Description
本發明有關絲線加熱輥的保溫箱及其製造方法。 The invention relates to an incubator for a wire heating roller and a method of manufacturing the same.
專利文獻1中公開了將從紡絲裝置紡出的多根絲線加熱並拉伸的裝置。該裝置具有用來拉伸絲線的2個輥單元。各輥單元具有加熱輥(導絲輥)和分離輥。在各輥單元中，絲線在加熱輥與分離輥之間被多次纏繞，通過在此期間與加熱輥的接觸，絲線被加熱到規定溫度。並且，位於絲線行走方向下游側的輥單元的加熱輥的旋轉速度(喂絲速度)比位於上游側的輥單元的加熱輥快。由此，被上游側的輥單元預熱過的絲線通過2個輥單元之間的速度差而被拉伸。 Patent Document 1 discloses an apparatus for heating and stretching a plurality of yarns spun from a spinning device. The device has two roller units for drawing the wires. Each roller unit has a heating roller (guide roller) and a separation roller. In each of the roller units, the wire is wound a plurality of times between the heating roller and the separation roller, and the wire is heated to a predetermined temperature by contact with the heating roller during this period. Further, the rotation speed (feeding speed) of the heating roller of the roller unit located on the downstream side in the wire running direction is faster than the heating roller of the roller unit located on the upstream side. Thereby, the yarn preheated by the upstream roller unit is stretched by the speed difference between the two roller units.
但是，在上述專利文獻1中，包含加熱輥的輥單元被收容在保溫箱中。雖然對保溫箱的具體構成在專利文獻1中沒有特別記載，但例如可得知以下構成的保溫箱。圖8為以往的保溫箱的立體圖。圖8所示的保溫箱100具有分別由不銹鋼等金屬板形成的箱體101和框體101c。並且，在箱體101的內壁 101a與外壁101b之間填充有石棉等非定形的隔熱材103。 However, in Patent Document 1 described above, the roller unit including the heating roller is housed in the incubator. Although the specific structure of the heat retention box is not specifically described in Patent Document 1, for example, an incubator having the following configuration can be known. Fig. 8 is a perspective view of a conventional incubator. The incubator 100 shown in Fig. 8 has a casing 101 and a casing 101c each formed of a metal plate such as stainless steel. And, on the inner wall of the case 101 An amorphous heat insulating material 103 such as asbestos is filled between the 101a and the outer wall 101b.
上述保溫箱100如以下製作。首先，通過焊接將多塊金屬板互相接合，組裝箱體101的內壁101a和外壁101b。並且，在內壁101a與外壁101b之間設置有多個加強肋。接著，在箱體101的內壁101a與外壁101b之間填充石棉等隔熱材103。然後，通過焊接將框體101c安裝到箱體101上，封閉內壁101a與外壁101b之間的填充了隔熱材103的間隙。另外，雖然圖8省略了圖示，但在該保溫箱100上開閉自由地安裝有遮蓋前面的門。該門也與箱體101一樣，全周用金屬板圍繞，成為在其內部填充了石棉等的非定形隔熱材的保溫構造。 The above incubator 100 is produced as follows. First, a plurality of metal plates are joined to each other by welding, and the inner wall 101a and the outer wall 101b of the casing 101 are assembled. Further, 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 asbestos is filled between the inner wall 101a of the casing 101 and the outer wall 101b. Then, the frame body 101c is attached to the casing 101 by welding, and a gap filled between the inner wall 101a and the outer wall 101b filled with the heat insulating material 103 is closed. In addition, although the illustration is abbreviate|omitted in FIG. 8, the door which covers a front surface is opened and closed in this insulated box 100. The door is also surrounded by a metal plate as in the case of the casing 101, and is a heat insulating structure in which an amorphous heat insulating material such as asbestos is filled inside.
〔專利文獻1〕日本特開2012-214913號公報。 [Patent Document 1] Japanese Laid-Open Patent Publication No. 2012-214913.
圖8所示的以往的保溫箱存在以下問題。首先，通過焊接將多塊大的金屬板接合來組裝外壁和內壁的作業非常費功夫。並且，由於石棉的隔熱性能不是很高，因此作為保溫箱的隔熱性能低，向外部的散熱量，即熱能損失大。並且，在對箱體101的內壁101a與外壁101b之間填充石棉等非定形的隔熱材103時，在內壁101a的裡側和外壁101b內的角隅部等手難以到達的部分，填充隔熱材103困難。因此，根據作業者熟練程度的不同，存在隔熱材103的填充密度變得不均勻的擔憂。 The conventional incubator shown in Fig. 8 has the following problems. First, the work of assembling the outer wall and the inner wall by joining a plurality of large metal plates by welding is very laborious. Further, since the heat insulating performance of the asbestos is not very high, the heat insulating performance as the heat insulating box is low, and the heat radiation amount to the outside, that is, the heat energy loss is large. When a non-shaped heat insulating material 103 such as asbestos is filled between the inner wall 101a of the casing 101 and the outer wall 101b, the inner side of the inner wall 101a and the corner portion of the outer wall 101b are difficult to reach by hand. It is difficult to fill the heat insulating material 103. Therefore, depending on the skill level of the operator, there is a concern that the packing density of the heat insulating material 103 becomes uneven.
另外，以往廣泛使用的石棉等隔熱材不定形、完全沒有剛性，因此有用構成內壁101a和外壁101b的金屬板來確保保溫箱剛性的必要。但是，如果為了提高剛性而增加 金屬板的厚度時，則保溫箱變重，保養等的作業性降低。並且，在取代增加金屬板的厚度而在內壁101a與外壁101b之間設置加強肋來提高保溫箱的剛性的情況下，由於內部的熱量通過加強肋從內壁101a向外壁101b傳導，因此保溫性能下降。 Further, since the heat insulating material such as asbestos which has been widely used in the past is indefinite and has no rigidity at all, it is necessary to secure the rigidity of the heat insulating box by using the metal plate constituting the inner wall 101a and the outer wall 101b. However, if it increases in order to increase rigidity When the thickness of the metal plate is increased, the heat insulating box becomes heavy, and workability such as maintenance is lowered. Further, in the case where the reinforcing rib is provided between the inner wall 101a and the outer wall 101b instead of increasing the thickness of the metal plate to increase the rigidity of the heat insulating box, since the internal heat is conducted from the inner wall 101a to the outer wall 101b through the reinforcing rib, the heat is maintained. Performance is declining.
本發明的目的是提供一種組裝容易的保溫箱。並且，本發明的另一個目的是提供一種隔熱性能高，並且隔熱性能均勻的保溫箱。 It is an object of the present invention to provide an incubator that is easy to assemble. Further, another object of the present invention is to provide an incubator having high heat insulating properties and uniform heat insulating properties.
第1發明的絲線加熱輥的保溫箱為收容加熱絲線的絲線加熱輥的保溫箱，其特徵為：構成保溫箱的多個箱壁部分別具有隔熱板和被層疊在該隔熱板上的金屬製的加強板。 The heat insulating box of the wire heating roller according to the first aspect of the present invention is an insulated box for a wire heating roller for accommodating a heating wire, wherein the plurality of tank wall portions constituting the heat insulating box respectively have a heat insulating panel and are laminated on the heat insulating panel. Metal reinforcing plate.
根據本發明，保溫箱的箱壁部具有隔熱板層疊在金屬製的加強板上的構造。因此，通過將隔熱板層疊到加強板上能夠簡單地形成各箱壁部。雖然既可以使隔熱板層疊到加強板上先分別形成多個箱壁部然後再接合，也可以預先接合多塊加強板然後使隔熱板層疊到各加強板上，但無論如何，保溫箱的組裝都是非常容易。並且，例如由發泡樹脂等構成的隔熱板的隔熱性能一般比石棉等高數倍。因此，各箱壁部的隔熱性能變高，進而使保溫箱整體的隔熱性能也提高。而且，隔熱板的安裝作業只要將規定尺寸的隔熱板層疊到加強板上即可完成，因此即使在不熟練的操 作人員進行作業的情況下，保溫箱的隔熱性能也難以變得不均勻。 According to the invention, the tank wall portion of the incubator has a structure in which the heat insulating panels are laminated on a metal reinforcing plate. Therefore, each of the tank wall portions can be easily formed by laminating the heat insulating sheets to the reinforcing sheets. Although it is possible to laminate the heat insulating panels to the reinforcing panels to form a plurality of tank wall portions and then join them, it is also possible to pre-join the plurality of reinforcing panels and then laminate the heat insulating panels to the reinforcing panels, but in any case, the incubator The assembly is very easy. Further, for example, the heat insulating performance of a heat insulating sheet made of a foamed resin or the like is generally several times higher than that of asbestos or the like. Therefore, the heat insulating performance of each of the tank wall portions is increased, and the heat insulating performance of the entire heat insulating box is also improved. Moreover, the installation work of the heat shield can be completed by laminating the heat shield of a predetermined size onto the reinforcing plate, so even in an unskilled operation When the person performs the work, it is difficult to make the heat insulating performance of the incubator uneven.
