DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a document transport device for transporting documents around corners. The invention also provides a method for transporting checks and other documents that may be crumpled and folded before being provided to a banking device.
l#2 'r'A as used in banking equipment
Regarding the mechanism. Further, the present invention relates to an apparatus capable of handling folded corners of a document in order to advance the folded corner of the document in a conventional 1-rack.

BACKGROUND OF THE INVENTION It is well known in banking to use check T-code devices to automatically process checks and related documents. The check encoding device is supplied with stacks of checks, and individual checks are transported through the device for reading data therefrom as well as for being stacked in appropriate ejected stacks. In order to minimize the size of such devices, it is necessary to use curves with one or more curves, rather than the otherwise ideal single straight curve. .

Checks and related documents are subjected to mechanical abuse by the public before being accepted into banking equipment.

This check may be bent. The folding of the document provides mechanical strength to the document that it does not otherwise have. Problems therefore exist when handling folded documents, especially when handling documents with folds present in the transport direction. Firstly,
Folded documents exhibit a more crowded effective cross-sectional area than would be expected of an unfolded document, and can jam on the sides of narrow openings that would otherwise receive the document. become. The folds in the document provide longitudinal strength to the document to resist forced entry into the aperture.

When the mechanical strength limitations of a folded document are overcome, the document can tear and collapse causing jams in the fittings transport device.

Conveyance of folded documents can take place in corners with very tight radii, where the conveyance of documents is
The frictional force of the folded document against the edge of the frame is insufficient to cause the document to stop folding or collapse. Due to the additional sizing required of the document processing device to accommodate large radius corners, it is not advantageous to provide a document processing device in which documents are conveyed around large diameter corners. Therefore, 'I
Q: A document that is bent in the direction that exists in the iM force direction is
It would be desirable to provide a document transport device that is capable of transporting around small diameter doors.

For purposes of this specification, a "corner fold" is defined as the portion of the leading edge of a document that is folded out of the plane of the document.

Mishandling of checks and banking documents often results in corner folds in the document, meaning that a corner of the document becomes a lip that is folded out of the plane of the document. Corner folds add to the width of the document and can block the introduction of the document into the carrier handling truck. Therefore, it would be desirable to provide an apparatus that can make documents with folded corners suitable for transport along the document rack.

Structure and Operation of the Invention The present invention is a document transport device for transporting documents around corners, said transport device guiding an edge of a document in a curved path around said corner. a curved track for urging the document along said path; a curved border adjacent to the track on the 1 side of the corner for supporting the w1
a brake cylinder spaced apart from the boundary across the inlet to the delivery device;
The cylinder and the boundary part reduce the core strength given to the document by cutting the surface of the document (1X1) due to bending in the direction of the path. to release the fold of the document existing in the direction of the path, and the driver releases the fold of the document so that it can be softened for completion of the conveyance around the chair. The device operates to bias the document against the curved border so that it is flattened against the curved border.

In a first preferred embodiment, a curved track is provided in which the groove receives the lower edge of the document. The curved boundary is placed adjacent to the track.
There is. In a first preferred embodiment, this curved boundary is a wall. This wall supports the document against tilting from the track as it curves. Preferably,
This wall forms one side of the groove and extends over the entire height of the document. A brake cylinder is provided on the side of the truck opposite the wall, spaced from this wall, and connected to the document transport device. The document enters the general feeder by passing between the brake cylinder and the wall. The brake cylinder cooperates with the wall to release all longitudinal folds of the document as it enters the transport device.

The document is forced by the driver into the conveyor and around the curve. The driver preferably consists of a driven fb wheel that presses against an idler pinch wheel.

The document is preferably gripped near the edge adjacent the vortex between the friction wheel and the idler wheel so that it can be forced around the track.

The driver pushes the unfolded document around the truck and against the walls. The document is flattened against the wall, thereby making it flexible for continued transport around corners.

The brake cylinder is rotated to advance the document around the track, and as the bend strikes the brake cylinder, the rotation of the brake cylinder forces the corner of the bend toward the wall, thereby propelling the document. prevent clogging.

