Description

本発明は、ロール状巻物に関し、詳しくは、所定長さの樹脂フィルムを紙製の管体（紙管）に巻き付けたロール状巻物であって、特に、紙管に業務用ストレッチフィルムを巻き取ったロール状巻物に好適な構造に関する。 The present invention relates to a roll-shaped scroll, and more specifically, is a roll-shaped roll in which a resin film having a predetermined length is wound around a paper tube (paper tube). In particular, a roll film for business use is wound around a paper tube. The present invention relates to a structure suitable for a rolled roll.

ポリ塩化ビニル、ポリプロピレン、ポリエチレン、ポリ塩化ビニリデン等の熱可塑性樹脂からなる単層又は多層の食品包装用ストレッチフィルムが広く知られており、この内、業務用ストレッチフィルムは、通常、内径約７５ｍｍ（３インチ）、外径８５〜９０ｍｍ、長さ３００〜５００ｍｍの紙管を巻芯として巻回されて使用されている。 Single-layer or multi-layer food packaging stretch films made of thermoplastic resins such as polyvinyl chloride, polypropylene, polyethylene, and polyvinylidene chloride are widely known. Of these, stretch films for business use generally have an inner diameter of about 75 mm ( 3 inches), a paper tube having an outer diameter of 85 to 90 mm and a length of 300 to 500 mm is used as a winding core.

巻芯として使用される紙管は、最内層から数枚のライナー紙、原紙、ライナー紙等を積層した所定の厚み・幅を有する軸芯用原紙を所定の角度で螺旋状に連続して層状に巻き重ね、酢酸ビニル系の接着剤で軸芯用原紙同士を接着して円筒状巻芯に形成し、その巻芯の外周面全体に所定の上質紙あるいは表面紙等を螺旋状その他各種形態で貼り付けた構成としてある。 The paper tube used as the winding core is a continuous layer of axial core base paper having a predetermined thickness and width in which several liner papers, base papers, liner papers, etc. are laminated from the innermost layer in a spiral at a predetermined angle. Are wound around each other and bonded to each other with a vinyl acetate adhesive to form a cylindrical core, and a predetermined quality paper or surface paper is spirally or other forms on the entire outer peripheral surface of the core. It is the structure pasted in.

このような紙管に前記ストレッチフィルムのような樹脂フィルムを巻付けたロール状巻物は、一般に、まず、前述のような熱可塑性樹脂に可塑剤等の加工助剤を添加した樹脂組成物を押出機に投入し、溶融状態で口金からフィルム状に押し出し、樹脂の熱変形温度以下に冷却してから所定の厚みまで延伸することによって所定の樹脂フィルムを成形した後、この樹脂フィルムを巻取ロールに複数個並列的に嵌挿した紙管と押圧ロールとの間に導き、巻取方向に張力を掛けながら押圧ロールで樹脂フィルム及び紙管を押圧し、紙管に先に巻き取られた樹脂フィルムと次に巻き取られる樹脂フィルムとの間に介在する空気を排除しながら紙管に巻き付けることにより製造される（例えば、特許文献１参照。）。
特開平８−３１０７３４号公報 In general, a roll-shaped scroll in which a resin film such as the stretch film is wound around such a paper tube is generally obtained by first extruding a resin composition obtained by adding a processing aid such as a plasticizer to a thermoplastic resin as described above. The resin film is extruded into a film form from the die in a molten state, cooled to a temperature lower than the heat distortion temperature of the resin, and then stretched to a predetermined thickness. A resin that is led up between a paper tube and a press roll that are inserted in parallel with each other, presses the resin film and the paper tube with the press roll while applying tension in the winding direction, and is wound around the paper tube first. It is manufactured by winding around a paper tube while excluding air interposed between the film and the resin film to be wound next (see, for example, Patent Document 1).
JP-A-8-310734

樹脂フィルムの巻き付けに使用されている従来の紙管は、前述のように、数枚の紙を積層した軸芯用原紙を層状に巻き重ねて接着することにより円筒状の巻芯を形成し、この巻芯の外周面全体に所定の上質紙等を螺旋状等の形態で貼り付けて形成されており、その形状・大きさは、その使用目的や巻き付ける樹脂フィルムの種類、用途によって種々選択されるが、紙管自体の両端縁部は、紙管の軸線に対して直角に切断された状態となっている。 As described above, the conventional paper tube used for wrapping the resin film forms a cylindrical core by laminating and adhering the base paper for shaft core in which several sheets of paper are laminated, It is formed by pasting predetermined high quality paper etc. in the form of a spiral on the entire outer peripheral surface of this core, and its shape and size are variously selected depending on the purpose of use, the type of resin film to be wound, and the purpose of use. However, both end edges of the paper tube itself are cut at right angles to the axis of the paper tube.

