Abstract
A device (30) for serial treatment of hollow bodies including: a transport member (32); a treatment rod (38) mounted slidably relative to the transport member (32); controlled elements for moving each treatment rod (38) between a retracted position and an extended position in which the treatment rod (38) is intended for being inserted axially into the transported hollow body; wherein the controlled elements consist of an electric actuator (42) controlled by an electronic control unit (44) for stopping the treatment rod (38) in the extended position thereof. A method for serial treatment of preforms using the treatment device is also described.
Claims11
Device (30) for serial treatment of hollow bodies made of thermoplastic material, in particular preforms (12) made of thermoplastic material, comprising:
- at least one individual transport element (32) of a hollow body;
- at least one treatment rod (38) that is associated with said transport element (32), with the treatment rod (38) being mounted to slide axially in relation to the transport element (32);
- controlled means for moving each treatment rod (38) between a retracted position in which the treatment rod (38) is retracted above the hollow body transported by the transport element (32), and an extended position in which the treatment rod (38) is designed to be inserted axially into the hollow body transported by passing through a neck (16) of said hollow body;
- wherein the controlled means comprise an electric actuator (42), with the controlled interruption of the operation of the electric actuator (42) being controlled individually by an electronic control unit (44) for stopping the associated treatment rod (38) in its extended position.
