Utility Model Registration No. 2545067

  By the way, in order to reduce the size of the apparatus, there is a limitation due to the layout configuration of each part constituting the apparatus. For example, the direction of the tape surface in the tape supply means and the introduction of the tape for introducing the tape into the bundling means In some cases, the tape surface is arranged in a direction different from the direction of the tape surface. In this case, it is necessary to change the direction of the tape by twisting a part of the tape between the tape supply means and the tape introduction unit. However, if the operator sets the direction in which the tape is twisted incorrectly, The tape may not be introduced into the tape introduction portion in the correct orientation, which may cause a binding failure.

  Accordingly, an object of the present invention is to provide a paper sheet bundling apparatus that can suppress the occurrence of a bundling defect due to a tape setting error.

  In order to achieve the above object, the invention according to claim 1 is directed to a supply unit that supplies tapes that are different from each other, and a folding guide that twists the tape supplied from the supply unit in a predetermined direction and guides it to the introduction unit. And a binding unit for winding the tape introduced into the introduction unit around a binding object to bind the tape, the folding guide unit from the supply unit The first state along the width direction in the tape feeding posture and the second state along the width direction in the tape introduction posture to the introduction portion can be tilted, and in the first state, The tape is twisted in the predetermined direction when the second state is reached from the state where the tape from the supply portion is wound and folded back to the introduction portion side.

  The invention according to claim 2 is the invention according to claim 1, wherein the supply unit includes a set unit that is set in a state where the tape is wound in a roll shape, and the tape that is set in the set unit. A supply guide portion to be guided first, and the supply guide portion between the set portion and the supply guide portion when the set direction of the tape to the set portion is appropriate. When the set direction is not appropriate without interfering with the tape guided by the guide, a restricting member is provided at a position where the tape is guided by the supply guide portion.

  The invention according to claim 3 is the invention according to claim 1 or 2, further comprising a feed mechanism that automatically feeds the leading end portion of the tape introduced into the introduction portion to a predetermined standby position, and the folding guide portion. From the supply section when the folding guide section is in the second state, rather than the path of the tape from the supply section to the introduction section through the folding guide section when the is in the first state The path of the tape to the introduction part through the folding guide part is shorter.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the folding guide portion is screwed to a support shaft that supports the folding guide portion so as to be tiltable. As a result, the second state is closer to the introduction portion than the first state.

  According to the first aspect of the present invention, when the folding guide portion is in the first state along the width direction in the feeding posture of the tape from the supply portion, the tape from the feeding portion remains in the feeding posture without difficulty. When the folding guide portion is tilted to the second state with the tape being wound and folded to the introduction portion side in this way, the tape is automatically determined in a predetermined direction. In addition, the tape is introduced into the introduction portion. Therefore, since the front and back of the tape can be introduced into the introduction portion in a predetermined direction, it is possible to suppress the occurrence of a binding failure due to a setting error of the tape return guide portion.

  According to the invention which concerns on Claim 2, when the setting direction to the set part of a tape is appropriate, the control member provided between the set part and the supply guide part is guided to the supply guide part. If it does not interfere with the tape and the setting direction of the tape in the set part is not appropriate, it interferes with the tape guided by the supply guide part, so that the operator is in the proper direction of setting the tape in the set part. It can be recognized visually. Therefore, it is possible to suppress the occurrence of binding failures due to erroneous mounting of the tape on the set portion.

  According to the invention of claim 3, even if the folding guide portion in the state where the tape from the supply portion is wound and folded back to the introduction portion side is left in the first state, it is introduced into the introduction portion. When the tape is automatically fed by the feed mechanism, the folding guide portion is automatically tilted by the tension of the tape to the second state where the tape path is shorter than the first state. Therefore, it is possible to prevent a problem caused by forgetting to tilt the return guide portion from the first state to the second state.

  According to the invention which concerns on Claim 4, even if the return guide part in the state where the tape from the supply part is wound and turned back to the introduction part side is left in the first state, the tension is generated on the tape. The folding guide part is automatically tilted to the second state closer to the introduction part than the first state by screwing to the support shaft. Therefore, it is possible to prevent a problem caused by forgetting to tilt the return guide portion from the first state to the second state.

