Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for processing paper sheets such as banknotes and postcards one by one in order to count, identify, and differentiate the number of sheets. This invention relates to a conveyance processing device for paper sheets that is separated and conveyed.

[Prior Art] A paper sheet conveying and processing device is used to separate and convey paper sheets one by one and perform processing such as counting, identification, discrimination, etc. An example of this paper sheet conveyance processing device is a bill depositing device that deposits banknotes. The banknotes are sent from the banknote outlet to a banknote conveyance path, and a discrimination section installed in the middle of the banknote conveyance path counts the number of banknotes to be conveyed, identifies their authenticity, presence or absence of damage, denomination, etc. It is configured to perform a discrimination process consisting of: and to store the discriminated banknotes in a stacker section provided on the downstream side of the discrimination section in the bill conveyance path.

In order to operate the above-mentioned bill depositing device smoothly, it is necessary to be able to reliably separate the bills put into the hopper section one by one and send them toward the conveyance path. A banknote separation and conveyance means is provided at the banknote exit in the hopper section. Such a separating and conveying means is composed of a drive drum having 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 in sliding contact with the drive drum. When the drive drum rotates and its feeding portion 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 conveyance path. has traditionally been used. Also, after one preceding banknote is carried out, it is for guiding the following banknote towards the above-mentioned separating and conveying means.

It is also known that an auxiliary feed roller that rotates eccentrically is attached to the side closer to the banknote input section than the drive drum in the hopper section.

As mentioned above, in the case where the separating and carrying out means and the auxiliary feeding roller are attached to the separating and carrying out means, when a large number of banknotes are installed in the hopper section, the weight of the banknotes itself can easily move the banknotes to the separation drum or the auxiliary feed roller. It is possible to press the banknotes against the feed roller, but when the number of banknotes in the hopper becomes low, the banknotes do not come into close contact with the separating drum or the auxiliary feed roller, and the banknotes float up due to their rotation, resulting in a state of idle rotation. There is a possibility that the banknotes will be stored away and the banknotes will not be able to be taken out. Therefore, a friction roller such as a rubber roller is provided in sliding contact with the center of the separation drum, and the friction roller presses the banknotes against the separation drum to prevent the banknotes from floating up. A structure designed to ensure reliable delivery is used.

[Problem to be solved by the invention 1 As mentioned above, if a friction roller is attached,
This makes it possible to reliably feed out every last bill, but since the bill comes into almost point contact with the friction roller at its center, it is difficult to There is no particular problem if the bill comes into contact with the friction roller in a straight state, but if the edges of the bill are not aligned when it is initially inserted, or if the bill moves while the device is operating, it may cause friction at an angle. If the banknotes come into contact with the rollers, they will be wound up in the separation drum in that state, and the banknotes will be conveyed in a diagonal direction of 1 m. If the banknotes are sent out onto the banknote conveyance path in such a skewed state, there will be problems such as jamming occurring during the conveyance or the possibility that the banknotes will not be able to be discriminated by the discrimination section.

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

[Means for Solving the Problems 1] 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 are fed in a stacked state, and the paper sheets are fed into the hopper section. In the paper sheet transport processing apparatus, the paper sheet conveying and processing apparatus is provided with a separating and carrying means for separating and carrying out the paper sheets one by one at the paper sheet output port, and the paper sheet is pressed down from above the paper sheets inputted into the hopper section. The pressing means has an operating position where it presses the paper sheet when it is thrown into the hopper section, and a retracted position where it is located outside the hopper section and allows the paper sheet to be thrown into the hopper section. The feature is that the structure is movable between the two.

