Title
(DE) OFEN ZUM KONDITIONIEREN VON VORFORMLINGEN
(EN) FURNACE FOR CONDITIONING PREFORMS
(FR) FOUR DE CONDITIONNEMENT DE PRÉFORMES
Abstract
(DE)
Beschrieben wird ein Ofen vom Rundläufertyp zum Konditionieren von Vorformlingen, insbesondere für das Streckblasen von Kunststoffgefäßen, mit einem Heizrad, an dem mehrere Heizmodule zum Erwärmen je eines Vorformlings angeordnet sind. Dadurch, dass an den Heizmodulen eine Temperaturmesseinrichtung zum Messen mindestens einer Temperatur des Vorformlings und/oder der Heizkammer vorgesehen ist, und dass der Ofen ferner eine Steuereinrichtung zum Ansteuern der Heizmodule auf Grundlage der gemessenen Temperatur umfasst, kann eine reproduzierbare Erwärmung der Vorformlinge durch Regelung der einzelnen Heizmodule gewährleistet werden.
(EN)
The invention relates to a rotary-type furnace for conditioning preforms, in particular for the stretch blow moulding of plastic receptacles, said furnace comprising a heating wheel on which a plurality of heating modules, each for heating one preform, are arranged. Reproducible heating of said preforms by the regulation of the individual heating modules is guaranteed by the provision of a temperature measuring device for measuring at least one temperature of the preform and/or of the heating chamber, on the heating modules, and by the fact that the furnace additionally comprises a control device for actuating the heating modules on the basis of the temperatures that have been measured.
(FR)
L'invention concerne un four de type à plateau tournant destiné au conditionnement de préformes, notamment pour l'étirage-soufflage de contenants en plastique, ce four comportant un plateau chauffant sur lequel sont disposés plusieurs modules chauffants qui chauffent chacun une préforme. Une mise en température reproductible des préformes par régulation de chaque module chauffant est rendue possible par le fait que les modules chauffants sont dotés d'un dispositif de mesure thermique pour mesurer au moins une température de la préforme et/ou de la chambre de chauffe, et que le four est en outre pourvu d'un dispositif de commande pour piloter les modules chauffants sur la base de la température mesurée.
