FIG. 1 is an explanatory view showing the relationship between the deterioration of the rigidity of the banknote and the bending. Generally, the rigidity of banknotes gradually deteriorates according to the frequency of use. FIG. 1 (a) is an image diagram showing the deflection of a “correct ticket” that is judged to have no problem even if the rigidity has not deteriorated and is re-introduced into the market. Further, FIG. 2B is an image diagram showing the deflection of the “damaged ticket” in which the rigidity is deteriorated and it is determined that re-introduction to the market is inappropriate. That is, as the rigidity of the banknote deteriorates, the deflection when the end of the banknote is clamped increases.

  Below, the banknote sorting device, sorting method, and automatic transaction apparatus with reduced rigidity according to the present invention are applied to an automatic cash transaction apparatus for depositing / withdrawing banknotes (hereinafter abbreviated as “automatic transaction apparatus” as appropriate). An example of the case will be described.

As shown in FIG. 2, the automatic transaction apparatus S includes a deposit / withdrawal unit 14, a temporary storage unit 15, a recognition unit 16, a safe unit 17, and a rejection unit 18.

  During the depositing operation, the bills inserted into the depositing / dispensing unit 14 are separated one by one by a transport mechanism (not shown) and fed out to the transport path 2 and transported to the recognition unit 16. The recognizing unit 16 is provided with a discrimination device (not shown) for discriminating the authenticity and denomination of the banknote and determining whether or not it is accepted, and the paper sheet sorting device of the present invention. After the authenticity and denomination are discriminated by the discriminating device, the accepted bills are further subjected to sorting of damage based on rigidity by the paper sheet sorting device of the present invention. The genuine bills whose rigidity has not deteriorated are conveyed to the temporary storage unit 15 and accumulated, and the damaged bills whose stiffness has deteriorated are collected in the paper sheet sorting apparatus of the present invention. In addition, abnormal banknotes that have not been determined to be genuine bills are transported to another transport path that does not reach the paper sheet sorting apparatus of the present invention by a transport path switching unit (not shown), and are sorted for damage. Instead, it is returned to the deposit / withdrawal unit 14 as it is.

  Thereafter, when the operation of confirming the amount to be inserted by the customer is performed, the banknotes (only the correct bills) accumulated in the temporary storage unit 15 are separated one by one by a transport mechanism (not shown) and fed out to the transport path 2, It is conveyed to the unit 17 and collected by denomination. Further, when the transaction is canceled by the customer, the banknotes accumulated in the temporary holding unit 15 are returned to the deposit / withdrawal unit 14. At this time, if there is a banknote accumulated in the paper sheet sorting apparatus of the present invention, the same amount of banknotes is paid out from the safe 17 to the deposit / withdrawal unit 14. Thereby, it is made so that the non-use ticket put into automatic transaction device S does not return to the market. The banknotes accumulated in the paper sheet sorting apparatus according to the present invention are separately judged by the operator as to whether or not they must be collected together with other abnormal banknotes accumulated in the reject unit 18 during the deposit / withdrawal operation. The deteriorated banknotes are collected.

  FIG. 3 is a functional block diagram of the automatic transaction apparatus S. The automatic transaction apparatus S is configured to include each functional element of a control unit 13, a deposit / withdrawal unit 14, a temporary storage unit 15, a recognition unit 16, a safe unit 17, and a rejection unit 18, and the control unit 13 is a CPU (not shown). The operation is controlled by the program to be executed.

<First Embodiment>

The damaged ticket sorting apparatus 1 is installed close to the downstream of the discrimination apparatus (not shown) in the conveyance direction on the conveyance path 2 of the banknote P in the recognition unit 16. As shown in FIG. 4, the damaged ticket sorting apparatus 1 is fed out by a feed roller 3 that is a feed-out means for sending out the bills P that have been conveyed, and a receiving roller 6 that is a receiving means for receiving the sent bills. Recognizing part reject which is a collecting means for collecting the stage 5 and the guide 4 which are the stage part which supports the leading end part of the bent genuine bill and guides it to the receiving roller 6, and the non-conformity card where the leading end part hangs down. And a box 7. The distance between the banknote P holding portion of the feed roller 3 and the upstream end of the stage 5 in the transport direction is L.