第2發明的絲線加熱輥的保溫箱，其特徵為：上述第1發明中，在各箱壁部中，上述金屬製的加強板僅被層疊在上述隔熱板的朝保溫箱內側的裡面或朝保溫箱外側的外面中的任一個面上。 According to a second aspect of the invention, in the first aspect of the invention, in the box wall portion, the metal reinforcing plate is laminated only on an inner side of the heat insulating box facing the inside of the heat insulating box or To either side of the outside of the outside of the incubator.
上述圖8所示的以往的保溫箱中，箱體101的內壁101a和與大氣接觸的外壁101b用框體101c和未圖示的加強肋等熱傳導率高的金屬材料連接。對於保溫箱的門也一樣。由於以上的構成，內部的熱量通過熱傳導而傳遞到外壁101b，熱能散發到大氣中。並且，仍存在有外壁101b的溫度變高的問題。 In the conventional incubator shown in Fig. 8, the inner wall 101a of the casing 101 and the outer wall 101b which is in contact with the atmosphere are connected by a metal material having a high thermal conductivity such as a casing 101c and a reinforcing rib (not shown). The same is true for the door of the incubator. Due to the above configuration, the internal heat is transferred to the outer wall 101b by heat conduction, and the heat energy is radiated to the atmosphere. Further, there is still a problem that the temperature of the outer wall 101b becomes high.
這一點，在本發明中由於熱傳導率高的金屬加強板僅層疊在隔熱板的裡面或外面中的任一面上，因此能夠抑制內部的熱量在加強板中傳導而散發到外部的熱量。即，只在隔熱板的外面有加強板的情況下，保溫箱內部的高溫空氣不直接與金屬加強板接觸，熱量僅通過隔熱板傳遞到外面的加強板，因此外面的加強板不會變成高溫，可抑制從外面被散發的熱能的量。並且，在只有隔熱板的裡面有加強板的情況下，雖然裡面的加強板因保溫箱內部的高溫空氣而變成高溫，但熱傳導被隔熱板抑制。因此，傳遞到保溫箱外面的熱能被抑制，從外面散發的熱能的量也受到抑制。 In this case, in the present invention, since the metal reinforcing plate having a high thermal conductivity is laminated only on either of the inside and the outside of the heat insulating plate, it is possible to suppress heat that is radiated inside the reinforcing plate and radiated to the outside. That is, in the case where there is a reinforcing plate on the outside of the heat insulating plate, the high temperature air inside the heat insulating box is not directly in contact with the metal reinforcing plate, and the heat is transmitted only to the outer reinforcing plate through the heat insulating plate, so the outer reinforcing plate does not It becomes high temperature, and the amount of heat energy radiated from the outside can be suppressed. Further, in the case where only the reinforcing plate is provided on the inside of the heat insulating plate, although the reinforcing plate inside becomes high temperature due to the high temperature air inside the heat insulating box, heat conduction is suppressed by the heat insulating plate. Therefore, the heat energy transmitted to the outside of the incubator is suppressed, and the amount of heat energy radiated from the outside is also suppressed.
在上述第1或第2發明中，上述隔熱板以發泡樹脂構 成為佳(第3發明)。這種情況下，保溫箱的隔熱性能變高。 In the above first or second invention, the heat insulating plate is made of a foamed resin It is good (the third invention). In this case, the thermal insulation performance of the incubator becomes high.
第4發明的絲線加熱輥的保溫箱，其特徵為：上述第1~第3的任一發明中，在上述加強板的邊緣部設置有從該邊緣部沿著與上述加強板正交的方向延伸的金屬製的側板。 According to a fourth aspect of the invention, in the first aspect of the invention, the edge portion of the reinforcing plate is provided in a direction orthogonal to the reinforcing plate from the edge portion. Extended metal side panels.
通過在加強板的邊緣部設置金屬製的側板，箱壁部的彎曲剛性變高，保溫箱整體的剛性也提高。或者，能夠減薄加強板的厚度，使得保溫箱輕量化。 By providing a metal side plate at the edge portion of the reinforcing plate, the bending rigidity of the box wall portion is increased, and the rigidity of the entire heat insulating box is also improved. Alternatively, the thickness of the reinforcing plate can be reduced to make the incubator lightweight.
第5發明的絲線加熱輥的保溫箱，其特徵為：在上述第4發明中，上述加強板和上述側板為一體成形。 According to a fourth aspect of the invention, in the fourth aspect of the invention, the reinforcing plate and the side plate are integrally formed.
由於不需要通過焊接等接合加強板和側板的作業，因此箱壁部的形成變得簡單。 Since the work of joining the reinforcing plate and the side plates by welding or the like is not required, the formation of the wall portion of the tank becomes simple.
第6發明的絲線加熱輥的保溫箱，其特徵為：在上述第4或第5發明中，上述側板從上述加強板延伸到上述隔熱板的層疊側。 According to a fourth aspect of the invention, in the fourth aspect of the invention, the side plate extends from the reinforcing plate to a side of the heat insulating plate.
根據本發明，層疊在加強板上的隔熱板的側面被側板遮蓋，藉側板保護隔熱板的側面。 According to the present invention, the side surface of the heat insulating panel laminated on the reinforcing plate is covered by the side panel, and the side panel protects the side surface of the heat insulating panel.
第7發明的絲線加熱輥的保溫箱，其特徵為：上述第6發明中，在上述加強板的邊緣部的至少與上述加強板的面方向平行的方向上位於彼此相反側的2個部分上設置上述側板，上述隔熱板被收容在上述側板所夾著的空間內，而層疊在上述加強板上。 According to a sixth aspect of the invention, in the sixth aspect of the invention, the edge portion of the reinforcing plate is located on at least two portions opposite to each other in a direction parallel to a surface direction of the reinforcing plate. The side panel is provided, and the heat shield is housed in a space sandwiched by the side panel and laminated on the reinforcing panel.
由於在加強板的邊緣部的與面方向平行的方向上位於 相反側的2個部分上分別設置有側板，因此箱壁部的剛性進一步變高。並且，只要嵌入地將隔熱板收容到由側板夾著的空間即可，隔熱板的安裝簡單。並且，隔熱板相對於加強板的位置偏離被側板所限制。 Due to the direction parallel to the plane direction of the edge portion of the reinforcing plate The side plates are provided on the two opposite sides, respectively, so that the rigidity of the box wall portion is further increased. Further, as long as the heat insulating plate is housed in the space sandwiched by the side plates, the heat insulating plate can be easily mounted. Moreover, the positional deviation of the heat shield relative to the stiffener is limited by the side panels.
第8發明的絲線加熱輥的保溫箱，其特徵為：在上述第7發明中，上述側板連續設置遍及於上述加強板的上述邊緣部的全周，由上述加強板和上述側板形成金屬箱體，上述隔熱板被收容在上述金屬箱體內的空間內，而層疊在上述加強板上。 According to a seventh aspect of the invention, in the seventh aspect of the invention, the side plate is continuously provided over the entire circumference of the edge portion of the reinforcing plate, and the reinforcing plate and the side plate form a metal case. The heat shield is housed in a space in the metal case and laminated on the reinforcing plate.
由於遍及加強板的邊緣部的全周地連續設置側板，所以金屬箱體的剛性高，因此箱壁部的剛性也變得非常高。並且，由於隔熱板的側面全周被側板所遮蓋，因此隔熱板的側面被確實地保護。並且，隔熱板相對於加強板的位置偏離被側板確實地限制。 Since the side plates are continuously provided over the entire circumference of the edge portion of the reinforcing plate, the rigidity of the metal case is high, and therefore the rigidity of the box wall portion is also extremely high. Further, since the side surface of the heat shield is covered by the side panel, the side surface of the heat shield is reliably protected. Moreover, the positional deviation of the heat shield from the stiffener is reliably limited by the side panels.
第9發明的絲線加熱輥的保溫箱，其特徵為：上述第1~第8的任一發明中，在上述多個箱壁部中的至少一個中，其加強板的與上述隔熱板相反側的面朝向保溫箱的內側，構成上述保溫箱的裡面。 The invention according to any one of the first to eighth aspects of the present invention, wherein at least one of the plurality of tank wall portions has a reinforcing plate opposite to the heat insulating plate The side of the side faces the inside of the incubator and constitutes the inside of the incubator.
