Description of the Related Art In recent years, a mail classification is provided which has a recognition function of reading a bar code attached to a mail or a character recognition function of reading address information such as a zip code, and automatically sorts and processes the mail from the address information. The device has been put to practical use. In such a paper sheet sorting apparatus for postal items (hereinafter referred to as "paper sheet"), space saving, small number of people work,
Low cost and high speed are required. Among them, in order to realize high speed, as one of them, it is required to eliminate troubles such as double feeding during transportation and to perform transportation and sorting processing operation quickly and accurately.

By the way, generally, in this kind of paper sheet sorting apparatus, a plurality of paper sheets to be sorted are put into a bundle in a state of being put up in a bundle, and the sheets are separated one by one in a separating and supplying section, A structure is adopted in which the separated paper sheets are sandwiched between a pair of rotating conveyor belts and sent in sequence to the paper sheet sorting section, and the separation and feeding of the paper sheets in the separation and supply section is appropriate and quick. In addition to the above, it is necessary to send the paper sheets to the paper sheet sorting section at intervals that can be sorted in the transport section. Therefore, the paper sheets fed out in the separation and supply unit are also
It is required to be fully prepared before it is placed in the separation supply section. Therefore, there is also known a structure in which the sheets fed in a bundle at the preceding stage of the separating / supplying unit are vibrated to be aligned (aligned), and at the same time, conveyed to the separating / supplying unit by another transfer means. ing.

Corresponding to the above, the paper sheet relay path 5a is provided by being divided into upper and lower three stages.

Corresponding to the sorting and accumulating section 3a of the paper sheet sorting section 3, the storage rack 6 has 11 sheets of paper sheet storage paths 6a arranged side by side in a row, and three rows are vertically formed. ing.

(Schematic Structure of Paper Sheet Supply Unit 1) FIG. 4 is a perspective view schematically showing the structure of the main part of the paper sheet supply unit 1, and FIG. It is a perspective view which partially expands and shows the peripheral structure of the leaf feeding position 8.
In FIGS. 4 and 5, the paper sheet feeding unit 1 includes a paper sheet 1
A plurality of 0s are bundled into a bundle, and the charging unit 11 is charged in a standing posture.

(Structure of Inserting Section) As shown in FIGS. 6 and 7, the inserting section 11 has a bottom wall 11a for receiving a bottom portion of the inserted sheet 10 and a back surface of the sheet 10. And a back wall 11b for receiving the above-mentioned part. The bottom wall 11a and the back wall 11b are formed in a substantially L-shaped cross-section so as to intersect each other at about 90 degrees, and the back wall 11b and the bottom wall 11a as a whole have a rearward θ degree (about 15 degrees). It is in a tumbled state (see FIGS. 3 and 7). 6 is a perspective view schematically showing the structure of the main part of the charging unit 11, and FIG. 7 is a schematic sectional view taken along the line AA of FIG.

The peripheral structure of the input section 11 will be further described. On the back wall 11b side, the paper sheets 10 on the input section 11 are fed horizontally toward the paper sheet feeding position 8 while standing. A paper sheet transfer means 12 capable of performing the above is provided. The back wall 11b includes an upper back plate 13a and an intermediate back plate 13a.
The three plates b and the lower back plate 13c are provided with slits 14a and 14b between the upper back plate 13a and the intermediate back plate 13b and between the intermediate back plate 13b and the lower back plate 13c, respectively. Combined to form one back wall. The widths of the back plates 13a to 13c here are not the same, and the upper back plate 13a, the intermediate back plate 13b, and the lower back plate 13c become smaller in this order. Further, the back plates 13a to 13c are not arranged on the same plane, and as shown in FIG. 7, the intermediate back plate 13b is slightly retracted to the rear side by the dimension t rather than the upper back plate 13a. , Lower back plate 1 than intermediate back plate 13b
3c is slightly retracted to the rear side by the dimension t, and is arranged in a stepwise manner such that it is sequentially retracted as it approaches the bottom wall 11a. As described above, the three back plates 13a having different widths forming the back wall 11b
By sequentially shifting the position of 13c to the rear side, the paper sheet 10 being aligned due to vibration is flipped up, and when the paper sheet 10 is next dropped, the lower back angle of the paper sheet 10 (bottom surface and back surface) Back plate 1 in which slits 14a and 14b are formed at the intersection of
The upper surface of 3b and the upper surface of the back plate 13c are not caught. In the conventional arrangement, the back plates 13a to 13c provided with the slits 14a and 14b are arranged in the same plane, and this forms a step between the back plates 13a to 13c with respect to the vertical direction in the insertion portion. When the paper sheet 10 is dropped along the back wall 11b in that state, the lower corner of the paper sheet 10 is caught in the step, and the upper side of the paper sheet approaches the front. A rotational force is applied in the coming direction, and the paper sheet 10 has a bad posture. Therefore, as in the present embodiment, the back plate 13a ...
If 13c is arranged so as to retract, a step in the vertical direction does not occur, so a protruding step is not created. Therefore, the paper sheets 10 falling along the back plate 13a are not caught on the upper surfaces of the back plates 13b and 13c, and the paper sheets 10 can be smoothly aligned to the bottom wall 11a without squeezing forward. A reliable alignment can be performed without disturbing the posture of the paper sheets on the way. Further, even if the paper sheet 10 is aligned and falls while rotating in the clockwise direction in FIG. 7, the upper surfaces of the back plates 13b and 13c retreat more than the back plates 13a and 13b immediately above, respectively. Since the paper sheet 10 is in the closed position, the lower back corner of the paper sheet 10 is not caught, and similarly, the posture of the paper sheet in the middle of alignment is not disturbed again, and reliable alignment can be performed.

On the other hand, on the side of the bottom wall 11a, the paper sheet 10 placed on the feeding section 11 is vibrated, and the two sides (the lower side and the back side) of the paper sheet 10 are respectively attached to the bottom wall. Paper sheet vibrating means 15 (see FIG. 4, FIG. 5, FIG. 19) for bringing the paper sheets 10 into contact with 11a and the back wall 11b and aligning them.

It is made so that the amount of protrusion is the maximum when finished. On the other hand, the first cam 23A is
It is formed as one pillar-shaped rail material, and the second
It is arranged so as to be continuously connected to the end portion of the cam 23B (the maximum protruding portion of the inclined surface 23b), and the maximum protruding amount is maintained so that the sheet feeding position 8
It extends straight toward the (end 12A) and toward the paper sheet feeding position 8. The position of the first cam 23A on the sheet feeding position 8 side is the arm 18 of the partition arm portion 19 that has been moved to the sheet feeding position 8 most.
a and 18b are disposed to a position just before the sheets 10 are arranged between them and are brought into contact with the belt contact surface 67a of the separation / supply belt 67 in the paper separation / supply device 9.
The rollers 40 of the partition arm portion 19 are arranged so as to be in contact with each other. A pair of front and rear guide bars 24a and 24b are arranged along the first cam portion 23A near the first cam portion 23A (see FIGS. 10 and 11). A pair of front and rear guide bars 24a, 24
b are held parallel to each other via a spacer 25 fixed to the apparatus main body side, and head toward the paper-sheet feeding position 8 in a state of being folded back from the lower side and being in contact with the first cam 23A. The upper half of the endless chain 21 is supported from below.

