2. Description of the Related Art An automatic wrapping machine for binding a plurality of products
The machine has a binding tape (hereinafter referred to as a "bundling tape") that is wound around a product or the like (hereinafter referred to as a "bundled object") for binding. In addition, the automatic strapping machine is provided with a placing table for placing an object to be bound, and the object to be bound transported on the placing table is generally a simple operation (button operation, pedal operation). (Operation etc.), it is bound with a binding tape.

More specifically, first, a bundled object is placed on a placing table of an automatic strapping machine by using a conveying means such as a belt conveyor (conveying step, placing step), and then button operation and the like. The binding tape stored in the machine is wound around the outer periphery of the object to be bound (winding step), and the overlapping portion of the binding tape that has been wound and overlapped is heat-treated to form a binding tape. Bonded (heat bonding step). That is, the objects to be bound are bound by the binding tape through the carrying step, the placing step, the winding step, the thermal bonding step and the like.

As a binding tape used in the automatic strapping machine as described above, for example, Japanese Patent Laid-Open No. 2002-5
The tape disclosed in Japanese Patent No. 3166 (hereinafter referred to as "conventional tape") is known. This conventional tape is composed of three films bonded together (laminated), with heat-bondable films on the outer layers on both sides, and on the inner layers sandwiched between these films. A film having a plurality of fine through holes is arranged. That is, since the conventional tape has the three-layer structure as described above, the outer layer is adhered by heat treatment, and when the bound state is released, it is easily sheared by the fine through holes in the inner layer. can do. That is, the conventional tape realizes the thermal adhesiveness and the easy shearing due to the three-layer structure.

[0005]

However, the tape according to the prior art (conventional tape) has the following problems.

That is, since the conventional tape uses a plurality of films in order to realize thermal adhesiveness and easy shearing, there is a problem that the manufacturing process for laminating is complicated. Specifically, the manufacturing process is complicated because a step of forming a plurality of fine through holes in the inner layer and a step of laminating and adhering three films are required. In addition, multiple materials (films) are required,
Since the manufacturing process becomes complicated, there is a problem that cost increase cannot be denied. Furthermore, since conventional tapes are composed of multiple materials (that is, they are not composed of a single material), there may be difficulties during recycling after use (after shearing). .

Therefore, the present invention has been made in order to solve the above-mentioned problems of the prior art, and provides a binding tape which can realize thermal adhesion and easy shearing by using a single-layer strip-shaped film. The task is to do. Another object is to provide a method for manufacturing such a binding tape.

It is formed by using a resin film, and is characterized in that a plurality of push cut scratches are provided along the side portion of the strip film.

According to this structure, the band-shaped film is formed by using the synthetic resin film having a heat-adhesive property, and a plurality of push-cut scratches are provided along the side edges of the band-shaped film. A binding tape having heat adhesiveness and easy shearing property can be obtained. Here, the "push cut scratch" is a scratch or the like obtained by pressing a cutting portion such as a cutter against the side portion of the strip film. The depth of the push cut wound is preferably set within a range of, for example, about 0.001 mm to 5 mm depending on the rigidity of the strip film and the like. Also, the depth of this press cut is
More preferably, it is set to about 0.001 mm to 2 mm. A push-cut wound having such a depth is difficult to recognize with the naked eye, but can be easily sheared by hand.
Further, according to such a configuration, since the binding tape is configured by using the single-layer strip-shaped film, it is possible to perform the recycling or the like without separating the constituent elements.
Furthermore, in the present invention, since a plurality of scratches (push cuts) are formed by pressing a cutting part such as a cutter, almost no cutting chips are generated, and dust is not generated against the objects to be bound during binding. It is possible to provide a binding tape capable of suppressing the adhesion of the like.

It is characterized in that a plurality of push-cut scratches are provided along the side edges of the strip-shaped film by pressing the push-cut tool against the exposed surface of the side edges of the wound strip-shaped film.