このため、紙管製造時、紙管流通時、紙管使用時、ロール状巻物取扱時等の各工程で紙管両端縁部の角（エッジ部）で、誤って指や手等に切傷を生じることがあった。しかも、これらの工程で、紙管の端縁部に誤って無用な打撃、衝撃が加わると、その個所が欠けたり、凹んだりして異物の混入の要因になったり、あるいは巻き付けられる樹脂フィルムの不良原因になったりすることがあった。 For this reason, injuries to fingers or hands at the corners (edges) of both ends of the paper tube during each process such as paper tube manufacturing, paper tube distribution, paper tube use, and roll-shaped scroll handling. It sometimes occurred. In addition, in these processes, if unnecessary impact or impact is accidentally applied to the edge of the paper tube, the portion may be chipped or dented, causing foreign matter to be mixed in or wound around the resin film. It may cause a defect.

また、樹脂フィルムを巻付けたロール状巻物は、熱変形温度以上に長時間晒されると、樹脂フィルム内に残留する内部応力を解消する方向に樹脂フィルムが膨張変形し、巻物の両端面に凹凸が生じることがあり、その結果、膨張変形した樹脂フィルムが紙管の端面や端部に引っ掛かり、樹脂フィルムに破損や破断を発生させる要因ともなっていた。 In addition, when a roll-shaped scroll wound with a resin film is exposed to a temperature higher than the thermal deformation temperature for a long time, the resin film expands and deforms in a direction to eliminate the internal stress remaining in the resin film, and unevenness is formed on both end surfaces of the scroll. As a result, the expanded and deformed resin film is caught on the end face or the end of the paper tube, which causes damage or breakage of the resin film.

さらに、このような紙管に樹脂フィルムを巻き付けてロール状巻物を製造する過程において、巻取ロールに複数個並列的に嵌挿した紙管と紙管との間に生じる僅かな隙間部や隣合部から押圧ロールの表面に不均等な力が働き、これが長時間にわたって作用すると、押圧ロールの表面に痕跡を生じさせ、ロール状巻物の製造やその品質に影響を与えることもあった。 Furthermore, in the process of manufacturing a roll-shaped roll by winding a resin film around such a paper tube, a slight gap or adjacent between a paper tube and a paper tube inserted in parallel on a take-up roll. When an uneven force acts on the surface of the pressing roll from the joint, and this acts for a long time, a trace is generated on the surface of the pressing roll, which may affect the production of the roll-shaped scroll and its quality.

そこで本発明は、紙管両端縁部のエッジ部に指や手等が触れても切傷を生じることがなく、端縁部に打撃や衝撃が加わっても欠けたり、変形したりことを抑えることができ、樹脂フィルムの膨張変形に起因した樹脂フィルムの破損や破断も防止でき、さらに、押圧ロールの表面に痕跡を発生させることもないロール状巻物を提供することを目的としている。 Therefore, the present invention does not cause a cut even if a finger or a hand touches the edge part of both ends of the paper tube, and suppresses the chipping or deformation even if the edge is hit or impacted. An object of the present invention is to provide a roll-shaped scroll that can prevent breakage and breakage of the resin film due to expansion and deformation of the resin film and that does not generate a trace on the surface of the pressing roll.

上記目的を達成するため、本発明のロール状巻物は、紙管の外周面に樹脂フィルムを巻き付けたロール状巻物において、前記紙管は、軸芯用原紙を螺旋状かつ層状に巻回して形成された紙製巻芯の両端縁部に面落部をそれぞれ形成するとともに、少なくとも樹脂フィルムの巻付け面部及び前記面落部に上質紙を螺旋状に巻回した紙管であって、前記樹脂フィルムは、前記面落部を除く巻付け面部に巻き取られていることを特徴としている。 In order to achieve the above object, the roll-shaped scroll of the present invention is a roll-shaped roll in which a resin film is wound around the outer peripheral surface of a paper tube, and the paper tube is formed by winding a base paper for a shaft in a spiral and layered manner. A paper tube in which chamfered portions are formed at both edge portions of the paper core, and at least a resin film is wound around and a high quality paper is spirally wound around the chamfered portion. The film is characterized by being wound on a winding surface portion excluding the chamfered portion.

