Description

Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Luftdrossel, wobei Lochplatten zusammengefügt werden, nach dem Oberbegriff des Anspruchs 1.The present invention relates to a method for producing an air throttle, wherein perforated plates are joined, according to the preamble of claim 1.

In DE 44 06 739 A1 ist eine Luftdrossel ohne nähere Angaben zu deren Herstellung beschrieben.In DE 44 06 739 A1 an air throttle is described without further details for their preparation.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung der Luftdrossel in großen Stückzahlen anzugeben, bei welchem auch eine optimale Drosselwirkung gewährleistet ist.The invention has for its object to provide a method for producing the air throttle in large numbers, in which an optimal throttle effect is ensured.

Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 gelöst. Das erfindungsgemäße Verfahren zur Herstellung einer Luftdrossel, wobei Lochplatten zusammengefügt werden, ist dadurch gekennzeichnet, dass unter Verwendung mindestens einer flüssigen oder klebrigen Substanz die Lochplatten miteinander verbunden werden und die Luftdrossel abgedichtet wird. Dabei kann die Substanz zum Verbinden der Lochplatten und/oder zum Abdichten der Luftdrossel verwendet werden.This object is achieved by a method having the features of claim 1. The inventive method for producing an air throttle, wherein perforated plates are joined together, is characterized in that using at least one liquid or sticky substance, the perforated plates are joined together and the air throttle is sealed. In this case, the substance can be used for connecting the perforated plates and / or for sealing the air throttle.

Eine Weiterbildung des erfindungsgemäßen Verfahrens beinhaltet, dass die Lochplatten miteinander verlötet werden und die Substanz verflüssigtes Lotmaterial ist. Hierbei dient das Lotmaterial sowohl zum Verbinden der Lochplatten als auch zum Abdichten der Luftdrossel.A further development of the method according to the invention involves soldering the perforated plates together and the substance being liquefied solder material. Here, the solder material serves both for connecting the perforated plates and for sealing the air throttle.

Bei einer weiteren Weiterbildung werden die Lochplatten miteinander verklebt und ist die Substanz ein Klebstoff. Dabei kann der Klebstoff in Kapseln enthalten sein und durch ein zwischen den Lochplatten erfolgendes Aufplatzen der Kapseln freigesetzt werden. Stattdessen kann der Klebstoff auch beidseitig auf einer Klebefolie enthalten sein und kann die Klebefolie zwischen die Lochplatten eingefügt werden. In beiden Fällen dient die Substanz, also der Klebstoff, nicht nur zum Verbinden der Lochplatten miteinander, sondern auch zum Abdichten der Luftdrossel.In a further development, the perforated plates are glued together and the substance is an adhesive. The adhesive may be contained in capsules and released by a bursting of the capsules between the perforated plates. Instead, the adhesive may also be contained on both sides of an adhesive film and the adhesive film may be inserted between the perforated plates. In both cases, the Substance, so the adhesive, not only for connecting the perforated plates together, but also for sealing the air throttle.

Gemäß einer weiteren Weiterbildung ist die Substanz eine Flüssigkeit, in der sich Partikel zur Fugen-Abdichtung befinden. Hierbei dient die partikelhaltige Flüssigkeit ausschließlich zur Abdichtung der Luftdrossel und können die Lochplatten mittels des Klebstoffs in den Kapseln oder auf der Klebefolie oder mittels des Lotmaterials oder mittels Verschraubungen miteinander verbunden werden.According to a further development, the substance is a liquid in which there are particles for joint sealing. Here, the particle-containing liquid is used exclusively for sealing the air throttle and the perforated plates can be connected to each other by means of the adhesive in the capsules or on the adhesive film or by means of the solder material or by means of screwing.

Bei einer weiteren Weiterbildung weist mindestens eine der Lochplatten zwischen Löchern Stege mit einer weniger als 1,0 Millimeter betragenden Stegbreite auf. Die Stegbreite beträgt vorzugsweise weniger als 0,5 Millimeter. Dadurch lässt sich ein sehr filigran in Wirbelkammern gegliederter Innenraum der Luftdrossel herstellen, der ebenso wie deren Abdichtung für eine optimale Drosselwirkung von Bedeutung ist.In a further development, at least one of the perforated plates between holes webs with less than 1.0 millimeters amount web width. The web width is preferably less than 0.5 millimeters. As a result, it is possible to produce an interior of the air throttle which is very finely structured in swirl chambers and, like its sealing, is of importance for an optimal throttling effect.

