Japanese Patent Laid-Open No. 2002-19985

  In order to feed banknotes one by one at the time of the feeding operation, it is preferable that the ends of the plurality of banknotes stored in the stacking unit (ends on the front side in the feeding direction) are aligned. However, in the case where the size varies greatly depending on the bill type, such as overseas bills, the mechanism for aligning the end portions of the bills may not function depending on the size. For example, when the mechanism for aligning the end portions has a structure for attracting banknotes, the structure for attracting banknotes does not reach a banknote having a small size. Thus, when the edge part of a banknote is not aligned, there exists a possibility that the feeding mistakes, such as misfeed (multiple sheet feeding) and paper jam (clogging), may occur at the time of banknote feeding.

  In one aspect, an object of the present invention is to provide a paper sheet feeding device capable of suppressing the occurrence of a paper sheet feeding error.

  In one aspect, the paper sheet feeding device blows a uniaxial wind in a horizontal plane to the paper sheet that has been transported to a predetermined position by the transport unit and has fallen from the predetermined position. The flutter vibration is generated in the blower unit, the air blowing unit that moves the paper sheets along the uniaxial direction, the drawing unit that draws the paper sheets that have fallen from the predetermined position, and the drawing unit. A wall portion against which the one axial end of the paper sheet is abutted; and a feeding portion for feeding out the paper sheets abutted against the wall portion one by one.

  Occurrence of paper sheet feeding mistakes can be suppressed.

It is a figure which shows the state in which the + Y edge part of the banknote was gathered by the effect | action of a ventilation part. It is a graph for demonstrating the continuous variable control of the wind speed of a ventilation part.

  Hereinafter, an embodiment of an ATM (Automated Teller Machine) will be described in detail with reference to FIGS.

  FIG. 1 schematically shows the configuration of an ATM 100 according to an embodiment. The ATM 100 is a so-called reflux type ATM, in which banknotes received by a customer are stored inside the apparatus, and when there is a request from another customer, the banknote stored in the apparatus in response to the request. This is a device that executes a payout process using the.

  As illustrated in FIG. 1, the ATM 100 includes a housing 10, a banknote transport belt 12 as a transport unit, a feeding device 14, a discrimination unit 16, and a denomination sorting unit 18 provided in the housing 10. And banknote type safes 20 </ b> A to 20 </ b> C and a banknote transport mechanism 22. In addition, a control unit 30, a power supply unit 32, and the like are provided in the casing 10 of the ATM 100. In this embodiment, the direction orthogonal to the paper surface of FIG. 1 is defined as the X-axis direction, the horizontal direction in the paper surface is defined as the Y-axis direction, and the vertical direction in the paper surface is defined as the Z-axis direction. FIG. 2 is a block diagram showing the control system of the ATM 100.

  A bill insertion slot 10 a is provided on the front side (+ Y side) of the housing 10. An opening / closing door 11 is provided at the bill insertion slot 10a. The door 11 is opened and closed by the bill slot opening / closing drive motor 52 shown in FIG. The control unit 30 detects the open / closed state of the open / close door 11 using a sensor S1 provided in the vicinity of the bill insertion slot 10a of the housing 10. The sensor S1 may be any sensor that can detect opening / closing of the open / close door 11 (whether it is fully open or fully closed). For example, an optical sensor, a contact sensor, an image sensor, or the like can be employed. Moreover, the control part 30 controls the closing operation of the door 11 based on the detection result of sensor S2 provided in the banknote slot 10a vicinity. The sensor S2 may be any sensor that can detect that a bill has been inserted into the bill insertion slot 10a. For example, an optical sensor, a contact sensor, an image sensor, or the like can be employed.

  The banknote transport belt 12 rotates a banknote inserted into the banknote insertion slot 10a by, for example, a counterclockwise rotation operation of FIG. 1 in a predetermined uniaxial direction (Y-axis direction, more specifically from + Y direction to -Y direction). ). The banknote transport belt 12 is driven by a banknote transport belt drive motor 54 under the control of the control unit 30. The control unit 30 starts to drive the banknote transport belt drive motor 54 based on the detection result of the sensor S1 (detection result indicating that the open / close door 11 is changed from the open state to the closed state). Moreover, the control part 30 stops the drive of the banknote conveyance belt drive motor 54 based on the detection result of sensor S3 mentioned later.

  The feeding device 14 has a function as a stacking unit that stores banknotes conveyed on the banknote transport belt 12, and also has a function of feeding banknotes one by one and carrying them out to the discrimination unit 16. The specific configuration of the feeding device 14 will be described later.

