Description

本発明は、ロール体の搬送用資材に関する。   The present invention relates to a material for conveying a roll body.

従来、いわゆるフィルムロールなどのロール体を搬送・保管する搬送用資材が各種提案されている（例えば、特許文献１参照）。   Conventionally, various materials for transporting and storing a roll body such as a so-called film roll have been proposed (see, for example, Patent Document 1).

特許文献１には、特許文献１の第１図に示されるように、巻取りコア（２８）（括弧内の数字は、特許文献１に記載される符号を示す。以下、同様）上に巻かれた完成ロール（２７）を支持する端壁（１）が開示されている。この端壁（１）の中央には、凸状の挿入ペグ（２）が設けられており、この挿入ペグ（２）を巻取りコア（２８）内に挿入することで、完成ロール（２７）を支持する。また、端壁（１）は、完成ロール（２７）側となる内側に向く前面と、外側に向く背面とを有する。特許文献１の第３図に示されるように、背面には、端壁（１）の中心から放射状に延びる複数のラジアルリブ（５）と、円形に形成される環状リブ（１４）とが設けられる。   In Patent Document 1, as shown in FIG. 1 of Patent Document 1, the winding core (28) (the numbers in parentheses indicate the reference numerals described in Patent Document 1. The same applies hereinafter). An end wall (1) that supports the finished roll (27) is disclosed. A convex insertion peg (2) is provided at the center of the end wall (1). By inserting the insertion peg (2) into the winding core (28), a completed roll (27) Support. Moreover, an end wall (1) has the front surface which faces the inner side used as the completion roll (27) side, and the back surface which faces an outer side. As shown in FIG. 3 of Patent Document 1, a plurality of radial ribs (5) extending radially from the center of the end wall (1) and an annular rib (14) formed in a circular shape are provided on the back surface. .

ところで、近年、この種の搬送用資材には、更なる軽量化が要望されている。しかし、搬送用資材を単に軽量化してしまうと、その分、剛性が低下してしまい、ロール体を支持するために必要な支持強度を確保することが難しい場合がある。このため、必要な支持強度を確保しつつ、搬送用資材を軽量化できる技術が求められている。   By the way, in recent years, further weight reduction is demanded for this kind of material for conveyance. However, if the weight of the transport material is simply reduced, the rigidity decreases accordingly, and it may be difficult to secure the support strength necessary to support the roll body. For this reason, there is a need for a technique that can reduce the weight of the transport material while ensuring the necessary support strength.

The opposing outer wall 33, the upper wall 35 that connects the upper end of the inner wall 31 and the upper end of the outer wall 33, the lower wall 36 that connects the lower end of the inner wall 31 and the lower end of the outer wall 33, and the inner wall 31 And a pair of side wall portions 37 that connect the side end of the outer wall portion 33 and the side end of the outer wall portion 33. Here, the upper wall part 35, the lower wall part 36, and the pair of side wall parts 37 constitute the "peripheral wall part that connects the outer peripheries of the inner wall part and the outer wall part" referred to in the present invention. This corresponds to “four sides”.

また、支持部材３０は、軸芯２１（図２参照）を支持するための支持孔４１と、上壁部３５に設けられる上側位置規制部４２と、下壁部３６に設けられる下側位置規制部４３と、鉛直方向に沿って溝状に形成される複数の溝状リブ４５ａ，４５ｂと、を有する。さらに、支持部材３０の中空部３２には、支持部材３０の剛性を高めるための補強材４６、複数のフレーム部材４７Ｕ，４７Ｄ，４７Ｓが設けられる。   The support member 30 has a support hole 41 for supporting the shaft core 21 (see FIG. 2), an upper position restricting portion 42 provided on the upper wall portion 35, and a lower position restricting portion provided on the lower wall portion 36. It has a portion 43 and a plurality of groove-like ribs 45a, 45b formed in a groove shape along the vertical direction. Further, the hollow portion 32 of the support member 30 is provided with a reinforcing material 46 for increasing the rigidity of the support member 30 and a plurality of frame members 47U, 47D, 47S.

支持孔４１は、ここでは、支持部材３０の中心に形成される円形状の貫通穴であり、内壁部３１及び外壁部３３を厚み方向に貫通して設けられる。支持孔４１は、円形状の他、正方形状や多角形状を含む各種の形状から選択可能である。   Here, the support hole 41 is a circular through hole formed at the center of the support member 30 and is provided through the inner wall portion 31 and the outer wall portion 33 in the thickness direction. The support hole 41 can be selected from various shapes including a square shape and a polygonal shape in addition to a circular shape.

