Further, the membrane press on a means for applying the limited by the membrane and the pressure chamber with the press closed working space with pressurized fluid.
- the outside of the pressure chamber carries a membrane tensioning device acting on the membrane.
- the DE 38 27 497 A1 relates to a device for coating three-dimensional bodies with a film, with a table for the exclusion of a body to be coated, a body-lowerable pressure pad with a membrane, which is held in a box-shaped, bottom open carrier, and a disposed below the membrane, The outline of the body by far the following clamping frame for clamping the film.
- the box-shaped support consists of a heatable base plates and a vertically movable with respect to this, holding the membrane support frame.
- the DE 103 23 772 B3 discloses a method and an apparatus for three-dimensional film coating of flat workpieces with residual films.
- the device consists of a press with an upper and a lower press table and a divided by an inserted divider bar in working frame and rest frame lower frame and a top frame, which is located above the remaining film on the working frame.
- a cover membrane overlying the residual frame on each of its edges and the lower frame.
- the upper frame holds the remaining film and the cover membrane clamped.

- a displaceable strip is arranged which divides the upper frame and which covers, holds and seals the overlap.
- membrane holders are known in which the membrane is clamped at its peripheral edge continuously behind terminal strips, which are fixed for example with screws.
- membrane presses or laminators relatively frequently due change of the membrane are disadvantageously extensive installation work with a relatively large amount of time required because a corresponding number of screw connections must be solved and screwed after removing the old membrane and inserting the new membrane again. Such a change is necessary in practice about every two weeks.
- membrane presses which have heating plates on which components to be laminated, for example furniture parts, rest.
- a membrane is arranged, which is held at its edges via terminal strips by means of screw terminals.
- the terminal strips have on their back to the rear and bottom running bends, with which they are hung on the support frame.
- the support frame is vertically movable to clamp the membrane for the operation of the membrane press and to relax for a change of the membrane.
- the membrane must be prefabricated outside the membrane press by the terminal strips are attached in advance to the membrane. Thereafter, the membrane including the attached on the four sides of the membrane terminal strips must be stirred into the membrane press. This is relatively difficult because of the large areas and relatively high weight of the diaphragm and terminal strips.
- a disadvantage of the known prior art is further that the membrane has perforations at its edge to pass, for example, the screws through these perforations.
- these perforations weaken the membrane at its edge, so that the perforations are often the starting point of cracks, which can destroy the membrane completely.
- the US-A-6 120 238 describes a drawing bar in which an edge of a flexible web is clamped by means of a pinch roller lying in the drawing bar, and then by means of the draw bar to pull the web with a load on the ground. It is therefore about the transport of a load.

- the membrane can initially be inserted into the membrane press to set it free of the holding elements according to the invention. Thereafter, then a single operator around little by little, the holding elements with the membrane edge without tools use very quickly engage.
- the membrane change with the holding elements according to the invention takes only about a quarter of the time as in a conventional holder with a variety of screws using an additional tool, such as a wrench , must be solved or tightened.
- a first development of the membrane press according to claim 1 provides that the holding elements a cross bar have, on both sides of each a clamping web is arranged, wherein viewed in cross section, the clamping webs are oriented with their free end away from the crosspiece obliquely oriented towards each other, so that an opposite crosspiece to the opening is formed, which is tapered in the direction of the crosspiece extended, wherein the clamping bolt is disposed in a clamping position in the vicinity of the free ends between the membrane and a contact surface opposite the clamping surface, so that the membrane is fixed non-positively, and wherein the clamping bolt from the clamping position in the direction of the crosspiece can be raised, so that the membrane is dissolved.
- the holding elements have a transverse web which is rigidly connected at its one side directly to the support frame and at the other side a clamping web is arranged, seen in cross-section of the clamping web with its free end in the direction of the Quersteg away obliquely oriented to a clamping web facing the clamping surface of the support frame to extend, so that a transverse web to the opposite opening is formed, which widens conically in the direction of the crosspiece, wherein the clamping bolt in a clamping position in the vicinity of the free end between the membrane and a bearing surface lying opposite the clamping surface is arranged, so that as a diaphragm is fixed non-positively, and wherein the clamping bolt from the clamping position in the direction of the crosspiece can be raised, so that the membrane is released.
