Description of the Invention: [Technical Field] The present invention relates to a coating machine for polishing a printing surface, and the like, and more particularly to a coating having a high viscosity such as an ultraviolet curing resin coating. A coating machine coated on paper. [Prior Art]

先前，為了將紫外線硬化型樹脂塗料塗佈於紙張之表 面上’係使用凹板印刷塗佈機、3根|昆塗佈機、4根輥指 向式塗佈機等，然而使用該等塗佈機難以塗佈例如3〇〇 C.P.S.以上之高黏度塗料。此外’通常為人所周知的是， 很難將適於紙表面加工之無溶劑之紫外線硬化型樹脂塗料 的黏度降低’例如使其黏度未滿3〇〇 c.P.s。 與此相對，眾所周知的是反向式輥塗機可塗佈黏度較 高之塗料，但通常難以將該方式應用於對紙張進行塗佈。 尤其係該方式存在以下問題：即便使用供紙機構之進給輥 進給紙張，亦不可能通過反向式輥塗機之反向旋轉中之塗 佈輥與支承繞之間；即便紙張能夠通過，紙張之 沾有較厚的塗料液；此外於紙張之後端部通過上述進給棍 後’因紙張進給速度產生變化而導致塗佈面上出現分界 線’結果造成塗佈不均句；$而，若根據紙張 1 顯不經濟。價格4且作業性方面考慮明 本實公昭 4所示， 為解決該等問題，本案申請人開發出一 59-24386號公報所揭示之塗裝機。該塗裝機 5 200920604 於反向式棍塗機21之塗佈 支承親25於紙張移動方^22^^置支承親以’該 主體部25a之外周面的 、以支承輥25之 26 > ^ , +·、圓周方向上之—部份形成有壓溝_ 20，且以不自上述主體 巧芏屏帽 有帶狀物27之安裳機構/之外周面向外突出之方式設 係數較大且具有彈性之:：。上述帶狀物27由橡勝等摩擦 而以可裝卸之方I::，而成，並藉由安裝手“ 邙25 Μ田 拉緊狀態下捲繞於支承輥25之主體 邛25a的外周面上。上述 體 桿29,擺動桿29之 ：5之轴…系軸支於擺動 端部安裝有可自由旋轉之凸輪從動“： 動透過凸輪從動件3〇受操作機構3 輪機構之驅料段3^、自具制服馬達與行星齒 ^ , 透過轴34傳輸至該等凸輪32、33。 構36報25以及塗佈輥22之後側配置有後述供紙機 ^ ’於該供紙機構36之後側配置有供紙機37,進而於 叉承親2 5以及爹佑φ日 乂 紙機構36且備前進二則方配置有輸送帶38。上述供 、備則進給輥39、後進給輥40以及前規41， 5亥則進給輕3 Q目士， 具有上下— "有上下一對之輥39a、39b，後進給輥4〇 門· _下對之輥4〇a、40b，前規41設於前後進給輥之 叮 ^ 之上側輥39a與後進給輥40之上側輥40a 勹於上下方向 ,,„ ° 擺動。而且’對應於供紙機37供給一張 A張之動作， _ 支承輥25旋轉一圈並且上下往返運動一次， 則規41上下運 & ^ 後進心幸 逆勤1 —人，且刖進給輥39之上側輥39a以及 40之上側輥40a分別上下運動1次。此外，各個 200920604 輥及凸輪往圖中箭頭方向旋轉。 繼而’說明以上述方式構成之紙 ::紙機37供給-張紙張後，該紙張通過:=:進 給輥40之上側輥4〇a 巧正上升之後進 之下方，紙張前端接 規4!而暫時停止動作。前規* 升刚 40 ^ h /ml h ^ 與此同時後進給輥 40之上側輥40a下降，從而向 iK 移k紙張。該紙張到達 别進給輥39後，由於其上側 m J ^ 谁紙和μ ^、， 側輮39a為下降狀態，因此由前 進…9向可方移送紙張’與此同 側輥_上升，由後進給輥4〇移 ：=4〇之上 k，A張之動作結束。此外， 於、我張之前端部被移送至反向 J八視堂機21之塗佈輥22與 / ^ 25之接點時，藉由操作機構31之第！凸輪32之 =’該凸輪之凸部仏透過凸輪從料30而使擺動桿29 、疋，將支承輥25抬高，並透過帶狀物27將紙張塵接於 塗佈輥22上。與此同時，前進給報39之上側親…上升， 從而由前進給輥39移送紙張之動作結束。 夕，、再=，在此之前，前規41上升，以使下一紙張不會被 移送往前方。另外，由於上述帶狀物27之摩擦力較大， 八與紙張之間之摩擦力大於紙張與塗料及塗佈輥22之間 的摩擦力，故支承輥25上升，並隔帶狀物27及紙張而壓 $於塗佈輥22後，紙張便—面藉由支承輥25之旋轉而向 刖方移送，一面藉由塗佈輥22而塗佈塗料。當將紙張於 該狀態下向前方移送某程度後，由於旋轉方向上存在相位 差’因此使得凸輪從動件30傳遞至第i凸輪32之凸部33a， 且於紙張之後端部到達支承輥25與塗佈輥22之接點時， 200920604 凸輪從動件30自第2凸輪33之凸部…脫離，支承以5 於重力作用下使擺動桿29旋動並下降，與塗料22 後即結束塗佈作業。此時，紙張之前部放於輸送帶Μ上， 因此支承輥25下降後立刻驅動輸送帶38,藉此搬出紙張。 此外，由於必須根據紙張之長度以及紙張與塗佈輥之 間之摩擦係數的變化，變更第！凸輪32之凸部^盘第^ 凸輪33之凸部33a於圓周方向上連動之長度，故而藉由相 對於軸34來旋動調整第2凸輪33，而調整第}凸輪μ之 凸部32a與第2凸輪33之&部33&重疊之長度之改變。而 且，轉動調整第2 Λ輪33時’較佳為利用驅動機構35中 有使用仃星齒輪機構之情況，於旋轉過程中實際觀察已塗 扃氏張並進仃調整’或者於前方設置檢測紙張前端部之 機構來進行調整。此外，上述帶狀物使用寬度較塗裝之紙 張之寬度略窄的帶狀物，以使帶狀物上不附著塗料之方 式’根據紙張寬度適當更換並使用適當寬度之帶狀物。 此創作中，可對供紙機構作適當變更，例如使用擺 動式夹甜或具鍵條之規，此外’操作機構並不-定褐限於 上述貫施例。 “如上述說明，此創作之紙張用塗裝機具備反向式輥塗 機、支承輥、帶狀物、操作機構以及供紙機構，支承輥係 :主體部之圓周方向上設有壓溝槽’帶狀物係藉由設於該 屋溝槽内之安裝手段而可裝卸地纏繞於支承輥上，且由摩 示係數較大之彈性物質形成’操作機構係以特定時機使上 述支承輥接觸或離開上述輥塗機之塗佈輥，供紙機構係設 200920604 置於支承輥與上述塗佈輥之後側，並向支承輥與塗佈輥之 間依序供給紙張。 < 因此’利用此創作，以p 招& n 上述刼作機構，使支承輥隔帶 狀，及紙張而壓接於塗佈糙，藉此開始對紙張進行塗裝， 且:由使支承親離開塗佈概而結束塗裝。此外，於塗 :呈由於上述帶狀物與紙張之間之摩擦係數較大，因此 卩使不使用推爪亦可利用支承輥之旋轉—面移送紙張 對紙張進行塗裝。如此，夢 ^ ^ _ 错由使用反向式輥塗機，而可將 钻度尚之塗料均勻塗裝於紙 、 ^ ,, ^ 1無須使用推爪。進而， 於此釗作中，僅根據紙張寬 .?

It is difficult to apply a high viscosity coating such as 3 〇〇 CPS or more. Further, it is generally known that it is difficult to reduce the viscosity of a solvent-free ultraviolet curable resin coating suitable for paper surface processing, for example, such that the viscosity is less than 3 〇〇 c.P.s. On the other hand, it is known that a reverse roll coater can apply a coating having a high viscosity, but it is generally difficult to apply the method to coating paper. In particular, this method has the following problem: even if the paper is