Description
技术领域
本发明涉及一个用于多层介质、例如在过滤部件中使用的过滤无纺布的连接部件。本发明还描述了一个过滤部件、一个过滤装置和一种用于连接薄片状介质的方法。
背景技术
为了例如在汽车领域过滤流体如燃油、燃料或车内空气,经常使用折叠的或打褶的过滤无纺布。在此经常需要将这个薄片状过滤材料的不同棱边或端部段相互连接。已知的过滤部件例如由首先锯齿形折叠的过滤材料片制成,它们形成管状的基体。为了封闭管状的基体,必需使折叠段流体密封地相互连接。
对此过去例如使用金属别针或卡子,它们使两个相互排放的薄片状的段固定在一起。通常也将两个过滤材料片相互粘接或者仅仅通过压力或多次继续折叠使它们相互连接。尤其对于多层过滤介质、例如多层薄的浸渍的或具有特殊中间层的无纺布难以防止相互平放的棱边散线。特别困难的是,使要被连接的薄片状介质流体密封地相互连接,即,要被过滤的流体不允许在连接位置未过滤地通过过滤材料。此外必需使连接位置保持零件干净性。
发明内容
因此本发明的目的是,提供改进的连接部件,尤其用于端部折叠的过滤折子介质。
这个目的通过如权利要求1所述的连接部件得以实现。
因此建议一个连接部件,用于使薄片状过滤介质的至少两个端部段连接,该连接部件具有至少三个侧腿。在此分别在两个侧腿之间插入薄片状过滤介质的端部段并且通过热作用和/或压力使侧腿材料与过滤介质的材料连接。
也可以看作短臂或长形型材的筋的侧腿能够可靠地固定过滤介质,它们尤其通过加热作用在连接部位被侧腿材料包围或者局部地相互熔化。
例如所述侧腿可以这样薄片状地构成,使它们在两侧覆盖过滤介质的端部段。即,例如在连接两个薄片状的端部段时,存在侧腿材料、过滤介质材料、侧腿材料、过滤介质材料和侧腿材料的材料顺序。通过位于过滤介质之间的侧腿材料尤其在多层的薄片状过滤介质中实现它们相互间特别好的连接。
所述侧腿例如也可以在连接部件的公共棱边上汇合。在此能够分别使两个侧腿相互形成给定的角度。因此可以谈及扇形的连接部件。同样可以设想,所述连接部件具有E形的轮廓,其中在E的侧腿之间保留一个用于插入各过滤介质的端部段的中间空间。
在所述连接部件的一个实施例中,所述连接部件具有W形的轮廓并且由折叠的带构成。在W形轮廓中所述连接部件包括四个侧腿。由此能够使两个端部段出现在W形轮廓的外部相邻侧腿的中间空间里面。
所述连接部件最好具有热塑材料,例如热塑塑料。热塑塑料可以通过加热作用变形并因此提供在侧腿材料与过滤介质的材料之间的特别好的材料结合。例如可以通过加热的冲模、“激光焊接”、振动焊接、超声波焊接或热压加热热塑材料并由此形成与过滤介质材料的连接。
所述连接部件最好具有载体材料层和连接材料层,其中连接材料层的材料可以与过滤介质的材料连接。
例如可以这样构成所述连接部件,使连接材料层分别邻接过滤介质材料并且借助于加热、例如通过局部或完全相互熔化实现可靠的密封。
此外可以使所述连接部件的至少两个侧腿这样成形,使插入到两个侧腿之间的端部段通过夹紧封闭固定。这一点使加工过程中的连接部件与插入的过滤介质的加工和例如热连接变得容易。远离连接部件的公共棱边设置的至少两个侧腿的两个侧腿棱边例如彼此施加夹紧力。在此侧腿例如可以弧形地构成。
所述连接部件也可以具有多个通过侧腿之间的中间空间形成的插入口,由此可以插入多个要被连接的端部段。例如也可以将多层薄片状的过滤介质加入到各个插入口里面,然后通过连接部件相互焊接。所述侧腿例如矩形地成形,但是也可以具有其它的例如节省材料的几何形状。所述连接部件最好材料一体地构成,例如由唯一的塑料材料构成。
