Description

  The present invention relates to a piece winding device for winding a piece around a hole formed in a sheet.

  There is a binding device that binds with a tape instead of a metal needle when binding a document (see Patent Documents 1 and 2). For example, in the binding device of Patent Document 1, after making a hole in a bundle of documents, the document is moved from the punching position to the binding position, and in conjunction with this movement, an adhesive tape is attached to the hole of the document by the insertion member. Is inserted, and the bundle of documents is returned to the original position from the binding position so that the adhesive tape is wound around. However, the binding device of Patent Document 1 needs to be manually moved to a binding position after making a hole in a bundle of documents at the punching position, and the operation is troublesome. In addition, when the stack of documents is moved from the punching position to the binding position, if the position of the stack of sheets is shifted, the stack of documents is damaged by the insertion member.

  Further, in the binding device of Patent Document 2, when inserting a sheet, the end of the sheet is pressed against the binding tape that is waiting to be peeled off, and the adhesive tape is attached to the end of the sheet, and then the punching blade is passed through the sheet. The end of the binding tape attached to the end of the paper is penetrated through the paper as the extraction blade is pulled out, and the paper is bound with the binding tape.

  However, when the paper is thin, for example, the binding device of Patent Document 2 is bent when the paper is inserted and the edge of the paper is pressed against the tape that is waiting to be peeled off, and the tape is attached to the edge of the paper. There is a risk that. Also, since the binding tape is peeled off and the adhesive layer is exposed, the adhesive tape is exposed, so that when the tape is standby for a long time, the adhesive force of the binding tape is reduced, and the paper can be bound with the tape reliably. There is also a risk that it will not be possible. Also, when passing the tape through the paper with the punching blade, there is no gap between the hole and the punching blade in the paper, so the binding tape is actively pressed against the paper and the adhesive surface tries to stick to the paper . Since the binding tape is passed through the paper against this sticking force, the load for inserting the binding tape is large, and the adhesive surface is rubbed, so that the adhesive force is also reduced.

As shown in FIG. 1 and FIG. 2, the single winding device 10 to which the present invention is applied has a hole 2 formed in a sheet bundle 1 in which a plurality of sheets are stacked, and a piece 3 is wound around the hole 2, thereby An apparatus for binding the bundle 1. As shown in FIGS. 3A to 3D, the sheet bundle 1 is formed by laminating paper sheets such as documents, sheet-like members formed of a metal material, a resin material, or the like. In the vicinity of the end of the sheet bundle 1 on the insertion end side, a hole 2 penetrating in the thickness direction is formed. The hole 2 is a punch hole formed in the sheet bundle 1 by the punching blade 67 after the sheet bundle 1 is inserted into the single winding device 10. The sheet bundle 1 includes one surface 1a, an end surface 1c on the insertion end side, the other surface 1b, the hole end surface 2a of the hole 2, and one piece 1 over one surface 1a (here 5 or more). Surface) is wound. At this time, the sheet bundle 1 is wound with the pieces 3 in a state where a plurality of sheets are stacked (for example, a sheet bundle having a small number of sheets to a thick sheet bundle having a large number of sheets). Of course, the piece 3 may be wound with only one sheet.

  As shown in FIGS. 4A and 4B, the piece 3 is formed, for example, in a substantially rectangular shape in plan view, and has an adhesive layer 4 on the other surface 3b. A plurality of temporary papers are temporarily attached to the release paper 5 at predetermined intervals in the longitudinal direction. Thereby, even if it is a case where the piece 3 is used after having waited for a long period of time, the fall of the adhesive force of the adhesion layer 4 can be prevented. Furthermore, the belt-like body 6 composed of the piece 3 and the release paper 5 is wound into a roll shape to form a roll body 8 (see FIG. 1), for example, and a roll provided in the base unit 11 of the piece winding device 10. The container 13 is rotatably accommodated. A plurality of engagement holes 7 are formed in the release paper 5 of the belt-like body 6 at predetermined intervals in the longitudinal direction to engage with an engagement member 36 for feeding the belt-like body 6. The engagement hole 7 may be a hole that penetrates the piece 3 and the release paper 5.

  Note that the length of the piece 3 is determined by how much the sheet 3 is wound around the hole 2 of the sheet bundle 1. Here, the one surface 1 a, the end surface 1 c on the insertion end side, the other surface 1 b, The piece 3 is formed in such a length that it can be wound around one or more rounds (here, 5 surfaces) over the hole end surface 2a and the one surface 1a. Therefore, when one surface 1a, the end surface 1c on the insertion end side, the other surface 1b, and the hole end surface 2a of the hole 2 are wound on four surfaces, the length is shortened accordingly, and the one surface 1a, the insertion end When winding the three surfaces of the side end surface 1c and the other surface 1b, the length is further shortened accordingly. Further, the piece 3 may be wound around the hole 2 by six or more surfaces. When the piece 3 is wound more in the hole 2, the sheet bundle 1 can be bound more firmly.

  As shown in FIGS. 1 and 2, the single-winding device 10 includes a base unit 11 serving as a base portion on which the sheet bundle 1 to be bound is placed, and an operation unit provided to be rotatable with respect to the base unit 11. And a handle 12. Further, the base unit 11 has a roll accommodating portion 13 that rotatably accommodates a roll body 8 formed by winding a strip 6 of the pieces 3 binding the sheet bundle 1 in a roll shape on the rotation fulcrum side of the handle 12. Is provided. At a position straddling the base unit 11 and the handle 12, a one-feed mechanism 14 that extracts the piece 3 from the belt-like body 6 led out from the roll housing portion 13 is provided. Further, the base unit 11 is provided with a winding mechanism 15 for winding the piece 3 around the hole 2 of the sheet bundle 1 in the vicinity of the rotation fulcrum of the handle 12. Further, a punching unit 16 for punching holes 2 in the sheet bundle 1 is provided on the base unit 11.

  In the single winding device 10, when the sheet bundle 1 is inserted between the base unit 11 and the punching unit 16 and the handle 12 is rotated, one piece 3 is wound from the single feeding mechanism 14 to the winding mechanism 15. To be discharged. At the same time, the hole 2 is punched in the sheet bundle 1 by the punching unit 16, and then the piece 3 is placed in the hole 2 by the winding mechanism 15 on one surface 1 a, as shown in FIG. It is wound over the end surface 1c on the insertion end side, the other surface 1b, and the hole end surface 2a of the hole 2. Thereafter, when the handle 12 returns to the original position and the sheet bundle 1 is pulled out, the sheet bundle 1 is pasted so that the piece 3 finally overlaps the piece 3 stuck on the one surface 1a. By doing so, it becomes a bound state. Hereinafter, each mechanism which comprises the piece winding apparatus 10 is demonstrated with reference to drawings.

<2. Explanation of base unit configuration>
As shown in FIGS. 1 and 2, the base unit 11 is formed in a rectangular box shape, for example, and is provided with a roll accommodating portion 13 on one end side in the longitudinal direction, and the base unit 11 is opposed to each other. The handle 12 is rotatably supported by a support shaft 22 provided on the piece. The base unit 11 incorporates a winding mechanism 15 of the piece 3 on the pivot fulcrum side of the handle 12, and the upper surface 23 of the base unit 11 is perforated so as to face the winding mechanism 15. A unit 16 is provided. The punching unit 16 is slidably mounted on the upper surface 23. Although details are omitted, the punching unit 16 slides on the upper surface 23 between a punching position facing the winding mechanism 15 and a maintenance position on the other end side of the base unit 11 (insertion side of the sheet bundle 1). When in the maintenance position, the winding mechanism 15 is exposed to the outside so that maintenance work can be easily performed (see FIGS. 16A and 16B).

  As shown in FIGS. 1 and 5, the base unit 11 has a dust case for storing substantially circular dust generated when the holes 2 are punched in the sheet bundle 1 by the punching blade 67 of the punching unit 16 on the bottom surface side thereof. 24 is arranged. If the dust accumulated in the dust case 24 is not diffused, the dust accumulates in one place, and the capacity of the dust case 24 may not be fully utilized. If the dust overflows from inside the dust case, the dust may stick to the piece 3 and a spelling failure may occur. Therefore, the dust case 24 can be stored in a case storage portion 24 a provided on the bottom surface side of the base unit 11, and is slid from the other end side (insertion side of the sheet bundle 1) of the base unit 11. Attached to the bottom. The dust case 24 is opened at least at a position facing the punching blade 67 of the punching unit 16 and is configured to receive dust.

