<p>A container gripper, in particular for bottles, which is positionable on a movable part (13) of a manipulating machine, and comprises a support structure (15, 18) internally carrying a pair of arms (16) driven to rotate between a closed rest position in which they face each other to retain the container, and an open position in which they are withdrawn from each other to release the container; in this gripper the support structure comprises a U-shaped bracket (15) supporting a block (18) rotatable about the bracket, the arms (16) being pivoted to the block (18) and carrying, pivoted to the opposite end to their gripping end, a pair of connecting rods (31) for rotating the arms, one of the connecting rods extending into a right-angled lever (33) which can engage a cam (14) fixed relative to the movable part (13) of the manipulating machine, the connecting rods (31) being pivoted at their other ends to a pin (37) slidable within a seat (39) in the block (18) by way of an interposed elastic element (41) which when at rest maintains the arms in their closed position. <IMAGE></p> |
