Description

  The present invention relates to a paper sheet processing apparatus which is provided in a ticket vending machine installed at a station or the like and used as a safe for taking in inserted banknotes or discharging banknotes as fishing tags.

  Some safes provided in a ticket vending machine have a banknote take-in / return port and a delivery port on one side, and the interior is divided into a stacking chamber and a storage chamber by a movable elongated plate called a separator. . The accumulation chamber is located on the lower side of the storage chamber, and a backup for placing and lifting bills is provided in the accumulation chamber. A feeding roller for feeding out banknotes is provided on the upper side in the storage chamber.

  When purchasing a ticket or the like, a plurality of banknotes are inserted into the ticket vending machine, and the banknotes are once accumulated in a stacking unit in the ticket vending machine. The banknotes accumulated in the stacking unit are separated one by one by the separating and sending unit and sent out to the ticket transport path. The sent banknotes are sent to the identification unit to identify their denominations and the number of sheets is counted. And based on this identification result, banknotes are taken into the collection chamber from the take-in / return port of each safe for each denomination and accumulated.

  When the transaction is confirmed, the banknotes are sent from the stacking chamber to the storage chamber via the separator due to the rise of the backup, and then the backup is lowered to be placed on the separator and stored in the storage chamber.

  On the other hand, the banknotes stored in the storage room are circulated and used as banknotes for unloading from the next customer transaction.

  At the time of paying out, the backup is raised and the stacked banknotes on the separator are pushed up. When the uppermost surface of the pushed up stacked banknote comes into contact with the feeding roller, the rising is stopped and the banknote is fed out by the rotation of the feeding roller. The fed banknotes are stored in the stacking unit via the ticket conveyance path, and after all the fishing cards are stacked in the stacking unit, they are discharged in a lump to complete the fishing operation.

  By the way, if this picking-out operation is repeated, the remaining amount of the stacked banknotes on the backup is reduced, and the fishing bill cannot be paid out. In such a case, reception of large bills is prohibited.

  The remaining amount of the stacked banknotes on the backup is determined as follows.

  That is, in the storage room of the safe, there is a first detection unit that detects the position of the backup that rises during the fishing operation, and a second detection unit that detects that the uppermost surface position of the stacked banknotes has reached the feeding position. It is arranged. The difference between the detection time of the backup position by the first detection unit and the detection time of the stacked banknotes by the second detection unit is calculated by the calculation unit, and the remaining amount of banknotes is measured based on the calculated detection time difference. . Then, a determination unit determines whether or not the measured remaining amount is equal to or less than a predetermined number based on a threshold value. When it is determined that the remaining amount of banknotes is equal to or less than the predetermined number, reception of high-priced banknotes is prohibited (see, for example, Patent Document 1).

By the way, if there is an error in the mounting position of the first or second detection unit or there is a secular change, the detection time difference varies.
JP-A-8-96229

  However, in the past, since the remaining amount of banknotes was determined using a certain threshold, if there is a variation in the difference in detection time, the amount of money that can be withdrawn as a fishing tag is sufficient, but fishing There was a problem that it was judged that the bills were insufficient and reception of high-priced banknotes was prohibited, resulting in a decrease in movable efficiency.

  The present invention has been made paying attention to the above circumstances, and the object of the present invention is to accurately detect the remaining amount of paper sheets even if there is an attachment error or the like in the first and second detection units. An object of the present invention is to provide a paper sheet processing apparatus.

In order to solve the above-mentioned problem, the invention described in claim 1 includes a backup in which paper sheets are placed in a stacked state and lifted along the stacking direction, and a stacked paper sheet raised by the backup. A feeding unit that feeds out from the uppermost paper sheet, a first detection unit that detects the position of the rising backup plate, and a second detection unit that detects the position of the paper sheet that has reached the feeding unit Calculating means for calculating a detection time difference between the first and second detection units, a measuring means for measuring the remaining amount of the paper based on the detection time difference calculated by the calculating means, and the measuring means and discriminating means for discriminating with reference thresholds measured remaining amount to or less than a predetermined amount by said paper said the backup sheet is increased in an empty state where no first detection unit The second Detected by the detecting section calculates the detection time difference, the backup set in advance and the detected time difference and the calculated and compared with a reference time difference empty state, to correct the reference threshold on the basis of the time difference min Correction means.

  According to the present invention, even if there is an attachment error of the first and second detection units or a secular change, the remaining number of sheets can be accurately determined, and the movable efficiency of the apparatus is improved.

The feeding roller 31 is connected to a drive motor 33 via a power transmission system 34 including a belt, a pulley, and the like, and is driven to rotate by the rotation of the drive motor 33. The feeding roller 31 is attached to the tip end side of a detection lever sensor 36 as a second detection unit. The detection lever sensor 36 detects the bill feeding position by rotating based on the feeding roller 31 being pushed up by the upper surface of the stacked bill. That is, the feeding roller 31 and the detection lever sensor 36 are used both as a feeding mechanism and a detection mechanism.

  A separation unit 37 is provided on the bill feeding side of the feeding roller 31. The separation unit 37 includes a feed roller 38 and a separation roller 39 provided on the lower side of the feed roller 38.

  Further, in the storage chamber 21, as shown in FIG. 3, a detection sensor 41 as a first detection unit that detects the position of the backup plate 24 that rises and the presence or absence of banknotes on the backup plate 24 are detected. An empty detection sensor 42 is provided as an empty detection means.

  Next, the processing operation of the banknote processing apparatus configured as described above will be described.

