  However, a binding tape having an adhesive layer is expensive and expensive. Moreover, if a heater is used, power consumption will increase. Furthermore, after the power is turned on, it takes time for the heater to reach a temperature suitable for predetermined thermal bonding, and there is an inconvenience that the bundling operation cannot be performed immediately when desired.

  Accordingly, an object of the present invention is to provide a paper sheet binding machine that can reduce cost and power consumption and is easy to use.

  In order to achieve the above object, according to a first aspect of the present invention, there is provided a paper sheet bundling in which a bundling tape is wound around an accumulated paper sheet in which loose paper sheets are accumulated and an overlapping portion of the bundling tape is joined. And a crimping joining mechanism for biting an overlapping portion of the binding tape and forming an uneven crimping portion on the overlapping portion.

  According to the first aspect, since the pressure bonding mechanism bites the overlapping portion of the binding tape to form the uneven pressure bonding portion in the overlapping portion, there is no need to provide an adhesive layer on the binding tape, and the binding tape Cost can be reduced. Further, since it is not necessary to use a heater for heating the adhesive layer, power consumption can be suppressed. In addition, the bundling operation can be performed immediately after the power is turned on.

  According to a second aspect of the present invention, in the first aspect, the pressure bonding mechanism includes a pair of sandwiching members that sandwich the stacked paper sheets, and one sandwiching member opposite to the other sandwiching member. A first crimping tooth formed on the surface, a crimping member provided on the opposite side of the other clamping member of the one clamping member, and a surface on the one clamping member side of the crimping member And the second pressure-bonding teeth bite the overlapping portion of the binding tape.

  According to the second aspect, since the crimping joining mechanism bites the overlapping portion of the binding tape between the first crimping tooth and the second crimping tooth, the concave and convex crimping is applied to the overlapping portion of the binding tape with a simple structure. The part can be formed. In addition, since the first crimping tooth is formed on the surface of one of the pair of holding members that holds the stacked paper sheets on the side opposite to the other holding member, the stacked paper sheets are clamped. One of the clamping members can be used as a component of the pressure bonding mechanism. Therefore, the number of parts and cost can be reduced.

  According to a third aspect of the present invention, in the second aspect, the crimping member is movable toward the one clamping member.

  According to the third aspect, the crimping member formed with the second crimping teeth is movable toward one clamping member of the pair of clamping members that clamp the stacked paper sheets. The configuration on the member side can be simplified.

  According to a fourth aspect of the present invention, in the second or third aspect, the one clamping member can be pressed toward the pressure-bonding member.

  According to the fourth aspect, since one clamping member can be pressed toward the pressure-bonding member, the overlapping portion of the binding tape can be press-bonded with a stronger force.

The crimping member 81 is provided on the opposite side of the concave sandwiching member 22 of the convex sandwiching member 23 as the cutting crimping unit 58 including the crimping member 81, and is movable toward the convex sandwiching member 23. . 4 and 5, after the support member 72 is located at the cutting position on the most convex sandwiching member 23 side, as shown in FIGS. 4 and 5, the crimping member 81 is most convexly sandwiched with respect to the support member 72 as shown in FIG. 6. When positioned at the operation position on the member 23 side, the cut-side end T2 and the tip-side end T1 of the binding tape T fed from the tape supply mechanism 45 and cut by the cutter 71 are overlapped as shown in FIG. The overlapping portion T3 is joined to the convex clamping member 23 by pressure bonding. The convex clamping member 23, the pressure-bonding member 81, the support member 72, the support member drive unit (not shown), and the pressure-bonding member drive unit (not shown) are bonded to each other by press-bonding the overlapping portion T3 of the binding tape T. A joining mechanism 82 is configured.

