Description
本発明は、製造ラインや物流機構における物品の搬送工程に用いる搬送用ベルトに関する。 The present invention relates to a conveyor belt used in an article conveyance process in a production line or a physical distribution mechanism.
各種物品の製造ラインにおける、製造途中の中間体や完成した物品の搬送、及び宅配便の搬送センター等物流機構における物品の搬送には、一般にベルトコンベヤが広く用いられている。このベルトコンベヤは、通常、織物や不織布といった布帛、ゴムシート、合成樹脂シート、或いはこれらの複合体からなる帯体の両端を相互に連結することでループ形状とした搬送用ベルトを複数のロールに掛け渡して回転させ、該搬送用ベルトに搬送すべき物品を載せ、或いは、該搬送用ベルトと該ベルトの掛け渡し経路に配置した対向部材との隙間に物品を挟持して該物品を搬送する。 Generally, belt conveyors are widely used for transporting intermediates and finished products in the production line of various products, and transporting products in a physical distribution mechanism such as a courier transport center. In this belt conveyor, a conveyor belt having a loop shape is usually formed on a plurality of rolls by connecting both ends of a fabric made of woven fabric or nonwoven fabric, a rubber sheet, a synthetic resin sheet, or a band made of a composite thereof. The article to be conveyed is placed on the conveyor belt and rotated, or the article is conveyed by holding the article in a gap between the conveyor belt and an opposing member disposed in the belt path. .
このような搬送用ベルトとしては、要求される特性に応じて、多様な素材、構成が提案されている。 As such a conveyor belt, various materials and configurations have been proposed according to required characteristics.
例えば、特許文献１には、段ボールシートの製造に用いられる、いわゆるコルゲーターベルトとして、綿繊維を中心にその周囲にポリエステル繊維を配置した構成糸を用いて多重織り組織を形成し、耐熱性と吸湿性を付与した構成が開示されている。 For example, in Patent Document 1, as a so-called corrugator belt used in the manufacture of a corrugated cardboard sheet, a multi-woven structure is formed by using a constituent yarn in which polyester fibers are arranged around a cotton fiber, and heat resistance and moisture absorption. The structure which gave the property is disclosed.
また、特許文献２には、多重織り組織を有する織物ベルトにおいて、表面層の経糸を、幅方向両端部（縁部）は芳香族系ポリアミド繊維で、中央部はポリエステルとビスコースとの混合物からなる繊維で形成することで、該両端部に耐熱性及び耐摩耗性を付与した構成が開示されている。 Further, in Patent Document 2, in a woven belt having a multi-woven structure, the warp of the surface layer, the width direction both ends (edges) are aromatic polyamide fibers, and the center is made of a mixture of polyester and viscose. A structure in which heat resistance and wear resistance are imparted to the both end portions by forming the fiber is disclosed.
コルゲーターベルトは、接着剤を塗布した片面段ボール紙とライナー紙とが良好に貼り合わされるように、ベルトの裏面側より加圧部材で加圧して、貼り合わせ後の段ボールシートを適度に加圧している。一方で、段ボールシートの製造効率を高めるため、コルゲーターにおいて段ボールシートを搬送するコルゲーターベルトの回転速度はより高速化している。そのため、移動方向に所定の長さを有する板状の加圧部材を強くベルトに接触させる必要があり、加圧部材との摩擦によって、ベルトの裏面が従来にない高温に達し、摩耗してベルトが短寿命化するという問題が発生している。 The corrugator belt is pressed with a pressure member from the back side of the belt so that the single-sided corrugated paper coated with adhesive and the liner paper are well bonded, and the corrugated cardboard sheet is pressed appropriately. Yes. On the other hand, in order to increase the manufacturing efficiency of the corrugated cardboard sheet, the corrugator belt that transports the corrugated cardboard sheet in the corrugator has a higher rotational speed. Therefore, it is necessary to bring a plate-like pressure member having a predetermined length in the moving direction into strong contact with the belt, and due to friction with the pressure member, the back surface of the belt reaches an unprecedented high temperature and wears. Has a problem of shortening the service life.
本発明の課題は、上記のようなベルトの過熱による劣化問題に鑑み、放熱性及び放湿性に優れ、耐久性の高い搬送用ベルトを提供することにある。 An object of the present invention is to provide a transport belt that is excellent in heat dissipation and moisture release properties and has high durability in view of the above-described degradation problem due to overheating of the belt.
本発明の第１は、段ボールシート製造用のコルゲーターベルトとして用いられる搬送用ベルトであって、少なくとも織り組織を２層以上有する多重織り組織からなる搬送用ベルトであって、少なくとも一方の表面において、最外層の織り組織を構成する経糸を部分的に抜くことでベルトの幅方向において凹凸が形成されていることを特徴とする。 The first invention is a conveyor belt used as a corrugator belt for cardboard-sheet manufacturing, a conveyor belt consisting of multiple weave having at least weave two or more layers, at least one surface, Unevenness is formed in the width direction of the belt by partially removing the warp constituting the outermost woven structure .
