Abstract

提供了用于把织物(12)的有接缝的接头的接缝裕量引导成在结合辊隙中与施加于所述有接缝的接头的接缝密封带(18)纵向对准、以实现接头的防漏密封的装置。该装置包括定位成在接近结合辊隙的进口附近靠近结合辊隙的引导装置(30)。引导装置(30)有一个供接缝裕量进入并从其中通过的开口(31)。开口(31)的尺寸足以接纳和引导接缝裕量从其中通过。开口(31)较佳地是一个口，口的开口端定位成在密封带和有接缝的接头进入并通过结合辊隙时接近有接缝的接头并对准密封带。引导装置还可选用地包括与之协同动作的冲击吸收装置(68)。

Description

用于在接缝密封中引导接缝裕量的装置和方法
技术领域
本发明涉及用于密封织物、诸如防水服装之类的起隔绝作用的防护性织物上的接缝的方法和装置，以使这类织物的有接缝的接头处不透水，在这类接头处，织物的相交的裁片或条块是通过诸如缝制、粘合或焊接之类的方法接合在一起。缝制(或做得不好的粘合或焊接)在这类接头处会留下穿过服装的孔和/或空隙，要想保持作为一个流体隔绝物的整件服装的完善性，必须密封住那些孔和空隙。
背景技术
防护性服装和类似物品上的、把相交的衣服裁片缝制在一起形成的接头处的接缝的密封是已知的。在这类有缝制的接头处，各织物的裁片一般并不搭叠，而是对接在一起，形成一个基本上垂直于织物裁片的平面延伸的延伸部分，缝线处在延伸部分的根部。这条缝制时留出的延伸部分被称为“接缝裕量”。
典型地，是把与防护性隔绝织物是或者不是同一种材料的密封带沿着服装上的每一条接头附着在服装上，以遮盖并密封住接缝。这些密封带可以是热塑性材料的，可以用诸如热风枪等进行加热，使密封带软化/熔化到发黏的状态，而后把它贴附在接缝处而密封住接头。此外，也可以用涂有粘合剂的基带。已知的粘合剂包括热塑性的和热熔性的聚氨酯粘合剂、某些胶水、以及近来发现的适用于这一用途的硅酮粘合剂。
采用接缝密封的防护性物品包括诸如雨衣的防水服装和用于户外活动的帐篷。在手术室里穿的罩衣也要密封，以保护穿着者免于接触含有病原体的血液和其它体液。消防队员的工作服必须能提供全面的保护，以防止其在任何救火环境中可能遇到的水、病原体和各种化学品的可能渗透。
接缝密封往往还必须承受不利的环境条件。例如，消防队员的防护服，包括其上的接缝，必须能承受高温而不熔化。对于外科手术防护服上的接缝，需要其能经得起大量次数的热高压灭菌消毒，同时能保持其隔绝性能。
一般地说，防护性服装可以制作成包括一个特殊的防护性隔绝层和其它的覆盖层或载体层，诸如衬层或贴边织物层。在这类服装中，防护性隔绝层保护穿着者免受诸如雨、雪、化学品、病毒或血液中的病原体等存在物的威胁。这类隔绝层的例子包括微孔聚四氟乙烯薄膜、微孔的或单片的聚氨酯膜、以及聚醚聚酯膜。可以把防护性隔绝层贴附于或层压于一层或几层通常是纺织物或编织物的高强度的耐磨的衬层。在这样的构造中，常用的衬层是尼龙和聚酯织物。
防护服可以通过把防护性隔绝织物的裁片缝制成所需要的服装形状而做成。各裁片之间的接头和隔绝层的其它中断处必须密封，以使其隔绝作用比得上防护性隔绝织物的本身。这一般是通过把密封带贴附在接缝处来实现的，就像前面已讨论的那样。
防护性隔绝服装的接缝密封工艺过程一般包括通过在一个结合辊隙中将密封带结合(consolidate)在接头上。结合辊隙一般由两个相对的辊子构成。
