図4の缶蓋巻締機は、シーミングヘッド101と、シーミングスピンドル102と、ノックアウトロッド103と、シーミングロール104と、リフター105を備えている。シーミングヘッド101は、図示しない左側の軸を中心として公転するように構成されている。シーミングヘッド101の公転軌道の円周方向に、複数のシーミングスピンドル102が等間隔で配置され、シーミングヘッド101に対して各シーミングスピンドル102が、転がり軸受106により回転(自転)自在に支持されている。
The can lid winding machine is a device that fixes the lid to the main body by putting beer or juice into the main body (body) of the can and then winding and tightening the peripheral edge of the lid on the upper edge of the main body, For example, what is shown in FIG. 4 is mentioned (refer the following patent document 1).
The can lid winding machine in FIG. 4 includes a seaming head 101, a seaming spindle 102, a knockout rod 103, a seaming roll 104, and a lifter 105. The seaming head 101 is configured to revolve around a left axis (not shown). A plurality of seaming spindles 102 are arranged at equal intervals in the circumferential direction of the revolution track of the seaming head 101, and each seaming spindle 102 can be rotated (rotated) by a rolling bearing 106 with respect to the seaming head 101. It is supported.

シーミングヘッド101の転がり軸受106の上部には、潤滑油のオイルタンクとなる空間101aが設けてあり、この空間(オイルタンク)101aから転がり軸受106に潤滑油が供給される。転がり軸受106の下端には、クランプリング107によりオイルシール108が取り付けられている。
シーミングスピンドル102は、最も下側に配置された転がり軸受106の内輪の下端面を保持するフランジ102aを有し、このフランジ102aより先端側の外径が基端側より小さく形成されている。この小径部102bにスリーブ109とカラー110が外嵌されている。スリーブ109とカラー110は、内面に溝を設けてこの溝にOリング111を取り付けることにより、シーミングスピンドル102の小径部102bに強固に外嵌されている。
A space 101a serving as an oil tank for lubricating oil is provided above the rolling bearing 106 of the seaming head 101, and the lubricating oil is supplied to the rolling bearing 106 from this space (oil tank) 101a. An oil seal 108 is attached to the lower end of the rolling bearing 106 by a clamp ring 107.
The seaming spindle 102 has a flange 102a that holds the lower end surface of the inner ring of the rolling bearing 106 arranged on the lowermost side, and the outer diameter on the distal end side of the flange 102a is smaller than that on the proximal end side. A sleeve 109 and a collar 110 are fitted on the small diameter portion 102b. The sleeve 109 and the collar 110 are firmly fitted onto the small diameter portion 102b of the seaming spindle 102 by providing a groove on the inner surface and attaching an O-ring 111 to the groove.

このスリーブ109のフランジ102a側の外周面が、オイルシール108のリップ部が接触する摺接面となっている。カラー110はスリーブ109の位置調整用のスペーサ(シーミングチャック112とスリーブ109との間を埋めるもの)として配置されている。そして、シーミングスピンドル102の最も先端(小径部102bよりさらに外径が小さい部分)の外周面に、シーミングチャック112が螺合されている。   The outer peripheral surface of the sleeve 109 on the flange 102a side is a sliding contact surface with which the lip portion of the oil seal 108 contacts. The collar 110 is arranged as a spacer for adjusting the position of the sleeve 109 (filling between the seaming chuck 112 and the sleeve 109). A seaming chuck 112 is screwed onto the outer peripheral surface of the most distal end of the seaming spindle 102 (portion having a smaller outer diameter than the small diameter portion 102b).

シーミングスピンドル102には、ガイドリング113を介してノックアウトロッド103が内挿され、ノックアウトロッド103の先端に、缶の蓋121を押さえるパッド103aが設けてある。
シーミングロール104は、図示しないシーミングシャンクシャフト下端に支持されたシーミングレバー114により、リフター105に置かれた缶の胴122に向かって接近するように、また公転および自転自在となるように支持されている。
A knockout rod 103 is inserted into the seaming spindle 102 via a guide ring 113, and a pad 103 a for holding the can lid 121 is provided at the tip of the knockout rod 103.
The seaming roll 104 is approached toward the can body 122 placed on the lifter 105 by a seaming lever 114 supported by a lower end of a seaming shank shaft (not shown), and can be revolved and rotated. It is supported.

