Description
Description Title of Invention: DOCUMENT TRANSPORTER
Technical Field [0001] This invention relates to a document transporter for transporting a document such as a bill along and in alignment with a passageway.
Background Art [0002] One of known bill transporters comprises an aligning or a centering device that may automatically bring a bill into alignment with a passageway when the bill is inserted into the passageway in the deviated or inclined condition of the bill from a longitudinal central axis of the passageway. For example, Patent Document 1 below listed discloses a self aligning transport apparatus for variable media that comprises a passageway and a plurality of rotors aligned substantially parallel to side walls of the passageway, wherein at least one of the rotors has a surface shaped to drive the media in an in-termittent fashion in a direction longitudinal to the passageway so as to align the media substantially with the side walls when the media is free to rotate about each rotor. In this mechanism, the media is intermittently driven to intermittently bring the surface of the rotor into contact to the media, and at the point where the rotor becomes disengaged from the media, the distorted media releases its strain energy accumulated upon contact to a side wall of the passageway to automatically bring the media in alignment with the passageway so that the media may be transported along the passageway. However, the apparatus of Patent Document 1 naturally needs the mechanism for intermittently bringing the rotor into contact to valuable media while resulting in increased abrasion in rotor which therefore must be exchanged for new one at fixed intervals.

However, the apparatus of Patent Document 1 naturally needs the mechanism for intermittently bringing the rotor into contact to valuable media while resulting in increased abrasion in rotor which therefore must be exchanged for new one at fixed intervals.
[0003] Patent Document 2 undermentioned represents a banknote drive system that comprises a series of drive rollers located in a banknote guide channel and an as-sociated passive roller positioned opposite to drive rollers and having a flattered or notched portion to transport a banknote while gripping it between the drive roller and passive roller wherein flattered or notched potion defines a gap to pass the banknote through the gap during the stoppage of the passive roller's rotation so as to allow alignment of the banknote with a guide channel in the system. The banknote drive system shown in Patent Document 2 disadvantageously requires a stop mechanism made up of a spiral cam surface formed with a stop face and a spring latch with which stop face of the cam surface is brought into engagement to stop rotation of the passive roller. This stop mechanism undesirably prevents continuous and smooth rotation of the passive roller and leads to complicated structure in the system.
[0004] The following Patent Document 3 demonstrates a banknote centering device that comprises an enlarged slot for receiving a banknote longitudinally, side engaging members associated with the slot and movable from an open position either side of the slot to a narrow position defining a minimum position between the side engaging members, a banknote drive mechanism for driving a banknote from an insert position to a centering position where the banknote is freely centered within the slot, a side engaging member drive arrangement for moving the side engaging members in a controlled manner towards one another and equally spaced either side of a centerline of the slot. The side engaging member drive arrangement includes a motor for ac-celerating the side engaging members from the open position towards the narrow position until further inward movement of the side engaging members is opposed by the sides of a banknote being parallel therewith and contacting the side engaging members over a substantial length thereof centering the banknote in the slot.
The drive arrangement of the side engaging members includes a screw drive in drive connection with the side engaging members, and the screw drive includes a second shaft parallel to the common shaft to maintain the side engaging members appropriately spaced by the screw drive during movement between the open and narrow positions. The banknote centering device of Patent Document 3 unfavorably demands the side engaging members and the side engaging member drive arrangement for moving the side engaging members towards one another.

[0005] Patent Document 4 below exhibits an aligning and reading apparatus for a bill that comprises first transporters for laterally conveying a bill along a passageway when one kind of bills having their different longitudinal length is supplied into the passageway, an alignment arrangement for centering the bill toward a longitudinal center of the passageway by urging inwardly the opposite ends of the bill conveyed by the first transporters, second transporters located on quarto lines of the bill for further conveying the centered bill, and a reading head located away from the quarto lines of the bill for detecting features of the bill. The apparatus shown in Patent Document 4 disadvantageously has the increased number of assembled elements and cannot be cut down the cost for manufacture because it calls for the alignment arrangement for centering the bill toward a longitudinal center of the passageway by urging inwardly the opposite ends of the bill.

