Description
【０００１】[0001]
本考案は、印刷機の洗浄ワイピング装置に関し、特に、オフセット印刷機など の印刷機にあって印刷にかかわる回転胴体の周面を掃拭するための洗浄布を具え た洗浄ワイピング装置に関する。 The present invention relates to a cleaning and wiping device for a printing machine, and more particularly, to a cleaning and wiping device provided with a cleaning cloth for cleaning a peripheral surface of a rotary body involved in printing in a printing machine such as an offset printing machine.
【０００２】[0002]
従来の印刷機として知られているものにオフセット印刷機がある。かかるオフ セット印刷機は一般にその印刷部を構成する版胴，ブランケット胴および圧胴な どの回転胴体を有しており、これらの回転胴体周面から付着した不要なインクを 拭き取ったり、印刷後その被印刷体（以下で記録シートという）に転写されたイ ンクを定着させるための回転胴体である乾燥・冷却用シリンダの周面から付着物 を掃拭したりするために洗浄ワイピング装置が設けられている。そして、このよ うな従来の洗浄ワイピング装置では布または合成繊維製の不織布で形成された洗 浄用シートが用いられてきた。 An offset printing machine is known as a conventional printing machine. Such an offset printing machine generally has a rotating body such as a plate cylinder, a blanket cylinder, and an impression cylinder that constitute the printing section.Wipe off unnecessary ink adhering from the peripheral surface of these rotating bodies, and after printing, A cleaning and wiping device is provided to wipe off adhering substances from the peripheral surface of the drying / cooling cylinder, which is a rotating body for fixing the ink transferred to the printing medium (hereinafter referred to as recording sheet). ing. In such a conventional cleaning and wiping device, a cleaning sheet made of cloth or synthetic fiber non-woven fabric has been used.
【０００３】 かかる洗浄用シートは供給用ロールから巻取用ロールに歩進的に移動させられ ると共に、その間に洗浄液を洗浄用シートに供給して浸み込ませ、洗浄用シート を回転胴体の周面に圧接させつつ、上記移動方向とは反対の方向に回転胴体を回 転させることで、これらの周面上から不要インクやブランケット胴から発生する ゴムの粉、さらには紙粉などが掃拭洗浄される。Such a cleaning sheet is gradually moved from the supply roll to the winding roll, and at the same time, a cleaning liquid is supplied to the cleaning sheet so that the cleaning sheet is impregnated with the cleaning liquid and the cleaning sheet is attached to the rotating body. By rotating the rotating body in the direction opposite to the above-mentioned movement direction while pressing it against the peripheral surface, unnecessary ink, rubber powder generated from the blanket cylinder, and paper powder are wiped from the peripheral surface. It is wiped and washed.
【０００４】[0004]
しかしながら、このような従来の印刷機の洗浄ワイピング装置にあっては、洗 浄用シートに使用されている、例えばナイロン等合成繊維製の不織布の吸水性が 低いために洗浄液が十分に含浸されず、回転胴体回りの汚れを掃拭するに十分で なく、所望の洗浄効果を挙げることができないという問題があった。 However, in such a conventional cleaning and wiping device for a printing machine, the cleaning liquid is not sufficiently impregnated because the nonwoven fabric made of synthetic fiber such as nylon used in the cleaning sheet has low water absorption. However, there is a problem in that it is not sufficient to wipe off stains around the rotating body and the desired cleaning effect cannot be obtained.
【０００５】 このように十分な洗浄効果が得られないと、その結果、記録シート上にその汚 れが転写されることによって、印刷された画像の品位が損ねられる。If a sufficient cleaning effect is not obtained in this way, as a result, the dirt is transferred onto the recording sheet, and the quality of the printed image is impaired.
【０００６】 また、ワイピング性能を向上させ洗浄用シートへのインクやごみの堆積を防ぐ ためには、新しい洗浄用シートを頻繁に、例えば約３０秒に１回の割合で回転胴 体との圧接位置に歩進的に送り出す必要があることから高速印刷性能に支障をき たす問題があった。Further, in order to improve the wiping performance and prevent the accumulation of ink and dust on the cleaning sheet, a new cleaning sheet is frequently contacted with the rotating body, for example, once every about 30 seconds. There was a problem that it hindered high-speed printing performance because it was necessary to send it to the position step by step.
