Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention is for processing paper sheets such as banknotes, postcards, etc. in order to perform processing such as counting the number of sheets, distinguishing them, and identifying display contents. This 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 separate and convey paper sheets one by one and perform processing such as counting and identification. For example, there is a banknote depositing device that performs banknote deposit processing. This banknote depositing device has a hopper section into which a plurality of banknotes are input, and the banknotes input into the hopper section are sent from the banknote output port to a banknote conveyance path, and a banknote depositing apparatus is installed in the middle of the banknote conveyance path. The discrimination section performs discrimination processing that includes counting the number of conveyed banknotes, identifying their authenticity, presence or absence of damage, and denomination.

Furthermore, the stacker section provided on the downstream side of the discriminating section in this bill conveyance path is configured to store the bills after being discriminated.

Here, in order to smoothly and accurately carry out the operation of the above-mentioned banknote depositing device, that is, the transport of banknotes on the banknote transport path and the verification process in the verification section, it is necessary to It is necessary to reliably separate and transport the banknotes until they reach the banknotes, and to send them straight toward the banknote conveyance path. For example, two or more banknotes may overlap in whole or in part in a double or chained state, or may be transported in a skewed state, which not only makes identification impossible, but also causes inconveniences such as jamming during transport. will occur. For this purpose, the banknotes inserted into the banknote outlet in the hopper section are
Conventionally, devices have been used that are provided with a separating and conveying means for separating the bills one by one and sending them out to a bill conveying path.

The separating and conveying means in the prior art is comprised 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 comes into sliding contact with the drive drum. When the driving drum rotates and the feeding section engages with a banknote, the banknote is wound between the drive drum and the driven roller, thereby separating the banknotes one by one and carrying them out toward the banknote transport path. I try to do that. In addition, in order to guide the subsequent banknotes toward the aforementioned separating and conveying means after the preceding banknote is carried out,
It is also known that an auxiliary feed roller that rotates eccentrically is attached to the side of the hopper section closer to the banknote input section than the drive drum.

[Problem to be Solved by the Invention 1] If the above-described separating and conveying means and an auxiliary feeding roller are attached thereto, it becomes possible to separate and carry out the banknotes relatively well.

In order to more reliably prevent duplicates, chains, and skewed conveyance of banknotes, it is necessary to align the edges of the banknotes when feeding them into the hopper section. however,
Some of the banknotes being deposited in the banknote depositing device are bent or wrinkled, and it is not always possible to input the banknotes into the hopper with their edges aligned accurately. Also, due to carelessness or other reasons, bills may be thrown into the hopper section without being tidy. In such cases, it is necessary to prevent the occurrence of double, chained, skewed, etc. of the bills being conveyed as described above. It turns out you can't do it.

In addition, when the regency banknotes are installed in the hopper,
Due to the weight of the banknotes themselves, the banknotes can be pressed against the separation drum and auxiliary feed roller without any problem. However, as the number of banknotes in the hopper decreases, the banknotes do not come into close contact with the separation drum or auxiliary feed roller, and their rotation becomes difficult. This may cause the banknotes to float up and become idle, making it impossible to carry out the last few banknotes.

Therefore, a rubber roller is provided in sliding contact with the center of the separation drum, and the rubber roller presses the banknotes against the separation drum to prevent the banknotes from floating up and to ensure that the last banknote is sent out. However, since the banknotes come into almost point contact with the rubber rollers, the edges of the banknotes may not be aligned at the beginning of insertion, or the device may not operate properly. If the banknote moves inside and comes into contact with the rubber roller diagonally, the banknote will be conveyed in a skewed state.

The present invention has been made in view of the above points, and its purpose is to reliably and accurately transport paper sheets fed into the hopper section to the last one, with a simple configuration. It is an object of the present invention to provide a conveying and processing device for paper sheets that can handle paper sheets.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention forms a paper sheet outlet in a hopper section into which a plurality of sheets of paper are input in a stacked state, and the paper sheets are input into the hopper section. In the paper sheet conveyance processing apparatus, the paper sheet conveyance processing apparatus is provided with a separating and carrying out means for separating and carrying out the paper sheets one by one at the paper sheet carrying out outlet, and a shutter for opening and closing the carrying out outlet and a shutter for opening and closing the carrying out outlet, and a shutter for opening and closing the carrying out outlet, and a shutter for opening and closing the carrying out outlet, and a shutter for opening and closing the carrying out outlet, and a shutter for opening and closing the carrying out outlet; a vibrating member that vibrates the paper sheets, and a paper sheet pressing means that presses the paper sheets input into the hopper section from above,
While the outlet is closed, the sheet pressing means is held in a position evacuated from the hopper section, and the vibrating member of the sheet aligning means is operated to align the end of the input sheet along the shutter. The paper sheets are arranged in the same position, and when the outlet is opened, the paper sheets are pressed down by the sheet pressing means.

