Description
本發明係關於一種介隔片材而抵壓於特定之對向輥之壓接輥、及此種壓接輥之製造方法。 The present invention relates to a pressure-bonding roller that presses a sheet against a specific counter roll, and a method of manufacturing such a pressure-bonding roll.
於製造塑料膜、塑料片材、織物等厚度比較薄之長條之物品(以下統稱為「片材」)之情形時，在各種步驟中，進行將作為原片、中間製品或製品之片材連續地送出之操作或拉取之操作。於此種操作中，藉由一面利用對向之2個輥夾持片材一面使該輥旋轉而送出/拉取片材，從而調整片材之移行速度及/或調整對片材施加之張力。典型而言，對向之1組輥係由軸被固定之導輥及夾輥構成。夾輥係壓接輥，其具有可動軸，且藉由對該可動軸施加之荷重而隔著片材被壓接於導輥。 When manufacturing a long strip of articles such as a plastic film, a plastic sheet, or a fabric (hereinafter collectively referred to as "sheet"), in various steps, a sheet to be used as an original sheet, an intermediate product, or a product is produced. The operation of continuously sending or pulling. In such an operation, the sheet is fed/pulled by rotating the sheet while holding the sheet by the opposing rolls, thereby adjusting the sheet moving speed and/or adjusting the tension applied to the sheet. . Typically, one set of rolls is opposed to a guide roll and a nip roll to which the shaft is fixed. The nip roll is a pressure roller which has a movable shaft and is pressed against the guide roller via a sheet by a load applied to the movable shaft.
關於此種輥之使用，以下列舉「切條步驟」為例進行說明。切條步驟係如下之步驟：自將寬幅之片材捲取成輥狀而成之中間製品(原片輥)捲出片材，並切開(切條)成特定之寬度，將已切開之各片材分別再次捲取成輥狀，由此獲得各寬度之複數個製品。於切條步驟中，使用被稱為切條機之裝置。該裝置包括自原片輥捲出片材之捲出部、將已捲出之片材切斷成特定寬度之切條部、及將已切斷成特定寬度之片材作為製品輥捲取之捲取部。於此種裝置中，存在為了防止捲出部之片材之張力變動傳播至切條部，而將與導輥一併夾持片材之夾輥配置於捲出部與切條部之間的情況。於此種情形時，要求夾輥對導 輥作用均勻之荷重。其理由係，若片材未被導輥與夾輥均勻地夾持，則有於切條部片材在寬度方向上蜿蜒，或於切條部片材產生破損之虞。 Regarding the use of such a roller, the following "cutting step" will be described as an example. The slitting step is a step of winding a sheet from an intermediate product (original sheet roll) obtained by winding a wide sheet into a roll shape, and cutting (cutting) into a specific width, which has been cut. Each of the sheets was again wound into a roll shape, thereby obtaining a plurality of articles of respective widths. In the slitting step, a device called a slitter is used. The apparatus includes a take-up portion for taking out a sheet from an original sheet roll, a cut portion for cutting the rolled sheet into a specific width, and a sheet which has been cut into a specific width as a product roll. Take-up department. In such an apparatus, in order to prevent the tension fluctuation of the sheet of the unwinding portion from being propagated to the slit portion, the nip roller that sandwiches the sheet together with the guide roller is disposed between the winding portion and the slit portion. Happening. In this case, the nip roller guide is required. The roller acts evenly. The reason is that if the sheet is not uniformly sandwiched between the guide roller and the nip roller, the sheet of the cut strip may be twisted in the width direction or may be damaged in the cut sheet.
因此，作為對導輥等對向輥作用均勻之荷重之壓接輥，提出有如下者。即，將中軸及外管隔開特定之間隔而雙層配置，於中央部將中軸及外管相互固定，藉此由中軸與外管使撓曲分離者(例如，參照日本專利實公平2-29076號公報、日本專利特開平2-66042號公報、日本專利特開平8-26535號公報、日本專利特開2004-277168號公報及日本專利特開2010-149983號公報)、將中軸及外管以特定之間隔雙重配置，經由複數個軸承連結中軸及外管，藉此由中軸與外管使撓曲分離者(例如，參照日本專利特公平6-45410號公報)。就該等壓接輥而言，係根據對向輥之撓曲而使外管撓曲，藉此對於對向輥作用均勻之荷重。 Therefore, as a pressure roller which applies a uniform load to a counter roller such as a guide roller, the following is proposed. In other words, the center shaft and the outer tube are arranged in a double layer at a predetermined interval, and the center shaft and the outer tube are fixed to each other at the center portion, whereby the center shaft and the outer tube are separated by deflection (for example, refer to Japanese Patent Fair 2 - Japanese Patent Laid-Open No. Hei 2-66042, Japanese Patent Laid-Open No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. The intermediate shaft and the outer tube are connected to each other via a plurality of bearings, whereby the central shaft and the outer tube are separated by deflection (for example, refer to Japanese Patent Publication No. Hei 6-45410). In the case of the crimping rolls, the outer tube is deflected according to the deflection of the opposing rolls, whereby a uniform load is applied to the opposing rolls.
此外，例如，自抑制旋轉中之振動之觀點而言，存在為了提高對向輥之固有振動數而提高對向輥之剛性的情況。於此種情形時，亦要求壓接輥對被高剛性化之對向輥作用均勻之荷重。 Further, for example, from the viewpoint of suppressing vibration during rotation, there is a case where the rigidity of the opposing roller is increased in order to increase the number of natural vibrations of the opposing roller. In this case, the pressure roller is also required to apply a uniform load to the highly rigid counter roller.