この缶蓋巻締機は以下のように駆動する。
手前の工程で、缶の胴122内にビールやジュースなどの液体が入り、その上に蓋121を載せたものが、リフター105の上に置かれている。先ず、このリフター105が、シーミングスピンドル102の下方に配されて、上昇し、シーミングチャック112が蓋121の外縁部と胴122の上端縁部を押さえる。
This can lid winding machine is driven as follows.
In the foreground process, a liquid such as beer or juice enters the can body 122, and a lid 121 is placed on the top of the lifter 105. First, the lifter 105 is disposed below the seaming spindle 102 and ascends, and the seaming chuck 112 presses the outer edge of the lid 121 and the upper edge of the barrel 122.

次に、ノックアウトロッド103の先端のパッド103aを蓋121に押し当てる。次に、シーミングロール104をチャック112に接近させて、シーミングスピンドル102を回転させるとともに、シーミングロール104を回転させることにより、蓋121の周縁部を胴122の上端縁部に巻き締め固定する。
このような缶蓋巻締機では、上方のオイルタンク101aから潤滑油が転がり軸受106に供給されており、潤滑油が漏れると下側に配置された缶に付着する恐れがあるため、オイル漏れを確実に防止する必要がある。そのために、オイルシール108を取り付けるとともに、クランプリング107にラビリンスリール107aを設けているが、漏れが生じた場合には缶蓋巻締機の駆動を停止してオイルシール108を交換する必要がある。
Next, the pad 103 a at the tip of the knockout rod 103 is pressed against the lid 121. Next, the seaming roll 104 is moved closer to the chuck 112 to rotate the seaming spindle 102 and the seaming roll 104 is rotated so that the peripheral edge of the lid 121 is fastened to the upper edge of the barrel 122. To do.
In such a can lid winding machine, the lubricating oil is supplied to the rolling bearing 106 from the upper oil tank 101a, and if the lubricating oil leaks, there is a risk of adhering to the lower can. It is necessary to reliably prevent this. For this purpose, an oil seal 108 is attached and a labyrinth reel 107a is provided on the clamp ring 107. However, if leakage occurs, it is necessary to stop driving the can lid winding machine and replace the oil seal 108. .

オイルシール108の交換時には、スリーブ109とカラー110が存在しない状態で新しいオイルシール108を取り付ける必要がある。そのため、シーミングスピンドル102からシーミングチャック112とスリーブ109とカラー110を外す作業が必要となる。
シーミングチャック112は、シーミングスピンドル102の先端部に螺合されているため、その取り外しは特に問題なくできる。しかし、スリーブ109とカラー110は、内面の溝にOリング111を入れて、シーミングスピンドル102に強固に取り付けられているため、簡単に引き抜くことができない。
When the oil seal 108 is replaced, it is necessary to install a new oil seal 108 in a state where the sleeve 109 and the collar 110 are not present. Therefore, it is necessary to remove the seaming chuck 112, the sleeve 109, and the collar 110 from the seaming spindle 102.
Since the seaming chuck 112 is screwed to the tip of the seaming spindle 102, the removal thereof can be performed without any particular problem. However, since the sleeve 109 and the collar 110 are firmly attached to the seaming spindle 102 with an O-ring 111 inserted into the groove on the inner surface, they cannot be easily pulled out.

