0 and safe 11.

Also, according to the customer's request, the first denomination box 9 and the second denomination box 9
The banknotes B stored in the denomination box 10 can be paid out to the deposit/withdrawal port 2 through the front/back reversing mechanism 7 with their surfaces aligned.

Next, the configuration of the impeller stacker section and separation mechanism described above will be explained using FIGS. 2 to 5.

In these figures, two feed rollers 20 are provided on a shaft 23 rotatably supported by a frame 22 and have a friction member 21 on a part of the circumference thereof. On both sides of the two feed rollers 20, stopper rollers 24 are disposed coaxially with the shaft 23, as shown in FIGS. 2 and 3. The stopper roller 24 is made of a material with a low coefficient of friction, such as metal. The feed roller 20 and the stopper roller 24 each have a groove 20A in the circumferential direction.

It has 24A. A gate roller 25 made of a friction member is disposed so as to fit into these grooves 20A and 24A. That is, the feed roller 2o and the gate roller 25. A stopper roller 24 and a gate roller 25 are arranged to overlap each other.

On the other hand, a timing pulley 26 is attached to one end of the shaft 23. This pulley 26 has a timing belt 2
It is multiplied by 7. This belt 27 is connected to a motor (not shown).

□ Thereby, the rotation of the shaft 23, that is, the feed roller 20 and the stopper roller 24 is controlled.

In the part between the feed rollers 20 and 20 of the shaft 23.

A gear 28 is fixed. This gear 28 engages with a gear 30 that is rotatably mounted on an arm 29 that is swingably mounted around the shaft 23. A cam 31 is attached coaxially to the side of the gear 30 and rotates together with the gear 30. Also.

On the free rotation shaft 32 attached to one end of the arm 29.

A rubber roller 33 and a pickup roller 34, which serves as a means for separating and feeding out banknotes and are made of rubber with a high friction coefficient and provide conveying force to the banknotes, are fixed to positions that engage with the cam 31. Cam 31 is.

When the gear 28 rotates once, it comes into contact with the rubber roller 33 by a predetermined rotation angle, thereby rotating the pickup roller 34. That is, when the shaft 23 rotates due to the action of the cam 31, the feed roller 20 and the pickup roller 34
will be driven in synchronization with. This pickup roller 34 is in contact with the longitudinal center of the banknote B when one banknote is separated and fed out;
The arm portion 29a of the arm 29 has a roller 72 as a first paper sheet deformation restricting means so as to come into contact with both sides of the arm 29 in the longitudinal direction.
It is located in The side rollers 72 are arranged at approximately the same position as the contact surface between the pickup roller 34 and the banknote, or at a higher position than the central pickup roller 3.
It is driven in the same way as 4. That is, the pickup roller 72 on the side of the arm 29 is connected to the gear 35, the cam 36, which is rotatably attached to the side of the arm 29. It is intermittently driven by a gear 38 fixed to the shaft 23 via the rubber rollers 3 and 7 in synchronization with the pickup roller 34 described above.

At the tip of the arm 29, in order to stably maintain the posture of banknote group B, in other words, when the pickup roller 34 comes into pressure contact with the banknote delivery side of the stacked banknote group, the banknote group is moved in the banknote delivery direction due to its bulging effect. A guide roller 39 is rotatably mounted as a second paper sheet deformation restricting means for preventing forward tilting. The guide roller 39 is located on the side opposite to the separation and delivery side with respect to the pickup roller 34, and comes into contact with the banknote B at a position approximately equal to or higher than the surface where the pickup roller 34 and the banknote B contact when the banknote is separated and fed out.

Pick up roller 34, roller 72 and guide roller 3
The swing position of 9 is the arm 29 which is swingably attached to the shaft 23.
This is obtained by detecting the amount of movement of the other end using the sensor 40. The output of this sensor 40 is applied through a control circuit 41 to a drive motor 42 of a ρ banknote pressing means, such as a stepping motor, which will be described later.

Arm 29 is coupled to a spring 44 that biases pickup roller 34, roller 72, and guide roller 39 to rotate counterclockwise.

By the action of this spring 44, the aforementioned pickup roller 34, roller 72, and guide roller 39 are moved to the safe 11.
When the banknotes B stored and accumulated in the storage portions of the denomination boxes 9, 10, etc. are brought into pressure contact and the banknote suppressing means described later is operated to push the banknotes B upward, the stopper 43 in contact with the arm 29 moves the banknotes to the upper limit position. is regulated. Also.

The arm 29 is equipped with a pickup roller 34 and the like.

