Contact stripper/feed wheel implementation
An embodiment includes an apparatus in an ATM to transport a document. The apparatus includes a feed wheel, a stripping tire, a clutch outer-hub and a clutch inner-hub. The feed wheel may be rotated by a first-rotational driver to move the document in a forward direction while the stripping tire is rotated by movable contact with the feed wheel. The clutch inner-hub prevents the stripping tire from rotating in a direction to cause the document to move in a reverse direction when the first-rotational driver rotates the feed wheel. Alternatively, the stripping tire is rotated by a second-rotational driver to move the document in the reverse direction when the feed wheel is not rotated by a first-rotational driver while the clutch outer-hub prevents the stripping tire from rotating in a direction to cause the document to move in the forward direction.
1. An apparatus of an automated transaction machine (ATM) to transport a document comprising:
a feed wheel adapted to be rotated in a first rotational direction by a first-rotational driver so that the feed wheel moves the document in a forward rectilinear direction;
a feed wheel shaft extending through the feed wheel and defining an axis of rotation of the feed wheel;
a stripping tire adapted to be rotated by the feed wheel to drive the document in the forward rectilinear direction when the first-rotational driver rotates the feed wheel in the first rotational direction, the stripping tire rotated by the feed wheel in a second rotational direction that is opposite to the first rotational direction;
a stripping shaft extending through the stripping tire and defining an axis of rotation of the stripping tire, the axis of rotation of the stripping tire and the axis of rotation of the feed wheel parallel to one another;
a first one-way clutch adapted to transmit rotation of the stripping shaft only when the stripping shaft is rotating in the first rotational direction;
wherein the stripping shaft is adapted to be rotated to move the document in a reverse rectilinear direction that is opposite of the forward rectilinear direction when the feed wheel is not rotated by the first-rotational driver; and
a drag clutch between the first one-way clutch and the stripping tire and adapted to urge the stripping tire to rotate in the first rotational direction to drive the document to move in the reverse rectilinear direction when the stripping shaft rotates in the first rotational direction.
2. The apparatus of the ATM of claim 1 , wherein, when the document is being moved by the feed wheel and stripping tire, the feed wheel and stripping tire are adjacent each other with the document between the feed wheel and the stripping tire, and wherein the feed wheel and stripping tire are touching each other when the document is not being moved by the feed wheel and the stripping tire.
3. The apparatus of the ATM of claim 1 , wherein first-rotational driver further comprises a first motor.
4. The apparatus of the ATM of claim 3 , wherein the first motor is a stepper motor.
5. The apparatus of the ATM of claim 1 , wherein the stripping tire is adapted to be rotated by the feed wheel through a document between the stripping tire and the feed wheel when the first-rotational driver rotates the feed wheel.
6. The apparatus of the ATM of claim 1 , further comprising:
a second one-way clutch interconnected with a portion of the drag clutch and adapted to prevent rotation of the portion of the drag clutch only in the second rotational direction.
7. The apparatus of the ATM of claim 1 , wherein the stripping tire rotates the feed wheel when the stripping shaft rotates.
8. The apparatus of the ATM of claim 1 , further comprising:
paddles attached to the stripping shaft and adapted to knock an end of the document downward when the document is being moved in the reverse rectilinear direction.
9. The apparatus of the ATM of claim 1 , further comprising:
a gear attached to the stripping shaft, and wherein the second-rotational driver is adapted to drive the stripping tire and the stripping shaft through the gear.
10. The apparatus of the ATM of claim 1 , further comprising:
a lower platen adapted to move a stack of documents so that the document in the stack of documents is aligned with a position between the feed wheel and the stripping tire.
11. The apparatus of the ATM of claim 1 further comprising:
paddles mounted on the stripping shaft and adapted to knock the documents in a downward direction when the stripping shaft is rotated in the first rotational direction, wherein the paddles further comprise:
arms adapted to extend outward from a center of rotation of the stripping shaft when the stripping shaft is rotated in the clockwise-rotational direction and, wherein the arms are adapted to contract inward toward the center of rotation when the stripping shaft is rotated in the second rotational direction.
