Patent ID: 8522956

Claim:
A singling apparatus ( 1 ) for cylindrical bodies ( 2 ), such as preforms for hollow bodies, which have at a first end at least one projection ( 5 ) and at a second end a diameter smaller than the diameter of the projection ( 5 ), wherein the singling apparatus ( 1 ) includes a pair of parallel oriented guidance elements ( 7 ) between which the cylindrical bodies ( 2 ) can be set up thereby that the cylindrical bodies ( 2 ) are each suspended by the projection ( 5 ) on the guidance elements ( 7 ) and the cylindrical bodies ( 2 ) form a single row ( 8 ) along the guidance elements ( 7 ) and are thus conductable to a run-off ( 9 ) for the further conveyance of the cylindrical bodies ( 2 ), wherein the singling apparatus ( 1 ) comprises a detection device, which detects incorrectly positioned and/or interlaced cylindrical bodies ( 2 ) and is equipped with a control device for ejection arrangements, as well as a first ejection arrangement ( 21 ) with an ejection means ( 26 ) extending between the guidance elements ( 7 ) for ejecting cylindrical bodies ( 2 ) and a second ejection arrangement with a blow-gun device( 31 ) for ejecting cylindrical bodies ( 2 ) by means of blowing them away from the guidance elements ( 7 ); wherein the ejection means ( 26 ) of the first ejection arrangement ( 24 ) is a moveable ejection means, which, for the purpose of ejecting an incorrectly oriented cylindrical body ( 2 ), moves from below between the guidance elements ( 7 ) and thus lifts this cylindrical body ( 2 ) and ejects it.
