Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a means for guiding paper sheets in a device for separating accumulated canter leaves.

[Conventional technology]

In the conventional device, as described in Japanese Utility Model Application Publication No. 1-129145, the banknote guide of the separation device is fixed and only the feeding roller rotates to control the banknote conveying force. In this method, when the number of banknotes stored increases, the pressing force of the feeding roller becomes excessive, resulting in double feeding or
On the other hand, depending on the condition of the banknote, the pressing force against the surrounding guides becomes large, which increases the resistance force against conveyance of the banknote, and it is conceivable that a feeding error may occur.

Further, as described in Japanese Patent Application Laid-Open No. 12537/1983, a rotating auxiliary roller was arranged with its axis fixed. However, even in this device, when the number of banknotes stacked increases, the pressing force applied to the delivery roller becomes unstable, as in the above-described device, and the separation performance of paper sheets becomes unstable.

[Problem to be solved by the invention]

The present invention aims to improve the reliability of the above-mentioned separation performance.

That is, an object of the present invention is to provide a highly reliable paper sheet handling device by preventing the occurrence of feeding errors or double feedings that occur when separating paper sheets.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a storage means for storing paper sheets, a feeding means for feeding out the paper sheets stored in the storage means, and a feeding means for feeding out the paper sheets. a separating means for separating the accumulated paper sheets; and a first means for maintaining the posture of the paper sheets separated by the separating means and guiding the paper sheets during separation. The apparatus includes a guide means and a control means for controlling the position of the first guide means in accordance with the number of accumulated paper sheets or the magnitude of the pressing force applied to the paper feed means.

Further, it includes a detection means for detecting when the paper sheets that should originally be separated have passed, a second guide means that applies a conveying resistance force to the next paper sheet, and a and a control section for operating the second guide means.

[Function] With the above-described configuration, the storage means holds the paper sheets in good alignment, the feeding means applies a conveying force to the paper sheets and feeds the paper sheets toward the feeding means, and the feeding means holds the paper sheets that have been fed out. A conveying force is applied to the leaves to send them to the next element, and the separating means separates the accumulated paper sheets one by one. Since the guide means changes its position according to the number of sheets stored in the stack, the pressing force between the feeding means and the stack can be maintained appropriately. Thereby, the paper sheets to be separated can be given an appropriate conveying force from the separating means. As a result, paper sheets are prevented from being fed out incorrectly due to insufficient conveying force or double feeding due to excessive conveying force being applied.

Furthermore, the control means can change the position of the guide means in accordance with the pressing force of the stacked paper sheets applied to the feeding means, so that the conveying force to the paper sheets by the feeding means can be appropriately applied. Similarly, it is possible to prevent errors in feeding paper sheets or double feeding from occurring.

Further, since the detection means detects the position of the paper sheets to be separated, the timing at which the paper sheets being separated becomes independent of the guide means can be known from the output from the detection means. Based on the output from the detection sensor, the control unit can be operated to apply a resistance force to convey the sheet to the guide means. As a result, only the paper sheets to be separated are sent out, thereby preventing the occurrence of double feeding. [Embodiment] An embodiment of the present invention will be explained below with reference to Figs. 1 to 20. .

In addition, since the -next stacker 6 is constituted by a belt conveyance path and serves as both the -next stacker and the conveyance path, the conveyance route becomes simple and the apparatus can be made smaller and lower in cost.

Figures 2 to 10 show the 1000 yen recycling box 10 mentioned above. FIG. 2 is an explanatory diagram of the structure and operation of the holding plate 14 in the 10,000 yen recycling box 11 and the safe 12. FIG. As shown in FIG. 2, the holding plate 14 has four plates 14a, 14b, 1
4c and 14d, and a banknote 16a stored in a box 15.

The purpose is to partition and hold or move 16b. 3 to 5 schematically show the support structure and drive mechanism of the retaining plate 14.

