Description
Werkzeug Tool
Die Erfindung bezieht sich auf ein Werkzeug zur Schaffung einer homogenen Oberfläche im Sichtbereich einer auf einer Scheibe extrudierten Polyurethanraupe (PUR-Raupe).The invention relates to a tool for creating a homogeneous surface in the visible area of a polyurethane bead (PUR bead) extruded on a disk.
Es ist allgemein bekannt, flüssiges bzw. viskoses PUR-Material mittels einer der Form eines Dichtungsstreifens entsprechenden Düse entlang eines Scheibenrandes zu extrudieren. An einer Übergangsstelle zwischen Anfang und Ende der PRU-Raupe ergeben sich jedoch Schwierigkeiten, eine homogene Sichtfläche zu erzielen. It is generally known to extrude liquid or viscous PUR material along the edge of a pane using a nozzle that corresponds to the shape of a sealing strip. However, at a transition point between the beginning and end of the PRU bead, difficulties arise in achieving a homogeneous visible surface.
Der Erfindung liegt die Aufgabe zugrunde, eine einfach aufgebaute Vorrichtung anzugeben, mit der auf sichere Weise im Sichtbereich der Übergangsstelle einer extrudierten PUR-Raupe eine gute Oberflächenqualität erzielt wird.The invention is based on the object of specifying a simply constructed device with which a good surface quality can be achieved in a reliable manner in the visible area of the transition point of an extruded PUR bead.
Diese Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterising part of claim 1.
&Ggr; Eine PUR-Folie von bestimmter Stärke wird zwischen Werkzeug und PUR-Raupe an der Übergangsstelle angeordnet. Die Folie wird mit der PUR-Raupe verbunden, wodurch eine gute Sichtflächenqualität erzielt wird. &Ggr; A PUR film of a certain thickness is placed between the tool and the PUR bead at the transition point. The film is bonded to the PUR bead, which results in a good visible surface quality.
Die Erfindung wird nachfolgend anhand der Zeichnung näher erläutert.The invention is explained in more detail below with reference to the drawing.
Die Figur zeigt eine Schnittdarstellung des erfindungsgemäßen Werkzeuges.The figure shows a sectional view of the tool according to the invention.
Das Werkzeug 1 weist einen ersten Bereich la zur Aufnahme derThe tool 1 has a first area la for receiving the
Scheibe 2 sowie einen zweiten Bereich Ib zur Aufnahme einer Sichtfläche 3a einer PUR-Raupe 3 auf. Die Form des Bereiches Ib des Werkzeuges 1 entspricht im wesentlichen der Form des Teiles der PUR-Raupe 3 an der Sichtfläche 3a.Disc 2 and a second area 1b for receiving a visible surface 3a of a PUR bead 3. The shape of the area 1b of the tool 1 essentially corresponds to the shape of the part of the PUR bead 3 on the visible surface 3a.
Zwischen der Sichtfläche 3a und dem Werkzeug 1 ist eine PUR-Folie 4 angeordnet, die sich mindestens über die Sichtfläche 3a erstreckt. Die Folie 4 wird mittels Vakuum, mit dem sich in Längs- und Querrichtung des Werkzeuges 1 erstreckende Öffnungen 5 beaufschlagt sind, an das Werkzeug 1 angesaugt. Die jeweilig gleichförmigen, sich in Längsrichtung erstreckenden Öffnungen 5 sind über Anschlußbohrungen 6 miteinander verbunden und sind mit einer nicht gezeigten Druckminderungseinrichtung gekoppelt.A PUR film 4 is arranged between the visible surface 3a and the tool 1, which extends at least over the visible surface 3a. The film 4 is sucked onto the tool 1 by means of a vacuum, which is applied to openings 5 extending in the longitudinal and transverse directions of the tool 1. The respective uniform openings 5 extending in the longitudinal direction are connected to one another via connection holes 6 and are coupled to a pressure reduction device (not shown).
Der Aufnahmebereich la des Werkzeuges 1 für die Scheibe 2 ist vorzugsweise mit einem Einsatz 7 versehen, um bei sich ändernden Toleranzen ein schnelles Anpassen zu ermöglichen und die Glasflächen vor mechanischen Einflüssen zu schützen. Der Einsatz 7 besteht aus Polyamid oder einem anderen Kunststoff mit ähnlichen Eigenschaften.The receiving area la of the tool 1 for the pane 2 is preferably provided with an insert 7 in order to enable rapid adjustment in the event of changing tolerances and to protect the glass surfaces from mechanical influences. The insert 7 is made of polyamide or another plastic with similar properties.
Zur Bearbeitung wird das Werkzeug 1 mittig zwischen beiden Enden der PUR-Raupe 3 positioniert. Der der Sichtfläche 3a abgewandte Bereich wird mit Hilfe eines Spatels angeglichen.For processing, the tool 1 is positioned centrally between both ends of the PUR bead 3. The area facing away from the visible surface 3a is aligned using a spatula.
Nach Beendigung dieses Formvorganges wird die Vakuumbeaufschlagung unterbrochen und die Anschlußbohrungen 6 werden mit Druckluft versehen. Die Reihenfolge der Druckluftbeaufschlagung an den Anschlußbohrungen 6 geschieht wahlweise, um ein optimales Anliegen der PUR-Folie 4 an die PUR-Raupe 3 zu gewährleisten.After this forming process has been completed, the vacuum is interrupted and the connection holes 6 are supplied with compressed air. The order in which compressed air is applied to the connection holes 6 is optional in order to ensure that the PUR film 4 fits perfectly against the PUR bead 3.
Der beschriebene Ablauf des Spateins und Anblasens kann auch in umgekehrter Reihenfolge erfolgen. Anschließend wird das Werkzeug von der Glaskante bzw. der PUR-Raupe entfernt.The described process of spatula insertion and blowing can also be carried out in reverse order. The tool is then removed from the glass edge or the PUR bead.
Das Werkzeug kann auch mit mechanischen SteuereinrichtungenThe tool can also be equipped with mechanical control devices
versehen werden. So ist eine Automatisierung des gesamten Vorganges mit Hilfe von Sensoreinrichtungen möglich.This makes it possible to automate the entire process using sensor devices.
Die Folie 4 kann konfektioniert oder von Rolle zugeführt werden.The film 4 can be cut to size or fed from a roll.
Eine Automatisierung des Angleichens des der Sichtfläche 3a abgewandten Bereiches kann durch geeignete Vorrichtungen erzielt werden.Automation of the adjustment of the area facing away from the visible surface 3a can be achieved by means of suitable devices.
