Stacker device for stacking flats, a storage device for storing postal flats, and a postal sorting machine

摘要

A stacker device (1) for stacking flats (100) on edge, which device includes a stacking support (2) that extends along a certain stacking axis (D2) for storing flats (100) on edge and in a stack, which flats are inserted successively onto said stacking support (2), a stacking actuator (4) for guiding each flat (100) to be stacked along an insertion axis (D1) transverse to the stacking axis (D2), and for inserting it at the back of said stack of flats (100), said stacking support (2) being mounted to move relative to the stacking actuator (4) along the stacking axis (D2), and said stacker device (1) including impulse means (9) synchronized with the stacking actuator (4) so as to move the stacking support (2) in translation by applying an impulse along the stacking axis (D2) when a flat (100) is inserted at the back of said stack of flats (100). A storage device and a postal sorting machine including such a stacker device (1).

主权项

1. A stacker device for stacking flats on edge, which device comprises:
a stacking support that extends along a certain stacking axis for storing flats on edge and in a stack, which flats are inserted successively onto said stacking support; a stacking actuator designed for guiding each flat to be stacked along an insertion axis transverse to the stacking axis, for inserting it at a first end of said stack of flats, and for pushing said first end of the stack while the flat is being inserted along the stacking axis; and a retaining element that is mounted to move along the stacking axis and that is designed to retain the stack of flats at a second end of the stack that is opposite from said first end, while pushing the stack of flats towards the stacking actuator as the stack of flats is being formed; said stacker device being characterized in that said stacking support is mounted to move along the stacking axis in both directions, and in that said stacker device includes impulse means synchronized with the stacking actuator so as to move said stacking support by direct contact in the direction along said stacking axis that goes away from the stacking actuator, said impulse means including return means for bringing the stacking support back along the stacking axis towards the stacking actuator.
