Description
本発明は、例えば穀物類や鉱石粉末などを搬送する搬送用ホース、詳しくはホース内面を摩耗させやすい穀物類や鉱石粉末などの被搬送物の搬送に好適な搬送用ホースに関するものである。
The present invention relates to a transport hose for transporting, for example, cereals or ore powder, and more particularly to a transport hose suitable for transporting a transported object such as cereals or ore powder that easily wears the inner surface of the hose.
従来から穀物類や鉱石粉末などを搬送する搬送用ホースはゴムを主材料にして作られており、内面が被搬送物との摩擦により摩耗しやすいという問題がある。そこで、このような摩耗を防止し耐久性を向上するために、例えば特許文献１（特開２００７－２５４６１６号公報）に開示されているように、ゴム材と、粉砕された硬質材及び／又は粉粒状の硬質材とを混合してなる混合物からなる機能性被覆材を搬送用ホースの内面に装着する技術が知られている。
Conventionally, a transport hose for transporting grains, ore powder, etc. is made of rubber as a main material, and there is a problem that the inner surface is easily worn by friction with a transported object. Therefore, in order to prevent such wear and improve durability, for example, as disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2007-254616), a rubber material, a pulverized hard material, and / or A technique is known in which a functional coating material made of a mixture obtained by mixing a powdered hard material is attached to the inner surface of a transport hose.
上記特許文献１に開示されている機能性被覆材はゴム材と、粉砕された硬質材及び／又は粉粒状の硬質材とを混合してなる混合物からなるものであって、ゴム材と混ぜるために硬質材を粉粒状に破砕しなければならないという問題、この被覆材を内面に装着した搬送用ホース内に穀物類や鉱石粉末などを搬送したときに被覆材のゴム材が摩耗損傷するという問題などがある。
The functional coating material disclosed in Patent Document 1 is composed of a mixture of a rubber material and a pulverized hard material and / or a powdered hard material, and is mixed with the rubber material. The problem is that the hard material must be crushed into a granular shape, and the rubber material of the coating material is worn and damaged when conveying grains, ore powder, etc. into the conveying hose with the coating material on the inner surface. and so on.
本発明の目的は、このような課題を解決するものであり、ホース内面の摩耗損傷を防止することのできる搬送用ホースを提供することにある。
An object of the present invention is to solve such problems and to provide a transport hose that can prevent wear damage on the inner surface of the hose.
本発明の搬送用ホースは、ホースの内面全面を覆うようにセラミック粒体が密に敷き詰められてなる搬送用ホースであって、前記セラミック粒体はセラミック材料を用いてプレス成型により強固に形成されていて、セラミック粒体の形は両端面が円形の軸芯方向長さが短い円柱状を呈しており、セラミック粒体をホースの内面全面を覆うように密に敷き詰めてホースの内面をセラミック粒体の一端面で形成される凹凸のないフラットな状態としたことを特徴とする。
The conveying hose of the present invention is a conveying hose in which ceramic particles are densely spread so as to cover the entire inner surface of the hose, and the ceramic particles are firmly formed by press molding using a ceramic material. In addition, the shape of the ceramic particles is cylindrical with both end faces circular and the axial length is short, and the ceramic particles are densely laid so as to cover the entire inner surface of the hose, and the inner surface of the hose is ceramic particles. It is characterized by having a flat state with no irregularities formed on one end surface of the body.
以上のように、本発明の搬送用ホースは、セラミック粒体の一端面で形成されるホースの内面は全面が凹凸のないフラットな状態となり、ホース内に穀物類や鉱石粉末などの被搬送物が通るときにホース自体がセラミック粒体により保護されるとともに、セラミック粒体が被搬送物により削り取られることも少なくなり、長期に亘ってホースの内面を保護することができる。しかも、セラミック粒体の形は両端面が円形の軸芯方向長さが短い円柱状を呈しているので、隣接する３つのセラミック粒体で隙間が形成されることになり、その隙間が遊びとなり、ホースの可撓性を損なうようなこともない。
As described above, the transport hose of the present invention is such that the entire inner surface of the hose formed by one end surface of the ceramic particles is flat with no irregularities, and a material to be transported such as grains or ore powder in the hose. When the hose passes, the hose itself is protected by the ceramic particles, and the ceramic particles are less likely to be scraped off by the object to be conveyed, and the inner surface of the hose can be protected over a long period of time. Moreover, since the shape of the ceramic particles has a cylindrical shape with both end faces being circular and the axial length is short, a gap is formed by three adjacent ceramic particles, and the gap becomes play. In addition, the flexibility of the hose is not impaired.
以下、本発明の一実施の形態を、図１～図４を用いて具体的に説明する。
Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.
