SEPARATING DEVICE FOR SEPARATING A MATERIAL LAYER BY MEANS OF A CUTTING JET USING AN ARTICULATED CUTTING HEAD WITH A TOUCH CONTACTOR

Die Trennvorrichtung zum Trennen einer Materialschicht (70) mittels eines Schneidstrahls umfass einen Schneidkopf (40), aus welchem beim Trennvorgang der Schneidstrahl austritt, ein Gelenk (50) mit sphärischen Flächen (52, 53) zur schwenkbaren Anordnung des Schneidkopfes (40) und eine Antriebseinrichtung zum Schwenken des Schneidkopfes (40). Gemäss einem ersten Aspekt ist der Schneidkopf um ein Schwenkzentrum (55) schwenkbar, das von den sphärischen Flächen (52, 53) umgeben ist, so dass es innerhalb des Gelenkes (50) angeordnet ist. Gemäss einem zweiten Aspekt umfasst die Trennvorrichtung einen Taster (30) zum Erfassen des Abstandes zwischen Schneidkopf (40) und Oberfläche (70a) der Materialschicht (70). The device for the separation of a material layer (70) by a cutting jet, comprises a cutting head (40) from which the cutting jet exits during the separation process, a joint (50) with spherical surface (52, 53) for pivotable arrangement of the cutting head, a drive device for pivoting the cutting head, and a button (30) for detecting the interval between the cutting head and the surface of the material layer. The button is held on the cutting head so that both are pivotable together. The button has a curved surface, which is mounted on the material layer.

The button is held on the cutting head so that both are pivotable together. The button has a curved surface, which is mounted on the material layer. The button is coupled on a button drive by which the button is adjustable in longitudinal direction of the cutting head and/or is pressed with an adjustable power against the surface of the material layer. The button has a passage opening for the passage of the cutting jet. The second joint comprises a spherical surface, which is arranged to the first joint. The second joint is adjustable in related to the first joint in a plane. The second joint has an axial guidance, which has a rifle that is adjustable in related to a ball body of the second joint. The second joint is held in a cross slide. The drive device comprises a linear drive. A position senso
