DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for binding documents, bags, and the like, and more particularly to a binding device using a tape for punching a hole in a bundle of documents and the like and binding the documents with a tape through a tape made of paper, for example. And binding tapes.

[0002]

2. Description of the Related Art A conventional binding device uses a staple made of metal needles which is driven into a bundle of documents by a stapling type stapling machine, and the staples penetrate through the back surface of the document and protrude from the back surface of the document. The staples were folded inward to bind the documents.

In a stapling machine (stapling machine) using staples according to this method, when binding a document,
There is a risk that staples may be accidentally pierced into the hands, the staples may not be folded properly, may be stuck on clothing while standing, and scratches may be made on the skin. In addition, if the document is damaged or if it is no longer needed and the bound document is released, it is necessary to prepare a device such as a remover that removes staples.If there is no remover, you will need to forcibly lift the nail and remove it. However, there is a possibility that the nail may be damaged or the nail may be broken if the staple is thick.

Further, when an unnecessary document is applied to a document cutter such as a shredder, it is necessary to remove staples from the bound document. This means that if the paper stapler is stapled and erroneously applied to the paper cutter, the staples will be caught in the machine, causing trouble in operation and further damaging the blade of the cutter, thereby shortening the life of the machine. There was a problem that led to things. Also, stapling machines may be used to bind envelopes,
Using a letter opener was also a cause of trouble. Therefore, stapling the envelope has not been highly recommended given the inconvenience of opening.

On the other hand, when a document stapled with metal staples is stored as a bundle of documents, only the portion stapled becomes thicker. Therefore, when many documents are stacked and stapled, for example, the upper left portion is stapled. Only the intensively unusually thick paper, the overall width of the stored documents was unnecessarily thick. For documents that are stored for many years,
In fact, metal staples are not used. This is thought to be the result of the metal staples rusting relatively early, and the staples binding the documents often rusted and suffered post treatment. As described above, since metal staples cannot be used for documents that need to be preserved for many years, paper saws, binding strings, and the like have been used in actual places.

In the case of a staple in which a bag of food or the like is bound, the removed staple may be mixed in the food or the like, or a staple that is not intentionally removed may come off and the staple may be mixed in the food or the like. There was a risk of danger. Further, since the removed staples are sharp at both ends, there is a possibility that a risk of damaging a finger or the like may occur.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a binding device and a binding tape using a tape of a type that binds a document or the like with a tape made of paper or the like from which the conventional disadvantages have been eliminated. .

[0008]

In order to achieve the above-mentioned object, a tape binding device according to the present invention comprises a tape coated with an adhesive and a hole punching mechanism for punching a hole in a bound document by a blade. And a binding mechanism using a tape in which an end portion of a document to be bound and a hole formed therearound are wound once or half-wrapped with a tape and pressed and adhered by a document pressing body.

The binding tape used in the binding device is formed by cutting an adhesive tape into a predetermined length and attaching the tape to a peelable auxiliary tape.

[0010]

The binding device using a tape according to the present invention is of a type in which a document or the like is bound with a paper or plastic tape or the like. In the embodiment shown in FIG. And the adhesive on the back surface is held in such a manner as to face a document or the like which is progressing. The documents to be stapled are inserted into the movable holding body, and the moving holding body is inserted into the hole punching mechanism until it comes into contact with the wall. As a result, the leading end surface of the moved document is bonded to the adhesive on the back of the adhesive tape, and the leading end of the tape is bent and attached to the upper surface of the document or the like. At the same time, the back surface of the adhesive tape is attached to the leading edge of the aligned documents and the like, and is also bent and attached to the bottom of the documents and the like. With the document inserted, the push-down member of the punching mechanism is pushed down. Before the blade body of the punching mechanism reaches the document or the like, the document pressing body reaches and presses the upper surface side of the document or the like, whereby the front end portion of the back surface of the adhesive tape is firmly attached to the upper surface of the document or the like. At the same time, it is firmly adhered to the back side of the documents and the like, and at the same time, presses down the documents and the like which may vary.

Immediately thereafter, the blade body reaches the upper surface side of the document or the like, and penetrates and punches the document bundle by pressure from above. As a result, a tape through hole is formed in a document or the like.
The other end of the adhesive tape is inserted through the hole from the lower surface to the upper surface (or from the upper surface to the lower surface), and is attached to both upper and lower surfaces. Next, when the document or the like is extracted from the punching mechanism, the bound document or the like is pressed from above by a rotating pressing body. As a result, the other end of the adhesive tape that has passed through the hole and protrudes to the upper surface side is firmly fixed to the upper surface side of the document. In addition, the projection provided on the back of the movable holding member engages with the tape feed hole of the auxiliary tape, forcibly peels the next adhesive tape from the auxiliary tape, and partially rises upward. Waits for the next binding operation.

