A configuration in which a plurality of are connected is also included.

Next, operations of the paper sheet sorting apparatus and the paper sheet top and bottom arrangement apparatus according to this embodiment will be described.
As shown in FIG. 1, banknotes are carried into the banknote organizing apparatus 1 in a direction perpendicular to the longitudinal direction. The banknotes carried into the banknote organizing apparatus 1 are discriminated by the front / back / top / bottom and top / bottom determination apparatus 2. The banknote in the front state is turned into the reverse state by the front / back reversing device 3a in the banknote front / back arrangement device 3 and carried out of the banknote front / back arrangement device 3, and the banknote in the reverse state is bypassed in the banknote front / back arrangement device 3 It passes through 3b and is carried out from the banknote front / back arrangement device 3 as it is. The banknotes carried out from the banknote front / back arrangement device 3 are arranged in the reverse state, but are carried into the banknote top / bottom arrangement device 4 in a state where the top and bottom are separated. In the banknote top and bottom arrangement device 4, the top and bottom of the banknotes and the top and bottom of the banknotes are aligned by reversing the top and bottom of the banknotes by the operation described below.

  Since the front / back and top / bottom of the banknote is discriminated by the front / back / top / bottom discriminator 2, the top / bottom state of each banknote carried into the banknote / top / bottom organizer 4 is known in advance before being carried into the banknote top / bottom sorter 4. Yes. As shown in FIG. 2, in the banknote top and bottom arrangement device 4, individual banknotes are transferred between the first conveyance fixing roller 22 and the first conveyance fixing roller 24 and the second conveyance fixation roller 26 and the second conveyance in the carry-in unit 11. When the first sensor 20 detects passage of the bill after passing between the fixed rollers 28, the solenoids 75 and 76 are operated according to the state of the bill (lining and lining). When the banknotes carried into the banknote top and bottom arrangement device 4 are in a lined state, the solenoids 75 and 76 extend the pistons 73 and 74, respectively, so that the respective carry-in movable rollers 43 and the respective carry-out movable rollers 44 are fixed to the third conveyance. The first movable roller 54 and the second movable roller 55 are in contact with the roller 42 and are separated from the direction change fixed rollers 53 (the state shown in FIG. 2). In this state, since the banknote is not sandwiched between the first movable roller 54 and the direction conversion fixed roller 53, the banknote conveyed by the carry-in unit 11 passes through the direction conversion inversion unit 14.

  As shown in FIG. 8, the banknote in a lined state carried into the banknote top and bottom arrangement device 4 is conveyed by the carry-in unit 11 and then conveyed to the reversing unit 12 after passing through the direction changing / reversing unit 14. In the reversing unit 12, the banknote passes between the carry-in movable roller 43 (see FIG. 2) and the third transport fixing roller 42 and is carried into the first reversing means 34. In the first reversing means 34, the banknotes are third reversal between the first reversing roller 47 (see FIG. 2) and the fourth transport fixing roller 46, between the second reversing roller 48 and the fourth transport fixing roller 46. By being sequentially transported between the roller 49 (see FIG. 2) and the fourth transport fixing roller 46, the front and back are reversed along the transport direction to be in an upright state. As shown in FIG. 2, the banknote in the top-facing state that has passed between the third reversing roller 49 and the fourth transport fixing roller 46 has the third transport fixing roller 42 and the transporting movable roller 44 in the reversing unit transporting unit 35. Between the second transport fixing roller 26 and the second transport fixing roller 26. The second transport fixing roller 26 and the second transport fixing roller 26 are transported in the direction opposite to the direction transported by the reversing unit carry-in means 33. By passing between the fixed rollers 32, it is discharged from the banknote top-and-bottom arrangement device 4 in an upright state.

  As can be seen from FIG. 8, since the side surfaces 53a and 53b of the direction conversion fixing roller 53 face perpendicularly to the banknote transport direction, the banknote transport direction when the banknote passes through the direction conversion reversing unit 14. May collide with the side surfaces 53a and 53b of the direction change fixing roller 53. However, because the peripheral edge portions of the side surfaces 53a and 53b of the direction change fixing roller 53 are chamfered (refer to FIG. 7B for details), the leading edge portion of the banknote moves along the chamfered peripheral edge portion. Therefore, it is possible to smoothly pass the banknotes through the direction changing and fixing roller 53, and thus it is possible to prevent the banknotes from being crushed by the side surfaces 53 a and 53 b of the direction changing and fixing roller 53.

On the other hand, when the banknotes carried into the banknote top and bottom arrangement device 4 are in the back-up state, as shown in FIG. 6, the solenoids 75 contract the pistons 73, so that each carry-in movable roller 43 is fixed to each third transport. While separating from the roller 42, each first movable roller 54 comes into contact with each direction changing fixed roller 53. In this state, the banknote conveyed by the carry-in unit 11 is sandwiched between the first movable roller 54 and the direction-changing fixed roller 53 in the direction conversion reversing unit 14 and is conveyed by these. In addition, when the solenoid 76 contracts the piston 74 at a timing to be described later, each unloading movable roller 44 is separated from each third transport fixed roller 42, and each second movable roller 55 is in contact with each direction conversion fixed roller 53. It becomes.