上側位置規制部４２と下側位置規制部４３は、互いに噛み合うことが可能な形状に形成されており、支持部材３０の上に他の支持部材３０を積み上げる際、支持部材３０の上側位置規制部４２と他の支持部材３０の下側位置規制部４３とが噛み合って嵌合する。これにより、他の支持部材３０の幅方向及び厚み方向の位置が正規の積み上げ位置に規制される。なお、支持部材３０の上に、２個以上の他の支持部材３０を順次積み上げていくことで、ロール体２０（図２参照）を３段以上に積み上げることも可能である。   The upper position restricting portion 42 and the lower position restricting portion 43 are formed in shapes that can be engaged with each other, and when the other support member 30 is stacked on the support member 30, the upper position restricting portion of the support member 30. 42 and the lower position restricting portion 43 of the other support member 30 are engaged with each other. Thereby, the position of the width direction and the thickness direction of the other support member 30 is regulated to a regular stacked position. It is also possible to stack the roll bodies 20 (see FIG. 2) in three or more stages by sequentially stacking two or more other support members 30 on the support member 30.

溝状リブ４５ａは、支持孔４１を挟んで幅方向両側のそれぞれに複数（例えば、４本程度）配置される。また、支持孔４１の上側には、複数（例えば、５本程度）の溝状リブ４５ｂが配置され、これら上側の溝状リブ４５ｂの延長線上でかつ支持孔４１の下側にも、複数（例えば、５本程度）の溝状リブ４５ｂが配置される。   A plurality of (for example, about four) groove-like ribs 45a are arranged on both sides in the width direction across the support hole 41. In addition, a plurality of (for example, about five) groove-like ribs 45b are arranged on the upper side of the support hole 41, and a plurality (for example, on the extension line of the upper groove-like rib 45b and on the lower side of the support hole 41 are also provided. For example, about 5) groove-like ribs 45b are arranged.

このような複数の溝状リブ４５ａ，４５ｂは、鉛直方向に沿って溝状に延びる凹み４８により、平行に配列されて形成される。   The plurality of groove-like ribs 45a, 45b are formed in parallel by recesses 48 extending in a groove shape along the vertical direction.

すなわち、図４に示すように、内壁部３１又は外壁部３３の少なくとも一方の壁側（この例では、外壁部３３側）から他方の壁側（この例では、内壁部３１側）に向けて凹む溝状の凹み４８を形成し、この凹み４８の先端面４８ａを他方の壁の裏面に溶着する。このような凹み４８を形成することにより、凹み４８の周囲に溝状リブ４５ａ，４５ｂを形成することができる。また、他方の壁側から一方の壁側に向けて凹んで円形リブ４５ｃを形成する円形の凹み４９を設け、この凹み４９の先端面４９ａと凹み４８の先端面４８ａとを溶着してもよい。凹み４８，４９は、例えば、ブロー成形において、内壁部３１又は外壁部３３の少なくとも一方の壁を成形する金型成形面に凸部を適宜設け、この凸部に沿って成形材料を形成するによって得ることができる。   That is, as shown in FIG. 4, from at least one wall side (in this example, the outer wall part 33 side) of the inner wall part 31 or the outer wall part 33 toward the other wall side (in this example, the inner wall part 31 side). A concave groove 48 is formed, and the front end surface 48a of the concave 48 is welded to the back surface of the other wall. By forming such a recess 48, groove-like ribs 45 a and 45 b can be formed around the recess 48. Further, a circular recess 49 that forms a circular rib 45c that is recessed from the other wall side toward the one wall side may be provided, and the tip surface 49a of the recess 49 and the tip surface 48a of the recess 48 may be welded. . For example, in the blow molding, the recesses 48 and 49 are formed by appropriately providing a convex part on a mold molding surface for molding at least one wall of the inner wall part 31 or the outer wall part 33 and forming a molding material along the convex part. Can be obtained.

なお、支持部材３０の四隅やその近傍などには、円形リブ４５ｃ（図３参照）や、溝状リブ４５ａ，４５ｂよりも短い溝状リブ４５ｄ（図３参照）を適宜設けることもできる。支持部材３０に設ける各種のリブの構成、本数、配置は、この例に格別に限定されるものではなく任意である。   It should be noted that circular ribs 45c (see FIG. 3) or groove-like ribs 45d (see FIG. 3) shorter than the groove-like ribs 45a and 45b may be provided as appropriate at the four corners of the support member 30 or in the vicinity thereof. The configuration, number, and arrangement of the various ribs provided on the support member 30 are not particularly limited to this example and are arbitrary.

