Abstract
An unstacker device comprises a floor and a retaining paddle that are designed to move a stack of mailpieces from a feed magazine towards an unstacker head under the action of a monitoring and control unit as the mailpieces are being unstacked from the front of the stack. The device further comprises a vision system suitable for forming a profile digital image of said stack of mailpieces in the magazine, and said unit is arranged to evaluate a certain inclination of the mailpieces in the stack on the basis of said profile image and to cause the floor and the paddle to move so as to present the mailpiece at the front of the stack in a satisfactory position on edge so that it can be unstacked by the unstacker head.
