Description

  The technology disclosed herein relates to a paper sheet bundling device and an error recovery method for a paper sheet bundling device.

  Patent Document 1 describes a banknote binding apparatus that binds a bundle of banknotes with a tape. This banknote binding apparatus is provided with a turning arm in a binding section for binding banknotes. The swivel arm is configured to wind the tape drawn from the tape reel around the bill. The swivel arm is supported so that its base end is rotatable, and a grip portion for gripping the tip of the tape is provided at its tip. With the gripping part gripping the leading end of the tape, the swivel arm rotates approximately once, so that the tape is wound around the banknote bundle. This bundling operation will be described in more detail. With the gripping portion gripping the tip of the tape, the swivel arm first rotates and waits for approximately a semicircle from the initial position. At this standby position, the tape is arranged in a semicircular arc shape. On the other hand, a predetermined conveyance means conveys the banknotes collected in the stacking part different from the binding part to the binding part, and the banknotes are inserted in the radial direction with respect to the tape having an approximately semicircular arc shape. Thereafter, the swivel arm rotates the remaining semicircle from the standby position, whereby the tape is wound around the banknote bundle.

  Here, the grip portion is configured to open and close like a bowl and to grip the tip of the tape in the thickness direction. The gripping portion is also configured to be opened by the cam mechanism only when the swing arm is located at the initial position, and to remain closed otherwise.

Utility Model Registration No. 25977751

  By the way, various information such as bank name, date, time, banknote denomination, correct bill and non-paying bill type may be printed on the tape wound around the bundle of banknotes. Printing is performed after the tape reel is pulled out and before the tape is wound around a bundle of banknotes.

  Here, for example, the stacking of banknotes in the stacking unit may be defective, or the stacking of banknotes may be collapsed while the banknote bundle is being transported from the stacking unit to the binding unit. Since such an error is an error that should stop the binding operation of banknotes, the banknote binding device stops operating and needs to return from the error state. That is, the operator must perform operations such as opening the housing of the banknote binding device, opening the inside, and taking out the banknote causing the error from the housing.

  When such an error occurs and the bundling operation is stopped, if the tape has already been printed as described above, the tape cannot be used as it is after returning from the error. Therefore, it is necessary to cut the middle of the tape and discard at least the printed portion. In order to recover from the error state, the operator must not only take out the banknote but also pull out and cut the tape and set the tape again.

  However, as described above, the tip of the tape is in a state of being gripped by the gripping portion, and when the swinging arm is in a position other than the initial position (for example, in the standby position), It remains closed. Therefore, the operator puts the hand inside the banknote binding device, opens the gripping part by hand to release the gripping of the tip of the tape, pulls the tape out of the casing, and taps the tape at a predetermined place. Must be cut. As described above, when the bundling operation is stopped due to the occurrence of an error, there is a problem that the restoration work related to the tape becomes complicated. Moreover, when the binding part is located at a deep position in the banknote binding apparatus, the workability is further deteriorated.

  The technology disclosed herein has been made in view of the above points, and the purpose of the technology is to provide a paper sheet bundling apparatus for bundling paper sheets when an error to stop the bundling operation occurs. Furthermore, it is intended to make it possible to easily recover from the error.

  Specifically, the technology disclosed herein is a paper sheet bundling device that binds a paper sheet bundle by winding a tape around it.

  The paper sheet bundling device has a tape supply unit configured to set the tape wound in a reel shape, and a tape transport path extending from the tape supply unit, and is drawn out from the tape supply unit The tape is fed along the tape transport path in the supply direction, and the tape transport section configured to pull back the tape in a direction opposite to the supply direction, and the tape is supplied via the tape transport path. A bundling portion having a grip portion configured to grip the leading end of the tape and configured to wind the tape around the bundle of paper sheets starting from the leading end of the tape gripped by the gripping portion; In a state where the tape is wound around the bundle of paper sheets, the tape is attached at a joint portion that joins the overlapping tapes, and at a portion that is not wound around the bundle of paper sheets. Comprising a cutting unit for cross, and a error detection unit for detecting that an error should stop the unity operation of the paper sheet occurs.

  When the timing at which the error detection unit detects an error is the timing before the tape is joined and the tape is cut, the gripping unit releases the tip of the tape being gripped. In order to cut the middle of the pulled-out tape, the tape transport unit pulls back the tape.

  According to this configuration, the tape pulled out from the tape supply unit is supplied to the binding unit via the tape transport path. In the binding unit, the gripping unit grips the leading end of the tape and winds the tape around the bundle of paper sheets with the leading end of the tape as a starting point. Various configurations can be adopted as the configuration for winding the tape around the paper sheet. The tape wound around the paper sheet is joined by the joining portion and cut by the cutting portion. Thus, the binding of the paper sheets is completed.

  Before such a bundling operation is completed, more specifically, an error at which the error detection unit should stop the bundling operation at a timing before the tape is joined by the joining portion and the tape is cut by the cutting portion. When it is detected that the occurrence has occurred, the gripper opens the tip of the tape, and the tape transport unit pulls back the tape. That is, the tape cannot be pulled back after the tapes are joined or cut. Further, the gripping part opens the tip of the tape, whereby the tape can be pulled back.

  In this way, the tape can be pulled back from the vicinity of the bundling portion, and the tape can be pulled back to a convenient location for the operator to cut the middle of the tape. As a result, the operator can easily perform work for returning from an error relating to the tape.