The supply unit 12 has a base table 22 arranged substantially horizontally, and a set unit 20 and a supply guide unit 21 are arranged on the base table 22.

  The tape T set in the set portion 20 is wound around a cylindrical core member 25 to form a roll, and the side opposite to the core member 25 is unwound from the roll-shaped portion Ta forming a roll shape and pulled out. And extend outward. The extending portion Tb extending from the roll-shaped portion Ta is along the tangential direction of the roll-shaped portion Ta in a state where tension is generated. In the tape T, one side of the front and back direction is a glue surface t1 on which an adhesive layer for thermal bonding is formed, and the other side of the tape T is a non-glue surface t2 on which such an adhesive layer is not formed. Yes. That is, the tape T is different. The tape T is wound around the core member 25 with the glue surface t1 facing inward in the radial direction and the non-glue surface t2 facing outward in the radial direction.

  The set unit 20 has a circular shape and is provided on the base table 22 so as to be rotatable. The set unit 20 is rotated by being driven by a rewind motor (not shown), and the center of rotation is along a direction perpendicular to the upper surface of the base table 22. The set part 20 supports the core member 25, that is, the roll-shaped part Ta so as to be integrally rotatable by fitting the inner peripheral part of the core member 25 to the outer peripheral part thereof. In this set state, the tape T of the roll-shaped portion Ta has a posture along the vertical direction in which the width direction is orthogonal to the base table 22.

  The supply guide unit 21 includes a fixed shaft 28 that is parallel to the rotation center of the set unit 20, a pulley 29 that is rotatably supported on the fixed shaft 28 at the same height position as the set unit 20, and a pulley 29 and a base base 22. The holding plate 30 is fixed to the fixed shaft 28 and extends so as to face the outer peripheral surface of the pulley 29, and the holding plate 30 is fixed to the opposite side of the base base 22 of the fixed shaft 28. And an upper plate 31 in contact with the free end side.

  The pulley 29 has a main guide portion 33 whose outer surface is a cylindrical surface, and flange portions 34 on both axial sides of the main guide portion 33. The holding plate 30 is formed with a convex portion 35 that is bent so as to protrude toward the pulley 29 at an intermediate portion in the axial direction of the fixed shaft 28, and on the opposite side of the convex portion 35 from the base table 22. An inclined plate portion 36 that is inclined so as to be separated from the fixed shaft 28 as the distance from the base table 22 is increased. In the holding plate 30, the front end surface on the protruding side of the convex portion 35 faces the outer peripheral surface of the main guide portion 33 of the pulley 29 in a close state, and closes to the upper plate 31 in the inclined plate portion 36.

  The extending portion Tb of the tape T drawn from the roll-shaped portion Ta set in the set portion 20 is inserted between the pulley 29 and the holding plate 30 from between the inclined plate portion 36 and the upper plate 31, The main guide portion 33 of the pulley 29 is wound in a predetermined direction in contact with the glue surface t1, and in this state, the portion between the roll-shaped portion Ta of the extending portion Tb and the pulley 29 moves up and down in the width direction. It will be in the state extended in the tangential direction from the roll-shaped part Ta with the attitude | position along the direction. At this time, the holding plate 30 covers the opposite side of the contact portion of the tape T to the pulley 29 from the pulley 29, and the upper plate 31 restricts the tape T from falling off the pulley 29.

  The supply unit 12 is provided with a regulating member 40 that is disposed between the holding plate 30 and the base table 22 and is fixed to the base table 22. The restricting member 40 is mounted on the base table 22 and fixed thereto, and the fixed plate section 41 is connected to the fixed plate section 41 (that is, the upper surface of the base table 22) from the edge of the fixed plate section 41 on the set section 20 side. It has a restricting plate portion 42 erected vertically. In other words, the restricting plate portion 42 is disposed between the set portion 20 and the supply guide portion 21.

  As shown in FIG. 1, the restriction plate portion 42 is set in a state where the tape T is wound around the set portion 20 in an appropriate direction, specifically, when wound around the core member 25 counterclockwise as viewed from above. The roll-shaped portion Ta and the tangential line common to the main guide portion 33 of the pulley 29 (the tangential line on the side where the extending portion Tb is wound around the folded portion 13 in the main guide portion 33). It is formed at a position where it does not interfere regardless of the outer diameter. Further, as shown in FIG. 2, the regulation plate portion 42 is set in a state where the tape T is not properly oriented to the set portion 20, specifically, in a state where the tape T is wound around the core member 25 clockwise as viewed from above. And the tangent line common to the roll-shaped portion Ta and the main guide portion 33 of the pulley 29 (the tangential line on the side where the extended portion Tb is wound around the folded portion 13 in the main guide portion 33). Regardless of the outer diameter of Ta, it is formed at a position where it interferes.

