Description

According to the present invention, a corner fold correction mechanism for a paper leaf and a corner fold correction mechanism for a paper leaf can be used to efficiently correct a corner fold formed on a paper leaf such as a banknote with a simple configuration. Regarding the method and the paper leaf handling device.

Various facilities such as financial institutions, electric railway stations, large-scale retail stores, theme parks, and casinos that handle large amounts of cash have introduced banknote handling devices that automate various processes such as counting, sorting, storing, and paying out banknotes. ..
Banknotes with corner folds at the corners cannot be accepted because they can 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. After flattening the part, it will be put back 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 both 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 a corner fold 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 this embodiment, a mechanism for correcting mainly triangular 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 quadrangular bill, which should be originally flat (extended state), to one side or the other side. The corner folds may have a quadrangular shape or other indefinite shape in addition to the triangular shape, but a triangular fold portion as a typical example will be described.
Straightening is synonymous with straightening, flattening, and stretching, and straightening a bent part is almost the same level as other flat parts of a banknote after causing a bent triangular corner part of the banknote body. It means to expand and flatten (return to the original shape).

[First Embodiment-Basic configuration]
The corner-folded portion correction mechanism 1 of the paper sheet is arranged so as to face each other substantially in parallel with a space S of L3 having a shorter interval than the longitudinal length L1 of the banknote (paper sheet) 100, and guides for passing the banknote and suspending the banknote. Two guide members 10 and 40 having vacant spaces 13 and 43 at equivalent opposite positions (height direction position and lateral direction position), and each guide empty along the inner surfaces 10a and 40a of the two guide members. A pressure member 60 that advances and retreats in the space S along a movement path P that intersects (orthogonally) the bill surface (upper surface) 100a that supports both end pieces 101a and 101b, respectively, by the places 13 and 43, is provided. When the pressurizing member 60 is moved from the upper side to the lower side of the space S while both end pieces 101a and 101b of the bill are supported and suspended by the guide vacant spaces 13 and 43, the bill surface located in the middle is pressed. The banknotes are pushed in and moved downward while deforming the entire banknote into a U-shape so that the ends 101a and 101b of the banknotes are gradually separated from the guide vacant spaces 13 and 43, and further to the guide members 10 and 40. It is characteristic that the pressurizing member 60 is provided with corner-folded portion straightening portions 15 and 45 for correcting the corner-folded portions 105 and 110 of the bill in the process of separating both end pieces 101a and 101b of the bill from the guide vacant spaces. is there.

In this example, by connecting the lower ends of the guide members 10 and 40 which are vertically arranged with respect to each other via the space S by the connecting member 55, the corner bent portion correction mechanism 1 is moved up and down. An elevating space for the pressurizing member 60 penetrating in the direction is formed.
In the process of moving the banknote end pieces 101a and 101b downward, the corner-folded portion straightening portions 15 and 45 are flattened after being raised by hooking the corner-folded portion 105 on the front surface side while being in contact with the surface 100a of the banknote. In the process of moving the bill end pieces 101a and 101b downward with the pair of left and right first corner folds straightening edges 17 and 47, the corner folds 110 on the back side are hooked and stood up while being in contact with the back side 100b of the bill. A pair of left and right second corner folds straightening edge 27s and 57s are provided, respectively.
Further, one corner fold straightening portion, in this example, the first corner fold straightening end edges 17 and 47 are provided on the upper end edges (tip edges) of the guide members 10 and 40, and the other corner fold straightening portion is straightened. The portion, in this example, the second corner-folded portion straightening edge 27, 57 is provided on the lower end edge of the inner surface (inner circumference) of each of the guide vacant spaces 13 and 43.

As shown in FIG. 2B, the guide members 10 and 40 are located in the upper inner portion of the first thin plate-shaped guide pieces 11 and 41 and in the lower outer side of the first guide pieces 11 and 41. The second guide pieces 12 and 42 in the shape of a thin plate are provided, respectively. That is, the first guide pieces 11 and 41 are inside and above the second guide pieces 12 and 42.
The left and right ends of the first guide piece 11 and the second guide piece 12 in front view are connected by a vertically extending end connecting piece 14a, and the left and right ends of the first guide piece 41 and the second guide piece 42. The ends are connected by a vertically extending end connecting piece 14b.

As shown in FIGS. 1 and 2 (a), the first corner folds inclined (approximately in a C shape) diagonally downward to the left and right of the upper end edges of the first guide pieces 11 and 41, respectively. Part-correcting edge (first corner-folded part-correcting part) 17 and 47 are arranged, and the left and right upper edges of the substantially trapezoidal second guide pieces 12 and 42 have diagonally downward hem spreads (substantially c). The second corner fold correction edge (second corner fold correction portion) 27, 57 which is inclined (in a character shape) is arranged.
The width of each edge of the corner fold straightening edge 17, 47 for upward corner fold correction and the corner fold straightening edge 27, 57 for downward corner fold correction is left and right toward the tip (upper end). By gradually reducing the number of banknotes evenly, it is possible to sequentially raise and flatten the triangular corners at the corners of the banknote.
In the illustrated example, each straightening edge extends in a straight line (straight taper shape), but it may extend in a curved convex shape or a curved concave shape (curved taper shape).

The width dimensions L5 and L6 of the corner-folded edge correction edges 17, 47, and 27, 57 with respect to the bill width L2 should be set so as to correspond to approximately 1/4 to 1/3 of the bill width L2, respectively. For example, it can correspond to most of the corner folds that are normally formed (see FIGS. 1 and 2). If the ratio of the corner fold size to the paper leaf size differs greatly due to special circumstances such as the material and wall thickness of the paper leaf to be handled, the width dimensions of the corner folds straightening edge L5, L6, etc. Each condition such as the inclination angle and the length may be adjusted as appropriate. Therefore, the above dimensional ratio is only an example.
Further, each edge portion of each of the straightening edge edges 17, 47, 27, and 57 is gradually reduced in a tapered shape toward the tip, so that the upward angle folding portion 105 and the bill body are facing downward. The corner fold portion 110 and the bill body are easily inserted, and the corner fold portion is easily folded back.

