An identification unit 12 for identifying the denomination, front / back, authenticity, etc. of the banknote P is provided in the middle of the first transport path 11.

  Second and third transport paths 14 and 15 are connected to the downstream side of the first transport path 11 in the banknote transport direction via a switching gate 13. The 2nd conveyance path 14 conveys the banknote P to the 1st thru | or 3rd discharge parts 3a-3c mentioned above. The first and second switching gates 17 and 18 are disposed in the middle of the second transport path 14, and the bills P are moved from the first to the second by the switching operation of the first and second switching gates 17 and 18. It is selectively conveyed to the 3rd discharge parts 3a-3c. Discharge roller pairs 20a to 20c for discharging the banknotes P are disposed on the lower side of the first to third discharge portions 3a to 3c.

  On the other hand, a front / back reversing mechanism 22 as a reversing unit is connected to the downstream side of the third transport path 15 in the bill transport direction. The banknotes whose front and back surfaces are aligned by the front / back reversing mechanism 22 are transported to the stacking unit 26 via the fourth transport path 24 and stacked. A predetermined number of banknotes P, for example 100, are stacked on the stacking unit 26.

  A transport mechanism 28 that transports the stacked banknotes to the sealing unit 30 is provided below the stacking unit 26. The transport mechanism 28 includes a transport belt 44 that runs across a plurality of rollers 43, and the stacked banknotes are placed on the top surface of the transport belt 44 and transported.

  The sealing unit 30 includes a clamp member (not shown) that clamps and receives the stacked banknotes transported by the transport belt 44 from above and below, and a tape winding that winds the binding tape 36 around the banknotes P held between the clamp members. An attaching mechanism 33, a cutter 34 for cutting the binding tape 36 into a predetermined length, a heater 35 for thermally bonding the overlapping end portion of the binding tape 36, and the like are provided. The tape winding mechanism 33 includes a pair of winding arms 46 that are rotatable.

  The binding tape 36 is supplied from the supply reel 37 along the supply route 38, and a printing unit 40 is provided in the middle of the supply route 38 to print the bank branch name, processing date, serial number, etc. on the binding tape 36. ing. The printing unit 40 includes a printing head 41 and a platen roller 42 facing the printing head 41.

  Next, the processing operation of the above banknote sorter will be described.

  First, the mixed denomination banknotes P are placed in a stacked state on the placement portion 2 of the apparatus main body 1, and the count classification processing mode or the bundling processing mode is set by the operation portion 4.

  From this state, the take-in rollers 7a and 7b are rotationally driven. Thereby, the banknote P is taken in, and the banknote P is separated and supplied one by one by the rotation of the supply roller 8 and the separation roller 9. The banknote P is sent to the identification unit 12 via the first transport path 11 and identified.

  For example, when the counting / sorting processing mode is set by the operation unit 4, the identified banknote is conveyed toward the first to third discharge units 3 a to 3 c via the second conveyance path 14. . When the identified banknote is, for example, a thousand-yen note, the first sorting gate 17 moves to the first discharge roller pair 20a, and the rotation of the first discharge roller pair 20a causes the first discharge roller pair 20a to rotate. 1 is discharged to the discharge unit 3a. When the identified banknote is, for example, a 10,000 yen bill, it is sent to the second discharge roller pair 20b by the operation of the second sorting gate 18, and the second discharge roller pair 20b rotates to rotate the second discharge roller pair 20b. It is discharged to the discharge unit 3b. When the identified banknote is, for example, an unidentifiable banknote such as a double banknote, a chained banknote, a fake banknote, or a denomination banknote other than the classified denomination banknote, it is sent to the third discharge roller pair 20c. 3 is discharged as a reject ticket to the third discharge portion 3c by the rotation of the pair of discharge rollers 20c.

  Further, when the bundling processing mode is set by the operation unit 4, if the denomination of the banknotes to be bound is designated in advance, the banknote of the designated denomination is transferred to the third transport path 15 via the switching gate 13. Is sent to the front / back reversing mechanism 22 without being discharged to any of the discharge portions 3a to 3c. The banknotes sent to the front / back reversing mechanism 22 are sent to the stacking unit 26 via the fourth transport path 24 after being aligned on one surface.

  At this time, banknotes other than the designated denomination are discharged to the first to third discharge units 3a to 3c in the same manner as in the counting and sorting process mode.

  When a predetermined number of banknotes (for example, 100) are stacked on the stacking unit 26, the banknotes are transferred from the stacking unit 26 onto the transport belt 44. The transferred stacked banknotes are transported to the sealing unit 30 by the travel of the transport belt 44 and are gripped by a gripping piece (not shown). At this time, the binding tape 36 is supplied from the supply reel 37, and the name of the bank branch, the date of processing, the serial number, and the like are printed on the surface of the binding tape 36 by the printing unit 40. When the binding tape 36 is fed out by a predetermined length, it is cut by the cutter 34 and then wound around the stacked banknotes by the rotation of the pair of winding arms 46. After this winding, the heater 35 is pressed against both ends of the binding tape 36 and heated. As a result, the binding tape 36 is bonded and bound, and the bundled banknote bundle is released and stored in the storage unit.

  Next, the mounting unit 2 described above will be described in detail.

  FIG. 3 is a configuration diagram showing the placement unit 2.

  The placement unit 2 includes a horizontal placement surface 51 and a guide surface 52 that rises substantially perpendicular to the placement surface 51. The placing surface 51 places a stacked banknote, and the guide surface 52 is used as a guide when placing the stacked banknote.