  In other words, when the tape T is set to a new one or the like when the tape T is replaced with a new one, if the setting direction of the tape T to the setting unit 20 is appropriate, the tape T is pulled out from the roll-shaped portion Ta and guided to the supply guide unit 21. If the tape T is not interfered with the tape T and the setting direction of the tape T to the set portion 20 is not appropriate, the position where the tape T is pulled out from the roll-shaped portion Ta and guided to the supply guide portion 21 to interfere with the tape T. In addition, a restricting plate portion 42 of the restricting member 40 is provided. In other words, the supply unit 12 is provided with a restricting member 40 that makes it possible to recognize that the way of routing is incorrect by being a shield for the routing of the tape T. In the direction, the leading end of the tape T is pulled and crosses the pulling tangent in the direction of the supply guide portion 21 that first contacts, and the leading end of the tape T is blocked in the correct mounting direction of the tape T. The part is arranged at a position allowing the drawing without intersecting with the drawing tangent to the supply guide part 21 which is first brought into contact with the feeding guide part 21.

  As shown in FIG. 3, the folded portion 13 includes a bracket 45 fixed to the base base 22, a support member 46 fixed to the bracket 45, a support shaft 47 installed on the support member 46, and a support shaft 47. It has a retractable folding guide shaft 48 (folding guide portion) that is supported, and a tilt regulating member 49 that is fixed to the folding guide shaft 48.

  The support member 46 includes a rectangular bottom plate portion 51 fixed to the bracket 45 so as to be parallel to the base table 22, and a pair of support plate portions 52 and 53 that rise vertically from opposite sides of the bottom plate portion 51. The pair of support plate portions 52 and 53 are open except for the bottom plate portion 51 side in the direction orthogonal to the direction connecting the support plate portions 52 and 53. As shown in FIG. 1, the support member 46 has one support plate portion 52 facing the supply guide portion 21 side, and the other support plate portion 53 positioned on the opposite side of the support plate portion 52 from the supply guide portion 21. It is fixed to the bracket 45 in such a posture.

  As shown in FIG. 3, the support shaft 47 is installed at a central position in the width direction of the support plate portions 52 and 53 in a posture orthogonal to the support plate portions 52 and 53. The folding guide shaft 48 has a cylindrical shape, and one end portion in the axial direction is rotatably supported by the support shaft 47. The folding guide shaft 48 is positioned along the bottom plate portion 51 between the pair of support plate portions 52 and 53 as shown in FIG. 3, or the tip end side is positioned above the bottom plate portion 51 as shown in FIG. 4. The state can be changed by tilting when standing up.

  The tilt regulating member 49 is located at a predetermined position on the upper side opposite to the bottom plate portion 51 when the folding guide shaft 48 is tilted to the opposite side to the set portion 20 shown in FIG. As shown, the substrate portion 54 is fixed with screws 55. The tilt restricting member 49 is formed with a rotation stop 57 that fits into the hole 56 of the folding guide shaft 48 to prevent rotation on one side of the substrate portion 54, and the folding guide shaft 48 on the other end side of the substrate portion 54. A restricting portion 58 is formed on the outer side in the radial direction with an obtuse angle and extending obliquely. The restriction portion 58 is wider than the gap between the support plate portions 52 and 53 of the support member 46.

  The restricting portion 58 has a folding guide shaft 48 that falls to the opposite side to the set portion 20 and is in a sideways state as shown in FIG. 3 along the bottom plate portion 51, and a standing portion shown in FIG. Tilt between the standing state is allowed, and tilting to the opposite side of the above-described sideways state from the standing state is restricted by contacting the support plate portions 52 and 53. The folding guide shaft 48 in the standing state where the restricting portion 58 abuts on the support plate portions 52 and 53 is inclined so as to be slightly closer to the sideways state than the vertical posture perpendicular to the bottom plate portion 51. In this state, the regulating portion 58 has an inclination angle so as to come into contact with the support plate portions 52 and 53 by surface contact. The folding guide shaft 48 in the standing state is slightly inclined with respect to the vertical, so that the folding guide shaft 48 is in a sideways state due to its own weight.

