Abstract

L'invention concerne la fabrication des préformes en polyéthylène téréphtalate (PET) pour la fabrication de bouteilles par soufflage-étirage. La zone de déformation (1) de la préforme, située sous la collerette de retenue (2) est munie de plusieurs cannelures longitudinales (3). Les flancs (4) de ces cannelures déterminent une surface développée de la zone déformable supérieure de 20% à la surface développée par le même diamètre primitif d'une préforme cylindrique pour une même longueur de cette zone. Cette augmentation de surface développée permet de réduire dans la même proportion de 20% l'épaisseur de matière dans la zone déformable (1). Les extrémités des cannelures (5) situées sous la zone de retenue de la collerette (2) sont rayonnées et assurent le centrage de la préforme dans le guide d'alimentation de la machine d'étirage-soufflage. La réduction de l'épaisseur de la préforme permet de réduire le cycle de refroidissement lors de l'injection et d'augmenter les cadences de production.The invention relates to the manufacture of polyethylene terephthalate (PET) preforms for the manufacture of bottles by blow-drawing. The deformation zone (1) of the preform, located under the retaining flange (2) is provided with several longitudinal grooves (3). The flanks (4) of these grooves determine a developed surface of the deformable zone 20% greater than the developed surface by the same pitch diameter of a cylindrical preform for the same length of this zone. This increased surface area makes it possible to reduce the thickness of material in the deformable zone (1) in the same proportion by 20%. The ends of the grooves (5) located under the retaining zone of the flange (2) are radiated and ensure the centering of the preform in the feed guide of the stretch-blow molding machine. The reduction of the thickness of the preform makes it possible to reduce the cooling cycle during the injection and to increase the production rates.

Description

-1- L'invention concerne la fabrication des préformes en polyéthylène téréphtalate (PET) pour la fabrication de bouteilles par soufflage-étirage. La préforme se présente habituellement sous forme d'un tube cylindrique fermé à une extrémité et ouvert à l'autre extrémité qui forme le col de la préforme muni d'une collerette de retenue pour le convoyage dans la machine de soufflage-étirage. La partie inférieure de la préforme située sous la collerette de retenue constitue la zone déformable lors de l'opération de soufflage-étirage. Cette partie est d'une épaisseur appropriée pour permettre la mise en forme de la bouteille en fonction de la taille et du poids souhaités de ladite bouteille. Le diamètre primitif de la préforme dans la zone de déformation est généralement de l'ordre de quatre millimètres inférieurs au diamètre de la collerette de retenue, et l'épaisseur de matière dans cette zone de déformation définit la masse de matière nécessaire à l'opération de soufflage-étirage.The invention relates to the manufacture of polyethylene terephthalate (PET) preforms for the manufacture of bottles by blow-drawing. The preform is usually in the form of a cylindrical tube closed at one end and open at the other end which forms the neck of the preform provided with a retaining flange for conveying in the blow-molding machine. The lower part of the preform located under the retaining collar constitutes the deformable zone during the blow-drawing operation. This portion is of a suitable thickness to allow the shaping of the bottle according to the desired size and weight of said bottle. The pitch diameter of the preform in the deformation zone is generally of the order of four millimeters smaller than the diameter of the retaining flange, and the thickness of material in this deformation zone defines the mass of material required for the operation. stretch blow molding.

