Description

本発明は、オフセット印刷機のブランケット胴などの印刷機シリンダ表面を洗浄するシリンダ洗浄装置に係り、特に、シリンダ洗浄に必要なプレッシャパッドの形状に関する。 The present invention relates to a cylinder cleaning device that cleans the surface of a printing press cylinder such as a blanket cylinder of an offset printing press, and more particularly to the shape of a pressure pad necessary for cylinder cleaning .

従来、ブランケット胴や圧胴等を洗浄するシリンダ洗浄装置として、シリンダ表面に接離可能とした押圧部に、不織布からなる洗浄布をシリンダ表面に接して走行できるようにしておき、洗浄作業時に洗浄布をシリンダ表面に接触移動させることにより、押圧部のニップ圧とシリンダの回転を利用して表面汚れを払拭除去するところの装置が知られている。  Conventionally, as a cylinder cleaning device for cleaning blanket cylinders, impression cylinders, etc., a cleaning cloth made of non-woven fabric is allowed to run in contact with the cylinder surface at the pressing part that can contact and separate from the cylinder surface, and cleaning is performed during cleaning operations. There is known an apparatus that wipes and removes surface dirt using a nip pressure of a pressing portion and rotation of a cylinder by moving a cloth in contact with the cylinder surface.

この種のシリンダ洗浄装置においては、前記洗浄布を対象となっているシリンダの胴長方向に沿って均一に押庄するために、半円筒状に形成したゴムシートや、洗浄する際にエアでシートを膨張させるプレッシャパッドが知られており、シリンダ胴長方向に沿うパッド取付板にプレッシャパッドが固定されている。
しかしながら、このプレッシャパッドが均一な厚さであると、回転するシリンダのギャップに押圧部が当たって衝撃を受け、衝撃音や振動を発生してしまう問題があった。この問題を解消するために、押圧部材であるプレッシャパッド全体の厚さを均一にせず、シリンダと当接する部分である中央部の肉厚を薄くし、基部の肉厚を厚くしたプレッシャパッドが開発されている（特許文献１、特許文献２）。In this type of cylinder cleaning apparatus, a rubber sheet formed in a semi-cylindrical shape is used to uniformly press the cleaning cloth along the cylinder length direction of the target cylinder. A pressure pad for expanding a seat is known, and the pressure pad is fixed to a pad mounting plate along the cylinder body length direction.
However, if the pressure pad has a uniform thickness, there is a problem in that the pressing portion hits the gap of the rotating cylinder and receives an impact, generating an impact sound and vibration. In order to solve this problem, a pressure pad was developed that did not make the thickness of the entire pressure pad, which is a pressing member, uniform, but reduced the thickness of the central part, which is in contact with the cylinder, and increased the thickness of the base part. (Patent Document 1, Patent Document 2).

この様な、押圧部材であるゴムシート全体の厚さを均一にせずに、シリンダ表面と当接する部分である中央部を薄くし、基部を厚くしたプレッシャパッドは、回転するシリンダから受ける衝撃を中央部の薄肉部分で吸収し、剛性を増した基部の厚肉部分で押圧力を与えることで、衝撃音や振動を少なくするという優れた性能を有している。
しかし、シリンダの回転に伴なってプレッシャパッドの基部がシリンダの回転方向に引っ張られて、嵌着していたパッド取付板から部分的に持ち上げられ、プレッシャパッド表面に波打ち現象を生じ、払拭が不具合になることがある。A pressure pad with a thin base and a thick base that does not equalize the thickness of the entire rubber sheet, which is a pressing member, makes the center receive the impact received from the rotating cylinder. It has an excellent performance of reducing impact sound and vibration by absorbing at the thin part of the part and applying a pressing force at the thick part of the base with increased rigidity.
However, as the cylinder rotates, the base of the pressure pad is pulled in the direction of rotation of the cylinder, and is partially lifted from the pad mounting plate that has been fitted. May be.

さらに、特許文献１のように、両側を厚く中央を薄くした平板状のゴム板を馬蹄形に湾曲させてプレッシャパッドとして用いると、プレッシャパッドの両端部が上部方向に反り上がって鞍型形状となってしまい、この両端の反り上がりがシリンダ表面と先に接触して、プレッシャパッドの中央部分と接触できずに隙間を形成し、シリンダ面を均一に押圧できず、シリンダ表面に拭き残しを生起してしまう問題がある。 Furthermore, as in Patent Document 1, when a flat rubber plate with both sides thicker and thinner at the center is curved into a horseshoe shape and used as a pressure pad, both ends of the pressure pad are warped upward to form a saddle shape. As a result, the warping of both ends comes into contact with the cylinder surface first, forming a gap without being able to contact the center portion of the pressure pad, and the cylinder surface cannot be pressed uniformly, resulting in unwiping on the cylinder surface. There is a problem.