因此，本發明之目的在於提供一種能夠對被高剛性化之對向輥作用均勻之荷重之壓接輥、及此種壓接輥之製造方法。 Accordingly, an object of the present invention is to provide a pressure-bonding roller capable of applying a uniform load to a highly rigid counter roller, and a method of manufacturing such a pressure roller.
本發明之壓接輥係介隔片材而對特定之對向輥抵壓之壓接輥，其包括：中軸，其具有為圓柱面之外表面；及圓筒形狀之外管，其以具有與中軸相同之中心線之方式配置於中軸之外側，於與中心線平行之方向上之中軸之中央部與中軸接合。中軸包含具有190GPa以上且470GPa以下之縱向彈性模數之材料，外管包含具有100GPa以上且470GPa以下之縱向彈性模數之材料。中軸之外表面與外管之內表面之間隔成為外管之外徑×0.10mm以下。 The crimping roller of the present invention is a crimping roller that presses a sheet against a specific counter roller, and includes: a center shaft having a cylindrical outer surface; and a cylindrical outer tube having The center line of the same axis as the center axis is disposed on the outer side of the center axis, and the central portion of the shaft is engaged with the center shaft in a direction parallel to the center line. The center axis includes a material having a longitudinal elastic modulus of 190 GPa or more and 470 GPa or less, and the outer tube contains a material having a longitudinal elastic modulus of 100 GPa or more and 470 GPa or less. The distance between the outer surface of the center shaft and the inner surface of the outer tube becomes the outer diameter of the outer tube × 0.10 mm or less.
於該壓接輥中，中軸包含具有190GPa以上且470GPa以下之縱向彈性模數之材料，外管包含具有100GPa以上且470GPa以下之縱向彈性模數之材料。由此，能夠一面適當地提高中軸及外管之剛性，一面降低中軸及外管之撓曲量(於與中心線平行之方向之各位置之撓曲量之平均值)。進而，中軸之外表面與外管之內表面之間隔成為外管之外徑×0.10mm以下。由此，能夠降低中軸及外管之撓曲量以及外管之撓曲差(於與中心線平行之方向之各位置之撓曲量之最大值與最小值之差)。如上所述，根據該壓接輥，由於中軸及外管之撓曲量得以降低且外管之撓曲差得以降低，故而能夠對被高剛性化之對向輥作用均勻之荷重。 In the crimping roll, the center shaft contains a material having a longitudinal elastic modulus of 190 GPa or more and 470 GPa or less, and the outer tube contains a material having a longitudinal elastic modulus of 100 GPa or more and 470 GPa or less. Thereby, the amount of deflection of the center shaft and the outer tube (the average value of the amount of deflection at each position in the direction parallel to the center line) can be reduced while appropriately increasing the rigidity of the center shaft and the outer tube. Further, the distance between the outer surface of the intermediate shaft and the inner surface of the outer tube becomes the outer diameter of the outer tube × 0.10 mm or less. Thereby, the amount of deflection of the center shaft and the outer tube and the deflection difference of the outer tube (the difference between the maximum value and the minimum value of the deflection amount at each position in the direction parallel to the center line) can be reduced. As described above, according to the pressure roller, since the amount of deflection of the center shaft and the outer tube is lowered and the difference in deflection of the outer tube is lowered, it is possible to apply a uniform load to the counter roller which is highly rigid.
又，中軸之外表面與外管之內表面之間隔亦可成為外管之外徑×0.02mm以上。根據該構成，能夠防止中軸與外管接觸。 Further, the distance between the outer surface of the center shaft and the inner surface of the outer tube may be an outer diameter of the outer tube × 0.02 mm or more. According to this configuration, it is possible to prevent the center shaft from coming into contact with the outer tube.
又，中軸亦可為圓筒形狀之構件。根據該構成，能夠一面謀求壓接輥之輕量化，一面適當地降低中軸之撓曲量。 Further, the center shaft may be a cylindrical member. According to this configuration, it is possible to appropriately reduce the amount of deflection of the center axis while reducing the weight of the pressure roller.
又，中軸及外管之至少一者既可包含鋼，中軸及外管之至少一者亦可包含碳纖維強化樹脂。根據該等構成，能夠適當地降低中軸及外管之撓曲量，並且能夠適當地降低外管之撓曲差。 Further, at least one of the center shaft and the outer tube may include steel, and at least one of the center shaft and the outer tube may also contain a carbon fiber reinforced resin. According to these configurations, the amount of deflection of the center shaft and the outer tube can be appropriately reduced, and the deflection of the outer tube can be appropriately reduced.
又，壓接輥亦可作為與導輥即對向輥一併夾持片材之夾輥使用。根據該構成，能夠由導輥與夾輥均勻地夾持片材。由此，可防止例如於在切條機中在捲出部與切條部之間配置有導輥及夾輥之情形時，在切條部片材於寬度方向上蜿蜒，或於切條部片材產生破損。 Further, the pressure roller can also be used as a nip roller that sandwiches the sheet together with the guide roller, that is, the opposite roller. According to this configuration, the sheet can be uniformly held by the guide roller and the nip roller. Therefore, for example, when the guide roller and the nip roller are disposed between the winding portion and the slit portion in the slitter, the sheet is cut in the width direction or cut in the slit portion. The sheet was damaged.
又，壓接輥亦可進而包括形成於外管之外表面之鍍層。根據該構成，能夠抑制對片材造成損傷等。 Further, the pressure roller may further include a plating layer formed on the outer surface of the outer tube. According to this configuration, it is possible to suppress damage or the like to the sheet.
