Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a paper sheet reversing device for reversing the front and back sides of banknotes, for example.

[Technical background of the invention and its problems]

In recent years, cash sorting and counting machines have been put into practical use that accept banknotes of multiple denominations all at once, automatically inspect them, and sort and count them, and have achieved considerable success.

This cash sorting and tallying machine usually handles 10,000 yen banknotes, 10,000 yen banknotes,
It has a configuration with four accumulation chambers for separately accumulating 1,000 yen banknotes and 500 yen banknotes.

However, in conventional cash sorting and counting machines of this type, when automatically aligning the front and back sides of four types of banknotes, four stacking chambers are allocated two each for stacking clothed bills and two for stacking genuine bills, and the first Two denominations, for example, 10,000 yen banknotes and 10,000 yen banknotes, are designated and the front and back sides are arranged. Next, after taking out the stacked banknotes from each stacking chamber, the front and back sides of the banknotes other than those originally renoected, that is, the 1,000-yen banknotes and the 500-yen banknotes, are arranged. In this way, only two types of banknotes at most can be handled, and when four types of banknotes are handled, twice as much processing time is required, resulting in extremely low processing efficiency.

Therefore, in order to solve this problem, it is necessary to transport the banknotes separately into those that require reversal and those that do not, on the upstream side of the sorting and stacking section, and to reverse the banknotes that require reversal in advance before remerging them. We devised a system that allows four types of banknotes to be stacked face-to-face at the same time.

However, in order to put this into practical use, there is a need for a front-back flipping device that can reliably flip a soft, curly banknote without jamming or skewing it.

On the other hand, there are two typical conventional paper sheet flipping devices: 1. There is a switchback method in which the leading edge of the sheet is brought in so that it is in contact with the stock, and then it is taken out from the rear end to turn it inside out. It is also rotated 180° by the mutually opposing parts of the belt that is stretched around multiple rollers. Twisted conveyance path There is a twisted conveyance path method in which the front and back sides are turned over by sound formation.

However, since the former switchback method leaves the paper sheet in a free state, it is almost impossible to reliably flip the back of the paper sheet if the paper sheet does not have any rigidity. In addition, there is a problem that the transport operation is temporarily stopped, resulting in a large amount of time loss.

On the other hand, the latter type of twisting conveyance method flips the paper inside out while being held and folded, making it possible to turn relatively soft paper sheets upside down. It is not possible to reliably turn paper sheets that are folded or worn out, are weak, and thin, and then handed over. In other words, since the conventional twisting conveyance path system consists of only the twisting conveyance path, the kinks (deformation) of the paper sheets caused by the forced twisting remain untwisted and are carried out. There is a problem that jams are likely to occur.

[Purpose of the invention]

The present invention has been made based on the above-mentioned circumstances, and its purpose is to reliably turn paper sheets from side to side even for folded or weak paper sheets such as banknotes. The aim is to provide equipment.

[Summary of the invention]

In order to achieve this object, the present invention provides a flat conveyance path continuous to the twist conveyance path, and uses the flat conveyance path to correct the curl of paper sheets caused by twisting after turning the front and back sides. It is.

Hereinafter, the present invention will be explained with reference to an illustrated embodiment.

FIG. 1 is a schematic perspective view of a bill sorting and tallying machine to which an embodiment of the front-back reversing device of the present invention is applied, and FIG. 2 is a front view of the entire machine. In the figure, 1 is a main body, and a display operation device 2 is provided in the upper right part of the main body 1, and a bill slot 3 and a bill reject port 4 are also provided. A banknote ejecting device 5 is provided in the main body 1 facing the banknote input port 3, and the banknotes P placed in the banknote input port 3 are sequentially taken out one by one into the take-in conveyance path 6. It is designed so that it can be sent to

