Description

  The present invention relates to an apparatus for manufacturing a paper binding tool capable of binding a plurality of paper sheets, and in particular, by performing a forming step on comb-like laminated paper that is continuously supplied, The present invention relates to an apparatus capable of continuously manufacturing a binding tool.

  As means for binding booklets such as calendars and notebooks, metal binding tools formed in a spiral shape or a ring shape have been widely used. However, since the metal binding tools cannot be incinerated, when discarding these booklets, it is necessary to remove the binding tools from the paper booklet body, separate them, and discard them, which is very complicated. Further, the binding tool may be discarded as combustible waste without being removed from the booklet main body, which is problematic from the viewpoint of environmental protection. Therefore, in recent years, a paper binding tool having an advantage that it is possible to incinerate the whole without requiring separation work at the time of disposal has been developed and supplied to the market.

  The paper binding tool is manufactured by an apparatus as described in, for example, Japanese Patent Application Laid-Open No. 2009-119712. In such a conventional paper binding tool manufacturing apparatus, the application process, the interleaf / comb-like cutting process, the half-cut process, and the molding process (primary molding and , Secondary forming) are sequentially executed, whereby a paper binding tool is manufactured.

  More specifically, in the coating step, a pair of strip-shaped (width 45 mm, length several hundred meters) raw papers wound in rolls are successively fed out, and an adhesive (heat seal) is applied to one surface of one raw paper. It is a process to apply adhesive), and the interleaf / comb-like cutting process consists of a pair of (two sheets) raw paper (raw paper coated with heat-seal adhesive and uncoated raw paper) Two layers of comb-like laminated paper (the laminated paper) are laminated by overlapping them continuously, making a comb-like cut into the center of the laminated raw paper (laminated paper), cutting the laminated paper into left and right From the right edge, a comb-like laminated paper composed of a plurality of comb-like parts protruding from the right edge toward the left edge with a predetermined width, and from the left edge and left edge of the laminated paper A process for forming a comb-like laminated paper comprising a large number of comb-like portions protruding with a predetermined width toward the right edge portion) It is.

  The half-cut process is a process in which one raw paper (back side raw paper) is partially removed from two stacked raw papers within a predetermined range (about 5 mm) from the tip of the comb-like portion. In addition, the forming step is a step of bending the comb-like portion into a ring shape by a heated bending die.

  FIG. 6 shows the comb-like laminated paper 80 in a state where the half-cut process is finished. 6 (1) is a plan view of the back side of the comb-like laminated paper 80, (2) is an enlarged view of a cross section taken along line XX shown in (1), and (3) is a back side. Partial perspective view (4) is a partial perspective view of the front side. As shown in the drawing, the comb-like laminated paper 80 is a series of side edges 81 extending along the longitudinal direction, and protrudes from the side edges 81 in a direction perpendicular to the longitudinal direction with a predetermined length. And a large number of comb-shaped portions 82.

  The comb-like laminated paper 80 is formed by superimposing two raw paper sheets through a heat seal adhesive in the interleaf / comb-like cutting step, and therefore, a cross-sectional view of FIG. As shown in FIG. 2, a heat-seal adhesive layer 85 is interposed between the two raw papers (front-side raw paper 83 and back-side raw paper 84). However, in the half-cut process, the back-side raw paper 84 is partially removed from the two raw papers stacked within a predetermined range (about 5 mm) from the tip of the comb-shaped portion 82. At the tip end portion of the tooth-like portion 82, the heat seal adhesive layer 85a is exposed.

  FIG. 7 is a partial perspective view of a paper binding tool 90 manufactured by performing a forming process on the comb-like laminated paper 80 shown in FIG. As shown in the figure, the paper binding tool 90 includes a side edge portion 81 and a large number of ring-shaped portions 91. The ring-shaped portion 91 is processed so as to be curved in a ring shape by performing press molding on the comb-shaped portion 82 shown in FIG.