  On the bottom surface 25b of the dust drop point, a protruding portion 25 is formed at a corner portion with the insertion surface 25c to the case storage portion 24a. The protruding portion 25 is formed so that the side of the punching blade 67 of the punching unit 16 is high, and is lowered as the distance from the punching blade 67 increases. Moreover, the top surface of the protrusion part 25 is the inclined surface 25a comprised by the plane, for example. The dust punched out by the punching blade 67 first hits a high portion of the projecting portion 25, and then divides into the left and right sides of the projecting portion 25 and falls to the bottom surface 25b, and slides down to the bottom surface 25b along the inclined surface 25a. . As a result, the dust is dispersed and dropped in the dust case 24, and it is possible to prevent the punching blade from malfunctioning by being accumulated under the punching blade 67 of the punching unit 16. it can. The dust case 24 is accommodated by being slid in and out of the case accommodating portion 24a with the side surface on the protruding portion 25 side from the other end side (sheet bundle 1 insertion side) of the base unit 11 as an insertion end. Of course, the protrusion part 25 of the dust case 24 may be comprised by the rectangular piece in which the inclined surface 25a is not provided, and the top surface may be not a plane but a cross-sectional view mountain shape.

<3. Explanation of the structure of the handle>
As shown in FIG. 1, the handle 12 provided rotatably on the base unit 11 is rotatably supported by a support shaft 22 provided on a rising piece facing the base unit 11. The handle 12 is urged to rotate in a direction away from the upper surface 23 of the base unit 11 by an urging member such as a torsion coil spring or a coil spring. The urging member has one end locked to the handle 12 and the other end locked to the rising piece of the base unit 11 so that the handle 12 is separated from the upper surface 23 of the base unit 11 in FIG. Turn biased in the A direction.

<4. Explanation of configuration of single feed mechanism>
As shown in FIG. 1, the base unit 11 is provided with a roll accommodating portion 13 on one end side in the longitudinal direction, and the roll accommodating portion 13 supports the piece 3 from a roll body 8 that is rotatably accommodated. The belt-like body 6 is fed by the one-feed mechanism 14 in conjunction with the rotation of the handle 12. Then, one piece 3 is discharged onto the winding mechanism 15. At this time, if the feed amount of the piece 3 is not constant, the winding position of the piece 3 changes, and there is a possibility that the piece 3 cannot be wound stably. Specifically, as shown in FIGS. 1 and 6A, the single feed mechanism 14 includes a folding guide member 32 that folds the belt-like body 6 at the position of the discharge portion 31 that discharges the piece 3 in the base unit 11. Have. The folding guide member 32 is provided to face the support guide member 33 that extends from the roll body 8 provided on the base unit 11 side and supports the belt-like body 6 from below. The folding guide member 32 has a C-shaped folding portion 32a in the vicinity of the discharge portion 31 of the piece 3, and the first half guide portion 32b facing the support guide member 33 and the piece 3 are peeled off on both sides of the folding portion 32a. And a second half guide portion 32c for guiding the belt-like body 6.

  The belt-like body 6 from which the piece 3 is not peeled is sent out to the discharge portion 31 through the space between the support guide member 33 and the first half guide portion 32b, and the travel path is folded back by the folding portion 32a. At this time, the strip 6 is bent along the folded portion 32 a, whereby the piece 3 is peeled from the release paper 5, and only the piece 3 is discharged to the discharge portion 31. The belt-like body 6 made of the release paper 5 from which the piece 3 is peeled is guided by the latter half guide portion 32c and discharged to the outside. The piece 3 is discharged from the discharge unit 31 so that the adhesive layer 4 faces upward, that is, the adhesive layer 4 faces the front half guide portion 32b so as to face the one surface 1a of the sheet bundle 1. become.

  As shown in FIGS. 6 (A) to 6 (C), the discharge section 31 for discharging the piece 3 peeled from the release paper 5 allows the lower guide member 34 and the upper guide member 35 to pass almost the piece 3. Opposite positions are spaced apart by a distance. As shown in FIGS. 6A and 6B, the lower guide member 34 supports the surface of the piece 3 peeled from the release paper 5 opposite to the adhesive layer 4. Since the upper guide member 35 is a member corresponding to the adhesive layer 4 of the piece 3, as shown in FIG. 6C, the upper guide member 35 is formed in a C-shaped cross section so as to avoid contact with the adhesive layer 4. Further, each end of the upper guide member 35 is cut into a mountain, and the inner inclined surfaces 35a, 35a are in contact with and guide both side edges of the piece 3 in the longitudinal direction. The roll body 8 is wound around the belt-like body 6 so that the piece 3 is on the inside. Therefore, when the belt-like body 6 is pulled out from the roll body 8, a state in which a curl is attached in the direction of the lower guide member 34. The adhesive layer 4 is difficult to attach to the upper guide member 35 even when the piece 3 is peeled off from the release paper 5. The upper guide member 35 can reliably insert the piece below the sheet bundle while suppressing the movement of the peeling piece 3 up and down.

  As shown in FIGS. 6 and 7, the one-side feed mechanism 14 further includes an engagement member 36 that sends the belt-like body 6 and a feed member 37 that moves the engagement member 36. The engaging member 36 is movably provided on a movement guide member 36 a provided in the roll accommodating portion 13 or the base unit 11, and is connected by the connecting pin 36 b being engaged with the connecting groove 37 d of the feeding member 37. Is done. The engaging member 36 is formed with an engaging protrusion 36 c that engages with the engaging hole 7 of the belt-like body 6. The engagement protrusion 36c is a hook-shaped protrusion that opens in the direction of arrow B, which is the feeding direction of the belt-like body 6, and has a shape that can be easily engaged with the engagement hole 7 (see FIG. 4) of the belt-like body 6. Further, the shape of the piece 3 is difficult to come off. The engaging member 36 is elastically biased in the direction of the belt-like body 6 by an elastic body 36d such as a coil spring so that the engaging protrusion 36c can be easily engaged with the engaging hole 7 of the belt-like body 6. .

  The engaging member 36 as described above is moved in the arrow B direction by the feed member 37 in conjunction with the rotation of the handle 12. The feed member 37 includes a first member 37a and a second member 37b that are rotatably connected. Specifically, the first member 37 a and the second member 37 b are pivotally supported so that their respective shaft holes are inserted into a support shaft 37 c spanning the rising piece of the base unit 11 and are rotatable. . As shown in FIGS. 1 and 7, the first member 37 a is a pressed member whose tip is pressed against the inner surface of the handle 12 when the handle 12 is rotated. The second member 37 b that can rotate with respect to the first member is an operation member that operates the engagement member 36. The second member 37b is connected when the connecting pin 36b of the engaging member 36 engages with the long connecting hole 37d. The first member 37a and the second 37b are urged in the direction of the arrow C by the urging member 38 such as a torsion coil spring at the position of the support shaft 37c so that they are in a linear positional relationship in the standby state. Yes.

As shown in FIG. 1, when the handle 12 is in a standby state separated from the base unit 11, the tip of the first member 37 a of the feed member 37 is not pressed against the inner surface of the handle 12. When the handle 12 is rotated in the counter direction of arrow A, the inner surface of the handle 12 is in contact with the distal end portion of the first member 37a, when the handle 12 is further rotated against the urging member 38 The first member 37a rotates around the support shaft 37c with respect to the second member 37b. Then, as shown in FIG. 6B, the engaging member 36 connected via the second member 37b moves in the direction of arrow B, thereby feeding and feeding one piece 3. . As shown in FIG. 7, the feeding operation of the engaging member 36 stops when the second member 37b hits the support shaft 22 serving as a stopper. By engaging the engaging member 36 against the support shaft 22 while being urged by the urging member 38, the feeding amount of one piece 3 can be made constant without being affected by the dimensional accuracy of other parts. A jam or the like due to a defect or the like can be prevented. The handle 12 is further rotated in the direction of the arrow A to move to a punching operation for forming the hole 2 in the sheet bundle 1. At this time, the first member 37 a hits the support shaft 22 that serves as a stopper. Thus, thereafter, the second member 37b further rotates around the support shaft 37c with respect to the first member 37a against the urging force of the urging member 38. Thereby, when the handle | steering-wheel 12 rotates further, the piece winding apparatus 10 can transfer to punching operation | movement.

<5. Explanation of configuration of winding mechanism>
<5-1. Explanation of wound nails>
As shown in FIGS. 1 and 8, the winding mechanism 15 that winds the piece 3 discharged from the discharge unit 31 around the hole 2 of the sheet bundle 1 includes a winding tool 40. The winding tool 40 is provided with a winding claw 41 for winding the piece 3 discharged from the discharge portion 31 around the hole 2 of the sheet bundle 1. As shown in FIGS. 8A to 8C, the wound claw 41 is formed, for example, by being bent or bent in a C shape, and is provided so as to be rotatable around a rotation shaft 42. Specifically, the winding claw 41 is rotated as shown in FIG. 8C from a standby state in which the front end portion 41a is located on the upper surface 23 side of the base unit 11, and the sheet bundle 1 While pressing the free end of the piece 3 adhered to one surface 1a of the sheet (the portion not adhered to one surface 1a of the sheet bundle 1), the other end surface 1c of the sheet bundle 1 and the other of the sheet bundle 1 are pressed. The surface 1b and the hole end surface 2a of the hole 2 are wound in this order. When the winding of the piece 3 is completed, the winding tool 40 reverses and returns to the standby state.

