Description
本発明は、糸加熱ローラの保温箱、及び、その製造方法に関する。 The present invention relates to a heat insulation box for a yarn heating roller and a method for manufacturing the same.
特許文献１には、紡糸装置から紡出された複数の糸を、加熱して延伸する装置が開示されている。この装置は、糸を延伸するための２つのローラユニットを有する。各ローラユニットは、加熱ローラ（ゴデットローラ）とセパレートローラを有する。各ローラユニットにおいて、糸は加熱ローラとセパレートローラとの間で複数回巻回され、その間の加熱ローラとの接触によって糸は所定温度まで加熱される。また、糸走行方向下流側に位置するローラユニットの加熱ローラは、上流側に位置するローラユニットの加熱ローラよりも回転速度（糸送り速度）が速くなっている。これにより、上流側のローラユニットで予熱された糸が、２つのローラユニットの間の速度差によって延伸される。 Patent Document 1 discloses an apparatus for heating and stretching a plurality of yarns spun from a spinning device. This device has two roller units for drawing the yarn. Each roller unit has a heating roller (godet roller) and a separate roller. In each roller unit, the yarn is wound a plurality of times between the heating roller and the separation roller, and the yarn is heated to a predetermined temperature by contact with the heating roller therebetween. In addition, the heating roller of the roller unit located on the downstream side in the yarn traveling direction has a higher rotational speed (yarn feeding speed) than the heating roller of the roller unit located on the upstream side. As a result, the yarn preheated by the upstream roller unit is drawn by the speed difference between the two roller units.
ところで、上記特許文献１において、加熱ローラを含むローラユニットは、保温箱に収容されている。保温箱の具体的な構成については、特許文献１には特に記載がないが、例えば、以下のような構成の保温箱が知られている。図８は、従来の保温箱の斜視図である。図８に示す保温箱１００は、それぞれステンレス鋼等の金属板で形成された、箱体１０１と枠体１０１ｃとを有する。また、箱体１０１の内壁１０１ａと外壁１０１ｂとの間には、ロックウール等の不定形の断熱材１０３が充填されている。 By the way, in the said patent document 1, the roller unit containing a heating roller is accommodated in the heat insulation box. The specific structure of the heat insulation box is not particularly described in Patent Document 1, but for example, a heat insulation box having the following structure is known. FIG. 8 is a perspective view of a conventional heat insulation box. A heat retaining box 100 shown in FIG. 8 includes a box body 101 and a frame body 101c each formed of a metal plate such as stainless steel. Further, between the inner wall 101a and the outer wall 101b of the box 101, an insulative heat insulating material 103 such as rock wool is filled.
上記の保温箱１００は、以下のようにして作製する。まず、箱体１０１の内壁１０１ａと外壁１０１ｂとを、複数枚の金属板を溶接にて互いに接合することによって組み立てる。また、内壁１０１ａと外壁１０１ｂとの間には、複数の補強リブを設ける。次に、箱体１０１の内壁１０１ａと外壁１０１ｂとの間に、ロックウール等の断熱材１０３を充填する。その後、箱体１０１に枠体１０１ｃを溶接にて取り付けて、内壁１０１ａと外壁１０１ｂとの間の、断熱材１０３が充填された隙間を塞ぐ。尚、図８には図示が省略されているが、この保温箱１００には、前面を覆う扉が開閉自在に取り付けられる。この扉も、箱体１０１と同様、全周が金属板で囲われ、その内部にはロックウール等の、不定形の断熱材が充填された保温構造となっている。 The heat insulation box 100 is manufactured as follows. First, the inner wall 101a and the outer wall 101b of the box body 101 are assembled by joining a plurality of metal plates to each other by welding. A plurality of reinforcing ribs are provided between the inner wall 101a and the outer wall 101b. Next, a heat insulating material 103 such as rock wool is filled between the inner wall 101 a and the outer wall 101 b of the box body 101. Thereafter, the frame body 101c is attached to the box body 101 by welding to close the gap filled with the heat insulating material 103 between the inner wall 101a and the outer wall 101b. In addition, although illustration is abbreviate | omitted in FIG. 8, the door which covers a front surface is attached to this heat insulation box 100 so that opening and closing is possible. As with the box 101, this door is surrounded by a metal plate and has a heat retaining structure filled with an insulative heat insulating material such as rock wool.
図８に示す従来の保温箱では、次のような問題が存在する。まず、大きな金属板を溶接によって複数枚接合して、外壁及び内壁を組み立てる作業は非常に手間がかかる。また、ロックウールの断熱性はそれほど高いものではないことから、保温箱としての断熱性能は低く、外部への放熱量、即ち、熱エネルギーの損失が大きくなっていた。また、箱体１０１の内壁１０１ａと外壁１０１ｂの間にロックウール等の不定形の断熱材１０３を充填する際に、内壁１０１ａの裏側や外壁１０１ｂ内の隅部など、手が届きにくい部分に断熱材１０３を充填することが難しい。従って、作業者の熟練度によっては、断熱材１０３の充填密度が不均一になる虞がある。 The conventional heat insulation box shown in FIG. 8 has the following problems. First, the work of joining a plurality of large metal plates by welding to assemble the outer wall and the inner wall is very laborious. Moreover, since the heat insulation property of rock wool is not so high, the heat insulation performance as a heat insulation box is low, and the heat radiation amount to the outside, that is, the loss of heat energy is large. In addition, when filling an insulative heat insulating material 103 such as rock wool between the inner wall 101a and the outer wall 101b of the box body 101, heat insulation is provided to parts that are difficult to reach such as the back side of the inner wall 101a and the corners in the outer wall 101b. It is difficult to fill the material 103. Therefore, depending on the skill level of the operator, the filling density of the heat insulating material 103 may be non-uniform.
なお、従来から広く用いられているロックウール等の断熱材は、不定形で全く剛性がないため、内壁１０１ａ及び外壁１０１ｂを構成する金属板によって、保温箱の剛性を確保する必要がある。しかし、剛性を上げるために金属板の厚みを厚くすると、保温箱が重くなって保全等の作業性が低下する。また、金属板を厚くする代わりに、内壁１０１ａと外壁１０１ｂとの間に補強リブを設けて保温箱の剛性を高める場合は、補強リブを介して、内部の熱が内壁１０１ａから外壁１０１ｂへ伝わるため、保温性が低下する。 In addition, since heat insulating materials such as rock wool that have been widely used in the past are indefinite and have no rigidity, it is necessary to ensure the rigidity of the heat insulation box with the metal plates that constitute the inner wall 101a and the outer wall 101b. However, if the thickness of the metal plate is increased in order to increase the rigidity, the heat insulation box becomes heavier and workability such as maintenance is reduced. In addition, when a reinforcing rib is provided between the inner wall 101a and the outer wall 101b to increase the rigidity of the heat insulating box instead of increasing the thickness of the metal plate, the internal heat is transmitted from the inner wall 101a to the outer wall 101b via the reinforcing rib. For this reason, the heat retention is reduced.
本発明の目的は、組立が容易な保温箱を提供することである。また、本発明の別の目的は、断熱性が高く、且つ、断熱性が均一化された、保温箱を提供することである。 An object of the present invention is to provide a heat insulation box that can be easily assembled. Another object of the present invention is to provide a heat insulation box having high heat insulation and uniform heat insulation.
第１の発明の糸加熱ローラの保温箱は、糸を加熱する糸加熱ローラを収容する保温箱であって、保温箱を構成する複数の箱壁部が、それぞれ、断熱板と、この断熱板に積層された金属製の補強板とを有することを特徴とするものである。 The heat retaining box of the yarn heating roller of the first invention is a heat retaining box that houses a yarn heating roller that heats the yarn, and each of the plurality of box wall portions constituting the heat retaining box includes a heat insulating plate and the heat insulating plate. And a metal reinforcing plate laminated on the substrate.
本発明によれば、保温箱の箱壁部が、金属製の補強板に、断熱板が積層された構造を有する。それ故、断熱板を補強板に積層することで各箱壁部を簡単に形成できる。補強板に断熱板を積層させて複数の箱壁部をそれぞれ先に形成してから接合してもよいし、予め複数の補強板を接合してからそれぞれの補強板に断熱板を積層させてもよいが、何れにしても、保温箱の組立が非常に容易である。また、例えば発泡樹脂等からなる断熱板の断熱性は、一般に、ロックウールなどと比べると数倍高い。従って、各箱壁部の断熱性が高くなり、ひいては、保温箱全体の断熱性能も向上する。さらに、断熱板の取付作業は、所定サイズの断熱板を補強板に積層するだけで完了し、不慣れな作業者が作業を行う場合でも、保温箱の断熱性が不均一になりにくい。 According to the present invention, the box wall portion of the heat insulation box has a structure in which a heat insulating plate is laminated on a metal reinforcing plate. Therefore, each box wall can be easily formed by laminating the heat insulating plate on the reinforcing plate. A plurality of box wall portions may be formed by laminating a heat insulating plate on the reinforcing plate and then joined together, or a plurality of reinforcing plates may be joined in advance and then the heat insulating plate laminated on each reinforcing plate. In any case, the assembly of the heat insulation box is very easy. Moreover, the heat insulating property of a heat insulating plate made of, for example, foamed resin is generally several times higher than that of rock wool or the like. Therefore, the heat insulation of each box wall part becomes high, and by extension, the heat insulation performance of the whole heat insulation box improves. Furthermore, the work of attaching the heat insulating plate is completed simply by laminating a heat insulating plate of a predetermined size on the reinforcing plate, and even when an unfamiliar operator performs the work, the heat insulating property of the heat insulating box is not likely to be uneven.