美国专利No.6,032,714和这里引用的其它参考文件揭示了用于进行接缝密封的各种工艺过程和装置，并且介绍了这一技术领域的现况。在已知的接缝密封技术方法中，在把密封带贴到有接缝的接头上时很难使密封带的中心线精确地对准接缝。随着接缝裕量在通过结合辊隙的过程中被折叠，其可能干扰密封带向接头的准确贴附。如果对接缝裕量不加引导，它可能沿着接缝东倒西歪，一会儿倒在接缝的这一边，一会儿又倒在接缝的那一边，使得接缝本身相对于贴附的密封带的中心线拐来拐去，反之亦然。在进行接缝密封之前把接缝裕量压倒缝平或粘合或焊接于接缝的一侧，可以防止这种东倒西歪的现象，但是，如果用的接缝密封带较窄，接缝裕量也更窄，把接缝裕量压倒缝平较难而且很费时间。对于较窄的接缝密封带，更需要保持接缝裕量(不管是压倒缝平与否)对中于接缝密封带的中心线。
与已有技术相比，本发明提供一种用于引导织物上的有接缝的接头的接缝裕量的工艺过程和装置，用这种方法和装置可使接缝裕量纵向地对准贴附于接缝的接缝密封带。使得在被密封了的有接缝的接头中接缝沿着纵向对准密封带。
发明内容
提供了用于把织物的有接缝的接头的接缝裕量引导成在结合辊隙中与施加于所述有接缝的接头的接缝密封带纵向对准的装置。该装置包括一个定位成在接近结合辊隙的进口处靠近结合辊隙的引导装置，引导装置有一个供接缝裕量进入并从其中通过的开口。开口的尺寸足以接纳和引导接缝裕量从其中通过，开口定位成在密封带和接头进入和通过结合辊隙时接近接头并与密封带对准。在各较佳实施例中，织物是防护性隔绝织物，开口是一个槽口。引导装置可以选用地且较佳地固定于与之协同动作的冲击吸收装置。在使用中，有接缝的接头和接缝密封带在通过结合辊隙并被在该处结合时，形成密封的有接缝的接头，使得接头的接缝和密封带纵向地对准。在一个实施例中，使接缝沿着密封带的中心线对准。导槽较佳地从其开口端起定向为从织物的平面向上成一角度地延伸，这个角度较佳地是在30°和150°之间，最佳的角度是45°。可选用的冲击吸收装置可以是一个弹簧加载的冲击吸收支承框，该支承框固定成接近结合辊隙，引导装置安装在这个支承框上。
引导装置可以永久性地(例如焊接上去)或者可拆装地(例如用螺栓连接、夹紧连接等)安装于支承框。引导装置可以可转动地安装于支承框，以便能改变槽口的角度，例如通过简单地转动引导装置将其从30°转到150°。
在一个较佳实施例中，接缝密封带是热塑性密封带，其密封用加热措施、诸如热空气流来实现。或者，接缝密封带可以是其上涂有粘合剂的背衬带。一种较佳的粘合剂是硅酮粘合剂。也可以用任何其他适当的密封带。
接缝密封带的宽度可以根据接缝裕量的高度来选择。通常接缝密封带的宽度小于约25mm，较佳的是小于约17mm，更佳的是小于15mm，最佳的是不超过约13mm。接缝裕量的高度较佳的是小于6mm，更佳的是小于3mm，最佳的是不超过2mm。
此外，本发明提供了用上述装置对防护性隔绝织物的有接缝的接头施加接缝密封带、以实现接头的密封的工艺过程。

具体实施方式
本发明提供了用于引导织物的有接缝的接头的接缝裕量的装置和方法，用这种装置和方法可使接缝裕量在一个结合辊隙内沿着纵向对准施加于有接缝的接头的接缝密封带，而实现接头的防漏密封。该装置包括安装成在接近结合辊隙的进口处靠近结合辊隙的引导装置，接缝裕量将进入并通过结合辊隙的这一进口。引导装置有一个开口，其尺寸足以接纳和引导接缝裕量从其中通过，这个开口定位成接近有接缝的接头并在密封带和接头进入和通过结合辊隙的过程中对准密封带。较佳的是，这个开口是一个槽口。“槽口”这个术语包括凹槽和各附图中描绘的其它形状的开口。
引导装置可以包括与之协同动作的冲击吸收器。
在有接缝的接头和接缝密封带通过结合辊隙的路径上以及它们在结合辊隙处被结合时，可产生一接缝的接头，该接头的接缝沿着密封带纵向对准。较佳的导槽从其开口端开始定向为从织物的平面向上成一角度地延伸。导槽可迫使接缝裕量倒向服装的一侧，并且导槽定位成使接缝裕量的中点，也就是接头接缝和接缝裕量的外边缘之间的距离的一半那一点，定向为基本上纵向地沿着密封带的中心线，也就是使密封带和接缝裕量共同对中。导槽的这个角度较佳的是在30°和150°之间，最佳的角度是45°。可以用热塑性的密封带、涂有粘合剂的背衬带、或任何其他适当的密封带。较佳的是，密封带的宽度不超过13mm。
