Abstract

L'invention concerne un dispositif de transport de contenants (2). L'aspect essentiel dudit dispositif réside dans le fait qu'au moins un élément coulisse (11) déplaçable radialement par rapport à l'axe de machine permet d'engager dans un mouvement de pivotement guidé de manière forcée le premier et le deuxième bras de préhension (5.1, 5.2) d'un préhenseur de contenant correspondant, ledit élément coulisse (11) présentant au moins une première surface de commande (12) servant à commander le premier bras de préhension (5.1) et au moins une deuxième surface de commande (13), séparée de la première, servant à commander le deuxième bras de préhension (5.2), lesdites au moins première et deuxième surfaces de commande (12, 13) étant conçues pour permettre le guidage forcé du bras de préhension respectif (5.1, 5.2) entre la position de préhension (GP) et la position de relâchement (FP).
