Description

  The present invention relates to a binding device for binding pieces using a paper material used for binding a plurality of paper pieces without using a metal needle, and a binding method thereof.

Conventionally, when binding a plurality of pieces of paper (hereinafter referred to as paper) that are not too thick, a simple binding device called a stapler (hereinafter referred to as a stapler) has been used exclusively. In this instrument, a plurality of sheets are integrated and bound by inserting metal binding needles having a U-shaped cross section into a plurality of sheets and bending the penetrating tip portion in a substantially orthogonal direction.
JP2002-210675A JP2003-236267

  The stapler having such a configuration is widely and generally used, but since a metal binding needle is used, its existence sometimes becomes a problem. For example, even when trying to crush a plurality of sheets that are no longer necessary with a shredder, the shredder blade is damaged if the binding needle is still attached, and it is necessary to remove 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 development of a method for binding a plurality of sheets without using a metal needle has been strongly desired.

  Therefore, prior to this application, the inventor invented a method of binding a plurality of sheets without using a metal needle and an apparatus therefor, and proposed in Japanese Patent Application No. 2004-22586.

  It is an object of the present invention to provide a binding device for a binding piece using a paper material and a binding method thereof, in which the ease of use is improved and the complexity of the mechanism is eliminated by subsequent research.

  In order to achieve the above-described object, a binding device according to the present invention is a binding device that integrates a plurality of superposed sheets of paper using a binding piece using a paper material, and includes a pressing portion of the binding piece, and the pressing portion. And a cutting blade that temporarily holds the binding piece and forms a substantially U-shaped, substantially U-shaped or substantially arc-shaped cutting line on the sheet, and includes the pushing portion and the cutting portion. It has a mechanism for linearly moving the blades simultaneously.

  According to the present invention, the cutting blade for forming the cutting line on the paper has a substantially U shape, a substantially U shape, or a substantially arc shape. In contrast, the sheet can be bent along the cutting line in the direction in which the cutting blade enters, and the binding piece can be inserted very easily using the space generated by the bending. Further, only by the linear movement of the binding portion and the cutting blade at the same time, the inserted binding piece can be integrated without coming out of the paper. Initially, for example, when the end of the binding piece was inserted into a sheet on which a substantially arc-shaped cut line was formed, there was a concern that the binding piece would come out of the sheet at the same time as the cutting blade was pulled out. A mechanism to drive independently of the cutting blade was adopted. However, the force that the curved paper returns to the original position and the resistance caused by the friction between the binding piece and the paper combine to cause the inserted binding piece to come out of the paper even after the cutting blade is pulled out. I found that there was no. This makes it possible to reduce the number of parts and eliminate the complexity of the mechanism.

  In the present invention, the paper material that is the material of the binding piece is not particularly limited in paper quality. Not only high-quality paper, which is a general paper material, but also printing paper and information paper can be widely applied. In addition, the paper material used in the present invention includes, for example, a paper material impregnated with a resin or the like. The push-in part may have a simple flat surface, but in order to reduce the weight and prevent the binding piece from sticking to the push-in part due to static electricity or the like, an opening is provided in part. It may be provided, or unevenness such as a bowl-shaped depression may be provided in part or all. As a mechanism for causing the pushing portion and the cutting blade to linearly move at the same time, a mechanism using an elastic body such as a spring or rubber, or a mechanism that is actuated by a pressure medium such as gas or liquid to generate a linear motion is preferable.

  In the binding device according to the present invention, the cutting blade has a first blade that forms a cutting line linearly or arcuately with respect to the paper, and a direction substantially orthogonal to a straight line that connects both ends of the cutting line. And a second blade that forms a score line. With such a cut line, the paper can be easily bent along the cut line in the direction in which the cutting blade enters, and the binding piece is more smoothly inserted into the paper using the space generated by the curve.

