Description

巻芯固定手段9は、環状本体8の円周方向の少なくとも3箇所に形成した、中心駆動軸2の回転方向に次第に深くなる底面傾斜溝11と、環状本体8に被せた巻芯Cの内周面に係合可能な、環状本体8の中心軸線方向に平行に伸長した係合部12aを有する、底面傾斜溝11に個別に配置した複数の可動体12と、この複数の可動体12を、夫々底面傾斜溝8の浅い部分と深い部分の間を移動可能かつ脱落不能に相互間隔を維持して保持する、環状本体8の外周に回転可能に嵌めた環状のリテーナ13と、環状本体8の外周に巻芯Cを装着していないとき各可動体12が、該各可動体12の係合部12aに外接する円の直径が巻芯Cの内径より大きくなる待機位置に復帰するようリテーナ13に回転力を付与するための、リテーナ13と環状本体8との間に設けた、弾力的に伸縮可能な伸縮部材14とからなる。 The core fixing means 9 includes a bottom inclined groove 11 formed in at least three locations in the circumferential direction of the annular main body 8 and gradually deepening in the rotation direction of the central drive shaft 2, and an inner core C covering the annular main body 8. A plurality of movable bodies 12 individually arranged in the bottom inclined groove 11, each having an engagement portion 12 a extending in parallel with the central axis direction of the annular main body 8, which can be engaged with the peripheral surface, and the plurality of movable bodies 12. An annular retainer 13 rotatably fitted on the outer periphery of the annular body 8 that is movable between a shallow portion and a deep portion of the bottom inclined groove 8 and is held so as not to fall off. When the winding core C is not attached to the outer periphery of each of the movable bodies 12, each movable body 12 is returned to a standby position where the diameter of the circle circumscribing the engaging portion 12a of each movable body 12 is larger than the inner diameter of the winding core C. Retainer 13 and ring for applying rotational force to 13 Provided between the body 8 consists resiliently stretchable elastic member 14.

巻芯アダプター群位置決め手段7は、この実施例では巻取カラー群4上において巻芯アダプター群6を挟むよう巻取カラー群4上の所定位置に配置した左右の位置決め環25、26からなる。左右の位置決め環25及び26は夫々巻取カラー群4に着脱自在であり、左側の位置決め環25は、中心駆動軸2の左側の端部付近の外周面2aに嵌めてあり、その左側の端部は中心駆動軸2の段付部2bの肩に当接している。そのため、位置決め環25は、巻芯アダプター群6に右側の位置決め環26から軸線方向に作用する押圧力に抗して巻芯アダプター群6の左側への移動を阻止することができる。左側の位置決め環25と巻芯アダプター群6との間にはスペーサ27が嵌めてある。右側の位置決め環26は、巻取カラー群4の外周に装着してあり、その左側の端部には、巻芯アダプター5と同様のころがり軸受28が装着してある。また、巻取中、スペーサ29を介して、環状の押圧部材30から押圧力を受け、巻芯アダプター群6を押圧した状態を維持することができる。押圧部材30は可動腕31の先端部に装着してある。また可動腕31は、流体圧シリンダ装置32により中心駆動軸2の長手方向に適時押し引き可能に設けてある。流体圧シリンダ装置32により可動腕32を所定の力で押すと、スペーサ27を介して位置決め環26が巻芯アダプター群6に押付けられる。それによって、位置決め環25と位置決め環26は巻芯アダプター群を所定の位置に位置決めすると共に、所定の押圧力を巻芯アダプター群6に付与することができる。なお巻取条件等によってはスペーサ27やスペーサ29が不要の場合もあり得る。 In this embodiment, the core adapter group positioning means 7 includes left and right positioning rings 25 and 26 arranged at predetermined positions on the winding collar group 4 so as to sandwich the core adapter group 6 on the winding collar group 4. The left and right positioning rings 25 and 26 are detachably attached to the winding collar group 4, respectively, and the left positioning ring 25 is fitted to the outer peripheral surface 2a near the left end of the center drive shaft 2, and the left end thereof The portion is in contact with the shoulder of the stepped portion 2 b of the center drive shaft 2. Therefore, the positioning ring 25 can prevent the core adapter group 6 from moving to the left against the pressing force acting in the axial direction from the right positioning ring 26 on the core adapter group 6 . A spacer 27 is fitted between the left positioning ring 25 and the core adapter group 6. The right positioning ring 26 is mounted on the outer periphery of the winding collar group 4, and a rolling bearing 28 similar to the core adapter 5 is mounted on the left end thereof. Further, during winding, it is possible to maintain a state where the core adapter group 6 is pressed by receiving a pressing force from the annular pressing member 30 via the spacer 29. The pressing member 30 is attached to the distal end portion of the movable arm 31. The movable arm 31 is provided so as to be able to be pushed and pulled in the longitudinal direction of the central drive shaft 2 by the fluid pressure cylinder device 32 as needed. When the movable arm 32 is pressed with a predetermined force by the fluid pressure cylinder device 32, the positioning ring 26 is pressed against the core adapter group 6 via the spacer 27. Accordingly, the positioning ring 25 and the positioning ring 26 can position the core adapter group at a predetermined position and can apply a predetermined pressing force to the core adapter group 6. Note Depending winding conditions Ru obtained might spacer 27 and spacer 29 is not required.

