Buffer apparatus for cores made of paper material, for production lines of toilet rolls or absorbent paper rolls or similar paper or absorbent materials

Buffer apparatus (1) for cores made of paper material, for production lines of toilet rolls or absorbent paper rolls or similar paper or absorbent materials, the buffer apparatus (1) comprising:

• a support structure (2);
• a plurality of inclined accumulation planes (5), arranged one over the other, dedicated to the accumulation of cores, in particular in the shape of logs, for toilet rolls or absorbent paper rolls or similar paper or absorbent materials;
• a mechanism (6) for feeding the cores, operatively associated with the inclined accumulation planes (5) in order to provide the latter with the cores being fed by a feeding line not belonging to the buffer apparatus (1);
• a first transferring device (11) for transferring cores fed by the feeding mechanism (6) to at least one of the inclined accumulation planes (5), the first transferring device (11) being operatively interposed between the feeding mechanism (6) and the inclined accumulation planes (5) and being movable from an inclined accumulation plane (5) to another inclined accumulation plane (5) in order to transfer the cores being fed to the latter;
• a discharge mechanism (16) operatively associated with the inclined accumulation planes (5) in order to discharge the accumulated cores from the latter;
• a second transferring device (21) for transferring cores that are present in at least one of the inclined accumulation planes (5) to the discharge mechanism (16), the second transferring device (21) being operatively interposed between the inclined accumulation planes (5) and the discharge mechanism (16) and being movable from an inclined accumulation plane (5) to another inclined accumulation plane (5) in order to transfer the accumulated cores to the discharge mechanism (16).
