Description

  The present invention relates to a paper sheet binding device that is applied to, for example, a banknote processing machine and binds a predetermined number of banknotes.

  In the banknote handling machine, a plurality of banknotes are placed in a stacked state on the placement section, and the placed banknotes are taken and transported one by one, and the denomination, authenticity, front / back direction, etc. are inspected. The banknotes are sorted and discharged into a plurality of discharge sections based on the determination result, or a predetermined number of banknotes that have been inspected are stacked in the stacking section, and then the stacked banknotes are conveyed to a binding section and bound by a binding band. There is what to process (for example, refer to Patent Document 1).

By the way, in the binding unit, the stacked banknotes S are received on the receiving table 100 as shown in FIG. At this time, the band 103 is wound and bound after being bent by pressing the central portion of the upper surface of the stacked banknote S by the pressing protrusion 101a of the upper clamper 101.
JP-A-8-235406

 However, in the past, since the pressing protrusion 101a of the upper clamper 101 is fixedly attached, even if the stacked banknote S is a firm and weak circulation ticket, it is also a firm and rigid government seal. Also, the amount of bending at the time of clamping the stacked banknotes was the same.

 For this reason, in the case of a circulation ticket, there is a possibility that the banding force is weakened and the band is pulled out, and in the case of a government ticket, there is a possibility that the banding force is too strong and the banknote is damaged.

  The present invention has been made by paying attention to the above circumstances, and the object of the present invention is to provide a paper sheet that can adjust the amount of bending at the time of clamping according to the stiffness and rigidity of the stacked paper sheet. It is to provide a processing apparatus.

  In order to solve the above-mentioned problems, the invention described in claim 1 includes a fixed clamper and a movable clamper movable in a direction of moving toward and away from the fixed clamper, and an accumulated paper sheet is formed by the fixed clamper and the movable clamper. Clamper means for bending by clamping the sheet, and bundling means for winding and binding the bundled paper sheets bent by the clamper means, and the movable clamper clamps the stacked paper sheets Sometimes, it has a pressing protrusion that presses and curls the stacked paper sheets toward the fixed clamper, and the pressing protrusion is attached to the movable clamper via a spring material.

  According to the present invention, regardless of the stiffness and rigidity of the accumulated paper sheets, the paper sheets can be bound with a constant bundling force, and it is possible to reliably prevent the binding material from coming off or damaging the paper sheets. .

  On the lower side of the placing portion 2, take-in rollers 7a and 7b for taking in the banknotes P are arranged. A supply roller 8 is provided on the banknote take-in side of the take-in rollers 7a and 7b, and a separation roller 9 for separating the banknotes one by one is rolled on the upper surface of the supply roller 8. The banknotes P separated by the separation roller 9 are conveyed along the first conveyance path 11. An identification unit 12 for identifying the denomination, front / back, authenticity, etc. of the banknote P is provided in the middle of the first transport path 11.

  Second and third transport paths 14 and 15 are connected to the downstream side of the first transport path 11 in the banknote transport direction via a switching gate 13. The 2nd conveyance path 14 conveys the banknote P to the 1st thru | or 3rd discharge parts 3a-3c mentioned above. The first and second switching gates 17 and 18 are disposed in the middle of the second transport path 14, and the bills P are moved from the first to the second by the switching operation of the first and second switching gates 17 and 18. It is selectively conveyed to the 3rd discharge parts 3a-3c. Discharge roller pairs 20a to 20c for discharging the banknotes P are disposed on the lower side of the first to third discharge portions 3a to 3c.

  On the other hand, a front / back reversing mechanism 22 is connected to the downstream side of the third transport path 15 in the bill transport direction. The banknotes whose front and back surfaces are aligned by the front / back reversing mechanism 22 are transported to the stacking unit 26 via the fourth transport path 24 and stacked. A predetermined number of banknotes P, for example 100, are stacked on the stacking unit 26.

  A transport mechanism 28 for transporting the stacked banknotes discharged from the stacking unit 26 to the binding unit 30 is provided below the stacking unit 26. The transport mechanism 28 includes a transport belt 44 that runs across a plurality of rollers 43, and the stacked banknotes are placed on the top surface of the transport belt 44 and transported.

  The bundling unit 30 includes a bundling mechanism 45 that wraps and bundles a band as a bundling material around the stacked banknotes conveyed to the receiving position by the conveyance belt 44, a band supply mechanism 39 that supplies the band to the bundling mechanism 45, A printing mechanism 40 that prints information on a band supplied by the band supply mechanism 39 is provided.

  The band supply mechanism 39 is a supply reel 37 for feeding out the heat-sealable band 36, a supply route 38 for supplying the band fed out from the supply reel 37, and a cutter for cutting a band fed by a predetermined amount along the supply route 38. 34.

 The print mechanism 40 includes a print head 41 and a platen roller 42 that are arranged to face each other via a supply route 38 of the band 36. The print head 41 displays information such as a bank branch name, processing date, and serial number to the band 36. It is designed to print.

  FIG. 3 is a block diagram showing the bundling mechanism 45 described above.

