DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet processing apparatus.
In particular, the present invention relates to a paper sheet processing apparatus that conveys banknotes.

[0002]

2. Description of the Related Art In a conventional paper sheet processing apparatus for processing banknotes, a width direction of a cash slot and a banknote cassette is a dimension obtained by adding a margin of several millimeters to several tens of millimeters to a maximum width of a banknote that can be handled. The width of the conveyance path from the cash slot to the bill cassette is set to have a margin of 20 to 30 mm more than the width of the cash slot.

[0005] Then, due to banknote misalignment such as skew, deposit, or the like, or a method of pulling bills into the bill cassette of the apparatus, etc., the bill is shifted from the deposit / withdrawal port and the end position of the bill cassette in the width direction. In the case of occurrence, a guide is provided for invoking bills from the width of the transport path to the width of the cash slot and the bill cassette, and the bills come into contact with the guides during free flight of bills when stacking bills in the bill slot or bill cassette. The bills were aligned to the width of the deposit and withdrawal port and the bill cassette by being called.

[0004]

In the conventional paper sheet processing apparatus, when a bill is deviated from the position of the width direction end of the bill cassette and the width direction of the bill cassette when handling the bill, the bill is brought into contact with a guide to make the bill slot. In addition, since the bills are drawn up to the width of the bill cassette, there is a problem in that if the bills are contacted excessively, the bills are disturbed and a trouble is caused. In addition, since the width direction of the deposit and withdrawal port and the bill cassette is determined based on the maximum width of the bills that can be handled, in the case of a small bill having a small width direction size, the irregular amount at the time of stacking is large, and after the bill is taken out. There was also an operational problem that it had to be realigned. Furthermore, in the recirculation type banknote handling machine, in order to dispense the banknotes accumulated in the banknote cassette, the above-mentioned low-value banknotes have a large irregular amount, so that the pressing force of the banknote holding plate during banknote feeding is uneven. There has been a problem that skew is likely to occur when the banknotes tend to be easily formed and when only one side of the banknote is often regulated.

[0005]

According to the present invention, there is provided a paper sheet processing apparatus which inserts a bill between a plurality of pairs of flat belts or rubber rollers and conveys the paper sheets by the rotational frictional force of the flat belt or rubber roller. In a sheet processing apparatus having a kind conveying path, an independent conveying path having a length of at least one sheet in a short side direction of a sheet movable in a direction perpendicular to the sheet conveying direction and a direction of the independent conveying path. The front stage is provided with a sensor for detecting the widthwise conveyance position of paper sheets.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a plan view showing the structure of a transport system according to one embodiment of the present invention. It supports a flat belt 2, a crown roller (a roller whose diameter becomes larger as it approaches the center than the diameters of both ends) 3 and a crown roller 3 that sandwiches usages such as bills and conveys the bills 1 by rotational frictional force. An independent transport unit 7 having a plurality of rotating shafts 4 and having a length of one or more in the direction of the banknote edge incorporated in a frame 6 that is not the same as the transport system 5 in the preceding stage is provided. Further, the independent transport section 7 is supported by a guide shaft 9 supported by a frame 8 of the previous transport system 5 via a linear motion bearing 10 which is movable in the axial direction. Motor 1
2 is movable in the width direction by the rotation of 2.

Further, the independent drive section 7 includes a transport drive motor 1.
3 are provided, and the transport drive belt 14 and the pulley 1
5, the bill 1 is transported at a transport speed equal to that of the transport system 5 in the preceding stage. On the other hand, the transport system 5 in the front stage is provided with a width direction transport position detecting sensor 16 for a banknote constituted by, for example, a diode array and a phototransistor.

The banknote 1 conveyed through the conveyance system 5 in the preceding stage
In the, the transport position in the width direction is detected by the transport direction detection sensor 16 for the banknote in the width direction. When the transport position is offset from the width A of the banknote pay-in / pay-out port and the banknote cassette (not shown above the drawing) as shown in FIG. 1, the transport position is B or more than the offset amount B by the independent transport unit 7. Is corrected. The operation of the independent transport unit 7 when performing the correction includes detecting the leading end or the trailing end of the banknote 1 with the bill width direction transport position detection sensor 16 and then completely capturing the trailing end of the banknote 1 into the independent transport unit 7. After a predetermined time elapses, the drive of the drive motor 12 is started, and the drive is stopped for a time corresponding to the deviation amount.

The independent transport section 7 includes a linear motion bearing 10
The drive motor 1 is movable in the width direction through the
By the driving of the drive belt 2 and the drive belt 11, the banknote 1 is moved in the width direction by a shift amount B or a predetermined amount of B or more while the bill 1 is sandwiched. On the other hand, although the bill 1 is sandwiched between the flat belts 2, the rotation of the transport motor 12 is transmitted by the transport drive belt 14 and the drive pulley 15. Further, the flat belt 2 is rotated via the rotating shaft 4 and the crown roller 3.
Is driven by the frictional force of the flat belt 2 so that the above-described independent transport unit 7 has a transport speed similar to that of the transport system 5 in the preceding stage.
The banknote 1 continues to be fed during the transfer position correction operation, and further, the banknote 1 is transferred and sent to a subsequent transfer system (not shown).

As the operation start timing of the independent transport unit 7, the operation is started after a lapse of a predetermined time until the rear end of the bill 1 is completely taken into the independent transport unit 7, but the bill is moved to the leading end of the independent transport unit. The presence / absence detection sensor may be provided to adopt a method of detecting that the trailing end of the bill has been taken in. Also, the operation of the independent transport unit 7 is stopped after driving for a time commensurate with the offset amount, Needless to say, a system may be adopted in which a bill width direction position detection sensor is provided in the independent transport section 7 to detect the bill width direction position and stop.

Further, it is needless to say that the transfer force may be obtained from the transfer system 5 at the preceding stage without providing the transfer motor 12. In addition, by providing the identification unit 17 at the subsequent stage of the independent transport unit 7, it is possible to identify the denomination by the pattern of the banknote (or paper sheet), etc., and it is possible to separate the respective types and shift the discharge position. Becomes When it is not possible to discriminate the bills (or paper sheets) by the pattern or the like, it is considered that a double-sheet feed or a large skew is present, and the widthwise driving of the independent transport unit 7 is stopped. To prevent malfunction.

[0013]

As described above, according to the present invention, by providing an independent transport section movable in a direction perpendicular to the bill transport direction, the transport position of the bill in the width direction is corrected during the transport and brought into contact with the guide. Since the width of the cash slot and the banknote cassette can be made uniform without any trouble, there is an effect that a conveyance failure can be prevented.

[0014] Further, by providing the above-mentioned independent transport section at the subsequent stage of the discrimination unit, bills can be aligned for each denomination, so that a bill cassette having the same width for each of high-value and low-value banknotes can be provided. In addition to the advantage that the amount of alignment can be regulated and operation time is not required, there is an effect of preventing skew during payment.

Further, when the bill is in an abnormal state such as double-sheet feeding and large skew when the bill status is checked by the identification unit, the independent transport unit is not driven in the width direction to execute the independent transport unit. Has the effect of enabling stable operation of In addition, by providing a plurality of the independent transport units described above, there is an effect that high-speed bill processing becomes possible.