According to this structure, in addition to the various effects described above, a new effect that the binding tape can be formed more easily can be obtained. That is, if the press-cutting tool is pressed against the side surface exposing surface of the band-shaped film wound in a roll, the band-shaped film having a plurality of press-cutting scratches along the side part, which is a feature of the present invention. Can be easily obtained. That is, in the case of a conventional tape, since it is necessary to form a plurality of through holes, the film wound in a roll shape is once drawn out, and after the through holes are formed in the film in the drawn state, the tape is again formed. It must be wound into a roll. However, according to the present invention, as described above, since the roll-shaped film can be processed without being pulled out, the binding tape can be obtained more easily than in the past.

Further, the present invention for solving the above-mentioned problems is a method for producing a binding tape which has a predetermined tensile strength and can be easily sheared, and is a strip-shaped film wound in a roll shape. It is characterized in that it has a push-cutting step of pushing the push-cutting tool against the exposed surface of the side portion.

Further, in the method for manufacturing a binding tape according to the present invention, it is preferable that a tool having a plurality of cutting portions arranged substantially in parallel is used as the pressing tool.

According to this preferred structure, it is possible to provide a plurality of push-cutting scratches on the strip-shaped film wound in a roll shape by merely pressing the push-cutting tool once. A binding tape having the effect of can be obtained. Further, it is possible to obtain a binding tape having a plurality of pressing cuts with almost no generation of chips or the like.

Further, in the method for producing a binding tape according to the present invention, in the pressing step, the pressing tool is pressed a plurality of times against the side surface exposed surface of the band-shaped film wound in a roll shape. The configuration is preferable.

According to this preferred structure, more pressing cuts are formed on the side edges of the strip film by a simple operation (pressing multiple times) using a tool having a simple structure (pressing tool). be able to. Therefore, it is possible to easily obtain a binding tape that can be sheared from many places.

FIG. 1 is a schematic perspective view of a binding tape according to an embodiment of the present invention. More specifically, it is a schematic perspective view of a binding tape wound in a roll shape.

The binding tape 1 according to the present embodiment is constructed by using a single-layer strip-shaped film, and as the strip-shaped film, for example, a synthetic resin film (for example, a non-stretched film, a uniaxial film) having thermal adhesiveness Stretched film,
A biaxially stretched film or the like) is used. Further, as a material for forming these films, polypropylene or a foam member (foam synthetic resin) such as polypropylene foam is used.

Further, the strip-shaped film is formed of, for example, a material having a heat fusion property so as to have an appropriate heat adhesion property. If necessary, an adhesive or the like that exerts an adhesive effect by applying heat treatment is applied to the surface of the strip film. As a material having a heat-sealing property that forms a band-shaped film, its softening temperature is 100 ° C to 200 ° C.
The softening temperature is preferably about 110 ° C to 130 ° C. If the film is softened in such a temperature range, it is possible to appropriately perform heat bonding.

Further, in order to have a predetermined tensile strength, it is preferable to use, for example, a material having a tensile elastic modulus of about 1.0 GPa to 4.0 GPa as a material for forming the strip film. If a material having such a tensile elastic modulus is used, it has a predetermined tensile strength in the longitudinal direction of the binding tape, so that the objects to be bound can be bound appropriately.

The binding tape 1 according to this embodiment is shown in FIG.
As shown in (1), it is wound around the tube portion 2 formed of paper, plastic, or the like, and is installed in an automatic strapping machine or the like in such a rolled state. In this way, the strip-shaped film wound into a roll is referred to as a roll body 10.

The binding tape 1 according to the present embodiment is provided with a plurality of small pressing cuts 1K on the side portion 1A thereof, and the pressing cuts 1K are strip-shaped film rolls 10.
Is formed in the above state (details will be described later). That is, in the present embodiment, like a conventional tape, a film wound in a roll shape is once drawn, a through hole is formed in the film in the drawn state, and then the film is wound again in a roll shape. Without performing the complicated processing of
It is possible to easily obtain the binding tape 1 having a plurality of small press cuts 1K on the side portion 1A thereof.

