Description
本發明係有關一種拉伸裝置及夾具個數調整方法。The invention relates to a stretching device and a method for adjusting the number of clamps.
在日本專利公開公報特開2012-121259號中,揭露一種具備無端連結(endless link)裝置的雙軸同時拉伸裝置,前述無端連結裝置在片狀物的兩側具備抓持片狀物端部的複數個抓緊裝置。Japanese Patent Laid-Open Publication No. 2012-121259 discloses a biaxial simultaneous stretching device provided with an endless link device, wherein the endless link device is provided with end portions for gripping the sheet on both sides of the sheet a plurality of grasping devices.
此無端連結裝置係在拉伸區間中,由配置為在行進方向呈末端展開狀而並排的2支引導用導軌所引導,在TD方向(末端展開狀部分的縱向)拉伸的同時,關於MD方向(行進方向)抓緊間距從P1至P2逐漸擴大。藉此,使片狀物在縱橫兩方向同時拉伸。無端連結裝置係以藉由出口側鏈輪所驅動、且返回至入口側鏈輪的方式所構成。This endless linking device is guided by two guide rails arranged to be arranged side by side in the running direction in a terminally developed shape in the stretching section. The direction (travel direction) gripping pitch gradually expands from P1 to P2. Thereby, the sheet-like object is simultaneously stretched in both the vertical and horizontal directions. The endless connection device is driven by the sprocket on the outlet side and is configured to return to the sprocket on the inlet side.
在日本專利公開公報特開2012-121259號所記載的拉伸裝置中,無端連結裝置係藉由複數個輥引導沿導軌的移動。另外,無端連結裝置係藉由複數個連結機構所構成,藉由改變兩個導軌的間隔使在MD方向的抓緊裝置(夾具單元)的間距改變,從而使薄膜(片狀物)在MD方向拉伸。In the stretching device described in Japanese Patent Laid-Open Publication No. 2012-121259, the endless connecting device guides the movement along the guide rail by a plurality of rollers. In addition, the endless linking device is composed of a plurality of linking mechanisms, and by changing the distance between the two guide rails to change the distance between the gripping devices (clamp units) in the MD direction, the film (sheet) is pulled in the MD direction. stretch.
在此種拉伸裝置中,尋求一種能夠適當調整夾具單元之個數的拉伸裝置,前述夾具單元在拉伸薄膜的拉伸區域。例如,在拉伸區域的夾具單元的個數較適當的個數更少的狀態下,在連接夾具單元彼此的連結機構中,施加擴大夾具單元的間距之方向的力。藉由此力,設於夾具單元的輥,對導軌往單一方向推壓。當從輥向導軌作用的負荷過大時,會有產生軌道裝置或夾具單元的變形等之虞。為了避免此種事態,有必要適當調整拉伸區域的夾具單元的個數。In such a stretching device, a stretching device capable of appropriately adjusting the number of clip units in the stretching region of the stretched film is sought. For example, in a state in which the number of clip units in the stretching region is smaller than an appropriate number, a force in a direction of increasing the pitch of the clip units is applied to the connection mechanism for connecting the clip units. With this force, the roller provided in the jig unit presses the guide rail in one direction. When the load acting on the guide rail from the roller is too large, there is a possibility that the rail device or the clamp unit may be deformed. In order to avoid such a situation, it is necessary to appropriately adjust the number of clamp units in the stretching area.

夾具把持部30,係分別把持夾具20,並存在與夾具20的個數相同的個數。夾具把持部30,係為藉由上樑35、下樑36、前壁37、後壁38所形成的封閉截面之堅固的框架結構。在夾具把持部30的兩端(前壁37、後壁38)分別藉由軸31、32使傳動輪33、34設置為可旋轉。傳動輪33、34,在軌道台110所形成的水平之運行路面111、112上轉動。運行路面111、112遍布整個區域地並列於軌道裝置10L、10R的基準軌11。The

另外,如圖1所示,在拉伸裝置100的出口部分,設有作為個數計測部的計數感測器81,前述計數感測器81用以計測薄膜搬運區TA內之夾具20的個數(以下亦簡稱為「夾具個數」)。將計數感測器81的計測結果輸入至控制器80,根據夾具單元CU的移動速度與計數感測器81的計測結果,計算夾具個數。換言之,夾具個數係表示拉伸薄膜時實際抓持薄膜的左右之單側的夾具20(夾具單元CU)的個數。進一步從別的觀點言之,夾具個數係表示從入口側鏈輪61L、61R往出口側鏈輪62L、62R的前進路線上,拉伸裝置100的入口與出口之間的夾具20的個數。In addition, as shown in FIG. 1 , at the exit portion of the stretching

首先,針對由拉伸裝置100所為的薄膜拉伸方法進行說明。First, the film stretching method by the stretching
分別旋轉驅動左側的出口側鏈輪62L與右側的出口側鏈輪62R,前述左側的出口側鏈輪62L藉由第1驅動馬達64L向逆時針方向旋轉,前述右側的出口側鏈輪62R藉由第2驅動馬達64R向順時針方向旋轉。另外,藉由第3驅動馬達65,分別旋轉驅動右側的入口側鏈輪61R與左側的入口側鏈輪61L,前述右側的入口側鏈輪61R向順時針方向旋轉,前述左側的入口側鏈輪61L向逆時針方向旋轉。使左右的出口側鏈輪62L、62R與入口側鏈輪61L、61R相互以相同的旋轉速度旋轉驅動。藉由將驅動輥58卡合於此等鏈輪,從而將運行力賦予至夾具把持部30。藉此,夾具單元CU,在右側巡迴路徑以順時針方向巡迴移動、在左側巡迴路徑以逆時針方向巡迴移動。The
