Description

本発明は、製造工程中に発生する不良品となる廃棄用光ファイバを巻取る巻取りドラムに関する。   The present invention relates to a winding drum that winds up a waste optical fiber that becomes a defective product generated during a manufacturing process.

一般に光ファイバは、所定の太さに作られたガラス母材を加熱炉で加熱しながら軟化させ、例えば、糸の径まで引き伸ばす。引き伸ばされたファイバ芯線は冷却され、コーティング用樹脂で被覆された後、巻取りドラムによって巻取られる。   In general, an optical fiber is softened while being heated in a heating furnace with a glass base material having a predetermined thickness, and is stretched to the diameter of the yarn, for example. The stretched fiber core wire is cooled, coated with a coating resin, and then wound around a winding drum.

これら一連の製造工程においてファイバ芯線に径の異なる径変が発生したり、あるいは、ガラス母材製造中に泡が混入すると、その泡はファイバ芯線にする時に何百メートル、時として何キロメートルにわたって引き伸ばされ、それが不良品となって現れる。   If a diameter change occurs in the fiber core wire during these series of manufacturing processes, or bubbles are mixed in during the production of the glass preform, the bubbles are stretched over hundreds of meters and sometimes kilometers over the fiber core. It appears as a defective product.

このような場合、例えばガラス母材中に泡の混入が見つかった時には、一般の製品用の巻取りドラムから廃棄用の巻取りドラムに交換して巻取り、廃棄処分するようにしている。   In such a case, for example, when mixing of bubbles is found in the glass base material, the winding drum for a general product is replaced with a winding drum for disposal, and is wound for disposal.

廃棄用の巻取りドラムは、光ファイバを巻取る巻取り装置をそのまま利用するところから、強い張力が働いた状態で巻取られる。   The winding drum for disposal is wound in a state where a strong tension is applied, since the winding device for winding the optical fiber is used as it is.

したがって、廃棄処分する時に巻取りドラムに巻取られた光ファイバは強く巻き付き、取外すのに多大の労力と時間を必要とするところから、それを解消するために、光ファイバが容易に巻取りドラムから取外せる手段が既に公知となっている。
特開平７−１７６７１号公報 Therefore, the optical fiber wound around the winding drum when it is disposed of is strongly wound and requires a lot of labor and time to remove it. Means that can be removed from the are already known.
JP 7-17671 A

光ファイバの取外しを容易とした巻取りドラムの概要は、撓曲性の材料から成る中空円柱状の胴部を予め巻取りドラムのドラムに対して取外し自在に装着しておき、その上から光ファイバを巻取るものである。それを取外すには、ドラムに設けられた一方の鍔部を取外し、続いて光ファイバが巻かれた胴部ごとドラムから取外す手段となっている。   The outline of the winding drum that facilitates the removal of the optical fiber is as follows. A hollow cylindrical body made of a flexible material is attached in advance to the drum of the winding drum so that it can be detached. The fiber is wound up. In order to remove it, one of the flanges provided on the drum is removed, and then the whole body around which the optical fiber is wound is removed from the drum.

胴部と一緒に取外された光ファイバは、前記胴部に上から力を加え変形させることで、胴部から光ファイバが引離され、取外しが容易となる。反面、この手段は撓曲性の胴部を別途必要とするためコストの面で望ましくない。この場合、撓曲性の胴部の使用をやめて、例えば、取外し易いように着脱可能とした一方の鍔部側へ向かって巻取りドラムのドラムを下降傾斜するテーパ面とする手段が考えられるが、巻取り装置によって動力で巻取られた光ファイバは強く、きつく巻取られ、結果的にはテーパ面があっても実際には取外すことができないのが現状となっている。   The optical fiber removed together with the body part is deformed by applying a force to the body part from above, so that the optical fiber is pulled away from the body part and can be easily removed. On the other hand, this means is not desirable in terms of cost because it requires a separate flexible body. In this case, it can be considered that the use of the flexible body portion is stopped, for example, a taper surface in which the drum of the take-up drum is inclined downward toward the one heel portion side which can be detached for easy removal. However, the optical fiber wound by power by the winding device is strong and tightly wound, and as a result, even if there is a taper surface, it cannot be actually removed.

そこで、本発明にあっては、巻取り用の胴部に強く、きつく巻付いた光ファイバを容易に取外せるようにした廃棄用光ファイバの巻取りドラムを提供することを目的としている。   Accordingly, an object of the present invention is to provide a waste optical fiber take-up drum that is strong against a take-up body and that can easily remove a tightly wound optical fiber.

