Definitions

  • the present invention relates generally to staircase shims (tolerance compensating sheeting) having a thickness adjustable by delamination, as mechanical structure adjusters.
  • the invention relates to a laminated intermediate layer (tolerance compensation layer film) with a thickness which can be adapted by layer cleavage, this product comprising an optionally alternating layering of film elements (flat material sheet) and optionally of layers of an adhesive.
  • peelable materials as washers in complex mechanical constructions is widespread, especially in aviation. These designs can comprise several hundred, even several thousand, parts, each of which has dimensional tolerances. The sum of the tolerances creates games which in some cases can be considerable and several millimeters and which must be balanced to allow the mechanical constructions to perform their functions properly.
  • liners adjustment elements
  • These peelable shims consist of thin lamellae, which are stacked and glued together so that they form a greater or lesser total thickness, and which are machined so that they adapt to the outer contour of the device to be adjusted. The adjustment is made by reducing the thickness of the spacer (shim) by peeling off one or more of these layers and inserting the shim (shim) at the point where the clearance was detected.
  • EP 667233 A describes peelable intermediate layers (adjusting elements) which comprise a series of foil elements (flat material sheets), between which adhesive layers are respectively inserted.
  • the film elements (flat material sheet) are made of metal or optionally of plastic.
  • No. 4,526,641 A describes an intermediate layer (shim) which consists of a layer of thermosetting film elements (flat sheet) which are joined together by means of an adhesive of the same nature and which are characterized by a certain intralaminar cohesive force.
  • DE 602 08 922 T2 relates to a laminate (an intermediate layer) with adjustable thickness by peeling, method of manufacture and application to the formation of shims.
  • the product comprises an alternating stratification of Flat sheets (sheets) and layers of an adhesive, each sheet (sheet) having an internal resistance to tearing and wherein each layer of adhesive bonds two adjoining sheet sheets (sheets) of the sheet to a binding force that is less than the resistance the flat material sheet (foil elements) against tearing, which leads to the fact that here the sheet of flat material (the film elements) can be released from the layering without it tearing.
  • This product is essentially characterized in that here the flat material sheet (the film elements) is formed essentially of woven fibers, and in that here the flat material sheet (the film elements) of each pair of flat sheet adjacent to a same, common layer of adhesive (the Sheeting elements) is impregnated throughout its thickness with a mass of adhesive which is integral with the common layer of adhesive.
  • the flat material sheet the film elements
  • the Sheeting elements the flat material sheet of each pair of flat sheet adjacent to a same, common layer of adhesive
  • step-shaped or step-shaped intermediate layers which eliminates the above-described difficulties with non-parallel gaps.
  • the solution of the above object consists in a first embodiment in a laminated intermediate layer for tolerance compensation with a plurality of individual films, which is characterized in that
  • the respective individual film is separated into individual rib-shaped surface elements, the separation of the surface elements is perpendicular to the plane of the films and wherein
  • the underside of the lowermost individual film is laminated over its entire surface with a cover film which extends in the form of a spine to the top of the top single film with which it is glued over the entire surface or part of the surface.
  • Fig. 1 describes the underside of a laminated intermediate layer for tolerance compensation with exemplary positioned holes 2a, 2b, 2b, which are divided into individual stair-shaped surface elements 3a, 3b, 3c, 3d, 3b, 3f, 3g, 3h, 3i and 3j along the dashed lines can be or is present in one piece.
  • FIG. 2 shows the individual surface elements 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i and 4j. These are fastened in separate blocks on the basis of FIG. 1 or subsequently cut out of the individual foils. Accordingly, the separation of the surface elements 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i and 4j is perpendicular to the plane of the film elements.
  • the films / surfaces elements 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i and 4j are laminated with a cover film 5, which is in the form of a spine from the underside of the surface elements 3a , 3b, 3c, 3d, 3b, 3f, 3g, 3h, 3i and 3j extends to the top of the top single film with which it is bonded over the entire surface or part of the surface.
  • FIG. 4 shows the book-like embodiment of the laminated intermediate layer for tolerance compensation by the black boundary line and the individual foils.
  • FIG. 5 shows an enlargement of the portion V of FIG. 4 in which the illustrated regions of the foils 3f and 4f are covered by the cover foil 5.
  • the cover sheet 5 stabilizes the film stack.
  • the cover film is removed from the upper side of the individual foils 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i and 4j, then the individual surface elements of the individual foils can be removed and, for example, a step-shaped or stepped arrangement can be achieved. After removal, for example by peeling or peeling off, a step-shaped or stepped intermediate layer can thus be obtained.
  • the cover sheet 5 can then be applied again to the uppermost layer of the individual foils 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i and 4 and adhesively bonded thereto.
  • the individual films of the laminated intermediate layer according to the invention including tolerance compensation, have a thickness of 0.1 mm to 0.025 mm. However, it is also possible for any other thicknesses of the individual foils to be provided, wherein these need not necessarily all have the same thickness.
  • the individual films it is particularly preferred to bond the individual films to one another and to the cover film 5 with the uppermost and / or the lowermost individual film over the whole area or part of the area.
  • the full-surface bonding between the surface elements can be disadvantageous when the intermediate layers (tolerance compensation liners) are inserted between two curved components.
  • the full-surface bonding is occasionally disadvantageous when peeling off individual film elements, since tools generally have to be used here. It is also disadvantageous in part that with metallic intermediate layers (tolerance compensation liners) the stripped layers curl up and immediately become scrap and thus pose a risk of having the entire intermediate layer rejected if one deducts too much.
  • This disadvantage can be overcome according to the invention by providing an intermediate layer with a total thickness of layering of film elements that can be adapted by layer separation, each film element consisting of a film of constant thickness and the film elements of the same or different Thickness exist, and the film elements 3e, 3g and 4e and 4j are partially or completely connected via their end faces with an adhesive (spine gluing).
  • a further advantageous embodiment of these intermediate layers with different, but also with the same thicknesses of the film elements can be achieved by providing products with adhesive only in subregions of the sheet elements lying one on top of the other.
