Abstract

Die Erfindung betrifft eine Vorrichtung zum Aufbringen einer Flachenpressung unter Verwendung einer kontinuierlich arbeitenden Presse, gekennzeichnet durch Mehrlagenbänder, die auf Rollen mit vollnadelig angeordneten Lagernadeln von gleicher Länge wie die Länge der Rolle und diese abwälzend auf durchgehenden Wellen reihenweise versetzt oder auf geteilten, um wenig mehr als Rollendurchmesser gegeneinander reihenweise versetzt und gegen die Lagerbänder hinsichtlich der Wälzbewegungen aufnehmenden Laufflächen und Hohlräumen nach aussen dicht gehaltenen Wellen so gelagert sind, dass die beim Betrieb der Maschine, besonders in den Mehrlagenbändern auftretenden Biegespannungen und Hertz'schen Pressungen die für Dauerwechselfestigkeit der verwendeten Bandwerkstoffe erforderlichen Grenzwerte nicht überschreiten. Die Aussenfläche der Rollen, auf denen die Mehrlagenbänder laufen, besitzen eine ungefähr tonnenförmige Form, die dem Verlauf der Biegelinie des als Träger mit Flächenlast aufgefassten, von der Rolle mit ihrem grössten Durchmesser gestützen Mehrlagenbandes so angepasst ist, dass entlang der Berührungslinie zwischen Band und tonnenförmiger Rolle gleiche Hertz'sche Pressung herrscht. Die erfindungsgemässe Vorrichtung besitzt den grossen Vorteil, dass auf die Rückseite der Pressbander ein gleichmässiger Flachendruck ausgeubt werden kann, der eine einwandfreie kontinuierliche Herstellung von Schichtstoffen aller Art ermöglicht.The invention relates to a device for applying a flat pressure using a continuously operating press, characterized by multi-layer belts, which are arranged on rollers with full-needle bearing needles of the same length as the length of the roller, and these are shifted in rows on continuous shafts or on split, by little more staggered as a roll diameter against each other and against the bearing belts with respect to the rolling surfaces and cavities absorbing rolling movements to the outside, such that the bending stresses and Hertzian pressures that occur during operation of the machine, particularly in the multilayer belts, are necessary for the fatigue strength of the belt materials used Do not exceed limit values. The outer surface of the rolls on which the multilayer belts run have an approximately barrel-shaped shape, which is adapted to the course of the bending line of the multilayer belt, which is understood as a carrier with a surface load and is supported by the roll with its largest diameter, in such a way that along the line of contact between the belt and the barrel-shaped Role is the same Hertzian pressure. The device according to the invention has the great advantage that a uniform surface pressure can be exerted on the back of the press belt, which enables a perfect continuous production of all types of laminates.

Description

Die Erfindung betrifft eine Vorrichtung zum Aufbringen einer Flächenpressung auf endlose umlaufende Pressbänder, insbesondere an Doppelbandpressen.The invention relates to a device for applying surface pressure to endless rotating press belts, in particular to double belt presses.

Bei der Ausübung hoher Flächendrucke auf endlose um Trommeln umlaufende Pressbänder, insbesondere an Doppelbandpressen, besteht das Problem darin, auf die Rückseite der Pressbänder einen gleichmässigen Flächendruck auszuüben, um eine einwandfreie kontinuierliche Herstellung von Schichtstoffen oder Laminaten zu ermöglichen. Zur Lösung dieses Problems sind schon eine ganze Reihe von Vorschlägen gemacht worden, die jedoch teilweise aufwendig sind, erhebliche Nachteile aufweisen und nicht befriedigt haben.When exerting high surface pressures on endless press belts revolving around drums, in particular on double belt presses, the problem is to exert a uniform surface pressure on the back of the press belts in order to enable perfect continuous production of laminates or laminates. A whole series of proposals have already been made to solve this problem, but some of them are complex, have considerable disadvantages and have not been satisfied.