本発明の第２は、段ボールシート製造用のコルゲーターベルトとして用いられる搬送用ベルトであって、少なくとも織り組織を２層以上有する多重織り組織からなる搬送用ベルトであって、少なくとも一方の表面において、最外層の織り組織を構成する経糸の太さを部分的に変えることでベルトの幅方向において凹凸が形成されていることを特徴とする。 A second aspect of the present invention is a conveyor belt used as a corrugator belt for producing corrugated cardboard sheets , and is a conveyor belt having a multi-woven structure having at least two layers of woven structure, and at least on one surface, Unevenness is formed in the width direction of the belt by partially changing the thickness of the warp constituting the woven structure of the outermost layer.
また本発明において上記凹凸がベルトの表側に形成されており、凸部の頂部或いは凹部がポリ酢酸ビニル発泡体もしくはシリコーンゴムで被覆されていることが好ましい。 In the present invention, it is preferable that the unevenness is formed on the front side of the belt, and the top or the recess of the convex portion is covered with a polyvinyl acetate foam or silicone rubber.
さらにまた、本発明において上記凹凸がベルトの表側に形成されており、凸部を構成する経糸がポリ酢酸ビニル発泡体もしくはシリコーンゴムで被覆されていることが好ましい。 Furthermore, in the present invention, it is preferable that the unevenness is formed on the front side of the belt, and the warp constituting the convex portion is covered with a polyvinyl acetate foam or silicone rubber.
本発明においては、表面に凹凸を設けることによって実質的に表面積が高くなることから、放熱性及び放湿性に優れ、ベルトの過熱が抑制されて該過熱による劣化が防止され、また、被搬送物品に由来する湿気も良好に放湿される。また、該凹凸を利用して樹脂等を部分的に被覆して、放熱性や放湿性を損ねることなく滑り止め作用を付すことができ、ベルトの空回りや被搬送物品の空送りを防止することができる。 In the present invention, since the surface area is substantially increased by providing irregularities on the surface, heat dissipation and moisture release are excellent, belt overheating is suppressed, and deterioration due to the overheating is prevented. The moisture derived from is also released well. In addition, the resin can be partially covered by using the unevenness to provide a non-slip action without impairing heat dissipation and moisture release, and to prevent the belt from spinning around and the articles to be transported from being idle. Can do.
本発明の搬送用ベルトは、基本構成として多重織り組織を有している。本発明にかかる多重織り組織は、表面層と裏面層との少なくとも２層を必須とし、必要に応じてこれらの間に１層以上の中間層を有し、各層がそれぞれ経糸と緯糸とで織られ、さらに、各層同士は長さ方向に織り込まれた連結糸によって一体化されている。 The conveying belt of the present invention has a multi-woven structure as a basic configuration. The multi-woven structure according to the present invention has at least two layers of a front surface layer and a back surface layer, and has one or more intermediate layers between them as necessary. Each layer is woven with warp and weft yarns, respectively. Further, the layers are integrated with each other by connecting yarns woven in the length direction.
図１、図２に本発明に好ましく適用される多重織り組織の構成を示す。これらの図は、ベルトの長さ方向の断面において、必要最小限の構成を示している。図中、１０は表面層、２０は中間層、３０は裏面層、１１、２１、３１は緯糸、１２ａ〜１２ｄ、２２ａ、２２ｂ、３２ａ〜３２ｄは経糸、４１ａ、４１ｂ、４２ａ、４２ｂは連結糸である。 1 and 2 show the structure of a multi-woven structure preferably applied to the present invention. These drawings show the minimum necessary configuration in the longitudinal section of the belt. In the figure, 10 is a surface layer, 20 is an intermediate layer, 30 is a back layer, 11, 21 and 31 are wefts, 12a to 12d, 22a, 22b and 32a to 32d are warps, 41a, 41b, 42a and 42b are connecting yarns It is.
本発明の搬送用ベルトの特徴は、表面及び／または裏面が、ベルトの幅方向断面において凹凸を有することにある。具体的には、表面層及び／または裏面層において経糸の太さを部分的に変える、或いは経糸を部分的に抜くことで幅方向に厚みの異なる部位を形成する。このように表面に凹凸を付すことにより、ベルトの表面積が大きくなり、放熱性が向上し、加圧部材や被搬送物品等との摩擦熱を効率よく放熱し、ベルト自身の過熱を防止することができる。また、表面積が広がったことで、被搬送物品に由来する湿気も良好に放湿することができる。 A feature of the conveying belt of the present invention is that the front surface and / or the back surface has irregularities in the cross section in the width direction of the belt. Specifically, a part having a different thickness in the width direction is formed by partially changing the thickness of the warp in the surface layer and / or the back layer, or by partially removing the warp. By providing irregularities on the surface in this way, the surface area of the belt is increased, heat dissipation is improved, frictional heat with the pressure member and the article to be transported is efficiently radiated, and overheating of the belt itself is prevented. Can do. Further, since the surface area is widened, moisture derived from the article to be conveyed can be well released.