下面参照各附图对本发明及其各较佳实施例进行最好的详细说明，各附图中，图1以立体图表示出本发明的装置10的全部各组成部分，该装置可用于引导有接缝的接头的接缝裕量，使接缝对准接头密封带。为了表示得清楚，图1中省略了其接缝将被密封的织物。
图1中，装置10包括安装在支承架48上的供带辊22，背衬带18被从供带辊22上拉出来。密封带18由销轴51和惰辊38引导后，在导带件34的下面和导带件32的上面进入上结合辊隙辊24和与之相对的下轧辊26之间的辊隙。上轧辊24和导带件32以及导带件34一起构成一个这里称为“纬管(quill)”的部件，其可以在双向箭头所指的方向进行空间位置调整，其连接于驱动器47并可由它驱动，它在工作过程中的位置由操作者用结合入驱动器47的一止动块来设定。可把这个上组件按照预先确定的设定值向下降，使上轧辊24相对于下轧辊26定位成两者之间有一个所需要的预定间距，以实现密封带18的前进以及把工件进给到上轧辊24和下轧辊26之间的辊隙。
参照图1，在本发明的工艺过程中，从供带辊22沿着箭头的方向进给接缝密封带18，绕过通过支架50安装在固定的支承架48的支架50上的导销51，然后绕过惰辊38和导销58而进入并通过导带件34。从导带件34，密封带在辊32之上被进给入上轧辊24和下轧辊26之间的结合辊隙。在其间它被结合于有接头的织物(图1中未示)。
一个支承框28固定于所谓的纬管部件，而接缝裕量引导装置30可以永久性地或者可拆装地固定于这个支承框28。这一组件可包括可选用的冲击吸收装置，这将在下面更详细地讨论。
驱动轧辊24和26的驱动机构用齿轮连接于执行器47和主支承箱体54，主支承箱体上有控制台56，控制台里装有驱动控制器和加热控制器。在采用热塑性密封带18时，可用所示的热风枪40加热处在轧辊24和26之间的辊隙里的密封带18，使它软化并发黏。热空气源42是用支架52安装于支承框54，并且热风枪40的喷嘴根据需要使热空气对准结合辊隙和密封带。
为了完整性，整个上述装置描绘为安装在一个工作支承表面44上。支柱46为被送进轧辊24和26之间的辊隙的有接头的织物工件提供部分支承。
图2的立体图示意地表示出有接头的织物工件通过密封工艺过程的情形。该图中，两个织物裁片12，12在接缝14处接合(例如缝制，粘合，焊接)在一起，并且两个织物12的在接缝14之外的延伸部分对接在一起形成接缝裕量16，其被密封带18沿着接缝14盖住。织物裁片12，12的行进方向和密封带18的贴附方向如图中的粗体箭头所示。在施加密封带18的过程中，接缝裕量16被折平到两个织物裁片12之一上，如图2中的弯曲箭头所示，随后密封带18被施加于其上，结果就形成一个完工的被密封的接缝20。
尽管已经结合图1和2说明了热塑性的密封带，但是，熟悉本技术领域的人很清楚，也可以用其它类型的密封带，诸如涂有粘合剂的密封带，或者是在结合辊隙内时把粘合剂涂在背衬材料上的带子。本发明不限于具体的密封带类型，而是本发明可以应用于在接缝密封作业中需要把接缝裕量16引导为对准密封带18的任何场合。