  The bundling mechanism 45 includes a receiving base 47 that receives the stacked banknotes that are transported to the receiving position 46 by the transport belt 44, a clamper mechanism 48 that serves as a clamper that clamps and curves the stacked banknotes received by the receiving base 47, Band winding mechanisms 50 and 50 as binding means for winding and binding the stacked banknotes clamped by the clamper mechanism 48, and a heater 52 for heating and welding the bands wound by the band winding mechanisms 50 and 50 , And a chute 53 that pushes and discharges the stacked banknotes with the band welded from the receiving position 46.

 The clamper mechanism 48 has a lower clamper 55 as a fixed clamper and an upper clamper 56 as a movable clamper. The lower clamper 55 is formed in a V shape so as to protrude downward. A positioning plate 58 is integrally formed on one end of the lower clamper 55 so as to stand vertically. The lower clamper 55 serves as a guide portion that guides the leading end side of the supplied band upward and raises the leading end side of the stacked banknotes conveyed by a predetermined amount to abut the positioning plate 58. A guide plate 59 is provided.

 The upper clamper 56 is attached to the rotating end side of the rotating plate 61. The rotation plate 61 is rotated in the vertical direction by the rotation of the drive shaft 62 of the drive motor, so that the upper clamper 56 is moved in a direction in which the upper clamper 56 contacts and separates from the lower clamper 55. A pressing protrusion 56 a is attached to the lower surface of the upper clamper 56 via a leaf spring 57 as a spring material. The leaf spring 57 is fixed to the upper clamper 56 at one end and attached to the upper clamper 56 at a predetermined angle so that the other end is separated from the upper clamper 56 by a predetermined distance. The pressing protrusion 56 a is attached to the other end side of the leaf spring 57.

 As shown in FIGS. 9 and 10, the pressing protrusion 56 a of the upper clamper 56 is curved so as to protrude downward in a substantially U shape by pushing down the center of the upper surface of the stacked banknote S received by the receiving base 47. It is like that.

 Incidentally, the accumulated banknotes include a circulation ticket and a government seal, FIG. 9 shows a state where the circulation ticket is curved, and FIG. 10 shows a state where the government ticket is curved. Since the distribution ticket shown in FIG. 9 is weak and rigid, when the distribution ticket is pressed by the pressing protrusion 56a of the upper clamper 56, the elastic deformation of the leaf spring 57 is small and the distribution curve is curved. Can be increased. Since the official seal shown in FIG. 10 is strong and rigid, when the official seal is pressed by the pressing protrusion 56a of the upper clamper 56, the elastic deformation of the leaf spring 57 is large, and the official seal is large. The amount of bending can be reduced.

 As shown in FIG. 3, the band winding mechanism 50, 50 is a first bending member 64 that bends the leading end side of the band along the upper surface of the stacked banknote, and the upper surface of the stacked banknote by bending the rear end side of the band. The second bending member 65 is provided so as to overlap the front end side of the belt along the portion. The first bending member 64 is operated by a solenoid (not shown), and the second bending member 65 is operated by a drive motor (not shown).

  The cradle 47 is provided so as to be movable up and down, and is lowered from the receiving position 46 by a predetermined amount when the stacked bills are clamped by the clamper mechanism 48.

  In the vicinity of the cradle 47, a push-up guide 67 is provided as a push-up means. The push-up guide 67 is disposed corresponding to the rear end portion of the stacked banknotes, and is connected to the cradle 47 via a link mechanism 68. The push-up guide 67 moves up and down so as to oppose via the link mechanism 68 based on the up-and-down movement of the cradle 47. That is, when the cradle 47 is lowered, the push-up guide 67 is raised to push up the rear end side in the transport direction of the stacked banknotes to restrict the sag, and when the cradle 47 is raised and returned to the receiving position 46, the push-up guide 67 descends and returns to the standby position.

  Next, the processing operation of the above banknote sorter will be described.

  First, the mixed denomination banknotes P are placed in a stacked state on the placement portion 2 of the apparatus main body 1, and the count classification processing mode or the bundling processing mode is set by the operation portion 4. From this state, the take-in rollers 7a and 7b are rotationally driven. Thereby, the banknote P is taken in, and the banknote P is separated and supplied one by one by the rotation of the supply roller 8 and the separation roller 9. The banknote P is sent to the identification unit 12 via the first transport path 11 and identified.

  For example, when the counting / sorting processing mode is set by the operation unit 4, the identified banknote is conveyed toward the first to third discharge units 3 a to 3 c via the second conveyance path 14. The When the identified banknote is, for example, a thousand yen ticket, the first sorting gate 17 moves to the first discharge roller pair 20a, and the first discharge roller pair 20a rotates to rotate the first discharge gate 20a. It is discharged to the discharge unit 3a. When the identified banknote is, for example, a 10,000 yen bill, it is sent to the second discharge roller pair 20b by the operation of the second sorting gate 18, and the second discharge roller pair 20b rotates to rotate the second discharge roller pair 20b. It is discharged to the discharge unit 3b. When the identified banknote is, for example, an unidentifiable banknote such as a double banknote, a chained banknote, a fake banknote, or a denomination banknote other than the classified denomination banknote, it is sent to the third discharge roller pair 20c. 3 is discharged to the third discharge portion 3c by the rotation of the discharge roller pair 20c.