  A sensor S3 is provided in the vicinity (upstream side) of the feeding device 14. The sensor S3 may be any sensor that can detect whether or not a bill has been transported by the bill transport belt 12, and for example, an optical sensor or an image sensor can be employed. A sensor S4 is provided on the + Y side (downstream side) of the feeding device 14. The sensor S4 may be any sensor that can detect whether or not a bill is being paid out from the payout device 14, and for example, an optical sensor or an image sensor can be employed. The detection results of the sensors S3 and S4 are transmitted to the control unit 30.

  The discrimination unit 16 discriminates each banknote carried out from the feeding device 14 and transmits the discrimination result to the control unit 30. The control unit 30 controls the denomination sorting unit 18 based on the discrimination result, and sorts the banknotes that have passed through the discrimination unit 16 into one of the banknote type safes 20A to 20C. Thereby, the banknote with the same face value is stored in each of the banknote type safes 20A to 20C. In FIG. 1, three banknote-type safes are illustrated, but the number of banknote-type safes may be four or more according to the number of banknotes, or two or less. Good.

  The banknote transport mechanism 22 supplies the banknotes transported from the banknote type safes 20 </ b> A to 20 </ b> C onto the banknote transport belt 12 under the control of the control unit 30 when there is a payout request from the customer. The banknote transport mechanism 22 is driven by the banknote transport mechanism drive motor 62 of FIG. In addition, the control part 30 rotates the banknote conveyance belt 12 in the clockwise direction of FIG. 1 according to the drive timing of the banknote conveyance mechanism 22, for example. Thereby, a banknote is conveyed to the banknote insertion slot 10a.

  Next, a specific configuration and the like of the feeding device 14 will be described based on FIGS.

  FIG. 3 is a diagram schematically showing the feeding device 14. As shown in FIG. 3, the feeding device 14 has a space 85 surrounded by a front wall 82, a rear wall 84, an upper wall 81, and a bottom wall 83 as wall portions. In this space 85, the bills conveyed by the bill conveyance belt 12 are accumulated (stored). The feeding device 14 includes a rubber impeller 70, a pick roller 72, a feed roller 74, a separation roller 76, a pressing plate 86, and a blower 90. 4 is a perspective view showing the pick roller 72, the feed roller 74, and the separate roller 76 taken out.

  The front wall 82 and the rear wall 84 are walls formed using a net-like material (for example, a wire net). The front wall 82 is provided with a slit or the like so as not to mechanically interfere with the rubber impeller 70. A blower 90 is provided on the −Y side of the rear wall 84. As described above, since the rear wall 84 and the front wall 82 are formed using a net-like material, the wind blown from the blower 90 passes through the space 85.

  Although not shown in FIG. 4, a plurality of (for example, four) rubber impellers 70 are provided along the vertical direction in FIG. The rubber impeller 70 includes a shaft member that rotates about the X-axis direction of FIG. 3 and a plurality (eight in FIG. 3) of rubber blades that are radially attached to the shaft member. The rubber impeller 70 rotates counterclockwise around the axis of the shaft member via the rubber impeller drive motor 56 under the control of the control unit 30. The rubber impeller 70 has a function of moving the banknote conveyed along the arrow A in FIG. 3 to a predetermined position (see reference numeral 200A) in the space 85 by such a rotation operation. Further, the rubber impeller 70 has a function of knocking down a banknote falling in the −Z direction from a predetermined position (200A) and drawing the hit banknote toward the front wall 82 side. In addition, since the edge part of the banknote attracted | pulled by this rubber impeller 70 is abutted on the -Y side surface of the front wall 82, the edge part of each attracted banknote comes to be aligned. In addition, in this embodiment, the function of the conveyance part which conveys a banknote to the predetermined position 200A including the banknote conveyance belt 12 and the rubber impeller 70 is implement | achieved.

  The pick roller 72 is a roller for paying out bills accumulated (stored) in the space 85 to the discrimination unit 16 side. In the present embodiment, as shown in FIG. 4, two pick rollers 72 are provided at a predetermined interval in the X-axis direction. The pick roller 72 rotates in the clockwise direction of FIG. 3 via the banknote feeding roller drive motor 58 shown in FIG. 2 under the control of the control unit 30. Note that since the banknotes are stored in the space 85 with the X-axis direction as the longitudinal direction and the Y-axis direction as the short direction, the pick roller 72 pays out the banknotes in the short direction.