本発明にかかる凹凸は、特に周期的に形成する必要はなく、放熱効率とベルトの強度とのバランスを見て適宜設定すればよい。即ち、凹部においては凸部よりも細い経糸が用いられているか、或いは、経糸が抜かれているため、そのままでは凸部よりも弱く、層全体の強度も凹凸を形成したことで低下する。従って、凹凸は強度を損ねないように形成することが望ましく、特に、ベルトの幅方向端部（いわゆる耳部）においては、中央部よりも強度が低いため、中央部よりも凹部の数を減らす（或いは形成しない）、凹部の深さを小さくする、凹部の幅を狭くする、或いは、凹部を構成する経糸に強度の高い素材を用いる、などの配慮を施すことが望ましい。 The unevenness according to the present invention does not need to be formed periodically, and may be appropriately set in view of the balance between the heat radiation efficiency and the belt strength. That is, a warp that is thinner than the convex part is used in the concave part, or the warp is pulled out, so that it is weaker than the convex part as it is, and the strength of the entire layer is reduced by forming the concaves and convexes. Accordingly, it is desirable to form the irregularities so as not to impair the strength. In particular, since the strength is lower at the end portion in the width direction of the belt (so-called ear portion) than at the central portion, the number of concave portions is reduced as compared with the central portion. It is desirable to take into consideration such as (or not forming), reducing the depth of the recess, reducing the width of the recess, or using a high-strength material for the warp forming the recess.
また、本発明にかかる凹凸を利用して、ベルトの放熱性や放湿性を損なうことなく被搬送物品の滑り止め作用を付与することができる。具体的には、かかる凹凸をベルトの表側に形成し、凸部或いは凹部のいずれかに摩擦係数の高い樹脂被覆を施す。被覆樹脂としてはポリ酢酸ビニル発泡体もしくはシリコーンゴムが好ましく用いられる。また、当該樹脂被覆を施した経糸で凸部を構成することにより同様の効果が得られる。尚、当該樹脂被服は凸部或いは凹部全面に形成してもよいが、高い放熱性や放湿性を得る上で、凸部或いは凹部に所定の間隔をおいてドット状に形成することが好ましい。 Moreover, the unevenness | corrugation concerning this invention can be utilized, and the anti-slip | skid effect | action of a to-be-conveyed article can be provided, without impairing the heat dissipation and moisture release property of a belt. Specifically, such unevenness is formed on the front side of the belt, and either a convex portion or a concave portion is coated with a resin coating having a high friction coefficient. Polyvinyl acetate foam or silicone rubber is preferably used as the coating resin. Moreover, the same effect is acquired by comprising a convex part with the warp which gave the said resin coating. In addition, although the said resin clothing may be formed in a convex part or the whole recessed part surface, in order to obtain high heat dissipation and moisture release, it is preferable to form in a dot form at predetermined intervals in a convex part or a recessed part.
本発明において多重織り組織を構成する経糸、緯糸、及び連結糸としては、通常の搬送用ベルトに用いられているポリエステル糸、綿糸、レーヨン糸、或いは、ポリエステル、綿、レーヨンの少なくとも一種を含む混紡糸が好ましく用いられる。また、耐熱性ポリエステル、特にポリアニリレートやポリパラフェニレンベンゾビスオキサゾール（ＰＢＯ）、芳香族ポリアミドからなる糸、或いは、これらのうちの少なくとも一種を含む混紡糸が耐熱性や耐摩耗性の点から好ましく用いられる。また、これらは、モノフィラメント、マルチフィラメントのいずれであってもかまわない。 In the present invention, the warp yarn, the weft yarn, and the connecting yarn constituting the multi-weave structure are polyester yarn, cotton yarn, rayon yarn, or a blend containing at least one of polyester, cotton, rayon, which is used for a normal conveying belt. Yarn is preferably used. In addition, a heat-resistant polyester, in particular, a polyanilate, polyparaphenylenebenzobisoxazole (PBO), a yarn made of an aromatic polyamide, or a mixed yarn containing at least one of these is preferable from the viewpoint of heat resistance and wear resistance. Used. These may be monofilaments or multifilaments.
本発明は、ベルトの過熱や水性接着剤に起因する湿気が問題となっているコルゲーターベルトに好ましく適用されるが、特にこれに限定されるものではなく、段ボール製造以外の分野のいずれにおいても好ましく用いられるものである。 The present invention is preferably applied to a corrugator belt in which moisture due to overheating of the belt or an aqueous adhesive is a problem. However, the present invention is not particularly limited to this and is preferable in any field other than corrugated cardboard manufacturing. It is used.
