Abstract:

A corrugated cardboard sheet feeding apparatus, which comprises: an upstream-side conveying unit (24A) which conveys a corrugated cardboard sheet (100a) mounted on delivery rollers (15b); and a downstream-side conveying unit (24B) which is adjacent to the downstream side of the upstream-side conveying unit (24A) and conveys, to a sheet processing unit, the corrugated cardboard sheet (100a) delivered from the upstream-side conveying unit (24A). The downstream-side conveying unit (24B) has: a downstream-side suction unit (21A) which has openings (21a) facing a sheet conveyance path; and feed rollers (11b) with a portion of the outer peripheral surfaces thereof protruding towards the sheet conveyance path, which are accommodated in the downstream-side suction unit (21A). The distance (L1) between the downstream ends (21b) of the openings (21a) and the axis (CL1) of the most-downstream-side delivery rollers (15b) is set to be not larger than the maximum range of the distance between the conveyance rollers of the sheet processing unit.