Then, the taken-out banknote P passes through a discriminating section 7 that determines the denomination, authenticity, correctness, front and back, etc. of the banknote while being conveyed through the take-in conveyance path 6, and then passes through a 5-ψ. Banknotes P determined to be abnormal by the discrimination section 7 are sent to the banknote reject trojan, and normal banknotes P are guided to the left in the figure by the sorting dart 8. Further, the banknotes P that have been determined to be clothing by the above-mentioned discriminating unit 7 are transferred to the first conveyance path 9.
The banknotes P that have been guided to the back side and determined to be the back side are transferred to the second conveyance path, that is, the front-back reversal conveyance device 1 by the second sorting gate 1°.
It is led to 1 and modified from tails to heads. Also, the above 1st
The passage time of the conveyance path 9 and the second conveyance path (front/back reversal conveyance device) 11 are set to be the same passage time, and the banknotes P... conveyed at a constant pitch are transferred to the second sorting dart. 1
0 and separate conveyance paths 9. Even after passing through II, when merging at the merging section 12, collisions and pitch clogging do not occur, and the merging conveyance is carried out at a constant pitch. Furthermore, the banknotes P, whose front and back sides are aligned, are conveyed to a sorting conveyance path 13 as a sorting section connected to the merging section 12, and are sorted by denomination. and,
Below the sorted conveyance path 13 are banknotes 6 sorted by denomination.
A stacking device [14a
, 14b, I4c, 14d and the banknotes P... accumulated in the stacking devices 14a, 14b, 14C, 14d, and the storage 1 as necessary.
5h, 15b, 15c, and 15d, a shutter device 16 is provided to allow storage. In addition, each storage 15
A pushing device 17 for pushing banknotes P... is provided to ensure storage in the banknotes 8 to 15d.

Next, the second conveyance path, that is, the front-back reversal conveyance device 11
will be explained with reference to FIGS. 2 to 6 (a), (b), and (c).

In FIG. 3, 20 is a twisted conveyance path twisted by 180 degrees, and this twisted conveyance path 20 is 72 as shown in FIG.
It is formed by stretching an elastic endless belt (hereinafter referred to as a twist belt) 21 twisted by 0° (2 rotations) in a figure 8 shape through a plurality of rollers 22a to 22f; As shown in Figure 5, the twisting conveyance path 2θ
A flat twist guide body 23h is placed along both sides of the
, 23b, 23c, and 23d are arranged. These flat plate-shaped twisting guide bodies are supported by pillars (not shown), and the guide bodies 23a, 23b, 23c, and 23d are also paired, and the gaps a shown in FIG. 6(a) are aligned with the twisting of the twisting belt 21. Keep it twisted. These twisting guide bodies 23g to 23c are located on both sides of the twisting belt 21, and are continuous from the opening to the exit of the twisting conveyance path 200 Å, so they are effective for bills P that are folded in four, folded in half, or have a weak texture. The purpose of this is that when a banknote P that is folded in four and has a weak elasticity is conveyed in a 180° inversion at high speed by the twisting belt 2I, the banknote will be bent or skewed (SKEW') due to the wind pressure.
The result will be as shown in Figure 6 (b). In order to prevent this and ensure stable reversal conveyance, it is necessary to firmly back up both ends and guide the guide bodies 23a, 23.
The pair b and the pair 23c and 24d play this role.

Further, in the figure, reference numeral 24 denotes an idle roller, which is located at the center of the twisting belt 21 and provides a clamping force for the banknote P. This is because the twisting belt 21 tries to restore its original shape, so no conveying force can be expected on the twisting conveyance path 20.

Furthermore, if the banknote P is conveyed on the twisting conveyance path 20 without being reversed, it will be conveyed in the shape shown in FIG. This will cause a collision. Therefore, the rollers 24 and 25 located on the twisting conveyance path 20 are connected to the twisting belt 2.
It is necessary to make the width the same as or smaller than the width of .

(See FIGS. 6(a) and 6(b)) In addition, since the banknotes P are forcibly twisted in the twist conveyance path 20, they tend to become curly, and the front banknotes P are conveyed as they are from the first conveyance path 9. When combined with other substances, it is easy to cause a jam. Therefore, a flat conveyance path, such as a horizontal conveyance path 26, is required to correct the curl after reversal. As shown in the box in FIG. 5, at least the horizontal conveyance path 26 for one banknote is configured to merge after correction.

