Patent ID: 8276838

Claim:
A general winding and feeding apparatus, comprising: a base, a standing wall disposed on an upper side thereof, and a bottom plate disposed on a bottom thereof; a rotating shaft disposed on an upper side of said standing wall of said base, and used for engaging with a spool; a digital variable frequency motor installed in said standing wall of said base and connected with said rotating shaft, thereby providing rotating power to the shaft; a swing arm, one end thereof having a fixed shaft disposed on said standing wall, a positioning hole plate disposed on said fixed shaft, another end thereof having a rod thereby allowing the swing arm to be extend across a traveling material, a grating wheel installed in said rod; and at least two light-coupled sensors, a first light-coupled sensor installed in said swing arm at a position corresponding to said grating wheel of said rod of said swing arm to detect a rotational speed of said rod, a second light-coupled sensor thereof installed in said standing wall of said base at a position corresponding to said positing hole plate of said fixed shaft of said swing arm to detect a swing position of said swing arm and generating feedback to modify said motor rotating speed so as to permit traveling of said material to be maintained at a constant speed while said material is wound or fed.
