Description

According to the present invention, a paper leaf corner fold correction device capable of efficiently correcting corner folds formed on a paper leaf such as a banknote with a simple configuration, a method for correcting the corner fold of the paper leaf by the device, and a paper leaf. Regarding handling equipment.

At various facilities such as financial institutions that handle large amounts of cash, electric railway stations, large-scale retail stores, theme parks, and public gambling venues, banknote handling devices that automate various processes such as banknote counting, sorting, storage, and withdrawal are installed. ing.
Banknotes with broken corners cannot be accepted because they may cause problems such as paper jams in the bill handling device, so they are rejected at the identification stage and discharged to the outside of the machine. Will be flattened and then re-loaded into the device. If the process of flattening the corner-folded portion is manually performed, the work efficiency is lowered when the number of processed sheets is large. For this reason, various devices have been developed that automatically flatten the corner-folded portion of the banknote.

In the banknote repair device according to Patent Document 1, one end of a plurality of repair rods is bundled like an umbrella bone, and a corner fold portion is hooked when sliding on the banknote surface at the tip of each repair rod. A configuration that exerts a repair function by opening and flattening is disclosed.
However, in this configuration, since the correction function acts on only one side of the bill, it is not possible to repair the corner fold that is bent to the back side. In addition, it is clear that the configuration and operation are complicated, leading to an increase in size and cost.

According to the banknote wrinkle smoothing device according to Patent Document 2, a brush body having a shape that expands in a figure eight shape in a plan view in the direction of transporting banknotes and a wrinkle smoothing block are arranged vertically and detachably. By transporting the bill while sandwiching it between the two members, a corner fold portion on the rear end side in the transport direction is caused, and the wrinkles of the bill are smoothed by the pressure of sandwiching the bill from above and below.
However, since the brush body is arranged on the upstream side of the wrinkle smoothing block, if the brush body is strong, the brush body becomes a transport resistance when passing through the creases of the bill before the wrinkle smoothing, and the transport bill is slanted. May cause line or banknote jams. On the other hand, if the brush body is weak, the effect of causing corner breaks is reduced. In addition, since the brush body comes into contact with the banknote and rubs against it, there is a concern about durability such as wear and deformation, and it is difficult to select a brush body that satisfies all of these conditions.

Patent Document 3 and Patent Document 4 also disclose a configuration for correcting a bent portion, but both have problems such as an increase in the number of parts, an increase in size, and an increase in cost.

In the following embodiment, a device for correcting corner folds (corner folds) formed on a banknote as an example of a paper leaf will be described.
Here, the corner-folded portion is a triangular portion formed by folding the corners of a banknote, which should be originally flat, to one side. Straightening is synonymous with straightening and flattening, and straightening a corner fold means that once it is raised, it is flattened to almost the same level as other flat parts of the bill.
In the following description, the front end and the rear end of the bill are based on the transport direction of the bill. Further, the front surface and the back surface of the banknote are based on the posture of the banknote at the time of introduction into the corner fold correction device.

<First Embodiment>
1 (a) to 1 (c) and FIGS. 2 (a) to 2 (c) are external perspective views showing the configuration of the corner fold correction device according to the first embodiment of the present invention. FIG. 3 is a side view of a pair of straightening belts according to the first embodiment of the present invention. Note that FIGS. 1 (b), 1 (c), and 2 show only a pair of straightening belts on one end side in the width direction.

The corner fold correction device 1 according to the present embodiment is located at the front end corner portion and the rear end corner portion of the bill 100 while sandwiching both the front and back sides of the bill 100 transported in one direction (arrow A direction) by the transport means 10. Two sets of straightening belts 20 and 20 forming the posture straightening regions 23 and 23 for stretching the corner-folded pieces 101 to 104 after standing up and the transport roller 12A of the transport means 10 are driven in the direction of arrow A to move the bill in one direction. The transport driving means for transporting the banknotes to the banknotes, the straightening driving means for driving the rollers 22A and 22B of the straightening belt pairs 20 and 20 in the direction of arrow B to correct the broken pieces of the banknote, and the control means for controlling both driving means. It has. The posture correction regions 23 and 23 have a length and a positional relationship through which the entire corner-folded pieces 101 to 104 can pass, and are characterized in that the downstream side in the transport direction extends from the transport path 14 in a laterally widened direction. is there.

