Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a device for dispensing paper sheets such as banknotes, which is applied to, for example, an automatic teller machine, a money exchange machine, or an automatic ticket vending machine.

<Background of the Invention> Conventionally, money exchange machines or ticket vending machines usually store two types of banknotes, 5,000 yen bills and 1,000 yen bills, and dispense them as money exchange or change. However, in conventional dispensing devices, different types of banknotes are stacked and stored in cassettes of the same type, and each cassette is provided with a dispensing mechanism, a discharging mechanism, and an ejection port, making the device large, complicated, and expensive. ,Moreover,
There were problems such as a lack of operational reliability.

<Objective of the Invention> In order to solve the above-mentioned problems, the present invention makes it possible to downsize and control the device by reciprocating a plurality of parallel cassettes in a parallel direction to correspond to a single feeding mechanism and sequentially feeding the cassettes. 4. It is an object of the present invention to provide a new paper sheet feeding device that can simplify the process and improve reliability of operation. ,.

<Description of Embodiments> FIG. 1 shows the internal structure of a device for dispensing paper sheets such as banknotes in a money changer, an automatic teller machine, and a ticket vending machine.

The above-mentioned paper sheet feeding device is a feature of the present invention, and includes a plurality of cassettes 22a and 22 each containing different paper sheets such as 1,000 yen bills, 5,000 yen bills, and different types of banknotes.
cassette unit 2 in which cassette units b are arranged side by side, a slide mechanism 3 for reciprocating the cassette unit 2 in the parallel direction of the cassettes, and a slide mechanism 3 disposed above the cassette unit 2, which alternately corresponds to each cassette by moving the cassette unit. It consists of a feeding mechanism 4 that feeds out laminated paper sheets one by one from above, and a discharge mechanism 7 disposed between the feeding mechanism 4 and a take-out port 8.

The cassette unit 2 is provided with a support plate 21 that can freely reciprocate on a slide shaft 11.11 installed between the side walls 1 of the box, and a plurality of cassettes 22a are arranged in parallel on the support plate 21.
, 22b are removably loaded.

Each of the cassettes 22a and 22b is a casing that has a volume suitable for accommodating stacked paper sheets and has an open rear half on the top surface, and inside thereof is a mounting plate 23 that is energized to rise. Stacked paper sheets 24 of 1,000 yen, 5,000 yen, etc. are loaded onto this mounting plate 23.

The slide mechanism 3 of the cassette unit has a rack 31 mounted and fixed on the lower surface of the support plate 21 in parallel with the slide shaft 11, and a pinion 33 is provided in the box on the output shaft of a forward and reverse rotation motor 32. When this is engaged with the rack 31 and limits both ends of the reciprocating motion, limit switches 34 and 35 are provided to control the forward and reverse directions of the motor 32. The rotation reciprocates between the switches 34 and 35 along the slide shaft 11, and the opening surface of each cassette 2a or 2b is made to correspond alternately to the feeding mechanism 4 at the end of movement.

The feeding mechanism 4 includes a swinging lever 41 whose base end is pivotally supported on the box side wall 1 above the cassette unit 2, and a feeding roller 42 is pivotally supported at the tip of the lever 41 to feed the belt 4.
3 to a drive motor 44, and the swing lever 41 is linked to a plunger 4'7 of a solenoid 46 via a link 45. It is displaced downward, and when it descends, it presses against the stacked paper sheets in the corresponding cassette 22a and sequentially recycles them from the top side.

On the feeding side of the feeding roller 42, there is a friction roller 5 made of rubber, which is located below the sheet conveyance surface and is urged upward by a spring 51, and above the roller 5, the motor 4 is placed.
4 is provided with a delivery roller 6 connected via a belt '61, and when two sheets are fed out from the delivery roller 42, the friction roller 5 stops the transfer of the lower paper sheet and the paper is sent out. The roller 6 sends out the upper paper sheet to the single-sheet discharge mechanism 7, and the leading edge of the unnecessary paper sheet is detected by the sensors 52 and 52 arranged vertically facing each other, and the solenoid 46 is turned off.
F is activated.