  The paper sheet bundling device further includes a housing that accommodates at least the bundling portion, the joining portion, the cutting portion, and the tape transport portion, and the housing has an opening / closing portion that can be opened inside. The tape transport unit may pull back the tape until the predetermined position of the tape reaches the position of the opening / closing unit when the error detection unit detects an error.

  In this way, when the opening / closing part is opened and the inside of the housing is opened, the operator can visually recognize a predetermined portion of the pulled-back tape. As a result, the operator can grasp the state of the tape in the casing. The operator can pull out the tape from the housing and cut an appropriate portion of the tape, or can cut an appropriate portion while the tape is placed in the housing.

  The tape transport unit may pull back the tape until the predetermined position of the tape reaches the position of the tape supply unit when the error detection unit detects an error.

  The tape supply unit is configured to be openable to the outside of the casing because the tape wound in a reel shape is set, or is open to the outside of the casing. For this reason, by pulling back the tape until the predetermined position of the tape reaches the position of the tape supply unit, the operator can visually recognize the predetermined position of the pulled-back tape. Thus, as before, the operator can cut an appropriate portion of the tape.

  The paper sheet bundling device further includes a casing that houses at least the tape supply unit, the bundling unit, the joining unit, the cutting unit, and the tape transport unit, and the tape supply unit It is good also as arrange | positioning so that it may open | release outside the said housing | casing facing the upper surface.

  By doing so, the tape supply unit is opened upward in the paper sheet bundling device, so that the operator can easily confirm the predetermined location of the pulled-back tape at the tape supply unit, and the tape can be easily cut. become.

  When the error detection unit detects an error, the tape transport unit may pull back the tape until the leading end of the tape is at a predetermined position closer to the tape supply unit than the bundling unit.

  By pulling back the tape with reference to the leading end of the tape, the tape can be pulled back to an appropriate position. That is, the tape can be pulled back from the vicinity of the bundling portion by pulling back until the leading end of the tape is closer to the tape supply unit than the bundling portion. As a result, the tape can be easily cut.

  The paper sheet bundling device further includes a printing unit disposed in the middle of the tape conveyance path and configured to perform printing on a predetermined range of the tape supplied to the bundling unit, and the tape conveyance unit includes: When the error detection unit detects an error, the tape may be pulled back until the printing end position of the tape becomes a predetermined position on the tape supply unit side with respect to the bundling unit.

  When an error occurs and the bundling operation is stopped, it is necessary to cut and discard the printed portion of the tape. Therefore, by pulling back the tape on the basis of the printing end position of the tape, the tape can be pulled back until the portion to be cut of the tape reaches an appropriate position.

  The bundling portion creates a tape ring of a predetermined size by sending out the tape with the tape transporting portion while the gripping portion grips the leading end of the tape. Then, after positioning the bundle of paper sheets, the tape transport unit may retract the tape to reduce the tape loop and wind the tape around the bundle of paper sheets.

  Since the bundling portion having such a configuration forms a tape loop, a relatively long amount of tape is present in the vicinity of the bundling portion. Accordingly, when an error occurs, the tape is pulled back from the vicinity of the bundling portion, thereby facilitating the work of cutting and discarding the middle of the tape.

  The bundling portion creates a small tape loop by rotating around an axis orthogonal to the tape feeding direction in a state where the gripping portion grips the leading end of the tape, and the tape transporting portion is The tape ring having the predetermined size may be created by increasing the diameter of the small tape ring by feeding out the tape.

  The bundling portion having such a configuration is to feed the tape in a state in which a small tape ring is formed and increase its diameter. Conversely, when the gripping portion releases the tip of the tape and then pulls back the tape, The tape is pulled back smoothly.

  The technology disclosed herein relates to an error recovery method for a paper sheet bundling apparatus that wraps a tape around a bundle of paper sheets.

  The paper sheet bundling device includes a grip portion configured to grip a leading end of the tape pulled out from a tape reel, and the tape is used as a starting point from the front end of the tape gripped by the grip portion. In the state where the tape is wound around the bundle of paper sheets, the overlapping tapes are joined to each other, and the tape is cut at a place where the tape is not wound around the bundle of paper sheets It is configured as follows.

  This method detects that an error that should stop the binding operation of the paper sheets has occurred, and the detection of the error is a timing before both the joining of the tape and the cutting of the tape are performed. The tip of the tape gripped by the gripping part is released, and after releasing the tip of the tape, the tape is pulled back to cut the middle of the tape pulled out from the tape reel.

  As described above, according to the error recovery method of the paper sheet bundling device and the paper sheet bundling device, when an error that should stop the bundling operation occurs, the recovery operation can be easily performed.

Both the first binding stacker 4A and the second binding stacker 4B accumulate the banknotes to be bound. The banknotes accumulated as the banknotes to be bound can be set as appropriate. The banknote to be bound is a predetermined type of banknote. The predetermined type is specified by the denomination, whether it is a correct or non-defective ticket, the front and back of the banknote, the direction of the banknote, whether it is a new or old ticket, and the like. Here, the banknote to be bound is a predetermined denomination (for example, 100 yuan) and a genuine banknote. Here, the banknotes identified as normal banknotes by the identification unit 3 are conveyed as “normal banknotes”, and the banknotes that are not identified as normal banknotes by the identification unit 3 are conveyed as “abnormal banknotes” by skew feeding or double feeding. A banknote in which the state is abnormal is referred to as a “transport abnormal banknote”. For example, one of the conditions for determining whether or not the banknote is normal is whether or not the serial number can be identified. However, it may be determined whether the banknote is normal under different conditions, or another condition may be added to determine whether the banknote is normal. In addition, even if it is a normal banknote, a banknote of a type in which a transport destination (a binding stacker, a non-binding stacker, etc.) is not designated is referred to as “non-designated banknote”. Further, among normal banknotes, a banknote with a relatively small amount of dirt, tears, and the like is referred to as a “correct ticket”, and among normal banknotes, a banknote with a relatively large number of dirt, tears, and the like is referred to as a “damaged ticket”.

