Description

  The present invention relates to a stacking technique in a paper sheet stacking apparatus for stacking media such as cash.

  FIG. 11 is a side view showing a main configuration of a conventional paper sheet stacking apparatus, and FIG. 12 is a front view thereof. As shown in the figure, the conventional paper sheet stacking apparatus is a banknote that is stacked while monitoring the position of the banknote by the feed roller 1 that functions as a feed means and functions as a means for feeding out the banknote 14 as appropriate. 14, a stage 4 that moves up and down, an impeller 5 that strikes and drops the rear end of the banknote 14 during stacking, a bill stopper 6 that stops the banknote 14 by colliding the front end, and a front guide that functions as a stacking guide 8f, a reverse guide 8r and a side guide 8s, and a travel sensor 12 for detecting the position of the banknote 14 traveling on the transport path 15 are provided.

  Moreover, although it is not an indispensable structure as a paper sheet stacking apparatus, the reverse roller 2 for preventing heavy running when the banknote 14 is fed out, the picker roller 3 that functions as a feeding roller, and the picker roller 3 are moved up and down. A picker arm 9 is provided.

  In addition, the banknote intake port comprised by the feed roller 1 and the reverse roller 2 is hereafter called a "gate part" for convenience.

  With the above configuration, when the conventional paper sheet stacking apparatus detects the banknotes transported from the transport path 15 by the travel sensor 12, each part of the feed roller 1 and the like is controlled to transfer the banknotes from the gate section to the stage 4. It discharges | emits to the accumulation area formed by the upper front guide 8f, the reverse guide 8r, and the side guide 8s above, and strikes a banknote rear end with the impeller 5, and accumulates sequentially (for example, refer patent document 1).

And when paying out the banknote 14, the stage 4 is raised, the banknote 14 is pinched | interposed between picker rollers 3, an appropriate feed force is generated, and a banknote is let out from a gate part.

  However, generally, the banknote 14 is thicker in the four corner directions as shown in FIG. 13, and when stacked, the banknote 14 is thicker in the four corner directions and lower in the center as shown in FIG. 14.

  As a result, as shown in FIG. 15, the banknotes 14 cannot be collected flat. For this reason, for example, if the stage 4 is raised when the banknote 14 is fed out, the banknote 14 contacts the picker arm 9 holding the picker roller 3 before contacting the picker roller 3, and the banknote 14 is picked up by the picker roller. 3 and the stage 4, the predetermined feed force cannot be generated, and the problem that the banknote 14 cannot be fed out occurs.

  Also, as shown in FIG. 16, the banknotes 14 to be stacked tend to be accumulated in a biased direction in the left-right direction in the longitudinal direction of the banknotes, so a gap (right corner in the figure) is formed and a convex state is formed. When the wallet banknotes 14x that were made were taken in, they entered into the gap and accumulated, and could not be accumulated in a uniform state. And the problem that this cannot be paid out occurs.

The present invention employs the following configuration in order to solve the above-described problems. That is, in the paper sheet stacking apparatus that discharges the medium to the stacking area and guides and stacks by the side guides provided on the left and right when viewed from the discharge direction , the width impeller is provided in the vicinity of the side guide and the predetermined stacking is performed. pull pulling the rotated medium position the paper side impeller for each number of media in the side guide of the, and the medium so that to integrated shifted in the opposite direction for each of the predetermined number.

According to the paper sheet stacking apparatus of the present invention, a beveled impeller is provided in the vicinity of the side guide, and the beveled impeller is rotated for each predetermined number of sheets to be stacked and the end of the medium is pulled toward the side guide. asked, since the medium was so that to integrated shifted in the opposite direction for each of the predetermined number, it is possible to flatten integrated media. In addition, since the gap in which the accumulation medium is biased in one direction can be eliminated, the medium can be stably accumulated without entering the gap.

  Embodiments of the present invention will be described below with reference to the drawings. In the following description, for convenience, the medium to be handled will be described as a banknote. However, if it is a paper sheet-like medium, it can be handled in the same manner even if it is not a banknote but a bond or a ticket. In addition, for convenience of explanation of the operation, the description will be made assuming that the picker roller etc. for feeding the accumulated banknotes is provided. However, even in an apparatus having no configuration for feeding these, the operation and effect of the present invention are the same. It is.

