung kommt, welches entlang der Förderbahn angeordnet ist. Das Tragluftpolster wird mit Düsen erzeugt, die im Leitblech ausgebildet sind. Es ist bekannt, in einem Leitblech eine Vielzahl von in einem Raster angeordneten Düsen vorzusehen, aus denen Blasluft in einer bevorzugten Richtung austritt. Die Zahl, Anordnung und Geometrie der Düsen ist so gewählt, dass sich ein möglichst ruhiger Bogenlauf ergibt.at Sheet-fed presses, it is known Saugluft- and / or blown air devices provide that exert a force on a bow, during the Arch is held in its gripper at its front edge and along a conveyor belt is moved. In this case, a supporting air cushion is generated, so that the Bow does not come into contact with a baffle, which along the conveyor belt is arranged. The carrying air cushion is generated with nozzles in the baffle are formed. It is known in a baffle a variety to provide arranged in a grid nozzles from which blowing air exits in a preferred direction. The number, arrangement and Geometry of the nozzles is chosen that one as possible quiet sheet run results.

Nachteilig bei den Lösungen nach dem Stand der Technik ist, dass die Luftströmung senkrecht zur Bogenoberfläche relativ zur Strömung in Förderrichtung eines Bogens zu groß ist, so dass Instabilitäten auftreten.adversely in the solutions According to the prior art, the air flow is perpendicular to the sheet surface relative to the flow in the conveying direction a bow is too big, causing instabilities occur.
Aufgabe der Erfindung ist es, eine Vorrichtung zum Fördern eines Bogens zu entwickeln, bei der ein strömungsdynamisches Tragluftpolster verwendet wird, welches verbesserte Trageigenschaften für den Bogen aufweist.task the invention is to develop a device for conveying a bow, in the case of a fluid dynamic Tragluftpolster is used, which improved carrying properties for the bow having.
Die Aufgabe wird mit einer Vorrichtung gelöst, welche die Merkmale nach Anspruch 1 aufweist. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The The object is achieved with a device which the features Claim 1. Advantageous embodiments emerge the dependent claims.
Gemäß der Erfindung besteht die Vorrichtung aus einer Vielzahl von Strömungsmittelauslässen, denen jeweils ein Strömungskanal vorgeordnet ist, wobei das Strömungsmittel gerichtet vorzugsweise im Wesentlichen parallel zur Förderbahn eines Bogens ausströmt. Das Strömungsmittel wird jeweils in Strömungskanal beschleunigt. Die Strömungsmittelauslässe bilden eine Leiteinrichtung für den im Kanal erzeugten Strömungsmittelstrahl. Die senkrecht zur Förderbahn vorhandene Komponente des Strömungsmittels ist praktisch auf ein Minimum reduziert.According to the invention, the device consists of a plurality of fluid outlets sen, which in each case a flow channel is arranged upstream, wherein the fluid directed directed preferably flows substantially parallel to the conveying path of an arc. The fluid is accelerated in each case in the flow channel. The fluid outlets form a guide for the fluid jet generated in the channel. The component of the fluid present perpendicular to the conveyor track is practically reduced to a minimum.
Es ist vorteilhaft, wenn die Auslässe in einem Leitblech angeordnet sind, wobei als Strömungsmittel Luft verwendet wird. Die Auslässe können durch Abbiegen von im Leitblech ausgeschnittenen Zungen gebildet sein, wobei die Biegelinien vorzugsweise senkrecht zur Förderrichtung liegen. Die Strömungskanäle leiten die ausströmende Luft in Förderrichtung oder schräg zur Förderrichtung. In einer Ausführungsform sind die Strömungskanäle mittels eines Bauteils gebildet, welches eine oder mehrere Zungen bzw. Auslässe strömungstechnisch umschließt. Die Strömungskanäle stehen mit einer steuerbaren Blaslufteinrichtung in Verbindung. Die Querschnittsflächen der Strömungskanäle sind jeweils kleiner als oder gleich der Querschnittsfläche eines Auslasses. Fertigungstechnisch vorteilhaft ist es, wenn ein Strömungskanal einen rechteckförmigen Querschnitt aufweist, wobei die Kanallänge größer als 2/3 des Maximums aus Querschnittshöhe und Querschnittsbreite ist.It is beneficial if the outlets are arranged in a baffle, wherein as a fluid Air is used. The outlets can formed by bending of cut in the baffle tongues be, with the bending lines preferably perpendicular to the conveying direction lie. Lead the flow channels the outflowing Air in the conveying direction or aslant to the conveying direction. In one embodiment are the flow channels by means of a component formed which one or more tongues or outlets fluidly encloses. The flow channels are with a controllable Blaslufteinrichtung in conjunction. The cross-sectional areas of Flow channels are each less than or equal to the cross-sectional area of a Outlet. From a manufacturing point of view, it is advantageous if a flow channel a rectangular one Cross section, wherein the channel length is greater than 2/3 of the maximum Section height and section width.
Die Erfindung ist bei Bogendruckmaschinen, insbesondere beim Fördern von Bogen zwischen Druckwerken und beim Fördern von Bogen von einem letzten Druckwerk auf einen Auslegerstapel, anwendbar.The The invention is in sheet-fed presses, especially in conveying Sheet between printing units and conveying sheets from a last one Printing unit on a delivery pile, applicable.