- the membrane can be easily inserted with its edge through the opening in the holding element according to the invention, wherein the clamping bolt manually by an operator or solely by the insertion of the membrane edge is raised. If the membrane is inserted with its edge sufficiently far into the retaining element, the operator can release the clamping bolt, so that it comes to rest between the membrane and the contact surface on one of the clamping webs. As a result, the membrane is fixed non-positively on the clamping surface of the clamping bar opposite thereto by a self-clamping effect of the clamping bolt.
- the operator can circumferentially connect the holding elements, which are selectively applied in a preferred embodiment, as far as the holding elements are distributed over the circumference of the membrane at intervals, with the membrane edge. If the support frame is moved along a tensioning direction, the clamping bolt moves further in the direction of the opening, so that the diaphragm is held in a force-fitting manner sufficiently firmly by the retaining element, the self-clamping effect of the clamping bolt being reinforced.
- the support frame is moved opposite, so that relaxes the membrane. Thereafter, the operator can now just around the respective clamping bolt simply lift out of the clamping position in the direction of the crosspiece, so that the membrane is easily and without the use of an additional tool from each support member is releasable. It may happen that the clamping bolt in the relaxed position of the membrane is fixed so that it must be solved for example by means of a light impact; However, this does not change the fact that a considerable saving of time is achieved when the membrane has to be replaced, since the application of a light impact is not as time-consuming as, for example, a rotating loosening of screws.
- the membrane edge is serrated or serrated, wherein the individual teeth or prongs are adapted to the buckle-like retaining element.
- the operator must simply insert the edge of the membrane or its teeth or prongs in the buckle or the buckle-like element, with a non-positive connection can be achieved.
- the retaining elements according to the invention can be dispensed with a perforation of the membrane at its edge, so that a destruction of the membrane, which can be caused for example by outgoing from the holes cracks, is avoided.
- the holding elements engage distributed over the circumference of the edge region on the membrane, and form a holding element row.
- the support frame can be designed circumferentially continuous or divided into sections.
- the holding elements are flexible at least for connecting the membrane to the holding elements
- the holding elements are associated with suspension elements, which are arranged between the holding elements and the support frame. This is advantageously achieved that the holding elements are not rigidly connected to the support frame in the relaxed position of the membrane, but are three-dimensionally movable, so that an even easier connection or introduction of the membrane results in the holding elements according to the invention.
- the holding elements may be associated with spring elements which are arranged between the holding element and the support frame.
- spring elements are beispiel.al coil springs.
- the support frame is associated with at least one adjusting means with which the support frame along the clamping direction is adjustable.

Demnach sind Membranhalterungen bekannt, bei denen die Membran an ihrem umlaufenden Rand durchgehend hinter Klemmleisten eingeklemmt ist, die beispielsweise mit Schrauben festgelegt sind. Bei einem im Betrieb von Membranpressen oder Laminatoren relativ häufig fälligen Wechsel der Membran sind hierbei nachteiligerweise umfangreiche Montagearbeiten mit relativ großem Zeitaufwand nötig, weil entsprechend viele Schraubverbindungen gelöst und nach dem Herausnehmen der alten Membran und dem Einsetzen der neuen Membran wieder festgeschraubt werden müssen. Ein solcher Wechsel ist in der Praxis ca. alle zwei Wochen notwendig.Accordingly, membrane holders are known in which the membrane is clamped at its peripheral edge continuously behind terminal strips, which are fixed for example with screws. In the operation of membrane presses or laminators relatively frequently due change of the membrane are disadvantageously extensive installation work with a relatively large amount of time required because a corresponding number of screw connections must be solved and screwed after removing the old membrane and inserting the new membrane again.

Nachteiligerweise muß die Membran allerdings außerhalb der Membranpresse vorkonfektioniert werden, indem die Klemmleisten vorab an der Membran angebracht werden. Danach muß die Membran einschließlich der an den vier Seiten der Membran angebrachten Klemmleisten in die Membranpresse eingerührt werden. Dies ist wegen der großen Flächen und wegen des relativ hohen Gewichts der Membran und der Klemmleisten relativ schwierig.But membrane presses are also known which have heating plates on which components to be laminated, for example furniture parts, rest. Above this, a membrane is arranged, which is held at its edges via terminal strips by means of screw terminals. The terminal strips have on their back to the rear and bottom running bends, with which they are hung on the support frame. The support frame is vertically movable to clamp the membrane for the operation of the membrane press and to relax for a change of the membrane. Disadvantageously, however, the membrane must be prefabricated outside the membrane press by the terminal strips are attached in advance to the membrane. Thereafter, the membrane including the attached on the four sides of the membrane terminal strips must be stirred into the membrane press. This is relatively difficult because of the large areas and relatively high weight of the diaphragm and terminal strips.