  9A and 9B, the winding claw 41 has an end surface 1c of the sheet bundle 1 and the other surface 1b of the sheet bundle 1 while the front end portion 41a presses the free end of the piece 3. When winding in the order of the hole end surface 2a of the hole 2, the inner peripheral pressing surface 41b in the middle of the inner peripheral surface of the winding claw 41 presses the position of the hole end surface 2a. The pressure-sensitive adhesive layer 4 is pressed against the hole end surface 2a. In this way, the inner peripheral pressing surface 41b of the winding claw 41 interferes with the hole end surface 2a of the hole 2 of the sheet bundle 1 so that the pieces 2 can be reliably attached regardless of the thickness of the sheet bundle 1. it can. For example, FIG. 9A shows the case of a small number of sheet bundles, and FIG. 9B shows the case of a large number of thick sheet bundles 1. In any case, the inner peripheral pressing surface 41b of the wound claw 41 can reliably press and adhere the adhesive layer 4 of the piece 3 at the position of the hole end surface 2a of the hole 2 of the sheet bundle 1.

<5-2. Explanation of rotation mechanism>
Next, a rotation mechanism 51 that constitutes a part of the winding mechanism 15 that rotates the winding tool 40 having the winding claw 41 configured as described above will be described with reference to FIGS. As shown in FIGS. 10 to 14, the rotation mechanism 51 includes an arcuate gear 52 provided on the proximal end side of the handle 12, a drive gear member 53 rotated by the arcuate gear 52 of the handle 12, and a drive A rack link member 54 slid by the gear member 53 and a rack member 55 that slides integrally with the rack link member 54 and rotates the winding tool 40 are provided.

  The drive gear member 53 is rotatably supported by the rising piece of the base unit 11 and has a gear portion 53 a that meshes with the arcuate gear 52 of the handle 12. The drive gear member 53 is formed with drive pins 53b for sliding the rack link member 54 and the rack member 55. The rack link member 54 is a long rectangular member, and is slidably attached to the rising piece of the base unit 11. The rack link member 54 is formed with a first engagement piece 54a with which the drive pin 53b of the drive gear member 53 is engaged. The rack member 55 is attached to the rising piece of the base unit 11 so as to overlap the rack link member 54 and slides integrally with the rack link member 54. The rack member 55 is formed with a second engagement piece 55a with which the drive pin 53b of the drive gear member 53 is engaged. The rack link member 54 and the rack member 55 are connected by an elastic body 56 such as a coil spring, and the rack link member 54 slides against the rack member 55 against the elastic force of the elastic body 56. To do. Further, the rack link member 54 is formed with guide pins 54 b that guide the slide with the rack member 55, and the guide pins 54 b are engaged with the guide holes 55 b of the rack member 55.

  The rack member 55 is formed with first to third engaging recesses 55c, 55d, and 55e side by side. The engagement pins of the winding tool 40 are sequentially engaged with the first to third engagement recesses 55c, 55d, and 55e. Thereby, the winding tool 40 rotates in accordance with the slide of the rack member 55. In the winding tool 40, a circular rotation drive unit 43 is formed on a rotation shaft 42. A plurality of engaging portions 44, 44, 44 that engage with the first to third engaging recesses 55 c, 55 d, 55 e are formed in the rotation drive portion 43. As the rack member 55 slides, any one of the engaging portions 44, 44, 44 is engaged with the first to third engaging recesses 55c, 55d, 55e in order. Thereby, the winding tool 40 rotates according to the slide of the rack member 55, when the engaging parts 44, 44, and 44 push the standing wall of the 1st-3rd engaging recessed parts 55c, 55d, and 55e. become.

  Next, the operation | movement which rotates the winding tool 40 is demonstrated. As shown in FIG. 12A, when the handle 12 is in the standby position, the winding pawl 41 is in a state of being retracted to the lower side of the upper surface 23 of the base unit 11. When the turning operation of the handle 12 is started, as shown in FIG. 12 (B), the arcuate gear 52 of the handle 12 moves in the direction D1, so that the drive gear member 53 engaged with the arcuate gear 52 is , Rotate in the E1 direction. At this time, the drive pin 53b of the drive gear member 53 moves in the E1 direction away from the first engagement piece 54a. That is, the drive gear member 53 idles for a while after starting to rotate. As shown in FIG. 12B, when the drive pin 53b of the drive gear member 53 comes into contact with the first engagement piece 54a of the rack link member 54, the drive pin 53b rotates the E1 direction of the drive gear member 53. Then, the first engagement piece 54a is pressed. Thereby, the rack link member 54 compresses the elastic body 56 and slides relative to the rack member 55 in the direction of arrow F1. As shown in FIG. 13A, the drive gear member 53 continues to rotate in the E1 direction until the handle 12 descends to the bottom dead center, and the drive pin 53b continues to push the first engagement piece 54a. When separated from the engagement piece 54a, the rack link member 54 slides in the direction of arrow F2 according to the elastic restoring force of the elastic body 56 and returns to the original position. In the state shown in FIGS. 12B to 13A, a punching blade 67 described later is moved down to make a hole 2 in the sheet bundle 1.

  As shown in FIG. 13B, when the handle 12 is lifted from the bottom dead center, the arcuate gear 52 of the handle 12 moves in the direction D2, so that the drive gear member 53 meshed with the arcuate gear 52 is obtained. Rotates in the E2 direction. Then, the drive pin 53b of the drive gear member 53 presses the first engagement piece 54a and slides the rack member 55 integral with the rack link member 54 in the direction of arrow F2. As the rack member 55 slides in the direction of arrow F2, the first engagement portion 44 engaged with the first engagement recess 55c of the rack member 55 is first pushed, and the winding tool 40 rotates in the G1 direction. . Next, when the second engagement portion 44 is engaged with the second engagement recess 55d and the second engagement portion 44 is pushed, the winding tool 40 further rotates in the G1 direction. Furthermore, the third engaging portion 44 engages with the third engaging recess 55e and the third engaging portion 44 is pushed, whereby the winding tool 40 further rotates in the G1 direction. Thus, the winding claw 41 of the winding tool 40 rotates when the handle 12 is raised, presses the free end of the piece 3 with the tip end portion 41 a, and the piece 3 becomes the other end of the sheet bundle 1 and the other end of the sheet bundle 1. Can be wound in the order of the surface 1b and the hole end surface 2a of the hole 2.

  Further, when the handle 12 is raised, as shown in FIGS. 13B and 14, the drive gear member 53 meshed with the arcuate gear 52 further rotates in the E2 direction. Then, the drive pin 53b of the drive gear member 53 moves away from the first engagement piece 54a and presses the second engagement piece 55a of the rack member 55 after idling. Then, the rack member 55 slides in the arrow F1 direction. Then, the engaging portions 44, 44, 44 of the winding tool 40 are engaged with the second engaging concave portion 55d and the first engaging concave portion 55c in order from the third engaging concave portion 55e. Thereby, the winding tool 40 rotates in the arrow G2 direction and returns to the standby position below the upper surface 23 from the position where the piece 3 is wound.

  The piece 3 is wound around the hole 2 punched by the punching blade 67 with the winding claw 41 after the hole 2 is punched in the sheet bundle 1 by the punching blade 67. Therefore, in the rotation mechanism 51, the movable area of the winding claw 41 overlaps with the movable area of the punching blade 67, and if they operate simultaneously, they collide with each other. Therefore, the rotating mechanism 51 is configured to pierce the hole 2 in the sheet bundle 1 with the punching blade 67 when the handle 12 moves forward, and rotates the winding claw 41 when performing the return return operation, and pierces with the forward operation. The pieces 3 are inserted and wound around the formed holes 2 to prevent interference with each other. According to this configuration, even if the handle 12 is moved up and down during the operation, the punching blade 67 and the winding claw 41 do not interfere with each other.

  By the way, if the handle 12 is forcibly rotated when the foreign matter 45 exists in the movable region of the winding pawl 41, the winding tool 40, the rack link member 54, the rack member 55, and the like may be damaged. Therefore, in the example of FIGS. 15A and 15B, the buffer lever 57 and the elastic member 58 are provided. That is, the buffer lever 57 is an integral member with the rack link member 54 and is rotatably provided on a support shaft 57 a provided on the rack link member 54. The buffer lever 57 is provided with a first engagement piece 54a formed on the rack link member 54 in the previous example. An elastic member 58 such as a torsion coil spring is bridged between the rack link member 54 and the buffer lever 57. The elastic member 58 urges the buffer lever 57 to rotate in the direction indicated by the arrow H in FIG.