金屬製的加強板與隔熱板相比表面硬度高。因此，如果加強板的與隔熱板相反側的面構成保溫箱的裡面時，則即使由於斷絲而纏繞在加熱輥上的絲線敲打保溫箱的裡面，或者導紗時操作人員使吸槍碰撞保溫箱的裡面，裡面也不容易損壞。並且，由於金屬製的加強板的表面平滑，因此即使油劑和碎絲等塵埃或者污垢附著在保溫箱的裡 面，清掃也容易。 The metal reinforcing plate has a higher surface hardness than the heat insulating plate. Therefore, if the face of the reinforcing plate opposite to the heat insulating plate constitutes the inside of the heat insulating box, even if the wire wound on the heat roller is broken inside the incubator due to the broken wire, or the operator causes the sniffer to collide when guiding the yarn Inside the incubator, the inside is not easily damaged. Moreover, since the surface of the metal reinforcing plate is smooth, even dust or dirt such as oil and broken wire adheres to the incubator. It is easy to clean.
第10發明的絲線加熱輥的保溫箱，其特徵為：上述第1~第9中的任一發明中，在上述隔熱板的與上述加強板相反側的面上層疊有隔熱加強板。 According to a tenth aspect of the invention, in the first aspect of the invention, in the heat insulating material, the heat insulating reinforcing plate is laminated on a surface of the heat insulating plate opposite to the reinforcing plate.
該構成中隔熱板的與加強板相反側的面被隔熱加強板保護。並且，由於通過設置隔熱加強板，成為用剛性高的加強板和隔熱加強板夾著剛性比較低的隔熱板的所謂三明治構造，因此能夠提高整體的剛性。另外，隔熱加強板既可以用板狀的構件構成，也可以是塗敷液狀樹脂後硬化的具有剛性的層，其形態不加以特別限制。 In this configuration, the surface of the heat insulating plate opposite to the reinforcing plate is protected by the heat insulating reinforcing plate. In addition, since the heat insulating reinforcing plate is provided, the so-called sandwich structure in which the rigid plate having a relatively low rigidity is sandwiched between the reinforcing plate and the heat insulating reinforcing plate having high rigidity can improve the overall rigidity. Further, the heat insulating reinforcing plate may be formed of a plate-shaped member or a rigid layer which is cured by applying a liquid resin, and the form thereof is not particularly limited.
第11發明的絲線加熱輥的保溫箱的製造方法為收容加熱絲線的絲線加熱輥的保溫箱的製造方法，其特徵為，具備以下步驟：接合多塊加強板的組裝步驟，以及將隔熱板分別層疊到上述多塊加強板上，分別形成構成保溫箱的多個箱壁部的箱壁部形成步驟。 A method of manufacturing a heat insulating box for a wire heating roller according to a twelfth aspect of the present invention is a method for producing a heat insulating box for a wire heating roller for accommodating a heating wire, comprising the steps of: assembling an assembly of a plurality of reinforcing plates, and installing a heat insulating plate Each of the plurality of reinforcing plates is laminated on each of the plurality of reinforcing plates to form a tank wall forming step of the plurality of tank wall portions constituting the heat insulating box.
本發明接合多塊金屬製的加強板來組裝箱體。並且，通過在箱壁部的形成步驟中將隔熱板分別層疊到多塊加強板上形成多個箱壁部，能夠形成隔熱性能高的箱壁部。並且，只要將隔熱板層疊到加強板上即可完成作業。因此，即使在不熟練的操作人員進行作業的情況下，保溫箱的隔熱性能也難以變得不均勻。另外，組裝步驟和箱壁部形成步驟(層疊隔熱板)的順序不加以特別限制，可以先進行任何一個步驟。 The present invention joins a plurality of metal reinforcing plates to assemble a casing. Further, by forming the plurality of tank wall portions by laminating the heat insulating panels on the plurality of reinforcing plates in the step of forming the tank wall portion, it is possible to form the tank wall portion having high heat insulating performance. Also, the work can be completed by laminating the heat shield on the reinforcing plate. Therefore, even in the case where an unskilled operator performs work, it is difficult to make the heat insulating performance of the incubator uneven. Further, the order of the assembly step and the tank wall forming step (the laminated heat insulating panel) is not particularly limited, and any one of the steps may be performed first.
第12發明的絲線加熱輥的保溫箱的製造方法，其特 徵為：在上述第11發明中，還具備遍及上述加強板的邊緣部的全周連續地設置沿著與上述加強板正交的方向延伸的側板，形成由上述加強板和上述側板構成的金屬箱體的金屬箱體形成步驟，在上述組裝步驟中接合多個上述金屬箱體。 A method of manufacturing a heat insulating box for a wire heating roller according to a twelfth aspect of the invention According to the eleventh aspect of the invention, the side plate extending in a direction orthogonal to the reinforcing plate is continuously provided over the entire circumference of the edge portion of the reinforcing plate, and the metal formed of the reinforcing plate and the side plate is formed. A metal case forming step of the case, wherein the plurality of metal cases are joined in the assembling step.
由於遍及加強板邊緣部的全周連續地設置側板，所以金屬箱體的剛性高，因此箱壁部的剛性也變得非常高。 Since the side plates are continuously provided over the entire circumference of the edge portion of the reinforcing plate, the rigidity of the metal case is high, and therefore the rigidity of the box wall portion is also extremely high.
第13發明的絲線加熱輥的保溫箱的製造方法，其特徵為：上述第12發明中，在上述箱壁部形成步驟中，將上述隔熱板收容到上述金屬箱體內的空間內而層疊在上述加強板上。 According to a twelfth aspect of the invention, in the casing wall forming step, the heat insulating panel is housed in a space in the metal casing and laminated on the heat insulating box. The above reinforcement plate.
由於只要嵌入地將隔熱板收容到由加強板和側板形成的金屬箱體內即可完成隔熱板的安裝，因此作業變得非常簡單。並且，由於遍及加強板邊緣部的全周地連續設置側板，因此隔熱板相對於加強板的位置偏離被該側板確實地限制。而且，由於隔熱板的側面全周被側板所遮蓋，因此隔熱板的側面被確實地保護。 Since the heat insulating plate can be installed by simply accommodating the heat insulating plate into the metal case formed by the reinforcing plate and the side plate, the operation becomes very simple. Further, since the side plates are continuously provided over the entire circumference of the edge portion of the reinforcing plate, the positional deviation of the heat insulating plate with respect to the reinforcing plate is surely restricted by the side plates. Moreover, since the side surface of the heat shield is covered by the side panel, the side surface of the heat shield is reliably protected.

The spinning stretcher 3 is provided with an oil guide 10 and five godet rollers 11 to 15 (wire heating roller in the present invention). The oil agent guide 10 is a member that respectively applies an oil agent to the plurality of yarns Y spun from the spinning device 2.
5個導絲輥11~15由未圖示的電動機分別旋轉驅動。並且，5個導絲輥11~15分別為在內部具有加熱器的加熱輥，收容在長方體形狀的保溫箱16內。在保溫箱16的右側壁部，形成有用來將多根絲線Y導入保溫箱16內的絲線導入口16a和用來將多根絲線Y從保溫箱16內向外部匯出的絲線匯出口16b。另外，有關保溫箱16的詳細構成在後面說明。 The five godet rollers 11 to 15 are rotationally driven by motors (not shown). Further, each of the five godet rollers 11 to 15 is a heating roller having a heater therein, and is housed in a rectangular parallelepiped incubator 16. In the right side wall portion of the heat insulating box 16, a wire introduction port 16a for guiding the plurality of wires Y into the heat insulating box 16 and a wire outlet 16b for discharging the plurality of wires Y from the inside of the heat insulating box 16 to the outside are formed. Further, the detailed configuration of the incubator 16 will be described later.
在油劑引導器10內被賦予了油劑的多根絲線Y經由引導輥17從絲線導入口16a向保溫箱16內引導。被導入 保溫箱16內的多根絲線Y從下側的導絲輥11依序卷掛到5個導絲輥11~15上。 The plurality of yarns Y to which the oil agent is applied in the oil guide 10 are guided from the wire introduction port 16a into the heat retention box 16 via the guide rolls 17. Being imported The plurality of yarns Y in the heat insulating box 16 are sequentially wound from the lower godet roller 11 to the five godet rollers 11 to 15.
