Abstract: An apparatus for loading and accumulating semi-finished plate-like pieces, in particular lenses, includes a support structure and a piece warehouse which is associated with the support structure for moving the pieces from a piece inlet portion to a piece outlet portion along a warehouse axis. The warehouse includes augers extending parallel to the warehouse axis along respective longitudinal axes and are arranged around the warehouse axis to jointly delimit transverse seats with respect to the warehouse axis. Each seat accommodates a semi-finished plate-like piece. A system coordinates positioning of the augers for varying a distance of each auger from the warehouse axis to vary a radial dimension of the transverse seats. A system rotates each auger around the relevant longitudinal axis in a synchronized manner to cause movement of the pieces parallel to the warehouse axis from the inlet portion to the outlet portion.

Abstract: A confinement cabin has a load-bearing structure, confinement walls connected to the load-bearing structure to delimit an inner space of the cabin, an access opening to the inner space, and a door connected to the load-bearing structure to close the access opening. The door is movable in opening and closing with a pivoting-tilting movement and has a movable arm which at a first end is rotationally connected to the load-bearing structure to rotate around a hinging axis, and a closing panel rotationally connected to a second end of the movable arm to rotate around a tilting axis. Rotation of the panel around the tilting axis is synchronized with rotation of the movable arm around the hinging axis by an elastic transmission system between a first pulley coaxial to the hinging axis and a second pulley coaxial to the tilting axis. Rotation of the panel around the tilting axis is in the opposite direction to rotation of the movable arm around the hinging axis.