第２の発明の糸加熱ローラの保温箱は、前記第１の発明において、各箱壁部において、前記金属製の補強板は、前記断熱板の、保温箱の内側を向く内面、又は、保温箱の外側を向く外面の、何れか一方の面にのみ積層されていることを特徴とするものである。 The heat insulation box of the yarn heating roller according to the second invention is the heat insulation box according to the first invention, wherein the metal reinforcing plate is the inner surface of the heat insulating plate facing the inside of the heat insulation box or the heat insulation box. It is laminated | stacked only on either one surface of the outer surface which faces the outer side of a box.
上述した、図８に示すような従来の保温箱では、箱体１０１の内壁１０１ａと、外気に接する外壁１０１ｂとが、枠体１０１ｃや図示しない補強リブ等、熱伝導率が高い金属材料でつながっている。保温箱の扉についても同様である。このような構成であるが故に、熱伝導により内部の熱が外壁１０１ｂに伝わり、外気中に熱エネルギーが放出されている。また、外壁１０１ｂの温度が高くなるという問題もあった。 In the conventional heat insulation box as shown in FIG. 8 described above, the inner wall 101a of the box body 101 and the outer wall 101b in contact with the outside air are connected by a metal material having high thermal conductivity such as the frame body 101c or a reinforcing rib (not shown). ing. The same applies to the door of the heat insulation box. Because of such a configuration, internal heat is transmitted to the outer wall 101b by heat conduction, and heat energy is released into the outside air. There is also a problem that the temperature of the outer wall 101b becomes high.
この点、本発明では、熱伝導率が高い金属の補強板が、断熱板の内面または外面の何れか一方にしか積層されていないことから、補強板を伝わって内部の熱が外部へ逃げる熱量を抑制することができる。即ち、断熱板の外面にしか補強板がない場合は、保温箱内部の高温の空気が金属の補強板には直接触れず、断熱板を介してのみ外面の補強板に熱が伝わるので、外面の補強板が高温になることがなく、外面から放出される熱エネルギーの量が抑制される。また、断熱板の内面にしか補強板がない場合は、保温箱内部の高温の空気で内面の補強板は高温になるものの、断熱板で熱伝導が抑えられる。従って、保温箱の外面に伝わる熱エネルギーが抑えられ、外面から放出される熱エネルギーの量も抑制される。 In this regard, in the present invention, since the metal reinforcing plate having high thermal conductivity is laminated only on either the inner surface or the outer surface of the heat insulating plate, the amount of heat that is transferred to the outside through the reinforcing plate. Can be suppressed. That is, when there is a reinforcing plate only on the outer surface of the heat insulating plate, the hot air inside the heat insulation box does not directly touch the metal reinforcing plate, and heat is transferred to the outer reinforcing plate only through the heat insulating plate. Therefore, the amount of heat energy released from the outer surface is suppressed. Further, when the reinforcing plate is provided only on the inner surface of the heat insulating plate, the heat conduction is suppressed by the heat insulating plate, although the inner reinforcing plate is heated by the high-temperature air inside the heat insulating box. Therefore, the heat energy transmitted to the outer surface of the heat insulation box is suppressed, and the amount of heat energy released from the outer surface is also suppressed.
上記第１又は第２の発明において、前記断熱板は、発泡樹脂からなることが好ましい（第３の発明）。この場合は、保温箱の断熱性能が高いものとなる。 In the first or second invention, the heat insulating plate is preferably made of a foamed resin (third invention). In this case, the heat insulation performance of the heat insulation box is high.
第４の発明の糸加熱ローラの保温箱は、前記第１〜第３の何れかの発明において、前記補強板の縁部に、この縁部から前記補強板と直交する方向に延びる金属製の側板が設けられていることを特徴とするものである。 The heat insulation box of the yarn heating roller according to a fourth aspect of the present invention is, in any one of the first to third aspects of the invention, made of a metal that extends from the edge to the direction orthogonal to the reinforcement plate at the edge of the reinforcement plate. A side plate is provided.
補強板の縁部に、金属製の側板が設けられることにより、箱壁部の曲げ剛性が高くなり、保温箱全体の剛性も向上する。あるいは、補強板の厚みを薄くして、保温箱を軽量化することも可能となる。 By providing a metal side plate at the edge of the reinforcing plate, the bending rigidity of the box wall is increased, and the rigidity of the entire heat insulation box is improved. Alternatively, it is possible to reduce the thickness of the reinforcing plate and reduce the weight of the heat insulating box.
第５の発明の糸加熱ローラの保温箱は、前記第４の発明において、前記補強板と前記側板とが一体成形されていることを特徴とするものである。 A heat insulation box for a yarn heating roller according to a fifth invention is characterized in that, in the fourth invention, the reinforcing plate and the side plate are integrally formed.
補強板と側板を溶接等で接合する作業が不要であることから、箱壁部の形成が簡単になる。 Since the work of joining the reinforcing plate and the side plate by welding or the like is unnecessary, the formation of the box wall portion is simplified.
第６の発明の糸加熱ローラの保温箱は、前記第４又は第５の発明において、前記側板は、前記補強板から前記断熱板の積層側に延びていることを特徴とするものである。 In the heat insulation box of the yarn heating roller according to a sixth aspect of the present invention, in the fourth or fifth aspect, the side plate extends from the reinforcing plate to the laminated side of the heat insulating plate.
本発明によれば、補強板に積層された断熱板の側面が側板で覆われることになり、断熱板の側面が側板によって保護される。 According to the present invention, the side surface of the heat insulating plate laminated on the reinforcing plate is covered with the side plate, and the side surface of the heat insulating plate is protected by the side plate.
第７の発明の糸加熱ローラの保温箱は、前記第６の発明において、前記補強板の縁部の、少なくとも、前記補強板の面方向に平行な方向において互いに反対側に位置する２つの部分に、前記側板が設けられ、前記断熱板は、前記側板に挟まれた空間に収納されて、前記補強板に積層されていることを特徴とするものである。 According to a seventh aspect of the present invention, there is provided the heat insulation box of the yarn heating roller according to the sixth aspect, wherein at least two portions of the edge of the reinforcing plate that are opposite to each other in a direction parallel to the surface direction of the reinforcing plate. The side plate is provided, and the heat insulating plate is housed in a space sandwiched between the side plates and laminated on the reinforcing plate.
補強板の縁部の、面方向と平行な方向において反対側に位置する２つの部分に側板がそれぞれ設けられているため、箱壁部の剛性がさらに高くなる。また、側板によって挟まれた空間に断熱板を嵌め込むように収納するだけでよく、断熱板の取付が簡単である。また、側板によって断熱板の補強板に対する位置ズレが規制される。 Since the side plates are respectively provided at two portions of the edge portion of the reinforcing plate located on the opposite sides in the direction parallel to the surface direction, the rigidity of the box wall portion is further increased. Moreover, it is only necessary to store the heat insulating plate so as to fit in the space between the side plates, and the heat insulating plate can be easily attached. Moreover, the position shift with respect to the reinforcement board of a heat insulation board is controlled by the side plate.
第８の発明の糸加熱ローラの保温箱は、前記第７の発明において、前記補強板の前記縁部の全周にわたって、前記側板が連続して設けられて、前記補強板と前記側板により金属箱体が形成され、前記断熱板は、前記金属箱体内の空間に収納されて、前記補強板に積層されていることを特徴とするものである。 In the heat insulation box of the yarn heating roller according to the eighth invention, the side plate is provided continuously over the entire circumference of the edge of the reinforcing plate in the seventh invention, and the reinforcing plate and the side plate are used to form a metal. A box is formed, and the heat insulating plate is housed in a space in the metal box and is laminated on the reinforcing plate.
補強板の縁部の全周にわたって側板が連続して設けられていることから、金属箱体の剛性は高く、それゆえ、箱壁部の剛性もかなり高くなる。また、断熱板の側面全周が側板によって覆われるため、断熱板の側面が確実に保護される。また、側板によって断熱板の補強板に対する位置ズレが確実に規制される。 Since the side plates are continuously provided over the entire periphery of the edge of the reinforcing plate, the rigidity of the metal box is high, and therefore the rigidity of the box wall is also considerably high. Further, since the entire side surface of the heat insulating plate is covered with the side plate, the side surface of the heat insulating plate is reliably protected. Moreover, the position shift with respect to the reinforcement board of a heat insulation board is reliably controlled by the side plate.
第９の発明の糸加熱ローラの保温箱は、前記第１〜第８の何れかの発明において、前記複数の箱壁部のうちの少なくとも１つにおいて、その補強板の前記断熱板とは反対側の面が保温箱の内側を向き、前記保温箱の内面を構成していることを特徴とするものである。 The heat insulation box for the yarn heating roller according to a ninth aspect of the present invention is the heat insulation box according to any one of the first to eighth aspects, wherein at least one of the plurality of box wall portions is opposite to the heat insulating plate of the reinforcing plate. The side surface faces the inside of the heat insulation box and constitutes the inner surface of the heat insulation box.
