Description
技术领域
本发明涉及一种用于制造带材的方法,所述带材通过将至少两个单体带材在纵侧焊接而制成。
另外,本发明还涉及一种用于借助焊机和至少一个用以移动带材的驱动装置制造由至少两个单体带材纵向焊接而成的带材的设备。
此外,本发明涉及一种由单体带材通过焊接制成的带材。
背景技术
在薄膜、特别是例如用于生产LCD显示屏的三醋酸薄膜的制造当中,应用循环带材,这样的薄膜被设敷于所述循环带材上。制造较大的显示屏同样也需要使用较宽的循环带材。在提高制造薄膜材料过程中的生产效率方面考虑,使用较宽的带材也是有利的。由于用以制造循环带材的原料带材的带材宽度通常为约2m,为了获得更大的带材宽度,要将两个或更多个原料带材在它们的纵侧的边缘上相互焊接在一起。通常是在水平平面内进行这样的纵向焊接。为此,根据现有技术,缠绕在辊上的原料带材被并排展开并且依带材纵长方向沿着它们的纵向边缘被相互焊接在一起。在这种情况下,焊缝沿水平方向被引导。例如由US3728066已知一种这样的方法或者这样的带材。然而该已知方法的缺点是:由于带材或者焊缝引导在焊接过程中的水平定向,在所产生的焊缝中会形成由于重力造成的不对称。因为用于制造薄膜的纵向焊接的带材的表面必须构造得尽可能均匀并且不应该具有不平度,所以这一点是特别成问题的。而在焊缝不对称的情况下,在后续的诸如研磨的加工工序中,由于材料去除量的不均等而可能导致带材表面中的不均匀性。
发明内容
因此,本发明的目的就是实现由单体带材制造出宽的带材,其具有最佳的表面特性。
根据本发明,上述目的利用文首述及类型的方法通过如下方式得以实现:在焊接之前将各单体带材的局部区段转向到竖直方向,其中,带材的转向后的局部区段沿竖直方向被引导经过至少一台焊机的焊接机头并被该焊机相互焊接在一起。
在此需要说明的是:在本文件中,所说竖直的概念是指基本上与地球表面成直角定向的或者说指向地心的方向。因而,竖直的概念就此方面来说被赋予“基本上铅垂”的意思。然而必须指出的是:相对于铅垂方向有微小的偏差并不影响本发明的方案,这种情形在此当然同样属于所说“竖直”的概念。
通过焊缝的竖直布置,在焊接过程中产生的熔体由于重力的原因可以均匀分布并因此可以获得对称的焊缝。基于焊缝的对称性,在后续的研磨过程中也保证了均等的材料去除量。因此,除了加工得以简化之外,还大大地提高了由纵向焊接的带材所制成的循环带材的表面质量。
本发明的一个有益的变型方案规定:带材的转向到竖直方向的局部区段的彼此面对的、要相互焊接在一起的边缘借助转盘被驱向相对聚拢,其中,每个带材配置有至少一个转盘,该转盘朝另一带材的方向倾斜。按这种方式,可以在焊接位置的区域中缩小在要相互焊接到一起的带材之间存在的缝隙并因此对焊接过程产生有利影响。在这种情况下被证明是特别有益的是,每个转盘仅仅在与要焊接的纵向边缘邻接的区域内贴靠在配置于它的带材的表面上。
根据本发明的一个特别有益的变型方案,可以规定:要相互焊接在一起的单体带材在转向到竖直方向之前从彼此相反的输送方向被引向相对聚拢。本发明的这一实施方式保证了两个单体带材的最佳带材延伸走向。通过这种设置,还能够消除(带材)在向焊接位置水平输送过程中相互间由于带材的运动而引起的干扰,如同它们在带材并排布置的情况中在向焊接位置或者向一个设置于焊接位置之前的往竖直方向进行转向的转向装置的输送过程中可能出现的那样。
根据本发明,上述目的还可利用文首述及类型的设备通过如下方式得以实现:所述设备具有至少一个转向装置,通过该转向装置,各单体带材在经过焊机的焊接机头之前被转向到竖直方向并且沿竖直方向以及在一个共同的平面内延伸地被引导经过所述焊机的焊接机头。
本发明的设备的一种有益的发展设计规定:要相互焊接在一起的单体带材的输送方向在经过所述至少一个转向装置之前是彼此相反的。
本发明的一个优选的变型方案规定:该设备在所述至少一个转向装置与焊机的焊接机头之间具有至少两个转盘,这些转盘相对单体带材的表面朝这些带材的要相互焊接在一起的纵向边缘的方向倾斜地设置。在这种情况下特别有利的是:转盘围绕它们的旋转轴可自由旋转地设置。
本发明的特别有利的发展设计在于:焊机为激光焊机。尽管本发明的方案并不局限于使用激光焊机,而是也可以使用其他的焊接方法,诸如钨极惰性气体保护焊(WIG焊)、熔化极惰性气体保护焊(MIG焊)/熔化极活性气体保护焊(MAG焊)、超声波焊接或者摩擦搅拌焊接,但是使用激光焊机具有焊缝形状细而长的优点。这一点就此而言被视为是特别有益的。
根据本发明的方法或者利用本发明的设备制成的带材具有宽度大和焊缝对称的优点。这样的带材能够特别有利于进一步加工成具有高度均匀的结构和表面性质的抛光的循环带材。
附图说明
下文将参照附图中所示出的几个非限制性的实施例进一步阐述本发明以及更多的优点。
在大大示意性简化的附图中分别示出:
图1为本发明的设备的侧视图;
图2为焊接区域沿图1中的方向V的视图,其中未示出转盘用的保持架;
图3为设置在竖直的带材延伸走向区域内的、与带材配合作用的转盘的进一步的详图;
图4为图1所示出的设备的一个区域的由方向VI看的俯视图。
