Description

用于接合至少部分重叠的材料层的方法及用于执行该方法的 自动接合装置
技术领域
本发明涉及一种用于可焊接和/或可粘合的平面柔性材料层间的热致式接缝接合的方法，其中，该材料层为卷材(material web)、带材(material band)和/或片材(material piece)，使用自动接合装置将材料层设置为至少部分地重叠，使用设置在该自动接合装置的托架处的至少一个电接触加热装置，其具有直接电动的可加热的加热楔，把至少一个要接合的材料层局部加热至接合温度，和使用设置在自动接合装置的托架处的至少一个接触式压料辊该压料辊，其由电动机驱动，局部压缩材料层中的已加热的材料部分。在该过程中，一直使用电子控制器以用于调节和/或控制材料层和自动接合装置之间的相对速度v以及设置在加热楔的两个电极之间的加热电阻器的温度T和/或电功率P。
本发明还涉及一种用于可焊接和/或可粘合的平面柔性材料层间的热致式接缝接合的自动接合装置，材料层为卷材、带材和/或片材，并且设置成至少部分重叠，自动接合装置配置为在重叠处执行上述方法。
背景技术
本领域中已知的是通过热楔物焊接方法，将箔和来自热塑性合成材料及涂覆有热塑性合成材料的织物的密封材料卷材，在重叠边缘处进行彼此接合，特别是将它们密封在一起。因此，通常要对局部塑化要连接的合成材料卷材的加热楔进行直接或间接地加热。此外，把片材或带材与由热塑性材料制成或者由热塑性材料涂覆的材料层接合，也是已知的。再此外，用热楔物粘合方法，而不是焊接方法，来粘合材料层，也为已知的。因此，通常将可热熔(thermally activable)的胶层涂覆到待接合的材料层的其中一层的指定的连接部分上，其中胶层由热楔物熔化。
在本领域中，用于执行热楔物焊接方法的多种焊接机或自动焊接机形式的自动接合装置是已知的。所使用的所有已知的装置和方法的共同之处在于，待焊接的材料在其边缘被抬升，并且彼此相向定向的表面被热的加热楔所塑化，并随后被接触压辊用足够的力按压在一起。在本领域中，用于执行热楔物粘接接合方法的多种粘合装置或自动粘合装置也是已知的。在这些已知的装置和方法中，待连接的中间层也局部涂覆有热熔胶，并通过加热楔加热，直到胶被塑化，然后由接触压力辊用足够的力进行压缩。
这种类型的焊接缝或粘接缝必须是长期密封的和/或具有足够的强度。众所周知，通过热楔物法生产的连接缝的质量高度依赖于所使用的工艺参数。对于安全的接合连接，特别地，速度是相关的，通过其加热楔沿材料层移动，还有加热楔的温度，其加载待连接的材料部分的温度，以及接触压力，其是由接触式压料辊施加在待连接的材料部分上的压力。这些重要的工艺参数在自动接合方法中通常被自动监测和控制。为此目的，提供了用于检测加热楔的温度、焊接速度以及接触压力的装置，其通过集成的装置控制器使显示参数和调整及改变参数更加容易。
关于根据热楔物接合方法连接材料层的现有技术方法和装置，参考专利申请公开文献EP 1 464 471 A1。此外，用于实现热楔物接合方法的不同加热楔也是已知的，例如，在公开文件US 2,870,308A，DD 49 995 A1和DE 10 206 016 695 A1中。
所使用的加热楔具有相对较大的质量，被认为是已知的自动加热楔结合装置及其接合方法的一个缺点，这阻碍了在焊接过程中通过加热楔的温度或功率的必要调整来快速加热和冷却加热楔，而为了确保稳定的焊接质量，这却是需要的，例如，由于焊接期间发生的速度变化。
发明内容
基于这些发现，本发明的目的是提出一种选择，使直接电动加热楔快速响应于由塑料材料和自动接合装置之间相对速度的变化而触发的电功率调节。
根据本发明，该目的通过具有独立权利要求1中特征的方法来实现。该目的还通过具有独立权利要求11的特征的自动接合装置来实现。本发明的其它优选实施方式可以分别自从属专利权利要求得到。