The transport means 10 is a pair of endless transport belts 11, 11 (pair of transport belts), each transport belt, which transports the bill 100 in one direction (direction of arrow A) while niping both the front and back surfaces of one bill 100. A pair of transfer rollers 12A and 12B on which 11 and 11 are stretched, and rotation shafts 13 and 13 that rotatably support the transfer rollers 12A and 12B in the direction of arrow A are provided. In each of the transport belts 11 and 11, the transport rollers 12A and 12B rotate in the direction of arrow A, so that the banknote 100 is sandwiched between the two transport belts 11 and 11 and conveyed in the direction of arrow A. The transport belts 11 and 11 hold and transport the posture correction areas 23 and 23 at positions that do not interfere with each other, that is, both the front and back surfaces of the bill 100 in the illustrated example are sandwiched between the widthwise intermediate portions of the bill 100.

The straightening belt pairs 20 and 20 are arranged at both ends in the width direction of the transport path 14, are in the process of being transported by the transport means 10, and are in a state of protruding from both ends in the width direction of the transport belts 20 and 20. Correct the posture while sandwiching the corner-folded pieces 101-104. The lengths and formation positions of the posture correction regions 23 and 23 are set to the lengths and positions through which the entire width direction of the corner folded pieces 101 to 104 formed at the corners of the bill 100 can pass.
Each of the straightening belts 21 and 21 constituting the straightening belt pair 20 is an endless belt stretched by at least two rollers 22A and 22B, and forms a posture correction region 23 between the two straightening belts 21 and 21. As shown in FIG. 3, the straightening belts 21 and 21 are arranged so as to allow the passage of the bill and have a gap G on each side of the bill that comes into contact with the broken corner pieces to cause and correct the broken corners. ing. The gap G between the straightening belts 21 and 21 is set to, for example, about 2 to 3 times the thickness of the bill.
The transport belt 11 and the straightening belt 21 are composed of a belt that exerts a predetermined frictional force (or grip force) on each surface of the bill 100, for example, a rubber belt. The shape and surface condition of the straightening belt 21 are set so as to exert the force necessary for causing the corner folds against the banknote without affecting the transport of the banknote.
For example, the straightening belt 21 may be a circular or elliptical round belt whose cross-sectional shape (the shape of the cross-section in the direction orthogonal to the traveling direction) is sufficiently smaller than the size of the banknote, or the cross-sectional shape may be It may be a belt having a polygonal shape or another shape, or a flat belt having a strip shape. Further, the surface of the straightening belt 21 (the surface facing the bill) may have irregularities or brush-like hairs may be transplanted.

FIG. 4 is a schematic plan view of the corner break correction device.
The posture correction regions 23 and 23 formed by the correction belt pairs 20 and 20 are arranged line-symmetrically with respect to the transport path 14 of the bill 100. That is, the straightening belt pairs 20 and 20 are arranged so that the expansion angles θ1 and θ2 and the transport direction positions are the same with respect to the transport path 14. By arranging the posture correction regions 23 and 23 line-symmetrically with respect to the transport path 14, the correction action of the correction belt pairs 20 and 20 on the bill 100 can be made equal at each end in the width direction. It is possible to maintain the posture of the bills to be transported and to transport the bills 100 straight along the transport path 14.

The expansion angles θ1 and θ2 of the straightening belt pairs 20 and 20 with respect to the transport path 14 may be different from each other. Further, the expansion angles θ1 and θ2 of the straightening belt pairs 20 and 20 may be fixed, but the expansion angles θ1 and θ2 of the straightening belt pairs 20 and 20 with respect to the transport path 14 may be changed.
For example, the support member (not shown) supporting the rollers 22A and 22B of the straightening belt pairs 20 and 20 is reciprocated in the arrow C direction within a predetermined angle range around the roller 22B side located upstream in the transport direction. It is possible, and it may be possible to fix it at an arbitrary expansion angle with a screw or the like so that the expansion angle can be changed / fixed to a desired angle. By configuring the expansion angles θ1 and θ2 of the straightening belts 20 and 20 to be adjustable, the expansion angle of the straightening belts 20 and 20 can be adjusted to the optimum angle according to the angle of the folding line of the angular folding pieces 101 to 104. Since it can be set, the straightening action of the corner broken pieces 101 to 104 by the straightening belts 20 and 20 can be adjusted to the optimum state. It is desirable that the expansion angles θ1 and θ2 are set to be smaller than 45 degrees.
Further, the transport direction positions (positions from the start end to the end) of the posture correction regions 23 and 23 may be different between the posture correction regions 23 and 23, and the transport direction positions of the straightening belts 20 and 20 can be adjusted. It may be configured to change the position of the posture correction regions 23 and 23 in the transport direction. Further, the transport direction lengths of the posture correction regions 23 and 23 may be different between the posture correction regions 23 and 23.