金属製の補強板は、断熱板と比べて表面硬度が高い。従って、補強板の断熱板とは反対側の面が保温箱の内面を構成していると、糸切れによって加熱ローラに巻き付いた糸が保温箱の内面を叩いたり、糸掛けの際に作業者がサクションガンを保温箱の内面にぶつけたりしても、内面が傷つきにくい。また、金属製の補強板の表面は平滑であるため、油剤や糸屑等の塵、あるいは、汚れが保温箱の内面に付着しても、清掃が容易である。 The metal reinforcing plate has a higher surface hardness than the heat insulating plate. Therefore, if the surface of the reinforcing plate opposite to the heat insulating plate constitutes the inner surface of the heat insulation box, the thread wound around the heating roller due to yarn breakage hits the inner surface of the heat insulation box, Even if the suction gun hits the inner surface of the heat insulation box, the inner surface is not easily damaged. In addition, since the surface of the metal reinforcing plate is smooth, cleaning is easy even if dust such as oil or yarn waste or dirt adheres to the inner surface of the heat insulation box.
第１０の発明の糸加熱ローラの保温箱は、前記第１〜第９の何れかの発明において、前記断熱板の前記補強板とは反対側の面に、断熱補強板が積層されていることを特徴とするものである。 The heat insulation box of the yarn heating roller according to a tenth aspect of the present invention is the heat insulation box according to any one of the first to ninth aspects, wherein a heat insulating reinforcing plate is laminated on a surface of the heat insulating plate opposite to the reinforcing plate. It is characterized by.
この構成では、断熱板の補強板と反対側の面が断熱補強板によって保護される。また、断熱補強板が設けられることによって、剛性の高い補強板と断熱補強板で比較的剛性の低い断熱板を挟み込む、いわゆるサンドイッチ構造となるため、全体の剛性を上げることができる。尚、断熱補強板は、板状の部材によって構成されてもよいし、液状樹脂が塗布された後に硬化した、剛性を有する層であってもよく、その形態は特に限定されない。 In this configuration, the surface of the heat insulating plate opposite to the reinforcing plate is protected by the heat insulating reinforcing plate. Further, by providing the heat insulating reinforcing plate, a so-called sandwich structure in which the heat insulating plate having relatively low rigidity is sandwiched between the reinforcing plate having high rigidity and the heat insulating reinforcing plate, the overall rigidity can be increased. The heat-insulating reinforcing plate may be constituted by a plate-like member, or may be a rigid layer that is cured after the liquid resin is applied, and the form thereof is not particularly limited.
第１１の発明の糸加熱ローラの保温箱の製造方法は、糸を加熱する糸加熱ローラを収容する保温箱の製造方法であって、複数の補強板を接合する組立工程と、前記複数の補強板に断熱板をそれぞれ積層させて、保温箱を構成する複数の箱壁部をそれぞれ形成する箱壁部形成工程と、を備えていることを特徴とするものである。 According to a first aspect of the present invention, there is provided a heat insulation box manufacturing method for a yarn heating roller that heats a yarn. The method for manufacturing the heat insulation box accommodates a plurality of reinforcing plates; And a box wall portion forming step of forming a plurality of box wall portions constituting the heat insulation box by respectively laminating heat insulating plates on the reinforcing plate.
本発明では、複数の金属製の補強板を接合して箱体を組み立てる。また、箱壁部の形成工程では、複数の補強板に断熱板をそれぞれ積層して複数の箱壁部を形成することにより、高い断熱性能の箱壁部を形成することができる。また、断熱板を補強板に積層するだけで、作業が完了する。そのため、不慣れな作業者が作業を行った場合でも、保温箱の断熱性が不均一になりにくい。尚、組立工程と箱壁部形成工程（断熱板の積層）の順番は特に限定されず、何れの工程を先に行ってもよい。 In the present invention, a box is assembled by joining a plurality of metal reinforcing plates. Moreover, in the formation process of a box wall part, a box wall part with high heat insulation performance can be formed by laminating | stacking a heat insulation board on a some reinforcement board, respectively, and forming a some box wall part. Moreover, the operation is completed simply by laminating the heat insulating plate on the reinforcing plate. For this reason, even when an unfamiliar worker performs the work, the heat insulation of the heat insulation box is unlikely to be uneven. In addition, the order of an assembly process and a box wall part formation process (lamination | stacking of a heat insulation board) is not specifically limited, Any process may be performed first.
第１２の発明の糸加熱ローラの保温箱の製造方法は、前記第１１の発明において、前記補強板と直交する方向に延びる側板を、前記補強板の縁部の全周にわたって連続的に設けて、前記補強板と前記側板からなる金属箱体を形成する、金属箱体形成工程をさらに備え、前記組立工程において、複数の前記金属箱体を接合することを特徴とするものである。 Method for producing a heat insulating box of the yarn heating roller of the first and second invention, in the first aspect of the invention, the side plates extending in a direction orthogonal to the reinforcing plate, continuously over the entire circumference of the edge of the reinforcing plate And providing a metal box forming step of forming a metal box composed of the reinforcing plate and the side plate, and joining the plurality of metal boxes in the assembling step.
補強板の縁部の全周にわたって側板が連続して設けられていることから、金属箱体の剛性は高く、それゆえ、箱壁部の剛性もかなり高くなる。 Since the side plates are continuously provided over the entire periphery of the edge of the reinforcing plate, the rigidity of the metal box is high, and therefore the rigidity of the box wall is also considerably high.
第１３の発明の糸加熱ローラの保温箱の製造方法は、前記第１２の発明において、前記箱壁部形成工程において、前記断熱板を、前記金属箱体内の空間に収納して前記補強板に積層することを特徴とするものである。 Method for producing a heat insulating box of the yarn heating roller of the present invention of the first 3, in the first and second invention, in the box wall portion formation step, the reinforcing said heat-insulating plate, are accommodated in the space of the metal box body It is characterized by being laminated on a plate.
補強板と側板により形成された金属箱体内に、断熱板を嵌め込むように収納するだけで断熱板の取付が完了するため、作業が非常に簡単となる。また、補強板の縁部の全周にわたって側板が連続して設けられていることから、この側板によって断熱板の補強板に対する位置ズレが確実に規制される。さらに、断熱板の側面全周が側板によって覆われるため、断熱板の側面が確実に保護される。 Since the installation of the heat insulating plate is completed simply by storing the heat insulating plate so as to fit in the metal box formed by the reinforcing plate and the side plate, the operation becomes very simple. Further, since the side plate is continuously provided over the entire periphery of the edge of the reinforcing plate, the positional displacement of the heat insulating plate with respect to the reinforcing plate is reliably regulated by the side plate. Furthermore, since the entire side surface of the heat insulating plate is covered with the side plate, the side surface of the heat insulating plate is reliably protected.

５つのゴデットローラ１１〜１５は、図示しないモータによってそれぞれ回転駆動される。また、５つのゴデットローラ１１〜１５は、それぞれ、内部にヒータを有する加熱ローラであり、直方体形状の保温箱１６内に収容されている。保温箱１６の右側壁部には、複数の糸Ｙを保温箱１６内に導入するための糸導入口１６ａと、複数の糸Ｙを保温箱１６内から外部へ導出するための糸導出口１６ｂとが形成されている。尚、保温箱１６の詳細構成については後で説明する。 The five godet rollers 11 to 15 are each driven to rotate by a motor (not shown). Each of the five godet rollers 11 to 15 is a heating roller having a heater therein, and is accommodated in a heat insulating box 16 having a rectangular parallelepiped shape. On the right side wall portion of the heat insulation box 16, a yarn introduction port 16a for introducing a plurality of yarns Y into the heat insulation box 16 and a yarn outlet port 16b for extracting the plurality of yarns Y from the heat insulation box 16 to the outside. And are formed. The detailed configuration of the heat insulation box 16 will be described later.
油剤ガイド１０において油剤が付与された複数の糸Ｙは、案内ローラ１７を経て、糸導入口１６ａから保温箱１６内へ案内される。保温箱１６内に導入された複数の糸Ｙは、５つのゴデットローラ１１〜１５に対して、下側のゴデットローラ１１から順に巻掛けられている。 The plurality of yarns Y to which the oil agent is applied in the oil agent guide 10 are guided through the guide roller 17 into the heat retaining box 16 from the yarn introduction port 16a. The plurality of yarns Y introduced into the heat insulation box 16 are wound around the five godet rollers 11 to 15 in order from the lower godet roller 11.
下側３つのゴデットローラ１１〜１３は、複数の糸Ｙを延伸する前に予熱するための加熱ローラであり、それらの加熱温度（ローラ表面温度）は、糸Ｙのガラス転移点以上の温度（例えば、８０℃）に設定されている。一方、上側２つのゴデットローラ１４，１５は、延伸された複数の糸Ｙを熱セットするための加熱ローラであり、それらの加熱温度は、下側３つのゴデットローラ１１〜１３の加熱温度よりも高い温度（例えば、１２０℃）に設定されている。また、上側２つのゴデットローラ１４，１５の糸Ｙ送り速度は、下側３つのゴデットローラ１１〜１３よりも速くなっている。 The lower three godet rollers 11 to 13 are heating rollers for preheating a plurality of yarns Y before drawing, and the heating temperature (roller surface temperature) is a temperature higher than the glass transition point of the yarns Y (for example, , 80 ° C.). On the other hand, the upper two godet rollers 14 and 15 are heating rollers for heat-setting a plurality of stretched yarns Y, and the heating temperatures thereof are higher than the heating temperatures of the lower three godet rollers 11 to 13. (For example, 120 ° C.). Further, the yarn Y feed speeds of the upper two godet rollers 14 and 15 are faster than those of the lower three godet rollers 11 to 13.