このようなシリンダ洗浄装置には、シリンダ表面の汚れを払拭した洗浄布を一定の長さで巻き取るように設定した定寸機構を備えた巻取りロールが設置してある。一定の長さをその都度巻き取るために、洗浄布の径を検知する検出ローラが巻取りロール一端の表面に押圧して配設されている。
しかしながら、巻取りロールの他端は押圧する部材はなく自由端になっているので、巻取りロールの一端に皺ができ、そのため、巻取り中に洗浄布の左右の径がかわりコーン状になって、裏面を洗浄布として使用できなくなってしまう問題がある。Such a cylinder cleaning apparatus is provided with a winding roll having a sizing mechanism that is set so as to wind up a cleaning cloth having wiped off the dirt on the cylinder surface with a certain length. In order to wind up a certain length each time, a detection roller for detecting the diameter of the cleaning cloth is pressed against the surface of one end of the winding roll.
However, the other end of the take-up roll has no pressing member and is a free end, so that one end of the take-up roll is wrinkled. As a result, the back surface cannot be used as a cleaning cloth.

また、洗浄布供給ロールと洗浄布巻取りロールを夫々シリンダ洗浄装置に装着するための軸受けが、シリンダ装置の左右のプレートに設けてある。この軸受けにロールの軸を装着させるためには、付勢されたスプリングの力に抗してホルダーカバーを移動し、軸を挿入すべき切り欠き部分を露出させねばならず、装着し難く手間が係る問題がある。   Also, bearings for mounting the cleaning cloth supply roll and the cleaning cloth take-up roll on the cylinder cleaning device are provided on the left and right plates of the cylinder device. In order to mount the roll shaft on this bearing, the holder cover must be moved against the force of the biased spring to expose the notch where the shaft is to be inserted. There is such a problem.

更に、シリンダ表面の汚れを洗浄する洗浄布には予め洗浄液を含浸させた、いわゆるウェット布が用いられるが、含浸した洗浄液がシリンダ表面に残り、次に開始する印刷インキをはじくために、シリンダ表面を布で拭き取らなければならず手間が係ると共に、洗浄布が石油資材を用いるために洗浄コストが高いという問題がある。
特許第３２７００1８号公報 特開平１１-３００９４２号公報 In addition, a so-called wet cloth impregnated with a cleaning liquid is used as a cleaning cloth for cleaning dirt on the cylinder surface, but the impregnated cleaning liquid remains on the cylinder surface, and in order to repel the printing ink to be started next, the cylinder surface Has to be wiped off with a cloth, and there is a problem that the cleaning cost is high because the cleaning cloth uses petroleum materials.

以下、本発明の実施の形態を図面に基づき説明する。
図１〜図３に示す第１の実施形態であるシリンダ洗浄装置１は、洗浄対象であるブランケット胴２に対向して配置されており、シリンダ洗浄装置１は着脱可能で洗浄布のロールが装着される一対のプレート３と、該プレート３の外側に印刷機の枠に固設しているフレーム４で骨組みを構成し、一方のフレーム４に押圧手段源であるエアシリンダ５が設置されている。
このエアシリンダ５によりシリンダ洗浄装置１は回転軸６を中心に回動されて、ブランケット胴２に接触と離脱をさせる働きをしている。Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The cylinder cleaning device 1 according to the first embodiment shown in FIGS. 1 to 3 is arranged to face the blanket cylinder 2 to be cleaned, and the cylinder cleaning device 1 is detachable and is attached with a roll of cleaning cloth. A pair of plates 3 and a frame 4 fixed to the frame of the printing machine are formed on the outside of the plate 3 to form a framework, and one frame 4 is provided with an air cylinder 5 as a pressing means source. .
The cylinder cleaning device 1 is rotated about the rotating shaft 6 by the air cylinder 5 and serves to bring the blanket cylinder 2 into contact and separation.

押圧部はブランケット胴２に対向して設けられ、図３に示すように、押圧部材であるプレッシャパッド８が取り付けられるパッド取付板９と、パッド取付板９の両端に洗浄布１３をガイドするためのガイド部１０ａ、１０ｂとで構成されている。   The pressing portion is provided opposite to the blanket cylinder 2, and as shown in FIG. 3, a pad mounting plate 9 to which a pressure pad 8 as a pressing member is mounted, and a cleaning cloth 13 to guide both ends of the pad mounting plate 9. The guide portions 10a and 10b.

プレート３上のパッド取付板９の後方には、洗浄布供給ロール１１と洗浄布巻取ロール１２とが配置され、洗浄布１３は布供給ロール１１から繰り出され、図中ガイド部１０ａからプレッシャパッド８を経由して、ガイド部１０ｂと洗浄布ガイドローラ１４を経て後方の洗浄布巻取ロール１２にて巻取られるようになっている。
洗浄布１３の巻取は、洗浄布供給ロール１１に制動を掛けることで、洗浄布巻取ロール１２を間歇的に回転駆動することにより行われる。 A cleaning cloth supply roll 11 and a cleaning cloth take-up roll 12 are arranged behind the pad mounting plate 9 on the plate 3, and the cleaning cloth 13 is fed out from the cloth supply roll 11, and the pressure pad 8 from the guide portion 10 a in the drawing. , Via the guide section 10b and the cleaning cloth guide roller 14, the cleaning cloth take-up roll 12 on the rear side winds up.
The cleaning cloth 13 is wound by intermittently driving the cleaning cloth winding roll 12 by braking the cleaning cloth supply roll 11 .