  • An application of the surface elements 4a to 4 on a flexible bendable base plate as in Figure 1 may prove advantageous for curved surfaces of the modules.
  • the partial bonding allows a flexible radius design for curved surfaces, if in applications two curved surfaces must be kept at a distance.
  • different types of materials can be combined with a variety of advantageous properties for the application, such as: avoiding contact corrosion, introducing sliding layers, integrating thicker sheet elements (intermediate material sheets), the stiffness and higher compressive strengths bring and cost advantages by the number of layers is reduced.
  • the process for providing the film elements with adhesive by spraying, by applying by hand by means of a roller, by printing on an "offset" type machine or by immersion.
  • the adhesive is a synthetic rubber and / or a resin, for example an optionally water-based acrylate, epoxy, phenolic, vinylester or polyvinyl resin, which holds the film elements together by a polymerization process.
  • the rubber and / or the resin may be provided with additives to form the adhesive, these additives being hardening and / or diluting agents for changing the viscosity of the adhesive.
  • the adhesive may constitute 40% to 60% of the volume of the product before the polymerization process.
  • the resin may be provided with additives to form the adhesive, these additives being hardening and / or diluting agents for changing the viscosity of the adhesive.
  • the adhesion of adjoining film elements is reduced by increasing the amount of the diluent in proportion to the amount of resin in the adhesive.
  • the additive can make up more than 50% of the volume of the adhesive before the polymerization process.
  • the inventive intermediate layer (tolerance compensation layer film) according to the present invention is a time and cost-optimized alternative to known intermediate layers of small thickness for non-parallel gaps.
  • the production of intermediate layers (tolerance compensation layer films) of the same total thickness depends on the number of individual film elements (flat material sheets). The more foil elements (flat material sheets) are contained with the same total layer thickness, the thinner must accordingly a foil elements (flat material sheet) are performed, which at a smaller thickness of individual foil elements (flat material sheets) leads to higher costs.
  • the film elements are particularly preferably metallic foils, polymer foils, fiber composite materials, woven fabrics and / or nonwovens made of fibers, essentially glass, carbon, ceramic or aramid fibers or a mixture of different materials with one another. These can be combined with each other as desired. It may be preferable to equip the intermediate layers with at least two types of film elements of different thickness. Particularly preferred according to the present invention, the thickness of a first type of film elements to the thickness of a second type of film elements in the ratio of 10 to 2 to 10 to 7, in particular 10 to 5, that is, the individual film elements is half as thick as the other foil elements.

Description

Treppenförmiae Zwischenlaae (Toleranzausaleich-Schichtfolie)  Treppenförmiae Zwischenlaae (Toleranzausaleich-Schichtfolie)
Die vorliegende Erfindung betrifft im Allgemeinen treppenförmige Zwischenlagen (Toleranzausgleich-Schichtfolien), mit einer durch Schichtspaltung anpassbaren Dicke, als Einstellelemente für mechanische Konstruktionen. The present invention relates generally to staircase shims (tolerance compensating sheeting) having a thickness adjustable by delamination, as mechanical structure adjusters.
Im Einzelnen betrifft die Erfindung in einer ersten Ausgestaltung eine laminierte Zwischenlage (Toleranzausgleich-Schichtfolie) mit einer durch Schichtspaltung anpassbaren Dicke, wobei dieses Erzeugnis eine gegebenenfalls abwechselnde Schichtung von Folienelemente (Flachmaterialbogen) und gegebenenfalls von Schichten eines Klebstoffs umfasst. More particularly, in a first embodiment, the invention relates to a laminated intermediate layer (tolerance compensation layer film) with a thickness which can be adapted by layer cleavage, this product comprising an optionally alternating layering of film elements (flat material sheet) and optionally of layers of an adhesive.
Der Einsatz dieser so genannten abziehbaren Materialien als Unterlegscheiben in komplexen mechanischen Konstruktionen ist weit verbreitet, insbesondere in der Luftfahrt. Diese Konstruktionen können mehrere hundert, ja sogar mehrere tausend Teile umfassen, von denen jedes Maßtoleranzen aufweist. Die Summe der Toleranzen erzeugt Spiele, die in manchen Fällen beträchtlich sein und mehrere Millimeter betragen können und die ausgeglichen werden müssen, um es den mechanischen Konstruktionen zu erlauben, ihre Funktionen ordnungsgemäß zu erfüllen. Zu diesem Zweck werden Zwischenlagen (Einstellelemente) aus metallischen oder polymeren Materialien verwendet, die in den meisten Fällen abziehbar sind. Diese abziehbaren Zwischenlagen (Ausgleichsscheiben) bestehen aus dünnen Lamellen, die übereinander geschichtet und so miteinander verklebt sind, dass sie eine mehr oder weniger große Gesamtdicke bilden, und die so bearbeitet sind, dass sie sich an die Außenkontur der zu justierenden Einrichtung anpassen. Die Einstellung erfolgt durch Verringerung der Dicke der Zwischenlage (Ausgleichsscheibe), indem eine oder mehrere dieser Schichten abgezogen werden und die Zwischenlage (Ausgleichsscheibe) an der Stelle eingesetzt wird, an der das Spiel festgestellt wurde. The use of these so-called peelable materials as washers in complex mechanical constructions is widespread, especially in aviation. These designs can comprise several hundred, even several thousand, parts, each of which has dimensional tolerances. The sum of the tolerances creates games which in some cases can be considerable and several millimeters and which must be balanced to allow the mechanical constructions to perform their functions properly. For this purpose, liners (adjustment elements) of metallic or polymeric materials are used, which are removable in most cases. These peelable shims (shims) consist of thin lamellae, which are stacked and glued together so that they form a greater or lesser total thickness, and which are machined so that they adapt to the outer contour of the device to be adjusted. The adjustment is made by reducing the thickness of the spacer (shim) by peeling off one or more of these layers and inserting the shim (shim) at the point where the clearance was detected.
