Abstract
A torque head assembly and method of capping effective to cap a variety of trigger spray cap bases or common caps to a spray bottle or container includes a drive roller mounted on a drive gear. The drive gear is in meshed gear communication with a plurality of train gears enclosed within a generally C-shaped driver housing wherein the a distal train gear engages a driven gear upon which a driven roller is mounted. An actuator allows the driver housing of torque head assembly to approach a variety of trigger spray cap bases or common caps within a plane generally horizontal thereto and at least partially co-planar therewith so as to capture the same between the dive roller and the driven roller and to thread mount the same onto the spray bottle or container.
Claims16
A torque head assembly for capping of a cap base to a container comprising:
- a drive mount and a driver housing,
- said drive mount having a pivot point serving as a fulcrum for said driver housing and a drive shaft responsive to a drive mechanism,
- said drive shaft being operative to rotate a drive roller and a drive gear, said drive gear being adapted to power a plurality of train gears within said driver housing, said train gears being operative to rotate a driven roller and a driven gear,
- wherein said plurality of train gears includes a first proximal train gear, a second intermediary train gear, and a third distal train gear each aligned in a common horizontal plane and said first proximal train gear is stationary and centered about said pivot point, and
- an actuator operable to cause an approach of said driver housing to said cap base in a generally horizontal plane at least partially co-planar with said cap base and to allow the drive roller and driven roller to contact an outer periphery of said cap base and rotate said cap base into threaded engagement with said container.
A method of capping a cap base to a container comprising:
- providing a container and a cap base unconnected to said container in proximity to a torque head assembly having a drive mount and a driver housing, said drive mount having a pivot point serving as a fulcrum for said driver housing and a drive shaft responsive to a drive mechanism, said drive shaft being operative to rotate a drive roller and a drive gear, said drive gear being adapted to power a plurality of train gears within said driver housing, and said train gears being operative to rotate a driven roller and a driven gear, wherein said plurality of train gears includes a first proximal train gear, a second intermediary train gear, and a third distal train gear each aligned in a common horizontal plane and said first proximal train gear is stationary and centered about said pivot point, and an actuator operable to cause an approach of said driver housing to said cap base in a generally horizontal plane at least partially co-planar with said cap base,
- actuating said actuator to cause said approach,
- contacting an outer periphery of said cap base with said drive roller and driven roller, and
- rotating said cap base into threaded engagement with said container.