本發明之壓接輥之製造方法係上述壓接輥之製造方法，其包括如下步驟：準備被分割成兩半之外管；及使中軸之兩端部之各者***至被分割成兩半之外管之各者，於中軸之中央部，將被分割成兩半之 外管對接而與中軸接合。 The manufacturing method of the pressure-bonding roller of the present invention is the manufacturing method of the above-mentioned pressure-bonding roller, comprising the steps of: preparing a tube which is divided into two halves; and inserting each of both end portions of the central shaft into the two halves Each of the outer tubes will be split into two halves in the central part of the central axis. The outer tube is butted to engage the center shaft.
根據該壓接輥之製造方法，即使於將中軸之外表面與外管之內表面之間隔在外管之外徑×0.10mm以下之範圍內減小之情形時，亦可容易且高精度地製造具備在中央部被相互固定之中軸及外管之壓接輥。 According to the method of manufacturing the pressure-bonding roller, even when the distance between the outer surface of the intermediate shaft and the inner surface of the outer tube is reduced within the range of the outer diameter of the outer tube × 0.10 mm or less, the manufacturing can be easily and accurately performed. A pressure roller having a shaft and an outer tube fixed to each other at the center portion is provided.

以下，參照圖式詳細地說明本發明之較佳之實施形態。再者，於各圖中對相同或相當之部分標註相同之符號，並省略重複之說明。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and the repeated description is omitted.
圖1係應用有本發明之一實施形態之壓接輥之切條機之構成圖。如圖1所示，切條機10包括捲出部11、切條部12及捲取部13。捲出部11自原片輥R1捲出片材S。切條部12將由捲出部11捲出之片材S切斷成特定之寬度。捲取部13將已由切條部12切斷成特定寬度之片材S作為製品輥R2捲取。於切條機10中，片材S由複數個搬送輥14沿著特定之搬送路徑搬送。再者，片材S例如為塑料膜、積層膜、金屬箔、織物等。 Fig. 1 is a view showing the construction of a slitting machine to which a pressure roller according to an embodiment of the present invention is applied. As shown in FIG. 1, the slitter 10 includes a take-up portion 11, a slit portion 12, and a take-up portion 13. The winding portion 11 winds up the sheet S from the original sheet roll R1. The strip portion 12 cuts the sheet S taken up by the take-up portion 11 into a specific width. The take-up portion 13 takes up the sheet S that has been cut into a specific width by the slit portion 12 as a product roll R2. In the slitter 10, the sheet S is conveyed by a plurality of conveying rollers 14 along a specific conveying path. Further, the sheet S is, for example, a plastic film, a laminated film, a metal foil, a woven fabric or the like.
於捲出部11與切條部12之間的片材S之搬送路徑上，配置有作為導輥之對向輥15及壓接輥1。壓接輥1為與對向輥15一併夾持片材S之 夾輥。藉由該對向輥15及壓接輥1而防止於捲出部11之片材S之張力變動傳播至切條部12。再者，對向輥15例如包含鋁合金、鋼等金屬、使用高彈性碳纖維之碳纖維強化樹脂等具有60GPa以上且400GPa以下之縱向彈性模數之材料。 On the conveyance path of the sheet S between the unwinding portion 11 and the slit portion 12, a counter roller 15 and a pressure roller 1 as guide rollers are disposed. The pressure roller 1 is used to sandwich the sheet S together with the opposite roller 15 Clamping roller. By the opposing roller 15 and the pressure contact roller 1, the tension fluctuation of the sheet S of the unwinding portion 11 is prevented from being transmitted to the slit portion 12. In addition, the counter roller 15 includes a material having a longitudinal elastic modulus of 60 GPa or more and 400 GPa or less, such as a metal such as an aluminum alloy or steel, or a carbon fiber reinforced resin using a highly elastic carbon fiber.
於捲取部13設置有接觸輥16。接觸輥16介隔被捲取之片材S以特定之壓力接觸於製品輥R2之輥芯C。藉由該接觸輥16而防止空氣被捲入製品輥R2。再者，輥芯C例如包含鋁合金、鋼等金屬、使用高彈性碳纖維之碳纖維強化樹脂、塑料、紙等。 A contact roller 16 is provided in the winding portion 13. The contact roller 16 contacts the roll core C of the product roll R2 at a specific pressure through the wound sheet S. Air is prevented from being drawn into the product roll R2 by the contact roller 16. Further, the roll core C includes, for example, a metal such as an aluminum alloy or steel, a carbon fiber reinforced resin using a highly elastic carbon fiber, plastic, paper, or the like.
繼而，對介隔片材S抵壓於對向輥15之壓接輥1之構成進行說明。圖2係本發明之一實施形態之壓接輥之剖面圖。如圖2所示，壓接輥1包括圓筒形狀之中軸2、及以具有與中軸2相同之中心線L之方式配置於中軸2之外側之圓筒形狀之外管3。中軸2係具有圓柱面之外表面2a及內表面2b之圓筒形狀之構件。中軸2例如包含鋼等金屬、使用高彈性碳纖維之碳纖維強化樹脂等具有190GPa以上且470GPa以下之縱向彈性模數之材料。外管3係具有圓柱面之外表面3a及內表面3b之圓筒形狀之構件。外管3例如包含鋼等金屬、使用高彈性碳纖維之碳纖維強化樹脂等具有100GPa以上且470GPa以下之縱向彈性模數之材料。 Next, the configuration in which the spacer sheet S is pressed against the pressure roller 1 of the counter roller 15 will be described. Figure 2 is a cross-sectional view showing a pressure roller according to an embodiment of the present invention. As shown in FIG. 2, the pressure roller 1 includes a cylindrical outer shaft 2 and a cylindrical outer tube 3 disposed on the outer side of the intermediate shaft 2 so as to have the same center line L as the middle shaft 2. The center shaft 2 is a cylindrical member having a cylindrical outer surface 2a and an inner surface 2b. The center shaft 2 includes, for example, a metal such as steel or a carbon fiber reinforced resin using a highly elastic carbon fiber, and has a longitudinal elastic modulus of 190 GPa or more and 470 GPa or less. The outer tube 3 is a cylindrical member having a cylindrical outer surface 3a and an inner surface 3b. The outer tube 3 contains, for example, a metal such as steel or a carbon fiber reinforced resin using highly elastic carbon fibers, and has a longitudinal elastic modulus of 100 GPa or more and 470 GPa or less.
