Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet processing apparatus for detecting the characteristics of sheets and stacking them by type by aligning the front and back and top and bottom, and in particular, by denomination by aligning the front and back and top and bottom of bills. The present invention relates to a deposit processing machine that is accumulated in a company.

[0002]

2. Description of the Related Art Conventionally, as a sheet processing apparatus, for example,
Banknotes of multiple denominations are mixed and inserted at once, the inserted banknotes are taken out one by one on the transport path, their characteristics are detected, and their front and back and top and bottom are aligned and denominated,
2. Description of the Related Art There has been known a depositing machine that seals banknotes of the same denomination every predetermined number of sheets.

[0003]

In the above-described conventional depositing machine, the attitude of the banknotes taken out on the transport path is such that the banknote is inclined relative to the transport path (skew) and / or in the width direction of the transport path. If you are in a one-sided position (shift)
The following various problems occur.

[0004] First, when the skew and shift of a banknote taken out on the transport path exceed an allowable amount, the banknote is determined to be unprocessable and rejected. If the degree of skew and shift increases, the banknote is rejected. However, there has been a problem that the rate of operation increases and the operation rate of the apparatus decreases. For this reason, the operator has arranged to insert bills in a bank.

[0005] Second, in the detection unit for detecting the characteristics of the bill, it is necessary to increase the margin of the detection width in consideration of the shift of the bill passing through the detection unit. However, there was a problem that the size was increased in the width direction.

Third, when the bill is skewed or shifted when the bill is conveyed in the reverse direction as required, if the bill is skewed or shifted, the bill cannot be normally switched back. There was a problem of jamming at the back.

[0007] Fourth, if the banknote is shifted as needed when the banknote is turned over, not only the banknote after the turnover is shifted but also if the shift exceeds the allowable amount. In some cases, bills may fall off the conveyor belt.

Fifthly, when a banknote is skewed when a plurality of gates disposed on the transport path are switched to switch the transport direction of the banknote, the transport gap between two consecutive banknotes is kept constant. However, there is a case where the transport gap becomes short and the switching of the gate cannot be made in time, and there is a problem that a jam occurs.

Sixth, in a stacking unit for stacking banknotes by denomination, if the banknotes fed to the stacking unit are skewed or shifted, the stacking state of the banknotes in the stacking unit becomes unstable. .

[0010] Seventh, in a banding section for banding a banknote of the same denomination every predetermined number, when a banknote with skew or shift is sent to the banding section, the banknotes in which the accumulation state is unstable are kept. However, there is a problem that the sealing state becomes unstable.

And

A drive shaft 35 extends between the two side plates 34b, 34b via bearings 36, 36.
Two rollers 37, 37 are attached to the drive shaft 35. The outer peripheral surfaces of these two rollers 37, 37 are formed of a rubber material in order to increase the frictional force. Above these two rubber rollers 37, 37,
Two corresponding rubber rollers 38 are in rolling contact with each other. The two rubber rollers 38 are attached to a shaft 40 via a bearing 39. Both ends of the shaft 40 are fitted into elongated holes 41 formed in the side plates 34b, 34b of the support frame 34, and are urged downward by springs 42 provided outside the side plates 34b, 34b. That is, the two rubber rollers 38, 38 are pressed by the corresponding two rubber rollers 37, 37, respectively, and these four rubber rollers 37, 38 function as the correction rollers 37, 38.

The correction rollers 37 and 38 are connected to three pairs of transport belts 4 extending through the attitude correction device 10 along the transport path 6.
Nested between 9a, 49b, 49c. That is, a pair of rollers 37, 38 on the front side of the apparatus.
Is disposed between the first and second conveyor belt pairs 49a and 49b, and the roller pair 37 and 38 on the rear side of the apparatus

Is mounted inside a pulley 45 fixed to the cylindrical shaft 43. In addition, a pulley 64 is attached near the lower end of the drive shaft 44 via a one-way clutch 55. The rotating shaft of the stepping motor 54 is connected to the pulley 64 via a belt 62 and a pulley 63.

