Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet handling apparatus for an automated teller machine used in a financial institution, etc., and particularly to separating paper sheets suitable for carrying paper sheets of different sizes depending on transactions. Regarding the device.

[0002]

2. Description of the Related Art In a conventional paper sheet separating apparatus, for example, as described in Japanese Patent Laid-Open No. 55-13482,
By correcting the separation speed of the paper sheets according to the paper sheet distance information, the correction of the paper sheet intervals on the transport path is realized. However, no consideration has been given to detecting the size of the paper sheet to be separated and separating at the optimum separation speed.

[0003]

In the above prior art, the separation mechanism speed is switched between the high speed and the low speed by the means for detecting the sheet interval between the separated sheets to change the feeding timing of the sheets. However, there are problems shown in the following (1) to (3). (1) Since the speed of the separation mechanism is changed during the separation of the paper sheets, the paper sheets being separated are easily overloaded and damaged. (2) A sheet spacing detection circuit is required, which complicates the configuration. (3) Since the speed control of the separation mechanism is performed in real time according to the sheet interval, the control method becomes complicated. An object of the present invention is to improve such problems, provide a paper sheet separation mechanism that does not require a paper sheet distance detection circuit, does not apply an overload to a paper sheet that is being separated, and has an easy speed control. To do. Another object of the present invention is to provide a paper sheet separating apparatus capable of optimizing the paper sheet state on the conveyance path according to the size of the paper sheet and shortening the conveyance processing time.

[0004]

In order to achieve the above object, the paper sheet separating apparatus of the present invention is a paper money separating mechanism (feed roller) for feeding out the paper money stacked one by one in a storage box for each type. , A gate roller, a push plate, a pickup roller, etc.), a motor for driving the same, and a conveyance path for conveying the bills fed out by the separating mechanism, the size of the bills fed out from the storage box. A means for storing information (dimension storage unit) and an optimal feeding speed are sequentially calculated based on the information, and a speed signal is sent to the motor to make the separation speed constant for each type, thereby making the bills on the conveyance path. It is characterized in that a means (control section) for controlling the state of is provided.

[0005]

In the present invention, the size information of the bill is stored in advance in the size storage unit. Then, when the bills are separated one by one by the separating mechanism and fed out to the conveying path, the control unit detects and outputs the size information of the bills to be separated by the size detecting unit, and the calculating unit detects the optimum size based on the size. The feeding speed is calculated, and the speed changing means controls the separation speed during the separation to be optimum and constant. This makes it possible to optimize the state of the banknotes on the transport path (banknote spacing, load, etc.) according to various dimensions. Further, it is possible to facilitate the speed control and shorten the transportation processing time.

FIG. 4 is a flow chart showing the operation of the bill separating mechanism in the embodiment of the present invention, and FIG. 5 is a diagram showing the bill state on the conveying path in the embodiment of the present invention. In this embodiment, as shown in FIG. 4, first, the AC motor 7 for driving the transport path 8 is turned on (401). Further, when the withdrawal from the cassette 15 is instructed (402), the bill size of the cassette 15 is read from the size storage unit 1 and the optimum speed signal is given to the pulse motor 4 (403). That is, the bills 13 stacked in the cassette 15 have the upper end position kept constant by the push plate 14 shown in FIG. 3, and the optimum rotation speed of the feed roller 10 is calculated from the dimensional information of the bills 13. .. Next, the pickup roller 1

7, 411, a method for calculating the payout speed (the optimum rotation speed of the feed roller 10) based on the information in the dimension storage unit 1 will be described. The transport speed is 1600
It should be kept at mm / s. In this embodiment, when the control unit 2 calculates the separation speed, the separation speed is calculated by the following formula. Feed roller rotation speed (rotation / second) = conveyance path movement dimension per second / (banknote size + banknote interval) As a result, when the banknote (length 150 mm) shown in FIG. When it is driven at 8 revolutions / second, a bill interval of 50 mm is secured. The separation speed in this case is 8 sheets / second. On the other hand, when separating the 50 mm bill shown in (b), the feed roller 10 is rotated 16 times /
When driven in seconds, a banknote of 50 mm is secured. In this case, the separation speed is 16 sheets / second. According to this embodiment, when long bills are separated, the optimum rotation speed of the feed roller is slow, so that the bill interval on the conveyance path is guaranteed.
Further, when short bills are separated, the rotation speed of the feed roller is high, so that the bill interval on the transport path can be guaranteed and the processing capacity can be improved. Further, since bills of the same denomination are stacked in one cassette, the separating speed of the separating mechanism is constant, an overload is not applied to the bills during separation, and speed control is easy.

[0008]

According to the present invention, the following effects (1) to (5) can be obtained. (1) Since the separation mechanism during paper sheet separation can be driven at a constant speed,
There is no overload on the paper sheet being separated. (2) Since the method does not detect the sheet interval, the sheet interval detection circuit is not necessary, which is useful for cost reduction. (3) Since the speed control of the separation mechanism is not performed in real time, the load on the control unit can be reduced. (4) For sheets of various sizes, the state of the sheets on the transport path can be optimized. (5) For paper sheets of various sizes, the state of the paper sheets on the transport path can be optimized, which helps to shorten the transport processing time.
