However, the conventional medium feeding and accumulating apparatus described above has the following problems.
That is, the banknote (medium) 10 passes between the feed roller 102 and the gate roller 103 when the medium is accumulated. At that time, the banknote 10 has a brush roller 105 at both ends in the longitudinal direction as shown in FIG. In the state where 104 does not contact, it hangs down, and then, as shown in FIG. 11 (b), the bill 10 is pushed to move up and down like a flapping that both ends of the bill 10 are pushed up by the brush 104 of the brush roller 105. When discharging and stacking on the plate 106, the behavior of the bill 10 becomes unstable due to the operation like flapping, so that it is difficult to reliably scrape the rear end of the bill 10 with the brush 104 and stack. There is a problem that the state is disturbed.

  An object of the present invention is to solve such a problem.

  Therefore, the medium feeding and accumulating apparatus according to the present invention is fixed to a feed roller and a reverse roller that are installed facing the entrance / exit side of the medium storage unit, and a rotating shaft to which the reverse roller is attached so as to be positioned outside the reverse roller. A first impeller provided with blades at regular intervals over a range of about half of the outer periphery, and rotatably fitted to the rotary shaft so as to be positioned outside the reverse roller, and about half of the outer periphery A second impeller provided with blades at a constant interval over the range, a semicircular flange portion formed on the rotating shaft so as to be at the same position as the blades of the first impeller, Drive means for rotating the second impeller together with the rotating shaft when the first impeller rotates a certain amount together with the rotating shaft from a stopped state, and the medium fed through the transport path is the feed roller. River When the medium is discharged into the medium storage portion by the rotation of both rollers while being sandwiched between rollers, the flange portion located on the half circumference of the rotation shaft and the second circumference located on the half circumference opposite to the flange portion. The both ends in the longitudinal direction of the medium are pushed toward the feed roller by the blades of the impeller.

  In the present invention as described above, both ends in the longitudinal direction of the medium that is sandwiched between the feed roller and the reverse roller and fed into the storage unit when the medium is accumulated are provided on the pressing member that suppresses the axial movement of the second impeller. Since the flange portion and the blades of the second impeller are pushed toward the feed roller, when the medium is discharged onto the stage and accumulated, the both ends in the longitudinal direction of the medium can be operated like flapping. In addition, since the behavior of the medium is stable, the rear end of the medium can be reliably scraped off by the blades of the first and second impellers, and the effect that the medium can be collected in an aligned state is obtained. It is done.

The second impeller 2 is rotatably fitted on the outer periphery of the rotary shaft 4 so as to be separated from the first impeller 1 at a predetermined interval, and the pressing member 3 is opposite to the first impeller 1. 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.

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 4 between the first impeller 1 and the second impeller 2, and one end of the spring 26 is inserted and fixed in a horizontal 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.

When this rotation causes the blades 1a and 2a of the first impeller 1 and the second impeller 2 to move, and the first impeller 1 and the second impeller 2 rotate by a predetermined angle, 6 (c), the blades 1a and 2a come into contact with the bills 10 stacked in the middle of the rotation path, whereby the blades 1a and 2a receive a contact load from the bills 10.
Here, as described with reference to FIG. 4, 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 the rotating shaft 4 adds a rotational force to the second impeller 2 by the pin 25 and the protrusion 2b. The impeller 2 rotates in the clockwise direction together with the rotating shaft 4 and the first impeller 1.

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 is 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, when the banknote 10 is lowered so as not to contact the blades 2a of the second impeller 2 as shown in FIG. 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.

By disposing within the range of the length of the bill 10 in the longitudinal direction, the blades of the first impeller 1 and the second impeller 2 even for such a bill 10 having the shortest length in the longitudinal direction. It can be drawn by hitting with 1a and 2a.

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 first embodiment having the above-described 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 a position where the detected portion 7a of the positioning member 7 fixed to the rotating shaft 4 shown in FIG. 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 in a range approximately half of the outer periphery of the rotating shaft 4 as shown in FIG. It is retracted so as not to enter the banknote storage unit 11 and the conveyance path 18.

  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 reverse roller 17 is rotated into the bill storage unit 11. At this time, both end portions in the longitudinal direction of the bill 10 are the flanges 2 a of the second impeller 2 and the pressing member 3 as shown in FIG. 7. By 3a, it hold | maintains so that operation | movement like flapping may not be carried out.