The guide vacant spaces 13 and 43 according to this example are the upper guide vacant spaces 13a and 43a extending horizontally and the lower guide vacant spaces extending diagonally downward from both ends in the longitudinal direction of the upper guide vacant spaces. It has a symmetrical shape with the portions 13b and 43b. In this example, the guide vacant spaces 13 and 43 are provided at the same positions facing each other of the guide members 10 and 40 in the same shape.
The corner fold straightening edge 27, 57 for downward corner fold straightening is provided at a position corresponding to the lower end edge of the inner surfaces (inner circumferences) of the guide vacant spaces 13 and 43.
The corner fold straightening portions 15 and 45 are arranged in a range and a position where the upward (front surface side) corner folds 105 formed in the left and right corners of the bill 100 can come into contact with the corner folds 105. Further, the corner folds straightening edge (upper edge) 17 and 47 for correcting the upward corner folds in contact with the upper surface (surface) 100a of the bill end piece, and the downward (downward corners) formed at the left and right corners of the bill 100. Corner fold straightening edge for downward corner fold straightening, which is arranged in a range and position where the corner fold 110 (on the back side) can come into contact with them when passing through, and is in contact with the lower surface (back side) 100b of the bill end piece. (Lower edge) 27 and 57, respectively.

The pressurizing member 60 has a bottom surface 61 that presses the surface of the bill when descending, and two side surfaces 62 that are in sliding contact with the inner surfaces 10a and 40a of the two guide members 10 and 40 at the same time.
As the pressurizing member 60 descends, the banknote end pieces 101a and 101b bent upward by about 90 degrees as shown by the broken line in FIG. 2B descend along the outer surfaces of the first guide pieces 11 and 41. In the process, first, the corner folds 105 are gradually expanded while starting contact with the corner folds straightening edges 17, 47, and then the corner folds 110 are contacted with the corner folds straightening edges 27, 57. It is gradually expanded while starting contact.
The inclination angle θ (FIG. 2A) of each corner bent portion straightening edge 17, 47, 27, 57 is set so that the spreading operation is smooth. In addition, since the triangular bent pieces have various shapes and sizes, each corner bent portion straightening edge 17, 47, 27, can be corrected so as to be able to correct any shape and size of the corner broken piece. The formation position, shape, etc. of 57 are selected.
Further, by forming the upper end portions of the corner-folded portion straightening edge 17, 47, 27, 57 into a curved shape as shown in the drawing, the banknote when the upper end portion comes into contact with the corner-folded portions 105, 110. It is possible to reduce the damage to and cause the subsequent corner folds, and to smooth the deployment work.

When the bill 100 is in the flat initial state shown in FIG. 3, the upper surface of the intermediate portion is pressed downward by the pressurizing member 60, so that both end pieces 101a and 101b of the bill 100 are initially folded diagonally upward (FIG. 3). (Refer to the two-dot chain line in 4), the central portion of the bill further descends to simultaneously start descending in the upper guide vacant portions 13a and 43a, and then the first guide as shown in FIGS. 5 (a) and 5 (b). Descend in a substantially vertical posture in the gap between the piece 11 and the second guide piece 12 (guide space 13) and the gap between the first guide piece 41 and the second guide piece 42 (guide space 43). I will go. At this time, the corner folds straightening edge edges 17 and 47 for correcting the upward corner folds are in sliding contact with the upper surface 100a of the bill to allow the bill body to pass through, and the upward corner folds at the rear end corner of the bill are allowed. When the hem portion of the portion 105 starts contacting the edges of the corner-folded portion straightening edge edges 17 and 47, the hem portion is pressed in the direction of deploying the edge and finally flattened. In this example, the upward corner fold portion 105 is formed only at the rear end portion of the bill, but the same processing is performed when there is a corner fold portion on the front end side.

Further, when both end pieces 101a and 101b of the bill 100 pass downward at the same time in the upper guide vacant portions 13a and 43a by pressing the intermediate portion downward by the pressurizing member 60, the downward angle fold portion is corrected. The corner fold straightening edge 27, 57 is formed when the hem of the downward corner fold 110 at the rear end corner of the passing banknote starts to contact the edge of the corner fold straightening edge 27, 57. Finally, straighten it flat while applying pressure in the direction of unfolding. In this example, the downward corner fold portion 110 is formed only at the rear end portion of the bill, but the same processing is performed when there is a corner fold portion on the front end side.

The bill 100 is conveyed by a paper feeding mechanism including a roller (not shown) arranged on the front side of the guide member 10 on the front side, the tip edge is inserted into the guide space 13 on the front side, and then the guide on the back side. Both ends 101a and 101b of the banknotes that are inserted into the vacant space 43 and stretched flat as shown in FIG.
Since a banknote is generally rectangular, correction is usually performed in the process of lowering both ends in the longitudinal direction of the banknote by pushing down the central portion in the longitudinal direction of the banknote with a pressurizing member. It is also possible to perform correction in the process of pushing down the part and lowering both ends in the lateral direction.
Since banknotes have a certain waist (elasticity), as shown in Fig. 3, it is normal to maintain a nearly flat posture as a whole when both ends are supported by guide vacant spaces. The corner-folded portion correction mechanism of the present invention can be used even if the surface is not completely flat, such as the central portion of the bill being deformed into a concave shape or a convex shape. Further, even if the end piece is deformed, there is no problem in correcting the broken corner.

