Description

  The present invention relates to a binding mechanism of a binding device that binds a paper bundle such as a document with a paper binding tool, and more particularly to a binding mechanism of a binding device with improved operability.

  Conventionally, a metal stapler has been used as a means for easily binding a bundle of paper. However, when the paper bound with the staples which are metal wires is reused, the mixed staples must be removed. Also, when discarding, it is desirable to separate paper and staples from the viewpoint of environmental protection. When shredding with a shredder, the staples must be removed so as not to damage the blade of the shredder. It takes extra time.

  As a proposal that does not require such labor, a binding device that binds a paper bundle with a paper adhesive tape instead of a metal staple is known (Patent Documents 1 and 2). This binding device uses a paper adhesive tape roll with release paper, and a slider having a clamp plate for sandwiching paper on a paper table similar to a general desktop stapler, an elevating cutter unit, It has.

  A paper adhesive tape roll is a paper adhesive tape with a predetermined length (the length used for a single binding operation) that is continuously pasted on release paper, and its tip extends from the bottom to the top of the paper table. It stands up and is set so that the adhesive surface faces the end surface of the paper on the paper table.

  When the edge of the paper bundle is sandwiched between the clamp plates of the slider and the slider and the paper bundle are slid forward, the end face of the paper bundle comes into contact with the adhesive surface of the adhesive tape.

  Next, when the cutter part is lowered, the pressing member integrated with the cutter part presses the tip of the adhesive tape against the upper surface of the edge of the paper bundle, and the blade of the cutter part moves from the top to the bottom near the edge of the paper bundle. To penetrate.

  And when the front-end | tip of a blade presses an adhesive tape, the rear part of the adhesive tape for the head of 1 time will peel from a release paper. A square hole is provided in the vicinity of the tip of the blade, and the rear part of the peeled adhesive tape enters the square hole by an elastic restoring force and penetrates the blade back and forth.

  Subsequently, when the manual pressing of the cutter unit is released, the cutter unit is lifted by the spring, and the rear part of the adhesive tape caught on the blade is pulled up together with the blade to the upper surface side of the paper bundle through the paper cut hole, and the blade further rises. Then, the rear part of the adhesive tape comes out of the square hole of the blade, and the rear part of the adhesive tape stands up.

Then, when the slider and the paper bundle are moved backward, the rear part of the adhesive tape is rubbed by the roller arranged on the paper table, and the rear part of the adhesive tape is overlapped with the front part of the adhesive tape that is already crimped to the paper bundle. The binding process is completed.

By configuring to engage the shearing portion of the leg, the object of simplifying the operation process of the binding mechanism and improving the ease and speed of the binding process has been achieved.

  FIG. 1 shows the configuration of the binding mechanism of the binding device. Reference numeral 101 denotes a paper binding member bent in advance in a gate shape. This paper binding member is hereinafter referred to as a paper staple. The paper staple 101 includes a pair of legs 103 and 104 that extend downward from the left and right ends of a horizontal crown portion 102. After the right leg 104 is folded inward by a binding mechanism, the left leg 103 is placed inside. The left and right legs 103 and 104 are joined by crimping.

  11 is a comb-shaped die for receiving paper, and grooves (three in FIG. 1) penetrating vertically are arranged in a comb-tooth shape at regular intervals. The grooves may be arranged at unequal intervals. The cutter portion 21 disposed above the comb-shaped die 11 is a gate-shaped member in which cutter blades 23 are attached to both ends of a horizontally long bar 22, and the lower end of the cutter blade 23 is formed in a V shape. The front-rear width of the blade 23 is substantially the same as the front-rear width of the paper staple 101.

  The mutually opposing surfaces of the left and right cutter blades 23 are formed thinner than the lower part with the boundary slightly below the upper and lower middle, and the interval between the opposing thin portions 23a of the left and right cutter blades 23 is When the paper staple 101 is inserted inside the cutter unit 21, the paper staple 101 is held between the left and right cutter blades 23.

