BACKGROUND OF THE INVENTION
The present invention relates to a method for manufacturing a binding tape that is used to wrap and bind individual or a plurality of commodities, or to easily bind printed materials or the like using an automatic strapping machine.
[0002]
[Prior art]
An automatic strapping machine for bundling a plurality of products is a bundling tape (hereinafter referred to as a “bundling tape”) that is wound around a product or the like (hereinafter “bundled object”) in order to perform bundling or the like. In the cabin. In addition, the automatic strapping machine is provided with a mounting table for mounting the object to be bound, and the object to be bound which has been transported on the mounting table is generally operated by simple operation (button operation, pedal). The tape is bound with a binding tape by an operation or the like.
[0003]
More specifically, first, the object to be bound is placed on the placing table of the automatic strapping machine using a conveying means such as a belt conveyor (conveying process, placing process), and then the inside of the machine is operated by a button operation or the like. The binding tape accommodated in the tape is wound around the outer peripheral portion of the object to be bound (winding step), and the overlapping portion of the binding tape that is wound and overlapped is subjected to heat treatment to bond the binding tape. (Thermal bonding process). That is, the objects to be bound are bound by the binding tape through the transporting process, the placing process, the winding process, the thermal bonding process, and the like.
[0004]
As described above, as a binding tape used in an automatic strapping machine, for example, a tape disclosed in JP-A-2002-53166 (hereinafter referred to as “conventional tape”) is known. . This conventional tape is constructed by adhering three films (constructed by laminating), and a film having heat-fusibility is arranged on both outer layers, and an inner layer sandwiched between these films is arranged. A film having a plurality of fine through holes is arranged.
That is, this conventional tape has a three-layer structure as described above, so that when the outer layer is bonded by heat treatment and the bundled state is released, it is easily sheared by a plurality of fine through-holes in the inner layer. can do. That is, the conventional tape achieves thermal adhesiveness and easy shearing by such a three-layer structure.
[0005]
[Problems to be solved by the invention]
However, the tape according to the above prior art (conventional tape) has the following problems.
[0006]
That is, the conventional tape uses a plurality of films in order to realize thermal adhesion and ease of shearing, and thus has a problem that the manufacturing process for lamination is complicated. Specifically, since a process of forming a plurality of fine through holes in the inner layer and a process of laminating and bonding three films are required, the manufacturing process is complicated. In addition, since a plurality of materials (films) are required and the manufacturing process becomes complicated, there has been a problem that cost increases cannot be denied. Furthermore, since conventional tapes are composed of a plurality of materials (that is, they are not composed of a single material), there may be difficulties in recycling after use (after being sheared). .
[0007]
Accordingly, the present invention has been made to solve the above-described problems of the prior art, and provides a binding tape that can achieve thermal adhesion and ease of shearing using a single-layer belt-like film. Let it be an issue. Another object of the present invention is to provide a method for producing such a binding tape.
[0008]

Having a pressing process for forming a plurality of parallel cutting flaws in one direction by pressing a cutting tool configured by arranging a plurality of cutting parts in one direction with an arbitrary installation interval with respect to the part surface. It is a feature.
[0009]
According to such a manufacturing method, since a plurality of press cuts are provided along the side edges of the belt-like film, a binding tape having easy shearing can be manufactured, and the binding tape can be formed more easily.
[0010]
Here, the “push cut” refers to a flaw obtained by pressing a cutting portion such as a cutter against the side portion of the belt-like film. And it is preferable to set the depth of this press cut within the range of about 0.001 mm-5 mm according to the rigidity of a strip | belt-shaped film, etc., for example. Moreover, it is more preferable that the depth of the press cut is set to about 0.001 mm to 2 mm.
[0011]
If it is such a depth of cut, it is difficult to recognize with the naked eye, but it can be easily sheared by hand. Furthermore, in the present invention, since a plurality of scratches (cutting flaws) are formed by pressing a cutting part such as a cutter, almost no chips or the like are generated, and dust is bound to the objects to be bound at the time of binding. It can be set as a binding tape which can suppress adhesion | attachment etc.
[0012]
Moreover, if the said cutting tool is pressed with respect to the side surface exposed surface of the said strip | belt-shaped film wound by roll shape, the strip | belt-shaped film which has a some cut along the side part which is the characteristics of this invention Can be easily obtained. In other words, in the case of a conventional tape, it is necessary to form a plurality of through-holes. Therefore, after the film wound in a roll shape is pulled out once and the through-holes are formed in the drawn film, It must be wound into a roll. However, according to the present invention, as described above, since it can be processed without pulling out a roll-shaped film, a binding tape can be obtained more easily than before.
[0013]
In the present invention , the band-like film wound in the roll shape and the pressing tool are relatively rotated so that the pressing tool has a predetermined angle with respect to the previously formed cutting wound. And a pressing step of pressing a pressing tool against the side surface exposed surface.