Preferably, the brake cylinder rotates at a surface speed equal to the transport speed of the document around 1 to 1 rack. The brake cylinder is preferably mounted for rotation with the friction wheel, in which case the brake cylinder is preferably coaxially mounted for rotation on and on the FJIIY wheel.

The brake cylinder is inclined through a small predetermined angle in the transport direction of the document so that rotation of the brake cylinder tends to push the document forward within 11. The friction wheel and idler pinch wheel assembly are preferably similarly tilted to force the document through the one to one rack groove.

In the first example of the first preferred embodiment, the combination of the brake cylinder and the driven friction wheel is preferably (
1. Driven by motor means coaxially coupled in the vicinity of the track to a driven friction wheel.

In the second embodiment of the first preferred embodiment, the brake cylinder assembly is preferably driven by belt drive means rotating over the driven friction wheel.

Preferably, a lip is provided adjacent to the brake cylinder at the inlet of the conveying device, forming a known path between the wall and the brake cylinder in order to gently open the bend.

In a second preferred embodiment of the invention, the curved boundary, in the previous example the wall, is provided with a small number of J. Everything is the same as in the first preferred embodiment, except that : is replaced. In the first example of the second preferred embodiment, the guide cylinder is rotated by the passing document engaging the guide cylinder.
It is a cylinder. In a second example of the second preferred embodiment, the guide cylinder is dynamically rotated to assist the document around one to one rack. Where the belt cylinder is rotated by the belt drive mechanism, this belt drive mechanism is preferably adapted to drive the guide cylinder.

In a variant of the second example of the second preferred embodiment, the guide cylinder, like the plate cylinder, is tilted to force the document into the groove in the 1-rank.

Both the first and second preferred embodiments are corner foldable rlPs at the leading edge of the document.

A corner fold appears between the brake cylinder and the border at the entrance of the conveying device. If the edge of the corner fold is closer than a predetermined distance from the plane of the document, the corner fold will rest between the brake cylinder and the boundary and will therefore lie again in the plane of the document. If the edges of the corner fold are separated by more than a predetermined distance from the plane of the document, the boundary from the brake cylinder straightens the corner fold relative to the surface of the document. Fold it back. In both cases, the one-bit width that would impede the progress given to the document by corner folds is removed.

The invention will be further explained by way of example in the following description with reference to the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a projection view of a first preferred embodiment of the invention.

The curved track 10 is provided with a groove 12 in which a lower edge 14 of a document 16 is received. This groove 12 has a curved i
~Documents 16 around the corner formed by the rack 10
work to guide. The platform 18 bounds the groove 12 on the inside of the corner and the boundary wall 2
A curved border in the form of 0 forms the outer full 12 sides of the corner. Preferably, the boundary wall 20 itself forms the outer boundary of the groove 12. However, boundary wall 2
It is also possible that the groove 12 is spaced apart from and simply adjacent to the groove 12. The degree of radial separation between the outer boundary of tF+t 12 and the boundary wall 20 also
It will be clear from the description below that this can be done in any number of ways.

Document 16 may include one or more longitudinal folds 22. The longitudinal bend 22 is aligned with the first arrow 2 such that the bend 22 provides strength to the class m 16.
It does not have to be exactly in the direction of transport of the document 16 as indicated by 4.

It is only necessary that the bend 22 has a directional component in the conveying direction. Longitudinal bends 22 are undesirable and provide mechanical strength to document 16 to resist bending in both directions of transport and across the surface.

A driven friction wheel 28 engages the document 16 near the lower edge 14 of the document 16. The driven friction wheel is Bran 1
- rotatably mounted on the platform 18; Brake cylinder 30 is mounted coaxially on driven friction wheel 28. The brake cylinder 30 rotates with the friction wheel 28 and is fixed thereto. Both of these are installed near bluff 1 to platform 18 (
The brake cylinder 30 is driven by a coaxial direct drive motor 32 which is connected to the brake cylinder 30 and is driven by a direct drive shaft 34 through a penetration in the platform 18
and the driven friction wheel 28.

