Description

MEDIUM CONVEYING DEVICE AND PAPER MONEY HANDLING APPARATUS}

TECHNICAL FIELD This invention relates to the medium conveying apparatus which conveys a medium, for example with a drive roller and a pinch roller, and relates to the banknote handling apparatus provided with this medium conveying apparatus and handling a banknote.

Conventionally, as a mechanism which conveys a medium in media conveying apparatuses, such as a banknote handling apparatus, there exists a thing which conveys by sandwiching a medium between the drive roller which is rotationally driven, and the pinch roller which follows. The pinch roller of this mechanism is comprised so that a movement in the direction which approaches and falls with a drive roller is pressurized by the drive roller.

In recent years, with the spread of ATMs, medium carriers mounted on ATMs and the like are increasingly required to be smaller and more reliable.

In order to realize high reliability, it is necessary to prevent the medium from buckling and not damage the medium. To this end, it is necessary to carry it smoothly without giving resistance to a medium as much as possible. In order not to give resistance to a medium, it is necessary to reduce the collision angle at the time of the conveyance direction front end of a medium colliding with a pinch roller.

In addition, in order to realize miniaturization, it is necessary to make the pinch roller into a roller as small as possible.

Japanese Patent Application Laid-Open No. 2002-211784

However, the above-mentioned high reliability and miniaturization are opposite tasks, and it was difficult to be compatible.

In detail, the collision angle when the tip of a conveyance direction of a medium collides with a pinch roller is determined by the diameter of a pinch roller and the amount of protrusion which the pinch roller protrudes from a conveyance guide.

The smaller the diameter of the pinch roller for miniaturization, the greater the variation in the collision angle when the position of the pinch roller relative to the conveyance guide is shifted. And when a pinch roller protrudes excessively from a conveyance guide, the resistance given to a medium becomes large.

In addition, when the diameter of the pinch roller is small, the amount of protrusion is reduced so that the collision angle becomes small, and the amount of protrusion cannot be sufficiently secured. In this case, when the thick medium has intruded, the pinch roller pressed against the driving roller retracts to the height of the conveying guide, and the possibility of not being able to secure the conveying force increases.

For this reason, strict precision is required for the position of the pinch roller with respect to a conveyance guide.

However, since the pinch roller position is determined in contact with the opposing driving roller, it depends on the position of the driving roller. For this reason, it is difficult to ensure the positional accuracy of the pinch roller with respect to a conveyance guide, and there existed a problem that both high reliability of a medium conveying apparatus and size reduction were difficult.

SUMMARY OF THE INVENTION In view of the above-described problems, an object of the present invention is to provide a medium conveying apparatus and a bill handling apparatus that achieve both miniaturization and realization of high reliability that does not cause buckling or scratching of a medium during conveyance.

The present invention provides a driving body that obtains a driving force by rotation, a driven roller that is pressed toward the driving body and driven to the driving body, and the driven roller can move in a direction protruding and evacuating toward the driving body. And a press body for pressing the driven roller supported by the support toward the driving body, the medium being sandwiched between the driving body and the driven roller provided in a conveying path for conveying the medium. It is a medium conveying apparatus which conveys in the said conveyance path, Comprising: It is a medium conveying apparatus provided with the conveyance guide body which moves to the direction which protrudes and retracts with the said driven roller.

According to the present invention, it is possible to provide a medium conveying apparatus and a bill handling apparatus that are both attained in miniaturization and in achieving high reliability in not causing buckling or scratching of the medium during conveyance.

FIG. 4 is an enlarged view showing a pinch roller support guide 40 portion as a conveyance guide member of the banknote conveying apparatus 20, and FIG. 5 is a description by a cross-sectional view of the pinch roller support guide 40 terminated and viewed in a conveying direction. It is also.

As shown in FIG. 3, the conveyance path 5 is a banknote conveyance space 26 formed by facing the conveyance guides 25 and 27 at fixed intervals (for example, 4 mm. It may be about 5 mm to 5 mm).

On the conveyance guide 27 side, the pinch roller 31 as a driven roller is provided so that it may protrude inward from the outer side (downward) of the banknote conveyance space 26, and the conveyance guide 25 side of the banknote conveyance space 26 The drive roller 21 as a drive body is provided so that it may protrude inward from an outer side (above illustration). The driving roller 21 and the pinch roller 31 are disposed to face each other, and are configured to be in contact with each other in the bill conveyance space 26. Moreover, the drive roller 21 is comprised by the magnitude | size required in order to ensure a conveyance speed, and the pinch roller 31 is comprised smaller than the drive roller 21. As shown in FIG.