EP 667233 A beschreibt abziehbare Zwischenlagen (Einstellelemente), die eine Reihe von Folienelemente (Flachmaterialbogen) umfasst, zwischen denen jeweils Klebstoffschichten eingefügt sind. Die Folienelemente (Flachmaterialbogen) sind aus Metall oder gegebenenfalls aus Kunststoff. EP 667233 A describes peelable intermediate layers (adjusting elements) which comprise a series of foil elements (flat material sheets), between which adhesive layers are respectively inserted. The film elements (flat material sheet) are made of metal or optionally of plastic.
US 4526641 A beschreibt eine Zwischenlage (Einstellscheibe), die aus einer Schichtung von wärmeaushärtenden Folienelemente (Flachmaterialbogen) besteht, die mittels eines Klebstoffs gleicher Beschaffenheit miteinander verbunden sind und die durch eine gewisse intralaminare Kohäsionskraft gekennzeichnet sind. No. 4,526,641 A describes an intermediate layer (shim) which consists of a layer of thermosetting film elements (flat sheet) which are joined together by means of an adhesive of the same nature and which are characterized by a certain intralaminar cohesive force.
DE 602 08 922 T2 betrifft einen Schichtstoff (eine Zwischenlage) mit einstellbarer Dicke durch Abschälen, Verfahren zur Herstellung und Anwendung zur Bildung von Ausgleichsscheiben. Zu diesem Zwecke umfasst das Erzeugnis eine abwechselnde Schichtung von Flachmaterialbogen (Folienelemente) und von Schichten eines Klebstoffs, wobei jeder Flachmaterialbogen (Folienelemente) einen inneren Widerstand gegen das Zerreißen aufweist und wobei jede Schicht von Klebstoff zwei aneinander angrenzende Flachmaterialbogen (Folienelemente) der Schichtung mit einer Bindungskraft verbindet, die geringer ist, als der Widerstand der Flachmaterialbogen (Folienelemente) gegen das Zerreißen, was dazu führt, dass hier der Flachmaterialbogen (die Folienelemente) von der Schichtung gelöst werden kann, ohne dass er zerreißt. Dieses Erzeugnis ist im Wesentlichen dadurch gekennzeichnet, dass hier der Flachmaterialbogen (die Folienelemente) im Wesentlichen aus Webfasern gebildet wird, und dadurch, dass hier der Flachmaterialbogen (die Folienelemente) eines jeden Paares von an eine selbe, gemeinsame Schicht von Klebstoff angrenzenden Flachmaterialbogen (die Folienelemente) auf seiner gesamten Dicke mit einer Masse von Klebstoff getränkt ist, die mit der gemeinsamen Schicht von Klebstoff eine Einheit bildet. Insoweit wird in vollem Umfang auf die Offenbarung dieses Dokuments Bezug genommen. DE 602 08 922 T2 relates to a laminate (an intermediate layer) with adjustable thickness by peeling, method of manufacture and application to the formation of shims. For this purpose, the product comprises an alternating stratification of Flat sheets (sheets) and layers of an adhesive, each sheet (sheet) having an internal resistance to tearing and wherein each layer of adhesive bonds two adjoining sheet sheets (sheets) of the sheet to a binding force that is less than the resistance the flat material sheet (foil elements) against tearing, which leads to the fact that here the sheet of flat material (the film elements) can be released from the layering without it tearing. This product is essentially characterized in that here the flat material sheet (the film elements) is formed essentially of woven fibers, and in that here the flat material sheet (the film elements) of each pair of flat sheet adjacent to a same, common layer of adhesive (the Sheeting elements) is impregnated throughout its thickness with a mass of adhesive which is integral with the common layer of adhesive. In that regard, reference is made in its entirety to the disclosure of this document.
Von der Firma Jicey und Lameco werden Zwischenlagen (Toleranzausgleichs-Schichtfolien) vorgeschlagen, die farblich unterscheidbare Folienelemente (Flachmaterialbogen) zweier verschiedener Dicken aufweisen. The companies Jicey and Lameco propose intermediate layers (tolerance compensation layer films) which have color-differentiable film elements (flat material sheets) of two different thicknesses.
Dem vorgenannten Stand der Technik ist gemeinsam, dass die einzelnen Folienelemente (Flachmaterialbogen), egal ob diese aus Metall, Polymerfolie oder einem Gewebe bestehen, in einem gegebenen System über die gesamte Fläche die gleiche Dicke aufweisen. Die Kombination einer Vielzahl von Folienelemente (Flachmaterialbogen) einer ersten Dicke mit einer Vielzahl von Folienelemente (Flachmaterialbögen) einer zweiten Dicke ist nur mit erheblichem Kostenaufwand herstellbar. Bei schrägen Spalten können diese jedoch nur unzureichend gleichförmig ausgeglichen werden. Common to the aforementioned prior art is that the individual film elements (flat material sheets), whether they are made of metal, polymer film or a fabric, have the same thickness over the entire area in a given system. The combination of a multitude of foil elements (flat material sheet) a first thickness with a plurality of film elements (flat material sheets) of a second thickness can be produced only at considerable expense. In oblique columns, however, these can be compensated only insufficiently uniform.
In diesem Zusammenhang ist es eine erste Aufgabe der Erfindung, treppenförmige oder stufenförmige Zwischenlagen (Toleranzausgleich- Schichtfolie) vorzuschlagen, die die oben beschriebenen Schwierigkeiten bei nicht parallelen Spalten beseitigt. In this connection, it is a first object of the invention to propose step-shaped or step-shaped intermediate layers (tolerance compensation layer film) which eliminates the above-described difficulties with non-parallel gaps.