  By providing a step on the inner surface of the cutter blade 23, the leg 103 of the paper staple 101 does not buckle during the lowering operation of the cutter blade 23, and smoothly penetrates the paper together with the cutter blade 23. Further, a square hole 24 is formed in the thin wall portion 23a of the cutter blade 23, and when the cutter portion 21 is lowered, a pair of rollers 31 and 32, which are pressing members disposed under the comb-shaped die 11, are removed from the square hole 24. Enter inside. The pressing member is not limited to a roller, and a cam or the like may be used.

  Immediately below the comb-shaped die 11, a comb-shaped punch 41 for coupling the legs 103 and 104 of the paper staple 101 in cooperation with the comb-shaped die 11 is disposed. The comb-shaped punch 41 has a plurality of punch portions 41a corresponding to the number of grooves of the comb-shaped die 11, and the punch portion 41a has a convex curved surface with raised front and rear intermediate portions. The shape of the punch portion 41a And the groove of the comb-shaped die 11, two parallel cuts are formed in the paper per punch portion 41a.

  The pair of rollers 31 and 32 disposed under the comb-shaped die 11 are located on both the left and right sides of the comb-shaped die 11, and the pair of rollers 31 and 32 are symmetrically approached and separated from each other (see FIG. (Not shown) so as to be freely rotatable and approach each other in conjunction with the lowering operation of the cutter unit 21.

  Next, the operation of the binding mechanism will be described. FIG. 2-1 shows an initial stage of the binding process, in which the paper staple 101 is set inside the cutter unit 21, and the paper staple 101 is held by the left and right cutter blades 23 and the paper P to be bound. Is set on the paper table 11.

  In FIG. 2-2, the cutter part 21 descends and the cutter blade 23 penetrates the paper P, and the crown part of the paper staple 101 is pressed against the surface of the paper P and the comb-shaped die 11 by the cutter part 21. Indicates the state.

  Then, as shown in FIG. 2-3, the left and right rollers 31 and 32 enter the inside of the cutter blade 23 through the square holes 24 of the cutter blade 23, and bend the legs 103 and 104 of the paper staple 101 inward. By shifting the movement timing or standby position of the left and right rollers 31, 32 and delaying the movement of one roller (right roller 32 in the example in the figure), the tips of the left and right legs 103, 104 do not collide. The left leg 103 and the right leg 104 are bent in this order, and are folded so that the right leg 104 overlaps the surface of the left leg 103.

  Next, as shown in FIG. 2-4, the comb-shaped punch 41 is raised, and the overlapping leg portions 103 and 104 are pressed by the comb-shaped punch 41 and the comb-shaped die 11 to partially press the leg portions 103 and 104. Shearing is performed, and the leg 104, which is one leg, is engaged with the shearing part of the leg 103, which is the other leg, so that the legs 103, 104 are coupled. Thereafter, as shown in FIG. 2-5, the comb-shaped punch 41 descends, the left and right rollers 31 and 32 return to the initial position, the comb-shaped die 11 is retracted in the depth direction of the paper surface in the drawing, and the cutter unit 21 is Ascend to release the paper staple 101 and the paper P.

  FIG. 3 is a view of a portion where the paper P is bound with the paper staple 101 as viewed from the back side, and three rows of bridge-shaped cuts C are shear-formed at the positions where the leg portions 103 and 104 overlap. The notch C is pressed into a concave shape, and the concave shape is maintained by the frictional resistance of the shear surface of the paper fiber. Therefore, unless the overlapped leg portions 103 and 104 are peeled off with a finger or the like, they do not easily return to a flat shape and have a sufficient holding force as simple binding.

  The paper staple 101 is joined by partial shearing with the tips of both legs 103 and 104 overlapped, and is not attached to the paper P. Therefore, when it is necessary to release the paper P once bound, the paper staple 101 is used. If the paper P is broken, the paper P can be easily unwound, and unlike the conventional configuration in which the adhesive tape is attached to the paper, there is no possibility of the paper P being torn or torn. In addition, when the paper P is discarded or applied to the shredder device, it is not particularly necessary to remove the paper staple 101. Of course, the paper staple 101 can also be coated with an adhesive. However, even the one not using an adhesive as shown in the figure has a necessary and sufficient binding performance and has no adhesive. By using the used paper staples, it is possible to further reduce the environmental load during the disposal process.

