Title
(EN) TRANSFER STAR-WHEEL FOR CONTAINERS OF THERMOPLASTIC MATERIAL
(FR) ÉTOILE DE TRANSFERT POUR CONTENANTS EN MATIÈRE THERMOPLASTIQUE
Abstract
(EN)
Transfer star-wheel (1) for containers (100) of thermoplastic material, comprising: a rotary carousel (2) bearing a plurality of supporting stations (S) for supporting containers (100) by their neck (100b), in each supporting station (S) being provided a pliers (3) hinged to the rotary carousel (2) at a hinge axis (AA) in such a way that it assumes at least a first configuration in which the pliers (3) is fixed, that means it cannot rotate about its hinge axis (AA), and a second configuration in which the pliers (3) can oscillate about its hinge axis (AA); a cam kinematic motion that is operatively active on each pliers (3) for maintaining it in the first configuration, characterized in that it comprises a reactivating device (8) for each pliers (3), that comprises elastic means (9, 10) operatively active on the pliers (3) to bring it from the second to the first configuration following an accidental event that deactivated the pliers.
(FR)
La présente invention concerne une étoile de transfert (1) pour contenants (100) en matière thermoplastique comprenant : un carrousel rotatif (2) portant une pluralité de stations de support (S) pour supporter des contenants (100) par leur col (100b), chaque station de support (S) étant pourvue d'une pince (3) articulée sur le carrousel rotatif (2) au niveau d'un axe d'articulation (AA) de manière à prendre au moins une première configuration dans laquelle la pince (3) est fixe, c'est-à-dire qu'elle ne peut pas se mettre en rotation autour de son axe d'articulation (AA), et une seconde configuration dans laquelle la pince (3) peut osciller autour de son axe d'articulation (AA) ; un mouvement cinématique de came qui est fonctionnellement actif sur chaque pince (3) pour la maintenir dans la première configuration, caractérisé en ce qu'il comprend un dispositif de réactivation (8) pour chaque pince (3), qui comprend des moyens élastiques (9, 10) fonctionnellement actifs sur la pince (3) pour l'amener de la seconde à la première configuration suite à un événement accidentel qui désactive la pince.