The holding plate 14a passes through a gap in the notch 15a of the box 15 and is connected to a shaft 17, and the shaft 17 is rotatably engaged with a bearing 18. Further, a spring 19 is wound around the shaft 17, one end of the spring 19 is fixed to the shaft 17, and the other end is attached to the support base 2.
engaged with o. The support stand 20 is supported by a shaft 21 and a ball screw 22. The ball screw 22 is rotationally driven by a driving means (not shown). Holding plate 14c
are supported by substantially the same structural members as the retaining plate 14a, and the shaft 65. Bearing 66, spring 23. Support plate 24° guide shaft 25. The ball screw 26 is rotationally driven by another driving means (not shown). Holding plate 14
c passes through the notch 15b of the box 15 and is movable up and down, and has an intricate shape with the holding plate 14c so that they can move vertically without interfering with each other. Although the holding plate 14b is not shown, it has the same structure as the holding plate 14a, and the supporting plate 27 has the shaft 21,
It is supported by a ball screw 22. The retainer plate 14d has the same configuration as the retainer plate 14c (not shown),
The support plate 28 is connected to the shaft 25. It is supported by a ball screw 26. Further, the axial positions of the support plates 20.26, 27.28 are detected by ultrasonic sensors 2930, 31.32 set on another frame (not shown).

4 and 5 show a part of the drive mechanism for moving the support plates 20, 26, 27° 28 in the vertical direction. That is, taking the support plate 2o as an example, the clutch member 33 is rotatably supported by the support plate 20 and has an uneven surface on its surface, and the clutch member 33 is engaged with the ball screw 22.

The leaf spring 34 has one end fixed to the support plate 20,
The other end of the plate spring 34 is installed so as to engage with a recessed portion of the clutch member 33 to prevent rotation of the clutch member 33. The power switching member 35 has one end fixed to the support plate 20, and a shape memory element 35a arranged at the other end.
A heater 35b is wound around the shape memory element 35a. When the shape memory element 35a is heated by the heater 35b,
As shown in FIG. 5, the leaf spring 34 is driven by deforming into a pre-memorized shape and operates so that the leaf spring 34 does not come into contact with the clutch member 33. On the other hand, when the power to the heater 35b is cut off, the shape memory element 35a returns to the shape shown in FIG. 4 due to the restoring force of the leaf spring 34, and the leaf spring 34 engages with the clutch member 33 again.

This structure of the holding plate drive system enables the operation shown in FIG. 6. That is, when stopping the movement of the holding plate, the shape memory element 35a is turned on by inputting power to the heater 35b.
deforms, causing the leaf spring 34 to separate from the clutch member 33. As a result, even if the ball screw 22 rotates, the clutch member 33 only rotates, and the support plate 20 does not move upward or downward.

On the other hand, when driving the holding plate, the power to the heater 35b is cut off, so that the leaf spring 35 returns to its pre-deformation shape, and the leaf spring 34 and the clutch 33 are engaged. This results in
The rotational force of the ball screw 22 serves as the power for moving the support plate 20 up and down.

2 and 7 to 11 show the accumulated banknotes 16
A method of moving the holding plate 14 downward in order to release the holding plate 14 is shown. FIG. 2 shows the position of the holding plate when stacking and separating banknotes. That is, the holding plate 14a is in a position evacuated from the entrance path when the incoming banknotes are stacked, and the holding plate 14b holds the stacked banknotes 16a. The holding plate 14c guides the banknotes 16b to be separated downward, and the holding plate 14d is in a position retracted from the path of the banknotes to be separated.

FIG. 7 shows stacked banknotes 16a on a holding plate 14a.

The support plate 26 is shown being lowered while being clamped by the support plate 14b, and FIG. 8 shows the support plate 26 being raised. That is, the support plate 2
When the holding plate 14c is raised, the holding plate 14c also rises and interferes with the clamped banknote 16a, the shaft 21 rotates while being supported by the bearing 22, and the supporting plate 26 further rises and reaches the position shown by the two-dot chain line. As shown in FIG. 9, the restoring force of the spring 23 returns it to its original horizontal state. Next, the holding plates 14c and 1
4d moves to the same height as the holding plates 14a and 14b, and clamps the banknote 16a to restrain the banknote.