【０００７】 本考案の目的は、上述した従来の問題点を解消し、洗浄液を含浸した状態で回 転胴体の周面に圧接させつつ移動させるに十分な強度を有すると共に優れた吸水 性によりワイピング性能の向上と安定した洗浄効果が得られる洗浄用シートを用 いることで、高速印刷性能を維持しつつ所定の良好な印刷が期待できる印刷機の 洗浄ワイピング装置を提供することにある。An object of the present invention is to solve the above-mentioned conventional problems and to have wiping due to its excellent water absorption and having sufficient strength to move while being in pressure contact with the peripheral surface of the rotating body in a state of being impregnated with a cleaning liquid. It is an object of the present invention to provide a cleaning wiping device for a printing press, which can expect high-quality printing while maintaining high-speed printing performance, by using a cleaning sheet that improves performance and provides a stable cleaning effect.
【０００８】[0008]
かかる目的を達成するために、本考案は、ポリエステル繊維と木材パルプ繊維 との混合になる不織布で帯状に形成され回転する胴体の印刷にかかわる周面に少 なくとも線接触の状態で該周面の洗浄掃拭が可能な洗浄用シートと、該洗浄用シ ートを前記回転する胴体の周面に圧接した状態に保つ押圧手段と、前記洗浄用シ ートを所定のタイミングで前記周面に沿ってその回転方向とは逆方向に移動させ る洗浄用シート移動手段と、該移動手段の移動方向の前記押圧手段上流側に配設 され、前記洗浄用シートに洗浄液を供給する洗浄液供給手段とを具備したことを 特徴とするものである。 In order to achieve such an object, the present invention is directed to a peripheral surface of a rotating body, which is formed of a non-woven fabric which is a mixture of polyester fiber and wood pulp fiber, in a state of at least line contact with the peripheral surface involved in printing. Cleaning sheet capable of cleaning and wiping, the pressing means for keeping the cleaning sheet in pressure contact with the peripheral surface of the rotating body, and the cleaning sheet at a predetermined timing with the peripheral surface. A cleaning sheet moving means for moving the cleaning sheet along a direction opposite to the rotating direction, and a cleaning liquid supplying means arranged upstream of the pressing means in the moving direction of the moving means and supplying a cleaning liquid to the cleaning sheet. It is characterized by being equipped with.
【０００９】[0009]
本考案によれば、洗浄液供給手段により洗浄液が供給された洗浄用シートはポ リエステル繊維と木材パルプ繊維との混合になる不織布であるために、押圧手段 によって回転する胴体の周面に押圧されても十分に洗浄液を含浸した状態に保つ ことができ、その摺接によって効率良く、かつ耐摩耗性を保持して周面から汚れ を洗浄掃拭することができる。また、洗浄用シートの摺接部により十分汚れが吸 収掃拭されるタイミングで洗浄用シート移動手段により移動が行われて、洗浄用 シートの新たな部分による洗浄掃拭が繰返されるので、安定した確実な洗浄ワイ ピング動作を長期にわたり実施することができる。 According to the present invention, since the cleaning sheet supplied with the cleaning liquid by the cleaning liquid supply device is a non-woven fabric which is a mixture of polyester fibers and wood pulp fibers, it is pressed against the peripheral surface of the rotating body by the pressing device. Can be sufficiently impregnated with the cleaning liquid, and its sliding contact can efficiently and wear-resisting to clean and wipe dirt from the peripheral surface. In addition, since the cleaning sheet moving means moves at the timing when the sliding contact portion of the cleaning sheet absorbs and wipes off enough dirt, cleaning and wiping with a new portion of the cleaning sheet is repeated, so it is stable. The reliable cleaning and wiping operation can be performed for a long period of time.

以下に、図面を参照しつつ本考案の実施例を具体的に説明する。 Embodiments of the present invention will be specifically described below with reference to the drawings.
