Patent ID: 8469179

Claim:
A machine ( 1 ) for treating containers, in particular in a plant for bottling food products, which comprises: a support frame; a turntable ( 70 ) rotatably mounted on said support frame to rotate around its own vertical shaft ( 74 ); a plurality of holding devices ( 2 ) for containers ( 8 ) mounted peripherally on said turntable ( 70 ) and each comprising: a support structure ( 4 ) mechanically connected to said turntable ( 70 ); at least one pincer equipped with two arms ( 15 ), each having a longitudinal development and pivoted on said support structure ( 4 ) to rotate around its own first rotation axis (Y); each of said arms ( 15 ) comprising at least one holding body ( 20 ) intended to grasp said container ( 8 ); an actuator ( 18 ) mechanically connected to said arms ( 15 ) to actuate these to rotate around said first rotation axis (Y) between at least one open position, wherein said holding bodies ( 20 ) are separated from one another to receive or release said container ( 8 ), and at least one closed position, wherein said holding bodies ( 20 ) are close to one another to hold said container ( 8 ) between them; wherein each of said holding bodies ( 20 ) of said holding device ( 2 ) are connected to a support body ( 15 ′) of the respective arm ( 15 ) through at least one articulation ( 21 ) suitable for allowing said holding body ( 20 ) to rotate at least around a second rotation axis (Z) lying on a plane (π) substantially perpendicular to said first rotation axis (Y) of said arms ( 15 ) and passing through them, wherein the second rotation axis (Z) of said holding body ( 20 ) being substantially parallel to the longitudinal development of said arm ( 15 ), in order to allow said holding body ( 20 ) to rotate around said second rotation axis (Z) adapting to the conicity of a neck ( 37 ) of different formats of containers ( 8 ).