[Operation 1] Then, the paper sheet exit in the hopper section is closed by the shutter that constitutes the paper sheet alignment means, and the paper sheet pressing means is retracted from the hopper section, and a plurality of sheets of paper are placed in the hopper section. Add the leaves.

When the vibrating member is activated to vibrate the input paper after the paper is inserted, the edges of the paper are aligned along the shutter.

After the ends of the sheets are aligned as described above, the shutter is moved to open the sheet exit, and the sheet pressing means is activated to contact the sheets in the hopper section. This keeps the edges of the paper sheets aligned.

Therefore, when the separation and carry-out means is activated, the paper sheets pressed by the paper sheet pressing means are sufficiently pressed against the separation and carry-out means, and the paper sheets are smoothly carried out to the paper sheet conveyance path by the separation and carry-out means. In addition, since the edges of this paper sheet are aligned as described above,
The sheets are reliably separated one by one and transported to the paper conveyance path in extremely good condition, eliminating the risk of double sheets, chains, skewing, etc. This makes it possible to reliably prevent inconveniences such as jamming occurring inside the device or inability to perform discrimination in the discrimination section. Moreover, since the paper sheets are held down by the paper sheet pressing means, they are sufficiently pressed against the separating and carrying out means without using the weight of the banknotes themselves. It becomes possible to reliably separate and carry out up to one sheet.

[Example] Hereinafter, an example of the present invention will be described 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.

FIG. 1 shows the overall configuration of the banknote depositing device, in which 1 is a hopper section, 2 is a banknote conveyance path, and 3
4 is a discrimination section, and 4 is a stacker section. The hopper section 1 is formed with a banknote outlet 1a, and the banknote conveyance path 2 is constructed by combining a feed roller 2a and a guide plate 2b provided at an appropriate position, and the banknote transport path 2 is configured by combining a feed roller 2a and a guide plate 2b provided at an appropriate position. Is the paper ff55 sent out from the banknote outlet 1d? The sheets are transported to the Ie5 transport path 2, and the number of sheets is counted in the discrimination section 3 to determine whether they are genuine or false.

A discrimination process consisting of determining the 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 and stacked in the stacker section 4. It is composed of

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 hopper section 1, a banknote separation/carryout means 7 is installed at a portion of the hopper section 1 where the banknote carryout port 1a is formed. The banknote separating and discharging means 7 includes a drive drum 9 rotated by a motor 8 and a driven roller 10 in sliding contact with the drive drum 9.
A part of it faces into the hopper section 1. The feeding portion 3a is formed by pasting rubber or the like with a large friction coefficient on the outer peripheral surface of the driving drum 9 at an angle corresponding to a length equal to or less than the length of the short side of the banknote 5. has a smooth finish to prevent more than one banknote from being continuously fed at the same time.

At a position closer to the banknote input section of the hopper unit 1 than the drive drum 8, there is an auxiliary feed roller 1 that guides subsequent banknotes toward the drive drum 9 after one banknote 5 is discharged.
1 is mounted on the auxiliary feed roller 11, and a part of the auxiliary feed roller 11 also faces into the hopper section 1 in the same way as the drive drum 9 described above, and when banknotes 5 are put into the hopper section 1, the bottom layer of the banknotes 5 is It is designed so that it can be brought into contact with objects. A transmission bell 1-12 is wound around between the auxiliary feed roller 11 and the drive drum 9, and the auxiliary feed roller 11 is rotated following the drive drum 9 via the transmission belt 12. It has become. In addition, this auxiliary feed roller 11
rotates eccentrically, thereby moving the banknotes toward the drive drum 9 while vibrating them.