  As shown in FIG. 15A, when there is a foreign object 45 in the movable area of the winding claw 41, when the tip 41a of the winding claw 41 contacts the foreign object 45, the winding claw 41 further rotates in the G1 direction. Can not do. On the other hand, the handle 12 is raised, the arcuate gear 52 moves in the direction D2, the drive gear member 53 rotates in the direction of the arrow E2, and the drive pin 53b presses the first engagement piece 54a of the buffer lever 57. Then, the rack link member 54 is slid in the arrow F2 direction. Then, the buffer lever 57 rotates in the direction of the arrow H about the support shaft 57a against the urging force of the elastic member 58, and the drive pin 53b moves to the first engagement as shown in FIG. The joint piece 54a can be overcome. As a result, the drive pin 53b does not force the first engagement piece 54a and can prevent the drive pin 53b from being bent or the winding claw 41 from being broken. Thereafter, as shown in FIG. 14, the drive pin 53b of the drive gear member 53 moves away from the first engagement piece 54a, and after idling, presses the second engagement piece 55a of the rack member 55, The rack member 55 slides in the direction of the arrow F1, and the winding tool 40 rotates in the direction of the arrow G2 to return from the position where the piece 3 is wound to the standby position below the upper surface 23.

<6. Explanation of configuration of drilling unit>
<6-1. Explanation of drilling unit drill>
The punching unit 16 that punches holes 2 in the sheet bundle 1 is attached to the upper surface 23 of the base unit 11 so as to be slidable in the longitudinal direction, as shown in FIGS. This is because, when the punching unit 16 is fixed, it is difficult to remove the attached piece when the piece 3 is attached in the winding device. That is, the punching unit 16 slides across the punching position facing the winding mechanism 15 of the base unit 11 and the maintenance position on the other end side (the insertion side of the sheet bundle 1) of the base unit 11 and is in the maintenance position. At this time, the discharge unit 31 and the winding mechanism 15 are exposed to the outside so that maintenance work can be easily performed. That is, since the winding mechanism 15 is exposed to the outside when the punching unit 16 is in the standby position, the adhesive attached to the winding claw 41 of the winding mechanism 15, the piece 3 attached to the winding claw 41, The operation of removing the punching blade 67 of the perforating unit 16 and the pieces 3 attached to the periphery thereof can be easily performed. Further, the winding tool 40 can be easily replaced.

  As shown in FIG. 17, the punching unit 16 has a slide base 61, and the slide base 61 slides on the upper surface 23 of the base unit 11 in the longitudinal direction. The slide base 61 is formed with guide pieces 62b and 62b that engage with guide rails 62a and 62a formed on both sides of the upper surface 23 of the base unit 11, and the guide pieces 62b and 62b are located outside the guide rails 62a and 62a. Engage with the surface. Furthermore, engagement guide pieces 63b and 63b are formed inside the guide pieces 62b and 62b. The engagement guide pieces 63b and 63b are formed on the upper surface of the base unit 11 along the longitudinal direction. 63a is engaged. Thus, the punching unit 16 can move along the longitudinal direction of the base unit 11 on the upper surface 23 of the base unit 11.

  Further, as shown in FIGS. 19 and 20, the slide base 61 is provided with lock members 64 for locking the drilling unit 16 at the drilling position on both sides. Although not shown, the locking member 64 engages with the engaging portions formed on the guide rails 62a and 62a on the upper surface 23 of the base unit 11, thereby locking the drilling unit 16 in the drilling position. The lock member 64 is always urged in the locking direction to engage with the engaging portions on the guide rails 62a and 62a side, and is operated by the user to release the locked state with the engaging portion, and the standby position. It becomes possible to slide in the direction. Of course, the lock member 64 may be provided only on one side.

<6-2. Explanation of the sheet bundle abutment section>
By the way, this punching unit 16 is provided with a punching blade on the upper side of the slide base 61, and further, a die 67b that receives the punching blade 67 is integrally provided on the upper surface of the slide base 61. Are provided in the unit that slides, so that the positional accuracy between the punching blade and the die 67b is increased as compared with the case where the die 67b is provided on the base unit 11 side. Specifically, the upper surface of the slide base 61 is a placement surface 65 on which the sheet bundle 1 is placed, and the back of the placement surface 65 is formed with rising pieces as shown in FIG. The abutting portions 66 and 66 against which the leading end portion of the sheet bundle 1 is abutted. This is because if the piece 3 is attached to the end surface of the sheet bundle 1 at an angle, the tape cannot be inserted into the hole of the sheet bundle 1 in a later process. Therefore, the abutting portions 66 and 66 are exposed to the outside, and it is possible to confirm whether or not the sheet bundle 1 inserted by the user has abutted against the abutting portions 66 and 66.

<6-3. Explanation of the cutting blade>
As shown in FIG. 1 and FIGS. 8A to 8C, the cutting blade 67 is attached to the slide base 61 as described above so as to be slidable in a direction perpendicular to the mounting surface 65. The punching blade 67 is elastically biased in the direction of the arrow I that is separated from the die 67b by an elastic body 68 such as a coil spring. The punching blade 67 is pressed according to the turning operation of the handle 12 and is pressed and slid in the direction of arrow I for punching the sheet bundle 1. One end of the punching blade 67 is a blade portion for punching the sheet bundle 1 and enters the through hole 67c of the die 67b. The other end 67 a is a pressed portion that is pressed by the handle 12. The other end 67a is formed to protrude outward. As shown in FIGS. 1, 2, and 7, the handle 12 that presses the punching blade 67 is provided with a punching blade pressing portion 70 that presses the other end 67 a of the punching blade 67 on the inner surface thereof. The punching blade pressing unit 70 presses the punching blade 67 in the direction of arrow I during drilling (when the handle 12 is in the forward path). When the handle 12 returns, the other end 67a of the punching blade 67 is engaged with the engagement piece 70a formed on the punching blade pressing portion 70 in the first half of the return path operation, and is engaged with the engagement piece 70a in the second half. The state is released. Thereafter, the punching blade 67 returns to the initial position by the elastic restoring force of the elastic body 68.

  As shown in FIGS. 8A to 8C, the slide base 61 is formed with a guide hole 69 through which the punch blade 67 moves at a position facing the die 67b across the space in which the sheet bundle 1 is inserted. Has been. When the sheet bundle 1 is perforated so as to face the space portion where the sheet bundle 1 is placed at the front end portion of the guide hole 69, the sheet bundle 1 that is lifted by the lifting blade 67 that rises is provided. A lifting restricting portion 69a to be pressed is formed.

<6-4. Explanation of holding member and lifting member>
As shown in FIGS. 19 and 20, the slide base 61 is provided with a sheet pressing member 71 around the punching blade 67 to press the sheet bundle 1 inserted and abutted against the abutting portions 66 and 66 and positioned. It has been. Although not shown, the sheet pressing member 71 is guided to slide in the same direction as the punching blade 67 by guide means integrated with the slide base 61. The sheet pressing member 71 has a through hole 72 through which the punching blade 67 is inserted, and movement amount regulating grooves 73 for restricting the moving amount of the punching blade 67 are formed on both sides of the through hole 72. The movement amount regulation groove 73 is engaged with a regulation projection 74 formed on the punching blade 67. When the punching blade 67 is pushed by the handle 12, the movement amount regulating groove 73 presses the sheet pressing member 71 in the direction of arrow I with the regulating projection 74 hitting the lower end 73 a. Thus, in conjunction with the punching operation of the punching blade 67, the sheet pressing member 71 also slides in the same direction as the punching blade 67 sliding in the punching direction.

  As shown in FIGS. 21 and 23, the sheet pressing member 71 has a pair of sheet pressing portions 75 and 75 on both sides of the punching blade 67. The sheet pressing portions 75, 75 press both sides of the punching blade 67 when punching the sheet bundle 1 with the punching blade 67, and prevent the sheet bundle 1 from being displaced during punching. Further, when the piece 3 is wound around the hole 2, the sheet 3 is slightly positioned away from the sheet bundle 1 in which the hole 2 is formed, and the upper surface of the sheet bundle can be set at a fixed position regardless of the number of sheets.