Zur Erfindung gehört auch eine Bogenbremse zum Bremsen von Bogen aus Bedruckstoff, welche Bogenbremse mindestens eine Luftdrossel umfasst, die nach dem erfindungsgemäßen oder einer seiner Weiterbildungen entsprechenden Verfahren hergestellt ist. Des Weiteren gehören zur Erfindung auch ein Bogenausleger, der mit besagter Bogenbremse ausgestattet ist, und eine Maschine zur Verarbeitung der Bogen aus Bedruckstoff, die den Bogenausleger umfasst. Besagte Maschine ist vorzugsweise eine Druckmaschine.The invention also includes a sheet brake for braking sheets of printing material, which sheet brake comprises at least one air throttle, which is produced by the method according to the invention or one of its developments. Furthermore, the invention also includes a sheet delivery, which is equipped with said sheet brake, and a machine for processing the sheets of substrate, which comprises the sheet delivery. Said machine is preferably a printing press.

The second perforated plate 2 is arranged between the first perforated plates 1 to form a plate pack, which in turn is arranged between the third and fourth perforated plates 3, 4. In this case, the second, third and fourth perforated plate 2, 3, 4 in the solder material still free state.

Figur 4 zeigt einen folgenden Verfahrensschritt, bei dem sämtliche aufeinander gestapelte und gepresste Lochplatten 1 bis 4 mitsamt der Positioniervorrichtung 10 in einen Lötofen 14 gesetzt sind bzw. durch letzteren hindurchfahren, welcher Lötofen 14 den Lotfilm auf den ersten Lochplatten 1 wieder verflüssigt, so dass sich dieser Lotfilm mit der zweiten, dritten und vierten Lochplatte 2, 3, 4 verbindet.FIG. 4 shows a following method step, in which all stacked and pressed perforated plates 1 to 4 together with the positioning device 10 are placed in a soldering oven 14 or pass through the latter, which soldering oven 14 liquefies the solder film on the first perforated plates 1 again, so that this solder film with the second, third and fourth perforated plate 2, 3, 4 connects.

Figur 5 zeigt die Lochplatten 1 bis 4 in nach erneuter Aushärtung des Lotfilms fest miteinander verlötetem Zustand, wobei die Lochplatten 1 bis 4 bereits aus dem Lötofen 14 und der Positioniervorrichtung 10 entnommen sind. In diesem Zustand sind die Stege 9 der ersten Lochplatten 1 mit zwischen den großen Löchern 6 der zweiten Lochplatte 2 vorhandenen Stegen und mit der dritten und vierten Lochplatte 3, 4 über gas- bzw. luftdichte Lötverbindungen 15 miteinander verbunden. Bei der daraus resultierenden Luftdrossel 16 werden von jedem großen Loch 16 mehrere kleine Löcher 5 überdeckt, so dass sich ein im Wesentlichen mäanderförmiger Strömungsweg 17 der Blasluft mit Luftverwirbelungen in Wirbelkammern 18 der innenseitig labyrinthartig ausgebildeten Luftdrossel 16 ergibt.Figure 5 shows the perforated plates 1 to 4 in after renewed hardening of the solder film firmly soldered together state, the perforated plates 1 to 4 are already removed from the soldering oven 14 and the positioning device 10. In this state, the webs 9 are the first perforated plates 1 with webs present between the large holes 6 of the second perforated plate 2 and with the third and fourth perforated plates 3, 4 via gas or airtight solder joints 15 connected to each other. In the resulting air throttle 16 several small holes 5 are covered by each large hole 16, so that a substantially meandering flow path 17 of the blowing air with air turbulence in vortex chambers 18 of the inside labyrinth-shaped air throttle 16 results.

Figur 6 zeigt die im Zusammenhang mit Figur 1a bereits beschriebenen Lochplatten 1, 2 als Ausgangsmaterialien für ein zum Löten alternatives Verbindungsverfahren. Bei diesem Verbindungsverfahren können die Lochplatten 1, 2 nicht nur aus Metall, sondern stattdessen auch aus einem Kunststoff oder einem anderen nicht-metallischen Material bestehen. Mittels einer Streuvorrichtung 19 werden mit Klebstoff gefüllte Kapseln 20 zwischen die zweite Lochplatte 2 und die ersten Lochplatten 1 eingebracht.FIG. 6 shows the perforated plates 1, 2 already described in connection with FIG. 1a as starting materials for an alternative bonding method for soldering. In this connection method, the perforated plates 1, 2 can not only be made of metal, but instead also of a plastic or other non-metallic material. By means of a spreading device 19 capsules 20 filled with adhesive are introduced between the second perforated plate 2 and the first perforated plates 1.