Nachteilig bei dem bekannten Stand der Technik ist weiterhin, daß die Membran an ihrem Rand Lochungen aufweist, um beispielsweise die Schrauben durch diese Lochungen hindurchzuführen. Diese Lochungen schwächen die Membran jedoch an ihrem Rand, so daß die Lochungen häufig Ausgangspunkt von Rissen sind, welche die Membran vollständig zerstören können.A disadvantage of the known prior art is further that the membrane has perforations at its edge to pass, for example, the screws through these perforations. However, these perforations weaken the membrane at its edge, so that the perforations are often the starting point of cracks, which can destroy the membrane completely.

Der Erfindung liegt die Aufgabe zugrunde, eine Membranpresse der eingangs genannten Art dahingehend zu verbessern, daß eine hohe Lebensdauer der Membran erzielt wird und daß ein Membranwechsel derart einfach durchführbar ist, daß eine erhebliche Zeiteinsparung erzielt wird.The invention has for its object to improve a membrane press of the type mentioned in that a high life of the membrane is achieved and that a membrane change is so easy to carry out that a considerable time savings.
Erfindungsgemäß wird die Aufgabe durch eine Membranpresse mit den Merkmalen des Anspruchs 1 gelöst. Die Aufgabe wird erfindungsgemäß auch durch eine Membranpresse mit den Merkmalen des Anspruchs 4 gelöst.According to the invention the object is achieved by a membrane press having the features of
Durch die erfindungsgemäße Ausgestaltung der Halteelemente wird vorteilhaft erreicht, daß bei einem fälligen Wechsel der Membran, welcher üblicherweise bzw. in der Praxis ca. alle zwei Wochen durchgeführt werden muß, oder bei einem ersten Einführen der Membran in die Membranpresse die Membran werkzeuglos manuell aus den Halteelementen lösbar ist und auch ohne Benutzung von zusätzlichem Werkzeug wieder festlegbar ist. Die Membran kann zum Festlegen zunächst frei von den erfindungsgemäßen Halteelementen in die Membranpresse eingelegt werden. Danach kann dann eine einzelne Bedienungsperson rundum nach und nach die Halteelemente mit dem Membranrand ohne Werkzeugeinsatz sehr schnell in Eingriff bringen. Hierdurch wird eine erhebliche Zeiteinsparung erzielt, bei der sich überraschenderweise gezeigt hat, daß der Membranwechsel mit den erfindungsgemäßen Halteelementen nur noch etwa ein Viertel der Zeit in Anspruch nimmt wie bei einer herkömmlichen Halterung mit einer Vielzahl von Schrauben, die mittels zusätzlichem Werkzeug, beispielsweise einem Schraubenschlüssel, gelöst bzw. angezogen werden müssen.Due to the inventive design of the holding elements is advantageously achieved that in a due change of the membrane, which usually or in practice about every two weeks must be performed, or in a first insertion of the membrane in the membrane press, the membrane without tools manually from the Retaining elements is releasable and can be fixed again without the use of additional tools. The membrane can initially be inserted into the membrane press to set it free of the holding elements according to the invention. Thereafter, then a single operator around little by little, the holding elements with the membrane edge without tools use very quickly engage. As a result, a considerable saving of time is achieved in which has surprisingly been found that the membrane change with the holding elements according to the invention takes only about a quarter of the time as in a conventional holder with a variety of screws using an additional tool, such as a wrench , must be solved or tightened.
