Description

本発明は、巻芯にフィルム又はシートを巻き付けたロール状物の端部に配置される梱包ロール用の当て板部材に関する。   The present invention relates to a backing plate member for a packing roll disposed at an end portion of a roll-like product in which a film or a sheet is wound around a core.

合成樹脂等の材料からなるフィルム、紙や布等のシートは、数百〜数万メートルの長尺な帯状に製造され、巻芯に巻き付けてロール状物として保管される。このようなロール状物では、ロール状物の両端部に木製あるいは熱可塑性樹脂製の当て板部材が配置され、段ボール等により適宜梱包されて保管される。   A film made of a material such as a synthetic resin, a sheet of paper, cloth, or the like is manufactured into a long band of several hundred to several tens of thousands of meters, wound around a core, and stored as a roll. In such a roll-like product, a wooden or thermoplastic resin backing plate member is disposed at both ends of the roll-like product, and is appropriately packed and stored with cardboard or the like.

上記梱包ロール用の当て板部材としては、例えば、ロール径より大きい略正方形状の板材からなり、板材の略中央部分に形成された開口部にロール状物の巻芯を嵌挿させ、ロール状物を倒して宙吊りで支持するものが知られている（例えば、特許文献１参照。）。しかしながら、この略正方形状の当て板部材では、出荷等によりロール状物を保管場所から短い距離を移動させる場合であってもフォークリフト等の運搬手段を用いる必要があり、作業が繁雑となっていた。   As the backing plate member for the packing roll, for example, it is made of a substantially square plate material larger than the roll diameter, and the roll core is inserted into the opening formed in the substantially central portion of the plate material to form a roll shape. There is known a technique in which an object is brought down and supported by hanging in the air (for example, see Patent Document 1). However, with this substantially square-shaped backing plate member, it is necessary to use a transport means such as a forklift even when a roll-like object is moved a short distance from the storage location by shipping or the like, and the work is complicated. .

これに対し、ロール状物の両端部にロール径とほぼ等しい円形の当て板部材を配置して、ロール状物を直立させて保管する方式がある。この方式では、図１１に示すように、ロール状物Ｒを短い距離移動させる場合に、ロール状物Ｒを直立状態から適宜傾けて当て板部材５０の端部５３のみが接地する状態としながらロール状物Ｒを回転させることにより、運搬手段を用いなくても人力で容易に移動させることができる。なお、図１１において、符号６０は当て板部材５０と反対側のロール状物Ｒの端部に配置されたロール径と略等しい円形の当て板部材である。   On the other hand, there is a method in which a circular backing plate member having a diameter substantially equal to the roll diameter is arranged at both ends of the roll-like object, and the roll-like object is stored upright. In this method, as shown in FIG. 11, when the roll-shaped object R is moved for a short distance, the roll-shaped object R is appropriately tilted from the upright state, and only the end portion 53 of the contact plate member 50 is grounded. By rotating the object R, it can be easily moved by human power without using a transportation means. In addition, in FIG. 11, the code | symbol 60 is a circular backing plate member substantially equal to the roll diameter arrange | positioned at the edge part of the roll-shaped object R on the opposite side to the backing plate member 50. FIG.

しかしながら、ロール状物Ｒを傾斜させながら回転させて移動させる場合、図１２に示すように、ロール状物Ｒの重量が当て板部材５０に集中するため、当て板部材５０の接地部分の外周部５３がわずかに変形し、該当て板部材５０を介して重量の応力がロール状物Ｒの端部Ｒ１にかかってしまう。これにより、図１２，１３に示すように、ロール状物Ｒの端部Ｒ１付近に象足と呼ばれるシワＷが発生して、商品価値が低下もしくは商品として出荷することができなくなる問題があった。また、当て板部材の変形を抑制するために当て板部材を金属やコンクリート等で形成することも考えられるが、当て板部材の重量やコストの観点から実用性に乏しい問題があった。   However, when the roll-shaped object R is rotated and moved while being tilted, the weight of the roll-shaped object R is concentrated on the contact plate member 50 as shown in FIG. 53 is slightly deformed, and the stress of weight is applied to the end R1 of the roll-like object R via the plate member 50. As a result, as shown in FIGS. 12 and 13, wrinkles W called elephant legs are generated in the vicinity of the end R <b> 1 of the roll-like object R, and there is a problem that the commercial value is lowered or cannot be shipped as a commercial product. . Moreover, in order to suppress the deformation of the contact plate member, it is conceivable to form the contact plate member from metal, concrete, or the like. However, there is a problem that the practicality is poor from the viewpoint of the weight and cost of the contact plate member.

