Description

Paper money identifying counter

Technical Field

The present invention relates to a bill identifying and counting apparatus which receives bills in a bill conveying table (hopper), identifies and counts denominations of the received bills, and calculates a total amount of the received bills or the number of bills for each denomination, and more particularly to a bill identifying and counting apparatus which: it is possible to convey banknotes having a plurality of different sizes without inclining the banknotes, and it is possible to smoothly convey banknotes having a curl (warp) or a curve.

Background

Such a banknote recognition counter is known: banknotes of mixed denominations are collectively received in a banknote transport table, the received banknotes are transported and transported one by one, the denominations and authenticity thereof are identified and counted, and the total amount of received normal banknotes or the number of banknotes per denomination is calculated and displayed (see, for example, japanese patent application laid-open No. 2003-296801).

The general configuration and operation thereof will be described with reference to fig. 1. Fig. 1 is a sectional view showing an internal structure of a general bill identifying and counting machine.

In the figure, the banknotes placed in the banknote transport unit 1 are fed to the transport path of the banknote recognition and counting machine by the transport rollers 5, and are transported by the plurality of transport rollers 6. The paper money during conveyance passes through the passage sensors 7a and 7b, and the denomination and authenticity are discriminated by the paper money discriminating sensor 8. Then, when the bill passes through the passage sensor 7c and is judged to be a normal bill by the bill identifying sensor 8, the bill is captured between the blades of the rotating impeller 9 and is collected in order in the bill receiving table section 2. On the other hand, when the bill discriminating sensor 8 determines that the bill is a counterfeit bill, the electromagnet 10 is operated, and the branch claw 11 moves to the lower side to feed the bill to the reject portion 3. Further, reference numeral 4 denotes an operation display unit which can perform various settings when performing the banknote recognition and counting process.

However, in the bill identifying and counting machine as described above, when bills (for example, euro bills) having a large difference in the longitudinal dimension due to different denominations are placed on the placing table 1a of the bill transporting section 1 as shown in fig. 2, the bills having a large longitudinal dimension (500 euro) P1 are transported into the machine without being tilted, whereas the bills having a small longitudinal dimension (5 euro) P2 may be transported while being tilted. As shown in fig. 2, when the banknote P2 approaches one of the side banknote transport units 12a and 12b arranged in bilateral symmetry (the right side banknote transport unit 12a in fig. 2), the two transport rollers 5a and 5b are arranged in bilateral symmetry in the vicinity of the center of the placement table 1a, and the banknote P2 is transported into the transport path in a state where the banknote P2 is not sufficiently abutted, that is, in a state where the left transport roller 5b is not abutted against the banknote P2, and therefore the banknote P2 is inclined. The banknotes P2 conveyed into the conveyance path at an angle in this way become a cause of a decrease in the throughput rate.

Note that some of the banknotes placed in the banknote transport section 1 include banknotes having flaws such as curling (warping) or bending (bending) caused by metal wheels (metal wheels). Such defective banknotes are also a cause of a decrease in the pass rate because they are caught at the insertion port.

Therefore, for example, japanese patent application laid-open No. 2003-276931 discloses a device capable of collecting such defective banknotes satisfactorily. In this device, a side bill conveying section is provided on a side portion of a bill collecting table, and a support side bill conveying section is rotatably provided on the side bill conveying section. The lower part of the side banknote conveying part and the lower part of the side banknote conveying part are supported to form a part similar to the straight track of the curled banknote. This prevents the curled banknotes from being fed into the side note transport when they have been straightened.

However, the device disclosed in the above-mentioned japanese patent application laid-open No. 2003-276931 is a device for collecting curled bills well in a bill collecting section, and is not a bill recognizing counter which can prevent curled bills from hooking into an insertion slot in a bill conveying section of the bill recognizing counter, which is an object of the present invention.

Further, even if a structure including the side banknote carrying section and the support side banknote carrying section is applied to the insertion port of the banknote carrying section of the banknote recognition and counting machine, the structure has a problem that the manufacturing cost is high because the number of parts is large and the apparatus is bulky.

Disclosure of Invention

The present invention has been made in view of the above problems, and an object of the present invention is to provide a bill discriminating counter capable of smoothly conveying a plurality of kinds of bills having different sizes without inclining the bills and conveying the bills having flaws such as curling (warping) and bending.