Eine erste Weiterbildung der Membranpresse nach dem Anspruch 1 sieht vor, daß die Halteelemente einen Quersteg aufweisen, an dem beidseitig jeweils ein Klemmsteg angeordnet ist, wobei im Querschnitt gesehen die Klemmstege mit ihrem freien Ende von dem Quersteg weg gerichtet schräg aufeinander zu verlaufend orientiert sind, so daß eine zum Quersteg gegenüberliegende Öffnung gebildet ist, die sich in Richtung zum Quersteg konusartig erweitert, wobei der Klemmbolzen in einer Klemmlage in der Nähe der freien Enden zwischen der Membran und einer zur Klemmfläche gegenüberliegenden Anlagefläche angeordnet ist, so daß die Membran kraftschlüssig festgelegt ist, und wobei der Klemmbolzen aus der Klemmlage in Richtung zum Quersteg anhebbar ist, so daß die Membran gelöst ist.A first development of the membrane press according to
Eine dazu alternative Ausgestaltung sieht vor, daß die Halteelemente einen Quersteg aufweisen, der an seiner einen Seite unmittelbar mit dem Tragrahmen starr verbunden ist und an dessen anderer Seite ein Klemmsteg angeordnet ist, wobei im Querschnitt gesehen der Klemmsteg mit seinem freien Ende in Richtung von dem Quersteg weg schräg auf eine dem Klemmsteg zugewandte Klemmfläche des Tragrahmens zu verlaufend orientiert ist, so daß eine zum Quersteg gegenüberliegende Öffnung gebildet ist, die sich in Richtung zum Quersteg konusartig erweitert, wobei der Klemmbolzen in einer Klemmlage in der Nähe des freien Endes zwischen der Membran und einer zur Klemmfläche gegenüberliegenden Anlagefläche angeordnet ist, so daß wie Membran kraftschlüssig festgelegt ist, und wobei der Klemmbolzen aus der Klemmlage in Richtung zum Quersteg anhebbar ist, so daß die Membran gelöst ist.An alternative embodiment provides that the holding elements have a transverse web which is rigidly connected at its one side directly to the support frame and at the other side a clamping web is arranged, seen in cross-section of the clamping web with its free end in the direction of the Quersteg away obliquely oriented to a clamping web facing the clamping surface of the support frame to extend, so that a transverse web to the opposite opening is formed, which widens conically in the direction of the crosspiece, wherein the clamping bolt in a clamping position in the vicinity of the free end between the membrane and a bearing surface lying opposite the clamping surface is arranged, so that as a diaphragm is fixed non-positively, and wherein the clamping bolt from the clamping position in the direction of the crosspiece can be raised, so that the membrane is released.
Bei den beiden zuvor genannten vorteilhaften Ausgestaltung kann die Membran mit ihrem Rand leicht durch die Öffnung in das erfindungsgemäße Halteelement eingeführt werden, wobei der Klemmbolzen manuell von einer Bedienperson oder allein durch das Einführen des Membranrandes angehoben wird. Ist die Membran mit ihrem Rand hinreichend weit in das Halteelement eingeführt, kann die Bedienperson den Klemmbolzen loslassen, so daß dieser zwischen der Membran und der Anlagefläche an einem der Klemmstege zur Anlage kommt. Hierdurch wird die Membran kraftschlüssig an der Klemmfläche des dazu gegenüberliegenden Klemmsteges durch einen Selbstklemmeffekt des Klemmbolzens festgelegt. Die Bedienperson kann hierbei umlaufend die in einer bevorzugten Ausführung punktuell angreifenden Halteelemente, soweit die Halteelemente über den Umfang der Membran in Abständen verteilt angeordnet sind, mit dem Membranrand verbinden. Wird der Tragrahmen entlang einer Spannrichtung verfahren, bewegt sich der Klemmbolzen weiter in Richtung zur Öffnung, so daß die Membran kraftschlüssig hinreichend fest von dem Halteelement gehalten wird, wobei der Selbstklemmeffekt des Klemmbolzens verstärkt wird.In the two aforementioned advantageous embodiment, the membrane can be easily inserted with its edge through the opening in the holding element according to the invention, wherein the clamping bolt manually by an operator or solely by the insertion of the membrane edge is raised. If the membrane is inserted with its edge sufficiently far into the retaining element, the operator can release the clamping bolt, so that it comes to rest between the membrane and the contact surface on one of the clamping webs. As a result, the membrane is fixed non-positively on the clamping surface of the clamping bar opposite thereto by a self-clamping effect of the clamping bolt. In this case, the operator can circumferentially connect the holding elements, which are selectively applied in a preferred embodiment, as far as the holding elements are distributed over the circumference of the membrane at intervals, with the membrane edge. If the support frame is moved along a tensioning direction, the clamping bolt moves further in the direction of the opening, so that the diaphragm is held in a force-fitting manner sufficiently firmly by the retaining element, the self-clamping effect of the clamping bolt being reinforced.
