Is fitted to the outer periphery of the rotary shaft 4 so as to be adjacent to the second impeller 2 at the position, and is fixed to the rotary shaft 4 with a screw or the like (not shown), and further for rotating the second impeller 2. The pin 25 is fixed to the rotary shaft 4 so as to sandwich the second impeller 2 between the holding member 3 and the second impeller 2 is rotatable with respect to the rotary shaft 4.

  The first impeller 1 and the second impeller 2 are arranged at regular intervals so that a plurality of blades 1a and 2a having elasticity (flexibility) form a radial shape in a range of about half on the outer circumference. As shown in FIG. 3, the second impeller 2 is provided with a protrusion 2b and a protrusion 2c that abut on and engage with the pin 25 on the surface facing the first impeller 1 as shown in FIG. They are provided at intervals of approximately 180 degrees.

  The protrusions 2b and the pins 25 serve as driving means for rotating the second impeller 2 together with the rotation shaft.

  2d is a semicircular flange portion formed at the same position as the blade 2a at the outer peripheral portion on the end face side of the second impeller 2, and the diameter thereof is smaller than the outer periphery of the auxiliary roller 27 described later when viewed from the axial direction. So that the lengths overlap each other.

  In the figure, the number of the blades 1a and 2a of the first impeller 1 and the second impeller 2 is shown as four, but this is not a limitation.

  As shown in FIG. 4, the pressing member 3 is formed in a short cylindrical shape, and has a substantially semicircular flange on the outer peripheral portion on the end face side in contact with the second impeller 2 and having substantially the same diameter as an outer diameter of a reverse roller described later. A portion 3 a is formed, and the pressing member 3 is fixed to the rotating shaft 4 so that the flange portion 3 a is located at the same position as the blade 1 a of the first impeller 1 on the outer periphery of the rotating shaft 4.

  In addition, since the flange part 3a may be formed in the rotating shaft 4, the presser member 3 can also be abbreviate | omitted in that case.

  The spring 26 is fitted on the outer periphery of the rotating shaft between the first impeller 1 and the second impeller 2, and one end of the spring 26 is inserted and fixed in a lateral hole provided in the first impeller 1; The other end is inserted and fixed in a lateral hole provided in the protrusion 2 b of the second impeller 2, and generates a predetermined urging force against the second impeller 2.

  Reference numeral 5 denotes a drive gear that transmits rotation of a motor (drive source) (not shown) to the rotary shaft 4, and this drive gear 5 is attached to the rotary shaft 4 via a one-way clutch 6. Only the rotation is transmitted to the rotating shaft 4.

  Reference numeral 7 denotes a positioning member fixed to the rotating shaft 4, and has a detected portion 7 a that is partially protruded from the outer peripheral portion.

  Reference numeral 8 denotes a position detection sensor for optically detecting the detected portion 7a. When the detected portion 7a enters between the light emitting element and the light receiving element, the detected portion 7a is detected. The stop position of the first impeller 1 is controlled based on the detection output of the position detection sensor 8.

  FIG. 5 is a side view showing the operation of the second impeller 2 configured as described above.

  FIG. 5A shows a state in which the rotating shaft 4 is stopped. In this state, the second impeller 2 is rotated in the clockwise direction by the biasing force in the direction of arrow A by the spring 26, and the second impeller 2 The protrusion 2c stops at a position where it comes into contact with the pin 25 fixed to the rotating shaft 4.

  From this state, when the rotational force of the drive gear 5 (see FIG. 2) driven by a motor (not shown) is transmitted to the rotary shaft 4 via the one-way clutch 6 (see FIG. 2), the rotary shaft 4 is indicated by an arrow B. If the blade 2a is not subjected to a load at this time, the second impeller 2 is maintained while the projection 2c is in contact with the pin 25 as shown in FIG. Rotates following the rotation of the rotating shaft 4.

  Then, as the rotating shaft 4 and the second impeller 2 continue to rotate, the blade 2a on the tip side in the rotation direction comes into contact with a medium (not shown) (such as a banknote described later), as shown in FIG. Upon receiving the load F, the rotation of the second impeller 2 stops and only the rotating shaft 4 rotates, so that the pin 25 rotating integrally with the rotating shaft 4 moves away from the protrusion 2c.