更具體說明,將左右的出口側鏈輪62L、62R的旋轉速度以配合於入口側鏈輪61L、61R的旋轉速度的方式,同步控制出口側鏈輪62L、62R與入口側鏈輪61L、61R。換言之,當改變入口側鏈輪61L、61R旋轉速度時,亦會相應地使出口側鏈輪62L、62R的速度改變。薄膜的搬運速度,係主要藉由改變出口側鏈輪62L、62R的速度所控制。如此在拉伸裝置100中,由於為控制入口側鏈輪61L、61R並調整薄膜的搬運速度的結構,因此使向拉伸裝置100供應薄膜的上游設備(例如,薄膜製造裝置)變得更易於配合薄膜的搬運速度。More specifically, the
此外,使出口側鏈輪62L、62R與入口側鏈輪61L、61R同步控制,並非指出口側鏈輪62L、62R與入口側鏈輪61L、61R的速度實際一致。換言之,在本實施形態中的同步控制,係指以使出口側鏈輪62L、62R與入口側鏈輪61L、61R的速度一致的方式控制,根據鏈輪的形狀差異等的理由,實際亦包含在速度產生偏差的狀態。另外,亦可不使出口側鏈輪62L、62R與入口側鏈輪61L、61R以速度一致的方式同步控制。Note that synchronous control of the
在取入薄膜的入口部,藉由在左右巡迴路徑運行的夾具單元CU抓持薄膜的兩側緣。並且,藉由以基準軌11所引導的夾具把持部30的移動,所抓持的薄膜進入薄膜搬運區TA的預熱區Za。此外,左右的夾具單元CU,相互對應的夾具單元CU彼此在左右方向鄰接並抓持薄膜。換言之,左右的夾具單元CU,係不以在縱向錯開地抓持薄膜的方式控制運作。At the entrance portion for taking in the film, both side edges of the film are gripped by the gripper unit CU running on the left and right circuit paths. Then, the gripped film enters the preheating zone Za of the film conveying zone TA by the movement of the
在預熱區Za中,左右之循環路徑的間隔距離(亦即TD間距)配置為相當於薄膜的初期幅寬並遍布整個區域且左右的循環路徑相互平行。另外,間距設定軌12與基準軌11之間的間隔距離亦以綜觀整個區域而仍成為最大值(MD間距為最小值)的方式設定。據此,在預熱區Za中,皆未進行薄膜的橫拉伸與縱拉伸,僅進行使薄膜預熱至可拉伸的溫度的處理。In the preheating zone Za, the distance between the left and right circulation paths (ie, the TD pitch) is arranged so as to correspond to the initial width of the film and spread over the entire area, and the left and right circulation paths are parallel to each other. In addition, the interval distance between the
薄膜通過預熱區Za後,進入拉伸區Zb。在拉伸區Zb中,隨著從預熱區Za之側朝向熱處理區Zc,使左右之循環路徑的相隔距離逐漸擴大。換言之,在拉伸區Zb中,左右的循環路徑,係設為從入口側朝向出口側間隔擴大的末端展開狀。據此,在拉伸區Zb中,夾具把持部30彼此的橫向間隔(TD間隔)逐漸變大。另外,在拉伸區Zb中,間距設定軌12與基準軌11之間的間隔距離隨著從預熱區Za之側朝向熱處理區Zc而逐漸變短。因此,當夾具單元CU在拉伸區Zb運行時,夾具單元CU的間距設定輥57藉由間距設定軌12所引導並向基準軌11移動,其結果,滑件40移動至夾具把持部30的一端側(夾具側)。據此,夾具把持部30彼此之縱向的間隔(MD間隔)逐漸變大。因此,在拉伸區Zb中,薄膜在TD方向之拉伸(橫拉伸)的同時亦進行MD方向之拉伸(縱拉伸)。After the film passes through the preheating zone Za, it enters the stretching zone Zb. In the stretching zone Zb, the distance between the left and right circulation paths is gradually increased from the side of the preheating zone Za toward the heat treatment zone Zc. In other words, in the stretching zone Zb, the left and right circulation paths are formed in a terminal developed shape in which the interval is widened from the inlet side toward the outlet side. Accordingly, in the stretching zone Zb, the lateral interval (TD interval) between the
通過拉伸區Zb並受橫拉伸與縱拉伸之雙軸同時拉伸的薄膜,接著進入熱處理區Zc。在熱處理區Zc中,將左右之循環路徑的間隔距離設定為相當於拉伸後之薄膜的幅寬並遍布整個區域地使左右之循環路徑配置為相互平行,間距設定軌12與基準軌11之間的間隔距離亦綜觀整個區域而仍成為最小值(MD間距為最大值)。因此,在熱處理區Zc中,皆未進行薄膜的橫拉伸與縱拉伸,僅進行溫度調整等的熱處理。The film that passes through the stretching zone Zb and is subjected to biaxial simultaneous stretching of transverse stretching and longitudinal stretching, and then enters the heat treatment zone Zc. In the heat treatment zone Zc, the distance between the left and right circulation paths is set to be equivalent to the width of the film after stretching, and the left and right circulation paths are arranged parallel to each other over the entire area. The distance between the
在熱處理區Zc之終端的出口,使由左右的夾具20所為的薄膜之抓持解放,薄膜直行。夾具把持部30由基準軌11所引導並以環狀巡迴移動。At the exit at the end of the heat treatment zone Zc, the grip of the film by the left and right clamps 20 is released, and the film runs straight. The
如以上所述,使從入口側所供應的薄膜在縱橫之兩方向同時拉伸並從出口側送出。As described above, the film supplied from the inlet side is simultaneously stretched in both the longitudinal and lateral directions and sent out from the outlet side.
接著,針對TD間距及MD間距的調整方法進行說明。Next, an adjustment method of the TD pitch and the MD pitch will be described.