Zum Lösen der Membran aus dem erfindungsgemäßen Halteelement wird der Tragrahmen entgegengesetzt verfahren, so daß sich die Membran entspannt. Danach kann die Bedienperson nun rundum den jeweiligen Klemmbolzen einfach aus der Klemmlage in Richtung zum Quersteg anheben, so daß die Membran leicht und ohne Benutzung eines zusätzlichen Werkzeugs aus jedem Halteelement lösbar ist. Dabei kann es zwar vorkommen, daß der Klemmbolzen in der entspannten Lage der Membran derart festliegt, daß dieser beispielsweise mittels eines leichten Schlages gelöst werden muß; jedoch ändert das nichts an der Tatsache, daß eine erhebliche Zeitersparnis erzielt wird, wenn die Membran gewechselt werden muß, da das Aufbringen eines leichten Schlages nicht so zeitraubend ist, wie es beispielsweise ein drehendes Lösen von Schrauben ist.To release the membrane from the holding element according to the invention, the support frame is moved opposite, so that relaxes the membrane. Thereafter, the operator can now just around the respective clamping bolt simply lift out of the clamping position in the direction of the crosspiece, so that the membrane is easily and without the use of an additional tool from each support member is releasable. It may happen that the clamping bolt in the relaxed position of the membrane is fixed so that it must be solved for example by means of a light impact; However, this does not change the fact that a considerable saving of time is achieved when the membrane has to be replaced, since the application of a light impact is not as time-consuming as, for example, a rotating loosening of screws.
Für Ausführungen der Membranpresse gemäß dem Anspruch 4 ist der Membranrand gezahnt oder gezackt ausgeführt, wobei die einzelnen Zähne bzw. Zacken an das schnallenartige Halteelement angepaßt sind. Hierbei muß die Bedienperson den Membranrand bzw. dessen Zähne oder Zacken einfach in das Gurtschloß bzw. das schnallenartige Element einführen, wobei eine kraftschlüssige Verbindung erreichbar ist.For embodiments of the membrane press according to
Vorteilhafterweise kann bei allen Ausgestaltungen der erfindungsgemäßen Halteelemente auf eine Lochung der Membran an ihrem Rand verzichtet werden, so daß eine Zerstörung der Membran, die beispielsweise durch von den Lochungen ausgehende Risse hervorgerufen werden kann, vermieden wird.Advantageously, in all embodiments of the retaining elements according to the invention can be dispensed with a perforation of the membrane at its edge, so that a destruction of the membrane, which can be caused for example by outgoing from the holes cracks, is avoided.
Damit die Membran hinreichend gleichmäßig festgehalten wird, angreifen die Halteelemente über den Umfang des Randbereiches verteilt an der Membran, und eine Halteelementreihe bilden. Hierzu kann der Tragrahmen umlaufend durchgehend oder in Abschnitte unterteilt ausgestaltet sein.So that the membrane is held sufficiently uniformly, the holding elements engage distributed over the circumference of the edge region on the membrane, and form a holding element row. For this purpose, the support frame can be designed circumferentially continuous or divided into sections.
Um zu erreichen, daß die Halteelemente zumindest zum Verbinden der Membran mit den Halteelementen flexibel sind, ist für die Ausführungen außer dem Anspruch 3 vorteilhaft vorgesehen, daß den Halteelementen Aufhängungselemente zugeordnet sind, die zwischen den Halteelementen und dem Tragrahmen angeordnet sind. Damit wird vorteilhaft erreicht, daß die Halteelemente in der entspannten Position der Membran nicht starr mit dem Tragrahmen verbunden sind, sondern dreidimensional beweglich sind, so daß sich eine noch leichtere Verbindung bzw. Einführung der Membran in die erfindungsgemäßen Halteelemente ergibt.In order to achieve that the holding elements are flexible at least for connecting the membrane to the holding elements, it is advantageously provided for the embodiments other than
Alternativ oder zusätzlich können den Halteelementen Federelemente zugeordnet sein, die zwischen dem Halteelement und dem Tragrahmen angeordnet sind. Hiermit wird eine über den Umfang der Membran gesehen besonders gleichmäßige Einleitung der Spannkraft in die Membran erreicht. Die Federelemente sind beispielsweise.als Schraubenfedern ausgestaltet.Alternatively or additionally, the holding elements may be associated with spring elements which are arranged between the holding element and the support frame. Hereby, a particularly uniform introduction of the clamping force into the membrane is achieved over the circumference of the membrane. The spring elements are beispiel.al coil springs.