【００１１】 図１は本考案にかかる洗浄ワイピング装置の構成例を示す。なお、印刷機全体 の構成についてはここで示さないが、２０はオフセット印刷機の印刷部を構成し ている回転胴体、すなわち、版胴，ブランケット胴，圧胴もしくは冷却用のシリ ンダのいずれか１つを示す。１はこのような回転胴体２０の周面２０Ａに圧接し 、その表面を洗浄掃拭する洗浄ワイピング装置である。２はその洗浄ワイピング 作用のために前記周面２０Ａに摺接しつつ、矢印方向に所定のタイミングで歩進 送りされる帯状に形成された本考案にかかる洗浄用シートであり、木材パルプと ポリエステル繊維との不織布で形成されている。なお、この洗浄用シート２につ いては後で詳述する。FIG. 1 shows an example of the structure of a cleaning and wiping device according to the present invention. Although the structure of the entire printing machine is not shown here, 20 is a rotating body constituting the printing section of the offset printing machine, that is, either a plate cylinder, a blanket cylinder, an impression cylinder or a cooling cylinder. Show one. Reference numeral 1 denotes a cleaning and wiping device which presses against the peripheral surface 20A of the rotary body 20 and cleans and wipes the surface. Reference numeral 2 denotes a cleaning sheet according to the present invention, which is formed in a strip shape and is slidably contacted with the peripheral surface 20A for its cleaning and wiping action, and is stepwise fed in a predetermined timing in an arrow direction. And non-woven fabric. The cleaning sheet 2 will be described later in detail.
【００１２】 ３は洗浄用シート２を巻回した状態に保持する供給ロール、４は供給ロール３ から繰り出され、回転胴体２０の周面２０Ａを洗浄掃拭した後の洗浄用シート２ を巻取る巻取ロールであり、供給ロール３から繰り出された洗浄用シート２はガ イドローラ５および６を経て、巻取ロール４に巻取られるが、その途中で回転胴 体周面２０Ａに向けて偏倚される押圧部材７により洗浄用シート２が上記周面２ ０Ａに押圧された状態に保たれる。なおここで、洗浄用シート２は押圧部材７に より回転胴体周面２０Ａとその軸方向に少なくとも線接触するように構成されて おり、洗浄ワイピング装置１は回転胴体２０に対して洗浄用シート２をそのよう な姿勢に保つように配設される。また、８は洗浄用シート２の矢印で示す送り出 し方向に対して押圧部材２の上流側に設けられ、洗浄用シート２に向けて洗浄液 を噴射し供給する洗浄液供給ノズル、９は洗浄ワイピング装置１自体の筐体であ る。なお、洗浄液としては、インク溶剤ないし、通常の水か、またはこれらの適 宜混合になるものなど、自在に選択されてよい。3 is a supply roll that holds the cleaning sheet 2 in a wound state, 4 is unrolled from the supply roll 3, and the cleaning sheet 2 is wound after the peripheral surface 20 A of the rotary body 20 is cleaned and wiped. The cleaning sheet 2 which is a take-up roll and is fed from the supply roll 3 passes through the guide rollers 5 and 6 and is taken up by the take-up roll 4, but is biased toward the peripheral surface 20A of the rotating body midway. The cleaning sheet 2 is held in a state of being pressed against the peripheral surface 20A by the pressing member 7 that is. Here, the cleaning sheet 2 is configured so that the pressing member 7 makes at least a line contact with the rotary body peripheral surface 20A in the axial direction thereof, and the cleaning wiping device 1 makes the cleaning sheet 2 with respect to the rotary body 20. Is arranged so as to maintain such a posture. A cleaning liquid supply nozzle 8 is provided on the upstream side of the pressing member 2 with respect to the feeding direction of the cleaning sheet 2 indicated by an arrow, and sprays and supplies the cleaning liquid toward the cleaning sheet 2, and 9 is a cleaning wiping. It is the housing of the device 1 itself. The cleaning liquid may be selected freely, such as an ink solvent, ordinary water, or an appropriate mixture thereof.
【００１３】 ついで、このように構成した印刷機の洗浄ワイピング装置による洗浄掃拭動作 について説明する。Next, a cleaning / wiping operation by the cleaning / wiping device of the printing press thus configured will be described.
