Description

  The present invention detects an out-of-synchronization detection of a take-out timing for taking out paper sheets such as banknotes, checks, gift certificates, and other securities and a stacking timing for collecting the taken-out paper sheets by rotating a stacking impeller. The present invention relates to a paper sheet processing apparatus including means.

  A paper sheet processing apparatus that processes paper sheets takes out the paper sheets that are input in a stacked state one by one by a paper sheet take-out device such as a take-out roller, and conveys the paper sheets to a subsequent paper sheet discriminating apparatus. For example, when the paper sheet transported in this way passes through a paper sheet discrimination device provided on the transport path, it is true (whether it is a real paper sheet or a fake paper sheet), and Loss (whether it is a reflowable genuine paper sheet or a non-recyclable paper sheet) is detected, and a plurality of sorting gates provided on the conveyance path are switched based on the detection result, It is transported to a predetermined transport destination such as a paper sheet stacking device, a paper sheet cutting device, and an exclusion ticket stacking device for processing.

  The paper sheet stacking apparatus takes in the paper sheets distributed in this way and sorts and stacks them in the primary stacking chamber. As a result of this accumulation, when a predetermined number (for example, 100 sheets) is reached, the discharge port (shutter) of the primary accumulation chamber is opened, and the cassette corresponding to the primary accumulation chamber is pressed and accumulated by the pushing plate. Alternatively, the accumulated paper sheets are sealed with a paper band.

  Paper sheet cutting devices cut paper sheets that have been in circulation for a long period of time, or paper sheets that are cut, torn, graffiti, taped, etc., as non-performing paper sheets (hereinafter referred to as non-performing paper). And store it in the storage box.

  The rejection ticket stacking apparatus stacks paper sheets that have been determined as fake paper sheets (hereinafter referred to as fake tickets) by the indistinguishable paper sheets or the paper sheet determination apparatus in the rejection ticket stacking cassette.

An accumulation method using an accumulation impeller is known as an accumulation apparatus such as the paper sheet accumulation apparatus or the exclusion ticket accumulation apparatus. It is suitable as a method to reduce the conveyance speed by absorbing the kinetic energy of paper sheets that are conveyed at high speed, when paper sheets that are weak are conveyed and accumulated at high speed, such as paper sheet processing equipment. Often used for. In this case, it is necessary to synchronize the take-out roller for taking out the paper sheets and the accumulation impeller, and the take-out roller and the rotation shaft of the accumulation impeller are physically connected by a timing belt for synchronization. (For example, refer to Patent Document 1).
JP 2001-163500 A (page 3-4, FIG. 1)

  However, since synchronization is achieved by physically connecting the take-out roller and the stacking impellers of a plurality of paper sheet stacking apparatuses, for example, the timing belt teeth that connect the take-out roller and the stacking impeller When the jump occurs, the take-out timing by the take-out roller and the accumulation timing of the accumulation impeller are not synchronized, and there is a problem that the accumulation impeller cannot be normally accumulated. In addition, whether or not the take-out timing and the accumulation timing of the accumulation impeller are synchronized cannot be known unless paper sheets are actually taken out, conveyed, and accumulated, and paper sheets that cannot be accumulated are generated.

  The present invention has been made to solve the above-mentioned problem. When the takeout timing of each sheet and the accumulation timing of the accumulation impeller are checked, and the synchronization between the two is not within a predetermined value, the synchronization is lost. It is an object of the present invention to provide a paper sheet processing apparatus that notifies a device abnormality by a detection means.

In order to achieve the above-mentioned object, the invention described in claim 1 is to detect a take- out roller that takes out one sheet of paper fed in batches every time it rotates, and a take-out rotation of the take- out roller. Yes and the lead roller detection means for detecting once every one rotation, a conveying means for conveying the paper sheet taken out by the take-out roller, a rotary shaft that rotates linked with the take-out roller and the timing belt Te And a plurality of blades around the rotating shaft, receiving the paper sheets to be conveyed between the blades and the blades, and accumulating in the stacking box while rotating in conjunction with the rotating shaft A wheel, an impeller detecting means for detecting the center of the blade of the integrated impeller, and an allowable range time set after a predetermined time from the moment when the take-out roller detecting means detects the rotation of the take-out roller. The impeller When the known device detects the blade, characterized by comprising a control section for determining that synchronization is of the take-out roller and the integrated impeller.

