Description

TECHNICAL FIELD The present invention relates to a paper sheet processing apparatus, and in particular, it is possible to reverse the first surface and the second surface of a paper sheet during the transportation of the paper sheet. The present invention relates to a sheet processing apparatus having a sheet reversing function.

[Conventional technology]

As a conventional sheet processing apparatus having this type of sheet reversing function, for example, there is one disclosed in Japanese Utility Model Publication No. 55-120639. However, no consideration has been given to the surface shape of the surface of the sandwiching roller pair on the side of the peripheral end surface for sending out the reversed paper sheet to the next conveying path.

[Problems to be solved by the invention]

When the shape of the end surface of the sandwiching roller pair that has sent the paper sheet after the conveyance direction is reversed to the third conveying path is not taken into consideration, the leading edge of the paper sheet at the time of reversal collides with the surface of the sandwiching roller. As a result, there are problems that the front edge portion of the paper sheet after the reversal is damaged or that the reversing operation is unstable and the reversal time is delayed. This problem is likely to occur especially when the skewed paper sheets are reversed.

An object of the present invention is to prevent damage and breakage that occur at the leading edge of a sheet after reversing, stabilize the reversing operation, and prevent a reversing time delay.

[Means for solving problems]

In a paper sheet processing apparatus having a reversing mechanism for selectively reversing the first surface and the second surface of the paper sheet based on a signal from the discriminating unit in the middle of the conveyance path for conveying the paper sheet, A first conveyance path for conveying the paper sheets from the discrimination section, and the first conveyance path.
Is provided in the middle of the conveying path of the sheet, and the paper sheet is placed in the first face-oriented paper sheet and the second face-oriented paper sheet based on the discrimination result of the first surface and the second surface of the paper sheet by the discrimination unit. A sorting unit that sorts the sheets into sheets, a second transport path that transports one of the paper sheets sorted by the sorting unit, and a second transport path that is connected to the second transport path And a third conveyance path, and between the second conveyance path and the third conveyance path, paper sheet conveyance direction reversing means for reversing the conveyance direction of the paper sheet, and the paper sheet. A paper sheet pushing member guiding means for guiding the papers from the second conveying path to the reversing means, and guiding the papers from the reversing means to the third conveying path, and narrowing the papers guided by the reversing means. A nipping roller pair for holding and delivering to the third conveying path is provided, and one of the nipping roller pair is coaxial with the paper sheet pushing member-equipped guiding means. For example, it was achieved by forming so that its diameter gets closer to the end face surface of the axial end face side of the roller with the paper leaf pushing member with guide means coaxially is gradually reduced.

[Action]

When the paper sheet after the reversal of the conveyance direction is sent to the third conveyance path, the paper sheet pressing member for guiding the paper sheet to the third conveyance path causes the front edge ventral side of the paper sheet to move. Similar to being pressed against one of the holding rollers, the leading edge of the paper sheet collides with the other of the holding roller pairs, that is, the surface of the holding roller on the pressing member side. At this time, since the peripheral end surface side surface of the holding roller on the pressing member side is formed so that the diameter thereof gradually decreases as it goes outward, a breakage occurs at the front edge of the sheet after reversal. There is nothing to do, and scratches and breaks do not occur especially on skewed paper sheets. As a result, the reversing operation of the paper sheets is stabilized, and the reversal time delay is less likely to occur.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

In the following description, the first side, which is the front-sided paper sheet, refers to a paper sheet that does not need to be turned upside down.
The face-down paper sheet, which is the surface of, is a paper sheet that needs to be turned upside down.

FIG. 1 is a schematic sectional view of this embodiment, and FIG. 2 is a first A- line.
FIG. In FIG. 1, a paper sheet processing apparatus includes a conveyance path structure including a plurality of conveyance belts and a plurality of pulleys, a sorting unit that switches the conveyance path according to front-faced paper sheets and back-faced paper sheets, and paper sheets. Reversing means for reversing, the paper sheet pressing member-provided guide means provided between the conveying path and the reversing part, and the paper sheet guided by the guiding means is sandwiched to the third conveying path. It is equipped with a pair of gripping rollers for sending out.

The above-described transport path structure includes the transport belts 1, 2, 3, 4, the merging guide 5 and the reversing guide 20. This conveyor belt 1
Is on the conveyor belt 2 engaged with the pulleys 7,9,19,8,18, on the conveyor belt 3 engaged with the pulleys 10,11,12 and the pulleys 70,1.
7 is engaged on the conveyor belt 4 that engages with the pulleys 6, 14, 15, 1

Further, the conveyor belt 1, a portion of the conveyor belt 2 and the conveyor belt 3 and the merging guide 5 make a first conveyor path, a portion of the conveyor belt 2, a gate 21 and a pulley 19 make a second conveyor path, a reverse guide. 20 and the merging guide 5 respectively form a third conveyance path. The aforementioned partitioning means is composed of a gate 21 which is supported so as to be rotatable around the shaft of the aforementioned pulley 10. The gate 21 has a guide surface 21a on its tip side and rotates about the axis of the pulley 10 to a solid line position or a two-dot chain line position shown in the figure. Then, when it is rotated to the position shown by the solid line, the above-described first transport path is communicated with the second transport path and the third transport path.