Figur 7 zeigt, dass nach einem pressungslosen Aufeinanderstapeln der Lochplatten 1, 2 die Kapseln 20 in jedem Plattenbereich noch inaktivierte Klebstoffschichten 21 bilden. Noch keine der Kapseln 20 ist aufgeplatzt und hat ihren Klebstoff freigesetzt.FIG. 7 shows that after a squeeze-free stacking of the perforated plates 1, 2, the capsules 20 still form inactivated adhesive layers 21 in each plate region. None of the capsules 20 has burst yet and released their glue.

Figur 8 zeigt, dass danach das aus den Lochplatten 1, 2 und inaktivierten Klebstoffschichten 21 gebildete Plattenpaket in die Positioniervorrichtung 10 eingesetzt wird, um das filigrane Lochmuster der ersten Lochplatten 1 relativ zu dem etwas weniger filigranen Lochmuster der zweiten Lochplatte 2 exakt auszurichten.FIG. 8 shows that thereafter the plate pack formed from the perforated plates 1, 2 and inactivated adhesive layers 21 is inserted into the positioning device 10 in order to precisely align the filigree hole pattern of the first perforated plates 1 relative to the slightly less filigree perforated pattern of the second perforated plate 2.

Figur 9 zeigt, dass in einem folgenden Schritt das Plattenpaket innerhalb der Positioniervorrichtung 10 mit einer Kraft F (und Gegenkraft) beaufschlagt wird, wobei nur diejenigen Kapseln 20 zum Aufplatzen und dadurch zum Freisetzen des Klebstoffs gebracht werden, die sich außerhalb des Bereichs der kleinen und großen Löcher 5, 6 und somit zwischen aufeinander gepressten Plattenflächen befinden. Nur die danach zerplatzten Kapseln 22 sind einem beidseitigen Plattendruck ausgesetzt gewesen und setzen ihren Klebstoff frei.FIG. 9 shows that in a following step, the plate package within the positioning device 10 is subjected to a force F (and counterforce), whereby only those capsules 20 are brought to burst and thereby release the adhesive which extends outside the region of the small and large holes 5, 6 and thus between pressed plate surfaces are located. Only the subsequently burst capsules 22 have been exposed to a two-sided plate pressure and release their adhesive.

Figur 10 zeigt, dass im Ergebnis die Lochplatten 1, 2 durch aktivierte Klebstoffschichten 23, die der Klebstoff aus den zerplatzten Kapseln 22 bildet, fest miteinander verklebt und abgedichtet sind, und die restlichen, unzerplatzten Kapseln 24 mittels eines gasförmigen (z. B. Druckluft) oder flüssigen (z. B. Wasser) Fluids 25 durch die Löcher 5, 6 hindurch aus dem Plattenverbund herausgeblasen oder -gespült werden. Zeichnerisch nicht dargestellt ist, dass der aus den inneren Lochplatten 1, 2 bestehende Plattenverbund mit den äußeren Lochplatten 3, 4 (vgl. Figur 3) ebenso mittels der Kapseln 20 zur fertigen Luftdrossel 16, die wie in Figur 5 dargestellt aussieht, verklebt wird. Die aktivierten Klebstoffschichten 23 trennen die nebeneinander in der Düsenfläche 12 mündenden Drosseldüsen genauso gas- bzw. luftdicht voneinander, wie es die Lötverbindungen 15 des vorhergehend beschriebenen Ausführungsbeispiels vermögen.10 shows that, as a result, the perforated plates 1, 2 are firmly bonded together and sealed by activated adhesive layers 23, which form the adhesive from the burst capsules 22, and the remaining, undisplaced capsules 24 by means of a gaseous (eg compressed air ) or liquid (eg, water) fluid 25 may be blown or purged from the plate assembly through the holes 5, 6. It is not shown in the drawing that the plate composite consisting of the inner perforated plates 1, 2 is bonded to the outer perforated plates 3, 4 (see also FIG. 3) by means of the capsules 20 for the finished air restrictor 16, which looks as shown in FIG. The activated adhesive layers 23 separate the throttle nozzles opening adjacent to one another in the nozzle surface 12 in the same gas-tight or airtight manner as the solder joints 15 of the previously described embodiment are capable of doing.