At this time, the banknote handling apparatus 100 is installed such that the first side surface 123 of the housing 12 faces the customer. In this state, the second side surface 124 of the housing 12 faces the operator. However, since the banknote handling apparatus 100 is located slightly on the left side of the operator, the customer can also visually recognize the second side surface 124.

  First, an operator receives a banknote in a rose state to be deposited from a customer, and places the banknote on the hopper unit 2. At this time, even if a plurality of types of banknotes are mixed in the banknotes in a rose state, they are placed on the hopper unit 2 without being classified. An operator adjusts the guide part 22 according to the dimension of a banknote. Subsequently, the operator operates the touch panel 17 to start taking in banknotes. Note that when the bill sensor 25 detects the placement of the bill on the hopper unit 2, the bill processing apparatus 100 may automatically start taking in the bill.

  The banknotes placed on the hopper unit 2 are taken into the housing 12 from the take-in port 24 one by one when the take-in roller 23 is operated. The taken banknote is transported by the first transport unit 7 and passes through the identification unit 3. The identification unit 3 acquires the banknote type of the banknote that passes through and notifies the control unit 120 of the banknote type.

  The control part 120 determines the conveyance destination corresponding to a banknote according to the kind of banknote. Specifically, when the banknote is a banknote of a predetermined denomination to be bound and is a correct banknote, the control unit 120 sets the transport destination as the binding stacker 4 (any one of 4A and 4B). When the banknote is a banknote of a predetermined denomination and is a banknote banknote, the control unit 120 sets the transport destination as the first non-binding stacker 5A. When the banknote is a banknote of a denomination other than the predetermined denomination, the control unit 120 sets the transport destination as the second non-binding stacker 5B. When the banknote is a reject banknote, the control unit 120 sets the transport destination as the reject stacker 6.

  The control unit 120 controls the first transport unit 7 so that the banknote is transported to the stacker that is the transport destination. Specifically, the control unit 120 controls the sorting mechanism 73 corresponding to the branch path 72 connected to the stacker as the transport destination so that the bill is guided from the main transport path 71 to the branch path 72. The control unit 120 switches the sorting mechanism 73 when the passage sensor 74 immediately before the branch path 72 detects a bill. Then, the banknote is carried into the stacker.

  The bills conveyed to the bundling stacker 4 are conveyed to one of the two bundling stackers 4. When the number of banknotes stacked on one binding stacker 4 reaches a predetermined number (for example, 100), the subsequent banknotes are conveyed to the other binding stacker 4. Here, it is assumed that the banknote is first conveyed to the first binding stacker 4A. In each first binding stacker 4 </ b> A, when bills are conveyed, the bills are stacked one by one by the rotation of the impeller 42. At this time, when the uppermost banknote on the stage 41 is detected by the second banknote sensor 46, the stage 41 is lowered by a predetermined amount, and the second banknote sensor 46 is not detecting the banknote. Thereafter, when the banknotes are further stacked and the second banknote sensor 46 detects the banknotes, the stage 41 is again lowered by a predetermined amount. By repeating this process, the falling distance of the banknotes falling into the bundling stacker 4 can be kept within a certain range, so that the falling position of the banknotes that fall naturally and the posture when they fall can be made constant.

  When the banknotes accumulated in the first binding stacker 4A reach the number of bindings, the control unit 120 controls the second transport unit 8 to grip the banknotes in the first binding stacker 4A by the gripping unit 81, and to remove the banknotes. It is conveyed to the binding unit 9. Thereafter, the control unit 120 controls the binding unit 9 to bind the banknotes with the tape T.

  When the banknotes stacked on the first binding stacker 4A reach the binding number, the subsequent banknotes are stacked on the second binding stacker 4B. Thereafter, when the banknotes stacked on the second binding stacker 4B reach the binding number, the subsequent banknotes are again stacked on the first binding stacker 4A. By this time, since the banknotes in the first binding stacker 4A have been unloaded, the first binding stacker 4A is empty. Thus, by providing the two binding stackers 4, the binding process can be performed while the banknotes are continuously collected.

  Subsequently, the control unit 120 controls the third transport unit 10 to throw out the bundled banknotes from the outlet 111.

  The banknotes of a predetermined denomination and banknotes are conveyed to the first non-bundling stacker 5A and accumulated in the first non-bundling stacker 5A. Similarly, banknotes of denominations other than the predetermined denomination are conveyed to the second non-bundling stacker 5B and accumulated in the second non-bundling stacker 5B. Reject banknotes are also transported to the reject stacker 6 and accumulated in the reject stacker 6.

  The above process is continued until there are no more banknotes placed on the hopper unit 2. The presence or absence of banknotes in the hopper 2 is detected by the banknote sensor 25.

  When the processing of the banknote placed on the hopper unit 2 is completed, the rejected banknote is taken in and identified again. That is, the operator removes the reject banknote from the reject stacker 6, places it on the hopper unit 2, and takes it in again. Since the reject banknote is a banknote that has not been identified as a normal banknote for some reason, it tries to capture and identify again. Nevertheless, the banknotes identified as reject banknotes are again accumulated in the reject stacker 6. The operator returns the accumulated banknotes to the customer.

