Description

Die Erfindung betrifft eine Vorrichtung zum Festhalten eines druckempfindlichen weissgetrockneten Keramikgegenstandes an einer Auflagefläche eines Auflageteiles.The invention relates to a device for holding a pressure-sensitive, white-dried ceramic object on a support surface of a support part.

Bei der Bearbeitung druckempfindlicher weissgetrockneter Keramikgegenstände wie Waschbecken, Toilettenschüsseln o.dgl. ist das Festhalten der Keramikgegenstände während der Durchführung verschiedener Arbeitsgänge an den Keramikgegenständen deshalb problematisch, weil die Keramikgegenstände unterschiedliche Formen und Gestalten aufweisen können und weil der spezifische Flächendruck auf die weissgetrockneten Keramikgegenstände während des Festhaltens derselben infolge ihrer Druckempfindlichkeit nur relativ gering sein darf.When processing pressure-sensitive white-dried ceramic objects such as sinks, toilet bowls or the like. the holding of the ceramic objects during the execution of various operations on the ceramic objects is problematic because the ceramic objects can have different shapes and shapes and because the specific surface pressure on the white-dried ceramic objects while holding them may only be relatively low due to their pressure sensitivity.

Die US-PS 4 813 657 offenbart eine Vorrichtung zum Festhalten eines Werkstückes, bei dem es sich beispielsweise um eine Glasplatte handeln kann. Diese bekannte Vorrichtung weist einen kanalförmigen Rahmen auf, der sich entlang des Umfangsrandes des Werkstückes erstrecken kann. Der kanalförmige Rahmen ist mit einem unteren und einem oberen Halteelement ausgebildet, wobei das obere Halteelement mit einem aufblasbaren bzw. kollabierenden Schlauchelement versehen ist. Mit diesem Schlauchelement ist der Abstand zum unteren Halteelement und somit die Spannweite zwischen dem unteren und dem oberen Halteelement wunschgemäß einstellbar. Durch das Schlauchelement ergibt sich am festzuhaltenden Werkstück jedoch nur eine relativ kleine Anlagefläche und folglich eine relativ große Flächenpressung. Das mag beim Festhalten von Glasplatten od. dgl. unkritisch sein; zum Festhalten eines druckempfindlichen weissgetrockneten Keramikgegenstandes ist eine solche Vorrichtung nicht vorgesehen bzw. geeignet.US Pat. No. 4,813,657 discloses a device for holding a workpiece, which may be a glass plate, for example. These known device has a channel-shaped frame which can extend along the peripheral edge of the workpiece. The channel-shaped frame is formed with a lower and an upper holding element, the upper holding element being provided with an inflatable or collapsing hose element. With this hose element, the distance to the lower holding element and thus the span between the lower and the upper holding element can be set as desired. The hose element, however, results in only a relatively small contact surface on the workpiece to be held and consequently a relatively large surface pressure. This may not be critical when holding glass plates or the like; Such a device is not provided or suitable for holding a pressure-sensitive white-dried ceramic object.

Aus der GB-PS 1 418 483 ist eine Vorrichtung bekannt, die zum Verbinden zweier Bauteile durch Verkleben vorgesehen ist. Diese bekannte Vorrichtung weist ein Grundteil mit einer Saugöffnung sowie eine das Grundteil überspannende Membrane auf. Die Membrane ist auf dem Grundteil mittels eines umlaufenden Dichtungsorganes festlegbar. Sie wird am Grundteil festgelegt, nachdem die miteinander zu verklebenden Bauteile passend am Grundteil angeordnet worden sind. Um die zu verbindenden Bauteile während des Klebevorganges zuverlässig aneinander festzulegen und in der passend positionierten Stellung festzuhalten, ist zwischen der Membrane und den zu verklebenden Bauteilen wenigstens ein Abstandselement vorgesehen, das genau an der Verbindungsstelle wirksam ist. Zum Festhalten eines druckempfindlichen weissgetrockneten Keramikgegenstandes ist auch diese bekannte Vorrichtung nicht vorgesehen oder geeignet.From GB-PS 1 418 483 a device is known which is provided for connecting two components by gluing. This known device has a base part with a suction opening and a membrane spanning the base part. The membrane can be fixed on the base part by means of a circumferential sealing element. It is fixed on the base part after the components to be glued together have been arranged on the base part. In order to reliably fix the components to be connected to one another during the gluing process and to hold them in the appropriately positioned position, at least one spacing element is provided between the membrane and the components to be glued, which is effective at the connection point. This known device is also not provided or suitable for holding a pressure-sensitive white-dried ceramic object.