前記目的を達成するために、本発明にあっては、巻取り胴部と、その巻取り胴部の一方に設けられその巻取り胴部と一体の円板状の固定用鍔部と、巻取り胴部の他方に設けられその巻取り胴部に対して取付け、取外し可能な円板状の可動用鍔部と、前記巻取り胴部の周方向の一部領域で前記固定用鍔部から可動用鍔部にわたって取外し自在に形成された取外し胴部とから成り、前記可動用鍔部は、前記巻取り胴部から前記可動用鍔部を取外した時、軸方向に沿って前記取外し胴部の取外しを可能とし、巻取り胴部に取付けた時、前記取外し胴部の動きを拘束する拘束手段を兼ね備えることを特徴とする。   In order to achieve the above-mentioned object, in the present invention, a winding drum portion, a disk-shaped fixing hook provided on one of the winding drum portions and integral with the winding drum portion, A disc-shaped movable saddle that is provided on the other side of the take-up drum and can be attached to and removed from the take-up drum and a part of the take-up drum in the circumferential direction from the fixing hook. A detachable body portion formed detachably over the movable heel portion, and the detachable body portion when the movable heel portion is removed from the winding body portion along the axial direction. And a restraining means for restraining the movement of the detaching body part when it is attached to the winding body part.

本発明の廃棄用光ファイバの巻取りドラムによれば、巻取られた光ファイバは取外し胴部に接触する作用面積は小さくて済むため可動用鍔部を取外すことで取外し胴部を、大きな抵抗を受けることなく容易に取外すことができる。この結果、巻取り胴部の周方向の一部領域に作られた大きな隙間空間によって、きつく巻取られた光ファイバに弛みが生じ、巻取り胴部から容易に取外せるようになる。   According to the waste optical fiber winding drum of the present invention, since the wound optical fiber requires only a small area of contact with the detachable barrel portion, the removal barrel portion has a large resistance by removing the movable hook portion. Can be easily removed without receiving. As a result, the tightly wound optical fiber is slackened by the large gap space formed in a partial region in the circumferential direction of the winding drum, and can be easily removed from the winding drum.

前記巻取り胴部の周方向の一部分に大きな隙間空間を作り、巻取り胴部にきつく巻取られた光ファイバの巻取に弛みを生じさせるという目的を、前記巻取り胴部の周方向の一部領域で、固定用鍔部から可動用鍔部にわたって取外し可能な取外し胴部によって達成する。   The purpose of creating a large gap space in a part of the winding drum portion in the circumferential direction and causing slack in the winding of the optical fiber tightly wound on the winding drum portion is the circumferential direction of the winding drum portion. In some areas, this is achieved by a removable barrel that can be removed from the fixed collar to the movable collar.

（実施例１）
以下、図１乃至図７の図面を参照しながら本発明の実施形態について具体的に説明する。 Example 1
Hereinafter, embodiments of the present invention will be specifically described with reference to FIGS. 1 to 7.

図１は本発明にかかる廃棄用光ファイバの巻取りドラムの分解斜視図、図２は巻取りドラムの斜視図をそれぞれ示している。   FIG. 1 is an exploded perspective view of a winding optical fiber winding drum according to the present invention, and FIG. 2 is a perspective view of the winding drum.

巻取りドラム１は、巻取り胴部３の一方に設けられた円板状の固定用鍔部５と、他方に設けられた円板状の可動用鍔部７とかな成り、合成樹脂の材質で作られている。   The winding drum 1 is composed of a disc-shaped fixing collar 5 provided on one side of the winding drum 3 and a disk-shaped movable collar 7 provided on the other, and is made of a synthetic resin. It is made with.

巻取り胴部３は、一部領域にわたって取外し可能な取外し胴部９とその内側に径の小さい筒状の軸筒部１１とを有している。内側の軸筒部１１と巻取り胴部３とは中央部位に設けられた連結部材となるフランジ部１３を介して一体に連結支持されている。   The winding drum portion 3 has a detachable drum portion 9 that can be removed over a partial area, and a cylindrical shaft tube portion 11 having a small diameter inside thereof. The inner shaft cylinder portion 11 and the winding drum portion 3 are integrally connected and supported via a flange portion 13 serving as a connecting member provided at the central portion.

取外し胴部９の周方向の長さＬは、実験の結果、前記巻取り胴部３の軸線を中心として９０度ずつ４つに分割したその１つの分割領域の円弧面が、最適となっているが、その長さより若干短くても可能である。また、取外し胴部９の軸方向の長さＤは、前記固定用鍔部５から可動用鍔部７までとなっていて、後述する可動用鍔部７を取外すことで、その可動用鍔部７側からの取外しが可能となっている。   As a result of the experiment, the length L in the circumferential direction of the detaching body 9 is optimally the arc surface of the one divided region divided into four 90 degrees around the axis of the winding body 3. However, it may be slightly shorter than the length. Further, the axial length D of the detachable body portion 9 is from the fixing collar portion 5 to the movable collar portion 7, and the movable collar portion can be obtained by removing the movable collar portion 7 described later. Removal from the 7 side is possible.