保温箱１６内に導入された複数の糸Ｙは、まず、下側３つのゴデットローラ１１〜１３によって送られる間に延伸可能な温度まで予熱される、次に、予熱された複数の糸Ｙは、２つのゴデットローラ１３，１４の間の糸送り速度差によって延伸される。さらに、複数の糸Ｙは、上側２つのゴデットローラ１４，１５によって送られる間により高温に加熱されて、延伸された状態が熱セットされる。上記のようにして延伸された複数の糸Ｙは、糸導出口１６ｂから保温箱１６外に導出され、さらに、案内ローラ１８によって糸巻取装置４に送られる。 The plurality of yarns Y introduced into the heat insulation box 16 are first preheated to a temperature at which they can be stretched while being fed by the lower three godet rollers 11 to 13, and then the plurality of preheated yarns Y are The two godet rollers 13 and 14 are stretched by a difference in yarn feed speed. Further, the plurality of yarns Y are heated to a higher temperature while being sent by the upper two godet rollers 14 and 15, and the stretched state is heat set. The plurality of yarns Y drawn as described above are led out of the heat insulation box 16 from the yarn outlet port 16b and further fed to the yarn winding device 4 by the guide roller 18.
糸巻取装置４は、紡糸延伸装置３の下方に配置されている。この糸巻取装置４は、ボビンホルダ２０と、コンタクトローラ２１等を備えている。ボビンホルダ２０は、図１の紙面垂直方向に延びる長尺な形状を有し、図示しないモータによって回転駆動される。このボビンホルダ２０には、その軸方向に沿って複数のボビン２２が並べて装着される。糸巻取装置４は、ボビンホルダ２０を回転させることによって、複数のボビン２２に複数の糸Ｙを同時に巻取り、複数の巻取パッケージ２３を形成する。コンタクトローラ２１は、複数の巻取パッケージ２３の表面に接触して所定の接圧を付与し、巻取パッケージ２３の形状を整える。 The yarn winding device 4 is disposed below the spinning drawing device 3. The yarn winding device 4 includes a bobbin holder 20, a contact roller 21, and the like. The bobbin holder 20 has a long shape extending in the direction perpendicular to the plane of FIG. 1 and is driven to rotate by a motor (not shown). A plurality of bobbins 22 are attached to the bobbin holder 20 along the axial direction. The yarn winding device 4 rotates a bobbin holder 20 to simultaneously wind a plurality of yarns Y around a plurality of bobbins 22 to form a plurality of winding packages 23. The contact roller 21 contacts the surface of the plurality of winding packages 23 and applies a predetermined contact pressure to adjust the shape of the winding package 23.
次に、５つのゴデットローラ１１〜１５を収容する保温箱１６について詳細に説明する。図２は、保温箱の斜視図である。図３は、保温箱の１つの箱壁部の分解斜視図である。図４は、扉部を閉じた状態における保温箱の縦断面図である。尚、図２に示すように、保温箱１６の前後、左右、及び、上下の各方向を定義し、以下、適宜これらの方向語を用いて説明する。 Next, the heat insulation box 16 that houses the five godet rollers 11 to 15 will be described in detail. FIG. 2 is a perspective view of the heat insulation box. FIG. 3 is an exploded perspective view of one box wall portion of the heat insulation box. FIG. 4 is a longitudinal sectional view of the heat insulation box in a state where the door portion is closed. In addition, as shown in FIG. 2, the front / rear, left / right, and upper / lower directions of the heat insulation box 16 are defined, and will be described below using these direction words as appropriate.
図２〜図４に示すように、保温箱１６は、６つの箱壁部３０が連結されることによって、直方体形状に形成されている。６つの箱壁部３０は、上壁部３０ａ、下壁部３０ｂ、左側壁部３０ｃ、右側壁部３０ｄ、後壁部３０ｅと、左側壁部３０ｃの前端部にヒンジ等によって回動自在に取り付けられた扉部３０ｆである。右側壁部３０ｄの下端部及び上端部には、それぞれ糸導入口１６ａ及び糸導出口１６ｂとなる、２つの切り欠きが形成されている。 As shown in FIGS. 2 to 4, the heat insulation box 16 is formed in a rectangular parallelepiped shape by connecting six box wall portions 30. The six box wall portions 30 are rotatably attached to the front end portion of the upper wall portion 30a, the lower wall portion 30b, the left wall portion 30c, the right wall portion 30d, the rear wall portion 30e, and the left wall portion 30c by a hinge or the like. Door portion 30f. Two notches are formed at the lower end and the upper end of the right side wall portion 30d, which become the yarn introduction port 16a and the yarn outlet port 16b, respectively.
図３に示すように、６つの箱壁部３０は、それぞれ、金属箱体３１と、断熱板３２と、断熱補強板３３とを有するパネルである。金属箱体３１は、ステンレス鋼等の金属板から形成された、内部に断熱板３２を収容可能な矩形箱状の構造体である。金属箱体３１は、プレス加工によって一体成形された補強板３４と側板３５とを有する。より詳細には、金属箱体３１の底部となる、矩形状の補強板３４の縁部に、その面方向と直交する方向で、且つ、断熱板３２が積層される側（図３の上側）に延びる側板３５が設けられている。この側板３５は、補強板３４の縁部の全周にわたって連続的に形成されている。 As shown in FIG. 3, the six box wall portions 30 are panels each having a metal box body 31, a heat insulating plate 32, and a heat insulating reinforcing plate 33. The metal box 31 is a rectangular box-shaped structure that is formed of a metal plate such as stainless steel and can accommodate the heat insulating plate 32 therein. The metal box 31 includes a reinforcing plate 34 and a side plate 35 that are integrally formed by press working. More specifically, on the edge of the rectangular reinforcing plate 34, which is the bottom of the metal box 31, in the direction orthogonal to the surface direction and the side on which the heat insulating plate 32 is laminated (upper side in FIG. 3) A side plate 35 extending in the direction is provided. The side plate 35 is continuously formed over the entire periphery of the edge of the reinforcing plate 34.
断熱板３２は、金属よりも熱伝導率の低い材料で形成されている。本実施形態では、具体的には、発泡樹脂（合成樹脂発泡体）で形成されている。保温箱１６内に収容されるゴデットローラ１１〜１５の加熱温度が、例えば、８０〜１２０℃の温度に設定されることから、保温箱１６を構成する断熱板３２には、その設定温度以上の耐熱性が要求されるが、耐熱性が満たない場合は補強板３４と側板３５の、断熱板３２と接触する面に断熱塗料が塗布されてもよい。また、保温箱１６から外部への放熱を抑えるために、当然ながら、断熱板３２の断熱性もできるだけ高いことが好ましい。 The heat insulating plate 32 is formed of a material having a lower thermal conductivity than metal. In this embodiment, specifically, it is formed with a foamed resin (synthetic resin foam). Since the heating temperature of the godet rollers 11 to 15 accommodated in the heat insulation box 16 is set to, for example, a temperature of 80 to 120 ° C., the heat insulating plate 32 constituting the heat insulation box 16 has a heat resistance higher than the set temperature. However, if the heat resistance is not sufficient, a heat insulating paint may be applied to the surfaces of the reinforcing plate 34 and the side plate 35 that are in contact with the heat insulating plate 32. Moreover, in order to suppress the heat radiation from the heat insulating box 16 to the outside, it is naturally preferable that the heat insulating property of the heat insulating plate 32 is as high as possible.
このような断熱板３２に好適に使用できる発泡樹脂としては、耐熱性の面から熱硬化性樹脂の発泡材料が望ましく、例えば、発泡フェノール樹脂（フェノールフォーム）を挙げることができる。従来の保温箱で使用されているロックウールの熱伝達率が０．０５Ｗ／（ｍ・Ｋ）に対し、上記発泡フェノール樹脂（ＪＩＳ Ａ ９５１１フェノールフォーム）の熱伝達率は０．０２２Ｗ／（ｍ・Ｋ）である。また、コスト面から、上記フェノールフォームに替えて、これよりも断熱性能に劣る材料を使用してもよい。その他に使用可能な材料としては、繊維系断熱材である、密度１６ｋｇ／ｍ３以上のグラスウールボード（熱伝達率０．０４５Ｗ／（ｍ・Ｋ））、炭化コルクボード（同０．０４１Ｗ／（ｍ・Ｋ））、樹脂断熱材である、エポキシ樹脂（同０．１９Ｗ／（ｍ・Ｋ））、ベークライト（同０．２１Ｗ／（ｍ・Ｋ））、真空断熱材（同０．００５２Ｗ／（ｍ・Ｋ））等を挙げることができる。断熱板３２は、予め、金属箱体３１の補強板３４とほぼ同じ大きさにカットされた上で、金属箱体３１内に嵌め込まれるように収納され、補強板３４に積層されている。また、補強板３４の縁部全周に設けられた側板３５によって、断熱板３２の補強板３４に対する位置ズレが規制される。尚、位置ズレを確実に防止するために、断熱板３２が、金属箱体３１に収容された状態で、金属箱体３１に接着剤等で固定されてもよい。 As the foamed resin that can be suitably used for such a heat insulating plate 32, a foamed material of a thermosetting resin is desirable from the viewpoint of heat resistance, and examples thereof include a foamed phenol resin (phenol foam). The heat transfer coefficient of rock wool used in conventional heat insulation boxes is 0.05 W / (m · K), whereas the heat transfer coefficient of the above-mentioned foamed phenol resin (JIS A 9511 phenol foam) is 0.022 W / (m・ K). Further, in terms of cost, a material having inferior heat insulation performance may be used instead of the phenol foam. Other materials that can be used are fiber-based heat insulating materials such as glass wool board with a density of 16 kg / m 3 or more (heat transfer coefficient 0.045 W / (m · K)), carbonized cork board (0.041 W / (m・ K)), epoxy resin (0.19 W / (m · K)), bakelite (0.21 W / (m · K)), vacuum heat insulating material (0.0052 W / ( m · K)) and the like. The heat insulating plate 32 is cut in advance to be approximately the same size as the reinforcing plate 34 of the metal box 31, accommodated so as to be fitted into the metal box 31, and laminated on the reinforcing plate 34. Further, the position shift of the heat insulating plate 32 with respect to the reinforcing plate 34 is regulated by the side plate 35 provided on the entire periphery of the edge of the reinforcing plate 34. In order to surely prevent displacement, the heat insulating plate 32 may be fixed to the metal box 31 with an adhesive or the like while being accommodated in the metal box 31.