The pressurizing member 60 is configured to move up and down in the space S along the movement path P by an elevating mechanism such as a motor (not shown). A thin plate-shaped friction member 63 (shown by a broken line in FIG. 2B) made of rubber or the like having a large frictional resistance is arranged on the bottom surface 61 of the pressure member so as not to cause slippage when pressing the surface of the bill. I will do it. This is because when slippage occurs between the bill surface and the bill surface, both ends cannot pass through the guide vacant spaces 13 and 43 at equal speeds, causing skew (tilt). The skewed banknote cannot be sufficiently corrected because the corner fold cannot properly contact the corner fold correction edge, and the banknote is completely shown in FIG. 10 when the pressurization by the pressurizing member is completed. It becomes impossible to shift to a state of withdrawal. Further, even if skew does not occur, the correction timing (lowering timing) of both ends varies, so that the banknote cannot shift to the completely detached state shown in FIG. 10 when the pressurization by the pressurizing member is completed.

[First Embodiment-Explanation of Corner Bent Correction Operation]
An operation of correcting the corner folds 105 and 110 provided on the front side and the back side of the trailing edge of the bill by the corner fold correction mechanism 1 of the bill having the above configuration will be described.
In the initial stage of the straightening operation, first, in the initial insertion state shown in FIG. 3, the pressurizing member 60 is lowered into the space S along the movement path P as shown in FIG. In the state of FIG. 4, the bottom surface 61 of the pressurizing member 60 is in contact with the top surface 100a of the bill, and pressurization has not started.
Next, in the first pressurizing state immediately after the pressurizing member 60 shown in FIGS. 5 (a), 5 (b), 6 (a), and (b) starts pressurizing, the pushing amount is small. Therefore, the bill end pieces 101a and 101b are bent diagonally upward at a position corresponding to the bottom corners 61a and 61b of the pressurizing member or the upper end edges of the inner surfaces (inner circumferences) of the guide vacant spaces 13 and 43, and then vertically. It transforms into a posture. At this point, the upward corner fold 105 is above the corner fold straightening edge 17 and is in a non-contact state, and the downward corner fold 110 is above the corner fold straightening edge 27 and is non-contact. Since they are in a state, none of them have been corrected.
Next, in the second pressurized state shown in FIGS. 7 (a) (b) and 8 (a) (b), the upward corner fold portion 105 has already descended and passed through the corner fold portion straightening edge 17. While it is in a straightened state, the downward corner fold portion 110 is in an uncorrected state because it has not reached the corner fold portion straightening edge 27.
Next, in the third pressurized state shown in FIGS. 9A and 9B, the downward corner fold portion 110 reaches the corner fold portion correction edge 27 and is in a state of being corrected.
In FIG. 10, which shows the fourth pressurized state, since the both end pieces 101a and 101b of the banknote are separated from the guide member after the pressurization is completed, the banknote with the corner folds corrected is flattened as a whole. I'm back.

In the present embodiment, the first guide pieces 11 and 41 located inside and above and the second guide pieces 12 and 42 located outside and below the guide pieces 12 and 42 sandwich the guide vacant spaces 13 and 43 in between. They are arranged in a staggered manner. That is, the internal / external and vertical positions of the first guide pieces 11 and 41 and the second guide pieces 12 and 42 are deviated from each other with the guide vacant spaces 13 and 43 in between. Therefore, as shown in FIG. 2B, when the pressurizing member 60 is pushed into the space S to pressurize the central portion of the bill, the upper end edges (inner circumference) of the inner surfaces (inner circumferences) of the guide vacant spaces 13 and 43 ( When each end piece begins to bend upward from the linear bent portion of the bill end pieces 101a, 101b in contact with the lower end edges 11a, 41a) of the first guide pieces 11, 41, the bill end piece is surely and smoothly. As the pressurizing member 60 further descends, the upper surface (inner side surface) of each end piece is smooth along the outer surface of the first guide pieces 11 and 41 and in surface contact with the outer surface. You can descend while sliding on. Therefore, the upward corner folds 105 can be reliably hooked and unfolded by the corner folds straightening edge 17, 47, and the posture can be corrected flatly.
Further, in the process of lowering the pressurizing member 60, the lower surfaces (outer surfaces) of the end pieces 101a and 101b can be lowered while smoothly sliding while in surface contact with the inner side surfaces of the second guide pieces 12 and 42. .. Therefore, the downward corner folds 110 can be reliably hooked and deployed by the corner fold correction edge 27s and 57s, and the posture can be corrected flatly.

The vertical distance between the lower end edges 11a and 41a of the first guide pieces 11 and 41 and the upper end edges of the second guide pieces 12 and 42, which are arranged so as to be offset from each other in the vertical position and the inner and outer positions, is appropriately narrow. By setting the interval C, when the front surface of the bill is pressed by the pressurizing member 60, the end pieces 101a and 101b can be deformed upward with good responsiveness, quickly, and at the same time. Further, by setting the interval C to be appropriately narrow, the movement of the bill end pieces can be regulated and the rampage can be minimized.
In the example of FIG. 2B, the positions of the outer surface of the first guide pieces 11 and 41 and the inner surface of the second guide pieces 12 and 42 are arranged along substantially the same plane (inner and outer positions). However, this is an example, and the inner surface of the second guide pieces 12 and 42 is located closer to the outside than the outer surface of the first guide pieces 11 and 41 by a distance of about the thickness of one bill. It may be misaligned.
It is preferable to appropriately adjust the positional relationship between the outer surface of the first guide pieces 11 and 41 and the inner surface of the second guide pieces 12 and 42 depending on the thickness and material of the bill to be handled.

