Description

热楔式焊接装置
技术领域
本发明涉及一种用于搭接地焊接塑料幅(Kunststoffbahn)的热楔式焊接装置(Heizkeilschweissgeraet)，其带有：热楔，其具有在热楔后沿(Heizkeilhinterflanke)处开始的且在热楔前棱边处彼此相碰的两个热楔平侧(Heizkeilflachseite)且以热楔前棱边逆着在焊接时的运动方向取向地固定在由滚轮(Fahrrolle)支承的底盘(Fahrgestell)处，其中，热楔在塑料幅之间的搭接区域的焊接段中能够相对于其运动，以使焊接段塑化；带有用于塑料幅到热楔处的按压装置，其包括两个按压单元，其中的各个关联于热楔平侧中的一个；且带有两个彼此相对而置的压辊，被塑化的焊接段在焊接时在压辊之间穿过。
背景技术
带有可加热的热楔的这种类型的热楔式焊接装置以各种各样的实施形式中已知且常常尤其被用于塑料幅的自动的边缘侧的焊接连接。在借助于热楔搭接焊接塑料幅时，塑料幅在其接触面处被塑化且接着在压力作用下被焊接。通常，这两个可旋转地支承的压辊中的下面那个直接与底盘相连接而另外的上面的压辊经由夹紧臂(Spannarm)固定在底盘处，夹紧臂利用弹力将上压辊压向下压辊。在塑料幅在这两个压辊之间夹紧的情况下，由上压辊施加较高的夹紧力，其导致底盘的扭转，使得可旋转地支承的压辊不再精确地平行于热楔前棱边延伸，其中，上压辊(其在夹紧臂处通常支承在摇摆头(Pendelkopf)中)与下压辊的位置相匹配。这可导致在塑料幅的搭接区域中被塑化的焊接段的挠曲，这负面地影响塑料幅的焊接质量，因为热楔仅能以附加的力耗费匹配到搭接区域处。对于焊接过程，到搭接区域的焊接段上的该附加的力作用不是最佳的。
发明内容
从上述现有技术出发，本发明目的在于提出一种可能性，在其中热楔可无力效应地或以较小的力效应匹配于这两个压辊的相应的取向。
根据本发明，该目的通过一种带有权利要求1的特征的热楔式焊接装置来实现。另外的有利的实施形式可由回引的权利要求得悉。
对此，根据本发明的热楔式焊接装置具有热楔，其借助于至少一个轴承衬套(Lagerbuchse)可摆动地且因此围绕热楔的横轴线可倾斜地支承在轴承轴上，轴承衬套在这两个热楔平侧之间平行于热楔前棱边和热楔后沿分别有间距地延伸。根据该至少一个轴承衬套相对轴承轴的轴向长度，热楔可具有一个或多个轴承衬套，其彼此带有或不带有轴向间距地并排布置。两个平的盘形的轴承衬套证实为特别适宜的，其直接布置在侧向连接热楔平侧的热楔侧沿处。热楔在底盘处的这种固定使在结构上预定的自主的关于其横轴线的倾斜调节成为可能，其中，热楔此外可通过所设置的调整器件预调、尤其在热楔前棱边中的自动取向。通过使轴承衬套可关于轴承轴实施在轴承轴的周向上的受限制的旋转运动，热楔可自主地匹配于这两个压辊的相应位置。在此，热楔前棱边通过热楔的旋转运动精确地按照在这两个压辊之间的中间平面的高度、也就是说关于这两个压辊在垂直方向上取向。
原则上，平行于热楔前棱边延伸的轴承衬套可布置在热楔处的任意位置处。优选本发明的一实施方式，在其中轴承衬套尽可能中心地布置在热楔处、也就是说与热楔前棱边和平行于此地有间距地延伸的热楔后沿离得大约一样远。相对热楔的中心以热楔前棱边与热楔后沿的间距的最大大约百分之10布置轴承衬套证实为有利的。这引起，热楔后沿大约以与热楔前棱边上升相同的程度下降，或者当热楔前棱边下降时，相应地上升。因此薄膜幅在热楔运动时不被或几乎不被力加载且因此不期望地变形。理想地，因此热楔经由轴承衬套和轴承轴的支承精确地布置在热楔前棱边与热楔后沿之间的中间。
