Rotary conveyor with suction and change of pitch for transferring containers

摘要

The conveyor comprises a plurality of sliding runners (5) coupled to guiding elements (2) that are fixed to a rotary platform (1). Each runner (5) has fixed thereto a cam follower (6) inserted in a groove (3) of the rotary platform (1) and coupled to a stationary closed-loop cam (4), and a retaining element (7) having a suction port (8) for retaining a container (M) and a suction outlet (9) in communication with the suction port (8). A stationary suction chamber (10) located above the rotary platform (1) has a perforated side wall (11) parallel to a portion of the closed-loop cam (4). Each suction outlet (9) moves in a path facing and adjacent to the perforated side wall (11) of the suction chamber (10) during a part of each rotation of the rotary platform.