fed by the feed roller of the paper feeding mechanism, it is impossible to pass between the coating roller and the support winding in the reverse rotation of the reverse roller coater; even if the paper can pass The paper is coated with a thick coating liquid; in addition, after the end of the paper passes through the above feeding rod, the result is that the boundary line appears on the coated surface due to the change of the paper feeding speed. However, it is not economical if it is based on paper 1. In order to solve these problems, the applicant of the present invention developed a coating machine disclosed in Japanese Laid-Open Patent Publication No. 59-24386. The coating machine 5 200920604 is supported by the coating support 25 of the reverse stick coater 21 on the paper moving side to support the outer peripheral surface of the main body portion 25a to support the roller 25 26 > ^ , +·, in the circumferential direction—partially formed with a pressure groove _ 20, and the coefficient is larger in such a manner that it does not protrude from the outer body of the above-mentioned main body, the screen body has the belt 27 And flexible::. The belt 27 is made of a rubber or the like and is detachably attached to the outer peripheral surface of the main body 邛 25a of the support roller 25 by the mounting hand "邙25 Μ田拉. The above-mentioned body rod 29, the swinging rod 29: the shaft of 5... The shaft is supported at the swinging end with a freely rotatable cam driven ": the moving through cam follower 3 is driven by the operating mechanism 3 wheel mechanism The section 3^, the self-contained motor and the planet teeth ^ are transmitted through the shaft 34 to the cams 32, 33. On the rear side of the coating roller 25 and the coating roller 22, a paper feeder 37 is disposed on the rear side of the paper feeding mechanism 36, and the paper feeder 37 is disposed on the rear side of the paper feeding mechanism 36, and further, the fork bearing 2 and the φ φ 乂 paper feeding mechanism 36 A conveyor belt 38 is disposed on the second side. The above-mentioned supply and backup feed roller 39, rear feed roller 40, and front gauge 41, 5H are fed light 3 Q gauge, have upper and lower - " there are upper and lower pair of rollers 39a, 39b, rear feed roller 4〇 The door _ lower roller 4〇a, 40b, the front gauge 41 is disposed on the front and rear feed rollers ^ the upper side roller 39a and the rear feed roller 40 upper side roller 40a are in the up and down direction, „° oscillate. Corresponding to the action of the paper feeder 37 supplying one sheet A, the support roller 25 rotates one turn and moves up and down once, and the gauge 41 moves up and down, and then enters the heart, and the feed roller 39 The upper side rollers 39a and the upper side rollers 40a are vertically moved once. Further, each of the 200920604 rollers and cams rotates in the direction of the arrow in the figure. Then, the paper constructed as described above is described: the paper machine 37 supplies the sheets of paper, The paper passes: =: The upper roller 4〇a of the feed roller 40 is raised and then moved downward, and the leading end of the paper is attached to the 4! and temporarily stops. The front gauge* is just 40 ^ h /ml h ^ at the same time The upper side roller 40a of the rear feed roller 40 is lowered, thereby moving k paper to iK. After the paper reaches the other feed roller 39, The upper side m J ^ who paper and μ ^, the side 輮 39a is in a