FIG. 10 shows the operation for subsequently raising the holding plates 14a, 14b and placing them in the same phase as the position shown in FIG.

In addition, the retaining plates 14a and 14b are moved upwards than the retaining plate 14C914d, but in this case, the retaining plates 14c
, 14d can be moved downward to obtain the same function.

In addition, in this mechanism, after separating all the banknotes 16b for separation and stacking the stored banknotes from the top again as the stacked banknotes 16a, the banknotes are moved to the separating side by a series of operations of the clamping plate 14. You can.

As a result, starting from the state where the stacked banknotes 16a are zero, all the banknotes can be separated, passed through the discrimination section 4, and stacked at the top again, so that each recycling box 10, 11,
Alternatively, the amount of banknotes in the safe 12 can be determined.

The above operation provides the following effects.

By connecting the rotational power of the ball screws 22 and 26 to the retaining plate 14 side using the clutch member 33, or by rotatably switching the power, the four retaining plates 1'4a, 14b, 1
Since 4c and 14d can be driven independently, it is possible to provide a small and low cost drive system for the holding plate.

In addition, since the banknotes 16a stacked in a complicated manner using the holding plate 14 can be moved to the separation unit 3 side as separation banknotes 16b with good alignment, the deposited banknotes can be used for withdrawal. It is possible to downsize a functional device.

Furthermore, as mentioned above, by using the holding plate 14, it is possible to perform the separating operation and the stacking operation at the same time, so for example, the number of banknotes in the 1,000 yen recycling box 10 can be stacked from above while being continuously separated. This makes it possible to count the number of stored sheets without having to prepare another empty box. That is, it is possible to provide a small, low-cost device that can count the number of banknotes in a safe or recycling box.

Moreover, this function is provided by the holding plates 14a and 14b.

It can be achieved even with three pieces of 14c. That is, the holding plate 14
d is in the position of FIG. 2 and is fixed, and the retaining plates 14a, 14b shown in FIGS. 7 to 10.

The three holding plates 14 are arranged to perform these series of operations so that the relative position of the holding plate 14c with respect to the holding plate 14d does not change.
It is clear that the operation can be performed while changing the position of.

12 to 16 show the bill stacking and separating mechanism and its operation. That is, the configuration and operation of the separating section 3 will be explained with reference to FIGS. 12 to 14.

3a is a feed roller for feeding forward the lowest banknote A of the stacked banknotes, which is arranged symmetrically on the left and right, the surface is made of a rubber material, and the roller rotates while being pressed against the stacked banknotes. . This rotation is driven by a pulse motor and another pulse motor (not shown).

3c is a feed roller that separates the banknotes A fed out by the feeding roller 3a one by one and sends them to the next conveying means 13, and is arranged at symmetrical positions on the left and right, and pulses arranged on the left and right respectively. It is driven by the motor at the required number of rotations.

Reference numeral 3b denotes a separation roller for separating two or more unrolled banknotes one by one, and is fixed and constructed of a rubber roller having a high coefficient of friction with the banknote. Separation roller 3b
are disposed opposite to the feed roller 3C at a position shifted in the axial direction, and are intertwined with each other in the radial direction.

37 is a first sensor for detecting the timing of passage of banknotes, and the same sensors are arranged at symmetrical positions on the left and right.
37a is a light emitting sensor, and 37b is a light receiving sensor. These sensors 37a and 37b are arranged on the side of the surface through which the banknote A passes and immediately behind the feed roller 3c,
It is placed so that the output will be output when it passes.

13b is a belt for pinching and conveying the banknote A, and a pair of belts are arranged to face each other.

13a is a guide roller for running the belt 13b. Although not shown, the belt 13b is driven to run by another drive roller. This belt 13b
The conveyance speed is approximately three times faster than the peripheral speed of the feed roller 3c.

Next, two sets of feed rollers 3C1, which are independent on the left and right sides,
A control system for the motor that drives the feeding roller 3a will be explained using FIG. 13.