Die US-PS 2 417 539 beschreibt eine Bohrlehre, die für die Tragflügel von Flugzeugen vorgesehen ist. Diese Bohrlehre weist ein flexibles flächiges Spannelement aus mehreren Gummischichten auf. Das flexible Spannelement wird über den mit Bohrlöchern zu versehenden Tragflügel gespannt.US Pat. No. 2,417,539 describes a drilling jig which is intended for the wings of aircraft. This drilling jig has a flexible flat clamping element made of several rubber layers. The flexible tensioning element is stretched over the wing to be drilled.

Eine Vorrichtung, die insbesondere zum Ausbessern beschädigter Flächenelemente vorgesehen ist, ist aus der US-PS 3 661 683 bekannt. Diese Vorrichtung weist ein aufblasbares Volumen auf, das mittels Stützorganen am schadhaften Flächenelement festlegbar ist. Bei den Stützorganen handelt es sich vorzugsweise um Saugknöpfe. Das aufblasbare Volumen wirkt dort auf das beschädigte Flächenelement bzw. auf ein das beschädigte Flächenelement ausbesserndes bzw. wieder herstellendes Flächenteil als Preßstempel ein, so daß es möglich ist, das besagte Flächenteil z.B. am zu reparierenden Flächenelement festzukleben.A device which is provided in particular for repairing damaged surface elements is known from US Pat. No. 3,661,683. This device has an inflatable volume which can be fixed on the defective surface element by means of support members. The support members are preferably suction buttons. The inflatable volume acts there on the damaged surface element or on a surface part that repairs or restores the damaged surface element as a press ram, so that it is possible to e.g. to be glued to the surface element to be repaired.

Aus der DE-PS 30 34 101 ist eine Vorrichtung zum Halten, Ausrichten und Befestigen eines mit Klebstoff versehenen Montageteiles auf einer Montagefläche bekannt, wobei ein Tragkörper für das Montageteil zwecks Bewegung zwischen einer ersten Lage, in der das Montageteil von der Montagefläche beabstandet ist, und einer zweiten Lage vorgesehen ist, in der das Montageteil in Auflageeingriff mit der Montagefläche ist. Dort ist ein nachgiebiger Montageträger vorgesehen, der von dem Tragkörper gehalten ist. Ein Verbinder ist zum zeitweiligen Befestigen des nachgiebigen Montageträgers an der Montagefläche neben dem Montageteil vorgesehen. Der Tragkörper ist zwischen der ersten und der zweiten Lage bewegbar, während der Verbinder an der Oberfläche festgelegt ist. Der nachgiebige Montageträger ist zwischen dem Tragkörper und der Montagefläche vorgesehen. Der Montageträger wird bei Bewegung des Tragkörpers in die zweite Lage unter Druck gesetzt, um zwischen dem Tragkörper und der Montagefläche eine Reaktion hervorzurufen, den Tragkörper zum Montageteil hin zu drücken und somit das Montageteil in Richtung zur Montagefläche zu pressen. Der Verbinder umfaßt dort vorzugsweise einen Klebstoffauftrag.From DE-PS 30 34 101 a device for holding, aligning and fastening a mounting part provided with adhesive on a mounting surface is known, a supporting body for the mounting part for the purpose of movement between a first position in which the mounting part is spaced from the mounting surface, and a second position is provided, in which the mounting part is in engagement engagement with the mounting surface. There is a flexible mounting bracket is provided, which is held by the support body. A connector is provided for temporarily securing the resilient mounting bracket to the mounting surface adjacent to the mounting member. The support body is movable between the first and the second layer, while the connector is fixed on the surface. The compliant Mounting bracket is provided between the support body and the mounting surface. When the support body is moved into the second position, the mounting bracket is pressurized in order to cause a reaction between the support body and the mounting surface, to press the mounting body towards the mounting part and thus to press the mounting part towards the mounting surface. The connector there preferably comprises an adhesive application.