そのため、スリーブ109とカラー110を取り外す作業に時間がかかったり、プーリー抜きなどの道具で無理に引き抜こうとして、外周面に傷を付けたりする恐れがある。特に、スリーブ109のオイルシール108が摺接する面に傷が付くと、そのスリーブ109を使用できなくなる。
下記の特許文献2には、回転軸に圧挿されるインナーレース外周の環状溝にスナップリングが嵌挿された軸受のインナーレースを、前記回転軸から取り外す軸受のインナーレース取り外し装置が提案されている。この装置は、前記インナーレースの外周を径方向に挟み込む複数に分割された挟持部材と、前記挟持部材の一側に設けられ前記スナップリングに係合する係合部と、複数の連結部材を介して前記挟持部材に連結され中心部にねじ穴が貫設された支持部材と、抜出し用ボルトと、を備えている。
For this reason, it may take time to remove the sleeve 109 and the collar 110, or the outer peripheral surface may be damaged if the sleeve 109 and the collar 110 are forcibly pulled out with a tool such as a pulley remover. In particular, if the surface of the sleeve 109 where the oil seal 108 comes into sliding contact is damaged, the sleeve 109 cannot be used.
Patent Document 2 below proposes an inner race removing device for a bearing that removes an inner race of a bearing in which a snap ring is inserted into an annular groove on the outer periphery of the inner race that is press-fitted into the rotating shaft from the rotating shaft. . The apparatus includes a plurality of divided clamping members that sandwich the outer periphery of the inner race in the radial direction, an engaging portion that is provided on one side of the clamping member and engages with the snap ring, and a plurality of connecting members. And a support member connected to the clamping member and having a screw hole penetrating in the center thereof, and an extraction bolt.

この発明のスリーブ取り外し装置を使用する際には、先ず、前記ネジ棒部材の前記板状部材から前記分割体側への突出量を少なくする。また、前記固定部材による前記棒状部材の先端の前記板状部材の連結部に対する固定を緩めて、前記連結部における前記棒状部材の先端の位置を、前記複数の分割体同士の間隔が拡がる位置に調整する。
この状態で、前記板状部材をシーミングスピンドルの先端側に配置し、前記複数の分割体の内周面を、シーミングスピンドルに外嵌されているスリーブの外周面に接触させる。その際に、前記棒状部材の先端の位置は前記連結部で調整される。この状態で、各分割体を結合部材で結合する。前記棒状部材の長さはこの状態が実現できる長さとする。これにより、前記スリーブが前記外包部材で接触支持される。ここで、外包部材で接触支持する位置を、スリーブの外周面のオイルシール摺動面でない部分にすることで、スリーブのオイルシール摺接面に傷を付けることが防止できる。
When using the sleeve detaching device of the present invention, first, the protruding amount of the screw rod member from the plate-like member to the divided body side is reduced. Further, the fixing of the tip of the rod-shaped member by the fixing member to the connecting portion of the plate-like member is loosened, and the position of the tip of the rod-shaped member in the connecting portion is set to a position where the interval between the plurality of divided bodies is expanded. adjust.
In this state, the plate-like member is disposed on the tip end side of the seaming spindle, and the inner peripheral surfaces of the plurality of divided bodies are brought into contact with the outer peripheral surface of the sleeve fitted on the seaming spindle. In that case, the position of the front-end | tip of the said rod-shaped member is adjusted with the said connection part. In this state, each divided body is coupled by a coupling member. The length of the rod-shaped member is a length that can realize this state. Thereby, the sleeve is contact-supported by the outer packet member. Here, it is possible to prevent the oil seal slidable contact surface of the sleeve from being scratched by setting the position of contact support by the outer packet member to a portion that is not the oil seal sliding surface of the outer peripheral surface of the sleeve.

次に、前記ハンドルを操作して前記ネジ棒部材を回すことにより、前記板状部材よりシーミングスピンドル側に前記芯出し部材を進ませて、前記芯出し部材の突起をシーミングスピンドルの先端部内に挿入し、前記芯出し部材の端面をシーミングスピンドルの先端面に当てる。これにより、シーミングスピンドルと前記ネジ棒部材の芯出しが行われる。
次に、前記固定部材により前記棒状部材の先端を前記板状部材の前記連結部に固定する。
この状態で、前記ネジ棒部材をさらに同じ向きに回し続けることで、前記芯出し部の端面がシーミングスピンドルの端面に強く押し付けられ、ネジ棒部材がシーミングスピンドル側に移動できなくなると、ネジ棒部材が螺合している雌ねじを有する板状部材が、ハンドル側に移動する。これに伴って、前記板状部材に固定されている前記棒状部材とともに前記外包部材もハンドル側に移動する。この外包部材で前記スリーブが支持されているため、このスリーブもハンドル側に移動する。
Next, by operating the handle and rotating the screw rod member, the centering member is advanced from the plate-like member to the seaming spindle side, and the protrusion of the centering member is moved into the tip of the seaming spindle. And the end surface of the centering member is brought into contact with the front end surface of the seaming spindle. Thereby, the centering of the seaming spindle and the screw rod member is performed.
Next, the tip of the bar-like member is fixed to the connecting portion of the plate-like member by the fixing member.
In this state, by continuing to rotate the screw rod member in the same direction, the end surface of the centering portion is strongly pressed against the end surface of the seaming spindle, and the screw rod member cannot move to the seaming spindle side. A plate-like member having a female screw with which the bar member is screwed moves to the handle side. Along with this, the outer packet member also moves to the handle side together with the rod-shaped member fixed to the plate-shaped member. Since the sleeve is supported by the outer packet member, the sleeve also moves to the handle side.

