Description

Paper Stacking Device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper stacking device, and more particularly, to a paper stacking device suitable for continuously stacking paper such as banknotes having different dimensions.

BACKGROUND OF THE INVENTION [0002] An aggregation device using an impeller is known in a paper handling device, particularly a device for handling bills such as an automatic cash transaction device, including a device for depositing and withdrawing money. In particular, the input type integration device includes a device that integrates paper in a horizontal state and a device that integrates in a vertical state. The input type integration apparatus is generally a device that accumulates in any horizontal or vertical state, and is generally driven by rotating an impeller having an elastic wing and a roller or a conveyance belt facing the impeller so as to be positioned at a predetermined position above or in front of the paper accumulation section. A method of accumulating and storing a plurality of sheets is adopted.

Hereinafter, an example of the banknote accumulator of the conventional system will be described with reference to FIG.

Fig. 7 is a mechanism for accumulating banknotes used in the vertical state in the case of accumulating and withdrawing banknotes from the banknote entry and exit of the automatic teller machine. The banknote 220a conveyed from the upstream of the accumulator 200 is fed into the accumulation space 6 by the conveyance force of the contact point of the drive roller 1 and the opposing roller 202. As shown in FIG. The opposing roller 202 is driven integrally with the impeller 4 arranged coaxially. Since the impeller 4 rotates continuously with the opposing roller 202, the wing 4z of the contact part with the banknote 220a is deformed with the passage of the banknote 220a. By the restoring force of the blade 4z of the impeller 4, the banknote 220a is pressed against the accumulation guide 5 provided to face the impeller 4. The bill 220a fed into the accumulation space 6 along the accumulation guide 5 is protruded by the peripheral speed of both rollers at the time when the clamping by the drive roller 1 and the opposing roller 202 is out of the way. I'm going. In addition, the bill 220a is further accelerated and protruded by the restoring force of the blade 4z of the impeller 4.

The banknote 220a protruding into the accumulation space 6 has a tip portion collided with a stopper 211 provided at a position slightly above the banknote dimension on the accumulation space 6, thereby restricting the position of the banknote tip. By regulating the position of the front end of the banknote, the rear end of the banknote strikes in the direction of the supporting plate 9 by the rotation of the impeller 4 so that the banknotes are accumulated one by one.

Moreover, when the back end part of a banknote hits by the impeller 4 one by one, the space of the banknote entrance of the accumulation space 6 is ensured, and interference with the next banknote can be avoided.

As described above, the conventional aggregation device is suitable for accumulating banknotes having the same dimensions in the conveying direction, and there is an advantage that it can be reduced in size and inexpensively because no control is necessary. However, when accumulating banknotes with different dimensions, there is a problem disclosed below.

In the case of accumulating banknotes with small dimensions in the conveying direction, the impeller 4 does not touch the back end of the banknote when the banknote tip collides with the stopper 211, so that the banknotes move unstable in the stacking space and can be accumulated normally. There will be no. In the worst case, the banknote may be blocked by interfering with the next banknote.

In order to cope with such a phenomenon, the paper-stacking apparatus disclosed in Unexamined-Japanese-Patent No. 9-278254 is proposed. Independent of the rotating impeller, they are provided with a deceleration means for slowing down the transfer speed of the banknote near the banknote clamping part, and forcibly hits the rear end of the decelerated banknote by the impeller even if the leading end of the banknote being brought in does not touch the case. It is a paper-type accumulator which accumulates continuously, falling and avoiding a collision with the next brought-in banknote.

However, since the deceleration means always acts on the banknotes that have been carried in, the deceleration degree is varied depending on the banknote state, and it is difficult to speed up when trying to secure an interval with the next banknote. In addition, since the impeller blade is deformed by the passage of the banknote, even if the banknote is decelerated by the deceleration means, the banknote sticks out to the case side by the restoring force of the blade, and in the case of a small banknote, the back end of the banknote cannot be hit by the impeller, and thus it is normal. It becomes difficult to accumulate.

In recent years, the compactness and low price of paper stacking devices have become an issue of competition. Under such circumstances, the input type integrated device is expected to be smaller and lower in cost than other integrated devices. However, in the device according to the prior art, in particular, when papers of different dimensions are integrated, the alignment of papers in the integrated space is deteriorated, which increases the risk of interference between the loaded paper and the integrated paper, that is, the performance of the integration operation is reduced. Therefore, it was difficult to realize as an integrated device of paper having different dimensions.

