In such a case, it is difficult to perform a pattern matching process such as printing of banknotes performed by the inspection unit. Further, when the sheet is greatly inclined, there is a limit in the transfer width of the transfer device, which causes a problem that the transfer cannot be performed.

FIGS. 1 and 2 show a transfer device 22 according to the present invention.
Is shown in detail. In the figure, endless drive belts 2a and 2b as belt-like transport means are arranged side by side at predetermined intervals, and are stretched between rotatable rollers 8a and 8b and 11a and 11b, respectively. Endless driven belts 1a, 1b as other belt-shaped transport means
Are arranged side by side in contact with the drive belts 2a and 2b, respectively, and are stretched between rotatable rollers 10a and 10b and drive rollers 6a and 6b, respectively. As a result, the bill P is sandwiched between the drive belts 2a and 2b and the driven belts 1a and 1b, and is conveyed in the direction indicated by the arrow. The rotatable rollers 9a and 9b are for supporting the intermediate portions of the belts 2a, 2b, 1a and 1b.

The driving roller 6b is also driven by a pulse motor 7b and a control unit to be described later. Since the pulse motor 7b is used for other conveyance in this embodiment, the speed and the rotation direction are unchanged. It is.

Accordingly, since the drive belts 2a and 2b are driven independently, the inclination of the bills P sandwiched between the belts 1a and 2a and between the belts 1b and 2b is changed (corrected) due to the difference in drive speed. It is possible to do.

If there is a speed difference between b and 2b), the sandwiched banknote P seems to be bent because of its low rigidity.
As a result of the experiment, if the rigidity is about the same as that of a banknote, no deflection occurs, and only the inclination changes while maintaining the rectangular state due to a subtle slip in the direction perpendicular to the transport direction of the left and right transport belts. It is possible to do.

FIG. 4 schematically shows an electric circuit of the transfer device 22 configured as described above. That is,
The output signals of the sensors 3 and 4 are sent to the control unit 41, respectively. The control unit 41 measures the inclination of the banknote P at the position of each of the sensors 3 and 4 based on the output signals of the sensors 3 and 4, as will be described in detail later. Calculation of the amount to be controlled for correcting the inclination of the banknote P, which will be described in detail, and determination as to whether or not the calculated amount to be controlled is within a predetermined controllable amount is performed.

Next, the operation of the transfer device 22 in such a configuration will be described with reference to the flowchart shown in FIG. First, CW direction (clockwise) and CC
The number of times the skew can be corrected in both the W direction (counterclockwise) (hereinafter referred to as a controllable amount) depends on, for example, the performance that the pulse motors 7a and 7b can output, the dimensions of the apparatus, and the conveyance. It is determined from the speed and the like, and is set and stored in a storage unit (not shown) in the control unit 41.

Next, it is assumed that the banknote P conveyed from the preceding conveyance unit (for example, the feeding mechanism 21) is skewed at an angle as shown in FIG. The banknotes P are driven at a constant speed at a speed similar to that of the preceding-stage transport unit. The belts 2a, 2b, 1a, 1

The control unit 41 which has received the output signals of the sensors 3 and 4 measures the time from the state shown in FIG. 6 to the state shown in FIG.
The skew amount and the direction of the skew of the banknote P are calculated from the distance between the optical axes, and the skew measurement value is determined. At this time, the direction of the skew is represented by a sign. For example, the CCW direction (counterclockwise) is a positive skew, and the CW direction (clockwise) is a negative skew. Therefore, the skew in FIGS. 6 and 7 is a positive amount.

Next, from the skew target value having the same sign with respect to the direction, the control unit 41 controls the drive roller 6b on the right side in the transport direction moving at a constant speed within a certain time, and the left side in the transport direction. It should be determined how much the drive roller 6a should be moved (the amount to be controlled). For example,
If the skew measurement value is 10 °, the target value is −10 °, and the optical axis interval between the sensors 3 and 4 is 80 mm, the CW direction needs to be corrected, and 80 × tan {10 ° − (− 10 °)} = 2.
9.12 mm. This is compared with the controllable amount set and stored in advance, and if it exceeds the controllable amount, the amount to be controlled is replaced with the controllable amount.

かるため、加速度をできるだけ小さくする必要がある。 (2)スキュー修正の前後で速度は定常速度(右側の速

高速度は、 29.12×2÷31.25×1000+1600=3

対して変えれば目標値が得られる。
Next, how the motor speed of the left driving roller 6a is changed with time will be described in detail. In this case, for the following three reasons, as shown in FIG. 8, it is appropriate to ramp up from the start of correction to the midpoint between the start and end, and ramp down until the end. (1) If the acceleration is large, a large load is applied to the pulse motor, so it is necessary to reduce the acceleration as much as possible. (2) Before and after the skew correction, the speed must be a steady speed (right speed). (3) The control is easier when the absolute value of the acceleration is constant. For example, the time required for skew correction is 31.25 m.
s, assuming a steady speed of 1600 mm, the maximum speed at the midpoint is 29.12 × 2 ÷ 31.25 × 1000 + 1600 = 3
464 mm / s. Therefore, a target value can be obtained by changing the speed on the left side with respect to the time as shown in FIG.

Conversely, as shown in FIG. 9, when correction in the CCW direction is desired, if the correction is performed in the same manner as in the CW direction, the speed may gradually approach zero on the way as shown in FIG. Changes in speed over time take several variants, as control becomes difficult. For some ramp down,
Since the pulse motor follows, the speed is changed at the same time at the start of correction in any case.

(A), (b), and (c) are selectively used. (A) In the figure, after decelerating to a certain speed at the start of correction, it ramps up to a steady speed. (B) In the figure, the speed is set to zero at the start of correction, and after a certain period of time, ramps up to a steady speed. In FIG. 3C, the speed is set to zero at the start of correction, then ramped up in the opposite direction, the speed is set to zero again at a certain time, and thereafter the same control as in FIG.

Judging from the skew measurement value in any of the corrections in the CW direction and the CCW direction, if an excessive load is applied to the pulse motor during the correction (excessive acceleration), it is within a possible range. Make maximum modifications.

In the above description, the pulse motor 7b on one side (right side) has been described as being fixed in speed, but both sides (right side, left side) may be variable in speed. For example, when it is desired to correct in the CW direction, the above-described control is performed on the left side, and the control for correcting in the CCW direction is performed on the right side. In this case, since the acceleration of the pulse motor is smaller than in the case where the speed on one side is fixed, there is an advantage that the load applied to the pulse motor is reduced.