図３に示すように、補強材４６は、支持孔４１の直下に設けられており、支持孔４１の下端近傍から下壁部３６（本発明にいう「周壁部の下端」に相当）に向けて鉛直方向に延びる。この例では、下側の２本の溝状リブ４５ｂの間を延びるように補強材４６を支持孔４１の直下に設ける。   As shown in FIG. 3, the reinforcing member 46 is provided directly below the support hole 41, and is directed from the vicinity of the lower end of the support hole 41 toward the lower wall portion 36 (corresponding to “the lower end of the peripheral wall portion” in the present invention). Extend vertically. In this example, the reinforcing member 46 is provided directly below the support hole 41 so as to extend between the two lower groove ribs 45b.

複数のフレーム部材４７Ｕ，４７Ｄ，４７Ｓは、それぞれ、上壁部３５、下壁部３６及び一対の側壁部３７に沿って設けられる。なお、以下の説明において、フレーム部材４７Ｕ，４７Ｄ，４７Ｓをまとめて称する場合、「フレーム部材４７」と記載する。   The plurality of frame members 47U, 47D, and 47S are provided along the upper wall portion 35, the lower wall portion 36, and the pair of side wall portions 37, respectively. In the following description, when the frame members 47U, 47D, and 47S are collectively referred to, they are described as “frame member 47”.

以上のように構成される補強材４６やフレーム部材４７は、内壁部３１や外壁部３３を形成する支持部材３０の本体部分（中空成形体）よりも剛性の高い材料から選択される。例えば、補強材４６やフレーム部材４７の構成材料には、鉄系やアルミニウム系の金属材料を好適に用いることができるが、ガラス繊維や炭素繊維を含む繊維強化樹脂を用いてもよい。また、補強材４６やフレーム部材４７の形状は、パイプ形状や断面Ｈ形、断面Ｉ形などを含む各種の形状から選択可能である。   The reinforcing member 46 and the frame member 47 configured as described above are selected from materials having higher rigidity than the main body portion (hollow molded body) of the support member 30 that forms the inner wall portion 31 and the outer wall portion 33. For example, as a constituent material of the reinforcing member 46 and the frame member 47, an iron-based or aluminum-based metal material can be suitably used, but a fiber reinforced resin containing glass fiber or carbon fiber may be used. Further, the shape of the reinforcing member 46 and the frame member 47 can be selected from various shapes including a pipe shape, a cross-section H shape, a cross-section I shape, and the like.

また、補強材４６やフレーム部材４７は、内壁部３１及び外壁部３３の内面に接触させることが好ましい。   Further, the reinforcing material 46 and the frame member 47 are preferably brought into contact with the inner surfaces of the inner wall portion 31 and the outer wall portion 33.

例えば、図４に示すように、内壁部３１及び外壁部３３のそれぞれの内面に内側に突出すると凸部５１を形成し、この凸部５１の先端面５２（本発明にいう「接触面」に相当）を補強材４６やフレーム部材４７と接触させる。   For example, as shown in FIG. 4, when projecting inwardly on the inner surfaces of the inner wall portion 31 and the outer wall portion 33, a convex portion 51 is formed, and the front end surface 52 of the convex portion 51 (the “contact surface” in the present invention) Equivalent) is brought into contact with the reinforcing member 46 and the frame member 47.

さらに、補強材４６やフレーム部材４７は、支持部材３０に設けた開口部５３より挿入することができる。   Further, the reinforcing member 46 and the frame member 47 can be inserted from the opening 53 provided in the support member 30.

例えば、図５に示すように、補強材４６の場合、下壁部３６に開口部５３を設け、この開口部５３から補強材４６を挿入することができる。そして、開口部５３を任意の形状（この例では、断面コの字状）の閉塞材５５で塞ぐ。この際、補強材４６の端部と嵌合可能な嵌合部５５ａを閉塞材５５の裏面側に設けることにより、挿入された補強材４６と閉塞材５５とを嵌合した状態で、開口部５３を閉塞材５５で塞ぐことができる。なお、４本のフレーム部材４７の場合についても同様であり、支持部材３０の４つの角部に開口部５３を設け、この開口部５３からフレーム部材４７を挿入し、挿入したフレーム部材４７の端部と閉塞材５５とを嵌合した状態で、開口部５３を閉塞材５５で塞ぐことができる。   For example, as shown in FIG. 5, in the case of the reinforcing material 46, an opening 53 can be provided in the lower wall portion 36, and the reinforcing material 46 can be inserted from the opening 53. Then, the opening 53 is closed with a closing material 55 having an arbitrary shape (in this example, a U-shaped cross section). At this time, the fitting portion 55a that can be fitted to the end portion of the reinforcing member 46 is provided on the back surface side of the closing member 55, so that the inserted reinforcing member 46 and the closing member 55 are fitted in the opening portion. 53 can be closed with the closing material 55. The same applies to the case of the four frame members 47, and openings 53 are provided at the four corners of the support member 30, and the frame member 47 is inserted through the openings 53, and the end of the inserted frame member 47. The opening 53 can be closed with the closing material 55 in a state where the portion and the closing material 55 are fitted.

