Abstract

L'invention concerne un dispositif de manipulation de piles d'une machine à imprimer une feuille recto et une feuille verso. L'invention vise à créer un dispositif de manipulation de piles pour une machine à imprimer une feuille recto et consécutivement verso. Pour ce faire, les piles sont placées sur des chariots transporteurs, lesquels sont affectés à un niveau d'empilage commun (10) et, dans les zones latérales de la pile de feuilles du margeur (1) et de la pile de sortie (11), est disposé de façon symétrique à l'axe longitudinal de la machine respectivement un bras en porte à faux doté d'un mécanisme d'entraînement vertical et situé dessous le chariot transporteur concerné. A côté de chaque bras en porte à faux, une unité de transport linéaire (8) est disposée dans le sens de l'axe longitudinal de la machine et, à côté de l'unité de transport linéaire (8), est disposée une voie pour les rouleaux des chariots transporteurs de la pile. Sur l'axe longitudinal de la machine se trouve le pivot d'une table rotative affectée aux rouleaux du chariot transporteur de la pile de sortie (11) et libérant la voie dans sa position de repos. A côté de chaque bras en porte à faux dans le sens opposé de l'axe longitudinal de la machine, se trouve au-dessus de la pile respectivement une voie de roulement supérieure servant à amener le chariot transporteur de la pile du margeur (1) en position d'exploitation de la pile de sortie (11).