(Structure of Partition Arm Unit) Partition Arm Unit 1
As shown in detail in FIGS. 12 to 17, reference numeral 9 designates a mounting plate 26 fixedly mounted on the pair of front and rear chains 20 and fixed to front and rear ends of the mounting plate 26, respectively. Brackets 27a, 27
a pair of guide bars 28a, 28b and a center bar 29 whose front and rear ends are fixed to the guide bar 2
8a, 28b and a slider 30 attached to the center bar 29 so as to be slidable in the front-rear direction, an arm holder 31 fixedly attached to the slider 30, and an arm holder 31 fixedly attached to the arm holder 31. It is composed of the pair of arms 18a and 18b. Further, as shown in the exploded perspective view of FIG. 15, the slider 30 has through holes 30a and 30b penetrating forward and backward at left and right positions and also penetrating forward and backward at a central position. It has a through hole 30c. A cylindrical slide bush 32 is inserted into the through holes 30a and 30b.
2 is fixed to the slider 30 by a snap ring 33 attached to a slide bush 32 before and after the slider 30. The guide bars 28a and 28b pass through the slide bush 32 and penetrate the slider 30, and both ends are fixedly attached to the brackets 27a and 27b with screws 34, and hold the slider 30 slidably in the front-rear direction. When the slider 30 is mounted on the guide bars 28a and 28b, a ring-shaped spacer 35 for restricting the sliding amount of the slider 30 is mounted between the slider 30 and the bracket 27b. The center bar 29 has the through hole 3 of the slider 30.
It is arranged in parallel with the guide bars 28a and 28b penetrating 0c, and both ends penetrate the brackets 27a and 27b, and are positioned and fixed by the E ring 36 outside the brackets 27a and 27b. Further, between the bracket 27a and the slider 30, a coil spring 37 is mounted on the center bar 29 in a compressed state, and the slider 30 is always mounted on the bracket 27b.
It is in a state of being pressed to the side (see FIGS. 12 and 13). The arm holder 31 is formed in a substantially L shape, and with the standing piece 31a facing the front, a horizontal piece 31b bent from the lower end side of the standing piece 31a toward the rear at a substantially right angle is formed. It is attached by fixing it to the upper surface of the slider 30 with a screw 38. The upright piece 31a includes a pair of arms 1 separated from each other vertically.
8a and 18b are attached in a state in which they project toward the front at a substantially right angle. On the other hand, on the rear end side of the horizontal piece 31b, a roller 40 is attached which is horizontally rotatable about a pivot 39 extending upward from the horizontal piece 31b at a right angle. The roller 40 corresponds to the first cam 23A and the second cam 23B and can come into contact with the first cam 23A and the second cam 23B.

The driving means 22 is divided into the left and right ends of the charging section 11 and is rotatably arranged on the rotary drums 41A, 4A.
1B, and gears (not shown) to be engaged with the chain 20 are integrally formed on the outer circumferences of the respective rotary drums 41A and 41B. When the rotary drums 41A and 41B rotate, the gears and the chain 20 are sequentially meshed with each other, and the endless chain 21 travels endlessly integrally with the partition arm portion 19 in the rotation direction of the rotary drums 41A and 41B. Of the rotary drums 41A and 41B, the rotary drum 41A is a drive drum, and the rotary drum 41A
B is a driven drum, and the rotary drum 41A is rotated by receiving the rotational driving force from the motor 42. That is,
When the motor 42 is rotated, the rotary drum 41A is rotated, and the rotation of the rotary drum 41A is changed by the chain 20.
In this structure, the rotary drum 41B is driven to rotate, and thereby the endless chain 21 is rotated endlessly.

In the construction of the above-mentioned paper sheet transfer means 12,
The operation of the partition arm portion 19 will be described next. When the partition arm portion 19 corresponds to the first cam 23A,
0 is in contact with the first cam 23A and resists the repulsive force of the coil spring 37.
As shown in a part of 6, the arms 18a and 18b are pushed toward the bracket 27a side and largely protrude forward from the back wall 11B. And this arm 18
Slit 1 with a and 18b still protruding greatly
The inside of 4a, 14b is moved from the end 12B side toward the end 12A (paper sheet feeding position 8) with the rotation of the endless chain 21. At this time, a plurality of parts are provided on the insertion part 11 in a state of being subdivided between the partition arm part 19 and the partition arm part 19 and supported by the arms 18a, 18b and the arms 18a, 18b from both sides and standing in a bundle. The paper sheets 10 that have been put in collectively are pushed by the arms 18a and 18b, accompanied by the transfer by the second paper sheet transfer means 16 described later and the vibration of the paper sheet vibrating means 15, and the paper sheet feeding position. Moved to 8. Also, the partition arm portion 19
When the roller 40 is moved to the paper sheet feeding position 8 and the roller 40 is disengaged from the first cam 23A, the slider 30 is guided by the guide bars 28a, 28b by the repulsive force of the coil spring 37, and the sliders 30a, 30b, 30a, and 30b in FIG. As shown in a part of FIG. 16, it instantaneously moves to the bracket 27b side. That is, by this movement, the arms 18a and 18b are retracted to the position where the tip ends are on the rear side of the back wall 11b. 16
The peripheral structure of this paper sheet feeding position 8 is shown, and the arms 18a and 18b of the partition arm portion 19 which is not disengaged from the first cam 23A project forward and the arm of the partition arm portion 19 which is disengaged from the first cam 23A. 18a, 18b is the back wall 1
1B shows a state in which the position is retracted to the rear side.

Then, at the paper feeding position 8, the arm 1
The partition arm portion 19 that has been retracted to a position where the back walls 11b are located at 8a and 18b is moved to the other end 12B by the endless chain 21 while the arms 18a and 18b remain retracted, and the other end Immediately before 12B, the roller 40 is brought into contact with the minimum height position of the inclined surface 23b of the second cam 23B. Further, when the roller 40 is moved together with the endless chain 21 while being in contact with the inclined surface 23b, the height of the contacted inclined surface 23b gradually increases, and due to the cam action of the inclined surface 23b. The slider 30 is gradually moved toward the bracket 27a side while compressing the coil spring 37, whereby the arm 18
The a and 18b again largely project to the front side of the back wall 11b. FIG. 17 shows the roller 4 at the other end 12B in this way.
0 is in contact with the inclined surface 23b of the second cam 23B, and the arms 18a and 18b are projected.
This protrusion is maximized at a position adjacent to the first cam 23A, and when reaching the end of the second cam 23B, the first cam 2
3A, the sheet is fed toward the sheet feeding position 8 while being again in contact with the first cam 23A. In addition,
Immediately before moving from the second cam 23B to the first cam 23A, the arms 18a and 18b again correspond to the slits 14a and 14b, and are moved to the sheet feeding position 8 through the slits 14a and 14b.

Therefore, in the structure of the present embodiment, when the roller 40 moves while being in contact with the first cam 23A, the arms 18a and 18b project toward the paper sheet feeding position 8 with the arms 18a and 18b protruding from the back wall 11b. And the partition arm portion 19 approaches the sheet feeding position 8 and the roller 4 moves.
When 0 is disengaged from the first cam 23a, the arms 18a, 18
It is retracted together with the slider 30 to a position where b is the rear side of the back wall 11b. Further, the arms 18a and 18b are moved toward the other end 12B in the retracted state, and the other end 1
When approaching 2B, the roller 40 comes into contact with the second cam 23b. If it is moved as it is, the slider 30 will move to the arm 1.
The cycle of being carried to the first cam 23 again while being projected forward together with 8a and 18b is repeated. Then, by this operation, the paper sheets 10 placed on the input unit 11 can be sequentially moved toward the paper sheet feeding position 8.