中軸2於與中心線L平行之方向之中央部2c經擴徑，且與外管3之內表面3b嵌合。於該狀態下，外管3藉由接著等而固定於中軸2之中央部2c。更詳細而言，外管3具有被分割成兩半之圓筒形狀之構件3c、3c。於中軸2之中央部2c，被分割成兩半之構件3c、3c以相互對接之狀態與中軸2接合。 The center shaft 2 is expanded in diameter at a central portion 2c in a direction parallel to the center line L, and is fitted to the inner surface 3b of the outer tube 3. In this state, the outer tube 3 is fixed to the central portion 2c of the center shaft 2 by being sequentially or the like. More specifically, the outer tube 3 has members 3c and 3c which are divided into two cylindrical shapes. In the central portion 2c of the center shaft 2, the members 3c and 3c divided into two halves are joined to the center shaft 2 in a state of being butted against each other.
中軸2之外表面2a(除中央部2c以外之部分之外表面)與外管3之內表面3b之間隔成為外管3之外徑×0.10mm以下。另一方面，中軸2之外表面2a與外管3之內表面3b之間隔成為外管3之外徑×0.02mm以上。如 此藉由在中軸2之外表面2a與外管3之內表面3b之間設置間隙，能夠以中軸2與外管3使撓曲分離。 The distance between the outer surface 2a of the intermediate shaft 2 (the surface other than the central portion 2c) and the inner surface 3b of the outer tube 3 becomes the outer diameter of the outer tube 3 × 0.10 mm or less. On the other hand, the distance between the outer surface 2a of the center shaft 2 and the inner surface 3b of the outer tube 3 becomes the outer diameter of the outer tube 3 × 0.02 mm or more. Such as By providing a gap between the outer surface 2a of the intermediate shaft 2 and the inner surface 3b of the outer tube 3, the central shaft 2 and the outer tube 3 can be separated from each other by deflection.
再者，成為中軸2與外管3之接合部之中央部2c之長度(以下僅稱為「長度」等情形時，係指與中心線L平行之方向上之長度)可設為外管3之長度之5~50%。由於該接合部之長度越小，越容易由中軸2與外管3分離撓曲，故而藉由對向輥15與壓接輥1對片材S之夾持之均勻性提高。但是，若該接合部之長度低於5%，則有因強度不足而壽命變短，或固有振動數下降之虞。相反，若該接合部之長度超過50%，則有由於不易由中軸2與外管3分離撓曲，故而藉由對向輥15與壓接輥1對片材S之夾持之均勻性變差之虞。 In addition, the length of the center portion 2c of the joint portion between the center shaft 2 and the outer tube 3 (hereinafter, simply referred to as "length" or the like, the length in the direction parallel to the center line L) can be set as the outer tube 3. 5 to 50% of the length. Since the length of the joint portion is smaller, it is easier to separate and deflect the center shaft 2 from the outer tube 3, so that the uniformity of the sandwiching of the sheet S by the opposing roller 15 and the pressure roller 1 is improved. However, if the length of the joint portion is less than 5%, the life is shortened due to insufficient strength, or the number of natural vibrations is lowered. On the other hand, if the length of the joint portion exceeds 50%, since the center shaft 2 is less likely to be separated from the outer tube 3, the uniformity of the sandwiching of the sheet S by the opposing roller 15 and the pressure roller 1 is changed. Poor.
進而，於中軸2之兩端部2d、2d之各者，固定有用於支持壓接輥1使之可繞中心線L自如旋轉之軸承4。又，於外管3之外表面3a，形成有例如包含銅、鎳、鉻、鐵、鋁等金屬之鍍層5。由此，能夠抑制對片材S造成損傷。再者，雖省略圖示，但存在於外管3之外表面3a被覆有橡膠或者橡膠狀彈性體之情況。 Further, a bearing 4 for supporting the pressure roller 1 so as to be rotatable around the center line L is fixed to each of the both end portions 2d and 2d of the center shaft 2. Further, a plating layer 5 containing a metal such as copper, nickel, chromium, iron or aluminum is formed on the outer surface 3a of the outer tube 3. Thereby, damage to the sheet S can be suppressed. Further, although not shown, the outer surface 3a of the outer tube 3 may be covered with a rubber or rubber-like elastic body.
