Description

本発明は、紙やフィルム等のシート状の部材を巻取る巻取装置に用いる巻取軸及び巻取軸のホルダに用いる係止部材に関する。   The present invention relates to a winding shaft used for a winding device that winds a sheet-like member such as paper or film, and a locking member used for a holder of the winding shaft.

一般に、巻取装置では、原反側から繰り出された紙やプラスチックフィルムまたはアルミ箔等の広幅シートを、長手方向に沿って複数の細幅シートにスリットして、これら細幅シートを巻取軸上に装着した巻芯(紙管)上に巻き取っている。この種の巻取軸は、従来からいろいろな機構、構造のものが提案されているが、シートを巻取る紙管ホルダを構成するため、クランプ機構またはこれに類する機構を備えている。このうち、エアチャック式に紙管を巻取軸と一体に回転させて、この紙管上に細幅シートを巻取るものがある。例えば、図11に示す紙管ホルダ(クランプ機構)10は、外面から出没するように駒状のエアチャック(係止部材)40を備えており、図11の(A)から(B)に示すように、これら係止部材40を放射方向(径方向)に突出させることで、周囲の部材を押し付けられるようにしている(符合D2参照)。図12に示す巻取装置100は、図11に示した紙管ホルダ10をシャフトAの外周に、複数、同軸状にそれぞれ軸方向に対して不動でかつ周方向に回転自在となるように並列せしめて装着している。そして、これら紙管ホルダ10の外周に着脱自在式に被固定部材(紙管)Bを嵌挿装着させて、上述のように係止部材40を放射方向に突出させることで、これら紙管Bを固定して、巻取作業を行えるようにしている。そして、巻取作業が終了すると、係止部材40を没入させて、紙管Bを解放して、巻取られたウエブロール(巻取製品)を紙管Bとともに巻取軸100から取り出せるようにしている。   Generally, in a winding device, a wide sheet such as paper, plastic film, or aluminum foil fed from the original side is slit into a plurality of narrow sheets along the longitudinal direction, and these narrow sheets are wound on a winding shaft. It is wound on a core (paper tube) mounted on top. Various types of mechanisms and structures have been proposed for this type of take-up shaft, but a clamp mechanism or a similar mechanism is provided for constituting a paper tube holder for taking up a sheet. Among these, there is an air chuck type in which a paper tube is rotated integrally with a take-up shaft and a narrow sheet is wound on the paper tube. For example, the paper tube holder (clamp mechanism) 10 shown in FIG. 11 includes a piece-like air chuck (locking member) 40 so as to protrude from the outer surface, and is shown in FIGS. Thus, the surrounding members can be pressed by projecting these locking members 40 in the radial direction (radial direction) (see reference numeral D2). The winding device 100 shown in FIG. 12 is arranged in parallel so that the paper tube holder 10 shown in FIG. At least worn. Then, a fixed member (paper tube) B is detachably attached to the outer periphery of the paper tube holder 10 and the locking member 40 is protruded in the radial direction as described above. Is fixed so that the winding work can be performed. When the winding operation is completed, the locking member 40 is immersed, the paper tube B is released, and the wound web roll (winding product) can be taken out from the winding shaft 100 together with the paper tube B. ing.

巻取軸100とこの巻取機能を担う紙管ホルダ10に要求される性能は、近年より高度なものになっている。例えば、電子部品などに使用されるテープでは、従来のものと比べて、より幅の狭い細幅品が要求されている。このため、例えば、特許文献1に記載のクランプ機構及びこのクランプ機構を利用する巻取軸では、従来のものと比べてより幅の狭い細幅品を巻き取れるようにしている。特に、この紙管ホルダ(クランプ機構)10は、ホルダ20、ベアリング30及び係止部材40から構成されている(図11参照)。このホルダ20は偏平円筒形状で、内部に左右対称の二つのチャンバを形成しており、これらチャンバ内にベアリング30を収容している。また、ホルダ20は、これらベアリング30によって、外部の駆動機構(図示略)によって回転駆動されるシャフトA(図12参照)の外周上に摺動自在に取付けられている。また、ホルダ20は、外表面に開口した係合孔に係止部材40を出没自在に収容している。ホルダ20内では、ベアリング30と係止部材40が直接当接しており、駆動手段によりベアリング30を軸方向にスライドさせると(図11(B)の符合D1a、D1b参照)、係止部材40がベアリング30により押圧されて、係合孔から放射方向に突出している(図11(B)の符合D2参照)。従って、紙管ホルダ10は、ホルダ20を軸支する機能と、係止部材40を押圧する機能の二つを備えるようにベアリング30を含んでおり、構成要素の数を最小にして、作用幅を大幅に狭めることを達成している。   The performance required for the take-up shaft 100 and the paper tube holder 10 responsible for this take-up function has become higher in recent years. For example, a tape used for an electronic component or the like is required to have a narrow product having a narrower width than a conventional tape. For this reason, for example, the clamp mechanism described in Patent Document 1 and the winding shaft that uses this clamp mechanism can take up a narrower product than a conventional one. In particular, the paper tube holder (clamp mechanism) 10 includes a holder 20, a bearing 30, and a locking member 40 (see FIG. 11). The holder 20 has a flat cylindrical shape, and two symmetrical chambers are formed inside, and a bearing 30 is accommodated in these chambers. Further, the holder 20 is slidably mounted on the outer periphery of the shaft A (see FIG. 12) rotated by an external drive mechanism (not shown) by these bearings 30. Moreover, the holder 20 accommodates the locking member 40 in an engagement hole opened on the outer surface so as to be able to appear and retract. In the holder 20, the bearing 30 and the locking member 40 are in direct contact with each other, and when the bearing 30 is slid in the axial direction by the driving means (see symbols D1a and D1b in FIG. 11B), the locking member 40 is It is pressed by the bearing 30 and protrudes radially from the engagement hole (see reference numeral D2 in FIG. 11B). Therefore, the paper tube holder 10 includes the bearing 30 so as to have two functions of supporting the holder 20 and pressing the locking member 40, minimizing the number of components and reducing the working width. Has achieved a significant narrowing.

