Description

[Detailed Description of the Invention] Industrial Application Field 1 The present invention is applied to paper sheets such as banknotes, postcards, etc. in order to perform processing such as counting the number of sheets, distinguishing them, reading displayed information, etc. The present invention relates to a conveyance processing device for paper sheets that separates and conveys paper sheets one by one.

[Prior art 1 A paper sheet conveyance processing device is used to carry out processes such as counting and discrimination while separating and conveying paper sheets one by one. For example, there is a bill depositing device that performs bill deposit processing. This banknote deposit device is
It has a hopper part into which a plurality of banknotes are thrown, and the banknotes thrown into the hopper part are sent from the banknote outlet to a banknote conveyance path, and are checked by a discrimination section provided in the middle of the banknote conveyance path. Counting the number of sheets, their authenticity, and whether or not they are damaged.

It is configured to perform a discrimination process consisting of identifying the denomination, etc., and to store the banknotes after the discrimination process in a stacker section provided on the downstream side of the discrimination section in the bill conveyance path.

Here, in order to smoothly carry out the discrimination processing in the above-mentioned discrimination section and the conveyance of banknotes on the banknote conveyance path, it is necessary to reliably separate the banknotes put into the hopper section one by one, and to ensure that the banknotes are separated one by one along this conveyance path. You need to send it straight. For example, if two or more banknotes are transported in a double or chain state where all or part of them overlap, or if they are transported in a diagonal state, not only will it become impossible to identify them, but also jamming may occur during transport. This will cause inconvenience. In order to prevent such inconvenience, a device is conventionally known that is provided with a minute conveyance means for separating the banknotes put into the hopper part one by one and sending them out to the banknote conveyance path.

This separating and conveying means is composed of a drive drum, which has a feeding section formed by pasting a member with a large friction coefficient such as rubber on a part of its outer circumferential surface, and a driven roller that is in sliding contact with the drive drum. When the drum rotates and the feeding section engages with a banknote, the banknote is wound between the driving drum and the driven roller, thereby separating the banknotes one by one and transporting them toward the banknote transport path. There is. In addition, after one preceding banknote has been sent out, in order to guide the following banknote toward the above-mentioned separating and conveying means, an auxiliary feeder that rotates eccentrically toward the side of the hopper section closer to the banknote input section than the drive drum. There are also known devices that are equipped with rollers.

[Problem to be Solved by the Invention 1] If the above-mentioned minute conveyance means and an auxiliary feed roller are attached thereto, banknotes can be fed out relatively well, but it is not possible to send out the banknotes more reliably. In order to prevent duplicates, chains, and skewed conveyance of banknotes, it is necessary to align the ends of the banknotes when feeding them into the hopper section. However, some of the banknotes that are deposited in the banknote deposit device are bent or wrinkled, so it is difficult to insert the banknotes into the dustbin with the edges aligned accurately. In some cases, it may be difficult to load the banknotes into the hopper section due to carelessness, etc., without tidying up the banknotes. It becomes impossible to prevent it.

The present invention has been made in view of the above points, and an object of the present invention is to align the edges of paper sheets fed into a hopper section, thereby making it possible to align the edges of two or more paper sheets. Another object of the present invention is to provide a conveying and processing device for paper sheets that can reliably prevent paper sheets from being conveyed in a double or chained state in which parts of the sheets overlap or in a skewed state.

[Means for Solving the Problems 1] In order to achieve the above-mentioned object, the present invention provides a hopper section into which a plurality of paper sheets are loaded in a stacked state, and a paper sheet exit in the hopper section. In the paper sheet transport processing apparatus, the paper sheet transport processing apparatus is equipped with a separating and transporting means that separates the paper sheets one by one and sends them out to the paper sheet transport path. The device is characterized by a structure in which a sheet alignment member that hits the edge of the inserted paper sheet is installed, and the edges of the input paper sheets are aligned by swinging the paper sheet alignment member. .