Further, in FIG. 2B, the outer surfaces of the first guide pieces 11 and 41 and the inner surfaces of the second guide pieces 12 and 42 are arranged so as to be at the same level, but this is an example. , The inner side surface of the second guide pieces 12 and 42 may be slightly recessed inward from the outer surface of the first guide pieces 11 and 41.
Further, although not particularly shown, the corner-folded portion-corrected edge edges 17 and 47 and the corner-folded portion-corrected edge edges 27 and 57 are extended vertically downward without shifting the positions in the inward and outward directions. The corner fold correction edge 27s and 57s may be located at the locations.

In order to simultaneously lower the end pieces 101a and 101b protruding outward from the guide vacant spaces 13 and 43 when the pressurizing member 60 descends in an appropriate posture, the side surface 62 of the pressurizing member is possible. It is preferable that the guide members 10 and 40 are brought close to the inner surfaces 10a and 40a as much as possible.
Specifically, the corner folds are formed by forming a slight gap between the side surfaces 62 of the pressurizing member and the inner walls 10a and 40a of each guide member to squeeze and push the bill. It is possible to regulate the corner fold so that the corner fold is separated from the corner fold when it comes into contact with the part correction portion, and the corner fold can be reliably corrected.
By the work of lowering the pressure member 60 only once in this way, the corner folds on both the front and back surfaces can be sequentially corrected, the device configuration can be simplified, and the work time can be shortened.
In this example, a configuration example in which the pressurizing member is lowered from above with respect to the upper surface of the horizontally supported banknote is shown, but this is an example, and the pressurizing member is lowered with respect to the lower surface of the horizontally supported banknote. It is also possible to reverse the top and bottom so as to pressurize in the process of raising. Further, the technical scope of the present invention also includes a configuration in which a pressure member is pressure-deformed by moving a pressure member in a lateral direction or an oblique direction with respect to one surface of a bill supported in a vertical posture, an inclined posture, or another posture. It is clear that it belongs. This applies to all of the following embodiments:

<Second Embodiment>
Next, FIG. 11 is a vertical cross-sectional view of a main part of the second embodiment of the corner-folded portion correction mechanism 1 of the paper leaf of the present invention, and the first guide pieces 11 and 41 and the second guide pieces 12 and 42. It is characteristic that the positional relationship is opposite to that of the first embodiment.
That is, in the present embodiment, the first guide pieces 11 and 41 are located on the upper outer side, and the second guide pieces 12 and 42 are located on the lower inner side.
Even with this configuration, the corner-folded portion-correcting edge edges 17 and 47 provided on the first guide pieces 11 and 41 can correct the posture of the upward corner-folded portion 105 of the banknote and flatten it. The corner-folded portion-correcting edge 27, 57 provided on the second guide pieces 12, 42 can correct the posture of the downward corner-folded portion 110 of the banknote and flatten it.

In this example, since the inner side surface of the second guide pieces 12 and 42 is located inside the inner side surface of each of the first guide pieces 11 and 41, each side surface of the pressure member 60 is lowered. The space between the 62 and the inner side surfaces of the second guide pieces 12 and 42 can be narrowed to an appropriate distance of about the thickness of one bill. For this reason, in the process of the banknote end pieces passing through the guide vacant spaces 13 and 43 and descending, they are squeezed between the side surface of the pressure member and the inner side surface of the guide piece of the guide, and the flattened corner folds. It is possible to form an elongation habit with respect to the part.
It should be noted that by inclining the portions corresponding to the corner-folded portions straightening edges 17 and 47 of the first guide pieces 11 and 41 outward as shown by the broken lines in the figure, each guide is emptied by the lowering of the pressurizing member 60. When the banknote end pieces 101a and 101b protruding outward from the places 13 and 43 are bent upward and then descend together with the pressurizing member, the upward corner fold portion 105 is formed at each corner fold portion straightening end. The edges 17 and 47 allow for reliable hooking and flattening.
In the first embodiment as well, as in the present embodiment, the portions of the first guide pieces 11 and 41 corresponding to the corner-corrected edges 17 and 47 may be inclined outward.
That is, in any of the embodiments, the standing postures of the first guide pieces 11 and 41, particularly the extending direction of the straightening edge of each corner fold, need not be vertical, and the material and meat of the paper leaf to be straightened do not need to be vertical. It may be inclined according to various conditions such as thickness.
The procedure, action, and effect of the corner fold correction of the second embodiment are the same as those of the first embodiment.

<Third Embodiment>
Next, FIG. 12 is a front side perspective view showing the configuration of the third embodiment of the corner-folded portion correction mechanism 1 of the paper leaf of the present invention. The same parts as those in the first embodiment are designated by the same reference numerals, and duplicate description will be omitted.
The difference between this embodiment and the first embodiment is that the guide vacant spaces 13 and 43 are not closed spaces, but are notched at one end in the lateral direction (end connecting pieces 14a and 14b) of the first guide pieces 11 and 41. The point is that a part of the space is open due to the formation of 11a and 41a.
In the first embodiment in which the guide vacant spaces 13 and 43 are closed spaces, in order to insert the bill 100 into the space S, the tip of the bill is inserted from one guide vacant space 13 and then the tip from the other guide vacant space 43. However, in the present embodiment, the banknotes can be inserted into the guide space S from the lateral direction by using the notches 11a and 41a as shown by the arrows. That is, the notches 11a and 41a as the bill introduction ports are formed at positions orthogonal to the guide vacant space 13 which is the bill introduction port in the first embodiment.
With such a configuration, there is an advantage that the variation in the direction in which the bill is sent to the corner-folded portion correction mechanism 1 of the bill can be increased.
The pushing operation by the pressurizing member 60 starting from the initial storage state in which the banknotes are introduced into the space S and supported by the end pieces 101a and 101b of the banknotes by the guide spaces 13 and 43 is the same as in the first embodiment.
Except for the direction in which the banknotes are introduced, the action and effect of the corner fold correction according to the third embodiment are the same as those of the first embodiment.