Inserted below. At this time, by sticking sticking tape 7 to-face p end face of the side p ₁ is held at the rising state described above for binding is anyway reached the positioning portion 20, attaching tape 7,
The part surface p side where the first half is bound and the mounting surface 2 of the positioning part 20
0a, between the abutting surface 20b and the U-shaped surface extending from the lower surface of the pressing piece 17b of the pressing body 17, the rear half is peeled off with the rear end adhered to the auxiliary tape 8, and the opening 24 is formed.
Is located in a bent shape from below. When the adhesive tape 7 is peeled from the auxiliary tape 8, the auxiliary tape 8 is pulled, but the tape feed hole 10 is
8, the adhesive tape 7 is latched and held, and the adhesive tape 7 is smoothly peeled off.

In this state, when the pressing member 15 is pressed down by the pressing handle 15b against the restoring elasticity of the first restoring spring member 19a, the pressing body 17 is moved to the front end side of the front half of the adhesive tape 7. The document P is pressed down via the pressing spring member 18 while being in contact with the sheet P, is pressed against the binding surface p of the document P, and the binding surface p is placed on the mounting surface 20 of the positioning unit 20.
a. As a result, the first half of the adhesive tape 7 is firmly attached from the upper surface side of the binding surface p to the end surface and the lower surface (see FIG. 10).

Further, when the pressing member 15 is pressed down, as described above, the pressing member 15 moves downward while contracting the second restoring spring member 19b, so that the blade 16 passes through the adhesive tape 7 through the hole. It works as a member. That is, the blade body 16 is lowered through the insertion opening 12b by the downward movement of the pressing member 15, and the blade edge 16a reaches the binding surface p of the document P, and the binding is performed by pressing down the pressing member 15 with the pressing pressure. Piercing the surface p, piercing a slit-shaped through hole h having the same size as the cross section of the blade body 16 and penetrating the surface p to be bound, and opening 24
From the lower side of the guide portion 13. At the site where the blade 16 is inserted, the rear half of the adhesive tape 7 is present with the rear end adhered to the auxiliary tape 8 as described above. The rear end portion of the blade body 16 is slid by the insertion operation so as to be separated from the auxiliary tape 8 and is fitted into the tape fitting hole 16b of the blade body 16 by a repulsive force (see FIG. 11). During the punching operation of the blade body 16, the pressing body 17 continues to press the binding surface p side of the document P by the contraction of the pressing spring member 18.

When the pressing of the pressing member 15 is released from this state, the pressing member 15 is slid upward strongly by the synergistic restoring elasticity of the first and second restoring spring members 19a and 19b. Together with the operation, the blade body 16 also rises rapidly, and is reliably removed from the through hole h formed in the binding surface p of the document P through the opening 24. At this time, the rear end of the adhesive tape 7 fitted into the tape fitting hole 16b of the blade body 16 passes through the through hole h of the part surface p to be bound as the blade body 16 rises, from the lower surface side to the upper surface side. (Figure 1
2). In the removal operation of the blade body 16, the rear end portion of the adhesive tape 7 is fitted into the tape guide groove 16 c between the blade tip 16 a of the blade body 16 and the tape fitting hole 16 b, and is within the thickness of the blade body 16. And the pressing body 17 is pressed down by the elasticity of the pressing spring member 18 to bind the surface p.
Side is kept pressed, so that the adhesive tape 7
The rear end portion is smoothly led out from a through hole h having the same size as the cross section of the blade body 16.

When the return slide of the pressing member 15 is completed, the pressing body 17 is raised and the pressing piece 17b is pressed.
Moves away from the binding surface p of the document P.

In this state, when the movable holding body 40 is pulled out from the lower side of the main mechanism accommodating section 12 and slides forward, the sliding surface p side of the binding portion of the document P is rotated by the rotary pressing body 22 and the pressing surface section 23. Pass between. During this passage, the binding surface p
The rear end of the adhesive tape 7 led out to the upper surface side is bent to the upper surface side of the binding portion surface p by the rotary pressing body 22 so that the adhesive tape 7 is substantially C-shaped with respect to the binding portion surface p. Affixed to
Together with the binding portion surface p, the rotary pressing body 22 pressed by the spring member 22c and the pressing portion 23 sandwich the pressing member 23,
The entire surface is firmly adhered to the binding portion surface p (see FIG. 13).

From this state, the movable holding body 40 is moved to the guide portion 1.
3, the document P bound by the adhesive tape 7 is removed. This document P is bound by the adhesive tape 7 in the state of the arrow a in FIG.