  In this manufacturing apparatus, raw paper having a length of several hundreds of meters is continuously supplied and processed, and a series of paper binding tools 90 are manufactured. A series of paper binding tools 90 manufactured in this way are discharged from the manufacturing apparatus and wound around a bobbin (the paper binding tool 90 having a length of about 200 m is wound around one bobbin. Or stored as it is or transferred for the next step (bookbinding step).

JP 2009-119712 A

  By the way, when the paper binding tool 90 is manufactured by the conventional manufacturing apparatus as described above, the formation position of the ring-shaped portion 91 is shifted, and the paper binding tool 90 cannot be formed into a uniform shape. May occur. The problem of “shift in the formation position of the ring-shaped portion” is caused when the comb-shaped laminated paper 80 cannot be properly positioned during the primary molding in the first molding portion, or in the second molding portion. This occurs when the comb-like laminated paper 80 is bent during the secondary forming.

  This point will be described in detail. First, in the primary molding step, as shown in FIG. 8 (an explanatory diagram of the operation mode of the first molding unit that performs the primary molding on the comb-like laminated paper 80). Of the straight comb-shaped portion 82, press molding is performed on the base end portion side (side edge portion 81 side). More specifically, the comb-like laminated paper 80 is transferred so that the side edge portion 81 slides on the fixed guide 101, and the comb-like portion 82 is shown in FIGS. The base end side portion of this is pressed by the ascending lower bending die 102 and the descending upper bending die 103 to perform primary molding.

  Each of the lower bending die 102 and the upper bending die 103 incorporates a heater, and presses the comb-like portion 82 while heating. In addition, before the comb-like portion 82 is pressed by the lower bending die 102 and the upper bending die 103, the positioning guide 104 operates to set the comb-like laminated paper 80 at an appropriate position. Molding is performed.

  When the comb-shaped laminated paper 80 is supplied to the first molding unit, the comb-shaped laminated paper 80 is moved in three directions (left and right outer sides) by a hook-shaped guide (not shown) up to the position immediately before the first molding unit. , And the lower side) are controlled in an appropriate orbital state, but in the first molding part, finally, as shown in FIG. Since the tip side of the portion 82 is bent downward, guides cannot be arranged on the tip side and the lower side of the comb-like portion 82, and in a conventional manufacturing apparatus, as shown in FIG. In addition, only the fixed guide 101 that restricts the outer side and the lower side of the side edge 81 is disposed.

  For this reason, as shown in FIG. 8 (1), the comb-like laminated paper 80 is displaced in a direction away from the fixed guide 101 when it is supplied to the first molding unit, and the side edge portion 81 and the fixed guide 101. A gap may be formed between the ridge portion 101a. If press molding is performed in this state, the formation position of the ring-shaped portion 91 (see FIG. 7) is shifted, and the paper binding tool 90 cannot be made into a uniform shape. As a result, in the bookbinding process When the ring-shaped portion 91 is automatically attached to the binding hole of the paper sheet, a problem occurs.

  In order to avoid such a problem, in the first molding portion, the positioning guide 104 is inserted into the comb-like laminated paper 80 before the comb-like portion 82 is pressed by the lower bending die 102 and the upper bending die 103. Is moved to the fixed guide 101 side, the gap between the side edge portion 81 and the ridge portion 101a of the fixed guide 101 is eliminated, and the comb-like laminated paper 80 is positioned and then bent downward. Press molding by the mold 102 and the upper bending mold 103 is performed.

  However, since the comb-like laminated paper 80 supplied to the first molding unit is made of paper, the external factor, humidity, or other reasons at the time of manufacture, transfer, or storage, Deformations such as “warping” and “breaking” may occur. In this case, as shown in FIG. 9, even if the positioning guide 104 moves to the fixed guide 101 side, the comb-like laminated paper 80 cannot be sent to the fixed guide 101 side, and positioning cannot be performed properly. As a result, as described above, the formation position of the ring-shaped portion 91 is shifted, and the paper binding tool 90 cannot be formed in a uniform shape.

