Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention is a block for paper sheets in a banknote handling machine or the like that supports banknotes, cards and other paper sheets in a bundle in an upright state and transfers them to a predetermined position. Concerning a carrier device.

[Prior Art] Generally, this type of device is an arm-shaped front support and a rear support that clamp a sheet bundle from the front and back to a predetermined position and transfer it to the next processing step. Returns to the original home position and transfers the next sheet bundle again.

[Problems to be solved] In this block transfer device, a rear support having a normal structure is connected to a drive device to move forward, and a braking means such as a spring is connected to the front support to connect a sheet bundle between both supports. If the structure is adopted in which it is sandwiched in the upright position and pushed forward to the target position by the rear support and handed over to the next process, the following problems occur in the front support structure.

First of all, when sandwiching a bundle of paper sheets, the paper sheets in the front row are caught on the front support and may be bent or lose their posture. In particular, if one tries to inject and stack the sheets one by one between the supports, the first sheet is caught by the front support and cannot be collected properly.

Further, also when the sheet bundle is delivered to the next process at the target position, there arises a problem that when the front support is separated from the sheet bundle, the sheets in the front row are torn off or bent together.

However, in the conventional device, the arm-shaped front support is prepared at the transporting target position and the stopper for receiving the front side of the paper sheet receives the front side of the sheet bundle and at the same time pulls out the front support. Since it is a member, when it was pulled out, the paper sheets in the front row were often pulled out together and the alignment was disturbed frequently.

Similarly, when sandwiching paper sheets, the frontmost paper sheets are often bent or disturbed in posture, and it is a fatal defect that the paper sheets are removed or damaged especially in a device handling bills and the like. Not only that, but even if the alignment state is disturbed, a mistake such as paper jam (jam) may occur in the next process.

[Means for Solving Problems] The present invention has been made to solve the above-mentioned conventional problems, and as a means for solving the problems, a paper sheet block conveying device of the present invention is a guide for supporting the bottom surface of a paper sheet bundle. And a front support that supports the front of the bundle of paper and a rear support that supports the back of the bundle of paper in a standing state, and the forward movement of the front support and the rear support moves the bundle of paper. In a paper sheet block transporting device for transporting a paper sheet along a guide, the front support is movably attached to the machine frame along with the guide, and the front support is placed in an operating position for engagement with the paper sheet bundle. The front support is configured to be movable between the disengagement positions, and the engaging portion of the front support with the sheet bundle is formed of a rollable rotating body.

[Operation] When the front support supporting the front surface of the sheet bundle moves upward or downward to capture or release the sheet bundle, it is pressed from the rear by a rear support or the like so as not to tip the sheet bundle. Even if it does, since the surface of the bill is slid and captured and released by the rolling body provided on the front support, the posture of the bill is not disturbed, and the bill is not bent or damaged.

[Embodiment] As an embodiment of the present invention, an automatic bill handling apparatus (Automated Te
ller Machine; hereinafter referred to as ATM).

FIG. 1 is an overall explanatory view, and the illustrated one is composed of a customer service section 3, a discrimination section 5, a front and back aligning section 7, a recycling stacker 9, 11, a forget-to-take eject box 13, and a scrutiny replenishment safe box 15. It is a so-called recycle type ATM that can pay (refund) banknotes and accept (deposit) banknotes and circulate and pay the deposited banknotes.

Each of the above-mentioned components is connected so as to circulate banknotes through the transportation route as shown in the figure. Explaining each route, the payment system (payback of banknotes) is such that the depositor inserts the card at the customer service port 4 and pays out the withdrawal amount. When instructed, a central processing unit (not shown), which is separately configured, accepts the instruction and instructs the illustrated ATM to pay. In response to this instruction signal, the bills P are separated and fed out by the separating means 8 and 10 from the recycling stackers 9 and 11 prepared for each denomination, and are guided to the discrimination section 5 from the routes 51 and 53 through the route 19. The discrimination unit 5 counts the number of fed-out sheets, discriminates the authenticity of bills, discriminates unfit bills, and discriminates multiple feeds (double feed), and multi-feeds, undelivered bills, and counterfeit bills pass through routes 21, 35, 57. It is stored in the reject box 13 from 59. The ticket is the route
After 21,23,31, the bills are accommodated in the aligning section 6, and when all the bills to be paid are prepared, they are block-transported to the customer service port 4 and the depositor takes them out and ends the transaction.