So beschreibt die DE-OS 20 37 442 eine mit endlosem Band und Gegenband arbeitende Presse zur kontinuierlichen Herstellung von geformten oder gepressten Werkstoffen, die dadurch gekennzeichnet ist, dass die Abstützung der Bänder durch eine Reihe von zusammenwirkenden Rollen erfolgt, die jeweils um eine zur Bewegungsrichtung der Bänder senkrecht stehende Achse drehbar sind und Mittel zum Einstellen des Spaltes zwischen den beiden Reihen von Rollen und/oder zum Einstellen einer Kraft, welche die beiden Reihen von Rollenelementen gegen eine sie auseinanderdrückende Bewegung vorspannt, so dass die beiden Reihen von Rollenelementen auf ein zwischen den endlosen Bändern liegendes Objekt eingestellt werden können.For example, DE-OS 20 37 442 describes a press working with an endless belt and counter-belt for the continuous production of shaped or pressed materials, which is characterized in that the belts are supported by a series of interacting rollers, each one about the direction of movement the belts are rotatable perpendicular axis and means for adjusting the gap between the two rows of rollers and / or for adjusting a force which biases the two rows of roller elements against a movement which pushes them apart, so that the two rows of roller elements on a between object lying on the endless bands can be set.

Aus der DE-AS 1 004 368 ist eine kontinuierlich arbeitende Bandpresse bekannt mit mindestens einem zur Druckübertragung auf das Preßgut dienenden flexiblen, endlosen, vorzugsweise aus Stahl bestehenden Band und mit zur Druckübertragung auf das Band dienenden eng aneinandergereihten losen Wälzkörpern, die dadurch gekennzeichnet ist, daß die Wälzkörper mit bundartigen, zylindrischen Erweiterungen versehen und in ihrer Längsrichtung jeweils um eine Bundteilung zueinander versetzt und derart kammartig ineinandergreifend angeordnet sind, daß sie zum mindesten mit den Stirnseiten der Erweiterungen eng aneinanderliegen.DE-AS 1 004 368 discloses a continuously operating belt press with at least one flexible, endless belt, preferably made of steel, which is used to transmit pressure to the material to be pressed, and with to transmit pressure the band serving closely lined loose rolling elements, which is characterized in that the rolling elements are provided with collar-like, cylindrical extensions and in the longitudinal direction offset from one another by a collar division and arranged in such a comb-like manner that they lie closely together, at least with the end faces of the extensions .

Die DE-PS 2 157 746 beschreibt eine Presse zur Ausübung einer Flächenpressung auf einen Längenabschnitt einer vorlaufenden Bahn, insbesondere eine Presse zur kontinuierlichen Herstellung von Holzspanplatten und ähnlichen Werkstoffen, bei der die Bahn zwischen endlosen, der Vorlaufrichtung der Bahn entsprechend mitumlaufenden, über die Breite der Bahn sich erstreckenden Formbändern geführt ist und bei der zwischen den Formbändern und einer oberhalb und einer unterhalb der Bahn vorgesehenen Stützkonstruktion abrollende, in endloser Folge in der zur Bahn senkrechten Längsebene umlaufende Rollen vorgesehen sind, die den Arbeitsdruck von der Stützkonstruktion auf die Formbänder übertragen, wobei die Rollen in eine Mehrzahl im Verhältnis zur Bahnbreite kurzer Rollen unterteilt sind und, mit einem eigenen Führungsmittel versehen, kettenartig miteinander verbunden sind. Diese Presse ist dadurch gekennzeichnet, dass die Rollenkettenanordnung aus vielen quer zur Bahn dicht benachbarten, in Vorlaufrichtung konstante Breite aufweisenden, voneinander unabhängige Einzelstränge bildenden Rollenketten aufgebaut ist, jede Rollenkette mehrere nebeneinanderliegende Rollen enthält und die Laschen ausschliesslich dazwischen angeordnet sind und die die Laschen enthaltenden Stossstellen zweier nebeneinanderliegender Rollen innerhalb jeder Rollenkette in Vorlaufrichtung seitlich gegeneinander versetzt sind.DE-PS 2 157 746 describes a press for exerting a surface pressure on a longitudinal section of a leading web, in particular a press for the continuous production of chipboard and similar materials, in which the web runs along the width between endless, corresponding to the leading direction of the web the web of extending forming belts is guided and in which rollers rolling between the forming belts and a support structure provided above and below the web are provided in an endless sequence in the longitudinal plane perpendicular to the web, which transfer the working pressure from the supporting structure to the forming belts, the rollers being divided into a plurality of rollers which are short in relation to the web width and, provided with their own guide means, are connected to one another like a chain. This press is characterized in that the roller chain arrangement is made up of many roller chains that are closely adjacent to the web and have independent widths that are independent of one another and have a constant width in the forward direction, each roller chain contains several rollers lying side by side, and the plates are arranged exclusively between them, and the joints containing the plates two adjacent rollers within each roller chain are laterally offset from each other in the forward direction.