断熱補強板３３は、断熱板３２の表面（補強板３４と反対側の面）に、断熱板３２の表面全域を覆うように積層されている。断熱補強板３３は、断熱板３２を保護する目的から、断熱板３２に比べ断熱性は多少劣っても、剛性や強度が高い材料で形成される。一方で、保温性の目的から、金属箱体３１の補強板３４よりは断熱性に優れた材料で形成される。例えば、フェノール樹脂等の熱硬化性樹脂で形成される。図３に示すように、断熱板３２と断熱補強板３３の間には、さらに、シリコン等の液状のコーティング剤を塗布することにより、被覆層３６が形成されてもよい。被覆層３６のコーティング剤が、金属箱体３１、断熱板３２、及び、断熱補強板３３の間に存在する隙間に染み渡ることで、それらの隙間が塞がれ、外部からの油剤や異物の浸入を防ぎ、断熱板３２の変質を防ぐことができる。 The heat insulating reinforcing plate 33 is laminated on the surface of the heat insulating plate 32 (the surface on the side opposite to the reinforcing plate 34) so as to cover the entire surface of the heat insulating plate 32. For the purpose of protecting the heat insulating plate 32, the heat insulating reinforcing plate 33 is formed of a material having high rigidity and strength even though the heat insulating property is somewhat inferior to that of the heat insulating plate 32. On the other hand, for the purpose of heat retention, the metal box 31 is formed of a material having better heat insulation than the reinforcing plate 34. For example, it is formed of a thermosetting resin such as a phenol resin. As shown in FIG. 3, a coating layer 36 may be formed between the heat insulating plate 32 and the heat insulating reinforcing plate 33 by applying a liquid coating agent such as silicon. The coating agent of the covering layer 36 penetrates into the gaps existing between the metal box 31, the heat insulating plate 32, and the heat insulating reinforcing plate 33, so that the gaps are closed and intrusion of oil or foreign matters from the outside. It is possible to prevent deterioration of the heat insulating plate 32.
図２、図４に示すように、扉部３０ｆを除く５つの箱壁部３０ａ〜３０ｅは、金属箱体３１の補強板３４の、断熱板３２と反対側の面が、保温箱１６の内側に向くように連結されている。これにより、５つの箱壁部３０ａ〜３０ｅにおいては、補強板３４の断熱板３２と反対側の面が、保温箱１６の内面をそれぞれ構成しており、断熱板３２が補強板３４よりも外側に位置している。この構成により、５つの箱壁部３０ａ〜３０ｅの外面の温度はそれほど高くならない。 As shown in FIGS. 2 and 4, the five box wall portions 30 a to 30 e except for the door portion 30 f are such that the reinforcing plate 34 of the metal box 31 has a surface opposite to the heat insulating plate 32 inside the heat insulation box 16. It is connected so that it may face. Thereby, in five box wall parts 30a-30e, the surface on the opposite side to the heat insulation board 32 of the reinforcement board 34 has each comprised the inner surface of the heat insulation box 16, and the heat insulation board 32 is outside the reinforcement board 34. Is located. With this configuration, the temperatures of the outer surfaces of the five box wall portions 30a to 30e are not so high.
一方、扉部３０ｆについては、金属箱体３１の補強板３４は断熱板３２よりも外側に位置しており、補強板３４の断熱板３２と反対側の面は、保温箱１６の内側に向いていない。扉部３０ｆのみ上記の配置となっている理由は、次の通りである。扉部３０ｆの外面には、取っ手３７等の構造物が取り付けられるが、このような構造物を支えることのできるのに十分な剛性を、扉部３０ｆの外面側に確保するためである。即ち、図４に示すように、取っ手３７を、断熱板３２よりも外側に配置された、剛性の高い補強板３４にボルト等で簡単に取り付けることができるようになる。 On the other hand, with respect to the door portion 30 f, the reinforcing plate 34 of the metal box 31 is positioned outside the heat insulating plate 32, and the surface of the reinforcing plate 34 opposite to the heat insulating plate 32 faces the inside of the heat insulating box 16. Not. The reason why only the door portion 30f is arranged as described above is as follows. A structure such as a handle 37 is attached to the outer surface of the door portion 30f, but this is to ensure sufficient rigidity on the outer surface side of the door portion 30f to support such a structure. That is, as shown in FIG. 4, the handle 37 can be easily attached with a bolt or the like to the highly rigid reinforcing plate 34 disposed outside the heat insulating plate 32.
尚、取っ手３７は扉部３０ｆの側面に取り付けられてもよい。その場合は、図４において、金属箱体３１の補強板３４が保温箱１６の内側を向いた構成であっても構わない。しかし、特に、以下のような構成では、取っ手３７を扉部３０ｆの前面に取り付ける場合でも側面に取り付ける場合でも、金属箱体３１の補強板３４は、保温箱１６の外側を向いている必要がある。図５は、別形状の扉部を有する保温箱の縦断面図である。図５の構成では、糸掛けの作業性を向上させる目的で、ゴデットローラ１１〜１５（図５には、３つのローラ１１，１３，１５のみ図示）の先端部が、上壁部３０ａ、下壁部３０ｂ、左側壁部３０ｃ、右側壁部３０ｄの前面から突出している。この場合、扉部３０ｆの内側に、ゴデットローラ１１〜１５の先端部との干渉を避けるための空間を確保する必要がある。そこで、扉部３０ｆは、Ｕ字状の断面形状を有するものとなっている。このような扉部３０ｆでは、その前面又は側面に取っ手３７を取り付けるためには、金属箱体３１の補強板３４は断熱板３２よりも外側に位置している必要がある。 The handle 37 may be attached to the side surface of the door portion 30f. In that case, the configuration may be such that the reinforcing plate 34 of the metal box 31 faces the inside of the heat insulating box 16 in FIG. However, in particular, in the following configuration, the reinforcing plate 34 of the metal box 31 needs to face the outside of the heat insulating box 16 regardless of whether the handle 37 is attached to the front surface or the side surface of the door portion 30f. is there. FIG. 5 is a vertical cross-sectional view of a heat insulation box having a door with another shape. In the configuration of FIG. 5, for the purpose of improving the threading workability, the tip portions of the godet rollers 11 to 15 (only three rollers 11, 13, and 15 are shown in FIG. 5) are the upper wall portion 30 a and the lower wall portion. It protrudes from the front surface of the part 30b, the left side wall part 30c, and the right side wall part 30d. In this case, it is necessary to secure a space for avoiding interference with the tip portions of the godet rollers 11 to 15 inside the door portion 30f. Therefore, the door portion 30f has a U-shaped cross-sectional shape. In such a door portion 30f, the reinforcing plate 34 of the metal box 31 needs to be positioned outside the heat insulating plate 32 in order to attach the handle 37 to the front surface or side surface thereof.
また、金属製の補強板３４は断熱板３２があることで、火傷を負うほどの高温にはならないが、扉部３０ｆにおいてこの補強板３４が外側に露出していると、オペレータが扉部３０ｆを開閉操作する際に、常温よりも高い温度の補強板３４に直接手が触れてしまう虞がある。そこで、図４、図５に示すように、扉部３０ｆにおいては、金属箱体３１の外面にも、断熱層３８が積層されている。尚、この断熱層３８は、断熱板３２に積層される断熱補強板３３と材質等が同じものであってもよいし、異なるものであってもよい。また、扉部３０ｆについては、保温箱１６の内側に断熱板３２が露出する。そこで、糸屑や切れた走行糸による断熱板３２の破損を防ぐために、図示しない保護板が、断熱板３２の、保温箱１６の内側の面に積層されていてもよい。 Further, the metal reinforcing plate 34 does not reach a high temperature so as to cause burns due to the presence of the heat insulating plate 32. However, if the reinforcing plate 34 is exposed to the outside in the door portion 30f, the operator can set the door portion 30f. There is a risk that the hand may directly touch the reinforcing plate 34 having a temperature higher than the normal temperature when opening and closing the door. Therefore, as shown in FIGS. 4 and 5, the heat insulating layer 38 is also laminated on the outer surface of the metal box 31 in the door portion 30 f. The heat insulating layer 38 may be the same as or different from the heat insulating reinforcing plate 33 laminated on the heat insulating plate 32. Further, the heat insulating plate 32 is exposed inside the heat insulating box 16 for the door portion 30f. Therefore, a protection plate (not shown) may be laminated on the inner surface of the heat insulating box 16 of the heat insulating plate 32 in order to prevent the heat insulating plate 32 from being damaged by yarn waste or broken running yarn.
