Patent attributes
A filler device sub-assembly having a manipulator for manipulating a cap of a container comprising a first and second cap gripper arm and a member for controllably manipulating the cap gripper arms. The controllable manipulating member comprising an inner cam assembly, an outer cam assembly and a follower. The outer cam assembly extends at least partially about the inner cam assembly. One of the inner and outer cam assemblies coupled to the first and second cap gripper arms. The follower is associated with the inner cam assembly and the outer cam assembly. Movement of the lifter shaft imparts movement of the follower and relative movement of the inner cam assembly and the outer cam assembly, to in turn, longitudinally and rotatably move the cap gripper arms from a first position proximate to a container to a second position distally spaced from a container.
