Abstract
A paper roll driving apparatus for use in a paper roll feeding apparatus comprises a prime mover moving mechanism being freely reciprocally movable along a guide rail and having a moving body on which a prime mover is mounted, and a driving transmission mechanism comprising a relay shaft provided on the moving body so as to be in parallel to the rotating shaft and rotatable, an arm mounted on the moving body so as to be pivotable around the axial center of the relay shaft and driven by the prime mover at least via the relay shaft, and a driving transmission mechanism having a pivoting means for pivoting the arm at a predetermined angle; wherein both the prime mover and the driving transmission mechanism being adapted so as to be integrally movable with respect to the paper roll support in parallel with the rotating shaft.
Claims4
A roll driving apparatus comprising:
- a frame;
- a roll shaft rotatably mounted on said frame and including a roll support axially movable on said roll shaft, said roll support having a plurality of aims rotatably supportable of a plurality of rolls, said roll support being rotatable with said roll shaft to move the rolls into different positions;
- a guide rail mounted on said frame and arranged substantially parallel to said roll shaft;
- a drive mechanism movably mounted on said guide rail and selectively connectable to said arms of said roll support to rotate a roll held by a respective said arm about an axial axis of the respective roll;
- a connecting body axially fixing said drive mechanism and said roll support together to cause said drive mechanism and said roll support to axially move together along said guide rail and said roll shaft.
