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 one by one and conveyed to check the denomination, authenticity, front / back direction, etc. The banknotes are sorted and discharged into a plurality of discharge sections based on the determination result, or a predetermined number of banknotes inspected are stacked in the stacking section, and the stacked banknotes are transported to the binding section and bound by the band. There are some (for example, refer to Patent Document 1).

  In the binding unit, for example, the stacked banknotes S that are conveyed as shown in FIG. 11 are received on the receiving base 100 so that the stacked banknotes can be bound without loosening, and the stacked banknotes S and the movable clamper 101 are received. Is held by the pressing protrusion 101a of the movable clamper 101 so that the central portion of the upper surface of the stacked banknote S is pressed and curved, and the band 103 is wound around the curved stacked banknote S so as to be bound. Yes. The sealing force of the band 103 is determined by the length of the ring.

By the way, the above-described movable clamper 101 is rotated in the vertical direction by the rotation of the drive shaft 106 of the drive motor 105. When the stacked banknote S is curved, the movable clamper 101 is rotated downward from the standby position. The stacked banknotes S are pressed by the pressing protrusion 101a.

Discharge portions 3 a to 3 c are disposed on the upper surface portion of the apparatus main body 1 in parallel in the lateral direction on the front side. The first to third discharge units 3a to 3c discharge banknotes by denomination. For example, a thousand yen bill is discharged to the first discharge portion 3a, a 10,000 yen bill is discharged to the second discharge portion 3b, and a reject bill is discharged to the third discharge portion 3c.

  An operation unit 4 and a display unit 5 are provided on the upper surface of the apparatus main body 1 so as to be located behind the discharge units 3a to 3c. The operation unit 4 selectively sets, for example, a count classification processing mode or a bundling processing mode. In addition, the operation unit 4 is provided with a setting unit 4a. In the bundling processing mode, the strength of the banding force of the stacked banknotes is set to, for example, “strong”, “medium”, “weak” (or “1” “2” and “3”) can be selectively set.

  FIG. 2 schematically shows the internal configuration of the banknote sorter.

  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 binds the stacked banknotes conveyed to the receiving position by the conveyance belt 44 with a band as a bundling material, a band supply mechanism 39 that supplies the band to the bundling mechanism 45, and the band supply A printing mechanism 40 that prints information on a belt supplied by the 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, a processing date, and a 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 accumulated banknotes that are conveyed to the receiving position by the conveyor belt 44, a clamper mechanism 48 that serves as a clamper that clamps and curves the accumulated banknotes received by the receiving base 47, and Band winding mechanisms 50 and 50 as winding means for winding the band around the stacked banknote clamped by the clamper mechanism 48 in a ring shape, and a heater 52 for heating and welding the band wound by the band winding mechanism 50 and 50. And a chute 53 that pushes and discharges the stacked banknotes to which the band is welded from the receiving position.

The heater 52 is mounted so as to be able to swing left and right about the shaft 52a and to be lowered.

  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. In addition, the lower clamper 55 guides the leading end side of the supplied band upward, and as a guide portion that raises the leading end side of the stacked banknotes conveyed by a predetermined amount to contact 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 60 as a drive means, and moves the upper clamper 56 in a direction in which the upper clamper 56 contacts and separates from the lower clamper 55. A pressing projection 56a projects downward from the lower surface portion of the upper clamper 56, and the pressing projection 56a pushes down the central portion of the upper surface of the stacked banknote S so as to be bent so as to project in a substantially U shape. It has become.

  The drive motor 60 is connected to a control unit 63 as control means. The operation unit 4 is connected to the control unit 63, and a setting signal from the setting unit 4a is transmitted. When the setting unit 4 a of the operation unit 4 is selectively set so that the bundling force is “strong”, “medium”, or “weak”, the control unit 63 causes the upper clamper 56 to collect the stacked banknotes S. The push-in position is variably controlled.

  That is, when the banding force is set to “strong” by the setting unit 4a of the operation unit 4, for example, the control unit 63 has the maximum amount of downward rotation of the upper clamper 56 (the upper clamper 56 is in a horizontal state). Rotate so that The band is wound from this state, and in this case, the length of the band of the band is shortened and the band sealing force is strong.