この場合、図１に示すように、巻取り胴部３と軸筒部１１とをつなぐフランジ部１３に前記取外し胴部９の領域にわたって切断領域１３ａを設け、不良品となった光ファイバを巻取り胴部３から取外す時に手等が干渉しないようにすることが望ましい。   In this case, as shown in FIG. 1, a cut region 13 a is provided over the region of the detachable barrel portion 9 in the flange portion 13 that connects the winding barrel portion 3 and the shaft tube portion 11, and a defective optical fiber is wound. It is desirable to prevent hands from interfering when removing from the take-up drum section 3.

固定用鍔部５は、図５に示すように前記巻取り胴部３及び内側の軸筒部１１と一体に形成されると共に、中心部位には軸孔１５が設けられている。軸孔１５の中心軸線と前記軸筒部１１の中心軸線Ｘとは同一軸線上に設定され、軸孔１５と軸筒部１１とは一体に連続し会う形状となっている。   As shown in FIG. 5, the fixing flange 5 is formed integrally with the take-up drum portion 3 and the inner shaft cylinder portion 11, and a shaft hole 15 is provided at the central portion. The center axis line of the shaft hole 15 and the center axis line X of the shaft tube part 11 are set on the same axis line, and the shaft hole 15 and the shaft tube part 11 are formed so as to be continuously integrated.

可動用鍔部７は、中心部位に前記固定用鍔部５側の軸孔１５と対応する軸孔１７ａを備えた軸孔嵌合筒部１７と外側嵌合筒部１９とを有している。軸孔嵌合筒部１７は前記軸筒部１１の端縁部と突合せることで所定の嵌合代を有して着脱自在に結合しており、前記軸筒部１１と軸孔嵌合筒部１７は、図外の巻取り装置のシャフトに対して装着可能となっている。可動用鍔部７の外側嵌合筒部１９は、リング状に短く突出した形状となっていて前記巻取り胴部３に対して突合せることで、前記取外し胴部９を含めて巻取り胴部３の内周面に所定の嵌合代を有して着脱自在に嵌合するようになっている。加えて、可動用鍔部７は、前記巻取り胴部３から取外した時、前記取外し胴部９の取外しを可能とし、巻取り胴部３に取付けた時、取外し胴部９の動きを拘束する拘束手段を兼備える手段となっている。   The movable collar part 7 has a shaft hole fitting cylinder part 17 and an outer fitting cylinder part 19 provided with a shaft hole 17a corresponding to the shaft hole 15 on the fixing collar part 5 side at the center part. . The shaft hole fitting cylinder part 17 is detachably coupled with a predetermined fitting allowance by abutting with the end edge part of the shaft cylinder part 11, and the shaft cylinder part 11 and the shaft hole fitting cylinder are connected. The part 17 can be attached to a shaft of a winding device (not shown). The outer fitting cylinder portion 19 of the movable collar portion 7 has a shape that protrudes short in a ring shape, and is brought into contact with the winding drum portion 3 so that the winding drum including the detaching drum portion 9 is included. The inner peripheral surface of the portion 3 is detachably fitted with a predetermined fitting allowance. In addition, the movable eaves part 7 enables the removal body part 9 to be removed when it is removed from the winding body part 3, and restrains the movement of the removal body part 9 when attached to the winding body part 3. It is a means which combines the restraining means to do.

具体的に説明すると、取外し胴部９の内側に前記固定用鍔部５の内壁面に沿って係合し合う第１係合フランジ部２１と前記可動用鍔部７の外側嵌合筒部１９の内壁面に沿って係合し合う第２係合フランジ部２３がそれぞれ設けられている。   More specifically, a first engagement flange portion 21 that engages along the inner wall surface of the fixing flange portion 5 and an outer fitting cylinder portion 19 of the movable flange portion 7 inside the removal barrel portion 9. Second engaging flange portions 23 that engage with each other along the inner wall surface are provided.

この場合、第２係合フランジ部２３と可動用鍔部７との係合関係がすぐに目視によって判別できるように、図１、図２に示す如く、それぞれに位置合せ用のマークＲをつけることが望ましい。   In this case, as shown in FIG. 1 and FIG. 2, each of the alignment marks R is provided so that the engagement relationship between the second engagement flange portion 23 and the movable flange portion 7 can be immediately discriminated visually. It is desirable.

一方、前記巻取り胴部３の内壁面には、その内壁面に沿ってリング状に嵌合し合う可動用鍔部７の外側嵌合筒部１９を内側から保持する保持フランジ２５が１８０度対向し合う位置にそれぞれ２箇所設けられている。   On the other hand, on the inner wall surface of the winding drum portion 3, a holding flange 25 for holding the outer fitting cylinder portion 19 of the movable collar portion 7 fitted in a ring shape along the inner wall surface from the inside is 180 degrees. Two positions are provided at positions facing each other.

