Description

用于包装材料的成形环
技术领域
本发明总体上涉及包装机***以及用于在这种***中将包装容器成形和密封的装置的领域。更具体地说，本发明涉及用于包装材料的成形环，用成形环使包装材料成形和密封包装材料的方法，以及具有这种成形环的填充机。
背景技术
在包装机***的领域中，存在用于将包装材料成形为包装容器并密封包装容器的各种装置和方法。具有液体内容物的包装容器可以根据使包装材料幅材基本向下移动通过填充机的原理来制造，其中幅材在成形环中被转换成包装材料管。该管围绕填充器管形成并且连续填充预定的内容物。在填充机的底端，进行已填充管的逐渐密封，以顺序地生产其经填充的包装容器。首先将管状结构的包装材料在填充液体内容物之前沿纵向方向(即在管延伸并传送管的方向)通过密封装置进行密封。典型地，在填充机中，压力辊可旋转地设置在管状包装材料内并且压靠管状包装材料的纵向接合表面，并且配对辊可旋转地设置在管状包装材料外部的成形环处，以接收由压力辊施加的压力。因此，当包装材料行进时，压力辊和配对辊夹紧包装材料的纵向密封表面并对其进行密封。
用于使包装材料成形为管状结构和用于提供纵向密封的先前的解决方案可导致褶皱的包装材料，其可能危及密封的质量。特别是当包装材料具有更复杂的开启机构时可能会出现这种情况。而且，纵向密封表面之间的搭接部分的量可以沿着纵向方向变化，这也可以是间歇性非优化密封包装容器的原因。在高速填充机中检测有缺陷的密封非常麻烦，并且可能会限制生产线的生产量。褶皱的包装材料也可能影响包装材料的后续折叠过程，引起生产线下方的问题以及成品包装容器的可能的完整性问题。
因此，改进的成形环、用成形环使包装材料成形和密封的方法以及具有这种成形环的填充机将是有利的，并且特别地允许避免更多上述问题和损害，包括减少包装材料褶皱、包装容器密封不良或完整性问题的风险。

具体实施方式
本发明的具体实施例现在将参考附图来描述。然而，本发明可以许多不同形式体现，并且不应当被理解为限于本文所示的实施例；相反，提供这些实施例使得本公开将是充分和完全的，并且将本发明的范围完全传达给本领域技术人员。用于附图中示出的实施例的详细说明中的术语不旨在限制本发明。在附图中，相同的数字是指相同的元件。
图1是用于将包装材料成形为管状结构的成形环100的示意图。成形环100包括旋转成形构件101，旋转成形构件101可旋转地布置成限定用于将包装材料成形为沿纵向方向103延伸的管状结构200的开口102。开口102在图3以透视图或者在图4以俯视图示出。旋转成形构件101布置在成形环100的第一平面104中。图2是成形环100的侧视示意图，示出了布置在平面104中的旋转成形构件101。成形环100包括至少一个密封构件105,106，所述至少一个密封构件105,106配置成在使用中在开口102中使包装材料成形为管状结构200后密封管状结构200的纵向接合表面201,201'。如图2所示，至少一个密封构件105,106被布置成在纵向方向103上相对于第一平面104在偏移距离107处。通过将至少一个密封构件105,106布置成相对于第一平面104(在该第一平面104中布置有成形构件101)在偏移距离107处，将包装材料成形为管状结构200不干涉纵向接合表面201,201'的密封。因此，在通过旋转成形构件101进行的成形步骤期间发生的由于纵向接合表面201,201'的位移而导致的对密封的任何有害影响可以被最小化。因此可以避免包装材料(例如，在纵向接合表面201,201'之间的密封界面处或附近)的缺陷或变形，并且可以使密封更可靠。这在包装材料于成形为管状结构200之前设置有开启机构时是特别有利的，因为这种开启机构当其被旋转成形构件101接合时可能会增加纵向接合表面201,201'的搭接部分中的瞬时波动量。这在图5a-b中进一步示出，其以俯视图示意性地示出了成形环100的一部分。