  On the other hand, when the bundling processing mode is set by the operation unit 4, if the denomination of the banknotes to be bound is designated in advance, the banknote of the designated denomination is transferred to the third transport path 15 via the switching gate 13. To the front / back reversing mechanism 22. The banknotes sent to the front / back reversing mechanism 22 are sent to the stacking unit 26 via the fourth transport path 24 after being aligned on one surface.

  At this time, banknotes other than the designated denomination are discharged to the first to third discharge units 3a to 3c in the same manner as in the counting and sorting process mode.

  When a predetermined number (for example, 100) of banknotes, such as circulation tickets, are stacked on the stacking unit 26, they are transferred from the stacking unit 26 onto the transport belt 44 as shown in FIG. The transferred stacked banknotes S are transported toward the binding unit 30 as shown in FIG. At this time, the leading end side of the stacked banknotes S is guided along the guide plate 59 and lifted upward by a predetermined amount, and is brought into contact with the positioning plate 58 and aligned. At this time, the band 36 is supplied from the supply reel 37, and the band 36 is fed together with the stacked banknotes S and guided upward along the guide plate 59. When the band 36 is sent out for a predetermined length, the leading end side is detected by the detection sensor 70, and the feeding of the band 36 is stopped.

 After that, as shown in FIG. 5A, the upper clamper 56 is rotated downward and the stacked banknotes S are pushed downward by the pressing protrusion 56a to bend. The curved stacked banknote S is a circulation ticket, and its stiffness and rigidity are weak. Therefore, the amount of elastic deformation upward of the leaf spring 57 is small, and the stacked banknote S is largely pushed down to increase the curved amount. After this bending, the band 36 is cut by the cutter 34.

 Further, when the stacked banknotes S are pushed down, the cradle 47 is lowered and the push-up guide 67 is raised via the link mechanism 68. As the push-up guide 67 rises, the rear end side Sa in the transport direction of the stacked banknotes S is pushed up, and the drooping is prevented.

  After that, as shown in FIG. 5B, the first bending member 64 is operated by excitation of a solenoid (not shown) to bend the front end side of the band 36 along the upper surface portion of the upper clamper 56, and then As shown in FIG. 6A, the drive motor (not shown) is operated to operate the second bending member 65 so that the rear end side of the band 36 is bent along the upper surface of the upper clamper 56. It is superimposed on the tip end side of the band 36 that has already been bent.

  After the both ends of the band 36 are overlapped in this way, the heater 52 is lowered as shown in FIG. 6B to heat and weld the overlapping ends of the band 36. As a result, the stacked banknotes are bound by the band 36 to form a banknote bundle. After the band 36 is welded, as shown in FIG. 7A, the heater 52 is raised and returned to the standby position, and the first and second bent members 64 and 65 return to the standby position.

  After that, as shown in FIG. 7B, the upper clamper 56 is slightly raised to advance the chute 53, and the banknote bundle S is released. This released banknote bundle S is stored in a storage unit (not shown). After the banknote bundle S is released, the upper clamper 56 is raised and returned to the standby position as shown in FIG. 8, and the chute 53 is retracted and returned to the standby position. Further, the cradle 47 is raised to return to the receiving position 46, and the push-up guide 67 is lowered to return to the standby position. Thereafter, the stacking operation of stacked banknotes is repeated in the same manner.

   Next, a case where a predetermined number (for example, 100) of banknotes stacked on the stacking unit 26 is not a circulation ticket but a government seal is described.

 In this case, it is transferred onto the conveyor belt 44 in the same manner as described above, and is transported toward the binding unit 30 by the traveling of the conveyor belt 44 and sent onto the cradle 47. Next, the upper clamper 56 is rotated downward and the stacked banknotes S are pushed downward and curved by the pressing protrusion 56a. At this time, since the government seal is strong and rigid, the amount of elastic deformation upward of the leaf spring 57 is large as shown in FIG. 10, and the stacked banknotes S are not pushed down so much and the amount of bending is small. It becomes. From this state, the belt 36 is wound and bound in the same manner as the circulation ticket described above.

  As described above, according to this embodiment, since the pressing protrusion 56a is attached to the upper clamper 56 via the leaf spring 57, the bending amount is adjusted according to the stiffness and rigidity of the stacked banknote S. can do.

 Therefore, in the case of a circulation ticket having a low stiffness, the band 36 can be wound and bundled with a large bending amount, and in the case of a government seal ticket having a strong stiffness, the bending amount can be reduced. 36 can be wound and bound.

 Therefore, it is possible to adjust the reaction force of the curved stacked banknote S to return to a flat state so that the reaction force is equal between the case of the circulation ticket and the case of the government seal, and the optimum binding force can be obtained.