<Application example 1 of the paper leaf corner break correction mechanism>
[Explanation of banknote handling device]
FIG. 13 shows a configuration example of a bill handling device (paper leaf handling device) in which a corner fold straightening device that automates the straightening work by the paper leaf corner fold straightening mechanism of the present invention is applied to a bill sorting machine (paper leaf sorting machine). It is explanatory drawing which shows.
The bill handling device 250 includes a bill sorting machine 200 and a bill corner fold straightening device 260 using the bill corner fold straightening mechanism 1 according to each of the above embodiments.
The banknote organizer 200 has a paper feed unit 201 that separates a large number of banknotes set on the bottom plate one by one from the bottom and feeds them out to a transport path, and a corner-folded portion of the banknotes that have been fed out from the paper feed unit 201. The bill identification unit 205 for determining the presence / absence, denomination, authenticity, etc., the bill storage unit 220 for accommodating the bills determined to be acceptable by the bill identification unit 205, the transport mechanism 230, and the control means 240. It has a rough outline.

The paper feed unit 201 includes a bottom plate 201a for loading banknotes, a paper feed roller 201b for feeding out the bottommost banknotes, a separation roller 201c for separating the banknotes fed in the double feed state, and the like.
The transport mechanism 230 includes transport members such as belts and rollers, and a motor that drives them.
When the bill identification unit 205 determines that the bill delivered from the paper feed unit 201 is a bill that cannot be accepted because it has a corner-folded portion, the control means 240 drives the transport mechanism 230 to drive the bill. Is conveyed to the corner fold straightening device 260, and the corner fold is straightened so that it can be accepted.
The corner-folded portion straightening device 260 is a means for correcting the corner-folded portion after receiving a rejected bill determined to be unacceptable by the bill identification unit 205 due to the presence of the corner-folded portion. The banknotes are provided with a corner-folded portion straightening mechanism 1, a storage section 262 for accommodating the banknotes that have been straightened, and a control means 263. The corner-folded bill loading section 261 includes a bottom plate 261a for loading square-folded bills, a paper feed roller 261b for feeding out the corner-folded bills at the bottom, a separation roller 261c for separating the corner-folded bills fed in a double-feeding state, and the like. There is.
The banknotes having the corner folds supplied from the corner fold bill loading unit 261 are stored in the storage unit 262 after the corner folds are eliminated by the above-mentioned correction operation in the corner fold correction mechanism 1.
The banknotes whose corners have been corrected in the storage section 262 are reset in the paper feed section 201 of the bill sorting machine 200 and are identified, and then transported and stored in each bill storage section 220.

Instead of the bill organizer, various vending machines, money changers, money payout machines, and other various money handling devices can be applied.
According to this device configuration, it is possible to correct the corner folds of banknotes in the pre-process of counting, sorting, and sorting banknotes, and to collect and collect them. Therefore, inevitably, the banknote counting, sorting, and sorting operations in the post-process are performed. Efficiency can be improved.
The bill handling device 250 can be used not only for bills but also for securities, tickets, ballots, and various other bills for correcting corner folds.

[Processing procedure by banknote handling device 250]
FIG. 14 is a flowchart showing a processing procedure by the bill handling device 250 including a bill corner fold straightening procedure by the corner fold straightening device 260.
In step S1, paper feeding is started from the paper feeding unit 201, and in step S2, it is determined whether or not the bill fed by the bill identification unit 205 is a square-folded bill (rejected bill) having a square-folded portion. If it is a corner-folded bill, it is transported to the corner-folded portion correction device 260, and if it is not a corner-folded bill, it is transported to the bill accommodating portion 220 and stored (steps S3 and S4).
In the corner-folded portion correction device 260, the corner-folded bills loaded on the corner-folded bill loading unit 261 are fed one by one to the corner-folded portion straightening mechanism 1 (step S5).

In the corner bending portion correction mechanism 1, each end piece of the paper leaf is inserted into each of the guide vacant spaces 13 and 43, and each end piece is supported by each guide vacant space. each end piece 101a member 60 pushes the surface middle part of the paper, by moving 101b and along the guide member 10, 4 0, folded corner portions in the course of each end piece is moved along the guide member Step S7 in which the corner-folded portions 105 and 110 of the front and back sides of the paper sheet are sequentially corrected by the straightening portions 15 and 45, and the pressure member is moved to the pushing end position to separate each end piece from each guide member, and then added. Step S8 for returning the compression member to the initial position is performed.
In step S9, the presence or absence of banknotes in the paper feed unit 201 is checked, and if there are banknotes, the process returns to step S1 and the same routine as above is repeated, and if there are no banknotes, the process ends.

When the pressurizing member 60 is lowered and the central portion of the banknote in the initial insertion state shown in FIG. 3 is pushed downward, the bill end pieces 101a and 101b protruding from the guide vacant spaces 13 and 43 are the bottom surfaces of the pressurizing member. While bending upward along each lower end edge 61a (FIG. 2A) in the front-rear direction of 61, the upper surface (inner side surface) of each end piece 101a, 101b is in contact with the outer surface of the first guide pieces 11, 41. It goes down while letting it go. In the process of lowering the end pieces 101a and 101b, a part of the upward corner fold portion 105 comes into contact with the one corner fold portion straightening end edge 17 at the corresponding position. Subsequently, when the end piece is lowered, the portion of the corner-folded portion straightening edge 17 with which the corner-folded portion 105 comes into contact is sequentially displaced downward. Since the corner-folded portion straightening edge 17 expands diagonally outward as it goes downward, the corner-folded portion 105 receives a force in the direction of being pushed out from the contact portion with the corner-folded portion straightening edge 17 at the end. Flatten to the same level as the other end pieces. This straightening operation is also the same in the relationship between the downward corner fold portion 110 and the corner fold portion straightening edge 27 at the corresponding position.
In this example, the example in which the corner folds 105 and 110 are formed only on the front end piece 101a of the banknote has been described, but the corner folds 101b on the back side of the banknote are formed with upward and downward corner folds. The same applies to the relationship with the edge correction edges 47 and 57 of the corner folds in the case of
The banknotes whose corners have been corrected and accumulated in the storage section 262 are reset to the paper feed section 201 of the bill sorting machine and are stored in the storage section 220 through the above procedure.
In this way, since the corner breaks are corrected and aggregated / accumulated in the pre-process of the banknote counting / sorting / sorting work, the efficiency of the banknote counting / sorting / sorting work in the post-process can be inevitably improved. ..

