摘要

Apparatus with high level of autonomy for the cyclical feeding of a large flow of trays, boxes or other die-cut corrugated cardboard sheets (F) for packaging, to a conveyor line (1) that feeds in phase these die-cut corrugated cardboard sheets to a high production continuous packaging machine, characterized in that it comprises two or more stores (2, 2', 2") containing the die-cut corrugated cardboard sheets (F) positioned laterally with respect to or above an initial portion of the conveyor (1) or auxiliary conveyor means associated therewith, and in that it comprises cyclical first transfer means (5, 505) for extracting respective die-cut corrugated cardboard sheets (F) from each of the stores (2, 2', 2") and for feeding them in head to tail arrangement and in phase on to the conveyor which is thus cyclically resupplied with two or more die-cut corrugated cardboard sheets at a time, in order to provide ample opportunity for adaptation to the production requirements of the continuous packaging machine which it serves, while also decreasing the operating frequency of the cyclical first transfer means (5, 505) and consequently increasing the load capacity and overall autonomy of operation of the stores (2, 2', 2").