Figur 11 zeigt die im Zusammenhang mit Figur 1a bereits beschriebenen Lochplatten 1, 2 zusammen mit jeweils doppelseitig adhäsiven Klebefolien 26 als Ausgangsmaterialien für ein alternatives Klebeverfahren. Jede Klebefolie 26 hat eine 0,01 Millimeter bis 0,20 Millimeter betragende Folienstärke und eine mit der zweiten Lochplatte 2 im Wesentlichen kongruente Innen- und Außenkonturierung. Die Klebefolien 26 haben also ein mit den großen Löchern 6 der zweiten Lochplatte 2 im Wesentlichen kongruentes Lochmuster.FIG. 11 shows the perforated plates 1, 2 already described in connection with FIG. 1a together with respectively double-sided adhesive adhesive films 26 as starting materials for an alternative bonding process. Each adhesive film 26 has a film thickness of 0.01 to 0.20 millimeters and an inner and outer contour substantially congruent with the second orifice plate 2. The adhesive films 26 thus have a hole pattern that is essentially congruent with the large holes 6 of the second perforated plate 2.

Figur 12 zeigt, dass die Lochplatten 1, 2 und die Klebefolien 26 in der Positioniervorrichtung 10 zu einem Paket gestapelt werden, das gemäß Figur 13 durch die Kraft F zusammengedrückt wird, so dass das Paket nach seiner Entnahme aus der Positioniervorrichtung 10 durch die Klebefolien 26 gegebene, gas- bzw. luftdichte Verklebungen 27 aufweist, wie dies in Figur 14 dargestellt ist. Durch diese Verklebungen 27 sind die Lochplatten 1, 2 fest miteinander verbunden. Zeichnerisch nicht dargestellt ist, dass das aus den inneren Lochplatten 1, 2 und den dazwischen eingefügten Klebefolien 26 bestehende Paket mit den äußeren Lochplatten 3, 4 (vgl. Figur 3) mittels weiterer solcher doppelseitig wirksamen Klebefolien zur fertigen Luftdrossel, die wie in Figur 5 dargestellt aussieht, ebenso verklebt wird. Die weiteren Klebefolien haben jeweils ein mit den kleinen Löchern 5 der ersten Lochplatten 1 im Wesentlichen kongruentes Lochmuster. Die Verwendung sämtlicher Klebefolien zum Verkleben der Lochplatten 1 bis 4 ermöglicht deren Ausbildung nicht nur als Metallbleche, sondern auch aus einem nicht-metallischen Werkstoff, z. B. Kunststoff.FIG. 12 shows that the perforated plates 1, 2 and the adhesive films 26 in the positioning device 10 are stacked into a package which is compressed according to FIG. 13 by the force F, so that the package, after its removal from the positioning device 10, passes through the adhesive films 26 given, gas or airtight bonds 27, as shown in Figure 14. Through these bonds 27, the perforated plates 1, 2 are firmly connected. The drawing does not show that the package consisting of the inner perforated plates 1, 2 and the adhesive sheets 26 interposed therebetween, with the outer perforated plates 3, 4 (see FIG. 3) by means of further such double-sidedly effective adhesive foils for the finished air choke, as in FIG shown looks, is also glued. The further adhesive films each have a hole pattern that is essentially congruent with the small holes 5 of the first perforated plates 1. The Use of all adhesive films for bonding the perforated plates 1 to 4 allows their training not only as metal sheets, but also from a non-metallic material, eg. B. plastic.

