Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing paper band for packing an object to be packed by being wrapped around the band, and more particularly to a packing paper band suitable for use as a packing band of a packing machine or the like.

[0002]

2. Description of the Related Art In general, a band (packing band) used for so-called banding packing, which is a package that is formed by joining terminals of a band wrapped around an object to be packed, is used.
A resin band such as a polypropylene band called a P band is often used. However, recent environmental issues,
Speaking of problems such as waste disposal and the like, it is inevitable that this resin band is inferior in terms of disposal, recycling, and the like.

[0003] At present, a paper band (paper band), which can easily establish a recycling route as used paper, has attracted attention as a band for packing with a band instead of a resin band.

[0004]

Here, as a paper band used for a packing machine or the like, that is, a paper band for packing,
For example, it is generally known that a plurality of paper strings arranged side by side are integrally bonded with an adhesive or the like. However, the paper band formed by the bonding of the paper string is
Because the manufacturing process is complicated and the number of processes is relatively large, a reduction in production efficiency is unavoidable, and it is excellent in compatibility with environmental protection, etc., but it cannot be denied that the manufacturing cost is high. .

[0005] Therefore, for example, a band-shaped paper core material folded to a predetermined width is wrapped with an exterior paper material such as kraft paper, and these are integrally bonded under pressure bonding with application of an adhesive, or , Kraft paper and other paper materials are folded in multiple layers to form a band of a predetermined width, and these are bonded together under pressure bonding with the application of an adhesive, etc., which simplifies the manufacturing process. It is offered as a paper band.

[0006] However, these paper bands whose production process is simplified are simply obtained by simply laminating and bonding paper materials, so that they are compared with the conventional packing paper band formed by bonding paper strings. Thus, a decrease in the tensile strength cannot be avoided.

[0007] The present invention, in addition to simplifying the manufacturing process,
The purpose of the present invention is to provide a packing paper band structure for improving the tensile strength.

[0008]

According to the present invention, there is provided a paper core formed in a belt shape having a predetermined width along at least one longitudinal end of the paper core material. The reinforcing thread material is arranged. Then, these are integrally packaged with a predetermined exterior paper material, and are integrally formed as a paper band under the entire pressure bonding accompanied by application of an adhesive to at least the inner surface of the exterior paper material.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings.

As shown in FIGS. 1A and 1B, in a packing paper band structure 10 according to the present invention, a paper band 12 includes a paper core material 14, a reinforcing thread material 16, It is formed as a combination with the material 18.

As can be seen from FIG. 1 (A), the paper core material 1
4 is formed, for example, as a laminated body in which a plurality of band-shaped single members 20 cut into a band shape having a predetermined width by a slitter or the like are integrally stacked, and along a longitudinal end of the paper core material, for example, along both sides. A predetermined reinforcing thread material 16 made of cotton thread or the like.
Is arranged. Then, these are provided with the specified exterior paper material.
18, for example, integrally wrapping with kraft paper and applying an adhesive to at least the inner surface of the exterior paper material, for example, by applying pressure bonding of the whole with the application of a water-soluble glue of PVA vinyl acetate, and And the paper band 12
It is formed so as to have a sectional form shown in FIG.

In the paper band 12 having such a cross-sectional configuration, the reinforcing thread 16 arranged along the longitudinal side surface of the paper core 14 functions as a reinforcing material in the longitudinal direction. As compared with the configuration combining paper materials, the tensile strength is reliably increased.

Further, in the present invention, the reinforcing thread 16 is arranged along the longitudinal side end of the paper core 14, and these are integrally wrapped by the exterior paper 18 to be adhered by an adhesive. Since it suffices to form an integrated structure, the manufacturing process can be simplified and the number of working steps can be reduced.

As described above, in the packing paper band structure 10 of the present invention, the tension of the paper band 12 is enhanced by the reinforcement by the reinforcing thread material 16 in spite of the configuration enabling the manufacturing process to be simplified. Since the strength is reliably increased, it is possible to easily and appropriately secure the improvement of the tensile strength in addition to the simplification of the manufacturing process of the paper band.

By using a water-soluble glue which is easily dissolved as an adhesive applied to the inner surface of the exterior paper 18, the paper core 14 of the paper band 12 and the paper of the exterior paper 18 can be used. This facilitates separation of the reinforcing thread material 16 and the adhesive, so that the paper band can be reused,
And it can respond appropriately to reproduction. Therefore, according to the present invention, it is possible to easily provide the paper band 12 having excellent recyclability without increasing the number of manufacturing steps and decreasing the tensile strength.