下側的3個導絲輥11~13為在拉伸多根絲線Y之前用來預熱的加熱輥，該等的加熱溫度(輥表面溫度)被設定在絲線Y的玻璃轉移點以上的溫度(例如80℃)。另一方面，上側的2個導絲輥14、15為用來熱定型被拉伸後的多根絲線Y的加熱輥，該等的加熱溫度被設定在比下側3個導絲輥11~13的加熱溫度高的溫度(例如120℃)。並且，上側2個導絲輥14、15的絲線Y的輸送速度比下側3個導絲輥11~13的快。 The three godet rollers 11 to 13 on the lower side are heating rollers for preheating before stretching the plurality of yarns Y, and the heating temperatures (roller surface temperatures) are set at temperatures above the glass transition point of the yarn Y. (eg 80 ° C). On the other hand, the upper two godet rollers 14, 15 are heating rollers for heat-setting the plurality of drawn yarns Y, and the heating temperatures are set to be lower than the lower three godet rollers 11~ The temperature at which the heating temperature of 13 is high (for example, 120 ° C). Further, the conveying speed of the yarn Y of the upper two godet rollers 14 and 15 is faster than that of the lower three godet rollers 11 to 13.
被導入保溫箱16內的多根絲線Y，首先在被下側3個導絲輥11~13輸送期間被預熱到能夠拉伸的溫度。接著，預熱後的多根絲線Y被2個導絲輥13、14之間的喂絲速度差所拉伸。而且，多根絲線Y在上側2個導絲輥14、15輸送期間被加熱到更高溫度，將拉伸後的狀態熱定型。如上述拉伸後的多根絲線Y被從絲線匯出口16b匯出到保溫箱16外，進而藉引導輥18輸送到絲線捲繞裝置4。 The plurality of yarns Y introduced into the heat insulating box 16 are first preheated to a temperature at which stretching is possible while being conveyed by the lower three godet rollers 11 to 13. Next, the pre-heated plurality of yarns Y are stretched by the difference in the feeding speed between the two godet rollers 13, 14. Further, the plurality of yarns Y are heated to a higher temperature during the conveyance of the upper two godet rollers 14, 15, and the shape after stretching is heat-set. The plurality of yarns Y which have been stretched as described above are taken out from the wire outlet 16b to the outside of the heat insulating box 16, and are conveyed to the wire winding device 4 by the guide roller 18.
絲線捲繞裝置4配置在紡絲拉伸裝置3的下方。該絲線捲繞裝置4具備筒管支架20和接觸輥21等。筒管支架20具有沿圖1的紙面垂直方向延伸的細長形狀，由未圖示的電動機旋轉驅動。在該筒管支架20上沿其軸線方向排列安裝有多個筒管22。絲線捲繞裝置4通過使筒管支架20旋轉而將多根絲線Y同時捲繞到多個筒管22上，形 成多個捲繞卷裝23。接觸輥21與多個捲繞卷裝23的表面接觸來賦予規定的接觸壓力，梳理捲繞卷裝23的形狀。 The wire winding device 4 is disposed below the spinning and stretching device 3. This wire winding device 4 includes a bobbin holder 20, a contact roller 21, and the like. The bobbin holder 20 has an elongated shape extending in the vertical direction of the paper surface of Fig. 1, and is rotationally driven by a motor (not shown). A plurality of bobbins 22 are arranged in the axial direction of the bobbin holder 20. The wire winding device 4 simultaneously winds a plurality of wires Y onto the plurality of bobbins 22 by rotating the bobbin holder 20, A plurality of winding packages 23 are formed. The contact roller 21 comes into contact with the surface of the plurality of winding packages 23 to impart a predetermined contact pressure, and combs the shape of the wound package 23.
接著，詳細說明收容5個導絲輥11~15的保溫箱16。圖2為保溫箱的立體圖。圖3為保溫箱的一個箱壁部的分解立體圖。圖4為關閉門部後的狀態下保溫箱的縱剖視圖。另外，如圖2所示定義保溫箱16的前後、左右及上下的各方向，以下適當使用該等方向用語進行說明。 Next, the incubator 16 that accommodates the five godet rolls 11 to 15 will be described in detail. Figure 2 is a perspective view of the incubator. Figure 3 is an exploded perspective view of a tank wall portion of the incubator. Fig. 4 is a longitudinal sectional view of the incubator in a state in which the door portion is closed. Further, as shown in FIG. 2, the directions of the front, back, left and right, and up and down of the heat insulating box 16 are defined, and the following terms are appropriately used for explanation.
如圖2~圖4所示，保溫箱16通過連結6個箱壁部30而形成為長方體形狀。6個箱壁部30為上壁部30a、下壁部30b、左側壁部30c、右側壁部30d、後壁部30e、以及用鉸鏈等自由轉動地安裝到左側壁部30c前端部的門部30f。在右側壁部30d的下端部及上端部分別形成有成為絲線導入口16a和絲線匯出口16b的2個缺口。 As shown in FIGS. 2 to 4, the heat insulating box 16 is formed in a rectangular parallelepiped shape by connecting the six tank wall portions 30. The six tank wall portions 30 are an upper wall portion 30a, a lower wall portion 30b, a left side wall portion 30c, a right side wall portion 30d, a rear wall portion 30e, and a door portion that is rotatably attached to the front end portion of the left side wall portion 30c by a hinge or the like. 30f. Two notches which are the wire introduction port 16a and the wire outlet 16b are formed in the lower end portion and the upper end portion of the right side wall portion 30d.
如圖3所示，6個箱壁部30分別為具有金屬箱體31、隔熱板32、隔熱加強板33的面板。金屬箱體31為用不銹鋼等金屬板形成的內部能夠收容隔熱板32的矩形箱形狀的構造體。金屬箱體31具有通過衝壓加工而一體成形的加強板34和側板35。更詳細是在成為金屬箱體31底部的矩形形狀的加強板34的邊緣部設置有沿與其面方向正交的方向，並且朝層疊隔熱板32的一側(圖3的上側)延伸的側板35。該側板35遍及加強板34邊緣部的全周連續地形成。 As shown in FIG. 3, each of the six tank wall portions 30 is a panel having a metal case 31, a heat insulating plate 32, and a heat insulating reinforcing plate 33. The metal case 31 is a rectangular box-shaped structure in which a heat insulating plate 32 can be accommodated inside a metal plate such as stainless steel. The metal case 31 has a reinforcing plate 34 and a side plate 35 which are integrally formed by press working. More specifically, the edge portion of the rectangular reinforcing plate 34 which is the bottom of the metal case 31 is provided with a side plate extending in a direction orthogonal to the surface direction thereof and extending toward one side (upper side of FIG. 3) of the laminated heat insulating panel 32. 35. The side plate 35 is continuously formed over the entire circumference of the edge portion of the reinforcing plate 34.
隔熱板32用熱傳導率比金屬低的材料形成。本實施 形態中具體是發泡樹脂(合成樹脂發泡體)形成。由於被收容在保溫箱16內的導絲輥11~15的加熱溫度，例如被設定在80~120℃的溫度，因此構成保溫箱16的隔熱板32要求該設定溫度以上的耐熱性。在耐熱性不足的情況下，也可以在加強板34和側板35的與隔熱板32接觸的面上塗敷隔熱塗料。並且，為了抑制從保溫箱16向外部的散熱，當然盡可能以提高隔熱板32的隔熱性為佳。 The heat shield 32 is formed of a material having a lower thermal conductivity than metal. This implementation Specifically, the foamed resin (synthetic resin foam) is formed in the form. Since the heating temperature of the godet rollers 11 to 15 accommodated in the heat insulating box 16 is set to, for example, a temperature of 80 to 120 ° C, the heat insulating plate 32 constituting the heat insulating box 16 is required to have heat resistance higher than the set temperature. In the case where the heat resistance is insufficient, the heat insulating coating may be applied to the surface of the reinforcing plate 34 and the side plate 35 that is in contact with the heat insulating plate 32. Further, in order to suppress heat radiation from the heat insulating box 16 to the outside, it is of course preferable to increase the heat insulating property of the heat insulating plate 32 as much as possible.