  As shown in FIG. 8, a crimping tooth 84 (second crimping tooth) that meshes with the crimping tooth 34 of the convex sandwiching member 23 is formed on the distal end surface 83 of the crimping member 81 on the convex sandwiching member 23 side. . The crimping tooth 84 has a groove portion 86 that is recessed from the distal end surface 83 to the opposite side of the convex sandwiching member 23, and the groove portion 86 is provided side by side in the vertical direction (height direction) at a predetermined interval. Yes. In the crimping tooth 84, between the adjacent groove part 86 and the groove part 86 is a tooth part 85 that protrudes toward the convex sandwiching member 23, and the tooth part 85 has a predetermined interval on the distal end surface 83. Are arranged side by side in the vertical direction (height direction). The tooth portion 85 and the groove portion 86 extend linearly in the front-rear direction.

  The tooth portion 85 of the crimping member 81 is aligned with the groove portion 36 of the convex sandwiching member 23 in the front-rear direction and the vertical direction, and the groove portion 86 of the crimping member 81 is aligned with the tooth portion 35 of the convex sandwiching member 23 and the front-rear direction. And the vertical position is matched. The crimping member 81 and the convex sandwiching member 23 overlap the cut-side end T2 and the tip-side end T1 of the binding tape T fed from the tape supply mechanism 45 and cut by the cutter 71, and sandwich the overlapping portion T3. While the tooth portion 35 enters the groove portion 86 and the tooth portion 85 enters the groove portion 36, the concave and convex crimping portion T4 is formed in the overlapping portion T3 of the paper binding tape T. In other words, the crimping tooth 84 having the toothed portion 85 and the groove portion 86 of the crimping member 81 is engaged with the crimping tooth 34 having the grooved portion 36 and the toothed portion 35 of the convex sandwiching member 23, so that the binding tape T is joined with the crimping tooth 34. The overlapping portion T3 is bitten, and the overlapping portion T3 is press-bonded to form an uneven pressing portion T4.

  The concave and convex crimping portion T4 is formed by the tooth portion 35 and the groove portion 86 at the tip end portion T1 and protrudes toward the cutting side end portion T2, and the tooth portion 35 and the groove portion 86 at the cutting side end. Convex part T6 formed in part T2 and recessed in the opposite side to tip side end part T1, and convex part formed in cutting side end part T2 by tooth part 85 and groove part 36 and projecting to tip side end part T1 side The portion T7, the tooth portion 85, and the groove portion 36 have a concave portion T8 that is formed at the distal end side end portion T1 and is recessed on the opposite side to the cutting side end portion T2.

  The convex portion T5 is fitted and closely attached to the concave portion T6, and the convex portion T7 is fitted and closely attached to the concave portion T8. The convex-concave crimping portion T4 includes a plurality of convex portions T5 and concave portions T6 with a predetermined interval in the length direction of the binding tape T, and the convex portions T5 and concave portions T6 and convex portions adjacent to each other. A convex portion T7 and a concave portion T8 are formed between T5 and the concave portion T6. A plurality of convex portions T7 and concave portions T8 are also formed at predetermined intervals in the length direction of the binding tape T.

  The tooth part 35, the groove part 36, the tooth part 85, and the groove part 86 of the pressure bonding mechanism 82 all extend linearly in the width direction of the binding tape T. Therefore, the convex part T5, the concave part T6, the convex part T7, and the concave part T8 formed by these also extend linearly in the width direction of the binding tape T. In other words, the tooth part 35, the groove part 36, the tooth part 85, and the groove part 86 are all orthogonal to the length direction of the binding tape T, and the convex part T5, the concave part T6, the convex part T7, and the concave part T8. Is also orthogonal to the length direction of the binding tape T.

  Here, the tooth part 35, the groove part 36, the tooth part 85, and the groove part 86 have a length smaller than the width of the binding tape T. As a result, the uneven crimping portion T4 having the convex portion T5, the concave portion T6, the convex portion T7, and the concave portion T8 has an intermediate range slightly narrower than the full width in the width direction of the binding tape T as shown in FIG. Is formed. And the overlap part T3 of the binding tape T will be in the joining state by which peeling with the cutting | disconnection side edge part T2 and the front end side edge part T1 was controlled by forming the uneven | corrugated crimping | compression-bonding part T4.