因此一个过滤部件具有薄片状的过滤材料,后者具有至少两个端部段,它们通过如上所述的连接部件相互固定。在此所述端部段可以源于唯一的、例如折叠的过滤材料片,或者也可以使多个过滤材料片相互连接。在此过滤介质也可以具有多个层,其中例如在层之间充满吸附材料如活性炭颗粒。
在所述过滤部件的另一实施例中所述过滤部件是用于汽车的燃料过滤器、燃油过滤器、空气过滤器或车内过滤器的一部分。
最后建议一个过滤装置,它具有一个相应的过滤部件并且由用于汽车的驱动剂过滤器、例如燃料过滤器、油过滤器或空气或内腔过滤器构成。
在一种用于连接薄片状过滤介质的至少两个端部段的方法中所述端部段分别插入到如上所述的连接部件的两个侧腿之间。然后加热侧腿材料和/或过滤介质的材料,由此使两个材料相互连接。同时实现过滤介质的相互顶靠的棱边流体密封的封闭。在此例如通过超声波焊接或激光焊接实现加热。
在一个方法变化中通过分别包围端部段的连接部件部分通过加热和/或相互连接形成连接部件。由此能够使连接部件两体地、例如以两个U形轮廓的形式构成,其中两个U形包围要被连接的端部段。通过连接两个U形轮廓的两个侧腿得到一个三腿的、与过滤介质的材料连接的连接部件。
本发明的其它可能的执行也包括未详尽列举的上述和下面的借助于实施例描述的特征或实施例的组合。在此专业人员也可以添加个性观点作为对于本发明各基本形式的改善或补充。
本发明的有利扩展结构和改进方案是从属权利要求以及在下面描述的实施例的内容。

在附图中相同或功能相同的部件,只要没有特殊说明,配有相同的标记符号。
具体实施方式
图1示出连接部件的第一实施例的立体图和横截面图。在图1A中示出两个薄片状的过滤部件2,3例如作为过滤材料片。为了使两个端部段在过滤介质的部位3A相互连接,使用E形的连接部件1。
在图1B中示出连接部件1的细节图,其中看到E形轮廓。对于E形轮廓备选地也可以在本发明的所有实施例中使用例如M形轮廓。例如由具有热塑特性的塑料制成连接部件。该连接部件1例如由聚丙烯材料构成,它具有约150至160℃的软化点。当然也可以设想其它热材料特性。匹配于各加工工艺和过滤介质以及应用范围地选择优选的塑料。
所述连接部件1可以由具有E形轮廓的塑料条构成,因此它具有三个侧腿1A,1B,1C,它们分别具有矩形的横截面。可以对应于过滤介质2,3选择侧腿1A,1B,1C的厚度。分别在两个侧腿之间,例如在侧腿1A与1B之间设有中间空间11A,在其中可以插入过滤材料2的端部段。此外在也可以称为筋的侧腿1A与1C之间也是一个中间空间11D,在其中可以插入第二过滤材料片3的端部段3A。
通过焊接或其它热应用实现过滤片的两个相互顶靠的端部段的封闭。所述过滤介质的端部段、例如塑料材料分别在两侧被连接部件1的塑料包围,由此得到特别好的固定封闭和可靠的连接,例如通过超声波焊接。尤其当过滤材料片已经具有多层的时候,也得到内部层相互间工艺可靠的连接。在此通过连接部件1的材料的熔化过程也可以使连接部件至少局部地挤入到过滤介质材料里面。由此避免层破碎,尤其也因为棱边10形成封闭。由此防止由于露出的纤维对零件干净性的不利影响。
图2示出过滤部件实施例的横截面图。例如过滤材料片经常折摺地折叠,即以锯齿形弯曲并且组成一个圆柱体。在图2中看到圆柱体轴线AX的俯视图或横截面图。该过滤部件4必需通过折叠的过滤材料构成,其中分别使两个端部段2A,3A在端部折叠棱边上相互连接。为此例如使用如图1所示的连接部件。因此该连接部件1使两个端部折叠棱边相互间流体密封地封闭。
相应的过滤部件4尤其在汽车过滤器中使用,例如用于油、燃油或空气过滤器。原则上能够在所有的过滤器形式中使用连接部件,在其中薄片状介质必需沿着一个棱边或段相互流体密封地连接。