在拉伸裝置100中,藉由調整TD間距及MD間距,能夠改變橫向之拉伸量與縱向之拉伸量。In the stretching
對於調整TD間距,使在拉伸區Zb的各中間軌道部16藉由第1調整機構71而移動,從而改變左右之軌道單元15的間隔。另外,對於調整MD間距,藉由在拉伸區Zb的軌道單元15的第2調整機構75,改變基準軌11與間距設定軌12之間的間隔。藉此,改變由間距設定軌12所引導的間距設定輥57與由基準軌11所引導的引導輥56之間的間隔,滑件40(參照圖4)移動,並使MD間隔改變。To adjust the TD pitch, each
在此,在拉伸裝置100中,根據夾具單元CU的TD間距與MD間距,適當的夾具個數為不同。當實際的夾具個數與適當的夾具個數產生差額時,從夾具單元CU向軌道單元15作用負荷。Here, in the
具體而言,對於設定的TD間距及MD間距,在夾具個數適當(實際的夾具個數=適當的夾具個數)的情況下,夾具單元CU的間距設定輥57,對於軌道單元15的間距設定軌12為未接觸,即使有接觸亦是以較小的力接觸。Specifically, for the set TD pitch and MD pitch, when the number of jigs is appropriate (the actual number of jigs = the appropriate number of jigs), the
圖5係表示在夾具個數較適當個數更少的情況,圖6係表示在夾具個數較適當個數更多的情況。此外,在圖5及圖6中,將連結機構50等簡略化而圖示。FIG. 5 shows a case where the number of jigs is smaller than an appropriate number, and FIG. 6 shows a case where the number of jigs is larger than an appropriate number. In addition, in FIG.5 and FIG.6, the
如圖5所示,在夾具個數較適當個數更少的情況下,由於藉由少量的夾具單元CU,實現已設定好的TD方向及MD方向的間距,因此在夾具單元CU作用有往使MD方向的間距變大之方向的力。據此,在夾具個數過少的狀態中,如圖5中箭頭所示,間距設定輥57在左右方向以靠近薄膜的方式向薄膜側(拉伸裝置100的左右方向之中央側)推壓間距設定軌12。As shown in FIG. 5 , when the number of clamps is less than the appropriate number, a small number of clamp units CU are used to realize the set pitches in the TD direction and the MD direction. The force in the direction of increasing the pitch in the MD direction. Accordingly, in a state in which the number of clips is too small, the
相反地,在夾具個數較適當個數更多的情況下,在夾具單元CU作用有往使MD方向的間距變小之方向的力。據此,在夾具個數過大的狀態中,如圖6中箭頭所示,使間距設定輥57以從薄膜遠離的方式向左右方向之反薄膜側推壓間距設定軌12。Conversely, when the number of clips is larger than the appropriate number, a force in the direction of reducing the pitch in the MD direction acts on the clip unit CU. Accordingly, in a state where the number of clips is too large, the
如此一來由於間距設定輥57推壓間距設定軌12,從而有間距設定輥57或間距設定軌12產生變形、並使夾具單元CU之間距調整的精度下降之虞。特別當間距設定輥57在向間距設定軌12推壓的狀態下使間距設定軌12移動而調整MD間距時,對於具有第2調整馬達76及螺桿機構77的第2調整機構75亦會產生巨大的負荷,從而有降低機械壽命之虞。As a result, since the
在此,在拉伸裝置100中,為避免此種事態,在將夾具個數調整為適當之個數的同時,調整TD方向及MD方向的間距。此外,在拉伸裝置100中,分別在間距之調整與夾具個數之調整,以左右相互同步之方式,控制驅動機構60與調整機構70。Here, in the
具體而言,在拉伸裝置100中,藉由第2調整機構75的第2調整馬達76之力矩值T檢測從夾具單元CU向軌道裝置10L、10R作用的負荷,從而根據力矩值T調整夾具個數。夾具個數能夠藉由暫時增減出口側鏈輪62L、62R的旋轉速度而調整。換言之,藉由相對於以相同速度旋轉的入口側鏈輪61L、61R改變出口側鏈輪62L、62R的相位,從而調整夾具個數。Specifically, in the stretching
更詳細說明,在拉伸裝置100中,將力矩值T與所預定的第1閾值及第2閾值作比較,並判定夾具個數為過少或過多,以成為適當之夾具個數的方式控制出口側鏈輪62L、62R的運作。此外,在拉伸裝置100中,左右的各個第2調整機構75的任一的第2調整馬達76的力矩值T,無論是在大於第1閾值、或是在小於第2閾值的情況下,皆以同樣的方式控制左右之出口側鏈輪62L、62R之雙方的運作。In more detail, in the stretching
第2調整馬達76的力矩值T,係作為具有正負的值而取得。在本實施形態中,將第2調整馬達76逆旋轉(換言之,使間距設定軌12從基準軌11遠離)之方向的力矩作為正力矩值T。The torque value T of the
第1閾值為具有正值的閾值,第2閾值為具有負值的閾值。第1閾值係為用以判定夾具個數是否過少的閾值,第2閾值係為用以判定夾具個數是否過多的閾值。以下將第1閾值作為「+T1」、第2閾值作為「-T2」。The first threshold is a threshold having a positive value, and the second threshold is a threshold having a negative value. The first threshold is a threshold for judging whether the number of jigs is too small, and the second threshold is a threshold for judging whether the number of jigs is too large. Hereinafter, the first threshold value is referred to as "+T1", and the second threshold value is referred to as "-T2".
關於第1閾值+T1及第2閾值-T2的技術意義,以夾具個數過少的情況為例進行說明。The technical significance of the first threshold value +T1 and the second threshold value -T2 will be described by taking a case where the number of jigs is too small as an example.