In the structure of the present embodiment, the position of the end of the first cam 23A on the sheet feeding position 8 side is the last position where the arms 18a and 18b carry toward the sheet feeding position 8. The paper sheet 10 is set so that it can support the paper sheet feeding position 8 until just before it can lightly touch the separating and feeding belt 67 of the paper sheet separating and feeding device 9, which will be described later. It has been described above that the arms 18a and 18b are instantaneously retracted when the paper sheet 10 is lightly touched by the paper sheet separating / supplying device 9.
With such a structure, the last sheet is transferred at the sheet feeding position 8 until the belt contact surface 67a of the separating and feeding belt 67 of the sheet separating and feeding device 9 is lightly touched. It will be possible to deliver it without fail. By the way, in the paper sheet transfer means in the conventional device,
When the arm retracted, it was impossible to retract immediately before the sheet feeding position. In addition, the mechanism for selecting the retreat operation causes the retreating arm to accelerate or decelerate the advancing speed to the paper sheet delivery position with respect to the arm that is being transferred later, and the arm interval is also narrowed or narrowed. It was a cause of double feed. Also, the arm itself cannot momentarily retract, and the arm gradually and slowly retracts before the arm reaches the sheet feeding position. In other words, since the arm of the paper sheet transfer means of the conventional device cannot reach the position immediately before the paper sheet feeding position in a protruding form, the paper sheet that falls backward and falls down to the separating and feeding surface (belt contact surface). In order to bring them into contact with each other, it is necessary for the worker to directly support the paper sheets, which poses a problem in safety and realization of one-person work. On the other hand, in the structure of the present embodiment, the belt contact surface 67a of the paper sheet separating / feeding device 9 is
Since the arms 18a and 18b project until just before the last sheet of paper 10 comes into contact with the sheet of paper 10, the sheet of paper 10 is contacted before the sheet of paper 10 comes into contact with the belt contact surface 67a. It is possible to eliminate a situation in which 10 is tilted backward to cause poor transfer. As a result, it is possible to eliminate the arrangement of a dedicated worker or the like, which is required in the conventional apparatus, for handling the problem caused by the subsequent fall, and it is possible to reduce the number of personnel and the cost. Further, in the structure of the present embodiment, the position of the first cam 23A on the sheet feeding position 8 side,
That is, the roller 40 of the partition arm portion 19 is connected to the first cam 2
The position at which the arms 18a and 18b can be retracted from the contact of 3A has a structure that can be arbitrarily adjusted.

Next, the construction of the paper sheet vibrating means 15 on the side of the bottom wall 11a on the side of the feeding section 11 and the second paper sheet conveying means 1
The configuration of No. 6 will be described. (Configuration of Second Paper Sheet Transfer Means) First, the configuration of the second paper sheet transfer means 16 will be described. The second paper sheet transfer means 16 is shown in detail in FIG. The second paper sheet transfer means 16 includes a pair of front and rear transfer belt means 43A and 43B extending in the left-right direction in parallel with the endless chain 21 on the back wall 11b side, and a pair of front and rear transfer belt means 43A and 43B and the paper. Between the leaf feeding position 8, a pair of front and rear auxiliary transfer belt means 44A, 44B partially overlaps the transfer belt means 43A, 43B and extends in the left-right direction. The pair of front and rear auxiliary transfer belt means 44A, 44B are disposed so as to be located between the transfer belt means 43A, 43B.

The transfer belt means 43A and 43B include a drive pulley 46a, a driven pulley 46b, and the drive pulley 4a.
6 a and the driven pulley 46 b, and an endless belt 47 that is stretched around the driven pulley 46 b. The upper surface of the endless belt 47 is the opening 1 of the bottom wall 11 a of the feeding section 11.
It is provided so as to project upward from 1c (see FIG. 6),
The endless belt 47 directly receives the paper sheet 10 placed on the input section 11, and when the endless belt 47 rotates, the paper sheet 10 is fed by the paper sheet transfer means 12 and fed out. It can be sent to position 8. Further, the drive pulley 46a is the paper sheet transporting means 1
2 receives the driving force of the motor 42 driving the motor 2 via a power transmission belt (not shown) to rotate the driving pulley 46a.
The endless belt 47 and the driven pulley 46b also rotate following the rotation.

The auxiliary transfer belt means 44A and 44B are composed of a drive pulley 49a and a driven pulley 49b, and an endless belt 50 which is stretched between the drive pulley 49a and the driven pulley 49b. The surface of the endless belt 50 is formed so as to be smoother than the surface of the endless belt 47 used in the transfer belt means 43A and 43B so that the frictional force between the endless belt 50 and the paper sheet 10 can be reduced. The upper surface of the endless belt 50 is provided so as to project upward from the opening 11d (see FIG. 6) of the bottom wall 11a of the input unit 11, and the paper sheet 10 placed on the input unit 11 is attached to the endless belt 50. Directly on the 50,
When the endless belt 50 rotates, the paper sheet 1
It is structured such that 0 can be sent to the paper sheet feeding position 8 together with the paper sheet feeding means 12 or, in the opposite direction, away from the paper sheet feeding position 8. The rotation of the endless belt 50 is such that when the drive pulley 49a receives the driving force of the motor 51 capable of rotating in the forward and reverse directions and rotates in the positive or negative direction, the drive pulley 4a.
This is because the endless belt 50 and the driven pulley 49b rotate in the positive or negative direction following the rotation of 9a.

Auxiliary transfer belt means 44A, 44B
Is capable of rotating in both forward and reverse directions, when the paper sheets 10 are fed one after another in the area of the paper sheet feeding position 8 and are pushed too much, the paper sheet transfer means 12 and This is for stopping the conveyance by the transfer belt means 43A, 43B and reversing the endless belt 50 immediately before separation so that the paper sheet 10 is returned once and the excessive pushing is alleviated. That is, normally, in the same direction (counterclockwise direction in FIG. 20A) as the direction in which the paper sheet transfer means 12 and the second paper sheet transfer means 16 are transferring the paper sheet 10. , While rotating with the paper sheet 10 at a high speed (rotational speed faster than the rotational speed at which the paper sheet transfer means 12 and the transfer belt means 43A, 43B are conveying the paper sheet 10). Immediately before the paper sheet feeding position 8, a counterclockwise force is also applied to the paper sheet 10, and the upper end side immediately before the paper sheet feeding position 8 is the belt surface 6 of the separation supply belt 67.
The paper sheet 10 is provided with an action of falling toward 7a. As a result, the paper sheet 10 can be easily brought into contact with the separation / supply belt 67. Further, for some reason, when the first sheet 10 is pressed too strongly against the separation / supply belt 67, it is detected by the over-pressing detection sensor 94 described later. When over-pressing is detected, the motor 51 is rotated in the opposite direction and the endless belt 50 rotates in the opposite direction (clockwise direction in FIG. 20B), but the endless belt 50 rotates counterclockwise. When the endless belt 50 is rotated at a high speed, the endless belt 50 rotates at high speed while causing a slippage between the endless belt 50 and the paper sheet 10 and also applies a counterclockwise force to the paper sheet 10 pressed against the separation supply belt 67. The sheet 10 is provided with an action of rotating the upper end side in a direction away from the belt surface 67a of the separation supply belt 67 and inclining. As a result, the space between the paper sheets 10 that have been transported to immediately before the separation / supply belt 67 is separated, and only one paper sheet 10 is adsorbed by the separation / supply belt 67 as described below, Make it easy to extend to the side. Here, the surface of the endless belt 50 is
As described above, the reason why the endless belt 50 is made smooth so that the frictional force with the paper sheet 10 can be reduced is as follows.
The paper sheet transfer means 12 and the transfer belt means 43 at all times.
Since A and 43B rotate the paper sheet 10 at a speed higher than the speed at which the paper sheet 10 is conveyed, when the frictional force is large, the paper sheet 10
There is a risk of peeling scratches on the lower surface of the, but if the surface is made smooth to reduce friction, that concern will disappear.
Further, the frictional force between the paper sheet 10 is large, and the paper sheet 10
If the endless belt 50 rotates in the same forward direction as the direction in which the paper sheet transporting means 12 and the transport belt means 43A, 43B are transporting the paper sheet 10, the paper sheet is not slipped. When the lower end of 10 is kicked and the paper sheet 10 is rotated immediately in front of the separation / supply belt 67, the upper end of the paper sheet 10 is rotated in a direction away from the separation / supply belt 67 side. , The lower end of the paper sheet 10 is kicked and moved while scooping, and the upper end side is separated and fed by the separation belt 67.
Can't be far apart.