Patent No. 6,149,150 PTL 4: Japanese Patent Disclosure No. 55-115891 Summary of Invention Technical Problem [0007] Thus, prior art apparatuses utilize an alignment or centering device of its complicated structure that undesirably leads to costly processes for manufacture with limited reduction in cost for manufacture. Accordingly, an object of the present invention is to provide a document transporter of the simplified structure capable of aligning a transported document with a passageway for the bill.
Solution to Problem [0008] The document transporter according to the present invention comprises a passageway (2) and a conveyor (3) for transporting a document (1) along passageway (2).
Conveyor (3) comprises a frictional carrier (4) rotatably mounted in passageway (2), a drive device (5) for driving frictional carrier (4) and a weighting device (7) for urging document (1) against frictional carrier (4). Weighting device (7) comprises a holder (8) adjacent to passageway (2), and a sphere (6) rotatably maintained in holder (8) to be in contact to frictional carrier (4) to grip document (1) between sphere (6) and frictional carrier (4). When document (1) is inserted into passageway (2) with the deviated or inclined central axis of document (1) relative to a longitudinal central axis of passageway (2), document (1) is gripped between sphere (6) and frictional carrier (4), and at the time, either side edge (1 a) of document (1) comes into contact to a side wall (13) of passageway (2), and side wall (13) of passageway (2) causes flexible document (1) to elastically deform while emerging a restoring force in deformed document (1) to turn back to its original undeformed flat shape. This restoring force in document (1) may produce a reactive force that tends to separate the side edge (1 a) of document (1) off from side wall (13) of passageway (2) so as to move and bring document (1) into alignment with a longitudinal central axis of passageway (2). At that time, as sphere (6) in contact to moving document (1) rotates or makes a spherical motion within holder (8) depending on document (1) moving in any planar radial direction from a contact point with sphere (6) within passageway (2), a frictional force of sphere (6) on document (1) is very small, while the resultant reactive force is greater than the frictional force to sphere (6). Accordingly, document (1) can freely move within a two-directional plane containing the contact point with sphere (6) to release the reactive force so that document (1) moves to come into alignment with a longitudinal central axis of passageway (2) for automatic centering.
Advantageous Effects of Invention [0009] The present invention can provide an inexpensive document transporter of its simplified structure capable of automatically aligning a transported document with a passageway to certainly validate the aligned document by means of a discrimination sensor mounted in the back of the passageway.

Description of Embodiments [0011] Embodiments of the document transporter according to the present invention will be described hereinafter in connection with Figures 1 to 16 of the drawings. A
word "document" used herein means a bill, a banknote, a coupon, a security, tender, scrip of money equivalence or one of all economically valuable papers.
[0012] Figures 1 to 7 illustrate a first embodiment of the bill transporter according to the present invention. As shown in Figure 1, the bill transporter comprises a passageway 2 and a conveyor 3 for transporting a bill 1 as a document inserted into passageway 2.
Passageway 2 comprises a bottom wall 11, a top wall 12 and side walls 13 all formed of plastic or metallic materials. Conveyor 3 comprises a frictional carrier 4 rotatably mounted in passageway 2, a drive device 5 for driving frictional carrier 4 and a weighting device 7 for urging or pressing bill 1 against a conveyor belt of frictional carrier 4. While the shown embodiments instantiate frictional carrier 4 utilizing a conveyor belt, however, it may utilize a conveyor roller or conveyor rollers accessible to bill 1 in lieu of conveyor belt.
Passageway 2 comprises a bottom wall 11, a top wall 12 and side walls 13 all formed of plastic or metallic materials. Conveyor 3 comprises a frictional carrier 4 rotatably mounted in passageway 2, a drive device 5 for driving frictional carrier 4 and a weighting device 7 for urging or pressing bill 1 against a conveyor belt of frictional carrier 4. While the shown embodiments instantiate frictional carrier 4 utilizing a conveyor belt, however, it may utilize a conveyor roller or conveyor rollers accessible to bill 1 in lieu of conveyor belt.
[0013] Weighting device 7 comprises a holder 8 formed adjacent to passageway 2, and a sphere or ball 6 rotatably maintained in holder 8 to be accessible to or in contact to conveyor belt of frictional carrier 4 to grip bill 1 between ball 6 and conveyor belt of frictional carrier 4. As seen in Figures 1 and 3, frictional carrier 4 is drivingly mounted within a chamber 14 formed in a bottom wall of passageway 2. Drive device 5 comprises a drive motor 20 that is drivingly connected to frictional carrier 4 through a power transmission device 21 of a desired reduction gear ratio. Power transmission device 21 may comprise a gear train, a belt transmission or their combination.