The control circuit for the motors 36 and 43, as shown in FIG. 4, includes a first interface 38. Arithmetic unit 39 for performing arithmetic operations. A control table 40 for obtaining a target value to be given to the motor 36, which is the controlled object, based on the calculation result. A control unit 41 for controlling the motor 36 based on a target value. It consists of a second interface chair 42 for transmitting control signals to motors 36 and 43.

As a result, the passage timing of the separated banknotes is detected by the two left and right detection sensors 37, and this is input into the first interface 38, and the calculation unit 37 calculates the difference in the passage time of the banknotes between these left and right detection sensors. Then, depending on the magnitude of this passing time difference, the rotational speeds of the motors 36 and 43 are specified based on a predetermined control table 40 and are given to the control section 41. That is, the skew amount ΔΩ of the banknote is calculated from the time difference between the left and right passing timings,
In order to keep this skew amount below a certain value, the speed of the drive motor on the side where the banknote is leading is decelerated for a certain period of time as shown below.

That is, the motor speed at the time of detection by the sensor 37: ■ The time difference between the left and right passing timings: Δ is the deceleration time 2T.

On the other hand, the control unit 41 supplies the motors 36 and 43 with a control current for controlling the rotational speeds of the motors 36 and 43 via the second interface 42 .

That is, at the start of separating banknotes, the peripheral speeds of the feed roller 3a and the feed roller 3c are driven at approximately the same speed V.

A sensor 37 detects the skewed state of the banknotes being separated, and the motor on the preceding side of the skewed banknotes is decelerated to correct the skew.

Thereafter, after a predetermined period of time has elapsed, the feeding roller 35a is stopped before the banknote next to the banknotes being separated is brought into contact with the feeding roller 35a and fed out. After that, after a predetermined period of time has elapsed.

Again, the next banknote is separated by repeating the above-mentioned operation.

Note that the pressure control rollers 44 and 46 are connected to the shaft 45.4.
7, and the shafts 45 and 47 are supported by a cam equipped with a motor (not shown) so as to be able to move slightly upward and downward.

Further, the pressure control roller 46 is connected to an electromagnetic brake (not shown), and power is input based on the output of the detection sensor 37. That is, after the paper sheets to be separated by the first sensor 37 leave the pressure control roller 46 until the next paper sheet is separated, the electromagnetic brake is input, so that the pressure control roller 46 I'm trying to constrain the rotation of.

Further, a spring 51 is provided at the support portion of the feeding roller 3a, and the upper and lower positions of the feeding roller 3a are detected by a position detection sensor (not shown).

Next, the configuration and operation of the accumulation section 70 will be explained.

The stack guide 48 is rotatably supported around the axis of the roller 49. The conveyor belt 13b is wound around a roller 49 and is driven by a drive means (not shown). The sensor 5o is a second optical sensor and detects the position of the stacked banknotes.

When banknotes are stacked, the holding plate 14b moves downward, and the stacked banknotes move downward so that the optical path of the upper end detection sensor 50 of the stacked banknotes is not blocked by the stacked banknotes, and the upper part is always formed in a space.

On the other hand, banknotes sent by the conveyor belt 13b are guided and stacked by a stack guide 48.

FIG. 15 shows an accumulation operation flow by the accumulation section 70.

To prepare for the accumulation mode, first, a sensor (not shown) is used to confirm that no banknotes are accumulated in the conveyance path, etc., and the upper and lower phases of the four holding plates 14 are as shown in FIG. Check to see if the situation is correct. Next, it is checked whether there is a storage space for storing banknotes. Therefore, by moving the holding plate 14b up and down, the position detection sensor 50 detects that the upper end of the stacked banknotes is at a predetermined position.
is detected.

The following effects can be obtained by the above-mentioned operation of the accumulation section. By moving the position of the holding plate 14b, an entrance for banknotes can always be secured, so that one banknote can be stably stacked.

Next, the operation when separating banknotes will be explained with reference to FIG. 16. Here, a case will be described in which the separation operation is performed after the stacked banknotes 16a are moved to the separation side.

