Abstract

提供一种能够通过高效且安全性高的方法而对双轴延伸聚酯薄膜赋予热封性的激光加工装置。激光加工装置具有激光振荡器，将从激光振荡器输出的激光向由双轴延伸聚酯层单体或者在表面含有双轴延伸聚酯层的层叠体构成的薄膜照射，对薄膜的被照射激光的区域赋予热封性。激光加工装置可以具有将激光的光斑形状整形为规定的形状的光学元件、或者载置薄膜的薄膜载置部。

Description

针对薄膜的激光加工方法
技术领域
本发明涉及一种激光加工装置。
背景技术
双轴延伸聚对苯二甲酸乙二醇酯薄膜等双轴延伸聚酯薄膜由于强度、耐热性、尺寸稳定性、耐药性、保香性等优异，因此作为各种包装用材料而有用。因此，期待对这种薄膜彼此进行热封而形成的软包装袋等包装袋。
然而，具有取向性的薄膜缺乏热封性。因此，例如，专利文献1中公开有如下方法，即，以短脉冲对双轴延伸聚酯薄膜的表面照射电磁波，对表面进行改性而赋予热封性。
专利文献1：日本特公平4-26339号公报
发明内容
专利文献1所公开的短脉冲照射方法，为了不使双轴延伸聚酯薄膜的内部取向性受损，需要利用氙气灯等而产生高输出的短脉冲。氙气灯的能效较低，另外，在广阔的范围射出电磁波，因此难以确保安全性。因此，对双轴延伸聚酯薄膜赋予热封性的方法并未付出面向实用化的努力。
本发明就是鉴于这种问题而提出的，其目的在于提供一种能够通过高效且安全性高的方法对双轴延伸聚酯薄膜赋予热封性的加工装置。
用于解决上述问题的本发明的一个方案是针对薄膜的激光加工方法，其用于使用激光加工装置对由双轴延伸聚酯层单体或者在表面含有双轴延伸聚酯层的层叠体构成的薄膜赋予热封性，该激光加工装置具有红外线激光振荡器、包含辊的薄膜载置部、以及对从红外线激光振荡器输出的红外线激光进行引导的激光引导部，该激光加工方法包括如下工序：将薄膜载置于薄膜载置部；利用激光引导部对从激光振荡器输出的红外线激光进行引导而使红外线激光向薄膜照射；使激光引导部移动，以使得红外线激光向薄膜的照射位置发生变化；以及通过辊进行薄膜的卷取以及送出，以使得红外线激光向薄膜的照射位置发生变化，通过向薄膜的规定区域照射红外线激光而对该区域赋予热封性。

具体实施方式
(第1实施方式)
(激光加工装置)
图1中示出了一个实施方式所涉及的激光加工装置10的概念图。激光加工装置10包含：激光振荡器20；以及光学元件30，其将从激光振荡器20输出的激光60的光斑形状整形为规定的形状，对作为被加工物的双轴延伸聚酯层单体薄膜或在表面含有双轴延伸聚酯层的层叠体薄膜70(下面，称为薄膜70)照射激光。可以具备对薄膜70进行载置的薄膜载置部40。能够对薄膜70的规定位置照射从光学元件30透过的激光60而对其赋予热封性。通过利用比氙气灯更容易控制光的照射的激光振荡器能够确保安全性。
(激光振荡器)
对于激光振荡器20，可以使用公知的激光振荡器。特别优选包含能量容易高效地被薄膜70吸收的红外线波长的二氧化碳激光。激光振荡器20能够利用控制部50对激光60的输出、脉冲宽度等进行调整并输出。激光振荡器20的数量并不限定于1台，也可以使用多台。
(光学元件)
光学元件30具有如下功能，即，将从激光振荡器20输出的激光60的光斑形状整形为规定的形状而向薄膜70上照射。光学元件30可以使用例如衍射光学元件、多面镜、柱面透镜等光学元件，可以根据需要对多个光学元件进行组合而构成。
图2A是表示光学元件30的具体例的剖面图。图2A中示出了将衍射光学元件31用作光学元件30的情况下的激光加工装置11的剖面图。衍射光学元件31是在由与所使用的激光60的波长相应的ZnSe、石英等材质构成的基板上，基于规定的光斑形状并通过计算机模拟等而设计的，具有通过蚀刻、微型机械加工、复制或者光刻等而形成的微细的凹凸图案。入射至衍射光学元件31的激光60从衍射光学元件31透过而形成为规定的光斑形状。