図１〜３に示すように、この発明の梱包ロール用の当て板部材１０は、巻芯Ｒ２にフィルム又はシートを巻着したロール状物Ｒの端部Ｒ１に配置される円形の当て板部材である。この当て板部材１０は、一つの面側のフィルム端部Ｒ１に当接して該フィルム端部Ｒ１を支持する接面部１１と、ロール状物Ｒの立設時に接地される接地部１２とを有するとともに、ロール状物Ｒの端部Ｒ１と接地部１２との間に接地部１２の外周部１３の変形を吸収する吸収部１５が形成されている。   As shown in FIGS. 1 to 3, the backing plate member 10 for a packaging roll according to the present invention is a circular backing plate member disposed at an end R <b> 1 of a roll-like object R in which a film or a sheet is wound around a core R <b> 2. It is. The backing plate member 10 has a contact surface portion 11 that contacts the film end portion R1 on one surface side and supports the film end portion R1, and a grounding portion 12 that is grounded when the roll-shaped object R is erected. In addition, an absorbing portion 15 that absorbs deformation of the outer peripheral portion 13 of the grounding portion 12 is formed between the end portion R1 of the roll-shaped object R and the grounding portion 12.

図において、符号１４はロール状物Ｒの巻芯Ｒ２を固定するための開口穴部、２０は当て板部材１０と反対側のロール状物Ｒの端部Ｒ１に配置されたロール径と略等しい円形の当て板部材、Ｒ３はロール状物Ｒの巻芯Ｒ２に開口穴部１４を介して嵌挿されて当て板部材１０，２０をロール状物Ｒに固定するための固定部材、Ｒ４はロール状物Ｒを梱包するためにその外周に巻き付けられる段ボール等からなる保護シートである。   In the figure, reference numeral 14 is an opening hole for fixing the core R2 of the roll-shaped object R, and 20 is substantially equal to the roll diameter arranged at the end R1 of the roll-shaped object R on the opposite side of the backing plate member 10. A circular backing plate member, R3 is a fixing member for fixing the backing plate members 10 and 20 to the roll-like object R by being inserted into the core R2 of the roll-like product R through the opening hole 14, and R4 is a roll. It is a protective sheet made of corrugated cardboard or the like that is wound around the outer periphery of the product R for packing.

この当て板部材１０は、ポリプロピレン（ＰＰ）、アクリロニトリルブタジエンスチレン（ＡＢＳ）等の熱可塑性樹脂製、あるいは、木製等の安価で成形性に優れるとともに、軽量で耐久性にも優れた適宜の材料で形成される。   The backing plate member 10 is made of a thermoplastic resin such as polypropylene (PP) or acrylonitrile butadiene styrene (ABS), or an appropriate material that is inexpensive and excellent in moldability, lightweight, and excellent in durability. It is formed.

図１〜図４に示す第１実施例の当て板部材１０Ａは、接面部１１がロール状物Ｒのロール径より小径な小径板面部材１１Ａよりなり、接地部１２が小径板面部材１１Ａと同心状に配置された大径板面部材１２Ａからなる。この当て板部材１０Ａは、小径板面部材１１Ａと大径板面部材１２Ａとを重ね合わせたり、あるいは、一体成形で製作することにより簡易に構成することができる。また、当て板部材１０Ａは、ロール状物Ｒの巻芯に開口穴部１４を介して適宜の固定部材により固定される。この当て板部材１０Ａでは、吸収部１５が空間部１５Ａとして構成される。   The contact plate member 10A of the first embodiment shown in FIGS. 1 to 4 is composed of a small-diameter plate surface member 11A whose contact surface portion 11 is smaller in diameter than the roll diameter of the roll-shaped object R, and the ground contact portion 12 is the same as the small-diameter plate surface member 11A. It consists of a large-diameter plate surface member 12A arranged concentrically. The contact plate member 10A can be simply configured by superimposing the small-diameter plate surface member 11A and the large-diameter plate surface member 12A or manufacturing them by integral molding. Further, the backing plate member 10 </ b> A is fixed to the core of the roll-shaped object R by an appropriate fixing member through the opening hole 14. In this backing plate member 10A, the absorbing portion 15 is configured as a space portion 15A.