Die DD 251 102 beschreibt eine Vorrichtung zum Fixieren von Werkstücken für die mechanische Feinbearbeitung bzw. für Meßvorgänge, wobei das Werkstück auf einer Dreipunktauflage aufliegt. Dort soll eine Fixierung des Werkstückes durch Formschluß erreicht werden. Das wird dadurch erzielt, daß das Werkstück durch einen Spanngummi auf der Aufspannfläche unter gleichzeitiger Entlastung durch eine Stützmembran gehalten wird. Diese bekannte Vorrichtung wird beispielsweise bei der Bearbeitung von Siliciumplatten angewandt.DD 251 102 describes a device for fixing workpieces for mechanical finishing or for measuring processes, the workpiece resting on a three-point support. There, the workpiece is to be fixed by positive locking. This is achieved in that the workpiece is held by a clamping rubber on the clamping surface while relieved by a supporting membrane. This known device is used for example in the processing of silicon plates.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die einfach ausgebildet ist, und mit welcher weissgetrocknete druckempfindliche Keramikgegenstände zuverlässig und sicher an einem Auflageteil festgehalten werden können, ohne dass auf die festzuhaltenden Keramikgegenstände ein zu hoher spezifischer Flächendruck wirksam wird.The invention has for its object to provide a device of the type mentioned, which is simple, and with which white-dried pressure-sensitive ceramic objects can be reliably and securely held on a support part without an excessive surface pressure acting on the ceramic objects to be held .

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des kennzeichnenden Teiles des Anspruchs 1 gelöst. Weiterbildungen der erfindungsgemäßen Vorrichtung sind in den Unteransprüchen gekennzeichnet.This object is achieved according to the invention by the features of the characterizing part of claim 1. Further developments of the device according to the invention are characterized in the subclaims.

Die Ausbildung des flächigen Spannelementes als Membrane weist den Vorteil auf, dass es sich praktisch allen beliebigen Formen von druckempfindlichen weissgetrockneten Keramikgegenständen derart anpasst, dass das flächige Spannelement an dem am Auflageteil der Vorrichtung festzuhaltenden Keramikgegenstand flächig anliegt. Dadurch ist während der Halterung des Gegenstandes der auf ihn wirksam werdende spezifische Flächendruck relativ gering.The design of the flat clamping element as a membrane has the advantage that it adapts to practically any shape of pressure-sensitive white-dried ceramic objects in such a way that the flat clamping element lies flat against the ceramic object to be held on the support part of the device. As a result, the specific surface pressure acting on it is relatively low while the object is being held.

Das Spannelement ist aus einem elastischen und biegeschlaffen Material ausgebildet. Je nach der Empfindlichkeit des Gegenstandes, insbes. des druckempfindlichen weissgetrockneten Keramikgegenstandes, und je nach den Arbeitsgängen, welchen der Gegenstand ausgesetzt wird, ist es selbstverständlich auch möglich, den Gegenstand mit mehreren Spannelementen aus unterschiedlichen Richtungen festzuhalten. Hierbei können die erforderlichen Spannkräfte der einzelnen Spannelemente individuell für jedes zu spannende Spannelement ermittelt werden.The tensioning element is made of an elastic and pliable material. Depending on the sensitivity of the object, in particular the pressure-sensitive white-dried ceramic object, and depending on the operations to which the object is exposed, it is of course also possible to hold the object with several clamping elements from different directions. The required clamping forces of the individual clamping elements can be determined individually for each clamping element to be clamped.

