Description

この発明は、コンベアベルト、なかでも、急傾斜コンベアとして用いて好適なコンベアベルトに関するものであり、とくには、粉・粒状物、塊状物等を搬送するに当って、水分を含むそれらの被搬送物が、コンベアベルトの波形桟、横桟等に付着するのを防止し、および／または、それらの桟が、コンベアベルト上へ落下供給される被搬送物、および、コンベアベルトの、所定の経路上での走行を担保するローラやディスクプーリ等によって早期に摩耗されるのを防止する技術を提案するものである。   The present invention relates to a conveyor belt, and more particularly to a conveyor belt suitable for use as a steeply inclined conveyor, and in particular, when conveying powder, granular material, lump, etc., those to be conveyed containing moisture. The object is prevented from adhering to the corrugated beam, the horizontal beam, etc. of the conveyor belt, and / or the object to be conveyed and supplied to the conveyor belt by dropping, and the predetermined path of the conveyor belt. The present invention proposes a technique for preventing early wear by a roller, a disk pulley, or the like that ensures the above traveling.

たとえば、急傾斜コンベアとして用いられる、波形桟および横桟を具えるコンベアベルトにおいて、横桟表面への運搬物の付着を防止する従来技術としては、特許文献１に記載されているように、横桟の前後表面に、分子量が１００万以上の高分子量ポリエチレンシートを一体的に貼付けて構成するものがあり、これによれば、付着性の強い運搬物であっても、横桟表面に熱融着させた高分子量ポリエチレンシートにより、横桟表面への運搬物の付着を有効に防止できるとする。   For example, in a conveyor belt having corrugated bars and horizontal rails used as steeply inclined conveyors, as described in Patent Document 1, as a conventional technique for preventing adhesion of a transported material to the horizontal rail surface, There are some which are made by integrally pasting high molecular weight polyethylene sheets with a molecular weight of 1 million or more on the front and back surfaces of the crosspieces. Assume that the attached high molecular weight polyethylene sheet can effectively prevent the transported material from adhering to the surface of the crosspiece.

また、特許文献２には、急傾斜コンベアとして用いることができるコンベアベルトにあって、立設された波桟および横桟の頂部を、シュートからの積載物の落下による摩耗および、ベルト変角部のディスクローラあるいはリターンローラとの接触による摩耗から保護するべく、波桟および横桟の頂部を、セラミックチップの接着によって被覆する技術が開示されている。
特開平７−１７９２１１号公報 実開昭６０−１０３１１５号公報 Further, Patent Document 2 discloses a conveyor belt that can be used as a steeply inclined conveyor. In order to protect against wear caused by contact with the disk roller or return roller, a technique for covering the tops of the wave beam and the horizontal beam by bonding a ceramic chip is disclosed.
JP-A-7-179211 Japanese Utility Model Publication No. 60-103115

しかるに、高分子量ポリエチレンシートを横桟に張付ける、特許文献１に記載された技術では、運搬物が、硬質にして鋭利は角部を有するものである場合等に、ポリエチレンシートが破損され易い他、運搬物との擦れによって、ポリエチレンシートに早期の剥れ、摩滅等が生じ易いという問題があり、また、桟の頂部をセラミックチップで被覆する、特許文献２に記載された技術によれば、コンベアベルトを、駆動および従動プーリ等に巻き掛けるに当っての波桟の伸縮変形に対する、セラミックチップの追従性の低さに由来するセラミックチップの剥離・脱落が否めず、また、波桟の伸長変形下ではチップ間隔が大きくなるため、セラミックチップの間隔部分がローラと接触して早期に摩耗されるおそれがある等の問題があった。   However, in the technique described in Patent Document 1 in which a high-molecular-weight polyethylene sheet is attached to a horizontal rail, the polyethylene sheet is easily damaged when the transported object is hard and has sharp edges. In addition, there is a problem that the polyethylene sheet is likely to be prematurely peeled off or worn away due to rubbing with the transported material, and the top portion of the crosspiece is covered with a ceramic chip. According to the technique described in Patent Document 2, The ceramic chip can not be peeled or dropped due to the low followability of the ceramic chip against the stretching deformation of the wave bridge when the conveyor belt is wound around the drive and driven pulleys, etc. Since the chip interval becomes large under deformation, there is a problem that the interval portion of the ceramic chip may come into contact with the roller and be worn at an early stage.