SUMMARY OF THE INVENTION An object of the present invention is to provide a high-performance paper sheet accumulating device that is compact in a simple configuration even for paper having different dimensions.

In order to achieve the above object, the paper stacking device according to the present invention is a paper stacking device in which papers that have been separated and conveyed are accumulated by rotation of an opposite roller and rotation of an impeller, wherein the stacking device transfers paper into the stacking device. The drive roller and the driven roller are driven by being pushed and driven by the drive roller, an impeller having coaxial and axially spaced apart driven driven rollers and spaced apart in the axial direction, and driven independently of the driven roller, drive rollers and driven rollers. An integrated guide extending from the contact point of the paper downstream to the conveying direction of the paper and guiding the paper so as to face the blade of the impeller through the paper, and by the contact resistance force by the blade and the integration guide of the impeller in a predetermined rotational phase, Stop the paper entering the accumulation space where papers are guided by the accumulation guide. After that, the impeller is rotated by a predetermined amount so that the paper is accumulated one by one.

This paper sheet accumulating device may be used as a bill accumulating device when it is applied to the banknote deposit / exit port, the deposit cassette, and the discharge cassette in an automatic cash machine.

The action of the impeller on the paper by the blades is controlled to rotate the impeller's blades through the paper to cause the integration guide and contact resistance to the paper at a predetermined rotational phase, so that the conveying speed of the papers guided into the paper stacking device is decelerated. It acts to stop.

Then, when the papers to be conveyed impart contact resistance force by the blades and the integration guide of the impeller stopped at a predetermined rotational phase, the positions of imparting contact resistance force to the papers by the impeller blades and the integration guide are at the driving roller and the driven roller. It is good also as a structure set higher than a pressure contact point, and in that case, the impeller rotates a predetermined amount in order and generally gives the contact resistance with respect to the paper which entered into the integrated space from below, and is generally vertically sequentially. Accumulate.

In addition, the blade of the impeller has a rotational phase overlapping with the integrated guide provided so that the first wing located downstream of the conveying direction from the contact point of the driving roller and the driven roller to face each other via the paper is a position to impart a contact resistance force against the paper. It may be a configuration.

The elastic blade of the impeller of this invention may be a radial structure and the structure arrange | positioned in a different pitch. The impeller may consist of a braking elastic wing for stopping the paper and an elastic wing for securing a space for accumulating papers. In this case, except the part with the largest pitch of an elastic blade, the other part may be the same pitch. In other words, the elastic blades are not arranged at the same pitch over the entire perimeter of the impeller, the blades for imparting contact resistance to the papers and the blades for striking the rear end of the papers may be arranged at different pitches. The pitch between the braking elastic wing and the space securing elastic wing is the pitch of the braking elastic wing and the space securing elastic wing on the upstream side of the paper sheet. What is necessary is just to make it larger than the pitch with the said space | wing clearance elastic wing.

In addition, the shape of the front-end | tip part of an elastic wing | blade may be a shape in which the front-end | tip part of the adjacent wing | blade continued.

And a means for fastening the elastic blades of the impeller to the upstream conveying path of the paper sheet clamping point, which is the pressure contact point between the driving roller and the driven roller, to secure the conveyance path of the paper at the stop position of the impeller during the integration operation. The configuration may be.

The impeller of the present invention may be controlled to rotate from the stop position every time the sheet of conveyed paper is accumulated one by one, and the blades for striking the rear end of the sheet of paper to impart the contact resistance to the sheet of paper and the sheet of paper to be disposed. It may control so that it may rotate 120 degree suitably instead of half rotation by this. That is, with respect to the blade that generates contact resistance in cooperation with the integration guide for the papers to be accumulated, the rotation phase is controlled by a rotational phase in which the papers subjected to the contact resistance to accumulate to accumulate are actuated after the contact resistance is released. Needs to be. For that purpose, it is preferable to comprise the sensor which detects the passage of the conveyed papers, and to control the rotation phase of an impeller based on the detection result of a sensor. Moreover, it is preferable to detect the front-end | tip of the paper conveyed by the sensor, and to control the rotation phase of an impeller.

