Description

  The present invention relates to a binding method and apparatus capable of binding a document or the like without using a metal needle.

Conventionally, when binding a document that is not too thick, a simple binding device called a stapler has been used exclusively. In this apparatus, a metal binding needle having a U-shaped cross section is inserted into a document, and a penetrating tip is bent in a substantially orthogonal direction so that the documents are integrated and bound.
JP2002-210675A JP2003-236267

  Staplers having such a configuration are widely used in general, but use of a metal binding needle may cause a problem. For example, even if an attempt is made to crush a document that is no longer needed with a shreter, the shredding blade will be damaged if the binding needle is still attached, which necessitates removing the binding needle one by one. In some cases, the nails may be damaged when the binding needle is removed, or the fingertip may be injured by the binding needle being stuck.

  Further, the binding needle is also an obstacle when reclaiming paper that is no longer needed, and it has been strongly desired to develop a method for binding documents without using a metal needle.

  The present invention has been made in view of these problems, and an object thereof is to provide a method and an apparatus for binding a document without using a metal needle.

  In order to achieve the above object, a binding method according to the present invention is a binding method for integrating a plurality of superposed sheets using a non-metallic binding piece, and temporarily binding the binding piece. And holding the sheet by cutting the sheet into the plurality of sheets by using a cutting blade that forms a substantially U-shaped or substantially arc-shaped cutting line on the sheet. Along the line, the cutting blade is bent in the direction of entry, and by utilizing the space generated by the bending, both ends of the binding piece are passed through the plurality of sheets.

  The binding piece is preferably made of paper or plastic. In addition, the cutting blade forms a first blade that forms a cutting line orthogonal to the length direction of the binding piece, and a cutting line that extends in the length direction of the binding piece from both ends of the cutting line. Typically, it is comprised with the 2nd blade. Here, it is preferable that the first blade is formed in a triangular flat plate shape pointed toward the tip.

  The binding device according to the present invention includes a cutting blade used in any of the methods described above.

  According to each of the above-described inventions, a document can be bound without using any harmful metal needles. In addition, the binding piece can be configured wider than the metal needle, and since various color binding pieces can be prepared, each document can be clearly identified by the difference in the color of the binding piece binding the document. Become.

  Hereinafter, embodiments of the present invention will be described in detail based on examples. 1 and 2 illustrate the configuration of a paper cutting blade 1A that implements the present invention. FIG. 3 is a diagram illustrating a method of binding a document using the cutting blade 1A.

  The illustrated cutting blade 1 </ b> A includes a rectangular flat plate 2, left and right side plates 3, and front and rear side plates 4, and four side plates 3 and 4 are extended perpendicularly to the top plate 3. This cutting blade 1A holds and holds one unit 5 of the rectangular binding pieces 5 ... 5 as shown in FIG. 3A by a connecting portion 5A indicated by a broken line. It is used for the purpose of integrating the document 7 by making both ends 6 penetrate the document 7. The arrows in FIG. 3A indicate the length direction of the binding pieces. In the embodiment shown in FIGS. 1 to 3, a binding piece 5 having high elasticity and rigidity is used, and a piece of paper excellent in strength and elasticity or a thin plastic piece is adopted. Regardless of which material is used, the connecting portion 5A of each binding piece 5 ... 5 is formed to be extremely thin and can be easily cut.

  The illustrated cutting blade 1A is connected to an elevating mechanism (not shown), and is raised after being lowered and returned to its original position during a binding operation. In addition, an opening hole is formed in the center of the top plate 2 of the cutting blade 1A, and a flat presser plate 9 slightly smaller than the top plate 2 (see FIG. 3 (b)) are connected. The presser plate 9 is moved up and down independently of the blade 1 </ b> A according to the lifting operation of the lifting shaft 8.

  The top plate 2 is formed in a rectangular shape corresponding to the shape of the binding piece 5, and has a short side almost equal to the short side of the binding piece 5 and a long side shorter than the long side of the binding piece 5. . Then, the long side of the binding side 5 is held by being bent or bent (in FIG. 3 (b), it is projected).

  The front / rear side plate 4 is formed in an inverted U shape by a short part 4a on the base end side and long parts 4b, 4c protruding from both ends of the short part 4a. However, the short part 4a and the long parts 4b, 4c are formed. Tapered surfaces 10 and 11 are respectively formed on the inner surface of the tip end side to form a cutting blade (see FIG. 2B). The tapered surface 10 is a part that cuts the connecting portion 5 </ b> A of the binding piece 5. Further, the taper surface 11 is a portion that forms a cut in the document 7, and cut lines 7a and 7a are formed in the longitudinal direction of the binding piece 5 based on the taper surface 11 (see FIG. 1B).