  As shown in FIG. 5, the introduction portion 14 opens toward the folded portion 13 and has an opening shape that is narrow in the vertical direction and wide in the horizontal direction. The introduction part 14 is provided at the upstream end position of the tape supply of the bundling part 61 that winds and bundles the tape T around a plurality of stacked banknotes (binding objects) S. That is, the introduction unit 14 supplies the tape T introduced from the supply unit 12 via the folding unit 13 to the bundling unit 61. From the relationship between winding at the bundling portion 61 and thermal bonding, the tape T from the folded portion 13 is introduced into the introduction portion 14 in a posture in which the width direction is along the horizontal direction as shown in FIG. Moreover, it is necessary to be introduced with the non-glue surface t2 facing up and the glue surface t1 facing down.

  When the folding guide shaft 48 is in the standing state (first state) shown in FIG. 4, the folding guide shaft 48 rises to a position close to the vertical direction and follows the vertical direction. In this standing state, the supply unit 12 shown in FIG. It follows the width direction in the feeding posture of the tape T from the supply guide portion 21 (the posture in which the width direction is aligned in the vertical direction). Further, when the folding guide shaft 48 is in the sideways state (second state) shown in FIG. 1, it takes a posture along the horizontal direction, and in this sideways state, the posture of introducing the tape T into the introduction portion 14 (width). (The posture in which the direction is along the horizontal direction) along the width direction.

  6 to 9 sequentially show the situation when the tape is set by the folding guide shaft 48. When the tape is set, as shown in FIG. 6, when the roll-shaped portion Ta is set in the set portion 20 in an appropriate direction, the extending portion Tb of the tape T is pulled out with the width direction aligned vertically. In this state, the tape T is wound around the pulley 29 in a direction in which the adhesive surface t1 is brought into contact with the main guide portion 33, and then counterclockwise as viewed from above so as to face the folded portion 13. At this time, the portion of the tape T that is wound around the pulley 29 also extends in the vertical direction, and this posture is the feeding posture of the tape T from the supply unit 12 toward the folding unit 13. Therefore, as shown in FIG. 6, when the folding guide shaft 48 of the folding unit 13 is in the standing state, the folding guide shaft 48 is along the width direction in the feeding posture of the tape T from the supply unit 12. Then, as shown in FIGS. 7 to 8, the introduction portion 14 (FIG. 1) is formed on the outer circumferential surface of the folding guide shaft 48 along the vertical direction. If the tape T is wound clockwise as viewed from above so as to be folded back toward the reference), the tape T is wound on the side opposite to the supply guide portion 21 of the folding guide shaft 48 while keeping the width direction in the vertical direction. It will be in the state turned back to the supply guide part 21 side, ie, the introduction part 14 side. At this time, the tape T comes into contact with the folding guide shaft 48 on the non-glue surface t2.

  From this state, as shown in FIG. 9, when the folding guide shaft 48 of the folding unit 13 is tilted to fall sideways, the tape T is rotated in a predetermined clockwise direction when viewed from the supply guide unit 21 side. The direction of the tape T is changed by twisting about 90 degrees, and the tape T is brought into a posture in which the width direction is in the horizontal direction, that is, in the introduction posture to the introduction portion 14. At this time, the non-glue surface t2 of the tape T in contact with the folding guide shaft 48 has the non-glue surface t2 facing upward and the glue surface t1 facing downward. Accordingly, if the tape T is introduced into the introduction portion 14 as shown in FIG. 1 without any unreasonable state, the tape T is introduced with the adhesive surface t1 facing downward. That is, the folding guide shaft 48 is in a predetermined correct orientation, specifically, when the tape T from the supply unit 12 is wound in the standing state and is folded back to the introduction unit 14 side, The tape T is twisted in a predetermined direction so that the glue surface t1 faces downward.