[0014]
According to such a manufacturing method, in addition to the various effects described above, crossed cuts are formed, and the band-like film becomes a binding tape having a plurality of cuts on the side.
[0015]
Furthermore, the present invention for solving the above-mentioned problems is characterized in that the pressing tool is pressed a plurality of times against the side surface exposed surface of the belt-like film . According to this preferable configuration, more pressing cuts can be formed on the side portion of the belt-like film by a simple operation (multiple pressing) using a simple configuration tool (pressing tool). . Therefore, a binding tape that can be easily sheared from many places can be obtained.
[0016]
Moreover, in the manufacturing method of the binding tape concerning this invention, it is preferable that the tool comprised by arrange | positioning the some cutting part substantially parallel as said pressing tool.
[0017]
According to this preferable configuration, it is possible to provide a plurality of pressing flaws on the strip-shaped film wound in a roll shape by pressing the pressing tool once. A binding tape having the same can be obtained. In addition, a binding tape having a plurality of press cuts can be obtained with little generation of chips and the like.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view of a binding tape according to an embodiment of the present invention. More specifically, a schematic perspective view of a binding tape wound in a roll shape is shown.
[0019]
The binding tape 1 according to the present embodiment is configured using a single-layer belt-like film. Examples of the belt-like film include a synthetic resin film having thermal adhesiveness (for example, an unstretched film, a uniaxially stretched film, Biaxially stretched film or the like) is used. In addition, as a material for forming these films, a foamed member (foamed synthetic resin) such as polypropylene or a polypropylene foam is used.
[0020]
Moreover, in order to have appropriate thermal adhesiveness, this strip | belt-shaped film is formed with the material which has heat-fusion property, for example. Moreover, the adhesive etc. which exhibit an adhesive effect by performing heat processing are apply | coated to the strip | belt-shaped film surface as needed. The material having the heat-fusibility that forms the belt-like film preferably has a softening temperature of about 100 ° C. to 200 ° C., more preferably a softening temperature of about 110 ° C. to 130 ° C. If it is a film softened in such a temperature range, it becomes possible to perform heat bonding appropriately.
[0021]
Further, in order to have a predetermined tensile strength, for example, a material having a tensile elastic modulus of about 1.0 GPa to 4.0 GPa is preferably used as a material for forming the belt-like film. If a material having such a tensile elastic modulus is used, it has a predetermined tensile strength with respect to the longitudinal direction of the binding tape, and the objects to be bound can be appropriately bound.
[0022]
As shown in FIG. 1, the binding tape 1 according to the present embodiment is wound around a tube portion 2 formed of paper or plastic or the like. It is installed in a strap machine. Thus, what wound the strip | belt-shaped film in roll shape is hereafter called the roll body 10. FIG.
[0023]
The binding tape 1 according to this embodiment is provided with a plurality of small cuts 1K on the side portion 1A, and the cuts 1K are formed when the belt-like film is in the state of the roll body 10 (details). Will be described later).
That is, in this embodiment, like a conventional tape, a film wound in a roll shape is once drawn, a through hole is formed in the drawn film, and then wound in a roll shape again. The bundling tape 1 having a plurality of small cuts 1K on the side portion 1A can be easily obtained without performing this complicated process.
[0024]
Specifically, in this embodiment, in order to form a press cut, a press cutting tool configured using a plurality of cutting parts such as cutters is used. In addition, for example, this press-cutting tool is configured integrally by arranging a plurality of cutting portions substantially in parallel.
[0025]
Therefore, the pressing tool configured as described above is pressed once against the side surface exposed surface 10A of the strip-shaped film (roll body 10) wound around the pipe portion 2 (a so-called pressing process is once performed). In this embodiment, the cut 10K1 (or the cut 10K2) as shown in FIG. 1 is formed on the side surface 10A.
[0026]
Next, in the present embodiment, after the press cut 10K1 (or the press cut 10K2) formed in parallel in one direction is formed as described above, either the press tool or the roll body 10 is used. Rotate. That is, the roll body 10 and the pressing tool are relatively arranged so that the pressing tool has a predetermined angle with respect to the previously formed pressing cut 10K1 (or the pressing cut 10K2), and the pressing process is performed again. A press cut 10K2 (or press cut 10K1) is formed on the side surface exposed surface 10A.
[0027]
In the present embodiment, as a result of the two pressing processes, as shown in FIG. 1, the pressing cuts 10K1 and 10K2 intersecting each other are formed on the side surface exposed surface 10A. Here, the case where these press cuts 10K1 and 10K2 are formed with an inclination of approximately 90 ° is shown.