この発明は、従来技術が抱えるこのような問題点を解決することを課題とするものであり、それの目的とするところは、波形桟、横桟への被搬送物の付着、および、それらの桟の摩耗の少なくとも一方を、別添部材の破損、摩滅、脱落等のおそれとは全く無関係に、長期間にわたって確実に、かつ効果的に防止できるコンベアベルトを提供するにある。   An object of the present invention is to solve such problems of the prior art, and the object of the invention is to attach the object to be conveyed to the corrugated beam, the horizontal beam, and those It is an object of the present invention to provide a conveyor belt that can reliably and effectively prevent at least one of the wear of the crosspieces over a long period of time regardless of the possibility of damage, abrasion, or dropping of the attachment member.

この発明に係るコンベアベルトは、無端状の平坦なベースベルトと、ベースベルトの両側部に立設されてベースベルトの延在方向に延びる波形桟と、これらの一対の波形桟間で、ベースベルトの延在方向に所定の間隔をおいて立設されてベースベルトの幅方向に延びる横桟とを具えるものであって、波形桟および横桟の少なくとも一方を、それの厚み方向に、加硫、接着剤等をもって接合された二種類以上のゴムによって構成してなるにある。   A conveyor belt according to the present invention includes an endless flat base belt, a corrugated bar that is provided on both sides of the base belt and extends in the extending direction of the base belt, and a base belt between the pair of corrugated bars. And a horizontal beam extending in the width direction of the base belt and extending at least one of the corrugated beam and the horizontal beam in the thickness direction thereof. It consists of two or more types of rubber joined together with sulfur, adhesive, and the like.

この場合、より好ましくは、波形桟および横桟の少なくとも一方の、被搬送物との接触表面側部分を撥水性のゴムにより、そして、その表面側部分とは反対側の表面部分を耐摩耗性のゴムによりそれぞれ構成する。   In this case, more preferably, at least one of the corrugated beam and the horizontal beam is made of water-repellent rubber on the contact surface side portion with the conveyed object, and the surface portion opposite to the surface side portion is wear-resistant. Each rubber is made up of.

また好ましくは、二種類以上のいずれかの種類のゴムも天然ゴムを共通成分としてなるものとする。   Preferably, any of the two or more types of rubber is made of natural rubber as a common component.

そしてまた、このようなコンベアベルトでは、波形桟および横桟の少なくとも一方に、たとえば、帆布等からなる織布補強層を埋設すること、波形桟および横桟の少なくとも一方の頂部を耐摩耗性のゴムで覆うことが好ましい。   Moreover, in such a conveyor belt, for example, a woven fabric reinforcing layer made of canvas or the like is embedded in at least one of the corrugated rail and the horizontal rail, and the top portion of at least one of the corrugated rail and the horizontal rail is wear-resistant. It is preferable to cover with rubber.

この発明に係るコンベアベルトでは、とくに、波形桟および横桟の少なくとも一方を、それの厚み方向に接合された二種類以上のゴムの積層体にて構成することで、桟の所要部分を所要に応じた物性をもつゴム種によって形成することができ、その桟の、被搬送物との接触表面側部分のゴム種を相対的に撥水性の高いものとすることで、水分を含む被搬送物の、その桟への付着を、その撥水製ゴムが摩滅等するまでの間、長期間にわたって有効に防止することができる。   In the conveyor belt according to the present invention, in particular, at least one of the corrugated beam and the horizontal beam is constituted by a laminated body of two or more kinds of rubbers joined in the thickness direction thereof, so that a required portion of the beam is required. It can be formed by rubber types with appropriate physical properties, and by making the rubber type of the side of the cross-contact surface with the object to be conveyed relatively water-repellent, the object to be conveyed containing moisture Can be effectively prevented over a long period of time until the water-repellent rubber is worn away.

この一方で、桟の、被搬送物との接触表面側部分とは反対側の、ローラやディスクプーリ、落下供給被搬送物との接触表面部分を、他のゴム種に比して、相対的に耐摩耗性にすぐれたゴム種で構成したときは、その耐摩耗性ゴムが摩滅等するまでの間、長期間にわたって高い耐摩耗を発揮させることができる。   On the other hand, the contact surface portion of the crosspiece, which is opposite to the contact surface side portion with the object to be conveyed, relative to the roller, the disk pulley, and the falling supply object is relatively compared with other rubber types. When the rubber type is excellent in wear resistance, high wear resistance can be exhibited over a long period of time until the wear-resistant rubber is worn away.