第2調整馬達76,係以成為從控制器80所指示之旋轉位置的方式而控制運作。在夾具個數處於適當範圍內的情況下,第2調整馬達76產生用以成為所指示之旋轉位置的機械損失(mechanical loss)量的力矩(以下將機械損失量的力矩值T稱為「機械損失力矩T0」)。機械損失力矩T0為用以使第2調整馬達76旋轉並驅動間距設定軌12所產生的力矩,在第2調整馬達76逆旋轉時產生+T0、正旋轉時產生-T0的機械損失。換言之,在夾具個數處於適當範圍的情況下,第2調整馬達76產生的力矩值T,呈從+T0到-T0的範圍內(+T0≧T≧-T0)。The
在夾具個數過少的情況下,夾具單元CU向薄膜側(圖5中下方向)推壓軌道單元15。間距設定軌12,藉由從夾具單元CU的間距設定輥57接受的推壓力向接近基準軌11的方向推壓。此推壓力,係作為使第2調整馬達76正旋轉之方向的力矩並經由螺桿機構77作用於第2調整馬達76。When the number of clips is too small, the clip unit CU pushes the
據此,只要旋轉位置的指示未變化,第2調整馬達76藉由從夾具單元CU接受的推壓力使間距設定軌12以不向基準軌11移動的方式(以維持間距設定軌12的方式)控制運作。換言之,第2調整馬達76,除機械損失力矩T0以外,還產生逆旋轉方向的力矩,以抵抗由推壓力所產生之正旋轉方向的力矩。藉此,第2調整馬達76為了成為指定的旋轉位置,產生超出從機械損失力矩+T0至-T0之範圍的力矩值。在夾具個數過少的狀態中,由於第2調整馬達76產生逆旋轉方向的力矩,換言之,由於使第2調整馬達76產生正力矩,藉由比較作為正閾值的第1閾值+T1與力矩值T,能夠判定夾具個數過少。Accordingly, the
相反地,在夾具個數過多的情況下,由於從夾具單元CU向軌道單元15作用的推壓力方向呈相反,因此以抵抗推壓力的方式第2調整馬達76所產生之力矩的方向亦呈相反。據此,作為負閾值的第2閾值-T2成為判定夾具個數過多的閾值。Conversely, when there are too many clamps, since the direction of the pressing force acting from the clamp unit CU to the
如此一來,作為正閾值的第1閾值+T1,係為用以判定夾具個數是否過少的閾值,作為負閾值的第2閾值-T2,係為用以判定夾具個數是否過多的閾值。第1閾值+T1為較機械損失力矩+T0更大的值,第2閾值-T2為較機械損失力矩-T0更小的值。In this way, the first threshold value + T1, which is a positive threshold value, is a threshold value for determining whether the number of clamps is too small, and the second threshold value -T2, which is a negative threshold value, is a threshold value for determining whether the number of clamps is too large. The first threshold value +T1 is a value larger than the mechanical loss torque +T0, and the second threshold value -T2 is a value smaller than the mechanical loss torque -T0.
以下,參照圖7及圖8所示的流程圖,針對在拉伸裝置100中的夾具單元CU之TD方向及MD方向的間距調整方法進行具體說明。Hereinafter, with reference to the flowcharts shown in FIGS. 7 and 8 , the method for adjusting the pitch in the TD direction and the MD direction of the clamp unit CU in the
TD方向及MD方向的間距調整,係在未向拉伸裝置100供應薄膜的狀態下所執行。藉此,間距調整能夠降低薄膜的損失並節約能源。另外,亦可構成為設有檢測薄膜未供應至拉伸裝置100的檢測器,當藉由該檢測器檢測出薄膜未供應至拉伸裝置100時,執行TD方向及MD方向的間距調整。此外,TD方向及MD方向的間距調整,並不限定於在未向拉伸裝置100供應薄膜的狀態下執行。The pitch adjustment in the TD direction and the MD direction is performed in a state where the film is not supplied to the stretching
另外,TD方向及MD方向的間距調整,係在薄膜搬運區未升溫的狀態下所進行。藉此,在間距調整時能夠節約能源。另外,在此情況下,例如亦可構成為當基於溫度感測器或加熱器的開-關(on-off)信號檢測薄膜搬運區未升溫時,執行TD方向及MD方向的間距調整。此外,TD方向及MD方向的間距調整,並不限定於在薄膜搬運區未升溫的狀態下進行。In addition, the pitch adjustment in the TD direction and the MD direction was performed in a state where the temperature of the film conveying zone was not raised. Thereby, energy can be saved during pitch adjustment. In this case, for example, when it is detected that the temperature of the film transfer area is not raised based on an on-off signal of a temperature sensor or a heater, the pitch adjustment in the TD direction and the MD direction may be performed. In addition, the pitch adjustment in the TD direction and the MD direction is not limited to being performed in a state where the temperature of the film conveying zone is not raised.
控制器80,係藉由操作者輸入間距的設定條件,當按下自動調整按鈕(圖中省略)時,執行圖7所示的處理。The
在圖7所示的處理中,於步驟S10至步驟S18,執行TD間距及MD間距的調整(自動擴大縮小)。在自動擴大縮小中,於步驟S10至步驟S13首先調整TD方向的間距,之後於步驟S14至步驟S17調整MD方向的間距。在步驟S19至步驟S21中,執行夾具個數的最終調整(個數整合)。以下針對各步驟進行具體說明。In the processing shown in FIG. 7 , in steps S10 to S18 , adjustment of the TD pitch and the MD pitch (automatic enlargement/reduction) is performed. In the automatic enlargement and reduction, the spacing in the TD direction is first adjusted in steps S10 to S13 , and then the spacing in the MD direction is adjusted in steps S14 to S17 . In steps S19 to S21 , final adjustment of the number of jigs (number integration) is performed. The following describes each step in detail.