[0014] Holder 8 is formed in a top wall 12 of conveyor 3 for defining passageway 2 to arrange ball 6 in holder 8 that comprises a vertically formed cylindrical hole 8b, an inner bearing surface 8a formed at a lower portion of cylindrical hole 8b into a partially spherical shape and an opening 8c formed at the bottom of holder 8 for com-municating inner bearing surface 8a with passageway 2. Ball 6 is in contact to inner bearing surface 8a to freely rotate, roll, make a spherical motion or slide in all or any directions within inner bearing surface 8a when in contact to bill 1, and also to vertically move in holder 8 toward and away from passageway 2. When bill 1 is inserted between ball 6 and conveyor belt of frictional carrier 4, it comes into contact to ball 6 urged downwardly by its own gravity, and ball 6 may freely rotate within inner bearing surface 8a in accordance with the moving direction of bill 1 that may be easily and smoothly moved in any and all radial directions of 360 angular degrees in a planar surface from a contact point between ball 6 and bill 1 even though bill 1 is gripped between ball 6 and conveyor belt of frictional carrier 4. Also, ball 6 may be in contact to bill 1 at its any and all spherical outer surfaces to urge bill 1 on conveyor belt of frictional carrier 4 under a constant pressure by its own gravity.
Ball 6 may freely rotate and slide within holder 8 with an extremely less amount of resultant frictional force between ball 6 and bill 1 compared to a case of the sliding contact only, and also, ball 6 may upwardly move within holder 8 when any external force is applied to ball 6 from the bottom.
Ball 6 may freely rotate and slide within holder 8 with an extremely less amount of resultant frictional force between ball 6 and bill 1 compared to a case of the sliding contact only, and also, ball 6 may upwardly move within holder 8 when any external force is applied to ball 6 from the bottom.
[0015] Conveyor belt in frictional carrier 4 is formed of any plastic material with its outer surface covered with rubber materials of larger friction coefficient in contact to moved bill 1 and ball 6. Even where frictional carrier 4 comprises a conveyor roller in place of conveyor belt, such a conveyor roller may have its outer surface coated with a rubber material of larger friction coefficient. Ball 6 is made of a material selected from the group of corrosive-resistant materials such as stainless steel, iron or ferric alloy, and in a structure of ball 6 resiliently urged toward frictional carrier 4 by a spring 15, ball 6 may be made of a relatively light metal such as copper, titanium, aluminum or their alloy or wear-resistant plastic materials.
[0016] An inner diameter of opening 8c in holder 8 is smaller than an outer diameter of ball 6 to keep ball 6 within holder 8 without downward drop of ball 6 that however can move upwardly within holder 8. As shown in Figure 4, a bottom portion of ball retained in holder 8 projects into passageway 2 through opening 8c of holder 8 and makes contact to conveyor belt of frictional carrier 4 that upwardly projects into passageway 2 from bottom wall thereof so that bottom portion of ball 6 also makes contact to bill 1 in touch with conveyor belt of frictional carrier 4 while bill 1 moves between ball 6 and conveyor belt of frictional carrier 4 within passageway 2.
[0017] Opposite side walls 13 define passageway 2 and have inwardly tapered surfaces 9 at the front to form an inlet 16. A pair of inlet sensors 10 are arranged in bottom and top walls 11 and 12 in the vicinity of and on the opposite sides of conveyor belt of frictional carrier 4 to detect bill 1 inserted into passageway 2. Not shown in the drawings, but, each of inlet sensors 10 may have a photo-coupler of light emitting and receiving elements for detecting light-interruption between these elements by bill 1 moving through passageway 2. When any inlet sensor 10 detects light-interruption by passage of bill 1, it produces a detection signal to a control device (not shown) that in turn effects a trigger signal to drive device 5 to activate drive device 5 and thereby drive frictional carrier 4. At that moment, ball 6 makes contact to rotating conveyor belt of frictional carrier 4 and thereby rotates within inner bearing surface 8a of holder 8, and when ball 6 makes spherical contact to bill 1 inserted into passageway 2, it may freely rotate within inner bearing surface 8a of holder 8 in accordance with movement of bill 1 through passageway 2 if bill 1 moves in any planar direction in passageway 2.
