Abstract
A stacker device in an items processing system is a last station of a mail line. The stacker device has a receiving plate to receive flat items, a longitudinal alignment wall, graduated in at least two steps, at a rear side of the stacker device, and a stop wall that is arranged at the downstream end of the receiving plate.
Claims10
A stacker device comprising:
- a receiving plate onto which flat items proceed in a longitudinal movement direction between an upstream end and a downstream end of said receiving plate;
- an alignment wall proceeding along said longitudinal movement direction, said alignment wall being attached to and extending upwardly from said receiving plate;
- a stop wall situated at said downstream end of said receiving plate that stops movement of said flat items and thereby causes said flat items to accumulate in a stack on said receiving plate, adjacent to said alignment wall;
- and
- said alignment wall forming at least two steps therein that are stepped successively, starting from a step of said at least two steps that is closest to said receiving plate, so as to individually move toward said flat, items from step-to-step, with each of said at least two steps successively coming into contact with a flat item that is uppermost in a portion of said stack beneath that respective step as said stack accumulates in height, so that each of said steps limits an accumulated height of said flat items in the respective portion of said stack beneath that respective step, and thereby inhibits tilting of said stack away from said alignment wall.

- an alignment wall proceeding along said longitudinal movement direction, said alignment wall being attached to and extending upwardly from said receiving plate;
- a stop wall situated at said downstream end of said receiving plate that stops movement of said flat items and thereby causes said flat items to accumulate in a stack on said receiving plate, adjacent to said alignment wall;
- said alignment wall having at least two steps therein that are stepped individually toward said flat items, each of said steps limiting an accumulated height of said flat items in said stack;
- and
- each of said at least two steps of said alignment wall having at least one step attribute, selected from the group consisting of step depth and step height, that is uniform for each of said at least two steps.