図1に示すフリクション巻軸1から巻取ロールRを取出すには、中心駆動軸2を巻取ロールRに対して巻取時と反対方向に回転させるか、又は巻取ロールRを中心駆動軸2に対して巻取時と同じ方向に回転させることにより、巻芯アダプター5の環状本体8に対して巻取カラー3を、図3の矢印A1が指す方向の反対方向に回転させて、球体17を細溝16の深い部分に移動させる。その後、中心駆動軸2を右端が自由端となる片持ち支持状態にして、中心駆動軸2の右端から巻取ロールRを巻芯アダプター5と共に抜き取る。この実施例では、巻芯アダプター5を抜き取る前に、スペーサ29、右側の位置決め環26を抜き取る。また流体圧シリンダ装置32により押圧部材30を右方へ後退させておく。巻芯アダプター5を巻取カラー群4から抜き取るとき、環状本体8の内周面に係合する球体17は細溝16に直交する方向にも回転し得るので巻芯アダプター5を抜き取り易い。 In order to take out the winding roll R from the friction winding shaft 1 shown in FIG. 1, the center driving shaft 2 is rotated in the opposite direction to the winding roll R or the winding roll R is moved to the central driving shaft. 2 is rotated in the same direction as during winding, whereby the winding collar 3 is rotated in the opposite direction to the direction indicated by the arrow A1 in FIG. 17 is moved to a deep part of the narrow groove 16 . Thereafter, the center drive shaft 2 is brought into a cantilever support state in which the right end is a free end, and the winding roll R is pulled out together with the core adapter 5 from the right end of the center drive shaft 2. In this embodiment, before the core adapter 5 is extracted, the spacer 29 and the right positioning ring 26 are extracted. Further, the pressing member 30 is moved backward to the right by the fluid pressure cylinder device 32. When the core adapter 5 is extracted from the winding collar group 4, the spherical body 17 that engages with the inner peripheral surface of the annular body 8 can also rotate in the direction perpendicular to the narrow groove 16 , so that the core adapter 5 can be easily extracted.

帯状シートSを巻取るには、予め各帯状シートSを巻取るための巻芯Cを夫々巻芯アダプター5に装着しておき、その巻芯アダプター5を、夫々中心駆動軸2の右端から巻取カラー群4の外周に所要位置まで差し込み、更に右側の位置決め環26、スペーサ29を差し込む。次に中心駆動軸2の右端をスピンドルで支持した状態にする。その後、流体圧シリンダ装置32を作動させて可動腕31を左方へ進出させ、巻取終了までその状態を維持する。それによって、巻芯アダプター群6は、図1に示すように巻取カラー群4上の長手方向の所定位置に拘束されると共に、その長手方向の押圧力を受ける。そして巻芯アダプター群6において隣り合う関係にある巻芯アダプター5の環状本体8同士は夫々ころがり軸受10を挟んで接するので、各巻芯アダプター5は正確に位置決めされ、巻芯アダプター5上の巻芯Cも正確に位置決めされる。 In order to wind the belt-like sheet S, the cores C for winding the belt-like sheets S are respectively attached to the core adapters 5, and the core adapters 5 are wound from the right end of the central drive shaft 2, respectively. Insert the outer periphery of the collar group 4 to the required position, and then insert the right positioning ring 26 and spacer 29 . Next, the right end of the center drive shaft 2 is supported by the spindle. Thereafter, the fluid pressure cylinder device 32 is operated to move the movable arm 31 to the left, and the state is maintained until the winding is completed. Thereby, the core adapter group 6 is restrained at a predetermined position in the longitudinal direction on the winding collar group 4 as shown in FIG. 1 and receives a pressing force in the longitudinal direction. Since the annular main bodies 8 of the core adapters 5 that are adjacent to each other in the core adapter group 6 are in contact with each other with the rolling bearings 10 in between, the core adapters 5 are accurately positioned and the cores on the core adapters 5 are positioned. C is also positioned accurately.