[Operation 1] A sheet pressing means is disposed at a retracted position outside the hopper section, and a plurality of sheets are stacked and fed into the hopper section. After the sheet handling, the sheet pressing means is moved to the operating position so that the sheet pressing means presses the sheets stacked in the hopper section from above. Therefore, when the separating and carrying out means is activated, the paper sheets pressed by the paper sheet pressing means are
Even without using the weight of the bill itself, it is sufficiently pressed against the separating and carrying out means, so that the paper sheet can be smoothly carried out to the bill conveying path by the separating and carrying out means, and this separating and carrying out means It does not cause misalignment when it gets caught in the water. Therefore, it is possible to reliably separate and carry out all the paper sheets in the hopper section up to the last one in a straight posture.

[Embodiment 1] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. In this embodiment, as a paper sheet conveyance processing device,
A bill deposit processing device that performs bill deposit processing will be described.

FIG. 1 shows an overall configuration diagram of the bill depositing device. In the figure, l indicates a hopper section, 2 indicates a bill conveyance path, 3 indicates a discrimination section, and 4 indicates a stacker section.The hopper section l is formed with a bill exit port 1a, and the bill conveyance path 2 is It is constructed by combining a feed roller 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. , count the number, truth or falsehood.

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

In order to carry out the banknotes 5 from the paper W5 outlet 1a of the hopper part 1 to the banknote conveyance path 2, a banknote separation and carry-out means 7 is installed in the forming part of the banknote outlet 1a in the hopper part 1. ing. The banknote separating and discharging means 7 consists of a drive drum 9 rotated by a motor 8 and a driven roller 10 in sliding contact with the drive drum 9, with a part of the drive drum 9 facing into the hopper section l. ing. A feeding portion 9a is formed on the outer peripheral surface of the drive drum 8 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 portion is finished smooth to prevent two or more banknotes 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, similar to the drive drum 9 described above, so that when banknotes 5 are put into the hopper section 1'', the bottom layer of the banknotes 5 is A transmission belt 12 is wound between the auxiliary feed roller II and the drive drum S, and the auxiliary feed roller 11 is driven via the transmission belt 12. It is configured to rotate following the drum 9. Also, this auxiliary feed roller 11
rotates eccentrically, thereby moving the banknotes toward the drive drum 9 while vibrating them.

Next, this banknote depositing device is equipped with a banknote suppressing means 13 that presses down the banknotes 5 from above. As shown in FIGS. 2 and 3, this banknote suppressing means 13 includes a banknote pressing arm 14 and a pressing roller 15 rotatably attached to the tip of the banknote pressing arm 14. 1
4 is configured such that a press roller 15 can be pressed against the upper part of the banknotes 5 put into the hopper part l. This banknote holding arm l4 is located outside the hopper part l,
The bill presser arm 14 is moved between a retracted position in which the hopper section 1 is opened and an operating position in which the presser roller 15 protrudes into the hopper section 1 and presses the bill 5 from above.
The other end is supported by an L-shaped lever 18 that rotates about a pivot point 17 by a solenoid 16 . Then, the lever 18 is biased by the spring 19,
The presser lever 17 is always biased to the above-mentioned retracted position, and when the solenoid is energized, the banknote presser arm 14 can be displaced to the operating position against the spring 19. has been done.

Further, the hopper section 1 is provided with a shutter 20 for closing the bill exit port 1a.
0 is disposed in a closed position where the outlet 1a is closed when the device is not in operation, and a banknote 5 is inserted into the hopper section 1.
By aligning the edges of the shutter 20 with the wall surface of the shutter 20, the edges can be aligned, and when the device is operated, the paper can be removed from the hopper section 1. In order to allow the P55 to be carried out, the
a can be moved to the open position. In order to displace the shutter 20, the shutter 20 is swingably supported on a fulcrum 21,
a curved operating section 2 having a cam function to displace the shutter 20 to a portion extending from the fulcrum 21 to the other end;
2 is extended, and the spring 2 is attached to the actuating portion 22.
3, the shutter 20 is always urged in the direction of closing the exit 1a. The actuating portion 22 is configured so that the shutter 20 can be moved to the open position by moving a roller 24 attached to the tip of the lever 18 constituting the banknote suppressing means 13. Note that 25 indicates a sensor that detects whether or not the banknotes 5 are inserted into the hopper section 1.

