Abstract

PURPOSE:To prevent inserted paper sheets from jamming, by interruptedly turning an electromagnetic clutch on and off, while a driving source is turned on, to be held before an appropriate pressing pressure is obtained in the last storage case, in case of the storage case which first obtains the appropriate accumulation pressing force during preparation of accumulation of the paper sheets. CONSTITUTION:When a pressing plate of a storage case (b) of the storage cases (a), (b) first obtains a proper accumulation pressure during a preliminary process of accumulation, a device, which detects a motor for whether or not it is in reversing in every fixed time after a flag fb becomes 1, turns off an electromagnetic clutch 20b of the storage case (b) for a fixed time only when a detecting switch 25b of the storage case (b) is turned off if the motor is in reversing. And when the switch 25b of the storage case (b) is turned on in the fixed time while a clutch 20b is turned off, the clutch 20b is turned on to be surely held being turned on for a fixed time. In this way, if the clutch 20b of the storage case (b) is turned on and off in a condition of the switch 25b, the pressing plate of the storage case (b), which first obtains a proper accumulation pressure, can be controlled to the proper accumulation pressure even if the switches 25a, 25b are turned off in the different timing, and paper can be prevented from jamming.

Description

Detailed Description of the Invention (a) Field of the Invention The present invention relates to a paper sheet accumulating device built into an automatic teller machine such as an automatic cash dispensing machine used in banking operations, and more specifically, , a plurality of paper sheet storage boxes are provided, paper sheets are sandwiched and accumulated between a pressing plate and a roller in each storage box, and the paper sheet accumulation pressing force due to this push L (-temporary) is detected. This invention relates to a paper sheet stacking device that is detected by a switch.

(B) Background of the Invention In the above-mentioned paper sheet stacking device, as a preparatory process before starting stacking in a plurality of storage boxes, the stacking pressing force of the paper sheets by the pressing plate is adjusted to an appropriate value. Conventionally, the electromagnetic clutch that connects the drive source and the means for retracting the pressing plate is kept on until all the switches for detecting the constant integrated pressing force installed in each storage box are in the Δoff state. The above drive source was turned on.

However, in such conventional devices, the timing at which the detection switch is turned off differs depending on the volume of paper sheets in each storage box, so the detection switch is not set for the storage box in which the detection switch was turned off last. In the case of the storage box, even though the appropriate accumulated pressing force has already been reached, the pressing plate backward movement force from the drive source is still acting until the detection switch of the last storage box is turned off. So,
There is a problem in that an appropriate stacking pressing force is not maintained, and if paper sheets are fed into these storage boxes in this state, paper jams will occur.

(c) Purpose of the Invention This invention provides a method for storing paper sheets even when the storage boxes have a plurality of storage boxes and the volumes of paper sheets stored in each storage box are different.
To provide a paper sheet stacking device capable of preventing paper sheets to be inserted from jamming by obtaining an appropriate stacking pressing force in each storage box in preparation for starting stacking.

(D) Summary of the Invention This invention connects the retraction movement means of the pressing plate in each storage box to a single drive source via each electromagnetic clutch, and also Among the storage boxes, for the storage box that reached the appropriate accumulation pressing force first, a means is provided to continuously turn on and off the electromagnetic clutch of this storage box while the drive source is turned on. It is characterized by being a banknote stacking device.

(E) Effects of the Invention According to this invention, during the preparatory process for stacking paper sheets, while the drive source is on, the electromagnetic clutch of the storage box that has reached the appropriate stacking pressure first is activated. The pressure plate was turned on and off intermittently to make it vibrate slightly, and the obtained appropriate accumulated pressing force was maintained until the appropriate accumulated pressing force was obtained in the last storage box. Even if the detection switch turns off at different times due to differences in the volumes of paper sheets stored in the storage boxes, the slight pressing force necessary for stacking can be obtained for each storage box, and this This eliminates paper jams when feeding paper sheets.

(f) Examples of the invention Embodiments of this invention will be described below in detail based on the N side and the M side.

FIG. 1 is a front view showing a schematic structure of a bill stacking device which is an embodiment of the paper sheet stacking device of the present invention.

Reference numeral 100 designates a storage box, inside of which a belt 2 stretched across a pair of pulleys 12 and 13 is disposed at the lower side, and a pressing plate 1 is fixed to this belt 2 via a mounting bracket 1a.
One end of a coil spring 3 is attached to the downwardly projecting portion 1b of the pressing plate 1, the other end of which is engaged with a body-side attachment portion (not shown).

Reference numeral 10 denotes a conveying roller corresponding to a row in the present invention, and stacks banknotes 11 between it and the pressing plate 1.

The pulley 12 is attached to a shaft 15 that is rotatably supported by the main body of the banknote stacking device, and the shaft 15 is connected to a motor via a gear, an electromagnetic crank, etc., which will be described later. Then, the rotation of the motor causes the pulley 12 to move as shown by arrow C in the figure.
'When rotating in the right direction, the pressing plate 1 moves backward, that is, to the left, against the coil spring 3, thereby weakening the pressing force against the banknote 11. Further, when the motor is driven so that the pulley 12 rotates in the direction of arrow C, the pressing plate 1 moves forward, that is,
It moves to the right, and the pressing force against the banknote 11 increases.

However, after the pressing plate 1 moves to a position determined by the tension of the coil spring 3, the shaft 15 freely rotates while the pulley 12 is stopped by the action of the one-way clutch 40.

Therefore, elements 4, 12, 13, etc. constitute means for moving the pressing plate backward.