图3A、图3B中示出了从激光振荡器20输出的光斑形状S0以及由光学元件30整形后的光斑形状S1的例子。光学元件30将从激光振荡器20输出的激光60的点状的光斑形状(图3A的左侧)整形为例如规定长度的线段形状的光斑形状(图3A的右侧)。能够由衍射光学元件31形成的光斑形状S1并不限定于线段形状，通过改变凹凸图案，从而例如图3B所示，可以采用虚线状、点划线状、规定宽度的带状、四边形的四边状、波状、“コ”字状、“X”字状、椭圆的圆周状等任意形状。
图4中示出了使得利用衍射光学元件31整形的激光60的光斑形状形成为薄膜70的热封性赋予预定区域的形状的激光加工装置11。如图4所示，如果在形成对矩形形状的双轴延伸聚酯的薄膜70的周缘的区域赋予热封性的密封部90的情况下，则能够使光斑形状形成为作为密封部90的形状的框缘形。这样，通过使光斑形状形成为热封性赋予预定区域的形状，从而不需要利用激光60进行扫描的工序，能够大幅减少为了赋予热封性所需的加工时间。另外，不需要对光学元件30进行驱动的机构，因此能够使激光加工装置10的构造变得简单。
图2B中示出了作为光学元件30的其他例子而使用柱面透镜32的情况下的激光加工装置12的剖面图。柱面透镜32是由平面和圆筒面构成的透镜，设置为使得平面朝向激光振荡器20、且使得圆筒面朝向薄膜70。入射至柱面透镜32的平面侧的激光60在圆筒面侧的具有曲率的方向上扩散，因此如图3A所示，薄膜70上的光斑形状整形为规定长度的线段形状。
图2C中示出了作为光学元件30的又一其他例子而使用多面镜33的情况下的激光加工装置13的剖面图。多面镜33例如由8边形等多棱面体的反射镜和使该反射镜旋转的未图示的电机构成。通过对旋转的反射镜照射激光60，从而能够将由反射镜反射的激光60在薄膜70上进行扫描，连续地对图3A所示的规定长度的线段形状的光斑形状进行整形。还可以代替多面镜33而使用反射镜和电机组合后的流电扫描仪。
(热封性赋予方法)
图5中示出了利用激光加工装置10进行激光照射而赋予了热封性的双轴延伸聚酯的薄膜71的一个例子所涉及的平面图及其沿着A-A’线的剖面图。对薄膜71的周缘的区域照射激光60而降低表面的结晶度，由此赋予热封性，构成密封部90。在图示的例子中，在被赋予了热封性的区域形成有沿着激光60的扫描方向的加工痕迹80。
在图5所示的例子中，例如利用光学元件30使激光60形成为与TD方向平行的线段形状的光斑形状，通过将使光斑形状沿MD方向移动、和每次沿MD方向移动了规定距离时便以规定距离沿TD方向移动进行组合而利用激光60进行扫描。图6中示出了其他例子。在图6所示的例子中，使激光60的光斑形状形成为相对于TD方向以及与该TD方向正交的MD方向均不平行的、规定长度的线段形状的光斑S，使光斑S在薄膜72的周缘的区域移动1圈，由此能够对与图5所示的例子相同的范围的密封部90中的大部分区域照射激光60。
另外，作为赋予热封性的其他方法，可以利用衍射光学元件31对薄膜70照射激光60而使密封部90的形状形成为光斑形状。通过将光斑形状设为热封性赋予预定区域的形状，从而不需要利用激光60对薄膜70进行扫描的工序，能够大幅削减为了赋予热封性所需的加工时间。另外，不需要对光学元件30进行驱动的机构，因此能够使激光加工装置10的构造变得简单。
这样，通过适当地对激光60的光斑形状、尺寸以及移动进行设定、控制，能够适当地利用激光60在薄膜70的要赋予热封性的区域内进行扫描。特别地，如图6所示的例子那样，如果将激光60的光斑形状设为线段那样的具有延伸方向的形状，则在将不与延伸方向平行的方向设为光斑的移动方向的情况下，能够进行面扫描，因此能够实现高效的扫描。另外，能够使得光学元件30在与薄膜70平行的面内旋转，由此能够容易地对光斑形状的延伸方向进行变更，能够容易地对扫描区域的宽度进行调整。另外，可以将激光60的光斑形状设为带状、矩形形状等面形状而在薄膜70上进行扫描。
能够通过激光的照射使薄膜70的结晶度降低而形成加工痕迹80。另外，根据激光的输出、照射光斑的能量密度、照射速度等，加工痕迹80的方式各种各种，例如，有时形成为失去了平坦性而具有凹部或凸部的微细构造，还有时实施白化而使得光的反射率变化。另外，还有可能产生未形成加工痕迹的情况。