  The left right side plate 3 is composed of a main body portion 3a and a triangular tip portion 3b. Then, on the inner surface of the tip portion 3b, two tapered surfaces 12a and 12b are formed along the oblique sides of the triangle to form a cutting blade (FIG. 2 (b)). Note that the two tapered surfaces 12a and 12b meet to form an inclined ridgeline 13.

  FIG. 3B to FIG. 3E are drawings for explaining the operation procedure of the cutting blade 1A of FIG. A document 7 in which a plurality of papers are stacked is disposed on the holding plates 14 and 14 and faces the cutting blade 1A.

  In this state, the binding pieces 5... 5 communicated as shown in FIG. 3A are sent to the cutting blade 1A in the front-rear direction of FIG. . Then, the connecting portion 5A of the binding pieces 5 ... 5 is cut by the taper surface 10 of the cutting blade 1A, and the bottom surface of the presser plate 9 and the side plates 3a, 4a are in a state where the single binding piece 5 is curved or bent. It is hold | maintained with a surrounding surface (FIG.3 (b)). Although there is a possibility that the binding piece 5 is about to fall, the cutting blade 1A is moved down vigorously, so that the binding piece 5 does not fall.

  When the cutting blade 1A is lowered in this way, the leading end portions 3a of the left and right side plates of the cutting blade 1A are pierced into the document 7, and by the taber surfaces 12a and 12b, a straight cut line 7b (see FIG. 1 (b)) is formed. This cutting line 7b extends in accordance with the lowering of the cutting blade 1A. When the lowering of the cutting blade 1A progresses, another cutting line 7a orthogonal to the cutting line 7b is formed by the tapered surface 11 of the front and rear side plates 4. It is formed. Further, in accordance with the formation of the cut line 7a, both ends 7c of the document 7 located inside the cut line 7b are pushed down (FIG. 3C). By this operation, the binding piece 5 passes through the document cut line 7b.

  Subsequently, the cutting blade 1A is raised. At this time, the holding plate 9 is pushed downward and the holding plates 14 and 14 are pushed upward (FIG. 3D). Then, due to the elasticity and rigidity of the binding piece 5, the binding piece 5 spreads left and right, and a document composed of a plurality of sheets is integrated by the binding piece 5 (FIG. 3E).

  In the above description, the documents are integrated only by the elasticity and rigidity of the binding piece 5. However, in order to improve the appearance by making the mounting surface of the binding piece 5 flatter, as shown in FIG. Thus, it is preferable to arrange the pressure receiving plates 15 and 15 in addition to the holding plates 14 and 14 on the lower side of the document. In the case of this embodiment, the paper and the binding piece 5 are pressed by the presser plate 9 and the pressure receiving plate 15, so that the binding piece 5 is reliably deformed into a U-shaped cross section. In addition, by moving the pressure receiving plates 15 and 15 outward in the final stage, the lower surface of the document 7 can also be made flat (FIG. 4E).

  Further, as shown in FIG. 5, the binding piece 5 is a binding piece 5 that is slightly weak in elasticity and rigidity, and an adhesive or a pressure-sensitive adhesive (hereinafter collectively referred to as an adhesive) is applied to the lower surface 5B of the binding piece 5. It is also suitable to bend and adhere or adhere to a document (hereinafter collectively referred to as adhesion).

  FIG. 5 illustrates an operation content when an adhesive is applied to the lower surface 5 </ b> B of the binding piece 5. The operation content is roughly the same as in FIG. 3, but in this embodiment, the holding plates 14 and 14 are finally moved inward to fold the binding piece 5 and press the application surface ( FIG. 5 (d)). Then, the folded binding piece 5 is bonded to the lower surface of the document 7 so that the document can be reliably integrated (FIG. 5 (e)).

  FIG. 6 is a drawing showing still another cutting blade 1B. In this embodiment, one side of the left and right side plates 3 and 3 in FIG. 1 is omitted and the presser plate 9 is omitted. That is, the cutting blade 1B includes a rectangular top plate 2, front and rear side plates 16, 16 formed in an L shape, a left side plate 17, and a right side plate 18. The front / rear side plate 16 is formed in an L shape with a proximal-side short portion 16a and a long portion 16b protruding from one end of the short portion 16a, and the tips of the short portion 16a and the long portion 16b are tabers. Surfaces 10 and 11 are formed. Further, the left side plate 17 has the same configuration as the left and right side plates 3 of FIG. 1, and the right side plate 18 is a rectangular plate and serves to lock the base end 6 b of the binding piece 5.

  FIG. 7 is a view for explaining the operation content of the cutting blade 1B shown in FIG. In the case of this embodiment, in addition to the holding plates 14 and 14 that hold the lower surface of the document 7, a slide plate 19 that slides the upper surface of the document 7 is disposed. Then, after the leading edge 6a of the binding piece 5 passes through the cutting line due to the lowering of the cutting blade 1B (FIG. 7B), first, the right holding plate 14a is moved to the left, and the bent document 7 is stretched. (M1 in FIG. 7C).