When the movable holding body 40 is pulled out and slid,
The feed claw 44 provided as a member for sending out the binding tape provided on the movable holding body 40 is engaged with the tape feed hole 10 of the binding tape 6 to move the auxiliary tape 8 from which the adhesive tape 7 has been peeled forward. Let it. When the movable holding body 40 is moved to the front end, as described above,
The guide piece 46 is pushed forward by the locking cam 47 and is automatically moved.
Will be sent for the length of the next unit. By feeding the binding tape 6, that is, shifting the auxiliary tape 8, the next adhesive tape 7 is peeled off from the auxiliary tape 8 and set up as a preparation stage for the next binding operation in the same manner as the preparatory operation described above. It is held in the state where it was.

By binding the document P or the like with the adhesive tape 7 in this manner, the auxiliary tape 8 is sequentially shifted forward and sent out from the front end face side of the tape guide 26. The supplied auxiliary tape 8 is inserted into the tape feed hole 1.
0 is cut and removed by engaging and pulling with a cutting projection 30 projecting from the front end surface of the tape guide 26.

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various shapes and configurations of each member can be changed without departing from the spirit of the present invention. Also, the binding method using the adhesive tape can be variously changed.

For example, the adhesive tape has a length obtained by adding twice the length from the end of the document to the hole and twice the thickness of the document to be bound, as described above. Although the length is set so as to encircle the gap between the end and the hole, the difference in the thickness of the documents to be bound can be solved by giving a margin to the length of the tape. In other words, for thin documents, the edges of the tape will overlap, and for relatively thick documents, the leading edge of the tape and the trailing edge of the tape will be adhered at a small interval without overlapping. become. Also,
In the above-described embodiment, the order of inserting and attaching the adhesive tape is as follows. First, one end of the tape is attached to the upper surface of the end of the document to be stapled, and the tape is bent at 90 degrees and then applied to the end of the document. Adhesive bonding, further bending by 90 degrees and affixing to the lower surface of the document, and then adhesively bonding to the end face of the document with the insertion hole through the tape insertion hole h drilled by the blade. When the document is pulled out, the tape is further bent by 90 degrees and the other end of the tape is attached to the upper surface of the document near the hole h. As a result, as shown by arrow a in FIG. 3, the adhesive tape 7 is folded into a bag shape and attached around the document P.
Has a substantially C-shape facing upward. However, the binding shape of the document P by the adhesive tape 7 does not need to be an upward C-shape, but may be a U-shape joint in the reverse direction as shown by the arrow finger c in FIG.

As a method of inserting the tape through the perforated hole, as in the above-described embodiment, after the blade body pierces the document, the tape is inserted into the center tape insertion hole, and when the blade body is pulled out, the tape together with the tape is pulled out. The structure shown in FIG. 1 in which the tape is pulled up and the hole is inserted into the hole, and the state in which the tape is previously inserted into the blade body formed in the tape insertion hole at the center before the start of the punching operation, and the tape remains inserted. It is conceivable to adopt a structure in which a tape is inserted into a document while punching the document with a blade. The method of inserting the tape into the insertion hole is not limited to this method.

In this embodiment, as shown in FIG. 8, the shape of the blade body 16 has an inverted mountain-shaped blade tip 16a curved in the center, but the shape of the blade body is not limited to this. Not something. When the bundle of documents is thick, the shape of the normal blade is desirably a single blade having a chevron-shaped tip toward the center of the tip. The number of blades is not limited to a single blade, but a plurality of blades can be used. Whether the shape of the cutting edge is a single blade or a double blade and the direction of the cutting edge can be freely selected. Also, considering that a machine such as a punch has a structure in which a round hole is formed at the corner of a document, this embodiment also employs a box-shaped or round-shaped perforation blade that forms a rectangular hole at the end of the document. An embodiment in which a small hole having a fixed width for allowing the tape to penetrate is also possible. In this case, there is a possibility that the operation of penetrating the tape through the hole becomes extremely easy. In this embodiment, the tape is forcibly lifted to the upper surface and penetrated by making work on the blade portion, but if a wide hole is formed, the tape can be easily inserted into the through hole. It is no longer necessary to force through the hole.

Further, in this embodiment, the blade body 16 pierces the document bundle from the top to the bottom of the document, but it is also possible to provide a hole through the document from the bottom to the top. In this embodiment, the tape is inserted into the center insertion hole of the blade after the hole is formed in the document. However, after the tape is passed through the tape insertion hole 16b in advance, the blade body 16 is brought into contact with the document. It can also be configured to make a hole.

Further, in the above-described configuration, only the first restoring spring member 19a may be used as the restoring elastic body that causes the push-down member 15 to return and slide, or the first and second restoring spring members 19a may be used. And 19b are combined, that is,
It is also possible to use a spring member that is integrally formed and has a large elasticity in the lower half.