  Furthermore, the binding device of the present invention may include a third blade that shears a connecting portion of the binding piece material in which a plurality of binding pieces are connected in a band shape. Considering the standpoint of the user of the binding device, it is not efficient to place each binding piece at a predetermined position of the binding device each time the binding pieces are separated one by one. It can be said that it is a preferable example in operation that a binding piece exists as a binding piece material connected in a band shape, and once the binding piece material is arranged in a binding device, a predetermined number of steps can be saved. In this case, by providing the binding device with a cutting blade that cuts the connecting portion of the binding piece material, the binding piece material can be used after being separated into each binding piece.

  In addition, as for the shape of the cutting blade, it is preferable that at least a part of the cutting edge is formed with a convex portion in any cutting blade of the first blade, the second blade, and the third blade. This makes it possible to more easily and smoothly form the score line formed on the paper. In addition, it is preferable that this convex part is formed in the triangular flat plate shape sharpened toward the front-end | tip, and also a jagged shape may be sufficient. In particular, the first blade is preferably formed in a triangular flat plate shape in which the entire blade edge is pointed toward the tip in order to further exhibit the above-described effects. On the other hand, the third blade can cut the connecting portion of the binding piece material more smoothly if the straight line connecting the cutting edges is inclined along the plane perpendicular to the longitudinal direction of the band of the binding piece material. .

  Further, the binding device according to the present invention includes a guide for bending the end portion of the binding piece penetrating to the back side of the paper by sliding the binding device along the paper. By providing the guide for bending the end of the binding piece, the binding process of the paper can be completed without providing a special or complicated mechanism by simply sliding the binding device along the paper.

  The binding method according to the present invention is a binding method for integrating a plurality of sheets of paper superposed by a binding piece using a paper material, the step of temporarily holding the binding piece, and a cutting blade. A step of forming a substantially U-shaped, substantially U-shaped or substantially arc-shaped cutting line on the paper by entering the paper, and bending the paper along the cutting line in a direction in which the cutting blade enters. And a step of passing the end of the binding piece through the paper using the space generated by the bending, and sliding the binding device along the paper to thereby end the end of the binding piece that has passed through. A step of bending the part.

  The binding method according to the present invention is a binding method for integrating a plurality of sheets of paper superposed by a binding piece using a paper material, wherein a binding portion of the binding piece material in which a plurality of binding pieces are connected in a band shape. A step of shearing and separating as a single binding piece, a step of temporarily holding the binding piece, and a cutting blade entering the paper, thereby making the paper substantially U-shaped, substantially U-shaped or substantially arc-shaped. Forming the cut line of the mold, and curving the paper in the entry direction of the cutting blade along the cut line, and using the space generated by the curve, the end of the binding piece, A step of passing the paper through, and a step of bending the end of the bound binding piece by sliding the binding device along the paper.

  By using the binding device of the present invention, it is possible to integrate the sheets by using paper-binding pieces that are easy to dispose of at the time of disposal and are environmentally friendly. Further, by using the binding device and the binding method of the present invention, the binding piece can be inserted into the paper extremely smoothly and easily.

  Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. 1 and 2 exemplify the configuration of a paper cutting blade 1A that realizes the present invention. FIG. 3B is a diagram illustrating a method of binding a plurality of sheets using the cutting blade 1A. FIG. 4 is an exploded view of each part in the binding device of one embodiment of the present invention, and FIGS. 5A to 5D are cross-sectional views of the binding device assembled by the components shown in FIG. 4 and 5A to 5D show a configuration in which binding pieces connected in a strip shape and wound in a roll shape are arranged in a binding device so as to be easier to understand.

  The illustrated cutting blade 1A is composed of a rectangular flat plate-shaped pushing portion 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 pushing portion 2. In addition, this pushing part 2 points out the part which has a flat surface which can be visually recognized when seeing the raising / lowering mechanism 10 from a bottom face directly. Moreover, this cutting blade 1A cuts and holds the rectangular binding pieces 5... 5 having substantially rectangular comb teeth on both sides in the longitudinal direction of the band as shown in FIG. The both ends 6 of the cut binding piece 5 are passed through the document 7 and used for the purpose of integrating the document 7. 1, 2, and 3 </ b> B, the binding pieces 5 having high elasticity and rigidity are used, and high-quality paper that is excellent in strength and elasticity is used.