  When the band sealing force is set to “medium” by the setting unit 4a of the operation unit 4, the control unit 63 rotates the upper clamper 56 from a horizontal state upward by a predetermined angle, thereby extending the band. The length of the band of the belt becomes longer than that in the case of the above-mentioned “strong” setting, and the band sealing force is about “medium”.

  Further, when the band sealing force is set to “weak” by the setting unit 4 a of the operation unit 4, the control unit 63 further rotates the upper clamper 56 upward by a predetermined angle from the above-mentioned “medium” setting state. The belt is moved to extend the length of the belt, so that the length of the belt ring becomes longer than that in the above-mentioned “medium” setting, and the band sealing force becomes “weak”.

  The above-described band winding mechanisms 50 and 50 include a first bending member 64 that bends the leading end side of the band along the upper surface of the stacked banknote, and bends the rear end side of the band along the upper surface of the stacked banknote. A second bending member 65 is provided so as to overlap the leading end side of the belt. 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 above-described 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 as a push-up means is provided. The push-up guide 67 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 this stop, the upper clamper 56 is rotated downward. At this time, for example, when the setting unit 4a of the operation unit 4 is set to set the band sealing force to “strong”, As shown in FIG. 5 (a), the upper clamper 56 is rotated downward to the end to be in a horizontal state, and the stacked banknotes S are pushed down and curved by the pressing projections 56a. After this bending, the band 36 is cut by the cutter 34.

  Further, when the stacked banknote S is pressed, 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 S are sealed by the band 36 with a stronger band sealing force (a state in which the length of the ring of the band 36 is short) 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. 7 (b), the upper clamper 56 is slightly raised, the chute 53 is advanced, and the bill is released. This discharged banknote handle is stored in a storage unit (not shown). After the release of the bill, as shown in FIG. 8, the upper clamper 56 is raised to return to the standby position, and the chute 53 is retracted to return 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, the case where the banding force is set to “medium” instead of “strong” by the setting unit 4a of the operation unit 4 will be described.

  In this case, from the state shown in FIG. 6A, that is, from the state in which the upper clamper 56 is rotated to the end to be in a horizontal state and the band 36 is wound around the stacked bill S together with the upper clamper 56. As shown in FIG. 9, the upper clamper 56 is rotated upward by a predetermined angle. Thereby, the length of the ring becomes longer than when the ring of the band 36 is extended and the band sealing force is set to “strong”. Thereafter, similarly to the case shown in FIG. 6B, the heater 52 is lowered and both ends of the band 36 overlapped are heated and welded. At this time, the heater 52 is swung to the left and right in accordance with the inclination of the upper clamper 56, so that the stacked banknotes are sealed by the band 36 with a "medium" band sealing force to form a banknote bundle.

  Further, when the band sealing force is set to “weak” by the setting unit 4a of the operation unit 4, from the state shown in FIG. 9, the upper clamper 56 is further rotated upward by a predetermined angle as shown in FIG. Move. Thereby, the ring | wheel of the band 36 is further extended and lengthened. After that, similarly to the above, the heater 52 is lowered to heat and weld both ends of the band 36, and the stacked banknotes are sealed by the band 36 with a "weak" banding force to form a banknote bundle. .

  In addition, it has been found that the length of the band of the belt spanned around the stacked banknote S has a great influence on the band sealing force with a difference of about 0.3 mm. Therefore, when the band sealing force is set to “medium”, the length of the band of the band is longer than 0.3 mm than when it is set to “strong”, and when it is set to “weak”. Therefore, the return amount of the upper clamper 56 is controlled so that the length of the band of the belt becomes 0.6 mm longer than the case where “strong” is set.

  As described above, according to this embodiment, since the length of the loop of the band 36 spanned over the stacked banknote S can be arbitrarily changed, there is an advantage that a band sealing force desired by the user can be obtained.

  In the above-described embodiment, by rotating the upper clamper 56 in the returning direction, the pushing position of the stacked banknotes S by the upper clamper 56 is varied to vary the ring length of the band 36. Without being limited to this, by rotating the upper clamper 56 in the pushing direction of the stacked banknotes S, the pressing position of the stacked banknotes S by the upper clamper 56 is varied to vary the length of the ring of the band 36. May be.

  Further, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Furthermore, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments.