なお、本実施形態において、予め洗浄液が含浸された洗浄布１３を用いているが、洗浄液が含浸されていないドライな洗浄布１３を使用してもよい。この場合は、プレッシャパッド８の上流側に配置した洗浄液供給ノズル７から洗浄布１３に対して洗浄液を適宜噴出し湿潤状態にする。 In this embodiment, the cleaning cloth 13 impregnated with the cleaning liquid in advance is used, but a dry cleaning cloth 13 that is not impregnated with the cleaning liquid may be used. In this case, the cleaning liquid is appropriately ejected from the cleaning liquid supply nozzle 7 disposed on the upstream side of the pressure pad 8 to the cleaning cloth 13 to be in a wet state .

押圧部材であるプレッシャパッド８は、弾性を有し耐薬品性を有する例えば、ニトリルブタジェンゴムからなるゴムシートを、断面形状が楕円形をした半円筒状に成形したものが好ましい。   The pressure pad 8 as a pressing member is preferably a rubber sheet made of, for example, nitrile butadiene rubber having elasticity and chemical resistance, and formed into a semi-cylindrical shape having an elliptical cross-sectional shape.

図３に示すように、半円筒状に成形されたプレッシャパッド８は、半円筒状の両端部分の基部１５の肉厚を厚くし、洗浄布１３を押圧する中央部分の凸部の肉厚を薄くしている。例えば、基部１５の厚さｂ１は６．５〜７．５ｍｍ、好ましくは７ｍｍであり、中央部１６の厚さａは２．５〜３．５ｍｍ、好ましくは３ｍｍである。このように、基部１５の肉厚を厚くし、中央部１６の肉厚を薄くしたことで、後述するように基部１５の剛性が増してシリンダ洗浄性能を高めることが出来る。   As shown in FIG. 3, the pressure pad 8 formed in a semi-cylindrical shape increases the thickness of the base portion 15 at both end portions of the semi-cylindrical shape, and the thickness of the convex portion at the central portion that presses the cleaning cloth 13. It is thin. For example, the thickness b1 of the base portion 15 is 6.5 to 7.5 mm, preferably 7 mm, and the thickness a of the central portion 16 is 2.5 to 3.5 mm, preferably 3 mm. As described above, by increasing the thickness of the base portion 15 and reducing the thickness of the central portion 16, the rigidity of the base portion 15 can be increased and cylinder cleaning performance can be improved as will be described later.

プレッシャパッド８の夫々の基部１５には、内側に向けて互いに水平即ち図３における横方向に対向した係止部１７が設けられ、この係止部１７は細くなった頸部１８と、頸部１８に連続する突起部１９とからなり、この突起部１９は係止部１７の先端で上方に向け突出している。   Each base portion 15 of the pressure pad 8 is provided with a locking portion 17 that faces each other in the horizontal direction, that is, in the lateral direction in FIG. 3, and this locking portion 17 includes a narrowed neck portion 18 and a neck portion. 18, and the protrusion 19 protrudes upward at the tip of the locking portion 17.

また、図３に示すように、基部１５の外面１５１は垂直に形成され、センターラインＣＬに沿って胴長方向に伸びるセンター面に平行とされている。
内面１５２は、後記のパッド押さえバー２０の高さより若干低くなる中央部１６と基部１５との境界から、係止部１７にかけて、下方に行くに従い内側に湾曲又は直線状に傾いて傾斜面が形成され、基部１５は下方に行くに従って内側に湾曲又は直線状に傾いて傾斜面が形成されるから、基部１５は下方に行くに従って肉厚になる。
基部１５の底面から境界までの高さは、 １２．５〜１３.５ｍｍ、好ましくは１３ｍｍである。As shown in FIG. 3, the outer surface 151 of the base portion 15 is formed vertically and is parallel to the center surface extending in the body length direction along the center line CL.
The inner surface 152 is inclined inwardly or linearly as it goes downward from the boundary between the center portion 16 and the base portion 15, which is slightly lower than the height of the pad pressing bar 20, which will be described later, to the locking portion 17. The base portion 15 is curved or linearly inclined to form an inclined surface as it goes downward, so that the base portion 15 becomes thicker as it goes downward.
The height from the bottom surface of the base 15 to the boundary is 12.5 to 13.5 mm, preferably 13 mm.