特許文献1に開示された紙管ホルダ10は、狭い幅の紙管Bを保持させるのに効果的である。しかしながら、この構成では、様々な幅の紙管Bを保持させるのに課題が残されていた。即ち、一般に、巻取装置では、スリット後の細幅シートの端部同士が重ならないように、細幅シートを二つ又は複数個の巻取軸100上に千鳥状に振り分けて、ロール状に巻取っている。このため、巻取軸100のシャフトA上に並置される各紙管ホルダ10の間隔、つまり各係止部材40の巻取りピッチPOは一定である。そして、図12に示すように、この巻取りピッチPOに合わせて、各紙管ホルダ10上に所定のピッチP1で紙管Bを並列配置させている。しかしながら、図13に示すように、紙管ホルダのピッチPOと異なるピッチP2、例えばより大きなピッチP2で、紙管ホルダ10上に複数個の紙管Bを並列配置させる場合には、各係止部材40に対して割り当てられる紙管Bに位置ずれが生じることになる。特に、細幅シートを巻取る場合において、紙管ホルダ10のピッチPOと、紙管BのピッチP2が異なる結果、一つの係止部材40に対して二つの紙管Bが割り当てられるような時には、係止部材40に加わる張力が増大するため、係止部材40の操作性を低下させるおそれがあった。このような問題は、上記特許文献1に記載の紙管ホルダ10に限らず、広く一般に課題とされている。このため、従来の巻取軸100では、特定の紙管ホルダ10により、巻き取れる紙管Bの幅が限定されていた。
特許第3632175号公報
The paper tube holder 10 disclosed in Patent Document 1 is effective for holding a paper tube B having a narrow width. However, in this configuration, a problem remains in holding the paper tubes B having various widths. That is, in general, in a winding device, narrow sheets are distributed in a zigzag pattern on two or a plurality of winding shafts 100 so that the ends of the narrow sheets after slitting do not overlap each other, and are rolled. Winding up. Therefore, the interval between the paper tube holders 10 juxtaposed on the shaft A of the winding shaft 100, that is, the winding pitch P O of each locking member 40 is constant. Then, as shown in FIG. 12, in accordance with the the winding pitch P O, and is arranged in parallel paper tube B at a predetermined pitch P 1 on each paper tube holder 10. However, as shown in FIG. 13, the pitch P 2 which is different from the pitch P O of paper tube holder, for example a larger pitch P 2, the case of parallel arrangement of a plurality of paper tube B on paper tube holder 10, A misalignment occurs in the paper tube B assigned to each locking member 40. In particular, when winding a narrow sheet, the pitch P O of the paper tube holder 10 and the pitch P 2 of the paper tube B are different, so that two paper tubes B are allocated to one locking member 40. In some cases, since the tension applied to the locking member 40 increases, the operability of the locking member 40 may be reduced. Such a problem is not limited to the paper tube holder 10 described in Patent Document 1 and is generally regarded as a problem. For this reason, in the conventional winding shaft 100, the width of the paper tube B that can be wound is limited by the specific paper tube holder 10.

以下、本発明に係る好適な実施形態について、添付した図を参照して説明する。
背景技術で説明したように、一般に、巻取装置100のシャフトAの外周には複数個のクランプ機構(紙管ホルダ)10が同軸状に並置されており、これら紙管ホルダ10の外面上には、出没自在なように係止部材40が備えられている(図12参照)。そして、紙管ホルダ10の外面から係止部材40を突出させることで、周囲の紙管Bを保持させている(図11参照)。通常、係止部材40の突出高さは一様に定められている。これに対して、本発明では、同様に巻取装置100のシャフトAの外周に複数個の紙管ホルダ10を同軸状に並置させて、これら紙管ホルダ10の外面上に、出没自在なように係止部材40を備えるが、係止部材40の突出高さをより細かく調整させる。そして、紙管ホルダPOと紙管のピッチP2が異なる結果、紙管ホルダ10上に紙管Bがずれて配置されるような場合であっても(図13参照)、特定の係止部材40の突出高さを調整することで、位置ずれに合わせて、柔軟に巻取操作が行えるようする。本発明に係る係止部材40の突出高さの調整は、様々な紙管ホルダ10に適用することができるが、以下の説明では、紙管ホルダ10は、基本的には、特許文献1に開示されたように構成されるものとする。尚、特許文献1の発明は、本発明と同一出願人によって出願されており、この内容は参照上、本発明に包含される。
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
As described in the background art, in general, a plurality of clamp mechanisms (paper tube holders) 10 are coaxially arranged on the outer periphery of the shaft A of the winding device 100, and on the outer surface of these paper tube holders 10. Is provided with a locking member 40 so that it can be moved in and out (see FIG. 12). And the surrounding paper tube B is hold | maintained by making the latching member 40 protrude from the outer surface of the paper tube holder 10 (refer FIG. 11). Usually, the protrusion height of the locking member 40 is determined uniformly. On the other hand, in the present invention, similarly, a plurality of paper tube holders 10 are coaxially juxtaposed on the outer periphery of the shaft A of the winding device 100 so that the paper tube holders 10 can be projected and retracted on the outer surface. Is provided with the locking member 40, but the protruding height of the locking member 40 is adjusted more finely. Even when the paper tube B is shifted on the paper tube holder 10 as a result of the difference between the paper tube holder PO and the paper tube pitch P 2 (see FIG. 13), a specific locking By adjusting the protruding height of the member 40, the winding operation can be performed flexibly in accordance with the positional deviation. The adjustment of the protruding height of the locking member 40 according to the present invention can be applied to various paper tube holders 10, but in the following description, the paper tube holder 10 is basically disclosed in Patent Document 1. It shall be configured as disclosed. The invention of Patent Document 1 is filed by the same applicant as the present invention, and the contents thereof are included in the present invention for reference.

図1には、本発明に係る紙管ホルダ10が示されている。但し、図1では、説明を容易にするため、図11に示した紙管ホルダ10、10を二つ、並置して示している。また、図1では、図13に示したように、紙管ホルダ10と紙管BのピッチPO、P2が異なるため、二つの紙管ホルダ10、10にまたがるように、一つの紙管Bがずれて配置される場合を示している。このような場合、従来技術では、図11の(A)、(B)に示したように、これら二つの紙管ホルダ10、10を作用させると、夫々、符合D2で示したように、係止部材40を一様な高さで放射方向に突出させて、双方から紙管Bの内面を押圧させていた。これに対して、本発明に係る実施形態では、図1の(A)、(B)に示すように、これら二つの紙管ホルダ10、10を作用させても、夫々、符合D2、D2’で示すように、係止部材40の突出高さを異なるように調整させている。例えば、一方(図1の右側)の紙管ホルダ10は、図11に示したように通常通りに作用して、符合D2で示すように、放射方向に突出する係止部材40により紙管Bを保持させるが、他方(図1の左側)の紙管ホルダ10は、符合D2’で示すように、係止部材40の突出高さを部分的に調整させて、紙管Bが圧接される範囲を限定させている。つまり、左側の紙管ホルダ10では、符合Sで示すように、係止部材40を突出させても、この上方の紙管Bを押圧しないように、係止部材40の突出高さを部分的に低くしている。この結果、二つの紙管ホルダ10、10上にまたがるように配置された紙管Bは、一方(図1の右側)の紙管ホルダ10のみから押圧されて、他方(図1の左側)の紙管ホルダ10からは押圧されない。従って、紙管ホルダ10と紙管Bとの間に位置ずれが生じていても、この位置ずれに対応して、柔軟に紙管Bを保持することができる。 FIG. 1 shows a paper tube holder 10 according to the present invention. However, in FIG. 1, two paper tube holders 10 and 10 shown in FIG. In FIG. 1, as shown in FIG. 13, since the pitches P O and P 2 of the paper tube holder 10 and the paper tube B are different, one paper tube extends over the two paper tube holders 10 and 10. The case where B is shifted and shown is shown. In such a case, in the prior art, when these two paper tube holders 10 and 10 are acted as shown in FIGS. The stop member 40 was protruded in the radial direction at a uniform height, and the inner surface of the paper tube B was pressed from both sides. On the other hand, in the embodiment according to the present invention, as shown in FIGS. 1A and 1B, even if these two paper tube holders 10 and 10 are operated, the signs D2 and D2 ′ are respectively obtained. As shown, the protrusion height of the locking member 40 is adjusted to be different. For example, the paper tube holder 10 on one side (right side in FIG. 1) operates normally as shown in FIG. 11, and as shown by reference numeral D2, the paper tube holder 10 protrudes radially by the locking member 40. However, the paper tube holder 10 on the other side (left side in FIG. 1) is press-contacted with the paper tube B by partially adjusting the protruding height of the locking member 40 as indicated by reference numeral D2 ′. The range is limited. That is, in the paper tube holder 10 on the left side, as indicated by the symbol S, the protruding height of the locking member 40 is partially set so that even if the locking member 40 is protruded, the upper paper tube B is not pressed. Is low. As a result, the paper tube B arranged so as to straddle the two paper tube holders 10 and 10 is pressed only from one (right side in FIG. 1) and from the other (left side in FIG. 1). It is not pressed from the paper tube holder 10. Therefore, even if a positional deviation occurs between the paper tube holder 10 and the paper tube B, the paper tube B can be held flexibly in response to the positional deviation.

