Abstract

PROBLEM TO BE SOLVED: To surely deliver a paper sheet group one by one by moving a timing roller in the almost right-angled direction to a surface of the paper sheet group, and energizing the timing roller in the paper sheet group direction. SOLUTION: When sending out accumulated bills on a support plate 431, rotation of a driving motor is transmitted to a shaft 21 of a feed roller 13 via an output shaft, a pulley, a timing belt and a pulley to rotate the feed roller 13, and is transmitted to a shaft 18 via a gear 23 of the shaft 21, an intermediate gear 28 and a gear 20 to rotate a timing roller 12. At this time, a delivering swinging part 31 rotates with the shaft 21 of the feed roller 13 as the center by a tension coil spring 35 to impart downward energizing force to the timing roller 12 to position the timing roller 12 in the most sinking position. When an outer peripheral part 17 contacts with the uppermost bill by rotation of the timing roller 12, the delivering swinging part 31 moves so that the timing roller 12 rises by swelling of the outer peripheral part 17, and the timing roller 12 surely delivers the bill while directly pushing the bill.

Field of the Invention The present invention relates to a sheet processing apparatus for processing sheets, which is incorporated in a vending machine or the like, and a sheet sending mechanism used in the sheet processing apparatus. In particular, the present invention relates to a sheet sending mechanism characterized by a mechanism capable of reliably sending out sheets one by one, and a sheet processing apparatus using the sheet sending mechanism.

[0002]

2. Description of the Related Art FIG. 7A shows a conventional paper sheet sending mechanism.
This will be described with reference to FIG. Note that FIG.
It is EE cross section of (A).

The paper sheet sending mechanism 811 raises the paper sheets 951 stacked and placed on the support plate 931 of the safe section 920 for storing the paper sheets 951, with a part of the outer circumferential portion being raised. The raised outer peripheral portion 817 is the uppermost sheet 9
A timing roller 812 for feeding out the paper sheet 951 by contacting the sheet 51 is provided. The timing roller 812 is attached to the inner wall 921 of the safe 920. Since the timing roller 812 pays out the paper sheet 951 only while the raised portion per rotation, that is, the outer peripheral portion 817 is in contact, the paper sheet 951 is fed out intermittently. The support plate 931 is urged upward (toward the timing roller) by a spring (not shown). Therefore, this urging force is applied to the sheet 95 of the timing roller 812.
1 is generated.

[0004] The fed paper sheet 951 is further sandwiched between a feed roller 813 and a gap roller 814 and sent out, and exits outside the safe section 920. The feed roller 813 is attached to the inner wall 921, and further extends outward, and is also attached to the outer wall 922 of the safe 920. The timing roller 812 and the feed roller 813 are arranged above a bill dropper 933 having an opening 933A. The billboard 933 is connected to and attached to a lower portion of the inner wall 921. The outer wall 922 has a portion projecting further below the inner wall 921 (further below the billboard 933).

[0005] The gap roller 814 is attached to the outer wall 922. A gap is provided between the feed roller 813 and the gap roller 814 so that the sheets 951 are fed out one by one. The feed output for the paper sheet 951 is given by a feed roller 813,
The gap roller 814 rotates freely.

[0006]

According to the above-described conventional paper sheet feeding mechanism, the timing roller for feeding the paper sheet may not work well on the paper sheet and may cause a feeding error. The timing roller attempts a plurality of payouts. As a result, not only the sheets cannot be fed out, but also the orderly accumulation of the sheets may be broken.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sheet delivery mechanism capable of reliably feeding out a sheet, and a sheet processing apparatus provided with the sheet delivery mechanism.

[0008]

In order to achieve the above object, a paper sheet sending mechanism 11 according to the first aspect of the present invention comprises:
As shown in FIG. 1, a timing roller 12 configured to intermittently feed the uppermost sheet of the stacked sheet group; and a feed roller configured to feed the fed sheet. 13 and; feed roller 13
And a gap roller 14 having a predetermined gap and disposed opposite to each other; the timing roller 12 is movable in a direction substantially perpendicular to the surface of the paper sheet group and heads toward the paper sheet group. It is characterized in that it is biased in the direction.