（軸部材１３の構成）
図６（ａ）に示すように、軸部材１３は、支持孔４１に嵌め込まれる円筒状の基軸部１３ａと、この基軸部１３ａの外側の端部に設けられる鍔部１３ｂとを有する。この例では、ロール体２０の軸芯２１がシート２２の軸方向の端面２２ａから突出していない場合に、軸芯２１の延長部品として軸部材１３を端部２１ａに挿入する。これにより、軸部材１３を介して軸芯２１の端部２１ａを支持孔４１に支持させることができる。 (Configuration of shaft member 13)
As shown in FIG. 6A, the shaft member 13 includes a cylindrical base shaft portion 13a that is fitted into the support hole 41, and a flange portion 13b that is provided at an outer end portion of the base shaft portion 13a. In this example, when the shaft core 21 of the roll body 20 does not protrude from the end surface 22 a in the axial direction of the sheet 22, the shaft member 13 is inserted into the end portion 21 a as an extension part of the shaft core 21. Thereby, the end 21 a of the shaft core 21 can be supported by the support hole 41 via the shaft member 13.

また、図６（ｂ）に示すように、ロール体２０の軸芯２１がシート２２の端面２２ａから突出している場合においても、軸芯２１の端部２１ａに軸部材１３を挿入し、挿入した軸部材１３を介して軸芯２１の端部２１ａを支持孔４１に支持させることができる。この場合、外径寸法の異なる複数種の軸部材１３を用意しておき、軸芯２１の外径に合わせて適切な軸部材１３を選択すれば、支持孔４１の内径寸法を軸芯２１に合わせて変更する必要がなくなる。これにより、複数種の軸芯２１に対して支持部材３０の共通化を図ることができる。   6B, the shaft member 13 is inserted into the end portion 21a of the shaft core 21 even when the shaft core 21 of the roll body 20 protrudes from the end surface 22a of the sheet 22. The end 21 a of the shaft core 21 can be supported by the support hole 41 through the shaft member 13. In this case, if a plurality of types of shaft members 13 having different outer diameter dimensions are prepared and an appropriate shaft member 13 is selected according to the outer diameter of the shaft core 21, the inner diameter dimension of the support hole 41 is set to the shaft core 21. There is no need to change it. Thereby, the support member 30 can be shared with respect to the plurality of types of shaft cores 21.

このように構成されるプレート６６は、脚部６２を含むパレット６０の本体部分（樹脂成形体）よりも剛性の高い材料から選択される。例えば、プレート６６の構成材料には、鉄系やアルミニウム系の金属材料を好適に用いることができるが、ガラス繊維や炭素繊維を含む繊維強化樹脂を用いてもよい。   The plate 66 configured in this manner is selected from a material having higher rigidity than the main body portion (resin molded body) of the pallet 60 including the leg portions 62. For example, an iron-based or aluminum-based metal material can be suitably used as the constituent material of the plate 66, but a fiber reinforced resin containing glass fiber or carbon fiber may be used.

（実施形態の作用・効果）
以上、説明した実施形態の作用・効果について述べる。
本実施形態によれば、中空部３２を介して対向する内壁部３１及び外壁部３３を有する中空成形体で支持部材３０を形成したので、搬送用資材１０の軽量化を図ることができる。 (Operation and effect of the embodiment)
The operation and effect of the embodiment described above will be described.
According to the present embodiment, since the support member 30 is formed of the hollow molded body having the inner wall portion 31 and the outer wall portion 33 that face each other via the hollow portion 32, the weight of the transport material 10 can be reduced.

そして、本実施形態では、支持孔４１の直下に補強材４６を設け、支持部材３０の下部を補強した。   In this embodiment, the reinforcing member 46 is provided directly below the support hole 41 to reinforce the lower portion of the support member 30.

これに対し、補強材を設けない場合、ロール体２０の質量によっては、支持孔４１が受ける荷重で支持部材３０の中央下部（中空部３２、内壁部３１、外壁部３３のそれぞれの中央下部）が変形してしまい、必要な支持強度が得られないおそれがある。   On the other hand, when the reinforcing material is not provided, depending on the mass of the roll body 20, the lower center portion of the support member 30 with the load received by the support hole 41 (the lower central portions of the hollow portion 32, the inner wall portion 31, and the outer wall portion 33). May be deformed and the required support strength may not be obtained.