  As shown in FIG. 5, the bundling portion 61 is continuous with the introduction portion 14 and has a tape introduction path 62 that is bent in a substantially semicircular shape downward as a whole, and a substantially elliptical shape that is continuous with the tape introduction path 62. And a tape guide portion 63 having a loop shape. The bundling portion 61 includes a plurality of feed rollers 64 for transporting the tape T at the position of the tape introduction path 62, a stamping portion 65 for stamping the non-glue surface t2 of the tape T, and a non-glue surface of the tape T. A printer 66 for printing at t2 is provided.

  In addition, the bundling portion 61 is provided with clamping members 68 and 69 for clamping the banknotes S in a state of being stacked one above the other from the top and bottom inside the tape guide portion 63. A tape pressing member 72 that has an insertion hole 71 through which the tape T fed from the tape introduction path 62 passes, and that is close to and away from the lower clamping member 69, and a tape pressing member below the tape guiding portion 63 A cutter 73 that cuts the tape T in the vicinity of the 72 insertion holes 71 and a heater 74 that sandwiches the tape T with a lower sandwiching member 69 and thermally bonds it are provided.

  The plurality of feed rollers 64 are provided with a feed motor (not shown) for driving them and an operation button 77 shown in FIG. The feed mechanism 78 is configured to automatically feed to the standby position.

  At the time of tape setting, when the operation button 77 of the feed mechanism 78 is pressed in a state where the tape T is folded at the folding portion 13 and introduced into the introduction portion 14 as described above, a feed motor (not shown) is turned on. When a plurality of feed rollers 64 rotate and automatically feed the tape T along the tape introduction path 62, and a sensor (not shown) detects that the tip is located at a predetermined standby position, the feed motor Stops and the tape T is stopped. At this time, the tape T is stopped through the insertion hole 71 of the tape pressing member 72 located at the lower limit position separated from the holding member 69 from the tape introduction path 62.

  From this standby state, during the bundling process, a predetermined number of banknotes S stacked in a stacking unit (not shown) are inserted between the clamping members 68 and 69, and the binding unit 61 uses the clamping member 69. By raising, a plurality of banknotes S are held between the holding member 68 and the holding member 69. In parallel with this, the feed mechanism 78 feeds out the tape T while feeding the non-glue surface t2 with the stamping portion 65 and printing with the printer 66, and feeds the tape T along the tape guide portion 63. , It is made to make a round and stop at a position where the tip overlaps the heater 74. From this state, after the tape pressing member 72 rises and clamps the leading end side of the tape T between the lower surface of the clamping member 69, a feed motor (not shown) rotates the feed roller 64 in a direction to return the tape T, An approximate rewinding motor rotates the set unit 20 in the direction of winding the roll-shaped portion Ta. As a result, the tape T located inside the tape guide portion 63 is wound around the outside of the holding members 68 and 69. Then, the heater 74 is raised so that the sandwiching member 69 causes the adhesive portion located below the distal end portion of the tape T to be in close contact with the distal end portion of the tape T, and the cutter 73 is proximal to the adhesive portion of the tape T. Disconnect. Then, the glue surface t1 of the bonded portion of the tape T is bonded to the non-glue surface t2 of the tip portion of the tape T by the heat of the heater 74. Then, by pulling out the holding members 68 and 69 from the tape T, a small bundle of banknotes obtained by binding a plurality of stacked banknotes S with the tape T is obtained.

  In addition, even if the tape T is consumed and the outer diameter of the roll-shaped part Ta becomes small, the supply part 12 is hung from the supply guide part 21 through the return guide shaft 48 because the tape T is hung on the supply guide part 21. The path of the tape T to all the introduction parts 14 is kept constant.

  According to the paper sheet bundling device of the present embodiment described above, when the folding guide shaft 48 is in a standing state along the width direction in the feeding posture of the tape T from the supply unit 12, the supply unit 12 When the tape T is wound around in the feeding posture and is folded back toward the introduction portion 14 in this manner, the folding guide shaft 48 is tilted and falls sideways. Then, the tape T is automatically twisted in a predetermined direction to change the direction, and the tape T is brought into the introduction posture to the introduction portion 14. Therefore, since the front and back of the tape T can be introduced into the introducing portion 14 in a predetermined direction, it is possible to suppress the occurrence of a binding failure due to a setting error of the tape T to the folding guide shaft 48.