The above-mentioned reversing means is arranged between the second conveying path and the third conveying path, and in order to float the reverse-facing paper sheet for reversing from the above-mentioned second conveying path and smoothly carry it in and out. The loading guide frame 22, the unloading guide frame 23, and the entry stop member 24 provided between the guide frames 22 and 23.

Further, the above-mentioned guide means includes a guide roller 25 arranged on the shaft of the pulley 19. The pulley 19 is formed such that its peripheral end surface side surface gradually decreases in diameter as it goes outward, and in this example, the peripheral end surface side surface is formed in a substantially arc shape. . As a result, there are no corners on the surface of the pulley 19. Also, this guide roller 25
Flexible projections 26 are provided on the outer peripheral surface of the sheet as one or a plurality of radially pressing members. The outer diameter of the protrusion 26 is configured to be slightly larger than the outer diameter of the pulley 19. The positions where the entrance stop member 24 and the guide roller 25 are arranged are set so as to be substantially equal to the length in the conveyance direction of the face-down paper sheet for reversing the distance between them.

Then, the above-mentioned guide roller 25 has the above-mentioned guide frames 22 and 23.
When a paper sheet that faces down for turning inside is brought into contact with the paper sheet and is provided at a position where the paper sheet is pressed against the traveling surface of the second conveying path, curling or folding is performed. Gently insert paper sheets into the guide frame.
Further, the guide roller 25 contacts the trailing edge of the paper sheet colliding with the entry stop member 24 provided in the guide frame, and the trailing edge of the paper sheet is moved from the second transport path side to the third transport path side. By arranging it at a position where it is moved to and pressed against the reversing guide 20 of the third conveyance path, the curled and folded paper sheets are smoothly conveyed into the third conveyance path. Here, 30 is a sandwiching roller provided so as to face the pulley 19 and forms a sandwiching roller pair with the pulley 19.

In addition, a gate which is a sorting means provided in the middle of the first transport path.
The conveyance time from 21 to the roller 12 via the first conveyance path, and the sheet requiring reversing the front and back is sorted by the gate 21 described above, and then the reversing operation is performed via the second conveyance path. The transport path length and the transport speed of each transport path are set so that the transport time to reach the rear roller 12 becomes equal.

Next, the transport operation of this embodiment will be described.

The paper sheets are held by the conveyor belts 1 and 2 and conveyed from the arrow 27 to the gate 21. Here, in the case of face-up paper sheets, the gate 21 is rotated clockwise about the axis of the roller 10 by a drive source (not shown) to a position indicated by a chain double-dashed line in FIG. Therefore, the face-up paper sheets are conveyed to the merging guide 5 by holding the conveying belts 1 and 3.
It can be held by the conveyor belts 1 and 4 and carried out downward (in the direction of arrow 28), and can be conveyed, for example, in the direction of a sheet storage unit (not shown).

Next, in the case of the paper sheet facing down, the gate 21 is rotated counterclockwise about the shaft of the pulley 10 by the drive source (not shown) to the position shown by the solid line in FIG. Therefore, the back-faced paper sheet 29 is separated from the front-faced paper sheet by the gate 21 and conveyed along the conveyor belt 2 as shown in FIG. Then, due to the interaction of the carry-out guide frame 23 and the guide roller 25, the paper is carried into the reversing unit for reversing the sheets. Here, 29a indicates the front end face of the face-down paper sheet 29.

In the reversing unit, the paper sheet is reversed by the following operation. This reversing operation will be described with reference to FIGS.

