本発明の清掃用シート巻取軸体の一実施の形態を図面を参照して説明する。   An embodiment of a cleaning sheet winding shaft according to the present invention will be described with reference to the drawings.

図３において、１はブランケット胴清掃装置で、このブランケット胴清掃装置１は、シート供給体２から順次供給される清掃用シートＳを輪転機のブランケット胴３の円筒面状の外周面の一部に圧着パッド４で押し当ててこのブランケット胴３の外周面を清掃し、ブランケット胴３の外周面に付着したインキや紙粉等の汚れを除去するものである。   In FIG. 3, reference numeral 1 denotes a blanket cylinder cleaning device. This blanket cylinder cleaning device 1 is a part of a cylindrical outer peripheral surface of a blanket cylinder 3 of a rotary press for cleaning sheets S sequentially supplied from a sheet supply body 2. The blanket cylinder 3 is pressed against the outer peripheral surface of the blanket cylinder 3 to clean the outer peripheral surface of the blanket cylinder 3 to remove stains such as ink and paper powder adhering to the outer peripheral surface of the blanket cylinder 3.

清掃用シートＳは、例えば洗浄液を含浸した不織布等の洗浄布で、ブランケット胴３の軸方向長さ寸法に対応した幅寸法を有する幅広状に形成されている。そして、ブランケット胴３の外周面に押し当てられて汚れた清掃用シートＳは、図示しない軸支持手段にて回転可能に支持された清掃用シート巻取軸体５にてロール状に巻き取られる。   The cleaning sheet S is, for example, a cleaning cloth such as a nonwoven fabric impregnated with a cleaning liquid, and is formed in a wide shape having a width dimension corresponding to the axial length of the blanket cylinder 3. Then, the cleaning sheet S that is pressed and soiled against the outer peripheral surface of the blanket cylinder 3 is wound up in a roll shape by a cleaning sheet winding shaft 5 that is rotatably supported by a shaft support means (not shown). .

ここで、清掃用シート巻取軸体５は、図１および図２に示すように、軸方向に長手状の開口部10を有する断面略Ｃ字状の金属製の筒状部材11と、この筒状部材11の内周側にこの筒状部材11に対して回転可能に嵌合され筒状部材11と同心状に位置し外周側に軸方向に長手状の切欠部13を有する金属製の軸状部材12とを備えている。   Here, as shown in FIGS. 1 and 2, the cleaning sheet take-up shaft 5 includes a metal cylindrical member 11 having a substantially C-shaped cross section having a longitudinal opening 10 in the axial direction. A metallic member having a notch 13 that is axially elongated on the outer peripheral side of the cylindrical member 11 that is rotatably fitted to the cylindrical member 11 and is positioned concentrically with the cylindrical member 11. A shaft-like member 12 is provided.

そして、清掃用シート巻取軸体５は、汚れた清掃用シートＳの巻き取り時には、軸状部材12の筒状部材11に対する一方向への相対的な回転、例えば約１３０度の回転により軸状部材12の外周側一部が開口部10から突出した外形略円形状の軸径大状態になり、ロール状に巻き取られた清掃用シートＳの取り外し時には、軸状部材12の筒状部材11に対する他方向への相対的な回転、例えば約１３０度の回転により軸状部材12が開口部10から突出しない外形非円形状の軸径小状態になる。   When the dirty cleaning sheet S is wound up, the cleaning sheet take-up shaft 5 is rotated by a relative rotation of the shaft-like member 12 with respect to the tubular member 11 in one direction, for example, a rotation of about 130 degrees. When the cleaning sheet S wound up in a roll shape is removed, a cylindrical member of the shaft-shaped member 12 is formed in a state in which the outer diameter side of the outer member 12 protrudes from the opening 10 and has a substantially circular outer diameter. A relative rotation in the other direction with respect to 11, for example, a rotation of about 130 degrees, causes the shaft-shaped member 12 to be in a non-circular outer shape in which the shaft member 12 does not protrude from the opening 10.