Figur 15 zeigt einen Dichtmittelbehälter 28 mit einem Dichtmittelbad 29, das aus einer Flüssigkeit mit darin enthaltenen mikroskopisch-feinen, synthetischen Partikeln besteht, deren Aufgabe es ist, sich in Spalten festzusetzen und letztere dadurch dauerhaft zu verschließen. Eine derartige Dichtflüssigkeit wird z. B. von der Firma Adolf Würth GmbH, DE unter dem Handelsnamen "Kühlerdicht" zum Abdichten von Lecks in Automobil-Kühlern angeboten. Der aus den ersten Lochplatten 1 und der zweiten Lochplatte 2 und gegebenenfalls auch aus der dritten und vierten Lochplatte 3, 4 ( in Figur 15 zeichnerisch nicht dargestellt) bestehende Plattenstapel, dessen Lochplatten bereits mittels des Lötverfahrens (vgl. Figuren 1a bis 4) oder eines der Klebeverfahren (vgl. Figuren 6 bis 10 bzw. 11 bis 14) oder durch Verschraubungen fest miteinander verbunden worden sind, wird in das Dichtmittelbad 29 eine Zeit lang eingetaucht und gegebenenfalls dabei in letzterem zur besseren Verteilung der Partikel bewegt. Besagte Partikel setzen sich in den außerhalb der kleinen und großen Löcher 5, 6 liegenden Zwischenräumen zwischen den Lochplatten 1, 2 fest, z. B. an Orten, wo die Verklebung oder Verlötung unvollständig oder beschädigt ist oder, z. B. im Falle der Verschraubung, die Lochplatten nicht hinreichend dicht aneinander anliegen. Nach der Entnahme des Plattenstapels aus dem Dichtmittelbad 29 wird die Flüssigkeit aus dem Plattenstapel verdampft oder verdunstet.FIG. 15 shows a sealant container 28 with a sealant bath 29, which consists of a liquid with microscopically fine, synthetic particles contained in it, the object of which is to settle into gaps and thereby permanently close the latter. Such a sealing liquid is z. B. offered by the company Adolf Würth GmbH, DE under the trade name "radiator leak" for sealing leaks in automotive radiators. The plate stack consisting of the first perforated plates 1 and the second perforated plate 2 and optionally also of the third and fourth perforated plates 3, 4 (not shown in the drawing), the perforated plates of which are already by means of the soldering process (see FIGS The bonding method (see Figures 6 to 10 or 11 to 14) or by screwing firmly connected to each other is immersed in the sealant 29 for a time and possibly moved in the latter for better distribution of the particles. Said particles settle in the gaps outside the small and large holes 5, 6 between the perforated plates 1, 2 fixed, z. B. in places where the bonding or soldering is incomplete or damaged or, z. B. in the case of screwing, the perforated plates do not rest sufficiently close to each other. After removal of the plate stack from the sealant bath 29, the liquid is evaporated or evaporated from the plate stack.

Figur 16 zeigt, dass danach die nicht in den Spalten zwischen den Lochplatten 1, 2 der Luftdrossel 16 festgesetzten Restpartikel 30 mittels des bereits erwähnten Fluids 25 aus dem Plattenstapel herausgeblasen oder -gespült werden. Die in dem Plattenstapel verbleibenden und in dessen Spalten eingelagerten Partikel bilden im Wesentlichen gas- bzw. luftdichte Dichtmittelschichten 31.FIG. 16 shows that thereafter the residual particles 30 not fixed in the gaps between the perforated plates 1, 2 of the air throttle 16 are blown out of the plate stack or flushed out by means of the already mentioned fluid 25. The particles remaining in the plate stack and embedded in the gaps thereof essentially form gas-tight or airtight sealant layers 31.

Figur 17 zeigt eine Bogenbremse 32 zum Bremsen von Bogen 33 aus Bedruckstoff (vgl. Figur 18).17 shows a sheet brake 32 for braking sheets 33 of printing material (compare FIG. 18).

Die Bogenbremse 32 umfasst Bremseinheiten 34 und zwischen letzteren angeordnete Stützeinheiten 35. Die Bremseinheiten 34 weisen jeweils mindestens ein umlaufendes Bremselement 36 auf, welches eine Bremswalze oder -scheibe oder vorzugsweise ein Bremsband oder―riemen ist. Die Stützeinheiten 35 sind jeweils mit besagter Düsenfläche 12 zum per Luftpolster erfolgenden bzw. pneumatischen Abstützen der abzubremsenden Bogen 33 ausgestattet. In der Düsenfläche 12 münden die Luftauslässe 11 als sogenannte Drosseldüsen. In jede Stützeinheit 35 sind eine Vielzahl der nach einem der in den Figuren 1 bis 16 dargestellten Verfahren hergestellten Luftdrosseln 16 integriert.The sheet brake 32 comprises brake units 34 and support units 35 arranged between the latter. The brake units 34 each have at least one circulating brake element 36, which is a brake roller or disc or preferably a brake band or belt. The support units 35 are each equipped with said nozzle surface 12 for taking place by air cushion or pneumatic support the sheet 33 to be braked. In the nozzle surface 12, the air outlets 11 open as so-called throttle nozzles. In each support unit 35, a plurality of the air throttles 16 manufactured according to one of the methods shown in Figures 1 to 16 are integrated.

Figur 18 zeigt eine Maschine 37 zum Verarbeiten der Bogen 33. Die Maschine 37 ist eine Druckmaschine, vorzugsweise eine Perfektor-Druckmaschine zum beidseitigen Bedrucken der Bogen 33, und umfasst einen Bogenausleger 38, dessen Bestandteil die Bogenbremse 32 ist.FIG. 18 shows a machine 37 for processing the sheets 33. The machine 37 is a printing machine, preferably a perfector printing machine for double-sided printing of the sheets 33, and comprises a sheet delivery arm 38, the component of which is the sheet brake 32.