(Structure of Paper Sheet Vibrating Means) The paper sheet vibrating means 15 has an endless belt 47 between the transfer belt means 43A and 43B as shown in the detailed structure of FIG.
Slender up-and-down movable member 52 extending in the left-right direction in parallel with
a and 52b, and a vibration generating means 53 for alternately moving the vertically movable members 52a and 52b up and down.
The vertically movable members 52a and 52b can be projected or retracted on the bottom wall 11a through an opening 11e (see FIG. 6) provided in the bottom wall 11a.

The vibration generating means 53 has an eccentric cam 54 on its peripheral surface.
A rotary shaft 54 integrally provided with a and 54b, a drive means 55 for rotating the rotary shaft 54, and an eccentric cam 54a,
Cam rings 56a, 56b as link pieces for transmitting the cam action of 54b to the vertically movable members 52a, 52b.
And the eccentric cam 54a.
The cam ring 56b is rotatably attached to the eccentric cam 54b. In the present embodiment, the eccentric cam 54a and the eccentric cam 54b are arranged so as to be offset from each other by 180 degrees in the rotational direction. In addition, the cam rings 56a and 56b are provided on the upper and lower movable members 52.
When the cam rings 56a and 56b move up and down by the eccentric cams 54a and 54b by being connected to the centers of the a and 52b via the bracket 56c and the pivot 56d, the eccentric cams 54a and 54b move up and down to interlock with the cam rings 56a and 56b. The vertically movable members 52a and 52b are also vertically movable. Further, pulling means 58 having a coil spring 57 that keeps the vertically movable members 52a and 52b constantly pulled downward is provided on both left and right sides of the vertically movable members 52a and 52b.

The driving means 55 includes a motor 59, a pulley 60 that is integrally rotatable with an output shaft 59a of the motor 59, a pulley 61 that is integrally rotatable with the rotating shaft 54, and a pulley 60. And a power transmission belt 62 stretched over the pulley 61. The rotation of the motor 59 is transmitted to the output shaft 59a, the pulley 60, the power transmission belt 62, and the pulley 61, and the pulley 6
The structure is such that the rotary shaft 54 can be rotated integrally with 1.

The paper sheet vibrating means 15 configured as described above
Then, when the rotating shaft 54 is rotated by the motor 59, the eccentric cams 54a and 54b push up one of the up and down movable members 52a and 52b via the cam rings 56a and 56b and pull down the other, such that the up and down movable members 52a and 52b are pulled down.
Alternately move b up and down. That is, one vertically movable member 52a (or 52b) passes through the opening 11e and the bottom wall 1
If it projects from 1a, the other vertically movable member 52b (or 52a) moves so as to retract from the bottom wall 11a. In addition, the entire input unit 11 is in a state of being inverted to the rear side by about 15 degrees, and the weight of the paper sheet 10 is divided into a rear direction and a bottom direction, and the vertically movable member 52.
Since both a and 52b push up the position deviated from the center of the bottom side of the paper sheet 10 from the lower side, vibration is applied by rotating the paper sheet 10 with the corner portion where the bottom surface and the back surface of the paper sheet 10 intersect as a fulcrum. In addition, the two vertically movable members 52a and 52b
Are provided apart from each other in the front and rear, the position where the bottom surface of the paper sheet 10 is pushed is different, and the vertical movable member 52b on the front side is projected to vibrate the paper sheet 10 and the vertical movable member on the rear side. It is possible to give different amplitudes when the sheet 52 is vibrated and the paper sheet 10 is vibrated, and at the same time, it is possible to give different magnitudes of rotational force, resulting in efficient and proper alignment (alignment) in a short time. Can be performed.

(Structure of Paper Sheet Separation / Supply Device) Next, the paper sheets 10 sent to the paper sheet feeding position 8 are separated one by one and fed toward the paper sheet conveying means 4. The structure of the paper sheet separating / supplying device 9 will be described. The detailed structure of the paper sheet separating and supplying apparatus 9 is shown in FIGS. 5 and 20 to 23. 5A and 5B are perspective views showing the peripheral structure of the paper sheet separating / supplying device 9 at the paper sheet feeding position 8 of the paper sheet supplying unit 1, and FIGS. 20A and 20B show the paper sheet separating operation. FIG. 21 is a diagram schematically showing the peripheral structure and operation of the feeding device 9, FIG. 21 is an overall perspective view of the paper sheet separating and feeding device 9, FIG. 22 is a front view of the paper sheet separating and feeding device 9, and FIG. It is a top view of the class separation supply apparatus 9. In FIGS. 5 and 20 to 23, the paper sheet separating and supplying device 9 is moved to the paper sheet feeding position 8 in an upright position by the paper sheet transfer means 12 and the second paper sheet transfer means 16. A separation supply unit 63 capable of vacuum-sucking the received paper sheet 10 and adsorbing only one sheet, and transporting this substantially vertically toward the paper sheet conveying unit 4 on the downstream side, and the separation thereof. A separation assisting unit 64 for facilitating the separation of the paper sheets 10 one by one in the supply unit 63, and a paper sheet for detecting the presence or absence of the paper sheet 10 sent to the paper sheet feeding position 8. It is composed of a class detecting means 106 (see FIG. 28), a paper sheet excessive pressing detecting means 105 (see FIG. 28), and the like.

(Structure of Separation and Supply Section) The separation and supply section 63 is
An endless separation / supply belt 67 stretched around the outsides of the three guide rollers 66a, 66b, 66c.
A vacuum suction means 68 for vacuuming and holding the paper sheet 10 conveyed to the separation supply belt 67 by the separation supply belt 67, and the paper sheet 10 sent to the separation supply section 63. Paper sheets that were supplied with the size and posture of the
It is composed of three sensors 69a, 69b, 69c and the like for detecting the existence of 0 or a paper sheet having a posture defect due to alignment and sending output information to the posture defect detection means 115 (see FIG. 28). .

Three guide rollers 66a, 66b, 66
Among c, the two guide rollers 66a and 66b are vertically arranged along the direction in which the paper sheet 10 is fed, and the remaining one guide roller 66c is arranged on the rear side. . Therefore, a portion 67a of the separation / supply belt 67 stretched by these three guide rollers 66a, 66b, 66c, facing the sheet feeding position 8 (hereinafter, this portion will be referred to as "belt contact surface 67a").
Is a plane (vertical surface) so that it runs straight up and down. The guide rollers 66a and 66b are driven rollers rotatably attached to the pivots 70a and 70b, and the guide roller 66c is a drive roller integrally rotatably attached to a drive shaft 70c rotated by a motor 71. When the drive shaft 70c is rotated together with the guide roller 66c by the motor 71, the separation supply belt 67 is rotated together with the guide roller 66c along with the rotation of the guide rollers 66a and 66b. The rotation direction is the counterclockwise direction in FIGS. 5 and 20 to 23.

Further, the drive shaft 70c is connected to the guide roller 6
The movable holding plate 72b is mounted on a movable holding plate 72b different from the fixed holding plate 72a to which the pivots 70a, 70b supporting 6a, 66b are mounted.
Guide roller 66 together with motor 71 and drive shaft 70c.
It is possible to move in the direction of arrow S in FIG. 22 (inside the separation and supply belt 67) approaching a and 66b and in the direction of arrow L in FIG. Then, when the guide rollers 66a, 66b, 66 are moved in the away direction which is the arrow L direction.
The separation / supply belt 67 stretched around the outside of c can be in a tightly tensioned state. On the contrary, when the separation / supply belt 67 is moved in the direction of the arrow S, the tension of the separation / supply belt 67 can be loosened. it can. In addition, the movable holding plate 72b
The position of the lock means 73 has the lock lever 73a.
It has a structure that can be locked so that it can be released. Therefore, the separation and supply unit 63 of the present embodiment
In this structure, when the lock by the locking means 73 is loosened and the guide roller 66c is moved to the inside of the separation supply belt 67 together with the movable holding plate 72b, the tension of the separation supply belt 67 is loosened, and the separation supply belt 67 can be easily replaced. Can be done. Further, since the guide roller 66c can be returned to the original state and locked together with the movable holding plate 72b after the replacement, the replacement work of the separation supply belt 67 and the like can be easily performed.

