Description

本発明は、紡績におけるコーマー工程、練篠工程、粗紡工程、精紡工程等で使用される紡績用ローラーに関する。   The present invention relates to a spinning roller used in a comber process, a spinning process, a roving process, a fine spinning process, and the like in spinning.

従来、この種紡績用ローラーとしては、図４に示すように、アルミニウム等の金属製パイプ(32)の外周面に接着剤を塗布した上、押出成形した未加硫のゴムコット(31)を嵌め被せて、該ゴムコット(31)を加硫接着したローラー(30)が知られている。そして、該紡績ローラー(30)における前記金属製パイプ(32)内には芯金(33)が圧入されていた。   Conventionally, as this kind of spinning roller, as shown in FIG. 4, an adhesive is applied to the outer peripheral surface of a metal pipe (32) such as aluminum, and then an unvulcanized rubber cot (31) is formed by extrusion. A roller (30) that is covered and vulcanized and bonded to the rubber cot (31) is known. The cored bar (33) was press-fitted into the metal pipe (32) of the spinning roller (30).

また、他の紡績用ローラーとして、図５に示すように、芯金(41)の外周に接着剤を介して、チューブ状の軟質ゴムコット(42)を固定し、更に軟質ゴムコット(42)の外周に、該ゴムコット(42)より硬度が高いポリウレタンゴムチューブ(43)を嵌め被せたり、或いは接着剤で固定したローラー(40)も知られている。

紡績用ローラーは、その使用に伴って外周面が磨耗することから、該磨耗を抑制するためにはゴム硬度を高くするのが好ましいが、硬度が高くした場合、繊維の把持力が低下し、いわゆる糸斑が発生し易くなる。そのため、紡績用ローラーは、その外周面の磨耗を抑制しつつ、しかも繊維の十分な把持力が確保されるものでなければならない。   Since the outer peripheral surface of the spinning roller wears with its use, it is preferable to increase the rubber hardness in order to suppress the wear, but when the hardness is increased, the gripping force of the fiber decreases, So-called thread spots are easily generated. For this reason, the spinning roller must be capable of ensuring a sufficient gripping force of the fibers while suppressing wear on the outer peripheral surface thereof.

前述した従来の紡績用ローラーのうち、前者は金属製パイプ(32)の外周に一層のゴムチューブ(31)が接着された構造であるため、耐磨耗性と繊維の把持力の両方の性質を兼ね備えたものを得るのは実際上、非常に困難であった。   Among the conventional spinning rollers described above, the former has a structure in which a single rubber tube (31) is bonded to the outer periphery of a metal pipe (32), so both the properties of wear resistance and fiber gripping force It was actually very difficult to obtain a product that had both.

一方、後者の紡績用ローラーでは、軟質ゴムコット(42)の外周に、該ゴムコット(42)より硬度が高いポリウレタンゴムチューブ(43)が被着されているため、外側のポリウレタンゴムチューブ(43)層によって耐磨耗性が得られ、内側の軟質ゴムコット(42)層によって、繊維の把持力が得られ易いが、軟質ゴムコット(42)の内周面を接着剤で芯金(41)の外周面に直接接着する構造であるため、使用済ゴムローラーの交換作業が面倒であるという問題がある他、内側の軟質ゴムコット(42)層と外側のポリウレタンゴムチューブ(43)層とを複合した見かけ硬度を制御するものではなかったため、期待した効果を得難いのが実情であった。   On the other hand, in the latter spinning roller, since the polyurethane rubber tube (43) having a higher hardness than the rubber cot (42) is attached to the outer periphery of the soft rubber cot (42), the outer polyurethane rubber tube (43) layer Wear resistance is obtained by the inner soft rubber cot (42) layer, and it is easy to obtain fiber gripping force, but the inner peripheral surface of the soft rubber cot (42) is bonded to the outer peripheral surface of the core metal (41) with an adhesive. In addition to troublesome replacement of used rubber rollers, the apparent hardness combined with the inner soft rubber cot (42) layer and the outer polyurethane rubber tube (43) layer. The fact was that it was difficult to obtain the expected effect because it was not a control.