  5A and 5B are explanatory views of the banknote P sorting operation by the banknote sorting apparatus 1, FIG. 5A is an operation when the banknote P is the correct banknote P1, and FIG. The operation when P2 is shown.

  As shown in FIG. 5 (a), when a genuine note P1 whose rigidity is not deteriorated is sandwiched by the feed roller 3 and sent out, the leading end reaches the upstream end in the transport direction of the stage 5 with a distance L therebetween. Since the bending until this time is small, the front end portion of the correct ticket P1 is guided by the guide 4 and the stage 5, received by the receiving roller 6, and sent further downstream.

  On the other hand, as shown in FIG. 5 (b), when the slipped P2 having deteriorated rigidity is sandwiched between the feed rollers 3 and sent out, the leading end reaches the upstream end in the transport direction of the stage 5 separated by a distance L. Since the bending until the leading edge is large, the leading end portion of the damaged ticket P2 is sent out while hanging down without reaching the stage 5, and is dropped and accumulated in the recognition unit reject box 7 installed at the lower part of the stage 5.

  And the distance L between the clamping part of the banknote P of the feed roller 3 and the near side edge part of the stage 5, the feeding angle of the banknote P from the feeding roller 3, the clamping part of the feeding roller 3, and the upper surface of the stage 5 It is possible to arbitrarily set the sorting standard for the rigidity-deteriorated banknotes according to the banknote conveyance speed. Furthermore, if the feeding angle of the banknotes P from the feeding roller 3 is set downward, it is possible to perform sorting while performing higher speed conveyance using air resistance.

  As described above, according to the paper sheet sorting apparatus according to the first embodiment, it is possible to sort paper sheets with deteriorated rigidity with high accuracy and high speed by a simple mechanism.

Second Embodiment
FIG. 6 is a configuration diagram of a slip-sheet sorting device 1a constituting the paper sheet sorting device according to the second embodiment of the present invention. As shown in FIG. 6, in addition to the structure of said 1st Embodiment, two pairs of LED and a light receiving sensor are provided in the non-use ticket sorter 1a. Since the other components are the same as those in the first embodiment, the same reference numerals are given and duplicate descriptions are omitted.

  The pair of the LED 10 and the light receiving sensor 11 detects that the leading edge of the bill P has reached the optical path M connecting the two, and the pair of the LED 8 and the light receiving sensor 9 provided in the sky above the optical path M. Provided to initiate the deflection measurement. In response to a command from the control unit 13, light is emitted from the LED 10 in an initial state where no bill P is present on the optical path M, and the control unit 13 outputs an output that the light receiving sensor 11 outputs according to the amount of light received. Monitor the signal.

  Here, it is assumed that the bill P is sent out by the feed roller 3 and the leading end of the bill P reaches the optical path M as shown in FIG. At this time, since the light emitted from the LED 10 is blocked by the bill P and does not reach the light receiving sensor 11, the control unit 13 detects that the bill P has arrived from the output signal of the light receiving sensor 11. Therefore, as shown in FIG. 7B, the control unit 13 turns off the LED 10 and turns on the LED 8, and the light receiving sensor 9 outputs the amount of light received from the LED 8 and reflected on the banknote P. Capture the output signal.

  When the banknote P is a genuine note P1, as shown in FIG. 8 (a), since the deflection is small, the tip does not sag so much, and a relatively large amount of received light is observed by the light receiving sensor 9. On the other hand, when the banknote P is a non-performing bill P2, as shown in FIG. 8 (b), the leading end droops greatly due to large deflection, and only a small amount of reflected light reaches the light receiving sensor 9, so that the received light reception is observed. The amount is greatly reduced.

  The control unit 13 compares the value of the output signal acquired from the light receiving sensor 9 with a predetermined threshold value, and if the value of the output signal is larger than the threshold value, the banknote P is determined to be a genuine note P1, and the value of the output signal is the threshold value. If it is below, it will determine with the banknote P being the loss ticket P2.