Damit die Membran wirkungsvoll funktionieren kann, muß diese in ihrer Arbeitsposition derart gespannt sein, daß sie eine glatte Fläche bildet, damit ein hinreichend gutes Produktionsergebnis der Membranpresse bzw. des Laminators erzielt wird. Zweckmäßig im Sinne der Erfindung ist daher vorgesehen, daß dem Tragrahmen zumindest ein Verstellmittel zugeordnet ist, mit dem der Tragrahmen entlang der Spannrichtung verstellbar ist. Damit kann der Tragrahmen aus einer entspannten Position, in welcher die Membran leicht mit den Halteelementen verbindbar ist, in eine gespannte Position, in der die Membran in ihrer Fläche strammgezogen ist, verfahren werden.In order for the membrane to function effectively, it must be stretched in its working position so that it forms a smooth surface, so that a sufficiently good production result of the membrane press or the laminator is achieved. Appropriately in the context of the invention is therefore intended that the support frame is associated with at least one adjusting means with which the support frame along the clamping direction is adjustable. Thus, the support frame from a relaxed position in which the membrane is easily connectable to the holding elements, in a tensioned position in which the membrane is tightened in its surface, be moved.
Günstig im Sinne einer einfachen Ausführung ist, wenn das Verstellmittel manuell betätigbar ist, wobei das Verstellmittel beispielsweise als Spindel ausgeführt sein kann.Favorable in terms of a simple design is when the adjusting means is manually operable, wherein the adjusting means may be embodied for example as a spindle.
Zweckmäßig ist alternativ aber auch, wenn das Verstellmittel einen Kraftantrieb aufweist, wobei das Verstellmittel beispielsweise als Hydraulik- oder Pneumatikzylinder ausgeführt ist. Auch elektrische Verstellmittel sind denkbar.Appropriately, however, is also alternatively, if the adjusting means has a power drive, wherein the adjusting means is designed for example as a hydraulic or pneumatic cylinder. Also, electrical adjustment means are conceivable.
Für die Ausführungen mit Verstellmittel wird weiter vorgeschlagen, daß durch das Verstellmittel die Membran mit einer vorgebbaren Zugspannung beaufschlagbar ist, so daß die Membran stetig nachspannbar ist. Damit können in der Praxis mit der Zeit oder durch hohe Temperaturen auftretende Längungen der Membran selbsttätig ausgeglichen werden, wodurch immer für eine gewünschte glatte Lage der Membran gesorgt wird. Ist das Verstellmittel z.B. als Pneumatikzylinder zum Anheben des Tragrahmens ausgestaltet, kann dieses mit einer durch einen vorgebbaren Pneumatikdruck festlegbaren Vorspannung in Spannrichtung beaufschlagt werden, wodurch die Membran stetig nachgespannt wird.For the embodiments with adjusting means is further proposed that the membrane can be acted upon by the adjusting means with a predetermined tensile stress, so that the membrane is continuously re-tensioned. As a result, elongations of the membrane occurring in practice over time or due to high temperatures can be compensated automatically, thereby always ensuring a desired smooth position of the membrane. If the adjusting means is e.g. designed as a pneumatic cylinder for lifting the support frame, this can be acted upon by a definable by a predetermined pneumatic pressure bias in the clamping direction, whereby the membrane is constantly tightened.
