DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet handling apparatus for handling sheets, such as an automatic cash handling machine, and more particularly to stacking sequentially supplied sheets and separating them one by one as needed. The present invention relates to a sheet handling apparatus having a feeding mechanism for feeding.

[0002]

2. Description of the Related Art Conventionally, various proposals have been made in a paper sheet handling apparatus in order to satisfactorily separate and feed out the paper sheets. For example, in an apparatus described in Japanese Utility Model Publication No. 2-6013, a feeding roller having a part of the circumference made of an elastic body and a facing roller facing the feeding roller and not rotating in the feeding direction. A roller, and an auxiliary feed roller having the same diameter as the feed roller and having a part of the circumference made of an elastic material, wherein the position of the elastic material of the auxiliary feed roller is higher than the position of the elastic material of the feed roller. Are arranged according to the traveling direction. With this configuration, the sheet is first sent by the auxiliary feeding roller, and after the leading end of the sheet is stopped by the opposing roller, the sheet is sent by the feeding roller. Therefore, the skew is corrected when the leading end of the paper sheet stops at the opposing roller, and thereafter, the paper sheet aligned in the forward direction is sent out by the feeding roller.
Stable separation and feeding without skew can be performed. Further, for example, in a recirculating cash automatic teller machine having a storage unit for stacking and storing banknotes conveyed one by one and a payout unit for feeding banknotes one by one from the banknotes in the storage unit, as shown in FIG. Banknote 2 containing a pickup roller 3 rotating at the same speed and in the same direction as feed roller 2 rotated by a paper feed motor (not shown)
1 is fed and fed between the feed roller 2 and the gate roller 4. The separation guide 1 causes the bill 21 to rotate between the rotating feed roller 2 and the non-rotating gate roller 4.
Are fed and separated one by one, and are pinched by a pinch roller (not shown) that rotates following the feed roller 2 and fed by the feed roller 2 and sent out to the conveyance path. Reference numeral 7 denotes a feed roller shaft, and 9 denotes a gate roller shaft. In such a device, as shown in FIG. 3 (a), when trying to feed out a banknote 21 with four folded sides in the short direction, the fold hits the separation guide 1 and cannot be fed out or collapsed. Sometimes. Alternatively, when the bill 21 is curled in the short direction, as shown in FIG.
Of both ends 21b collide with the separation guide 1 and cannot be extended or bent. Alternatively, when the front end of the bill 21 is folded downward, as shown in FIG. 3C, the rubber portion of the gate roller 4 is in the illustrated state where the front end of the bill 21 is immediately before the sandwiching point between the feed roller 2 and the gate roller 4. In such a case, it is difficult to enter the pinching point, and there may be a problem that the tip is damaged or turned up. In FIG. 3, (a) is a perspective view showing a separated state of a banknote folded in four in the short direction, (b) is a perspective view showing a separated state of a banknote curled in the short direction, and (c). FIG. 4 is a side view showing a separated state of a bill with a broken tip. Reference numeral 3 denotes a pickup roller.

[0003]

In the above-mentioned prior art, the leading end of the fed paper sheet is rotated with the feed roller rotating along a point slightly outside the outer diameter of the gate roller which does not rotate from the storage box. Although there is a proposal or suggestion of a separation guide that guides near a pinching point with a gate roller that is not used, a separation guide having a different cross-sectional shape in the axial direction is not described. Further, as shown in FIGS. 2 and 3, paper sheets folded in four in the short direction, paper sheets curled in the short direction, or paper sheets with the tip bent downward, etc. However, there is a problem that good separation and feeding are difficult. SUMMARY OF THE INVENTION An object of the present invention is to solve such a problem and to provide a sheet handling apparatus having a stacking / feeding mechanism capable of always separating and feeding a good sheet regardless of the state of the sheet to be separated. Is to provide.

[0004]

In order to achieve the above object, a paper sheet handling apparatus according to the present invention comprises: a storage section (12, 13 or the like in FIG. 4) for storing a plurality of paper sheets; A feed roller (2 in FIG. 1) for feeding out paper sheets, a gate roller (4 in FIG. 1) disposed opposite to the feed roller and not rotating, and paper sheets fixed to the shaft of the gate roller and fed out And a separation guide (1 in FIG. 1) for guiding the feed roller and the gate roller to a sandwiching position (a position where the feed roller 2 and the gate roller 4 overlap).
The separation guide has a guide surface that is disposed lower than the outer periphery of the gate roller in the vicinity of the nipping position and exposes a part of the gate roller at the nipping position (that is, a guide surface that is disposed with a small width only on both sides of the gate roller (see FIG. 1a) and a first surface having a hole (1b in FIG. 1) having a hole for exposing the gate roller only at the nipping position so that the leading end of the sheet does not contact the gate roller except at the nipping position. A guide means and a guide surface (that is, a gate) which is arranged higher than the first guide means at a portion which does not face the feed roller near the holding position and which is located closer to the shaft end than the gate roller and rearward from the guide surface; A guide surface (1 in FIG. 1) for guiding along a point slightly outside the outer diameter of the roller.
d)), and a guide surface that is disposed lower than the first guide device and that is disposed behind the guide surface (that is, a guide that guides along a point inside the outer diameter of the gate roller). Third surface (1c in FIG. 1)
It is characterized by having guide means.

