摘要：A plant is proposed for the production of organic lenses inside mouldsconstituted by pairs of matching half-moulds kept spaced apart and linked with eachother by annular links of plastic material,inside whose cavity a suitable plastic material, tobe made polymerize before the drawing of the lenses, is intended to be introduced.After having been started and put under steady state running conditions, the plantcarries out automatically the following operations: assembling of the moulds withselected links; control of the centering of the two mould component parts; delivery ofthe assembled moulds to a filling machine, into a polymerization tank and into
maintenance tanks; removal of the links by tearing up from the moulds; transfer of thelink-free moulds, with the lenses formed inside them, into washing tanks; drawing of thelenses; delivery of the lenses to an optical check station, and discharging of the finishedlenses; recycling of the half-mould pairs. From the optical check of the formed lenses acommand is emitted for the selection of the links to be assembled with the respectivehalf-mould pairs. A closed-loop conveyor with sucker holding elements, intermittentlyrunning, brings the moulds to successive operating stations. Between the drawing stationand the stations for the assemblage of the half-mould pairs with the respective links,
intermediate stations are provided for the loading and the possible replacement of half-mould pairs.