The roller shaft 23 is provided in the inner ring of the drive roller 21, and is rotatably supported by the support part (not shown) by the side of the conveyance guide 25 at a fixed position. The drive roller 21 receives a rotational driving force from a motor (not shown) and rotates in the conveying direction about the shaft center 22 of the roller shaft 23.

Both sides of the pinch roller 31 are supported by the pinch roller support guide 40, and both sides of the pinch roller 31 are supported by a fixing frame 53 serving as a support of the fixing table 50. This pinch roller 31 is in contact with the drive roller 21, and is driven to rotate in accordance with the rotation of the drive roller 21.

Thereby, the conveyance banknote M as a medium is pinched | interposed by the drive roller 21 and the pinch roller 31, and it conveys in a conveyance direction. When the conveyance banknote M is sandwiched in this conveyance, the pinch roller 31 is withdrawn from the driving roller 21 as shown in FIG. 5B (conveying banknote M). Corresponding to the thickness of the layer). After conveying to the terminal of conveyance banknote M, the pinch roller 31 is in the protruding state which contacts the drive roller 21, as shown to FIG. 5 (A).

The pinch roller support guide 40 is formed symmetrically in a banknote conveyance direction as shown in FIG. 3, and is formed symmetrically in a conveyance width direction as seen from the banknote conveyance direction as shown to FIG. 5 (A). .

This pinch roller support guide 40 has a substantially rectangular plate-shaped side guide 41 at both ends (axial ends) of the pinch roller 31, and by this side guide 41. The pinch roller 31 is sandwiched between them. This pinch roller support guide 40 has a substantially U-shaped shape as shown in FIG. 5A when viewed in the conveying direction. This side guide 41 is separated from the conveyance guide 27.

The side guide 41 is formed thinner (for example, 1 mm) than the thickness of the pinch roller 31 in the axial direction. Thereby, the contact resistance with conveyance banknote M is made small. Moreover, the banknote conveyance guide surface P which protrudes from the conveyance guide 27 to the banknote conveyance space 26 in the length of the conveyance direction of the side guide 41, especially the projection state shown to FIG. 5 (A) (FIG. 3). Reference) is configured not to be too long, and is configured to be shorter than the diameter of the drive roller 21 in this embodiment.

The side guide 41 is provided with a support hole 49 (see FIG. 4) as a support part for rotatably supporting the roller shaft 33 that has passed through the inner ring of the pinch roller 31. This support hole 49 is formed so that the clearance gap with the outer periphery of the roller shaft 33 may become small, and when the position of the pinch roller 31 displaces in the up-down direction shown, also the pinch roller support guide 40 may be integrated. It is comprised so that it may displace by the same distance in the same direction.

The fixing frame 53 is provided in the fixing stand 50 so that the fixing frame 53 may stand toward the conveyance guide 27 side, and pinch roller support guide 40 is sandwiched therebetween. The left and right widths (length in the conveying direction) of the fixing frame 53 are in contact with the roller shaft 33 of the pinch rollers 31, and the upper and lower widths (lengths in the direction of the conveying path to the conveying path) are pinch rollers ( The long hole 54 longer than the diameter of the roller shaft 33 of 31 is formed. The roller shaft 33 of the pinch roller 31 is inserted through this long hole 54, and the pinch roller support guide 40 and the pinch roller 31 approach and drive the drive roller 21 by this. It is supported so that displacement is possible in the direction to make.

Moreover, the spring mounting part 51 is provided upright in the fixing stand 50. As shown in FIG. The spring mounting portion 51 is attached with a spring 52 as a pressurizing body that presses the roller shaft 33 toward the driving roller 21. This spring 52 is pushed so that the pinch roller 31 may contact the drive roller 21, and when the conveyance banknote M is clamped between the drive roller 21 and the pinch roller 31, it pinches the roller. Allowing 31 to retract by the retraction amount D (refer FIG. 5 (B)) equal to the thickness of conveyance banknote M. FIG.

That is, when the conveyance banknote M reaches | attains the contact point V (pinching part) of the drive roller 21 and the pinch roller 31 in the state which rotated the drive roller 21, the pinch roller 31 ) And the pinch roller support guide 40 bend the spring 52 and move downwards (in the direction away from the driving roller 21) by the thickness of the conveyance banknote M. In this state, the pinch roller 31 and the pinch roller support guide 40 are pressed upward by the force of the spring 52, and the pinched roller is pushed by the drive roller 21, thereby driving the drive roller 21. The conveyed banknote M is conveyed at the same speed as the outer circumferential speed of.

Moreover, the through hole 55 is provided in the fixing base 50 at the bottom of the position where the conveyance guide 27 is provided.