Specifically, in the present embodiment, in order to form a push-cut flaw, a push-cut tool constituted by using a plurality of cutting parts such as cutters is used. Further, for example, this press cutting tool is integrally configured by disposing a plurality of cutting portions substantially in parallel.

Therefore, the pressing tool constructed as described above is pressed once against the side surface exposing surface 10A of the strip film (roll body 10) wound around the tube portion 2 (so-called pressing By performing the process once), in this embodiment, the side surface 10A is exposed.
Then, a press cut 10K1 (or a press cut 10K2) as shown in FIG. 1 is formed.

Next, in the present embodiment, as described above, a plurality of press cuts 10K1 are formed in parallel in one direction.
After (or the pressing cut 10K2) is formed, either the pressing tool or the roll body 10 is rotated. That is, the push-cut tool should have a predetermined angle with respect to the previously-formed push-cut flaw 10K1 (or the push-cut flaw 10K2).
The roll body 10 and the push-cut tool are relatively arranged, the push-cut process is performed again, and the push-cut flaw 10K2 is formed on the side edge surface 10A.
(Or a press cut 10K1) is formed.

In the present embodiment, by the two pressing steps, as shown in FIG. 1, pressing cuts 10K1 and 10K2 intersecting with each other are formed on the side surface 10A. Here, these press cuts 10K1, 10K2
However, it is shown in the case of being formed with an inclination of approximately 90 °.

Through the above steps, in the present embodiment, as shown in FIG. 1, the press cut scratches 10K1 and 10K2 are formed on the side surface exposed surface 10A of the roll body 10. The strip-shaped film forming the roll body 10 forms a binding tape having a plurality of press cuts 1K on the side portion 1A thereof.

The pressing cut 1K is preferably formed to a depth of, for example, about 0.001 mm to 5 mm according to the rigidity of the strip-shaped film, and from the viewpoint of appearance and slipperiness, 0.001 mm to It is more preferable that the thickness is about 2 mm. Thus a more preferred depth (0.0
If it is formed to be about 01 mm to 2 mm), the press cut 1K is difficult to discriminate with the naked eye, and even in the automatic strapping machine, it can be smoothly moved to perform proper bundling.

Further, even with the shallow push-cut flaws 1K as described above, the binding tape 1 according to the present embodiment is provided with a large number of push-cut flaws 1K on the side portions by the steps described above. In the case of shearing after binding (when releasing the bound state of the objects to be bound), it is possible to give the user an image that can be sheared from any location. Further, in reality, the pitch of each push cut 1K can be formed at a very narrow interval, so that no matter where the shearing is started, it is closest to the shearing start portion (or the largest force is applied). A shearing force acts on the push-cut wound 1K (in the acting direction), and it can be easily sheared from any place.

The interval (pitch) between the push cuts 1K is
It can be arbitrarily set by changing the installation interval of the cutting parts constituting the press cutting tool, the pressing position (or pressing angle) during the pressing process, and the like. Therefore,
According to this embodiment, it is possible to easily obtain the binding tape that can provide the easiness of shearing depending on the place of use.

The predetermined portion (adhesion portion) 1M is subjected to heat treatment, and the binding tape 1 is fixed and bound. In addition, this heat treatment,
Usually, it is performed by an automatic wrapping machine.

Further, since the binding tape 1 has a predetermined tensile strength (described above), when the binding tape 1 is bound in the manner as shown in FIG. Exhibits high strength against. Therefore, it is possible to maintain an effective bundling state in which there is no collapse of the roll or collapse of the load after bundling. Further, as described above, since the side edge portion 1A of the binding tape 1 is provided with the plurality of press cuts 1K, 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 needed.
That is, according to the present embodiment, it is possible to obtain the binding tape 1 that has high strength during binding and can easily release the bound state.

Further, according to the present embodiment, the banding tape 1 can be formed by using the single-layer strip-shaped film only in the press-cutting step without rewinding the film. Also, the manufacturing process and the manufacturing equipment can be greatly simplified. Further, as a result of these simplifications, a large cost reduction can be implemented.