ここで、紙管ホルダ10の操作について説明する。
例示した紙管ホルダ10は、ホルダ20内にベアリング30と係止部材40を直接当接させるように収容しており、図11に示したように、ベアリング30をスライド移動させると(図11(B)の符合D1a、D1b参照)、係止部材40がベアリング30によって押圧されて、放射方向に突出している(図11(B)の符合D2参照)。この構成は、図2と3に示すように、主にベアリング30の収容状態によって、第一の形態と第二の形態に分けることができる。
即ち、第一の形態では、図2の(A)に示すように、紙管ホルダ10は、係止部材40の両側にベアリング30を夫々回転自在かつ軸方向にスライド自在に設けている。そして、図2の(B)に示すように、これらベアリング30の各々を係止部材40に対して同時に軸方向にスライドさせることにより、係止部材40を傾斜状外周面33、43に沿って係合孔から放射方向に突出させている。尚、図2に示した例では、並置された4つのベアリングの夫々が、係止部材40に向ってスライドしている。
また、第二の形態では、図3の(A)に示すように、紙管ホルダ10は、係止部材40の両側にベアリング30を設けるが、これらベアリング30のうち、一方のベアリング30aを回転自在かつ軸方向不動に固定させており、他方のベアリング30bのみを回転自在かつ軸方向にスライド自在に設けている。そして、この軸方向に移動可能なベアリング30bのみを係止部材40に対して軸方向にスライドさせることにより、係止部材40を傾斜状外周面33、43に沿って係合孔から放射方向に突出させている。尚、図3に示した例では、並置された4つのベアリングのうち、中央の二つのベアリング30bだけが、夫々係止部材40に向って移動している。
即ち、第二の形態(図3参照)では、第一の形態(図2参照)と異なり、二つのベアリングのうちの一方30aを止め輪(スナップリング)39により軸方向の移動を固定させている。好適には、この固定手段は止め輪39であるが、他、シャフトAに固定したリングにビスを係止させて、同様の効果を奏してもよい。このため、第二の形態(図3参照)では、ベアリング30をスライド移動させる手段の数は第一の形態(図2参照)と比較して約半数でよい。また、この構成では、端部の紙管ホルダ10を位置決めする定置リング15が不要になるという効果を奏する。
このように、紙管ホルダ10は主に二つの形態に分けることができるが、本発明では、いずれの形態も利用することができる。
Here, the operation of the paper tube holder 10 will be described.
The illustrated paper tube holder 10 is accommodated in the holder 20 so that the bearing 30 and the locking member 40 are in direct contact with each other, and when the bearing 30 is slid as shown in FIG. B), reference numerals D1a and D1b), and the locking member 40 is pressed by the bearing 30 and protrudes in the radial direction (see reference numeral D2 in FIG. 11B). As shown in FIGS. 2 and 3, this configuration can be divided into a first form and a second form mainly depending on the accommodation state of the bearing 30.
That is, in the first embodiment, as shown in FIG. 2A, the paper tube holder 10 is provided with bearings 30 on both sides of the locking member 40 so as to be rotatable and slidable in the axial direction. Then, as shown in FIG. 2B, each of the bearings 30 is simultaneously slid with respect to the locking member 40 in the axial direction, so that the locking member 40 is moved along the inclined outer peripheral surfaces 33 and 43. It protrudes in the radial direction from the engagement hole. In the example shown in FIG. 2, each of the four bearings juxtaposed slides toward the locking member 40.
In the second embodiment, as shown in FIG. 3A, the paper tube holder 10 is provided with bearings 30 on both sides of the locking member 40. Of these bearings 30, one of the bearings 30a is rotated. It is freely fixed and fixed in the axial direction, and only the other bearing 30b is provided rotatably and slidable in the axial direction. Then, only the bearing 30b movable in the axial direction is slid in the axial direction with respect to the locking member 40, so that the locking member 40 is moved radially from the engagement hole along the inclined outer peripheral surfaces 33 and 43. It is protruding. In the example shown in FIG. 3, of the four bearings arranged side by side, only the two central bearings 30 b move toward the locking member 40.
That is, in the second form (see FIG. 3), unlike the first form (see FIG. 2), one of the two bearings 30a is fixed to the axial movement by a snap ring 39. Yes. Preferably, the fixing means is a retaining ring 39, but a similar effect may be achieved by locking a screw to a ring fixed to the shaft A. For this reason, in the second embodiment (see FIG. 3), the number of means for slidingly moving the bearing 30 may be about half that in the first embodiment (see FIG. 2). In addition, this configuration has an effect that the stationary ring 15 for positioning the paper tube holder 10 at the end is not necessary.
As described above, the paper tube holder 10 can be mainly divided into two forms, but any form can be used in the present invention.

