Abstract
A general winding and feeding apparatus includes a rotating shaft on the upper side of a standing wall of a base, and a motor is connected to the rotating shaft in the standing wall. A swing arm extends across a traveling material and is situated at a suitable position on the standing wall. Digital variable frequency methods may be used to drive the motor, which operates in conjunction with light-coupled sensors to detect the traveling speed of a material on the swing arm and sense a swing position of the swing arm. Feedback is generated in real-time to modify the speed of the motor, and the constant speed travel of the material can be achieved while being either wound or unwound.
Claims16
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.