図４に示すように、保温箱１６は、後壁部３０ｅにおいて、紡糸延伸装置３の各構成部を支持する機台４０に取り付けられている。具体的には、後壁部３０ｅの補強板３４と機台４０との間に樹脂製のスペーサ４２を介在させ、複数のボルト４１を通すことによって、保温箱１６が機台に固定されている。尚、保温箱１６からボルト４１を介しての外部放熱を極力抑えるために、ボルト４１は、金属製のものではなく、樹脂製のものであることが好ましい。 As shown in FIG. 4, the heat retaining box 16 is attached to a machine base 40 that supports each component of the spinning stretcher 3 in the rear wall 30 e. Specifically, the heat insulating box 16 is fixed to the machine base by interposing a resin spacer 42 between the reinforcing plate 34 of the rear wall 30e and the machine base 40 and passing a plurality of bolts 41. . In addition, in order to suppress external heat radiation from the heat insulation box 16 through the bolt 41 as much as possible, the bolt 41 is preferably not made of metal but made of resin.
次に、上記の保温箱１６の製造方法について説明する。保温箱１６の製造工程は、大別すると、６つの金属箱体３１をそれぞれ形成する工程（金属箱体形成工程）と、６つの金属箱体３１を接合する工程（組立工程）と、６つの金属箱体３１へ断熱板３２等を積層させて箱壁部３０を形成する工程（箱壁部形成工程）とを備える。 Next, the manufacturing method of said heat retention box 16 is demonstrated. The manufacturing process of the heat insulation box 16 is roughly divided into a process of forming six metal boxes 31 (metal box forming process), a process of joining the six metal boxes 31 (assembly process), and six processes. A step of forming the box wall portion 30 by laminating the heat insulating plate 32 and the like on the metal box body 31 (box wall portion forming step).
尚、これらの工程の順番としては、以下の２通りが考えられるが、何れの方法も実施可能である。作業性等を考慮して適宜選択すればよい。
（１）金属箱体形成工程→組立工程（６つの金属箱体３１を接合）→箱壁部形成工程（金属箱体３１に断熱板３２等を積層）
（２）金属箱体形成工程→箱壁部形成工程→組立工程
In addition, as the order of these steps, the following two types are conceivable, but either method can be implemented. What is necessary is just to select suitably in consideration of workability | operativity etc.
(1) Metal box forming process → Assembly process (6 metal box bodies 31 are joined) → Box wall forming process (insulating plate 32 etc. are laminated on metal box 31)
(2) Metal box forming process → Box wall forming process → Assembly process
（金属箱体形成工程）
まず、１枚の金属板にプレス加工を施して、補強板３４と側板３５とを一体成形し、金属箱体３１を作製する。この要領で６つの金属箱体３１をそれぞれ形成する。
(Metal box forming process)
First, a single metal plate is subjected to press work, and the reinforcing plate 34 and the side plate 35 are integrally formed to produce the metal box 31. In this way, six metal boxes 31 are formed.
（組立工程）
組立工程では６つの金属箱体３１を接合する。接合方法は、６つの金属箱体３１同士を溶接によって接合してもよいが、ボルト等の連結具によって接合してもよい。ここで、図４に示すように、６つの箱壁部３０のうちの扉部３０ｆを除く５つの箱壁部３０ａ〜３０ｅに対応する金属箱体３１については、それらの補強板３４の断熱板３２と反対側の面が、保温箱１６の内側を向くような姿勢にして連結する。一方、扉部３０ｆについては、閉じた状態で、補強板３４が断熱板３２よりも外側に位置するような姿勢で、左側壁部３０ｃに対応する金属箱体３１にヒンジ等で回転自在に接合する。
(Assembly process)
In the assembly process, six metal boxes 31 are joined. As a joining method, the six metal box bodies 31 may be joined by welding, but may be joined by a connecting tool such as a bolt. Here, as shown in FIG. 4, about the metal box 31 corresponding to five box wall parts 30a-30e except the door part 30f among the six box wall parts 30, the heat insulation board of those reinforcement boards 34 is shown. The surface opposite to 32 is connected in such a posture as to face the inside of the heat insulation box 16. On the other hand, the door portion 30f is in a closed state and is rotatably joined to the metal box 31 corresponding to the left side wall portion 30c by a hinge or the like in such a posture that the reinforcing plate 34 is positioned outside the heat insulating plate 32. To do.
（箱壁部形成工程）
予め、補強板３４とほぼ同じ平面積となる大きさにカットされた断熱板３２を、金属箱体３１内に嵌め込むようにして収納し、補強板３４に積層接着させる。次に、断熱板３２の上にシリコン等のコーティング剤を塗布して被覆層３６を形成する。最後に、被覆層３６の表面（補強板３４と反対側の面）にフェノール樹脂等からなる断熱補強板３３を積層する。断熱補強板３３の形成は、樹脂プレートを被覆層３６に積層させてもよいし、液状の硬化性樹脂を被覆層３６の表面に塗布してから硬化させてもよい。以上の作業を繰り返して６つの箱壁部３０をそれぞれ形成する。但し、扉部３０ｆについては、補強板３４の、断熱板３２の積層側と反対側の面に断熱補強板３３を積層させるという作業を、特別に行う。
(Box wall forming process)
A heat insulating plate 32 that has been cut into a size that is approximately the same plane area as the reinforcing plate 34 is accommodated in the metal box 31 so as to be laminated and bonded to the reinforcing plate 34. Next, a coating agent such as silicon is applied on the heat insulating plate 32 to form the coating layer 36. Finally, a heat insulating reinforcing plate 33 made of phenol resin or the like is laminated on the surface of the coating layer 36 (the surface opposite to the reinforcing plate 34). The heat insulating reinforcing plate 33 may be formed by laminating a resin plate on the coating layer 36 or by applying a liquid curable resin on the surface of the coating layer 36 and then curing the resin plate. The above operations are repeated to form six box wall portions 30 respectively. However, with respect to the door portion 30f, the operation of laminating the heat insulating reinforcing plate 33 on the surface of the reinforcing plate 34 on the side opposite to the layer side of the heat insulating plate 32 is specially performed.
以上説明した本実施形態の保温箱１６によれば、次のような効果が得られる。
（１）６つの箱壁部３０のそれぞれが、発泡樹脂からなる断熱板３２と金属製の補強板３４とが積層されてなるパネル構造を有する。それ故、断熱板３２を補強板３４に積層することで箱壁部３０となる１つのパネルを簡単に形成できる。さらに、保温箱１６の骨格形状が、６つの金属箱体３１を接合するだけで完成することから、保温箱１６の組立が非常に容易である。また、発泡樹脂からなる断熱板３２の断熱性は、従来使用されていたロックウールなどと比べると数倍高い。従って、各箱壁部３０の断熱性が高くなり、ひいては、保温箱１６全体の断熱性能も向上する。さらに、所定サイズの断熱板３２を補強板３４に積層するだけで断熱板３２の取付が完了するので、不慣れな作業者が作業を行う場合でも、保温箱１６の断熱性が不均一になりにくい。
According to the heat insulation box 16 of the present embodiment described above, the following effects can be obtained.
(1) Each of the six box wall portions 30 has a panel structure in which a heat insulating plate 32 made of foamed resin and a metal reinforcing plate 34 are laminated. Therefore, by laminating the heat insulating plate 32 on the reinforcing plate 34, one panel that becomes the box wall 30 can be easily formed. Furthermore, since the skeleton shape of the heat insulation box 16 is completed simply by joining the six metal box bodies 31, the heat insulation box 16 can be assembled very easily. Moreover, the heat insulation property of the heat insulating plate 32 made of foamed resin is several times higher than that of conventionally used rock wool or the like. Therefore, the heat insulation of each box wall part 30 becomes high, and the heat insulation performance of the heat insulation box 16 as a whole is improved. Furthermore, since the installation of the heat insulating plate 32 is completed simply by laminating the heat insulating plate 32 of a predetermined size on the reinforcing plate 34, even when an unskilled worker performs the work, the heat insulating property of the heat insulating box 16 is unlikely to be uneven. .