优选地，在根据本发明的热楔式焊接装置的热楔中，该至少一个轴承衬套具有相对轴承轴限定的轴向的和/或径向的自由度，使得热楔能够围绕其纵轴线翻倾并且/或者能够竖直地在按压单元的方向上移动。在翻倾的情况下，轴承衬套可在轴承轴的横向上实施受限制的径向的翻倾运动和受限制的平移运动。通常，轴承衬套的横截面形状和轴承轴的横截面形状在此可本身任意地来选择，只要其至少允许在轴承轴的周向上的摆动运动和相对热楔的轴承轴的纵向的翻倾运动。在此，轴承衬套和轴承轴的横截面形状在其轮廓及其尺寸上可相同或不同。也可能轴承衬套和/或轴承轴不具有在其长度上保持相同的横截面形状、而是在其横截面形状中关于纵向变化，其中，轴承衬套优选地朝向其端部扩开或轴承轴朝向其端部逐渐变细。
热楔的可翻倾性和/或可竖直移动性优选地通过轴承衬套和轴承轴的不同的横截面形状和/或长度来实现。通过热楔在轴承轴上的可倾斜的、可翻倾的和可竖直移动的支承，在该特别的实施形式中热楔前棱边的高度位置和倾斜位置可在规定的界限中任意改变。因此，由轴承衬套和轴承轴的彼此不同的外轮廓和/或彼此不同的尺寸决定，热楔的简单且无力的取向是可能的，以便达到由这两个压辊规定的高度尺寸或规定的角度尺寸，在其中至少热楔前棱边最佳地匹配于关于这两个压辊的位置。
根据本发明的一优选的实施形式，热楔通过轴承衬套关于轴承轴在横向上的轴向自由度可轴向移动一定的在结构上规定的量地支承在轴承轴上。在此，热楔此外通过轴承衬套相对于轴承轴在轴承轴的横向上的径向自由度可径向地在轴承轴上侧向地竖直翻倾。在一实施形式(在其中这两个热楔侧沿平地来实施)中，热楔在轴承轴上的侧向翻倾仅可能与轴承衬套关于轴承轴的轴向自由度相联系。
在另一有利的实施形式中，只要这两个连接热楔平侧的热楔侧沿至少在轴承衬套的区域中不是平地、而是例如凸球状地来构造，热楔在轴承轴上的翻倾在无轴承衬套关于轴承轴在轴承轴的纵向上的自由度的情况下也是可能的。其它情况仅当轴承衬套短于轴承轴时热楔在轴承轴上的翻倾才可能。
热楔的可能的翻倾方向相应于在通过上压辊夹紧塑料幅的搭接区域的情况下下压辊的可能的运动方向。下压辊被上压辊的夹紧力竖直加载且在相应的方向上被或多或少地偏转。相应地，热楔尤其可在热楔前棱边的高度位置中和在其倾斜位置中没有力地匹配于这两个压辊。
优选地，在根据本发明的热楔式焊接装置中轴承衬套构造有类似长孔的横截面形状而轴承轴构造有圆形的横截面形状，其中，在轴承轴之上和之下在轴承衬套与轴承轴之间分别构造有自由空间。由于存在的自由空间，热楔可在轴承轴上相对于水平的空间方向翻倾典型地大约5度以及竖直地移动。轴承衬套或轴承轴的相应反过来的实施形式也是可能的。在任何情况中，轴承衬套或轴承轴的类似长孔的横截面形状的主延伸方向相对于在这两个压辊之间的中间平面垂直，该中间平面正交于这两个压辊的旋转点的连接线延伸。主延伸方向平行于这两个压辊的旋转点的连接线，使得水平布置的热楔在横向上能摇摆地被支承且如此压辊侧沿可向上或向下关于这两个压辊运动。热楔从水平位置的可能的角偏转通过轴承衬套和轴承轴在竖直方向上的不同直径、也就是说通过轴承衬套的横截面形状的过长(Ueberlaenge)来确定。
可理解为根据本发明的热楔式焊接装置相对已知的现有技术的优点的是，热楔被支承成使得其可围绕其横轴线实施限定的旋转且可围绕其纵轴线进行限定的翻倾以及在这两个按压单元的方向上关于在这两个压辊之间的中间平面的垂直移动。因此，热楔可在无力作用的情况下匹配底盘的变形和与此相联系的这两个压辊相对水平线的翻倾。这一方面正面影响在焊接塑料幅时的焊接质量且此外使在焊接质量良好的情况下较高的焊接速度成为可能。因此确保热楔的位置总是精确地匹配上压辊和下压辊。

