Abstract:
A device for treating preforms to obtain containers made of plastics, comprising:an ejector suitable to pick up and release one or more of said preforms, arranged so that the neck of said preforms is directed upwardly, from a heating conveyor and a unit for transferring said one or more preforms unloaded from said heating conveyor, which is suitable to modify spacing and speed of said preforms, adapting them to spacing and speed of an adjacent and axially offset blow-molding conveyor to which said one or more preforms are transferred, wherein said ejector is composed of a first actuator, which allows to impart an upward motion by way of the movement of two jaws, to a selected series of supports, said upward movement of each series of supports being followed by a release of the corresponding preforms from said pick-up plugs, with consequent fall with the neck of the preforms facing upward at at least one present series of underlying series of cups, and wherein said series of cups is mounted on a carriage which can be moved along an axis X, said movement being obtained by means of a suitable first motor and being suitable to synchronize said carriage with said overlying series of supports so as to allow said preforms released by said ejector to fall into said cups after a first upward motion along an axis Z of said carriage.
