Title
(EN) INSTALLATION FOR THE MANUFACTURE OF CONTAINERS FROM A PREFORM AND METHOD OF CONTROLLING THE BLOW-MOULDING MEANS OF SUCH AN INSTALLATION
(FR) INSTALLATION POUR LA FABRICATION DE RECIPIENTS A PARTIR D'UNE PREFORME ET PROCEDE DE COMMANDE DES MOYENS DE SOUFFLAGE D'UNE TELLE INSTALLATION
Abstract
(EN)
The invention relates to a method of controlling an installation for the manufacture of containers by blow moulding or by stretch-blow moulding from a preform, the installation comprising at least one moulding unit (42) equipped with a control device capable of controlling, by displacement, at least one nozzle (56) that is associated with a mould (46), the nozzle (56) being movably mounted so as to be able to move vertically between a top position and a bottom position in which, the mould (46) being in a closed position, the nozzle (56) covers at least one flow opening (88) that comprises an upper horizontal wall (90) of the mould, characterized in that the method of control involves at least a first step comprising, the mould (46) being in a closed position, systematically controlling the vertical descent of the nozzle (56) towards the bottom position independently of the presence or absence of a preform in the mould (46) so that, both when the installation is operating and when it is at rest, the internal volume of the mould (46) is isolated in order to avoid the risk of airborne particulate contamination.
(FR)
L'invention concerne un procédé de commande d'une installation pour la fabrication de récipients par soufflage ou par étirage-soufflage à partir d'une préforme, l'installation comportant au moins une unité de moulage (42) équipée d'un dispositif de commande apte à commander en déplacement au moins une tuyère (56) qui est associée à un moule (46), la tuyère (56) étant montée mobile verticalement entre une position haute et une position basse dans laquelle, le moule (46) étant en position fermée,la tuyère (56) coiffeau moins un orifice (88) de passage que comporte une paroi supérieure horizontale (90) du moule, caractérisé en ce que le procédé de commande comporte au moins une première étape consistant, le moule (46) étant en position fermée, à commander systématiquement la descente verticale de la tuyère (56) vers la position basse indépendamment de la présence ou de l'absence d'une préforme dans le moule (46) de manière que, tant en fonctionnement qu'à l'arrêt de l'installation, le volume intérieur du moule (46) soit isolé pour éviter les risques de contaminations particulaires aéroportées.