接下来根据在附图中示出的实施例来详细阐述本发明。本发明的另外的特征由本发明的实施例的接下来的说明结合权利要求和附图得出。本发明的各个特征可自己单独地或以多个在本发明的不同实施形式中来实现。其中：

图1显示了用于借助于热楔2(其被固定在由滚轮3支承的底盘4处)搭接地焊接塑料幅的根据本发明的热楔式焊接装置1的一实施例。塑料幅在图1中未示出。热楔2具有热楔前棱边5和热楔后沿6并且在焊接时以热楔前棱边5与热楔式焊接装置1的运动方向12相反地取向。热楔2(其在图1中部分被热楔盖板7遮盖)以其热楔前棱边5邻近下压辊8和上压辊9布置。下压辊8牢固地与底盘4相连接。上驱动辊9支承在摇摆头10中，摇摆头10布置在夹紧臂11处，夹紧臂又与底盘4相连接。热楔式焊接装置1在热楔2附件具有用于待焊接的塑料幅到热楔2处的按压装置，其包括用于未示出的塑料幅的搭接区域的被塑化的焊接段的两个按压单元13、14。图2以放大的图示显示了热楔式焊接装置1在热楔2周围的区域，而没有在图1中部分地遮盖热楔2的热楔盖板7。
如可由图2得悉的那样，下按压单元13将未示出的下塑料幅压向下部的热楔平侧15而上按压单元14将搭接的未示出的塑料幅压向热楔2的上部的热楔平侧16。此外，热楔2具有两个热楔侧沿17，其从热楔前棱边5延伸直至热楔后沿6且在热楔2侧面将上部的热楔平侧16与下部的热楔平侧15相连接。热楔平侧15、16彼此倾斜地且正交于这两个布置在水平的空间方向上的热楔侧沿17延伸。热楔2借助于支承部18被固定在底盘4处。支承部18在热楔2的纵向上大致布置在中间。
热楔2具有两个在附图3、4中示出的彼此有间距地对齐地布置的轴承衬套19和与轴承衬套19相关联的轴承轴21，轴承轴21从与底盘4相连接的热楔悬挂部20出发。轴承轴21和轴承衬套19形成对热楔2的支承部18。热楔2可摆动地支承在轴承轴21上且可围绕其横轴线实施限定的旋转。此外，热楔2可关于其纵轴线实施限定的翻倾和关于在这两个压辊之间的中间平面的垂直移动。因此，热楔2在轴承衬套19或轴承轴21的纵向上和横向上具有相对轴承轴21限定的自由度。由于轴承衬套19在轴承轴21的纵向上的自由度且由于轴承衬套19相对于轴承轴21在轴承轴21的横向上的自由度，热楔2可轴向和径向移动地以及可径向翻倾地支承在轴承轴21上。
图3再次放大地在纵剖面图示中显示了热楔2的支承部18。热楔2被串在柱状构造的轴承轴21上且利用涨圈(Sprengring)22防止从轴承轴21松开。对此，这两个彼此相对而置的热楔侧沿17分别作为轴承衬套19具有类似长孔的凹口23。类似长孔的凹口23在热楔2处取向成使得其主延伸方向在上部的和下部的热楔平侧15、16的方向上延伸。在横向于此的方向上，如图3所示，凹口23具有匹配于柱状轴承轴21的直径的尺寸。移除将轴承衬套19相对于轴承轴21的径向自由度限制到关于在这两个压辊之间的中间平面的垂直方向上。
相应于图4(其在横截面图示中显示热楔2的支承部18)，类似长孔的凹口23在这两个热楔平侧15、16的方向上构造得比柱状轴承轴21的直径更大。在轴承轴21与轴承衬套19(其由在这两个热楔侧沿17中的这两个凹口23形成)之间分别存在自由空间24，其使水平布置的热楔2能够在竖直方向上相应于自由空间24的尺寸翻倾。由此，热楔2可在纵向上和在横向上匹配于塑料幅的搭接区域的焊接段的由下压辊8和上压辊9确定的位置。由此确保热楔2总是具有相对上和下压辊8、9相同的最佳位置。