在步驟S10中,基於操作者已設定好的條件,設定TD方向的擴大縮小條件。具體而言,計算操作者已設定好之條件的TD間距,並計算執行該TD間距的拉伸區Zb之各第1調整馬達72的旋轉位置。並且,於步驟S11,以成為已計算好的旋轉位置的方式,向各第1調整馬達72的驅動器(圖中省略)傳送通電指令,從而驅動第1調整馬達72。In step S10 , based on the conditions set by the operator, the expansion and contraction conditions in the TD direction are set. Specifically, the TD pitch of the conditions set by the operator is calculated, and the rotational position of each
在步驟S12中,與於步驟S11之驅動第1調整馬達72並調整TD間距同時進行,執行夾具個數的調整處理。夾具個數調整處理,係為在驅動第1調整馬達72直到呈步驟S11所設定好之條件的旋轉位置為止的期間,監視第2調整馬達76的力矩並調整夾具個數的處理。夾具個數調整處理將於後述詳細說明。驅動第1調整馬達72直到步驟S10所計算好的旋轉位置為止,當步驟S13的夾具個數調整處理完成時,完成TD方向的調整(步驟S13)。In step S12, simultaneously with the driving of the
接著,在步驟S14中,基於操作者已設定好的條件,設定MD方向的擴大縮小條件。具體而言,計算要成為操作者已設定好之條件的MD間距,並計算達成該MD間距的拉伸區Zb之各第2調整馬達76的旋轉位置。並且,於步驟S15,以成為已計算好的旋轉位置的方式,向各第2調整馬達76的驅動器傳送通電指令從而驅動第2調整馬達76。在驅動第2調整馬達76直到已計算好的旋轉位置為止的期間,執行夾具個數調整處理(步驟S16)。驅動第2調整馬達76直到已計算好的旋轉位置為止,當步驟S16的個數調整處理完成時,完成MD方向的調整(步驟S17)。此外,步驟S16的夾具個數調整處理,與步驟S12的夾具個數調整處理相同。另外,第2調整馬達76在達到已計算好的旋轉位置後,以再次維持該旋轉位置的方式而控制。Next, in step S14, based on the conditions set by the operator, the conditions for expansion and contraction in the MD direction are set. Specifically, the MD pitch to be a condition set by the operator is calculated, and the rotational position of each
當如此調整TD間距及MD間距的兩方後,完成自動擴大縮小(步驟S18)。When both of the TD pitch and the MD pitch are adjusted in this way, automatic enlargement and reduction is completed (step S18 ).
在此,關於在步驟S12及S16中的夾具個數處理,參照圖8進行說明。如上所述,步驟S12及步驟S16,為調整TD間距、或是為調整MD間距,差別僅在於執行的時機不同。Here, the jig number processing in steps S12 and S16 will be described with reference to FIG. 8 . As described above, step S12 and step S16 are for adjusting the TD pitch or for adjusting the MD pitch, and the difference is only in the timing of execution.
如圖8所示,在夾具個數調整處理中,首先,於步驟S30,從各第2調整馬達76的力矩感測器78取得作為負荷數據的力矩值T。As shown in FIG. 8 , in the jig number adjustment process, first, in step S30 , a torque value T as load data is acquired from the
在步驟S31及步驟S33中,將於步驟S30取得的力矩值T與所預定的閾值(第1閾值+T1、第2閾值-T2)進行比較。In step S31 and step S33, the torque value T acquired in step S30 is compared with predetermined threshold values (1st threshold value + T1, 2nd threshold value - T2).
在步驟S31中,判定所獲得的第2調整馬達76的力矩值T,是否為第1閾值+T1以下。在力矩值T大於第1閾值+T1的情況下,由於為如上所述之夾具個數過少的狀態,因此於步驟S32,以暫時將出口側鏈輪62L、62R減速的方式控制第1驅動馬達64L及第2驅動馬達64R的運作。藉此,夾具個數增加,隨著夾具個數的增加而減少向間距設定軌12作用的負荷(換言之,第2調整馬達76的力矩值T的絕對值)。在力矩值T為第1閾值+T1以下的情況下,往步驟S33前進。In step S31, it is determined whether or not the obtained torque value T of the
在步驟S33中,判定第2調整馬達76的力矩值T,是否為第2閾值-T2以上。在力矩值T小於第2閾值-T2的情況下,由於為夾具個數過多的狀態,因此於步驟S34以暫時將出口側鏈輪62L、62R加速的方式控制第1驅動馬達64L及第2驅動馬達64R的運作。藉此,夾具個數減少,隨著夾具個數的減少而減少向間距設定軌12作用的負荷(換言之,第2調整馬達76的力矩值T的絕對值)。在力矩值T為第2閾值-T2以上的情況下,往步驟S35前進。In step S33, it is determined whether or not the torque value T of the
在步驟S35中,判定第1調整馬達72或第2調整馬達76是否已驅動至指示的旋轉位置為止,換言之,判定TD間距、MD間距是否已達成為操作者已設定好的條件。若未達成所設定的間距,則從步驟S35返回至步驟S30,並再次執行從步驟S30的處理。若有達成所設定的間距,則完成夾具個數調整處理,返回圖7所示的步驟S13或步驟S16。如此,圖8的步驟S30至步驟S35所示的處理,係在以達成已設定好的TD間距或MD間距的方式驅動第1調整馬達72或第2調整馬達76的期間,並列執行。In step S35, it is determined whether the
如上所述,在以使第2調整馬達76的力矩值不超出閾值的方式調整夾具個數的同時,在TD間距及MD間距調整為所期望的間距後,如於圖7所示的步驟S19至步驟S21,進行夾具個數的個數整合。As described above, while adjusting the number of clamps so that the torque value of the
在步驟S19中,進行夾具個數的計測。在步驟S20中,藉由操作者判定是否按下個數整合按鈕。In step S19, the number of jigs is measured. In step S20, it is determined by the operator whether or not the number integration button is pressed.