如以上所說明般，於壓接輥1中，中軸2包含具有190GPa以上且470GPa以下之縱向彈性模數之材料，外管3包含具有100GPa以上且470GPa以下之縱向彈性模數之材料。較佳為，中軸2包含具有190GPa以上且350GPa以下之縱向彈性模數之材料，外管3包含具有120GPa以上且350GPa以下之縱向彈性模數之材料。由此，能夠一面適當地提高中軸2及外管3之剛性，一面降低中軸2及外管3之撓曲量(於與中心線L平行之方向之各位置之撓曲量之平均值)。進而，中軸2之外表面2a與外管3之內表面3b之間隔成為外管3之外徑×0.10mm以下。由此，能夠降低中軸2及外管3之撓曲量、以及外管3之撓曲差(於與中心線L平行之方向之各位置之撓曲量之最大值與最小值之差)。此處，外管3之撓曲差可藉由增大中軸2及外管3之至少一者之外徑或者增大 厚度而降低。如上所述，根據壓接輥1，中軸2及外管3之撓曲量得以降低且外管3之撓曲差得以降低。由此，能夠對以包含具有100GPa以上且470GPa以下之縱向彈性模數之材料之方式被高剛性化之對向輥15作用均勻之荷重。再者，只要將中軸2之外表面2a與外管3之內表面3b之間隔設為外管3之外徑×0.08mm以下，則能夠更進一步降低中軸2及外管3之撓曲量、以及外管3之撓曲差。 As described above, in the crimping roll 1, the center shaft 2 contains a material having a longitudinal elastic modulus of 190 GPa or more and 470 GPa or less, and the outer tube 3 contains a material having a longitudinal elastic modulus of 100 GPa or more and 470 GPa or less. Preferably, the center shaft 2 comprises a material having a longitudinal elastic modulus of 190 GPa or more and 350 GPa or less, and the outer tube 3 contains a material having a longitudinal elastic modulus of 120 GPa or more and 350 GPa or less. Thereby, the rigidity of the center shaft 2 and the outer tube 3 can be appropriately increased, and the amount of deflection of the center shaft 2 and the outer tube 3 (the average value of the amount of deflection at each position in the direction parallel to the center line L) can be reduced. Further, the distance between the outer surface 2a of the intermediate shaft 2 and the inner surface 3b of the outer tube 3 becomes the outer diameter of the outer tube 3 × 0.10 mm or less. Thereby, the amount of deflection of the center shaft 2 and the outer tube 3 and the deflection difference of the outer tube 3 (the difference between the maximum value and the minimum value of the deflection amount at each position in the direction parallel to the center line L) can be reduced. Here, the deflection difference of the outer tube 3 can be increased by increasing the outer diameter or increasing the at least one of the central shaft 2 and the outer tube 3. Reduced in thickness. As described above, according to the crimping roller 1, the amount of deflection of the center shaft 2 and the outer tube 3 is lowered and the deflection difference of the outer tube 3 is lowered. Thereby, it is possible to apply a uniform load to the counter roller 15 which is highly rigid so as to include a material having a longitudinal elastic modulus of 100 GPa or more and 470 GPa or less. In addition, if the distance between the outer surface 2a of the intermediate shaft 2 and the inner surface 3b of the outer tube 3 is set to the outer diameter of the outer tube 3 × 0.08 mm or less, the amount of deflection of the middle shaft 2 and the outer tube 3 can be further reduced, And the deflection difference of the outer tube 3.
又，於壓接輥1中，中軸2之外表面2a與外管3之內表面3b之間隔成為外管3之外徑×0.02mm以上。由此，能夠防止因中軸2及外管3撓曲而導致中軸2與外管3接觸。又，壓接輥1之製造亦變得容易。 Further, in the pressure roller 1, the distance between the outer surface 2a of the intermediate shaft 2 and the inner surface 3b of the outer tube 3 becomes the outer diameter of the outer tube 3 × 0.02 mm or more. Thereby, it is possible to prevent the intermediate shaft 2 from coming into contact with the outer tube 3 due to the deflection of the intermediate shaft 2 and the outer tube 3. Moreover, the manufacture of the pressure roller 1 is also easy.
又，壓接輥1作為與作為導輥之對向輥15一併夾持片材S之夾輥使用。於此情形時，在切條機10中，能夠由對向輥15與壓接輥1均勻地夾持片材S。由此，能夠防止在切條部12片材S於寬度方向上蜿蜒、或於切條部12片材S產生破損。 Further, the pressure roller 1 is used as a nip roller that sandwiches the sheet S together with the opposite roller 15 as a guide roller. In this case, in the slitter 10, the sheet S can be uniformly sandwiched by the opposing roller 15 and the pressure roller 1. Thereby, it is possible to prevent the sheet S in the slit portion 12 from being twisted in the width direction or the sheet S in the cut portion 12 from being damaged.
此處，對於作為夾輥使用之壓接輥1，要求以下之第1~4點。 Here, the following first to fourth points are required for the pressure roller 1 used as the nip roller.
第1點係壓接輥1遍及片材S之寬度方向之全部範圍地密接於對向輥15上之片材S，並且對片材S產生均勻之夾持力(對向輥15及壓接輥1夾持片材S之力)。其理由係，若於與中心線L平行之方向之壓接輥1之任一位置未產生均勻之夾持力，則有於製品輥R2中捲入片材S之間之空氣量產生不均勻而導致各種捲取缺點之虞。 The first point is that the pressure roller 1 is in close contact with the sheet S on the opposite roller 15 over the entire width direction of the sheet S, and produces a uniform clamping force against the sheet S (opposite roller 15 and crimping) The roller 1 holds the force of the sheet S). The reason is that if a uniform holding force is not generated at any position of the pressure roller 1 in the direction parallel to the center line L, the amount of air interposed between the sheets S in the product roll R2 is uneven. This leads to the shortcomings of various windings.
第2點係壓接輥1之撓曲較小。其理由係，於壓接輥1介隔片材S抵壓於對向輥15時，若壓接輥1撓曲，則有對於對向輥15作用較所期望之荷重小之荷重，而無法獲得壓接輥1之性能之虞。 The second point is that the deflection of the pressure roller 1 is small. The reason is that when the pressure roller 1 presses the sheet S against the counter roller 15, when the pressure roller 1 is deflected, the load on the counter roller 15 is less than the desired load, and it is impossible to The performance of the pressure roller 1 is obtained.
第3點係壓接輥1之高速性能優異。即，第3點係壓接輥1之固有振動數(容許速度)較高。其理由係，若壓接輥1之固有振動數較低，則有壓接輥1於自身旋轉過程中振動之虞。 The third point is that the pressure roller 1 is excellent in high speed performance. In other words, the number of natural vibrations (allowable speed) of the third-point pressure-bonding roller 1 is high. The reason is that if the natural vibration number of the pressure roller 1 is low, there is a possibility that the pressure roller 1 vibrates during its own rotation.