具体实施方式
作为引言首先要说明的是:在不同描述的各实施方式中,为相同的部件/部分配置了相同的附图标记或者相同的构件名称,其中,在说明书全文中所包含的公开内容都可以按照意义转用到配有相同附图标记或者相同构件名称的相同的部件/部分。再者,在说明书中所选择的位置说法,如上、下、侧面/侧向等等,都是相对于直接描述以及示出的附图而言的,并且当位置变化时,可按照意义转至新的位置。此外,图示的及描述的不同实施例中的单个特征或者特征组合也可能是独立的、有创造性的或者根据本发明的解决方案。同样还需指出的是:各附图是被作为整体一般性说明的。
根据图1,本发明的用于焊接两个单体带材2、3的设备具有一台焊机6,该焊机以优选的方式构造成激光焊机。尽管在此仅仅示出一台焊机6,还是可以对带材2和3实施双侧焊接。在这种情况中可以设置两台或者更多台焊机。在此,焊机可以设置在带材2和3的相对的宽面处并在必要时还可以同时将两个带材2和3相互焊接在一起。通过焊机在两侧的布置方式,可以实现更加对称的焊缝。在此处示出的实施方式中,带材2和3可以从辊4和5上展开。辊4和5可以分别借助一个驱动装置例如用于使带材2和3移动的、轴向设置的马达沿它们的输送方向I和II被驱动。另外,带材2和3也可以沿它们的输送方向I和II被牵拉。为此可以设置一个受驱动的辊8,由两条带材2和3借助焊机6焊接在一起的带材7被缠绕在该辊上。
为了使带材2和3转向进入到竖直方向III,设备1具有转向装置14和16。转向装置14、16例如可以构造成转向辊。
根据本发明的通过单体带材2、3在纵侧焊接来制造带材7的方法,单体带材2、3的局部区段在其焊接之前由它们的输送方向I和II被转向到竖直方向III。带材2、3的经转向的局部区段沿竖直方向III被引导从焊机6的焊接机头旁边经过并被该焊机彼此焊接在一起。在此方面值得一提的是:两个带材2和3的彼此相对的纵向边缘被如此地相互焊接在一起,即,产生一个表面齐平的带材7,该带材通过焊缝13接合在一起。由于带材2和3在焊接区域内的竖直布置,熔化的材料可以对称地凝结。由此形成的焊缝13的出众之处在于其非常对称的结构。
如从图1和4中可以看到的那样,两个带材2和3以优选的方式在它们借助转向装置14或16转向之前从彼此相反的输送方向I和II相对聚拢地移动。在转向到竖直方向之后,两个带材2和3处于一个共同的平面内,其中,两个带材2和3的移动方向在转向之后彼此平行地延伸。如从图4中另外可以看到的那样,两个带材2和3是在侧向相互错开的,因而它们在转向之后并不直接并排布置。
在带材2和3被焊接成带材7之后,可以设置另一个转向装置15,例如同样是辊的形式,该转向装置将带材7继续引向辊8。
在焊接位置的区域内,设备1可以具有转盘,这些转盘在图2中标注以附图标记9、10、11、12。而在图1中只能看到两个转盘11和12。转盘9、10、11、12能够围绕其旋转轴可自由旋转地固定在保持架17上,该保持架例如可以设置在此处未示出的机架上。在图2的视图中,为了更好地描绘转盘的作用原理而未表示出该保持架17。
不同于在图2中示出的本发明的变型方案,每个带材2和3也可以设置至少两个彼此相对的转盘。也就是说:在带材2或3的两个相对侧的每一侧上可以各设置至少一个转盘,其中,这些转盘以优选的方式彼此精确地相对置。
带材2、3的转向到竖直方向的局部区段的彼此面对的、要相互焊接在一起的边缘借助转盘9、10、11、12被驱向相对聚拢(亦即被相向驱动)。在这种情况下,与一个带材2、3接触的转盘9、10、11、12可以向另一带材2、3的方向倾斜。也就是说:转盘9、10、11、12的旋转轴朝两个带材2和3之间的缝隙的方向倾斜。如在图3中所示出的那样,如果每个转盘9、10、11、12仅仅在与要焊接的纵向边缘邻接的区域b内贴靠在配置于它的带材2、3的表面上,则是特别有益的。根据图3中的视图,转盘12在它距带材2的要焊接的纵向边缘较远的区域处与带材表面保持有距离。这些距离在图3中用附图标记a和c标出。
转盘9、10、11和12通过两个带材2和3的向下移动被驱动。通过由此产生的转盘9、10、11和12的旋转运动,两个带材2和3被驱向相对聚拢以及该两个带材2和3的要彼此焊接在一起的纵向边缘之间的缝隙变小,通过这种方式可以达到在带材2和3之间用于焊接过程的最佳距离。
纵向焊接好的带材7可以送到其他的后续加工工序,诸如加以研磨和/或抛光。
实施例示出了本发明方法或者本发明设备的一些可能的实施变型方案,在此需要注意的是:本发明并不局限于其特别示出的这些实施变型方案,而各个实施变型方案相互进行各种不同的组合也是可能的,并且,基于通过具体发明对技术措施的教导,这些变型可能性是处在本领域技术人员的能力范围之内。
因此,所有可以想到的(通过将所图示和所描述的实施变型方案的单独细节组合起来能够实现的)实施变型方案也都包括在保护范围之内。
为规范起见,最后还要指出的是:为了更好地理解本发明设备的构造结构,该设备或者其组成部分是部分地未按比例和/或放大和/或缩小地示出的。