筒状部材11は、清掃用シートＳの幅寸法と略同じかそれより若干長い軸方向長さ寸法を有する両端面開口状で断面略Ｃ字状をなす筒形状に形成されている。筒状部材11は、軸方向両端近傍に位置する周方向に長手状の長孔部15と、この長孔部15の一端に臨んだ第１受部16と、長孔部15の他端に臨んだ第２受部17とを有している。また、筒状部材11の開口部10に臨んだ端部には、清掃用シートＳの先端部を引っ掛けるための角部分19が形成されている。   The cylindrical member 11 is formed in a cylindrical shape having a substantially C-shaped cross section with an opening on both end surfaces having an axial length dimension substantially the same as or slightly longer than the width dimension of the cleaning sheet S. The cylindrical member 11 includes a long hole portion 15 that is long in the circumferential direction located in the vicinity of both ends in the axial direction, a first receiving portion 16 that faces one end of the long hole portion 15, and the other end of the long hole portion 15. And a second receiving portion 17 that is faced. Further, a corner portion 19 for hooking the leading end portion of the cleaning sheet S is formed at the end portion of the cylindrical member 11 facing the opening 10.

軸状部材12は、筒状部材11の軸方向長さ寸法と略同じ軸方向長さ寸法を有する断面切欠円形状の軸本体部21と、この軸本体部21の両端面に突設された円柱状の突出部22，23と、一方の突出部22の端面に突設された略直方体状の係合部24とにて構成されている。   The shaft-shaped member 12 is provided with a shaft body portion 21 having a circular cross-sectional shape having an axial length dimension substantially the same as the axial length dimension of the tubular member 11, and projecting from both end surfaces of the shaft body portion 21. It is comprised by the cylindrical protrusion parts 22 and 23, and the substantially rectangular parallelepiped-shaped engaging part 24 protrudingly provided by the end surface of one protrusion part 22. As shown in FIG.

断面切欠円形状の軸本体部21の外周面が、１つの円弧面部分26と１つの平面部分27とにて構成されている。円弧面部分26は断面略Ｃ字状の筒状部材11に対応する大きさのもので、平面部分27は開口部10に対応する大きさのものである。   The outer peripheral surface of the shaft main body 21 having a circular cross-sectional shape is composed of one arcuate surface portion 26 and one flat surface portion 27. The arcuate surface portion 26 has a size corresponding to the cylindrical member 11 having a substantially C-shaped cross section, and the flat surface portion 27 has a size corresponding to the opening 10.

軸本体部21の円弧面部分26の軸方向両端近傍には断面円形のピン状の突起部30が径方向外方に向って突設され、この突起部30は筒状部材11の長孔部15内に移動可能に挿入されている。突起部30は、軸状部材12の筒状部材11に対する相対的な回転時に筒状部材11の長孔部15内をスライド移動し、清掃用シート巻取軸体５の軸径大状態時には筒状部材11の第１受部16に当接し（図７参照）、清掃用シート巻取軸体５の軸径小状態時には筒状部材11の第２受部17に当接する（図８参照）。   Near the both ends in the axial direction of the arcuate surface portion 26 of the shaft main body 21, a pin-shaped protrusion 30 having a circular cross section protrudes radially outward, and this protrusion 30 is a long hole portion of the tubular member 11. 15 is movably inserted. The protrusion 30 slides in the long hole portion 15 of the cylindrical member 11 when the shaft member 12 is rotated relative to the cylindrical member 11, and the cylindrical portion 11 is in a cylindrical state when the shaft diameter of the cleaning sheet take-up shaft 5 is large. Abuts against the first receiving portion 16 of the cylindrical member 11 (see FIG. 7), and abuts against the second receiving portion 17 of the cylindrical member 11 when the shaft diameter of the cleaning sheet take-up shaft 5 is small (see FIG. 8). .

なお、軸状部材12の両端の突出部22，23は、ブランケット胴清掃装置１の図示しない軸支持手段にて回転可能に支持されている。また、軸状部材12は、係合部24が図示しない被係合部と係合した状態で、図示しないエアーシリンダ等の駆動源からの動力を受けて回転する。   In addition, the protrusions 22 and 23 at both ends of the shaft-like member 12 are rotatably supported by shaft support means (not shown) of the blanket cylinder cleaning device 1. The shaft-like member 12 rotates in response to power from a drive source such as an air cylinder (not shown) in a state where the engaging portion 24 is engaged with an engaged portion (not shown).