ここで、紙管ホルダ10に用いられるホルダについて説明する。
図5には、図1〜3に示したホルダ20の(A)正面図と(B)該正面図のb−b線に沿った断面図が例示されている。図示されるように、ホルダ20は偏平円筒状に形成され、内壁23中央から本体中心に向けて突条部24を突出形成して中空室(空隙部)27(図5の(A)参照)を左右対称の二つのチャンバ(室)27a、27b(図5の(B)参照)に分けている。各々のチャンバ27a、27bには、ベアリング30、30(図1〜3参照)が収納される。さらに、突条部24の側面に停止面25を形成して、軸方向にスライドするベアリング30に対して停止機能を備えている。この際、停止面25を突条部24より若干手前に形成して、スライドするベアリング30が直接突条部24に当接することを防止させてもよい。またホルダ20は外表面21上に少なくとも二個以上の係合孔26を放射方向に適宜間隔を置いて形成して、この係合孔26に係止部材40(図1〜3参照)を放射方向に出没自在に備える。係止部材40は係合孔26から突出することで、隣接する紙管Bの内面を押圧する。図示したホルダ20は、合計4個の係合孔26を約90°の等間隔で設けており、これら係合孔26内に係止部材40を配置できるようにしている。しかしながら、係合孔26の個数は4個に限定されず、少なくとも2個以上であればよい。
Here, the holder used for the paper tube holder 10 will be described.
FIG. 5 illustrates (A) a front view of the holder 20 shown in FIGS. 1 to 3 and (B) a cross-sectional view taken along the line bb of the front view. As shown in the figure, the holder 20 is formed in a flat cylindrical shape, and a protruding portion 24 is formed to project from the center of the inner wall 23 toward the center of the main body to form a hollow chamber (gap portion) 27 (see FIG. 5A). Is divided into two symmetrical chambers 27a and 27b (see FIG. 5B). Bearings 30 and 30 (see FIGS. 1 to 3) are accommodated in the respective chambers 27a and 27b. Furthermore, the stop surface 25 is formed in the side surface of the protrusion part 24, and the stop function is provided with respect to the bearing 30 which slides to an axial direction. At this time, the stop surface 25 may be formed slightly before the ridge 24 to prevent the sliding bearing 30 from directly contacting the ridge 24. Further, the holder 20 has at least two engagement holes 26 formed on the outer surface 21 at appropriate intervals in the radial direction, and a locking member 40 (see FIGS. 1 to 3) is radiated to the engagement holes 26. Prepare to move freely in the direction. The locking member 40 protrudes from the engagement hole 26 and presses the inner surface of the adjacent paper tube B. The illustrated holder 20 is provided with a total of four engagement holes 26 at equal intervals of about 90 ° so that the locking members 40 can be arranged in these engagement holes 26. However, the number of the engagement holes 26 is not limited to four and may be at least two.

次に、ベアリング30について説明する。
図1、11から理解できるように、ベアリング30はホルダ20のチャンバ27の水平内壁部23(図5参照)とスライド自在に密着するように外輪31を定めるとともに、シャフトA(図12参照)に対して周方向に回転自在に密着するように内輪32を定めており、ホルダ20により回転自在に嵌合される。ただし、図2に示した第一の形態に係る一組のベアリング30は、いずれも軸方向にスライド自在に配置されるが、図3に示した第二の形態に係る一組のベアリング30は、一方は軸方向にスライド自在に配置され、他方は軸方向に固定されるという相違がある。この軸方向に固定されるベアリング30aは、好適にはベアリング固定用の止め輪39を備える(図3参照)。これら図では、ベアリング30としてボールベアリングを示しているが、これは、紙管ホルダ10は主に放射方向に力を受けるためである。しかしながら、実施の形態によってはボールベアリング以外の種類のベアリング30を使用することは可能であって、またベアリング30の具体的な種類によって本発明は限定されないことを理解されたい。
Next, the bearing 30 will be described.
As can be understood from FIGS. 1 and 11, the bearing 30 defines an outer ring 31 so as to be slidably in close contact with the horizontal inner wall portion 23 (see FIG. 5) of the chamber 27 of the holder 20 and is attached to the shaft A (see FIG. 12). On the other hand, the inner ring 32 is defined so as to be in close contact with the circumferential direction so as to be freely rotatable, and is rotatably fitted by the holder 20. However, although the set of bearings 30 according to the first embodiment shown in FIG. 2 are all slidably arranged in the axial direction, the set of bearings 30 according to the second embodiment shown in FIG. There is a difference that one is slidably arranged in the axial direction and the other is fixed in the axial direction. The bearing 30a fixed in the axial direction preferably includes a retaining ring 39 for fixing the bearing (see FIG. 3). In these drawings, a ball bearing is shown as the bearing 30. This is because the paper tube holder 10 receives a force mainly in the radial direction. However, it should be understood that some types of bearings 30 other than ball bearings may be used in some embodiments, and that the invention is not limited by the specific type of bearing 30.

この紙管ホルダ10では、ベアリング30は、ホルダ20内で、係止部材40と直接当接するように収容される(図2(A)、図3(A)参照)。好ましくは、ベアリング30と係止部材40の双方の端部に傾斜状外周面33、43を備えて、これら傾斜状外周面33、43によりベアリング30と係止部材40を直接当接させて、図2(B)又は図3(B)に示したように、ベアリング30のスライド運動を係止部材40の突出運動に滑らかに伝えるようにする。但し、この傾斜状外周面33、43は曲面状の外周面でもよく、または平面状の外周面でもよく、また、これら傾斜状外周面33、43の大きさは任意である。また、市販のベアリング30はこの軸受外径面と側面との交わる位置で角を取り除くように面取り(丸み)を形成している場合があるため、この部位をベアリング30の傾斜状外周面33として直接利用してもよい。   In the paper tube holder 10, the bearing 30 is accommodated in the holder 20 so as to directly contact the locking member 40 (see FIGS. 2A and 3A). Preferably, both end portions of the bearing 30 and the locking member 40 are provided with inclined outer peripheral surfaces 33 and 43, and the bearing 30 and the locking member 40 are directly brought into contact with each other by the inclined outer peripheral surfaces 33 and 43, As shown in FIG. 2B or FIG. 3B, the sliding motion of the bearing 30 is smoothly transmitted to the protruding motion of the locking member 40. However, the inclined outer peripheral surfaces 33 and 43 may be curved outer peripheral surfaces or flat outer peripheral surfaces, and the sizes of the inclined outer peripheral surfaces 33 and 43 are arbitrary. Further, since the commercially available bearing 30 may be chamfered (rounded) so as to remove a corner at a position where the outer diameter surface and the side surface of the bearing intersect, this portion is used as the inclined outer peripheral surface 33 of the bearing 30. You may use it directly.

