Description
本发明涉及一种权利要求1前序部分用于将多层物(Multilayer)步进层叠的装置。
这类装置也称「阶段压机」(Stufenpresse),因为一条层叠物(Laminiergut)步进地运送通过先后相继设置的挤压机构(挤压步进),这些挤压机构各将数个随后的多层物容纳及压合。该挤压机构具有加热及/或冷却装置,且可单个地或成组地调节。在各挤压机构中,将该构成多层物的层叠物压迫并加热至一预定温度或冷却,如有必要,在所有挤压机构共同开放之前保持在此温度上一段预定时段,并将该叠物再运送一步,例如再运送一个挤压机构的距离。为了运送,在该层叠物上侧及下侧设有两条输送带,其运送回行段(Trum)通过所有挤压机构,且在挤压机构两端绕过偏转滚子运转。
多层物一般有一内层,它宜在上下侧各层叠上一个外层。该内层一般也可称为载体。外层在多层物中有一金属膜,一般由铜或铝构成,在层叠后,利用蚀刻由该金属膜制造出印制线路。为了作层叠(将外层与内层粘合),将一个或数个中间层放到外层与内层之间,该中间层由可受热及压力熔化的绝缘塑料构成。在多层物中,这些中间层一般称为预浸渍体(Prepreg)。它们可呈单纸片(Bgen)或分立的带子形式或呈附着在金属膜上的带子组合形式供应。在后者的情形也称为复合膜(Verbundfolie)。为了要能将数个金属层层叠到该内层的上下侧,可重覆此层叠过程,其中,该位于外侧的金属层在将另一中间层及外层叠之前,须蚀刻成印制线路。在层叠后将该层叠物切分成板,这些板包含整数个后来制成的多层物。这些层叠板在进一步层叠通过时,变成内层。
这些内层单个地呈板形式供应,或者第一次层叠通过之时也可呈条带的方式供应。外层与中间层一般呈条带的形式供应,基本上也可考虑将单个的层片叠放上去。
除了多层物外,利用本发明的装置也可制其他的层叠物,就是说,例如制造信用卡或金融卡用的层合板。层叠作业一般在一抽成真空的空间中进行,挤压机构设在该空间中。在该挤压机构中利用压力与温度的作用,使内层熔化,如有中间层,则连中间层也熔化,在冷却后在最后一个或几个挤压机构中将该层叠物的层以材料接合的方式相互接合。
本发明的目的是提供一种多层物或通常的层复合材料的步进层叠的装置,它不需要连续的输送带将层叠物运送通过挤压机构。
该目的依本发明利用权利要求1的特征实现。本发明的装置有至少一个沿运送方向的最后的挤压机构,它可沿着或逆着运送方向运动。也可以有数个最后的挤压机构共同运动。为了要将层叠物运送通过这些挤压机构,除了该可运动的最后数个挤压机构之外,将所有的挤压机构开放,且使关闭的可运动的挤压机构沿运送方向移动一个或数个挤压机构的长度(亦即移动一步)。如此带状层叠物被运送通过该装置一步。随后将这些开放的不运动的挤压机构关闭,将可运动的挤压机构开放并在它们再度关闭之前移回其起始位置。因此,这种层叠物呈步进方式通过挤压机构的作业依本发明,是藉助最后数个挤压机构沿运送方向移动而实现的。为此,至少该多层物的或层叠物的最下层须为一条连贯的带子,它通过所有的挤压机构。最好,该层叠物的最上层也是一条连贯的带子,以避免该挤压机构开放时附着在挤压机构的上压模上。该层叠物的所有其他的层可为贯行的带及/或板或层片,它们位于最下方的带上并随之呈步进式运送通过这些挤压机构。
本发明的主要优点是,它不需单独的输送带,这种输送带另外还需要各二个转向滚子以及一般的张紧装置。另一优点为:挤压机构直接将层叠物加热或冷却,亦即不用位于其间的输送带,如此使热传递改善。
