Abstract
A device for applying and removing threaded caps to and from threaded filler necks of containers includes a centering device, a rotatable grasping member mounted within the centering device for grasping a cap and turning the cap to thread it relative to the filler neck, a driver within the centering device for rotating the grasping member, and a resilient arrangement in a frame to resiliently hold the centering device relative to the frame and permit the centering device to move axially and radially relative to the frame. The frame and the centering device have sufficient clearance between them to permit axial and radial movement of the entering device relative to frame.
Claims15
A device for screwing and unscrewing caps into and from an internal thread of a filler neck attached to a cover plate and having a rim with an external rim bead comprising:
- a centering and screwing head having an outer centering member for mounting around onto the filler neck;
- a rotatable and axially movable wrench within the interior of the head for engaging a screw cap;
- drive means for driving the wrench;
- a supporting frame forming a compartment and having openings;
- and
- a resilient component in said compartment;
- between said head and said supporting frame for holding said head relative said frame;
- said centering and screwing head having a longitudinal axis;
- the centering and screwing head and said drive means being arranged within the compartment of said supporting frame with sufficient clearance to move laterally relative to said frame and being held relative to said frame by said resilient component to allow said head and said drive means to travel laterally and axially relative to said frame.
A device for applying and removing threaded caps to and from threaded filler necks of containers, comprising:
- a centering device having a longitudinal axis and a conical centering member for fitting over a neck;
- a rotatable grasping member mounted within the centering device for grasping a cap and turning the cap to thread it relative to the filler neck;
- a driver within the centering device for rotating the grasping member;
- a frame surrounding the centering device;
- and
- resilient means in the frame for resiliently holding the centering device relative to said frame and permitting the centering device to move axially and radially relative to said frame;
- and
- said frame and said centering device having sufficent clearance between them to permit the axial and radial movement of said centering device relative to said frame.