  As described above, the banknote binding machine 11 winds the binding tape T having a predetermined length by the tape supply mechanism 45 and the cutter 71 around the stacked banknote S in which loose banknotes are stacked. The overlapping portion T3 is bitten, and an uneven crimping portion T4 is formed in the overlapping portion T3 to join the overlapping portion T3. Here, since the crimping bonding mechanism 82 forms an uneven crimping portion T4 in the overlapping portion T3 of the binding tape T and joins the overlapping portion T3, the binding tape T is a paper-made paper having no adhesive layer. Bands will be used, and they are joined at room temperature without being heated. For this reason, the banknote binding machine 11 has no heater.

  When the start button 13 is pressed in a state where an insertion detection sensor (not shown) has detected that the stacked banknotes S have been inserted into the insertion opening 12, the banknote binding machine 11 starts from the state shown in FIG. The tape supply roller 47 sends out the binding tape T. Then, the bundling tape T is fed out while being guided by the pair of insertion guides 46, and the leading end of the binding tape T exits from the tape guide hole 62 of the unit frame 59, and the tape winding guide 41 from the opening 42 of the tape winding guide 41. It passes between 41 and the convex pinching member 23 and moves along the inner surface of the tape winding guide 41. Thereby, as shown in FIG. 3, the binding tape T circulates around the outer sides of the concave sandwiching member 22 and the convex sandwiching member 23 so as to make one round.

  When the binding tape T is supplied for a predetermined time by the tape supply mechanism 45 from the time when the leading end T1 of the binding tape T is detected by the tape sensor 52, the leading end T1 of the binding tape T is cut off from the convex sandwiching member 23. Between the crimping unit 58, it stops before reaching the cut-side end support portion 65 of the wall plate portion 64 as shown in FIG. 3 beyond the tip side end portion pressing portion 63 of the wall plate portion 61.

  After the binding tape T is fed out as described above, the concave sandwiching member 22 is moved in the direction of the convex sandwiching member 23 as shown in FIG. 4, and the stacked banknotes are collected by the concave sandwiching member 22 and the convex sandwiching member 23. S is sandwiched from both sides in the stacking direction. Then, the stacked banknotes S are pinched in a state where the banknotes S are slightly bent into a mountain shape following the shapes of the concave pinching member 22 and the convex pinching member 23. Further, simultaneously with the start of the movement of the concave sandwiching member 22, as shown in FIG. 4, the cutting and crimping unit 58 is moved in the direction of the convex sandwiching member 23 to be positioned at the pressing position, and the distal end side end pressing of the wall plate portion 61 is performed. The front end side end T1 of the binding tape T is pressed by the portion 63 against the back surface 33 of the convex sandwiching member 23 with a strong force.

  In order to securely hold the binding tape T, the distal end side end pressing portion 63 may be shaped so that the binding tape T does not slip easily, or a high friction member may be attached to the distal end side end pressing portion 63. Here, the cut-side end support portion 65 of the opposite wall plate portion 64 pushes the binding tape T and approaches the back surface 33 of the convex sandwiching member 23, but does not press the back surface 33.

  In this state, the stacked banknotes S are sandwiched between the concave sandwiching member 22 and the convex sandwiching member 23, and the binding tape T is pressed against the convex sandwiching member 23 by the front end side end pressing portion 63 of the cutting and crimping unit 58. The tape supply roller 47 of the tape supply mechanism 45 is reversed. Then, as shown in FIG. 5, the leading end T1 of the binding tape T is pressed against the convex sandwiching member 23, while the tape supply mechanism 45 side is more convex than the leading end T1 of the binding tape T. Since it is not pressed against the member 23, the binding tape T is taken up by the tape supply mechanism 45. As a result, as shown in FIG. 4, the ring of the binding tape T along the inner peripheral surface of the tape winding guide 41 is reduced, and the binding tape T eventually becomes concave and convex as shown in FIG. It is wound around the pinching member 23 and the portion on the bundling portion 21 side of the stacked banknotes S sandwiched between them to be in a tension state.