  According to the present invention, the take-out timing for each sheet and the accumulation timing of the accumulation impeller are checked, and when the synchronization between the two is not within a predetermined value, the device abnormality is notified by the out-of-synchronization detection means. I can do it.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of a paper sheet processing apparatus 1 according to an embodiment of the present invention. FIG. 2 is a front view showing a main part of the paper sheet stacking apparatus 30. FIG. 3 is a timing chart for explaining the sheet take-out timing and the synchronization of the integrated impeller detection sensor.

  First, the configuration of the paper sheet processing apparatus 1 will be described with reference to FIG. The paper sheet processing apparatus 1 determines whether a paper sheet P such as a banknote is genuine (true or fake) or correct (whether it can be redistributed or non-recyclable), The correct ticket is classified and collected in the paper sheet stacking devices 30A to 33A according to the type of the paper sheet P, and the damaged paper is cut by the paper sheet cutting device 60, and the cut pieces are collected in a storage box (not shown). It is a device to do.

  The paper sheet processing apparatus 1 is provided with a supply unit 10 that collectively feeds the stacked paper sheets P. The paper sheets P stacked on the supply unit 10 are taken out one by one at regular intervals by the take-out roller 10A, and are supplied to the transport path (transport means) 20. The take-out roller 10A takes out one sheet of paper P every rotation. The conveyance path 20 includes conveyance rollers (not shown) and a conveyance belt (not shown), and conveys the paper sheet P from the upstream in the conveyance direction to the downstream.

  Further, a take-out roller detection sensor (take-out roller detection means) SC10 for detecting the take-out rotation of the take-out roller 10A is provided. Accordingly, the take-out roller detection sensor SC10 is a sensor that becomes dark once every time the take-out roller 10A rotates once.

  In this manner, the paper sheet P supplied from the supply unit 10 by the take-out roller 10A is determined by the paper sheet determination unit 50. The paper sheet discriminating unit 50 detects and discriminates the physical characteristics of the paper sheet P, and includes a plurality of paper sheet discriminating devices 52A to 56. Is provided. In addition, the paper sheet stacking devices 30 to 33 that stack the paper sheets P determined to be genuine based on the determination results of the paper sheet determining devices 52A to 56, and the paper sheets P determined to be non-payable A paper sheet cutting device 60 for cutting, and an exclusion ticket stacking device 40 for stacking counterfeit or exclusion tickets are provided.

  The take-out detection unit 51 detects the take-out state of the paper sheet P supplied from the supply unit 10 and notifies the control unit 2 of the detection result. If the detection result of this removal state is, for example, when multiple sheets are picked up or the conveyance pitch is clogged, troubles such as being unable to be distributed by the sorting gate that is conveyed and processed downstream in the conveyance direction are likely to occur. Notify the control unit 2. The control unit 2 receives the notification of the take-out abnormality and rotates the sorting gate G40 that sorts the transport direction of the paper sheet P to the left to transport the paper sheet P along the transport path 21 and eliminate it. It is accumulated in the ticket accumulation unit 41. The paper sheets P accumulated in the rejection ticket accumulation unit 41 can be supplied again.

  The rejection ticket stacking device 40 stacks the paper sheets P that have been removed by the paper sheet discrimination device 50, and includes a stacking impeller 40A and a rejection ticket cassette 40B. Then, the paper sheets P conveyed along the conveyance path 22 are received by the accumulation impeller 40A and accumulated in the reject ticket cassette 40B.

  The paper sheet discrimination devices 52 </ b> A to 52 </ b> B have a paper sheet P ticket type discrimination or damage discrimination function. For the ticket type discrimination, when the paper sheet P is a Japanese banknote, a denomination consisting of 1,000 yen, 2,000 yen, 5,000 yen, and 10,000 yen and a conveyance state (upright / inverted, front / back) are discriminated. In addition, the discrimination as to whether the paper is correct or not is discriminated.

  The paper sheet discriminating device 53 has a function of detecting the shape of the paper sheet P, detects the length, width, hole, tear, etc. of the paper sheet P and notifies the control unit 2 of the detection result. When the length and width of the paper sheet P exceed the set value of the set ticket type, it becomes an exclusion ticket. Further, if the hole, tear, cut, etc. of the paper sheet P exceed the set value, it becomes a non-use ticket.