【００１４】 先にも述べたように、洗浄ワイピング装置１は一定量づつ矢印方向に回転する 版胴などの回転胴体２０の周面２０Ａにその洗浄用シート２が圧接の形で少なく とも線接触を保つように印刷機側に保持されており、その摺接状態で洗浄用シー ト２により周面２０Ａからインクやごみによる汚れが洗浄液によって洗われつつ 、掃き取られる。なおこの場合、洗浄液は押圧部材２の上流側で洗浄液供給ノズ ル８からの噴射によって洗浄用シート２に供給されるもので、本考案にかかる洗 浄用シート２は後述するように十分な吸水性を有しているために、回転胴体周面 ２０Ａを洗浄掃拭する状態で洗浄液の不足をきたすようなことがない。As described above, the cleaning and wiping device 1 rotates in the direction of an arrow by a constant amount. The cleaning sheet 2 is in pressure contact with the peripheral surface 20A of the rotary body 20 such as a plate cylinder, at least in line contact. The cleaning sheet 2 is wiped away from the peripheral surface 20A by the cleaning liquid while being kept in contact with the printing machine by the cleaning sheet 2. In this case, the cleaning liquid is supplied to the cleaning sheet 2 by injection from the cleaning liquid supply nozzle 8 on the upstream side of the pressing member 2, and the cleaning sheet 2 according to the present invention has sufficient water absorption as described later. Since it has the property, there is no shortage of the cleaning liquid when the peripheral surface 20A of the rotating body is cleaned and wiped.
【００１５】 かくして一定量回転する回転胴体２０に対してこれに圧接した形で洗浄掃拭が 済むと、その都度不図示のステッピングモータなどで構成される洗浄シート移動 手段により洗浄用シート２は矢印方向に歩進的に所定量移動され、巻取リール４ に巻取られて洗浄用シート２の新たな部分が押圧部材７によって回転胴体周面２ ０Ａに向け圧接され、次の洗浄掃拭のための待機状態となる。When the cleaning / wiping is completed in such a manner that the rotating body 20 rotating by a certain amount is pressed against the rotating body 20, the cleaning sheet 2 is moved by the cleaning sheet moving means constituted by a stepping motor or the like (not shown). Direction by a predetermined amount, is wound up by the take-up reel 4, and a new portion of the cleaning sheet 2 is pressed against the peripheral surface 20A of the rotating body by the pressing member 7 for the next cleaning and wiping. It will be in a standby state for.
【００１６】 なお、押圧部材７を回転胴体周面２０Ａに向けて偏倚させる手段としては示し てないが、エアシリンダ，油圧シリンダ，電磁式あるいはロータリアクチュエー タ等いずれであってもよい。また、押圧部材７の押圧面も、図１に示すような円 弧面の外、掃拭可能なブレード式とするなり、さらにはかかるものを弾性体で形 成するようにしてもよい。Although not shown as means for biasing the pressing member 7 toward the peripheral surface 20A of the rotary body, any of an air cylinder, a hydraulic cylinder, an electromagnetic type, a rotary reactor, or the like may be used. Further, the pressing surface of the pressing member 7 is not limited to the circular arc surface as shown in FIG. 1 but is a blade type capable of being wiped, and further, such a member may be formed of an elastic body.
【００１７】 ついで、本考案にかかる洗浄用シート２について詳述する。本例の洗浄用シー ト２は木材パルプと繊維とポリエステル繊維との混合からなる不織布を帯状に形 成したもので、かかる不織布の好適例として、Ｅ．Ｉ．デュポン・ドゥ・ヌムー ル・アンド・カンパニーから市販されているスパンレースド不織布であるソンタ ラ（Ｓｏｎｔａｒａ（登録商標名））を用いることができる。Next, the cleaning sheet 2 according to the present invention will be described in detail. The cleaning sheet 2 of this example is a non-woven fabric formed of a mixture of wood pulp, fibers, and polyester fibers in a band shape. I. Sontara (registered trademark), which is a spunlaced nonwoven fabric commercially available from DuPont de Numour & Co., can be used.