本発明の目的は、使用済みゴムローラーの交換作業が容易に行え、且つ耐磨耗性と繊維の十分な把持力を容易に得ることができる紡績用ローラーを提供することにある。   An object of the present invention is to provide a spinning roller capable of easily replacing a used rubber roller and easily obtaining abrasion resistance and a sufficient gripping force of fibers.

請求項１記載の本発明は、金属または合成樹脂製のパイプと、パイプの外周面に形成された接着剤層と、接着剤層を介してパイプの外周側に被着された第一ゴム層と、第一ゴム層の外周側に形成された第二ゴム層とを含み、第ニゴム層の硬度が第一ゴム層の硬度より高く設定されている紡績用ローラーである。なお、第一ゴム層と第二ゴム層との間に、接着剤層や糸、布等で構成された他の層を設けても良い。   The present invention according to claim 1 is a pipe made of metal or synthetic resin, an adhesive layer formed on the outer peripheral surface of the pipe, and a first rubber layer deposited on the outer peripheral side of the pipe via the adhesive layer And a second rubber layer formed on the outer peripheral side of the first rubber layer, and a spinning roller in which the hardness of the second rubber layer is set higher than the hardness of the first rubber layer. In addition, you may provide the other layer comprised by the adhesive bond layer, the thread | yarn, the cloth, etc. between the 1st rubber layer and the 2nd rubber layer.

請求項２記載の本発明は、前記請求項１記載の紡績用ローラーについて、第二ゴム層が、第一ゴム層の外周面に形成された第二接着剤層を介して前記第一ゴム層の外周側に被着されているものである。   According to a second aspect of the present invention, in the spinning roller according to the first aspect, the second rubber layer is formed through the second adhesive layer formed on the outer peripheral surface of the first rubber layer. It is attached to the outer peripheral side of.

請求項３記載の本発明は、前記請求項１または請求項２記載の紡績用ローラーについて、 第一ゴム層の硬度が６０°以下であり、第ニゴム層の硬度が６０℃以上であることを特徴とするものである。なお、第一ゴム層の硬度は、好ましくは３５°〜５０°の範囲であり、第二ゴム層の硬度は、好ましく７０°〜９５°の範囲である。   According to a third aspect of the present invention, in the spinning roller according to the first or second aspect, the hardness of the first rubber layer is 60 ° or less, and the hardness of the second rubber layer is 60 ° C. or more. It is a feature. The hardness of the first rubber layer is preferably in the range of 35 ° to 50 °, and the hardness of the second rubber layer is preferably in the range of 70 ° to 95 °.

なお、本明細書において、硬度はＪＩＳＫ６２５３に定義されるタイプＡデュロメータ硬さである。   In addition, in this specification, hardness is a type A durometer hardness defined in JISK6253.

請求項４記載の本発明は、前記請求項１〜請求項３のうちのいずれか一項記載の紡績用ローラーについて、ローラー表面の見かけ硬度が５０°〜８０°の範囲であることを特徴とするものである。なお、紡績用ローラー表面の見かけ硬度は、好ましく６０°〜７０°の範囲である。   The invention according to claim 4 is characterized in that the apparent hardness of the roller surface is in the range of 50 ° to 80 ° with respect to the spinning roller according to any one of claims 1 to 3. To do. The apparent hardness of the spinning roller surface is preferably in the range of 60 ° to 70 °.

請求項５記載の本発明は、前記請求項１〜請求項４のうちのいずれか一項記載の紡績用ローラーについて、第ニゴム層の厚みが０．５〜５ｍｍの範囲であることを特徴とするものである。   The present invention according to claim 5 is characterized in that, in the spinning roller according to any one of claims 1 to 4, the thickness of the second rubber layer is in the range of 0.5 to 5 mm. To do.