[Function 1] When the sheet alignment member is swung after sheets are thrown into the hopper, the sheet alignment member pulls out the input sheets in the hopper and causes the sheets to vibrate in the direction along the paper surface. is given, the sheet becomes straight in the conveying direction, and its edge is pushed against the front end wall of the hopper section, so that the edges of the sheet are aligned. . The paper sheets arranged straight in this way are reliably separated one by one by the minute conveyance means, and are transported without becoming double, chained, or skewed, and are transported through the sheet transport path. This makes it possible to reliably prevent problems such as jamming during transportation or inability to differentiate in the identification section.

[Embodiment 1] Hereinafter, an embodiment of the present invention will be explained in detail based on the drawings. In this embodiment, a bill depositing device will be described as an example of a paper sheet conveyance processing device.

First, FIG. 1 shows an overall configuration diagram of a bill depositing device. In the figure, 1 is a hopper section, 2 is a bill conveyance path, 3 is a discrimination section, and 4 is a stacker section.The hopper section l is formed with a bill outlet 1d, and the bill conveyance path 2 is It is constructed by combining a feed cola 2a provided at a position and a guide plate 2b, and the banknotes 5 introduced into the hopper section 1 described above are conveyed from the banknote outlet 1a to the banknote conveyance path 2, and then passed through the validation section 3. At the bank, a discrimination process consisting of counting the number of banknotes, determining authenticity, presence or absence of damage, denomination, etc. is performed, and the banknotes after the discrimination process are taken out from the banknote conveyance path 2 by an impeller-type banknote removal means 6. It is configured to be stacked on the stacker section 4.

A banknote transport path 2 is provided from the banknote outlet 1a of the hopper section 1 described above.
In order to carry out the banknotes 5 toward the bank, the hopper section 1 is equipped with a banknote carry-out means 7.

The bill delivery means 7 consists of a drive drum 9 that is rotationally driven by a motor 8 and a driven roller 10 that is in sliding contact with the drive drum 9, with a part of the drive drum 9 facing into the hopper section 1. ing. A feeding portion 9a is formed on the outer peripheral surface of the driving drum 9 by pasting rubber or the like with a large friction coefficient at an angle corresponding to a length equal to or less than the short side length of the banknote 5. The other parts are finished smooth so that two or more banknotes will not be continuously fed at the same time.

After one banknote 5 is carried out, a position closer to the banknote input part of the hopper unit 1 than the drive drum 3 is placed.
Auxiliary feed roller 1 that guides subsequent banknotes to drive drum 9
1 is attached to the auxiliary feed roller 11, and a part of the auxiliary feed roller 11 also faces into the hopper section 1 in the same manner as the drive drum 9 described above. It is designed so that it can be brought into contact with objects. Furthermore, a transmission belt 1 is provided between the auxiliary feed roller 11 and the drive drum 9.
2 is provided in a wound manner, and this auxiliary feed roller 11
is configured to rotate following the drive drum 9 via a transmission belt 12. The auxiliary feed roller 11
rotates eccentrically, thereby moving the banknotes toward the drive drum S while vibrating them.

As shown in FIG. 2, this bill depositing device is provided with a shutter 13 that opens and closes the bill exit port 1a of the hopper portion l, and the shutter 13 rotates about a fulcrum 14 to As shown by a solid line in FIG. 2, it is movable between a closed position where the banknote exit 1a is closed, and an open position where it is opened, as shown by a dashed line in the same figure. The shutter 13 has its fulcrum 14
A curved actuating part 15, which functions as a cam, extends in the opposite direction to the part, and is attached so that it is always in the closed position by a spring 16 attached to the actuating part 15. Forced. Further, in order to displace the shutter 13 to the open position, a lever 18 is provided with a roller 17 attached to its tip, and the proximal end of the lever 18 is L.
The bent portion is pivoted to the rotation fulcrum portion 19, and the end portion is connected to the solenoid 20. When the solenoid 20 is de-energized, the lever 18 has a roller 17 attached to its tip separated from the actuating part 15 connected to the shutter 13 due to the action of the spring 21. When the power is turned on,
The lever 18 rotates in the direction shown by the arrow in FIG. 2 against the biasing force of the spring 21, causing the roller 17 to roll along the operating portion 15, thereby displacing the shutter 13 to the open position. It is configured so that it can be done.