A restricting protrusion 47 protruding from the bottom of the pinch roller support guide 40 is inserted into the through hole 55. Accordingly, when the pinch roller support guide 40 is displaced in a direction close to and away from the drive roller 21 together with the pinch roller 31, the restricting protrusion 47 is regulated and moved in the through hole 55. Thus, the pinch roller support guide 40 functions as an inclination restricting portion so as not to incline. Therefore, the pinch roller support guide 40 does not rotate even if the pinch roller support guide 40 does not rotate along the rotating pinch roller 31 and moves in accordance with the moving pinch roller 31, and thus the conveyance guide surface of the conveyance guide 27 ( The inclination to 27a) can always be kept constant.

As shown in FIG. 4, banknote conveyance guide surface P (P1-P4) is provided in the banknote conveyance space 26 side of the side guide 41 of the pinch roller support guide 40. As shown in FIG.

The banknote conveyance guide surface P has the center part P1 located in the roller shaft 33 side rather than the contact point V (pinching part) which the pinch roller 31 contacts with the drive roller 21, and the pinch roller ( Intersection P2 before and after the conveyance direction intersecting with the outer circumference of the pinch roller 31 as viewed from the axis center 32 direction of the 31, and the outer side of the conveyance guide 27 more smoothly from this intersection P2 back and forth to the conveyance direction It has circular-shaped slope P3 descending to the roller shaft 33 side, and the front-rear end P4 used as the terminal of the slope P3.

The intersection point P2 of the circular arc of the side guide 41 and the pinch roller 31 does not exceed the height of the contact point V of the pinch roller 31 and the drive roller 21, and, if possible, the side guide ( The protrusion amount C (see FIG. 5A) of the pinch roller 31 from 41 is set to a height that decreases. In addition, this height is set to the height which can hold | maintain the conveyance banknote firmly by the drive roller 21 and the pinch roller 31, and can ensure a conveyance force.

The front-rear end P4 used as the end of the slope P3 is evacuated to a position lower than the conveyance guide surface 27a (outside of the paper conveyance space 26) so that the conveyed banknote M which has been conveyed does not collide. It is. Here, since the error by the component precision and assembly precision at the time of manufacture is absorbed, the roller shaft of the pinch roller 31 (at the edge part of the paper conveyance space 26 side) of the long hole 54 shown in FIG. Even if 33 is in contact with each other, the front and rear ends P4 are preferably configured to be in a position lower than the conveyance guide surface 27a.

In addition, the slope P3 from the intersection P2 to the front and rear ends P4 is parallel to the conveying guide surface 27a or descends downward as it goes to the front and rear ends P4 (away from the driving roller 21). It is configured so that there is no inclination or step opposite to this.

In detail, the slope P3 is in the height between the shaft center 32 of the pinch roller 31 at the contact point V of the pinch roller 31 and the drive roller 21 in the thickness direction of conveyance banknote M. As shown in FIG. It is comprised so that it may be located, and the intersection P2 side of the slope P3 is located between the conveyance guide surface 27a at the contact point V, and the outer side of the conveyance guide surface 27a (of the paper conveyance space 26). The front and rear end P4 side of the slope P3 enters and is hidden so that it may be hidden.

Thereby, the collision and the jam of the conveyance banknote M are prevented and the conveyance can be carried out smoothly.

The bill conveyance space 28 (refer FIG. 3) formed by the bill conveyance guide surface P and the conveyance guide 25 is the bill conveyance space 26 formed by the conveyance guide 25 and the conveyance guide 27. As shown in FIG. It is narrower than), and is 2 mm, for example.

By the banknote conveying apparatus 20 of the above structure, the realization of miniaturization and the high reliability which does not generate | occur | produce a buckling and a wound of a medium at the time of conveyance can be compatible.

Since the pinch roller support guide 40 moves together in the direction which protrudes and retracts toward the drive roller 21 with the pinch roller 31, the collision angle with the conveyance banknote M can always be made small. .

That is, when the conveyance banknote M collides directly with the pinch roller 31 near the intersection of the outer periphery of the pinch roller 31 and the conveyance guide surface 27a, a collision angle becomes large, for example. However, by the structure mentioned above, conveyance banknote M collides with the gentle banknote conveyance guide surface P provided in the side guide 41 of the pinch roller support guide 40 before colliding with the pinch roller 31. Then, it guides to the contact part of the pinch roller 31 and the drive roller 21. For this reason, it can implement | achieving to make collision angle (theta) (refer FIG. 4) small.

And since the banknote conveyance guide surface P of the pinch roller support guide 40 moves to the direction which protrudes and retracts with the pinch roller 31, it absorbs the deviation of the manufacturing precision of the banknote conveyance apparatus 20, Regardless of the position of the drive roller 21 or the conveyance guide 27, the collision angle (theta) of the conveyance banknote M is always made small, and the conveyance banknote M is driven by the drive roller 21 and the pinch roller ( The contact point (V) of 31) can be introduced smoothly with little resistance.