  Further, in the secondary forming step, the comb-like laminated paper 80 processed in the state shown in FIG. 8 (3) in the first forming part is sequentially transferred to the second forming part, and the comb-like part The press molding is performed so that 82 finally becomes a ring shape (ring-shaped portion 91) as shown in FIG. 7, and the comb-like laminated paper that has entered the second molded portion during the secondary molding is performed. Reference numeral 80 denotes a curved portion processed by primary molding (primary curved portion) and the side edge portion 81 should be pressed in a state where the side edge portion 81 is in close contact with the fixed guide. In this case, the formation position of the ring-shaped portion 91 is shifted, and the paper binding tool 90 cannot be formed in a uniform shape.

  The present invention has been made to solve such problems of the prior art, and the comb-like laminated paper supplied to the first molding part has been deformed such as “warping” and “folding”. Even in this case, the positioning performed immediately before the primary molding can be properly executed, the occurrence of bending in the comb-like laminated paper in the second molding portion can be prevented, or the bending can be eliminated, Accordingly, an object of the present invention is to provide a paper binding device manufacturing apparatus that can suitably avoid the problem of product defects based on a shift in the formation position of the ring-shaped portion.

  The paper binding device manufacturing apparatus according to the present invention includes a series of side edges extending along the longitudinal direction, and a plurality of comb teeth protruding from the side edges in a direction perpendicular to the longitudinal direction with a predetermined length. Side combs and a plurality of ring-shaped parts by performing primary molding in the first molding part and then secondary molding in the second molding part. The first forming unit has a fixed guide, a lower bending die, an upper bending die, a positioning guide, and an upper guide, and the positioning guide is a comb tooth. After the comb-like laminated paper is positioned by operating to feed the sheet-like laminated paper to the fixed guide side, the comb-tooth shape of the comb-tooth-like laminated paper by the ascending lower bending mold and the descending upper bending mold The primary molding is performed by pressing the part on the base end side of the part. A lower flap is formed at the lower portion of the positioning guide to restrict the tip portion of the comb-like portion of the comb-like laminated paper entering the first molding portion from being positioned below the positioning guide. The guide is disposed above the comb-like portion of the comb-like laminated paper entering the first forming portion, and is configured to restrict the tip portion of the comb-like portion from being positioned above the positioning guide. It is characterized by having.

  When the comb-like laminated paper enters the first molding part, the positioning guide is stopped at a position where the lower flap is below the comb-teeth part, And when press molding is performed by the upper bending die, it is preferable to be configured to retract to a position where it does not interfere with the comb-tooth-shaped portion that rotates downward. Moreover, it is preferable that the lower flap of the positioning guide and the end portion of the upper guide are each tapered.

  Furthermore, the moving stage is configured to be movable along the transfer direction of the comb-like laminated paper on the rail, and is attached to the moving stage at a predetermined arrangement interval. A plurality of chucks configured to be capable of gripping a side edge portion of paper or a paper binding tool, and moving from a starting point to a transfer target position, a comb-shaped laminated paper to be supplied is first molded A plurality of chucks, a first chuck that operates in a region in front of the second molding unit, and a first molding unit. And a second chuck that operates in a region between the first molding unit and a third chuck that operates in a region rearward of the first molding unit. Hold the chuck with the second chuck A tension applying device for urging in the opposite direction is arranged, and after the transfer device has moved to the transfer target position, before the secondary forming is performed in the second forming part, the tension applying device is driven, It is preferable that the first chuck is configured to move slightly in the direction opposite to the second chuck so that the distance between the first chuck and the second chuck is increased.

  DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of a paper binding tool manufacturing apparatus according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a configuration diagram of a paper binding device manufacturing apparatus 1 according to the present invention. As shown, the manufacturing apparatus 1 includes a supply-side reel 20, an introduction unit 30, a first molding unit 40, It is comprised by the 2nd shaping | molding part 50, the collection | recovery side reel 60, the transfer apparatus etc. which are not shown in figure.