（２）６つの箱壁部３０のうち、箱壁部３０ａ〜３０ｅでは、熱伝導率が高い金属の補強板３４が、断熱板３２の内面にしか積層されていない。また、扉部３０ｆでは、金属の補強板３４が、断熱板３２の外面にしか積層されていない。従って、６つの箱壁部３０のそれぞれにおいて、補強板３４を伝わって内部の熱が外部へ逃げる熱量を抑制することができる。即ち、断熱板３２の外面にしか補強板３４がない場合は、保温箱１６の内部の高温の空気が金属の補強板３４には直接触れず、断熱板３２を介してのみ外面の補強板３４に熱が伝わるので、外面の補強板３４が高温になることがなく、外面から放出される熱エネルギーの量が抑制される。また、断熱板３２の内面にしか補強板３４がない場合は、保温箱１６の内部の高温の空気で内面の補強板３４は高温になるものの、断熱板３２で熱伝導が抑えられる。従って、保温箱１６の外面に伝わる熱エネルギーが抑えられ、外面から放出される熱エネルギーの量も抑制される。 (2) Of the six box wall portions 30, in the box wall portions 30 a to 30 e, the metal reinforcing plate 34 having high thermal conductivity is laminated only on the inner surface of the heat insulating plate 32. Further, in the door portion 30 f, the metal reinforcing plate 34 is laminated only on the outer surface of the heat insulating plate 32. Therefore, in each of the six box wall portions 30, it is possible to suppress the amount of heat that is transmitted through the reinforcing plate 34 and the internal heat escapes to the outside. That is, when the reinforcing plate 34 is provided only on the outer surface of the heat insulating plate 32, the high-temperature air inside the heat insulating box 16 does not directly touch the metal reinforcing plate 34, and the outer reinforcing plate 34 only through the heat insulating plate 32. Since heat is transmitted to the outer surface, the reinforcing plate 34 on the outer surface does not become high temperature, and the amount of heat energy released from the outer surface is suppressed. Further, when the reinforcing plate 34 is provided only on the inner surface of the heat insulating plate 32, the heat conduction is suppressed by the heat insulating plate 32, although the inner reinforcing plate 34 is heated by the high-temperature air inside the heat insulating box 16. Therefore, the heat energy transmitted to the outer surface of the heat insulation box 16 is suppressed, and the amount of heat energy released from the outer surface is also suppressed.
（３）補強板３４の縁部に側板３５が設けられているため、箱壁部３０の曲げ剛性が高くなる。特に、本実施形態では、側板３５が、補強板３４の縁部全周にわたって連続的に設けられていることから、金属箱体３１の剛性は高く、それゆえ箱壁部３０の剛性もかなり高くなる。このように箱壁部３０の剛性が高くなることで、保温箱１６全体の剛性も向上する。あるいは、金属製の補強板３４（金属箱体３１）の厚みを薄くして、保温箱１６を軽量化することも可能となる。また、側板３５は、補強板３４から断熱板３２の積層側に延びているために、断熱板３２の側面が側板３５に覆われる。特に、補強板３４の縁部全周に側板３５が設けられていることで、断熱板３２の側面全周が側板３５で覆われるため、断熱板３２の側面が確実に保護される。 (3) Since the side plate 35 is provided at the edge of the reinforcing plate 34, the bending rigidity of the box wall portion 30 is increased. In particular, in the present embodiment, since the side plate 35 is continuously provided over the entire periphery of the edge of the reinforcing plate 34, the rigidity of the metal box 31 is high, and hence the rigidity of the box wall 30 is also considerably high. Become. Thus, the rigidity of the heat insulation box 16 whole also improves because the rigidity of the box wall part 30 becomes high. Alternatively, it is possible to reduce the thickness of the metal reinforcing plate 34 (metal box 31) and reduce the weight of the heat insulating box 16. Further, since the side plate 35 extends from the reinforcing plate 34 to the laminated side of the heat insulating plate 32, the side surface of the heat insulating plate 32 is covered with the side plate 35. In particular, since the side plate 35 is provided on the entire periphery of the edge of the reinforcing plate 34, the entire side surface of the heat insulating plate 32 is covered with the side plate 35, so that the side surface of the heat insulating plate 32 is reliably protected.
また、断熱板３２を、金属箱体３１の側板３５内に断熱板３２を嵌め込むように収納するだけで、断熱板３２を簡単に取り付けることができる。また、側板３５によって断熱板３２の補強板３４に対する位置ズレが確実に規制される。 Moreover, the heat insulation board 32 can be easily attached only by accommodating the heat insulation board 32 so that the heat insulation board 32 may be fitted in the side plate 35 of the metal box 31. Further, the positional displacement of the heat insulating plate 32 with respect to the reinforcing plate 34 is reliably regulated by the side plate 35.
さらに、補強板３４と側板３５とが、プレス加工により一体成形されているため、補強板３４と側板３５を溶接等で接合する作業が不要であり、箱壁部３０の形成がさらに簡単になる。 Further, since the reinforcing plate 34 and the side plate 35 are integrally formed by pressing, the work of joining the reinforcing plate 34 and the side plate 35 by welding or the like is not necessary, and the formation of the box wall portion 30 is further simplified. .
（４）断熱板３２の、補強板３４とは反対側の面に、断熱補強板３３が積層されているため、断熱板３２の補強板３４と反対側の面が断熱補強板３３によって保護される。また、断熱補強板３３が設けられることによって、剛性の高い補強板３４と断熱補強板３３で比較的剛性の低い断熱板３２を挟み込む、いわゆるサンドイッチ構造となるため、全体の剛性を上げることができる。尚、断熱補強板３３は、板状の部材によって構成されてもよいし、液状樹脂が塗布された後に硬化した、剛性を有する層であってもよく、その形態は特に限定されない。 (4) Since the heat insulating reinforcing plate 33 is laminated on the surface of the heat insulating plate 32 opposite to the reinforcing plate 34, the surface of the heat insulating plate 32 opposite to the reinforcing plate 34 is protected by the heat insulating reinforcing plate 33. The Further, since the heat insulating reinforcing plate 33 is provided, a so-called sandwich structure in which the heat insulating plate 32 having relatively low rigidity is sandwiched between the high rigidity reinforcing plate 34 and the heat insulating reinforcing plate 33 can increase the overall rigidity. . The heat insulating reinforcing plate 33 may be constituted by a plate-like member, or may be a rigid layer that is cured after the liquid resin is applied, and the form thereof is not particularly limited.
（５）本実施形態では、扉部３０ｆを除く５つの箱壁部３０ａ〜３０ｅのそれぞれにおいて、その補強板３４の断熱板３２とは反対側の面が保温箱１６の内側を向いて、保温箱１６の内面を構成している。金属製の補強板３４は、発泡樹脂の断熱板３２や断熱補強板３３と比べて表面硬度が高い。糸切れによってゴデットローラ１１〜１５に巻き付いた糸Ｙが保温箱１６の内面を叩いたり、糸掛けの際に作業者がサクションガンを保温箱１６の内面にぶつけたりしても、内面が傷つきにくい。また、金属製の補強板３４の表面は平滑であるため、糸Ｙから分離した油剤や糸屑等の塵、あるいは、汚れが保温箱１６の内面に付着しても、清掃が容易である。尚、ゴデットローラ１１〜１５の汚れが激しい場合は、アルカリ性の洗浄液や大量の水で清掃されることがある。そのため、保温箱１６の内面は清掃し易くかつ腐食し難いステンレス鋼板で構成されることが望ましい。 (5) In this embodiment, in each of the five box wall portions 30a to 30e excluding the door portion 30f, the surface opposite to the heat insulating plate 32 of the reinforcing plate 34 faces the inner side of the heat insulating box 16, so The inner surface of the box 16 is configured. The metal reinforcing plate 34 has a higher surface hardness than the foamed resin heat insulating plate 32 and the heat insulating reinforcing plate 33. Even if the yarn Y wound around the godet rollers 11 to 15 due to yarn breakage hits the inner surface of the heat insulation box 16 or an operator hits the suction gun against the inner surface of the heat insulation box 16 when threading, the inner surface is not easily damaged. Further, since the surface of the metal reinforcing plate 34 is smooth, cleaning is easy even if dust such as oil agent or yarn waste separated from the yarn Y or dirt adheres to the inner surface of the heat insulating box 16. If the godet rollers 11 to 15 are heavily soiled, they may be cleaned with an alkaline cleaning liquid or a large amount of water. Therefore, it is desirable that the inner surface of the heat insulation box 16 is made of a stainless steel plate that is easy to clean and hardly corrodes.
次に、前記実施形態に種々の変更を加えた変更形態について説明する。但し、前記実施形態と同様の構成を有するものについては、同じ符号を付して適宜その説明を省略する。 Next, modified embodiments in which various modifications are made to the embodiment will be described. However, components having the same configuration as in the above embodiment are given the same reference numerals and description thereof is omitted as appropriate.
１］箱壁部３０の構成は、例えば、以下のように変更可能である。
前記実施形態では、各箱壁部３０の補強板３４の縁部全周にわたって連続的に側板３５が設けられていたが、図６（ａ）に示すように、補強板３４の縁部に沿って、複数の側板３５が互いに間隔を空けて設けられていてもよい。
1] The configuration of the box wall portion 30 can be changed as follows, for example.
In the above embodiment, the side plate 35 is continuously provided over the entire periphery of the edge of the reinforcing plate 34 of each box wall 30, but as shown in FIG. 6A, along the edge of the reinforcing plate 34. Thus, the plurality of side plates 35 may be provided at intervals.