第4點係壓接輥1之製造成本較低。其理由係，通常，應準備之 夾輥之種類或數量較其他輥多。 The fourth point is that the crimping roll 1 is low in manufacturing cost. The reason is usually, should be prepared There are more types or quantities of nip rolls than other rolls.
根據上述壓接輥1，由於中軸2及外管3之撓曲量得以降低且外管3之撓曲差得以降低，故而滿足第1點及第2點。 According to the pressure roller 1 described above, since the amount of deflection of the center shaft 2 and the outer tube 3 is lowered and the deflection difference of the outer tube 3 is lowered, the first point and the second point are satisfied.
又，由於中軸2及外管3被高剛性化，故而固有振動數提高，其結果，亦滿足第3點。尤其於中軸2及外管3包含碳纖維強化樹脂之情形時，由於中軸2及外管3被輕量化，故而能夠進一步提高固有振動數。但是，若中軸2及外管3之至少一者包含碳纖維強化樹脂，則能夠適當地降低中軸2及外管3之撓曲量，並且能夠適當地降低外管3之撓曲差。 Further, since the center shaft 2 and the outer tube 3 are highly rigid, the number of natural vibrations is improved, and as a result, the third point is also satisfied. In particular, when the middle shaft 2 and the outer tube 3 contain a carbon fiber reinforced resin, since the center shaft 2 and the outer tube 3 are reduced in weight, the number of natural vibrations can be further increased. However, when at least one of the center shaft 2 and the outer tube 3 includes the carbon fiber reinforced resin, the amount of deflection of the center shaft 2 and the outer tube 3 can be appropriately reduced, and the deflection difference of the outer tube 3 can be appropriately reduced.
進而，由於壓接輥1之構成被簡化，故而亦滿足第4點。尤其於中軸2及外管3包含鋼之情形時，由於中軸2及外管3之材料之成本變低，故而能夠謀求壓接輥1自身之低成本化。但是，若中軸2及外管3之至少一者包含鋼，則能夠適當地降低中軸2及外管3之撓曲量，並且能夠適當地降低外管3之撓曲差。 Further, since the configuration of the pressure roller 1 is simplified, the fourth point is also satisfied. In particular, when the center shaft 2 and the outer tube 3 contain steel, since the cost of the material of the center shaft 2 and the outer tube 3 is low, the cost of the pressure roller 1 itself can be reduced. However, if at least one of the center shaft 2 and the outer tube 3 contains steel, the amount of deflection of the center shaft 2 and the outer tube 3 can be appropriately reduced, and the deflection difference of the outer tube 3 can be appropriately reduced.
繼而，對上述壓接輥1之製造方法進行說明。首先，準備被分割成兩半之外管3(即，構件3c、3c)。接下來，使中軸2之兩端部2d、2d之各者***至被分割成兩半之外管3之各者，於中軸2之中央部2c將被分割成兩半之外管3對接。然後，藉由在該狀態下，利用接著等將外管3固定於中軸2之中央部2c，而於中軸2之中央部2c將被分割成兩半之外管3與中軸2接合。 Next, a method of manufacturing the above-described pressure roller 1 will be described. First, the tube 3 (i.e., the members 3c, 3c) is prepared to be divided into two halves. Next, each of the both end portions 2d and 2d of the center shaft 2 is inserted into each of the tubes 3 divided into two halves, and the tube 3 is butted in the center portion 2c of the center shaft 2 to be divided into two halves. Then, in this state, the outer tube 3 is fixed to the central portion 2c of the intermediate shaft 2 by the following, and the central portion 2c of the intermediate shaft 2 is divided into two halves, and the tube 3 is joined to the intermediate shaft 2 by the second portion.
根據該壓接輥1之製造方法，即使於將中軸2之外表面2a與外管3之內表面3b之間隔在外管3之外徑×0.10mm以下之範圍內減小之情形時，亦可容易且精度良好地製造包括在中央部2c被相互固定之中軸2及外管3之壓接輥1。更具體而言，由於中軸2及外管3容易定芯，故而能夠製造偏芯較小之壓接輥1。又，由於芯骨(中軸2)之撓曲較小，故而能夠製造精度良好之壓接輥1。 According to the manufacturing method of the pressure roller 1, even when the interval between the outer surface 2a of the intermediate shaft 2 and the inner surface 3b of the outer tube 3 is reduced within the range of the outer diameter of the outer tube 3 × 0.10 mm or less, The pressure roller 1 including the shaft 2 and the outer tube 3 which are fixed to each other in the center portion 2c is easily and accurately manufactured. More specifically, since the center shaft 2 and the outer tube 3 are easily centered, it is possible to manufacture the pressure roller 1 having a small eccentricity. Further, since the deflection of the core metal (the center shaft 2) is small, the pressure-sensitive adhesive roll 1 having high precision can be manufactured.
又，於壓接輥1中，由於中軸2之外表面2a與外管3之內表面3b之間隔成為外管之外徑×0.02mm以上，故而能夠使中軸2之兩端部2d、2d之各者容易地***至被分割成兩半之外管3之各者。 Further, in the pressure-bonding roller 1, since the outer surface 2a of the intermediate shaft 2 and the inner surface 3b of the outer tube 3 are spaced apart from each other by the outer diameter of the outer tube × 0.02 mm or more, the both end portions 2d and 2d of the intermediate shaft 2 can be made. Each is easily inserted into each of the tubes 3 that are divided into two halves.
