Machine for processing of lenses, preferably in plastic material

A machine for processing lenses, the machine comprising:

• a support structure;
• an apparatus for loading and storing raw lenses which comprises a lens exit portion and which is installed on said support structure;
• a lens cutting system which is installed on said support structure and which comprises:
• a first lens housing seat to receive one lens at a time;
• a first spindle-holder head for holding a cutting tool, the first spindle-holder head being positionable at said first lens housing seat by a first articulated arm connected to said support structure to perform cutting operations on said lens;
• a lens drilling-milling-engraving system installed on said support structure and comprising:
• a second lens housing seat to receive one lens at a time;
• and a second spindle-holder head for holding at least one tool for drilling, milling, or engraving, the second spindle-holder head being positionable at said second lens housing seat by a second articulated arm connected to said support structure to perform drilling, milling, or engraving operations on said lens;
• a processed lens unloading zone which is installed on said support structure;
• a lens transfer apparatus which is configured to pick up one lens at a time from said loading and storage apparatus to bring the picked up lens sequentially into the first lens housing seat of said lens cutting system, into the second lens housing seat of said lens drilling-milling-engraving system, and into the processed lens unloading zone;
• and
• a management and control unit;
• wherein the lens exit portion, the first lens housing seat, the second lens housing seat, and said processed lens unloading zone constitute four operating stations of said machine;
• wherein said lens transfer apparatus comprises a turret having four suction-cup seats for transporting lenses, each of said four suction-cup seats being configured to receive a single lens at a given time, and
• wherein said lens transfer apparatus further comprises a first motor to rotate said turret about a turret axis so as to cyclically bring each suction-cup seat in sequence to said four operating stations of the machine, the four operating stations being arranged on a circumference centered on said turret axis in angular positions spaced 90° apart from each other.
