Abstract

L'invention concerne un dispositif de déplacement (200) conçu pour un système de manipulation (250), comprenant un mécanisme d'articulation (201) sur lequel le système de manipulation (250) est reçu, ce système de manipulation (250) pouvant être déplacé au moyen du mécanisme d'articulation (201) entre une première position (202) et une deuxième position (203). À cet effet, un dispositif de précontrainte (204) coopère avec le mécanisme d'articulation (201) et/ou le système de manipulation (250) pour amortir le poids du mécanisme d'articulation (201) et/ou système de manipulation (250) pendant le déplacement du système de manipulation (250) entre la première position (202) et la deuxième position (203). Lors du procédé pour déplacer un système de manipulation (250) au moyen d'un tel dispositif de déplacement (200), le dispositif de précontrainte (204) amortit le poids du système de manipulation (250) par un déplacement entre la première position (202) et la deuxième position (203), de sorte qu'une application de force continue et réduite soit nécessaire pour mouvoir le système de manipulation (250). La machine à emballer (1) conçue pour remplir des sacs de produit, et en particulier de produits en vrac, comprend un module de remplissage (100) équipé d'un ajutage de remplissage (101), un tel dispositif de déplacement (200) et au moins un système de manipulation (250).