図において、１はゴムを主材料にして作られた搬送用のホース２の内面全面を覆うように敷き詰められるセラミック粒体で、このセラミック粒体１はセラミック材料を用いてプレス成型により強固に形成されている。そして、このセラミック粒体１の形は両端面が円形の軸芯方向長さが短い円柱状を呈している。この小さい粒状のセラミック粒体１をホース２の内面全面に密に敷き詰めることによりホース２の内面全面を覆っている。
In the figure, reference numeral 1 denotes a ceramic particle which is laid so as to cover the entire inner surface of a transport hose 2 made of rubber as a main material, and this ceramic particle 1 is strongly formed by press molding using a ceramic material. Has been. And the shape of this ceramic particle 1 is exhibiting the column shape with a short axial center direction length where both end surfaces are circular. The small inner surface of the hose 2 is covered with the small granular ceramic particles 1 so as to cover the entire inner surface of the hose 2.
ホース２の内面全面にセラミック粒体１を敷き詰めるタイミングとしては、ホース２自体が円筒状（ホース状）に作られる前の段階、つまりフラットな状態のときであり、そのときに内面側となる片面にセラミック粒体１が敷き詰められる。さらに詳しくは、セラミック粒体１をホース２の内面側となる片面に敷き詰める工程について述べると、先ず無数のセラミック粒体１が布粘着テープ３の粘着面に密に載せられる。そのとき、セラミック粒体１の一端側の端面が布粘着テープ３の粘着面に貼着保持される。このように布粘着テープ３の粘着面で保持された無数のセラミック粒体１の他端側の端面に接着剤を塗布し、この接着剤の塗布面に生ゴムシート４を貼り付ける。このように生ゴムシート４が貼り付けられた無数のセラミック粒体１を布粘着テープ３ごと掴んで、ホース２の内面側となる片面にセラミック粒体１と一体の生ゴムシート４を当てがう。かかる状態で生ゴムシート４に熱を掛けて加硫させることにより、生ゴムシート４のゴムが隣接する３つのセラミック粒体１で形成される隙間５を埋めるとともにホース２側と一体結合される。このように無数のセラミック粒体１が密に装着されたホース材料によりホース２が形成されるものである。
The timing at which the ceramic particles 1 are spread over the entire inner surface of the hose 2 is the stage before the hose 2 itself is made into a cylindrical shape (hose shape), that is, in a flat state. Ceramic particles 1 are spread on the surface. More specifically, the process of laying the ceramic particles 1 on one side which is the inner surface side of the hose 2 will be described. First, innumerable ceramic particles 1 are densely placed on the adhesive surface of the cloth adhesive tape 3. At that time, the end surface on one end side of the ceramic particles 1 is stuck and held on the adhesive surface of the cloth adhesive tape 3. In this way, an adhesive is applied to the end face on the other end side of the countless ceramic particles 1 held by the adhesive face of the cloth adhesive tape 3, and the raw rubber sheet 4 is attached to the adhesive application face. The countless ceramic particles 1 to which the raw rubber sheet 4 is thus attached are gripped together with the cloth adhesive tape 3, and the raw rubber sheet 4 integrated with the ceramic particles 1 is applied to one side which is the inner surface side of the hose 2. In such a state, the raw rubber sheet 4 is heated and vulcanized, whereby the rubber of the raw rubber sheet 4 fills the gap 5 formed by the three adjacent ceramic particles 1 and is integrally coupled to the hose 2 side. Thus, the hose 2 is formed of a hose material in which countless ceramic particles 1 are closely attached.
この完成されたホース２の内面には前記布粘着テープ３が残ったままであり、被搬送物の種類、例えば搬送中に被搬送物との摩擦により発生する布粘着テープ３の小片が混ざっても影響がない鉱石粉末などの場合は布粘着テープ３をセラミック粒体１の一端面から剥さずに、ホース２を搬送用としてそのまま使用しても良いが、被搬送物が穀物のような食料の場合は布粘着テープ３をセラミック粒体１の一端面から剥しておく必要がある。なぜならば、搬送中の摩耗により発生する布粘着テープ３の小片が穀物に混ざってしまうと後の処理に問題があるからである。何れにしても、ホース２の内面は全面が凹凸のないフラットな状態でセラミック粒体１により保護されており、ホース２内に穀物類や鉱石粉末などの被搬送物が通るとき、セラミック粒体１が被搬送物により削り取られることも少なくなり、長期に亘ってホース２の内面を保護することができるようになる。
Even if the cloth adhesive tape 3 remains on the inner surface of the completed hose 2 and a small piece of the cloth adhesive tape 3 generated due to friction with the object to be conveyed during conveyance, for example, is mixed. In the case of ore powder or the like that has no effect, the hose 2 may be used as it is for transportation without peeling off the cloth adhesive tape 3 from one end face of the ceramic granule 1, but the transported object is food such as grain. In this case, the cloth adhesive tape 3 needs to be peeled off from one end surface of the ceramic particle 1. This is because if the piece of cloth adhesive tape 3 generated due to wear during conveyance is mixed with the grain, there is a problem in the subsequent processing. In any case, the inner surface of the hose 2 is protected by the ceramic particles 1 so that the entire surface is flat with no irregularities, and when a material to be conveyed such as grains or ore powder passes through the hose 2, the ceramic particles 1 is less likely to be scraped off by the conveyed object, and the inner surface of the hose 2 can be protected over a long period of time.