  The paper sheet stacking apparatus according to the first embodiment is provided with a width impeller provided with a blade part in the vicinity of a side guide for stacking banknotes, and rotates the width impeller every predetermined number of times. The part was pulled to the side guide side and accumulated.

As shown in the drawing, the paper sheet stacking apparatus of the first embodiment includes a feed roller 1, a reverse roller 2, a picker roller 3, a stage 4, an impeller 5, a bill stopper 6, a front guide 8f, a reverse guide 8r, The side guide 8s (hereinafter, the guides such as the front guide 8f are collectively referred to as “guide 8”), the picker arm 9, the drive belt 10, the picker shaft 11, the travel sensor 12, the upper surface sensor 13, the bill 14, the transport path 15, and the like. The parts are arranged.

  In the paper sheet stacking apparatus according to the first embodiment, the spread impeller 16 is disposed below the stacking area covered with the guide 8 and the stage 4 at a position in contact with both longitudinal ends of the stacked banknotes 14 when rotated. is doing.

  As shown in FIG. 2, the width impeller 16 has a structure in which a radial blade portion made of a resilient member is provided in part. The marginal impeller 16 is connected to a power transmission system (not shown), and when the banknotes are stacked, the marginal impeller 16R is rotated counterclockwise (CCW direction in the figure) on the right side in the figure. Rotating impeller 16L is rotated clockwise (CW direction in the figure), and when it is not a stacking operation such as a bill feeding operation, the rotation is stopped and the blade portion does not enter the stacking area covered with the guide 8. Thus, only a part is provided with a blade portion.

  When the banknote 14 is released from the gate portion, the squeeze impeller 16R rotates to rotate once until the next banknote is released, and when the next banknote 14 is released, the squeeze impeller 16L rotates. The beveled impeller 16L and the beveled impeller 16R are alternately rotated so as to rotate once until the next bill is released.

  When the marginal impeller 16 does not rotate, the marginal impeller 16L and the marginal impeller 16R are stopped at a position where they can be prevented from entering the accumulation area from the guide 8. Then, the squeeze impeller 16 is deformed when it strikes the banknote 14 so that a force for attracting the accumulated banknote 14 is stably generated when it rotates as shown in a squeeze impeller 16L of FIG. 5 described later. It has become.

  The feed roller 1 and the reverse roller 2 are arranged with their circumferential surfaces slightly overlapping each other, functioning as a banknote discharge port when stacking banknotes 14, and banknote taking-in port when separating banknotes. Function as. The feed roller 1 can be rotated in both clockwise and counterclockwise directions as indicated by an arrow W in FIG. 1 by a power transmission system (not shown), and the reverse roller 2 receives two or more bills when separating the bills. In order not to let out at the same time, it can be rotated only counterclockwise (CCW direction) as shown by an arrow in FIG. 1 by a power transmission system (not shown).

  The picker roller 3 has a high friction member attached to a part of its peripheral surface as shown by a hatched portion, and is disposed so as to face the stage 4 on the banknote accumulation space side when viewed from the gate portion. 2 is held by the picker shaft 11 shown in FIG. 2 and pivots up and down with the feed roller 1 as a fulcrum, and a rotational driving force is transmitted from the feed roller 1 by the drive belt 10 to rotate in synchronization with the feed roller 1. Yes.

  The stage 4 can be moved in the vertical direction by a power transmission system (not shown), and is always monitored by the upper surface sensor 12 during the stacking operation to change the position so as to secure a certain stacking area and separate the bills 14. When performing the above, the bill 14 is sandwiched between the picker roller 3 and an appropriate feed force is generated.

  The impeller 5 is a resilient member and has a structure with blades radially as shown in FIGS. 1 and 2, like the marginal impeller 16, and a plurality of rows are arranged beside the reverse roller 2. It is. When stacking, a power transmission system (not shown) rotates clockwise in the figure at a position substantially coaxial with the rotating shaft of the reverse roller 2, and when separating the bills 14, an impeller is attached to the gate portion by a retraction mechanism (not shown). Retreat to a position where the 5 blades do not overlap.