このようなコンベアにおいて、波形桟および横桟の少なくとも一方の、被搬送物との接触表面側部分を、たとえば、シリコーン、脂肪酸アミド等を含む撥水性のゴムにより、そして、その表面側部分とは反対側の表面部分を、たとえば、ブタジェンゴム等を含む、または、ＪＩＳ Ａ硬度が７０以上の高硬度の耐摩耗性のゴムによりそれぞれ構成したときは、桟が三層以上の積層構造になる場合にあっても、撥水性ゴムおよび耐摩耗性ゴムの両者を、それらが摩滅等するまで同時に機能させて、その撥水性ゴムをもって、桟への被搬送物の付着を、長期間にわたって十分に防止し、併せて、耐摩耗性ゴムによって、桟の耐摩耗性を、長期間にわたって十分に高めることができる。   In such a conveyor, at least one of the corrugated beam and the horizontal beam, the contact surface side portion with the object to be conveyed is made of water-repellent rubber containing, for example, silicone, fatty acid amide, and the surface side portion. When the opposite surface portion includes, for example, butadiene rubber or the like, or when the crosspiece has a laminated structure of three or more layers when each is composed of a high-abrasion rubber having a JIS A hardness of 70 or higher, Even in such a case, both the water-repellent rubber and the wear-resistant rubber are allowed to function at the same time until they wear out, and the water-repellent rubber sufficiently prevents the object to be transported from adhering to the crosspiece over a long period of time. In addition, the wear resistance rubber can sufficiently enhance the wear resistance of the crosspiece over a long period of time.

またここで、いずれの種類のゴムも、天然ゴムを共通成分としてなるものとしたときは、桟の厚み方向での二種類以上のゴムの積層接合を、接着剤等を用いることなしに、直接的な加硫接着によって簡易に、かつ確実に行うことができる。   Here, when any kind of rubber is made of natural rubber as a common component, two or more kinds of rubber in the thickness direction of the crosspiece can be directly joined without using an adhesive or the like. It can be carried out easily and reliably by a typical vulcanization adhesion.

そして、波形桟および横桟の少なくとも一方に、帆布等からなる補強層を埋設したときは、桟の強度を十分に高めることができる。
なお、この補強層を、ゴム被覆を施した状態として埋設させる場合は、その被覆ゴムもまた、共通成分としての天然ゴムを有するものとすることが、補強層の積層接合を簡易にして強固なものとする上で好ましい。 And when the reinforcement layer which consists of canvas etc. is embed | buried in at least one of a corrugated crosspiece and a horizontal crosspiece, the intensity | strength of a crosspiece can fully be raised.
When this reinforcing layer is embedded in a state where a rubber coating is applied, the covering rubber also has a natural rubber as a common component. It is preferable for the purpose.

ところで、先に述べたように、桟の一方の表面部分を撥水性のゴムで、そして、反対側の表面部分を耐摩耗性のゴムでそれぞれ構成する場合にあって、桟の頂部を耐摩耗性のゴムで覆ったときは、落下供給される被包装物による、桟の頂部の摩耗を、その耐摩耗性ゴムによって有効に保護することができる。   By the way, as mentioned above, when one surface portion of the crosspiece is made of water-repellent rubber and the opposite surface portion is made of wear-resistant rubber, the top portion of the crosspiece is wear-resistant. When covered with a conductive rubber, it is possible to effectively protect the wear of the top portion of the crosspiece due to the fall-supplied package by the wear-resistant rubber.

図１は、この発明に係るコンベアベルトを、その一部について、部分を破断除去して例示する断面斜視図であり、図中１は無端状に連続するベースベルトを、２は、ベースベルト１の両側部に立設されてベースベルト１の延在方向へ、波状に迂曲して延びる一対の波形桟を、そして３は、一対の波形桟２，２間で、ベースベルト１の延在方向に所定の間隔をおいて立設されてベースベルト１の幅方向に延びる横桟３をそれぞれ示す。   FIG. 1 is a cross-sectional perspective view illustrating a part of a conveyor belt according to the present invention, with a part thereof being broken and removed. In the figure, 1 is an endless continuous base belt, and 2 is a base belt 1. A pair of corrugated bars extending in a wavy shape extending in the extending direction of the base belt 1 in the extending direction of the base belt 1, and 3 an extending direction of the base belt 1 between the pair of corrugated bars 2 and 2 The crosspieces 3 are respectively shown standing at a predetermined interval and extending in the width direction of the base belt 1.