The above object of the present invention is achieved by the following means: a banknote discriminating and counting device is provided which fills a plurality of banknotes having different longitudinal dimensions in an overlapped state between side banknote transporting members arranged on a placement table in a bilaterally symmetrical positional relationship, and sequentially transports the banknotes from an insertion port into a transport path by a transport mechanism having a plurality of rollers arranged in a bilaterally symmetrical positional relationship, the plurality of rollers being arranged such that: when the banknote having the smallest longitudinal dimension among the banknotes is arranged at a position in contact with any one of the side banknote transport members while being adjusted between the side banknote transport members according to the longitudinal dimension of the banknote having the largest longitudinal dimension among the banknotes, at least a part of the roller provided at a position opposite to the side banknote transport member at the side in contact with the banknote having the smallest longitudinal dimension abuts against the banknote having the smallest longitudinal dimension.

In addition, the above object of the present invention is effectively achieved by the following means: the conveying mechanism includes: a plurality of kicking rollers which are arranged on the placing table in a bilaterally symmetrical position relationship and convey the paper money to the downstream; a plurality of bill feeding rollers disposed at a downstream side of the bill kicking roller in a bilaterally symmetrical positional relationship, the bill being fed from the bill kicking roller and being taken into the conveyance path; a plurality of reverse rollers arranged opposite to the bill feeding roller and adjusting a gap between the bill feeding roller and the bill feeding roller to be capable of passing only one bill; a plurality of auxiliary rollers arranged on the upstream side of the reverse roller opposite to the bill feeding roller for assisting the bill kicking roller in conveying the bills; and a plurality of pinch rollers arranged on the downstream side of the reverse roller so as to face the bill feeding roller, the pinch rollers taking in the bills passing through the gap between the bill feeding roller and the reverse roller into the conveyance path,

the coin kicking roller, the coin feeding roller, the counter roller, the auxiliary roller and the pinch roller are configured to: when the banknote having the smallest longitudinal dimension among the banknotes is arranged at a position in contact with any one of the side banknote transport members while being adjusted between the side banknote transport members according to the longitudinal dimension of the banknote having the largest longitudinal dimension among the banknotes, at least a part of the rollers provided at a position on the opposite side of the side banknote transport member from the position in contact with the banknote having the smallest longitudinal dimension abuts against the banknote having the smallest longitudinal dimension.

The above object of the present invention is achieved by the following means: a banknote discriminating counter in which a plurality of banknotes are stacked between side banknote transport members arranged on a placement table in a bilaterally symmetrical positional relationship, and the banknotes are sequentially transported from an insertion port into a transport path by a transport mechanism, wherein the transport mechanism includes a guide member for guiding the banknotes transported to the insertion port to an inlet of the transport path, the guide member includes a guide surface formed so that an opening area thereof gradually increases toward both ends, and the guide surface is formed such that: the opening area converges to 0 as going from the insertion port to the inlet of the conveying path.

According to the bill identifying and counting apparatus of the present invention configured as described above, even when bills are filled between the side bill conveying members arranged in bilateral symmetry and a bill having the smallest dimension in the longitudinal direction among the bills is arranged at a position in contact with any one of the side bill conveying members, the bill kicking roller, the bill feeding roller, the reverse roller, the auxiliary roller, and the pinch roller of the conveying mechanism are arranged such that: since at least a part of the rollers provided at the opposite side position of the side banknote feeding member that is in contact with the banknote having the smallest longitudinal dimension (that is, the rollers disposed on the left side when the banknote is disposed at the position in contact with the right banknote feeding member) are in contact with the banknote having the smallest longitudinal dimension, the banknote can be sequentially fed into the transport path without being tilted. This improves the passage rate of the banknotes and enables the progress of the banknote counting operation.

Further, the guide member provided in the insertion port has a guide surface formed so as to gradually increase in opening area toward both ends thereof, the guide surface being formed so as to: since the opening area converges to 0 as going from the insertion port to the entrance of the transport path, even when a banknote having a flaw such as a curl or a bend at its end is conveyed to the insertion port, the banknote can be smoothly corrected to a flat shape without interfering with the front surface portion of the guide member. This can prevent the occurrence of a decline or the like that causes a decrease in the pass rate, and can improve the banknote counting operation. Further, the guide member has a simple structure with a small number of parts and is easily processed, and therefore, can be manufactured at low cost.

Detailed Description

Embodiments of the present invention are described below with reference to the drawings.