<Application example 2 of the paper leaf corner fold correction mechanism>
[Explanation of banknote handling device 300]
FIG. 15 shows a configuration of a bill (paper leaf) handling device in which a corner fold straightening device 350 that automates a straightening operation by the paper leaf corner fold straightening mechanism 1 of the present invention is applied to a bill deposit machine (paper leaf input machine) 300. It is explanatory drawing which shows an example.
The banknote deposit machine 300 as a banknote handling device is a banknote corner fold using a banknote deposit machine main body (paper leaf input machine main body) 310 and a banknote corner fold correction mechanism 1 according to any one of the above embodiments. A partial correction device 350 is provided.
The bill depositing machine main body 310 has a housing 311 having a bill depositing port (paper leaf insertion port) 312 on the front side, a bill introducing path 315 arranged in the housing 311 and a branching path (banknote introduction route) 316. , 317, a banknote identification unit (paper leaf identification unit) 320 for determining the presence or absence of denomination, authenticity, and corner folds of banknotes introduced from the banknote deposit slot 312, and banknotes introduced by each branch path 316, 317. The banknote storage (paper leaf storage) 330, 340, which accepts each type of banknote, the banknote corner fold correction device 350, which is installed in each banknote storage 330, 340, the banknote introduction route 315, and the branch route. It is roughly provided with a transport drive mechanism including rollers, belts, motors and the like for transporting banknotes along 316 and 317, and control means 370 and the like for controlling these.
The bill corner folding portion correction device 350 is installed in the bill deposit safe 330 and 340 in the bill deposit machine main body 310.

The bill identification unit in a conventional deposit machine detects the presence or absence of a corner fold of a bill that has been deposited from the bill deposit opening, and has a large corner fold that exceeds a predetermined corner fold dimension reference value (for example, 15 mm). Was rejected by returning it to the banknote deposit slot. On the other hand, in the case of a banknote having a corner fold smaller than the above reference value, the banknote was directly transported to the banknote safe.
Therefore, in the conventional deposit machine, the bills stored in each bill deposit safe include bills that are determined to be normal, such as no corner folds by the bill identification unit, and bills that have small corner folds. Including. That is, a bill having a small corner fold is stored in the storage portion of the conventional deposit machine together with other normal bills. The small banknotes with corner folds contained in the stored banknotes had to be corrected by using a separate corner fold correction device or by hand.
On the other hand, in the present invention, the banknote identification unit 320 does not determine the presence or absence of the corner fold, or even if it determines, all the banknotes having other acceptance conditions including the banknote with the corner fold are uniformly selected. Introduce to each banknote deposit safe 330. Then, for all the introduced banknotes, the corner fold correction process 1 by the corner fold correction mechanism 1 constituting the bill corner fold correction device 350, that is, the lowering operation by the pressurizing member 60 is performed. Therefore, in the banknotes finally stored in the banknote safes 330 and 340, normal banknotes with the corner folds corrected are stored.
Therefore, it is possible to improve the deposit processing speed of banknotes as compared with the conventional deposit machine.

[Processing procedure by the bill handling device 300]
FIG. 16 is a flowchart showing a processing procedure by the bill handling device 300 including a bill corner fold straightening procedure by the corner fold straightening device 350.
When it is detected in step S21 that a banknote (paper leaf) has been deposited (inserted) from the banknote deposit port (paper leaf slot) 312 by a paper passing sensor (not shown), the banknote identification unit 320 deposits the banknote in step S22. Whether or not to accept the banknotes deposited from the mouth 312 (authenticity, denomination, etc.) is determined, and if it is acceptable, any banknote is inserted into the denomination via the banknote introduction route 315, each branch route 316, 317. It is transported to a safe (paper leaf storage) 330, 340 and introduced into the corner fold correction mechanism 1 (step S23). At this time, the bill identification unit 320 does not determine the presence or absence of the corner-folded portion, and even the bill having the corner-folded portion is conveyed to the banknote safe. If it is unacceptable, it is returned to the bill deposit slot 312 (S24).

In each corner fold correction mechanism 1 in the banknote safe 330 and 340, each end piece of the paper leaf is inserted into each of the guide vacant spaces 13 and 43, and each end piece is supported by each guide vacant space. and step S25, each of the end pieces 101a pressing member 60 pushes the surface middle part of the paper, by moving 101b and along the guide member 10, 4 0, each end piece along the guide member and Step S26 in which the corner folds 105 and 110 on the front and back of the paper sheet are sequentially corrected by the corner fold correction portions 15 and 45 in the process of moving, and the pressure member is pushed to the end position and each end piece is moved to the end position. Step S27, in which the pressure member is separated from the guide member and then returned to the initial position, is performed.
In step S28, the presence or absence of a succeeding bill is checked, and if there is a succeeding bill, the process returns to step S22 and the same routine as above is repeated, and if there is no succeeding bill, the process ends.