  Sheet push-up members 76 and 76 that push up the sheet bundle 1 on the placement surface 65 of the slide base 61 are provided at positions facing the sheet press portions 75 and 75. The sheet push-up members 76, 76 are, for example, leaf springs provided on the placement surface 65, and lift the insertion end of the sheet bundle 1 away from the placement surface 65 when the sheet bundle 1 is inserted. A gap 80 is formed between the placement surface 65 and the lower surface of the sheet bundle 1, and the gap 80 is fed from the one-feed mechanism 14 between the pair of sheet push-up members 76, 76 to the discharge unit 31. The piece 3 discharged from enters. The piece 3 is inserted below the one surface 1a with the adhesive layer 4 facing the one surface 1a of the sheet bundle 1, but the sheet bundle 1 is pushed up by the sheet push-up member 76 and has a sufficient gap. Since 80 is formed, it is possible to prevent sticking to one surface 1a of the sheet bundle 1 while the piece 3 is being discharged, and stable to one surface 1a of the sheet bundle 1. Then, the piece 3 can be pasted.

  As shown in FIGS. 22 and 23, when the handle 12 is operated, the punching blade 67 is pushed in the direction of arrow I, and the sheet pressing member 71 slides in the same direction in conjunction with the sliding of the punching blade 67. . As a result, the sheet pressing portions 75 and 75 of the sheet pressing member 71 sandwich the sheet bundle 1 with the sheet lifting member 76 on both sides of the punching blade 67. At this time, both sides of the extraction blade 67 of the sheet bundle 1 supported by the die 67 b are pressed against the sheet pressing portions 75, 75, and sink against the pressing force of the sheet pressing member 76. Thereby, the adhesive layer 4 of the piece 3 located on both sides of the sheet pressing portions 75 and 75 is firmly attached to one surface 1 a of the sheet bundle 1.

  By the way, the larger the distance between the position where the sheet bundle 1 is pressed and sunk by the sheet pressing portions 75, 75 and the position of the die 67b, the more the adhesive layer 4 of the piece 3 is pressed against the one surface 1a of the sheet bundle 1. The power to apply increases. Therefore, as shown in FIG. 24, in the vicinity of the die 67b of the placement surface 65, when the sheet bundle 1 is pressed by the sheet pressing portions 75, 75, the position of the sheet bundle 1 is increased at the position of the die 67b. The convex portions 77 and 77 may be formed. Further, as shown in FIG. 25, a protrusion 78 having a predetermined width may be formed.

  FIG. 26A shows a state where a small number of sheet bundles are inserted. In the sheet pressing portions 75 and 75, the lowest point is set below the sheet bundle 1, and as shown in FIG. 27A, when a large number of thick sheet bundles 1 as the maximum number are inserted, Maximum load is applied at the lowest point. Then, as shown in FIG. 26 (B), the sheet pressing portions 75 and 75 once descend to the lowest point, and then retract to a position where no load is applied to the sheet bundle 1 following the return path operation of the handle 12. To do. As shown in FIG. 27B, in the case of a large number of thick sheet bundles 1, the sheet bundle 1 just contacts the pressing surfaces of the sheet pressing portions 75 and 75.

  In addition, although the sheet | seat holding | suppressing parts 75 and 75 demonstrated above demonstrated the example provided in both sides on both sides of the punching blade 67 as shown to FIG. 28 (A), as shown to FIG. A part of the area indicated by the C-shaped portion around the blade may be constituted by the sheet pressing portion 75. In this case, the sheet pressing portion 75 has substantially the same shape as the facing sheet lifting member 76, and can surround the three directions of the punching blade 67, so that the sheet bundle 1 can be more reliably compared to the case where the pressing is performed at two places. Can be sunk to the bottom of the die 67b.

  In addition, the sheet push-up member 76 described in the above example has been described as being formed by a leaf spring. However, as shown in FIG. 29A, the sheet push-up sheet 76 is formed by resin molding having an inclined push face 76a. The member 76 may be elastically biased in the push-up direction by the coil spring 76b. Further, the sheet push-up member 76 is formed by bending a flat plate into a square shape, and is attached to the placement surface 65 so as to be rotatable. The sheet push-up member 76 may be configured such that one piece that pushes up the sheet bundle 1 is twisted and elastically biased in the push-up direction by the coil spring 76c. Furthermore, as shown in FIG. 29 (C), a rack 76d is formed on a sheet push-up member 76 having a pushing surface 76a, a gear 76e is engaged with the rack 76d, and the gear 76e is rotated by a motor so that the sheet is rotated. The push-up member 76 may be moved up and down.

  Further, as shown in FIGS. 19 and 20, the sheet pressing member 71 described above engages the restricting projection 74 of the punching blade 67 with the movement amount restricting groove 73 and presses the one end 73 a, thereby removing the sheet pressing member 71. The sheet 67 is slid in conjunction with the blade 67. As shown in FIGS. 30A and 30B, the sheet pressing member 71 is interlocked with the extraction blade 67 by a drive unit 79 using a motor or the like as a drive source. You may make it slide. In this case, the slide of the punching blade 67 pushed by the handle 12 may be detected by a switch, and the sheet pressing member 71 may be slid by the driving unit 79. Needless to say, the drive unit 79 may be pressed and urged in the pressing direction of the sheet bundle 1 by an elastic body such as a coil spring instead of the motor.

<6-5. Explanation of Press Adhesive Member>
31 (A) to (C) and FIGS. 32 (A) to (C), the punching unit 16 has a winding claw 41 on the upstream side in the insertion direction of the sheet bundle 1 with respect to the punching blade 67. A pressing adhesive member 81 is provided that presses the piece 3 wound around the hole 2 when the sheet bundle 1 is pulled out to securely bond the piece 3 to the sheet bundle 1. This pressing adhesive member 81 is a C-shaped elastic piece, and is provided so as to be elastically displaceable in the arrow J direction with respect to the sheet bundle 1 inserted from the K direction in FIG. That is, the pressure bonding member 81 is provided so that an angle θ formed by the piece on the side for receiving the inserted sheet bundle 1 and the inserted sheet bundle 1 becomes an acute angle, and the sheet bundle 1 can be smoothly moved, that is, with a small force. Can be inserted. On the other hand, when the sheet bundle 1 is pulled out, it is pressed so as to handle the piece 3 wound around the hole 2 by the wedge effect due to the angle of the piece 3 on the side for receiving the inserted sheet bundle 1. Yes. In the pressing adhesive member 81, the contact portion 81a with the sheet bundle 1 is also formed in an arc shape so that the surface of the sheet bundle 1 or the piece 3 is not soiled. As a result, the tip of the piece 3 is affixed on the one surface 1 a of the sheet bundle 1 so as to overlap the winding start portion of the piece 3.

  As shown in FIG. 17, the punching unit 16 is provided with a pair of sheet feeding rollers 87 and 87 on a rotation lever 86 that is rotatably provided on the insertion side of the sheet bundle 1. As shown in FIG. 36, the pair of sheet feeding rollers 87 and 87 are rotated so as to be separated from the placement surface 65 by lifting the rotation lever 86 when the sheet bundle 1 is inserted. Do not become resistance when inserting. When pulling out the sheet bundle 1, the sheet feeding rollers 87 and 87 are brought into contact with the sheet bundle 1 with the rotating lever 86 lowered as shown in FIG. 1, so that the sheet bundle 1 can be pulled out straight. To. The punching unit 16 is provided with a pressing roller 88 that presses the piece 3 on the passage of the piece 3 wound around the hole 2. Unlike the sheet feeding rollers 87 and 87, the pressing roller 88 is a roller that contacts the sheet bundle 1 when the sheet bundle 1 is inserted or pulled out, and can be inserted straight when the sheet bundle 1 is inserted. Also, it functions as an insertion guide roller for the sheet bundle 1. The pressing roller 88 has substantially the same function as the pressing adhesive member 81, and the punching unit 16 may be provided with both the pressing adhesive member 81 and the pressing roller 88, or only one of them. You may make it provide.

  Note that the pressure bonding member 81 can also be configured as shown in FIGS. That is, in the example of FIGS. 33A to 33C, the press bonding member 81 is formed in a semi-cylindrical shape, and the arcuate surface is a contact portion that contacts the sheet bundle 1. Further, the pressing adhesive member 81 has a guide piece 81b formed on a plane opposite to the arcuate surface. The pressing adhesive member 81 is guided by an inclined guide member 82. The inclined guide member 82 is formed with a guide groove 82a, and a guide piece 81b is engaged with the guide groove 82a. The guide piece 81b is pulled by a coil spring 83 which is an elastic body spanned between the fixed portion 84, and the pressing adhesive member 81 is always elastically biased in the direction of pressing the sheet bundle 1. . As shown in FIG. 33 (A), when the sheet bundle 1 is inserted, the pressing adhesive member 81 can be pushed up smoothly, that is, with a small force. As shown in FIG. 33 (B), the sheet bundle 1 When pulling out, it presses so that the part of the piece 3 wound around the hole 2 may be handled by the wedge effect.