さらに、本発明のロール状巻物は、前記面落部は、前記紙管の軸線に対する傾斜角度が３０〜６０度の範囲、紙管の軸線方向の寸法が０．３〜３ｍｍの範囲、紙管の径方向の寸法が０．３〜２ｍｍの範囲に、それぞれ形成されていることを特徴としている。 Further, in the roll-shaped scroll of the present invention, the chamfered portion has an inclination angle with respect to the axis of the paper tube of 30 to 60 degrees, a dimension of the paper tube in the axial direction of 0.3 to 3 mm, The diameter dimension of each is formed in the range of 0.3-2 mm, respectively.

本発明のロール状巻物によれば、紙管の端縁部に面落部を形成しているので、指や手等が触れても切傷を生じることがない。また、紙管の端縁部に打撃や衝撃が加わっても、面落部により力が分散することで影響が少なく、欠けたり、変形したりして異物の混入の要因になったり、巻き付けられる樹脂フィルムの不良原因になったりすることもない。さらに、樹脂フィルムが膨張変形して巻物の両端面に凹凸が生じた場合でも、樹脂フィルムが紙管の端面や端部に引っ掛かることがなく、樹脂フィルムに破損や破断を発生させることがない。加えて、紙管に樹脂フィルムを巻き付けてロール状巻物を製造する過程において、押圧ロールの表面に痕跡を生じることがなく、ロール状巻物の製造やその品質に影響を与えることもない。 According to the roll-shaped scroll of the present invention, since the chamfered portion is formed at the edge of the paper tube, no cuts are generated even if a finger or a hand touches it. In addition, even if an impact or impact is applied to the edge of the paper tube, the force is dispersed by the chamfered portion so that there is little influence, and it may be chipped or deformed, causing foreign matter to be mixed in or wound. It does not cause a defective resin film. Furthermore, even when the resin film expands and deforms to cause unevenness on both end faces of the scroll, the resin film is not caught on the end face or end of the paper tube, and the resin film is not damaged or broken. In addition, in the process of manufacturing a roll-shaped roll by winding a resin film around a paper tube, no trace is generated on the surface of the pressing roll, and the manufacture of the roll-shaped roll and its quality are not affected.

紙管１１は、軸芯用原紙を螺旋状かつ層状に巻回して形成した紙製巻芯１２の幅方向両端縁部に面落部１３を形成するとともに、樹脂フィルム１４の巻付け面部１５及び面落部１３に上質紙１６を螺旋状に巻回して形成されている。紙製巻芯１２は、最内層から数枚のライナー紙、原紙、ライナー紙等の軸芯用原紙を積層した所定の厚み・幅を有するものであって、各軸芯用原紙を所定の角度で螺旋状に連続して層状に巻き重ね、各軸芯用原紙同士を酢酸ビニル系の接着剤で接着して長尺の円筒状に形成された後、所定の長さに切断される。紙管１１の形状や大きさは、その使用目的、巻き付けられる樹脂フィルム１４の種類や用途によって種々選択されるが、例えば、業務用の食品包装用ストレッチフィルムを巻き取る紙管の場合は、内径約７５ｍｍ（３インチ）、外径８５〜９０ｍｍ、長さ３００〜５００ｍｍが一般的である。 The paper tube 11 forms a chamfered portion 13 at both edges in the width direction of a paper core 12 formed by spirally and stratifiedly winding an axial base paper, and a winding surface portion 15 of the resin film 14 and High quality paper 16 is spirally wound around the chamfered portion 13. The paper core 12 has a predetermined thickness and width obtained by stacking several core papers such as liner paper, base paper, liner paper, etc. from the innermost layer. Then, the axial core papers are bonded together with a vinyl acetate adhesive to form a long cylindrical shape, and then cut into a predetermined length. The shape and size of the paper tube 11 are variously selected according to the purpose of use and the type and application of the resin film 14 to be wound. For example, in the case of a paper tube for winding a stretch film for food packaging for business use, the inner diameter Approximately 75 mm (3 inches), an outer diameter of 85 to 90 mm, and a length of 300 to 500 mm are common.

