Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automated teller machine, which is used by financial institutions and the like.
The present invention relates to a paper sheet handling apparatus such as ATM, etc., and more particularly, to a paper sheet transporting apparatus which is effective when a paper sheet on a transport path has a fold in a transaction or the like.

[0002]

2. Description of the Related Art A conventional apparatus has been used for reversing the conveying direction of paper sheets, as described in JP-A-62-171863.

[0003]

The above-mentioned prior art does not take into account the breakage of the edges of the paper sheets. Therefore, even if the paper sheets with the broken edges are conveyed, the correction of the breakage of the ears is not performed. However, there is a problem in that the sheet is conveyed in the above-mentioned manner, which deteriorates the smooth conveyance of paper sheets. It is an object of the present invention to efficiently correct the edge breakage of paper sheets.

[0004]

In order to achieve the above-mentioned object, an edge breakage correction means is provided in the space of the storage means so that the edge breakage of the paper sheet can be corrected when the paper sheet passes. Further, a short side dimension measuring unit for the sheet and a unit for controlling the space length according to the dimension are provided so that the edge bending correction can be optimized.

[0005]

According to the present invention, in addition to the edge-folding correction means, the lateral dimension of the sheet is measured as a means for preventing the sheet from accumulating in the storing means by shortening the space length when the sheet dimension is short. However, since the means for controlling the space length according to the dimension is provided, it is possible to efficiently correct the edge breakage of the paper sheet.

0 is a mechanism for picking up and carrying banknotes from both sides, and the second carrying path consisting of the carrying belts 46, 47 is a mechanism for picking up and carrying banknotes from both sides by the pair of upper and lower carrying belts 46, 47. ing.

Next, the detailed operation of the paper sheet handling apparatus of claim 1 will be described. In the first conveyance path formed of the conveyance belts 18 and 20, the pulleys 29 and 30 and the sheet roller 36 rotate counterclockwise, and the pulleys 33 and 34 rotate clockwise to hold and convey a bill. The second conveyor path consisting of the conveyor belts 46, 47 has the pulleys 42, 43 counterclockwise, the pulleys 44,
45 rotates clockwise, and holds and conveys a bill. The banknotes sent from the first transfer path are transferred into the storage means 37 while the sheet rollers 36 rotating counterclockwise press the front ends of the banknotes against the traveling surface of the transfer belt 20.
The bills conveyed into the storing means 37 have a sheet roller 36 at the rear end.
The length of the storage means is determined so that it will stop at the position where it is hit by the paper.The rear end of this banknote is pressed against the sheet roller 36 rotating in the counterclockwise direction so that it is pressed against the traveling surface of the conveyor belt 46 and the conveyor belt. It is pinched in the 2nd conveyance path which consists of 46 and 47, and this time the rear end is the top and is conveyed. At that time, the ear fold correction tabs 38, 39 inside the storing means 37
By this, the fold of the bill is corrected.

FIG. 3 shows a schematic view of the edge-folding correction section of the paper sheet handling apparatus of (claim 2).

In addition to FIG. 2, FIG. 3 is a sensor for detecting the length of a bill to be conveyed on the first conveying path formed of the conveying belts 18 and 20.

FIG. 4 is a mechanism diagram of the storage means 37 and the stoppers 40 and 41 of FIG. 3, and FIG. 5 is a view when switching the stoppers according to the short dimension of the paper sheet of the paper sheet handling apparatus of (claim 2). The operation | movement flowchart is shown.

Next, the detailed operation of the paper sheet handling apparatus of claim 2 will be described with reference to the operation flowchart of FIG. The banknotes sent from the first transport path including the transport belts 18 and 20 have a sheet roller 36 that rotates counterclockwise.
The bills are conveyed into the storage means 37 while being pressed against the traveling surface of the conveyance belt 20. Here, in the case of the paper handling apparatus according to (claim 1), since the length of the storing means is determined in advance, the storing means may be used when banknotes of different sizes have been deposited or when the degree of ear folding is large. 37
It was thought that banknotes would remain inside. Therefore,
An encoder for outputting the number of pulses that is proportional to the drive length of the transport path is provided in the transport path drive motor, and the banknote monitoring sensor 35 on the transport path is dark while integrating the number of pulses.
The driving distance is calculated from the number of pulses in the meantime to obtain the bill size, and the stopper corresponding to the short size is turned ON / OFF. This makes it possible to stop the rear end of the bill conveyed in the storage means 37 at the position where it is hit by the sheet roller 36, regardless of the short dimension of the bill. The trailing edge of this bill is the sheet roller 36
It is pressed against the traveling surface of the conveyor belt 46 by being struck by and is sandwiched by the second conveyor path composed of the conveyor belts 46 and 47, and this time the rear end is conveyed first.
At this time, the fold correction tabs 38 and 39 inside the storage means 37 correct the fold of the bill.

Taking Japanese banknotes as an example, the short dimension is 76 mm, so if the short dimension is larger than 70 mm, the stopper
Both 40 and 41 do not turn on. If it is larger than 64 mm and 70 mm or less, turn on only the stopper 41 (solenoid 48: OFF, solenoid 49: ON), and if it is 64 mm or less, turn on only stopper 40.
(Solenoid 48: ON, Solenoid 49: OFF). Here, it is assumed that an edge-folded bill as shown in FIG. 6 has been conveyed. While the bill is being conveyed to the position of the sensor 35 on the first conveying path and the bill is being detected by the sensor 35 (during the sensor dark), the number of phase advance pulses of the conveying motor is integrated.
When a bill passes through the sensor 35 (when sensor dark → light), the bill size is calculated from the integrated value during passing and it is determined to be 68 mm, and only the solenoid 49 is turned on and the stopper 41
Take off. Then, the bills are switched back in the storage means 37, guided to the second transport path and transported. The solenoid 49 is turned off at the timing when the bill tip is detected (sensor dark) by the sensor 50 on the second transport path, and the stopper is turned on.
Stores 41. By making the judgment value fine or changing the judgment value, more optimized control becomes possible and it is possible to cope with paper sheets other than Japanese banknotes.

By providing two paper sheet handling devices of the present invention in combination, the leading edge of the bill is corrected at the front edge of the bill and the second edge is corrected at the opposite end of the bill. The ear breakage will be corrected.

[0018]

As described above, according to the present invention, it is possible to efficiently correct the folds of the sheet taken into the sheet conveying device regardless of the degree and the sheet size, and convey the sheet, which is suitable for ATM and the like. A paper sheet conveying device can be provided. ATM
For example, by correcting the edge folds, not only the frequency of occurrence of banknote jams in the conveying path after the correcting unit 3 is significantly reduced, but also the banknotes are corrected by the identifying unit 4 in the state in which the ear folds are corrected. Is conveyed, so skew due to broken ears,
The number of error factors before bill discrimination such as abnormal thickness and shortness is reduced, and the number of bills judged to be unfit is reduced. Furthermore, the stacking state in the recycle boxes RB11 to 13 becomes more orderly,