  In the example of FIGS. 34A and 34B, the pressure bonding member 81 is constituted by a roller, and this roller is guided by the inclined guide member 82. The pressing adhesive member 81 is pulled by a coil spring 83 and is always elastically biased in the direction of pressing the sheet bundle 1. As shown in FIG. 34 (A), when the sheet bundle 1 is inserted, the pressing adhesive member 81 can be pushed up smoothly, that is, with a small force. As shown in FIG. 34 (B), the sheet bundle 1 When pulling out, it presses so that the part of the piece 3 wound around the hole 2 may be handled by the wedge effect by the structure of the inclined surface of the inclined guide member 82.

  In the example of FIGS. 35A and 35B, the pressure bonding member 81 is a press mechanism, and is lifted and lowered by a drive unit 85 such as a motor. As shown in FIG. 35A, when the sheet bundle 1 is inserted, it is separated from the placement surface 65 so that it can be inserted smoothly. As shown in FIG. 35 (B), when the sheet bundle 1 is pulled out, the pressure bonding member 81 is lowered to handle the sheet bundle 1 and handles the piece 3 wound around the hole 2. . When trying to elastically press the piece 3 with a pressing roller or the like when the sheet bundle 1 is pulled out, the load when the thick sheet bundle 1 is inserted into the piece winding device 10 has increased. The load at the time of inserting the sheet bundle 1 is reduced, and when the sheet bundle 1 is pulled out after the piece 3 is wound around the sheet bundle 1, the piece 3 can be handled with a load, and peeling of the piece 3 is prevented. be able to.

<6-6. Explanation of relationship between winding claw and sheet pressing member>
As shown in FIG. 31A, before the sheet bundle 1 is inserted, the winding pawl 41 is positioned below the placement surface 65, and the punching blade 67 and the sheet pressing portion 75 are also placed. It is in a state of being separated from the mounting surface 65. When the sheet bundle 1 is inserted from the direction of the arrow K, the sheet bundle 1 is inserted until it abuts against the abutting portions 66 and 66, and thereby the punching position is positioned. At this time, the insertion end of the sheet bundle 1 is pushed up by the push-up member 76 and a gap 80 is formed between the insertion surface 65 and the piece 3 fed from the one-feed mechanism 14 can enter.

  When the handle 12 is rotated, as shown in FIG. 31B, first, the piece 3 is sent out from the discharge portion 31 of the one-side feed mechanism 14. The piece 3 is inserted below the one surface 1a with the adhesive layer 4 facing the one surface 1a of the sheet bundle 1, but the sheet bundle 1 is pushed up by the sheet push-up member 76, and the placement surface Since a sufficient gap is formed between the sheet bundle 65 and the sheet 3, the sheet 3 is not accidentally stuck to one surface 1 a of the sheet bundle 1 while the piece 3 is being discharged.

  Further, when the handle 12 is rotated, as shown in FIG. 31C, the sheet pressing portions 75 and 75 of the sheet pressing member 71 are lowered to the portion where the push-up member 76 pushes up the sheet bundle 1. The sheet bundle 1 is pressed by the sheet pressing portions 75 and 75 and sandwiched between the push-up member 76 and the sheet pressing portions 75 and 75. Thereby, a part of the piece 3 is securely attached to one surface 1 a of the sheet bundle 1. In conjunction with the operation of the sheet pressing member 71, the punching blade 67 also descends in the direction of the sheet bundle 1 and punches the sheet bundle 1 to form the hole 2. Note that either the lowering operation of the sheet push-up member 76 or the lowering operation of the punching blade 67 may be preceded.

  When the handle 12 is rotated to the bottom dead center and then returns, as shown in FIG. 32A, the winding claw 41 starts to rotate in the direction of the arrow G1 in conjunction with the rotation of the handle 12. At this time, since the punching blade 67 overlaps the lifting / lowering region of the punching blade 67 and the movable region of the winding pawl 41, the punching blade 67 rises before the winding pawl 41 is rotated, so that the winding pawl 41 is rotatable. Then, the winding claw 41 is rotated in conjunction with the rotation of the handle 12 by the rotation mechanism 51 described above. Thereby, the piece 3 stuck to one surface 1a of the sheet bundle 1 is pushed by the tip 41a of the winding claw 41 by the free end not stuck to the one surface 1a of the sheet bundle 1; The end surface 1c of the sheet bundle 1, the other surface 1b of the sheet bundle 1, and the hole end surface 2a of the hole 2 are wound in this order. As shown in FIG. 32 (B), when the winding of the piece 3 is completed, the winding tool 40 reverses and returns to the standby state.

  As shown in FIG. 32C, the handle 12 returns to its original position, and the sheet bundle 1 is pulled out in the direction of the opposite arrow K. Then, the pressing adhesive member 81 presses the piece 3 wound around the hole 2 by a pressing structure such as a wedge effect. Thereby, the piece 3 is stuck on the one surface 1a side of the sheet bundle 1 so as to overlap the portion of the piece 3 that is stuck first. As a result, the piece 3 is wound around the hole 2 by approximately one turn or more.

<7. Operation explanation>
<7-1. Explanation of the operation of the steering wheel>
As shown in FIG. 37, before the sheet bundle 1 is inserted, the handle 12 is in a standby state in which the handle 12 is rotated with respect to the base unit 11 in the direction of arrow A, for example, 45 °. Further, as shown in FIG. 16A, the drilling unit 16 is in a state of being moved to the drilling position. In this state, the sheet bundle 1 is inserted from the direction of the arrow K along the placement surface 65 of the punching unit 16 until it abuts against the abutting portions 66 and 66 shown in FIG. At this time, when the sheet bundle 1 is inserted, the rotation lever 86 is lifted by the user as shown in FIG. Further, as shown in FIG. 31A, the pressure bonding member 81 is provided such that an angle θ formed between the piece 3 on the side for receiving the inserted sheet bundle 1 and the inserted sheet bundle 1 is an acute angle. Therefore, it can be inserted smoothly, that is, with a small force. Further, as shown in FIG. 31A, the inserted sheet bundle 1 is pushed up by the sheet push-up member 76, and a gap is formed between the sheet stack 1 and the piece 3 fed out from the piece feeding mechanism 14. Is ready to enter.

  As shown in FIG. 38, when the handle 12 starts to rotate in the direction of the counter arrow A, as shown in FIG. 7, the first member 37a and the second member 37b of the one-feed mechanism 14 for feeding the piece 3 are moved. The feed member 37 that is rotatably connected starts to rotate around the support shaft 37c when the tip of the first member 37a is pressed against the inner surface of the handle 12. Further, as shown in FIG. 39, when the handle 12 is rotated, the first member 37a rotates about the support shaft 37c with respect to the second member 37b against the biasing member 38. . Then, as shown in FIG. 6B, the engaging member 36 connected via the second member 37b moves in the direction of arrow B, thereby feeding and feeding one piece 3. . As a result, in the piece 3, the adhesive layer 4 faces the one surface 1 a of the sheet bundle 1 in the gap 80 between the sheet bundle 1 pushed up by the sheet push-up member 76 from the discharge portion 31 and the placement surface 65. And then discharged.

  As shown in FIG. 7, the feeding operation of the engaging member 36 stops when the second member 37 b hits the support shaft 22 that is a stopper. When the handle 12 is further rotated, the operation moves to a punching operation for forming the hole 2 in the sheet bundle 1. At this time, the first member 37 a abuts against the support shaft 22 serving as a stopper, Thereafter, the second member 37b further rotates around the support shaft 37c with respect to the first member 37a against the urging force of the urging member 38. Thereby, when the handle | steering-wheel 12 rotates further, the piece winding apparatus 10 can transfer to punching operation | movement.

  As shown in FIG. 40, when the handle 12 is further rotated, the other end 67a of the punching blade 67 is pressed by the punching blade pressing portion 70 on the inner surface of the handle 12, and the punching blade 67 Is slid to the arrow I that punches out. In the example shown in FIG. 40, a large number of thick sheet bundles 1 as the maximum number are inserted, and the cutting edge of the punching blade 67 is in contact with the sheet bundle 1. Further, when the handle 12 is rotated, as shown in FIG. 41, the restricting projection 74 of the punching blade 67 presses the one end 73a of the movement amount restricting groove 73 of the sheet pressing member 71 in the I direction (FIG. 19 and FIG. 19). FIG. 20). Thus, in conjunction with the punching operation of the punching blade 67, the sheet pressing member 71 also slides in the same direction as the punching blade 67 sliding in the punching direction. Further, when the handle 12 is further rotated, as shown in FIG. 42, the punching blade 67 penetrates the sheet bundle 1 and punches the hole 2 in the sheet bundle 1.