本发明的一种优选方案是有一导离装置,它沿运送装置设在最后的挤压机构之后,且至少一个最外层在层叠之后从该层叠物去掉。该最外层可为一个具有多个层的外层的其中一个层。因此,在此情形中,可供应一复合膜当作外层,举例而言,该复合膜具有一金属膜及一个或数个塑料膜,其中,在层叠后,最外面的(塑料)层再除去。也可供应数个外层,或外层与中间层,其中最外层在层叠后再除去。所要除去的层其熔点优选较高,换言之,它在加热及加压时不熔化,而即使在层叠后,也只附着在层叠物上,而不会和层叠物有材料接合(熔接成一片)的情形。因此最外层也可由金属(铝箔)构成。最好,将层叠物的上侧及下侧上的最外层从该层叠物除去。
该供应及导离装置例如有一卷取机构,外层由此卷取机构卷离或被卷取到其上。导离装置另外有一旋转驱动器以将最外层卷取起来。依本发明在层叠后从层叠物上去掉的最外层有一优点,即可避免层叠物污染。该最外层呈新鲜未受污染的方式供应到挤压机构,且在层叠后就拿掉。在连续的输送带所必需的清洗作业可以省却。污染颗粒被带入挤压机构的情形可避免,而在连续的输送带的情形这点常会发生。因此这点是一大优点,因为即使有最小的污染颗粒,都会使多层物或其他层状物如信用卡及金属卡不以使用。由于省却了在连续的输送带不能缺少的清洗装置,因此本发明这种在层叠后将最外层从层叠物分离的方式可使层叠装置更廉价。此外由于污染造成废品的风险可大为减少。另一优点为,省却了连续输送带的回行段,因此该挤压机构较易够及而且调整较简单,其结构造也较简单。
本发明的一种方案还有一切分机构,在层叠以及最外层除去后,它将层叠切分成板或层片,它们包含数个多层物。
本发明在以下利用附图所示实施例详细说明。附图示出了本发明的用于将多层物步进层叠的装置的简化示意图,各图按作为顺序排列。
图示的本发明的层叠装置10用于将多层物12作步进式层叠。该层叠装置10有四个挤压机构14,16,它们沿一运送方向前后设置。每两个挤压机构14,16平行操作,一个层叠物18在每个程序步骤中再运送两个挤压机构14,16的长度。
两个沿运送方向为第一的挤压机构14有加热装置,两个最后的挤压机构16有冷却机构。两个最后的挤压机构16可共同地移动两个挤压机构14,16的长度,换言之,沿着或逆着运送方向移动一步(见图1,2)。设置每两个平行操作的挤压机构14,16可提高该层叠装置10的通过量。原则上也可以分别设单个的挤压机构,层叠物可在先后相随的挤压机构中步进式地加热到高温并再冷却下来(图未示)。
具有先后相随的挤压机构14,16的层叠装置10也可称为阶段压机,在图式中运送方向由左往右。
板状内层20作为层叠物18供应到挤压机构14,16。此内层20例如通常由一个用树脂浸润的玻璃纤维布构成,其树脂受温度及/或压力作用而溶化,然后硬化。此内层20电绝缘。例如,有一输送带22用作供应内层20的机构。此内层20跑到第一挤压机构14前一个下方的外层带24上,该外层带24由一储存滚子26卷离,并经转向滚子28送到挤压机构14,16。储存滚子26与转向滚子28构成一供应机构以供应下面的外层带24。外层带24由一金属/塑料复合膜构成,它有一金属膜,例如由铜制成,附在一塑料膜25(例如由聚酯制成)上。外层带24的塑料膜25的熔点比内层20高。外层带24的供应方式使金属膜位在上方,换言之,内层20靠在外层带24的金属膜上。