作為能夠適用於以上的隔熱板32的發泡樹脂，從耐熱性方面是以熱硬化性樹脂發泡材料為佳，例如可舉例如發泡酚醛樹脂(酚醛泡沫)。相對於以往的保溫箱使用的石棉的熱傳導率為0.05W/(m．K)，上述發泡酚醛樹脂(JIS A 9511酚醛泡沫)的熱傳導率為0.022W/(m．K)。並且，從成本方面考量，也可以取代上述酚醛泡沫而使用隔熱性能較差的材料。除此以外，作為能夠使用的材料，則舉例如纖維系隔熱材料的密度為16kg/m3以上的玻璃棉板(熱傳導率為0.045W/(m．K))、碳化軟木板(熱傳導率為0.041W/(m．K))，作為樹脂隔熱材料的環氧樹脂(熱傳導率為0.19W/(m．K))、貝克萊特酚醛樹脂(熱傳導率為0.21W/(m．K))、真空隔熱材料(熱傳導率為0.0052W/(m．K))等。隔熱板32被預先切斷成與金屬箱體31的加強板34大致相同的大小，然後被嵌入地收納到金屬箱體31內，層疊在加強板34上。並且，用設置在加強板34邊緣部的全周上的側板35限制隔熱板32相對於加強板34的位置偏離。另外，為了確實防 止位置偏離，隔熱板32也可以在被收容到金屬箱體31的狀態下用黏接劑等固定在金屬箱體31。 The foamed resin which can be applied to the above-mentioned heat insulating sheet 32 is preferably a thermosetting resin foamed material from the viewpoint of heat resistance, and examples thereof include a foamed phenol resin (phenolic foam). The thermal conductivity of the asbestos used in the conventional incubator was 0.05 W/(m.K), and the thermal conductivity of the above-mentioned expanded phenolic resin (JIS A 9511 phenolic foam) was 0.022 W/(m.K). Further, in consideration of cost, a material having poor heat insulating properties may be used instead of the above phenolic foam. In addition, as a material which can be used, for example, a glass wool board having a density of a fiber-based heat insulating material of 16 kg/m 3 or more (thermal conductivity: 0.045 W/(m.K)), carbonized cork board (thermal conductivity) 0.041 W/(m.K)), epoxy resin as a resin heat insulating material (thermal conductivity: 0.19 W/(m.K)), Becklet phenolic resin (thermal conductivity: 0.21 W/(m.K)) ), vacuum insulation material (thermal conductivity: 0.0052 W / (m. K)) and the like. The heat insulating plate 32 is cut into a size substantially the same as that of the reinforcing plate 34 of the metal case 31, and is then housed in the metal case 31 and laminated on the reinforcing plate 34. Further, the positional deviation of the heat insulating plate 32 with respect to the reinforcing plate 34 is restricted by the side plates 35 provided on the entire circumference of the edge portion of the reinforcing plate 34. Further, in order to surely prevent the positional deviation, the heat insulating plate 32 may be fixed to the metal case 31 with an adhesive or the like in a state of being housed in the metal case 31.
隔熱加強板33遮蓋隔熱板32的整個表面地層疊在隔熱板32的表面(與加強板34相反側的面)上。從保護隔熱板32的目的出發，隔熱加強板33用與隔熱板32相比隔熱性稍差、剛性和強度高的材料形成。另一方面，從保溫性的目的出發，能夠用隔熱性比金屬箱體31的加強板34優異的材料形成，例如，能夠使用酚醛樹脂等熱硬化性樹脂。如圖3所示，也可以通過在隔熱板32與隔熱加強板33之間再塗敷矽等液狀塗料形成被覆層36。被覆層36的塗料通過滲透到金屬箱體31、隔熱板32以及隔熱加強板33之間存在的間隙中來堵塞該等之間的間隙，防止來自外部的油劑、異物的侵入，能夠防止隔熱板32變質。 The heat insulating reinforcing plate 33 covers the entire surface of the heat insulating plate 32 on the surface of the heat insulating plate 32 (the surface opposite to the reinforcing plate 34). For the purpose of protecting the heat insulating panel 32, the heat insulating reinforcing plate 33 is formed of a material which is slightly inferior in heat insulating property and has high rigidity and strength as compared with the heat insulating panel 32. On the other hand, it is possible to form a material having a heat insulating property superior to that of the reinforcing plate 34 of the metal case 31, and for example, a thermosetting resin such as a phenol resin can be used. As shown in FIG. 3, the coating layer 36 may be formed by applying a liquid paint such as a crucible between the heat shield 32 and the heat insulating reinforcing plate 33. The coating material of the coating layer 36 penetrates the gap existing between the metal case 31, the heat insulating plate 32, and the heat insulating reinforcing plate 33 to block the gap therebetween, thereby preventing the intrusion of oil or foreign matter from the outside. The heat shield 32 is prevented from deteriorating.
如圖2、圖4所示，除門部30f以外的5個箱壁部30a~30e使金屬箱體31的加強板34的與隔熱板32相反側的面朝保溫箱16內側地連結。藉此，5個箱壁部30a~30e中，加強板34的與隔熱板32相反側的面分別構成保溫箱16的裡面，使隔熱板32位在比加強板34的更外側。利用該構成，5個箱壁部30a~30e外面的溫度不會變得太高。 As shown in FIGS. 2 and 4, the five tank wall portions 30a to 30e other than the door portion 30f connect the surface of the reinforcing plate 34 of the metal casing 31 opposite to the heat insulating panel 32 to the inside of the heat insulating box 16. Thereby, among the five tank wall portions 30a to 30e, the surfaces of the reinforcing plate 34 on the opposite side to the heat insulating panel 32 constitute the inside of the heat insulating box 16, and the heat insulating panel 32 is positioned outside the reinforcing plate 34. With this configuration, the temperatures outside the five tank wall portions 30a to 30e do not become too high.
另一方面，對於門部30f，金屬箱體31的加強板34也位在比隔熱板32更外側，加強板34的與隔熱板32相反側的面不朝向保溫箱16的內側。只有門部30f成為上 述配置的理由如下：雖然在門部30f的外面安裝有把手37等構成物，但為了能夠支承該構成物，以確保門部30f的外面側有足夠的剛性。即，能夠像圖4所示，將把手37配置在比隔熱板32更外側而能夠用螺栓等簡單地安裝在剛性高的加強板34上。 On the other hand, in the door portion 30f, the reinforcing plate 34 of the metal case 31 is also positioned outside the heat insulating plate 32, and the surface of the reinforcing plate 34 opposite to the heat insulating plate 32 does not face the inside of the heat insulating box 16. Only the door 30f becomes the upper The reason for the arrangement is as follows. Although the structure such as the handle 37 is attached to the outer surface of the door portion 30f, it is necessary to support the structure to ensure sufficient rigidity on the outer surface side of the door portion 30f. In other words, as shown in FIG. 4, the handle 37 can be disposed outside the heat insulating plate 32, and can be easily attached to the reinforcing plate 34 having high rigidity by bolts or the like.
另外，把手37也可以安裝到門部30f的側面。此情況下，在圖4中也可以是金屬箱體31的加強板34朝著保溫箱16內側的構成。但是，尤其是如下述的構成，無論是將把手37安裝到門部30f的前面的情況還是安裝到側面的情況，金屬箱體31的加強板34都有朝向保溫箱16外側的必要。圖5為具有其他形狀的門部的保溫箱的縱剖視圖。圖5的構成是為達到提高導紗作業性的目的，導絲輥11~15(圖5中只圖示3個輥11、13、15)的頂端部從上壁部30a、下壁部30b、左側壁部30c和右側壁部30d的前面突出。這種情況下，門部30f的內側有確保避免與導絲輥11~15的頂端部干涉的空間的必要。因此，門部30f具有U字形的剖面形狀。該門部30f為了將把手37安裝到其前面或側面，金屬箱體31的加強板34有位在比隔熱板32更外側的必要。 Further, the handle 37 may be attached to the side of the door portion 30f. In this case, in FIG. 4, the reinforcing plate 34 of the metal case 31 may be formed toward the inside of the heat insulating box 16. However, in particular, in the configuration described below, the reinforcing plate 34 of the metal case 31 is required to face the outside of the heat insulating box 16 regardless of the case where the handle 37 is attached to the front surface of the door portion 30f or the side surface. Fig. 5 is a longitudinal sectional view of an incubator having a door portion of another shape. In the configuration of Fig. 5, the tip end portions of the godet rollers 11 to 15 (only three rollers 11, 13, 15 are shown in Fig. 5) are from the upper wall portion 30a and the lower wall portion 30b for the purpose of improving the yarn guiding workability. The front faces of the left side wall portion 30c and the right side wall portion 30d protrude. In this case, it is necessary to ensure a space inside the door portion 30f to avoid interference with the tip end portions of the godet rollers 11 to 15. Therefore, the door portion 30f has a U-shaped cross-sectional shape. In order to attach the handle 37 to the front or side thereof, the door portion 30f is required to have the reinforcing plate 34 of the metal case 31 located outside the heat insulating plate 32.
