Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Erwärmen von Vorformlingen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device to warm up of preforms according to the generic term of claim 1.
Es sind bereits derartige Vorrichtungen
bekannt, bei denen die Kühlschilde
aus Metall bestehen und mit Kanälen
versehen sind, durch die eine Kühlflüssigkeit
zirkuliert (
Der Erfindung liegt die Aufgabe zu Grunde bei einer vorrichtung der eingangs genannten Art mit geringen Herstellungs- und Betriebskosten eine optimale Abschirmung des nicht zu verformenden Kopfbereichs der Vorformlinge zu realisieren.The invention is based on the object Basically in a device of the type mentioned with low Manufacturing and operating costs an optimal shielding of the to realize the deformable head area of the preforms.
Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the solved in the characterizing part of claim 1.
Es hat sich überraschenderweise gezeigt, dass ein im wesentlichen aus Keramik bestehender Kühlschild ohne Innenkühlung eine unzulässige Bestrahlung der Vorformlinge zuverlässig verhindern kann. Auf Grund des hohen Reflexionsgrads für Infrarotstrahlung und der schlechten Wärmeleitfähigkeit von Keramikmaterial stellt sich an der den Heizstrahlen abgewandten Seite des Kühlschilds in der Regel keine kritische Temperatur ein, die die Vorformlinge negativ beeinflussen könnte. Auch kann der keramische Kühlschild auf Grund seiner Temperaturunempfindlichkeit sehr dicht an den Heizstrahlern angeordnet werden, bzw. ein Teil des Gehäuses für die Heizstrahler bilden, wodurch sich eine optimale Abschattung ergibt. Kondenswasser tritt nicht auf.Surprisingly, it has been shown that a cooling shield consisting essentially of ceramic without internal cooling unacceptable Can reliably prevent irradiation of the preforms. Because of of high reflectance for Infrared radiation and the poor thermal conductivity of ceramic material stands on the side of the cooling shield facing away from the heating rays usually no critical temperature that negatively affects the preforms could affect. The ceramic cooling shield can also be used due to its insensitivity to temperature, very close to the radiant heaters be arranged, or form part of the housing for the radiant heater, which results in optimal shading. Condensation occurs not on.
Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous further developments of Invention are the dependent claims refer to.
