【０００１】0001
本考案は圧胴を回転させながらその周面を洗浄する印刷機の圧胴洗浄装置に関 するものである。 This invention relates to an impression cylinder cleaning device for a printing press that cleans the surrounding surface of the impression cylinder while rotating it. It is something to do.
【０００２】0002
印刷作業の終了時には、圧胴の周面がインキや紙粉などで汚れているので、こ れを洗浄する必要があり、このために印刷機の印刷ユニットには従来、以下その 概要を説明する圧胴洗浄装置が付設されている。すなわち、従来におけるこの種 の圧胴洗浄装置は、圧胴の周面に近接する箇所に設けられており、左右の装置フ レームと、この装置フレームに回転自在に軸支されて圧胴の軸線方向に延びる巻 き戻しローラおよび巻き取りローラと、これら両ローラの間に位置して装置フレ ーム側に支持された弾性材製のパッドとを備えている。そして、巻き戻しローラ には、これとほゞ同幅で長い帯状に形成された帯状体としての例えば洗浄布が巻 き付けられており、この洗浄布は巻き戻されてパッドの表面に添接したのち、巻 き取りローラに巻き付けられている。 At the end of the printing process, the circumferential surface of the impression cylinder will be dirty with ink and paper dust, so please do not For this purpose, the printing units of printing presses have traditionally been equipped with An impression cylinder cleaning device, which will be explained briefly, is attached. In other words, this type of The impression cylinder cleaning device is installed near the circumferential surface of the impression cylinder, and the a frame, and a winding rotatably supported by the device frame and extending in the axial direction of the impression cylinder. The return roller, the take-up roller, and the device frame located between these rollers. and a pad made of elastic material supported on the arm side. And the rewind roller For example, a cleaning cloth is wrapped around the belt, which is formed into a long belt with approximately the same width. The cleaning cloth is rewound and attached to the surface of the pad, and then unwound. Wrapped around the scraping roller.
【０００３】 そして、洗浄作業に際しては、印刷作業中に圧胴周面から退去していた装置全 体を移動させて洗浄布を介しパッドを圧胴の周面に対接させ、圧胴を回転させな がら、巻き取りローラを回転させると、洗浄布は巻き戻しローラから巻き戻され て巻き取りローラに巻き取られ、この洗浄布は走行途中でパッドによって圧胴周 面に押圧されるので、圧胴周面に付着した異物は洗浄布で拭き取られ、異物の付 着により汚れた洗浄布が巻き取られるとともに、パッドには巻き戻しローラから 巻き戻された新たな洗浄布が供給される。この場合、従来の装置では一般に、洗 浄布用の巻き取りローラが、エアシリンダによりセグメントギアとピニオンとを 介し間欠回転している。さらに、この種の圧胴洗浄装置においては、圧胴の周面 から突出しているくわえ爪装置と前記パッドとが干渉しないように、圧胴の端部 にカムを設け、くわえ爪装置が通過するときだけこのカムで洗浄装置全体をくわ え爪装置から逃がすようにした爪かわし機構が付設されている。0003 During the cleaning process, all the equipment that had been removed from the impression cylinder surface during the printing process should be cleaned. Move your body so that the pad is in contact with the circumferential surface of the impression cylinder through the cleaning cloth, and do not rotate the impression cylinder. However, when the take-up roller is rotated, the cleaning cloth is rewound from the rewind roller. The cleaning cloth is wound around the impression cylinder by a pad during its travel. Since it is pressed against the surface of the impression cylinder, foreign matter adhering to the surface of the impression cylinder is wiped off with a cleaning cloth, At the same time, the cleaning cloth that has become dirty due to wear and tear is wound up, and the pad is also A new rewound cleaning cloth is supplied. In this case, conventional equipment typically The take-up roller for clean cloth is connected to the segment gear and pinion by an air cylinder. It is rotating intermittently. Furthermore, in this type of impression cylinder cleaning device, the peripheral surface of the impression cylinder is The end of the impression cylinder should be A cam is installed in the cam, and the cam grips the entire cleaning device only when the gripper device passes. A claw dodging mechanism is attached to allow the claw to escape from the claw device.