  Next, the left holding plate 14 is moved to the right (M2 in FIG. 7C), and the slide plate 19 is also moved to the right with a slight delay (M3 in FIG. 7C). The binding piece 5 is slightly wound by the right movement of the left holding plate 14, and then the slide plate 19 is moved to the right, so that the binding piece is reliably bent and the document is integrated (FIG. 7D). In this embodiment as well, an adhesive may be applied to the lower surface 5B of the binding piece 5.

  FIG. 8 is a perspective view showing still another cutting blade 1C. In this embodiment, the cutting blade 1C is characterized in that it is used from the lower surface of the document 7 toward the upper surface. And it is comprised by the flat top plate 2, the left-right side plates 3 and 3, and the front-and-rear side plates 4 and 4, but unlike the case of FIG. Is formed. Further, the front and rear side plates 4 do not have a short portion on the base end side, and are provided only with the long portions 4b and 4c. Therefore, although the Taber surface 11 exists, the taper surface 10 for cutting the binding pieces 5... 5 does not exist.

  FIG. 9 is a drawing for explaining the operating state of the cutting blade 1C. In this embodiment, prior to the operation of the cutting blade 1C, a step of generating one unit of the binding piece 5 and a step of pressing it against the upper surface of the document 7 are required. In relation to these processes, a pressing plate 21 and upper holding plates 22 and 22 are disposed on the upper surface of the document 7 (FIG. 9A).

  In the state as shown in FIG. 9A, the cutting blade 1C is moved from the lower surface to the upper surface of the document 7 (FIGS. 9B to 9C). Then, after the cutting blade 1C forms a cut line in the document and buys the document 7, both ends 6 and 6 of the binding piece 5 pass through the opening hole 20 (FIG. 9C). After that, when the cutting blade 1C is lowered, both ends 6 and 6 of the binding piece 5 are moved to the lower surface of the document 7 by being guided by the opening hole 20 of the cutting blade 1C (FIG. 9D). Therefore, the left and right holding plates 14, 14 are then moved inward to fold back both ends of the binding piece 5 so that the documents can be integrated reliably (FIG. 9 (e)). In this embodiment as well, an adhesive may be applied to the lower surface 5B of the binding piece 5.

  FIG. 10 is a perspective view showing still another cutting blade 1D. This cutting blade 1D has substantially the same configuration as the cutting blade 1A shown in FIG. 1, but a tooth-shaped circle having a triangular cross section is formed on the inner surfaces of the front and rear side plates 3 and 3. This tooth-shaped circle is formed in a cross-sectional triangle by a ridge line 19a, a distal end line 19b, and a proximal end line 19c, and the first cut line 7b is formed in the document by the distal end lines 19b and 19b. A second cut line 7a is formed by the oblique line 19d.

  11 (a) to 11 (d) are drawings showing the operating state of the cutting blade 1D, and correspond to FIGS. 3 (b) to 3 (e). In FIG. 11, the guide member 23 that guides the raising and lowering of the cutting blade 1 </ b> D is illustrated, but it is needless to say that the guide member 23 is preferably arranged also in other embodiments. In the case of this embodiment, the tooth mold 19 serves to prevent slipping of the binding piece 5, so that the lowering speed of the cutting blade 1 </ b> D is slow, or friction between both ends 6, 6 of the binding piece 5 and the inner surface of the cutting blade is generated. Even if it is weak, there is no possibility that the binding piece 5 falls.

  Although the embodiments of the present invention have been specifically described above, the specific descriptions do not particularly limit the present invention. For example, in each of the drawings, the binding piece 5 is illustrated as being curved in an arc shape. However, it is also preferable that the binding piece 5 is previously provided with a bent portion and bent into a U-shaped cross section.

  Each cutting blade is configured to form a substantially U-shaped cutting line, but is not particularly limited. For example, it is needless to say that a substantially arc-shaped cut line may be formed. Also in this case, the left parenthesis arc “(” and the right parenthesis arc “)” may be formed at both ends of the binding piece so as to face each other, or only one arc may be formed. good. In addition, when providing a substantially arc-shaped cutting line, it is preferable to make both ends of a binding piece into an arc shape.

  In addition, as an adhesive agent, you may use the microcapsule adhesive agent which does not exhibit adhesive force until particle | grains are destroyed by pressurization.

  The present invention can bind a document without using any metal needle, and the binding piece of paper or the like can be configured wider than the metal needle, and various color binding pieces can be prepared. It is possible to provide a document binding method and apparatus in which each document can be clearly identified by the difference in the color of the binding pieces.