Incidentally, in the conventional separation / supply belt, the outer peripheral surface of the belt needs to be uneven in order to perform the reliable separation and feeding. Therefore, when a method of providing a tension roller on the outside of the belt and tensioning the belt toward the inside is used, the tension roller may be damaged because the outer peripheral surface of the belt is uneven. Further, an automatic tensioning mechanism using a spring has been constructed by making the tension roller movable, but there has been a problem that the spring itself is continuously loaded and the spring is damaged. Further, in the conventional belt replacement method, since the belt tension depends on the feeling of the operator after the replacement, there are problems that the values are not uniform and a special tool is required. However, in the structure of the present embodiment, the locking by the locking means 73 is loosened, and the movable holding plate 7
When the guide roller 66c is moved to the inside of the separation / supply belt 67 together with 2b, the tension of the separation / supply belt 67 is loosened, and the separation / supply belt 67 can be easily replaced. Further, since the guide roller 66c can be returned to the original state and locked together with the movable holding plate 72b after the replacement, the replacement work of the separation supply belt 67 and the like can be easily performed.

In the structure of this embodiment, the paper sheet 1
The guide rollers 66a and 66b forming the belt contact surface 67b facing the direction in which 0 is sent have a fixed structure after the position adjustment described later is performed together with the fixed holding plate 72. That is, the guide rollers 66a and 66b
Has a structure in which it does not move when the belt is replaced, so that the position where the belt contact surface 67a is arranged does not move even if the belt is replaced. If the position of the belt contact surface 67a at the paper sheet delivery position 8 shifts, the positional relationship between the arms 18a and 18b of the paper sheet transfer means 12 and the belt contact surface 67ba also needs to be adjusted again. In some cases, the work becomes complicated. However, since the structure of the present embodiment does not move when the belt is replaced, it can be secured in the same position and in the same state. Further, since the guide roller 66c is moved integrally with the motor 71, the drive shaft 70c, and the movable holding plate 52b, the motor 7 can be moved even if the guide roller 66c is moved.
1, the positional relationship between the drive shaft 70c is always secured, and there is no need to perform an operation (including reassembly) of the positional relationship between the motor 71 and the drive shaft 70c after replacement.

Furthermore, the separating and feeding belt 67 here is
The belt contact surface 67a is arranged at a right angle to the horizontal plane (bottom wall 11a) or slightly inclined (θ1) toward the insertion portion 11 side. The angle of the belt contact surface 67a is adjusted by rotating the fixed holding plate 72a, which holds the guide rollers 66a and 66b rotatably, clockwise or counterclockwise in FIG. 22, with respect to the bottom wall 11a. The angle can be adjusted arbitrarily. This angle adjustment is normally performed only once during manufacturing and assembly, and is fixed thereafter. In the structure of this embodiment, the belt contact surface 67b is perpendicular to the bottom wall 11a or the insertion portion 11b.
The reason for leaning forward to the side is that the weight (self-weight) of the succeeding paper sheet 10 that is sent following the preceding paper sheet 10 that is in contact with the belt contact surface 67a of the separation supply belt 67. Is added to the preceding paper sheet 10 to prevent the contact pressure between the preceding paper sheet 10 and the subsequent paper sheet 10 from occurring. That is, the preceding paper sheet 10 is attached to the belt contact surface 67a.
When held in a vertical (right angle) or forward tilted state, the weight of the succeeding paper sheet 10 is not added to the preceding paper sheet 10. Therefore, in the structure of the separating and supplying unit 63 of the present embodiment, the preceding paper sheet 10 is followed by the following paper sheet 1
Since the weight of 0 is added and the external force acting as a large contact pressure between the preceding paper sheet 10 and the following paper sheet 10 is eliminated, the preceding paper sheet 10 is separated and supplied. 67 allows smooth feeding. Further, it is possible to prevent the succeeding paper sheets 10 from being unaligned due to being dragged by the preceding paper sheets 10, and
When the sheet 10 is continuously fed, it is possible to avoid the sheet 10 from being fed in an unstable posture, and the sheet 10 can be smoothly fed without any trouble. The separation / supply belt 67 has a pair of front and rear suction windows 7 for vacuum suctioning the paper sheet 10.
Two paper sheet suction-holding portions 67b having the number 4 are provided by displacing by 180 degrees, and the sheets other than the suction window 74 are not breathable.

The vacuum suction means 68 of the separating / supplying portion 63 is located inside the separating / supplying belt 67 and has a belt contact surface 67.
The suction duct 75 is provided on the rear side of the a, and the suction duct 75 is connected to the vacuum pump 78. In addition, the suction duct 75 is the separation supply belt 6
7 is disposed at a position corresponding to the suction window 74 of the paper sheet suction holding portion 67b, and when the separation supply belt 67 is rotated and the suction window 74 does not reach the front of the suction duct 75, the suction port is separated. It is placed in a state of being blocked by the supply belt 67, and is opened when the suction window 74 reaches the front, and the suction duct 7 receives the suction force from the vacuum pump 78.
5. Air is sucked into the sheet 5, and at this time, the paper sheet suction holding unit 67
Paper sheet 10 that has been sent to a position adjacent to b,
The paper sheet suction-holding portion 67b is sucked in a state of being in close contact with the paper-sheet suction-holding portion 67b, and the suction port is closed again.
That is, the structure is such that the paper sheet 10 is vertically transferred to the paper sheet conveying means 4. The suction duct 75 is slenderly extended in the traveling direction of the separation / supply belt 67, and is sucked by the suction window 74 and moved upward together with the separation / supply belt 67. Reference numeral 10 is the transport belts 95a, 95 of the paper sheet transport means 4.
It is set so that it can be moved until it is sandwiched between b. Further, the separation / supply belt 67 does not always rotate, but normally, the paper sheet suction holding unit 67.
b is waiting at the origin position off the front surface of the suction duct 75, the front surface of the suction port of the suction duct 75 is blocked by the separation supply belt 67, and the paper sheet 10 is sent to the paper sheet feeding position 8. When it is detected by the sensor 93, the motor 71 is rotated, the separation supply belt 67 starts rotating, and when the separation supply belt 67 rotates 180 degrees and reaches the origin position, the rotation of the motor 71 is restarted. Then, the separation supply belt 67 also stops. Then, while the separation / supply belt 67 moves 180 degrees, the intake window 74 passes once in front of the intake duct 75, and the paper sheet 10 is delivered once. That is, one sheet of paper 10 is paid out each time it moves 180 degrees. In the present embodiment, the paper sheet suction holding unit 67b may be provided on the separating / supplying belt 67 once for every 180 degrees. Depending on the size of the separation / supply belt 67, three or more may be provided.

