A rotating system to withdraw, to transport and to supply blanks, the system comprising:
- two rotating elements disposed opposite one another and spaced among them;
- a first sun shaft act to support and rotate the two rotating elements;
- a first planetary shaft and a second planetary shaft disposed coaxial among them, in which the first and the second planetary shafts are disposed parallel and radially spaced with respect to the first sun shaft, in which the first and the second planetary shafts are supported in a rotating manner by the first and the second rotating element, in which the first and the second planetary shafts are designed to move along a circular orbit around the first sun shaft;
- two first arms, in which the two first arms extend with radial orientation with respect to the first and respectively to the second planetary shafts, in which the two first arms have two respective proximal portions respectively fixed on the first and second planetary shafts;
- a third planet shaft, in which the third planet shaft is supported in rotating manner by respective distal portions of the respective two first arms;
- one or more second arms, in which the one or more second arms extend with radial orientation with respect to the third planet shaft, in which the one or more second arms have proximal portion fixed on the third planet shaft;
- one or more gripper means, in which the one or more gripper means are supported in proximity of the distal portions of the one or more second radial arms;
- first transmission means, in which the first transmission means are able to rotate the first and the second planetary shafts in the same direction with respect to their axis, in relationship of phase with respect to the rotation and to the angular positions of the two rotating elements;
- second transmission means, in which the second transmission means are able to rotate-oscillate the third planet shaft in independent manner with respect to the rotation and with respect to the angular positions of the two rotating elements and in an independent manner with respect to the rotation and with respect to the angular positions of the two planetary shafts;
- first actuator means able to rotate the first sun shaft;
- second actuator means able to rotate-oscillate the third planet shaft by the second transmission means;
- synchronizer means able to synchronize the first and the second actuator means.