相应地，根据本发明的用于可焊接和/或可粘合的平面柔性材料层彼此间的热致式接缝接合的方法，材料层为卷材、带材和/或片材且设置为至少部分重叠，在接合过程中，至少在预设的时间间隔内监测材料层与自动接合装置之间的相对速度v以及加热楔的温度和/或电功率。其中，当相对速度v的变化被检测到时，加热楔的电功率P会根据检测到的相对速度v进行自动调整。这样，在相对速度v的增加期间，加热楔的电功率增加；在相对速度v的降低期间，加热楔的电功率减小，从而使得加热楔的温度或从加热楔传递到材料层连接部分的热能的量独立于相对速度v保持恒定。该方法可用于可移动的以及固定的自动接合装置，其中，本质上是加热楔传输到材料层接合部分的热能的量保持恒定，而不是加热楔的温度。本文中的相对速度v是可移动的自动接合装置相对于材料层的移动速度或材料层相对于固定的接合装置的移动速度。
在根据本发明方法的一种优选实施方式中，传递到待连接的材料层的热能的量保持恒定，而与相对速度v无关。这尤其意味着，对于任意的相对速度，加热楔传输到材料层连接部分的热能都是相同的。这也就意味着，材料层或材料层的胶层的塑化是持续进行的。为了达到这个目的，选择加热电阻器的电功率P作为材料层和自动接合装置之间的相对速度v的函数，这意味着当相对速度v变化时，它将被分别重新调节，其中，在相对速度v的增加时，加热楔的电功率P增加；在相对速度v的降低时，加热楔的电功率P减小。
优选地，加热楔的加热电阻器的电功率P由电子控制器来控制，因此功率P的实际值PI相对于功率P的标称值PS保持恒定，其中用户可以优选预先确定功率P的至少一个标称值PS。因此，在接合过程中，至少在预定的时间间隔内，相对速度v和加热楔的电功率是自动确定的。在检测到相对速度v时，如果实际值PI与标称值PS存在偏差，电子控制器会立即自动补偿该偏差。
在本发明的一种优选实施方式中，加热电阻器的功率PI通过测量加热楔的电极处的电压下降以及通过测量流经加热元件的加热电阻器的电流来确定。这有助于以简单的方式精确地确定加热电阻器的电流功率P。由此，检测到的实际值PI和预定的标称值PS之间的较小偏差也可以被可靠地确定。
在根据本发明的方法的一种实施方式中，电功率P的标称值PS被电子控制器在内部分隔成可用于焊接或粘合过程的标称值部分PSn和不能用于焊接或粘合过程的标称值部分PSv。功率损耗PSv是楔形物与楔形接合几何结构的函数。
在根据本发明方法的一种优选实施方式中，标称值部分PSn由电子控制器根据加热楔的能量密度的标称值EDSn、加热楔相对于材料层的相对速度以及加热楔的宽度B来内部确定，其中标称值部分PSn是加热楔的能量密度的标称值EDSn、相对速度v以及宽度B的乘积。
保持能量密度恒定有助于使焊接或粘合接合的质量特别均匀。能量密度是传递到材料上的能量的量度，因此也是能量传递后材料温度的量度。对于每种材料，都有其最佳的能量密度，这使得能够实现最佳的接缝质量。通过能量密度EDSn和不可使用的标称值部分PSv，待焊接和/或粘合在一起的材料层的材料性质和加热楔或者胶的特殊属性都得到了考虑。
电子控制器通过测量加热装置的电压下降和流经加热装置的电流来确定接触加热装置的电功率。相对速度v，即接合速度，是通过例如由电动机驱动的至少一个压料辊的驱动单元的速度来确定的，并且加热装置的宽度由用户确定并输入至电子控制器。
此外，已证明为特别有利的是，在根据本发明方法的一种实施方式中，至少加热楔的功率P的标称值PS、加热楔的功率P的不可用标称值部分PSv和/或能量密度的标称值EDSn是由自动接合装置的用户预先确定的。由此，加热楔的功率可以适应于不同材质和/或厚度的待彼此接合的材料层，和/或不同的楔形物以及楔形连接几何结构，尤其是，在焊接和/或粘合过程之前，可以适当地对功率进行调节。
优选地，在上述方法的一个实施方式中，至少在实际接合过程之前的加热电阻器预热期间，通过电子控制器对加热楔的温度进行调节和/或控制。特别地，为了确定加热楔的温度，对加热电阻器的温度依赖性电阻进行测量。因此，优选的是，通过测量电极处的电压下降并通过测量流经加热电阻器的电流来确定加热电阻器的电阻。由此可以根据需要来测量和调整加热电阻器的当前温度。
电子控制器判断直接电动可加热型加热楔的温度依赖性电阻R，并控制温度依赖性电阻R，从而使值R相对于标称值RS保持恒定。这种类型的控制优选地仅用于预热，也就是在实际的焊接或粘合过程之前的几秒钟。确定了的电阻值也可以任选地转换成温度值，这样还要使用预先获取的电阻温度图。