Next, in the deposit system that accepts banknotes, when the depositor sets the banknotes in a bundle in the customer service port 4, the capturing and separating section 41 separates the banknotes one by one and sends the separated banknotes to the path 17, and the path 19 to the discrimination section 5. After being sent, the discrimination section 5 discriminates the authenticity, the unfit banknote, and the large number (double feed), and the improper banknotes are sent from the path 31 to the aligning section 6 via the paths 21 and 23 and temporarily stocked, and then from the customer service port 4. It is supposed to be returned to the depositor.

In the case of a genuine ticket, the discrimination unit 5 discriminates the denomination, counts the number of denominations, and discriminates between the front and the back, and guides the route from the route 25 to the route 27 to the route 27 via the routes 21 and 23. They are stocked in the front and back aligning section 7.

Then, the banknotes whose front and back are aligned by the separating means 71 are separated one by one from the front and back aligning section 7 and sent to the discrimination section 5 again through the feeding paths 33 and 19, and the discrimination is performed in the same manner as described above and the path 21 to the path 35.
It is adapted to be accommodated in the recycling stackers 9 and 11 from the feeding routes 43 and 45 and the types of money from the routes 45 and 49.

Thus, the banknotes are to be deposited and withdrawn between the customer service port 4 and the recycling stackers 9 and 11, but when the banknotes are replenished or taken out from the recycling stackers 9 and 11, this stacker is used. In the case of directly putting in and out of 9,11, of course, it is necessary to check the number of replenished or taken out, of course, it is inevitable to perform troublesome and precise work such as checking for bad notes, front and back, checking denomination To be done.

Therefore, as shown in the figure, a safe 15 is provided separately from the recycle stackers 9 and 11. When banknotes are put into the safe 15, they are separated one by one by the separating means 16 and sent to the route 55 and sent from the route 19 to the discrimination section 5. If the bill is unfit, it is sent from the routes 21 and 35 to the route 59 and stored in the reject box 13.

Then, the normal tickets are sent from the routes 21, 23, 25 to the front-side tickets to the route 27 and the back-side tickets to the route 29, the front and back aligning section 7 aligns the front and back sides, and the discrimination section 5 counts the denominations again, and the routes 21, 35, Stored in recycling stackers 9 and 11 for each denomination from routes 47 and 49 via 43 and 45.

When collecting banknotes from the recycle stackers 9 and 11 to the safe 15, the banknotes separated from the stackers 9 and 11 one by one and fed out are sent from the paths 51 and 53 to the path 19 and counted by the discrimination section 5 by denomination. It is designed to be sent from the routes 21, 35 to the routes 57, 61 and stored in the safe 15.

Each of the separating means described above accommodates a banknote in an upright state and sequentially pushes out the back surface of the banknote with a kick roller provided on the front surface and sends the banknote to a roller pair which is pressed and contacted, and this roller pair is regarded as a stationary roller. It is shown that the rollers that rotate in the paper feeding direction are separated one by one.

The configuration of each unit will be briefly described below.

The customer service section 3 is composed of a box 60 for depositing and withdrawing banknotes, its opening / closing lid (shutter 43), a take-in separation section 41, and an aligning section 6. When the banknotes are put into the box in a bundle, It moves to the taking-in / separating section 41, and the separating section 41 separates the sheets one by one and sends them to the discriminating section 5. The bills fed from the recycle stackers 9 and 11 are accumulated in the alignment unit 6 through the discrimination unit 5. The banknotes accumulated in the arranging section 6 are lifted up like an elevator and shifted to the box 60 so that the depositor can take them out from the customer service port 4.