The three sensors 69a, 69b, 69c for the attitude defect detecting means 115 are reflection type sensors,
As shown in the schematic view of FIG. 27, the paper sheet A1 that is adsorbed by the separation / supply belt 67 and can be used in this paper sheet sorting apparatus.
Within the transport area 120 in which 0s are regularly delivered, they are arranged in a portion of substantially the maximum width, which is scattered along the transport direction. In the attitude defect detecting means 115 using the sensors 69a to 69c, when the three sensors 69a to 69c detect the same position at the same time as the paper sheet A10 shown by the solid line in FIG. Judge that it has become. On the other hand, like the paper sheet A10 shown by the one-dot chain line or the paper sheet A10 shown by the two-dot chain line, it falls or tilts and only one sensor 69a among the three sensors 69a to 69c (one point In the case of the paper sheet A10 indicated by the chain line) or when only two sensors 69a and 69b (in the case of the paper sheet A10 indicated by the two-dot chain line) are detected,
It is determined that the paper sheet A10 has been fed out in a poor posture, the posture failure detection means 115 sends output information to the system control unit 100 (FIG. 28) described later, and the system control unit 100 issues a warning or the like. At the same time, the device is stopped to prompt the operator to perform the process. As a result, it is possible to prevent the paper sheet 10 from being fed out of the separating / supplying unit 63 in a posture-improper state.

The separation assisting section 64 is provided below the separating and supplying section 63, and serves as an auxiliary contact surface which is opened toward the direction in which the sheet transporting means 12 conveys the sheet. It has a housing 81 provided with an auxiliary suction window 80 (hereinafter, this portion is referred to as "auxiliary contact surface 80"), and an intake port of a suction duct 84a as an auxiliary vacuum suction means 84 is provided in this housing 81. . Suction duct 84
a uses the same vacuum pump 78 as the suction duct 75 of the vacuum suction means 68 as the suction source.
The intake air is divided into two parts, that is, an intake passage toward the suction duct 75 side and an intake passage toward the suction duct 84a side. The suction duct 84a is provided with a negative pressure gauge 87 for measuring the negative pressure in the suction duct 84a. Further, regarding the relationship between the suction area of the suction duct 84a in the auxiliary suction means 84 and the suction area of the suction duct 75 in the vacuum suction means 68, the suction area of the suction duct 84a in the auxiliary suction means 84 is set larger. Further, the auxiliary contact surface 80 is not linearly aligned with the belt contact surface 67a of the separation and supply belt 67, but the lower side thereof slightly projects toward the insertion portion 11 side, and the contact portion 67a and the auxiliary contact surface 8 are formed.
The connection with 0 is arranged in the shape of an approximate "C". In addition, as shown in the detailed structure in FIGS. 24 to 26, a breathable net 82 is attached to the front surface of the auxiliary contact surface 80 so as to cover the front surface thereof. A frame body 83 having a U-shape is attached to the outside. The frame body 83 has a concave-convex portion formed outside the auxiliary contact surface 80. The frame body 83 is convex, and the inside surrounded by the frame body 83 is concave. In addition, the lower end of the frame 83 has the auxiliary contact surface 8
It is provided so as not to cover the lower part 83a of 0.

When the paper sheet 10 is sent to the paper sheet feeding position 8, the lower end portion of the paper sheet 10 is vacuum-sucked by the suction duct 84a, and the lower end portion of the paper sheet 10 is assisted. While being adsorbed on the contact surface 80, the suction port of the suction duct 84a is blocked by this adsorption. In this suction, the lower end portion of the paper sheet 10 warps as shown in FIGS. 24 to 26. This will be described in more detail. FIG. 24 is an exploded perspective view of an essential part in a state where the lower end portion of the paper sheet 10 is adsorbed by the auxiliary contact surface 80, and FIG. 25 is a sectional view taken along line BB of FIG. FIG. 26 is a sectional view taken along the line CC in FIG. 24.
In FIGS. 24 to 26, the suction here is performed as shown in FIGS. 24 to 26 because the convex portions formed by the frame body 83 are formed at both ends (front and rear) and the upper portion of the auxiliary contact surface 80. The central portion of the paper sheet 10 projects toward the auxiliary contact surface 80 side, and both ends of the paper sheet 10 project toward the subsequent paper sheet 10 side. Made In this case, the lower end portion 80a of the auxiliary contact surface 80 has a flat surface without the arrangement of the frame body 83, and thus the lowermost portion of the paper sheet 10 corresponding to this portion 80 is located. The part forms a flat part 10a. When the flat portion 10a is formed below the arched portion in this manner, a gap 88 formed between the flat portion 10a and the succeeding paper sheet 10 is formed.
Becomes larger, and air for peeling, which will be described later, is added to the gap 88. Therefore, in the structure of the portion of the auxiliary contact surface 80 configured in this way, the sheet feeding position 8
When the lower end portion of the paper sheet 10 sent to the device is attracted to the auxiliary contact surface 80 and a warp is created at the lower end portion, the succeeding paper sheets are overlapped and sent. If it is coming, it can be peeled off by warping, and for the succeeding paper sheet 10 that came later, a gap 88 (see FIG. 25, FIG. 26) is created between them by the warping, It can be left unattached. At the same time, the auxiliary contact surface 80 and the belt contact surface 67a of the separation / supply belt 67 are connected.
Since a portion 96 (see FIGS. 20 to 26 and 30) between and is provided with an angle of a V-shape, the paper sheet 10 adsorbed on the auxiliary contact surface 80 is supplemented by the auxiliary contact surface 80. It is bent between the contact surface 80 and the belt contact surface 67a, and as shown schematically in FIGS. 25 and 30, a gap is also formed between the bent portion 96 and the succeeding paper sheet 10. It will be.

In addition, in the separation assisting portion 64, a blower duct 85 for blowing air toward the gap 88 is arranged below the gap 88 corresponding to the portion where the gap 88 is formed.
Then, the air from the blowing duct 85 blown out is applied to the gap 88 from the lower side, and the air is positively separated between the paper sheets 10 to separate and supply only the first sheet. The belt 67 is held and sent. Further, since the flat portion 10a is provided at the lower end portion of the paper sheet 10 that is in contact with the auxiliary contact surface 80, and a large opening for blowing air is secured, the blower duct 8
A large amount of air from 5 is received by the gap 88, and the succeeding paper sheet 10 is peeled off conveniently. In addition, the ventilation duct 8
5 is connected to a blower 90 via a valve 89.

The paper sheet detection means 106 and the paper sheet over-push detection means 105 are arranged below the separation assisting portion 64, and inside the feeding portion 11 in the direction in which the paper sheet 10 is conveyed. Has a contactor 92 extending to the rear, and a paper sheet detection sensor 93 for the paper sheet detection means 106 behind the contactor 92.
And an overpush detection sensor 94 for the paper sheet overpush detection means 105 is provided. Further, a part of the contactor 92 is provided with a light blocking plate 92a for the paper sheet detection sensor and a light blocking plate 92b for the overpush detection sensor. Then, the contactor 92 is largely protruded into the insertion portion 11 when the paper sheet 10 is not conveyed to the paper sheet feeding position 8 and the light shielding plates 92a and 92b are provided with the paper sheet detection sensor 9.
3 and the over-push detection sensor 94 are arranged at positions separated from each other. The paper sheet 10 is moved to the paper sheet delivery position 8 by the paper sheet transfer means 12 and the second paper sheet transfer means 16.
When the paper sheet 10 is conveyed to the paper sheet and is pushed by the paper sheet 10, the contactor 92 retracts, and the light shielding plate 92a is first moved to the paper sheet detection sensor 9
The paper sheet detection sensor 9 indicates that the paper sheet 10 has been transferred to the paper sheet feeding position 8 by entering the inside of the paper sheet 3.
3 and a signal is sent to the paper sheet detection means 106 (see FIG. 28), and the paper sheet detection means 106 can detect the presence or absence of the paper sheet 10. And paper sheets 1
When the feeding of 0 is proper and the paper sheet 10 is not pushed too far toward the separating and feeding belt 67 side, the contactor 92 does not retreat beyond this state. When the paper sheets 10 are fed one after another and jammed and jammed, the contactor 92 is further retracted and the light shielding plate 92b is pushed into the over-pressing detection sensor 94, whereby the paper sheets 10 are pushed. Is pushed too much by the over-push detection sensor 94, and a signal is sent to the over-push detection means 105 (see FIG. 28), and the over-push detection means 105 pushes the paper sheet 10 too much. It has a structure that can detect that

(Structure on Paper Sheet Conveying Means Side) The paper sheet conveying means 4 is arranged adjacent to the belt contact surface 67a of the separating and feeding belt 67 and facing each other on the drive system side. Means 95a and driven belt side conveyor belt means 95b
have. The paper sheet conveying means 4 draws the paper sheet 10 fed out in the vertical direction by the separation supply belt 67 between the drive system side conveyance belt means 95a and the driven system side conveyance belt means 95b, and The sheet 10 is conveyed to the sorting stacker 3a side through the reading unit 2 by the drive system side transport belt unit 95a and the driven system side transport belt unit 95b.