  However, in this case, the load due to the blade 2 a coming into contact with the medium is larger than the urging force of the spring 26. In other words, the elastic force (waist strength) of the blade 2 a needs to be stronger than the urging force of the spring 26.

  Further, when only the rotating shaft 4 rotates, the pin 25 eventually hits the protrusion 2b of the second impeller 2, and thereby a rotational force larger than the load F applied to the blade 2a is applied to the second impeller 2. The second impeller 2 rotates in the clockwise direction together with the rotating shaft 4.

  FIG. 6 is a side view showing the operation of the impeller mechanism configured as described above.

  FIG. 6A shows a state in which the rotating shaft 4 is stopped. In this state, the blades 1 a and 2 a of the first impeller 1 and the second impeller 2 are located in a range approximately half of the outer periphery of the rotating shaft 4. In addition, as described with reference to FIG. 3, the projection 2 c of the second impeller 2 is in contact with the pin 25 by the biasing force of the spring 26.

  From this state, when the rotational force of the drive gear 5 (see FIG. 2) driven by a motor (not shown) is transmitted to the rotary shaft 4 via the one-way clutch 6 (see FIG. 2), the rotary shaft 4 rotates in the clockwise direction. As shown in FIG. 6B, the first impeller 1 rotates integrally with the rotating shaft 4.

  At this time, the second impeller 2 rotates clockwise and follows the first impeller 1 by the urging force of the spring 26 as described in FIG.

  By this rotation, the blades 1a and 2a of the first impeller 1 and the second impeller 2 move, and when the first impeller 1 and the second impeller 2 rotate by a predetermined angle, FIG. As shown in c), the blades 1 a and 2 a come into contact with the banknote 10 accumulated in the middle of the rotation path, and thus the blades 1 a and 2 a receive a contact load from the banknote 10.

  Here, as described with reference to FIG. 5, the second impeller 2 stops rotating when the blade 2 a receives a load, and only the first impeller 1 fixed to the rotating shaft 4 has the rotating shaft 4. And the blade 1a of the first impeller 1 bends and passes through the contact position with the banknote 10.

  At this time, the pin 25 fixed to the rotating shaft 4 also moves away from the protrusion 2c of the second impeller 2.

  Then, the first impeller 1 further rotates together with the rotating shaft 4, and the blade 1 a of the first impeller 1 and the second impeller 2 when the pin 25 hits the protrusion 2 b of the second impeller 2. 2a is in a state of expanding radially around the entire circumference of the rotating shaft 4, and further rotating force is applied to the second impeller 2 by the pins 25 and the protrusions 2b by rotating the rotating shaft. The wheel 2 rotates together with the rotating shaft 4 and the first impeller 1 in the clockwise direction.

  Due to this rotation, the blade 2a of the second impeller 2 that is in contact with the banknote 10 bends and passes through the contact position with the banknote 10, and thereafter, the rotating shaft 4, the first impeller 1, and the second impeller. According to the rotation of 2, the operation of passing through the contact position is repeated so that the blades 1a and 2a strike the banknote 10 as shown in FIG.

  The rotation of the first impeller 1 can be stopped when the detected portion 7 a of the positioning member 7 fixed to the rotating shaft 4 is detected by the position detection sensor 8.

  The rotation is stopped by stopping the rotation of the motor. At this time, the first impeller 1 is controlled so that all the blades 1 a are not in contact with the banknote 10.

  After the rotation of the first impeller 1 is stopped, as shown in FIG. 6E, when the bill 10 is lowered so that the second impeller 2 does not come into contact with the blade 2a, the second impeller 2 is 4 (e) is rotated clockwise as shown in FIG. 6 (f) by the urging force of the spring 26, so that the protrusion 2c comes into contact with the pin 25 and stops. ) To return to the same state.

  In the operation of such an impeller mechanism, the pressing member 3 has the flange portion 3a provided over the outer periphery of the outer peripheral portion at the same position as the blade 1a of the first impeller 1 on the outer periphery of the rotary shaft 4 as described above. Therefore, it rotates integrally with the blade 1a.

And 2a so that it can be drawn.