小径板面部材１１Ａ及び大径板面部材１２Ａの厚みとしては、吸収部１５（空間部１５Ａ）の高さを十分に確保できるとともに、ロール状物Ｒの傾斜時に破損しない程度の強度があればよく、例えばそれぞれ５ｍｍ〜４０ｍｍである。小径板面部材１１Ａの厚みが５ｍｍより薄い場合、吸収部１５の高さを十分に確保することが困難であり、ロール状物Ｒの傾斜時にロール状物Ｒの端部Ｒ１が大径板面部材１２Ａに接触する恐れがある。一方、大径板面部材１２Ａの厚みが５ｍｍより薄い場合、ロール状物Ｒの傾斜時に破損する恐れがある。また、小径板面部材１１Ａの厚みが４０ｍｍより厚い場合、製造コストがかさんで経済的に不利となる。大径板面部材１２Ａの厚みが４０ｍｍより厚い場合も同様に製造コストがかさんで経済的に不利となる。   As the thickness of the small-diameter plate surface member 11A and the large-diameter plate surface member 12A, if the height of the absorption portion 15 (space portion 15A) can be sufficiently secured, and the strength is such that the roll-shaped object R is not damaged. Well, for example, each is 5 mm to 40 mm. When the thickness of the small-diameter plate surface member 11A is less than 5 mm, it is difficult to ensure a sufficient height of the absorbing portion 15, and the end portion R1 of the roll-shaped material R is a large-diameter plate surface when the roll-shaped material R is inclined. There is a risk of contact with the member 12A. On the other hand, when the thickness of the large-diameter plate surface member 12A is thinner than 5 mm, the roll-shaped object R may be damaged when it is inclined. Further, when the thickness of the small-diameter plate surface member 11A is thicker than 40 mm, it is economically disadvantageous due to the high manufacturing cost. Similarly, when the thickness of the large-diameter plate surface member 12A is thicker than 40 mm, it is economically disadvantageous due to the high manufacturing cost.

小径板面部材１１Ａの直径は、吸収部１５（空間部１５Ａ）の幅を十分に確保できるとともに、ロール状物Ｒの端部Ｒ１を支持することが可能であればよい。例えば、（ロール状物Ｒの直径の１／３）〜（ロール状物Ｒの直径−２０ｍｍ）である。小径板面部材１１Ａの直径がロール状物Ｒの直径の１／３ｍｍより小さい場合、ロール状物Ｒの直立時にロール状物Ｒの端部Ｒ１を支持することが不十分となり、直立時の安定性が確保できなくなる。また、小径板面部材１１Ａの直径がロール状物Ｒの直径−２０ｍｍより大きい場合、吸収部１５の幅を十分に確保することが困難であり、ロール状物Ｒの傾斜時に良好な吸収効果を得ることができない恐れがある。   The diameter of the small-diameter plate surface member 11A only needs to be able to sufficiently secure the width of the absorbing portion 15 (space portion 15A) and to support the end portion R1 of the roll-shaped object R. For example, it is (1/3 of the diameter of the roll-shaped product R) to (diameter of the roll-shaped product R−20 mm). When the diameter of the small-diameter plate surface member 11A is smaller than 1/3 mm of the diameter of the roll-shaped object R, it becomes insufficient to support the end R1 of the roll-shaped object R when the roll-shaped object R stands upright, and stability when standing upright Sex cannot be secured. In addition, when the diameter of the small-diameter plate surface member 11A is larger than the diameter of the roll-shaped object R −20 mm, it is difficult to sufficiently secure the width of the absorbing portion 15, and a good absorption effect is obtained when the roll-shaped object R is inclined. There is a fear that you cannot get.