當按下個數整合按鈕時,往步驟S21前進,進行夾具個數的自動調整。具體而言,判斷在步驟S19所計測的夾具個數,與在步驟S10從已設定好的條件所計算的目標個數是否一致,在不一致的情況下,以使所計測的夾具個數成為目標個數的方式,根據夾具個數與目標個數之差額而暫時增減第1驅動馬達64L及第2驅動馬達64R的旋轉速度。藉此,以使夾具個數成為目標個數的方式進行調整。當夾具個數調整後結束處理。When the number integration button is pressed, the process proceeds to step S21, and automatic adjustment of the number of jigs is performed. Specifically, it is determined whether the number of jigs measured in step S19 matches the target number calculated from the set conditions in step S10, and if they do not match, the measured number of jigs is set as the target The number of objects temporarily increases or decreases the rotational speeds of the
針對步驟S21所示的夾具個數的個數整合,進行詳細說明。The number integration of the number of jigs shown in step S21 will be described in detail.
夾具個數與第1驅動馬達64L及第2驅動馬達64R之旋轉的關係,能夠從各結構的規格等預先掌握。換言之,預先掌握相對於入口側鏈輪61L、61R應何種程度地提早點火或是延遲點火出口側鏈輪62L、62R、何種程度地增減夾具個數之關係。據此,例如在實際夾具個數較設定個數更多的情況下,以對應於個數之差額的角度量並以所預定的時間提早點火出口側鏈輪62L、62R。換言之,暫時增加出口側鏈輪62L、62R的旋轉速度。藉此,由於夾具單元CU會暫時快速通過出口側鏈輪62L、62R並從拉伸區域排出,因而減少夾具個數。此外,進行夾具個數的調整後,入口側鏈輪61L、61R與出口側鏈輪62L、62R將再次同步並以相同速度旋轉。The relationship between the number of clamps and the rotation of the
相反地,在實際夾具個數較設定個數更少的情況下,以對應於個數之差額的角度量延遲點火出口側鏈輪62L、62R(暫時減少速度)。藉此,由於夾具單元CU會暫時延遲通過出口側鏈輪62L、62R並從拉伸區域排出,因而增加夾具個數。如此一來,調整夾具個數,從而結束處理。Conversely, when the actual number of clamps is smaller than the set number, the ignition
此外,步驟S21所示的個數整合,較佳為以薄膜搬運區內的溫度為在實際拉伸時的溫度之安定的狀態下進行。藉此,能夠排除夾具單元CU等的熱膨脹之影響,從而進行夾具個數的調整。In addition, it is preferable to perform the number integration shown in step S21 in a state where the temperature in the film conveying zone is stable as the temperature at the time of actual stretching.

另外,在夾具個數調整方法中,負荷數據係為調整馬達的力矩值,在控制出口側鏈輪之旋轉速度的步驟中,在調整馬達的力矩值超出為正值之第1閾值+T1的情況下,執行出口側鏈輪62L、62R的旋轉速度之增加或減少之任一方,在調整馬達的力矩值小於為負值之第2閾值-T2的情況下,執行出口側鏈輪62L、62R的旋轉速度之增加或減少之任一另一方。In addition, in the method for adjusting the number of clamps, the load data is the torque value of the adjustment motor, and in the step of controlling the rotation speed of the sprocket on the outlet side, the torque value of the adjustment motor exceeds the positive value of the first threshold value + T1.

以上為依本實施形態所作的說明,然而上述實施形態僅表示本發明適用例的一部分,本發明的技術範圍並不限定於上述實施形態的具體結構。The above description is based on the present embodiment, however, the above-described embodiment only shows a part of the application examples of the present invention, and the technical scope of the present invention is not limited to the specific structure of the above-described embodiment.
在上述實施形態中,左右的出口側鏈輪62L、62R係相互同步地被旋轉驅動。相對地,左右的出口側鏈輪62L、62R亦可為相互獨立地被旋轉驅動。在此情況下,亦可為根據右側的第2調整馬達76的力矩值T調整右側的夾具個數,並根據左側的第2調整馬達76的力矩值T調整左側的夾具個數。換言之,亦可為左右獨立執行夾具個數的調整。In the above-described embodiment, the left and right
另外,在上述實施形態中,左右的夾具單元CU,相互對應的夾具單元CU彼此以在左右方向並排的方式,沿巡迴路徑運行。另外,在以相同之縱向位置比較的情況下,右側的夾具單元CU與左側的夾具單元CU的MD間距,係為相互相同。相對地,MD間距亦可為左右不同。換言之,相互對應的左右之夾具單元CU彼此亦可為在左右方向未並排,而在縱向錯開。藉由使左右的MD間距不同,能夠使薄膜在斜向(在圖1所示的平面,傾斜於縱向及橫向之任一的方向)拉伸。In addition, in the above-described embodiment, the left and right gripper units CU and the mutually corresponding gripper units CU travel along the traveling route so as to be side by side with each other in the left-right direction. In addition, in the case of comparing at the same vertical position, the MD pitches of the clip unit CU on the right side and the clip unit CU on the left side are the same as each other. Conversely, the MD pitch may be different from left to right. In other words, the left and right clamp units CU corresponding to each other may not be arranged side by side in the left and right direction, but may be staggered in the longitudinal direction. By making the MD pitches on the right and left different, the film can be stretched in an oblique direction (in the plane shown in FIG. 1, oblique to either the longitudinal direction or the transverse direction).
另外,在上述實施形態中,於熱處理區Zc,在縱向與橫向皆無拉伸。相對地,於熱處理區Zc,亦可構成為使MD間距減少,從而使薄膜在MD方向收縮。藉此,能夠避免相較夾具20所抓持的薄膜之左右緣部,薄膜的左右方向之中央部分的拉伸量變小而變細(換言之,薄膜的左右之緣部較中央部分向搬運方向突出),亦即能夠避免產生翹曲現象。In addition, in the above-mentioned embodiment, in the heat treatment zone Zc, there is no stretching in both the longitudinal direction and the transverse direction. On the other hand, in the heat treatment zone Zc, the MD pitch may be reduced to shrink the film in the MD direction. Thereby, it can be avoided that the stretch amount of the central portion of the film in the left-right direction becomes smaller and thinner than the left and right edges of the film held by the clamp 20 (in other words, the left and right edges of the film protrude in the conveying direction from the central portion). ), that is, to avoid warping.