In order to accumulate papers by the present method with good alignment, it is important that the stop position of the rear end of the paper is in a predetermined range regardless of the shape and state. Therefore, it is necessary to appropriately control the rotational phase of the impeller so as to impart the contact resistance force generated by the integrated guide and the impeller blades to the paper. In addition, the integration guide may have a braking part for increasing the contact resistance with the paper, where the paper guide cooperates with the wings of the impeller to impart the contact resistance with the paper. Further, a convex portion having a vertex is formed between the pressure contact position of the driving roller and the driven roller, and the impeller and the braking portion of the integrated guide, in the shape viewed from the axial direction of the integrated guide, and the papers come into contact with the driven roller. When the paper is in contact with the sheet, the paper may be separated from the braking section.

The integrated guide and the driven roller of the present invention may slightly overlap the integrated guide and the driven roller on the downstream side in the conveying direction of paper rather than the contact point of the driving roller and the driven roller as viewed from the axial direction of the roller. In this way, the paper can be pressed against the driven roller during the conveyance of the paper, and the conveying force can be imparted to the paper even after the paper passes the sandwiching point.

In the driven roller of the present invention, the friction coefficient of the outer circumferential surface of the driven roller or at least the outer circumferential surface of the side surface may be larger than the friction coefficient of the integration guide. And the structure which provided the groove in the axial direction on the surface of a driven roller, or provided the notch of groove shape in the outer peripheral surface which contact | connects the side surface of the driven roller at least in the side which faces the integration guide may be sufficient.

According to the present invention, even when papers having different dimensions have been mixed and conveyed, the paper is stopped in the accumulator by the contact resistance between the brake elastic blade and the integrated guide, and then the paper is accumulated by rotating the impeller blades. The ends of the paper can be aligned and integrated.

Hereinafter, an embodiment of the paper sheet collecting device of the present invention will be described in detail with reference to Figs.

1 is an embodiment of a paper sheet stacking device of the present invention for stacking paper in a vertical state. An integrated device for accumulating papers in a vertical state is easy to configure and excellent in practicality as compared to an integrated device for accumulating paper in a vertical state. Hereinafter, an integrated device which integrates in a vertical state will be described.

Fig. 1 shows a paper stacking device in a state of waiting for carrying bills. As shown in the figure, the drive roller 1 which is always rotated by the drive means which is not shown in figure, the driven roller 2 driven by pressure by the drive roller 1, and the sensor which detects the passage of paper ( 3) and a plurality of coaxially spaced apart driven shafts in the axial direction, and are provided so as to face the impeller 4 and the impeller 4 which are driven independently by a driving means (not shown) and overlap each other. An accumulation guide 5, an accumulation space 6 guided by the accumulation guide 5 to accumulate paper, an auxiliary conveying means 7 for conveying paper to the accumulation apparatus, and a conveyance guide for guiding the conveyed paper; (8), a base plate (9) forming an integrated space (6) together with the integrated guide (5), a bottom plate (10) serving as an integrated surface of paper, and an upper plate provided at an upper portion of the integrated space (6). It consists of (11). The accumulated banknote 20 is integrated along the support plate 9.

Moreover, although the sensor 3 uses the pass sensor which optically detects the passage of paper and turns it off, you may use what kind of sensor as long as it is a sensor which can detect the passage of paper noncontact.

The elastic blades of the impeller 4 are radially and at least partially arranged at different pitches using a flexible material, and a wider pitch portion is shown in FIG. It is controlled to stop at the rotational phase to become.

Here, radial means that the elastic blade extends radially from the boss of the impeller, and the shape of the tip of the elastic blade is not regulated. That is, it may be a shape in which the tip portion of the elastic blade is connected. In addition, although the other pitch shows that the adjacent elastic blades are another pitch, other parts except the part with the largest pitch of an elastic blade may be the same pitch.

In other words, the different pitch in the present invention means that the spacing of the elastic wings in one group is different from the spacing of one group of elastic wings for stopping and stacking paper and the other group. It doesn't matter whether the elastic wings are the same or different apart.