大径板面部材１２Ａの直径は、ロール状物Ｒの直立時の安定性を確保するとともに、ロール状物Ｒの保管時に必要なスペースが広くなりすぎることを防止することが可能であればよい。例えば、（ロール状物Ｒの直径−１０ｍｍ）〜（ロール状物Ｒの直径＋４０ｍｍ）である。大径板面部材１２Ａの直径がロール状物Ｒの直径−１０ｍｍより小さい場合、ロール状物Ｒの下側の端部Ｒ１部分の保護部がなくなり、保管や移動時に他の物との接触等で損傷を受ける恐れがある。また、大径板面部材１２Ａの直径がロール状物Ｒの直径＋４０ｍｍより大きい場合、ロール状物Ｒの外周部分から大径板面部材１２Ａが必要以上に突出して保管時に必要なスペースが広くなりすぎる恐れがある。   The diameter of the large-diameter plate surface member 12A only needs to ensure the stability when the roll-shaped object R is upright and prevent the space necessary for storing the roll-shaped object R from becoming too wide. . For example, (the diameter of the roll-shaped object R−10 mm) to (the diameter of the roll-shaped object R + 40 mm). When the diameter of the large-diameter plate surface member 12A is smaller than the diameter of the roll-shaped object R−10 mm, the protective part at the lower end R1 of the roll-shaped object R is lost, and contact with other objects during storage or movement May cause damage. Further, when the diameter of the large-diameter plate surface member 12A is larger than the diameter of the roll-shaped object R + 40 mm, the large-diameter plate surface member 12A protrudes more than necessary from the outer peripheral portion of the roll-shaped object R, and the necessary space for storage becomes wide. There is a risk of too much.

第１実施例の当て板部材１０Ａでは、図４に示すように、ロール状物Ｒを傾斜させた場合、ロール状物Ｒの重量の応力が大径板面部材１２Ａにかかるため、外周部１３がロール状物Ｒ側へわずかに変形する。その際、ロール状物Ｒの端部Ｒ１と大径板面部材１２Ａとの間に吸収部１５である空間部１５Ａが形成されていることにより、外周部１３が変形してもロール状物Ｒの端部Ｒ１に接することがないため、ロール状物Ｒの端部Ｒ１が重量の応力の影響を受けることがない。従って、ロール状物Ｒを傾斜させながら回転させて移動させた場合にロール状物Ｒにシワが発生することを効果的に抑制することができる。   In the caulking plate member 10A of the first embodiment, as shown in FIG. 4, when the roll-shaped object R is inclined, the stress of the weight of the roll-shaped object R is applied to the large-diameter plate surface member 12A. Slightly deforms toward the roll R side. At that time, since the space portion 15A which is the absorbing portion 15 is formed between the end portion R1 of the roll-shaped object R and the large-diameter plate surface member 12A, the roll-shaped material R even if the outer peripheral portion 13 is deformed. Therefore, the end R1 of the roll-shaped object R is not affected by the stress of weight. Therefore, it is possible to effectively suppress the occurrence of wrinkles on the roll-shaped object R when the roll-shaped object R is rotated and moved while being inclined.

図５〜図７に示す第２実施例の当て板部材１０Ｂは、接面部１１が小径部１１Ｂで接地部１２が大径部１２Ｂである円錐台形状に構成される。この当て板部材１０Ｂは、小径部１１Ｂと大径部１２Ｂとを一体成形により容易に構成することができる。また、この当て板部材１０Ｂでは、吸収部１５が空間部１５Ｂとして構成される。なお、以下の実施例において、第１実施例と同一の符号は同一の構成を表すものとして、その説明を省略する。   The contact plate member 10B of the second embodiment shown in FIGS. 5 to 7 has a truncated cone shape in which the contact surface portion 11 is a small diameter portion 11B and the grounding portion 12 is a large diameter portion 12B. The backing plate member 10B can be easily configured by integrally molding the small diameter portion 11B and the large diameter portion 12B. Moreover, in this contact plate member 10B, the absorption part 15 is comprised as the space part 15B. In the following embodiments, the same reference numerals as those in the first embodiment represent the same configurations, and the description thereof is omitted.