  Next, as shown in the operation image of FIG. 9A, the control unit 13 determines that the banknote P is a genuine note P1, and uses a motor control mechanism (not shown) to feed the receiving roller 3 and the receiving roller 6. The rotation speed of both is increased to increase the conveyance speed of the correct ticket P1. On the other hand, when the control unit 13 determines that the banknote P is a damaged ticket P2, as shown in the operation image of FIG. 9B, the control unit 13 slows the rotation of the feed roller 3 to decrease the transport speed of the damaged ticket P2. The fall speed to the recognition unit reject box 7 is adjusted.

  As described above, according to the paper sheet sorting apparatus according to the second embodiment, the throughput of the apparatus can be improved by increasing the conveyance speed of the correct bills, and the falling speed of the recovered slips can be improved. It is possible to prevent damage to the damaged bills by lowering.

  In the above example, two pairs of LEDs and light receiving sensors are provided. However, the light receiving sensor 9 and the light receiving sensor 11 may be configured as one common light receiving sensor. It is good also as a structure which makes a light source one LED by using for the banknote position detection for the light from LED8 to move to. The sensor is not limited to an optical sensor, and may be another sensor having the same function.

<Third Embodiment>
FIG. 10 is a configuration diagram of a slippery sorting device 1b that constitutes the paper sheet sorting device according to the third embodiment of the present invention. As shown in FIGS. 10 (a) and 10 (b), in addition to the configuration of the second embodiment, a stage movement that moves the stage 5 back and forth along the bill conveyance direction is included in the damaged ticket sorting apparatus 1b. A stage moving motor 12 as means is additionally provided. Since the other components are the same as those in the second embodiment, the same reference numerals are given and duplicate descriptions are omitted.

  The stage moving motor 12 is controlled by the control unit 13 and moves the stage 5 to the upstream side in the transport direction as indicated by the broken line and the arrow in FIG. 10A, and the broken line and the arrow in FIG. As shown by, the stage 5 is moved downstream in the transport direction.

  It is preferable that the distance L1 with the holding portion of the feed roller 3 when the stage 5 moves most upstream in the transport direction is shorter than one half of the length of the banknote P, and the stage 5 is most downstream in the transport direction. It is preferable that the distance L2 with the holding part of the feed roller 3 when moved to the length of the banknote P is longer than the length of the banknote P.

  In the initial state where the bill P is not present on the optical path M, the control unit 13 moves the stage 5 to the middle between the most upstream side and the most downstream side in the bill conveyance direction. Other operations until the correctness of the banknote P is determined are the same as those in the second embodiment.

  And the control part 13 controls the stage moving motor 12, when it determines with the banknote P being the correct bill P1, and the stage 5 is the most in a banknote conveyance direction so that the operation | movement image may be shown to Fig.11 (a). Move upstream. Thereby, when the rotation speed of the feed roller 3 and the receiving roller 6 is increased and the conveyance speed is increased, the correct ticket P1 can be prevented from being damaged due to the collision with the stage 5, and the correct delivery of the correct ticket P1 can be more reliably performed. Can be done.

  On the other hand, as shown in the operation image of FIG. 11B, the control unit 13 controls the stage moving motor 12 and determines that the stage 5 is the most in the banknote transport direction when the banknote P is determined to be a non-payment P2. Move downstream. Thereby, when the rotation speed of the feed roller 3 is reduced to reduce the conveyance speed of the damaged ticket P2, damage to the damaged ticket P2 due to the collision with the stage 5 can be prevented.

  As described above, according to the paper sheet sorting apparatus according to the third embodiment, it is possible to prevent the paper sheet from being damaged by reducing the collision of the paper sheet with the stage unit. In addition, when the paper quality differs depending on the denomination or the size in the transport direction differs, it is preferable to change the moving range of the stage unit according to the denomination.

  Although description of the form which implements this invention is finished above, this invention is applicable not only to an automatic transaction apparatus but the cash exchange apparatus, vending machine, etc. which handle a banknote similarly. The object to be handled is not limited to banknotes, and may be other paper sheets that are returned to the market. Further, the present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the gist of the present invention.