  The first and second impellers 1 and 2 disposed between the reverse rollers 17 are arranged at a predetermined distance from a position corresponding to the center in the longitudinal direction of the bills being conveyed, that is, from the center between the reverse rollers 17. One impeller 1 is arranged on the right side and the second impeller 2 is arranged on the left side, so that the central part of the bill can be hit by both impellers 1 and 2.

  The arrangement and the number of the impellers 1 and 2 and the reverse roller 17 are not limited to this.

  The operation of the above configuration will be described.

  Note that the operation of each unit described below is controlled by a control unit (not shown) based on a program (software) stored in a storage unit (not shown).

  First, when the banknote 10 is fed, the first impeller 1 is stopped at the position where the detected portion 7a of the positioning member 7 fixed to the rotating shaft 4 is detected by the position detection sensor 8, and the first blade The blades 1a and 2a of the wheel 1 and the second impeller 2 and the flange portion 3a of the pressing member 3 are positioned in a substantially half range of the outer periphery of the rotating shaft 4 as shown in FIG. Evacuated to avoid getting inside.

  In this state, the stage 12 is raised, the uppermost banknote 10 on the stage 12 is brought into contact with the picker roller 14, and then the feed roller 13 is rotated clockwise by a motor (not shown). The rotation is transmitted to the picker roller 14 by the drive belt 16 and the picker roller 14 rotates in the clockwise direction, so that the bill 10 is fed out from the bill storage unit 11 and sent to the feed roller 13 side.

  At this time, the rotation of the motor is not transmitted by the one-way clutch 6 to the rotary shaft 4 to which the first impeller 1, the second impeller 2 and the reverse roller 17 are attached. The impeller 2 and the reverse roller 17 of the first impeller 1 and the second impeller 2 are not rotated, so that the blades 1a and 2a of the first impeller 1 and the second impeller 2 and the flange portion 3a of the pressing member 3 are kept in the retracted state.

  The banknote 10 sent to the feed roller 13 side is sandwiched between the feed roller 13 and the stopped reverse roller 17, and sent to the conveyance path 18 by the rotation of the feed roller 13, and then between the feed roller 13 and the pressure roller 28. And is transported by transport means (not shown).

  At the time of banknote accumulation, if the stage 12 is put on standby at a position where the uppermost banknote 10 is detected by the upper surface detection sensor 21 and the rotating shaft 22 is rotated counterclockwise by a motor (not shown), the stage 12 is fixed to the rotating shaft 22. The feed roller 13 and the auxiliary roller 27 are also rotated in the counterclockwise direction.

  At this time, the rotation of the motor is transmitted to the rotating shaft 4 to which the first impeller 1, the second impeller 2 and the reverse roller 17 are attached, whereby the first impeller 1 and the reverse roller 17 rotate clockwise. The second impeller 2 also rotates in the clockwise direction as described in FIG.

  Then, as described with reference to FIG. 6, when the blades 1 a and 2 a of the first impeller 1 and the second impeller 2 come into contact with the bill 10 and the rotation of the second impeller 2 stops, Only the impeller 1 continues to rotate, and when the pin 25 fixed to the rotating shaft 4 hits the protrusion 2b of the second impeller 2, the first impeller 1 and the blade 1a of the second impeller 2 2a expands radially over the entire circumference of the rotating shaft 4, and the second impeller 2 rotates together with the first impeller 1 as shown in FIG. 6B.

  When the banknote 10 is transported through the transport path 18 in this state, the transported banknote 10 passes between the feed roller 13 and the pressure roller 28 and is sandwiched between the feed roller 13 and the reverse roller 17. The paper is fed into the bill storage unit 11 by the rotation of the reverse roller 17.

  At this time, the wrinkles of the banknote 10 are as shown in FIG. That is, when the blade 2 a and the flange portion 2 d of the second impeller 2 are directed downward, the flange portion 3 a of the pressing member 3 is directed upward and overlaps the auxiliary roller 27. Since this flange portion 3a is outside the auxiliary roller 27, when the bill 10 is sandwiched between the feed roller 13 and the reverse roller 17 when the flange portion 3a of the pressing member 3 is facing upward, both longitudinal ends of the bill 10 are It is pushed up by the flange portion 3 a of the pressing member 3.

