Abstract:
1. A rotary device for transferring containers, having a rotary base which rotates continuously about an axis of rotation and which supports at least one mobile assembly comprising: a main arm mounted pivotably on said base by means of a pivot shaft, the pivot shaft and the free end of the main arm defining a line which extends approximately tangentially to the circular trajectory of said pivot shaft, the pivot shaft preceding the free end of the arm in the direction of rotation of the base, a gripping pincer mounted on the free end of said main arm, and at least one freely rotating roller connected solidly to said main arm and capable of interacting with, by following, a fixed curvilinear cam extending along a closed contour, the curvilinear cam being configured in such a way that, during the rotation of the base the gripping pincer mounted on said free end of the main arm follows, over a fixed angular range of the rotation of the base, a predetermined circular path whose convexity is the inverse of the trajectory of the rotary base, wherein said gripping pincer is mounted at the free end of said main arm in such a way that it extends approximately transversely to the latter, and wherein, during the rotation of the base, the gripping pincer, mounted on the free end of said main arm driven by the follower roller which interacts with the cam, is moved by pivoting approximately radially.
