Abstract
A capping head assembly has a first housing with a spindle mounting collar and supports a clutch housing. The clutch housing has an upper portion with a first magnetic ring and a lower portion with a second magnetic ring. The lower portion is freely rotatable relative to the upper portion and permits the adjustment of the air gap between the first and second magnetic rings. A locking mechanism maintains the adjusted air gap at a selected value that represents a definable torque level in the magnetic clutch. The capping head also includes a post assembly calibration system that establishes a known reference point, which compensates for manufacturing tolerances between individual capping heads.
Claims31
A capping head assembly comprising a first housing having a spindle mounting collar means and means for supporting a clutch housing, said clutch housing having an upper portion with a first magnetic ring means and a lower portion with a second magnetic ring means, wherein said first housing means includes spline means and said clutch housing upper portion includes spline means adapted to cooperate with said first housing spline means for the axial displacement of said clutch housing relative to said first housing, and wherein said lower portion is freely rotatable relative to said upper portion, said lower portion including means for establishing an adjustable air gap between said first and second magnetic ring means, and locking means for maintaining said means for adjusting an air gap at a selected value.
A capping head assembly comprising a first housing having a spindle mounting collar means and means for supporting a clutch housing, said clutch housing having an upper portion with a first magnetic ring means and a lower portion with a second magnetic ring means, wherein said lower portion has a first member mounted for rotation in a fixed axial position relative to the clutch housing upper portion;
- a second member axially displaceable relative to said first member, said second magnetic ring means being mounted in said second member, whereby the axial displacement of said second member establishes an adjustable air gap between said first and second magnetic ring means, and locking means for maintaining said second member in a predetermined position relative to said first member.
An capping head assembly with an adjustable magnetic clutch comprising a clutch housing upper portion with a first magnetic ring means and a lower portion with a second magnetic ring means, wherein said lower portion is freely rotatable relative to said upper portion, said lower portion including means for establishing an adjustable air gap between said first and second magnetic ring means comprising a first member mounted for rotation in a fixed axial position relative to the clutch housing upper portion;
- a second member axially displaceable relative to said first member, said second member including means for supporting said second magnetic ring means so that rotatable movement of the second member about the first member adjusts the air gap between said first and second magnetic ring means and wherein one of said upper portion and lower portions includes means for axially displacing said first or second respective magnetic ring means relative to its respective upper or lower portion in order to calibrate the adjustable air gap between said first and second magnetic ring means independent of the rotatable movement of the second member about the first member.