[0005]

According to the present invention, the shape of the separation guide is arranged at a very small width only on both sides of the gate roller so that, for example, when a sheet folded four times in the short direction is to be fed out, the sheet is folded. Eyes will no longer hit the separation guide,
The leading end of the paper sheet can be stably guided to the vicinity of the position where the feed roller and the gate roller are sandwiched. Further, the separation guides on both sides of the gate roller are connected in a direction perpendicular to the paper sheet, and the paper sheet is covered so that the leading end of the paper sheet does not contact the gate roller except at the sandwiching position formed by the feed roller and the gate roller. Prevents crushing and tearing of leaf tips. Further, in a portion of the separation guide that does not face the feed roller, the sheet is guided along a point slightly outside the outer diameter of the gate roller in the vicinity of the position where the feed roller and the gate roller are sandwiched, so that the sheet Lift both sides of the sheet to facilitate the separation of folded sheets.
Except for the portion having the above-mentioned shape, the separation guide for guiding along a point inside the outer diameter of the gate roller is arranged, so that even if the end of the sheet is deformed, the sheet The tip of the roller hits the shaft that fixes the gate roller,
Prevent problems that can not be extended. Therefore, regardless of the state of the paper sheets to be separated, good separation and feeding of the paper sheets can always be performed.

[0006]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 4 is a schematic view of a stacking and feeding mechanism of the automatic cash handling machine according to one embodiment of the present invention. A stacking mechanism 13 for storing and stacking the banknotes 22 and a payout mechanism 12 for separating and feeding the bills are arranged above the stacking / feeding mechanism of the present embodiment. In the feeding mechanism 12, a part of the roller is a feed roller 2 made of a member having a high friction coefficient such as rubber, and similarly, a part of the roller is a pickup roller formed of a member having a high coefficient of friction such as rubber. 3 are fixedly attached to the feed roller shaft 7 and the pickup roller shaft 8, respectively, and are driven in the same direction at the same rotational speed by a paper feed motor (not shown). The gate roller 4 having a portion that is shifted from the feed roller 2 in the axial direction and overlaps with the feed roller 2 is made of a member with a high coefficient of friction all around and is configured not to rotate in the feeding direction. . Further, behind the gate roller 4, a pinch roller 5 that is in pressure contact with the feed roller 2 is disposed. In the stacking mechanism 13, the banknotes 22 are stacked on a lift (not shown), and the position of the uppermost banknote is controlled to contact the pickup roller 3 by the vertical movement of the lift. In the separating / feeding-out operation according to the present embodiment, the pickup roller 3 is rotated by rotating the paper feed motor.
The bills 22 in contact with the feed rollers 2 are fed one by one by the frictional conveying force of the high friction coefficient member of the pickup roller 3.
And the gate roller 4. At this time, the leading end of the bill is accurately fed by the separation guide 1 to the clamping position where the feed roller 2 and the gate roller 4 overlap. Here, the leading end of the bill 22 is deformed into a waveform at a portion where the feed roller 2 and the gate roller 4 overlap, and the frictional conveying force of the rotating feed roller 2 and the frictional resistance of the gate roller 4 that does not rotate in the feeding direction. And is pinched by the pinch roller 5 and the feed roller 2 that rotate following the feed roller 2,
It is fed out to the transport path 15.