【０００４】0004
しかしながら、このような従来の圧胴洗浄装置においては、上記のように洗浄 布用の巻き取りローラがエアシリンダで駆動されて間欠回転しているので、巻き 取り専用のエアシリンダを設けなければならないことにより設備費が嵩むし、ま た、洗浄作業中、エアシリンダのピストンロッドを絶えず往復動させなければな らないので、多量のエアを消費して運転経費が嵩むばかりでなく、エアシリンダ の耐久性が低下するという問題がある。さらに、洗浄布用巻き取りローラを回転 させる装置として前記のようにエアシリンダと巻き取りローラとの間にピニオン とセグメントギアとが用いられているので、安定した動作を得るためには、これ らピニオンとセグメントギアとを常時噛合った状態にしておかなければならず、 装置全体を洗浄位置から退去位置へ大きく移動させる場合にも巻き取りローラが 回転し、不必要な洗浄布が巻き取られて洗浄布を浪費するという問題がある。 However, in such conventional impression cylinder cleaning equipment, cleaning as described above is not possible. The cloth take-up roller is driven by an air cylinder and rotates intermittently, so Having to install a dedicated air cylinder for removal increases equipment costs, and Additionally, the piston rod of the air cylinder must be constantly reciprocated during the cleaning process. Not only does it consume a large amount of air, increasing operating costs, but also the air cylinder There is a problem that the durability of Furthermore, the cleaning cloth take-up roller is rotated. As mentioned above, a pinion is installed between the air cylinder and the take-up roller. and segment gears are used, so in order to obtain stable operation, this is necessary. The pinion and segment gear must be kept in mesh at all times. The take-up roller is also used when moving the entire device from the cleaning position to the removal position. There is a problem in that the cleaning cloth rotates and unnecessary cleaning cloth is wound up, wasting the cleaning cloth.
【０００５】 また、特開平３−１１４７４８号公報には、装置全体をエアシリンダで揺動さ せることにより、パッドに添接された洗浄布を版胴の周面に対し接離するように 洗浄位置と退去位置との間で移動させ、また、洗浄作業中の爪かわし時には、カ ム機構により装置を揺動させてこの揺動動作でピニオンをセグメント内歯ギアと 噛合わせながら周回させることにより、爪をかわすとともに、ピニオンと同軸上 に一方向クラッチを介して設けた洗浄布用巻き取りローラを回動させて洗浄布を 巻き取るようにした装置が開示されており、この場合、エアシリンダのピストン ロッドと装置側レバーとの連結部を長孔とピンとの係合にすることにより、爪か わしのときに装置側レバーが揺動してもこれがピストンロッド側に及ばないよう に構成されており、また、装置全体をエアシリンダで圧胴周面から大きく退去さ せるときには、前記セグメント内歯ギアを別のエアシリンダでピニオンから離間 させることにより、装置が揺動しても洗浄布が巻き取られないように構成されて いる。[0005] In addition, Japanese Patent Application Laid-Open No. 3-114748 discloses that the entire device is swung by an air cylinder. By doing so, the cleaning cloth attached to the pad is brought into contact with and away from the circumferential surface of the plate cylinder. When moving between the cleaning position and the withdrawal position, and when dodging the nails during cleaning, The device is swung by the mechanism, and this swiveling action connects the pinion to the segment internal gear. By rotating while meshing, it avoids pawls and is coaxial with the pinion. A cleaning cloth take-up roller provided via a one-way clutch is rotated to take up the cleaning cloth. A device is disclosed for winding the piston of an air cylinder. By making the connecting part between the rod and the lever on the device side engage with the elongated hole and the pin, the claw Even if the lever on the device side swings during operation, this should not affect the piston rod side. In addition, the entire device is moved away from the impression cylinder circumferential surface using an air cylinder. When setting the segment internal tooth gear to the pinion, use another air cylinder to separate the segment internal tooth gear from the pinion. This structure prevents the cleaning cloth from being wound up even when the device swings. There is.
【０００６】 しかしながら、このような従来の装置においては、ピニオンとセグメントギア とを用いているので、その加工や組付けが面倒で経費が嵩むばかりでなく、洗浄 布やパッドの交換などのために洗浄装置を機外に取り出したのち再度取付けると きにギアを噛合わさなければならないので、作業が困難で作業性が悪いという問 題がある。[0006] However, in such conventional devices, pinions and segment gears Because of this, not only is processing and assembly troublesome and expensive, but cleaning is also difficult. If you take the cleaning device out of the machine to change cloths or pads, etc., and then reinstall it, The problem is that the work is difficult and the work efficiency is poor because the gears have to mesh at the same time. There is a problem.