Next, this bill depositing device is provided with a bill aligning means 13 for aligning the ends of the bills 5 placed in the hopper section 1. As shown in FIGS. 2 and 3, this bill aligning means 13 is composed of a shutter 14 that opens and closes the bill exit 1a of the hopper section 1, and the aforementioned auxiliary feed roller 11. 14 is rotated about a fulcrum 15, so that the banknote exit 1a can be moved to a closed position, as shown by the solid line in FIG. It is possible to move between positions. The shutter 14 has a curved operating section 16 that functions as a cam and extends in the opposite direction from the section attached to the fulcrum 15.
It is always biased by a spring 17 attached to B to be in the closed position. Further, in order to displace the shutter 14 to the open position, a lever 1 having a roller 18 attached to the tip thereof is provided.
The proximal end of the lever 19 is L-shaped, and its bent portion is pivoted to a rotation fulcrum portion 20, and its end portion is connected to a solenoid 21. and,
When the solenoid 21 of the lever 18 is de-energized, the roller 18 attached to the tip of the lever 18 is separated from the operating part 16 connected to the shutter 14 by the action of the spring 22, and when the solenoid 21 is energized, the roller 18 is separated from the actuating part 16 connected to the shutter 14. , the lever 18 rotates in the direction shown by arrow A in FIG. 2 against the biasing force of the spring 22, and moves the roller 18 along the actuating portion 16, thereby displacing the shutter 14 to the open position. It is configured so that it can be done.

In addition to the above-mentioned banknote aligning means 13, a banknote suppressing means 23 which operates in conjunction with the banknote aligning means 13 is installed. This bill pressing means 23 includes a bill pressing arm 24
and a presser roller 25 rotatably attached to the tip of the bill presser arm 24, and the bill presser arm 24 can press the presser roller 25 against the upper part of the banknotes 5 thrown into the hopper section 1. It looks like this. This banknote holding arm 24 is located outside the hopper section 1, and the hopper section 1 is opened at a retracted position and protrudes into the hopper section 1.
The other end of the bill presser arm 24 is supported by the lever 19 described above in order to move the bill presser arm 24 between the operating position and the operating position where the presser roller 25 presses the bill 5 from above. Note that 26 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 21 is kept de-energized, the shutter 14 is kept in the closed position shown by the solid line in FIG. 2, and a predetermined number of bills 5 are stacked and thrown into the hopper section 1. Therefore, when the motor 8 is operated, the drive drum 9 is rotationally driven by the motor 8, and the auxiliary feed roller 11 connected to the drive drum 9 via the transmission belt 12 is also rotated. As a result, the banknotes 5 in the hopper section 1 are about to be moved toward the banknote exit la side while being vibrated from the lower part thereof. However, since the banknote output port 1a is closed by the shutter 14, the banknotes 5 in the hopper part 1 are vibrated in the vertical direction and are struck by the shutter 14, so that the banknotes 5 are The ends will be aligned along the shutter 14.

Here, if the shutter 14 is formed obliquely toward the conveyance direction of the banknotes 5, the ends of the banknotes 5 will be aligned in a wedge shape, so that the conveyance conditions will be extremely good as will be described later.

After continuing to align the edges of the banknotes 5 for a predetermined period of time, when the solenoid 21 is energized, the lever 19 rotates in the direction of arrow A in FIG. By rolling along the shutter 14, the shutter 14 is displaced to the open position shown by the dashed line in the same figure.
The bill exit port 1a is opened. At the same time, the banknote holding arm 24 rotates and tilts toward the inside of the hopper section 1, and the press roller 25 attached to the tip of the banknote holding arm 24 is displaced to the operating position where it presses the banknote 5 from above. Become. As a result, the banknotes 5 are transferred to the banknote aligning means 13 as described above.
This will keep the ends aligned. Therefore, in order to more reliably maintain the posture of the banknote 5, it is preferable that the shutter 14 is opened after the presser roller 25 of the banknote presser arm 24 comes into contact with the banknote 5. Even if the pressing by No. 25 is delayed a little, there is no problem in practice. In this case, if the bill aligning means 13 and the bill pressing means 23 are operated by a single solenoid 21, this operating mechanism is simplified and the responsiveness is improved.

Here, since the auxiliary feed roller 11 and the drive drum 9 continue to rotate, the auxiliary feed roller 11 feeds out the lowest layer of banknotes toward the drive drum 9, and the feed portion formed on the drive drum 9 When 9a engages with this banknote, the banknote is caught between the drive drum 9 and the driven roller 10 and the paper! ! It will be carried out towards the lI5'rX feed path 2. At the same time, the subsequent bill is fed by the auxiliary feed roller 11 to a position where it comes into contact with the driving drum 9, but it remains in that position until the feeding section 8a of the driving drum 9 engages with this subsequent bill. As a result, the banknotes are sent out to the banknote transport path 2 in a separated state one by one.