在图5a中，包装材料的管状结构200布置在开口102中，在纵向接合表面201,201'之间具有限定的搭接部分(L)。至少一个密封构件105在限定的搭接部分(L)的位置以虚线示出。一旦管状结构200的厚度增加的部分203到达开口102，纵向接合表面201,201'的搭接部分增加，如图5b所示，因为在径向方向110上添加的材料径向向内推动包装材料。在图1的示例中进一步示出的增加厚度的部分203可能由从包装材料突出的开启机构(例如注塑开启机构)提供，由此增加了管的沿径向方向110的厚度。通过将至少一个密封构件105,106布置成相对于第一平面104(在该第一平面104中布置有成形构件101)在偏移距离107处，当厚度增加的部分203到达至少一个密封构件105,106时，由于先前由成形构件101在第一平面104位置处施加的径向约束已被去除，所以纵向接合表面201,201'的搭接部分会再次呈现图5a中所示的限定的搭接部分(L)。因此，纵向接合表面201,201'的临时位移对包装材料密封的由厚度增加的部分203引起的影响最小化。因此，即使密封包装材料在其表面上具有预成型结构(例如在径向上延伸的开启机构)，也可以避免沿纵向接合表面201,201'在包装材料中形成皱褶或其他缺陷。特别地，在一些应用中，包装材料设置有开启机构，该开启机构沿着包装材料的护套(sheath)的除了纵向接合表面201,201'之外的整个宽度延伸。在这种情况下，厚度增加的部分203可以围绕管状结构的除了发生密封的扇区206之外的直径的大部分延伸，如图5b示意性所示，以及对于纵向接合表面201,201'之间的搭接部分的影响将增加。因此，在这种情况下，将至少一个密封构件布置成相对于第一平面在偏移距离107处会是特别有利的。因此可以改善纵向密封过程的可靠性，因为可以减少由于纵向接合表面201,201'的搭接部分的波动而获得有缺陷的密封的风险。
如图4的示例所示，旋转成形构件101可以设置成环形结构。包装材料输送通过由旋转成形构件101的环形布置限定的开口102，从而限定所形成的管状结构200的直径。旋转成形构件101的数量可以改变，从而其布置可以改变，并且图4所示的结构仅是这种结构的示例。可以进一步想到的是，管状结构的形成由其他成形元件提供，不一定是以环形结构布置的旋转成形元件101提供。
图6示出了用成形环100使包装材料成形和密封的方法300的流程图，成形环100具有可旋转地布置以限定开口102的旋转成形构件101。描述和说明方法300的步骤的顺序应该不应被解释为是限制性的，并且可以想象的是，这些步骤可以以不同的顺序执行。方法300包括通过沿着纵向方向103输送包装材料通过开口102而使包装材料在开口102中成形301为管状结构200。方法300还包括在开口102中使包装材料成形为管状结构200之后，用至少一个密封构件105,106密封311管状结构200的纵向接合表面201,201'。因此，方法300提供了有利的包装材料的成形和纵向密封程序，如上所述。
如所描述的，旋转成形构件101可以布置在成形环100的第一平面104中，并且至少一个密封构件105,106可以布置成沿纵向方向103相对于第一平面在偏移距离107处。
图1示出了管状结构的第一纵向部分204和第二纵向部分205。如关于图5b所描述的，第二纵向部分205包括在管状结构的径向方向110上厚度增加的部分203。管状结构200沿纵向方向103被传送，使得第一纵向部分204在第二纵向部分205之前定位在成形环100处。方法300可以包括形成302包装材料的管状结构200的第一纵向部分204，其中在纵向接合表面201,201'之间具有限定的搭接部分(L)，如图5a所示。方法300可以进一步包括通过接合纵向接合表面201,201'密封303第一纵向部分204，以便固定304限定的搭接部分(L)，并输送305管状结构200的第二纵向部分205通过开口102。