A cam 45 rotated by another drive means and a roller 46 engaged with the cam 45 move the banknotes onto or above the stack in the storage section. Also, the frame 22 is attached to the arm 29.
A stopper 47 that also functions to hold down the accumulated banknotes supported by the
are connected by a link 48. Therefore, the stopper 47 rotates as the arm 29 swings. In addition,
It goes without saying that the pressing force on the banknote B may be applied by using its own weight instead of the spring 44.

In the vicinity of the aforementioned feed roller 20 and gate roller 25, there is provided paper sheet jamming release means for returning the banknote B that has been caught between the feed roller 20 and the gate roller 25 to the storage section at the end of banknote feeding. An arm 49 for pushing back banknotes is provided. This arm 49 is attached to a rotatable shaft 50. The shaft 50 is rotated by a driving means (not shown) such as a DC motor, and the rotation operation is performed after the feed roller 20 has rotated a desired amount in the opposite direction to the direction of rotation when feeding and separating banknotes. It swings from the position shown in FIG. 4 to the position shown in FIG. This swinging of the shaft 50 causes the arm 49 to push the bill B back into the storage section.

A shaft 51 parallel to the shaft 23 is rotatably supported on the frame 22 . This shaft 51 is driven by a motor (not shown). An arm 52 is arranged symmetrically on this shaft 51.
It is rotatably supported. A cantilever-supported shaft 53 is provided at the tip of the arm 52 . An impeller 54 serving as a bill receiving means is rotatably attached to this shaft 53. This impeller 54 consists of a gear 55 fixed to the shaft 51, an intermediate gear 56 provided on the arm 52, and the impeller 5.
4 and is rotated by meshing with a gear 57 attached integrally with the gear 57.

On the circumference of the impeller 54, there are blades 5 for receiving a plurality of banknotes.
4A are attached at equal intervals, and the banknotes B sent out from a conveyance path (not shown) can be held and conveyed by rollers 58 and 59 and pushed between the blades 54A of the impeller 54. Further, since the arm 52 is rotatable with respect to the shaft 51, the impeller 54 can swing in the same manner as the pickup roller 34. Movement of arm 52, i.e. impeller 54
The movement of the arm 52 is detected by a sensor, for example, a photosensor 60, provided opposite to the end of the arm 52.

The ON/OFF state signal of this photosensor 60 is the banknote B
It is used to control the amount of vertical movement of a push plate 62, which constitutes a banknote pressing means, which will be described later, in accordance with the amount of stacked banknotes. When the banknotes B are not accumulated in the storage section, the impeller 54 rotates downward and is located at the lower limit point regulated by the stopper 67, and the push plate 62 is located at the uppermost position. At this time, the photosensor 60 is in an OFF state. In this state, when the impeller 54 is driven to perform the receiving operation, as shown in FIG.
The conveyed banknotes B received by the impeller 54 are transferred to the impeller 5.
4 and as it rotates, it is fed into the storage section, and when it comes into contact with the stopper 47, it is removed from the impeller 54, and sequentially stacked on the push plate 62.

As a result, the banknotes B are sequentially accumulated in the storage section. When the banknotes B accumulate to a certain extent in the storage section, the impeller 54
is pushed upward by the accumulated banknotes B. When the impeller 54 rises to a specified position, the tip of the arm 52 that is linked to the rise of the impeller 54 comes off the photosensor 60 section, and the photosensor 60 is turned on. The ON state signal from the photosensor 60 is applied to a drive motor 42 of a banknote pressing means, which will be described later, through a control circuit 61 to lower the push plate 62 and lower the stacked banknotes.

As the group of banknotes descends, the impeller 54 rotates so as to descend toward the stacked banknotes. Due to this rotation, the arm 52 also rotates, and the tip of the arm 52 turns the photo sensor 60ttOFF again.
state. After the drive motor 42 is stopped by the OFF state signal of the photosensor 60, the banknotes are accumulated by the impeller 54 between the OFF state and the ON state of the photosensor 6o while repeating lowering and stopping of the push plate 62. It will be done. The impeller 54 is controlled to always swing within a substantially constant range. This causes the impeller S4 to.

The pressing force against the banknote is controlled by the detected value as the position of the impeller 54.

Next, the configuration of the bill pressing means described above will be explained using FIGS. 4 and 5. The push plate 62 receives and receives banknotes B accumulated in the storage section. This push plate 62 is the frame 22
It is supported by a guide shaft 63 and a screw shaft 64 provided therein and is driven in the vertical direction. That is, when the rotation of the drive motor 42 is transmitted to the screw shaft 64 by the belt 65, the screw shaft 64 rotates in the forward and reverse directions.
Move up or down. At this time, the pickup roller 34
When separating banknotes B, the sensor photo 40 is actuated by the swinging of the arm 29, and the position of the pickup roller 34 is controlled.