そして、前記ネジ棒部材の長さを、取り外し対象となるスリーブの軸方向寸法とそのシーミングスピンドルに対する外嵌位置に応じて、前記移動によりスリーブがシーミングスピンドルの外嵌位置から外せる長さにしておくことで、前記移動により前記スリーブがシーミングスピンドルから取り外される。   Then, the length of the screw rod member is set such that the sleeve can be removed from the outer fitting position of the seaming spindle by the movement according to the axial dimension of the sleeve to be removed and the outer fitting position of the screw rod member. Thus, the sleeve is removed from the seaming spindle by the movement.

板状部材3の平面形状はほぼ短冊状であって、その中央に、板面を貫通する雌ねじ31が形成され、その周辺である長手方向両端部(雌ねじ31を挟んで径方向に沿った位置)に、長穴(連結部)32が形成されている。長穴32の長手方向は板状部材3の長手方向に合わせてある。そして、棒状部材2の上端を、板状部材3の各長穴32に入れ、その雌ねじ孔22にワッシャー24を介して止めネジ25を螺合することで、棒状部材2の上端が板状部材3に固定される。   The planar shape of the plate-like member 3 is substantially strip-shaped, and a female screw 31 that penetrates the plate surface is formed at the center thereof, and both ends in the longitudinal direction (positions along the radial direction across the female screw 31). ), A long hole (connecting portion) 32 is formed. The longitudinal direction of the long hole 32 is matched with the longitudinal direction of the plate-like member 3. Then, the upper end of the rod-shaped member 2 is put into each elongated hole 32 of the plate-shaped member 3 and the set screw 25 is screwed into the female screw hole 22 via the washer 24 so that the upper end of the rod-shaped member 2 is the plate-shaped member. 3 is fixed.

止めネジ25を締めて棒状部材2が板状部材3の長穴32に固定されている状態から止めネジ25を緩めることで、板状部材3の長穴32に対する棒状部材2の先端部の位置調整ができ、位置を決めた状態で止めネジ25を締めれば、棒状部材2をその位置に固定することができる。この位置調整により半円環状部材11,12の向かい合う端面の間隔が変更できる。   By tightening the set screw 25 and loosening the set screw 25 from the state in which the rod-like member 2 is fixed to the elongated hole 32 of the plate-like member 3, the position of the tip of the rod-like member 2 with respect to the elongated hole 32 of the plate-like member 3 If the set screw 25 is tightened in a state where the position can be adjusted, the rod-shaped member 2 can be fixed at that position. By this position adjustment, the distance between the end faces of the semi-annular members 11, 12 can be changed.

ネジ棒部材4の長さ方向両端部は小径部となっていて、両小径部に雌ねじ孔が形成されている。このネジ棒部材4が板状部材3の雌ねじ31に螺合されていて、円環状部材1側に突出する側の先端に芯出し部品6が、反対側の先端に円板状のハンドル7が取り付けられている。ハンドル7をなす円板は中心孔を有し、この中心孔とネジ棒部材4の小径部の雌ねじ孔とを合わせてハンドル7側から止めネジ71を螺合することで、ハンドル7はネジ棒部材4に固定されている。   Both ends in the length direction of the screw rod member 4 are small diameter portions, and female screw holes are formed in both small diameter portions. The threaded rod member 4 is screwed into the female screw 31 of the plate-like member 3, and a centering component 6 is provided at the tip of the annular member 1 and the disc-like handle 7 is provided at the tip of the opposite side. It is attached. The disc forming the handle 7 has a center hole, and the center hole and the female screw hole of the small-diameter portion of the screw rod member 4 are aligned with each other, and the set screw 71 is screwed from the handle 7 side. It is fixed to the member 4.

