Description

Die Erfindung betrifft eine Doppelbandpresse gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a double belt press according to the preamble of claim 1.

Bei Doppelbandpressen ist es von entscheidender Bedeutung, die Abmessungen der Maschine ohne völlige Neukonstruktion der jeweiligen Bearbeitungsaufgabe oder den Prozessbedingungen anpassen zu können. Je nachdem sind dazu isobar oder isochor wirkende Maschinen erforderlich, deren Realisierung unterschiedliche konstruktive Lösungen verlangt.With double belt presses, it is vitally important to be able to adjust the dimensions of the machine without having to completely redesign the machining task or process conditions. Depending on this, isobaric or isochoric machines are required, the implementation of which requires different constructive solutions.

Stand der Technik sind Maschinen, die derzeit gebaut werden nach Prospekten der Firmen Hymmen GmbH & Co. KG, Kurt Held GmbH (der Firma des Anmelders) und Contipress GmbH & Co. KG, die beigefügt sind. Ferner sind DE-PS 27 37 629, DE-PS 936 718, DE-PS 20 61 195, DE-OS 23 13 902, AT-PS 176349, US-PS 3 521 552, DE-OS 2 140 105, DE-PS 22 65 401 u.a. als Beispiel dafür zu nennen, dass sich der Stand der Technik nicht damit beschäftigt hat, die Hauptbauelemente einer Doppelbandpresse so auszubilden und in der Maschine anzuordnen, dass zur Anpassung der Maschine an die Bearbeitungsaufgabe nur die- jenigen Elemente angepasst werden, die dieser Anpassung bedürfen, alle anderen jedoch unverändert Verwendung finden können.The state of the art are machines that are currently being built according to brochures from Hymmen GmbH & Co. KG, Kurt Held GmbH (the company of the applicant) and Contipress GmbH & Co. KG, which are included. Furthermore, DE-PS 27 37 629, DE-PS 936 718, DE-PS 20 61 195, DE-OS 23 13 902, AT-PS 176349, US-PS 3 521 552, DE-OS 2 140 105, DE- PS 22 65 401 and others As an example of the fact that the state of the art has not dealt with designing the main components of a double belt press and arranging them in the machine in such a way that only those elements that need this adjustment are adapted to adapt the machine to the machining task, all others can still be used unchanged.

Die gemäss dem Prospekt der Kurt Held GmbH mit der Bezeichnung "Kontinuierliche Laminiermaschine E 178" bekannte Doppelbandpresse besitzt zwei übereinanderliegende Bandeinheiten, die in einem aus Trägerrahmen bestehenden Pressengestell gelagert sind. Jede Bandeinheit besitzt eine Heiz- und Umlenktrommel, um die ein Pressband geschlungen ist. Die Trommeln sind im Pressengestell gelagert, wobei ein Lager als Spannlager zur Regulierung der Spannung des Pressbandes ausgebildet ist.The double belt press known according to the brochure of Kurt Held GmbH with the designation "Continuous Laminating Machine E 178" has two stacked belt units which are mounted in a press frame consisting of a carrier frame. Each belt unit has a heating and deflection drum around which a press belt is wrapped. The drums are mounted in the press frame, a bearing being designed as a tension bearing for regulating the tension of the press belt.

Das zu laminierende Gut wird zwischen den Bändern geführt, wobei der Druck auf die Bandrückseiten mittels Heizplatten, die mit einer Einrichtung zur Stützung der Pressbänder versehen sind, aufgebracht wird. Diese Heizplatten sind im Pressengestell befestigt. Die von dem Pressgut ausgehenden Reaktionskräfte werden von seitlich an der Doppelbandpresse angebrachten Spannplatten, die die obere und untere Bandeinheit miteinander verklammern, aufgenommen.The material to be laminated is guided between the belts, the pressure being applied to the rear of the belts by means of heating plates which are provided with a device for supporting the press belts. These heating plates are attached to the press frame. The reaction forces emanating from the material to be pressed are absorbed by clamping plates attached to the side of the double belt press, which clamp the upper and lower belt units together.

Aufgrund der Patentschrift DE-PS 22 65 401 und der Auslegeschrift DE-AS 28 19 943 sind Doppelbandpressen bekannt geworden, deren Pressengestell aus einzelnen Trägern besteht. Diese Träger sind seitlich mit Gewindespindeln miteinander verklammert.Due to the patent specification DE-PS 22 65 401 and the design specification DE-AS 28 19 943 double belt presses have become known, the press frame of which consists of individual supports. These brackets are laterally clamped together with threaded spindles.