  That is, as shown in FIG. 7A, when the blade 2a of the second impeller 2 is downward, the blade 1a of the first impeller 1 and the flange portion 3a of the pressing member 3 are directed upward to assist. The roller 27 overlaps. Since the flange portion 3a is outside the auxiliary roller 27, for example, when the bill portion 10 is sandwiched between the feed roller 13 and the reverse roller 17 when the flange portion 3a of the pressing member 3 is upward, both longitudinal end portions of the bill 10 are provided. 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 are directed downward. At this time, the blade 2a of the second impeller 2 is directed upward. Go. Since the second impeller 2 is also outside the auxiliary roller 27, when both longitudinal end portions of the banknote 10 are separated from the flange portion 3a of the pressing member 3, the blade 2a of the second impeller 2 is suspended before it hangs downward. And is pushed up by the elasticity of the blade 2a.

As described above, the both ends in the longitudinal direction of the banknote 10 are the flanges 2 a of the second impeller 2 and the flange of the pressing member 3 while the banknote 10 is fed into the banknote storage 11 by the rotation of the feed roller 13 and the reverse roller 17. It is always pushed up by the part 3a and discharged into the banknote storage part 11 without flapping.
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.

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.

  According to the first embodiment described above, the movement of the second impeller in the axial direction is regulated at both ends in the longitudinal direction of the bill that is sandwiched between the feed roller and the reverse roller and fed into the storage portion when the bills are stacked. Since the flange portion provided on the pressing member and the blades of the second impeller are pushed toward the feed roller, when the bills are discharged and accumulated on the stage, the both ends in the longitudinal direction of the bills are flapping. Since the behavior of the banknote is stable without any action, the trailing edge of the banknote can be reliably scraped off by the blades of the first and second impellers, and the banknotes are stacked in an aligned state. The effect that it can be obtained.

FIG. 8 is a front view of the second embodiment, and FIG. 9 is a second impeller 2 in the second embodiment.

Since other configurations are the same as those of the first embodiment, the same portions are denoted by the same reference numerals and the description thereof is omitted.

In the second embodiment having such a configuration, the operation at the time of bill feeding is performed in the same manner as in the first embodiment.
In this case, the flange portion 2d of the second impeller 2 is formed so as to be adjacent to the blade 2a as described above, so that the blade 2a does not enter the bill storage portion 11 and the conveyance path 18. When retracting, the flange portion 2d can be retracted in the same manner.

  Although the operation at the time of banknote accumulation is performed in the same manner as in the first embodiment, the blades 1a and 2a of the first impeller 1 and the second impeller 2 are radially spread over the entire circumference of the rotating shaft 4. At this time, the flange portion 3 a of the pressing member 3 located at the same position as the blade 1 a of the first impeller 1 and the flange portion 2 d located at the same position as the blade 2 a of the second impeller 2 extend over the entire circumference of the rotating shaft 4. In order to unfold so as to form one disc, the paper 10 is sandwiched between the feed roller 13 and the reverse roller 17, and while the bills are fed into the bill storage unit 11 by the rotation of both rollers 13, 17, the longitudinal direction of the bill 10. Both end portions are pushed up by the flange portion 3a of the pressing member 3 as shown in FIG. 8A, or by the blade 2a and the flange portion 2d of the second impeller 2 as shown in FIG. 8B. Pushed up.

As described above, the both ends in the longitudinal direction of the bill 10 are pressed against the blade 2a and the flange portion 2d of the second impeller 2 while the bill 10 is fed into the bill storage portion 11 by the rotation of the feed roller 13 and the reverse roller 17. It is always pushed up by the flange part 3a of the member 3, and is discharged into the banknote storage part 11 without performing an operation like flapping.
Thereafter, the blades 1a, 2a, the flange portion 2b, and the flange portion 3a of the pressing member 3 of the first impeller 1 and the second impeller 2 are positioned in a substantially half range of the outer periphery of the rotary shaft 4, and the bill storage portion 11 and the first embodiment until it is retracted so as not to enter the transport path 18.

In the second embodiment described above, the same effect as that of the first embodiment can be obtained. In addition, in the second embodiment, the second impeller 2 is provided with a flange portion so that both end portions in the longitudinal direction of the banknote are provided. Since the push-up is performed, a more stable integration operation is possible.
