Multi-Mode Unstacker Device for Unstacking Mailpieces

摘要

A mailpiece unstacker device comprises a feed magazine for moving the mailpieces in a stack and on edge in a certain direction towards an unstacker head. It is provided with materials sensors for delivering signals indicating that a current mailpiece has a cover made of a plastics material and/or includes a metal material. A control unit forces the feed magazine and the unstacker head to operate as a function of the signals generated by the sensors so that the mailpieces are presented facing the unstacker head in positions that are inclined backwards to various extents.
