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

A buffer apparatus 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 comprising:

• a support structure;
• a plurality of inclined accumulation planes, arranged one over the other, dedicated to an accumulation of cores, in the shape of logs, for toilet rolls or absorbent paper rolls or similar paper or absorbent materials;
• a mechanism for feeding the cores, operatively associated with the inclined accumulation planes in order to provide the inclined accumulation planes with the cores being fed by a feeding line not belonging to the buffer apparatus;
• a first transferring device for transferring cores fed by the feeding mechanism to at least one of the inclined accumulation planes, the first transferring device being operatively interposed between the feeding mechanism and the inclined accumulation planes and being movable, independent of any movement of the mechanism for feeding the cores, among each of the plurality of inclined accumulation planes in order to transfer the cores being fed to the respective inclined accumulation plane, the first transferring device providing a path between the mechanism for feeding the cores and one of the plurality of inclined accumulation planes;
• a discharge mechanism operatively associated with the inclined accumulation planes in order to discharge the accumulated cores from the respective inclined accumulation plane;
• and
• a second transferring device for transferring cores that are present in at least one of the inclined accumulation planes to the discharge mechanism, the second transferring device being operatively interposed between the inclined accumulation planes and the discharge mechanism and being movable from an inclined accumulation plane to another inclined accumulation plane in order to transfer the accumulated cores to the discharge mechanism.
