DEVICE FOR THE STACKING OF PLANAR OBJECTS ALONG AN EDGE, AND MAIL-SORTING MACHINE PROVIDED WITH LEAST ONE SUCH DEVICE

摘要

The invention relates to a stacking device including a support shelf (24,24') on which a stack (P) of planar objects (OrOn) is formed, said objects being inserted and pushed back to the edge one by one in a main direction (D) so as to bear against an element (18) for retaining the stack, which is provided at the front end of said stack. The support shelf (24, 24') is mounted so as to be freely translatable in the main direction (D) with the movement thereof being synchronized with the retaining element (18) in said direction, which makes it possible to impart great stability to the stack thus formed. The retaining element (18) is moreover movable with respect to the frame (10) and associated with means arranged such that the frame applies a return force on the stack of planar objects (OrOn) so as to retain said objects. The invention also relates to a mail-sorting machine provided with at least one such stacking device.