In addition, in the stop position of the impeller 4 mentioned above, the integration guide in which the at least 1st blade | wing 4a which is downstream from the pressure contact point of the drive roller 1 and the driven roller 2 provided with the impeller 4 was provided. There is also a rotational phase overlapping with (5). In addition, in the drawing, the elastic blade 4a overlapping the integration guide 5 is a brake elastic blade 4a having a function of stopping the paper, and the braking elastic blade having the same function at a position symmetrical 180 degrees ( 4b) is arranged. The elastic blades except for the braking elastic blades 4a and 4b move and accumulate the paper stopped in the integrated space 6 toward the backing plate 9, and at the same time, secure the entry space of the next paper to prevent clogging due to the interference of the paper. prevent.

In Fig. 1, the impeller 4 has two gathering portions of elastic wings composed of three pieces of elastic wings in the circumferential direction, and the number of pieces of elastic wings per one place is not limited to three pieces. Many longevity is OK. In the case of increasing the number of elastic wings per one place, the elastic wings for securing the space near the braking elastic wings 4a and 4b also function as braking paper. In the paper stacking operation, in order to prevent the elastic wing for securing the space of the impeller 4 from protruding in the conveying path of the paper by the vibration at the time of stopping, the conveying guide 8 does not cause the elastic wing. The guide part (not shown in detail) which hangs and fixes is provided. [In Fig. 1, the elastic blade on the upstream side in the conveying direction of paper is bent by the guide portion with respect to the elastic blade 4a.]

FIG. 2 is an explanatory view for explaining the arrangement of the rollers when the paper sheet accumulating device shown in FIG. 1 is viewed from the inclined upper side of the supporting plate 9 side from the inlet of the paper into the accumulating space 6. In Fig. 2, components common to those in Fig. 1 are given the same reference numerals. 2, the arrangement | positioning which the integration guide 5 and the elastic blade 4a which give a paper | braking action to a paper overlap each other is demonstrated in detail.

The integration guide 5 and the elastic blade 4a are arrange | positioned opposingly at the position shifted in the axial direction. The conveyed paper is sandwiched by the drive roller 1 and the driven roller 2, and is conveyed forward from the rear of FIG. The drive roller 1 so that the drive roller 1 and the driven roller 2 can convey in the case where paper has shifted and conveyed in the axial direction (left-right direction of FIG. 2) of each roller with respect to the paper-type accumulation apparatus. ) And the driven roller 2 are arranged at the center side.

The elastic blades 4a of the impeller 4 provided in the center are disposed so as to overlap with the accumulation guide 5a provided between the drive rollers 1. When the paper is conveyed by the drive roller 1 and the driven roller 2, the elastic blade 4a and the integration guide 5a of the impeller 4 provided in this center give a contact resistance force to the paper.

The integration guide 5a should just have a stackable height which gives contact resistance with respect to the stationary elastic blade 4a.

The accumulation guide 5 disposed outside the drive roller 1 is disposed so as to overlap with the elastic blade 4a of the impeller 4. When the paper is conveyed by the drive roller 1 and the driven roller 2, the elastic blade 4a and the integration guide 5 of the impeller 4 provided in the left and right impart a contact resistance force to the paper. Similar to the integration guide 5a, this integration guide 5 has at least the height which can overlap with the stationary elastic blade 4a.

The integration guides 13 and 14 which are not shown in FIG. 1 are arrange | positioned axially shifted from the impeller which has the elastic blades 12a and 12b. These integration guides 13 and 14 and the elastic blade 12a are members for improving the integration performance of the paper to be integrated and stabilizing the paper. The accumulation guides 13 and 14 appropriately suppress the deformation of the conveyed paper. The accumulation guides 13 and 14 and the elastic blades 12a may be disposed at such a position as to be able to suppress the deformation of the conveyed paper, and the integration guides 13 and 14 may be arranged more than the stationary elastic blades 12a. It is good to have height to high position.