The surfaces of the straightening belts 20 and 20 facing the bill 100 travel in an oblique forward direction (arrow B direction) with respect to the transport direction of the bill 100 by the transport belts 11 and 11 (arrow A direction). The straightening belt pairs 20 and 20 are driven so that the traveling speed thereof is faster than the traveling speed of the transport belts 11 and 11 (banknote transport speed). More specifically, the straightening belt pairs 20 and 20 are driven so that the traveling speed component of the straightening belt pairs 20 and 20 in the direction along the transport direction (arrow A direction) is larger than the transport speed of the bill 100. .. That is, the straightening belt pairs 20 and 20 are driven so that the facing surfaces move relative to the conveyed bill 100 in the diagonally forward direction.

As shown in FIGS. 1 (a) to 1 (c), the corner-folded piece 101, which is located at the tip of the bill 100 (downstream in the transport direction) and is folded on the front side, and the corner-folded piece 102, which is folded on the back side, correct the posture. Upon entering the region 23, the corner-folded pieces 101 and 102 are hooked, scooped up, or caused by contacting the straightening belt pairs 20 and 20 traveling at a speed higher than the transport speed. .. Further, the corner folded pieces 101 and 102 are posture-corrected and flattened while being pressurized when passing between the straightening belts 21 and 21.
As shown in FIGS. 2A to 2C, when the corner-folded piece 104 located at the rear end (upstream side in the transport direction) of the bill 100 and folded on the back side enters the posture correction region 23, the corner is formed. The folded piece 104 is gradually raised by being caught by the straightening belt pair 20 extending in an inclined manner so that the downstream side in the transport direction expands, and the posture is corrected and flattened while being pressurized between the straightening belts 21 and 21. To. The posture correction of the corner-folded piece 103 located at the rear end of the bill 100 and folded to the front side is also performed in the same manner as the corner-folded piece 104.

In this way, in the process of transporting the banknote 100 in one direction (direction of arrow A), the corner-folded pieces 101 and 102 located at the tip of the banknote 100 are driven by the straightening belts 20 and 20 in the direction of arrow B. Further, the corner-folded pieces 103 and 104 located at the rear end of the bill 100 are hooked and scooped up from the straightening belts 20 and 20 by the tapered arrangement in which the distance between the straightening belts 20 and 20 is gradually reduced. Alternatively, the posture is corrected by causing the action.
In this example, the grip force acting on the bill 100 from the straightening belts 21 and 21 is set to be smaller than the grip force acting on the bill 100 from the transport belts 11 and 11. By setting the grip force as described above, it is possible to correct the broken corner pieces without affecting the transportation of the bill 100.
Further, the friction coefficient of the straightening belts 21 and 21 is set to be smaller than the friction coefficient of the transport belts 11 and 11 and to the extent that the broken pieces do not slip. By setting the coefficient of friction as described above, when the corner folds come into contact with the straightening belts 21 and 21, the straightening belts 21 and 21 ensure that the corner folds are caught, scooped up, or caused.

As described above, according to the present embodiment, by transporting the bill in one direction, it is possible to correct both the corner folds at the front end and the corner folds at the rear end of the bill.
In the present embodiment, a straight (or flat) and horizontal transport path 14 is shown, but the transport path may be one for transporting banknotes vertically or an obliquely inclined transport path, and the banknotes may be transported. It may be a curved path that is curved in the transport direction for transport. When the transport path is curved, the posture correction region is formed so as to be parallel to the movement locus (transport locus) drawn by a portion other than the corner-folded piece of the bill to be transported. That is, the posture correction region is formed so as to be curved along the curved transport path and the downstream side in the transport direction expands in the width direction with respect to the transport path. In this way, when the transport path is curved due to layout and space reasons, the posture correction region can be curved according to the curved shape of the transport path, so that the posture of the broken piece can be corrected in a space-saving manner. ..
The posture correction region formed by the pair of straightening belts may be arranged on the same plane (or curved surface) as the transport path (or the bill surface transported by the transport means), or on a different plane (or on a curved surface). (On a curved surface), specifically, it may be arranged at a position where the transported bill is curved in the width direction. Depending on the shape of the transport path or the arrangement of the posture correction region with respect to the transport path, when the bill passes through the posture correction region in a curved posture, the effect of causing the corner folds located on the outer diameter side of the bill is enhanced.

In the first embodiment, the straightening belts 21 and 21 are made to travel at a speed faster than the transport belts 11 and 11, but it is also possible to carry out the straightening belts 21 and 21 in a mode in which the straightening belts 21 and 21 are not driven. When the straightening belts 21 and 21 are not driven, the straightening belts 21 and 21 may not be run (stopped), or may be run along with the movement of the bill due to contact with the bill being transported (rotated around). ) May be done. In the case of rotating around, one or both of the rollers 22A and 22B on which the straightening belt 21 is stretched may be provided with a one-way clutch that allows the straightening belts 21 and 21 to travel only in the forward direction. When the straightening belts 21 and 21 are not driven, the straightening belts 21 and 21 mainly straighten the corner-folded pieces 103 and 104 at the rear end of the bill, but the tip of the bill 100 is conveyed in one direction. It is also possible to correct the corner folds 101 and 102 in the portion.