When the stepping motor 54 is driven to rotate, the pulley 63, the belt 62, and the pulley 6
The driving force is transmitted through the drive shaft 4 and the drive shaft 44 is rotated. The drive shaft 44 rotates only in one direction by the action of the one-way clutch 55. When the drive shaft 44 rotates in a predetermined direction, the bevel gear 51 attached to the upper end rotates, and the drive shaft 35 is rotated via the bevel gear 50. When the drive shaft 35 is rotated, the two rubber rollers 37, 37 are rotated, and the two rubber rollers 38, 38 pressed and rolled by the two rubber rollers 37, 37 are also driven to rotate. Thus, the four correction rollers 37, 3
When the roller 8 rotates, the banknote P is clamped in the two nips between the rollers and is conveyed along the conveyance path 6. The strength of the spring 42 is set such that the clamping force of the banknotes P by the correction rollers 37 and 38 of the posture correction device 10 is stronger than the clamping force of the banknotes P by the transport belts 49a to 49c.

On the other hand, the cylindrical shaft 43 is

The directions of 7, 38 are variable. The amount of rotation of the support frame 34 is adjusted by controlling the number of steps of the stepping motor 48 with the time when the sensor 59 detects the object 60 as the home position.

Next, the attitude correction operation of the banknote P by the attitude correction apparatus 10 configured as described above will be described with reference to FIG.

The banknotes P taken out from the input section 5 onto the transport path 6 are transported while being pinched and restrained by the first to third transport belt pairs 49a to 49c. Passed sequentially. Here, it is assumed that a skew θ1 and a shift ΔS of a degree indicated by the solid line in FIG.

As shown in FIG. 4, when the banknote P is fed into the attitude correction device 10, the stepping motor 54 of the first correction unit 32 is driven, and the correction rollers 37 and 38 rotate around the conveyor belt pairs 49a to 49c. It is rotated at a peripheral speed equal to the speed.

At this time, the conveying posture of the banknote P fed into the posture correcting device 10 is detected via the optical sensor array 70 disposed upstream of the first correcting unit 32 in the conveying direction. The optical sensor array 70 has a plurality of light-emitting portions and light-receiving portions (not shown) each having an optical axis passing through the transport path 6 in the vertical direction. A plurality of light emitting units and light receiving units are arranged so as to be arranged in a direction perpendicular to the direction.

Then, based on the result of detection by the optical sensor array 70, the size of the bill P, the amount of positional deviation of the center of the bill P from the center line 6a of the transport path 6 in the width direction,
That is, the shift amount ΔS [mm], and the angular deviation amount in which the longitudinal side of the bill P is displaced from the width direction orthogonal to the transport direction T, that is, the skew angle θ1
[°] is calculated.

At this time, if it is determined based on the detection result that the length of the paper money P in the longitudinal direction is shorter than the kind of paper money that can be processed by the apparatus, the paper money P is inserted into a folded paper or a folded paper. It is determined that the bill is a broken one, and the posture correction for the bill P is not performed.
To eliminate.

Next, assuming that the width of the banknote P is L [mm], θ2 that tan θ2 = Δs / L is calculated. Then, the second stepping motor 48 is rotationally driven so as to rotate the first correction unit 32 by the angle θ2 as shown by an arrow 71 in FIG. At this time, the first
Although the cylindrical shaft 43 and the shaft 44 of the correction unit 32 rotate in the opposite direction, the rotation speed of the first correction unit 32 does not change because the one-way clutch 55 idles.

In this state, when the bill P is sent to the first correction section 32, the bill P is conveyed while being pinched and restrained by the correction rollers 37 and 38. Correction roller 37,
The banknote P conveyed by the transport path 38
It is directed in a direction T ′ shifted by θ2 with respect to a. At this time, the banknote P is directed in the direction of the arrow T ′ while maintaining the skew angle θ1, and the displacement in the width direction is corrected.

Next, at the timing when the front end of the bill P has passed the sensor 72, that is, immediately after the bill P is pinched and restrained by the correction rollers 37 and 38 of the second correction unit 33, the second correction is performed. The part 33 is indicated by an arrow 73 in FIG.
Rotate in the direction of. Thus, the correction rollers 37, 3
8 clamps the banknote P in the second correction unit 3
By rotating the skew, the skew of the banknote P is corrected.