Moreover, according to the present Example which made the banknote conveyance space 26 into 4 mm, the banknote conveyance space 28 into 2 mm, and made the width | variety of the side guide 41 into 1 mm, the precision of each component differs. Even if there existed, the variation | variation in the vicinity of the contact point V of the drive roller 21 and the pinch roller 31 can be suppressed about ± 3 mm, and a banknote wound and jam can be prevented.

Further, even when the thick banknote is held by the drive roller 21 and the pinch roller 31, the pinch roller 31 moves downward by the thickness of the banknote together with the pinch roller 31. It is possible to prevent the roller 31 from retracting to the conveying guide surface 27a and failing to secure the conveying force hidden.

In addition, by forming the slopes P3 both before and after the conveyance direction of the pinch roller 31, the banknote conveyance from both directions as well as one direction can be supported.

Moreover, from the time when the pinch roller 31 protrudes to the position which contacts the drive roller 21, from the conveyance banknote M to the position where the pinch roller 31 is retracted, the banknote conveyance guide surface P Since the front and rear ends P4 of) are always located outside the bill conveyance space 26 from the conveyance guide surface 27a, the pinch roller 31 and the drive roller ( 21 can be directed toward the contact point V. That is, for example, when the pinch roller support guide 40 protrudes excessively and the front-back end P4 is located in the banknote conveyance space 26, conveyance banknote M will collide with the vertical side surface of the side guide 41, and it will jam. This causes the occurrence, but this can be prevented.

Moreover, since the pinch roller support guide 40 is not inclined by inserting the regulation protrusion 47 into the through hole 55, the angle at which the conveyed banknote M collides with the banknote conveyance guide surface P is set. It can be surely realized to always be small.

Moreover, since the side guide 41 was formed thinner than the axial thickness of the pinch roller 31, a contact resistance with conveyance banknote M can be reduced and a banknote damage and a jam can be prevented.

In particular, since the conveyance direction length of the banknote conveyance guide surface P was made into the structure which does not become too long, the banknote conveyance space can be reduced and the banknote wound and jam can be prevented. That is, as shown in FIG. 3, the banknote conveyance space 28 formed between the banknote conveyance guide surface P and the conveyance guide 25 is a banknote formed between the conveyance guide 25 and the conveyance guide 27. It becomes narrower than the conveyance space 26. And when a narrow banknote conveyance space lasts for a long time, resistance to buckled banknotes, wrinkled banknotes, etc. becomes large, and the possibility of a banknote wound and a jam increases. On the other hand, since the area | region of the narrow banknote conveyance space 28 was made as small as possible so that the area | region of the narrow banknote conveyance space 28 may be limited to the area | region near the pinch roller 31 by shortening the conveyance direction length of banknote conveyance guide surface P, It can prevent occurrence.

Thus, in the banknote conveyance path where the small difference of the frequency of a collision angle and the narrow difference of a conveyance path leads to the big obstacle such as a banknote wound and a jam, the pinch roller 31 which has a larger radius size is smaller in size. When the pinch roller support guide 40 displaces with the pinch roller 31 the bar which becomes easy to generate | occur | produce the said big obstacle further, can attain both quality assurance of a stable operation, and miniaturization. Furthermore, by following the pinch roller support guide 40 to the movement of the pinch roller 31, it is possible to ensure quality without depending on the component precision of the conveyance guides 25 and 27, the drive roller 21, or the pinch roller 31. Miniaturization can be realized.

In addition, this invention is not limited only to the structure of embodiment mentioned above, Many embodiment can be obtained.

The front and rear ends of the arc-shaped slope R3 descending to the outer side (the roller shaft 33 side) of the conveyance guide 27 and the end of the slope R3 while bending from the intersection point R2 back and forth in the conveying direction. R4). The center part R1 is formed so that it may become concave to the outer side (roller shaft 33 side) of the conveyance guide 27 in the side position of the pinch roller 31 which does not affect conveyance performance.

Even in this configuration, the same effects as in the above-described embodiment can be obtained.

In this example, the shape of the banknote conveyance guide surface T formed on the upper surface of the side guide 41c of the pinch roller support guide 40c and the thickness of the side guide 41c are different. Same as the example.

The side guide 41 of this embodiment is formed thicker than the above-mentioned embodiment. The banknote conveyance guide surface T is provided on the pinch roller 31 side of the upper surface of the side guide 41. And the inclined surface Ta which goes down to the outer side (roller shaft 33 side) of the conveyance guide 27 is provided in the opposite side to the pinch roller 31 of the upper surface.