Further, the twisting belt 21 is driven by rotating the drive roller 28 shown in FIG. Furthermore, the drive belt 29
is wrapped around the drive rollers 28 and 30.22d, so that the conveyor belts constituting the second conveyance path (front-back reversal conveyance device #) 11 and the segmented conveyance path 13 rotate. Further, the drive belt 32 is connected to the drive rollers 22d, 3.9.34.
A conveyor belt, which is stretched over and forms the first conveyance path 9 and the reject conveyance path 35, rotates.

Further, among the rollers 22h to 22f, only the roller 22d provided on the exit side of the twisted conveyance path 20 is a driving roller, and the portion of the belt 21 forming the twisted conveyance path 20 and the horizontal conveyance path 26 is tensioned. This prevents the belt 21 from being uneven in speed, sagging, shifting, etc., and it is possible to reliably turn the paper sheets P inside out without causing skews, jams, etc.

When the motor 27 is energized in this way, -10- All conveyance systems rotate at the same speed.

In addition, the first conveyance path 9 and the second conveyance path (front-back reversal conveyance device)
The conveyance distance of 1 is set to be the same, but the belt and
The passing time is not necessarily the same depending on the roller speed, etc. The conveyance distance is corrected by moving the roller 36 for correcting the passage time of the high sugar 1 conveyance path 9 as shown by the broken line in FIG. It is now possible. In this way, the banknotes that have passed through the first conveyance path 9 and the banknotes P that have passed through the second conveyance path (front/back reversal conveyance device #) 11.
The bill pitch at the merging section 12 for the second distribution is not significantly different from the bill pitch in front of the gate 10, and the order of bills will not be changed, there will be no collision, and the operation timing will not be impaired. The structure is as follows.

The banknotes P conveyed by the belt in the take-in conveyance path 6 are discriminated by the discriminator 7, and the banknotes P which are determined to be genuine, false or abnormal are transferred to the first sorting gate 8, where the banknotes P are genuine banknotes. Sorted to the transport section. Next, even if the banknotes P are normal, the banknotes P that are determined to be fronts are guided to the first conveyance path 9, and the banknotes P that are determined to be backs are sorted out at the gate 1o and transferred to the second conveyance path 9.
The paper is guided to the conveyance path (front-back reversal conveyance device) 1. Here, the banknote P determined to be the back is reversely conveyed by the twisting belt 21, but both ends of the banknote P are connected to the guide pairs 23a to 23.
d, the genuine banknote P is conveyed 180° inverted while being firmly backed up and guided, and after being corrected to a clothed banknote P, the twisted conveyance path 20 corrects the curl in the horizontal conveyance path 26, and then the merging portion 12 The front banknotes P sent out from the first conveyance path 9 are merged and conveyed without the pitch between the banknotes being out of order. In addition, the above-mentioned twist guide bodies 23a to 2
The same effect can be obtained even if the twist guides 3d are replaced with wire-shaped twist guides 37a to 37d having a round cross section, as shown in FIGS. 7 and 8, instead of a flat plate.

That is, since the banknote P is conveyed through the twist conveyance path 2o by 1800 rotations, the twist conveyance path 2o is rotated as shown in FIGS.
As shown in , a wire-like twisted guide is formed by winding it in a helical shape at an angle of π a which can be calculated from the width of the guide around the outer periphery of the cylinder 20' and the lead angle θ (-θ-X), which can be calculated from the reversal conveyance distance a. Even if the bodies 37a to 37d are mounted on both sides of the twisting conveyance path 20, it is possible to back up the deflection of both ends of the banknote P and guide it.