  Then, as the rotating shaft 4 continues to rotate, the blade 1a of the first impeller 1 and the flange portion 3a of the pressing member 3 face downward, but instead, as shown in FIG. The impeller 2 is directed upward, and the flange portion 2d formed in the same phase as the second impeller 2 is also directed upward and overlaps the auxiliary roller 27. Since the flange portion 2d is outside the auxiliary roller 27, when the second impeller 2 is directed upward, both longitudinal ends of the banknote 10 are pushed up by the flange portion 2d.

  As described above, the both ends in the longitudinal direction of the banknote 10 are connected to the flange part 2d of the second impeller 2 or the pressing member 3 while the banknote 10 is fed into the banknote storage part 11 by the rotation of the feed roller 13 and the reverse roller 17. It is always pushed up by the flange part 3a and discharged into the banknote storage part 11 with a firmness in the short direction of the banknote.

  The banknote 10 fed into the banknote storage unit 11 collides with the bill stopper 20 and is stopped and dropped. At this time, the rear end of the banknote 10 is the first impeller 1 as shown in FIG. The blades 1a and 2a of the second impeller 2 are struck and pressed onto the banknote 10 on the stage 12, and are aligned so as not to prevent the subsequent banknotes 10 from being stacked.

  Here, FIG. 8 is explanatory drawing which shows the 1st impeller and 2nd impeller which press the center part of a banknote, (a) is a mode when the blade | wing of a 1st impeller pressed the banknote, (B) has shown the mode when the 2nd impeller pressed the banknote.

  Moreover, the left and right of the center in the longitudinal direction of the uppermost banknote 10 accumulated by the first impeller 1 and the second impeller 2 provided in the central portion of the rotating shaft 4 are alternately pressed, that is, the first After the blade 1a of the impeller 1 presses the right side of the center of the bill 10 in the longitudinal direction and the blade 1a is separated, the blade 2a of the second impeller 2 presses the left side of the center of the bill 10 in the longitudinal direction. When the is separated, the blade 1a of the first impeller 1 presses the bill again.

  Therefore, when the first impeller 1 in FIG. 8A is rotated, when the blade 1a hits the left side of the peak of the bill shape indicated by the dotted line as shown in the direction of arrow a, the bill 10 is moved to the arrow. It shifts to the left in the a ′ direction, that is, the banknote longitudinal direction, but then the second impeller 2 in FIG. 8B rotates, and as shown in the arrow b direction, the peak 2 of the bill is indicated by the dotted line. The banknote 10 is shifted to the left in the arrow b ′ direction, that is, the right side of the banknote longitudinal direction by striking the right side of the banknote 10 so that the position of the banknote 10 is not biased to one side.

  When the accumulation ends, the motor is stopped so that the first impeller 1 stops at the position where the detected portion 7a of the positioning member 7 fixed to the rotating shaft 4 is detected by the position detection sensor 8.

  As a result, as described with reference to FIG. 6, the second impeller 2 rotates in the clockwise direction by the urging force of the spring 26, and the blades 1 a and 2 a of the first impeller 1 and the second impeller 2 and the presser The flange portion 3 a of the member 3 is located in a substantially half range of the outer periphery of the rotating shaft 4 and is retracted so as not to enter the bill storage portion 11 and the conveyance path 18.

  As described above, in the present embodiment, the first impeller and the second blade are arranged on the left and right sides of the center in the longitudinal direction of the bills that are nipped by the feed roller and the reverse roller and fed into the storage unit when the bills are stacked. Because it is pressed alternately with the blades of the car, when you hit a bill with a habit that has a chevron in the center because it was in a folded wallet, only one side that was off the peak of the chevron of the bill was pressed with the blade Therefore, the banknotes are not misaligned and the banknotes can be reliably stacked in an aligned state.

  In addition, since the central part of the banknote is pressed by the first impeller and the second impeller, it is curled into a U-letter placed in a double-folded wallet, and the banknote whose central part is raised is accumulated, When stacking the banknotes, it is possible to prevent the banknote stacking from being obstructed by colliding with the raised central part of the banknotes previously stacked.

  The present invention is not limited to the above-described embodiments.

  For example, the impeller mechanism according to the above-described embodiment is applicable not only to a device for feeding and stacking banknotes but also to a device that handles media such as bonds and certificates, and to a device that only stacks these media. Is also applicable.