このプレッシャパッド８は、パッド押さえバー２０とパッド取付板９との間に配設されることにより固定される。
パッド押さえバー２０は胴長方向に伸び、その断面が略Ｔ字状の金属部材でなり、ブランケット胴２に近い上部位２1と遠い下部位２３とで略Ｔ字状を形成し、平面となっている頂面２０１と、中央部１６内面の曲面に沿って下方に行くに従い外側に傾く外向傾斜面２０２と、基部１５の内面１５２に沿って内側に傾く内向傾斜面２０３とを有する。The pressure pad 8 is fixed by being disposed between the pad pressing bar 20 and the pad mounting plate 9.
The pad presser bar 20 extends in the body length direction, and the cross section thereof is a metal member having a substantially T-shape. The upper part 21 close to the blanket cylinder 2 and the lower part 23 far away form a substantially T-shape. A top surface 201, an outwardly inclined surface 202 that inclines outward along the curved surface of the inner surface of the central portion 16, and an inwardly inclined surface 203 that inwardly inclines along the inner surface 152 of the base portion 15.

上部位２１の頂面２０１の幅ｃ（図４参照）は、２３〜２５ｍｍ、好ましくは２４ｍｍであり、上部位２１の最大幅部 （傾斜面２０２と２０３との交差点）の幅ｄは２５.５〜２７.５ｍｍ、好ましくは２６.５ｍｍである。   The width c (see FIG. 4) of the top surface 201 of the upper portion 21 is 23 to 25 mm, preferably 24 mm, and the width d of the maximum width portion (intersection of the inclined surfaces 202 and 203) of the upper portion 21 is 25. It is 5 to 27.5 mm, preferably 26.5 mm.

上部位２１の高さはプレッシャパッド８の係止部１７の下面１７１、即ち底面から中央部１６内側の高さ（２２〜２６ｍｍ）の２分の１から３分の２の範囲で成形され、上部位２１の下面は突起部１９が挿入される溝２２が画成されている。頸部１８、突起部１９、溝２２の各幅は１．５〜２．５ｍｍ、好ましくは２ｍｍであり、両突起部１９の間隔は１３.５〜１５.５ｍｍ、好ましくは １４.５ｍｍである。   The height of the upper portion 21 is formed in a range from one half to two thirds of the lower surface 171 of the locking portion 17 of the pressure pad 8, that is, the height (22 to 26 mm) inside the central portion 16 from the bottom surface, A groove 22 into which the protruding portion 19 is inserted is defined on the lower surface of the upper portion 21. The widths of the neck 18, the protrusion 19, and the groove 22 are 1.5 to 2.5 mm, preferably 2 mm, and the distance between both protrusions 19 is 13.5 to 15.5 mm, preferably 14.5 mm. .

パッド押さえバー２０の下部位２３には、ブランケット胴２の胴長方向に適宜複数の箇所にねじ溝２４が螺設されている。   In the lower part 23 of the pad pressing bar 20, screw grooves 24 are screwed at a plurality of positions as appropriate in the body length direction of the blanket cylinder 2.

パッド取付板９は両端に洗浄布１３をガイドするためのガイド部１０ａ、１０ｂが設けられたアルミ板等の金属製で成形されており、上面にプレッシャパッド８の基部１５が挿入される凹部２５と、この凹部２５内にパッド押さえバー２０の下部位２３が挿入される第２の凹部２６が胴長方向に削設されている。この第２凹部２６とパッド押さえバー２０の底面の隙間が、プレッシャパッド８の基部１５を押圧する締め代δとなる。   The pad mounting plate 9 is made of metal such as an aluminum plate provided with guide portions 10a and 10b for guiding the cleaning cloth 13 at both ends, and a concave portion 25 into which the base portion 15 of the pressure pad 8 is inserted on the upper surface. And the 2nd recessed part 26 by which the lower part 23 of the pad pressing bar 20 is inserted in this recessed part 25 is cut in the trunk | drum length direction. A gap between the second recess 26 and the bottom surface of the pad pressing bar 20 becomes a fastening allowance δ for pressing the base portion 15 of the pressure pad 8.

凹部２５の深さは、プレッシャパッド８の基部１５がパッド取付板９に固定された際、パッド押さえバー２０の上部位２１の側面によって凹部２５の内壁に十分押圧されるように深く切削している。また、第２凹部２６にはパッド押さえバー２０をボルト２７によって固定するための孔２８が穿設されている。   When the base 15 of the pressure pad 8 is fixed to the pad mounting plate 9, the depth of the recess 25 is deeply cut so that the side surface of the upper portion 21 of the pad pressing bar 20 is sufficiently pressed against the inner wall of the recess 25. Yes. The second recess 26 has a hole 28 for fixing the pad pressing bar 20 with a bolt 27.