The front and back aligning unit 7 is a path for the banknotes that are discriminated between the front and back in the discrimination unit 5.
At 25, it is branched into a frontward path 27 and a rearward path 29, and is fed to a box-shaped stacking section 72 by paper discharge rollers 73 and 74. When all the one-time transaction tickets are accumulated, the separating means 71 separates and delivers them.

The discriminating section 5 discriminates the authenticity of bills, front and back, denomination, unfit note, and double feed (overlapping of multiple sheets), at the same time counting the number of denominations and transmitting information to the central processing unit. Signal control information.

Recycle stackers 9 and 11 are prepared for each denomination. The one shown in the figure is a 1000 yen ticket and a 10000 yen ticket as a denomination, and a 5000 yen ticket is accepted as a deposit ticket, but if it is discriminated by the discrimination section 5, it will be a direct safe 15 To house. Therefore recycle stacker
Two of the same structures 9 and 11 are prepared, and feeding and separating means 8 and 10 are provided at one end of a box-shaped storage frame for storing banknotes.
However, the other end is provided with intake means 65, 66, and separation means 8, 1
Backup means 67, 68 for pressing the banknotes to the 0 side and support means 69, 70 for holding the banknotes on the take-in means 65, 66 side are provided, and the banknotes for payment and the banknotes for receipt of receipt are provided in this recycling stacker. The bills are stored and managed separately for right and left, and when the payer-side bills (stock on the left side in FIG. 1) are lost, the bills are transferred from the deposit-side bills (stock on the right side in FIG. 1). Therefore, when a mistake occurs due to a mechanical trouble or the like, the recycling stacker is checked so that the bill accepted immediately before that is identified.

The forget-to-take reject box 13 stores the banknote identified by the discriminating unit 15 as an unfit banknote, and at the same time detects a banknote forgotten by the depositor in the customer service port 4 and returns it to the reject box 13 via the discriminating unit 5. And this box is designed to be stored separately for unfit notes and forgotten notes.

The cashbox 15 carries out the above-mentioned functions, that is, scrutiny at the time of replenishing and collecting banknotes (counting amount, front and back arrangement, finding unfit banknotes, sorting denominations), and at the same time stores the 5000-yen banknotes removed from the banknotes to be paid. Furthermore, when the banknotes to be paid to the recycling stackers 9 and 11 are insufficient, they are automatically replenished, and when the recycling stackers 9 and 11 are filled with deposit banknotes, they are stored in this safe as overflow stackers. ing. Further, this safe 13 also stores replenishment bills in the left stock and the collected bills in the right stock as in the recycling stacker.

The case where the present invention is applied to such an apparatus will be described. In the illustrated embodiment, the recycling stacker 9 (the stacker 11 has the same structure and therefore the description thereof is omitted) has the right end thereof stocked with deposits and supplementary banknotes. The banknotes for withdrawal are stocked at the left end, and when the withdrawal side is insufficient, the banknotes are block-conveyed from the right stock and replenished.

As shown in FIG. 2, this recycle stacker 9 has a box-shaped storage frame 100 for storing banknotes in an upright position, with an outlet 101 provided at the front end and an outlet 102 provided at the rear end.
1, the separating means 8 is a kick roller 103, a paper feeding roller 104,
The kick roller 103 prepared by the separating roller 105 presses against the leading bill and pushes it toward the outlet 101 side, and the paper feeding roller 104
And the separation roller 105 are pressed against each other, the paper feed roller 104 is rotated to the right in the figure, and the separation roller 105 is stationary to prevent the second and subsequent banknotes from flowing out and separate them one by one. The separated banknotes are pressed against the feed roller 104 and applied in the same direction as the pinch roller 1
It will be pulled out at 06.

