System for aiding in the replacement of a mould of a moulding unit of a machine for manufacturing containers

A system (10) for aiding in the replacement of a mold intended to be used for the replacement of at least one mold (18) of a molding unit (12) equipping a machine (14) for manufacturing containers by the forming, by means of at least one fluid under pressure, of a preform made from a plastic material having been thermally conditioned beforehand,

• said molding unit (12) comprising at least:
• two mold carriers (20) which are mounted so as to be movable between at least one open position and one closed position of the unit (20), and
• a mold (18) comprising at least two molding elements (22) capable of being brought together in order to occupy a joined position, or of being separated in order to occupy a disjoined position,
• inside which molding unit (12), each of the said at least two molding elements (22) of the mold (18) being adapted to be secured in a detachable manner to one of the associated mold carriers (20) by associated securing means (60), the said associated securing means (60) being adapted to be controlled when the molding unit (12) is in the closed position between at least one securing position and one release position,
• characterized in that the said system (10) for aiding comprises at least one device (16) for transporting a mold (18) forming a transportable unit subassembly, known as a joined mold, the said transport device (16) comprising at least one robotic arm (96) for positioning, in space, with respect to the molding unit (12) and along a trihedron (X, Y, Z), means (76) for handling at least one joined mold (18) so as to carry out a replacement of the said at least one mold (18) of the said molding unit (12).