First embodiment

Fig. 3 is a sectional view of a main part showing a transport mechanism of a bill recognizing and counting machine according to a first embodiment of the present invention. Fig. 4 is a perspective view showing an external appearance of the conveyance mechanism, and fig. 5 is a plan view showing an internal structure of the conveyance mechanism. In these figures, in the transport mechanism 20 according to the first embodiment, the side banknote transport units 32 (the right banknote transport unit 32a and the left banknote transport unit 32b) are disposed in a bilaterally symmetrical positional relationship on the placement base 31 of the banknote transport unit 30, and a plurality of banknotes P having different sizes are stacked between the side banknote transport units 32, and the stacked banknotes P are sequentially transported from the insertion port 33 into the transport path 40.

The conveying mechanism 20 has the following components: a kick roller 21 (a right roller 21a and a left roller 21b) which rotates clockwise in fig. 3 for conveying the bill P in the direction inside the machine (rightward in fig. 3); and a bill feeding roller 22 (a right roller 22a and a left roller 22b) disposed downstream (on the right side in fig. 3) of the kick roller 21 and configured to take in the bill P conveyed from the kick roller 21 into the conveyance path 40, the kick roller and the bill feeding roller being provided in a pair on the left and right. As shown in fig. 5, the kick rollers 21a and 21b and the feed rollers 22a and 22b are disposed in a bilaterally symmetrical positional relationship.

Further, a pair of reversing rollers 23 (a right roller 23a and a left roller 23b) are provided at positions facing the bill feeding rollers 22, and the gap between the reversing rollers 23 and the facing bill feeding rollers 22 is adjusted so that only one bill P can pass therethrough. Therefore, by the rotation of the bill feeding roller 22 in the clockwise direction in fig. 3, only the lowermost one of the bills P can pass between the bill feeding roller 22 and the reverse roller 23.

Further, a pair of auxiliary rollers 24 (a right roller 24a and a left roller 24b) symmetrically disposed on the left and right sides in a positional relationship facing the bill feeding roller 22 are provided on the upstream side (left side in fig. 3) of the reverse roller 23, and the auxiliary rollers 24 assist the bill P to be fed by the bill kicking roller 21.

Further, a pair of pinch rollers 25 (right roller 25a and left roller 25b) symmetrically disposed on the left and right sides in a positional relationship facing the bill feed roller 22 are provided on the downstream side (right side in fig. 3) of the reverse roller 23, and the pinch rollers 25a and 25b are brought into contact with the bill feed roller conveying portions 22a 'and 22 b' having a higher friction coefficient than the other bill feed rollers 22, whereby the bills P having passed through the gap between the bill feed roller 22 and the reverse roller 23 are reliably taken into the conveying path 40.

As shown in fig. 4, the side banknote transporting members 32a and 32b arranged on the left and right sides of the placement base 31 are slidable in the direction of the arrow X-X' in conjunction with each other, and the width L between the side banknote transporting members 32a and 32b can be arbitrarily adjusted according to the purpose of use. In the first embodiment, as shown in fig. 6, among the banknotes P (for example, euro banknotes) filled in the banknote transport section 30, the banknote P1(500 euro: 160mm × 82mm) having the largest longitudinal dimension is A1(160mm), the banknote P2(5 euro: 120mm × 62mm) having the smallest longitudinal dimension is a2(120mm), and the width L between the side banknote transport members 32a and 32b is limited so that a gap Y (5mm) is added to the longitudinal dimension A1 of the banknote P1 having the largest longitudinal dimension to become A1+ Y (160mm +5 mm).

Next, the arrangement relationship of the rollers of the conveying mechanism 20 will be described with reference to fig. 6 to 9. Here, a case where the banknote P2 having the smallest longitudinal dimension (hereinafter referred to as the smallest banknote) is disposed between the right banknote transport unit 32a and the left banknote transport unit 32b, near either of the left and right banknote transport units 32, that is, a case where one end (short side) of the smallest banknote P2 comes into contact with the right banknote transport unit 32a will be described.

Fig. 6 is a plan view for explaining the arrangement relationship of the kick rollers 21a and 21 b. As shown in the figure, the kick rollers 21a, 21b are configured such that: even in the case where the minimum banknote P2 is disposed at a position in contact with the right banknote transport unit 32a, at least a part of the left kick roller 21b, that is, at least a roller provided on the centermost side (right side) of the left kick roller 21b, abuts against the minimum banknote P2. Therefore, when the size from the right bill conveying part 32a to the left end of the rightmost roller of the left bill kicking roller 21B is B, the bill kicking rollers 21a and 21B are rotated by the rotating shaft

B≤A2……(1)

The configuration relationship of (1).