Here, the ends of the banknotes 5 thrown into the hopper section 1 are aligned, and their posture is stabilized by the banknote suppressing means 23, so that the banknotes 5 are straight without hitting unevenly. If the sheets come into contact with the drive drum 3 one by one, they will bend, and two or more sheets will not be sent toward the separation/export means 7 or be brought into contact with the drive drum 9 in an oblique state. The banknotes will not be conveyed in an abnormal state such as a double state in which the whole banknotes overlap, a chain state in which parts of the banknotes overlap, or a state in which the banknotes are skewed even if they are separated one by one. It can be conveyed in extremely good conveyance conditions.

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.

In addition, since the banknotes 5 are pressed down from above by the presser roller 25, sufficient force is exerted to press the banknotes against the drive drum 9 and the auxiliary feed roller 11 based on the suction force of the solenoid 21. Even if the number of bills is small, the auxiliary feed roller 11 can smoothly feed the banknotes, and the drive drum 9 can smoothly separate and carry out the banknotes. Then, by pressing the banknotes with the presser roller 25, when the last banknote is carried out, the presser roller 25 rolls on the banknote, so that no excessive force is applied to the banknote. There will be no inconvenience such as damage caused by splashing.

As described above, the banknotes are sequentially carried out to the banknote transport path 2,
After being sent along the banknote conveyance path 2 to the discrimination section 3 and subjected to the discrimination, the banknotes after the discrimination are taken out from the banknote conveyance path 2 by the banknote extraction means 6 and stacked in the stacker section 4. That will happen. When all the banknotes in the hopper section 1 are removed, the sensor 26 detects this, and when the solenoid 16 is de-energized based on this detection signal, the shutter 14 moves to the closed position to close the banknote exit 1a. When the banknote holding arm 24 returns to its original position and is also retracted from the hopper section 1, the depositing operation is completed. When performing the next deposit process, the banknote holding arm 24 is in the retracted position, so the hopper section 1 is open, and therefore, there is no possibility that the work of inserting banknotes into the hopper section 1 will be hindered. There isn't.

In the above-mentioned embodiment, the paper sheet conveyance processing apparatus is configured as a banknote depositing apparatus for depositing banknotes. In addition to this, as long as the process involves counting the number of sheets, identifying their type, display contents, etc., and discriminating them,
It goes without saying that it can also be used, for example, as a device for identifying and sorting postal codes written on postcards. Furthermore, although the banknote aligning means 13 and the banknote pressing means 23 are configured to be operated by the solenoid 21, as shown in FIG. Boards 32a, 32
It is also possible to use a cam drive operated by b. In the case of cam drive in this way, the timing of both means can be set freely, so that after the banknotes are pressed by the banknote suppressing means 23, the shutter 14 constituting the banknote aligning means 13
It is now possible to set the timing to open the banknotes, and it is possible to hold the banknotes whose edges have been aligned in an extremely stable state, resulting in an even better discharge condition in the banknote discharge path 2. . Furthermore, an auxiliary feed roller 11 is used as a vibrating member constituting a banknote alignment mechanism that aligns the edges of banknotes, and the auxiliary feed roller 11 has the r4 function of guiding subsequent banknotes toward the vibration member and the separating and carrying out means 7. Although the vibration member is shown to be exerted, the vibration member may be provided separately from the auxiliary feed roller 11.Furthermore, the pressing force against the banknote 5 by the banknote suppressing means 23 is generated by the suction force of the solenoid 21. However, a spring may be applied to the banknote holding arm 24 to obtain pressing force, or a weight or the like may be used in place of the holding roller 25.

[Advantageous Effects of the Invention 1] As described in detail above, the paper sheet conveying and processing apparatus according to the present invention includes a sheet aligning means for aligning the edges of the sheets loaded into the hopper section before being unloaded; Since a sheet pressing means is provided to press the sheets from above, the sheets placed in the hopper are reliably conveyed down to the last sheet, and are directed toward the sheet output path so that they are conveyed in good condition. This eliminates the risk of two or more sheets overlapping or being chained together, or even if they are separated one by one, being conveyed at an angle, and the paper sheet transport path is This makes it possible to reliably prevent problems such as jamming during transportation or inability to differentiate in the identification section.