次に、上記清掃用シート巻取軸体５の作用等を説明する。   Next, the operation of the cleaning sheet take-up shaft 5 will be described.

図４に示すように、清掃用シート巻取軸体５を、軸状部材12の突起部30が筒状部材11の第２受部17に当接しかつ軸状部材12の軸本体部21の平面部分27が筒状部材11の開口部10に面して軸状部材12が開口部10から突出しない外形非円形状の軸径小状態にしてから、清掃用シートＳの先端部を筒状部材11の開口部10に臨んだ端部の角部分19に引っ掛けて位置決め固定する。   As shown in FIG. 4, the cleaning sheet take-up shaft 5 is arranged such that the protrusion 30 of the shaft-shaped member 12 abuts on the second receiving portion 17 of the tubular member 11 and the shaft main body 21 of the shaft-shaped member 12. After the flat portion 27 faces the opening 10 of the cylindrical member 11 and the shaft-shaped member 12 does not protrude from the opening 10, the outer diameter of the non-circular shape is reduced, and the front end of the cleaning sheet S is cylindrical. The member 11 is hooked on the corner portion 19 at the end facing the opening 10 to be positioned and fixed.

その後、図示しない駆動源からの動力で軸状部材12を筒状部材11に対して突起部30が第１受部16に当接するまで回転、すなわち例えば軸状部材12を筒状部材11に対して径大方向（図４中、反時計回り）に約１３０度回転させると、図５に示すように、清掃用シート巻取軸体５は、軸状部材12の突起部30が筒状部材11の第１受部16に当接しかつ軸状部材12の軸本体部21の円弧面部分26の一部が筒状部材11の開口部10から突出した外形略円形状の軸径大状態になる。   Thereafter, the shaft member 12 is rotated with respect to the cylindrical member 11 by power from a drive source (not shown) until the projection 30 abuts against the first receiving portion 16, that is, for example, the shaft member 12 is moved relative to the cylindrical member 11. When the sheet winding shaft 5 for cleaning is rotated about 130 degrees in the large diameter direction (counterclockwise in FIG. 4), the protruding portion 30 of the shaft-shaped member 12 has a cylindrical member as shown in FIG. 11 is in contact with the first receiving portion 16 and part of the arc surface portion 26 of the shaft main body portion 21 of the shaft-shaped member 12 projects from the opening portion 10 of the cylindrical member 11 into a large shaft diameter state. Become.

すなわち、軸状部材12の筒状部材11に対する回転により、清掃用シート巻取軸体５が軸径小状態から軸径大状態になり、清掃用シート巻取軸体５の軸径が増大し、その結果、清掃用シートＳにこの清掃用シートＳの長手方向に沿って所望の張力が作用する。   That is, the rotation of the shaft member 12 relative to the cylindrical member 11 changes the cleaning sheet winding shaft body 5 from the small shaft diameter state to the large shaft diameter state, thereby increasing the shaft diameter of the cleaning sheet winding shaft body 5. As a result, a desired tension acts on the cleaning sheet S along the longitudinal direction of the cleaning sheet S.

続いて、軸状部材12を筒状部材11に対してさらに回転させると、図６に示すように、軸状部材12の突起部30が筒状部材11の第１受部16を押すことによって筒状部材11が軸状部材12とともに回転し、その結果、軸径大状態の清掃用シート巻取軸体５の略円筒面状の外周面に、汚れた清掃用シートＳが順次巻き取られる。   Subsequently, when the shaft-shaped member 12 is further rotated with respect to the tubular member 11, the projection 30 of the shaft-shaped member 12 pushes the first receiving portion 16 of the tubular member 11 as shown in FIG. The cylindrical member 11 rotates together with the shaft-shaped member 12, and as a result, the dirty cleaning sheet S is sequentially wound on the substantially cylindrical outer peripheral surface of the cleaning sheet winding shaft 5 having a large shaft diameter. .

そして、図７に示すように所定量の清掃用シートＳが清掃用シート巻取軸体５の外周面にロール状に巻き取られた時点で、清掃用シート巻取軸体５を図示しない軸支持手段から外し、この清掃用シート巻取軸体５からロール状の清掃用シートＳを取り外す。   Then, as shown in FIG. 7, when a predetermined amount of the cleaning sheet S is wound around the outer peripheral surface of the cleaning sheet winding shaft 5 in a roll shape, the cleaning sheet winding shaft 5 is not illustrated. The roll-shaped cleaning sheet S is detached from the cleaning sheet take-up shaft 5 by removing it from the support means.