  In the present embodiment, the comb-like laminated paper 80 (see FIG. 6) wound around the bobbin set on the supply-side reel 20 is sequentially fed out and continuously from the introduction unit 30 into the apparatus main body. Then, primary molding is performed in the first molding unit 40, and then secondary molding is performed in the second molding unit 50, and the paper binding tool 90 (see FIG. 7) is manufactured. Then, the paper binding tool 90 manufactured through the secondary molding is sequentially discharged from the inside of the apparatus main body, and is continuously wound and recovered by the bobbin set on the recovery side reel 60.

  FIG. 2 is a partial perspective view of the first molding portion 40 shown in FIG. 1 (a portion on the introduction portion side), and FIG. 3 is an explanatory diagram of an operation mode of the first molding portion 40. As shown in these drawings, the first molding portion 40 includes a fixed guide 41, a lower bending die 42, an upper bending die 43, a positioning guide 44, and an upper guide 45. The upper guide 45 is for correcting (containing) upward “warping” or “breaking” that may occur in the comb-shaped portion 82. The positioning guide 44 is formed with a lower flap 44a for correcting (containing) a downward “warp” or “break” that may occur in the comb-shaped portion 82.

  In the 1st shaping | molding part 40, the comb-tooth shaped laminated paper 80 is continuously supplied from an introducing | transducing part, The comb-tooth shaped laminated paper 80 which entered into the 1st shaping | molding part 40 is a side edge part. 81 is moved so as to slide on the fixed guide 41. Then, as shown in FIGS. 3 (1) to (3), the positioning guide 44 operates so as to send the comb-like laminated paper 80 to the fixed guide side, and the comb-like laminated paper 80 is positioned. Thereafter, the base end side portion of the comb-shaped portion 82 is pressed by the ascending lower bending die 42 and the descending upper bending die 43 to perform primary molding.

  In the conventional manufacturing apparatus, a heater is incorporated in both the lower bending mold 102 and the upper bending mold 103 (see FIG. 8). However, in the manufacturing apparatus 1 of the present embodiment, the upper bending mold is used. Only the heater 43 is built in 43 and not in the lower bending die 42. In many cases, the comb-like laminated paper 80 is printed with various colors so as to make use of the characteristic of “paper”. However, depending on the type of printing ink, the lower bend die 42 is heated in the primary state. When the molding is performed, there is a problem in that the printing ink peeled off from the comb-shaped laminated paper 80 adheres to the press-contact portion of the lower bending die 42 that contacts the inwardly curved portion of the comb-shaped laminated paper 80. This is to avoid such a problem.

  FIG. 4 is an explanatory diagram of an operation mode of the second molding unit 50 shown in FIG. 1. As shown in the figure, the second molding part 50 is constituted by a fixed guide 51, a lower bending die 52, a pressing die 53, and a lateral bending die 54.

  Comb-like laminated paper 80 that has undergone primary molding in the first molding unit 40 is continuously supplied to the second molding unit 50, and the comb teeth that have entered the second molding unit 50 The laminated sheet 80 is transferred so that the curved portion (primary curved portion 82 a) and the side edge 81 of the comb-shaped portion 82 processed by primary molding slide on the fixed guide 51. .

  Then, as shown in FIGS. 4A and 4B, the comb-shaped portion 82 is clamped and fixed with the fixed guide 51 by the pressing mold 53 that descends, and then moved laterally (FIG. 4). By the lateral bending die 54 that moves toward the fixed guide 51 from the position shown in (1) to the position shown in (2), the comb-tooth shaped portion 82 is curved to the extent that the comb-shaped portion 82 is wound about 70% around the fixed guide 51. Finally, the tip portion of the comb-like portion 82 is processed to bend and bend by the ascending lower bending die 52, and the paper binding tool 90 having the shape as shown in FIG. 7 is manufactured. .

