1. Assembly machine (1) adapted to assemble caps (3) onto spouts (2), the assembly machine comprising:
a spout supply (10) adapted to supply spouts (2) in succession at a spout supply position (A); a cap supply (20) adapted to supply caps (3) in succession at a cap supply position (B); a frame comprising:
a cap guide arc (30), mounted stationary in the frame, which cap guide arc is adapted to receive each cap (3) from the cap supply (20) and to guide the cap between the cap supply position (B) and a cap pick-up position (C);a turret assembly (40) which is rotatable about an essentially vertical rotation axis (R), which is provided along and adjacent to the spout supply position (A), the cap supply position (B) and the cap guide arc (30), the turret assembly passing, in the direction of rotation, the cap supply position (B), the cap pick-up position (C), an assembly position (D) in which cap and spout are assembled and an assembled cap-and-spout expelling position (E) wherein the assembled cap-and-spout is expelled from the turret assembly, the turret assembly (40) comprising:
a circular spout transporter (41), provided with spout receptacles (41a) each adapted to receive a spout from the spout supply (10) at the spout supply position (A), the spout transporter (41) being adapted to transport each spout at least between the spout supply position (A), via the assembly position (D), towards the expelling position (E),a cap positioning element (42) provided above the cap guide arc (30) in an operative position thereof, the stationary cap guide arc being provided above and parallel to and having the same radius as the spout transporter (41), the cap positioning element (42) being adapted to position the cap in, and guide the cap along the cap guide arc (30) in the operative position thereof between the cap supply position (B) and the cap pick-up position (C), the cap positioning element (42) being retractable to a non-operative retracted position when remote from the cap guide arc,a cap assembly unit (43) provided above the spout transporter (41), the rotation path of which being parallel to and having the same radius as the spout transporter (41), the cap assembly unit being adapted to pick up the cap at the pick-up position (C) and assemble the cap onto the spout at the assembly position (D), the cap assembly unit being movable up-and-down between a non-operative upper level, via a lower-situated pick-up level at the cap pick-up position (C) to a lowermost assembly level at the assembly position (D). |