  The feed roller 74 is a roller that conveys the banknotes fed by the pick roller 72 toward the discrimination unit 16. In this embodiment, as shown in FIG. 4, five feed rollers 74 are provided at predetermined intervals in the X-axis direction. The pick roller 72 and the feed roller 74 are provided with a high friction portion (for example, a rubber portion) for temporarily applying a conveying force to the bill, and the remaining portion is a low friction portion. The pick roller 72 and the feed roller 74 are connected by a belt or the like. Thereby, the feed roller 74 rotates in the clockwise direction of FIG. 3 in synchronization with the rotation of the pick roller 72 (the rotation of the bill feeding roller drive motor 58).

  The separate roller 76 is a roller for preventing multiple payout of banknotes (takeout of banknotes above the second one from the bottom, which occurs when the first banknote is drawn from the bottom). In the present embodiment, four separate rollers 76 are provided at predetermined intervals in the X-axis direction, as shown in FIG. Since the height (Z position) of the lower end portion of the separation roller 76 is set to a position lower than the upper end portion of the feed roller 74, the separation roller 76 and the feed roller 74 are related to the vertical direction (Z-axis direction). It can be said that they are arranged in an overlapping manner. Although not shown in FIG. 3, a resin-made building slider 69 is provided on the −Y side of the separation roller 76 as shown in FIG. As shown in FIG. 4, a rubber pressure roller 67 is provided on the upper side of the feed roller 74 located at the center of the five feed rollers 74. In this embodiment, the pick roller 72, the feed roller 74, and the separation roller 76 are included and function as a feeding unit for feeding banknotes one by one.

  Returning to FIG. 3, the presser plate 86 is moved downward (−Z direction) by the presser plate driving unit 64 of FIG. 2 after all the bills inserted from the bill insertion slot 10 a are accumulated (stored) in the space 85. Driven. Thereby, the banknote with which the press board 86 was integrated | stacked (stored) in the space 85 can be pressurized from the top.

  The blower 90 is a cross flow fan, for example, and uses the rotational force of the blower fan drive motor 60 shown in FIG. 2 along the Y-axis direction from the back side (−Y side) of the rear wall 84 toward the space 85. Blow the wind in the right direction. The controller 30 controls the operation of the blower fan drive motor 60 (wind speed of the cross flow fan). A specific method for controlling the blower fan drive motor 60 will be described later.

  Next, the processing until the feeding device 14 carries out banknotes inserted from the user (customer) of the ATM 100 toward the discrimination unit 16 will be described in detail with reference to other drawings as appropriate along the flowchart of FIG. explain.

  Assuming that the processing of FIG. 5 is executed, it is assumed that a user (customer) of the ATM 100 has input an instruction for depositing via an input unit (not shown).

  In the process of FIG. 5, first, in step S <b> 10, the control unit 30 drives the bill insertion slot opening / closing drive motor 52 to open the opening / closing door 11 (the bill insertion slot 10 a).

  Next, in step S12, the control unit 30 stands by until the sensor S1 is turned on (that is, the door 11 is fully opened). The control unit 30 proceeds to step S14 when the open / close door 11 is fully opened.

  If transfering it to step S14, the control part 30 will start the rotational drive of the ventilation fan drive motor 60. FIG. That is, the control unit 30 starts blowing out the wind from the air blowing unit 90. Next, in step S16, the control unit 30 stands by until the sensor S2 is turned on, that is, until a bill is inserted into the bill insertion slot 10a. When a bill is inserted into the bill insertion slot 10a by the user, the control unit 30 proceeds to step S18.

  If transfering it to step S18, the control part 30 will drive the banknote slot opening / closing drive motor 52, after waiting for several seconds. Thereby, the opening / closing door 11 (banknote insertion slot 10a) transitions from the open state to the closed state. Next, in step S20, the control unit 30 stands by until the sensor S1 is turned off, that is, until the door 11 is fully closed. The control unit 30 proceeds to step S22 when the open / close door 11 is fully closed.

  If transfering it to step S22, the control part 30 will start rotation of the banknote conveyance belt drive motor 54 and the rubber impeller drive motor 56. FIG. Next, in step S24, the control unit 30 stands by until the sensor S3 no longer detects a bill for a specified time. That is, it waits until a banknote is no longer sent from the banknote conveyance belt 12 side.

  By the way, the control unit 30 variably controls the wind speed so that the wind from the air blowing unit 90 generates flutter on the banknote, thereby flapping the banknote as shown in FIG. It is moved in the direction of 82.