【０００７】 本考案は以上のような点に鑑みなされたもので、構造が簡単で専用の帯状体駆 動装置を必要としない圧胴洗浄装置を提供することを目的としている。[0007] The present invention was developed in view of the above points, and has a simple structure and a dedicated strip drive. The object of the present invention is to provide an impression cylinder cleaning device that does not require a moving device.

【００１５】 以上のように構成された圧胴洗浄装置の動作を説明する。印刷作業の合間に圧 胴２を洗浄する場合には、印刷作業中、圧胴２の周面から退去していた洗浄ユニ ット４を回動させてパッド１４を介して洗浄布８を圧胴２の周面に圧接させたの ち、圧胴２を回転させると、圧胴２の周面に付着したインキや紙粉などの異物が 洗浄布８で拭き取られる。この場合、圧胴２の軸端部に固定されたカムの外周カ ム面には、支持軸３に固定されたレバーの遊端部に設けたカムフォロアが対接さ れており、パッド１４が圧胴２の外周切欠き内に設けられた爪に対応すると、こ のときカムフォロアがカム面の山部を乗り越え、支持軸３が所定角度ずつ正逆方 向に往復回動する。この結果、支持軸３に固定された洗浄ユニット４が揺動し、 図２に示すようにパッド１４が爪に対応する前に爪から逃げ、爪に対応したあと 図１に示すように洗浄位置へ復帰するという爪かわし動作が行われる。そして、 洗浄ユニット４が図２に示す爪かわし位置から図１に示す洗浄位置へ移動すると きに、遊端部をピン２０に当接させたレバー１６が、引っ張りばね２１の引っ張 り力に抗して図の時計方向に回動し、一方向クラッチ１７を介し巻き取りローラ １２が回動するので、異物の付着した洗浄布８が間欠的に巻き取られ、圧胴２の 周面には巻き戻しローラ９から巻き戻された新たな洗浄布８が次々に対接する。 なお洗浄布８は、巻き取りに際して圧胴２の周面の周回方向と逆方向に走行する ので、このときにも異物が拭き取られる。そして、洗浄ユニット４が洗浄位置か ら爪かわし位置へ移動するときには、レバー１６が引っ張りばね２１の引っ張り 力によって図の反時計方向に回動するが、巻き取りローラ１２と端軸１１との間 には、一方向クラッチ１７が介装されているので、巻き取りローラ１２は回動し ない。巻き戻しローラ９に巻かれた洗浄布８が無くなったときには、前記のよう にして洗浄ユニットを取り外したのち、押え板７を取り外し、空の巻き戻しロー ラ９と、洗浄布８がいっぱい巻かれた巻き戻しローラ９と交換する。[0015] The operation of the impression cylinder cleaning device configured as above will be explained. Pressure between printing jobs When cleaning cylinder 2, remove the cleaning unit that was removed from the circumference of impression cylinder 2 during printing. The cleaning cloth 8 is pressed against the circumferential surface of the impression cylinder 2 through the pad 14 by rotating the pad 4. When the impression cylinder 2 is rotated, foreign matter such as ink and paper dust attached to the circumferential surface of the impression cylinder 2 is removed. It is wiped off with a cleaning cloth 8. In this case, the outer circumference of the cam fixed to the shaft end of the impression cylinder 2 is A cam follower provided at the free end of the lever fixed to the support shaft 3 is in contact with the cam surface. When the pad 14 corresponds to the claw provided in the notch on the outer periphery of the impression cylinder 2, this occurs. When , the cam follower climbs over the peak of the cam surface, and the support shaft 3 moves forward and backward by a predetermined angle. It rotates back and forth in the direction. As a result, the cleaning unit 4 fixed to the support shaft 3 swings, As shown in FIG. 2, the pad 14 escapes from the nail before it corresponds to the nail, and after the pad 14 corresponds to the nail, As shown in FIG. 1, a claw dodging operation is performed to return to the cleaning position. and, When the cleaning unit 4 moves from the claw dodging position shown in FIG. 2 to the cleaning position shown in FIG. At this time, the lever 16 whose free end is in contact with the pin 20 is pulled by the tension spring 21. The take-up roller rotates clockwise in the figure against the force of 12 rotates, the cleaning cloth 8 with foreign matter attached to it is intermittently wound up and rolled up on the impression cylinder 2. New cleaning cloths 8 rewound from the unwinding roller 9 come into contact with the peripheral surface one after another. Note that when the cleaning cloth 8 is wound up, it runs in the opposite direction to the direction in which it goes around the circumferential surface of the impression cylinder 2. Therefore, foreign matter is also wiped off at this time. Is the cleaning unit 4 in the cleaning position? When moving from the position to the claw dodging position, the lever 16 is pulled by the tension spring 21. It rotates counterclockwise in the figure due to force, but between the take-up roller 12 and the end shaft 11. Since a one-way clutch 17 is interposed in the , the take-up roller 12 does not rotate. do not have. When the cleaning cloth 8 wound around the rewinding roller 9 runs out, as described above, After removing the cleaning unit, remove the presser plate 7 and remove the empty rewind roller. The roller 9 is replaced with a rewind roller 9 fully wrapped with the cleaning cloth 8.