First, the holding plate 14d is retracted downward. Next, the vertical positions of the holding plate 14c and the pressure control rollers 44, 46 are set. That is, the number N of banknotes to be stacked is estimated from the position of the holding plate 14b at the end of the stacking operation.

In this case, the relationship between the position of the holding plate 14b and the number of stacked sheets N is determined in advance through experiments or the like.

Next, depending on the number N of accumulated banknotes, the pressure control port 4 is
The vertical positions of 4 and 46 are set by rotating the aforementioned cam to a preset position. On the other hand, the position of the holding plate 14c is set as follows. That is, when the accumulated number N is 299 sheets or less, the holding plate 14c moves up and down while referring to the output of the position detection sensor so that the position of the feeding roller 3a is at a predetermined position. Bare,
When the stacked number N is three or more, the position of the holding plate 14c is adjusted to the stacked number N so that excessive pressing force is not applied to the stacked bills and the posture of the stacked bills can be maintained. Accordingly, the robot gradually moves to a predetermined position. FIG. 17 shows the stacked number N and the holding plate 14.
It shows the position of c. The horizontal axis of the figure is the accumulated number of banknotes N,
and the shaft are located at the height direction H from the separation part of the holding plate 14c.
It shows. The separation section in this case indicates the lowest banknote position. That is, the holding plate 14c is set to be larger than the height when new banknotes are stacked.

The above configuration enables the following operations.

In the separating section 3, the stacked banknotes 16b are fed out by a roller 3a.
In this state, the feed roller 3a rotates and feeds out the banknote A between the foot roller 3a and the separation roller 3c, where the feed roller 3b rotates to separate the banknotes one by one and receive them on the next conveyance path. hand over. in this case,
The sensor 37 provided immediately after the separating section 3 removes the banknote A.
The transport cycle of banknotes A can be controlled before sending them to the next transport path 13. Further, since the conveyance speed is increased in the conveyance path 13, it is possible to convey the bills with a wider interval between the bills than when separating the bills.

On the other hand, in the stacking section 70 for banknotes B, the banknotes conveyed one by one are guided by the stack guide 48, and can be deposited in each recycling box 10, 11 or safe 12 in good alignment.

Further, since the positions of the pressure control rollers 44, 46 and the holding plate 14c can be controlled according to the number of stacked bills, it is possible to control the pressure applied to the feeding roller 3a with the banknotes.

Further, the pressure control roller can apply a conveying resistance force to the paper sheets until the next time the paper sheets to be separated are separated.

The operation of the separation mechanism described above produces the following effects.

Since the banknotes separated by the separation unit 3 are always conveyed for a period longer than a certain period and at intervals of banknotes, the banknote discrimination unit 4 located after the separation unit 3 can normally perform the banknote discrimination operation, and the banknote stacking can be performed normally. Even in the sections 7 and 70, banknotes can be stacked in an orderly manner without interfering with each other. Furthermore, even when the gate 63 is switched in order to guide the continuing banknote in another direction after the guide of the preceding banknote has been completed at the conveyance direction switching unit for the banknote B, the gate 63 and the banknote B do not interfere with each other and are guided. You can. Furthermore, since the banknote separation period in one separating section can be reduced, the ratio of the diameters of the feed roller 3C and the feeding roller 3a can be reduced, so that the separating section 3 can be made smaller.

Furthermore, by changing the positions of the pressure control rollers 44 and 46 according to the stacked number N, it is possible to optimally control the pressure from the banknotes applied to the feeding roller 3a, so that a stable banknote conveying force can be obtained. Separation can be performed stably. Furthermore, since the pressure control roller can apply a conveyance resistance force to the sheets to be separated next, double feeding of sheets can be prevented. Furthermore, by changing the position of the holding plate 14C in accordance with the number N of stacked sheets, an appropriate pressing force can be applied to the feeding means, so that separation can be performed stably with the same effect as described above.

Regarding the configuration and operation of the primary stacker 6 shown in FIG.
This will be explained using FIGS. 18 to 20.