  The paper sheet discriminating devices 54A and 54B have a magnetic detection function for the paper sheet P, detect the magnetic material amount of the paper sheet P, and notify the control unit 2 of the detection result. When the amount of magnetic material of the paper sheet P exceeds a set value, or when a predetermined amount of magnetic material does not exist at a predetermined position of the paper sheet, it becomes a rejection ticket.

  The paper sheet discriminating devices 54C and 54D have a fluorescence detection function for the paper sheet P, detect the amount of phosphor of the paper sheet P, and notify the control unit 2 of the detection result. When the phosphor of the paper sheet P exceeds a set value, or when a predetermined amount of the phosphor does not exist at a predetermined location of the paper sheet, it becomes an exclusion ticket.

  The paper sheet discrimination device 55 has a function of detecting the thickness of the paper sheet P, detects the thickness of the paper sheet P, and notifies the control unit 2 of the detection result. If the thickness of the paper sheet P exceeds the set value, it becomes an exclusion ticket.

  The paper sheet discriminating device 56 has a tape sticking detection function and detects a tape stuck to the paper sheet P. If the tape sticking size is within the set value, it becomes a non-paid ticket, and if it exceeds the set value, it becomes a rejected ticket.

  As a result of the processing of the paper sheet discriminating devices 52A to 56, the correct ticket is supplied to the paper sheet stacking devices 30 to 33, the lost ticket is supplied to the paper sheet cutting device 60, and the rejected ticket is the rejected ticket stacking device 40. To be supplied.

  Since the paper sheet stacking devices 30 to 33 are configured in the same manner, the paper sheet stacking device 30 will be described here. The paper sheet stacking devices 31 to 33 are different from the paper sheet stacking device 30. Give an explanation.

  In the paper sheet stacking device 30, the first 100 sheets P of paper sheets P that have been determined as genuine bills as a result of the processing of the paper sheet determining devices 52A to 56 are stacked. At this time, the sorting gate G30 is rotated to the right, and the paper sheet P is transported through the transport path 22 to the first stacking chamber (stacker) of the paper sheet stacking device 30 including the stacking impeller 30A. Accumulated. With the passage of 100 sheets, the sorting gate G30 is rotated to the left side to prevent the sheets P from being continuously accumulated, and the sorting gate G31 is rotated to the right side to continuously convey the 101th and subsequent sheets. The correct paper sheet P is conveyed to the stacking unit 31. The 100 sheets of correct paper sheets P collected in the stack of the paper sheet stacking device 30 are stacked in a second stacking chamber (cassette) and then sealed with a paper strip (not shown). Similarly, when the correct number of sheets collected in the stacker of the stacking unit 31 reaches 100, the sorting gate G31 is rotated to the left side to prevent the sheets from being continuously stacked and the sorting gate G30 is turned on. Rotate to the right and stack the next 100 sheets in the stacker of the sheet stacking device 30.

  The paper sheet stacking devices 32 and 33 are used for stacking different ticket types than those processed by the paper sheet stacking devices 30 and 31. Further, the paper sheets sealed with paper strips every 100 sheets are conveyed to the left by the conveyor 70 and stored in the strap stacker 71.

  Next, the paper sheet stacking apparatuses 30 to 33 will be described with reference to FIG. Since the paper sheet stacking devices 30 to 33 are all configured similarly as described above, the paper sheet stacking device 30 will be mainly described here. FIG. 2 is a diagram illustrating a paper sheet stacking apparatus 30 according to an embodiment of the present invention. The paper sheet stacking device 30 has a rotating shaft 30G that is connected to a take-out roller 10A and a timing belt (not shown) and rotates, and an integrated impeller 30A having a plurality of blades around the rotating shaft 30G. Is provided. This accumulation impeller 30A accumulates the paper sheets P conveyed while rotating in conjunction with the rotation of the take-out roller 10A in the accumulation cabinet 30F.