Die Lösung der vorgenannten Aufgabe besteht in einer ersten Ausführungsform in einer laminierte Zwischenlage zum Toleranzausgleich mit mehreren Einzelfolien, die dadurch gekennzeichnet ist, dass The solution of the above object consists in a first embodiment in a laminated intermediate layer for tolerance compensation with a plurality of individual films, which is characterized in that
die jeweilige Einzelfolie in einzelne rippenförmigen Flächenelemente getrennt ist, die Trennung der Flächenelemente senkrecht zu der Ebene der Folien verläuft und wobei the respective individual film is separated into individual rib-shaped surface elements, the separation of the surface elements is perpendicular to the plane of the films and wherein
die Unterseite der untersten Einzelfolie ganzflächig mit einer Deckfolie laminiert ist, die sich in Form eines Buchrückens bis auf die Oberseite der obersten Einzelfolie erstreckt mit der sie ganzflächig oder teilflächig verklebt ist. the underside of the lowermost individual film is laminated over its entire surface with a cover film which extends in the form of a spine to the top of the top single film with which it is glued over the entire surface or part of the surface.
Fig. 1 beschreibt die Unterseite einer laminierten Zwischenlage zum Toleranzausgleich mit beispielhaft positionierten Bohrungen 2a, 2b, 2b , die in einzelne treppenförmige Flächenelemente 3a, 3b, 3c, 3d, 3b, 3f, 3g, 3h, 3i und 3j entlang der gestrichelten Linien unterteilt sein kann oder auch einstückig vorliegt. In der Fig. 2 sind die einzelnen Flächenelemente 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i und 4j dargestellt. Diese werden in getrennten Blöcken auf der Basis gemäß Fig. 1 befestigt oder im Nachhinein aus den einzelnen Folien herausgeschnitten. Dementsprechend verläuft die Trennung der Flächenelemente 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i und 4j senkrecht zu der Ebene der Folienelemente. Fig. 1 describes the underside of a laminated intermediate layer for tolerance compensation with exemplary positioned holes 2a, 2b, 2b, which are divided into individual stair-shaped surface elements 3a, 3b, 3c, 3d, 3b, 3f, 3g, 3h, 3i and 3j along the dashed lines can be or is present in one piece. FIG. 2 shows the individual surface elements 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i and 4j. These are fastened in separate blocks on the basis of FIG. 1 or subsequently cut out of the individual foils. Accordingly, the separation of the surface elements 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i and 4j is perpendicular to the plane of the film elements.
In der Fig. 3 wird dargestellt, dass die Folien/Flächen Elemente 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i und 4j mit einer Deckfolie 5 laminiert sind, die sich in Form eines Buchrückens von der Unterseite der Flächenelemente 3a, 3b, 3c, 3d, 3b, 3f, 3g, 3h, 3i und 3j bis auf die Oberseite der obersten Einzelfolie erstreckt, mit der sie ganzflächig oder teilflächig verklebt ist. 3, it is shown that the films / surfaces elements 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i and 4j are laminated with a cover film 5, which is in the form of a spine from the underside of the surface elements 3a , 3b, 3c, 3d, 3b, 3f, 3g, 3h, 3i and 3j extends to the top of the top single film with which it is bonded over the entire surface or part of the surface.
In der Fig. 4 wird die buchmäßige Ausgestaltung der laminierten Zwischenlage zum Toleranzausgleich durch die schwarze Begrenzungslinie und die einzelnen Folien dargestellt. Die Fig. 5 stellt eine Vergrößerung des Abschnitts V der Fig. 4 dar, in welchem die dargestellten Bereiche der Folien 3f und 4f durch die Deckfolie 5 bedeckt ist. Die Deckfolie 5 stabilisiert die Folienstapel. FIG. 4 shows the book-like embodiment of the laminated intermediate layer for tolerance compensation by the black boundary line and the individual foils. FIG. 5 shows an enlargement of the portion V of FIG. 4 in which the illustrated regions of the foils 3f and 4f are covered by the cover foil 5. The cover sheet 5 stabilizes the film stack.
Wird die Deckfolie von der Oberseite der Einzelfolien 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i und 4j entfernt, so können die einzelnen Flächenelemente der Einzelfolien entfernt und so beispielsweise eine stufenförmige oder treppenförmige Anordnung erreicht werden. Nach dem Entfernen, beispielsweise durch Abschälen oder abziehen, kann so eine treppenförmige oder stufenförmige Zwischenlage erhalten werden. Zur Montage kann dann die Deckfolie 5 wieder auf die oberste Lage der Einzelfolien 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i und 4 aufgebracht und damit verklebt werden. Die Einzelfolien der erfindungsgemäßen laminierten Zwischenlage samt Toleranzausgleich weisen dabei eine Dicke von 0,1 mm bis 0,025 mm auf. Es können aber auch beliebige andere Dicken der Einzelfolien bereitgestellt werden, wobei diese nicht notwendigerweise alle die gleiche Dicke aufweisen müssen. If the cover film is removed from the upper side of the individual foils 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i and 4j, then the individual surface elements of the individual foils can be removed and, for example, a step-shaped or stepped arrangement can be achieved. After removal, for example by peeling or peeling off, a step-shaped or stepped intermediate layer can thus be obtained. For assembly, the cover sheet 5 can then be applied again to the uppermost layer of the individual foils 4a, 4b, 4c, 4d, 4f, 4g, 4h, 4i and 4 and adhesively bonded thereto. The individual films of the laminated intermediate layer according to the invention, including tolerance compensation, have a thickness of 0.1 mm to 0.025 mm. However, it is also possible for any other thicknesses of the individual foils to be provided, wherein these need not necessarily all have the same thickness.
Besonders bevorzugt im Sinne der vorliegenden Erfindung ist es, die Einzelfolien untereinander und die Deckfolie 5 mit der obersten und/oder der untersten Einzelfolie ganzflächig oder teilflächig zu verkleben. For the purposes of the present invention, it is particularly preferred to bond the individual films to one another and to the cover film 5 with the uppermost and / or the lowermost individual film over the whole area or part of the area.
