Description

本発明は、帯状ベルト及び無端ベルトに関するものである。   The present invention relates to a belt-like belt and an endless belt.

無端ベルトは、金融端末装置、自動改札機、券売機などの搬送装置における搬送用ベルトに使用されている。この無端ベルトとしては、例えば、繊維材（例えば編布）などの補強材とゴムなどの熱硬化性樹脂とからなるベルトが開示されている（例えば、特許文献１）。   The endless belt is used as a transfer belt in a transfer device such as a financial terminal, an automatic ticket gate, and a ticket vending machine. As this endless belt, for example, a belt formed of a reinforcing material such as a fiber material (for example, knitted fabric) and a thermosetting resin such as rubber is disclosed (for example, Patent Document 1).

特開２０１６−０３８０１０号公報JP, 2016-038010, A

しかしながら上記特許文献１の場合、熱硬化性樹脂を主材料とするので、熱可塑性樹脂同士を接合する接着部が必要であり、作業が煩雑になるという問題がある。搬送装置に使用されている無端ベルトを交換する際、ベルトを交換している間、搬送装置は停止せざるを得ない。そのため、ベルトを交換する作業時間は、可能な限り短いことが望まれる。また、熱可塑性樹脂を融着して無端状とした交換後のベルトは、熱硬化性樹脂で形成されたシームレスベルトに比べ、熱硬化性樹脂と熱可塑性樹脂の境目が早期に劣化し、耐久性が劣ってしまうという懸念がある。   However, in the case of Patent Document 1 described above, since a thermosetting resin is used as a main material, an adhesive part for joining thermoplastic resins is required, and there is a problem that the operation becomes complicated. When replacing the endless belt used in the conveying device, the conveying device must be stopped while replacing the belt. Therefore, it is desirable that the operation time for replacing the belt be as short as possible. In addition, the belt after replacement, in which the thermoplastic resin is fused and made into an endless shape, the boundary between the thermosetting resin and the thermoplastic resin is deteriorated earlier as compared with the seamless belt formed of the thermosetting resin, and the endurance belt is durable. There is a concern that the sex will be inferior.

本発明は、ベルトが使用される現場において容易に接合することができる帯状ベルト、耐久性の低下を抑制することができる無端ベルトを提供することを目的とする。   An object of the present invention is to provide a belt-like belt which can be easily joined at a site where the belt is used, and an endless belt which can suppress the reduction in durability.

本発明に係る帯状ベルトは、熱硬化性樹脂で形成された帯状のベルト本体と、前記ベルト本体の少なくとも一端に設けられた接合部とを備え、前記接合部は、熱可塑性樹脂で形成されている。   The belt-like belt according to the present invention comprises a belt-like belt main body formed of a thermosetting resin, and a joint provided at at least one end of the belt main body, and the joint is formed of a thermoplastic resin There is.

本発明に係る無端ベルトは、熱硬化性樹脂で形成された帯状のベルト本体と、前記ベルト本体の両端部の間に設けられた融着部とを備え、前記融着部は、熱可塑性樹脂で形成され、両端に谷形状の凹部を有し、前記ベルト本体は、両端に前記凹部と相補的な山形状の凸部を有し、前記融着部と前記ベルト本体は、前記凹部と前記凸部において接合されている。   The endless belt according to the present invention comprises a belt-like belt main body formed of a thermosetting resin, and a fusion-bonded portion provided between both ends of the belt main body, and the fusion-bonded portion is a thermoplastic resin The belt main body has a mountain-shaped convex portion complementary to the concave portion at both ends, and the fusion-bonded portion and the belt main body have the concave portion and the concave portion. It joins at a convex part.

本発明によれば、接合部が、予めベルト本体に接合されているため、１ヶ所を接合することにより、無端ベルトを得ることができるので、帯状ベルトは、使用される現場において容易に接続することができる。融着部は、凹部によって厚さ方向の力を幅方向に分散することにより、ベルトの厚さ方向に作用する力による破損を防止し、耐久性の低下を抑制することができる。   According to the present invention, since the joining portion is joined to the belt body in advance, the endless belt can be obtained by joining one place, so that the belt-like belt can be easily connected in the field where it is used be able to. The fusion-bonded portion can prevent the damage due to the force acting in the thickness direction of the belt by dispersing the force in the thickness direction in the width direction by the concave portion, and can suppress the deterioration of the durability.