另外,在上述實施形態中,係在調整TD方向與MD方向之兩方向的間距的情況所作的說明,然而拉伸裝置100亦可僅調整TD方向及MD方向之任一的間距。在此情況下,可省略根據未調整之方向所進行的處理(圖7所示的步驟S10至步驟S13,或者步驟S14至步驟S17)。In addition, in the said embodiment, although it demonstrated the case of adjusting the pitch of both the TD direction and the MD direction, the stretching
另外,在上述實施形態中,檢測部為第2調整馬達76的力矩感測器78,第2調整馬達76的力矩值作為負荷數據所使用。相對地,負荷數據並不限定於第2調整馬達76的力矩值,檢測部亦不限定於力矩感測器78。例如,亦可為未設有力矩感測器78,而是將基於輸入至第2調整馬達76的電壓值、電流值、以及頻率等所計算的負荷力矩作為第2調整馬達76的力矩值。另外,亦可不使用力矩值,而是使用流往第2調整馬達76的電流值作為負荷數據。另外,亦可為設有負載感測器的結構,前述負載感測器係取代力矩感測器78而作為檢測部,並以負載感測器檢測從間距設定輥57向間距設定軌12所作用的負荷而作為負荷數據。另外,亦可為設有作為檢測部之位移感測器的結構,位移感測器檢測間距設定軌12的撓曲(變形)以作為負荷數據,前述撓曲(變形)係由從間距設定輥57向間距設定軌12所作用的負荷所導致。In addition, in the said embodiment, the detection part is the
另外,在上述實施形態中,係將第2調整馬達76逆旋轉(使間距設定軌12從基準軌11遠離)的力矩作為正力矩值所作的說明。相對地,力矩值的正負之設定並不限定於上述構成,亦可為任意設定。據此,關於第1閾值及第2閾值,亦能夠任意設定正負。另外,第1閾值及第2閾值的大小(絕對值),只要在夾具個數適當的正常時間而未執行夾具個數調整的情況下,亦能夠任意設定。換言之,在拉伸裝置100中,期望為設定用以判定夾具個數是否過少的閾值、與用以判斷是否過多的閾值,以根據夾具個數之多少而使夾具個數變得適當的方式控制出口側鏈輪62L、62R的運作。只要構成為如此,力矩值的設定或閾值的具體內容,並不限定於上述實施形態。In addition, in the above-described embodiment, the description was given by using the torque obtained by the reverse rotation of the second adjustment motor 76 (to move the
例如,與上述實施形態相反,在將第2調整馬達76正旋轉(間距設定軌12靠近於基準軌11)之方向的力矩值作為正力矩值的情況下,為正值的第1閾值+T1表示判定夾具個數是否過多的閾值,為負值的第2閾值-T2表示判定夾具個數是否過少的閾值。在此情況下,以下述的方式控制為佳,係為當第2調整馬達76的力矩值超出第1閾值+T1時,使出口側鏈輪62L、62R的旋轉速度增加,而當第2調整馬達76的力矩值小於第2閾值-T2時,使出口側鏈輪62L、62R的旋轉速度減少。在此情況下,亦達到與上述實施形態相同的作用效果。換言之,根據力矩值之正負的設定方法,將第1閾值+T1與第2閾值-T2具有的含義進行交換。據此,分別交換在第2調整馬達76的力矩值超出第1閾值+T1的情況下使出口側鏈輪62L、62R的旋轉速度增加或減少、或是在第2調整馬達76的力矩值小於第2閾值-T2的情況下使出口側鏈輪62L、62R的旋轉速度減少或增加。據此,控制器80期望構成為,在第2調整馬達76的力矩值T超出為正值之第1閾值+T1的情況下,執行出口側鏈輪62L、62R的旋轉速度之增加或減少之任一方,在第2調整馬達76的力矩值小於為負值之第2閾值-T2的情況下,執行出口側鏈輪62L、62R的旋轉速度之增加或減少之任一另一方。For example, contrary to the above-described embodiment, when the torque value in the direction in which the
另外,上述實施形態中,第2調整馬達76在正向旋轉的情況下與在逆向旋轉的情況下,第1閾值+T1及第2閾值-T2為共通。相對地,第2調整馬達76在正向旋轉的情況下與在逆向旋轉的情況下,亦可分別設定不同的第1閾值+T1及第2閾值-T2。例如,期望為在使第2調整馬達76旋轉並使間距設定軌12移動的機械損失大的情況下,分別個別設定第2調整馬達76在正向旋轉時的情況下的第1閾值+T1及第2閾值-T2、與逆向旋轉的情況下的第1閾值+T1及第2閾值-T2。In addition, in the above-described embodiment, the first threshold value +T1 and the second threshold value -T2 are common when the
在機械損失的大小(絕對值)較小的情況下,在第2調整馬達76正向旋轉的情況下與在逆向旋轉的情況下,閾值(第1閾值+T1、第2閾值-T2)與機械損失力矩(+T0、-T0)之間的差額不會產生巨大的差。換言之,以第1閾值+T1為例進行說明,第1閾值+T1與第2調整馬達76在正旋轉之情況下的機械損失力矩-T0之間的差(+T1+T0)、和第1閾值+T1與第2調整馬達76在逆旋轉之情況下的機械損失力矩+T0之間的差(+T1-T0),不會大幅變化。因此,如上述實施形態,即使不根據第2調整馬達76的旋轉方向,而是共通使用第1閾值+T1與第2閾值-T2,亦不會對夾具個數之調整產生大幅影響。When the magnitude (absolute value) of the mechanical loss is small, when the