In der Praxis stellt sich häufig heraus, dass die vollflächige Verklebung zwischen den Flächenelementen von Nachteil sein kann, wenn die Zwischenlagen (Toleranzausgleich-Zwischenlagen) zwischen zwei gekrümmten Bauteilen eingesetzt werden. Die vollflächige Verklebung ist darüber hinaus gelegentlich beim Abschälen einzelner Folienelemente von Nachteil, da hier in der Regel Werkzeug benutzt werden muss. Weiterhin nachteilig ist teilweise, dass bei metallischen Zwischenlagen (Toleranzausgleich-Zwischenlagen) die abgezogenen Lagen sich zusammenrollen und sofort zu Ausschuss werden und somit ein Risiko darstellen, die gesamte Zwischenlage Ausschuss werden zu lassen, wenn man zu viel abzieht. In practice, it often turns out that the full-surface bonding between the surface elements can be disadvantageous when the intermediate layers (tolerance compensation liners) are inserted between two curved components. In addition, the full-surface bonding is occasionally disadvantageous when peeling off individual film elements, since tools generally have to be used here. It is also disadvantageous in part that with metallic intermediate layers (tolerance compensation liners) the stripped layers curl up and immediately become scrap and thus pose a risk of having the entire intermediate layer rejected if one deducts too much.
Dieser Nachteil kann erfindungsgemäß dadurch überwunden werden, dass man eine Zwischenlage mit einer durch Schichttrennung anpassbaren Gesamtdicke einer Schichtung von Folienelementen bereitstellt, wobei jedes Folienelement aus einer Folie konstanter Dicke besteht und die Folienelemente aus gleichen oder unterschiedlichen Dicken bestehen, und die Folienelemente 3e, 3g und 4e und 4j teilweise oder vollständig über ihre Stirnflächen mit einem Klebstoff verbunden sind (Buchrückenverklebung) . This disadvantage can be overcome according to the invention by providing an intermediate layer with a total thickness of layering of film elements that can be adapted by layer separation, each film element consisting of a film of constant thickness and the film elements of the same or different Thickness exist, and the film elements 3e, 3g and 4e and 4j are partially or completely connected via their end faces with an adhesive (spine gluing).
Eine weitere vorteilhafte Ausgestaltung dieser Zwischenlagen mit unterschiedlichen, aber auch mit gleichen Dicken der Folienelemente kann erzielt werden, indem Produkte nur in Teilbereichen der flächig aufeinander liegenden Folienelemente mit Klebstoff versehen werden. A further advantageous embodiment of these intermediate layers with different, but also with the same thicknesses of the film elements can be achieved by providing products with adhesive only in subregions of the sheet elements lying one on top of the other.
Allen Verklebungsarten ist gemein, dass sie wiederlösbar beziehungsweise spaltbar sind. All types of bonding have in common that they are redissolvable or fissile.
Eine Aufbringung der Flächenelemente 4a bis 4 auf eine flexible krümmbare Grundplatte wie in Figur 1 kann sich vorteilhaft für gekrümmte Flächen der Baugruppen erweisen. Zudem ermöglicht die teilweise Verklebung eine flexible Radiengestaltung für kurvige Oberflächen, sofern in Applikationen zwei gekrümmte Flächen auf Abstand gehalten werden müssen. Ebenso können unterschiedliche Materialarten verbunden werden mit unterschiedlichsten vorteilhaften Eigenschaften für die Anwendung, als da wären : Vermeidung von Kontaktkorrosion, Einbringen von Gleitschichten, Integrieren von dickeren Folienelemente (Zwischenmaterialbögen), die Steifigkeit und höhere Druckfestigkeiten einbringen und Kosten vorteile bieten, indem die Anzahl von Schichten verringert wird. An application of the surface elements 4a to 4 on a flexible bendable base plate as in Figure 1 may prove advantageous for curved surfaces of the modules. In addition, the partial bonding allows a flexible radius design for curved surfaces, if in applications two curved surfaces must be kept at a distance. Likewise, different types of materials can be combined with a variety of advantageous properties for the application, such as: avoiding contact corrosion, introducing sliding layers, integrating thicker sheet elements (intermediate material sheets), the stiffness and higher compressive strengths bring and cost advantages by the number of layers is reduced.
Besonders die Erhöhung der Drucksteifigkeit in einer Zwischenlage ohne soliden, dickeren Kern zu erreichen, kann sehr vorteilhaft sein, beispielsweise aus einem Aufbau vieler Schichten in Kombination mit einigen wenigen dünnen, zum Beispiel 2mm = sechs mal 0,3mm plus zweimal 0,1mm; da dann die Konstruktion der Zwischenlage keinen Mindestabstand in der Höhe des soliden Anteils einkalkulieren muss. So kann platzsparend aber drucksteif vollgeschichtet konstruiert werden. Gerade in der Verbesserung von bestehenden Konstruktionen - wo beispielsweise noch zu schleifende Distanzelemente vorgesehen sind - , wo nachträglich Toleranz-Zwischenlagen eingebracht werden sollen, kann das von Platz sparendem Vorteil sein. In particular, increasing the compressive rigidity in an intermediate layer without achieving a solid, thicker core can be very advantageous, for example, from a construction of many layers in combination with a few thin, for example 2mm = six times 0.3mm plus two times 0.1mm; because then the construction of the intermediate layer must take into account no minimum distance in the amount of the solid share. So space-saving but pressure-resistant vollgeschichtet be constructed. Especially in the improvement of existing constructions - where, for example, still to be grounded spacers are provided - where subsequently tolerance liners are to be introduced, this can be of space-saving advantage.
Gemäß einer vorteilhaften Ausgestaltung des Verfahrens kann der Vorgang zum Versehen der Folienelemente mit Kleber durch Zerstäuben, durch Aufbringen per Hand mittels einer Walze, durch Bedrucken auf einer Maschine vom Typ "Offset" oder durch Eintauchen erfolgen. According to an advantageous embodiment of the method, the process for providing the film elements with adhesive by spraying, by applying by hand by means of a roller, by printing on an "offset" type machine or by immersion.
In einer erfindungsgemäßen Ausführungsform handelt es sich bei dem Klebstoff um einen synthetischen Kautschuk und/oder um ein Harz, beispielsweise um ein gegebenenfalls wasserbasiertes Acrylat-, Epoxid-, Phenol-, Vinylester- oder Polyvinylharz, der/das die Folienelemente durch einen Polymerisationsvorgang zusammenhält. In one embodiment of the invention, the adhesive is a synthetic rubber and / or a resin, for example an optionally water-based acrylate, epoxy, phenolic, vinylester or polyvinyl resin, which holds the film elements together by a polymerization process.