Through the above-described series of control operations, the shift and skew of the banknote P are continuously corrected, and the banknote P is conveyed to the downstream detection unit 7 as a corrected banknote P in the correct posture. In addition, among the bills P sent to the posture correction device 10, the bills P originally without skew and shift are
By not rotating the first and second correction units 32 and 33, the sheet is conveyed to the immediately following detection unit 7 while maintaining the correct posture. In the present embodiment, the correct posture is a posture in which one end side along the longitudinal direction of the bill P is orthogonal to the center line 6a of the transport path 6 and the center of the bill P is located on the center line 6a. To tell.

As described above, according to the present invention, the charging section 5
Since the posture correction device 10 is disposed on the conveyance path 6 immediately after,
The following effects are produced in various processing units disposed downstream of the posture correction device 10 in the transport direction. In other words, in the present invention, the posture correction device 10 includes the detection unit 7, the switchback mechanism 8, the front / back inversion mechanism 12, and the accumulation unit 15 a.
~ 15f, sealing processing unit 4, and gates G1 ~ G9,
Since the paper money P is arranged on the upstream side in the transport direction, the following effects can be obtained.

First, since the posture correcting device 10 is disposed on the transport path 6 immediately after the loading section 5, the rejection rate of the banknote P can be reduced, and the operation rate of the deposit processing machine 1 can be increased. Also,
The bill P can be inserted into the insertion section 5 without concern for the posture of the bill P, and the operability by the operator can be improved.

That is, the posture correction device 10
By providing the banknotes P, even if the banknotes P are inserted in different postures, the conveyance posture of the banknotes P can be corrected to a correct posture immediately after being taken out, so that the rejection rate due to the conveyance failure of the banknotes P can be suppressed low. The operating rate of the depositing machine 1 can be improved. In addition, since the posture correction device 10 is disposed immediately after the insertion unit 5, the operator can insert the banknotes P into the insertion unit 5 without worrying about the posture at the time of insertion of the banknotes P, thereby improving the operability by the operator. Can be improved.

Conversely, when the posture correcting device 10 is not provided on the transport path 6 immediately after the loading section 5, for example, as shown in FIG. 5, the skewed banknote P2 and the shifted banknote P3
Is transported to the subsequent processing section in the same posture. In this case, if the skew or shift exceeds the permissible amount, the banknote will be rejected to the reject unit 11, and a large amount of banknotes P will be rejected to the reject unit 11 and the reject rate will increase. Can be When the rejection rate increases, the operation rate of the deposit processing machine 1 decreases. For this reason, in the present invention, the posture correcting device 10 is disposed immediately after the insertion unit 5, and the banknote P corrected to the correct posture is conveyed to the subsequent processing unit as shown in FIG.

Second, the posture correction device 1 is provided immediately before the detection unit 7.
Since 0 is provided, the banknote P can always be sent to the detection unit 7 in a state where the banknote P is conveyed to the correct posture.
In particular, in the present embodiment, the transport posture of the banknote P is corrected so that the center of the banknote P is located on the center line 6a of the transport path 6. For this reason, for example, as compared with the case where the attitude correction device 10 is not provided before the detection unit 7 (detection width W ′) as shown in FIG. 6a.
As shown in FIG. 8, the detection width W of the banknote P in the detection unit 7
Can be narrowed. Thus, the length of the detection unit 7 in the width direction can be reduced, the size of the detection unit 7 can be reduced, and the configuration of the detection unit 7 can be simplified.

Conversely, before the detection unit 7,
Is not provided (FIG. 7), it is necessary to set the detection width W 'in consideration of the shifted banknote P2, so that it is necessary to increase the detection width margin.

More specifically, for example, in FIGS.
In the example shown in FIG. 7, when the posture correction device 10 is not provided (FIG.
), It is necessary to arrange the four sensors 7a to 7d side by side in the width direction. On the other hand, if the posture correction device 10 is arranged immediately before the detection unit 7 (in the case of FIG. Sensor 7
What is necessary is just to arrange a-7c side by side in the width direction, and one sensor can be omitted.