The discharge mechanism 7 has a pair of endless discharge bells 71 and 72 stretched between the friction roller 5 and the discharge roller 6 and the outlet 8, vertically sandwiching the conveyance surface, and one pulley of the belt 71. The same belt 61 as the delivery roller 6 is wound around the delivery roller 6 and driven, and the paper sheets are taken out from the delivery roller 6 through the outlet 8.
The discharge path is equipped with a discharge confirmation sensor 81.
81 is provided, and the motor 44 is stopped by the operation of the sensor.

FIG. 3 shows an example of the circuit configuration of the sheet feeding device.

Arithmetic processing unit 9 in the figure
The singUnit (hereinafter simply referred to as r cPU J) decodes the program stored in the memory 91, performs various calculations and processes while reading and writing data to the memory 91, and also reads the cassette via the 110 interface 92. Forward and reverse rotation motor 3 for movement
2. Limit switch 3 that detects both ends of the cassette movement
4 and 35, a solenoid 46 that raises or lowers the feed roller 42 to press it against the sheets in the cassette, a motor 44 that rotationally drives the feed roller, and a solenoid that detects that the friction roller has stopped unnecessary sheets. The controlling sensor 52 detects that a certain number of paper sheets have been discharged from the outlet 8, and controls each input/output operation of the discharge confirmation sensor 81 that controls the motor.

FIG. 5 shows the control flow of the filter paper sheet feeding device according to the present invention. At the start, each cassette 22a and 22
Paper sheets 24 of different types, such as 1,000 yen bills and 5,000 yen bills, are separately stacked and housed in cassette 22a, and one cassette 22a is connected to the feed roller 4.
It is positioned below No. 2 and is waiting to dispense paper sheets and exchange money. Now, if a 10,000 yen bill is inserted and there is an instruction to exchange it for a 5,000 yen bill, the determination in step 101 as to whether or not to dispense a 1,000 yen bill will be "No", and the process will proceed to the next step 102. In step 102, the determination as to whether or not a 5,000 yen bill is to be dispensed is "YES", and the process proceeds to step 103. In the next step 103, the limit switch 35
is in the on state. In this case, if step 103 is "NO", step 1
12, the motor 32 is reversed to move the cassette 22a below the feeding roller, and as a result, step 103 becomes ``YES'', the process proceeds to step 104, where the motor 44 is turned on, and step 105 is when the solenoid 4 is turned on.
6 is turned on, the feed roller 42 is driven to rotate and descends to feed out the paper sheet 24 in the corresponding cassette 22a, that is, one 5,000 yen bill, and discharges it through the discharge mechanism 7 to the outlet 8. Proceed to the next step 106. Step 106 is
It is checked whether or not the sensor that detects that two sheets of paper are fed out from the feeding roller 42 in a stacked state is in the ON state. In this case, step 106 is TT NOI+.
Therefore, proceed to the next step 107 and step 10
Step 7 checks whether the release confirmation sensor is in the on state. Since the answer in step 107 is ``YES'', the process proceeds to step 108, where the solenoid 46 is turned off, and in the next step 109, the motor 44 is turned off, and the operation of dispensing the 5,000 yen bill is completed.

If there is an instruction to exchange the next 10,000 yen bill, the determination in step 1101 is ``YES'' and the process proceeds to the next step 110. In step 110, it is determined whether the limit switch 34 is in the on state. If the determination is 11No +1, proceed to the next step 111,
The motor 32 rotates to move the cassette support plate 21 laterally,
The previous cassette 22a is retracted from the feed roller 42, and the cassette 22b containing thousand yen bills is positioned. As a result, the determination in step 110 becomes "YES", so the process proceeds to step 104, where the feed roller 42 is rotated and lowered to release the corresponding cassette 22 in the same way as described above.
The paper sheets 24 in a, that is, the 1,000 yen bills, are fed out one by one. If the determination in step 106 is "YES" as to whether the sensor for detecting two-sheet feeding is on, the process proceeds to step 108, in which the solenoid is actuated to raise the feeding roller, and the rotation of the motor 44 is stopped. Prevents unnecessary paper sheets from being fed out.

<Effects of the Invention> As described above, the present invention enables a plurality of cassettes containing different types of paper sheets to be reciprocated in the parallel direction of the cassettes, and allows each cassette to be fed out in correspondence with a single feeding mechanism. Therefore, compared to the conventional device in which each cassette has a feeding mechanism, a discharging mechanism, and an ejection port, the device can be simplified and smaller, and its operating performance can be improved, thereby achieving the purpose of the invention. .