另一方面,當機械損失大時,第2調整馬達76在正旋轉的情況下與在逆旋轉的情況下,閾值與機械損失力矩之間的差額會產生較大的差。因此,當不根據第2調整馬達76的旋轉方向而使第1閾值+T1及第2閾值-T2共通時,在第2調整馬達76逆旋轉的情況下,由於第1閾值+T1與機械損失力矩+T0之間的差額比較小,因此即使夾具個數稍微變得過多還是可以執行夾具個數調整處理。另一方面,在第2調整馬達76正旋轉的情況下,第1閾值+T1與機械損失力矩-T0之間的差額相對變大。因此,在第2調整馬達76正旋轉的情況下,即使夾具個數過多到與在逆旋轉的情況下的個數相同,仍無法執行夾具個數調整處理,若夾具個數沒有更多而成為過多,則無法執行夾具個數調整處理。如此,若使第2調整馬達76在正向旋轉的情況下與在逆向旋轉的情況下的第1閾值+T1及第2閾值-T2共通,則無論是僅以相同的個數而過多或過少,根據第2調整馬達76的旋轉方向可能進行夾具個數調整、也可能不進行夾具個數調整。換言之,根據第2調整馬達76的旋轉方向,調整夾具個數的時機會不同。On the other hand, when the mechanical loss is large, a large difference occurs between the threshold value and the mechanical loss torque when the
相對地,藉由相對於第2調整馬達76的旋轉方向分別設定第1閾值+T1及第2閾值-T2(換言之,設定正旋轉用的第1閾值+T1及第2閾值-T2、與逆旋轉用的第1閾值+T1及第2閾值-T2之共4個閾值),若夾具個數過多或過少的個數相同,則能夠以不依據第2調整馬達76的旋轉方向,而在相同時機進行夾具個數調整的方式構成。例如,較佳為將第1閾值+T1與第2閾值-T2,作為分別相對於機械損失力矩+T0、-T0增減指定的力矩值Td(T1=±T0+Td、T2=±T0-Td)的值而設定。藉此,由於能夠使執行夾具個數之控制的時機相同,因此能夠穩定進行夾具個數之調整。On the other hand, by setting the first threshold value +T1 and the second threshold value -T2 with respect to the rotation direction of the second adjustment motor 76 (in other words, setting the first threshold value +T1 and the second threshold value -T2 for forward rotation, and the reverse The first threshold value for rotation + T1 and the second threshold value - T2 (a total of 4 threshold values), if the number of clamps is too large or too few are the same, the rotation direction of the
另外,在根據第2調整馬達76的旋轉方向分別個別設定第1閾值及第2閾值的情況下,第1閾值與第2閾值,亦可設定為相同之正負。具體說明,例如,亦可為將第1閾值作為正值之閾值而設定、將第2閾值作為較第1閾值小的正值之閾值而設定。如此,第2閾值無關於與第1閾值之間的正負之異同,而是作為較第1閾值更小的值而設定。在此情況下,當第2調整馬達76的力矩值T位於第1閾值與第2閾值之間的範圍內時,與上述實施形態相同,不進行夾具個數的調整。當第2調整馬達76的力矩值T大於第1閾值時,作為夾具個數過少的狀態,使出口側鏈輪62L、62R暫時減速而使夾具個數增加。當第2調整馬達76的力矩值T小於第2閾值時,作為夾具個數過多的狀態,使出口側鏈輪62L、62R暫時加速而使夾具個數減少。如此,即使將第1閾值與第2閾值設定為正負相同的閾值,仍然能夠達成與上述實施形態相同的作用效果。另外,第1閾值及第2閾值的任一方,亦可設定為0。In addition, when the first threshold value and the second threshold value are individually set according to the rotation direction of the
另外,在上述實施例中,入口側鏈輪61L、61R,藉由共通的第3驅動馬達65所驅動。相對地,左右之入口側鏈輪61L、61R,亦可藉由相互不同的電動馬達所獨立驅動。換言之,第2驅動單元65,亦可具有驅動左側的入口側鏈輪61L的電動馬達、與驅動右側的入口側鏈輪61R的電動馬達。In addition, in the above-described embodiment, the inlet-
另外,在上述實施形態中,藉由旋轉驅動入口側鏈輪61L、61R及出口側鏈輪62L、62R且夾具單元CU在運行於循環路徑的狀態下控制出口側鏈輪62L、62R的運作,從而調整夾具個數。相對地,亦可為在停止第1驅動單元64及第2驅動單元65的運作、並停止循環路徑上的夾具單元CU之運行的狀態下調整夾具個數。換言之,圖7所示步驟S10至步驟S18及圖8所示的步驟S30至步驟S35的處理,亦可在停止第1驅動單元64及第2驅動單元65之運作的狀態下執行。In addition, in the above-described embodiment, by rotationally driving the
另外,在上述實施形態中,藉由控制第1驅動單元64的運作並暫時增加或減少出口側鏈輪62L、62R的旋轉速度,從而調整夾具個數。相對地,亦可控制第2驅動單元65的運作並暫時增加或減少入口側鏈輪61L、61R的旋轉速度,從而調整夾具個數。另外,亦可控制入口側鏈輪61L、61R與出口側鏈輪62L、62R之兩方的旋轉速度,從而調整夾具個數。換言之,藉由控制入口側鏈輪61L、61R及出口側鏈輪62L、62R的至少一方的運作從而可調整夾具個數。在任一種情況下,入口側鏈輪61L、61R與出口側鏈輪62L、62R,當以暫時增大相互之旋轉速率差的方式控制其運作則夾具個數減少,當以暫時減少相互之旋轉速率差的方式控制其運作則夾具個數增加。In addition, in the above-described embodiment, the number of clamps is adjusted by controlling the operation of the