Further, by feeding the banknote P whose transporting posture has been corrected to the correct posture to the detection unit 7, the detection accuracy of the banknote P in the detection unit 7 can be improved, and the rejection rate of the banknote P due to the detection failure can be reduced. It can be kept low. That is, in the example as shown in FIG. 7 without the attitude correction device 10, the banknote P having a skew or a shift is detected by the detection unit 7.
If the skew or shift exceeds the allowable amount, the banknote P becomes undetectable and is rejected, so that the transport posture of the banknote P is correct as in the present invention. By correcting the posture and then sending it to the detection unit 7, it is possible to prevent undetectability due to poor posture and reduce the rejection rate of the banknote P.

Third, since the posture correcting device 10 is disposed on the upstream side of the switchback mechanism 8 in the conveying direction, the banknote P can always be sent to the switchback mechanism 8 in a state where the conveying posture of the banknote P is corrected to the correct posture. . Therefore, the reverse operation of the banknote P in the switchback mechanism 8 can always be performed stably, and the banknote P
Jam can be prevented.

Conversely, if the attitude correcting device 10 is not provided upstream of the switchback mechanism 8, the skewed and shifted banknotes P will be sent to the switchback mechanism 8, and a jam will easily occur. For this reason, in the present invention, the posture correction device 10 is disposed upstream of the switchback mechanism 8.

Fourthly, since the posture correction device 10 is disposed on the upstream side in the transport direction from the front / back reversing mechanism 12, the bill P
Can be sent to the front / back inverting mechanism 12 in a state in which the transporting posture of the camera has been corrected to a correct posture. For this reason, as shown in FIG. 9, the banknote Pf sent in the correct posture without shift so that the center thereof coincides with the center line of the torsional transport path 12a of the front / back reversing mechanism 12 passes through the torsional transport path 12a. Thereafter, the bill is sent out as a bill Pr in a correct position, the center of which is located on the center line of the transport path. This makes it possible to stabilize the transporting posture of the banknote Pr after turning over, and also to prevent a problem that the banknote P falls off from the transporting path 6 due to the defective posture.

Conversely, when the attitude correcting device 10 is not provided upstream of the front / back inversion mechanism 12, there is a possibility that the shifted banknote Pf is fed into the front / back inversion mechanism 12, as shown in FIG. , In this case, the banknote P after turning over
r also remains shifted. In this case, the banknotes P that have been shifted are conveyed to the processing unit at the subsequent stage, which causes a further problem. Further, if the shift of the banknote Pf sent to the front / back reversing mechanism 12 exceeds a certain amount, in the worst case, the banknote P may be detached from the belt and fall off the transport path 6. For this reason,
In the present invention, the posture correction device 10 is disposed upstream of the front / back inversion mechanism 12.

Fifthly, since the attitude correcting device 10 is disposed on the upstream side in the transport direction when viewed from the gates G1 to G9 (hereinafter collectively referred to as gate G) disposed on the transport path 6, the attitude correction device 10 is always provided. The banknote P can be sent to the gate G in a state where the banknote P is conveyed to the correct posture. For this reason, for example, as shown in FIG.
In comparison with the case where 0 is not provided (gap Ga ′), FIG.
As shown in FIG. 2, two bills P1, which are continuously conveyed,
The gap Ga between P2 can be made constant, and the bill P
Sufficient time required for switching the gate G between 1 and P2 can be secured, and the gate G can be reliably switched between the banknotes P1 and P2.

On the other hand, as shown in FIG. 11, if the skew is generated in the preceding banknote P1 without providing the posture correcting device 10, for example, the transport gap Ga 'between the banknote P2 and the following banknote P2 is increased. It becomes smaller on one side in the width direction, and the bills P1, P2
In the meantime, the time required for switching the gate G cannot be secured,
There has been a case where the switching of the gate G causes a jam without being made in time. For this reason, in the present invention, the attitude correction device 10 is provided upstream of the gate G.

Sixth, since the posture correcting device 10 is disposed on the upstream side in the conveyance direction from the six stacking units 15a to 15f (hereinafter collectively referred to as the stacking unit 15), the conveyance posture of the banknote P is always correct. The paper money P can be sent to the predetermined stacking unit 15 in a state corrected to the posture, and the stacking state of the banknotes P can be stabilized.

