Abstract

L'invention concerne un dispositif de transfert d'élément de bouton au moyen duquel il est possible d'éliminer le coinçage ou l'échec de passage d'un élément de bouton. Le dispositif de transfert d'élément de bouton (100) transfère un élément de bouton (10) d'une source d'alimentation (70) à une unité de traitement (80). Le dispositif de transfert d'élément de bouton (100) comprend : un trajet linéaire supérieur (110) qui reçoit l'élément de bouton (10) depuis la source d'alimentation (70) ; un trajet linéaire inférieur (120) qui fournit l'élément de bouton (10) à l'unité de traitement (80) ; un trajet incurvé central (130) reliant les trajets linéaires supérieur et inférieur (110, 120) ; et un mécanisme d'alimentation individuel (140) pour fournir l'élément de bouton (10) au trajet incurvé central (130) un par un, tout en accumulant temporairement une pluralité d'éléments de bouton (10) dans le trajet linéaire supérieur (110). Le trajet incurvé central (130) permet à l'élément de bouton (10) fourni par le trajet linéaire supérieur (110) un par un d'être passé au trajet linéaire inférieur (130).
