Abstract
An improved media rotator/translator apparatus includes a cylinder on sphere nip. A series of beveled/spur gears are included, one of which rotates co-axially but independent to the drive roll shafts. This enables the drive rolls to be driven about their own axis while simultaneously allowing for rotation about the roll shaft axis. A ball idler is positioned above each drive roll providing media normal force. Thus, sheet translation, jogging, and rotation is obtained, but with no relative motion, thereby eliminating marking of certain media.
Claims13
A finisher transport module includes an improved rotator and translator mechanism for use in controlling the orientation and alignment of media passing through said finisher transport module, comprising:
- a pair of cylindrical drive rolls over which said media passes, and wherein each of said drive rolls is in contact with and driven by intermediate rolls, and wherein each of said intermediate rolls is connected to a first beveled gear;
- shafts for supporting each of said drive rolls;
- spherical idler rolls forming nips with each of said cylindrical drive rolls;
- and
- an arrangement connected to said shafts for rotating said cylindrical drive rolls in horizontal and vertical planes.
A method for controlling the orientation and alignment of media passing through a finisher transport module, comprising:
- providing a pair of shaft mounted cylindrical drive rolls over which said media passes and wherein each of said drive rolls is in contact with and driven by an intermediate roll, and wherein each of said intermediate rolls is connected to first beveled gears;
- providing spherical idler rolls forming nips with said drive rolls;
- and
- providing an arrangement connected to said shafts for rotating said cylindrical drive rolls in horizontal and vertical planes.