The conveyance path 52 is composed of a pair of belts running opposite each other, and the upper side 52a of the belts extends forward. Further, a sixth detection sensor 53 for detecting passage of banknotes is provided near the end of the conveyance path 52. Conveyance path 5
4 consists of a pair of belts that are driven by a motor 61 and run opposite each other, and the upper side 54a of the belts is open to facilitate the entry of banknotes. On the other hand, the belt 54 on the lower side
b extends below the conveyor belt 52a.

Further, the tip portion 52b of the portion where the banknote is held by the conveyance path 52
The distance between the banknote and the rear end 54a of the portion where the banknote is held by the transport path 54 is smaller than the length of the banknote in the transport direction. The conveyance speed of this conveyance path 54 is controlled by a speed control means 60.

Furthermore, a conveying means 57 having opposing rollers is arranged at the forward end of the conveying path 54, and the conveying speed of this conveying means is set to be the same as the conveying speed (2) of the entire apparatus. The seventh detection sensor 58 is an optical sensor for detecting whether or not a banknote passes, and is provided between the conveyance path 54 and the conveyance means 57.

The solenoid 59 is provided in the middle of the conveyance path 54, and when the power is cut off, the solenoid 59 closes the conveyance path 54 as shown in FIG.
It is located at a position evacuated from the banknote conveying surface, and is arranged so as to come into contact with the rubber roller 56, as shown in FIG. 19, when the power is turned on. The solenoid 59 is driven by a solenoid drive control means 62. The solenoid 59 and the rubber roller 56 are located away from the belt position on the conveyance path 54, and are arranged so as not to interfere with each other. Further, the distance between the rubber roller 56 and the banknote clamping point 57a of the conveyance means 57 is larger than the banknote length L in the conveyance direction, and the amount of shift of the banknotes B and C stacked with a part of the banknotes deviated. and the banknote length L.

Next, a method of controlling the conveyance speed of the solenoid 59 and the conveyance path 54 will be explained. In normal mode, solenoid 59
The power source is turned off, and the conveyance speed of the conveyance path 54 is set to the conveyance speed of the entire apparatus. FIG. 20 shows the solenoid 59 and the conveyance path 54 during a transaction handling the -next stack mode.
This explains the method for controlling the conveyance speed. It is detected from the output of the sixth sensor 53 that the bill has entered, and after t1 seconds, the conveyance path 54 is driven at low speed Vz for t2 time.

As a result, the amount of overlap between the banknotes B that entered first and the banknotes that entered subsequently is controlled to a predetermined value, and the banknotes are accumulated in the conveyance path 54. Next, when separating this stacked banknote group, the conveyance path 54 is driven at a low speed v3,
After t8 seconds after it is detected from the output of the seventh sensor 58 that a banknote has entered, the conveyance path 54 is stopped and the solenoid 59 is energized at the same time. At this time, the leading edge of the bill B being separated is sufficiently clamped by the clamping point 57a of the conveyance means 57,
In addition, the rear end of the banknotes C to be separated is the conveyance path 54.
It remains in the rear end clamping portion 54C. After that, after t4 seconds, the conveyance path 54 is driven again at low speed v3,
The solenoid 59 is de-energized. That is, after 1+ seconds, the banknote B being separated is intensified by the conveying means 57, and a sufficient distance is maintained between the banknote B and the banknote C to be separated next.

Then, the above-mentioned operation is repeated until there are no more stacked banknotes.

The above operation of the primary stacker produces the following effects.

The primary stacked banknotes can be stacked one on top of the other with a certain amount of deviation from each other, and as a result, the separation means can be configured with a speed-increasing conveyance means, so a high-precision separator is not required as in the past. It can be made inexpensive and compact. In addition, since the solenoid can apply a conveying resistance force to the banknotes other than the banknotes that should originally be separated, each banknote can be reliably separated. In addition, since the primary stacker can be arranged on the belt, the single-sheet stacker can be arranged in any shape, allowing flexibility in the configuration of the entire apparatus.

〔Effect of the invention〕

According to the present invention, it is possible to prevent the occurrence of paper sheet feeding errors or double feeding, and therefore it is possible to provide a paper sheet automatic handling device that can achieve highly reliable separation performance.