Nachteilig bei diesen Doppelbandpressen ist, dass keine Möglichkeit besteht, die Höhe des Pressenspaltes zu verändern, um so die Doppelbandpresse den Erfordernissen unterschiedlichen Pressgutes anzupassen. Ebenfalls ist es nicht möglich, die Pressbänder einfach und schnell auszutauschen. Weiterhin zwingt dieser Stand der Technik den Maschinenbauer bisher, die statische Auslegung der tragenden Pressenteile, z. B. für jede Maschinenbreite neu zu bestimmen und dementsprechend diese Teile neu zu dimensionieren und zu fertigen. Da sich z. B. mit der Maschinenlänge die Aufbiegung der Druckplatten in Längsrichtung erhöht, sieht DE-PS 24 51 894 vor, jedes Pressenjoch mit eigener Spaltverstellung über Gewindespindeln auszustatten, was zu einer teueren Überdimensionierung führen würde, wenn die Maschine nur für niedrige spezifische Flächendrücke vorzusehen ist.A disadvantage of these double belt presses is that there is no possibility of changing the height of the press nip in order to adapt the double belt press to the requirements of different pressing goods. It is also not possible to replace the press belts quickly and easily. Furthermore, this state of the art has so far forced the machine builder to design the structural parts of the press, e.g. B. redetermine for each machine width and accordingly re-dimension and manufacture these parts. Since z. B. with the machine length increases the bending of the pressure plates in the longitudinal direction, DE-PS 24 51 894 provides to equip each press yoke with its own gap adjustment via threaded spindles, which would lead to an expensive oversizing if the machine is only to be provided for low specific surface pressures.

Ähnliches gilt für die Ausbildung der Druckplatten, die für isochore Doppelbandpressen wesentlich anders konstruiert werden müssen als für isobare Maschinen, obwohl alle übrigen Hauptelemente bei sonst gleichen Anforderungen durch den Prozess unverändert bleiben könnten. An einen schnellen Wechsel von Druckplatten jeweils für isobaren oder isochoren Betrieb inderselben Maschine zur Erweiterung ihrer Anwendung und damit zur Erhöhung ihrer Wirtschaftlichkeit ist bei den bekannten Doppelbandpressen nirgendwo gedacht.The same applies to the design of the printing plates, which have to be constructed significantly differently for isochore double belt presses than for isobaric machines, although all other main elements could remain unchanged by the process with otherwise identical requirements. Nowhere is known in the known double belt presses to quickly change printing plates for isobaric or isochoric operation in the same machine in order to expand their application and thus to increase their economy.

Der Erfinder hat sich, ausgehend von diesem Stand der Technik, die Aufgabe gestellt, die Hauptelemente einer Doppelbandpresse so auszugestalten und einander zuzuordnen, dass sie durch Variation der Anzahl weniger standardisierter Teile und einfachem Austausch weniger Komponenten bzw. Hinzufügen weniger weiterer Teile der jeweiligen Bearbeitungsaufgabe leicht anpassbar ist, ohne dass eine komplette Neukonstruktion mit entsprechender neuer Dimensionierung des gesamten Pressengestells notwendig ist. Dabei soll sowohl eine einfache und schnelle Verstellung des Preßspaltes als auch ein einfacher Austausch der Heizplatten oder Pressbänder gewährleistet sein.Based on this prior art, the inventor has set himself the task of designing the main elements of a double belt press and assigning them to one another in such a way that they can be easily varied by varying the number of fewer standardized parts and simply replacing fewer components or adding fewer additional parts to the respective machining task is adaptable without the need for a completely new construction with corresponding new dimensioning of the entire press frame. Both simple and quick adjustment of the press nip and simple replacement of the heating plates or press belts should be ensured.

Die Lösung dieser Aufgabe wird durch die im Patentanspruch 1 beschriebene technische Lehre vermittelt.The solution to this problem is conveyed by the technical teaching described in claim 1.

In der Zeichnung ist eine Ausführungsform der Erfindung dargestellt. Dabei zeigen Fig. 1 eine Presse in perspektivischer Sicht und Fig. 2 eine Presse im Schnitt.In the drawing, an embodiment of the invention is shown. 1 shows a press in perspective and FIG. 2 shows a press in section.

Wie anhand der Fig. 2 ersichtlich, besteht das Pressengestell aus einem L-Gestell 16, das an der Rückseite der Doppelbandpresse vertikal stehende Schenkel 15 besitzt. Diese Schenkel 15 nehmen die untere rückseitige Lagerbrücke 2 auf. Die Stützträger 1 der Doppelbandpresse sind an ihren beiden Enden mit angeschweissten Kopfplatten I'versehen, in denen sich Sägezahnprofile befinden, z.B. nach DE-PS 27 37 629, Seite 10, Einzelheit X, die wiederum eine hoch belastbare Verbindung zu den Lagerbrücken 2 herstellen. Diese Stützträger 1 sind nebeneinanderliegend quer zur Vorlaufrichtung der Pressbänder in dem Raum zwischen den Heiztrommeln 19 und den Umlenktrommeln 20 eingebaut, wie insbesondere der Fig. 1 entnommen werden kann.As can be seen from FIG. 2, the press frame consists of an L-frame 16 which has legs 15 standing vertically on the back of the double belt press. These legs 15 accommodate the lower rear bearing bracket 2. The support beams 1 of the double belt press are provided at both ends with welded head plates I'in which there are sawtooth profiles, for example according to DE-PS 27 37 629, page 10, detail X, which in turn produce a highly resilient connection to the bearing bridges 2. These support beams 1 are installed adjacent to one another transversely to the direction of advance of the press belts in the space between the heating drums 19 and the deflection drums 20, in particular 1 can be seen.