[0018] The embodiment shown in Figure 4 illustrates an example of the structures wherein ball 6 makes contact to conveyor belt of frictional carrier 4 or bill 1 under its own weight in other words at a given pressure, and this structure has the feature capable of maintaining a constant pressure on bill 1 by ball 6 without effecting any change to pressure by ball 6 on conveyor belt of frictional carrier 4 and on bill 1 even though ball 6 rotates within inner bearing surface 8a of holder 8. If rotating ball 6 has any frictional force on bill 1, it is smaller than a frictional force by bill 1 on frictional carrier 4.
[0019] When bill 1 is inserted into passageway 2 with the deviated or inclined central axis of bill 1 relative to a longitudinal central axis of passageway 2 on a plane surface as shown in Figure 5, bill 1 is gripped between ball 6 and conveyor belt of frictional carrier 4, and at the time at least one or both of side edges la of bill 1 come into contact to either or both side walls 13 of passageway 2, side wall or walls 13 cause flexible bill 1 to elastically deform while inducing a restoring force in deformed bill 1 to turn back to its original undeformed flat shape. This restoring force in bill 1 may produce a reactive force that tends to separate side edge or edges la of bill 1 off from side wall or walls 13 of passageway 2 so as to move and bring bill 1 into alignment with a longitudinal central axis of passageway 2. At that time, as ball 6 in contact to moving bill 1 rotates or makes a spherical action within holder 8 depending on bill 1 moving in any planar radial direction from a contact point with sphere 6 within passageway 2, a frictional force of ball 6 on bill 1 is very small, while the resultant reactive force is greater than frictional force to ball 6. Accordingly, bill 1 can freely move within a two-directional plane containing the contact point with ball 6 to release the reactive force in bill 1 in contact to ball 6 so that bill 1 moves to come into alignment with a longitudinal central axis of passageway 2 for automatic aligning or centering of bill's attitude. In this way, this invention may provide an inexpensive bill transporter of its simplified structure capable of automatically aligning a transported bill with a passageway.
[0020] Figure 7 illustrates a variation from the embodiment in Figure 4 with the vertically inverted structure of ball 6 and frictional carrier 4 wherein frictional carrier 4 is rotatably arranged in chamber 14 of top wall 12 in conveyor 3; holder 8 is formed in bottom wall 11 of conveyor 3; and ball 6 is disposed in holder 8 to upwardly and elastically urge ball 6 toward conveyor belt of frictional carrier 4 by a resilient force of a spring 15 as an elastic material so that ball 6 makes contact to bill 1 moving between ball 6 and frictional carrier 4. In the embodiment shown in Figure 7, as ball 6 is arranged under conveyor belt of frictional carrier 4 without exerting ball's own gravity on bill 1, spring 15 is used to upwardly and elastically urge ball 6 to produce a prede-termined elastic force on bill 1 toward conveyor belt of frictional carrier 4.
However, if any downward external force is applied to ball 6, it can downwardly move against resilient force of spring 15. Even this embodiment can produce its performance and effect equivalent to those of the structure shown in Figures 1 to 6 because spring 15 may exert an unchanged pressing force of a constant level on bill 1 through ball 6 at any spherical outer surface of ball 6 in contact to bill 1.

[0021] Figures 8 to 16 represent a second embodiment of the invention wherein two pairs of guide rollers 22 are rotatably arranged face-to-face each other and attached to opposite side walls 13 of passageway 2 shown in Figures 1 to 7. In the second embodiment, each guide roller 22 has an outer rim formed with a V- or U-shaped annular groove 23 into which a side edge of bill 1 may be fit, and each of side walls 13 of passageway 2 has an intermediate surface formed into an arcuate shape between anterior and posterior guide rollers 22.
[0022] As shown in Figures 11 to 16, when bill 1 is inserted into passageway 2 with the deviated bill's longitudinal axis from longitudinal central line of passageway 2, side edges of bill 1 come into contact with guide rollers 22 which therefore are rotated upon contact with bill 1 so that guide rollers 22 may smoothly modify the moving direction of bill 1 to bring bill 1 into alignment with passageway 2. Then, as shown in Figures 15 and 16, bill 1 is finally easily rendered aligned and coaxially with passageway 2 during movement of bill 1.
