Patent ID: 7337893

Claim:
System ( 20 ) of feeding preforms, particularly designed to feed machines for blow moulding receptacles such as bottles, comprising, from upstream to downstream in the longitudinal direction of travel of the preforms ( 10 ), at least one sorting and alignment device ( 28 ) whose top end is provided with preforms ( 10 ) in a jumble and whose bottom end comprises at least two alignment rollers ( 38 ), substantially parallel and rotated about their respective axis (A 1 , A 2 ), that are designed to position the preforms ( 10 ) in feeding rails ( 30 ), inclined relative to the horizontal, to convey them to a machine ( 22 ), and comprising at least one ejection wheel ( 40 ) that is arranged above the preforms ( 10 ) and rotated about an axis (A 3 ), which axis (A 3 ) extends generally parallel to a plane of the feeding rails, characterized in that the ejection wheel ( 40 ) is arranged downstream of the alignment rollers ( 38 ) so as to eject incorrectly positioned preforms ( 10 ) from the feeding rails ( 30 ) and in that it comprises means ( 46 ) of lifting the incorrectly positioned preforms ( 10 ), including single preforms ( 10 C), of the lying type that extend in particular generally transversely relative to the feeding rails ( 30 ), so as to cause them to be ejected by the ejection wheel ( 40 ) arranged downstream.