In other words, the height of the push plate 62 is controlled so that the pickup roller 34 is at an appropriate position relative to the feed roller 20 and gate roller 25.

Similarly, when banknotes B are stacked in the storage section as shown in FIG. 5, the position of the arm 52, ie.

□ The stacked amount of banknotes B is detected based on the signal from the boot sensor 60 that detects the position of the impeller 54, and when the banknotes B are accumulated and the impeller 54 is pushed upward, the push plate 62 is lowered to The position of the impeller 54 is corrected downward. As a result, the height of the impeller 54 is controlled within a certain range with reference to the position of the stopper 67 that determines its lower limit point. That is, the force that pushes up the impeller 54 depending on the amount of banknotes to be accumulated, or conversely, the pressing force that presses the banknotes B by the impeller 54 can be kept constant.

Next, the operation of the above-mentioned cash handling section will be explained.

First, the operation of separating and feeding out the banknotes accumulated in the storage section will be explained using FIG. 4.

When separating and sending out the banknotes B accumulated in the storage section, the arm 29 is set in a substantially horizontal state by the cam 45 and the roller 46 as shown in FIG. At this time, the guide roller 39 at the end of the arm 29 comes into contact with the stacked banknotes B in the uppermost tier, and suppresses the rise of the banknotes B on the side opposite to separation and delivery.

Further, the lateral rollers 72 similarly come into contact with both sides of the banknote B, thereby suppressing the rise of both ends of the banknote B in the longitudinal direction.

In this state, the drive motor 42 is driven and the drive belt 65 is
The screw shaft 64 is rotated through.

As a result, the push plate 62 rises, and the banknotes B in the storage section are gradually pressed against the pickup roller 34. Push plate 62
further rises, and the accumulated banknotes B hit the pickup roller 34 against the spring 44, and the stacked banknotes B hit the pickup roller 34 against the spring 44.
rises to the position set by the sensor 40,
The sensor 40 detects the position and stops the rotation of the drive motor 42. This causes the push plate 62 to stop rising. As a result, banknote B is set to a separable state6.
Next, when the feed roller 20 is rotated, the power from the gear 28 fixed to the shaft 23 is transmitted to the cam 31, and the rotation of the cam 31 causes the pickup roller 34 to rotate intermittently in synchronization with the feed roller 20. do. As a result, the uppermost banknote B pressed against the pickup roller 34 is sent to the separating section constituted by the feed roller 20 and the gate roller 25. At this time, when a plurality of banknotes B are fed into the separating section at the same time, the banknotes B are separated one by one by the frictional resistance of the gate roller 25 and sent out downstream.

The separation of banknotes B progresses, and the pickup roller 34 and push plate 6
When the amount of banknotes between 2 and 2 decreases, the pickup roller 3
4 is gradually rotated counterclockwise around the shaft 23 by the arm 29, so the arm 29 provided with the pickup roller 34 is similarly rotated counterclockwise. For this reason,
The signal from sensor 40 disappears. Then, the drive motor 42 operates again to push up the push plate 62 and press the bill B against the pickup roller 34 in the same manner as described above.

As described above, the pickup roller 34 can press the banknote B with a constant force, and can also keep its operating height always within a constant range with respect to the separating section composed of the feed roller 2o and the gate roller 25. Therefore, the banknotes B can be separated stably at all times without the occurrence of misfeed.

Next, at the end of the banknote separation and feeding operation, the topmost banknote in the storage section is transferred to the foot roller 20 and the gate roller 25.
It remains stuck between the two. In this state, the banknotes B cannot be received and stacked by the impeller 54, so the banknote B held between the feed roller 20 and the gate roller 25 is stored. The operation of pushing the bill back into the unit will be explained with reference to FIG. 4. First, it is driven by the drive motor 42.

The push plate 62 is lowered by a desired amount. Next, the arm 29 is rotated by the rotation of the cam 45, and the pickup roller 34 is rotated.
．． The roller 72 guide roller 39 and stopper 47 are retracted upward. Next, the arm 49 for pushing back banknotes is rotated counterclockwise from the position shown by the solid line in FIG. , feed roller 2
0 in the opposite direction to the rotation during separation. Through this series of operations, the bill B caught between the feed roller 20 and the gate roller 25 can be pushed back into the storage section, and the bill B caught between the feed roller 20 and the gate roller 25 can be released.

Next, when receiving and collecting the banknotes B that are sent one after another, as shown in FIG. from the top surface toward the impeller 54. Finally, the outer periphery of the guide roller 39 at the tip of the arm portion 29a of the arm 29 is positioned inside the blade 54A of the impeller 54, and the blade 54A of the impeller 54 is inserted into the blade 54A.
This prevents the banknotes B held between them from coming into contact with the guide rollers 39.