この図に示すところでは、ベースベルト１は、内部に埋設された一層の芯体帆布４ａと、この芯体帆布４ａを挟む二層の補強帆布４ｂとからなる補強層４によって補強され、また、各波形桟２は、それの厚みの中間部に埋設配置した、これも帆布からなる補強層５によって補強されている。なお、図に示すところからは明らかではないが、横桟３もまた、帆布等からなる埋設補強層をもって補強し得ることはもちろんである。   As shown in this figure, the base belt 1 is reinforced by a reinforcing layer 4 including a core canvas 4a embedded in one layer and two layers of reinforcing canvas 4b sandwiching the core canvas 4a. Each corrugated beam 2 is reinforced by a reinforcing layer 5 made of canvas, which is embedded in the middle of its thickness. Of course, the horizontal rail 3 can also be reinforced with a buried reinforcing layer made of canvas or the like, although it is not clear from the drawing.

ところで、横桟に関し、図示の横桟３は、ベースベルト１に対して垂直に立設させているも、このコンベアベルトを傾斜コンベアとして用いるときは、横桟３の立設形態を、図２に断面斜視図で例示するように、突出端部が上方側に向く傾斜形態または、折れ曲がり傾斜形態とすることもできる。   Incidentally, with respect to the horizontal rail, the illustrated horizontal rail 3 is erected vertically with respect to the base belt 1, but when this conveyor belt is used as an inclined conveyor, the horizontal beam 3 is erected in FIG. As shown in the cross-sectional perspective view, it is also possible to adopt an inclined form in which the projecting end portion is directed upward or a bent inclined form.

ここで、図１に示す横桟３は、傾向として、最も匂配の小さい傾斜コンベアに用いて好適であり、また、図２（ａ）および（ｂ）に示すそれぞれの横桟３は、順次匂配の大きい傾斜コンベアに用いて好適である。   Here, as a tendency, the horizontal rail 3 shown in FIG. 1 is suitable for use in an inclined conveyor having the smallest odor distribution, and the horizontal rails 3 shown in FIGS. It is suitable for use in an inclined conveyor having a large odor.

そしてここでは、波形桟２および横桟３の少なくとも一方、好ましくはそれらの両者を、厚み方向に接合された、所要の物性を有する二種類以上のゴムの積層構造になるものとする。   In this case, it is assumed that at least one of the corrugated beam 2 and the horizontal beam 3, preferably both of them, has a laminated structure of two or more kinds of rubber having required physical properties joined in the thickness direction.

この場合、より好ましくは、桟２，３の、被搬送物との接触表面側部分、たとえば、一対の波形桟２では、補強層５より内側となる相互の対向表面側部分を、そして横桟３では、傾斜コンベアとして用いたときに上側となって、被搬送物を支持することとなる表面側部分を、たとえば、シリコン、脂肪酸アミド等を含む撥水性のゴム２ａ，３ａによって構成する一方で、上記の表面側部分とは反対側の表面側部分、たとえば、一対の波形桟２では、補強層５より外側となって、ローラやディスクプーリ等と接触することのある外表面側部分を、また横桟３では、傾斜コンベアとして用いたときに、被搬送物を支持することとなる表面側部分とは反対側の表面部分、とくに、図２（ａ），（ｂ）に示すように傾斜し、または、折れ曲がり傾斜した形態を有する横桟３では、コンベアベルトの平坦姿勢の下での被搬送物の落下供給に際して、被搬送物が衝突することになる外表面側部分を、たとえば、ブタジェンゴム等を含む、または、ＪＩＳ Ａ硬度が７０以上の高硬度をもつ耐摩耗性のゴム２ｂ，３ｂにより構成する。   In this case, more preferably, the crossing surface side portion of the rails 2 and 3 with the object to be conveyed, for example, in the pair of corrugated rails 2, the mutually facing surface side portions inside the reinforcing layer 5, and the horizontal rail 3, the surface side portion that becomes the upper side when used as an inclined conveyor and supports the object to be conveyed is constituted by, for example, water-repellent rubbers 2 a and 3 a containing silicon, fatty acid amide, and the like. The surface side portion opposite to the surface side portion described above, for example, in the pair of corrugated bars 2, the outer surface side portion which is outside the reinforcing layer 5 and may come into contact with a roller, a disk pulley, etc. Further, the horizontal rail 3 is inclined as shown in FIGS. 2 (a) and 2 (b), when it is used as an inclined conveyor, the surface portion on the opposite side to the surface side portion that will support the object to be conveyed. Or bend and tilt In the horizontal rail 3 having the form, the outer surface side portion where the conveyed object collides when the conveyed object is dropped and supplied under the flat posture of the conveyor belt includes, for example, butadiene rubber or the like, or JIS It is composed of wear-resistant rubbers 2b and 3b having a high hardness of 70 or higher.