Fig. 7 is a front view for explaining the arrangement relationship between the coin feed rollers 22a and 22b and the auxiliary rollers 24a and 24 b. As shown in the figure, the auxiliary rollers 24a, 24b are configured to: even in the case where the minimum banknote P2 is disposed at the position where it contacts the right banknote transport unit 32a, the left auxiliary roller 24b abuts against the minimum banknote P2. Therefore, when the size from the right bill conveying part 32a to the outer end (left end) of the left auxiliary roller 24b is C, the auxiliary rollers 24a, 24b are rotated

C≤A2……(2)

The configuration relationship of (1). When the dimension from the outer end (right end) of the right auxiliary roller 24a to the outer end (left end) of the left auxiliary roller 24b is F, the auxiliary rollers 24a and 24b are arranged in such a manner that

F/2≤A2-L/2……(3)。

That is, if the right auxiliary roller 24a and the left auxiliary roller 24b are disposed at a reduced interval from each other, the disposition relationship of the above equation (3) can be maintained, and the minimum banknote P2 can be brought into contact with the minimum banknote P2 even when the minimum banknote P2 is disposed at an arbitrary position between the side banknote carrying members 32.

Fig. 8 is a front view for explaining the arrangement relationship between the coin-feeding rollers 22a and 22b and the reverse rollers 23a and 23 b. As shown in the figure, the counter rollers 23a, 23b are configured such that: even when the minimum banknote P2 is disposed at a position in contact with the right banknote transport unit 32a, the left reverse roller 23b abuts against the minimum banknote P2. Therefore, when the size from the right banknote transport section 32a to the outer end (left end) of the left reverse roller 23b is D, the reverse rollers 23a, 23b rotate

D≤A2……(4)

The configuration relationship of (1). When the dimension from the outer end (right end) of the right counter roller 23a to the outer end (left end) of the left counter roller 23b is G, the counter rollers 23a and 23b are arranged in such a manner that

G/2≤A2-L/2……(5)。

That is, if the right and left reversing rollers 23a and 23b are disposed at a reduced interval from each other, the disposition relationship of the above equation (5) can be maintained, and the minimum banknote P2 can be brought into contact with the minimum banknote P2 when it is disposed at any position between the side banknote carrying members 32.

FIG. 9 is a front view for explaining the arrangement relationship between the coin feed rollers 22a and 22b and the pinch rollers 25a and 25 b. As shown in the figure, pinch rollers 25a, 25b are configured: even when the minimum banknote P2 is disposed at the position where it contacts the right banknote transport unit 32a, the left pinch roller 25b contacts the minimum banknote P2. Therefore, when the size from the right banknote transport section 32a to the outer end (left end) of the left pinch roller 25b is E, the pinch rollers 25a and 25b are rotated by the rotation of the left pinch roller 25b

E≤A2……(6)

The configuration relationship of (1). When the dimension from the outer end (right end) of the right pinch roller 25a to the outer end (left end) of the left pinch roller 25b is H, the pinch rollers 25a and 25b are arranged in such a manner that

H/2≤A2-L/2……(7)。

That is, if the right pinch roller 25a and the left pinch roller 25b are disposed so that the distance therebetween is reduced, the disposition relationship of the above equation (7) can be maintained, and even if the minimum banknote P2 is disposed at any position between the side banknote feeding members 32, the minimum banknote P2 can be brought into contact therewith.

In addition, although the case where the minimum banknote P2 contacts the right banknote transport unit 32a has been described in fig. 6 to 9, the rollers of the transport mechanism 20 are arranged in a bilaterally symmetrical positional relationship, and therefore, the case where the minimum banknote P2 contacts the left banknote transport unit 32b can be described as the same as the above.

In fig. 7 to 9, the auxiliary roller 24, the counter roller 23, and the pinch roller 25 are respectively arranged as a pair on the left and right, but the present invention is not limited thereto, and a plurality of rollers may be provided on the left and right. In this case, at least the roller provided on the center side among the rollers disposed on the left and right sides is disposed so as to abut on the minimum banknote P2.