第ニゴム層の厚みが０．５ｍｍ未満である場合には、当該紡績用ローラーが少し磨耗しただけで当該ローラー表面の見かけ硬度が急激に低下してしまい、見かけ硬度の制御が困難となる。一方、第二ゴム層の厚みが５ｍｍを超える場合には、相対的に低硬度である第一ゴム層の影響をほとんど受けなくなり、その結果、当該紡績用ローラー表面の見かけ硬度低下効果が期待できなくなるので好ましくない。   When the thickness of the second rubber layer is less than 0.5 mm, the apparent hardness of the surface of the roller is drastically reduced even if the spinning roller is slightly worn, making it difficult to control the apparent hardness. On the other hand, when the thickness of the second rubber layer exceeds 5 mm, it is hardly affected by the first rubber layer having a relatively low hardness, and as a result, an effect of reducing the apparent hardness of the spinning roller surface can be expected. Since it disappears, it is not preferable.

なお、前述した本発明に係る紡績用ローラーは、紡績におけるコーマー工程、練篠工程、粗紡工程、精紡工程等のいずれにおいても使用し得るものである。   The spinning roller according to the present invention described above can be used in any of the comber process, the spinning process, the roving process, the fine spinning process and the like in spinning.

本発明の紡績用ローラーにおける第一ゴム層と第ニゴム層の原料としては、ＮＢＲの他、天然ゴム、ＳＢＲ、ＢＲ、ＩＩＲ等、種々のものが用いられる。   As raw materials for the first rubber layer and the second rubber layer in the spinning roller of the present invention, various materials such as NBR, natural rubber, SBR, BR, IIR and the like are used.

本発明の紡績用ローラーは、金属または合成樹脂製のパイプと、パイプの外周面に形成された第一接着剤層と、第一接着剤層を介してパイプの外周側に被着された第一ゴム層と、第一ゴム層の外周面に、第ニ接着剤層を介するか、または直接に第二ゴム層を設けた構造であるため、前記パイプ内に芯金を圧入することで当該紡績用ローラーの取付が行え、従来の接着剤を用いた芯金への取付が不要となることから、使用済ゴムローラーの交換作業が容易であると共に、接着剤使用による作業環境の悪化が防止される。また、本発明の紡績用ローラーは、前述した通り、パイプをベースとして、その外周側に第一接着剤層、或いは更に第ニ接着剤層を介して第一ゴム層と第二ゴム層を設けた有機的な多層構造であって、第一ゴム層よりも硬度が高い第二ゴム層によって、紡績時の耐磨耗性が得られると共に、繊維の捲き付きが防止できる一方、第二ゴム層よりも柔軟な第一ゴム層が、第二ゴム層と一体となっていることにより、当該ローラーの見かけ硬度を適切に下げるため、繊維の十分な把持力が得られ、しかもこれら耐磨耗性、繊維の捲き付き防止および繊維把持力のすべての機能が安定的に維持されることから、いわゆる糸斑の発生が確実に防止され、高品質で均整な糸を生産することができる。   The spinning roller of the present invention includes a pipe made of metal or synthetic resin, a first adhesive layer formed on the outer peripheral surface of the pipe, and a first adhesive layer attached to the outer peripheral side of the pipe via the first adhesive layer. Since the first rubber layer and the first rubber layer have a structure in which the second adhesive layer is provided directly on the outer peripheral surface of the first rubber layer, or the second rubber layer is directly provided, the core metal is press-fitted into the pipe. The spinning roller can be installed, and it is no longer necessary to attach the core to the core using an adhesive, making it easy to replace the used rubber roller and preventing the working environment from deteriorating due to the use of the adhesive. Is done. Further, as described above, the spinning roller according to the present invention is provided with the first rubber layer and the second rubber layer on the outer peripheral side of the pipe as a base, with the first adhesive layer or further the second adhesive layer interposed therebetween. The second rubber layer, which has an organic multilayer structure and has higher hardness than the first rubber layer, provides abrasion resistance during spinning and prevents fiber seizure. The first rubber layer, which is more flexible, is integrated with the second rubber layer, so that the apparent hardness of the roller is appropriately lowered, so that sufficient gripping force of the fibers can be obtained, and these abrasion resistance Since all the functions of fiber seizure prevention and fiber gripping force are stably maintained, the occurrence of so-called yarn unevenness is reliably prevented, and a high-quality and even yarn can be produced.