在图3中示出例如过滤装置5的立体图。如图2所示,在此过滤部件4被下底板6例如粘接或者以别的方式相互连接。该底板6使由折摺的过滤材料2形成的过滤部件4圆柱体流体密封地封闭。通过环形板7形成上封闭,如同在图3中所示的那样,该环形板放置在过滤部件4的上折叠轮廓上。在此可以使上和下封闭板6,7焊接或粘接。如同已经对于图2解释过的那样,通过连接部件1流体密封地连接端部折叠段。因此得到过滤内腔8,流体可以通过上板7的孔挤入到内腔里面,穿过过滤材料2流动并且作为清洁流体流出。
在图4中示出连接部件的第二实施例。在此成形连接部件1的E形轮廓。该连接部件1具有用于侧腿1A,1B和1C的公共棱边10。设有一个中间的侧腿1A,它例如具有比外边的侧腿1B和1C更薄的厚度。在侧腿1A与1B之间的中间空间里面分别插入多层的过滤介质。在此示出第一过滤介质12和第二过滤介质13或相应的端部段。两个薄片状的过滤介质分别由两层12A,12B,13A,13B制成,其中分别在层之间分布活性炭颗粒14。由此改善过滤介质的过滤效果和吸附特性。
因为尤其这个多层的过滤介质12,13在其端部棱边上缝上,因此所提供的连接部件1特别好地适用。因为一方面得到棱边封闭10,另一方面在图4所示的内层13A,12B之间通过连接部件1的短臂或中间的侧腿1A实现更好的粘接或连接。例如能够简单地通过超声波或激光焊接至少短时间地加热侧腿1A,1B,1C并且带到熔化,由此使侧腿材料与过滤无纺布至少局部地连接。
在图5中示出连接部件的第三实施例。在此该连接部件9具有五个侧腿9A-9D,其中形成四个中间空间11A-11D,在其中可以加入要被连接的过滤介质的各端部段。这一点通过箭头P表示。例如可以使要被连接的多层过滤材料片插入到中间空间11A-11D里面。但是也可以设想,以确定的过滤部件形状使多个过滤材料片相互连接。通过连接部件的扩展结构分别在要被连接的过滤层之间得到材料段,它由侧腿材料组成。这导致所有要被连接的薄片状介质的特别好的连接。
在图6中示出在使用如上所述的连接部件的条件下连接薄片状过滤介质的方法状态的各个视图。图6A首先示出两个过滤材料片2,3,其端部段2A,3A相互连接。此外准备一个连接部件1,它具有多个侧腿,其中分别在两个侧腿之间出现一个插入口11A,11B。如同通过箭头P所示,现在将端部段2A,3A插入到插入口或中间空间11A,11B里面。
图6B以轮廓图示出过滤材料片2,3端部段插入到连接部件1里面以后的状况。接着加热这个部分,在其中过滤材料片的端部段出现在连接部件1的侧腿之间。这在图6C中示出。例如通过超声波射线US可以使过滤材料与连接部件材料焊接。也能够通过激光射线沿着连接部件的棱边、如同通过箭头US所示那样熔化材料层。
图6D示出例如在利用超声波焊接时的焊接过程。为此使用一个底座15B和一个上声波头15A,超声波以给定的频率或脉宽给出并且实现在材料层里面的热作用,即,以侧腿材料和过滤材料的顺序。
最后在图6E中示出过滤材料片2与过滤材料平3的端部段通过连接部件1的流体密封地连接。
在图7中示出用于连接部件和使薄片状过滤介质连接的方法的实施例的组合加工方法的变化。使两层薄片状过滤介质12,13的端部段2A,3A相互流体密封地连接。分别包括第一和第二层12A,12B,13A,13B的过滤材料片12,13的两个端部段2A,3A插入到U形的连接部件1A,1B里面。这一点可以在图7A中看出。各U形的平行侧腿位于端部段2A,3A的两侧。因此U形连接部件1A,1B包围端部段2A,3A。
接着如图7B所示,使连接部件1A,1B与插入的端部段2A,3A相互顶压。使两个连接部件1A,1B的两个侧腿相互顶靠。在图7B中看到,已经得到的连接部件1的E形形状,它通过连接部件部分1A,1B连接或焊接得到。
