<p>Capping unit (100), comprising one or more capping heads (8), for screwing caps (6) or capsules onto the filled article or container, said unit operating on at least one motorized transport line (4) for advancing one or more rows of objects to be capped. The system provides for screwing during at least one linear movement of the containers, i.e. in pursuit, using threaded caps or capsules. A cap feeding and picking-up group (13, 14, 15, 16, 20) can be present. The apparatus comprises at least one screw capping group (3) with a possible upstream filling group (2) operating through a three-axis motor system with linear motors and/or brushless motors for the rotation of recirculating ball screws or toothed belts. As an alternative, the apparatus operates through an anthropomorphic multi axis robot. Both capping and filling groups, are synchronized by means of a couple of robots, or by a shared three-axis motor system, in order to position said groups according to a parallel, vertical and approaching direction with respect to the line for transporting objects.</p> |