以上，對本發明之一實施形態進行了說明，但本發明並不限定於上述實施形態。例如，中軸2並不限定於圓筒形狀之構件，亦可為實心圓柱形狀之構件。但是，若中軸2為圓筒形狀之構件，則能夠一面謀求壓接輥1之輕量化，一面適當地降低中軸2之撓曲量。又，壓接輥1並不限定於作為與作為導輥之對向輥15一併夾持片材S之夾輥使用。壓接輥1例如亦可使用於上述切條機10之接觸輥16等其他用途。 Although an embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, the center shaft 2 is not limited to a member having a cylindrical shape, and may be a member having a solid cylindrical shape. However, when the center shaft 2 is a cylindrical member, the amount of deflection of the center shaft 2 can be appropriately reduced while reducing the weight of the pressure roller 1 . Further, the pressure roller 1 is not limited to use as a nip roller that sandwiches the sheet S together with the opposite roller 15 as a guide roller. The pressure roller 1 can be used, for example, in other applications such as the contact roller 16 of the above-described slitter 10.
於上述中，主要對切條步驟之例進行了說明，但本發明之壓接輥於處理片材之其他各種步驟中亦可較佳地使用。即，藉由本發明之壓接輥擔負對與該壓接輥對向之輥施加之均勻之壓接，而可穩定地處理片材。 In the above, the example of the slitting step has been mainly described, but the crimping roller of the present invention can also be preferably used in other various steps of processing the sheet. That is, the sheet can be stably processed by the pressure roller of the present invention which is subjected to uniform pressure contact applied to the roller opposed to the pressure roller.
作為其他例，可列舉將片材相對於移行方向延伸之延伸步驟。延伸步驟係用於製造延伸片材之步驟。於延伸步驟中，自上游向下游依序配置：將自原片輥捲出原片片材之捲出部、夾持被捲出之片材之第1夾輥/導輥、加熱片材之機構(熱板、烘箱等)、夾持片材之第2夾輥/導輥、及捲取經延伸之片材之捲取部。根據第2夾輥/導輥之周速度相對於第1夾輥/導輥之周速度之比，於加熱片材之機構中將片材於移行方向上延伸。藉由將本發明之壓接輥用於第1及/或第2夾輥，可擔負片材之寬度方向上之均勻之壓接。由此，能夠抑制片材之蜿蜒或局部之滑動等，而能夠實現片材之相對於寬度方向及移行方向均勻之延伸。 As another example, an extending step of extending the sheet with respect to the traveling direction can be cited. The stretching step is a step for making an extended sheet. In the extending step, sequentially from the upstream to the downstream: the unwinding portion of the original sheet is rolled out from the original sheet, the first nip/guide roller that holds the unwound sheet, and the heated sheet A mechanism (hot plate, oven, etc.), a second nip roller/guide roller for holding the sheet, and a take-up portion for taking up the stretched sheet. The sheet is stretched in the traveling direction in the mechanism for heating the sheet in accordance with the ratio of the peripheral speed of the second nip/guide roller to the peripheral speed of the first nip/guide roller. By using the pressure roller of the present invention for the first and/or second nip rolls, uniform pressure bonding in the width direction of the sheet can be carried out. Thereby, it is possible to suppress the sliding of the sheet or the partial sliding of the sheet, and it is possible to achieve uniform extension of the sheet with respect to the width direction and the traveling direction.
又，作為進而其他例，可列舉對片材進行印刷之印刷步驟、藉由接著劑貼合複數種片材之貼合(乾式層壓)步驟等。藉由在該等步驟中將本發明之壓接輥例如用作為夾輥，而能夠抑制片材之蜿蜒，獲得 穩定之移行速度及均勻且穩定之張力。由此，於印刷步驟中，能夠進行精細且穩定之印刷。又，於貼合步驟中，能夠獲得均勻且穩定之接著力。 Further, as another example, a printing step of printing a sheet, a lamination (dry lamination) step of laminating a plurality of sheets by an adhesive, and the like may be mentioned. By using the pressure roller of the present invention as a nip roller in these steps, for example, it is possible to suppress the flaw of the sheet and obtain Stable travel speed and uniform and stable tension. Thereby, fine and stable printing can be performed in the printing step. Further, in the bonding step, a uniform and stable adhesive force can be obtained.
以下，藉由實施例更具體地說明本發明。但是，本發明並不限定於以下之實施例。 Hereinafter, the present invention will be more specifically described by way of examples. However, the invention is not limited to the following examples.
以表1所示之條件準備實施例1~4及比較例1、2之壓接輥，使200kgf(=1.96kN)之等分佈荷重(uniformly distributed load)作用於各壓接輥之全長。由此，進行將各壓接輥作為夾輥使用時之評價試驗(模擬)。於實施例1~4及比較例1、2中，壓接輥(外管)之長度為3200mm，外管及中軸之材質係縱向彈性模數為294.2GPa之CFRP(碳纖維強化樹脂)。再者，於表1中，所謂間隙係指中軸之外表面與外管之內表面之間隔，所謂接合長度係指於中軸之中央部之中軸與外管之接合部之長度(於表2及表3中亦相同)。 The pressure-bonding rolls of Examples 1 to 4 and Comparative Examples 1 and 2 were prepared under the conditions shown in Table 1, and a uniformly distributed load of 200 kgf (=1.96 kN) was applied to the entire length of each of the pressure-bonding rolls. Thus, an evaluation test (simulation) when each of the pressure-bonding rolls was used as a nip roll was performed. In Examples 1 to 4 and Comparative Examples 1 and 2, the length of the pressure-bonding roll (outer tube) was 3,200 mm, and the material of the outer tube and the center shaft was CFRP (carbon fiber reinforced resin) having a longitudinal elastic modulus of 294.2 GPa. In addition, in Table 1, the gap means the distance between the outer surface of the central axis and the inner surface of the outer tube, and the joint length means the length of the joint between the shaft and the outer tube in the central portion of the central axis (see Table 2 and The same is true in Table 3.)