In the paper stacking device to which the present invention shown in Fig. 2 is applied, a plurality of impellers and stacking guides are provided. In order to stably hold the conveyed paper with the stacking guide and the elastic vane, the paper length direction (in this embodiment) It is preferable to give a strong contact resistance force to the substantially center portion of the paper near the center of gravity in the left and right directions in the figure. Therefore, in the present embodiment, at least the integration guide 5 and the integration guide 5a and the elastic blade 4a (or the elastic blade 4b) are enlarged so that the other integration guides 13 and 14 and the elastic blade ( 12a) (or the elastic blade 12b) imparts a stronger contact resistance than the contact resistance applied to the paper. It is also effective to make the flexural rigidity of the elastic vanes 4a and 4b higher than the flexural rigidity of the elastic vanes 12a and 12b.

And in order to concentrate the contact resistance force on the guide part of the center side, and to suppress a deformation | transformation of paper suitably and to improve integration performance, the impeller which has the elastic blades 12a and 12b is different from the structure of the impeller 4 It is also effective. Specifically, although three pieces of elastic wings are provided for each assembly portion of the impeller 4 shown in Fig. 1, the space on the opposite side to the braking elastic wings 4a (or the elastic wings 4b) is secured. It is the structure which made one elastic wing per one place except the dragon elastic wing, and made them the elastic wing 12a, 12b. With such a configuration, it is possible to appropriately suppress the deformation of the paper and to shift the integration timing of the both ends of the deformed paper, and to perform better alignment.

2, the elastic blades of each impeller 4 show the elastic blade 4a and the elastic blade 4b, and the illustration of another elastic blade is abbreviate | omitted.

3 shows a state immediately after the paper 20a enters the integrated space 6. As shown in the figure, the paper 20a entering the integrated space 6 is pressed against the driving roller 1 and the driven roller 2 to impart a conveying force. At this time, since the impeller 4 is stopped at a predetermined rotational phase, the paper 20a is moved by the conveying force of the driving roller 1 and the driven roller 2 along the accumulation guide 5 of the impeller 4. The braking elastic blade 4a is pushed up to enter the integrated space 6. The entry of the paper 20a along the accumulation guide 5 is because the braking elastic blades 4a overlap with the accumulation guide 5 so that the paper 20a entering the accumulation space 6 has the elasticity for braking. This is because the pressure is applied to the integration guide 5 by the blades 4a.

While the paper 20a is sandwiched between the drive roller 1 and the driven roller 2, the paper 20a is larger than the contact resistance force that passes through the overlapping portions of the brake elastic blades 4a and the integration guide 5. ), The paper 20a enters the integration space 6 along the integration guide 5 because of the large conveying driving force.

4 shows a state where the paper 20a is stopped in the integrated space 6. As shown in the figure, the conveyance force disappears when the rear end of the paper 20a passes through the clamping portion of the driving roller 1 and the driven roller 2, so that the paper 20a is provided with a braking elastic wing 4a. It slows down and stops by the contact resistance force which passes through the overlap part of the integration guide 5. Moreover, if the contact resistance force at the time of passing through the overlapping part of the braking elastic blade 4a and the integration guide 5 is small, the paper 20a will pass through the impeller 4 part by the kinetic energy at the time of leaving the clamping part. Do it.

For this reason, the rigidity of the brake elastic blades 4a and 4b and the rotational phase at the time of the stop of the impeller 4 are determined corresponding to the paper 20a to handle.

5 shows a state in which the paper 20a is accumulated. From the state of FIG. 4, the impeller 4 is rotated halfway to release the contact resistance force, and as shown in FIG. 5, the paper 20a is moved along the bottom plate 10 of the integrated space 6, so that the integrated space is released. The other braking elastic blade 4b of the impeller 4 stops at the position overlapped with the accumulation guide 5 in preparation for the subsequent entry of paper while accumulating on the backing plate 9 side of (6). Moreover, the timing which rotates the impeller 4 assumes that the paper 20a is stopped after a fixed time passes after the rear end of the paper 20a passes through the sensor 3. The setting of the fixed time needs to be longer than the time necessary for the rear end of the paper 20a to pass after passing through the sensor 3 and to stop. And the setting method of a fixed time is the same also if the position of the sensor 3 shift | deviates from a conveyance direction except the case where the stop timing of the paper 20a is integratedly measured.