以下、図面を参照して本発明の実施形態について詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

図１に示す帯状ベルト１０Ａは、ベルト本体１２と、ベルト本体１２の一端である第１端部１３に設けられた第１接合部１４と、他端である第２端部１５に設けられた第２接合部１６とを備える。ベルト本体１２は、熱硬化性樹脂、例えば、ミラブルウレタンやウレタンエラストマーで形成された帯状の部材である。第１端部１３は、長手方向に突出した第１凸部１８を有する。第２端部１５は、長手方向に突出した第２凸部１９を有する。第１凸部１８及び第２凸部１９は、先端に向かって先細となる山形状である。第１凸部１８及び第２凸部１９は、ベルト本体１２の幅方向の中央を頂点とする三角形の２辺で形成されている。第１端部１３及び第２端部１５は、第１凸部１８及び第２凸部１９（山形状）を幅方向において１つのみ有する。第１凸部１８及び第２凸部１９は、ベルト本体１２の第１端部１３及び第２端部１５に対し、打ち抜き加工を施すことにより、形成される。   The belt-like belt 10A shown in FIG. 1 is provided at a belt body 12, a first joint portion 14 provided at a first end 13 which is one end of the belt body 12, and a second end 15 which is the other end. And a second joint portion 16. The belt main body 12 is a belt-like member formed of a thermosetting resin, for example, millable urethane or urethane elastomer. The first end 13 has a first protrusion 18 protruding in the longitudinal direction. The second end 15 has a second protrusion 19 protruding in the longitudinal direction. The first convex portion 18 and the second convex portion 19 have a mountain shape which is tapered toward the tip. The first convex portion 18 and the second convex portion 19 are formed by two sides of a triangle whose apex is the center in the width direction of the belt body 12. The first end 13 and the second end 15 have only one first convex portion 18 and one second convex portion 19 (peak shape) in the width direction. The first convex portion 18 and the second convex portion 19 are formed by punching the first end 13 and the second end 15 of the belt body 12.

第１接合部１４及び第２接合部１６は、熱可塑性樹脂、例えば、ウレタンエラストマー、ポリアミドエラストマー、ポリエステルエラストマー、ポリ塩化ビニル系エラストマー、ポリオレフィン系エラストマーで形成された板状の部材である。第１接合部１４及び第２接合部１６の幅長さは、ベルト本体１２の幅長さと同じである。第１接合部１４は、第１端部１３と接合している側の一端に第１凹部２０、他端に第１平坦部２２を有する。第１凹部２０は、第１凸部１８の山形状に相補的な谷形状を有し、第１凸部１８との間に隙間がない状態で接合されている。第１接合部１４は、第１凹部２０（谷形状）を幅方向に１つのみ有する。第２接合部１６は、第２端部１５と接合している側の一端に第２凹部２１、他端に第２平坦部２３を有する。第２凹部２１は、第２凸部１９の山形状に相補的な谷形状を有し、第２凸部１９との間に隙間がない状態で接合されている。第２接合部１６は、第２凹部２１（谷形状）を幅方向に１つのみ有する。   The first joint portion 14 and the second joint portion 16 are plate-like members formed of a thermoplastic resin, for example, a urethane elastomer, a polyamide elastomer, a polyester elastomer, a polyvinyl chloride elastomer, or a polyolefin elastomer. The width length of the first joint portion 14 and the second joint portion 16 is the same as the width length of the belt body 12. The first joint portion 14 has a first concave portion 20 at one end on the side where it is joined to the first end portion 13 and a first flat portion 22 at the other end. The first concave portion 20 has a valley shape complementary to the mountain shape of the first convex portion 18 and is joined in a state where there is no gap with the first convex portion 18. The 1st junction part 14 has only one 1st crevice 20 (valley shape) in the cross direction. The second joint portion 16 has a second recess 21 at one end on the side where it is joined to the second end 15 and a second flat portion 23 at the other end. The second concave portion 21 has a valley shape complementary to the mountain shape of the second convex portion 19 and is joined to the second convex portion 19 in a state where there is no gap. The 2nd junction part 16 has only one 2nd crevice 21 (valley shape) in the cross direction.

図２を参照して第１接合部１４及び第２接合部１６について説明する。第１接合部１４と第２接合部１６は、向きが異なるのみであるので、代表して第１接合部１４について説明する。第１接合部１４の長さＬ１は、より長い方が、接合する際の作業性を向上することができる。第１接合部１４の長さＬ１は、１０ｍｍ以上であるのがより好ましい。第１凹部２０は、第１接合部１４の幅方向の中央を頂点とする三角形の２辺で形成されている。第１接合部１４は、第１平坦部２２から第１凹部２０の底までの長さＬ２が１ｍｍ以上であるのが好ましい。長さＬ２が１ｍｍ以上であれば、第１平坦部２２と第２平坦部２３の間に隙間がない状態で、第１接合部１４と第２接合部１６を融着することができる。   The first bonding portion 14 and the second bonding portion 16 will be described with reference to FIG. The first bonding portion 14 and the second bonding portion 16 are different only in the direction, so the first bonding portion 14 will be described as a representative. The longer the length L1 of the first bonding portion 14, the more the workability at the time of bonding can be improved. The length L1 of the first bonding portion 14 is more preferably 10 mm or more. The first concave portion 20 is formed by two sides of a triangle whose apex is the center in the width direction of the first joint portion 14. The first bonding portion 14 preferably has a length L2 from the first flat portion 22 to the bottom of the first recess 20 of 1 mm or more. If the length L2 is 1 mm or more, the first bonding portion 14 and the second bonding portion 16 can be fused together with no gap between the first flat portion 22 and the second flat portion 23.