その後、各巻芯Cに帯状シートSの先端を止着してモータMを起動すると、中心駆動軸2は、図3において矢印A1が指す方向に回転し、巻取カラー3には摩擦部材34を介して中心駆動軸2の回転力が伝達される。一方、巻芯Cには帯状シートSの張力に応じた回転抵抗が生じる。そのため、巻芯Cは巻芯アダプター5の環状本体8に対して図3の矢印A1が指す方向の反対方向に回転しようとし、各可動体12は底面傾斜溝11の浅いほうへ移動しようとするので、可動体12による巻芯Cの内周面の押圧力が増大し、巻芯アダプター5による巻芯Cの把持力は増大する。また巻取カラー3は、巻芯アダプター5の環状本体8に対して、中心駆動軸2と同方向に回転しようとするので、球体17が細溝16の浅い方へ移動すると共に、保持環18が巻取カラー3に対して中心駆動軸2の回転方向と反対の方向に回転し、各球体17は夫々の細溝16の底面によって押上げられて等量ずつ同時に突出し、環状本体8の内周面を押圧する。それによって巻取カラー3の把持機構15は巻芯アダプターの環状本体8を巻取カラー3と同心に把持する。したがって、巻芯アダプター5上の巻芯Cの中心軸線と中心駆動軸2の中心軸線と同心になり、その巻芯Cは振れ回りすることなく回転する。 Thereafter, when the leading end of the belt-like sheet S is fixed to each core C and the motor M is started, the center drive shaft 2 rotates in the direction indicated by the arrow A1 in FIG. The rotational force of the center drive shaft 2 is transmitted through the via. On the other hand, a rotational resistance corresponding to the tension of the belt-like sheet S is generated in the core C. Therefore, the core C tries to rotate in the direction opposite to the direction indicated by the arrow A <b> 1 in FIG. 3 with respect to the annular body 8 of the core adapter 5, and each movable body 12 tries to move to the shallower side of the bottom inclined groove 11. Therefore, the pressing force of the inner peripheral surface of the core C by the movable body 12 increases, and the gripping force of the core C by the core adapter 5 increases. Further, the winding collar 3 tends to rotate in the same direction as the central drive shaft 2 with respect to the annular body 8 of the core adapter 5, so that the sphere 17 moves to the shallower side of the narrow groove 16 and the holding ring 18. There is rotated in the direction opposite to the rotating direction of the central drive shaft 2 against the winding collar 3, the spherical bodies 17 are pushed up by the bottom surface of the narrow groove 16 each simultaneously protrude by equal amounts, of the annular body 8 Press the peripheral surface. As a result, the gripping mechanism 15 of the winding collar 3 grips the annular body 8 of the core adapter 5 concentrically with the winding collar 3 . Accordingly, the central axis concentric with the central axis and the central drive shaft 2 of the winding core C on the core adapter 5, rotates without the core C is for whirling.

帯状シートSの巻取中に隣り合う巻取ロールRの巻取半径に差が生じることにより両者の回転数に差が生じ、それによって、巻芯Cを装着した巻芯アダプター5の環状本体8相互間でスリップが生じたとしても、隣り合う関係にある巻芯アダプター5の環状本体8同士は夫々ころがり軸受10を挟んで接するので、環状本体8相互間のスリップによる摩擦損失は比較的小さいものになる。それゆえ、摩擦部材34と巻取カラーとの摩擦力によって中心駆動軸から巻芯Cに伝達される回転力の、摩擦損失による低減は僅かなものになる。この実施例では、巻取カラー3は中心駆動軸に対してころがり軸受3aを介して環状本体8と一体になって回転するので、環状本体8と中心駆動軸との間の摩擦損失も比較的小さいものになるので、回転力の摩擦損失による低減は一層僅かなものになる。 During winding of the belt-like sheet S, a difference in winding radius between adjacent winding rolls R causes a difference in the number of rotations of the two, thereby causing the annular body 8 of the winding core adapter 5 to which the winding core C is attached. Even if slip occurs between each other, the annular main bodies 8 of the core adapters 5 that are adjacent to each other are in contact with each other with the rolling bearing 10 interposed therebetween, so that friction loss due to slip between the annular main bodies 8 is relatively small. become. Therefore, the reduction of the rotational force transmitted from the center drive shaft 2 to the core C by the frictional force between the friction member 34 and the winding collar 3 is small due to friction loss. Since this embodiment, the winding collar 3 is rotating in unison with the annular body 8 via a bearing 3a rolling with respect to the central drive shaft 2, the friction loss between the annular body 8 and the central drive shaft 2 Therefore, the reduction due to the friction loss of the rotational force becomes even smaller.