上記構成による作用について、次に説明する。
まず、半円筒状に成形されている弾性材のプレッシャパッド８の突起部１９をパッド押さえバー２０の溝２２に嵌入して、プレッシャパッド８とパッド押さえバー２０とを組み付け、次にパッド押さえバー２０の下部位２３を、パッド取付板９の第２凹部２６内に差し込むとともに、プレッシャパッド８の基部１５も凹部２５内に挿入する。 The operation of the above configuration will be described next.
First, the protruding portion 19 of the pressure pad 8 made of an elastic material formed in a semi-cylindrical shape is fitted into the groove 22 of the pad pressing bar 20, the pressure pad 8 and the pad pressing bar 20 are assembled, and then the pad pressing bar The lower portion 23 of 20 is inserted into the second recess 26 of the pad mounting plate 9, and the base 15 of the pressure pad 8 is also inserted into the recess 25.

そして、パッド取付板９の下面から、ボルト２７をパッド押さえバー２０のネジ溝２４に螺着して締め代δ分増し締めすると、パッド押さえバー２０の溝２２内に係止部１７の頸部１８と突起部１９とが食い込む。この時、パッド押さえバー２０の上部位２１の傾斜面 ２０３は、基部１５に設けた傾斜面１５２と当接しながら下方へと強制的に下げられ、基部１５の肉厚部分を凹部２５の側壁に対し外側に向けて押圧して、プレッシャパッド８をパッド取付板９に強固に固定する。   Then, when the bolt 27 is screwed into the screw groove 24 of the pad pressing bar 20 from the lower surface of the pad mounting plate 9 and tightened by a tightening allowance δ, the neck of the locking portion 17 is inserted into the groove 22 of the pad pressing bar 20. 18 and the protrusion 19 bite in. At this time, the inclined surface 203 of the upper portion 21 of the pad pressing bar 20 is forcibly lowered while abutting the inclined surface 152 provided on the base portion 15, and the thick portion of the base portion 15 is moved to the side wall of the recess 25. The pressure pad 8 is firmly fixed to the pad mounting plate 9 by pressing outward.

シリンダ洗浄装置１は、回転軸６を中心にエアシリンダ５の作動によって回動され、ブランケット胴２に向けて所定量前進移動し、プレッシャパッド８を介して、洗浄布供給ロール １１から供給された洗浄布１３をブランケット胴２に所定の押圧力で接触させて払拭洗浄を行い、図示しない定寸送り装置により、一定量の洗浄布１３が洗浄布ガイドローラ１４を経由して布巻取ロール１２に巻き取られる。
また、払拭洗浄後は、シリンダ洗浄装置１が後退させられブランケット胴２と離れて洗浄を終了する。これを繰り返すことにより払拭洗浄が行われる。The cylinder cleaning device 1 is rotated by the operation of the air cylinder 5 around the rotating shaft 6, moves forward by a predetermined amount toward the blanket cylinder 2, and is supplied from the cleaning cloth supply roll 11 via the pressure pad 8. The cleaning cloth 13 is brought into contact with the blanket cylinder 2 with a predetermined pressing force for wiping and cleaning, and a fixed amount of the cleaning cloth 13 is passed through the cleaning cloth guide roller 14 to the cloth take-up roll 12 by a sizing feeding device (not shown). It is wound up.
Further, after the wiping cleaning, the cylinder cleaning device 1 is moved backward to leave the blanket cylinder 2 and the cleaning is finished. Wiping cleaning is performed by repeating this.

払拭洗浄時のプレッシャパッド８は、基部１５の下方に行くにつれ肉厚が増していくので、外部からの圧力に対して剛性が高くなる上、係止部１７の突起部１９がパッド押さえバー２０の溝２２に係止され、更に上部位２1の内向傾斜側面２０３が基部１５を凹部２５側壁に強く押し付けている為、ブランケット胴２の回転に伴うプレッシャパッド８の基部１５は動かず、中央部１６のみがブランケット胴２の回転に伴い上下動に変形することになる。   Since the pressure pad 8 at the time of wiping and cleaning increases in thickness as it goes below the base portion 15, the pressure pad 8 becomes rigid against an external pressure, and the protrusion 19 of the locking portion 17 has a pad holding bar 20. Since the inwardly inclined side surface 203 of the upper portion 21 strongly presses the base portion 15 against the side wall of the recess 25, the base portion 15 of the pressure pad 8 does not move as the blanket cylinder 2 rotates, and the central portion Only 16 is deformed up and down as the blanket cylinder 2 rotates.

ブランケット胴２のクランプ機構による凹凸等で、プレッシャパッド６の中央部１６にシリンダ回転に伴う持ち去り力や衝撃が加えられても、前述のように剛性を増しパッド取付板９に固定された基部１５は、回転に伴って持ち上げられるようなことはなく安定しているので、中央部１６は単にブランケット胴２の動きにつれて上下に動くだけで、ブランケット胴２の胴長方向において波打ち現象を起こさず、また、洗浄布１３に接触する中央部１６の位置が安定して、ニップ圧とニップ幅を一定にして払拭洗浄能力を向上することができる。   Even if a force or impact caused by the rotation of the cylinder is applied to the central portion 16 of the pressure pad 6 due to unevenness caused by the clamping mechanism of the blanket cylinder 2, the base portion is increased in rigidity and fixed to the pad mounting plate 9 as described above. 15 is stable because it is not lifted with rotation, and the central portion 16 simply moves up and down as the blanket cylinder 2 moves, and does not cause undulation in the length direction of the blanket cylinder 2. In addition, the position of the central portion 16 in contact with the cleaning cloth 13 can be stabilized, and the wiping and cleaning performance can be improved by making the nip pressure and the nip width constant.