In this state, the stopper 4 that was retracted during the separation operation
7 rotates the feed roller 20 in conjunction with the rotation of the arm 29.
is set in front of the Further, the push plate 62 has the uppermost surface of the banknote B in contact with the impeller 54 .

When the impeller 54 is pushed upward and rotated around the shaft 51 by the rise of one banknote B that rises until it is pushed up, the photo sensor 60 disposed opposite to one end of the arm 52 is moved to a position above the impeller 54. Detect. The photosensor 60 applies its signal to the control circuit 61, so that the control circuit 61 applies a stop signal to the motor 42. This causes the push plate 62 to stop.

Through the above-described operations, the initial position of the push plate 62 for collecting and receiving banknotes B is determined regardless of whether there are banknotes or not. Next, the push plate 62 is lowered by a predetermined amount.

In this state, the receiving and stacking operation of one banknote B is started 6, that is, the impeller 54 rotates counterclockwise in FIG. 5 in synchronization with the transport of the banknotes B to be stacked, and the transport roller , 59, the banknote B is held by the impeller 54.
pushed inside. This banknote B is held by one blade 54A and rotated by the impeller 54 until it engages with the stopper 47. After that, one banknote B collides with the stopper 47 and leaves the impeller 54, and continues to be accumulated on the push plate 62 or the low-accumulation banknotes B in sequence. During this time, the push plate 62 is stationary, but when the amount of banknotes B accumulated increases and the impeller 54 is pushed upward, the arm 52 rotates clockwise to operate the photosensor 6o. A signal from the photosensor 60 activates the drive motor 42 to lower the pusher plate 62. When the pusher plate 62 is lowered, the arm 52 rotates counterclockwise and the photosensor 60 returns to its initial state. As a result, a banknote stacking state is formed with a weak pressing force that allows banknotes B to be pushed again between the impeller 54 and the banknotes B by the clamping force of the impeller 54 or by the clamping force of the impeller 54. Banknotes B can be continuously received and accumulated. That is, the impeller 5 follows the accumulated amount of banknotes B.
4 is rocking.

When the banknotes B accumulate to the extent that the impeller 54 is pushed up strongly,
The push plate 62 is lowered, and a state in which banknotes B can be stably received and collected can be maintained at all times.

Next, when the series of banknote receiving and collecting operations is finished and the banknotes B are to be separated and sent out again, the pickup roller 34, roller 72, guide roller 39 and stopper 47 move the banknotes B as shown in FIG. Since it advances to the upper surface, the banknote B can be fed out by this. Thereafter, the above-described separation operation will be repeated. In this separation operation, one banknote is prevented from rising and deforming on both ends of the banknote by the rollers 72 located on the sides, so that interference between the banknote end side and the guide at the banknote separating section that occurs during banknote separation can be reduced. I can do it. Furthermore, since the roller 72 mentioned above is rotationally driven,
A large conveying force can be applied to banknotes. Further, since the banknote is prevented from being deformed upward on the side opposite to separation by the guide roller 39, the posture of the banknote is kept constant and one banknote can be stably fed out toward the separation point. Namely.

Interference with other guide members etc. on the upper part of the banknotes can be weakened, and conveyance resistance can be reduced. As a result, misfeeding and skew of banknotes can be prevented.

Further, in the above embodiment, the side rollers 72 are
Although the roller 72 is rotationally driven by a drive system, it is also possible to adopt an idling support structure in which the drive system is not connected, as shown in FIG. In addition, by omitting the drive system, the device can be made smaller and lower in price.

Further, if the roller 72 is formed of a member having a small coefficient of friction with the bills, a fixed support structure may be used instead of the idling support structure, or a surface guide may be used instead of the roller to obtain the same effect as described above. be able to.

In addition, in the above-mentioned embodiment, the pickup roller 3
4. Roller 72. The positions of the guide roller 39 and the impeller 54 are each detected using a 1-position on-off control system, but they are configured using a 3-position on-off control system that detects the upper and lower limits at the same position.

The pressing force may be controlled, or a continuous control system may be configured to continuously control the positions and pressing force of the pickup roller 34 and impeller 54.

Furthermore, although the above-described embodiments have described a structure in which banknotes are stacked or separated and fed out in a horizontal direction, the present invention can also be applied to a case where the banknotes are in an upright position.

In each of the embodiments described above, a case has been described in which banknotes are handled as paper sheets, but it goes without saying that similar effects can be obtained with other paper sheets such as slips.

〔Effect of the invention〕

According to the present invention, when stacking paper sheets including folded or torn paper sheets by the impeller receiving guide means, the pressing force between the paper sheets and the receiving guide means can be kept constant, and one paper sheet can be stacked by the impeller receiving guide means. It is possible to improve the accumulation performance of industries.