  Here, when the width of the banknote in the short direction (Y-axis direction) is not so different depending on the type of bill (for example, in the case of a Japanese banknote), the blower 90 is not provided as shown in FIG. However, by rotating the rubber impeller 70, each banknote can be knocked down and pulled in the direction of the front wall 82. This is because the width of the banknote in the short direction is not different, so that the rubber blade of the rubber impeller 70 reaches the banknote even in the banknote having the smallest width. Thus, regardless of the bill type, the rubber impeller 70 pulls in the bills, so that the + Y side ends of the bills can be aligned as shown in FIG. 7B. On the other hand, when the width in the short direction (Y-axis direction) varies greatly depending on the type of the bill, such as euro bills (62 to 82 mm in the case of euro bills), on the other hand, as shown in FIG. If the width of the direction is small, the rubber impeller 70 may not reach the banknote, and the banknote may hit the rear wall 84 and fall freely. In this case, as shown in FIG.8 (b), there exists a possibility that the + Y side edge part of a banknote may not align.

  In contrast, in the present embodiment, as described above, the air blowing unit 90 that sends the wind from the rear wall 84 side toward the front wall 82 side is provided, and the control unit 30 causes the wind from the air blowing unit 90 to flutter on the banknote. The wind speed is variably controlled to generate Therefore, as shown in FIG. 9, even if the width in the short direction of the banknotes stored in the space 85 varies greatly depending on the ticket type, the rubber impeller 70 can draw the banknotes. Thereby, it becomes possible to arrange | equalize + Y edge part of each banknote.

  Here, the wind speed that generates flutter on the banknote can be calculated from the mass, rigidity, attenuation, etc. of the banknote, but the rigidity of the banknote differs between the circulation ticket and the government seal. For this reason, the range of the wind speed is determined by conducting an experiment for determining the wind speed at which flutter is actually generated using the circulation ticket having the smallest rigidity and the official seal (the banknote having the greatest rigidity). preferable.

More specifically, it is the heaviest ticket type among the samples of banknotes (a plurality (n) types of banknotes if there are a plurality of types) of which the tip of the rubber blade of the rubber impeller 70 does not reach and the width in the short direction is narrow. In addition, the wind speed at which flutter is generated in the softest banknote is obtained by experiment. In addition, the wind speed at which flutter occurs in the lightest ticket type and the hardest official seal among the samples is determined by experiment. Then, the control unit 30, the minimum was sought wind (two values) Flow rate v _0, the maximum flow velocity v _1, as shown in FIG. 10, periodically continuously variable controlled by cycle 3t _1. Note that the length of t ₁ is defined by the following equation (1) based on the number of banknotes that can be deposited at one time (maximum depositing number Ma) and the number of banknotes (Mb) drawn out from the space 85 per second.
t ₁ = Ma / (Mb / (1 / n)) (1)

  The above equation (1) takes into consideration the time required for the flutter to be generated and moved on the banknote, obtained by experiment or experience.

By adopting t ₁ represented by the above formula (1), the maximum deposit number Ma is 50, the feeding speed Mb is 6 sheets / second, and the number of ticket types n that the tip of the rubber blade of the rubber impeller 70 does not reach is In the case of 3, t ₁ is approximately 2.7 seconds. As described above, the control unit 30 continuously and variably controls the air blowing unit 90 as shown in FIG.

Returning to FIG. 5, if the determination in step S <b> 24 is affirmed, that is, if all the bills inserted into the bill insertion slot 10 a are stored in the space 85, the process proceeds to step S <b> 26. If transfering it to step S26, the control part 30 will stop operation | movement of the banknote conveyance belt drive motor 54. FIG. Next, in step S28, the control unit 30 stops the blower fan drive motor 60 after a specified time. The specified time is assumed to be, for example, 1 cycle = 3t ₁ described above. Next, in step S30, the control unit 30 stops the rubber impeller drive motor 56. Note that the processing of steps S26 to S30 may be performed simultaneously or in any order.

  Next, in step S <b> 32, the control unit 30 starts to rotate the bill feeding roller drive motor 58. Thereby, since the pick roller 72 and the feed roller 74 are rotated, the banknotes stored in the space 85 are conveyed to the discrimination unit 16 one by one from the bottom. Here, since the banknotes stored in the space 85 are in a state in which the + Y side ends are aligned regardless of the type of the banknote, it is possible to suppress the multiple payout of banknotes and the occurrence of paper jam as much as possible. it can.