In this way, the corner fold correction process is performed by the corner fold correction mechanism 1 for all the introduced banknotes. Therefore, in the banknotes finally stored in the banknote safes 330 and 340, normal banknotes with the corner folds corrected are stored.
Therefore, it is possible to improve the deposit processing speed of banknotes as compared with the conventional deposit machine.
In addition, since the corner folds are corrected and aggregated / accumulated in the pre-process of the banknote counting / sorting / sorting work, the efficiency of the banknote counting / sorting / sorting work in the post-process can be inevitably improved.

<Summary of composition, action, and effect of the present invention>
The first corner-folding correction mechanism 1 of the paper leaf according to the present invention is arranged in parallel with a space S shorter than the longitudinal length of the paper leaf 100, and is a guide space 13 for inserting the paper leaf. Two guide members 10 and 40 having 43 at opposite positions and a movement path P intersecting (orthogonal) with the surface of the paper leaf supported by the guide vacant spaces at both ends 101a and 101b to move forward and backward in the space. A pressure member 60 is provided, and in a state where both end pieces of the paper leaf are supported by two guide vacant spaces, the pressure member pushes the middle portion of the surface of the paper leaf and the both end pieces of the paper leaf are pushed from each guide vacant space. Each of the guide members 10 and 40 is provided with a structure for separating the guide members 10 and 40, and each of the guide members 10 and 40 is provided with corner fold straightening portions 15 and 45 for correcting the corner folds of the paper leaf in the process of separating both ends of the paper leaf from each guide space. It is characterized by that.
In the counting, sorting and sorting of paper sheets such as banknotes, automation is desired in order to eliminate the complexity of the work, improve efficiency, and improve security such as fraud prevention. Paper leaf sorters that support counting, sorting, and sorting reject square-folded paper leaves, 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.

In the present invention, both ends of a paper sheet having corner folds at least at the corners are suspended by guide spaces 13 and 43, and the center of the paper leaf is pushed by a pressure member to the outside of the guide space. in the process of lowering along the guide member while bending the paper ends pieces which protrudes, after standing upward folded corner portion 105 by the paddle folded corner portion correcting portion 17, 47 provided on the guide member, folded Unfold and flatten. Then, after the paper ends pieces which have been further lowered along the guide member which have passed through the guide cavity, enters inside the guide member moves along the inner surface of the guide member, downwardly folded corner portion 110 receives correction when passing through the corner bending portion correction portions 27 and 57. After the front and back corner folds have been straightened by each corner fold correction part, that is, after both ends of the paper leaf have passed through each guide space and entered the inside of each guide member, each end piece is the inner surface of each guide member. It moves along and finally separates from the lower part of the guide member and unfolds. Straightening folded corner portions of the front and rear surfaces each folded corner portions correction unit comprises the steps of each end piece is lowered along the guide member which is located above the guide cavity, the end edges each guide empty each end piece Each is carried out in the process of passing through the place. That is, the corner folds on the front and back surfaces can be corrected at once by the one-time lowering operation of the pressure member, and the work of increasing the number of steps such as reciprocating the paper sheet can be avoided.

The guide vacant spaces 13 and 43 not only serve as support parts when suspending paper sheets, but also correct corner folds 110 bent toward the back side at the lower end edge of the inner surface (inner peripheral surface) of each guide vacant space. Corner fold straightening edge 27s and 57s are provided for this purpose. Therefore, the configuration of the guide member can be simplified without increasing the number of parts.
The guide spaces 13 and 43 do not have to be closed spaces, and may be open spaces having a notch in a part. In this case, the paper leaf can be inserted into the guide vacant space from the notch, and the degree of freedom in layout at the time of design is increased.
The fact that the guide vacant spaces 13 and 43 for inserting paper sheets are provided at opposite positions means that the guide members 10 and 40 are arranged at substantially the same height position and lateral position, thereby. It is possible to support the paper sheet in a posture orthogonal to each guide member surface. Even if the positions of the guide vacant spaces 13 and 43 are slightly displaced, they are arranged at opposite positions as long as the suspension of the paper sheets is not hindered. That is, in a strict sense, it is not necessary that guide vacant spaces having the same shape are arranged at the same height and in the lateral position.
Further, according to the corner fold correction, accumulation, and storage work according to the present invention, it is possible to eliminate all the front and back corner folds formed at any corner of the paper sheet by one operation. For this reason, complicated transportation such as switchback transportation of paper sheets becomes unnecessary, and it is possible to reduce the transportation space and the number of members. In addition, since the corner folds can be eliminated by moving the paper leaf the minimum necessary distance, the risk of paper leaf clogging, skewing, etc. can be eliminated.

In the second corner fold straightening mechanism 1 of the paper leaf according to the present invention, the corner fold straightening portions 15 and 45 are the first corner fold straightening portions for correcting the corner fold portion 105 on the surface side of the paper leaf. (First corner fold straightening edge) 17, 47 and second corner fold straightening part (second corner fold straightening edge) 27, which straightens the corner fold 110 on the back side of the paper leaf. It is characterized by having 57 and.
Since the first corner fold straightening portions 17 and 47 and the second corner fold straightening portions 27 and 57 are provided on the guide members 10 and 40, respectively, a single operation of pushing the paper leaf with the pressurizing member is performed. It is possible to correct the corner folds on both the front and back sides of both ends of the paper sheet at once.

In the third corner fold straightening mechanism 1 of the paper leaf according to the present invention, the first corner fold straightening portions 17 and 47 are provided on the tip edge of each guide member, and the second corner fold straightening portion 27, The 57 is provided at the lower end edge of the inner surface (inner peripheral edge) of each guide vacant space.
According to this, with a simple and compact structure that does not increase the number of parts or complicate the structure, the paper leaf can be suspended in the initial insertion posture, and the front and back corners at the corners of the paper leaf can be broken. It is possible to realize a mechanism for correcting the parts at once.

