The treatment is usually carried out by electro-mine processing, groove processing, or de-glossing, so that the sheet can be reliably conveyed. As described above, the guide roller of the smooth electric ore processing is applied as a whole, and as the conveying rate of the sheet is increased, an air layer is generated between the sheet and the guide roller, resulting in a small frictional force. Therefore, the guide roller is liable to slip relative to the sheet, and if the sheet and the guide stick are slipped, there is a problem that scratches are generated on the sheet. Accordingly, in order to eliminate the air layer, for the purpose of lifting the sheet and guiding the grip, the entire guide roller is grooved to reduce the slippage between the sheet and the guide roller. Therefore, it is possible to increase the problem of the occurrence of wrinkles due to the deformation of the groove processing or the gloss-removing process Z, and the type of guide roller, which may be caused by the device and the sheet. The subject provides _ to prevent slippage between the sheet and the guide, while preventing wrinkles caused by the relative deformation between 200925537.

[發明概要] 本發明係一種用來引導行進之薄片的導輥，其係僅將 5 前述導輥之中央部的表面施以相對前述薄片之止滑加工， 前述中央部以外之兩側部表面為平滑之導粮。 根據本發明，因只將導輥表面之中央部份施以止滑加 工，使中央部份的摩擦力變大，薄片與導輥的旋轉方向之 滑移減少。另一方面，因於導輥兩側部是平滑的狀態，故 10 摩擦力變小，故可防止發生有因裝置與薄片之間相對地變 形所造成的皺折。 [圖式簡單說明] 第1圖係本發明的一種實施態樣中用導輥輸送薄片之 說明圖。 15 第2圖係本實施態樣的導輥之平面圖。 第3圖係變更例1的導輥之平面圖。 第4圖係變更例2的導輥之平面圖。 第5圖係變更例3的導輥之平面圖。 第6圖係變更例4的導輥之平面圖。 20 【實施方式】 [較佳實施例之詳細說明] 以下，關於本發明之一種實施態樣的導輥10，是根據 第1圖與第2圖加以說明。 本實施態樣的導輥10，如第1圖所示，係用以輸送紙、 200925537 布帛、金屬箔、底片等薄片W之導輥10，導輥10本身係不 驅動，而是藉薄片w之力旋轉的他動式。 (1) 導輥10之構成 如第2圖所示，導輥10係有軸14從圓柱狀之滚筒本體的兩 5 端部突出。 於該滚筒本體12的中央部16設有螺旋狀的溝槽，進行 止滑加工。該中央部16的長度Μ，若以滾筒本體12的全長 為L，則Μ對L為20〜70%，而以40〜60%為佳。又，中央 〇 部16以外之兩側部18施以平滑電鑛加工。 1〇 該導輥1〇之材質係經樹脂浸潰之碳纖維或為金屬製 者。又，該導親10直徑為70〜2〇〇mm(以lOnim〜150mm為佳）， 全長為250刪〜5m(以1.5〜3m為佳）。 (2) 效果 如上述導親10 ’藉中央部16之止滑加工，導輥10與薄 15片W之間的空氣層消失’摩擦力上升，導輥1〇與薄片W之 間不產生滑移，薄片W不會受傷。 ® 又，導輥10的兩側部18，因施有平滑電鍍加工，該部 • 分的摩擦力變小，即使薄片W或輸送該薄片W之裝置有變 形，因兩側部18的摩擦力小而在幅方向上錯開，不會發生 20 有因變形而導致之皺折。 (3)變更例 本發明不受限於上述各實施態樣，只要不脫離該主旨 則可作各種變更。 上述實細*癌樣中作為止滑加工，雖於中央部16設有螺 200925537 旋狀溝槽，亦可如第3圖所示之平行溝槽、如第4圖所示之 與中央部作對稱的螺旋狀溝槽、如第5圖所示之格子狀溝 槽、如第6圖所示之去光澤加工。 t圖式簡單說明3 5 第1圖係本發明的一種實施態樣中用導輥輸送薄片之 說明圖。 第2圖係本實施態樣的導輥之平面圖。 第3圖係變更例1的導輥之平面圖。 第4圖係變更例2的導輥之平面圖。 10 第5圖係變更例3的導輥之平面圖。 第6圖係變更例4的導輥之平面圖。 【主要元件符號說明】 10.........導輥 12.........滚筒本體 14.........軸 16.........中央部 18.........兩側部 W.........薄片 L..........滚筒本體全長 Μ.........中央部長度[Summary of the Invention] The present invention is a guide roller for guiding a traveling sheet, which applies only a surface of a central portion of the aforementioned guide roller to a slip-slip processing of the sheet, and a surface of both sides other than the central portion. For smoothing the food guide. According to the present invention, since only the central portion of the surface of the guide roller is subjected to the anti-slip processing, the frictional force of the central portion is increased, and the slip of the direction of rotation of the sheet and the guide roller is reduced. On the other hand, since both side portions of the guide roller are in a smooth state, the frictional force is reduced, so that wrinkles caused by the relative deformation between the device and the sheet can be prevented.

Fig. 3 is a plan view showing a guide roller of Modification 1. Fig. 4 is a plan view showing a guide roller of Modification 2. Fig. 5 is a plan view showing a guide roller of Modification 3. Fig. 6 is a plan view showing a guide roller of Modification 4. [Embodiment] [Detailed Description of Preferred Embodiments] Hereinafter, a guide roller 10 according to an embodiment of the present invention will be described with reference to Figs. 1 and 2 . The guide roller 10 of the present embodiment, as shown in Fig. 1, is used for conveying the guide roller 10 of paper, 200925537 fabric, metal foil, negative film, etc., and the guide roller 10 itself is not driven, but by the sheet w The force of his rotation. (1) Configuration of the guide roller 10 As shown in Fig. 2, the guide roller 10 has a shaft 14 projecting from both end portions of the cylindrical drum main body. A spiral groove is formed in the central portion 16 of the drum main body 12 to perform the anti-slip processing. When the length of the central portion 16 is Μ, if the entire length of the drum main body 12 is L, the Μ pair L is 20 to 70%, and preferably 40 to 60%. Further, the both side portions 18 other than the central portion 16 are subjected to smooth electric ore processing. 1〇 The material of the guide roller 1〇 is made of resin-impregnated carbon fiber or made of metal. Further, the guide 10 has a diameter of 70 to 2 mm (preferably, lOnim to 150 mm), and the total length is 250 to 5 m (preferably 1.5 to 3 m). (2) The effect is as follows: the sliding of the central portion 16 by the guide member 10', the air layer between the guide roller 10 and the thin 15 sheet W disappears, the frictional force rises, and the guide roller 1〇 and the sheet W do not slip. Move, the sheet W will not be injured. Further, since the both side portions 18 of the guide roller 10 are subjected to smooth plating processing, the frictional force of the portion is reduced, and even if the sheet W or the device for transporting the sheet W is deformed, the friction of the both side portions 18 is caused. Small and staggered in the direction of the web, there will be no wrinkles caused by deformation. (3) Modifications The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit and scope of the invention. In the above-mentioned solid *cancellous sample, as the anti-slip processing, although the central portion 16 is provided with a spiral groove of 200925537, it may be a parallel groove as shown in Fig. 3, as shown in Fig. 4 and the central portion. A symmetrical spiral groove, a lattice-like groove as shown in Fig. 5, and a matte finish as shown in Fig. 6.