  The cutting blade lA is connected to an elevating mechanism 10 using a coil spring 14 as shown in FIG. 4, for example. In the binding operation, first, the upper surface 11 of the elevating mechanism 10 is manually pushed and lowered, and then the elevating mechanism 10 is raised by the restoring force of the coil spring 14 to return to the original position.

  The push-in part 2 is formed in a rectangular shape corresponding to the shape of one binding piece 5, and has a short side and a long side almost equal to one binding piece 5. The long side of the binding side 5 is bent and held.

  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 8 and 9 are formed on the inner surface of the tip end side of each to form a cutting blade (see FIG. 2B). The taper surface 8 is a portion that cuts the connecting portion 5 </ b> A of the binding piece 5. Further, the taper surface 9 is a portion that forms a cut in the document 7, and on the basis of the taper surface 9, cut lines 7a and 7a are formed in a direction perpendicular to the longitudinal direction of the binding pieces 5. (Refer FIG.1 (b)). In this embodiment, the binding piece 5 is composed of an insertion portion and a non-insertion portion. If the non-insertion portion is rectangular, the binding piece 5 is orthogonal to the boundary line direction between the insertion portion and the non-insertion portion. The cut lines 7a and 7a are formed in the direction, and the cut lines 7b and 7b for one binding piece are formed in the boundary line direction.

  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.

  3B (a) to 3B (c) are drawings for explaining the operation procedure of the cutting blade lA of FIG. A document 7 in which a plurality of sheets are stacked is disposed on the holding portions 51 and 51 of the binding piece main body and faces the cutting blade lA. The holding portion 51 is a member corresponding to the holding portion 51 of the embodiment shown in FIG.

  In this state, the binding pieces 5... 5 connected as shown in FIG. 3A are sent to the cutting blade 1A in the front-rear direction in FIG. 1, and the cutting blade 1A is also lowered manually by lowering the lifting mechanism 10 thereafter. Be lowered. Then, the connecting portion 5A of the binding pieces 5 ... 5 is cut by the taper surface 8 of the cutting blade lA, and the single binding piece 5 is bent by the pushing portion 2 and the inner peripheral surfaces of the side plates 3a and 4a. It is held (FIG. 3B (a)). Although there is a possibility that the binding piece 5 is about to drop, the cutting blade 1A is moved down vigorously, so that the binding piece 5 does not fall.

  When the cutting blade lA is lowered in this way, the front end portions 3a of the left and right side plates of the cutting blade 1A pierce the document 7, and the taper surfaces 12a and 12b cause the document 7 to have a linear cut line 7b (see FIG. 1 (b)) is formed. This cutting line 7b extends in accordance with the lowering of the cutting blade 1A. However, when the lowering of the cutting blade 1A proceeds, another cutting line 7a orthogonal to the cutting line 7b is formed by the tapered surface 9 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. By this operation, the binding piece 5 passes the document cut line 7b (FIG. 3B (b)).

  Subsequently, the cutting blade 1A is raised. At this time, the end 7c that has been pushed down in the document 7 tries to quickly return to the original state by the restoring force, while the binding piece 5 is cut by the cutting line 7b due to the frictional force between the binding piece 5 and the document 7. As a result, the both ends 6 of the binding piece 5 that has once penetrated the document 7 do not slip out of the document 7 (FIG. 3B (c)). Thereafter, the integration of documents is completed by bending the penetrating binding piece end 6 manually or using a bending guide described later.

  In the present embodiment, like the cutting blade 1A in FIG. 1, the blade forming the cut line 7b is formed in a triangular flat plate shape pointed toward the tip, while forming the cut line 7a. The blade has a linear shape parallel to the paper surface of the document, but is not limited to this shape in order to achieve the effects of the present invention. For example, the tips of these two blades may have some irregularities, and the others may be linear in parallel to the paper surface, or may be jagged. Moreover, it is also a suitable example that the front-end | tip of the convex part in an unevenness | corrugation is curled in order to make a human being hard to get damaged.