Brake cylinder 30 is 1 yen of bent document 16
The brake cylinder 30 is spaced from the boundary wall 20 by a distance sufficient to allow the path to fall between the brake cylinder 30 and the boundary wall 2°.

This boundary wall 20 is provided with an inlet lip 36 adjacent to the brake cylinder 30 .

The folded paper 16 is engaged by the scraping wheel 28, so that the folded document 16, together with the inlet lip 36, is pulled into the space between the brake cylinder 30 and the boundary wall 20. All sharp corners of the bend slide against the curved surface of the brake cylinder 30 and the sloping surface of the inlet lip 36, so that this bend is The width may be slightly wider than the clearance between. Furthermore, brake cylinder 3
A rotation of 0 operates to cause the brake cylinder 30 to offset all sharp folded edges and retract the fold in the direction of the space between the brake cylinder 30 and the boundary wall 20.36. .

The mating of inlet lip 36 and brake cylinder 30 is such that document 16
form a shortened path for. brake cylinder 30
The curvature of the cylindrical surface of the document 16 and the entrance lip and wall 20 etc. cooperate to constantly (ζ) reduce the concave width of the document 16, thereby increasing the fold 22 of the document 16.
Release.

By releasing the folds 22, the mechanical strength imparted to the document 16 that resists bending of the document in both directions transverse to its path and surface is reduced. The remaining small angle that is allowed is not sufficient for the document 16 to resist the elasticity due to jamming against the boundary wall 20.
The friction between the boundary wall 20 and the boundary wall 20 causes the document 16 to slide against all the remaining folds, causing the document 16 to be flat against the boundary wall 20.
The vortex 12 is made into a generally flexible material for continuous transport around the vortex 12.

Force for flattening the document 16 against the boundary wall 20 (1,
The brake cylinder 30 is provided by the friction wheel 28 and is partially provided by the brake cylinder 30 from the J die ref 1~ drive motor 32.
The motor 32 may be a brush commutated or brushless commutated motor whose speed is adjusted;
Or it may be a step motor.
~-Drive may be provided via a gearbox.

FIG. 2 is a view of the conveying device of FIG. 1 taken along line Δ-8 in the direction of the arrow in FIG. This direct
Drive motor 32 has been omitted for simplicity.

The friction wheel 28 is 1 to 1 on the opposite side of the stand 12.
The brake cylinder 30 rotates by engaging the idler pinch wheel 38 which is mounted on the platform 40 of the entry point 1 to the platform 40. It is parallel to the plane and parallel to the surface of the document 16 when the document 1G enters the transport mechanism.

The axis of the brake cylinder 30 is l-rack 10°1
It does not have to be exactly parallel to the wall 20 that enters the inlet of 2. Without departing from the operation of the invention as described above, the brake cylinder 30 applies a wider bend 2 to a portion of the document 16 than other portions of the flap 16.
It can be tilted to fit 2. Similarly, the idler pinch wheel 38 and the driven friction wheel 28 can be sized inversely, allowing the idler wheel 3
8 is alternatively driven by motor 32 to impart rotation to friction wheel 28 by mechanically coupling document 16 directly, 4j, and indirectly when document 16 is present. In either case, the rotation of the driven friction wheel 28 is the same as that of the friction wheel 28.

Give rotation to 0.

3. FIG. 1 shows the apparatus of FIG. 1 viewed along the line 11B--B- in the direction of the arrows. Again, the dielectric 1 to the drive motor 32 have been omitted for simplicity.

;! As the first rack 16 passes along the first rack 10, the rotation of the cylinder 30 is 1:5 in the groove 12.
Please refer to page 16 (page 16) for brake cylinder 3.
0Φ+b I! i! = 12 fL, which is an angle θ away from 00'' with respect to the transport direction of the document 16.

The axis of the machine wheel 28 is similarly inclined and also forces the document 16 within the groove 12. The idler wheel 38 is preferably tilted as well.
However, those skilled in the art will recognize that the idler wheel 38 may be placed in other planes.