この点、本実施形態では、支持孔４１の直下に補強材４６を設け、支持部材３０の下部を補強したので、支持孔４１に大きな荷重が加わっても、補強材４６によって支持部材３０の中央下部の変形を防止し、支持部材３０の中央下部の剛性を高めることができる。したがって、軽量性に優れ、かつ、高い支持強度が得られる搬送用資材１０を提供することができる。   In this respect, in the present embodiment, the reinforcing material 46 is provided directly below the support hole 41 and the lower portion of the support member 30 is reinforced, so that even if a large load is applied to the support hole 41, Deformation of the lower portion can be prevented, and the rigidity of the lower center portion of the support member 30 can be increased. Therefore, it is possible to provide the transporting material 10 that is excellent in light weight and has high support strength.

また、開口部５３を塞ぐ閉塞材５５を設けたので、閉塞材５５によって中空部３２への水や埃等の異物の侵入を防止できる。これと同時に、挿入された補強材４６と閉塞材５５が嵌合するので、閉塞材５５によって補強材４６を適切な位置に保持・位置決めすることができる。   In addition, since the blocking material 55 that closes the opening 53 is provided, the blocking material 55 can prevent entry of foreign matter such as water and dust into the hollow portion 32. At the same time, since the inserted reinforcing material 46 and the closing material 55 are fitted, the reinforcing material 46 can be held and positioned at an appropriate position by the closing material 55.

また、内壁部３１及び外壁部３３のそれぞれの内面に、補強材４６と接触する接触面（先端面５２）を設けることにより、中空部３２において補強材４６を安定的に保持することができる。   Further, by providing a contact surface (tip surface 52) in contact with the reinforcing material 46 on the inner surface of each of the inner wall portion 31 and the outer wall portion 33, the reinforcing material 46 can be stably held in the hollow portion 32.

また、４本のフレーム部材４７を中空部３２に設けたので、支持部材３０の強度向上及び支持部材３０の形態安定化を図ることができる。これにより、例えば、２個以上の支持部材３０を上下に積んで２本以上のロール体２０を段積みする場合であっても、下段の支持部材３０の変形を抑制でき、２本以上のロール体２０を安定的に搬送・保管することができる。   Further, since the four frame members 47 are provided in the hollow portion 32, the strength of the support member 30 can be improved and the form of the support member 30 can be stabilized. Thereby, for example, even when two or more support members 30 are stacked vertically and two or more roll bodies 20 are stacked, deformation of the lower support member 30 can be suppressed, and two or more rolls The body 20 can be transported and stored stably.

さらに、合成樹脂製のパレット６０において、フォーク差し込み部６３の上方位置に設けたフレーム部材６５により、パレット６０の剛性を高めることができる。これにより、例えば、フォークリフトの荷役に際してパレット６０の端部に荷重が加わっても、パレット６０の変形を抑制することができる。   Further, in the pallet 60 made of synthetic resin, the rigidity of the pallet 60 can be increased by the frame member 65 provided above the fork insertion portion 63. Thereby, for example, even when a load is applied to the end of the pallet 60 when handling a forklift, deformation of the pallet 60 can be suppressed.

加えて、隣り合う２つの脚部６２を跨ぐように設けたプレート６６によって、脚部６２の剛性を高めることができる。これにより、例えば、ロール体２０の保管に際し、脚部６２の変形を抑制することができる。同時に、支持部材３０の下壁部３６をプレート６６の広い上面でしっかりと受けることができる。そして、支持孔４１で受けた荷重を、支持孔４１と地面（脚部６２の下面）との間において、剛性の高い補強材４６、フレーム部材４７，６５及びプレート６６で受けることができる。これにより、支持部材３０の樹脂部分及びパレット６０の樹脂部分に加わる力をより低減でき、支持部材３０及びパレット６０の変形を一層防止することができる。   In addition, the rigidity of the leg portion 62 can be increased by the plate 66 provided so as to straddle the two adjacent leg portions 62. Thereby, for example, when the roll body 20 is stored, the deformation of the leg portion 62 can be suppressed. At the same time, the lower wall portion 36 of the support member 30 can be firmly received by the wide upper surface of the plate 66. The load received by the support hole 41 can be received by the stiff reinforcing material 46, the frame members 47 and 65, and the plate 66 between the support hole 41 and the ground (the lower surface of the leg portion 62). Thereby, the force applied to the resin portion of the support member 30 and the resin portion of the pallet 60 can be further reduced, and the deformation of the support member 30 and the pallet 60 can be further prevented.