(1) Reception operation When a customer inserts a plurality of banknotes from the insertion / ejection unit 1, the banknotes are once accumulated in the accumulation unit 2. The banknotes stacked in the stacking unit 2 are separated one by one by the separating and sending unit 3 and sent out to the transport path 4. The sent banknotes are sent to the identification unit 5 to identify the denomination and the like and to count the number of sheets. And based on this identification result, a banknote is accumulate | stored in the safe parts 7-12 for every denomination. That is, 1,000 yen is the capture collection room 20 of the thousand yen safe section 7, 5,000 yen is the capture collection room 20 of the 5,000 yen safe section 8, and 10,000 yen is the capture collection room 20 of the 10,000 yen safe section 11. 2,000 yen is accumulated in the 2000 yen safe unit 12.

  When the transaction is confirmed, each banknote is sent from the take-up stacking chamber 20 to the storage chamber 21 for storage. That is, the banknotes accumulated in the take-in accumulation chamber 20 are sent into the storage chamber 21 through the separator 19 as the backup plate 24 rises. Thereafter, the backup plate 24 is lowered and returned to the lower side of the separator 19, whereby the banknotes on the backup plate 24 are received on the separator 19. Thereafter, the banknotes are sequentially fed into the storage chamber 21 and stored in the same manner.

  The identification error ticket that could not be identified by the above-described identification unit 5 is returned to the user after being rejected to the rejection store 9.

  On the other hand, the stored banknote is reused as a banknote for fishing in the next customer's transaction.

(2) Unloading operation In the operation of paying out the change, a necessary number of banknotes are paid out from the respective safe units 7-12. That is, at this time, the stacked banknotes in the storage chamber 21 are pushed up by the rise of the backup plate 24. When the feeding roller 31 is pushed up by the uppermost surface of the stacked banknotes and the detection lever sensor 36 is operated, the ascent of the backup plate 24 is stopped and the banknotes are fed out by the rotation of the feeding roller 31. The fed banknotes are separated and sent out one by one by passing between the delivery roller 38 and the separation roller 39. The banknotes are stored in the stacking unit 2 via the transport path 4, and after all the fishing cards are stacked in the stacking unit 2, they are discharged to the loading / unloading unit 1 in a lump to complete the fishing operation.

  When the above-described fishing operation is repeated, the remaining amount of banknotes in the storage chamber 21 is reduced, and it is determined that the fishing bill is insufficient. If this determination is made, the acceptance of high-value banknotes is prohibited.

  Next, a method for determining the lack of fishing tags will be described.

  At this time, first, the position of the rising backup plate 24 is detected by the detection sensor 41. Next, when the backup plate 24 is raised, the upper surface portion of the stacked banknotes is brought into contact with the feeding roller 31 and pushed up, whereby the detection lever sensor 36 is operated to detect that the upper surface of the stacked banknotes has reached the feeding position. The detection signals of the detection sensor 41 and the detection lever sensor 36 are transmitted to the calculation means 43, and the detection time difference is calculated. Based on the calculated detection time difference, the remaining amount of the bill is measured by the measuring unit 44, and it is determined by the determining unit 45 whether or not the remaining amount of the bill is equal to or less than a predetermined amount based on the reference threshold value. When it is determined that the remaining amount of banknotes is equal to or less than the predetermined amount, it is assumed that there are not enough fishing tags, and reception of high-value banknotes is prohibited.

  By the way, when there is an error in the mounting position of the detection sensor 41 or when the feeding roller 31 is worn, the detection time difference between the detection sensor 41 and the detection lever sensor 36 varies. If the detection time difference varies in this way, even if there are enough fishing tags remaining, it may be determined that there is a lack of fishing tags and the acceptance of high-value banknotes may be prohibited.

  Therefore, in the embodiment of the present invention, the reference threshold value is corrected in consideration of variations in the detection time difference.

  Next, the reference threshold correction operation will be described with reference to FIG.

  When correcting the reference threshold, first, the presence or absence of banknotes on the backup plate 24 is determined by the empty detection sensor 42 at the time of self-diagnosis operation at the time of startup or at the time of completion of the collection operation (step ST1). If it is determined that there is a banknote on the backup plate 24, the process ends without automatic correction (step ST2). If it is determined that there is no banknote, the position of the rising backup plate 24 is detected by the detection sensor 41. Then, the position of the backup plate 24 is detected by the detection lever sensor 36. Then, the time difference of the detection time is calculated by the calculation means 43 (step ST3), and the calculated detection time difference is corrected by the correction means 46 in the reference detection time difference (theoretical value) when the preset backup plate 24 is empty. And the time difference is calculated (step ST4). The calculated time difference is added to or subtracted from the reference threshold value, or the reference threshold value is corrected by linear correction (step ST5). The discriminating means 45 discriminates the remaining amount of banknotes using this corrected threshold value.

  As described above, according to this embodiment, after determining that there is no banknote on the rising backup plate 24, the detection time difference of the backup plate 24 by the detection sensor 41 and the detection lever sensor 36 is calculated, and this calculation is performed. The detected time difference is compared with a reference detection time difference (theoretical value) when the preset backup plate 24 is empty, and the reference threshold value is corrected based on the time difference. Even if there is an attachment error or secular change, the remaining amount of banknotes on the backup plate 24 can be accurately determined. Therefore, unlike the prior art, there is an advantage that the processing efficiency can be improved without interrupting the acceptance of high-priced banknotes even though there is a sufficient number of fishing tags.