The combination of friction wheel 28 and idler wheel 38 is used in a preferred embodiment of the invention merely to illustrate a preferred example. lfi 12
Other methods of transporting the documents 16 onto the inner trucks 10 may also be used. There may be one brake cylinder 30 (J independently rotating 1).

Preferably, the cylinder 30 rotates at a surface speed equal to the speed at which the document 1G is transported around the track 10. The preferred fruit l1iI shown here! In example i (1), this is achieved by making the diameter of the brake cylinder 30 the same as the friction wheel 28. The document 16 can be rotated and the document 16 can be pushed further into the track 10 d412. Similarly, there is a difference between the transport speed of the document 1G and the surface speed of the brake cylinder 30. When present, the brake cylinder 30 is always connected so that the class 16 slides without any obstruction to it.
It can be made from low friction materials.

The apparatus shown in Figures 1, 2 and 3 is 90°
provides transport of the document 16 through an angle of .

It should be understood that the document may be conveyed at angles greater or less than 90 degrees. moreover,
It should be appreciated that additional drivers may be included around the racks 10 to move the documents 16. This additional driver allows the document 16 to move faster within the truck 10 between the friction wheel 28 and the idler.
A special pair of friction drive wheels 28 and an idler wheel 38 are provided which are arranged to grip the document 16 before it passes completely from the other pair with the wheels 38.

FIG. 4 shows a variation on the preferred embodiment of FIG. 1 in which the transport mechanism can be mounted on a flat surface without any penetrating elements below the level of 1-rack 1o. Instead of the direct drive motor 32, a belt drive motor 44 is provided with a belt drive motor 44 that passes around the pulley 7I8 on the belt drive motor 44 and around the constriction 5o between the brake cylinder 30 and the friction wheel 28. 1-46 is provided for driving the brake cylinder 30 and friction wheel 28 combination V. This bell 1 drive motor 44 can be mounted substantially in the plane of the track 10 and a protrusion of the conveying device below the plane of the rack 10 is therefore unnecessary. Although the constriction 50 is shown in FIG. 4 with a large hole for clarity, it is actually a bend across the width of the brake cylinder 30t and the bend 22. In order to engage and remove the maximum number of sections 22, the length of brake cylinder 30 should be as small as possible to enclose. As an alternative configuration, the waist portion 50 is
It may also be made as a simple thrower 1- in the surface of the brake cylinder 3o.

FIG. 5 shows a second preferred embodiment of the invention. A wall 20 is located outside the bend of the shoulder 54 of the track 10.
This is similar to that shown in FIG. 1, except that it has been replaced by multiple rows of guide cylinders 52 located in the rack 10-t.

Guide cylinder 52 forms a path for document 16 identical to that formed by wall 20.

The first guide cylinder 52 in the track 10, by virtue of its curved surface, effectively performs the same action as it would if it were deflected by the wall 20 and entrance lip 3G shown in FIG. It should be appreciated that while the guide cylinder is shown to be of the same diameter as the brake cylinder 30, the guide cylinder 52 has a different diameter than the brake cylinder 30. be. moreover,
The guide cylinders 52 do not have to have the same diameter.

In a first example of the second preferred embodiment, guide cylinder 52 is an idler cylinder. A guide cylinder 52 is mounted for rotation about its axis on a shoulder 54 of the track 10. When the document 16 hits the guide cylinder 52, the guide cylinder 52 moves to ? ='+ jli rotated by friction of 16 and r smaller than would be given by wall 20 in FIG.
19 is applied to the path of the document 16. The guide cylinder has its axis parallel to the surface of the document 16 and the document 1
It is installed at right angles to the path of 6.

In a second variant of the second preferred embodiment, the guide cylinder 52 is driven. The guide cylinder 52 is Class M 16
is driven to rotate at a surface speed equal to the conveying speed of. Therefore, this document 16 has no friction against the guide cylinder 52. Each of the guide cylinders 52 is rotated 1q by an independent motor. Guide cylinder 52 (may be rotated by a common motor.

Similarly, both guide cylinder 52 and brake cylinder 30 may be rotated by the same motor.