次にシリンダ洗浄装置の第２の実施の形態を図４により説明するが、第１の形態と同じ作用を行う部位には同じ番号を付して詳細な説明は省略し、異なる箇所を詳細に説明する。   Next, a second embodiment of the cylinder cleaning device will be described with reference to FIG. 4, but the same reference numerals are given to parts that perform the same operation as the first embodiment, and detailed description will be omitted, and different parts will be described in detail. explain.

半円筒状に成形した弾性材のプレッシャパッド３０は、基部３１と中央部３２とで構成され、基部３１の肉厚は凸面先端部３２の肉厚よりも厚くなっている。基部３１の厚さｂ２は５．５〜７．５ｍｍ、好ましくは６. ５ｍｍであり、中央部３２の肉厚は図３と同じである。   The pressure pad 30 made of an elastic material formed in a semi-cylindrical shape includes a base portion 31 and a central portion 32, and the thickness of the base portion 31 is thicker than the thickness of the convex tip portion 32. The thickness b2 of the base portion 31 is 5.5 to 7.5 mm, preferably 6.5 mm, and the thickness of the central portion 32 is the same as that in FIG.

夫々の基部３１には内側に向けて互いに水平に対向した係止部３３が設けられ、この係止部３３は細くなった頸部３４と突起部３５とを有し、この突起部３５は係止部３３の先端で上方に向け突出している。   Each base portion 31 is provided with a locking portion 33 horizontally facing each other inward, and this locking portion 33 has a narrowed neck portion 34 and a protruding portion 35, and the protruding portion 35 is engaged. Projecting upward at the tip of the stop 33.

基部３１の外面３１１は垂直となっているが、内面は中央部３２と基部３１との境界部から係止部３３にかけて内側に傾斜する内向傾斜面３２１となった膨出部と、その膨出部下方から外面３１１と平行に垂直とされた垂直面３２２とからなっている。   The outer surface 311 of the base portion 31 is vertical, but the inner surface is a bulging portion that is an inwardly inclined surface 321 that is inclined inwardly from the boundary portion between the central portion 32 and the base portion 31 to the locking portion 33, and the bulging portion. It consists of a vertical surface 322 that is perpendicular to the outer surface 311 in parallel to the lower part.

パッド押さえバー２０の上部位２１の内向傾斜面（図３の２０３）は、プレッシャパッド３０をパッド取付板９に締め代δ分組み付けられる際に、基部３１に設けた内向傾斜面３２１と当接かつ押圧しながら下方へと強制的に下げられ、その結果、基部３１の肉厚部分を凹部２５の側壁に対し外側に向けて押圧していくことは第１の実施形態と同様で、基部３１の剛性が高くなる上、係止部３３の突起部３５がパッド押さえバー２０の溝２２に係止され、更に上部位２１の傾斜側面２０３が基部３１を凹部２５側壁に強く押し付けている為、ブランケット胴２の回転に伴なう基部３１の動きはなく、中央部３２のみが上下動に変形することになる。   The inwardly inclined surface (203 in FIG. 3) of the upper portion 21 of the pad pressing bar 20 is in contact with the inwardly inclined surface 321 provided in the base portion 31 when the pressure pad 30 is assembled to the pad mounting plate 9 by the tightening allowance δ. In addition, it is forcibly lowered downward while pressing, and as a result, the thick portion of the base 31 is pressed outward against the side wall of the recess 25 as in the first embodiment. Since the protrusion 35 of the locking portion 33 is locked to the groove 22 of the pad pressing bar 20 and the inclined side surface 203 of the upper portion 21 strongly presses the base 31 against the side wall of the recess 25. There is no movement of the base portion 31 accompanying the rotation of the blanket cylinder 2, and only the central portion 32 is deformed to move up and down.

図４における基部３１の内面の一部を垂直面とすることにより、プレッシャパッド３０の製造が容易になる。なお、図４において、基部３１は押さえバー２０が押し下げられる前の状態を示し、また押さえバー２０は押し下げた状態を示しており、両者の輪郭線が交差している。   By making a part of the inner surface of the base 31 in FIG. 4 a vertical surface, the pressure pad 30 can be easily manufactured. In FIG. 4, the base 31 shows a state before the presser bar 20 is pushed down, and the presser bar 20 shows a pushed down state, and the contour lines of the two intersect.