次に、ベアリング30をスライドさせる駆動手段について説明する。
ベアリング30は、駆動手段によって押圧されることでスライドする。この駆動手段は任意に構成することができるが、好適には流体圧力(例えば、圧搾空気)により作用する。例えば、図6に示すように、ベアリング30に対して近接配置されるように、駆動手段としてピストン50を設けて、このピストン50に対して、図12に示したようなシャフト内の送気路9a、9b又は9cから流体圧力を伝える。そして、ピストン50を移動させることで、ベアリング30を押圧させて、図2(B)又は図3(B)に示したように、軸方向にスライド移動させる。このピストン50は、シャフトAの軸方向に対して垂直に移動して、主にベアリング30の内輪を押圧させることで、ベアリング30を軸方向にスライドさせている。ただし、送気路9a、9b又は9cの数と構成は、図12に示したものに限定される必要はない。また、ベアリング30を軸方向にスライド移動させるピストン50は、他、様々に構成することができる。例えば、このピストンは、図7に示すように、リング状のピストン60であって、送気路9a、9b又は9cから圧搾空気が供給されると、シャフトAの軸方向に対して平行に移動して、主にベアリング30の内輪及び外輪の双方を押圧させることで、ベアリング30を軸方向にスライドさせてもよい。また、図12から理解できるように、シャフトA内に圧搾空気を供給するため、シャフトAの端部側にロータリージョイント部70を隣接配置して、この外表面上に形成した送気孔19a、19b、19cから、外部から取り込んだ空気を送気路9a、9b、9cにそれぞれ送るようにしてもよい。本発明を実施する上で、ベアリング30をスライドさせる駆動手段50、60の詳細は重要ではないため、さらなる説明は省略するが、具体例として、本発明に包含される特許文献1に記載のように構成することができる。
Next, driving means for sliding the bearing 30 will be described.
The bearing 30 slides when pressed by the driving means. The drive means can be arbitrarily configured, but preferably acts by fluid pressure (eg, compressed air). For example, as shown in FIG. 6, a piston 50 is provided as a driving means so as to be disposed close to the bearing 30, and the air supply path in the shaft as shown in FIG. The fluid pressure is transmitted from 9a, 9b or 9c. Then, by moving the piston 50, the bearing 30 is pressed and slid in the axial direction as shown in FIG. 2B or FIG. 3B. The piston 50 moves perpendicularly to the axial direction of the shaft A and mainly presses the inner ring of the bearing 30 to slide the bearing 30 in the axial direction. However, the number and configuration of the air supply passages 9a, 9b, or 9c need not be limited to those shown in FIG. The piston 50 that slides the bearing 30 in the axial direction can be variously configured. For example, as shown in FIG. 7, this piston is a ring-shaped piston 60 that moves in parallel with the axial direction of the shaft A when compressed air is supplied from the air supply passage 9 a, 9 b, or 9 c. Then, the bearing 30 may be slid in the axial direction mainly by pressing both the inner ring and the outer ring of the bearing 30. Further, as can be understood from FIG. 12, in order to supply compressed air into the shaft A, the rotary joint portion 70 is disposed adjacent to the end portion side of the shaft A, and the air supply holes 19a and 19b formed on the outer surface. 19c, the air taken in from the outside may be sent to the air supply passages 9a, 9b, 9c, respectively. The details of the driving means 50 and 60 for sliding the bearing 30 are not important in practicing the present invention, so further explanation is omitted, but as a specific example, as described in Patent Document 1 included in the present invention. Can be configured.

次に、本発明に係る係止部材40について説明する。
以上のように、紙管ホルダ10を構成することで、係止部材40の出没操作が行われるが、これらは従来技術において公知である。本発明では、さらに、予め係止部材40の外面(係止面)41に部分的に高低差Sを設けることで、上述のようにベアリング30をスライドさせて、係止部材40を一様に放射方向に突出させても、特定の係止部材40の突出高さを部分的に低くしている。再度図1を参照すると、左右の二つの紙管ホルダ10は、図2又は3に示したように、夫々等しくベアリング30を駆動させている。しかしながら、左右の二つの紙管ホルダ10は、係止部材40の係止面41の高さを相違させているため、一様に係止部材40を突出させても、夫々異なるクランプ作用を提供している。この結果、図1の右側の紙管ホルダ10は、係止部材40によって、従来と同様に紙管Bを保持させるが、図1の左側の紙管ホルダ10は、高低差Sを有する係止面41を備えた係止部材40によって、限られた領域から紙管ホルダBを保持できるようにしている。このため、二つの紙管ホルダ10にまたがって配置された紙管Bに対して、二つの紙管ホルダ10を作用させても、一方の紙管ホルダ10のみから紙管Bを保持することが可能になる。
Next, the locking member 40 according to the present invention will be described.
As described above, the paper tube holder 10 is configured to allow the locking member 40 to appear and retract, which are well known in the prior art. In the present invention, the height difference S is partially provided on the outer surface (locking surface) 41 of the locking member 40 in advance, so that the bearing 30 is slid as described above, so that the locking member 40 is made uniform. Even when protruding in the radial direction, the protruding height of the specific locking member 40 is partially reduced. Referring again to FIG. 1, the two left and right paper tube holders 10 drive the bearings 30 equally as shown in FIG. 2 or 3. However, since the two left and right paper tube holders 10 have different heights of the locking surface 41 of the locking member 40, even if the locking member 40 protrudes uniformly, a different clamping action is provided. is doing. As a result, the paper tube holder 10 on the right side of FIG. 1 holds the paper tube B by the locking member 40 as in the conventional case, but the paper tube holder 10 on the left side of FIG. The paper tube holder B can be held from a limited area by the locking member 40 having the surface 41. For this reason, even if the two paper tube holders 10 are applied to the paper tube B arranged across the two paper tube holders 10, the paper tube B can be held from only one of the paper tube holders 10. It becomes possible.

係止部材40の突出高さを部分的に低くすることは、様々に構成することができる。例えば、図1〜3に例示した実施形態では、左側の紙管ホルダ10の係止部材40は、係止面41の略半分の高さを低めており、この低められた側Sを突出させても、紙管Bの内面との間にギャップが設けられるようにしている。この範囲は様々に定めることができ、図1〜3に示したように、係止部材40の右側に限り突出高さを低めてもよく、又は、左側に限り突出高さを低めてもよい。但し、係止部材40はホルダ20に対して着脱自在に設けられており、この左右の向きを180°変えることで、一つの係止部材40により、状況に応じて、右又は左側の突出高さを低めることができる。   The protrusion height of the locking member 40 can be variously configured to be partially reduced. For example, in the embodiment illustrated in FIGS. 1 to 3, the locking member 40 of the left paper tube holder 10 has a height that is substantially half of the locking surface 41, and the lowered side S protrudes. However, a gap is provided between the inner surface of the paper tube B. This range can be determined variously, and as shown in FIGS. 1 to 3, the protruding height may be lowered only on the right side of the locking member 40, or the protruding height may be lowered only on the left side. . However, the locking member 40 is provided so as to be detachable with respect to the holder 20, and by changing the right and left direction by 180 °, the right or left protruding height is changed by one locking member 40 depending on the situation. Can be reduced.