In this second variant of the second preferred embodiment, the guide cylinder 52 is tilted in the direction of conveyance of the document 16, as is the play cylinder 30 for pushing the document 16 in the groove 12. The guide cylinder 52 can be operated in conjunction with the pair of friction wheels 28 and pinch wheels 38 in the same way that brake cylinders are operated.

A second preferred embodiment, shown in FIG. 5, is shown used in conjunction with a direct drive motor 32, but
The embodiment of FIG. 5 is shown in FIG.
It should be appreciated that 88M44, 48, 46.5 ol, = can be used equally and give the same space saving effect.

In the preferred embodiment described above, the angle of inclination θ of the axis of the brake cylinder is chosen to be within the range of 5° to 10°. This angle θ (i-rack 12, brake cylinder 30, boundary 20.52
, along with the combination of friction wheel 28 and idler wheel 38, can be chosen to have different values depending on the frictional nature of document 16.

FIG. 6Δ shows the document 16 with its corners folded. A row of numbers 53 to be read by the banking device is provided adjacent to the lower edge 14 of the document 16. nI
The class 16 is conveyed in the direction of the second arrow 54. Folded corner 56 is created at leading edge 57 of document 16 by folding from the plane of document 16 along fold line 58 , as shown by third arrow 60 .

FIG. 6B shows the result of passing the document 16 through the transport device of FIGS. 1-5, where the folded corners 5
The leading edge of 6 is sufficiently far from the plane of document 16 such that the leading edge is pushed back by brake cylinder 30.

Upon being pushed back, the folded corner 56 is folded back as shown by the fourth arrow 62 and flattened against the plane of the document 16.

1 to be read by the device (by means not shown)
Because the column numerals 53 are located close to the bottom edge 14 of the document 16, the folds of the corner folds 56 shown in FIG.
is made flexible and provides approximately the same cross-sectional area as if corner creases 56 were not present. Thereby, the document 16 is advanced to a conventional document handling device.

FIG. 6C shows the document 16 of FIG. 6 passing through the transport apparatus of FIGS. The brake cylinder 30 and the interface 20 .
52, sufficiently close to the plane of document 16 to be placed between document 16 and document 16. The rotation of the brake cylinder 30 is F
By catching the corner fold 56 by J rubbing, document 1 is
This has the effect of drawing out the corner fold 56 within the plane of 6.

In this case, the brake cylinder 3o is connected to i~crank 0
Preferably, the rotation is performed at a surface velocity that exceeds the linear velocity of the document 16 within the paper.

In FIGS. 68 and 6B, it is assumed that the corner fold 56 exists on the side of the document 16 on which the button cylinder 30 is placed, but the corner fold 56 on the other side of the document 16 is It should be noted that the border 20 is engaged and folded back towards the document 16. Boundary I! 1I20 consists of a series of driven guide cylinders 52 shown in FIG. The first guide cylinder 52 encountered by the document 16 has a linear velocity greater than the linear velocity of the transport of the document 16 so that the folds 56 of the document 16 can be spaced out and brought back into the plane of the document 16 as shown in FIG. Can be driven at surface speed.

Although the document 16 shown in FIGS. 6A, 6B, and 6C was not shown as having longitudinal folds 22, the document 16 shown in FIGS. 6Δ, 6B, and 6B was It should be appreciated that a longitudinal fold 22 may also be included.

The invention and its embodiments so far described have the advantage of regulating the document 16, such that it can be handled by prior art document handling devices after passing through the transport device described for the invention. Therefore, the present invention can be used simply as a document adjustment station without the need to rotate the class 16 through any angle. Therefore, the document 16 is transferred to the border 20.5 by the driver 38.28.
2, it is only necessary that the rack 10 be bent by a small enough angle to break the longitudinal bend 22. Similarly, the brake cylinders 3 cooperate to reduce and eliminate obstacles to document advancement caused by corner folds 56.
0 and the border 20.52 function of the document handling device for the removal of the corner fold 56 and for the readjustment of the corner fold 56 that reestablishes itself during the transport of the document 16. It can be used separately at the beginning as well as throughout.
