献をした。 In recent years, in order to increase the spinning speed and to save energy in the production of artificial fibers, there has been a need for spinning pots that are lightweight, strong, and chemically resistant. As proposals to meet these demands, methods described in Japanese Patent Publication No. 47-36206, Japanese Patent Publication No. 53-44570, and Japanese Patent Application Laid-open No. 15406-1982 are known. As shown in FIG. 1 (longitudinal cross-sectional view of the pot), the pot manufactured by these methods includes a pot bottom insert 1 made of a chemical-resistant material and, for example,
Glass fibers, carbon fibers, aromatic polyamide fibers, etc. impregnated with an acid-resistant thermosetting resin such as epoxy resin are wound in diagonal or almost parallel layers multiple times, the resin is cured, and the fibers are potted. It forms the main body 2. The pots manufactured in this way were lighter and more resistant to acid than the conventional Bakelite pots reinforced with piano wire, making a significant contribution to energy savings.
しかし、一方では、従来のベークライト製ポツ
トにはない欠点を有していた。つまり、ポツト底
部とポツト側壁接点の強度が他の部分に比べて弱
く、しかも紡糸用ポツトの性質上、8000〜10000
回転／分という超高速回転で用いるため、ごくわ
ずかのポツト側壁の真円度の誤差によつてポツト
のこの部分に大きな力が加わるため、ポツト断面
形が、長方形から平行四辺形になる様な変形をお
こすという欠点を有していた。 However, on the other hand, it had drawbacks that conventional Bakelite pots did not have. In other words, the strength of the contact between the bottom of the pot and the side wall of the pot is weak compared to other parts, and due to the nature of the spinning pot,
Since the pot is used at extremely high speeds of rotation per minute, a small error in the roundness of the side wall of the pot will cause a large force to be applied to this part of the pot, causing the cross-sectional shape of the pot to change from a rectangle to a parallelogram. It had the disadvantage of causing deformation.
本発明者らは、ポツト底部のインサートを特殊
に形成することで、前述のごとき、変形をおこし
にくいポツトが製作できることを見出した。 The present inventors have discovered that by specially forming the insert at the bottom of the pot, it is possible to manufacture a pot that is less likely to deform as described above.
本発明の目的は、前述の如き、問題点を解決し
た紡糸用ポツトを提供することにある。 An object of the present invention is to provide a spinning pot that solves the above-mentioned problems.
また、本発明の目的を達成する要旨は、繊維状
補強材によつて強化された熱硬化性樹脂製の紡糸
用ポツトにおいて、予め成形されたインサート１

ート１の底面５の円周部分６が上方に突起してな
ることを特徴とする紡糸用ポツトである。 Moreover, the gist of achieving the object of the present invention is that in a spinning pot made of a thermosetting resin reinforced with a fibrous reinforcing material, a preformed insert 1 is used.
This spinning pot is characterized in that the insert 1 is fixedly installed in the pot side wall 4, and the circumferential portion 6 of the bottom surface 5 of the insert 1 projects upward.
次に、本発明の紡糸用ポツトの実施態様を一実
施例を示す図面によつて説明する。 Next, embodiments of the spinning pot of the present invention will be described with reference to drawings showing one embodiment.
第２図は、本発明による紡糸用ポツトの構造を

周部分６に突起７を形成している。この実施例で
は突起７をリング状に形成した。他に櫛状に形成
してもよい。 FIG. 2 is a sectional view showing the structure of a spinning pot according to the present invention. In the figure, the insert 1 is made of a chemical-resistant material such as Bakelite, has an inverted triangular shape, and has a protrusion 7 formed on a circumferential portion 6 of the bottom surface 5 of the insert. In this embodiment, the protrusion 7 is formed into a ring shape. Alternatively, it may be formed into a comb shape.
このインサート１を底部として、これに熱硬化
性樹脂を含浸させた繊維状補強材３を複数回巻き
付けた後、前述の熱硬化性樹脂を硬化させてポツ
ト本体３を形成する。この際、インサート１はポ
ツト側壁４内に固設される。 Using this insert 1 as the bottom, a fibrous reinforcing material 3 impregnated with a thermosetting resin is wrapped around it multiple times, and then the thermosetting resin is cured to form the pot body 3. At this time, the insert 1 is fixedly installed within the pot side wall 4.
繊維状補強材３としては、強度、耐酸性を考慮
して、炭素繊維、芳香族ポリアミド繊維単体、も
しくは両者の混合繊維を用いるのが好ましい。 As the fibrous reinforcing material 3, in consideration of strength and acid resistance, it is preferable to use carbon fiber, aromatic polyamide fiber alone, or a mixed fiber of both.
また、インサート底面５の円周部分突起７の高
さを、インサート底面５より10mm以上とすること
が好ましい。10mm以下では本発明の目的とする効
果が薄い。８はポツトカバーである。 Further, it is preferable that the height of the circumferential protrusion 7 on the insert bottom surface 5 is 10 mm or more higher than the insert bottom surface 5. If the thickness is less than 10 mm, the desired effect of the present invention will be weak. 8 is a pot cover.
本発明者らは、前記した突起７の高さを変えて
ポツトを製作し、ポツトの回転数8000回転／分で
336時間連続運転して、運転後のポツト先端の最
大振れ巾を測定した。得られた結果を第３図に示
す。第３図より、突起７の高さをインサート底面
５より10mm以上形成するとポツト先端の最大振れ
巾が極めて小さくなることが解る。 The present inventors manufactured a pot by changing the height of the protrusion 7 described above, and the pot was rotated at a rotation speed of 8000 revolutions/minute.
After continuous operation for 336 hours, the maximum swing width of the tip of the pot was measured. The results obtained are shown in FIG. From FIG. 3, it can be seen that when the height of the protrusion 7 is formed to be 10 mm or more higher than the bottom surface 5 of the insert, the maximum swing width of the tip of the pot becomes extremely small.
このことにより、ポツト底部とポツト側壁接点
の強度が強化され、ポツトを超高速回転で用いて
も、ポツト断面形が平行四辺形様に変形すること
がなくなる効果を生むのである。 This strengthens the strength of the contact between the bottom of the pot and the side wall of the pot, and produces the effect that the cross-sectional shape of the pot does not deform into a parallelogram even when the pot is rotated at extremely high speeds.
また、従来、ポツト内に巻き取られたケークに
ついては、そを端面と円周部分の接続付近に毛羽
が発生し易いという欠点があつたが、本発明によ

形した後、この部分に接するケークの毛羽発生を
おさえるという効果も生ずるのである。 Furthermore, conventionally, the cake rolled up in the pot had the disadvantage that fuzz was easily generated near the connection between the end face and the circumferential part, but in the pot according to the present invention, the protrusion 7 is formed in advance during insert molding. It is possible to finish the inner surface of the pot, which also has the effect of suppressing the formation of fuzz on the cake that comes into contact with this portion after being formed into a pot.
このように、本発明によれば強度が向上し、超
高速回転で用いても変形をおこすことのない人造
繊維紡糸用ポツトを提供するものである。 As described above, the present invention provides an artificial fiber spinning pot which has improved strength and does not undergo deformation even when used at ultra-high speed rotation.