In addition, the classified conveyance path 13 separates banknotes P... by denomination, which are conveyed via the first conveyance path 9 and the second conveyance path (front/back reversal conveyance device #) 11 and merged at the merging section 12. It is divided into each of the stacking devices 14h to 14d, and is configured as follows. That is, as shown in FIGS. 10 and 11, the divided conveyance path 13 includes a conveyor belt 41 stretched across a plurality of guide rollers 40, and a conveyor belt 41 on the substantially horizontal lower surface of the conveyor belt 41. The banknote p
It is designed to be held and conveyed in the direction of the l arrow. Also,
Sorting gates 44h, 44b, and 44c, which can be rotated by rotary solenoids (not shown), are arranged at positions corresponding to the first to third stacking devices #14a to 14c, so that the gates move straight in the direction of the arrow. It is possible to guide the banknotes P... to the stacking devices 14a to 14c as appropriate. Further, the banknotes P sorted by the sorting gates 44a, 44b*44c are conveyed through a substantially vertical portion of the conveyor belt 43 and a guide roller 45. Each of the first to
The banknotes P are carried out to the third stacking devices 14a to 14c, and the banknotes P guided to the fourth stacking device 14d are transferred to the conveyor belt 41 and the conveyor belt 43 at the right end in FIG.
It is formed with mutually opposing surfaces and is fed directly at the terminal end of the segmented conveyance path 13. The segmented conveyance path 13 configured in this way conveys the banknotes P sent out from the merging section 12 in the short direction while sequentially sandwiching them via the conveyance belts 41 and 43 . Then, the discrimination section 7
If the denomination of the banknote P being conveyed is, for example, a 10,000 yen banknote as a result of the denomination determination in step 14-, the rotary renoid (not shown) is excited and the classification case 44a is set to the first one.
The banknote P is rotated upward from the state shown in FIG. 0, that is, to the position shown by the solid line in FIG. Thereafter, the rotary solenoid (not shown) is demagnetized and the division gate 44a is returned to the state shown in FIG. 10 (the state indicated by the two-dot chain line in FIG. 11). In the case of 5,000 yen banknotes, the classification case is
The gate 44b operates in the same manner as described above, and in the case of a thousand yen bill, the sorting gate 44c operates in the same manner as described above. In the case of a 500 yen bill, it is naturally conveyed and guided to the end of the divided conveyance path 13 without being sorted on the way. The banknotes P... guided to the sorting conveyance path 13 are sorted into denominations in this way. Next, the stacking device [14a, 14b, 14c,
14d will be explained based on FIGS. 10, 11, and 12. A first accumulating device 14a provided correspondingly below the dividing gate 44th, a second accumulating device 14b provided correspondingly below the dividing gate 44b, and a second accumulating device 14b provided correspondingly below the dividing gate 44c. Third accumulating device 1
4c1 and a fourth stacking device 14d provided below the terminal end of the sorting conveyance path 13 have substantially the same configuration, and after being sorted by the sorting gates 44a to 44c, the output path 47... · Banknotes P carried out by ... or banknotes P carried out directly from the terminal end of the segmented conveyance path 13.
. . , and a stacking chamber 51 that guides and stacks the edges of the banknotes.

The specific configuration of the impeller mechanism 50 and the accumulation chamber 5I is as follows.
As shown in FIGS. 1 and 12, a support shaft 52 is supported by a bearing 54 provided in a side frame 53, and a driven gear 55 is fitted onto the support shaft 52. . The support shaft 42h of the guide roller 42 is attached to the side frame 53, and an intermediate gear mechanism 57 is provided between the drive gear 56 fitted on the guide roller 42 and the driven gear 55. The drive belt 2
When the guide roller 42 is rotated by the rotation of 9, the rotational force is sequentially transmitted to the drive gear 56, the intermediate gear mechanism 57, and the driven gear 55, and the impeller 58 attached to the intermediate portion of the support shaft 52
is set to rotate. The impeller 58 includes a ring-shaped impeller main body 58a, and a plurality of blade plates 58b whose proximal ends protrude radially from the support shaft 52 and are bent in a predetermined direction. It is composed of...