【００１８】 このようなスパンレースド不織布は、木材パルプ繊維と合成有機繊維とからな る集合体を、例えば細かい金鋼等で支持しながら、０．０５〜０．１３ｍｍの直 径を有するオリフィスのバンクから細い柱状の水を噴流処理して、噴流のエネル ギーＥと噴流の衝撃力Ｉとの積であるＥ・Ｉを供給することにより製造される。 そこで、このようにして得られたスパンレースド不織布では、ランダムな方向に 並んだ数百万の木材パルプ繊維と合成有機繊維とが絡み合って形成されており、 非常に高い細菌バリヤー性を有している。Such a spunlaced nonwoven fabric is an orifice having a direct diameter of 0.05 to 0.13 mm while supporting an aggregate composed of wood pulp fibers and synthetic organic fibers with, for example, fine gold steel. It is manufactured by subjecting a thin column of water to jet treatment from the bank of No. 1 and supplying E · I which is the product of the energy E of the jet and the impact force I of the jet. Therefore, the spunlaced nonwoven fabric obtained in this way is formed by intertwining millions of wood pulp fibers and synthetic organic fibers arranged in random directions, and has a very high bacterial barrier property. ing.
【００１９】 またこのようなスパンレースド不織布の中でも廉価であり吸水性等の要求を満 足するものとしては木材パルプ繊維とポリエステル繊維との混合体であることが 望ましく、この場合の木材パルプ／ポリエステルの混合比は７０〜３０％／３０ 〜７０％であり、好ましくは６０〜４０％／４０〜６０％に保たれるものがよい 。Further, among such spunlaced nonwoven fabrics, a mixture of wood pulp fiber and polyester fiber is preferable as a material which is inexpensive and satisfies the requirements such as water absorbency. The mixing ratio of the polyester is 70 to 30% / 30 to 70%, preferably 60 to 40% / 40 to 60%.
【００２０】 さらにまた、この木材パルプ／ポリエステルからなるスパンレースド不織布の 目付量は、両者の混合比等にも依存するが、５０〜２５０ｇ／ｍ2 の混合比、好 ましくは１００〜２００ｇ／ｍ2 の範囲内としたものがよい。Further, the weight per unit area of the spunlaced nonwoven fabric made of wood pulp / polyester depends on the mixing ratio of the both, but the mixing ratio is 50 to 250 g / m 2 , preferably 100 to 200 g. It is preferably within the range of / m 2 .
【００２１】 なお、木材パルプ繊維とポリエステル繊維とからなるスパンレースド不織布の 掴み破壊強度は、繊維の絡み具合にも依存するが、ほぼ１０．４ないし２２．６ ｋｇであり極めて強靭である。The gripping breaking strength of the spunlaced nonwoven fabric composed of wood pulp fibers and polyester fibers depends on the entanglement of the fibers, but is approximately 10.4 to 22.6 kg, which is extremely strong.
【００２２】 特に吸水性と目付量との関係を表１に示す。従来の洗浄ワイピング装置用洗浄 布として使用されてきたポリエステル繊維とポリビニルアルコール繊維とからな る比較用の不織布と、本考案に用いることができる不織布の実施例として、木材 パルプ繊維とポリエステル繊維とがこの表１に示す割合で混合されたもの、デュ ポン社製ソンタラ（商品名）型番８８０１および８８０５との吸水量を比較した 結果を示した。In particular, Table 1 shows the relationship between the water absorption and the basis weight. A comparative non-woven fabric composed of polyester fiber and polyvinyl alcohol fiber, which has been used as a cleaning cloth for a conventional cleaning and wiping device, and a non-woven fabric that can be used in the present invention, include wood pulp fiber and polyester fiber. The results of comparing the water absorption amounts with those mixed in the proportions shown in Table 1 and Sontara (trade name) model numbers 8801 and 8805 manufactured by DuPont are shown.