  Further, in the present embodiment, the blade for cutting the connecting portion of the band-shaped binding pieces 5... 5 uses the tapered surface 8 which is a part of the elevating mechanism 10, but the present invention is not limited thereto. A part of the positioning guide 41 for sending out the preceding one binding piece in the binding piece material as shown in 4 directly under the lifting mechanism 10 may be used as a cutting blade. In any of these cases, as shown in FIGS. 6A and 7A, a part of the blade edge is formed with a convex portion, more specifically, a triangular flat plate pointed toward the tip. It may be a jagged shape as described above. Of course, a shape having a rounded tip is also employed. On the other hand, as shown in FIG. 6B and FIG. 7B, a cutting blade in which a straight line connecting the blade tips is inclined along a plane orthogonal to the longitudinal direction of the band of the binding pieces 5. If these cutting edges shown in the figure are employed, the connecting portion can be more easily cut.

  Note that the binding piece 5 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 thereof, and the binding piece 5 is bent and bonded or adhered to a document. (Hereinafter collectively referred to as adhesion) is also suitable. In addition, it is preferable to apply | coat an adhesive material so that the edge part of the comb-tooth of the binding piece 5 may be included. Accordingly, the folded end portion 6 including the end portion 6 is securely fixed to the back surface of the document.

  Next, according to FIG. 4 and FIGS. 5A to 5D, an embodiment of a binding device that enables continuous document integration using a plurality of binding pieces will be described. In this embodiment, as shown in FIG. 4 and FIG. 5A, the plurality of binding pieces 5 ... 5 are wound in a roll shape at a predetermined position between the upper part 20 and the lower part 50. It is arranged. In addition, the binding piece material 30 arrange | positions the binding piece material 30 by rotating the upper part 20 as shown by the arrow of FIG. The binding pieces 5... 5 of the roll-like binding piece material 30 are manually moved in the direction of the arrow in FIG. Sent. At this time, the binding piece members 5... 5 that were initially flat are supported by the lower guide 51 and move on the upper guide 22. In order to move along the shape of this, it will be bent gradually. In the present embodiment, the upper guide 22 is a molded body having an inner peripheral surface similar to the changing shape of the binding pieces 5... 5, and is an integrally molded product made of metal or plastic. Even if it is not integral, a plurality of molded bodies can be formed side by side as long as they can be bent substantially. Further, the lower guide 51 is a U-shaped spring made of metal or plastic, but this allows the tip of the upper component 20 and the tip of the lower component 50 to be close to each other when integrating documents. It also serves as a

  The processing area 42 is formed by a member 43 having a concave section that stops the positioning guide 41 and the binding pieces 5... 5, and the inner peripheral surface of the space serves as a guide when the elevating mechanism 10 performs a linear motion. Doubles as

  The binding pieces 5... 5 sent to a predetermined position in the processing region 42 are first cut by the taper surface 8 of the cutting blade 1 </ b> A when the lifting mechanism 10 is manually lowered, and then one piece. While holding the binding piece 5 along the inner peripheral surface of the cutting blade 1A, the binding piece 5 is inserted into the document to be bound from the tip of the cutting blade 1A, and the end of the binding piece 5 is penetrated through the document. At this time, the cutting blade 1A also penetrates the document, but since the space region 55 having a sufficient length and width in consideration of the maximum moving distance of the lifting mechanism 10 is provided in the lower part 50, the cutting blade 1A Linear motion is not interrupted. Moreover, since the lower part 50 has sufficient thickness, a human finger etc. are not damaged by the cutting blade 1A.

  Next, the rollers 23 and 53 are moved along the front and back surfaces of the document while the lifting mechanism 10 is manually pushed on the upper surface 11, in other words, the document is held between the upper part 20 and the lower part 50. Slide while rotating clockwise. By this operation, the bent portion including the end portion 6 of the binding piece penetrating the document is bent along the inner peripheral surface of the bending guide 54 in the lower part 50, and the integration of the document is completed. Furthermore, by repeating the above operation, it is extremely efficient because the binding operation can be continuously performed without arranging individual binding pieces on the binding device one by one.