  The bill stoppers 6 are arranged in a plurality of rows at the position of the front guide 8f facing the gate portion, and are arranged so that the tips of the discharged bills 14 collide with the bill stopper 6 at the time of stacking. A spring (not shown) is connected to the bill stopper 6 so that the kinetic energy of the bill 14 can be absorbed when the tip of the released bill 14 collides with the bill stopper 6.

  The reverse guide 8r is disposed so as to cover the reverse roller 2, and the reverse roller 2 protrudes from a hole (not shown). Further, the side guide 8s is arranged facing both sides in the banknote longitudinal direction, and the front guide 8f and the reverse guide 8r are arranged facing each other to form a stacking space. The stacking space is slightly longer than the banknote 14. .

(Operation)
With the above configuration, the paper sheet stacking apparatus according to the first exemplary embodiment operates as follows. This operation will be described with reference to the operation explanatory diagrams of FIGS.

  First, the operation of banknotes during stacking will be described. As shown in FIG. 3, banknotes 14 s that have been guided by the transport path 15 from the direction of arrow A in the drawing and discharged are discharged from the gate portion to the accumulation area on the stage 4. At this time, in order to prevent the leading edge of the released banknote 14s from sagging in the direction of the stage 4, it is preferable that the banknote cross section be discharged in a corrugated manner when viewed from the running direction.

  And the discharge | release banknote 14s collides with the bill stopper 6, and the kinetic energy of the banknote 14s is absorbed with a spring.

  Then, the bill 14s colliding with the bill stopper 6 is further fed, and the bill 14s having the kinetic energy absorbed by the bill stopper 6 as shown in FIG. The end is hit by the impeller 5 and pressed onto the stage 4.

  And as shown in FIG. 5, the banknote edge part of the longitudinal direction of a banknote is pulled alternately for every banknote by the width impeller 16 in the left-right direction in the figure. That is, the longitudinal end of the banknote 14 in the rotation trajectory of the squeeze impeller 16 is pressed onto the stage 4 by the rotation of the squeeze impeller 16L in the CW direction or the rotation of the squeeze impeller 16R in the CCW direction. And pulled toward the side guide 8s.

  And the conveyance sensor 12 detects conveyance of a banknote, and whenever the banknote 14 is conveyed, the banknote 14 is turned into a banknote longitudinal direction for every sheet by rotating the left and right width impellers 16R and 16L alternately. They are drawn alternately left and right, and are stacked one by one. By stacking one sheet at a time in this way, the thick portion of the banknote 14 described with reference to FIGS. 13 and 14 can be dispersed, so that the top surface of the banknote can be flattened. The gap generated in the longitudinal direction described in FIG. 16 can be eliminated.

  As a result, since the upper surface of the stacked banknotes becomes flat, the stage 4 is moved upward, the picker roller 3 and the banknote 14 are brought into contact with each other, the banknote 14 is sandwiched between the picker roller 3 and the stage 4, and an appropriate feeding force is applied. The bills 14 can be fed out stably.

  Moreover, since the gap | interval which generate | occur | produces in the longitudinal direction of the integrated banknote can be eliminated, even when the wallet banknote 14x etc. which became convex shape are integrated | stacked, as shown in FIG. And can be stably integrated. As a result, it is possible to solve the problem that the stacked banknotes cannot be paid out.

  Of course, instead of shifting the banknotes to the left and right for each sheet as described above, it is possible to shift the banknotes to the left and right for every two sheets or more. Further, instead of providing the width impellers 16L and 16R at both ends of the bill in the longitudinal direction, as shown in FIG. 7, the bills are biased in a certain direction and accumulated so that the bill 14 does not approach. It is also possible to provide the impeller wheel 16x and rotate the width impeller wheel 16x for each predetermined number.

  For example, as shown in FIG. 7, if the stage 4 is arranged slightly diagonally in the upper right direction, the banknotes 14 are placed on the left side, and the width impeller 16x is rotated every other sheet, the same figure. As shown in FIG. 5, the banknotes 14 can be stacked while being shifted to the left and right.