  In addition, about the banknote integrated | stacked on the 1st and 2nd non-bundling stackers 5A and 5B, it does not take in again.

  Thus, when the processing of the banknotes placed on the hopper unit 2 and the reprocessing of the rejected banknotes are completed, the same-type bundling process is completed, and the counting and sorting of banknotes to be deposited passed from the customer are completed. On the touch panel 17, the counted amount is displayed. When the operator obtains the approval of the amount from the customer or confirms the coincidence between the amount and the amount described in the payment slip described by the customer, the operator confirms the amount of money with the touch panel 17. When the confirmation operation is performed, the confirmed deposit amount is notified to a higher-level device (not shown), and the deposit process is completed.

  After the depositing process is completed, the operator takes out the bundled banknotes accumulated in the dispensing unit 11, the banknotes accumulated in the bundling stacker 4, and the banknotes accumulated in the non-bundling stacker 5, and puts them in a predetermined storage location. Store.

  By the above processing, a banknote in which a plurality of types of banknotes are mixed and in a loose state is a regular banknote of a predetermined denomination, a banknote banknote of a predetermined denomination, and a banknote of a denomination other than the predetermined denomination, The bills are classified as reject banknotes, and the correct banknotes of a predetermined denomination are in a state of being bound for each bound number.

<Detailed description of processing after integration>
Hereinafter, a process from when the banknotes are accumulated in the bundling stacker 4 to when the banknotes are thrown out to the dispensing unit 11 will be described in detail.

−Compression of banknotes−
FIG. 8 is an explanatory diagram of banknote compression processing in the binding stacker, (A) shows a state immediately after completion of banknote accumulation, and (B) shows a state after completion of banknote compression. In addition, illustration of the 1st banknote sensor 45 is abbreviate | omitted in FIG.

  As shown in FIG. 8A, immediately after the stacking of banknotes is completed in the bundling stacker 4, the stage 41 is positioned relatively downward, and the top banknote among the banknotes B on the stage 41 is the top plate 44. Away from.

  When the accumulation of the bills B is completed, the stage 41 rises and compresses the accumulated bills B with the stage 41 and the top plate 44. As shown in FIG. 8B, the control unit 120 raises the stage 41 to a position where the distance between the stage 41 and the top plate 44 becomes a predetermined value T1. As a result, the banknote B on the stage 41 is compressed to the same thickness as the predetermined value T1. Note that, when the bill B is a new bill or the like, and the thickness of the bill B that is freely dropped and accumulated on the stage 41 does not reach the predetermined value T1, the stage 41 is raised as described above. The bill B is not compressed. The stage 41 and the top plate 44 are an example of a compression unit.

-Transporting banknotes to the bundling section-
When the stacking of banknotes B is completed in the binding stacker 4, the second transport unit 8 transports the banknotes B from the binding stacker 4 to the binding unit 9. In FIG. 9, the figure of the state which the 2nd conveyance part 8 extracted the banknote B from the binding stacker 4 is shown. In FIG. 10, the figure of the state which the 2nd conveyance part 8 conveyed the banknote B to the side of the tape ring L is shown.

  Specifically, when the stacking of the bills B is completed, the second transport unit 8 moves to the binding stacker 4 where the stacking of the bills B is completed, grips the bills B in the binding stacker 4, and binds as shown in FIG. Pull out from the stacker 4. Here, it is assumed that the accumulation of the bills B is completed in the first binding stacker 4A. And the holding unit 81 of the 2nd conveyance part 8 hold | grips the banknote B in 4 A of 1st binding stackers. The stage 41 and the top plate 44 of the bundling stacker 4 are provided with a gap through which the gripping unit 81 can be inserted. Therefore, the gripping unit 81 can grip the banknote B that is sandwiched between the stage 41 and the top plate 44. The gripping unit 81 sandwiches the banknote B compressed by the stage 41 and the top plate 44 from the stacking direction and further compresses it. That is, the thickness T2 of the bill B gripped by the gripping unit 81 is thinner than the thickness T1 of the bill B compressed by the stage 41 and the top plate 44. The stage 41 descends after the gripping unit 81 holds the bill B. The second transport unit 8 extracts the gripped banknote B from the first binding stacker 4A in the first horizontal direction. At this time, the 2nd conveyance part 8 moves the banknote B to a 1st horizontal direction to the predetermined | prescribed 1st position (position shown in FIG. 9). This 1st position corresponds with the 1st horizontal direction position at the time of conveying bill B mentioned below into large tape ring L2.

  Then, the 2nd conveyance part 8 moves the banknote B to an up-down direction to the predetermined | prescribed 2nd position, as shown in FIG. This 2nd position is a position which conveys bill B into large tape ring L2. In the second position, when viewed in the longitudinal direction of the bill B, the bill B is located near the center of the large tape ring L2.

−Creation of tape ring−
The control unit 120 creates the tape loop L while the second transport unit 8 transports the banknote B from the binding stacker 4 to the second position. FIG. 11 shows a state where the tape gripping portion 921 grips the leading end portion of the tape T. FIG. 12 shows a state in which the tape gripping portion 921 starts to rotate while gripping the tip end portion of the tape T. FIG. 13 shows a state where the tape gripping portion 921 has created the small tape ring L1. FIG. 14 shows a state in which the creation of the large tape ring L2 has been completed.