このように構成してなるコンベアベルトによれば、被搬送物に接触する撥水性ゴム２ａ，３ａの作用に基き、その被搬送物がたとえ水分を含む場合であっても、それを搬送するコンベアベルトが、キャリヤ側からリターン側へ反転されると同時に、被搬送物の全てが、所定の集積個所に確実に落下されることになる。従って、このコンベアベルトでは、それに付着残留した被搬送物が、リターン経路の途中でコンベアベルトから落下して、そのリターン経路の周辺を汚損するおそれを十分に取り除くことができる。   According to the conveyor belt configured as described above, the conveyor that conveys the water to be conveyed, even if the object to be conveyed contains moisture, based on the action of the water-repellent rubbers 2a and 3a that are in contact with the object to be conveyed. At the same time that the belt is reversed from the carrier side to the return side, all of the conveyed objects are surely dropped to a predetermined accumulation location. Therefore, with this conveyor belt, it is possible to sufficiently eliminate the possibility that the object to be transported remaining on the conveyor belt will fall from the conveyor belt in the middle of the return path and contaminate the periphery of the return path.

またこのコンベアベルトでは、波形桟２の耐摩耗性ゴム２ｂの作用により、通常は、一対の波形桟２より外側で、ベースベルト１の側部に摩擦接触することになるローラやディスクプーリ等に、コンベアベルトの蛇行等に起因して、波形桟２の外表面が接触することがあっても、波形桟２の摩耗を長期間にわたって効果的に防止することができる。   Further, in this conveyor belt, due to the action of the wear-resistant rubber 2b of the corrugated beam 2, the roller belt or the disk pulley or the like that normally comes into frictional contact with the side portion of the base belt 1 outside the pair of corrugated beams 2 is used. Even if the outer surface of the corrugated beam 2 comes into contact due to the meandering of the conveyor belt, wear of the corrugated beam 2 can be effectively prevented over a long period of time.

そして、横桟３の耐摩耗性ゴム３ｂは、とくにその横桟３が図２（ａ），（ｂ）に示すような立設形態を有するものである場合に、平坦姿勢としたコンベアベルト上に、被搬送物を落下供給するに当り、横桟３の外表面を被搬送物の衝突に伴う摩耗から有効に保護することができる。   The wear-resistant rubber 3b of the crosspiece 3 is on the conveyor belt having a flat posture especially when the crosspiece 3 has a standing configuration as shown in FIGS. 2 (a) and 2 (b). In addition, the outer surface of the horizontal rail 3 can be effectively protected from wear caused by the collision of the conveyed object when the conveyed object is dropped and supplied.

以上のようなコンベアベルトにおいて、二種類以上、たとえば三種類以上のゴムの積層構造体とすることができる波形桟２および横桟３は、いずれの種類のゴムにも共通のゴム成分、一般的には天然ゴム成分を含有させることが、それぞれの種類のゴムを、加硫接着をもって簡易に、かつ確実に接合させ得る利点がある。   In the conveyor belt as described above, the corrugated beam 2 and the horizontal beam 3 that can be a laminated structure of two or more types, for example, three or more types of rubber, are common rubber components for all types of rubber. Including the natural rubber component, there is an advantage that each kind of rubber can be easily and surely bonded with vulcanization adhesion.

またここで、波形桟２および横桟３の少なくとも一方に、図１で、波形桟２について例示するような補強層を埋設配置した場合には、補強層の層数に応じて桟２，３の耐張強度を高めることができる。   Here, in the case where a reinforcing layer as illustrated in FIG. 1 is embedded in at least one of the corrugated beam 2 and the horizontal beam 3, the beams 2, 3 according to the number of reinforcing layers. The tensile strength of can be increased.

ところで、波形桟２および横桟３の少なくとも一方の頂部、たとえば、図３に例示するように、それぞれの桟２，３の頂部を、耐摩耗性ゴム２ｂ，３ｂで覆った場合は、平坦姿勢としたコンベアベルト上への被搬送物の落下供給に当り、その耐摩耗性ゴム２ｂ，３ｂによって、波形桟２および横桟３のそれぞれの頂部を摩耗から有効に保護することができる。   By the way, when the top of at least one of the corrugated beam 2 and the horizontal beam 3, for example, the top of each beam 2, 3 is covered with wear-resistant rubbers 2b, 3b, a flat posture is obtained. When the conveyed object is dropped on the conveyor belt, the top portions of the corrugated beam 2 and the horizontal beam 3 can be effectively protected from wear by the wear-resistant rubbers 2b and 3b.