第３の実施の形態を図５により説明するが、第１の形態と同じ作用を行う部位には同じ番号を付して詳細な説明は省略し、異なる箇所を詳細に説明する。   Although the third embodiment will be described with reference to FIG. 5, the same reference numerals are assigned to the same parts as those in the first embodiment, and detailed description thereof will be omitted, and different parts will be described in detail.

半円筒状に成形した弾性材のプレッシャパッド４０は、これまでと同様に、基部４１と中央部４２とで構成され、基部４１の肉厚は中央部４２の肉厚よりも厚くなっている。夫々の基部４１には内側に向けて互いに水平に対向した係止部４３が設けられ、この係止部４３は細くなった頸部４４と突起部４５とを有し、この突起部４５は係止部４３の先端で上方にむけ突出している。   The pressure pad 40 made of an elastic material formed in a semi-cylindrical shape is composed of a base portion 41 and a central portion 42 as before, and the thickness of the base portion 41 is thicker than the thickness of the central portion 42. Each base portion 41 is provided with a locking portion 43 that is horizontally opposed to each other inward, and this locking portion 43 has a narrowed neck portion 44 and a protruding portion 45, and this protruding portion 45 is engaged. It protrudes upward at the tip of the stop 43.

基部４１の外面４１１は、係止部４３にかけて下方に行くに従い内方に向けて傾いた内向傾斜面が形成され、尻つぼみ状態となっている。また、パッド取付板９に切削した凹部４６の内側壁４６１は、内側に向けて傾いた内向傾斜面が形成されている。   The outer surface 411 of the base 41 is formed with an inwardly inclined surface that is inclined inward as it goes downward toward the locking portion 43, and is in a bottom bud state. Further, the inner wall 461 of the recess 46 cut into the pad mounting plate 9 is formed with an inwardly inclined surface inclined inward.

プレッシャパッド４０の基部４１の内面４１２は湾曲面に形成され、その下端部は垂直となり、また、パッド押さえバー２０の上部位２１の側面２１４は、前記内面４１２と同様の湾曲面とされており、両者の形状が単純化されている。   The inner surface 412 of the base 41 of the pressure pad 40 is formed in a curved surface, the lower end thereof is vertical, and the side surface 214 of the upper portion 21 of the pad pressing bar 20 is a curved surface similar to the inner surface 412. Both shapes are simplified.

第３の実施形態においても、プレッシャパッド４０の基部４１は、パッド押さえバー２０の上部材２１の溝２２に突起部４５が挿入されて幅方向への移動が抑制され、凹部４６の傾斜面４６１とプレッシャパッド４０の外側の内向傾斜面４１１とが当接しながらボルト２７で締め代δ分が螺着されるので、ブランケット胴２の回転がプレッシャパッド４０に加わっても、基部４１の凹部４６内壁への押圧力と剛性増加により、プレッシャパッド４０の基部４１をパッド取付板９から持ち上げさせることはない。   Also in the third embodiment, the base portion 41 of the pressure pad 40 has the protrusion 45 inserted into the groove 22 of the upper member 21 of the pad pressing bar 20 to suppress the movement in the width direction, and the inclined surface 461 of the recess 46. And the inwardly inclined surface 411 on the outer side of the pressure pad 40 are in contact with each other, and the tightening allowance δ is screwed by the bolt 27. Therefore, even if rotation of the blanket cylinder 2 is applied to the pressure pad 40, the inner wall of the recess 46 of the base 41 The base 41 of the pressure pad 40 is not lifted from the pad mounting plate 9 by the pressing force and the rigidity increase.

第４の実施の形態を図６により説明するが、第１の形態と同じ作用を行う部位には同じ番号を付して詳細な説明は省略し、異なる箇所を詳細に説明する。   Although the fourth embodiment will be described with reference to FIG. 6, parts that perform the same operations as those of the first embodiment are denoted by the same reference numerals, detailed description thereof is omitted, and different parts will be described in detail.

断面を半円筒状に成形した弾性材のプレッシャパッド５０は、中央部５１と基部５２とで構成され、これまでと同様に、基部５２の肉厚は中央部５１の肉厚よりも厚くなっている。夫々の基部５２の外面５２１は垂直面を形成していると共に、基部５２の内面は内側に向け係止部５３が設けられ、この係止部５３は基部５２からパッド取付板５６の凹部５９のセンターラインＣＬに向けて下方に傾斜する内向傾斜面５３１を有している。
この内向傾斜面５３１のセンターラインＣＬに対する傾斜角は３０〜６０°、好ましくは４５°である。The pressure pad 50 made of an elastic material having a semi-cylindrical cross section is composed of a central part 51 and a base part 52, and the thickness of the base part 52 is thicker than the thickness of the central part 51 as before. Yes. The outer surface 521 of each base portion 52 forms a vertical surface, and the inner surface of the base portion 52 is provided with a locking portion 53 directed inward. The locking portion 53 is formed from the base portion 52 to the recess 59 of the pad mounting plate 56. An inwardly inclined surface 531 that inclines downward toward the center line CL is provided.
The inclination angle of the inwardly inclined surface 531 with respect to the center line CL is 30 to 60 °, preferably 45 °.