  First, the feed roller pair 920 pulls back the tape T until the first tape sensor 9210 detects the leading end of the tape T. When the leading end of the tape T is detected, the feed roller pair 920 feeds the tape T. At this time, the tape gripping portion 921 stands by in a state where a gap is left between the movable portion 923 and the base plate 922a and the tape T sent from the feed roller pair 920 enters the gap. When the leading end of the tape T enters between the movable portion 923 and the base plate 922a, the rotary shaft 924 is driven to rotate, and the leading end of the tape T is moved between the movable portion 923 and the base plate 922a as shown in FIG. Hold it. The movable portion 923 is locked in a state where the tip portion of the tape T is held together with the base plate 922a. The tip of the tape T is held by the tape holding portion 921 in a substantially horizontal state.

  The printing unit 97 prints on the tape T in parallel with the feeding by the feeding roller pair 920. In this way, printing is performed within a predetermined printing range on the tape T as shown in FIG.

  Next, the tape gripping portion 921 starts rotating with the tip end portion of the tape T gripped as shown in FIG. At this time, the delivery of the tape T by the delivery roller pair 920 continues. The tape gripping portion 921 rotates so as to move the tip of the tape T downward, that is, counterclockwise in FIG.

  When the tape gripping portion 921 rotates substantially once, a tape loop L is created as shown in FIG. Thus, the tape loop L created by the tape gripping portion 921 rotating substantially once is referred to as “small tape loop L1”. The tip of the tape T gripped by the tape gripping portion 921 is positioned above the small tape ring L1, and the small tape ring L1 is created below the tape gripping portion 921. The small tape ring L1 is formed at a position lower than the feed roller pair 920.

  When the small tape ring L1 is formed, the tape gripping portion 921 stops rotating, while the feeding of the tape T by the feeding roller pair 920 is continued. As a result, the small tape ring L1 gradually increases. Here, the tip end portion of the tape T gripped by the tape gripping portion 921 is positioned above the small tape ring L1, and the tape T from the feed roller pair 920 is supplied from the top of the small tape ring L1, so that the small tape The ring L1 swells downward. Since the guide portion 925 is disposed below the tape grip portion 921, the tape ring L eventually comes into contact with the guide portion 925, and the shape of the tape ring L is defined by the guide portion 925. When the feed amount of the tape T from the feed roller pair 920 finally reaches a predetermined amount, a tape ring L formed in a substantially rectangular shape is created by the guide portion 925 as shown in FIG. This tape ring L is referred to as “large tape ring L2”. The large tape ring L2 is in contact with the lower guide portion 926, the first side guide portion 927, and the second side guide portion 928, and is formed in a substantially rectangular shape. In addition, the large tape ring L2 is in contact with the first to fourth corner guide portions 929a to 929d, thereby forming a rectangular shape with curved corner portions.

  The control unit 120 creates the large tape ring L2 when the second tape sensor 9211 detects the tape T when the amount of the tape T fed from the pair of feed rollers 920 reaches the predetermined amount. Is detected. The control unit 120 obtains the feed amount of the tape T based on the drive amount of the stepping motor of the feed roller pair 920 after the first tape sensor 9210 detects the leading end of the tape T. When the second tape sensor 9211 does not detect the tape T even though the feeding amount of the tape T from the feeding roller pair 920 reaches the predetermined amount, the control unit 120 determines that a part of the tape ring L is There is a possibility that the tape ring L is not bent into an appropriate shape along the guide portion 925 (that is, the large tape ring L2). Therefore, when the second tape sensor 9211 does not detect the tape T when the feed amount of the tape T from the feed roller pair 920 reaches the predetermined amount, the control unit 120 moves the tape T by a predetermined pullback amount. After pulling back, the tape T is fed again until the total delivery amount reaches the predetermined amount. Then, the control unit 120 confirms whether or not the second tape sensor 9211 detects the tape T. When the second tape sensor 9211 does not detect the tape T, the control unit 120 repeats the above-described pull-back and feed-out of the tape T and confirmation of the tape detection.

  The second tape sensor 9211 is configured to detect the tape T guided by the fourth corner guide portion 929d. That is, the second tape sensor 9211 detects the presence or absence of the tape T at a predetermined position above the banknote B when the banknote B is conveyed into the large tape loop L2. If a part of the tape ring L bends inward, there is a high possibility that the upper part of the tape ring L bends due to its own weight. That is, by arranging the second tape sensor 9211 at the aforementioned position, it is possible to accurately detect the bending of the tape ring L.

  The large tape ring L2 is created in parallel with the process in which the second transport unit 8 transports the bills B from the binding stacker 4 to the binding unit 9 as shown in FIGS. Normally (that is, when the large tape loop L2 is created by feeding the tape T once), the creation of the large tape loop L2 is completed when the bill B is conveyed to the second position.

-Tape winding-
FIG. 15 is an operation explanatory view of each part until the bill B is conveyed to the large tape ring L2 and the tape T is wound around the bill B when viewed in the thickness direction of the bill B. In FIG. 15, (A) is a state immediately before the banknote B is conveyed to the large tape ring L2, (B) is a state where the banknote B is conveyed to the large tape ring L2, and (C) is The tape T is wrapped around the banknote B. In FIG. 16, the state of the guide part 925 when the clamp part 94 presses the banknote B is shown.