With this configuration, the variation in the position at which the timing roller contacts the uppermost sheet is adjusted by the movement of the timing roller in a direction substantially perpendicular to the surface of the stacked sheet group, and is minimized. Can be kept to a minimum. Therefore, the uppermost sheet is reliably fed one by one by the timing roller, and the fed sheet is reliably sandwiched and sent out by the gap between the feed roller and the gap roller.

In addition, since the timing roller is urged in the direction toward the sheet group, the timing roller can directly apply an appropriate pressure to the uppermost sheet, and the uppermost sheet can be applied to the timing roller. Thus, a frictional force can be reliably applied to the sheet, and the paper sheet can be reliably fed.

Since the gap between the gap roller and the feed roller has a predetermined value, only the uppermost sheet is sent out by the feed roller. As described above, the gap roller forms a gap through which paper sheets pass between the gap roller and the feed roller.
The value of the gap is preferably larger than the thickness of one sheet and smaller than twice the thickness of the sheet. In addition,
The uppermost sheet refers to the sheet closest to the timing roller in the group of stacked sheets, and the sheet when the number of sheets is one.

According to a second aspect of the present invention, in the sheet delivery mechanism according to the first aspect, the movement of the timing roller is rotated about a rotation axis of the feed roller. It is characterized by movement.

Since the movement of the timing roller is a rotational movement about the rotation axis of the feed roller, the movement of the timing roller can be ensured with a simple structure.

According to a third aspect of the present invention, there is provided a paper sheet processing apparatus comprising: a transport mechanism for transporting circulated paper sheets; a storage mechanism for stacking and transporting the transported paper sheets; 3. The sheet sending mechanism according to claim 1 or 2, wherein the sheet sending mechanism sends out the sent sheets; and a return mechanism that returns the sent sheets outside.

Since the paper sheet processing apparatus according to the present invention includes the paper sheet sending mechanism according to the present invention, the paper sheets can be reliably sent out one by one, and the paper sheets can be reliably processed. .

Further, one end is connected to a fixed shaft 34 attached to the side wall 39, and the other end is connected to the rising portion 36A of the upper plate 36 of the feeding swinging portion 31, and the other end is connected to a pair of coil springs 35 (tensile springs). The swing unit 31 rotates counterclockwise in FIG. 1, that is, the timing roller 12 is on the lower side (in the direction of a thousand-yen bill).
It is urged toward.

Since the shaft 18 of the timing roller 12 and the shaft 21 of the feed roller 13 are disposed at substantially the same distance from the surface of the 1000-yen bill, the rotation about the shaft 21 of the feeding swinging portion The timing roller moves up and down in a direction substantially perpendicular to the surface of the 1,000-yen bill. The vertical movement direction may be substantially perpendicular to the surface of the 1,000-yen bill, and may be slightly inclined. For example, it may be about 75 degrees.

The amount of rotation of the feeding oscillating portion 31, that is, the amount of oscillating of the timing roller 12 in the vertical direction (in the direction approaching and moving away from the thousand-yen bill) is determined by the stopper pin 37 attached to the upper plate 36.
However, the swing amount in the downward direction is set to be a predetermined amount by contacting the regulating plate 38 attached to the inner wall 421. On the other hand, the upward swing amount is set to be a predetermined amount when the stepped portion 37A of the stopper pin 37 contacts the regulating plate 38. The swing amount may be adjustable.

Feed roller 13 and timing roller 1
Between the two large gears 28 coaxially arranged in parallel with each other
An intermediate gear 28 formed of an A and a small gear 28B is provided. The large gear 28A meshes with the gear 23, and the small gear 28B meshes with the gear 20. Therefore, the rotation of the drive motor 26 is transmitted to the feed roller 13 via the timing belt 25, and transmitted from the feed roller 13 to the timing roller 12 via the intermediate gear 28.