  When the setting direction of the regulating member 40 provided between the setting unit 20 and the supply guide unit 21 to the setting unit 20 of the tape T is appropriate, the tape T guided to the supply guide unit 21. If the setting direction of the tape T on the setting unit 20 is not appropriate, the tape T guided by the supply guide unit 21 interferes with the operator, and the operator sets the tape T on the setting unit 20. Whether or not the direction is appropriate can be recognized visually. Therefore, in the middle of the winding operation of the tape T from the setting unit 20 to the supply guide unit 21, it is possible to make the operator notice that the tape T is mounted in the wrong direction, and correct it correctly. Therefore, it is possible to prevent erroneous attachment of the original tape T to the set unit 20, and to suppress the occurrence of binding defects due to this erroneous attachment. That is, even if the tape T can be set in the correct direction on the folding guide shaft 48, if the tape T is mounted in the reverse direction in the original supply unit 12, as shown in FIG. However, the tape T on the downstream side (introducing portion 14) is in the opposite direction, and this can be prevented.

  In the above description, the folding guide shaft 48 has been described as an example in which the folding guide shaft 48 is in a sideways state due to its own weight from a standing position. However, for example, the base table 22 is mounted in an inclined state because of its inclination. When the return guide shaft 48 is in the standing position, the return guide shaft 48 is in a sideways state rather than the path of the tape T from the supply portion 12 to the introduction portion 14 via the return guide shaft 48 when the return guide shaft 48 is in the standing position. The path of the tape T from the supply unit 12 to the introduction unit 14 via the folding guide shaft 48 is shortened. If comprised in this way, even if the return guide axis | shaft 48 in the state which the tape T from the supply part 12 was wound and was turned in by the introduction part 14 side is still in the standing state, the tape T is the feed mechanism 78. The folding guide shaft 48 is automatically tilted by the tension of the tape T in the sideways state in which the tape path is shorter than the standing state due to the tension due to the tension. That is, even if the forgetting to return the folding guide shaft 48 to the sideways state and proceeding with the operation, when the tape T is automatically fed by the feed mechanism 78, the tape T is tensioned and at least pushed back. The tape T is stretched so that the length of the tape path from the guide shaft 48 to the introduction portion 14 is the shortest, and the folded guide shaft 48 is brought into a sideways state. Therefore, it is possible to prevent a problem caused by forgetting to tilt the folding guide shaft 48 from the standing state to the sideways state.

  Alternatively, the folding guide shaft 48 is screwed to the support shaft 47 that supports the folding guide shaft 48 so that the folding guide shaft 48 is tiltable, and the folding guide shaft 48 is tilted more sideways than the standing position by axial movement during rotation by screwing. May be closer to the introduction part 14. If comprised in this way, even if the return guide axis | shaft 48 in the state which the tape T from the supply part 12 was wound and was turned in by the introduction part 14 side is still in the standing state, tension | tensile_strength arises in the tape T. Then, the folding guide shaft 48 is screwed to the support shaft 47 and automatically tilts to the sideways state closer to the introduction portion 14 than to the standing state. Therefore, it is possible to prevent a problem caused by forgetting to tilt the folding guide shaft 48 from the standing state to the sideways state. Note that a higher effect can be obtained by combining the screwed structure of the support shaft 47 and the folding guide shaft 48 with the structure in which the length of the tape path described above is shortened in the sideways state.

  In the above embodiment, the case where one supply guide unit 21 is provided in the supply unit 12 has been described as an example. A plurality of supply guides 21 may be provided.

  Further, the tape T has been described to rotate in the clockwise direction when viewed from above with respect to the folded-back guide shaft 48 in the standing position, but the present invention is not limited thereto, and the tape T may be rotated in the counterclockwise direction. Even in this case, when the folding guide shaft 48 is tilted, the non-glue surface t2 of the tape T is naturally twisted so as to be in the correct setting direction facing the upper part.

  Further, the tape T has been circulated along the folding guide shaft 48. However, the present invention is not limited to this, and a slit through which the tape T is passed may be provided in the folding guide shaft 48. Even when the tape T is passed through the slit of the folding guide shaft 48 in the standing position and the folding guide shaft 48 is tilted, the tape T is naturally twisted so that the non-glue surface t2 of the tape T is in the correct setting direction facing the top. It will be.