  As described above, the second transport unit 8 transports the bill B to the second position (see FIG. 15A) and then moves the bill B in the second horizontal direction as shown in FIGS. And enter the large tape loop L2. The 2nd conveyance part 8 moves the banknote B to the predetermined | prescribed 3rd position of a 2nd horizontal direction, as shown to FIG. 15 (B). In the example shown in the figure, the third position is a position where the tape T coincides with the center of the bill B in the longitudinal direction in the second horizontal direction. However, the third position is appropriately changed according to the size of the bill B and the designated binding position.

  After the bill B is conveyed to the third position, the gripping unit 81 re-grips the portion other than the portion to be bundled of the bill (the portion around which the tape T is wound in the subsequent processing), and then the clamp portion 94 has the bill B. Are pressed from both sides in the stacking direction, that is, in the vertical direction. Specifically, the lower clamp portions 943 and 944 of the clamp portion 94 move upward. At this time, the movable upper clamp portion 942 is located at the clamp position. Finally, the lower clamp parts 943 and 944 press the bill B against the upper clamp parts 941 and 942. The upper clamp portions 941 and 942 and the lower clamp portions 943 and 944 sandwich both sides of the bill B in the longitudinal direction of the bill B from above and below. Thus, the banknote B is compressed from above and below by the upper clamp portions 941 and 942 and the lower clamp portions 943 and 944. The lower clamp parts 943 and 944 that rise are stopped at positions where the upper clamp parts 941 and 942 and the lower clamp parts 943 and 944 compress the bill B to a predetermined thickness.

  Further, since the lower clamp portions 943 and 944 are formed integrally with the lower guide portion 926, the lower guide portion 926 also moves upward as the lower clamp portions 943 and 944 are raised. At this time, by driving the tape reel motor 9111 and the tape feed motor 9212 in the return direction, the tape T is pulled back in conjunction with the ascent of the lower guide portion 926. As a result, as shown in FIG. 16, the tape ring L becomes smaller as the lower guide portion 926 rises. In addition, the second side guide portion 928 also rises in conjunction with the rise of the lower guide portion 926. Thereby, the space which can deform | transform the tape ring L is securable. That is, when the rise of the lower guide portion 926 is too fast with respect to the speed at which the tape ring L becomes smaller, the tape ring L is deformed so as to protrude from the guide portion 925. At this time, since the second side guide portion 928 is retracted from the side of the tape ring L, the tape ring L may swell toward the space where the second side guide portion 928 was originally located. it can. Thereby, it is possible to prevent the tape T from being bent.

  Here, a third abutting portion 942c is provided between the first abutting portion 942a and the second abutting portion 942b of the movable upper clamp portion 942, and the third abutting portion 942c includes the first and second abutting portions 942c. It is located at a position lower than the two contact portions 942a and 942b. In addition, the base portion 922 (that is, the base plate 922a) of the tape gripping portion 921 is disposed between the first contact portion 941a and the second contact portion 941b of the fixed upper clamp portion 941, and the base portion 922 is The first and second contact portions 941a and 941b are located at lower positions. On the other hand, in the lower clamp portions 943 and 944, the first clamp portion 943a and the second contact portion 943b are disposed downward, and the first clamp portion 944a and the second contact portion 944b are disposed downward. A recessed space is formed. Therefore, the bill B pressed by the clamp portion 94 has a shape in which a substantially central portion in the short direction is recessed downward.

  The raising of the lower guide part 926 stops with the raising of the lower clamp parts 943, 944. On the other hand, the return of the tape T by the tape reel motor 9111 and the tape feed motor 9212 is continued even after the lower guide 926 stops moving up. Finally, the tape T is wound around the banknote B as shown in FIG. Here, as described above, the position of the tape T in the width direction is regulated by the lower guide portion 926 until just before being wound around the bill B. Therefore, the tape T is accurately wound around the planned binding portion of the banknotes.

-Joining, cutting and stamping of tape-
Subsequently, the heater 95 joins the tapes T, and the cutter 96 cuts the tapes T. In addition, the stamp portion 98 stamps the tape T. In FIG. 17, explanatory drawing of joining of a tape T, a cutting | disconnection, and a stamp is shown.

  When the winding of the tape T around the bill B is completed, the heater 95 and the cutter 96 descend together. At this time, the first and second tape pressers 991 and 992 are also lowered together with the heater 95 and the cutter 96.

  Thereby, as shown in FIG. 17, first, the first tape press 991 is fitted into the first concave groove 922c of the base portion 922, and the tape T is sandwiched between the bottom wall of the first concave groove 922c. At the same time, the second tape press 992 clamps the tape T with the movable portion 923. At this time, welding by the heater 95 and cutting by the cutter 96 are not performed.

  Subsequently, although not shown in the drawing, the heater 95 sandwiches a portion where the tip of the tape T and the tape T that has made a round overlap with the base portion 922 of the tape grip portion 921. Specifically, the heater 95 holds the tape T at a portion of the base portion 922 between the first concave groove 922c and the second concave groove 922d. The heater 95 welds the overlapping tapes T by heat.

  Further, the stamp portion 98 stamps the tape T in parallel with the welding by the heater 95 and the cutting by the cutter 96. The stamp part 98 is raised together with the lower guide part 926 and is located immediately below the bill B when the tape T is welded and cut. After the tape T is pulled back by the delivery roller pair 920 and the tape T is wound around the bill B, the stamping unit 98 raises the stamp 981. The stamp 981 abuts on the tape T wound around the banknote B and stamps on the tape T.