The unembodied example is constructed as described above, and its operation will be explained next.

First, the shutter 20 is held in a state in which no electricity is applied to it, the bill holding arm 14 of the bill suppressing means 13 is held in the retracted position, and the shutter 20 is held in the closed position shown by the solid line in FIG. None, a predetermined number of banknotes 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 at the same time, the auxiliary feed roller 11 connected to the drive drum 9 via the transmission belt 12 is rotated, and the hopper section 1 is rotated.
The banknotes 5 inside are brought into contact with the shutter 20 while vibrating in the vertical direction, and the ends of the banknotes 5 are aligned along the shutter 20. Here, if the shutter 20 is formed obliquely toward the conveyance direction of the banknotes 5, the ends of the banknotes 5 will be aligned in a wedge shape, and the conveyance condition will be extremely good.

When the solenoid 20 is energized after the ends of the banknotes 5 have been aligned for a predetermined period of time, the lever 18 rotates in the direction of the arrow shown in FIG. By rolling along the shutter 20, the shutter 20 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 14 rotates and tilts toward the inside of the hopper section 1, and the press roller 15 attached to the tip of the banknote holding arm 14 is displaced to the operating position where it presses the banknote 5 from above. Become.

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

As described above, the banknotes 5 in the hopper section 1 are sequentially conveyed toward the banknote conveyance path 2 by the operation of the separating and unloading means 7, but since the banknotes 5 are held down from above by the press rollers 15, Based on the suction force of the solenoid 16, the driving drum 9 and the auxiliary feed roller 11 are pressed with sufficient force, so that even if the number of banknotes in the hopper section 1 decreases, the auxiliary feed roller 11 can send out the banknotes, and Separation and unloading by the drive drum 9 is performed smoothly. Moreover, unlike the friction rollers of the prior art described above, there is no member that makes almost point contact with the banknotes to be conveyed. S and driven roller 10
Therefore, the conveyance condition is very good, and there is no risk of skewing or the like. and 1
By pressing the banknotes with the presser roller 15, the presser roller 15 rolls over the banknotes when the last banknote is carried out, so that no excessive force is applied to the banknotes. This will not cause any inconvenience such as damage or damage.

As described above, the banknotes are sequentially carried out to the banknote transport path 2,
After being sent along the banknote transport path 2 to the validation section 3 and subjected to validation, the banknotes after validation are removed by the banknote removal means 6. ! ! ! ! They are taken out from the conveyance path 2 and stacked on the stacker section 4. When all the banknotes in the hopper section 1 are taken out, this is detected by the sensor 25, and based on this detection signal, the solenoid 16
Stop energizing. As a result, the shutter 20 returns to the closed position that closes the bill exit port 1a, and both the bill holding arm 14 and the hopper portion 1 are retracted, thereby completing the bird deposit operation. When performing the next deposit process, the banknote holding arm 14 is in the retracted position, so the hopper part l is open, and therefore, there is no possibility that it will interfere with the work of inserting banknotes into the hopper part l. 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. Further, although the bill holding arm 14 is configured to be displaced between the operating position and the retracted position by the solenoid 16, a cam equivalent means may also be used as this displacement means. Further, while the force for pressing the banknote is generated by the suction force of the solenoid 16, a spring may be applied to the banknote holding arm 14 so that the pressing force is obtained by this spring, or the pressing roller 15 may be replaced with a spring. Alternatively, weights may be used.

[Advantageous Effects of the Invention 1] As detailed above, the paper sheet conveying and processing device according to the present invention has a simple structure because it is provided with a sheet pressing means that presses the sheets put into the hopper section from above. Thus, it becomes possible to reliably carry out the paper sheets inputted into the hopper section to the paper sheet discharging path until the last one, and moreover, in a good conveyance state.