Gegenstand der CH-PS 327 433 ist eine Einrichtung zum kontinuierlich fortschreitenden Pressen eines plattenförmigen Gutes mit zwei als Preßflächen und gleichzeitig als Förderbänder wirksamen, flexiblen endlosen Bändern. Der Druck auf die Rückseite der Bänder wird durch in beweglichen Ketten angeordnete Wälzkörper aus Rundstäben übertragen, wobei die Wälzkörper in bezug auf die Breite der Pressbänder verkürzt und gegeneinander versetzt angeordnet sind.The subject of CH-PS 327 433 is a device for the continuously progressive pressing of a plate-shaped material with two flexible endless belts that act as pressing surfaces and at the same time as conveyor belts. The pressure on the back of the belts is transmitted by rolling bodies made of round bars arranged in movable chains, the rolling bodies being shortened with respect to the width of the pressing belts and being offset with respect to one another.

Schliesslich betrifft die DE-OS 28 53 285 eine Vorrichtung zum Aufbringen einer Flächenpressung auf fortschreitende Werkstücke mit mindestens einem umlaufenden Pressband, welches von mehreren gleichartigen, mit parallelen Achsen in einer Reihe angeordneten Rollen an das Werkstück anpressbar ist, wobei die Rollen ortsfest gelagert und an ihren von dem zugehörigen Pressband abgewandten Seiten an als Widerlager ausgebildeten Wälzkörpern abgestützt sind, die dadurch gekennzeichnet ist, dass jeweils zwei nebeneinanderliegende Rollen einem oder mehreren auf einer gemeinsamen Achse angeordneten Wälzkörpern zugeordnet sind.Finally, DE-OS 28 53 285 relates to a device for applying surface pressure to progressive workpieces with at least one rotating press belt which can be pressed against the workpiece by several similar rollers arranged in a row with parallel axes, the rollers being mounted in a stationary manner and on their sides facing away from the associated press belt are supported on rolling bodies designed as abutments, which is characterized in that two adjacent rollers are assigned to one or more rolling bodies arranged on a common axis.

Einen etwas anderen Lösungsweg zur Erreichung einer gleichmäßigen Druckverteilung beschreibt die DE-PS 27 35 142. Dort wurde versucht, dieses Problem durch Anwendung eines mehrschichtigen Preßbandes zu lösen, das durch Wälzkörper gestützt wird, die an Druckplatten angeordnet sind.DE-PS 27 35 142 describes a somewhat different approach to achieving a uniform pressure distribution. There, attempts were made to solve this problem by using a multi-layer press belt which is supported by rolling elements which are arranged on pressure plates.

Zu den eingangs genannten Nachteilen der bekannten Vorrichtungen kommt noch hinzu, daß es mit den so ausgestatteten Doppelbandpressen nicht möglich ist, geformte oder gepreßte Werkstücke oder Schichtstoffe herzustellen, die eine geringere Breite als die Preßbänder selbst aufweisen.In addition to the disadvantages of the known devices mentioned at the outset, the fact that the double belt presses equipped in this way is not possible to produce shaped or pressed workpieces or laminates which have a smaller width than the press belts themselves.

Die Aufgabe der Erfindung ist nun darin zu sehen, eine Vorrichtung zum Aufbringen einer Flächenpressung auf endlose umlaufende Pressbänder, insbesondere an Doppelbandpressen, zu schaffen, mit der es gleichzeitig möglich ist, Schichtstoff- oder Laminaterzeugnisse herzustellen, die jede beliebige Breite innerhalb der Breite des Pressbandes aufweisen können, ohne dass dazu besonders zusätzliche Einrichtungen erforderlich sind.The object of the invention is to be seen in a device for applying a surface pressure to end to create loosely rotating press belts, in particular on double belt presses, with which it is possible at the same time to produce laminate or laminate products which can have any width within the width of the press belt, without the need for additional devices.