  FIG. 5 is an explanatory diagram of an operation mode of the transfer device 71 arranged in the paper binding tool manufacturing apparatus 1. The transfer device 71 transfers the comb-like laminated paper 80 supplied from the supply-side reel 20 from the introduction unit 30 to the first molding unit 40, and further transfers from the first molding unit 40 to the second molding unit 50. As shown in the figure, the movable stage 73, the first chuck 74, the second chuck 75, and the third chuck 76 are configured.

  The moving stage 73 is configured to be movable along the transfer direction of the comb-like laminated paper 80 on the rail 72, receives a driving force output from a driving force source (such as a ball screw) (not shown), and receives a predetermined force. It is configured to reciprocate within the range. The first chuck 74, the second chuck 75, and the third chuck 76 are attached to the moving stage 73 with a predetermined arrangement interval, and at each tip portion, comb-like laminated paper 80 (paper binding tool). 90) can be grasped.

  The first chuck 74 operates in a region in front of the second forming unit 50 (the comb-like laminated paper 80 or the paper binding device 90 on the transfer destination side, the left side shown in FIG. 5), and the second chuck 75 The third chuck 76 operates in a region behind the first molding unit 40 (on the introduction unit 30 side), and operates in a region between the first molding unit 40 and the second molding unit 50.

  In the transfer device 71, the three chucks 74, 75, and 76 of the comb-like laminated paper 80 are located at the position (origin) (position where the first chuck 74 is close to the second molding unit 50) shown in FIG. The side edge is gripped, and in this state, it moves to the position (transfer target position) (position where the second chuck 75 is close to the second forming portion 50) shown in FIG. Move 80 forward. As a result, the unprocessed comb-like laminated paper 80 enters the first molding unit 40, and the comb-like laminated paper 80 subjected to the primary molding in the first molding unit 40 enters the second molding unit 50. Enters.

  Then, after the primary molding is performed in the first molding unit 40 and the secondary molding is performed in the second molding unit 50, the transfer device 71 (chucks 74, 75, 76) The paper binding tool 90) is released, moved to the position shown in FIG. 5 (1), and returned to the origin. Thereafter, by repeating this operation in the transfer device 71, the comb-like laminated paper 80 is continuously transferred forward, and the paper binding tool 90 is continuously manufactured.

  The manufacturing apparatus 1 for the paper binding tool 90 according to the present embodiment has the above-described configuration. As shown in FIG. 9, the comb-like portion 82 of the supplied comb-like laminated paper 80 is used. Even when the “warping” or “folding” occurs, the positioning performed immediately before the press molding can be properly performed in the first molding unit 40, and the second molding unit 50 can Can prevent the occurrence of bending in the comb-like laminated paper 80, or can preferably eliminate the generated bending, thereby favoring the problem of product failure based on the deviation of the formation position of the ring-shaped portion, etc. Can be avoided.

  This point will be described in detail. First, in the conventional manufacturing apparatus, as shown in FIG. 8, only the fixed guide 101 that regulates the outside and the lower side of the side edge portion 81 is arranged, and the comb is arranged. In the tooth-like portion 82, when “warping” or “folding” as shown in FIG. 9 occurs, even if the positioning guide 104 moves to the fixed guide 101 side, the comb-like laminated paper 80 is fixed to the fixed guide 101. There is a problem in that it cannot be sent to the side, and positioning cannot be performed properly.

  In the manufacturing apparatus 1 of the present embodiment, a lower flap 44 a is formed at the lower part of the positioning guide 44, and the tip portion of the comb-like portion 82 is restricted from being positioned below the positioning guide 44. In addition, the upper guide 45 is disposed above the comb-shaped portion 82 of the comb-shaped laminated paper 80 that enters the first molding portion 40, and the tip of the comb-shaped portion 82 is located above the positioning guide 44. Since the positioning is restricted, the tip portion of the comb-like portion 82 is always positioned even when the “warping” or “folding” as shown in FIG. Thus, positioning by the positioning guide 44 is performed properly.

