PILING MACHINE FOR FLAT ITEMS

摘要

The invention relates to a stacking machine for stacking flat items which comprises
a first stacking table (18) which descends from a position higher than the infeed end (4,5) to a stacking position, the separation of a constant flow of flat items in consecutive bundles occurring with this movement, and on which table flat items (12) received from an infeed end (4, 5) are subsequently stacked to form bundles (33B, 33D), connected to first displacement means (24) which displace it between a stacking position in which the first stacking table (18) receives flat items (12) and an unloading position in which the bundles (33B, 33D) are transferred to the unloading means (36);
a second stacking table (19) which descends from a position higher than the infeed end (4,5) to a stacking position, the separation of a constant flow of flat items in consecutive bundles occurring with this movement, and on which table flat items (12) received from the infeed end (4, 5) are subsequently stacked to form bundles (33A, 33C), connected to second displacement means (24') which displace it between a stacking position in which the second stacking table (19) receives flat items (12) and an unloading position in which the bundles (33B, 33D) are transferred to the unloading means (36),
unloading means (36) for transferring the bundles (33A, 33B, 33C, 33D) from the first or second stacking table (18, 19) to a fixed unloading table (46);
coupling means (41, 42) for coupling the unloading means (36) alternatively to the first stacking table (18) or to the second stacking table (19).