descending state, so the paper is transferred from the forward side 9 to the side, and the same side roller _ rises, and is moved by the rear feed roller 4: = 4 〇 k, the action of the A sheet ends. In addition, when the front end of the sheet is transferred to the contact point of the coating roller 22 of the reverse J-eight-view machine 21 and / ^ 25, by the operation mechanism 31! The cam 32 = 'the convex portion of the cam 仏 passes the cam 30 from the material 30 to swing the rod 29, 疋, raises the support roller 25, and passes the paper dust to the coating roller 22 through the belt 27. At the same time, the advancing to the upper side of the newspaper 39 is raised, so that the action of transferring the paper by the advancing roller 39 is finished. In the evening, again, before this, the front gauge 41 is raised so that the next paper is not transferred forward. In addition, since the frictional force of the above-mentioned belt 27 is large, the friction between the paper and the paper is greater than the friction between the paper and the coating material and the coating roller 22, so that the backup roller 25 rises and is separated by a belt. After the paper and the paper are pressed by the coating roller 22, the paper surface is transferred to the crucible by the rotation of the backup roller 25, and the coating roller 22 is coated. When the paper is transferred forward to a certain extent in this state, there is a phase difference in the direction of rotation, so that the cam follower 30 is transmitted to the convex portion 33a of the i-th cam 32, and at the rear end of the paper. When the portion reaches the contact point between the support roller 25 and the application roller 22, the 200920604 cam follower 30 is disengaged from the convex portion of the second cam 33, and the support 5 is rotated and lowered by gravity to cause the swing lever 29 to rotate and descend. After 22, the coating operation is completed. At this time, the front portion of the paper is placed on the conveyor belt, so that the support roller 25 is lowered and the conveyor belt 38 is driven immediately, thereby carrying out the paper. In addition, it is necessary to change the number according to the length of the paper and the change in the friction coefficient between the paper and the coating roller! The convex portion 33a of the cam 32 is engaged with the length of the convex portion 33a of the disk cam 33 in the circumferential direction. Therefore, by adjusting the second cam 33 with respect to the shaft 34, the convex portion 32a of the third cam is adjusted. The length of the & section 33 & overlap of the second cam 33 is changed. Moreover, when the second wheel 33 is rotated and rotated, it is preferable to use the case where the comet gear mechanism is used in the drive mechanism 35, and actually observe the applied and adjusted in the rotation process or set the front end of the detection paper in front. The department's organization to make adjustments. Further, the above-mentioned belt uses a belt having a width slightly narrower than the width of the coated paper so that the coating is not attached to the belt, and the belt of the appropriate width is appropriately replaced according to the width of the paper. In this creation, the paper feeding mechanism can be appropriately changed, for example, using a swing type of sweetness or a key bar, and the operating mechanism is not limited to the above-described embodiments.