In the fourth corner fold correction mechanism 1 of the paper leaf according to the present invention, the first corner fold correction portions 17 and 47 are located closer to the inside than the second corner fold correction portions 27 and 57, respectively. It is characterized by being arranged.
The corner-folded portion straightening portions 17 and 47 and the corner-folded portion straightening portions 27 and 57 may be displaced in and out with respect to the space S. That is, by arranging the second corner fold straightening portions 27 and 57 on the outside of the first corner fold straightening portions 17 and 47 located above (staggered arrangement), the suspension paper leaf is formed by the pressurizing member. It is possible to quickly and efficiently deform the end pieces 101a and 101b upward when the central portion is pushed in, and prevent skewing due to irregular misalignment of both end pieces in each guide space.

In the fifth aspect of the paper leaf corner fold correction mechanism 1 according to the present invention, each of the guide members 10 and 40 has the first guide pieces 11 and 41 located at the upper inside and the guide vacant spaces 13 and 43 in between. The second guide pieces 12 and 42, which are located at the lower outer side of each of the first guide pieces, are provided, respectively, and the first corner fold straightening portions 17 and 47 are provided at the tip of the first guide piece. However, the tip of the second guide piece is characterized by having the second corner-folded portion straightening portions 27, 57.
At the lower end edges 11a and 41a of the first guide pieces 11 and 41 corresponding to the upper end edges of the inner surfaces (inner peripheral edges) of the guide vacant spaces 13 and 43 and at the lower end edges of the inner surfaces (inner peripheral edges) of the guide vacant spaces 13 and 43. Since the inner and outer positions of the corresponding second guide pieces 12 and 42 are deviated from the upper end edges, the movement of the paper leaf end pieces being deformed upward by pushing the pressure member becomes smooth, and each paper leaf after standing up. The upper surface (inner side surface) of the end piece easily approaches the outer surface of the first guide pieces 11 and 41. Therefore, the tip of each corner-folded portion straightening portion smoothly enters between each corner-folded portion and the paper leaf main body, and the straightening work can be easily performed.

In the sixth corner-folded portion correction mechanism 1 of the paper leaf according to the present invention, the width dimension of each corner-folded portion-corrected portion (corrected edge) 17, 47, 27, 57 gradually decreases evenly to the left and right toward the tip. It is characterized by having a configuration.
The structure in which the width dimension gradually decreases evenly to the left and right toward the tip is a structure in which the width is tapered in a figure eight shape in front view and back view, and the corner folds of the paper leaf end pieces come into contact with each straightening part. Then, in the process of moving along each straightening portion, the corner bent portion can be expanded and flattened.

In the seventh corner-folded portion correction mechanism 1 of the paper leaf according to the present invention, the wall thickness of each corner-folded portion-corrected portion (corrected edge) 17, 47, 27, 57 gradually decreases toward the tip portion. It is characterized by.
In order for the corner fold correction edge to enter the gap between the paper leaf body and the triangular fold (corner fold) and spread the corner fold, the wall thickness gradually decreases toward the tip. It is advantageous to have a tapered structure.

The eighth aspect of the paper leaf corner bending correction mechanism according to the present invention is that a friction member for preventing slippage with the paper leaf is arranged on the bottom surface 61 of the pressure member in contact with the surface intermediate portion of the paper leaf. It is a feature.
A friction member 63 made of a material having a large frictional resistance is arranged on the bottom surface 61 of the pressure member so as not to cause slippage when the surface of the paper sheet is pressed. As a result, it is possible to prevent the paper leaf from being pushed in poorly.

In the method for correcting the corner folds of the paper leaf according to the ninth aspect of the present invention, each end piece of the paper leaf is inserted into each guide space, and each end piece is supported by each guide space. the method comprising the state, a step of pressing member moves along each end piece to the guide member pushes the surface middle part of the paper, each in the course of each end piece is moved along the guide member It is provided with a step of correcting each corner fold of the paper leaf by the corner fold correction part and a step of moving the pressure member to the end position of pushing and separating each end piece from each guide member. It is a feature.
Each end piece of the paper is the folded corner portion correction portion positioned upward in the course of moving along the guide member is corrected upward folded corner portion, followed by a folded corner correction unit positioned below the downward The broken corner is corrected. Immediately after the downward corner fold is corrected, the edge of each end piece enters the guide space and moves into the space.
In the pre-process of setting paper sheets in a paper leaf handling device such as a vending machine that counts, sorts, and sorts paper sheets, the corner folds are corrected by correcting the corner folds according to the method of the present invention. Since it is aggregated and integrated, it is inevitably possible to improve the efficiency of paper leaf counting, sorting, and sorting operations in the post-process.

The tenth paper leaf handling device 250 according to the present invention has a paper feed unit 201 that separates and feeds out the loaded paper sheets one by one, and a corner-folded portion of the paper leaf that is fed out from the paper feed unit. A paper leaf organizer 200 provided with a paper leaf identification unit 205 for determining, and a corner fold correction device that accepts a paper sheet determined by the paper leaf identification unit to have a corner fold and corrects the corner fold. The corner fold correction device 260 includes a corner fold paper leaf loading portion 261 for loading a paper leaf having a corner fold portion, a corner fold portion correction mechanism 1 for the paper leaf, and a corner fold of the paper leaf. It is characterized by including a storage portion 262 for accommodating paper sheets that have been straightened by the partial correction mechanism 1.
The paper leaves that have been straightened at the corners and accumulated in the storage section 262 are reset to the paper feed section 201 of the paper leaf organizer, and are stored in the storage section 220 through a predetermined procedure.
In this way, the corner folds are corrected and aggregated / accumulated in the pre-process of the paper leaf counting / sorting / sorting work, so it is inevitable to improve the efficiency of the paper leaf counting / sorting / sorting work in the post-process. Can be done.
