Abstract
Method and device ( 1 ) for separating parts ( 2 ), for example rotationally symmetrical closures, containers and/or preforms, the device comprising a transport apparatus ( 10 ) by means of which the parts ( 2 ) to be conveyed are able to be conveyed to, through or out of the device ( 1 ) along a transport path ( 16 ) in a transport direction ( 11 ), the transport apparatus ( 10 ) having at least one transport means ( 12 ) for transporting the parts ( 2 ) in one row and an accumulation section ( 13 ); and a blocking assembly ( 20 ) comprising at least one blocking element ( 20.1 ; 20.2 ) which is in the form of a rocker and the length of which extends in the transport direction ( 11 ), which blocking element defines a range of action W for the parts ( 2 ). The device ( 1 ) further comprises an actuator ( 30 ). The actuator ( 30 ) is designed to pivot the at least one blocking element ( 20.1 ; 20.2 ) into a first position in which a part ( 2.1 ) advancing into the range of action W is held back, and to pivot said at least one blocking element from the first position into a second position in which the advancing part ( 2.1 ) is able to be received within the range of action W.
