Single continuous belt in an escrow subassembly
An escrow unit has an escrow wheel and a movable-continuous belt. The escrow wheel rotates about an axis. The movable-continuous belt is wrapped partially around the escrow wheel forming an open gap between the belt and escrow wheel. The open gap allows the belt to transport a document through the open gap and to store the document by holding the document between the belt and the escrow wheel.
1. An apparatus comprising:
an escrow wheel configured to rotate about an axis;
a plurality of belt wheels mounted around the escrow wheel;
a pair of generally C-shaped plates rigidly attached to a housing and having at least three of the belt wheels mounted between the C-shaped plates and the escrow wheel; and
a movable-continuous belt wrapped partially around the escrow wheel forming an open gap between the belt and escrow wheel, wherein the open gap is configured to allow the belt to transport a document through the open gap and to store the document by holding the document between the belt and the escrow wheel.
2. The apparatus of claim 1 wherein when the belt is in motion some of the belt is moving clockwise around the escrow wheel and some of the belt is moving counterclockwise around the escrow wheel.
3. The apparatus of claim 1 wherein between 60 percent and 99 percent of an outside circumference of the escrow wheel is wrapped by the belt with the belt touching the escrow wheel when the apparatus is not holding the document.
4. The apparatus of claim 1 wherein between 60 percent and 95 percent of an outside circumference of the escrow wheel is in contract with the belt when the apparatus is not holding the document.
5. The apparatus of claim 1 wherein between 70 percent and 90 percent of an outside circumference of the escrow wheel is in contact with the belt when the apparatus is not holding the document, and wherein between 70 percent and 90 percent of an outside circumference of the escrow wheel is covered by a portion the belt that is not in contact with the escrow wheel when the apparatus is not holding the document.
6. The apparatus of claim 1 wherein the movable-continuous belt rotates the plurality of belt wheels rotate in a same direction and causes the escrow wheel to rotate in a direction opposite to the plurality of belt wheels.
7. The apparatus of claim 6 further comprising:
a housing;
an upper-receiving plate rigidly mounted to the housing;
a document-guide plate, wherein the document-guide plate, the upper-receiving plate, at least one of the plurality of belt wheels and the belt are configured to transport the document between the upper-receiving plate and the document-guide plate and then onto the escrow wheel.
8. The apparatus of claim 7 further comprising:
a swing arm, wherein one of the plurality of belt wheels is a first swing arm belt wheel, wherein one of the plurality of belt wheels is second swing-arm belt wheel, wherein the swing arm rotates about an axis of the first swing-arm belt wheel, and wherein the swing arm and the document-guide plate rotate about an axis of the second swing-arm belt wheel.
9. The apparatus of claim 8 wherein the housing further comprises:
slots configured to receive projections of the document-guide plate to guide movement of the document-guide plate.
10. The apparatus of claim 8 wherein the document-guide plate further comprises:
a pair of elongated-vertical flanges, wherein a portion of the belt travels between the pair of elongated-vertical flanges pushing the document downward between the pair of elongated-vertical flanges.
11. The apparatus of claim 8 wherein the second elongated-vertical flange is biased toward the escrow wheel.
12. The apparatus of claim 9 further comprising:
elongated paddles configured to rotate about the axis of the second swing-arm belt wheel and to knock an edge of the document upward and onto the document-guide plate when removing the document from the escrow wheel.
13. The apparatus of claim 1 wherein the belt travels at least partially between the C-shaped plates.
14. The apparatus of claim 1 wherein the escrow wheel is configured to accept a plurality of documents between the belt and the escrow wheel, and wherein the belt is a polymer.
15. An Automated Transaction Machine (ATM) apparatus comprising:
a center and de-skew (CDS) subassembly;
an escrow wheel having a circumference and the escrow wheel rotates about an axis;
a continuous belt with a first portion of the belt wrapped around at least 75 percent of the circumference of the escrow wheel and biased toward the wheel, a second portion of the belt wrapped around at least 75 percent of the circumference around the escrow wheel and held apart from the escrow wheel, wherein the belt forms an open gap void of the belt allowing a document to travel through the open gap directly toward and onto the escrow wheel to become held by the escrow wheel between the belt and the escrow wheel, and wherein the first portion of the belt is between the escrow wheel and the second portion of the belt.
16. ATM of claim 15 further comprising:
a plurality of belt wheels configured to hold the second portion of the belt wrapped apart from the escrow wheel, wherein at least one of the belt wheels is biased toward the escrow wheel.
17. ATM of claim 15 wherein the document travels in a linear direction that is perpendicular to the axis when traveling through the open gap directly toward and onto the escrow wheel.
18. ATM of claim 15 wherein the document is removed from the escrow wheel and transported out the open gap by reversing direction of the belt to a direction opposite of a direction of when the document traveled through the open gap directly toward and onto the escrow wheel.
19. A method comprising:
moving a document along a travel path through a center and de-skew (CDS) subassembly such that the document is center-aligned along the document travel path;
passing a first portion of a continuous belt around at least 75 percent a circumference of an escrow wheel, wherein the first portion touches at least 75 percent of the circumference when the document is not being held by the escrow wheel;
passing a second portion of the continuous belt around the at least 75 percent of the circumference of the escrow wheel, wherein the second portion does not touch the escrow wheel; and
rotating the belt to move the document along the document travel path and perpendicular to a rotational axis of the escrow wheel through an open gap in the belt onto the escrow wheel so that the document is at least partially between the escrow wheel and the belt.
