Abstract
Apparatuses include, among other components, a pair of opposing drive rollers, a pair of opposing idle rollers, and a rotatable support operatively connected to the axles of the idle rollers. Axles of the drive rollers and the idle rollers are positioned along a circle. The axles of the drive rollers and the idle rollers alternate along the circle. Also, rotation of the rotatable support moves the idle rollers along the circle until the idle rollers contact the drive rollers. Each of the idle rollers is positioned by the rotatable support to only contact a single drive roller at a time.
Claims17
An apparatus comprising:
- a pair of opposing drive rollers;
- a pair of opposing idle rollers, wherein axles of the drive rollers and the idle rollers are positioned along a circle, wherein the axles of the drive rollers and the idle rollers alternate along the circle;
- and
- a rotatable support operatively connected to the axles of the idle rollers,
- wherein rotation of the rotatable support moves the idle rollers along the circle until the idle rollers contact the drive rollers,
- wherein rotation of the rotatable support in a first direction relative to a frame of the apparatus causes a first idle roller to contact a first drive roller and a second idle roller to contact a second drive roller,
- wherein rotation of the rotatable support in a second direction opposite the first direction causes the first idle roller to contact the second drive roller and the second idle roller to contact the first drive roller, and
- wherein each of the idle rollers is positioned by the rotatable support to only contact a single drive roller at a time.
An apparatus comprising:
- a frame;
- drive rollers operatively connected to the frame;
- a rotatable support operatively connected to the frame;
- and
- idle rollers operatively connected to the rotatable support,
- wherein the drive rollers and the idle rollers lie in the same plane,
- wherein a pivot axis of the rotatable support is centered between axles of the drive rollers and centered between axles of the idle rollers,
- wherein the axles of the drive rollers are in a fixed position relative to the frame and the axles of the idle rollers move relative to the drive rollers as the rotatable support rotates,
- wherein rotation of the rotatable support in a first direction relative to the frame causes a first idle roller to contact a first drive roller and a second idle roller to contact a second drive roller, and
- wherein rotation of the rotatable support in a second direction opposite the first direction causes the first idle roller to contact the second drive roller and the second idle roller to contact the first drive roller.
A sheet transport device comprising:
- a frame;
- sheet transport paths operatively connected to the frame;
- and
- a path intersection nip driver positioned at an intersection of two of the sheet transport paths, wherein the path intersection nip driver comprises:
- drive rollers operatively connected to the frame;
- a rotatable support operatively connected to the frame;
- and
- idle rollers operatively connected to the rotatable support,
- wherein the drive rollers and the idle rollers lie in the same plane,
- wherein a pivot axis of the rotatable support is centered between axles of the drive rollers and centered between axles of the idle rollers,
- wherein the axles of the drive rollers are in a fixed position relative to the frame and the axles of the idle rollers move relative to the drive rollers as the rotatable support rotates,
- wherein rotation of the rotatable support in a first direction relative to the frame causes a first idle roller to contact a first drive roller and a second idle roller to contact a second drive roller, and
- wherein rotation of the rotatable support in a second direction opposite the first direction causes the first idle roller to contact the second drive roller and the second idle roller to contact the first drive roller.
