などが難しくなる。In such a bill processing apparatus, it is desired that the bills that have been separated and conveyed are not inclined and are conveyed at normal intervals. Because the bills are skewed (skew),
If the paper is conveyed with a narrow space (short pitch), pattern matching processing such as printing of banknotes performed by the inspection unit becomes difficult.

There was a problem that could not be done. As a result, banknote skew, clogging of conveyance intervals, etc. occur,
Often caused disability. Therefore, the transport device 22 according to the present invention solves these problems by using the means described below.

Is shown in detail. In the figure, endless drive belts 2a and 2b as belt-shaped conveying means are juxtaposed at a predetermined interval and are stretched between rotatable rollers 8a and 8b and 11a and 11b, respectively. Endless driven belts 1a and 1b as the other belt-shaped conveying 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, both ends of the banknote P are sandwiched between the drive belts 2a and 2b and the driven belts 1a and 1b and are conveyed in the direction of the arrow shown in the figure. The rotatable rollers 9a, 9b are for supporting the midway portions of the belts 2a, 2b, 1a, 1b.

Similarly, the drive roller 6b is also driven by the pulse motor 7b and a control unit which will be described later. Since the pulse motor 7b is also used for other conveyance in this embodiment, its speed and rotation direction are unchanged. Is.

Since the driven belts 1a and 1b are pulled by a and 6b to move, the driven belts 1a and 1b are opposed to each other by the driving belts 2a and 2b.
It operates following b.

If there is a difference in speed between (b, 2b), the sandwiched banknote P has a small rigidity, so it seems that the banknote P is bent.
As a result of the experiment, if the rigidity is about the same as a banknote, no bending occurs, and due to the slight slip of the left and right conveyor belts in the direction orthogonal to the conveying direction, only the inclination changes while maintaining the rectangular state, and normal conveyance is possible. It is possible to do.

および搬送間隔が計測されるようになっている。Phototransistors 3a and 4a, which are non-contact type sensors 3 and 4 as detecting means for detecting passage of the banknote P, are provided at a predetermined position of the transporting device 22 thus constructed, for example, in the vicinity of the starting end. Infrared light emitting diodes 3b and 4b, which are light sources, are arranged in a direction orthogonal to the conveyance direction of the banknote P, separated by a predetermined distance. These sensors 3, 4
As will be described later, the inclination and the conveyance interval of the banknote P are measured based on the output signals of the above.

The output signals of the sensors 3 and 4 are sent to the control unit 41, respectively. Based on the output signals of the sensors 3 and 4, the control unit 41 respectively measures the inclination of the banknote P and the conveyance interval at the respective positions of the sensors 3 and 4, and measures the measurement, as will be described later in detail. Based on the result, the drive circuits 42 and 43
The pulse motors 7a and 7b are controlled to be driven via the.

The operation of No. 2 will be described. Now, it is assumed that the banknote P transported from the upstream transport unit (for example, the feeding mechanism 21) is skewed at an angle as shown in FIG. The banknotes P are belts 2a, 2b, 1 which are driven at a constant speed at the same speed as the preceding stage transport section.
When it is nipped and conveyed by a and 1b and reaches the position of FIG. 6, the bill P blocks the sensor 4. Further, when it is conveyed at a constant speed, the position of FIG. 7 is reached and the sensor 3 is also blocked.

したがって、図6および図7のスキューは正の量とな
る。The control unit 41, which has received the output signals of the sensors 3 and 4, measures the time required to reach the states shown in FIGS.
The skew amount and the skew direction of the bill P are calculated from the distance between the optical axes. Here, when the direction of the skew is represented by a symbol, for example, the CCW direction (counterclockwise direction) is a positive skew and the CW direction (clockwise direction) is a negative skew.
Therefore, the skew in FIGS. 6 and 7 is a positive amount.
【0026】次に、ある時間内に等速運動する搬送方向
に対して右側の駆動ローラ6bに対し、搬送方向に対し

が必要であり、単位時間以内に左側の駆動ローラ6aを
「80×tan(10°)=14.1mm」多く動かす
必要が生じる。Next, it is determined how much the left drive roller 6a with respect to the transport direction should be moved with respect to the right drive roller 6b with respect to the transport direction which moves at a constant speed within a certain time. For example, if the skew angle is 10 ° and the optical axis interval between the sensors 3 and 4 is 80 mm, correction in the CW direction is necessary, and the drive roller 6a on the left side is set to “80 × tan (10 °) = 14 within a unit time. .1 mm ”needs to be moved a lot.
【0027】これらの計算を制御部41によって行な

a、)が64mm進むように、左側の駆動ローラ6aの
速度を制御することにより、紙幣Pは傾きが修正され、
傾きのない状態で搬送されることとなる。These calculations are performed by the control unit 41, and as a result, the rotation speed of the variable side pulse motor 7a is changed. For example, the right conveyor belt (1b, 2
While the b) advances by 50 mm, the left conveyor belts (1a, 2)
By controlling the speed of the drive roller 6a on the left side so that (a,) advances by 64 mm, the inclination of the bill P is corrected,
It will be conveyed without any inclination.
【0028】こうして、制御終了後、左右の搬送ベルト
(1a,2a、1b,2b)の速度を通常の搬送速度に
戻して駆動することにより、左右ともに通常の搬送速度
となり、後段の搬送路23に紙幣Pを引き渡すことが可
能となる。After the control is completed, the speeds of the left and right conveyor belts (1a, 2a, 1b, 2b) are returned to the normal conveyor speed to drive the conveyor belts. It becomes possible to deliver the banknote P to.
【0029】実際に紙幣処理装置では、たとえば、紙幣