[0028]
Through the steps as described above, in this embodiment, as shown in FIG. 1, press cuts 10 </ b> K <b> 1 and 10 </ b> K <b> 2 are formed on the side surface exposed surface 10 </ b> A of the roll body 10. Will form a binding tape having a plurality of cuts 1K on the side 1A.
[0029]
The press cut 1K is preferably configured to have a depth of about 0.001 mm to 5 mm, for example, depending on the rigidity of the belt-like film, and is about 0.001 mm to 2 mm in view of appearance and slipperiness. More preferably, it is configured. If it is formed in such a preferable depth (about 0.001 mm to 2 mm), this cut and cut 1K is difficult to distinguish with the naked eye, and also moves smoothly in the automatic strapping machine, and the like. Bonding can be performed.
[0030]
Moreover, even if it is the above shallow cut 1K, since the binding tape 1 concerning this embodiment is provided with many cuts 1K in the side part by the process mentioned above, after bundling In the case of shearing (when releasing the binding state of the object to be bound), an image that can be sheared from any location can be given to the user.
Furthermore, since the pitch of each press cut 1K can be formed at very narrow intervals, no matter where the shearing is started, it is closest to the shearing start portion (or has the largest force). A shearing force acts on the press cut 1K (in the direction in which it acts), and it is possible to easily shear from any location.
[0031]
Further, the interval (pitch) between the pressing cuts 1K can be arbitrarily set by changing the installation interval of the cutting parts constituting the pressing tool or the pressing position (or pressing angle) during the pressing process. Therefore, according to this embodiment, the binding tape which can provide the ease of shearing according to a use location can be obtained easily.
[0032]
FIG. 2 is a schematic perspective view showing a state in which a binding object such as a printed matter is bound using the binding tape according to the present embodiment.
In addition, in this embodiment, although the bundling method of the to-be-bundled object B using the bundling tape 1, the usage method of an automatic strapping machine, etc. are not demonstrated in particular, these methods are fundamentally the same as the past. Therefore, the binding tape 1 according to the present embodiment can be attached to the automatic strapping machine in the state of the roll body 10, and the same processes (conveying process, placing process, winding process, and thermal bonding process) as in the past. Etc.), the objects to be bound B can be appropriately bound. That is, FIG. 2 shows a state after the objects to be bound B are bound using the automatic strapping machine and the roll body 10.
[0033]
Moreover, the binding tape 1 according to the present embodiment has thermal adhesiveness as described above. Therefore, as shown in FIG. 2, when the object to be bound B is bound, the outside of the object to be bound B is wound around the predetermined portion (adhesion point) 1M of the binding tape 1 which is overlapped, and then the binding is performed. The tape 1 is fixed and bound. In addition, this heat processing is normally performed with an automatic strapping machine.
[0034]
Further, since the binding tape 1 has a predetermined tensile strength (described above), when the binding is performed in a manner as shown in FIG. Exhibits high strength. Therefore, it is possible to maintain an effective bundling state without the collapse of the roll after bundling, collapse of the load, and the like.
As described above, the side tape 1A of the binding tape 1 is provided with a plurality of press cuts 1K. Therefore, when a force acts in the width direction Y of the binding tape 1, the binding tape 1 Is easily broken. Therefore, the bound state can be easily released as necessary.
That is, according to the present embodiment, it is possible to obtain the binding tape 1 that has high strength at the time of binding and can easily release the binding state.
[0035]
Moreover, according to this embodiment, since it is possible to form the binding tape 1 only by a pressing process without rewinding the film using a single-layer belt-like film, the manufacturing process and Manufacturing equipment can be greatly simplified. Furthermore, with these simplifications, a large cost reduction can be implemented.
[0036]
Furthermore, according to this embodiment, since the binding tape 1 is configured using a single-layer belt-like film, recycling or the like can be performed without performing separation of the components.
[0037]
The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention.
[0038]
For example, in the present embodiment, the case where each of the press cuts 10K1 and 10K2 is formed with an inclination of approximately 90 ° has been described. However, the present invention is not limited to this configuration, Each push cut may be provided to have an angle of.
[0039]
Further, in the present embodiment, the case where the cut scar is formed on the side surface exposed surface of the belt-like film by the two cutting processes is described, but the present invention is not limited to this configuration, and three or more cutting processes By performing the above, more pressing cuts may be formed.
Furthermore, in this embodiment, although the case where the cutting tool comprised integrally by arrange | positioning a some cutting part substantially parallel (one direction) was demonstrated, this invention is not limited to this structure. Therefore, for example, a cutting tool may be configured by arranging a plurality of cutting portions in an intersecting state (two directions), and further, the pressing tool may be configured to have intersecting portions in three or more directions. Good. And when using the press-cutting tool which has such a structure, you may form a press cut on the side part exposed surface of a strip | belt-shaped film by a single press-cutting process.