【００１６】 なお、本実施例では帯状体として洗浄布８を例示したが、帯状に形成された紙 製の洗浄体を用いてもよい。また、本実施例においては、巻き取りローラ１２の 端部として巻き取りローラ１２とは別体で一体的に回転する端軸１１を例示した が、これに限定するものではなく、巻き取りローラ１２と一体形成された端軸な どでもよい。[0016] Note that in this embodiment, the cleaning cloth 8 is used as an example of a strip-shaped body, but a paper formed in a strip-shaped body may also be used. You may also use a cleaning body manufactured by Further, in this embodiment, the winding roller 12 As an example, an end shaft 11 that rotates integrally with the winding roller 12 separately from the winding roller 12 is shown as an example. However, the invention is not limited to this, and may include an end shaft formed integrally with the take-up roller 12. I don't care.

以上の説明により明らかなように本考案によれば、パッドに添接された帯状体 を圧胴の周面に圧接させ、帯状体巻き取りローラの回動によりこの帯状体を走行 させて圧胴の周面を洗浄するとともに、圧胴のくわえ爪装置がパッドを通過する ときに装置全体を圧胴の半径方向に移動させてくわえ爪装置から逃がす爪かわし 機構を備えた印刷機の圧胴洗浄装置において、帯状体巻き取りローラの端部に、 一方向クラッチを介してレバーを支持させ、装置全体が爪かわし位置から洗浄位 置へ移動するときにこのレバーを当接させて帯状体巻き取り方向に回動させるピ ンを機台側に設けたことにより、爪かわし動作を利用して巻き取りローラを回動 させ帯状体を巻き取ることができるので、従来のように巻き取りローラの回動装 置としてエアシリンダなどを設ける必要がなく、構造が簡素化され装置を安価に 提供することができる。また、帯状体は爪かわし時にのみ巻き取られるので、帯 状体の消費量が少なく、経費が節減される。さらに、装置全体の移動動作を巻き 取りローラの回転に変換させる手段がピンとレバーであるため、従来のギア装置 と較べて加工，組付けが容易であり、装置を安価に提供することができるととも に、洗浄ユニットの取り付け，取り外しが容易になり、作業性が向上する。 As is clear from the above explanation, according to the present invention, the strip attached to the pad is brought into pressure contact with the circumferential surface of the impression cylinder, and this strip is run by the rotation of the strip winding roller. At the same time, the impression cylinder gripping device passes through the pad. Sometimes, the entire device is moved in the radial direction of the impression cylinder to escape from the gripping device. In an impression cylinder cleaning device of a printing press equipped with a mechanism, at the end of the strip take-up roller, The lever is supported via a one-way clutch, and the entire device moves from the claw dodging position to the cleaning position. When moving to the position, the lever contacts this lever and rotates it in the direction of winding the strip. By installing the switch on the machine side, the take-up roller can be rotated using the pawl dodging action. Since the belt-shaped material can be wound up, there is no need to rotate the take-up roller like in the past. There is no need to install an air cylinder etc. for the installation, simplifying the structure and making the device cheaper. can be provided. In addition, since the band-like body is only wound up when dodging the nail, the band The amount of material consumed is small, which saves costs. Furthermore, the movement of the entire device is Since the means to convert the rotation into the rotation of the take-up roller is a pin and lever, it is not possible to use a conventional gear device. It is easier to process and assemble compared to In addition, the cleaning unit can be easily installed and removed, improving work efficiency.