On the other hand, on the side of the banknote input section 1b of the hopper section 1, a bill alignment plate 22 for aligning the banknotes 5 inserted into the hopper section 1 is attached. The bill aligning plate 22 is formed with a bill tapping portion 22a having a length that substantially covers the long side of the bill, and a bent leg portion 22b is formed at the lower end of the bill tapping portion 22a. A swinging fulcrum 23 is attached to the bent portion of the leg 22b.
3 rises toward the banknote input section 1b, and is at an operating position (solid line position in Fig. 2) where it can hit the end of the banknote 5 input into the hopper section 1, and is separated from the banknote input section 1b. The hopper section 1 is tilted in the direction shown in FIG. In order to make this displacement possible, a solenoid 25 is provided that is connected to a link plate 24 that comes into contact with the leg 22b of the bill alignment plate 22, and the link plate 24 is rotatable around a pivot point 26. It is installed. The link plate 24 is normally biased by a spring 27 to hold the bill alignment plate 22 in the retracted position, and when the solenoid 25 is energized, the link plate 24 is rotated in a direction against the spring 27. , so that the bill alignment plate 22 can be moved to the operating position. Here, when the bill aligning plate 22 is in the operating position, the bill aligning plate 22 is biased by the spring 28 and comes into contact with the eccentrically rotating auxiliary feeding roller 11. When it rotates, the striking portion 22a thereof is made to swing. Note that the spring force of the spring 28 acting on the bill alignment plate 22 is equal to the spring force of the spring 27 acting on the link plate 24.
Needless to say, it is set to be smaller than that of .

Further, reference numeral 28 indicates a banknote pressing arm, and a pressing roller 30 is attached to the tip of the banknote pressing arm 29, and the pressing roller 30 presses the banknotes 5 put into the hopper section 1 from above. 5 is configured to be guided toward the separating and carrying out means 7. Further, 31 indicates a sensor that detects whether or not banknotes 5 are placed in the hopper section 1.

This embodiment is constructed as described above, and its operation will be explained next.

First, the solenoid 20 is held in a de-energized state, the shutter 13 is held in the closed position shown by the solid line in FIG. 2, and the solenoid 25 is also de-energized to evacuate the bill alignment plate 22. The banknotes 5 are held in this position and a predetermined number of banknotes 5 are stacked and thrown in from the banknote inlet part ib of the hopper part 1.

When the banknotes 5 are put into the hopper part l, the motor 8 is activated to rotate the drive drum 8, and the solenoid 25 is energized to displace the banknote alignment plate 22 to the operating position. Then, the striking portion 22a is brought into a state where it can come into contact with the end portion of the banknote 5 located on the banknote insertion portion lb side. As a result, the auxiliary feed roller 11 connected to the drive drum 9 via the transmission belt 12 is rotated, but since the auxiliary feed roller 11 rotates eccentrically, the inside of the hopper section l is rotated. Vibration is applied to the paper W55 from the bottom. Moreover, the bill arrangement board 22
Since the auxiliary feed roller 11 is in contact with the auxiliary feed roller 11, the auxiliary feed roller 11 functions as a cam, and the bill alignment plate 22 swings in the direction toward and away from the edges of the banknotes 5. The striking portion 22a strikes the banknote 5. As a result, the banknotes 5 in the hopper section 1 are vibrated in the vertical direction, and the shear closes the banknote exit port 1a.

Even if the edges of the banknotes 5 are thrown into the hopper part 1 in an uneven state, the edges are surely aligned along the shutter 13. Here, by tilting the shutter 13 toward the conveyance direction of the banknotes 5, the ends of the banknotes 5 are aligned in a cylindrical shape, and the conveyance condition becomes extremely good as will be described later.