Next, the shape of the separation guide 1 of this embodiment will be described in detail with reference to FIGS. FIGS. 1A and 1B are views showing a part of a feeding mechanism according to an embodiment of the present invention, wherein FIG. 1A is a front sectional view and FIG. 1B is a perspective view. FIG. 5 is a cross-sectional view of the separation guide according to one embodiment of the present invention. FIG. 5A is a cross-sectional view taken along line AA of FIG. 1A, and FIG. ) BB section, (CC)
1A shows a CC section of FIG. 1A, and FIG. 1D shows a DD section of FIG. 1A. As shown in FIG. 1, the separation guide 1 is fixed to the gate roller shaft 9 and is symmetrical about the center line in the front view. Further, it has each cross-sectional shape shown in FIG. As shown in the AA cross-sectional view, the area (about 2 mm in width) on both sides (center side) of the gate roller 4 is a circular arc and a straight line along the outer periphery of the gate roller 4, and holds the feed roller 2 and the gate roller 4. It is composed of the guide surface 1a up to near the position. The height of the portion having the guide surface 1a is set lower than that of the gate roller 4. Further, as shown in the BB sectional view, the area along the outer periphery of the gate roller 4 has the same arc as the guide surface 1a shown in the AA sectional view, and the guide surface with a thin wall pressure is formed on the outer periphery of the gate roller. 1b. The height of the portion having the guide surface 1b is the same as that of the portion having the guide surface 1a.
Lower than the gate roller 4. Therefore, the separated bills are
It does not touch the gate roller 4 to the holding position, and therefore, for example, protects a banknote folded in the short direction from the high frictional force of the gate roller 4 and reliably feeds out the bill without generating a jam. On the other hand, as shown in the CC sectional view, the area near the center line in FIG. 1A and the area outside the feed roller 2 are inside the outer circumference of the gate roller 4 and outside the gate roller shaft 9. It is constituted by a guide surface 1c extending in the vicinity of the nipping position of the feed roller 2 and the gate roller 4 by a circular arc and a straight line along the arc. That is, the portion having the guide surface 1c is at a lower position than the portion having the guide surfaces 1a and 1b. Further, the front surface of the portion having the guide surface 1c is disposed so as to be behind the portion having the guide surfaces 1a and 1b. For this reason, for example, even if the both ends are curled downward, the both end portions can be reliably guided. Further, as shown in the DD sectional view, the area slightly outside the feed roller 2 is a gate roller 4.
Along a point outside the gate roller shaft 9 and outside the outer periphery of the gate roller 4 near the pinch position between the feed roller 2 and the gate roller 4 to a point slightly outside the outer periphery of the gate roller 4.
It is composed of an arc and a straight guide surface 1d. That is, the portion having the guide surface 1d is located higher than the portion having the guide surfaces 1a and 1b. Further, the front surface of the portion having the guide surface 1d is disposed so as to be behind the portion having the guide surfaces 1a and 1b, and is on the same plane as the portion having the guide surface 1c. For this reason, for example, even a bill with a broken tip (even with a tip lower than the gate roller shaft 9) can be reliably guided to the clamping position without causing a jam.

Next, a separation state of folded banknotes by the separation guide shape of the present embodiment will be described with reference to FIGS. In this embodiment, as shown in FIG. 1B, in the case of a new bill or a non-foldable bill 22, the leading end of the bill 22 is in contact with the guide surface 1 a of the separation guide 1 while the feed roller 2 is fed by the pickup roller 3. Is separated between the feed roller 2 that rotates and the gate roller 4 that does not rotate.
Then, the sheet is nipped by the feed roller 2 and fed out to the transport path 15. The tip of the bill 22 sent out between the feed roller 2 and the gate roller 4 is connected to the guide surface 1 of the separation guide 1.
The paper is fed between the pinch roller 5 behind the gate roller 4 and the feed roller 2 along a and 1b. On the other hand, as shown in FIG. 6, in the case of a folded bill such as the bill 23 folded in four in the short direction, the folded portion 23 a of the bill is formed on the guide surfaces 1 a and 1 b of the separation guide 1. Feed roller 2 in contact with the smooth curved surface and along the curved surface
And between the gate roller 4 and the gate roller 4 (nipping position), the bill is easily fed. As shown in FIG. 7, in the case of the short curled curled banknote 24 curled in the short direction, the end face 24a of the banknote comes into contact with the guide surface 1c lower than both ends of the separation guide 1 and is lifted. 24 becomes easy to unwind. At this time, since the front surface of the guide surface 1c is behind the guide surfaces 1a and 1b, the central portion of the bill is reliably sent to the clamping position without being lifted. Further, as shown in FIG. 8, when the tip of the bill 25 is bent downward, the tip 25a of the bill 25
The guide surface 1d, which is slightly smaller than the gate roller 4 of the separation guide 1, raises the paper money 25 without stopping the banknote 25. At this time, the front surfaces of the guide surfaces 1c are the guide surfaces 1a, 1b.
Since it is further rearward, the central portion of the bill 25 is reliably sent to the holding position without being lifted.

According to this embodiment, the separation guide 1 is provided with three types of shapes (the shapes of the guide surfaces 1a and 1b, the shape of the guide surface 1c, and the shape of the guide surface 1d), so that the folded portion of the bill can be folded. Since the end face of the curled banknote does not interfere with the separation guide 1 or the gate roller 4, it is possible to flexibly cope with a banknote having a large deformation amount, thereby suppressing the occurrence of jam and performing a good separation / delivery operation. In the present embodiment, the feed roller 2 and the gate roller 4 are separate feeding mechanisms in which the feed roller 2 and the gate roller 4 are displaced in the axial direction and overlap, but the feed roller and the gate roller are pressed against each other in the axial direction with a predetermined pressure. The same separation guide shape can be applied to the separation and feeding mechanism described above.

[0010]

According to the present invention, when the paper sheets stored in the storage section are fed by the conveying force due to the rotation of the feed roller and the pickup roller and the resistance force of the gate roller, the paper sheets having a tendency to bend in the separation guide. The folds of the paper do not interfere with each other, and the leading edge of the paper does not reach the feed roller and the gate roller, and does not stay.Therefore, regardless of the state of the paper, good separation and feeding can always be performed. is there.