如同借助于图6D解释过的,接着使连接部件材料与过滤材料和连接部件部分1A,2A相互焊接。在图7C中示出这一点。可以看到与端部段2A,3A材料一体固定连接的连接部件1,它实现例如用于过滤折子缝的流体密封的连接。例如利用声波头15A和底座15B实现热连接。
图8示出连接部件的第四实施例的轮廓图。该连接部件17也在横截面中具有三个侧腿16A,16B,16C,它们在公共的棱边17上汇合。在各侧腿16A,16B或16A,16C之间出现楔形的开口或插入口11A,11B。由此侧腿16A,16B,16C基本直线地成形并且从公共的棱边17开始扇形地构成。通过例如可以分别调整的两个侧腿之间的角度可以容易地插入材料段。
图9示出连接部件第五实施例的轮廓图。该连接部件18具有四个位于公共棱边10上的侧腿18A,18B,18C,18D。在此两个侧腿18A和18C与棱边10的分段10A形成U形轮廓,其中侧腿相互弯曲。与分段10B一起形成公共棱边的侧腿18B和18D也形成U形轮廓,其中侧腿相互靠近地延伸。由此得到两个侧腿18A,18C的棱边20A或侧腿18D和18B的棱边20B相互间的弹性作用。因此通过上棱边20A和下棱边20B得到夹紧封闭。通过夹紧封闭例如可以固定插入到中间空间11A和11C里面的过滤材料段。
图10示出连接部件的另一实施例,其中通过侧腿19A,19B,19C的棱边20实现夹紧力。因此该连接部件19具有直臂的棱边10,从它基本中间地垂直于棱边10分支出中间的短臂或中间的侧腿19。两个外边的侧腿19B和19C这样从棱边10突出来,使远离公共棱边10的棱边20相互靠近地延伸侧腿19A,19B,19C或者例如也相互接触。由此实现棱边20之间的夹紧封闭。
在图11中还示出连接部件的实施例。图11A示出W形连接部件20的立体图,它由热塑材料带构成。该连接部件20包括四个侧腿20A,20B,21A,21B。在此设有两个外边的侧腿20A和20B和两个内部的侧腿21A和21B。通过折叠如同图11B所示得到两个相邻的沟或谷,在其中可以沿着在图11A中所示的箭头插入过滤材料片的端部段。
图11B示出例如由热塑材料制成的具有纵向折叠的带。在此虚线表示第一折叠方向,点线表示与第一折叠方向相反的第二折叠方向。通过折叠得到连接部件结构,如同在图11A中所示的那样。
图12A-12C示出相应的连接部件20的使用,如同在图11A中示出的那样。在W形轮廓的两个沟里面插入两个过滤材料片2,3的端部段2A,3A。一个内部侧腿21A,21B与外部的侧腿20A,20B形成一个沟或谷。接着使连接部件20的侧腿20A,20B,21A,21B与位于其间的端部段2A,3A挤压到一起。
如同在图12B中示出的那样,借助于超声波射线或其它加热和挤压可以使两个端部段2A,3A与连接部件20的材料相互连接。例如使用下底座15B 与声波头15A。在此(局部地)熔化连接部件20和过滤介质的材料。两个内部的侧腿21A,21B也相互间固定地熔化。由此如同12C所示得到与图6E和7C中类似的相互流体密封的封闭的端部段结构。
最后图13还示出一个用于连接过滤材料段的连接部件22的变化。在此该连接部件22具有两层。第一载体层22A例如作为用于第二连接材料层22B的稳定载体,它具有可以熔化的材料。连接材料层22B由通过加入能量变软的材料构成并且可以挤入到过滤介质里面。相应的双组分实施例也可以设想用于其它几何形状。面对过滤介质的连接部件一侧最好仅仅配有相应的连接材料层22B。
因此提供一种简单的可能性,尤其使端部无折叠折子配有流体密封的缝或连接。所建议的方法能够方便地在加工工艺中执行,并且连接部件可以容易地符合标准地制成。