第二纵向部分205包括在管状结构200的径向方向110上厚度增加的部分203，如图5b所示，由此方法300包括当通过开口102输送时，暂时相对于限定的搭接部分(L)增加306第二纵向部分205的纵向接合表面201,201'之间的搭接部分。方法300随后可以包括将第二纵向部分205传送307到至少一个密封构件105,106处，在至少一个密封构件105,106处的纵向接合表面201,201'之间的搭接部分调节308到所述限定的搭接部分(L)，并且通过接合纵向接合表面201,201'来密封309第二部分205，以固定310所述限定的搭接部分(L)。在至少一个密封构件105,106处的纵向接合表面201,201'之间的搭接部分可以重新呈现限定的搭接部分(L)，因为由旋转成形构件101施加的约束已经在偏移距离107处去除。方法300因此使得能容纳管状结构200的厚度增加的部分，同时允许通过旋转成形构件101使其精确成形，并且将纵向接合表面201,201'牢固地密封，使得包装材料的有害变形的风险最小化。
至少一个密封构件105,106可以可旋转地布置到成形环100，由此至少一个密封构件105,106的旋转轴线111,111'可以相对于第一平面104以偏移距离107布置，如图2的示例所示。这提供了在可旋转的至少一个密封构件105,106上传送的纵向接合表面201,201'的可靠密封。然而，可以想到的是，至少一个密封构件105,106包括配置成沿纵向方向103密封包装材料的其他密封单元。纵向接合表面201,201'可以通过粘合材料和/或感应焊接和/或热空气密封。所述至少一个密封构件105,106因此可以包括感应器，该感应器被布置成抵靠包装材料并且被配置为在包装材料的金属箔中感应出交流电，从而引起材料加热并且熔合相对布置的纵向接合表面201,201'。包装材料可以通过抵靠感应器的焊接表面滑动而在纵向方向103上传送，所述感应器在纵向方向103上相对于第一平面104布置在偏移距离107处。
所述至少一个密封构件105,106可以包括第一旋转构件105和第二旋转构件106，所述第一旋转构件105和第二旋转构件106布置成在使用时将包装材料夹在它们之间以沿着纵向接合表面201,201'将其密封。如在例如图2中所示，管状结构200的包装材料位于第一旋转构件105和第二旋转构件106之间。纵向接合表面201,201'可以设置有粘合剂材料，例如布置在其间的粘合剂或沿纵向接合表面201,201'布置的粘合剂材料条。在将纵向接合表面201,201'压靠在第一可旋转构件105和第二可旋转构件106之间的粘合材料上时，纵向接合表面201,201'可以彼此附接并密封。可以设想的是，至少一个密封构件105,106包括以与在图2的示例中示出的结构不同的结构布置的旋转密封构件，例如所述旋转密封构件相对于成形环100以不同的数量或不同的取向布置，同时沿纵向方向103相对于第一平面104设置在偏移距离107处。
第一可旋转构件105和第二可旋转构件106可沿纵向方向103布置，使得包装材料在使用中相对于第一平面104在偏移距离107处被夹紧。这可提供纵向接合表面201,201'的优化的密封，因为它们的搭接部分可以在成形构件101的平面104中暂时增加之后在偏移距离107处再次呈现预定的设定搭接部分(L)，如关于图5a-b所描述的。然而，可以想象的是，包装材料可以(例如，通过使第一可旋转构件105和第二可旋转构件106中的一个在纵向方向103上相对于另一个偏移)在纵向方向103上与旋转轴线111,111'中的任一个分开的位置处被夹紧。这种偏移可以改变以提供第一可旋转构件105和第二可旋转构件106相对于彼此的可调整对齐，例如，以便根据应用和所使用的具体包装材料实现最佳的管状成型和密封程序。