  In this state, the banknote in the back-up state carried into the banknote top and bottom arrangement device 4 is transported by the carry-in unit 11 and then the first movable roller 54 ( 6) and the direction changing fixed roller 53, the conveyance direction is changed in a direction perpendicular to the direction conveyed by the carry-in unit 11. The banknotes conveyed by the first movable roller 54 and the direction changing fixed roller 53 are carried into the second reversing means 52. In the second reversing means 52, the bills are transferred between the fourth reversing roller 59 (see FIG. 5) and the reversing feed roller 58, between the fifth reversing roller 60 and the reversing feeding roller 58, and the sixth reversing roller 61 (see FIG. 5). 5) and the reverse feed roller 58 are sequentially transported, so that the front and back are reversed along the transport direction to be in the top and bottom state.

  As shown in FIG. 5, after the bill is conveyed between the fifth reverse roller 60 and the reverse feed roller 58, when the second sensor 62 detects the passage of the bill, the solenoid 76 moves the piston 74 at this timing. Is contracted to bring the second movable rollers 55 into contact with the direction change fixed rollers 53. Then, the banknotes conveyed by the sixth reverse roller 61 and the reverse feed roller 58 are conveyed by the second movable roller 55 and the direction changing fixed roller 53, and the leading edge of the banknote with respect to the conveyance direction is eventually transferred to the second conveyance stopper 50. Collide with. At this timing, the solenoid 76 extends the piston 74, whereby each second movable roller 55 is separated from each direction changing fixed roller 53, and the bill is not conveyed by the second movable roller 55 and the direction changing fixed roller 53. When each second movable roller 55 is separated from each direction converting fixed roller 53, the carry-out movable roller 44 comes into contact with the third conveyance fixed roller 42, so that the bill is transferred between the carry-out movable roller 44 and the third conveyance fixed roller 42. The paper money is conveyed to the carry-out section 13 (see FIG. 2) by the carry-out movable roller 44 and the third conveyance fixed roller 42 between the two. As shown in FIG. 2, in the carry-out unit 13, the banknotes are discharged from the banknote top and bottom arrangement device 4 in a face-up state by the second transport fixing roller 26 and the carry-out fixing roller 32.

  As shown in FIG. 5, when the bill is transported by the direction changing fixed roller 53 and the second movable roller 55, the bill moves in a direction perpendicular to the side surface 42 a of the third transport fixed roller 42. To do. At this time, there is a possibility that the front end portion in the bill conveyance direction collides with the side surface 42a of the third conveyance fixing roller 42. However, the peripheral portion of the side surface 42a of the third conveyance fixation roller 42 is chamfered (details). 7 (a)), the leading edge of the banknote can move along the chamfered peripheral edge, so that the banknote can smoothly pass through the third transport fixing roller 42. It is possible to prevent the third conveyance fixing roller 42 from being crushed by the side surface 42a. In this embodiment, since the banknote does not collide with the side face 42b of the third transport fixing roller 42, the side face on the second reversing means 52 side among the both side faces of the third transport fixing roller 42. Only the peripheral edge of 42a may be chamfered.

  In addition, as shown in FIG. 6, when the first movable roller 54 comes into contact with the direction changing fixed roller 53 and the conveyance direction of the bill is changed by these, the first conveyance stopper 78 is the third conveyance. It is inserted between the fixed roller 42 and the fourth conveying fixed roller 46. Thereby, a banknote is prevented from being conveyed to the inversion part 12. FIG. In the state of FIG. 6, the banknotes conveyed by the carry-in unit 11 are conveyed to the second reversing means 52 by the first movable roller 54 and the direction-changing fixed roller 53 in the direction converting / reversing unit 14, so in principle the reversing unit. However, when the banknote transported by the carry-in unit 11 is inclined, a part of the banknote is sandwiched between the first reverse roller 47 and the fourth transport fixing roller 46. There is a risk of being sent to the reversing unit 12. However, since the first conveyance stopper 78 is inserted between the third conveyance fixing roller 42 and the fourth conveyance fixing roller 46, the bill collides with the first conveyance stopper 78 and is inclined obliquely. The condition is corrected. Thereby, while being able to prevent a banknote being sent to the inversion part 12, the banknote which passed the direction change inversion part 14 in the state inclined diagonally collided with the banknote which passed the inversion part 12 in the inversion part carrying out means 35. Can also be prevented.

  In addition, in FIG. 9 (a), the locus | trajectory for the banknote of a lining state to a surface-up state is shown in FIG. Shown in b). As can be seen from these trajectories, the banknote entrance and exit of the banknote top and bottom arrangement apparatus 4 are configured close to the direction in which the banknotes are conveyed.

  Thus, since it can be set as the structure which the entrance and exit of the banknote adjoined with respect to the direction in which a banknote is conveyed, making the banknote top and bottom arrangement apparatus 4 which can arrange the top and bottom of a banknote compact can be made. it can. Moreover, since the banknote top and bottom organizing apparatus 4 according to this embodiment is compact, even if the banknote top and bottom organizing apparatus 4 is added to a conventional banknote top and bottom organizing apparatus having a known banknote front and back side organizing apparatus, the size of the banknote rearranging apparatus is large. Can be almost maintained. For this reason, the banknote arrangement device which can arrange the front and back and top and bottom of banknotes can also be made compact.

  In this embodiment, as the paper sheet sorting apparatus, the banknote sorting apparatus 1 that aligns the front and back sides of the banknotes and the top and bottom has been described as an example. However, the present invention is not limited to this. The paper sheets are not limited to banknotes, and may be arbitrary ones such as voting papers. Therefore, the paper sheet classification device is a paper ballot sorting device or the like depending on the type of paper sheets. The thing which can arrange the front and back and top and bottom of leaves may be sufficient.