ロール状の清掃用シートＳを清掃用シート巻取軸体５から取り外す場合には、軸状部材12を筒状部材11に対して突起部30が第２受部17に当接するまで回転、すなわち例えば軸状部材12を筒状部材11に対して径小方向（図７中、時計回り）に約１３０度回転させる。   When removing the roll-shaped cleaning sheet S from the cleaning sheet take-up shaft 5, the shaft-shaped member 12 is rotated with respect to the tubular member 11 until the protrusion 30 contacts the second receiving portion 17, that is, For example, the shaft-shaped member 12 is rotated about 130 degrees in the small diameter direction (clockwise in FIG. 7) with respect to the cylindrical member 11.

すると、図８に示すように、清掃用シート巻取軸体５は、軸状部材12の突起部30が筒状部材11の第２受部17に当接しかつ軸状部材12の軸本体部21の平面部分27が筒状部材11の開口部10に面して軸状部材12が開口部10から突出しない外形非円形状の軸径小状態になり、清掃用シート巻取軸体５の軸径が減少する。その結果、ロール状の清掃用シートＳの一部が弛んだ状態となり、ロール状の清掃用シートＳを清掃用シート巻取軸体５から容易に取り外すことが可能となる。つまりロール状の清掃用シートＳの内周側から清掃用シート巻取軸体５を容易に引き抜くことが可能となる。   Then, as shown in FIG. 8, the cleaning sheet take-up shaft 5 has the protrusion 30 of the shaft-shaped member 12 abutting against the second receiving portion 17 of the tubular member 11 and the shaft main body of the shaft-shaped member 12. The flat portion 27 of 21 faces the opening 10 of the cylindrical member 11 and the shaft-shaped member 12 does not protrude from the opening 10 and is in a small outer diameter state. The shaft diameter decreases. As a result, a part of the roll-shaped cleaning sheet S is loosened, and the roll-shaped cleaning sheet S can be easily detached from the cleaning sheet take-up shaft 5. That is, the cleaning sheet take-up shaft 5 can be easily pulled out from the inner peripheral side of the roll-shaped cleaning sheet S.

このように清掃用シート巻取軸体５によれば、清掃用シートＳの巻き取り時には清掃用シート巻取軸体５が軸状部材12の筒状部材11に対する相対的な回転により軸状部材12の一部が開口部10から突出した軸径大状態になり、清掃用シートＳの取り外し時には清掃用シート巻取軸体５が軸状部材12の筒状部材11に対する相対的な回転により軸状部材12が開口部10から突出しない軸径小状態になるものであるから、構成が簡単であるばかりでなく、清掃用シートＳを清掃用シート巻取軸体５から容易に取り外すことができる。   Thus, according to the cleaning sheet take-up shaft 5, when the cleaning sheet S is taken up, the cleaning sheet take-up shaft 5 rotates relative to the tubular member 11 with respect to the tubular member 11. A part of 12 protrudes from the opening 10 to have a large shaft diameter, and when the cleaning sheet S is removed, the cleaning sheet take-up shaft 5 is rotated by relative rotation of the shaft member 12 with respect to the tubular member 11. Since the shaft member 12 is in a small shaft diameter state that does not protrude from the opening 10, not only is the configuration simple, but the cleaning sheet S can be easily detached from the cleaning sheet take-up shaft 5. .

なお、上記実施の形態では、軸状部材12の軸本体部21の外周面が円弧面部分26と平面部分27とにて構成された場合について説明したが、例えば平面部分27の代わりに軸状部材12の軸心側に向って凹状の湾曲面部やＶ状面部を有するようにしてもよい。   In the above-described embodiment, the case where the outer peripheral surface of the shaft main body portion 21 of the shaft-shaped member 12 is configured by the circular arc surface portion 26 and the flat surface portion 27 has been described. You may make it have a concave curved surface part and V-shaped surface part toward the axial center side of the member 12. FIG.