用于可焊接和/或可粘合的平面柔性材料层间的热致式接缝接合的自动接合装置，材料层为卷材，带材和/或片材且由热楔物焊接或热楔物粘合设置成至少部分重叠，包括电子控制器，其配置为实施上述方法。如本领域已知的，电子控制器包括至少一个设置在该接合装置的托架处的电加热装置，该电加热装置包括用于边缘焊接材料层中的至少一层和/或用于熔化设置在至少一个材料层上的胶水的直接电动加热楔，并且还包括至少一个接触式压料辊，该压料辊由电动机驱动且设置在托架处，用于在对预定的接合部分进行局部加热后压缩待连接的材料层。该电子控制器用于调节和/或控制材料层和自动接合装置之间的相对速度v，并且用于调节和/或控制设置在加热楔的两个电极之间的加热电阻器的温度T和/或电功率P。这样，加热电阻器由折叠的钢板坯料形成，该折叠钢板坯料的折扭形成加热楔尖端，而其平行于折扭的伸出的边缘则附接在两个电极处。根据本发明的自动接合装置可以是接合装置相对于材料层移动的自走式自动接合装置，或可以是材料层相对于接合装置移动的固定式自动接合装置。
优选地，钢板坯料包括在电极之间延伸的曲折切割绕组。曲折切割绕组决定了加热电阻器的有效长度和宽度。钢板坯料的曲折切割绕组的几何形状及钢板坯料的制作材料决定了加热电阻器的耐寒性和耐热性。
为了加快电阻器的反应时间，钢板坯料的质量较小。为实现此目的，特别地，钢板坯料的厚度在0.1mm和1.0mm之间，和/或加热电阻器的最大质量不超过50g。
在根据本发明的自动接合装置的一种优选实施方式中，加热电阻器配置为凹形，优选地两侧都设置成凹形，特别是在朝向至少一个接触式压料辊的前端部分中。该部分中的加热电阻器尤其具有与至少一个接触式压料辊相同的曲率半径。这有助于通过接触式压料辊的位于加热电阻器处的外圆周，使经过加热楔的材料层在被接触式压料辊压缩之前与加热楔保持接触，这对材料层的加热有积极影响。
在根据本发明的自动接合装置被配置为自动焊接或粘合装置的一种优选实施方式中，提供有用可调节的力将接触加热装置压靠至少一个接触式压料辊上的装置。因此，待焊接或粘合在一起的材料层的待连接部分被夹紧在加热楔和至少一个接触式压料辊之间，并因此被压靠在加热楔上，这有利于加热材料层。
加热楔在安全的低电压范围(SELV)下操作，并且根据最多30-50V的适用标准直接加载电流。
本发明的用于根据热楔物接合方法将可焊接或可粘合的材料层缝接接合的方法具有以下优点：接合速度在接合过程中可以被改变，这意味着随意增加或减少而不会使形成的焊接或粘接缝的质量变差。取得该优点的原因是：通过改变待连接的材料层和接触加热装置之间的相对速度，也使加热电阻器的电功率通过自动接合装置的控制电子设备自动适应性改变，其中，控制电子设备改变了加热电阻器的电功率，从而使得传递给材料的热能独立于相对速度而保持恒定，也即是独立于焊接或粘合速度而保持恒定。本发明为用户，客户以及制造商都提供了许多有利之处。例如，加热楔由于其质量较小在功率变化时提供了快速反应时间，从而使得有利于快速加热和冷却以及在接合过程中功率或速度的适应性改变。此外，该加热楔便于达到较高的表面温度，并因此特别适合于以较高速度接合涂覆型材料。该加热楔可以通过符合成本效益的方式生产，这样就相应实现了较低的生产成本。此外，不需要温度传感器来检测加热楔温度，在其中温度传感器容易受到磨损和腐蚀。
另外一项优点是，加热功率能够通过调节能量密度来自动地适应于速度，这对接合缝的质量具有积极的影响。
此外，由于采用低安全电压，使得接触加热楔不会产生任何风险。进一步地，当操作电压关闭时，加热楔能够快速冷却，使得在待机操作(stand by operations)期间意外接触加热楔不会导致烫伤。
根据本发明的自动接合装置可以用于塑料材料卷材或箔的边缘接合，用于商业横幅或卡车卷帘的边缘接缝或用于在这种类型的材料层上添加加强贴片。另一个应用是所谓的3-D焊接或3-D粘合，其中合成材料箔和油毡的坯料沿着它们的接缝与材料基底网结合。由此，例如可以像缝纫机一样将充气船或运动夹克接合。另一种应用是在材料层上施加带，这是指通过直接焊接或用例如热活化胶粘接把所谓的胶带与任何基础材料进行连接，例如，为运动服装的缝制接缝的缝密封而涂覆胶带。
