DISPOSITIF A LEVIERS POUR GUIDER UNE TULIPE DANS UNE MACHINE A REMPLIR DES RECIPIENTS

摘要

A machine for filling containers with liquids has a vessel which rotates about a vertical axis and carries an annulus of downwardly extending filling devices each of which guides a reciprocable centering and sealing member for a container which is held in register with the respective filling device during introduction of a liquid. The mechanism for moving the centering member toward and from sealing engagement with a container below the respective filling device employs a one-armed lever which is pivoted to the vessel and is articulately connected with the centering member, a link which is connected to an intermediate portion of the lever, a bell crank which is pivotably mounted on the vessel and has a first arm coupled to the link and a second arm provided with a follower, a stationary cam which is tracked by the follower, and a helical spring which reacts against the vessel and biases the follower against the cam. When the cam allows the spring to expand, the centering member descends into sealing and centering engagement with a container.