並且，金屬製的加強板34因為有隔熱板32，不會到達受燙傷那麼高的溫度，但如果在門部30f上該加強板34露出在外側時，則操作者開閉操作門部30f之際，存在有手直接接觸溫度比常溫高的加強板34的擔憂。因此如圖4、圖5所示，門部30f中在金屬箱體31的外面也層疊有 隔熱層38。另外，該隔熱層38的材質等既可與層疊在隔熱板32上的隔熱加強板33相同，也可以不同。並且，在門部30f上，隔熱板32露出到保溫箱16的內側。其中，為防止碎絲或被切斷的行走絲引起的隔熱板32的破損，也可以在隔熱板32的保溫箱16內側的面上層疊未圖示的保護板。 Further, since the metal reinforcing plate 34 does not reach the temperature as high as the scald because of the heat insulating plate 32, if the reinforcing plate 34 is exposed outside on the door portion 30f, the operator opens and closes the operation door portion 30f. There is a concern that the hand directly contacts the reinforcing plate 34 whose temperature is higher than normal temperature. Therefore, as shown in FIGS. 4 and 5, the door portion 30f is also laminated on the outer surface of the metal case 31. Insulation layer 38. Further, the material or the like of 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, on the door portion 30f, the heat shield 32 is exposed to the inside of the heat insulating box 16. However, in order to prevent breakage of the heat shield 32 by the broken wire or the cut traveling wire, a protective plate (not shown) may be laminated on the inner surface of the heat insulating box 16 of the heat shield 32.
如圖4所示，保溫箱16在後壁部30e安裝於支承紡絲拉伸裝置3各構成部的機台40上。具體而言，在後壁部30e的加強板34與機台40之間，透過樹脂製的襯墊42藉穿插多個螺栓41而將保溫箱16固定在機台上。另外，為極力抑制從保溫箱16通過螺栓41向外部散熱，螺栓41以不是金屬製的零件，而是以樹脂製的零件為佳。 As shown in Fig. 4, the heat insulating box 16 is attached to the machine table 40 that supports the respective constituent portions of the spinning and stretching device 3 at the rear wall portion 30e. Specifically, between the reinforcing plate 34 of the rear wall portion 30e and the machine table 40, the heat insulating box 16 is fixed to the machine table by inserting a plurality of bolts 41 through the resin-made spacer 42. In addition, in order to suppress the heat dissipation from the heat insulating box 16 to the outside through the bolt 41 as much as possible, the bolt 41 is preferably made of a resin, not a metal part, but a resin part.
接著，說明上述保溫箱16的製造方法。保溫箱16的製造步驟大致劃分時，具備分別形成6個金屬箱體31的步驟(金屬箱體形成步驟)、接合6個金屬箱體31的步驟(組裝步驟)及向6個金屬箱體31層疊隔熱板32等形成箱壁部30的步驟(箱壁部形成步驟)。 Next, a method of manufacturing the above-described incubator 16 will be described. When the manufacturing steps of the heat insulating box 16 are roughly divided, the steps of forming the six metal cases 31 (the metal case forming step), the steps of joining the six metal cases 31 (the assembling step), and the six metal cases 31 are provided. The step of forming the tank wall portion 30 by the laminated heat insulating panel 32 or the like (the tank wall portion forming step).
另外，作為該等步驟的順序，雖可考慮以下2種，但任何一種方法都能夠實施。只要考慮作業性等適當選擇就可以。 Further, as the order of the steps, the following two types can be considered, but any of the methods can be carried out. Just consider the appropriate choices such as workability.
(1)金屬箱體形成步驟→組裝步驟(接合6個金屬箱體31)→箱壁部形成步驟(將隔熱板32等層疊到金屬箱體31上) (1) Metal case forming step → assembly step (joining six metal cases 31) → box wall forming step (stacking the heat insulating plate 32 and the like on the metal case 31)
(2)金屬箱體形成步驟→箱壁部形成步驟→組裝步 驟 (2) Metal case forming step → box wall forming step → assembly step Step
首先，對一塊金屬板實施衝壓加工，一體成形加強板34和側板35，製作金屬箱體31。用該要領分別形成6個金屬箱體31。 First, a metal plate is subjected to press working, and the reinforcing plate 34 and the side plate 35 are integrally formed to form a metal case 31. Six metal cases 31 are formed separately by this method.
組裝步驟中接合6個金屬箱體31。接合方法既可通過焊接將6個金屬箱體31互相接合，也可以利用螺栓等連結件接合。在此，如圖4所示，對於和6個箱壁部30中除門部30f以外的5個箱壁部30a~30e對應的金屬箱體31，該等的加強板34與隔熱板32相反側的面是以朝著保溫箱16內側的姿勢連接。另一方面，對於門部30f，在關閉的狀態以加強板34位在比隔熱板32外側的姿勢用鉸鏈等自由旋轉地接合到與左側壁部30c對應的金屬箱體31上。 Six metal cases 31 are joined in the assembly step. In the joining method, the six metal cases 31 may be joined to each other by welding, or may be joined by a joint such as a bolt. Here, as shown in FIG. 4, the reinforcing plate 34 and the heat insulating plate 32 of the metal case 31 corresponding to the five tank wall portions 30a to 30e other than the door portion 30f of the six tank wall portions 30 are shown. The faces on the opposite sides are connected in a posture toward the inside of the incubator 16. On the other hand, in the closed state, the door portion 30f is rotatably joined to the metal case 31 corresponding to the left side wall portion 30c by a hinge or the like in a posture in which the reinforcing plate 34 is positioned outside the heat insulating plate 32.
預先將被切斷成與加強板34大致相同平面面積的隔熱板32嵌入地收容在金屬箱體31內，層疊黏接在加強板34上。接著，在隔熱板32上塗敷矽等塗料而形成被覆層36。最後，將由酚醛樹脂等構成的隔熱加強板33層疊在被覆層36的表面(與加強板34相反側的面)上。隔熱加 強板33的形成既可使樹脂板層疊到被覆層36上，也可以將液狀的硬化性樹脂塗敷到被覆層36的表面上使其硬化。反復進行以上作業分別形成6個箱壁部30。但是，對於門部30f專門進行使隔熱加強板33層疊到加強板34與隔熱板32的層疊側之相反側的面上的作業。 The heat shield 32 cut into substantially the same plane area as the reinforcing plate 34 is inserted and housed in the metal case 31 in advance, and is laminated and bonded to the reinforcing plate 34. Next, a coating material such as ruthenium is applied to the heat shield 32 to form a coating layer 36. Finally, a heat insulating reinforcing plate 33 made of a phenol resin or the like is laminated on the surface (surface opposite to the reinforcing plate 34) of the covering layer 36. Insulation plus The strong plate 33 may be formed by laminating a resin plate onto the coating layer 36, or applying a liquid curable resin to the surface of the coating layer 36 to be cured. The above-described operations are repeated to form six tank wall portions 30, respectively. However, the door portion 30f is exclusively subjected to an operation of laminating the heat insulating reinforcing sheets 33 on the surface on the opposite side to the lamination side of the reinforcing sheets 34 and the heat insulating sheets 32.
根據以上說明過的本實施形態的保溫箱16，能夠獲得如下的效果。 According to the incubator 16 of the present embodiment described above, the following effects can be obtained.
(1)6個箱壁部30分別具有由發泡樹脂構成的隔熱板32和金屬製的加強板34層疊構成的面板構造。因此，通過將隔熱板32層疊到加強板34上能夠簡單地形成成為箱壁部30的一塊面板。而且，由於保溫箱16的骨格形狀只要將6個金屬箱體31接合就完成，因此保溫箱16的組裝非常容易。並且，由發泡樹脂構成的隔熱板32的隔熱性能與以往使用的石棉等相比高數倍。因此，各箱壁部30的隔熱性能變高，進而保溫箱16整體的隔熱性能也提高。而且，只要將規定尺寸的隔熱板32層疊到加強板34上就完成隔熱板32的安裝，因此即使在不熟練的作業者進行作業的情況下，保溫箱16的隔熱性能也不容易變得不均勻。 (1) Each of the six tank wall portions 30 has a panel structure in which a heat insulating plate 32 made of a foamed resin and a metal reinforcing plate 34 are laminated. Therefore, a panel which becomes the tank wall portion 30 can be easily formed by laminating the heat shield 32 to the reinforcing plate 34. Further, since the shape of the skeleton of the incubator 16 is completed by joining the six metal cases 31, the assembly of the incubator 16 is very easy. Further, the heat insulating performance of the heat insulating sheet 32 made of a foamed resin is several times higher than that of conventionally used asbestos or the like. Therefore, the heat insulating performance of each of the tank wall portions 30 is increased, and the heat insulating performance of the entire heat insulating box 16 is also improved. Further, if the heat insulating plate 32 of a predetermined size is laminated on the reinforcing plate 34, the mounting of the heat insulating plate 32 is completed, so that the heat insulating performance of the heat insulating box 16 is not easy even if an unskilled operator performs work. It becomes uneven.