Further, each blade plate 58b is formed in a spiral shape with a wide interval between the tips and gradually narrowing toward the base end. Further, as shown in FIG. 12, the impellers 58, 58 are mounted outside the folds pa and pb of the banknote P at a distance such that the folds pa and pb can be avoided.

Although not shown, it goes without saying that folds can be avoided even if the bill P is folded in half, and especially when setting the 17-spacing of the impeller 58.513, the winding size If we use a large 10,000 yen bill as a standard, we can naturally avoid folding even low-denomination bills. By arranging the impellers 58, 58 in this manner, it is possible to reliably prevent banknotes from jamming at the vane plates 58.58 even if the banknotes P have some creases. Each of the accumulation chambers 51... has a left side wall plate 59 having notches 59a, 59a through which the blade plates 58b, 58b can pass, as shown in FIG.
It consists of a right side wall plate 60 which is arranged opposite to the left side wall 59 with a space where banknotes P can be piled up in a plane direction, and a transparent acrylic plate 61 is provided on the front side so as to be openable and closable. In addition, each of the wall plates 59..., 60.
. . . is constituted by a plate material whose surface is electrically conductive, for example, an embossed metal plate, in both the falling movement direction of the banknotes P, that is, the overlapping of the banknotes P. By configuring each of the 18-wall plates 59 and 60 with metal plates configured in this way, the contact area with the banknotes P can be reduced, so that the banknotes P can be dropped smoothly.
Moreover, the impellers 58, 58 and the conveyor belt) 41,
43 and 46, it is possible to completely eliminate abnormalities in the falling of banknotes P and uneven accumulation due to the influence of static electricity. Incidentally, each of the wall plates 59 and 60 may be replaced with a plate made of embossed plastic plates with conductive metal coated on all sides.

The operation of the thus configured integration devices 14a to 14d will be explained. The banknotes P sorted by denomination by the conveyance path 13 as the sorting section are conveyed to any one of the first stacking device 14h to the fourth collecting fJ device 14d depending on the denomination, For example, the first integration device 14
When a 10,000 yen bill is conveyed to a bank, it is conveyed through the sorting gate 44a toward an impeller 58,58 which rotates in the direction of arrow E shown in FIG.

At this time, the impellers 58 and 58 are rotated at a circumferential speed that is approximately 1/4 of the banknote conveyance speed in the segmented conveyance path 13,
Blade plate of impeller 5FI, 5B, 58b.

Banknotes P are inserted between the blades 58b and conveyed while being sandwiched between the blade plate 58b and the blade wheel body 58a.

Then, as the impellers 58 and 58 rotate, the banknotes P are transferred, and the notches 59a and 5 of the left side wall plate 59 of the accumulation chamber 51 are

That is, when the motor 94 is energized, power is transmitted from the bevel gear 96 to the bevel gear 98, and the arm 95 rotates in the direction of arrow C as shown in FIG. via link 102 and this link 10
Since the frame 9 is attached to the frame 9 through the fixed pin 103, when the arm 100 rotates in the direction of arrow A, the push-in members 92 attached to the frame 91 move into the first position.
As shown in Fig. 5, move downward to the storage compartments 15a to 15d.
It is designed to push in and store the banknotes P that have fallen into the interior.