パッド押さえバー５５は断面が逆台形をした金属製で、その下部側面に内方に向け傾斜した内向傾斜面５６が形成され、この内向傾斜面５６の傾斜角もプレッシャパッド５０の内向傾斜面５３１と同様の傾斜角を有し、パッド押さえバー５５の内向傾斜面５６と基部５２の内向傾斜面５３１とがプレッシャパッド５０の幅方向の移動を抑制する。
押圧傾斜面とされる内向傾斜面５６の高さは、パッド押さえバー５５の高さの３分の１〜３分の２となっている。The pad pressing bar 55 is made of metal having a reverse trapezoidal cross section, and an inwardly inclined surface 56 inclined inward is formed on a lower side surface thereof. The inclination angle of the inwardly inclined surface 56 is also an inwardly inclined surface 531 of the pressure pad 50. The inwardly inclined surface 56 of the pad pressing bar 55 and the inwardly inclined surface 531 of the base 52 suppress the movement of the pressure pad 50 in the width direction.
The height of the inwardly inclined surface 56, which is the pressing inclined surface, is 1/3 to 1/3 of the height of the pad pressing bar 55.

パッド押さえバー５５にはボルト５４が螺合するねじ溝６０が螺設され、また、パッド押さえバー５５の上部側面は、中央部５１の内面の湾曲面に沿う湾曲面５７が形成されており、該湾曲面５７はプレッシャパッド５０の中央部５１側の変形防止壁として機能する。   The pad pressing bar 55 is screwed with a thread groove 60 into which the bolt 54 is screwed, and the upper side surface of the pad pressing bar 55 is formed with a curved surface 57 along the curved surface of the inner surface of the central portion 51. The curved surface 57 functions as a deformation preventing wall on the central portion 51 side of the pressure pad 50.

ブランケット胴２と対向し胴長方向に伸びたパッド取付板５８には、プレッシャパッド５０が挿入される凹部５９が削設されているが、前記実施形態における第２凹部がなく、形状が単純化されている。また、パッド押さえバー５５の形状も単純化されている。   The pad mounting plate 58 facing the blanket cylinder 2 and extending in the cylinder length direction is provided with a recess 59 into which the pressure pad 50 is inserted, but there is no second recess in the embodiment, and the shape is simplified. Has been. Further, the shape of the pad pressing bar 55 is also simplified.

プレッシャパッド５０の基部傾斜面５３１とパッド押さえバー５５の内向傾斜面５６とを当接させ、プレッシャパッド５５をパッド取付板５８の凹部５９内に挿入し、パッド押さえバー５５をパッド取付板５８にボルト５４で締め代δ分を締めて固定する際に、パッド押さえバー５５の締め付け力は内向傾斜面５６から基部傾斜面５３１に斜め方向即ち図中の矢印方向に伝わり、傾斜面５３１は図中の破線で示す傾斜面５３２に変位し、プレッシャパッド５０の基部５２をパッド取付板５８の凹部５９の底面及び内壁に押圧する。
従って、第１実施形態と同様に、ブランケット胴２の回転に伴うプレッシャパッド５０の基部５２の変形を抑制することができる。 The base inclined surface 531 of the pressure pad 50 and the inwardly inclined surface 56 of the pad pressing bar 55 are brought into contact with each other, the pressure pad 55 is inserted into the recess 59 of the pad mounting plate 58, and the pad pressing bar 55 is attached to the pad mounting plate 58. When the bolt 54 is fixed by tightening the tightening allowance δ, the tightening force of the pad pressing bar 55 is transmitted from the inwardly inclined surface 56 to the base inclined surface 531 in an oblique direction, that is, in the direction of the arrow in the figure, and the inclined surface 531 is shown in the figure. The base 52 of the pressure pad 50 is pressed against the bottom surface and the inner wall of the recess 59 of the pad mounting plate 58.
Therefore, similarly to the first embodiment, the deformation of the base 52 of the pressure pad 50 accompanying the rotation of the blanket cylinder 2 can be suppressed.

なお、プレッシャパッドの基部の外面を底面に向けて外方に傾斜させることで幅方向に肉厚を増加させた外向傾斜面にすると共に、パッド取付板に削設した第１の凹部の外壁を、プレッシャパッドの外向傾斜面と同じく外方に傾斜させた外向傾斜面を形成してもよい。   In addition, the outer surface of the base of the pressure pad is inclined outwardly toward the bottom surface to form an outwardly inclined surface whose thickness is increased in the width direction, and the outer wall of the first recess cut in the pad mounting plate is provided. An outwardly inclined surface that is inclined outward may be formed in the same manner as the outwardly inclined surface of the pressure pad.