  Although not shown, the stage 4 is not placed obliquely, but the conveyance path or the feed roller 1 is tilted in a certain direction in the banknote longitudinal direction so that the banknotes 14 are stacked in any direction of the banknote longitudinal direction. The banknotes 1 are arranged so as to be biased and accumulated in a certain direction by placing a conveyance guide (not shown) in the conveyance path 15, and the width impeller 16x is located in the vicinity of the side guide 8s that does not approach. May be arranged

  Further, in the above description, the marginal impeller 16 has been described as being fixedly disposed below the accumulation area covered with the guide 8 and the stage 4, but the stage 4 is connected to both ends, You may make it move with a vertical motion.

  In the above description, the blade portion is provided in part and the rotation of the width impeller 16 is stopped at a position where the blade portion does not enter the accumulation area except for the accumulation operation. Although it becomes complicated and expensive, it is possible to provide a mechanism for retracting to a position that does not interfere with the accumulated banknotes 14 except for the accumulation operation, provided with all the blade portions.

(Effect of Example 1)
As described above, according to the paper sheet stacking apparatus of the first embodiment, a marginal impeller with a part of a blade provided in the vicinity of a side guide for stacking banknotes is provided for each predetermined number of sheets. Since the impeller is rotated to draw the bill end toward the guide side, the bill can be accumulated flat.

  Moreover, since the gap in the longitudinal direction of the stacked banknotes can be eliminated, banknotes can be stably stacked without entering the gap.

  The paper sheet stacking apparatus of Example 2 has a configuration in which a bladed portion spreads when the beveled impeller is placed in a spiral shape and rotated.

(Configuration and operation)
The paper sheet stacking apparatus according to the second embodiment is provided with a spiral squeezed impeller 17 instead of the swash impeller 16. Other configurations are the same as the configurations of the first embodiment, and detailed description thereof is omitted for the sake of brevity.

  FIG. 8 is a diagram illustrating the configuration of the width impeller 17 (17L, 17R) of the paper sheet stacking apparatus according to the second embodiment. As shown in the figure, the beveled impeller 17 has a spiral shape so that the blade portions are gathered small when not rotating.

  That is, when the marginal impeller 17 is not rotating, the banknote stack is formed by the guide 8 by automatically closing the blade portion like the marginal impeller 17R on the right side of FIG. When retracted out of the area and rotated, the blade portion spreads out by the centrifugal force and abuts against the banknote 14 as shown in FIG.

  With the above configuration, when the banknote 14 is not attracted, the rotation impeller 17 is out of the banknote accumulation area just by stopping the rotation, and when the banknote 14 is attracted, it rotates and spreads. You can get in touch. And the banknote 14 can be accumulated | stacked flat similarly to Example 1 by rotating the width impeller 17L, 17R alternately for every predetermined number of sheets.

(Effect of Example 2)
As described above, according to the paper sheet stacking apparatus of the second embodiment, the squeezed impeller is placed in a spiral shape, and the blade portion expands when rotated. Therefore, when the banknote is not drawn, the rotation is stopped. By simply doing this, the beveled impeller is outside the banknote accumulation area, and when drawing the banknote, it can be rotated to spread and draw in contact with the banknote, and the beveled impeller arranged near the left and right side guides rotate alternately By doing so, it is possible to stack the bills flatly without generating a gap.

<< Other modifications >>
In the description of the above embodiment, an example in which a squeezed impeller is provided in the longitudinal direction of the banknotes and alternately pulled is shown. However, as shown in FIG. You may make it pull alternately by the F direction. Also in this case, as shown in FIG. 7, the marginal impellers 16 and 17 may be provided around the side guide opposite to the direction in which the banknotes 14 are biased and accumulated.

  Further, in the above description of the embodiment, as shown in FIG. 1, it has been described that one squeeze impeller 16 having a predetermined width is provided, but it may be wider or narrower, or a plurality thereof. You may do it.

  As described above, the present invention can be widely used in a paper sheet stacking apparatus that stacks media such as cash.