It forms an introduction part (paper leaf introduction part) 24. The straightening belt pair 20 forms the bill introduction portion 24 by expanding the end portion on the upstream side in the transport direction in a tapered shape.
The straightening belts 21 and 21 constituting the straightening belt pair 20 are endless belts. The straightening belts 21 and 21 form a bill introduction portion 24 between at least two rollers 22A and 22B forming a posture correction region 23 between the straightening belts 21 and 21 and a roller 22B between the straightening belts 21 and 21. It is stretched by a roller 22C.
As shown in FIG. 6, the straightening belts 21 and 21 allow the bills to pass through in the posture straightening region 23, and have gaps on each side of the bills that come into contact with the broken corner pieces to cause and correct them. .. Further, the distance between the straightening belts 21 and 21 in the bill introducing portion 24 is widened in a tapered shape on the upstream side (banknote introducing side) in the transport direction, so that the bill 100 can be easily introduced into the posture correction region 23. There is. Therefore, when straightening the corner-folded piece of the bill 100, it can be straightened smoothly without giving a large load to the bill 100 and damaging it.

<Summary of Examples of Embodiments of the Present Invention, Actions, and Effects>
[First Embodiment]
The paper leaf corner fold straightening device 1 according to this embodiment sandwiches both sides of the paper leaf (banknote 100) transported in one direction, and has corner fold pieces at the front end corner and the rear end corner of the paper leaf. Straightening belt pairs 20 and 20 forming the posture correction region 23 for extending 101 to 104 after standing are provided at both ends in the width direction, and the posture correction region has a length and a positional relationship through which the entire corner-folded piece can pass. However, it is characterized in that the downstream side in the transport direction extends from the transport path 14 in a laterally widened direction.

In paper leaf counting, sorting and sorting operations, automation is desired in order to eliminate the complexity of the work, improve efficiency, and improve security such as fraud prevention. Paper leaf sorters (banknote sorters) that support counting, sorting, and sorting reject square-folded paper leaves (banknotes), which must be manually corrected by workers for recounting, reclassification, and sorting. .. However, although the work of extending the corner fold is particularly troublesome and leads to a decrease in efficiency, the present invention enables automation. The same applies to paper leaves with wrinkles and creases.
In this embodiment, the corner folds of the paper leaf being conveyed are straightened by sandwiching the widthwise end of the paper leaf with a pair of straightening belts. By arranging a pair of straightening belts at both ends in the width direction, it is possible to straighten the corner folds at each end in the width direction. Further, by sandwiching the broken pieces with a pair of straightening belts, the broken pieces on both the front and back sides of the paper leaf can be corrected.
Since each straightening belt pair extends laterally from the transport path on the downstream side in the transport direction, the corner folds located at the rear end of the paper leaf are in the process of transporting the paper leaf in one direction. Posture is corrected by arranging a pair of correction belts.
Here, the straightening belt pair may be driven by a drive source or may be carried along with a paper leaf. When traveling by a drive source, the paper leaf is conveyed in one direction by driving so that the surface of the straightening belt pair facing the paper leaf moves diagonally forward with respect to the paper leaf transport direction. In the process of doing so, both the corner folds located at the tip of the paper leaf and the corner folds located at the rear end of the paper leaf can be corrected. When the drive source is not used, the straightening belt pair mainly corrects the corner folds located at the rear end of the paper leaf, but it is located at the tip of the paper leaf in the process of transporting the paper leaf in one direction. It is also possible to correct the broken corners.

The shape of the transport path is linear, curved, horizontal, vertical, diagonal, etc., depending on the layout and space in the paper leaf handling device (banknote handling device) in which the corner fold correction device is housed. Can be designed. Further, the straightening belt pair is arranged according to the shape of the transport path so that the posture correction area is parallel to the transport path. Further, the angle of the straightening belt pair with respect to the transport path, the position in the transport direction, and the like are set so as to be optimum according to the shape of the corner-folded piece of the paper leaf.
According to this aspect, it is possible to straighten the broken pieces at each corner of the paper sheet simply by arranging the straightening belt pairs at both ends in the width direction. Therefore, the number of parts can be reduced, the size can be reduced, and the structure can be simplified. It is possible to provide a corner fold straightening device that can realize cost reduction and correct all corner folds on both the front and back sides.
