コンベヤベルト無端化のための接合方式として、加硫ジョイント方式と金具ジ ョイント方式がよく知られている。 このうち加硫ジョイント方式として、ベルト接合用両端部にそれぞれ上下相対 応してステップ形状を形成し、これら両ステップ状両端部を広域的に面接状に重 ね合せて接着または加硫一体化するオーバーラップ方式、およびベルト接合用両 端部にそれぞれ上下相対応してステップ形状を形成し、これら両ステップ状両先 端部を互いに突き合わせて接着または加硫一体化する突き合せ方式がある。 As a joining method for endless conveyor belts, vulcanization joint method and metal fittings The joint method is well known. Of these, the vulcanized joint method is that the belt joining ends are vertically In response, a step shape is formed, and both ends of these step shapes are overlapped in a wide area in an interview shape. Overlap method for unifying and bonding or vulcanizing, and both for belt joining Step shapes are formed corresponding to the upper and lower phases at the ends, respectively There is a butting method in which the ends are butted against each other and bonded or vulcanized together.
【0003】 上記オーバーラップ方式,突き合せ方式ともに、ベルトの芯体を構成する帆布 の接合部において、具体的にオーバーラップ方式にては芯体接合部の重ね合せ両 端部、また突き合せ方式にては芯体先端部の突き合わせ両先端部にて多発する起 き上り現象あるいは割れ現象の発生を防止するために、該ベルト両端接合部の芯 体帆布面に、縦,横糸が共にナイロン,ポリエステル,綿,ビニロンなどをもっ て織製された平織補強帆布を貼着して該接合部を補強する手段が採用されている 。[0003] Both the overlap method and the butt method, the canvas that forms the core of the belt At the joint part of the core, specifically, the overlap method In the end part, or in the butt method, the occurrence of frequent occurrences at both ends of the butt of the core body In order to prevent the rise phenomenon or cracking phenomenon, The warp and weft threads are made of nylon, polyester, cotton, vinylon, etc. on the body canvas surface. A means for adhering a plain weave reinforced canvas that is woven to reinforce the joint is adopted. .
【0004】[0004]
上記、平織帆布を用いてのベルト接合部の補強にあっては、ベルトを掛巻する プーリ径が小さい場合、当然ベルトの屈曲半径が小さくなり、それに伴いベルト 自体の伸張が大きくなるが、ベルト接合部に貼着使用されているナイロン,綿な どの平織補強帆布自体の伸びはベルトの伸張に十分追随することができず、肝心 な補強帆布に割れが生じ、芯体帆布接合部の先端に起き上り現象が発生し、ベル ト接合部を弱体化しめ、所期の目的を十分達成することができないなどの問題点 が依然として残されている。 For reinforcing the belt joint using the plain weave canvas, wind the belt. When the pulley diameter is small, the bending radius of the belt naturally becomes smaller, and the belt Although it stretches a lot, it does not use nylon or cotton that is attached to the belt joint. The stretch of any plain weave reinforced canvas itself cannot keep up with the stretch of the belt. Cracks occur in the reinforced canvas and the rising phenomenon occurs at the tip of the joint between the core and the canvas. Problems such as weakening the joints and failing to achieve the intended purpose Is still left.
【0005】 この考案は補強帆布自体にベルトの伸張に十分順応することができる伸縮性と 屈曲性を保有する帆布を用い、かつ補強帆布自体の伸長力を十分発揮せしめ得る ようベルトの芯体帆布の両端接合部にて形成されるエンドレス角度方向を考慮し た貼着角度の選択により、従来の平織補強帆布を十分凌駕しうる補強効果を発揮 しうるコンベヤベルト接合部の補強構造を提供することを目的とする。[0005] The idea is that the reinforced canvas itself is elastic enough to adapt to the stretching of the belt. Uses a canvas that has flexibility and allows the reinforcing canvas itself to exert its full extension force. Considering the endless angle direction formed at both ends of the belt core canvas By selecting the sticking angle, the reinforcement effect that can sufficiently surpass the conventional plain weave reinforced canvas is exhibited. It is an object of the present invention to provide a reinforcement structure for a conveyor belt joint which can be formed.