Gemäß einer vorteilhaften Ausgestaltung des erfindungsgemäßen Erzeugnisses kann der Kautschuk und/oder das Harz mit Zusätzen versehen werden, um den Klebstoff zu bilden, wobei es sich bei diesen Zusätzen um Härte- und/oder Verdünnungsmittel zur Änderung der Viskosität des Klebstoffs handelt. Gemäß einer vorteilhaften Ausgestaltung des erfindungsgemäßen Erzeugnisses kann der Klebstoff 40% bis 60% des Volumens des Erzeugnisses vor dem Polymerisationsvorgang ausmachen. According to an advantageous embodiment of the product according to the invention, the rubber and / or the resin may be provided with additives to form the adhesive, these additives being hardening and / or diluting agents for changing the viscosity of the adhesive. According to an advantageous embodiment of the product according to the invention, the adhesive may constitute 40% to 60% of the volume of the product before the polymerization process.
Gemäß einer vorteilhaften Ausgestaltung des erfindungsgemäßen Erzeugnisses kann das Harz mit Zusätzen versehen werden, um den Klebstoff zu bilden, wobei es sich bei diesen Zusätzen um Härte- und/oder Verdünnungsmittel zur Änderung der Viskosität des Klebstoffs handelt. According to an advantageous embodiment of the product according to the invention, the resin may be provided with additives to form the adhesive, these additives being hardening and / or diluting agents for changing the viscosity of the adhesive.
Gemäß einer vorteilhaften Ausgestaltung des erfindungsgemäßen Erzeugnisses wird die Haftung aneinander angrenzender Folienelemente (Flachmaterialbogen) durch Erhöhung der Menge des Verdünnungsmittels im Verhältnis zur Menge des Harzes im Klebstoff verringert. According to an advantageous embodiment of the product according to the invention, the adhesion of adjoining film elements (flat material sheet) is reduced by increasing the amount of the diluent in proportion to the amount of resin in the adhesive.
Gemäß einer vorteilhaften Ausgestaltung des erfindungsgemäßen Erzeugnisses kann der Zusatz mehr als 50% des Volumens des Klebstoffs vor dem Polymerisationsvorgang ausmachen. According to an advantageous embodiment of the product according to the invention, the additive can make up more than 50% of the volume of the adhesive before the polymerization process.
Die erfindungsgemäße Zwischenlage (Toleranzausgleich-Schichtfolie) gemäß der vorliegenden Erfindung ist eine zeit- und kostenoptimierte Alternative zu bekannten Zwischenlagen geringer Dicke für nichtparallele Spalte. Naturgemäß ist die Herstellung von Zwischenlagen (Toleranzausgleich-Schichtfolien) gleicher Gesamtdicke von der Anzahl der einzelnen Folienelemente (Flachmaterialbögen) abhängig. Je mehr Folienelemente (Flachmaterialbögen) bei gleicher Gesamtschichtdicke enthalten sind, desto dünner muss entsprechend eine Folienelemente (Flachmaterialbogen) ausgeführt werden, was bei geringerer Dicke der einzelnen Folienelemente (Flachmaterialbögen) zu höheren Kosten führt. The inventive intermediate layer (tolerance compensation layer film) according to the present invention is a time and cost-optimized alternative to known intermediate layers of small thickness for non-parallel gaps. Naturally, the production of intermediate layers (tolerance compensation layer films) of the same total thickness depends on the number of individual film elements (flat material sheets). The more foil elements (flat material sheets) are contained with the same total layer thickness, the thinner must accordingly a foil elements (flat material sheet) are performed, which at a smaller thickness of individual foil elements (flat material sheets) leads to higher costs.
Bei bestimmten sehr geringen Dicken der Folienelemente (Flachmaterialbögen) ist es möglich, diese an Stelle eines Werkzeugs mit dem Finger abzuschälen, so dass auch hierin ein Vorteil in Bezug auf das Handling der Folien zu sehen ist. Dies wird erreicht, indem vom Hersteller beim fertigen Produkt vorab auf der Seite der dünnen Folienelemente eine kleine Partie der Folie angeschält wird. Somit dient dies dem Anwender als eine Art„Fingerlift" für werkzeugloses Anschälen dieser Seite. Gleichzeitig kann auch die dünne von der dickeren Folienelemente unterschieden werden, da per Definition nur auf der dünnen Seite vorab angeschält wird. Die Unterscheidung wird zudem unterstützt, indem auf der Seite des Fingerlifts eine optische Kennung, beispielsweise eine dreizeilige Linie, angedruckt wird. With certain very small thicknesses of the film elements (flat material sheets), it is possible to peel them off in place of a tool with the finger, so that also here an advantage in terms of the handling of the films can be seen. This is achieved by the manufacturer of the finished product in advance on the side of the thin film elements a small batch of film is peeled. At the same time, the thin can be differentiated from the thicker foil elements, since by definition only the thin side is peeled in. The differentiation is also supported by using the Side of the finger lift an optical identifier, such as a three-line line is printed.
