  • Patent number: 4884386
    Abstract: A system for recovering, selecting and recycling empty containers returned after use which includes two specific sequences. In the first sequence, a container (4) passes a door (2) to remove material of a different type, while the accepted product activates a microswitch (9) for counting and activating a warming device to blow in hot air onto the same material which is thus softened; the container is then pushed between a motor driven heated pressing roll (18) with tension supplied by sliding contacts (22) to carry out a compact and permanent pressing by using pressing-welding points and another inertia roller (19). Knives (24) cooperate with the two rollers to ensure the separation. In the second sequence or selection phase, recovered bodies (29), are applied from hopper (30) and fall onto a feeding system with vibrating canals, to maintain the containers individually; photocells (34) check that no superpositions occur.
