Abstract
Abstract An improved bill transport and stacking mechanism is provided for currency handling machines and is adapted for efficient transport and stacking of curled currency bills, documents and the like. The bill transport path is provided with members for exerting transverse bending forces on opposed side edges of a bill immediately before the bill moves away from positive contact with the transport path surface. The transverse bending forces effectively "stiffen" the leading longitudinal bill edge so as to counteract any tendency the bill has to curl away from sustained contact with the transport path. The arrangement prevents curled bills from conforming to their original curled shape and forces such bills to be positively relayed from the bill transport path onto stacker blades positioned immediately downstream thereof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
193 words
In a document handling system for processing documents such as currency bills, the system including an input path for receiving currency bills to be processed along which bills may be moved along a first direction, an output path along which bills may be moved along a second direction, a curved guideway disposed between said input and output paths and for accepting bills from said input path and guiding them along said second direction onto said output path, and a pair of spacing wheels disposed downstream of the output path and spaced therefrom for receiving bills moving out of the output path and stacking them for subsequent removal, each of said stacking wheels having multiple flexible blades for capturing and holding successive bills from said output path, the improvement comprising means for exerting transverse bending forces on the leading opposite side edges of a processed bill before said bill moves away from contact with said output path and into engagement with said stacking wheels, said forces effectively stiffening the leading longitudinal edge of said bill so as to prevent said leading bill edge from moving away from said output path and said stacking wheels.
Claim 2
Dependent Claim
193 words
In a document handling system for processing documents such as currency bills, the system including an input path for receiving currency bills to be processed along which bills may be moved along a first direction, an output path along which bills may be moved along a second direction, a curved guideway disposed between said input and output paths and for accepting bills from said input path and guiding them along said second direction onto said output path, and a pair of spacing wheels disposed downstream of the output path and spaced therefrom for receiving bills moving out of the output path and stacking them for subsequent removal, each of said stacking wheels having multiple flexible blades for capturing and holding successive bills from said output path, the improvement comprising means for exerting transverse bending forces on the leading opposite side edges of a processed bill before said bill moves away from contact with said output path and into engagement with said stacking wheels, said forces effectively stiffening the leading longitudinal edge of said bill so as to prevent said leading bill edge from moving away from said output path and said stacking wheels.
Claim 3
Dependent Claim
110 words
The improved document handling system according to claim 1 wherein said output path includes a flat section along which said bills are moved under positive contact against said output path by at least one transport roller mounted for rotation about a corresponding support shaft, said side edges of said bills having sections extending transversely on either side of said transport roller, said transverse bending forces being exerted by a pair of blocks disposed at positions adapted to counteract said extending sections of said opposing side edges of said bill, said forces being applied in a direction generally perpendicular to the direction of movement of said bill along said output path.
Claim 4
Dependent Claim
69 words
The improved document handling system according to claim 2 wherein said processed bills are substantially curled and have a tendency to curl away from said flat portion of said output path, and said transverse forces are applied in such a way that said stiffening of said leading longitudinal bill edge forces said edge toward said output and prevents it from curling away from subsequent contact with said stacking wheels.
Claim 5
Dependent Claim
35 words
The improved document handling system according to claim 3 wherein, said transverse forces are applied to said opposing leading sides edges at positions substantially in line with the axis of rotation of said transport shaft.
Claim 6
Dependent Claim
29 words
The document handling system of claim 1 wherein the blades of each of said stacking wheels are annularly offset from the blades of the other of said stacking wheels.