  FIG. 2A is a front view of the paper sheet stacking apparatus 30 and shows a state in which the paper sheets P are stacked in the stacking box 30F above the shutters 30B and 30B. FIG. 2B shows a state in which the number of sheets P stacked in the stacker 30F has reached a predetermined number (for example, 100) and is stacked on the stackers below the shutters 30B and 30B.

  The paper sheet stacking apparatus 30 is provided with a transport path 22 for guiding the transport path 20 to the stacking impeller 30A by the transport gate G30.

  In the integrated impeller 30A, the blades of the integrated impeller 30A are detected by the integrated impeller detection sensor SC30, and in accordance with the discharge timing of the paper sheets P discharged from the transport path 22, The rotational position and speed of the integrated impeller 30 </ b> A are set so as to capture the paper sheet P at the approximate center between the blades and the blades. Further, the take-out roller 10A of the supply unit 10 described above is controlled so as to take out one sheet of paper in one rotation. The integrated impeller 30A connected by the take-out roller 10A and a timing bell (not shown) is driven and rotated in accordance with this rotation cycle. By this rotation, the next paper sheet P is taken in at the approximate center of the next blade and the blade. In this way, the accumulation operation is performed.

  The paper sheets P taken into the accumulation impeller 30A naturally fall in accordance with the rotation of the accumulation impeller 30A, and are accumulated on the shutter 4 provided at the bottom of the accumulation cabinet (first accumulation means) 30F. (See FIG. 2A).

  The shutter 4 is composed of two plate-like bodies and is provided so as to be openable and closable in a direction orthogonal to the stacking direction of the paper sheets P. In the embodiment, two plate-like bodies provided so as to intersect at the approximate center can be opened and closed simultaneously.

  When a predetermined number of sheets are accumulated on the shutter 4, for example, when it is full (100 sheets), the fullness is detected by a fullness detection sensor (detection means, not shown). As a result of this full detection, two plate-like bodies (hereinafter referred to as shutters) are opened, and the accumulated paper sheets P fall on the backup plate 30E provided in the cassette (second accumulating means) 30D. And accumulated. The paper sheets P accumulated in this way are pressed by the push-in plate 5 that contacts the uppermost paper sheet surface of the paper sheets P (see FIG. 2B).

  The paper sheets P accumulated in the cassette 30D in this way are sealed using a paper band (not shown) by the next sealing device (not shown).

  The take-out roller 10A, the other integrated impellers 31A to 33A, and the integrated impeller 40A of the rejection ticket accumulating device 40 are similarly connected by a timing belt so as to be synchronized.

  Next, the out-of-synchronization detection means for detecting the synchronization between the take-out timing of the paper sheet P and the integration timing by the integration impeller detection sensors SC30 to SC33 will be described with reference to FIG.

  The take-out roller detection sensor SC10 is a sensor that becomes dark once every time the take-out roller 10A rotates once. On the other hand, the impeller detection sensors SC30 to SC33 are sensors that detect the center of the blade, and are sensors that darken once every time one blade blocks the sensor.

  The moment when the take-out roller detection sensor SC10 becomes dark (t1 in FIG. 3 (A)) after the transport roller for transporting the paper sheet rotates and the paper sheet P can be transported, and the blade The instants when the vehicle detection sensors SC30 to SC33 become dark (t2 in FIG. 3B, t3 in FIG. 3C, t4 in FIG. 3D, and t5 in FIG. 3C) are detected. That is, whether or not the impeller detection sensors SC30 to SC33 become dark during an allowable range time T2 set after the elapse of a predetermined time T1 (elapsed time) from the moment (t1) when the take-out roller detection sensor SC10 becomes dark. Is detected.

  As a result of this detection, the impeller detection sensors SC30, SC31, and SC33 are detected within the allowable range time T2. In this case, it is determined that the take-out roller 10A and the integrated impellers 30A, 31A, and 33A are synchronized.

  On the other hand, the impeller detection sensor SC32 is detected outside the allowable range time T2. In this case, it is determined that the take-out roller 10A and the integrated impeller 32A are out of synchronization. As a result of this determination, if the synchronization is lost, the controller 2 notifies the device abnormality. When a device abnormality is notified, it is displayed on an operation unit (not shown) and the conveyance path is stopped. Further, the take-out of the take-out roller 10A is stopped, and the rotation of the integrated impellers 30A to 33A that are driven in synchronization therewith stops.