  When a predetermined time has elapsed since the start of winding of the binding tape T and the binding tape T can be regarded as being in a tension state, the tape supply roller 47 is stopped and moved to the retracted position in the cutting and pressing unit 58 at the pressing position. The existing support member 72 and cutter 71 are moved to the cutting position as shown in FIG. Then, the cutter 71 cuts the binding tape T in cooperation with the edge portion of the tape guide hole 62 on the front end side end pressing portion 63 side.

  After cutting the binding tape T, the crimping member 81 is positioned at the operating position with respect to the support member 72. Then, the crimping member 81 moves toward the convex sandwiching member 23 that constitutes the crimping joining mechanism 82 together with the crimping member 81, and the cutting-side end T2 of the binding tape T is overlapped with the leading end T1. As shown in FIG. 5, an overlapping portion T3 is formed, and the overlapping portion T3 is sandwiched between the convex sandwiching member 23. Then, as shown in FIG. 8, the tooth portion 85 of the crimping member 81 enters the groove portion 36 of the convex sandwiching member 23, and the tooth portion 35 of the convex sandwiching member 23 enters the groove portion 86 of the crimping member 81, The crimping tooth 84 having the tooth part 85 and the groove part 86 and the crimping tooth 34 having the tooth part 35 and the groove part 36 bite the overlapping part T3, and form an uneven crimping part T4 in the overlapping part T3. Bind T3.

  Thereafter, the cutter 71, the crimping member 81, and the support member 72 are moved to the retracted position on the opposite side of the convex sandwiching member 23 in the cutting and crimping unit 58, and in parallel with this, the unit frame 59 is also the convex sandwiching member 23. Move to the opposite standby position. In this way, the bundled banknotes S are wound into a bundle of banknotes B wound with the binding tape T. The banknote bundle B produced in this way is pulled at the portion of the stacked banknotes S and pulled out from the concave sandwiching member 22 and the convex sandwiching member 23. In this way, a banknote bundle B obtained by binding the stacked banknotes S with the binding tape T as shown in FIG. 9 is obtained.

  According to the banknote binding machine 11 of the present embodiment described above, the pressure bonding mechanism 82 bites the overlapping portion T3 of the binding tape T and forms the concavo-convex pressure bonding portion T4 in the overlapping portion T3. A paper strip without an adhesive layer on T can be used. Therefore, the cost of the binding tape T can be suppressed. Further, since it is not necessary to use a heater, power consumption can be suppressed. In addition, the bundling operation can be performed immediately after the power is turned on.

  Further, since the pressure bonding mechanism 82 bites the overlapping portion T3 of the binding tape T with the pressure bonding teeth 34 and the pressure bonding teeth 84, the uneven pressure bonding portion T4 is formed in the overlapping portion T3 of the binding tape T with a simple structure. Can do. In addition, a pair of concave sandwiching members 22 that sandwich the stacked banknotes S and a convex sandwiching member 34 are formed on the back surface 33 of one convex sandwiching member 23 opposite to the other concave sandwiching member 22. Therefore, one convex holding member 23 for holding the stacked banknotes S can be used as a component of the pressure bonding mechanism 82. Therefore, the number of parts and cost can be reduced.

  Moreover, since the crimping member 81 in which the crimping tooth 84 is formed is movable toward one convex sandwiching member 23 of the pair of concave sandwiching member 22 and convex sandwiching member 23 that sandwich the stacked banknote S, the convex The position of the pinching member 23 can be fixed, and the configuration on the side of the pair of concave pinching members 22 and the convex pinching member 23 can be simplified.

  The above embodiment can be changed as follows.

  In the above, the position of the convex clamping member 23 is fixed in the banknote binding machine 11, but the present invention is not limited to this, and the convex clamping member 23 may be movable in the same manner as the concave clamping member 22. good.