Cette épaisseur pénalise fortement le cycle de refroidissement de la préforme lors de l'injection et influence de manière négative la cadence de production desdites préformes. La présente invention se propose de réduire l'épaisseur de paroi de la préforme dans la zone de déformation par soufflage-étirage, sans modifier le diamètre primitif de la préforme et sans modifier la dimension hors tout de ladite préforme tout en conservant la masse de matière nécessaire au soufflage-étirage. -2- Dans ce but, l'invention concerne une préforme du genre indiqué en préambule, caractérisée en ce que la zone cylindrique déformable située sous la collerette de retenue est munie de cannelures longitudinales dont les flancs contribuent à définir une surface développée de la zone déformable, supérieure de l'ordre de 20% par rapport à la surface développée par la forme cylindrique habituelle des préformes. Cette augmentation de la surface développée de l'ordre de 20%, permet de réduire dans la même proportion de 20%, l'épaisseur de la paroi dans la zone déformable tout en conservant la même masse de matière nécessaire au façonnage de la bouteille. Cette réduction de l'épaisseur de matière de la préforme permet de réduire le temps de refroidissement lors de l'injection et augmente de manière significative les cadences de production des préformes injectées. La présente invention et ses avantages apparaîtront mieux dans la description suivante d'un mode de réalisation donné à titre d'exemple non limitatif, en référence aux dessins annexés, dans lesquels : La figure 1 représente une vue de face de la préforme. La figure 2 est une vue en coupe de la zone déformable de la préforme. En référence aux figures 1 & 2, la zone de déformation (1) située sous la collerette de retenue (2) est munie de plusieurs cannelures longitudinales (3). Les flancs (4) de ces cannelures déterminent une surface développée de la zone déformable supérieure -3- de 20% à la surface développée par le diamètre primitif d'une préforme cylindrique pour une même longueur de cette zone. Les extrémités des cannelures (5) situées sous la zone de retenue de la collerette (2) sont rayonnées et assurent le centrage de la préforme dans le guide d'alimentation de la machine de soufflage-étirage. Les sommets des cannelures (6) et les pieds des cannelures (7) sont rayonnés en fonction de l'épaisseur de matière pour maintenir ladite épaisseur matière (8) constante dans toute la zone de déformation par soufflage-étirage. La surface développée de la zone déformable étant augmentée de l'ordre de20%, il est possible de réduire l'épaisseur de matière plastique dans cette zone de 20% tout en conservant la même masse de matière déformable par soufflage-étirage, le même diamètre primitif et la même longueur hors tout de la préforme. Cette réduction de l'épaisseur de la paroi dans la zone déformable de la préforme permet la réduction du temps de refroidissement lors de l'injection et d'augmenter les cadences de production des préformes. Lors de l'opération de soufflage-étirage, les cannelures (4) se déploient radialement et longitudinalement, en même temps que le reste de la zone déformable, pour façonner la bouteille contre les parois du moule.20This thickness strongly penalizes the cooling cycle of the preform during injection and adversely influences the rate of production of said preforms. The present invention proposes to reduce the wall thickness of the preform in the stretch-blow deformation zone, without modifying the original diameter of the preform and without modifying the overall dimension of said preform while preserving the mass of material. necessary for blow molding. To this end, the invention relates to a preform of the kind indicated in the preamble, characterized in that the deformable cylindrical zone located under the retaining flange is provided with longitudinal grooves whose flanks contribute to define a developed surface of the zone. deformable, superior of the order of 20% relative to the surface developed by the usual cylindrical shape of the preforms. This increase of the developed surface of the order of 20%, makes it possible to reduce in the same proportion by 20%, the thickness of the wall in the deformable zone while retaining the same mass of material necessary for shaping the bottle. This reduction in the material thickness of the preform makes it possible to reduce the cooling time during injection and significantly increases the production rates of the injected preforms. The present invention and its advantages will appear better in the following description of an embodiment given by way of non-limiting example, with reference to the accompanying drawings, in which: Figure 1 shows a front view of the preform. Figure 2 is a sectional view of the deformable zone of the preform. Referring to Figures 1 & 2, the deformation zone (1) located under the retaining collar (2) is provided with a plurality of longitudinal grooves (3). The flanks (4) of these grooves determine a developed surface of the deformable zone greater than 20% to the surface developed by the pitch diameter of a cylindrical preform for the same length of this zone. The ends of the splines (5) located under the retaining zone of the flange (2) are radiated and ensure the centering of the preform in the feed guide of the blow molding machine. The tops of the grooves (6) and the feet of the grooves (7) are radiated according to the thickness of material to maintain said material thickness (8) constant throughout the stretch blow-deformation zone. The developed surface of the deformable zone being increased by about 20%, it is possible to reduce the thickness of plastic material in this area by 20% while maintaining the same mass of deformable material by blow-drawing, the same diameter primitive and the same overall length of the preform. This reduction in the thickness of the wall in the deformable zone of the preform makes it possible to reduce the cooling time during the injection and to increase the rates of production of the preforms. During the stretch-blow operation, the flutes (4) extend radially and longitudinally, along with the remainder of the deformable zone, to shape the bottle against the walls of the mold.