(2)6個箱壁部30中，箱壁部30a~30e僅在隔熱板32的裡面層疊有熱傳導率高的金屬加強板34。並且，門部30f僅在隔熱板32的外面層疊有金屬加強板34。因此，在6個箱壁部30的每一個中都能抑制內部的熱量在加強板34中傳導而散發到外部的熱量。即，僅在隔熱板 32的外面有加強板34的情況下，由於保溫箱16內部的高溫空氣不直接與金屬加強板34接觸，熱量僅通過隔熱板32傳遞到外面的加強板34，因此外面的加強板34不會變成高溫，抑制從外面散發的熱能的量。並且，僅在隔熱板32的裡面有加強板34的情況下，雖然由於保溫箱16內部的高溫空氣使得裡面的加強板34變成高溫，但熱傳導被隔熱板32抑制。因此，傳遞到保溫箱16外面的熱能被抑制，從外面散發的熱能的量也受到抑制。 (2) In the six tank wall portions 30, the tank wall portions 30a to 30e are laminated with a metal reinforcing plate 34 having a high thermal conductivity only on the back surface of the heat insulating panel 32. Further, the door portion 30f is laminated with the metal reinforcing plate 34 only on the outer surface of the heat shield 32. Therefore, in each of the six tank wall portions 30, heat that is conducted inside the reinforcing plate 34 and is radiated to the outside can be suppressed. Ie, only on the insulation board In the case where the reinforcing plate 34 is provided outside, since the high-temperature air inside the heat insulating box 16 is not directly in contact with the metal reinforcing plate 34, heat is transmitted only to the outer reinforcing plate 34 through the heat insulating plate 32, so the outer reinforcing plate 34 does not It becomes high temperature and suppresses the amount of heat energy radiated from the outside. Further, in the case where the reinforcing plate 34 is provided only on the inside of the heat insulating plate 32, although the reinforcing plate 34 on the inside becomes high temperature due to the high temperature air inside the heat insulating box 16, the heat conduction is suppressed by the heat insulating plate 32. Therefore, the heat energy transmitted to the outside of the incubator 16 is suppressed, and the amount of heat energy radiated from the outside is also suppressed.
(3)由於加強板34的邊緣部設置有側板35，因此箱壁部30的彎曲剛性變高。尤其是本實施形態中，由於側板35遍及加強板34邊緣部的全周連續地設置，因此金屬箱體31的剛性高，所以箱壁部30的剛性也變得非常高。如此一來，通過提高箱壁部30的剛性，保溫箱16整體的剛性也提高。或者，通過使金屬製加強板34(金屬箱體31)的厚度變薄，也能夠使保溫箱16輕量化。並且，由於側板35從加強板34延伸到隔熱板32的層疊側，因此隔熱板32的側面被側板35遮蓋。尤其是通過在加強板34邊緣部的全周設置側板35，隔熱板32側面的全周被側板35所遮蓋，因此可確實地保護隔熱板32的側面。 (3) Since the side plate 35 is provided at the edge portion of the reinforcing plate 34, the bending rigidity of the box wall portion 30 becomes high. In particular, in the present embodiment, since the side plates 35 are continuously provided over the entire circumference of the edge portion of the reinforcing plate 34, the rigidity of the metal case 31 is high, and therefore the rigidity of the box wall portion 30 is also extremely high. As a result, by increasing the rigidity of the tank wall portion 30, the rigidity of the entire heat insulating box 16 is also improved. Alternatively, the thickness of the metal reinforcing plate 34 (the metal case 31) can be reduced, and the heat insulating box 16 can be made lighter. 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 by the side plate 35. In particular, by providing the side plate 35 over the entire circumference of the edge portion of the reinforcing plate 34, the entire circumference of the side surface of the heat insulating plate 32 is covered by the side plate 35, so that the side surface of the heat insulating plate 32 can be surely protected.
並且，只要將隔熱板32嵌入金屬箱體31的側板35內地收容隔熱板32，就能夠簡單地安裝隔熱板32。並且，隔熱板32相對於加強板34的位置偏離被側板35確實地限制。 Further, if the heat insulating plate 32 is housed by fitting the heat insulating plate 32 into the side plate 35 of the metal case 31, the heat insulating plate 32 can be easily attached. Further, the positional deviation of the heat insulating plate 32 with respect to the reinforcing plate 34 is surely restricted by the side plate 35.
而且，由於加強板34和側板35通過衝壓加工一體成形，因此不需要通過焊接等接合加強板34和側板35的作業，箱壁部30的形成變得更簡單。 Further, since the reinforcing plate 34 and the side plate 35 are integrally formed by press working, the work of joining the reinforcing plate 34 and the side plate 35 by welding or the like is not required, and the formation of the box wall portion 30 becomes simpler.
(4)由於隔熱板32與加強板34相反側的面上層疊有隔熱加強板33，因此隔熱板32與加強板34相反側的面被隔熱加強板33所保護。並且，由於通過設置隔熱加強板33，成為用剛性高的加強板34和隔熱加強板33夾著剛性比較低的隔熱板32的所謂三明治構造，因此能夠提高整體的剛性。另外，隔熱加強板33既可以用板狀構件構成，也可以是塗敷液狀樹脂後硬化的具有剛性的層，其形態沒有特別限制。 (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. In addition, by providing the heat insulating reinforcing plate 33, the so-called sandwich structure in which the heat insulating plate 32 having a relatively low rigidity is sandwiched between the reinforcing plate 34 having high rigidity and the heat insulating reinforcing plate 33 can improve the overall rigidity. Further, the heat insulating reinforcing plate 33 may be formed of a plate-shaped member or a rigid layer which is cured by applying a liquid resin, and the form thereof is not particularly limited.
(5)本實施形態在除去門部30f以外的5個箱壁部30a~30e的每一個中，其加強板34與隔熱板32相反側的面朝向保溫箱16的內側，構成保溫箱16的裡面。金屬製的加強板34與發泡樹脂的隔熱板32或隔熱加強板33相比表面硬度高。即使由於斷絲而纏繞在導絲輥11~15上的絲線Y敲打保溫箱16的裡面，或者導紗時操作者使吸槍碰撞保溫箱16的裡面，裡面也不容易損壞。並且，由於金屬製加強板34的表面平滑，因此即使從絲線Y分離出的油劑和碎絲等塵埃或者污垢附著在保溫箱16的裡面，也容易清掃。另外，在導絲輥11~15的污垢嚴重的情況下，有時用鹼性洗淨液或大量的水清掃。因此保溫箱16的裡面以使用清掃容易並且難以腐蝕的不銹鋼板構成為佳。 (5) In the present embodiment, in each of the five tank wall portions 30a to 30e excluding the door portion 30f, the surface of the reinforcing plate 34 opposite to the heat insulating panel 32 faces the inside of the heat insulating box 16, and constitutes the heat insulating box 16. Inside. The metal reinforcing plate 34 has a higher surface hardness than the heat insulating plate 32 of the foamed resin or the heat insulating reinforcing plate 33. Even if the yarn Y wound on the godet rollers 11 to 15 is broken inside the incubator 16 due to the broken yarn, or when the operator causes the sniffer to collide with the inside of the incubator 16, the inside is not easily damaged. Further, since the surface of the metal reinforcing plate 34 is smooth, even if dust or dirt such as oil or broken yarn separated from the yarn Y adheres to the inside of the heat insulating box 16, it is easy to clean. Further, in the case where the dirt of the godet rollers 11 to 15 is severe, the alkaline washing liquid or a large amount of water may be used for cleaning. Therefore, it is preferable that the inside of the heat insulating box 16 is made of a stainless steel plate which is easy to clean and hard to corrode.
接著，說明對上述實施形態施加種種變更的變更形態。但是，對於具有與上述實施形態同樣構成的部分添加相同的附圖標記適當省略其說明。 Next, a modified form in which various modifications are applied to the above embodiment will be described. However, the same components as those of the above-described embodiment are denoted by the same reference numerals, and their descriptions are omitted as appropriate.
1)箱壁部30的構成能夠例如以下的變更。 1) The configuration of the tank wall portion 30 can be changed, for example, as follows.
上述實施形態中，遍及各箱壁部30的加強板34的邊緣部全周連續地設置側板35，但也可以如圖6(a)所示沿著加強板34的邊緣部彼此隔開間隔地設置多個側板35。 In the above embodiment, the side plates 35 are continuously provided over the entire circumference of the edge portion of the reinforcing plate 34 of each of the tank wall portions 30. However, as shown in Fig. 6(a), the edge portions of the reinforcing plate 34 may be spaced apart from each other as shown in Fig. 6(a). A plurality of side plates 35 are provided.