As described above, according to the bill identifying and counting apparatus of the first embodiment of the present invention, the kick roller 21, the feed roller 22, the reverse roller 23, the auxiliary roller 24, and the pinch roller 25 of the bill conveying mechanism 20 are arranged so that, even when the adjustment is made between the side bill conveying members 32a, 32b arranged in bilateral symmetry in accordance with the longitudinal dimension a1 of the bill P1 and the bill P2 having the smallest longitudinal dimension among the bills P is arranged at the position in contact with any one of the side bill conveying members 32, at least a part of each of the right rollers 21a, 22a, 23a, 24a, 25a and the left rollers 21b, 22b, 23b, 24b, 25b abuts on the bill P2. That is, the plurality of rollers provided in the banknote transport mechanism 20 are arranged so that at least a part of the rollers provided at a position opposite to the side banknote transport member 32 on the side of contact with the banknote P2 abuts against the banknote P2. Thus, even if the banknotes P filled in the banknote transport unit 30 have large differences in the longitudinal dimension, such as euro banknotes, the banknotes P can be sequentially transported into the transport path 40 without being tilted. As a result, the passing rate of the banknotes is improved, and the banknote counting operation can be improved.

Second embodiment

Next, a second embodiment of the present invention will be described with reference to fig. 10 and 11. In the present embodiment, the same members as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

Fig. 10 is a front view of a bill feeding section of a bill identifying and counting machine according to a second embodiment of the present invention, and fig. 11 is a side view of a main portion showing an internal structure thereof. As shown in fig. 11, a plurality of banknotes P are stacked on the placement base 31 of the banknote transport unit 30 between the side banknote transport units 32 (the right banknote transport unit 32a and the left banknote transport unit 32 b). The placing table 31 is provided with a kick roller 21 for sequentially conveying the filled banknotes P in the direction of the insertion port 33. A coin feeding roller 22 is provided below the insertion port 33, and a reverse roller 23, an auxiliary roller 24, and a pinch roller 25 are provided above the insertion port 33 and disposed at positions facing the coin feeding roller 22. The banknotes P filled in the banknote transport unit 30 are fed out into the transport path 40 one by one through the insertion slot 33 by the transport mechanism 20 having these rollers.

Further, a guide member 50 is provided above the insertion port 33, and the guide member 50 guides the transported bill P to the pinch roller 25 as the entrance of the transport path. As shown in fig. 10, guide surfaces 51a and 51b are formed on the guide member 50, and the guide surfaces 51a and 51b are formed so as to gradually increase in opening area 34a and 34b toward both ends. This prevents: the banknotes P' having flaws such as curling or bending at both end portions, which are included in the banknotes P filled in the banknote transport section 30, interfere with the front surface 52 of the guide member 50 when being transported to the insertion port 33.

As shown in fig. 11, the guide surface 51 is provided over the entire range from the insertion port 33 up to the pinch roller 25. The guide surfaces 51a and 51b are formed as follows: the opening areas 34a and 34b at both ends converge to 0 as they face the pinch rollers 25 as the entrance of the conveyance path. Thus, the bill P' having the above-described defect that has passed through the insertion port is corrected to a flat shape before reaching the pinch roller 25, and is smoothly fed into the conveyance path 40.

In the present embodiment, as shown in fig. 10, the angle α formed by the guide surface 51 and the bottom surface 53 of the guide member 50 is 30 °, but the present invention is not limited thereto, and a guide surface capable of smoothly correcting a defective banknote P' into a flat shape without interfering with the front surface 52 of the guide member 50 may be formed.

In addition, when the length direction of the transported bill P ' is a ' and the width of the portion of the flaw formed on the bill P ' is J, the width M of the bottom surface 53 of the guide member 50 in the insertion port 33 can be used

2(A’-L/2-J)≥M……(8)

And (4) showing.

As described above, according to the banknote recognition counter according to the second embodiment of the present invention, the guide member 50 provided above the insertion port 33 has the guide surfaces 51a and 51b formed so as to gradually increase the opening areas 34a and 34b toward both ends thereof, and the guide surfaces 51a and 51b are formed so as to: opening areas 34a and 34b converge to 0 as they go from insertion opening 33 to the entrance of conveying path 40. Thus, when a banknote having a flaw such as curling or bending at its end is fed into the insertion port 33, the banknote can be smoothly corrected to a flat shape without interfering with the front surface portion 52 of the guide member 50. As a result, occurrence of a skew or the like which causes a decrease in the pass rate can be prevented, and the banknote counting operation can be improved.

The present invention has been described specifically, but the present invention is not limited to this, and various modifications can be made without departing from the scope of the invention.

The present invention can be applied to a banknote recognition counter: the present invention is useful particularly when it is intended to smoothly feed various banknotes having different sizes or banknotes having defects such as curling (warping) or bending into a machine, by receiving banknotes in a banknote transport unit, recognizing and counting denominations of the received banknotes, and calculating the total amount of the received banknotes or the number of banknotes per denomination.