  Here, since the stamp portion 98 is configured integrally with the lower guide portion 926 that regulates the position in the width direction of the tape T, the stamp 981 is positioned with respect to the tape T. Specifically, the tape T passes through the through hole 926d of the bottom wall 926b of the lower guide portion 926 and is stamped on the tape T between the side walls 926a and 926a. Since the position of the tape T wound around the lower surface of the banknote B in the tape width direction is regulated by the side walls 926a and 926a, the tape T is placed at the point where the stamp 981 rises through the space between the side walls 926a and 926a. positioned. Thus, the stamp 981 is stamped without protruding from the tape T.

  Further, in the longitudinal direction of the tape T, even if the character or code printed by the printing unit 97 is located at the portion where the stamp 981 is imprinted, the portion where the stamp 981 is imprinted and the portion where the printing portion 97 is printed Is shifted in the tape width direction, the printing by the stamp 981 and the printing by the printing unit 97 do not overlap.

-Banknote discharge-
The bound banknotes B bound by the tape T are transported to the dispensing unit 11 by the second transport unit 8 and the third transport unit 10. That is, although detailed illustration is omitted, when the joining, cutting, and stamping of the tape T are completed, the gripping unit 81 grips the bundled bills B. Subsequently, the lower clamp portions 943 and 944 are lowered, and the pressing by the clamp portion 94 is released. In addition, the movable upper clamp portion 942 rises. Thereafter, the second transport unit 8 transports the bundled banknotes B in the second horizontal direction, and transports the banknotes by a predetermined amount to the side opposite to when the banknotes are transported to the large tape ring L2.

  Next, the holding unit 81 releases the holding of the bundled banknote B. Instead, the third transport unit 10 grips the bundled banknote B. Thus, the third transport unit 10 transports the bundled banknotes B toward the dispensing unit 11 in the first horizontal direction. Finally, the bundled banknotes B are pushed out to the dispensing unit 11 by the third transport unit 10.

  The bundled banknote pushed out to the dispensing unit 11 is dispensed to the outside of the housing 12 through the dispensing unit 11.

<Case of bill processing device housing>
The bill processing apparatus 100 configured as described above has a function of guiding an operator to a work location when performing operations such as maintenance and collection of accumulated bills. Examples of maintenance include eliminating paper jams and tape T jams, replacing consumable parts such as ink ribbons in the printing unit 97, and refilling the stamping unit 98 with ink. Examples of banknote collection include collection of banknotes from the binding stacker 4, collection of banknotes from the non-binding stacker 5, collection of banknotes from the reject stacker 6, and the like. Further, as will be described later, a return operation when an error that should stop the binding operation of banknotes due to a banknote stacking failure or stacking failure can be given as an example of maintenance.

  In the banknote processing apparatus 100, some parts of the housing | casing 12 are comprised so that opening and closing is possible, and it is comprised so that the maintenance inside the banknote processing apparatus 100 can be performed.

  Specifically, as shown in FIG. 1, a lower cover 131 is provided in a substantially lower half of the second side surface 124 of the housing 12. The lower cover 131 is provided with the second outlet 53 of the non-binding stacker 5 and the touch panel 17. The lower cover 131 is configured to be rotatable about an axis extending in the vertical direction at a ridge portion between the third side surface 125 and the second side surface 124 facing the first side surface 123. By opening the lower cover 131, the first processing unit 126 is exposed.

  A bundling portion cover 132 is provided on approximately half of the upper surface 121 on the first side surface 123 side and approximately upper half of the second side surface 124 and also on the first side surface 123 side. The binding unit cover 132 is configured to be slidable toward the first side surface 123. The binding unit 9 is exposed by sliding the binding unit cover 132.

  A reel cover 133 is provided on a portion of the upper surface 121 on the third side surface 125 side. The reel cover 133 is configured to be rotatable around an axis extending in the horizontal direction at a ridge between the upper surface 121 and the third side surface 125. By opening the reel cover 133, the tape reel 911 is exposed.

<Return method when an error occurs>
As shown in FIG. 8 and the like, the stacking failure is such that the banknotes are misaligned and stacked when the banknotes are stacked in the binding stacker 4, and the binding stacker 4 binds as shown in FIGS. When the stacking collapse occurs such that the stacking of the banknotes B is broken while the banknote B is being transported to the section 9, the binding operation of the banknotes cannot be continued as it is, and the binding operation must be stopped. It should be noted that such errors due to poor integration can be detected by various sensors.

  When the error which should stop binding operation generate | occur | produces, the control part 120 stops the banknote processing apparatus 100. FIG. Then, the operator is prompted to recover from the error. Specifically, by displaying on the touch panel 17, the bill causing the error is taken out from the housing 12 of the bill processing apparatus 100. While referring to the display content of the touch panel 17, the operator opens the binding unit cover 132 and exposes the vicinity of the binding unit 9, thereby taking out the banknotes from the housing 12.

  When the bundling operation is stopped due to the occurrence of an error and printing has been performed on the tape T that was performed prior to the bundling operation, the print location on the tape T should be used for the next bundling operation. It is necessary to dispose of the part. The operator must discard the predetermined portion of the tape T as well as take out the banknote as a return operation when an error occurs.

  The banknote handling apparatus 100 is configured to pull back the tape T from the viewpoint of facilitating a return operation relating to the tape T when an error occurs. Specifically, when the timing at which the occurrence of the error is detected is the timing before the tape T is wrapped around the banknote and joined, and before the tape is cut, the control unit 120 first sets the tape gripping portion 921. Open and release the tip of the tape T that has been gripped. As described above, the tape gripper 921 can be switched between the open state and the closed state by rotationally driving the rotary shaft 924 with a motor. Note that when the occurrence of an error is detected and the tape gripper 921 is not gripping the tip of the tape T, the tape gripper 921 remains open. Further, when the joining of the tape T and the cutting of the tape T have already been performed, the tape T described later cannot be pulled back.