With the banknote exit 1a closed by the shutter I3,
When the solenoid 20 is energized after the rotation of the feed reloader 11 is continued for a predetermined period of time to ensure that the edges of the banknotes 5 are aligned, the lever 18 rotates in the direction of the arrow in FIG. As the attached roller 17 rolls along the operating part 15 connected to the shutter 13, the shutter 13 is displaced to the open position shown by the dashed line in the figure.
When the banknote outlet 1a is opened, the banknote holding arm 2
2 rotates, and its presser roller 23 presses the bill 5 from above. In this way, by pressing the banknotes from above with the presser roller 23, it is possible to reliably carry out the banknotes down to the next one.

Here, since the auxiliary feed roller 11 and the drive drum 9 are rotating, the lowest layer of banknotes is sent out toward the drive drum 9 by the auxiliary feed roller 11, and the feed portion 9a formed on the drive drum S is When you engage with this banknote,
The banknote is wound up between the drive drum 9 and the driven roller 10 and sent out toward the banknote transport path 2. At the same time, subsequent banknotes are fed out by the auxiliary feed roller 11 to a position where they come into contact with the drive drum 8.
Until the feeding portion 8a of the drive drum 9 engages with this subsequent banknote, it will remain in that position, and as a result, the banknotes will be sent out to the banknote transport path 2 in a separated state one by one. Become.

As mentioned above, the ends of the banknotes 5 put into the hopper section 1 are struck by the banknote alignment plate 22 and are aligned so that they are straight in the conveyance direction, so that the banknotes 5 are Since the sheets come into line contact with the driving drum 9, the sheets will not be conveyed in an abnormal condition such as skewed movement, and the sheets can be conveyed one by one in an extremely good conveyance condition in a straight state. Therefore, there is no possibility that jamming will occur while the banknotes are being conveyed along the banknote conveyance path 2, or that the validation process in the validation section 3 will not be possible. By continuing to hit the edges of the banknotes with the banknote alignment plate 22 until the banknotes 5 are completely removed, the posture of the banknotes can be corrected down to the last banknote. Become.

When the banknotes are sequentially carried out to the banknote transport path 2, they are sent along the banknote transport path 2 to the discrimination section 3 where they are discriminated.
The banknotes after the discrimination are taken out from the banknote transport path 2 by the banknote retrieval means 6 and placed on a star 7 in the stacker section 4. Then, when all the banknotes in the hopper section (3) are taken out, this is detected by the sensor 31, and if the energization of the solenoid 20 is cut off based on this detection signal, the shutter 13 is moved to the closed position where the banknote delivery Dla is closed. At the same time as returning, the bill holding arm 29 is retracted from the hopper section 1. In addition, the solenoid 25 is also returned to the de-energized state,
The bill aligning board 22 is evacuated from the bill insertion part 1b of the hopper part 1. As a result, the hopper section 1 is opened, and the next deposit operation can be performed smoothly.

In the above-mentioned embodiment, the transport processing device for transporting one sheet of paper was configured as a banknote depositing device for depositing banknotes. In addition to this, it can also be used as a device to count the number of postcards, identify their type, display content, etc., and differentiate them. Needless to say, it can be used. In addition, although it has been described that the shutter 13 is in the closed state and the bill alignment plate 22 is operated to cause the inserted bills to hit the shutter 13, the bills are sorted. The arrangement may be such that the arrangement is performed by making it hit against a member such as the wall surface forming the bill exit port 1a of the hopper section 1 or the driven roller 10. Furthermore, the bill arrangement plate 22 may come into contact with the roller 1 that assists the feeding. Although the bill arrangement plate 22 is swung by a separate driving member, it is also possible to swive the bill arranging plate 22 by using a separate driving member.

[Advantageous Effects of the Invention 1] As described in detail above, the paper sheet conveying and processing apparatus according to the present invention includes an aligning member that taps the edges of the paper sheets at the paper sheet input section of the ho and pa section into which the paper sheets are input. Since the paper sheets put into the hopper section can be aligned in a straight state in the conveying direction, the paper sheets can be conveyed in a skewed state.

It becomes possible to reliably prevent jamming from occurring in the middle of the paper sheet conveyance path or from causing inconveniences such as disabling processes such as identification.