第１凹部２０の２辺のなす角度θは、３０°以上１２０°以下であるのが好ましい。角度θが３０°以上であれば、第１接合部１４と第１端部１３を融着する部分の長手方向の長さが長くなり過ぎない。角度θが１２０°以下であれば、第１接合部１４と第１端部１３の接合面積を十分に確保できる。   The angle θ between two sides of the first recess 20 is preferably 30 ° or more and 120 ° or less. If the angle θ is 30 ° or more, the length in the longitudinal direction of the portion where the first bonding portion 14 and the first end 13 are fused is not too long. If the angle θ is 120 ° or less, the bonding area of the first bonding portion 14 and the first end portion 13 can be sufficiently secured.

次に、本実施形態に係る帯状ベルト１０Ａを無端ベルトにする方法を説明する。まず、第１平坦部２２と第２平坦部２３を突き合わせた状態で、第１端部１３及び第２端部１５を図示しない下型の上面に配置する。第１接合部１４及び第２接合部１６は、第１平坦部２２と第２平坦部２３が接触した状態、又は、厚さ方向に一部が重なった状態で配置される。次いで、第１接合部１４と第２接合部１６の上に上型を配置して、一定時間、加圧体（図示しない）によって厚さ方向に加圧しながら、加熱する。そうすると第１接合部１４と第２接合部１６は、溶融して流動化する。   Next, a method of forming the belt-shaped belt 10A according to the present embodiment as an endless belt will be described. First, in a state where the first flat portion 22 and the second flat portion 23 are in contact with each other, the first end 13 and the second end 15 are disposed on the upper surface of a lower die not shown. The first bonding portion 14 and the second bonding portion 16 are disposed in a state in which the first flat portion 22 and the second flat portion 23 are in contact or in a state in which a part thereof is overlapped in the thickness direction. Next, an upper die is disposed on the first bonding portion 14 and the second bonding portion 16 and heating is performed while pressing in the thickness direction with a pressing body (not shown) for a fixed time. Then, the first joint portion 14 and the second joint portion 16 melt and fluidize.

続いて、下型及び上型を冷却することにより、第１接合部１４及び第２接合部１６が固化し、図３に示すように、融着部２４が形成される。上記のようにして、融着部２４を介して、第１端部１３と第２端部１５が接合され、無端ベルト２５が形成される。   Subsequently, by cooling the lower mold and the upper mold, the first bonding portion 14 and the second bonding portion 16 are solidified, and as shown in FIG. 3, the fusion bonding portion 24 is formed. As described above, the first end 13 and the second end 15 are joined via the fusion-bonded portion 24 to form the endless belt 25.

本実施形態の場合、第１接合部１４及び第２接合部１６が、予めベルト本体１２に接合されているため、第１接合部１４及び第２接合部１６同士の１ヶ所を接合することにより、無端ベルト２５を得ることができる。したがって接合箇所を１ヶ所のみとすることができるので、帯状ベルト１０Ａは、使用される現場において容易に接続することができる。   In the case of the present embodiment, since the first bonding portion 14 and the second bonding portion 16 are bonded in advance to the belt body 12, the first bonding portion 14 and the second bonding portion 16 are joined together at one place. , Endless belt 25 can be obtained. Therefore, since the joining point can be made only at one place, the belt-like belt 10A can be easily connected at the site where it is used.

熱可塑性樹脂は、熱硬化性樹脂に比べ、硬度が高くなる。したがって融着部２４と、第１端部１３及び第２端部１５の間は、ベルト本体１２に比べ、厚さ方向の力に対する強度が低下する。本実施形態の場合、融着部２４は、第１凹部２０及び第２凹部２１によって厚さ方向の力を幅方向に分散する。したがって本実施形態の無端ベルトは、ベルトの厚さ方向に作用する力による破損を防止し、耐久性の低下を抑制することができる。   Thermoplastic resins have higher hardness than thermosetting resins. Therefore, the strength against the force in the thickness direction is reduced between the fusion-bonded portion 24 and the first end 13 and the second end 15 compared to the belt body 12. In the case of the present embodiment, the fusion bonded portion 24 disperses the force in the thickness direction in the width direction by the first recess 20 and the second recess 21. Therefore, the endless belt of the present embodiment can prevent damage due to a force acting in the thickness direction of the belt, and can suppress deterioration in durability.