6 is the rotation speed V of the conveyor roller 10 via the belt 9.
This is a pulley on the driving side for stacking the paper money.When the rotation of this pulley causes the transport []-cra0 to be rotated in the direction of the arrow in the figure, and the banknotes are fed in the direction of the arrow F in the figure, the banknotes have already been stacked. The banknotes are fed between the first banknote and the conveyance roller 10 and stacked. Incidentally, 7a and 7b are paper sensors made of photo-ink lathers that detect that banknotes have been fed during this period.

Reference numeral 8 denotes a feed roller for feeding out the first stacked banknotes from below to the outside.By rotating in the direction of the arrow in the figure, the top banknotes are sent downward by the action of frictional force. It will be done.

FIG. 2 is a plan view of the main parts of the banknote stacking device shown in FIG.
A shaft 15 is supported by a bearing 22a installed inside the device main body 21a, and a gear 17 is mounted on this shaft 15.
are connected, and the gear 17 meshes with the other gears 18 and 19. l? 1-19 is connected to a pulley 21 via an electromagnetic clutch 20a. This pulley 21 is connected to another pulley 22 via a belt 23.

Reference numeral 24 denotes a motor that rotationally drives the pulley 22, and the rotational force of the motor 24 is transmitted to the shaft 15 when the electromagnetic gangway 20a is in an on state, that is, a connected state.

When the electromagnetic clutch 20a is off, the shaft 15 rotates freely regardless of the rotation of the seventh gear 24. Therefore, when the electromagnetic clutch 20a is off, the pressing plate 1 moves forward due to the tension of the coil spring 3 as shown in FIG. 1, and stops while pressing the bill 11 with the highest pressure.

Although FIG. 2 shows a portion where the motor 24 drives only the pulley 12 via the electromagnetic clutch 20a, this motor 211 is used as a drive source for a plurality of storage boxes. That is, the motor 24 is also connected to a plurality of other electromagnetic clutches, and by turning these electromagnetic clutches on and off as necessary, the driving force of the sweater can be input to the pulleys of the individual storage boxes. Can be done.

FIG. 3 shows the movement of the conveyance roller 10 and the detection switch 25.
In the figure, the press plate 1 applies pressure to the right to compress the banknote 11, and the conveyance roller 10 moves to the right at the same time. This situation is shown in Figure 1.
This is accomplished by moving the conveying roller 10 in the direction of arrow B. A connecting body 27 is connected to the rotating shaft of this conveying roller 10.
is supported, and a center 160 is supported at the tip of this connecting body 27.
An actuator 26, which rotates around the center, is in contact with the actuator 26. As the conveyance roller 10 moves to the right, the actuator 26 rotates in the direction of arrow F in the figure.
A light shielding plate 2 provided at the other end of the actuator 26
6a rotates.

As a result, the detection switch 25a consisting of a photointerrupter is turned on and detects that the banknote 11 is pressed with a pressure equal to or higher than a predetermined constant value.

FIG. 4 is a block diagram of the control section of the banknote stacking device, and the rest of the control section is controlled by a program of the CPU 30, and the control program is stored in the ROM 31 in advance. The RAM 32 is a memory used as a working area when executing the control program (as described above, a part of the memory is used as a register for a timer that measures the passage of a certain period of time).

The motor control circuit 34 is a circuit that controls forward rotation, reverse rotation, and stopping of the motor 24.

As shown in FIG. 3, the detection switch 25 detects when the conveyance roller 10 moves to the right from a predetermined position.
That is, it is a switch that detects a state in which the banknote 11 is pressed with a pressure higher than a predetermined pressure.

This detection switch is provided for each storage box and consists of a plurality of detection switches including 25a.

As shown in FIG. 1, the paper sensor 7 is a sensor that detects when banknotes to be newly stacked are sent in, and this paper sensor is assigned a number for each storage box.

As shown in FIG. 2, the clutch control circuit 35 inputs the rotational force of the motor 24 to the pulley 12.
? This is a control circuit for a plurality of electromagnetic clutches 20 that control I/O, and these are connected to I10 via 33 to CPU 3.
Controlled by 0.

Then, during the semi-boiling process before stacking banknotes, the CPU 30 determines that, among the plurality of storage boxes, the storage box that has reached the proper stacking suppressing force first, while the motor 2/I is on, ,
When the detection switch 20 of the storage box is turned off, the electromagnetic clutch 20 of the storage box is intermittently turned on and off through the clutch control circuit 35, and this state is maintained until the detection switch 20 of the last storage box is turned off. work to make you

FIG. 5 shows a processing procedure as a preliminary step before starting accumulation when there are two storage 'fI' (distinguished as storage box a and storage box 2), in which the flag fa is set in step n10.
The flag fb is set to "O" as the initial value, and the detection switches 25a and 25b for storage box a and storage box
1'' is set when the state of is turned off (steps n13 to n16), and will not be changed thereafter during this processing procedure.It is determined whether the pressing plate of each storage box has reached the appropriate accumulation pressing force. The judgment is made based on whether the flags fa and fb are 1" (step n17), and both fa and fb are 1".
If so, this processing procedure ends.

More specifically, first, in order to retreat the press plate of the storage box, the electromagnetic clutches 20a and 20b are turned on in step n11, and the motor is reversed in step r112. After that, steps n13 to n18 of checking the detection switches 25a and 25b at regular intervals are repeated, and the flags fa and f are checked.
When both b become 1'', the electromagnetic clutch 20a is activated in step n19.

Il runs in the background.

In the first order of processing in FIG. 6, if the flag fa is O'', that is, the press plate of the storage box is not yet at the appropriate accumulation suppression position, nothing is done and the appropriate accumulation pressure is reached, so wait (step n21). ).

The processing procedure after the flag fb becomes "1" is to check at regular intervals whether or not the motor is being reversed (steps n22 to n30), and when the motor is turned off, that is, when the storage box is pressed. If the plate is not yet in the proper accumulation suppression position, the electromagnetic clutch 20b of the storage box is moved in step n3.