这样，通过激光60的照射而赋予热封性的方法，与以短脉冲照射高输出的电磁波而赋予热封性的方法相比，能够提高能效，另外，光(电磁波)不会在广阔的范围射出，因此即使实施了高输出化，也能够确保安全性。另外，根据本实施方式的激光加工装置，不使重量大的激光振荡器移动，因此能够降低驱动成本。
此外，薄膜70也可以不是双轴延伸聚酯的单层薄膜。对于在表面含有双轴延伸聚酯的各种层叠薄膜，也能够利用本实施方式的激光加工装置对双轴延伸聚酯层的表面赋予热封性。
(包装袋)
图7中示出了包装袋100的平面图以及侧视图。包装袋100是如下包装袋的一个例子所涉及的四个方向密封的袋，即，对于通过上述方法形成有密封部90的2个薄膜73，以形成有密封部90的面相对的方式使它们重叠而进行热封处理，由此形成收纳部110而制造包装袋。
利用薄膜73制造的包装袋的形状并不限定于四个方向密封的袋，也可以采用任意形状。例如，可以采用将1张薄膜折成2部分并对相应的周缘部进行热封而形成的三个方向密封的袋、将折成2部分的薄膜夹入2张薄膜之间并对周缘部进行密封而形成的具有自立性的柔软包装袋等。
(第2实施方式)
(激光加工装置)
图8中示出了一个实施方式所涉及的激光加工装置100的概念图。激光加工装置110具备：激光振荡器120；激光照射部130，其对作为被加工物的双轴延伸聚酯层单体薄膜或在表面含有双轴延伸聚酯层的层叠体薄膜70(下面，称为薄膜70)照射从激光振荡器120输出的激光160；薄膜载置部140，其载置薄膜70；以及控制部150，其对激光振荡器120、激光照射部130以及薄膜载置部140分别进行控制，激光加工装置110能够利用激光照射部130对薄膜70的规定位置照射激光160而赋予热封性。
(激光振荡器)
与第1实施方式所涉及的激光振荡器相同，因此将说明省略。
(激光照射部)
激光照射部130具有将从激光振荡器120输出的激光160调整为规定的光斑形状或扫描轨迹并照射至薄膜70上的功能。激光照射部130包含：激光引导部131，其将从激光振荡器120输出的激光160向薄膜70上引导，将圆形的光斑形状改变为规定的光斑形状；以及第1驱动部135、第2驱动部136，它们使激光引导部131例如在与薄膜70的表面平行的平面内移动而对薄膜70上的规定位置进行激光160的照射。
激光引导部131是对激光进行引导的光学系统，例如具有第1反射镜132、第2反射镜133以及第3反射镜134和衍射光学元件137。如图8所示，第1反射镜132配置为在X方向上以规定距离与激光振荡器120分离，能够利用第1驱动部135对该距离进行变更。第2反射镜133配置为在Z方向上以规定距离与第1反射镜132分离。第1反射镜132和第2反射镜133连结为一体，因此距离恒定。第3反射镜134配置为在Y方向上以规定距离与第2反射镜133分离，能够利用第2驱动部136对该距离进行变更。衍射光学元件137配置为在Z方向上以规定距离与第3反射镜134分离。第3反射镜134和衍射光学元件137连结为一体，因此距离恒定。
如图8所示，以规定的角度对各反射镜进行配置，从而，从激光振荡器120朝向X方向输出的激光160反射首先由第1反射镜132而向Z方向引导，接着由第2反射镜133反射而向Y方向引导，接着由第3反射镜134再次将其向Z方向引导，向衍射光学元件137上照射。最后，使向衍射光学元件137上照射的激光160变化为任意的光斑形状而向薄膜70上照射。
第1驱动部135和第2驱动部136例如分别由配置于XY方向上的气缸构成，基于来自控制部150的信号而使连结的激光引导部131在XY平面上移动。如图8所示，激光引导部131与第1驱动部135连结，因此能够向X方向进行驱动。第3反射镜134以及衍射光学元件137与第2驱动部136连结，因此相对于第1反射镜132以及第2反射镜133独立且一体地在Y方向上被驱动。如果确定了激光160的照射位置，则控制部150能够分别对第1驱动部135以及第2驱动部136进行控制而使激光照射部130向薄膜70上的照射位置移动。