接缝裕量引导装置和将被密封的有接头的织物接缝的更详细情况示于图3。其中，两块织物裁片12，12之间的接缝裕量16表示为即将进入上轧辊24和下轧辊26之间的辊隙。有接缝的接头的进给方向如图中的粗体箭头所示。同时，密封带18也进入结合辊隙并将被引导覆盖在接缝14和接缝裕量16上。图4是本发明的装置的一个进一步放大的视图，表示出接缝裕量16就要进入其引导装置30。同样，织物接头14和密封带18的行进方向也都如粗体箭头所示。接缝裕量引导装置30表示为固定于支承框28，而支承框28是通过开槽的托架29可调整地固定于架座55。如图所示，支承框28是用螺栓连接于上轧辊24。图4中未表示出来的一个可选用的吸收冲击的弹簧是安装在支承框28和托架29之间，这个弹簧能够有效地吸收有接缝的接头在通过接缝裕量引导装置30时遇到的冲击，这将在下文说明。
图5表示出在本发明的装置上有接缝的接头已经部分地通过接缝密封过程以及已经形成了被密封的接头20。图3、4和5中的其它零部件与上面讨论的相同。下面说明一个较佳实施例中的接缝裕量引导装置30。
图6表示出本发明的接缝裕量引导装置30的一个较佳实施例。一般地说，引导装置30是固定于支承框28。在这一较佳实施例中，也示于图5，引导装置30有机械加工于其上的导31，在进行密封过程中，接缝裕量16被引导穿过导31。引导装置30上的导31对通过它的接头的织物的平面有一个约为45°角度。导31把从其中通过的接缝裕量16折平，随后密封带18盖在接缝裕量16上，同时产生(迫使)接头接缝14和密封带18沿着纵向的对准。导31的前边缘可以略微倒圆，以使接缝裕量16容易进入导31。
图6A和6B表示出接缝裕量引导装置30的替代结构，其中引导装置30的导311和312对在这一构造中通过结合辊隙的织物的平面的角度分别为90°和135°。尽管描绘了导的特定角度，但这在任何方面来说都不是限制性的。按照作为本发明的基础的原理，在接头密封中可以用30°和150°之间的任何角度。
图6C-6H描绘了引导装置30的几个可替代的实施例，它们分别有不同的可以接受的开口结构。图6C中，开口313是矩形的，而在图6D-6H中，开口314到318分别是有锥度的、半圆的、两个协作的滚子之间形成的空隙、圆锥形的半园、以及一个倒L形的托架。注意图6F中两个滚子80是安装在同一根轴28′上。
图7和8分别是有接缝裕量16的有接头的织物裁片12的左侧视图和右侧视图，其正在由引导装置30引导通过上轧辊24和下轧辊26之间的辊隙，从两个轧辊之间出来时就变成了接缝接头20。冲击吸收装置与引导装置30协同动作，例如引导装置30是安装在支承框28上，而支承框28是可转动地安装于上轧辊24并且用螺栓64连接于开的框架29。框架29上有调整和定位螺栓64和66可穿过的60和62。弹簧68(见图8)安装在螺栓64和66之间，可以把这两个螺栓固定和收紧在60和62里的所需要的位置，以便调整弹簧68的拉力，而弹簧又对引导装置30和通过它的接缝接头施加主动的、可调整的压紧力，如图8中的箭头所示。冲击吸收装置能够吸收织物接头通过引导装置30时遇到的冲击而有效地降低或消除冲击对密封过程的不利影响。
本发明的方法和装置有许多优点。例如，由于能够把接缝裕量不变地地压平于接缝的一侧，生产的服装特别有吸引力；由于能够消除接缝裕量向接缝两侧东倒西歪的现象，可以生产出更加美观的服装；可以用较窄的接缝裕量和较窄的接缝密封带，因而可节省织物和接缝密封带，降低生产成本，还可以减轻服装的重量，还可以进行更快更能保证质量的生产；也大大地改善了对比较麻烦的弯曲接缝进行密封的能力。
尽管本发明的各零部件的材料不是关键性的，但是，熟悉本技术领域的人能够理解，这里描述的支承框28和接缝裕量引导装置30最好是用钢材制造。
尽管已经以几个实施例详细地说明了本发明，但是，熟悉本技术领域的人很清楚，它们可以在本发明的精神要义范围内对那些具体结构做出各种变型或改变，因此，这些变型和改变都将被认为是属于权利要求书的范围之内。