Further, inside the conveyor belt means 95b,
It is fed out by the separation supply belt 67, and is conveyed by the conveyor belt means 9
A thickness detection sensor 79 for the paper sheet thickness detection means 113 (see FIG. 28) for detecting the thickness of the paper sheet 10 passing between 5a and 95b is arranged. The thickness detection sensor 79 is a reflection type sensor, and is the conveyor belt means 95.
When the paper sheet 10 passes between a and 95b, it sends a signal to the paper sheet thickness detecting means 113 according to the amount of swelling of the belt of the conveyor belt means 95b. Paper thickness detecting means 1
At 13, the thickness of the paper sheet is detected from the output information of the thickness detection sensor 79, and the information is sent to the system control unit 100. In the system control unit 100, the paper sheet thickness detecting means 1
Based on the information from 13, the optimum speed for the paper sheet transfer means 12 and the second paper sheet transfer means 16 to continuously feed toward the paper sheet delivery position 8 is calculated, and feedback control is performed. Here, for example, a paper sheet 10 having a large thickness
When the paper is fed by the separating and feeding belt 67 and when the thin paper sheet 10 is fed, a gap formed between the succeeding paper sheet 10 and the belt contact surface 67a at the paper sheet feeding position 8. Is different. That is, among the paper sheets being transferred, there are paper sheets of any thickness, including thick ones and thin ones. Therefore, it is necessary to control the transfer speed of the paper sheet transfer means 12 that feeds the separated paper sheet into the separating and supplying unit by the thickness of the delivered paper sheet. If the paper sheet transfer means 12 feeds the paper sheet 10 at a constant speed without looking at the thickness information, the feeding speed of the thinnest paper sheet 10 must be unified in order to prevent over-pressing. Then, when a thick paper sheet is fed, a wasteful time is generated for feeding for several seconds thereafter. In order to speed up the processing capacity of the machine, the thickness of the paper sheet immediately after being fed out is detected, and the thickness information is reflected in the control of the paper sheet transfer means. Therefore, in the structure of the present embodiment, the thickness of the paper sheet immediately after being fed out is detected, and the thickness information is reflected in the control of the paper sheet transfer means. The speed can be increased.

(Control Operation of Main Part) FIG. 29 is a flowchart showing the operation of the main part of the paper sheet supply unit in the paper sheet sorting system. Therefore, the operation of the paper sheet supply process in the present embodiment will be described next according to the flow of FIG. First, prior to the description of the operation, in the structure of the present embodiment, the suction source of the suction duct 75 (vacuum suction means 68) on the separation supply unit 63 side and the suction duct 84 on the separation auxiliary unit 64 side.
The suction source of a (auxiliary suction means 84) has a structure in which it is covered by the same single supply source. The principle of operation in this structural portion will be described first. In this structure, the suction duct 75 and the suction duct 84a are the same suction source (vacuum pump 7
The suction from 8) is bifurcated in the middle, and when the suction duct 75 and the suction duct 84a are not closed, the intake block internal pressures are in equilibrium and equal. Even when there is a change in the environment such as closing or opening in either one, the internal pressures of the two transition to the equilibrium state, that is, the same pressure in a moment, although the values are different from before. When the intake port is open on either side, a large amount of air is supplied for vacuuming the open intake port, so the vacuuming effect is neutralized and the internal pressure is kept low. Both are in equilibrium. This is called leak, atmospheric pressure release, etc.

Therefore, the paper sheet 1 is placed at the paper sheet feeding position 8.
Separation and supply belt 6 arrived from the state where 0 has not arrived
Looking at the operation until it is fed toward the paper sheet conveying means 4 in 7, the operations are performed in the order of (1) to (4). The separating / supplying belt 67 in the separating / supplying unit 63 holds the sheet by suction until the sheet 10 is detected at the sheet feeding position 8 by the sheet detecting unit 92 or the negative pressure detecting unit 109. The position of the origin where the suction window 74 of the portion 67b is separated from the front surface of the suction duct 75, and the suction port of the suction duct 75 is blocked by the portion of the separation supply belt 67 other than the suction window 75 (hereinafter referred to as this The position is simply called "origin position")
It is located in. (1) First, when the sheet 10 has not arrived at the sheet feeding position 8 and the suction duct 75 is on standby with the suction port closed by the separation belt 67, the suction duct 84a Since the atmosphere is released in, the internal pressures of both are in equilibrium with a small value. Therefore, an excessive load is not applied to the vacuum pump 78 that is the suction source. (2) When the paper sheet 10 is sent to the paper sheet delivery position 8 and the paper sheet 10 abuts on the auxiliary contact surface 80, both are in a sealed state, so that the internal pressure of both is large. The value is in equilibrium. Subsequently, when the separation / supply belt 67 is rotated and the suction window 74 of the paper sheet suction holding portion 67 corresponds to the paper sheet 10 in front of the intake duct 75, the paper sheet 10 is sucked by the intake window 74 and sucked. The front surface of the duct 75 is kept closed. Here, the suction duct 84 in the auxiliary suction means 84
Since the suction inlet area of the suction duct 75 in the vacuum suction means 68 is formed larger than the suction inlet area of a,
When the separation / supply belt 67 is rotated, vacuum suction means 68
Due to the large suction force generated by the (intake duct 75), the preceding sheet 10 is drawn out while being sucked into the suction window 74. ((Adsorption force) = (Suction port internal pressure) x (Suction port area)). (3) Further, since the preceding paper sheet 10 is adsorbed by the vacuum suction means 68 (intake duct 75) to the separating / supplying belt 67 and fed out, when the separation from the bundle of paper sheets 10 is started, the auxiliary suction means is provided. Since the closed state of the intake duct 84a in 84 is released, a slight atmospheric pressure release occurs,
Internal pressure decreases. Therefore, the work of separating the preceding paper sheet 10 from the suction force of the auxiliary suction means 84 is smoothly performed. (4) Immediately after that, the succeeding paper sheet 10 sent by the paper sheet transfer means 12 and the transfer belt means 43A and 43B of the second paper sheet transfer means 16 and the auxiliary transfer belt means 44A and 44B. Contacts the auxiliary contact surface 80. Therefore, both are in a sealed state, and the internal pressures of both are large and are in equilibrium. As a result, the succeeding paper sheets attracted by the suction duct 84a are held (held) at unstable timing so as not to be taken out, and the preceding paper sheet 10 about to be taken out is separated and supplied with a great force. Done. That is, the sheet 10 is used to substantially open and close the valve to control it.