Further, the paper band 12 includes a paper core 14 made of paper, an exterior paper 18 and a reinforcing thread 16 made of cotton yarn or the like.
Because of this combination, the disposal and incineration can be easily performed. In other words, also in this regard, this paper band 12
Can contribute to environmental protection.

In this embodiment, the adhesive applied to the inner surface of the exterior paper 18 is embodied as a water-soluble glue. However, the paper core 14, the reinforcing thread 16 and the exterior paper Since it is sufficient to form 18 integrally under the adhesive,
The adhesive is not limited to the water-soluble paste, and another adhesive may be used. However, if the adhesive applied to the inner surface of the exterior paper material 18 is made water-soluble, the material can be easily reused and dissolved by processing at the time of reproduction, and there is no adverse effect on each material. The recycling performance of the paper band 12 is further improved.

Incidentally, it is desirable to apply a thermoplastic resin adhesive to the surface of the paper band 12 in advance. If the surface of the paper band 12 is coated with a thermoplastic resin adhesive as described above, the bonding between the ends of the paper band by heating and pressing the surface of the paper band can be obtained. , Especially an automatic packing machine.

Here, in the embodiment of the present invention, the paper core material 14 is embodied as a stack of the band-shaped single materials 20. However, a structure having a predetermined thickness is sufficient. However, the present invention is not limited to this. For example, a material obtained by folding a paper material into a bellows shape having a predetermined width may be used as a paper core material. However, the single band material 20 shown in this embodiment can be easily cut by a slitter or the like, and can be easily stacked. Therefore, as in this embodiment, a laminated body obtained by stacking the single band material is used. If the paper core 14 is formed as described above, the manufacturing process can be further simplified.

In the embodiment of the present invention,
On both sides of the longitudinal end of the paper core material 14, the reinforcing thread material 16 is arranged.If the paper core material and the reinforcing thread material are integrally wrapped and adhered by the exterior paper material 18, Because it is sufficient, it is not limited to this. For example, only one longitudinal end of the paper core material is
It is good also as composition which arranges a thread material for reinforcement. However, if the reinforcing thread 16 is arranged on both sides of the longitudinal end of the paper core 14 as in this embodiment, uniform reinforcement of the paper band 12 can be easily achieved. Improvements in tensile strength are made possible by this configuration.

The embodiments described above are intended to explain the present invention, and do not limit the present invention in any way, and all modifications and alterations within the technical scope of the present invention are also included in the present invention. It goes without saying that it is included in the invention.

[0022]

As described above, according to the packing paper band structure of the present invention, the tensile strength of the paper band is reliably increased by the reinforcement with the reinforcing thread material, so that the manufacturing process of the paper band is simplified. It is possible to easily and appropriately secure the improvement of the tensile strength in addition to the modification.

Then, under the dissolution of the adhesive, the paper band is easily separated into the paper core material, the paper material of the exterior paper material, the reinforcing thread material, and the adhesive. It becomes possible to respond appropriately to use and reproduction. Therefore, according to the present invention, it is possible to easily provide a paper band having excellent recyclability without increasing the number of manufacturing steps and reducing the tensile strength.

Further, according to the paper band having the packing paper band structure of the present invention, the paper band can be easily discarded and incinerated, which can also contribute to environmental protection and the like.

By applying a thermoplastic resin adhesive to the surface of the paper band, bonding between the ends of the paper band by heating and pressing the surface of the paper band can be obtained.
The present invention can be easily applied to a packing machine, particularly an automatic packing machine or the like, which uses the bonding by heating and pressure bonding as its connecting means.

If the adhesive applied to the inner surface of the exterior paper material is made water-soluble, the material can be easily reused and dissolved by processing at the time of reproduction, and there is no adverse effect on each material. The recycling performance of the paper band is reliably improved.

Since it is easy to cut the band-shaped single material itself and it is easy to stack it into a paper core material, the paper core material is formed as a laminate formed by stacking the band-shaped single material. This further simplifies the manufacturing process.

Further, if reinforcing yarns are arranged on both sides of the longitudinal end of the paper core, the reinforcement in the paper band can be made homogeneous, so that the tensile strength of the paper band is further improved by this configuration. It becomes possible.