In this manner, since the impeller 4 is rotated to move the paper 20a after the paper 20a is stopped, the paper 20a does not pop up, and thus the paper 20a can be accumulated without the top plate 11 of the integrated space 6. The rear end of the paper 20a can be arranged on the bottom plate 10 to be integrated. Moreover, even when papers having different dimensions are mixed and conveyed, the impeller blades act on the rear ends of the papers having small dimensions, and the rear ends of the paper can be arranged and accumulated on the bottom plate 10. Moreover, by repeating these operations one by one, even paper having different dimensions can be aligned and integrated well.

Fig. 6 is a control flowchart of the integration operation of the paper shown in Figs. 1, 3, 4, and 5;

In step 100, the integrated device is initialized, the impeller 4 is stopped at a predetermined rotational phase as shown in FIG. 1 to prepare for integration, and the drive roller 1 is continuously rotated.

In step 101, the end of conveyance of paper is confirmed. If there is no conveyance end signal, the process proceeds to step 102, and if there is a conveyance end signal, step 106 respectively. The conveyance end signal is, for example, when the banknote is separated from the banknote storing part in the banknote dispensing machine and withdrawn, when the banknote is separated from the banknote storing part, the number of bills counted when passing through the banknote and the sensor 3 This signal is output when is matched. In consideration of the case where the overlapped and separated paper is separated during conveyance or when the normally separated paper is overlapped during conveyance, the conveyance end signal is output after a certain time elapses without any problem in the accumulation operation.

In step 102, the tip of the paper 20a is detected by the sensor 3. After detecting the tip of the paper 20a, the flow proceeds to step 103.

In step 103, the rear end of the paper 20a is detected by the sensor 3. After detecting the rear end of the paper 20a, the process proceeds to step 104.

In step 104, the paper 20a waits until it stops by the contact resistance of the overlapping portion of the braking elastic blade 4a or 4b and the integration guide 5.

In step 105, the impeller 4 is rotated by a predetermined amount to release the contact resistance, while the paper 20a is moved along the bottom plate 10 of the integrated space 6, and the supporting plate 9 of the integrated space 6 is removed. Integrates in parts. After the impeller 4 has been rotated by a predetermined amount, the braking elastic blades 4a or 4b of the impeller 4 stop in the rotational phase overlapped with the integration guide 5 in preparation for the entry of subsequent paper. The amount of rotation of the impeller 4 is not limited, but in the configuration of the present embodiment, it is preferable to control at half rotation (180 degrees) so that the next braking elastic blade overlaps with the integration guide 5 for speeding up. As the driving means of the impeller 4, it is preferable to use a pulse motor for high speed positioning or low cost. After rotation of the impeller 4, it returns to step 101 and confirms completion | finish of conveyance of paper. In step 106, the stop processing of the drive roller 1 is performed, and the integration operation ends.

Further, another embodiment of the paper sheet stacking device of the present invention will be described in detail with reference to Figs.

FIG. 8 is a view in which the shapes of the braking elastic blades 4a and 4b of the impeller 4 shown in FIG. 1 are changed. As shown in Fig. 8, the elastic blade is radially attached to the boss of the impeller, and the braking elastic blades 4a and 4b of this embodiment are adjacent to the braking elastic blade and the braking elastic blade in Fig. The tips of the elastic blades are connected to each other to form braking elastic blades 4a and 4b. By setting it as such a shape, the braking force acting on the paper of the elastic blade for braking can be improved.

The elastic wing of the shape which connected the front-end | tip part of the adjacent elastic wing is called a loop-shaped elastic wing. Loop-shaped elastic wings can improve the integration performance as well as the braking force.

For example, when the braking elastic wing is not a loop type elastic wing, the paper has been conveyed in one side, so that the paper end portion comes out of the braking elastic wing when the paper is stopped. In this case, in the integration operation, in the step of releasing the contact resistance by rotating the impeller, the braking elastic blades move and accumulate the paper toward the support plate 9 at the end of the paper away from the braking elastic blades. When the type elastic blade is used for the braking elastic blade, the integration timing in the width direction of the paper is shifted so that the integration performance can be prevented from being lowered.

Moreover, the impeller 4 which has a loop type elastic blade needs to be arrange | positioned only in the center side which fully requires contact resistance force in an axial direction.