  The placement section 2 is provided with a backup 54 as a pressing means for pressing the upper surface portion of the stacked banknotes placed on the placement surface 51. The backup 54 is moved between a pressing position A for pressing the upper surface portion of the stacked banknotes by a driving mechanism 55 as driving means and a storage portion B as a retracting position for retracting from the pressing position A. . The storage part B is provided along the guide surface 52.

  The drive mechanism 55 has a backup arm 57 as a rotation arm, and a backup 54 is rotatably attached to one end of the backup arm 57 via a support shaft 57a. The other end of the backup arm 57 is connected to the drive shaft 59 via a torque limiter 58. The drive shaft 59 is connected via a power transmission mechanism 60 to a drive motor (not shown) that rotates forward and backward.

  When the drive motor rotates in the forward direction, the backup arm 57 is rotated clockwise via the drive shaft 59 and the torque limiter 58 and moved to the pressing position A to press the upper surface portion of the stacked banknotes. Further, when the drive motor rotates in the reverse direction, the backup arm 57 is rotated counterclockwise via the drive shaft 559 and the torque limiter 58 and retracted from the pressing position A and stored in the storage portion B.

  On the other hand, a human sensor 62 is provided in the vicinity of the placement unit 2 as shown in FIG. 4, and a detection sensor 64 as a detection means is provided as shown in FIG.

  The human sensor 62 detects a worker's hand when an additional bill is inserted, and the detection sensor 64 detects whether or not the stacked amount of the bills placed on the placement surface 51 is a certain amount or more. Is.

  A switch may be provided instead of the human sensor 62.

  FIG. 6 is a block diagram showing the drive control system of the backup 54 described above.

  The human sensor 62 and the detection sensor 64 described above are connected to a control unit 65 as control means via a signal transmission circuit, and the drive mechanism 55 of the backup 54 is connected to the control unit 65 via the control circuit. . The drive mechanism 55 is connected to an operation determination unit 66 for detecting the end of the processing operation in the counting / classification processing mode or the bundling processing mode, and the backup 54 is driven from the pressing position A to the storage unit B in response to the end of the processing operation. Is done.

  The control unit 65 detects that the banknote stacking amount is equal to or less than a predetermined amount when the banknote sorter is performing the processing operation in the counting / sorting processing mode or the bundling processing mode. Based on the above, the backup arm 57 is rotated clockwise to move the backup 54 from the storage portion B to the pressing position A.

  In addition, the control unit 65 transmits a detection signal from the human sensor 62 or presses the switch when the banknote sorter is set to the counting / sorting processing mode or the bundling processing mode to perform the processing operation. Based on this, the backup arm 57 is rotated counterclockwise to move the backup 54 from the pressing position A to the storage portion B.

  Note that when the banknote sorter finishes the processing operation in the counting / classification processing mode or the bundling processing mode, the operation determination unit 66 does not matter whether there is a detection signal from the human sensor 62 or an operation signal from the switch. Upon detection, the backup arm 57 is rotated counterclockwise to move the backup 54 from the pressing position A to the storage portion B.

  Next, the operation of placing a bill on the placement unit 2 and the operation of taking the placed bill will be described.

  First, as shown in FIG. 4, the stacked banknotes are placed on the placement surface 51 in a state where the backup 54 is retracted and stored in the storage portion B. The amount of the stacked banknotes placed is detected by the detection sensor 64, and when the stacking amount is a certain amount or more, the weight of the stacked banknotes is sufficient between the lower surface portion of the stacked banknotes and the take-in rollers 7a and 7b. Since the frictional force is generated, the take-up rollers 7a and 7b are rotated in a state where the backup 54 is stored in the storage portion B, and the bill is taken in.

  If the stacking amount of the banknotes is reduced by this capture and the detection sensor 64 detects that the stacking amount has become a certain amount or less, as shown in FIG. It moves to the pressing position A and presses the upper surface of the stacked banknote. Thereby, the lower surface part of a lamination | stacking banknote is pressed against taking-in roller 7a, 7b, sufficient frictional force generate | occur | produces, and a banknote is taken in by rotation of taking-in roller 7a, 7b.

  In addition, at the time of taking in, when an additional banknote is inserted, the worker brings his hand close to the human sensor 62. Accordingly, the hand is detected by the human sensor 62 and the detection information is transmitted to the control unit 65. By this transmission, the backup 54 moves from the pressing position A to the storage portion B and is stored. After the backup 54 is retracted in this manner, the additional banknote can be placed on the upper surface of the stacked banknote and the processing operation can be continued.

  Note that, when the stacked bills are placed on the placement surface 51 and the detection sensor 64 determines that the amount of the stacked bills is equal to or less than a certain amount, as shown in FIG. It moves to the press position A from the storage part B, presses the upper surface part of a laminated banknote, and takes in a banknote.

  As described above, according to this embodiment, since the drive shaft 59 and the backup arm 57 are connected via the torque limiter 58, excessive torque is not transmitted to the backup 54, and a machine failure is prevented. In addition, the safety of the user can be sufficiently ensured even when a finger or the like is pinched when the backup is pressed or moved to the storage unit.

  Further, when the banknotes are additionally inserted, the backup 54 is retracted from the pressing position A to the storage portion B, so that the backup 54 does not get in the way and the additional banknote insertion work can be easily performed.

  Of course, the present invention is not limited to the above-described embodiment, but can be variously modified within the scope of the gist thereof.