このように、図1〜3に示した実施形態では、ベアリング30を一様に駆動させても、特定の係止部材40の突出高さを低くできるようにしている。この際、いずれの係止部材40もベアリングの作用により突出している。しかしながら、実施形態によっては、ベアリング30を一様に駆動させても、特定の係止部材40を突出させないようにすることが好ましい場合がある。例えば、紙管ホルダ10と紙管BのピッチPO、P2が相違する結果、紙管ホルダ10上で紙管Bがずれて配置されるため、3つの紙管ホルダ10上に一つの紙管Bが割り当てられるような場合には、これら紙管ホルダ10のうち一つの作用を停止させることが好ましいことがある。このため、本発明では、さらに、ベアリング30を一様に駆動させても、特定の係止部材40の突出を任意に停止させるようにする。 As described above, in the embodiment shown in FIGS. 1 to 3, even if the bearing 30 is driven uniformly, the protruding height of the specific locking member 40 can be lowered. At this time, any of the locking members 40 protrudes due to the action of the bearing. However, in some embodiments, it may be preferable to prevent the specific locking member 40 from protruding even when the bearing 30 is driven uniformly. For example, as a result of the difference in the pitches P O and P 2 between the paper tube holder 10 and the paper tube B, the paper tube B is shifted on the paper tube holder 10, so that one paper is placed on the three paper tube holders 10. When tube B is assigned, it may be preferable to stop the action of one of these paper tube holders 10. For this reason, in the present invention, even if the bearing 30 is driven uniformly, the protrusion of the specific locking member 40 is arbitrarily stopped.

具体的には、図1〜3に示した実施形態では、係止部材40は下方に備えた傾斜状外周面43によりベアリング30の外輪31と直接当接しており、ベアリング30の軸方向のスライドによって、係止部材40は傾斜状外周面43に沿って放射方向に突出している。これに対して、図4に示した実施形態では、符合Tに示すように、係止部材40は部分的に傾斜状外周面43を備えることで、ベアリング30の外輪31と当接する範囲を限定させている。即ち、図4の右側に示す係止部材40は、図1〜3に示したものと同様に、ベアリング30と当接する傾斜状外周面43を一様に有しており、図3に示したようにベアリング30をスライドさせると、係止部材40はベアリング30から作用を受けて、傾斜状外周面43に沿って放射方向に突出する。しかし、図4の左側に示す係止部材40は、符合Tに示すように、特定の範囲内で傾斜状外周面43を取り除いており、傾斜状外周面43を備えない右側からベアリング30をスライドさせても、ベアリング30と係止部材40の間にギャップがあるので、係止部材40はベアリング30から作用を受けず、係止部材40はホルダ20内に収容されたままになる。尚、図3に示したものと、図4に示したものでは、いずれもベアリング30の駆動は全く同じように行われている。しかし、係止部材40の下方の形状の相違によって、図3に示した例では、左右の係止部材40はともにホルダ20から突出するが、図4に示した例では、左右の係止部材40のうち、右側の係止部材40だけがホルダ20から突出して、左側の係止部材40は、ベアリング30の移動にかかわらず、ホルダ20内に収容されたままになるという変化が生じている。   Specifically, in the embodiment shown in FIGS. 1 to 3, the locking member 40 is in direct contact with the outer ring 31 of the bearing 30 by the inclined outer peripheral surface 43 provided below, and the axial sliding of the bearing 30 is performed. Thus, the locking member 40 protrudes in the radial direction along the inclined outer peripheral surface 43. On the other hand, in the embodiment shown in FIG. 4, as indicated by the symbol T, the locking member 40 is partially provided with an inclined outer peripheral surface 43, thereby limiting the range in contact with the outer ring 31 of the bearing 30. I am letting. That is, the locking member 40 shown on the right side of FIG. 4 has an inclined outer peripheral surface 43 that is in contact with the bearing 30 similarly to those shown in FIGS. When the bearing 30 is slid in this manner, the locking member 40 receives an action from the bearing 30 and protrudes in the radial direction along the inclined outer peripheral surface 43. However, the locking member 40 shown on the left side of FIG. 4 has the inclined outer peripheral surface 43 removed within a specific range, as indicated by the symbol T, and the bearing 30 is slid from the right side without the inclined outer peripheral surface 43. Even if it does, since there is a gap between the bearing 30 and the locking member 40, the locking member 40 is not affected by the bearing 30, and the locking member 40 remains accommodated in the holder 20. 3 and FIG. 4 both drive the bearing 30 in exactly the same way. However, due to the difference in shape below the locking member 40, the left and right locking members 40 both protrude from the holder 20 in the example shown in FIG. 3, but in the example shown in FIG. 40, only the right locking member 40 protrudes from the holder 20, and the left locking member 40 remains accommodated in the holder 20 regardless of the movement of the bearing 30. .

このように、図1〜3に示した実施形態では、係止部材40は、上方の係止面41の形状を変化させることにより、ベアリング30を一様に駆動させても、特定の係止部材40の突出高さを低くできるようにしている。また、図4に示した実施形態では、係止部材40は、下方の傾斜状外周面43の形状を変化させることにより、ベアリングを一様に駆動させても、特定の係止部材40を突出させないようにしている。図1〜3に示した係止部材40の形状と、図4に示した係止部材40の形状は、組み合わせることができる。そして、これら異なる種類の係止部材40は、任意の組合せで紙管ホルダ10に取付けられて、個々の紙管ホルダ10が夫々異なるクランプ作用を提供できるようにする。このため、図13に示したように、紙管ホルダ10と紙管BとのピッチPO、P2が相違する結果、紙管ホルダ10上に紙管Bがずれて配置された場合でも、個々の紙管ホルダ10の作用幅を細かく調整することで、夫々位置ずれに対応して、柔軟に巻取操作を行えるようにする。係止部材40は手動により、任意の組合せで紙管ホルダ10上に取付けられる。そして、ベアリング30を一様に作用させても、個々の紙管ホルダ30が異なる作用幅でクランプ作用を提供できるようにする。この構成では、個別に紙管ホルダ10のクランプ作用の調整を行うにあたり、さらなる制御器やセンサ、また制御手段等を必要とせず、さらに巻取軸100の構成を複雑化させることがないという大きな利点がある。また、係止部材40の形状だけを変更させるので、特に上記特許文献1に記載のように構成された紙管ホルダ10に限らず、同様の係止部材40を利用する様々な紙管ホルダに広く適用することができる。従って、従来の設備投資を利用できるので、コスト面でも大きな利点がある。 As described above, in the embodiment shown in FIGS. 1 to 3, the locking member 40 can change the shape of the upper locking surface 41 so that the bearing 30 can be driven uniformly, even if the bearing 30 is driven uniformly. The protrusion height of the member 40 can be lowered. In the embodiment shown in FIG. 4, the locking member 40 projects a specific locking member 40 even when the bearing is driven uniformly by changing the shape of the lower inclined outer peripheral surface 43. I try not to let you. The shape of the locking member 40 shown in FIGS. 1 to 3 and the shape of the locking member 40 shown in FIG. 4 can be combined. These different types of locking members 40 are attached to the paper tube holder 10 in any combination so that the individual paper tube holders 10 can provide different clamping actions. For this reason, as shown in FIG. 13, even when the paper tube B is displaced on the paper tube holder 10 as a result of the difference in pitch P O and P 2 between the paper tube holder 10 and the paper tube B, By finely adjusting the action width of each paper tube holder 10, it is possible to flexibly perform a winding operation corresponding to each positional shift. The locking member 40 is manually mounted on the paper tube holder 10 in any combination. And even if the bearing 30 is made to act uniformly, the individual paper tube holders 30 can provide the clamping action with different working widths. In this configuration, when adjusting the clamping action of the paper tube holder 10 individually, no additional controller, sensor, control means, or the like is required, and the configuration of the winding shaft 100 is not complicated. There are advantages. Moreover, since only the shape of the locking member 40 is changed, not only the paper tube holder 10 configured as described in Patent Document 1 above, but also various paper tube holders using the same locking member 40. Can be widely applied. Therefore, since the conventional capital investment can be utilized, there is a great advantage in terms of cost.