２箇所の保持リング２５は、アングル状に形成された一方向への回転を阻止する回転規制面２７と軸方向への動きを阻止する抜け止め規制面２９とを有する一方、可動用鍔部７の外側嵌合筒部１９には、係合ロック部３１ａを有するアングル状の係合ストッパ３１が１８０度対向し合う位置にそれぞれ２箇所設けられている。   The two holding rings 25 have a rotation restricting surface 27 that prevents rotation in one direction formed in an angle shape, and a retaining restricting surface 29 that prevents movement in the axial direction, while the movable collar 7 The outer fitting tube portion 19 is provided with two angled engagement stoppers 31 each having an engagement lock portion 31a at positions facing each other by 180 degrees.

したがって、可動用鍔部７を巻取り胴部３に取付ける時に、図６（ａ）に示すように、係合ストッパ３１を巻取り胴部３の保持リング２５に対して偏位させた状態で外側嵌合筒部１９を巻取り胴部３に嵌合させた後、（二点線鎖線）係合ロック部３１ａが前記保持リング２５に設けられた回転規制面２７に当るまで前記可動用鍔部７を回転（二点線鎖線矢印）させることで、図６（ｂ）に示すように係合ロック部３１ａと保持リング２５の抜け止め規制面２９とが噛み合い、軸方向（矢印イ）への動きが拘束されるようになっている。   Therefore, when the movable collar 7 is attached to the winding drum 3, the engagement stopper 31 is displaced with respect to the holding ring 25 of the winding drum 3, as shown in FIG. After the outer fitting cylinder portion 19 is fitted to the winding drum portion 3, the movable collar portion is moved until the (two-dot chain line) engagement lock portion 31 a hits the rotation regulating surface 27 provided on the holding ring 25. 7 is rotated (two-dot chain line arrow), the engagement locking portion 31a and the retaining prevention surface 29 of the retaining ring 25 are engaged with each other as shown in FIG. 6B, and the movement in the axial direction (arrow A) Is to be restrained.

これにより、取外し胴部９は、周方向及び軸方向への動きが確実に拘束された状態が確保されるようになる。   Thereby, the removal trunk | drum 9 comes to ensure the state to which the movement to the circumferential direction and the axial direction was restrained reliably.

このように構成された廃棄用の巻取りドラム１によれば、不良品が発見された時には、製品用の巻取りドラムにかえて廃棄用の巻取りドラム１に交換することで、不良品となった光ファイバを巻取ることができる。   According to the waste winding drum 1 configured as described above, when a defective product is found, it is replaced with a waste winding drum 1 in place of the product winding drum. The resulting optical fiber can be wound up.

次に、廃棄用の巻取りドラム１によって巻取られた光ファイバを取外すには、可動用鍔部７を回転させて係合ロック部３１ａを保持リング２５の抜け止め規制面２９から後退させて噛み合いを解除（図６（ｂ））することで可動用鍔部７を巻取り胴部３から取外せるようになる。   Next, in order to remove the optical fiber taken up by the waste take-up drum 1, the movable hook portion 7 is rotated to retract the engagement lock portion 31 a from the retaining prevention surface 29 of the holding ring 25. By releasing the meshing (FIG. 6B), the movable collar 7 can be detached from the winding drum 3.

次に、取外し胴部９を、取外された前記可動用鍔部７側へ向け引張ることで、取外せる。この時、取外し胴部９には光ファイバが接触する作用面積が小さくて済むため、大きな抵抗を受けることなく容易に取外せると共に、巻取り胴部３の一部分に大きな隙間空間が作られるようになる。この隙間空間は図７に示すように巻取り面となる円弧面３ａから二点鎖線で示す直線面３ｂとなるため、その差分、光ファイバの弛みとなって現れ、巻取り胴部３から容易に取外せるようになる。   Next, the removal trunk | drum 9 can be removed by pulling toward the said movable collar part 7 side removed. At this time, since the working area with which the optical fiber comes into contact with the removal barrel 9 is small, it can be easily removed without receiving a large resistance, and a large gap space is created in a part of the winding barrel 3. Become. As shown in FIG. 7, the gap space changes from a circular arc surface 3 a serving as a winding surface to a straight surface 3 b indicated by a two-dot chain line. Can be removed.

一方、不良品となった光ファイバを取外した後は、まず、先に取外し胴部９を巻取り胴部３に組付け、続いて可動用鍔部７を取付けることで、再び廃棄用巻取りドラム１としての使用が可能となり、繰返し使用できる。   On the other hand, after removing the defective optical fiber, first, the removal body is assembled first, and then the body 9 is assembled to the wind-up body 3, and then the movable hook 7 is attached, so that the winding for disposal is again performed. It can be used as the drum 1 and can be used repeatedly.