Die Führungseinrichtung kann zur Auflagefläche des Auflageteiles mindestens annähernd senkrecht orientiert sein und das zur Auflagefläche des Auflageteiles mindestens annähernd parallel orientierte flächige flexible Spannelement weist vorzugsweise eine Umfangskontur auf, die grösser ist als die Umfangskontur des auf dem Auflagetisch zu haltenden Gegenstandes in Projektion auf die Auflagefläche des Auflageteiles. Durch eine solche Ausbildung der Vorrichtung ist es möglich, dass das mindestens eine Spannelement den am Auflageteil festzuhaltenden Gegenstand überspannt, wobei sich durch dieses Überspannen gleichzeitig auch eine seitliche Festhaltekraft ergibt, durch welche eine seitliche Bewegung des Gegenstandes relativ zum Auflageteil, d.h. ein Verrutschen des Gegenstandes entlang der Auflagefläche des Auflageteiles verhindert wird. Es ergibt sich folglich eine sichere und zuverlässige Festlegung des Gegenstandes am Auflageteil, so dass es auch möglich ist, die Vorrichtung derart auszubilden, dass das Auflageteil mit dem an ihm festgehaltenen Gegenstand in verschiedene Winkelstellungen verstellt wird, um am Gegenstand gut zugännglich diverse Arbeiten durchführen zu können. Zu diesem Zweck können das Auflageteil und die mindestens eine Führungseinrichtung für das entsprechende Spannelement in einem Gehäuse vorgesehen sein, das um eine zur Auflagefläche des Auflageteiles mindestens annähernd parallele und zu mindestens einer Führungseinrichtung annähernd senkrechte Achse schwenkbar bzw. drehbeweglich gelagert ist. Hierbei kann das Gehäuse als Trommel ausgebildet sein, an welcher zu ihrer beweglichen Lagerung Führungswalzen anliegen. Damit bei einer solchen Ausbildung der Vorrichtung weder durch das Auflageteil noch durch die mindestens eine Führungseinrichtung für das zugehörige Spannelement die Schwenk- bzw. Drehbeweglichkeit des trommelförmigen Gehäuses beeinträchtigt wird, ist es zweckmässig, wenn die Führungswalzen an der Aussenseite der Trommel anliegen.The guide device can be oriented at least approximately vertically to the support surface of the support part and the flat flexible clamping element oriented at least approximately parallel to the support surface of the support part preferably has a circumferential contour that is larger than the circumferential contour of the object to be held on the support table in projection onto the support surface Support part. Such a design of the device makes it possible for the at least one tensioning element to be attached to the support part spanned object to be held, this spanning also results in a lateral holding force, by means of which lateral movement of the object relative to the support part, ie slipping of the object along the support surface of the support part, is prevented. This results in a secure and reliable fixation of the object on the support part, so that it is also possible to design the device in such a way that the support part with the object held on it is adjusted into different angular positions in order to carry out various work on the object in an easily accessible manner can. For this purpose, the support part and the at least one guide device for the corresponding clamping element can be provided in a housing which is pivotably or rotatably mounted about an axis which is at least approximately parallel to the support surface of the support part and approximately perpendicular to at least one guide device. Here, the housing can be designed as a drum, on which guide rollers rest for their movable mounting. So that the pivoting or rotating mobility of the drum-shaped housing is not impaired by such a design of the device, neither by the support part nor by the at least one guide device for the associated tensioning element, it is expedient if the guide rollers bear against the outside of the drum.

Fig. 1 zeigt in einer Vorderansicht schematisch eine Vorrichtung 10 mit einem Auflageteil 12, das mit einer Auflagefläche 14 für einen Gegenstand 16 ausgebildet ist. Bei dem Auflageteil 12 kann es sich bspw. um einen Auflagetisch bzw. um einen Boden handeln. Bei dem Gegenstand 16 handelt es sich vorzugsweise um einen druckempfindlichen weissgetrockneten Keramikgegenstand wie einem Waschbecken, einer Toilettenschüssel, einem Bidetbecken o.dgl.1 shows a front view schematically of a device 10 with a support part 12, which is designed with a support surface 14 for an object 16. The support part 12 can, for example, be a support table or a floor. The object 16 is preferably a pressure-sensitive white-dried ceramic object such as a wash basin, a toilet bowl, a bidet basin or the like.