Besonders bevorzugt im Sinne der vorliegenden Erfindung handelt es sich bei den Folienelementen um metallische Folien, Polymerfolien, Faserverbundwerkstoffe, Gewebe und/oder Vliese aus Fasern, im Wesentlichen um Glas-, Kohlenstoff-, Keramik- oder Aramidfasern oder um eine Mischung verschiedener Materialen untereinander. Diese können beliebig untereinander kombiniert werden. Bevorzugt kann es sein, die Zwischenlagen mit wenigstens zwei Sorten von Folienelementen unterschiedlicher Dicke auszustatten. Besonders bevorzugt im Sinne der vorliegenden Erfindung verhält sich die Dicke einer ersten Sorte von Folienelemente zu der Dicke einer zweiten Sorte von Folienelemente im Verhältnis von 10 zu 2 bis 10 zu 7, insbesondere 10 zu 5, das heißt die einzelne Folienelemente ist halb so dick wie die anderen Folienelemente. Beispielsweise ist es möglich, die erste Sorte von Folienelemente dahingehend auszustatten, dass deren Dicke 0,05 mm beträgt, während die Dicke der zweiten Sorte von Folienelemente (Flachmaterialbögen) beispielsweise 0,025 mm (10 zu 5) beträgt. Damit ist es möglich, beim entsprechenden Einsatz der Zwischenlagen (Toleranzausgleich-Schichtfolien) zu gegebener Zeit einen Toleranzausgleich von entweder 0,05 mm oder 0,025 mm vorzunehmen. For the purposes of the present invention, the film elements are particularly preferably metallic foils, polymer foils, fiber composite materials, woven fabrics and / or nonwovens made of fibers, essentially glass, carbon, ceramic or aramid fibers or a mixture of different materials with one another. These can be combined with each other as desired. It may be preferable to equip the intermediate layers with at least two types of film elements of different thickness. Particularly preferred according to the present invention, the thickness of a first type of film elements to the thickness of a second type of film elements in the ratio of 10 to 2 to 10 to 7, in particular 10 to 5, that is, the individual film elements is half as thick as the other foil elements. For example, it is possible the first variety of sheet members to have a thickness of 0.05 mm, while the thickness of the second kind of sheet members (sheet sheets) is 0.025 mm (10 to 5), for example. This makes it possible, with the appropriate use of the intermediate layers (tolerance compensation layer films) to make a tolerance compensation of either 0.05 mm or 0.025 mm in due course.
Durch die Kombination von dünnen und dickeren Schichtdicken kann man besonders geschickt im Falle von dem Wunsch nach Verwendung von Compositen (Polymer- oder Faserverbundstoffe) auch sehr geringe Abstimmintervalle ermöglichen, die bei der Verwendung von Compositen den Nachteil der hohen Nachgiebigkeit aufweisen. In der erfindungsgemäßen Ausführung können nun übliche Dicken von Compositschichten mit sehr dünnen Schichten, gebildet zum Beispiel aus Metallfolien von kleiner 0,050 mm, kombiniert werden. Der Vorteil beruht auf dem Effekt, dass die Steifigkeit bei dünnen Compositschichten mit abnehmender Dicke immer mehr von dem relativ nachgiebigen Harz beeinflusst wird. The combination of thin and thicker layer thicknesses makes it possible, especially in the case of the desire to use composites (polymer or fiber composites), to allow even very short tuning intervals, which have the disadvantage of high flexibility when composites are used. In the embodiment according to the invention, it is now possible to combine conventional thicknesses of composite layers with very thin layers, formed, for example, of metal foils of less than 0.050 mm. The advantage stems from the effect that stiffness in thin composite layers is increasingly affected by the relative compliant resin as the thickness decreases.
Wesentlich im Sinne der vorliegenden Erfindung kann es sein, dass die Fläche zwischen zwei Folienelementen nicht wie im Stand der Technik bisher üblich, vollständig mit Klebstoff belegt ist. Wenn im vorliegenden Fall definiert wird, dass lediglich 10 bis 50% der Fläche einer Folienelementes mit dem Klebstoff bedeckt ist, so bedeutet dies, dass die übrigen Flächenbereiche der Folienelemente frei und ohne verbindenden Kontakt aufeinander liegen. Die freie Beweglichkeit in diesen Flächen abschnitten ermöglicht es, in besonders einfacher Weise einzelne Folienelemente ohne Einsatz von Werkzeug allein mit dem Finger voneinander zu trennen. In einem gattungsfremden Stand der Technik ist dieses Grundprinzip bei der Herstellung von Haftnotizen (Post-It®) verwirklicht. Erfindungsgemäß ist es jedoch nicht erforderlich, wenngleich möglich auch die Stirnseiten der Folienelemente miteinander zu verkleben. For the purposes of the present invention, it may be essential that the surface between two film elements is not completely covered with adhesive, as has hitherto been customary in the prior art. If it is defined in the present case that only 10 to 50% of the area of a film element is covered with the adhesive, this means that the remaining areas of the film elements lie freely and without connecting contact. The free mobility sections in these areas makes it possible in a particularly simple manner individual film elements without the use of tools alone with the To separate fingers. In a non-generic state of the art, this basic principle in the production of sticky notes (Post-It®) is realized. According to the invention, however, it is not necessary, if possible, to bond the end faces of the film elements to one another.
Anstelle der Auftragung des Klebstoffes zwischen den Folienelementen in einem einzelnen Punkt, der sich naturgemäß bei dem Verpressen der Folienelemente entsprechend vergrößert, besteht selbstverständlich auch die Möglichkeit, den Klebstoff in einer Vielzahl von kleinen Punkten anzubringen, sodass eine rasterförmige Anordnung dieser entsteht. Diese rasterförmige Anordnung kann sich über die gesamte Fläche einzelner Folienelemente erstrecken, wobei jedoch hier die Grenzwerte der Flächenbedeckung, wie oben dargelegt, eingehalten werden müssen. Alternativ ist es jedoch ebenso möglich, die rasterförmige Anordnung des Klebstoffs auf bestimmte vordefinierte Flächenabschnitte zu begrenzen. Instead of applying the adhesive between the film elements in a single point, which naturally increases correspondingly in the pressing of the film elements, it is of course also possible to attach the adhesive in a plurality of small dots, so that a grid-like arrangement of these arises. This grid-shaped arrangement may extend over the entire surface of individual film elements, but here the limits of the area coverage, as stated above, must be complied with. Alternatively, however, it is also possible to limit the grid-shaped arrangement of the adhesive to certain predefined area sections.