芯出し部品6は大径部61と小径部62とからなり、先端の小径部62がシーミングスピンドルの先端部内に挿入される突起である。大径部61の小径部62側の端面61aがシーミングスピンドルの先端面に押し当てる部分である。図3に示すように、芯出し部品6の中心に、ネジ棒部材4の小径部41に対して緩みを有する寸法の貫通孔63が形成されている。   The centering component 6 includes a large-diameter portion 61 and a small-diameter portion 62, and the small-diameter portion 62 at the tip is a protrusion that is inserted into the tip of the seaming spindle. The end surface 61a on the small diameter portion 62 side of the large diameter portion 61 is a portion that presses against the tip surface of the seaming spindle. As shown in FIG. 3, a through hole 63 having a size that is loose with respect to the small diameter portion 41 of the screw rod member 4 is formed at the center of the centering component 6.

芯出し部品6はネジ棒部材4に対して、止めネジ65とその座面を有するワッシャー66を用いて取り付けられている。すなわち、図3に示すように、芯出し部品6の大径部61側から貫通孔63にネジ棒部材4の小径部41が挿入され、芯出し部品6の小径部62にワッシャー66を重ねた状態でワッシャー66側から挿入された止めネジ65が、ネジ棒部材4の小径部41の雌ねじ孔に螺合している。   The centering component 6 is attached to the screw rod member 4 using a set screw 65 and a washer 66 having a seating surface. That is, as shown in FIG. 3, the small diameter portion 41 of the screw rod member 4 is inserted into the through hole 63 from the large diameter portion 61 side of the centering component 6, and the washer 66 is overlapped on the small diameter portion 62 of the centering component 6. The set screw 65 inserted from the washer 66 side in the state is screwed into the female screw hole of the small diameter portion 41 of the screw rod member 4.

止めネジ65を締めた状態で、ワッシャー66と芯出し部品6との間に隙間があり、ネジ棒部材4の小径部41と芯出し部品6との間にも隙間がある。これにより、ネジ棒部材4が回転した時に、ワッシャー66は一緒に回転するが、芯出し部品6は回転しない。このようにして、芯出し部品6はネジ棒部材4の先端に、ネジ棒部材4の回転を許容するように取り付けられている。   With the set screw 65 tightened, there is a gap between the washer 66 and the centering component 6, and there is also a gap between the small diameter portion 41 of the screw rod member 4 and the centering component 6. Thereby, when the screw rod member 4 rotates, the washer 66 rotates together, but the centering component 6 does not rotate. In this way, the centering component 6 is attached to the tip of the screw rod member 4 so as to allow the screw rod member 4 to rotate.

この実施形態のスリーブ取り外し装置は例えば以下の方法で使用することができる。
先ず、ネジ棒部材4の板状部材3から円環状部材1側への突出量を少なくして、図1および2に示す状態から、ボルト13を外して外包部材1を半円環状部材11,12に分割し、止めネジ25を緩めて棒状部材2を板状部材3の長穴32に対して移動可能な状態にする。
The sleeve removing apparatus of this embodiment can be used, for example, by the following method.
First, the amount of protrusion of the screw rod member 4 from the plate-like member 3 to the annular member 1 side is reduced, and the bolt 13 is removed from the state shown in FIGS. 12 and the set screw 25 is loosened so that the rod-like member 2 is movable with respect to the elongated hole 32 of the plate-like member 3.