对于激光引导部131使用3个反射镜，如果能够利用从激光振荡器120输出的激光160在薄膜70上进行扫描，则反射镜并不局限于3个，只要使用适当个数的反射镜即可，或者可以不使用反射镜。例如，还可以使用对反射镜和电机进行组合而成的流电扫描仪、利用电机使多棱面体的反射镜旋转并利用照射至反射镜的激光进行扫描的多面镜。另外，利用衍射光学元件衍射的激光160的光斑形状并不受到限定，可以采用规定长度的直线状、虚线状、点划线状、规定宽度的带状、四边形的四边状、波状、“コ”字状、“X”字状、椭圆的圆周状等任意形状。另外，为了改变激光160的光斑形状，可以使用柱面透镜等透镜等其他光学元件代替衍射光学元件137。另外，除了气缸以外，第1驱动部135和第2驱动部136还可以采用对伺服电机和导轨进行组合等公知的方式。
(薄膜载置部)
薄膜载置部140具有在进行激光照射时将薄膜70固定于激光照射部130的下部而进行输送的功能。薄膜载置部140例如由将薄膜70向激光照射部130的下部送出的绕出辊141以及按顺序对激光照射结束后的薄膜70进行卷取的卷取辊142构成。绕出辊141以及卷取辊142由控制部150驱动。
如果薄膜载置部140具有在进行激光照射时对薄膜70进行固定、输送的功能，则并不限定于辊状。例如，可以是能够对裁断后的单片薄膜进行固定、输送的桌台形状的载置台。这种薄膜载置部140在照射激光的过程中、或者与照射交替地由未图示的驱动部驱动而使薄膜70移动。基于薄膜载置部140的薄膜70的移动可以用于激光照射位置的定位，也可以用于单张等处理单位的输入、输出。
(热封性赋予方法)
在本实施方式中，也与第1实施方式相同，如图5所示的薄膜71那样对周缘的区域照射激光160而降低表面的结晶度，由此赋予热封性，构成密封部90。在图示的例子中，在被赋予了热封性的区域形成沿着激光160的扫描方向的加工痕迹80。
例如能够使激光160形成为点状光斑，通过将利用激光照射部130使光斑沿薄膜70的TD方向移动、和每次沿TD方向移动1行时便利用薄膜载置部140使薄膜70在MD方向上移动规定距离进行组合而进行扫描。另外，与第1实施方式相同，如图6所示的例子那样，使激光160的光斑形状形成为相对于TD方向以及与TD方向正交的MD方向的任意者不平行的、规定长度的直线形状的光斑S，在使得薄膜载置部140停止的状态下，利用激光照射部130绕薄膜的周缘的区域旋转1圈，由此能够对密封部90中的大部分区域进行照射。这样，通过适当地对激光160的光斑形状、尺寸、和激光照射部130、薄膜载置部140的移动进行设定、控制，能够适当地利用激光160在薄膜70的要赋予热封性的区域内进行扫描，特别是如图6所示的例子那样，如果将激光160的光斑形状设为为线段那样的具有延伸方向的形状，则在将不与延伸方向平行的方向设为光斑的移动方向的情况下，能够进行面扫描，因此能够不进行高速且复杂的控制地进行高效的扫描。另外，通过将衍射光学元件137配置为能够相对于激光160的通过方向旋转，能够容易地对光斑形状的延伸方向进行变更，能够容易地调整扫描区域的宽度。此外，薄膜70向薄膜载置部140的载置方向、激光160的扫描方向可以不依赖于MD方向、TD方向。
与第1实施方式相同，在本实施方式中利用赋予了热封性的薄膜能够制造例如图7所示的包装袋。
可以适当地对各实施方式的特征进行组合。例如，可以将第1实施方式中说明的各种光学元件用作本实施方式的光学元件。与使用氙气灯的情况相比，这种激光加工装置能够更安全且更高效地对双轴延伸聚酯薄膜赋予热封性。

利用能够以直径为0.14mm或14mm的点状的光斑形状照射波长为10.6μm的二氧化碳激光的激光振荡器20进行激光照射。利用采用了ATR(全反射测定法)的FT-IR(傅里叶变换红外分光光度计)对激光照射部位被照射的前后的吸光度进行测定并对结晶度的降低率进行计算，由此判定能否降低薄膜的结晶度而赋予足够的热封性。具体而言，在与照射前相比而使得结晶度降低了大于或等于30％的情况下，赋予了足够的热封性。