並且，也可以不在加強板34的邊緣部全周設置側板35。在此情況下，為了確保箱壁部30的彎曲剛性，以在加強體34邊緣部的在與加強板34的面方向平行的方向彼此位於相反側的2個部分上分別設置側板35為佳。例如，圖6(b)在加強板34邊緣部中在短邊方向上彼此位於相反側的2個部分，即加強板34的2條長邊部分上分別設置2塊側板35。即使在該形態下，由於只要將隔熱板32嵌入以2塊側板35劃分出的空間內地收容隔熱板32即可完成該安裝，因此隔熱板32的安裝簡單。並且，藉2塊側板35限制隔熱板32相對於加強板34在加強板34短邊方向上的位置偏離。 Further, the side plate 35 may not be provided over the entire circumference of the edge portion of the reinforcing plate 34. In this case, in order to secure the bending rigidity of the tank wall portion 30, it is preferable to provide the side plates 35 at two portions on the opposite sides of the edge portion of the reinforcing body 34 in the direction parallel to the surface direction of the reinforcing plate 34, respectively. For example, FIG. 6(b) is provided with two side plates 35 on two sides of the edge portion of the reinforcing plate 34 which are located on opposite sides of each other in the short-side direction, that is, two long side portions of the reinforcing plate 34. Even in this form, since the heat insulating plate 32 is fitted into the space defined by the two side plates 35, the heat insulating plate 32 can be accommodated, and the mounting of the heat insulating plate 32 is simple. Further, the positional deviation of the heat insulating plate 32 with respect to the reinforcing plate 34 in the short-side direction of the reinforcing plate 34 is restricted by the two side plates 35.
並且，圖2中，6個箱壁部30中的左側壁部30c、右側壁部30d及後壁部30e的3個箱壁部30中，各自的一部分側部與上壁部30a和下壁部30b抵接。在以上的側部中，隔熱板32並無以側板35遮蓋的必要。即，如圖2的保溫箱16，尤其是在左側壁部30c、右側壁部30d及後壁 部30e的3個箱壁部30能夠適當採用圖6(b)的構成。 Further, in FIG. 2, among the three tank wall portions 30c of the left side wall portion 30c, the right side wall portion 30d, and the rear wall portion 30e of the six tank wall portions 30, a part of the side portions and the upper wall portion 30a and the lower wall are respectively provided. The portion 30b abuts. In the above side portions, the heat insulating plate 32 is not required to be covered by the side plates 35. That is, the incubator 16 of FIG. 2, in particular, the left side wall portion 30c, the right side wall portion 30d, and the rear wall The three tank wall portions 30 of the portion 30e can adopt the configuration of Fig. 6(b) as appropriate.
並且，如圖6(c)所示，側板35也可以從加強板34延伸到與隔熱板32層疊側的相反側。並且，如圖6(d)所示，為了提高加強板34(金屬箱體31)的扭轉剛性，也可以連結加強板34對角地設置加強肋39。另外，圖6(d)中，4塊隔熱板32分別被收容到金屬箱體31內的由2條加強肋39所分隔的4個空間內。 Further, as shown in FIG. 6(c), the side plate 35 may extend from the reinforcing plate 34 to the side opposite to the side on which the heat insulating plate 32 is laminated. Further, as shown in FIG. 6(d), in order to increase the torsional rigidity of the reinforcing plate 34 (the metal case 31), the reinforcing ribs 39 may be provided diagonally to the reinforcing plate 34. Further, in FIG. 6(d), the four heat insulating panels 32 are housed in the four spaces partitioned by the two reinforcing ribs 39 in the metal casing 31.
並且，上述實施形態中雖公開了通過對一塊金屬板實施衝壓加工一體形成加強板34和側板35的例子，但也可以將一塊金屬板彎折，根據需要在四角實施焊接形成加強板34和側板35。或者，也可以藉由螺栓或焊接等將與該加強板34不同的板，即側板35接合到加強板34上。 Further, in the above-described embodiment, an example in which the reinforcing plate 34 and the side plate 35 are integrally formed by press working on one metal plate is disclosed. However, one metal plate may be bent, and welding may be performed at four corners as needed to form the reinforcing plate 34 and the side plate. 35. Alternatively, the plate different from the reinforcing plate 34, that is, the side plate 35 may be joined to the reinforcing plate 34 by bolting or welding.
並且，也可以如圖6(e)所示不在加強板34的邊緣部設置側板35，僅在加強板34層疊隔熱板32。另外，此情況下，為了使隔熱板32不相對於加強板34位置偏離，以使用黏接劑或螺栓等將隔熱板32固定在加強板34為佳。 Further, as shown in FIG. 6(e), the side plate 35 may not be provided at the edge portion of the reinforcing plate 34, and the heat insulating plate 32 may be laminated only on the reinforcing plate 34. Further, in this case, in order to prevent the heat shield 32 from being displaced from the reinforcing plate 34, it is preferable to fix the heat shield 32 to the reinforcing plate 34 by using an adhesive or a bolt.
2)上述實施形態中，如圖3、圖4所示在隔熱板32的與加強板34相反側的面層疊有隔熱加強板33，但也可以省略該隔熱加強板33。 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. However, the heat insulating reinforcing plate 33 may be omitted.
3)上述實施形態中，針對除門部30f以外的5個箱壁部30a~30e，加強板34的與隔熱板32相反側的面朝著保溫箱16的內側，另一方面，對於門部30f加強板34是配置在比隔熱板32更外側。對此，針對各箱壁部30的姿 勢(朝向)並無特別地限制。例如，也可以在包括門部30f的所有箱壁部30中，使加強板34朝向內側。 3) In the above embodiment, the faces of the reinforcing plate 34 on the opposite side to the heat insulating plate 32 are directed toward the inside of the heat insulating box 16 for the five tank wall portions 30a to 30e except the door portion 30f. The portion 30f reinforcing plate 34 is disposed outside the heat insulating plate 32. In this regard, the posture of each box wall portion 30 The potential (orientation) is not particularly limited. For example, the reinforcing plate 34 may be directed inward in all of the tank wall portions 30 including the door portion 30f.
或者，也可以在門部30f以外的箱壁部30中，加強板34配置在比隔熱板32的更外側。尤其在某個箱壁部30中安裝有某構造體的情況下，對該箱壁部30為維持隔熱板32外側安裝附帶零組件的強度，或者通過選定使柔軟的發泡樹脂製的隔熱板32不露出到外側以使得加強板34位在比隔熱板32的更外側為佳。 Alternatively, the reinforcing plate 34 may be disposed outside the heat insulating plate 32 in the tank wall portion 30 other than the door portion 30f. In particular, when a certain structure is attached to one of the tank wall portions 30, the tank wall portion 30 is provided with a strength to which the components are attached to the outside of the heat insulating panel 32, or a partition made of a soft foamed resin is selected. The hot plate 32 is not exposed to the outside so that the reinforcing plate 34 is positioned outside the heat insulating plate 32.
4)對於收容在保溫箱16內的加熱輥的構成不加以特別限制。例如也可以是上述專利文獻1中揭示的加熱輥的構成。即，如圖7所示在保溫箱46內收容具有內部加熱器42的加熱輥的導絲輥43和非加熱輥的分離輥44。從保溫箱46的絲線導入口46a導入的多根絲線Y多次捲繞在導絲輥43與分離輥44之間。通過與導絲輥43接觸被加熱的多根絲線Y從保溫箱46的絲線匯出口46b被送往下游側。 4) The configuration of the heating roller housed in the incubator 16 is not particularly limited. For example, the configuration of the heating roller disclosed in Patent Document 1 above may be employed. That is, as shown in FIG. 7, the godet roller 43 of the heating roller having the internal heater 42 and the separation roller 44 of the non-heating roller are housed in the incubator 46. The plurality of yarns Y introduced from the wire introduction port 46a of the heat insulating box 46 are wound between the godet roller 43 and the separation roller 44 a plurality of times. The plurality of heated yarns Y in contact with the godet roller 43 are sent from the wire outlet 46b of the incubator 46 to the downstream side.
5)上述實施形態為構成保溫箱16的6個箱壁部30全部具有由金屬製的加強板34和側板35構成的金屬箱體31和由發泡樹脂構成的隔熱板32的構成。與此不同，也可以是6個箱壁部30中的一部分具有與上述不同的構造。例如，也可以6個箱壁部30中除門部30f以外的5個箱壁部30a~30f採用加強板34和隔熱板32的層疊構造，而對於還要求保溫功能以外的不同功能(例如操作者的操作性)的門部30f則重視輕量化等而採用不同的構 造。 (5) In the above embodiment, all of the six tank wall portions 30 constituting the heat insulating box 16 have a metal case 31 made of a metal reinforcing plate 34 and a side plate 35, and a heat insulating plate 32 made of a foamed resin. On the other hand, a part of the six tank wall portions 30 may have a structure different from the above. For example, the five tank wall portions 30a to 30f other than the door portion 30f of the six tank wall portions 30 may have a laminated structure of the reinforcing plate 34 and the heat insulating panel 32, and different functions other than the heat insulating function may be required (for example) The door portion 30f of the operator's operability is emphasized in terms of weight reduction and the like. Made.
