Feeder for robots, automation means and the like

1. A feeder for robots and automation means, comprising a frame that has a supporting bed for the parts to be fed and vision means for recognizing said parts to be fed, wherein said supporting bed is connected to rotation means for rotation about a direction that is substantially perpendicular to the plane of arrangement of said parts to be fed, the feeder further comprising impulse generation means which are connected to said frame and operate on said supporting bed, wherein the impulses activated by said impulse generation means are substantially normal with respect to the plane of arrangement of the objects to be gripped, so as to make the part or parts jump that lie proximate to the point of contact with said supporting bed changing completely the spatial orientation thereof.

2. The feeder according to claim 1 , wherein said frame comprises a base plane, which supports supporting columns for a supporting ring for said supporting bed.

3. The feeder according to claim 2 , wherein said vision means comprise lighting means associated with said frame.

4. The feeder according to claim 3 , wherein said lighting means comprise a lighting assembly, which is supported by a supporting frame associated with said base plane.

5. The feeder according to claim 1 , wherein said rotation means comprise a motor, which is connected to said frame and is dependent on the characteristics of said parts to be fed.

6. The feeder according to claim 5 , wherein said direction which is substantially perpendicular to said plane of arrangement of said parts to be fed coincides with an axis of a driving shaft of said motor.

7. The feeder according to claim 6 , wherein said supporting bed is jointly associated to said driving shaft.

8. The feeder according to claim 6 , further comprising means for gripping at least one of said parts to be gripped, which are controlled by said vision means.

9. The feeder according to claim 8 , wherein said grip means comprise a movable arm, which has an engagement clamp, said movable arm being retained for rotation about a pivoting direction that is parallel to said axis and being further adapted to move along a direction which is normal to said supporting bed.

10. The feeder according to claim 1 , wherein said impulse generation means comprise a bounce magnet, which is connected to said frame and operates on an internal surface of said supporting bed.

11. The feeder according to claim 10 , wherein said impulse generation means comprise a movable slider for the movement of said bounce magnet, which is connected to said base plane.

12. The feeder according to claim 10 , wherein said impulse generation means comprise a pneumatically-operated actuator, which is connected to said frame and operates on the internal surface of said supporting bed.

13. A method for gripping at least one part of a feeder of a robot, comprising the steps of loading the supporting bed of said feeder with parts to be gripped, choosing at least one of said parts to be gripped by vision means for recognition of the parts to be fed, said vision means being connected to said feeder, and picking up said at least one of said parts to be gripped, wherein during the succession of said steps said parts to be gripped move continuously, further comprising a step for varying a spatial orientation of said parts to be gripped on said supporting bed, said step of varying the spatial orientation comprising a scattering of said parts to be gripped by the actuation of impulse generation means, wherein the impulses activated by said impulse generation means are substantially normal with respect to the plane of arrangement of the objects to be gripped, so as to make the part or parts jump that lie proximate to the point of contact with said supporting bed changing completely the spatial orientation thereof.

14. The method according to claim 13 , wherein the loading of said supporting bed with said parts to be gripped is performed continuously.
