Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is a method for classifying paper sheets, such as banknotes, into denominations,
Or it relates to an apparatus for sorting, counting, and accumulating paper molecules.

[Conventional technology]

General number Coco's pi device is 1+! ? Hl Showa 50-7
As shown in Japanese Patent No. 4492, detection means 26 and 28 detect at least the quality of filter paper sheets that are sequentially carried in and carry them out.
Then, the paper sheet is detected as good by the detection means and the paper sheet is sent to the first
a first conveying means 23b for conveying the paper sheets to the stacking section 35 of the paper sheet, and a second conveying path 23c for conveying the paper sheets, which have been detected as rejected by the detection means and carried out, to the second stacking section 6. . Separation of the paper sheet discharged from the detection means into the first or second conveyance path is performed near the discharge port of the detection means. However, this does not take into consideration the case where the object sent to the conveyance path after passing through the detection means becomes abnormal in its skew (inclination) or the conveyance interval during the conveyance path, resulting in a failure state. In particular, the above-mentioned abnormality is likely to occur when the paper sheet is turned over, and this point is not taken into account.

[Problem that the invention seeks to solve]

The above conventional example does not take into account the reduction of abnormal conditions caused by skew in the conveyance path or abnormal conveyance interval between sheets, and abnormal sheets may jam when being carried into the first stacking section. This makes it difficult to stack paper sheets in the stacking section in the future, forcing the device to stop, which inevitably leads to a decrease in operating efficiency.

The present invention has been made in view of the above points.

The purpose of this is to transport paper sheets that have been rejected by the detection unit directly to the second stacking unit, thereby preventing them from being sent to the front-back reversing unit, thereby improving the operating rate of the device. The object of the present invention is to obtain a paper sheet sorting device that is possible.

[Means for solving problems]

In order to achieve the above object, the present invention includes a detection means for detecting at least the front and back sides of filter paper sheets that are sequentially carried in and transporting them, and a method for transporting paper sheets that are detected as front sides by the detection means and are transported out in a non-inverted state. a first conveyance path, and a second conveyance path provided in parallel with the first conveyance path, which conveys the sheet while reversing the paper leaf detected as the back side by the detection means and carried out, and is detected by the detection means. transporting the above-mentioned both transport paths from the time when the transport path reaches the confluence point of the first and second transport paths,
'1lfD are set to the same value.

[Effect]

Paper sheets detected as front sides by the detection means pass through the first conveyance path, and paper sheets detected as back sides pass through the second conveyance path.The conveyance time is the same no matter which conveyance path they travel through, and the paper sheet passes through the merging point. The feeding interval of the paper sheets will be the same.

〔Example〕

An embodiment of the present invention shown in FIG. 1 will be described below. FIG. 1 is a schematic diagram of a banknote sorting device as a paper sheet sorting device. A banknote storage box 2 serving as a paper sheet separation section located on the upper right side of the machine body 1 is loaded with banknotes 3 in a mixed state regardless of front or back, top or bottom, and denomination. The banknotes 3 are sequentially fed out one by one from the front end by a separation roller 4, and are then held and conveyed by a conveyance path 31 consisting of a belt, rollers, and the like.

It is carried into the discrimination section 5 (first detection means) as a detection means. In the identification department, banknotes 3! ! Judgments are made regarding the type, front and back, authenticity, skew, and conveyance interval, etc., and genuine notes (
Classified into Q tickets) and other excluded tickets (gomaki). The bank note 3 determined to be a rejected note by the discrimination section 5 is carried out to the conveyance path 32, where it is held and conveyed, and immediately before reaching the first branch point 6a (branch section), a solenoid 4 is activated as shown in FIG.
0 is driven and the gate 20 operates as shown by the solid line, thereby transferring the receiver to the conveyance path 33. and.