As shown in FIGS. 1 and 3, from a plane passing through the rotation center line of the feed roller 13 and perpendicular to the 1,000-yen bill,
A gap roller 14 is disposed at a position slightly deviated to the payout side, with its rotation center line positioned with a predetermined gap from the outer peripheral surface of the feed roller 13.
The gap roller 14 is configured to include two small rollers 14 </ b> A (see FIG. 5) arranged coaxially in parallel and in parallel.
It rotates clockwise CW3 in FIG. Gap roller 14
1 is mounted on the shaft 29 which is cantilevered from the outer wall 422 on the near side in FIG. One small roller 1
4A is located axially intermediate between the small roller 13A at one end and the intermediate small roller 13A. The other small roller 14A is located axially intermediate between the middle small roller 13A and the other small roller 13A (see FIG. 5). The shaft 29 is the shaft 21 and the shaft 1
8 are arranged in parallel with each other.

Further, a gap exists between the feed roller 13 and the gap roller 14, and the 1000-yen bill is sandwiched between the feed roller 13 and the gap roller 14 and passes through the gap. The gap is set to be larger than the thickness of the bill and smaller than twice the thickness of the bill.

In the vicinity of a plane passing through the rotation center line of the feed roller 13 and perpendicular to the 1,000-yen bill, the pay-out side end wall 30 of the safe section 420 of the 1,000-yen safe 400 is located. It regulates the movement of anything other than the upper layer in the payout direction. Two guides 33, 33 are provided on the upper side of the delivery side end wall 30.
Are spaced approximately equal to the width of the gap roller 14,
It is attached adjacent to the side surface of the gap roller 14 and guides a thousand-yen bill sent out by the feed roller 13.

The torque transmission between the timing roller and the feed roller is, for example, transmission by a belt, a frame in which the timing roller moves up and down is provided in the feeding swinging section, the timing roller can be moved up and down, and the timing roller is moved by a spring. May be biased from top to bottom.

Next, the operation of the bill sending mechanism 11 will be described with reference to FIG. Thousand-yen bills conveyed to the safe section 420 are sequentially accumulated on the support plate 431 in the safe section 420. When it is necessary to send out the 1000-yen bills accumulated on the support plate 431 in the safe section 420, power is supplied to the drive motor 26 (see FIG. 2) to be driven. The drive motor 26 rotates by supplying power, and the drive torque is controlled by the output shaft 26A and the pulley 2.
7, transmitted to the shaft 18 of the feed roller 13 via the timing belt 25 and the pulley 24 (see FIG. 2).
The feed roller 13 rotates. At this stage, since the 1000-yen bill is not applied to the feed roller 13, the 1000-yen bill is not sent out.

The rotation torque is controlled by the shaft 1 of the feed roller 13.
8 gear 23, to the large gear 28A of the intermediate gear 28, from the small gear 28B of the intermediate gear 28 to the gear 20, and further to the shaft 1
8 and the timing roller 12 rotates.

When the outer peripheral portion 17 is in contact with the uppermost 1000-yen bill by rotating the timing roller 12, the uppermost 1000-yen bill is placed between the outer peripheral portion 17 and the 1000-yen bill. It is paid out by the working frictional force in the feeding direction. The frictional force is such that the material of the outer peripheral portion 17 is a material having a high coefficient of friction with respect to the bill, the pressing force of the timing roller 12 against the 1,000-yen bill is sufficient, and the 1,000-yen bill is applied to the timing roller 12 side. And the timing roller 12 is biased toward the one-thousand-yen bill side, so that it can be reliably generated. When the outer peripheral portion 17 is not in contact with the uppermost 1000-yen bill, frictional force in the feeding direction does not work on this 1000-yen bill,
It is not delivered. Therefore, the 1,000 yen bill is intermittent (intermittent)
It is paid out.