小径部１１Ｂの直径は、前記小径板面部材１１Ａと同様に、吸収部１５（空間部１５Ａ）の幅を十分に確保できるとともに、ロール状物Ｒの端部Ｒ１を支持することが可能であればよく、例えば、（ロール状物Ｒの直径の１／３）〜（ロール状物Ｒの直径−２０ｍｍ）である。また、大径部１２Ｂの直径も、前記大径板面部材１２Ａと同様に、ロール状物Ｒの直立時の安定性を確保するとともに、ロール状物Ｒの保管時に必要なスペースが広くなりすぎることを防止することが可能であればよく、例えば、（ロール状物Ｒの直径−１０ｍｍ）〜（ロール状物Ｒの直径＋４０ｍｍ）である。   The diameter of the small-diameter portion 11B can secure a sufficient width of the absorbing portion 15 (space portion 15A) and can support the end portion R1 of the roll-like object R, similarly to the small-diameter plate surface member 11A. What is necessary is just (1/3 of the diameter of the roll-shaped object R)-(diameter of the roll-shaped object R-20mm), for example. Further, the diameter of the large diameter portion 12B, as well as the large diameter plate surface member 12A, ensures the stability when the roll-shaped object R is upright, and the space necessary for storing the roll-shaped object R becomes too wide. It is only necessary to be able to prevent this, for example, (the diameter of the roll-shaped material R−10 mm) to (the diameter of the roll-shaped material R + 40 mm).

小径部１１Ｂと大径部１２Ｂとの間隔、すなわち、吸収部１５の高さは、ロール状物Ｒの傾斜時にロール状物Ｒの端部Ｒ１が大径部１２Ｂと接触しない程度であればよく、例えば、５〜４０ｍｍである。吸収部１５の高さが５ｍｍより低い場合、吸収部１５の高さが不十分で、ロール状物Ｒの傾斜時にロール状物Ｒの端部Ｒ１が大径部１２Ｂに接触する恐れがある。吸収部１５の高さが４０ｍｍより高い場合、当て板部材１０Ｂが必要以上に大きくなり、製造コストがかさんで経済的に不利となる。   The distance between the small-diameter portion 11B and the large-diameter portion 12B, that is, the height of the absorbing portion 15 only needs to be such that the end R1 of the roll-shaped object R does not contact the large-diameter portion 12B when the roll-shaped object R is inclined. For example, it is 5-40 mm. When the height of the absorbing portion 15 is lower than 5 mm, the height of the absorbing portion 15 is insufficient, and the end portion R1 of the roll-shaped object R may come into contact with the large-diameter portion 12B when the roll-shaped object R is inclined. When the height of the absorption part 15 is higher than 40 mm, the backing plate member 10B becomes unnecessarily large, which is economically disadvantageous due to the high manufacturing cost.

第２実施例の当て板部材１０Ｂでは、図７に示すように、ロール状物Ｒを傾斜させた場合、ロール状物Ｒの重量の応力が大径部１２Ｂにかかるため、外周部１３がロール状物Ｒ側へわずかに変形する。その際、ロール状物Ｒの端部Ｒ１と大径部１２Ｂとの間に吸収部１５である空間部１５Ｂが形成されていることにより、第１実施例と同様に外周部１３が変形してもロール状物Ｒの端部Ｒ１に接することがない。従って、ロール状物Ｒの端部Ｒ１が重量の応力の影響を受けることがなく、ロール状物Ｒを傾斜させながら回転させて移動させた場合にロール状物Ｒにシワが発生することを効果的に抑制することができる。   In the backing plate member 10B of the second embodiment, as shown in FIG. 7, when the roll-shaped object R is inclined, the stress of the weight of the roll-shaped object R is applied to the large-diameter portion 12B. Slightly deforms to the shape R side. At that time, the outer peripheral portion 13 is deformed similarly to the first embodiment because the space portion 15B which is the absorbing portion 15 is formed between the end portion R1 of the roll R and the large diameter portion 12B. Also does not contact the end R1 of the roll R. Therefore, the end R1 of the roll-shaped object R is not affected by the stress of weight, and it is effective that wrinkles are generated in the roll-shaped object R when the roll-shaped object R is rotated and moved while being inclined. Can be suppressed.