  In the above embodiment, the comb-shaped die 11 is fixed and the comb-shaped punch 41 is lifted. However, the comb-shaped punch 41 is fixed and the comb-shaped die 11 can move up and down a certain range. It is good also as a structure. That is, when the cutter blade 23 in FIG. 2-2 penetrates the paper and stops descending, the comb-tooth die 11 is unlocked, and when the cutter blade 23 is further pushed down from the state of FIG. By configuring the die 11 to be pushed toward the comb-shaped punch by being pushed by the cutter blade 23, the binding operation is performed in the same manner as described above, and the lowering of the cutter unit 21 is performed in the same manner as a general stapler. A configuration in which a single binding process is completed by an operation can be realized, and a binding device with good operability can be provided.

  FIG. 4 shows another embodiment of the binding mechanism. The cutter unit 21, the pair of rollers 31, 32, and the paper staple 101 are the same as those in the embodiment of FIG. A pair of left and right dies 51 are disposed directly under the cutter unit 21, and a pair of left and right punches 61 are disposed under the die 51. The pair of punches 61 has a shape in which the upper end of the round bar is cut obliquely, and is formed so as to punch out a semicircle instead of a full circle, and the right and left punches 61 are arranged 180 degrees opposite to each other. ing. The pair of left and right dies 51 are formed with circular punched holes 51a corresponding to the punches 61, and are horizontally moved from the initial position to the front and rear, respectively, as indicated by arrows by a slide mechanism (not shown).

  Next, the operation of the binding mechanism will be described. FIG. 5-1 shows an initial stage of the binding process, in which the paper staple 101 is set inside the cutter unit 21, and the paper staple 101 is held by the left and right cutter blades 23 and the paper P to be bound. Are set on a pair of dies.

  FIG. 5-2 shows a state where the cutter portion 21 is lowered and the cutter blade 23 penetrates the paper P, and the crown portion of the paper staple 101 is in pressure contact with the surface of the paper P and the die 51. Then, as shown in FIG. 5-3, the left and right rollers 31 and 32 enter the inside of the cutter blade 23 through the square holes 24 of the cutter blade 23, and bend the legs 103 and 104 of the paper staple 101 inward. The movement timing or standby position of the left and right rollers 31 and 32 is shifted, and the left leg 103 and the right leg 104 are bent in this order and folded so that the right leg 104 overlaps the surface of the left leg 103. This is the same as in the first embodiment.

  Next, as shown in FIG. 5-4, the pair of left and right punches 61 are raised, the overlapping leg portions 103 and 104 are pressed by the punch 61 and the die 51, and the overlapping portions of the leg portions 103 and 104 are sheared. A semi-circular punch hole is punched, and then the punch 61 descends as shown in FIG. 5-5, and the rollers 31 and 32 return to their initial positions. FIG. 6-1 shows a side cross-section of the punched state of FIG. 5-4, and FIG. 6-2 shows a side cross-section of the punch lowered state of FIG. 5-5.

  Subsequently, the pair of left and right dies 51 were horizontally moved backward and forward, respectively, and as shown in FIG. 6-3, the edge of the circular punched hole 51a of the die 51 was punched into the legs 103 and 104. Push the semicircular tab T, turn it upside down and bend it, and as shown in Fig. 6-4, the die 51 moves to the position where it completely comes out from the loop of the paper staple 101, and the bound paper P Is released.

  FIG. 7 is a view of the portion where the paper P is bound with the paper staple 101 as viewed from the back side, and two semicircular punch holes are punched 180 degrees opposite to each other where the leg portions 103 and 104 overlap. The punched and punched portion (semi-circular tab portion T) is folded between the leg portions 103 and 104 and the paper P, and the coupling of the leg portions 103 and 104 may be caused by an external force applied by a normal page opening / closing operation or the like. It does not come off and has a sufficient holding force as a binding means. Further, in the same manner as in the first embodiment, when it is necessary to release the paper P once bound, the paper P can be easily released by tearing the paper staple 101.

  The present invention is not limited to the above-described embodiment, and various modifications are possible within the technical scope of the present invention, and it is natural that the present invention extends to those modifications.
