Device for transporting a hollow body comprising a magnetically actuated gripping means

Device (10) for transporting a hollow body (12) that is equipped with a neck (16) that comprises a vertically-oriented inner wall (24) and an upper edge (20) that circumferentially delimits an opening (22) for access to the inside of said hollow body (12), with said device (10) comprising at least means (60) for gripping the hollow body (12) by engagement with the inner wall (24) of the neck (16) that are mounted at the lower free end of a rod (34) and movably connected to the rod (34), with said rod (34) being mounted to move vertically between:

• A top position in which the gripping means (60) are retracted upward by the rod (34) to make it possible to insert the neck (16) of the hollow body (12) radially into a specified reference position in relation to the gripping means (60) of the device (10), and
• A bottom position in which the gripping means (60) engage radially with the inner wall (24) of the neck (16) to ensure the gripping of the hollow body (12),
• wherein the gripping means (60) are mounted to move radially
• between:
• A retracted position in which the gripping means (60) are inserted vertically from top to bottom inside the neck (16), without contact with the inner wall (24), and
• A deployed position in which the gripping means (60) engage with the inner wall (24) of the neck (16),
• and the change in position of the gripping means (60) from at least one to the other of said retracted and deployed positions is actuated by a magnetic field produced by magnetic means.