FIG. 3 shows the back-sided paper sheets 29 when entering the space constituted by the carry-in guide frame 22 and the carry-out guide frame 23.
29 shows the state of the front end face 29a. The protrusion 26 provided on the outer peripheral surface of the guide roller 25 is larger than the outer peripheral diameter of the pulley 19.
Since the outer peripheral diameter of the sheet is larger, the face-down paper sheets 29 are pressed against the conveyor belt 2 by the forced deformation force. The deformation amount at this time is regulated by the carry-in guide frame 22, and the front end surface 29a of the back-faced paper sheet 29 is forcibly deformed, so that the back-faced paper sheet 29 has an apparently large rigidity. Then, it smoothly advances into the guide frames 22 and 23, and finally collides with the entry stop member 24 to stop. Next, as shown in FIG. 4, the backside paper sheets 29 are arranged such that the distance between the outer peripheral surface of the guide roller 25 and the entry stop member 24 is the conveyance backside paper sheets.
Since the length of the paper 29 is substantially equal to or smaller than the length of the conveying direction of 29, the rear-faced paper sheet 29 has a rear end surface 29b with rotation of the protrusion 26 provided on the outer peripheral surface of the guide roller 25. It is pressed against the holding roller 30 and the reversing guide 20. At this time, the rear end surface 29b of the face-down paper sheet 29 is in the state shown in FIG. That is, the rear end surface 29b of the face-down paper sheet 29 receives a forced deformation force and is pressed against the sandwiching roller 30 and the reversing guide 20. The amount of deformation at this time is currently controlled by the reversing guide 20, and since the rear end surface 29b of the back-faced paper sheet 29 is forcibly deformed, the rigidity of the back-faced paper sheet 29 is apparently increased, Of the rear end surface 29b of the face-down paper sheet 29, a portion 29b 'of the guide roller 25 that does not come into contact with the protrusion 26 is in a state as shown in FIGS. 4 and 5, and forms a pair with the sandwiching roller 30. Collide with the holding roller 19. However, the peripheral end surface side surface of the roller 19 is formed in a substantially circular arc shape, and since there are no corners on the surface, the rear end surface of the back-faced paper sheet 29 is
The 29b 'can smoothly enter the third conveying path constituted by the reversing guide 20 and the merging guide 5 without causing damage such as breakage. After that, it is conveyed along the conveyor belts 1 and 4 shown in FIG. 1, and is conveyed downward along the arrow 28.

Therefore, the paper sheets held by the conveyor belts 1 and 4 and conveyed downward are all conveyed in the same direction as that of the above-mentioned face-up paper sheets. In addition, by the gate 21, the conveyor belt 1,
The conveyance time from the gripping part of 3 to the gripping part of the conveyor belts 1 and 4, and the gate 21, the conveyor belt 1 and the roller 19
The length and speed of each transport path are set so that the transport time including the reversal time until the transport belts 1 and 4 reach the gripping portion after the reversing operation of the transport paper sheets via the gripping portion of Is set. Therefore, only the face-down paper sheets should be gate 21
And then reverse the front and back in the above-mentioned transport path, transport belt 1,
When the sheet is conveyed to the post-processing section according to 4, there is no variation in the interval with the front-faced sheets, and there is no inconvenience in processing.

Next, FIG. 6 shows another type of protrusion 26 arranged on the outer peripheral surface of the guide roller 25 in the above embodiment, but the operation and effect of the present invention are exactly the same.

In this way, the paper sheet processing apparatus of the present invention can convert all the mixed paper sheets on the front and back sides into paper sheets on which the front and back sides are aligned. Therefore, for example, in the automatic teller machine shown in FIG. Used by incorporating. The automatic teller machine handles banknotes as paper sheets.

A separating device 34 for taking in the deposited bills 33 is provided on one side of the deposit / withdrawal port 32, and an extruding plate 36 for pushing out the dispensed bills 35 to the deposit / withdrawal port 32 is provided on the other side. A bill discriminating unit 37 is provided in the central portion of the main body 31, and discriminates the authenticity of bills 33, 35 to be taken in or paid out, the front and back of denomination, the number of bills, and the like. In the rear part of the main body 31, the front and back reversing part 38 shown in FIG. 1 is provided. Below that, a temporary stack part having an impeller 39 for temporarily storing the taken-in bills 33 is provided. A stack portion including an impeller 40 is provided, and a lower portion of a main body 31 is provided with a first impeller 41 and a second impeller 42 for stacking bills for bill recycling. Each banknote group stacked by each impeller 39, 41, 42
43, 44, and 45 are stored in a safe 46, a first denomination box 47, and a second denomination box 48, respectively. Further, between the cashbox 46 and the second denomination box 48, a reject box 49 for collecting unidentifiable banknotes is arranged. Separation devices 50, 51, 52 are provided above the safe 46 and denomination boxes 47, 48, respectively, to separate and take out the respective bills 43, 44, 45 one by one. The above-mentioned respective parts are connected by a conveying means, and sorting gates 53 to 59 are provided at a branch portion in the conveying means.

In this automatic teller machine, the customer can
The banknote 33 inserted for deposit in is generally taken out from the wallet, so the front and back are in a mixed state.
In the above, only those which are judged to be face down are turned upside down by transporting the face upside down part 38, and all are turned upside down and temporarily stored in the upper part of the safe 46 by the temporary stack part equipped with the impeller 39. The first denomination box 47, the second denomination box 48, and those not used for withdrawal are stored in the reject box 49, respectively. In addition, the first denomination box 4 according to the customer's withdrawal request