ここで、係止部材40の外部形状についてより詳しく説明する。
図8には、特に、図1〜3に示した特徴と図4に示した特徴を組み合わせた形状を有する係止部材40について、(A)上方からの斜視図、(B)下方からの斜視図、(C)平面図及び(D)底面図を夫々示している。また、図8の(A)のm−m線に沿った断面図とn−n線に沿った断面図を夫々、図9の(A)と(B)に示している。これら図から理解できるように、基本的に、係止部材40は、ホルダ20の係合孔26から突出できるように、短棒状に形成されている。好適には、係止部材40は駒形状に形成される。
また、好適には、図8の(A)に示すように、紙管B(図1参照)を直接押圧する係止部材40の係止面41をホルダ20の外表面21(図5参照)に沿って湾曲するように形成する。この際、係止部材40をホルダ20の外表面21に没入させるときに、係止面41がホルダ20の外表面21と整列(図1参照)するように係止面41を形成してもよく、または係止面41が幾分外表面21の内側に没入するように係止面41を形成してもよい。後者では、係止面41を外表面21より突出させず操作上摩擦が少ないという利点がある。さらに、図1〜3を参照して説明したように、係止面41の高さは様々に変えることができる。例えば、図8の(A)の符合Sから理解できるように、切削加工により、係止面41の一部を取り除くことで、係止面41の高さを部分的に低くさせてもよい。
また、好適には、係止面41下方に傾斜状外周面43を形成して、ベアリング30の外輪31の端部33と当接させる。この際、係止面41の下方に略円錐台形状又は略円錐形状の軸部42を形成することで、曲面状の傾斜状外周面43を提供してもよく、または短棒状の軸部42に曲面状または平面状の傾斜状外周面43を適宜形成することで備えてもよい。さらに、図4を参照して説明したように、傾斜状外周面43は任意の範囲内に限り備えられることができる。例えば、図8の(D)の符合Tから理解できるように、切削加工により、軸部42の一部を取り除くことで、傾斜状外周面43の範囲を部分的に調整させてもよい。
Here, the external shape of the locking member 40 will be described in more detail.
In particular, FIG. 8 shows (A) a perspective view from above and (B) a perspective view from below of a locking member 40 having a shape that combines the features shown in FIGS. 1 to 3 and the features shown in FIG. The figure, (C) top view and (D) bottom view are shown, respectively. 9A and 9B show a cross-sectional view taken along the line m-m in FIG. 8A and a cross-sectional view taken along the line nn, respectively. As can be understood from these drawings, the locking member 40 is basically formed in a short bar shape so as to protrude from the engagement hole 26 of the holder 20. Preferably, the locking member 40 is formed in a piece shape.
Further, preferably, as shown in FIG. 8A, the locking surface 41 of the locking member 40 that directly presses the paper tube B (see FIG. 1) is used as the outer surface 21 of the holder 20 (see FIG. 5). It forms so that it may curve along. At this time, even when the locking surface 41 is formed so that the locking surface 41 is aligned with the outer surface 21 of the holder 20 (see FIG. 1) when the locking member 40 is immersed in the outer surface 21 of the holder 20. Alternatively, the locking surface 41 may be formed such that the locking surface 41 is somewhat immersed inside the outer surface 21. In the latter case, there is an advantage that the engaging surface 41 does not protrude from the outer surface 21 and the friction is small in operation. Furthermore, as described with reference to FIGS. 1 to 3, the height of the locking surface 41 can be variously changed. For example, as can be understood from the reference S in FIG. 8A, the height of the locking surface 41 may be partially reduced by removing a part of the locking surface 41 by cutting.
Preferably, an inclined outer peripheral surface 43 is formed below the locking surface 41 and brought into contact with the end 33 of the outer ring 31 of the bearing 30. At this time, a substantially frustoconical or substantially conical shaft portion 42 may be formed below the locking surface 41 to provide a curved inclined outer peripheral surface 43, or a short rod-shaped shaft portion 42. Alternatively, a curved or flat inclined outer peripheral surface 43 may be formed as appropriate. Furthermore, as described with reference to FIG. 4, the inclined outer peripheral surface 43 can be provided only within an arbitrary range. For example, as can be understood from the symbol T in FIG. 8D, the range of the inclined outer peripheral surface 43 may be partially adjusted by removing a part of the shaft portion 42 by cutting.

好適には、図5と8の(A)に示すように、係止部材40は、ホルダ20の外表面21上で非固定状態、つまり着脱自在に収容されるため、好適にはホルダ20と係止部材40の各々の外表面に渡るように溝部28、溝部48を形成する。これら溝部28、48内には、弾性部材18(図2、12参照)が挿通されて、係止部材40をホルダ20の係合孔26内に押圧させる。具体的には、弾性部材18は細長く螺旋状に延びるばねである。しかしながら弾性部材18としてばね以外に、弾性を有する紐やOリング等を使用することは可能である。ただし、これら弾性部材18の弾力の大きさは、突出した係止部材40を没入状態に戻す作用を有し、また係止部材40の突出操作に支障を与えないものとする。   Preferably, as shown in FIGS. 5 and 8 (A), the locking member 40 is housed in an unfixed state, that is, detachably on the outer surface 21 of the holder 20. A groove 28 and a groove 48 are formed so as to extend over the outer surfaces of the locking members 40. The elastic members 18 (see FIGS. 2 and 12) are inserted into the grooves 28 and 48 to press the locking member 40 into the engagement hole 26 of the holder 20. Specifically, the elastic member 18 is a spring that is elongated and spirals. However, it is possible to use an elastic string or an O-ring other than the spring as the elastic member 18. However, the magnitude of the elasticity of these elastic members 18 has the effect of returning the protruding locking member 40 to an immersive state and does not hinder the protruding operation of the locking member 40.

