Machine for removing seeds

1. A machine for removing one or more seeds, comprising:

a rotating rod ( 11 ), that is movable between a first position, in which the rotating rod is found outside of a product (P), and a second position, in which the rotating rod is inserted in a product (P);

a curved knife ( 12 ), associated with the rotating rod ( 11 );

an adjusting mechanism ( 20 ) structured so as to adjust the second position of the rotating rod ( 11 ) with respect to at least one dimension of the product (P) being processed;

wherein the adjusting mechanism ( 20 ) is structured so as to adjust a length of a stroke of the rotating rod ( 11 ) between the first position and the second position, with respect to at least one dimension of the product (P) being processed;

wherein the adjusting mechanism ( 20 ) comprises:

a main support ( 21 ), that is movable with respect to a rest surface (R) of the product (P) for a pre-established work stroke between a main support initial position and a main support final position, with which the rotating rod ( 11 ) is associated slidably along an axial direction (Y);

a feeler ( 22 ), arranged to come into contact with an exterior of the product (P) without being driven into the product (P) and that is movable with respect to the main support ( 21 ) for a relative stroke having a length between a feeler initial position and a feeler final position;

a linkage mechanism ( 23 ), that connects the feeler ( 22 ) to the rotating rod ( 11 );

wherein the adjusting mechanism ( 20 ) adjusts the length of the stroke of the rotating rod ( 11 ) depending on, or as a function of, the length of the relative stroke of the feeler ( 22 ), and wherein the linkage mechanism ( 23 ) is structured to transmit to the rotating rod ( 11 ) a fraction or a multiple of the relative stroke between the feeler ( 22 ) and the main support ( 21 );

wherein the linkage mechanism ( 23 ) comprises at least one oscillating bar ( 24 ) that has:

a first constraint (A), at which it is rotatable with respect to the main support ( 21 ) about a first axis (Ra);

a second constraint (B), at which it is slidable with respect to the feeler ( 22 ) and can rotate about a second axis (Rb);

a third constraint (C), at which it is slidable with respect to the rotating rod ( 11 ) and can rotate about a third axis (Rc);

wherein the rotation axes (Ra, Rb, Rc) of the constraints (A, B, C) are parallel to each other.

2. The machine according to claim 1 , wherein the third constraint (C) is in an intermediate position between the first constraint (A) and the second constraint (B).

3. The machine according to claim 1 , wherein the third constraint (C) is associated with an attachment element ( 25 ) that is attached to the rotating rod ( 11 ) with respect to the movement along the axial direction (Y) and that permits rotation of the rotating rod ( 11 ) about an axis aligned with the axial direction (Y).

4. The machine according to claim 1 , comprising two oscillating bars ( 24 ) intersecting symmetrically with respect to the third constraint (C).

5. The machine according to claim 1 , wherein the curved knife ( 12 ) is movable with respect to the rotating rod ( 11 ) between an active position, in which it can operate on a product (P) removing a part thereof, and an inactive position, in which it cannot interact with the product (P).

6. The machine according to claim 1 , wherein the feeler ( 22 ) comprises a front plate ( 22 c ) having a concave surface effectively shaped to contact the exterior of the product (P).