FIG. 13 is a perspective view of the stacking unit 15, and FIG. 14 is a front view of the stacking unit 15. The stacking unit 15 has two impellers 81 and 82 provided coaxially side by side on the front side and the rear side of the apparatus. Each of the impellers 81 and 82 includes a plurality of blades 81a and 82a extending from the outer periphery in the direction T in which the banknote P is fed. Further, at the lower right of the impellers 81 and 82 in the drawing, an accumulation chamber 83 for accumulating the banknotes P sent through the impellers 81 and 82 is provided.

The impellers 81 and 82 are indicated by arrows R in FIG.
In the direction of arrow T through the horizontal transport path 14 (not shown).
It is received once during 2a and is accumulated in the corresponding accumulation chamber 83. According to the present invention, for example, as shown in FIG. 16, since the banknote P corrected in a correct posture is sent toward the blades 81a, 82a of the impellers 81, 82, the banknote P is reliably sent to the blades 81a, 82a. The banknotes P are accepted and the state of accumulation of the banknotes P in the accumulation chamber 83 is stabilized.

On the other hand, if the attitude correcting device 10 is not provided on the upstream side of the stacking unit 15, for example, as shown in FIG. 15, the shifted banknote P2 is applied to the blades 81a, 82a of the impellers 81, 82. It is sent toward, and banknote P2
Is not reliably received by the blades 81a and 82a, and in the worst case, a problem occurs in which the banknote P2 falls off. Even when the banknote P2 is received by the blades 81a and 82a, there is a problem that the stacking state of the banknotes P in the stacking chamber 83 becomes unstable. For this reason, in the present invention, the posture correction device 10 is disposed upstream of the accumulation unit 15.

Seventh, since the posture correcting device 10 is disposed upstream of the banding processor 4 in the conveying direction, the banknote P whose conveyance posture has been corrected to the correct posture can always be sent to the banding processor 4. Thus, the state of stacking of the banknotes P in the stacking section 17 can be stabilized, and the banding state of the banding section 18 can be stabilized.

Conversely, unless the posture correcting device 10 is provided upstream of the banding unit 4, the skewed and shifted banknotes P will be sent to the banding unit 4,
7, the stacking state of the banknotes P becomes unstable, and the banknotes P whose stacking state is unstable are sent to the banding unit 18, and the banding state of the banknotes P deteriorates. For this reason,
In the present invention, the posture correction device 1 is located on the upstream side of the
0 was arranged.

As described above, according to the present invention, the transport path 6
Since the posture correction device 10 for correcting the conveyance posture of the banknote P taken out above is provided immediately after the loading unit 5 (that is, each processing mechanism unit 7, 8, 12, 4, 15, G), the conveyance path 6
The transport posture of the banknote P taken out above can be stabilized, and various problems caused by the poor posture of the banknote P can be prevented.

In the present invention, as shown in FIG.
With respect to the transport path 6 defined by the three pairs of transport belts 49a, 49b, 49c, the center of the banknote P is located on the center line 6a of the transport path 6, and the edge along the longitudinal direction of the banknote P is the center. Since the transport posture of the bill P is defined so as to be orthogonal to the line 6a, three pairs of transport belts 49a, 49b49
There is almost no possibility that the banknote P is easily detached from c.

On the other hand, as shown in FIG. 17, when the conveying posture of the bill P is defined based on one end in the width direction of the conveying path 6, for example, the other end of the smallest bill P1 is located on the rear side of the apparatus. Of the conveyor belt 49c, and the possibility of falling off increases. Therefore, in the present invention,
The transport posture of the banknote P is defined such that the center of the banknote P is located on the center line 6a of the transport path 6 and one end along the longitudinal direction of the banknote P is orthogonal to the center line 6a.

The present invention is not limited to the above-described embodiment, but can be variously modified within the scope of the present invention. For example, in the above-described embodiment, the input unit 5
A case has been described in which the attitude correction device 10 is disposed on the transport path 6 between the sensor and the detection unit 7. However, the present invention is not limited to this.
2. It may be disposed on the transporting path 6 immediately before the sealing section 4, the stacking sections 15a to 15f, or the gates G1 to G9. In this case, the number of the posture correction devices 10 may be any number.