前記面落部１３は、長尺円筒状に形成した紙製巻芯１２を樹脂フィルムの幅寸法に対応した所定の長さ寸法に切断するのと同時に、該切断部の外端末角部を所定形状の鉄ロール等で圧縮して面取加工することによって形成することができる。この面落部１３の形状は、紙管１１の外径や厚みに応じて設定することができるが、通常は前記紙管１１の軸線ＣＬに対する傾斜角度θが３０〜６０度の範囲、紙管１１の軸線方向の寸法Ｃ１が０．３〜３ｍｍの範囲、紙管１１の径方向の寸法Ｃ２が０．３〜２ｍｍの範囲に、それぞれ形成することが好ましい。なお、面落部１３の表面は、Ｃ面取りによる円錐状だけでなく、Ｒ面取りによる曲面であってもよく、これらを組み合わせたものであってもよい。 The chamfered portion 13 cuts the paper core 12 formed in a long cylindrical shape into a predetermined length dimension corresponding to the width dimension of the resin film, and at the same time, the outer end corner portion of the cut portion is predetermined. It can be formed by compressing with a shaped iron roll or the like and chamfering. The shape of the chamfered portion 13 can be set in accordance with the outer diameter and thickness of the paper tube 11, but normally, the inclination angle θ with respect to the axis CL of the paper tube 11 is in the range of 30 to 60 degrees. 11 is preferably formed so that the axial dimension C1 is in the range of 0.3 to 3 mm and the radial dimension C2 of the paper tube 11 is in the range of 0.3 to 2 mm. The surface of the chamfered portion 13 is not limited to a conical shape by C chamfering, but may be a curved surface by R chamfering, or a combination thereof.

前記傾斜角度θが３０〜６０度の範囲を外れると、いずれの場合も軸線ＣＬに対して直交する方向に切断した形状に近くなるため、面落部１３を形成した効果が十分に得られなくなる。また、前記各寸法Ｃ１，Ｃ２が小さ過ぎると面落部１３が小さくなって面落部１３の効果が十分に得られなくなり、軸線方向の寸法Ｃ１を大きくし過ぎると、紙管１１の長さに対して面落部１３の長さが大きくなって樹脂フィルム１４を巻き付けるための巻付け面部１５の寸法が短くなり好ましくない。一方、径方向の寸法Ｃ２を大きくし過ぎると、面落部１３が軸線ＣＬに対して直交する方向に切断した形状に近くなり、この場合も面落部１３の効果が十分に得られなくなる。 If the inclination angle θ is out of the range of 30 to 60 degrees, in any case, it becomes close to a shape cut in a direction orthogonal to the axis CL, and thus the effect of forming the chamfered portion 13 cannot be sufficiently obtained. . Further, if the dimensions C1 and C2 are too small, the chamfered portion 13 becomes small and the effect of the chamfered portion 13 cannot be sufficiently obtained. If the dimension C1 in the axial direction is excessively increased, the length of the paper tube 11 is increased. On the other hand, the length of the chamfered portion 13 is increased, and the dimension of the winding surface portion 15 for winding the resin film 14 is shortened. On the other hand, when the radial dimension C2 is excessively increased, the chamfered portion 13 becomes close to a shape cut in a direction orthogonal to the axis CL, and in this case, the effect of the chamfered portion 13 cannot be sufficiently obtained.

樹脂フィルム１４は、例えば、ポリ塩化ビニル、ポリプロピレン、ポリエチレン、ポリ塩化ビニリデン等の熱可塑性樹脂からなる単層又は多層の食品包装用ストレッチフィルムであって、前述のような熱可塑性樹脂に可塑剤等の加工助剤を添加した組成物を押出機に投入し、溶融させて口金からフィルム状に押し出し、熱変形温度以下に冷却してから所定の厚みまで延伸されたものである。この樹脂フィルム１４は、前記面落部１３を除く円筒状外周面を有する前記巻付け面部１５に所定長さで巻き付けられる。これにより、所定長さの樹脂フィルム１４を巻き付けた巻物の両端面から前記面落部１３が所定量突出した状態となる。 The resin film 14 is a single-layer or multi-layer food packaging stretch film made of a thermoplastic resin such as polyvinyl chloride, polypropylene, polyethylene, polyvinylidene chloride, and the like. The composition added with the processing aid is put into an extruder, melted and extruded from the die into a film, cooled to a temperature equal to or lower than the heat distortion temperature, and then stretched to a predetermined thickness. The resin film 14 is wound around the winding surface portion 15 having a cylindrical outer peripheral surface excluding the chamfered portion 13 with a predetermined length. Thereby, the said chamfered part 13 will be in the state which protruded the predetermined amount from the both end surfaces of the roll which wound the resin film 14 of predetermined length.