  In the positioning guide 44, when the comb-like laminated paper 80 enters the first molding portion 40, the lower flap 44 a has a comb-teeth portion 82 as shown in FIG. 3 (1). When the press molding is performed by the lower bending die 42 and the upper bending die 43, as shown in FIG. 3 (3), the comb teeth are rotated downward. Retracts to a position where it does not interfere with the shaped portion 82.

  In addition, as shown in FIG. 2, the lower flap 44a of the positioning guide 44 and the end portion on the introduction portion side of the upper guide 45 are each tapered (inclined in a direction extending up and down toward the introduction portion side). ). For this reason, the problem that the comb-tooth-shaped portion 82 in which the downward “warping” or “folding” occurs enters the lower side of the lower flap 44a, or the upward “warping” or “folding”. The problem that the comb-tooth shaped portion 82 in which the dent has occurred collides with the upper guide 45 and is damaged or the supply of the comb-toothed laminated paper 80 is stopped due to being caught by the upper guide 45 is preferably avoided. It can be done.

  Further, in the manufacturing apparatus 1 of the present embodiment, a tension applying device 77 that urges the first chuck 74 in a direction opposite to the second chuck 75 is disposed between the first chuck 74 and the moving stage 73. After the transfer device 71 has moved to the transfer target position shown in FIG. 5B, the tension applying device 77 is driven before the secondary molding is performed in the second molding unit 50. Has been. When the tension applying device 77 is driven, the first chuck 74 slightly moves in the direction opposite to the second chuck 75, and the interval between the first chuck 74 and the second chuck 75 is widened. As a result, tension is applied to the comb-like laminated paper 80 held by the chucks 74 and 75, and the bending is eliminated.

  Note that when the tension is applied by the tension applying device 77, the pressing mold 53 shown in FIG. 4 is lowered, and the primary curved portion 82a and the side edge 81 of the comb-like laminated paper 80 are connected to the pressing mold 53, the fixed guide 51, and the like. It is released after being pinched between and fixed. Then, after the tip end portion of the comb-like portion 82 is processed by the lateral bending die 54 and the lower bending die 52, the three chucks 74, 75, and 76 are comb-like laminated paper 80 (paper binding tool 90). ) Is released to return to the origin position shown in FIG.

  As a result of performing the secondary forming in this way, the bending occurring in the longitudinal direction of the comb-like laminated paper 80 is eliminated, the shift of the formation position of the ring-shaped portion 91 is avoided, and the paper binding tool 90 having a uniform shape is obtained. Can be manufactured.

  In the present embodiment, the tension applying device 77 that applies tension to the comb-like laminated paper 80 is disposed between the first chuck 74 and the moving stage 73, but the second chuck 75 and the moving stage are arranged. You may make it arrange | position between 73. In this case, the tension applying device 77 is configured such that the second chuck 75 moves in a direction opposite to the first chuck 74 in the driving state. Further, the tension applying device 77 does not need to be configured as an independent element separate from the moving stage 73, and the moving stage 73 partially expands and contracts so that the distance between the first chuck 74 and the second chuck 75 is increased. You may comprise so that it may spread.

  As described above, the paper binding tool manufacturing apparatus 1 according to the present embodiment executes only the molding process on the separately manufactured comb-like laminated paper 80 (see FIG. 6), and performs the paper binding. Although it is configured as an apparatus for manufacturing the tool 90 (see FIG. 7), an apparatus for performing an adhesive application process on the supplied raw paper, an interleaf / comb-tooth shape, in the preceding stage of the manufacturing apparatus 1 By arranging a device that performs the cutting process and a device that performs the half-cut process, it can be implemented as a paper binding tool manufacturing apparatus that consistently performs from the coating process to the molding process. A device for performing a bookbinding process for automatically attaching the paper binding tool 90 to the booklet body and bonding the tip of the ring-shaped portion 91 to the side edge portion 81 is disposed at the subsequent stage of the manufacturing apparatus 1. From the application process of adhesive to raw paper Up step can also be implemented as a bookbinding device which performs consistently.
