Automatic machine for manufacturing, checking, filling and capping bottles made of thermoplastic material

A machine for manufacturing, checking, filling with a liquid product and capping with caps, containers of thermoplastic material, said machine comprising:

• at least one extruder group adapted to produce several parisons arranged alongside each other;
• a mould group and counter-mould group having several adjacent cavities, said mould group and counter-mould group mounted on self centering horizontal-movement slides located on a translatable carriage which is adapted to be transferred alternately by suitable driving means from a position where said cavities are centered with respect to said parisons and then closed so as to grip a section of said parisons of predetermined length, to a first processing station, said first processing station comprising a blowing station adapted to perform blowing of a gripped parison, thereby forming the containers;
• pitching means for lifting and lowering of said at least one extruder group;
• further processing stations for the containers, aligned with one another and with respect to said blowing station, said processing stations comprising a second processing station for sprue removal and calibration of a mouth of the containers, a third processing station for checking compression and sealing strength of the containers, a fourth processing station for the filling of the containers, and a fifth processing station for capping of the containers;
• gripper groups adapted to perform a self centering closing and opening movement, and to synchronously grip a group of containers produced in the blowing station and to transfer said group to said further processing stations and then to an outlet;
• a waste conveyor arranged underneath said processing stations adapted to collect and remove production waste produced in said processing stations;
• and
• a programmable electronic control unit for governing operation of the machine.