また、補強板３４の縁部全周に側板３５が設けられていなくてもよい。この場合でも、箱壁部３０の曲げ剛性を確保するためには、補強体３４の縁部の、補強板３４の面方向と平行な方向において互いに反対側に位置する２つの部分に、側板３５がそれぞれ設けられていることが好ましい。例えば、図６（ｂ）には、補強板３４の縁部のうちの短辺方向において互いに反対側に位置する２つの部分、即ち、補強板３４の２つの長辺部分に、２つの側板３５がそれぞれ設けられている。この形態においても、断熱板３２を、２つの側板３５によって区切られた空間に断熱板３２を嵌め込むように収納するだけでその取付が完了するため、断熱板３２の取付が簡単である。また、２つの側板３５によって断熱板３２の補強板３４に対する、補強板３４の短辺方向における位置ズレが規制される。 Further, the side plate 35 may not be provided on the entire periphery of the edge of the reinforcing plate 34. Even in this case, in order to ensure the bending rigidity of the box wall portion 30, the side plate 35 is provided on two portions of the edge of the reinforcing body 34 that are located on opposite sides in the direction parallel to the surface direction of the reinforcing plate 34. Are preferably provided. For example, in FIG. 6B, two side plates 35 are provided on two portions of the edges of the reinforcing plate 34 that are located on opposite sides in the short side direction, that is, on two long side portions of the reinforcing plate 34. Are provided. Also in this embodiment, the heat insulating plate 32 can be easily attached because the heat insulating plate 32 is installed by simply storing the heat insulating plate 32 so that the heat insulating plate 32 is fitted in the space defined by the two side plates 35. Further, the positional displacement in the short side direction of the reinforcing plate 34 with respect to the reinforcing plate 34 of the heat insulating plate 32 is regulated by the two side plates 35.
また、図２では、６つの箱壁部３０のうち、左側壁部３０ｃ、右側壁部３０ｄ、及び、後壁部３０ｅの３つの箱壁部３０では、それぞれの一部の側部が、上壁部３０ａ及び下壁部３０ｂに当接している。このような側部においては、断熱板３２が側板３５によって覆われている必要はあまりない。つまり、図２のような保温箱１６であれば、特に、左側壁部３０ｃ、右側壁部３０ｄ、及び、後壁部３０ｅの３つの箱壁部３０に、図６（ｂ）の構成を好適に採用できる。 In FIG. 2, among the six box wall portions 30, in the three box wall portions 30 of the left wall portion 30 c, the right wall portion 30 d, and the rear wall portion 30 e, some of the side portions are It abuts against the wall 30a and the lower wall 30b. In such a side portion, it is not necessary that the heat insulating plate 32 is covered with the side plate 35. That is, in the case of the heat insulation box 16 as shown in FIG. 2, the configuration of FIG. 6B is particularly suitable for the three box wall portions 30 of the left wall portion 30c, the right wall portion 30d, and the rear wall portion 30e. Can be adopted.
また、図６（ｃ）に示すように、側板３５が、補強板３４から、断熱板３２の積層側とは反対側に延びていてもよい。また、図６（ｄ）に示すように、補強板３４（金属箱体３１）のねじれ剛性を高めるために、補強板３４の対角を結ぶようにリブ３９が設けられてもよい。尚、図６（ｄ）では、金属箱体３１内の、２本のリブ３９によって仕切られた４つの空間に、４つの断熱板３２がそれぞれ収容されている。 As shown in FIG. 6C, the side plate 35 may extend from the reinforcing plate 34 to the side opposite to the laminated side of the heat insulating plate 32. Further, as shown in FIG. 6D, ribs 39 may be provided so as to connect the diagonals of the reinforcing plate 34 in order to increase the torsional rigidity of the reinforcing plate 34 (metal box 31). In FIG. 6D, four heat insulating plates 32 are accommodated in the four spaces partitioned by the two ribs 39 in the metal box 31, respectively.
また、前記実施形態では、１枚の金属板にプレス加工を施すことによって、補強板３４と側板３５とが一体形成される例が開示されているが、１枚の金属板を折り曲げ、必要に応じて四隅に溶接を施すことで補強板３４と側板３５を形成してもよい。または、補強板３４に、この補強板３４とは別の板である、側板３５をボルトや溶接等で接合してもよい。 Moreover, in the said embodiment, although the example in which the reinforcement board 34 and the side board 35 are integrally formed is disclosed by giving a press work to one metal plate, one metal plate is bend | folded and required. Accordingly, the reinforcing plate 34 and the side plate 35 may be formed by welding at the four corners. Alternatively, the side plate 35, which is a plate different from the reinforcing plate 34, may be joined to the reinforcing plate 34 by bolts, welding, or the like.
また、図６（ｅ）に示すように、補強板３４の縁部に側板３５が設けられておらず、補強板３４に断熱板３２が積層されているだけでもよい。尚、この場合は、断熱板３２が補強板３４に対して位置ズレしないように、接着剤やボルト等によって断熱板３２を補強板３４に固定しておくことが好ましい。 Further, as shown in FIG. 6E, the side plate 35 is not provided at the edge of the reinforcing plate 34, and the heat insulating plate 32 may be simply laminated on the reinforcing plate 34. In this case, it is preferable to fix the heat insulating plate 32 to the reinforcing plate 34 with an adhesive, a bolt, or the like so that the heat insulating plate 32 is not displaced from the reinforcing plate 34.
２］前記実施形態では、図３、図４に示すように、断熱板３２の補強板３４と反対側の面に断熱補強板３３が積層されていたが、この断熱補強板３３が省略されてもよい。 2] In the above embodiment, as shown in FIGS. 3 and 4, the heat insulating reinforcing plate 33 is laminated on the surface of the heat insulating plate 32 opposite to the reinforcing plate 34, but this heat insulating reinforcing plate 33 is omitted. Also good.
３］前記実施形態では、扉部３０ｆを除く５つの箱壁部３０ａ〜３０ｅについては、補強板３４の断熱板３２とは反対側の面が保温箱１６の内側を向き、一方、扉部３０ｆについては補強板３４が断熱板３２よりも外側に配置されている。これについて、各箱壁部３０の姿勢（向き）をどのようにするかについては特に限定されない。例えば、扉部３０ｆも含めた全ての箱壁部３０において、補強板３４が内側を向くようにしてもよい。 3] In the above embodiment, for the five box wall portions 30a to 30e excluding the door portion 30f, the surface opposite to the heat insulating plate 32 of the reinforcing plate 34 faces the inside of the heat insulating box 16, while the door portion 30f. The reinforcing plate 34 is disposed outside the heat insulating plate 32. In this regard, how the posture (direction) of each box wall 30 is made is not particularly limited. For example, the reinforcing plate 34 may face the inside in all the box wall portions 30 including the door portion 30f.
あるいは、扉部３０ｆ以外の箱壁部３０においても、補強板３４が断熱板３２よりも外側に配置されてもよい。特に、ある箱壁部３０において、何らかの構造体が取り付けられる場合は、この箱壁部３０については、断熱板３２の外側に付帯部品の取り付け強度を保つため、また、選定によっては、柔らかい発泡樹脂製の断熱板３２が外側に露出しないように、補強板３４が断熱板３２よりも外側に位置していることが好ましい。
Alternatively, the reinforcing plate 34 may be disposed outside the heat insulating plate 32 also in the box wall portion 30 other than the door portion 30f. In particular, in some Hakokabe unit 30, if any structure is attached, this Hakokabe unit 30 for maintaining the mounting strength of the accessory components on the outside of the sectional heat plate 32 and by the selection, soft foam It is preferable that the reinforcing plate 34 is located outside the heat insulating plate 32 so that the resin heat insulating plate 32 is not exposed to the outside.
４］保温箱１６内に収容される、加熱ローラの構成については特に限定されるものではない。例えば、前記特許文献１に開示されているような加熱ローラの構成であってもよい。即ち、図７に示すように、保温箱４６内には、内部ヒータ４２を有する加熱ローラであるゴデットローラ４３と、非加熱ローラであるセパレートローラ４４が収容されている。保温箱４６の糸導入口４６ａから導入された複数の糸Ｙは、ゴデットローラ４３とセパレートローラ４４の間に複数回巻き付けられる。ゴデットローラ４３との接触によって加熱された複数の糸Ｙは、保温箱４６の糸導出口４６ｂから下流側へ送られる。 4] The configuration of the heating roller housed in the heat insulating box 16 is not particularly limited. For example, a configuration of a heating roller as disclosed in Patent Document 1 may be used. That is, as shown in FIG. 7, a godet roller 43 that is a heating roller having an internal heater 42 and a separation roller 44 that is a non-heating roller are accommodated in the heat insulation box 46. The plurality of yarns Y introduced from the yarn introduction port 46 a of the heat insulation box 46 are wound around the godet roller 43 and the separation roller 44 a plurality of times. The plurality of yarns Y heated by the contact with the godet roller 43 are sent to the downstream side from the yarn outlet 46 b of the heat retaining box 46.
５］前記実施形態では、保温箱１６を構成する６つの箱壁部３０の全てが、金属製の補強板３４と側板３５からなる金属箱体３１と、発泡樹脂からなる断熱板３２とを有する構造であった。これに対して、６つの箱壁部３０のうちの一部が、上記とは異なる構造を有するものであってもよい。例えば、６つの箱壁部３０のうち、扉部３０ｆを除く５つの箱壁部３０ａ〜３０ｆは、補強板３４と断熱板３２の積層構造とし、一方、保温機能以外の異なる機能（例えば、オペレータの操作性）も要求される扉部３０ｆについては、軽量化等を重視して異なる構造を採用してもよい。 5] In the embodiment, all of the six box wall portions 30 constituting the heat insulation box 16 have the metal box body 31 made of the metal reinforcing plate 34 and the side plate 35 and the heat insulating plate 32 made of the foamed resin. It was a structure. On the other hand, some of the six box wall portions 30 may have a structure different from the above. For example, among the six box wall portions 30, the five box wall portions 30a to 30f excluding the door portion 30f have a laminated structure of the reinforcing plate 34 and the heat insulating plate 32, while different functions other than the heat retaining function (for example, an operator For the door portion 30f that also requires high operability, a different structure may be adopted with an emphasis on weight reduction.