【００２３】[0023]
【表１】 [Table 1]
【００２４】 この表１から明らかなように目付量が大きい木材パルプ／ポリエステル繊維か らなる不織布の吸水量は、ポリエステル／ポリビニルアルコール繊維不織布の吸 水量の約３倍であった。そこで、このような木材パルプ／ポリエステル不織布を 洗浄ワイピング装置の洗浄用シート２として使用した場合、ワイピング性能とし てその繰り出しインターバルが約５分に１回で十分洗浄効果を得られることが確 認できた。As is clear from Table 1, the water absorption of the non-woven fabric made of wood pulp / polyester fiber having a large basis weight was about three times the water absorption of the polyester / polyvinyl alcohol fiber non-woven fabric. Therefore, when such a wood pulp / polyester non-woven fabric is used as the cleaning sheet 2 of the cleaning and wiping device, it can be confirmed that the wiping performance is sufficient if the feeding interval is about once every 5 minutes. It was
【００２５】 なお、これまでに述べてきた実施例では、好適例として、印刷機が複数の回転 胴体を有するオフセット印刷機の場合についてであったが、本考案の適用は、か かるオフセット印刷機に限られるものではなく、その印刷部に記憶媒体などによ って汚れ易い回転胴体を有する印刷機に広く適用できることはいうまでもない。In the embodiments described so far, the case where the printing press is an offset printing press having a plurality of rotating bodies has been described as a suitable example, but the application of the present invention is applicable to such offset printing press. It is needless to say that the present invention is not limited to the above, but can be widely applied to a printing machine having a rotating body in the printing portion that is easily soiled by a storage medium.
【００２６】[0026]
以上説明してきたように、本考案によれば、ポリエステル繊維と木材パルプ繊 維との混合になる不織布で帯状に形成され回転する胴体の印刷にかかわる周面に 少なくとも線接触の状態で該周面の洗浄掃拭が可能な洗浄用シートと、該洗浄用 シートを前記回転する胴体の周面に圧接した状態に保つ押圧手段と、前記洗浄用 シートを所定のタイミングで前記周面に沿ってその回転方向とは逆方向に移動さ せる洗浄用シート移動手段と、該移動手段の移動方向の前記押圧手段上流側に配 設され、前記洗浄用シートに洗浄液を供給する洗浄液供給手段とを具備したので 、その洗浄用シートが十分な吸水性，耐摩耗性と共に包含力および均一性を有し ていることから回転胴体周面に圧接して洗浄掃拭を行うにあたり拭きむらのない 掃拭を実施することができ、また、洗浄液を十分に含浸した状態で効率良く洗浄 が行える外、洗浄用シート自体がその湿乾にかかわらず十分な機械的強度を有す るので、洗浄用シート供給にかかわる部材の設計に幅を持たせることができる。 また、洗浄用シートがインクやごみなどの吸着に十分な包含力を有するので、延 命効果が得られる。さらにまた、ほぐれ難いことから不織布を形成しているポリ エステル繊維や木材パルプ繊維の糸状体が掃拭時に回転胴体側に付着して、記録 シート上に再転移され、印刷の品位を損うような虞がない。 As described above, according to the present invention, the peripheral surface of the rotating body, which is formed of a non-woven fabric that is a mixture of polyester fiber and wood pulp fiber, is in line contact with at least the peripheral surface involved in printing. Cleaning sheet capable of cleaning and wiping, the pressing means for keeping the cleaning sheet in pressure contact with the peripheral surface of the rotating body, and the cleaning sheet along the peripheral surface at a predetermined timing. The cleaning sheet moving means is arranged to move in a direction opposite to the rotating direction, and the cleaning solution supplying means is arranged upstream of the pressing means in the moving direction of the moving means and supplies the cleaning solution to the cleaning sheet. Therefore, since the cleaning sheet has sufficient water absorbency and abrasion resistance, as well as inclusion power and uniformity, a uniform cleaning is performed when performing cleaning and cleaning by pressing against the peripheral surface of the rotating body. Do The cleaning sheet itself has sufficient mechanical strength regardless of whether it is wet or dry, so that the cleaning sheet can be efficiently cleaned while it is sufficiently impregnated with the cleaning solution. Can have a wide range of designs. In addition, the cleaning sheet has a sufficient inclusion force for adsorbing ink, dust, etc., so that a life prolonging effect can be obtained. Furthermore, since it is difficult to loosen, the filaments of polyester fibers and wood pulp fibers forming the non-woven fabric adhere to the rotating body side during wiping and are retransferred onto the recording sheet, impairing the printing quality. There is no fear.