Then, when a plurality of paper sheets 10 are put together in a bundle at the input section 11 of the paper sheet supply section 1, the partition arm section 19 and the partition arm section 19 are in an upright position.
It is divided into two parts and put in and set. This is the arm (18a, 18b and 18a, 18b) of the partition arm part 19.
Supported by both sides. At the sheet feeding position 8, the sheet 10 is detected by the sheet detecting means 92 or the negative pressure detecting means 10.
9 is not detected, the paper sheet transfer means 12 and the second
Transfer belt means 43A, 43B of the paper sheet transfer means 16
And the auxiliary transfer belt means 44A and 44B are respectively moved faster than usual, and the paper sheet 10 loaded in the input section 11 is aligned while being aligned by the vibration of the paper sheet vibrating means 15. The transfer means 12 and the transfer belt means 43A and 43B of the second paper sheet transfer means 16 and the auxiliary transfer belt means 44A and 44B are fast-forwarded to the paper sheet feeding position 13 while standing. When the paper sheet 10 is fast-forwarded to the paper sheet delivery position 8 and the paper sheet 10 is detected by the paper sheet detection means 92 or the negative pressure detection means 109, thereafter, the paper sheet transfer means 12 and the second paper sheet transfer. Transfer belt means 43A, 43B of means 16 and auxiliary transfer belt means 4
The speeds of 4A and 44B are synchronized with the sheet feeding operation in the separating and supplying section 63.

On the other hand, on the separation / supply belt 67 in the separation / supply unit 63, as described above, the paper sheet 10 arrives at the paper sheet feeding position 8 and is detected by the paper sheet detection means 92 or the negative pressure detection means 109. Until that time, it is arranged at the origin position and the output of the vacuum pump 78 is suppressed (low speed operation). As described above, when vacuum suction is not actually required, unnecessary output can be reduced and power consumption can be suppressed by suppressing the output of the vacuum pump 78. At the same time, the life of the vacuum pump 78 can be extended. Therefore, here, while the suction in the suction duct 75 is not required, the suction force on the suction duct 84 side is not reduced to reduce noise and waste power consumption, and extend the life of the vacuum pump 78. You can Then, when the paper sheet 10 arrives at the paper sheet delivery position 8 and is detected by the paper sheet detection means 92, the output suppression of the vacuum pump 78 is released and the normal operation is resumed.
On the other hand, when it is detected by the negative pressure detection means 109, both the intake port of the intake duct 75 and the intake port of the intake duct 84a have already been closed, and the internal pressure is already high, so the vacuum pump The separation / supply belt 67 is rotated while 78 is suppressed (low speed operation), and the sheet 10 is fed out.

The control thereafter is carried out when the paper sheet 10 sent to the feeding position is detected by the paper sheet detecting means 106 (pattern A) and is detected by the paper sheet detecting means 106. However, the processing when the paper sheet over-pressing detection means detects too much (pattern B) and the paper-sheet detection means 106 does not detect, but the negative pressure gauge 87 presents a negative pressure value equal to or more than the specified value. Processing (pattern C) when the negative pressure is detected by the negative pressure detecting means 109. The processing in each of the patterns A, B and C will be described below.

(Pattern A) When the paper sheet 10 is sent to the paper sheet feeding position 8 and hits the contactor 92, the contactor 92 retracts and the light shielding plate 92a enters into the sensor 93. The paper sheet 1 is detected by the paper sheet detection unit 106 from the output information.
It can be seen that 0 has been transferred to the sheet feeding position 8. When the paper sheet detecting means 106 detects the paper sheet 10, the transfer by the transfer belt means 43A, 43B of the paper sheet transfer means 12 and the second paper sheet transfer means 16 and the auxiliary transfer belt means 44A, 44B. The speed due to the transfer by means of is returned to the normal speed synchronized with the feeding operation of the paper sheet 10 by the separating and supplying belt 67. At the same time, the suppression of the operation of the vacuum pump 78 is released. And
The separating / supplying belt 67 is rotated, and the paper sheet adsorbing and holding unit 67b adsorbs and holds the paper sheet 10 on the way, and the paper sheet conveying means 4
Of the conveyor belt means 95a and 95b. Then, the belt means 95a of the paper sheet conveying means 4,
The thickness of the paper sheet 10 passing between the paper sheet 95b and the sheet 95b is detected from the output information obtained by the paper sheet thickness detection sensor 79,
In accordance with this thickness, the system control unit 100 corrects the transfer speed of the transfer belt means 43A and 43B of the paper sheet transfer means 12 and the second paper sheet transfer means 16, that is, executes the above feedback control, and separates the supply belt. Feeding by 67, paper sheet transfer means 12 and second paper sheet transfer means 1
6 is synchronized with the feeding by the transfer belt means 43A and 43B. When the separating and feeding belt 67 fails to feed the paper sheet 10, the transfer belt means 43 of the paper sheet transfer means 12 and the second paper sheet transfer means 16 is used.
A and 43B are stopped, and auxiliary transfer belt means 4
4A, 44B fast reverse for a certain period of time,
The paper sheet 10 is once separated from the belt contact surface 67 a, and the separating / supplying belt 67 is caused to perform the feeding operation again. If this feeding operation fails several times, an alarm is issued and the operator is instructed to perform necessary processing.

(Pattern B) At the paper sheet feeding position, the contact 92 is pushed by the paper sheet 10 more than necessary, and the light shielding plate 92b is formed.
When the paper sheet 10 enters the sensor 94, the overpush detection unit 105 detects from the output information that the paper sheet 10 is pushed more than necessary at the paper sheet feeding position 8. Then, the system control unit 100 causes the transfer belt means 43A, 43 of the paper sheet transfer means 12 and the second paper sheet transfer means 16.
While the transfer by B and the transfer by the auxiliary transfer belt means 44A, 44B are stopped, the feeding operation of the paper sheet 10 by the separation supply belt 67 is performed. Here, when the feeding of the paper sheet 10 by the separation supply belt 67 is successful,
Similar to the case of the pattern A, the paper sheet 10 is sent between the transport belt means 95a and 95b, and the thickness is detected by the paper sheet thickness detection sensor 79 and is sent to the downstream side. On the other hand, when the feeding operation of the paper sheet 10 by the separation supply belt 67 fails, the transfer belt means 43A, 43 of the paper sheet transfer means 12 and the second paper sheet transfer means 16.
With B stopped, auxiliary transfer belt means 44A, 44B
The fast feed reverse rotation is performed for a certain period of time, the paper sheet 10 is once separated from the belt contact surface 67a, and the feeding operation by the separation supply belt 67 is performed again. If this feeding operation fails several times, an alarm is issued and the operator is instructed to perform necessary processing.

(Pattern C) Even if the paper sheet 10 is sent to the paper sheet feeding position 8, the paper sheet 10 is slightly displaced and does not hit the contactor 92, and the paper sheet detecting means 106 detects the paper sheet. If the type 10 is not detected, but the sent sheet 10 is brought into contact with the portion of the auxiliary contact surface 80, the negative pressure in the suction duct 84a of the separation assisting portion 64 is equal to or higher than the specified value. become. Therefore, when the negative pressure obtained from the negative pressure gauge 87 is equal to or less than the specified value, it is determined that the paper sheet 10 has not been sent to the paper sheet feeding position 8, and the standby state is set. On the other hand, when the negative pressure exceeds a specified value, it is determined that the paper sheet 10 has been sent, and the transfer belt means 43A of the paper sheet transfer means 12 and the second paper sheet transfer means 16 is sent. , 43B and the transfer by the auxiliary transfer belt means 44A, 44B are stopped, the feeding of the paper sheet 10 by the separation supply belt 67 is performed, and thereafter, as in the case of the pattern A, the paper sheet 10 is fed. Is conveyed between the conveyor belt means 95a and 95b, and the thickness is detected by the paper sheet thickness detection sensor 79 on the way, and is conveyed to the downstream side. Other operations are the same as those of the pattern A.

In the structure of the above embodiment, a pair of arms 18a, 18b are used, and each arm 18a, 18b
The slits 14a and 14b for moving 18b
Although the case where it is formed between the middle and lower three back plates 13a to 13c has been described, the case may be one arm or three or more arms. If only one is used, the back plate is made up of two plates,
When the number is three or more, it is formed by four or more plates.