Die Verbindung zwischen der oberen Doppelbandeinheit 3 und der unteren Doppelbandeinheit 4 wird unter Verwendung der Spannbrücke 2 als gemeinsamer Träger aller notwendigen Muttergewinde bei 6, 6', 6", 6"', sinngemäss an beiden Längsseiten der Maschine durch Verstellgewindespindeln 7 hergestellt.The connection between the upper double belt unit 3 and the lower double belt unit 4 is established using the tension bridge 2 as a common carrier of all necessary nut threads at 6, 6 ', 6 ", 6"', analogously on both longitudinal sides of the machine by means of adjusting screw spindles 7.

Die Heizplatten 8 und 9 sind an den Stützträgern 1 mit Hilfe von Führungsschienen 10 so befestigt, dass sie, nach Entfernen der Schalenkupplungen 11 auf nicht dargestellten Führungsrollen bewegt, aus der oberen bzw. unteren Doppelbandeinheit herausgezogen und gegebenenfalls durch solche, z. B. eines anderen Wirkprinzips, ersetzt werden können.The heating plates 8 and 9 are attached to the support beams 1 with the aid of guide rails 10 so that, after removal of the shell couplings 11, they move on guide rollers (not shown), are pulled out of the upper or lower double belt unit and, if necessary, by such, e.g. B. another principle of action, can be replaced.

Die planparallele Preßspaltverstellung wird erfindungsgemäss dadurch gelöst, dass die Verstellgewindespindeln 7 aus zwei Teilen mit gegensinnigem Gewinde dargestellt werden, die über demontierbare Schalenkupplungen 11 verdrehsicher miteinander verbunden und von einer Rollenkette 12 angetrieben werden, die von einem Stellantrieb 13 gezogen wird.The plane-parallel adjustment of the press nip is achieved according to the invention in that the adjusting threaded spindles 7 are made up of two parts with opposite threads, which are connected to one another in a rotationally secure manner via removable shell couplings 11 and are driven by a roller chain 12 which is pulled by an actuator 13.

Der Pressbandwechsel wird einerseits gelöst durch die schnell demontierbaren Schalenkupplungen 11, andererseits dadurch, dass die obere Doppelbandeinheit 3 gegen Anschläge 14 an den Schenkeln 15 des L-Gestells 16 und eines auskragenden Ansatzes an der hinteren oberen Lagerbrücke (2') gefahren wird, wo sich das Gewicht dieser Doppelbandeinheit 3 über die Verstellgewindespindeln 7 in der anliegenden Spannbrücke 2' und durch eine Spange im Schenkel 15 abstützt, sobald die Schalenkupplungen 11 zum Pressbandwechsel oder zum Ausziehen der Heizplatten 8 oder 9 entfernt werden. Diese Anordnung ermöglicht, wie vorerwähnt, auch den Austausch der Heizplatten 8 und 9.The press belt change is solved on the one hand by the quickly removable shell couplings 11, and on the other hand that the upper double belt unit 3 is moved against stops 14 on the legs 15 of the L-frame 16 and a cantilevered shoulder on the rear upper bearing bracket (2 '), where the weight of this double belt unit 3 is supported via the adjusting screws 7 in the adjacent clamping bridge 2 'and by a clip in the leg 15 as soon as the shell couplings 11 are removed for changing the press belt or for pulling out the heating plates 8 or 9. As mentioned above, this arrangement also makes it possible to replace the heating plates 8 and 9.

Die Festlager 17 und die Spannlager 18 sind auf die Stirnseite der Lagerbrücken 2 und 2' aufgeschraubt, ihre Dimensionen können bei Bemessung der einzubauenden Wälzlager für die grössten vorkommenden Maschinen und bei Verwendung von Pressbandpaketsätzen nach DE-PS 27 35 142 für alle darzustellenden Maschinengrössen gleich sein. Das gleiche gilt, von der Länge abgesehen, für die Heiztrommel 19 und die Umlenktrommel 20.The fixed bearings 17 and the tensioning bearings 18 are screwed onto the end face of the bearing bridges 2 and 2 ', their dimensions can be the same for all the machine sizes to be represented when dimensioning the rolling bearings to be installed for the largest machines that occur and when using press belt package sets according to DE-PS 27 35 142 . The same applies, apart from the length, for the heating drum 19 and the deflection drum 20.