旋转成形构件101的相应旋转轴线101'可以布置成在第一平面104中延伸。图2结合图4示出了旋转轴线101'在基本上相同的平面104中对准。为了清晰表述起见，并没有指示全部旋转轴线101'。使旋转轴线101'在基本上相同的平面104中对准可以提供在成形过程中精确地控制管状结构200的尺寸，但可以设想至少一些旋转成形构件101以及其相关的旋转轴101'可以在平面104外部对准，以根据具体应用和包装材料优化成形和密封过程。
旋转成形构件101可布置成限定开口102的周边108，使得成形环100包括在所述平面104中从周边108沿径向向外方向110延伸的径向间隔109，其中至少一个密封构件105,106布置在偏移距离107处。图3示出了沿输送管状结构200的方向(即，纵向轴线103的方向)在成形环100下游的位置观看的透视图。在至少一个密封构件105,106上方示出了径向间隔109，其在图4的俯视图中进一步示出。在成形环100的平面104中具有这种径向间隔109提供了空间，当由于厚度增加的部分203与旋转成形构件101接合而被径向向内推动时，包装材料可暂时移动到该空间中(沿图5b中的径向箭头110的方向)，如相对于图5b所图解的。因为厚度增加的部分203穿过成形环100的开口102而在纵向接合表面201,201'的搭接部分的增加的量可以因此减小。因此，随着搭接部分的波动减小，可以进一步减小密封时包装材料变形的风险。
转到图4的示例，径向间隔109可以在正交方向112上具有宽度，该宽度垂直于径向向外方向110和纵向方向103，对应于至少一个密封构件105,106在正交方向112上的宽度113。这可以使得径向间隔109的宽度最大化，并且进一步便于包装材料在被成形构件101接合时适应该包装材料在径向方向110上的增加的运动量。宽度113仍然可以足够窄以维持管状结构200的明确限定的直径。
成形环100可以包括安装元件114，如图2中示意性示出的那样，该安装元件被配置成将至少一个密封构件105,106沿着纵向方向103附着在可变位置和/或沿着垂直于纵向方向103的方向(例如径向方向110)附着在可变位置。密封构件105,106的对准因此可以容易地改变，以将成形环100定制用于各种应用和包装材料，例如设置有不同的开启机构-从而影响厚度增加的部分203的尺寸(图5b)。包装材料的径向位移和搭接部分中的相关波动可通过安装元件114的位置的简化调节而进一步最小化。
如图4所示，第一可旋转构件105可以包括布置在成形环100在开口102的周边108的径向外侧处的第一辊105。第二可旋转构件106可以包括可附接到填充管202(图1)的压力辊106，填充管202布置在包装材料的管状结构200中，如在图4的俯视图中进一步例示的那样。压力辊106因此可以如上所述从包装材料的任一侧抵靠第一辊105推压以将包装材料密封在一起。
提供了一种填充机(未示出)，其包括如上面参照图1-图5所述的成形环100和包装材料，该包装材料在通过旋转成形构件101限定的成形环100的开口102中成形为管状结构200。旋转成形构件101布置在第一平面104中，并且管状结构200沿纵向方向103延伸。至少一个密封构件105,106配置成在使用中在将包装材料在开口102中成形为管状结构200之后密封管状结构200的纵向接合表面201,201'，其中至少一个密封构件105,106在纵向方向103上相对于第一平面104布置在偏移距离107处。填充机300因此提供如上面关于图1至图6所述的有利效果。
本发明已经参考具体实施例进行描述。然而，除上述之外的其它实施例同样可能在本发明范围内。本发明的不同特征结构和步骤可以除了所述那些之外的其它组合方式进行组合。本发明的范围仅由所附专利权利要求限定。
更一般地，本领域技术人员将容易理解，本文所述的所有参数、尺寸、材料和结构都旨在是示例性的，并且实际参数、尺寸、材料和/或结构将取决于本发明的教导内容所用的一个或多个具体应用。