  As shown in FIG. 43, when the handle 12 is rotated to the bottom dead center, the sheet pressing portions 75 and 75 of the sheet pressing member 71 sandwich the sheet bundle 1 with the sheet lifting member 76 on both sides of the punching blade 67. . At this time, both sides of the punching blade 67 of the sheet bundle 1 supported by the die 67b are pressed against the sheet pressing portions 75, 75 and sink against the pressing force of the sheet pressing member 76 (FIG. 22). And FIG. 23). Thereby, the adhesive layer 4 of the piece 3 located on both sides of the sheet pressing portions 75 and 75 is firmly attached to one surface 1a of the sheet bundle 1 (first bonding step). As shown in FIG. 44, when the handle 12 starts to rise from the bottom dead center, the handle 12 is slightly separated from the sheet bundle 1 by the urging force of the elastic body 68.

<7-2. Explanation of steering wheel return path>
Incidentally, the winding tool 40 of the winding mechanism 15 does not rotate during the period from when the handle 12 shown in FIG. As shown in FIGS. 12A and 12B, the rack link member 54 and the rack member 55 do not slide in the direction of the arrow F2, and the engaging portions 44, 44, 44 of the winding tool 40 are first to third. This is because the winding tool 40 engaged and connected to the engaging recesses 55c, 55d, and 55e does not rotate in the G1 direction.

  As shown in FIGS. 13A and 13B and FIG. 15, when the handle 12 is lifted from the bottom dead center, the arcuate gear 52 of the handle 12 moves in the direction D <b> 2 to mesh with the arcuate gear 52. The driving gear member 53 is rotated in the E2 direction, the driving pin 53b of the driving gear member 53 presses the first engagement piece 54a, and the rack member 55 integrated with the rack link member 54 is moved in the direction of arrow F2. Slide to. Thereby, first, the first engaging portion 44 engaged with the first engaging recess 55c of the rack member 55 is pushed, and the winding tool 40 rotates in the arrow G1 direction. Next, when the second engagement portion 44 is engaged with the second engagement recess 55d and the second engagement portion 44 is pushed, the winding tool 40 further rotates in the direction of the arrow G1. Further, the third engaging portion 44 engages with the third engaging recess 55e, and the third engaging portion 44 is pushed, so that the winding tool 40 further rotates in the arrow G1 direction. Thus, the winding claw 41 of the winding tool 40 rotates in the direction of the arrow G1 when the handle 12 is raised, presses the free end of the piece 3 with the tip end portion 41a, and the piece 3 becomes the end surface 1c of the sheet bundle 1, the sheet The other surface 1b of the bundle 1 and the hole end surface 2a of the hole 2 can be wound in this order.

  This will be explained together with the operation of the handle 12. As shown in FIG. 45, when the handle 12 rotates in the direction of arrow A from the state shown in FIG. 44, it engages with the first engaging recess 55c of the rack member 55. The first engaging portion 44 is started to be pushed, and the winding claw 41 of the winding tool 40 starts to rotate in the arrow G1 direction. Next, as shown in FIG. 46, in order to avoid interference between the leading end portion 41a of the winding claw 41 and the punching blade 67 penetrating the sheet bundle 1, the punching blade 67 is moved by the restoring force of the elastic body 68. Slide in the opposite direction of arrow I and retract from the sheet bundle 1. The winding claw 41 is configured to wind the piece 3 around the hole 2 by entering the hole 2 of the sheet bundle 1 perforated by the punching blade 67. If the punching blade 67 does not retract, the tip 41a is connected to the punching blade 67. Because it collides.

  Further, when the handle 12 rotates in the direction of arrow A, as shown in FIG. 47, the rotating winding claw 41 rotates while lifting the piece 3, and its inner circumferential pressing surface 41 b is on the insertion end side of the sheet bundle 1. It contacts the end face 1c (see FIG. 3). Further, when the handle 12 rotates in the direction of arrow A, as shown in FIG. 48, the tip 41a of the wound claw 41 enters the hole 2 so that the free end of the piece 3 is pushed into the hole 2 (FIG. 8). (See (C)). Thus, the winding claw 41 pushes the piece 3 attached to the surface 1a on the upper surface 23 side of the sheet bundle 1 while pressing the end surface 1c of the sheet bundle 1, the other surface 1b of the sheet bundle 1, and the hole 2 It winds in order of the end surface 2a. At this time, the inner peripheral pressing surface 41b in the middle of the inner peripheral surface of the winding claw 41 presses the position of the hole end surface 2a, so that the adhesive layer 4 of the piece 3 is attached to the hole end surface regardless of the number of sheet bundles 1. 2a can be pressed (second bonding step).

  Further, when the handle 12 is rotated in the direction of arrow A, the winding claw 41 starts to rotate in the direction of arrow G2, as shown in FIG. Specifically, as shown in FIG. 14, the rack member 55 slides in the direction of the arrow F1, and the engaging portions 44, 44, 44 of the winding tool 40 are second engaged in order from the third engaging recess 55e. The recess 55d engages with the first engagement recess 55c. Thereby, the winding tool 40 rotates in the arrow G2 direction, and returns to the standby position below the upper surface 23 from the position where the piece 3 is wound, as shown in FIG. In this state, the handle 12 returns to the initial standby position. Thereafter, the sheet bundle 1 is pulled out in the opposite arrow K direction as shown in FIG. Then, the pressure bonding member 81 presses the piece 3 wound around the hole 2 by the wedge effect. The piece 3 is also pressed by the pressing roller 88 (see FIG. 17). Thereby, the piece 3 is stuck on the one surface 1a side of the sheet bundle 1 so as to overlap the portion of the piece 3 that is stuck first (third bonding step). As a result, the piece 3 is wound around the hole 2 by approximately one and a half rounds.

  As described above, when the piece winding device 10 winds the piece 3 around the sheet bundle 1 having the hole 2, the end portion 41 a of the winding claw 41 pushes the free end of the piece 3 from the end side of the sheet bundle 1. When the winding claw 41 is rotated so as to move to the hole 2 of the sheet bundle 1, the piece 3 attached to one surface 1 a of the sheet bundle 1 is moved from one surface 1 a of the sheet bundle 1 to the other. Since the sheet 3 is wound over the surface 1b, inserted into the hole end surface 2a from the other surface 1b of the sheet bundle 1, the piece 3 is wound around the sheet bundle 1 having the hole 2, and the piece is wound over the four surfaces. 3 can be firmly wound around the sheet bundle 1.

  In addition, when the handle 12 is turned, the single-winding device 10 also rotates the winding tool 40 having the winding pawl 41 in conjunction with the sliding of the punching blade 67 pressed by the handle 12, And wound around the hole 2 of the sheet bundle 1. That is, since the operation of the punching blade 67 and the operation of the winding tool 40 are interlocked during the rotation of the handle 12, the hole 2 can be drilled at an accurate position and the piece 3 can be accurately wound around the hole 2. it can. Further, in a series of turning operations of the handle 12, the punching operation and the winding operation of the piece 3 can be performed, and the operability can be improved. If the sheet bundle 1 moves after the punching operation, the operation for winding the piece 3 may not be performed. However, according to this configuration, the sheet bundle 1 does not move after the punching operation. The position of the hole 2 and the winding position of the piece 3 are not shifted, and when the piece 3 is wound, it is possible to prevent the piece 3 inserted into the hole 2 of the shifted sheet bundle 1 from colliding and jamming. .

<8. Sheet holding mechanism>
As shown in FIGS. 26A and 26B and FIGS. 27A and 27B, the sheet pressing portions 75 and 75 of the sheet pressing member 71 have the lowest point set below the sheet bundle 1. As shown in FIG. 27A, when a large number of thick sheet bundles 1, which is the maximum number, are inserted, the maximum load is applied at the lowest point. Then, as shown in FIG. 26 (B), the sheet pressing portions 75 and 75 once descend to the lowest point, and then retract to a position where no load is applied to the sheet bundle 1 following the return path operation of the handle 12. To do. As shown in FIG. 27B, in the case of a large number of thick sheet bundles 1, the sheet bundle 1 just contacts the pressing surfaces of the sheet pressing portions 75 and 75.

  The operation of the sheet pressing member 71 is controlled by a sheet pressing and holding mechanism 91 as shown in FIGS. As described above, the sheet pressing member 71 constituting the sheet pressing and holding mechanism 91 slides in conjunction with the operation of the punching blade 67, as shown in FIGS. 51 (A) and 51 (B) and FIG. In addition to the sheet pressing portions 75 and 75 as described above, the pressing protrusion 92 that presses the holding member 94 is provided. Further, the sheet pressing member 71 is provided with a control projection 93 that controls the holding member 94 to slide in the direction of the opposite arrow I that is separated from the sheet bundle 1.