Also, when the arm 10θ rotates 180°, the frame 9
1 reaches the bottom dead center, is detected by the detector 105, and the pushing operation is completed. In other words, the mechanism is such that the frame 9 moves back and forth once by one rotation of the arm 1θO. Moreover, many of the banknotes P... placed in the respective accumulation chambers 51... are stacked in a standing state as shown in the first accumulation chamber 51 in FIG. P can also be reliably pushed in and stored. That is, as shown in No. 131 I, each wall plate 59, 60 of each accumulation chamber 51... is formed with linear portions 59b, 60b in the falling movement direction of the banknote P side. Linear convex portions 59b..., 60b...
・Insert the push member 92 into the notch 9 so that it is fully inserted.
2a, etc., so that bills that are not stacked horizontally can be reliably pushed and stored. In such a pushing device 17, the banknotes P... accumulated in the plurality of accumulation chambers 51... can be reliably stored into the plurality of storages 15a to 15d at the same time by the - operation, Unlike the structure of Tsuchiki, which constitutes an independent pushing device for the first to fourth accumulation chambers and storage, it is possible to move the first to fourth accumulation sections and storage in one operation. Since it is configured to be pushed in all at once, only one drive device is required, and the number of parts is small, reducing costs.
It can be lowered to about A and has a great effect. The display/operation device 2 is configured as shown in FIG. 17, and includes a power switch 1101, a mode designation switch=29 111, a confirmation key 112, a numeric keypad 113, a group of operation keys 114, a display section 115, a card insertion slot 116, and a slip issuing slot. It consists of 117. The mode designation switch 111 is used to designate a processing mode such as classification, counting, or counting classification. The above operation key group 114 includes a denomination specification key 114cs, an operator number key 114
g and a total key 114h. The display section 115 also includes a display 115a that displays the number of coins for each denomination, a display 115b that displays the number of coins accumulated in each stacking section, a display 115c that displays the total amount, and a display 115e that displays the total number of coins. It is made up of.

The operation of the display operation device 2 configured in this way will be explained. For example, by setting the mode designation switch 111 to counting classification, the control section (not shown) is set to counting classification mode. And account number key 1
14b, the account number indicating the ordinary deposit using the numeric keypad 113, the processing number 30-114c, the operator number key 114d, and the operator number key of the operator using the numeric keypad 113. The account number, processing number and operator number entered using the numeric keypad 113 are displayed on the display 115eK and confirmed. Then, in a standing position, the banknotes P deposited in the ordinary deposit are thrown into the slot 3 at once, regardless of whether they are front or back, and the start key 114f is turned on. Then, the banknote P is transferred to the ejecting device 5, the conveyance path 6, the discriminating section 7, and then the discriminating section 7.
Banknotes that are determined to be front banknotes pass through the first conveyance path 9, and banknotes that are determined to be genuine banknotes pass through the second conveyance path 11, are corrected to face banknotes, merge into a merging section 12, and then are transferred to a segmented conveyance path 13. ,
Accumulating device 14, shutter device 16, pushing device 17
The number of banknotes for each denomination determined by the discriminating section 7 is displayed on the display sections 11 ja and 115 b in correspondence with the stacking section and the denomination. The total amount collected will be displayed on the display 115c. After that, the operator prints the print key 1.
158, the control unit (not shown) prints the account number, processing number, operator number, number of coins for each denomination, amount, and total number and amount using a printer (not shown). Further, time deposits and savings deposits operate in the same manner as described above, and the number of coins and total amount for each denomination are processed together with the account number processing number and operator number.

Although a crank mechanism using a pair of bevel gears 96 and 98 has been described for the pushing drive, other methods are also possible. For example, the same effect can be obtained by using a beer screw at one end of the frame 91 to move it back and forth, and the same effect can also be obtained by replacing it with various mechanisms such as a chain or belt transmission. Needless to say.

In addition, 120 in the figure is a banknote detector that detects the presence or absence of banknotes P.

Note that the present invention is not limited to the above embodiments.

That is, although the description has been given of a device that is applied to a banknote sorting and tallying machine to turn the front and back of banknotes, it goes without saying that it may also be used to turn over paper sheets other than banknotes.

In addition, it goes without saying that the present invention can be modified in various ways without departing from the gist of the invention.

〔Effect of the invention〕

As explained above, the present invention provides a twisted conveyance path that pinches and conveys paper sheets and flips them over as they are conveyed, and a flat conveyance path that is continuous with the twisted conveyance path. An apparatus for reversing paper sheets, comprising: Therefore, curls in paper sheets caused by twisting on the twisted conveyance path can be corrected on a flat conveyance path, and even folded or weak paper sheets such as banknotes can be reliably transported after being turned inside out. It produces such effects.