  Next, the control unit 120 drives the tape reel motor 9111 and the tape feed motor 9212 to pull the tape T back to the tape reel 911 side. Since the leading end of the tape T is released, the tape T can be smoothly pulled back by driving the tape reel motor 9111 and the tape feed motor 9212 in the returning direction. Further, as described above, the tape ring creating unit 92 of the bundling unit 9 creates the small tape ring L1 by rotating the tape gripping part 921 once, and then sends out the tape T to enlarge the tape ring. A large tape loop L2 is used. Therefore, as apparent from FIGS. 11 to 14, no bending or the like occurs in the middle of the tape T, which also makes the tape T to be pulled back smoothly.

  The tape reel motor 9111 and the tape feed motor 9212 continue to pull back the tape T until the leading end of the tape T reaches the tape reel 911. In this way, all the tape T pulled out from the tape reel 911 is once rewound onto the tape reel 911. As described above, since the tape feed amount is controlled during the production of the tape loop L, the length of the tape T pulled out from the tape reel 911 is known at the time of detecting the error. The control unit 120 performs pull-back control of the tape T based on the tape length T.

  Then, when all the tape T is pulled back to the tape reel 911, the control unit 120 opens a reel cover 133 through the touch panel 17, and displays a display prompting the operator to cut and discard unnecessary portions of the tape T. Do. The operator sees this display, opens the reel cover 133, and pulls the tip of the tape T out of the housing 12. Since the tape reel 911 faces the upper surface of the housing 12 and opens upward, it is easy to work. The operator cuts the tape T at least at the printing end portion so that the printing portion on the leading end side of the tape T can be discarded.

  When the cutting of the tape T is completed, the tape T is set again. For example, the same work as the tape setting work performed when the tape reel 911 is replaced with a new one (for example, the tip of the tape T is sandwiched between a pair of drive rollers) may be performed.

  In this way, when all the return operations from the error are completed, the operator inputs the return completion through the operation of the touch panel 17, for example. Instead of inputting the return completion, it is also possible to detect that all of the binding unit collar 132 and the reel cover 133 that have been opened are closed, and the detection signal may be used as an input for the return completion. Further, the completion of restoration by the operator and the fact that all the covers are closed may be used as the completion of restoration. In response to the completion signal, the control unit 120 resumes the operation of the banknote handling apparatus 100.

  As described above, in the banknote processing apparatus 100 having the above-described configuration, when an error to stop the binding operation occurs, the tape gripping unit 921 releases the gripping of the tape T, and the tape reel motor 9111 and the tape feed motor 9212. Pulls back the tape T. As a result, the tape T is pulled back from the bundling portion 9 and finally is pulled back to the tape reel 911. As a result, the operator can easily cut and discard unnecessary portions on the front end side of the tape. That is, the workability of the return work of the operator is improved.

  In particular, the bundling portion 9 having the above-described configuration is configured to create the large tape loop L2, and the length of the tape T existing near the bundling portion 9 when the bundling operation is stopped due to the occurrence of an error. May be relatively long. In such a case, pulling back the tape T and pulling the tape T back from the vicinity of the bundling portion 9 greatly improves the operator's workability.

  Here, in the above configuration, the tape T is pulled back until the leading end of the tape T reaches the tape reel 911. However, the present invention is not limited to this, and the leading end of the tape T is, for example, a predetermined position on the tape transport path. The tape T may be pulled back until it becomes. The predetermined position here may be a position that is released to the outside of the housing 12 when the binding unit cover 132 is opened, for example. By doing so, the operator can visually recognize the front end of the tape T when the binding unit cover 132 is opened. Since the state of the tape T in the housing 12 can be grasped, the operator pulls out the tape T from the housing 12 and cuts a predetermined portion of the tape T, or places the tape T in the housing 12. The predetermined part of the tape T can be cut or left as it is. That is, the amount of pulling back the tape T can be set as appropriate.

  In the above configuration, the pull-back is controlled with reference to the leading end of the tape T. However, since an unnecessary part in the tape T is a printing part, the printing end part in the tape T is used as a reference. The pull back of the tape T may be controlled. Specifically, the tape T may be pulled back until the printing end position on the tape T reaches the tape reel 911. Further, as described above, the tape T is pulled back until the printing end position on the tape T reaches a predetermined position in the tape transport path (for example, a position where the tape T is released to the outside of the housing 12 when the binding unit cover 132 is opened). May be performed. Even with these configurations, the operator can easily perform an operation of cutting and discarding unnecessary portions of the tape T.

  As described above, the technique disclosed herein is applied to the bundling portion 9 configured to insert the banknote B into the large tape ring L2 and wind the tape T around the banknote after the large tape ring L2 is created. In addition, the present invention can be applied to a bundling portion having a configuration other than this. For example, as described in Patent Document 1 described above, the tape gripping portion that grips the tip of the tape can be applied to a bundling portion that is configured to wind the tape around a banknote by rotating the tape by a turning arm. It is. However, the tape gripping portion needs to be configured to be able to release the tip of the tape at an arbitrary position.

  Further, the technology disclosed herein can be widely applied not only to the banknote processing apparatus 100 but also widely to a paper sheet binding apparatus that binds paper sheets.