Then, as shown in Fig. 8, the stacking guide 5 is slightly overlapped with the driven roller 2 on the downstream side of the paper sheet clamping point, which is the pressure contact point between the driving roller 1 and the driven roller 2, during conveyance. It is possible to press the paper to the driven roller 2, so that the conveying force can be imparted to the paper even after the paper has passed the pinching points of the papers that are the pressure contact points. By setting it as such a structure, the stop position precision of a paper improves.

8, the braking part 5b is provided in the vicinity of the position which opposes each other in the outer peripheral part of the impeller 4 of the integration guide 5. Moreover, FIG. The function of the braking section 5b will be described later.

FIG. 9 shows a state immediately after the paper 20a enters the integrated space 6 in the configuration of FIG. As in the state of Fig. 3, the braking elastic blade 4a and the integration guide 5 act to impart contact resistance to the paper 20a.

When the paper 20a enters into the accumulation space 6 further from the state of Fig. 9, and the rear end of the paper 20a passes through the clamping portion of the driving roller 1 and the driven roller 2, the conveying force at the clamping portion Disappears. However, as shown in Fig. 10, the rear end portion of the paper 20a is in contact with the driven roller 2, whereby the force for the brake elastic blade 4a to press the paper 20a is the accumulation guide 5. It is applied with the apex of the convex part provided in the support point. This force generates a force that pushes up the rear end of the paper 20a from the driven roller 2. As shown in Fig. 12, the force for pushing up the paper 20a can be increased by using the outer peripheral portion 2a of the driven roller 2 as a material having a large friction coefficient or by providing the groove 2b in the outer peripheral surface. Moreover, it is preferable that the groove | channel 2b is missing in the outer peripheral side edge part 2c.

The state at the time of stopping the paper 20a is shown in FIG. The braking portion 5b made of a higher frictional resistance member than the accumulation guide 5 acts as a convex portion of the accumulation guide 5 so that the conveyance resistance force acts when the rear end of the paper passes the convex apex of the accumulation guide 5. It is downstream of the vertex of a shape, and is provided in the integrated space 6 side edge part. With such a configuration, since the paper is pressed against the accumulation guide 5 by the braking elastic blade 4a, the paper can be stably stopped due to the contact resistance force and the transfer resistance force by the braking portion 5b. .

Fig. 13 aims to improve the processing speed of paper by setting the minimum operating angle of the impeller 4 during the accumulation to 120 degrees. To this end, the braking elastic wing and the space securing elastic wing are provided in three places in the circumferential direction. The other configuration is the same as the embodiment described in FIG.

In the configuration of FIG. 13, the space securing elastic wing of the impeller 4 is made larger than the diameter of the loop type elastic wing so that the space securing elastic wing bounces off the conveying path when the impeller 4 stops rotating. To prevent it from coming out.

6 illustrates a control flow in which the impeller is rotated after detecting the rear end of the paper, but it is also effective to perform the rotation control of the impeller after the front end of the paper is detected. However, in order to secure the performance by performing control as shown in Fig. 6 by detecting the tip of the paper, it is necessary to shift the sensor position.

FIG. 15 is a configuration in which the sensor 3 of the integrated device shown in FIG. 13 is moved upstream of the conveyance path. Other configurations are the same as those described in FIG.

FIG. 16 is a control flowchart of the integration operation in detecting the front end of the paper in the configuration of FIG.

In step 300, the integrated device is initialized, the impeller 4 is stopped at a predetermined rotational phase as shown in FIG. 15 to prepare for integration, and the drive roller 1 is continuously rotated.

In step 301, the conveyance of paper is confirmed. If there is no conveyance end signal, the process proceeds to step 302, and if there is a conveyance end signal, step 306 respectively. The conveyance end signal is, for example, when the banknote is separated from the banknote storing part in the banknote dispensing machine and withdrawn, when the banknote is separated from the banknote storing part, the number of bills counted when passing through the banknote and the sensor 3 This signal is output when is matched. In consideration of the case where the overlapped and separated paper is separated during conveyance or when the normally separated paper is overlapped during conveyance, the conveyance end signal is output after a certain time elapses without any problem in the accumulation operation.

In step 302, the sensor 3 detects the presence or absence of paper. At the time of step 302, at the time of step 302, since the paper has not yet been conveyed, the paper proceeds to step 303 without detecting the paper.

In step 303, the sensor 3 detects the presence or absence of paper, that is, the front end portion detection. After detecting the tip of the paper, the process proceeds to step 304.