Die Vorrichtung weist ausserdem mindestens ein flächiges flexibles Spannelement 18 auf, bei dem es sich z.B. um eine Membrane aus einem elastisch nachgiebigen Material handelt. Das Spannelement 18 ist entlang einer zugehörigen Führungseinrichtung 20 in bezug auf das Auflageteil 12 bzw. die Auflagefläche 14 des Auflageteils 12 beweglich geführt, was durch die Zeile 22 angedeutet ist. Die Führungseinrichtung 20 ist nur durch dünne strichpunktierte Linien verdeutlicht.The device also has at least one flat flexible clamping element 18, which is e.g. is a membrane made of a resilient material. The clamping element 18 is movably guided along an associated guide device 20 with respect to the support part 12 or the support surface 14 of the support part 12, which is indicated by the line 22. The guide device 20 is only illustrated by thin dash-dotted lines.

Das Auflageteil 12 und die mindestens eine Führungseinrichtung 20 für das zugehörige Spannelement 18 sind in einem Gehäuse 24 angeordnet, das als zylindrische Trommel ausgebildet ist. An der Aussenseite des trommelförmigen Gehäuses 24 liegen Führungswalzen 26 an, von welchen mindestens eine mit einer Antriebseinrichtung verbunden ist, um das trommelförmige Gehäuse 24 um seine zentrale Achse 28 verschwenken bzw. drehen zu können, was durch den Doppelpfeil 30 angedeutet ist.The support part 12 and the at least one guide device 20 for the associated clamping element 18 are arranged in a housing 24 which is designed as a cylindrical drum. On the outside of the drum-shaped housing 24 there are guide rollers 26, at least one of which is connected to a drive device in order to be able to pivot or rotate the drum-shaped housing 24 about its central axis 28, which is indicated by the double arrow 30.

In Fig. 2, in welcher gleiche Einzelheiten wie in Fig. 1 mit denselben Bezugsziffern wie in Fig. 1 bezeichnet sind, ist das Auflageteil 12, auf dessen Auflagefläche 14 der Gegenstand 16 angeordnet ist, schraffiert gezeichnet.In Fig. 2, in which the same details as in Fig. 1 are denoted by the same reference numerals as in Fig. 1, the support part 12, on the support surface 14 of which the object 16 is arranged, is hatched.