Zur leichteren Verbindung des Randbereiches der Membran mit den jeweiligen Halteelementen ist vorteilhaft vorgesehen, daß die Aufhängungselemente, insbesondere mit ihrem Schraubenbolzen, bevorzugt in einer Längsrichtung des Tragrahmens verschieblich gelagert sind. Hierzu ist vorteilhaft ein Längsschlitz an einer Unterseite des Tragrahmens vorgesehen, in den die Aufhängungselemente z.B. durch geöffnete Stirnseiten des Tragrahmens eingeführt werden können. Zur Höhenverstellung und hinreichenden zugfesten Lagerung des Schraubenbolzens in dem Tragrahmen weist der Schraubenbolzen kopfseitig eine Mutter auf, der eine Unterlegscheibe zugeordnet sein kann.For easier connection of the edge region of the membrane with the respective holding elements is advantageously provided that the suspension elements, in particular with their bolts, are preferably mounted displaceably in a longitudinal direction of the support frame. For this purpose, a longitudinal slot is advantageously provided on an underside of the support frame, into which the suspension elements e.g. can be inserted through open end faces of the support frame. For height adjustment and sufficient tensile strength bearing of the bolt in the support frame, the bolt on the head side, a nut, which may be associated with a washer.
Der Randbereich der Membran ist in einer Ausgestaltung beispielhaft bezogen auf eine Horizontalebene senkrecht dazu über die Kanten einer Platte oder eines Rahmens spannbar, wodurch sich eine vertikale Spannrichtung ergibt. Die Kanten sind zweckmäßig zur Schonung der Membran abgerundet.In one embodiment, the edge region of the membrane can be tensioned perpendicularly over the edges of a plate or a frame, with reference to a horizontal plane, resulting in a vertical clamping direction. The edges are expediently rounded to protect the membrane.
Zur Reduzierung von Reibungseinflüssen kann der Randbereich der Membran bezogen auf die Horizontalebene aber auch in einem spitzen Winkel (0<α<90°) spannbar sein, wodurch sich eine entsprechend schräg verlaufende Spannrichtung ergibt.In order to reduce the influence of friction, the edge region of the membrane can also be tensioned at an acute angle (0 <α <90 °) with respect to the horizontal plane, resulting in a correspondingly inclined clamping direction.
Schließlich kann der Randbereich der Membran bezogen auf die Horizontalebene auch parallel zur Horizontalebene verlaufend spannbar sein, wodurch schädliche Reibungseinflüsse auf die Membran vermieden werden.Finally, the edge region of the membrane relative to the horizontal plane can also be tensioned running parallel to the horizontal plane, whereby harmful effects of friction on the membrane are avoided.
Die Erfindung schlägt für die Membranpresse weiter vor, daß unmittelbar über der Membran eine rahmen- oder plattenförmige Membranstütze angeordnet ist, daß unter der Membran randseitig umlaufend ein Dichtrahmen angeordnet ist, daß die Membranstütze mit der Membran einerseits und der Dichtrahmen andererseits in ihrem Abstand relativ zueinander verstellbar sind und daß die Membranstütze und der Dichtrahmen in einer Klemmposition gegeneinander verspannbar sind. Auf diese Weise können die Membranstütze mit der Membran einerseits und der Dichtrahmen andererseits relativ zueinander unter Einklemmung der Membran festgelegt werden. Zum Nachspannen oder Tauschen der Membran werden die Membranstütze und der Dichtrahmen aus ihrer Klemmposition auseinanderbewegt.The invention also proposes for the membrane press, that a frame-shaped or plate-shaped membrane support is arranged directly above the membrane, that under the membrane peripherally a sealing frame is arranged, that the membrane support with the membrane on the one hand and the sealing frame on the other hand in their distance relative to each other are adjustable and that the diaphragm support and the sealing frame are clamped in a clamping position against each other. In this way, the membrane support with the membrane on the one hand and the sealing frame on the other hand can be set relative to each other under entrapment of the membrane. To re-tension or replace the membrane, the membrane support and the sealing frame are moved apart from their clamping position.