At the rear end side inlet 102, an intake roller composed of an impeller 107
An endless belt 109b is provided for the banknotes from the aforementioned path 47 provided with 65.
Each is arranged so as to be handed over to the impeller 107.

The impeller 107 is composed of a plurality of commonly known flexible blades that are radially arranged in a spiral shape, and moves while holding a banknote between the blades and ejects it at a predetermined position at the same time. The next blade sends out the bill.

On the outlet 101 side, the banknote bundle is supported by being sandwiched between the kick roller 103 and a backup plate 108 that comes into pressure contact with the rear surface thereof, and on the inlet 102 side, the front surface facing the outlet 101 is a front support 109 (the aforementioned support). The rear surface is supported by a locking stopper 110 by means) and stored separately. Therefore, the banknotes stored on the inflow port 102 side are block-transported to the outflow port 101 side so that the banknotes are sandwiched between the rear support 111 and the front support 109 to replenish the banknotes to be paid. Although it is configured to be movable left and right, the structure of this block transfer will be described in detail below.

(Structure of Backup Plate) As shown in FIG. 2, a backup plate 108 having a shape suitable for pressing and supporting a banknote bundle in an upright state from the back is fitted and supported by a shaft-shaped stem 112 as shown in FIG. It is movable left and right along a bottom guide plate 120 that forms a storage frame of. The backup plate 108 is constantly urged by a spring 121 to press the bill against the kick roller 103 on the outlet 101 side, and the inlet 10 of the engaging claw 123 provided on the timing belt 122 connected to the motor M.
The backup plate 108 is engaged so as to move simultaneously against the biasing spring 121 by traveling in two directions.

The engaging claw 123 fixed to the timing belt 122 is the third
At the standby position at the left end of the figure, the bill is pushed away from the backup plate 108 only in the range of the storage area l ₁ for bills for dispensing, by the action of the biasing spring 121. The backup plate 108 is advanced by a biasing spring 121 in an upright state to back the bill in a range of regions illustrated l _1, but retracted by a timing belt 122, the lower side of the bottom guide plate when retracted beyond this area l ₁ I am hiding in.

That is, the backup plate 108 is rotatably supported on the block 123 slidably fitted to the shaft-shaped stem 112 around the shaft 124, and the fan-shaped gear 125 and the base end of the plate 108 supported on the block 123 are supported. Pinion fixed to
The rack 127 that meshes with 126 and meshes with the fan-shaped gear 125 is l ₁
It is fixedly provided on the frame at the position beyond the figure.

A spring 128 is provided between the block 123 and the plate 108 to constantly urge it in the upright direction. When the fan gear 125 meshes with the rack 127, it rotates to the right in FIG.
The pinion 126 meshed with this rotates counterclockwise and rotates the plate 108 counterclockwise against the spring 128 to lie down.

In this state, the rear surface 128 of the plate 108 is flush with the bottom guide plate 120 and serves as a guide for banknote block transfer, which will be described later.

(Structure of Front Support) The front support 109 for storing the deposited banknote at the right end in FIG. 1 has the structure shown in FIG.

The banknotes conveyed by the endless belt 115 from the above-mentioned path 47 are intruded and held between the rows of the impeller 107 and are sent until they abut the bottom guide 128 of the storage frame 100. The blade pushes this forward, but as the amount of stored banknotes increases, the front support 109 that supports the front row of banknotes also needs to gradually advance (advance), and at the same time transfer and shift the banknote bundle to the outlet 102 side. There is a need.

Therefore, the illustrated front support 109 is fitted and supported by a shaft-shaped stem 129 (Fig. 5) and is reciprocally movable in the left and right directions.
The front support 109 is composed of two arm-like members separated by a lower first front support 109a and an upper second front support 109b to support the upper and lower sides of the front side of the banknote stack. I am doing it.

The first and second front supports 109a, 109b have their base end portions pivotally supported by a carriage 130 by a shaft 131, hold the front and bottom of the banknote in contact with each other, and rotate upward to separate from the banknote. It is like this.