  The sheet pressing and holding mechanism 91 further includes a holding member 94 that locks the slide of the sheet pressing member 71. The holding member 94 is rotatably attached to the slide base 61 by a support shaft 94a. The holding member 94 is switched between the position shown in FIG. 52 and the position shown in FIG. 53 by a switching member 95 made of an elastic body such as a coil spring. The switching member 95 has one end locked to the slide base 61 and the other end locked to the holding member 94. Further, the holding member 94 is formed with a pressed portion 96 that is pressed by the pressing protrusion 92 of the sheet pressing member 71. Further, the holding member 94 is formed with an engaging step portion 97 with which the control protrusion 93 of the sheet pressing member 71 is brought into contact.

  As shown in FIG. 52, when the handle 12 is in the standby state, the sheet pressing member 71 is elastically urged in the counter arrow I direction by the elastic body 68 together with the punching blade 67. At this time, the holding member 94 is urged to rotate in the direction of the arrow L by the switching member 95 around the support shaft 94 a, and the pressing protrusion 92 of the sheet pressing member 71 is pressed by the pressed portion 96 of the holding member 94. It is in the state separated from.

  When the handle 12 is rotated and the punching blade 67 punches the sheet bundle 1 (see FIGS. 26A and 26B and FIGS. 27A and 27B), it slides in the direction of arrow I together with the punching blade 67. The sheet pressing member 71 presses the pressed portion 96 of the holding member 94 with the pressing protrusion 92. Then, as shown in FIGS. 52 and 53, the holding member 94 rotates in the counter arrow L direction around the support shaft 94a. Then, the control protrusion 93 of the sheet pressing member 71 is positioned slightly below the engagement step portion 97 of the holding member 94. As shown in FIGS. 26A and 26B, when the number of sheet bundles 1 is small, only the gap 97a between the control projection 93 and the engaging step portion 97 has a rattling, and the sheet is pushed up. By the member 76, the sheet bundle 1 is pushed up toward the sheet pressing portions 75, 75, and in this state, the sheet bundle 1 is lightly pressed.

  As shown in FIGS. 27A and 27B, when the maximum number of sheet bundles 1 are inserted, the control projection 93 of the sheet pressing member 71 is engaged with the holding member 94 as shown in FIG. The sheet bundle 1 is pushed up to the extent that it abuts against the stepped portion 97, and the sheet bundle 1 is pressed in this state.

  When the handle 12 is raised in the return path, the release piece 98 of the handle 12 kicks up the engaging protrusion 99 of the holding member 94 as shown in FIG. Then, the holding member 94 is rotated in the arrow L direction by the urging force of the switching member 95, and returns to the initial state of FIG. When the number of sheets is small or large, that is, when the thickness of the sheet bundle is thin or thick, it is impossible to insert the piece 3 into the hole 2 of the sheet bundle 1 unless the position of the sheet bundle is in a certain position. Although stable, this configuration allows the height of the other surface of the sheet bundle 1 to be increased regardless of whether the sheet bundle 1 is small or large, that is, whether the sheet bundle 1 is thin or thick. It can be maintained at a fixed position, and the operation when inserting the piece 3 into the hole 2 of the sheet bundle 1 can be stabilized.

<9. Description of Modified Example of Interlocking Operation of Cutting Blade and Sheet Pressing Member>
In the above example, the case where the sliding of the punching blade 67 and the rotation of the winding tool 40 are mechanically interlocked with the rotation of the handle 12 has been described. As shown in FIGS. 56 (A) to (C). The sliding of the punching blade 67 and the rotation of the winding tool 40 may be performed using the motors 101 and 102, and the drive of the motors 101 and 102 may be interlocked by the controller 100. That is, as shown in FIG. 56A, the punching blade 67 is provided with a rack 103 and meshed with a gear 104 connected to the output of the motor 101. The winding tool 40 is also provided with a driving gear 105 and meshed with a gear 106 connected to the output of the motor 102.

  As described above, when electrically sliding the extraction blade 67 and rotating the winding tool 40, the controller 100 places the extraction blade 67 and the winding tool 40 in a standby state as shown in FIG. That is, the punching blade 67 is slid in the direction of the opposite arrow I, and the winding tool 40 is rotated in the direction of the arrow G2 and retracted below the placement surface 65. As shown in FIG. 56B, when punching the sheet bundle 1, the controller 100 drives the motor 101 and slides the punching blade 67 in the direction of arrow I. As shown in FIG. 56C, when the piece 3 is wound, the controller 100 drives the motor 101 in the reverse direction and slides the punching blade 67 in the direction opposite to the arrow I to retract. Thereafter, the controller 100 drives the motor 102 to rotate the winding tool 40 in the direction of the arrow G1 and wind the piece 3 around the hole 2 punched in the sheet bundle 1. The slide operation of the sheet push-up member 76 can be mechanically or electrically interlocked with the slide operation of the punching blade 67.

  Thereafter, the sheet bundle 1 is pulled out in the opposite arrow K direction as shown in FIG. Then, the pressure bonding member 81 presses the piece 3 wound around the hole 2 by the wedge effect. Thereby, the piece 3 is stuck on the one surface 1a side of the sheet bundle 1 so as to overlap the portion of the piece 3 that is stuck first (third bonding step).

<10. Description of Modification of Winding Mechanism>
In the above example, the case where the piece 3 is wound around the hole 2 of the sheet bundle 1 by the winding claw 41 of the winding tool 40 has been described, but the piece 3 is further turned into the hole 2 of the sheet bundle 1 by a plurality of members. You may make it wind. This will be described with reference to FIGS. 57 (A) to (D) and (E) to (H). In FIGS. 57A to 57D and (E) to (H), (A) to (D) have a sheet pressing portion 75, and (E) to (H) have a sheet pressing portion 75. Since there are only differences, there will be a summary below.

  The winding mechanism 111 presses the piece 3 attached to one surface 1a of the sheet bundle 1 and bends substantially perpendicularly along the end surface 1c on the insertion end side of the sheet bundle 1. A lever 112, a second pressing lever 113 for bending the piece 3 bent by the first pressing lever 112 substantially perpendicularly along the other surface 1b of the sheet bundle 1, and a second pressing lever 113 And a third pressing lever 114 for inserting the bent piece 3 into the hole 2.

  Before the piece 3 is wound around the hole 2, as shown in FIGS. 57A and 57E, the first to third pressing levers 112 to 114 are retracted, and the hole 2 is formed in the sheet bundle 1. Then, as shown in FIGS. 57B and 57F, the first pressing lever 112 advances substantially perpendicularly to the one surface 1a, and the piece 3 is moved to one surface 1a of the sheet bundle 1. Are bent substantially perpendicularly to each other and bonded to the end surface 1c on the insertion end side of the sheet bundle 1. Next, as shown in FIGS. 57C and 57G, the second pressing lever 113 advances in a direction substantially perpendicular to the first pressing lever 112, the piece 3 is bent substantially vertically, and the sheet Adhere to the other surface 1b of the bundle 1. Next, as shown in FIGS. 57D and 57H, the third pressing lever 114 advances substantially perpendicularly to the other surface 1b, bends the piece 3 substantially perpendicularly, 2 and bonded to the hole end surface 2a.

  Thereafter, the sheet bundle 1 is pulled out in the opposite arrow K direction as shown in FIG. Then, the pressing adhesive member 81 presses the piece 3 wound around the hole 2 by a pressing structure such as a wedge effect. Thereby, the piece 3 is stuck on the one surface 1a side of the sheet bundle 1 so as to overlap the portion of the piece 3 that is stuck first (third bonding step).

<11. Description of Modified Example of Adhering Pieces to Three Sides>
In the above example, the piece 3 extends over the one surface 1a, the end surface 1c on the insertion end side, the other surface 1b, the hole end surface 2a of the hole 2, and the one surface 1a (five surfaces). Although the case where it was wound was demonstrated, the piece 3 may be wound by 3 surfaces. As shown in FIG. 58A, the piece 3 is temporarily attached on one surface 1a of the sheet bundle 1 so as to extend over the hole 2, and the winding claw 41 rotates in the direction of the arrow G1. Then, the piece 3 on the hole 2 is pressed by the tip portion 41 a to enter the hole 2. As shown in FIG. 58B, when the winding claw 41 is further rotated in the direction of the arrow G1, the piece 3 that has entered the hole 2 is pressed against the other surface 1b of the sheet bundle 1. Thereby, the piece 3 is affixed to three surfaces of the one surface 1a of the sheet bundle 1, the hole end surface 2a of the hole 2, and the other surface 1b.