図８〜図１０に示す第３実施例の当て板部材１０Ｃは、接面部１１が小径板面部材１１Ａであるとともに、接地部１２が大径板面部材１２Ａであり、吸収部１５が弾性部１５Ｃとして構成される。弾性部１５Ｃは、吸収部１５として外周部１３の変形を吸収することに加え、ロール状物Ｒの直立時に端部Ｒ１を弾性支持することができる。弾性部１５Ｃとしては、当て板部材１０Ｃよりも軟性な適宜の材料であればよく、例えば多孔質ウレタンフォーム等が好適に用いられる。   The contact plate member 10C of the third embodiment shown in FIGS. 8 to 10 has a contact surface portion 11 which is a small diameter plate surface member 11A, a grounding portion 12 which is a large diameter plate surface member 12A, and an absorption portion 15 which is an elastic portion. Configured as 15C. The elastic portion 15 </ b> C can elastically support the end portion R <b> 1 when the roll-shaped object R stands upright in addition to absorbing the deformation of the outer peripheral portion 13 as the absorbing portion 15. The elastic portion 15C may be any appropriate material that is softer than the backing plate member 10C. For example, porous urethane foam or the like is preferably used.

この弾性部１５Ｃでは、厚みが小径板面部材１１Ａの厚みと等しく構成され、例えば、５〜４０ｍｍである。弾性部１５Ｃの厚みが５ｍｍより薄い場合、厚みが不十分でロール状物Ｒの傾斜時に良好な吸収効果を得ることが困難となる。４０ｍｍより厚い場合、製造コストがかさんで経済的に不利となる。また、弾性部１５Ｃでは、外径がロール状物Ｒの直径あるいは大径板面部材１２Ａの直径と同径に構成される。   In this elastic portion 15C, the thickness is configured to be equal to the thickness of the small-diameter plate surface member 11A, and is, for example, 5 to 40 mm. When the thickness of the elastic part 15C is thinner than 5 mm, the thickness is insufficient and it is difficult to obtain a good absorption effect when the roll-shaped object R is inclined. If it is thicker than 40 mm, the manufacturing cost is high and it is economically disadvantageous. Further, in the elastic portion 15C, the outer diameter is configured to be the same as the diameter of the roll-shaped object R or the diameter of the large-diameter plate surface member 12A.

第３実施例の当て板部材１０Ｃでは、図８に示すように、ロール状物Ｒの直立時に端部Ｒ１を弾性支持することができるため、ロール状物Ｒの外周端部がたわむ等してシワが発生することを効果的に抑制することができる。また、図１０に示すように、ロール状物Ｒを傾斜させた場合には、ロール状物Ｒの重量の応力が大径板面部材１２Ａにかかるため、外周部１３がロール状物Ｒ側へわずかに変形する。その際、ロール状物Ｒの端部Ｒ１と大径板面部材１２Ａとの間に吸収部１５である弾性部１５Ｃが形成されていることにより、外周部１３の変形が弾性的に吸収されてロール状物Ｒの端部Ｒ１が重量の応力の影響を受けることがない。従って、ロール状物Ｒを傾斜させながら回転させて移動させた場合にロール状物Ｒにシワが発生することを効果的に抑制することができる。   In the caulking plate member 10C of the third embodiment, as shown in FIG. 8, since the end R1 can be elastically supported when the roll-shaped object R is upright, the outer peripheral end of the roll-shaped object R is bent. Generation of wrinkles can be effectively suppressed. Moreover, as shown in FIG. 10, when the roll-shaped object R is inclined, the weight stress of the roll-shaped object R is applied to the large-diameter plate surface member 12A. Slightly deforms. At that time, the deformation of the outer peripheral portion 13 is elastically absorbed by the elastic portion 15C that is the absorbing portion 15 formed between the end portion R1 of the roll-shaped object R and the large-diameter plate member 12A. The end R1 of the roll R is not affected by weight stress. Therefore, it is possible to effectively suppress the occurrence of wrinkles on the roll-shaped object R when the roll-shaped object R is rotated and moved while being inclined.

次に、以下の試作例１〜７が端部に配置されたロール状物をそれぞれ１０本ずつ用意し、直立状態から約３０°傾斜させて、ロール状物を回転させながら直線方向に５ｍ移動させた後、端部付近にシワが発生したロール状物の本数を比較した。なお、ロール状物は、厚み１２μｍ、長さ１２０００ｍ、幅１０００ｍｍの二軸延伸ＰＥＴフィルムで、外径が４４８ｍｍであった。   Next, each of the following prototype examples 1 to 7 is prepared with 10 rolls arranged at the end, inclined by about 30 ° from the upright state, and moved 5 m in the linear direction while rotating the rolls.