Ein weiterer Vorteil der erfindungsgemäßen Ausführungsform besteht darin, dass man abgeschälte Zwischenlagen wiederverwenden kann. Gerade bei metallischen laminierten Zwischenlagen ist das nicht zu vernachlässigen, da somit kein„zu viel" an Abschälen stattfinden kann, da eine abgezogene Lage ihre Form behält und sich nicht zusammenrollt und somit Abfall würde. Damit reduziert sich also auf alle Fälle auch der Ausschuss, der durch normale Handhabung manchmal passieren kann. Das spricht dann sehr für die „ein Bauteil"- Lösung, da man keinen Ausschuss einplanen muss. Ein Verfahren zur Herstellung einer Zwischenlage mit einer durch Schichtspaltung anpassbaren Gesamtdicke, besteht darin, mit einem Schichtungsvorgang, bei dem eine abwechselnde Schichtung von Folienelementen und gegebenenfalls von Klebstoff gebildet wird, wobei man Folienelemente einer ersten und zweiten Dicke auswählt und wenigstens ein erstes Folienelement der ersten Dicke auf wenigstens einer Fläche teilweise oder vollständig mit einem Klebstoff versieht, gegebenenfalls verpresst, ein zweites Folienelement auf die Klebstofffläche auflegt, gegebenenfalls verpresst, die dann freiliegende Fläche des zweiten Folienelementes analog dem ersten Folienelement mit einem Klebstoff versieht und diese Verfahrensschritte bis zur Gesamtdicke der Zwischenlage wiederholt, wobei innerhalb der Wiederholungsschritte anstelle der Folienelemente der ersten Dicke, Folienelemente (Folien) der zweiten Dicke eingesetzt werden (Jokerfolie). Another advantage of the embodiment of the invention is that you can reuse peeled liners. This is not to be neglected, especially with metallic laminated liners, since no "too much" peeling can take place since a stripped layer retains its shape and does not curl up and thus waste, which reduces the rejects in any case. which can sometimes happen due to normal handling, which is very much in favor of the "one component" solution because you do not have to plan any waste. A method of making an intermediate layer having a total interfacial thickness which can be adjusted by delamination is to form a lamination process in which an alternating lamination of film elements and optionally adhesive is formed, selecting one of first and second thickness film elements and at least one first film element of the first one Provides thickness on at least one surface partially or completely with an adhesive, optionally pressed, a second film element hangs on the adhesive surface, optionally pressed, then the exposed surface of the second film element similar to the first film element with an adhesive and these process steps to the total thickness of the intermediate layer repeated, wherein within the repetition steps, instead of the foil elements of the first thickness, foil elements (foils) of the second thickness are used (Joker foil).
In dem Fall, dass anstelle einer Folie ein Gewebe eingesetzt wird, umfasst das Verfahren auch einen Schichtungsvorgang, bei dem ein Gewebe als Folienelement ausgewählt und auf seiner gesamten Fläche und seiner Dicke mit einem Klebstoff getränkt wird. In the case where a fabric is used instead of a film, the method also includes a laminating process in which a fabric is selected as a film element and impregnated with an adhesive over its entire area and its thickness.
Ein weiteres Verfahren zur Herstellung einer Zwischenlage mit einer durch Schichttrennung anpassbaren Gesamtdicke besteht darin, gegebenenfalls nach Aufrauen der Stirnseiten einer Schichtung von Folienelementen, diese mit einem Klebstoff analog einem Buchrücken zu versehen. In einem zweiten Schritt wird dann der Klebstoff ausgehärtet. Alternativ ist es auch möglich, eine lose oder komprimierte Schichtung von Folienelementen in ein Bad mit dem Klebstoff einzutauchen oder die Stirnseiten der Folienelemente mit dem Klebstoff zu besprühen. Damit werden die Zwischenlagen mit unterschiedlichen, aber auch mit gleichen Dicken der Folienelemente, nur in Teilbereichen der Folienelemente mit Klebestoff versehen, wobei dies nur am Umfang, also den Stirnflächen der Folienelemente, erfolgt. Another method for producing an intermediate layer with a total thickness which can be adjusted by means of layer separation consists, if appropriate after roughening the end faces of a layer of film elements, of providing them with an adhesive analogously to a spine of the book. In a second step, the adhesive is then cured. Alternatively, it is also possible to immerse a loose or compressed layer of film elements in a bath with the adhesive or to spray the end faces of the film elements with the adhesive. Thus, the intermediate layers are provided with different, but also with the same thicknesses of the film elements, only in partial areas of the film elements with adhesive, which takes place only at the periphery, ie the end faces of the film elements.
Sämtlichen Ausführungen der vorliegenden Erfindung ist gemein, dass diese auch die Variante umfassen können, dass die Zwischenlage nur ein Folienelement (Folie) geringerer Dicke auf einer Oberfläche der Zwischenlage aufweisen kann (Jokerfolie). All embodiments of the present invention have in common that they may also include the variant in that the intermediate layer can only have a foil element (foil) of lesser thickness on a surface of the intermediate layer (joker foil).
Gemäß einer weiteren Ausgestaltung betrifft die Erfindung die abziehbaren Einstellelemente für mechanische Konstruktionen nicht paralleler Spalte. According to a further embodiment, the invention relates to the peelable adjustment elements for mechanical structures of non-parallel column.
Besonders bevorzugt werden daher die einzelnen Folienelemente (Lagen) in der Form des Endprodukts ausgeschnitten oder ausgestanzt, um diese exakt übereinander zu stapeln. Anschließend werden die Lagen fixiert um dann die vorher definierte(n) Stirnfläche(n)/umlaufende(n) Kante(n) mit Klebstoff zu versehen. Der Klebstoff sollte elastisch genug sein, um mechanische Festigkeit bei geringer Benutzungsfläche zu bieten und den Erschütterungen durch Handhabung und Transport zu widerstehen. With particular preference, the individual film elements (layers) are therefore cut out or punched out in the form of the end product in order to stack them exactly one above the other. Subsequently, the layers are fixed in order then to provide the previously defined end face (s) / circumferential edge (s) with adhesive. The adhesive should be elastic enough to provide mechanical strength with little footprint and to withstand handling and transportation shocks.