一定値以内におさえることが可能となる。In actuality, in the bill processing apparatus, for example, the length of the bill P is 76 mm, but the interval between the bills P to be conveyed is usually about 80 mm.
In No. 2, since the skew is controlled during the conveyance length of about 50 mm, the processing time can be sufficiently made. By performing the above control continuously for all the banknotes P passing through the transport device 22, the skew can be suppressed within a certain fixed value.
【0030】次に、左側の駆動ローラ6aについて、時
刻に対してモータ速度をどのように変えるかを詳細に説
明する。この場合、以下の3つの理由から図8に示すよ
うに、修正の開始から開始と終了との中点までをランプ
アップし、終了までをランプダウンするのが適当であ
る。 (1)加速度が大きいとモータに大きな負荷がかかるた
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
度)となっていなければならない。 (3)加速度の絶対値が一定であるほうが制御が簡単で
ある。たとえば、スキュー修正に要する時間を31.2
5ms、定常速度を1600mmとすると、中点におけ
る最高速度は、 29.12×2÷31.25×1000+1600=3
464mm/s となる。したがって、図8のように左側の速度を時刻に
対して変えれば目標値が得られる。Next, how the motor speed of the left drive roller 6a is changed with respect to time will be described in detail. In this case, it is appropriate to ramp up from the start of correction to the midpoint between the start and end and ramp down to the end, as shown in FIG. 8, for the following three reasons. (1) If the acceleration is large, a large load is applied to the motor, so it is necessary to make the acceleration as small as possible. (2) The speed must be a steady speed (speed on the right side) before and after the skew correction. (3) The control is easier if the absolute value of the acceleration is constant. For example, the time required for skew correction is 31.2
If the steady speed is 5 ms and the steady speed is 1600 mm, the maximum speed at the midpoint is 29.12 × 2 ÷ 31.25 × 1000 + 1600 = 3.
It becomes 464 mm / s. Therefore, the target value can be obtained by changing the speed on the left side with respect to time as shown in FIG.

に漸近することがあり、厳密な制御が困難となるので、
速度の時間変化は数種のバリエイションをとる。On the contrary, as shown in FIG. 9, when it is desired to correct in the CCW direction, if the same procedure as in the CW direction is performed, the speed gradually approaches zero depending on the magnitude of the skew as shown in FIG. Since it is difficult to control strictly,
There are several variations in the speed change over time.

The shaded areas in the figure represent the lagging distance on the left side with respect to the right side, and the acceleration is minimized according to the magnitude of the lagging distance obtained from the skew and the calculated value.
The three stages (b) and (c) are used properly. In the diagram (a), the speed is reduced to a certain speed at the start of correction, and then ramped up to a steady speed. In the diagram (b), the speed is set to zero at the start of correction, and after a certain period of time, the speed is ramped up to the steady speed.
In the diagram (c), the velocity is set to zero at the start of the correction, then ramped up in the opposite direction, the velocity is set to zero again at a certain time, and thereafter, the same control as in the diagram (b) is performed. Note that these control methods may be selectively used according to the magnitude of skew.

す。In both cases of correction in the CW direction and the CCW direction, if the skew is abnormally large and an excessive load is applied to the motor (when the motor cannot accelerate to that speed), the maximum range is possible. It is possible to select whether to carry out the correction or to carry the paper at a normal carrying speed without making any correction. The flow of the above control is shown in the flowchart of FIG.

に加わる負荷が小さくなるというメリットがある。In the above description, the pulse motor 7b on one side (right side) is explained as fixed speed, but it is also possible to set variable speed on both sides (right side, left side). For example, C
When it is desired to correct in the W 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 that when the speed is fixed on one side, the load applied to the pulse motor is reduced.

制御が可能となる。Further, in the above description, an example in which the present apparatus is used to correct the skew has been described, but a mechanism for continuously transporting the banknotes P one by one is used to correct the banknote interval as follows. It can also be a mechanism. For example, the driving roller 6a and the driven roller 6b are integrated so that they can be driven by one pulse motor. Alternatively, the drive roller 6a and the driven roller 6b are synchronously driven.
The speed of the pulse motor is increased when it is desired to shorten the transportation interval of the currently transported banknote P with respect to the already sent banknotes P, and the speed of the pulse motor is slower than usual when the transportation interval is desired to be increased. By doing so, the conveyance interval can be controlled.

For example, the skew of the banknote P transported from the previous stage is +5 degrees, and the distance from the banknote P transported previously is 30 m.
If it is m, the skew is corrected first, and after the skew correction is completed, the speed of the left and right rollers is made slower than usual in order to widen the conveyance interval, and the control may be performed in the direction of increasing the conveyance interval. . It is also possible to correct the skew and the conveyance interval at the same time.
