Abstract

L'invention concerne une machine d'emballage de fabrication de sacs grâce à laquelle le taux de remplissage d'articles peut être augmenté même en aval d'un mécanisme d'étanchéité latéral. La présente machine d'emballage de fabrication de sacs emballe des articles (A) déchargés à partir d'une machine de décharge d'articles dans un sac (W) obtenu par moulage d'un film en une forme tubulaire. La machine d'emballage de fabrication de sacs comprend un mécanisme d'étanchéité latéral, un mécanisme de déplacement et une unité de commande. Le mécanisme d'étanchéité latéral effectue une première opération pour pincer un film à partir d'une direction (direction horizontale H) croisant une direction de transport et sceller le film. Le mécanisme de déplacement déplace le mécanisme d'étanchéité latéral. L'unité de commande commande le mécanisme de déplacement et entraîne l'exécution d'une opération de vibration pour faire vibrer le mécanisme d'étanchéité latéral ayant terminé la première opération et transmettre une vibration aux articles (A) dans un tube de film (FT).