一上方的外层带30从一储存滚子32卷离,并经由转向滚子34靠在内层20的上侧送到该挤压机构14,16。储存滚子32与转向滚子34构成上方的外层带30的供应机构。上方的外层带30与下方的外层带24一样为一复合膜,且有一例如由铜制成的金属膜,它附着在一塑料膜31上(例如由聚酯制成)。上外层带30的供应方式,使金属膜位于下方且靠在内层20上。
在图1所示的第一程序步骤,所有四个挤压机构14,16都关闭,而在两个第一挤压机构14中层叠物18在压力下加热直到内层20熔化。在两个最后的挤压机构16中,层叠物18冷却下来,因此内层10的树脂硬化,而与外层带24,30的金属膜呈材料接合的方式连接。外层带24,30的塑料膜25熔点比内层20高,不熔化。
在图2中所示的第二程序步骤中,两个第一挤压机构14开放,而可动的最后两个挤压机构16移动了两个挤压机构14,16的长度,亦即沿运送方向移动了一步。如此该层叠物18被层叠装置10运送了两个挤压机构14,16的长度。在图3所示的第三程序步骤中,两个第一挤压机构14再关闭,并将层叠物18加热。两个最后的挤压机构16开放(图3)且在两步中逆着运动方向回移了一个挤压机构14,16的长度回到该两个第一挤压机构14。关闭的挤压机构14将层叠物18保持住,因此它不会被逆着运送方向回移的最后的挤压机构16推回去。
在最后的挤压机构16沿运送方向的后端上设有一个切分机构36,它具有两个刀具,随可动的挤压机构16一同移动。切分机构36在内层20之间的一中间空间中在每次回移步骤后将层叠物18切成板,该板含有多层物12,且在层叠装置10的末端构成两个料堆。各板可有一个或数个事后要分开的多层物12。图4及图5中显示切成两个具有多层物12的板的情形。
在层叠之后,将外层带24,30的塑料膜25,31从层叠物分离。这通过卷取到卷取滚子38,40上而实现,该卷取滚子有旋转驱动器(图中未示)。卷取滚子38,40设在装置10末端在层叠物18的上方及下方。塑料膜25,31可从层叠物18撕离,因为外层带24,30的塑料膜25,31的熔点比内层20的树脂高,且挤压机构14,16中的层叠物18并未加热到外层带24,30的塑料膜25,31的熔点。因此,该外层带24,30的塑料膜25,31在层叠后只附着在该层叠物18,且不与层叠物18呈材料接合的方式接合。因此塑料膜25,31在层叠后可从层叠物18撕离而去除。
当最后两个挤压机构16沿运送方向运动时,外层带24,30的塑料膜25,31绕过最后的挤压机构16的后缘,且由于挤压机构16的运动而从卷取滚子38,40卷离,如图2所示。在此该卷取滚子38,40可自由转动或可被制动。当最后两个挤压机构逆着运送方向16回移时,卷取滚子38,40受驱动而旋转,并将塑料膜25,31卷取起来。塑料膜25,31在最后的挤压机构16与切分机构36之间盘绕,因此它们在层叠物切分成多层物时不会被切断。因此,外层带24,30的塑料膜25,31从储存滚子26,32卷离,且在层叠后卷取到卷取滚子38,40上。卷取滚子38,40与图中未示的旋转驱动器构成一导离装置的卷取机构,将外层带24,30的塑料膜25,31导离。塑料膜25,31用于保护层物18免受污染,它们以新制成无污染的形式从储存滚子26,32卷离。
构成外层24,30的复合膜的塑料膜25,31构成外层带24,30的最外层25,31。如不使用复合膜作外层带24,30,金属膜与塑料膜也可从分开的储存滚子卷离,并送到挤压机构14,16(图中未示)。在层叠后,通过卷到卷取滚子38,40上将塑料膜从层叠物18去掉的作业则保持不变。在此情形,塑料膜可当成外层带的数个外层之一收集。