The tickets are held and conveyed by this conveyance path 33 and reach the confluence point 7a, where they are piled up in a rejected ticket storage box 8 serving as a second accumulation section. In this way, rejected tickets that may later become abnormal sheets are sent directly to the second stacking section, thereby prohibiting them from being sent to the conveyance path 34 where the front and back reversal section is provided. Next, banknotes that are determined to be genuine and official notes that can be classified by the discrimination section 5 are transferred to a conveyance path 32.
From there, it is held and conveyed along conveyance paths 34 and 36 (first conveyance path) and reaches the confluence point 7b. The bank note 3 determined by the discrimination section 5 to be a genuine note and a counternote is conveyed by the conveyance path 32, 34, and just before reaching the bifurcation point 6b, the solenoid 41 is activated, and the gate 21 is activated as shown by the chain line in FIG. The banknote 3 is guided to the conveyance path 35 (second conveyance path) by the movement as shown in FIG. 18 in the direction perpendicular to
It rotates by 0°, becomes one face ticket, and reaches the confluence point 7b. here.

This is because the conveyance path 35 and the conveyance path 36 have approximately the same length and are securely sandwiched by the belt.

By simply driving both conveyance paths 35 and 36 at a constant speed, even if the front and back tickets are conveyed alternately, the conveyance interval between them will be the same, so that between the branching point 6b and the confluence point 7bL, ,
The feeding intervals of the banknotes 3 in the transfer path become equal, and subsequent processing of the banknotes 3 on the conveyance path becomes easy. The bank note 3 that has reached the confluence point 7b is held and conveyed by the conveyance path 37, and is passed through solenoids 42, 43, 44 according to the denomination determined by the discrimination section 5.
．． 45 is activated, and the gates 22 .
23゜24.25 operates, and the collection box 60, 61゜62 is predetermined for each denomination as the first collection.
．． Predetermined banknotes 3 are stacked and stacked at 63.

The above describes the case where the bank note 3 is normally held and conveyed on the conveyance path after the discrimination section 5, but the banknote 3 determined to be a genuine note by the discrimination section 5 is transferred on the conveyance path after the discrimination section 5. This may be skewed depending on the condition of bank note 3.

A conveyance abnormality may occur in which the feeding interval of banknotes 3 becomes abnormal. Therefore, the terminal end of the conveyance path 37, which constitutes the final stage of the conveyance path, is extended so that the banknotes 3 held and conveyed by the conveyance path 37 can be accumulated in the rejected note storage box 8. Then, the end of the conveyance path 33 and the extended end of the conveyance path 37 meet at the merging point 7a, and the banknotes 3 conveyed by the respective conveyance paths 33 and 37 are accumulated in the rejected note storage box 8. do. Note that the conveyance paths 33 and 37 do not need to merge, and the conveyed banknotes 3 may be independently accumulated in the rejected note storage box 8. In addition, the conveyance path 33.3
7 are configured to meet at their ends, but the end of one conveyance path may also be configured to merge in the middle of the other conveyance path. is configured in this manner, and a detection means (a second detection means) for detecting the conveyance state 1, for example, skew and feeding interval of the banknotes 3 which are pinched and conveyed by the conveyance path 37, is installed before the collection box 60 of the conveyance path 37 is located. A sensor 9 as a means) is installed. Note that the position of the sensor 9 is not limited to this position, and the installation is arbitrary. Optional. In the case of the embodiment, when a conveyance abnormality occurs, the gates 22 of the collection boxes 60, 61, 62, 133,
Since banknotes 3 tend to jam at the 23°24.25 position, the position shown in the figure was set immediately before the first gate.

When the above-mentioned conveyance abnormality occurs, the sensor 9 provided on the conveyance path 37 detects the skew and the interval, and if the skew and interval are conveyed beyond a certain specified value, the gates 22, 23, 2. ;.

25 should not be operated. In this way, the banknotes 3 are eventually conveyed through the conveyance path 37 and piled up in the rejected note accumulation box 8. In this case, by providing a guide 10 at the confluence point 7a as shown in FIG. jams can be further prevented. Reference numeral 11 denotes a guide for smoothly guiding the banknotes 3 into the rejected note collection box 8.

In the above embodiments, a case has been described in which banknotes are classified by denomination, but the detection means detects whether the banknotes are genuine or if they are denominations that should be eliminated. The present invention is also applicable to a system in which banknotes are collected in one stacking section via conveyance paths 34 to 37, and banknotes are accumulated in a second stacking section via conveyance path 33, thereby classifying banknotes only into good or bad. It is possible. Furthermore, it goes without saying that the device of the present invention is not limited to banknotes, but can be applied to paper sheets in general.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the conveyance interval is the same regardless of whether a single sheet is fed in a non-inverted or reversed state, making it easy to handle the sheet.