At this time, the feed-out swinging portion 31 is rotated about the shaft 21 of the feed roller 13 by the tension coil spring 35, and the timing roller 12 is applied with a downward biasing force. 12 is in the lowest position. When the outer peripheral portion 17 comes into contact with the uppermost 1000-yen bill by the rotation of the timing roller 12,
The feeding swinging portion 31 moves so that the timing roller 12 rises in a direction away from the 1000-yen bill due to the bulging of the outer peripheral portion 17.

The outer peripheral portion 17 of the timing roller 12 directly presses the 1,000-yen bill with a predetermined pressing force by the tensile force of the coil spring 35, so that the frictional force acts more reliably than in the case where the tensile force by the coil spring 35 does not work. Is paid out surely.

The 1,000-yen bill fed by the timing roller 12 contacts the feed roller 13 and is further fed by the feed roller 13. A gap roller 14 is arranged substantially directly below the feed roller 13, and is set so that only one 1000-yen bill can pass through a gap between the feed roller 13 and the gap roller 14. When the uppermost 1000-yen bill is further fed by the feed roller 13 for a predetermined distance,
The 1000-yen bill is separated from the timing roller 12 and sent out only by the feed roller 13.

The 1000 yen bill on the top layer is the feed roller 1
3, the drive motor 26 rotates in the reverse direction, and only the feed roller 13 rotates in the reverse direction (CW2).
(The direction opposite to the above). Therefore, the 1000 yen bill is reliably sent out one by one.

Next, with reference to FIG. 6, a description will be given of a bill processing apparatus 1 as a paper sheet processing apparatus of the present invention, which is provided with a bill transmitting section 11 as a bill transmitting mechanism of the present invention. The banknote handling machine 1 includes a 1,000 yen safe 400, a 5,000 yen safe 500, and a 10,000 yen safe 600 as storage mechanisms, and circulates banknotes (1,000 yen bill, 5,000 yen bill, 10,000 yen) as paper sheets. Handle tags).

The bill inserted into the insertion slot 70 from outside is

1, 531, and 641, respectively, and are reserved.

If the return button (not shown) is pressed after the insertion of the bill, the bills sent out by the bill sending unit 11 are the 1,000-yen bill and the 5,000-yen bill held in the 1,000-yen safe 400 and the 5,000-yen safe 500. The sheets are reliably sent out one by one, transported by the transport units 701 and 702 as transport mechanisms, respectively, transported to the transport units 705 and 260 as transport mechanisms, and supported and held on the support plate 631 of the 10,000 yen safe. Then, all the banknotes are collectively returned to the return port 810 by the return unit 800 as a return mechanism.

After the insertion of the bills, when the purchase is made and the bills are paid out, all the reserved bills are once stored in the safes 400, 500, 600, respectively.
That is, in the 1,000 yen safe 400 and the 5,000 yen safe 500, the support plates 431 and 531 rise and the bill dropping plates 433 and
Thousand-yen bills and 5,000-yen bills abutting on the support plates 431 and 531 are dropped and stored on the mounting tables 432 and 532 in the safes 420 and 520, respectively. In the 10,000 yen safe 600, the bill dropping plate 641 is lowered and the 10,000 yen bills accumulated on the support plate 631 are transferred to the safe section 620.
And drop it on the mounting table 621 inside. Next, the number of bills to be refunded is sent out as a fishing bill, but a 10,000-yen bill is not usually paid out as a fishing bill.

When a fishing bill including a 5,000-yen bill is paid out, first, the 5,000-yen bill is surely sent out to the 10,000-yen safe 600 one by one by the bill sending section 11, and thereafter, the 1,000-yen bill is sent out. The bills are reliably sent out to the 10,000 yen safe 600 one by one by the bill sending unit 11. Therefore, the 5,000-yen bill and the 1,000-yen bill are stacked on the support plate 631 on the 10,000-yen safe 600 in order from the bottom. When all the bills to be paid out are accumulated, the bills are collectively paid out from the return port 810 by the return unit 800.