In einer Weiterbildung dazu ist vorgesehen, daß als Mittel zum Verspannen von Membranstütze und Dichtrahmen gegeneinander mehrere über den Umfang der Membranpresse verteilt angeordnete, vertikale Spannstangen vorgesehen sind, die mit ihrem unteren Ende mit an dem Dichtrahmen vorgesehenen Haken in lösbaren Eingriff bringbar sind und die mittels je eines an ihrem oberen Ende vorgesehenen Spannhebels in Vertikalrichtung verstellbar und in einer Spannstellung festlegbar sind. Auf diese Weise werden eine einfache, aber zuverlässige Konstruktion und eine einfache Bedienbarkeit erreicht.In a further development, it is provided that as a means for clamping the diaphragm support and sealing frame against each other several distributed over the circumference of the membrane press arranged, vertical tie rods are provided which can be brought with its lower end provided with hooks on the sealing frame in detachable engagement and the means each one provided at its upper end clamping lever in the vertical direction adjustable and can be fixed in a clamping position. In this way, a simple but reliable construction and ease of use achieved.
Insgesamt wird somit durch die unterschiedlichen vorteilhaften Ausgestaltungen der Erfindung eine verbesserte Membranpresse zur Verfügung gestellt, bei der die Membran werkzeuglos lösbar und festlegbar ist. Damit ist der übliche Membranwechsel, der in der Praxis z.B. bei einem Laminator ca. alle zwei Wochen durchgeführt werden muß, in einer wesentlich kürzeren Zeit durchführbar, wobei sich überraschend herausgestellt hat, daß der Membranwechsel mit den vorstehend beschriebenen Halteelementen nur noch etwa ein Viertel der Zeit in Anspruch nimmt wie bei einer herkömmlichen Membranhalterung mit einer Vielzahl von Schrauben.Overall, an improved membrane press is thus provided by the different advantageous embodiments of the invention, in which the membrane is detachable and fixable without tools. Thus, the usual membrane change, which in practice is e.g. has to be carried out in a laminator approximately every two weeks, in a much shorter time feasible, which has surprisingly been found that the membrane change with the holding elements described above takes only about a quarter of the time as in a conventional membrane holder with a Variety of screws.

Fußseitig weist jedes Aufhängungselement 16 eine Öse 18 auf, die bevorzugt mit dem Schraubenbolzen 17 verschraubt ist. In der Öse 18 ist ein Ringelement 19 angeordnet. Das Ringelement 19 ist mit dem Halteelement 6 verbunden. In dem in
Das Halteelement 6 nach dem Ausführungsbeispiel gemäß Figur 1 weist einen Quersteg 23 auf, an dem beidseitig jeweils ein Klemmsteg 24 angeordnet ist.

Die Öffnung 27 erweitert sich in Richtung zum Quersteg 23 konusartig. Der Klemmbolzen 21 ist in einer Klemmlage 28 in der Nähe der freien Enden 26 zwischen der Membran 3 und einer zur Klemmfläche 22 gegenüberliegenden Anlagefläche 29 angeordnet, so daß die Membran 3 kraftschlüssig festgelegt ist.

Der Tragrahmen 2 ist hier deutlich sichtbar unmittelbar mit den Haltelementen 6, von denen hier in der Schnittdarstellung nur eines sichtbar ist, verbunden. Das Halteelement 6 besitzt hier einen Klemmsteg 24, der im Abstand zu einer nach außen, d. h. zum Klemmsteg 24 hin weisenden Klemmfläche 25 des Tragprofils 2 verläuft.

Zur Erzeugung einer Spannkraft für die Membran 3 dient das Verstellmittel 8, das in Form einer Gewindespindel ausgeführt ist. Das spindelförmige Verstellmittel 8 verläuft von oben kommend durch das Tragprofil 2 hindurch. Mit der Unterseite des Tragprofils 2 ist eine Gewindemutter 10 verdrehfest verbunden, zweckmäßig verschweißt. Am oberen Ende des Verstellmittels 8, das oberhalb eines plattenförmigen starren Bauteils 11 der Membranpresse 1 liegt, ist ein Sechskant 15 verdrehfest angebracht, dessen Durchmesser so groß ist, daß er im Unterschied zum spindelförmigen Verstellmittel 8 nicht durch das starre Bauteil 11 hindurchpaßt. Durch Verdrehen dieses Sechskants 15 wird das spindelförmige Verstellmittel 8 verdreht, wodurch sich im Zusammenwirken mit der Gewindemutter 10 entsprechend der Drehrichtung entweder eine Bewegung des Tragrahmens 2 nach oben oder eine Bewegung des Tragrahmens 2 nach unten und damit verbunden ein Spannen oder ein Entspannen der Membran 3 ergibt.To generate a clamping force for the