（変形例）
本発明は上記実施形態に限定されるものではなく、本発明の趣旨の範囲内で適宜変更することが可能である。 (Modification)
The present invention is not limited to the above embodiment, and can be appropriately modified within the scope of the present invention.

上記実施形態の場合、帯状ベルト１０Ａは、第１接合部１４及び第２接合部１６を備える場合について説明したが、本発明はこれに限らない。例えば、図４に示すように、帯状ベルト１０Ｂは、１つの接合部２６のみを備えることとしてもよい。本図に示す帯状ベルト１０Ｂは、ベルト本体１２と、第２端部１５に設けられた接合部２６を備える。第１端部１３は、第１凸部１８を有するのみで、接合部は設けられていない。接合部２６は、一端に第１凹部２０、他端に第２凹部２１を有する。第２凹部２１は第２凸部１９に接合されている。帯状ベルト１０Ｂは、第１凹部２０と第１凸部１８の１ヶ所を接合することにより、第１端部１３と第２端部１５を接合することができる。接合部２６は、第１凹部２０及び第２凹部２１を有するので、上記第１実施形態と同様の効果を得ることができる。   In the case of the said embodiment, although the strip | belt-shaped belt 10A demonstrated the case where the 1st junction part 14 and the 2nd junction part 16 were provided, this invention is not limited to this. For example, as shown in FIG. 4, the belt-like belt 10 </ b> B may include only one joint portion 26. The belt-like belt 10 </ b> B shown in this figure includes a belt body 12 and a joint 26 provided at the second end 15. The first end portion 13 only has the first convex portion 18 and no joint portion is provided. The joint portion 26 has a first recess 20 at one end and a second recess 21 at the other end. The second recess 21 is joined to the second protrusion 19. The belt-like belt 10B can join the first end 13 and the second end 15 by joining the first recess 20 and one point of the first projection 18. The joint portion 26 has the first concave portion 20 and the second concave portion 21. Therefore, the same effect as that of the first embodiment can be obtained.

上記実施形態の場合、第１接合部１４と第２接合部１６は、向きが異なるのみでその他は同じである場合について説明したが、本発明はこれに限らない。例えば、図５に示す帯状ベルト１０Ｃは、ベルト本体１２と、第１端部１３に設けられた第１接合部１４と、第２端部１５に設けられ、第１接合部１４より長手方向の長さが長い第２接合部２８とを備える。第２接合部２８の長さは、少なくともベルト本体１２の長さの１０％以上が好ましい。第２接合部２８が上記の長さを有することにより、ベルトを設置する機械に合わせて無端ベルトの長さを適宜調整することができる。したがって帯状ベルト１０Ｃは、汎用性を向上することができる。   In the case of the above-mentioned embodiment, although the case where the 1st joined part 14 and the 2nd joined part 16 differ only in direction, and others are the same was explained, the present invention is not limited to this. For example, the belt-like belt 10C shown in FIG. 5 is provided at the belt body 12, the first joint portion 14 provided at the first end portion 13, and the second end portion 15, and the longitudinal direction from the first joint portion 14 And a second joint 28 having a long length. The length of the second joint portion 28 is preferably at least 10% or more of the length of the belt body 12. When the second joint portion 28 has the above length, the length of the endless belt can be appropriately adjusted in accordance with the machine in which the belt is installed. Therefore, belt-like belt 10C can improve versatility.

上記実施形態の場合、第１凹部２０（第２凹部２１）は、第１接合部１４（第２接合部１６）の幅方向の中央を頂点とする三角形の２辺で形成されている場合について説明したが、本発明はこれに限らない。例えば、図６Ａに示すように、第１凹部（第２凹部）３４は、第１接合部（第２接合部）３２の幅方向の一方に偏った位置を頂点とする三角形の２辺で形成してもよい。図６Ｂに示すように、第１接合部（第２接合部）３３は、第１凹部（第２凹部）３５の谷形状を形成する三角形の２辺とベルト本体の側辺との接点が、ベルト本体の長さ方向にずれていてもよい。   In the case of the above embodiment, the case where the first recess 20 (the second recess 21) is formed by two sides of a triangle having the center in the width direction of the first bonding portion 14 (the second bonding portion 16) as a vertex Although described, the present invention is not limited thereto. For example, as shown to FIG. 6A, the 1st recessed part (2nd recessed part) 34 is formed by two sides of the triangle which makes a position deviated to one side of the width direction of the 1st junction part (2nd junction part) 32 a vertex. You may As shown in FIG. 6B, in the first joint portion (second joint portion) 33, the contact point between the two sides of the triangle forming the valley shape of the first recess (second recess) 35 and the side edge of the belt body is It may be offset in the length direction of the belt body.