上記目的を達成するために、この考案に係るコンベヤベルト接合部の構造は以 下のとおりである。 芯体帆布の少なくとも片面に、ゴムまたは合成樹脂製の弾性体層を積層してな るコンベヤベルトにあって、ベルトの無端化のための両端部に位置する帆布の接 合部に、通常糸からなる縦糸と弾性糸単独または少なくともその一部に弾性糸を 用いてなる横糸をもって織製した綾織または朱子織からなる斜織目を有する伸縮 性補強帆布をして、その織目方向を芯体帆布の両端接合部に形成されるベルトエ ンドレス角度に同一角度をも含めて、略近付けて貼着したことを特徴とする。 そしてこの補強帆布は全芯体帆布の接合部に対して、あるいは芯体帆布の一部 の場合もあり、特にベルト面に露出する芯体帆布の接合部に貼着される補強帆布 の隅角先端が直角または鋭角を呈している折には、該部にカット代を設けたこと を特徴とする。 In order to achieve the above object, the structure of the conveyor belt joint according to the present invention is as follows. It is as below. A rubber or synthetic resin elastic layer must be laminated on at least one side of the core canvas. Of the conveyor belt that is located at both ends for endless belt At the joint, warp yarn consisting of normal yarn and elastic yarn alone or at least a part of elastic yarn Stretching with twill weave or satin weave woven with the weft threads used A fabric with a fabric reinforcement, and the weave direction of the belt is formed at the joints at both ends of the core canvas. It is characterized in that they are attached close to each other, including the same angle as the endless angle. And this reinforcing canvas is used for the joints of all-core canvas or a part of core-can canvas. In some cases, especially the reinforcing canvas attached to the joint part of the core canvas exposed on the belt surface. If the tip of the corner of the corner has a right angle or an acute angle, a cutting allowance shall be provided on that part. Is characterized by.

Consists of a laminate of canvas (3), intermediate rubber layer (4) and bottom canvas (5) on the bottom surface As shown in FIG. 3, the joining right end of the belt has an upper cover rubber layer (2). From the embedded core canvas (3) and the intermediate rubber layer (4) from the bottom canvas (5), respectively. It is removed and has a step shape. On the other hand, the left end of the belt joint is in the opposite direction to that of FIG. Adhesive is applied to the end joints, and embedded core canvas (3) (3) And the bottom canvas (5) (5) comrades are stuck together in an overlap shape, and on the bottom of the belt. The twill weave or satin weave on the overlap joint of the bottom canvas (5) Reinforcing canvas (7) having a diagonal weave and being highly elastic and flexible, Bell whose weave (a) is limited to the range of 0 ° to 60 ° of the joint end (6) of the core canvas Bond the endless angles, including the same angle, with a near-normal temperature adhesive and approximately To be done.
【0009】 なお、図4は他の実施例を示し、図1に示す同じくオーバーラップされた埋設 芯体帆布(3)(3)の接合部にも綾織または朱子織からなる斜織目を有する伸 縮性補強帆布(7)を、同じくその斜織目(イ)を0°〜60°の範囲に限定さ れた芯体帆布の接合部(6)のベルトエンドレス角度に同一角度をも含めて、略 近付けて貼着する構成を採用し、ベルト接合部をさらに補強強化することも可能 である。ただし、本実施例にあっては、伸縮性補強帆布(7)はRFL処理を施 した後、予めゴムで糊付け(コーチング処理)したものを用い、ゴム層(2)( 4)との接着強度を確保することが必要である。[0009] Note that FIG. 4 shows another embodiment, in which the same overlapping buried structure shown in FIG. At the joint of the core canvas (3) (3) as well, there is a stretched weave having twill or satin weave. The shrinkable reinforcing canvas (7) is also limited to the diagonal weave (a) within the range of 0 ° to 60 °. Including the same angle in the belt endless angle of the joint part (6) of the core canvas Adopting a structure in which they are attached close to each other, it is possible to further strengthen and strengthen the belt joint Is. However, in this example, the stretchable reinforcing canvas (7) was subjected to RFL treatment. After that, using the one that has been glued (coated) with rubber in advance, the rubber layer (2) ( It is necessary to secure the adhesive strength with 4).