如表1及圖3所示，使間隙越小，撓曲量及撓曲差越被降低，於實施例1~4及比較例1之壓接輥中，撓曲量低於1.6mm，撓曲差低於0.07mm。但是，若間隙成為1mm以下，則壓接輥之製造變得困難，故而比較例1之壓接輥不現實。自該結果而言，間隙較佳為外管之外徑×0.10mm以下(實施例1~4)，更佳為外管之外徑×0.08mm以下(實施例1~3)。另一方面，可謂間隙較佳為外管之外徑×0.02mm以上(實施例1~4)。 As shown in Table 1 and FIG. 3, the smaller the gap is, the more the deflection amount and the deflection difference are reduced. In the pressure-bonding rolls of Examples 1 to 4 and Comparative Example 1, the deflection amount is less than 1.6 mm, and the deflection is performed. The difference is less than 0.07 mm. However, when the gap is 1 mm or less, the production of the pressure roller becomes difficult, and thus the pressure roller of Comparative Example 1 is not practical. From the results, the gap is preferably the outer diameter of the outer tube × 0.10 mm or less (Examples 1 to 4), and more preferably the outer diameter of the outer tube × 0.08 mm or less (Examples 1 to 3). On the other hand, the gap is preferably an outer diameter of the outer tube × 0.02 mm or more (Examples 1 to 4).
繼而，以表2所示之條件準備實施例5~10之壓接輥，使200kgf(=1.96kN)之等分佈荷重作用於各壓接輥之全長。由此，進行將各壓接輥作為夾輥使用時之評價試驗(模擬)。於實施例5~10中，壓接輥(外管)之長度為3200mm。於實施例5及實施例6中，外管及中軸之材質使用具有互不相同之縱向彈性模數之CFRP。又，於實施例7~10中，變更了中軸之厚度。 Then, the pressure-bonding rolls of Examples 5 to 10 were prepared under the conditions shown in Table 2, and an equal-distribution load of 200 kgf (=1.96 kN) was applied to the entire length of each of the pressure-bonding rolls. Thus, an evaluation test (simulation) when each of the pressure-bonding rolls was used as a nip roll was performed. In Examples 5 to 10, the length of the crimping roll (outer tube) was 3,200 mm. In the fifth embodiment and the sixth embodiment, the material of the outer tube and the middle shaft is CFRP having mutually different longitudinal elastic modulus. Further, in Examples 7 to 10, the thickness of the center axis was changed.
如表2及圖4所示，藉由增大中軸及外管之材質之縱向彈性模數，而降低了撓曲差。此處，若著眼於圖4之實施例6之圖，則與中軸與外管之接合部之撓曲差相比，該接合部之兩側之部分之撓曲差變大。為了降低中軸與外管之接合部之撓曲差，而必須降低中軸之撓曲量。因此，如實施例7~10般，藉由增大中軸之內徑及外徑，撓曲差被降低至0.031mm。 As shown in Table 2 and Figure 4, the deflection difference is reduced by increasing the longitudinal elastic modulus of the material of the center shaft and the outer tube. Here, focusing on the map of the sixth embodiment of Fig. 4, the difference in deflection between the both sides of the joint portion is larger than the difference in the deflection of the joint portion between the center shaft and the outer tube. In order to reduce the deflection difference between the joint portion of the center shaft and the outer tube, it is necessary to reduce the amount of deflection of the center shaft. Therefore, as in the case of Examples 7 to 10, the deflection difference was reduced to 0.031 mm by increasing the inner diameter and the outer diameter of the center axis.
繼而，以表3所示之條件準備實施例11~18之壓接輥，使200kgf(=1.96kN)之等分佈荷重作用於各壓接輥之全長。由此，進行將各壓接輥作為夾輥使用時之評價試驗(模擬)。於實施例11~18中，壓接輥(外管)之長度為2500mm。於實施例11及實施例12中，外管及中軸之材質使用具有互不相同之縱向彈性模數之CFRP。又，於實施例13~15中，變更了中軸之厚度，於實施例16~18中，變更了外管之厚度。 Then, the pressure-bonding rolls of Examples 11 to 18 were prepared under the conditions shown in Table 3, and an equal-distribution load of 200 kgf (=1.96 kN) was applied to the entire length of each of the pressure-bonding rolls. Thus, an evaluation test (simulation) when each of the pressure-bonding rolls was used as a nip roll was performed. In Examples 11 to 18, the length of the pressure roller (outer tube) was 2,500 mm. In the eleventh embodiment and the twelfth embodiment, the material of the outer tube and the middle shaft is CFRP having mutually different longitudinal elastic modulus. Further, in Examples 13 to 15, the thickness of the center axis was changed, and in Examples 16 to 18, the thickness of the outer tube was changed.
如表3及圖5所示，藉由增大中軸及外管之材質之縱向彈性模數，而降低了撓曲差。又，可知此情形雖增大外管之厚度，但於降低撓曲量及撓曲差之方面有效。 As shown in Table 3 and Figure 5, the deflection difference is reduced by increasing the longitudinal elastic modulus of the material of the center shaft and the outer tube. Moreover, it is understood that the thickness of the outer tube is increased in this case, but it is effective in reducing the amount of deflection and the difference in deflection.
根據本發明，可提供一種能夠對被高剛性化之對向輥作用均勻之荷重之壓接輥、及此種壓接輥之製造方法。 According to the present invention, it is possible to provide a pressure-bonding roller capable of applying a uniform load to a highly rigid counter roller, and a method of manufacturing such a pressure roller.