次に、図4に示す缶蓋巻締機のシーミングスピンドル102から、シーミングチャック112を外す。この状態で、図3(A)に示すように、ハンドル7を下側に向け、板状部材3をシーミングスピンドル102の下側に配置し、半円環状部材11,12でシーミングスピンドル102に外嵌されているスリーブ109の外周側を囲う。その際に、棒状部材2の下端部は長穴32に沿って移動する。
この状態で、半円環状部材12の貫通孔12bから挿入したボルト13の先端を、半円環状部材11の雌ねじ孔11bに螺合する。これにより、半円環状部材11,12が結合されて円環状部材1となり、その内周面10がスリーブ109の外周面に接触し、円環状部材1でスリーブ109が支持された状態となる。
Next, the seaming chuck 112 is removed from the seaming spindle 102 of the can lid winding machine shown in FIG. In this state, as shown in FIG. 3A, the handle 7 is directed downward, the plate-like member 3 is disposed below the seaming spindle 102, and the seaming spindle 102 is formed by the semi-annular members 11 and 12. The outer periphery side of the sleeve 109 that is fitted on the outer periphery of the sleeve 109 is enclosed. At that time, the lower end portion of the rod-shaped member 2 moves along the elongated hole 32.
In this state, the tip of the bolt 13 inserted from the through hole 12 b of the semi-annular member 12 is screwed into the female screw hole 11 b of the semi-annular member 11. As a result, the semi-annular members 11 and 12 are joined to form the annular member 1, and the inner peripheral surface 10 contacts the outer peripheral surface of the sleeve 109, and the sleeve 109 is supported by the annular member 1.

次に、ハンドル7を回して、ネジ棒部材4を上向きに回転させることにより、先端のワッシャー66と芯出し部品6の小径部62をシーミングスピンドル102の先端部内に挿入し、芯出し部品6の大径部61の端面61aをシーミングスピンドル102の先端面に当てる。その際に、棒状部材2の下端部が長穴32に沿って移動することで、板状部材3に対する位置調整がなされる。
これにより、シーミングスピンドル102とネジ棒部材4の芯出しが行われる。次に、止めネジ25を締めて、棒状部材2の下端部を板状部材3の長穴32に対して固定する。図3(A)はこの状態を示している。
Next, the handle 7 is turned to rotate the screw rod member 4 upward, thereby inserting the washer 66 at the tip and the small diameter portion 62 of the centering component 6 into the tip of the seaming spindle 102. The end surface 61 a of the large-diameter portion 61 is brought into contact with the tip surface of the seaming spindle 102. At that time, the lower end portion of the rod-shaped member 2 moves along the long hole 32, so that the position of the plate-shaped member 3 is adjusted.
Thereby, the centering of the seaming spindle 102 and the screw rod member 4 is performed. Next, the set screw 25 is tightened to fix the lower end portion of the rod-like member 2 to the long hole 32 of the plate-like member 3. FIG. 3A shows this state.

この状態からさらに、ハンドル7を同じ向きに回し続けて、ネジ棒部材4を上向きに回転させ続ける。これに伴い、芯出し部品6の大径部61の端面61aがシーミングスピンドル102の端面に強く押し付けられて、ネジ棒部材4が上昇できなくなると、ネジ棒部材4が螺合している雌ねじ31を有する板状部材3が下降する。これに伴って、板状部材3に固定されている棒状部材2とともに円環状部材1が下降する。この円環状部材1の下降に伴って、スリーブ109とその下方のカラー110がシーミングスピンドル102から取り外される。図3(B)はこの状態を示している。   From this state, the handle 7 is continuously rotated in the same direction, and the screw rod member 4 is continuously rotated upward. Accordingly, when the end surface 61a of the large-diameter portion 61 of the centering component 6 is strongly pressed against the end surface of the seaming spindle 102 and the screw rod member 4 cannot be raised, the female screw into which the screw rod member 4 is screwed. The plate-like member 3 having 31 descends. Accordingly, the annular member 1 moves down together with the rod-like member 2 fixed to the plate-like member 3. As the annular member 1 is lowered, the sleeve 109 and the collar 110 below the sleeve 109 are removed from the seaming spindle 102. FIG. 3B shows this state.

そして、この取り外しの際に、円環状部材1は、スリーブ109のオイルシール108が摺動している面より下側の部分を接触支持しているため、スリーブ109のオイルシール摺動面に傷が生じない。
この実施形態のスリーブ取り外し装置は、上述のように、図4に示す缶蓋巻締機からシーミングスピンドル102を外さない状態で、シーミングスピンドル102からスリーブ109とその下方のカラー110を外すことができる。