  Next, in step S34, the control unit 30 stands by until the sensor S4 no longer detects a bill for a specified time. That is, the control unit 30 waits until all the banknotes in the space 85 are conveyed to the discrimination unit 16. In this case, the control unit 30 proceeds to step S36 when the sensor S4 stops detecting a bill for a predetermined time or longer.

  If transfering it to step S36, the control part 30 will stop the drive of the banknote feeding roller drive motor 58. FIG. Thereby, the process of FIG. 5 is completed. In addition, after the process of FIG. 5 is complete | finished, although a process is performed in the money type distribution part 18, banknote classification safe 20A-20C, and the banknote conveyance mechanism 22, since the process of these each part is the same as the past, Description is omitted.

  As described above in detail, according to the present embodiment, the feeding device 14 is transported to the predetermined position (200A) by the banknote transport belt 12 and the rubber impeller 70, and is applied to the banknotes that have fallen from the predetermined position (200A). On the other hand, by blowing wind in the Y-axis direction and causing flutter vibration on the banknote, the air blowing unit 90 that moves the banknote along the Y-axis direction, and the rubber blade that draws the banknote that has fallen from the predetermined position (200A) A front wall 82 against which one end (+ Y end) in the Y-axis direction of the banknote attracted by the wheel 70 and the rubber impeller 70 is abutted, and a pick roller for feeding out the banknote abutted against the front wall 82 one by one 72. Thereby, in this embodiment, since the difference of the width | variety (width | variety of a transversal direction) regarding the Y-axis direction of a banknote is large for every bill type, the rubber impeller 70 is drawn in the banknote which falls freely from predetermined position 200A. Even if there is no banknote, the banknote can be moved in the + Y direction by the wind from the blower 90. Thereby, the banknote which cannot be pulled near by the rubber impeller 70 can be eliminated as much as possible. As a result, the + Y end portions of the banknotes can be aligned by abutting against the front wall 82, so that it is possible to suppress the occurrence of multiple feeding and paper jam when the pick roller 72 is fed.

  Moreover, in this embodiment, the control part 30 variably controls the speed of the wind sprayed from the ventilation part 90 based on the rigidity of a banknote. Thereby, even if it is a case where a banknote of various rigidity is thrown in in ATM100, based on the rigidity of a banknote, the wind speed can be variably controlled in the range which a flutter vibration tends to produce in a banknote. Therefore, it is possible to effectively move the banknote in the + Y direction.

  In the present embodiment, the front wall 82 has a structure (for example, a net-like structure) through which the wind blown from the blower 90 passes, so that the banknotes are efficiently moved in the + Y direction by the wind from the blower 90. Can be moved.

Further, in the present embodiment, the air blowing is continued for a specified time (for example, 3t ₁ ) after the sensor S3 no longer detects the banknote. Thereby, the banknote which is falling freely in the space 85 can be reliably moved in the + Y direction. Since the time 3t ₁ is shorter than the time for processing the bills inserted into the ATM 100 (up to about 8 seconds), there is almost no influence on the user's ATM processing waiting time.

  In the above-described embodiment, the blowing range in the X-axis direction of the blowing unit 90 is made the same as the maximum value in the width in the longitudinal direction (X-axis direction) among the types of bills that may be thrown into the ATM 100. be able to. Thereby, the wind from the ventilation part 90 can be efficiently applied to a banknote.

  In addition, although the control part 30 demonstrated the case where the control of the wind speed like FIG. 10 was performed in the said embodiment, it is not restricted to this. For example, the wind speed may be variably controlled so as to change in a sine wave shape, or other variable control may be performed.

  Moreover, although the said embodiment demonstrated the case where the banknote conveyed by the -Y direction with the banknote conveyance belt 12 was drawn | fed out from the delivery apparatus 14 to + Y direction, it is not restricted to this. For example, the ATM 100 may have a structure in which a banknote transported in the −Y direction by the banknote transport belt 12 is fed out from the feeding device 14 in the −Y direction. In this case, a feeding device (a device in which the wind from the sending unit is blown from the + Y direction to the −Y direction) that is the left-right reversal of the feeding device 14 of FIG. 1 may be provided in the ATM 100.

  In the above-described embodiment, the case where the paper sheet feeding device is applied to the ATM 100 has been described. However, the present invention is not limited to this, and the paper feeding device as in the above-described embodiment is not limited to this. 14 may be applied.

  The above-described embodiment is an example of a preferred embodiment of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the present invention.