上述したように、係止部材40は係止面41の形状を変えることで、ホルダの外表面21からの係止面41の突出高さを細かく調整することができる。例えば、図9の(A)に示すように、係止部材40の係止面41の中央に、弾性部材18を取付けるための溝部48を形成する場合には、この溝部48を境にして、左右の係止面41の高さを変えるように、係止部材40の突出高さを調整してもよい。図9の(A)に示したものでは、係止部材40は左側の係止面41の高さに比べて、右側の係止面41の高さを低くして(符合S参照)、突出時に左側の係止面41が紙管の内面を押圧するとき、右側の係止面41が紙管の内面との間にギャップを設けるようにしている。このギャップの大きさは、実施形態によって適宜定めることができる。但し、このように係止部材40の高さを部分的に変更させても、溝部48による弾性部材18を保持する機能が損われないようにする。   As described above, the locking member 40 can finely adjust the protrusion height of the locking surface 41 from the outer surface 21 of the holder by changing the shape of the locking surface 41. For example, as shown in FIG. 9A, when a groove 48 for attaching the elastic member 18 is formed at the center of the locking surface 41 of the locking member 40, the groove 48 is used as a boundary. The protruding height of the locking member 40 may be adjusted so as to change the height of the left and right locking surfaces 41. In the case shown in FIG. 9A, the locking member 40 protrudes with the height of the right locking surface 41 lower than the height of the left locking surface 41 (see symbol S). When the left locking surface 41 sometimes presses the inner surface of the paper tube, a gap is provided between the right locking surface 41 and the inner surface of the paper tube. The size of the gap can be appropriately determined according to the embodiment. However, even if the height of the locking member 40 is partially changed in this way, the function of holding the elastic member 18 by the groove 48 is not impaired.

図9の(A)に示す例では、係止部材40の係止面41の右側の高さを低くする(符合S参照)とともに、これと反対側の、左側の軸部42の傾斜状外周面43の一部を取り除いている(符合T参照)。この場合、係止部材40は、右側の傾斜状外周面43からベアリング30と直接当接して、右側からベアリング30を軸方向にスライドさせると、係止部材40は右側の傾斜状外周面43に沿って放射方向に突出する。但し、係止面41の右側の高さを低くしているため、係止部材40は左側から紙管Bを押圧する。一方、係止部材40に対して左側からベアリング30を軸方向にスライドさせると、この側では傾斜状外周面43が取り除かれていることにより、ベアリング30の外輪31と係止部材40が直接当接しないため、ベアリング30のスライドに係らず、係止部材40はホルダ20内に収容されたままになる。
これに対して、図10の(B)に示すように、係止部材40の係止面41の左側の高さを低くする(符合S参照)とともに、これと同じ側の、左側の軸部42の傾斜状外周面43の一部を取り除くようにしてもよい(符合T参照)。この場合、係止部材40は、右側の傾斜状外周面からベアリング30と直接当接して、右側からベアリング30を軸方向にスライドさせると、係止部材40は右側の傾斜状外周面43に沿って放射方向に突出する。但し、係止面41の左側の高さを低くしているため、係止部材40は右側から紙管Bを押圧する。一方、係止部材40に対して左側からベアリング30を軸方向にスライドさせると、この側では傾斜状外周面43が取り除かれていることにより、ベアリング30の外輪31と係止部材40が直接当接しないため、ベアリング30のスライドに係らず、係止部材40はホルダ20内に収容されたままになる。
図9と10に示した構成は、夫々左右逆、つまり鏡像関係となるように構成することができる。これは、単にホルダ20内に収容する係止部材40の向きを180°変えることで達成できる。
In the example shown in FIG. 9A, the height of the right side of the locking surface 41 of the locking member 40 is lowered (see reference S), and the inclined outer periphery of the left shaft portion 42 on the opposite side. A part of the surface 43 is removed (see symbol T). In this case, when the locking member 40 comes into direct contact with the bearing 30 from the right inclined outer peripheral surface 43 and the bearing 30 is slid in the axial direction from the right side, the locking member 40 contacts the right inclined outer peripheral surface 43. Project radially. However, since the height on the right side of the locking surface 41 is lowered, the locking member 40 presses the paper tube B from the left side. On the other hand, when the bearing 30 is slid in the axial direction from the left side with respect to the locking member 40, the inclined outer peripheral surface 43 is removed on this side, so that the outer ring 31 of the bearing 30 and the locking member 40 directly contact each other. Therefore, the locking member 40 remains accommodated in the holder 20 regardless of the slide of the bearing 30.
On the other hand, as shown in FIG. 10B, the left-side height of the locking surface 41 of the locking member 40 is lowered (see symbol S), and the left side shaft portion on the same side as this is shown. A part of the inclined outer peripheral surface 43 of 42 may be removed (see symbol T). In this case, when the locking member 40 is brought into direct contact with the bearing 30 from the right inclined outer peripheral surface and the bearing 30 is slid in the axial direction from the right side, the locking member 40 follows the right inclined outer peripheral surface 43. Projecting radially. However, since the left side height of the locking surface 41 is lowered, the locking member 40 presses the paper tube B from the right side. On the other hand, when the bearing 30 is slid in the axial direction from the left side with respect to the locking member 40, the inclined outer peripheral surface 43 is removed on this side, so that the outer ring 31 of the bearing 30 and the locking member 40 directly contact each other. Therefore, the locking member 40 remains accommodated in the holder 20 regardless of the slide of the bearing 30.
The configurations shown in FIGS. 9 and 10 can be configured to be opposite to each other, that is, to have a mirror image relationship. This can be achieved simply by changing the direction of the locking member 40 accommodated in the holder 20 by 180 °.

このように、本発明では、係止面41の形状を変化させた係止部材40(図1〜3参照)と、傾斜状外周面43の形状を変化させた係止部材40(図4参照)と、係止面41と傾斜状外周面43の形状を変化させた係止部材40(図8〜10参照)を提供する。これら係止部材40は、紙管ホルダ10の係合孔26から任意に着脱自在に取付けられる。この取付けは、実施形態に合わせて柔軟に変更することができるため、紙管ホルダ10と紙管BのピッチPO、P2が相違する結果、紙管ホルダ10上に紙管Bがずれて配置されるような場合(図13参照)であっても、位置ずれは予測できるので、個々の紙管ホルダ10による係止部材40の突出状態を細かく調整することで、夫々の位置ずれに合わせて、柔軟に巻取操作を行えるようにする。従って、巻取装置100によって巻き取られる紙管Bの幅は、従来のように限定されず、格段に広げられており、基本的には、ほとんどの幅の紙管Bを巻き取ることが可能になる。 Thus, in the present invention, the locking member 40 (see FIGS. 1 to 3) in which the shape of the locking surface 41 is changed, and the locking member 40 (see FIG. 4) in which the shape of the inclined outer peripheral surface 43 is changed. ), And a locking member 40 (see FIGS. 8 to 10) in which the shapes of the locking surface 41 and the inclined outer peripheral surface 43 are changed. These locking members 40 are attached to the paper tube holder 10 from the engagement holes 26 as desired. Since this attachment can be flexibly changed in accordance with the embodiment, the pitches P O and P 2 between the paper tube holder 10 and the paper tube B are different, and as a result, the paper tube B is displaced on the paper tube holder 10. Even in the case of being arranged (see FIG. 13), the positional deviation can be predicted. Therefore, by adjusting the protruding state of the locking member 40 by the individual paper tube holder 10, it can be adjusted to each positional deviation. The winding operation can be performed flexibly. Therefore, the width of the paper tube B taken up by the take-up device 100 is not limited as in the prior art, and has been greatly expanded. Basically, it is possible to wind up the paper tube B of almost all widths. become.
