A transfer unit for containers

摘要

Containers (2) are transferred from a first conveyor (8) operating at a first height to a second conveyor (10) operating at a second height by a rotary unit (5) equipped with a plurality of grippers (27) designed to take up and support each successive container (2) by the neck (4). The grippers (27) are carried by respective slides (21) mounted to corresponding vertical guide elements (16) making up the main frame (17) of the unit (5), on which they are made to move up and down cyclically by a first roller (44) following a first track (39) that extends around a fixed C-shaped tubular element (30), and by a second roller (46) running on a second track (41) presented by the top surface (42) of a sector rail (37) placed with the concave side directed toward the lateral opening (30a) in the C-shaped element (30). The tubular element (30) can be replaced in the event of a size changeover. <IMAGE>