The first support 109a has left and right armed with banknote holding levers 132, which are separated from each other, and supports the banknotes by contacting the left and right banknotes. In the illustrated example, a roller 132a that rolls along the surface of the bill is loosely fitted to this lever, and a hanging piece 132b that supports the lower end of the bill is also loosely fitted to the lever. This hanging piece 132b has a spring 13 for holding the posture shown in FIG.
3 is hanging to prevent the bottom edge of the bill from bending.

On the other hand, the second support 109b is provided with levers 134 on the left and right arms like the first support, and this roller is composed of a shaft collar that can roll along the bill surface.
135 is loosely fitted.

(Regulation of front support) The front support 109 having the above-mentioned configuration is route 47 between l _{2 in} FIG.
The banknotes sent from are held in an upright position, the banknotes are block-transferred between l ₃ shown in the figure, and the backup plate described above is transferred between l _1.
It is delivered to 108, and then returns to the right end to hold the next inflowing bill. Therefore, the front support 109 makes a progressive movement according to the amount of banknotes accumulated between l ₂ shown in the figure, supports the banknotes in a standing state together with the backup plate 108 described later between l ₃ and carries them in blocks, and transfers between l ₁ from the banknotes. It detaches and delivers it to the backup plate 108, returns to the right end again, and holds the next inflowing bill between l ₂ .

Therefore, the front support 109 has a spring 136 for urging it to the home position on the right end side shown in FIG. 5, a ratchet lock mechanism 137a for holding the position while advancing between l ₂ and the above-mentioned urging force between l ₁ . The ratchet lock mechanism 137b that holds the position of the rear support 111 and the backup plate 108, which will be described later, by canceling the return force of the spring 136, and the front support 109 from the banknote in the front row between l ₁ Release means 138 for releasing
(FIG. 4).

In the drawing, an urging spring 136 has one end wound around the carriage 130 portion of the front support 109 and the other end wound around a drive pulley 131 of a rear support 111 described later. Thus the front support 109 is a spring 136 having a base end portion to the pulley 131 is wound in the carriage 130 and integrated with the always biased by the biasing spring 136 to the right end of the home position rear support 111 is illustrated l ₃ As the pulley rotates, its entire length expands and contracts so that a substantially uniform tensile force acts in the section. And front support
A ratchet wheel 139 and a ratchet pawl 140 are attached to the carriage 130 of 109, and a rack 141 with which the wheel 139 meshes is provided in the section of l ₂ and l ₁ , and section l ₃
It is not provided in the part.

The ratchet mechanism in FIG. 5 is configured to allow counterclockwise rotation but not clockwise rotation and to maintain its position against the restoring force of the biasing spring 136 (clockwise rotation of the ratchet wheel). The illustrated rack 141 can be disengaged from the ratchet wheel by a manual lever 142 as shown by a chain line.

This is because when the front support 109 is moved to the left due to a paper jam or the like, the front support 109 is locked at that position, so that it cannot be returned to the home position at the right end. Therefore, the lock (ratchet engagement) is released by the manual lever 142, and the bias spring is used to return.

On the other hand, a pin 143 is provided on the front support 109a so as to project as shown in FIG.
44 is fixed to the frame side, and this pin is the cam plate 144
It is regulated to slide back on the upper surface and slide forward on the lower surface. The cam plate 144 is provided in the section l ₃ .

Therefore, the front support 109 is rotatable upward about the shaft 131, but when the pin 143 engages with the lower surface of the cam plate 144 and moves forward, the upward rotation is blocked and moves while supporting the bill front surface. Figure 2 After moving the bill to the left end,
143 is released from the restraint of the cam plate 144 and is allowed to move upward.

Therefore, there is a releasing means 138 connected to the actuating solenoid 145 at the left end thereof, and the pin which engages with the releasing means 138 when the releasing means 138 is operated from the state of FIG. 143 is lifted to a position along the upper surface of the cam plate 144.