紙管１１の外周面に樹脂フィルム１４を巻き付けたロール状巻物をこのように形成することにより、紙管１１を製造する工程、紙管１１が流通される工程、樹脂フィルム１４を紙管１１に巻き取る工程等、紙管自体を取り扱う際や、ロール状巻物を巻物収納箱に収納したり、取り出したりする際に、紙管１１の両端縁部の角（エッジ部）が指・手等に当たっても切傷を生じることがない。 By forming a roll-shaped roll in which the resin film 14 is wound around the outer peripheral surface of the paper tube 11 in this manner, a step of manufacturing the paper tube 11, a step of distributing the paper tube 11, and the resin film 14 on the paper tube 11 When handling the paper tube itself, such as in the winding process, or when storing or taking out the roll-shaped scroll in the scroll storage box, the corners (edge portions) of both ends of the paper tube 11 hit the fingers, hands, etc. There will be no cuts.

しかも、これらの工程で、紙管１１の端縁部に打撃や衝撃が加わっても、その個所が面落部１３になっているので力が分散し、影響が少なく、欠けたり凹んだりして異物の混入の要因になることがなく、紙管１１に巻き付けられる樹脂フィルム１４の不良原因となることもない。 In addition, in these steps, even if an impact or impact is applied to the edge of the paper tube 11, the portion is a chamfered portion 13, so that the force is dispersed and the influence is small, and it is chipped or recessed. It does not cause a foreign matter mixture, and does not cause a defect of the resin film 14 wound around the paper tube 11.

また、樹脂フィルム１４を巻付けたロール状巻物が、樹脂フィルム１４の熱変形温度以上に長時間さらされて樹脂フィルム１４内に残留する内部応力を解消する方向に樹脂フィルム１４が膨張して変形し、巻物の両端面に凹凸や波打ちが生じて幅方向両端縁部に樹脂フィルム１４の迫り出しがあっても、紙管１１の両端縁部に面落部１３が形成されるとともに、その面落部１３にも上質紙１７が施されているので、樹脂フィルム１４の迫り出しによる紙管１１の両端縁部への引っかかりが少なくなり、樹脂フィルム１４の破損や破断の発生要因となることもない。 Further, the roll-shaped roll around which the resin film 14 is wound is exposed to a temperature higher than the thermal deformation temperature of the resin film 14 for a long time, and the resin film 14 expands and deforms in a direction to eliminate the internal stress remaining in the resin film 14. Even when unevenness and undulation occur on both end faces of the scroll and the resin film 14 protrudes at both end edges in the width direction, the chamfered portions 13 are formed at both end edges of the paper tube 11, and the surfaces thereof. Since the high-quality paper 17 is also applied to the dropped portion 13, the resin film 14 is less likely to be caught at both edge portions of the paper tube 11 due to the protrusion of the resin film 14, and may cause damage or breakage of the resin film 14. Absent.

加えて、複数個の前記紙管１１を巻取ロールに並列に嵌挿し、前記樹脂フィルム１４を巻き取り方向に張力を掛けながら押圧ロールで樹脂フィルム１４及び紙管１１を押圧することにより、紙管１１に先に巻き取られた樹脂フィルム１４と次に巻き取られる樹脂フィルム１４との間に介在するエアを排除しながら紙管１１に樹脂フィルム１４を順次巻き取ってロール状巻物を製造する際に、両端縁部に面落部１３を形成した紙管１１の場合は、隣接する紙管１１と紙管１１との間で生じる僅かの隙間部乃至隣合部が凹部形状になるので、その個所によって押圧ロールの表面に不均等な力が掛かり難く、押圧ロールの表面に痕跡を生じる現象等が発生せず、ロール状巻物の製造やその品質に悪影響を与えることもない。 In addition, a plurality of the paper tubes 11 are fitted in parallel to the take-up roll, and the resin film 14 and the paper tube 11 are pressed with a pressure roll while applying tension to the resin film 14 in the take-up direction, thereby making the paper A roll-shaped roll is produced by sequentially winding the resin film 14 around the paper tube 11 while eliminating the air interposed between the resin film 14 previously wound around the tube 11 and the resin film 14 wound next. On the other hand, in the case of the paper tube 11 in which the chamfered portion 13 is formed at both edge portions, a slight gap portion or an adjacent portion generated between the adjacent paper tube 11 and the paper tube 11 becomes a concave shape. Depending on the location, an uneven force is not easily applied to the surface of the pressing roll, a phenomenon that causes a trace on the surface of the pressing roll does not occur, and the production of the roll-shaped scroll and its quality are not adversely affected.