Aus Fig. 3 ist ersichtlich, dass das Spannelement 18, das in seinem mittleren Teil ausgeschnitten gezeichnet ist, um den Gegenstand 16 zu verdeutlichen, rechteckig ausgebildet und mit seinen Eckenabschnitten 32 entlang der zugehörigen Führungseinrichtung 20 geführt ist. Aus dieser Figur ist auch ersichtlich, dass das Spannelement 18 eine Flächenausdehnung aufweist, die allseitig grösser ist als die Grundfläche des Gegenstandes 16 in senkrechter Projektion auf die Auflagefläche 14 des Auflageteiles 12 der Vorrichtung 10. Dadurch ist es möglich, den Gegenstand 16 allseitig in bezug auf die Auflagefläche 14 des Auflageteiles 12 sicher festzuhalten, wenn das Spannelement 18 über den Gegenstand 16 gestülpt bzw. gespannt wird, was in den Figuren 4, 5 und 6 deutlich ersichtlich ist. Diese Figuren zeigen das flächige Spannelement 18 in seiner aktiven Betriebsstellung, in welcher das Spannelement 18 mit einer bestimmten Spannkraft F und dementsprechend der Gegenstand 16 gegen die Auflagefläche 14 des Auflageteiles 12 gezwängt ist, so dass der Gegenstand 16 sicher und zuverlässig, d.h. gegen seitliche Verschiebungen gesichert, an der Auflagefläche 14 des Auflageteiles 12 festgehalten wird. In diesem Zustand ist es auch möglich, die Vorrichtung 10 um ihre zentrale Achse 28 zu verschwenken bzw. zu verdrehen, was durch den Doppelpfeil 30 in Fig. 6 angedeutet ist, um an dem Gegenstand 16 entsprechende Arbeiten auszuführen. Mit Hilfe des flexiblen Spannelementes 18 ergibt sich an jedem beliebigen Gegenstand 16 eine mehr oder weniger grossflächige Anlage und somit ein vergleichsweise kleiner spezifischer Flächendruck auf den druckempfindlichen Gegenstand 16. Es ergeben sich folglich die Vorteile, dass eine Beschädigung des Gegenstandes 16 während seiner Halterung durch zu grosse Druckeinwirkungen verhindert wird, wobei gleichzeitig in jeder beliebigen Lage des Gegenstandes 16, die horizontal, vertikal oder beliebig schräg sein kann, eine sichere und zuverlässige Halterung des Gegenstandes 16 zwischen dem Spannelement 18 und dem Auflageteil 12 der Vorrichtung 10 gegeben ist. Fig. 7 zeigt wiederum die Ausbildung des flächigen flexiblen Spannelementes 18 mit rechteckiger Grundflächengestalt, wobei das rechteckige Spannelement mit seinen Eckenabschnitten 32 entlang der Führungseinrichtung 20, welche vier entsprechende Führungssäulen aufweist, in bezug auf das Auflageteil 12 zwischen einer in den Figuren 1 bis 3 gezeichneten Ruheposition und einer in den Figuren 4 bis 7 gezeichneten aktiven Betriebs- bzw. Spannposition verstellbar ist.From Fig. 3 it can be seen that the clamping element 18, which is drawn cut out in its central part to illustrate the object 16, is rectangular and is guided with its corner sections 32 along the associated guide device 20. From this figure it can also be seen that the clamping element 18 has a surface area which is larger on all sides than the base surface of the object 16 in a vertical projection onto the bearing surface 14 of the bearing part 12 of the device 10. This makes it possible to relate the object 16 on all sides to securely hold onto the support surface 14 of the support part 12 when the clamping element 18 is slipped or stretched over the object 16, which is clearly visible in FIGS. 4, 5 and 6. These figures show the flat clamping element 18 in its active operating position, in which the clamping element 18 with a certain clamping force F and accordingly the object 16 is forced against the support surface 14 of the support part 12, so that the object 16 is safe and reliable, ie against lateral displacements secured, is held on the support surface 14 of the support member 12. In this state, it is also possible to pivot or twist the device 10 about its central axis 28, which is indicated by the double arrow 30 in FIG. 6, in order to carry out corresponding work on the object 16. With the aid of the flexible clamping element 18, a more or less large-area system is obtained on any object 16 and thus a comparatively small specific surface pressure on the pressure-sensitive object 16. There are consequently the advantages that damage to the object 16 during its holding by excessive pressure is prevented, while at the same time in any position of the object 16, the horizontal, vertical or can be inclined as desired, a secure and reliable holding of the object 16 between the clamping element 18 and the support part 12 of the device 10 is given. Fig. 7 shows again the formation of the flat flexible clamping element 18 with a rectangular base shape, the rectangular clamping element with its corner sections 32 along the guide device 20, which has four corresponding guide columns, with respect to the support part 12 between one shown in Figures 1 to 3 Rest position and an active operating or clamping position shown in Figures 4 to 7 is adjustable.

In den Figuren 4 bis 7 sind gleiche Einzelheiten wie in den Figuren 1 bis 3 mit denselben Bezugsziffern wie dort bezeichnet.In FIGS. 4 to 7, the same details as in FIGS. 1 to 3 are denoted by the same reference numerals as there.