At this time, the first front support 109a is gradually separated from the front of the bill because the pin 143 planted therein is lifted by the releasing means 148, and then engaged with the second support to lift the second front support 109b. A projection 145 is provided on the first one.

Further, when the first and second supports 109 are lifted upward, the pin 143 disengages the ratchet pawl 140 from the wheel 139, and the first and second supports 109a and 109b are actuated by the urging spring 136 to move in the returning direction. Through movement, pin 143 is a cam plate
It rides on the upper surface of 144 and is regulated by this, and the first and second front supports return while being lifted upward. When the front support returns to the home position at the right end, the pin 143 is disengaged from the upper surface of the cam plate 144, and the first and second front supports return to the state of FIG.

(Structure of Rear Support) A pair of rear supports 111 for constraining the banknote bundle from the front and back and transporting it to a predetermined position together with the front support 109 having the above structure are provided on the left and right sides of the banknote bundle as shown in FIG. It is slidably fitted to the arranged stems 150 and 151, and is fixed to timing belts 152 and 153 that also run in parallel with the stems 150 and 151.
2, 153 are suspended on the same drive shaft 54 and are connected to a forward / reverse rotation motor 155.

When the drive shaft 154 rotates to the right, it travels to the left in the drawing to convey the banknote bundle, and conversely, when it rotates to the left, it returns to the home position on the right.

Next, the operation will be described.

As described above with reference to FIG. 1, the banknote deposit process and the banknote dispense process are repeated between the recycle stacker 9 and 11 and the customer service port 4 through the discriminating unit 5. Is a banknote bundle for withdrawal, and the deposited banknotes are stored for each of the left and right blocks, and when the left banknotes for withdrawal are running out, and when all the stored banknotes are collected in the safe 15. The block is conveyed from the deposit banknote block on the right side toward the payout outlet 101 side on the left side.

As for the transportation instruction, the discrimination unit 5 counts outflowed banknotes and inflowed banknotes by denomination, manages the banknotes stored therein by the central processing unit, and instructs the ATM.

When this instruction is given, the forward / reverse rotation motor 155 for driving the rear support 111 rotates the drive shaft 154 to the right side in FIG. Then, the rear support moves to the left side in FIG. 2, pushes down the stopper 110 to abut against the back surface of the banknote bundle, and pushes it forward. Then, the front support 109 is likewise pushed to the left side and is conveyed while holding the bundle of paper sheets in between. When the sheet bundle reaches a predetermined position where it contacts the kick roller 103, the limit switch PR14 of the rear support 109 detects this and stops the motor 154, and at the same time the rotary solenoid 1
45 is operated and the releasing means 138 is rotated clockwise in FIG.

Then the pin 143 of the front support 109 is lifted up and the shaft
The support 109 is lifted upward around the 131 to separate from the front row of the banknote bundle.

Then, when the forward / reverse rotation motor 155 is rotated in the reverse direction, the rear support 111 starts returning to the home position,
In the front support 109, the pin 143 rides on the cam plate 144 and returns to the home position position by the urging force of the spring 136.

As described above, in this embodiment, the front support 109 (the second front support 109b of the illustrated embodiment) that supports the front surface of the bundle of paper in the conveying direction is engaged with the bundle of paper (FIGS. 6A and 6B).
The front support 10 is movably mounted between the operating position (c) and the disengaged position (d) shown in the figure (not shown).
The rotatable member 135 is provided at the engaging portion of the sheet bundle 9b.

[Advantages of the Invention] Since the present invention has the above-described configuration, the front support that supports the front surface in the transport direction of the sheet bundle does not roll and disturb its posture when capturing the sheet bundle, After being transported to the target position, it does not roll and disturb the alignment of the sheets in the same way, there is no danger of disturbing the posture of the front row of sheets in particular, and it should be delivered smoothly to the processing operation to be continued. There is an effect that can be.