Die Stützträger haben eine Grundgestalt, die durch zusätzlichen Einbau von Stegen 5', 5", 5"' für einen weiten Bereich von Widerstandsmomenten dargestellt werden kann, ohne dass sich ihre übrige Gestalt unter zwingenden Kostenüberlegungen ändern muss, was insbesondere auch für die Kopfplatten 1' gilt.The support beams have a basic shape, which can be represented by additional installation of webs 5 ', 5 ", 5"' for a wide range of moments of resistance, without their remaining shape having to change under imperative cost considerations, especially for the head plates 1 'applies.

Wird höherer spezifischer Druck oder grössere Maschinenbreite verlangt, so werden neben höheren Widerstandsmomenten höhere Verstellgewindespindelquerschnitte aufgrund. der erhöhten Presskraft notwendig. Die einfache Lösung, die Verstellgewindespindeln 7 masslich unverändert in entsprechend grösserer Anzahl und mit kleinerem Abstand in den Lagerbrücken anzuordnen, ändert an den übrigen Teilen der Maschine nichts.If a higher specific pressure or a larger machine width is required, higher adjusting torque spindle cross-sections are required in addition to higher resistance moments. the increased pressing force necessary. The simple solution of arranging the adjusting screw spindles 7 unchanged in a correspondingly greater number and with a smaller distance in the bearing bridges does not change anything in the other parts of the machine.

Bei längeren Druckzonen ändert sich die Lagerbrücken-, die Heizplatten- und die Bandpaketlänge, während die übrigen Teile gleich bleiben, gegebenenfalls in anderer Anzahl eingehen. Der Stellantrieb 13 und die Untersetzungsgetriebe 13', ohne nennenswerten Aufwand von vornherein überdimensioniert, wirken auf alle erforderlichen Verstellgewindespindeln 7 über eine entsprechend längere Rollenkette 12, gegebenenfalls grösseren Querschnitts.In the case of longer pressure zones, the length of the bearing bridge, the heating plate and the belt package change, while the other parts remain the same, possibly in a different number. The actuator 13 and the reduction gear 13 ', oversized from the outset without any appreciable outlay, act on all the necessary adjusting threaded spindles 7 via a correspondingly longer roller chain 12, possibly with a larger cross section.

Soll eine Maschine für isochoren Betrieb nach DE-PS 27 35 142 oder für kombiniert isochorisobaren Betrieb nach der Offenlegungsschrift DE-At 31 35 031 (veröffentlicht am 24.3.1983) ausgerüstet werden, so kann man der Auswirkung unterschiedlicher geforderter Drücke auf das notwendige Widerstandsmoment des Pressbandes und den aus höherem Druck resultierenden höheren Bandzugkräften durch eine entsprechende Anzahl von Pressbandlagen in den Bandpaketen, mit denen die Maschine bestückt wird, Rechnung tragen. Mit dieser Massnahme ist es möglich, den Durchmesser der Heiztrommel 19 und der Umlenktrommel 20 sowie alle davon abhängigen Abmessungen der übrigen Grundelemente der Maschine unverändert beizubehalten.If a machine is to be equipped for isochoric operation according to DE-PS 27 35 142 or for combined isochorisobar operation according to the published patent application DE-At 31 35 031 (published on March 24, 1983), the effect of different required pressures on the necessary moment of resistance of the Press belt and the higher belt tensile forces resulting from higher pressure by a corresponding number of press belt layers in the belt packages with which the machine is equipped. With this measure, it is possible to keep the diameter of the heating drum 19 and the deflection drum 20 as well as all the dimensions of the other basic elements of the machine which are dependent thereon unchanged.

Eine erfindungsgemäss ausgestaltete Maschine erlaubt dem Maschinenbauer nicht nur den Bau gewisser Grundelemente in grösseren Serien ohne fixierten Auftrag und die Lieferung innerhalb kürzerer Lieferfristen. Sein Kunde kann jederzeit während der üblichen Nutzungsdauer seiner Doppelbandpresse auf eine andere Einsatzart oder Bearbeitungsaufgabe übergehen, die Kapazität erweitern u. ä., lediglich durch Austausch der betroffenen, von seinem Lieferanten bei Auftreten des geänderten Bedarfs angefertigten Hauptelemente.A machine designed according to the invention not only allows the machine builder to build certain basic elements in larger series without a fixed order and to deliver within shorter delivery times. His customer can switch to another type of application or processing task at any time during the normal service life of his double belt press, expand the capacity and. Ä., only by exchanging the main elements affected by his supplier when the changed need arises.