In step 304, time adjustment according to the installation position of the sensor 3 is performed. Since the position where the sensor 3 is installed varies in design freedom depending on where the integrated device is installed, the installation position of the sensor 3 detecting the paper tip is suitable for the rotation of the impeller 4 performed in the next step. If it is in place, this step 304 may not be necessary.

Step 304 is installed to measure the time until the position of the tip of the paper moves to the proper place for the impeller 4 to rotate in the next step, when the installation position of the sensor 3 detecting the tip of the paper is far away. do. When the installation place of the sensor 3 which detects the front-end | tip of a paper is far, when time according to the position of the sensor 3 passes, it will move to next step 305. In reality, the sensor 3 is preferably installed in a relatively close place where time adjustment is not necessary.

In step 305, the impeller 4 is rotated by a predetermined amount to release the contact resistance force, and at the same time, the paper is moved along the bottom plate 10 of the integrated space 6 to be integrated in the supporting plate 9 of the integrated space 6. However, at the first execution of step 305, since there is no paper, accumulation is not performed, and the impeller 4 is rotated by a predetermined amount to prepare for subsequent entry of paper, so that the braking elastic vanes 4a, 4b or 4c stops in the rotational phase superimposed with the integration guide 5.

In this way, in the front end detection of the banknote, the next sheet enters the sensor 3, whereby the control to accumulate the stationary sheet of paper is performed. Although the rotation amount of the impeller 4 is not limited, In the structure of this embodiment, it is preferable to control by 1/3 rotation (120 degree) for speed up. As the driving means of the impeller 4, it is preferable to use a pulse motor for high speed positioning or low cost. After rotation of the impeller 4, it returns to step 301 and confirms completion | finish of conveyance of paper.

In step 306, the impeller 4 is rotated to accumulate the paper stopped at the end. After that, the stop processing of the drive roller 1 is performed, and the integration operation ends.

FIG. 17 is a conceptual view illustrating a case where the small paper 20a is largely shifted in the axial direction and conveyed in a state where there is no impeller between the driven rollers 2. In this case, one of the paper side ends is separated from the impeller 4 next to the driven roller 2. Since there is no impeller between the driven rollers 2, the paper 20a cannot be stopped due to lack of contact resistance applied to the paper 20a, that is, conveyance resistance, or even if it is possible, the balance of the conveyance resistance collapses and stops. This is because the posture of the poem is inclined, and the integration becomes unstable. In this case, in order to integrate stably, it is preferable that there are a plurality of sets of drive rollers and driven rollers in the axial direction, and a set of impellers and integration guides are arranged symmetrically in the center thereof. In this way, the paper 20a can also be accumulated without any problems when the paper 20a is slightly inclined and conveyed.

As mentioned above, what has been described according to the embodiment is a normal integration operation, but it is possible and effective to perform the control described below according to the conveyance state and the accumulation state of paper. Firstly, the impeller 4 is continuously rotated until the paper 20a is conveyed to a predetermined position in the conveying path to sufficiently secure the entry space, and the impeller 4 is predetermined when the paper 20a passes the predetermined position. Stop at the rotating phase of. Secondly, the impeller 4 is intermittently driven at predetermined intervals until the paper 20a is conveyed to a predetermined position in the conveying path, thereby sufficiently securing the entry space, and the impeller 4 when the paper 20a passes the predetermined position. ) Is stopped at a predetermined rotational phase. Third, as described in the embodiment, normally, the impeller 4 is intermittently driven. However, when the paper 20a is conveyed at a predetermined interval or less, the impeller 4 is continuously rotated to perform the integration operation.

According to this embodiment, the paper is stopped by the contact resistance of the blade of the impeller and the overlapping portion of the integration guide, and then the paper is moved by rotating the impeller, so that the rear end of the paper can be arranged in order to accumulate the paper having different dimensions. And significantly improve the performance of the integrated operation. In addition, since the impeller is intermittently driven, the life of the blade can be extended and noise can be reduced at the same time as compared with the impeller of the continuous rotation system.

According to the present invention, it is possible to provide a paper stacking device capable of handling paper of various dimensions with a simple configuration by removing defects of the conventional stopper method.
